It has been developed a small-scale, simple, and rapid diffusing liquid-liquid microextraction ( DLLME ) process in combination with fiber optic-linear array sensing spectrophotometry ( FO-LADS ) with charge-coupled device ( CCD ) sensor profiting from a micro-cell. The official mention methods ( ASTM D2330 – 02, ISO 7875-1 ) which require boring processs were replaced with modified method, as a consequence, it has achieved a major decrease in sample size, riddance of the usage of expensive glasswork, and a lessening in the measure of trichloromethane used every bit good as much more addition in sensitiveness. Our presented method requires merely one twentieth of sample ( 5.0 milliliter ) , less than one three-hundredth of microextraction dissolver ( chloroform = 138 A µL ) , and much reduced in analytical clip compared with official analytical methods ( less than one minute ) . The standardization curve was additive in the scope of 0.06 A- 10-1 – 0.8 A- 10-1 milligra m La?’1 of Na dodecyl sulphate ( SDS ) with a correlativity coefficient ( R ) of better than 0.99 and the LOD was 0.02 A- 10-1 milligram La?’1. The repeatability of the proposed method ( n=7 ) were found to be 4.5 and 3.6 % for the concentration of 0.03 and 0.07 milligram La?’1, severally. The enrichment factor was found to be 75 for SDS.

IntroductionA turning public concern over protecting our environment obligate chemists, including analytical chemists, to alter their activities in such a manner that they will be conducted in an environmentally friendly mode. Sampling, and particularly sample readying, often involves coevals of big sums of pollutants. This is why sample readying techniques that use a little sum of organic dissolver, or none at all, have been developed [ 1-4 ] . Anionic wetting agents ( AS ) are widely used in family cleaners, industrial detergents and decorative preparations. The wetting agents expelled to natural H2O reservoirs as municipal and industrial wastes are good known to hold inauspicious effects on aquatic beings ; hence the monitoring of wetting agents in environmental samples is of great importance [ 5, 6 ] . For the measuring of entire surfactant concentration, titration methods have been extensively explored [ 7, 8 ] . Several ion-selective electrodes sensitive to anionic wetting agents have been reported so far [ 9-11 ] . Anionic wetting agents are normally determined by spectrophotometric methods utilizing methylene blue ( MB ) , this standard methods being used to find AS in the surface and tap-water samples ( ASTM D2330 – 02, ISO 7875-1 ) [ 12, 13 ] . The method is based on the formation of blue-coloured trichloromethane extractible ion-pair between the AS and the cationic MB. This requires three consecutive extractions of AS-MB content in 100 milliliter of sample with 15, 10, and 10 milliliter of trichloromethane. The ion-pair is determined by spectrophotometry, mensurating the optical density at 650 nanometer. However, these official methods are non merely long and boring but besides require great measures of sample and trichloromethane which has harmful consequence on chemists and environment. Besides, this method needs batch of research lab glasswork, do these operations highly expensive and uncomfortable for the operator. So it seems necessary to seek for new offers as options for the a foresaid method in order to increase the laboratory productiveness, operator safety, comfort, and to cut down drastically the reagents ingestion and waste production. Koga et Al. proposed a decrease of the size of sample employed for AS finding in H2O, being modified this method to utilize 50 milliliter of H2O and 5 milliliter trichloromethane, holding obtained a six times addition of the research lab productiveness [ 14 ] . An other simplified methods that cut down the measures of reagent by utilizing a certain sort of adsorbent have been proposed [ 15 ] . However, this method besides involves boring processs. Besides other research workers studied primary biodegradation of AS in aerophilic showing trials based on the formation of ion-pair of AS and MB [ 16 ] . By early 2006, Assadi and his research group innovated an attractive, high public presentation and powerful liquid-phase microextraction ( LPME ) method which named their techniques â€Å" Diffusing liquid-liquid microextraction † ( DLLME ) [ 17-19 ] . Beyond the trait of simpleness of operation and celerity, ingestion of microextraction dissolver at the micro-level volume and compatibility with analytical instruments are other profitable characteristics of DLLME as a sample pretreatment method [ 20-25 ] For extremely sensitive, accurate, rapid, and cheap measuring with ingestion of extraction dissolver at micro-level volume, we propose a simplification of the spectrophotometric MB method that can be utile for finding anionic wetting agents in aqueous samples. A consecutive DLLME in combination with fiber optic-linear array sensing spectrophotometry ( FO-LADS ) with charge-coupled device ( CCD ) sensor profiting from a micro-cell was used for this intent.2. Experimental2.1 Reagent and criterions The reagents used in the experiments were of analytical class: MB ( used as a cationic dye ) , sodium dodecyl sulphate ( SDS, employed as a representative anionic wetting agent ) , acetone as disperser dissolvers, trichloromethane as microextraction dissolver, NaOH, HNO3 ( 65 % ) , HCl ( 37 % ) , acetic acid, and Na ethanoate for doing buffer solution ) and obtained from Merck ( Darmstadt, Germany ) . Absolute ethyl alcohol ( & gt ; 99.6 % ) purchased from Bidestan company ( Qazvin, Iran ) . The needed measure of SDS was dissolved in pure H2O to do standard solution of 1000 mg L-1. The stock solutions of MB ( 3 A- 10-3 mol L-1 ) were prepared by fade outing appropriate sums in dual distilled H2O. All the plastic and glasswork were cleaned by soaking for 24 H in 10 % v/v HNO3. After cleansing, all containers were exhaustively rinsed three times with dual distilled H2O and twice with acetone prior to utilize. No any detergent was used to clean glasswork because it is hard to take from surfaces and causes high consequences. 2.2. Apparatus and Instrumentation apparatus The fiber optic-linear array sensing spectrophotometer was perched from Avantes ( Eerbeek, Netherlands ) . The light beam from the UV-Vis beginning ( Deuterium-Halogen ) was focused to the sample micro-cell ( Starna Scientific, Essex, England, Cat. NO. 16.40F-Q-10/Z15 ) . The spectrograph accepts the light beam transmitted through the optical fibre and disperses it via a fixed grate across the 2048 component CCD-linear array sensor. The instrumental parametric quantities are listed in Table 1. A Universal EBA 20 extractor equipped with an angle rotor ( Angle rotor for 8 A- 15 milliliter tubings, 6000 revolutions per minute, Cat. No. 2002 ) were obtained from Hettich ( Kirchlengern, Germany ) . An adjustable pipette ( 10-100 A µL ) was prepared from Brand ( Wertheim, Germany ) . All 0.1, 1.0 and 2.5 milliliter panpipes were prepared from Hamilton ( Reno, NV, USA ) . To clean out the micro-cell, avoid any memory consequence and better the repeatability of process, it was washed three times by about 2 milliliters of propanone between each analysis and dried with a watercourse of cold air by usage of a hair drier. 2.3. Mention process Hundred milliliter of sample was placed into a 250 milliliter dividing funnel and 10 milliliter of a 1 A- 10a?’3 mol L-1 MB solution and 15 milliliters trichloromethane were added. After agitating the mixture smartly for 1 min, the two stages were let to divide and chloroform bed taken for analysis. Each sample was extracted to boot two times utilizing 10 ml part of trichloromethane and optical density measurings were made at 650 nanometers in forepart of an external standardization prepared from SDS. Solutions in the scope between 0.1 and 0.5 milligrams La?’1 were extracted in the same manner than samples. 2.4 Recommended analytical process Into a series of screw cap glass trial tubing with conelike underside 5.0 milliliter of the standard SDS solutions at the concentration in the studied scope were pipetted out. Then 25 A µL of 3 A- 10-3 mol L-1 MB standard solution was added. Afterwards, 2.00 milliliter ethyl alcohol ( disperser dissolver ) incorporating 138 A µL trichloromethane ( microextraction dissolver ) was injected quickly into the sample solution utilizing a 2.50-mL syringe. This injection led to a cloudy solution, caused by the all right droplets of trichloromethane into the aqueous sample. The stage separation was accelerated by centrifugating at 5500 revolutions per minute for 3 min. After this measure the spread all right droplets of trichloromethane were settled at the underside of the aqueous solution in conelike trial tubing. Subsequent to this process, for evacuating the upper aqueous solution a long needle connected to 10-mL injection syringe was immersed down in to prove tubing and pulled the spe culator up till minute 200-300 A µL of aqueous stage remains at the top of organic bed. The volume of the settled organic stage was determined utilizing a 100-i? ­L microsyringe at 25  °C which was 65A ±2 A µL. Sixty micro-liter of this settled stage was removed by micropipette and introduced into micro-cell. The ordinary optical density of AS-MB ion-pair in trichloromethane was measured at the wavelength of 650.0 nanometers by agencies of FO-LADS.3. Result and treatmentIn order to obtain a high sensitiveness, the parametric quantities impacting the DLLME such as the type of the microextraction and the disperser dissolvers every bit good as their volume, concentration of MB, pH, and the microextraction clip were optimized. The enrichment factor ( EF ) was defined as the ratio of the analyte concentration in the settled stage to the initial analyte concentration in the aqueous sample. The analyte concentration in the settled stage was calculated from the standardization graph obtained by the conventional liquid-liquid extraction ( LLE ) /FO-LADS ( extraction conditions: 2.0 milliliters standard H2O sample in the concentration scope of 4.5 A- 10-4 – 1.5 A- 10-3 mol L-1 of MB and 1.5 – 5.0 mg L-1 SDS which extracted with 2.0 milliliters trichloromethane ) . 3.1. Chemical reaction of SDS and MB The equilibrium between SDS, MB and the distribution of SDS-MB ion-pair in H2O and trichloromethane has been qualitatively reported in the literature [ 14 ] . The AS dissolved in H2O are somewhat soluble in trichloromethane. On the other manus, MB dissolves good in both, trichloromethane and H2O, supplying a bluish colour solution in all the instances. When pure H2O is assorted with a chloroform solution of MB, the bluish colour is quickly transferred to the aqueous stage. 3.2. Consequence of ion-pair formation status parametric quantities The overall ion-pair formation status of SDS and MB is concentration of each, pH every bit good as clip needed. Our efforts were chiefly centered on optimising these parametric quantities under our microextraction conditions ( DLLME ) . In this survey the clip required for ion-pair formation were tested between 0 sec -10 min. The consequences, deducing from the ion-pair formation utilizing different reaction times, exhibited that the reaction clip has no any consequence on ion-pair formation efficiency and longer clip period did non better the reaction. In order to find the optimum pH for the ion-pair formation, several sample pH values were varied from 2.5 – 7.5 to prove the ion-pair formation of AS and MB in 5.0 mL H2O samples incorporating 0.04 mg L-1 SDS and extra sum of MB. The highest microextraction efficiency was achieved in the pH of studied scope and we found that in the alkalic solution MB it self would pull out into trichloromethane in absence of any MBAS. In optimisation processs no any buffer solution were used because after adding reagents the pH of solution become somewhat acidity in coveted scope. The influence of the MB concentration on the ion-pair formation/microextraction efficiency was performed in the scope of 0 – 2.1 A- 10-5 mol L-1 while the concentration of SDS was 0.04 mg L-1. During the fluctuation of this concentration the other experimental variables remained changeless. The consequences demonstrated that by increasing the MB concentration up to 1.5 A- 10-5 mol L-1 the microextraction efficiency increased and, so, no fluctuation were observed ( as depicted in Fig. 1 ) . Sing the fact that proposed method is additive up to 0.08 milligrams L-1, hence, the sum of 5 A- 10-5 mol L-1 MB was selected as consider adequate surplus sums. 3.3. Influence of the microextraction dissolver sort and volume The choices of an appropriate microextraction dissolver have a high importance function to acquire a high sensitiveness DLLME, so sort and volume of it were studied and optimized. Microextraction dissolver should hold particular features in DLLME ; it should hold really low solubility in H2O, extraction capableness of interested compounds, and much denseness than H2O. Chloroform and C tetrachloride are available as the most celebrated microextraction dissolvers in DLLME. During our primary surveies we found that C tetrachloride is non capable to pull out the ion-pair of SDS-MB at all. Furthermore, the recommended dissolver in the standard methods is trichloromethane ; hence, it was our extinguished pick. To look into the consequence of microextraction dissolver volume, experiments were performed by utilizing 2.00 mL ethyl alcohol incorporating different volumes of trichloromethane ( 138, 143, 148, 153, 158 and 163 i? ­L ) . By increasing the volume of trichloromethane from 138 to 163 A µL, the volume of the settled stage additions about from 65 to 90 A µL. Harmonizing to consequences ( Fig. 2 ) , optical density lessenings with increasing the volume of trichloromethane ; it is clear that by increasing the volume of trichloromethane the volume of the settled stage additions. Subsequently, at low volume of the microextraction dissolver high optical density or enrichment factor was obtained. 3.4. Influence of the disperser dissolver sort and volume In DLLME, choosing an appropriate disperser dissolver is of import, since disperser dissolver should be mixable with both microextraction dissolver and aqueous sample. For the interest of geting the most suited disperser dissolver, two sorts of instead safe disperser dissolvers: propanone and ethyl alcohol were studied. A series of sample solutions were studied by utilizing 2.00 milliliter of each disperser dissolver incorporating 138 A µL of trichloromethane and the enrichment factors were investigated. The consequences showed that ethyl alcohol showed much better efficiency than propanone ( enrichment factor of 75 and 17, severally ) . Less toxicity and the higher microextraction efficiency of ethyl alcohols make it a better pick. After taking ethanol as disperser dissolver, it is necessary to optimise the volume of it. The influence of the disperser dissolver ( ethanol ) volume on the microextraction efficiency was tested over the scope of 0.50 – 2.00 milliliter, but the fluctuation of the ethyl alcohol volume ( disperser dissolver ) caused alterations in the settled stage volume. Hence, it was impossible to see independently the influence of the ethyl alcohol volume on the microextraction efficiency in DLLME. To avoid this job and in order to achieve a changeless volume of the setteled stage, the ethyl alcohol and trichloromethane volumes were changed at the same time. The experimental conditions were fixed and included the usage of different ethanol volumes: 0.50, 1.00, 1.50, and 2.00 milliliter, incorporating 97, 102, 121, and 138 I?L of trichloromethane, severally. Under these conditions, the settled stage volume remained changeless ( 65 A ± 2 I?L ) . Fig. 3 shows the curves for optical density o f SDS-MB ion-pair versus the volume of ethyl alcohol. The optical density increased, when the ethanol volume increased from 0.50 to 2.00 milliliter of ethyl alcohol as disperser dissolver. Harmonizing to the consequences, a 2.00 milliliter ethyl alcohol was chosen as the optimal disperser dissolver volume. 3.5. Influence of the microextraction clip Microextraction clip ( interval clip between the injection of a mixture of disperser dissolver and microextraction dissolver, before get downing to centrifugate ) is of import factor that may be effects microextraction efficiency of analytes from aqueous stage to organic stage. The fluctuation for microextraction efficiency of SDS-MB as a map of microextraction clip was studied in the scope of 5 unsweet – 10 min. The ensuing informations, exposing that the microextraction clip has no important consequence on the microextraction efficiency for the mark compound. It was revealed that after the formation of the cloudy solution, the contact country between the microextraction dissolver and the aqueous stage was well big, defining why the extraction equilibrium could be established really fast. In this method the most time-consuming process was centrifugation of the sample solution in the microextraction process, which was about 3 min. Sing the fact this period of clip ( 3 min ) is for eight trial tubing ( microextraction vass ) , the clip required for managing one trial tubing is less than 25 seconds. 3.6. Analytic features of the method To measure the practical pertinence of the proposed DLLME/FO-LADS technique for finding of MBAS in H2O samples, several analytical public presentation features such as enrichment factor, one-dimensionality, bound of sensing ( LOD ) and repeatability were investigated under optimized conditions. The standardization curve was additive in the scope of 0.06 A- 10-1 – 0.8 A- 10-1 milligram La?’1 of SDS with a correlativity coefficient ( R ) of better than 0.99. The LOD, defined as CL =3 SB/m ( where CL, SB and m are the bound of sensing, standard divergence of the space and incline of the standardization graph, severally ) , was 0.02 A- 10-1 milligram La?’1. The repeatability of the proposed method expressed as comparative criterion divergences ( RSDs, n=7 ) were found to be 4.5 and 3.6 % for the concentration of 0.03 and 0.07 milligram La?’1, severally. The enrichment factor was found to be 75 for SDS. 3.7. Consequence of diverse ions and application to practical samples Any organic or inorganic compound that will organize a trichloromethane extractable ion-pair with MB will interfere by bring forthing high consequences. These positive intervention include organic sulfonates, carboxylates, phosphates, and phenols, every bit good as inorganic cyanates, chlorides, nitrates, and thiocyanates. On the other manus, any compound efficaciously viing with MB to organize an AS ion-pair will give negative consequences. These negative interventions cause by some aminoalkanes and have analytical significance in the instance of quaternate ammonium compounds. For pretreatment of MBAS in all Waterss and waste Waterss that contain meddlesome substances the undermentioned process is recommended by ASTM mention method. The selected sample is hydrolysed by boiling under partial reflux with hydrochloric acid. The residuary merchandises are neutralized to a controlled pH value, and reacted with 1-methylheptylamine. The resulting ion-pairs are extracted into a trichloromet hane stage and evaporated to dryness on a steam bath. The amine constituent of the ion-pair is removed by boiling in an aqueous alkaline media and the stray MBAS are so determined under the described mention process. Besides other research workers examined the consequence of assorted diverse ions on the finding of AS by similar method [ 14, 6 ] . In order to set up the cogency and pertinence of proposed method, it was applied to the finding of AS in several existent H2O samples ( mineral, pat, and good H2O samples ) by proposed method. For this intent, 5.0 milliliter of each sample was preconcentrated utilizing DLLME technique as described before ( pH was adjusted with acetic acid/sodium ethanoate buffer if necessary ) . In order to measure matrix consequence, the standard add-on method was applied for the finding of AS ( at spiking degrees of 0.02 and 0.05 mg L-1 ) in spiked existent samples which the comparative recoveries of analytes are mentioned in Table 2. The obtained consequences were compared with those obtained from spiked distilled H2O. In all instances, the spike recoveries confirm the dependability of the proposed method. The obtained comparative recoveries indicates that matrix does non act upon the microextraction efficiency in the mentioned samples ( no serious interventions ) , hence, there was non any duty t o take interventions. As it can be seen in table 3, the public presentation of proposed method shows distinguishable advantages over other methods with mention to try volume, extraction dissolver volume, RSDs, LODs and additive dynamic scopeDecisionsThis survey demonstrated that DLLME process with really pleasant and robust features for check of AS seems to offer possible campaigners for mention method, which utilizes really little sum of microextraction dissolver every bit good as its low cost. Furthermore, freshly DLLME process in combination with FO-LADS equipped with charge-coupled device ( CCD ) sensor profiting from a micro-cell demonstrated that LPME ( DLLME ) could be combine with spectrophotometer system despite of micro-level sample volume without any dilution and diminishing the sensitiveness. Analysis of several existent samples for AS content illustrated the truth, dependability, simpleness, dependability and bargain rate of method. It appears to be a time-saving techni que, chiefly for research labs executing analysis of a big figure of samples with a rapid coverage clip. Besides we suggest the pertinence of this method for supervising the biodegradation of AS.

A Recipe for Friendship

Friendships are not easy to come by. Like developing a new and unique recipe, friendships need time and patience. With the right technique and a little bit of effort, a good friendship can result in a satisfying and life-long relationship. Three key ingredients to a good friendship are loyalty, honesty and respect. Loyalty refers to constant support and allegiance. This can be as simple as one being loyal to one’s favourite sports team or one’s favourite coffee shop. However, loyalty can also play a more significant role. In order to demonstrate this, a loyal friend needs to be available for the most part, on an emotional level, but also be available on an intellectual and even physical level. Regardless of the situation, dependability is essential. For example, if one loses his job, and then his home, a loyal friend would help by loaning money, by taking him in to his home, or by helping him find a job for as long as it takes. Serious health issues test friendships, but loyalty remains priceless to an ailing individual. A loyal friend would not desert a dying individual, especially if he has a disease that is feared by many, like AIDS. A loyal friend will always have one’s back. Honesty is the act of being open and truthful. An honest friend can tell you when you have a bad haircut or when you have spinach in your teeth. This honesty might be awkward to take at first, but the nature of it is to save one from further embarrassment. Honesty fosters trust and must be earned. When trust is absent from a friendship, one cannot know when one is being told the truth. However, the honesty in a friendship must be sincere and fair; otherwise, the blunt truth can be hurtful. Believing and trusting an honest friend allows one to be open to new ideas. For example, friends who confront an alcoholic about his drinking in an intervention are doing so because they are sincerely concerned about his well-being. The truth might be difficult for the alcoholic to accept, but because a group of caring people are all trying to help, he might be more receptive of his situation and be more willing to change. This honesty can also preserve dignity. Respect for an individual refers to feelings of admiration and understanding, as a result of his or her qualities, abilities and achievements. However, respect, like honesty, also has to be earned and deserved. In most cases, it is not easily given. For example, we respect a fire fighter because of his courage and selflessness when he puts his own life in danger to save the lives of others. A neurosurgeon is respected for his surgical abilities and his years of academic achievements. Respect is warranted for his commitment towards his skill. Respect can also refer to recognizing one’s individuality and supporting one’s values, talents and interests. Individuality distinguishes one from another and it is important to accept and appreciate these differences. For example, we do not all share the same religion: one can be Catholic and one can be Atheist; we do not all share the same way of life: one can be gay and another straight; we do not all share the same morals: one can be pro-life and another pro-choice. One may not always agree with another’s beliefs, lifestyle or ethics, but it is important to acknowledge these distinctions to remain friends through mutual respect. Like a delicious home-cooked meal, a great friendship is not difficult to create. Dedication, trust and appreciation are key. With these quality ingredients, a dash of trial and error and the right amount of time, the combination of loyalty, honesty and respect can result in a worthwhile and enjoyable relationship.

Maya Angelou Essay

As a woman you are created with a special gift, it’s like little extra ingredients that all women have within them. The poem â€Å"Phenomenal Woman† by Maya Angelou, she speaks about the elegance of a woman, her inner being the way she glow without saying a word Maya expressed how men are amazed by her presence â€Å"men themselves have wondered what they see in me† (line 31-32). It’s hard to put your finger on it all women were born with the power. In the poem â€Å"Still I rise† by Maya Angelou she described the struggles of life trials and tribulations you face in society and the way people may judge you. As if she was writing about a woman â€Å"does my sassiness upset you? †She also wrote in another stanza â€Å"does my sexiness upset you? †She used this comparison to show she is a sexy woman who demands respect. Maya’s attitude in this poem is portraying a confident black African American woman. She is really laughing at men challenging them. They cannot stop her from rising above all expectation. This poem gives you not only inspiration encouragement to be fearless; to the end of it all you must believe you still rise above it all. The title gives a sense of entity and power. This masterpiece the poem â€Å"phenomenal woman† has also empowered women to get more in touch with their inner beauty. Maya describes in great detail the mystery of women and the behavior of men and their reaction. It shows women to not only love your-self but to embrace every aspect of your mind, body and soul. Maya show that sexuality isn’t only related to outer beauty, or by the way you dress it more about how you feel within your own skin . she shows you instead of hating your body love it from the crown of your head to the sole of your feet. In society today women enhances their body by doing plastic surgery to feel accepted. She feels inferior clearly stating that every part of a woman is beauty. In comparisons to â€Å"Phenomenal Woman† and â€Å"Still I Rise† both poems Maya speaks about not bowing to the â€Å"oppressor†. You can feel her compassion in every word in Phenomenal Woman â€Å"now you understand why my head’s not bowed† (lines 47). Still I Rise forth stanza â€Å"with head bowed and eyes lowered? †Within these lines she stresses that she will not conform to what society made her out to be, that she will soar above and beyond everyone expectations. The little gives a sense of entity and power. In conclusion these two poems have few similarities; Maya characterized the strength of an African American woman. By using powerful words she described the emotional aspect of inner beauty, standing proud professing no one will ever bring her down not by the color of her skin nor the fact of being a woman that there’s more within.

Privacy - Essay Example The government and other influential people have been very vocal in monitoring social networks, arguing that it helps the government understand how the public is receiving its policies and practices (Rennie). For instance, the UK government has responded to a law suit brought to court by a civil rights agent about privacy by saying that the government has a right to carry out what they call legal spying. (Queally, Para 1). Americans are also not left behind. According to Damon (Para 1), the US government is working with social media companies to plan for back-doors to help government spy in peoples social media accounts. This shows that governments are increasingly looking to spy on people’s live through social media. Although there may be an advantage for allowing the government to access personal information for investigation purposes, the problem is that this is prone to abuse. At the same time, the basic principle of justice and liberty require that the freedom of an indiv idual should not be scarified, not even when it is for the good of the public. In this regard, the government should look for alternative ways to do their investigation, and not interfere with the private lives of everybody else. No one should ever have the moral authority to interfere with people’s privacy, not even for the sake of national security. I believe that it is obscene for the government to look through people’s private information on social networks and phones because this goes against the constitutional right that guarantees privacy of individuals. Invading people’s privacy on the social networks and mobile phones by the government is a heinous practice that might result in illogical judgment about the social networks users. For example, most young people use the social media for dating and organizing youth oriented events. The dating language might look immoral to the government and parents, but the sender and

Emergence of Crime Prevention and Community Safety in the Context of t Essay

Emergence of Crime Prevention and Community Safety in the Context of the Crisis of Governance That Afflicted the UK during 1970 and 1980 - Essay Example Representations of crime and punishment offer, in varying measure, titillating glimpses of the seductions of deviance, moral boundary maintenance and an anxiety-arousing frisson of fear. It is further mentioned that election campaigns did not mention crime as an important issue until 1970 when Margaret Thatcher developed law and order into a major arena of ideological conflict. Thus it is evident that the UK had realized the importance of community safety and crime prevention during the late 1970’s which prompted the government to chalk out policies and framework for crime prevention. This paper examines the emergence of crime prevention and community safety in the context of the ‘crisis’ of governance that afflicted the United Kingdom during 1970 and 1980. Reiner (2000, p.81) mentioned that the increases in recorded crime levels were fuelled further after the mid-1970s by the consequences of the fundamental shift in the political economy represented by the return of free market economies and the deregulation of an increasingly globalized market. It is further mentioned that the consequences of crime and social cohesion are enormous because of the widening of social divisions, and growth fo social exclusions. As social exclusions, economic, insecurity and inequality grew; the motives and opportunities of crime multiplied and the restraining effects of both formal and informal social controls are eroded. Dingwall and Davenport (cited in Fennell, 1995, p. 21) mentioned that the United Kingdom today faces a problem of crime which could not possibly have been forecast at the end of the Second World War. It is further stated that crime rate increased from 50,000 reported crimes in 1950 to 1.6 million in 1970 which further increased to 2.5 mi llion in 1980. It is further stated in a comparative study by Biles that in the period between 1960 and 1979 the recorded crime rose by 177 percent in England and Wales (Fennel, 1995, p27).

Human Development - Essay Example Physical changes can mark significant stress reactions that can lead to a variety of negative behaviors. It is during this period where the desire to find independence from caregivers is strongly on their consciousness, and the level of stress will either increase or decrease in relation to how their parental figures handle this new need for independence. More controlling families could lead the child to develop depressive symptoms while a liberating household might give them the freedoms they demand, therefore having minimal stress and stress reactions. Environment and the level of control placed over the youth during adolescence will determine whether or not this is a period of stress and storm. A highly controlling household acts as an impediment to perceived achievement, which is considered a strong factor in males that can lead to stronger emotional outbursts or negative stress response (Kort-Butler, 2009). In terms of finding self-identity, it is often the opinion of peers that dictate how a person views themselves and they consider the thoughts of people in various reference groups when molding their self-concept. Media can play a big part in the child’s viewpoint, such as with young females comparing themselves to beauty ideologies represented in many television commercials, and then finding dissatisfaction for not being able to attain these physical traits. Even though this is a distorted view, the outcomes on personal adolescent stress that is caused by reference groups can be quite negative. It is common for adolescents to go through what is referred to as a moratorium, where they have non-conformist attitudes and a strong rebellion toward parents, with peer groups considering their behaviors to be intense and outside of the social norm (Weiten & Lloyd, 2005). Youths that fit this profile often will not commit to parental moral values, or sometimes those of peers, and they find themselves (at least

Porters Five Forces to Analyze the Competitive Environment in which Essay

Porters Five Forces to Analyze the Competitive Environment in which Ryanair operates Bargaining Power of Suppliers - Essay Example The customers of Ryanair are putting on them a lot of collective pressure so that they can lower the travel expenses and improve the quality of their airline services. The customers associated with Ryanair are enjoying a higher bargaining power since switching to other airlines with better services is very easy with little or no costs. In the case of Ryanair, the substitutes for their transport systems include railways, sea transport, and road transport and any strategy by them poses a threat to Ryanair profitability. However, Ryanair is still able to operate at a lower cost, leading to lower cost of services that attract more customers. The threat of new entrants in this industry is relatively low due to high costs involved in the initial stages of the business set up that many cannot afford. Economics of scale can only be enjoyed by big players like Ryanair and this makes other possible investors be scared away (O’Cuilleannain, Falle, Sobokta, Kleinert, Chassart, Farrell, 2004). There is also difficulty in gaining access to distribution channels that poses a barrier to new entrants. Since the airline industry is highly fragmented, competition is very high leading to low returns. In order to survive, Ryanair is constantly coming up with unique business models in order to outweigh their competitors and make reasonable profits. Ryanair is luck since it is based in Europe whereby European Union is a complete stable political region that provides a good environment for business to thrive. The integration of the European Union has provided an opportunity for this airline industry to expand its operations very swiftly without hurdles (Muller, 2011). The operations of Ryanair are also affected by the OPEC since its an organization that determines the fuel prices that Ryanair operates on.

Managing User Accounts In Linux Essay Example for Free

Managing User Accounts In Linux Essay Linuxs most notable advantage over other operating systems such as Windows and Mac is security and in order for a user to modify critical components of the system, such as user accounts, is to have access rights of a ROOT. The root is at the top level of Linuxs user hierarchy and has all the privileges to access all resources. To login as root, a user must use the command su username. After pressing the ENTER key, the system will prompt the user to type in the corresponding password. After entering the correct password, the user will inherit full access privileges including the right to modify other users account information. Attempting to enter the correct password will deny the user from inheriting the roots privileges. # su [screenshot] Let us now attempt to create a new user called bozo. But first, let us check if that username is not yet taken. # id bozo [screenshot] Since username bozo is still available we can now create his user account. # useradd bozo -d /home/bozo -u 600 We have just created a username called bozo and makes his default folder under /home/bozo and gave him the UID of 600. by the way, UIDs are unique identifiers of users. Users can be a representation of both human users and services running in the Linux system. UIDs are used by Linux in relation to his password and privilege information stored in the /etc/passwd, /etc/shadow and /etc/group. One of the very first thing Linux does when creating a new user is to copy the files from the skeleton folder, which contains whatever files the admin wants to give to new users, into the newly created users folder. Now, let us try to take a look at those files by displaying a detailed listing of files including hidden ones. # ls –la /home/skel/ So far so good. Now let us try creating another user and call her bozoette. # useradd bozo -d /home/bozo -u 600 We had an error. As stated earlier, UIDs are unique. Since we attempted to create a user and assigned the same UID with bozo, the system denied our request. But what if we do want give bozoete the UID #600? One of the many ways to do it is to first change bozos UID, say 601 and then create bozoettes user account using the newly-vacant UID of 600. Change bozos UID from 600 to 601. # id bozo # usermod -u 601 bozo # id bozo Then create bozoettes new account with UID 600. # useradd bozoette -d /home/bozoette -u 600 Now we have two new users bozo(uid:601) and bozoette(uid:600) with user directories /home/bozo and /home/bozoette, respectively. Note that user accounts remain inactive until a password is assigned to them. Let us now activate the two new user accounts by assigning passwords to them. # passwd bozo # passwd bozoette Users bozo and bozoette are now active and users can now login to the system using the correct username and password combinations for the accounts.

Louis MacNeices and Thom Guns poems Essay Example for Free

Louis MacNeices and Thom Guns poems Essay Louis MacNeices and Thom Guns poems use the first voice to look at birth through babies eyes. They help us see that babies, unborn or newborn, are living but powerless beings. They can think and feel but cannot make decisions or changes in their lives. MacNeices piece is burdened with desperate pleas from the womb for a chance to live while Gunns poem takes on a lighter tone towards a newborns protest to leaving the comfortable and familiar womb. Written in the form of a prayer, the Prayer Before Birth addresses God as its audience but the poets intention is really to decry the horrors of abortion to the reader. The poem takes on a troubled tone of one who is facing death sentence. The effects of its tone are made stronger through the use of the first person in the impotent unborn baby to dramatize the fact that it is alive and not given a choice for its life. Each stanza repeats the fact that it has yet live. This set the reader into the speakers deepest burden as it reveals its concerns. The poem also uses images associated with pains and fears the speaker faces to communicate its tone of deep depression. The first stanza shows us a childs nightmare of bat, rat and ghoul; followed by equipment of torture such as walls, racks and drugs; then criminal acts of treason and murder; men in authority as in old men, bureaucrats and manwho thinks he is God and finally the vivid description of the brutal act and the detachment of the speaker from its source of humanity. All these depressive images are interrupted only in the third stanza, with a sense of longing and in warmer tone, to experience life from childhood (being dandle) to death (being guided by a white light). It brings images of nature and life and all that we take for granted. Even the poems structure supports the tone. The long sentences and heavy-sounding words (dragoon, dissipate and bloodsucking) communicate a heavily laden heart. The poem moves slowly with increasing length at each stanza and that tells of a deepening sense of hopelessness. The sixth stanza is very short as if to communicate the end of the hope. The last stanzas lines shorten with each subsequent plea as if to signify the shortening time  left. The poet chooses words that support the deeply burdened tone and evoke the readers emotional response. This is especially so when an innocent unborn has been subjected various agents of abortion in the form of creatures of the night (bat, rat and ghoul), equipment of torture (walls, racks and blood-baths), criminal acts (treasons and murder) and unloving human (lovers, beggars and bureaucrats). They communicate uncaring, cold and relentless in achieving their ends without regard to the subject. Many rarely used heavy-sounding and multi-syllabus words add to the ominous mood as they dragoon, dissipate and engendered the speaker. And then the word thistledown also helps add the finality of the act as we picture the foetus as unattached weed just go directionless and lifeless (hither and thither) to be [spilled] like water into the drain. The use of the word me gives a picture of helplessness to be subjected to other peoples direction (think me, beyond me, live me, curse me, lecture me and hector me). The sum effect of the dramatic play of words is designed to create the dark, troubled mood of one facing death sentence and to draw a response from the reader. On the other hand, Gunn also uses the first voice but he gives the protesting baby a less intense tone. His intention is to explain the babys first cry and he thinks that it is from its reluctance to leave an environment of security and warmth for a strange and cold world. The poem carries an angry tone of complains (Things were different inside)and warm tone of memories (The perfect comfort of her inside). Like the previous poem, the effect of its tone is made stronger through the use of the first person who shares its experience first hand. Yet unlike the first poem, the tone it carries is not as overwhelming as to evoke a respond from the reader for it hints that it is only temporal (I may forget). Gunns poem also uses images but those of contrasting scenes to communicate its objection to the changes. One can hear the warm and longing tone as the baby thinks of the snug and secure jolly and padded and [the] perfect comfort of her inside. Otherwise, the poem moves in exasperation as it compares the warm and wet and black womb with a rain of blood and the discomfort of the lighted outside world, the exposed and spacious rustling bed and the changes that comes when all time roars. Like MacNeices poem, it also communicates a helpless baby in the midst of the situation it cannot change as it lies raging, small, and red. And it may continue to rage till it forgets for it has no choice to the matter of whether it wants to be born. Gunns poem is designed to support the tone of protest through its fast-paced, easy-to-read rhythm and rhyme and its short and even sentences. These, as compared with Prayer before birth, give the effect of a less forceful albeit angry tone. Its pace slow down a little in the last two stanzas (with longer vowels sleep, soon, womb and room) as the child gets tired and slips into dreams of the familiar surrounding again. The poem keeps the lighter tone and moves with ease through informal and conversational language. Many of the words chosen in this poem refers to tangible objects as in womb, bed and room. The tone is also supported by choosing single-syllabi action words like fall, ride, tuck and lie. All those action words imply how quickly everything happens between birth and the babys sleep. Many words also indicate the drastic differences the baby has to endure at birth e.g. from private to a shared environment; from the warm and wet and black womb to a lighted room; and from padded and jolly to rustling. All these imply changes the baby needs to adjust to. But they are all temporal shock and the protest will not last even though the newborn may fight it But I wont forget that I regret. And eventually, all that is left of the memory of the womb may exist only in the babys dream. Both poems revolve around the subject birth and give thought to life. The main difference is that MacNeices poem is meant to evoke a response or perhaps provoke the reader to action while Gunns poem only wants to share a response of a baby at birth.

Gulmay D3300 X-ray Therapy Machine System

Gulmay D3300 X-ray Therapy Machine System Gulmay D3300 x-ray therapy machine system from Gulmay Medical Ltd. Introduction  ­Ã‚ ­Ã‚ ­Ã‚ ­Ã‚ ­Ã‚ ­Ã‚ ­Ã‚ ­Ã‚ ­Ã‚ ­Ã‚ ­Ã‚ ­Ã‚ ­Ã‚ ­Ã‚ ­Kilovoltage unit was one of the first external beam therapy used in a radiotherapy department. Despite its popularity then, departments opt into using a megavoltage machine due to its versatility in treatment. The uses kilovoltage therapy, especially superficial x-ray therapy remains widely important in treating certain cancer patients. Gulmay Medical Ltd is one of the world’s leading manufacturers in Kilovoltage x-ray therapy equipment’s. One of its latest accomplishments was building Gulmay D3300, a combined superficial and orthovoltage unit, beam energy ranging from 20-400kv. In this essay, I will be describing the physical aspects of a Gulmay generator and x-ray tube used within this machine, their role in the production of x-ray as well as its cooling mechanism. I will be discussing the uses of having such combined units, the benefits and the complications it will cause to both the NHS, departments and the patients as well as the advantages and disadvantages of using cut out lead shielding within a treatment. Description The generator aims to magnify the initial input voltage to a substantial amount, enough to potentiate x-rays with a certain Half Value layer (Flinton, 2009). The CP225 generator which can be attached to the D3300, is powered by 3200W-4500w and has the capacity to generate voltage from 220V to 20-225KV (Gulmay Medical Ltd, 2014). Connected to the generator is the X-ray tube, via cables joined to both the anode and the cathode (figure one). The tubes are in a unipolar arrangement whereby the negative potential from the generator is fed into the cathode and the anode is maintained at a ground potential (Earth). (Flinton, 2009) Figure one: A map of the equipment’s inside a Gulmay Superficial x-ray therapy machine (Gulmay Medical Ltd, 2014). The CP225 generator is able to attach to a high power x-ray tube, 225/11, which can take up to 225V, ideally suited for its generator (Gulmay Medical Ltd., 2014). The tube is covered in a metal ceramic material and compromises on a ceiling support or on a floor stand. The mounting requires a manual force to move in the three axes -transverse, longitudinal and vertical, as well as rotational and tilt movement of the tube (Flinton, 2009). The cathode assembly, within the tube is held by a ceramic insulator aimed to insulate it from the metal housing of the tube and consists of a single tungsten filament. Compared to the cathode, the anode is structurally dissimilar, as shown in figure two. Made out of copper, the anode is either wielded onto the metal tube envelope or a ceramic insulator is sandwiched between them. The anode has extensions known as an integral hood and located on the side of the hood is a desired x-ray exit known as a beryllium window, which has a filtration of 0.8mm Be. The tube is enclosed within a vacuum to ensure the electrons do not interact with other particles, slowing down the production of pure x-rays (Flinton, 2009). Figure two: The internal structure of an x-ray tube (Flinton, 2009, p.153) As the heat builds up within the tube, it is removed from the target through conduction of the Copper anode acting as a heat sink due to its large size. To ensure efficient and rapid heat conduction, a cooling system is attached to the tube which ensures a high temperature difference away from the target (Figure one). Because the x-ray tube is unipolar, it is safe to ensure the flowing cooling medium within the cooling system is water, (Gulmay Medical Ltd., 2014) and therefore cost effective to implement. Since water is a conductor of heat, it is constantly replaced by new cool water once it has heated up. When the electrical current passes through from the generator to the tube via the cable, it reaches the cathode assembly heating up the tungsten filament. The filament then emits electrons in a process known as thermionic emission. The filament develops into a focussing cup containing a static negative charge stopping the electrons from scattering and to coerce them together to ensure the electrons aim at a small sectional area of the anode (Flinton, 2009). The cathode becomes highly negatively polarised that the grouped electrons are fired and strike a target within the anode, made from tungsten. The electrons begin to decelerate and release energy creating x-rays and heat (Xstrahl, 2014). The integral hood absorbs any unwanted electrons and prevents secondary x-rays from forming (extra focal radiation), whilst the beryllium window allows the primary x-rays to leave the tube (Flinton, 2009). Discussion Evan et al. (2001) states that by having a combined superficial and orthovoltage unit rather than two units, it will save half the money to facilitate separate shielded treatment rooms. There will also be a reduction in capital costs, spares, precautionary maintenance and quality control resources. However, by having a combined unit, the beam characteristics should be compromised as they are all necessitated by the use of a single X-ray tube to generate a beam as well as if the machine was to break down, the department may be at a loss of all kilovoltage treatment capacity. By having a low energy treatment, it is simple to treat superficial lesions. The low energy components of Gulmay d3300 allow many skin lesions to be treated up to 5mm deep, and by having a medium energy component it will allow treatments of skin lesions up to 2cm deep to be treated (Klevenhagen and Thwaites , 1993, and Glees, J.P and Wolstenholme, V., 2006). The aim of superficial x-ray therapy is to apply the dose superficially, maintaining the lack of skin sparing in order for the treatment to be successful. The fall in dose with depth is slower for x-rays than electron, thus the dose is below the treatment site is higher, being most effective in superficial treatment. Majority of the internal anatomical sites are not significantly affected by the radiation, The drawbacks to this is if treating an area neighbouring structures in which contain poor blood supply and are at risk of radiation damage such as cartilages, then it would be beneficial to use an electron beam due to the rapi d fall-off (Griffiths, 1994). When using an orthovoltage machine, the aim is to treat deep seated tumours at a close depth to the skin by applying a great amount of dose to the surface of the patient before it reaches the tumour site. The lack of skin sparing can result into skin damage caused on a patient (Griffiths, 1994). Patients can suffer acute reactions and late reactions. When patients begin their treatment, the acute reaction will follow in stages. During the first treatment, the patient may feel warmth in the area being treated; this is followed by the reddening of the skin, known as erythema, which can appear from a dose level of 1GY. As the dose escalates, the treated area will become itchy, sunburn like red, and is prone to injuries. Around 14 days, the hairs in the treated areas may fall out in a process known as epilation. By the time patients get to this stage finish their treatment course. This is due to the lengthy fractionations of treatment; the degree of reactions becomes less severe. Once the treatment stops, skin will begin to heal and becomes tanned. However, patients that go through a long treatment will experience reactions at a greater degree. The next stage in the skin reaction is dry desquamation, the peeling of the skin in dry flakes. Furthering this treatment, the skin then becomes dark red or purplish and fluid will start to build up underneath causing oedema, which is tender to touch. It is broken down and blisters start to form, the fluid begins to seep out of the skin. Patients treatment is then at a halt due to the severity of the reaction. Within an orthovoltage machine, by giving a high dose, the stem cell pool within the skin will be destroyed and area of ulceration will remain lasting within the treated area of the patient (Lochhead, 1983, p. 107-108). Late reactions are dependent on the beam energy and the dosage level. ‘The beam energy determines the part of the skin that is affected by the radiation.’(Lochhead, 1983, p. 107-108). By using low beam energy of up to 300kv, the germinal or basal layer of the skin demonstrates the most change to the skin. Activity is lost within the cells and the skin becomes thin. Once the skin becomes damaged it will take a long time to heal. Places where the hair has epilated may become permanent due to the destruction of the hair follicles. Sweat glands are destroyed and superficial blood vessels deteriorate. Other blood vessels nearby would enlarge to compensate the damaged blood vessels, and patients may begin to form Telangiectasis, a condition whereby the patients skin becomes pale and the red blood vessels enlarge. An injury to the patient may cause a necrosis of the skin. According to Griffiths et al. (1994, p.35) it was thought that by creating multifeilds across the tumour, patients’ skin reactions may subside. However this had caused a high integral dose on the patient as well as sore skin. Now it is often more advantageous to have a megavoltage machine treating these tumours due to the skin sparing affect it provides for the patient and the orthovoltage is progressing to become outdated. One of the main forms of shielding in a superficial and orthovoltage machine is the use of a lead cut out. A lead cut out is made to define the treatment area as well as shielding normal healthy tissue from the radiation beam. This is used in conjunction with an applicator attached to the machine collimator. It also provides direction and localisation of the beam. For the face and areas close to the eye a specific lead mask is produced, to avoid radiation to critical structures nearby (Mills et al., 2012). The study of Medvedevas et al (2001) concludes that the application of lead shielding attenuates the dose received to normal tissue significantly. However, according to Flinton (2009) the drawbacks in using lead shielding is the elevation in dose on the beam side of the lead caused by the interactions that arise in the lead shielding behind the target volume, as a result from the high backscatter component at these energies. The build up to full back scatter is most rapid in small fields, more so in low energy beams. For small fields such as the eye, this is a problem. Mills et al (2012). At the point when treating the eye, shielding made from either tungsten or lead is inserted to protect the lens. ‘The problem encountered with eye shields is the contribution from scatter which reaches into the region under the shield from the surrounding field.’(Mills et al., 2012, p. 125). A way to resolve this was by applying tissue equivalent material, i.e. wax, around the shield to absorb the scatter avoiding this problem.

When considering the numerous types of interactions between humans and computers that occur on a daily basis, from simple data entry and clerical work to high level programming and graphic design, they all require people to physically input information into the machine and receive some sort of visual or audio output. This, in fact is the primary goal when referring to input and output devices; to transfer information from a person’s mind into the computer and to then have the computer relay the results of said input. The difficulty in the transferring of information from the human brain into a computer lies essentially within the input device. The majority of input devices which are commonly in use today are simply not substantial enough to allow users to convey information to a computer at a sufficient rate. This problem has lead to the exploration and development of numerous new input devices. This paper will speak to these new input devices and how they, along with their corresponding output device, will allow the average computer user to decrease the latency between the human mind and the computer. With current technologies employed by the average computer user, the most common method for transmitting information from a human into a computer is through two simple devices, the keyboard and the mouse. These specific input methods, while convenient and nearly universal, are limited by the speed at which a human can operate them with their hands. To use typing as an example, it is reasonable to assume that anyone who works in the field of computer science or any of the various related industries knows how to use a keyboard to enter text into a computer. However this method of information transfer has its upper limits. Assumi... ...ices still suffer from the same limitations as the keyboard, namely that they are both limited by the speed and dexterity of the human hands. The computer mouse operates in a two dimensional world, generally manipulating two dimensional data such as text editors, internet browsers, and email applications. Nonetheless, there is a large portion of the computer industry which operates with various three dimensional applications. It is with these types of applications that gestural interaction becomes of greater value. Once such method of interaction that has received considerable attention in recent years is 3D spatial interaction where users’ motions are tracked in some way so as to determine their 3D pose (e.g., position and orientation) in space over time. This tracking can be done with sensors users wear or hold in their hands or unobtrusively with a camera.

A Farewell to Arms Essay: Inevitability of Death Revealed

Inevitability of Death Revealed in A Farewell To Arms      Ã‚   Ernest Hemingway has been greatly criticized for a supposed hatred of women that some feel is evident in his writings. One of the primary books that critics believe shows this misogynistic attitude is A Farewell To Arms. It is counterproductive to interpret the book using such a narrow focus because the author is dealing with much more profound themes. Hemingway is not concerned with the theme of gender equality, but rather with the greater themes of the inherent struggle of life and the inevitability of death.    The first images of struggle and death are seen in chapter 9 when Frederic is wounded. Up to this point in the story Hemingway had portrayed a very serene, pastoral setting and existence for the characters. It is here, though, that this comes crashing down. Hemingway is showing the horrors of war. War is not a glorious and colorful event; it is a dirty and base thing. This is the first hint that the romantic notions Frederic clings to might prove false. There is suggestion here that human existence is fairly tragic.    Hemingway shows many deaths as a result of the war. Passini, Rinaldi (who it is inferred died of syphilis), nameless officers, a sergeant, Aymo, and many others are casualties of the insane war. Their deaths are shown as casual, random events in the life of Frederic. Throughout the entire book Frederic seems to be trying to escape this death that is all around him and retreat once more to the serene existence he enjoys at the beginning of the book. This sets up what I believe to be the theme of the book: struggle is inherent in life and death is inevitable.    Another representative of death is Count Greffi towards the e... ...ainst Hemingway that charges he is a woman hater. Hemingway does not idealize Catherine out of some deep hatred of women. He does not subordinate her to show male dominance. In fact, I believe that Catherine is a minor factor in this book and is more of a tool used for thematic purposes. Hemingway uses her to show Frederic's inability to escape death. To use the ant metaphor (327-328), we are all ants on a log unknowingly running into the fire. And just when the log is tipped so we are away from the flames, just when we think that we are safe, someone tips us back in the fire and we die. Hemingway is showing that man's frantic struggles and his scurrying about are futile, we all die in the end. Also, as much as we may try, we cannot keep death out of our lives.    Works Cited Hemingway, Ernest A Farewell To Arms. Scribner Paperback Fiction: NY, 1995.   

Post-Traumatic Stress Disorder and Veterans Essay -- PTSD in Military

Posttraumatic Stress Disorder (commonly known as PTSD) is an important issue associated with military soldiers. The primary focus of this paper will be on the causes of PTSD and the effects it has on returning soldiers from the wars in Iraq and Afghanistan. I will attempt to elaborate on the soldiers' experiences through my own experiences in combat both in Iraq and Afghanistan. I will explain what PTSD is, look at the history of PTSD, how people get it, and differences of PTSD between men and women, and treatment options. As far back in history as we can go, humans have been in a fight for survival. There have been battles with gigantic mammoths, soldiers charging the front line with swords drawn or teachers witnessing neighbors being gassed to death. These are all significantly stressful situations that can lead to PTSD and have been around for centuries. For as long as there have been humans fighting there has been PTSD, it just wasn’t a term yet. During the Civil war, problems with PTSD became so severe that the first ever Military Hospital for the insane was established in 1863 (Bentley). Before that, since Military officials didn’t know what to do, or what was wrong with these physically able men they just threw them on the street or sent them home. With so many insane soldiers walking around, it was the public who insisted that something be done to help these soldiers and keep them off the street (Bentley). It wasn’t until 1905 during WWI that there was a link made between the mental collapse and the stresses of war(Bentley). There were so many cases of PTSD at first that officials believed it was caused by the concussion of shells on the brain, so they called it â€Å"shell shock†. It was the Russians who f... ...t.

Commentary: Moon Tiger, 1987, by Penelope Lively

-Make notes on health -Make case study notes on hydrology and coasts -Do past questions on coasts & hydrology -Do poem essay -Plan kinder transport essay Commentary: Moon Tiger, 1987, by Penelope Lively This monologue depicts the thoughts of an elderly woman who is dying in a hospital. She gives us a her views and description of language which shows us the importance it holds in her life. She talks about the history of language saying ‘we open our mouths and out flow words whose ancestries we do not even know. ’ This shows that she cares greatly about words and their origin and it is important to her that more people care about it as well.The rhyming of ‘flow’ and ‘know’, may also have a humorous effect as it suggests that she is playing with the words. She also uses imagery to describe what words are like saying they ‘blow with the wind, hibernate, reawaken, shelter parasitic on the most unlikely hosts, survive and survive and surviveâ₠¬â„¢. She personifies language, comparing it to an animal or a plant that does not die but rejuvinates. This indicates how strongly she feels about language. She describes it as being immortal as it will never end. This might give an insight as to how she may feel about dying.She may want to survive her illness, hence the repetition of ‘survive’. The repetition of this word draws emphasis to it. She may hope to live on through her words. She continues to compare language, using metaphors, to other aspects of nature such as when she says ‘it was like grains of sand on the shore, the leaves on the great ash outside my bedroom window, immeasurable and unconquerable’. The use of the similies gives us an image of how vast and large language is as the decription depicts how timeless and endless words are.She also makes use of the strong adjectives, ‘immeasurable’ and ‘unconquerable’ and how much power language holds to her and maybe how she feels when she uses it. She depicts people as ‘walking lexicons’, objectifying them. This may indicate that she cares more about language than people and suggests that she believes that words have a significant effect on people’s lives and shows the importance of it to her. Through this we get a good sense of her character. We see that she is quite a proud person. We get flashbacks of her life as a child when she is ‘gloating over Gordon who ould not spell ANTIDISESTABLISHMENTARIANISM, the longest word in the dictionary’. This shows how proud she is of her knowledge of language as she holds it over others. She also puts emphasis on the word which tells us more about how confident she is on the subject. She collected names of stars and plants such as ‘Arcturus’, ‘Betelgeuse’ and ‘toadflax’. These words are not very common to come across and may also suggest how smug she is about how much she knows on language . Similarly, it may show how superior she feels knowing this information. It is her hobby to collect words which shows the importance of it in her life.Another flashback we get of her is when she is taking care of her daughter as a child. These flashbacks give us a sense of her backstory and her character. She admits to herself that she is not a good mother and uses the word ‘repellent’ to describe her feelings towards children. This is quite a strong negative word to use towards children as most people love children and wouldn’t describe them this way. It is also a great contrast to the way she talks about words and language. She talks about ‘the excitement of language’ and how it is ‘immeasurable’ and ‘inconquerable’.She clearly doesn’t feel the same way about children as she describes them as ‘boring’ and ‘distracting’. She gets impatient with her young daughter, correcting ‘the inan ities’, who is barely able to pronounce words correctly. She uses plosives, saying , ‘There are no such things as bow-wows and gee-gees’. This shows that she is gettig irked by a minor problem with language and shows her intolerance. It also shows that she is a stern person. We are made to feel sympathetic for her at the beginning of the extract as she says, ‘Today language abandonned me’.This show how stranded she feels without being able to recall as much about language as she used to. She refers to it how she would refer to a friend that had left her. She continues on ‘staring into a void’, whih emphasises how empty and lonely she feels without it. She starts to list words, ‘vase, cupoard, window, cutain’, which also highlights the panic she feels when she is not able to remember simple words. Language has been her strong suit through life, #her hobby and her friend and now it has ‘abandonned’ her, she feels helpless.

History of the Werewolf

The werewolf is a myth that has been around since the ancient Greeks and is still prevalent in today’s culture. Some websites say that the origins of werewolf’s are in the territory of the Fox tribe today known as Wisconsin. People who have seen a werewolf have described it as a tall, greyish white beast that stands on its hind legs. Some legends say that werewolf’s are the seventh child born, others say they are men that have gone on angry rampages killing entire villages in wolf hides, others say the full moon causes men to change into wolves and become violent.Before researching this paper I had questions about where the term werewolf may have originated. I also pondered about when the first recorded sightings may have been for werewolves or how to become a werewolf. During my research I found out that the prefix â€Å"wer† is Saxon for man, so it means man wolf. It is said that the first sighting of a werewolf was recorded in 1550 B. C. near Arcadia. T he story is about King Lycaon of Arcadia who supposedly gave an offering of human flesh to the God Zeus. As a punishment Zeus turned him into a wolf.In Native American mythology it is said that Wisakachek produced the first werewolf. I found out that people can become werewolves through a virus called Lupine Parvovirus or LPV. This can only be transmitted by a wolf bite. Usually a virus takes over a cell and uses it as a factory or host for producing proteins. LPV is different from most viruses in that sense because it transforms the host organism instead of destroying it. The story starts with Wisakachek meeting two boys out hunting for their village.He gave the hunters the ability to shape-shift into wolves in order to catch deer, but only for catching deer not to kill humans. The one boy named Matchitehew got into a scrum with another boy from the village. In his anger he turned into a wolf and killed the boy. The two hunters Keme and Matchitehew were kicked out of the village. W isakachek became furious and casted a spell on Matchitehew that turned him into a mindless wolf every night. Keme left knowing that Matchitehew would not be able to control himself.Matchitehew became known as the father of werewolves. In present times werewolves have more influence than ever. From dominating the screen to books the legend of the werewolf lives on. Movies and books such as Twilight have deep mythical roots. With the books and movies grossing well over three billion dollars we could deduce that werewolves play a role in the world’s economy. Another effect werewolves have on society is they are vicious man eating beasts that may hurt little children.

A Life in the Day of Juan Ponce Enrile

A life in the day of Juan Ponce Enrile By Bibeth Orteza, Philippine Daily Inquirer 26 February 2012 Source: http://newsinfo. inquirer. net/151905/a-life-in-the-day-of-juan-ponce-enrile (Editor’s Note: The author set out to observe a day in the life of her husband’s uncle, Senate President Juan Ponce Enrile, as he presides over what is one of the most important trials in the country’s history—the impeachment of the Supreme Court Chief Justice. Graciously welcomed by her subject into his home and allowed to tag along to the trial, she came away with much more than just the details of a daily routine.The star of the moment obliged her with a sometimes tearful recollection of his life, enough material perhaps for a scriptwriter like the author and a director like her husband Carlitos Siguion-Reyna to turn into a riveting movie. ) 8:15 a. m. THE MAN of the house is still in his bedroom. Sally Moneda, his cook and personal assistant of 26 years, reminds his clos e-in aide, Julius Gumban, not to take away the newspaper as â€Å"he has not read Bernas [constitutionalist Fr. Joaquin Bernas, SJ, who writes an opinion column in the Inquirer–Ed]. The books under the stairs include the New King James Version of the Holy Bible (quick reference edition); â€Å"Spiritual Politics† by Gordon McLaughlin and Gordon Davidson; â€Å"His Excellency, George Washington† by Joseph J. Ellis; â€Å"1,000 Places to See Before You Die† by Patricia Schultz; and â€Å"The Oxford Companion to Politics of the World† by Joel Krieger. Also â€Å"Presidential Plunder, the Quest for the Marcos Hidden Wealth† and â€Å"Struggle and Hope,† both by Jovito R. Salonga, right next to five books written by Ferdinand E.Marcos during his martial law years. On the flyleaf of â€Å"The Marcos Years,† the former president had handwritten a dedication to the man who would remain his secretary of national defense until 1986 when a People’s Power revolt, aided and abetted by the latter, toppled his dictatorship. â€Å"Sept. 10, 1972, on the eve of my birthday To Johnny, who has contributed to the achievements of the Marcos years in a large way. † 8:25 a. m. Bing Rosales, sent to study reflexology for two years after showing aptitude for the therapy, leads her boss down the stairs. He’s good to us, so we pray that nothing bad happens to him,† she says. â€Å"Good morning, good morning! † exclaims Juan Ponce Enrile. First, his blood pressure is checked. It is normal at 126/60, from a high of 190/90 the previous afternoon. It shoots up every now and then so he has to take maintenance medication. He really should sleep early but just the other day, he didn’t hit the sack until 4 a. m. , he says. His bedtime varies, depending on the amount of reading he feels he has to do because, he says, he has to study and weigh things as well as he can. You see, I am not the court. Th e Senate is the court,† he says. â€Å"I sign the subpoenas, but I need the permission of the court. There is equal weight among the rights of the respondents, the policy of government, the impact of the decision on the public, on the business sector, on everybody. (If we) block disclosures on the basis of loyalties, the public will think we are covering up. People don’t really know the law as much as they do their doubts and their suspicions. 8:30 a. m. Breakfast is a sausage with a dab of mustard.Sometimes it’s a bowl of oatmeal, eaten with inihaw na pusit (dried squid), or rice with scrambled eggs and tuyo (dried fish). Some mornings it is pan de sal (roll) with cheese. Enrile is told this paper has referred to him and defense counsel Serafin Cuevas as the â€Å"superstars† of the ongoing trial. He shrugs, â€Å"I don’t know what that infers. † He likes to pore over his cases alone, he says, and tests the validity of the opinions of other s against his own study of all the issues involved. â€Å"I make my own trial brief,† he adds.In the years when he was practicing law, he says, he would first check a case for any violations against the Constitution, and then study the laws that could apply, given the facts, the pleading or the complaint. â€Å"I was fortunate to have met brilliant minds in and out of court,† he recalls, such as Vicente Francisco, Jose W. Diokno, Alberto Jamil, Rod Jalandoni, Claudio Teehankee, among others. At 88, he can still name his professors at the University of the Philippines College of Law where he received his law degree in 1953. Jose Espiritu for corporation law, Emiliano Navarro for criminal law, Enrique Fernando for constitutional law, Peping Campos for negotiable instruments law, Norberto Quisumbing for trial technique, Bienvenido Ambion for torts and damages, Mrs. Laurea—I forget her first name (it’s Norberta)—for contract law and family relations, J uan T. Santos, â€Å"who   made us memorize the Rules of Court from cover to cover, my goodness. † He asks Sally for coffee and continues, â€Å"My grades were good, but I didn’t become a bar topnotcher.I answered the exam questions both ways, and for that I got minuses. † Enrile placed 11th, with a rating of 91. 72 percent, in the 1954 bar examinations. If that’s not impressive enough, consider this: He got a perfect score in commercial law. An argument with professor Vicente Abad Santos caused him a â€Å"3† in civil law. â€Å"I didn’t know he was so sensitive. That was five units so bumaba ang average ko (that lowered my average grade),† recalls the man who would have graduated magna cum laude of the UP College of Law class of 1953 but had to settle for cum laude.When student and teacher met again, it was as secretary of the Department of Justice and head of the Board of Pardons and Parole, respectively. â€Å"I gave you a low grade even if you deserved a higher one because you so irritated me,† Enrile recollects Abad Santos telling him. â€Å"Never mind, I am now your boss,† he recalls answering. â€Å"We then became friends. † All his teachers, he says, were good to him, including the ones at Harvard University where, on full scholarship, he earned his Master of Laws with specialization in taxation and corporate reorganization. 9 a. m. I do not wish them to mark me absent at the legislative session,† he says, so he leaves home earlier than most people would expect since the impeachment trial doesn’t start until well after lunch. After taking some time to read the briefs and curriculum vitae of two ambassadors scheduled to pay him a courtesy visit this day, he breaks his silence. â€Å"I never expected to amount to anything. † For a caminero (laborer) like him who made 75 centavos a day smashing rocks on the road from 6 a. m. to 6 p. m. , to be able to get a good e ducation was nothing short of a miracle, he says. At the Harvard Law School, studies attered to him more than anything else. Again, Enrile is able to recall his graduate school professors: Paul Freund for constitutional law and conflict of laws (â€Å"one of the brightest professors ever at Harvard†), Milton Katz for international law (â€Å"he became the director of the Economic Cooperation Administration or the US Marshall Plan in Europe†), law school dean Erwin Griswold for basic courses in income taxation, Stanley Surrey for international taxation (â€Å"he became US Treasury assistant secretary†). â€Å"For corporate reorganization I had Ernest Brown. I could not understand a thing he was saying [in class],† recalls Enrile. My God, I did not know accounting at all! So I forthrightly admitted I had a problem following him. † The professor lent him two books and told him to come back only after he had read the books. â€Å"I did exactly that, an d only then did everything sink in,† Enrile says. â€Å"That was when I learned what corporate reorganization really entailed. † While at Harvard, the Ilocano scholar received a monthly allowance of $170. He managed to have $700 in savings by the end of his stay. â€Å"I didn’t go out much, except for few times with Paeng Salas, Ado Reyes and sometimes Beniting Legarda,† he says.At the time, too, his romance with a girl from Iloilo had just ended. â€Å"Her letters simply stopped,† he says. â€Å"I presumed she had found someone. I presumed wrong. I would find out she never married and that, shortly before she died, she wanted to see me. † He didn’t have to nurse a broken heart for long. While in Massachusetts he met a girl from Costa Rica and, shortly thereafter, marriage was being discussed. â€Å"Her condition was for us to live in her country, where her family had sizable land holdings,† recalls Enrile. â€Å"I said no. I h ad just met my father. He was as happy as I was to meet him.How could I agree to live in Costa Rica? † 9:20 a. m. Enrile swings by the legislative session in the same hall where he is to preside later and is marked â€Å"present. † Senate President Pro Tempore Jose â€Å"Jinggoy† Estrada is presiding over a group that includes Vicente Sotto III, Franklin Drilon, Gregorio Honasan, Ralph Recto, Joker Arroyo, Ramon Revilla Jr. , Antonio Trillanes IV, Manuel Villar, Manuel Lapid, Alan Peter and Pia Cayetano, Teofisto Guingona III, and Francis Escudero. Out of their robes the senators are easily recognizable. Senator-judge Juan Ponce Enrile as presiding officer at the Corona impeachment trial.INQUIRER file photo A short elevator ride takes Enrile to the Office of the Senate President, which has been his since the 14th Congress started in November 2008. He responds to morning salutations from employees not by merely nodding but by verbalizing a hearty â€Å"magandang umaga rin! † In his office, there is time for chitchat before the diplomat guests arrive. He knows exactly where he is in the conversation, so much so that one has to interrupt him and ask how he keeps his focus. He seems taken aback by the question, as if wondering why his focus is a concern. He answers nonetheless. Even before I sleep, I anticipate what is to come, what I’m to encounter. I make up my mind about certain decisions, the direction I’m going to take, and that’s it—unless someone can persuade me to the contrary. But I do not close my mind. I am not against hearing other positions. I need to be sure I am not making an error in judgment when I arrive at my present position. † 10:45 a. m. The diplomats arrive, and Enrile receives them in the conference room adjacent to his private quarters. After an hour, he returns with a brisk stride that says so much about his morning exercises and calisthenics. I sometimes dance, even by myself, while watching a dance DVD. I sweat and I get to stretch,† he says. â€Å"Every now and then I drop by the 365 Club at the Hotel Intercon. It’s no longer what it was in the days of Ka Doroy [then dean of newspapermen Teodoro Valencia–Ed. ] and Mesiong Yabut [former mayor of Makati–Ed. ], but I still have friends there. My sister Armida is also a member. † The relationship with Armida Siguion-Reyna has an interesting back story. The boy who was given his mother Petra’s family name, Furraganan, found out who his father was while he was getting ready to join the guerrillas in the last World War. Anakka iti ruar. Ponce ti nagan ti tatang mo. Maysa nga abogado. Awan ditoy, adda didiay Manila,† his mother had confessed to him in Ilocano. (You are my child out of wedlock. Ponce is your father’s name. He is a lawyer. He is not here, he is in Manila. ) From that day on, Juanito went by the nom-de-guerre Valentin Ponce, the first after his day of birth, which is Feb. 14, and the second, in honor of his father. Juanito had two older brothers Eduardo and Eligio, sons of his mother by her first husband Martin Paddayuman, who died early.He also has five younger siblings from his mother’s marriage to Macario Rapada of Ilocos Sur. They were Marciana, Melanio, Luisa, Juliana and Ireneo. The family tree gets more complicated. One day he was invited to the home of Vicente Alvarado, his father’s neighbor in Aparri. â€Å"There I was introduced, without any warning, to Nena, Teresing, Edeng, and Carmeling,† says Enrile. The girls, it turned out, were his father’s children by Rosario Martinez of Cagayan, along with a son named Mario, whose boat had been torpedoed by the Japanese on his way back to Manila to marry his girl.So there before him were four more Ponce-Enriles. Soon he would find out about Nancy, another half-sibling from their father’s liaison with Maria Balisi of Aparri. As far as h e knew then, he had seven half-siblings by his mother and six by his father, whom he had never met. 11:50 a. m. Executive Assistant Tala Maralit walks in with Majority Floor Leader Tito Sotto. Enrile waves the senator in and they huddle. Senator Trillanes comes in next, with a procedural question. It’s a short, quite cordial exchange. 12 noon The Senate President is not one to lunch alone.Four others join him for a Chinese meal of clear soup, steamed garoupa, steamed shrimps, crabs with black-bean sauce and bok choy sprinkled with garlic. He continues with his recollection. â€Å"So I had met some paternal siblings. † Late in August of 1945, Alvarado returned from Manila, with a message for Juanito. â€Å"My father wished to see me, and I was to go with him to Manila at once,† recalls Enrile. In the city, he was brought to a house in Sta. Mesa. After a week, he still had not heard from the father who he had been told wanted so badly to meet him.He would soon dis cover that one of his roommates, William Balisi, was a full brother of the same Nancy whom he met in Aparri. William was therefore also his half brother. William whispered to the young probinsyano that he had disappointed their father, which was why he was doing errands in that household, in addition to holding a day job at the Philippine Charity Sweepstakes Office. â€Å"Don’t be like me,† Enrile recalls William telling him. â€Å"You study hard. † William then informed his younger half-brother that there had been a misunderstanding of sorts and it didn’t look like the Sta.Mesa Ponce-Enriles were going to introduce Johnny to their father. Johnny would have to go see the old man on his own, but how? He hardly knew his way around town. â€Å"Listen carefully now, this is the way to Papa’s office,† William instructed him. From Sta. Mesa, all the way to Legarda, to Azcarraga (Recto Avenue), to R. Hidalgo, to Quezon Boulevard, Enrile found himse lf in Quiapo where he was struck with a baton by an American sentry. â€Å"I had no idea what jaywalking was,† he recalls. He then walked straight to Carriedo, crossed Avenida Rizal, passed the Ideal theater, walked towards the Sta.Cruz bridge, walked around Plaza Sta. Cruz, found Dasmarinas Street, turned left around the corner and went on until he reached Plaza Cervantes. â€Å"And there it was, the Edificio Soriano. I entered the building from Plaza Cervantes. I saw people standing in front of a door on the right side of the corridor. I stopped and watched. William told me to go to the seventh floor of the building. As I stood there, I noticed people rushing out of the door as it opened, and people outside rushing in before the door closed. It was my first time to see something like that. I was afraid I would not get out from there alive.No one had told the boy from Cagayan about the wonderful contraption called the elevator. On the wall facing the elevator door on the se venth floor were the words â€Å"Dewitt, Perkins, and Ponce-Enrile Law Offices. † Juanito approached Santiago Gampued, the telephone operator behind a desk in the lobby, and introduced himself. â€Å"I want to see attorney Alfonso Ponce Enrile. I am Juanito Furraganan. † He was made to write his name on a small piece of paper and told to wait. Gampued returned shortly and motioned him to a narrow hallway that ended in front of a polished wooden door on the northeast corner.Seated behind a large desk cluttered with piles of paper was a man Castilian in appearance—light complexion, bushy eyebrows, hair almost all white, thick eyeglasses over his high-bridged nose. The man stood up upon seeing him. â€Å"He was of medium built and as tall as I was,† recalls Enrile. â€Å"I’d have thought him urbane, if I knew the word then. And imposing. †Ã‚   Although his face was somewhat haggard and marked with lines, Enrile thought him good looking. â€Å" He walked towards me, I met him halfway,† recalls Enrile. â€Å"He stepped forward, raised his arms, put them around me, held me tightly and said, ‘I am sorry, my son. † 1:45 p. m. Gumban has walked in and out of the office twice, perhaps to remind his boss of the time. He sees what he sees and backs out. The Senate President is crying. He apologizes, but is unabashed. â€Å"I break down every time I recall the first time I met Papa. † In October of 1944, he says, he was being beaten up by the Kempetei almost every day, and had no way of knowing if he was going to live or die. â€Å"Now, September of 1945, I find myself being hugged by the father I had only much recently found out about, and he’s telling me I’m not going back to Sta. Mesa. I’m to ride with him to Malabon.He is driving a black, three-seater Chevrolet convertible sports car,† says Enrile. The car stopped in front of the steel gate of a large compound that held a tw o story semi-concrete house a few meters away. They get off. They are met by a handsome woman, two girls and two boys much younger than Johnny. (Raquel, the oldest girl, happened to be with their maternal grandparents in Pinaglabanan. ) â€Å"Papa goes†¦ Papa goes†¦Ã¢â‚¬  He removes his glasses, wipes the tears off the lenses and, half-laughing, half-crying, says, â€Å"Papa said,   ‘Mama, Mida, Nene, Junior, Toti—this is Juanito.He is my son. From now on he will live with us. ’† Enrile was 21 when he was enrolled a high school junior at St. James Academy in Malabon. After his senior year, he had to take a validating examination for all high school subjects from first year to the first semester of third year as his academic records were incomplete. After high school, Juanito was accepted at Ateneo de Manila for his two-year pre-law studies, and graduated cum laude, despite having to work as an assistant librarian in his father’s office .By this time, so many shovels and picks away from his caminero days, he was getting paid P120 a month. The library proved to be most memorable for the advice that came from his father’s senior partner Clyde A. Dewitt, a former Thomasite: â€Å"If you aspire to be a trial lawyer, master the rules of evidence. Gain the habit of knowing thoroughly the facts of every case you handle. Study the case from the viewpoint of the other side as much as you study your side. Learn the technique of cross-examination by heart.You acquire that skill, not from reading books, but from actual practice in the courtroom. To be a corporation lawyer, you must have a thorough knowledge of corporation law, a familiarity with business practices and a working knowledge of accounting. † Before Enrile entered the UP College of Law, his father instructed Mariano Carbonell, a senior lawyer in the same office, to file a petition to judicially change his surname. 2:14 p. m. The Presiding Officer, Sen ate President Juan Ponce Enrile, calls the Impeachment Trial of Supreme Court Chief Justice Renato C. Corona to order.
