Synthesizing Carbonatotetraamminecobalt (III) nitrate: [Co(NH3)4CO3]NO3 The first attempt to dissolve the ammonium carbonate in 30. 0 mL of water failed because some chunks still remained. It was important to grind the ammonium carbonate down to a fine powder because the dissolution process took place very slowly and bigger chunks would not have dissolved. After all of the 10. 012 g of ammonium carbonate was dissolved, the liquid remained clear. The addition of 7. 56 g of cobalt nitrate to 15. 0 mL of water was very fluent and took on a color between dark purple and maroon. When the ammonium carbonate and cobalt nitrate solutions were added together, the new mixture was a blood red. After the mixture was stirred, however, it darkened and became nearly black. The 4. 0 mL of 30% H2O2 solution which was slowly added caused the mixture to bubble, sizzle and gain heat, while staying black. While the solution, which was poured into a large crucible, was concentrated over a Bunsen burner, evaporation occurred very slowly. During evaporation, the solution bubbled a little, gas was evolved, and the dissolution of 2. 49 g of ammonium carbonate in the hot solution was visible due to tiny bubbles. After the evaporation was complete and the volume had dropped to 48 mL, the solution had the same appearance. However, after suction filtering the solution, the color became a lighter purple. After the cold water bath, it looked somewhat powdery on the bottom. Filtering a second time resulted in only a pink/purple powder which appeared somewhat crystalline. When the solid was mixed with a scupula during the 10 minute drying process, it looked a lot more like crystals. The final mass of the crystals was 3. 039 g. The balanced equation for the synthesis of carbonatotetraamminecobalt (III) nitrate is shown below as well as the calculations for determining percent yield. 2Co(NO3)2 + 6NH3 + 2(NH4)2CO3 + H2O2 2[Co(NH3)4CO3]NO3 + 2NH4NO3 + 2H2O Theoretical Yield: Density of NH3 (liquid) = . 628 g/ml Density of 30% H2O2 = 1. 11 g/ml Moles of NH3 = (30 ml)(. 628 g/ml)/(17. 031 g/mol) = 1. 20 mol Moles of H2O2 = (4. 0 ml)(1. 11 g/ml)/(34. 015 g/mol) = . 131 mol Moles of [Co(H2O)6](NO3)2 = . 025 mol Moles of (NH4)2CO3 = . 105 mol Limiting Reactant = [Co(H2O)6](NO3)2 (. 025 mol of [Co(H2O)6](NO3)2)(2 mol of [Co(NH3)4CO3]NO3 / 2 mol [Co(H2O)6](NO3)2) = .025 mol of [Co(NH3)4CO3]NO3 (. 025 mol of [Co(NH3)4CO3]NO3)(249. 066g) = 6. 22 g Percent Yield (Actual Yield/Theoretical Yield)(100) = (3. 039 g/6. 22 g)(100) = 48. 86 % Yield B. Measuring Absorbance Spectroscopy. Two distinct peaks of intensity were noticeable for the absorbance spectrum of the cobalt solution between 350 to 650 nm. Below are the calculations for determining the mass of crystals required to create a solution of the right concentration to produce a spectrum of absorbance at approximately 0. 6. A = ? lC 0. 6 = (100 M-1cm-1)(1 cm)(C mol/L) 0. 006 M = C mol/L mol = . 0006 .0006 mol = (mass)/(249. 037 g/mol) mass = 0. 149 g [Co(NH3)4CO3]NO3 The mass of [Co(NH3)4CO3]NO3 added to 100 mL of water was 0. 149 g. Initially, the crystals were dissolved in a beaker to ease stirring. After dissolving, the solution turned purple. The solution was poured into an Erlenmeyer flask and filled with more water to the line on the flask. Below are the calculations for determining the extinction coefficient at each lambda max. The graph for the absorption spectrum is attached. .579 = (? max)(1 cm)(. 006 M) ?max = 96. 5 .519 = (? max)(1 cm)(. 006 M) ?max = 86. 5 C. Measuring conductivity Below are the calculations for preparing a . 001 M solution of the cobalt complex in 100 mL of water. (. 001 M/1000 mL) = (. 0001 mol/100 mL) .0001 mol = (mass/249. 037 g/mol) mass = .025 g. Below are the calculations for finding k, the correction factor. k = literary value/actual value Literary value = 1384 i seimens Actual value of KCl = 1420 i seimens k = (1384/1420) = . 975 Below are the calculations for finding the conductance of the cobalt solution. Probe reading of cobalt solution = 90 i seimens [((1000)(90 i seimens))(. 975)/. 002M](1x10e-6) = 43. 88 i seimens D. Measuring Magnetic Susceptibility Average empty tube reading = -004 Mass of empty tube = . 884 g Mass of tube with crystals = 1. 022 g Height of chemical in capillary rod = 3. 25 cm. Average filled tube reading = -004 (diamagnetic) Temperature of the room = 18. 6 ? C No calculations required. E. Interpreting Infrared Spectrum [Co(NH3)4CO3]NO3 IR spectrum: spikes at frequencies(cm-1) of 280, 500, 830, 1290, 1380, 1600, and 3300. [Co(NH3)5Cl]Cl2 IR spectrum: spikes at frequencies(cm-1) of 830, 1290, 1550, 3200. NaNO3 IR spectrum: spikes at frequencies(cm-1) of 830 and 1380. Discussion A problem occurred during the conductivity measurements of the cobalt complex. The expected values for conductance were between 118 and 131, but the actual calculated value was 43. 88 microseimens. Clearly, the problem arose during the probe reading in the cobalt solution. It is possible that the probes reading was skewed because it made contact with the glass wall of the beaker. This problem would have definitely lowered the reading relative to what it should have been. The absorbance spectrum of the cobalt complex on the wavelength interval 350-650 nm displayed two distinct peaks, meaning that both ions of the coordination compound were separated. This suggests strongly that the coordination compound was indeed synthesized correctly. The absorption intensities at both lambda maxes were relatively close, around 0. 6. These absorption values were used in the Beers Law equation to solve for the molar absorbance, also called the extinction coefficient. Both molar absorbance values are fairly close to 100, but deviations of 4 and 14 imply that some impurities still remain in the compound, possibly left over from the evaporation process. The coordination compound characterization via magnetic susceptibility was rather simple data requiring no calculations. The reason for this is that the magnetic susceptibility reading of the crystal-filled glass tube was equal to the reading of the empty tube, and that both were negative values. Negative values signify that the coordination compound is diamagnetic, which means that no unpaired electrons are present. The reason for the pairing of electrons can be explained with crystal field splitting. When electrons are introduced to d-orbitals, a change in energy occurs. Electrons will move to orbitals with the lowest possible energy. The ideal behavior for electrons after occupying the dxy, dx2, and dyz orbitals is to pair with the electrons already in these same orbitals. This is true only if ? E, or the energy difference from these orbitals to the dx2-y2 and dz2 orbitals, is greater than the energy cost for pairing with electrons in the lower orbitals. In the case of the cobalt complex, the spin pairing energy is much less than ? E, causing the electrons to pair in the lower energy orbitals. This pairing makes the complex a low-spin complex, implying that it is in fact diamagnetic. The goal of the infrared spectroscopy analysis was to prove that the cobalt coordination compound which was created during this experiment was actually created instead of a different compound with similar properties and bonds. [Co(NH3)5Cl]Cl2 and NaNO3 were available to compare with the infrared spectrum of [Co(NH3)5CO3]NO3. Clearly, [Co(NH3)5CO3]NO3 cannot be the same compound as NaNO3 because they only share one infrared band. Both coordination compounds have a band at 3300 cm-1 which corresponds to a N-H stretch, one at 1600 cm-1 corresponding to N-H bending, one at 1300 cm-1 corresponding to N-H symmetric bending, and one at 830 cm-1 corresponding to N-H bending. The most important difference between these coordination compounds lies in the common spike of [Co(NH3)5CO3]NO3 and NaNO3 at 1380 cm-1. Because these two compounds share this spike while the Cl coordination compound does not, the 1380 cm-1 peak must represent an N-O bond, which is the most significant spike on the NaNO3 spectrum as would be expected. During the synthesis of carbonatotetraamminecobalt (III) nitrate, several factors could have contributed to the relatively low quantity of crystals formed in terms of the percent yield. After calculations, it was concluded that 6. 22 grams of crystals should have been produced. However, only 3. 039 grams was actually produced. One of these factors that may have contributed to the low percent error of 48. 86% is the short evaporation stage. Since time was a factor during the experiment, the solution may not have been given enough time to evaporate any impurities. While the final volume of the solution was verified to be 48 mL, under the designated 50 mL, more impurities could have evaporated. If the solution had sat above a Bunsen burner for a greater length of time, it would have undoubtedly become more concentrated. Another factor which possibly contributed to a low percent yield is measurement errors. Although a good level of confidence can be felt about whether or not the right amounts were added, there is always room for error. A simple miscalculation or slight deviation in a measurement could have thrown off the remainder of the synthesis. Furthermore, a very obvious source of error can be found regarding the filtering system. The crystal product is quite soluble in water for the fact that its ions can be easily separated. For this reason, ice cold water was used whenever contact had to be made with the crystals; the low temperature of the water prevents the dissolution of the crystals to some extent. In the filter, some of the crystals could have dissolved and fallen through, which would have resulted in a poor percent yield. In general, this experiment ran very smoothly and achieved its purpose of providing detailed information regarding the properties and synthesis processes of a transition metal coordination compound. To improve the results of percent yield and perhaps to improve the results in many areas of characterization, the evaporation stage should be lengthened to facilitate the removal of remaining impurities.

Ban of medical marijuana dispensaries in Santa Clarita Essay Example

Ban of medical marijuana dispensaries in Santa Clarita Essay Example Ban of medical marijuana dispensaries in Santa Clarita Paper Ban of medical marijuana dispensaries in Santa Clarita Paper Under 1995 Compassionate Act, it is legal to use, posses, and cultivate medical Marijuana in Santa Clarita. Acquiring, and possessing medical Marijuana is quite easier than any prescribed drug with a doctors presciption. According to the Act, patients are allowed to purchase Marijuana in medical dispensaries, or on the streets provided they have a doctors recommendation, and if they are California residents (Signal). This is usually proved by producing an identity card and a doctors prescription. This is usually used to ensure Marijuana is used, and cultivated for medical purpose, rather than recreational. In many California cities, use of Marijuana is illegal, but in Santa Clarita, it is not a crime to use and cultivate Marijuana as long as the law terms and conditions are applied. Possessing up to twenty eight and half grams of Marijuana is considered as an unarrestable offense, especially if the individual produces sufficient proof to be a resident, and agrees to appear before the court. After conviction for possessing such amounts, a fine of $ 100 is charge, but possessing greater amounts of Marijuana, the offense is considered punishable, and the offender is sentenced in jail for six months, and are charged a fine of $ 500 (MPP). In Santa Clarita, Marijuana is usually found anywhere, especially on sierra highway condos. It is common and popular such that every body between the age of fifteen and twenty five, regardless of color or race. Marijuana has various blends and categories in the city. Among all, medical bud is considered to have greater medical benefit, a factor that makes its price to be higher than others. Marijuana dispensaries in Santa Clarita are legalized by the States government, to supply medical Marijuana to all people who prove to be California residents, and who have doctors recommendation bas a prove of their illness. With these prove, individuals are allowed to cultivate the recommended amount of Marijuana and to use it at home without being arrested. The law protects doctor recommendation to Marijuana users under condition they use the recommended amounts of Marijuana without exceeding the dose. They are expected to use it solely without selling it to other people (MoI). Reports of various tests and experiments show that marijuana can be used to treat illnesses, and disorders such as; post traumatic stress disorder, severe anxiety, arthritis, migraine,glaucoma anorexia as a result of chemotherapy, HIV/ AIDS among others. However, in Santa Clarita, many people use Marijuana for other purposes other than medical. Not all people who use, posses or cultivate Marijuana are sick. Although they usually produce doctors recommendation to escape arrest, the recommendations are either fake or invalid the substance for recreation purposes, and use doctors recommendation as a shield to cover them up against arrest, conviction and charges (Indalecio 70). This has increased the use, possession and cultivation of Marijuana in Santa Clarita, as it is hard to tell who is using it for medical purpose, and for pleasure. Although Marijuana has medical value, its negative effects outweighs the benefits. This has caused conflict and arguments between Federal and State law in Santa Clarita. The Federal law is against the use, possession and cultivation of Marijuana; considering the substance to have many harmful effects to the users, people in the society, and the environment. States law Considers use of Marijuana to have medical benefits (Jan 42). The city council of Santa Clarita, has voted to ban medical Marijuana dispensaries, against the States law. Arguments on the ban of Medical Marijuana Dispensaries. The Federal law, and its supporters such as the city council of Santa Clarita, argues that majority of of Marijuana users are actually sick, and their health does not require Marijuana, and since they need Marijuana for recreational purposes, they decide to get a doctors recommendation to be able to freely access and use the substance without being arrested, convicted, or being fined. They get Marijuana from legalized Medical Marijuana dispensaries (DrugSense FOCUS Alert). The presciption they use as evidence to doctors recommendation are usually invalid. The users make a deal with doctors who recommend use of Marijuana at a pay. In this case, doctors make many false recommendation in order to get high amounts without considering the harm they are subjecting these individuals to. Medical Marijuana dispensaries end up selling Marijuana to wrong people without knowing that the recommendation is invalid. People study the literature on medicinal uses of Marijuana. They get the knowledge and information about the conditions, and symptoms the substance can treat. With the knowledge, people fake condition that would require prescription of Marijuana. Some of these conditions and illnesses, such as pain cannot be tested in a laboratory, so it becomes hard for doctors to determine the actual health status of the patient. They rely on the information provided by the patients, and which in most cases can not be evidenced. Doctors end up using the clinical signs and symptoms to prescribe Marijuana; the persons interest. Once the doctor has recommended use of Marijuana, the Medical Marijuana dispensaries dispense it without knowing the actual health status and requirement of the of the Marijuana to the user (Weedguru). The fact that Marijuana is common, popular, and allowed to be sold to recommended user at any place makes many people to participate in illegal trade at anyplace. These supplies are located near schools and parks. Easy access motivates young children to use substance, while still at school limiting their concentration and participation school. The process of buying and selling of Marijuana near schools and parks is usually distracting. If the medical Marijuana dispensaries can be banned, supply and use of Marijuana can be reduced, as there would be no legalized suppliers, since many people use the legalized medical Marijuana dispensaries to purchase Marijuana for recreational purposes. Medical Marijuana dispensaries, have influence on crimes. In Santa Clarita, crimes such as robberies, burglaries and sale of illegal drugs, especially outside Marijuana dispensary, are related to Marijuana (Zachariah 408). Medical Marijuana, especially the bud is usually sold at higher cost than the others. The crimes are committed either to earn money to purchase and maintain a consistence access of Marijuana, or by users through the influence of Marijuana. The crimes are increased in urban areas where the medical dispensaries are located. The City Council of Santa Clarita consider having the Marijuana dispensaries banned to reduce the number of crimes. In Santa Clarita, medical Marijuana is legalized but the dispensing Marijuana is against the Federal law (Shohov 121). A ban on legalized Medical Marijuana dispensary would mean destroying the back up of illegal dispensing, and a subsequent collapse. This is likely to reduce the use of Marijuana in Santa Clarita. Marijuana has THC as its active ingredient. Doctors recommend Marijuana as a source of this medically beneficial ingredient, which is believed to relieve and manage pain. Many users argue that banning Medical Marijuana dispensaries will limit the access of this beneficial ingredient of Marijuana , and patients will be be suffering prolonged pain (Brust 140). This argument is not sufficient to oppose the proposed ban of the dispensaries in Santa Clarita, since there are other medicines which are presented in form of pills and injectable which can be used to relieve and manage pain, rather than smoking Marijuana. The pills and injectables can be purchased from pharmacies, and medical facilities meaning that even after the ban of medical Marijuana dispensaries, patients can have pain managed by the other medicines from the pharmacies (Earleywine 148). Although Marijuana manages pain, there are other better, safer, and effective medicines which have negative side effects. Marijuana as medicine, has many negative effects to the user, other people and the environment. Its side effects to the user outweighs its benefits. Tests reports show that pot smoking destroys the respiratory organs, brain, heart, lungs and suppresses the immune system. Reports have associated Marijuana with chronic intractable illnesses especially to the habitual users (Alison and Joy 26). The smoke produced by Marijuana is a toxic pollutant. Studies show that the smoke has about two thousand chemicals which occur in a mix that cannot be be measured, predicted and deter ming their stability is hard. This means that those who use Marijuana are at risk of disorders and illnesses caused by the chemicals in the smoke. The smoke also posses problem to neighbors, since the smoke is emitted to the atmosphere (Alicia 1077). Neighbors of smokers inhale the contaminated atmospheric oxygen, and gets effects similar to the smoker. Although non-smokers suffer the harm without knowing, even with the knowledge, there is nothing they can do to save the situation, but if medical Marijuana dispensaries can be banned, the supply of Marijuana can be limited securing their health. Legalizing medical Marijuana is likely to pave way for legalizing other harmful illegal substances. Since there are other illegal substances containing beneficial medical ingredient, the medical Marijuana dispensaries are likely to dispense other harmful substances claimed to have medical benefits (Gieringer 42). A ban of the existing medical marijuana dispensaries will give a sigh of relief since the probability using other harmful substances will be low. Marijuana has both physical and psychological effects, such as loss of short-term memory, and respiratory related illnesses. Although Marijuana has medicinal ingredients, the medicine can only be taken through smoking, a factor that predisposes the user to illnesses related to smoking. For example, smoking Marijuana is likely to relieve pain, but it increases chances of lung cancer, as the smoke is carcinogenic. Marijuana influences its users to a continuous use. When an individual starts using Marijuana it causes a continuous need making the user to continually use it. Studies show that when Marijuana is used continuously chances of losing motivation in many areas in life increases. Users are likely to be trapped, and its negative influence on users motivation has showed poor performance of the users in their career, studies and other day to day activities. Habitual users of Marijuana have a tendency of forgetting thing after a very short time (Schrag 135). They forget very vital things which causes problems to their health, life, and other peoples in the society. For example, a n habitual user of Marijuana is likely to forget medical appointments causing inconsistence in their treatments. When driving they are likely to forget they are sharing road with other drivers and vehicles, causing accidents. They are likely to lack motivation to attend business meeting, where they are expected to represent their Company, a factor that can make their employers to punish them, or even fire them. People need to perform various duties in their life, and need to be responsible as long as they live with others in the society. People need to work to earn income for effective living, and need to attend medical appointments in a consistence manner to ensure that treatment is effective (Boire and Kevin 171). Since many people take Marijuana as medicine to the illnesses they need to follow appointments for effective treatment and recovery. If a patient can forget an appointment as a result of smoking Marijuana a medicine,then it means that the medicine does the patient more harm than good because the more Marijuana is taken to treat the more the loss of memory a greater problem. Use of Marijuana as a medicine need to be stopped, and be substituted with more effective medicines which reduces the patients illness, rather than adding more serious conditions. This can only be achieved by banning medical Marijuana dispensaries to cut the supply of Marijuana. Studies show that Marijuana impairs mental dexterity and visual skills. This has causes many problems and deaths in Santa Clarita. For example, users of Marijuana are not restricted from driving and riding (Cole 8). What happens is they use Marijuana and drive, or operate other machines. This causes many accidents and injuries in the city. Literature shows that use of Marijuana leads to systemic hypertension and can impair peripheral vasomotor, reflexes and nerves. It influences blood flow to the central nervous system, and limits the auto regulation of cerebral vascular Habitual users have show to be at a risk of stroke as a result of poor blood circulation in the central nervous system. Analysis made on the respiratory system of habitual users of Marijuana shows that Marijuana smoke deposits large amounts of tar in the lungs and the bronchioles. When smoked, the smokers hold s the smoke for some time. Similar studies show that the users of Marijuana have an increased mortality rate and a decreased life expectancy (Crotty 177). This is a threat to Santa Clarita, since the city is under crime, health and financial crisis as a result of increased use of Marijuana. Summary Analysis of the medical benefits of Marijuana particularly in Santa Clarita, it is clear that it has more harm to the users and the society at large. Smoking Marijuana influences the criminal behavior in the city, causes physical and psychological harm to users and their neighbors, increases death and mortality rate, and retards the economic development of the city. This shows that it is better to prohibit the use of Marijuana, and substitute it with other medicines which can effectively treat similar conditions and illnesses with little side effects to the user, and the entire society. This explains the reason why the City Council of Santa Clarita, and the Federal Law vote for ban of medical Marijuana dispensary. References: Boire, Richard and Kevin, Feeney. Medical Marijuana Law.

Australian Postwar Art & Film Essay Example | Topics and Well Written Essays - 2000 words

Australian Postwar Art & Film - Essay Example Members of this movement engaged in other activities such as composing, performing, recording, and videotaping humorous songs, which had revolutionary lyrics quoted from Marx. Nevertheless, Burn had achieved an artistic career prior to commencement of these movements; in fact, he had a profound involvement in conventional landscapes and self-portraits. In the beginning of 1965, he ventured into abstract and Minimalist painting. Therefore, this resulted to Conceptual art work and installations, which facilitated participation in the International Conceptual Art Movement. After disbarment of Art and Language movement from the international panorama, Burn seemed to withdraw from the International Conceptual Art Movement. Apparently, in 1977, he decided to go back to Australia, where he joined Australian labor movement via Union Media Services, which as a small company. During this period, he focused on organizing cultural programming for trade union members; exhibitions that show cased their art work, and authored associated essays and commentaries. Furthermore, he focused on publishing articles on Anglo-Australian landscape painting, while others were Albert Namatjira, who was Anboriginal artist of Aranda tribe (Burn and Stephen, 1992, 266). It is evident that Ian was a renowned writer in the realm of International Conceptual Art Movement and guardian of contemporary art; in fact, he served as unofficial mentor to numerous dissertations in esthetics and art history in various universities in Australia (Burn, 1991, 115). It is evident that Burn used his early painting to experiment with strategies was a way of separating perception from cognition. He offered conceptual systems aimed at facilitating perception of different things in various ways, which were in temporal and instinctive order. For instance, he segregated the square canvas into six, hard-edge, quasi-organic shapes in the Re-ordered Painting from 1965. In this painting, he used different colours on eac h of the six utensils; in fact, these organic shapes created a perception in a specific sequence. Therefore, Burn utilized cognitive analysis insentience as a way of redirecting the perception of the audience in their own situation. It is evident that Burn focuses on the theme of status and circumstance of self in his works; for instance, in Blue Reflex from 1966, he expresses functions that reflect the blue lacquered surface. Another example is Mirror Piece from 1967, which proved a question seeking to determine the meaning of self-reflection; in fact, this work entails a horizontal sequence consisting of thirteen framed pages of notes and diagrams (Burn, 1991, 118). Therefore, this led to a reflection and refraction of light, which was relative to mirror under various situations. However, he offers a sequence that ends with a large plain and framed mirror. Furthermore, he offers instinctive perceptual relations, which appears to be a mirror that offers a reflection to different pe ople around the world. This work of art is framed in a gallery in a way that modified people’s perceptions regarding the art object. In this case, Burn’s work of art as a part of International Conceptual Art, by presenting a cognitive system, which is independent of the frames references, whereby this is considered disentanglement of the mirrors from the true meaning.

Managing Workplace Diversity - Assignment Example Although there is no explicit rule applicable in the above scenario, critical thinking is expedient. Most of the indicators direct towards a deserved promotion. The worker has doubled his production and is willing to take up the position they are requesting for. It would not be justifiable to deny promotion on the basis of the condition. However, it is important to out-rightly discuss the stress that comes with the position and implications to his health. No. the worker’s health information is and should remain confidential. The worker should be the only one who chooses to disclose their medical information to whom they wish. Disclosing such information to the team violates the worker’s confidentiality. Prudence would advise on educating on all contagious disease. Training that would focus on HIV alone would obviously make the worker feel like it was directed to them. It is wise to consider the worker and their emotions when handling such training. However, it should not serve as a hindrance of providing useful information such as how to prevent oneself from contracting HIV and other contagious infections. Since HIV can only be managed, it is important to consider their appointment days with the physician. There are a few days he may be down due to the condition, but he has shown increased productivity. In effect, people with HIV, especially in the early stages of the disease, will perform in the same way as healthy people do, except occasionally when the condition pulls them down. In this situation, color and standardized test scores have been given preference followed by alumni relationships. High school grades, high school quality, geography, and leadership have followed with curriculum choices receiving the least preference. An affirmative actioned aimed at correcting a situation should also remain fair, reasonable and rational. Underrepresentation of the minorities should not be corrected by

Descriptive Essay About Mothers Cookies Essay Example for Free

Descriptive Essay About Mothers Cookies Essay Many students enter college expecting good times, knowledge, friendships, and a new sense of direction. When I first got to William Penn I didn’t believe I would gain any of that. As time has passed I realized that WPU does have a lot to offer but everything takes patients. I also had to realize that everything wasn’t going to come easy either. I soon found out that college comes with challenges and struggles because of the great demands and expectations that comes with success. The demands of doing many different things with very little time can become overwhelming. But I believe I’m starting to get the hang of it. There are a limited number of students on the campus so it makes it easier to focus in class that’s something I really like. Putting in long hours and worrying about class does bring extra stress but I’m learning to balance it all out. Coming to WPU has also taught me to have an open ming that I can’t just do the tihngs that I know how to do. I have to try new things that im unconfortable doing. I believe attending this university will open many doors for me. It will also help me mature and become a better student . WPU wiil also help me build my career and start my life on the right path. I chose to come to William Penn becaus I knew that a school far away would give me a better chance to focus on school without too many distractions. Another reason I chose William Penn is because Im very deticated to basketball and coach Henry offered me scholarship money to give me an oppurtunity to play. I also did my research and I noticed that the basketball team had a great season and great program. So I figured it was an honor that William Penn wanted me. I also have lived in Louisiana my whole life so i was really read for the college experience and something different other than Louisiana. So far Im feeling that William Penn was the right choice for me. I needed a new start away from all my problems back home. I was really making bad choices that was starting to lead my life in a direction that i was not prepared for. Ofcourse all my problems are not going to just go away but being at William Penn is giving me an oppurtunity to live my dreams and revatuate myself as a person. Then I will be able to deal with my issues back home as a different person with a better mind set. So I definately dont regret coming to this school because it is keeping me grounded and building character. Read Also:Â  Descriptive Essay Topic Ideas

John Adams and His Roles as President Essay

John Adams was one of the leaders in the fight for American Independence. He was born on October 30, 1735. His presidency began in 1976 through 1800 and was the second president of the United States, after winning the election against Alexander Hamilton. Upon winning the election he became the Chief of State. His most notable accomplishment, as President, was to avoid a war with France, while maintaining American honor. In our opinion he did a good job of this however he was not greatly supported by the Americans at the time. John Adams was not a very popular president of his time. Being the president, and Chief Executive, Adams was allowed to choose his own cabinet. He replaced Washington’s cabinet which consisted of Edmund Randolph, Alexander Hamilton, Henry Knox, and William Bradford. Timothy Pickering of Massachusetts was appointed the secretary of state, Oliver Welcott of Connecticut became the secretary of treasury, James McHenry of Maryland became the secretary of war, and Charles Lee of Virginia was appointed the attorney general. It’s obvious that George Washington had a much better cabinet than Adams did. John Adam’s cabinet was not nearly as sharp or as intelligent as the one of Washington. Obviously, Mr. Adams did not do too good of a job on choosing his colleagues. Another role that John Adams endured was the role as Chief Administrator. In today’s modern world the president would be in charge of agencies such as the CIA and the FBI. In Adam’s days these agencies did not exist. Nonetheless he was still in charge of keeping the government functions running as smoothly as possible. As a believer in centralized government, he helped strengthen the Federal government. As Chief Diplomat, John Adams ran into the biggest problem in foreign policy. The French were attacking American shipping. He sent three representatives to France to try to work out differences between the French and the US government. His emissaries were met by three French representatives demanding a bribe. This became known as the â€Å"XYZ† affair. Infuriated by the absurd 250,000 bribe of the French agents Adams began to prepare for war. He first asked for a provisional army. He also asked for the officers to be commissioned and for recruiting to begin. However, he did not call for an establishment of a large, professional army. Throughout the two years that the possibility of a war had existed, Adams had made it clear to everyone that he put he put his faith in a strong navy. As commander-in-chief he decided he did not want to use the army as an instrument for defense. Adams believed that the only way France could be brought around to treat with American envoys on an even basis is if it was made clear that the Americans were prepared to fight and that they would not submit to any further humiliation. He wanted France to see that the Americans were not backing down and that they were not afraid to go to war with the nation of France. After the â€Å"XYZ affair† John Adams acted on his role as chief legislature. He responded with The Alien and Sedition Acts of 1798. They were designed to crush the conflict. After two years John Adams decided it would be best to reopen negotiations because war with France was not in the best interest of the United States. He signed a peace treaty with France and thereof is accredited with bringing peace between the U.S. and France. Yet another role of the president is to be Chief of Party. We believe that John Adams was a failure in leading his political party as the end of the Federalists came about because of his presidency. During Adams’ presidency, the Federalist party split up. This happened because of how much John Adams and Alexander Hamilton disliked each other. Hamilton didn’t want Adams to be re-elected, and so he critized his performance as a President. Undoubtedly, Adams lost his re-election and Thomas Jefferson, the leader of the Democratic-Republican party, won office. After Adams retirement, and Hamilton’s unfortunate death, the Federalist Party was left without strong leader and steadily grew weaker and weaker. John Adams was not a bad president. However, because of society’s selfish and impatient needs, he was made out to be the enemy. Americans blamed John  Adams for being scared to go to war, but in reality, it’s a lot easier to go to war than it is to keep peace. It’s also quite difficult to go against the majority of ones colleagues who continually pressure you to act. John Adams may not have been the greatest president because of his ambition. However, he was a much better president and showed exemplary qualities as a chief citizen than what he was given credit for. He was a brave and honorable man who gave up re-election by not going to war. It shows real honor when you can give up your own selfish needs for the good of your country. John Adams was a much better president than he was given credit for.

Macbeth Written Response (Act II Polished) Essays - Free Essays

Macbeth Written Response (Act II Polished) Essays - Free Essays Macbeth Written Response (Act II Polished) Dev Brar Throughout William Shakespeare's Macbeth, the literary device of symbolism often occurs. Shakespeare utilizes this literary device , most specifically blood, water, light and darkness to exemplify the inner conflicts of Macbeth's guilt and guilty conscience. Shakespeare uses blood as a trigger for the protagonist, Macbeth. The sight of blood, triggers Macbeth's guilt of committing the treasonous act of killing King Duncan. More specifically, the sight of blood triggers the internal conflict between Macbeth thinking killing Duncan was the right choice or the wrong choice. In scene ii, Macbeth comments on the appearance of his hands after the deed was done, for his hands were covered in the King's blood. "As they had seen me with these hangman's hands" (2 2 35). Macbeth is commenting on how his hands match the hands of an executioner. By Macbeth stating this line it is evident to the audience that Macbeth is in fact feeling guilt. This is the first instance of Macbeth's battle of guilt between thinking that he had made the right choice to kill Duncan and take the crown, or making the wrong choice. After Macbeth refuses to back to the scene to plant the bloodied daggers and smear Duncan's blood on the guards. By macbeth refusing to go back to the scene it means that Macbeth believes that he has made the incorrect option and guilt os now overcoming him, and returning to the scene will only intensify the guilt because of all the blood. This shows that Macbeth is now attempting to escape the sight of blood, but since there is instances of blood used throughout all the other acts this, meaning that Macbeth cannot escape blood, which is a metaphor stating that Macbeth cannot escape guilt either. The usage of water represents purity, and innocence. Lady Macbeth tells Macbeth to wash off Duncan's blood with some water. "Go get some water and wash this filthy witness away from your hand"(2 2 56). By Lady Macbeth telling Macbeth to wash this filthy witness away from your hand' represents an attempt to cleanse oneself of the guilt that Macbeth is experiencing. Macbeth, however does not believe that the water will do the trick. "Will all great Neptune's ocean wash this blood clean from my hand? No, this my hand will rather the multitudinous seas incarnate, making the green one red" (2 2 73-76). Macbeth is stating that all of Neptune's waters could not clean his hands clean of blood, meaning that all the purity and innocence in the world cannot clean Macbeth of his guilt. Macbeth also states that he would turn all the green waters crimson red, this again is due to Macbeth thinking that killing King Duncan has made an internal wound so deep, that is buried with guilt, when a ttempted to be cleansed will turn all the purity that Macbeth sees turn into guilt. Light and darkness is the contrast between good and evil. Light and darkness also represents innocence and guilt. Light and darkness are used to contrast the innocence/good and guilt/evil in Macbeth. The quote "When shall we three meet again That will be the set of the sun" (1 1 4) foreshadows Macbeth's inner conflict of light and darkness, of innocence and guilt. In other instances it is shown that guilt and evil are beating innocence and good. "Stars, hide your fires; let not light see my black and deep desires" (1 4 50-51). Demonstrates Macbeth acknowledging that he will be guilty of Duncan's death in the future, but prays' that the light fades away and that darkness prevails. With the darkness of evil taking over Macbeth, guilt comes with it, so that when Macbeth does an evil deed the darkness inside him grows. However as the darkness grows the hunger for evil greatens, but when satisfied, guilt is a symptom in which one must suffer for all the evil they had done. Shakespeare uses various literary elements to portray themes in his tragic. In act II being guilt through the use of symbolism. Due to the guilt in which Macbeth experiences causes him to act differently. The guilt causes Macbeth to undergo slight character change, creating

A.A. Milne Publishes Winnie-the-Pooh

A.A. Milne Publishes Winnie-the-Pooh With the first publication of the childrens book Winnie-the-Pooh on October 14, 1926, the world was introduced to some of the most popular fictional characters of the twentieth century - Winnie-the-Pooh, Piglet, and Eeyore. The second collection of Winnie-the-Pooh stories, The House at Pooh Corner, appeared on bookshelves just two years later and introduced the character Tigger. Since then, the books have been published worldwide in over 20 languages. The Inspiration for Winnie the Pooh The author of the wonderful Winnie-the-Pooh stories, A. A. Milne (Alan Alexander Milne), found his inspiration for these stories in his son and his sons stuffed animals. The little boy who talks to the animals in the Winnie-the-Pooh stories is called Christopher Robin, which is the name of A. A. Milnes real-life son, who was born in 1920. On August 21, 1921, the real-life Christopher Robin Milne received a stuffed bear from Harrods for his first birthday, which he named Edward Bear. The Name Winnie Although the real-life Christopher Robin loved his stuffed bear, he also fell in love with an American black bear that he often visited the London Zoo (he sometimes even went into the cage with the bear!). This bear was named Winnie which was short for Winnipeg, the hometown of the man who raised the bear as a cub and later brought the bear to the zoo. How the real-life bears name also became the name of Christopher Robins stuffed bear is an interesting story. As A. A. Milne states in the introduction to Winnie-the-Pooh, Well, when Edward Bear said that he would like an exciting name all to himself, Christopher Robin said at once, without stopping to think, that he was Winnie-the-Pooh. And so he was. The Pooh part of the name came from a swan of that name. Thus, the name of the famous, lazy bear in the stories became Winnie-the-Pooh even though traditionally Winnie is a girls name and Winnie-the-Pooh is definitely a boy bear. Other Characters Many of the other characters in the Winnie-the-Pooh stories were also based on Christopher Robins stuffed animals, including Piglet, Tigger, Eeyore, Kanga, and Roo. However, Owl and Rabbit were added without stuffed counterparts in order to round out the characters. If so inclined, you can actually visit the stuffed animals that Winnie-the-Pooh, Piglet, Tigger, Eeyore, and Kanga were based on by visiting the Central Childrens Room at the Donnell Library Center in New York. (Stuffed Roo was lost during the 1930s in an apple orchard.) The Illustrations While A. A. Milne hand-wrote the entire original manuscript for both books, the man who shaped the famous look and feel of these characters was Ernest H. Shepard, who drew all the illustrations for both Winnie-the-Pooh books. To inspire him, Shepard traveled to the Hundred Acre Wood or at least its real-life counterpart, which is located in the Ashdown Forest near Hartfield in East Sussex (England). The Disney Pooh Shepards drawings of the fictional Winnie-the-Pooh world and characters were how most children envisioned them until Walt Disney bought the film rights to Winnie-the-Pooh in 1961. Now in stores, people can see both the Disney-styled Pooh and the Classic Pooh stuffed animals and see how they differ.

Carbon Footprint Auditing and Management Assignment

Carbon Footprint Auditing and Management - Assignment Example According to the Intergovernmental panel on climate change (IPCC), over the next century the earth will experience an average increase of 3.0 to 11 degrees Fahrenheit. This revelation, alongside other credible projections, call for consolidated efforts in mitigating global warming and climate change, adopting necessary remedial measures, and coping strategies, especially for the poor societies (Mark, 2005:173). A recent estimation by the United Nations Environmental Programme (UNEP) indicates that households account a well over 30% of the carbon emissions in to the atmosphere every single day. It is against this background that putting measures in place to curb carbon emissions at the individual and house hold level is critical to all members of the society. Through the various energy usages in the house, the annual average carbon footprints stand at 5.89 tons of carbon. This is way above the national average of 4.46 tons per household. In simple terms, my operations at the house hav e resulted to the emission of these tones of carbon, into the atmosphere every year. With the recognition that carbon compounds, especially carbon oxides, are leading causes of the green house effect and the resultant global warming, this is an alarming rate of carbon emission, resulting from a single person. 1.2 Diagnostic Base-line Energy usage for the various activities in the house is the greatest carbon footprint source. Although the house uses electricity, which does not directly contribute to carbon emissions, it indirectly contributes to carbon emission. This occurs during the production of electricity at the power plant. The turbines that produce the electric power run on diesel generators, where as the distribution, step up and step down functions, are all depended on carbon producing fossil fuels. Therefore, any use of electric energy in the house contributes to carbon emissions in a significant direct and indirect manner (Charles, 2011: 45). After a careful analysis of t he processes and activities that dominate my carbon footprints, energy usage within the house is the leading activity, with conservation and efficiency measures lagging behind. In everyday, routine operation, revolving around cooking, ironing, electronics, and lighting have a profound effect on the amount of energy that the I spend in the house. Further, routine use of electric powered gadgets like the blower, the lawn mowers, and the washing machine also contribute to the high energy figures at the end of the month. This is made even higher by the heating of the house during the cold seasons, and the use of power to run the cooling systems during the hot weather days (Sarah, 2008: 39). Since all these energy-uses are pertinent, the focus turns to efficiency, conservation and green energy technologies, to contain the energy usages, and reduce carbon footprints. The first step will was to change the lighting system in my house, since all the bulbs in place utilize a lot of energy. Al so,
