Manhood, Power and Respect instead of Childhood Essay Example for Free

Manhood, Power and Respect instead of Childhood Essay Dave Saunders is the main character of the story, the Theme of the Story is â€Å"Looking for Maturity, Respect and Power†. He is tired of been treated as a child, wants to spend his money to whatever he wants, because his mom holds his money, so he just wants to prove to the others that he is a Man. One day he decided to go the local store to buy a gun, which is the store of Mistah Joe, he ask Joe for a catalog, once he gets the catalog he went back home, his mom sees the catalog, and she doesn’t let him to buy, but after he tells her that the house needs a gun and also that he’s going to give the gun to his dad, she gives $2 for him to buy it. Next day he goes to Mistah Joe store to buy the gun, after buying it he goes to the field to admire the pistol. Next day of work, his is so excited that now his has a gun, he takes jenny the mule and goes far away, so he can test the gun, but accidentally he killed jenny. However, when everybody finds out that he is lying about jenny death, he decided to escape and leave all behind. And the story started like this. Dave Saunders 17 years-old, works at Mr. Hawkins fields, there is the place he makes his own money, and also when he begins his desire to get older, powerful and more respect. One day after he works at Mr. Hawkins fields he was heading home and thinking about the discussion that he had with others field hands that day, and also tired of being treated as a child. He resolves to get a gun for himself, so he can show more power to the others. Instead going home he goes to the local store that they offer a mail-catalog, which is the store of Mistah Joe, when he gets there he asks Mistah Joe for a gun, Mistah Joe Surprised says to Dave â€Å"ain’t nothing but a boy,† (Richard Wright) and he does not need a gun, but he nevertheless offer to sell an old pistol left-hand fully loaded for $2 dollars, Dave goes to his house so excited to ask his mom for $2 dollars to purchase the gun, but when he gets to his house Mrs. Saunders is angry because he has kept the dinner waiting, he sits down and Mrs. Saunders sees the catalog in his arm, and she sizes it, she takes the catalog and tells him to go wash his hands, when he comes back, Dave was so infatuated with the catalog that he did not notice that his father had spoken to him and his food is in front of him. But he knows if he asks his father the money the answer would be a straight NO, and he thinks that his mother is a little easier to persuade. But when he starts a conversation with her, she tells him â€Å"git outta here! Don yuh talk t me bout no gun! Yuh a fool! (Richard Wright), but Dave states that the family needs a gun and after he buys it he will give to his father, Mrs. Saunders agrees to buy the gun but with one condition, as soon as he buys the gun it has to come straight to her possession and also make him promise that he will do it as she said. The first thing he does in the next morning is go to the Mistah Joe store and purchase the gun, while he comes back home, he stops in the field just to play with the gun and he starts shooting imagery objects, afterwards he gets home, he breaks his promise because he hide the gun under his pillow and tells his Mrs. Saunders that the pistol is hidden outside, and it is not true. He leaves his house very early in the morning, ties the pistol in his leg with a piece of flannel and goes to Mr. Hawkins field, he hooks up Jenny the mule and go plow the field far away so he can practicing shooting the gun and no one would hear it, but a fatality happened, he shot Jenny at his first shoot, when he realizes that Jenny is been shot he tried to plug dirty into the bullet hole to stop bleeding, but Jenny soon dies, he is frightened about what happened, he goes back to Mr. Hawkins and trying to tell a believable story about Jenny’s death, afterward someone finds Jenny and Dave make up a story that Jenny had something wrong and all of sudden fell on the point of the plow, but Mrs. Saunders knows it’s a lie, Dave is forced to tell the truth, when he assumed that he killed Jenny, Mr. Hawkins tells him that he has to pay $50 dollars for the mule, and he will take $2 dollars every month of his salary until he pays the $50 dollars. Dave feels annoyed because he has to pay back the mule, also very upset because all the others think he is a child more now than ever before. He decides to leave the city, by doing this he will leave all behind, his childhood and he will become a man as his desire. Dave Saunders is a boy that wants to get the power, the respect, the manhood and also the maturity that most of the men have. The gun seems to symbolize all this to Dave’s eyes, but it’s been showed that is just a phony imagination.

Leonhard Euler | An Introduction

Leonhard Euler | An Introduction Born in Basel, Switzerland on 15th April 1707, Leonhard Euler was arguably the brightest mathematician of all time. The Swiss mathematician and physicist is considered a pioneer in many fields of mathematics. He introduced a lot of the mathematical terminology and notation used today and he is considered the father of mathematical analysis where, for instance, he introduced the notation of a mathematical function, f(x). His contributions to the field of mathematics are in analytic and differential geometry, calculus, the calculus of variation, differential equations, series and the theory of numbers. In physics, although really all his contributions to mathematics apply to physics, he introduced both rigid body mechanics and analytical mechanics (Kline, 401-402). Born to Paul Euler and Margarete Bruckner, Leonhard was the first of six children. He grew up in Riehen but attended school in Basel. Although mathematics was not taught in his school his father had kindled his interest in the subject (Paul Euler had been friends with another great mathematician at the time, Johann Bernoulli) by giving him lessons at home. Euler entered university at the age of 13 at the University of Basel. Although his official courses of study were philosophy and law, Euler met with Johann Bernoulli who advised Euler and gave him help with his mathematical studies on Saturday afternoons (Stillwell, 188). Euler lived and worked mainly in Russia and Germany. First he joined the faculty at St Petersburg Academy of Sciences were he worked at first in the medical department then he was quickly promoted to a senior position in the department of mathematics through the influence of his friend Daniel Bernoulli. He also helped the Russian government on many projects including serving in the Russian navy as a medical Lieutenant. After the death of Catherine I in1740 and because of the tough conditions that ensued, Euler moved to Germany at the invitation of Prussian King, Frederick II to the Prussian Academy of Science were he stayed for the next 25 years of his life. Euler gave much service to the Academy which compensated him generously. He sent most of his works to be published there, served as a representative as well as advising the Academy on its many scientific activities. It is there that he reached the peak of his career writing about 225 memoirs on almost every topic in physics and m athematics (Varadarajan, 11). Euler returned to St. Petersburg in 1766 under the invitation of the then czarina Catherine the Great (Catherine II) to the St Petersburg Academy. During this period he lost almost all his eyesight through a series of illnesses becoming nearly totally blind by 1771. Nevertheless, his remarkable memory saw him writing about 400 memoirs during this time. It is said that he had a large slate board fixed to his desk where he wrote in large letters so that he could view dimly what was being written. He died on the 18th day of September 1783 due to cerebral hemorrhaging. It is also recorded that he was working even to his last breath; calculations of the height of flight of a hot air balloon were found on his board (Varadarajan 13). Eulers contribution to Mathematics and Physics was a lot. His ideas in analysis led to many advances in the field. Euler is famously known for the development of function expressions like the addition of terms, proving the power series expansion, the inverse tangent function and the number e: ∑ (xn/n!)= lim ((1/0!) + (x/1!) + (x2/2!) +†¦+ (xn/n!) ) =ex The power series equation in fact helped him solve the famous 1735 Basel problem: ∑ (1/n2) = lim ((1/12) + (1/22) + (1/32) + †¦+(1/n2)) = Ï€2/6 He introduced the exponential function, e, and used it plus logarithms in analytic proofs. He also defined the complex exponential function and a special case now known as the Eulers Identity: eiφ = cos φ + isin φ And eiÏ€ + 1= 0 (Eulers Identity) In fact, De Moivres formula for complex functions is derived from Eulers formula. Similarly, De Moivre is recognized for the development of calculus of variations, formulating the Euler-Lagrange equation. He was also the first to use solve problems of number theory using methods of analysis. Thus, he pioneered the theories of hyperbolic trigonometric functions, hyper geometric series, the analytic theory of continued fractions and the q-series. In fact, his work in this field led to the progress of the prime number theorem (Dunham 81). The most prominent notation introduced by Euler is f(x) to denote the function, f that maps the variable x. In fact he is the one who introduced the notion of a function to the field of mathematics. He introduced, amongst others, the letter ∑ to mean the sum, Ï€ for the proportion regarding the perimeter of a circle up to the span or the diameter, i for the imaginary unit, √(-1) and the e (2.142†¦) to represent the base of the natural logarithm. Euler also contributed to Applied Mathematics. Interestingly enough, he developed some Mathematics applications into music by which he hoped to incorporate musical theory in mathematics. This was however, not successful. This notwithstanding, Euler did solve real-world problems by applying analytical techniques. For instance, Euler incorporated the Method of Fluxions which was developed by Newton together with Leibnizs differential calculus to develop tools that eased the application of calculus in physical problems. He is remembered for improving and furthering the numerical approximation of integrals, even coming up with the Euler approximations. More broadly, he helped to describe many applications of the constants Ï€ and e, Euler numbers, Bernoulli numbers and Venn diagrams. The Euler-Bernoulli beam equation (one of the most fundamental equations in engineering) is just one of the contributions of the mathematician to physics. He used his analytical skills in classical mechanics and used the same methods in solving celestial problems. He determined the orbits of celestial bodies and calculated the parallax of the sun. He differed with Newton (then the authority in physics) on his corpuscular theory of light. He supported the wave theory of light proposed by Hugens. Eulers contributions to graph theory are at the heart of the field of topology. He is famously known to have solved the Seven Bridges of Konigsberg problem, the solution of which is considered the first theorem of planar graph theory. He introduced the formula V-E+F=2 It is a mathematical formula relating vertices, edges and faces of a planar graph or polyhedron. The constant in the above formula in now called the Euler characteristic. Euler is also recognized for the use of closed curves in the provision of explanation concerning reasoning which is of syllogistic nature. Afterwards the illustration or diagrams were referred to as the Euler diagrams. The Number Theory is perhaps the most difficult branch of mathematics. Euler used ideas in analysis linking them with the nature of prime numbers to provide evidence that the total of all the reciprocals of prime numbers diverges. He also discovered the link between the primes Riemann zeta function, what is now called the Euler product formula for the Riemann zeta function. Euler made great strides in the Lagrange four-square theorem while proving Fermats theorem on the sum of two squares, Fermats Identities and Newtons identities. Number theory consists of several divisions which include the following: Algebraic Number Theory, Combinational Number theory, Analytic Number Theory, Transcendental number theory, Geometric number theory and lastly we have the Computational Number Theory. For his numerous contributions to academia, Euler won numerous awards. He won the Paris Academy Prize twelve times over the course of his career. He was elected as a foreign member, in 1755, of the Royal Swedish Academy of Sciences while his image has been featured on many Russian, Swiss and German postage stamps. Above all, he was respected greatly amongst his academic peers demonstrated by a statement made by the great French mathematician, Laplace to his students to read Euler since he was the master of them all (Dunham xiii). Though not all of the proofs of Euler are satisfactory in regard to the current standards or principles used in mathematics, the ideas created by him are of great importance. They have set a path to the current mathematical advancements. To conclude, we can therefore say that Euler is a very significant person in the development and advancement of Mathematics. His work has contributed a lot to mathematics up to the current period. References Dunham, William. Euler: The Master of Us All. Dolciani Mathemathical Expositions Vol. 22. MAAA, 1999. Kline, Morris.

Planning and Maintenance Problems

Planning and Maintenance Problems Plan and Maintenance Problem 1 To calculate to peak operative temperature in this room in August, some assumes are made before calculation: The operative temperature in adjoining rooms is equal to that for the module under consideration and hence heat glow occur only through the outside window-wall; The window will be open during the day and close at night; The thermal transmittance of the window frame is equal to that of the glass; There are no internal blinds, therefor the solar gain to the air node is zero (Sa =0) According to the equation (5.42), this calculation will be divided into three parts. First, find out the mean operative temperature. Second, find out the swing in operative temperature. And find out the peak temperature in the final. Calculation: Area: External wall = 3.08m2, Internal wall = 40.88m2, Internal floor = 19.8m2 Ceiling (intermediate floor) = 19.8m2, Glazing (include. frame) = 7.0m2 Volume of room = 55.44m3 Summed values: Summed area = 90.56m2 Summed U Value = 22.1/WK-1 Summed U Value = 321.2/WK-1 First part Mean operative temperature: Solar Gain through glazing (Table 5.7): = 0.62 x 177 x 6.3 = 691.36W Internal heat gain: = (792 + 1280 + 1584) / 24 =152.33W Fabric heat gain (Table 2.34(h)): = (3.08 x 0.49 x 26.9) + (7 x 2.94 x 19.8) = 448.08W Total gains to environmental node: = 691.36 + 152.33 + 448.08 = 1291.8W Total gain to air node: = 0 + (55.4 x 19.8) = 1097.7W Room ventilation conductance (Table 5.2): =1/3 x 3 x 55.44 =55.44WK-1 Thermal response factor for the room: = (321.2 + 55.44) / (22.1 + 55.44) = 4.9 Room conductance correction factor; = 3 [55.44 + (6 x 90.56)] / 22.1 + (18 X 90.56) = 1.09 Mean operative temperature at center of room: = [1097.7 + (1.09 x 1291.8)] / [55.44 + (1.09 x 22.1)] = 31.51K Second Part- Swing in operative temperature: Swing in solar gain (Table 2.30 and Table 5.7): = 0.44 x 6.3 x (603 – 177) = 1180.9W Swing in structural gain (Table 2.34(h), and given time lag factor (9.5h)); = [ (0.18 x 3.08 x 0.49) x (11.7 – 26.9) ] + [ (1 x 7 x 2.94) x (24.8 – 19.8) ] = 98.77W Swing in internal gain; = [ (2 x 80) + ( 10 x 19.8) ] – 152.33 = 205.67W Swing in ventilation heat gain: = 55.44 x (24.8 – 19.8) = 277.2W Total swing in heat gain to environmental node: = 1180.9 + 98.77 + 205.67 = 1485.3W Total swing in heat gain to air node: = 0 + 227.30 = 227.30W Mean-to-peak swing in operative temperature Room admittance factor with respect to operative temperature; = 3 [ 55.44 + (6 x 90.56) ] / [ 321.2 + (18 x 90.56) ] = 0.92 The swing in operative temperature at 12:30: (at 12:30) = [ 277.2 + ( 0.92 x 1485.3) ] / [ 55.44 + (0.92 x 321.2) ] = 4.68K Final Part: Peak internal operative temperature: = 31.51 + 4.68 = 36.2 °C As the result, the temperature is too high in the office space, some issues of shading or cooling should be required to reduce the risk of overheat. Problem 2 2a) During project handover, the operational risk management cycle starts with the first implementation procedures by creating the risk inventory through risk identification and risk assessment. Starting with risk identification and assessment, the better the risk assessment and the risk information gathered is structured; the more successful will be the future continuing reassessment process. Good results for risk evaluation are achieved if unit heads and risk or process experts agree on the valuation of the risk. Then, risk mitigation and control system is carried out in view to adequately assessing the impact of an identified risk on the organization’s business, one has to consider existing controls and mitigating measures that already reduce the likelihood or severity of the risk scenario identified. A risk mitigating measure is usually a one-time measure for which an implantation date and a responsible person are defined. Risk scenario, mitigation measure, control, and loss event help to keep track of the implementation steps. These results in improved transparency, efficiency and data integrity compared to the widespread solutions that typically create problems with regard to user access rights, data integrity and confidentiality. Followed by risk mitigation and control system is risk controlling and reporting. The goal of the risk management process is to keep identified risks in line with the risk policy and risk strategy approved by the Board of Directors and the executive team. This process could assure existing controls are actually performed and newly approved risk mitigating measures are implemented as planned. Lastly, followed by the above steps of operational risk management processes, simple risk aggregation and consolidation methods can be introduced. Grouping risks by categories to look for worst-case risk scenarios, consolidating risks across business units and evaluating dependencies, correlation or diversification potential between risks can be introduced already with relatively simple methods and are an important step towards an integrated risk perspective. Based on the structured risk information gathered and the integrated perspective on all relevant risks, mitigation measures and implemented controls, the risk manager is able to produce risk reports according to the need of any type of management level. 2b) There are a number of elements involved in the development and implantation of operational risks. They could be divided into Pre-handover activities and post-handover activities. The following responsibilities should be worked among the project sponsor, building owners, contractors and maintenance providers. Regarding Pre-handover activities: First, developing commissioning program which including the calibrating, testing and running of building systems, services and equipment to ensure the building is ready for use. Sometimes, the manufacturer’s representatives may be present on site to authorize the operation of services and equipment. To make sure the services and equipment have been correctly installed and functioning. Calibrating the control instruments and systems to ensure energy conservation and environment conditions are maintained. Second, transferring of documentation to the client is involved in the development and implementation of operational risks. For example, in terms of building service, the building documentation may include: statutory authority permits and approvals, including progressive building certifier approvals. Providing plant, equipment, services and system information and schedules, including recommendations regarding lifecycle costing, â€Å"as-built† building plans and commissioning data, service maintenance requirements, operation and maintenance manuals covering design and operating parameters, service maintenance schedules, maintenance and cleaning products, tools and spare parts. Third, the project contractors should assist the building owner or maintenance providers to determine the building maintenance requirements. Forth, develop handover training program to familiarize the building owner and maintenance provider personnel with building equipment and systems. It is a good practice as training sessions coordination could utilize the expertise of the design and construction teams such as subcontractors. Effective training will let the building users and owners obtaining knowledge to manage the building and its fixtures, fit-outs, equipment, services and systems. The training contents may include occupational instructions and coincide with the handover of building documentation. Regarding Post- handover activities: First, identify outstanding defects and rectify all outstanding defects prior to final completion. If defects or omissions are identified by the building owner after final completion. Second, monitoring maintenance and update building asset records is involved in the implantation of operational risks. Most building contracts have a defects liability period, typically for twelve months from the practical completion. Therefore, maintenance activity should be monitored and maintenance records should be continually updated to reflect any new defects and rectification works. And these records should be added into a defects report, including the details of maintenance activities undertaken. The certificate of final completion confirms that all contractual requirements have been met, including the rectification or acceptance of all outstanding defects and attendance to all omissions. Forth, project files and accounts are to be closed which allow easy auditing in the future. Substantial records created or received by the design and construction team must be sorted, indexed and recorded to create an auditable project trail. Care must be taken to store all financial records securely. Undertake final completion inspection to ensure satisfactory rectification of all outstanding defects. Last but not least, update and maintain asset register and other relevant asset management systems. Problem 3 3a) Operating temperatures The electrical energy produced by biomass gasification CHP plants can be consumed directly or injected into the network. The production of thermal energy can be specified at below: High-temperature heat (steam or thermal oil, up to 200 ° C) applies for industries which consume heat. Low-temperature heat (hot water at 90-95 ° C) applies for industries which consume heat, urban heating networks by hospitals, schools, government bodies, swimming pools, and industries linked to the wood sector that have co-products and thermal energy requirements. Cost The capital costs of the biomass CHP processes are much higher than fossil fuel fired CHP systems. Small-scale biomass CHP is undergoing trials in the UK. Biomass CHP offers a carbon saving potential for large sites (e.g. over 20 MWe). At these scales, biomass CHP will typically use steam turbines linked to district heating. Environmental regulation / considerations To apply biomass CHP, several matters should be considered. Provide a suitable supply chain for biomass fuel. The site access for large lorries delivering the fuel and storage space for the fuel. The route and mechanism to transport fuel from the store to the boiler and the plant room space around the boiler for cleaning. Integration into the building engineering system Building systems are usually connected to the network via a heat exchanger. Whilst there is some amount of thermal loss from the heat distribution infrastructure, the aggregation of small heat loads from individual buildings into a single large load allows the use of large scale heat technologies. 3b) A district heating scheme comprises a network of insulated pipes used to deliver heat, in the form of hot water or steam, from the point of generation to an end user. District heating networks provide the means to transport heat efficiently. They can currently be built up to around 30km from generating plant and distribution networks can be hundreds of kilometers long. The development of the district heating scheme is benefit to the community include avoided costs of energy, through the use of surplus and wasted heat energy, and reduced investment in individual household or building heating equipment. Problem 4 4a) CBM is a short form Condition Based Maintenance. It is a maintenance strategy that adopted the actual condition of the asset to decide what maintenance needs to be done. It acts as a condition monitoring since it provides an instantaneous indication of a machine’s condition, ensuring critical systems maintained in top condition and spot the upcoming of plant failure. More, it helps improve the conventional maintenance regime by evaluating indicative parameters of plant condition such as temperature, vibration, oil condition, power quality. CBM is a highly effective maintenance strategy which benefits to safety and reliability nature industries such as aircraft industry, semiconductor manufacturing, nuclear, oil and power etc. The advantages examples are stated as following: First, it enhances fault detection in many plant items. Second, it reduces failure rates, labour time and repair budgets. Third, by carrying out the CBM, it gains the greater understanding of plant performance, and thus improves the energy efficiency and worker safety. 4b) As mentioned in 4a), there are a lot of benefits by adopting CBM. Below are the five different CBM methods examples which would help enhance fault detection in plant items and reduce their failure rates. First, acoustic emission monitoring which monitoring defect the naturally occurring high frequency structure borne elastic waves which are produced in materials under some form of stress. Acoustic emissions are the stress waves measuring in dB at high frequency 20kHz to 1 MHz. The instrument is commonly used to listen and measure the acoustic signals emanating from items such as pump’s bearing to define the condition with the plant during it operation. It has a good signal to noise ratio and is not affected by background noise. Second, Vibration analysis which forecast the condition for most machines with moving parts and all rotating machinery has a degree of vibration due to difficulties in balancing the moving parts. For example, bearing degradation and misalignment, to assess plant condition to enhance fault detection and reduce failure rates. It measured in dB at lower frequency range of 100Hz to 10KHz. When faults begin to appear in plant items, the normal vibrations begin to show signs of change. When these vibration measurements are â€Å"trended† over a period of time, the change in the plant conditions can be seen as a graphical representation. It can indicate when lubrication is required, whether the lubrication has been successful and the condition of bearings. Moreover, any misalignment, loose components and other problems that cause the machine to vibrate can be detected, giving maintenance staff the chance to intercept faults and maximise the effectiveness of these tasks and their time. Third, application of Ultrasonic thickness testing uses complex electronic equipment to generate and detect reflections of ultrasonic vibrations from interfaces between materials. Any material that transmits mechanical vibrations can be tested. It is the best method in terms of cost-effectiveness and the ability to detect irregularities in a metallic system. For example, it can read its thickness by simply touching the steel with the measurement head. Contact is usually assured by first removing visible corrosion scale and then applying petroleum jelly or another couplant before pressing the probe against metal. It could detect the occurrence of pitting and cracks both internally and externally resulting from corrosion, microbial and chemical contamination and general wear and tear. Therefore, it avoids the possibilities of leaking and potential failure of critical systems. More importantly, the testing is used to inspect metal to determine quality and safety without destroying or compromising its integrity. Forth, Thermography could be used to evaluate plant condition by obtaining temperature observations of building service pant. The deviation in temperature at which particular pieces of plant operate is often indicative of plant condition. The radiation emitted from the surface of an object is a function of the object temperature with the infrared element of the radiation being measured and converted into an equivalent temperature. The thermal image is constructed from a multitude of point measurements. And the point temperature values are represented on a grey or colour scale. Last, Lubricant and fluid analysis. Microbes can induce corrosion of steel and non-ferrous metals or they can accelerate normal electro-chemical corrosion processes. This mechanism can be occurred directly or indirectly. The analysis will reveal things like oil contamination, incorrect fill levels, as well as a breakdown or degradation of the lubricant’s composition. The procedure is performed by taking a small sample of the lubricant from the machine in question and sending it to laboratory for aassessment of the presence of the organism. 1

Time Travel Essay -- essays research papers fc

Time travel is feat thought by most to be impossible. After all time travel is what many science fiction movies are made of. Let us not forget such movies as â€Å"Back to the Future† or â€Å"The Time Machine.† Yet unlike those movies time travel is not necessarily fiction. â€Å"We are in our own time machines, our hearts are pumping blood, we're breathing, we are existing through time (at least until our own personal time machines seriously malfunction).† (Need help citing this!) Still surrounding this topic is a series of theories, and surrounding these series is a number of flaws. Theories and flaws that need to be explained to fully understand the idea of time travel. First things first we must state the basics.   Ã‚  Ã‚  Ã‚  Ã‚  To begin with throw away whatever you thought you ever knew about time travel. There is no such thing as working time machines, you can’t go back in time by falling into a black hole, and sitting in a tub of water is not going to change you molecular structure and send it back in time by having you float through a wormhole. Time travel is achieved through speed; theoretically you must reach close to light speeds to go forward in time and faster than light speed to go back in time, according to Einstein’s theory of relativity mind you. Einstein’s theory of relativity is the basis of all time travel theories (Davies 1), â€Å"The essence of his prediction is that time is not absolute and universal but depends on the observer’s state of motion.† (Davies ...

The Handmaids Tale Essay -- Margaret Atwood Handmaids Tale Essays

The Handmaid's Tale The Handmaids Tale, written by Margaret Attwood, goes on to explore the consequences that come to be from the reversal of womens rights in a society called Gilead. It is what one can consider a cautionary tale. In the new world of Gilead, a group of conservative religious extremists have taken power, and have turned the sexual revolution upside down. The society of Gilead is founded on what is to be considered a return to traditional values, gender roles and the subjugation of women by men, and the Bible is used as the guiding principle. It differs completely from the society, which was once the place in which Feminists argued for liberation from the traditional gender roles. What women had worked hard for in the area of gaining rights to birth control, legalization of abortion and an increasing number of active female voters, had been completely reversed in a short period of time. Not only were women now forbidden to vote in Gilead, they were also denied the right to read or write, according to the new laws of the establishment. The Handmaids Tale portrays that of a totalitarian society, and reflects a dystopia, which goes on to explore the interaction between sexuality and politics. The main character within the novel is Offred, who also happens to be a handmaid in the Republic of Gilead. Offred is not the Narrators real name; it is her handmaid name, which is derived from the word of followed by her Commanders name. Because of low birth rates, Handmaids are assigned to bear the children for the elite couples within Gilead, who have trouble conceiving. Offred serves the Commander and his wife Serena Joy. Serena was once an advocate for the concept of traditional values, before the establishment of Gi... ...ppression and the dangers of a patriarchal society. The Handmaid's Tale has many elements of social decline written into its plot. From the way women are mistreated to the way corruption and evil have infiltrated the government and army, to the way the black market plays a key role in many people's lives causing a majority of society to become criminals makes it clear how social decline plays a key role in the book. There is also a strong sense of moral decline in the book. If a person, regardless of sex, doesn't fit into the role expectation, he or she is eliminated, exiled from Gilead, and left for dead. Dystopia, the final determinant in the success of The Handmaid's Tale is an imaginary world gone sour through idealism that fails to correspond to the expectations, principles, and behaviors of real people.

An Analysis Of Environmental Toxicology Environmental Sciences Essay

Environmental Toxicology is a quickly developing field concerned with the research how natural and semisynthetic pollutants impact the wellness of worlds, wildlife, and whole ecosystems. It involves application of a assortment of techniques to analyze the impact of toxic agents on life beings and provides powerful tools for measuring the hazards associated with the presence of these agents. It draws on a assortment of scientific subjects to depict, step, explain and predict the badness and frequence of inauspicious effects on life beings due to environmental poisonous exposure. Pollution, depletion of resources and decomposition of ecological maps are of planetary, regional and local concerns. Environmental toxicology nowadayss many practical applications to these jobs. The findings are used by authorities bureaus to put new pollution control criterions and to analyse the badness of harm in an ecosystem and develop the smartest ways to travel about cleaning it up. Land development co mpanies may besides work with environmental toxicologists to do certain that glade and building attempts are every bit environmentally-friendly as possible. It involves proving dirt, H2O, and air samples to look for the beginning pollution, and utilize their findings to better understand wellness impacts on native species. Pakistan, as developing state, is confronting challenges with a figure of serious environmental issues such as devolution of natural resources, industrial and vehicular pollution, pollution of coastal environment, impairment of human wellness. Sum uping in fiscal footings, the one-year cost of environmental disparagement in the state is about 4.3 % of GDP ( US $ 4.3 billion ) . This workshop is about the turning sum of pollution in Pakistan. Examines findings of different surveies turn outing that wellness is being adversely affected by a assortment of environmental contaminations. The above state of affairs has arisen due to a figure of factors including high pop ulation growing rate, predominating poorness, unplanned urban and industrial enlargement, deficient accent on environmental protection in the authorities policies, deficiency of public consciousness and instruction and deficiency of institutional capacity and resources for effectual environmental direction. To forestall continued environmental debasement and the diminution of human & A ; environmental wellness, interactions between human, other life beings and the environment have to be in harmoniousness. This is accomplishable through an integrated, holistic attack embracing instruction and research activities in natural scientific disciplines, socio-economic and political factors with technological, economic and socio-cultural intercessions. Increasing consciousness of environmental debasement is ensuing in proliferation of environmental statute law throughout the universe. This thrust towards greater environmental protection has created a demand for scientists skilled in measurin g environmental resources and more significantly the jobs associated with their development. Environmental appraisal may be required to measure the biological, physical or hydrological resources of any environment, and to put these resources within a wider geographical context. This workshop is an attempt to supply a wide foundation of scientific based accomplishments to germinate, fiting environmental professions, peculiarly in countries associating to environmental protection and direction. Furthermore, the national and international demands have been under concern for better environmental direction understanding the inter-relationship between sustainable economic development and environmental protection. Opening comments from Prof. Dr. Muhammad Ashraf, Chairman section of pharmacological medicine and toxicology/the Director Research UVAS, were followed by that of Prof. Dr. Mohammad Nawaz, Vice Chancellor of the Exchequer UVAS, and Prof. Dr. Mrs. Kausar Jamal Cheema, Dean Faculty of Natural Sciences, Lahore College for Women University, all of whom emphasized the importance to use the corporate wisdom in proviso of improved methods for toxicity appraisal and rational agencies for gauging wellness hazard in order to advance public wellness and to supply a better and safer environment to forestall wellness jobs before they occur. They added further it is our mission to develop new environmental toxicologists and reference pertinent environmental toxicology inquiries through instruction and research in countries such as chemical destiny, bioavailability, biological consequence, toxicokinetics, and mechanisms of action. A focal point on interdisciplinary attacks and scientific accomplishm ents is cardinal to our instruction and research activities. Dr. Sohail Ejaz ( co-author of this study ) , PhD, University of Cambridge, UK co-ordinator and workshop organiser presented on the advanced appraisal techniques for measuring impact of Air Pollution upon Neuroinflammatory diseases of Central nervous system and how these surveies could be implemented in our research labs. New dimensions have been added to the array of result steps. Medical outcomes research now recognizes that patient wellbeing should be loosely conceptualized and measured strictly, in add-on to sing the biological procedure of the disease itself. As a consequence, health-related quality of life, the perceptual experience of wellbeing, is now considered a necessary constituent of results research. Toxicologic surveies have besides gained in edification through incorporation of more sensitive indexs of consequence and the careful tracing of the relationship between exposure and biologically relevant doses to aim sites, which may now be considered at a molecular degree . He besides gave an overview of all his research activities conducted at Department of Clinical Neuroscience and how to work upon such techniques in our state with scarced resources and what marks to be achieved farther to get the better of environmental pollution issues in Pakistan. Dr. Sohail Ejaz bring to a stopping point to develop and back up research plans, outreach and other services that address critical issues in environmental wellness and toxicology. An international talker Prof. Dr. Gerry Amor Camer, Dean, College of Veterinary Medicine from University of Eastern Philippines, wide casted through picture conferencing installation. He shared his singular research work on tissue toxicology and presented a talk on â€Å" Understanding the pathology of tissues exposed to assorted toxins and pollutants † . Assessment of the environmental effects of chemicals is complicated as it depends on the beings tested and involves non merely the toxicity of single chemicals, but besides their synergistic effects, genotoxicity, mutagenecity and immunotoxicity testing. He farther elaborated that a figure of stressors affect the environment and sometimes when demoing interactive effects they become hard to quantify or foretell their single effects. Therefore, there is a demand to understand the poisonous effects at molecular degrees to foretell their effects and bing techniques to be invariably modified to supply better agencies of their qua ntification. Dr. Zulfiqar Ali, Department of wildlife and ecology, UVAS, presented on Beginnings and Health effects of different Air pollutants. The mechanisms for patterning and understanding the destiny of air pollutants through atmospheric conveyance, deposition into H2O and dirt, bioaccumulation, and ultimate consumption to receptor variety meats and systems in the human organic structure are complex. These require more experimental and theoretical developments in order to bring forth attacks for word picture and appropriate schemes and checks for testing in order to observe the harmful agents and forestall them from making sensitive end points. This seminar and workshop provided research workers from all over Pakistan a comprehensive platform where all aspects of environmental pollution as it exists in our state to be to the full explored and a forum to these professionals and research workers to discourse and present latest research tendencies and consequences in the field of Toxicology. Such enterprises help to back up the survey, analysis, and solution of environmental jobs which are finally impacting the wellness of human existences, animate beings, workss, dirts and over all eco-system unity. Prof. Dr. Muhammad Ashraf highlighted different research activities rendered by the section of Pharmacology and Toxicology in the recent old ages at his establishment. He discussed the constitution of new research labs at the section an attempt to open room accesss to many new dimensions therefore advancing the promotion and application of scientific research related to the contaminations. This included the constitution of Angioge nesis & A ; Toxicology lab ( ATRL ) and a Neuropharmacology lab in the module a progressive measure for Applied Neuropharmacology & A ; Cancer research. He elaborated further that our research aims to find how environmental pollutants interact with cellular maps and give rise to durable inauspicious wellness effects in craniates including worlds. We are peculiarly interested in toxic effects that target the endocrine system, the generative system and the early encephalon development and other systems in craniates. Enzyme-catalysed activation in mark cells and tissues and receptor-mediated responses are of import countries of research. With an debut of these research labs, it is besides an attempt in pulling really high quality pupils across Pakistan and foreign qualified and relevant module members to take lead on feasible research undertakings needed to turn to our country-specific jobs. Speakers from assorted universities and Govt. sections presented their research undertakings and research documents. Mr. Khaleeq Anwar, PhD Scholar, presented his work on â€Å" Impact of Automobile jinrikisha on Public wellness † . He presented grounds that Automobile jinrikishas are among one of the major beginnings of air pollution in Pakistan, contaminations released from them include the major pollutants Carbon Monoxide ( CO ) , Nitrogen Oxides ( NOx ) , Hydrocarbons ( HC ) and Particulate Matter ( PM ) showing their annihilating effects in deteriorating public wellness. To hold a control over contaminations realized by these two-or three stroke conventional jinrikishas CNG jinrikisha were introduced. Mr. Rizwan Ahmad, Assistant Director, Vehicular Pollution Control, Govt. of Punjab, farther extended the talk by showing on â€Å" Advantages of CNG over other fuels † . He presented his survey on the nature of the poisons wastewater by firing natural gas as fuel and a comparative analysis was made between the nature of the contaminations released by both conventional car jinrikisha and CNG jinrikisha. Statistically important information was evidenced that emphasized the usage of CNG jinrikisha to be preferred over the conventional two-or three shot jinrikishas. Lubna Shakir, PhD Scholar, discussed the public wellness jobs aroused due to dispatch of tannery wastewater effluent straight into the land in the metropolis of Kasur. The environment is under increasing force per unit area from solid and liquid wastes emanating from the leather industry. These are inevitable byproducts of the leather fabrication procedure and cause important pollution unless treated in some manner prior to dispatch. The consequence of inordinate pollutant degrees normally found in tannery wastewaters can be terrible. Water is so contaminated that drinkable H2O has high degrees of Cr and other poisons have been reported in appreciable sums unfit to be used by public. She presented a comprehensive talk entitled, â€Å" Chemical, microbiological and toxicological showing of tannery wastewater effluent † . In her work she quantified the assorted poisons and studied their hurtful effects utilizing research lab animate beings by utilizing assorted dilutions of this tannery waterwaste. She farther elaborated her talk that appraisal of the environmental effects of chemicals is complicated as it depends on the beings tested and involves non merely the toxicity of single chemicals, but multiple factors are involved in relation to wellness behaviours, which may frequently ensue in inauspicious wellness results. Zahida Umer, a immature research worker, outlined the informations demoing the Measurement of pollution degrees in different countries of Lahore by utilizing C monoxide, sulfur dioxide metres, and other available contaminant measuring metres and impacter for particulate affair in different countries of Lahore and provided a comparative analysis of these poisons at different countries. She farther lucubrated her talk by explicating different methodological analysiss for air pollution measuring. Air pollution can be straight measured as it is emitted by a beginning in mass/volume of emanation ( e.g. , grams/m3 ) or mass/process parametric quantity ( e.g. , grams/Kg fuel consumed or grams/second ) . Air pollution can besides be measured in the ambiance as a concentration ( e.g. , micrograms/m3 ) . Ambient air supervising informations is used to find air quality, set up the extent of air pollution jobs, assess whether established criterions are being met, and qualify the possible human w ellness hazard in an country. Alternatively, air pollution concentrations can be simulated utilizing computing machine theoretical accounts, and so validated utilizing informations collected from direct measurings at selected proctors or beginnings. Air pollution informations and theoretical accounts are used together to analyze the impacts of control schemes on the ambient air. Kanwal Zahra, Government College University, presented on â€Å" Effectss of industrial wastewater on the thyroid secretory organs of human population † . The human organic structure is vastly complex, and our cognition and consciousness of its complexness continues to turn. One of the most disquieting finds in recent old ages concerns the possible functions of environmental chemicals on endocrinal systems. Among the endocrines ( â€Å" chemical couriers † ) operating within the hormone system are estrogen ( a female sex endocrine produced by the ovaries ) ; thyroid endocrine ( act uponing the map of virtually every cell in the organic structure ) ; and ACTH ( produced by the pituitary secretory organ to act upon the release of epinephrine from the adrenal secretory organ ) . Endocrine systems can be affected by these pollutants by interfering with the normal communicating between the courier and the cell receptors, the chemical message is misinterpreted, bring forthing unnatural response ( s ) in the organic structure. As thyroid secretory organs let go ofing endocrines act uponing the entire metabolic rate of the organic structure, in her survey she evidenced the assorted pathological results of thyroid poisoning by these industrial wastes and could be the possible damaging effects resulted. Prof. Dr. Sharif Mughal, Government College University, discussed the impact of assorted poisons on Marine environment. Petroleum hydrocarbons are found in sea surface movie throughout the universe. The oceans have served as a depository for a battalion of wastes and receive wastewater from rivers, watercourses, and groundwater. Atmospheric deposition of polycyclic aromatic hydrocarbons ( PAHs ) and other hydrocarbons adds to the load of pollutants in the marine environment. Industrial smokestacks, incinerators, outfall pipes, cars, lawn chemicals, agricultural chemicals, places, concerns, commercial ships, and motorised pleasance trade are all beginnings of contaminations. Many of these chemicals are fat-soluble and come to shack in the fatty tissues of Marine animate beings. Some of these chemicals have been characterized as endocrinal disrupters ; some are believed to cut down generative success, to interfere with developmental procedures, and/or to stamp down immune map. Other ch emicals, such as PAHs, do non bioaccumulate in marine mammals but may hold inauspicious impacts on the wellness of Marine animate beings through repeated exposure and metabolic response. He evidenced the above scenario by showing his survey on the Serological and histological alterations in the liver of Labeo Rohita dur due to fluoride poisoning. An attempt to qualify the types of lesions produced by these chemical contaminations found in, the metabolic response to such contaminations, and the extent of tissue harm caused by exposure to these contaminations. He farther elaborated his talk that animate beings are exposed to natural poisons in their native environments every bit good as to man-made chemicals and drugs. Factors that affect the toxicity include ; those related to the poisons, which influence how it A ­A ­enter and finally act upon the factors related to the host animate beings that change its ability to detoxicate or accommodate to the poison. The concluding Lecture of the workshop was presented on the subject, â€Å" Word picture of Environmental pathologies by immunohistochemistry † by Dr. Sohail Ejaz, PhD, University of Cambridge, England. He flesh out his talk that Environmental toxicity encompasses the survey of the toxic belongingss of non merely man-made chemicals but natural besides, including their effects on worlds and animate beings every bit good as their motion and destiny in the environment. It is a demand to develop research techniques for the appraisals of effects of these pollutants and supervising their deadly effects non on human wellness merely but impacting every life being and our eco-system. Therefore seting our joint attempts to supply a better and safer environment to forestall wellness jobs before they occur. Decision: This was a variegate workshop to back up and advance the survey, analysis, and solution of environmental jobs which finally impacting the wellness of human existences, animate beings, workss, dirts, harm edifices and other belongings and upheaval of awareness degree at National and International degree through research and development. We can populate a healthy life in a clean environment and it can merely be achieved by recognizing and understanding the importance of clean environment. Therefore to supply consciousness about the effects of all possible environmental pollutants and the corresponding steps to be taken to diminish contaminations exposure. Besides to promote research techniques for the appraisal of effects of these pollutants and supervising their deadly effects on human wellness and conserving and protecting our environment. Disclosures and Auxiliary Information: This workshop was organized at Department of Pharmacology & A ; Toxicology, University of Veterinary and Animal Sciences, Lahore in coaction with the Department of Clinical Neuroscience, University of Cambridge, UK This meeting was funded by Higher Education Commission, Islamabad, Pakistan.

Examples of How You Would Protect the Rights and Promote the Interests of Disabled People Essay

†¢Respecting and maintaining the dignity and privacy of service users †¢Promoting equal opportunities for service users and carers Example: If encounter a disabled patient that needs to take a bed bath you and he/she cannot manage to give bath to his/herself, first of all you need introduce yourself to them, and explain why you are going to give them a bath and make sure to close the door/curtain for their privacy and always put a cover them if you are going to give them a bed bath. Example: in some schools there are disabled people who are willingly to learn and achieve new goals. And in some cases there are no ramps for the disabled student in school. The college must have ramps and lifts for the disabled student because some of them are in wheel chairs and they can’t manage to climb up in the stairs Give 2 examples of how you would strive to establish and maintain the trust and confidence of disabled people: †¢Being honest and trustworthy †¢Respecting confidential information and clearly explaining agency policies about confidentiality to service users and carers Example: A patient tells you about something that happened to her a long time ago and asks that you never repeat it. Being trustworthy, you never repeat or tell anyone about the secrets of others. Example: The doctor is asking her nurse if how is the treatment of their patient in the public area then the nurse remind the doctor that they are in public area then the nurse need to move place where no one can hear what will the nurse is going to say. Give 2 examples of how you would promote the independence of disabled people while protecting them as far as possible from danger or harm: †¢Following practice and procedures designed to keep you and other people safe from violent and abusive behaviour at work †¢Promoting the independence of service users and assisting them to understand and exercise their rights Example: The patient asked the nurse if she can change the bedding because she is soaking wet. But before changing the bed, the nurse needs to lift the patient and move her into another bed because her patient is unconscious. The nurse needs to call a colleague to help her lift the patient to avoid the wrong technique of manual handling and lifting. Example: There is this patient who is in walk therapy and now this patient wants to use the toilet. Then she asked you not to help her but you know that she can’t handle herself. If you can still help the patient and promote her independence by telling that you will be helping her to stand up to bed. And if crutches are visible, the patient can use it for walking without your help but you need to make sure that you are watching your patient. Give examples of how you would respect the rights of disabled people whilst seeking to ensure that their behaviour does not harm themselves or other people. †¢Following risk assessment policies and procedures to assess whether the behaviour of service users presents a risk of harm to themselves or others †¢Taking necessary steps to minimise the risks of service users from doing actual or potential harm to themselves or other people Example: If you are working in kitchen inside the hospital. And you are about to do meals for the patients, you need to follow the procedures on how will you reduce the risk. Washing hands is the main thing you need to do. Usually before touching any utensils you need to make sure that you are clean and tidy. E.g. hair must be tied up, no jewelleries, make sure you have aprons, clean hands and nails. You can also wear personal protective equipment (PPE) if at risk of exposure to blood and bodily fluids, saliva, mucus, urine, faeces. Example: Give examples of how you would uphold public trust and confidence in social care services whilst providing a service a service for disabled people. †¢Form inappropriate personal relationships with service users †¢Abuse, neglect or harm service users, carers or colleagues †¢Put yourself or other people at unnecessary risk Example: Example: Give examples of how you would be accountable for the quality of your work and take responsibility for maintaining and improving your knowledge and skills about disabled people. †¢Maintaining clear and accurate records as required by procedures established for your work †¢Working openly and co-operatively with colleagues and treating them with respect Example: Two different nurses has been asked to give medication to a disabled child, the first nurse who has duty in the morning has given the right dose but the first nurse forgot to write the time when did he/she gave the medicine so this person write the wrong time of medication. When the second nurse came in this nurse also gave the right dose of a drug but the problem is the nurse didn’t know that the record of time isn’t righ and situation made to slow down the heart rate of the child. This is an example of inaccurate records. To avoid this kind of situation you need to know the †five rights† before giving medication. ïÆ' ¼Right Patient ïÆ' ¼Right Dose ïÆ' ¼Right Drug ïÆ' ¼Right Route ïÆ' ¼Right Time
