Reading Journal A Good Man Is Hard to Find Essay

Reading Journal A Good Man Is Hard to Find - Essay Example as been portrayed, it is clear that she has an out fashioned and traditional perspective of life, where life was full of goodness, including respect for people and doing what was right for everyone. Her perceptive in life would hold true during her times, when she was still growing up. However, it is far from reality today, especially with people like Misfits and his friends owning guns. This portrays the fact that the boys do not care about the well-being of their fellow men, and go as far as shooting the family. Due to her view of the world, grandmother even prepares for her death, saying she prefers wearing nice clothes so that her corpse would look good. Looking at grandmother’s character, it can be deciphered that she is ignorant and not flexible enough. This is because she does not adjust quickly to the changing world. Instead, she continues to judge people in her own way and expects them to act just as they did. In her mind, she has created her version of what passes as goodness. T6his she does even after continuously deceiving her family. The narrator mentions, â€Å"The grandmother’s brown eyes were very bright† (311). This can be interpreted as ironic, because to the readers, grandmother appears to be unaware of the reality of the world around her. Even when faced with death when Misfit and his friends come to them with guns, she still calls the Misfit a ‘good man’. Her continuous encounter with children illustrates her eagerness to teach the children ‘good’. The concept of Christianity also comes into play when talking about goodness. It demands that people see the goodness in others, irrespective of their errors. This could probably be the reason why grandmother calls Misfits a good man. According to her, her late husband was a good man. She tells the children about her life, implying that she expects the children to see the goodness in everyone. Grandmother is proud of her spirituality, even when begging for her life. In conclusion, it is

Organic food - Research Proposal Example â€Å"Do you know why that apple is so shiny in the store shelf? Yes, you guessed it, full of pesticides. Yes, full of poisons and chemicals. Why spend time scrubbing your fruit when you should be enjoying it. Pesticides will prolong shelf life, but at the same time, are more damaging to your body† (All About Organic Foods). The organic food contains only organic ingredients and the processing also will be done mostly using natural means. The packing materials also will be biodegradable whenever possible. The advantages of organic system of farming are; it is environment friendly; it sustains diversification in ecosystems and it uses less energy and produces less waste. Organically managed soil will never lose its quality and it has higher water retention ability. Even in drought years the yield will not be decreased because of this property. Organic food and fruits taste better than conventional food. Foods, that are unprocessed and unrefined, or processed and refined as little as possible is called whole foods. It will not contain any ingredients such as salt, sugar, fats etc. All whole foods need not be organic though both of them have some similarities. The life of whole foods may be less because of the lack of basic processing methods. Colorado Denver is one of the main centers of America’s organic food growers. The city is blessed with so many restaurants, hotels and markets which supplies only the organic foods. Grower’s Organic, Door to Door Organics, The Forte, Chinese Bean Sprout, Whole Foods Market, Denver Distribution center,‎ Sazza‎, Winter Park Market, Alberts Organic Inc, Vitamin Cottage Natural Grocer, Humm Foods Incorporated, Vitamin Cottage Natural Grocers, Vegetarian Society of Colorado, Gnc are some of the main organic food suppliers and markets available in Colorado Denver â€Å"In the rush to produce more and more crops to satisfy growing demand producers have had to

Extreme Poverty and the Rights of the Poor Essay Example for Free

Extreme Poverty and the Rights of the Poor Essay Extreme poverty and the rights of the poor has been a high priority of the UN ever since its creation, yet this dilemma are still happening in many underdeveloped and developing countries. To eliminate this problem, public awareness and a genuine cooperation in the global community is required. Extreme poverty and rights of the poor goes hand in hand, because in many third world and developing nations, poor people have no rights. France encourages nations to genuinely cooperate to increase the awareness of the issue and to abolish habits of â€Å"ignoring poverty and the rights of the poor. † The eradication of poverty must begin by providing help to those most affected by the problem. The poor and uneducated makes up the majority of those without any rights, they lack access to the fastest way of escaping poverty, education; therefore, they rarely ever have a voice in their communities. France is well aware that efforts have been made to fight poverty in many regions simultaneously, including Africa, Central and South America, and the Middle East. France strongly believes that the most essential step the UN should take in order to solve this problem is to encourage all nations to provide free education to everyone. In order to reduce poverty and guarantee rights to the poor, free education must be made available to everyone, especially to those that cannot afford it. If this is achieved, people most definitely are able to have a bigger and better access to economic opportunities, a major factor in escaping poverty. In France, it is required for children from the age of 6-16 to attend school. After ninth grade, students can choose whether or not to pursue a higher education, such as high school and college, if not, they can be admitted to a technical school, then graduate from such school and have a professional career. France believe that based on the high efficiency of this method, the UN should carry out similar actions to a global scale by encouraging nations to adopt the same principle. In conclusion, France strongly believes nations must genuinely cooperate effectively in order to reduce poverty and guarantee rights to the poor. The source of this problem is believed to be the lack of access to education due to poverty. Providing free education must be the first step nations should take in order to bring an end to this problem.

Aluminium Presentation Essay Example for Free

Aluminium Presentation Essay Ive done my presentation on Aluminium and will be talking to you about its properties, where its found and its uses and why its the best material for these purposes. Aluminium. Chemical symbol Al. Atomic weight approx 27 Atomic number 13 and electronic configuration 2-8-3. Appearance- pure aluminium is a shiny silvery white material. Down to the molecular level aluminium has a polycrystalline structure where the metal has cooled from different areas of the material where. Where these areas meet are called the grain boundary. This structure gives aluminium its many properties. Density The first thing you notice about aluminium is its relatively lightweight. It has a density of 2,7g/mm3. This is about 1/3 the weight of a piece of steel the same size. Resists Corrosion like many other metals aluminium is very reactive in air and thus a fine layer of aluminium oxide is created on the surface. This provides provides a highly effective barrier to the ravages of air, temperature, moisture and chemical attack. 0.000000635cm Highly reflective Free electrons in the metal absorb the light energy then immediately re emit it.emits 90* of the light that it absorbs. This would not happen if free electrons wernt present. Ductile Aluminium can be bent and shaped extremely easily. This is because of it polycrystalline structure. Along the grain boundaries of the material dislocations in the atoms occur. It is the movement of these dislocations that makes this metal very ductile. This is good for shaping aluminium but very bad for its strength. Strength like many other of aluminiums properties it depends on the purity of the material 99.996 per cent pure aluminium has a tensile strength of about 49 megapascals (MPa), Unlike materials such as steel, aluminium gets stronger as temperature drops. rising to 700 MPa following alloying and suitable heat treatment. Conductance aluminium is one of the best conductors of electricity. Because it is a metal it ontains almost a soup of free flowing electrons which make it very easy for a current to flow through it. Aluminium itself conducts about 63% of that of copper of the same mass. Aluminium is also a great conductor of heat conducting about 220 Watts Occurance Aluminium is the most abundant metal in the earths crust. Only the non metal elements oxygen and silicon are more abundant. The largest deposits of aluminium are found in Australia, Guinea and West Indies. Aluminium does not occur in its pure form but as either an aluminium silicate or as bauxite which consists of aluminium oxide and commonly iron oxide also. As seen in the picture the aluminium ore is a redish colour this is caused by the iron ore mix. Bauxite is produced through chemical weathering of rocks in tropical climate. Extraction The method now used for aluminiums commercial production is the electrolysis. An iron pot, lined with carbon, is charged with cryolite and heated to about 800à ¯Ã‚ ¿Ã‚ ½C by the electric current. For the electrolysis, a bundle of carbon rods is used as the anode, while the pot itself forms the cathode. The oxygen liberated combines with the carbon of the anode to form carbon dioxide, while the aluminium falls to the bottom of the vessel. More alumina is added and the process continued, the molten metal being drawn off from time to time. Uses Aircrafts Mainly because of its lightweight. This feature is utilized by aircraft and can cut the weight down by up to 5 tonnes. This means planes can fly fast and be more economical. This also applies to all transportation allowing increased loading capacity also. Usually it isnt actually pure aluminium because of its poor strength but instead alloys of aluminium which can be as strong as 700 Mpa. Buildings Aluminium is used in construction mainly because of its corrosion resistance. Its is also a very easy material to shaped and mould making it ideal for the uses in construction Electrics Aluminium is a very economical material as an electric conductor and is widely utilized in power transmission cables. Aluminium only has 60% conductivity of copper but weighs a 1/3 as much making it ideal for large power cables. Heat aluminium is about 3 times as thermal conductive as steel. This feature is used in cooking utensils, engines, air conditioners and it is also being used in energy saving equipment such as solar cells. Reflective Because aluminium is reflective of most electric, heat and light waves it is being more commonly used in the insulation of homes. Harsh conditions Unlike steel which gets brittle in cold conditions aluminium get stronger making it the perfect material to use in harsh conditions. Aluminium is now being used on snow-mobiles Cans aluminium is a non toxic material, smooth, easily washable and is hygienic because no germs an grow on it. Also because malleability it can be shaped into any shaped or form making it ideal for packaging Because of aluminiums low melting point approx 600 C it is the ideal material in this age of energy and resource saving to recycle.

Biological Causes of Cancer and Effects

Biological Causes of Cancer and Effects Cancer refers to a set of diseases characterized by the uncontrolled proliferation of cells into a different form against the normal complement of the organism (Kufe Holland, 2003). There are two types of tumors; one is unremitting proliferation of cancer cells develops into tumor tissues and may multiply across to other organs via circulatory systems resulting in metastasis known as malignant tumors and second one those without malignant properties, which are self-limiting, noninvasive and do not metastasise, known as benign tumors. Around 90% of deaths from cancer are due to the metastases (Box Html, 2008). Cancer may concern humans of all ages. According to figures from World Health Organisation (WHO), cancer is the second most mortal disease after cardiovascular diseases. In 2010, around 5.5 million people in India were died due to cancer. 71% cancer deaths occurred in both men and women aged of 30-69 years. The three most common fatal cancers were oral (including lip and pharynx), stomach, and lung (including trachea and larynx) in men, and cervical, stomach, and breast in women. About 30% of cancer deaths are due to high body mass index, low fruit and vegetable intake, lack of physical activity, tobacco and alcohol use. Hence, the medical needs for cancer remain one of the most demanding areas in scientific research (Dikshit et al., 2012; Ferlay et al., 2007). Cancers are first and foremost an environmental disease with 90–95% of cases due to modification in lifestyle and environmental factors and 5–10% due to genetics mutation (oncogenes, tumour suppressor genes and DNA repair genes). Cancer is caused by physical carcinogens (ultraviolet and ionizing radiation), chemical carcinogens (asbestos, components of tobacco smoke, aflatoxin and arsenic), and biological carcinogens (infections from certain viruses, bacteria or parasites). Common environmental factors leading to cancer death include: tobacco (25–30%), diet and obesity (30–35%), infections (15–20%), radiation, stress, lack of physical activity, and environmental pollutants. These environmental factors cause abnormalities in the genetic material of cells. There are certain risk factors for cancers which consist use of Tobacco, alcohol, unhealthy diet and physical inactivity are the main cancer risk factors worldwide (Rayl and Lewis, 2001; Bahls and F ogarty; 2002; Gibbs; 2003). Chronic infections from hepatitis B (HBV), hepatitis C virus (HCV) and some types of Human Papilloma Virus (HPV) are leading risk factors for cancer in low- and middle-income countries. Cervical cancer, which is caused by HPV, is a leading cause of cancer death among women in low-income countries (Newman and Cragg, 2007). It is very unfortunate condition when cancer has been diagnosed; there are a number of treatments available. As cancer refers to a class of disease, it is unlikely that one single cure for all forms of cancer is possible (Pazdur, 2001; Illidge, 2008). The most common methods include surgery, chemotherapy (with one or more cytotoxic antineoplastic drugs), radiation therapy (ionizing radiation). There are other methods of treatment such as targeted therapies (monoclonal antibody therapy), immunotherapy (enhancing, or suppressing an immune response) and hormonal therapy (Goldenberg, 2002; Rosenberg et al., 1986; Byar and Corle, 1988). New methods, immunotherapy have the advantage to minimizing the adverse effects, in this targets specific antigen solely expressed by tumor cells, only target cancer and not the healthy cell population. According to a report of World Health Organization, more than 80% of world’s populations depend on traditional medicine for their primary health care needs (Farnsworth, 1994; Duraipandiyan et al., 2006). Plants have a long history of use in the treatment of cancer and it is significant that over 60% of currently used anti-cancer agents are come from natural source. Naturally occurring drugs that are part of the war against cancer include vinca alkaloids (vincristine, vinblastine, vindesine, vinorelbine), taxanes (paclitaxel, docetaxel), podophyllotoxin and its derivative (etoposide, teniposide), camptothecin and its derivatives (topothecan, irinothecan), anthracyclines (doxorubicin, daunorubicin, epirubicin, idarubicin) and others. In fact, half of all anti-cancer drugs approved internationally were either natural products or their derivatives and were developed on the basis of knowledge gained from small molecules or macromolecules that exist in nature (Cragg et al., 2005; Cr agg et al., 1997). In between 2001 and 2005, 23 new drugs derived from natural products were introduced for the treatment of disorders such as bacterial and fungal infections, cancer, diabetes, dyslipidemia, atopic dermatitis, Alzheimer’s disease and genetic diseases such as tyrosinaemia and Gaucher disease out of these 4 drugs have been approved as anti cancer agents. The approved anti cancer agents in 2002 doxorubicin, in 2002 estradiol, in 2004 cholorophyll and l- aspartic acid and taxol nanoparticles in 2005 (Butler, 2005). Three new drugs also introduced in 2007 originate from microbial sources for the treatment of cancer is marine alkaloid trabectedin, epothilone derivative ixabepilone and temsirolimus (Newman et al., 2003). Nature is an attractive source of new therapeutic candidate compounds as a tremendous chemical diversity is found in millions of species of plants, animals, marine organisms and microorganisms as potential anti-cancer agent (Bailly, 2009; Butler, 20 04; Bhanot et al., 2011). There were various biological mechanisms for controlling the cancer, out of it apoptosis and cell cycle inhibition are important one. Apoptosis is the process of programmed cell death (PCD) that may perhaps occur in multicellular organisms. In distinction to necrosis, which is a form of traumatic cell death that outcome from acute cellular injury, apoptosis generally confers advantages during an organisms life cycle. Biochemical events escort to characteristic cell changes (morphology) and death (Furuya et al., 1994). There are numerous pathways and signals lead to apoptosis, but there is only one mechanism that in fact causes the death of a cell (Meikrantz W, Schlegel; 1995). Subsequent to a cell receives stimulus, it undergoes planned degradation of cellular organelles by activated proteolytic caspases. A cell undergoing apoptosis shows a distinguishing morphology (Alenzi; 2004): The breakdown of the proteinaceous cytoskeleton caused by caspases which shown characteristic cell shrinkage and rounding. The cytoplasm appears dense, and the organelles emerge tightly packed. A process of pyknosis (a hallmark of apoptosis) in which chromatin undergoes condensation into compact patches in opposition to the nuclear envelope. The nuclear cover becomes broken down and the DNA inside it is split in a process known to as karyorrhexis. The nucleus breaks into a number of separate chromatin bodies or nucleosomal units as a result of the degradation of DNA. The cell membrane shows uneven buds known as blebs. The cell breaks together into several vesicles called apoptotic bodies, which afterward phagocytosed. Figure 1.1: Apoptosis in sequence: A) normal resting cell; B) cell volume is lost and chromatin clumped; C) blebbing process; D) chromatin collapsed to the margins of the nuclear envelope; E) nucleus clumped into a black hole; F) cell breaks down into apoptotic bodies; and G) apoptotic bodies ingested by macrophage. Cell cycle consists of two successive periods, that characterized by DNA replication and isolation of replicated chromosomes into two separate daughter cells. The cell cycle divided into five phases: G0, G1, S, G2, and M. Cell division, or cytokinesis, occurs through the M (mi ­tosis) phase, and is preceded by a prepa ­rative phase, or interphase, that includes G0, G1, S and G2 (Fig. 2). DNA replication occurs in a specific part of the interphase, the S (synthesis) phase, which is preceded by a gap called G1, where the cell prepa ­res for DNA synthesis, and followed by G2, during which the cell prepares for mitosis. Figure 1.2: A diagrammatic view of cell cycle indicating formation of two cells from one cell The vast preponderance of the cells are able to di ­vide but do so only when appropriate to re ­place damaged or dead cells. In fact, cells in G0 account for the major part of the non-growing, non-proliferating section of the human body, being essentially arrested in their growth. Cells in G0 can often be sti ­mulated to enter the cell cycle by external growth signals such as growth factors and hormones that bind to cell surface recep ­tors and then convey the signal from the plasma membrane to the nucleus, a pro ­cess known as signal transduction(Sherr, 1994; Ostsubo et al., 1995; Cerveira et al., 2012). The plant Aerva lanata L. belonging to family Amaranthaceae have been used for very long times in traditional system of medicine as diuretic and in lithiasis. Besides the traditional uses the plant were reported numerous pharmacological effects viz. diuretic (Udupihille and Jiffry, 1986), anti inflammatory (Vetrichelvan et al., 2000), anti-microbial, cytotoxic (Chowdhury et al, 2002), anthelmintic, demulcent (Pullaiah and Naidu, 2003), nephroprotective (Shirwaikar et al., 2004), anti-diabetic, anti-hyperglycaemic (Vetrichelvan and Jegadeesan, 2002; Deshmukh et al., 2008), expectorant, hepatoprotective (Manokaran et al., 2008), hypoglycemic, anti-hyperlipidemic (Krishnan et al., 2009), anti-parasitic and anthelmentic activities (Anantha et al., 2010), anti cancer activity was carried out against Daltons Ascitic Lymphoma (DAL) cell lines which show significant cancer control of the same (Rajesh et al., 2011). Beside this vast studies were carried out by various researchers to showing i mportance of Aerva lanata L. which includes finger printing chromatographic technique analysis of steroids, terpenoids, flavanoids and glycosides (Yamunadevi et al., 2011a; Mariswamy et al., 2011a; Yamunadevi et al., 2011b; Mariswamy et al., 2011b). As per previous studies phytoconstituens possessing anti-oxidant properties are believed to prevent or slow down the occurrence of disease such as cancer. In recent years, a large investigation on different classes of imidazo thiadiazoles has been done. Many of them were found to possess definite pharmacological activity. The fusion of a imidazole ring with a 1,3,4-thiadiazole nucleus give rise to a class of heterocyclic systems containing a bridgehead nitrogen atom known as imidazothiadiazoles. Imidazo[2,1-b][1,3,4]thiadiazole derivatives were first discovered in the early 1950s and, since then, the research work on heterocyclic system has led to significant developments in their chemistry and biology. The planar and rigid heteroaromatic imidazo[2,1-b][1,3,4]thiadiazole ring system have interesting physicochemical and biological properties, because of the presence of four hetero atom and two condensed heterocycles with different Ï€-conjugation. Imidazo[2,1-b][1,3,4]thiadiazoles ring systems have been extensively studied and so far, a variety of biological activities have been reported for a large number of their derivatives such as antitubercular, antibacterial, anticancer, anthelmintic, antifungal, anticonvulsant, anti-inflammatory, analgesic, antipyretic, local anaesthetic, diuretic, antileishmanial and herbicidal activities. In addition, they have been reported to selectively inhibit several therapeutic receptors and enzymes, extending their applications in modern drug design (Jadhav et al., 2008). So the present study was designed to evaluate the cytotoxic potential of the plant Aerva lanata L., isolation and characterization of phytoconstituents as well as preparation of their various novel derivatives as potential anticancer agents (Khazi et. Al., 2011).

Thomas Jeffersons Contribution to the Constitution Essay -- essays pap

Thomas Jeffersons Contribution to the Constitution The purpose of this paper is to give a brief chronological accounting of the writing of the Declaration of Independence by Thomas Jefferson. A short description of the structure of the Declaration of Independence will be included. The process was relatively fast, from the formation of the committee. The committee consisted of two New England men, John Adams of Massachusetts and Roger Sherman of Connecticut; two men from the Middle Colonies, Benjamin Franklin of Pennsylvania and Robert R. Livingston of New York; and one southerner, Thomas Jefferson of Virginia. In early June, the committee met as a whole and unanimously insisted that Jefferson draw up the declaration. Jefferson wrote that the other members of the committee "unanimously pressed on myself alone to undertake the draught. I consented; I drew it; but before I reported it to the committee I communicated it separately to Dr. Franklin and Mr. Adams requesting their corrections. . . I then wrote a fair copy, reported it to the committee, and from them, unaltered to the Congress." Jefferson's account reflects three stages in the life of the Declaration: the document originally written by Jefferson; the changes to that document made by Franklin and Adams, which resulted in the version that was submitted by the Committee of Five to the Congress; and the version that was eventually adopted. On July 1, 1776, Congress reconvened. The following day, the Lee Resolution for independence was adopted by 12 of the 13 colonies, New York not voting. Immediately afterward, the Congress began to consider the Declaration. Adams and Franklin had made only a few changes before the committee submitted the document. The discussion in Congress resulted in some alterations and deletions, but the basic document remained Jefferson's. The process of revision continued through all of July 3 and into the late afternoon of July 4. Then, at last, church bells including Paul Revere's bell, rang out over Philadelphia; the Declaration had been officially adopted. The Declaration of Independence is made up of five distinct parts: the introduction; the preamble; the body, which can be divided into two sections; and a conclusion. The introduction states that this document will "declare" the "causes" that have made it necessary for the American colonies to leave the B... .... Because of his absence in Europe, Jefferson had no direct part in the framing or ratification of the Constitution of the United States. The most notable achievement of Jefferson's first term as President (1800) was the purchase in 1803 of Louisiana from France for 15 million dollars. (see Lewis and Clark). During his second term Jefferson encountered greater difficulties. One of the domestic problems was the Burr-Conspiracy, with the former vice president on trial for treason. Jefferson was succeeded as president in 1809 by James Madison. During the last 17 years of his life, Jefferson remained in Virginia. As the 'Sage of Monticello' he engaged in a rich correspondence with John Adams and others. Jefferson's last great public service was the founding of the University of Virginia in 1819. He died at Monticello on July 4, 1826 on the 50th anniversary of the Declaration of Independence.

Amblyopia Essays -- Medicine Medical Eye Papers

Amblyopia This paper provides a brief description of amblyopia and discusses current research regarding the motion pathway in individuals with amblyopia. Amblyopia is a condition in which visual acuity in one eye is greatly reduced. It is caused by lack of stimulation or disuse during visual development (Rose, 1998). Because the eye is not fully developed at birth (Jarvis, 1992, as cited in Rose, 1998), infants need stimulation to complete the visual neural pathway. When one or both eyes are inhibited, for example due to misalignment of one eye (strabismus) or a large difference in refractive power between two eyes (anisometropia), the neural pathway for the inhibited eye develops abnormally, or does not develop at all. At approximately six years of age eye development is complete (Stager, 1990, as cited in Rose, 1998). Before visual development is complete amblyopia can be treated. If it is caught and treated at an early age, normal vision can be preserved (Rose, 1998). There are several types of amblyopia. Researchers must be aware of the various types of amblyopia because the effects for each are not always consistent. Strabismic amblyopia is caused when the two eyes are out of alignment due to weak musculature. Anisometropic amblyopia is a result of a large difference in refractive power of an individual's eyes. Another form of amblyopia results when visual information does not reach the retina. This is called stimulus deprivation amblyopia. Meridional amblyopia is a result of the diffused images caused by astigmatism. Researchers often discover that there are differences between groups of amblyopes based on type. For example, Levi and his colleagues (1994) discovered differences in vernier acuity between anisomet... ...9-1944. Hess, R. F., & Anderson, S. J. (1993).
