Islam Guide Essay Example | Topics and Well Written Essays - 750 words

Islam Guide - Essay Example A review of the five pillars of the religion suggests that belief and witness, i.e. the Shahada, daily prayers (five times a day), almsgiving (Zakat), fasting during Ramadanm and pilgrimage to Mecca (Hajj) are basic to Islamic religion. Significantly, the author commences the chapter on Islam with a detailed description of the life and works of the Prophet Muhammad, according to which the Prophet Muhammad always denied having any superhuman powers. As the Qur’an describes him, the Prophet Muhammad was a human like anyone else, and he was just a servant of the God to whom revelation has come. Significantly, the Prophet Muhammad made only a single claim about his miracles: that he had received the Qur’anic revelations in an extraordinarily eloquent and pure Arabic. â€Å"Nevertheless, all who saw the Prophet remarked on his touching physical beauty, his nobility of character, the fragrance of his presence, his humility, and his kindness. In his devotion to God, he quietl y endured poverty so extreme that he tied a stone over his stomach to suppress the pangs of hunger.† (Fisher, 337) Therefore, Living Religions by Mary Pat Fisher provides a compelling study resource on the historical development and major teachings of the Islamic religion and the readers are able to recognize how this religion has evolved into contemporary beliefs and practices. It is pertinent to realize that the opening section of the chapter on Islam in Living Religions by Mary Fisher deals with the history concerning the Prophet Muhammad followed by the teaching story of the humility of the Prophet. In the teaching story, the readers are provided with a convincing illustration of how the humility of the Prophet was a model to his followers. In the next section, â€Å"The Qur’an†, the author maintains that it is the revelations that the Prophet received, rather than the Prophet himself, which is at the heart of Islam, and the Qur’an outlines the message s he received over a period of twenty three years. â€Å"At first they were striking affirmations of the unity of God and the woe of those who did not heed God’s message. Later messages also addressed the organizational needs and social lives of the Muslim community†¦ Recitation of the Qur’an is thought to have a healing, soothing effect, but can also bring protection, guidance, and knowledge...† (Fisher, 338) Thus, the author offers a forceful and comprehensive illustration of the history of the religion based on its teachings and principles as given in the Qur’an. In the next section of the chapter, Mary Fisher deals exclusively with the central teachings of the Islam and she covers all the major aspects of the Islamic principles. Thus, the author talks about ‘the oneness’ of God and humanity, prophet-hood and the compass of Islam, human relationship to the divine, the unseen life, and the last judgment. According to the author, there is great similarity between the essence of God and the human nature, and they are united to each other. Mary Fisher also establishes that prophet-hood is the essential characteristic of Islam, and the Prophet Muhammad is the unquestionable leader of the religion. In this section of the chapter, the author makes a reflective analysis of the human relationship

Far from the madding crowd Essay Example for Free

Far from the madding crowd Essay Roles of women in the Victorian times were very limited compared to now. They were expected to be house wives, and never expected to have an opinion or point of view. They were never in control of anything and everything was decided by men. They were usually expected to take care of everything in the house including looking after children. They were very much expected to be women whose life revolved around the domestic sphere of the home and family. However, this role was challenged by Queen Victoria In the novel Far From the Madding Crowd you see Bathsheba and Fanny breaking the norms expected from women in Victorian times. Sometimes these norm-breaking actions would result in a sever consequence depending on how bad the norm-breaking was. However, sometimes these limits which exist were ignored, but no penalty was paid. In chapter 42 Bathsheba opens the coffin in which Fanny and her baby lay. Here you can see an example of a woman crossing the barrier of what was expected from her, but no penalty being paid. She is very insecure as weather to open the coffin or leave it closed. If I could only look in upon you for one little minute I should know all She finally does open the coffin and is slightly relieved that her tension and suspense has come to an end. It was best to know the worst, and I know it now. She is in a lot of pain, because she now knows that it was the women that Troy loved. She realises that it is his baby and is shocked when Troy says to her that he will never love her like he loved Fanny. Bathsheba also realises that Troy has slept with Fanny out of marriage, which was a very unacceptable action in Victorian times. She does not wish to pursue or debate with Troy about what he has done, because there are risks of other people finding out and this would bring shame to her self-image. The consequences of Troys actions would mean that people would look at them badly and want nothing to do with them. In a way, Fanny paid the price for a highly thought sinful act, and through death. Many Victorian readers wouldve been shocked at Bathshebas actions when she opens the coffin and also with Troys actions. Bathsheba is obviously troubled and disturbed; otherwise she would never have opened the coffin. You can see that she is showing her true emotions and in Victorian times women never showed their true emotions. Bathshebas actions for opening the coffin would not have been a very severe punishment but would be frowned upon by many Victorians. In chapter 13, the expected roles of women are transgressed when Bathsheba and Liddy play the game of the Bible and key. Did you ever find out, miss, who you are going to marry by means of the Bible and key? Many Victorian women would think it a very foolish game to play, therefore, not expected from women. This chapter is an example of a woman crossing the barrier of her expected role, but nothing happening and therefore no consequence. In chapter 11, fanny pays a visit to Troy; however, she travels a very long distance to do this. It was very unusual in Victorian times and nowadays that a woman should travel for miles and miles by foot to visit their loved ones. This wasnt considered very lady-like, and was looked as desperate. It could also have been seen as chasing him around, therefore not being a proper Lady. To make matters worse, Troy dismisses her abruptly which shows a lot of disrespect for Fanny. But Fanny doesnt acknowledge this and we can see that she is a weak character. There was a tone in the woman which is not that of the wife, and there was a manner in the man which is rarely a husband. Fannys actions may also have come down to her social class. Her ways of thinking may have also been completely different to that of an upper class. However, the boundaries of what was expected from women was the same throughout social class. But some may have broken these boundaries with no consequence. You can see now that if the boundaries are taken too far the consequences are drastic and sever. However, sometimes they are ignored or they are hidden. Fanny ignored these boundaries and paid the penalty. Bathsheba did step over the line, but never did ignore the extreme limitations. The women in the novel are defined by how they are seen to everyone else. Some Victorian women would not abide by the rules that were set for them, and some would, either out of fear of what would happen to them if they didnt or they didnt want to feel sinful.

Overview And Causes Of Pica Disorder Biology Essay

Overview And Causes Of Pica Disorder Biology Essay Pica Disorder is the affliction that causes people to have a sudden urge to consume non-food related items (1). This disorder has baffled scientist for decades, and research has yet to come up with a clear reason or cause (1). Pica disorder can be found in literature as early as Hippocrates, and has been classified by many ancient scholars during the middle ages and Renaissance times (1). Many explorers, missionaries, and colonist have also written accounts about pica disorder in their journeys (1). Many of these early descriptions placed pica disorder as an intense desire to consume non-food related items, and has been described as a cultural phenomenon with no physiological cause(1). The word pica comes from the Latin word Pica pica which is the name of the magpie, a bird that is described to have an erratic appetite (1). Other names include cachexia Africana (named by doctors who took care of the African slaves), citta, mal destomac, and malacia (1). Pica disorder is prevalent among pregnant women and young children because they are the most biological vulnerable, and can also be found in people that are undergoing renal dialysis, have celiac disease, and those who have a red blood cell defect such as sickle cell anemia (1). The disorder can cause many different affects on the body with both positive and negative results (1). Some negative effects include: metal poisoning, damage to internal organs, and some weight gain (1). Positive effects may include: providing important micronutrients that the body lacks (Fe, Ca, or Zn), possible relieving stress on the gestational tract, and preventing harmful pathogens and bacteria from entering the blood stream (1). Several explanations have been provided to explain what causes pica disorder such as: psychological stress, dyspepsia, general hunger, protection against toxins and pathogens, and a side affect of iron deficiency which can cause anemia (1). In medical literature the definition of pica is, the craving and purposive consumption of substances that the consumer does not define as food with symptoms lasting longer then one month. (1). This clarification indicates that pica cannot be classified as the accidental ingestion of dirt or other non-food items, and the individual must voluntary consume the substance (1).The urge for pica can be compared to the addiction of tobacco, drugs, or the consumption of alcoholic beverages (1). The list of pica substances is countless, but a few of the major items include the consumption of: dirt, raw starch (uncooked pasta), ice, paper, chalk, eggshells, coffee grounds, matches, and in extreme cases needles or other sharp pointed items (1). Body Major Forms of Pica Disorder The consumption of dirt, clay, and chalk for the nutritional value that they might contain is called geophagy (1). This practice is prevalent among pregnant women, and in some communities might reach up to 60% of the population (1). The soil can be prepared by baking or frying, and the amount of dirt ingested ranges from 20-40g, and can range from consuming pieces of pottery, or eating beans that have a high concentration of dirt found in them (1). Most of these items include some type of clay in them, which contains a compound called kaolin, which is ingredient found in some anti-diarrhea medications (1). Another alternative to eating soil or clay is found in the consumption of other non-nutritional foods such as raw starch which is known as amylophagy (1). Most of these starches come in the form of raw foods such as uncooked rice, pasta, and starchy rubbers (1). The consumption of these starches ranges from a couple of grams per day to 1kg (1). One other major form of pica disorder can be found in pagophagy which is the consumption of ice (1). Unlike the average person that might suck on an ice cube or two, someone who practices pagophagy consumes several glasses of ice a day (1). Several Hypotheses There are several hypotheses that explain the environmental factors that might cause the onset of pica. These hypotheses can be broken down into three sub-categories: hunger, micronutrient deficiency, and protection against toxin (8). Researchers, however, have found little to no information on the genetic basis or mechanism that is associated with pica disorder. This lack of data is associated with researchers not having acknowledged that pica disorder is prevalent among many populations of the world today, and the belief that pica is just a mental ailment (8). Conducted Research on Anemic properties and Pica Disorder The main hypothesis concerning pica disorder is the association between pica and anemia (1). Some researchers have hypothesized that pica is a symptom which is developed when one becomes anemic (1). In two different studies, pregnant women were tested for several different variables. In the first study, researchers took a group of 823 pregnant women from Turkey and analyzed their relationship between anemia and pica (5). The second study consisted of pregnant women found in Tanzania that were tested to see picas involvement with immunodeficiency diseases (HIV), iron deficiency, soil transmitted helminth infections such as malaria, and the potential danger of infection of parasites (7). The demand for iron in a pregnant woman is much greater then the average human because of the increasing amount of blood cells needed for the mother and the fetus (7). The lack of iron can result in iron-deficiency anemia, abortions, false labors, and multiparity (5). In a worldwide study it was found that 20% of all maternal deaths resulted from anemia, and can also lead to premature births, underdeveloped infants, increased infant fatality, and a decrease in fertility (5). In the study done in Turkey, researchers were able to find that out of the 823 pregnant women studied, 1 out of 10 exhibited pica behavior (5). Most of these women were illiterate and were in a lower social class that resulted in less consumption of animal protein, and the lack of funds to take iron supplements during their pregnancy which resulted in deficient amount of iron, folate, and vitamin B12 during their pregnancy (5). In the study done in Tanzania, researchers found that 82.6% of the women studied had anemia where about 29% ate soil on a regular bases (7). Those that consumed soil were 75% more likely to have severe anemia when compared to those that didnt (7). Women that showed signs of iron deficiency (such as a decrease number of hemoglobin) were also more likely to consume pica substances (7). T here was no correlation between HIV and geophagy, and women that had malaria did not consume soil which could be a result of soil containing traces of iron which makes the conditions of malaria worse (7). The amount of Ascaris lumbricoides (round worm) found in the pregnant women was much higher in those who practiced geophagy (7). Geophagy became more prevalent as the pregnancy progressed (7). This could be the bodys response of supplying more iron to form more hemoglobin (7). Another purposed hypothesis is that when an individual practices in consuming non-food related items this can result in anemia (1). This hypothesis states that the intake of non-nutritional elements does not result in a positive result or a decrease in this deficiency (1). The mechanism behind this phenomenon is found to be caused by tissue enzyme deficiency and this includes Fe and Zn deficiencies which play a role in appetite regulating brain enzymes (1). In one study, three subjects were tested that exhibited different types of pica (4). One subjected consumed at least two super-sized McDonald soda cups filled with ice a day which resulted in heavy bleeding during her menstrual cycle (4). Another subject would drink iced water three to four times a day which resulted in the formation of colonic polyps which caused bleeding (4). The third and final subject would chew on rubber bands with a specific color and diameter (4). All three of the individuals were mentally stable, and had no history of mental ailments (4). After treated with iron supplementation, one subject was able to stop their pica condition while the other two were still undergoing treatment (4). It has been suggested that the reason why individuals that have developed pica eat ice in an abnormal amount is because glossal pain on the tongue can develop because of iron deficiency, and the ice actually soothes the pain (4). It has also been suggested that stress that is formed in the upper gastrointestinal tract (such as heartburn or nausea) brings on the urge of consuming pica elements (1). This is because some pica elements contain high traces of alkaline which can act a suppressor and reduce the gastric pH in the gastrointestinal organs which would reduce the pain induced by heartburn or nausea (1). This however does not take into account for the individual that chewed on rubber bands (4). In another case report, a 22-year old African woman was diagnosed to have severe anemia (6). The woman had complained of immense fatigue, and it was found that she had been consuming a stone that was high in kaolinite and quartz for the past 15 years (5). After removing traces of the stone in her body and providing iron supplements, the woman was able to recover from her sever anemia, and a check up 3 months later showed a satisfactory blood count and stable iron levels (6). A possible reason to why this stone made the woman develop severe anemia is because of the high levels of kaolinite found in the stone (6). Kaolinite is a compound that is able to absorb concentrations of Fe2+ and Fe 3+ in the duodenum, which is where iron is absorbed by the body (6). This could have caused her to develop a deficiency in iron which could have led to her having severe anemia (6). In many cases of pica, iron deficiency or anemic properties are present in the individual (1). There have been positive results that show livestock that have developed iron deficiency and have engaged in pica activity have shown improvement in their iron deficiency (1). However, sodium is the only known nutrient that is craved in humans, and some data shows that most pica substances have little to no iron in them except for soil, which the iron content of is less known although some acid base tests have been taken which resulted in some pica substances containing nutritional elements such as Fe, Zn, Cu, and Ca (1). These tests however do not take into account the pH of the intestine, and the site of these nutritional elements such as Fe (1). Overall this hypothesis is an intriguing one, but does not have any current data that suggests that consuming pica elements actually help elevate iron deficiency or other nutritional deficiencies (1) Pica used as protection against pathogens and toxins A recent hypothesis that has come up in the scientific community is that pica substances are consumed to protect against harmful chemicals and pathogens (1). Clay is shown to exhibit toxin-binding properties, and kaolin (found in some clay) is an active ingredient found in some anti-diarrhea medications (3).These toxins can come from plants, which produce toxins as a protective measure against predators (1). These toxins can cause dizziness, muscle pains, and other unwanted side effects (1). Other chemicals can enter food via bacteria such as Escherichia coli and Staphylococcus aureus (1). Viruses and parasites can also enter the body and cause damage (1). In a study done with rats, the rats were injected with a chemotherapy agent (cisplatin), and then given doses of kaolin (3). The rats that were given kaolin showed less acute symptoms then the rats that were injected with cisplatin which exhibited a decrease in appetite, and weight loss (3). Kaolin could have played a role in decre asing the anxiety felt by the rats, and possibly sped up the recovery process (3). The mechanism on how clay and kaolin work on the body is still a mystery, and does not solidify the hypothesis that pica substances play a role in elevating pain from toxins or other chemicals (3). Conclusion Although pica disorder has been known since the time of Hippocrates, it is still a mystery to many researchers (1). The next step to further the knowledge about pica is to take a multidisciplinary approach, and to shift the idea of pica just being a mental ailment to pica also playing a physiological role in individuals (8). It is not fully understood to whether pica plays a role in the onset of anemic properties or if pica is a side effect of anemia (8). There is also the possibility that pica can contribute to the prevention or relief of toxins and pathogens from entering the blood stream (1). Although pica is not fully understood, it still must be taken seriously, as the effects are still not fully understood and could result in many complications that can lead to suffering for individuals that experience pica symptoms (1).

The Physics of Roller Coasters :: Physics

A roller coaster is a thrill ride found in amusement and theme parks. Their history dates back to the 16th century. It all started in Russia, with long, steep wooden slides covered in ice. The idea then traveled to France. Since the warmer climate melted the ice, waxed slides were created instead, eventually adding wheels to the system. The first roller coaster in which the train was attached to the track was in France in 1817, the Russess a Belleville. The first attempt at a loop-the loop was also made in France in the 1850s. It was called the Centrifuge Railway. However, government officials quickly diminished the idea when the first accident occurred. Inventors since then have continued to capitalize on people’s love of a great thrill, always trying to make them bigger, faster and scarier! â€Å"Even though roller coasters propel you through the air, shoot you through tunnels, and zip you down and around many hills and loops, they are quite safe and can prove to be a great way to get scared, feel that sinking feeling in your stomach, and still come out of it wanting to do it all over again (1).† Thanks to the manipulation of gravitational and centripetal forces humans have created one of the most exhilarating attractions. Even though new roller coasters are created continuously in the hope to create breathtaking and terrifying thrills, the fundamental principles of physics remain the same. A roller coaster consists of connected cars that move on tracks due to gravity and momentum. Believe it or not, an engine is not required for most of the ride. The only power source needed is used to get to the top first hill in order to obtain a powerful launch. Physics plays a huge part in the function of roller coasters. Gravity, potential and kinetic energy, centripetal forces, conservation of energy, friction, and acceleration are some of the concepts included. â€Å"A roller coaster is essentially a gravity-powered train (2).† Gravity is the weakest of the four physical forces, but when it comes to roller coasters, it is the dominant one. It is the driving force and what accelerates the train through all the turns and twists. Gravity is what applies a constant downward force on the cars. The deceleration or acceleration mostly depends on the inclination of the angle relative to the ground. The steeper the slope is, the greater the acceleration, and vice versa.

White-Only Scholarship Controversy :: Diversity Equality Racism Essays

Diversity, a word often heard growing up. In high school diversity was an issue that was pushed repeatedly. I attended a school that had a student body of over 2000 students, in which diversity was not really an issue. As time passed I found that diversity affected my life more and more. As college neared filling out applications became more of a ritual, and I found that by being born into a white middle class family would hinder my financial status rather than help it. Recently an article appeared in the Iowa State Daily, which addressed the issue of a white-only scholarship. In addition to the scholarships offered to members of the minority races, a scholarship should be offered to the members of the decreasing majority. Whites or Caucasians make up a group just as Native Americans, blacks, and Hispanics do. The one thing that separates whites from these other groups besides skin color is the fact that for each minority group, there are several scholarships that pertain to each. As a nation we have placed a great deal of emphasis on making sure the minorities are getting equal opportunities, but we forget that there are members of the Caucasian decent that need assistance as well. Most times minorities are the ones that need financial assistance in a college situation, but we have forgotten that there are white families that have grown up in the same neighborhood as these individuals, who also need financial assistance. This is why the idea of a white-only scholarship is not so unrealistic. A group of students attending Roger Williams University have created a Whites-only scholarship to initially protest affirmative action. This protest however has snowballed into the real thing. This protest has now become a $250 scholarship available to only white students. This award shows America that whites are becoming the minority, and no matter how much we fight it, it is going to become a reality sooner or later. This then opens America’s eyes and shows them that by being a minority there are more opportunities for financial aid based on skin color than there are for whites. This said, there should be at least one scholarship for just whites to counteract the many minority scholarships available to other races. â€Å"Many people think that coming from a white background you’re automatically privileged, you’re automatically rich, and your parents pay your full tuition.
