Bimetallism Definition and Historical Perspective

Bimetallism Definition and Historical Perspective Bimetallism  is a monetary policy wherein the value of a currency is linked to the value of two metals, usually (but not necessarily) silver and gold. In this system, the value of the two metals would be linked to each other- in other words, the value of silver would be expressed in terms of gold, and  vice versa- and either metal could be used as legal tender.   Paper money  would then be directly convertible to an equivalent amount of either metal- for example, U.S. currency used to explicitly state that the bill was redeemable â€Å"in gold coin payable to the bearer on demand.† Dollars were literally receipts for a quantity of actual metal held by the government, a holdover from the time before paper money was common and standardized. History of Bimetallism From 1792, when the  U.S. Mint was established, until 1900, the United States was a bimetal country, with both silver and gold recognized as legal currency; in fact, you could bring silver or gold to a U.S. mint and have it converted into coins. The U.S. fixed the value of silver to gold as 15:1 (1 ounce of gold was worth 15 ounces of silver; this was later adjusted to 16:1). One problem with  bimetallism  occurs when the face value of a coin is lower than the actual value of the metal it contains. A one-dollar silver coin, for example, might be worth $1.50 on the silver market. These value disparities resulted in a severe silver shortage as people stopped spending silver coins and opted instead to sell them or have them melted down into bullion. In 1853, this shortage of silver prompted the U.S. government to debase its silver coinage- in other words, lowering the amount of silver in the coins. This resulted in more silver coins in circulation. While this stabilized the economy, it also moved the country towards  monometallism  (the use of a single metal in currency)  and the  Gold Standard. Silver was no longer seen as an attractive currency because the coins were not worth their face value. Then, during the  Civil War, hoarding of both gold and silver prompted the United States to temporarily switch to what’s known as â€Å"fiat money.† Fiat money, which is what we use today, is money that the government declares to be legal tender, but thats not backed or convertible to a physical resource like metal.  At this time, the government stopped redeeming paper money for gold or silver. The Debate After the war, the  Coinage Act of 1873  resurrected  the ability to exchange currency for gold- but it eliminated the ability to have silver bullion struck into coins, effectively making the U.S. a Gold Standard country. Supporters of the move (and the Gold Standard) saw stability; instead of having two metals whose value was theoretically linked, but which  in fact fluctuated because foreign countries often valued gold and silver differently than we did, we would have money based on a single metal that the U.S. had plenty of, allowing it to manipulate its market value and keep prices stable. This was controversial for some time, with many arguing that a â€Å"monometal† system limited the amount of money in circulation, making it difficult to obtain loans and deflating prices. This was widely seen by many as benefiting the banks and the rich while hurting farmers and common people, and the solution was seen to be a return to â€Å"free silver†- the ability to convert silver into coins, and true bimetallism. A Depression and a  panic in 1893  crippled the U.S. economy and exacerbated the argument over bimetallism, which came to be seen by some as the solution to all of the United States’ economic troubles. The drama peaked  during the  1896 presidential election. At the National Democratic Convention, eventual nominee  William Jennings Bryan  made his famous  Ã¢â‚¬Å"Cross of Gold†Ã‚  speech  arguing for bimetallism. Its success gained him the nomination, but Bryan lost the election to  William McKinley- in part because scientific advances coupled with new sources promised to increase the supply of gold, thus alleviating fears of limited money supplies. The Gold Standard In 1900, President McKinley signed the  Gold Standard Act, which officially made the United States a monometal country, making gold the only metal you could convert paper money into. Silver had lost, and bimetallism was a dead issue in the U.S. The gold standard persisted until 1933, when the  Great Depression  caused people to hoard their gold, thus making the system unstable; President Franklin Delano Roosevelt  ordered all gold and gold certificates to be sold to the government at a fixed price, then Congress changed the laws that required settlement of private and public debts with gold, essentially ending the gold standard here. The currency remained pegged to gold until 1971, when the â€Å"Nixon Shock† made then U.S. currency fiat money once again- as it has remained since.

But if theres ever a time when its absolutely vital, its when addressing sensitive matters. Gordon Brown knows this now better than anyone. At a time of year when everyone is particularly conscious of the lives and lot of soldiers, it is especially mortifying that he apparently sent out a handwritten condolence note with misspellings, including of the late young mans name. Whether its your unfortunate duty to be penning a letter denying a loan, rejecting a proposal or giving someone their notice, you must remember that the recipient will probably already be on the defensive. Any typos or unchecked errors will just seem like insult piled on top of injury. So, be it in the spirit of not burning bridges, of good press, or merely the milk of human kindness get the details right.

Week 1 Discussion HUM 112 Assignment Example | Topics and Well Written Essays - 250 words

Week 1 Discussion HUM 112 - Assignment Example Consequently, there are several well-known painters when it comes to Baroque style paintings representing not only the era of the period but also the flamboyant and rich culture. Rembrandt van Rijn (1606-1669) created a portrait painting of a young woman. Emphasis of the portrait is placed on the various white accessories such as lace cuffs, gloves, coifs, and the large millstone ruff. In another different painting from the same period, describing the details of the woman costumes, the significance was accorded to the overall portrayal and appearance of a rich heritage. Moreover, another baroque painting by Portrait of Marchese Spinola, the female fashion is seen to have changed so much from 1630s and 1660s (Hill, 2011). The whole silhouette changed, from the elevated wasted gowns of 1630s to that of long and slender wasted in 1660s. Paintings that have been viewed clearly provide more details when observed keenly. They do not just represent the painter, but also the particular message being conveyed by each of the art viewed within that period. The baroque paintings are not just distinguished by the rare presentation of the surrounding, but also the messages that are successfully presented by the painters. Baroque style paintings remind me of Christian film and videos. Nonetheless, the work that distinguishes the baroque style paintings is contradictory and stylistically complex. Moreover, the desire of evoking emotional states through appealing to the senses in dramatic ways underlies its very manifestations (Hill, 2011). The qualities associated with baroque include sensuous, drama, grandeur, emotional, vitality, and tendency to blur the distinctions between various

The Strange Case of Dr. Jekyll and Mr. Hyde by Robert Louis Essay

The Strange Case of Dr. Jekyll and Mr. Hyde by Robert Louis - Essay Example Stevenson uses an innovative approach to portray the human soul as a battlefield for an â€Å"angel† and a â€Å"fiend† who are foes in a battle for the possession of the human soul. Every human being contains these opposite forces within him, an alter ego that hides behind a social and polite everyday facade. Jekyll asserts that â€Å"man is not truly one, but truly two,† that one is never black nor white and that the situation at hand always brings out more of one side or the other. Jekyll’s potion that was initially meant to separate and purify these two elements, the angel from the fiend, only manages to bring out the dark side into being. Hyde emerges from the depths of Jekyll, but he brings forth no angelic counterpart. It is left to be argued whether or not this role of the angelic counterpart is left for Jekyll. It is more than obvious that his demeanor is outright moral and decent, and he enjoys the repute of a benevolent, well-mannered and genial man, yet he never embodies the virtue of good equally as Hyde embodies the very opposite from it. He merely portrays civilized behavior and morals, leaning towards good. In his bold and philanthropic efforts, he takes it upon himself to purify the good, but he ends up liberating the darkness from the shackles of conscience.

Outcasts united written by Warren St. John Essay

Outcasts united written by Warren St. John - Essay Example The book has been published in the United States of America by Spiegel & Grau in New York. Characters, Plot & Summary In his masterpiece, John talks about Clarkston, a remote place set aside for providing shelter to the refugees emerging from different corners of the world, from Iraq and Afghanistan to Liberia and Sudan, from Congo and Burundi to Bosnia and other nations. This downtown outside Atlanta, which was once white dominated region, is now a blend of different cultures, religions and colors. â€Å"The local high school in Clarkston, one all white, now had students from more than fifty different countries. Cultures were colliding in Clarkston, and the result was a raw and exceptionally charged experiment in getting along.† (John: 9) The UNHCR has chosen families from the Middle East, Africa and Southeast Asia for offering resettlement in Clarkston. Almost all of these families have landed here empty handed with the backup of government’s assistance for just three months post which they were expected to earn their own livelihood. Leaving one’s own native land and starting a life from scratch on a foreign land, amongst diverse cultures, hurdles were but obvious. But what is inspiring is that this very common state of the uncommon refugees brings them together to form a community of their own. The motto â€Å"Small town †¦. ... The story then progresses with the mentorship of this lady coach who makes these boys face the unpredictable challengers for themselves as well as their parents thereby wiping out all the differences amongst themselves. This Muslim lady in the Deep South had the will and courage to earn the small town and its new dwellers an identity. As one moves further, one can overtly get to know the impeccable efforts of the Middle Eastern lady who leaves no stone unturned to keep the boys away from the streets. The indomitable spirits of these refugees who call themselves â€Å"Fugees† is truly admirable. Their love for soccer accompanied with their bondness after a tight struggle of differences be it of color (black or white), religion (Muslim or Christianity) or language, reveals the strength of action and determination. Even without fancy cleats and embroidered soccer bags which their competitors possessed, this energetic team was dangerously tough for all other teams in the league. T he author nicely portrays the longing of the Fugees for the sense of belonging in their new homes. The discipline that Mufleh brings into the lives of her players might seem brutal at times, but is the bringer of positive results also. Her statement, â€Å"rules, my drills, my way† is something to learn from. (John: 267) Such is the popularity of the story that Outcasts United has been considered by Universal Studios. Conclusion Reading Outcasts United was good. By portraying the true story of the refugees and Mufleh, John has gracefully highlighted a new community which deserves to be treated as a significant part of the existing community. What I found most interesting in the entire book was the

Rituals In Religion For Ancient Rome Theology Religion Essay

Rituals In Religion For Ancient Rome Theology Religion Essay Religion can be simplified as a belief or the faith that is believed to aid people in the problems of life. The beliefs are organized in relation to humanity and the spiritual world. In every religion in the world there are narrative, symbols, traditions and even histories that explain the religion belief. Each religion tries to give a meaning to life as well as explain the origin of life and the universe. Religions matters include rituals, sermons and even commemoration which differ from one religion practice to the other (Adkins Roy, 274). They define this through their religious scriptures and holy places. Religion in Ancient Rome was so intense the Romans regarded it, as theirs. They (Romans) also regarded themselves highly in terms of religion. They even attribute their success in the world to the unity and good relation with their gods. Historically, their leaders claimed to be in direct negotiations with their gods. This in turn made religion among Romans to be a hugely significant aspect. They did all they had to be identified religiously. The leaders were supposed to identify in terms of religion, and they mostly used to be the pontiffs. There is acutely much in the religion of the Romans and the way they carried out their religious practices. The Roman religion was something that was termed as practical and contractual. It was mainly based on knowledge, and the practice of prayer rituals and the sacrifices offered and not based on faith. Rome is thought to be the source of the religion particularly the catholic practice. However other communities in the world had their own beliefs and practices not to mention their religions. However, the Roman Empire is thought to have contributed to significant changes in other religions of the world. What is the impact of religion and rituals in the ancient Rome? The godà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s and goddesses of Rome were identified with the cities and lives in each of the cities. The gods lead people as they were consorted before any actions. They were offered sacrifices frequently in order to please them. The roman religious attitudes resulted to the state cult and influence on political as well as military events. Family heads were responsible in overseeing domestic rituals and players. In the Roman Empire, the issues to do with the religion were left in the hands of the state officials and not in the individuals care. During the ancient times in Rome there existed a number of religious posts where each one of them served a pivotal role in the organization (Rupke, 259). The early times in the roman religion, it was based on spirits and the people did not build mythologies like their Greek counterparts as they believed everything had spirit. The spirits were held responsible for any good or evil in the communities. This obliged th e Romans to keep the spirits happy through various worshipping and sacrifice offering to them. Proper performance of the rituals and the sacrifices was believed to keep the gods happy. The Romans had a practical approach to the issue of religion. This explained why they had a number of gods rather than believe in one powerful god. Their religion was not centrally originating or believed but was comprised of a number of rituals, superstitions and taboos. There also contained different traditions which were collected from different sources over time. Their religion was less spiritual but a relationship with external forces that they believed controlled their existence and well being. Various Origins are credited for the roman religion. Several gods and goddesses were bled for several religious influences. Many of these came via the Greek colonies from the southern part of Italy. Other had their origin from the old religions that existed in society. For example, they had a god known as Diana which was believed to originate from Latin. Many of the rituals and the sacrifices made by the Romans were done as per their belief that the gods and the goddesses needed to be pleased. They also prayed for them to have the good fortune in their actions. Therefore, sacrificial offerings were made to the roman gods. These sacrifices were specific and were highly respected in the society as well as highly ritualized. For example, the sex of animal sacrificed was supposed to correspond with the sex of the goddess or the gods to whom the sacrifice was meant for (Browne, 86). The upper gods were offered white animals and the black ones were offered to the underworld gods. There were public, and even private offerings done statues were erected along the streets and market places. Some of the sacrifices made during games, ceremonies, altar among others. The five posts (Vestal virgins, pontiffs, Haruspex, Flamens Augurs) formed the basis for the sacrifices made by the Romans. Each of the post had a meaning in the Roman Empire. Pontiff s were the advisors to the magistrates the Haruspex was a priest who was greatly regarded in the society and he was for predicting the future. The Augars were used to tell whether the gods were in support of any of the government action. The vestal virgins were never to let out the flame as their duty was to guard the sacred fire. They were also supposed to bake the sacred salt cake for use in a number of ceremonies. They were supposed to remain virgins (Browne, 90). The Roman calendar contained months and corresponding festivals. I.e. each month had festivals that were in honor of their gods. They were comprised of sober, joyful and dignified events. For example in the month of February, people were given 9 days to worship their dead ancestors, at this time businesses were closed, and no marriages were allowed as well as closing of the temples. A number of festivals followed where each occasion had a meaning to the Romans. Religion in the ancient roman religion was incorporated together with the state in their belief system. For example, a sacrifice to the gods or an oath was legally binding. Despite the strict following of religion by the Romans, the survival of religion depended on renewal and also affirmation of their beliefs as time changed as also the social and the attitude changes. Their beliefs were on unconnected traditions where many of them came from Greek rather than Italian foundation. As they lacked core basis of their beliefs, other religions found it easy to establish themselves in the Rome. Some of the cults that managed to find their way into Roman Empire are religions such as the goddess Cybele and Isiris and Osiris from Egypt (North, 44). The initial roman religion continued to be undermined by the increasing impact of the Greek philosophy such as the stoicism which in itself taught that there was a single god. As I summarize, it is clear that the issue of religion in the ancient Rome was rather municipal and not personal. When this is compared to todays Christianity, it is different. This is because in Christianity god is worshiped from the peoples love and the trust they have for him rather than fear as shown by the Romans in the ancient times. The roman took part in offerings to their gods as well as making sacrifices. They went ahead and established family religious practices which were carried out in their homes. They had a number of god and goddesses whom they believed were responsible for watching and take care of them if they treated them in accordance. This explains why the Romans performed the rituals and the actions they did. The roman religion was defined by a set of rules and rituals that were performed in the community. As seen, the religion community, tradition and the community prescribed the rituals that were to be performed at any given time. As time moved on there were changes and people could choose the religious group to follow from different groups that existed. The groups came in between the time of Caesar and Augustine who ruled in the 4th and 5th centuries respectively. The impact of religion in the Roman Empire was felt all over the nation. However, from the incoming religious believes the Romans adopted a number of them and followed them. This left the Romans divided as they did into have their own established religion (Warrior, 7). In the ancient times, religion was interconnected with politics, and it is the politicians who taught the religion as it was treated to be a public matter and not at the individual level. In addition to this, they performed rituals, which were a sign of believe rs and dedication to their gods and goddesses. From the case of Roman religion, it is clear that various rituals were performed which were pivotal in the interaction between the people and the gods/goddesses. Rituals were marked by several event celebrations and public events.

Hitler :: essays research papers

Hitler came to power in Germany in the 1930s. His reign as FÃ ¼hrer of the Third Reich is known as one of the darkest periods of world history. He desired to build a supreme race. He believed the Jewish race was too large and too economically strong. To aid him in his quest for the supreme German race and to conquer Germany's economic woes, he waged a war of holocaust against the Jewish people and any "weak" human beings. This became known as "Hitler's Final Solution." America has risen to one of most powerful nations in the world. The mosaic of people that make up the "melting pot of the world" are entirely responsible for the success of this country. Diverseness unifies a nation, while prejudice and discrimination cause emotional and physical separation among the inhabitants of a country; "A nation divided cannot stand." Adolph Hitler and the Nazis, however, chose to follow their theories and ideas of creating a "supreme race" despite the contradiction with the universal principles that acknowledge the power of diversity. Jews, Gypsies, Poles, Slavs, the physically and mentally disabled, Jehovah's witnesses, homosexuals, political prisoners, dissenting clergy, and others who were considered unworthy of being a member of society, all fell Nazi victims. Over eleven million diverse, innocent people were slaughtered by the Nazis as a result of their desire to create an identical race of people. Hitler believed Marxism contrived to bestow the world to the Jews. Hitler predicted the Marxists would use democracy until they got the support of the intellectual world, then they would kill the populations. Hitler believed the most powerful nation would be one that is composed of a folkish state. Hitler's folkish philosophy promotes the supremacy of the "better and stronger" and the surrender of the "inferior and weaker." He believed that only this mightier race of people would be strong enough to withstand and overcome the problems of the future (Hitler 1: 4-l 0). Hitler wanted to rid the country of religion. He felt with all its indistinct characteristics and multiple forms, it was not only insignificant for human life, but it would lead to the disintegration of mankind. He believed that he needed to eliminate the Jewish and "harmful" concepts, opinions, and aims to be able to create this folkish state. Many Germans already had strong feelings of resentment and animosity towards the Jews. Hitler provoked these feelings by convincing them that the Jews were the cause of all evil.

How to Calculate the pH of a Weak Acid

How to Calculate the pH of a Weak Acid Calculating the pH of a weak acid is a bit more complicated than determining the pH of a strong acid because weak acids dont completely dissociate in water. Fortunately, the formula for calculating pH is simple. Heres what you do. Key Takeaways: pH of a Weak Acid Finding the pH of a weak acid is a bit more complicated than finding pH of a strong acid because the acid does not fully dissociate into its ions.The pH equation is still the same (pH -log[H]), but you need to use the acid dissociation constant (Ka) to find [H].There are two main methods of solving for hydrogen ion concentration. One involves the quadratic equation. The other assumes the weak acid barely dissociates in water and approximates the pH. Which one you choose depends on how accurate you need the answer to be. For homework, use the quadratic equation. For a quick estimate in the lab, use the approximation. pH of a Weak Acid Problem What is the pH of a 0.01 M benzoic acid solution? Given: benzoic acid Ka 6.5 x 10-5 Solution Benzoic acid dissociates in water as: C6H5COOH → H C6H5COO- The formula for Ka is: Ka [H][B-]/[HB] where:[H] concentration of H ions[B-] concentration of conjugate base ions[HB] concentration of undissociated acid moleculesfor a reaction HB → H B- Benzoic acid dissociates one H ion for every C6H5COO- ion, so [H] [C6H5COO-]. Let x represent the concentration of H that dissociates from HB, then [HB] C - x where C is the initial concentration. Enter these values into the Ka equation: Ka x  · x / (C -x)Ka x ²/(C - x)(C - x)Ka x ²x ² CKa - xKax ² Kax - CKa 0 Solve for x using the quadratic equation: x [-b  ± (b ² - 4ac) ½]/2a x [-Ka (Ka ² 4CKa) ½]/2 **Note** Technically, there are two solutions for x. Since x represents a concentration of ions in solution, the value for x cannot be negative. Enter values for Ka and C: Ka 6.5 x 10-5C 0.01 M x {-6.5 x 10-5 [(6.5 x 10-5) ² 4(0.01)(6.5 x 10-5)] ½}/2x (-6.5 x 10-5 1.6 x 10-3)/2x (1.5 x 10-3)/2x 7.7 x 10-4 Find pH: pH -log[H] pH -log(x)pH -log(7.7 x 10-4)pH -(-3.11)pH 3.11 Answer The pH of a 0.01 M benzoic acid solution is 3.11. Solution: Quick and Dirty Method to Find Weak Acid pH Most weak acids barely dissociate in solution. In this solution we found the acid only dissociated by 7.7 x 10-4 M. The original concentration was 1 x 10-2 or 770 times stronger than the dissociated ion concentration. Values for C - x then, would be very close to C to seem unchanged. If we substitute C for (C - x) in the Ka equation, Ka x ²/(C - x)Ka x ²/C With this, there is no need to use the quadratic equation to solve for x: x ² Ka ·C x ² (6.5 x 10-5)(0.01)x ² 6.5 x 10-7x 8.06 x 10-4 Find pH pH -log[H] pH -log(x)pH -log(8.06 x 10-4)pH -(-3.09)pH 3.09 Note the two answers are nearly identical with only 0.02 difference. Also notice the difference between the first methods x and the second methods x is only 0.000036 M. For most laboratory situations, the second method is good enough and much simpler. Check your work before reporting a value. The pH of a weak acid should be less than 7 (not neutral) and its usually less than the value for a strong acid. Note there are exceptions. For example, the pH of hydrochloric acid is 3.01 for a 1 mM solution, while the pH of hydrofluoric acid is also low, with a value of 3.27 for a 1 mM solution. Sources Bates, Roger G. (1973).

Transpiration Lab Report Essays

Transpiration Lab Report Essays Transpiration Lab Report Paper Transpiration Lab Report Paper When water is transported from the roots to the mesosphere cells in the leaves, it is evaporates out the stomata, called transpiration, to create a lower osmotic potential. Osmotic potential is the part of the water potential of a tissue that results from the presence of solute particles. Even though the stomata open to release water, it also brings in carbon dioxide to produce sugar and oxygen through a process of photosynthesis. The water absorbed by the roots is moved by osmosis, root pressure, adhesion, and cohesion from high to low areas of water potential. From the roots, water is transported with osmosis with a pressure pulling the water and minerals up towards the leaves. It is the transpiration pull moving it up with the help of cohesion and adhesion. Transpiration decreases the water potential causing water to move in and pull upward into the leaves and other areas of low water potential. Loss of water through transpiration can be facilitated by the opening and closing of the stomata depending on environmental condition. The rate of transpiration depends on several environmental factors such as light, humidity, temperature, ND air movement, while the rate of evaporation depends on the water potential gradient, which is contributed by gravity, pressure, and solute concentration. The purpose of this experiment is to measure pressure changes on the different types of environmental factors that affect the rate of transpiration. Hypothesis If the temperature of an environment increases, then the rate of transpiration in plants will increase and will reduce the surface area of leaves. Materials This lab requires a Labiates, Fernier Gas Pressure Sensor, utility clamps, ring tan, a leaf with its stem, plastic tubing clamps, a pipette, a refrigerator, 300 millimeter beaker, plastic syringe, water, and graphing paper. Procedures First, connect the utility clamp on the ring stand with the Gas Pressure Sensor. Then, connect the plastic syringe to one end of the 36-42 centimeter plastic tube. Place the other end of the tube in a 300 millimeter beaker of water. Then, use the syringe to draw water up into the tube until it is full. After that, connect the plastic tubing clamp on the tube. While bending the tube to make it into a U awards the sky, remove the syringe without spilling any water. Then, put the leaf with its stem in the opening of the tube with the end with the plastic tubing clamp. Carefully push the stem down of tube without spilling, and then squeeze the clamp shut. Then, connect the plastic tube to the Gas Pressure Sensor. There should be a mark on the tube at the starting water to remember for refill later on. Then, the Sensor should be connected to the Labiates. Collect data for fifteen minutes for the pressure. Then, place the leaf onto graphing paper and trace it. Find the number of surface area. After that, place the leaf in a refrigerator. Clean up the materials and return the next day. Take the leaf out of the refrigerator and set up the equipment again. Connect in the Labiates, and then find the data of the pressure for fifteen minutes. Then, place the leaf onto graphing paper and trace it. After that, calculate the surface area of the refrigerated leaf. Remember to record down other classmates variables of their different environmental conditions. Plants have adaptations to enable them to increase and decrease water lost including the shedding of leaves in colder temperatures, the peeing and closing of the stomata, thicker cuticles, and different shape of leaves depending on the environment. An advantage of closed stomata on a plant is that the plant loses water through the stomata; however to save the water it can close it. A disadvantage is that the open stomata takes in carbon dioxide for photosynthesis, but when it is closed it cannot take in carbon dioxide. The light and the fan decreased the water potential in the leaves and water moved up the stem by the transpiration pull. Conclusions During this experiment, it was found out that as temperature increases, the remonstration increased as well and as temperature decreases, the transpiration decreased as well. Therefore, this supports the hypothesis. For the class, it was found out that as sunlight increased, transpiration increased. As wind increased, transpiration increased. As humidity increased, however, transpiration decreased. These conditions led to the increased water potential gradient which causes the transpiration pull to be stronger. The control plant for all of these conditions should be the one with the most normal and stable environment. In this experiment, there were a few experimental errors such as measurement errors and incorrect us of equipment. The sensor valve was connected to the plastic tubing too early, and therefore the lab had to be restarted. There were also some technical difficulties with the Labiates because the time length was set differently than the instructions. To improve this experiment, there should two experimental temperature conditions. One was the refrigerator and the other one should be beside a heater. This will allow one to see the difference temperature changes of hot, room temperature, and cold.

Prophet Muhammad as a Religious and Political Role Model Essay - 6

Prophet Muhammad as a Religious and Political Role Model - Essay Example From the poor and needy to the rich and prosperous, the lonely and the weak, the students or teachers, the employer and employee, all of them, every person in every field of work or profession, they can all find inspiration in the life of Prophet Muhammad that entail an example for them to follow suit. Being a religious and political role model is a status that is founded on the Holy Quran as well as the Sunnah.

It is from this exploration that things such as obeying the Prophet, believing in Him, agreeing with Him and following Him come to focus. From the Holy Quran, there are verses that refer to the Prophet as a role model. One verse, however, literally refers to Muhammad as a religious and political role model, and states thus: "Verily in the messenger of Allah you have a good example for him who looks unto Allah and the Last Day, and remembers Allah much." The original verse had the Arabic word use, which translates to model or example that should be followed and obeyed. Someone who follows another person is bound to imitate them, follow their style as well as attitudes, in the end identifying themselves with that person.

This verse is a revelation of the significance of the Prophet’s Sunnah in the Muslim’s lives. It is also worth noting that according to the Holy Quran, Prophet Muhammad has a superior character and is one who exemplifies a perfect lifestyle worthy of emulating.
