Isotopes And Atomic Mass Essays - Chemistry, Nature,

Isotopes and Atomic Mass Objective: 1. Determine the average weight of each isotope of the fictitious element vegium. 2. Determine the relative abundance of isotopes of vegium. 3. Calculate from experimental data the atomic mass of vegium. Materials: A sample of vegium on a plastic cupsmall-scale balance Procedures: 1. Weigh all the beans, all the peas, and all the corn. 2. count all the beans, all the peas, and all the corn. 3. Divide all the mass of each by the isotope (beans, peas, and corn) by the number of each isotope to get the average mass of each isotope. 4. Divide the number of each isotope by the total number of particles, and multiply by 100 to get the percent abundance of each isotope. 5. Divide the percent abundance from step 4 by 100 to get the relative abundance of each isotope. 6. Multiply the relative abundance from step 5 by the average mass of each isotope to get the relative weight of each isotope. 7. Add the relative weights to get the average mass of all particles in vegium, the "atomic mass." Note: When you weigh the various types of vegetables, you may encounter some problems. For example, the sample of beans might be too large to weigh on your balance. You might solve this problem by making more weights or by using a larger counterweight on your balance. This approach increases your balance's capacity. Keep in mind that it also results in a heavier beam, which reduces the sensitivity of your balance. Alternatively, you might weigh a portion of your vegetables, say half, and then multiply your result by two (or a fifth and multiply by five). The beans are various in sizes, so if you weigh just one bean, and multiply by the number of beans to get the total weight of beans, a significant error might result. Weigh a large enough sample so you get a good estimation of the average weight of a bean.

To get the Relative abundance, we divided by 100. About the same as moving the decimal to the left 2 places. To ensure that the answers were right, the percent of each is supposed to be as close to 100% as possible. We came very close. Conclusion: In determining we found all the averages of the weights of each isotope. In calculating the experimental data the atomic mass of vegium, we answered that question successfully. And in the second determining, we determined the relative abundance of isotopes successfully. SOE: 1. While counting the beans, there were more than 450 total pieces, so while counting we could have miscounted because the half-peas looked a lot like corn. 2. While weighing, we had to tare the beaker, This can sometimes prove to be inaccurate. 3. The percent of each row, the total is 99.999%, to be 100% accurate, the number has to be 100%. This proves that somewhere down the line, we didn't calculate right. The probable cause for this is that we didn't list all numbers. The real numbers were over 10 characters long, we used SigFigs.

Conjugating Croître in French

Conjugating Croà ®tre in French In French, there are a few options for saying to grow. One of those is  croà ®tre  and is the subject of this verb conjugation lesson.

HTML and e-commerce Essay Example | Topics and Well Written Essays - 2500 words

HTML and e-commerce - Essay Example HTML has become the language of all webs. All web pages are written in HTML. It is a markup language and surrounded by many other markup languages like SGML, XML and many more. Html by having more precise and efficient functions effectively distinguishes the other markup languages. Another reason of HTML distinction is that it not only included the features that was found in prior markup languages but accumulated by many more like it has more complicated style and content tags integrated into one language. It has a tag that separately defines the content with tag like H1, in order to define style it uses a FONT tag (Schaum's, 2003). It is of necessity that now web documents are defined by the HTML because of its excessively constructive features. However, HTML is an essential markup language used for web pages. It involves many features from which building blocks of all websites are formed. It is used to slot-in varied images and objects on the web and allow interactivity between user and computer. HTML is used to embed video without any authority, and is very handy for web developers who exhibits graphics easily and pleasantly. Many individuals facilitate the relocation of computer files to their mobile by the use of HTML5. Web pages have been expanding its utility by getting large storage of information. We browsers also attribute Cascading Style Sheets (CSS) which labels the emergence and outline of the text and the matter contained (Powell, 1998 ). Question 2 Examine the purpose of client servers and browsers and the function of the search engine for technology software house. To examine the function of clie nt server and browser we can use the mechanism that occurred between these two regions. Client server is basically a server used to form the communication for a wide range. Clients are browsers that always initiate in this mechanism to forward the details to the server which it is asked for. The server application waits inertly to have the instructions from clients and then accordingly provides the specific services into browser by which user can further proceed. The browser allows the users to look through the resources accessible on the server. Users can browse any resource that could be present in the server or for the documents with dynamism depending on the user’s requirements (Kiley Mitchell). We can say that the browser function is to advance the user’s detail to server for demonstration. The main purpose of search engines is associated with finding targeted keyword information, sorting it properly, storing in an organized manner and finally ranking the valuable information found on the web. On the other way, server responses to the instruction put into the browser by the user. All communications between browsers and servers use the Hypertext Transfer Protocol (HTTP). The pattern in which clients and servers exchange messages is referring to the request-response messaging mold. The reason of the effective communication between clients and server is certainly highlighting the common language between them (Thurow, 2003 ). Web crawlers and indexing are few of the notable functionalities associated with search engines. Crawlers are designed in a manner that it can locate any new information available on the internet within seconds and then ranks it

Jeffrey Garten speech Essay Example | Topics and Well Written Essays - 500 words

Jeffrey Garten speech - Essay Example Unemployment in the US was last reported at 9.60% as of September 2010, a record high, as compared to 5.40% unemployment rate since 1948 to 2010, with exception of 1953 that has a low 2.53% (Trading Economics, 2010). Perhaps, the reduction of employment is the meaning of cultural change to Professor Garten because lifestyle and spending behavior of people greatly changes with unemployment problem. A host of problems appeared because of the recent financial crisis such that the US took trade liberalization and deregulation to bail its sinking economy. Professor Garten acknowledged the presence of the emerging countries that share in the wealth distribution of the world economy. In his speech, he identified China, India and Brazil as the countries that are now restructuring their economies in the market line of technology transfers, trade opportunities and foreign direct investments. These countries have their own model of capitalism because of their own powerhouse, large base of resources, big population and large markets. As these countries offered trade liberalization, business opportunities are now open for employers to enter into trade relations in this country. Because of this, investors have other options for trade opportunities other than U.S. For example, India has been the preferred outsource call centers in many parts of the globe (Call Centers in India, n.d.) In this respect, companies and individuals must be ready to adapt to this changing economy. In order to take advantage of the emerging economy, companies must also think globally and be equipped with proper strategies needed. By doing so, its own employees will also absorb the economic changes that is brought about by technology transfers. Following the trend of Professor Gartner’s speech, he is correct in saying that there will come a time that these emerging countries will have their own rule to play because of the importance of their role in the economy, and

Informational Privacy Essay Example for Free

Informational Privacy Essay The divide between the law and human ethics has been a rather blurred one, with many people wondering where the dividing line ought to be drawn (Rowland, 2005). For on the one hand the law ought to be obeyed and not questioned as it is the supreme authority of the country; yet on the other hand ethical considerations, especially in cases where the law is silent, ought to be considered too. For many are the times when the law has failed to be of any use because it is either obsolete due to age or it just does not take into account changes in life. Technological advancement is one area where the law has totally failed to keep up pace with new issues that emerge with the result that it has been difficult, even impossible, to have sound decisions on matters of technology (Rowland, 2005). This paper considers a case of information privacy from the point of view of the parents of a naval officer whose emails they cannot access after his death. Discussion Justin Ellsworths Parents ought to have been allowed access to their son’s emails because of a number of reasons. The first one is that according to the utilitarian theory, this is a man who had done so much for his nation (Rowland, 2005). He had given his own life in exchange for the lives of many other Americans whom he sought to protect from their enemies. He literally died serving his nation. In this case he was of great use and value to the nation. On this basis, the parents, who are his next of kin, ought to have been allowed to access his emails. One thing is critical in this entire case – the parents do not merely want access their son’s email but want to do this for a good reason. The reason is that he died away in battle unexpectedly and so left no final word to them. They are obligated to know what their son might have though or said prior to his death so they might understand his possible feelings then. Secondly, as people who are bereft of their son, these parents can probably be little comforted in sharing in the feelings of their son – feelings they can only get if they are able to access his email. Finally, it is worth considering the alternative – if they are not allowed access, they will probably be less happy, develop negative attitudes towards the authorities and the law enforcement agencies, and most likely even develop a hatred for any form of government service. They might even engage in dissuading other people from ever considering to be patriotic based on their own experience that patriotism is never rewarded. The eventuality could be that fewer people would be wiling to enlist as servicemen and women in the country’s naval forces. The reason is that their son as not treated with the worth he deserved. Finally, the emails will be of no use to anyone else after all so keeping them or deleting when someone desperately them is essentially despising the person. Deontological ethical considerations require that everything be done in accordance with the law (Rowland, 2005). On this basis, it is all right for Justin Ellsworths Parents to be denied access to the emails belonging to their son. And privacy law is one that ought not to be broken at all because breaking it is both an offence as unethical. Imagine accessing the secret thoughts of a mature person. This is a person who, unlike a child, could express himself. If he had any information intended for parents he must have send it over. Above all, else, he entered into agreement with Yahoo not to disclose his personal information. This contract is binding for as long as his account is not terminated. Such information may never be shared or disclosed to third parties regardless of their closeness to him. It is about obligation, duty, and responsibility. Not every law is popular with all people; but the law is designed to serve mankind and not mankind to serve the law (Rowland, 2005). This in essence means that the law or a duty or an obligation that one party has towards another cannot be changed just like that. Agreements are binding legally and can only be nullified or revoked by mutual agreement between the parties to the agreement. So, as long as the law requires that there is no access, there ought to be no access. It is a universal law and is also fair – granting justice to the offender and the offended as well. In fact acting in the right way morally is only possible when the actors are made to have a sense of duty and responsibility. Without such a sense, they will tend to be less concerned (Rowland, 2005). Conclusion The difference between utilitarian and deontological approaches to life issues is that while the former justifies an act based on its inherent worth or utility, the latter purely bases the worth of an issue on its ability to adhere to ethical or moral issues which in turn are brought about by having a sense of duty. This means that the argument as to whether or not Justin Ellsworths Parents ought to have been allowed to gain access to their son’s emails is dependent on which side of the two theories one is considering. If it is the deontological one, then they ought not to be allowed it is against the law; but if it is utilitarianism then they deserve to be allowed for Justin Ellsworth was of great value to the country.

John Donne :: essays research papers

Essay on John Donne John Donne, a master at his work, was born some time during the year 1572. The exact date of his birth date is unknown. Donne accomplished many and experienced many things in his life. He got married secretly, went to prison, and wrote many poems that are world known John Donne attended both Oxford and Cambridge universities, and he also attended Lincoln's Inn. At Lincoln's Inn Donne studied law, but never practiced it there after. Donne did not get degrees at any of the universities that he attended, but he did obtain a mind full of knowledge. As Donne grew up as a child, his parents raised him up in a Catholic household. During the 1590's, Donne abandoned Catholicism and looked toward to become an Anglican. In Donne's later years he wrote two Anti-Catholic poems (Pseudo-Martyr and Ignatius his Conclave). Donne later became a preacher. He had a metaphorical style which made him a great preacher. Donne received a degree of divinity from the University of Cambridge and was made a royal chaplain. In 1601 John Donne secretly married a woman by the name of Ann More. This act ruined his employment at that time. Donne was appointed private secretary to Sir Thomas Egerton in 1958. Ann More was, ironically, the niece of Lady Egerton.The secret marriage diminished Donne's hope for his advancement with Sir Thomas Egerton. John Donne was even imprisoned by Sir George More for marrying Ann More. One of the most traumatic experiences that Donne faced was the death of his wife. Ann died while giving birth to a still born in August of 1617. John loved his wife very much and mourned the death of her loss. They were married to each other for fifteen and a half years. Donne pays tribute to her on her grave stone by inscribing words such as "a most excellent and beloved woman, a most loving and chaste wife, a most dutiful and forbearing mother".

Religion and Identity Essay

The question often arrived what is religion? There are more than one answer to this depending on one’s culture, identity, ethics and beliefs. Religion can be found in different cultures and throughout the whole period of human history. There is evidence that shows signs of religion such as animal spirits in art and human burials that suggest the belief in life after death. There have been many different answers and definition to what religion is (Van Voorst, 2013). According to Robert E. Van Voorst (2013), religion is â€Å"Pattern of beliefs and practices that expresses and enacts what a community regards as sacred and/or ultimate about life (pg.5). In addition to that, there is the separation of church and state. In America, the right to freedom of religion is very central to the American democracy that it was preserved in the First Amendment to the Constitution along with other rights such as freedom of speech and freedom of press. The country’s founders restrict the separation of church and state. This is due to the prohibition against government regulation or endorsement of religion. According to American Civil Liberties Union of Florida (2012), the standard of separation has been regularly tested. In early America, even after church establishment ended, some state legislators sought to revive the compulsory taxation of citizens to support religious institutions. In this century, public schools were once required to teach the biblical version of the earth’s and humanity’s creation, while the scientific theory of evolution was prohibited. Throughout our history, sectarian advocates have tried to inject religious exercises, such as daily prayer, into the public schools. At times, religious minorities, including members of â€Å"cults,† have been discriminated against because of their beliefs. And today, many citizens in many communities disagree about whether a model of the infant Jesus in the manger, which officially promotes certain religious beliefs over others, should be displayed on the steps of City Hall. The courts must frequently consider where to draw the line that separates church and state ( ¶5). Religion is one of our most critical tradition and constitutional rights and must stand against anything that would challenge the standard of separation, which protects that freedom. Reid Temple African Methodist Episcopal Church was the group that I visited. Though it is not my own religious practice, it qualifies as a religion. Driving up to the church there is a sign that has the name of the church boldly written in LED lights. The welcome message display in red across the board says â€Å"All Are Welcome†. Inside of Reid Temple church they have a Cross as their symbol posted high where all can see. The service was nice with the choir singing praises to God and special prayer request were taken. After the service, I spoke with the Senior Pastor about his church and what exactly do they believe in. I was informed that their slogan is â€Å"Aiming to Please through the 5 E’s. This came from II Corinthians 5:9 which states â€Å"So whether at home or away, we make our aim to please Him. (RSV). The 5 E’s were described to me as â€Å"Evangelism which is sowing the seed of God’s Word in the hearts of all people. Empowerment which is bestowing love and guidance on believers to disciple them in fulfilling their purpose. Education which is knowing the will of God through study and obedience of His Word. Economics which is flowing in financial prosperity according to God’s wealth principles and Expansion which is growing in all ministry areas to reach the growing harvest of souls† ( Washington, L. Personal interview January 13, 2013). The cross is a reminder of their pledge and it also reminds them that Jesus died for their sins and to Him all praise is given. Buddhism also has a symbol such as the Dharmachakra which is the wheel of the law. The eight spokes on the wheel represents the eightfold path. The wheel is one of the most important Buddhist symbols because it symbolizes the teachings of Buddha. According to Thames & Hudson (2004), The wheel’s motion is a metaphor for the rapid spiritual change engendered by the teachings of the Buddha: the Buddha’s first discourse at the Deer Park in Sarnath is known as the â€Å"first turning of the wheel of dharma.† His subsequent discourses at Rajgir and Shravasti are known as the â€Å"second and third turnings of the wheel of dharma.† The eight spokes of the wheel symbolize the Noble Eightfold Path set out by the Buddha in his teachings. The wheel also represents the endless cycle of samsara, or rebirth, which can only be escaped by means of the Buddha’s teachings. And some Buddhists regard the the wheel’s three basic parts as symbols of the â€Å"three trainings† in Buddhist practice: The hub symbolizes moral discipline, which stabilizes the mind. The spokes (usually there are eight) represent wisdom which is applied to defeat ignorance. The rim represents training in concentration, which holds everything else together ( ¶ 2 & 3). In the early days, the Dharmachakra not only symbolizes the teaching of Buddha but also Buddha himself. Today, it appears in the art of every Buddhist culture (para 5). Practicing religion can shape an individual and group identity. Take Buddhism for example that is followed by many Indians. This religion practices the Four Noble Truths and the Eightfold Path. The Four Noble Truths teaches that: 1. All life is suffering- this suggests that all beings experience suffering and that it can be ranged from great physical and mental pain to mild emotional unhappiness. Suffering originates from anger and sadness but then happiness is also suffering because it comes and goes. 2. The cause of suffering is desire- This suggests that humans want what they do not have and should not have. Humans’ personal desire for happiness is the cause of the suffering. 3. To end desire is to end suffering -which suggests that putting all craving and personal desires to an end will therefore end the suffering. This breaks the negative karma which leads to the 4th Noble Truth 4. To end desire- one must follow the Noble Eightfold Path. The Eightfold Path is : 1. The right to understanding which ends the concept of what one think is reality and see reality as it is. 2. The right to intention is where people must want to change before they can actually be change. 3. The right to speech which is speaking the truth at all times. 4. The right to conduct which means no killing, stealing, drinking, intoxicants and being sexual. 5. The right to livelihood which is working and living a life that does not cause others harm. 6. The right to effort which is developing a conscious free from craving. 7. The right to mindfulness which is to be aware and mindful and 8. The right to contemplation which is the deepening of mindfulness that leads to concentration and insight may be obtained (Van Voorst,2013). Practicing the Four Noble Truths and The Eightfold Path teaches and shape the followers of Buddhism. It is a way of life for them which teach them to take time to find out who they are and what they are all about. It is a guideline to ethical and menta l development. Shinto culture is another example of how practicing religion and shape individuals or groups. The people of Japan practices Shinto and is rooted in the people there and their traditions. The Shinto gods that are called kami are sacred spirits. These spirits can take form in things such as wind, rain, mountains, trees, rivers and fertility. Shinto religion believes that when a human dies they become a kami and is given back to their families and ancestral kami. There not a right from wrong in Shinto and their faith is based on being optimistic. The Shinto faith is blended with other beliefs such as that of Buddhism and Daoism. It does not have a founder, written documents, formalized ethics, system of beliefs, scripture or an organized system of theology but with the blend of Buddhism and Daoism, the Japanese culture now have a system of beliefs, written documents, founder, ethics and all that it was lacked before. It is still a central religion of Japan (Carroll, 2012). Shinto grounds are very sacred and behavior must be proper at all times. There are no food or drink allowed and there must be silence or hushed voices. Purity is important in Shinto and there is a certain procedure in washing your hands on mouth. Purity is important in pleasing the kami which brings a happy life. Van Voorst wrote that â€Å"Cleanliness in particular signifies a good character and freedom from bad external influences. In Western societies one hears the proverb â€Å"Cleanliness is next to godliness.† In traditional Japanese society cleanliness—of body, mind, and spirit, both ritual and practical—is godliness. To be in harmony with the kami, one must keep one’s person, home, and business clean† (pg 198). Religion has always been connected with government and politics. The Western world has a history of influence from Catholicism and Protestant rift. It is very similar to the history of some parts of Southern Asia that have been influenced by Islam. The interconnection of both religion and government is to be expected because both are regulating social behavior. During the past century, religion has been less influential. Modern governments have been influenced by Democratic philosophy which put importance of the average man and a sharing of the world’s resources. These ideas continue to shape modern society in different ways. For example, technology has drastically changed the nature of life and work. Traditional religious systems are gradually becoming less important. The trend towards secularism continues but has not been nearly as pronounced in the United States and regular church attendance started to decrease in the 1960’s and early 1970’s. It increased again post World War II period. There is only a small majority of Americans who thinks religion is of any importance in their lives (Federal Funding of Faith-Based Services, 2011). Many people know what religion is until they are asked to define it. Religion is a worldly thing, across many boundaries in human experience and so that makes it a bit hard to define. There are a few different definition of religion and many have different religious experience and understanding of Ultimate Reality. At Reid Temple, I asked the lady sitting next to me if she could tell what Ultimate Reality means. She said to her Ultimate Reality meant a personal relationship with God. In a different culture Ultimate Reality could mean spiritual growth or spiritual path. Not everyone is all about religion though. There are some cultures who prefer that their beliefs not to be subject as a religion but as a faith or teaching. There are some who argue that they are not religious but they are spiritual.
