Alpha Decay Nuclear Reaction Example Problem

Alpha Decay Nuclear Reaction Example Problem This example problem demonstrates how to write a nuclear reaction process involving alpha decay. Problem: An atom of 241Am95 undergoes alpha decay and produces an alpha particle.Write a chemical equation showing this reaction. Solution: Nuclear reactions need to have the sum of protons and neutrons the same on both sides of the equation. The number of protons must also be consistent on both sides of the reaction.Alpha decay occurs when the nucleus of an atom spontaneously ejects an alpha particle. The alpha particle is the same as a helium nucleus with 2 protons and 2 neutrons. This means the number of protons in the nucleus is reduced by 2 and the total number of nucleons is reduced by 4.241Am95 → ZXA 4He2A number of protons 95 - 2 93X the element with atomic number 93According to the periodic table, X neptunium or Np.The mass number is reduced by 4.Z 241 - 4 237Substitute these values into the reaction:241Am95 → 237Np93 4He2

The Best Quotes From 19th Century Feminist Lucy Stone

The Best Quotes From 19th Century Feminist Lucy Stone Lucy Stone (1818-1893) was a 19th-century feminist and abolitionist who is known for keeping her own name after marriage. She married into the Blackwell family; her husbands sisters included pioneer physicians  Elizabeth Blackwell  and Emily Blackwell. Another Blackwell brother was married to Lucy Stones close confidant, pioneer woman minister  Antoinette Brown Blackwell. On Equal Rights The idea of equal rights was in the air. I think, with never-ending gratitude, that the young women of today do not and can never know at what price their right to free speech and to speak at all in public has been earned. (From her speech, The Progress of Fifty Years) We, the people of the United States. Which We, the people? The women were not included. We want rights. The flour-merchant, the house-builder, and the postman charge us no less on account of our sex; but when we endeavor to earn money to pay all these, then, indeed, we find the difference. I expect to plead not for the slave only, but for suffering humanity everywhere. Especially do I mean to labor for the elevation of my sex. I was a woman before I was an abolitionist. I must speak for the women. We believe that personal independence and equal human rights can never be forfeited, except for crime; that marriage should be an equal and permanent partnership, and so recognized by law; that until it is so recognized, married partners should provide against the radical injustice of present laws, by every means in their power... On the Right to Education Whatever the reason, the idea was born that women could and should be educated. It lifted a mountain load from woman. It shattered the idea, everywhere pervasive as the atmosphere, that women were incapable of education, and would be less womanly, less desirable in every way, if they had it. However much it may have been resented, women accepted the idea of their intellectual inequality. I asked my brother: Can girls learn Greek? The right to education and to free speech having been gained for woman, in the long run every other good thing was sure to be obtained. Henceforth the leaves of the tree of knowledge were for women, and for the healing of the nations. On the Right to Vote You may talk about Free Love, if you please, but we are to have the right to vote. Today we are fined, imprisoned, and hanged, without a jury trial by our peers. You shall not cheat us by getting us off to talk about something else. When we get the suffrage, then you may taunt us with anything you please, and we will then talk about it as long as you please. On Occupations and a Womans Sphere If a woman earned a dollar by scrubbing, her husband had a right to take the dollar and go and get drunk with it and beat her afterwards. It was his dollar. Women are in bondage; their clothes are a great hindrance to their engaging in any business which will make them pecuniarily independent, and since the soul of womanhood never can be queenly and noble so long as it must beg bread for its body, is it not better, even at the expense of a vast deal of annoyance, that they whose lives deserve respect and are greater than their garments should give an example by which woman may more easily work out her own emancipation? Too much has already been said and written about womens sphere. Leave women, then, to find their sphere. Half a century ago women were at an infinite disadvantage in regard to their occupations. The idea that their sphere was at home, and only at home, was like a band of steel on society. But the spinning-wheel and the loom, which had given employment to women, had been superseded by machinery, and something else had to take their places. The taking care of the house and children, and the family sewing, and teaching the little summer school at a dollar per week, could not supply the needs nor fill the aspirations of women. But every departure from these conceded things was met with the cry, You want to get out of your sphere, or, To take women out of their sphere; and that was to fly in the face of Providence, to unsex yourself in short, to be monstrous women, women who, while they orated in public, wanted men to rock the cradle and wash the dishes. We pleaded that whatever was fit to be done at all might with propriety be done by anybody who did it well; that the tools belonged to thos e who could use them; that the possession of a power presupposed a right to its use. I know, Mother, you feel badly and that you would prefer to have me take some other course, if I could in conscience. Yet, Mother, I know you too well to suppose that you would wish me to turn away from what I think is my duty. I surely would not be a public speaker if I sought a life of ease, for it will be a most laborious one; nor would I do it for the sake of honor, for I know that I shall be disesteemed, even hated, by some who are now my friends, or who profess to be. Neither would I do it if I sought wealth, because I could secure it with far more ease and worldly honor by being a teacher. If I would be true to myself, true to my Heavenly Father, I must pursue that course of conduct which, to me, appears best calculated to promote the highest good of the world. The first woman minister, Antoinette Brown, had to meet ridicule and opposition that can hardly be conceived to-day. Now there are women ministers, east and west, all over the country. ... for these years I can only be a mother- no trivial thing, either. But I do believe that a womans truest place is in a home, with a husband and with children, and with large freedom, pecuniary freedom, personal freedom, and the right to vote.  (Lucy Stone to her adult daughter, Alice Stone Blackwell) I know not what you believe of God, but I believe He gave yearnings and longings to be filled, and that He did not mean all our time should be devoted to feeding and clothing the body. On Slavery If, while I hear the shriek of the slave mother robbed of her little ones, I do not open my mouth for the dumb, am I not guilty? Or should I go from house to house to do it, when I could tell so many more in less time, if they should be gathered in one place? You would not object or think it wrong, for a man to plead the cause of the suffering and the outcast; and surely the moral character of the act is not changed because it is done by a woman. The anti-slavery cause had come to break stronger fetters than those that held the slave. The idea of equal rights was in the air. The wail of the slave, his clanking fetters, his utter need, appealed to everybody. Women heard. Angelina and Sara Grimki and Abby Kelly went out to speak for the slaves. Such a thing had never been heard of. An earthquake shock could hardly have startled the community more. Some of the abolitionists forgot the slave in their efforts to silence the women. The Anti-Slavery Society rent itself in twain over the subject. The Church was moved to its very foundation in opposition. On Identity and Courage A wife should no more take her husbands name than he should hers. My name is my identity and must not be lost. I believe that the influence of woman will save the country before every other power. Now all we need is to continue to speak the truth fearlessly, and we shall add to our number those who will turn the scale to the side of equal and full justice in all things. In education, in marriage, in religion, in everything disappointment is the lot of women. It shall be the business of my life to deepen that disappointment in every womans heart until she bows down to it no longer. Make the world better.

Different situations in the school Essay Example for Free

Different situations in the school Essay It is found out that parents of children suffering from learning disabilities represent other parents in expression regarding children’s upbringing, education as well as disabilities. Â  Understanding of these parents’ concerns greatly contributes to children’s education since they work together with teachers to assist the disabled children. It is not appropriate to generalize situations of parents whose children suffer from learning disabilities. This is because; the parents have different approaches of dealing with their children’s situation which is necessitated by their different backgrounds. (Myklebust, 2008) Parents have very high expectations, dreams as well as hope concerning their children’s life long before those children is born. The primary hope for every parent is to have healthy children regardless of the kind of sex and the preference of a desired sex comes after good health aspect. In cases where a child is found to possess disabilities and in this particular case, learning disabilities, parents lose dreams that they previously had for their children and they try to replace them with new dreams that fit children’s type of disability. However, grief associated with learning disability possessed by children tend to recur in parents’ mind periodically including previous expectations that fail to take place which mainly occurs during anniversaries. (Donahue, 2002) Parents’ Experiences, Understanding and Expectations for Their Children with Learning Disabilities The parents of millennial generation children are noticed to have more concern for aspects related to their children’s education particularly for those suffering from learning disabilities. Among the areas of concern for this category of parents is safety where parents are concerned with whether their children’s feelings as well as emotions are safe. This is because they fear a situation where they may get hurt by being looked down upon by other normal children. They also worry of the manner in which school personnel treat their children when they fail to respond to learning as expected. Since learning disabilities attract special attention to this category of children, they tend to be vulnerable to bully from other normal children which also affects children’s emotions negatively. (Ramcharan, 2005) The situation where parents mind about their children’s safety sometimes leads to overprotection on the side of children suffering from learning disabilities. This develops negative effects on those children’s development and some of these children suffering find this kind of treatment inappropriate as compared to their age. (Sigel, 2006) Another area of concern for parents whose children possess learning disabilities regards other children’s as well as parents’ attitudes towards their children’s situation of learning disability. They wonder whether their children will be accepted or will be alienated due to their possession of learning disabilities. For instance, some parents of non-disabled children consider education funds directed to education of children who possess learning disabilities as going to waste. They prefer that the funds are entirely used on their children who are more productive. Parents of children possessing learning disabilities experience difficulties in explaining the disability situation to their children. This affects the relationship between them since the children feel that some truth regarding their disability is being hidden from them, which is the reason as to why they are accorded much attention. (Goss, 2001) Attitudes and Experiences of Children Possessing Learning Disabilities within Different Learning Environments There is a wide variety of experiences as well as attitudes that children suffering from learning disabilities undergo within learning environments. These experiences include a situation where they are discriminated by fellow students and find it difficult to have friends as normal students do. This is contributed by their inability to keep up with their friends’ knowledge and speed to learn and understand things which makes them to be alienated. The fact that these children are mostly with their teachers receiving extra guidance on topics taught in class when others are playing make it difficult for other children to interact with them due to the ever presence of their teacher. It follows that children suffering from learning disabilities are always around their teachers where they tend to develop comfort which denies them a chance to learn how to associate with peers. This category of children also finds that avenues in which they can make friends are limited in their learning environment. In cases where there are extracurricular activities in which they can indulge in, they lack time for that since they are mostly getting special classes during their free time. (Gates, 2003) There are situations where children’s learning disabilities tend to overshadow their abilities according to their teachers’ perception. Some teachers direct their focus on the children’s situation rather than capability of those children to develop some understanding of educational concepts. For instance, a teacher may recognize a child’s struggles with science subjects to a point that he/she fails to recognize that the child is gifted in art. This negatively affects this category of children as they feel very inadequate since they are not appreciated for what they are good at doing. (Butler, 2002) Some school personnel may be willing to appreciate areas that children are good at, but it is hindered by identification methods applied in learning environments. Identification is normally conducted through standardized tests which is not the appropriate measure for their giftedness. The standardized tests require some adjustment as well as modifications before being imposed on the children in order to point areas in which they are gifted. (Taylor, 2005) The achievements of children possessing learning disabilities sometimes go unrecognized since there is no clear separation between the work done by teachers and that done by the children. Some people feel that their achievements are accompanied by so much follow up from teachers. This demoralizes the children especially when they are sure that they contributed quite a lot towards their success. Another disturbing situation for children suffering from learning disability is where they have to shift from schooling levels like when moving from elementary level to secondary level. Another transition is when this category of children’s families relocates to new residential areas where the children have to change schools. Children suffering from learning disabilities find it hard to adjust during these two transition periods. The main difficulty comes where they have to initiate new relationships in their new schooling levels as well as schools. That is; they have to introduce themselves and their situation to their new teachers who might treat them differently from their previous school personnel. This makes children to feel out of place when they realize that they are taking more time to adjust compared to normal children and even more when the new learning environment fails to fit their needs appropriately. (Westwood, 2003) These children feel stressed and pessimistic about starting the process of getting special attention in learning with the new school personnel. This stress and discomfort realized from difficulties encountered in adjusting to unfamiliar learning situation is normally manifested in some weird behaviour that was not previously recognized in the children which shows that the transition situation affects them psychologically. (Adelman, 2007) There are certain characteristics that describe the learning environment that children suffering from learning disabilities consider ideal, in which they would be absolutely comfortable if the were provided to them. These include a learning environment where needs, concerns as well as dreams of these children are accorded consideration by their teachers. They also prefer that their disability does not hinder their teachers from recognizing areas where they are gifted. Concerning the manner in which other children treat them, these children would prefer that other children interact with them freely without discriminating them due to their situation. (Kravets, 2003) Conclusion It is clear that; parents encounter distinct experiences with children suffering from learning disabilities including the situation where parents are not in a position to explain the learning disability situation to their children. This affects the relationship between parents and their children since the children feel that everything is not being revealed concerning their situation. These children also encounter challenging experiences from their learning environments. This is normally because they are not treated as they would prefer which makes them feel out of place. They point out that they would prefer to be integrated with other normal children in order that their learning disabilities do not hinder them from living a happy life. They also prefer that everything about their learning disability is disclosed to them in order that they get to know their level of disability and work towards adjusting it. (Sattler, 2007)

Affirmative Action Must Play a Role in College Admissions Essay

Anxiously awaiting its contents, the high school senior stares at his mailbox. He has been awaiting a response for months from his dream college. He has endured the endless questions from friends and family, "Did you hear from that college yet?" He has spent many a night he should have been sleeping lying in bed wondering whether he would be heading to his dream school in the fall. He has read numerous books and has done serious research on just what it took to get where he wanted to be. He continues to stare for hours, shaking from either anticipation or fear, though he cannot decide which. Finally his parents arrive home and encourage him to open the letter. He then opens the box. Now I ask this. Should this senior’s ethnicity impact whether his envelope is thin or thick? Should he have a better chance to attend his dream school because he is a minority? Or do the questions go deeper than the single factor of ethnicity? The issue of Affirmative Action, preferences towards persons of racial minorities to compensate for prior discrimination, in college admissions is a quite complicated one. Many sides must be explored to gain a better understanding of the theories and views on this issue. It is not easily answered with a yes or no. Since its inception, Affirmative Action’s use has been a major debate in American society. Many questions are left to be investigated. Many believe that we should live in a society where preferential treatment could be eliminated, and admission to college is based solely on one’s merit and character, yet this view seems quite unrealistic. The United States Supreme Court handed down its first decision on this complex issue with the case of Allan Bakke. Allan Bakke was a white male who applied to ... ...ns. The evidence supports the fact that if racial preferences are not used in admissions, the country will be withholding quality educations, both graduate and undergraduate, from large numbers of minority students. One of the staples of slavery when it is employed in this world is preventing those who are enslaved from becoming educated. We must work for the advancement of the human race as a whole, and this includes making sure that entire races of people are not left off prematurely on the road of education.

The Odyssey and Propaganda

â€Å"Homer’s The Odyssey and Virgil’s Aeneid as Propagandistic Literature† Propaganda is a powerful social tool that influences audiences through manipulation and selective viewpoints and has been witnessed in history as far back as written records exist. It has been used to sanction the rise of new leaders, herald a society and its dominance, and push ideological agendas to audiences of all backgrounds throughout civilizations. The methods that propaganda has been used are numerous and include both written and spoken forms of communication to reach the audience.Literature is not exempt from the use of propaganda and Homer’s The Odyssey and Virgil’s The Aeneid are two historical sources where it can be found. The propaganda seen in these texts share similarities and differences which can be compared and contrasted and include the values of the societies they represent, the destinies of the heroes and what each represents to the society, and how the backgrounds of the creators influence what occurs in the story with emphasis on politics and traditions.The Odyssey shares similar propaganda to The Aeneid, although it is not as immediately apparent given the historical backgrounds that led to the creation of each, in regards to the political and social changes being experienced around the time The Aeneid was written. The type of propaganda that is emphasized in The Odyssey is based around the dominance and traditions of Ancient Greek society and culture, the necessity of honoring the gods and goddesses, and maintaining virtues that are universal throughout society while emphasizing the importance of the individual.It is demonstrated through the journey of Odysseus, which begins with the Trojan War and follows with each adventure that he experiences on his return to Ithaca, ending on a message of the importance of homecoming when he reaches the shores of his island. The dominance of Ancient Greek society is displayed immediately i n the backstory of how the Achaeans overcame the city of Troy and won the Trojan War. It emphasizes the intelligence and cunning of the Achaeans through the example of the Trojan Horse which Odysseus thought of that was used to infiltrate the city. That the Greeks would emerge victorious at the end of a en-year siege over a powerful foe demonstrates the strength of the society militarily. Cultural influences that are affected by propaganda in The Odyssey demonstrate the achievements, values, and traditions of Ancient Greece through references to the ideal individual, proper hospitality, and the honoring of the gods and goddesses. The individual in Ancient Greek society was valued as a strong mental and physical person, who displayed cunning and strength, had a silver tongue and demonstrated articulate thoughts through powerful rhetoric, that could handle any challenge while creating an eternal legacy.The ideal individual was also loyal to his family and society, and was dedicated to the values and traditions instilled in them from birth. This is all demonstrated through Odysseus and his actions, from creating the idea of the Trojan Horse and displaying leadership in battle, to outsmarting the cyclops Polyphemus, to having an unfaltering love for his wife Penelope. Proper hospitality is explained through the suitors that have overrun Odysseus’s home, who slaughter his animals, drink his wine, and made themselves unwelcome guests. Homer is able to provide an example of how not to act when a person is a guest in another’s home.Conversely, he demonstrates proper hospitality by using the goatherd as an example when he takes a disguised beggar that is Odysseus into his home. The honoring of the gods and goddesses that were above all mortal men and women was important in the culture of Greek society, and this is demonstrated through the events of The Odyssey, whether it is praying to a god for safety and wellbeing, acting in a way so as not to anger a g od such as Poseidon, offering sacrifice to honor the legacy of a god or drinking to the honor of a god to gain their support.Homecoming is the destiny that is attributed to the story of Odysseus and his fate of returning to Ithaca emphasizes the importance of never leaving the place you were born or the ones you love, a value that was important to Ancient Greek society. These are all examples of propaganda that was used in The Odyssey, which was shared through a rich oral tradition that helped instill these ideals and virtues into the core of Ancient Greek society. Unlike The Odyssey, which began as an oral story and then written at a later date, The Aeneid was written from the point of its creation.It originated at a time of political and social change in Roman society, which influenced not only its creation but the characters and story in it. According to the â€Å"Vita Servii [which] states that the writing of the Aeneid had been undertaken at the express proposal of the emperor † (Avery 225). As it was commissioned by Augustus Caesar, this meant that it was rife with propaganda that emphasized the dominance of Roman society, its importance, and its values such as duty and honor.Caesar sought to restore tradition to Rome and remind its citizens of its history at a time when this was important to the continued prosperity of Rome under new rule. Aeneas was used a vessel for examining these functions of propaganda and his journey reinforced these virtues. In effect, Virgil â€Å"draws certain parallels to achieve one of his many political aims-constructing a national identity for Rome as glorious and ancient as that of Greece† (Bell 228). Virgil offered a new perspective on the Trojan War, immediately dispelling the Achaeans as scum for their trickery, which reinforced the dominance of the Trojans.He allowed Aeneas to survive the Trojan War, and used the gods and goddesses that were integral to Roman religion to create a destiny where it was his d uty to found Rome and bring about its prominence, despite not being entirely aware that this was his fate. Due to this, Aeneas embodies the ideal Roman citizen, much as Odysseus embodied the ideal Greek individual. He is filled with duty and honor and not giving up in a time of strife, as when he loses his home of Troy.This is compared to the society of Rome at the time of writing, which was under new leadership and government, and emphasized the importance of society remaining strong and prosperous. Duty to the gods was emphasized through Aeneas and his support from Juno, who reminded him that he has to continue on despite finding love in Dido. The importance of Roman society is examined when despite being injured in combat, Aeneas is able to recover due to the interference of Venus, and was gifted a shield that depicted the future of Rome.In the scenes on the shield, Julius Caesar can be seen, as well as the Battle of Actium, and several other key events known at the time of writi ng to be integral to the history of Rome and all of which would be a direct result of the duty that Aeneas was to serve through his piety. Virgil was effectively able to create a politically driven and supported example of propaganda through his writing of The Aeneid, and the significance of its creation led to a more unified Rome which benefited Augustus Caesar in his rule and cemented Virgil is the annals of history as a great epic poet.Propaganda was a useful tool for both Homer and Virgil, and both men were able to use it in effect to instill and remind the audiences of The Odyssey and The Aeneid of the dominance of the Ancient Greek and Roman societies as well as their values and traditions that remained deeply rooted in each society until the downfall of the respective civilization.
