X-ray Documented - Essay Example This means that materials science and engineering operates in a world characterized by high technological advances because technological advancements created from advanced materials. The significance of materials science and engineering started a long time ago. It has existed for many years. Nowadays, people only look at the names of eras and realize that materials have been helpful in the creation of civilization. These eras include the Stone Age, the Bronze Age and the Iron Age. In fact, people have branded the current era as the material era because of the contribution that material engineering has provided. X-rays use materials that are provided by the technology in material science and engineering. The history of the development of science and technology has always been directly linked to the progress of materials science and engineering. In recent times, the expansion of concentration in the surface qualities of solids has become a feature of this field of knowledge. Neverthele ss, it is not surprising that interactions with material are realized through the free surface of the materials. Surface layers can unfalteringly control the application of the whole quantity of material. The free surface is essential for a large amount of material and mechanical features of materials that include yield strength, proportionality limit and material behavior in processes of fragile and low energy fracture (Sham 1012). The concept of X-rays was first discovered by a physicist from Germany called Wilhelm Roentgen in 1895. However, A.W. Goodspeed was the first person to make the X-ray discovery, on February 22, 1890. Because there was no information that could prove that he had discovered X-ray, Goodspeed named his discovery an accident and did not take any credit for the work he had done (Dyson 1). In the discovery, Wilhelm enclosed a glass tube inside of a black paper box. He attached a wiring that ran inside the glass tube that resembled the inside of a light bulb. Th is enabled the electrical currents to build up in the glass tube. He then connected the tube to an induction coil apparatus that allowed an electric current to pass through the tube. This way, a faint green colored light could be seen across the room. He decided to do this in a different way to be sure of what he had seen. He lit a match stick and discovered that there was a small screen in the room which was coated with a chemical. The lighting from the match stick sent the current along the tube. This made the exact same light to appear again. As he continued with his experiments, he discovered that these rays could penetrate through objects, such as wood and metal. Accidentally, his hand came in contact with the tube one day, and saw shadows of his hand with darker shadows that represented the bones. When he moved his hand, the shadow on the screen also moved. He named the shadow the first x-ray picture (Lewin, Paradijs and Heuvel 373). X-ray works in a unique way. As the wavelen gths of light diminish, they augment in terms of the energy that is produced. X-rays have lesser wavelengths, which cause higher energy compared to ultraviolet waves. This is the reason as to why professionals consider X-rays with respect to the energy they produce rather than their wavelength. This is partly because X-rays have minute wavelengths. Another reason is because X-ray light works like particles as opposed to waves. X-ray detectors gather definite photons of X-ray light that are remarkably different from the radio telescopes that contain large tableware designed to focus radio waves. When an X-ray of a person’s body is done in a hospital, professionals put X-ray sensitive films on one side of the patient’

Human survival Essay Example for Free

Human survival Essay Wilson highlights the effects that the Homo sapiens have brought about in the world through what he refers to as a geophysical force, ranging from causing changes in the climate and the atmosphere to the modification of the fauna and flora. Besides, he reckons that in the history of evolution, it is only the human species that has tenuously advanced the complete mass in protoplasm. His claim that the human species’ destructive habits are maintained in their hereditary traits is credible. Apart from being tribal and assertively territorial, this species is oriented by selfish reproductive and sexual drive. Our actions lead to water and air pollution, lowering of the water tables and extinguishing of other species. The human’s nature juggernaut theory moreover explains why global responsibility comes last since the genetic heritages have led to humans being egocentric. They swiftly react to daily life minor problems and conflicts but inhumanly to similar magnitude status and tribal security challenges (Wilson, 1996). However, due to the exponential development in human populace and technology, the young generation has become more environmentally concerned than the older. Since they are in pursuit of better standards of living, they have intensified their scientific knowledge. This advancement has however led to more environmental destruction. Since humankind possesses intelligence and spirit, it has survived the ecological laws. However, these are not adequate to free this species from the natural environment’s constraints such as the almost exhausted resources and deteriorating atmospheric chemistry (Wilson, 1996). To free ourselves from the suicidal accusations, we ought to keep off civilization dimensions that are a threat to the environment. We have to be ethical so as to protect our self-images. In various arenas, environmental issues are being addressed as a moral issue and this will aid safeguard the surroundings. Even demographic statistics have reflected positive responses to this issue. With these signs of stabilizing the global environments, chances of preserving the ecosystems that are surviving and micromanaging them for the benefit of humankind remain strengthened.

Fredrick Douglas Essay -- Biography Biographies Slavery Slaves Essays

Fredrick Dougalas Is it possible for one of our times, living in the free United States, to be bonded in the institution of slavery? One hundred and fifty years have past now since slavery was abolished. The institution of slavery kept the deprivation of women legal and the learning of the mind illegal. Among the slaves, there could be no men, or else that slave would not be a slave. Frederick Douglas existed among slavery only to later on escape and gain his freedom from those who oppressed and enslaved him. The masters of slaves were determined to keep their slaves ignorant so that they would not even think of freedom or the joys it. Slaveholders tried to keep their slaves happy, but yet under their control. Douglas would not stand for this. It was his intelligence, bravery, and determination that made Frederick Douglas a man and not a slave. Frederick Douglas was born and raised a slave. He had no other life in his youth. The harsh conditions of the institution forced Frederick to crawl into a bag at night and sleep on the cold ground with his head in the bag and his feet outside of it. This form of sleeping led his feet to be cracked with frost so badly that one could stick a pen into the gashes. Douglas and the other slaves were not fed a regular allowance of food. Him and the other children were called and eat coarse corn meal from a large wooden tray that was put on the ground. The children would be forced to eat like pigs gathered around left over mush. At the age of seven or eight years old, Frederick left Colonel Lloyd’s (a prominent slaveholder) plantation to live in Baltimore, Maryland with Mr. Hugh Auld. Mr. Auld was a man who had never bonded a slave and knew very little of the keepings of them. Neither did his wife, who (without the knowledge of its repercussions) taught Frederick how to read. After Mr. Auld forbade his wife to teach Douglas, Frederick decided he would learn anyway. He tried to read newspapers and was forbidden. Whenever Frederick was left alone, he would attempt to read only to have Mr. Auld come and snatch away whatever reading material he had. The little that Frederick was taught was enough for him to go into the streets and receive his lessons from the boys whom he was acquainted with. Though Mrs. Auld refused to teach him, Douglas was determined to learn and he did. Determination was the firs... ...me that turning point in his career as a slave. It revived his sense of manhood. Douglas was determined to live a free life. He tried to escape from bondage not once, but twice. After betrayal the first time, Douglas was sent to the city once again to live with the Auld family. Douglas picked up a trade and worked to gain wages. He devised a plan where he would contract his time and would pay Mr. Auld six dollars a week to allow him to do this. He would allow Mr. Auld to trust that he would not run away. He did this by working hard and giving Mr. Auld all of his wages. He would make Mr. Auld very happy and content with this agreement. At the height of this, Douglas escaped bondage. He was able to outwit his master and escape from the hells of slavery. Among the slaves, there were few who one could point out to be men for they lacked the intelligence, determination and bravery. Douglas was able to open his eyes and see that this life was not right. He viewed slavery as the greatest evil of his time. His successful escape proved him to be the man that a slaveholder could never keep.

Ethical Dilemma: Donna and Wilma Essay

Abstract In this paper, you will be able to see how to apply professional values, codes of ethics, and decision-making model to the process of ethical decision-making. I chose to look at ethical dilemma number 4. In this dilemma, a client’s confidentiality has been breached; due to her counselor. The first approach is for me to identify the problem and apply the ACA code of ethics. I then identify the moral principles and list all possible courses of action that could betake. Also list all possible consequences for each action that could be taken. I then carefully review, after which I chose what I believe to be the most accurate course of action for this scenario. So lastly I will take you step by step of how this action plan will be implement. Ethical Dilemma I chose to review ethical dilemma 4. Where Wilma, a counselor in a community agency, has been working with Donna for several months for anxiety and panic disorder. On multiple occasions, Wilma has given Donna homework to complete between sessions that has not been completed by Donna. This past week, Wilma sees Donna again in session and assigns her some more homework. Later that week, Wilma and a friend go out to dinner. Wilma looks up to see that Donna is her waitress. Frustrated with Donna’s lack of effort with her homework and in an effort to hold Donna accountable, Wilma decides to inquire if Donna has done her homework and says, â€Å"Donna, I am glad I ran into you. Have you done your homework since our last session?† I chose to review this particular ethical dilemma because this is something that could easy happen to any professional, if you fail to think before you speak. It can even be done with no ill intentions. However this could possible destroy the client and counselor relationship that has been built. The problem with this hypothetical ethical dilemma is that the client’s confidentiality was broken and relationship boundaries were crossed. This is an ethical and possible a  legal problem. It is an ethical problem because the clients confidentiality was broken when Wilma inquire if Donna had been working on her homework from their last session. It can also become a legal issue if Donna pursues it. This can become a major problem as it relates to the Wilma and the agency that she works for because the client’s confidentiality was broken. Donna could contact the agency that Wilma is employed for, or even contact the state board of counselors. The ACA code of ethics covers any ethical issues that a counselor maybe faced with. While reading over the ACA code of ethics confidentiality privileged communication and privacy was coved in great detail. Respecting Client Rights was defined as â€Å"counselors maintain awareness and sensitivity regarding cultural meanings of confidentiality and privacy. Counselors respect differing views toward disclosure of information. Counselors hold ongoing discussions with clients as to how, when, and with whom information is to be shared† (Ethics & Professional Standards, 2005). In the case with Wilma and Donna , Wilma was not sensitivity regarding Donna’s privacy. Wilma was having dinner with a friend and Donna was at work. That was not the right time to address anything that they had coved in a counseling session. According the ACA codes of ethics Wilma did not have respect for privacy or respect for confidentiality for her client. The ACA code of ethics defines respect for privacy as â€Å"Counselors respect client rights to privacy. Counselors solicit private information from clients only when it is beneficial to the consoling process† (Ethics & Professional Standards, 2005). It is also stated that respect for confidentiality â€Å"Counselors do not share confidential information without client consent or without sound legal or ethical justification† (Ethics & Professional Standar ds, 2005). I believe that it a counselor’s main moral principle is loyalty to their clients and honoring their commitments to them. In this case Donna believe that anything that was discussed in their counseling sections would remain confidential. â€Å"There are state and national organization That work to assist clients and professional counselors in taking the appropriate legal and ethical steps. The American Counseling Association provides free confidential professional/ethical consolations to members of the ACA. If a counselor is advice they van contact the ACA Ethics and Professional  Standards Department to set up appointments. Counselors can also contact their state LPCA to receive information regarding the proper protocol for certain cases† (Ethics & Professional Standards, 2005). There are several potential course of action in this case. Any course of action that would be taking would be fully up to Donna in this case. Donna could ignore the comments that Wilma made to her. Donna could talk to Wilma, and express that she didn’t appreciate how she addressed her personal issues in front of a stranger and while she was at work. Also let Wilma know she would appreciate if she wouldn’t do that again. After Donna address this issue with Wilma she could chose to keep her as her counselor or ask for a new counselor. Donna could also consult another counselor to determine the best course of action to take against Wilma. Lastly, Donna could contact ACA for legal and ethical advice regarding breach of confidentiality. For each potential course of action there is a potential consequence(s) and implications for each chose. If Donna choses to ignore the comment that Wilma made to her, there will not be any consequence for Wilma. However there could be potential consequences and/or implications for Donna. If Donna ignores the comments, Wilma may keep to making statements. If Donna talks to Wilma, and express that she didn’t appreciate how she addressed her personal issues in front of a stranger and while she was at work, this could help. The consequences of this course of action could be beneficial to both Donna and Wilma. It could be beneficial to both parties, Wilma will see that she breached her clients confidentiality and Donna will have the chance to express how that made her feel. This could help rebuild the trust that was lost do to Wilma’s lack of professionalism; it could also help Donna with her anxiety. If Donna consults another counselor to determine the best course of action, this could be very important in this case. By discussing this with another counselor can help Donna gain a better insight as to how to handled and move forward with treatment. Lastly if Donna contacts the ACA board for legal and ethical advice, this could have major consequences for Wilma and the agency. Wilma will most likely be fined or even have her licenses revoked. I believe that the best course of action in this case would be for Donna to talk Wilma, and express that she didn’t appreciate how she addressed her personal issues in front of a stranger and while she was at work. I believe this is the best course of action only because Wilma did not go into detail  about what the homework consisted of. Although Donna confidentiality was breached, no significant information was exposed, other then the fact that she sees a counselor. I don’t believe that is would be necessary for any legal action to be taken. I do believe that Donna should inform another member of the agency of what happened and the course of a ction that she has chose to take in dealing with dilemma. The selected course of action does not present any new ethical problems in my eyes. I believe that Donna has covered herself in all areas. If Donna talks to Wilma and also consult another counselor in the agency, this should eliminate any potential ethical problems. After reviewing all possible courses of actions and consequences, I believe the most beneficial option would be to for Donna to talk Wilma, and express that she didn’t appreciate how she addressed her personal issues in front of a stranger and while she was at work and consult another counselor in the agency. I applied the test of justice, publicity, and universality here are my findings. Justice: In this case choosing to consult Wilma with this dilemma it will help Wilma be more aware of confidentiality of her clients. Publicity: In the public eye Wilma is not acting ethically. Universality: The course of action that Donna has chosen (addressing Wilma and consulting another counselor in the agency) would be a great recommendation for other people put in similar situations. There are certain steps that Donna has to take in order to implement this course of action. First, Donna needs to consult the other counselor that works for Wilma agency. Donna should have a sit down conversation with this person and go over each detail of the event that happen on the night she was working. Also Donna should express the course of action that she wants to take to handle this case. Lastly Donna, Wilma and the counselor that Donna informed of the incident should all have a sit down conversation. Donna can then explain to Wilma how she felt and the lack of professionalism. Wilma and Donna are both being protected in this case because there is a three person there to over see the conversation and take notes that can go into Wilma and Donna records.

Republic of India

India, officially the Republic of India (Bharat Ganrajya), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country with over 1. 2 billion people, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the south-west, and the Bay of Bengal on the south-east, it shares land borders with Pakistan to the west;[d] China, Nepal, and Bhutan to the north-east; and Burma and Bangladesh to the east.In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; in addition, India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia. Home to the ancient Indus Valley Civilisation and a region of historic trade routes and vast empires, the Indian subcontinent was identified with its commercial and cultural wealth for much of its long history.Four world religions—Hinduism, Buddhism, Jainism, and Sikhism—originated here, whereas Judaism, Zoroast rianism, Christianity, and Islam arrived in the 1st millennium CE and also helped shape the region's diverse culture. Gradually annexed by and brought under the administration of the British East India Company from the early 18th century and administered directly by the United Kingdom from the mid-19th century, India became an independent nation in 1947 after a struggle for independence that was marked by non-violent resistance led by Mahatma Gandhi.Rabindranath Tagore is Asia's first Nobel laureate and composer of India's national anthem Swami Vivekananda was a key figure in introducing Vedanta and Yoga in Europe and USA, raising interfaith awareness and making Hinduism a world religion. The Indian economy is the world's tenth-largest by nominal GDP and third-largest by purchasing power parity (PPP). Following market-based economic reforms in 1991, India became one of the fastest-growing major economies; it is considered a newly industrialised country.However, it continues to face the challenges of poverty, corruption, malnutrition, inadequate public healthcare, and terrorism. A nuclear weapons state and a regional power, it has the third-largest standing army in the world and ranks eighth in military expenditure among nations. India is a federal constitutional republic governed under a parliamentary system consisting of 28 states and 7 union territories. India is a pluralistic, multilingual, and a multi-ethnic society. It is also home to a diversity of wildlife in a variety of protected habitats.

Free Essays on Anthropology

Anthropology proves to be satisfying and intellectually fulfilling to many in the field. However, there are also many challenges and bumps in the road along the way. Napolean A. Chagnon and Claire Sterk faced many of these challenges themselves. During his fieldwork with the Yanomamo, Chagnon faced many challenges interacting with the natives. Chagnon could not practically communicate with the people until about six months after he arrived. He notes ? the hardest thing to live with was the incessant, passioned, and often aggressive demands they would make.? An example of this is the natives threatening with a shout such as; ?If you don?t take me with you on your next boat trip to Widokalyateri, I?ll chop a hole in your canoe!? While trying to collect genealogies, Chagnon found it very frustrating and commented ? I could not have deliberately picked a more difficult people to work with in this regard.? This was because he first tried to use the names they called each other, not knowing that the names they called each other were completely ambiguous and didn?t mean anything. He then later found out , after collecting all the genealogical information, that only the living members were accurate and the deceased listed were mostly fake. He had to start all over. ( Chagnon 5) Sterk did a different type of study on prostitution and how it went on during a time when AIDS was a major problem. This type of fieldwork is ethnographic fieldwork. Sterk had to get established in rough neighborhoods, crack houses, and sidewalks of busy streets. She first and foremost had to locate her samples by asking local taxi-drivers, bartenders , and AIDS clinics. Developing a relationship and trust with women who had never had any trustworthy people in their lives was quite challenging as well. Sterk was once followed home by one of the woman?s pimps and his friends, and was jumped. The woman admitted to Sterk ...

Free Essays on Anthropology Anthropology concerns itself with humans as complex social beings with a capacity for language, thought and culture. The study of anthropology is about understanding biological and cultural aspects of life among peoples throughout the world. All humans are born with the same basic physical characteristics but, depending on where they grow up, each individual is exposed to different climates, food, languages, religious beliefs, and so on. However human beings are not simply shaped by their environment, they also actively shape the world in which they love. A key aim of anthology is to understand the common constraints within which human beings operate as well as the differences which are evident between particular societies and cultures. Given such concerns, the potential subject matter of anthropology is truly vast. Researchers nowadays tend to specialise on in or another branch of the discipline. Some, called physical or biological anthropologists, investigate such topics as how humans or human-like creatures evolved over thousands or millions or years, as well as our genetic and behavioural relationships with non-human primates. Others, called social or cultural anthropologists, study such things as the very varied ways in which different peoples organise themselves to ensure stable agricultural production or community life. They might study different assumptions people hold about how the world works as revealed in their religious beliefs and practices. They might study the many material forms that people produce such as their houses, dress, crafts and art. In this Guide we discuss both of these kinds of anthology, although we say more about the social and cultural side of the discipline. Where can I study anthropology? Social anthropology is currently taught to degree level in about 27 UK universities or their constituent colleges. It may be studies as part of a wider degree in so other universities; it may also be studied part-t... Free Essays on Anthropology Hunting and Gathering VS Agriculture From the early prehistoric society until now, we often heard the word â€Å"adaptation†, which means the process of changing something or changing our behavior to deal with new situations. The ways people adjust their natural environment varies according to time, place, and tribe. Foraging is common way of adaptation that people uses for most of human history; however because of the population pressure, some people adopt agriculture to fulfill their need. This essay, will discuss the positive and negative aspects of life in hunting and gathering societies compared to the agricultural societies based on Martin Harris’ article â€Å"Murders in Eden† and Jared Diamond’s article â€Å"The Worst Mistake in the History of Human Race.† Hunting and gathering is the longest-lasting lifestyle for most of human history. In addition to their way of life, hunter-gatherers are often regarded as â€Å"nasty, brutish, and short † (Diamond 114). Progressivists also suggested our hunter-gatherer ancestors adopt agriculture because of â€Å"its efficient way to get more food for less work†(Diamond 114). However, as archaeologists observe in some aspects of their lives, hunter-gatherers societies are not necessarily â€Å"nasty, brutish, and short.† Some issues that we need to compare between hunting and gathering and agricultural societies include workloads, nutrition, production, starvation, infanticide, health and disease, and differences in wealth. From the work loads, it shows that in the barren environment of the Kalahari dessert, the present day Bushmen need only 12 to 19 hours per week to obtaining a diet rich in protein and a high nutritional standard, while their farmer neighbors, the Hadza nomads of Tanzania, need 14 hours per week and get less protein. It also takes more additional hours of food preparation to make it is suitable for consumption. It appears that hunter-gatherers have more leisure time than farm...

Swedish Patronymics and Surnames Explained

Swedish Patronymics and Surnames Explained Until the turn of the  20th century, family surnames were not in common use in Sweden. Instead, most Swedes followed a  patronymic naming system, practiced by about  90–95% of the population.  Patronymics (from the Greek  pater, meaning  father, and  onoma, for name)  is the process of designating a surname based upon the given name of the father, thus consistently changing the family surname from one generation to the next. Using Gender Distinction In Sweden,  -son or -dotter was usually  added to the fathers given name for gender distinction. For example,  Johan Andersson would be the son of Anders (Anders’ son) and  Anna Svensdotter the daughter of Sven (Svens’ dotter). Swedish sons names are traditionally spelled with a double s- the first s is the possessive s (Nils as in Nils son) while the second is the s in son. Technically, names that already ended in s such as Nils or Anders should have three ss under this system, but that practice wasnt often followed. It is not uncommon to find Swedish emigrants dropping the extra s for practical reasons, to better assimilate into their new country. Swedish patronymic son names always end in  son, and never sen. In Denmark the regular patronymic is sen. In Norway, both are used, although sen is more common. Icelandic names traditionally end in son or dotir. Adopting Nature Names During the latter-half of the 19th century, some families in Sweden began to take on an additional surname to help distinguish them from others of the same name.  The use of an extra family surname  was more common  for people who moved from the countryside into the city where long-term use of patronymics would have  resulted in dozens of individuals with the same name.  These names were often a composition of words taken from nature, sometimes called nature names.  Generally, the names were made up of two natural features, which may or may not have made sense together (e.g. Lindberg from lind for linden and berg for mountain), although sometimes a single word would make up the entire family name (e.g. Falk for falcon). Sweden passed the Names Adoption Act in December  1901, requiring all citizens to adopt heritable surnames- names that would pass down intact instead of changing every generation. Many families adopted their current surname as their hereditary family surname; a practice  often referred to as a frozen patronymic. In some cases, the family just chose a name they liked- such as a nature name, an occupational surname related to their trade, or a name they were given in the military (e.g. Trygg for confident). At this time most women who were using patronymic surnames ending in -dotter changed their surname to the male version ending in -son. One last note about patronymic surnames. If you are interested in DNA testing for genealogical purposes, a frozen patronymic does not generally go back enough generations to be useful for a Y-DNA surname project. Instead, consider a geographical project such as the Sweden DNA Project.
