Rutherfordium Facts - Rf or Element 104 Facts

The element rutherfordium is a synthetic radioactive element that is predicted to exhibit properties similar to those of hafnium and zirconium. No one really knows, since only minute quantities of this element have been produced to date. The element is likely a solid metal at room temperature. Here are additional Rf element facts: Element Name:Â  Rutherfordium Atomic Number: 104 Symbol: Rf Atomic Weight: [261] Discovery: A. Ghiorso, et al, L Berkeley Lab, USA 1969 - Dubna Lab, Russia 1964 Electron Configuration: [Rn] 5f14 6d2 7s2 Element Classification: Transition Metal Word Origin:Â  Element 104 was named in honor of Ernest Rutherford, although discovery of the element was contested, so the official name was not approved by the IUPAC until 1997. The Russian research team had proposed the name kurchatovium for element 104. Appearance: Rutherfordium is predicted to be a radioactive synthetic metal, solid at room temperature and pressure. Crystal Structure: Rf is predicted to have a hexagonal close-packed crystal structure similar to that of its congener, hafnium. Isotopes: All of the isotopes of rutherfordium are radioactive and synthetic. The most stable isotope, Rf-267, has a half-life around 1.3 hours. Sources of Element 104: Element 104 has not been found in nature. It is only produced by nuclear bombardment or decay of heavier isotopes. In 1964, researchers at the Russians facility at Dubna bombarded a plutonium-242 target with neon-22 ions to produce the isotope most likely rutherfordium-259. In 1969, scientists at the University of California at Berkeley bombarded a californium-249 target with carbon-12 ions to produce alpha decay of rutherfordium-257. Toxicity: Rutherfordium is expected to be harmful to living organisms due to its radioactivity. It is not an essential nutrient for any known life. Uses: At present, element 104 has no practical uses and is only application to research.

From Working Poor For Elite Scholar Essay - 1958 Words

4 SAMPLE GRADUATE SCHOOL ESSAYS #1. From Working Poor to Elite Scholar One of the proudest accomplishments of my life was earning my college degree, despite the fact that my early adulthood pointed in the opposite direction, beginning with my marriage at the age of 19. Throughout the 1990s I lived as one of the working poor, someone who slipped through the cracks of supposedly historic prosperity. By the age of 25 I was divorced and frustrated with menial, low-paying jobs: clerk, receptionist, and housecleaner. There is nothing like scrubbing someone else s toilet to inspire one with determination toward obtaining an education. Because of my absolute commitment toward earning my degree, I got a flexible shift at a retail warehouse which enabled me to acquire my degree while supporting myself financially. Enrolled at the local community college, I experienced a different world opening up to me; excited by a new encouraging environment, I excelled academically. I learned that if I tried hard, I could succeed; if I wanted something badly enough, I possessed the ability to take advantage of these opportunities. I worked a minimum 35-hour workweek for five years to put myself through school without succumbing to the temptation of a student loan. I paid tuition up front with the money I earned. It was the example of my mother, a Puerto Rican immigrant working diligently to provide for her family, who instilled a work ethic into me that has stood me in good stead.

Will You Please Be Quiet, Please free essay sample

?â€Å"Will You Please be Quiet, Please† is a short story collection that explores the human condition in the blue collar, working class citizens of the 1960’s in America. Carver is known not only for his minimalist style of writing, but also for his habit of basing many, if not all, of his stories on his own real life experiences. In this collection, Carver shows modern life as a series of hardships whereby ordinary people, who have the odds stacked against them, must battle for survival. He explores this idea in many of his stories, using themes such as a consistent pattern to which he creates his males characters, the effects of worldly events that are not explicitly named nor even mentioned, and the failure of the American Dream. Carver consistently creates male characters from the same basis of personality. Each of his characters are dissatisfies with their existences, and many of his characters feel isolated and alone. This feeling of failure and helplessness closely resembles Carver’s own self-professed feelings during his first marriage after the first ten happy, ‘idealistic’ years. Carver creates characters that reflect himself, hence why characters such as the presumed ‘Mr Slater’ in ‘Collectors’ is dealing with what seems to be the aftermath of a devastating divorce. Carver writes ‘Mr Slater’ as lost, alone and without purpose, shown by his constant twice of looking ‘through the curtain for the mailman. ’ This shows that the passage of time for this man is marked by nothing other than the comings and goings of the mailman. Further showing this sense of helplessness that proves Carver’s idea that ordinary people must struggle for survival, is the underlying message of the story ‘Collectors’, which refers to the loss of personal identity. Imagery such as the vacuum cleaner sucking up the ‘little bits of ourselves’ that are left each night on a mattress, shows the character Aubrey Bell slowly taking away what is left of ‘Mr Slater’s identity. ‘Mr Slater’ is struggling to stay afloat after his divorce, but the odds are stacked against him, as Aubrey Bell later takes a letter for a ‘mr slater’ and says that he’ll ‘see to it. ’ The presumed ‘Mr Slater’ of this story has lost his battle of survival against the odds stacked against him, as Carver presumably believed he had after his divorce with his first wife. In the short story collection, ‘Will You Please be Quiet, Please? ’ Carver portrays modern life as a series of hardships whereby ordinary people, who have the odds stacked against them, must battle for survival. As Carver heavily based his work upon experiences of his own life, it can be assumed that the ‘odds stacked against them’ refers to elements outside of the characters control, such as the economic situation of America in the 1960’s. The poorly state of the American economy was a direct result of the Cold War, which occurred during the 1960’s. The Cold War was a stalemate between Russia and America, with each country aiming nuclear weapons at the other, yet neither firing. As each country had to majorly increase production of these nuclear weapons, a huge chunk of the country’s budget was spent on this cause, leaving less money for America’s other needs. The state of the economy, although not explicitly mentioned, is apparent especially in the story, ‘Jerry and Molly and Sam’ in which the company Al is employed by is ‘cutting back. ’ According to Al, ‘no one is safe’ from these cut backs due to the company attempting to reduce costs. As is apparent in Jerry and Molly and Sam, the impending loss of a job can result in many problems, most of which replicate problems faced throughout Carver’s own life. A theme consistently broached by Carver, is the theme of the Failure of the American Dream. The American dream, an ideology brought on by the economic boom after world war two in America, was a standard to which all working class families strived to live up to. The American Dream conveyed the idea that anyone can have this level of happiness, provided they work for it, and each fit into their socially accepted roles. However, this American dream frequently failed working class citizens, as elements outside of their control such as the economic state during the cold war and the American involvement in the Vietnam war, each individually impacted their ability to achieve this happiness. The failure of the American dream is especially apparent in the story ‘Neighbours’ in which Bill and Arlene Miller consistently compare their lives to that of Jim and Harriet Stone. Bill and Arlene represent the working class, and Jim and Harriet Stone are white collar workers. When comparing each apartment, Carver uses structural techniques such as a significant lack of describing works when talking about the Miller’s life, and an abundance of describing works used when talking about Jim and Harriet Stones’ life. Another way Carver portrays this theme is through the actions of the characters, such as Bill Miller, always wishing to ‘go to bed’ and make love with his wife, only after immediately returning from the Stones’ apartment. This shows that the white collar lifestyle is an experience that is vastly different and hugely preferable to the blue collar, working class lifestyle. Carver depicts modern life as a series of hardships because, to him who faced mostly all of the hardships portrayed in his stories, it was a battle for survival.

Unconditional Love in I Stand Here Ironing and Everyday Use free essay sample

Ashley Gillette Professor Grimes ENG 171 24 June 2010 Unconditional Love in â€Å"I Stand Here Ironing† and â€Å"Everyday Use† Unconditional love is a term used to describe complete love. It is affection with no limits or conditions (â€Å"Unconditional†). I Stand Here Ironing by Tillie Olsen and Everyday Use by Alice Walker  are stories about a mothers unconditional love toward her daughter. Both stories stem from an intense guilt felt by the mother’s in each story. Both mothers’ feel guilty for the problems that their daughters face. Emily’s mother thought of Emily’s childhood as she ironed. Metaphorically, Tillie Olsen described the mother ironing her daughter’s dress as she mentally attempted to â€Å"iron† out her daughter’s childhood and their relationship. Through a stream-of-consciousness monologue, the reader could sense that Emily’s mother regretted her decision to have the women below their apartment baby-sit Emily while she worked (or looked for a job). We will write a custom essay sample on Unconditional Love in I Stand Here Ironing and Everyday Use or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page She also regretted leaving Emily with her father’s family while her mother worked nights at a job. Most of all, she regretted sending Emily away during her childhood to a convalescent home. In a different way, Mrs. Johnson, the mother of Maggie and Dee in â€Å"Everyday Use,† is guilty in the way she parented her daughters. Dee, or â€Å"Wangero† as she prefers to be called, was educated and successful, while her sister, Maggie, still lived at home in the South with her mother. Because of Dee’s manipulative behavior, Mrs. Johnson worked hard at raising money in order to send Dee away to school. However, Maggie was forced to remain at home and learn traditional skills because Mrs. Johnson only raised enough money to send one daughter. Despite the choices that each mother makes, in the end the reader senses the unconditional love that each have toward their daughter. Emily’s mother described Emily as a beautiful baby. She commented that â€Å"she was a miracle to me† (Charters 671). Although her mother regretted leaving Emily with others while she worked, she had no choice. By working, unconditional love was shown because she worked to provide for Emily, no matter what it cost her. In addition, she gave up her nights of sleep in order to work during the night so that she could spend the days with Emily. Emily’s mother was extremely guilty that she sent Emily to the convalescent home. Although this was not what she wanted for her daughter, a local clinic convinced her that the home will provide her with the â€Å"kind of food and care [Emily’s mother couldn’t] manage for her† (Charter 673). In hopes that they were being truthful, Emily’s mother sent her away – hoping that she would have a better life, despite the pain it would cause her mother. Although in the end, the reader realizes that the clinic that suggested the home were wrong, Emily’s mother did not feel confident enough about her own instinct to challenge their suggestion. Although Emily’s mother was not sure how to nurture and care for Emily after she returned home from the convalescent home, she remembers encouraging Emily to use her developed talent for comedic acting at school. One morning after being encouraged by her mother, Emily took her mother’s advice and entered into a amateur show, to Emily’s surprise, she earned first place. She called to tell her that â€Å"I did it. I won, I won; they gave her first prize† (Charter 675). This is a prime example of unconditional love, even though her mother was lost in what to do for Emily; she still encouraged her to make something of herself. In the moment that she won first place, Emily’s mother stated that â€Å"suddenly she was Somebody† (Charter 675). In the end, Emily’s mother decides to â€Å"let her be† and again shows her unconditional love as she hopes that Emily will come to know â€Å"that she is more than this dress on the ironing board, helpless before the iron† (Charters 676). She hoped that Emily would realize that she is more than her childhood. Although Dee turned out to be the more successful daughter, Mrs. Johnson shows Maggie’s hidden worth and makes it known to Dee when she returns home with her boyfriend. In doing so, Mrs. Johnson stood up for what was right, not in her benefit, but to benefit Maggie. Although Dee wanted the quilts that their mother was saving as a wedding gift for Maggie, Mrs. Johnson refuses to give in. In this moment, for the first time, she hugs Maggie and takes the quilt from Dee’s hand and gives them to Maggie. For once, both daughters sense the unconditional love (which has not been evident) that Mrs. Johnson has toward Maggie. Despite the hardships that each mother faced, each story ended with a glimmer of hope and the realization that unconditional love can move mountains in ones life. Because of each mother’s unconditional love for their daughters, Emily and Maggie, realized their unseen importance. Works Cited Charters, Ann.

Membrane filtration (expriment) Lab Report Example | Topics and Well Written Essays - 1250 words

Membrane filtration (expriment) - Lab Report Example As potable water is procured from surface sources such as rivers, streams and lakes, bacteriological examination is crucial to determine the safety of drinking water. Presence of Enterococcus faecalis, Escherichia coli, Enterobacter aerogens and Proteus mirabilis in water sample was estimated using membrane filtration followed by incubation of the membrane filter in appropriate growth media to examine the determine the presence of pathogenic micro-organism. The motive to perform this study was to determine the presence of unknown organism(s) present in the provided samples. The study encompasses classification of bacteria based on their bio-chemical reactions, pH levels and osmoregulation. Identification and classification of bacteria from the sample is pragmatic as presence of any pathogenic micro-organism could be deleterious to health. Identification of bacteria provides line of treatment. The three preliminary steps for the analysis procedure comprise principal isolation, stainin g and biochemical reactions as the samples may contain diverse microorganism belonging to different species. Hypothesis to be tested: (1) Fecal coliform count of surface water samples differ according to their location. (2) Fecal coliform count of surface water samples do not differ according to their location. Introduction Microbes are indispensible module of our environment. They are associated in a variety of ways with everything we use in our everyday lives (Fratamico, 2005). They are found to be associated with the food that we eat, the clothes we wear/make use of and water we drink/utilize. They may perhaps influence the quality of our lives and transmit numerous diseases (Fratamico, 2005). It is therefore essential to understand the microbes linked with the commodities used in everyday life. Water free from disease-producing microorganisms and chemical substances deleterious to health is called potable water. Water contaminated with either domestic or industrial wastes is cal led non-potable or polluted water. The objectives of primary concern in providing potable water are freedom from harmful microorganisms and from undesirable chemicals. Water appearing clean or free from peculiarities of odor and taste could be contaminated. In such conditions special procedures are required to determine its sanitary quality. Inspection of water sample involves the inspection of the source of raw water and the conditions that may influence its quality. Changes related to population, types of industry and the method of sewage disposal are imperative. Practically, periodic and comprehensive sanitary surveys are necessary. However, potability can be determined only by chemical and bacteriological laboratory tests (Pelczar, 1993). Pathogens that gain entry into the water body include protozoan such as Giardia and Cryptosporidium, bacteria such as Campylobacter, Salmonella and Shigella and virus associated with water contamination are Hepatitis A virus and Norwalk virus. However, water is tested for the fecal contamination. As coliforms are discharged through feces the water sample containing fecal matter comprises pathogenic organisms as well. Essentially water sources such as wells, reservoirs, and storage tanks are routinely tested for water safety (Case Study Exercise 29: Measure of Water Quality: Membrane Filtration Method).
