Observation of Different Photons when Elements are Heated Introduction: The bright line spectrum is the range of colorful lights that are emitted from an atom in its excited state. A “normal” atom‚ or an atom in its ground state‚ is when all of the atom’s electrons are in their proper energy level. When an atom is in its excited state‚ electrons jump to different energy levels making them unstable. As the electron tries to get back to its respective energy level‚ energy is emitted in the form

2HAB=?A Finite Element Analysis was developed as a numerical method of stress analysis‚ but now it has been extended as a general method of solution to many complex engineering and physical science problems. As it involves lot of calculations‚ its growth is closely linked with the developments in computer technology. Now-a-days a number of finite element analysis packages are available commercially and number of users is increasing. A user without a basic course on finite element analysis may produce

summarize the poem about a boy nervous about his first time with a girl. So they walk to a drugstore so he can’t treat her with something from there.

While this was happening he preceded to look outside and notice all the small and grim details about December‚ he then eats the second orange

Rare Earth Elements in the United States Recently‚ international events have brought attentions to the rare-earth elements. Issues surrounding China’s embargo on rare-earth elements exports have raised major concerns among the heavy buying countries around the world that rely on these resources. China currently dominates the global rare-earth production and exports of the international marketstrade. Devastating impacts may arise if China places a long-term embargo on its rare-earth elements export

silver-white chemical element discovered in 1886 by a French scientist named Paul-Émile Lecoq de Boisbaudran. It wasn’t isolated until a different separation technique (ion-exchange) developed in the 1950s by a Canadian scientist Frank Spedding and his team. This rare element it is never naturally found. It is only made chemically. It can be found in minerals such as xenotime. Dysprosium is a member to the lanthanide family on the periodic table just like all the other rare elements. Shown in Fig.1 is

The Environmental Impact 95 percent of electronic waste is recyclable. However‚ unregulated recycling can cause more harm to the environment than landfilling. While many companies‚ such as Apple‚ have safe and effective recycling programs‚ the majority of recycling companies export some percentage of their electronic waste to China or poor countries in Africa‚ where the waste is “recycled‚” or destroyed and stripped of its valuable metals. Though this seems like a good thing on the surface‚ because

Nickel and Dimed: On (Not) Getting By in America | March 29 2009 A riveting tale about the world of low class workers‚ Ehrenreich puts into words what most are don’t acknowledge or are afraid to acknowledge. Through first-hand experience‚ Ehrenreich successfully navigates her way through the low wage work by working such common low wage jobs as waitressing‚ housecleaning‚ and sales. While along the way discovering that each job encompasses their own organizational structure‚ culture‚ and

After reading Nickel and Dimed and reviewing the NASW Code of Ethics I found a few parts of the code of ethics Ehrenreich did not follow. I believe she was in breach of privacy and confidentiality‚ dishonesty‚ fraud‚ and deception‚ and integrity. Privacy and confidentiality is a very important aspect of social work. Although Ehrenreich changed the names of her coworkers and places she worked at‚ she still disclosed private information about them they may not have wanted the entire world to know

Nickel and Dimed Barbara Ehrenreich used her book Nickel and Dimed to illustrate her job assignment to live in the shoes of and‚ write about her experiences as a minimum wage worker in America. Ehrenreich goes to live in Key West‚ Maine‚ and Minnesota and works low wage jobs‚ sometimes more than one at a time. The point Ehrenreich is trying to make is that it is almost impossible to live a decent life in America with one‚ let alone two jobs paying very low wages. It is tough to be a low wage
