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

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

QUESTIONS chap12 3. How do the entry and exit of firms in a purely competitive industry affect resource flows and long‐run profits and losses? LO3 Answer: Entry and exit help to improve resource allocation. Firms that exit an industry due to low profits release their resources to be used more profitably in other industries. Firms that enter an industry chasing higher profits bring with them resources that were less profitably used in other industries. Both processes increase allocative efficiency
