requires an experimental fatigue failure data and a computer aided analysis of these results. A finite element scheme will be developed to simulate the residual stress in weld using the experimental data. A Thermo-elasto-plastic analysis will be used to replicate the butt welded pipe joint and the residual stress will be determined. Residual stress that arises in welded joints by heating and cooling cycles during the welding process is another major factor in fatigue failure of welded structures. Welding

NATURAL DISASTERS A natural disaster is a major adverse event‚ which can cause loss of life or property damage‚ and typically leaves some economic damage. There are many types of natural disasters: avalanches‚ earthquakes‚ volcanic eruptions‚ floods‚ tsunamis‚ blizzards‚ droughts‚ hailstorms‚ tornadoes‚ wildfires. If an adverse event occurs in an area without vulnerable population‚ it will not have such disastrous consequences‚ as if it occurs in area of vulnerable population as in San Francisco

Stress is a term that is commonly used today but has become increasingly difficult to define. It shares‚ to some extent‚ common meanings in both the biological and psychological sciences. Stress typically describes a negative concept that can have an impact on one’s mental and physical well-being‚ but it is unclear what exactly defines stress and whether or not stress is a cause‚ an effect‚ or the process connecting the two. With organisms as complex as humans‚ stress can take on entirely concrete

Disadvantages of genetic modification foods Genetically modified foods are a new kind of food which has been recognized as another food crisis such as mad cow disease in Britain (Sorensen‚ 1999). Since genetically modified foods are becoming more common there is a conflict around the globe to the use of them (Alarie‚ 2000‚ p.19). Moreover‚ there is certain evidence that has been proven the natural process of genetic modification is unsafe and can cause particular health risks (Smith‚ 2009‚ p. 18)

Vulnerable Population and Self-Awareness As of July 1‚ 2013 the United States of America had 54 million Hispanics living within its borders. This equates to 17% of the total population (U.S. Department of Commerce‚ 2014). Many of these individuals do not speak English which creates a language barrier between them and health care workers. This barrier can create biases among health care workers and the Hispanic population. Health care workers may not be able to connect with this population because
