Abstract: Atherosclerosis is one of the important cardiovascular disease‚ which often leads to narrowed arteries that obstruct the flow of oxygenated blood which may limit the oxygen delivery to the heart muscle and can lead to a heart attack. The blood flow through these narrow arteries is often restored by inserting folding structures‚ named Stent. A Stent is small expandable mesh-tube like device that is used to treat narrow arteries and allow the passage of oxygenated blood to heart. The aim

sexual assault are 3-5 times more likely to experience PTSD‚ future abuse‚ alcohol or substance abuse‚ and engage in delinquency during adolescence than adolescents who were not abused. They also show symptoms such as emotional outbursts or fluctuation‚ learning difficulties‚ and inappropriate social‚ sexual‚ or emotional behaviors (NIJ‚ 2011). Finkelhor and Browne (1985) examined how traumagenic dynamics play a role in how sexual abuse traumatizes children. Traumagenic dynamics are defined by four

The cardiovascular system consists of the heart‚ blood vessels‚ and blood. This system has three main functions: Transport of nutrients‚ oxygen‚ and hormones to cells throughout the body and removal of metabolic wastes (carbon dioxide‚ nitrogenous wastes). Atria: Ventricles: In a four-chambered heart‚ such as that in humans‚ there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs‚ and the left ventricle pumps

The t-test for dependent groups is a parametric analysis technique used to determine statistical differences between two related samples or groups. Groups are dependent or related because they were matched as part of the design to ensure similarities between the two groups and thus reduce the effect of extraneous variables. For example‚ two groups might be matched on gender so an equal number of males and females are in each group‚ thus reducing the extraneous effect of gender on the study results
