Heart valve replacements are more common than most people think. In the United States it is said that over 99‚000 heart valve surgeries are performed yearly. The majority of the valve replacement surgeries are to replace or repair the mitral or aortic valve‚ since the left side of the heart works harder than the right. There are several types of valve disease‚ the two most common are valvular stenosis and valvular insufficiency. Valvular stenosis occurs when the opening of the valve is smaller

What Valve does differently to manage and motivate people is basically by having no managers. Valve lets their employees pick their own projects they want to work on. Since Valve is a ‘Flatland’‚ employees pick which projects they want to help work on and can even be recruited by other employees to work on a project with them. You can even move your desk around to different places to work with different people on different projects. They motivate their employees by letting them be creative and

Heart Valve Transplants The heart‚ the most important organ in the body‚ plays a vital role in a supplying the body with all of the nutrients needed. Not only does the heart pump blood through the body‚ but it also carries oxygen to help the body function correctly and it allows for the removal of waste product. Because the heart is so essential to human body‚ its structure and function is equally as important. The heart is designed to pump blood through its chambers. The top two chambers

States alone. Essentially it is a faulty heart valve‚ particularly the mitral valve (hence the name). Because of this valve’s malfunction‚ when the heart normally contracts to pump blood through the body‚ the mitral valve slips back into place too fragile. In direct opposition to this condition is mitral valve stenosis that is when the mitral valve is too rigid and not flexible enough. Basically‚ the problem with mitral valve prolapse is that the mitral valve is just too flexible. While the

CEE 320 Fluid Mechanics Lab Head Loss Through a Valve April 24‚ 2012 Abstract This experiment determined the relationship between the head loss through a gate valve and the degree of opening of that valve with varying flow rates. The objective of this experiment was to determine the valve loss coefficient‚ K‚ for a specific gate valve as a function of both the pipe Reynolds Number‚ and the degree of opening. The relationship between the Reynolds Number and the friction factor was
