DESIGN OPTIMIZATION OF ENGINE VALVE (PROFILE RADIUS AND DISH PARAMETER) Objective: The main object of this project is to reduce the material from profile radius and dish parameter. This project mainly concentrates on design and analysis of stress‚ buckling analysis‚ fatigue analysis‚ heat treatment condition on wear resistance and comparing the results with the current valve results. Introduction: In order to save material several design principles are explained. These are derived from

“regurgitating” back into the heart‚ a system of one-way valves are present in the heart. The heart valves can be broken down into two types: atrioventricular and semilunar valves. Atrioventricular valves. The atrioventricular (AV) valves are located in the middle of the heart between the atria and ventricles and only allow blood to flow from the atria into the ventricles. The AV valve on the right side of the heart is called the tricuspid valve because it is made of three cusps (flaps) that separate

6. The Mitral valve or tricuspid valve is leaking. The sloshy sound will be heard during the atrial systole. The dub is heard during the ventricular diastole. The chordae tendinae‚ or heart strings‚ support the atrioventricular valve because the heart strings connects the papillary muscles to the tricuspid and mitral valve. 7. The difference between a quintuple bypass surgery and an open heart valve surgery is that the quintuple heart surgery is an open heart surgery‚in which your chest gets crack

CASE CONTROL STUDY A case control study is a method extensively used by the medical profession‚ as an easy and quick way of comparing treatments‚ or investigating the causes of disease. Longitudinal studies are the preferred method‚ but are often expensive‚ time consuming and difficult. Whilst this method does suffer from some weaknesses‚ it is quick‚ and delivers results quickly. The case control study uses groups of patients stricken with a disease‚ and compares them with a control group

REVIEW QUESTIONS FOR CHAPTER 10 1. A case-control study is characterized by all of the following except: a. It is relatively inexpensive compared with most other epidemiologic study designs b. Patients with the disease (cases) are compared with persons without the disease (controls) c. Incidence rates may be computed directly d. Assessment of past exposure may be biased e. Definition of cases may be difficult 2. Residents of three villages with three different

MITRAL VALVE DISEASE MITRAL STENOSIS Mitral stenosis is almost always rheumatic in origin‚ although in the elderly it can be caused by heavy calcification of the mitral valve apparatus. There is also a rare form of congenital mitral stenosis. In rheumatic mitral stenosis‚ the mitral valve orifice is slowly diminished by progressive fibrosis‚ calcification of the valve leaflets‚ and fusion of the cusps and subvalvular apparatus. The flow of blood from left atrium to left ventricle

According to a recent study‚ using a thermostatic mixer valve to reduce the maximum temperature of hot water dispensed from home water pipes should significantly reduce the risk of scalding especially for young children‚ the elderly‚ and people with disabilities. Each year in the United States about 112‚000 people are treated for scald burns in hospital emergency rooms; about 80% of tap water burns occur among young children‚ the elderly‚ and people with disabilities.
