multiple aorto-cardiac cavity communications is very rare but important complication of prosthetic aortic valve endocarditis. the case below illustrates multiple aorto-cardiac cavity fistula formation following prostethic aortic valve endocarditis presented with slowly progressive symptoms of heart failure. a brief review of surgical reconstruction and the existing literature are presented, inc...

Compliance with taking antihypertensive drugs is low amongst patients hypertension. Uncontrolled blood pressure causes heart disease, kidney failure, diabetes, and stroke. It necessary to have alternative support in controlling by using progressive muscle relaxation exercises. This study aimed determine the effect of on reducing The research design used was a literature sample size 20 journals:...

Brain stem potentials from three groups of patients, namely those with pure progressive autonomic failure, Parkinson's disease and multisystem atrophy with progressive autonomic failure (Shy-Drager syndrome) were compared with each other and a group of normal subjects. In virtually all the patients with multisystem atrophy with progressive autonomic failure the brain stem potentials were abnorm...

Probabilistic progressive failure analysis (PFA) is used to predict the life of a Sylramic/MI ceramic matrix composite (CMC) combustor liner in a JTAGG-III engine under both rig and engine conditions. PFA simulations of the combustor liner were made to predict fracture paths and life cycles based on microcrack damage evolution and the contribution of failure modes to total failure. Combustor li...

nowadays, as a result of increased terrorist and bomb attacks throughout the globe in the vicinity of strategic buildings, designing these structures against impact loads, particularly the blast-related ones, has been taken into more consideration. the current procedure for designing the structure against an explosion is a design against the local failure of the current elements in the first st...

Abstract To enable modelling of the progressive failure large, laminated composite components under crash or impact loading, it is key to have a numerical methodology that both efficient and numerically robust. A potential way adopt an adaptive method where structure initially represented by equivalent single-layer shell model, which during analysis adaptively transformed high-resolution layer-...

This study presented a failure analysis of a 52.3 m composite wind turbine blade under static loading. Complex failure characteristics exhibited at the transition region of the blade were thoroughly examined and typical failure modes were indentified. In order to predict multiple failure modes observed in the tests and gain more insights into the failure mechanisms of the blade, a Finite Elemen...

CONTEXT Progressive heart failure is the most common mechanism of death among patients with advanced heart failure. Cardiac resynchronization, a pacemaker-based therapy for heart failure, enhances cardiac performance and quality of life, but its effect on mortality is uncertain. OBJECTIVE To determine whether cardiac resynchronization reduces mortality from progressive heart failure. DATA S...
