COMPLETE PRESERVATION OF MITRAL VALVE APPARATUS VERSUS POSTERIOR LEAFLET PRESERVATION ONLY DURING MITRAL VALVE REPLACEMENT FOR RHEUMATIC MITRAL REGURGITATION

Complete preservation of mitral valve apparatus versus posterior leaflet preservation only during mitral valve replacement for rheumatic mitral regurgitation

Objectives In the present study we investigated whether preservation of both leaflets (anterior and Posterior with subvalvular apparatus) is superior to preservation of the posterior leaflet Alone.Patients and Methods 30 patients who underwent mitral valve replacement in our institute were divided into 2 groups: MVR-C (n=16), in whom both leaflets

Partial Cooperative Equilibria: Existence and Characterization

We study the solution concepts of partial cooperative Cournot-Nash equilibria and partial cooperative Stackelberg equilibria.The partial cooperative Cournot-Nash equilibrium is axiomatically characterized by using notions of rationality, consistency and converse consistency EMUAID MAX with regard to reduced games.We also establish sufficient Spiral

Peculiarities of traction forces in wheel/rail contact area

Tractive force and train movement stability dependence on division of forces involved in wheel/rail contact area are the main subjects of this article.The influence of Spiral Heater Element wheel/rail contact properties in the vehicle dynamics and adhesion fields is investigated.Current tendency all over the world is to reduce the conicity of wheel
