1269 We appreciate the interest of Siondalski et al. [1] and his group beside numerous other international groups in working on autologous aortic valve prosthesis. We experienced tremendous interest, especially in countries where patients need a priceless and reliable bioprosthesis without the need for anticoagulation and with advantageous hemodynamics especially in the smaller sizes. Siondalsk...

Optimal linear controllers and high computational non-linear controllers are normally applied to control the nonlinear systems. Flatness control method is a control technique for linear systems as well as nonlinear systems by static and dynamic feedback namely as endogenous dynamic feedback. This method takes into account the non-linear behavior of the process while preventing complicated compu...

Woldenberg Village, an aging-in-place residential facility, is the result of 2 years of research and development. The design solution integrates physical, social, psychological, medical, and operational requirements to provide an opportunity for a gracious, dignified life-style as an individual ages. Each component of the village is designed to provide, in an unobtrusive way, differing amounts ...

The relevant research is questioning the essence of the existence of an adequate internal circulation to human dimensions. The research was based on the method of anthropometric assessment of internal circulation de Barros (2009), which was applied in three different sizes of apartments in the city of Caruaru-PE. These apartments were evaluated through the floor plans and furniture layouts, sug...

in this research 220 rhizobial bacteria were isolated from two lentil dryland farming flat plains of moghan and koohin. they were then tested in vivo as well as in vitro to make assurance of 184 purified strains of rhizobium leguminosarum biovar vicial (lentil). btb +yma culture media with different levels of salinity through nacl (10, 20,30,40,50ds/m) application were used in salinity toleranc...

The design and construction of non-flat interactive surfaces is an emerging field of research. In this paper, we propose a design space for such displays in order to support structured discussions about differences and design possibilities within this area. Our design space is spanned by basic dimensions of shaped display surfaces, such as size, form and texture. As a starting point, we classif...

Environmental (topography, climate) features have an important influence on plant diversity and richness of Iran. Topography is from –28m which is close to Caspian Sea to 5678m which is located on the Alborz Mountain. Two mountains (Alborz and Zagrosss) prevent moist air moving to the centre of Iran. On the basis of environmental factors, four ecological zones with specific plant richness from ...

The article processing charge (APC) is currently the primary method of funding professionally published Open Access peer reviewed journals. The pricing principles of 77 OA publishers publishing over 1000 journals using APCs were studied and classified. The most commonly used pricing method is a single fixed fee, which can either be the same for all of a publisher’s journals or individually dete...
