The surface (SU) envelope glycoproteins of feline leukemia virus subgroup B (FeLV-B) and amphotropic murine leukemia virus (A-MLV) are highly related, even in the variable regions VRA and VRB that have been shown to be required for receptor recognition. However, FeLV-B and A-MLV use different sodium-dependent phosphate symporters, Pit1 and Pit2, respectively, as receptors for infection. Pit1 an...

Abstract Vanadium redox flow battery (VRB) has attracted enormous attention as a large-scale energy storage system owing to its long life, stable capacity and high safety. The electrode porosity plays crucial role in the performance of VRB. This work reports effect on electrocatalytic activity charge transfer VRB using spent tea derived porous carbon material. microstructure is systematically m...

A violência relacionada à bruxaria (VRB), particularmente direcionada a mulheres e crianças, tem se tornado uma fonte de crescente preocupação para organizações direitos humanos neste século. Contudo, aqueles que fogem VRB, tal não refletido no reconhecimento da condição refugiado. Esta pesquisa examina como alegações VRB foram abordadas em todas as decisões refúgio disponíveis inglês, oriundas...

Climate change has become a global issue, not only because it affects the intensity and frequency of rainfall but also impacts economic development regions whose economies heavily rely on rainfall, such as West African region. Hence, need for this study, which is aimed at understanding how may in future over Sahel, Savannah, coastal zones Volta River Basin (VRB). The trends changes between 2021...

_____________ _ The increasing use of membrane oxygenators and collapsable venous reservoir bags (VRB) imposes a concern not associated with bubble oxygenators: Venous line air. Since no defoamer is present, a VRB must rely on flow characteristics or a barrier to remove air from the venous return. The purpose of this study is to determine the air removal efficiency of seven commercially availab...

In this article, an electrolyte flow rate control approach is developed for all-vanadium redox battery (VRB) system based on the linear parameter varying (LPV) framework. The regulated to provide a trade-off between stack voltage efficiency and pumping energy losses, so as achieve efficient operation. nonlinear process model embedded in state–space description set of state feedback controllers ...

The proton exchange membrane (PEM) fuel cell is a green energy producer which converts chemical energy to electricity in high yield. Alternatively, the vanadium redox flow battery (VRB) is one of the best rechargeable batteries because of its capability to average loads and output power sources. These two systems are modeled by Nernst equation and electrochemical rules. An effective energy gene...
