We consider overlapping Additive Schwarz Method(ASM) with Robin conditions as the transmission conditions(interior boundary conditions). The main difficulty left in this field is how to select the parameters for Robin conditions – these parameters have strong effect on the convergence rate of ASM. In this paper, we proposed the parameters for linear elliptic problems which seemed to be near opt...

In this paper, we propose a sufficient condition for a solution to be optimal for a 2-additive Choquet integral in the context of multiobjective combinatorial optimization problems. A 2-additive Choquet optimal solution is a solution that optimizes at least one set of parameters of the 2-additive Choquet integral. We also present a method to generate 2-additive Choquet optimal solutions of mult...

It is now quite proper to speak of an "active site" or "center" in (or on) a number of hydrolytic enzymes, chymotrypsin in particular. Such sites have been clearly demonstrated and in some cases they have even been investigated in detail. We are almost persuaded that they are the actual loci of enzyme activity in nature. Whatever we think of them, we do know that they are "some peculiar arrange...

This study is focused on fabrication and characterization of mixed matrix poly ether sulfone based nanofiltration membrane by phase inversion method. The effect of different amounts of Ilmenite (FeTiO3) particles as inorganic filler additive in the casting solution on physic-chemical characteristics of membranes was studied. Scanning electron microscopy, surface analysis, water content, contact...

The creation methodology of pathogenetic compositions of amino acids and their derivatives on the basis of their physiological concentration for practical application in oncology of their regulatory effects discussed.

BACKGROUND Platelets are routinely stored in plasma for 5 days at an average temperature of 22°C. In the present study, the shelf life of random donor platelets was extended by storing for 7 days with and without additive solution at temperatures of 22°C, 18°C, and 16°C. METHODS Random donor platelets were stored in 100% plasma and 20%/80% platelet additive solution. The data were compared us...

Introduction: Platelets are small, anucleated cytoplasmic fragments that play an essential role in blood clotting and wound healing. Platelets are routinely stored in plasma for five days at 220C. Aim: Our objective was to assess platelet morphology and function in random donor platelet stored for seven days in platelet additive solution. Methods: The random donor platelet was prepared by PRP m...
