To investigate the suggestion that von Willebrand factor (vWf) can substitute for fibrinogen in supporting ADP-induced aggregation of human platelets, we studied platelet reactions in two media: (1) a high calcium medium, Tyrode-albumin solution containing calcium ions in the physiological range of 2 mmol/L, and (2) a low calcium medium, modified Tyrode-albumin solution from which calcium salt ...

This paper identifies two notions of substitutes for auction and equilibrium analysis. Weak substitutes, which is the usual price-theory notion, guarantees monotonicity of tâtonnement processes and convergence of clock auctions to a pseudoequilibrium, but only strong substitutes, which treats each unit traded as a distinct good with its own price, guarantees that every pseudo-equilibrium is a W...

The article discusses the possibility of using glycerol as an additive to engine fuel in order reduce tendency combustion knock, and thus increase octane number a given fuel. Experimental tests were carried out on UIT-85 research with variable compression ratio from eight eleven test intensity knock. completely renewable fuel—the blend butanol 25 75%, respectively—was tested. A comparative anal...
