Inactive factor

Inactive factors 1. Mechanism of action Heparin acts indirectly by binding to antithrombin III to cause a rapid anticoagulant effect. Maximal anticoagulation occurs within minutes after intravenous heparin injection (unlike vitamin K antagonist anticoagulants, such as war-...

Most methods of analysis assume that the objective is to identify a few active factors, those with nonnegligible main effects, to separate them from the inactive factors, those with negligible main effects. 

We now apply Voss method to the data from the plasma etching experiment to construct individual 95% confidence intervals for each effect using u = 8. The pooling of 8 sums of squares into the denominator (3) provides a reasonably robust procedure without undue loss of power. One could, of course, pool more than 8 sums of squares into the denominator, as one would usually anticipate greater effect sparsity—more than 8 negligible effects—in a screening experiment. Still, 8 provides a reasonable trade-off between power and robustness. Also, for simultaneous confidence intervals, Dean and Voss (1999) provided critical values for this choice because, in a single replicate 24 factorial experiment, an inactive factor is involved in 8 inactive main effects and interactions which could then be used to provide the denominator (3) in Voss method. 

Coumarin derivatives decrease the blood concentrations of inactive factors II, VII, IX and X, by inhibiting their synthesis in the liver. 

Thrombin cannot be allowed to circulate freely in the blood, but must be produced rapidly when clotting is initiated. Thrombin is derived from its inactive precursor, prothrombin, in a cascade of reactions in which a sequence of inactive factors is activated each factor activates the next by proteolytic cleavage. The whole process is initiated by exposure of blood to an abnormal surface, such as collagen, which initially triggers the aggregation of platelets. 

Diphtheria toxin Catalyzes a reaction between NAD and EF2 to yield an inactive factor. Inhibits translocation. 

The results of this study may be used to set improved (but not optimum) conditions for the process. The three inactive factors may be set according to our convenience - for example, maximum load, maximum extrusion rate and minimum granulation time in order to shorten the time of the process. The percentage binder is fixed at its maximum value of 1%. The spheronization speed and spheronization time may be set to their optimum (minimum) values, but we might well consider that these parameters, along with the water content would repay further study, perhaps changing the limits of the experimental domain and investigating possible interactions between variables.
