Molecular incidence, rate

RP can be readily obtained by dividing (R by the rate of molecular incidence F which is obtained from the kinetic theory expression F = P/(iTcMRTy. ... 

The rate of formation of the initiating species and, accordingly, the molecular weight distribution can be controlled by variation of the incident light intensity. 

Primary prevention of venous thrombosis reduces the incidence of and mortality rate from pulmonary emboli. Heparin and warfarin may be used to prevent venous thrombosis. Subcutaneous administration of low-dose unfractionated heparin, low-molecular-weight heparin, or fondaparinux provides effective prophylaxis. Warfarin is also effective but requires laboratory monitoring of the prothrombin time.
