Antihemophilic Factor (Factor VIII)
Annals of Internal Medicine, 1978Antihemophilic factor (Factor VIII) is an agent in normal plasma that corrects the coagulative defect of classic hemophillia. The plasma of hemophiliacs contains normal amounts of a variant of antihemophilic factor deficient in clot-promoting properties. In contrast, von Willebrand's disease is usually associated with a true deficiency of this protein.

It is common practice to refer to a factor premium’s current valuation when assessing its attractiveness—in effect using a single-value-factor model to gauge whether the factor is rich, fairly valued, or cheap. Meanwhile, studies have investigated how some factor premia are exposed to other factor premia in order to characterize their behavior over ...

The Factors in Factoring Behavior
Psychometrika, 1951Twenty years have now elapsed since Professor Thurstone’s ingenuity pulled the factor problem out of its tetrad difference quagmire. Most of us have watched Thurstone’s brain-child grow. One might say that the fledgling was so precocious as to reach maturity during the first ten years of its life.

Journal of the London Mathematical Society, 1998
A noninjective bounded-to-one factor map from an irreducible shift of finite type onto a sofic system can be factored as a composition of other such maps in only finitely many ways (up to isomorphism). This generalizes to factor maps from systems with canonical coordinates to finitely presented dynamical systems.

ACM SIGCHI Bulletin, 1986
The Status of the HFS HCI Standards Committee is reported on in a separate article by Paul Reed of AT&T Bell Laboratories, the vice-chair of that committee. It describes the background, status and approach being followed by that committee in its attempt to develop meaningful standards for user interfaces and the development of user interfaces ...

Factor Prices, Factor Proportions, and Regional Factor Endowments
Journal of Political Economy, 1970in two-digit manufacturing industries. These tests were based on the theoretical proposition that the South, being relatively labor-abundant by comparison with the non-South, should possess a comparative advantage in producing relatively labor-intensive commodities.

CRC Critical Reviews in Clinical Laboratory Sciences, 1980
It has been more than 30 years since Dr. H. S. Lawrence first reported that it was possible to transfer delayed-type hypersensitivity from sensitized donors to unsensitized recipients with lysates of blood leukocytes. During recent years, research from several laboratories has demonstrated that this effect is immunologically specific.

[4] Factor XII: Hageman factor
1993Publisher Summary This chapter discusses the factor XII that is the Hageman factor. The functional activity of factor XII or factor XIIa can be determined via the correction of the abnormal clotting time of human factor XII-deficient plasma by comparing the times obtained through the addition of pooled normal plasma (PNP).

[7] Factor VIII and factor VIIIa
1993Publisher Summary This chapter focuses on the role of factor VIII and factor VIIIa present in blood. The factor VIIIa apparently alters the active site structure of factor IXa to make it recognize the rate-limiting transition state for factor X activation, because its dominant kinetic effect is to increase the kcat.
