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.

Applied Categorical Structures, 2001
Let \(\mathcal K\) be a category. We say that a functor \(F:\mathcal K \to\mathcal L\) preserves a class \(\mathcal E\) of \(\mathcal K\)-epimorphisms (or a class \( \mathcal M\) of \(\mathcal K\)-monomorphisms) if \(F(\mathcal E)\) (or \(F(\mathcal M)\)) is a subclass of \(\mathcal L\)-epimorphisms (or \(\mathcal L\)-monomorphisms).

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.

Factors and factors of personality.
Psychological Bulletin, 1975An effort was made to account for the diverse sets of factors of personality found by the analysis of questionnaire items as reported by different investigators and to see what common ground there might be. Divergencies were attributed to certain insufficiencies in factor analysis and to the fundamental views of analysts with regard to emphasis upon ...

FACTOR INTERACTION IN NONLINEAR FACTOR ANALYSIS
British Journal of Mathematical and Statistical Psychology, 1967Factor interaction models are defined as those cases in nonlinear factor analysis in which the specification equation contains products of two or more latent variables or functions of latent variables. A complete algebraic treatment is given for the case of a product of two latent variables, and certain more general cases are briefly outlined.

On the Stability of Factorization Factors
1987The present chapter is devoted to the study of the behaviour of the factorization factors under small perturbations of the matrix function G. Here we encounter another qualitative difference between the matrix case (n > 1) and the scalar one (n = 1). It appears that the partial indices of a matrix function and the factorization factors G± are unstable,

Ovum factor and early pregnancy factor.
Current topics in developmental biology, 1987This chapter describes experimental evidences, which shows that production of early pregnancy factor (EPF) is initiated by fertilization and that its presence in serum monitors the viability of the conceptus for at least the first half of gestation. Furthermore, EPF is necessary for the continued survival of the conceptus.
