from Oh43 (Darrah and Zuber, 1986). Smith (1988) reported that a small number of lines, including B73, Tropical maize (Zea mays L.) represents the most diverse readily A632, Mo17, and Oh43, were the major contributors to available source of germplasm to broaden the limited genetic base of commercial U.S. maize hybrids. Subsequently, Smith et temperate maize in the USA. One objective of this stu...

nelson's syndrome is usually characterized by hyperpigmentation, elevated level of acth, and pituitary adenoma, which is frequently available as macroadenoma. it is usually occurred in the patients suffering from cushing's syndrome. growth of tumor has been revealed in 10-30% of the patients following adrenalectomy. tumors are often benign in nelson's syndrome. the selected treat...

A finite family B of balls with respect to an arbitrary norm inRd (d ≥ 2) is called a non-separable family if there is no hyperplane disjoint from ⋃ B that strictly separates some elements of B from all the other elements of B in Rd . In this paper we prove that if B is a non-separable family of balls of radii r1, r2, . . . , rn (n ≥ 2) with respect to an arbitrary norm in Rd (d ≥ 2), then B ca...

Nelson algebras arise naturally in algebraic logic as the algebraic models of Nelson’s constructive logic with strong negation. This note gives two characterisations of the variety of Nelson algebras up to term equivalence, together with a characterisation of the finite Nelson algebras up to polynomial equivalence. The results answer a question of Blok and Pigozzi and clarify some earlier work ...

Jerry Goodman introduced me to response modes in the spring of 1969, while I was a graduate student in clinical psychology at UCLA and he was my clinical supervisor. He used the modes to describe my alternatives as I tried to listen and respond helpfully to my psychotherapy clients. He distinguished six categories of "help intended" communication: (1) Question, for gathering information, (2) Ad...

Two mathematical models with seven and six parameters have been created for use as methods for identification of the optimum mobile phase in chromatographic separations. A series of chromatographic response functions were proposed and implemented in order to assess and validate the models. The assessment was performed on a set of androstane isomers. Pearson, Spearman, Kendall tau-a,b,c and Good...
