Sloane’s influential On-Line Encyclopedia of Integer Sequences is an indispensable research tool in the service of the mathematical community. The sequence A001611 listing the “Fibonacci numbers + 1” contains a very large number of references and links. The sequence A000071 for the “Fibonacci numbers −1” contains an even larger number. Strangely, resentment seems to prevail between the two sequ...

Training is an intentional act of creating a learning environment, after which people may apply their learning in the work field. It is no more a reactive role in organisational life, but it has become an integral part of business and line managers of the organisation, where it forms a transformational role in decision-making, strategic development, policy formulation and business management. C...

Supermatrix and supertree methods are two strategies advocated for phylogenetic analysis of sequence data from multiple gene loci, especially when some species are missing at some loci. The supermatrix method concatenates sequences from multiple genes into a data supermatrix for phylogenetic analysis, and ignores differences in evolutionary dynamics among the genes. The supertree method analyze...

In order to study relative PCF-definability of boolean functions, we associate a hypergraph Hf to any boolean function f (following [2, 4]). We introduce the notion of timed hypergraph morphism and show that it is: – Sound: if there exists a timed morphism from Hf to Hg then f is PCF-definable relatively to g. – Complete for subsequential functions: if f is PCF-definable relatively to g, and g ...

let c be a field of subsets of a set i. also, let     1 i i be a non-decreasing positivesequence of real numbers such that 1, 1 0 1   i  and    11 i i . in this paper we prove thatbv of all the games of -bounded variation on c is a non-separable and norm dual banach space of thespace of simple games on c . we use this fact to establish the existence of a linear mapping t from...

a simple new closed form of the green function for axisymmetric magnetostatic problemsis found analytically in cylindrical coordinates. the result is verified by applying several examples.

the aim of this study was to investigate the relationship between family function and marital satisfaction with marital disaffection of married couples (teachers)  in behshahr.   the research method is descriptive and co-relational. the study sample group consisted of 250 married teachers in 2016, of which 150 of them were selected according to morgan random sampling. the research instruments w...

introduction: metabolic syndrome (mets) and impaired lung functions have been associated with an increased risk for coronary heart disease. the aim of this study was to investigate the pulmonary functions in patients with mets. methods: this cross-sectional study included 200 subjects with mets in the study group and 100 subjects without mets in the control group. participants were examined at ...

although there exist advanced models which predict beach profile for natural beaches, the behavior of the beaches in front of seawalls still suffers from the lack of appropriate theoretical models and sufficient measured data. in this paper, following the results obtained from the measurements, a beach profile evolution model is developed, using the measured probability distribution of the near...

background: sickle-cell anemia is characterized by defective hemoglobin synthesis with production of sickle hemoglobin. sickle red blood cells become deformed and rigid with difficulty to pass through narrow capillaries and frequent clotting and thrombosis leading to repetitive vascular occlusions and progressive organ damage. we conducted this work to study some adrenal functions using acth st...
