conclusions abnormal eating attitude was notable among physical education students in tabriz, iran. it seems that some anthropometric indices such as bmi and central obesity indices were related to the increase of disordered eating attitude. background abnormal eating behavior, unhealthy weight control methods, and eating disordered symptoms have risen among college students. objectives the aim...

Let C(n, p) be the set of p-compositions of an integer n, i.e., the set of ptuples α = (α1, . . . , αp) of nonnegative integers such that α1+ · · ·+αp = n, and x = (x1, . . . , xp) a vector of indeterminates. For α and β two p-compositions of n, define (x + α) = (x1 + α1) β1 · · · (xp + αp) βp . In this paper we prove an explicit formula for the determinant detα,β∈C(n,p)((x + α) ). In the case ...

A (1, k)-composition of a positive integer n consists of an ordered sequence of the integers 1 and k whose sum is n. A palindromic (1, k)-composition is one for which the sequence is the same from left to right as from right to left. We give recursive equations and generating functions for the total number of such compositions and palindromes, and for the number of 1’s, k’s, “+”signs and summan...

Web services are widely used thanks to their features of universal interoperability between software assets, platform independent and loose-coupled. Web services composition is one of the most challenging topics in service computing area. In this paper, an approach based on High Level Petri-Net model as dynamic configuration schema of web services composition is proposed to achieve self adaptat...

BACKGROUND Space-for-time substitution-that is, the assumption that spatial variations of a system can explain and predict the effect of temporal variations-is widely used in ecology. However, it is questionable whether it can validly be used to explain changes in biodiversity over time in response to land-cover changes. HYPOTHESIS Here, we hypothesize that different temporal vs spatial traje...

objective: nowadays the value of bioelectrical impedance analysis (bia) in the estimation of body adiposity both on a clinical basis in the individual and epidemiologically in large populations is of great interest. the current study determine accuracy of bia compared with body mass index (bmi) measurement for estimating body composition in a group of normal weight employee women with a sedenta...

Let c(n) be the number of compositions (ordered partitions) of the integer n whose Ferrers diagram fits inside a k× l rectangle. The purpose of this note is to give a simple, algebraic proof of a conjecture of Vatter that the sequence c(0), c(1), . . . , c(kl) is unimodal. The problem of giving a combinatorial proof of this fact is discussed, but is still open.

expansive behavior is usually observed in soils, which contain fractions of clay minerals in their composition. water absorption of clay particles and change of natural water content of soil up to plastic limit and down to shrinkage limit will cause significant volume change in expansive soils and will result in severe damages to the structures, buildings and foundations. swelling potential is ...

BACKGROUND The phenolic composition of grapes is key when making decisions about harvest date and ensuring the quality of grapes. The present study aimed to investigate the relationship between the detailed phenolic composition of grapes and the agronomic parameters and hyperspectral indices, with the latter being measured via field radiometry techniques. RESULTS Good correlations were found ...
