years. Books and journals have had almost no rivals as vehicles of scientific progress and practical instruction. From Darwin’s On the Origin of Species to Sir William Osler’s The Principles and Practice of Medicine and the peer-reviewed periodical, this mode of knowledge dissemination has served us remarkably well. But the tradition of publication requires continuing support, and the next gene...

microorganisms are important components of soil. some soil filamentous fungi such aspenicilium produce many bioactive small molecules, or secondary metabolites, that range frombeneficial bioactive compounds to harmful toxins. in this study, the metabolites of threepenicillium species (p. goditanum, p. moldavicum and p. corylophilum) were extracted byadding ethyl acetate to liquid cultures. the ...

let $g$ be a finite $p$-soluble group‎, ‎and $p$ a sylow $p$-subgroup of $g$‎. ‎it is proved‎ ‎that if all elements of $p$ of order $p$ (or of order ${}leq 4$ for $p=2$) are‎ ‎contained in the $k$-th term of the upper central series of $p$‎, ‎then the $p$-length of‎ ‎$g$ is at most $2m+1$‎, ‎where $m$ is the greatest integer such that‎ ‎$p^m-p^{m-1}leq k$‎, ‎and the exponent of the image of $p$...

for a symmetric group $g:=sym(n)$ and a conjugacy class $mathcal{x}$ of involutions in $g$, it is known that if the class of involutions does not have a unique fixed point, then - with a few small exceptions - given two elements $a,x in mathcal{x}$, either $angbrac{a,x}$ is isomorphic to the dihedral group $d_{8}$, or there is a further element $y in mathcal{x}$ such that $angbrac{a,y} cong ang...

BACKGROUND Considering both diet and energy expenditures possess some influence on weight status, research into dietary determinants of obesity is challenging but essential to rational planning of well-organized interventions to avoid obesity. OBJECTIVES This study aimed to determine whether dietary factors were predictive of overweight and obesity in adolescents in the Iranian population. ...
