the quest for power has formed much of the world history especially in 20th and 21st centuries. oil (energy) particularly after industrial revolution has been a tool for conquest and power and has been transformed to a geopolitical issue. from a geopolitical point of view this has been the case for the last two centuries in central asia and caucasus. central asia and caucasus has always been...
a $p$-group $g$ is $p$-central if $g^{p}le z(g)$, and $g$ is $p^{2}$-abelian if $(xy)^{p^{2}}=x^{p^{2}}y^{p^{2}}$ for all $x,yin g$. we prove that for $g$ a finite $p^{2}$-abelian $p$-central $p$-group, excluding certain cases, the order of $g$ divides the order of $text{aut}(g)$.
background : primary central nervous system involvement and central nervous system relapse are poor prognostic events in acute lymphoblastic leukemia. due to severe skeletal and endocrine complications of craniospinal radiotherapy, only cranial radiotherapy is advisable. however only 15% of the cases with central nervous system relapse may remain in remission; a second central nervous system or...
Background and Objectives: Improving nurses’ adherance with nursing standard catheter care is needed to enhance the quality of central venous catheters care. This study aimed to compare the effect of collaborative teaching method and lecture method on nursesing care of Central venous catheters. Materials and Methods: This quasi- experimental pretest-post test design study was conducted...
a $p$-group $g$ is $p$-central if $g^{p}le z(g)$, and $g$ is $p^{2}$-abelian if $(xy)^{p^{2}}=x^{p^{2}}y^{p^{2}}$ for all $x,yin g$. we prove that for $g$ a finite $p^{2}$-abelian $p$-central $p$-group, excluding certain cases, the order of $g$ divides the order of $text{aut}(g)$.
the aim of this study is investigating the effect of teaching “metacognitive strategies” on the way which scientific information retrieval workes by the using of google scholar searching machine on the students of ms in the psycology & education faculty of allameh tabatabayi university in 2007-2008 academic year. the statistical community was the students of ms in psychology & education facult...
let $g$ be a finite $p$-soluble group, and $p$ a sylow $p$-sub-group 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 $p$...
the aim of this study was to investigate the effect of different rhythms of music on some central and peripheral fatigue indices in non-athlete young females. for this purpose, 38 healthy female students were randomly divided into three groups: fast music group or exp1 (n=13, m+sd age: 22+2 years), slow music group or exp2 (n=13, m+sd age: 23+2 years) and control group (n=12,m+sd age: 23+2 year...
Introduction: Precocious pubertyin girls refers to onset of puberty before age 8. The purpose of this study therefore was the study of the effect of aerobic training and the use of GnRH agonists on estradiol serum levelsand Gonadotropins in girls with central precocious puberty. Methods: Twenty-five girls with central precocious puberty (aged 7.44±0.34 years) participated in this stud...
let $gamma$ be a normal subgroup of the full automorphism group $aut(g)$ of a group $g$, and assume that $inn(g)leq gamma$. an endomorphism $sigma$ of $g$ is said to be {it $gamma$-central} if $sigma$ induces the the identity on the factor group $g/c_g(gamma)$. clearly, if $gamma=inn(g)$, then a $gamma$-central endomorphism is a {it central} endomorphism. in this article the conditi...
