the non commuting graph of a non-abelian finite group $g$ is defined as follows: its vertex set is $g-z(g)$ and two distinct vertices $x$ and $y$ are joined by an edge if and only if the commutator of $x$ and $y$ is not the identity. in this paper we prove some new results about this graph. in particular we will give a new proof of theorem 3.24 of [2]. we also prove that if $g_1$, $g_2$, ..., $...
introduction: impaction of third molars can be associated with a number of sequelae, each requiring a different type of treatment. the purpose of this study was to assess the changes in the position of lower third molars following extraction and non-extraction orthodontic treatments. methods: pre- and post-treatment panoramic radiographs of 26 class i malocclusion patients (4 male and 22 female...
let $l$ be a lattice in $zz^n$ of dimension $m$. we prove that there exist integer constants $d$ and $m$ which are basis-independent such that the total degree of any graver element of $l$ is not greater than $m(n-m+1)md$. the case $m=1$ occurs precisely when $l$ is saturated, and in this case the bound is a reformulation of a well-known bound given by several authors. as a corollary, we show t...

lncrnaها (long non-coding rnas)، رونوشتهای غیر کد کنندهی پروتئین با طول بلندتر از 200 نوکلئوتید هستند که از طریق ساختار مولکولی ویژهی خود، با سایر مولکولها در میانکنش بوده و از این طریق بر شماری از فرایندهای مهم سلولی تاثیرگذار هستند. بررسی کارکردهای lncrna در مسیرهای متنوع سلولی، به نحو گسترده مورد مطالعه قرار گرفته است. این مولکولها به شکل طبیعی در انواع سلولها بیان میشوند، اما بیان ک...
