let $m$ be a right module over a ring $r$, $tau_m$ a preradical on $sigma[m]$, and$ninsigma[m]$. in this note we show that if $n_1, n_2in sigma[m]$ are two$tau_m$-lifting modules such that $n_i$ is $n_j$-projective ($i,j=1,2$), then $n=n_1oplusn_2$ is $tau_m$-lifting. we investigate when homomorphic image of a $tau_m$-lifting moduleis $tau_m$-lifting.
in this paper, we present algebroids and crossed modules of algebroids. we also define pullbackcrossed module of algebroids.
the author studies the $bf r$$g$-module $a$ such that $bf r$ is an associative ring, a group $g$ has infinite section $p$-rank (or infinite 0-rank), $c_{g}(a)=1$, and for every proper subgroup $h$ of infinite section $p$-rank (or infinite 0-rank respectively) the quotient module $a/c_{a}(h)$ is a finite $bf r$-module. it is proved that if the group $g$ under consideration is local...
فرض کنید g گروهی با خاصیت موضعا فشرده باشد، بطوریکه همزمان یک فضای موضعا فشرده هاسدروف است که عملگرهای گروهی آن پیوسته باشند. همچنین فرض کنید که یک تابع وزنی تعریف شده بر گروه g باشد (این تعریف در شماره 2.1.11 ذکر شده است ). هدف ما آن است که تمام عملگرهای خطی و کراندار t را مشخص کنیم بطوریکه t: l1( )--->b باشد و در شرط t (f*g) f*t(g) صدق کند، جائیکه b یک فضای باناخ شامل رادون میجرهای تعریف شده ...
in the first chapter we study the necessary background of structure of commutators of operators and show what the commutator of two operators on a separable hilbert space looks like. in the second chapter we study basic property of jb and jb-algebras, jc and jc-algebras. the purpose of this chapter is to describe derivations of reversible jc-algebras in term of derivations of b (h) which are we...
background: yazd waste stabilization pond facilities consist of three stabilization pond systems, module 1, module 2 and module 3 that awsp module 1 has started its operation. the existing facilities have had several problems in their operation. the objectives of this research were to evaluate the performance of stabilization ponds in wastewater treatment of the city of yazd, due to several pro...
مقدمه: مطالعات درباره کیفیت زندگی مرتبط با سلامت دهان کودکان مبتلا به اوتیسم محدود است. هدف این مطالعه بررسی درک والدین از کیفیت زندگی مرتبط با سلامت دهان در کودکان اوتیستیک شهر مشهد در سال 93 بود. روش بررسی : 70 کودک مبتلا به اوتیسم و 70 کودک سالم 12-8 ساله و خانواده هایشان وارد مطالعه شدند. ابزار مطالعه پرسشنامه ی pedsql oral health scale بودکه شامل حیطه های درد دندان، درد لثه، خونریزی از ل...
let r be a commutative ring and m be an r-module. we say that m is fully primary, if every proper submodule of m is primary. in this paper, we state some characterizations of fully primary modules. we also give some characterizations of rings over which every module is fully primary, and of those rings over which there exists a faithful fully primary module. furthermore, we will introduce some ...

In this paper we introduce the notions of G∗L-module and G∗L-module whichare two proper generalizations of δ-lifting modules. We give some characteriza tions and properties of these modules. We show that a G∗L-module decomposesinto a semisimple submodule M1 and a submodule M2 of M such that every non-zero submodule of M2 contains a non-zero δ-cosingular submodule.
