this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...

hansen et. al., using the autographix software package, conjectured that the szeged index $sz(g)$ and the wiener index $w(g)$ of a connected bipartite graph $g$ with $n geq 4$ vertices and $m geq n$ edges, obeys the relation $sz(g)-w(g) geq 4n-8$. moreover, this bound would be the best possible. this paper offers a proof to this conjecture.

این پایان نامه که به تبیین و تشریح تعمیمی از مدول های کوهمولوژی موضعی نسبت به ایده آل های (i,j)می پردازد. فرض کنیمr یک حلقه جابجایی و نوتری، iوjدو ایده آل از rباشند. فرض کنیمr موضعی با ایده آل ماکسیمالm باشد. نشان می دهیم : (i) برای هر r-مدول متناهی مولد m تساوی زیر برقرار است، inf lbrace i vert h^{i} _{i,j} (m) mbox{نیست آرتینی} brace =inf lbrace depth m_{p} ver...
فرض کنیم $rhspace{1mm}$ حلقه ای جابجایی، یکدار، نوتری و $i$ و $j$ ایده آل هایی از آن باشند. هم چنین فرض کنیم $m$ یک $r$-مدول و $t$ عدد صحیح نامنفی باشد. ابتدا ثابت کرده ایم که اگر $mathrm{ext}^t_r(r/i,m)$ یک $r$-مدول متناهی و ${h}^t_i(m)$ یک $r$-مدول مینی ماکس و برای هر $i<t$، ${h}^i_i(m)$ مدول های $i$-هم متناهی باشند، آنگاه ${h}^t_i(m)$ یک $r$-مدول $i$-هم مت...
This study was conducted to evaluate the effects of nitrogen fertilizer and plant density on the capacity of photosynthesis (leaf area index, the number of leaves and the chlorophyll contents), yield components and yield of maize. The experiment laid out as split plot based on a randomized complete block design with three replications in 2011 summer planting at research station of Kurdistan Uni...
Ca2+ entry through store-operated Ca2+release-activated Ca2+ (CRAC) channels is essential for T-cell activation and proliferation. Recently, it has been shown that 3,5-bistrifluoromethyl pyrazole (BTP) derivatives are specific inhibitors of Ca2+-dependent transcriptional activity in T-cells (Trevillyan, J. M., Chiou, X. G., Chen, Y. W., Ballaron, S. J., Sheets, M. P., Smith, M. L., Wiedeman, P....
