به منظور شناسایی فون کنه های بالا خانواده های raphignatoidea و bdelloidea در میاندوآب، نمونه برداری های مختلفی از خاک و اندام های گیاهان زراعی، باغات و علف های هرز مناطق مختلف طی سال های 1390 – 1389 به عمل آمد. در مجموع تعداد 2500 اسلاید میکروسکوپی تهیه گردید که از این مجموعه تعداد 900 اسلاید مربوط به اندام های هوایی و1600 اسلاید مربوط به فون خاک بود در این مطالعه از خانواده های stigmaeidae (17...
a major concern in the last few years has been the fact that the cultural centers are keeping distance with what they have been established for and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. because the cultural centers, as urban public spaces in the last two decades, have been the subject of ideological dis...
Let $D$ be a digraph, let $p \geq 1$ an integer, and $f: V(D) \to \mathbb{N}_0^p$ vector function with $f=(f_1,f_2,\ldots,f_p)$. We say that has $f$-partition if there is partition $(V_1,V_2,\ldots,V_p)$ of the vertex set such that, for all $i \in [1,p]$, digraph $D_i=D[V_i]$ weakly $f_i$-degenerate, is, in every nonempty subdigraph $D'$ $D_i$ $v$ $\min\{d_{D'}^+(v), d_{D'}^-(v)\} < f_i(v)$. In...
Let f be a nonnegative integer valued function on the vertex set of graph. A graph is strictly f-degenerate if each nonempty subgraph ? has v such that deg?(v)<f(v). In this paper, we define new concept, transversal, which generalizes list coloring, signed DP-coloring, L-forested-coloring, and (f1,f2,…,fs)-partition. cover G H with V(H)=?v?V(G)Xv, where Xv={(v,1),(v,2),…,(v,s)}; edge M=?uv?E(G)...
