شناسایی و گزینش ژنوتیپ های برتر اولین گام در برنامه اصلاحی درخت گردو است. به منظور شناسایی ژنوتیپ های برتر استان لرستان طی سال های 1387 تا 1388 بیش از 35 هزار ژنوتیپ بذری مورد ارزیابی قرار گرفت. 288 درخت گردو از توده شناسایی شده انتخاب و 29 صفت ظاهری براساس توصیف نامه ipgri مورد ارزیابی قرار گرفت. در نهایت 54 ژنوتیپ امیدبخش با ارزیابی 10 صفت مهم ظاهری در پنج گروه مختلف دسته بندی شدند. براساس نت...
There is a need for the communities to develop their health financing system, most especially those that were not covered by the National Health Insurance Scheme (NHIS). This will give the people an opportunity to finance their medical care which in turn would alleviate financial burden at the point of treatment. Therefore, this study is aimed to determine the level of awareness for Community B...
behavioral Spectrum in hard power include commitment, force and command and behaviors spectrum in soft power include attraction, cooperation and definition of instructions( Nye, psychological operation quarterly,2007 winter,n18,pages 129-152). Todays, soft and cultural power in international field has found especial important and priorities. As all countries of important and influence in inter...
Let E = ∪j=1[a2j−1, a2j ], a1 < a2 < ... < a2l, l ≥ 2 and set ω(∞) = (ω1(∞), ..., ωl−1(∞)), where ωj(∞) is the harmonic measure of [a2j−1, a2j ] at infinity. Let μ be a measure which is on E absolutely continuous and satisfies Szegő’s-condition and has at most a finite number of point measures outside E, and denote by (Pn) and (Qn) the orthonormal polynomials and their associated Weyl solutions...
or show that none exists. The first practical algorithm for linear programming was the simplex method, introduced by Dantzig in 1947 [7]; while efficient in practice, for most known pivoting rules the method has an exponential-time worst case complexity. Several other algorithms were developed over the subsequent decades, such as the relaxation method by Agmon [2] and Motzikin and Shoenberg [13...
OBJECTIVE In recent years, a promising tool has been introduced which allows the co-registration of electroencephalographic (EEG) activity during brain transcranial magnetic stimulation (TMS). The aims of the present study are to identify eventual stimulus-related artefacts, and to confirm and extend previous EEG/TMS findings about the possible networks generating EEG responses evoked by TMS. ...
The 52nd Directing Council of the Pan American Health Organization (PAHO), in response to a call for action of the Minister of Health of El Salvador, recognized chronic kidney disease from nontraditional causes (CKDnT) affecting agricultural communities in Central America as a serious public health problem that requires urgent, effective, and concerted multisectoral action [1]. Most Central Ame...
We show in a simple way that for any k,m ∈ N, there exists a tree T such that the number of independent sets of T is congruent to k modulo m. This resolves a conjecture of Wagner (Almost all trees have an even number of independent sets, Electron. J. Combin. 16 (2009), # R93). 1 The number of independent sets in a tree A set of vertices in a graph G is called independent if the set induces no e...
This article provides an Omega-result for the remainder term in Weyl’s law for the spectral counting function of certain rational (2l+ 1)-dimensional Heisenberg manifolds. Introduction. For M a closed n -dimensional Riemannian manifold with a metric g and Laplace-Beltrami operator ∆, let N(t) denote the spectral counting function N(t) := ∑ λ eigenvalue of ∆ λ≤t d(λ) where d(λ) is the dimension ...
Four neurotoxins that activate the action potential Na+ ionophore of electrically excitable neuroblastoma cells interact with two distinct classes of sites, one specific for the alkaloids veratridine, batrachotoxin, and aconitine, and the second specific for scorpion toxin. Positive heterotropic cooperativity is observed between toxins bound at these two classes of sites. Tetrodotoxin is a nonc...
