the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...
The title compound, C(34)H(52)N(2)O(7)·CH(4)O, is the methanol solvate of a difunctionalized derivative of the therapeutic agent 18β-glycyrrhetinic acid, a penta-cyclic triterpene. The five six-membered rings of the glycyrrhetinic acid moiety show normal geometries, with four rings in chair conformations and the unsaturated ring in a half-chair conformation. This moiety is substituted by a nitr...
Wave climate is a primary driver of coastal risk, yet how change altering wave not fully understood. Here we identify transitional regions, coastlines with future in the occurrence frequency climate, most regions located south-western and eastern ocean basins. Analysis spatio-temporal changes atmosphere-driven major climates (the easterlies, southerlies westerlies) under 2 emission scenarios fo...
چکیده کنه تارتن دو لکه ای tetranychus urticae koch یکی از چندخوارترین آفات شناخته شده محصولات کشاورزی دنیا به حساب می آید. در این بررسی جمعیت تخم و مراحل فعال این کنه در شرایط آلودگی طبیعی و مصنوعی در برگ های 8 رقم لوبیا در سال 1392 در گلخانه و مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه ارومیه موردمطالعه قرار گرفت. آزمایش به صورت طرح کاملاً تصادفی برای شرایط مزرعه در10 تکرار و برای شرایط گلخانه ای...
Personality scales based on the five-factor model, especially the big-five scale of personality trait adjectives (Wada, 1996), are commonly used in Japan. In this study a short form of the Big-Five Scale was constructed. To avoid changes in the capacity dimension caused by the decrease in the number of items, item selection was conducted after item response theory (IRT) scales were constructed ...
We study how the eightfold-degeneracy in the (θ13, δ) plane observed in γ ∼ 100 β-beams can be reduced by periodically changing the ions in the storage ring. This “ions cocktail” allows to change the neutrino energy, at fixed γ, by choosing ions with different decay energies. We propose to combine the standard He and Ne beams with Li and B ones. These latter two ions have peaked νe → νμ oscilla...
