در این آزمایش اثر شش روش مختلف تهیه زمین و کاشت روی سبزشدن گندم آبی مورد ارزیابی و مقایسه قرار گرفت . به منظور اجرای این تحقیق از طرح بلوکهای تصادفی با 6 تیمار (روشهای مختلف تهیه زمین و کاشت ) در سه تکرار، مجموعا 18 کرت استفاده گردید. بذر مورد استفاده قرار گرفتند، عبارت بودند از: تعداد بوته های سبز شده در واحد سطح و درصد کل بذر سبز شده، یکنواختی توزیع افقی بذر، عمق قرارگیری بذور در خاک و انحراف...
Upon introducing charge carriers into the copper-oxygen sheets of the enigmatic lamellar cuprates, the ground state evolves from an insulator to a superconductor and eventually to a seemingly conventional metal (a Fermi liquid). Much has remained elusive about the nature of this evolution and about the peculiar metallic state at intermediate hole-carrier concentrations (p). The planar resistivi...
A simple matrix is a (0,1)-matrix with no repeated columns. For a (0,1)-matrix F , we define that a (0,1)-matrix A has F as a configuration if there is a submatrix of A which is a row and column permutation of F (trace is the set system version of a configuration). Let |A| denote the number of columns of A. We define forb(m,F ) = max{|A| : A is m-rowed simple matrix and has no configuration F}....
Radial cardiac T2 mapping with alternating T2 preparation intrinsically introduces motion correction
Combinations of chemical and genetic approaches were used to study the function of divalent metal ions in cleavage of RNA by the ribozyme RNase P RNA. We show that different divalent metal ions have differential effects on cleavage site recognition and rescue of cleavage activity by mixing divalent metal ions that do not promote cleavage by themselves. We conclude that efficient and correct cle...

the hotelling's control chart, is the most widely used multivariate procedure for monitoring two or more related quality characteristics, but it’s power lacks the desired performance in detecting small to moderate shifts. recently, the variable sampling intervals (vsi) control scheme in which the length of successive sampling intervals is determined upon the preceding values has been pro...
