To locate the genes controlling adaptability in bread wheat using AMMI (additive main effect and multiplicative interaction) model, twenty-one substitution lines derived from the parents Chinese Spring (recipient) and Chayan (donor) were used in a randomized complete block design with three replications in three different environments in the Agricultural College of Razi University, Kermanshah, ...
چکیده روغن اسانسی اندام های هوایی دو گونه گیاهی ایران از خانواده نعنائیان (nepeta persica، nepeta asterotricha) به دو روش تقطیر با آب و head space به دست آمد و ترکیبات موجود در آن ها به وسیله کروماتوگرافی گازی همراه با طیف سنجی جرمی جداسازی و شناسایی گردید. در روغن اسانسی حاصل از اندام هوایی n. persica، 18 ترکیب از 22/92% کل اسانس شناسایی شد و محصولات عمده (5/16%) 4a?, 7?, 7a? nepetalactone، ...

This Article contains an error in Figure 4A where the graphs were labelled incorrectly. The correct Figure 4A appears below as Figure 1.
oEE We study the problem of quantization for distributed parameter estimation in large scale sensor networks. Assuming a Maximum Likelihood estimator at the fusion center, we show that the Fisher Information is maximized by a scoreD 2 function quantizer. This provides a tight bound on best possible MSE for any unbiased estimator. Furthermore, we Y. show that for a general convex metric, the opt...
Location of the active site and proposed catalytic mechanism of pterin-4a-carbinolamine dehydratase.
Based on the recently solved three-dimensional structure of pterin-4a-carbinolamine dehydratase from rat/human liver the involvement of the proposed active-site residues Glu57, Asp60, His61, His62, Tyr69, His79, Arg87 and Asp88 was examined by site-directed mutagenesis. Most of the mutants showed reduced activity, and only the Glu57-->Ala mutant and the His61-->Ala, His62-->Ala double mutant we...
The oligomeric structure of bacteriophage T7 gene 4 helicase/primase proteins was investigated using protein cross-linking and high pressure gel-filtration chromatography. Studies were carried out with both 4A' and 4B proteins. 4A' is a M64L mutant of 4A which has similar helicase and primase activities as the wild-type mixture of 4A and 4B proteins (Patel, S. S., Rosenberg, A. H., Studier, F. ...
در پودر های شوینده معمولا جهت نرم سازی آب و کف کردن پودر به عنوان سازنده، علاوه از stpp از زئولیت a نیز استفاده می شود. بنابراین در این پروژه روشهای سنتز نانو کریستال های زئولیت a و روشهای خصوصیت سنجی آنها مورد مطالعه قرار گرفته است. همچنین کارآئی های این نوع زئولیت به عنوان سازنده در پودر شوینده لباس شوئی مورد بررسی قرار گرفت. که در نتیجه ی آن کارآئی خوبی برای آنها نسبت به زئولیت معمولی دریافت...
Mass analysis with islands of stability has been investigated with three linear quadrupole mass filters: two with 4% added hexapole fields constructed with equal diameter (quadrupole 4A) and unequal diameter (quadrupole 4B) rods, and a conventional round-rod quadrupole that has apparently been slightly damaged. Islands are formed by applying auxiliary quadrupole excitation. With the Mathieu par...
