precise application of the n fertilizer rate is critical to achieve maximum yield. in major regions, empirical methods were used for determining n fertilizer requirement. these methods cannot take into account variation in management and environmental conditions on determining fertilizer requirement. crop simulation models can provide an alternative means of determining the optimum crop n requi...
conclusions more than behalf of the wound isolates were esbl positive, and the presence of blaveb-1 was determined in less than half of these isolates. fortunately, resistance to imipenem and meropenem was low. results the majority of the wound isolates were resistant to augmentin (90%, n = 80) and cefpodoxime (87.6%, n = 78). however, the majority was susceptible to imipenem and meropenem. fif...
La recherche du consentement du patient est un ancien principe, à la fois juridique et éthique, qui se fonde sur le principe du respect de l’intégrité corporelle du patient. Le respect de cette exigence par le corps médical a varié au cours des temps, comme l’illustre l’évolution récente. Le consentement du patient ou de ...
the alternative double bonds and conjugation in the polyene compounds are one of the main properties in these compounds. each carbon-carbon bonds in a polyene compound along the chain has appreciable double-bond character. the p-electrons are therefore not localized but are relatively free to move throughout the entire carbon skeleton as an one-dimensional box. the skeleton be considered as a r...
tio2 nanoparticles were synthesized by modified sol—gel method using pure room temperature ionic liquid(rtil) 2-hydroxyethylammonium formate as a reaction medium. the structure and morphology of tio2nanoparticles were characterized with x-ray powder diffraction (xrd), bet surface analysis and scanningelectron microscopy (sem). tio2 nanoparticles were synthesized in open and closed vessels. the ...

فرض کنید a?c^n×n باشد.ماتریس a^d را معکوس درازین ماتریس a گوییم، هرگاه در سه شرط زیر a^d aa^d=a^d, a^d a=aa^d, a^(k+1) a^d=a^k که در آن k بزرگترین بلوک جردن متناظر با مقدار ویژه صفر ماتریس a می باشد، به نام شاخص a ، که با ind(a) نشان می دهیم، صدق کند. سیدی با تعمیم روش زیر فضای کریلف برای دستگاه های منفرد، یک چارچوب کلی برای محاسبه جواب معکوس درازین دستگاه ax=b ارایه نمود و خواص آن را مورد ب...
background: it has been proposed that oxidative stress plays an important role in male infertility. the aims of this study were to compare seminal plasma levels of 15-f2t-isoprostane (8-iso-pgf2?), malondialdehyde (mda), and total (sum of free and bound) homocysteine (thcy) in normozoospermic vs. asthenozoospermic men, and to examine the relationships between thcy and lipid peroxidation product...
