هدف: عفونت های ناشی از انتروکوکسی های مقاوم به ونکومایسین در تمامی دنیا در حال افزایش است. مقاومت این باکتری ها به آنتی بیوتیک های گلیکوپپتیدی در ارتباط با ژن های van a, b, c, d, e است که باعث کاهش تأثیر این آنتی بیوتیک ها در دیواره این باکتری ها می شود. منشا این ژن ها تاکنون شناخته نشده است؛ اما مطالعات در سال های اخیر مقاومت انتروکوکوس ها را ناشی از انتقال ژن van b از طریق باکتری های فلور رود...

The first-lactation milk records of 20,850 artificially sired Holstein cows and their darns were analyzed by a sire-by-herd, variance components model to determine if unequal numbers of records in the filled subclasses had any effect on the paternal half-sib correlatiou or the daughter-dam regression. The variance components were estimated with the number per subclass held constant at 1, 2, 3, ...

Direct measurement of soil unsaturated hydraulic conductivity (K(h) or K(θ)) is difficult and time-consuming, and often in many applied models, predicting hydraulic conductivity is carried out according to measurements of soil retention curve and saturated hydraulic conductivity (Ks). However, using KS as a matching point in many procedures may result in over-estimation of unsaturated hydraulic...
