In order to estimate the mean of maternal antibody in calves against BHV-1 (Bovine Herpes virus type 1), this study was carried out in a population of calves from non-vaccinated dairy cattle at 2 livestock in Qazvin province. One hundred thirteen sera out of 512 were collected from 1-4 months unvaccinated calves. We used Blocking –Percentage of maternal antibodies against BHV-1, which obtained ...

In order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five CMS lines and four restorer lines (tester) were crossed in a line × tester scheme. Hybrids were evaluated in a randomized complete block design with three replications in the Agriculture Research Station, University of Tabriz, in 2009 and 2010 growing seasons. Plant height,...

plasters are produced from a light refractory material, mainly mgo (m.p. 2800ºc), a binder, and a void forming substance for insulating purposes. different oxides from the slag penetrate into these voids and provide low melting-point phases suchasrhodonite (mnsio3) (1290ºc), tephorite (mn2sio4) (1345ºc), merwinite (ca3mgsi2o8) (1575ºc), monticellite (camgsio4) (1490ºc), and enstatite (mgsio3) (...

While attempting to clarify the confusion concerning the conceptualization of "blocking zeros" in state space in the recent literature, some new observations are made on the relationship between pole-zero cancellation and transmission blocking. An important distinction between uncontrollable and unobservable eigenvalue s is pointed out; and it is argued that the description of a Blocking Zero, ...

In a wireless network, blocking probability of connection-oriented traffic depends on the transmission radius of the nodes and the channel assignment scheme. In this work we study these two aspects for simple wireless networks. Specifically, we present blocking probability analysis for a wireless line network with random channel allocation to the incoming calls. Based on the expressions derived...

Microfiltration can clarify pomegranate juice; however, fouling is a limiting phenomenon in the process. In current work ultrasound was applied above and below the membrane surface to reduce fouling after removing temperature effect. A hydrophilic mixed cellulose ester membrane with pore size of 0.45 μm was used in lab scale flat sheet module. Membrane module was placed above and below the ultr...
