Virulence Properties of GI-23 Infectious Bronchitis Virus Isolated in Poland and Efficacy of Different Vaccination strategies

Molecular Studies on Infectious Bronchitis Virus Isolated in Poland

The comparison of the conventional (aimed at the UTR’3 fragment) and nested RT-PCR (aimed at the N gene fragment) based methods revealed that nested PCR was about 1000 times more sensitive for the detection of infectious bronchitis virus (IBV). Molecular differentiation of 793/B, D274, and Mass IBV types was also achieved in multiplex nested PCR. Eight from nine studied Polish isolates had the ...

investigation of gassing behavior, electric and dielectric properties of different insulating fluids.

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...

Isolation and Identification of Infectious Bronchitis Virus from Commercial Chickens

Emergence of variant avian infectious bronchitis virus in India

Background: Infectious bronchitis virus (IBV) is the etiological agent of an acute and highly contagious disease. Infectious bronchitis (IB) affects chicken of all ages and poses major economic loses to the poultry industry worldwide. The continuous evolution of the spike protein (S1) of IBV is responsible for the prevalence of many serotypes/genotypes around the world. Multipl...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
