Egg drop syndrome (EDS) is caused by a hemagglutinating adenovirus which has become a major cause of lost egg production and sever economic losses in breeder and layer chicken flocks throughout the world. A PCR assay was optimized for detection of EDS virus in inoculated allantoic fluids (AFs) of duck and chicken emberyonated eggs. Two strains of EDS viruses were propagated in allantoic cavit...

India has long pursued a fast breeder program, motivated in part by the availability of only poor quality uranium resources within the country. But progress so far has been disappointing, with only one test reactor having been constructed and having a chequered operating history. The larger Prototype Fast Breeder Reactor that is being constructed has a design that compromises safety and will pr...

In this paper, the discrete element method (DEM) approach has been applied to study mechanical behaviors of ceramic breeder ebble beds. Directly simulating the contact state of each individual particle by the physically based interaction laws, the DEM umerical program is capable of predicting the mechanical behaviors of non-standard packing structures. The program can also rovide the data to tr...

Sera samples from 89 dairy cows with repeat breeder and 94 healthy pregnant dairy cows (controls) from Elazig province of eastern Turkey were tested for presence of Neospora caninum antibodies by use of a competitive enzyme linked immunosorbent assay (cELISA). Fifteen out of 183 cows tested (8.19%) were found to be seropositive to N. caninum antibody. Overall, seroprevalence of N. caninum was s...

In recent years, the Philippines have seen a robust swine industry, with record high farm gate price per kg of live hogs. This augurs well for swine raisers considering the eradication of Foot and Mouth Disease as well as the absence of major disease outbreaks. The improved housing which resulted in the proliferation of tunnel ventilated houses was one of the contributory factors for such a phe...

Italy has experienced recurrent incursions of H5N2 avian influenza (AI) viruses in different geographical areas and varying sectors of the domestic poultry industry. Considering outbreak heterogeneity rather than treating all outbreaks of low pathogenicity AI (LPAI) viruses equally is important given their interactions with the environment and potential to spread, evolve and increase pathogenic...

The common carotid arteries of normotensive non-arteriosclerotic Sprague-Dawley (S-D) rats, mildly hypertensive but arteriosclerotic breeder S-D rats, severely hypertensive but non-arteriosclerotic virgin spontaneously hypertensive rats (SHR), and severely hypertensive breeder SHR were ligated to induce injury. Three weeks post-ligation, the animals were killed and histopathological sections of...

A testing strategy and corresponding test plan have been presented for the two proposed US candidate breeder blankets: (1) a helium-cooled solid breeder concept with ferritic steel structure and Be neutron multiplier, but without a fully independent TBM and (2) a dual-coolant helium-cooled ferritic steel structure with self-cooled LiPb breeding zone that uses a flow channel insert as MHD and th...
