India is building a 500 MWe Prototype Fast Breeder Reactor, which is scheduled to be operational by 2010. India has refused to accept international safeguards on this facility, raising concerns that the plutonium produced in its uranium blankets might be used to make nuclear weapons. Based on neutronics calculations for a detailed threedimensional model of the reactor, we estimate that up to 14...

Avian reoviruses (ARVs) are considered as an important cause of several diseases in poultry, particularlyarthritis and tenosynovitis. Tenosynovitis and arthritis, which are among the causes of chronic lameness inbreeder flocks, can result in reduced egg production and culling of breeder hens. In this study, the molecularcharacteristics of ARVs in some broiler breeder flocks were investigated in...

salmonella enteritidis (se) is frequently isolated from poultry and humans. chicken meat and egg are two important sources of se infection for humans. this study was conducted to detect the se infection in iranian poultry farms using serological methods. a number of 8208 serum samples were provided from 171 poultry flocks (pullet, commercial layer, broiler breeder, layer breeder, grandparent br...

avian influenza is an important disease of poultry with the potential to cause major epidemics resulting in significant economic losses. the presence of avian influenza viruses (aiv) in chickens in iran has not been previously reported. an avian influenza outbreak in broiler, layer and breeder farms occurred during a very hot summer in july 1998. three aiv isolates designated as 101, 102 and 10...

Present study was carried out on some reported repeat breeder individuals (n=08) of nondescript cows at Para-veterinary hospital, University of veterinary and Animal Sciences, Ravi Campus, Pattoki. Nondescript cows has major share, which is approximately 70% in cattle farming in Pakistan. Chromosomal preparations were made using blood culture from animals under study. About 50 metaphase spreads...

The current study described the isolation and molecular detection of Mycoplasma gallisepticum (Mg) and Mycoplasma synoviae from tracheal swabs of diseased birds showing signs of respiratory distress in selected commercial (layer and broiler) farms and from yolk and an open air of pens of vaccinated breeder flocks in Sudan. A number of 45 Mycoplasma isolates were recovered from chickens in Khart...

Abstract The SPIRAL1 charge breeder is now under operation. Radioactive beam has already been delivered [1] to physicists for performing experiments. Although breeding efficiencies demonstrated high performances stable ion beams, regarding radioactive beams were found be lower than expected in the first experiment. optics, prior injection of 1+ ions into breeder, prime importance [2] reaching s...

Background: The immune response of aged broiler breeder hens is influenced by many factors including obesity and aged lymphatic organs, but may improve by increasing the bioavailability of various nutrients such as zinc (Zn). Dietary supplementation of phytase can improve Zn availability in senescent broiler breeder hens. Aims:</st...
