The efficient and rapid production of a high-quality, pure beam of highly charged ions is at the heart of any radioactive ion beam facility. Whether an electron cyclotron resonance (ECR) ion source or an electron beam ion source (EBIS) is used to produce these highly charged ions, their operating characteristics will set the boundaries on the range of experiments which can be performed. In addi...

Avian metapneumovirus (aMPV) is an important poultry pathogen causing an acute highly contagious upper respiratory tract infection in chickens leading to swollen head syndrome. The disease can cause significant economic losses in turkey and chicken flocks, particularly when exacerbated by secondary pathogens. The purpose of this study was to determine the prevalence of avian metapneumovirus ant...

The objectives of this study were to 1) evaluate the genetic diversity of Navajo-Churro sheep using pedigree information; 2) examine the distribution of the Navajo-Churro population; and 3) evaluate the effect of breeder dynamics on genetic conservation of the breed. Pedigree data and breeder information (city and state) were obtained from the Navajo-Churro Sheep Breed Association. Inbreeding c...

The efficient and rapid production of a high-quality, pure beam of highly charged ions is at the heart of any radioactive ion beam facility. An ECR charge breeder, as part of the Californium Rare Ion Breeder Upgrade (CARIBU) program at Argonne National Laboratory, was developed to fulfil this role. The charge breeding efficiency and high charge state production of the source are at the forefron...

In this study, seroprevalence of avian reovirus (ARV) infections in broiler and broiler breeder chicken farms in Aydin, İzmir and Manisa provinces were investigated. Serum samples (n = 631) collected from 8 broiler breeder and 18 broiler flocks were tested for ARV antibodies using a commercially available ARV Enzyme Linked Immunosorbent Assay (ELISA) kit. The sampled flocks were not vaccinated ...

Crop management can be defined as the set of agricultural operations that produce the crop. Soil and water science experts, plant pathologists, entomologists, agricultural scientists, and breeders all contribute to these operations. Soil and water conservation are also important factors in crop management. It is important that reliable methods of crop management be transferred to growers in an ...

Chronic Respiratory Disease (CRD) is caused by Mycoplasmas gallisepticum (MG) and is prevailing in layer, broiler and breeder poultry flocks. The infected birds showed sneezing, rales, coughing and exudates from nostrils and eyes. Mycoplasma species were recovered 27.3% overall, 39.3 per cent of the tracheal swabs, 15.9 per cent of tracheal tissues, 27.4 per cent of lung tissues and 25 per cent...
