Sera of 30 Belgian and 10 Northern French chicken farms were tested by a Chlamydia (C.) psittaci major outer membrane protein (MOMP) based ELISA. Ninety-six percent, 93% and 90% of the Belgian broilers, broiler breeders and layers were seropositive. Ninety-one percent of the French broilers were seropositive. In addition, tissues of 5 Belgian and 5 French broiler farms were examined at slaughte...

Server farms are popular architectures for computing infrastructures such as supercomputing centers, data centers and web server farms. As server farms become larger and their workloads more complex, designing efficient policies for managing the resources in server farms via trial-and-error becomes intractable. It is hard to predict the exact effect of various parameters on performance. Stochas...

in this study, farm level technical efficiency (te) and its determinants were investigated. a stochastic cobb-douglas (cd) production frontier was used to provide estimates of input-oriented te for a sample of 100 rain fed farms in two palestinian governorates. empirical findings showed that the estimated te of the farms in the pooled sample ranged from 35.7 to 95.6%, with a mean value of 72.2%...

  Background : Since milk is considered as one of the most common foods in human life, this research aimed to evaluate the quality of milk produced in traditional and industrial dairy farms of Yazd province in 2007.   Materials and Methods : In this descriptive study, six farms were selected in the cities Sadoogh, Yazd and Mehriz and sampling was performed in each of them bimonthly...

Five common tetracycline resistance genes tet(A), tet(B), tet(M), tet(O) and tet(S) were studied by polymerase chain reaction in 100 bacteria isolated from Iranian fish farms. In the antibiogram test most of the bacteria were either intermediately or completely resistant to tetracycline. Nine isolates out of 46 Aeromonas spp. contained either tet(A/M/S) resistant genes as follows: tet(A) in A. ...

The northern Gulf of Aqaba is an oligotrophic water body hosting valuable coral reefs. In the Gulf, phytoplankton dynamics are driven by an annual cycle of stratification and mixing. Superimposed on that fairly regular pattern was the establishment of a shallow-water fish-farm initiative that increased gradually until its activity was terminated in June 2008. Nutrient, water temperature, irradi...

Poultry farms for meat or egg production is considered to be a huge business. However, waste including manure can give biogas that can produce electricity. In Pakistan load shedding problem remains throughout the year, therefore biomass being the cheap and efficient fuel for power generation can overcome this problem. This research has been conducted in Abbottabad district of Khyber Pakhtunkhwa...

Existing task assignment policies proposed for assigning tasks in stand-alone server farms are not efficient in multiple server farm environments because they have not been designed to exploit the properties of such environments.With the emergence of high speed networks and operating systems that have features such as preemptive migration, the importance of designing task assignment policies fo...

In face of gradual ecological deterioration, the Chinese government has been in search of more efficient and effective mitigation policies, aiming to promote the sustainability of livestock production. However, researchers and policy makers seem to neglect a key issue: pinpoint policies are the most important, which means niche targeting is the premise before any policy design, such that better...
