pulmonary hypertension syndrome (ascites) is a metabolic disorder in fast-growing broilers. inconsistency of oxygen requirement and the cardiovascular ability make the birds susceptible to ascites. incidence of ascites was accompanied by right ventricular hypertrophy, fluid accumulation in the abdominal cavity and finally mortality. the objective of the current study was to review the genetic b...

an epidemiological  study  was carried out to determine the prevalence rate  and  significant cost benefit of various helminthes ( gastro-intestinal)  disease in cattle and buffalo population in two industrial husbandries in  north and south provinces of iran before and after treatment with oxyclozanide.  results show out of 450 fecal samples examined. 205 (37.96%) were found infected with oeso...

Objective(s): This study evaluates the effect of substitution of microcrystalline cellulose (MCC) with ethylcellulose (EC) on mechanical and release characteristics of theophylline pellets. Materials and Methods: The effect of addition of EC was investigated on characteristics of pellets with varying drug content prepared by extrusion-spheronization. Also the effect of type of granulating liqui...

among the various methods of clinical teaching, rounds and grand rounds are considered as the gold standards. clinical round includes some standard components and it plays an effective role in student's learning process. the aim of this study was to evaluate the content of teaching rounds in 40 clinical wards in 4 medical teaching hospitals affiliated to tehran university of medical sciences in...

Patients with pulmonary hypertension are at risk of developing fatal right heart failure after heart transplantation. To evaluate this risk potential, candidates for heart transplantation are screened by measuring rest right heart pressures and the response to nitroprusside. To test the validity of this approach, the influence of pretransplantation right heart catheterization data on outcome af...

This paper deals with the issues of observer-based reliable stabilization and H∞ control for a class of continuoustime switched Lipschitz nonlinear systems in the sense that actuators suffer a “destabilizing failure”. When the never-faulty actuators cannot stabilize the corresponding system, the closedloop switched systems can still be exponentially stable based on the average dwell time scheme...

Studies with (35)S-labeled substrates were conducted to investigate the pathway involved in the reduction of sulfite to sulfide by cell-free extracts of the sulfate-reducing organism Desulfovibrio vulgaris. The results showed that accumulation of thiosulfate occurred when crude extracts were incubated under appropriate conditions with sulfite as substrate. With labeled sulfite as substrate, thi...

Recently, the Italian government has approved a new law for public contracts and has been laying the groundwork for restarting a planning phase. The government has adopted the indications given by the European Commission regarding the estimation of the external costs within the Cost-Benefit Analysis, and has been approved the ‘Guidelines for assessment of Investment Projects’. In compliance wit...

the full annealing aa6061 aluminum alloy was subjected to severe plastic deformationvia the combination of equal channel angular pressing (ecap) and cold rolling (cr) in order torefine its microstructure and to improve its mechanical properties. according to the results of hotand cold tensile tests, the combination of ecap and cr significantly affected the final strengthand ductility of studied...
