an experiment was conducted to evaluate the efficacy of exogenous enzymes supplementation (es) on performance, carcass traits and some blood parameters of broilers chickens. one hundred and eighty day old chicks with 40 ± 2 g initial body weight in a completely randomized design with 3 treatments and 4 replications were fed experimental diets included, 1) basal diet no enzymes (control), 2) bas...

This study deals with artificial neural network (ANN) modeling a diesel engine using waste cooking biodiesel fuel to predict the brake power, torque, specific fuel consumption and exhaust emissions of engine. To acquire data for training and testing the proposed ANN, two cylinders, four-stroke diesel engine was fuelled with waste vegetable cooking biodiesel and diesel fuel blends and operated a...

intake system design as well as inlet ports and valves configuration is of paramount importance in the optimal performance of internal combustion engines. in the present study, the effect of inlet ports design is investigated on om-457la diesel engine by using a cfd analysis and the avl-fire code as well. a thermodynamic model of the whole engine equipped with a turbocharger and an intercooler ...

this study was conducted to investigate the effect of aflatoxin b1 (afb1) on performance and egg quality in broiler breeders and the abatement of its deteriorative effect through its counteraction with herbal mycotoxin binder (hmb). thirty-six, 28-wk-old broiler breeder hens were allotted to one of the three treatments of: (1) basal diet (control),(2) control plus 500 μg kg-1 afb1 and (3) contr...

One of the issues that impair the performance of aircraft engine fault diagnosis is the flight regime. When an aircraft travels from one point to another in flight regime, engine performance parameters that are used for fault diagnosing change and such changes mask the parameter changes caused by engine faults, thus make the engine fault diagnosis much more difficult. Properly addressing the fl...

Increased energy demand and the concern about environment friendly technology, renewable bio-fuels are better alternative to petroleum products. In the present study linseed oil was used as alternative source for diesel engine fuel and the results were compared with baseline data of neat diesel. Performance parameters such as brake thermal efficiency (BTE) and brake specific fuel consumption (B...
