Steam reforming integrated with oxidation of methanol was considered with numerical simulation. The parallel micro-channels with circular cross sections were used. Because when the catalytic deposited inside the rectangular micro-channels, it fills up the edges. Hence, the approximation of a cylindrical channel is appropriate. Effect of this changing in cross section was considered and results ...

Six hundred 1-d-old male broilers (Ross 308) were assigned to four experimental groups; each was composed of 5 floor pen replications of 30 birds including control (no enalapril), 15, 30 and 60 ppm enalapril in the drinking water. From d 21 to 49, all the chicks were exposed to low ambient temperature to induce ascites. Mortalities were inspected to determine the cause of death and diagnose of ...

in this experiment, randomized complete block design with four replications was used for evaluating of the effect of three feeding methods including: without feed restriction (control group), 6 hours feed restriction from 7 to 21 days and 4 hours from 22 to 28 days, 6 hours feed restriction from 7 to 14 days and 4 hours from 15 to 21 days on performance and ascites prevention of arian male broi...

the present study tried to investigate the effects of probiotic, pediococcus acidilactici in concentrations of 1× 109, 2× 109 and 3×109cfu kg-1 diet on growth and survival rate of oriental bream fry (abramis brama orientalis, berg 1949) in comparison to control diet (devoid of probiotic) for 60 days. in so doing, 180 specimens of oriental bream with initial weight of 2.69± 0.22 g were divided r...

in order to investigate the growth curve of broiler chickens at line level, respectively 154 and 144 birds from two paternal lines a and b of a commercial broiler line were used. line a were selected several generations for low feed conversion rate and line b were selected several generation for high body weight. body weight was measured at 1, 4, 7, 10, 14, 17, 21, 28, 35, 42, 49 and 54 days of...

this study was conducted to determine the optimal dietary protein requirement for lemon fin barb hybrid fingerlings. triplicate groups of fish (1.00 ± 0.05 g) were fed twice a day until apparent satiation with five isocaloric (16 kj/g) diets containing varying protein level ranging from 20 to 40% for 60 days. survival was not affected by the dietary protein level. the weight gain and specific g...

Objective: This study was conducted to evaluate the effects of different proportions of marshmallow extract (Althaea officinalis L.) on growth performance and carcass composition of common carp (Cyprinus carpio). Methods: Common carp with an average weight of 37.65 ± 4.40 g were fed for two months with a diet supplemented with marshmallow (A. officinalis) ext...
