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 ...

twenty eight lactating buffaloes were used in a completely randomized design with 2×2 factorial arrangement of four experimental diets including low protein–low energy (lp-le), low protein–high energy (lp-he), high protein–low energy (hp-le) and high protein–high energy (hp-he). results showed that the hp-he diet recorded the highest digestibility coefficients of cp, ee, nfe, nutritive values, ...

the effect of colistin sulfate on reducing salmonella enteritidis (s.enteritidis) infection in broilers and contamination from broiler carcasses was evaluated. 40000 birds in two separate houses were considered. colistin sulfate was added in to the feed of the test group as 100g containing 1,200,000iu/ton of feed for the whole period (56 days). to isolate s.enteritidis, samples were taken from ...

watermelon seed full-fat (wmsf) and watermelon seed meal (wmsm) samples were analyzed for proximate composition and then incorporated in broiler chicks diets at increasing levels up to 20%. feeding increasing levels of wmsf to broiler chicks for up to 20% increased weight gain (p

the effect of a commercial probiotic (protexin) on growth performance and survival rate in sobaity sparidentex hasta was investigated. 240 fish with average weight of 2.99±0.87g were treated for 10 weeks. this study was carried out in a completely random design with 12 experimental groups, in 4 treatments each with 3 replicates. experimental groups were consisted of four levels of 0.0, 0.5, 1.0...

The role of nickel as catalyst on the conversion of methane and ethylene in a gas phase flow reactor in the absence of oxygen is studied. In this study, nickel in its different forms is used as catalyst. The role of pressure, flow rate, and temperature on the conversion of feed gases is investigated. The experiments have been carried out in the presence and absence of the catalysts to measure t...

Fluid Catalytic Cracking (FCC) process is a vital unit to produce gasoline. In this research, a feed forward ANN model was developed and trained with industrial data to investigate the effect of operating variables containing reactor temperature feed flow rate, the temperature of the top of the main column and the temperature of the bottom of the debutanizer tower on quality and quantity of...

The effect of ochratoxin A (OA) on the body weight, feed intake, and feed conversion was investigated in broiler chicken fed dietary levels of OA at 0, 1, and 2 ppm for 28 days from hatch. Feeding OA significantly reduced the growth rate of broiler chicken. The reduction was observed from the first week onwards in OA-treated groups. Feed consumption and feed conversion also showed a diminishing...
