an experiment was carried out to evaluate how interactions between forage to concentrate ratio and dietary crude protein level may alter nitrogen efficiency and ut-b expression in growing baluchi male lambs. four baluchi male lambs [30 ± 2 kg bw] were used in a 4 × 4 latin square design with 28-d periods and a 2 × 2 factorial arrangement of dietary treatments. the treatments fed forage: concent...

this research was conducted to evaluate alteration of growth performance, nutrition, carcass and some serum biochemical parameters of common carp fed the diets supplemented by different levels of meal and alcoholic extract of alfalfa (medicago sativa). in this research, 300 fish (mean weight: 20.4 ± 0.19 g and mean length: 11.78 ± 0.64 cm) were fed by nine nutritional diets for 8 weeks. nutriti...

ABSTRACT In this work, the dry reforming of methane was studied using a corona and glow discharge plasma microreactors. A chemical kinetic model was developed to understand the reaction better. The modelization allowed prediction of the reactants conversion according to the energy transfer to the gas (P×τ). The β value is trait of the energy cost, whatever this value was leeser indicated ...

introduction activated sludge process is one of the most common methods used in wastewater treatment plants. regarding the large volume of sludge obtained from such biological wastewater treatment processes and considerable costs of its treatment and disposal, extensive research has been and is being done on novel effective methods of sludge stabilization. in previous investigations research gr...

this paper applied a non-parametric (data envelopment analysis) method to analyze the efficiency of farmers, discriminate efficient farmers from inefficient ones and to identify wasteful uses of energy in order to optimize the energy inputs for greenhouse cucumber production in lorestan province of iran. data were collected from 27 cucumber producers by using a face-to-face questionnaire.dea cr...

The response of laying Japanese quails to dietary levels of energy and protein on performance, egg quality, hatchability, fertility and their effect on subsequent offspring live body weight was investigated. A total of 432 Japanese quails (13 weeks old) were divided into nine treatments. Each treatment comprised of four replicates of twelve birds (9 females and 3 males). Nine diets including th...

Heat recuperation is often used to improve the overall cycle efficiency of gas turbines. However, generally in small- scale gas turbines, it has a negative effect on turbine inlet temperature, pressure ratio and pressure drops, and thus decreases the overall cycle efficiency. In this paper, a thermodynamic model is performed to evaluate recovered heat as a function of heat exchanger effecti...
