A detailed model was developed for the emulsion copolymerization of styrene and MMA to predict the evolution of the particle size distribution (PSD) and molecular weight distribution (MWD) over the entire range of monomer conversion. A system exhibiting zero-one kinetics was employed. The model was used to optimise the emulsion copolymerization process in order to maximize particle size polydis...

The effects of variable moisture content, screw speed and barrel temperature on the physicochemical properties of red ginseng powder extrudates were investigated. The raw red ginseng powders were processed in a co-rotating intermeshing twin-screw extruder. Primary extrusion variables were feed moisture content (20 and 30%), screw speed (200 and 250 rpm) and barrel temperature (115 and 130°C). E...

BACKGROUND AND AIM In today era, broiler industry facing a problem of price hiking of feed of broiler, also in competitive era there should be lower feed cost, lower feed conversion ratio, low feed consumption yet good body weight at marketable age. MATERIALS AND METHODS Day-old commercial broiler chicks (n=200) were distributed randomly into 5 dietary treatment groups viz. control (T1), prob...

this experiment was conducted with broiler chickens to evaluate the effects of high and low swelling bentonite (natural and processed by cuso4) supplementation in diets on performance and carcass traits. a total of 300 day-old aryan broiler’s chicks were used in a completely randomized design with 5 dietary treatments. six pen replicates of 10 chicks were assigned to each of five dietary treatm...

variation in growth, feed utilization and survival was assessed in sturgeon fingerlings of beluga fed different dietary lipid levels. all diets were iso-nitrogenous (protein = 45%) comprising 3.4-3.7 kcal digestible energy g-1. triplicate groups of 35 fingerling beluga with a mean initial wet weight of 2.14 ± 0.07 g (± sd) were fed with four experimental diets containing 6.7, 10.5, 14 and 17% c...

Feed costs are a major cost component of pig production and the optimal use of feed for production is therefore of high importance in an economic and sustainable pig industry. The amount of food eaten by the growing pig is used for maintenance and growth which includes lean meat as well as fat growth. The aim in pig production is to produce lean meat most efficiently which is achieved by optimi...

in this study 60 arian male chickens for six weeks were used in a completely randomized block to evaluate the effect of three dietary energy level on performance and prevention ascites. diets energy levels were: as catalog; 100 and 150 kcal lower in starter and grower and finisher periods; 200 kcal and 300 kcal lower in starter and grower that catalog respectively. during the experiment, body w...

Hydroprocessing has become the main technology for the production of API Group II and III base oils. One of the key properties is viscosity index for Group II and III base oils. The effect of wax content in hydrocracker unconverted oil on viscosity index and yield was studied in a 400 kton/year hydroisomerization dewaxing plant at a total pressure of 15 MPa, a feed rate of 38 ton/hour, and a ga...
