The recovery of high-quality, valuable end products from cheese whey is a very important industrial process. The aim of this study is to improve the recovered protein content of concentrate stream in cheese whey. The experiments were conducted by using ceramic ultrafiltration (UF) membrane followed by diafiltration (DF) process with a 15kDa molecular weight cut-off (MWCO). The volume concentrat...

background: recently the role of platelets in the tissue regeneration, wound healing and prevention and control of infections has been reported. we aimed to assess the antimicrobial effect of human platelet concentrate against six bacteria, commonly found in wound and hospital-acquired infections. methods: in vitro susceptibility to samples of 10 random human platelet concentrates was determine...

this study was conducted to evaluate the effects of extruded linseed on milk production, dry matter intake and reproduction performance of 300 holstein lactating cows (35±15 days in milk; 41±9/8 kg/day of milk production). cows were utilized in a completely randomized experimental design, comprised of: 2 treatments (concentrate containing 7 percent extruded linseed vs control) with a number of ...

sixteen rams (mean age: 13 mo; mean live weight: 40.0 ± 2.4 kg) were randomly allotted to four dietary treatments in a completely randomized design (4 rams per treatment). diets (dry matter basis) contained 65% concentrate and 35% alfalfa hay (control diet, t1), 35% wheat straw (t2), 35% barley straw (t3) or 35% maize straw (t4). total-tract apparent digestibility for dry matter, organic matter...

binders are of prime importance in the agglomeration of iron ore concentrates. in this research, strength and density of briquette produced from the magnetite concentrate of gol-e-gohar were investigated using different binders at various applied pressures. the results showed that peridor was the most effective binder relative to bentonite and lime. for all types of binders, the increase in bin...

The Wushan Operation has been studied as a case study, particularly relevant to the copper-molybdenum separation circuit, in which efforts have made improve quality of molybdenum concentrate through diagnostic analysis. A key finding appearance coarser silicate minerals due their inadvertent activation flotation. suitable flotation conditions occurs, most likely, upstream bulk regarding usage n...
