This study was conducted to investigate the effect of canola seed (raw and roasted) and diet concentrate levels on growth performance and quantitative and qualitative characteristics of carcass of Lori male lambs. A total of 54 male 30±0.86kg lambs were selected for the experiment. Treatments consisted of two levels of canola seed (raw and roasted) and three levels of concentrate (60, 70 and 80...
background and objective : mozzarella is a soft cheese belonging to the pasta filata family, containing 18-24 % fat. the objective of this study was to determine the effect lowering mozarella fat content to 6% and adding whey protein concentrate on the rheological properties of the low-fat cheese. materials and methods : low-fat mozzarella was produced using 3 fat replacers ( dairy-lo, 35% prot...
preparations of platelet concentrates (pcs) that are stored under blood bank conditions and used for transfusion purposes, appear to be enriched in platelet derived-microparticles (pmps) with high coagulant activity that may change platelet efficacy and safety issues. high shear stress could cause shedding of pmps from the platelet plasma membrane, platelet aggregation, and activation of the co...
In this study the effect of non alkohalic beer concentrate was investigated on the expression of growth hormone (GH), insulin growth factor1 (IGF1) genes and skin mucus immunity (Ig and ALP) in common carp. 180 pieces of common carp with average weight of 12.5 ± 2 g, were fed experimental diets supplemented with different levels of non alkohalic beer concentrate (0 [control], 0.5, 1 and 2%) (4 ...
Cyclic voltammetry and potentiodynamic polarization analyses were utilized to investigate the mechanism kinetics of glycine leaching reactions for chalcopyrite. The effects pH (9–12), temperature (30–90 °C) concentration (0–2 mol/L) on corrosion current density, potential cyclic voltammograms investigated using chalcopyrite concentrate–carbon paste electrodes. Results showed that an increase in...
The current treatment of haemophilia with coagulation protein replacement therapy is both effective and safe. Nevertheless, this therapy requires frequent, repeated intravenous infusions and approximately 25% of treated haemophilia A patients develop antibodies to the replacement protein. Furthermore, the cost and limited availability of current concentrates has restricted access to therapy to ...
Call a sum of exponentials of the form f(x) = exp (2πiN1x) + exp (2πiN2x) + · · ·+ exp (2πiNmx), where the Nk are distinct integers, an idempotent. We have L interval concentration if there is a positive constant a, depending only on p, such that for each interval I ⊂ [0, 1] there is an idempotent f so that R I |f (x)| dx R 1 0 |f (x)| dx > a. We will explain how to produce such concentration f...
The investigation was expected to assess various mineral mixture supplementation impacts on Brahman crossbred cows' blood biochemical, hematological profiles and pregnancy rate. This study used ninety cows divided into three dietary treatment groups (n = 30/group). treatments were: Concentrate rice straw only as control treatment; diet + A-formulation MM-A B-formulation MM-B treatment. concentr...
Abstract Chalcopyrite (CuFeS 2 ) is the most refractory copper mineral when treated in conventional sulfate media leaching systems. This first study to examine use of a dimethyl sulfoxide (CH 3 SOCH , DMSO) solution containing chloride (CuCl for chalcopyrite. Leaching experiments concentrate composed mainly chalcopyrite were conducted at ambient pressure 313–413 K. The fractions Cu, Fe, S, Au, ...
