Background and Objectives: Red beet extract concentrate can be used as a natural colorant in food products; however, destructive effects of thermal methods to produce juice concentrate decrease nutritional value in the final product. Materials and Methods: In this study, red beet extract was concentrated using osmotic distillation method, and the best pretreatment was evaluated to increase t...

The objective of this work was to study the effect muscovite and biotite on flotation chalcopyrite molybdenite in seawater, use sodium hexametaphosphate silicate improve copper molybdenum recoveries. impact inorganic dispersants settling properties resulting tailings also studied. It found that depress with depressing being stronger at pH 11 than 9. Sodium increased recoveries seawater. These r...

Essential amino acids such as methionine have been increasingly included into diets of lambs. However, few studies have determined the effects of methionine supplementation in the general performance and economic returns of lamb production. To address this question, 21weaned male Rahmani lambs were allotted to 3 dietary treatments: control diet (C), control diet plus 3.30 g of methionine/kg con...

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...

the freeze-drying process. Continued viability of rehydrated cells during incubation at 37 C for 3 hours was dependent on the composition of the suspending medium. The number of viable organisms decreased greatly when suspended and incubated in water. Several salts were effective in maintaining higher viable cell counts. Maximum recovery of viable cells of one dried preparation rehydrated in ma...

The effect of concentrate mixtures with crude protein (CP) levels 10%, 13%, 16%, and 19% and diets with roughage to concentrate ratios 80:20, 60:40, 40:60, and 20:80 (w/w) were determined on dry matter (DM) and organic matter (OM) digestibility, and fermentation metabolites using an in vitro fermentation technique. In vitro fermented attributes were measured after 4, 24, and 48 h of incubation ...

the possibility of selective leaching process was investigated during molybdenite flue dust leaching to recover its rhenium content. the results show that addition of alcohols to water makes the medium less favorable for molybdenum transfer into aqueous phase. on the other hand, addition of small amounts of alcohols (5-15%) makes a noticeable separation of rhenium over molybdenum, but by increa...
