This study was carried out to compare the effects of ewe milk with commercial milk replacer and starter diet with different levels of concentrate on microbial protein synthesis, ruminal fermentation and blood metabolites in the suckling lambs. Thirty Dalagh breed male lambs were separated from their mothers on 3±1 days of age and divided into 6 groups (5 lambs per treatment), and reared in indi...
This study was conducted to evaluate the effect of different fresh feed supplemented to commercial diet on growth and survival of Oscar fish (Astronauts ocellatus) (initial weight: 1.58-1.70 g) during 60-day period. The husbandry environment consisted of glass aquariums appropriate to growth with a photoperiod cycle of 12 L: 12 D. The water temperature was kept at 28 ±1°C. 360 fries of Oscar (i...
A new process for recovering scheelite ores comprises producing a concentrate from the ore, then leaching the concentrate with H_2SO_4 in the presence of H_3PO_4 and Na Cl at atmosphericpressure are discussed. Finely purification of the product will be described. The amounts of dissolution of tungsten in acid depend on the parameters such as time, temperature, type and concentration of acid an...
background and aims: despite the screening of blood donors, blood transfusion represents an ideal port of entry for blood-borne infection. blood-borne pathogen transmission has been a concern since the earliest days of transfusion. the blood product of platelet (plt) concentrates is still faced with the risk of bacterial and viral contaminations. pathogen inactivation technologies offer a proac...
IN THE MID-1980S, THE PIONEERING work of Mario R. Capecchi, Sir Martin J. Evans, and Oliver Smithies (jointly awarded The Nobel Prize in Physiology or Medicine 2007) led to the development of gene knockout mice (e.g., Refs. 8 and 13). The use of gene knockout and transgenic mouse models has added essential information to our understanding of renal physiology, including the molecular mechanisms ...
