modern hydrometallurgical techniques have been adopted to produce high-purity gold. many extractants were used for the extraction of gold from various synthetic solutions from which dibutyl carbitol (dbc) had a unique superiority. kinetics of process was studied in this paper and the influence of several parameters such as stirring speed, agitation time, impeller type, interfacial area, [aucl4]...

A 21-year-old man walked into the ED complaining of mild headache after colliding with another player during a baseball game. The patient denied loss of consciousness and noted numbness over his left forehead. He denied vision change, fluid from his nose or ears, dizziness or other injury. He had normal mentation, no neck pain, and an otherwise non-focal exam. He declined pain medication. A vis...

BACKGROUND Several monoclonal antibodies (mAbs) recognising Lewis(y), such as BR96, have reached the clinic but have failed to show good anti-tumour responses with an acceptable level of toxicity. No Lewis(b) mAbs have been trialled in patients. In this study we compare the specificity of three mAbs; BR96 (Lewis(y)), 2-25 LE (Lewis(b)) and 692/29 that recognises a unique facet of both Lewis(y) ...

Genetic correlations (r ) between Lifespan (LS) and conformation traits in the Ayrshire breed were obtained from data on g 8087 heifers which calved between 1976 and August 1990. The r were estimated from a series of multivariate analyses g applying an animal model restricted maximum-likelihood procedure. The genetic relationship between LS and somatic cell counts (SCC) was studied in the Holst...

Two types of cytochrome P450 2D14 (CYP2D14) gene deletions (GD1 and GD2) in Japanese Black cattle has been reported by us. In this study, we determined the frequency of cytochrome P450 2D14 (CYP2D14) genetic polymorphisms in 48 Japanese Black (JB) and 48 Holstein-Friesian (HF) cattle using polymerase chain reaction (PCR)-direct sequencing. Two types of CYP2D14 gene deletion variants, GD1 and GD...

Under tropical condition the BCS may influence the feed intake and metabolism leading to variation in economic parameters. This study investigated the BCS as a regulator of milk yield (MY) and composition (MC) in dairy animals. A total of 154 animals, comprising Azakheli (AZ) and Nili-Ravi (NR) buffaloes, Holstein Friesian (HF), Jersey (JC), Sahiwal (SW), Achai (AC) and crossbreds (XB) cattle a...

Introduction Investigating and comparing the two systems Comparing some technical efficiency ratios and profit Points to note about the comparison Conclusions References Abstract. In this study, budgets of herd dynamics, feed and energy supply, production and profit of alternative dairy farm systems were used to examine the effects of changing a 230 cow Holstein-Friesian (HF) dairy system to a ...

Considering the high incidence and mortality rate of esophageal cancer in some areas of the country, and its diagnosis at a time of advanced growth, this study was carried out to determine the predisposing factors and the most effective and applicable surgical procedure. In this descriptive study, 158 patients (95 males and 63 females) with esophageal cancer were studied. They referred to Shoh...
