the present study is an attempt to investigate the potential impact of inspirational quotes on improving english abstract vocabulary recall. to achieve this goal, a multiple choice language proficiency test of 60 items including vocabulary and grammar component was administered to a sample of 63 second-semester male and female students whose age ranged between 17 to 22 and they were studying en...
We evaluated the effect of wet corn gluten feed and a novel product containing raw soybean hulls and corn steep liquor on performance in lactating dairy cows. Forty-six multiparous Holstein cows were used in a randomized incomplete block design. Cows were housed in tie stalls for the first 13 weeks of lactation and moved to group pens for the remainder of the study. Cows were blocked by calving...
In a previous report by Kennedy and Speck (1955), it was shown that the addition of corn steep liquor to milk stimulated the growth of several species of lactic acid bacteria. Additional studies (Kennedy et al., 1955) have shown the stimulatory factor to be different from other stimulatory factors reported for the lactic acid organisms. These investigators also observed that corn steep appeared...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
Biosurfactant production optimization by Candida tropicalis UCP0996 was studied combining central composite rotational design (CCRD) and response surface methodology (RSM). The factors selected for optimization of the culture conditions were sugarcane molasses, corn steep liquor, waste frying oil concentrations and inoculum size. The response variables were surface tension and biosurfactant yie...
The stimulation by yeast extract of acid production in milk by various lactobacilli was studied. It was found that supplementing milk with purine and pyrimidine bases and amino acids allowed nearly maximal acid production by Lactobacillus bulgaricus strain 7994, L. acidophilus 4796, 4356, and 4357, and L. leichmannii 326 and 327. Further supplementation with deoxyribotides allowed maximal acid ...
production of oxytetracycline by an isolated strain of streptomyces rimosus from iranian soil was investigated using a special fermentation medium. a comparative study was performed with standard strain ptcc 1144 using the following parameters optimum growth conditions with respect to time, ph, and different amounts of corn steep liquor. surprisingly, the production yield of the wild strain was...
now-a-days graphic design plays a major role in influencing culture, society, business, and customers, in such a way that one could look upon every individual as a potential customer. graphic designers seek to identify customers needs and find an intelligent solution for them. correct identification and understanding of those needs is the first step towards achieving ones goals. marketing knowh...
During the course of a screening program for antibiotics produced by a Saccharothrix, two new kinamycins 1 and 2 have been isolated from cultured broth of strain MI293-N4. They inhibit the growth of Gram-positive bacteria and neoplastic cells. This paper describes the production, isolation, purification and the structure elucidation of the antibiotics. Some physicochemical properties and biolog...
