The preparation of polypeptidyl proteins was first reported by Becker and Stahmann (l), who showed that the polymerization of N-carboxyamino acid anhydrides may be initiated by the free amino groups of proteins to yield the corresponding protein derivatives. Becker, Stahmann, et al., as well as a number of other investigators, have since reported on the physicochemical and biological properties...
abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
Calcium-bound phosphoryl oligosaccharides (POs-Ca) were prepared from potato starch. Their solubility and in situ absorbability as a calcium source were investigated by comparing with the soluble calcium compounds, calcium chloride and calcium lactate, or insoluble calcium compounds, calcium carbonate and dibasic calcium phosphate. The solubility of POs-Ca was as high as that of calcium chlorid...
Ustilagic acid is a water-insoluble glycolipid produced by Ustilago may&, the corn smut fungus. It was discovered by Haskins (l), and its structure was elucidated by Lemieux, Thorn, and Bauer (2, 3). Pilot plant quantities are being produced in Japan.’ Ustilagic acid was shown to be a mixture of acylated derivatives of /I-n-cellobiosyl-15u, l&dihydroxy-n-hexadecanoic acid (glucoustilic acid A) ...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
in this study the response of 9 rapeseed genotypes were evaluated at the seedling stage using different irrigation levels (50, 70 and 100% fc). a factorial experiment based on rcbd was conducted in the research greenhouses of urmia university with four replications during summer of 2013. some physiological traits such as relative water content, stomatal conductance, transpiration, photosynthesi...
