大学生行使学习权利的教育价值

大学教学如何体现以学生为本,促进学生能动学习,提高教育教学质量是当前高校教育工作者所关注的问题。学生应行使学习权利中的“知情权”“参与权”和“建议权”,体现以学生为本、实现学生能动学习和提高教育教学质量方面的价值。行使知情权,构建以学生为本的教育教学平台;行使参与权,培养学生能动做事、做人和做学问的能力;行使建议权,在激励中实现教育教学质量的提高。

Characterization of pH-sensitive Poly （ acrylic acid-co-N-vinyl-2-pyrrolidone） Hydrogels Prepared by Gamma Radiation

The pH-sensitive copolymer hydrogels were prepared with the monomers of acrylic acid and N-vinyl-2-pyrrolidone based on gamma radiation technique. The morphology of the hydrogels was monitored by using scanning electron microscope. The influence of absorbed dose, monomer compasition and concentration on the swelling ratio (SR) of the hydrogels were investigated in detail. The effect of pH and temperature of the swelling medium on the swelling behavior of the hydrogels were also examined. The results show that the SR of the copolymer hydrogels decreases with the monomer concentration and absorbed dose increasing. The copolymer hydrogels show a better pH-sensitive behavior. In alkaline solution, the SR of the hydrogels is much higher than in acid solution.

交互满意方法在多目标模糊非线性规划中应用

在运用浮点遗传算法的多目标全系数模糊非线性规划中,提出交互模糊满意方法.引入α-水平集把MOFNLP转化为α-MONLP.通过线性隶属函数量化.给出具体的α水平度和参考隶属度,利用浮点遗传算法解最小值问题得到Pareto最优解,并通过调整α水平度和参考隶属度使决策者从多个Pareto最优解中得到满意解.     

Demonstration of retinoic acid isomers in human urine under physiological conditions

Untransformed retinoic acid has never been demonstrated in human excreta under normal physiological conditions. We have developed a two-step liquid chromatographic system for the demonstration of subnanogram amounts of this compound in human urine without administration of any precursor.     

Observations on the toxicity and metabolic relationships of polygodial,the chemical defense of the nudibranchDendrodoris limbata

Summary Polygodial (1), the defense metabolite stored in the skin of the nudibranchDendrodoris limbata, is toxic for the mollusc itself when injected into the hepatopancreas. Biosynthetic experiments using labeled mevalonic acid were devised to investigate a possible metabolic relationship between1 and the mixture of sesquiterpenoidic esters2, stored in the hepatopancreas. The results suggest that1 and2 are biosynthesized by independent pathways.Thanks are due to G. Villani for supplyingDendrodoris limbata and to A. Trabucco for technical assistance.
