Analysis of VCR images of pre-oviposition and oviposition behaviour of Culex quinquefasciatus (Diptera: Culicidae) females,in the laboratory

The aim of this work was to study the pre-ovipostion and oviposition behaviour of gravid Culex quinquefasciatus females, under laboratory conditions. Preliminary tests showed that oviposition is initiated from the third day after bloodfeeding and occurs in the first two hours and the eighth to the tenth hour of scotophase. Image analysis showed that females presented different types of exploratory flights, and that the most common was touching the hay infusion with their hind legs, while flying. The two main oviposition behaviours observed were: (1) females that land at the container's inner wall, rub one leg against the other and walk towards the interface between the wall and hay infusion surface to lay the egg raft; (2) females that land on the hay infusion surface, keep four or six legs on the surface, and lay the egg raft. Interestingly, females that touched the hay infusion with their proboscis rejected it as an oviposition substrate.     

Alkalosis and renal excretion of ammonia by rat kidney

Summary Upon sulfate administration, U_pH falls more in alkalotic rats than in controls. Alkalosis can lead to a reduction in U_{NH 3}V at highly acidic urine. The significance of this process is doubtful at U_pH ranging from about 6 to 7. At lower U_pH less NH₃ would be excreted, thereby less H⁺ would be trapped in urine and some acid would be conserved.

磁化水在煤层注水中的应用

为了防止煤与瓦斯突出、冲击矿压等灾害，预防自然发火等，探讨了磁化水的性质、磁场作用机理及磁技术在煤层注水方面的应用前景。研究结果表明，必须在合适的磁场作用下水的表面张力才能降低到最小；磁处理后，可以明显减少水中某些元素，这对于减少矿井水对管道的腐蚀具有重要意义：磁化水能够增加煤岩体的饱和吸水量，增加水在煤岩介质中的渗透性。磁场作用机理主要表现在可以使水分子缔合体分解成为单分子水或较小的缔合水分子，使水分子键长、键角加大，使水的活性增加、黏性降低。磁化水在煤层注水方面具有良好的应用前景。     

补液与运动能力的研究

研究脱水对人体的生理功能、体力表现和健康具有的危害,认为确保运动者身心健康,有规律地补液预防脱水是绝对必要的.从补液相关成分分析入手,对补液的时间等方面进行分析,研究掌握合理的液体补充方法,旨在提高运动员机能水平和抗疲劳能力.     

煤层注水的防突机理分析

应用关于突出机理的球壳失稳理论分析了煤层注水在防突中的作用结果表明,煤层注水的防突作用不在于水分对煤层内瓦斯的封堵,而在于煤层注水降低了硬煤分层的强度,增加了硬煤分层的塑性,由此导致整个煤层软化,工作面前方产生一个较长的破裂带和卸压带,使得具有突出危险的软分层内瓦斯能够在暴露前提前释放因此,注水钻孔应该布置在硬煤分层内,并使硬煤分层内水分均匀渗透,才能获得较好的防突效果图2,参4
