Hygrothermal Response of Coconut Fiber Reinforced Composites

The effects of moist and temperature response of coconut fibre reinforced composite have been studied. Tensile and compression tests for samples immersed in 12.5 g/dm3 sodium hydroxide solution and without sodium hydroxide solution were performed using a universal testing machine （Monsanto tensometer）. The results from the tensile test indicate that stress is fairly proportional to strain. However, the tensile strength increases （reduction in strain）, as the soaking time increases for the treated composites. The untreated samples demonstrate reduced tensile strength compared to the treated composites under hygrothermal conditions. The conditioned samples in each case show better tensile and compressive strength compared to the untreated samples. The plant coconut fibres investigated demonstrate acceptable mechanical properties similar to the synthetic counterparts.

谷甾醇的提取及应用

一、概况 谷甾醇(Sitosterol)是一种混合性植物甾醇,其中主要为β—谷甾醇,另有少量其他饱和甾醇,广泛存在于小麦、玉米、黑麦、棉子、大豆和米糠等植物中。β—谷甾醇的化学结构类似胆固醇,所不同的是在胆固醇结构的24位支链上引入一个乙基。据国外研究结果认为:谷甾醇能降低实验动物和人体血清胆固醇浓度,有预防动脉粥样硬化的作用。

复合结晶氨基酸注射液原料(11种氨基酸)暂定规格

一、暂行规格基本上根据日本药典第九版(1976年)所载各种氨基酸的质量标准制定。精、组氨酸按国内颁布的标准制定。日本所订的标准并不高,为了有据可查,同时试制的氨基酸注射液是仿日本 Moriamm S—2的,故暂时按日本药典,以后可结合实际情况修订。
