The influence of polyunsaturated fat acids on the development of artificially caused exudative skin necrosis in rats

Development of exudative skin necrosis in female rats of Vistar line was caused by Selye method (with help of subcutaneons injections of sodium chlorate). The number of rats which got skin necrosis was bigger than when animals were fed on food containing butter or sardine fat, at that in the second case bigger than first one. The necrosis area in rats, which were fed on different rations, was the some.     

试论高校教师应发挥德育的主力军作用

当前,高等学校的主要任务是坚持正确的政治方向,全面贯彻党的教育方针.把德育放在首位。这是反对“和平演变”的重要战略措施。如何才能把德育放在首位,切实强化对大学生的德育工作,是高教改革的热点之一。历时一年的高校教书育人报告活动年初在北京达到了高潮,全国高校10个教书育人先进集体和23个     

谈谈玻璃钢

玻璃钢,目前在世界上还是一种新兴的工业产品.它具有很多特点,如机械强度高,超过软钢和铝;冲击强度大,超过多数金属;导热性低,绝缘性高,有较高的化学稳定性;它可以在很多用途上代替钢材,而重量比钢轻3到4倍;它还可以抵抗气候的变化,抗酸抗碱和抗多种化学药品的侵蚀;并能耐摄氏200度以上的高温.世界上好些国家都已经用它制造船艇、汽车、飞机的外壳和工业管道、矿井支架、透明楞瓦,以及代替各种钢材等.目前玻璃钢在各个工业部门的使用,仅是一个开端,将来进一步解决了它本身存在的一些缺点,更会有无限广阔的发展前途.我国目前对玻璃钢的生产,还处在一个研究试制阶     

Food supplements and medicines of vegetative origin. Safety estimation and standardization

The article describes the modern legislative and normative base of both Russian made and foreign made food supplements turnover. The main requirements to them. The reasons for banning the use of some particular ingredients in food supplements formula are substantiated. The ways of improving the normative base for food supplements as well as for medicines of vegetative origin are proposed. The conclusion is made, that this base is more perfect than for the medicines, produced from herbs.     

Sealed-cell mercury resonance ionization imaging detector

A sealed, compact mercury atomic-absorption resonance ionization imaging detector has been developed and evaluated. The sensitivity of the detector as well as its ability to form two-dimensional images has been demonstrated. Images of faint light (1000 photons) have been recorded by image summation. It is shown that one can obtain high-quality images with a spatial resolution of at least 130 mum by detecting the ionic component of the imaging signal. Distortion, more noise, and poorer spatial resolution were observed when the electron component of the signal was detected. We studied the influence of voltage on the cell electrodes to find the conditions for optimum signal-to-noise ratio.     

Food glycemic index and its application in the dietetics of obesity

A survey of literature data concerning dietetics in the management of excessive weight has been presented. Pathogenetic approach has been suggested in the choice of carbohydrate saturated food products in the complex management of excessive weight, taking into account carbohydrate adsorption rate determined by its glycemic index value.     

颤栗的传奇——迈克尔·杰克逊：透视迈克尔·杰克逊的称王与下坡

据说,在奥巴马（Barack Husse in Obama）当选美国总统那天夜里许多不知名的黑人为之流泪,因为他们感到美国终于也属于黑人的了。在一个曾经广泛存在种族歧视的国度,民权运动领袖马丁·路德·金的《我有一个梦》终于从梦想变成现实.     

云南是丰富音乐宝藏地

中国人应懂中国音乐，是理所当然的事。事实是否如此不打紧，最重要的是有这个认知，争取机会去多听、多接触、多了解中国音乐，假以时日，还有可能成为中国音乐专家呢。[第一段]
