大豆蛋白非食品应用研究

大豆蛋白是大豆的主要农产品之一,主要在材料粘合剂、生物降解膜和塑料材料、纤维材料和生物医用材料等几个领域研究较多。随着目前全球性环境问题和石油资源的日益紧张,天然高分子材料的开发成为21世纪科学工作者研究的热点课题。文章就大豆蛋白在非食品方面的应用展开叙述,总结了大豆蛋白在胶粘剂、大豆蛋白膜、大豆蛋白塑料、大豆蛋白纤维和生物医用材料方面的应用。     

动物对温度适应的分子生物学研究进展

动物对环境温度的适应,会使自身的细胞内转录和表达模式发成变化,以适合环境的变化,此时它会出现新的基因开放和新蛋白因子的合成,这总的来说是动物对自身的一种保护方式。本文从基因水平、蛋白质水平、细胞膜水平等三个方面综述了动物对环境温度适应的研究概况,并讨论了动物对环境温度适应的分子生物学机制以及在进化中的意义。     

KDN型定氮仪测定粮食中粗蛋白质含量的相关问题探讨

目前测定蛋白质的方法和仪器很多,为了提高蛋白质含量检测结果的准确性和检测效率,依据GB/T 5511-2008《谷物和豆类氮含量测定和粗蛋白质含量计算凯氏法》要求,常用定氮仪来测定粮食中粗蛋白质含量。对此方法中化学试剂硫酸的选择及实际操作进行了探讨。

卞之琳是中国现代诗歌史上智性诗歌写作的代表诗人,他吸收了西方象征主义诗歌理论,并将之与中国古典诗美相结合,创造了独具特色的诗美风格。《断章》是他的代表诗作,因其丰富的诗美含量而引发了对之众多版     

流动性危机:入世后我国商业银行面临的最大冲击

加入WTO以后,我国银行业受到的冲击将是多方面的,其中以国有商业银行受到的冲击为最。本文从分析目前我国四大国有商业银行的不良资产的规模过大,比例太高的状况出发,认为在外资银行的冲击下,如果我国银行开放措施稍有不当,将对我国商业银行流动性产生最大冲击,造成商业银行的支付困难,有可能引发金融危机。最后认为减少冲击,化解危机的关键应从化解不良资产入手,并提出具体的对策建议。     

Large-scale participatory co-shaping of technological developments: First experiments with PARDIZIPP

A future-oriented participatory procedure on the basis of the Delphi method was developed and empirically tested a first time with the goal to improve the shaping of technological developments. The technology under study here was micro-electronics or rather their relationship with labor and the test took place in NorthRhine-Westphalia.Today problems exist in all walks of life. There is a lot of talk about today's problems as if they were new, though one has heard similar arguments throughout history. How do we assess if we are really in danger of bringing the world to an end? Although this danger appears real, it would not be the first time in history that people have thought and felt like this--However, one thing that is new are the consequences of modern sciences and technology, which are not suited to given social and environmental requirements. They have given rise to questions concerning the quality of the decision-makers. The questioning of many of these decisions has increased for some time and is now getting more and more specific, with a demand for quality and information rather than managerial skills and competitiveness from the decision-makers. The term ‘decision-maker’ describes those who determine the application of technology, science and technical equipment which has either existed for a long time already or has recently been developed.--It is not easy to change the structures and processes of decision-making so that new structures and processes will be more suited to social and environmental requirements. We have tested our ideas as to how this could be done, in an empirical project. Although we called it ‘Project NRW-2000’, it would probably be better described as an experiment.--We persuaded 90 ordinary people to participate in this project as ‘experts on daily life and work’. This group was asked to work in six regional sub-groups and discuss, with reference to three given normative societal scenarios for the year 2020, the relationship between microelectronics and labour markets of the year 2020, on the basis of a participatory Delphi procedure. Before we elaborate on the concept of our project in Section 3, we would like to outline it in terms of the mainstream of the sociology of technology as well as with research on ‘acceptance’ in Section 1. In Section 2 we will briefly illustrate the framework of the research programme ‘Socially Oriented Shaping of Technology’ of the state of Northrhine-Westphalia, which funded our research project. Section 4 particularly deals with the participatory elements of our project, while Section 5 is devoted to the development of the scenarios. Section 6 sums up the results of the ‘scenario-construction’. Regarding specific elements, we restrict ourselves to topics concerning technology, labour, and the relationship between women workers/employees and technology. As a final outlook we deal with the political implications of our approach. All that is left is to remind our readers that we regard this project as a first application or experiment within our overall approach.     

AX与面粉品之间的关系

本采用不同品种的小麦为原料,首先通过测定小麦籽粒和面粉的品质特性及其阿拉伯木聚糖(AX)含量,对AX含量与小麦粉品质间的关系进行探讨。主要研究结果如下:(1)对小麦品质指标的测定,结果显示不同品种的小麦籽粒间存在较大的差异。面粉中AX含量与蛋白(r=0.27)、麸星含量(r=-0.16)存在存在一定的正相关,而AX含量与白度和降落数值存在微弱的负相关,面粉中AX中含量与面粉的吸水率、面团的形成时间、面团的稳定时间和弱化度呈弱相关性,相关系数分别是r=-0.34、r=0.27和r=-0.09;(2)不同的面粉中AX含量与峰值粘度呈显著负相关,与最低粘度、最终粘度呈弱负相关,当面粉中AX含量增加时,峰值粘度、最低粘度、最终粘度都会降低;峰值粘度与最低粘度、最终粘度呈显著正相关。
