响应面法优化碱性蛋白酶提取野生山核桃籽粕蛋白

为研究响应面法优化碱性蛋白酶提取野生山核桃籽粕蛋白质的工艺,在单因素试验的基础上考察了加酶量、pH值、提取温度和提取时间等条件对蛋白质提取率的影响。采用Box-Behnken Design试验设计,进行四因素三水平的中心组合试验,建立了蛋白质提取率与各主效因子的二次回归模型方程。结果表明,最佳提取条件为加酶量4．0％、pH12．0、温度47℃、提取时间2．0h。在此条件下,蛋白质提取率可达81．90％。     

The value of plant genetic diversity to resource-poor farmers in Nepal and Vietnam

Genetic resources for food and agriculture are the biological basis of world food and nutrition security; and they directly or indirectly support the livelihoods of over 2.5 billion people. Genetic diversity gives a species or a population the ability to adapt to changing environments. For resource-poor farmers, adaptive animal breeds, crop varieties and cultivars adapted to particular micro-niches, stresses or uses are the main resources available to maintain or increase production and provide a secure livelihood. The economic value of genetic diversity for productivity and yield traits is discussed in the literature. However, it is difficult to value many other aspects of agricultural biodiversity as these have both direct and indirect values in terms of qualitative traits such as food, nutrition and environmental uses that include adaptation to low input conditions, co-adaptive complexes, yield stability and the consequent reduction of risk, specific niche adaptation, and in meeting socio-cultural needs. Together, the direct and indirect values of genetic resources for resource-poor farmers are expressed in a range of options in the form of the crop varieties and species they use for managing changing environments.

The value of genetic diversity to resource-poor farmers is seldom captured by markets or addressed by the international research agenda. This paper presents lessons learned from our work over 5–10 years in the Asia and Pacific Ocean (APO) region on participatory crop improvement, home gardens and on-farm management of agricultural biodiversity. The lessons illustrate how farmers adapt genetic resources to suit local environmental conditions. The paper focuses on the value of genetic diversity of selected crop species to meet people's food and other needs. Genetic diversity valued by resource-poor farmers is often maintained, selected and exchanged by local social seed networks. Identification of such genetic resources and their custodians is important if international agricultural research is to contribute to the reduction of poverty. The paper highlights some good practices from case studies that illustrate how such genetic resources could be exploited by informal research and development strategies or participatory plant breeding or for marketing value-added products.

论破坏国家重点保护野生动物资源的犯罪

《野生动物保护法》将珍贵、濒危野生动物列为国家重点保护的野生动物 ,并规定了管理、保护制度。 1 997年《刑法》新增了非法猎捕、杀害珍贵、濒危野生动物罪和非法收购、运输、出售珍贵、濒危野生动物、珍贵、濒危野生动物制品罪 ,从而完善了我国对野生动物的法律保护体系。本文就两个罪名的法律构成 ,以及司法实践中的有关问题展开讨论。     

太行山野猪不同杂交组合生长及屠宰性能测定

选择体重30kg左右的太行山野猪与长白猪、汉普夏、上海白猪的杂种猪分为9组,每组12只,公母各半,进行饲养试验,测定太行山野猪不同杂交组合的生长性能。饲养试验结束后,每组随机选择4头屠宰,进行屠宰性能测定。结论:①野猪血缘含量越高,生长性能越低。②长白猪与野猪的杂交组合比其他杂交组合有较好的生长性能。③野猪血缘含量越高,瘦肉率越高。④汉普夏猪与野猪的杂交组合比其他杂交组合有较好的屠宰性能。

Work–life balance: a longitudinal evaluation of a new measure across Australia and New Zealand workers

The work–life balance literature has recently identified the need for construct refinement. In response to these discussions, this research describes the development and validation of a concise measure of work–life balance, based on individuals' subjective perceptions of balance between their work and other aspects of their lives. The structure, reliability and validity of this unidimensional, four-item measure was confirmed in four independent heterogeneous samples of workers employed in Australia and New Zealand (N = 6983). Work–life balance was negatively associated with work demands, turnover intentions and psychological strain, and positively associated with both family and job satisfaction, confirming the research hypotheses. Evidence of these relationships over time was also demonstrated. This research confirms that this new measure of work–life balance demonstrates robust psychometric properties and predicts relevant criterion variables.

纤维风积沙土归一化特性分析

基于纤维风积沙土的不固结不排水三轴剪切试验,为实现应变硬化型纤维风积沙土应力—应变关系的归一化,基于应变硬化型典型的双曲线特征,提出了以固结围压作为归一化因子。通过以固结围压为归一化因子,对纤维风积沙土应力—应变特性进行归一化分析和比较表明,纤维风积沙土的应力-应变特性归一化程度更高,效果更好。同时,建立了应变硬化型纤维风积沙土应力—应变特性的归一化方程。
