"食品微生物学"是高等院校食品科学与工程、食品质量与安全及其相关专业的一门必修专业基础课,该课程实验技术是食品类专业学生必须掌握的基本技能,而传统的实验教学存在着与就业岗位需求脱节、学生参与度低等诸多问题,难以培养学生独立完成岗位工作的能力。为了培养学生的综合实践能力,适应就业岗位需求,保证该课程的实践教学质量,课题组通过调研30余家就业单位微生物岗位实际,将课程原有实验教学内容整合为两大综合性实验项目,涵盖了食品微生物学全部基本实验技能。实践表明,两大综合性实验项目的开展可有效提高食品微生物学实验教学效果,使学生全面获得食品微生物学的基本实验技能,有助于提高学生的综合能力,实现学生与就业岗位的无缝对接。 相似文献

For a plant selection model with frequency-independent viabilities, fertilities and selfing rates, it is shown that apart from global fixation, for certain parameter combinations a protected polymorphism and facultative fixation (either allele may become fixed according to initial frequencies) may both occur. Facultative fixation requires different selling rates for the dominant and recessive type. Protection of the polymorphism requires resource allocation for male and female function. In this connection the problem of purely genetically caused population extinction is discussed.
For general frequency dependence and regular segregation, the chances for establishment of a completely recessive gene are compared to those of a completely dominant gene. It is proven that the process of establishment of the recessive gene, despite a fitness advantage, may be considerably endangered by drift effects if random mating prevails. The recessive gene may reach the same effectivity in establishment as a dominant gene, only if the recessive homozygote mates exclusively with its own type during the period of establishment. 相似文献

In this article, we systematically review Dr. Wu Lien-Teh's academic achievements and outstanding contributions in the prevention and control of the plague epidemic in northeast China and introduce the development of the earliest public health epidemic prevention system in China in order to commemorate the 140th anniversary of Dr. Wu Lien-Teh's birth. We hope that this article will provide insights into the effective prevention and control of emerging infectious diseases as well as the current worldwide pandemic of COVID-19, facilitating the improvement and development of public health systems in China and around the globe. 相似文献
