2018年全球生物技术/转基因作物商业化发展态势

<正>1前言生物技术可以用于开发更耐旱与更有营养的作物品种,从而保护自然资源与人类健康。根据具体情况对每种生物技术/转基因作物进行具体评估,获准上市的商业化产品已经通过严格的科学审查。生物技术/转基因作物应视为一种提高作物产量的工具,其在食品安全方面无不良记录,为粮食产量得不到保证的农民带来更多收入。通过应用生物技术/转基因作物获得的这些经济效益、健康改善和社会效益应向全球社区公布,使农民和消费者能够

海豹也需要尊重

每年春天．成千上万只琴海豹和帽海豹从北极迁游到加拿大东海岸,在圣劳伦斯湾清新纯净的浮冰上繁殖后代。那时,万里冰原变成了海豹的育婴园。雪白、毛绒绒的小海豹沐浴在初春的阳光下,依偎在妈妈的身旁吸吮乳汁。刚出生的小海豹不会游泳,为了抗拒严寒,它们必须大量地吃极富脂肪的奶水,以每天增长两公斤的速度成长。春末夏初,冰面融化,     

Multi-locus association study of schizophrenia susceptibility genes with a posterior probability method

Schizophrenia is a serious neuropsychiatric illness affecting about 1% of the world’s population. Family, twin and adoption studies have demonstrated that 65%―85% of the susceptibility to schizophrenia can be attributed to genes. On the basis of genetic model-ing of epidemiological data and recent results of a number of whole-genome screens for susceptibility genes, schizophrenia has been considered a complex disorder. A number of genes with small to moderate effects are involved in combinat…     

A Computational Model of Soil Adhesion and Resistance for a Non-smooth Bulldozing Plate

1IntroductionAdhesive forces exist between soil and the surfacesof soil-engaging components[1,2].Soil adhesion increasesthe running resistance and energy consumption,andaffects the operating quality.Soil adhesion also reducesthe working productivity of terrain machines,even worseit makes terrain machines fail to run.Reducing theadhesive force of the soil-engaging machines will have aprofound influence for cultivation.Through theinvestigation of soil animals,we have found that soilanimals poss…
