  Studies of genetic variation in human populations began inauspiciously.The first such study — of ABO blood group frequencies — was carried out by two Polish immunologists, Ludwik and Hanka Hirszfeld, at the end of the First World War.This work was notable for its broad coverage of the worlds populations, large sample sizes and scrupulous attention to anthropological details.Yet the Hirszfelds still ran into difficulties in publishing in The Lancet, the premier medical journal of the time.The editor could not see the relevance of their work, and so this seminal study of human genetic variation first appeared in an obscure anthropological journal.The relevance became abundantly clear when Felix Bernstein subsequently used the Hirszfelds data to demonstrate that the ABO blood-group frequencies were better explained by a single gene with three variants (alleles), and not — as prevailing wisdom then held — two genes each with two alleles.Happily, times have changed; diversity is now all the rage, and editors have become more appreciative of the importance of human genetic variation.

搞好储粮通风工作要有技巧、有目的、有针对性。根据储粮品种的不同、入库时间的差异在通风时机的选择上要因仓、因粮而异,选择通风的仓使用设备符合要求,被通风储粮要符合通风条件。为降低损耗、提高经济效益根据仓房储存条件可采用轴流风机通风、单管风机通风、离心风机通风或几种通风方式综合通风技术。使用综合、分阶段机械通风储粮方法,在这几年实践应用中取得了较好效果,采用该方法通风,作用迅速、可操作性强值得推广。
针对江苏省规模养殖废弃物超排,引起严重环境污染且资源大量浪费的突出问题,进行了猪粪、沼液替代化肥的初步研究.试验选择稻麦两熟制农田,研究了施用猪粪、沼液对稻田土壤理化性状及水稻产量的影响.试验结果表明,水稻收获时,100%猪粪处理的较常规施肥处理的耕层土壤容重显著降低(P<0.05),同时耕层土壤有机质、全氮、全磷和速效钾含量显著增加(P<0.05);而50%猪粪、50%沼液和100%沼液替代化肥
