1Numerical modelling of structural controls on fluid flow and mineralization显示文摘这份报纸论述在热水的矿化作用上集中于结构的控制的一套数字模型的结果。我们首先为如此的控制给控制在结构上的矿石形成和背景理论和机制的自然现象的概述。我们然后提供数字模型通过比较验证了, Cu 静脉结构在 Shilu 铜沉积物附近观察了的一组简单 2D 的结果(Yangchun,广东省,中国) 并且最后数字建模在北方 Queensland (澳大利亚) 用于 Hodgkinson 省的 3D 的案例研究。二条建模途径,分离变丑建模和连续统联合了变丑和液体流动建模,被包含。2D 导出模型的模式与从 Shilu 铜存款的 Cu 静脉结构显著地一致,并且证明两条建模途径能写实地模仿机械行为砍并且膨胀破裂。联合变丑和液体流动建模的连续统显示 Shilu 存款附近的 Cu 静脉的那个模式是结果砍紧张本地化,膨胀的发展并且液体集中进膨胀破裂分割。3D 案例研究模型(与联合的变丑和液体流动) 在 Hodgkinson 上,省产生了很多个潜在的金矿化作用目标。J.Robinson P.M.Schaubs 2011Geoscience Frontiers2011,2,3:10

4运载火箭用的先进复合材料结构显示文摘先进复合材料按传统观念不能用于一次性运载火箭的主结构。固然,减轻重量对于运载火箭是很重要的,但是复合材料的优良性能还不具备足够的吸引力,还不能足以证明已作过的研制件和合格品的必要成本能替代现有金属材料的结构设计。现有的运载任务正促使运载火箭向其运载能力的极限推进,特别强调需要研制大推力的大型运载火箭,以便在合理的成本条件下保证进入太空。麦克唐纳·道格拉斯空间系统公司正积极为先进运载系统研完重量轻、成本低的复合材料结构,为现有的一次性使用的运载火箭,如德尔它、大力神、宇宙神等运载火箭,提供可行的工艺方案。Michael J.Robinson 陈文光 1991国外导弹与航天运载器1991,,10:1
5植物病毒病与生物技术的应用显示文摘尽管基于分子生物学的新技术有助于植物病毒性疾病的检测和控制,但是哪里生长作物,这类疾病就会给哪里造成损失。单克隆抗体技术和核酸杂交技术为鉴别病毒提供了有效的新方法。而遗传工程正在创造抗病毒病的崭新性质,这些性质可以被整合到现存农作物的变种中。David J.Robinson 孟征 1989科学对社会的影响1989,38,2:0
6Perturbations of the ileal mycobiota by necrotic enteritis in broiler chickens显示文摘Background:Intestinal microbiota is critical for maintaining animal health and homeostasis.However,involvement of the fungal community,also known as the mycobiota,in animal health and disease is poorly understood.This study was aimed to examine the association between the intestinal mycobiota and the severity of necrotic enteritis(NE),an economically significant poultry disease.Methods:A total of 90 day-of-hatch Cobb broilers were infected with Eimeria maxima on d 10,followed by an oral challenge with C.perfringens on d 14 to induce NE,while another 10 broilers were served as mock-infected controls.On d 17,the lesions in the jejunum were scored,and the ileal digesta were subjected to DNA isolation and real-time PCR quantification of total bacterial and fungi populations.Internal transcribed spacer 2(ITS2)amplicon sequencing was also performed to profile the ileal mycobiota composition.Changes in the ileal mycobiota in response to NE were investigated.Spearman correlation analysis was further conducted to identify the correlations between relative abundances of individual ileal fungi and the severity of NE.Results:While the total bacterial population in the ileum was increased by 2-to 3-fold in NE chickens,the total fungal population was progressively declined in more exacerbated NE,with the most severely infected chickens showing a nearly 50-fold reduction relative to mock-infected controls.Richness of the ileal mycobiota also tended to reduce in chickens with NE(P=0.06).Compositionally,among 30 most abundant fungal amplicon sequence variants(ASVs),11 were diminished and 7 were enriched(P<0.05),while 12 remained largely unchanged in NEafflicted chickens(P>0.05).Multiple Wallemia and Aspergillus species were markedly diminished in NE(P<0.05)and also showed a significant negative correlation with NE severity(P<0.05).Conclusions:Dysbiosis of the ileal mycobiota is induced evidently by NE and the extent of the dysbiosis is positively correlated with disease severity.These findings suggest a possible role of the intestinal mycobiota in NE pathogenesis and highlight the mycobiota as a new potential target for NE mitigation in poultry.Qing Yang Jing Liu Kelsy J.Robinson Melanie A.Whitmore Sydney N.Stewart Guolong Zhang 2022Journal of Animal Science and Biotechnology2022,13,2:0
7一种哈利迪构架里的词汇教学方法显示文摘引言:句法对词汇直至最近,词汇教学在语言教学中一直不是一个优先考虑的领域,因此,对于如何组织和规定一个课程的词汇内容至今没有多少争论。讨论一般只局限于词汇表的作用以及所教具体词项的出现率(见Meara,1980)。基于成分的句法之传统特征(句子结构、名词、动词等)在决定课程设计单位的基础方面一直受到较大重视。这无疑反映了语言理论的普遍构架。这种构架来自布龙菲尔德,并且对于乔姆斯基语言学也至关重要。Twaddel(1973)说到,“Peter J.Robinson 靳林 1990外语教学理论与实践1990,,1:0
