MoRGF1 was highly identical in amino acids with its homologs from other filamentous ascomycete fungi. The gene eletion mutants displayed slower growth and obviously reduced conidiation, although with no change in pathogenicity when compared with their wild type strain.

结果表明Mgg_11178.6编码一个假定的Rho族小G蛋白鸟苷酸交换因子(MoRGF1),与多种丝状子囊菌RhoGEF亲缘关系密切;基因敲除突变体表现为生长速度减慢,产孢量明显减少,但是致病力没有变化。

Gerber and Shiu (1998a) and Tsai and Willmot (2002) all consider the renewal equation for the expected discounted penalty function at ruin Ф and its decomposition in this risk process. In their proceeding, they assumed the twice continuous differentiability of Ф,Ф〓,Ф〓 as a premise but its proof isn't obvious.

Gerber and Landry(1998)及Tsai andWillmot(2002)考虑了此模型下的破产时罚金折现期望Ф所满足的更新方程及其分解后的因子Ф〓和Ф〓,但它们的推导过程都是在假定Ф,Ф〓,Ф〓连续且二次连续可微的前提条件下进行的,但实际上此前提假定的成立并非显然。

The team, who presented their results at a joint meeting of the American Association for Cancer Research and the International Association for the Study of Lung Cancer in Coronado, California, this week, are now investigating whether their putative cancer stem cells are more resistant than run-of-the-mill cancer cells to chemotherapy or radiation, as research on other putative stem cells has suggested.

本周,在加利福尼亚州科罗纳多举行的美国癌症研究学会和国际肺癌研究学会联合会议上,该小组公布了他们的研究结果。他们现在正在研究假定的肿瘤干细胞是否像其他假定干细胞上的研究显示的一样,比普通癌细胞更耐化疗及放疗。

Yet this strange supposition apparently underlies Professor Pigou's Theory of Unemployment14 and it is what all members of the orthodox school are tacitly assuming.

Based on the load transmission mechanism of space truss, and referenced theanalysis of test materials, a formula for calculating the bearing capacity of reinforcedconcrete compression strut is introduced. By using the theory of plastic hinge-line, anupper limit solution of bent bearing capacity for four-pile cap, which coincidesprecisely with the practical measurements, is obtained. By utilizing the reaction ofthe soil under cap and by basing on the method of plastic ultimate analysis, an upperlimit solution of punching shear bearing capacity for pile cap is acquired, which. coincides precisely with the practical measurements, and the formula is similar to thecode.A brief discuss on cooperative work of strip beam of foundation and single rankof piles is made. Separately considering the pile-cap and the pile-group, thencoupling their matrix of rigidity, the inner force of pile-cap is solved by the numericalmethod under some reasonable supposition. In comparison with other method, thecalculating results are exact, reliable and convenient in using. The method provides apowerful tQol fOr further analysis and research on this kind of structure.

本文以空间桁架传力机理为基础,结合试验资料分析,推导了钢筋混凝土等边三桩承台受冲切承载力计算公式;根据塑性铰线理论,导得了与试验结果吻合良好的四桩承台受弯承载力的上限解;利用承台底土反力分布,根据塑性极限分析方法,导得了桩基承台受冲切承载力的上限解,在此基础上,通过简化假定,得到与规范公式相类似的承台受冲切承载力实用公式,该公式能方便考虑台底土反力作用,与试验结果的吻合程度比规范公式好;简要讨论了桩基条形承台梁与单排桩的协同工作分析;在一些合理假定的基础上,将承台与群桩分开考虑,分别得到其刚度矩阵后进行耦合,通过数值方法求解承台内力,算例表明,该方法结果准确,使用方便,为该类结构的进一步分析研究及工程设计提供了强有力的工具。

The efforts that have been made to explain optical phenomena by means of the hypothesis of a medium having the same physical character as an elastic solid body led, in the first instance, to the understanding of a concrete具体的 example of a medium which can transmit transverse横向的 vibrations, and at a later stage to the definite conclusion that there is no luminiferous medium having the physical character assumed in the hypothesis.

为了解释光学现象,人们曾试图假定有一种具有与弹性固体相同的物理性质的介质。这种尝试的结果,最初曾使人们了解到一种能传输横向振动的介质,后来又使人们得到一个肯定的结论即具有上述假定所认为的那种物理性质的发光介质是没有的。
