The capacity of ground support components which have been affected by corrosion is reduced and may ultimately lead to dynamic failure of the component and the strata. In order to maintain an effective,long-term ground support system, significant campaigns of rehabilitation are often required in corrosion affected areas which also expose the workers to hazardous conditions. The most common corrosion protection for steel ground support utilises sacrificial systems such as galvanising. Galvanising has previously been proven to be susceptible to some corrosion processes. Stainless steel is the most effective in resistance to corrosion, but can be cost prohibitive, and its mechanical properties often make it unsuited to use in ground support components. Providing an outer protective plastic coating to bolts has proven to be an effective means of protecting the inner steel bar from corrosion. However, these support systems tend to be susceptible to coating damage, and require post cement grouting to provide full encapsulation. In comparison to a standard bolt/resin system, they can be slow to install and *** systems have also been shown to reduce overall load transfer performance of the bolting system. In order to provide a higher level of corrosion protection whilst maintaining current installation practices and bolting cycle times, Minova has developed the Enduro^(TM)steel ground support range. The Enduro^(TM) range consists of standard Minova steel ground support components which have been treated with a unique coating process. The Enduro^(TM)coating has been tested in the harshest of conditions, in laboratory controlled conditions and in underground trials. It has been proven to effectively resist or completely eliminate the formation of corrosion, even in the most aggressive environments. This paper explains the process and provides the details of the laboratory and underground corrosion performance testing carried out on Enduro^(TM)ground support product

An INDEHISCENT-Controlled Auxin Response Specifies the Separation Layer in Early Arabidopsis Fruit

引用

Molecular Plant 2016年第6期9卷 857-869页

Seed dispersal is an important moment in the life cycle of a plant species. In Arabidopsis thaliana, it is dependent on transcription factor INDEHISCENT （IND）-mediated specification of a separation layer in the dehiscence zone found in the margin between the valves （carpel walls） and the central replum of the developing fruit. It was proposed that IND specifies the separation layer by inducing a local auxin minimum at late stages of fruit development. Here we show that morphological differences between the ind mutant and wild-type fruit already arise at early stages of fruit development, coinciding with strong IND expression in the valve margin. We show that IND-reduced PIN-FORMED3 （PIN3） auxin efflux carrier abundance leads to an increased auxin response in the valve margin during early fruit develop- ment, and that the concomitant cell divisions that form the dehiscence zone are lacking in ind mutant fruit. Moreover, IND promoter-driven ectopic expression of the AGC kinases PINOID （PID） and WAG2 induced indehiscence by expelling auxin from the valve margin at stages 14-16 of fruit development through increased PIN3 abundance. Our results show that IND, besides its role at late stages of Arabi- dopsis fruit development, functions at early stages to facilitate the auxin-triggered cell divisions that form the dehiscence zone.

双线性滞迟模型可以描述干摩擦的非线性特性,但用它的精确介来求干摩擦阻尼系统的响应就很困难和麻烦。鉴于工程中一般干摩擦阻尼系统的位移振幅基本上是正弦的,非线性干摩擦力可以用它的基频成份来近似。这个基频成份的阻力幅值和方向是与摩擦面之间的相对位移大小密切有关,它的方向一般不像传统的假定那样,与相对速度差180°。只有在很大的相对位移时,它的方向才符合传统的假定。本文用这个近似阻力估算了干摩擦隔振系统的非线性响应,基本上符合实验响应曲线。

本文研究了澳大利亚高等法院最近对《1968年版权法》进行解释的方法,尤其是在这种解释中立法背景的角色和效用。毫无疑问,版权法很复杂。并且自1968年法令在澳大利亚生效以来,它的适用性和用语日益复杂。法律需要在瞬息万变的环境中运作,并且在该环境中存在许多利益分歧。同时,近年来,法庭对法律解释的处理方式发生了变化,并且重新关注了语境因素。尽管这项司法命令要求在解释法律时考虑语境,但其影响下仍然存在许多问题。首先,在制定法律的过程中有时会不明真相,而且缺乏法律背后原则的确定性。那么,法规的语境、目的或对象可能就无法确定。立法涉及多个阶段,每个阶段都有可能导致歪曲或者模糊法律目的和语境的结果,这些将在本文的第一部分中进行讨论。在第二部分中,将涉及澳大利亚高等法院最近在确定版权法中的语境时所采用的方法。最后,将提出改革建议,以改善语境的可用性来协助法院进行法律解释。
