论财务总监的事前监督与事后监督

财务总监制度的设立，是现代企业制度发展的要求，一般说来，财务总监的监督分为事前监督和事后监督。本文分析和探讨了财务总监的事前监督和事后监督机制，认为，应该将事前监督和事后监督机制配合运用，并辅之以切实可行的制衡手段，抑制经理人的机会主义行为，以保障所有者权益。

Changes in the glutathione thiol-disulfide status in wheat grain by foliar sulphur fertilization: consequences for the rheological properties of dough

Storage proteins and glutathione in wheat play an important role in gluten network formation and can be modified by supplementation of nitrogen (N) and sulphur (S) in wheat plants. The glutathione thiol-disulfide status and its relationship to the molecular weight distribution wheat polymeric protein and dough rheological properties have been examined after different foliar S fertilizations (S derived from micronized elemental S and NS, a mixture of N urea and elemental S) applied at the post-anthesis stage. Changes in levels of reduced glutathione (GSH), glutathione disulfide (GSSG), polymeric protein-glutathione mixed disulfide (PPSSG) were analysed by reversed phase high performance liquid chromatography, during grain development using the wheat cultivars, Soissons and Trémie. During the grain desiccation phase, S supplementation (i) increased the GSSG/GSH ratio by 23–25% (ii) induced PPSSG accumulation, and (iii) decreased the formation of SDS-unextractable polymeric protein (UPP) and its molecular mass distribution. However, simultaneous N and S supplementation results in: (i) a decrease in PPSSG formation by 20–30% and (ii) an increase of UPP by 7–18% by enhancing both the branching of the aggregated proteins and their molecular weight. The mixograph parameters show that all forms of endogenous glutathione are linked to dough weakening and are negatively correlated with dough mixing tolerance, dough strength and consistency, while UPP is positively correlated with dough strength and consistency. These findings indicate that S nutrition influences dynamics of the glutathione forms in the grain and results in modification the degree of polymerization of storage protein. Thus both the changes in the form of glutathione and protein polymerization influence the rheological properties of dough.

通过对黑龙江省东部山区10个林业局、427块标准地、1712株解析木的调查研究，得到了杨、桦林的树高、胸径和材积生长曲线，并编制了杨、桦林的抚育间伐控制图。     

造纸工业必须走林纸一体化与可持续发展道路

通过对我国造纸工业面临的现状和存在问题的调研、分析，并比较国内外造纸工业发展的现状，认为国内木材市场已经进入供不应求的紧缺阶段，而从国外进口木材，增加了企业的经营成本，又受市场的制约。所以企业通过自身营造集生态效益和经济效益为一体的原料林，是解决目前造纸工业瓶颈问题的现实而有效的途径。因此，造纸工业必须走林纸一体化与可持续发展的道路。     

宿根花卉的特点及其在园林中的配置

根据宿根花卉种类繁多、色彩丰富、生长稳定、抗逆性强的特点,其在园林中的配置,宜于建花坛、花境,也可群植,与背景树相结合,还可作地被植物代替草坪,也可建单类花卉园.     

南、北盘江流域（贵州部分）土地退化类型及机理

在对珠江上游南、北盘江流域（贵州部分）调查的基础上，分析了该流域土地退化成因，原生生态系统的脆弱性只是导致土地退化的一个方面。而人为活动才是土地退化的主要因素。根据土地退化的成因、结果，将珠江上游南、北盘江流域（贵州部分）土地退化划分为：土壤侵蚀、石漠化、土地贫瘠、土壤污染、土壤破坏五种类型，并提出了退化土地的管理及恢复措施。

红曲霉色素的提取

本实验确立了一种新的红曲霉色素提取方法:以红曲米为原料,乙醇为提取剂,得到的提取液再以正己烷提取分离。结果表明,此法所得的红曲霉色素是水溶性的,宜于用作食品添加剂。此外,还对影响提取的因素进行了探讨,并提供了最佳提取方案。     

Grouped, stacked rods and tapeta lucida in the retina of Japanese anchovy Engraulis japonicus

ABSTRACT: Morphology of the photoreceptor cells and tapetum of the Japanese anchovy Engraulis japonicus was studied by histologically and by chemical analysis. The Japanese anchovy has a duplex retina. The cones form parallel rows consisting of alternately placed long cones and bifid cones. Both types of cones are intimately associated and form triple units that are regularly spaced along the row of cones. The rods are grouped and stacked. This fish has a retinal tapetum lucidum composed of guanine and hypoxanthine. Three structures of the tapetum lucidum were recognized: platelet, diamond and rod types. Photomechanical changes include movements of the photoreceptor cells and the retinal tapetum. The retina of the Japanese anchovy is thought to be highly sensitive and well adapted to a dim light environment.
