This paper compares legal systems for water management in France and China, with a focus on integrated water resources management and regarding in particular the formulation of policies and their implemen- tation. The research shows that China has committed itself to the efficient management of water resources through the development of various policy tools during the current period. This commitment, however, has often been interrupted and distorted by politics, resulting in the neglect of socioeconomic and environmental priorities. France has developed a legislative framework and practical instruments to apply integrated water resources manage- ment at the river basin level since the 1960s. This experience and the current implementation of the European Water Framework Directive brings elements that can contribute to Chinese society meeting its water challenges.

Genes encoding enzymes involved in biosynthesis of very long chain fatty acids were significantly up-regulatedduring early cotton fiber development. Two cDNAs, GhKCR1 and GhKCR2 encoding putative cotton 3-ketoacyl-CoAreductases that catalyze the second step in fatty acid elongation, were isolated from developing cotton fibers. GhKCR1and 2 contain open reading frames of 963 bp and 924 bp encoding proteins of 320 and 307 amino acid residues,respectively. Quantatitive RT-PCR analysis showed that both these genes were highly preferentially expressed duringthe cotton fiber elongation period with much lower levels recovered from roots, stems and leaves. GhKCR1 and 2showed 30%-32% identity to Saccharomyces cerevisiae Ybr159p at the deduced amino acid level. These cotton cDNAswere cloned and expressed in yeast haploid ybr159w? mutant that was deficient in 3-ketoacyl-CoA reductase ***-type growth rate was restored in ybr159w? cells that expressed either GhKCR1 or 2. Further analysis showed thatGhKCR1 and 2 were co-sedimented within the membranous pellet fraction after high-speed centrifugation, similar to theyeast endoplasmic reticulum marker ScKar2p. Both GhKCR(s) showed NADPH-dependent 3-ketoacyl-CoA reductaseactivity in an in vitro assay system using palmitoyl-CoA and malonyl-CoA as substrates. Our results suggest thatGhKCR1 and 2 are functional orthologues of ScYbr159p.

The effects of melt composition,temperature and pressure on the solubility of fluorite(CaF2),i.e.,fluorine concentration in silicate melts in equilibrium with fluorite,are summarized in this *** authors present a statistic study based on experimental data in literature and propose a predictive model to estimate F concentration in melt at the saturation of fluorite(CFin melt^Fl-sat).The modeling indicates that the compositional effect of melt cations on the variation in can be expressed quantitatively as one parameter FSI(fluorite saturation index):FSI=(3Al^NM+Fe^2++6Mg+Ca+1.5Na-K)/(Si+Ti+Al^NF+Fe^3+),in which all cations are in mole,and Al^NF and Al^NM are A1 as network-forming and network-modifying cations,*** dependence of CFin melt^Fl-sat on FSI is regressed as:CFin melt^Fl-sat=1.130-2.014·exp(1000/T)+2.747·exp(P/T)+0.111·CmeltH2O+17.641·FSI,in which T is temperature in Kelvin,P is pressure in MPa,CmeltH2O is melt H2O content in wt.%,and CFin melt^Fl-sat is in wt.%(normalized to anhydrous basis).The reference dataset used to establish the expression for conditions within 540-1010℃,50-500 MPa,0-7 wt.%melt H2O content,0.4 to 1.7 for A/CNK,0.3 wt.%-7.0 wt.%for CFin melt^*** discrepancy of CFin melt^Fl-sat between calculated and measured values is less than±0.62 wt.%with a confidence interval of 95%.The expression of FSI and its effect on CFin melt^Fl-sat indicate that fluorine incorporation in silicate melts is largely controlled by bonding with network-modifying cations,favorably with Mg,Al^NM,Na,Ca and Fe^2+in a decreasing *** proposed model for predicting CFin melt^Fl-sat is also supported by our new experiments saturated with magmatic fluorite performed at 100-200 MPa and 800-900℃.The modeling of magma fractional crystallization emphasizes that the saturation of fluorite is dependent on both the compositions of primary magmas and their initial F contents.

法国正在致力于发展高超声速吸气式推进系统和推阻平衡预测能力所需要的技术。通过地面试验研究完成其大部分技术开发,目前正在对燃烧室进行攻关研究,以确保燃烧效率和结构热力强度满足要求。另一方面,为了掌握推阻平衡技术,必须进行飞行试验。因此,MBDA和ONERA正在推进LEA飞行试验计划。此计划始于2003年1月,准备在后续几年内完成马赫数4到8的若干次飞行试验。在2009年中期,通过关键设计评估完成了LEA飞行器推进系统的验证。将确定在2011年春季通过一系列自由射流试验验证飞行器的推阻平衡。此外,系统地开展了可重复使用运载器和高速民用飞行器的可行性和可实现的工作性能研究。
