地震预测预报的难度大,但并非了无痕迹或不可知,我国每次较大的地震都有案例总结。统计表明,近40 年来,有77 次地震在发生前均有中期、短期甚至临震预测,不能因为汶川地震预测的失败,就全面抹杀中国的地震预报成绩,即我国的地震预测成绩是应予肯定的,汶川地震也并非是无前兆的“怪震”。

Cogeneration cycle is an efficient mean to recover the waste heat from the flue gases coming out of gas turbine. With the help of computer simulation, design parameters may be selected for the best performance of cogeneration cycle. In the present work a program is executed in software EES on the basis of mathematical modelling described in paper to study cogeneration cycle performance for different parameters. Results obtained are compared with the results available in literature and are found in good agreement with them. Real gas and water properties are inbuilt in the software. Results show that enthalpy of air entering the combustion chamber is higher than that of the flue gases at combustion chamber outlet. For different operative conditions, energy and exergy efficiencies follow similar trends; although, exergy efficiency values are always lower than the corresponding energy efficiency ones. From the results it is found that turbine outlet temperature (TIT) of 524°C is uniquely suited to efficient cogeneration cycle because it enables the transfer of heat from exhaust gas to the steam cycle to take place over a minimal temperature difference. This temperature range results in the maximum thermodynamic availability while operating with highest temperature and highest efficiency cogeneration cycle. Effect of cycle pressure ratio (CR), inlet air temperature (IAT) and water pressure at heat recovery steam generator (HRSG) inlet on the 30 MW cogeneration cycle is also studied.

Kernel texture (grain hardness) is a fundamental and determining factor related to wheat ( spp.) milling, baking and flour utilization. There are three kernel texture classes in wheat: soft and hard hexaploid ( ), and very hard durum ( subsp. ). The genetic basis for these three classes lies with the Puroindoline genes. Phenotypically, the easiest means of quantifying kernel texture is with the Single Kernel Characterization System (SKCS), although other means are valid and can provide fundamental material properties. Typical SKCS values for soft wheat would be around 25 and for durum wheat≥80. Soft kernel durum wheat was created via homeologous recombination using the mutation, which facilitated the transfer of ca. 28 Mbp of 5DS that replaced ca. 21 Mbp of 5BS. The 5DS translocation contained a complete and intact locus and both puroindoline genes. Expression of the puroindoline genes in durum grain resulted in kernel texture and flour milling characteristics nearly identical to that of soft wheat, with high yields of break and straight-grade flours, which had small particle size and low starch damage. Dough water absorption was markedly reduced compared to durum flour and semolina. Dough was essentially unchanged and reflected the inherent gluten properties of the durum background. Pasta quality was essentially equal-to-or-better than pasta made from semolina. Agronomically, soft durum germplasm showed good potential with moderate grain yield and resistance to a number of fungal pathogens and insects. Future breeding efforts will no doubt further improve the quality and competitiveness of soft durum cultivars.

组织工程模板中的生物相容性途径 Perspective

组织工程通过系统结合分子信号和力学信号对特定靶细胞进行有意可控刺激以组建新的组织,通常需要借助由生物材料构建的结构传递这些信号,并对生成的组织块塑形。这些结构之前被称为支架,如今被更准确地命名为模板,其规范却难以定义,主要因为该规范必须涉及为细胞组建新组织提供适宜的微环境,以及细胞与模板材料的相互作用符合构建新型可存活组织的需求。这些特点统称为生物相容性。然而,传统生物相容性的理论和公认机制(大多通过可移植的医学装置进行实验得出)不足以解释在组织工程过程中的现象。本文作者近期在特定的基于材料、生物学的途径方面重新定义了生物相容性。本文以上述途径为前提讨论了组织工程生物相容性的机制。
