The crystallization temperature and pressure of clinopyroxene phenocrysts from the ankaramite and basalt were estimated on the basis of the clinopyroxene-melt equilibrium principle: 1345～1366℃ and 1.75～2.05Gpa for ankaramite, with average geothermal gradient of 20-24℃/km, suggesting anomalous heat or geothermal gradient in this region may be one of the key reasons to produce the porphyry copper deposits in the region. In contrast, those in the basalts fomed under a relatively low crystallization temperature (1129～1191℃), and the pressure (1.19～1.60Gpa) and depth (39～53km), suggesting that the basalt formed under a condition of lower temperature and pressure.

At the same time, the New York State Department of Health aired a separate, simultaneous statewide television-based antitobacco media campaign that also targeted New York City, with advertisements featuring graphic images of the effects of smoking and highlighting the effects of secondhand smoke on children. From January through December 2006, New York City adult smokers were exposed to nearly 11,000 GRPs as a result of both campaigns combined, equating to the average viewer in NYC seeing an advertisement approximately 110 times during the year.

Using RAPD markers techonolgy analysed the genetic structure of populations and built up the reaction system of SSR markers of Aristida pennata, at the same time, analysed the genetic structure based on SSR markers techonolgy. The research results are as follow:(1) 11 amplifiction random primers were used to detecte 125 loci in 76 samples. The total proportion of polymorphic loci of. Aristida pennata is 96.8%, the average proportion of polymorphic loci of Aristida pennata is 45.3%. The analyses of Shannon diversity index (1,0.5151) and Nei gene diversity index(h, 0.3471) indicate that the gene variation is rich in subpopulations.

However, in designing the beamless slabs with equivalent frame method, the stress is an average values along the depth of section, which varies with the normal service state. Compared with the results by finite element method, the results gained by equivalent frame method cannot satisfy the requirement under the normal service state. Therefore, the tendons of beamless slabs should be designed and arranged based on the results of FEM taking account into vertical load and prestressed load.

本文通过分析，认为采用等代框架法进行无梁板设计时，其内力是基于截面平均的结果，在正常使用状态与实际受力状态有很大的不同，通过对比等代框架法和有限元计算的正常使用极限状态应力可知，按等代框架法设计的预应力布置并不能保证其正常使用极限状态的要求，据此提出了应根据无梁板在竖向荷载和预应力共同作用下弹性有限元分析结果进行预应力筋布置的建议。

This relationship between body composition and cognitive function in old age is still unclear, the authors write. To address this question, the researchers used data from the Chicago Health and Aging Project, a longitudinal study conducted from 1993 to 2003 in a biracial community on the south side of Chicago, with an average of 6.4 years of follow-up. The cohort included 3885 community-dwelling adults aged 65 years and older who participated in at least 2 assessments.
