1Field Relationships,Geochemistry,Zircon Ages and Evolution of a Late Archaean to Palaeoproterozoic Lower Crustal Section in the Hengshan Terrain of Northern China显示文摘The Hengshan complex forms part of the central zone of the North China Craton and consists predominantly of ductilely-deformed late Archaean to Palaeoproterozoic high-grade, partly migmatitic, granitoid orthogneisses, intruded by mafic dykes of gabbroic composition. Many highly strained rocks were previously misinterpreted as supracrustal sequences and represent mylonitized granitoids and sheared dykes. Our single zircon dating documents magmatic granitoid emplacement ages between 2.52 Ga and 2.48 Ga, with rare occurrences of 2.7 Ga gneisses, possibly reflecting an older basement. A few granitic gneisses have emplacement ages between 2.35 and 2.1 Ga and show the same structural features as the older rocks, indicating that the main deformation occurred after ~2.1 Ga. Intrusion of gabbroic dykes occurred at~1920 Ma, and all Hengshan rocks underwent granulite-facies metamorphism at 1.88-1.85 Ga, followed by retrogression, shearing and uplift.We interpret the Hengshan and adjacent Fuping granitoid gneisses as the lower, plutonic, part of a late Archaean to early Palaeoproterozoic Japan-type magmatic arc, with the upper, volcanic part represented by the nearby Wutai complex. Components of this arc may have evolved at a continental margin as indicated by the 2.7 Ga zircons. Major deformation and HP North China Craton collided to form the Trans-North China orogen. Shear zones in the Hengshan are interpreted as major lower crustal discontinuities post-dating the peak of HP metamorphism, and we suggest that they formed during orogenic collapse and uplift of the Hengshan complex in the late Palaeoproterozoic (<1.85 Ga).A.

4卫生政策分析:概念和方法的思考与挑战显示文摘许多专家学者就卫生政策分析开展了大量研究,但很少关注如何进行政策分析以及需要什么样的研究设计、理论和方法。本文着眼于卫生政策分析的环境以及面临的挑战,借鉴中低收入国家中一些卫生政策分析的框架、理论、方法和设计,列举了最近的研究案例,并探讨了案例研究的意义以及研究设计的必要性,发现卫生政策研究者的角色、反思和定位在研究过程中非常重要。最后从理论、方法学和研究人员的反思等角度提出了促进卫生政策分析的建议。Gill Walt Jeremy Shiffman Helen Schneider Susan F Murray Ruairi Brugha Lucy Gilson 2012中国卫生政策研究2012,5,12:3
5四基色投影显示显示文摘我们采用多芯片HTPS屏结构,已开发出一种四基色前投式投影样机。这种投影机建立在对一种现行高端品牌产品的光学平台进行改进的基础之上。在KESHETTM芯片中,用ColorPeakTM算法,把标准720p输入信号转换成所需要的多基色输入信号,结果使色域和亮度都有了显著的提高。Shmuel Roth Walt Caldwell 刘秀 2005现代显示2005,,12:2
6Understanding of chemoprophylaxis and concordance in inflammatory bowel disease显示文摘AIM:To assess patients' understanding for the reasons for taking 5-aminosalicylic acid or ursodeoxycholic acid as chemoprophylaxis against colorectal carcinoma associated with in? ammatory bowel disease (IBD). METHODS: A questionnaire-based study using a 5 point opinion scale was performed. One hundred and ninety-two patients with colitis only and 74 patients with primary sclerosing cholangitis and IBD were invited to take part. RESULTS: Overall response rate was 58%. Sixtyfour percent of patients claimed full concordance with chemoprophylaxis for maintenance of remission. Eightyfour percent of patients considered daily concordance during remission to be very important. Seventy-five percent stated they understood the reasons for taking the drugs. However, only 50% of the patients were aware of any link of their condition to bowel cancer. Seventy-nine percent of patients felt their concordance and understanding would be improved if they were informed of the chemoprophylactic potential of the medication.Adam Low Melanie Love Robert Walt Katherine Kane Bertus Eksteen Jason Goh 2010World Journal of Gastroenterology2010,16,5:2
