Using electromagnetic treatment, an expression of effective nonlinear optical susceptibility χe [= χe^（2）＋ χe^（3） E] is obtained for Ⅲ-Ⅴ semiconducting crystals in an applied transverse dc magnetic fiem under off-resonant transition regime. The origin of nonlinear interaction lies in nonlinear polarization arising from the crystal properties such as piezoelectricity and electrostriction. Numerical estimates have been made by a representative n-InSb crystal at 77K duly irradiated by a pulsed 10.6-μm CO2 laser under off-resonant transition regime. Efforts are dedicated to optimizing doping level and externally applied dc magnetic field to achieve maximum χe^（2） and χ3^（3）. The results are found to be in good agreement with the available literature. The analysis shows that χe^（2） and χe^（3） can be significantly enhanced in doped Ⅲ-Ⅴ semiconductors by the proper selection of doping concentration and dc magnetic field, which confirms its potential as a candidate material for the fabrication of nonlinear optical devices.

"脂质假说"确定饱和脂肪酸(SFA)提高低密度脂蛋白胆固醇,从而增加代谢综合征(metS)的风险。本研究的目的是探讨亚慢性戒断高碳水化合物、高饱和脂肪(HCHF)对metS的影响,以及有害SFA饮食(C120月桂酸;C140肉豆蔻酸;C160棕榈酸;C180硬脂酸)对肝、白色脂肪组织(Wat)和粪便的影响。长时间饲喂HCHF饲料诱导metS大鼠作为人类metS模型。metS诱导大鼠在16周试验的最后4周变为基础日粮。分析靶组织和肝脏低密度脂蛋白受体(LDLr)SFA表达。通过分析SFA含量变化,戒断HCHF饲料后,WAT和肝脏中C160和C180含量减少。饲喂HCHF饲料时,粪便中C120含量极显著降低,而戒断后极显著增加(PmetS可造成肝脏和WAT中SFA的累积,降低SFA的排泄,减少肝脏LDLr表达,而戒断后显著逆转。本试验有助于更好地了解metS期间食物中SFA的代谢过程,有助于通过营养成分的调整改善潜在并发症。

位于印度西海岸附近的科依纳（Koyna）是众所周知的人造水库触发地震最显著的地方（Gupta，1992）。自从科依纳大坝建成之后斯瓦季萨加（Shivajisagar）湖蓄水以来的44年中，发生了震级m6．3的最大的触发地震（1967年12月10R）以及19个大于等于5级的地震。震级为4级左右的地震约170个，还有数千个更小的地震。最近的一次5级地震发生于2005年3月14R，在上一次5级地震发生了4年半之后（Satyanarayana et al，2005）。

本文对2001-2004年间,全印度2816例复治失败结核病患者的痰培养和药物敏感试验结果,在Chennai的结核病研究中心进行了回顾性分析。其中1498例(53%)被确诊为患有耐多药结核病(mDR-TB),671例(44.8%)至少耐一种二线抗结核药,分别为:490例(32.7%)耐乙硫异烟胺,245例(16.4%)耐氧氟沙星,169例(11.3%)耐卡那霉素;69例(4.6%)为广泛耐药结核病(XDR-TB)。尽管本结果是从高度选择的、不具代表性的患者人群中获得,但耐多药结核病患者中的二线抗结核药耐药率(包括XDR率)如此之高仍值得关注。因此,以高质量的DOTS服务来预防m/XDR-TB的产生,仍是目前的首要任务。此外,也需要尽快扩展在修改后的国家结核病控制规划(RNTCP)下的高质量的规划管理,以及更加规范规划之外对二线抗结核药的使用。
