An autonomous adaptive low-power instrument platform(AAL-PIP)chain of six stations has been newly established on East Antarctic Plateau along the 40°geomagnetic meridian,to investigate interhemispheric geomagnetically conjugate current systems,waves,and other space weather phenomena in Polar *** six stations,PG0 to PG5,which host low-power magnetometers(Fluxgate and Searchcoil),dual frequency GPS receivers,HF radio experiment,and run autonomously with solar power and two-way satellite communication,are designated at the geomagnetically conjugate(based on the International Geomagnetic Reference Field)locations of the West Greenland geomagnetic chain covering magnetic latitudes from 70°to 80°.We present the development,deployment,and operation of this chain,as well as the data collected by the chain and some preliminary scientific results showing evidence of interhemispheric asymmetries,which are important to better understand Solar Wind–Magnetosphere–Ionosphere(SWMI)coupling in Polar *** investigations focus on magnetic impulse(MI)events,traveling convection vortices(TCVs),and ultra-low frequency(ULF)waves in the coupled southern and northern hemispheres.

大学英语 2012年第9期 11-11页

作者： john bowman 天丰

英国一医疗保健协会称，如果人们在工作之余仍大量使用智能手机、平板电脑及手提电脑。其健康将面临威胁，他们也将成为“屏奴”。特许理疗协会说，人们使用这些设备时经常姿势不正，从而引发颈背疼痛。

A feasibility study to determine if minimally trained medical students can identify markers of chronic parasitic infection using bedside ultrasound in rural Tanzania

BACKGROUND: Parasitic infections pose a significant health risk in developing nations and are a major cause of morbidity and mortality worldwide. In the Republic of Tanzania, the CDC estimates that 51.5% of the population is infected with one or more intestinal parasites. If diagnosed early, the consequences of chronic parasitic infection can potentially be ***: Six first-year medical students were recruited to enroll patients in the study. They underwent ten hours of formal, hands-on, ultrasound which included basic cardiac, hepatobiliary, renal, pulmonary and FAST scan ultrasound. A World Health Organization protocol with published grading scales was adapted and used to assess for pathology in each patient's liver, bladder, kidneys, and ***: A total of 59 patients were enrolled in the study. Students reported a sensitivity of 96% and specificity of 100% for the presence of a dome shaped bladder, a sensitivity and specificity of 100% for bladder thickening, a sensitivity and specificity of 100% for portal hypertension and ascites. The sensitivity was 81% with a specificity of 100% for presence of portal vein distention. The sensitivity was 100% with a specificity of 90% for dilated ***: Ultrasound has shown a promise at helping to identify pathology in rural communities with limited resources such as Tanzania. Our data suggest that minimally trained first year medical students are able to perform basic ultrasound scans that can identify ultrasonographic markers of parasitic infections.

用RFLP标记分析甘蓝型油菜的遗传多样性

以甘蓝型油菜的２８个基因组探针和两种限制性内切酶对包括４６个中国品种、９个欧洲品种在内的５９个甘蓝型油菜品种（系）的ＲＦＬＰ标记进行了分析。在放射自显影胶片上，共检测到４１０条具多态性的分子杂交带，表明甘蓝型油菜中存在着极为丰富的遗传变异。聚类分析结果表明，在相似性为４５％的水平上，可把中国甘蓝型油菜划分为６组：胜利油菜组、跃进油菜组、中油８２１组、远缘种质组、优质油菜组和变异不详组。欧洲冬油菜与以上６组存在着较显著的遗传距离。主成分分析的结果与上述分组较为一致。以上结果表明，对于扩大中国甘蓝型油菜的遗传基础，欧洲冬油菜无疑是一个重要的种质资源。另一方面，用典型的中国甘蓝型油菜与欧洲冬油菜配制的杂交种，较易产生强大的杂种优势。从对已进行了染色体定位的６１条放射自显影带的分析看，无论是上述分组内，还是分组间，ＲＦＬＰ的相对差异均主要表现在Ａ基因组中。讨论了致使Ａ基因组遗传变异较大的可能因素。
