  Herein, we reported the synthesis of 16 novel steroidal thiosemicarbazone derivatives via the condensation of steroidal ketones and substituted thiosemicarbazides under solvent-free conditions using microwave irradiation. The yields obtained are in the range of 84–96% using microwave method and 46–62% using conventional method. All the synthesized compounds (7a–p) have been characterized by 1H NMR

  在本文中，我们报道了在无溶剂条件下使用微波辐射通过甾族酮和取代的硫代氨基脲的缩合反应合成16种新型甾族硫代氨基脲衍生物。使用微波方法获得的产率在84–96％的范围内，而使用常规方法获得的产率在46–62％的范围内。所有合成的化合物（7a – p）均已通过1 H NMR，ESI-MS，IR和元素分析进行​​了表征。对所有系列化合物（7a–p）的抗细菌活性进行了评估，并将结果与​​标准药物阿莫西林进行了比较。该系列中的一些化合物，例如7c，7o和7p与阿莫西林等效于铜绿假单胞菌。化合物7h对金黄色葡萄球菌和枯草芽孢杆菌的抑制作用也优于阿莫西林。

• Spatial Variability of Different Fractions of Particulate Matter within an Urban Environment and between Urban and Rural Sites

  The spatial variability of different fractions of particulate matter (PM) was investigated in the city of Basel, Switzerland, based on measurements performed throughout 1997 with a mobile monitoring station at six sites and permanently recorded measurements from a fixed site. Additionally, PM10 measurements from the following year, which were concurrently recorded at two urban and two rural sites, were compared. Generally, the spatial variability of PM4, PM10, and total suspended particulates (TSP) within this Swiss urban environment (area = 36 km2) was rather limited. With the exception of one site in a street canyon next to a traffic light, traffic density had only a weak tendency to increase the levels of PM. Mean PM10 concentration at six sites with different traffic densities was in the range of less than +/- 10% of the mean urban PM10 level. However, comparing the mean PM levels on workdays to that on weekends indicated that the impact of human activities, including traffic, on ambient PM levels may be considerable. Differences in the daily PM10 concentrations between urban and more elevated rural sites were strongly influenced by the stability of the atmosphere. In summer, when no persistent surface inversions exist, differences between urban and rural sites were rather small. It can therefore be concluded that spatial variability of annual mean PM concentration between urban and rural sites in the Basel area may more likely be caused by varying altitude than by distance to the city center.
