Parasitoid wasp communities of the canopy of temperate forests are still largely unexplored. Very little is known about the community composition ofparasitoids between canopy and understory and how much of this difference is related to forest structure or parasitoid biological strategies. In this study we investigated upon the difference in the community composition of the parasitic wasps Ichneumonidae between canopy and understory in a lowland temperate forest in northern Italy. We used general linear models to test whether parasitic strategy modifies species vertical stratification and the effect of forest structure. We also tested differences in β-diversity between canopy and understory traps and over time within single forest layers. We found that stand basal area was positively related to species richness, suggesting that the presence of mature trees can influence local wasp diversity, providing a higher number of microhabitats and hosts. The ichneumonid community of the canopy was different from that of the understory, and theβ-diversity analysis showed higher values for the canopy, due to a higher degree of species turnover between traps. In our analyses, the vertical stratification was different between groups of ichneumonids sharing different parasitic strategies. Idiobiont parasitoids of weakly or deeply concealed hosts were more diverse in the understory than in the canopy while parasitoids of spiders were equally distributed between the two layers. Even though the ichneumonid community was not particularly species-rich in the canopy of the temperate forests, the extension of sampling to that habitat significantly increased the number of species recorded.

功率转换器的功率密度越来越高,发热问题越来越严重,这种功率转换器的设计对现代大功率半导体技术提出了新的挑战;因而,热问题的优化设计和核实变得比大功率器件的电模型更加重要,本文提出一种新的PSPICE模型,可以利用它计算MOSFET芯片在瞬变过程中的温度。其中的热阻可以从制造商提供的产品使用说明书得到。本文介绍的模型提供发热和电气参数之间的动态关系。它建立了与许可的热环境的关系,例如,栅极驱动电路、负载、以及散热器的分析与优化设计。利用这个模型可以改善散热器的设计。由于决定功率损耗的参数是分布在一定范围内,受生产制造的影响很大,因而散热器的设计往往由于无法预先知道功率损耗而无法进行。

Metastatic tumors of the gastrointestinal tract are rare. We describe a case of gastric metastasis due to primary lung cancer, revealed by an upper gastrointestinal endoscopy （UGIE）. Haematogenous metastases to the stomach are a rare event. To our knowledge, only 55 cases have been described in the international literature. In these patients, the prognosis is very poor. We report herein a case of gastric metastasis by lung small cell carcinoma, with a review of the literature about this rare entity.
