We are pleased to present this special issue of Cur- rent Zoology entitled ＂Behaviour, Ecology and Evolu- tion of Fishes＂. The goal of this special issue is to showcase some of the recent developments in research occurring at the interface of fish behavioral ecology and evolution and to stimulate further research in this fascinating field. Most, but not all, of the papers fall under specific themes we identified in the call for submissions for this special issue. The issue features four review articles and fourteen original articles. The first review article, bv I. C6t6 and S. Green. describes

Trends in Extremes of Surface Humidity, Temperature, and Summertime Heat Stress in China

引用

Advances in Atmospheric Sciences 2001年第5期18卷 742-751页

作者： julian X.L. Wang and Dian j. Gaffen NOAA/ Air Resources Laboratory, Silver Spring, MD, 20910, USA NOAA/ Air Resources Laboratory Silver Spring USA

In the past half century, the mean summertime temperature in China has increased, with nights warm- ing more than days. Using surface station observations, we show that the frequency of extreme heat-stress events in China, caused by extremely hot and humid days as well as by heatwaves lasting for a few days, has increased over the period from 1951 to 1994 When humidity is high, hot weather can cause heat stress in humans. The increased heatrstress trend may pose a public health problem

Tetrahedral amorphous carbon coatings have the potential to significantly reduce friction and wear between sliding ***,we provide atomistic insights into the evolution of the sliding interface between naked and hydrogen-passivated ta-C sliding partners under dry and lubricated *** reactive classical atomistic simulations we show that sliding induces a sp3 to sp2 rehybridization and that the shear resistance is reduced by hydrogen-passivation and hexadecane-lubrication-despite our finding that nanoscale hexadecane layers are not always able to separate and protect ta-C counter surfaces during *** asperities deform,carbon atoms within the hexadecane lubricant bind to the ta-C sliding partners resulting in degradation of the hexadecane molecules and in increased material intermixing at the sliding *** atoms from the passivation layer and from the hexadecane chains continue to be mixed within a sp2 rich sliding interface eventually generating a tribo-layer that resembles an a-C:H type of *** separation of the sliding partners,the tribo-couple splits within the newly formed sp2 rich a-C:H mixed layer with significant material transfer across the sliding *** leaves behind a-C:H coated ta-C surfaces with dangling C bonds,linear C chains and hydrocarbon fragments.
