云南新平哀牢山秋季夜间网捕鸟类的影响因素

2007-09-05-2007-11-05和2008-09-03-2008-11-07期间,在云南省新平县哀牢山金山丫口(23°57′N,101°30′E)对影响秋季夜间网捕鸟类组成因素进行了调查.主要利用温湿度表和定性观察对各因素进行判断.其研究结果表明,地理特点是影响夜间刚捕鸟类种类的主要因素:气象条件是影响夜间网捕鸟类种类和数量的重要因素.气象条件中的风向、风力、雾以及月相周期对夜间网捕鸟类数量和种类的影响极其显著(P<0.01).风向的影响比风力大,其中,在西南风大雾新月或者存西南风大雾残月期间,夜间网捕鸟类数量和种类最多:光也是夜间网捕鸟类的必要条件.然而,温湿度对夜间网捕鸟类数量和种类影响不显著.

Effect of laser heating temperature on coating characteristics of Stellite 6 deposited by cold spray

Laser-assisted cold spray (LCS) is a new coating and fabrication process which combines some advantages of CS: solid-state deposition, retain their initial composition and high build rate with the ability to deposit materials which are either difficult or impossible to deposit using cold spray alone. Stellite 6 powder is deposited on medium carbon steels by LCS using N 2 as carrier gas pressure. The topography, cross section thickness, structure of the coatings is examined by SEM, optical microscopy, EDX. The results show that thickness and fluctuation of coating are improved with increased deposition site temperature. Porosity of coating is affected by N 2 and deposition site temperature. In this paper, it presents optimal coating using N 2 at a pressure of 3 MPa and temperature of 450°C and deposition site temperature of 1100°C.

Investigating the use of elevators for high-rise building evacuation through computer simulation

This paper presents a description of a new agent based elevator sub-model developed as part of the buildingEXODUS software intended for both evacuation and circulation applications. A description of each component of the newly developed model is presented, including the elevator kinematics and associated pedestrian behaviour. The elevator model is then used to investigate a series of full building evacuation scenarios based on a hypothetical 50 floor building with four staircases and a population of 7,840 agents. The analysis explores the relative merits of using up to 32 elevators (arranged in four banks) and various egress strategies to evacuate the entire building population. Findings from the investigation suggest that the most efficient evacuation strategy utilises a combination of elevators and stairs to empty the building and clear the upper half of the building in minimum time. Combined stair elevator evacuation times have been shown to be as much as 50% faster than stair only evacuation times.

Spank performance tour [at Signals 07 arts festival]

Spank follows the journeys of two women as they reveal stories from private and public sources set apart by two centuries. It investigates notions of 'faction' and what is filtered out historically within a theme of female trauma and the body. [ABSTRACT BY THE AUTHOR]
