The growing public health concern of sports concussion: The new psychology practice frontier.

With youth participation in sports at an all-time high, youths have become more vulnerable to the silent epidemic of concussion. Psychologists should become aware of the alarming frequency of mild concussion and the subtle effects of concussion, which often go unnoticed or result in misdiagnosis. This article provides a basic survey of the research and literature on this topic, a simplified knowledge base for understanding updated assessment and management techniques, and a discussion of the important role psychologists can play in educating the public and their patients. Practitioners can become more aware of this developing practice opportunity. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Durability of polymeric glazing materials for solar applications

The economic viability of solar collector systems for domestic hot water (DHW) generation is strongly linked to the cost of such systems. Installation and hardware costs must be reduced by 50% to allow significant market penetration. An attractive approach to cost reduction is to replace glass and metal parts with less expensive, lighter weight polymeric components. Weight reduction decreases the cost of shipping, handling, and installation. The use of polymeric materials also allows the benefits and cost savings associated with well established manufacturing processes, along with savings associated with improved fastening, reduced part count, and overall assembly refinements. A key challenge is to maintain adequate system performance and assure requisite durability for extended lifetimes. Results of preliminary and ongoing screening tests for a large number of candidate polymeric glazing materials are presented. Based on these results, two specific glazings with moderate and poor weathering stability are selected to demonstrate how a service lifetime methodology can be applied to accurately predict the optical performance of these materials during in-service use. A summary is given for data obtained by outdoor exposure and indoor testing of polyvinyl chloride (PVC) and high temperature modified polycarbonate copolymer (coPC) materials, and an initial risk analysis is given for the two materials. Screening tests and analyses for service lifetime prediction are discussed. A methodology that provides a way to derive correlations between degradation experienced by materials exposed to controlled accelerated laboratory exposure conditions and materials exposed to in-service conditions is given, and a validation is presented for the methodology based upon durability test results for PVC and coPC.     

劈刀和肋环夹持工况对超声键合换能系统电学特性的影响

通过实验分析了肋环夹持松紧度和劈刀存在两个因素对超声键合换能系统电学导纳特性的影响规律。对换能系统在悬挂有无劈刀和夹持8个松紧度等各个情况下进行谐振频率附近的导纳圆测量,确定换能系统等效电路各特征参数的变化情况。由实验结果的分析可知,劈刀的附加质量以及肋环松紧程度对换能系统谐振频率的影响不大,但劈刀的存在改变了换能系统的能量分布和耗散,是影响换能系统各特征参量的主要因素之一。这些结论有助于超声键合换能系统的优化。

超声监测技术在膜分离过程中的应用研究

在膜分离过程中，膜通量总是随运行时间而下降．为了区分膜污染与浓差极化或者可能的膜形变对通量的影响，和选择适宜的清洗过程，对一种只敏感于膜表面状况的超声测量方法进行了广泛研究．通过平板膜(包括微滤膜、超滤膜和反渗透膜)以及卷式反渗透膜过程的应用实例，说明了这种实时、在线的超声时域反射法即Ultrasonic Time-Domain Reflectometry (UTDR)可以利用它的反射波的振幅和回声抵达超声传感器的时间来监测浓差极化、膜污染(例如CaSO4污染)与清洗过程，也可以用来测量膜的压紧度和污染层厚度．超声测量与传统膜性能测量结果有良好的关联，并具有区域性测量的特性．为了实用化目的，新近的研究进展也作了介绍．
