Review of Child sexual abuse: Critical perspectives on prevention, intervention, and treatment.

Reviews the book, Child sexual abuse: Critical perspectives on prevention, intervention, and treatment edited by Christopher R. Bagley and Ray J. Thomlison (1991). This book is a compilation of a series of literature reviews originally commissioned by Health and Welfare Canada in 1987 and completed in 1988. The individual papers included in this edited version represent a cross section of Canadian academicians, clinicians, and case workers who are integrally involved in the policies and practices regarding child sexual abuse in Canada. The work provides a comprehensive perspective on prevention at the primary, secondary, and tertiary levels. The list of authors is impressive in terms of their expertise and experience. At a time when numerous books on child sexual abuse are appearing on the market, it is nice to see a book that has some unusual aspects. Aside from its distinctly Canadian perspective, the book addresses several important, yet frequently ignored, topics. The book provides an up-to-date review of several core issues: conceptualization of the problem, prevention strategies, impact of sexual abuse, investigative interviewing, treatment outcome studies, and treatment issues for child molesters. The more unique topics include a review of the strategies used to evaluate prevention programs, prevalence rates among a number of special populations, the role of medical practitioners in preventing and intervening in child sexual abuse, and sexual abuse and exploitation among disabled individuals. Overall, I can recommend this book for clinicians and researchers in Canada and elsewhere who are interested in child sexual abuse. This compilation of literature reviews highlights the leading role that Canadian social service agencies have taken in developing programs for sexually abused children and their families.

碳纤维表面处理对铝电解用硼化钛阴极涂层性能的影响

硼化钛阴极涂层是铝电解用可润湿性阴极材料中的一种，具有优良的抗钠渗透性和对铝液润湿性，可以有效地延长铝电解槽寿命。碳纤维是硼化钛涂层材料的增强剂之一．对硼化钛阴极涂层的性能影响很大。本文研究了不同工艺的液相碳纤维表面氧化处理法对硼化钛阴极涂层抗拉强度和粘接强度的影响。采用PTIR检测碳纤维处理后表面含氧基团的变化，寻找影响硼化钛阴极涂层性能的原因，从而达到最有效地提高TiB2阴极涂层抗拉强度和粘接强度的目的。结果表明，采用工艺(1)(10％HNO3，80℃、恒温5min．超声波、5min)对碳纤维进行表面处理最合理，处理后碳纤维表面含氧基团的含量最高．用其制备硼化钛阴极涂层的抗拉强度、粘接强度最大。

Silver Electrodeposition from Photographic Processing Solutions

This paper describes the parameters that are important in the industrial practice of silver removal from photographic fixers. The experiments were performed under potentiostatic control using synthetic solutions. The current efficiency was analysed as a function of the cathodic potential taking into account the deposit quality. A cathodic potential of ?0.5 V against a saturated calomel electrode is recommended. The conditions to prevent the darkening of the electrodeposit were investigated. The determination of silver concentration in the solution was made by direct potentiometry. The results obtained with synthetic fixers were corroborated by making the silver deposition from commercial fixers in an electrochemical reactor with rotating cylinder electrode intercalated in an electrolytic flow circuit in order to simulate practical conditions.     

提高K-9曲拐质量的热处理工艺

K-9曲拐质量不合格主要是由于热处理后，珠光体数量太少所引起。因此应用正交试验，合理地选择了热处理工艺参数，提高了出炉温度，增加了珠光体数量，解决了K-9曲拐的质量问题。     

淀粉液化液灭酶方法的研究

某些情况下淀粉液化液需要严格控制液化的程度 ,因此需要及时终止残余淀粉酶的活性。实验用降低液化液 pH值、升高温度、以及两者并用等 3种方法结束液化反应过程 ,实验结果可作为工业生产过程参考。
