A method to estimate entropies and heat capacities applied to alkali oxides

We present a method that is useful in the estimate and assessment of heat capacity data. The approach is based on an analysis of the logarithmic average of the phonon frequencies. In this quantity, that may be easily derived from experimental data on the vibrational entropy, the influence of atomic masses can be exactly accounted for even in polyatomic solids. Our method is applied to Li₂O, Na₂O, K₂O, Rb₂O, and Cs₂O. In particular, literature data for K₂O are critically examined.     

低速爆轰管对黑火药的点传火性能研究

文章采用中心点火管结构的实验装置研究了黑火药的点传火性能。用低速爆轰 (L VD)中心点火管来点燃黑火药时 ,1# ～ 3# 大粒黑药的传火速度为 70 0 m· s-1～ 80 0 m· s-1数量级 ,燃烧波宽度在 3.1ms～ 3.5 ms,最大压力峰值 :1# 为 36 .4 MPa,2 # 为 2 4 .0 MPa,3# 为 38.0 MPa。用普通中心点火管点燃黑火药时 ,2 # 、3# 和钝化 2 # 大粒黑的传火速度分别为 6 1.2 m· s-1、6 8.2 m·s-1和 4 0 .1m· s-1,最大燃烧波宽度分别为 9.2 ms、6 .3ms和 9.5 ms。燃烧波表明 ,L VD中心传火管与普通中心传火管相比较 ,在传火管的不同位置处 ,前者的 P- t曲线一致性远高于后者。

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.

Fatigue behaviour of a phenolic matrix composite

This paper presents results of a fatigue life investigations carried out in plate specimens of a fibre-glass-reinforced phenolic matrix composite. Tensile and Young's modulus data were obtained at four different testing temperatures (room temperature, 100, 150 and 200 °C). The fatigue S−N data were obtained at room temperature only and for two stress ratio values (R=0 and 0.4). Fatigue and tensile behaviour was assesesed in the composite with the fibres aligned in the longitudinal loading direction. The results were obtained for two values of volume fraction (0.28 and 0.42) and three different glass surface treatments. A detailed comparison of fatigue results is given taking into account several fatigue parameters and also the testing variables. Results of observations of SEM fracture surfaces are also presented.

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.
