DEVELOPMENT AND VALIDATION OF AN MMPI SCALE OF ASSAULTIVENESS IN OVERCONTROLLED INDIVIDUALS.

REPORTS THE DERIVATION, STANDARDIZATION, AND CROSS-VALIDATION OF AN MMPI SCALE, O-H (OVERCONTROLLED HOSTILITY), WHICH DISCRIMINATES OVERCONTROLLED FROM UNDERCONTROLLED ASSAULTIVE CRIMINALS, NONVIOLENT CRIMINALS, AND NORMALS. SEVERAL CONSTRUCT VALIDITY STUDIES ARE PRESENTED WHICH INDICATE THAT THE SCALE IS SENSITIVE TO A MIXTURE OF SELF-CONTROL, HOSTILITY, AND ALIENATION. THE DATA ARE INTERPRETED AS SUPPORTING THE THEORY THAT ASSAULTIVE CRIMINALS CAN BE DIVIDED INTO OVERCONTROLLED AND UNDERCONTROLLED TYPES. THE USEFULNESS OF O-H IN CLINICAL ASSESSMENT AND IN PERSONALITY RESEARCH IS DISCUSSED. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Densification Mechanisms in Hot–Pressing of Magnesia with a Fugitive Liquid

Densification of MgO with LiF additions depends on the formation of a liquid that is initially a lubricant for rearrangement of particles and later a material transport medium for pressure–enhanced liquid–phase sintering. The rate–controlling process in the latter stage is viscous flow of the liquid through grain–boundary channels. After the liquid is distributed as a uniformly thin film between the MgO grains, it can be removed by evaporation, and transparent polycrystalline specimens are produced.     

Theory for the Load Relaxation Technique in Fracture Studies Using Four-Point-Bend Chevron-Notched Specimens

The load-relaxation technique is reviewed using the energy approach for four-point-bend chevron-notched samples. The influence of the sample and bending geometry and the stiffness of the testing system on the strain-energy release rate is considered. Proper experimental design allows the study of fracture initiation, propagation, and arrest, Special attention is paid to the effect of overload at fracture initiation on crack propagation. It is concluded that the chevron–notched sample offers great flexibility for gaining information on the fracture properties of ceramic materials.     

THE WEB,THE PUBLIC,AND THE GLOBAL WARMING DEBATE

The World Wide Web is a popular source of information on the environment. The global warming controversy, an important environmental problem, has very extensive Web coverage, yet no detailed analysis has been made of its treatment on the Web. Our paper attempts to remedy this lack of analysis. It first analyzes the scientific controversy about global warming, then examines its current treatment on the Web, contrasting it with the treatment in elite science journals. The paper further discusses the direction the controversy on the Web will most likely take in the future. We conclude that although the debate on global warming science has been very widely treated on the Web, the future is likely to see the controversy shift to questions of the appropriate response to climate change. We argue that this new phase of the controversy is likely to become even more prevalent on the Web as the controversy moves from the scientific arena to the political.     

A new approach for the design of multivariable feedback systems

A new design technique for multivariable feedback systems is presented. In this approach, n —1 open-loop transfer functions at different inputs of the plant, with all other feedback paths closed, are specified in advance, and are achieved exactly. The nth open-loop transfer function is a by-product of the design process, such that the overall feedback system is stabilized. The design approach is fitted to solve problems in which the plant elements can have non-stable poles and non-minimum phase zeros. The design process is straightforward, no iterations are necessary, and the achieved design copes exactly with the design specifications. The gainbandwidths of the different lis and the overall loop gain l* might be constrained due to non-stable poles and zeros of the plant elements. Based on the obtained different loop gains, any input output matrix T can bo achieved with the aid of an appropriate prefilter matrix F.     

RECENTLY IDENTIFIED ENZYMES OF BREVIBACTERIUM LINENS ATCC 9174 - A REVIEW

An extracellular proteinase and an aminopeptidase and an intracellular aminopeptidase and esterase were isolated from Brevibacterium linens ATCC 9174. The proteinase was a serine enzyme with relatively broad specificity onα_s1-andβ-caseins. The extracellular aminopeptidase was a metallo enzyme but the intracellular aminopeptidase was a thiol enzyme with rather narrow specificity for small side chains, e.g., Gly and Ala. The organism possessed two intracellular esterases, one of which was purified to homogeneity. This enzyme was a tetramer of MW 200 kDa, was strongly inhibited by thiol blocking agents and showed a high specificity for short chain fatty acids with no lipolytic activity on tributyrin or milk fat.
