The Self and Object Representations of Narcissistically Disturbed Children: An Empirical Investigation.

The aim of this study was to demonstrate a correlation between the clinical assessment of narcissistic personality disorder in children and underlying self and object relationships. D. Westen's Social Cognition and Object Relations Scale for the Thematic Apperception Test (1995; D. Westen, N. Lohr, K. Silk, K. Kerber, & S. Goodrich, 1985) was used to compare the object representations of two groups of referred latency-aged children, one for whom narcissistic issues were thought to be primary. Support for the clinical literature, which describes these children as lacking in empathy, struggling with self-esteem regulation, and in poor control of their impulses or aggression, was found. Additionally, a tendency to have a vulnerable sense of identity and to be preoccupied with seeking out and developing relationships with others was found to differentiate these children from peers with similar behavioral and diagnostic profiles. Results obtained have potential implications for the assessment and treatment of narcissistically disturbed children. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

液化石油气储罐火灾模拟试验——池火灾环境下

液化石油气储罐在火灾作用下，其内部的温度和压力会迅速上升，从而可能引起储罐爆炸，进而酿成危害性更大的二次灾害。为此，对液化石油气储罐在池火灾环境下的热响应情况进行了大量的模拟试验研究。研究发现，储罐在池火灾作用下存在着明显的热分层，热分层加速了储罐内部压力升高的速度；储罐内部温度分布和压力响应受到储罐类型、充装水平等因素的影响，压力随时间的变化关系可以用三次多项式加以拟合。     

Surveillance test policy optimization through genetic algorithms using non-periodic intervention frequencies and considering seasonal constraints

In order to maximize systems average availability during a given period of time, it has recently been developed a non-periodic surveillance test optimization methodology based on genetic algorithms (GA). The fact of allowing non-periodic tests turns the solution space much more flexible and schedules can be better adjusted, providing gains in the overall system average availability, when compared to those obtained by an optimized periodic test scheme. This approach, however, turns the optimization problem more complex. Hence, the use of a powerful optimization technique, such as GA, is required.Considering that some particular features of certain systems can turn it advisable to introduce other specific constraints in the optimization problem, this work investigates the application of seasonal constraints for the set of the Emergency Diesel Generation of a typical four-loop pressurized water reactor in order to planning and optimizing its surveillance test policy. In this analysis, the growth of the blackout accident probability during summer, due to electrical power demand increases, was considered. Here, the used model penalizes surveillance test interventions when the blackout probability is higher.Results demonstrate the ability of the method in adapting the surveillance test policy to seasonal constraints. The knowledge acquired by the GA during the searching process has lead to test schedules that drastically minimize test interventions at periods of high blackout probability. It is compensated by more frequent redistributed tests through the periods of low blackout probability in order to improve on the overall average availability at the system level.     

An economic and environmental assessment of biomass utilization in lignite‐fired power plants of Greece

The environmental and socio‐economic impacts of biomass utilization by co‐firing with brown coal in an existing thermoelectric unit in Greece or through its pure combustion in a new plant were studied and evaluated in this work. The 125 MW_e lignite‐fired power plant in Ptolemais Power Station (Western Macedonia) was used as reference system. The environmental benefits of the alternative biomass exploitation options were quantified based on the life cycle assessment methodology, as established by SETAC, while the BIOSEM technique was used to carry out socio‐economic calculations. The obtained results showed clear environmental benefits of both biomass utilization alternatives in comparison with the reference system. In addition, co‐firing biomass with lignite in an existing unit outperforms the combustion of biomass exclusively in a new plant, since it exhibits a better environmental performance and it is a low risk investment with immediate benefits. A biomass combustion unit requires a considerably higher capital investment and its benefits are more evident in the long run. Copyright © 2005 John Wiley & Sons, Ltd.
