APPLYING TECHNOLOGY ADVANCEMENTS TO IMPROVE HEAT EXCHANGER ECONOMIC AND ENVIRONMENTAL PERFORMANCE IN REFINERY CRUDE PREHEAT TRAINS

Fouling of heat exchangers in crude preheat trains is a major refinery operations business factor. It is realised that fouling cannot be completely eliminated, but considerable economic and environmental benefits are available with the proper application of improved technology in both the equipment and software asset management tools areas. This paper presents a technology update of refinery applications of a heat exchanger network analysis software to identify optimal crude preheat train cleaning

Social skills training for juvenile delinquents:Post-treatment changes

Objectives To examine the post-treatment effectiveness of an outpatient, individual social skills training for juvenile delinquents in the Netherlands and to conduct moderator tests for age, gender, ethnicity, and risk of reoffending. Methods The sample consisted of juveniles who received Tools4U, a social skills training with a parental component, as a penal sanction (N = 115). Propensity score matching was used to select a control group of juveniles receiving treatment as usual (TAU) of n = 108 juveniles (of a total of N = 354). Assessment of impulsivity, social perspective-taking, social problem-solving, critical reasoning, developmental task-related skills, and treatment integrity took place before and immediately after the treatment. Results Treatment integrity was found to be sufficient, so that treatment effects could be attributed to the Tools4U training. Tools4U was more effective than TAU in reducing impulsivity, cognitive distortions (self-centering and assuming the worst), and social perspective-taking deficits (hostile intent attribution). No treatment effects were found on adolescents’ social problem-solving skills, and only caretakers of girls showed improvement in parenting skills. Effects on developmental task-related skills were not in the expected direction: after Tools4U, juveniles reported significantly less social acceptance and self-worth than juveniles receiving TAU. Conclusions Tools4U showed generally small effects and no effects on protective factors, which might limit the long-term treatment effects on delinquency. Treatment effects may be improved by implementing additional techniques and improving the parental component for boys in particular

Het Blokhuis te Harlingen, Weeshuisstraat 1/3

On the occasion of the demolition plans for the boarding school of the Noordzeecollege a building-historical research took place in two phases. It was established that the oldest part of the complex was built in 1500, probably as a warehouse building on the blockhouse. The blockhouse was a rectangular fortress measuring approximately 115 x 145 metres with revetted earth ramparts and two round bastions. The bastion on the south-east side was a later addition. Within the fortress there were various buildings around a parade ground. In the Eighty Years\u27 War the blockhouse was dismantled, after which around 1600 the former warehouse building was redesignated as town orphanage. In 1958 the building obtained its present function as boarding school. In the course of time a lot of refurbishments took place, so that at present the building has a primarily I9th and 20th century appearance. On the basis of the research results an evaluation was drawn up, in which e.g. the special historical values of the building as part of the blockhouse were pointed out, the significance of the orphanage for the town of Harlingen and the building-historical values of the walls and the single oak joisting (from 1500). After careful consideration it was decided to maintain the building and convert it into apartments
