Design defects are experienced in many projects; the difference is only in the extent of occurrence. This technical note discusses a design error case in a building project in Nepal, where the designer made the wrong assumptions in roof treatment work for waterproofing as well as for heat insulation purposes. From the investigation of the problem, it was found that the waterproofing polymer was not applied directly over concrete slab top. Use of heavy concrete block as a heat insulation material also helped to increase the leakage problem. The problem evoked loss of prestige for project officials, the design consortium, and the contractor.  相似文献

女性护理液为中药苦参醇提液加三氯羟基二苯醚复配而成,根据药理方法学以实验动物建立模型,观察护理液的抗炎、止痒作用。结果,单独使用三氯羟基二苯醚,有较好的抗菌消炎作用,但是止痒作用不明显。以苦参醇提液和三氯羟基二苯醚复配,其抗炎、止痒作用均接近地塞米松磷酸钠注射液。  相似文献

A generalized Bayesian inference framework in order to embed fuzzy sets and partial probabilistic information is provided. The general framework of reference is that of coherent conditional probabilities, which allows giving a rigorous interpretation of membership function as a conditional probability, regarded as a function of the conditioning event. The inferential problem needs to be studied in situations where the prior can be partial; moreover, membership and prior can be given on different classes of events. This inferential model is applied for the virtual representation of a female avatar.  相似文献

为了解高校女教职工妇女病患病情况、做好妇女保健提供依据,本文对2011年我校女教职工妇女病检查结果进行统计分析。结果显示全校女教职工1139人,2011年参加妇检的女教职工共计654人,参检率57.42%,参检率较低。654名参检人员中,最常见的妇科疾病是宫颈炎、乳腺增生,分别占患病人数的44.65%和41.53%,其次是子宫肌瘤、阴道炎,分别占患病人数的6.18%和4.87%。从结果中可以看出高校女教职工参检率低、患妇女病率偏高,应提高保健意识,充分认识到定期体检的重要性。  相似文献

This paper begins by identifying the growth in female-headed households in Australia. Despite this increase, it is argued that females still lag males in terms of home ownership rates (HORs) with women in Australia facing similar ownership challenges as those experienced in the UK and the USA. In seeking to establish any dynamic change, the study analyses female home ownership rates in Australia for two points in time, 1998 and 2008. Logit models are used to predict HORs. The results indicate that factors such as household type, income and source of income have an impact on rates of ownership. The paper concludes that female-headed households in Australia show an increasing propensity to purchase which match, or even exceed, those of male-headed households.  相似文献

The practice of architecture is very similar in different national settings despite what may be very different sociological and cultural origins of the profession, the attendant variances in how work is organized and distinctions in equality and gender roles. The aim of this paper is to examine the quest for equality in architecture for women in the UK and Spain reporting the findings of a comparative study into women architects’ careers in the two countries. Within the qualitative paradigm, semi-structured in-depth interviews were carried out with a total of 55 women architects in the UK and Spain. Findings indicate surprising differences in levels and terms of equality for women in the two countries and marked differences in women’s experiences of working as an architect. Women have come to the profession in Spain much later than their British counterparts and, somewhat surprisingly, are present in greater numbers. However, despite there being more of a ‘critical mass’ this has not served to improve their situation; they report much higher levels of discrimination and find it difficult to progress in their careers. Conclusions argue for a stronger approach by the professional bodies to help improve the position of women.  相似文献
