基于实测与模拟的古村落巷道风环境研究

以传统古村落柯大兴村为例,先使用实测方式,用风速仪测量柯大兴古村落的各个巷道的风速,将测得的风速数据进行分析后,得出柯大兴村的整体风环境状况。再对柯大兴村落进行地形建筑的三维建模,在此基础上用phoenics对其风环境模拟,得出柯大兴村在测量当天的风环境状况,对其进行风环境评价。

由“光辉城市”理论入手对比路易斯·康与柯布西耶

早在20世纪20—30年代,柯布西耶就针对当时城市急速扩张产生的问题提出了一套关于城市可持续发展的解决方案。而被誉为"建筑诗哲"的路易斯·康在设计生涯之初便开始研究柯布西耶的理论,并成为现代主义建筑师,所以在他的思想和理论中不难发现与柯布西耶重合的部分。该文尝试将柯布西耶的"光辉城市"理论作为切入点,在剖析柯布西耶城市理论的同时,从"光辉城市"中探究出路易斯·康与柯布西耶的思想重合点,从而进行梳理分析,在关联与差异中更彻底地研究路易斯·康与柯布西耶的设计思想。     

污水再生工艺去除病原体效果的评价

为考察常用城市污水再生回用工艺去除病毒的效果,采用柯萨奇B3型病毒(CoxB3)作为肠道病毒示踪剂进行试验.首先向污水厂二级处理出水中人工投加已知浓度的病毒,然后分别采用混凝/沉淀/过滤、超滤、氯消毒和臭氧消毒对其进行处理,并分析处理前后病毒的组织培养半数感染剂量(TCID50).结果表明,混凝/沉淀/过滤对大肠菌的去除率为2-lg～3-lg,对柯萨奇病毒的去除率约为1.83-lg;氯消毒和臭氧消毒可以有效杀灭大肠菌,在消毒剂浓度为1～10mg/L、余氯浓度为1～6 mg/L、pH为6～7的条件下,氯消毒对柯萨奇病毒的去除效果不佳,臭氧消毒对柯萨奇病毒的去除率则随臭氧浓度的不同而在1.33-lg～3.83-lg变化;超滤可有效去除大肠菌,对柯萨奇病毒的去除率为2.33-lg.

机器与和谐:纯粹主义时期勒·柯布西耶建筑中的准自主性

聚焦纯粹主义时期勒·柯布西耶建筑中的自主性,分析现有论述,并进行重建。研究展开过程如下:首先,澄清此前研究中从多米诺体系来认识勒·柯布西耶建筑中的自主性之谬误;其次,讨论将形式主义的自主性应用到勒·柯布西耶建筑中的不合理性;再次,建立从机械论来认识勒·柯布西耶建筑中自主性的新的可能;最后,阐明勒·柯布西耶的建筑需要服从外在的和谐目的,故将其视为一种准自主性。围绕自主性这个建筑学的核心概念之一,提出了一个新的视角来认识纯粹主义时期勒·柯布西耶的建筑。

Place-Making in Megaprojects in Melbourne

This article analyses state-led place-making practices in Melbourne. The two levels of government that influence planning in Melbourne make much of the city as ‘culturally vibrant’ and ‘creative’, and have incorporated creative city-inspired place-making principles into many layers of the planning system. An examination of the development of two mixed-use megaprojects in central Melbourne reveals however that ideals of culturally engaging public places, and indeed of creative landscapes for middle-class consumption, wither in the face of more basic imperatives for economic development. In these case studies the ‘creative city’, no matter how the idea is interpreted, has little traction either as a set of inclusive place-making principles or as a gentrification strategy. The article concludes that the creative city-inspired place-making objectives in the planning system at both state and local levels are ambiguous in their overall intents and completely unsupported by statutory controls. Such place-making objectives as are realised are the compromised results of the interplay of uncoordinated decisions, delivered at the pleasure of the developer.     

Pathogens in septage in Vietnam

Septage is widely acknowledged as a major source of infectious pathogens while disposal of septage, and the operation and maintenance of septic tanks, is not regulated in many developing countries. Twenty untreated septage and septage sludge samples were taken from Can Tho City, Vietnam to examine their pathogen content, and indicator micro-organisms. Escherichia coli and Enterococcus spp. were detected in all samples, regardless of sludge storage time. Phages were detected in 80% of samples. Salmonella spp. were detected in 70% of the untreated septage and 60% of septage sludge samples. Concentrations of phages and bacteria tested in septage sludge after many years of tank storage were much higher than the expected levels. Helminth ova were present in 95% of untreated septage samples with an average of 450 ova l^− 1, and were detected in all septage sludge samples with an average of 16,000 ova l^− 1. Twelve varieties of helminth ova were identified. More helminth ova varieties in higher concentrations were found in septage than those reported from stool samples. The varieties' frequency ranged from 10% to 50% and Ascaris lumbricoides predominated. Results show that pathogens and indicator micro-organisms, especially helminth ova, accumulate in sludge. Thus helminth ova should be considered when septage sludge is treated and used for agriculture. Proper health protection measures must be applied for people handling septage.

Variation in property taxation in Tulsa

Conclusions It may be reasonably concluded from this study that the range of variation in these ratios of assessed to actual value are of a reasonable size for the great majority of cases. The frequency distribution of these sample ratios was not normal, however, as was assumed a process of this type would produce. On the other hand, the failure of the regression analysis to identify any significant variables which would explain these variations would tend to re-enforce the assumption that the fluctuations were indeed of a random nature.To sum it up in one paragraph, aside from a few extreme cases, the assessing process appears to give estimates which are more consistent than would be expected under the assumption that any errors would be of a random nature, but the regression analysis was unable to isolate any particular socioeconomic characteristics which would explain the variation which was present.Financial support for this research project was furnished by the University of Tulsa.
