New Labour and Community Protests: the Case of the Govanhill Swimming Pool Campaign, Glasgow

Taking the case study of a community based protest against the closure of a swimming pool in Glasgow, this paper seeks to raise important critical questions about some of the key ideas informing New Labour's urban policy agenda: social capital and active community. It argues that normative notions of active citizenship seriously conflict with bottom-up community protests, highlighting in the process issues of power and inequality. Against claims that New Labour is promoting government through community, here we claim that in the context of this community protest, there was government against community.     

Distribution and Fate of Escherichia coli in Lake Michigan Following Contamination with Urban Stormwater and Combined Sewer Overflows

Escherichia coli distribution and persistence in nearshore Lake Michigan were assessed following heavy rains and sanitary sewer overflow (SSO) and combined sewer overflow (CSO) events over a 5-year period, including an 18-day period following 25.4 cm of rainfall in which intensive studies were conducted following multiple CSO and SSO events. E. coli levels in the Milwaukee estuary and harbor following SSO and CSO events ranged from 10⁴ to nearly 10⁵ CFU/100 mL, which were significantly higher (p ≤ 0.05) than levels following rainfall alone. Sites outside of the breakwall but within the contamination plume (e.g., within 2 km of the harbor) were an order of magnitude lower. Locations 2–5 km from the harbor ranged from below detection limits, of < 1 to 5 CFU/100 mL. E. coli levels corrected for dilution based on specific conductivity measurements were lower than what would be expected for loss due to dilution alone, suggesting a combination of die-off and dilution, were responsible for the rapid disappearance of these organisms outside of the harbor. E. coli and fecal coliforms measured concurrently demonstrated that fecal coliforms could be recovered longer than E. coli in the open waters of the lake. E. coli isolated directly from sewage treatment plant influent were found to have a marked increase in antibiotic resistance traits for ten antibiotics commonly used in the human population compared with isolates from two animal sources of fecal pollution. However, E. coli obtained from sewage impacted water (n = 2,513) and from stormwater impacted water (n = 1,465) collected the previous year when there were no sewage overflows, were found to have no significant difference (p < 0.05) in the frequency of resistance when comparing the two conditions. E. coli survival characteristics and population dynamics are most likely influenced by multiple factors in complex systems such as the watershed/estuarine/lake environments of the Great Lakes.     

HULL GESTURE AND RESISTANCE PREDICTION OF HIGH-SPEED VESSELS

Since trim and sinkage are significant while vessels are advancing forward with high speed, the predicted vessel resistance based on restrained model theory or experiment may not be real resistance of vessels during voyage. It is necessary to take the influence of hull gesture into account for oredicting the resistance of high-speed ship. In the present work the resistance problem of high speed ship is treated with the viscous flow theory, and the dynamic mesh technique is adopted to coincide with variation of hull gesture of high speed vessel on voyage. The simulation of the models of S60 ship and a trimaran moving in towing tank with high speed are conducted by using the above theory and technique. The corresponding numerical results are in good agreement with the experimental data. It indicates that the resistance prediction for high speed vessels should take hull gesture into consideration and the dynamic mesh method proposed here is effective in calculating the resistance of high speed vessels.     

STUDY ON THE AIRFLOW RESISTANCE IN NATURAL DRAFT COOLING TOWERS

A new approach for improving the calculation of the airflow resistance coefficient of natural draft cooling towers from the inlet to throat (4) has been presented in this paper. The suggested equations areWhere. ζ1 is the coefficient of the airflow resistance with no consideration of waterdrop in rain zone, ζ2 is the coefficient of the airflow resistance due to falling of waterdrop in rain zone, s is the rate of the inlet area to the area at elevation of the packing, q is the water loading, V0 air velocity at the packing section.

CYP2C19基因多态性联合血栓弹力图指导冠心病介入术后抗血小板治疗的临床研究

摘要 目的 探讨CYP2C19基因多态性联合血栓弹力图指导下的抗血小板个体化治疗对冠状动脉粥样硬化性心脏病（冠心病）支架植入术后患者临床预后的影响。方法 入选2015年06月至2016年04月因冠心病（CHD）就诊并成功完成经皮冠状动脉介入术（PCI）的患者168例,最终纳入符合条件的患者124例。全部完成CYP2C19基因型及血栓弹力图(thrombelastography,TEG)检测。根据基因型将患者分为氯吡格雷正常代谢型(包括正常和超代谢型)和异常代谢型(包括中间和慢代谢型)2组。并采用改良（thrombelastography,TEG）法测定腺苷二磷酸（adenosine diphosphate, ADP)诱导的血小板抑制率。根据ADP诱导的血小板抑制率分为氯吡格雷正常反应型(NCR, 血小板抑制率≥30%)和氯吡格雷低反应型(LCR, 血小板抑制率＜30％)。结合基因型及TEG的检测结果,将基因型为正常代谢型+TEG结果为NCR患者分为A组;正常代谢型+TEG结果为LCR或异常代谢型+TEG结果为NCR组归为B组;异常代谢型+TEG结果为LCR组为C组。A组及B组给予阿司匹林+氯吡格雷抗血小板,C组给予阿司匹林+替格瑞洛抗血小板治疗。随访三组9~12个月内主要出血事件和不良心血管缺血事件的发生率。结果 三组患者性别、年龄、高血压、糖尿病、高脂血症、吸烟、多支病变、支架植入数量、辅助检查（总胆固醇、高密度 脂蛋白胆固醇、低密度脂蛋白胆固醇、肌酐、尿酸）等方面均无统计学差异（P均>0.05)。 A组及B组安全终点（主要出血事件）和疗效终点（主要不良心血管事件、靶血管病变再狭窄、再发心绞痛）无统计学差异（P均>0.05),C组安全终点高于A组及B组。结论：根据CYP2C19基因型联合TEG指导PCI术后抗血小板治疗能降低心血管终点事件的发生,对于氯吡格雷基因型为中间代谢型/慢代谢型且同时合并ADP抑制率<30%的患者应给予阿司匹林+替格瑞洛抗血小板治疗。
