Earthquake Engineering and Engineering Vibration 2015年第2期14卷 275-293页

An indexing method for rapid evaluation of the seismic vulnerability of infi lled RC frame buildings in Jordan is proposed. The method aims at identifying low and medium rise residential buildings as safe or in need of further detailed evaluation. Following a rapid visual screening, the building is assigned a Basic Capacity Index(BCI); fi ve performance modifi ers are identifi ed and multiplied by the BCI to arrive at the Capacity Index(CI) of the building. A Capacity Index lower than a limit CI value indicates that the screened building could experience moderate earthquake damage whereas a higher value implies that minor damage, if any, would take place. To establish the basic evaluation parameters; forty RC frame buildings were selected, designed and analyzed using static nonlinear analysis and incorporating the effect of infi ll walls. Effects of seismicity, local site conditions, horizontal irregularities(setbacks and re-entrant corners), vertical irregularities(soft story at ground fl oor level) and overhangs on the seismic performance of local buildings were examined. Assessment forms were designed and used to evaluate and rank 112 sample buildings. About 40% of the surveyed buildings were found to be in need of detailed evaluation to better defi ne their seismic vulnerabilities.

Autoimmune disease management presents a significant challenge to medical science. Environmental factors potentially increase the risk of developing inflammatory and autoimmune diseases, such as multiple sclerosis, rheumatoid arthritis, and lupus. Among various environmental stresses, cigarette smoke and hypoxia have both been reported to lead to an enhanced risk of inflammatory and autoimmune diseases. In this review, we shed light on all reported mechanisms whereby cigarette smoke and a hypoxic environment can induce inflammatory and autoimmune diseases and discuss how hypoxic conditions influence the cigarette smoke-induced threat of inflammatory and autoimmune disease development. Cigarette smoke and hypoxia both lead to increased oxidative stress and production of reactive oxygen species and other free radicals, which have various effects including the generation of autoreactive pro-inflammatory T cells and autoantibodies, reductions in T regulatory(Treg) cell activity, and enhanced expression of pro-inflammatory mediators [e.g., interleukin-6(IL-6), interleukin-4(IL-4) and interleukin-8(IL-8)]. Accordingly, smoking and hypoxic environments may synergistically act as potent environmental risk factors for inflammatory and autoimmune diseases. To our knowledge, no studies have reported the direct association of cigarette smoke and hypoxic environments with the risk of developing inflammatory and autoimmune diseases. Future studies exploring the risk of autoimmune disease development in smokers at high altitudes, particularly military personnel and mountaineers who are not acclimatized to high-altitude regions, are required to obtain a better understanding of disease risk as well as its management.

Enhanced oil recovery by CO_(2) injection technology(CO_(2)-EOR)plays a crucial role in enhancing oil production and the permanent sequestration of anthropogenic CO_(2) in depleted oil ***,the availability of CO_(2) in oil field locations and its mobility in contrast with reservoir fluids are prime challenges in CO_(2)-*** cost of CO_(2) and its availability at the oil fields has prompted investigations on efficient injection of CO_(2) at the fields to achieve the best sweep efficiency *** strategies such as water-alternating-gas(WAG),simultaneous vertical and horizontal WAG,simultaneous water injection into the aquifer and vertical WAG,water and gas injection simultaneously but separately(SS-WAG),and water and gas injection simultaneously but not separately(SNS-WAG)play a significant role,as well as the purity of CO_(2).In this work,the significance of the above criteria was investigated indi-vidually and in *** coupled sequence of injection rate,soaking time,WAG ratio,and purity of injected CO_(2) for enhancement of oil production were delineated.A realistic reservoir simulation model conceptualizing the CO_(2)-EOR system with five spot injection patterns was developed by the company *** history-matched model that was developed was used to investigate the sensitivity of the coupled effects to the criteria listed above on oil *** investigations quantitatively emphasized that purity and soaking time of CO_(2) have an inverse effect in the oil production rate and that SNS-WAG resulted in a better oil production rate than SS-WAG.

本研究旨在解释典型清真寺内的主要空间和清真寺建筑的朝向需求。通常在谈论建筑设计时,我们需要理清客户需求。客户需求解释了用户的要求,然后建筑师根据客户的要求设计建筑。与其他建筑物相比,清真寺的设计是不同的,例如,清真寺内部有一些最基本的主要空间,因此每个典型的清真寺设计都应该有这些空间。除了主要空间外,还需要回应客户需求,因为每个社会都有其自身的传统和文化,他们会根据自己的传统在清真寺中保留次要空间。通常在设计建筑时,我们首先考虑的是光线、新鲜空气、通风和使用者的可达性,然后才是关注美学和其他措施。此外,设计清真寺时,清真寺的建筑朝向是最重要的。因此,本研究针对清真寺的建筑朝向展开讨论;探讨了典型清真寺建筑的正确朝向,以及伊斯兰教关于清真寺建筑朝向的规定的起源。此外,本研究介绍了作者去年设计的五座巴基斯坦清真寺的建筑平面图。通过这几个例子,进一步艺术地描绘了世界其他地区现有清真寺的图景。此外,本研究重点关注了联合国教科文组织预备遗产地点:巴德沙希清真寺(Badshahi Mosque Lahore,BMLH,1671-1673),这座寺庙由莫卧儿帝国皇帝奥朗则布·阿拉姆吉尔(AA)建造。这处遗产的特别之处在于它在1673年至1986年期间拥有着“世界上最大的清真寺”称号(可容纳10万人),因而具有重要的建筑意义,同时巴德沙希清真寺也是世界著名旅游景点之一。各种清真寺建筑(MA)在全球范围内出现(超过1400年),以保留每个地区的多样性、身份和文化。我们通过文献资料学习的方法对这个遗址展开研究,在这个过程中感受和探讨几十年来形式统一莫卧儿建筑的真实性。此项研究发现,BMLH在保持原始清真建筑的同时经历了重大改变。这项独特的研究进一步关注了莫卧儿时代的基本建筑。通过对BMLH的建筑主题进行详细研究,我们发现这一遗产的建筑风格受到了区域、文化和传统三个方面的影响。通过分析BMLH的建筑主题和独特特点,我们也揭示了区域、宗教和心理对莫卧儿时代清真寺建筑发展的独特影响。论文进一步通对巴德沙希清真寺的当前结构状况进行记录,指出了渗漏问题的数量,并在调研期间发现了一些衰败的现象。为了更好地保护这一重要遗产,建议在未来采用更加完善的保护策略。为了加强我们的研究,我们还调查了河南商丘市的西关清真寺和先贤清真寺此外。我们对Badshahi清真寺、西关清真寺和先贤清真寺(Abi Waqas)的建筑进行了比较。通过表格,我们绘制出了一些相似之处和差异,反映出巴基斯坦和中国地区建筑风格对清真寺的影响。

当前的世界面临着许多严重的问题,其中之一便是对人类社会中高危疾病的病发风险预测。在临床实践中,疾病预测研究需要获取一些重要信息,例如相关数据,以便能够正确且及时地诊断某些疾病。目前,许多研究尽管已经使用了一些机器学习工具来达到这个目的,但是由于各种原因,例如缺乏适当的数据、数据不均衡、多数和少数类之间的不平衡,或者使用不恰当的不变量来分析数据,这些工具的效果并不理想。由于缺乏这些数据所代表的具体含义,正确的诊断和分类变得十分困难,这可能导致全球许多患有高危疾病的群体只能面对死亡。在最近的研究中,针对不同疾病的案例(如心脏病、糖尿病、肾脏病和帕金森病),研究人员正在使用机器学习技术解决高危疾病预测问题。机器学习技术是一种新兴技术,以克服这些问题。本研究为了解决这个问题,提出了再平衡的算法模型LUSI(使用再平衡的统计不变量进行学习),并且与LSSVM方法进行比较。通过使用F-Measures、GMeans和平均精度等指标对结果性能进行评估。研究结果表明,针对心脏病、糖尿病、肾脏病和帕金森病,LUSI的平均准确率分别为99.65%、74.26%、99.82%和92.31%。相比之下,使用LSSVM在这些疾病的评估中表现相对较低,其准确率分别为99.60%、64.88%、72.65%和72.65%。实验结果表明,LUSI方法在高危疾病数据集上表现良好,这是由于该算法模型能够完美地估计数据比例,利用特征组合的信息进行学习。因此,当前的研究得出结论,LUSI是一种有效的方法,可用于正确诊断多种不同的疾病,包括心脏病、糖尿病、肾脏病和帕金森病。
