Introduction: The tuberculosis (TB) and HIV co-infection is a deadly combination, each accelerating the progression of the other. TB, caused by Mycobacterium tuberculosis (M. tuberculosis), is the leading cause of deaths among people living with HIV, accounting for around 40% of all HIV-positive deaths. The aim of this study was to estimate the prevalence of the tuberculosis-HIV co-infection in women. Material and Methods: The study population consisted of all suspected patients visiting the laboratory of the Bogodogo University Hospital, from May 2023 to January 2024, to be screened for M. tuberculosis. This was a descriptive cross-sectional study. Socio-demographic data were collected during individual interviews with consenting patients. M. tuberculosis was identified using the GeneXpert device, and HIV was diagnosed using the Abbott Determine diagnostic test. Results: Our study population was aged, on average, 37 ± 17.5 years. The overall tuberculosis infection rate was 65%, and 35% were married. Housewives were the most infected with 22.5%. The most infected age group was the ]20 - 40], with 32.5%. Some 37.5% of the women were anorexic and 45% had asthenia. Of the suspected cases, 47.5% were people who had contact with infected persons. TB/HIV co-infection was 5%. Conclusion: Tuberculosis is still rife in many parts of the world. It infects both men and women very quickly. HIV-tuberculosis co-infection is a reality, with HIV accelerating the progression of tuberculosis and vice versa. Raising awareness of HIV and tuberculosis should be done in tandem, as their co-infection leads to a poor vital prognosis.

Influence of Anisotropic Permeability and Soret Effect on the Convective Heat and Mass Transfer through a Porous Cavity Saturated by a Non-Newtonian Fluid

引用

Engineering（科研） 2023年第12期15卷 843-866页

作者： dieudonné Kouke Julien Yovogan Laboratoire d’Energétique et de Mécanique Appliquées LEMA-EPAC Université d’Abomey Calavi Cotonou Bénin Université Nationale des Sciences Technologies Ingénierie et Mathématiques Abomey Bénin

In this work, an analytical study is carried out on double-diffusive natural convection through a horizontal anisotropic porous layer saturated with a non-Newtonian fluid by using the Darcy model with the Boussinesq approximations. The horizontal walls of the system are subject to vertical uniform fluxes of heat and mass, whereas the vertical walls are assumed to be adiabatic and impermeable. The Soret effect is taken into consideration. Based on parallel flow approximation theory, the problem is solved in the limit of a thin layer and documented the effects of the physical parameters describing this investigation.

Deploying Safety-Critical Applications on Complex Avionics Hardware Architectures

Journal of Software Engineering and Applications 2013年第5期6卷 229-235页

作者： Robert Hilbrich Laurent dieudonné Fraunhofer Institute for Open Communication Systems (FOKUS) Berlin Germany Liebherr-Aerospace Lindenberg GmbH Lin- denberg Germany.

Aviation electronics (avionics) are sophisticated and distributed systems aboard an airplane. The complexity of these systems is constantly growing as an increasing amount of functionalities is realized in software. Thanks to the performance increase, a hardware unit must no longer be dedicated to a single system function. Multicore processors for example facilitate this trend as they are offering an increased system performance in a small power envelope. In avionics, several system functions could now be integrated on a single hardware unit, if all safety requirements are still satisfied. This approach allows for further optimizations of the system architecture and substantial reductions of the space, weight and power (SWaP) footprint, and thus increases the transportation capacity. However, the complexity found in current safety-critical systems requires an automated software deployment process in order to tap this potential for further SWaP reductions. This article used a realistic flight control system as an example to present a new model-based methodology to automate the software deployment process. This methodology is based on the correctness-by-construction principle and is implemented as part of a systems engineering toolset. Furthermore, metrics and optimization criteria are presented which further help in the automatic assessment and refinement of a generated deployment. A discussion regarding a tighter integration of this approach in the entire avionics systems engineering workflow concludes this article.

摘要：数据仓库和OLAP(Online Analytical Processing)系统允许快速访问和整合海量数据进行分析。从这个意义上讲,数据仓库是BI(Business Intelligence)必不可少的工具。尤其是Hadoop/HBase集群为海量数据的处理和存储提供重要的资源。Hadoop是Apache软件基金会开源项目组的一个子项目,它目的是实现一个分布式执行环境。主要目的是实现有效的批处理,尤其别是当他们涉及到庞大的数据量。因此,Hadoop是有效的、可扩展的分布式执行环境,它主要用来处理大数据。因为该系统的通用性,促进了其一领域有专攻的项目尤其是包括数据仓库、BI(商业智能),数据监控或数据持续性等的生态化发展。通常存储和管理数据仓库的所有组件都集中在一个服务器上。当它的容量达到限制,解决方案通常是复制存储产品的特性进行处理。在分布式系统的使用上,需要实现并行计算和分布式数据存储。在Hadoop/HBase集群的基础设施上部署仓库,需要用多维模型和OLAP程序去适应和反映数据的分布和聚集过程。在设计数据仓库时,多维模型的维度被优先定义为数据分析轴并呈现给用户。维度中实际使用的可能性有维度的概念模型和仓库数据的有效性来决定。数据的可用性和聚合在分布式存储中尤为重要,例如HBASE集群,每个节点存储数据仓库的一个子集。多维模型实体化基于水平片段的预计算聚合表。仓库模型还必须考虑到这样一个事实：HBase也是一个面向字段的数据库多维模型利用水平片段聚合表和HBase数据库面向字段的性质。数据的可用性,特别是在这种争议的分布式数据不是微不足道的。所以本文介绍了一个仓库数据识别的模型和一个用多维块索引数据的方法。在分布式数据仓库搜索可用的数据需要一个明确的数据标识。该模型利用OLAP查询引用数据仓库的数据。这些数据分成块,由于大量的数据块块被定义的概念。这些数据被分为块,同时因为大量数据块被定义。事实上,一个OLAP查询包括选择一个或多个维度的成员或他们的总量和各种措施。识别模型是基于实例的成员的维度。这些标识符使用HBase上的表的ROW KEYS来发布他们的数据。多维数据的分布式管理工作主要是基于一种细分的数据仓库的基本单位分配标识符。“块”的概念被用于工作的上下文数据存储在磁盘上的优化和客户端缓存管理的远程数据存储。这些系统使用的“块”大小不同取决于管理磁盘块或查询结果缓存的大小。一种索引结构来支持这两个以前的模型是基于块的块和基于长方体晶格索引的索引,并允许本地数据实体化在不同的集群节点上。第一个索引,即Cuboids Index在晶格结构中未定义和区分各级聚集。第二个指标,即块块索引是基于索引的内容块的块。最后,CCB指标是这两个指标的结合。当时的数据搜索查询,该指数提供了可用的物化块没有经常过处理。此外,信息多维模型可以推断出所有可计算的总量。实体化块调度模块做了针对你查询效率的改进提出无功调度策略利用批处理模式的维护操作。它还处理在线查询程序和从候选块列表中建立一个优化的执行计划,输出到查询结果中。调度查询有两个主要线路即这些查询请求的执行计划和查询执行。我们的调度称为无功,因为它考虑了不同资源的动态变化。用户将进入到仓库,通过在HBase集群上的一个调度引擎来执行它的查询请求。查询引擎必须允许查询分布式仓库因为它是集中的。给定的计算和存储提供的HBase集群,用户必须迅速接收数据搜索的结果和最复杂的聚合数据。为了满足这些需求,分布式存储系统必须与优化过的OLAP查询机制进行联合,以最大限度地减少用户请求的响应时间。环境和Hadoop/hbase集群的可用性通常是高度动态的,根据不同操作参数(数据、节点、网络)和外部的用户数量等参数。我们提出的解决方案如下：首先,执行查询的程序必须有所需的有效数据的信息。然后识别获取查询结果的可能选择。这可以通过数据直接存储在集群获取或通过明细数据的聚合进行获取。从解决方案中选择最低估计响应时间。在本章中,我们定义了在HBase仓库中QUERY程序的不同阶段。我们的调度方法的机制和流程也进行了详细讨论。在本章中,我们充分利用我们的索引结构部署在集群的可用数据提出了在HBase集群仓库中的优化方法和查询的执行方法。这个基于模型的基础设施的唯一标识的多维数据块有助于满足查询识别不同的可能的块。因此,从一个典型的OLAP查询用户,我们已经开发出处理的不同阶段,通过搜索可用的块的优化来减少查询的响应时间。优化阶段产生执行计划的操作拆分为任务并行执行。在被加载到集群前,经过最终筛选的这些任务符合处理程序的约束。最后阶段涉及监控查询性能和最终传递给客户机应用程序的结果。整个查询处理对用户是透

布隆迪是与中华人民共和国有着友好邦交关系的国家。然而,该国曾经长期被沦为殖民地国家,先后由德国和比利时对该国实行殖民统治。虽然该国于1962年宣告独立,并于1966年废除了君主制,建立了民主国家,但独立后长期战乱不断,成为了当今世界上最贫穷的国家之一。近些年来,伴随着中国与布隆迪之间的高层互访不断,受中国影响强烈。布隆迪政府深感必须构建稳定、和谐的社会秩序,努力发展经济,改善国人的生活状况,创造更多的就业机会等是国家工作的重中之重。于是,布隆迪政府在不断构建和维系稳定的国家社会秩序的同时,着手制定了外商投资法,且先后多次对该国的外商投资法进行了修改。客观地讲,布隆迪的外商投资法实施后,该国的社会秩序和经济发展状况等虽然有了明显的好转,但离该国政府预期的目标仍然相去甚远。笔者乃布隆迪选派至中国的留学人员,通过对中国“三资企业法”和新颁布《外商投资法》的研读,深感布隆迪的外商投资法与中国的外商投资法相比,尽管有许多自身的特点,但诚然存在诸多很不完善的地方。有鉴于上,本文基于布隆迪外商投资法与中华人民共和国外商投资法比较研究的视角,以“布隆迪外商投资法研究”作为硕士学位论文选题,试图通过该文阐述布隆迪外商投资法制定的历史背景与重要意义,并通过梳理布隆迪外商投资法的基本内容和主要特点,剖析该国外商投资法存在的主要问题及其原因,然后就如何进一步完善布隆迪外商投资法提出一些基本见解,期盼能为布隆迪外商投资法的完善尽绵薄之力,并以此报答布隆迪政府尤其是中华人民共和国政府对本人求学深造的康概帮助和无私的关怀。全文除引言外主要包括以下4个部分:第一部分,阐述布隆迪外商投资法制定的历史背景和重要意义。首先,阐释布隆迪外商投资法制定的历史背景:布隆迪在被殖民前期和殖民时期由于缺乏制定该国外商投资法的内部环境和外部环境,虽然在与德国等国家的双边协议中涉及外商投资的某些内容,但由于协议双方的地位极不对等,根本不是国家主权意义上的外商投资法。只是到了 1962年布隆迪宣布独立之后,尤其是该国于1966年废除了君主制而建立民主制国家之后,才具备了制定真正国家主权意义上的外商投资法的条件。布隆迪外商投资法的制定不仅具有立法上的意义,而且具有很强的社会现实意义。第二部分,阐释布隆迪外商投资法的基本内容和主要特点。布隆迪外商投资法的法律渊源既包括国内法渊源,即布隆迪先后于1963年8月6日制定的投资法法典,该法典先后经过4次修订,最后一次修订是2008年9月10日,又包括布隆迪政府先后参与缔结或者参加的涉及外商投资的国际条约和双边协定。布隆迪外商投资法具有如下主要特点:第一,赋予外商在布隆迪国内设立企业和货币投资的自由;第二,对外商实行不歧视待遇;第三,签发签证以保障投资者和外籍人士申请居留签证的自由;第四,保证任何自然人或法人的财产所有权不受任何歧视;第五,外商在缴纳税款后,保证外国资本及其收入的自由转移;第六,对外商投资提供系列的政策保护与鼓励。第三部分,剖析布隆迪外商投资法存在的主要问题及其原因。与中华人民共和国外商投资法相比,布隆迪外商投资法至少存在如下问题:第一,外商投资政策缺乏必要的透明度;第二,没有规定在特定时期内给外商特别优惠待遇;第三,没有明确规定外商负有产品出口创汇义务;第四,没有设置合理的外商投资争议的解决机制;第五,缺乏完备的外商投资保险机制。布隆迪外商投资法存在上述主要问题的原因固然是多方面的,但如下原因是不容忽视的:第一,布隆迪对外开放的程度有限;第二,布隆迪的商业环境不佳;第三,人力资本相对较为薄弱。第四部分,重点论述完善布隆迪外商投资法的构想。第一,必须充分立足于本国的国情;第二,使法律框架现代化并与东非共同体(EAC)协调;第三,明确界定外商可以投资尤其是鼓励外商投资的领域;第四,给外商合理的优惠待遇;第五,完善外商投资争议的救济途径;第六,规定有利于外商投资的商业保险制度。从而确保布隆迪外商投资法在吸引外来资金、设备和技术,提升本国的经济实力等诸多方面发挥其应有的作用。

Asphalt concrete pavements in hot and dry climates deteriorate prematurely some time after their construction. This degradation is accelerated under the effect of heavy vehicle traffic pressure and high temperatures after the bitumen has softened. A study was conducted on the RN1 in Burkina Faso in order to analyze the evolution of temperature and traffic in the process of degradation of asphalt concrete pavements. It consisted on the one hand in recording the temperatures at different points inside the layers of asphalt concrete pavements and the layer of laterite. These results were compared with the values of the softening temperatures of the bitumen obtained in the laboratory. On the other hand, this study is supplemented by the daily counting of heavy goods vehicles passing through the RN1 during the month of April in order to study the influence of the evolution of heavy goods vehicle traffic on the degradation of pavements in hot and dry climatic conditions. The results obtained for temperatures and the frequency of heavy goods vehicle traffic favor pavement deterioration under certain conditions.
