An estimated one-third of water points in rural sub-Saharan Africa are non-functioning at any one time because of lack of upkeep. Communities are left without access to clean drinking water and this has multiple knock-on developmental impacts. An innovative pre-payment and Internet-of-Things enabled “e-Tap” based water technology and management system cycles revenue back into operation and maintenance and collects accurate and real-time data on consumption and tap failures. This has been operational in the Gambia since April 2016. Preliminary research has begun on evaluating this innovation. Technical tests were conducted to examine the efficiency of the e-Tap under varying conditions. Water use trends were then analysed by using the cloud-collected data transmitted from operational e-Taps. Further, baseline sveys to investigate social parameters were undertaken on 20 user households. This exploratory research shows the e-Taps to work efficiently in the laboratory and the Gambia with negligible failures, and to reduce distances users must travel for clean water and time they spend collecting.

Whilst there have been several definitions of Evidence-Based Medicine (EBM), the one given by David Sackett is probably the most accurate and well accepted; he stated that "evidence-based medicine is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients"[1].

Matthew Kurien及其同事撰写文章提出无麸质食品处方可改善乳糜泻患者预后，但JamesCave则抨击这一昂贵的供应系统可能使患者和医生均感到失望。正方——Matthew Kurien,Sarah Sleet，David Sanders由于近三分之二的信托机构存在赤字，英国国家健康体系（NHS）正面临着前所未有的财政和运营压力。英国医疗保健支出占国内生产总值的比例目前低于其他西欧邻国，这更加剧了上述压力。政府通过责令医疗专业人员提高生产力、工作效率和分配制度来恢复财政平衡。

核酸技术作为监测和鉴定病原的第一步正在被广泛使用,PCR 发展到新一代 PCR 产物 RT-PCR,它是一种在试验进行中可以看得见的反应。在 PCR 作为诊断技术主流的同时,建立在核酸基础上的新一代诊断技术正在形成,如检测遗传物质的环介导扩增技术(LAMP)和基因芯片技术。当人们对有兴趣的病原在实验室不能(不容易)分离和生长的时候,核酸鉴定技术的价值就提升了。本文描述了我们使用 RT-PCR 研究火鸡冠状病毒和火鸡星状病毒的情况,组织培养系统不适合这两种病毒的检测。幸运的是：火鸡冠状病毒和传染性支气管炎病毒(IBV)一样,其基因序列已经被测定,用于测定 IBV 的 RT-PCR 被成功地应用于火鸡冠状病毒。类似的结果,哺乳动物和禽类的星状病毒在基因1上面有一些保守序列,使得能够设计潘-星状病毒的核苷酸引物。我们检测的结果表明,火鸡感染火鸡冠状病毒和火鸡星状病毒的感染率分别为52%和70%,可见这两种病毒的感染非常普遍。在一个腹泻症状特别严重的火鸡群,其死亡率超过20%,两种病毒都被检测到,此外,也检测到了肠道致病性大肠杆菌。环介导扩增技术(LAMP)是一项比 PCR 更具活力的方法,它需要便宜简单的仪器,结果用裸眼可以判定：如果病毒存在则液体改变颜色。在野外就可以使用这种方法。核酸芯片技术用单一操作可以检测数百种或数千种病原/菌株,在不知道病原(或多种病原混合感染)的情况下,这种方法特别有用,它可以确诊疫病,包括有多少种新的病原。本文中描述了我们拥有的3000个核苷酸芯片和 IBV 感染细胞。

1 Introduction As wireless technology continues to expand,there is a growing concern about the efficient use of spectrum *** though a significant portion of the spectrum is allocated to licensed primary users(PUs),studies indicate that their actual utilization is often limited to between 5%to 10%[1].The underutilization of spectrum has given rise to cognitive radio(CR)technology,which allows secondary users(SUs)to opportunistically access these underused resources[2].However,wideband spectrum sensing,the key of CR,is limited by the need for high-speed analog-to-digital converters(ADCs),which are costly and *** spectrum sensing(CSS)addresses this challenge by employing sub-Nyquist rate *** efficiency of active transmission detection heavily depends on the quality of spectrum reconstruction.

为解释绵羊对大片吸虫(Fasciola. gigantica)较对肝片吸虫(F. hepatica)不易感的原因,本研究比较了绵羊感染肝片吸虫(H组)和大片吸虫(G组)后细胞免疫应答的特性。结果表明,绵羊感染大片吸虫后嗜酸性粒细胞数量快速明显升高。两组绵羊的外周血单核细胞(PBMC)经两种吸虫的分泌排泄抗原(ESP)刺激后的增殖情况相似。受刺激的PBMC产生的IFNγ水平均在感染后第1周(1 WPI)达到峰值,但H组中,FhESP刺激产生的IFNγ水平低干FgESP刺激所产生的水平。H组中IL-10的产量没有明显的增加:因为从0 WPI开始IL-10水平就很高。整个感染过程中,FhESP刺激后H组和G组产生的IL-10水平都很高,但受FgESP的刺激下的PBMC所产生的IL-10水平只在1-5 WPI上升。在G组,FhESP刺激比FgESP刺激产生更多的IL-10。综合上述结果,绵羊对大片吸虫较不易感的原因与虫体感染后诱导机体产生强烈的细胞免疫应答和大片吸虫逃避宿主免疫应答的能力较弱有关。

1 Introduction The fact that the spectrum resource is underutilised in certain bands has motivated the dynamic spectrum access(DSA)approach,which enables unlicensed secondary users(SUs)equipped with cognitive radio(CR)devices to access the spectrum without causing significant interference to primary users(PUs).Nowadays,the increasing bandwidth for wireless communication in millimetre-wave and Terahertz frequency bands puts higher requirements on the performance of spectrum sensing technique,the primary enabler of DSA.
