Energy storage systems are selected depending on factors such as storage capacity, available power, discharge time, self-discharge, efficiency, or durability. Additional parameters to be considered are safety, cost, feasibility, and environmental aspects. Sodium-based batteries （Na-S, NaNiC12） typically require operation temperatures of 300-350 ~C. The high operating temperatures substantially increase the operating costs and raise safety issues. This updated review describes the state-of-the-art materials for high-temperature sodium batteries and the trends towards the development and optimization of intermediate and low-temperature devices. Recent advances in inorganic solid electrolytes, glass-ceramic electrolytes, and polymer solid electrolytes are of immense importance in all-solid-state sodium batteries. Systems such as Na~ super ionic conductor （NASICON, Nal^xZr2PB-~SixOl2 （0 -〈 x _〈 3））, glass-ceramic 94Na3PS4＂6Na4SiS4, and polyethylene oxide （PEO）-sodium triflate （NaCF3SO3） are also discussed. Room temperature ionic liquids （RTILs） are also included as novel electrolyte solvents. This update discusses the progress of on-going strategies to enhance the conductivity, optimize the electrolyte/electrode interface, and improve the cell design of emerging technologies. This work aims to cover the recent advances in electrode and electrolyte materials for sodium- sulfur and sodium-metal-halide （zeolite battery research Africa project （ZEBRA）） batteries for use at high and intermediate temperatures.

Background With some 134,073,166 people living in endemic communities at risk of infection[1],Nigeria is the most endemic country in Africa and requires preventive chemotherapy(PC)for a total of 26.3 million persons[2].The National Schistosomiasis Elimination Programme(NSCHEP),with the support of international partners,has been implementing PC in Nigeria since 2009 and most recently will need to revise its current strategy(Additional file 1).For example,the new World Health Organization(WHO)guideline has six key recommendations that will dramatically change the implementation of schistosomiasis elimination in endemic countries[3].However,its impact and programmatic implications will vary from country to country,hence the need for a country-specific analysis.

In this work, we obtain good upper bounds for the diameter of any graph in terms of its minimum degree and its order, improving a classical theorem due to Erdos, Pach, Pollack and Tuza. We use these bounds in order to study hyperbolic graphs （in the Gromov sense）. To compute the hyperbolicity constant is an almost intractable problem, thus it is natural to try to bound it in terms of some parameters of the graph. Let H（n, δ0） be the set of graphs G with n vertices and minimum degree 50, and J（n, Δ） be the set of graphs G with n vertices and maximum degree A. We study the four following extremal problems on graphs： a（n,δ0） = min{δ（G）｜ G ∈H（n, δ0）}, b（n, δ0） =- max{δ（G）｜ e ∈H（n, δ0）}, α（n, Δ） = min{δ（G） [ G ∈ J（n, Δ）} and β（n,Δ） = max{δ（G） ] G∈Π（n,Δ）}. In particular, we obtain bounds for b（n, δ0） and we compute the precise value of a（n, δ0）, α（n, Δ） and w（n, Δ） for all values of n, r0 and A, respectively.

在过去的几十年里,随着人口的增长,为人类提供足够的食物和减少全球环境污染成为两个关键问题。类似的,作物的产量会因为水的短缺或者过多,以及极端温度、营养供应不足、病虫草害等非生物和生物胁迫的因素而大幅度的减少。尽管化学农药对于大幅度提高作物产量至关重要,但化学农药的大规模过度使用已导致严重的环境和人类健康问题,并出现了对这些杀虫剂具有抗药性的农业害虫。作物遗传的改变导致有害生物、除草剂抗性产生,这引发了一些担忧。例如,间接地导致了除草剂的使用增多,害虫的抗药性增强,对人类健康也造成多种不利的影响。化学农药和遗传育种最有效的替代办法是生物防治。它包括利用捕食天敌、寄生虫和病原体控制害虫,利用食草动物和病原体管理杂草,利用拮抗微生物和诱导植物抗病性来控制植物病害。生物防治也可以分为生物制剂和非生物制剂。生物型的生防因子由活的细菌、真菌和病毒组成,它们通过拮抗,维生素和生态位的竞争,阻止病原菌在寄主组织中定殖、诱导植物抗病性等多种作用机制对微生物病原菌产生抑制作用。生防细菌在抑制微生物植物病原体的生长和减轻由病原物引起的病害上更加有效。然而,与生防真菌相比,生防细菌在形态特征上变化较小。因此,需要多种生化、生理、免疫和核酸的方法,来分离和鉴定生防细菌。另一方面,非生物的生防因子来源于各种有机和无机途径。同样,它们也被用于土壤、种子、花卉和农作物中,以减少由微生物病原体引起的疾病发病率和减轻病害严重程度。此外有机添加物如堆肥、绿色肥料和蔬菜废弃物可能还包含有害生物,也使用一些非生物的生防因子来进行处理。水稻稻瘟病菌是造成全球水稻产量严重损失的病原菌之一。本研究旨在利用细菌对水稻稻瘟病菌进行生物防治。在中国和世界其他各水稻种植区,稻瘟病是频繁发生的严重问题。因此,一些农民使用抗真菌农药和植物抗病品种来减少稻瘟病造成的损失。然而,由于稻瘟病遗传的复杂性,生理小种可以进化并产生抗药性和克服水稻品种抗性。此外,由于其复杂的遗传背景,通过种植抗病水稻品种来控制稻瘟病具有一定挑战性。植物生境微生物可能对植物造成有害的或有利的影响,例如可以通过竞争、保护或拮抗植物病原物来抑制病害。也就是说,来自植物表面、土壤和根际的各种拮抗微生物已被广泛用于控制一些重要的作物病害。水稻稻瘟病是导致全球水稻作物产量损失的一个重要原因。水稻稻瘟病菌以其特有的黑色圆顶形附着胞而闻名,附着胞中含有紧密的黑色素层。黑色素层对于稻瘟病菌危害水稻是相当重要的,因为它需要产生膨胀压力以启动钉形成,从而破坏植物角质层。各种毒力因子影响病原菌致病性和病害发展中发挥重要作用。由毒力基因编码的一些蛋白质可能参与信号传导,次级代谢,蛋白质失活,防御反应以及分生孢子的产生。稻瘟病菌侵染周期具有明显的发育阶段,第一阶段的特征是三细胞分生孢子附着在水稻叶片的疏水表面,并形成一个极化的胚芽管。第二阶段,该胚芽管进一步分裂成一个膨胀的圆顶形附着胞,开始侵染。第三阶段是由附着胞发育而来的穿透性发育,这种发育取决于各种生态因素,如相互作用表面的疏水性和坚固性,其外源养分的可获得性可以忽略不计。病原菌进一步扩散到邻近的细胞,并且感染的细胞进入坏死营养阶段,其中细丝状次生菌丝最终杀死植物细胞。生防因子和病原体之间的互作已经在水稻和其他经济作物中有大量研究。例如,有研究报道了水稻中真菌和细菌之间的互作,并观察到唐菖蒲伯克霍尔德菌株比黄曲霉菌株具有显著的竞争优势。同样,有研究评估了枯草杆菌和立枯丝核菌之间的相互作用,并观察到芽孢杆菌菌株对真菌菌株有抑制作用。因此,生防菌的开发对于控制植物病害,减轻作物损失是至关重要的。实质上,有必要了解生物防治细菌对植物病原体的全球影响,因为它们可能大大提高全球粮食安全性。因此,本研究旨在阐明枯草芽孢杆菌DL76对稻瘟病菌的生物防治机制。具体而言,本文有两个目标;:（i）评估在枯草芽孢杆菌DL76的影响下稻瘟病菌孢子的萌发和附着胞的形成情况。（ii）检测稻瘟病菌的生长、多重胁迫反应和致病性。我们从稻田中分离出枯草杆菌DL76,并观察到对稻瘟病菌具有较好的抗菌作用。DL76的灭菌培养滤液抑制了稻瘟病菌的生长,我们推断DL76对稻瘟病菌的致病性有一定的影响。因此我们测定了DL76的培养滤液的抗真菌活性。我们观察到在不同浓度（1×10～2、1×10～3、1×10～4、1×10～5、1×10～6、1×10～7CFU/ml）DL76作用下,稻瘟病菌的生长受到显著抑制。制备DL76的灭菌培养滤液并取出70 ml分别置于7个试管中,并调整至不同的p H值。研究在不同的p H下,DL76的抑菌稳定性变化。结果表明,随着p H值增加,抑菌活性明显降低,对应从p H1到p H13,抑菌活性从72.9%降低到5.4%。对DL76热稳定性的研究结果表明,当滤液经4-100℃不

Nanosized magnetite has emerged as an adsorbent of pollutants in water remediation. Nanoadsor- bents include magnetic iron oxide and its modifiers/ stabilizers, such as carbon, silica, clay, organic moieties （polymers, aminoaeids, and fatty acids） and other inorganic oxides. This review is focused on the recent developments on the synthesis and use of magnetic nanoparticles and nanocomposites in the treatment of contaminated water. The emphasis is on the influence of the iron oxide modifiers on some properties of interest such as size, BET area, and magnetization. The characteristics of these nanomaterials are related to their ability to eliminate heavy metal ions and dyes from wastewater. Comparative analysis of the actual literature was performed aiming to present the magnetic material, its preparation methodology and performance in the elimination of the selected pollutants. Vast information has been properly summarized according to the materials, their properties and preferential affinity for selected contaminants. The mechanisms governing nanomaterial＇s formation as well as the interactions with heavy metals and dyes have been carefully analyzed and associated to their efficiency.

Signals of touch,pressure,pain,temperature,position,and vibration are transmitted from the peripheral nervous system（PNS）to the dorsal horn of the segmental spinal cord via pseudounipolar dorsal root ganglia（DRG）*** information gathering relies on functional integrity of DRG neurons and can be interrupted by PNS injury due to trauma,disease or exposure to drugs, toxins or viral pathogens. Despite the high regenerative capacity of DRG neurons, sensory recovery after PNS injury is often incomplete and severe neuropathic pain may last for years. Although numerous mechanisms of PNS injury have been established, neuropathic pain is refractory to therapy, contributing to the physical and emotional suffering of patients and the enormous economic burden to society.
