Background:As a neglected cross-species parasitic disease transmitted between canines and livestock,echinococcosis remains a global public health concern with a heavy disease *** China,especially in the epidemic pastoral communities on the Qinghai-Tibet Plateau,the harsh climate,low socio-economic status,poor overall hygiene,and remote and insufficient access to all owned dogs exacerbate the difficulty in implementing the ambitious control programme for *** aimed to design and implement a remote management system(RMS)based on internet of things(loT)for control and surveillance of echinococcosis by combining deworming devices to realise long-distance smart deworming control,smooth statistical analysis and result *** methods and tools are urgently needed to increase the deworming coverage and frequency,promote real-time scientific surveillance,and prevent transmission of echinococcosis in remoted transmission areas.

Transition metal-based nanomaterials have emerged as promising electrocatalysts for oxygen evolution reaction（OER）. Considerable research efforts have shown that self-reconstruction occurs on these nanomaterials under operating conditions of OER process. However, most of them undergo incomplete reconstruction with limited thickness of reconstruction layer, leading to low component utilization and arduous exploration of real catalytic mechanism. Herein, we identify the dynamic behaviors in complete reconstruction of Co-based complexes during OER. The hollow phytic acid（PA） cross-linked CoFe-based complex nanoboxes with porous nanowalls are designed because of their good electrolyte penetration and mass transport ability, in favor of the fast and complete reconstruction. A series of experiment characterizations demonstrate that the reconstruction process includes the fast substitution of PA by OH-to form Co（Fe）(OH)xand subsequent potential-driven oxidation to Co（Fe）OOH. The obtained CoFeOOH delivers a low overpotential of 290 mV at a current density of 10 mA cm-2and a long-term *** experiment results together with theory calculations reveal that the Fe incorporation can result in the electron rearrangement of reconstructed CoFeOOH and optimization of their electronic structure,accounting for the enhanced OER activity. The work provides new insights into complete reconstruction of metal-based complexes during OER and offers guidelines for rational design of high-performance electrocatalysts.

A large number of new varieties, especially hybrid rice, have been developed and released in China since 1998. The yield potential and grain quality of hybrid rice have also been improved significantly both for three-line and two-line hybrid rice including indica and japonica types as well. The trends on extension of rice varieties in China since 1986 has been marked by the increasing number of new varieties, decreasing annual planting area per variety, decreasing number of varieties with a large-scale extension area, while both the renewal rate and the proportion of core varieties with cross-provincial extension have remained unchanged. This current major problems and future goals of rice breeding and extension in China were also discussed.

The present paper covers a salt of 2:18 heteropoly complex of tungstotitanophosphate prepared with the method of improved sequence preparation. The title compound was characterized by elemental analysis, 31P NMR spectra, polarography, cyclic voltammetry, IR, UV, X-ray powder diffraction , X-ray photoelectron spectra and TG-DTA analysis. The results show that the complex with the formula K8[TiP2W17O62]·12H2O has Dawson structure. Its properties such as spectra, redox behavior and thermal stability are discussed.

为研究高温状态砂岩力学特征和水泥浆对高温状态砂岩力学性质的影响,对高温状态砂岩和水泥浆处理后高温砂岩进行单轴压缩试验。试验结果表明:随温度升高,试样表现为裂隙发育,脆弱区范围增大,全程应力-应变曲线时间短,最大应变值减小趋势,极限抵抗强度降低;水泥浆浸泡过的高温砂岩相比高温状态砂岩,裂隙密度减小,结构密度增大,应变趋势减缓,形成极限破坏时间较长最大应变值增大,说明水泥浆改善了高温砂岩变弱趋势,为未来绿色矿山边坡稳定治理提供参考。
