Electrical conductivity of molten slag is an important physicochemical property for designing the refming process in electric smelting furnaces. Though conductivities of many slag systems have been measured, the quantitative relationships of conductivity with slag composition and temperature are still very limited. In this article, the Arrhenius law was used to describe the experimental data of conductivities for CaO-MgO-Al2O3-SiO2, CaO-Al2O3-SiO2, CaO-MnO-AlEO3-SiO2, as well as CaO-MgO-MnO- Al2O3-SiO： systems, and it is found that activation energy can be expressed as a linear function of the content of components, where the optical basicity of slag must be within the range of 0.58 to 0.68.

背景:金属有机骨架(metal-organic frameworks,MOFs)是一种由金属节点和有机配体组成的新型多孔材料。部分MOFs自身即具备光热转化能力或光动力效应,亦可作为载体负载光热剂或光敏剂,在激光诱导下产生活性氧或升高温度发挥光疗作用,被广泛应用于抗菌及抗肿瘤等生物医学领域。当MOFs同时具有这两种光疗作用时,可发挥协同治疗的效应,以弥补单独使用一种光疗方法的不足。目的:按照不同的结构总结目前提出的MOFs光热/光动力联合治疗策略,以期为联合治疗材料MOFs的结构设计、功能负载及临床应用场景提供新的思路。方法:以“金属有机骨架/金属有机框架,光动力治疗,光热治疗”为中文检索词,“Metal-organic frameworks,photodynamic therapy,photothermal therapy,phototherapy”为英文检索词,检索了PubMed、Web of Science、ScienceDirect、中国知网和万方数据库的文献,最终纳入76篇进行综述分析。结果与结论:①光热/光动力联合治疗可发挥相互增强的协同作用。②现有光热/光动力联合治疗策略主要包括了改性MOFs骨架赋予其光热、光动力效应,将光疗剂封装于MOFs,光疗剂与MOFs形成核壳结构,光疗剂在MOFs内原位还原,将光疗剂附着于MOFs表面以及热解MOFs以形成MOFs衍生的碳材料等其他特殊改性方法。③要构建特定的光疗MOFs结构,必须综合考虑光疗剂和MOFs的种类、尺寸、结合方式,选择不同的合成策略。封装结构合成过程简单,但仅适用于小粒径光疗剂;核壳结构稳定,但合成过程繁复;原位还原对光疗剂尺寸无特殊限制,但难以精确控制光疗剂在MOFs内部的生长;表面附着结构的合成步骤简便,但不能避免光疗剂提前聚集猝灭;热解MOFs合成条件要求高,且只有特定的MOFs才能实现。④现有的光热/光动力联合治疗策略主要被应用于抗菌、抗肿瘤治疗并表现出优异性能,具体的应用领域与光疗剂和MOFs自身的性质有关,还有部分用于类风湿性关节炎、抗凝溶栓治疗,其潜在应用场景十分广阔。⑤光热剂和光敏剂的临床转化目前仍处于起步阶段,其面临的关键挑战包括生物安全性评估激光照射参数的优化以及高效大规模合成方法的开发。

In this study, a full-color emission red–green–blue(RGB) quantum-dot(QD)-based micro-light-emitting-diode(micro-LED) array with the reduced optical cross-talk effect by a photoresist mold has been demonstrated. The UV micro-LED array is used as an efficient excitation source for the QDs. The aerosol jet technique provides a narrow linewidth on the micrometer scale for a precise jet of QDs on the micro-LEDs. To reduce the optical cross-talk effect,a simple lithography method and photoresist are used to fabricate the mold, which consists of a window for QD jetting and a blocking wall for cross-talk reduction. The cross-talk effect of the well-confined QDs in the window is confirmed by a fluorescence microscope, which shows clear separation between QD pixels. A distributed Bragg reflector is covered on the micro-LED array and the QDs' jetted mold to further increase the reuse of UV *** enhanced light emission of the QDs is 5%, 32%, and 23% for blue, green, and red QDs, respectively.

AIM: To determine changes in the antibiotic resistance of Helicobacter pylori(H. pylori) in southern Taiwan after failure of first-line standard triple ***: We analyzed 137 H. pylori-infected isolates from patients who experienced eradication failure after standard first-line triple therapy from January2010 to December 2014. The H. pylori strains were tested for susceptibility to amoxicillin, clarithromycin,levofloxacin, metronidazole and tetracycline using the E-test method. The minimal inhibitory concentration(MIC) was determined by the agar dilution *** values of ≥ 0.5, ≥ 1, ≥ 1, ≥ 4 and ≥ 8 mg/L were considered to be the resistance breakpoints for amoxicillin, clarithromycin, levofloxacin, tetracycline and metronidazole, ***: A high resistance rate was found for clarithromycin(65%-75%) and metronidazole(30%-40%)among patients who failed first-line standard *** resistance levels to amoxicillin and tetracycline remained very low; however, levofloxacin resistance was as high as 37.5% in 2010 but did not increase any further during the past 5 years. The rates of resistance to these antibiotics did not show a statistically significant upward or downward ***: Antibiotic resistance of H. pylori remains a problem for the effective eradication of this pathogen and its associated diseases in Taiwan. High clarithromycin resistance indicated that this antibiotic should not be prescribed as a second-line H. pylori eradication therapy. Moreover, levofloxacin-based second-line therapy should be used cautiously, and the local resistance rates should be carefully monitored.

This study presents a three-point method for separating incident and reflected waves to explain normally incident waves' propagating over a sloping bed. linear wave shoaling is used to determine changes in wave amplitude and phase in response to variations of bathymetry. The wave reflection coefficient and incident amplitude are estimated from wave heights measured at three fixed wave gauges with unequal spacing. Sensitivity analysis demonstrates that the proposed method can predict the reflection and amplitude of waves over a sloping bed more accurately than the two-point method.

In this paper, we investigate the existence, uniqueness and the asymptotic equiv- alence of a linear system and a perturbed system of differential equations with piecewise alternately advanced and retarded argument of generalized type （DEPCAG）. This is based in the study of an equivalent integral equation with Cauchy and Green matrices type and in a solution of a DEPCAG integral inequality of Gronwall type. Several examples are also given to show the feasibility of results.
