The basics of mining landslides were first summed up based on the analysis ofactual materials by the application of mining subsidence and landslide theories. Further,the mechanism of along-layer landslide by mining was studied with the example of theXiangshan mining landslide at Hancheng, Shaanxi Province. Meanwhile, the state ofstress, and the mechanism of deformation and destruction of the Xiangshan mining slopewere analyzed by the Finite Element Method. 展开更多

The cashmere yarns were set in steam of 120℃ for 5 minutes after they had been extended to about 3% and wrapped onto the glass mandrels, which was relevant to the industrial setting processes. The effects of the steaming on the tensile mechanical properties of cashmere fiber are investigated. The extension in ' yield region' and the extension at rupture of the set cashmere fiber are obviously decreased. 展开更多

The labor market requires, increasingly, an updated and more professional preparation, mainly due to the rapid pace of scientific technical advancement means in the industry. From this point, it is important to encourage the development of the basic techniques of control systems, electronics and communication in order to produce knowledge in the mechatronic field and so apply them to industry. Considering the relevance of this subject, the students of Federal University of Para-Campus Tucumi through the Research Group of Electrical and Mechanical Systems apply their knowledge in multidisciplinary engineering fields in order to generate knowledge from creative techniques using low cost materials, together with the encouragement of social and environmental responsibility which is very important nowadays. At the same time, targeting the needs of the labor market, this work aims to foster in students the skills and requirements through team projects and innovative methods. Therefore, this paper presents a mechanical manipulator, where their operating characteristics are based on industrial robots in the literature, powered by DC (direct current) motors and fully developed from reusable materials. By adding a developed control from the Arduino, prototyping platform with an electronic strategic offers through the internet the long-distance control convenience. 展开更多

Nuclear power is a powerful and effective energy branch in Ukraine. There are currently 4 active nuclear power stations (NPS) and 13 operational VVER energy units, producing a total power of 11880 MW, in the country. According to the data collected from the International Agency of Nuclear-Power Energy, Ukraine is in seventh place for the largest supply of uranium on the planet. The use of nuclear power in Ukraine includes: extraction and processing uranium ore, production of UF6, production of zirconia rental and purveyances from a zirconia alloy, production of heat-radiating collections, storage of exhaust nuclear fuel and nuclear wastes. The realisation of uranium isotopic enrichment is the main problem in the structure of organisation in nuclear fuel production in Ukraine. This country has a unique station, non-operative Chemobyl NPS, where different types of wastes are located. Two factories are currently being built there in order to process the liquid and solid radio-active wastes. In perspective, Ukrainian nuclear-power energy will be enriched with new nuclear-power units and security systems to ensure safe manufacturing. 展开更多

The price of fuel oil continues to rise, decreased supplies oil at the other side, both factors increase the interest of researchers to conduct research related to fuel efficiency. Therefore the aim of this study is to improve the efficiency fuel of diesel engine using fuel filter. The method used for the research is testing the most efficient fuel filters made of coil wire coil winding 5,000, the three distinguished from the coil core diameter of 44.5, 28.5 and 17.5 mm in diesel engine. The performance test was conducted from 1,100 rpm to 1,700 rpm, the throttle opening of 30%-60%. The first testing was done by creating a constant speed 1,500 rpm and throttle opening varies from 30% to 60%, further testing is done by varying the rpm start from 1,100 rpm to 1,700 rpm to make constant valve 40% and 60%. 展开更多

Recently, photothermal therapy (PTT) has attracted tremendous attention because of its high efficacy in tumor ablation and minimal damage to normal tissues. While many inorganic nanomaterials, especially various gold nanostructures and nanocarbons, have been extensively explored for near-infrared (NIR) light triggered PTT in the past decade, a variety of organic photothermal agents have also emerged in recent years, aiming at replacing their inorganic counterparts which usually are not biodegradable. In this mini-review, we will summarize several typical classes of recently developed NIR-absorbing organic PTT nano- agents, which include NIR dye-containing micelles, porphysomes, protein-based agents, conjugated polymers, and organic/inorganic nanocomposites. The development of imaging-guided PTT and combination therapy will be introduced as well. Finally, the perspectives and challenges in the future development of PTT will be discussed. 展开更多

Optic-electric responsive materials have attracted much attention for their applications in temperaturesensing,actuators,and memory switches.However,it is a challenge to integrate various functions to form multifunctional responsive materials.As molecule-based hybrid materials usually consist of organic and inorganic components,the introduction of multiple functions can be achieved through structural construction.Thus far,even though fulltemperature cover is required for device applications,fulltemperature covered multi-switchable hybrid materials have rarely been successfully synthesized.Herein,the dynamic[(CH3)3NOH]+cation and luminous center Mn(II)were introduced to form a hybrid material[(CH3)3NOH][Mn Cl3],showing multiple temperature-responsive behaviors.Upon temperature change,it exhibits multi-state dielectric switching response and intensity or peak shift response of luminous in full-temperature range(low,room,and high temperatures).These responsive behaviors are triggered by the motion or reorientation of[(CH3)3NOH]+cations and inorganic framework.Overall,the switchable photoelectric material has potential applications in multiple encrypted storage and sensor devices. 展开更多
