An important problem associated with the progression of aging in society is the improvement of quality of life (QOL). If we can maintain or improve the QOL for individuals, including the elderly, this will contribute not only to the revitalization and stability of society [1], but also to the reduction of social costs such as nursing care and medical expenses [2]. Therefore, a living support system, such as an acceptable living environment and health monitoring system, is required. There are currently no imaging systems capable of automatically and quantitatively evaluating the factors that improve individual QOL and the intensity thereof in real time. Human QOL and "laughs/smiles" are closely related. Individuals who laugh every day exhibit better health and improved psychological state. In addition, calmness is recognized in animal-assisted therapy and is known to contribute to the improvement of QOL [3]. Based on these fi ndings, it is considered that maintaining or improving QOL is possible in an environment where amusement and calm are encouraged. Using visual images, it is difficult to distinguish between natural facial expressions and those shown intentionally; however, there is no example for defining and observing calmness [4]. The report on emotions by Miyasaka et al. focused on changes in facial skin temperature and accompanying blood fl ow [5] with emphasis on nose temperature, while Kumamoto et al. reported on a method for evaluating stress [6]. There is no system that considers an example of integrated visible and infrared images to evaluate attitude changes. In our previous studies, we showed that movement features of the lip change as the subject's feelings (state of no stress, no vision, etc.,) and physical conditions change, while acquiring motion data on the movement of the lips. We clarifi ed that the presence or absence of psychological changes can be discriminated by the movement features of the lip when amusement is evoked [7]. Vertical motion was observed in the head and shoulders when a strong emotion such as "amusement" was expressed. Nonverbal communication, including body movements, contributes to the transmission of approximately 65% of information [8]. That is, combining facial expression, movement features of the lips, and movement features of the body is useful for the recognition and quantification of emotions. In this paper, we develop elementary technologies of multiimage processing systems that can recognize multiple emotions by focusing on the basic study of body movement features to recognize emotion. This study aims to verify whether emotions of amusement can be detected with body movement features by using Microsoft Kinect. Although there are individual differences, this study aims to demonstrate the possibility of using body movement features as indicators of the strength of emotional expressions.

与社会老龄化进程相关的一个重要问题是生活质量(QOL)的提高。如果我们能够保持或提高包括老年人在内的个人的生活质量，这不仅有助于社会的振兴和稳定[1]，而且有助于降低护理和医疗费用等社会成本[2]。因此，需要一个生活支持系统，如可接受的生活环境和健康监测系统。目前还没有成像系统能够自动和定量地实时评估改善个人生活质量的因素及其强度。人类的生活质量和“笑/微笑”是密切相关的。每天笑的人身体更健康，心理状态也更好。此外，镇静在动物辅助治疗中得到认可，并有助于改善生活质量[3]。基于这些发现，我们认为在一个鼓励娱乐和平静的环境中，维持或改善生活质量是可能的。使用视觉图像，很难区分自然的面部表情和故意表现的面部表情;然而，并没有定义和观察平静的例子[4]。Miyasaka等人关于情绪的报告关注面部皮肤温度和伴随的血流变化[5]，重点关注鼻子温度，而Kumamoto等人则报道了一种评估压力的方法[6]。目前还没有一种系统可以考虑综合可见光和红外图像的例子来评估姿态变化。在我们之前的研究中，我们发现嘴唇的运动特征随着受试者的感觉(无压力、无视觉等状态)和身体状况的变化而变化，同时获取嘴唇运动的运动数据。我们阐明了心理变化的存在与否可以通过引起娱乐时嘴唇的运动特征来区分[7]。当表达强烈的情感，如“娱乐”时，可以观察到头部和肩部的垂直运动。包括肢体动作在内的非语言交际约占信息传递的65%[8]。也就是说，结合面部表情、嘴唇的运动特征和身体的运动特征，对情绪的识别和量化是有用的。本文通过对人体运动特征识别情绪的基础研究，开发了能够识别多种情绪的多图像处理系统的基本技术。本研究旨在验证是否可以使用微软Kinect通过身体运动特征来检测娱乐情绪。尽管存在个体差异，但本研究旨在证明使用身体运动特征作为情绪表达强度指标的可能性。具体来说，我们使用了XBOX ONE KINECT传感器(微软公司，简称KINECT)，它专注于非语言信息，如身体运动，以及在观看情感引发视频时以非接触方式进行的人类运动[9]。我们获得了受试者在观看引发情绪的视频时头部和肩部运动的三维数据，并对娱乐和平静进行了量化研究。在本文中，我们通过多种方法，使用来自多个被试的数据来检验“娱乐”情绪与身体动作之间的相关性。基于肢体动作三维数据的娱乐情绪识别

were still in the glass case. The stainless steel rod electrodes that had been fi lm-coated by insulating spray were inserted into the food interior to measure the impedance of the surface, upper, middle, and the lower regions of the food (Figure 1). After sprinkling various amounts of NaCl all over the gel surfaces, the impedance values of gels were measured using an Inductance Capacitance and Residence (LCR) meter (3523-50; Hioki E. E. Corp., Japan). The sample impedance For this study, we developed a novel real-time monitoring system using a stainless steel electrode to assess NaCl osmosis in the food interior by measuring electrical impedance. The NaCl penetration into agar gel sprayed with NaCl on the surface was evaluated using impedance. As the measured position of the electrode moves downward, a longer time is needed to obtain a constant impedance value. Measurement of the chloride concentrations in the model food that had been cut into four pieces (surface, upper, middle, and lower parts) revealed an extremely strong relation between the equilibrium period of the impedance value and the inner chloride concentrations of the model. Results con fi rmed that a similar impedance value was obtained if the concentration of NaCl sprinkled on the top of the gels was the same irrespective of points measured using the electrode. These results demonstrate that this impedance measurement method using an LCR meter is useful for real-time monitoring of NaCl osmosis in the food interior.

Copper porphyry the world and very of copper, silver and gold. These deposits initially consist of disseminated sulfide minerals in a rock matrix, but near-surface weathering oxidizes the sul fi des and dissolves metals from the residual mass. These leached metals in solution percolate downward and are often reprecipitated in an enrichment zone overlying unreacted sulfide protore. The near-surface weathered, oxidized portion of the deposit corresponds to the oxidized region (high oxidation potential), while the non-oxidizing reduced enrichment zone corresponds to the reduced Copper sul fi de from ore deposits and recycled copper from collected wastes are the two main resources for the production of copper metal. Thermodynamic calculations can be used to serve as a guide for characterization of ore deposits and their mineralogy as well as for process development by mineral processing and by waste separation. The concentrated ore and separated waste can then be processed by pyro- and/or by hydro-metallurgical operations. Such operations may be controlled by oxidation-reduction potential, temperature, complexing reagents (gas, solid or dissolved species), oxidant- reductant, and mass of components. Commonly used stab ility diagrams for aqueous system include speciation (counting alpha) and E H -pH (Pourbaix) diagrams and, for non-aqueous systems, are partial pressure (Kellogg), binary and ternary phase, and Ellingham diagrams. For multicomponent systems, the appropriate approach for the construction of the stability diagram is to use a complete mass balance approach rather than draw the equilibrium line between two adjacent species. Not limited to two variables, a three- dimensional diagram can also be constructed. This paper illustrates the use of stability diagrams for investigating and interpreting how operation variables are important with a focus on extractive metallurgical operations to produce copper. Industria l operation conditions are marked on the diagrams.
铜斑岩世界上盛产铜、银、金。这些矿床最初是由浸染在岩石基质中的硫化物矿物组成的，但近地表的风化作用氧化了硫化物，并从残余的物质中溶解了金属。这些浸出的金属在溶液中向下渗透，并经常在未反应的硫化物原矿上的富集带中再沉淀。矿床的近地表风化氧化部分对应于氧化区(高氧化电位)，而非氧化还原富集区对应于矿床中还原的硫酸铜和回收废物中的再生铜是生产铜金属的两个主要资源。热力学计算可用作矿床特征及其矿物学的指南，并可用于矿物加工和废物分离的工艺发展。然后，浓缩的矿石和分离的废物可以通过热法和/或湿法冶金操作进行处理。这些操作可以通过氧化还原电位、温度、络合试剂(气体、固体或溶解物质)、氧化剂-还原剂和组分的质量来控制。对于水系统，常用的刺痛性图包括形态图(计数alpha)和E - H -pH图(Pourbaix)，对于非水系统，常用的刺痛性图包括分压图(Kellogg)、二相和三元相图以及Ellingham图。对于多组分系统，构建稳定性图的适当方法是使用完整的质量平衡方法，而不是在相邻的两个组分之间绘制平衡线。不仅限于两个变量，还可以构造三维图。本文说明了使用稳定性图来调查和解释操作变量是如何重要的，重点是提取冶金操作，以生产铜。工业操作条件在图表上作了标记。。

Waste asphalt blocks from construction sites are usually processed in the recycling plants to be used as recycled asphalt aggregates. These materials are usually fed into the grizzly to remove the soils attached on their surfaces. At present, grizzly-under-materials (GUM) does not satisfy the required standard value for soil contents. In 2009, we proposed the equipment to remove the soils from GUM. This equipment was able to reduce the soil content in the GUM, but the ef fi ciency was not so high. Then, in 2013, a process of re-designing this equipment was carried out; where a vibration device was added to reduce the pipe inclination angle and to increase the processing time of materials inside the apparatus. The equipment performance had an opposite behavior from 2009 ’ s experimental results to 2013 ’ s experiment results, when the water content in the GUM was changed from 3% to 5%. That is, it was necessary to analyze the main factors that in fl uence on equipment performance. In this study, the experiments were carried out with changing the water contents. It was found through this research that soil reduction activity, using the screenless separation equipment not only depends on the soil particle distribution (% of clay and silt) contained in GUM and the moisture content in the soil when is mixed with GUM. Speci fi c surface area and water absorption of GUM and temperature also have in fl uence on the mentioned activity.

We have already established the Fiber-Cement-Stabilized Soil Method that can improve the weak soil of actual landslide areas engendered from an earthquake or heavy rainfall by using paper fragments and cement. However, nowadays, the cost of fi ber (paper debris) is tending to increase and Portland cement is not environmentally friendly cementitious material for sustainable development. In this research, Geopolymer which expects to modify soft soil (sludge) at low degree Celsius condition and reduces amount additive of fi ber is executed. The process of Geopolymerization involving the silicates and aluminates exacted from by-products is contemplated as a mature and cost-effective solution to many problems where hazardous residue has to be treated and stored under critical environmental conditions. This paper presents the details of the study carried out on the characteristic of sludge improved Fiber-Geopolymer-Stabilized Soil Method. The composition of imitation sludge was 60% silt, 40% clay and 70% water content. Sodium hydroxide (NaOH) 12 Molar and sodium silicate solution (Na 2 SiO 3 ) were prepared. The test specimens were made of 50 x 100 mm cylindrical mold and 20 ℃ temperature curing condition. The result of modified sludge shows the improvement in strength, strain and high durability with drying and wetting tests regardless of the increase in experimenting rounds.

The Kroll Institute for Extractive Metallurgy, KIEM, was established in 1974 at the Colorado School of Mines in accordance with a bequest from William J. Kroll, world renowned extractive metallurgist best known for his inventions of processes for the production of titanium and zirconium. The fi nancial resources of Dr. Kroll’s bequest were intended to provide for the establishment of a Center for Excellence in Extractive Metallurgy at the Colorado School of Mines. Since its inception, the Kroll Institute has provided financial support to both undergraduate and graduate students at CSM, many of whom, subsequently, have made important contributions, nationally and internationally, to the fi elds of mining, minerals, metals and advanced materials. Today, the mission of the Kroll Institute is to support the minerals, metals and materials industries through the following activities: The academic environment creates a unique opportunity Globally, Critical Metals have become a focus in many countries and jurisdictions. While the primary production of Rare Earths has been highlighted, other less known but even more Critical Metals from primary and secondary sources have also been studied. At the Kroll Institute for Extractive Metallurgy, KIEM, much of the research effort is currently focused upon either the primary or secondary production of Critical Metals. In addition, the key underlying aspect of Criticality is also being addressed in the form of the development of desperately needed technically skilled personnel and technologies which are increasingly in demand. This paper will outline aspects of these topics.
克罗尔冶金研究所(KIEM)于1974年在科罗拉多矿业学院成立，根据世界著名的冶金学家威廉·j·克罗尔(William J. Kroll)的遗赠，他以发明钛和锆的生产工艺而闻名。Kroll博士遗赠的财政资源是为了在科罗拉多矿业学院建立一个卓越的采掘冶金中心。自成立以来，克罗尔研究所为CSM的本科生和研究生提供了经济支持，其中许多人随后在国内和国际上为采矿、矿物、金属和先进材料领域做出了重要贡献。今天，克罗尔研究所的使命是通过以下活动为矿产、金属和材料行业提供支持:学术环境创造了独特的机会在全球范围内，关键金属已成为许多国家和司法管辖区的焦点。在强调稀土的主要生产的同时，人们还研究了来自主要和次要来源的其他不太为人所知但更为关键的金属。在克罗尔提炼冶金研究所(KIEM)，目前的大部分研究工作集中在关键金属的初级或二级生产上。此外，还以发展迫切需要的技术熟练人员和需求日益增加的技术的形式处理临界性的关键基本方面。本文将概述这些主题的各个方面。

Since its inception, the Kroll Institute has provided financial support to both undergraduate and graduate students at CSM, many of whom, subsequently, have made important contributions, nationally and internationally, to the fi elds of mining, minerals, metals and advanced materials. Today, the mission of the Kroll Institute is to support the minerals, metals and materials industries through the following activities: The academic environment creates a unique opportunity Globally, Critical Metals have become a focus in many countries and jurisdictions. While the primary production of Rare Earths has been highlighted, other less known but even more Critical Metals from primary and secondary sources have also been studied. At the Kroll Institute for Extractive Metallurgy, KIEM, much of the research effort is currently focused upon either the primary or secondary production of Critical Metals. In addition, the key underlying aspect of Criticality is also being addressed in the form of the development of desperately needed technically skilled personnel and technologies which are increasingly in demand. This paper will outline aspects of these topics.","PeriodicalId":14339,"journal":{"name":"International journal of the Society of Materials Engineering for Resources","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74008823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
