In recent years, three-dimensional computer graphics (3DCG) technology has been applied in various fields. One problem with this technique is the problem of contact between clothing and other objects (such as the body). In this paper, we verified simple animations concerning of hula costumes using three calculation methods, and found that we were able to create simple and stable animations using the FB Euler method. This paper reports that we were able to create a simple animation.

In 2016, we conducted a survey of high school students regarding science classes, and found that the percentage of high school students who answered that they "like science" or "science is important" was lower than for other subjects. However, more than 80% of elementary and junior high school students answered that they ``like experiments and observations.'' Additionally, a 2019 smartphone penetration rate survey found that approximately 90% of students use smartphones. Additionally, recent advances in VR technology have been remarkable. Based on the above, I thought that creating a simulation app using VR technology using smartphones could change the way high school students think about science classes. In this paper, we developed a new simulation application for science experiments. The subjects were asked to experience the newly created app and answer a questionnaire. The average score was 4 out of 5, which was poor. However, a problem was also discovered at the same time. The problem is that this app is a simulation app, so the user experience is not very good, so I would like to develop an app that is a little more user-friendly in the future. I would like to create apps for other fields while improving the problem.

There are 25 species of bioluminescent fungi that have been confirmed in Japan, and 12 species have been confirmed in Miyazaki Prefecture. Those fungi are very small. Therefore, it is difficult to observe the structure of fungi exhibited in museums with the naked eye. The purpose of this research is to display 3DCG models of mushrooms using AR (Augmented Reality) technology in order to facilitate observation of these small mushrooms exhibited in museums. Two hundred visitors to the museum were asked to use the application and complete a survey. In order to measure the ease of observation of different app functions and mobile devices used in the survey, we divided the respondents into four groups.

Arsenic(As) and selenium(Se) has become an increasingly serious water contamination worldwide, so the development of adsorbents to improve the adsorption performance of As and Se oxyanions is desired. In this study, NiZn adsorbents intercalated acetate, chloride, nitrate, and sulfate anions to interlayers of NiZn hydroxy double salts were prepared and their adsorption behavior of As and Se oxyanions was investigated. The Langmuir isotherm model, characteristic of monolayer adsorption, fit the experimental data well with R2 >0.94. The adsorption capacity(qmax) of Se(IV) was the other NiZn-AcO ≈ NiZn-Cl > NiZn-NO3 > NiZn-SO4 and that of Se(VI) was the order of NiZn-Cl > NiZn-AcO > NiZn-NO3 > NiZn-SO4. The qmax of as(V) on NiZn-Cl was about twice as large as that on NiZn-AcO, NiZn-NO3 and NiZn-SO4. NiZn-Cl was found to adsorb As(V) and Se(VI) oxyanions more efficient than NiZn-AcO.

Miyazaki Prefecture is blessed with the rich nature of the Kyushu Mountains, where many mushrooms have grown wild since ancient times, and the production of dried shiitake mushrooms ranks second in Japan after Oita Prefecture. SUGIMOTO Co., Ltd., which will be cooperating with us this time, is a long-established company established in 1970, and at times it is necessary to sort over 1 ton. However, since selection is still done manually, it is very difficult for employees to do the selection. The goal of this research is to determine the quality of shiitake mushrooms using deep learning and video image processing.

Extraction of As(III) from hydrochloric acid solution using various solvents on the basis of ion solvation has been reported, but a theoretical framework to describe the suitability of solvents for extraction has not been systematized. In this study, comprehensive extraction tests for As(III) using a variety of organic solvents were conducted to clarify the requirements for solvents to extract As(III). From the results of initial screening tests, various aromatics, ethers, and ketones were rated as candidates for the extraction of As(III) at high HCl concentrations, whereas aliphatic hydrocarbons were excluded. Many solvents showed high extraction capacity for As(III) to give organic fraction concentrations of 150 mM or higher. The logP value (P = partitioning coefficient between n-octanol and water) within a solvent class showed some correlation with extractability of As(III) but the correlation was invalid across solvent types. High correlation was shown between the Hansen solubility parameters of the solvents and As(III) extractability: Twenty of 22 solvents (90.9%) were appropriately classified as valid or invalid for the extraction of As(III) based on the Hansen sphere. 2-Nonanone was recommended as an ideal solvent for As(III) extraction because of its good balance between high extractability and its desirable physical properties for industrial operations. As(III) was quantitatively stripped from 2-nonanone into water with a concentration factor of 22.6.

If calixarenes can be dissolved in a relatively safe non-halogen solvent, they can be used in a liquid-liquid extraction process suitable for mass processing. In the present study, extraction behavior of metal ions using a calix[4]arene carboxylic acid derivative (<sup>t</sup>Oct[4]CH<sub>2</sub>COOH) dissolved in aromatic ethers was investigated. The solubility of <sup>t</sup>Oct[4]CH<sub>2</sub>COOH in aromatic ethers decreases with increase of the length of aliphatic side chain of the ethers. The solubility of <sup>t</sup>Oct[4]CH<sub>2</sub>COOH in 1-butoxybenzene (BB) was 28.0 mmol/L, which is smaller than that in chloroform but is higher than those in hexane and toluene. Divalent metal ions Mn(II), Co(II), Ni(II), Cu(II), Zn(II), and Pb(II) were extracted using <sup>t</sup>Oct[4]CH<sub>2</sub>COOH in BB through proton exchange reaction at similar pH range in toluene, which is higher than that in chloroform. The extraction reaction of Cu(II) using <sup>t</sup>Oct[4]CH<sub>2</sub>COOH in BB was determined by slope analysis and loading test. The stoichiometry between <sup>t</sup>Oct[4]CH<sub>2</sub>COOH and Cu(II) was 2:1.

Currently, there is a great demand for the development of nanomedicine aided wound tissue regeneration via silver doped nanoceuticals. Unfortunately, very little research is being carried out on antioxidants-doped silver nanometals and their interaction on the signaling axis during the bio-interface mechanism. In this study, c-phycocyanin primed silver nano hybrids (AgcPCNP) were prepared and analyzed for properties such as cytotoxicity, metal decay, nanoconjugate stability, size expansion, and antioxidant features. Fluctuations in the expression of marker genes during cell migration phenomena in in vitro wound healing scenarios were also validated. Studies revealed that physiologically relevant ionic solutions did not exhibit any adverse effects on the nanoconjugate stability. However, acidic, alkali, and ethanol solutions completely denatured the AgcPCNP conjugates. Signal transduction RT<sup>2</sup>PCR array demonstrated that genes associated with NFĸB- and PI3K-pathways were significantly (p < 0.5%) altered between AgcPCNP and AgNP groups. Specific inhibitors of NFĸB (Nfi) and PI3K (LY294002) pathways confirmed the involvement of NFĸB signaling axes. In vitro wound healing assay demonstrated that NFĸB pathway plays a prime role in the fibroblast cell migration. In conclusion, the present investigation revealed that surface functionalized AgcPCNP accelerated the fibroblast cell migration and can be further explored for wound healing biomedical applications.

<p>Adsorption behaviors of metal ions were studied on a crosslinked polyvinylamine resin, which was prepared by suspension polymerization of crosslinked polyvinylamide resin followed by hydrolysis. Precious metal ions present as anionic chloride complexes in hydrochloric acid were selectively adsorbed from among many base metals. As a synthetic resin, the adsorbent has a large number of functional groups (primary amino groups) per unit mass and can be obtained at relatively low cost. Maximum adsorption capacity of Hym-A for Pd(II) calculated by the Langmuir equation was 1.68 mmol g-1, which was 1.87 times that of a polyamine-based chelate resin. For comparison, the adsorption of the hazardous elements arsenic and selenium was also investigated. Hym-A adsorbed As(V) over a wider pH range than the chelating resin bearing secondary amines as functional groups. The maximum adsorption capacities of Hym-A for As(V), Se(IV) and Se(VI) were respectively 3.97, 2.42 and 2.31 times larger than those of a commercial resin. The adsorbent can thus be used for recovery of precious metals and removal of harmful elements with a larger throughput.</p>

Separation and Purification Technology 258 118008 2021.3
Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Separation and Purification Technology
© 2020 Elsevier B.V. Ethereal compounds, such as the commercially available extractant dibutyl carbitol (DBC), can extract Au(III) from acidic chloride media by ion solvation. Herein, various aromatic ether compounds comprising an aromatic ring and aliphatic chains were prepared to compare the extraction affinity toward Au(III) without dilution. Aromatic monoethers are not useful for the extraction of Au(III). Conversely, the extraction of Au(III) using aromatic 1,2-diethers increases as a function of hydrochloric acid concentration. For aromatic 1,2-diethers, the shorter the aliphatic chain, the higher the extraction affinity toward Au(III). 1,2-Dimethoxybenzene (o-DMB), which has the shortest side chains, exhibits the highest extraction affinity. 1,3-Dimethoxybenzene (m-DMB), which is a regioisomer for o-DMB, was not suitable for the extraction of Au(III). The extraction selectivity toward Au(III) over that of Fe(III) and Ga(III) using o-DMB, under high concentrations of hydrochloric acid, is higher than that using DBC. Selected aromatic 1,2-diethers, including o-DMB, show a significantly higher extraction capacity toward Au(III) than the industrial requirement of 30 g/dm3. Au(III) extracted using o-DMB was quantitatively recovered by reduction with oxalic acid. In a separation test from a mixed system comprising seven metals, Au(III) was selectively extracted and with a recovery percentage, after reduction, reaching 95.7%.

© 2019 Japan Association of Solvent Extraction. All rights reserved. To date, many kinds of chelating extractants have been developed, however, many of the good extractants are insoluble in aliphatic solvents. In the present study, cyclopentyl methyl ether (CPME) was assessed as a solvent for extractants to develop new solvent extraction systems. Many of the extractants (100 mM) were soluble in CPME. The extraction behavior of metal ions using a typical chelating extractant, 8-quinolinol (HQ) in CPME, was studied. The extraction profiles of metal ions using HQ in CPME were similar to those in toluene, whereas metal ions were extracted using HQ in 1-octanol and chloroform under lower pH conditions. The extraction reaction of In(III) using HQ in CPME was confirmed by slope analysis. A 3: 1 complex between HQ and In(III) was formed in CPME by a proton exchange reaction, and the extraction equilibrium constant was determined. In(III), extracted using HQ in CPME, was quantitatively recovered using mineral acids. From the results, CPME was found to be a potential alternative solvent to other toxic organic solvents for the development of a solvent extraction system.

Language：English Publishing type：Research paper (scientific journal) Publisher：Hydrometallurgy
© 2018 An aromatic ethereal compound, 1-methoxy-2-octoxybenzene, was recently found to be a good extractant for Au(III) from hydrochloric acid media. The present study therefore investigated the structural factors of ethereal compounds for the extraction of Au(III) under dilute extractant concentrations. In the series of aromatic ethereal compounds used in this study, 1-dodecoxybenzene showed the highest extractability for Au(III). There was a clear correlation between the extractability of Au(III) and the strength of hydrophobicity of the aromatic ethereal compounds. Au(III) was selectively extracted using 1-dodecoxybenzene over other precious- and base-metal cations. Au(III) was quantitatively stripped from this extractant using aqueous thiourea solution.

Recently, cyclopentyl methyl ether (CPME) has found use as a commercially available solvent for various applications. As CPME shows better properties such as more hydrophobicity, less solublity in water, less volatility, and more stablity compared with typical ethereal solvents, it could be used as a diluent or an extractant in liquid-liquid extraction systems. In the present study, CPME was found to be useful for the extraction of Au(III) in hydrochloric acid media. Extraction of Au(III) increased with as increase in the hydrochloric acid concentration. Au(III) was selectively extracted using CPME from other precious metal ions and base metal ions. From the result of the dependency of the Au(III) concentration, CPME can load at least 0.93 g/dm<sup>3</sup> Au(III). Extracted Au(III) was quantitatively stripped from CPME using 0.1 M aqueous thiourea solution. As the solubility of water into CPME is much smaller than that into alcohols such as 1-hexanol, CPME is more favorable as an extractant for Au(III) in hydrochloric acid media.
