目前在日本,存在大量工业垃圾,包括各种塑料制品,ASR(汽车破碎垃圾),含有毒PCB(多氯联苯)的110变压器和PVC(聚氯乙稀)制品等.而来自城市垃圾焚烧炉的废气含有大量能量.因此,在充分考虑环境、避免二垩英生成的同时,安全回收来自工业垃圾、城市和/或工业垃圾焚烧炉的资源和能量是个非常重要的课题,这也将对抑制CO2排放作出贡献.正确地阐明焚烧过程中二垩英的生成机理及详细研究含少量二垩英的焚烧废气在冷却过程中大量形成二垩英的临界温度是项很重要的工作.解决这个问题可有效实现资源和能量的回收.本报告介绍日本在二垩英排放方面目前采取的对策和存在的问题以及大阪大学为阻止二垩英生成所做的基础研究工作. 相似文献

The use of an agent in the environment, as in medical treatment, welfare, the construction field, and the home, is examined.
It is necessary for the agent to be able to work cooperatively with a human, and that may be a problem. Therefore, this study
pays attention to the phenomenon that is called entrainment. This is the phenomenon where the rhythm of a certain person and
the partner in the communication is synchronized. The purpose of this study is to perform a basic examination into applying
an entrainment in order to realize cooperation in operations between a human and an agent. Since many human rhythms are expressed
by a nonlinear oscillator, we simulated limited cycle oscillators, which are one of two nonlinear oscillators that cause interactions
between agents, as the basic examination for this achievement. Consequently, entrainment of limited cycle oscillators with
rhythms which differ has been checked in certain conditions. As a result, the possibility that cooperative movement could
be gained was suggested. 相似文献

Our purpose is to develop the technology for evaluating emotion objectively from the oxygenated hemoglobin within a brain. Nowadays, Japan is an aging society. The elderly people who need care will increase from now on increasingly. In the case of the person requiring the care who lost the function to convey an intention especially, the objective judgment to a physical and mental pain is required. Persons requiring care will also increase in number with the increase in this population. We gave subject stimulus of a comfortable or an uncomfortable sound and measured concentration of the oxygenated hemoglobin of a frontal lobe part by near-infrared spectroscopy. Based on the experimental result, a comfortable state or an uncomfortable state was distinguished by concentration of the oxygenated hemoglobin using the bayesian network. As a result, we were able to estimate the subject’s psychological condition. 相似文献

Recently, there has been much interest in the study of the formation of groups of agents that cause interactions between agents and invent new functions. We gave some agents an action rule based on the interactions of human feelings by using a circumplex model. It had been decided that the parameters of feelings in this model should have only two axes. In this report, eight basic action dimensions and pure feelings on four corresponding axes were given to agents as a model of feelings and actions based on the multiple factor analysis theory of R. Plutchik, and the behavioral characteristics of the group of agents were examined. 相似文献

This paper proposes a loss minimum reconfiguration method by tabu search for an open‐loop radial distribution system with distributed generators. The problem is to find the optimal normal open sectionalizing switch positions which minimize the total distribution line losses subjected to the line/transformer capacity constraints and voltage constraint. Generally, the problem is mathematically formulated as a complex combinatorial optimization problem or mixed integer programming problem, and is solved by using mathematical programming method, heuristic algorithm, intelligent method, and so on. However, a satisfactory algorithm for power companies has not yet been attained in both computational burden and solution accuracy. Thus, in this paper, the authors propose a method to solve the above problem by using tabu search (TS). Reverse power flow caused by distributed generators can be included in the solution algorithm. TS is one of the meta‐heuristic algorithms, and sometimes has been evaluated to be better than genetic algorithm (GA) or simulated annealing (SA) from viewpoints of both computational speed and solution accuracy. In order to evaluate the validity and efficiency of the algorithm, several numerical examples are shown in this paper. © 2005 Wiley Periodicals, Inc.

Apparatus comprising a scanning tunneling microscopy (STM) and an atomic force microscopy (AFM) has been developed for use under supra-atmospheres. Observations of highly oriented pyrolytic graphite (HOPG) were carried out by STM and contact AFM operating in air and various gas atmospheres (hydrogen, helium, neon and argon) under pressures up to 1.1 MPa. Atomic resolution images of the HOPG were obtained by STM in all the gas atmospheres studied. However, it was found that the presence of water vapor gave rise to a noise current at increased pressures. Using contact AFM, the atomic resolution in an argon atmosphere decreased with increasing pressure, while atomic images were obtained under the other gas atmospheres at 1.1 MPa. 相似文献

Fatty acid esters of hydroxy fatty acids (FAHFAs) are a new class of endogenous lipids with interesting physiological functions in mammals. Despite their structural diversity and links with nuclear factor erythroid 2-related factor 2 (NRF2) biosynthesis, FAHFAs are less explored as NRF2 activators. Herein, we examined for the first time the synthetic docosahexaenoic acid esters of 12-hydroxy stearic acid (12-DHAHSA) or oleic acid (12-DHAHOA) against NRF2 activation in cultured human hepatoma-derived cells (C3A). The effect of DHA-derived FAHFAs on lipid metabolism was explored by the nontargeted lipidomic analysis using liquid chromatography-mass spectrometry. Furthermore, their action on lipid droplet (LD) oxidation was investigated by the fluorescence imaging technique. The DHA-derived FAHFAs showed less cytotoxicity compared to their native fatty acids and activated the NRF2 in a dose-dependent pattern. Treatment of 12-DHAHOA with C3A cells upregulated the cellular triacylglycerol levels by 17-fold compared to the untreated group. Fluorescence imaging analysis also revealed the suppression of the degree of LDs oxidation upon treatment with 12-DHAHSA. Overall, these results suggest that DHA-derived FAHFAs as novel and potent activators of NRF2 with plausible antioxidant function. 相似文献
