       Bioassays using cells and bacteria have recently attracted great attention as new environmental toxicity tests or alternatives to animal experiments, since they can evaluate comprehensive influences to ecosystems or human in terms of toxicity. However, the target of almost all tests is water samples. We here described development and evaluation new toxicity test systems for gaseous samples from industry and its waste, exhaust gases from cars, and various gases in the environment.

       In order to study the electronic states of proteins, we have developed the all-electron canonical wavefunction program of protein, ProteinDF, and updated the largest calculation record. It is important for the achievement of large-scale calculations to prepare the various processing such as the structural decision, the simulation control, and the analysis of the calculation result, etc. We have developed the integrated environment, ProteinEditor which unifies those processing and supplies an interactive controls to the users. In this report, we introduce the standard functions of ProteinEditor and a newly developed protein modeling function by VR technology.

       It was found that coal-gasification-slag, which can foam to be reduced its density by high-temperature heating, discharged from integrated coal gasification combined cycle system power generation can be effectively applied to lightweight fine aggregate for concrete. From comparative tests on fresh, strength and durability properties among concretes with heat-foamed coal-gasification-slag, commercially produced lightweight fine aggregate and ordinary natural sand, respectively, it was clarified that concrete with heat-foamed coal-gasification-slag gave the same or more performance than with commercially produced lightweight fine aggregate.

       Hydraulic model experiment is carried out to reproduce thermally-induced circulations in a model lake like Lake Biwa, including the effect of earth's rotation. In order to take the topographic heat accumulation effect into account, peltier devices are arranged along the coast of the distorted model for heating and cooling of coastal waters. As a result, the experiment reproduces the counterclockwise and clockwise gyres during heated and cooled durations, respectively. However, during cooled duration, the velocity of water current is smaller than that of observation and numerical simulation due to weak vertical mixing. Hence this experiment shows that complete vertical mixing of waters in winter may be ceased as atmospheric temperature rises due to global warming.[This abstract is not included in the PDF]
