A NEW TREATMENT SYSTEM FOR ANIMAL WASTE WATER USING MICROORGANISM, SOIL AND VEGETATION
Oshida, T.,Fukuyasu, T.,Kohzaki, K.,Izumikawa, Y.,Kawanabe, S.,Konishi, S.,Oikawa, N.,Matsumoto, S. Asian Australasian Association of Animal Productio 1993 Animal Bioscience Vol.6 No.2
A new treatment system for animal waste water has been developed as an alternative to the activated sludge process. It consists of two treatments; one is operated with 7 tanks, and the other is soil and plant cultivation bed. Aerobic microorganisms are added to the influent water in the tanks where the water is aerated so that the microbes utilize the pollutants, while sedimentation removes the indigestible solids. In the secondary treatment the water, which has already received a primary treatment, is filtered through soil where it also receives treatment by soil organisms. In addition there is transpiration of water and absorption of minerals by plants. In the primary treatment BOD, SS, coliforms (E. coli), TP and total bacteria were removed 79-99%, but COD and TN were removed only 58% and 36%, respectively. In the secondary treatment removal of nutrients proceeded further, and 93-99% of pollutants were removed. The treated waters met the quality standard of discharge water in Japan except for TN, which was in too great a concentration to meet discharge standards. This problem requires further study.

This paper presents a novel prototype of the utility-interactive voltage source type sinewave pulse modulated power inverter using a high-frequency flyback transformer link The proposed power conditioner circuit for the solar photovoltaic generation and small scale fuel cell has an isolation function due to the safety of the power processing system, which is more cost effective and acceptable for the small-scale distributed renewal energy conditioning and processing systems. The discontinuous current mode(DCM) of this power processing conversion circuit is applied to implement a simple circuit topology and pulse modulated control scheme. Its operation principle is described on the basis of simulation evaluations and theoretical considerations. The simulation results obtained herein prove that the proposed inverter outputs with sinusoidal waveforms and unity power factor currents are synchronized to the main voltage in utility power source grid. In this paper, the soft switching topology of high-frequency linked sinewave pulse modulation inverter is proposed and discussed.<br/> Index Terms -High frequency link, Flyback transformer link, Sinewave modulated inverter, Utility interactive power processing, Solar photovoltaic power conditioner, Renewal conversion energy and sustainable energy, Soft-switching topology.<br/>
FUSION MATERIALS AND FUSION ENGINEERING R&D IN JAPAN
KOHYAMA A.,KONISHI S.,KIMURA A. Korean Nuclear Society 2005 Nuclear Engineering and Technology Vol.37 No.5
Japanese activities on fusion structural materials R&D have been well organized under the coordination of university programs and JAERI/NIMS programs more than two decades. Where, two categories of structural materials have been studied, those are; reduced activation martensitic/ferritic steels (RAFs) as reference material and vanadium alloys and SiC/SiC composite materials as advanced materials. The R&D histories of these candidate materials and the present status in Japan are reviewed with the emphasis on materials behavior under radiation damage. The importance of IFMIF and technology development for blanket R&D including ITER-TBRG activity is emphasized and the current status of those activities in Japan is also presented.

Snail1 is stabilized by O-GlcNAc modification in hyperglycaemic condition

Protein O-phosphorylation often occurs reciprocally with O-GlcNAc modification and represents a regulatory principle for proteins. O-phosphorylation of serine by glycogen synthase kinase-3β on Snail1, a transcriptional repressor of E-cadherin and a key regulator of the epithelial-mesenchymal transition (EMT) programme, results in its proteasomal degradation. We show that by suppressing O-phosphorylation-mediated degradation, O-GlcNAc at serine112 stabilizes Snail1 and thus increases its repressor function, which in turn attenuates E-cadherin mRNA expression. Hyperglycaemic condition enhances O-GlcNAc modification and initiates EMT by transcriptional suppression of E-cadherin through Snail1. Thus, dynamic reciprocal O-phosphorylation and O-GlcNAc modification of Snail1 constitute a molecular link between cellular glucose metabolism and the control of EMT.
