S. Ishida,P. Barabaschi,Y. Kamada 한국물리학회 2014 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.65 No.8
The JT-60SA project has been implemented jointly by Europe and Japan since June 2007. Afterthe disassembly of JT-60 from the torus hall had been completed in October 2012, the projectachieved the major milestone of starting the tokamak’s assembly at the JAEA Naka site in January2013 following the completion of the cryostat base in Europe and its transport to Japan. Procurementand assembly activities for components such as the superconducting magnet, cryogenicsystem, power supply, vacuum vessel, divertor and cryostat are progressing on track towards thestart of operation in March 2019. In preparation for exploitation, the JT-60SA Research Plan wasissued in December 2011, and the research integration activities are addressing JT-60SA data management,validation and analysis tools. This paper overviews the latest evolution of the project interms of construction and exploitation for JT-60SA.

Iwakiri, S.,Song, J.Y.,Nakayama, K.,Oh, M.J.,Ishida, M.,Kitamura, S.I. Academic Press 2014 FISH AND SHELLFISH IMMUNOLOGY Vol.38 No.2
Lymphocystis disease virus (LCDV) is the causative agent of lymphocystis disease (LCD). In this study, we investigated the mechanisms of lymphocystis cell (LCC) formation from the viewpoint of gene expression changes in the infected fish. LCC occurrence and virus titers in the experimentally infected Japanese flounder, Paralichthys olivaceus were monitored by visual confirmation and real-time PCR, respectively. The gene expression changes in the fish fin were investigated by microarray experiments. LCCs firstly appeared in the fish at 21 days post infection (dpi). LCD incidence increased with time and reached 92.9% at 62 dpi. LCDV genome was firstly detected from dorsal fins at 14 dpi, and the relative amount of the genome gradually-increased until 56 dpi. Since the occurrence of LCC was approximately synchronized with increasing of the virus genome, virus replication might play important roles for LCC formation. The microarray detected a few gene expression changes until 28 dpi. However, the number of expression changed genes dramatically increased between 28 and 42 dpi in which LCCs formation was active. From the microarray data analyses, apoptosis and cell division related genes were down-regulated, whereas cell fusion and collagen related genes were up-regulated at 42 dpi. Together with the observation of morphological changes of LCCs in previous reports, it is suggested that the following steps are involved in LCC formation: the virus infected cells were (1) inhibited apoptotic death and (2) cell division before enlargement, (3) hypertrophied by cell fusion, and (4) surrounded by a hyaline capsule associated with the alteration of collagen fibers.

Hot wall epitaxy법에 의하여 GaAs(100)면 위에 ZnS-ZnSe 초격자를 성장하였다. ZnS-ZnSe 초격자의 주기는 x-선 회절 패턴에 의하여 확인되었고, 이것은 변형을 고려하여 계산된 이론적인 패턴과 비교되었다. 경계면에 평행한 ZnS와 ZnSe의 변형의 비는 ZnSe에 대하여 ZnS의 두께가 증가할수록 감소되었다. ZnS-ZnSe 초격자의 photoluminescence(PL)는 고에너지 영역의 예리한 스펙트럼과 저에너지 영역의 폭이 넓은 스펙트럼으로 구성되어 있다. PL의 광자 에너지는 Kronig-Penney 모델을 사용하여 계산된 이론적인 에너지 값과 비교한 결과 type I의 초격자임을 알았다. ZnS-ZnSe superlattices(SLs) were grown on the GaAs(100) by hot wall epitaxy. The period of ZnS-ZnSe SLs grown was confirmed by X-ray diffraction patterns, and compared with the theoretical pattern calculated considering the strain. It was calculated that the strain ratios of ZnS and ZnSe parallel to interfaces are decreased with increasing the ZnS thickness for ZnSe one. The photoluminescence(PL) of ZnS-ZnSe SLs consists of a sharp. line in the high energy region and of broad spectra in the lower energy region. The peak photon energy of ZnS-ZnSe PL was compared with the energy of the theoretical calculations using Kronig-Penney model, and ZnS-ZnSe SLs were considered to be type I.

We have identified and cloned an odorant-binding protein from the female mosquito, Culex tarsalis (CtarOBP). As expected for an olfactory protein, CtarOBP was detected by gel electrophoresis analysis in antennae but not in control tissues (legs). The isolated protein was identified by in-gel digestion and subsequent analysis of internal fragments by tandem mass spectrometry (MS-MS). Based on the amino acid sequences of two peptides generated by enzymatic digestion, degenerate primers were designed for cDNA cloning. The complete cDNA (cloned by RACE) encoded a protein with a signal peptide (24 residues) and a mature protein of 125 amino acid residues. The calculated molecular mass and isoelectric point of the mature protein were 14,515 Da and pI 5.5, respectively. CtarOBP showed the hallmark of odorant-binding proteins, 6 cysteine residues, and high sequence homology (61-96%) to previously characterized mosquito OBPs.
ENHANCEMENT OF NOx-PM TRADE-OFF IN A DIESEL ENGINE ADOPTING BIO-ETHANOL AND EGR
S. JUNG,M. ISHIDA,H. UEKI,D. SAKAGUCHI 한국자동차공학회 2010 International journal of automotive technology Vol.11 No.5
−For realizing a premixed charge compression ignition (PCCI) engine, the effects of bio-ethanol blend oil and exhaust gas recirculation (EGR) on PM-NOx trade-off have been investigated in a single cylinder direct injection diesel engine with the compression ratio of 17.8. In the present experiment, the ethanol blend ratio and the EGR ratio were varied focusing on ignition delay, premixed combustion, diffusive combustion, smoke, NOx and the thermal efficiency. Very low levels of 1.5 [g/kWh] NOx and 0.02 [g/kWh] PM, which is close to the 2009 emission standards imposed on heavy duty diesel engines in Japan, were achieved without deterioration of the thermal efficiency in the PCCI engine operated with the 50% ethanol blend fuel and the EGR ratio of 0.2. It is found that this improvement can be achieved by formation of the premixed charge condition resulting from a longer ignition delay. A marked increase in ignition delay is due to blending ethanol with low cetane number and large latent heat, and due to lowering in-cylinder gas temperature on compression stroke based on the EGR. It is noticed that smoke can be reduced even by increasing the EGR ratio under a highly premixed condition.
Fodder Supply in Cold Season in Gobi Nomadic Area, Mongolia
Yamasaki, S.,Ishida, J. Asian Australasian Association of Animal Productio 2004 Animal Bioscience Vol.17 No.2
Fodder supply condition was studied at 41 nomadic families in Gobi, Southern Semi-Desert area in Mongolia, from Dec. 1994 to Apr. 1995 to determine problems in cold, feed deficient season for establishment of sustainable livestock production system. The conditions of two family groups: those located in sparse vegetation (FG1), and those in comparably dense (FG2), were also compared. Commercial concentrate feed (concentrate), hay and Zoodoi were prepared for supplementation. Zoodoi was hand-made feed made mainly of Allium mongolicum and Allium polyrrhizum. Allium mongolicum tended to be used at FG1 frequently, and Allium polyrrhizum at FG2 depend on differences of micro vegetation. 44%, 90% and 39% of families prepared 165.6 kg of concentrate, 301.6 kg of hay and 6.8 kg of Zoodoi per sheep and goat (small livestock) on the average, respectively. The ratio of families that used concentrate at FG1 was smaller than those at FG2, though there were no significant differences on the amount. More hay was fed at FG1 than at FG2, and Zoodoi tended to be fed more in the FG1 group. Recipients were mostly restricted to young, female and sick small livestock that use the feeds effectively. More families gave concentrate and hay to the young than to the females and sick. They also gave more Zoodoi to young and sick animals than to females in this area. In the FG1 group, no differences were found between recipients on the concentrate supply. More families supplied hay to young animals than to sick ones, and Zoodoi was fed more to sick animals than to young and females. On the other hand, those in the FG2 found, more families fed fodders to young than to female and sick regardless of the kinds of feeds. The amount of fodder supplementation in the studied area was restricted, but accurate techniques of nomads to adapt the situation were clarified.
