High Purity Ferric Oxide : Origin of Impurities and IROX-NKK Purification Process
Maeda, T. The Korean Institute of Resources Recycling 2002 資源 리싸이클링 Vol.11 No.5
A new process based on the co-precipitation method was developed fer removing harmful impurities during Mn-Zn ferrite production such as $SiO_2$ and P from waste pickle liquor. By this process a final result of less than 100 ppm of $SiO_2$ and less than 10 ppm of P content in the ferric oxide is easily attained. Though Ca cannot be removed by this process, water rinsing of the ferric oxide is effective fer reducing Ca content to less than 100 pm. For further purification, the origins of each impurity must be investigated and then taken away.
PROTEIN POLYMORPHISMS IN NATIVE AND RED JUNGLE FOWLS IN NEPAL
Maeda, Y.,Yamamoto, Y.,Nishida, T.,Hashiguchi, T.,Okada, I.,Rajubhandary, H.B. Asian Australasian Association of Animal Productio 1992 Animal Bioscience Vol.5 No.4
Protein polymorphism of native and red jungle fowls in Nepal was analyzed by electrophoresis. Blood samples were collected in the areas of Solu, Jomson road, Kathmandou, Pokhara and Low land. Out of 17 loci, polymorphism were found at nine loci in native fowls and at three loci in red jungle fowls. The proportion of polymorphic loci ($P_{poly}$) of native and red jungle fowls were $0.529{\pm}0.121$ and $0.176{\pm}0.095$, respectively. The five fowl populations in Nepal formed a different cluster from Sri Lankan and Bangladeshi fowl populations. When the gene frequencies of polymorphic loci were compared between the native fowl populations of Sri Lanka, Bangladesh and Nepal, $Amy-1^A$, $Es-1^A$ and $Akp-2^A$ genes showed inclination of south to north.
BLOOD PROTEIN POLYMORPHISMS OF NATIVE AND JUNGLE FOWLS IN INDONESIA
Hashiguchi, T.,Nishida, T.,Hayashi, Y.,Maeda, Y.,Mansjoer, S.S. Asian Australasian Association of Animal Productio 1993 Animal Bioscience Vol.6 No.1
In an attempt to reveal the interrelationship between fowls of jungle and native origin, their gene constitutions were compared using gene frequencies at the 16 loci controlling blood protein variations. Of the 16 loci analysed by electrophoresis, polymorphism was detected at following seven loci: Es-1, Amy-1, Akp-akp, Akp-2, Alb, Tf and 6-PGD. The other nine loci: Amy-3, Es-D, PGM, PHI, MDH, To, LDH, Hb-1 and Hb-2, were noted to be monomorphic. Genetic distance between pairs of native fowl and jungle fowls was estimated by a numerical taxonomic method. The Indonesian native fowl was genetically close to the Indonesian red jungle fowl, and the grey jungle fowl was genetically similar to the Ceylonese jungle fowl. It was also suggested that the green jungle fowl was genetically remote from the other jungle fowls and from the Indonesian native flow. The proportion of polymorphic loci (Ppoly), the expected average heterozygosity per individual $\bar{H}$, and the effective number of alleles per locus (Ne) were calculated to evaluate the genetic variabilities in the native and jungle fowls. The Indonesian native fowl exhibited slightly higher the proportion of polymorphic loci than the jungle fowls.

The present article briefly overviews the plan for a new project on joint technology for HTS wires/cables and describes the development plan for the world's highest field NMR magnet, which is a major development item in the project. For full-fledged social implementation of superconducting devices, high temperature superconducting (HTS) wire is a key technology since they can be cooled by liquid nitrogen and they can generate a super-high magnetic field of >>24 T at liquid helium temperatures. However, one of the major drawbacks of the HTS wires is their availability only in short lengths of a single piece of wire. This necessitates a number of joints being installed in superconducting devices, resulting in a difficult manufacturing process and a large joint resistance. In Japan, a large-scale project has commenced, including two technical demonstration items: (i) Development of superconducting joints between HTS wires, which are used in the world's highest field 1.3 GHz (30.5 T) NMR magnet in persistent current mode; the joints performance is evaluated based on NMR spectra for proteins. (ii) Development of ultra-low resistive joints between DC superconducting feeder cables for railway systems. The project starts a new initiative of next generation super-high field NMR development as well as that of realization of better superconducting power cables.
CONSTRAINING SUPERNOVA PROGENITORS: AN INTEGRAL FIELD SPECTROSCOPIC SURVEY OF THE EXPLOSION SITES
KUNCARAYAKTI, H.,ALDERING, G.,ANDERSON, J.P.,ARIMOTO, N.,DOI, M.,GALBANY, L.,HAMUY, M.,HASHIBA, Y.,KRUEHLER, T.,MAEDA, K.,MOROKUMA, T.,USUDA, T. The Korean Astronomical Society 2015 天文學論叢 Vol.30 No.2
We describe a survey of nearby core-collapse supernova (SN) explosion sites using integral field spectroscopy (IFS) techniques, which is an extension of the work described in Kuncarayakti et al. (2013). The project aims to constrain SN progenitor properties based on the study of the immediate environment of the SN. The stellar populations present at the SN explosion sites are studied by means of integral field spectroscopy, which enables the acquisition of both spatial and spectral information of the object simultaneously. The spectrum of the SN parent stellar population gives an estimate of its age and metallicity. With this information, the initial mass and metallicity of the once coeval SN progenitor star are derived. While the survey is mostly done in optical, the additional utilization of near-infrared integral field spectroscopy assisted with adaptive optics (AO) enables us to examine the explosion sites in high spatial detail, down to a few parsecs. This work is being carried out using multiple 2-8 m class telescopes equipped with integral field spectrographs in Chile and Hawaii.
Development of Computer Simulation Code of Excimer Lasers and Experimental Confirmation
M.Maeda,T.Okada,K.Muraoka,K.Uchino 한국조명·전기설비학회 1999 한국조명·전기설비학회 학술대회논문집 Vol.1999 No.-
In order to analyze the discharge-pumped KrF excimer laser, computer simulation code is developed. On the other hand, the electron velocity distribution in a discharge plasma, measured by the Thomson scattering method, showed the Maxwellian, while the code predicted non-Maxwellian. This disagreement was solved by introducing the electron-electron collision into the simulation code. We also developed a simulation code on the CO₂ laser-heated plasma in high-pressure Ar gas, ana estimated the formation process of Ar₂ excimer. The code predicted the possibility of the Ar₂ laser action at 126 nm.
