'Muslim Diaspora' in Yuan China: A Comparative Analysis of Islamic Tombstones from the Southeast Coast

MUKAI, Masaki The Asian Association of World Historians 2016 The Asian review of world histories Vol.4 No.2

This paper presents a case study of the Muslim diaspora through comparative analysis of Islamic tombstones from the Southeast Coast of China under Mongol rule. The locations of the nisbas in the Islamic tombstones are widely dispersed, covering Xinjiang, Transoxiana, Iran, Khorasan, Khwarazm, Armenia, Syria, Palestine, and Arabia. Unexpectedly, we did not find a single named location from India or Southeast Asia. It is well known that notable descendants of distinguished families traditionally produced officials, intellectuals, and wealthy merchants, and surrendered to the Mongols during the war against the Qara Khitai Khanate and the Khwarazm Empire. There were a great number of appointed officials with Muslim names in the Jianghuai (around Lower Yangtze) and Fujian regions. This is consistent with the concentration of epitaphs written in Arabic on the southeast coast of China. The frequent use of the specific tradition of the prophet Muhammad associating the death of the exile with martyrdom in Islamic tombstones in Quanzhou, Hangzhou, and Yangzhou indicates that the Muslims in these port cities eventually established an interregional or diasporic identity of Muslim foreighners whoimmigrated into the region.

Mukai Jun (사)한국디지털디자인협의회 2007 (사)한국디지털디자인협의회 conference Vol.2007 No.1

Lately design is trending toward simplification, that is, simple design is good design. As proving such design trend, a representative internal graphic designer, Shigeo Fukuda's work is deemed a successful case of simple design. Japanese graphic design was widely known throughout the world by designer Shigeo Fukuda. Inclination of his works has strong boundary and definiteness in application of image or color, along with easy delivery of message through forming object line in the center, drawing interest by connecting an object with various meaning to another object.

Karyotype Analysis of Parthenote ⇔ Tetraploid Chimeric Blastocysts in Mice

MUKAI, M.,TAKAHASHI, J.,YASUDA, Y.,강민수 濟州大學校 農科大學 動物科學硏究所 1997 動物科學論叢 Vol.12 No.1

Parthenote ⇔ tetraploid chuneric embryos were produced by aggregation of a parthenogenetically activated embryo and a tetraploid embryo. The karyotype of these chimeric embryos were observed 48h after aggregation of embryos. Tetraploid embryos were produced by electrofusion at the 2-cell stage, and about 64% of these embryos developed to blastccysts. Parthenogenetic embryos were obtained by ethanol treatment. Eggs with second polar bodies were selected as haploid parthenogenetically activated embryos. The rate of activation was 71%, and 63% of these activated ova developed to 8-cell stage embryos. Thuty-six percent of haploid parthenote ⇔ tetraploid chimeric embryos developed to blastcysts. Chromosomal analysis of chmeric embryos showed that these embryos were consisted of haploid (n) ⇔ diploid (2n), diploid (2n) ⇔ tetraploid (4n), only haploid(n), only dploid(2n) and only tetraploid chromosome constitution. These results suggested the following three points. Firstly, parthenote ⇔ tetraploid chimeric embryos can develop to blastocysts, secondly, parthenogenetic or tetraploid cell may diploidize spontaneously, and thudly, diploid cell ratio increased with the numbers of cells per blastocyst.

Study on Generation of Harmonic Voltage using Synchronous Machine with d-axis and q-axis Harmonic Field Windings

Mukai, Eiichi,Kakinoki, Toshio,Yamaguchi, Hitoshi,Kimura, Yoshimasa,Fukai, Sumio Journal of International Conference on Electrical 2013 Journal of international Conference on Electrical Vol.2 No.3

We examined the generation of harmonic voltage by a synchronous machine adding d-axis and q-axis harmonic field windings in order to reduce the harmonics in a power line. We derived the expressions of the armature voltage in the case of supplying the currents with the frequency nf to the d-axis and q-axis harmonic field windings. We constructed the synchronous machine adding the harmonic windings. In this paper, the expressions and the experimental results on the generation of harmonic voltages by the synchronous machine are presented.

Study on Generation of Harmonic Voltage using Synchronous Machine with d- and q-axis Harmonic Field Windings - Part 2

Mukai, Eiichi,Fukai, Sumio,Kakinoki, Toshio,Yamaguchi, Hitoshi,Kimura, Yoshimasa Journal of International Conference on Electrical 2014 Journal of international Conference on Electrical Vol.3 No.2

We investigated the harmonic voltages generated by a synchronous machine adding d-axis and q-axis harmonic field windings to reduce the harmonics in a power line. First, electronic circuits such as a frequency multiplier, band-pass filter, and phase shifter were newly designed and made to carry out the experiment. Next, an experimental circuit, for which an AC voltage of frequency 6f synchronized to the power line voltage of frequency f could be obtained, was constructed to examine the generation of harmonic voltage in more detail. Finally, an experiment involving the generation of harmonic voltage was performed using an experimental synchronous generator with harmonic windings in the d-axis and q-axis. In this paper, the power spectrum and the waveforms of the harmonic voltages in the armature winding are presented. Moreover, the values calculated from theoretical expressions of harmonic voltages in armature winding are compared with the values obtained by the experiment.

Development of a conformal woven fabric antenna for wearable breast hyperthermia

Yusuke Mukai,Minyoung Suh 한국의류학회 2021 Fashion and Textiles Vol.8 No.1

Breast hyperthermia is a non-invasive cancer treatment, where breast temperature is mildly elevated by a localized electromagnetic (EM) irradiation to deactivate and damage cancer cells. The emerging needs associated with this medical modality include the development of a highly wearable microwave applicator with a low power requirement to enable a more patient-friendly and continuous hyperthermia therapy. As a potential solution, we propose a textile antenna that consists of a copper-plated woven polyester fabric as a radiating patch and a ground plane and a woven polyester fabric as a dielectric substrate and a padding layer. The porous nature of these textile materials enables construction of a lightweight and flexible antenna with a low dielectric loss for a more comfortable hyperthermia treatment. By incorporating a synthetic breast tissue for a model study, the temperature rises were measured to be 3.3 °C and 1.9 °C at 5 mm and 15 mm depths, respectively, after 15 min of heating (input power of 1 W). This suggests that the textile-based approach could be an effective solution for comfortable and long-term applications of breast hyperthermia therapy.

Prospect of plant molecular cytogenetics in the 21st century

Yasuhiko Mukai 한국생명과학회 2003 한국생명과학회 심포지움 Vol.40 No.-

The genomes of Arabidopsis and rice have been fully sequenced. Genomic sequencing provides global information about genome structure and organization. A comprehensive research account of our recent studies conducted on genome painting, comparative genomics and genome fusion is provided in order to project the prospects of plant cytogenetic research in post-genomics era. Genome analysis by GISH using genome painting is demonstrated as an excellent means suitable for visualization of a whole genome, since total genomic DNA representing the overall molecular composition of the genome is used as a probe. FISH on extended DNA fibers has been developed for high-resolution FISH and has contributed to determining the copy number and order of genes. We have also mapped a number of genes involving starch synthesis on wheat chromosomes by FISH and compared the position of these genes on linkage map of rice. Macro synteny between wheat and rice can be observed by comparing the location of these genes in spite of the fact that the size of DNA per chromosome differs by 20 fold in two. Moreover, to approach our goal towards making bread and udon noodles from rice flour in future by incorporating bread making and the noodle qualities in rice, we have been successful in introducing large genomic DNA fragments containing agronomically important genes of wheat into a rice by successive introduction of large insert BAC clones, there by expanding genetic variability in rice. We call this method genome fusion.
