A Report on Research at the Center for English as a Lingua Franca 2020

2020 presented teacher/researchers in the field its own set of unique challenges. Conferences were cancelled, data collection was complex, and the shift to emergency remote teaching left very little time to focus on research activities. Despite these circumstances, faculty at The Center for English as a Lingua Franca (CELF) managed to maintain its strong connections to the academic community in the shape of participation in online conferences, publishing research articles, and helping different academic societies to adapt to the ‘new normal’. In this short report, we table the Center’s broad list of academic achievements.departmental bulletin pape

管弦楽組曲 第３番 ニ長調 BWV1068「アリア」（J.S.バッハ）

P(論文)「アリア」は，J.S.バッハが作曲した４曲の管弦楽組曲のうち，第３番の第２楽章である。編曲に用いた楽器の構成は，コンサート・フルート３部，アルト・フルートとバス・フルートが各１部である。アルトとバスについては，３部のコンサート・フルートの響きを支える低音として扱い，ユニゾンとした。コンサート・フルートの演奏者の人数によっては低音部の音量を補強する必要があることから，チェロを追加している。なお，コントラバス・フルートが演奏に加わる場合は，バスの楽譜を使用して１オクターヴ下で演奏する。本曲は，2017年6月25日に，岡山シンフォニーホール「スタジオ１」で開催された，「フルートオーケストラ“セレーナ”コンサートVol.12」において，編曲者自身の指揮によって演奏された。departmental bulletin pape

Modulation of host HIF-1α activity and the tryptophan pathway contributes to the anti-Toxoplasma gondii potential of nanoparticles

application/pdfBackground Toxoplasmosis constitutes a large global burden that is further exacerbated by the shortcomings of available therapeutic options, thus underscoring the urgent need for better anti-Toxoplasma gondii therapy or strategies. Recently, we showed that the anti-parasitic action of inorganic nanoparticles (NPs) could, in part, be due to changes in redox status as well as in the parasite mitochondrial membrane potential. Methods In the present study, we explored the in vitro mode of action of the anti-T. gondii effect of NPs by evaluating the contributions of host cellular processes, including the tryptophan pathway and hypoxia-inducing factor activity. NPs, at concentrations ranging from 0.01 to 200 μg/ml were screened for anti-parasitic activity. Sulfadiazine and/or pyrimethamine served as positive controls. Results We found that interplay among multiple host cellular processes, including HIF-1α activity, indoleamine 2,3-dioxygenase activity, and to a larger extent the tryptophan pathway, contribute to the anti-parasitic action of NPs. Conclusion To our knowledge, this is the first study to demonstrate an effect of NPs on the tryptophan and/or kynurenine pathway. General significance Our findings deepen our understanding of the mechanism of action of NPs and suggest that modulation of the host nutrient pool may represent a viable approach to the development of new and effective anti-parasitic agents.journal articl

Precipitation And Its Impacts For Global Scale Rice Production

Rice plays a major role in the global supply and demand for sustainable food production. Rice production has consistently outpaced population growth. Thus, rice plays a crucial role in supporting continued global population growth. The progress of technology, irrigation and rice varieties made it possible for farmers to produce more rice with tolerance for climate change. In 1992, because of abnormal climatic conditions, the yield of rice in Japan fell to less than 90% that of annual average production, where the technology for agriculture is thought to be well developed. At that time, Japan had to import rice. Thus the impact of climate change cannot be ignored. When discussing yield of rice, the impact of climatic conditions should be discussed. In this study, we focused on the relationships between yield of rice and precipitation datasets. Monthly precipitation datasets are provided from Global Precipitation Climatology Centre in Germany (hereafter we called “GPCC”). The resolution of GPCC is 0.5 degree and from west to east, numbers of columns are 720 and from north to south, numbers of rows are 360 and covers from January 1900 to December 2007. Datasets from January 1981 to December 2003 are used to calculate the country based relationships in this study. The Cropping Calendar dataset includes spatial information and provides five patterns such as Planting, Vegetative, Heading, Filling and Harvesting. The resolution of the cropping calendar is almost the same that of GPCC. According to the cropping calendar, the lifecycle of rice which includes five patterns in each country is obtained. Single regression analysis is used to calculate the relationships among time series of monthly precipitation datasets and yield of rice. In another words, yield of rice is a function of GPCC. Due to data limitations and variety of resolutions of datasets, we could only use country based datasets to obtain the equations. The country based rice production per unit area in each country is calculated by dividing the rice production figures provided by the Food and Agriculture Organization (FAO) by the rice cultivation area.conference pape
