Development of low temperature driven DeSOx filter induced atmospheric non-equilbrium plasma for the zero emission diesel
No full textディーゼルエンジンのゼロエミッション化を目指して，大気圧非平衡プラズマ重畳による低温脱硫性能の発現ならびに無基材脱硫フィルターによる小型化を提案した．大気圧非平衡プラズマ重畳効果の明確化のため，バリア放電によるオゾン生成が脱硫性能を向上させることを明らかにした．また，無基材脱硫フィルターにより，これまでの既存フィルターより5倍程度の小型化を達成した．しかし，フィルター合成時の熱負荷によって材料利用率が低下し，熱負荷の軽減によりさらなる小型化が達成可能であることを示した．Atmospheric non-equilibrium plasma induced substrate-less DeSOx filter is proposed for improvement of low temperature activation in dry desulfulization. It was clear that low temperature desulfurization performance is improved by the generation of ozone applied barrier discharge plasma. However, in detail of mechanism why SO2 absorption performance is improved by generation of ozone is not proclaimed. in our future work, clarification of this mechanism must be investigated.
Miniaturization is achieved by substrate-less MnO2 DeSOx filter in according to remove honeycomb substrate which is occupied about half volume of DeSOx filter in comparison with conventional MnO2 DeSOx filter supported on honeycomb substrate. Its volume became 5 times smaller than conventional filter. However, this result falls short of expectations because of heat degradation of MnO2. So, more small filter can be achieved by improvement of heat treatment.研究課題/領域番号:25740031, 研究期間(年度):2013-04-01 - 2015-03-31出典：研究課題「大気圧プラズマを併用したゼロエミッションディーゼル用低温作動脱硫フィルターの開発」課題番号25740031

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Development of zero-emission diesel by micro wave induced DeSOx filter
No full text新規反応場の効果の検証ならびに，繊維状材料の新規合成法の確立による脱硫性能の向上の検討を実施した．脱硫だけでなく脱硝性能の発現の可能性を模擬排ガス中に窒素酸化物も導入して検討した．オゾン非導入時，脱硫性能は，窒素酸化物の硝酸塩化反応が阻害因子となり性能が低下した．それと同時に，脱硝性能も，硫黄酸化物の硫酸塩化に伴い阻害され性能が低下した．本結果より二酸化マンガンの脱硫脱硝性能はそれぞれの酸化物の塩化反応により阻害されることを明確にした．本フィルターにオゾンを導入し同様の検討を行った結果，オゾンによる酸化活性の向上に伴い，脱硫脱硝性能ともに向上し，特に脱硝性能は大きく向上したことを明らかにした．The potential study of novel plasma-assisted exhaust gas filter and synthesis of novel materials having low temperature activation by utilizing electron spinning method is investigated. In this year, gas purification performance including not only SOx but also NOx is evaluated to confirm the possibility of contemporaneous removal of SOx and NOx. The performance of DeSOx is reduced by NOx because of generation of nitrite. However, it is found that The performance of DeSOx and DeNOx is promoted by the existence of ozone which is generated by non thermal plasma. From this study, Plasma assist proves to be effective.研究課題/領域番号:15K16140, 研究期間(年度):2015-04-01 - 2017-03-31出典：「μ波重畳無基材脱硫フィルターによるディーゼルエンジンのゼロエミッション化」研究成果報告書 課題番号15K16140

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
ラディアル構造化プラズマ支援脱硫フィルターによるゼロエミッションディーゼルの開発
No full textディーゼルエンジンはガソリンエンジンに比べて，燃費が良く，CO2排出量が少ないため内燃機関として普及が進められている．しか し，燃焼機構の特徴から窒素酸化物 NOx や硫黄酸化物 SOx を排出してしまう問題が挙げられる．これまでMnO2を担持した脱硫フィルターを用いて移動体搭載に向けたSOx浄化技術の確立を目指してきた．浄化性能向上に向けて排ガスに大気圧非平衡プラズマを重畳させることで生成される非平衡反応 場を応用した浄化プロセスを提案した．結果として，大気圧非平衡プラズマを反応部上流に重曹してガス改質することでSO2捕集能力は向上することを明らかにした．Compared with otto cycle, diesel engines have better conversion efficiency and lower CO2 emissions, and therefore, it is becoming popular as internal combustion engines. However, there is a problem that nitrogen oxides NOx and sulfur oxides SOx are emitted due to the characteristics of the combustion mechanism. We have aimed to establish SOx purification technology for mounting on moving bodies using desulfurization filters supporting MnO2. To improve the purification performance, we proposed a purification process that applies the nonequilibrium reaction field generated by superimposing atmospheric pressure nonequilibrium plasma on the exhaust gas.As a result, it was clarified that the SO2 trapping ability is improved by the atmospheric reforming of non-equilibrium plasma with sodium bicarbonate upstream of the reactor to reform the gas.研究課題/領域番号:17K00595, 研究期間(年度):2017-04-01 - 2020-03-31出典：「ラディアル構造化プラズマ支援脱硫フィルターによるゼロエミッションディーゼルの開発」研究成果報告書 課題番号17K00595
