In Japan, the introduction of a carbon tax with higher rates than the current level is planned by around 2028. A carbon tax is a policy mechanism that imposes a levy on CO₂ emissions from various indu [...]

大型鋼構造物の建造工程導入に向けたレーザ・アークハイブリッド溶接技術の適応範囲拡張に関する検討

Department of Civil and Structural Engineering, Graduate School of Engineering

現在の溶接技術において大入熱溶接に伴う変形や機械的性質の劣化は喫緊なる課題である．本課題を解決する新溶接技術として，レーザ溶接法とアーク溶接法を組み合わせたレーザ・アークハイブリッド溶接法が存在するが，その研究内容や実用化の多くは下向の溶接姿勢に限られる．生産現場のニーズを考慮すれば横向や立向などの溶接姿勢にも対応できることが望ましい．本研究はハイブリッド溶接施工法の適応範囲拡張に関する内容である [...]

海洋における昆虫の“海流分散による分布拡大”に対する新たなアプローチ〜昆虫の海水耐性が遺伝的交流に与える影響と”浮遊分散”の可能性〜

Department of Integrated Sciences for Global Society, Graduate School of Integrated Sciences for Global Society

海流分散は、生物が海流に乗り漂着先で繁殖し生息地が広がることを指し、島嶼地域では他の分散方法に比べ、その頻度は高いと考えられ、生物相の成立考えるうえで重要な要素となる。しかし、既存の昆虫の海流分散に関する研究は、分子集団遺伝学的解析によるものばかりで他指標を用いて海流分散を示唆した研究は少ない。したがって、本研究では、海水耐性という新たな指標から昆虫の分布形成に対する海流の影響を評価する。

DNA, the genetic material, is damaged by endogenous as well as exogenous sources such as base alkylating chemicals. Some alkylating reagents produce O-6-methylguanine (O6mG), which induces cell death, [...]

High strength steels with the strength of 1GPa or more have been used for the automotive body structure. Increasing requirements for crashworthiness and energy conservation have led to the demand for [...]

Elucidation of the vegetation history of post-war afforestation and examination of suitable sites for reforestation using agricultural and forestry statistics

Department of Agro-environmental Sciences, Graduate School of Bioresource and Bioenvironmental Sciences

This study attempted to reconstruct the vegetation history of post-war afforested plantations throughout the country at the level of former municipalities using GIS (Geographic Information System) and [...]

This research deals with Transformational theory that incorporates the concept of mathematical group theory and, in relation to it, focuses on Tonnetz (tone-network), geometrical models utilized in mu [...]

The purpose of this research is to create novel sialidase inhibitors. We found that slightly modified sialic acids exhibited much stronger sialidase inhibitory activity than known inhibitors. This fin [...]
