EROSION RATE FORMULA OF COHESIVE SEDIMENT
Doboku Gakkai Ronbunshuu B, 2009 本研究では，砂と粘土と水からなる土砂を「粘着性土」と定義し，その浸食過程の解明と浸食速度予測式の誘導とを目的として，一連の実験的検討を行った．この浸食速度に影響を与える要因としては，作用せん断力あるいは摩擦速度，水温ならびに水含有率が特に支配的であることがわかり，その各々の影響について定量的な評価を行った．また，こうした成果を踏まえて浸食速度式を誘導し，その妥当性の検証も行った．以上の量的な検討に加えて，本研究では，画像解析などを通じて粘着性土が浸食を受けるプロセスにも注目し，通水初期において供試体表面に微細な擾乱が形作られ，時間の経過と共にこれが波状の凹凸へと成長することも明らかにした．

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Modeling sunspot and starspot decay by turbulent erosion [PDF]
, 2015 Disintegration of sunspots (and starspots) by fluxtube erosion, originally proposed by Simon and Leighton, is considered. A moving boundary problem is formulated for a nonlinear diffusion equation that describes the sunspot magnetic field profile ...

Advanced Engineering Materials, EarlyView.Disordered (Fe50Co50)1−xPtx thin films exhibit a pronounced anomalous Nernst effect (ANE) with a strong composition dependence on both rigid and flexible substrates. The transverse thermoelectric response peaks near 22.5 at.% Pt, accompanied by enhanced αxy/σxy scaling, thermal transport, and ANE sensitivity.

Advanced Engineering Materials, EarlyView.The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...
