A SIMPLIFIED PRACTICAL METHOD FOR EVALUATING LIQUEFACTION-INDUCED FLOW
Doboku Gakkai Ronbunshu, 1999 液状化に伴って生じる地盤の流動を線形の有限要素法により簡易的に評価する手法を提案している. 流動を液状化後ゆっくりと生じる現象と想定し, 繰返しせん断応力を加えて液状化させた後単調に載荷させる実験を行い, 液状化後の砂の応力-ひずみ関係を求めたところ, 剛性が非常に小さい, 微小抵抗領域とその後の剛性回復領域に分けられることが分かった. これらをそれぞれ線形の関係に置くことで, 簡易解析に用いる砂の応力-ひずみ関係をモデル化した. さらに, 液状化層上部の非液状化層やケーソン直下の地盤についても線形の応力-ひずみ関係にモデル化する方法を提案した. これらを用いて, 地震被害解析を行ったところ, かなりの精度で実被害を説明できることが分かった.

Study on Natural Gas Decarbonization Process Based on CO2 Desublimation Characteristics
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Natural gas decarbonization is a crucial processing step. In this study, the snow separation technology for removal of carbon dioxide in natural gas based on CO2 desublimation characteristics was introduced. The phase equilibrium calculation of CH4‐CO2 and N2‐CO2 system was carried out by using cubic equations of states (EOSs), and identified ...

Clinical periodontal diagnosis
Periodontology 2000, EarlyView., 2023 Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...

Pilot-Scale Continuous-Flow Hydrothermal Liquefaction of Filamentous Fungi
Energy & Fuels, 2016 This study examined the potential of using the filamentous fungus Rhizopus oligosporus as a feedstock for hydrothermal liquefaction (HTL). The fungal biomass, cultivated in thin stillage from a corn ethanol plant, was processed at pilot-scale using a 1.5-L capacity continuous-flow HTL system.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...
