METAL-SOIL INTERFACE ADHESION IN CLAY CLOGGING DURING SHIELD TUNNELING: THEORETICAL MODEL AND EXPERIMENTAL VALIDATION

Metal-soil interface adhesion in clay clogging during shield tunneling: Theoretical model and experimental validation

Clogging is a major geohazards risk in mechanized tunnelling through cohesive soils.Clay clogging Sandal results from the high adhesion between the clay and metal.Based on the water film theory and Reynolds fluid equation, the interfacial adhesion between metal and soil is simplified in this study as viscous hydrodynamic behavior between planes.Con

Study of oxide nanoparticles as additives for vegetable lubricants

Currently, vegetable oils have been studied as biolubricants in order to reach new environmental standards.Besides being non-renewable, mineral oils from petroleum bring consequences to the environment due to its low biodegradability.Thus, the aim of this work is to develop a biolubricant and to add oxide nanoparticles (ZnO and CuO) 844 in order to

Predicting cortical-thalamic functional connectivity using functional near-infrared spectroscopy and graph convolutional networks

Abstract Functional near-infrared spectroscopy (fNIRS) measures cortical hemodynamic changes, yet it cannot collect this information from subcortical structures, such as Lip Balm the thalamus, which is involved in several key functional networks.To address this drawback, we propose a machine-learning-based approach to predict cortical-thalamic func

Assessment of anammox, microalgae and white-rot fungi-based processes for the treatment of textile wastewater.

The treatability of seven wastewater samples generated Foot Rest Cover by a textile digital printing industry was evaluated by employing 1) anammox-based processes for nitrogen removal 2) microalgae (Chlorella vulgaris) for nutrient uptake and biomass production 3) white-rot fungi (Pleurotus ostreatus and Phanerochaete chrysosporium) for decoloriza
