Effective removal of naphthalene from water using bacteria and bacteria-load carrier materials

Frontiers in Chemistry
The volatilization of naphthalene unavoidably poses significant risks to health, the environment, and safety. Traditional remediation approaches have been criticized for their inefficiency in removing naphthalene and transforming its toxicity. This study

A New Classification Method of Surrounding Rock Quality for Phyllite Tunnels Under the Condition of Layer Orientation Parallel to the Orientation of Tunnel Axis

Energy Science &Engineering, EarlyView.
Modified Mass Classification of Layered Rock Masses Based on the HC Method. ABSTRACT The HC method for hydropower is a commonly used rock mass quality classification technique in China's hydropower industry. Due to the anisotropic nature of the layered schist in the study area, and the varying angles between different tunnel layers and the tunnel axis,

Memory of Stress History in Single and Two Surface Plasticity for Granular Soils

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Recent studies have identified limitations in Manzari and Dafalias' 1997 and 2004 sand plasticity models, particularly regarding one‐way unloading/reloading and ratcheting loading modes. These models are widely accepted as bounding surface models in the geotechnical engineering community; thus, concerns have arisen about a fundamental lack of ...

Unified Permeability Modeling for Transitional Darcy/Non‐Darcy Flow Based on 3D Pore‐Level Numerical Flow Tests

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study presents a unified representation of the seepage characteristics of virtual soil, such as the transition zone from low‐velocity Darcy flow to high‐velocity non‐Darcy flow, by conducting 3D pore‐level fluid simulations. The process of defining a virtual test region as a representative volume element (RVE) and then assessing the ...

Numerical Instability in Slope Stability Analysis: A Finite Difference Approach

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT In geotechnical engineering, slice methods are the most widely used computational techniques for analyzing slope stability. Notably, the Morgenstern‐Price and Janbu approaches rigorously enforce the equilibrium of forces and moments within these slice methods.
