Modelling of collapse settlement by effective stress and shear strength interaction for granite residual soil / Ismacahyadi Bagus Mohamed Jais [PDF]

open access: yes, 2014
Over the years, consolidation settlement has always been associated with effective stress increase. However, in unsaturated soils, volume change behaviour of soils due to wetting is always complex due to changes of the soil when it is inundated. The main

Experimental Study on Determining Unsaturated Property of Soil [PDF]

open access: yes, 1980
This paper deals with the experimental study of hydraulic properties of unsaturated soil. In treating unsaturated zone, a great deal more data are required than are required for the saturated zone, but these properties of soils must be known to apply the

Unraveling Synergistic Regulation Mechanism in Nitrogen/Sulfur Co‐Doped Biomass‐Derived Hard Carbon Toward Durable Sodium‐Ion Battery Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nitrogen/sulfur co‐doping optimizes the electron and spatial structure of biomass‐derived hard carbon, and the anode demonstrates superior long‐term cycling stability over 2000 cycles, validating an improved “adsorption‐intercalation‐pore filling” mechanism.

Investigation of the Water-Retention Characteristics and Mechanical Behavior of Fibre-Reinforced Unsaturated Sand

open access: yesApplied Sciences, 2023
The introduction of fibres into soil can effectively improve its engineering properties. Systematically understanding the unsaturated mechanical properties of fibre-reinforced soil is highly significant. Moreover, there is currently no suitable model for

Buck Wheat: Nutritional, Bioactive Characteristics, Health Benefits, and Side Effects

open access: yesFuture Postharvest and Food, EarlyView.
ABSTRACT Micronutrient deficits have resulted from an over‐reliance on a small number of cereal crops for food security. The agricultural sector faces severe sustainability issues due to the rapid growth of the world's population and sudden climatic changes.

Stability of 3D tunnel face under steady unsaturated seepage coupled multi-layer soil suction head distributions

open access: yesAlexandria Engineering Journal
This paper proposes a new discrete approach for analyzing tunnel face stability in stratified soils under unsaturated seepage conditions. Traditional methods have primarily focused on homogeneous soils, neglecting the spatial variability of unsaturated ...

Amplitude Domain Reflectometry法による不飽和砂地盤中のNAPL含有量と誘電率に関する基礎的研究 [PDF]

open access: yes, 2008
Subsurface contamination by non-aqueous phase liquid (NAPL) has become a serious environmental issue. Therefore, it is necessary to estimate the NAPL content (θNAPL) in unsaturated soil to detect and monitor the NAPL contaminations in soil and ...

Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

open access: yesJournal of Quaternary Science, EarlyView.
Abstract The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...
