Effects of daytime food intake on memory consolidation during sleep or sleep deprivation. [PDF]

, 2012
Sleep enhances memory consolidation. Bearing in mind that food intake produces many metabolic signals that can influence memory processing in humans (e.g., insulin), the present study addressed the question as to whether the enhancing effect of sleep on ...

Effect of Suction on Volumetric Yielding Behavior under Different Initial Conditions for Fine-Grained Soils [PDF]

Engineering and Technology Journal, 2013
The unsaturated soils are difficult to consider within the framework of classical (saturated) soil mechanics. In general, the unsaturated soil is stiffer than the saturated one (hardening), so the location and slope of normal consolidated line (NCL) or ...

Strength model of a cemented body based on self-compacting characteristics of tailings

Frontiers in Earth Science, 2023
To examine the strength and mechanical characteristics of self-compacting tailings, a direct shear test was conducted under various consolidation states and moisture contents to determine the cohesion and internal friction angle of the tailings.

One-dimensional creep tests and model studies on saturated saline soil

Yantu gongcheng xuebao, 2020
The physical and chemical interaction between soil particles and pore salt solutions in saturated saline soils has a strong influence on the mechanical behavior of soils, which makes the saline soils exhibit different deformation characteristics.

A Constitutive Equation of One-Dimensional Consolidation Derived from Inter-Connected Tests

Soils and Foundations, 1992
ABSTRACT In order to investigate the general relationship between void ratio e, effective stress σ' and time t at any element in a consolidating clay specimen, an inter-connected consolidometer was developed and a series of experiments on a remolded marine clay was conducted.

Characterization of large strain consolidation parameters of soft materials with time-variant compressibility at low effective stress

Soils and Foundations, 2022
The one-dimensional (1D) large strain consolidation (LSC) of saturated soft materials that are deposited at very low-density usually exhibit time-variant compressibility (void ratio vs vertical effective stress (e-σv′)) relation. The 1D column-like model

Effect of Different Sands on One-Dimensional and Hydraulic Consolidation (Radial) Tests of Clay

Iranian Journal of Science and Technology, Transactions of Civil Engineering, 2018
In settlement problems, the soil type is generally determined by the sand, silt and clay contents. Sieve analysis considers only the percentage of sand, and the grain shape of the sand is ignored. Specifically, sand grains with different characteristics are considered a single type of sand.

Characteristics of Side Friction in the One-Dimensional Consolidation Test

Soils and Foundations, 1969
SUMMARY The main purpose of this investigation is to find various factors which influence the magnitude of side friction between a soil specimen and the container wall of the one-dimensional consolidation test, and to set up suitable assumptions on which fundamental equations of the one-dimensional consolidation process affected by side friction may ...
