Determination of Soil-Water Characteristic Curves of Unsaturated Sandy Soils Using Membrane Filter with Stainless Wire Mesh

, 2009
Soil-water characteristic curve (SWCC) is an important soil function in an unsaturated soil mechanics field for design and analyses of any unsaturated earth structures. Determination of SWCC is not easy and more so time consuming. Generally, ceramic disc

A Review on the Resilient Response of Unsaturated Subgrade Soils

Advances in Civil Engineering, 2020
Considering the great contribution of subgrade modulus to the overall performance of roads or railways, it is crucial to provide the best prediction of resilient modulus for their foundations. Incorporating the seasonal variation of moisture content, the

Unsaturated shear strength characteristics of coarse-fine mixed soils in a wide range of degree of saturation: experimental phenomena

Yantu gongcheng xuebao, 2023
The coarse-fine mixed soils are widely distributed in natural and geotechnical engineering practices. Their strength is vital to the stability of geotechnical engineering (e.g., slopes, foundation pits and retaining walls). However, the unsaturated shear

Equations for soil freezing characteristics curves based on the thermodynamics principles

Geoderma, 2023
Experimental studies related to the thermo-hydro-mechanical-chemo (THMC) behaviors of unsaturated frozen soils are cumbersome, expensive, and time consuming.

Prediction of wetting-induced volume change behaviour of compacted unsaturated soils in the context of the MPK framework

E3S Web of Conferences, 2016
Compacted unsaturated soils show distinct behavioural patterns when compared with their saturated counterparts, and these behavioural patterns become more and more complex when soil is subjected to wetting, such as swelling or collapse and loss of shear ...

Hydro-mechanical coupling bounding surface model for unsaturated soils considering bonding effect of particles

Yantu gongcheng xuebao, 2020
The interparticle bonding effect has a significant influence on the hydro-mechanical coupling characteristics of unsaturated soils. Establishing a constitutive model for unsaturated soils considering the bonding effect is of great significance for ...

Bearing Capacity of Shallow Foundations on Unsaturated Silty Soils

Applied Sciences, 2023
In general, the ultimate bearing capacity (UBC) of shallow foundations on unsaturated soils is characterized by the conventional shear strength (SS) parameters in which saturated theories are applied.

Nanocellulose Alleviates Intrahepatic Cholestasis of Pregnancy via Gut Microbiota‐Mediated Bile Acid Homeostasis

Advanced Science, EarlyView.
Nanocellulose, derived from microcrystalline cellulose (MCC) through sulfuric acid hydrolysis or mechanical grinding to produce CNC or CNF, was tested in a rat ICP model. Particularly, CNF improved gut microbiota composition, reduced secondary bile acid metabolism, and restored bile acid homeostasis through modulation of the gut–liver axis.

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

Archaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...
