The Characteristic Curve Method in Adsorption

Water Retention and Characteristic Curve

A soil-water characteristic (SWC) curve describes the amount of water retained in a soil (expressed as mass or volume water content, m or v) under equilibrium at a given matric potential. An SWC is an important hydraulic property, related to size and connectedness of pore spaces, hence strongly affected by soil texture and structure, and by other constituents, including organic matter. Modeling...

Evaluation of the Efficiency of Some Mitochondrial Function Biomarkers in the Differential Diagnosis of Autism Spectrum Disorder Using Performance Characteristic Curve (ROC) Analysis Method

Background & Aims: Autism disorder is a neurodevelopmental disorder whose symptoms are mainly in the early months of life, especially between 12 and 24 months and in general, up to 3years of age, and due to severe and persistent deficiencies in communication and interactions. Social, communication skills, limited, inflexible, and repetitive patterns appear in behavior, activities, and interests...

Equations for the soil-water characteristic curve

The soil-water characteristic curve can be used to estimate various parameters used to describe unsaturated soil behaviour. A general equation for the soil-water characteristic curve is proposed. A nonlinear, least-squares computer program is used to determine the best-fit parameters for experimental data presented in the literature. The equation is based on the assumption that the shape of the...

Characteristic Points of Stress-Strain Curve at High Temperature

Determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. In this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. The critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. In a...
