The recovery and removal of the most organic acids in liquid solutions is usually treated with fixed-bed adsorption processes. Among many adsorbents, Granular Activated Carbon (GAC) is used to remove organic pollutants such as Benzoic Acid (BA) from wastewaters conventionally. In this research, adsorption isotherm curves of BA onto GAC at varying temperatures 25-60 °C are developed and the ...

This paper introduces a distributed call admission controller for ad hod networks. The call admission controller is based on service curve provisioning. Service curve reflects the status of network and depends on the number of active nodes, their activity index, and the back-off procedure used for contention resolution. The service curve along with the aggregated traffic function can be used to...

The rating curve is the relationship between the water stage and the associated discharge in a givensection of a channel. In steady flow, this relationship usually has exponential type, whereas inunsteady it flow has a looped shape. Since direct developing of actual looped rating curve by usinghydrometric methods is merely possible, steady-state rating curve is commonly used as a downstreamboun...

An effective analytical approach without Monte Carlo simulation was previously presented by the U.S. Army (Ref. [1]) to evaluate fatigue reliability of helicopter dynamic components. This analytical approach required selection of a reference S/N curve for damage evaluation. Overall reliability of a given life was based on the assumption of weighted sums of the equivalent damage rates of all ste...

A phenomenological model based on the three-dimensional theory of nonlinear elasticity is developed to describe the phenomenon of overstretching in the force-extension curve for dsDNA. By using the concept of a material with multiple reference configurations a single formula is obtained to fit the force-extension curve.

Although it is believed that normal thyroid hormone levels are set points, representing individually pre-determined reference levels, in this paper, we discuss how analysis of the population distribution of Free Thyroxine/ Thyroid Simulating Hormone (FT4/TSH) levels supports a model of homeostasis in which these levels represent the equilibrium points of the physiologic processes of homeostasis...

For the dose study, a semi-automated method of data collection is used in this study. The participating centres were asked to fill out a spreadsheet with all necessary data and return it. For direct digital (DR) systems, the relevant data available in the DICOM header were used. All data is automatically added to a database and processed. The data were used to calculate the mean glandular dose ...
