the modeling of kinetic and isotherm curves acquired in adsorption of polycyclic aromatic hydrocarbons (pahs) as a model compound (phenanthrene) on activated carbons in the organic solvent. all the runs were carried out in a batch system at atmospheric pressure, process temperature of 24±2°c, and using the 100 ml phenanthrene in cyclohexan. this experimental work was mainly focused on the study...

Diffusional resistance in the porous particle is important in adsorption and reaction engineering. For a porous adsorbent particle subjected to an arbitrary change in the surrounding Ž . fluid-phase concentration, Glueckauf 1955 derived the linŽ . ear driving force LDF approximation that relates the average adsorbate concentration inside the particle directly with the concentration in the fluid...

A fast-growing theoretical literature on the political economy of reform has provided a sizable collection of models that have deepened our understanding concerning how distributional conflict manifests itself in the political process and can prevent efficiency-enhancing economic reform from taking place (see e.g., Allan Drazen [2000 Ch. 10, 13] for an insightful review). Unfortunately, systema...

1st century A.D.: Celsius reported that swollen veins over the testis associated are with small testis. Mid-19th century: Inflammation of male and female reproductive organs was treated with ointments, douches and massages. 1881: Dr. Levy a German gynecologist performed a post coital test for an infertile couple and determined that the husband was sterile (no sperm on microscopic exam). Late 19...

1. introduction current statistical methods may be unable to accurately predict recurrence intervals of rare, large magnitude floods. the usual procedure involves extrapolation from gauged hydrological records documenting 30–40 year records of observed (normally small) floods to the estimation of the quantifies and recurrence intervals of very large, rare floods. this conventional approaches be...
