Hexavalent chromium, a highly toxic metal ion employed in industrial activities, is considered as a first priority pollutant. In this study, the capsule walls of the boll of cotton (cotton waste, CW) and the waste obtained from pruning barberry bushes (barberry waste, BW) were investigated as cheap and locally available adsorbents for Cr (VI) removal. The adsorption behavior, equilibrium, and k...

PURPOSE the aim of this article was to review the clinical approach of quadriceps strengthening programmes. METHODS a literature search was carried out from 1980 up to September 2011. Eligible studies were those that: (1) evaluated the patients with patellofemoral pain syndrome (not healthy or asymptomatic subjects) (2) examined the effect of kinetic chain exercises (3) examined the effect of...

In this paper, first, we present a kinetic data structure for the problem of kinetic convex hull maintenance. After that, discuss some complicated cases followed by the main algorithm and two additional algorithms. Finally, focus on the evaluation of the four properties of the kinetic algorithm in the worst case. We show that quality factors of our algorithm are at most linear. Comparing with s...

The kinetic models are fundamental knowledge about biochemical and microbial processes. The object of the work is the kinetic model researching based on the biochemical and microbial mechanisms of cell growth, substrate consumption and product formation. The ethanol biosynthesis process as fuel from renewable resources is the engineering goal. The engineering goal requires the inclusion of the ...

A kinetic model for droplet heating and evaporation into a high pressure background gas (air) is described. This model is based on the introduction of the kinetic region around evaporating droplets, where the dynamics of molecules are described in terms of the Boltzmann equations for vapour and air. Both mass and heat transfer processes in this region are taken into account. The conditions at t...

The most general Lagrangian for a model with two U(1) gauge symmetries contains a renormalizable operator which mixes their gauge kinetic terms. Such kinetic mixing can be generated at arbitrarily high scales but will not be suppressed by large masses. In models whose supersymmetry (SUSY)breaking hidden sectors contain U(1) gauge factors, we show that such terms will generically arise and commu...

Dynamic PET, in contrast to static PET, can identify temporal variations in the radiotracer concentration. Mathematical modeling of the tissue of interest in dynamic PET can be simplified using compartment models as a linear system where the time activity curve of a specific tissue is the convolution of the tracer concentration in the plasma and the impulse response of the tissue containing kin...

In this study, we develop and test a method to determine the rate of particle transfer and kinetic isotope effects in enzymatic reactions, specifically yeast alcohol dehydrogenase (YADH), from first-principles. Transition path sampling (TPS) and normal mode centroid dynamics (CMD) are used to simulate these enzymatic reactions without knowledge of their reaction coordinates and with the inclusi...
