Plasma kinetic theory [PDF]

open access: yes, 2017
The description of plasma using fluid model is mostly insufficient and requires the consideration of velocity distribution which leads to kinetic theory.

Kinetic Parameters of Denitrification in a River Continuum [PDF]

open access: yesApplied and Environmental Microbiology, 1998
ABSTRACTKinetic parameters for nitrate reduction in intact sediment cores were investigated by using the acetylene blockage method at five sites along the Swale-Ouse river system in northeastern England, including a highly polluted tributary, R. Wiske. The denitrification rate in sediment containing added nitrate exhibited a Michaelis-Menten-type curve.

A Semi-parametric Technique for the Quantitative Analysis of Dynamic Contrast-enhanced MR Images Based on Bayesian P-splines [PDF]

open access: yes, 2008
Dynamic Contrast-enhanced Magnetic Resonance Imaging (DCE-MRI) is an important tool for detecting subtle kinetic changes in cancerous tissue. Quantitative analysis of DCE-MRI typically involves the convolution of an arterial input function (AIF) with a ...

Laccase Production from Agrocybe pediades: Purification and Functional Characterization of a Consistent Laccase Isoenzyme in Liquid Culture

open access: yesMicroorganisms, 2023
Laccases are valuable enzymes as an excellent ecological alternative for bioremediation issues because they can oxidize persistent xenobiotic compounds. The production and characterization of extracellular laccases from saprotrophic fungi from disturbed ...

Two-stream instability in quasi-one-dimensional Bose-Einstein condensates [PDF]

open access: yes, 2009
We apply a kinetic model to predict the existence of an instability mechanism in elongated Bose-Einstein condensates. Our kinetic description, based on the Wigner formalism, is employed to highlight the existence of unstable Bogoliubov waves that may be ...

Determination of the kinetic parameters of phosphofructokinase dissociation [PDF]

open access: yesFEBS Letters, 1975
It has been demonstrated that phosphofructokinase from rabbit skeletal muscle is dissociated into inactive subunits in the presence of low enzyme concentrations ]I] I Dissociation constants of about 10e6 M, as estimated from computer simulations [2-S], suggested physiological significance of the dissociation process in the regulation of cellular ...
