Metathetic Polymerisation of Cyclic Alkenes
… and tungsten hexachloride and that the kinetic behaviour of the system and the products of the reaction depended on the solvent used. The kinetic behaviour of WC16/ cyclopentene system in toluene was complex; the dependence of the rate of polymerisation on the concentration of tungsten …

DEVELOPMENT OF GAS KINETIC FLUX SOLVERS AND THEIR APPLICATIONS
In this thesis, a series of novel gas kinetic flux solvers (GKFSs) have been developed and applied to solve a variety of flow problems. Firstly, two types of GKFSs have been successfully proposed for both inviscid and viscous flow simulations. The developed solvers have been validated in a variety …

Halo enol lactone and protio enol lactone inhibitors of alpha-chymotrypsin: Mechanism and stereospecific behavior of inhibition
A kinetic study of inactivation of $\alpha$-chymotrypsin by enol lactones was performed. Halo enol lactones, 3-(1-naphthyl)-6(E)-(iodomethylene)tetrahydro-2-pyranone ($\alpha$Np6I) and 3-phenyl-6(E)-(bromomethylene)tetrahydro-2-pyranone ($\alpha$Ph6Br), showed burst kinetics in the inactivation of …

Kinetic studies of the metathesis of 1-hexene using Re2O7/γ-Al2O3 and the synthesis and metathesis of oxazolines
The kinetics of the metathesis of 1-hexene using Re2O7/-Al_2O_3 as the catalyst were investigated under a variety of conditions. The experiments were carried out under high vacuum conditions. The product solutions were characterised by gas liquid chromatography and mass spectroscopy. The initial …

The effects of natural convection on low temperature combustion
… → B, in the presence of natural convection. This kinetic scheme is used as a simplified representation of a cool flame, which is a feature of the low temperature combustion of a hydrocarbon vapour. Sal’nikov’s reaction is one of the simplest to display thermokinetic oscillations, such as those …

Quantum Yields And Mechanism In Titanium Dioxide Mediated Photocatalysis
… a spin trap/EPR technique within a competition kinetic scheme. Experimental results from competition reactions indicate that there is a marked difference in kinetic behaviours between the systems with (heterogeneous) and without (homogeneous) a TiO{dollar}sb2{dollar} suspension, which confirms …

Analysis of antioxidant behaviour in lubricating oils
… concentration of the additive being analysed. A kinetic analysis of an antioxidant by CV leads to information about the diffusion coefficient of the molecule and the rate of electron transfer at the electrode surface. It was found that the electrochemically oxidised species of the amine …

Phenomenological models of motor proteins
… of the link. By proposing a new modeling scheme, we devise a unified description of such experiments for various motor proteins. This description is based on the picture that the motor thermal fluctuations are rectified in a preferred direction by means of barriers whose heights are …

Fundamental studies of premixed combustion
… considers a one dimensional flame using a full kinetic scheme. Data from the present experiments and computations are compared with those reported elsewhere. Comparisons are made with iso-octane-air mixtures and the contrast between fuels lighter and heavier than air is emphasized. Flame …

Measurement and Interpretation of Moments of the Combined Hadronic Mass and Energy Spectrum in Inclusive Semileptonic B-meson Decays
… quark parameters. Using HQE calculations in the kinetic scheme up to order 1/m_b^3 we find |V_{cb}| = (41.65 +- 0.43 +- 0.40 +- 0.58) x 10^{-3} and m_b = (4.570 \pm 0.033 \pm 0.043)GeV/c^2, where the first uncertainty refers to experimental contributions, the second to uncertainties in the HQE, …

Mathematical modelling of premixed laminar methane-air flames
… model made use of a number of reduced chemical kinetic schemes, with realistic elementary reactions. These were drawn from the literature and realistic transport properties have been included. With this model, based on the work of Peters (1985), the effects of stretch are automatically accounted …

BIO-MATHEMATICS: INTRODUCTION TO THE MATHEMATICAL MODEL OF THE HEPATITIS C VIRUS
<p>In this thesis, we will study bio-mathematics. We will introduce differential equations, biological applications, and simulations with emphasis in molecular events. One of the first courses of action is to introduce and construct a mathematical model of our biological element. The biological …
