Analysis of flow

The increasing use of Intelligent Transport System (ITS) can enable very close vehicle spacings which generally results in a net drag reduction for the resulting convoys. The majority of vehicle development has, to date, been for vehicles in isolation, thus the study of interaction effects is becoming increasingly important. The main objective of this research is to investigate the use of Computational Fluid Dynamics (CFD) for understanding convoy aerodynamics and to further the understanding of airflow interaction between vehicles via CFD.

This study aims to use CFD analysis of CT scan data from the nasal cavities of a range of older Asian males to investigate the impact of geometric variations between older nasal cavities on the airflow structures and airconditioning capacity of the nasal cavity. Air flow mechanisms, heat transfer rates and humidification efficacy are analysed in order to arrive at a more precise understanding of the role of nasal geometry in the presentation of respiratory ailments.

The thesis concentrates on measuring the benefits and losses of implementing regional trade agreements. In particular, the thesis analyses trade flow changes, foreign direct investment inflow changes, industrial total factor productivity changes and specific commodity trade flow changes in Australia and China. Four empirical studies are undertaken.

Trade and world economic integration are seen as the impetus for accelerating the well-beings of the domestic Vietnamese communities and international community in the region. However, an understanding of the link between trade and economic integration from the perspective of Vietnam is missing. Empirical studies on Vietnamese trade are in lack to address these determinants (see, Le, 1996; Nguyen, 2010). This thesis identifies the key factors that have driven the impressive growth of Vietnamese exports during the world economic integration process (1986-2010).

Penicillin acylase catalyses the hydrolysis and synthesis of semisyntheticb-lactam antibiotics via formation of a cova-lent acyl-enzyme intermediate. The kinetic and mechanistic aspects of these reactions were studied. Stopped-flow experiments with the penicillin and ampicillin analogues 2-nitro-5-phenylacetoxy-benzoic acid (NIPAOB) and D-2-nitro-5-[(phenylglycyl)amino]-benzoic acid (NIPGB) showed that the rate-limiting step in the conversion of penicillin G and ampicillin is the formation of the acyl-enzyme....

The roles of His181, His184 and Tyr186 in PETN reductase have been examined by mutagenesis, spectroscopic and stopped-flow kinetics, and by determination of crystallographic structures for the Y186F PETN reductase and reduced wild-type enzyme—progesterone complex. Residues His181 and His184 are important in the binding of coenzyme, steroids, nitro-aromatic ligands and the substrate 2-cyclohexen-1-one.

Purified recombinant proteins fromSynechocystisPCC6803 were used to show that the magnesium chelatase ChlH subunit stimulates magnesium protoporphyrin methyltransferase (ChlM) activity. Steady-state kinetics demonstrate that ChlH does not significantly alter theKmfor the tetrapyr-role substrate. However, quenched-flow analysis reveals that ChlH dramat-ically accelerates the formation and breakdown of an intermediate in the catalytic cycle of ChlM.

Inorder to clarify the role of cytochrome innitrate reductase we have performed spectrophotometric and stopped-flow kinetic studies of reduction and oxidation of the cytochrome hemes with analogues of physiological quinones, using menadione as an analogue of menaquinone and duro-quinone as an analogue of ubiquinone, and comparing the results with those obtained with dithionite. The spectropho-tometric studies indicate that reduction of the cytochrome hemes varies according to the analogue of quinoneused, and in no cases is it complete....

Activation of coagulation factor X (fX) by activated factors IX (fIXa) and VIII (fVIIIa) requires the assembly of the enzyme–cofactor–substrate fIXa– fVIIIa–fX complex on negatively charged phospholipid membranes. Using flow cytometry, we explored formation of the intermediate membrane-bound binary complexes of fIXa, fVIIIa, and fX.

CD98 heavy chain (CD98hc), expressed at high levels in developing human trophoblasts, is an integral membrane protein with multiple N-linked gly-cosylation sites and known to be important for cell fusion, adhesion, and amino acid transport. Western blotting and flow cytometry were used to study the effect of brefeldin A, an inhibitor of protein translocation through the Golgi, on CD98hc in the human placental trophoblast cell line BeWo.

Heterogeneities in tumor blood flow are associated with cyclic changes in pO2 or cyclic hypoxia. A major difference from O2 diffusion-limited or chronic hypoxia is that the tumor vasculature itself may be directly influ-enced by the fluctuating hypoxic environment, and the reoxygenation phases complicate the usual hypoxia-induced phenotypic pattern.

FoF1-ATP synthase (FoF1) synthesizes ATP in the F1 portion when pro-tons flow through Fo to rotate the shaft common to F1 and Fo. Rotary synthesis in isolated F1 alone has been shown by applying external torque to F1 of thermophilic origin.

We present an analysis of bounded-energy low-tension maps between 2-spheres. By deriving sharp estimates for the ratio of length scales on which bubbles of opposite orientation develop, we show that we can establish a ‘quantization estimate’ which constrains the energy of the map to lie near to a discrete energy spectrum. One application is to the asymptotics of the harmonic map flow; we find uniform exponential convergence in time, in the case under consideration.

Proteomic analysis requires the combination of an extensive suite of tech-nologies including protein processing and separation, micro-flow HPLC, MS and bioinformatics. Although proteomic technologies are still in flux, approaches that bypass gel electrophoresis (gel-free approaches) are domi-nating the field of proteomics.

The antiproliferative effect of the Hsp90 inhibitor 17-AAG (17-allylamino-17-demethoxygeldanamycin) on human retinal pigment epithelial cells is investigated. Methods: MTT and flow cytometry were used to study the antiproliferative effects of the 17-AAG treatment of ARPE-19 cells. 2D gel electrophoresis (2-DE) and mass spectrometry were applied to detect the altered expression of proteins, which was verified by real-time PCR.
