The objective of this study was to develop a method for analysis of MGF in tear fluid that can be further utilised to evaluate the kinetics of pre-cornea drug concentration. For sample collection, lacrimal tear fluid was absorbed into pre-weighed absorbing paper strips, which were then immediately weighed again right after sampling to calculate the sample mass.

Hepatitis B infection remains a global health problem, with progression to acute-chronic hepatitis, severe liver failure, and death making hepatitis B one of the most serious infections worldwide. The disease is most widely transmitted from an infected mother to her baby, after exposure to infected blood or body fluids or unsafe sexual contact.

A Abatement: Reducing the degree or intensity of, or eliminating, pollution. Abatement Debris: Waste from remediation activities. Absorbed Dose: In exposure assessment, the amount of a substance that penetrates an exposed organism's absorption barriers (e.g.,, skin, lung tissue, gastrointestinal tract) through physical or biological processes. The term is synonymous with internal dose. Absorption Barrier: Any of the exchange sites of the body that permit uptake of various substances at different rates (e.g., skin, lung tissue, and gastrointestinal-tract wall).

Thermophysical properties of industrially complex fluids whose composition is always ill-defined are in practice predicted by using thermodynamic models. To ensure the prediction accurately and reliably, a three-step procedure to obtain the properties of these fluids must be validated. The focus of this study is laid on a short review of tools which can be served for each of the three steps.

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 purpose of this project is to enable the prediction of flow behaviour of concentrated slurries in the pipe loop under various laminar flow conditions using the fluid analogue to slurry and to find the suitable rheological model from the literature for the fluid analogue and tailings from the Sunrise dam. The major objective of the project is to develop a fluid analogue which will have similar rheological behaviour to that of the tailings from Sunrise dam so that it can be used as a test material to predict the flow behaviour of tailings in a pipe.

The main objective of this research is to optimize the design of the Tunnel kiln for efficient fuel usage. To achieve that, the temperature distribution from the simulation needs be matched with the desired Tunnel kiln curve found in industry. This objective can be achieved by CFD simulation where temperature, velocity and emission distributions inside the Tunnel kiln can be obtained. Generated temperature distribution can be matched with the industrial curve and by interpreting the curve, efficient design can be suggested.

The aim of this research is to employ a sensitivity study for the total thrust of a ducted twin counter-rotating propeller system design for UAV applications using computational fluid dynamics (CFD). Two factors were investigated: propeller spacing and difference between blades pitch angle. Using discrete values for both factors, 32 designs were analysed and evaluated. The same approach was also used for an equivalent unducted propeller system to access the influence of the duct.
