Abstract:

Stormwater runoff from urbanized areas can have detrimental impacts on groundwater and surface water supplies by mobilizing contaminants such as bacteria and nutrients from surrounding areas. Best Management Practices (BMPs) are commonly designed to mitigate these impacts, but the processes governing the effectiveness of these BMPs are often not well understood. Biofiltration BMPs, which include storage, sediment removal, and infiltration processes, are particularly challenging to quantify. This research involved an investigation of the processes associated with a biofiltration BMP located in

Abstract:

Dynamic response of materials to high-speed and high-intensity loading conditions is important in several applications including high-speed flows with droplets, bubbles and particles, and hyper-velocity impact and penetration processes. In such high-pressure physics problems, simulations encounter challenges associated with the treatment of material interfaces, particularly when strong nonlinear waves like shock and detonation waves impinge upon them. To simulate such complicated interfacial dynamics problems, a fixed Cartesian grid approach in conjunction with levelset interface tracking is a

Abstract:

The marine hydroid Garveia annulata is a small, brightly colored coelenterate whose crude methanol extracts exhibit potent antibacterial and antifungal activity. The compounds responsible for this biological activity were purified and characterised as a series of related 1-[4H]-anthracenone derivatives. Twenty one metabolites have been isolated and their structures were elucidated by using a combination of spectral analysis, chemical interconversions, synthesis and single crystal X-ray diffraction analysis. The structure of garveatin A (77), the major metabolite, was determined via a series o

Abstract:

The catastrophic fragmentation of finite targets is examined both in the laboratory and using a numerical hydrocode. The objective of the empirical study was to gain some insight into the collisional process, specifically, how impact conditions affect collisional outcome. The hydrocode allows us to investigate the fragmentation of large bodies, and to determine how target size influences the impact event. Nearly 150 experiments were performed for this study. Impact velocities ranged from 50-5700 m/s; target material/structure as well as projectile type were varied, and the effect on fragment m

There are many questions associated with the understanding of the origin and regulation of bioluminescence. A key question underlying this thesis was why coelenterazine evolved as the most common marine luciferin. Another problem addressed was the coelenterazine source of the bioluminescent hydroid Obelia, which is unknown. Coelenterazine is an integral part of Obelia’s photoprotein, triggered by Ca2+. The thesis also investigated the uncertainty over how Ca2+ enters Obelia’s photocytes. Obelia is considered to have four species, but they have been misidentified. Green fluorescent protein (GFP

Eudendrium may be a shelf genus avoiding turbulent oceanic waters. Species of Eudendrium are predominantly epizoic and some gregariously settling colonies may live for five years. Identification of sterile material is refined by using the cnidome in a key to classification. The species

Abstract:

Master´s thesis is focused on development of electrodes used in alcaline accumulators, by using new kinds of materials and compounds. Basic possitive eletrode was made of nickel, on this electrode were applied new layers of Ni(OH)2 by using the method called electrodeposition. For electrodeposition was used solution with Ni(NO3)2 in diverse concentrations. Later on, this material was enriched with aluminium admixtures to increase stability of alfa modification in Ni(OH)2. These concentrations were measured and analysed in diagrams. For measurement was used device Biologic. The diagrams were co
