The Use Of Prebiotics To Improve Fish Health, Michelle Stone Jan 2005

The Use Of Prebiotics To Improve Fish Health, Michelle Stone

School of Biological and Marine Sciences Theses

The aim of this project was to analyse critically the potential use of prebiotics in aquaculture. Initially, the intestinal microflora of rainbow trout, raised in the aquarium facilities at CEFAS, Weymouth, was investigated using both conventional bacteriological (culture, BiOLOG) and molecular (Restriction Fragment Length Polymorphism (RFLP), 16S rRNA gene sequencing) techniques. Dominant colony types were identified as Aeromonas sobria, Carnobacterium piscicola and Clostridium gasigenes. A series of in vitro growth curve studies was carried out using a selection of intestinal bacteria and known fish pathogens, to determine the ability of intestinal bacteria to utilise the potential prebiotic candidates inulin, lactulose …

Molecular Resolution Of Marine Nematodes For Improved Assessment Of Biodiversity, Punyasloke Bhadury Jan 2005

Molecular Resolution Of Marine Nematodes For Improved Assessment Of Biodiversity, Punyasloke Bhadury

School of Biological and Marine Sciences Theses

Free-living nematodes are abundant in all marine habitats, highly diverse and can be important ecological indicators for monitoring anthropogenic impacts on the environment. Despite such attributes, nematode diagnostics has traditionally relied on detailed comparison of morphological characters which is often difficult and laborious, and as a result there is an increasing 'black hole' in faunal inventories where the biodiversity of groups such as nematodes is typically underestimated. Molecular methods offer a potentially efficient alternative approach to studying the biodiversity of marine nematode communities, and the main focus of this thesis was to apply molecular ecological tools for improved understanding of …

Effect Of Human Disturbance On The Foraging Behaviour Of The Oystercatcher Haematopus Ostralegus On The Rocky Shore, Sarah Carless Jan 2005

Effect Of Human Disturbance On The Foraging Behaviour Of The Oystercatcher Haematopus Ostralegus On The Rocky Shore, Sarah Carless

School of Biological and Marine Sciences Theses

The aim of this thesis was to investigate the effects of human disturbance on animal foraging behaviour using oystercatchers foraging on the rocky shore as a model system. The primary focus of this thesis was the balance between vigilance and foraging, and the variation in this balance with changes in environmental factors and the application of experimentally controlled human disturbance. On the structurally complex rocky shore foraging and vigilance are generally mutually exclusive behaviours and so an individual must trade-off energy acquisition with predator avoidance. The extent of the trade-off was expected to vary spatially and temporally dependant upon an …

Ammonia Emissions From Slurry Applications To Land, Thomas Henry Misselbrook Jan 2005

Ammonia Emissions From Slurry Applications To Land, Thomas Henry Misselbrook

School of Biological and Marine Sciences Theses

Over the last 10-15 years there has been increasing concern within Europe as to the effects of ammonia emission and subsequent deposition to sensitive ecosystems, causing eutrophication and soil acidification. Transboundary transport of emissions has led to legislation at EC level with member states being given emission ceiling targets. Research has therefore aimed at quantifying national emissions, modelling emission processes and developing mitigation strategies. Agriculture accounts for >80% of total UK ammonia emission, therefore an accurate and robust model is required to estimate emissions from this sector. National inventory methodology has improved as the database of emission measurements and survey …

Turkish Journal of Medical Sciences

Bioluminescent imaging (BLI) is particularly well suited for imaging small animals, and it can be readily used by scientists who are already routinely using the luciferase gene as a reporter in cell-based assays. This strategy relies on ATP and an O_2 dependent photochemical reaction between luciferin and luciferase, resulting in the release of photons from only live cells. In BLI, the intensity of the light detected by the device is proportional to the intensity of light emitted and the relationship is quantitative. This study was performed to determine the sensitivity of BLI for the imaging of lung metastasis and breast …

Modification Of Ct Quality Assurance Phantom For Pet/Ct Alignment And Pet Resolution, Prashanth K. Nookala Jan 2005

Modification Of Ct Quality Assurance Phantom For Pet/Ct Alignment And Pet Resolution, Prashanth K. Nookala

LSU Master's Theses

Radiotherapy treatment planning utilizing PET and CT is rapidly gaining acceptance in oncology. A limiting factor of the dual modality is the PET/CT alignment. A small error in PET/CT alignment may result in giving large doses of radiation to healthy tissues as a result of poor treatment planning. For this purpose, regular quality assurance testing of PET/CT must be performed. Separate QA procedures and phantoms have been developed for the two different modalities. In particular, many existing phantoms cannot be used for both modalities, which is a requirement for evaluating PET/CT alignment. Our goal is to evaluate several existing phantom …

Skepticism About Contextualism, William Galloway Osborne Iii Jan 2005

Skepticism About Contextualism, William Galloway Osborne Iii

LSU Master's Theses

Contextualism is the epistemological thesis that holds context to significantly affect the truth value of claims such as “S knows that p.” A shift in context can lead to a shift in the standards by which we evaluate propositional knowledge claims, and thus a shift in the truth values of these claims: a statement “S knows that p” may be true when evaluated in one context while simultaneously false when evaluated in another context. A contextualist says it is by playing on these shifting standards that the skeptic manages to destroy knowledge with her skeptical arguments. Once this is understood, …
