Factors Associated With Stiff Knee Gait In Cerebral Palsy, Eleanor Frances Compton Jan 2015

Factors Associated With Stiff Knee Gait In Cerebral Palsy, Eleanor Frances Compton

Other Faculty of Health Theses

Stiff knee gait (SKG) is one of a few classified walking patterns which people with cerebral palsy (pwCP) can present with. The characteristic for SKG is delayed and/or reduced peak knee flexion during swing phase, which can reduce walking ability and result in functional restrictions. Through the use of both clinical and laboratory based measures this cross-sectional study aimed to identify the factors associated with SKG, suggest possible treatment options and propose potential directions for future research. The impact of five variables on knee flexion amplitude during the swing phase of gait was assessed. Data was gathered from a group …

Brain Inspired Approach To Computational Face Recognition, Joao Paulo Da Silva Gomes Jan 2015

Brain Inspired Approach To Computational Face Recognition, Joao Paulo Da Silva Gomes

Other Faculty of Science and Engineering Theses

Face recognition that is invariant to pose and illumination is a problem solved effortlessly by the human brain, but the computational details that underlie such efficient recognition are still far from clear. This thesis draws on research from psychology and neuroscience about face and object recognition and the visual system in order to develop a novel computational method for face detection, feature selection and representation, and memory structure for recall. A biologically plausible framework for developing a face recognition system will be presented. This framework can be divided into four parts: 1) A face detection system. This is an improved …

The Influence Of Engineering Design Considerations On Species Recruitment And Succession On Coastal Defence Structures, Juliette Elizabeth Jackson Jan 2015

The Influence Of Engineering Design Considerations On Species Recruitment And Succession On Coastal Defence Structures, Juliette Elizabeth Jackson

Other Faculty of Science and Engineering Theses

Engineering design considerations of artificial coastal structures were tested to resemble as far as possible the nearest natural equivalent habitat, ecologically valuable rocky shores, as a potential management option. Coastal areas around the world attract urbanisation but these transitional areas between sea and land are inherently vulnerable to risk of flooding and erosion. Thus hard structures are often built in sensitive coastal environments to defend assets such as property and infrastructure (roads, railways, ports) against rising and stormy seas. The design, construction and maintenance of hard defences should wherever possible incorporate ecological considerations to enhance biodiversity, including maintaining or restoring …

Deoxynivalenol: Toxicological Profile And Potential For Reducing Cereal Grain Contamination Using Bacterial Additives In Fermented Animal Feed., William Vevers Jan 2015

Deoxynivalenol: Toxicological Profile And Potential For Reducing Cereal Grain Contamination Using Bacterial Additives In Fermented Animal Feed., William Vevers

Other Faculty of Science and Engineering Theses

Deoxynivalenol (DON) contamination of grain destined for animal feeds is a major toxicological risk to monogastrics and is suspected of restricting productivity in ruminants. Whereas bacterial additives have been developed that can detoxify DON in the rumen and lower intestine, there are currently no commercial inoculants able to perform this task in crimped grain (CG) silage, a regionally important method of moist grain preservation based on homo- and heterofermentative lactic acid bacteria or chemical additives. Determining whether this ensiling process alongside the action of detoxifying bacteria has the potential to remove DON in CG prior to ingestion, was explored in …

The Effect Of Dynamic Mobilisation Exercises On The Equine Multifidus Muscle And Thoracic Profile, Gillian Tabor Jan 2015

The Effect Of Dynamic Mobilisation Exercises On The Equine Multifidus Muscle And Thoracic Profile, Gillian Tabor

Other Faculty of Science and Engineering Theses

Introduction: A relationship between spinal musculature and back pathology has been established in human and equine studies. Exercises to increase Multifidus cross sectional area (CSA) have been shown to reduce the amount and reoccurrence of back pain in humans. Similarly dynamic mobilisation exercises (DME) have led to an increase Multifidus CSA in horses on box rest. The effect of DME on the Multifidus muscle of thoroughbred racehorses in training was investigated and two measurement methods, that can be used to evaluate the outcome of a treatment or exercise programme on Multifidus, were compared. Methods: Ultrasound imaging was used to measure …

Optimisation Of Rebreeding Strategy In Uk Holstein Dairy Cattle- A Multifactorial Study, Richard Michael Miller Jan 2015

Optimisation Of Rebreeding Strategy In Uk Holstein Dairy Cattle- A Multifactorial Study, Richard Michael Miller

Other Faculty of Science and Engineering Theses

Dairy production in the UK has undergone a period of sustained increase both in number of cows held in each unit and yields per cow. Whilst much of this yield increase can be attributed to nutritional science, the production capacity of individual animals has also contributed significantly through both higher peak yields and greater persistency of production throughout lactation. This additional production has not come without cost which has manifested itself as a general decrease in reproductive performance. Although the associated lengthening of the calving interval has led to an increase in herd average days in milk, the question arises …

Art In The Public Realm And The Politics Of Rural Leisure: Access And Environment, Alex Murdin Jan 2015

Art In The Public Realm And The Politics Of Rural Leisure: Access And Environment, Alex Murdin

Other Faculty of Arts, Humanities and Business Theses

Exploring both political aesthetics and the politics of aesthetics to outline an environmental ruralism for art in public spaces, this practice lead research project postulates a “complemental practice”, outlining its methodology and contexts for operation, the rural, spaces of leisure and the public realm. It is a response to threats to spatial and environmental commons from heritage, place-making and nostalgia, psychological inhibition such as a sense of global contingency and widespread economic exploitation. Responses by artists to this situation can be characterised as a binary of dialogism (Kester, 2004) and relational antagonism (Bishop, 2004), i.e. consensual/collaborative or antagonistic/autonomous practices.

The Legal Regimes Governing Marine Renewable Energy In England And Wales, Victoria Jane Hamlyn Jan 2015

The Legal Regimes Governing Marine Renewable Energy In England And Wales, Victoria Jane Hamlyn

Other Faculty of Arts, Humanities and Business Theses

This thesis involves an examination of the main international, regional and national legal regimes regulating marine renewable energy in England and Wales. Deriving from a complex patchwork of law and policy, developments have ensued in the absence of a distinct governing ‘legal regime’ and within a number of competing paradigms. This original synthesis attempts to identify lacunae, conflicts and connections within and between the span of legal genres that MRE evokes. Against a backdrop of climate change mitigation, the key findings show that despite the presence of political will for offshore renewable energies, MRE development faces a number of legal …

Every Frame Counts: Creative Practice And Gender In Direct Animation, Kayla Parker Jan 2015

Every Frame Counts: Creative Practice And Gender In Direct Animation, Kayla Parker

Other Faculty of Arts, Humanities and Business Theses

This thesis interrogates the ways in which the body-centred practices of women film artists embrace the materiality of direct animation in order to foreground gendered, subjective positions. Through the researcher's own creative practice, it investigates how this mode of film-making, in which the artist works through physical engagement with the film materials and the material processes of film-making, might be understood as feminine and/or feminist. Direct animation foregrounds touch as the primary sense. Its practices are process-based and highly experimental, because images are made through the agency of the body operating within restrictive parameters, making results difficult to predict or …

An Ontology Of Space: Methodological Recursiveness And The Diagram, Rita Cachao Jan 2015

An Ontology Of Space: Methodological Recursiveness And The Diagram, Rita Cachao

Other Faculty of Arts, Humanities and Business Theses

Current debates on space reveal a dichotomy between two apparently conflicting understandings of space: on the one hand, space is understood as a physical, tangible entity that has an impact on how we perceive, feel and emotionally inhabit the world, and on the other hand, space is conceived as an abstract entity, suggesting that space has no active role (a productivity) within everyday life, being solely a conceptual product of intellectual reasoning. As a result, the commonly used word: ‘space’, will be discussed as an ontologically paradoxical, ambiguous and elusive concept; a concept that cannot be captured within a single …

Polyphibianism: Evolving Transdisciplinarity Into An Imaginary Organism Of Living Knowledge, Ziva Ljubec Jan 2015

Polyphibianism: Evolving Transdisciplinarity Into An Imaginary Organism Of Living Knowledge, Ziva Ljubec

Other Faculty of Arts, Humanities and Business Theses

Transdisciplinarity emerged from the urge to grasp the elusive knowledge in the most fertile zone in between and beyond disciplines that escapes even the most elaborate interdisciplinary operations. While interdisciplinary protocol enables experts to operate within foreign disciplines, in the extreme case as diverse as art and science (by inviting artists into scientific departments and vice versa), the production of knowledge remains confined to particular domains. To transcend these confinements and access the knowledge that evades institutionalisation Basarab Nicolescu’s Manifesto of Transdisciplinarity sets up conditions for an open structure to be grown outside the current compartmentalisation into a living knowledge. …

The Application Of Ocean Front Metrics For Understanding Habitat Selection By Marine Predators, Kylie Lisa Scales Jan 2015

The Application Of Ocean Front Metrics For Understanding Habitat Selection By Marine Predators, Kylie Lisa Scales

Other Faculty of Science and Engineering Theses

Marine predators such as seabirds, cetaceans, turtles, pinnipeds, sharks and large teleost fish are essential components of healthy, biologically diverse marine ecosystems. However, intense anthropogenic pressure on the global ocean is causing rapid and widespread change, and many predator populations are in decline. Conservation solutions are urgently required, yet only recently have we begun to comprehend how these animals interact with the vast and dynamic oceans that they inhabit. A better understanding of the mechanisms that underlie habitat selection at sea is critical to our knowledge of marine ecosystem functioning, and to ecologically-sensitive marine spatial planning. The collection of studies …

Investigation Of Microplastic Debris In Marine Surface Waters Using Different Sampling Methods, Saeed Seyed Sadri Jan 2015

Investigation Of Microplastic Debris In Marine Surface Waters Using Different Sampling Methods, Saeed Seyed Sadri

Other Faculty of Science and Engineering Theses

‘Microplastics’ are pieces of plastic debris <5mm in diameter. They are introduced into the marine environment directly for example via release of small pieces of plastics used as abrasives and indirectly through the fragmentation of larger items. The European Marine Strategy Framework Directive 2008/56/EC (MSFD) regards microplastics as an emerging issue of concern and calls for more data on the quantity, distribution and composition of this debris. This thesis examines the amount, composition and distribution of buoyant microplastic debris in marine waters using different sampling devices and methodologies. To investigate the spatial distribution, abundance and composition of microplastic debris between nearshore and offshore marine subsurface waters a subset of samples from the Continuous Plankton Recorder (CPR) survey were examined. Abundance was generally higher in nearshore coastal waters than the offshore oceanic samples, with the highest mean concentrations observed in the UK’s coastal waters of the northeast Atlantic and the southern North Sea. To validate the accuracy of the presence/absence of microplastic debris reported in the Continuous Plankton Recorder (CPR) samples by analysts at the Sir Alister Hardy Foundation for Ocean Science (SAHFOS) a subset of data was formally analysed using Fourier Transform Infrared (FTIR) spectroscopy. This analysis indicated a good level of accuracy (~66%) in the ability of the SAHFOS’ analysts to detect visually microplastic fragments during their normal processing of plankton samples. To compare quantity and composition of buoyant microplastic debris collected by two different approaches (CPR vs. Manta net) samples were collected from a similar body of coastal waters. The results showed significantly higher abundance of microplastic in samples collected by the manta net per unit of distance but no significant difference once the results were standardised per cubic volume of water. To assess the susceptibility of each method to ‘procedural contamination’, repetitive controlled tests were conducted to quantify the amount and composition of contaminants before, during and after the sampling programme. In both methods the highest number of contaminants was found on the net and prior to the deployment to sea. The semi synthetic Rayon fibres were the most abundant type of contaminants in both cases. To compare the abundance and composition of buoyant plastic debris in estuarine waters according to daily and lunar tidal cycles a mensurative experiment was conducted in a macrotidal Estuary. Microplastics comprised 82% of the debris and there was a significant difference in size frequency distribution between the spring and neap tides with more fragments of larger size observed during spring tides. In conclusion, this study shows further evidence of the spatial heterogeneity of microplastic debris distribution in marine waters and therefore also highlights the need for more comparable data from different marine habitats using standardised methodologies.

Distributions Of Glycine Betaine And The Methylamines In Coastal Waters: Analytical Developments And A Seasonal Study, Charlotte Cree Jan 2015

Distributions Of Glycine Betaine And The Methylamines In Coastal Waters: Analytical Developments And A Seasonal Study, Charlotte Cree

Other Faculty of Science and Engineering Theses

A novel technique comprising solid phase microextraction and gas chromatography has been developed to analyse the three methylamines (monomethylamine, dimethylamine and trimethylamine) at the concentrations expected in seawater. The volatility of the methylamines was exploited and allowed the headspace pre-concentration and gas chromatographic separation of the analytes. This method achieved limits of detection of 0.43 nmol dm-3, 2.50 nmol dm-3 and 0.37 nmol dm-3 for monomethylamine, dimethylamine and trimethylamine, respectively, which are lower than any previously reported for seawater. This technique was applied to natural samples collected from the Western English Channel (WEC) and the methylamines were successfully quantified. A …

The Effects Of Lateralisation On Detour Based Problem Solving In Horses (Equus Caballus), Hannah Savin Jan 2015

The Effects Of Lateralisation On Detour Based Problem Solving In Horses (Equus Caballus), Hannah Savin

Other Faculty of Science and Engineering Theses

Potential impact of motor laterality on equine performance has resulted in research into this aspect of equine behaviour. Many studies demonstrate that equids exhibit a preference for one side over the other but there is little evidence for directional biases. In modern day equestrian practices, equids are frequently required to manoeuvre around objects and laterality preferences may hinder or aid in this movement. The aim of this study was to investigate if horses consistently show a directional preference during a detour task. Twenty three horses of various breeds, ages and sexes were required to obtain a goal, a piece of …

Reanimating The Wound: Dermatilliomanic Practice And The First World War, Camilla Nock

Other Faculty of Arts, Humanities and Business Theses

This research project uses an exploratory painting practice to examine a melancholic shadow cast by the First World War. The mode of inquiry is predicated upon the persistence of the past in the present, and upon a personal need to purge a persisting familial grief. To inform this stance there is systematic engagement with cathartic and redemptive artworks of the twentieth century, and with the poetry of the First World War. Developments of process and emotional register are specifically prompted by the writings of William Morris, Edmund Blunden, and Ivor Gurney, and reflections on practice are sub-divided accordingly. Wilfred Owen’s …

Ecological Understanding Through Transdisciplinary Art And Participatory Biology, Brandon Ballengée Jan 2015

Ecological Understanding Through Transdisciplinary Art And Participatory Biology, Brandon Ballengée

Other Faculty of Arts, Humanities and Business Theses

In this study evidence is presented that suggests transdisciplinary art practices and participatory biology programs may successfully increase public understanding of ecological phenomenon. As today’s environmental issues are often complex and large-scale, finding effective strategies that encourage public awareness and stewardship are paramount for long-term conservation of species and ecosystems. Although artists and biologists tend to stay confined to their professional boundaries, and their discourses largely remain inaccessible to larger audiences, arguments here are presented for a combined approach, which may disseminate knowledge about ecology to non-specialists through novel art-science participatory research and exhibitions. Moreover, historically several scientists utilized varied …

Evidence Of Things Not Seen: A Semi-Automated Descriptive Phrase And Frame Analysis Of Texts About The Herbicide Agent Orange, Sarah Beth Hopton

USF Tampa Graduate Theses and Dissertations

From 1961 to 1971 the United States and the Republic of South Vietnam used chemicals to defoliate the coastal and upload forest areas of Viet Nam. The most notorious of these chemicals was named Agent Orange, a weaponized herbicide made up of two chemicals that, when combined, produced a toxic byproduct called TCDD-dioxin. Studied suggest that TCDD-dioxin causes significant human health problems in exposed American and Vietnamese veterans, and possibly their children (Agency, U.S. Environmental Protection, 2011). In the years since the end of the Vietnam War, volumes of discourse about Agent Orange has been generated, much of which is …
