Application Of Surface-Ocean Remote-Sensing To The Characterisation Of Biogeographic Patterns Of Benthic Fauna In A Temperate Shelf Sea, Kirsten Alexandra Richardson Jan 2007

Application Of Surface-Ocean Remote-Sensing To The Characterisation Of Biogeographic Patterns Of Benthic Fauna In A Temperate Shelf Sea, Kirsten Alexandra Richardson

School of Biological and Marine Sciences Theses

Ecosystem scale, adaptive management of the marine environment, emphasised by the Convention on Biological Diversity, requires a clear understanding of the spatial and temporal dynamics of the system in question. Classical species-based biogeography alone is not sufficient to describe those dynamics at the appropriate scale for whole ecosystem management. A novel, multidisciplinary, complex systems approach has been developed for characterising the biogeographic distribution of benthic fauna in a temperate shelf sea system through application of remote sensing to the principles of benthic-pelagic coupling. A six year time series of satellite remote sensing data (AVHRR SST and SeaWiFS Chl-α, LwN(555, 670)) …

Effects Of Hyperbaric Oxygen On Oxidative Stress, Angiogenesis Factors And Endothelial Cell Injury, Jianfeng Yuan Jan 2007

Effects Of Hyperbaric Oxygen On Oxidative Stress, Angiogenesis Factors And Endothelial Cell Injury, Jianfeng Yuan

School of Biological and Marine Sciences Theses

Hyperbaric oxygen (HBO) therapy is the administration of 100% oxygen at more than one atmosphere. It greatly improves tissue oxygenation and facilitates mechanisms of wound healing, which in turn benefits some patients with chronic wounds. A prominent fact in therapeutic HBO is the acceleration of neoangiogenesis during granulation tissue formation. Angiogenesis is a highly orchestrated event, a diverse range of cells and angiogenesis factors are involved in the process. The formation of reactive oxidative species (ROS) during HBO has been controversially considered as signalling regulator for angiogenic factors, as well as harmful originator for oxidative stress-induced cyto- and geno-toxicity in …

An Evaluation Of Multivariate Statistical Techniques For The Analysis Of Yield From Barley (Hordeum Vulgare L.) Breeding Trials Data, Ahmed Abdullah Jan 2007

An Evaluation Of Multivariate Statistical Techniques For The Analysis Of Yield From Barley (Hordeum Vulgare L.) Breeding Trials Data, Ahmed Abdullah

School of Biological and Marine Sciences Theses

This project involved two locations (Breda and Tel Hadya) over two seasons (1993 and 1994). Yield was found to have been affected by many factors including environment, genotype and morphological characters. A genotype-environment interaction (GEl) was also discovered. To investigate the influence of morphological characters on yield parameters, multivariate statistical techniques (canonical analysis, factor analysis and multiple regression analysis (linear and exponential)) were used. Multivariate statistical techniques were applied to three hybrids (Hybrid 1, 2 and 3) in replicated field plots at two locations (Breda and Tel Hadya) in two seasons. Canonical analysis and factor analysis revealed a significant relationship …

Motivational Influences On Compliance With And Consequences Of Instructions To Suppress Stereotypes, Na Wyer Jan 2007

Motivational Influences On Compliance With And Consequences Of Instructions To Suppress Stereotypes, Na Wyer

School of Psychology

Two experiments investigated differences in compliance with instructions to suppress stereotypes as a function of prejudice-related motivations. In Experiment 1, only participants identified as high in motivation to control prejudice [Dunton, B. C., & Fazio, R. H. (1997). An individual difference measure of motivation to control prejudiced reactions. Personality and Social Psychology Bulletin, 23, 316–326] complied with suppression instructions. These participants experienced post-suppression rebound effects, but only if they were also high in prejudice. In Experiment 2, only participants identified as high in external motivation to respond without prejudice [Plant, E. A., & Devine, P. G. (1998). Internal and external …

Ambiguous Women: Debates Within American Evangelical Feminism, A Syska Jan 2007

Ambiguous Women: Debates Within American Evangelical Feminism, A Syska

School of Law, Humanities and Social Sciences

This article is an analysis of major debates within American evangelical feminism since its emergence in early 1970s. It examines ways in which American evangelical feminists negotiate their identity in the daily struggle between the mundane and the sacred, home setting and church practice, and their private and public lives. Through presentation of personal stories and lived experiences it argues that evangelical feminists' ambiguity is a significant and powerful force that not only forges distinctive self-awareness among evangelical feminists, but also shapes diverse understandings of evangelical feminism and shifts the boundaries of both evangelicalism and feminism in America.

Species Interactions During Succession In Rockpools: Role Of Herbivores And Physical Factors, Laure Marie-Louise Jeanne Noel Jan 2007

Species Interactions During Succession In Rockpools: Role Of Herbivores And Physical Factors, Laure Marie-Louise Jeanne Noel

School of Biological and Marine Sciences Theses

Positive interactions are increasingly recognised to be important as community structure processes. Bertness and Callaway's model predicts positive interactions to be important under high consumer pressure or high environmental stress. Associational defences between organisms, when palatable algae take advantage of living with less palatable ones, will be the dominant structuring forces under high consumer pressure and low physical stress. Habitat ameliorations become more important under harsh physical conditions and low consumer pressure. This model was tested at Wembury Bay, Devon, Southwest England, using rockpools and emergent rock habitats distributed over the vertical height of the shore to generate gradients of …

Anti-Predator Behaviour In The Freshwater Gastropod Lymnaea Stagnalis, Sarah Joanne Dalesman Jan 2007

Anti-Predator Behaviour In The Freshwater Gastropod Lymnaea Stagnalis, Sarah Joanne Dalesman

School of Biological and Marine Sciences Theses

The freshwater gastropod Lymnaea stagnalis was used as a model organism to investigate the mechanisms employed by prey species to fine-tune anti-predator behaviour to match their environment. Lymnaea stagnalis was found to exhibit both genetic adaptation of innate responses and also induced responses to predator cues. Snails were also capable of responding to predation cues via associative learning dependent on recent experience. Constitutive responses were found to differ between populations depending on the predator regime that the population experienced in the wild. Artificial selection produced in only two generations a difference in the magnitude of response between high and low …

Ecological Impact Of The Carcinus Maenas (L.) Fishery 'Crab-Tiling' On Estuarine Fauna, Emma Sheehan Jan 2007

Ecological Impact Of The Carcinus Maenas (L.) Fishery 'Crab-Tiling' On Estuarine Fauna, Emma Sheehan

School of Biological and Marine Sciences Theses

The ecological effects of the green shore crab Carcinus maenas (L.) fishery was investigated in estuaries on the south west coast of the UK. The fishery known as 'crab-tiling' involves 'crab-tilers' laying artificial refugia such as car tyres, guttering or roof tiles, intertidally in estuaries. 'Crab-tiles' are specifically laid on mudflats and sandflats to attract moutling crabs seeking refuge, these crabs are then collected to use or sell as bait for recreational angling. Many estuaries that are crab-tiled are subject to a range of International, European and National legislation as they are of great conservation importance. For example, they provide …

Bend It Like Beckham: Embodying The Motor Skills Of Famous Athletes, P Bach, Sp Tipper Dec 2006

Bend It Like Beckham: Embodying The Motor Skills Of Famous Athletes, P Bach, Sp Tipper

School of Psychology

Observing an action activates the same representations as does the actual performance of the action. Here we show for the first time that the action system can also be activated in the complete absence of action perception. When the participants had to identify the faces of famous athletes, the responses were influenced by their similarity to the motor skills of the athletes. Thus, the motor skills of the viewed athletes were retrieved automatically during person identification and had a direct influence on the action system of the observer. However, our results also indicated that motor behaviours that are implicit characteristics …

Mechanisms Of Larval Transport: Vertical Distribution Of Bivalve Larvae Varies With Tidal Conditions, Am Knights, Tp Crowe, G Burnell Nov 2006

Mechanisms Of Larval Transport: Vertical Distribution Of Bivalve Larvae Varies With Tidal Conditions, Am Knights, Tp Crowe, G Burnell

School of Biological and Marine Sciences

Larval transport is a key process in the life-history and population dynamics of many marine species. It is strongly influenced by ocean currents, but the influence of behavioural traits of larvae (e.g. vertical migration) on their advective dispersal is poorly understood. In the absence of field data, predictions of population connectivity are often based on hydrodynamic models and assume that larvae behave as passive particles. Variations in the vertical distribution of early and late stage larvae of Mytilus spp. were investigated in a field study in the Irish Sea, collecting discrete water samples by Niskin sampler at a range of …

Inclusion And Equity In Hpe Policy And Practice: An Evaluation Of School Responses Within Three Brisbane Catholic Education (Bce) Primary Schools., Tj Lynch Oct 2006

Inclusion And Equity In Hpe Policy And Practice: An Evaluation Of School Responses Within Three Brisbane Catholic Education (Bce) Primary Schools., Tj Lynch

Plymouth Institute of Education

The 1999 Queensland P-10 Health and Physical Education syllabus adopted a socio-cultural approach to learning, underpinned by social justice principles which include diversity, equity and supportive environments. This approach has afforded HPE even greater relevance in Catholic schools. Successful implementation of inclusion and equity within the syllabus requires teachers to have an understanding of various pedagogies and an awareness of when to choose the most appropriate. This research has been designed within a constructionist paradigm. An interpretivist study was conducted employing symbolic interactionism. This qualitative, interpretive study is most appropriate as meanings were constructed. The case study methodology was chosen …

Up-Regulation Of The Notch Ligand Delta-Like 4 Inhibits Vegf-Induced Endothelial Cell Function, Ck Williams, J-L Li, M Murga, Al Harris, G Tosato Feb 2006

Up-Regulation Of The Notch Ligand Delta-Like 4 Inhibits Vegf-Induced Endothelial Cell Function, Ck Williams, J-L Li, M Murga, Al Harris, G Tosato

School of Biomedical Sciences

Delta-like 4 (Dll4), a membrane-bound ligand for Notch1 and Notch4, is selectively expressed in the developing endothelium and in some tumor endothelium, and it is induced by vascular endothelial growth factor (VEGF)-A and hypoxia. Gene targeting studies have shown that Dll4 is required for normal embryonic vascular remodeling, but the mechanisms underlying Dll4 regulatory functions are currently not defined. In this study, we generated primary human endothelial cells that overexpress Dll4 protein to study Dll4 function and mechanism of action. Human umbilical vein endothelial cells retrovirally transduced with Dll4 displayed reduced proliferative and migratory responses selectively to VEGF-A. Expression of …

Active Security Vulnerability Notification And Resolution, Abdulaziz Ibrahim Alayed Jan 2006

Active Security Vulnerability Notification And Resolution, Abdulaziz Ibrahim Alayed

School of Engineering, Computing and Mathematics Theses

The early version of the Internet was designed for connectivity only, without the consideration of security, and the Internet is consequently an open structure. Networked systems are vulnerable for a number of reasons; design error, implementation, and management. A vulnerability is a hole or weak point that can be exploited to compromise the security of the system. Operating systems and applications are often vulnerable because of design errors. Software vendors release patches for discovered vulnerabilities, and rely upon system administrators to accept and install patches on their systems. Many system administrators fail to install patches on time, and consequently leave …
