The Dynamics Of Suspended Particles In A Seasonally Stratified Coastal Sea, Jaimie Cross

Other Faculty of Science and Engineering Theses

A comprehensive investigation into the relationship between physical forcing and sus- pended particles in the shallow shelf region of the Western English Channel has been conducted, in order to evaluate the temporal dynamics of suspended particle populations. Measurements were taken across tidal cycles and seasons at station L4, part of the Western Channel Observatory (WCO), using the combination of a free-fall microstructure profiler and holographic imaging. Confirmation that L4 is weakly stratified is given, and that the formation of the seasonal thermocline is substantially altered by the spring-neap cy- cle. Stratification is variable and prone to periodic and partial erosion …

Other Faculty of Arts, Humanities and Business Theses

This dissertation explores the use of irony in networked wearable technology art as a strategy to emphasise the complexity of conjunction between techno-organic human and the techno-organic world. The research addresses the relationship between technologically enhanced human and networked hybrid environment, and speculates on the impact of technological enhancements to the subjective construction of Umwelt through ironic interventions. The project employs both artistic practice and critical theory. The practice-based part of the dissertation is comprised of three wearable technology artworks produced during the study. These concrete artefacts employ irony as a means to expose the techno-organic relationship between humans and …

An Artificial Intelligence Approach To Concatenative Sound Synthesis, Noris Mohd Norowi

Other Faculty of Arts, Humanities and Business Theses

Technological advancement such as the increase in processing power, hard disk capacity and network bandwidth has opened up many exciting new techniques to synthesise sounds, one of which is Concatenative Sound Synthesis (CSS). CSS uses data-driven method to synthesise new sounds from a large corpus of small sound snippets. This technique closely resembles the art of mosaicing, where small tiles are arranged together to create a larger image. A ‘target’ sound is often specified by users so that segments in the database that match those of the target sound can be identified and then concatenated together to generate the output …

Diffracting Representation: Towards A Situated Aesthetics Of Technospaces, Federica Timeto

Other Faculty of Arts, Humanities and Business Theses

My research for this thesis focusses on the concepts of representation and space in order to demonstrate their theoretical and practical co-implications. Discussing various theorists of space in the first part and analyzing a number of artists and artworks as case studies in the second part, I elaborate a critique of the representational imaginary in order to articulate an alternative notion of representation by means of which a relational, qualitative and performative spatiality can emerge. I specifically focus on technospaces, which I consider a privileged field for observing the intersections of representation and spatiality; it is a field in which …

The Composer Isn't There: A Personal Exploration Of Place In Fixed Media Composition, Hilary Mullaney

Other Faculty of Arts, Humanities and Business Theses

This practice-based research is concerned with a collection of fixed media compositions written between 2005 and 2012 with accompanying contextual writing. The primary focus of this research was to produce sound works, but the concept of place has played a significant role throughout both the compositional process and in the reflection of each composition. This research explores how place is ‘heard and felt’ (Feld, 2005) in a composition and how recollected memory impacts on the compositional process. Artistic decisions made with regard to creating the compositions reflect my personal place and associations with these sound materials at a given time …

A Critical Practice-Based Exploration Of Interactive Panoramas' Role In Helping To Preserve Cultural Memory, Karol Kwiatek

Other Faculty of Arts, Humanities and Business Theses

The rapid development of digital communication technologies in the 20th and 21st centuries has affected the way researchers look at ways memory – especially cultural memory – can be preserved and enhanced. State-of-the-art communication technologies such as the Internet or immersive environments support participation and interaction and transform memory into ‘prosthetic’ experience, where digital technologies could enable 'implantation' of events that have not actually been experienced. While there is a wealth of research on the preservation of public memory and cultural heritage sites using digital media, more can be explored on how these media can contribute to the cultivation of …

Lexical/Semantic Organisation In Bilingual And Monolingual Infants, Rafalla Farag

Other Faculty of Science and Engineering Theses

Abstract Previous studies show that bilingual infants are slower in developing phonology and tend to experience some difficulties in acquiring some grammatical rules. Furthermore, as compared to their monolingual peers, bilingual infants tend to have less vocabulary. This thesis set out to explore how bilingual infants organise the lexical information in their two languages. Specifically, we examined the lexical-semantic relationships between words within and across languages using a word-to-word priming paradigm. The thesis sought also to uncover any relationship between semantic priming effects and the size of vocabulary. Vocabulary measures such as the BPVS II, the SETK, and the Oxford …

Allelopathic Potential Of The Invasive Alien Himalayan Balsam (Impatiens Glandulifera Royle), Owen Peter Smith

Other Faculty of Science and Engineering Theses

Investigations were carried out into the allelopathic potential of the invasive alien annual Himalayan Balsam (Impatiens glandulifera Royle) using a series of bioassays, including ones developed or adapted for this study. They were evaluated for their suitability to detect three of the four main modes of allelochemical release, namely leaching, exudation and decomposition. Assays which involved the measurement of lettuce radicles and hypocotyls gave reliable results and allowed a range of different Impatiens material, both living and dead, to be assessed and ranked according to the allelopathic effects demonstrated. Attempts were made to isolate resource competition from allelopathy using separately …

Histopathological Effects Of Metal And Metalic Nanoparticles On The Body Systems Of Rainbow Trout (Oncorhynchus Mykiss), Genan Adnan Al-Bairuty

Other Faculty of Science and Engineering Theses

Histopathology studies of metal nanoparticles (NPs) compared to traditional forms of metal in fish are scarce. Additionally, it is unclear whether metal nanoparticles cause greater or different pathologies compared to other forms of metal. The current study aimed to assess the pathological effects of Cu-NPs and TiO2 NPs on rainbow trout via various routes of exposure and, where appropriate, to compare them to either the equivalent dissolved metal salts or bulk powder forms. The first experiment showed that waterborne exposure to Cu-NPs and CuSO4 caused similar types of organ pathologies and alteration in the spleen content, however there were some …

Effects Of Short Term Stretching On Ankle Stiffness And Range Of Motion In People With Multiple Sclerosis, Jodielin Ofori

School of Health Professions Theses

Hypertonia is seen in 85% of people with Multiple Sclerosis (pwMS) resulting in disability and functional restrictions. Hypertonia can be caused by increases in passive stiffness and enhanced stretch reflexes (spasticity) and is frequently managed clinically using passive stretches. However, the optimal parameters of stretching such as the applied torque and stretch duration remain unclear. During commonly prescribed ankle plantarflexor stretches pwMS produced higher torques when standing in a weight bearing position compared to stretches applied using the upper limbs. Stretches could be held for 120 seconds on average and stretch duration was mainly limited by fatigue. People with higher …

Bodies, Emotions And Tourism: A Study Of Costa Cruises Commercials, Mariangela Albano, Gaetano Sabato

Journal of Tourism Consumption and Practice

Nowadays, tourism industry proposes different opportunities to live a vacation where the body is the main interest and the central focus of experience. Each form of tourism shows a particular universe of representation of the body and a corresponding emotional language. In this context, where bodies and spaces are associated and reciprocally constructed as symbolic languages for the benefit of the tourist’s extraordinary experience, cruise tourism is an interesting case in point to analyze above all because on cruises, people use the space of the ship in different ways and, at the same time, following general corporeal and spatial schemes. …

The Use Of Silver Nanoparticles As An Antifungal Coating On Silicone Facial Prosthesis, Zhala Meran

Other Faculty of Science and Engineering Theses

Abstract Introduction Maxillofacial prostheses are used to substitute lost facial parts, but give variable clinical results due to complications such as contamination and infection. Candida albicans infection remains a significant problem for facial prostheses made of silicone, as the organism causes degradation of the material and infection of the surrounding tissue. This study investigated the antifungal properties of silver nanoparticles (Ag NPs) as a coating on silicone facial prostheses to eliminate infection. Methods The experimental approach used fibroblast cell cultures to test the biocompatibility of Ag NPs and to demonstrate the safety of Ag NPs compared to AgNO3 at concentrations …

Mood, Emotive Content, And Reasoning, Daniel Zahra

Other Faculty of Science and Engineering Theses

Mood, Emotive Content, and Reasoning - Daniel Zahra Theories of how individuals reason, and how they experience emotion abound in the psychological literature; yet, despite the common lay-theories of how emotions might affect a person’s reasoning, very little empirical work has been conducted on this relationship. The current thesis addresses this knowledge-gap by first distilling from the literature two classes of emotion theory; Information, and Load; and then systematically testing the explanatory power of these theories. A dual-process framework is employed in order to define low (Type One) and high effort (Type Two) strategies. Information theories predict that negative emotion …

Temporal and vertical IP25 concentrations were measured in sea ice from a second location in the Canadian Arctic, Resolute Bay, Nunavut. Sea ice samples were collected as part of the Arctic ICE project in collaboration with scientists of the University of Manitoba from April to June 2011. Comparisons were made between other established lipid biomarkers of diatom origin and general organic production, along with previously established temporal and vertical distributions in sea ice collected from the Amundsen Gulf, …

The Characterisation Of The Freezing Damage Response During Flowering In European And Middle Eastern Wheat Cultivars (Triticum Aestivum L), Mohammed Hamdan Edan Al-Issawi

Other Faculty of Science and Engineering Theses

Wheat (Triticum aestivum L.) is occasionally exposed to low temperature during flowering and huge economic losses can occur especially in some key production countries such as Australia. Although it is generally predicted that there will be a rise in global temperature there are still predicted to be risks associated with low temperature for temperate crops. Post head emergence frost damage remains a major constraint to increasing wheat production. Five Iraqi varieties (Abu-Ghariab, Fatah, Sham6, IPA95 and IPA99) were screened for their frost hardiness (LT50). Abu-Ghariab was chosen for further investigations along with the European cv. Claire because the acclimated frost …

Molecular Characterisation Of Clinical And Environmental Isolates Of Vibrio Parahaemolyticus, Hadaf Mahdi Kadhim

Other Faculty of Science and Engineering Theses

The halophilic bacterium Vibrio parahaemolyticus is widely distributed as a natural inhabitant of marine and estuarine environments. Some strains cause gastroenteritis in humans. Clinical isolates are thought to possess virulence factors that are absent from the majority of environmental isolates. Studies were undertaken to differentiate clinical (virulent) and environmental (mainly avirulent) forms of Vibrio parahaemolyticus. Initially, identification and confirmation of a total of 55 V. parahaemolyticus isolates (23 clinical and 32 environmental) was carried out by using selective media, biochemical and nutritional tests. Identity was confirmed by specific polymerase chain reaction (PCR) targeting the toxR gene. In an attempt to …

Visual Images As A Motivational Bridge To Pro-Environmental Behaviour: A Cognitive Approach, Christine Boomsma

Other Faculty of Science and Engineering Theses

Communicating climate change and other long-term environmental issues to the wider public is a challenging process involving many barriers to action. Visualisations have the ability to overcome these barriers. Furthermore, the benefits of visual images over verbal information have been supported. However, there is a lack of research on how visual images can motivate behaviour. Based on Elaborated Intrusion theory, it is proposed that visual images can be internalised as mental images which can act as a ‘motivational bridge’ for pro-environmental behaviour. Six studies exposed participants to visual pro-environmental messages. Throughout all studies images were internalised as mental images, associated …

The Effect Of Hyperbaric Oxygen Therapy On Osteoclast And Osteoblast Function, Hadil Al-Hadi

Other Faculty of Science and Engineering Theses

Bone remodelling, the process by which the skeleton adapts to environmental changes, is dependent on the actions of osteoclasts that resorb bone and osteoblasts which make new bone matrix. Aberrant remodelling underpins bone loss in several debilitating skeletal diseases such as osteoporosis, metastatic breast cancer and multiple myeloma. Changes in remodelling activity can also arise as a consequence of therapeutic intervention for instance intravenous bisphosphonate treatment is associated with osteochemonecrosis of the jaw and localised osteoradionecrosis is a common side effect of radiotherapy. Hyperbaric oxygen is often used as an adjunctive therapy in the treatment of these disorders. HBO involves …

Motivated Reasoning And Response Bias: A Signal Detection Approach, Dries Trippas

Other Faculty of Science and Engineering Theses

The aim of this dissertation was to address a theoretical debate on belief bias. Belief bias is the tendency for people to be influenced by their prior beliefs when engaged in deductive reasoning. Deduction is the act of drawing necessary conclusions from premises which are meant to be assumed as true. Given that the logical validity of an argument is independent of its content, being influenced by your prior beliefs in such content is considered a bias. Traditional theories posit there are two belief bias components. Motivated reasoning is the tendency to reason better for arguments with unbelievable conclusions relative …

Beyond The Electronic Connection: The Technologically Manufactured Cyber-Human And Its Physical Human Counterpart In Performance: A Theory Related To Convergence Identities, Yacov Sharir

Other Faculty of Arts, Humanities and Business Theses

This thesis is an investigation of the complex processes and relationships between the physical human performer and the technologically manufactured cyber-human counterpart. I acted as both researcher and the physical human performer, deeply engaged in the moment-to-moment creation of events unfolding within a shared virtual reality environment. As the primary instigator and activator of the cyber-human partner, I maintained a balance between the live and technological performance elements, prioritizing the production of content and meaning. By way of using practice as research, this thesis argues that in considering interactions between cyber-human and human performers, it is crucial to move beyond …

High Fat Diet Induced Obesity In A Mouse Model For Colorectal Cancer, Kennerly Clinton Patrick

Obesity is widely correlated with the incidence of colorectal cancer (CRC). The exact mechanisms that link obesity to CRC risk have not yet been fully established, and only a limited number of animal models are available to study pathways involved in obesity-related colon carcinogenesis. The objective of this study was to determine the influence of HFD-induced obesity on AOM/DSS-mediated colorectal tumorigenesis, tumor proliferation, and symptom severity. Male C57BL/6 mice were fed a novel high fat diet, designed to mimic the standard American diet (12 % saturated fat & 28 % unsaturated fat), at 4 weeks of age until 16 weeks …

Places To Dream, Paulina Ochoa Espejo

Political Science Faculty Scholarship

The 2012 election showed that the Latino vote is a force that must be reckoned with, and this has revived discussions about the DREAM Act and Immigration Reform, particularly about the idea that those immigrants who are already here should be allowed to stay. But why does being physically present in a state’s territory entitle you to rights that you would not otherwise have? This paper examines arguments to grant rights to Dreamers based on membership and territorial presence, and argues that relation to place gives us better grounds for claiming that Dreamers have a right to stay.

Iii-V Nitride Micro- And Nano-Scale Cantilevers For Multimodal Sensing Applications, Ehtesham Bin Quddus

Theses and Dissertations

Recent research trends in chemical and biological sensing have been geared toward developing molecular sensor devices that are fast, label free, miniaturized and portable. The performance of these devices can be dramatically improved by utilizing multimodal detection techniques, new materials and micro-/nanofabrication technologies. This is especially true for micro-/nanoscale cantilever sensors, which undergo changes in mechanical or electrical properties upon the specific binding of molecules. To develop the sensor devices with the above attributes, we utilized III-V nitride materials: InN nanowires for realizing nanoscale cantilevers and AlGaN/GaN heterostuctures with or without embedded HFETs, for developing microcantilevers. There are mainly two …

Identity Crisis And The Emergence Of The Picaresque In Literature From Early Modern Spain And Twentieth Century Argentina, Mary Johnson Shepherd

Theses and Dissertations

The picaresque genre and character appeared in what is considered the first modern novel, Lazarillo de Tormes, which was published anonymously in 1554, when Spain was on the cusp of a slow transition out of feudalism. The pícaro has continued to appear in literature across regions and epochs. This thesis looks at the socio-ideological factors that give birth to picaresque identity and behavior, as well as the verisimilitude of fiction in relation to reality. The first part of this study is dedicated to the Spanish picaresque tradition and focuses on the universal qualities of the literary figure and genre, as …

Supply Chain Optimization Of Blood Products, Serkan Gunpinar

USF Tampa Graduate Theses and Dissertations

Major challenges in the management of blood supply chain are related to the shortage and wastage of the blood products. Given the perishability characteristics of blood which can be stored up to a limited number of days, if hospitals and blood centers keep an excessive number of blood units on inventory, wastages may occur. On the other hand, if sufficient number of blood units are not stored on inventory, shortages of this resource may cause the cancellations of important activities and increase the fatality rates at hospitals. Three mathematical models have been developed with the goal to improve the efficiency …

The Grotesque Museum In Dickens’ Great Expectations, Ehsan Hafezikermani, Roshanak Fazli

Khazar Journal of Humanities and Social Sciences

This novel is Dickens' thirteenth novel and was first printed in the weekly magazine All The Year Round in 1860 (GE Introduction, v). It is a Bildungsroman and its characters are developing through the story. So, Dickens, from the beginning, uses Pip as his camera to display almost everything using grotesquery elements in the novel. Pip makes different mental pictures in the story about most of the things, and it shows that he is changing his mind as he is growing up. So, the idea of grotesquery is evolving too; for instance, ideas of Pip about Magwitch are changed from …
