A Portable, Digital Nucleic Acid Amplification Test For Use At The Point Of Care, Bethany J. Fike Jan 2024

A Portable, Digital Nucleic Acid Amplification Test For Use At The Point Of Care, Bethany J. Fike

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nucleic acid tests are key tools for the detection and diagnosis of many diseases. In many cases, the amplification of nucleic acids is required to reach a detectable level. Although nucleic acid tests have great success, there is a need to make nucleic acid amplification tests more accessible to a point-of-care (POC) setting for diagnosis, prognosis, and monitoring of infectious diseases. Traditionally, these tests are performed through bulk Polymerase Chain Reaction (PCR) and are monitored in real time with a change in fluorescence intensity. With these bulk testing methods, only a qualitative or semi-quantitative result is possible. For more exact …

The Challenge Of Securing Future Food Production For Aquaculture Species Under Environmental Change: Enhancing Physiological Performance Under Environmental Stress, Ahmed Salama Ali Abbas Jan 2024

The Challenge Of Securing Future Food Production For Aquaculture Species Under Environmental Change: Enhancing Physiological Performance Under Environmental Stress, Ahmed Salama Ali Abbas

School of Biological and Marine Sciences Theses

Rising sea surface temperatures and ocean acidification present profound challenges for many marine species, leading to cascading effects on ecosystem functionality and food security. Phenotypic plasticity is anticipated to play a key role in helping marine ectotherms maintain performance and acclimate to changes in these global environmental drivers. However, our understanding of phenotypic plasticity in the context of climate change is largely based on short-term studies, with limited ecological relevance, which often overlook some important response modifiers such as environmental context, exposure nature, reproductive modes, and potential trade-offs between fitness components. As a result, the full potential for marine ectotherms …

Ecosystem-Scale Patterns In The Diversity, Seasonal Dynamics And Physiology Of Antagonistic Diatom-Bacteria Interactions In The Western English Channel, Laura Branscombe

School of Biological and Marine Sciences Theses

Diatoms, a major group of marine and freshwater microalgae, are one of the most successful phototrophic organisms in the oceans. Their ubiquity and abundance pins them as important drivers of marine biogeochemical cycles and significant components of marine food webs. Diatoms exist within a complex web of interactions with other microbes, including equally ubiquitous marine bacteria. Interkingdom interactions between diatoms and bacteria are both diverse and numerous, and they underpin the success of diatoms through their resulting impacts on diatom physiology. Interactions between diatoms and antagonistic bacteria are increasingly recognised to significantly impact diatom growth and physiology, and potentially represent …

Mapping The ‘Particlescape’: Diversity And Activity Of Microbial Communities Associated With Particles In The Marine Environment., Cordelia Roberts Jan 2024

Mapping The ‘Particlescape’: Diversity And Activity Of Microbial Communities Associated With Particles In The Marine Environment., Cordelia Roberts

School of Biological and Marine Sciences Theses

Particles are hotspots for marine microbial communities and impact ecosystem functioning, including the biological carbon pump. Although particle microbiomes differ across particle composition, type, size, source, and life history, this heterogeneity is often overlooked by using bulk-scale sampling approaches. In addition, knowledge of microbial eukaryotes in particle microbiomes is limited. I broadly set out to investigate how particle associated communities are structured at the macro and micro-scale which may have implications for wider food web interactions and biogeochemical cycling. In independent research chapters, I examined the diversity of bacteria (chapter 1) and activity of microbial eukaryotes associated with organic material …

Intraspecific Differences In The Metabolic Response Of Amphipods To Elevated Co2 And Hypoxia, Emma Ingrid Zandt Jan 2024

Intraspecific Differences In The Metabolic Response Of Amphipods To Elevated Co2 And Hypoxia, Emma Ingrid Zandt

School of Biological and Marine Sciences Theses

Periodic episodes of low oxygen (hypoxia) and elevated CO2 (hypercapnia) accompanied by low pH occur naturally in Norwegian fjord systems. Under the influence of climate change, the geographic range and intensity of hypoxia and hypercapnia are predicted to increase, especially considering the phenomenon of Arctic amplification. To examine the metabolic variability and physiological capabilities of amphipods to these stressors, a series of physiological measurements were performed on latitudinal subpopulations (60° and 69°) of the amphipod Echinogammarus marinus, acclimated to different natural thermal regimes. The effects of elevated pCO2 and hypoxia, separate and together, on thermal sensitivity (Q10), metabolic rate, activation …

Application Of Deep-Learning To Deep-Sea Species Identification From Image-Based Data, Eleanor Cross Jan 2024

Application Of Deep-Learning To Deep-Sea Species Identification From Image-Based Data, Eleanor Cross

School of Biological and Marine Sciences Theses

Vast areas of the world’s deep sea are unexplored, and the recent threats of deep-sea mining and trawling make exploration of these habitats a time-sensitive concern. Much of our understanding of the deep sea has been based on physical sampling of sediment habitats using trawls and grabs, however, modern methods of surveying the deep sea involve the acquisition of video footage using Remotely Operated Vehicles (ROVs). Use of image-based methods is particularly important for sensitive or vulnerable species such as cold-water corals, especially considering these species tend to inhabit hard substrate areas that cannot be sampled using trawls. Annotation of …

Physical Drivers Of Ecosystem Change Throughout The Tropical Indian Ocean, Ted Robinson Jan 2024

Physical Drivers Of Ecosystem Change Throughout The Tropical Indian Ocean, Ted Robinson

School of Biological and Marine Sciences Theses

The past decade has seen improved awareness of increasing anthropogenic stress on marine ecosystems and their inhabitants. To understand how best to protect these ecosystems, it is vital to understand the linkages between physical oceanographic processes and ecosystem variability. To date there have been limited multidisciplinary investigations capable of resolving both local oceanographic influences and ecosystem response at tidal and interseasonal time scales. Here we present findings from three multidisciplinary research cruises to Chagos Archipelago, investigating the dynamics at Egmont, a tropical atoll, and Sandes, a shallow steep sloped seamount pinnacle. Our findings are then applied in a case study …

Predictors Of Weight Gain In The Rehabilitation Of Eastern North Atlantic Grey Seals (Halichoerus Grypus), Samantha Mcgivern Jan 2024

Predictors Of Weight Gain In The Rehabilitation Of Eastern North Atlantic Grey Seals (Halichoerus Grypus), Samantha Mcgivern

School of Biological and Marine Sciences Theses

As large adult body size is subjected to strong selective pressures, other processes can be compromised before growth when there is resource limitation or stress during the growth phase. Stress has been linked with both weight loss and weight gain in a variety of taxa, and some stressors, such as physical disturbance, are known to affect the development of important physiological processes, e.g., diving physiology in marine mammals. With 40% of the world’s grey seal (Halichoerus grypus) population on UK shores, grey seal pups are frequently admitted to rehabilitation centres within their first four weeks – a crucial growth phase …

Using Thermal Imaging Data To Explore Behaviour In A Critically Endangered Frog Species, Craugastor Ranoides, Victoria Wakeham Jan 2024

Using Thermal Imaging Data To Explore Behaviour In A Critically Endangered Frog Species, Craugastor Ranoides, Victoria Wakeham

School of Biological and Marine Sciences Theses

Understanding a species behaviour, in particular behavioural thermoregulation, is important as it can indicate how well the species will adapt to changing environments, such as climate change. Ectotherms are particularly vulnerable to the effects of climate warming as they rely on environmental conditions to regulate their body temperature and physiological functions. Thermal imaging can be used as a non-invasive method to study thermal behaviour. Thermal images measure the surface temperature of species as well as surrounding substrate. The present study used Craugastor ranoides, to gain insights into different behaviours at population level: behavioural thermoregulation, and using temperature variation across the …

Investigating Trade-Offs In Strength, Skill And Vigour In Pagurus Bernhardus, Joshua Le Pla Jan 2024

Investigating Trade-Offs In Strength, Skill And Vigour In Pagurus Bernhardus, Joshua Le Pla

School of Biological and Marine Sciences Theses

The ability to win contests is vital for securing the valuable resources individuals need for survival, or in some cases to secure mating opportunities. Therefore, fighting can have a strong influence over fitness, and much research has been carried out to identify and understand the traits influencing fighting ability, also known as resource holding potential (RHP). RHP has been found to be influenced by a wide range of factors including morphology, physiology, vigour and, more recently, skill. These factors are typically analysed in isolation from one another, so as to identify the individual impact of each trait. However, to gain …

Using Ecosystem Services Mapping In Deep-Sea Marine Spatial Planning, Giulia La Bianca Jan 2024

Using Ecosystem Services Mapping In Deep-Sea Marine Spatial Planning, Giulia La Bianca

School of Biological and Marine Sciences Theses

Assessing and mapping ecosystem services (ES) has emerged as an important practice to support natural resource management and set conservation priorities. This is recognised as useful in enabling simultaneous attainment of socio-economic and ecological goals. Yet there exists a bias towards assessing ES in terrestrial and coastal systems. Deep-sea applications are particularly scant. Assessing ES provided by the deep sea is undermined by the lack of ecological data and scientific understanding of the links between ecosystem components and human well-being. Thus, novel tools are required to translate existing deep-sea ES knowledge into Marine Spatial Planning (MSP), while maintaining acceptable levels …

Identifying And Quantifying Pelagic Organisms Around Seamounts, Atolls, And Islands In The Chagos Archipelago In Relation To Local Oceanographic Processes, Dannielle Sophie Eager Jan 2024

Identifying And Quantifying Pelagic Organisms Around Seamounts, Atolls, And Islands In The Chagos Archipelago In Relation To Local Oceanographic Processes, Dannielle Sophie Eager

School of Biological and Marine Sciences Theses

Topographic features, such as seamounts and atolls, are commonly identified as biodiversity hotspots that are key areas of productivity in an otherwise oligotrophic Indian Ocean. Whilst these sites of increased biomass are frequently identified, the oceanographic drivers that underpin the spatiotemporal distributions of biomass are not. If effective conservation measures are to be continued and implemented in regions such as the Chagos Archipelago Marine Protected Area (MPA) then the spatial variability of biomass and the physical drivers must be elucidated. This study presents case studies at Sandes seamount and Egmont atoll in the Chagos Archipelago identifying the distributions and behavioural …

'Man's Forgotten Friend': Dogs Appointed As Domesticated Companions And The Coronavirus Pandemic, Rebekah Gregory Jan 2024

'Man's Forgotten Friend': Dogs Appointed As Domesticated Companions And The Coronavirus Pandemic, Rebekah Gregory

School of Law, Humanities and Social Sciences Theses

The metaphorical confinement of national lockdowns saw the egocentric adoption of dogs appointed as domesticated companions. While public approval of ‘animal’ welfare legislation and the growing popularity of ‘green’ theory and industry has grown, ‘animals’ are still victim to the consumer and the anthropocentric cultures which promote individual, economic, social, and specifically ‘human’ advancement at all costs. Even though the reasons why ‘animals’ are victimised has been researched, how the pandemic has impacted upon this treatment and consumer culture’s/anthropocentrism’s influence has been somewhat absent within academic discussion. In fact, how the global events of COVID-19 have impacted upon dog treatment, …

Quantitative Raman Analysis Of Human Blood Serum Of Glaucoma Patients Supplemented With Macular Pigment Carotenoids., Joy Udensi, Ekaterina Loskutova, James Loughman, Hugh J. Byrne

Datasets

Carotenoids have been widely studied for their high dietary, antioxidant, and vision protection roles in the human body. Blood contains all major dietary carotenoids and hence presents as a suitable and efficient substrate for the estimation of dietary carotenoids in vivo. Following the 18-month supplementation of open angle glaucoma patients with macula pigment carotenoids (Lutein, Zeaxanthin and Meso-Zeaxanthin) in the European Nutrition in Glaucoma Management (ENIGMA) trial, Raman spectroscopic analysis of the pre-supplementation baseline and 18-month supplemented blood serum carotenoids from participants was carried out, to investigate the systemic impact of supplementation in the blood and explore a more direct …

Synthetic Microbial Communities For Plastic Upcycling, Isabel B. A. Valencia Jan 2024

Synthetic Microbial Communities For Plastic Upcycling, Isabel B. A. Valencia

Dissertations, Master's Theses and Master's Reports

Plastic waste and human hunger pose major threats to the health and wellbeing of populations world-wide. Using microbial methods to upcycle polyethylene terephthalate (PET) plastic into value-added compounds such as single cell protein (SCP) for human consumption is a unique solution to both these issues. Two monomers of chemically deconstructed PET (DCPET), terephthalate (TPA) and ethylene glycol (EG), have been previously shown to be biodegradable by enriched microbial communities. Using this top-down knowledge to inform the reconstruction of a minimal microbial community constructed from isolated members of these communities is a novel way to efficiently process these monomers via a …

Using A Reverse Visually Guided Reaching Task To Distinguish Between Healthy Aging And Early Alzheimer’S Disease, Brandon Woolman Jan 2024

Using A Reverse Visually Guided Reaching Task To Distinguish Between Healthy Aging And Early Alzheimer’S Disease, Brandon Woolman

Dissertations, Master's Theses and Master's Reports

Changes in motor behavior may function as a proxy for cognitive decline. While Alzheimer's disease (AD) is associated with impairments in learning and memory, recent studies suggest that subtle changes in motor task performance may reflect early cognitive changes. For example, the visuomotor rotation task that manipulates visual feedback about hand position during reaching movements, can be used to examine cognitive changes in aging populations. The current study used the reverse visually guided reaching task (rVGR) which rotates visual feedback of participant’s hand position 180⁰ relative to the actual hand position. We sought to expand on previous literature by recruiting …

Understanding Subtle Gender Bias Recognition Among Witnesses In A Stem Undergraduate Context, Darnishia Lashalle Morris

Dissertations, Master's Theses and Master's Reports

This dissertation builds on knowledge of how witnesses recognize subtle gender bias (often referred to as gendered microaggressions) in a STEM undergraduate context. This body of work provides a better understanding of the implications of observing these events of subtle bias and the role that recognition plays in providing opportunities to adopt stereotype defying behaviors. The impressions and influences on both witnesses who belong to the marginalized group (target witnesses) and those in majority groups (non-target witnesses) were examined. Three interrelated studies explored how recognition might disrupt the cyclic impact of subtle gender bias when participants witness collaborative STEM team …

Gravity Fed Hopper Flow Of Bulk Solids For Lunar Isru, Jason Bendixen Noe Jan 2024

Gravity Fed Hopper Flow Of Bulk Solids For Lunar Isru, Jason Bendixen Noe

Dissertations, Master's Theses and Master's Reports

With the return to the moon in the decade of the 2020s, there has been a renaissance of lunar technology development and innovation. This has been particularly true for the area of lunar ISRU (In-Situ Resource Utilization). One key area in ISRU that has been neglected is lunar regolith storage hopper research. Many lunar regolith ISRU researchers use storage hoppers in their work but do not document the properties when designing the hoppers or do not have the information at hand. Because of this, hopper design and documentation are poorly understood, and more research is needed. Hoppers are vital for …

Mechanical Properties And Cycling Fatigue Of Zn-Based Alloys: Effects Of Thermal Treatment, Henry D. Summers Jan 2024

Mechanical Properties And Cycling Fatigue Of Zn-Based Alloys: Effects Of Thermal Treatment, Henry D. Summers

Dissertations, Master's Theses and Master's Reports

Zinc (Zn)-based alloys are attractive candidate materials for constructing bioresorbable coronary stents because of their near-ideal corrosion properties and biocompatibility. These alloys are primarily strengthened through alloying and thermomechanical processing by solid solution strengthening, grain refinement, and precipitate strengthening. The microstructural features responsible for these strengthening mechanisms are controlled through the thermal treatment of the alloys. While the static mechanical properties of Zn alloys have been studied, a gap in the literature remains related to their mechanical stability under dynamic loading conditions (fatigue) and creep, especially while subjected to physiological conditions. This work aims to characterize the effects of thermal …

The Integration Of Neuromorphic Computing In Autonomous Robotic Systems, Md Abu Bakr Siddique

Dissertations, Master's Theses and Master's Reports

Deep Neural Networks (DNNs) have come a long way in many cognitive tasks by training on large, labeled datasets. However, this method has problems in places with limited data and energy, like when planetary robots are used or when edge computing is used [1]. In contrast to this data-heavy approach, animals demonstrate an innate ability to learn by communicating with their environment and forming associative memories among events and entities, a process known as associative learning [2-4]. For instance, rats in a T-maze learn to associate different stimuli with outcomes through exploration without needing labeled data [5]. This learning paradigm …

Matrix Stiffness Sensing By Nascent Adhesions And The Role Of Riam In Adhesion Assembly, Nikhil Mittal Jan 2024

Matrix Stiffness Sensing By Nascent Adhesions And The Role Of Riam In Adhesion Assembly, Nikhil Mittal

Dissertations, Master's Theses and Master's Reports

Mechanical stiffness of the extracellular matrix (ECM) impacts many cellular functions such as proliferation, migration, and differentiation. ECM stiffness is sensed by a cell via integrin-based focal adhesions (FAs) by changing conformation and biochemical activities of molecules within FAs by the exchange of the force between the ECM and filamentous actin (F-actin). Cells in turn respond to this stiffness by generating traction force that plays an important role in many biological events such as tissue morphogenesis, stem cell differentiation, wound healing, and cancer cell metastasis. The stiffness of the extracellular matrix induces differential tension within integrin-based adhesions. Understanding stiffness sensing …

Chemical Synthesis Of Sensitive Dna, Komal Chillar Jan 2024

Chemical Synthesis Of Sensitive Dna, Komal Chillar

Dissertations, Master's Theses and Master's Reports

Over the past decades, researchers have tried various chemical methods to synthesize modified oligodeoxynucleotides (ODNs, i.e. short segments of DNAs). Traditional ODN synthesis methods require strong basic, and nucleophilic conditions for the deprotection and cleavage of the ODN from the solid support. However, the sensitive ODNs containing labile functionalities are vulnerable to such harsh conditions. Sensitive ODNs have a wide range of applications in research and pharmaceuticals. To synthesize sensitive ODNs, researchers devised different strategies but no practical methods have been developed. To overcome these challenges, we developed alkyl Dim alkyl Dmoc technology. This innovative technology uses weakly basic and …

Examining Genome Size And Nutrient Influence On Damage Patterns, And Plant-Invertebrate Community Dynamics, Hailee B. Petosky Jan 2024

Examining Genome Size And Nutrient Influence On Damage Patterns, And Plant-Invertebrate Community Dynamics, Hailee B. Petosky

Dissertations, Master's Theses and Master's Reports

Genome size (GS) varies widely among angiosperms and has been shown to mediate plant responses to nutrients. Variations of GS drastically impact plant growth, fitness, and competitive responses, influencing plant functioning, nutrient requirements, and potentially, consumptive interactions. Specifically, plants with larger genomes vary in their cellular nutrient requirements, affecting tissue quality, nutrient constraints, and invertebrate interactions. Furthermore, environmental nutrient enrichments are a key driver affecting ecosystem functioning and species interactions. Plant communities are impacted by both top-down and bottom-up controls of herbivores and nutrients, respectively, and alterations to these interactions may cause cascading trophic level effects to influence damage patterns …
