Advancements in structural and functional imaging using Fourier domain optical coherence tomography
Lal, Cerine (NUI Galway, 2020-07-29)Optical Coherence Tomography (OCT) is a non-invasive optical imaging modality based on low coherence interferometry that enables high resolution, cross sectional imaging in biological tissues and materials. One major ... -
Carbohydrates in the synthesis of macrocycles and glycoclusters
Fox, Karen A. (NUI Galway, 2019-01-28)This thesis deals with efforts to generate new bioactive organic compounds. The main focus has been on the use of carbohydrate building blocks for synthesis of both macrocyclic compounds and glycoclusters for biological ... -
Chemical diversity of zoantharians from the coast of Ecuador in the tropical eastern Pacific
Guillen Mena, Paul Orlando (NUI Galway, 2019-09-18)This thesis describes the isolation and identification of marine natural products from five zoantharian species collected off the Marine Protected Area El Pelado located in Santa Elena, Ecuador. Ecuador is one of the ... -
Detection of faint exoplanets in multispectral data
Hanley, Kenneth (NUI Galway, 2019-04-15)The detection of extrasolar planets is extremely difficult due to their extreme faintness and proximity to their parent stars. Direct, ground-based detection is particularly challenging and despite the incredible contrast ... -
Entry pattern matrices
Ha Van, Hieu (NUI Galway, 2019-03-29)An entry pattern matrix (EPM for short) is a rectangular matrix in which each entry is an indeterminate. The same indeterminate may appear in multiple positions, but different indeterminates are independent. For a field ... -
Exploiting individual agent properties for analysis and control of collective network evolution
Galizia, Roberto (NUI Galway, 2021-02-24)In this thesis, we investigate linearly coupled dynamic networks made up of identical oscillators. We study the principles in which the dynamical features of the underlying constituent agents transfer to the collective ... -
Functional screening of human faecal microbiome metagenome library for glycoside hydrolase enzymes
Mulualem, Daniel (NUI Galway, 2020-04-24)Members of the human gut microbiota use glycoside hydrolase (GH) enzymes, such as sialidases, α-fucosidases and β-galactosidases to forage on host mucin glycans and dietary fibers. A human faecal metagenomic library was ... -
Hochschild (co)homology of two families of complete intersections
Nghia, Tran Thi Hieu (NUI Galway, 2020-01-08)The thesis presents the original results on a description of the ring structure in terms of generators and relations of the Hochschild cohomology of the two families of complete intersections: the square-free monomial ... -
Integrative taxonomy of sponges and cnidarians at "El Pelado" marine protected area (Santa Elena), Ecuador: Assessing the potential of metabolomics
Jaramillo Aguilar, Karla Belén (NUI Galway, 2020-01-23)In the course of the XXI century, the explorations of our oceans have moved towards the extremes with several highly funded projects to inspect remote places like the poles or the deep-sea. Does it mean that inventories ... -
Irish seagrass ecology and habitat mapping in the context of climate change
Beca-Carretero, Pedro (NUI Galway, 2019-01-28)Seagrasses play an important ecological role worldwide, providing numerous ecosystems services. Zostera marina is a dominant meadow-forming seagrass in temperate regions in the northern hemisphere, including Irish coasts. ... -
Mathematical models for the kinetics of some carbohydrate enzymes
Mai, Vinh Quang (NUI Galway, 2019-10-17)In this thesis, some mathematical models for the mechanism of action of carbohydrate enzymes are developed and analysed. Chapter 1 provides a general introduction to enzymes and their applications. In Chapter 2, ... -
Microbial processes mediating Priming Effects and the coupling of C and N cycling in soil
Waibel, Matthias (NUI Galway, 2020-10-31)Soil is fundamental to agricultural productivity and sustainability. Soil organic matter (SOM) is important as a “revolving nutrient fund”, which determines plant nutrient availability. Microbes are key determinants of SOM ... -
The neural network basis of cognitive impairment in bipolar disorder
McPhilemy, Genevieve (NUI Galway, 2020-01-22)Background: Despite well-documented cognitive deficits that contribute to poorer quality of life in bipolar disorder (BD) and evidence of altered topology and connectivity within neural networks, little work has been done ... -
The noble false widow Steatoda nobilis: Ecology, venom and potential medical importance
Dunbar, John (NUI Galway, 2020-08-21)The noble false widow spider Steatoda nobilis (Thorell, 1875) has expanded its range globally in recent years and may represent a potential threat to native ecosystems and public health. Our data shows that S. nobilis is ... -
Observational based evaluation of air-sea gas fluxes and turbulence in the surface ocean boundary layer
Esters, Leonie Tabea (NUI Galway, 2018-04-09)Turbulence within the ocean surface boundary layer (OSBL) is an important quantity for many processes as it mixes the ocean and transports various ocean quantities such as pollutants, heat, and dissolved gases. ... -
Photoacoustic imaging with clinical, preclinical, and quantitative applications
Breathnach, Aedán (NUI Galway, 2020-11-20)Photoacoustic (PA) imaging (PAI) is an emerging biomedical imaging modality that combines optical absorption contrast with ultrasonic resolution and imaging depth. Major research has been carried out into PAI in recent ... -
Plant-pollinator interactions in semi-natural grasslands: Evaluation, monitoring and conservation
Larkin, Michelle (NUI Galway, 2021-01-14)Pollinators provide a vital ecosystem service by pollinating many commercial and wild plant species. Agricultural intensification is one of the main drivers of global pollinator population declines, with consequences for ... -
Small-molecule-based crosslinking and bioconjugation of biomolecules
