Theoretical chemical kinetic study of the h-atom abstraction reactions from oxygenated species by different radicals
(2014-09-30)This work presents an ab-initio and chemical kinetic study of the H-atom abstraction reactions of ethers and ketones + HO2 radicals, aldehydes and acids + H atoms, OH, HO2 and CH3 radicals and esters + OH and HO2 radicals. ... -
Theoretical, experimental and modelling studies of the reactions of hydrogen atoms with C2 – C5 alkenes and cyclisation reactions of hydroperoxyl-alkyl radicals forming cyclic ethers and hydroxyl radicals
(NUI Galway, 2021-06-22)This thesis presents a hierarchical study of the reactions of Ḣ atom addition to and abstraction from both linear and branched C2 – C5 alkenes. The subsequent C–C and C–H β-scission reactions and H-atom transfer reactions ... -
Therapeutic applications of endothelial progenitor cells for diabetic ulcer healing
(2016-10-16)Diabetic ulcer healing is a major problem in health care. Impaired circulation has long been associated with diabetes resulting in an increased risk of foot ulceration and making an increase in blood flow an excellent ... -
Therapeutic potential of mesenchymal stromal cells in later phase antimicrobial resistant bacterial pneumosepsis: effects on the innate and adaptive immune system
(NUI Galway, 2023-08-25)Introduction: Sepsis is a dysfunctional immune response to infection and remains a major source of mortality worldwide. Sepsis can be divided into three stages: early, transitionary, and late phase with the early phase ... -
Therapeutic targets for duchenne muscular dystrophy
(NUI Galway, 2019-07-05)Duchenne Muscular Dystrophy (DMD) is a progressive X-linked fatal muscle degenerative disorder caused by the absence of the sarcolemmal associated dystrophin-glycoprotein complex (DGC) that connects the intracellular ... -
Therapies for acute respiratory distress syndrome: determination of the mechanisms of action of hypercapnia and the therapeutic efficacy of mesenchymal stromal cells
(2016-09-20)Rationale: Acute Respiratory Distress Syndrome (ARDS) causes severe respiratory failure and is associated with high mortality. Pharmacological therapies are non-existent and supportive ventilation treatments are limited. ... -
There should be recognition and protection of the privacy of children's identity and freedom for them to narrate their own online identity
(NUI Galway, 2023-03-21)Sharenting is a compound word derived from the words ‘parent’ and ‘sharing’ and, is defined as ‘the online posting of a child’s images and private details by parents with or without the child’s consent’.1 Parents share ... -
Thermal elevations of orthopaedic procedures: A bone cell perspective
(2014-05-27)Thermal elevations experienced by bone during orthopaedic procedures, such as cutting and drilling, exothermal reactions from bone cement, and thermal therapies such as tumour ablation, can result in thermal damage leading ... -
A thermodynamically motivated investigation of cell and tissue remodelling
(NUI Galway, 2018-08-24)The overall objective of this thesis is to provide a new understanding of the mechanisms that drive cell spreading and remodelling, and to extend this understanding to remodelling at a tissue and organ level. A steady-state ... -
Thermomechanical Analysis of P91 Power Plant Components
(2014-01-17)This thesis presents a combined experimental and computational study on the thermo-mechanical fatigue performance of welded P91 material to (i) characterise the thermomechanical behaviour, and (ii) predict the number of ... -
Thinning instabilities in biological and electroactive membranes
(NUI Galway, 2018-10-31)This thesis addresses several problems in the mathematical modelling of biological and electroactive membranes. We begin with a review of the necessary scientific background of biological and electroactive membranes. ... -
Three essays on renewable natural resources (forestry & fisheries) management problems in the Republic of Ireland
(2015-05-22)The objective of this thesis is to answer two problems related to the provisioning of forest ecosystem services and one problem related to the provisioning of aquatic ecosystem services in Ireland through three empirical ... -
Three essays on the impact of the Common Agricultural Policy on Irish farms
(2014-03-31)Since its establishment by the Treaty of Rome in 1958, the Common Agricultural Policy (CAP) has had a huge impact on the agricultural sector in Europe and more widely. The original CAP altered production incentives, ... -
Three-dimensional Magnetotelluric Inversion
(2008-01)The main objective of my PhD research is developing a better understanding of the mathematics, physics and numerical aspects of 3D MT inversion. This should lead to a working software that allows inversion of MT datasets ... -
Three-layer collagen-based composite scaffolds to spatially direct tissue-specific cell differentiation for enthesis repair
