Bioinspired micropatterned adhesive surfaces for medical applications: a numerical investigation of fibrillar adhesives and swellable microneedle arrays
(NUI Galway, 2024-03-21)Traditional sutures and tissue adhesives can cause adverse effects, inflicting additional damage to the tissue, resulting in toxic chemical residues, and increasing the risk of infection. Bioinspired adhesives have ... -
Biosafety assessment during anaerobic co-digestion of food waste and pig manure
(NUI Galway, 2022-10-11)Antimicrobial resistance (AMR) spreading has been a public concern as it increases the mortality of infection, and some biowastes (such as pig manure, food waste and municipal waste sludges) have been reported as hotspots ... -
Building semantic models and knowledge graphs for intelligent smart manufacturing applications
(NUI Galway, 2024-04-04)Industry 4.0 (I4.0) (or smart manufacturing) is a new era in the industrial revolution that emphasises machine connectivity, automation, and data an alytics. This revolution has led to the creation of production lines ... -
Chemical Amendment of Dairy Slurry For The Control of Phosphorus in Runoff From Grassland
(2011-09-28)Phosphorus (P) loss from grassland to a waterbody can adversely affect water quality. Land application of dairy cattle slurry can result in incidental P losses to runoff in addition to increased chronic P losses from soil ... -
A computational and experimental investigation of the biomechanics of nickel-titanium stents for femoropopliteal applications
(NUI Galway, 2023-06-15)Self-expanding nickel-titanium stents are the current gold-standard in treating peripheral artery disease in the femoropopliteal artery. Despite this, failure rates in the femoropopliteal artery are much higher than ... -
A computational and experimental investigation of the dissection of arterial tissue
(NUI Galway, 2020-11-19)The overall objective of this thesis is to provide a new understanding of the mechanisms underlying arterial fracture, and to extend this understanding to the initiation and propagation of aortic dissection using a combination ... -
A computational and experimental investigation of the in-vivo biomechanics of the human aorta
(NUI Galway, 2020-07-06)The overall objective of this thesis is to provide a new understanding of the degree of biomechanical heterogeneity that exists along the human aorta, against the backdrop of clinical literature reporting that patient ... -
