Invasive Interactions
… the body of work developed for my thesis, Invasive Interactions, which represents abstracted trees as a metaphor for humanistic situations. Through my forms I will discuss equality, abuse, isolation, community, and at the fundamental level, nature itself. Invasive Interactions was created …

Clinical, Invasive and Non-Invasive Factors Affecting Outcomes in Patients with Acute Coronary Syndromes
In this thesis, factors affecting outcomes after percutaneous coronary intervention (PCI), the most common interventional procedure performed, were examined. To constrain procedural costs, selective criteria for drug-eluting stents (DES), which reduce restenosis, were developed in 2003 at Liverpool …

EXPLORING PHYSIOLOGICAL, PATHOLOGICAL AND PARAPHYSIOLOGICAL BRAIN ACTIVITY ACROSS SCALES WITH SIMULTANEOUS INVASIVE AND NON-INVASIVE EEG
This thesis explores the integration of non-invasive high-density electroencephalography (hd-EEG) with invasive stereoelectroencephalography (SEEG) to enhance understanding of brain electrophysiology in pathological, physiological and paraphysiological contexts. The combination of these two …

Comparison of Invasive and Non-Invasive Techniques for Measuring Fiddler Crab Density in a Salt Marsh
Quantifying the density of burrowing crabs is challenging, and several techniques have been developed to accomplish it, including burrow counting, visual surveys of surface-active crabs, and substrate excavation. These techniques have been compared in mangrove forests but not in a salt marsh, nor …

Invasive species: fundamental and applied science
Management of invasive alien species (IAS) is notoriously difficult, with many examples of expensive, failed attempts. While there is growing consensus that prevention is better than cure, successful prevention requires user-friendly, effective methods to quantify the ecological impacts of …

Non-Invasive and Invasive Assessment of Carbohydrate Intakes and Muscle Glycogen Utilisation in Rugby League and AFL
… has traditionally been performed through the invasive muscle biopsy technique. However, recent data from laboratory-based cycling studies suggests that ultrasound technology (using commercially based software known as MuscleSound) provides a valid and non-invasive assessment tool for which to …

An Invasive Species as a Threat to Native Biodiversity: Larval Competition Between Native Anurans and an Invasive Treefrog
… established in Florida and Louisiana and have invasive potential further westward, possibly impacting native anurans at multiple life stages. In anurans, competition at the larval stage can decrease adult fitness through slower development and smaller size at metamorphosis, ultimately …

Non-Invasive Intracranial Pressure Method and Monitor
The eyes are acoustically continuous with the brain and inner ear tissues in regard to matched impedances, based on tissue densities, thus, vibration of one site will be reflected in all sites. With this being the case, the vibrational energy response of the eye due to an external source can be …

Non-invasive in vivo ultrasound temperature estimation
… has emerged as a promising modality for noninvasive surgery due to its ability to create precise mechanical and thermal effects at the target without affecting surrounding tissues. An essential element in all these procedures, however, is accurate estimation of the target tissue temperature …

Landfill design, construction and non-invasive monitoring
Three techniques are investigated in order to assess their applicability for use in landfill design, construction and monitoring. Firstly, an assessment is made of QA procedures during liner construction through the detailed evaluation of two case studies. Construction QA procedures on-site are …

Non-invasive diagnostic methods of intracranial arteries
Aims of this thesis were to compare the agreement of different magnetic resonance angiography(MRA) techniques and digital subtraction angiography (DSA) in follow-up of intracranial aneurysms treated with coils in order to select the best MRA method, to evaluate the impact of increased iodine …
