Understanding Scoliosis: What Caregivers And Patients Need To Know, Megan Moore

Theses

Scoliosis is an abnormal curvature of the vertebral column that typically occurs in children approaching puberty. 80% of scoliosis cases are idiopathic (Scoliosis Research Society, 2022). The severity of a scoliosis curve is measured in degrees and is usually diagnosed when it is greater than 10 degrees. A severe curve exceeds 45 to 60 degrees and can require surgical treatment (Scoliosis Reduction Center, 2020). Severe scoliosis causes physical deformities, such as unaligned ribs, hips, and shoulders, but also may reduce the amount of space in the chest, affecting the function of the heart and lungs (Mayo Clinic, 2022). The purpose …

Modelling The Relationship Between Personality Traits And Basic Emotions: A Multi-Modal And Affective Computing Approach, Brendan Ryan Donovan

Theses

In the field of Psychology, it has long been assumed that one’s personality traits are linked to one’s emotional states. Yet there is a scarce amount of research that has directly quantified the relationships between basic emotional states and Big Five personality traits. Most empirical research has investigated how attributes of emotional states map to a narrow selection of personality traits (Extraversion and Neuroticism) via a single modality (questionnaires). This narrow focus restricts the field’s understanding of the relationship between emotional states and personality traits.

In this research, the Personality Emotion Mapping (PEM) model was developed to map the relationships …

The Use Of Membrane Filtration To Increase Native Whey Protein In Infant Formula, And Effects On Bioaccessibility And Bioactivity, Yihong Chen

Theses

Breastfeeding is recognised as the gold standard for feeding newborns and infants. However, infants who cannot be breast-fed or for whom breast milk is not available, can be fed with bovine infant milk formula (IMF) as a substitute. Researchers and producers of IMF strive to continually improve or “humanise” the composition and functionality of IMF. During production of IMF it must undergo several heat treatment steps, e.g. heat-sterilisation or spray-drying, in order to provide a safe product to the infant. These heat treatments denature the globular whey proteins in IMF. In contrast, breast milk is by its nature unheated, so …

Closing The Modern Irish Municipal Wastewater Phosphorus Cycle, Ciaran O’Donnell

Theses

Phosphorus (P) is an essential life-supporting nutrient for which there is no substitute. P naturally cycles within nature. Modern farming practice and food production have altered the natural P cycle. Successive crop harvests remove P from the soil as crops and transport them to urban areas to feed the population. To replace P removed from the soil through these crop harvests, mineral P fertilisers are applied to the soil to sustain crop production. Mineral P fertilisers are derived from finite phosphate rock. The European Union does not have an indigenous supply of phosphorus rock, which poses a significant issue for …
