Clay minerals and their gallery guests: an ab initio investigation into their interactions.
No full textClay minerals are ubiquitous and readily accessible in the natural environment and consequently have become an essential ingredient in the development of Western Society. Their structural properties are responsible for many of their uses, their layered-leaf composition enables the absorption of water and other solutes, for example. In this thesis, the focus of interest lies primarily in the chemical properties of the clay minerals, which is due to the large surface areas of varying atomistic environments comprising the mineral layers. Clay minerals offer a challenge to the electronic structure modeller as their atomistic composition is non-exact, consequently a number of constraints are automatically applied during the modelling process, the first being the choice of composition of the model. There are currently few examples of density functional theory studies using planewaves and the pseudopotential approximation, and the available experimental data is not necessarily directly applicable to theoretical data due in part, to the inexactness of the clay mineral composition. Consequently, in the studies presented in this thesis, as much time has been spent in considering the modelling methods as on the results obtained and the implication of these in the modelling environment chosen.
This thesis records investigations into the decarboxylation of a fatty acid into an alkane and CO with the modelling of a catalytic environment of an aluminium-bearing clay mineral; the identification of a transition state of this reaction pathway using lattice dynamics and finally, the mechanism of reduction within iron-bearing clay minerals

Postpartum Depression: Healing through Archetypes and the Expressive Arts Therapies
No full textThis thesis is a literature review investigating treating postpartum depression through the expressive arts therapies and feminine archetypes. The expressive arts therapies explored for treatment are dance, music, art, and drama. Meditation, mindfulness, and writing are also included. The importance of expressive arts therapies in treating postpartum depression is of interest now because of the increasing number of mothers who experience postpartum depression who are looking for alternatives to treatment beyond, or complementing, traditional talk therapy and medication. A search for literature on treating postpartum depression with expressive arts therapies and archetypes was conducted on-line using the Lesley University database. This research provides resources for women who are seeking to overcome postpartum depression in increasingly creative ways. The author will be presenting recommendations for incorporating this creativity in the lives of mothers. Recommendations for incorporating expressive arts therapy interventions for treating postpartum depression will include examples of integrating feminine archetypes for healing
Dance/Movement Therapy as a Potential Supplementary Treatment for Vasovagal Syncope: A Literature Review
No full textDance movement therapy has been utilized as an evidenced-based modality in treating numerous medical diagnoses. Despite its established efficacy in diverse medical contexts, little research exists on its application for vasovagal syncope, a condition often intertwined with mental health challenges. Although vasovagal syncope is situated in the body and frequently comorbid with mental health struggles that impact physiological symptoms, treatment options remain solely in the medical model. This literature review seeks to address this lack of research and adequate treatment options by highlighting the body/mind connection and advocating for dance/movement therapy as a potential supplementary treatment for vasovagal syncope. The author used personal experience with this diagnosis as well as Lesley @ll search and Google Scholar to gather research. The research explored is summarized through a description of the diagnosis, the physical and psychological impact, current treatment options, the use of dance/movement therapy with other medical and psychological diagnoses, and polyvagal-informed dance/movement therapy. The therapeutic qualities that emerged from the literature as important to treatment are therapeutic presence, embodied awareness, interoception, resilience, coping, empowerment, self-efficacy, and identity. It was concluded that dance movement therapy has the unique potential to support the body and mind of those struggling with vasovagal syncope supplementary to medical care. However, further research is needed to test this hypothesis

Isolation of Lipid Droplets from Cells by Density Gradient Centrifugation
No full textLipid droplets are organelles found in most mammalian cells, as well as various plant tissues and yeast. They are composed of a core of neutral lipids surrounded by a membrane monolayer of phospholipids and cholesterol into which specific proteins are embedded. This unit provides protocols for isolating lipid droplets from mammalian cells by discontinuous density gradient centrifugation
