A novel quantitative, sub-provincial approach to characterizing the shape of chlorophyll profiles
No full textBibliography: leaves 122-136.In this study, novel approaches such as artificial neural networks and generalized modelling have highlighted the variability in profile shape and enabled its improved prediction. This will lead to superior regional estimates of primary production

Lipid-soluble Vitamins A, D, and E in HIV-Infected Pregnant women in Tanzania.
No full textThere is limited published research examining lipid-soluble vitamins in human immunodeficiency virus (HIV)-infected pregnant women, particularly in resource-limited settings. This is an observational analysis of 1078 HIV-infected pregnant women enrolled in a trial of vitamin supplementation in Tanzania. Baseline data on sociodemographic and anthropometric characteristics, clinical signs and symptoms, and laboratory parameters were used to identify correlates of low plasma vitamin A (<0.7 micromol/l), vitamin D (<80 nmol/l) and vitamin E (<9.7 micromol/l) status. Binomial regression was used to estimate risk ratios and 95% confidence intervals. Approximately 35, 39 and 51% of the women had low levels of vitamins A, D and E, respectively. Severe anemia (hemoglobin <85 g/l; P<0.01), plasma vitamin E (P=0.02), selenium (P=0.01) and vitamin D (P=0.02) concentrations were significant correlates of low vitamin A status in multivariate models. Erythrocyte Sedimentation Rate (ESR) was independently related to low vitamin A status in a nonlinear manner (P=0.01). The correlates of low vitamin D status were CD8 cell count (P=0.01), high ESR (ESR >81 mm/h; P<0.01), gestational age at enrollment (nonlinear; P=0.03) and plasma vitamins A (P=0.02) and E (P=0.01). For low vitamin E status, the correlates were money spent on food per household per day (P<0.01), plasma vitamin A concentration (nonlinear; P<0.01) and a gestational age <16 weeks at enrollment (P<0.01). Low concentrations of lipid-soluble vitamins are widely prevalent among HIV-infected women in Tanzania and are correlated with other nutritional insufficiencies. Identifying HIV-infected persons at greater risk of poor nutritional status and infections may help inform design and implementation of appropriate interventions
Care home design for people with dementia: What do people with dementia and their family carers value?
No full textObjectives: To report on the views of people with dementia who live in care homes and their family carers on aspects of design that are important to them, and discuss these in relation to developing physical care environments that respond to the wishes of people with dementia and their family carers. Method: Six focus groups were held: two in Northern Ireland and four in Scotland. A total of 40 people participated in the focus groups. Twenty nine people were with dementia (24 female and five male), and 11 were family carers (10 female and one male). Results: Carers discussed the features of a building they took into account when selecting a care home, and discussed this in relation to ‘bricks and mortar versus people’. Key themes reported by people with dementia and their family carers included how the space in the environment is used, for example, what happens in the building and the presence or absence of certain design features. Outside space and wayfinding aids were identified as positive features of the home, along with a general lack of concern about ensuite provision. Conclusion: The results demonstrate the complexity of building design as it must provide living space acceptable to people with dementia living there and family members who visit, as well as provide a workable environment for staff. The findings highlight areas that should be considered by care home teams involved in the build of a new home or the redevelopment of an existing care home
(The) man, his body, and his society: masculinity and the male experience in English and Scottish medicine c.1640-c.1780.
No full textThis thesis examines the relationship(s) between medicine, the body and societal codes of masculinity in England and Scotland between c.1640 and c.1780. It responds to the way in which the men in histories of post-1660 masculinity are often disembodied, and to the comparative absence of men’s gendered experiences from the history of medicine. Its findings show that in both centuries the experience of being a man with a body that was the site of health and sickness was an open, candid, and often communal, one, inside and outside of the formal medical encounter. Thus, and on both sides of 1700, ill men had full freedom in the pursuit and acceptance of medical, familial and social assistance, while their physical suffering, and associated emotional distress, was met with sympathy. With their sick bodies the sites of honest self-examination and open discussion, it was in part this very public nature of their sicknesses that allowed men, as a gender and as individuals, independence and agency in their non-commercial health care. Indeed, later-seventeenth- and eighteenth-century men suffered no constraints in their ability to respond to the vulnerabilities of their bodies, even where this involved behaviours or attributes allegedly associated with women and femininity, or inconsistent with ideals of active, independent, masculinity.
These findings indicate, therefore, great continuity across the period 1640-1780, and not only in masculine ideals of and involving the male corporeality. There seems to have been significant consistency across time in men’s social and medical experiences of both sickness and their pre-emptive preparation for it, and in an apparent collective self-confidence concerning their corporeal masculinity, their sex, and, possibly, even their sexual potential. Indeed, these sources suggest that seventeenth- and eighteenth-century men had a resilient sense of self-identity (and personal masculinity), conceptually separable from the corporeal body and its known fragilities
Design and optimisation of a coreless superconducting synchronous generator
No full textConstantly increasing demand for electrical power requires more efficient and more powerful machines to be built. The conventional technology cannot provide such machines. It cannot deliver machines that are smaller, lighter and provide larger torques and power ratings. The answer to these problems is believed to be in superconducting machines.After short introduction to the phenomena of superconductivity and superconducting devices, practical superconducting tapes are described. The evolution and problems considered during the design of a coreless superconducting rotor for a synchronous machine are described. A few possible coreless rotor configurations are characterised and a simple formula is used to minimise the harmonic content.Estimation of machine parameters and evaluation of losses is also conducted. The areas to which particular attention has to be paid are pointed out. All these are undertaken for a demonstrator size machine with BSCCO windings. But to achieve real benefits it is important to build a machine that more closely represents real machines. Hence an optimisation method is used to investigate the possibility of increasing the size of the machine

Previously, harmonic Franck-Condon calculations for this transition were . The present calculations allow for anharmonicity in the ground state, although the upper-state potential is still assumed to be . The transition moment is taken to be proportional to the bending coordinate. For the calculation of the dispersed fluorescence it is found that the global potential surface of Halonen, Child and gives the best qualitative agreement for the intensities, but could be improved for the energies of high bending states
