Abstract:
Devastated by the mysterious death of her guardians, Elizabeth Davenport finds herself thrust into a new world that proves to be scintillating and dangerous. Can she trust those who claim to be her friends? Or will her trust lead her into trouble? When a mysterious letter presents itself and proves that her guardians might have been more than they ever let on, Elizabeth must gather her courage and pursue the truth, whatever the cost.

Abstract:
The capacity of zoonotic pathogens to infect multiple hosts creates surveillance challenges but also provides opportunities to gather data from animal species that can be used to understand risks to human health. This thesis presents a conceptual and practical assessment of the utility of domestic dog serosurveillance for the detection and surveillance of two pathogens, influenza A and Leptospira spp. The first chapter gives a theoretical framework that can be used to explore the attributes of animal sentinels and assess their utility in different contexts.

Abstract:
Sentinel lymph node biopsy (SLNB) is currently performed using radioisotope and blue dye injections. Drawbacks to using radioisotopes include exposure to radiation, limited global availability and a short half-life. A newly developed magnetic technique for identification of sentinel lymph nodes (SLNs) can overcome these problems. The magnetic technique is nonradioactive as it uses iron oxide particles as a magnetic tracer. The tracer causes a brown colour change in the SLN, which is visualised at surgery and it can be localised intraoperatively using a handheld magnetometer. The aims of this t

In the past 40 years, floods have become a bane of Mozambique’s inhabitants and economy. The latest of them, caused by the cyclone Idai, has devastated the area resulting in loss of life and property. It was estimated that around 715 000 hectares of farmland was destroyed as a result of the cyclone. The main goal of this thesis was to assess the extent of the flooding and to determine the types of land cover that were affected. This was done in Google Earth Engine, using SAR change detection on Sentinel 1 data to create a mask for the flooded areas, followed by a supervised image classificatio

Land use and land cover maps can support our understanding of coupled human- environment systems and provide important information for environmental modelling and water resource management. Satellite data are a valuable source for land use and land cover mapping. However, cloud-free or weather independent data are necessary to map cloud-prone regions. Merging radar with optical images would increase the accuracy of the study. Agricultural land cover is characterized by strong variations within relatively short time intervals.

The most important prognostic indicator in early cancer is whether the disease has metastasised to regional lymph nodes. Pre-operative imaging is not sensitive enough to detect micrometastatic deposits therefore most patients judged to have more than 20% risk of disease spread will have elective surgical removal of the draining lymph node basins in order to reduce the risk of leaving tumour behind. Such operations can be lengthy and associated morbidity can reduce the patient’s quality of life. In the majority of these elective nodal clearances histopathological analysis is clear of disease in

Abstract:
Lymphoscintigraphy has been used for many years to study the physiology of the lymphatic drainage of the skin. Following the intradermal injection of 99mTc antimony sulphide colloid images can be obtained using a gamma camera which display the pattern of lymphatic drainage from the injection site. When we first started performing the lymphatic mapping studies for patients of the Sydney Melanoma Unit we were using the study to clarify flow patterns in patients who had melanomas in skin sites which were considered on clinical grounds to have ambiguous lymphatic drainage. These were sites close t

Abstract:
Les eaux de surface sont des ressources importantes pour la biosphère et l'anthroposphère. Elles favorisent la préservation des habitats, le développement de la biodiversité et le maintien des services écosystémiques en contrôlant le cycle des nutriments et le carbone à l’échelle mondiale. Elles sont essentielles à la vie quotidienne de l’homme, notamment pour l'irrigation, la consommation d’eau potable, la production hydro-électrique, etc. Par ailleurs, lors des inondations, elles peuvent présenter des dangers pour l'homme, les habitations et les infrastructures. La surveillance des changemen

Abstract:
En Afrique de l'Ouest, la cartographie des jachères est essentielle pour caractériser les systèmes agricoles et évaluer avec précision la durabilité agroécologique des pratiques actuelles et leur contribution à la sécurité alimentaire. Cependant, les méthodes actuellement disponibles pour la cartographie des surfaces cultivées ne sont pas adaptées aux conditions environnementales et culturales rencontrées en contexte d'agriculture familiale en Afrique sub-saharienne. Dans cette thèse de Doctorat, plusieurs stratégies de cartographie des jachères basées sur des approches de classification super
