Multi-element soil analysis is now an established technique in archaeology. It has been used to locate archaeological sites and define the extent of human activity beyond the structural remains, and to aid interpretation of space use in and around archaeological remains. This study aimed to evaluate the consistency of these soil element signatures between(More)
PURPOSE To determine the feasibility in a middle-level human development country of onsite training, image collection, Internet transfer, and remote grading of digital retinal images from babies screened for retinopathy of prematurity (ROP). METHODS Two experienced nurses in a neonatal nursery in Lima, Peru, were trained to take posterior pole (30 degrees(More)
Radioactive 'hot particles' that occur in the environment present specific challenges for health and environmental regulators as often their small size makes them difficult to detect, and they are easily dispersed and accidentally ingested or inhaled by members of the public. This study of nine hot particles recovered from the beach at Dalgety Bay, UK, uses(More)
In this paper the research draws upon reminiscence therapy, which is used in treating dementia, as an applied theory to promote well being in people who experience low moods. The application proposed here aims to promote wellbeing for people suffering from mood disorders and dementia but could potentially be used to enhance wellbeing for many types of(More)
This exploratory study aimed to assess whether ubiquitous devices could be used to facilitate person-centred reminiscence therapy. In order to test this approach to delivering a reminiscence therapy intervention, a tablet application was designed (using participatory design) and tested by the carers of people with dementia. The study showed that there is(More)
Description: Soil micromorphology deals with the microscopic study of undisturbed soil and regolith samples, making use especially of thin sections and petrographic techniques. It exists as a discipline for almost 70 years. Micromorphology is used by pedologists, quaternary geologists, sedimentologists, and since two decennia intensively by archaeologists.(More)
There is a professional responsibility placed upon archaeologists to record all possible information about a given excavated site of which soil analysis is one important but frequently marginalised aspect. This paper introduces SASSA (Soil Analysis Support System for Archaeologists), whose primary goal is to promote the wider use of soil analysis techniques(More)
Enhanced soil element concentrations may serve as indicators not only of modern pollution, but also of former historic and/or pre-historic human activity. However, there is little consensus over the most appropriate means of extraction for identifying chemical signatures of modern and archaeological pollution. This study addressed this question by using a(More)
PURPOSE Retinopathy of prematurity (ROP) is a disorder of developing retinal blood vessels in preterm infants. The purpose of this nested study was to investigate the effects of higher (91-95%) and lower (85-89%) oxygen saturation (SpO2) targeting on retinal blood vessel growth in preterm infants. METHODS Retinal blood vessel growth in the higher (91-95%)(More)
