Outputs from a volcanic ash transport and dispersion model (NAME) for the 2019 Raikoke eruption
No full textThis dataset contains the output of a volcanic ash transport and dispersion model (Numerical Atmospheric-dispersion Modelling Environment - NAME) simulations of the 2019 Raikoke eruption.
This set of simulations is used to investigate the impact of the structual choices made in the setup of NAME to along-flight peak ash concentration and dosage calculations. The following parameters are varied: temporal resolution, horizontal resolution and number of particles released per hour in the simulations
Dataset and R Code supporting results from 'Biological traits predict ability of British wild bees to occupy their climate envelopes'
No full text***This dataset has been withdrawn: An updated version of the dataset is available at https://doi.org/10.17864/1947.001423***
This dataset contains number of records, size of climate envelopes, range filling abilities and biological traits used to produce analysis in the manuscript "Biological traits predict ability of British wild bees to occupy their climate envelopes"
This data is derived from presence-only bee observations provided by the Bees, Wasps and Ants Recording Society (BWARS - www.bwars.com)
Dataset and R code supporting results from 'Spatio-temporal shifts in British wild bees in response to changing climate'
No full textThis dataset contains estimates of emergence dates for 88 species of British bees from 1980-2019, and R script to reproduce the results from the manuscript 'Spatio-temporal shifts in British wild bees in response to changing climate'.
This data is derived from presence-only bee observations provided by the Bees, Wasps and Ants Recording Society (BWARS - www.bwars.com), and temperature data from the E-Obs and CHESS-SCAPE projects
Time-lapse imaging datasets of Belousov-Zhabotinsky self-oscillating hydrogels under cyclic mechanical compressions
No full textThis dataset contains all relevant experimental datasets that were collected for Tunde Geher-Herczegh's PhD thesis 'A study of chemical-mechanical coupling in Belousov-Zhabotinsky self-oscillating hydrogels, towards the physical-chemical model of the heart', in the form of time-lapse image sequences of Belousov-Zhabotinsky self-oscillating hydrogels under cyclic mechanical compressions. 131 time-lapse series are included here that were captured by a USB microscope camera, in order to observe the time-dependent colour and size change of BZ hydrogels, while they were subjected to regular mechanical stimuli, i.e. cyclic compressions at various frequencies. Gel pieces of various sizes and geometries were tested in different catalyst-free BZ solutions, e.g. by changing the reactant concentrations, introducing additional salts, etc
Datasets and R Code supporting results from 'New Citizen Science initiative reveals impact of climate on fruit tree blossom patterns in Great Britain'
No full textThis dataset contains gridded temperature data for Great Britain and phenological recordings for the onset of blossom for four cultivars of fruit tree (Apple 'Bramley', Cherry 'Stella', Pear 'Conference', Plum 'Victoria'). Gridded temperature data was derived from the E-Obs database (https://cds.climate.copernicus.eu/cdsapp#!/dataset/insitu-gridded-observations-europe?tab=overview) and Phenology recordings were submitted to the FruitWatch project (www.fruitwatch.org) - Contact Chris Wyver ([email protected]) for access to the full dataset, containing more cultivars and data for other years
Weather and grower dataset
No full textThis dataset supports the PhD thesis 'Epidemiology and community analysis of stem end rot-associated fungal pathogens and their impact on postharvest disease of commercial avocado (Persea americana)'. It contains commercial quality control records indicating periods of high and low stem end rot incidence as recorded by the Greencell avocado distribution centre, matched with historic weather data recorded by Visual Crossing weather data services
One-to-one Chromebook technology and student engagement in the independent secondary school classroom: a case study
Get PDFThis data was collected from an independent, co-educational secondary school in the United Kingdom, for children aged 11 to 18 years old. The aim was to understand student and teacher perceptions of one-to-one Chromebook use, not in the initial stages of a Chromebook initiative, but when the Chromebooks had been used in this case study school for over four years. Data was collected in two stages. The first stage involved the collection of survey data. Students and teachers were invited by the Head teacher to complete the survey and 168 students, and 43 teachers completed this in full. The survey was shared and completed online using Google Forms. The survey collected demographic data about students and teachers as well as asking questions connected to the construct of engagement with Chromebook technology, which revealed the perceptions of both students and teachers. The data generated is both qualitative and quantitative in nature. The initial analysis of the survey data informed stage two of the research which involved four focus group meetings with students from the school, involving two groups of three and two groups of two students (n=10) and four semi-structured interviews with teachers from the same school (n=4). The focus groups and interviews probed for more detail on the key issues that had been raised by the survey data. The focus groups and interviews were audio-recorded and then transcribed before being analysed using Nvivo12. The data in its whole reveals an insight into the perceptions of both students and teachers for comparison, to understand if both groups view student engagement in the same way
Dataset for 'Electrical measurements during fog in the United Arab Emirates'
No full textThis dataset contains potential gradient and visibility data used in the paper 'Electrical measurements during fog in the United Arab Emirates' by Alkamali, A., Ambaum, M.H.P., Nicoll, K.A. The measurements were obtained at Sanad Academy, Dubai, United Arab Emirates (UAE) (24°56' N, 55°30' E) in the year 2021; and from Reading University Atmospheric Observatory (RUAO), UK in the year 2020-21 (December-January). The data has been used within this paper to study and compare the electrical properties of fog in the UAE and the UK
Decision-making in intensive care: the role of relatives
Get PDFA pilot project with responses to an anonymous questionnaires by relatives of patients in intensive care units at Southampton General Hospital on their perception and understanding of their role in decision-making for the patient, and identifying what the patient’s wishes were. Questionnaires administered and returned in hard copy at the hospital. A selection of semi-structured and open questions
Lerwick Observatory monthly mean Potential Gradient 1925-1984
Get PDFMeasurements of atmospheric electricity, specifically the Potential Gradient (PG), are relatively rare but have occasionally been made at some sites, such as meteorological or geomagnetic observatories. A valuable series of measurements were made in the UK at Lerwick Observatory, Shetland, between 1925 and 1984. In this archive, mean monthly values of the Lerwick PG derived from the hourly measurements during this period are made available digitally
