Flower visitor, fruit yield and fruit quality data from UK apple orchards under flowering and nesting habitat interventions
Get PDFThese data include information on flower visitors, fruit set and fruit quality (size, weight and seed number) of apples grown under different pollination treatments including pollinator exclusion (no visitation by insects), open pollination (visitation by insects) and supplementary pollination (hand pollinated) in orchards receiving combinations of nesting floral habitat interventions. Data were collected for the Sustainable Pollination Services for UK crops project
Dynamics of cyprodinil and fludioxonil in sunflower (Helianthus annuus L.)
No full textThe aim of the study was to investigate the pesticide residue profiles of the two active ingredients fludioxonil and cyprodinil in different sunflower matrices including pollen and nectar.
Therefore, sunflower plants were sprayed during flowering and at different developmental stages to assess the influence of time on residue expression.
Extrafloral nectar, pollen, anther, florets and leaf samples were taken daily over the course of 1-2 weeks. Samples were analysed for residues of both active ingredients using LC-MS/MS
Material specific dataset covering information for decorated Iron Age artefacts
No full textThis dataset includes recorded information for five material types: ceramic pottery, antler/bone combs, stone, wood, and metal. This information has been accumulated into four Access databases [Pottery, Antler/Bone, Stone/Wood, and Metal]. Stone and Wood have been combined into one database for recording due to the number of examples compared to the other material sources. All four of these databases include information covering General Information [site name, type of site, county, regional zone, period of occupation], Context [previous artefact number, location on site, date of object], Material [general material, form type, inclusions, colour, condition], Decoration [general typology, location on object, direction on decoration, general decoration, motifs], Decorative Techniques, and Reference Information. This information was collected from object descriptions and illustrations within site reports and previous literature. In order to avoid any overlap, all of the artefacts were re-labelled based on the material and order in which they have been recorded within my database. My final database includes a Reference Database. This database includes a list of all materials covered within my previous Access databases, their current artefact numbers, and a citation of their original sources.
This dataset was created to determine the visual qualities of different artefacts based on their material associations; their similarities, differences, and connections to form, function, and decoration. In turn, these databases were used within my PhD thesis to highlight the potential social connections between different groups and regions within southern Britain during the Iron Age

The tracking has been performed with the TRACK algorithm and the identification scheme is based on previous studies. Please read the README file for more information.
These datasets support the publication: Bresson, H., K. I. Hodges, L. C. Shaffrey, G. Zappa, R. Schiemann, 2022, JGR Atmospheres: The response of Northern Hemisphere polar lows to climate change in a 25 km high-resolution global climate model. https://doi.org/10.1029/2021JD03561
Data supporting 'The value of donkeys to livelihood provision in northern Ghana'
Get PDFThe research was undertaken to investigate the value of donkeys to various stakeholders in northern Ghana.
This dataset consists of four parts. The first part, a folder entitled '1_Data.zip' contains eight separate zipped datafiles. These comprise the original, anonymised research data collected with both donkey and non-donkey owners in northern Ghana on their perceptions of the value of their donkeys to their livelihood provision. Relevant data underpinning seven specific charts and tables in the paper currently under review include why people keep donkeys and barriers to owning them; the frequencies of certain activities undertaken with donkeys across the year; the reasons why non-donkey owners would like to own donkeys; temporal and contemporary costs of purchase of donkeys and, in three different scenarios, which animal would participants sell first to meet unexpected costs of living.
The second part, a folder entitled '2_FAO_Livestock_Data.zip' contains one file of the temporal and current numbers of live asses in Ghana and Burkina Faso recorded by the Food and Agriculture Organisation (FAO) and downloaded from their website (https://www.fao.org/faostat/en/#home and https://www.fao.org/faostat/en/#data/QCL).
The third part, a folder entitled '3_Documentation.zip' provides the documentation that enabled the research study to take place in two further zipped files: Methodology and Research Instruments.
The fourth part, a restricted folder entitled '4_Consent Forms.zip' provides nine consent forms for the research instruments held with various participants in the study
Dataset supporting paper 'Circulating extracellular vesicles are strongly associated with cardiovascular risk markers'
Get PDFThis dataset includes all reports and summaries of raw data supporting the results presented in the paper �Circulating extracellular vesicles are strongly associated with cardiovascular risk markers'. The objective of this paper is to investigate the relationships between circulating extracellular vesicles (EVs), conventional cardiovascular risk markers and thrombogenic markers in subjects with moderate risk of cardiovascular diseases (CVDs), which is the part aim of a larger study investigating the effect of fish oil-derived n-3 polyunsaturated fatty acids on the generation and functional activities of EVs based on a randomised, double-blind, placebo-controlled crossover intervention. The results and findings involved in this dataset relate only to the baseline data prior to any intervention. A total of 40 subjects (aged 40~70yrs) with moderate risk of CVDs were recruited and involved in the study. Approximately 100ml of blood was collected from individuals after overnight fasting for all analysis, in which 35ml was processed for the analysis of circulating EVs, 9ml was taken for the analysis of blood lipids and glucose levels for the conventional cardiovascular markers evaluation and the rest was operated for the thrombogenic markers evaluation.
Data about EVs parameters include: i. the numbers and size of circulating total EVs measured by Nanoparticle Tracking Analysis (NTA); ii. the numbers of EV subpopulations (i.e. phosphatidylserine-positive EVs (PS+EVs), platelet-derived EVs (PDEVs) and endothelial-derived EVs (EDEVs)) measured by flow cytometry (FCM); iii. the procoagulatory activity of circulating EVs (in vitro thrombogenic potential in activating tissue factor-dependent thrombin generation) measured by thrombin generation assay. Data about conventional cardiovascular risk markers include i. body mass index (BMI) measured by Tanita; ii. blood pressure measured by upper arm blood pressure monitor; iii. plasma lipid profile (i.e. triacylglycerol (TAG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and glucose concentrations measured by iLab; iv. 10-year CVD risk detected by QRISK2 scoring system. Data about thrombogenic markers include: i. plasma platelet aggregation measured by 96-well high-throughput aggregometry; ii. plasma thrombin generation measured by thrombin generation assay; iii. plasma clot growth and fibrinolysis measured by thrombodynamics analyser

Archive of high-resolution barometric pressure records for the UK and Ireland, 15-18 January 2022
Get PDFAt 0415 UTC on 15 January 2022, the large subterranean volcano Hunga Tonga�Hunga Ha�apai in the south Pacific Ocean exploded violently. The subsequent pressure wave radiated outward from the volcano at close to the speed of sound and was detected across the entire globe, reaching the British and Irish Isles some 14 hours after the eruption.
This dataset preserves high-resolution records of barometric pressure (1 minute frequency, precision 0.1 hPa or better) from about 50 sites across the United Kingdom and Ireland used in the analysis of the multiple airwaves, and their reverberations across the globe. In all, over 160,000 records are included. The amplitude of the airwaves reaching the British Isles appears to be without precedent since the very similar events following the similarly violent eruption of Krakatoa in August 1883
