Assessing impacts of Common Agricultural Policy changes on regional use patterns with a decision support system. An application in Southern Portugal

This paper discusses research aiming at assessing Common Agricultural Policy impacts on agriculture and forestry. For this purpose an approach is developed that includes a linear programming model to estimate the Positive Mathematical Programming production cost function coefficients of current agricultural– forestry activities. It further includes a heuristic — simulated annealing — to generate solutions for each policy scenario. This model base approach is integrated within a decision support system (DSS) for testing purposes. The DSS further encompasses a relational database that stores agricultural–forestry technical and economic data and a geographic information system that stores topological data of regional farm-type land units. The DSS Graphical User Interface provides tabular and geographical reporting capabilities. Results are discussed for an application to the Alentejo region in Southern Portugal. Results demonstrate the usefulness and relevance of the proposed approach to assess the impact of changes in prices and in agricultural policy on land use patterns and on forestr

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

AFM Observations of Latent Fission Tracks on Surfaces: Amorphous SiO 2 and Quartz

Preliminary results of a systematic AFM experimental investigation of the surface 'track' effects produced by the passage of fission fragments from a californium (252Cf) source into amorphous SiO2 and quartz are described. Fission fragments from the source were collimated using a 10 μm thick aluminum foil and comprised fragments with the usual binary distribution of energies - light and heavy - 79.4 and 103.8 MeV. Irradiations and AFM measurements were carried out in air at normal room temperature and pressure. Remarkably high sputtering yields/fragment were discovered, and in the case of crystalline quartz the ejecta was found to be arranged in an ordered manner. A brief discussion is given of a part likely to be played by electronic energy loss induced Coulomb explosion of target atoms for each point of fragment entry

Tobacco Smoke Occupational Exposure: Biomarkers of Biological Damage

Work perfomed by Instituto Nacional Saúde Doutor Ricardo Jorge, Laboratório de Análises de Dopagem, Instituto do Desporto de Portugal, Clínica Universitária Pneumologia, Faculdade Medicina Lisboa, Hospital Santa MariaHigh concentration of toxic substances emanated from tobacco smoke in entertainment places such as restaurants, bars and nightclubs may compromise indoor air quality (IAQ) generating environments of likelihood health risk. Their employees, particularly those exposed to second-hand smoke, are at increased risk for developing chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD), asthma and lung cancer. Objectives In this work, we aimed at evaluating relationships between occupational ETS exposure, biological damage (DNA or proteome alterations) and putative respiratory dysfunctions. Materials and Methods A group of restaurants located in Lisbon has been studied, in which fine particles (smaller than 2.5µm; PM2.5), indicative of environmental tobacco smoke (ETS) contamination, were measured. After informed consent, workers were evaluated for acute exposure to ETS based on cotinine levels in urine and clinically evaluated for their respiratory health by spirometry measurements and chestpiece auscultation. Effects of ETS exposure on genotoxic lesions were evaluated by measuring DNA/chromosomes breaks in peripheral blood lymphocytes and buccal mucosa cells. Effects of ETS exposure on plasma proteins is being studied using a 2D-DIGE-MALDI-TOF/TOF approach. To achieve that goal, global proteome characterization is being carried based on the same individual plasma samples collected for genotoxic studies and were pooled according to previous criteria. Results Results have confirmed higher respirable particle levels in smoking-designated areas of those entertainment places, indicating an ETS contamination. Leukocytes from ETS-exposed-workers presented lower levels of genotoxic-induced damage in comparison with non-exposed workers, suggesting an ETS-induced stress adaption response in exposed-workers. By proteomics, we are now to investigating those workers for putative alterations on their plasma proteome to provide additional insights on the adaptative response mechanisms that might be activated by ETS exposition. Conclusion Altogether, this study provides information on indoor air quality of Lisbon smoking entertainment places, in particular ETS contamination, and may provide biomarker candidates for occupational ETS-exposure which might precede respiratory diseases on their employees.Work supported by Fundação Calouste Gulbenkian, Administração Central do Sistema de Saúde, FCT/PolyAnnual Funding Program and FEDER/SaudeXXI Program, Portugal.
