Brain data:Scanning, scraping and sculpting the plastic learning brain through neurotechnology

Neurotechnology is an advancing field of research and development with significant implications for education. As 'postdigital' hybrids of biological and informational codes, novel neurotechnologies combine neuroscience insights into the human brain with advanced technical development in brain imaging, brain-computer interfaces, neurofeedback platforms, brain stimulation and other neuroenhancement applications. Merging neurobiological knowledge about human life with computational technologies, neurotechnology exemplifies how postdigital science will play a significant role in societies and education in decades to come. As neurotechnology developments are being extended to education, they present potential for businesses and governments to enact new techniques of 'neurogovernance' by 'scanning' the brain, 'scraping' it for data and then 'sculpting' the brain toward particular capacities. The aim of this article is to critically review neurotechnology developments and implications for education. It examines the purposes to which neurotechnology development is being put in education, interrogating the commercial and governmental objectives associated with it and the neuroscientific concepts and expertise that underpin it. Finally, the article raises significant ethical and governance issues related to neurotechnology development and postdigital science that require concerted attention from education researchers

Candida glabrata : a review of its features and resistance

Candida species belong to the normal microbiota of the oral cavity and gastrointestinal and vaginal tracts, and are responsible for several clinical manifestations, from mucocutaneous overgrowth to bloodstream infections. Once believed to be non-pathogenic, Candida glabrata was rapidly blamable for many human diseases. Year after year, these pathological circumstances are more recurrent and problematic to treat, especially when patients reveal any level of immunosuppression. These difficulties arise from the capacity of C. glabrata to form biofilms and also from its high resistance to traditional antifungal therapies. Thus, this review intends to present an excerpt of the biology, epidemiology, and pathology of C. glabrata, and detail an approach to its resistance mechanisms based on studies carried out up to the present.The authors are grateful to strategic project PTDC/SAU-MIC/119069/2010 for the financial support to the research center and for Celia F.

A calibration facility for automatic weather stations

Environmental monitoring by automatic weather stations (AWSs) is growing as a result of the increasing number and reliability of surface observations. In order to ensure data traceability and obtain more comprehensive data on the performance of AWSs, a new transportable calibration facility was manufactured at the Italian Institute of Metrology (INRiM) in the framework of the project MeteoMet. The facility is equipped with temperature and pressure reference sensors directly traceable to the International System of Units (SI) to obtain meteorological data with well-documented calibration uncertainty. In this calibration system, temperature and pressure can be controlled simultaneously and independently so that all combinations over the ranges are possible. The nominal ranges are: absolute pressure 50 to 110 kPa and temperature -25 to 50 degrees C. The availability of a large range of atmospheric variability and the possibility of studying the mutual influence effects on sensors response are important characteristics of the facility. This apparatus is also designed to permit a control in humidity, in order to complete the characterization of the whole AWS pressure-temperature-humidity modulus. As a matter of fact, the final version of the facility will be equipped with a humidity generator for hygrometer calibrations. Finally, the calibration system is designed to be transportable, therefore allowing the calibration of AWSs located at sites that are difficult to access such as Ny-angstrom lesund (Svalbard) stations, where the facility was employed. The design and the technical characteristics are reported in this paper

Design of a joint research data platform: A use case for severity assessment

Severity assessment in animal models is a data-driven process. We therefore present a use case for building a repository for interlaboratory collaboration with the potential of uploading specific content, making group announcements and internal prepublication discussions. We clearly show that it is possible to offer such a structure with minimal effort and a basic understanding of web-based services, also taking into account the human factor in individual data collection. The FOR2591 Online Repository serves as a blueprint for other groups, so that one day not only will data sharing among consortium members be improved but the transition from the private to the persistent domain will also be easier

WEEE treatment in developing countries: environmental pollution and health consequences - an overview

In the last few decades, the rapid technological evolution has led to a growing generation of waste electrical and electronic equipment (WEEE). Not rarely, it has been exported from industrialized to developing countries, where it represents a secondary source of valuable materials such as gold, copper, and silver. The recycling of WEEE is often carried out without any environmental and health protection. This paper reviews recent literature dealing with the informal treatment of WEEE in developing regions, gathering and analyzing data on concentration of both inorganic and organic pollutants in the environment. Open burning practices are revealed as most polluting ‘technology’, followed by mechanical treatment and leaching. Significant levels of pollutants have been detected in human bodies, both children and adults, working in or living in areas with informal WEEE treatment

Optimized industrial sorting of WEEE plastics: Development of fast and robust h-XRF technique for hazardous components

Waste electrical and electronic equipment (WEEE) are a source of both hazardous and valuable materials that must be segregated for treatment. Previous studies addressing the use of handheld X-Ray fluorescence (h-XRF) as a sorting tool for WEEE plastics through the identification of hazardous components include plastics from mixed WEEE streams, processed material (shredded or treated plastics) and low number of samples not allowing to consider their findings for application on an industrial scale. Thus, further research is needed to establish scalable robust methods for sorting this material. We describe a study carried out on whole flat panel display equipment (FPD) plastic casings using h-XRF for the detection of total bromine (Br) and antimony (Sb) as tracers for Brominated Flame Retardants (BFRs) and Sb2O3 additives. The aim being to characterize the targeted material and to define the optimal analysis conditions to meet large scale throughputs. A ring trial exercise comprising 100 samples was conducted to evaluate the validity of the measurements. Results indicate that: 1) the use of h-XRF under the conditions determined in this study offers a valid technique to screen total Br and Sb in whole FPD casings at industrial scale with low uncertainty, 2) Br and Sb are found to be homogeneously distributed within the casing, 3) an optimal h-XRF analysis time of 10 seconds is suitable from both accuracy and practical implementation for LOD<[Br]≤ 830 mg kg−1 and LOD<[Sb]≤8400 mg kg−1, and 4) the presence of dust deposited on the casings was excluded as a factor affecting h-XRF results. To our knowledge this is the first evaluation of optimal sorting conditions for whole display casings using h-XRF, within a manual dismantling process
