Amount and distribution of fume contaminants in the lungs of an arc welder post mortem.
This study describes various post-mortem examinations of the lungs of a shipyard arc welder. These investigations comprised morphological methods, including gross pathology and radiography, histological and ultrastructural examinations, chemical analysis of lung tissue, and sensitive magnetic measurements, which can now be used to detect magnetic contaminants, such as welding fume, in human tissue. Such methods can also show the distribution of contaminants. The amount of welding-fume contaminants was low, only 110 mg. The contaminant iron seemed to represent only 10% of the total iron chemically analysed in lung tissue. The concentration of the total iron was 4-10 times higher than that in control tissue. Contaminants tended to collect in the central areas of the lungs. Two concentration centres could be observed in each lung, one anterior and one posterior. There was slight fibrosis around pigmented areas. Histological findings were similar to those of previous studies. Transmission electron micrographs showed that enlarged lysosomes of macrophages contained electron-dense granules, 450 nm to less than 5 nm in diameter, which formed aggregates and short chains, and resembled welding-fume particles in the breathing zone. Our results show the value of studying the same material by a number of inter-related methods

Open Innovation and Co-creation in the Public Sector: Understanding the Role of Intermediaries
Part 4: Critical ReflectionsInternational audienceInnovation is a recurring theme in public administration. Governments around the world are always exploring innovation alternatives. However, the way public organizations innovate has evolved in the last few years from “in-house” innovation to open innovation. Although the literature is rich in references to innovation in the private sector, how open innovation processes can become a true and effective tool for governments is still an underexplored topic. The few studies that have tackled it have mainly addressed one main question: how can a successful private sector practice be introduced in public sector organizations? In contrast, this paper aims at making a contribution to the existing literature on open innovation in the public sector by addressing one issue that is key in open innovation processes: the role of intermediaries. Intermediaries are important actors in the open innovation ecosystem as they facilitate activities in all stages of the innovation process and help government agencies to achieve their goals
Generating Value from Government Data Using AI: An Exploratory Study
Open government data initiatives have gained popularity around the world. Artificial Intelligence (AI) has the potential to make better use of data. Combining the OGD and AI is crucial to generate more value from data. In this paper we investigate what kind of value was generated through AI and how. A context-input-process-output/outcome (CIPO) framework is developed to describe and compare three cases. The overview of cases shows the huge potential of AI, but it also suggests that AI is hardly used by the public to create value from open data. The objectives of the three cases are efficiency, innovation and crime prevention, whereas common open government objectives like transparency, accountability and participation are given less attention. By using AI, the risks of data privacy and arriving at biased or wrong conclusions become more prominent. With the rise of data collection from Internet of Things, complying with the 5-stars of Berners-Lee becomes more important. We recommend policy makers to stimulate AI projects contributing to the open government goals and ensure that open data meets the 5-star requirements.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Information and Communication Technolog
