Ecodesign and Energy Label for Household Dishwashers

European Commission launched in 2014 the revision of the ecodesign and energy-/resource label implementing measures for the product group 'household dishwashers (DW)'. The revision study follows the Commission’s Methodology for the Evaluation of Energy related Products (MEErP) and includes sections related to the scope and definition market analysis, analysis of user behaviour and system aspects, analysis of technologies, environmental and economics, design options and policy analysis and scenarios.This research was based on available scientific information and data, uses a life-cycle thinking approach, and has engaged stakeholder experts in order to discuss key issues, and to the extent possible reach consensus on the proposals The outcomes of this study provides policy makers with the evidence basis for assessing whether and how to revise the existing Regulations.JRC.B.5-Circular Economy and Industrial Leadershi

Ecodesign and Energy Label for Household Washing machines and washer dryers

The European Commission launched in 2014 the revision of the ecodesign and energy-/resource label implementing measures for the product group 'household washing machines and household washer dryers (WM-WD)'. The revision study follows the Commission’s Methodology for the Evaluation of Energy related Products (MEErP) consisting of: Scope definition, standard methods and legislation, Market analysis, Analysis of user behaviour and system aspects, Analysis of technologies, Environmental and economics, Design options and Policy analysis and scenarios The comprehensive analysis of the product group following the steps above will feed as research evidence basis into the revision of the existing Energy Label Regulation (EC) 1060/2010 and the Ecodesign Regulation (EC) 1015/2010 on household washing machines. The research is based on available scientific information and data, uses a life-cycle thinking approach, and has engaged stakeholder experts in order to discuss key issues, and to the extent possible reach consensus on the proposals.JRC.B.5-Circular Economy and Industrial Leadershi

Proceedings of the Nimbus Program Review

The Nimbus program review was conducted at the George Washington Motor Lodge and at General Electric Missiles and Space Division, Valley Forge, Pennsylvania, on November 14, 15, and 16, 1962. The purpose of the review was twofold: first, to present to top management of the Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Headquarters, other NASA elements, Joint Meteorological Satellite Advisory Committee (_MSAC), Weather Bureau, subsystem contractors, and others, a clear picture of the Nimbus program, its organization, its past accomplishments, current status, and remaining work, emphasizing the continuing need and opportunity for major contributions by the industrial community; second, to bring together project and contractor technical personnel responsible for the planning, execution, and support of the integration and test of the spacecraft to be initiated at General Electric shortly. This book is a compilation of the papers presented during the review and also contains a list of those attending

The impact of teacher and peer dialogue on online collaborative writing in an authentic science literacy learning environment

This research is concerned with authentic science writing, and in particular, investigating collaborative science writing at secondary school level, using an online collaborative-writing environment. Specifically, it investigates how measures of successful authenticity relate to (i) how close to the text-structure of a prototypical library report genre are collaboratively-written student papers (i.e., how close to the model students were taught) (ii) to what extent do the papers use the language of science as expected at this level of schooling, for example, use of nominalization, and finally, (iii) what is the degree of participation and contribution by students in a collaborative writing task? The research also examined how students' collaboratively written texts evolved, or changed, over time in terms of their textual structure and of their key linguistic features. The research provides some insight into how text changes and evolution could be explained in relation to online dialogue and feedback. Finally, the thesis identifies the implications of the above for pedagogy and policy, i.e., for (i) students' language development in science and the use of genre pedagogies, (ii) collaborative writing in science, and (iii) on line pedagogy

The Cryogenic Pumping Section of the KATRIN Experiment - Design Studies and Experiments for the Commissioning

The aim of the Karlsruhe Tritium Neutrino (KATRIN) experiment is the determination of the neutrino mass with a sensitivity of 200 meV/c2 (90 %C.L.), by high precision tritium beta spectroscopy. The experimental setup requires ultra-high vacuum conditions. This thesis investigates the pumping properties of one of the key components namely the cryogenic pumping section. It focuses on the pumping with argon frost, the preparation of an active argon frost layer, as well as on NEG pumping

Lithics in the land of the lightning brothers

Lithics in the Land of the Lightning Brothers skilfully integrates a wide range of data-raw-material procurement, tool design, reduction and curation, patterns of distribution and association-to reveal the major outlines of Wardaman prehistory. At the same time, the book firmly situates data and methods in broad theoretical context. In its regional scope and thorough technological approach, this book exemplifies the best of recent lithic analysis and hunter-gatherer archaeology. Any archaeologist who confronts the challenge of classifying retouched stone tools should consult this volume for a clear demonstration of reduction intensity as a source of size and form variation independent of “type.” Yet the demonstration is not merely methodological; Clarkson shows how the measurement of reduction intensity informs analysis of technological diversity and other cultural practices. In Clarkson’s hands, Wardaman prehistory emerges as a particular record of the human past. Yet the book is also a case study in prolonged cultural response to environmental conditions and the way in which cultures persist and reproduce themselves over long spans of time. The result is an analytical tour de force that will guide hunter-gatherer archaeology in Australia and elsewhere for years to come
