Aprovechamiento integrado de energía solar para calefacción de ambientes, agua caliente y cocción comunitaria en el altiplano argentino

Se describe la tecnología utilizada para calefacción y calentamiento solar de agua para edificios públicos, desarrollados en dos pueblos de la puna argentina. Los sistemas instalados consisten en un colector solar de aire, un almacén térmico de piedras y un intercambiador de calor para el uso doméstico de agua caliente. Además se presentan las características de un reflector concentrador con foco fijo tipo Scheffler, destinado a cocinas comunitariasThe technology for solar heating of public buildings in two villages in the Argentine Puna region is described. The system consists of a solar air heater, a pebble bed storage and a heat exchanger for domestic hot water use. Further on a concentrating solar reflector with fixed focus is used for the community-cooker (Scheffler reflector).Asociación Argentina de Energías Renovables y Medio Ambiente (ASADES

Rußlands Perspektiven: kritische Faktoren und mögliche Entwicklungen bis 2010

'Rußland hat erhebliche Probleme, den Erwartungen seiner Partner als berechenbarer Akteur in den internationalen Beziehungen zu entsprechen. Die Transformation ist auf halbem Wege steckengeblieben, die finanzielle Basis für eine strukturelle Erneuerung ist drastisch geschrumpft. Der inzwischen eingetretene Kontrollverlust der Verantwortlichen ist besorgniserregend. Nationalistische Kräfte in Rußland denunzieren den Verfall der russischen Wirtschaft als Ergebnis einer Diskriminierungs-, ja Zersetzungspolitik des Westens. Auf der anderen Seite haben Geldgeber und Öffentlichkeit im Westen kein Verständnis mehr für Forderungen der Regierung in Moskau, ihr immer aufs neue durch finanzielle Stützungsaktionen entgegenzukommen. Die russische Politik hat sich in eine prekäre wirtschaftliche Abhängigkeit von westlicher Kooperation manövriert, die auch dem Westen wenig politischen Spielraum läßt. Die Erfahrung der letzten Jahre zeigt indes, daß Appelle von außen zur Behebung dieser Probleme solange ins Leere gehen, wie es den in demokratischen Wahlen legitimierten Eliten an Verantwortungsbewußtsein und Konsensfähigkeit fehlt.' (Textauszug)'Russia is having major problems fulfilling the expectations of its partners with regard to becoming a predictable actor in international relations. The transformation process has come to a standstill and the financial basis for structural renewal has shrunk drastically. The loss, of control of those in positions of responsibility is worrying. Nationalist forces in Russia are blaming the collapse of the Russian economy on a discriminatory or even subversive policy on the part of the West. At the same time, financiers and the Western public have run out of patience with the Russian government's continual demands for the West to keep propping it up with new financial aid packages. Russian politicians have manoeuvred themselves into a position of precarious economic dependence on Western co-operation, which has the effect of limiting the West's political options as well. The experience of the past few years has shown, moreover, that appeals from outside to resolve these problems will go on falling on deaf ears as long as the democratically elected, and therefore legitimate, elite falls to show a sense of responsibility and consensus-achieving ability.'

Terms of debate: consensus definitions to guide the scientific discourse on visual distraction

Hypothesis-driven research rests on clearly articulated scientific theories. The building blocks for communicating these theories are scientific terms. Obviously, communication – and thus, scientific progress – is hampered if the meaning of these terms varies idiosyncratically across (sub)fields and even across individual researchers within the same subfield. We have formed an international group of experts representing various theoretical stances with the goal to homogenize the use of the terms that are most relevant to fundamental research on visual distraction in visual search. Our discussions revealed striking heterogeneity and we had to invest much time and effort to increase our mutual understanding of each other’s use of central terms, which turned out to be strongly related to our respective theoretical positions. We present the outcomes of these discussions in a glossary and provide some context in several essays. Specifically, we explicate how central terms are used in the distraction literature and consensually sharpen their definitions in order to enable communication across theoretical standpoints. Where applicable, we also explain how the respective constructs can be measured. We believe that this novel type of adversarial collaboration can serve as a model for other fields of psychological research that strive to build a solid groundwork for theorizing and communicating by establishing a common language. For the field of visual distraction, the present paper should facilitate communication across theoretical standpoints and may serve as an introduction and reference text for newcomers

The P3^3 Experiment: A Positron Source Demonstrator for Future Lepton Colliders

The PSI Positron Production (P$^3$ or P-cubed) experiment is a demonstrator for a e+ source and capture system with potential to improve the state-of-the-art e+ yield by an order of magnitude. The experiment is driven by the FCC-ee injector study and will be hosted in the SwissFEL facility at the Paul Scherrer Institute in Switzerland. This paper is an overview of the P$^3$ design at an advanced stage, with a particular emphasis on a novel e+ capture system and its associated beam dynamics. Additionally, a concept for the experiment diagnostics is presented, as well as the key points of the ongoing installation works

Updated European Heart Rhythm Association practical guide on the use of non-vitamin-K antagonist anticoagulants in patients with non-valvular atrial fibrillation: Executive summary

In 2013, the European Heart Rhythm Association (EHRA) published a Practical Guide on the use of non-VKA oral anticoagulants (NOACs) in patients with atrial fibrillation (AF) (Heidbuchel H, Verhamme P, Alings M, Antz M, Hacke W, Oldgren J, Sinnaeve P, Camm AJ, Kirchhof P, European Heart Rhythm A. European Heart Rhythm Association Practical Guide on the use of new oral anticoagulants in patients with non-valvular atrial fibrillation. Europace 2013;15:625-651; Heidbuchel H, Verhamme P, Alings M, Antz M, Hacke W, Oldgren J, Sinnaeve P, Camm AJ, Kirchhof P. EHRA practical guide on the use of new oral anticoagulants in patients with non-valvular atrial fibrillation: executive summary. Eur Heart J 2013;34:2094-2106). The document received widespread interest, not only from cardiologists but also from neurologists, geriatricians, and general practitioners, as became evident from the distribution of > 350 000 copies of its pocket version (the EHRA Key Message Booklet) world-wide. Since 2013, numerous new studies have appeared on different aspects of NOAC therapy in AF patients. Therefore, EHRA updated the Practical Guide, including new information but also providing balanced guiding in the many areas where prospective data are still lacking. The outline of the original guide that addressed 15 clinical scenarios has been preserved, but all chapters have been rewritten. Main changes in the Update comprise a discussion on the definition of 'non-valvular AF' and eligibility for NOAC therapy, inclusion of finalized information on the recently approved edoxaban, tailored dosing information dependent on concomitant drugs, and/or clinical characteristics, an expanded chapter on neurologic scenarios (ischaemic stroke or intracranial haemorrhage under NOAC), an updated anticoagulation card and more specifics on start-up and follow-up issues. There are also many new flow charts, like on appropriate switching between anticoagulants (VKA to NOAC or vice versa), default scenarios for acute management of coronary interventions, step-down schemes for longterm combined antiplatelet-anticoagulant management in coronary heart disease, management of bleeding, and cardioversion under NOAC therapy. The Updated Guide is available in full in EP Europace (Heidbuchel H, Verhamme P, Alings M, Antz M, Diener HC, HackeW, Oldgren J, Sinnaeve P, Camm AJ, Kirchhof P, Advisors.
