    1998-11-01

    The main objectives pursued are: (a) verify the quality of reactor pressure vessels in existing LWR-type reactors, and (b) quantify the safety margin using both specified and non-specified materials and welds. On the basis of knowledge obtained through earlier programmes, the research project was to examine in particular deviations from the specified materials properties, for more exact quantification of the safety margin before RPV failure. There are three major factors influencing the component performance until failure, which are aggregate material fatigue, flaws, loading conditions, and the research work was to focus on the materials properties. An item of main interest was to assess the impact of long service life on the materials properties, assuming particularly unfavourable boundary conditions for materials properties and operational loads. (orig./CB) [Deutsch] Die Hauptziele des Forschungsvorhabens Komponentensicherheit waren (a) die Qualitaet bestehender Reaktordruckbehaelter von Leichtwasserreaktoren zu verifizieren, und (b) den Sicherheitsabstand zu quantifizieren unter Verwendung von Werkstoffen und Schweissverbindungen, die innerhalb und ausserhalb der Spezifikation liegen. Gestuetzt auf Erkenntnisse aus frueheren Programmen sollten zur quantitativen Erfassung des Sicherheitsabstandes gegen Versagen des RDB`s insbesondere auch Abweichungen vom spezifikationsgemaessen Werkstoffzustand betrachtet werden. Von den drei Haupteinflussgroessen Werkstoffzustand, Fehlerzustand, Beanspruchungszustand, die das Versagensverhalten bestimmen, lag der Schwerpunkt des FKS auf der Untersuchung des Werkstoffeinflusses. Insbesondere sollte geprueft werden, wie sich der Langzeitbetrieb auf die Aenderung der Werkstoffeigenschaften auswirkt, wenn besonders unguenstige Randbedingungen von Werkstoffzustand und Betriebsbedingungen zugrunde gelegt werden.

    Full Text Available This position paper explores the ambiguity of technology, toward refined understanding of Educational Technology. The purpose of education is described by John Dewey as growing, or habitual learning. Two philosophical conceptions of technology are reviewed. Dewey positions inquiry as a technology that creates knowledge. Val Dusek offers a “consensus definition,” a systems approach to technology that merges into social construction theory and actor-network theory, both of which emphasize complex relations between humans and technology. Using Dewey and Dusek as reference, literature related to Educational Technology is reviewed. A history of its definitions and conceptions of hard (material technology and of soft (process technology are examined. Three brief case studies reveal a bias toward hard technology in contemporary discourse. A misconception that soft technology begins with pre-authenticated knowledge is identified and shown to obscure the reciprocity between technology and the intellect. Cet exposé de position se penche sur l’ambiguïté de la technologie en vue de raffiner la compréhension de la technologie pédagogique. L’objectif de l’éducation est décrit par John Dewey comme étant un apprentissage croissant ou habituel. Deux conceptions philosophiques de la technologie sont examinées. Dewey considère l’enquête comme une technologie qui crée le savoir. Val Dusek offre une « définition consensuelle », une approche systémique de la technologie qui rejoint la théorie de la construction sociale et la théorie de l’acteur-réseau, qui mettent toutes deux l’accent sur les relations complexes entre les humains et la technologie. Utilisant Dewey et Dusek comme référence, la documentation portant sur la technologie pédagogique est examinée.

    The VGB research project was to examine and characterize various, operation-induced impacts on the crack formation in stabilized austenitic steels, caused by intercrystalline stress corrosion cracking as a result of sensitization after chromium depletion at the grain boundaries. The results of this project as well as available operating experience show that the measures taken so far for the future operation of the German BWR plants, for avoiding in these plants intercrystalline stress corrosion cracking, correspond to the state of the art and achieve the wanted purpose. These measures are: use of optimized material W-No. 1.4550 with reduced carbon contents; use of optimized welding techniques for reducing the heat input and the welding shrinkage (cold deformation.); optimized preparation of welding work in order to avoid shape defects during welding (eg. edge misalignment, defective mash welds); reduction of tensile stresses occurring during welding; compliance with the recent VGB water chemistry code. (orig./CB) [Deutsch] Das VGB-Forschungsvorhaben sollte verschieden gelagerte Einfluesse auf die Rissbildung im Betrieb von stabilisierten austenitischen Staehlen, verursacht durch interkristalline Spannungsrisskorrosion infolge Sensbilisierung durch Chromverarmung an den Korngrenzen, systematisch erfassen. Aus den Forschungsergebnissen dieses VGB-Programms sowie den bisher vorliegenden Betriebserfahrungen ist festzuhalten, dass die bisher durchgefuehrten Massnahmen fuer den zukuenftigen Betrieb der deutschen SWR-Anlagen zur Vermeidung von interkristalliner Spannungsrisskorrosion zielgerichtet waren und dem heutigen Wissensstand entsprechen. Diese Massnahmen sind: 1. Einsatz von optimiertem Werkstoff W.-Nr. 1.4550 mit abgesenktem Kohlenstoffgehalt; 2. Einsatz von optimierten Schweissverfahren zur Verminderung der Waermeeinbringung und zur Verringerung des Schweissschrumpfes (Kaltverformung.); 3.

    This report describes the results of a qualitative study of the barriers that actors involved in the development and commercialization of polymer solar cells, may encounter. The purpose of this socio-economic research is to identify these barriers for the (market) development of thin film polymeric PV technology and to develop strategies for them in order to overcome the constraints. The necessary data are collected from interviews with actors who are active in the development and deployment of conventional solar cells. Based on the results from this study, it is conclude that it is important for the Organic PV industry to carry out many market experiments beyond the built environment. The report provides recommendations with regard to the markets in which these experiments are most likely to succeed and which drivers should be taken into account [Dutch] Dit rapport beschrijft de resultaten van een kwalitatief onderzoek naar de barrieres die actoren, betrokken bij de ontwikkeling en marktintroductie van polymere zonnecellen, kunnen tegenkomen. Het doel van dit sociaal-economische onderzoek is deze barrieres voor de (markt)ontwikkeling van dunne film polymere PV technologie te identificeren en strategieen te ontwikkelen om ze voor te zijn of ze te overbruggen. De benodigde gegevens worden verzameld uit interviews met actoren die actief zijn in de ontwikkeling en uitrol van conventionele zonnecellen. Op basis van de resultaten uit dit onderzoek komen we tot de conclusie dat het voor de Organische PV sector belangrijk is veel marktexperimenten aan te gaan buiten de gebouwde omgeving. Het rapport geeft aanbevelingen in welke soort markten deze experimenten de meeste kans van slagen hebben en met welke drivers van marktpartijen rekening moet worden gehouden.

    Health care and building services professionals are increasingly working together, even though there are apparent differences in each others approaches. This paper will zoom in on these differences. Examples from long-term care and ageing-in-place such as home automation, technology for dementia, medical equipment at home, the need for cooling during hot summers, and special lighting systems should lead to steps to bridge the gap between technology and health care. [Dutch] De zorg en de installatiewereld werken steeds nauwer met elkaar samen, zij het dat elkaars werkwijzen duidelijk verschillen. Dit artikel gaat hier dieper op in. Aan de hand van voorbeelden uit de ouderenzorg en het langer zelfstandig wonen, zoals domotica, technologie voor dementie, medische apparatuur aen huis, koeling bij hete zomers en speciale verlichting, zal worden geprobeerd de technologie dichter naar de zorg toe te laten groeien.

    Pipeline inspection pigs with individual test probes are limited in their function due to the fixed arrangement of sensors on the support. In contrast, the phased-array technology enables multitasking of tests, e.g. stress and corrosion testing which formerly required two different test runs with different sensor set-ups. The angles of inclination can be adapted to the test medium, and virtual sensors can be matched in size and overlap so that, e.g., small pittings will be detected. The sensor set-up presented here enables higher test speed and improved flaw detection. The contribution describes the measuring principle, the inspection pig (UltraScan DUO), and some results of prototype measurements. [German] Pruefmolche fuer die Pipelinepruefung mit Einzelpruefkoepfen sind in ihrem Funktionsumfang aufgrund der festliegenden Anordnung der Sensoren im Sensortraeger eingeschraenkt. Die Phased-Array-Technologie gestattet die simultane Durchfuehrung verschiedener Pruefaufgaben, wie beispielsweise der Rissund der Korrosionspruefung, die vorher zwei Prueflaeufe mit verschiedenen Sensortraegern erforderten. Die Einfallswinkel koennen auf das jeweilige Medium angepasst werden, und es besteht die Moeglichkeit, virtuelle Sensoren bezueglich ihrer Groesse und der gegenseitigen Ueberlappung so anzupassen, dass beispielsweise kleine Pittings gefunden werden koennen. Die ausgefuehrte Form gestattet hoehere Pruefgeschwindigkeit und verbesserte Fehlerauffindung. In diesem Artikel werden das Messprinzip und der Inspektionsmolch (UltraScan DUO) beschrieben sowie einige Prototyp-Messergebnisse vorgestellt.

    Lieferungen der OPEC und Russlands zu verringern. Die Kritiker betonen dagegen die mit dem Fracking verbundenen Umweltrisiken und sehen in der Ausweitung der fossilen Energiebasis ein Hemmnis fuer den klimapolitisch erforderlichen Uebergang zu erneuerbaren Energien. Der deutsche Gesetzgeber betont die mit dem Fracking verbundenen Umweltrisiken und hat mit dem Fracking-Gesetzespaket vom 24. Juni 2016 das Fracking faktisch verboten. International werden die Vor- und Nachteile des Frackings allerdings sehr unterschiedlich bewertet, so dass mit einem weiteren Ausbau der unkonventionellen Oel- und Gasfoerderung zu rechnen ist. Derzeit konzentriert sich das Fracking fast ausschliesslich auf die USA. Zahllose Studien untersuchen die Potentiale, die Wirtschaftlichkeit der verschiedenen Gewinnungsverfahren sowie die Umwelteffekte. Die amerikanische Schiefergasfoerderung bietet daher ein hervorragendes Anschauungsobjekt, um die Technologie, ihre Wirtschaftlichkeit und ihre Folgen abzuschaetzen. Das vorliegende Buch wertet die aktuellen Studien und Daten aus und leistet einen Beitrag zur Einschaetzung der laengerfristigen energiewirtschaftlichen und klimapolitischen Bedeutung der Schiefergasgewinnung im internationalen Rahmen.

    Full Text Available This paper reports on a subset of findings from a larger study investigating resistance from academic staff to the integration of technology with on-campus foreign language teaching at one North American higher education institution. The study revealed that the factors influencing technology adoption paralleled Davis’ Technology Acceptance Model’s tenets of perceived usefulness and ease of use. Further, this study supports Lai and Savage’s (2013 assertion of a lack of attention to the pedagogical affordances of technology when adoption decisions are made by instructors, thus we highlight the need for higher education leaders to determine strategies promoting awareness of the benefits technology-enabled teaching and learning can bring to advance educationally-rich flexible learning opportunities. Cet article traite d’un sous-ensemble de résultats provenant d’une étude plus vaste ayant enquêté sur la résistance des universitaires envers l’intégration de la technologie à l’enseignement en langue étrangère sur le campus dans un établissement nord-américain d’études supérieures. L’étude a révélé que les facteurs ayant une influence sur l’adoption de la technologie coïncident avec les principes du modèle d’acceptation de la technologie de Davis sur l’utilité perçue et la facilité d’utilisation. De plus, cette étude appuie l’assertion de Lai et Savage (2013 d’un manque d’attention envers les affordances pédagogiques de la technologie lorsque les décisions d’adoption sont prises par les formateurs. Nous soulignons donc le besoin, pour les meneurs de l’éducation supérieure, de déterminer les stratégies qui favorisent la connaissance des avantages de l’enseignement et de l’apprentissage que permet la technologie pour faire progresser les occasions d’apprentissage flexibles et riches sur le plan éducatif.

    Directory of Open Access Journals (Sweden)

    Stéphane Savard

    2007-09-01

    Full Text Available Ce texte met en lumière l’importance des représentations symboliques de la nature et de la technologie –véhiculées par Hydro-Québec ou par le biais de cette société d’état – au sein de la mémoire collective québécoise ou, plus précisément, des usages du passé. Utilisant le concept de lieu de mémoire et débutant l’analyse à l’aide de quatre photographies significatives de l’histoire d’Hydro-Québec et du Québec des années 1960 et 1990, l’auteur montre que les représentations mémorielles, qui font d’Hydro-Québec un lieu de mémoire en ce qui concerne les rapports à la nature et à la technologie, ont changé entre ces deux périodes. Ainsi, Hydro-Québec et ses grandes réalisations représentent au crépuscule des années 1960 la conquête du Canadien français – qui deviendra le Québécois francophone – sur la nature et l’eau enfin domestiquées. Toutefois, vers le milieu des années 1990 et à la suite des catastrophes naturelles du déluge du Saguenay et de la Crise du verglas, l’entreprise publique devient l’instrument pour promouvoir des représentations centrées sur le respect de l’environnement et du développement durable. Quant au rapport à la technologie, la société d’État symbolise lors de la Révolution tranquille le fleuron d’un Québec francophone tourné vers la technologie, émancipé de son statut de porteur d’eau et entrant manifestement dans la « modernité »; image qui semble s’essouffler dans les années 1990 alors qu’Hydro-Québec et ses ouvrages ne sont plus perçus comme étant à la fine pointe de la technologie.

    Full Text Available Backchannel technology can be used to allow students in large lecture courses to communicate with each other and the instructor during the delivery of lecture content and class discussions. It can also be utilized by instructors to capture, summarize, and integrate student questions, ideas, and needs into course content both immediately and throughout the course. The authors integrated backchannel software in one of two sections of a course, leaving the other section as a control; combined, the two sections contained a total number of 871 students. Data was gathered comparing both groups using online surveys and semester grades; results showed that the section using backchannel software had higher class satisfaction and perception of engagement, used their mobile devices more for accessing class content, felt more comfortable participating in class discussions, and had a higher grade average than the section that did not. The authors also explore their own experiences of finding, integrating, and maintaining backchannel technology. La technologie d’arrière-plan peut permettre aux étudiants de grands cours magistraux de communiquer les uns avec les autres et avec l’instructeur durant le cours et les discussions en classe. Les instructeurs peuvent aussi l’utiliser pour saisir, résumer et intégrer les questions, idées et besoins des étudiants dans le contenu du cours, et ce, immédiatement et pendant toute la durée du cours. Les auteurs ont intégré un logiciel d’arrière-plan dans l’une des deux sections d’un cours, faisant de l’autre section son groupe témoin. Ensemble, les deux sections comprenaient 871 étudiants. Des données ont été recueillies pour comparer les deux groupes à l’aide de sondages en ligne et des notes du trimestre. Les résultats ont démontré que la section utilisant le logiciel d’arrière-plan avait une plus grande satisfaction et une meilleure perception de l’engagement, que ses

    Full Text Available The purpose of the Technology and High School Success (THSS initiative was to encourage innovative strategies focused on improving provincial high school completion rates, using technology and student-centered learning to engage student interest. The primary purpose of this paper is to report on barriers that impede systemic, effective and sustainable technology integration within schools. Even with teacher and administrative support and commitment for THSS, evaluative research indicated minimal change in system capacity as a result of the initiative. Three primary barriers to program sustainability were: 1 schools and school districts did not leverage the opportunity to revisit their existing vision(s, 2 schools and school districts did not use data to make changes, and 3 limited access to technology. Le but de l’initiative « Technology and High School Success (THSS » était d'encourager des stratégies novatrices visant à améliorer le taux d’achèvement des études secondaires dans la province de l’Alberta en utilisant la technologie et un apprentissage centré sur l'élève afin de susciter l'intérêt des élèves. L'objectif principal de cet article est de rendre compte des obstacles entravant l'intégration systémique, efficace et durable de la technologie dans les écoles. La recherche évaluative a révélé des changements minimes dans la capacité systémique à la suite de l'initiative, et ce, malgré l’appui et l’engagement des enseignants et des administrateurs envers le THSS. Les trois obstacles principaux à la viabilité du programme sont les suivants: 1 les écoles et les districts scolaires n'ont pas profité de l’occasion pour revoir leur(s vision(s, 2 les écoles et les districts scolaires n'ont pas utilisé les données pour effectuer des changements, et 3 l'accès limité à la technologie.

    L'Homme a su coller avant de savoir écrire et compter. Le collage est en effet l'une des premières techniques d'assemblage d'une structure que l'homme ait utilisée, technique qui n'est devenue science qu'au début du 20e siècle avec la fabrication des premières colles synthétiques. Cette science de l'adhésion a considérablement progressé ces dix dernières années et ce livre présente l'état actuel des connaissances en décrivant les progrès considérables réalisés dans la compréhension des phénomènes fondamentaux qui font qu'un collage tient bien et durablement. Après l'exposé des bases scientifiques nécessaires et des modèles théoriques récents, l'auteur introduit la distinction entre collages faibles et collages forts puis expose les difficultés rencontrées dans les cas pratiques, difficultés souvent dues à la complexité de la chimie des surfaces et des réactions surface-polymère. L'ouvrage se termine par la présentation de quelques applications récentes, en particulier dans...

    In a first part, after a brief recall concerning 'planar' technology we discuss the various parasitic elements associated with integrated circuits components. Mathematical formulae of these elements are derived. In a second part, we present a matrix of 22 transistors and 12 resistors which has been realized. This matrix enables the integration of the major part of nuclear circuits. Some of the obtained circuits are shown, particularly an emitter coupled logic gate which presents good electrical behaviour.

Un developpement sommaire des expressions mathematiques de ces elements est propose. Dans une seconde partie nous presentons la matrice de 22 transistors et 12 resistances que nous avons realisee. Cette matrice repond aux principaux besoins de l'electronique nucleaire. Nous proposons ensuite quelques exemples de circuits realises a partir de cette matrice dont notamment une porte logique a emetteurs couples de performances tres interessantes. (auteur)

    This paper is intended to contribute to the discourse of this book both in a direct and indirect way, in so far as the paper can be searched for the aspects and insight brought in from the perspective of the humanities, and what impact these may have on innovative processes for technological progress. The author refers for instance to aspects of ethics that go beyond the existing concept of ethics of technology, and also refer to the connection between ethics and aesthetics, so as to maintain a wider view encompassing the latter aspects. (orig./CB) [German] Der folgende Beitrag will zum Gesamtthema nicht nur direkt, sondern auch indirekt etwas beitragen, sofern er daraufhin befragt werden kann, was durch eine geisteswissenschaftliche Perspektive ins Spiel kommt und was sich daraus fuer die Innovation von technologischen Entwicklungen ergeben koennte. Dabei ist generell wichtig, dass nicht nur interdisziplinaere Kooperationen (wie zwischen Techniksoziologie und Technologie) eine Rolle spielen, sondern auch das Herausarbeiten bestimmter Aufgaben, die quer zu den Faechern oder Wissenschaftszweigen verlaufen. Das betrifft beispielsweise Aspekte der Ethik, die ueber das hinausgehen, was als Ethik der Technik bisher konzipiert worden ist. Das betrifft auch den Zusammenhang von Ethik und Aesthetik. Dafuer sollte der Blick offen bleiben. (orig.)

Fuer die CTA wurden 120 ml KM i.v. appliziert. Nach {beta}-Blocker-Gabe war die Herzfrequenz zwischen 55 und 67 Schlaegen/min. Ergebnisse: Die Untersuchungszeiten betrugen 12s beim Ca-Score und 18s bei der CTA (Untersuchungsbereich 15 bzw. 12 cm). Der Volume Score lag zwischen 0 und 256,4. In der CTA konnte der gesamte Koronargefaessbaum einschliesslich der distal gelegenen, subsegmentalen Aeste bei allen Patienten artefaktfrei dargestellt werden. Bei zwei Patienten wurde ein Komplettverschluss der rechten Kranzarterie (RCA) bzw. des Ramus interventricularis anterior (RIVA) diagnostiziert. Letzterer Patient wies ein grosses linksventrikulaeres Vorderwandaneurysma auf. Schlussfolgerungen: Nach unseren bisherigen ersten Erfahrungen scheint die neue 16-Zeilen-Technologie eine sehr gute Darstellung des koronaren Gefaessbaumes mit Abgrenzbarkeit auch kleiner Gefaessaeste bis in die Peripherie aufgrund einer gesteigerten raeumlichen Aufloesung zu ermoeglichen. Die bei diesen Patienten erzielte Bildqualitaet laesst die Hoffnung auf eine verbesserte, nicht-invasive Herzdiagnostik aufkommen. In groesseren Studien muss jedoch diese neue Technologie bezueglich ihres klinischen Stellenwertes bei der Kardiodiagnostik untersucht werden. (orig.)

    Full Text Available The range and number of technologies currently available have yielded both opportunities and challenges for language educators. This study aims to review recent technology-enhanced language learning (TeLL research, and to examine their potential relevance to EAP pedagogy, curricula, assessment and instruction. The results of this study show TeLL research with rising interest in vocabulary, grammar and writing, but less so in speaking, listening, and reading. The results also reveal a shift from a tool-centric view of technology use to one that emphasises the technology-pedagogy-human alliance in the last decade, noting three emerging trends in recent TeLL studies, namely, those that are multi-purpose, multi-genre, and multi-role/skill in design and evaluation. The lack of a holistic approach to TeLL for EAP courses to date, however, has made it necessary and desirable to develop a framework for EAP-specific TeLL, to identify a principle for a generic TeLL programme, and to propound ways of operationalizing such a framework.

    This research project was sponsored by the federal ministry of science and technology BMFT (product owner: New Materials and Chemical Technologies - NMT). Its aim was to develop a novel unit that can work both as a pump and a turbine with a constant flow direction through internal blade adjustment. This specifically high-speed pump-turbine is suited for plants where a liquid in one case needs to be hauled against a rising pressure and where, in another case, there is a pressure drop in the same direction. So far, either a separate pump and turbine each are used which are temporarily stopped, involving corresponding effort, or - almost as a rule - the turbine is dispensed with, so that the energy locked up in the pressure drop goes unused. (orig.) [Deutsch] Die Zielsetzung unseres Forschungsvorhabens, das vom BMFT (Produkttraeger: Neue Materialien und Chemische Technologien - NMT) gefoerdert wird, war die Entwicklung eines neuartigen Aggregats, das durch interne Schaufelverstellung in der Lage ist, sowohl als Pumpe als auch als Turbine mit gleichbleibender Durchstroemrichtung zu arbeiten. Diese spezifisch schnellaeufige Pumpturbine kommt fuer Anlagen in Frage, in denen eine Fluessigkeit im einen Fall gegen einen anstehenden Druck gefoerdert werden muss und im anderen Fall in gleicher Richtung ein Druckgefaelle zur Verfuegung steht. Entweder werden bisher getrennt aufgestellte Pumpen und Turbinen mit zeitweisem Stillstand und entsprechendem Aufwand eingesetzt oder es wird - fast in der Regel - auf die Turbine und damit auf die im Druckgefaelle enthaltene Energie verzichtet.

    Hydrogen from fossil or renewable sources is an important fuel for low-emission power generation in fuel cells. Methanol and maybe also ethanol can also be produced by direct electrochemical processes in low-temperature fuel cells (PEMFC, PAFC). Fuel cell systems with high operating temperatures are highly flexible with regard to fuel but tend to have material problems. On the other hand, rapid developments in materials development and the possibility of production technology transfer from the electronics industry lead one to expect a breakthrough in the near future. But in spite of this, niche market applications will prevail. Since power stations have a longer life than motor vehicles and fuel cells in mobile applications, emission reductions from fuel cell applications in road vehicles are more probable on a medium-term basis than from applications in power stations. (orig.) [Deutsch] Wasserstoff, der sowohl aus fossilen wie auch aus regenerativen Quellen erschlossen werden kann, ist ein wesentlicher Brennstoff fuer die emissionsarme Elektrizitaetsproduktion in Brennstoffzellen. Methanol und eventuell Ethanol koennen auch direkt elektrochemisch in Niedertemperaturbrennstoffzellen (PEMFC, PAFC) umgesetzt werden. Brennstoffzellensysteme mit hohen Betriebstemperaturen erlauben eine hohe Flexibilitaet bezueglich der verwendeten Brennstoffe, sind aber nach wie vor durch starke Materialprobleme belastet. Die enormen Fortschritte in der Materialentwicklung einerseits sowie ein moeglicher Transfer von Fertigungstechnologien aus der Elektronikindustrie andererseits lassen eine zukuenftige grosstechnische Nutzung von Brennstoffzellen erwarten. Die technische Einfuehrung wird dennoch nur ueber Nischenmaerkte moeglich sein. Da die mittlere Lebensdauer eines Kraftwerks deutlich hoeher ist als die eines Strassenfahrzeugs, ausserdem Brennstoffzellen auch in staerkerem Masse in Fahrzeugen eingesetzt werden koennen, sind mittelfristig Emissionen eher durch Brennstoffzelleneinsatz in Strassenfahrzeugen als in Kraftwerken reduzierbar.

Technologie ochlazování pomocí dusíku představuje dvě varianty - použití kapalného dusíku nebo plynného dusíku v prostoru uzavřených důlních děl. Z technicko-bezpečnostního hlediska je aplikace kapalného dusíku již dnes považována za nevyhovující, naproti tomu aplikace plynného dusíku se jeví jako vysoce bezpečná technologie ochlazování výbuchuvzdorně prostorově uzavřeného požářiště. Další z možností ochlazování požářišť v hlubinných uhelných dolech představuje tzv. přirozené ochlazování, kdy jsou sice ekonomické náklady nulové, ovšem ve srovnání s ochlazovacími procesy vyvolanými aplikací chladících technologií však delší doba potřebná k přirozené refrigeraci požářiště způsobuje finanční ztráty.

    }. With the ability to perform in-reactor measurements a new phase of more meaningful experiments is just starting. These will determine whether any potential economic advantage lies in novel forms of fuel. Meanwhile, continuing development of sintered UO{sub 2} in the simple rod geometry will provide stiff competition. (author) [French] Maintenant que plusieurs reacteurs alimentes au bioxyde d'uranium sont en exploitation normale, on peut considerer que les performances nucleaires de cette matiere sont satisfaisantes et il faut se rejouir de voir se realiser encore de nouveaux progres dans cette branche de la technologie. L'evenement le plus remarquable dans ce domaine est assurement la decouverte des chercheurs de Battelle qui ont observe recemment qu'a haute temperature un monocristal de UO{sub 2} etait doue d'une tres forte conductivite thermique. A la suite d'une controverse sur ce point, une experience d' irradiation faite a Chalk River a montre que les grains de grande dimension formes dans des elements combustibles en fonctionnement ne presentent pas necessairement cette conductivite accrue. Les experiences de laboratoire ont revele que cette augmentation de la conductivite ne se presente que dans les compositions hypostoechiometriques et ne depend guere de l'absence de joint de grain. En fait, la forte conductivite peut etre obtenue dans des frittes polycristallins, si l'on maintient la composition stoechiometrique optimum. On sait depuis longtemps qu' il est possible de reduire rallongement des gaines en menageant des depressions sur chacune des bases des pastilles de UO{sub 2}; on a montre par la suite que si on laissait un vide aux extremites de l'empilement des pastilles, la tendance du combustible a remplir ce vide etait entravee par la dilatation diametrale des pastilles et leur interaction mecanique avec la gaine. On a realise un tres grand progres en vue de reduire los distensions de la gaine lorsqu'on s'est rendu compte que les dilatations longitudinales

    Results of measurements on an indirect adiabatic dew point cooling system are presented and discussed. The cooling system has been developed by OxyCom (formerly ComfortAir), Raalte, Netherlands. [Dutch] De techniek van dauwpuntskoeling is gebaseerd op bet principe van indirecte verdamping van water in een secundair circuit, waarbij geen extra vocht aan de te koelen luchtstroom wordt toegevoegd en waarmee luchttemperaturen worden bereikt die net boven het dauwpunt liggen en dus onder de natteboltemperatuur. Dauwpuntskoeling is een technische ontwikkeling met goede toekomstverwachtingen. Voorzover bekend zijn er tot op heden geen meetgegevens gepubliceerd met een dergelijke indirect werkende koeler. Dit artikel geeft de meetresultaten weer van een door OxyCorn in samenwerking met TNO-MEP uitgevoerd meetprogramma. Dit artikel is gebaseerd op de TNO-MEP rapportage met als auteurs N.R. Bootsveld en J. Afink en heeft eerder in het blad Koude en Luchtbehandeling, januari 2003, gestaan.

  10. A REVIEW ON BIOMASS DENSIFICATION TECHNOLOGIE FOR ENERGY APPLICATION

    Energy Technology Data Exchange (ETDEWEB)

    JAYA SHANKAR TUMULURU; CHRISTOPHER T. WRIGHT

    2010-08-01

    The world is currently facing challenges to reduce the dependence on fossil fuels and to achieve a sustainable renewable supply. Renewable energies represent a diversity of energy sources that can help to maintain the equilibrium of different ecosystems. Among the various sources of renewable energy, biomass is finding more uses as it is considered carbon neutral since the carbondioxide released during its use is already part of the carbon cycle (Arias et al., 2008). Increasing the utilization of biomass for energy can help to reduce the negative CO2 impact on the environment and help to meet the targets established in the Kyoto Protocol (UN, 1998). Energy from biomass can be produced from different processes like thermochemical (combustion, gasification, and pyrolysis), biological (anaerobic digestion, fermentation) or chemical (esterification) where direct combustion can provide a direct near-term energy solution (Arias et al., 2008). Some of the inherent problems with raw biomass materials, like low bulk density, high moisture content, hydrophilic nature and low calorific value, limit the ease of use of biomass for energy purposes (Arias et al., 2008). In fact, due to its low energy density compared to fossil fuels, high volumes of biomass will be needed; adding to problems associated with storage, transportation and feed handling at a cogeneration plant. Furthermore, grinding biomass pulverizes, can be very costly and in some cases impractical. All of these drawbacks have given rise to the development of new technologies in order to increase the quality of biomass fuels. The purpose of the work is mainly in four areas 1) Overview of the torrefaction process and to do a literature review on i) Physical properties of torrefied raw material and torrefaction gas composition. 2) Basic principles in design of packed bed i) Equations governing the flow of material in packed bed ii) Equations governing the flow of the gases in packed bed iii) Effect of physical properties of the raw materials on the packed bed design 3) Design of packed bed torrefier of different capacities. 4) Development of an excel sheet for calculation of length and diameter of the packed bed column based on the design considerations.

(author) [French] Si les emetteurs beta ne sont pas entres en ligne de compte en tant que sources de rayonnement de grandes dimensions, c'est que dans le passe les procedes sous irradiation presentant un interet pour l'industrie etaient bases sur l'utilisation de particules a grand pouvoir de penetration; de la l'importance considerable que l'on accordait aux rayons gamma et aux electrons artificiellement acceleres. Il y a environ quatre ans, il devint evident que de vastes perspectives s'ouvraient aux applications pratiques des rayonnements beta dans le domaine du traitement par irradiation superficielle, par exemple, la modification par copolymerisation greffee de la surface des moulages en matiere plastique et la pasteurisation superficielle des aliments. En effet, l'irradiation en profondeur occasionne dans ces cas des pertes et peut meme presenter des dangers. D'autre part, il y a deux autres domaines dans lesquels l'utilisation des electrons artificiellement acceleres ne semble pas indiquee; ce sont les syntheses chimiques amorcees par irradiation dans des cuves sous pression et certaines categories de reactions en chaine provoquees par des radicaux libres pour lesquels le taux de production par kilowatt decroit en fonction de la racine carree de l'intensite d'irradiation. Dans tous ces domaines, les sources beta de grandes dimensions presentent des avantages potentiels evidents; puisque la fission nucleaire permet d'en obtenir en quantites importantes, elles meritent que leurs- possibilites d'utilisation fassent l'objet d'un examen approfondi. Compte tenu de ces considerations, on a procede - sous l'egide de la Commission de l'energie atomique - a une etude des applications'et de la technologie des sources beta de fission.

    The mechanical design of packaging containers for radioactive material transport and storage using numerical techniques is a resilient and sufficient exact prediction of the mechanical loads due to drop accident scenarios. The correct simulation of energy dissipation of the involved shock absorbing components and materials is of main importance. The behavior of components and materials is dependent on deformation speed and environmental conditions, esp. temperature. Within the research project QUEST numerical methods based on compression test results from different damping materials are developed for the optimization of mechanical load simulation. Test results are described for polyurethane foam, wood and damping concrete. The finite element based simulation is aimed to develop and verify material models based on the experimental material reference curves.

    One goal of the study was the evaluation of single greenhouse gas reduction measures which are part of the national climate protection program initiated in the year 2000 by the German Government. Within the project the potentials of greenhouse gas emissions reduction of single measures have been quantified up to the year 2010. Taken all the impacts of the measures into account, it seems to be possible to reduce the overall greenhouse gas emissions by nearly 20 % by the year 2010. 70 % of the reduction is caused by CO2 emissions reduction and 30 % by a reduction of other non-CO2 emissions. It should be emphasised that 38 million tonnes of CO2 can be reduced by forcing the use of renewable energies. However, to achieve the German's ''burden sharing'' goal of a 21 % emissions reduction by the year 2010 additional measures will be necessary. To analyse emissions reduction strategies for a long-term view (up to 2030) additional scenarios have been developed. The analysis shows that there are still technical options to reduce CO2 emissions by 30 to 40 % by the year 2030. In the case of such ambitious reduction targets measures in all sectors of the energy system have to be implemented. The costs of the different mitigation strategies are strongly correlated with the framework of energy and climate protection policies. (orig.)

    Extensive experiments on combustion of biological materials and residues in fluidized bed combustors and dust combustors have been carried out at the Department of Power Plant Engineering of Dresden University since the early nineties. Particular interest was taken in mixing brown coal with sewage sludge, sugar pulp and waste wood. The experiments were supplemented by modelling in a research project funded jointly by the BMBF and Messrs. Lurgi since early 1997. A combustion cell model designed by Siegen University is being modified for the new mixed fuels, and preliminary investigations were carried out on a batch reactor while the modelling work was continued. (orig.) [Deutsch] An dem Lehrstuhl fuer Kraftwerkstechnik der TU Dresden werden seit Anfang der 90-iger Jahre umfangreiche experimentelle Untersuchungen zur Verbrennung von Bio- und Reststoffen in Wirbelschicht- und Staubfeuerungen durchgefuehrt. Dabei war vor allem die Zufeuerung dieser Stoffe in Waermeerzeugeranlagen auf Braunkohlenbasis von besonderem Interesse. Experimentell konnte nachgewiesen werden, dass sowohl Biobrennstoffe als auch Abfaelle in zirkulierenden Wirbelschichtfeuerungen umweltschonend zur Waermeerzeugung eingesetzt werden koennen. Als Beispiel wird das an Hand von Braunkohle-Klaerschlammgemischen sowie Bagasse- und Holz-Braunkohlegemischen gezeigt. Neben den experimentellen Untersuchungen bietet die Modellierung der Verbrennungsvorgaenge ein geeignetes Mittel um Voraussagen zu anderen Mischungsanteilen sowie anderen geometrischen Abmessungen machen zu koennen. Seit Anfang 1997 wird dazu ein vom BMBF und der Firma Lurgi gefoerdertes Forschungsvorhaben bearbeitet. Ein von der Universitaet Gesamthochschule Siegen fuer die Braunkohleverbrennung konzipiertes Zellenmodell wird auf die neuen Brennstoffgemische erweitert. Da grundsaetzlich andere Stoffzusammensetzungen vorliegen, wurden an einem Batch-Reaktor Voruntersuchungen zum Pyrolyseverhalten der Brennstoffe durchgefuehrt. Erste

    This is the final report of the Technology Project 'NO{sub x} reduction by means of homogenisation of mixtures inside combustion chambers', which is part of the Engine 3E 2010 programme of the BMBF, which was to promote research in aircraft engineering. In this project, technologies were developed to achieve a 60% reduction of NO{sub x} emissions as compared to ICAO '95 in an annular combustion chamber in realistic operating conditions where the emissions of substances oher than NO{sub x} were to be of the same level as the emissions of modern jet drives. Further, the design of the new combustion chamber was to be conventional in order to retain the possibility of converting existing propulsion systems to the new technology. [German] Diese Notiz enthaelt den Abschlussbericht des Technologievorhabens 'NO{sub x}-Reduktion durch Homogenisierung des Gemisches in Brennkammern'. Das Vorhaben ist Teil des Luftfahrtfoerderprogramms Engine 3E 2010 der Bundesregierung und wird vom Bundesministerium fuer Bildung, Wissenschaft, Forschung und Technologie (BMBF) unter dem Foerderkennzeichen 20T9540 gefoerdert. Das Programm wurde am 01. Juli 1995 begonnen und endete am 30. Juni 1999. Entsprechend dem Foerderantrag wurden in dem Vorhaben Einzeltechnologien erarbeitet, die erforderlich sind, um eine 60% Reduktion der NO{sub x}-Emissionen gegenueber ICAO '95 in einer Ringbrennkammer unter realistischen Betriebsbedingungen zu demonstrieren, wobei die restlichen Emissionen das Emissionsniveau moderner Triebwerke nicht ueberschreiten sollten. Darueber hinaus sollte das aeussere Design der zu entwickelnden Brennkammer sind von konventionellen Brennkammern nicht unterscheiden, um die Moeglichkeit der Umruestung von alten Triebwerken mit der Brennkammern der neuen Technologie offen zu halten.

    Full Text Available Many countries are engaged in renovating science and technology teaching in secondary schools. In order to give more coherence to the content taught, the place and definition of the school subjects involved tend to be reexamined. In France, an integrated science and technology teaching program is being tested since 2006. A first analysis of the program and the way participating teachers view it has been done from the definition of several strategies to bring disciplines together. Four dimensions of school disciplinary integration have been identified to structure our reflexion. The analysis of posters produced by the teachers reveals an incomplete vision of integration and a dominant place given to notional knowledge.

    1993-01-01

    The principle of renewable raw materials, from the basic material to the end product, can be determined experimentally. A total of 65 experiments on lipids (natural fats and oils), carbohydrates, proteins, amino acids, wood constituents and tanning agents were developed. The experiments were chosen with a view to practical application. Examples are mass products like plastics, tensides, lacquers, foils, cellulose and leather, but also special applications as in the production of aromatics, pH indicator paper, or antioxidants for fruit essences. Synthetic-preparative processes are the most common. Analytical methods are applied wherever reaction control is required for further processing or characterisation of a product. (orig.)

    1997-03-01

    An outline is given of the chances and threats of technological developments for the environment in the next 25 years. First, the most important technological supply-side developments were inventorized and assessed for their environmental relevance and in the light of three CPB-scenarios. From the results of the analysis it appears that their are many options to improve the environmental efficiency of products and processes. An important motive to develop environment-efficient technology is the price of energy. A higher price for energy will stimulate the development of energy efficient products and processes. Also the interest for dematerialization will increase while the processing of basic materials and the use of materials requires energy too. A second important motive is the demand for environment-efficient products. The market introduction of new environment-friendly products strongly depends on the quality consciousness (including the environmental quality) of the consumer. With respect to the environmental policy it can be concluded that technological innovation is important in the transfer of a decontamination-based policy to a prevention-based policy. 95 refs.

Il recueille, à priori, naturellement, l’adhésion de chacun, élèves, équipe éducative et parents. Il est enfin une occasion d’avoir une approche différente de celle de la classe, les élèves étant confrontés au vivant dans son environnement. Lors de ces activités proposées dans ce contexte, leur rapport au vivant est directement confronté à la réalité. Quels sont les enjeux didactiques d’une pédagogie axée autour d’activités au jardin expérimental ? A partir de deux activités ; un « totem à insectes » et un « nichoir connecté ».

    This project started on 1 January 1996 with DM 3.7 million funds from the BMFT. Originally scheduled for three years, it was extended by a further 11 months for various reasons. Its intention was to reduce the cost of future solar thermal power plants. Particular emphasis was given to the parabolic trough technology asit is closest to commercialisation. Three strategies were involved: 1. Further development and qualification of components for the parabolic trough collector (WG PAREX); 2. Development of instruments for measuring radiation flux distribution in parabolic trough collectors (WG PARMESAN); 3. Development, verification and application of software tools for analysing the complex dynamic response of solar thermal power plants (WG SISTA). [German] Das hier dargestellte Projekt begann am 1.1.1996 und wurde vom Bundesministerium fuer Forschung und Technologie (BMFT) mit etwa 3,7 Mio. DM gefoerdert. Es hatte eine geplante Laufzeit von drei Jahren, wurde aber aufgrund von unterschiedlichen Verzoegerungen (Mitarbeiterwechsel, Defekte an Versuchsanlagen) kostenneutral um 11 Monate verlaengert. Gesamtziel des Projekts war es, zur Kostensenkung bei zukuenftigen solarthermischen Kraftwerken beizutragen. Dabei stand insbesondere die Parabolrinnentechnik im Vordergrund, da sie im Vergleich zu anderen solarthermischen Technologien einer weiteren kommerziellen Vermarktung derzeit am naechsten steht. Es wurden drei Schwerpunkte verfolgt: 1. Die Weiterentwicklung und Qualifizierung von Komponenten fuer den Parabolrinnenkollektor (Arbeitspaket 'Parabolrinnenexperimente', kurz PAREX) 2. Die Entwicklung von Messtechnik zur Bestimmung von Strahlungsflussverteilung bei Parabolrinnenkollektoren (AP 'Parabolrinnen-Messanlage', kurz PARMESAN) 3. Die Erstellung, Verifikation und Anwendung von Softwarewerkzeugen zur Analyse des komplexen dynamischen Verhaltens von solarthermischen Kraftwerken (AP 'Simulation solarthermischer Anlagen', kurz SISTA) (orig.)

    In spring 1990, the Federal German Minister for Education, Science, Research and Technology (BMBF) commissioned the team from the Federal Institute for Materials Research and Testing (BAM), DEKRA, Daimler-Benz, the Federal Road Research Institute (BASt) with the University of Cologne, Ellinghaus and TUeV Rheinland (project leader) to perform the research project `THESEUS` (the acronym THESEUS comes from the German `Tankfahrzeuge mit hoechst erreichbarer Sicherheit durch experimentelle Unfallsimulation`, which translates as `achieving maximum possible road transport tanker safety by means of experimental accident simulation`). Arting from an analysis of road transport tanker accidents, crash tests and overturn tests were performed and supplemented by investigations of road transport tanker components and accompanying complex calculations of the failure processes. Parallel to this, the static side-tilt stability of road transport tankers was determined on a tilting test platform. The causes of and constructive possibilities for avoiding overturning, which is the most common cause of accidents in which hazardous materials escape, wewre analysed in dynamic driving tests with supplementary computer simulation. Various measures for improving the safety of road transport tankers were determined and subjected to a cost-benefit analysis. (orig.)

    The aim of the research project is the development of a technique for value for money mass-production of large area holographic focussers made of dichromate gelatine for photo-electrics. The holograms act simultaneously as spectrally dispersing and focussing optical elements, which focus the sunlight in discrete bands on the spectrally matched solar cells. The three marked characteristics of the holographic focussers are the diffraction efficiency, the spectral bandwidth and the central working wavelength. The optimum values of these parameters depend on the variation of the layer thickness and the index of refraction over the aperture of the hologram, and on the ability of the DCG layer to provide great modulation of the index of refraction. Mass-production of large format holographic lenses (transmission holograms) and mirrors (reflection holograms) demands precise coating of the supporting substrate (glass or PET foil) with dichromate gelatine. Mass-production of the holographic lenses requires a matrix hologram with 50% diffraction efficiency and is done with two copier plants developed in the project. (orig./AKF) [Deutsch] Ziel des Forschungsvorhabens ist die Entwicklung einer Technologie fuer die preiswerte serielle Herstellung von grossflaechigen holographischen Konzentratoren in Dichromatgelatine fuer die Photovoltaik. Die Hologramme wirken gleichzeitig als spektral dispergierende und fokussierende optische Elemente, die das Sonnenlicht in diskreten Baendern auf spektral angepasste Solarzellen konzentrieren. Die drei kennzeichnenden Charakteristiken der holographischen Konzentratoren sind die Beugungseffizienz, die spektrale Bandbreite und die zentrale Arbeitswellenlaenge. Die optimalen Werte dieser Parameter sind durch die Variation der Schichtdicke und des Brechnungsindexes ueber die Apertur des Hologramms, sowie durch die Faehigkeit der DCG-Schicht grosse Brechungsindexmodulation zu ermoeglichen, eindeutig bedingt.

    PLC (Power Line Communications) in Europe or BPL (Broadband over Power Lines) in the US are techniques that allows the utilization of low and middle voltage power lines for the transmission of high frequencies by coupling electrical signals to them. In this way, unshielded power lines may be used for the transmission of numerical information similar to the well known xDSL-techniques using telephone lines. Typically, the frequency range used by PLC is between 9 kHz and 30 MHz. The authors describe the general principles and investigate possible electromagnetic interference with existing radio frequency equipment like xDSL, CATV (Cable Television) and Wireless (GSM, Bluetooth, WiFi). Finally, they present theoretical and experimental results of techniques allowing the reduction of such interference by reducing the emission of electromagnetic signals from PLC systems. The preferred method is based on an active control by injecting an auxiliary signal into the third conductor (ground)

    The first part of the book describes the development of a polarised spectrum of attitudes towards science and technology over the last two decades. Positivistic attitudes that emerged from the materialistic branch of the period of Enlightenment are shown in contrast to the attitudes that stem from the philosophical line of Rousseau-romanticism-vitalism. The second part of the book presents the results of an empirical study, providing evidence for the existence of the different attitudes towards technology and the environment. The study is based on a representative opinion poll among civil servants, engineering professions, social workers, and artists. Engineers and social workers are shown to represent the two antipodes in terms of the 'dual-culture' theory. In addition, sex-specific and age-specific differences are explained, and the different pictures of technology drawn by personalities characterised by an attitude of active control in contrast to those characterised by an attitude of intuitive faith.

    The sound quality of interior and exterior vehicle noise is gaining more and more importance. Not only that modern vehicles show a considerably lower noise level, the characteristic sound of a vehicle influences the buyer`s choice of a car. The acoustic engineer is faced with a complex task. In addition to reducing the noise level he has to make sure that the sound design goes along with the product. This is where aurally-adequate sound diagnosis is needed. Conventional methods, e.g. measuring the noise level or third-octave spectrum, alone cannot solve this specific task. HEAD acoustics offers the full range of aurally-adequate measurement and analysis systems, starting with the Artificial Head Measurement System and making the recorded data available for further analysis with the Binaural Analysis System BAS or the Mobile Sound Quality Laboratory SQlab. This full range of systems helps the acoustic engineer to solve his tasks for improving sound quality in a fast and cost-effective way. (orig.)

    The diesel fuel injection equipment will remain a key element for diesel engine technology evolution. Achieving emission targets at competitive prices has been and will continue to be a major technical challenge to the engine manufacturer. Delphi is continuously developing its common rail system and its components to fulfill future stricter emission legislation while simultaneously improving performance on noise, fuel consumption and power output. This paper will describe the latest developments that delphi introduced into the market in their common rail system to comply with future legislative emission targets. Further, a novel common rail injector will be presented, that uses a revolutionary, direct acting operating principle, where the nozzle is directly operated by a piezo actuator, without the use of a servo-hydraulic flow circuit. The superior performance of this injector concept will be shown, especially in minimum quantity capability as well as multiple injection performance. The direct acting operating principle allows rapid opening and closing of the injector, without compromising pilot quantity capability. The emission benefit obtained by such opening and closing behavior will be shown. Finally, based on the findings discussed, the paper will conclude on key features of future common rail systems.

    (BMU) following a resolution by the German Federal Parliament and attended by a Working Group of the Forschungsvereinigung Verbrennungskraftmaschinen e.V (FVV, Research Association for Combustion Engines). (orig.) [German] In der Vergangenheit wurden an Biogasmotoren immer wieder Grenzwertueberschreitungen der in der Technischen Anweisung zur Reinhaltung der Luft (TA Luft) limitierten Formaldehydemissionen festgestellt. Fuer die zukuenftige Einhaltung dieses Grenzwertes an bestehenden und neuen Anlagen wurden am Lehrstuhl fuer Verbrennungskraftmaschinen der Technischen Universitaet Muenchen im Rahmen des FVV-Forschungsvorhabens 918 die Ursachen und die Moeglichkeiten zur innermotorischen Verminderung dieser Emissionen untersucht. Dabei zeigte sich, dass die Formaldehydemissionen nur sehr eingeschraenkt durch innermotorische Massnahmen verringert werden koennen, ohne Wirkungsgrad und Stickoxidemissionen negativ zu beeinflussen. Dies und eine zusaetzliche Verschaerfung der Grenzwerte im Januar 2009 durch LAI-Beschluss machen den Einsatz von Abgasnachbehandlungstechniken notwendig. Wegen der fehlenden Datenbasis ueber das Langzeitverhalten solcher Systeme im Biogasbetrieb wurden deshalb in einem weiteren Vorhaben zwei Modellanlagen mit unterschiedlichen Technologien zur Abgasnachbehandlung ueber sechs Monate hinweg hinsichtlich ihrer Formaldehydemissionen ueberwacht. Im Hinblick auf die aktuelle Klimadebatte und die Klimawirksamkeit von Methan, die eine zukuenftige Begrenzung dieser Emissionen erwarten laesst, wurden darueber hinaus auch die Methanemissionen dieser Anlagen untersucht. Die Untersuchungen zeigten, dass beide betrachteten Abgasnachbehandlungstechnologien, Regenerative Thermische Oxidation (RTO) und Oxidationskatalysator (Oxi-Kat) grundsaetzlich geeignet sind, die geltenden Formaldehydgrenzwerte sicher zu unterschreiten. Es wurde jedoch auch klar, dass weiterer Forschungsbedarf hinsichtlich der Dauerhaltbarkeit des Oxi-Kats und dem Instationaerbetrieb des RTO

    Thermal in situ rehabilitation technologies are a promising alternative to conventional methods of cleaning up contaminated sites. The fact that an increase in temperature changes the physical properties of materials makes it possible, in principle, to release large quantities of pollutants within short time periods. The use of pure steam or steam/air mixtures as fluid thermal carriers permits converting subterranean non-aqueous-phase pollutants into the gas phase through increased vapour pressure and transporting them to the surface by means of soil air aspiration for further treatment. The purpose of the present two-stage research project was to systematically develop a thermal in situ rehabilitation technology using steam as fluid heat carrier and use it for land rehabilitation operations on a pilot basis. In the first, fundamental project phase aspects of heat transport (Faerber, 1997) and pollutant behaviour (Betz, 1998)in homogenous porous media upon pure steam injection were explored at a laboratory and technical scale using containers of different sizes (1D, 2D, 3D). The results were used to derive application criteria for this technology. [German] Thermische In-situ-Sanierungstechnologien stellen bei der Reinigung kontaminierter Standorte eine vielversprechende Alternative zu konventionellen Verfahren dar. Die Veraenderung physikalischer Stoffeigenschaften mit steigender Temperatur ermoeglicht grundsaetzlich hohe Schadstoffaustraege innerhalb kurzer Zeitraeume. Beim Einsatz von reinem Wasserdampf oder Wasserdampf-Luft-Gemischen als Waermetraegerfluid koennen im Untergrund in nicht waessriger Phase vorliegende Schadstoffe hauptsaechlich wegen der erhoehten Dampfdruecke in die Gasphase ueberfuehrt, ueber eine Bodenluftabsaugung an die Oberflaeche transportiert und dann einer weiteren Behandlung zugefuehrt werden.

    Through this research we will fully assess the benefits brought by the ExAO (Computer Assisted Experimentation) in school laboratories of science and technology in Lebanon. We would also like to mention its contribution in a tangible way in laboratory research of Pedagogic Robotic from Montreal University, particularly in the development of ExAO mulaboratory. We wanted to test the capabilities of the ExAO, its use in the classroom such as: 1. A replacement of a traditional laboratory in the use of the experimental method. 2. A scientific investigation tool. 3. An integration tool of experimental sciences and mathematics. 4. An integration tool of experimental sciences, mathematics and technology in the technoscientific learning. To do so, we have mobilized 13 group classes, designated teachers to experiment themselves along with their students in order to assess, in a more realistic way, the benefits of implementing this micro computer laboratory at school. Different testing, evaluated using the results of learning activities undertaken by students, their responses to a questionnaire and feedback from teachers, show that: 1. The replacement of a traditional laboratory with an ExAO mulaboratory does not seem to pose problem, expected that students have adapted to it in only ten minutes, indicating that the speed with which data were graphed was more productive. 2. In order to investigate a physical phenomenon, the usability of the tutorial associated with the ability to amplify the phenomenon before its graph representation, has allowed students to design and implement quickly and independently an experiment to verify their prediction. 3. The integration of mathematics into an experimental approach can quickly grasp the phenomenon. In addition, it gives more autonomy and a meaning to the graphs and algebraic representations allowing to use them as a cognitive tool to interpret this phenomenon. 4. The approach made by the students to design and construct a technological object, showed that this activity was easily carried out by the use of universal sensors, amplifiers to offset the graphical modeling tool, and the tutorial ability to transform any measured variable by another variable (for instance, the resistance variation in temperature change, ...). This educational activity shows that students had no difficulty integrating in a single learning activity the mathematics, experimental sciences and technology, in order to design and implement a functional piece of technology. The ExAO mulaboratory, by offering new educational opportunities, such as the ability to design, produce and validate a technological object, in order to do so, new capacities to boost measures, modeling physical phenomena, developing new sensors, is an important addition to the experiments being conducted in ExAO. Keywords: ExAO, teaching, integration, Lebanese schools.

    The Guidebook serves as a handbook for the entire operational sequence, which is necessary for the establishment of a wood combustion plant in Germany with an installed capacity larger than 100 kW{sub th}, for the use of fuel woods such as forest chips, wood and forest residues, pellets, wood waste, etc. within the limits of the laws and regulations prescribed for the respective performance classes. The Guidebook's purpose is to give potential investors and operators of wood combustion plants as well as the appropriate authorities a quick and global overview of the energetic use of wood in order to contribute to an increased application of this technology. The Guidebook introduces a Quality Model in Chapters 2 and 3, which describes the establishment of a wood combustion system in six phases. Eleven Management Aspects are differentiated, which can be helpful during the conversion of a project. Thus, potential investors and operators of wood combustion plants become acquainted with the most important aspects of this kind of project conversion. In addition, Chapter 4 provides an overview of the operating costs of wood combustion plants. The relevant licensing and planning procedures depending on the installed capacity and fuelwood use are comprehensively described in Chapter 5. Chapter 6 supplies a concrete overview of the environmental aspects and emissions of wood combustion. Since wood combustion plants must be - as all other investments - financially secured Chapter 7 provides a description of the relevant information on public means and subsidies. Besides all important promotion programmes, the new German Renewable Energy Law (Erneuerbare-Energien-Gesetz - EEG) of April 2000 is described in detail. Many examples of already realised wood combustion plant projects are described in Chapter 8. As an additional service, all significant addresses from ministries to energy agencies and associations are listed in Chapter 9. (orig.)

Through their joint venture UHDENORA S.p.A., ThyssenKrupp Uhde and Industrie De Nora S.p.A. have played a major part in the development of a globally available technology that can produce chlorine using up to 30 percent less energy than conventional processes. It uses oxygen depolarized cathode technology with an innovative new cathode chamber design in an Uhde single-cell element. In Germany alone, converting all existing plants to the new technology would save enough electricity to power a city the size of Cologne. (orig.)

    The electronics associated to the particle detectors of the Large Hadron Collider (LHC), under construction at CERN, will operate in a very harsh radiation environment. Most of the microelectronics components developed for the first generation of LHC experiments have been designed with very precise experiment-specific goals and are hardly adaptable to other applications. Commercial Off-The-Shelf (COTS) components cannot be used in the vicinity of particle collision due to their poor radiation tolerance. This thesis is a contribution to the effort to cover the need for radiation-tolerant SEU-robust programmable components for application in High Energy Physics (HEP) experiments. Two components are under development: a Programmable Logic Device (PLD) and a Field-Programmable Gate Array (FPGA). The PLD is a fuse-based, 10-input, 8-I/O general architecture device in 0.25 micron CMOS technology. The FPGA under development is instead a 32x32 logic block array, equivalent to ~25k gates, in 0.13 micron CMOS. This wor...

  10. The relationship of family relations and interpersonal skills with communication technology [Więzi rodzinne i umiejętności interpersonalne a technologie komunikacyjne

    2017-11-01

    Full Text Available The paper presents the role of proper relations within the family environment in a child’s social development and its influence on the quality of future relations with other people. Emphasis is put on the importance of a child’s first relations in its emotional development and the necessity to support a young person on their way to independence as a means of protection against loneliness and desperate attempts to seek social relations through communication technology. The function of affection is fundamental to a person’s development. The theory of affection explains the different forms of human emotional functioning. The author defines four patterns of affection: a trustful, an anxious and avoidant, an anxious and ambivalent, and a disorganised relation. Improper models cause developmental disorders. They influence a person’s entire life, their social skills and interpersonal relations. They result in problems with coming into one’s own, finding one’s identity, establishing proper relationships with one’s peers which constitute a great value for a young person. Improper attitudes of adults frequently block the development of autonomy and proper relationships of teenagers. The lack of relations with peers leads to anxiety and fear of loneliness, incapability of fulfilling the need to belong to a group initiates defensive mechanisms. For some they may lead to looking for contacts on the internet. The computer screen serves as a shield, it relieves one of the feeling of loneliness, leads to feeling of well-being. With its role as a substitute of peer relations in the real world, the internet may be a form of spending leisure time, a source of topics for discussion and games, a facilitator of identification with a peer group and its values, and even a plain for the development of individual identity. Media not only create social and educational chances, but they are also a source of dangers and addictions. The effects of internet addiction may take on various forms. The so-called paradox of the internet needs to be mentioned. Although the internet is used to communicate with others, its use leads to a weakening of the relations with one’s environment and increasing the feeling of loneliness. In order to support young people in establishing responsible and satisfying relations they should be provided with help in acquiring social skills which are the basic source of relations of affection and proper upbringing styles

    Full Text Available Health care resource allocation is a complex governmental task involving political decisions that are bound to be influenced by the various needs of the population and the demands of health professionals. What influence should these different interests have on the integration of new technologies into the health care system? Pharmacogenomics, a new field in the pharmacological sciences that integrates into the drug development process genomic information developed through the Human Genome Project, has been proposed as a technology that promises to make medical practices more personalized. Its integration in drug development or prescription processes could help reduce the risk of adverse drug reactions characteristic of pharmaceutical treatments. Considering the actual allocation of health care resources in Quebec, should the provincial government invest in the integration of pharmacogenomics as a new tool for drug development or drug specification? This question will be addressed using the criteria previously described by Caulfield and colleagues (2001 in order to assess the justification of public financing for genetic testing[1], i.e., moral acceptability, utility, safety and the requirement of a noticeable benefit at an acceptable cost for society. Given the proximity of the fields of genetics and genomics, these criteria are applicable to our discussion.

The PLD is a fuse-based, 10-input, 8-I/O general architecture device in 0.25 {mu}m CMOS technology. The FPGA under development is a 32*32 logic block array, equivalent to {approx} 25 k gates, in 0.13 {mu}m CMOS. The irradiation test results obtained in the CMOS 0.25 {mu}m technology demonstrate good robustness of the circuit up to an LET (Linear Energy Transfer) of 79.6 cm{sup 2}*MeV/mg, which make it suitable for the target environment. The CMOS 0.13 {mu}m circuit has showed robustness to an LET of 37.4 cm{sup 2}*MeV/mg in the static test mode and has increased sensitivity in the dynamic test mode. This work focused also on the research for an SEU-robust register in both the mentioned technologies. The SEU-robust register is employed as a user data flip-flop in the FPGA and PLD designs and as a configuration cell as well in the FPGA design.

    Full Text Available The programs of physics and technology teachers’ preparation in Greece are described in this study. The purpose is to search the role of science and technology education considered in this study as the teaching point of view which starts from the content knowledge. We have mentioned several systems depending on the specialization of the teacher and the faculty from which he/she graduates. Our study, based on information provided by official sites of the faculties, shows that science and technology education is not sufficiently present in preparation programs. Moreover, from the various aspects of science and technology education the one that is chiefly missing is that of the researcher that privileges a critic and prospective point of view concerning teaching.

    Full Text Available Abstract Few researchers have examined learners’ preferences for different types of technological activities in the second-language classroom. This study is an initial effort to identify which technological activities are currently used by university-level FSL students in the language classrooms and which activities and formats these learners prefer and find useful. Data was collected from students taking courses in French as a second language in three different universities. A series of questionnaires was used to assess language skills, gather demographical information and elicit preferences for technological activities. Results indicate that, in general, the students have positive perceptions of the technological activities used in their language classroom even though they don’t use them very often. Students report appreciating some technological activities but don’t find them very useful for language learning while other activities are judged useful but are not appreciated by the students. The results are presented as a continuum of activities ranked by their perceived usefulness and student appreciation. These are followed by recommendations for language teachers about the use of these activities in their classrooms.

    In Germany, several gas companies are currently prospecting for so-called unconventional natural gas reservoirs (shale gas and coal bed methane) in many parts of the country using the fracking technology (hydraulic fracturing). Therefore, a mixture of water, chemicals and sand is forced in the reservoir rock under high pressure in order to mobilize the enclosed gas. To address the sometimes massive public concerns about the safety and the environmental compatibility of the fracking technology the 'Dialogue and information dissemination process concerning the health and environmental aspects of hydrofracking' has been initiated. During the process recommendations have been developed by a panel of experts to promote a thoughtful, realistic and fact-based debate on the vices and virtues of hydrofracking. (orig.)

    2012-01-01

    Full Text Available Toxic principles, toxicity and technology of detoxification of Jatropha curcas L. seed: a review. The use of meal from the crushing of Jatropha curcas seed for livestock feed is limited owing to the variable amounts of seed available. This availability depends on the level and variety of toxic and antinutritional compounds contained in the seed at a given time; the most important of these compounds are phorbol esters and curcin. The phorbol esters present in J. curcas seed are Euphorbiaceae diterpenes, known for their inflammatory action resulting in irritation and toxicity to insects, fish and mammals. These compounds are sometimes completely degraded in soil and they may be reduced by physical, chemical or biological processes, with a reduction ratio of between 50 and 95%. Curcin is an irritating toxalbumin with lectin activity; it is inactivated by heat treatment at 121 °C for 30 min. Other antinutritional compounds are also present in J. curcas seed, such as saponins and an inhibitor of trypsin activity. This trypsin-inhibiting compound interferes with the digestion process and its reduction is achieved through thermal, chemical or biological treatments. The elimination of, or at least a reduction in the levels of, these molecules represents a prerequisite for using J. curcas meal in the livestock feed sector.

    Full Text Available Released in 2011, the British science-fiction television series Black Mirror, created by Charlie Brooker, has gained viewers’ recognition across the world (confirmed by winning Best TV Movie/Mini Series at the International Emmy Awards in 2012 and the announcement of the 3rd season. Using ‘black humour’ and satire, the series in a defeatist manner portrays dark side of media development and its influence on the future society. In the article I will focus on the phenomena brought up by Black Mirror creators – characters seduced by media, which instead of making their lives happier bring only pain and humiliation; the need for constant surveillance as invoked by more and more advanced technologies; pleasure coming from spying on others’ suffering or progressing simulation of reality. To illustrate these phenomena I will apply, among others, the notions of Guy Debord, Jean Baudrillard, Paul Virilio, and also Michel Foucault’s idea of the panopticon.

    This work is the first of a new research theme of the laboratory in the field of solid oxide planar fuel cells. With his high experience in the sensor field, the objectives were to realize prototypes using a 'low cost' technology like screen-printing, using classical materials in the field of fuel cells, rather than researching new materials having optimum properties which may be damaged during the realisation of the complete fuel cell. These materials are yttria stabilised zirconia (YSZ) for electrolyte, strontium doped lanthanum manganite (LSM) for cathode and a nickel oxide-YSZ cermet (NiO-YSZ) for anode. The first part of the study consists in structural and electrical characterizations of chosen materials, both on dense pellets and on screen-printed layers of YSZ, LSM or NiO-YSZ. These characterizations showed a good adequation of our materials for a fuel cell application. The second part consists in testing realised prototypes on electrolyte support and on anode support with screen-printed electrodes and electrolyte. The weak obtained performances are mainly due to the low functional temperature (800 C), the thickness of the electrolyte support (about 1 mm) and the porosity of the YSZ screen-printed layers. Finally, we tested in the same time an original device in which both electrodes are exposed to a fuel and air mixture. This promising device inspired from the research on potentiometric sensors developed in the team by N. Guillet (2001), avoids the tightness problem encountered with two gaseous chambers. Moreover, the performances obtained are just twice below than those obtained with a conventional fuel cell with two gaseous chambers. (author)

    LWD (Logging While Drilling) measurements are a potential alternative to conventional wireline logging for the optimisation of log data acquistion strategies in highly deviated or horizontal deep wells, and to safeguard petrophysical informations e.g. from partly depleted tight gas sands in the German Rotliegend formations. In this paper the results of the first sonic LWD 'slimhole' measurements in 5 7/8'' boreholes in Germany are presented and compared with conventional wireline logs and core data. Since 1996, BEB has meanwhile successfully run the Halliburton/Pathfinder SCLSS (Slimhole Compensated Long Space Sonic) LWD tool in four deep highly deviated, partly depleted wells as a cost effective and reliable alternative to conventional Coiled Tubing- or pipe conveyed wireline logging. In addition to a potentially reduced risk of operational problems (e.g. by differential sticking) in difficult wells, the LWD measurements have the further advantage to provide 'real time' measurements at nearly 'virgin' reservoir conditions, i.e. before a potential formation damage or saturation change by a deep invasion of drilling muds. This is especially relevant for the saturation evaluations from resistivity data. The analysis of the LWD sonic data and the comparison with wireline sonic logs and core data proved, that the sonic transit times from the shear wave arrivals can be regarded as more reliable than those from the compressional wave arrivals. Thus we recommend to preferentially use the shear wave data for petrophysical evaluations, e.g. for the determination of porosity. (orig.)

    Full Text Available Variability and Improvement of Maize Fermented Dough Traditional Technology Production in Congo. The poto-poto production proceeding is characterized by the large variability during some production stages, particulary in washing and conservation operations. The washing operation before and after steeping seems to be very important because it influences considerably the sensorial (colour, odour and hygienic qualities of final product. For improving nutritional qualities, germinated seeds utilization has been studied. With respect to biochemistry characteristics, poto-poto made with germinated seeds offers a diminution of lactic acid concentration and an increase of acetic concentration. By contrary, for poto-poto produced from ungerminated seeds, lactic acid concentration increases and that of acetic acid decreases. The two products are acid (pH 3,8 and pH 3,53 because of lactic and acetic presence. The sensorial test makes evident the sensorial differences existing in two types of products. The are two different products with respect to colour, taste, odour and texture. Poto-poto produced with maize germinated seeds is preferred (100% among tasters. It is slightly more sweet (100% among tasters and more sour (40% among tasters than poto-poto produced from ungerminated seeds. The poto-poto solar drying proceeding used allows a better conservation of poto-poto.

  7. Fuel Penalty Comparison for (Electrically Heated Catalyst Technology Comparaison de l’augmentation de consommation de carburant pour la technologie de catalyseurs chauffés à l’électricité

    Directory of Open Access Journals (Sweden)

    2010-03-01

    Full Text Available The conversion efficiency of three way catalytic converters is mainly defined by the temperature range wherein they are operating. Traditionally, ignition retard has been used to reduce the light-off time of the catalyst. This is however associated with a fuel penalty. With increasing vehicle electrification, electrically heating facilities present an alternative, especially for hybrid vehicles. Nevertheless, system complexity of hybrid vehicles prevents engineers to evaluate possible heating technologies and their corresponding fuel penalty with respect to traditional solutions. This paper evaluates the application of an electrically heated catalyst on a hybrid vehicle equipped with a Natural Gas (NG engine. The effect of heating power on light-off time and fuel penalty is determined, using analysis techniques emerging from integrated powertrain control. By means of a case study, the importance of an integral approach is explained by comparing the fuel penalty and conversion efficiency improvement of electric heating with that of ignition retard. In this process, a mix of simulation and test data were combined, forming the foundations for future control developments of a suitable light-off strategy. L’efficacité de conversion des catalyseurs est principalement définie par la gamme de température dans laquelle ils fonctionnent. Un retard du point d’allumage a traditionnellement été utilisé pour réduire le temps d’amorçage du catalyseur. Ceci est cependant associé à une augmentation de la consommation de carburant. Avec l’électrification des véhicules, la possibilité de chauffage électrique représente véritablement une alternative, tout particulièrement pour les véhicules hybrides. Cependant, la complexité des véhicules hybrides rend difficile l’évaluation des technologies de chauffage éventuelles ainsi que l’augmentation de la consommation de carburant associée ; il est aussi difficile de comparer ces résultats à ceux des solutions traditionnelles. Cette étude évalue l’installation d’un catalyseur chauffé à l’électricité dans un véhicule hybride, équipé d’un moteur au Gaz Naturel (GN. L’effet du chauffage sur le temps d’amorçage et la consommation de carburant est déterminé en utilisant des techniques d’analyse issues de la commande intégrée du groupe motopropulseur. L’importance de cette approche intégrale est illustrée par un cas exemplaire : l’impact d’une stratégie avec chauffage électrique sur la consommation de carburant et sur l’amélioration de l’efficacité de conversion catalytique est comparé à celui d’une stratégie de retard du point d’allumage. Au cours de cette comparaison, données de simulation et d’analyse ont été combinées, créant la base de développements de commandes futurs pour une stratégie d’amorçage adaptée.

The gas-fired boiler transformed from a conventional apparatus into the current high efficiency boiler. Will the high efficiency electricity boiler be the next breakthrough technique? The electrical and gas heat pumps are fully developed techniques, but this does not apply to their use in Dutch single-family dwellings [Dutch] De ontwikkeling, marktintroductie en toepassing van nieuwe technieken verloopt vaak volgens een S-vormige curve. De gasketel transformeerde van conventioneel toestel naar de huidige hr-ketel. Is de hre-ketel de volgende doorbraaktechniek? De elektrische en de gaswarmtepomp zijn uitontwikkelde technieken, maar nog niet voor de toepassing in een Nederlandse eengezinswoning.

    Micro gas turbines are a new technology for cogeneration with capacities of less than 300 kW{sub el}. Owing to the high heat level of up to 650 degrees centigrade, this is a promising technology for small and medium-sized industrial organisations who need process heat and have a low electric base load power consumption. A potential is viewed especially in process steam production and in direct drying. However, as the economic efficiency depends on the process boundary conditions, the project comprised the development of calculation tables to support the decision finding process. (orig.)

    Full Text Available The objective of this study is to evaluate the feasibility of an aqueous process for the biorefinery of sunflower whole plant using a co-rotating twin-screw extruder. Traditionally, aqueous extraction of oil is looked upon as an environmentally cleaner alternative technology to the solvent extraction (Rosenthal et al., 1996 and the twin-screw extruder carries out three essential unit operations continuously: conditioning and grinding of whole plant, liquid/solid extraction and liquid/solid separation. Wringing out the mixing is favoured thanks to the stalk fibers. However, drying of the cake meal is not optimal and lixiviation of cotyledon cells within the seed is incomplete. Extraction efficiency depends on the operating conditions: screw rotation speed, input flow rates of whole plant and water. In best conditions, oil yield is 57% and residual oil content in the cake meal is 14%. These conditions lead to the co-extraction of proteins, pectins and hemicelluloses. Protein yield is 44% and residual protein content in the cake meal is 7%. Oil is extracted in the form of two oil-in-water emulsions stabilized by phospholipids and proteins at interface. An aqueous extract containing part of the water-soluble constituents from whole plant, mainly proteins and pectins, is also generated. As a mixture of fibers and proteins, the cake meal can be moulded by thermo-pressing. Panels have promising mechanical properties in bending.

    Goal of the R and D project was the development of miniaturized HTSC resonators and filters. The work was divided into two main packages: ({alpha}) Systematic investigations of thin film samples, manufactured by partners of the common project as well as the development of characterization methods. ({beta}) Considerations of all relevant topics related to the design and manufacturing of high power filters with given specifications. The power handling capability of thin films is the most challenging issue in film production. A large variation in film quality could be observed that can cause problems in the realization of HTSC components. Employing the introduced concept of edge current free disk and ring resonators, high power HTSC filters can be realized with an improvement of 400 in power handling capability compared to other HTSC resonator types. During optimization of the unloaded quality factor, dielectric losses were identified to be the limiting factor. Two-pole, four-pole Chebyshev and four pole elliptic filters were developed and characterized and showed low loss and high power handling capability. (orig.) [German] Die Zielsetzung des F und E-Vorhabens war es, stark miniaturisierte leistungstaugliche Resonatoren und Filter auf der Basis von Hochtemperatur-supraleitenden Duennfilmen zu entwickeln. Die Arbeiten gliederten sich in zwei Teilbereiche: Einerseits wurden Methoden zur Hochfrequenz-Charakterisierung der zugrundeliegenden HTSL-Schichten entwickelt und systematische Untersuchungen an Proben schichtherstellender Verbundpartner durchgefuehrt. Andererseits wurden alle relevanten Teilprobleme zur Entwicklung hochleistungstauglicher Filter bearbeitet und entsprechende Problemloesungen entwickelt. Bei der Schichtherstellung stellte sich die geforderte Leistungstragfaehigkeit der HTSL-Schichten als besondere Herausforderung dar. Es wurde eine grosse Streuung der Filmqualitaet beobachtet, wodurch die Realisierung von Bauelementen erschwert werden kann. Die Realisierung leistungstauglicher Filter ist mit dem vorgeschlagenen Scheibenresonator-Konzept moeglich, welche eine um den Faktor 400 hoehere Energiespeicherung im Vergleich zu anderen HTSL-Strukturen erlauben. Bei der Optimierung der Leerlaufguete stellten sich dielektrische Verluste als begrenzender Faktor heraus. Es wurden sukzessive Zweipolfilter, 4-polig Tscherbyscheff-Filter und 4-polige quasi-elliptische Filter entwickelt und charakterisiert. (orig.)

    In this document we present a theoretical and experimental study which has been led to design a surface acoustic wave device for local characterisation (relatively to the wavelength) of isotropic or anisotropic materials. The device is based on a phased-array transducer of conical shape we have specifically designed for this purpose. It operates in the impulsive mode, in the frequency range of 1-5 MHz. In order to deduce mechanical properties of the material, it is possible to measure the surface wave characteristics (velocity, attenuation,...). Different methods for measuring the wave velocity have been developed taking advantage of from the phased-array technology. The originality of theses methods relies on the fact that the measures are performed without moving the transducer. Consequently, the device requires no additional mechanical system and it is quite compact. In addition, this shortens the characterisation process duration comparatively to the usually available methods (e. g. the V(z) technique). In the theoretical section of this study, a versatile model allowing to simulate in the time harmonic regime as well as in the transient regime, the transmitted field, the field reflected on isotropic or anisotropic planar samples and the output voltage for transducers of arbitrary shapes has been developed. The model has been applied to the phased-array conical transducer as well as to more classical transducers such as planar (rectangular) or focusing (spherically or cylindrically shaped) transducers. It predicts not only the geometrical contributions of the reflected field and signal but also the leaky contributions related to the surface acoustic waves. (author)

    Full Text Available Pentadesma butter is still traditionally extracted starting from pretreated almonds by traditional techniques of heating. The aim of this work was to study the effect of the almonds post-harvest pretreatments on the physicochemical characteristics, the extraction yield and the quality of the Pentadesma butter. In addition, the effect of the various unit operations of the extraction technology on the quality of the extracted butter from pretreated almonds was studied. According to the same traditional process of extraction, two various butters of Pentadesma were extracted starting from almonds differing only by the post-harvest pretreatment applied (roasting or boiling. The color, the aspect and the breaking strength of the almonds were different. The butter extraction yield varied according to the pretreatment applied. The best yields (33.5 ± 4.1% were obtained from boiled almonds, but their transformation was more difficult than that of roasted. The analysis of the samples at different stages of the transformation allowed the appreciation of the effect of the almonds pretreatments on the acidity and the peroxide value variations at each unit operation of the butter extraction. The fatty acid composition and the tocopherol content of the two extracted butters varied with the almonds pretreatments. The roasted almonds provided a richer butter in stearic acid, a and d-tocopherols and less rich in oleic acid than that provided by the boiled almonds. The pretreatments allowed a total loss of the contained linolenic acid, b and dtocopherols in the butters and decreased the oleic acid and a- tocopherol contents. The physico-chemical characteristics of the Pentadesma butter varied according to the almonds pretreatments. Thus, it would be interesting to make a reasoned choice of the most suitable post-harvest pretreatment in order to obtain a butter with a good quality and an acceptable extraction yield.

    Full Text Available Cet article présente un projet d’outil informatique destiné au travail en autonomie de la grammaire espagnole et s’adressant à des étudiants non spécialistes. En complément des cours et des différentes aides déjà mises à leur disposition, cet outil (qui offrira la possibilité de suivre des parcours d’apprentissage requérant différents degrés d’autonomie aura pour objectif d’aider les étudiants à acquérir ou à renforcer une partie des savoirs déclaratifs nécessaires à la réalisation d’un certain nombre de tâches langagières lors des cours présentiels. Le support informatique présente certains avantages par rapport à d’autres supports : par exemple la mise en place d’une série d’aides et de rétroactions formatives et personnalisées, qui sont susceptibles de faciliter cet apprentissage en autonomie. Après une présentation de quelques aspects psycholinguistiques qui ont servi d’appui à notre réflexion théorique, nous exposerons brièvement le cadre d’enseignement et les raisons qui nous ont conduits à la conception de cet outil, et nous évoquerons la place qu’il peut occuper dans un système d’enseignement/apprentissage ; puis nous décrirons son fonctionnement (parcours et étapes prévus pour l’apprentissage. Nous décrirons enfin la mise en place d’un dispositif restreint à la conjugaison espagnole qui, bien que comportant certaines limitations, nous a permis d’évaluer l’accueil de ce genre d’outil par les étudiants ainsi que l’utilisation qu’ils en faisaient.This article presents an Internet site for non-specialist students working on Spanish grammar, designed to encourage their autonomy. The Internet site is intended as a complement to regular classes and to the conventional tools already made available to these students. By offering a choice of learning paths in which learner autonomy is involved in several different ways, the designers seek to help students to acquire or to reinforce aspects of the declarative knowledge that they need to have mastered in order to perform language tasks during regular classes. In comparison to conventional media (such as books, an Internet site allows the provision of clues and formative individualized feedback in order to facilitate autonomous learning. Following the presentation of some of the psycholinguistic aspects upon which our theoretical reflections are based we briefly describe the learning context and explain the reasons that led us to imagine this tool, then we specify the potential function of such a tool in the educational and learning system. Having illustrated the way this tool could be used (through learning paths and stages, we finally describe the implementation of a test version of the tool, limited to conjugation learning and practice. We conclude that in spite of its limitations, this Internet site has allowed us to determine how the learners perceive such a tool and how they use it.

    Data acquisition and interpretation of LWD logs (''logging while drilling'') in highly inclined boreholes in new red sandstone have proved this to be a reliable alternative to conventional wireline measurements in assessing porosity and saturation. The contribution presents the results of the first measurements made in Germany using this method, which are compared with conventional wireline logs and drill core data. The LWD technology is superior in difficult boreholes and less costly if no conventional logs are made. Another advantage is the fact that the deposit is analyzed in the ''virgin'' state, i.e. before deep invasion by drilling, flushing and other invasive operations. [German] Die Datenakquisition und Interpretation von LWD (''logging while drilling'')-Messungen in hochgeneigten Rotliegend-Bohrungen haben gezeigt, dass es sich hierbei um eine zuverlaessige Alternative zu konventionellen Wireline-Messungen hinsichtlich der Porositaets- und Saettigungsbestimmung handelt. In diesem Beitrag werden insbesondere die Ergebnisse der ersten in Deutschland erfolgreich durchgefuehrten Messungen mit dem Sonic-LWD in tiefen 5 7/8{sup ''} Bohrloechern dargestellt und mit konventionellen Wireline-Logs und Kerndaten verglichen. Die operationellen Vorteile des LWD gerade in bohrtechnisch schwierigen Bohrungen wurden in der Praxis bestaetigt; Kostenvorteile sind vor allem dann gegeben, wenn auf konventionelles Loggen verzichtet wird. Ein weiterer Vorteil der echten ''Real Time''-LWD-Messungen ist zudem die Erfassung der petrophysikalischen Messungen im nahezu ''jungfraeulichen'' Zustand der Lagerstaette, d.h. bevor durch tiefe Invasion von Bohrspuelung und andere Traegerschaedigungen die Ergebnisse verfaelscht werden koennen.

  14. Theory and Practice of a New Class of Equipment for Separation of Particulates from Gases: the Turbulent Flow Precipitator Le précipitateur turbulent : un nouveau type de dispositif de séparation de particules présentes dans un courant de gaz. Théorie et technologie

    Directory of Open Access Journals (Sweden)

    Dullien F. A. L.

    2006-12-01

    Full Text Available The main classes of separators of particulates from gases comprise inertial separators, filters, (wet scrubbers and electrostatic precipitators, each of which technique has its proper niche and each has its advantages and its disadvantages. In the present paper a new class of equipment, the turbulent flow precipitator (TFP for gas cleaning is described that, though at the present only in its infancy, is rapidly gaining popularity because it has some advantages over each and every known type of separator and it has very few limitations. TFPs are far more efficient for the removal of fine particles than inertial separators, unlike filters they do not plug up, they do not present secondary disposal problems and they require less maintenance (and are less expensive than electrostatic precipitators. They can be very efficient also in the submicron range of particle size and there are no practical limitations as far as high temperatures and/or corrosive atmospheres are concerned. They are equally suitable for the removal of solid and liquid particles from gases. Turbulent flow precipitators work on the principle of turbulent eddy penetration into deep regions where there is no net flow, where the eddies die out and where the fine particulates carried by the eddies deposit on collector surfaces. TFPs comprise two well defined regions:- straight, uniform and unobstructed flow passages in which the gas carrying the suspended fine particulates is passed in turbulent flow;- and adjacent collection regions where there is no net gas flow and where all of the separation of particles from the gas takes place. Hence, a TFP is a filter in which the separation of the particulates from the gas takes place outside the passages where the gas flows. Les principaux séparateurs de particules dans un courant de gaz existants sur le marché sont les séparateurs par inertie, les filtres, les laveurs et les électrofiltres. Chaque type de séparateur est destiné à une utilisation spécifique et possède des avantages et des inconvénients. Cet article décrit une nouvelle catégorie de dispositifs appliqués à la purification des gaz, les précipitateurs turbulents (FIT qui, malgré leur nouveauté, ont gagné rapidement en popularité parce qu'ils présentent des avantages par rapport à chacun des autres types de séparateurs ; ils ont aussi très peu de limitations. Les précipitateurs turbulents sont beaucoup plus efficaces que les séparateurs par inertie pour la séparation des particules très fines, ne se colmatent pas comme les filtres, ne posent pas de problème de traitement secondaire, exigent moins d'entretien et sont moins coûteux que les électrofiltres. Ils peuvent atteindre une efficacité élevée même en présence de particules submicroniques, et ils ne sont pas soumis à des contraintes liées aux hautes températures et/ou aux environnements corrosifs. Ils peuvent séparer aussi bien des particules solides que liquides contenues dans un courant de gaz. Le mécanisme de précipitation turbulente consiste à faire pénétrer les tourbillons d'un courant turbulent d'un gaz dans des cavités profondes, caractérisées par l'absence d'un courant net, où la turbulence se dissipe et où les particules fines emportées par ces tourbillons sont captées sur des surfaces collectrices. Tous les précipitateurs turbulents incluent deux zones bien définies : - des conduits droits, uniformes et non obstrués dans lesquels s'écoule le gaz turbulent, portant les particules fines en suspension ; - des zones adjointes collectrices dans lesquelles il n'y a pas d'écoulement net et où s'effectue la séparation des particules présentes dans le gaz. Ainsi, les précipitateurs turbulents sont des séparateurs dans lesquels les particules sont séparées en dehors du flux gazeux.

    Technology progresses made to reach new oil and gas resources (heavy crudes, buried deposits, ultra-deep offshore), to better exploit the available reserves (increase of the recovery ratio) and to reduce the costs will allow to enhance the hydrocarbon reserves and to durably extend the limits of the world energy supply. In a context where geopolitical uncertainties, high price rates and pessimistic declarations increase once again the public fear about petroleum reserves, the French institute of petroleum (IFP) wanted to make a status about the essential role that technology can play in this challenge. This document gathers the transparencies and articles presented at this press conference: how to increase and renew oil and gas reserves, technology advances and research strategy of IFP (O. Appert, J. Lecourtier, G. Fries); how to enhance oil recovery from deposits (primary, secondary and tertiary recovery: polymers injection, CO{sub 2} injection, steam injection, in-situ oxidation and combustion, reservoir modeling, monitoring of uncertainties); the heavy crudes (the Orenoque extra-heavy oil, the tar sands of Alberta, the heavy and extra-heavy crudes of Canada, IFP's research); ultra-deep offshore (the weight challenge: mooring lines and risers, the temperature challenge: paraffins and hydrates deposition, immersion of the treatment unit: economical profitability of satellite fields); fields buried beyond 5000 m (technological challenges: seismic surveys, drilling equipment, well logging, drilling mud; prospects of these fields); oil reserves: data that change with technique and economy (proven, probable and possible reserves, proven and declared reserves, three converging evaluations about the world proven reserves, reserves to be discovered, non-conventional petroleum resources, technical progress and oil prices, production depletion at the end of the century).

    One of the main challenges in the energy transition is to integrate the increasing based on volatile renewable energy generated power in market and network. Based on actual distribution networks in Emsland in the study presented below was investigated, what contribution an intelligent coupling of electricity and gas distribution networks by means of power to gas (PtG) systems can do to solve this challenge. The investigations have shown, among other things, that the network expansion costs in particular can be significantly reduced by the coupling when otherwise an oversizing would be done by discrete power grid expansion measures. [German] Eine der wesentlichen Herausforderung bei der Energiewende besteht darin, die zunehmend auf volatilen erneuerbaren Energien basierende Stromerzeugung in Markt und Netz zu integrieren. Anhand realer Verteilungsnetze im Emsland wurde in der im Folgenden vorgestellten Studie untersucht, welchen Beitrag eine intelligente Kopplung von Strom- und Gasverteilungsnetzen mittels Power-to-Gas (PtG)-Anlagen zur Loesung dieser Herausforderung leisten kann. Die Untersuchungen haben unter anderem gezeigt, dass durch die Kopplung die Netzausbaukosten insbesondere dann signifikant reduziert werden koennen, wenn andernfalls eine Ueberdimensionierung durch diskrete Stromnetzausbaumassnahmen erfolgen wuerde.

    A new direction of effective removing liquid from the gas wells and improving of traditional gas-lift technologies for oil wells considered in this report. This direction merges the advantages of traditional methods such as gas-lift, plunger lift and swabbing, and it wide the range of application. Such a technology importantly decreases capital costs to installing wellhead and submerged equipment (it does not require the stopping of a well, trip and special conversion of tubing). It is ecology safe and does require minimal exploitation costs. A new technology derived a name - 'Combigaslift'. Combigaslift is the process of lilting of liquid from wells, in which it occurs by gas is been moving non-hermetic plunger-valve divider by wire and hoist. During a heaving a gas upflow does not allow to drain liquid under the divider. Tests of Combigaslift were made in gas and oil wells of different diameters. (author)

    The production of clinker in the cement industry involve the formation of nitrous oxides, and the emission limits are becoming more stringent from year to year. The added up total NOx emissions from the European cement industry amounts at present approx. 450.000 Mg/year. As such it is high time for the decision to develop and implement a technology to reduce NOx-emissions. At present SCR technology which is implemented in the glass industry, waste incineration and power plants seems to be the best economical and ecological solution for cement industry. In the period time from 1997 to the end of 1999 pilot plant test work was carried out by the companies 'Solnhofer Portland Zementwerke AG' and 'mg Engineering Lurgi' in the cement plant in Solnhofen. The results of pilot plan test work show that NOx reduction rates above 90% with NH{sub 3} slip less then 5 vppm can be achieved. The results of the test work with different type of catalysts are discussed. Based on the results of the test work a suitable SCR-process for cement industry is developed. At present a High-Dust-SCR demonstration plant at 'Solnhofer Portland Zementwerke AG' with the help of German Federal Environmental Agency, UBA-Berlin, is under commissioning and going on stream.

    The fuel index method aims at the largest possible exploitation of conservation potentials in residential thermal energy supply. The introduction of a thermal quality standard for thermal energy systems lays the foundation in process engineering terms for a competition between environment-friendly thermal energy supply and thermal insulation, with the aim to save energy and cost. Using higher-grade thermal energy at higher cost than current energy costs is approved of if its use involves an ambitious conservation aim. In this way, particularly rational energy techniques are promoted. (orig.)

    The energy consumption of buildings caused by air conditioning is high. The main reason is the using of refrigeration machines for dehumidification under the dew point. A reduction of the energy consumption is possible in case of using of desiccant dehumidification. A desiccant cooling air handling unit realizes the dehumidification by desiccants. Further more a heat recovery wheel and a humidifier are necessary. In the framework of the project the desiccant wheel and a high-pressure humidifier are investigated. A refrigeration machine was installed only for theoretical investigations. The investigation was done in the theoretical and experimental way. A new simulation model was developed. The measurement values are used for the verification of the mathematical simulation. In the framework of the project the performance characteristics of the desiccant wheel and the humidifier are optimized. As a result the regeneration temperature is now lower than at the beginning of the work. The humidifier capacity is in the same range at lower fresh water consumption. The components of the desiccant cooling air-handling unit were optimized according their performance characteristic. For the company Klingenburg the market chances will increase in case of more applications. (orig.) [German] Die Klimatisierung von Gebaeuden ist in aller Regel mit einem grossen Energieaufwand verbunden. Hauptursache dafuer ist die Verwendung der Entfeuchtung durch Taupunktunterschreitung unter Nutzung von Kaeltemaschinen. Eine Verringerung des Energieaufwandes ist nur durch Einsatz der sorptiven Luftentfeuchtung moeglich. Eine DEC-Klimaanlage realisiert die Luftentfeuchtung mit Hilfe der Sorption. Sie setzt sich aus verschiedenen Komponenten zusammen. Im Rahmen des Forschungsvorhabens wurden besonders der Sorptionsregenerator und der Kaltdampfgenerator sowohl experimentell als auch theoretisch untersucht und optimiert. Als ergaenzende Systemkomponente kommt die Kaeltemaschine hinzu, die jedoch

    Several theoretical investigations have shown that Stirling refrigerators could be a promising alternative for refrigeration at 'near-ambient' temperatures (above -40 C). These theoretical statements shall be validated in an actual research project by measurements taken from a Stirling refrigerator that is optimised for this range of temperature. In this paper first measurement results of this new developed Solo 161 Stirling refrigerator will be presented. Problems are investigated by detailed measurements. Possible improvements are described. (orig.) [German] Verschiedene theoretische Untersuchungen haben gezeigt, dass Stirling-Kaeltemaschinen eine interessante Alternative fuer die Kaelteerzeugung im sog.

    A planning tool for the thermal characteristics of integrated PV modules was to be developed and validated by measurements which provides U and g values as well as heating and cooling loads of such external wall or roof elements. In a cooperative project with medium-sized producers of PV wall systems, two different wall systems (i.e. insulating glass and ventilated warm external walls) were analyzed. [German] In dem Forschungsvorhaben sollte ein messtechnisch validiertes Planungswerkzeug fuer die thermischen Kennwerte von gebaeudeintegrierten Photovoltaikmodulen entwickelt werden, welches Bauteilkennwerte (U- und g-Werte) sowie moegliche Heiz- und Kuehllasten solcher Fassaden- oder Dachsysteme liefert. Durch die Zusammenarbeit mit mittelstaendischen PV-Fassadenherstellern sollten zwei Fassadensysteme - Isolierglasverbund und hinterlueftete Warmfassade - an konkreten Projekten messtechnisch erfasst und analysiert werden.

    The first part of the research project was titled ''energy-optimized recuperative braking''. In this part, several braking strategies, especially those for use in electro vehicles which in addition to the mechanical brakes of the vehicle also incorporate the electrical drive into the brake system were compared with the support of a simulation model and evaluated. The paper reports both on the simulation model used and on the possibilities of saving energy which can be achieved using the various braking strategies for differing driving cycles. In the second part of the research project, ''energy-optimized charging of traction batteries'', possible methods of charging traction batteries of electro vehicles are shown and assessed with regard to the battery efficiency under various conditions of application. [German] In dem unter der Ueberschrift 'Energieoptimiertes rekuperatives Bremsen' laufenden ersten Teil des Forschungsvorhabens wurden verschiedene und speziell fuer den Einsatz im Elektrofahrzeug entworfene Bremsstrategien, die neben den mechanischen Bremsen des Fahrzeugs auch den elektrischen Antrieb in das Bremssystem einbeziehen, mit Hilfe eines Simulationsmodells verglichen und bewertet. Im Bericht werden sowohl das verwendete Simulationsmodell erlaeutert als auch die energetischen Einsparmoeglichkeiten, die sich mit den verschiedenen Bremsstrategien fuer unterschiedliche Fahrzyklen erzielen lassen, aufgezeigt. Im zweiten Teil des Forschungsvorhabens ('Energieoptimiertes Laden von Traktionsbatterien') wurden moegliche Ladeverfahren fuer Traktionsbatterien von Elektrofahrzeugen aufgezeigt und hinsichtlich des Batteriewirkungsgrades bei unterschiedlichen Einsatzbedingungen beurteilt. In die Untersuchungen waren Blei-, NiMH-, NaNiCl{sub 2}- und Lithium-Batterien eingeschlossen. (orig.)

    In 1996 the two large heat storage tanks in Hamburg-Bramfeld (4,750 cubic metres) and Friedrichshafen-Wiggenhausen (12,000 cubic metres) were built out of concrete with an inner stainless steel lining. This was a big step towards economic efficiency. The research project ``Tight sealing of pit water storage tanks made out of pre-stressed concrete`` was launched by the BMBF in order to show that the concrete construction will not only bear loads but also ensure sealing. Building costs for underground hot water storage tanks could then be reduced by at least 25%. The first results of this research project are presented. The paper also contains recommendations for the further development of heat storage tanks built with pre-stressed concrete. (orig.) [Deutsch] Im Jahre 1996 wurden die beiden grossen Waermespeicher in Hamburg-Bramfeld mit einem Volumen von 4.750 m{sup 3} und in Friedrichshafen-Wiggenhausen mit 12.000 m{sup 3} aus Beton mit innenliegender Edelstahlauskleidung fertiggestellt. Mit dem Bau dieser beiden Grossspeicher konnte ein richtungsweisender Schritt hin zur Wirtschaftlichkeit gemacht werden, wie man es in Studien vor 15 Jahren nicht fuer moeglich hielt. Mit dem BMBF - Forschungsvorhaben `Dichte Heisswasser - Waermespeicher aus Hochleistungsbeton` soll gezeigt werden, dass das Betontragwerk nicht nur Lasten abtragen sondern auch die Funktion der Abdichtung uebernehmen kann. Damit sollen die Baukosten fuer unterirdische Heisswasser-Waermespeicher um mindestens 25% gesenkt werden. Es werden die ersten Ergebnisse dieses Forschungsvorhabens mitgeteilt und Empfehlungen fuer die weitere Entwicklung von Waermespeichern aus Hochleistungsbeton gegeben. (orig.)
