    In the key project 'EDISON', new technologies for electric power supply are investigated systematically. This comprised the development of mathematical models for commercial planning software (NETOMAC) for different decentral power generation systems like cogeneration systems, wind power systems, PV systems and fuel cells. The models will provide integration scenarios including sites for optimal network integration, optimisation of network operation, and network feedback effects. Prior to the start of the project, the available planning software did not include such models, so that the effects of decentral power generation and storage systems in electric power supply grids could not be investigated. (orig.) [German] Im Leitprojekt 'EDISON' wird der Einsatz neuer Technologie in elektrischen Energieversorgungsnetzen systemtechnisch untersucht. Dafuer werden sowohl fuer verschiedene Speicher wie Batteriespeicher, als auch unterschiedliche dezentrale Erzeugungseinheiten wie BHKW, Windkraftanlagen, Photovoltaikanlagen und Brennstoffzellen mathematische Modelle fuer uebliche Planungssoftware (NETOMAC) erarbeitet. Mit den Modellen sollen Einsatzszenarien fuer diese Betriebsmittel abgeleitet und anhand dynamischer Simulationsrechnungen Standorte der optimalen Netzanbindung, die Optimierung des Netzbetriebs und Netzrueckwirkung untersucht werden koennen. Vor Beginn des Projektes fehlten entsprechende Modelle in vorhandener Planungssoftware, so dass die Wirkung von dezentralen Erzeugern und Speichern in elektrischen Energieversorgungsnetzen nicht untersucht werden konnte.

    } emissions to be established until 2020, as well as the use of CO{sub 2} as a raw material (e.g. in the form of methane or in algae reactors) [cf. Federal Government, 2010, p. 20]. [German] In der vorliegenden Arbeit wird in Form einer Systemanalyse untersucht, inwiefern eine Kombination der drei Bereiche energetische Biomassenutzung, Kraft-Waerme-Kopplung (KWK) und CO{sub 2}-Sequestrierung (CCS - Carbon Capture and Storage) grundsaetzlich moeglich und sinnvoll ist. Unter dem Begriff CO{sub 2}-Sequestrierung wird in dieser Arbeit die Prozesskette aus CO{sub 2}-Abscheidung, CO{sub 2}-Transport und CO{sub 2}-Speicherung verstanden. Waehrend die Nutzung von Biomasse in Heizkraftwerken bereits gaengige Praxis darstellt, befindet sich die CO{sub 2}-Sequestrierung (auf Basis fossiler Energietraeger) im Forschungs und Entwicklungsstadium. Eine Kombination von CCS mit Biomasse ist bislang wenig, eine Kombination mit Heizkraftwerken gar nicht untersucht worden. Die beiden Techniken der energetischen Biomassenutzung und der KWK stellen in den Planungen der deutschen Bundesregierung feste Groessen im Energiesystem der Zukunft dar: Nach dem Leitszenario des Bundesumweltministeriums soll die Stromerzeugung aus Biomasse bis 2020 gegenueber 2008 nahezu verdoppelt werden. Gleichzeitig soll die in KWK erzeugte Waerme verdreifacht werden [vgl. Nitsch und Wenzel, 2009, S. 10]1. Parallel dazu soll die CCS-Technologie bis 2030 in der Haelfte aller deutschen Kohlekraftwerke eingesetzt werden [vgl. Krassuki et al., 2009, S. 17]. Auch die Kombination aus Biomasse und CCS stellt fuer die deutsche Bundespolitik eine perspektivisch denkbare Option dar [vgl. Bundestag, 2008b, S. 4]. Darueber hinaus werden der CCS-Technologie zukuenftig sehr gute Exportchancen fuer die deutsche Wirtschaft eingeraeumt [vgl. Bundesregierung, 2010, S. 20]. Die Kombination von Biomasse-Heizkraftwerken mit CCS bietet ueber die CO{sub 2}-Neutralitaet hinaus die interessante Moeglichkeit, als zukuenftiges Klimaschutzinstrument

    The efficiency of a combined power/heat plant is treated in an example relating to a gas turbine. An important prior condition for optimum planning of a combined power/heat plant is assessment of the current position in addition to a demand analysis. Constituting a vital planning instrument for the process are systematic annual continuous curves in respect of electricity and heat. Aided by a PC software program it is possible, on the basis of a few key figures, to establish whether a detailed study is able to bring about any economical solution. In addition, a primary-energy and emission balance-sheet is compiled illustrating the advantages to be gained from combined power/heat systems of relevance to the environment. A sensitivity analysis shows main influential factors exercised on the efficiency of the gas turbine project. As might be expected, the greatest influenc eon profitability comes from the electricity proceeds, the price of fuel and capital costs. Finally, different financing models for combined power/heat plants are discussed along with a price safeguarding method. (orig.) [Deutsch] Die Wirtschaftlichkeit einer KWK-Anlage wird am Beispiel einer Gasturbine erlaeutert. Wichtige Voraussetzung fuer die optimale Planung einer KWK-Anlage ist die Bestandsaufnahme mit Bedarfsanalyse.

Mit Hilfe eines PC-Programms kann anhand weniger Eckdaten festgestellt werden, ob eine Detailbetrachtung zu einer wirtschaftlichen Loesung fuehren koennte. Zusaetzlich wird eine Primaerenergie- und Emissionsbilanz erstellt, die die umweltrelevanten Vorteile der Kraft-Waerme-Kopplung verdeutlicht.

    The North Rhine-Westphalian state government intends to increase the share of combined heat and power (CHP) generation to at least 25 % by 2020. Since 2013, the campaign ''CHP.NRW - Power Meets Heat'' (''KWK.NRW - Strom trifft Waerme'') of the EnergyAgency.NRW, is has been running on behalf of the NRW Climate Protection Ministry, to publicise this technology and to promote its expansion. The campaign accompanies the State Government's CHP Stimulus Programme. The EnergyAgency.NRW has organised companies and research institutions, associations and interest groups under the umbrella of ''CHP.NRW - Power Meets Heat'', aiming at co-ordinated and intensified activities in the field of combined heat and power generation. The target of the initial-project ''roadmap/CHP.NRW'' of the ''Virtual Institute / CHP.NRW'' is to develop a guideline for the application and optimisation of CHP-systems.

    Since the implementation of the EEG in Germany the biogas production becomes an independent branch of industry in the agriculture. At this time more than 90 percent of the biogas plants work with co-generation plant for heat and power with a thermal engine efficiencies of more than 50 percent. Because of the location in the rural area heat costumers with a continuous demand of heat over the whole year are rare. This research had a closer look how to use the heat of biogas production efficiently and also generating profit. The aim of the study was to use heat over the whole year, a profitable heat concept without counting the KWK-bonus and an added value on the farm. During the study the following concepts were analyzed: asparagus production using soil heating, drying equipment for different products, the production of fish in aquaculture, the poultry production and the heated production of tomatoes. The results showed different concepts using heat of biogas plants as efficient for farmers. However with only one concept the aims - to use the heat over the whole year, generating a profitable heat concept without counting the KWK-bonus, add an value on the farm - mostly can not be achieved. The combination of different heat concepts is necessary. In this analysis the poultry production in combination with the dryer can be considered as the most efficient concept. Bearing in mind the benefit which can be generated with a heat concept as well as the higher income and the higher technical efficiency of biogas plants operators should implement an individual concept for their heat.

    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.

    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.

    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.

    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.

    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.

    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.

    By means of the ETVS process, predominantly liquid organic residues can be converted into electrical energy and mineral ash decentrally, i.e. where they accrue. The process is exemplified with reference to sewage sludge. Sludge containing at least about 4 % dry residue is dewatered to the highest dry substance content possible. The obtained filter cakes are indirectly dried in a fluidized-bed drier using internal process waste heat. Then the organic sewage sludge constituents are gasified in an atmospheric fluidized bed system. The cleaned product gas is used to generate power in a cogeneration power plant, meeting the sewage treatment plant's in-house power demand. The ETVS process is self-sufficient in terms of thermal energy requirement from an initial dry substance content of the filter cake > 40 %. Incineration is a means of disposing of sewage sludge in accordance with the boundary conditions for sewage sludge disposal from 2005, laid down in the technical code on municipal waste. Combining the ETVS process with modern biological treatment stages makes for a substantial cut in the construction and operating cost of sewage treatment plants. (orig.) [German] Mit dem ETVS-Verfahren koennen ueberwiegend fluessige biologische Reststoffe dezentral, d.h. an der Anfallstelle in eigennutzbare elektrische Energie und mineralische Asche umgewandelt werden. Das Verfahren wird am Klaerschlamm beispielhaft dargestellt. Der Klaerschlamm wird ab einem Trockensubstanzgehalt von ca. 4%TR auf moeglichst hohe Trockensubstanzgehalte entwaessert und die dabei erzeugten Filterkuchen mit internen Prozessabwaermen in einem Wirbelschichttrockner indirekt getrocknet. Die organischen Bestandteile des Klaerschlammes werden anschliessend in einer ebenfalls atmosphaerischen Wirbelschichtanlage vergast. Der mit dem gereinigten Produktgas in einer KWK-Anlage erzeugte Strom wird zur Deckung des Eigenbedarfs der Klaeranlage verwandt. Durch die Veraschung liefert das ab einem

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...

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.

    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.

    Although cogeneration plants are operated with fossil fuels are not quite as environmentally friendly as EEG systems they have a much more favorable effect due to their high efficiency climate as conventional power plants. In the future this could can even improve with the aid of fuel cell technology. Therefore, they play for the transition to a safe and secure more efficient power supply conditions for a merger of cogeneration plants overall favorable, in particular because that no influence on the or the emission trading obligation of the plant operators has. However, the complete elimination of avoided network charges could be counterproductive. Just virtual power plants of cogeneration plants have an effect on a feed-in that the grid not charged, so fees for a decentralized feed in these cases can be justified. Also the development of cogeneration development within the framework of the newly introduced calls will have a major impact on the development of virtual power stations. [German] Zwar sind KWK-Anlagen, die mit fossilen Brennstoffen betrieben werden, nicht ganz so umweltfreundlich wie EEG-Anlagen, doch haben sie aufgrund ihres hohen Wirkungsgrades eine viel guenstigere Klimabilanz als konventionelle Kraftwerke. In Zukunft koennte diese sich mithilfe der Brennstoffzellen-Technologie sogar noch verbessern. Daher spielen sie fuer den Uebergang zu einer sicheren und klimafreundlicheren Stromversorgung eine wichtige Rolle. Die Bedingungen fuer einen Zusammenschluss von KWK-Anlagen sind insgesamt guenstig, insbesondere weil jener keinen Einfluss auf die Foerdersaetze oder die Emissionshandelspflicht der Anlagenbetreiber hat. Allerdings koennte die vollstaendige Abschaffung vermiedener Netzentgelte kontraproduktiv sein. Gerade virtuelle Kraftwerke aus KWK-Anlagen wirken auf eine Einspeisung hin, die das Netz nicht ueberfordert, sodass Entgelte fuer eine dezentrale Einspeisung in diesen Faellen durchaus eine Rechtfertigung haben.

    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.

    A method to balance CHP-units for use in households on an annual basis has been developed. Seasonal as well as intraday fluctuations of the CHP-units are accounted for in the model. The results of this new method were validated in a test facility for certain days. Together with experimentally obtained data from a CHP-unit, the potential for technical improvements and a more favourable operational mode can be derived from the model. (orig.)

    Due to declining wholesale prices for electricity, the profitability of base load power and heat generation plants decreases significantly. Therefore, concepts such as the increased use of electricity or natural plant flexibility have to be developed. The improved framework conditions by means of the amended Combined Heat and Power Act are helpful. When modernising plants, it is even possible under favorable conditions and with a good concept to fully refinance the investment on the CHP surcharges.

    Fuel cells are the most efficient technology to convert chemical energy into electricity and heat and thus they could have a major impact on reducing fuel consumption, CO{sub 2} and other emissions (NO{sub x}, SO{sub x} and particulate matter). Fired with natural or biogas and operated with an efficiency of up to 49 % a significant reduction of fuel costs can be achieved in decentralised applications. Combined heat and power (CHP) configurations add value for a wide range of industrial applications. The exhaust heat of approximately 400 C can be utilised for heating purposes and the production of steam. Besides, it can be also fed directly to adsorption cooling systems. With more than 110 fuel cell power plants operating worldwide, this technology is a serious alternative to conventional gas turbines or gas engines.

    The incresing number of decentral power generation systems requires new grid solutions, i.e. the so-called smart grids. One important function is the monitoring and control, e.g. of decentral PV, wind power and cogeneration systems. The data interfaces used are highly diverse and as a rule are taken from measuring and automation technology, i.e. they must be adapted to the data models and transmission procedures of remote control and guidance systems. A compact protocol gateway enables standardized control and diagnosis.

    The contribution starts by assuming a region as a business organisation; on this basis, the authors develop the idea of a regional value-adding chain with regard to regional power supply. After presenting the central actors and their manner of integration, the contribution discusses concepts for sustainable power supply as well as the central parameters of such a development in terms of quality of life, attractivity of the region, future success of technologies, and criteria of value-adding. Finally, the implementation of regional power supply with the aid of a so-called 'balanced scorecard' is explained, which involves balancing of the various perspectives of the process up to the establishment of the final regional power supply concept. Finally, the contribution briefly discusses co-operative models for the establishment of a regional power supply concept. (orig.)

    Full Text Available V současné hornické praxi patří mezi nejpoužívanější způsoby ochlazování prostorově uzavřených požářišť přirozené ochlazování, ochlazování dusíkem, ochlazování vodou a inertní pěnou a ochlazování recirkulací požárních zplodin. 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

    The Directive 2009/28/EG (RED) requires a minimum level of greenhouse gas reduction for biofuels to be marketed. Site-specific production conditions are not considered in default values, which are specified by RED for calculating the greenhouse gas emissions. However, calculations of regional and farm specific GHG balances in accordance to the method of ExpRessBio for the production of rape seed show a considerable range of GHG-emissions in CO{sup 2}-eq (25.2-43.6 g MJ{sup -1}). For the complete product system of decentralized rapeseed oil fuel production in Bavaria a GHG reduction of 58 % can be achieved. This is slightly higher than the default value of 57 % as specified in Directive 2009/28/EG. The reason for this is that the default value under Directive 2009/28/EG is based on an industrial oil production process whereas decentralized production leads to less GHG emissions. In comparison to the application of the energy allocation method the substitution method for the assessment of rape seed cake as protein feed leads to a distinct higher GHG reduction rate of 85%.

    Chapter 2 describes the worldwide increase of primary energy consumption, which is expected in coming decades and results in possible solutions of a decentralised energy supply that is mainly based upon renewable energy carriers and the use of cogeneration systems. Chapter 3 shows the characteristics of decentralised system components that have been investigated in the frame of this research work as well as the resulting model library to depict the operational performance of the individual components and their mutual influence. A detailed dynamic simulation of a complete fuel cell system based on a steam reformer including the concept of local and superordinate control circuits is presented in chapter 4. Chapter 5 includes the integrated concepts for the intelligent and adaptable management of complex decentralised energy systems as well as a description of their implementation. Apart from the applied metaheuristic optimization methods the adaptable fuzzy-system, used in this case, is presented. The components of the model library of decentralised system components (chapter 3), the dynamic simulation of a complete fuel cell system based on a reformer (chapter 4), as well as the intelligent and adaptable plant management (chapter 5) are used in chapter 6 to investigate the various decentralised energy systems. The investigation focuses in particular on a) the electricity supply of a one-family home based on photovoltaics including different storage technologies and an increasing degree of energetic independence; b) the operational performance of a wind park with 72 individual plants as well as the combination of flywheel mass storage and wind energy plant; c) the control concepts, which have been developed for a fuel cell test stand based on a steam reformer, and their effects on the operation of the individual components as well as their interaction; d) the use of the developed management modules for the flexible and adaptable operation of a cogeneration system for house energy supply. In chapter 7 the contributions in the frame of this research work for the operational simulation, design and management of decentralized energy systems are summarized. (orig.)

    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.

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.

    On the basis of thermodynamic modelling, efficient online systems can be constructed which provide multiple commercial uses for plant operation. Incipient failures are recognized earlier, so that countermeasures can be taken at an early stage and long-term maintenance measures can be planned. Performance can be optimised, and - last but not least - the multitude of processed data enables workflow analysis, e.g. for simplifying billing processes in secondary relational databases. Performance data are presented of two coal power plants with 350 MWel/250MWth and 450MWel/50MWth in which systems of this type have been in use for several years now. (orig.)

    The current decisions on the phasing out from the nuclear power in Germany show that in addition to the requirements of the policy the demands of the users play an increasingly important role with respect to acceptance, energy request and future energy demand. By implementing innovative, energy efficient and environmentally friendly technologies from the household sector through trade to industry, natural gas as a source of energy favourably can be used.

    2012-07-01

    The studies described in this book demonstrate that the co-combustion of household waste in small-scale combustion plants constitutes an alternative disposal concept which facilitates the operation of decentralised waste disposal and heat supply systems. The basic idea of the concept is the co-combustion of different waste fractions in common household logwood heating systems. The experiments performed have shown that this is technically feasible using currently available technology without further modification and that these plants are capable of combusting various waste fractions at low emission levels. Several co-combustion systems were compared with basic oil, pellet and logwood heating systems in both economic and ecological respects. For this purpose cost-effectiveness calculations and a life cycle assessment were performed and brought together in an eco-efficiency analysis. The results show that the most cost-effective and eco-efficient solution is achieved when the co-combustion system is operated for high energy yield and simultaneous reduction of incombustible fractions.

    In order to achieve the European Union objectives of increasing the share of energy from renewable sources and from combined heat and power plants, new distributed generation units with different supply characteristics will have to be integrated in the nearer future into the existing power supply system (medium and low voltage grids). The use of these new distributed power producers opens up whole new possibilities for optimizing the system integration which however do necessitate more advanced system management strategies. Therefore the main objective of the working group 'energy management and system strategies', within the thematic network 'Energie und Kommunikation', was to investigate a market compatible and integrated energy management consisting of specific resource scheduling for individual power producers and of dedicated load management concepts. With this background, the working group developed an advanced energy management concept for distributed generation units and loads and specified the corresponding communication requirements respectively.

    Due to deregulation and liberalisation of the power market and due to the opting out of the nuclear energy, the decentralized power supply increasingly gains in importance in comparison to the classical power supply. Thus, the entrepreneur who wants to engage in the decentralized power supply needs a management tool for conversion and supervision his strategy. A pertinent means for this already is the Dynamic Balanced Scorecard. By means of an evaluation of a simple balanced scorecard, the entrepreneur realizes his vision and strategy in order to determine the success-critical factors. These success-critical factors are related together in a causal chain. By this, the entrepreneur can recognize, what has to be done in order to act successfully on the market, and in order to secure the success on a long-term basis. The modelling of the Dynamic balanced Scorecard enables the examination of the corporate strategy, before it is implemented in the enterprise. Thus, the entrepreneur saves time and minimizes the corporate risk.

    Energy Technology Data Exchange (ETDEWEB)

    Sommerfeld, H.

    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.

    The current contribution of the German Energy Agency (Berlin, Federal Republic of Germany) reports on the present sale situation of bio methane on the coupled and uncoupled heating market. The contribution clarifies, why the existing support measures do not stimulate the demand for bio methane in the necessary order of magnitude. Without adjustment of the legal framework neither the considerable sales potentials can be established, nor the targets for the development of the biogas feeding can be achieved approximately. The low demand on bio methane led to a planning stop on the producer side. Direct need for action is required.

    The district heating based on combined heat and power is a transitional technology on the way to the supply of Germany with renewable energy. In the next years, this transitional technology can only be maintained and expanded when marketability is given. Therefore an appropriate combination has to be found from investment measures. Together with new aspects in the management strategy, these investment measures should significantly improve the marketability. The investment measures also aims to enable a primary energetic, appropriate combination of natural gas-based combined heat and power, renewable energy sources (solar thermal energy, ambient heat) and heat pump technology.

    The effects of the key flow, mixing and ignition parameters on the ignition process was investigated in near-practical conditions. It was found that the ignition energy can be minimized by careful selection of the electrode configuration and positioning near the burner. Further, a criterion was developed for developing characteristic fields and design specifications for gas burners. The FLUENT code can calculate the mixing, flow and turbulence situation of a burner. This, and plus the newly established ignition criterion, can support the development of characteristic fields and help to minimize the experimental expenditure. [German] Der Einfluss der wichtigsten Stroemungs-, Mischungs- und Zuendparameter auf die Zuendung wurde mit Hilfe gezielter experimenteller und theoretischer Untersuchungen unter industrienahen Bedingungen getestet. Hierbei konnte eine gute Uebereinstimmung zwischen den Messungen und Rechnungen erzielt werden. Die Ergebnisse haben gezeigt, dass durch eine geeignete Wahl der Elektrodenkonfiguration und der Elektrodenpositionierung im Brennernahbereich eine Zuendenergieminimierung erreicht werden kann. Gleichzeitig wurde ein Kriterium entwickelt, das zur Erarbeitung von Kennfeldern und Auslegungsvorschriften fuer Gasbrenner genutzt werden kann. Mit Hilfe des kommerziellen CFD-Programms FLUENT kann die Mischungs-, Stroemungs- und Turbulenzsituation eines Brenners numerisch berechnet werden. Mittels dieser Ergebnisse und unter Anwendung des ermittelten Zuendkriteriums kann die Erstellung von Arbeits- und Zuendkennfeldern fuer die Neuentwicklung bzw. Verbesserung von Industriegasbrennern unterstuetzt und somit der experimentelle Aufwand minimiert werden. (orig.)

    Heat-guided combined heat and power (CHP) plants often cause large compensation energy amounts, additional costs to the operator respectively and another burden on the parent network. The balance energy is caused by errors in the production forecast whose quality heavily depends on the heat load performance. This paper identifies the forecasting problems with heat-guided CHP and reveals how the accompanying cost and the network burden can be reduced.

    The authors lived for quite a long time in Wendland , the village of opponents of atomic energy at Gorleben. They regard the conflict on the issue of Gorleben and atomic energy as being located within the fundamental conflict existing between various ways of life: between the rather traditional region with the centralistic model of the atomic state and their hopes for decentralized ecological communities. They report on the practical development of this resistance and point out its forms of struggle which have to be proportionate to the atomic antagonist, friends and foes in the region as well as to their own requirements and objectives concerning an ecological and independent way of life.

    Against the background of energy policy and climate policy decisions, the decentralized power generation has gained in importance in Germany. Previous research activities on this topic mostly concerned with technical, legal, environmental and economic issues as well as potential analyses for certain forms of power generation. In contrast, the contribution under consideration deals with the organizational structures and governance structures of the decentralized power generation at local and regional level. In particular, it concerns the question to what extent the decentralized power generation results in the formation of localized production connections. In addition, it is about the importance of institutional framework as well as the role of regulatory, political and civil society actors who are affected by the distributed power generation.

    The dissertation presents the fundamentals of hydrogen gas processing and CO gas purification methods and, on this basis, develops a method for energetic modularisation of the gas treatment process. All process stages are modelled and analyzed on the basis of mass and energy balances. The theoretical discussion of solution methods for the balance equations of the various process stages is limited to the steam reforming and CO gas purification system. Parameters are defined for energetic assessment of the process variants. The method leads to the identification of energetically optimized process variants. Its main goal is the optimum utilisation of process-internal energy and mass flows. The graphic pinch method is a key component of the method presented; it is adapted to the exemplary process. [German] In der Dissertation wird, ausgehend von der Darstellung der Grundlagen der Wasserstoffgasaufbereitungs- und CO-Gasreinigungsverfahren, eine Methodik zur energetischen Modularisierung des Gasaufbereitungsprozesses entwickelt. Die Modellierung und Analyse der einzelnen Prozessstufen erfolgt auf der Basis von Masse- und Energiebilanzen. Die theoretische Darstellung der Loesungsmethoden fuer die Bilanzgleichungen der einzelnen Prozessstufen ist dabei auf das System Dampfreformierung und CO-Gasreinigung eingegrenzt. Parameter zur energetischen Bewertung der Prozessvarianten werden definiert. Die Methodik fuehrt zur Eingrenzung energetisch optimierter Prozessvarianten. Ihr Hauptziel liegt in der optimalen Nutzung prozessinterner Energie- und Stoffstroeme. Ein zentraler Bestandteil der Methodik ist die graphische Pinch-Methode.

    The German Federal Environmental Agency (Umweltbundesamt, UBA) has developed three radically different scenarios of a future electricity supply entirely based on renewable sources in Germany by 2050. This study investigates the technical and ecological feasibility for one of these scenarios, the ''Local Energy Autarky'' scenario, by means of computer based simulation with a high spatial and temporal resolution. The scope of this scenario is restricted to small-scale decentralized energy systems which satisfy their own power demand without being connected with each other or with outside suppliers, i.e. without electricity imports. Relying only on locally available renewable energy sources to cover the electricity demand, makes electricity storage a necessity within the simulation model. The model itself consists of different modules representing electricity demand (e.g. for households, commerce and industry), power generation of different renewable technologies, and meteorological data, such as solar irradiation, wind speed, and outside temperatures. Various basic assumptions were made with regard to future developments such as energy efficiency. The simulations were applied exemplarily to a rural community with a low population density and a town district (high population and building density), each with and without trade/industry and each at a location in northern and in southern Germany, which are representative of the different meteorological conditions affecting the power generation from renewable sources such as wind and solar. Several variations were applied to the system, e.g. with regard to the share of electricity powered private vehicles or the installed generation capacities per technology. The simulation results show that the electricity demand of private households plus the demand for a complete shift to (private) e-mobility can be covered by the assumed locally available potentials for photovoltaics and wind energy, but only for the rural community and with an immense amount of storage required. If compared to the northern location the location in south Germany requires additional effort concerning the installed capacity for both electricity generation as well as storage. With the given assumptions for this study, however, it is not possible at all to establish a self-sufficient electricity supply for the town district. This is also true for the rural community if the electricity demand for commerce and industry statistically corresponding to the number of inhabitants is taken into account. With respect to these results it can be concluded that besides a local renewable generation the national electricity transport network is an important component for achieving a 100 percent renewable energy supply in Germany. On the one hand the large-scale balancing between fluctuating renewable energy feed-in and load can be beneficial. On the other hand potentials will have to be tapped where they exist. Regions with ''excess potential'' such as north Germany with its high wind potentials will have to cater to regions with a ''shortfall'' such as the industrial centers of electricity consumption in southern and western Germany. Thus, the concept sketched in the ''Local Energy Autarky'' scenario may be a feasible option in particular cases under favorable circumstances. According to the findings in this study, however, it presents no viable alternative for a 100% renewables-based electricity supply, at least not for the whole of Germany. Nevertheless, local generation can contribute a substantial share to a power supply entirely based on renewable energy sources as shown in the UBA ''Regions Network'' scenario.

    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.

    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.

    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.)

    Chlorine is used in the synthesis of almost two thirds of all chemical products. Producing chlorine from salt by electrolysis is a very energy-intensive process. 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...

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

    Jolanta JAWORSKA

    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.

This thesis is a contribution to the effort to cover the need for radiation-tolerant SEU-robust (Single Event Upset) programmable components for application in high energy physics 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 {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.

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.

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.)

    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.

    Fundamentally, storage facilities may replace conventional grid building measures. The storage facility thus adopts the function as an additional load if a large decentralized supply is into the network is performed. The storage facility acts as a generating plant at high reference load when the storage facility is unloaded. In order to replace a network expansion optimally, the storage facilities are at least optimized decentralized such as the corresponding power generating plants. The required capacity of the storage facility depends on the case of application. When used as an alternative to the network expansion, relatively high capacities with 6 kWh per kW of the installed generation capacity are required. Due to the rarely occuring maximum input performance only a low energy turnover is achieved. Under current framework conditions and realities of the market storage facilities exclusively for this application currently can not operated economically. Combined use of storage facilities by customers, trade and standards of the grid operator could allow an economical operation with modified framework conditions and corresponding decline in prices of energy storage systems.

    experimental effort, a similarity-theoretical scaling was carried out while keeping all dimensionless parameters relevant to the internal gas circulation process constant. Although the experimental results presented in this article therefore require a correction due to some external, not correctly scalable friction and insulation losses, they nevertheless prove that the realization of such switchable systems for decentralized, demand-oriented energy supply of buildings in a practical size and performance class is possible. In coordinated operation of a larger number of such systems - e.g. via ripple control or network load-dependent power consumption tariffs and power feed-in tariffs - can respond by appropriate switching between the operating conditions on load fluctuations in the public grid and so valuable, short-term retrievable control energy can be provided. Furthermore, applications in the field of drive-independent air conditioning, heating and power supply of vehicles are conceivable.

    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.

  15. 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

    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.

    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.

    The paper presents a prediction of the developments in hard coal mining technologies both in Poland and in the world. The longwall and the room-and-pillar systems will be realised. In Poland longwall equipment must be made more reliable and be better monitored, and more use made of roof bolting and means of controlling methane and rockbursts. Methods of underground gasification of coal seams need further development to realise the potential of this resource at reasonable production cost and with minimal environmental impact. 38 refs., 6 figs., 4 tabs.

    District cooling systems with combined heat, cold and power generation may be an alternative for the refrigeration supply with medium-sized decentralized compression refrigerating machines or for the wide-spread application of split devices. The implementation of discontinuously available renewable energy sources can be much better transposed by means of such systems.

    The exponential growth of the data rate in future telecommunication networks, requires the use of new transmission ways. Optical based networks show great promise for replacing 'slow' electronics technology. Through the use of wavelength division multiplexing technique (WDM), it becomes possible not only to increase the data rate on the line (here, an optical fibre) but also to use new alloptical based network. One of the key devices in these architectures is the tunable spectral filter. The ...

    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.

    the analysis of PV systems of the different types addressed in the database are presented and discussed. (orig.) [German] Im Rahmen des Vorhabens wurde an den laufenden Arbeiten im Task II des 'Photovoltaic Power System Programme' (PVPS) der Internationalen Energieagentur (IEA) wesentlich mitgewirkt. Es ist eine zentrale Aufgabe des Task II, das Wissen ueber die Auslegung und das Betriebsverhalten von Photovoltaik(PV)-Systemen zu verbreiten und durch Ansprache geeigneter Zielgruppen die Markteinfuehrung der PV-Technologie voranzutreiben. Dabei stuetzt sich das Vorhaben auf die Erstellung und Aktualisierung einer dezentralen Datenbank, in der sowohl detaillierte Anlagedaten von realisierten PV-Anlagen als auch monatsaufgeloeste Betriebsergebnisse der vermessenen PV-Systeme gesammelt und aufbereitet werden. Ziel der Arbeiten ist es, Informationen ueber Energieertraege, Zuverlaessigkeit und Kosten von verschiedenen PV-Systemen aus der ganzen Welt bereitzustellen und Richtlinien fuer optimale PV-Anlagen in Bezug auf ihr Betriebsverhalten und ihre Auslegung zu entwickeln. Die dezentrale Datenbank auf PC-Basis wurde im ISFH erstellt und konfiguriert. Das Datenbankprogramm besteht aus dem Programm 'PVbase' und dem Programm 'PVreport'. Umfangreiche Softwarewerkzeuge erlauben die Selektion von PV-Anlagen, die graphische und statistische Aufarbeitung der relevanten Daten von PV-Anlagen und den Export von berechneten Jahresmittelwerten. Die Datenbank enthaelt derzeit mehr als 260 PV-Anlagen mit monatlichen Datensaetzen von ueber 600 Betriebsjahren. Neben den allgemeinen Informationen sind Angaben ueber die Art der PV-Anlage (Netzverbund, Insel- oder Hybridanlage), ihre Montageart, ihre verwendeten Komponenten und oekonomische Daten enthalten. Die Datenbank umfasst einen grossen Anteil weltweit realisierter PV-Anlagen mit installierter Messdatenerfassung. Der Nutzen der kontinuierlich verbesserten Datenbank liegt in der Verbreitung von Informationen

    With their high efficiency and modular structure, fuel cells are an attractive option for decentral power supply. An important component of decentral power supply systems is the power-electronic control element for supply of electric power from the fuel cell to the three-phase electricity grid. Control elements can be constructed of a unidirectional DC/DC converter with a current inverter connnected in series. The investigation focused on the development of the DC/DC converter with minimum constructional and control requirements and optimum adaption of the DC/DC converter to the characteristics of the fuel cell. (orig.) [German] Die Brennstoffzelle stellt mit ihrem hohen Wirkungsgrad und ihrem modularen Aufbau eine attraktive Option fuer die Verwendung in einem dezentralen Energieversorgungssystem dar. Eine wichtige Komponente des dezentralen Energieversorgungssystems sind die leistungselektronischen Stellglieder fuer die Einspeisung der elektrischen Energie aus der Brennstoffzelle in das dreiphasige Netz. Die leistungselektronischen Stellglieder koennen aus einem undirektionalen DC/DC-Wandler und einem nachgeschalteten Wechselrichter realisiert werden. Die Entwicklung des DC/DC-Wandlers mit einem moeglichst geringeren Bauelemente- und Steuerungsaufwand fuer diese leistungselektronischen Stellglieder und die Anpassung des DC/DC-Wandlers an die Eigenschaften der Brennstoffzelle war das Ziel dieser Arbeit.

    2001-07-01

    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.

  2. 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

    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)

    Die Brennstoffzelle hat aus technischer Sicht einen hohen Stand erreicht. Die PEMFC konnte ihre Zuverlässigkeit in einer Reihe von Nischenanwendungen, aber auch in Form erster mobiler und dezentraler Prototypen beweisen. Die SOFC und die MCFC konnten bereits in Anlagen von 100 kW und mehr in Erprobung gehen. Um jedoch wirtschaftlich konkur-renzfähig zu den etablierten Technologien der mobilen und dezentralen Energiewandlung zu werden, muss noch eine drastische Kostenreduktion sowohl beim Brennstoffzellen-Stack als auch bei den zu seinem Betrieb notwendigen Hilfsaggregaten erreicht werden. Für Fahrzeugantriebe muss außerdem eine Antwort auf die noch offene Treibstofffrage (Infrastruktur, H2-Erzeugung und H2-Speicherung) gefunden werden.

    In 2007, the Hospital Infantil Los Ángeles (HILA) in Colombia implemented a slightly-modified version of the WHO guidelines for the diagnosis and management of malnutrition during childhood. To evaluate the efficacy of the WHO-HILA protocol in children hospitalized with severe, chronic marasmus and kwashiorkor malnutrition (MS-KWK) in 2007 and 2008. In this descriptive retrospective study the records of 100 children hospitalized with MSKWK were initially evaluated. Of these, 30 fulfilled the inclusion criteria: children of both sexes with a primary diagnosis of MS-KWK. Patients with any chronic disease liable to cause malnutrition were excluded. Anthropometric parameters, clinical signs and biochemical indicators of malnutrition were assessed upon admission and again at discharge following application of the WHO guidelines. Univariate analysis was performed for each study variable; serum hemoglobin and albumin levels on admission and at discharge were compared, and data were subjected to bivariate analysis. Marasmus was diagnosed in 23.3% of children, kwashiorkor in 73.3% and marasmic kwashiorkor in 3.3%. The major clinical findings were: edema (70%), emaciation (40%), "flag sign" hair (42.86%), low serum albumin (93%) and anemia (80%). Thirteen children following the WHO-HILA protocol showed a significant nutritional status improvement (pmalnutrition. Implementation of this protocol should therefore be considered in all children´s hospitals in countries where this disease is prevalent.

    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.

    Even operators of industrial-scale power stations have good reasons to look into combined heat and power generation. CHP systems have a high thermal and electric efficiency, especially in case of optimized integration into the existing power station park of a public utility. Utilities can supply heat as well as electricity and thus improve customer loyalty by full-scale coverage of a locally limited market. The author presents activities for gaining strategic advances in the (niche) market for combined heat and power generation systems.

    Full Text Available Nowadays the mining companies use the Spatial Information System in order to facilitate data management, gathered during the mining activity. For these purposes various kinds of applications and software information are used. They allow for faster and easier data processing. In the paper there are presented the possibilities of using the ArcGIS system to support the tasks performed in the mining industry in the scope of the analysis of the influence of the mining tremors, induced by the longwall exploitation on the facilities construction sited on the surface area. These possibilities are presented by the example of the database developed for the coal mine KWK “Rydułtowy-Anna.” The developed database was created using ArcGIS software for Desktop 10. 1. It contains the values of parameters, specified for its implementation relevant to the analyses of the influence of the mining tremors on the surface structures.

  14. Technical and economical analysis of concepts for using the heat of biogas plants in rural areas

    International Nuclear Information System (INIS)

    Kaths, Friederike Annette

    2012-08-01

    Since the implementation of the EEG in Germany the biogas production becomes an independent branch of industry in the agriculture. At this time more than 90 percent of the biogas plants work with co-generation plant for heat and power with a thermal engine efficiencies of more than 50 percent. Because of the location in the rural area heat costumers with a continuous demand of heat over the whole year are rare. This research had a closer look how to use the heat of biogas production efficiently and also generating profit. The aim of the study was to use heat over the whole year, a profitable heat concept without counting the KWK-bonus and an added value on the farm. During the study the following concepts were analyzed: asparagus production using soil heating, drying equipment for different products, the production of fish in aquaculture, the poultry production and the heated production of tomatoes. The results showed different concepts using heat of biogas plants as efficient for farmers. However with only one concept the aims - to use the heat over the whole year, generating a profitable heat concept without counting the KWK-bonus, add an value on the farm - mostly can not be achieved. The combination of different heat concepts is necessary. In this analysis the poultry production in combination with the dryer can be considered as the most efficient concept. Bearing in mind the benefit which can be generated with a heat concept as well as the higher income and the higher technical efficiency of biogas plants operators should implement an individual concept for their heat.

    2001-07-01

    Decentralized energy systems is the major topic of this VDI report which contains the proceedings of the VDI conference on advanced energy conversion and application. The decentralized energy systems are in the focus because it is expected that they will gain in significance in the course of restructuring and liberalisation of the energy markets and growing commitment to greenhouse gas mitigation. The subjects of the papers are the cogeneration technology in general, and specific systems for combined generation of heat, power and cold,(CHPC systems), systems for renewable energy generation, industrial energy technology, and analysis and optimization of energy systems. The report is intended to serve as a source of guidance and reference for manufacturers and operators of decentralized energy systems, for decision-making on energy policy, and for the energy industry, counselling firms and regulatory/surveillance bodies, and members of universities involved in relevant research and development work.
