Dokumentiert die Ergebnisse des Fachprojekts "Einbingung von Frage-Antwort-Diensten in die Web-Suche", Wintersemester 2007/2008, Dept. Information, Hochschule für angewandte Wissenschaften Hamburg. Mit sozialen Suchdiensten - wie z.B. Yahoo Clever, Lycos iQ oder Mister Wong - ist eine Ergänzung zu den bisherigen Ansätzen in der Web-Suche entstanden. Während Google und Co. automatisch generierte Trefferlisten bieten, binden soziale Suchdienste die Anwender zur Generierung der Suchergebnisse in den Suchprozess ein. Vor diesem Hintergrund wird in diesem Buch der Frage nachgegangen, inwieweit soziale Suchdienste mit traditionellen Suchmaschinen konkurrieren oder diese qualitativ ergänzen können. Der vorliegende Band beleuchtet die hier aufgeworfene Fragestellung aus verschiedenen Perspektiven, um auf die Bedeutung von sozialen Suchdiensten zu schließen.

Von der Europäischen Rechtsgeschichte zu einer Rechtsgeschichte Europas in globalhistorischer Perspektive

Directory of Open Access Journals (Sweden)

Thomas Duve

2012-01-01

In den letzten Jahren sind im Zuge der Diskussion um postkoloniale Perspektiven auf die Geschichte, um Transnationale und Globalgeschichte, viele Grundlagen der traditionellen Europahistoriographie kritisiert und massiv erschüttert worden. Das wirft Fragen auch an die Europäische Rechtsgeschichte auf: Welches Europabild liegt ihr zu Grunde? Auf welchen intellektuellen und konzeptionellen Grundlagen beruht sie? Wie antwortet sie auf die Vorwürfe des Eurozentrismus, des epistemischen Kolonialismus, wie auf die Forderung, Europa zu ›provinzialisieren‹? Wie definiert sie das Verhältnis der Europäischen zur Transnationalen und Globalen Rechtsgeschichte? – Diesen und ähnlichen Fragen wenden sich die folgenden Überlegungen zu. Der Schwerpunkt liegt auf einer Auseinandersetzung mit der Tradition, ihren konzeptionellen Grundlagen und deren wissenschaftshistorischem Kontext (1. Teil, 1.–6.. Aus dieser kritischen Bestandsaufnahme und den Ergebnissen der Debatte um Globalgeschichte ergeben sich Ausgangspunkte und Aufgaben einer in Vielem auf den Leistungen der Disziplin aufbauenden, doch notwendigerweise auf einer anderen Konzeption beruhenden Rechtsgeschichte Europas in globalhistorischer Perspektive (2. Teil, 7.–11..

) durchgefuehrt. Die Bilddatensaetze wurden von 4 Untersuchern voneinander unabhaengig anhand des ILO-Klassifikationsbogens fuer Staublungenerkrankungen beurteilt. Ergebnisse: Die digitale Selenradiographie zeigte bei Thoraxuebersichtsaufnahmen im sagit-talen Strahlengang eine im Vergleich mit der analogen Technik gleichwertige Einschaetzung der Befunde anhand der ILO-Klassifikation. Die Bildqualitaet der digitalen Aufnahmen wurde im Vergleich zu der analogen Film-Folien-Kombination als signifikant besser eingestuft. Schlussfolgerungen: Der Einsatz der digitalen Selenradiographie fuehrt in der Diagnostik von Pneumo-koniosen bei den angewandten Bildverarbeitungsalgorithmen im Vergleich zur verwendeten analogen Film-Folien-Kombination bei besserer Abbildungsqualitaet weder zu einer Ueber- noch zu einer Unterbewertung der pulmonalen Veraenderungen anhand der ILO-Klassifikation. Daher kann die digitale Selenradiographie die verwendete analoge Film-Folien-Kombination in der Diagnostik von Staublungenerkrankungen gleichwertig ersetzen. (orig.)

Design of the intake and outlet areas of turbines; Gestaltung der Zu- und Abstroemung von Turbinen

Energy Technology Data Exchange (ETDEWEB)

Ruprecht, A. [Stuttgart Univ. (Germany). Abt. Numerische Stroemungsmechanik

1997-12-31

Especially in the case of plants with a small height of drop, efficiency can be substantially impaired. Moreover, an unfavourable design of the inlet area can result in operating problems because of instationary flow phenomena. Similar considerations apply to the draft tube and outflow area. Selected examples are chosen to demonstrate problems and propose improvements. As modelling demands too much effort in the case of small plants, the investigations are carried out using modern numerical flow calculation methods. As demonstrated, inlet and outflow areas can be economically designed using these methods even in the case of small hydro power stations so as to present favourable flow parameters. [Deutsch] Vor allem bei Anlagen mit kleiner Fallhoehe kann der Verlust betraechtlich sein. Darueber hinaus kann eine unguenstige Gestaltung des Einlaufbereichs durch instationaere Stroemungsphaenomene auch zu Problemen beim Betrieb der Anlage fuehren. Aehnliches gilt bei der Gestaltung des Saugrohrs und der Abstroemung. An ausgewaehlten Beispielen werden Probleme dargestellt und Verbesserungsvorschlaege aufgezeigt. Da bei kleinen Anlagen Modellversuche zu aufwendig sind, erfolgen die Untersuchungen mit modernen Methoden der numerischen Stroemungsrechnung. Es wird gezeigt, dass man mit diesen Methoden in der Lage ist, auch bei Kleinwasserkraftanlagen wirtschaftlich eine stroemungsguenstige Gestaltung von Zu- und Abstroemung zu erreichen. (orig.)

Zu einer inhaltsorientierten Theorie des Lernens und Lehrens der biologischen Evolution

Science.gov (United States)

Wallin, Anita

Der Zweck dieser Studie (zwecks Überblick siehe dazu Abb. 9.1) war zu untersuchen, wie die Schüler der Sekundarstufe II ein Verständnis von der Theorie der biologischen Evolution entwickeln. Vom Ausgangspunkt "Vorurteile der Schüler“ ausgehend wurden Unterrichtssequenzen entwickelt und drei verschiedene Lernexperimente in einem zyklischen Prozess durchgeführt. Das Wissen der Schüler wurde vor, während und nach den Unterrichtssequenzen mit Hilfe von schriftlichen Tests, Interviews und Diskussionsrunden in kleinen Gruppen abgefragt. Etwa 80 % der Schüler hatten vor dem Unterricht alternative Vorstellungen von Evolution, und in dem Nachfolgetest erreichten circa 75 % ein wissenschaftliches Niveau. Die Argumentation der Schüler in den verschiedenen Tests wurde sorgfältig unter Rücksichtnahme auf Vorurteile, der konzeptionellen Struktur der Theorie der Evolution und den Zielen des Unterrichts analysiert. Daraus konnten Einsichten in solche Anforderungen an Lehren und Lernen gewonnen werden, die Herausforderungen an Schüler und Lehrer darstellen, wenn sie anfangen, evolutionäre Biologie zu lernen oder zu lehren. Ein wichtiges Ergebnis war, dass das Verständnis existierender Variation in einer Population der Schlüssel zum Verständnis von natürlicher Selektion ist. Die Ergebnisse sind in einer inhaltsorientierten Theorie zusammengefasst, welche aus drei verschiedenen Aspekten besteht: 1) den inhaltsspezifischen Aspekten, die einzigartig für jedes wissenschaftliche Feld sind; 2) den Aspekten, die die Natur der Wissenschaft betreffen; und 3) den allgemeinen Aspekten. Diese Theorie kann in neuen Experimenten getestet und weiter entwickelt werden.

Schmid, Gerhard; Heppner, Winfried; Focht, Eva

In seiner 2007 erschienen Sammlung von Vorträgen und Essays beschäftigt sich Wolfgang Frühwald, mit der Frage "Wieviel Wissen brauchen wir?“ [1] Die Kernproblematik moderner Wissenschaft und Forschung sieht der Autor, emeritierter Ordinarius für Neuere Deutsche Literaturwissenschaft und von 1992 bis 1997 Präsident der Deutschen Forschungsgemeinschaft, einerseits in der zunehmenden Spezialisierung der Wissenschaftsbereiche, andererseits in der Gefahr der Abkoppelung der Naturwissenschaften von den Geisteswissenschaften. Wiederholt plädiert er dafür, über der rasanten Entwicklung beispielsweise in der Biologie und Physik, die historische, gesellschaftliche und besonders die ethische Dimension der Forschung nicht zu übersehen und fordert eine übergeordnete Theorie der Wissenschaft, die nur im Dialog zwischen den einzelnen Fachgebieten zu entwickeln sei.

Der deutsche Schriftsteller Thomas LEHR liest am 23. März 2006 aus seinem Roman '42', einem philosophischen Abenteuerroman über die Suche nach der Zeit, erzählt in einer funkelnden und souveränen Sprache. Eine Welt von vernichtender Schönheit und bizarren Schrecken wartet auf eine Besuchergruppe, die in der Nähe von Genf die unterirdischen Anlagen des Forschungszentrums für Teilchenphysik CERN besichtigt. Als sie um 12:47:42 wieder ans Tageslicht tritt, scheint ganz Europa in einen Dornröschenschlaf gefallen. Allein die 70 Besucher können sich noch bewegen. Monate und Jahre verharrt die Welt wie in einer riesigen dreidimensionalen Fotografie, bis ein wiederum schockierendes Ereignis die 'Chronifizierten' aus ihren physikalischen Spekulationen und seltsamen Lebensformen reisst.

Full Text Available Sexuelle Bildung ist und war schon immer eine umkämpfte Disziplin der Pädagogik. Dabei ist die aktuelle Erregung um diese als Reaktion auf die fortschreitende Pluralisierung von Lebensentwürfen und die Liberalisierung von Normen und Werten zu verstehen, auf die eine diversitätsbewusste Sexualpädagogik in ihren Konzepten Bezug nimmt, die aber von ultrakonservativen, fundamentalistischen und rechtsradikalen Gruppierungen angegriffen werden. Diese Gemengelage nehmen die Autor_innen zum Anlass, um ausgewählte in der Kritik stehende Inhalte einer sexualfreundlichen Bildung zu besprechen und die Argumentationsmuster der Kritiker_innen zu verdeutlichen. Damit trägt der Band zur (Re-Kontextualisierung und Versachlichung einer hochemotionalen Auseinandersetzung über sexuelle Bildung bei.

Jens F. Heiderich

2009-07-01

Full Text Available Stauffer legt eine hervorragende Studie zu ironischen Inszenierungen geschlechtsspezifischer Topoi vor. Literaturgeschichtlich präzise werden die Geschlechterverwirrungen im Fin de Siècle unter besonderer Berücksichtigung der Werke Annette Kolbs und Franziska zu Reventlows kontextualisiert und mit Hilfe eines eigens entwickelten methodologischen Ansatzes analysiert. Überzeugend kann Stauffer darlegen, dass den Ironisierungen der Femme fragile und der Femme fatale, des Décadents und des Dandy die Funktion zukommt, Geschlecht als Konstruktion zu enthüllen. Avant la lettre werde dadurch Judith Butlers Theorie der subversiven Performativität bestätigt. Für die Beschreibung der damit verbundenen Konstruktionsverfahren hält Stauffer allerdings den Begriff der Ironie für treffender als den von Butler u. a. favorisierten Begriff der Parodie.

Wie viel muss ich wissen, um global handeln zu können? Verantwortung für Weltarmut und das Problem der epistemischen Überforderung

Directory of Open Access Journals (Sweden)

Weber-Guskar Eva

2015-12-01

Full Text Available Was heißt es, sich in unserer globalisierten Welt als eine vollverantwortliche Person zu verstehen und zu verhalten? Einerseits scheint es richtig, dass wir global verantwortlich sind, d.h. dass wir auch gegen entferntes Leid etwas tun sollten; andererseits aber ist wegen vielfacher Überforderungsproblemen unklar ist, wie man diese Verantwortung tatsächlich übernehmen können soll – was wiederum dagegen spricht, dass wir diese Verantwortung berechtigtermaßen zuschreiben können. Um einen Aspekt dieses großen Themas zu behandeln, konzentriere ich mich in diesem Aufsatz auf den Anwendungsbereich von extremer Armut und argumentiere in folgenden Schritten. Zuerst spitze ich das Thema zu auf ein Problem, das Samuel Scheffler in diesem Zusammenhang konstatiert hat, nämlich einen Widerstreit zwischen dem, was Verantwortung unter den Bedingungen der Globalisierung bedeutet und dem, wie wir uns grundsätzlich als Handelnde zu verstehen gewohnt sind. Dann zeige ich erstens, dass dem Thema einer epistemischen Überforderung dabei entscheidendes Gewicht zugesprochen wird, zweitens jedoch, dass sich, genauer besehen, dieses Problem gar nicht in dieser Art stellt. Dafür schlage ich eine Analyse des Verantwortungsbegriffs vor, die es ermöglicht, Kriterien zu identifizieren, anhand derer gewisse Grenzen gezogen werden können, so dass die Zuschreibung der Verantwortung gerechtfertigt werden kann.

Full Text Available Durch die PädagogInnenbildung_NEU eröffnet sich derzeit die Chance, österreichweit in vier Verbundregionen in Kooperation zwischen Universitäten und Pädagogischen Hochschulen die Lehramtsausbildung für alle Schulstufen und Schultypen zukunftsweisend zu reformieren. Zu den Ansprüchen an das neue Studium gehört auch, dass es künftige LehrerInnen an die Schulen entsendet, die neben ihrer fachlichen Expertise mit aktuellen gesellschaftlichen Herausforderungen und Entwicklungen adäquat umgehen können. Die rasant voranschreitende Technologisierung und Digitalisierung unserer Gesellschaft gehört zweifelsohne zu diesen Herausforderungen. Die E-Learning-Strategiegruppe der österreichischen Pädagogischen Hochschulen (PHELS hat deshalb die aktuell vorliegenden Curricula und Curriculaentwürfe der Sekundarstufe Allgemeinbildung in den vier Verbundregionen einer kritischen Analyse hinsichtlich Medienbildung und digitaler Kompetenzen unterzogen − mit einem ernüchternden bis verheerenden Ergebnis: Es scheint nicht nur die historische Chance vertan, Medienbildung systematisch in der LehrerInnenausbildung und damit in den Schulen zu verankern, sondern durch die fehlende informatische Grundbildung laufen künftige Generationen auch Gefahr, auf zunehmend digitalisierten Arbeitsmärkten den internationalen Anschluss zu verlieren.

Das Hauptanliegen des Papiers ist, ein Paradigma für Probleme mit neuartigen Integrationsanforderungen für Forschung und Entwicklung in verteilten eingebetteten Echtzeitsystemen zu motivieren und vorzustellen, nämlich den Begriff Cyber-Physical Systems. Bei einer in letzter Zeit stark zunehmenden Anzahl von Realzeitanwendungen können ohne die Berücksichtigung solcher Forderungen keine praktisch brauchbaren Lösungen erwartet werden. Einige Anwendungsfelder werden angesprochen. Im Einzelnen werden dann für Elektroautos, die mit erneuerbaren Energien betrieben werden sollen, einerseits die Management-, verteilte Verhandlungs- und Verteilungsprobleme der benötigten Energie in einem bottom-up Ansatz gelöst. Andererseits wird als Teil unserer Projektarbeit die Bereitstellung von Reserveenergie für den allgemeinen Bedarf durch Autobatterien vorgestellt. Es zeigt sich, dass dies effizienter und wesentlich kurzfristiger in unserem verteilten Vorgehen geschehen kann als in traditionellen Verfahren.

Full Text Available Uta Fenske beschäftigt sich in ihrer Dissertation mit den Männlichkeitsentwürfen des klassischen Hollywoodfilms der 1950er Jahre. Die Historikerin blickt damit zurück in eine Ära US-amerikanischer Geschichte, in der soziokulturelle Umbrüche zu einer Erschütterung tradierter Männlichkeitsbilder, zu einem Krisendiskurs über den modernen Mann führten. Fenskes kulturwissenschaftliche Studie kann sich dabei aus zweierlei Sicht profilieren. Zum einen erweitert sie mit der unorthodoxen Wahl ihres Untersuchungsgegenstandes das geschichtswissenschaftliche Quellenkorpus. Zum anderen kann sie durch ihren Rekurs auf eine Vielzahl von Genres zeigen, dass die Hollywoodfilme der 1950er eine größere Fülle an Antworten auf die Krise anbieten als gemeinhin angenommen.

Der Gewalt ihre Freiheit - Der Horror-Film als jugendliches Wertekonstrukt

2010-06-01

Full Text Available Jugendliche Gewaltbereitschaft wird in der medienkritischen Diskussion nicht selten auf mediale Vorbilder zurück geführt. Anhand qualitativer Daten wird zum einen gezeigt, dass das Erkennen medialer Gewalt in Sprache und Handlung bildungsabhängig ist, zum anderen, dass Jugendliche nach eigenen Angaben aus sehr unterschiedlichen Gründen zur Gewalt bereit wären – etwa, um Freunde zu verteidigen. Besonders betrachtet werden dann Jugendliche, die gern Horrorfilme anschauen. Die Untersuchung zeigt, dass die Fans von Horrorfilmen eine Rezeptionshaltung einnehmen, die zwischen Angst-Lust und Distanz oszilliert. Es interessieren hier keine identifikatorischen Aspekte, sondern Jugendliche haben Spaß an den medialen Inszenierungen des Gruseligen. Jenseits medienmoralischer Warnungen plädiert der Beitrag – unter Verweis auch auf Rezeptionstheorien der Literaturwissenschaft – dafür, distanzierten Horror-Genuss als Spielform nicht zu überbewerten und ihn auch als Ausdruck elaborierter Lese- und Medienkompetenz zu verstehen. Whereas within media-critical discussions violence of teens is sometimes said to be produced by referent power of media, this paper presents empirical data which show that and how teens are able to assume a distance when viewing media violence in horror-films. What they feel is not empathy, but fun. Young people enjoy a kind of delightful horror for themselves and are able to step into distance while talking to peers about their impressions during reception. This way of “delightful horror” is not only a phenomenon of modern media reception but can be found in recent and established horror literature. In so far this article encourages a more relaxed way of judging young people’s media habits.

Przeciętne jednostkowe zużycie wody w okresie, kiedy realizowane są zajęcia dydaktyczne, wyniosło 29,3 dm3·d–1 dla studenta studiów stacjonarnych i 23,2 dm3·d–1 dla studenta studiów niestacjonarnych. W okresie wakacyjnym wskaźniki te są niższe i wynoszą odpowiednio 15,2 oraz 11,4 dm3·d–1. Wskaźniki te wyznaczono bez uwzględnienia zużycia wody w akademikach. Współczynnik nierównomierności dobowej dla całego kampusu wyniósł 1,54 i był zbliżony do współczynnika nierównomierności godzinowej, wynoszącego 1,52. Najwyższe miesięczne zużycie wody wystąpiło w czerwcu i było o 85% większe od najniższego, które wystąpiło w sierpniu.

In den einzelnen Beiträgen wird der Frage nachgegangen, ob die zunehmende Sichtbarkeit von Politikerinnen wie Angela Merkel, Christina Kirchner oder Ségolène Royal auch zu einer veränderten medialen Berichterstattung geführt habe. Analysiert werden nicht nur die mediale Präsenz von Politikerinnen im Vergleich zu ihren männlichen Kollegen, sondern auch die Gemeinsamkeiten und Unterschiede in den textuellen und bildlichen Darstellungsweisen. Der Band liefert aus der Perspektive der politischen Kommunikationsforschung einige interessante empirische Einzelanalysen.

Dies vor allem im Bereich der traditionellen Kern- und Grundlagen-Wissenschaft der neuzeitlichen Universität: der Philosophie und der historisch aus ihr erwachsenen Psychologien. Seit einigen Jahren ist in den USA in der Tat eine Entwicklung im Gang, welche die Einseitigkeiten des nominalistisch-subjektivistischen Paradigmas der „Postmoderne“, welches aus ideengeschichtlicher Sicht die Epoche zwischen 1979 und 2001 geprägt hat, um einen neuen geistigen Objektivismus ausgleichen und beide zu einem neuen, „subjektiv-objektiven“ Paradigma integrieren will. Diese Entwicklung findet ihren Ausdruck in drei exemplarischen Avantgarde-Strömungen, die im vorliegenden Beitrag vorgestellt sowie auf Charakteristiken und Wechselbeziehungen untersucht werden. Dabei erweist sich, dass die heutige ideengeschichtliche Avantgarde der USA in Kernterminologie, historischer Kontinuität und Ausrichtung stark pazifisch-asiatisch, aber noch zu wenig atlantisch-europäisch geprägt ist. Das scheint mit ein Grund dafür zu sein, warum diese Avantgarde-Ansätze trotz ihres hochwertigen Anregungs- und Innovations-Potentials im Hinblick auf ein ganzheitliches Wissenschafts-Paradigma für das 21. Jahrhundert noch unübersehbare Schwierigkeiten haben, den atlantisch-europäisch geprägten Hauptstrom des Geistes-, Kultur- und politisch-sozialen Lebens ihrer Gesellschaft zu erreichen. Es zeigt sich, dass der innere Ausgleich zwischen pazifischen und atlantischen Ideen-Einflüssen eine der zentralen Herausforderungen für diese Avantgarde-Strömungen, aber darüber hinaus im Spiegelverhältnis auch für das europäische Kultur- und Gesellschafts-Paradigma sowie für die Entwicklung der integralen Bewegungen auf Weltebene insgesamt ist.

Declining price difference from gas to coal provides for a new situation in the electricity market; Sinkende Preisdifferenz von Gas zu Kohle sorgt fuer neue Lage am Strommarkt

The price difference (spread) between power coal and natural gas has increased sharply since 1999. This gap reached its peak in 2013 with 171 Euro/t SKE. In many cases, higher CO{sub 2} prices were required to promote gas use in the electricity sector. However, it has now become clear that falling gas prices lead to a growing competitiveness of natural gas. Interventions in the EU-ETS or at the national level with the aim to promote gas use in the electricity sector do not make sense and would merely reduce the competitive pressure on the gas producers and lead them to become a monopoly rents. [German] Der Preisabstand (Spread) zwischen Kraftwerkskohle und Erdgas stieg seit 1999 stark an. Dieser Gap erreichte in 2013 mit 171 Euro/t SKE seinen Hoechststand. Vielfach wurden hoehere CO{sub 2}-Preise gefordert, um den Gaseinsatz im Stromsektor zu foerdern. Doch inzwischen zeigt sich, dass fallende Gaspreise zu einer wachsenden Wettbewerbsfaehigkeit von Erdgas fuehren. Interventionen in das EU-ETS oder auf nationaler Ebene mit dem Ziel, den Gaseinsatz im Stromsektor zu foerdern, machen daher keinen Sinn und wuerden lediglich den Wettbewerbsdruck auf die Gasproduzenten mindern sowie fuer diese zu einer Monopolrente fuehren.

„Dichtes Verstehen“ als Schritt zu einer begegnenden Bibliothekskultur

Full Text Available Mit seiner ethnografischen Methode der dichten Beschreibung schlug der amerikanische Sozial­wissenschaftler Clifford Geertz eine völlig neue Richtung in der Kulturanthropologie ein. Diese sogenannte „interpretative Wende“ stellt auch jenseits der Ethnografie eine grosse Bereicherung dar. Überall wo Men­schen unterschiedlicher sozio-kultureller Herkunft aufeinander treffen, eignet sich die dichte Beschreibung, um kulturelle Bedeutungssysteme besser verstehen und einordnen zu können. Dies hilft nicht nur im Be­reich der qualitativen Sozialforschung, sondern auch ganz konkret im alltäglichen Leben, im privaten, wie auch im beruflichen Umgang mit fremden Erfahrungshorizonten. Denn die dichte Beschreibung sprengt vorgefertigte, „dünne“, sozio-kulturelle Typologien und Etikettierungen. Sie möchte vielmehr kulturelle Symbole auf deren tiefe Bedeutung phänomenologisch beschreiben und hermeneutisch ergründen. Diese Fähigkeit kann gerade auch im Umgang mit Kundinnen und Kunden im Bibliotheksbereich eine grosse Be­reicherung darstellen und dazu beitragen, eine positive Bibliothekskultur zu begründen. With his ethnographic approach Clifford Geertz established a new way of thinking and doing re­search in cultural anthropology. This so called “ethnographic turn” continues to be of great significance for many disciplines, not only for ethnological studies. Wherever people of different socio-cultural back­grounds meet, Geertz's method of “Thick Description” helps to understand foreign cultures, or, what Geertz calls “complex systems of meaning-making”. This is important for scientific research settings, but also for day-to-day encounters in multi-cultural societies in a globalized world. “Thin” forms of describing other­ness categorize, stereotype or come up with set explanations which will never be able to grasp the complex­ity and ever changing nature of peoples and cultures.

Dabei stellen sich die folgenden Fragen: Was können wir mit wenigen, aber aufwendigen Fallrekonstruktionen mit dem Ziel einer "theoretischen Verallgemeinerung" am Einzelfall im Unterschied zu qualitativen Verfahren mit umfangreichen Stichproben leisten, die eher eine numerische oder quantitative Verallgemeinerung zum Ziel haben? Inwiefern kommen wir damit überhaupt zu "allgemeinen" Aussagen über die soziale (kollektive und individuelle Wirklichkeit, über eine bestimmte Gruppierung, Organisation oder Ortsgemeinde, einen kollektiver Konflikt, ein bestimmtes Milieu oder soziales Netzwerk? Bei der Behandlung dieser Fragen geht es mir vor allem um ein Plädoyer für eine methodisch stärker historisch und prozess-soziologisch orientierte interpretative Sozialforschung.

Dieses Kapitel präsentiert Ergebnisse einer umfassenden Literaturauswertung zu relevanten Klimawirkungen für Deutschland, die im Rahmen des Projekts "Netzwerk Vulnerabilität" vorgenommen wurde. Es zeigt auf, dass ein aggregiertes Gesamtbild der Klimawirkungen für Deutschland als Grundlage für Folgenabschätzungen und Anpassungsplanungen noch nicht gezeichnet werden kann, da eine große Bandbreite an Ansätzen zur Bewertung von Vulnerabilitäten oder Klimawandelfolgen existiert und die gegenwärtig vorhandenen Klimawirkungs- und Vulnerabilitätsstudien von großer Heterogenität gekennzeichnet sind.

Sie ruht auf drei Säulen: kulturelle Breitenbildung für wenig bibliotheksaffine Kreise, allgemeine und breit gefächerte Öffentlichkeitsarbeit sowie Aktionen, die sich an spezielle communities in der Wissenschaft richten. Der Beitrag informiert auch über die erfolgreiche Umsetzung dieser Strategie anhand zahlreicher Beispiele. Er zeigt, wie es der Staatsbibliothek in der Hauptstadt Berlin, in der viele Gedächtnisinstitutionen tätig sind, gelingt, öffentlich präsent zu bleiben und ihr Profil zu vermitteln. The public relations work of the Berlin State Library – Prussian Cultural Heritage aims at effectively presenting its globally significant treasures as well as its services for the scientific world. It is based on three pillars: cultural education for the general public, especially for people who are not naturally close to libraries; a general and wide variety of public relations work; and events which target special communities in science. The paper also presents many examples for the effectual implementation of this strategy. It shows how the State Library, in the capital city of Berlin with its many memory institutions, succeeds in keeping a strong presence and communicating its profile to the public.

Sie holt jeweils verschieden weit aus, wenn es darum geht, künstlerische Herkunft, Biographie, Vorbilder und Ziele der Künstlerinnen zu deren Werk in Bezug zu setzten. Ohne zu bahnbrechend neuen Erkenntnissen zu kommen, gelingt es ihr doch, ein komplexes Bild der von ihr behandelten Filmemacherinnen und den Filmen zu entwerfen, das einen umfassenden Gesamteindruck vermittelt. Die Kürze des Buches bringt dabei eine Konzentration mit sich, die zu einer Weiterbeschäftigung und Vertiefung einlädt.What happens if the filmmaker directing the audience’s gaze is a woman? Radkiewicz uses two very different examples of “female” film art to portray the two directions into which this kind of undertaking can lead. In so doing, she demonstrates that traditional methods of analysis no longer suffice to thoroughly examine the work of an artist. Since there is no neatly defined category of “feminist art,” one has to take into consideration different kinds of approaches in order to do justice to the work of film directors like Jane Campion and Sally Potter. Radkiewicz does exactly that in her work, and thus provides an analysis that is informed by a feminist perspective. She includes the filmmakers’ artistic trajectory, background, biography, and goals into her interpretation of Campion’s and Potter’s films. While Radkiewicz does

Im internationalen Vergleich hat sich die wissenschaftliche Diskussion um die gesellschaftliche Relevanz des Phänomens „Social Entrepreneurship“ (SE) in Deutschland relativ spät entwickelt. In Asien wurde die Debatte insbesondere durch die von Muhammad Yunus 1983 gegründete Grameen Bank angestoßen und spätestens seit der Auszeichnung Yunus‘ mit dem Friedensnobelpreis wird SE in vielen Nationen zunehmend als Chance wahrgenommen, soziale Missstände effektiv und nachhaltig zu bekämpfen....

Full Text Available In seinem Theresienstadt 1941-1945 beschreibt Hans Günther Adler Episoden aus dem Prozess des Filmens in Theresienstadt. Seine größte Aufmerksamkeit liegt dabei auf der Produktion des Films von 1944, den er zusammenfassend aufgrund seines Zwecks und seiner Durchführung „der grausige Filmkarneval” nennt. Bemerkenswerterweise widmet Adler ein ganzes Buchkapitel der Beschreibung des kulturellen Lebens von Theresienstadt, ohne dabei den Film in zusammen mit anderen Beispielen kultureller Ausdrucksformen zu nennen – die Beschreibung des Films ist in der administrativen Chronik von Theresienstadt eingegliedert. Der Film erhält einen Platz für sich innerhalb des Kontextes der bürokratischen Umgestaltung Theresienstadts von einem geschlossenen Lager zu einem „Ghetto“ und schließlich zu einer rein dekorativen „jüdischen Siedlung“ hin. Diese letztere Umgestaltung beschreibt Adler als Teil einer zynischen Kampagne zur „Verschönerung“ von Theresienstadt, im Zuge derer SS und Verwaltung versuchten, das Lager für internationale Beobachter vorzeigbar zu machen. Adler beschreibt den „grausigen Filmkarneval“ als Aushängeschild der Kampagne und schließt ihn so entschieden aus dem Bereich kultureller Phänomene aus, als würde er jede Möglichkeit zu seiner Entlastung ablehnen. Stattdessen schreibt er das Projekt in die administrative Logik der Vernichtung ein, wodurch das Filmen zu einer zusätzlichen – in ihrer Grausamkeit ideenreichen und effektiven – Technik moralischer Vernichtung in der Welt des „verwalteten Menschen” avanciert. In diesem Artikel werde ich Adlers Sicht auf das Bewegtbild als überwiegend administratives Mittel, nicht als Medium kulturellen Ausdrucks hervorheben. Diese Ansicht wird durchaus herausfordernd und komplex, wenn Adlers Zeugenbericht über das Filmprojekt in Theresienstadt in Zusammenhang mit seinen Überlegungen zu mechanisch reproduzierbaren und vor allem bewegten Bildern in Adlers

Full Text Available Die mit dem Erscheinen von Judith Butlers Unbehagen der Geschlechter ausgelöste „Essentialismus versus Konstruktivismus“-Debatte um die Frage, wie Materialität und Körper zu denken sei, hält die Geschlechterforschung bis heute in dilemmatischer Spannung. Kann auf die Kategorie Geschlecht überhaupt verzichtet werden? Der Sammelband Verhandlungen des Geschlechts dokumentiert anhand von 15 Beiträgen aus den Bereichen Kulturwissenschaften, Philosophie, Psychoanalyse und Politik die aktuelle Entwicklung der Debatte rund um den an Butler orientierten feministischen Konstruktionsbegriff. Unter Rückgriff auf unterschiedliche Ansätze wird versucht, zwischen „Körper“ und „Diskurs“ zu vermitteln und Materialität neu zu denken.The “essentialism-versus-constructivism” debate which was sparked by Butler’s work, Gender Trouble, a debate centered around the question how to best think about materiality and bodies, continues to be relevant to gender studies to the present day. Is it at all possible to avoid gender as a category? 15 essays from scholars in cultural studies, philosophy, psycho-analysis, and politics document the current development of the debates that were inspired by Butler’s ideas about feminist constructions. Using a variety of different approaches, the authors attempt to mediate between the concepts of “body” and “discourse” and to conceive of materiality in a new way.

For years, debate has been raging on the future competitiveness of Germany. The discussions focus on wages and incidental wage costs, working hours, the education and training system, technological changes, flexibilization and the fight against red tape as well as social consensus. But one site-related factor hardly crops up in public discussion and in economic-science textbook and expertises, although it quite essentially influences competitiveness, now even more than formerly: the mentality of the population. It includes priorities held by society, target concepts such as the openness of the population towards innovation and its attitude towards technology and technical progress as well as the way in which discussions are conducted in society and decisions taken, especially also people`s inclination to rationality or irrationality, and proneness to emotions or ideological thinking. (orig.) [Deutsch] Seit Jahren wird ueber die Zukunft des Standortes Deutschland diskutiert und gestritten. Im Mittelpunkt der Diskussion stehen Loehne und Lohnnebenkosten, Arbeitszeiten, das Bildungs- und Ausbildungssystem, technologische Veraenderungen, Flexibilisierung und Entbuerokratisierung und der soziale Frieden. Ein Standortfaktor kommt dagegen in der oeffentlichen Diskussion wie auch in den wirtschaftswissenschaftlichen Lehrbuechern und Expertisen kaum vor, obwohl er die Standortqualitaet ganz wesentlich beeinflusst, heute noch mehr als frueher: Die Mentalitaet der Bevoelkerung. Dazu gehoeren die gesellschaftlichen Prioritaeten und Zielvorstellungen wie die Innovationsoffenheit der Bevoelkerung, ihre Einstellung zu Technik und technischem Fortschritt wie die Art, gesellschaftliche Diskussionen zu fuehren und Entscheidungen zu treffen, besonders auch die Neigung zu Rationalitaet und Irrationalitaet, die Anfaelligkeit fuer Emotionen und Ideologisierung.

The Working Group on Procedures for the Selection of Repository Sites (AkEnd) had been appointed by the German Federal Ministry for the Environment (BMU) to develop procedures and criteria for the search for, and selection of, a repository site for all kinds of radioactive waste in deep geologic formations in Germany. ILK in principle welcomes the attempt on the part of AkEnd to develop a systematic procedure. On the other hand, ILK considers the two constraints imposed by BMU inappropriate: AkEnd was not to take into account the two existing sites of Konrad and Gorleben and, instead, work from a so-called white map of Germany. ILK recommends to perform a comprehensive safety analysis of Gorleben and define a selection procedure including the facts about Gorleben and, in addition, to commission the Konrad repository as soon as possible. The one-repository concept established as a precondition by BMU greatly restricts the selection procedure. There are no technical or scientific reasons for such concept. ILK recommends to plan for separate repositories, which would also correspond to international practice. The geoscientific criteria proposed by AkEnd should be examined and revised. With respect to the site selection procedure proposed, ILK feels that procedure is unable to define a targeted approach. Great importance must be attributed to public participation. The final site selection must be made under the responsibility of the government or the parliament. (orig.)

Purpose: How much can the radiation dose be reduced for skull radiography by using digital luminescence radiography (DLR) compared to a conventional screen film system with a grid cassette? Methods and Materials: A skull phantom (3M) was X-rayed in anterior-posterior orientation using both a conventional screen film system with grid cassette and DLR (ADC-70, Agfa). The tube current time product (mAs) was diminished gradually while keeping the voltage constant. The surface entrance dose was measured by a sensor of Dosimax (Wellhoefer). Five investigators evaluated the images by characteristic and critical features, spatial resolution and contrast. Results: The surface entrance dose at 73 kV/22 mAs was 0,432 mGy in conventional screen film system and 0,435 mGy in DLR. The images could be evaluated very well down to an average dose of 71% (0,308 mGy; SD 0,050); sufficient images were obtained down to an average dose of 31% (0,136 mGy; SD 0,065). The resolution of the line pairs were reduced down to a 2 levels depending on the investigator. Contrast was assessed as being very good to sufficient. The acceptance of the postprocessed images (MUSICA-software) was individually different and resultde in an improvement of the assessment of bone structures an contrast in higher dose ranges only. Conclusion: For the sufficient assessment of a possible fracture/of paranasal sinuses/of measurement the skull the dose can be reduced to at least 56% (31%; SD 14,9%)/40% (27%; SD 9,3%)/18% (14%; SD 4,4%). Digital radiography allows question-referred exposure parameters with clearly reduced dose, so e.g. for fracture exclusion 73 kV/12,5 mAs and to skull measurement 73 kV/4 mAs. (orig.)

Von Neuromancer zu Second Life. Raumsimulationen im Cyberspace

Directory of Open Access Journals (Sweden)

Krämer, Steffen

2011-07-01

Full Text Available In his novel Neuromancer, first published in 1984, the US-american author William Gibson coined the term cyberspace for the virtual reality generated by computers. On the basis of an etymological analysis this term can be interpreted as the traditional relation between helmsman and space. In the medium of sci-fi-literature and sci-fi-film this phenomenon of cyberspace changed rapidly between 1980 and today. In early examples, for instance in the film Tron produced in 1982, the virtual figures act in a disintegrated space without any destination or orientation. In later examples, for instance in the film Matrix produced in 1999, the cyberspace becomes a substitute world for a dark, chaotic or destructive vision of reality. Contemporary forms of cyberspace, as visualized in the 3D-online-city Second Life, are in contrast used for financial activities and symbolize the hard world of economic policy. This development of cyberspace can be seen either as an evolutionary process or a dichotomy primary defined by different facets of space simulation in virtual reality.

Test methods for laser welds were investigated under the following aspects: 1. Setting a defined cracking path by changing the test piece geometry - is it possible and does it make sense? 2. Can the results obtained with changed test piece geometries be applied to standard test pieces? 3. Is crack displacement typical of small test pieces, or is it observable in real components as well? 4. Should the cracking path be predefined at all if it results in 'non-realistic' fractures? The focus was on notched bar impact tests. [German] Ziel des Forschungsvorhabens war die Ermittlung geeigneter Pruefverfahren zur Charakterisierung einer Laserstrahlschweissnaht. Folgende Fragen sollten geklaert werden: 1. Ist es moeglich und sinnvoll, mit einer Aenderung der Probengeometrie (z.B. Einbringen von Seitenkerben) den Rissverlauf in das aufgehaertete Laserschweissgut zu zwingen? 2. Welche Aussagen liefern uns die Ergebnisse dieser abgeaenderten Probengeometrie und inwiefern sind diese vor allen Dingen beim Kerbschlagbiegeversuch auf die Ergebnisse der standardisierten Probengeometrie zu uebertragen? 3.

Full Text Available Die Debatte um die Differenz von „Verantwortung“ und „Pflicht“ ist kein bloßer Streit um Wörter, geht es doch um Begriffe, für die der Anspruch erhoben wird, sie seien konstitutiv für moralische Normativität oder gar für Normativität per se. Doch welchen Unterschied macht es, die besondere Bindungskraft von Normativität über Verantwortung oder über Pflicht zu explizieren? Die Genealogie der philosophischen Reflexionen auf Verantwortung lokalisiert die Differenz zwischen Pflicht und Verantwortung in den jeweiligen Selbstverhältnissen, die mit diesen Begriffen verbunden werden. Die Analyse der Struktur dieser Selbstverhältnisse erklärt sowohl, warum Verantwortung häufig als moderner Ersatzbegriff für Pflicht gedacht wird, als auch, welchen Unterschied die Explikation der Bindungskraft von Normativität über Verantwortung oder Pflicht macht: Je nachdem, mit welchem Begriff normative Kraft erläutert wird, wandert das entsprechende Selbstverhältnis in die Verfasstheit von Normativität ein.

In den sauren Apfel beißen. Naturkundliche Lehrmittelensembles in historischer Perspektive

Michael Markert

Full Text Available Naturkundlicher Unterricht praktiziert eine materielle Kultur der Anschauung, die eingesetzten und überlieferten Lehr-Dinge sind deren kulturelle Artefakte. Über eine damit verbundene Unterrichtspraxis zu sprechen bedeutet, diese Dinge als materielle Träger von Bedeutung in spezifischen Gebrauchskontexten zu begreifen und deshalb zugleich die mit ihnen verbundenen Handlungen und Routinen, etwa in der Zerlegung eines Modells oder der Inszenierung eines Schulwandbildes im Klassenraum, zu untersuchen. Damit ist historische Lehrmittelforschung zugleich auch eine Medienarchäologie in dem Sinne, dass nicht nur die erhaltenen Artefakte inhaltsanalytisch ausgewertet werden, sondern auch versucht wird, die historischen Praktiken des Gebrauchs und der Überlieferung zu berücksichtigen. Dieser Beitrag wird anhand des Gegenstandsbereichs 'Apfel' die historische Bandbreite verschiedener Lehrmittel (Lehrbuch, Lehrmodel, Naturobjekt, Wandtafel, Film, Dia, Folie, DVD-Medienpaket vor Augen führen und mit Hinweisen zu Mediengeschichte und Mediengebrauch auf die unterrichtliche Praxis referenzieren, um einen Einblick in die materielle Kultur der Lehre zu geben. Natural history education practices a material culture of perception. The utilized teaching objects are the artefacts of this culture. To speak about the interlinked teaching practices means to understand the objects as material carriers of meaning in special contexts of usage and to analyze the related actions and routines – for example the decomposition of a teaching model or the staging of a wall chart. Thus the historical research on teaching materials is a media archology in the sense that the surviving artefacts are analyzed in their historical teaching practices. This paper examines the historical spectrum of different teaching materials like textbook, model, wallchart, film and slide focusing on the ordinary 'apple' as a wide-spread subject matter of education.

Full Text Available Die vorliegende Arbeit behandelt den Ortsnamen Šepšin, wie ein Dorf in Serbien unweit von Mladenovac, südlich von Belgrad, heißt. Nach dem Zeugnis der türkischen Verzeichnisse des 16. Jh.s, hat sich die heutige Form des Namens über Šemšin aus Šemčin entwickelt, wie sein Erstbeleg aus 1528 lautet. Vorausgesetzt, dass sich das anlautende Š- aus S- durch Assimilation vom Typ šiče < siče ‘zischt’ entwickelt hat, lässt sich die ursprügliche Namenform als *Sěmčijin wiederherstellen, wo sich um ein Possessivadjektiv zur altserbischen Amtsbezeichnung sěmьčija handelt. Nur als Hapax in der BanjskaUrkunde aus 1316. belegt, wird sie mit aksl. samъčii ‘praefectus’ gleichgesetzt, wo wahrscheinlich ein Lehnwort aus dem Protobulgarischen vorliegt. In diesem Fall liesse sich das ě der altserbischen Nebenform durch den Einfluss des urslav. Wortes *sěmь ‘Familie’ erklären. Anknüpfend wird die Frage nach der Herkunft eines anderen Ortsnamens aus demselben Gebiet, Hrčin, heute Vrčin, wieder in Betracht gezogen. Bisher unterschiedlich gedeutet, lässt sich er analogisch zu *Sěmčijin auf *Hrtčijin als Possessivbildung zur sonst unbelegten Hofamtsbezeichnung *xъrtьčii ‘für Windhunde (*xъrtъ zuständig, Hofjägermeister’ zurückführen. In beiden Fällen dürfte sich das maskuline Possessivadjektiv auf -in ursprünglich auf potok ‘Bach’ oder dol ‘Tal’ im Lehensbesitz der betreffenden Person bezogen haben.

Coprocessing of petroleum residues and plastics is a promising technology, although some problems concerning waste plastics must be clarified prior to its implementation. In general, it can be stated that with a careful choice of operating parameter combinations, oil yields will be higher than for thermal treatment of petroleum residues alone (e.g. a 35% yield increase is achieved by adding 25% of plastics, which is a disproportionately high increase). Waste plastics thus become a valuable material for processing. (orig.) [Deutsch] Das untersuchte Coprocessing von VR und Kunststoffen ist ein erfolgversprechender Weg der Kunststoffverwertung und des tiefen Crackens von Erdoelrueckstand. Die Klaerung der mit Altkunststoffen verbundenen Fragen bedarf weiterer Untersuchungen. Allgemein kann festgestellt werden, dass bei entsprechenden Parameterkombinationen bessere Oelausbeuten erzielt werden als bei der thermischen Behandlung von reinem VR. Ein Beispiel dafuer ist in der Abbildung 10 dargestellt. Durch eine 25%-ige Erhoehung der Einsatzstoffmasse durch Kunststoffzugabe wird eine im Vergleich zu reinem VR um ca. 36% hoehere Oelausbeute erzielt, was einer ueberproportionalen Erhoehung entspricht. Altkunststoff wird bei diesem Prozess unter Nutzung des Wasserstoff-potentials von Polymeren zu einem wertvollen Einsatzstoff. (orig.)

Mehr Last als Lust – Ein weiterer Sammelband zu „(Frauen-Körper“ More Encumbrance than Enjoyment

Directory of Open Access Journals (Sweden)

Paula-Irene Villa

2006-11-01

Full Text Available Dieser Band vereint acht heterogene Aufsätze zu „Lust und Last am eigenen Körper“ von Frauen. Alle Beiträge gehören zum Spektrum psychologischer Reflexion; die Themen reichen dabei von Sport über Kochen und Essen bis Schönheit, die Zugänge von Psychoanalyse über experimentelle Psychologie bis hin zu freier Assoziation auf der Grundlage klinisch-praktischer Arbeit. Ein roter Faden durch die Beiträge ist nicht erkennbar und so wirkt die Vielfalt beliebig. So unterschiedlich die Beiträge sind, so unterschiedlich ist auch ihre Qualität. Leider kommen einige Artikel über die unkritische Zusammenstellung anderer Arbeiten nicht hinaus, die meisten nehmen kaum Bezug auf das inzwischen breite und institutionalisierte Feld der (sozial- und kulturwissenschaftlichen Körperforschung. Doch haben manche Aufsätze interessante empirische Einblicke zu bieten, die zur weiteren Reflexion anregen, und einige wenige Beiträge sind so differenziert, dass sich mit ihnen weiterdenken und -forschen lässt. Insgesamt bereitet die Lektüre des Buches weder ‚Einsteiger/-innen‘ noch ‚Fortgeschrittenen‘ der wissenschaftlichen Beschäftigung mit (Frauen-Körpern Lust, sondern erweist sich – bis auf Ausnahmen, die allerdings auch in ausführlicherer Form anderenorts publiziert wurden – eher als Last. Ärgerlich und alles andere als argumentativ überzeugend ist darüber hinaus das in manchen Texten enthaltene, mehr oder minder explizit artikulierte, ‚Feminismus- bzw.

Full Text Available Die hier besprochene Monographie der Linguistin Anja Gottburgsen beschäftigt sich theoretisch und empirisch mit sprachbezogenen Geschlechterstereotypen, also mit unseren Vorstellungen darüber, ob und wie Männer und Frauen jeweils in spezifischer und distinkter Weise sprachlich kommunizieren. Im Theorieteil der Arbeit wird der aktuelle Stand der soziolinguistischen und sozialpsychologischen Diskussion zu Geschlecht, Sprachverhalten und Stereotypisierung kritisch referiert und die Bedeutung von sprachbezogenen Geschlechterstereotypen erläutert. Im empirischen Teil berichtet die Autorin die Ergebnisse von drei Fragebogen-Studien mit deutschsprachigen Studierenden. Es zeigt sich, dass bei Studierenden unabhängig von Geschlecht und Geschlechtsrollenorientierung stereotype Vorstellungen über das sprachliche Verhalten von Männern und Frauen verbreitet sind.

Allowing more competition in all sectors of the economy is an acceptable strategy if resulting in social benefits, i.e. if profits are passed on to the citizens and consumers. If, however, such a liberalisation or deregulation ends up in a concentration of power by commercial enterprises to the disadvantage of consumers who have to pay higher electricity rates, or jeopardizes the reliability of power supply, such actionism on the part of the legislature may well adversely affect public welfare. This applies likewise to minor regulation, as is the Act on Compulsory Acceptance of Electricity From Renewable Energy Sources,(SEG), which puts an unproportionate load on the shoulders of the public utilities in order to satisfy interests of environmental policy. The paper explains these statements by examining effects expected to result from the SEG, and by referring to problems involved in the phaseout of franchise agreements. (orig./HSCH) [Deutsch] Die Einfuehrung von mehr Wettbewerb in allen Bereichen der Wirtschaft ist zu begruessen, wenn sich volkswirtschaftlich positive Entwicklungen einstellen, d.h. der Buerger, der Kunde davon profitiert. Wenn liberalisierende Eingriffe letztlich aber zu hoeheren Strompreisen oder zu geringerer Versorgungssicherheit fuehren, bei gleichzeitigem Konzentrationsschub in der Unternehmensstruktur, dann kann das Gemeinwohl durch gesetzgeberischen Aktionismus leicht Schaden nehmen. Dies gilt auch fuer Regulierungen minderer Art wie beim Stromeinspeisungsgesetzt (SEG), das die deutschen Energieversorgungsunternehmen (EVU) aus umweltpolitischen Erwaegungen weiter einseitig belastet.

The cleaning of flue gases imposes extreme demands on the material concerned. By keeping below the acid dewpoint, this leads to condensation of acid products on the heating surfaces. The correct selection of the appropriate material is decisive for the availability of the overall plant. In the case of the application described in this paper, it has been possible to show that nickel-based alloys are outstandingly suitable for withstanding those kinds of stresses over many years. However, independently of this, it is valid to test material selection for each individual case of application. (orig.) [Deutsch] Die Reinigung von Rauchgasen stellt extreme Anforderungen an den jeweiligen Werkstoff. Durch die Unterschreitung des Saeuretaupunktes kommt es dabei zu einer Kondensation der Saeureprodukte auf den Heizflaechen. Die Auswahl des geeigneten Materials ist entscheidend fuer die Verfuegbarkeit der Gesamtanlage. In dem hier dargestellten Anwendungsfall konnte gezeigt werden, dass Nickelbasis-Legierungen hervorragend geeignet sind, einer derartigen Beanspruchung ueber Jahre hinaus standzuhalten. Unabhaengig hiervon gilt es jedoch, fuer die Materialauswahl jeden Anwendungsfall einzeln zu pruefen. (orig.)

Präferenzen, Wohlergehen und Rationalität – Zu den begrifflichen Grundlagen des libertären Paternalismus und ihren Konsequenzen für seine Legitimierbarkeit

2016-07-01

Full Text Available Der libertäre Paternalismus (LP genießt in Politik, Wissenschaft und Öffentlichkeit eine große Popularität, die er insbesondere zwei Merkmalen verdankt: Erstens stützt sich der LP auf verhaltensökonomische Ergebnisse, die zeigen, dass individuelle Entscheidungen oft nicht der neoklassischen Rationalitätskonzeption entsprechen, sodass Individuen durch sogenanntes Nudging zu besseren, ihren wahren Präferenzen entsprechenden Entscheidungen verholfen werden könne. Zweites ist damit der Anspruch verbunden, das Wohlergehen der Individuen, wie sie selbst es verstehen, zu erhöhen. Dieser Beitrag zeigt anhand einer dogmengeschichtlichen Analyse der zentralen, dem LP zugrunde liegenden Begriffe Präferenz, Nutzen, Rationalität und Wohlergehen, dass der LP diesen Anspruch nicht einlösen kann. Eine detaillierte begriffliche Analyse ist deshalb geboten, weil diese Konzepte in der Ökonomik immer wieder für Missverständnisse sorgen. Eine theoriegeschichtlich informierte Untersuchung wiederum ist notwendig, da diese Konfusion insbesondere auf der Tatsache beruht, dass der Gehalt dieser Begriffe sich im Laufe der Zeit gravierend verändert hat und sich die verschiedenen Bedeutungen heute z. T. wechselseitig überlagern.

Dieses Verfahren wurde seit einer Anpassung des Arbeitsplanes im Jahr 2000 im Vorhaben verfolgt und konnte die damaligen hohen Erwartungen sogar noch uebertreffen. Es wird in einem Anschlussvorhaben weiterentwickelt, um unter anderem belastbare Fakten zu Fragen der industriellen Anwendbarkeit zu sammeln. Die direkte Herstellung effizienter polykristalliner Siliciumsolarzellen auf Glassubstraten bei Temperaturen zwischen 400 und 600 C erwies sich als aeusserst schwierig und vermutlich unmoeglich. Zum ersten Mal konnte eine umfassende Analyse der grundsaetzlichen Begrenzungen fuer pn-Solarzellen aus Silicium mit Korngroessen im Bereich von (1-100) {mu}m vorgelegt werden. Der Durchgang von Korngrenzen durch den pn-Uebergang begrenzt in diesem Korngroessenbereich die erreichbare Ausgangsspannung prinzipiell auf inakzeptabel niedrige Werte. Die thermokatalytische Abscheidung (hot-wire CVD) nanokristalliner Si-Filme (nc-Si) fuer den Einsatz in gestapelten, mikromorphen Solarzellen konnte dahingehend optimiert werden, dass Schichten mit ausschliesslicher <110>-Textur erzielt wurden. Solche Schichten zeigen stabile elektronische Eigenschaften; Veraenderungen durch die Aufnahme von atmosphaerischem Sauerstoff, Wasser usw. koennen damit vermieden werden. Der Einsatz in Solarzellen scheint jedoch der geringen Abscheiderate wegen wenig sinnvoll. Hier zeigte sich, dass Schichten guter elektronischer Qualitaet in hot-wire CVD aehnlich niedrige Abscheideraten erfordern wie in plasmagestuetzten Verfahren. Weitere Ergebnisse in den Bereichen Ionenunterstuetzte Abscheidung (IAD), Laserkristallisation und Si-Hetero-Solarzellen koennen als spin-off fuer andere Anwendungen genutzt werden. (orig.)

Magnetic resonance imaging (MRI) is one of the most powerful and at the same time gentlest clinical imaging techniques at the present time; however, the enormous physical complexity as well as simple inattentiveness (projectile effect) implicate a significant risk potential and place high demands on the MR operator to ensure a safe workflow. A sound knowledge of the potential MR interactions is the foundation for a safe and profitable operation for all parties. The first part of this article deals with the three most important sources of physical interaction, i.e. static magnetic field, gradient and high-frequency (HF) fields. The paper discusses the differences between each type of field with respect to the impact on human beings, the interactions with magnetic and electrically conducting objects/implants and the relevant safety standards. Each section is followed by simple rules of thumb to minimize potentially unwanted physical MRI interactions. (orig.)

Full Text Available Das Prostatakarzinom stellt heute in der westlichen Welt das am häufigsten diagnostizierte Karzinom beim Mann dar. Entsprechend dieser Häufigkeit werden zunehmend radikale Prostatektomien durchgeführt. Die histologische Aufarbeitung des Operationspräparates liefert dem Urologen die wichtigsten Prognosefaktoren des Prostatakarzinoms. Hierbei besteht ein enger Zusammenhang zwischen der extraprostatischen Ausdehnung des Tumors und seiner Beziehung zu den Resektionsrändern. Anhand einer eigenen Untersuchung an 200 radikal operierten Prostatakarzinomen konnte gezeigt werden, dass hierbei die Lokalisation, der Malignitätsgrad und die Größe des Tumors entscheidende Bedeutung haben. Die Ermittlung dieser Parameter ist abhängig von einer standardisierten Untersuchungstechnik auf der Grundlage einer vollständigen histologischen Aufarbeitung der Prostata.

Only 6 days after the increase in pH with water saturation the concentration of iron in the pore water of the T1 sediment had dropped to a low value, 70% of which was accounted for by Fe(II). This is probably due to the almost complete precipitation of Fe(III) caused by the high pH values. Compared with the untreated variant the lowering of pH in the further course of the experiment led to a slight Fe(III) mobilisation and hence, through interaction with other reduction processes, to erratic changes in the share of Fe(II) in total Fe. Although this sediment showed a relatively low iron concentration a comparison showed that higher pH values and incubation temperatures have an influence on microbial iron reduction. [German] Im Porenwasser des Sedimentes T1 lag Eisen bereits 6 Tage nach pH-Erhoehung und Wassersaettigung nur noch in geringer Konzentration und zu ueber 70% als Fe(II) vor. Dies ist vermutlich in erster Linie auf die nahezu vollstaendige Ausfaellung von Fe(III) infolge der hohen pH-Werte zurueckzufuehren. Im weiteren Versuchsverlauf fuehrte das Absinken der pH-Werte zu einer im Vergleich zur unbehandelten Variante geringfuegigen Fe(III)-Mobilisierung und damit in Wechselwirkung mit ablaufenden Reduktionsprozessen zu unstetigen Veraenderungen in den Anteilen Fe(II) an Fe{sub ges}. Obwohl in diesem Sediment nur vergleichsweise niedrige Eisenkonzentrationen vorliegen, ergab ein Vergleich, dass hoehere pH-Werte und Inkubationtemperaturen die mikrobielle Eisenreduktion beeinflussen.

Full Text Available Im neueren Denken Judith Butlers nimmt der Begriff der Vulnerabilität eine Schlüsselrolle ein. Kaum eines der vielen Themen, denen sich die US-amerikanische Autorin seit der Jahrtausendwende widmet, kann ohne Kenntnis ihrer Überlegungen zu diesem Terminus angemessen verstanden werden. Der Versuch einer Rekonstruktion ihrer Konzeption von Vulnerabilität steht allerdings vor der Schwierigkeit, dass Butlers Gedanken hierzu über zahlreiche Texte hinweg verstreut sind, wobei bisweilen unterschiedliche Aspekte betont und verschiedene Schwerpunktsetzungen vorgenommen werden. Im vorliegenden Beitrag werden Butlers vulnerabilitätstheoretische Ausführungen in gebündelter Weise dargestellt und interpretiert. Dabei wird (1 die Bedeutsamkeit von Butlers Überlegungen zur Vulnerabilität für ihre Vorstellung von Körperlichkeit aufgewiesen, (2 der Zusammenhang von Vulnerabilität und Anerkennung erläutert und (3 gezeigt, welche ethischen Erwägungen Butler ausgehend von ihrer Anerkennungskonzeption und ihrem Denken der Vulnerabilität anstellt und inwiefern Vulnerabilität und politische Handlungsfähigkeit einander nicht ausschließen. Abschließend wird (4 Butlers Vulnerabilitätsverständnis mit einigen kritischen Rückfragen konfrontiert.

Film quality in film mammography. Pt. 2

International Nuclear Information System (INIS)

Friedrich, M.; Weskamp, P.; Freie Univ. Berlin

1976-01-01

During consideration of three film mammographic systems, the concept of signal/noise ratio is developed as a quantitative measure of film quality. The ability to recognise detail related to detail size, film blackening and exposure geometry was studied for various systems, and the quality profiles are discussed. There is a considerable difference in quality between industrial films without screens and film-screen combinations; however, exposure geometry during mammography has a considerable effect which tends to reduce the difference. Consequently, detail sizes of 200 μ to 1,000 μ (including the majority of mammographic micro-calcifications) are shown about equally well. Contrast for the lo-dose system is somewhat less than for adequately exposed industrial film. Over-exposure with the lo-dose system, contrary to industrial film, rapidly leads to unsatisfactory results. On the other hand it is often not possible to obtain an adequate exposure when using industrial film. For these reasons it is often an advantage to examine large breasts and the dense breasts of young women with a film-screen combination which requires approximately one eighth of the dose necessary for industrial film. For small or easily compressable breasts best results are obtained, using an adequate exposure by employing industril film; radiation dose it then acceptable. (orig./ORU) [de

The hazard potential of contaminated sites is evaluated by means of risk assessments. These can entail diverse measures being taken that may range from the mere observation of the site over protective and restricting measures, different encapsulations to ensure its safety as well as the shifting of contaminated matter, to the decontamination of the site (Council of Experts on Environmental Questions SRU, 1990). Of these measures, soil cleaning demands the greatest effort and should lastingly repair the damage without new damage being caused in another place. (orig.)

Influence of film dimensions on film droplet formation.

Science.gov (United States)

Holmgren, Helene; Ljungström, Evert

2012-02-01

Aerosol particles may be generated from rupturing liquid films through a droplet formation mechanism. The present work was undertaken with the aim to throw some light on the influence of film dimensions on droplet formation with possible consequences for exhaled breath aerosol formation. The film droplet formation process was mimicked by using a purpose-built device, where fluid films were spanned across holes of known diameters. As the films burst, droplets were formed and the number and size distributions of the resulting droplets were determined. No general relation could be found between hole diameter and the number of droplets generated per unit surface area of fluid film. Averaged over all film sizes, a higher surface tension yielded higher concentrations of droplets. Surface tension did not influence the resulting droplet diameter, but it was found that smaller films generated smaller droplets. This study shows that small fluid films generate droplets as efficiently as large films, and that droplets may well be generated from films with diameters below 1 mm. This has implications for the formation of film droplets from reopening of closed airways because human terminal bronchioles are of similar dimensions. Thus, the results provide support for the earlier proposed mechanism where reopening of closed airways is one origin of exhaled particles.

Full Text Available Sheila Jeffreys analysiert die Prozesse, die zu einer Industrialisierung und Globalisierung von Prostitution im späten 20. und 21. Jahrhundert geführt haben. Hauptverantwortlich für die gegenwärtige Diskursverschiebung um Prostitution ist für Jeffreys zum einen die sexuelle Revolution der 1970er Jahre und zum anderen die massive Finanzierung von Unterstützer/-innen der Sexarbeiterinnen zur HIV-Prävention in den 1980ern. Jeffreys legt wie in früheren Arbeiten ihre radikal-feministische Position dar und fordert eine Abschaffung der Prostitution. In ihrer Abrechnung mit dem liberalen feministischen Diskurs, für den eine Unterstützung von Sexarbeiterinnen prioritär ist, ignoriert sie die Widersprüchlichkeiten und Komplexitäten der gelebten Realitäten. An vielen Stellen ihres Buches bekräftigt Jeffreys stereotypische Männlichkeitsvorstellungen, was durch einen Blick über den Tellerrand des ihr vertrauten wissenschaftlichen Bezugsrahmens hätte vermieden werden können.

Gerechtigkeit, ethische Subjektivität und Alterität. Zu den normativen Implikationen der Philosophie von Emmanuel Levinas

Seitz Sergej

2016-07-01

Full Text Available Obwohl seit einiger Zeit ein verstärktes Forschungsinteresse an Emmanuel Levinas’ Denken des Politischen, verbunden mit einer genaueren Inblicknahme der zentralen Begriffe des Dritten und der Gerechtigkeit aufgekommen ist, blieb bislang unklar, inwiefern aus Levinas’ intrinsisch ‚ethischem‘ Denken in konkreterer Weise normative Konsequenzen zu ziehen sind. Diesem Desiderat versucht der vorliegende Beitrag nachzukommen. Das Levinas’sche Gerechtigkeitsdenken wird dabei so eingeführt, dass es zugleich als alternativer Entwurf und als produktive kritische Provokation für gegenwärtige Gerechtigkeitstheorien lesbar wird. Ausgehend von einer Rekonstruktion des alteritären Verständnisses ethischer Subjektivität, wie es Levinas insbesondere in Jenseits des Seins erarbeitet, wird ausgelotet, wie tragfähig Levinas’ ethische Konzeption plural alteritär durchfurchter Subjektivität für normative Gerechtigkeitsfragen ist. Aus einer Reflexion auf den Begriff des ‚Dritten‘ werden einige konkrete Konsequenzen für das Denken gerechter Institutionen gezogen.

Equilibrium helium film in the thick film limit

International Nuclear Information System (INIS)

Klier, J.; Schletterer, F.; Leiderer, P.; Shikin, V.

2003-01-01

For the thickness of a liquid or solid quantum film, like liquid helium or solid hydrogen, there exist still open questions about how the film thickness develops in certain limits. One of these is the thick film limit, i.e., the crossover from the thick film to bulk. We have performed measurements in this range using the surface plasmon resonance technique and an evaporated Ag film deposited on glass as substrate. The thickness of the adsorbed helium film is varied by changing the distance h of the bulk reservoir to the surface of the substrate. In the limiting case, when h > 0, the film thickness approaches about 100 nm following the van der Waals law in the retarded regime. The film thickness and its dependence on h is precisely determined and theoretically modeled. The equilibrium film thickness behaviour is discussed in detail. The agreement between theory and experiment is very good

New recognitions in the sectors of research, development in the processing industry, motor vehicle technology, ecological balance methodics, the high interest in environmental policy and some other points of criticism have motivated the Umweltbundesamt to update the corresponding parts of the '1993 eco-balance rape oil'. Balancing of the particularly critically discussed sectors of resource consumption and airborne environmental impacts over the entire life cycle of rape oil based fuels as compared to diesel fuel was taken care of by the ifeu Institute. That balances were only made up for these two sectors is due to the fact that it is here where the particular environmental advantages of vegetable fuel oils are supposedly brought to bear. Moreover, on the basis of the report 'renewable energy sources - fundamentals, methods, ecological balancing' published recently and sponsored by the Deutsche Bundesstiftung Umwelt, topical essential factors such as the redefinition of the reference system (short-rotation cultivation instead of permanent fallowness) could be taken into account by the expertise. A particular benefit attributed to rape oil and RME is the conservation of fossil energy sources and associated abatement of the greenhouse effect (especially carbon dioxide). Cutting down greenhouse gas emissions is one of the predominant aims of national and international environmental policy with a view to preventing a dangerous man-made disturbance of climate. (orig.)

Full Text Available Die These dieses Aufsatzes lautet, dass im medienpädagogischen Handeln und Kommunizieren Erfahrungen mit dinglich gegebenen Medien verarbeitet und dass dadurch Medienensembles konstruiert werden, also praktisch verfügbare Konfigurationen von Geräten und Gegenständen, unter denen die beteiligten Akteure eine Auswahl treffen können. Der Begriff der Wahl lässt insbesondere einen Anschluss an die Idee einer demokratischen Medienbildung zu. Als erkenntnistheoretische Grundlage wird eine Orientierung an der sinnlichen Erfahrung vorgeschlagen, die gerade in Immanuel Kants "Kritik der reinen Vernunft" als Erkenntnisquelle begründet wird. Dass der Begriff der Medienensembles auch die historische Dimension aufschließen kann, wird am Beispiel des so genannten Neumagener Schulreliefs gezeigt, einem archäologischen Dokument aus der Zeit um 180 n.Chr. This essay proposes the thesis that media education should be understood as consisting in negotiations about experiences with media ensembles. In a constructivist approach, the acting with media ensembles is seen as a form of coming to terms with devices and other media objects that are accessible via sensory experience. In this context, a pivotal idea is that choices are made between different media that are at hand for educational purposes. This concept is further elaborated in the concepts of Immanuel Kant's theory of perception. As an example, an archaeological monument from ca. 180 AD ("Neumagener Schulrelief" is described and interpreted.

The focused ion beam (FIB) microscope has become an important tool for the preparation of TEM samples over the last few years. Preparation of samples with the FIB has some specific advantages over conventional preparation methods which make it possible to prepare samples that would otherwise be difficult to prepare. The advantages that will be illustrated in this paper include: (1) precise selection of the sample volume to be prepared, (2) preparation of brittle materials, (3) preparation of highly stressed materials, and (4) preparation of composites composed of materials with widely differing properties. These advantages will be illustrated through several examples including cross-sectional preparation of nanocrystalline Ti-Si-N films, thermal barrier coatings, fatigued Al films, pecan shells, apatite, and metal whiskers. [German] Das Focused Ion Beam (FIB)-Mikroskop ist in den letzten Jahren zu einem wichtigen Werkzeug fuer die Praeparation von TEM-Proben geworden.

Single-layer nano-carbon film, diamond film, and diamond/nano-carbon composite film field emission performance comparison

Wang, Xiaoping; Wang, Jinye; Wang, Lijun

2016-01-01

A series of single-layer nano-carbon (SNC) films, diamond films, and diamond/nano-carbon (D/NC) composite films have been prepared on the highly doped silicon substrate by using microwave plasma chemical vapor deposition techniques. The films were characterised by scanning electron microscopy, Raman spectroscopy, and field emission I-V measurements. The experimental results indicated that the field emission maximum current density of D/NC composite films is 11.8–17.8 times that of diamond films. And the field emission current density of D/NC composite films is 2.9–5 times that of SNC films at an electric field of 3.0 V/μm. At the same time, the D/NC composite film exhibits the advantage of improved reproducibility and long term stability (both of the nano-carbon film within the D/NC composite cathode and the SNC cathode were prepared under the same experimental conditions). And for the D/NC composite sample, a high current density of 10 mA/cm"2 at an electric field of 3.0 V/μm was obtained. Diamond layer can effectively improve the field emission characteristics of nano-carbon film. The reason may be due to the diamond film acts as the electron acceleration layer.

Results available so far of calculations based on the cost-benefit analysis show that the targets involved, such as cutback of emissions and conservation of resources, can be realised within the foreseeable future at much lesser expense through the use of fuel consumption-optimized Otto engines offering lowest emission levels (of the type ULEV, ultra-low emission vehicle, or EURO 4 standard), as compared to the relevant contributions to emission reduction and other targets offered by the fuel cell-driven automobiles.(orig./CB) [Deutsch] Das Umweltbundesamt hat die Brennstoffzellentechnik im Verkehr einer Kosten-Nutzen-Betrachtung unterzogen, um zu ermitteln, welche Vor- und Nachteile sie im Vergleich zu anderen Antriebskonzepten im Verkehr nach derzeitigem Wissensstand hat.

The characteristics and the film making process of polyether ether ketone (PEEK) resin, and the characteristics and the applications of PEEK film, are described. PEEK is aromatic polyketone with super thermal resistance. Though it is a crystalline polymer of which the crystallinity is controlled to 48% in a highest degree, it has also amorphous property, thus it shows unique property. The characteristics of PEEK resin are found in thermal resistance, incombusti-bility, transparency, chemical resistance, light resistance and radiation resistance. As for the film making process, casting method by T-die is generally adopted. The general properties of PEEK film are excellent in high thermal resistance, good electrical properties, chemical resistance, hydrolysis resistance, radiation resistance and imcombusti-bility. In the application of PEEK film, new development is expected in following fields; a high performance composite, flexible print substrate with high thermal resistance, insulating tape with thermal resistance, and a general film in the nuclear energy industry. 5 figs., 5 tabs.

Abstract A national filmsuggestived towards the ideasof nationalidentity. It can be labelled ‘national’ because the representation of national identity pertains to it. Usmar Ismail’s film was described as a national film because it presents genuine Indonesian. Through the textual analysis that discursive-performative understanding of national films can be achieved; an understanding that has become a myth in context to Usmar Ismail’s film.In order to clarified concepts of national film as well as to illustrate the discourse of national films in Usmar Ismail’s work, this analysis used JinHee Choi’s theory of national cinema. In which national film was theorized based on territorial, functional and relational factors. The findings of this analysis showed how the concept of national film in Usmar Ismail’s film actually struggles against the dominant discourse of its time particularly in terms of Usmar Ismail’s figure as a determining factor in establishing national films in Indonesia.   Keyword : National Cinema, Usmar Ismail, Darah dan Doa

Tribocontact between cam follower and roller tappet involves mixing and limiting friction states, which causes wear in the form of adhesive corrosion and pitting of surfaces. In cooperation with Purdue University, the influence of microgeometry (surface roughness) and macrogeometry (surface shape) was investigated in order to optimize lubrication for EHD lubrication conditions in contact, thus preventing wear and failure. This component project involves pressure and temperature measurements of cam follower and roller tappet tribocontact using flash-deposited thin film probes. The results are to provide information on design optimization. [German] Im Tribokontakt Nocken-Rollenstoessel herrschen vorwiegend Misch- und Grenzreibungszustaende. Dies fuehrt zu erheblichem Verschleiss in Form von adhaesiv bedingtem Fressen und Pittingbildung durch Oberflaechenzerruettung. Ziel dieses Forschungsvorhabens ist es, in Kooperation mit der Partnerhochschule ''Purdue University'' in den USA, den Einfluss der Mikrogeometrie (Oberflaechenrauheiten) und Makrogeometrie (Oberflaechenform) des Tribokontaktes Nocken-Rollenstoessel hinsichtlich des Betriebsverhaltens zu untersuchen, um Kenntnisse zur Verbesserung der Schmierbedingungen zu gewinnen, so dass im Kontakt elastohydrodynamische (EHD) Schmierungsverhaeltnisse realisiert werden und dadurch ein Ausfall aufgrund von Verschleiss ausgeschlossen wird. Im Rahmen dieses Teilvorhabens sollten Druck- und Temperaturmessungen mittels aufgedampfter Duennschichtaufnehmer im Tribokontakt, Nocken-Rollenstoessel, durchgefuehrt werden, um die theoretischen Forschungsarbeiten, welche in der Purdue University erarbeitet werden, zu untermauern. Beide Arbeiten werden somit neue Erkenntnisse zur konstruktiven Auslegung von verschleissfreien Nocken-Stoessel-Paarungen liefern. (orig.)

The development of screen-film mammography has resulted in the re-emergence of confidence, rather than fear, in mammography. When screen-film mammography is performed with state-of-the-art dedicated equipment utilizing vigorous breast compression and a ''soft'' x-ray beam for improved contrast, screen-film images are equivalent or superior to those of reduced-dose xeromammography and superior to those of nonscreen film mammography. Technological aids for conversion from xeromammographic or nonscreen film mammographic techniques to screen-film techniques have been described. Screen-film mammography should not be attempted until dedicated equipment has been obtained and the importance of vigorous compression has been understood

The first concentrates on the relation between exegesis and religious education because of the importance of reflecting on the concrete design of this special relation. The second centers what is indeed the centre of exegesis and religious education: the biblical text itself and the question of its real role and ways to handle it. Finally follows the presentation of a model of interaction with texts trying to equally respect all participants of this process. Simultaneously, this approach arranges a scope for the concrete biblical text allowing it to speak. This model is composed of three central steps: analysis (an exactly methodic procedure, interpretation (based on analysis, posing the question of meaning and appropriation (individually existential meaning.

Films by artists induce scholars to work across art, film and cultural history. Accordingly, this article adopts an interdisciplinary approach to the British-Nigerian artist Yinka Shonibare’s film Un Ballo in Maschera (2004). The film is grounded in Shonibare’s unique use of African-print fabric...... in conjunction with references to European cultural and political history, but the film is also – it is alleged – rooted in Black British cinema and the transnational postcolonialism which emerged in the UK of the 1980s. The article starts with a general introduction to Shonibare’s art and the colonial...... connotations of the African-print fabric, which are also central to the critique of power in Un Ballo in Maschera. Its critical agenda is then analysed and put into historical perspective by relating the film to Black British film. A comparison with the Black Audio Film Collective’s key work Handsworth Songs...

Pulverized bone specks and aluminum oxide specks were measured by hand into sizes ranging from 0.2 mm to 1.0 mm and then arranged in clusters. These clusters were superimposed on a human breast tissue phantom, and xeromammograms and screen-film mammograms of the clusters were made. The screen-film mammograms were digitized using a high-resolution laser scanner and then displayed on cathode ray tube (CRT) monitors. Six radiologists independently counted the microcalcifications on the xeromammograms, the screen-film mammograms, and the digitized film mammograms. The xeromammograms were examined with a magnifying glass; the screen-film images were examined with a magnifying glass and by hot light; and the digitized-film images were examined by electronic magnification and image processing. The bone speck size that corresponded to a mean 50% detectability level for each technique was as follows: xeromammography, 0.550 mm; digitized film, 0.573 mm; and screen-film, 0.661 mm. We postulate that electronic magnification and image processing with edge enhancement can improve the capability of screen-film mammography to enhance the detection of microcalcifications

A film cassette is mounted for reciprocating in the tunnel between an X-ray exposure position and a position in which the cassette is unloaded or loaded with film automatically. Unexposed films are dispensed one at a time into the cassette from a feed magazine at one end of the tunnel. After exposure, the film is ejected from the cassette into a receiving magazine at the same end of the tunnel. (Auth.)

Water-evaporation reduction by duplex films: application to the human tear film.

Science.gov (United States)

Cerretani, Colin F; Ho, Nghia H; Radke, C J

2013-09-01

Water-evaporation reduction by duplex-oil films is especially important to understand the physiology of the human tear film. Secreted lipids, called meibum, form a duplex film that coats the aqueous tear film and purportedly reduces tear evaporation. Lipid-layer deficiency is correlated with the occurrence of dry-eye disease; however, in-vitro experiments fail to show water-evaporation reduction by tear-lipid duplex films. We review the available literature on water-evaporation reduction by duplex-oil films and outline the theoretical underpinnings of spreading and evaporation kinetics that govern behavior of these systems. A dissolution-diffusion model unifies the data reported in the literature and identifies dewetting of duplex films into lenses as a key challenge to obtaining significant evaporation reduction. We develop an improved apparatus for measuring evaporation reduction by duplex-oil films including simultaneous assessment of film coverage, stability, and temperature, all under controlled external mass transfer. New data reported in this study fit into the larger body of work conducted on water-evaporation reduction by duplex-oil films. Duplex-oil films of oxidized mineral oil/mucin (MOx/BSM), human meibum (HM), and bovine meibum (BM) reduce water evaporation by a dissolution-diffusion mechanism, as confirmed by agreement between measurement and theory. The water permeability of oxidized-mineral-oil duplex films agrees with those reported in the literature, after correction for the presence of mucin. We find that duplex-oil films of bovine and human meibum at physiologic temperature reduce water evaporation only 6-8% for a 100-nm film thickness pertinent to the human tear film. Comparison to in-vivo human tear-evaporation measurements is inconclusive because evaporation from a clean-water surface is not measured and because the mass-transfer resistance is not characterized.

Effect of film size on drainage of foam and emulsion films

International Nuclear Information System (INIS)

Malhotra, A.K.; Wasan, D.T.

1987-01-01

All available theoretical analyses for the drainage of thin plane-parallel liquid films, such as those existing between two approaching liquid droplets or bubbles in the coalescence process, predict essentially the same dependence of rate of thinning of the intervening film on its size as is described by the Reynolds equation - that is, drainage time increases with the square of the film radius. Recently, the authors reported experimental data for both foam and emulsion films which showed that the measured drainage times increase with about a 0.8 power of the film radius, a value much smaller than the theoretically predicted value of 2.0. Here they present a hydrodynamic analysis to predict the experimentally observed effect of film size on the kinetics of thinning of emulsion and foam films. They extend the applicability of the Reynolds model by accounting for the flow in the Plateau borders as well as the London-van der Waals forces in the thin film phase. Their theoretical predictions are in good agreement with the experimental data on the dependence of drainage time of both foam and emulsion films on their radii

This invention relates to granular metal and metal oxide superconducting films formed by ion beam sputter deposition. Illustratively, the films comprise irregularly shaped, randomly oriented, small lead grains interspersed in an insulating lead oxide matrix. The films are hillock-resistant when subjected to thermal cycling and exhibit unusual josephson-type switching characteristics. Depending on the oxygen content, a film may behave in a manner similar to that of a plurality of series connected josephson junctions, or the film may have a voltage difference in a direction parallel to a major surface of the film that is capable of being switched from zero voltage difference to a finite voltage difference in response to a current larger than the critical current

Ag films deposited on Si and Ti: How the film-substrate interaction influences the nanoscale film morphology

Science.gov (United States)

Ruffino, F.; Torrisi, V.

2017-11-01

Submicron-thick Ag films were sputter deposited, at room temperature, on Si, covered by the native SiO2 layer, and on Ti, covered by the native TiO2 layer, under normal and oblique deposition angle. The aim of this work was to study the morphological differences in the grown Ag films on the two substrates when fixed all the other deposition parameters. In fact, the surface diffusivity of the Ag adatoms is different on the two substrates (higher on the SiO2 surface) due to the different Ag-SiO2 and Ag-TiO2 atomic interactions. So, the effect of the adatoms surface diffusivity, as determined by the adatoms-substrate interaction, on the final film morphology was analyzed. To this end, microscopic analyses were used to study the morphology of the grown Ag films. Even if the homologous temperature prescribes that the Ag film grows on both substrates in the zone I described by the structure zone model some significant differences are observed on the basis of the supporting substrate. In the normal incidence condition, on the SiO2/Si surface a dense close-packed Ag film exhibiting a smooth surface is obtained, while on the TiO2/Ti surface a more columnar film morphology is formed. In the oblique incidence condition the columnar morphology for the Ag film occurs both on SiO2/Si and TiO2/Ti but a higher porous columnar film is obtained on TiO2/Ti due to the lower Ag diffusivity. These results indicate that the adatoms diffusivity on the substrate as determined by the adatom-surface interaction (in addition to the substrate temperature) strongly determines the final film nanostructure.

To research surface structure of thin film and multilayer film by neutron, a neutron diffuse scattering analysis code using DWBA (Distorted-Wave Bron Approximation) principle was developed. Subjects using this code contain the surface and interface properties of solid/solid, solid/liquid, liquid/liquid and gas/liquid, and metal, magnetism and polymer thin film and biomembran. The roughness of surface and interface of substance shows fractal self-similarity and its analytical model is based on DWBA theory by Sinha. The surface and interface properties by diffuse scattering are investigated on the basis of the theoretical model. The calculation values are proved to be agreed with the experimental values. On neutron diffuse scattering by thin film, roughness of surface of thin film, correlation function, neutron propagation by thin film, diffuse scattering by DWBA theory, measurement model, SDIFFF (neutron diffuse scattering analysis program by thin film) and simulation results are explained.

Also examines the benefits, and possible risks, associated with waste recycling projects of this kind. The results of the investigations show that compost recycling for emission-protection purposes can be used to support the emission-protection measures previously deployed at opencast mines in the Rhine lignite basin, including the grassing-over of former mine sites. Such measures are now considered to be technically feasible, environmentally compatible and lawful, and indeed are considered necessary in some circumstances. (orig.)

Full Text Available The articles here presented are representative of the debates about the various transformational aspects of film studies, fostering the discussion about the transformations and interactions between national and international narrative forms, the interrelations between film and literature, and film with other media. The critical perspectives here presented range from an emphasis on cultural materialism, dialogism, reception theory, deconstructionism, narrative studies to film aesthetics or film genre, and can be grouped in three major interrelated areas of film studies: adaptation studies, representation and aesthetics, and film and other media. All of them enable a critical perspective as regards the fluidity of the boundaries separating film from other media, such as literature, television, DVDs, and video games, as newer narrative forms that are incorporated by film, and the transformations in terms of aesthetics and forms of representation in contemporary film and media (the transgeneric nature of film, the interrelations between national and international cinemas, and the demands for a broader perception of the overwhelming mediations of the image in our contemporary society. Moreover, the articles are inserted within recent critical debates on adaptation, digital media and national and transnational cinema (Naremore, Sobchack, Druckery and Williams. All articles combine important theoretical concerns with the analysis of specific films. Robert Stam's “Teoria e Prática da Adaptação: da Fidelidade à Intertextualidade” (“Theory and the practice of adaptation: from fidelity to intertextuality” offers a rich perspective on the issue of adaptation in its relationship with critical theory. He analyses the changing critical views on adaptation, which go from the priority given to the canonic literary text, as an origin, to a more fluid, intertextual and dialogical approach to film adaptation.

The effects of the deposition temperature on the growth characteristics of the ZnO films were studied for film bulk acoustic wave resonator (FBAR) device applications. All films were deposited using a radio frequency magnetron sputtering technique. It was found that the growth characteristics of ZnO films have a strong dependence on the deposition temperature from 25 to 350 deg. C. ZnO films deposited below 200 deg. C exhibited reasonably good columnar grain structures with highly preferred c-axis orientation while those above 200 deg. C showed very poor columnar grain structures with mixed-axis orientation. This study seems very useful for future FBAR device applications

Thin Film Microbatteries

Thin film batteries are built layer by layer by vapor deposition. The resulting battery is formed of parallel plates, much as an ordinary battery construction, just much thinner. The figure (Fig. 1) shows an example of a thin film battery layout where films are deposited symmetrically onto both sides of a supporting substrate. The full stack of films is only 10 to 15 (micro)m thick, but including the support at least doubles the overall battery thickness. When the support is thin, the entire battery can be flexible. At least six companies have commercialized or are very close to commercializing such all-solid-state thin film batteries and market research predicts a growing market and a variety of applications including sensors, RFID tags, and smarter cards. In principle with a large deposition system, a thin film battery might cover a square meter, but in practice, most development is targeting individual cells with active areas less than 25 cm 2 . For very small battery areas, 2 , microfabrication processes have been developed. Typically the assembled batteries have capacities from 0.1 to 5 mAh. The operation of a thin film battery is depicted in the schematic diagram (Fig. 2). Very simply, when the battery is allowed to discharge, a Li + ion migrates from the anode to the cathode film by diffusing through the solid electrolyte. When the anode and cathode reactions are reversible, as for an intercalation compound or alloy, the battery can be recharged by reversing the current. The difference in the electrochemical potential of the lithium determines the cell voltage. Most of the thin films used in current commercial variations of this thin film battery are deposited in vacuum chambers by RF and DC magnetron sputtering and by thermal evaporation onto unheated substrates. In addition, many publications report exploring a variety of other physical and chemical vapor deposition processes, such as pulsed laser deposition, electron cyclotron resonance sputtering, and

One-step aerosol synthesis of nanoparticle agglomerate films: simulation of film porosity and thickness

International Nuclear Information System (INIS)

Maedler, Lutz; Lall, Anshuman A; Friedlander, Sheldon K

2006-01-01

A method is described for designing nanoparticle agglomerate films with desired film porosity and film thickness. Nanoparticle agglomerates generated in aerosol reactors can be directly deposited on substrates to form uniform porous films in one step, a significant advance over existing technologies. The effect of agglomerate morphology and deposition mechanism on film porosity and thickness are discussed. Film porosity was calculated for a given number and size of primary particles that compose the agglomerates, and fractal dimension. Agglomerate transport was described by the Langevin equation of motion. Deposition enhancing forces such as thermophoresis are incorporated in the model. The method was validated for single spherical particles using previous theoretical studies. An S-shape film porosity dependence on the particle Peclet number typical for spherical particles was also observed for agglomerates, but films formed from agglomerates had much higher porosities than films from spherical particles. Predicted film porosities compared well with measurements reported in the literature. Film porosities increased with the number of primary particles that compose an agglomerate and higher fractal dimension agglomerates resulted in denser films. Film thickness as a function of agglomerate deposition time was calculated from the agglomerate deposition flux in the presence of thermophoresis. The calculated film thickness was in good agreement with measured literature values. Thermophoresis can be used to reduce deposition time without affecting the film porosity

A strategy is proposed for the dedicated interpretation of possible radiographic plain film signs that are suspicious for indicating child abuse. For each sign, the features `PRO` raise the question of abuse, while radiographic or clinical findings `CON` suggest an alternate explanation. Birth trauma, oesteogenesis imperfecta, rescue trauma, and metastatic neuroblastoma are among the many entities cited. A triad of situations may lead a radiologist to look systematically for changes from abuse; a triad of resolutions may result from the search. Periosteal reaction is the major factor in dating of fractures; physiologic periosteal reaction of infancy and periosteal reaction from previous fracture must be considered when so dating fractures. (orig.) [Deutsch] Es wird eine Strategie fuer die genaue Interpretation roentgenologischer Befunde, die auf eine Kindesmisshandlung hindeuten koennen, vorgeschlagen. Fuer jeden Befund werfen die unter `PRO` aufgefuehrten Merkmale die Frage nach einer Kindesmisshandlung auf, waehrend radiologische und klinische Befunde unter `CON` andere Erklaerungen nahelegen. Geburtstrauma, Osteogenesis imperfecta, Rettungstrauma und metastasierendes Neuroblastom sind unter den vielen zitierten Differentialdiagnosen. Drei moegliche Situationen koennen den Radiologen dazu veranlassen, systematisch nach Zeichen einer Kindesmisshandlung zu suchen, 3 moegliche Loesungen koennen aus dieser Suche hervorgehen. Eine Periostreaktion ist ein Kardinalbefund zur Datierung von Frakturen. Physiologische Periostreaktionen im fruehen Kindesalter und Periostreaktionen durch fruehere Frakturen muessen bei einer solchen Datierung von Frakturen mitbedacht werden. (orig.)

Evaluation and mitigation of potential errors in radiochromic film dosimetry due to film curvature at scanning.

Science.gov (United States)

Palmer, Antony L; Bradley, David A; Nisbet, Andrew

2015-03-08

This work considers a previously overlooked uncertainty present in film dosimetry which results from moderate curvature of films during the scanning process. Small film samples are particularly susceptible to film curling which may be undetected or deemed insignificant. In this study, we consider test cases with controlled induced curvature of film and with film raised horizontally above the scanner plate. We also evaluate the difference in scans of a film irradiated with a typical brachytherapy dose distribution with the film naturally curved and with the film held flat on the scanner. Typical naturally occurring curvature of film at scanning, giving rise to a maximum height 1 to 2 mm above the scan plane, may introduce dose errors of 1% to 4%, and considerably reduce gamma evaluation passing rates when comparing film-measured doses with treatment planning system-calculated dose distributions, a common application of film dosimetry in radiotherapy. The use of a triple-channel dosimetry algorithm appeared to mitigate the error due to film curvature compared to conventional single-channel film dosimetry. The change in pixel value and calibrated reported dose with film curling or height above the scanner plate may be due to variations in illumination characteristics, optical disturbances, or a Callier-type effect. There is a clear requirement for physically flat films at scanning to avoid the introduction of a substantial error source in film dosimetry. Particularly for small film samples, a compression glass plate above the film is recommended to ensure flat-film scanning. This effect has been overlooked to date in the literature.

A ceramic composite thin film or layer includes individual graphene oxide and/or electrically conductive graphene sheets dispersed in a ceramic (e.g. silica) matrix. The thin film or layer can be electrically conductive film or layer depending the amount of graphene sheets present. The composite films or layers are transparent, chemically inert and compatible with both glass and hydrophilic SiOx/silicon substrates. The composite film or layer can be produced by making a suspension of graphene oxide sheet fragments, introducing a silica-precursor or silica to the suspension to form a sol, depositing the sol on a substrate as thin film or layer, at least partially reducing the graphene oxide sheets to conductive graphene sheets, and thermally consolidating the thin film or layer to form a silica matrix in which the graphene oxide and/or graphene sheets are dispersed.

Solid thin film materials for use in thin film charge-coupled devices

1983-01-01

Solid thin films deposited by vacuum deposition were evaluated to ascertain their effectiveness for use in the manufacturing of charge-coupled devices (CCDs). Optical and electrical characteristics of tellurium and Bi 2 Te 3 solid thin films were obtained in order to design and to simulate successfully the operation of thin film (TF) CCDs. In this article some of the material differences between single-crystal material and the island-structured thin film used in TFCCDs are discussed. The electrical parameters were obtained and tabulated, e.g. the mobility, conductivity, dielectric constants, permittivity, lifetime of holes and electrons in the thin films and drift diffusion constants. The optical parameters were also measured and analyzed. After the design was complete, experimental TFCCDs were manufactured and were successfully operated utilizing the aforementioned solid thin films. (Auth.)

[Application of biodegradable plastic film to reduce plastic film residual pollution in Chinese agriculture].

Science.gov (United States)

Yan, Changrong; He, Wenqing; Xue, Yinghao; Liu, Enke; Liu, Qin

2016-06-25

Plastic film has become an important agriculture production material in recent years. Over the past three decades, the amount and application area of plastic film have increased steadily, and in 2014, which are 1.4 million tons and more than 180 million hm² respectively. It plays a key role for ensuring the supply of agricultural goods in China. Meanwhile, plastic film residual pollution becomes more and more serious, and in some regions, the amount of plastic film residues has reached over 250 kg/hm². In part of the Northwest region, soil structure of farmland has been destroyed by plastic film residues and then crop growth and farming operations were suppressed. It is recognized as a good choice to replace plastic film with biodegradable plastic film, an effective measure to solve the plastic film residue pollution. Now, it is in a critical stage of study and assessment of biodegradable plastic film in China and fortunately some biodegradable plastic films show effects in the production of potatoes, peanuts and tobacco. Overall, a series of challenges has still been faced by the biodegradable plastic film, mainly including improving the quality of biodegradable plastic products, such as tensile strength, flexibility, improving the controllability of rupture and degradation, enhancing the ability of increasing soil temperature and preserving soil moisture, and to satisfy the demand of crops production with mulching. In addition, it is essential to reduce the cost of the biodegradable film and promote the application of biodegradable film on large-scale. With the development of biodegradable plastic technology and agricultural production environment, the application of the biodegradable film will have a good future.

Meteor Film Recording with Digital Film Cameras with large CMOS Sensors

Slansky, P. C.

2016-12-01

In this article the author combines his professional know-how about cameras for film and television production with his amateur astronomy activities. Professional digital film cameras with high sensitivity are still quite rare in astronomy. One reason for this may be their costs of up to 20 000 and more (camera body only). In the interim, however,consumer photo cameras with film mode and very high sensitivity have come to the market for about 2 000 EUR. In addition, ultra-high sensitive professional film cameras, that are very interesting for meteor observation, have been introduced to the market. The particular benefits of digital film cameras with large CMOS sensors, including photo cameras with film recording function, for meteor recording are presented by three examples: a 2014 Camelopardalid, shot with a Canon EOS C 300, an exploding 2014 Aurigid, shot with a Sony alpha7S, and the 2016 Perseids, shot with a Canon ME20F-SH. All three cameras use large CMOS sensors; "large" meaning Super-35 mm, the classic 35 mm film format (24x13.5 mm, similar to APS-C size), or full format (36x24 mm), the classic 135 photo camera format. Comparisons are made to the widely used cameras with small CCD sensors, such as Mintron or Watec; "small" meaning 12" (6.4x4.8 mm) or less. Additionally, special photographic image processing of meteor film recordings is discussed.

Effect of diffraction and film-thickness gradients on wafer-curvature measurements of thin-film stress

International Nuclear Information System (INIS)

Breiland, W.G.; Lee, S.R.; Koleske, D.D.

2004-01-01

When optical measurements of wafer curvature are used to determine thin-film stress, the laser beams that probe the sample are usually assumed to reflect specularly from the curved surface of the film and substrate. Yet, real films are not uniformly thick, and unintended thickness gradients produce optical diffraction effects that steer the laser away from the ideal specular condition. As a result, the deflection of the laser in wafer-curvature measurements is actually sensitive to both the film stress and the film-thickness gradient. We present a Fresnel-Kirchhoff optical diffraction model of wafer-curvature measurements that provides a unified description of these combined effects. The model accurately simulates real-time wafer-curvature measurements of nonuniform GaN films grown on sapphire substrates by vapor-phase epitaxy. During thin-film growth, thickness gradients cause the reflected beam to oscillate asymmetrically about the ideal position defined by the stress-induced wafer curvature. This oscillating deflection has the same periodicity as the reflectance of the growing film, and the deflection amplitude is a function of the film-thickness gradient, the mean film thickness, the wavelength distribution of the light source, the illuminated spot size, and the refractive indices of the film and substrate. For typical GaN films grown on sapphire, misinterpretation of these gradient-induced oscillations can cause stress-measurement errors that approach 10% of the stress-thickness product; much greater errors occur in highly nonuniform films. Only transparent films can exhibit substantial gradient-induced deflections; strongly absorbing films are immune

Films containing microencapsulated cinnamon oil (CO) were developed using a large-scale production system to protect against the Indian meal moth (Plodia interpunctella). CO at concentrations of 0%, 0.8%, or 1.7% (w/w ink mixture) was microencapsulated with polyvinyl alcohol. The microencapsulated CO emulsion was mixed with ink (47% or 59%, w/w) and thinner (20% or 25%, w/w) and coated on polypropylene (PP) films. The PP film was then laminated with a low-density polyethylene (LDPE) film on the coated side. The film with microencapsulated CO at 1.7% repelled P. interpunctella most effectively. Microencapsulation did not negatively affect insect repelling activity. The release rate of cinnamaldehyde, an active repellent, was lower when CO was microencapsulated than that in the absence of microencapsulation. Thermogravimetric analysis exhibited that microencapsulation prevented the volatilization of CO. The tensile strength, percentage elongation at break, elastic modulus, and water vapor permeability of the films indicated that microencapsulation did not affect the tensile and moisture barrier properties (P > 0.05). The results of this study suggest that effective films for the prevention of Indian meal moth invasion can be produced by the microencapsulation of CO using a large-scale film production system. Low-density polyethylene-laminated polypropylene films printed with ink incorporating microencapsulated cinnamon oil using a large-scale film production system effectively repelled Indian meal moth larvae. Without altering the tensile and moisture barrier properties of the film, microencapsulation resulted in the release of an active repellent for extended periods with a high thermal stability of cinnamon oil, enabling commercial film production at high temperatures. This anti-insect film system may have applications to other food-packaging films that use the same ink-printing platform. © 2018 Institute of Food Technologists®.

P-type CuxS thin films: Integration in a thin film transistor structure

Nunes de Carvalho, C.; Parreira, P.; Lavareda, G.; Brogueira, P.; Amaral, A.

2013-01-01

Cu x S thin films, 80 nm thick, are deposited by vacuum thermal evaporation of sulfur-rich powder mixture, Cu 2 S:S (50:50 wt.%) with no intentional heating of the substrate. The process of deposition occurs at very low deposition rates (0.1–0.3 nm/s) to avoid the formation of Cu or S-rich films. The evolution of Cu x S films surface properties (morphology/roughness) under post deposition mild annealing in air at 270 °C and their integration in a thin film transistor (TFT) are the main objectives of this study. Accordingly, Scanning Electron Microscopy studies show Cu x S films with different surface morphologies, depending on the post deposition annealing conditions. For the shortest annealing time, the Cu x S films look to be constructed of grains with large dimension at the surface (approximately 100 nm) and consequently, irregular shape. For the longest annealing time, films with a fine-grained surface are found, with some randomly distributed large particles bound to this fine-grained surface. Atomic Force Microscopy results indicate an increase of the root-mean-square roughness of Cu x S surface with annealing time, from 13.6 up to 37.4 nm, for 255 and 345 s, respectively. The preliminary integration of Cu x S films in a TFT bottom-gate type structure allowed the study of the feasibility and compatibility of this material with the remaining stages of a TFT fabrication as well as the determination of the p-type characteristic of the Cu x S material. - Highlights: • Surface properties of annealed Cu x S films. • Variation of conductivity with annealing temperatures of Cu x S films. • Application of evaporated Cu x S films in a thin film transistor (TFT) structure. • Determination of Cu x S p-type characteristic from TFT behaviour

Full text of publication follows: Film boiling heat transfer has application to the safe operation of water-cooled nuclear reactors under fault conditions and it has been studied using nickel-plated copper specimens in transient and steady state experiments. In the transient tests the specimens were held in a water flow; in the steady state investigation a specimen was mounted in an essentially quiescent pool of water. The transient investigation was conducted on two spheres with different diameters, two cylindrical specimens of different lengths in parallel flow, a short cylinder in cross flow and two flat plates with different lengths. The heat transfer coefficient, vapour film thickness (which was estimated from the heat transfer coefficient) and heat flux followed a similar behaviour with changing experimental conditions for all specimens studied. The heat transfer coefficient increased and the vapour film thickness and heat flux decreased as the specimen temperature decreased. As the water subcooling increased the heat transfer coefficient and the heat flux increased while the vapour film thickness decreased. The water velocity was found to have little influence on the film boiling heat transfer results except for the short cylinder in cross flow. The sphere diameter was found to affect the heat transfer results; the heat transfer coefficient and the heat flux were larger, for the larger sphere. No significant effect of the cylinder length on the heat transfer data was observed. However, the heat transfer coefficient was higher (and the average vapour film thinner) for the longer plate than for the shorter plate. Three vapour/liquid interface types were observed namely: 'smooth', 'rippled' and 'turbulent' depending largely on specimen and water temperatures. For all specimens, the maximum heat transfer coefficient, minimum heat flux and minimum film boiling temperature, occurring just before vapour film collapse, were found to increase as the water subcooling

Film sheet cassette

International Nuclear Information System (INIS)

1981-01-01

A novel film sheet cassette is described for handling CAT photographic films under daylight conditions and facilitating their imaging. A detailed description of the design and operation of the cassette is given together with appropriate illustrations. The resulting cassette is a low-cost unit which is easily constructed and yet provides a sure light-tight seal for the interior contents of the cassette. The individual resilient fingers on the light-trap permit the ready removal of the slide plate for taking pictures. The stippled, non-electrostatic surface of the pressure plate ensures an air layer and free slidability of the film for removal and withdrawal of the film sheet. The advantage of the daylight system is that a darkroom need not be used for inserting and removing the film in and out of the cassette resulting in a considerable time saving. (U.K.)

Thin films for precision optics

The technology of producing dielectric and/or metallic thin films for high precision optical components is discussed. Computer programs were developed in order to calculate and register, graphically, reflectance and transmittance spectra of multi-layer films. The technology of vacuum evaporation of several materials was implemented in our thin-films laboratory; various films for optics were then developed. The possibility of first calculate film characteristics and then produce the film is of great advantage since it reduces the time required to produce a new type of film and also reduces the cost of the project.

The high material and processing costs associated with single-crystal and polycrystalline silicon wafers that are commonly used in photovoltaic cells render these modules expensive. This presentation described thin-film solar cell technology as a promising alternative to silicon solar cell technology. Cadmium telluride (CdTe) thin films along with copper, indium, gallium, and selenium (CIGS) thin films have become the leaders in this field. Their large optical absorption coefficient can be attributed to a direct energy gap that allows the use of thin layers (1-2 {mu}m) of active material. The efficiency of thin-film solar cell devices based on CIGS is 20 per cent, compared to 16.7 per cent for thin-film solar cell devices based on CdTe. IBM recently reported an efficiency of 9.7 per cent for a new type of inorganic thin-film solar cell based on a Cu{sub 2}ZnSn(S, Se){sub 4} compound. The efficiency of an organic thin-film solar cell is 7.9 per cent. This presentation included a graph of PV device efficiencies and discussed technological advances in non-vacuum deposited, CIGS-based thin-film solar cells. 1 fig.

Film selection in medical radiology

International Nuclear Information System (INIS)

Bor, Dogan

1988-01-01

Importing of medical imaging films is the responsibility of Turkish Red Croscend, but some institutions have currently started to import their own films. Because of the different resources in individual departments throughout Turkey, a general purpose medical film is imported by Turkish Red Croscend. This kind of film has the advantage to tolerate some technical faults related to the exposure, dark room and processing conditions and still reveals the necessary image quality. In addition to general purpose film, many companies produce special used films which improve some film characteristics in order to have a better image. The initial results of a project already started by Turkish Atomic Energy Authority showed that some other technical reasons prevent obtaining films with optimum quality. The film is the last step of diagnostic procedure and not only gives necessary clinical information, but also visualizes all the problems related to the lock of the calibration of X-ray system and dark room processing conditions. Because of these reasons, many people hold the film responsible for every technical problem. During the selection of the best film among the different companies, institutions have to fulfill some prerequisites at the beginning and than evaluate the quantitative results obtained from measurements according to their clinical purposes. It is the subject of this paper to show how to use film parameter as a comparison to different types of films measured with light sensitometry method. The dark room and processing problems which adversely effect the results are also given. The requirements for the best film selection both for general and special purposes are also evaluated. The extent of this paper is limited only to films using radiology and does not cover the types used in other imaging areas

Gafchromic {sup registered} EBT2 film is a widely used dosimetric tool for quality assurance in radiation therapy. In 2012 EBT3 was presented as a replacement for EBT2 films. The symmetric structure of EBT3 films to reduce face-up/down dependency as well as the inclusion of a matte film surface to frustrate Newton Ring artifacts present the most prominent improvements of EBT3 films. The aim of this study was to investigate the characteristics of EBT3 films, to benchmark the films against the known EBT2-features and to evaluate the dosimetric behavior over a time period greater than 6 months. All films were irradiated to clinical photon beams (6MV, 10MV and 18MV) on an Elekta Synergy Linac equipped with a Beam Modulator MLC in solid water phantom slabs. Film digitalization was done with a flatbed transparency scanner (Type Epson Expression 1680 Pro). MATLAB {sup registered} was used for further statistical calculations and image processing. The investigations on post-irradiation darkening, film orientation, film uniformity and energy dependency resulted in negligible differences between EBT2 and EBT3 film. A minimal improvement in face-up/down dependence was found for EBT3. The matte film surface of EBT3 films turned out to be a practical feature as Newton rings could be eliminated completely. Considering long-term behavior (> 6 months) a shift of the calibration curve for EBT2 and EBT3 films due to changes in the dynamic response of the active component was observed. In conclusion, the new EBT3 film yields comparable results to its predecessor EBT2. The general advantages of radiochromic film dosimeters are completed by high film homogeneity, low energy dependence for the observed energy range and a minimized face-up/down dependence. EBT2 dosimetry-protocols can also be used for EBT3 films, but the inclusion of periodical recalibration-interval (e.g. once a quarter) is recommended for protocols of both film generations. (orig.)

Oral films, namely buccal mucoadhesive films and orodispersible films represent innovative formulations for administration of a wide range of drugs. Oral films show many advantageous properties and are intended for systemic drug delivery or for local treatment of the oral mucosa. In both cases, the film represents a thin layer, which could be intended to adhere to the oral mucosa by means of mucoadhesion; or to rapid dissolution and subsequent swallowing without the need of liquid intake, in the case of orodispersible films. Main constitutive excipients are film-forming polymers, which must in the case of mucoadhesive forms remain on the mucosa within the required time interval. Oral films are currently available on the pharmaceutical market and could compete with conventional oral dosage forms in the future. oral cavity oral films buccal mucoadhesive films orodispersible films film-forming polymers.

A series of SiO{sub 2} films with thickness range 1-600 nm have been deposited on crystal silicon (c-Si) substrates by electron beam evaporation (EBE) method. Variable-angle spectroscopic ellipsometry (VASE) in combination with a two-film model (ambient-oxide-interlayer substrate) was used to determine the optical constants and thicknesses of the investigated films. The refractive indices of SiO{sub 2} films thicker than 60 nm are close to those of bulk SiO{sub 2}. For the thin films deposited at the rate of {approx}1.0 nm s{sup -1}, the refractive indices increase with decreasing thickness from {approx}60 to {approx}10 nm and then drop sharply with decreasing thickness below {approx}10 nm. However, for thin films deposited at the rates of {approx}0.4 and {approx}0.2 nm s{sup -1}, the refractive indices monotonically increase with decreasing thickness below 60 nm. The optical constants of the ultrathin film depend on the morphology of the film, the stress exerted on the film, as well as the stoichiometry of the oxide film.

Diamond-like carbon (DLC) films, which are amorphous carbon films, have been used as hard-coating films for protecting the surface of mechanical parts. Nitrogen-containing DLC (N-DLC) films are expected as conductive hard-coating materials. N-DLC films are expected in applications such as protective films for contact pins, which are used in the electrical check process of integrated circuit chips. In this study, N-DLC films are prepared using the T-shaped filtered arc deposition (T-FAD) method, and film properties are investigated. Film hardness and film density decreased when the N content increased in the films because the number of graphite structures in the DLC film increased as the N content increased. These trends are similar to the results of a previous study. The electrical resistivity of N-DLC films changed from 0.26 to 8.8 Ω cm with a change in the nanoindentation hardness from 17 to 27 GPa. The N-DLC films fabricated by the T-FAD method showed high mechanical hardness and low electrical resistivity.

Full Text Available Trotz der überwältigenden öffentlichen wie wissenschaftlichen Resonanz, auf die der Nudge-Ansatz von Thaler und Sunstein gestoßen ist, bleiben die genauen Konturen dieses Theorie und Policyvorschlages unscharf. So ist an vielen Stellen unklar, worin die spezifische Differenz gegenüber klassischen Formen der Verhaltenssteuerung liegen soll. Für eine Bewertung des Ansatzes in seinen Vorzügen und Nachteilen gegenüber klassischen Steuerungsformen ist eine solche klärende Einordnung jedoch notwendige Vorbedingung. Der Aufsatz arbeitet daher die bestehenden Definitions- und Abgrenzungsprobleme von „Nudge“ und „Libertärem Paternalismus“ heraus und plädiert sodann für einen Kernbegriff von „Nudge“, der dessen Extension einschränkt, um ihn als originären und eigenständigen Vorschlag einzugrenzen. Ein so präzisiertes Verständnis von Nudge wird dann hinsichtlich seiner Eigenschaften sowie der Gemeinsamkeiten und Unterschiede zu klassischen Formen der Verhaltenssteuerung ins Verhältnis gesetzt.

In this study, we present three significant artifacts that have the potential to negatively impact the accuracy and precision of film dosimetry measurements made using GAFCHROMIC[reg] EBT radiochromic film when read out with CCD flatbed scanners. Films were scanned using three commonly employed instruments: a Macbeth TD932 spot densitometer, an Epson Expression 1680 CCD array scanner, and a Microtek ScanMaker i900 CCD array scanner. For the two scanners we assessed the variation in optical density (OD) of GAFCHROMIC EBT film with scanning bed position, angular rotation of the film with respect to the scan line direction, and temperature inside the scanner due to repeated scanning. Scanning uniform radiochromic films demonstrated a distinct bowing effect in profiles in the direction of the CCD array with a nonuniformity of up to 17%. Profiles along a direction orthogonal to the CCD array demonstrated a 7% variation. A strong angular dependence was found in measurements made with the flatbed scanners; the effect could not be reproduced with the spot densitometer. An IMRT quality assurance film was scanned twice rotating the film 90 deg. between the scans. For films scanned on the Epson scanner, up to 12% variation was observed in unirradiated EBT films rotated between 0 deg. and 90 deg. , which decreased to approximately 8% for EBT films irradiated to 300 cGy. Variations of up to 80% were observed for films scanned with the Microtek scanner. The scanners were found to significantly increase the film temperature with repeated scanning. Film temperature between 18 and 33 deg. C caused OD changes of approximately 7%. Considering these effects, we recommend adherence to a strict scanning protocol that includes: maintaining the orientation of films scanned on flatbed scanners, limiting scanning to the central portion of the scanner bed, and limiting the number of consecutive scans to minimize changes in OD caused by film heating

Graphical abstract: The effect of O{sub 2} plasma treatment on the surface and the work function of ITO films. - Highlights: • ITO films were prepared on the glass substrate by RF magnetron sputtering method. • Effects of O{sub 2} plasma treatment on the properties of ITO films were investigated. • The work function of ITO film was changed from 4.67 to 5.66 eV by plasma treatment. - Abstract: The influence of oxygen plasma treatment on the electro-optical and structural properties of indium-tin-oxide films deposited by radio frequency magnetron sputtering method were investigated. The films were exposed at different O{sub 2} plasma powers and for various durations by using the plasma enhanced chemical vapor deposition (PECVD) system. The resistivity of the ITO films was almost constant, regardless of the plasma treatment conditions. Although the optical transmittance of ITO films was little changed by the plasma power, the prolonged treatment slightly increased the transmittance. The work function of ITO film was changed from 4.67 eV to 5.66 eV at the plasma treatment conditions of 300 W and 60 min.

Host thin films incorporating nanoparticles

Science.gov (United States)

Qureshi, Uzma

The focus of this research project was the investigation of the functional properties of thin films that incorporate a secondary nanoparticulate phase. In particular to assess if the secondary nanoparticulate material enhanced a functional property of the coating on glass. In order to achieve this, new thin film deposition methods were developed, namely use of nanopowder precursors, an aerosol assisted transport technique and an aerosol into atmospheric pressure chemical vapour deposition system. Aerosol assisted chemical vapour deposition (AACVD) was used to deposit 8 series of thin films on glass. Five different nanoparticles silver, gold, ceria, tungsten oxide and zinc oxide were tested and shown to successfully deposit thin films incorporating nanoparticles within a host matrix. Silver nanoparticles were synthesised and doped within a titania film by AACVD. This improved solar control properties. A unique aerosol assisted chemical vapour deposition (AACVD) into atmospheric pressure chemical vapour deposition (APCVD) system was used to deposit films of Au nanoparticles and thin films of gold nanoparticles incorporated within a host titania matrix. Incorporation of high refractive index contrast metal oxide particles within a host film altered the film colour. The key goal was to test the potential of nanopowder forms and transfer the suspended nanopowder via an aerosol to a substrate in order to deposit a thin film. Discrete tungsten oxide nanoparticles or ceria nanoparticles within a titanium dioxide thin film enhanced the self-cleaning and photo-induced super-hydrophilicity. The nanopowder precursor study was extended by deposition of zinc oxide thin films incorporating Au nanoparticles and also ZnO films deposited from a ZnO nanopowder precursor. Incorporation of Au nanoparticles within a VO: host matrix improved the thermochromic response, optical and colour properties. Composite VC/TiC and Au nanoparticle/V02/Ti02 thin films displayed three useful

A method of making carbon thin films comprises depositing a catalyst on a substrate, depositing a hydrocarbon in contact with the catalyst and pyrolyzing the hydrocarbon. A method of controlling a carbon thin film density comprises etching a cavity into a substrate, depositing a hydrocarbon into the cavity, and pyrolyzing the hydrocarbon while in the cavity to form a carbon thin film. Controlling a carbon thin film density is achieved by changing the volume of the cavity. Methods of making carbon containing patterned structures are also provided. Carbon thin films and carbon containing patterned structures can be used in NEMS, MEMS, liquid chromatography, and sensor devices.

Ellipsometry of anodic film growth

Energy Technology Data Exchange (ETDEWEB)

Smith, C.G.

1978-08-01

An automated computer interpretation of ellisometer measurements of anodic film growth was developed. Continuous mass and charge balances were used to utilize more fully the time dependence of the ellipsometer data and the current and potential measurements. A multiple-film model was used to characterize the growth of films which proceeds via a dissolution--precipitation mechanism; the model also applies to film growth by adsorption and nucleation mechanisms. The characteristic parameters for film growth describe homogeneous and heterogeneous crystallization rates, film porosities and degree of hydration, and the supersaturation of ionic species in the electrolyte. Additional descriptions which may be chosen are patchwise film formation, nonstoichiometry of the anodic film, and statistical variations in the size and orientation of secondary crystals. Theories were developed to describe the optical effects of these processes. An automatic, self-compensating ellipsometer was used to study the growth in alkaline solution of anodic films on silver, cadmium, and zinc. Mass-transport conditions included stagnant electrolyte and forced convection in a flow channel. Multiple films were needed to characterize the optical properties of these films. Anodic films grew from an electrolyte supersatuated in the solution-phase dissolution product. The degree of supersaturation depended on transport conditions and had a major effect on the structure of the film. Anodic reaction rates were limited by the transport of charge carriers through a primary surface layer. The primary layers on silver, zinc, and cadmium all appeared to be nonstoichiometric, containing excess metal. Diffusion coefficients, transference numbers, and the free energy of adsorption of zinc oxide were derived from ellipsometer measurements. 97 figures, 13 tables, 198 references.

In order to quantitatively interpret film radiographs, it is necessary to digitize, interpret, and display the images. Our integrated system of quantitative radiography displays accurate, high-resolution pseudo-color images in units of density. We characterize approximately 10,000 parts per year in hundreds of different configurations and compositions with this system. This report discusses: the method; film processor monitoring and control; verifying film and processor performance; and correction of scatter effects

Radiographic film orientation in radiotherapy dosimetry

International Nuclear Information System (INIS)

Suchowerska, N.; Davison, A.; Drew, J.; Metcalfe, P.

1996-01-01

Since the discovery of x-rays, film has been used as a detection medium for radiation. More recently radiographic film has become established as a practical tool for the measurement of dose distribution in radiotherapy. The accuracy and reproducibility of film dosimetry depends on photon energy, processing conditions and film plane orientation. The relationship between photon energy, processing conditions and film dosimetry accuracy has been studied. The role of film plane orientation is still controversial. The current work aims to clarify the effects film plane orientation has on film dosimetry. Poster 205. (author)

Film beyond boundaries: film, migrant narratives and other media

Full Text Available The articles here presented are representative of the debates about the various transformational aspects of film studies, fostering the discussion about the transformations and interactions between national and international narrative forms, the interrelations between film and literature, and film with other media. The critical perspectives here presented range from an emphasis on cultural materialism, dialogism, reception theory, deconstructionism, narrative studies to film aesthetics or film genre, and can be grouped in three major interrelated areas of film studies: adaptation studies, representation and aesthetics, and film and other media. All of them enable a critical perspective as regards the fluidity of the boundaries separating film from other media, such as literature, television, DVDs, and video games, as newer narrative forms that are incorporated by film, and the transformations in terms of aesthetics and forms of representation in contemporary film and media (the transgeneric nature of film, the interrelations between national and international cinemas, and the demands for a broader perception of the overwhelming mediations of the image in our contemporary society. Moreover, the articles are inserted within recent critical debates on adaptation, digital media and national and transnational cinema (Naremore, Sobchack, Druckery and Williams. All articles combine important theoretical concerns with the analysis of specific films. Robert Stam's “Teoria e Prática da Adaptação: da Fidelidade à Intertextualidade” (“Theory and the practice of adaptation: from fidelity to intertextuality” offers a rich perspective on the issue of adaptation in its relationship with critical theory. He analyses the changing critical views on adaptation, which go from the priority given to the canonic literary text, as an origin, to a more fluid, intertextual and dialogical approach to film adaptation.

2010-10-01

Full Text Available In the 1990s, the film industry in China decentralized with the bankruptcy of the state-owned studio system. Privatized independent film companies took over where the government had left off and a more independent film culture emerged. Although obstacles such as political censorship, financial pressures, and Hollywood infiltration were still in the way for Chinese filmmakers, privatization of the film industry was under way. As a result of this process, new film productions of controversial subject matter came into being. In 1998 one of China’s first independent film production companies—Dream Factory—was founded. Dream Factory’s first production, in association with Berlin-based German producer Philippe Bober, was the 'Suzhou River, 'directed by its founder Lou Ye'.'1 The 2000 film, though winning prizes at international film festivals such as the Rotterdam Film Festival and the Paris Film Festival, has been banned by the Chinese government since its production.

We present a model for demagnetization in photomagnetic films, and investigate different regimes for the magnetizing process using finite element analysis. It is found that the demagnetizing factor may depend strongly upon the high-spin fraction of the film, and the specifics of the dependence are dictated by the microscopic morphology of the photomagnetic domains. This picture allows for facile interpretation of existing data on photomagnetic films, and can even explain an observed photoinduced decrease in low-field magnetization concurrent with increase in high-spin fraction. As a whole, these results reiterate the need to consider demagnetizing effects in photomagnetic films. - Highlights: Black-Right-Pointing-Pointer Finite element methods are used to examine demagnetization in photomagnetic films. Black-Right-Pointing-Pointer Under the right conditions, photomagnetic films may show a photoinduced decrease. Black-Right-Pointing-Pointer Demagnetization in photomagnets will be important to consider in possible devices.

Film Censorship Policy During Park Chung Hee’s Military Regime (1960–1979 and Hostess Films

Directory of Open Access Journals (Sweden)

Molly Hyo Kim

2018-04-01

Full Text Available Park Chung-hee’s military government (1960-1979 purportedly used film censorship to distract the public from political consciousness by controlling political materials in films while condoning censorship control on sexual content. As a result, the production of soft-core adult films soared and became popular among Korean audiences. One such film genre that thrived during this period, so-called hostess films (prostitute films, is worthy of attention for the films’ foregrounding issues of class, poverty and other social issues that the state censorship board heavily regulated. In viewing such dynamics between state censorship and film, this article aims to unravel the questions of how the state was willing to turn a blind eye to the explicit sexualization of women in hostess films when film censorship was at its peak and why the social and political aspects of this group of films about female sexual workers were not considered socially relevant by the censorship board, through scrutinizing the interplay between Park’s state censorship and hostess films. Furthermore, it offers an analysis of a hostess film, The Rose that Swallowed Thorn (Cheong, 1979, as a case study to show how it strategically orchestrates visual and thematic elements to circumvent censorship enforcement.

The molecular orientation of π-conjugated molecules has been reported to significantly affect the performance of organic photovoltaic devices (OPVs) based on molecular films. Hence, the control of molecular orientation is a key issue toward the improvement of OPV performance. In this research, oriented thin films of an n-type molecule, 3,4,9,10-Perylenetetracarboxylic Bisbenzimida-zole (PTCBI), were formed by deposition on in-plane oriented polythiophene (PT) films. Orientation of the PTCBI films was evaluated by polarized UV-vis spectroscopy and 2D-Grazing incidence X-ray diffraction. Results indicated that PTCBI molecules on PT film exhibit nearly edge-on and in-plane orientation (with molecular long axis along the substrate), whereas PTCBI molecules without PT film exhibit neither. OPVs composed of PTCBI molecular film with and without PT were fabricated and evaluated for correlation of orientation with performance. The OPVs composed of PTCBI film with PT showed higher power conversion efficiency (PCE) than that of film without PT. The experiment indicated that in-plane orientation of PTCBI molecules absorbs incident light more efficiently, leading to increase in PCE.

The object of this paper is to give a new user some practical information on the use of radiochromic films for medical applications. While various aspects of radiochromic film dosimetry for medical applications have been covered in some detail in several other excellent review articles which have appeared in the last few years [Niroomand-Rad, A., Blackwell, C.R., Coursey, B.M., Gall, K.P., McLaughlin, W.L., Meigooni, A.S., Nath, R., Rodgers, J.E., Soares, C.G., 1998.

R41, 61-120], it is the intent of the present author to present material from a more user-oriented and practical standpoint. That is, how the films work will be stressed much less than how to make the films work well. The strength of radiochromic films is most evident in applications where there is a very high dose gradient and relatively high absorbed dose rates. These conditions are associated with brachytherapy applications, measurement of small fields, and at the edges (penumbra regions) of larger fields

US/Russian Joint Film Test

A joint U.S./Russian film test was conducted during MIR Mission 18 to evaluate the effects of radiation on photographic film during long-duration space flights. Two duplicate sets of film were flown on this MIR mission: one set was processed and evaluated by the NASA/JSC Photographic Laboratory, and the other by the RKK Energia's Photographic Laboratory in Moscow. This preliminary report includes only the results of the JSC evaluation (excluding the SN-10 film which was not available for evaluation at the time this report was written). The final report will include an evaluation by JSC of the SN-10 film and an evaluation of the test data by the RKK Energia. ISC's evaluation of the test data showed the positive film flown was damaged very little when exposed to approximately 8 rads of radiation. Two of the three negative films were significantly damaged and the third film was damaged only moderately.

A high-throughput characterization technique based on digital holography for mapping film thickness in thin-film materials libraries was developed. Digital holographic microscopy is used for fully automatic measurements of the thickness of patterned films with nanometer resolution. The method has several significant advantages over conventional stylus profilometry: it is contactless and fast, substrate bending is compensated, and the experimental setup is simple. Patterned films prepared by different combinatorial thin-film approaches were characterized to investigate and demonstrate this method. The results show that this technique is valuable for the quick, reliable and high-throughput determination of the film thickness distribution in combinatorial materials research. Importantly, it can also be applied to thin films that have been structured by shadow masking.

Thin Cu film resistivity using four probe techniques: Effect of film thickness and geometrical shapes

Choudhary, Sumita; Narula, Rahul; Gangopadhyay, Subhashis

2018-05-01

Precise measurement of electrical sheet resistance and resistivity of metallic thin Cu films may play a significant role in temperature sensing by means of resistivity changes which can further act as a safety measure of various electronic devices during their operation. Four point probes resistivity measurement is a useful approach as it successfully excludes the contact resistance between the probes and film surface of the sample. Although, the resistivity of bulk samples at a particular temperature mostly depends on its materialistic property, however, it may significantly differ in the case of thin films, where the shape and thickness of the sample can significantly influence on it. Depending on the ratio of the film thickness to probe spacing, samples are usually classified in two segments such as (i) thick films or (ii) thin films. Accordingly, the geometric correction factors G can be related to the sample resistivity r, which has been calculated here for thin Cu films of thickness up to few 100 nm. In this study, various rectangular shapes of thin Cu films have been used to determine the shape induced geometric correction factors G. An expressions for G have been obtained as a function of film thickness t versus the probe spacing s. Using these expressions, the correction factors have been plotted separately for each cases as a function of (a) film thickness for fixed linear probe spacing and (b) probe distance from the edge of the film surface for particular thickness. Finally, we compare the experimental results of thin Cu films of various rectangular geometries with the theoretical reported results.

2018-01-09

Atomic-layer-deposition (ALD) of In 2 O 3 nano-films has been investigated using cyclopentadienyl indium (InCp) and hydrogen peroxide (H 2 O 2 ) as precursors. The In 2 O 3 films can be deposited preferentially at relatively low temperatures of 160-200 °C, exhibiting a stable growth rate of 1.4-1.5 Å/cycle. The surface roughness of the deposited film increases gradually with deposition temperature, which is attributed to the enhanced crystallization of the film at a higher deposition temperature. As the deposition temperature increases from 150 to 200 °C, the optical band gap (E g ) of the deposited film rises from 3.42 to 3.75 eV. In addition, with the increase of deposition temperature, the atomic ratio of In to O in the as-deposited film gradually shifts towards that in the stoichiometric In 2 O 3 , and the carbon content also reduces by degrees. For 200 °C deposition temperature, the deposited film exhibits an In:O ratio of 1:1.36 and no carbon incorporation. Further, high-performance In 2 O 3 thin-film transistors with an Al 2 O 3 gate dielectric were achieved by post-annealing in air at 300 °C for appropriate time, demonstrating a field-effect mobility of 7.8 cm 2 /V⋅s, a subthreshold swing of 0.32 V/dec, and an on/off current ratio of 10 7 . This was ascribed to passivation of oxygen vacancies in the device channel.

Underwater 3D filming

Full Text Available After an experimental phase of many years, 3D filming is now effective and successful. Improvements are still possible, but the film industry achieved memorable success on 3D movie’s box offices due to the overall quality of its products. Special environments such as space (“Gravity” and the underwater realm look perfect to be reproduced in 3D. “Filming in space” was possible in “Gravity” using special effects and computer graphic. The underwater realm is still difficult to be handled. Underwater filming in 3D was not that easy and effective as filming in 2D, since not long ago. After almost 3 years of research, a French, Austrian and Italian team realized a perfect tool to film underwater, in 3D, without any constrains. This allows filmmakers to bring the audience deep inside an environment where they most probably will never have the chance to be.

Film-thickness dependence of structure formation in ultra-thin polymer blend films

2002-01-01

We investigated the film-thickness dependence of structure formation in ultra-thin polymer blend films prepared from solution. As a model system we used binary blends of statistical poly(styrene-co-p-bromostyrene) copolymers of different degrees of bromination. Ultra-thin-film samples differing in miscibility and film thickness were prepared via spin coating of common toluene solutions onto silicon (100) substrates. The resulting morphologies were investigated with scanning force microscopy, reflectometry and grazing-incidence scattering techniques using both X-rays and neutrons in order to obtain a picture of the sample structure at and below the sample surface.

Graphical abstract: - Highlights: • PB-based ECD employed micro-patterned FTO electrode was fabricated. • Effect of interface morphology on electrochromic characteristics was examined. • Electrochromic properties were enhanced by employing a patterned interface. - Abstract: The effect of interface morphology on electrochromic characteristics was examined for an electrochromic device (ECD). Micro-patterned fluorine-doped tin oxide (FTO) films were fabricated using a photolithography process. Prussian blue (PB) films were then deposited on the patterned FTO films. The surface areas of both PB films and FTO films were increased by patterning. ECDs were assembled using patterned PB/FTO films as the electrochromic electrode, bare FTO films as the counter electrode, and an electrolyte containing LiClO 4 salt. The increased effective surface area of the patterned PB/FTO electrode boosted the mobility of ions at the interphase between the electrolyte and PB electrode, and the electron transfer between PB films and FTO films. As a result, electrochromic properties such as transmittance and response time were significantly improved by employing the patterned FTO films as the transparent conductive oxide layer of the electrochromic electrode

Wang, Lei; Liu, Chang-sheng; Shi, Lei; An, Cheng-qiang

2015-02-01

A composite silanes-V-Zr passive film was overlayed on hot-dip galvanized steel. Attenuated total reflection Fourier transformed infrared spectroscopy (ATR-FTIR), X-ray photoelectron spectrometer (XPS) and radio frequency glow discharge optical emission spectrometry (rf-GD-OES) were used to characterize the molecular structure of the silanes-V-Zr passive film. The mechanism of film formation was discussed: The results show that the silane molecules are crosslinked as the main film former and inorganic inhibitor is even distributed in the film. The fitting peak of 100.7 eV in XPS single Si2p energy range spectra of the composite silanes-V-Zr passive film and the widening and strengthening of the Si--O infrared absorption peak at 1100 cm(-1) indicate that the silanes were adsorbed on the surface of zinc with chemical bond of Si--O--Zn, and the silane molecules were connected with each other by bond of Si--O--Si. Two characteristic absorption peaks of amide at 1650 and 1560 cm(-1) appear in the infrared spectroscopy of the composite silanes-V-Zr passive film, and a characteristic absorption peak of epoxy groups at 910 cm(-1) disappears in the infrared spectroscopy of the passive film. The results indicate that gamma-APT can be prepared through nucleophilic ring-opening of ethylene oxide in gamma-GPT molecule to form C--N covalent bonds. The rf-GD-OES results indicate that there is a oxygen enriched layer in 0.3 microm depth of the composite silanes-V-Zr passive film. Moreover, ZrF4, ZrO2 and some inorganic matter obtained by the reaction during the forming processof the composite silanes-V-Zr passive film are distributed evenly throughout the film. According to the film composition, the physical processes and chemical reactions during the film forming process were studied by using ATR-FTIR. Based on this, the film forming mechanism was proposed.

Alternative sandwich panel decorative films were investigated as replacements for the polyvinyl fluoride currently used in aircraft interiors. Candidate films were studied for flammability, smoke emission, toxic gas emission, flame spread, and suitability as a printing surface for the decorative acrylic ink system. Several of the candidate films tested were flame modified polyvinyl fluoride, polyvinylidene fluoride, polyimide, polyamide, polysulfone, polyphenylsulfone, polyethersulfone, polybenzimidazole, polycarbonate, polyparabanic acid, polyphosphazene, polyetheretherketon, and polyester. The films were evaluated as pure films only, films silk-screened with an acrylic ink, and films adhered to a phenolic fiberglass substrate. Films which exhibited the highest fire resistant properties included PEEK polyetheretherketon, Aramid polyamide, and ISO-BPE polyester.

Predicting film genres with implicit ideals

Full Text Available We present a new approach to defining film genre based on implicit ideals. When viewers rate the likability of a film, they indirectly express their ideal of what a film should be. Across six studies we investigate the category structure that emerges from likability ratings and the category structure that emerges from the features of film. We further compare these data-driven category structures with human annotated film genres. We conclude that film genres are structured more around ideals than around features of film. This finding lends experimental support to the notion that film genres are set of shifting, fuzzy, and highly contextualized psychological categories.

Camillo Negro, Professor in Neurology at the University of Torino, was a pioneer of scientific film. From 1906 to 1908, with the help of his assistant Giuseppe Roasenda and in collaboration with Roberto Omegna, one of the most experienced cinematographers in Italy, he filmed some of his patients for scientific and educational purposes. During the war years, he continued his scientific film project at the Military Hospital in Torino, filming shell-shocked soldiers. In autumn 2011, the Museo Nazionale del Cinema, in partnership with the Faculty of Neurosciences of the University of Torino, presented a new critical edition of the neuropathological films directed by Negro. The Museum's collection also includes 16 mm footage probably filmed in 1930 by Doctor Fedele Negro, Camillo's son. One of these films is devoted to celebrating the effects of the so-called "Bulgarian cure" on Parkinson's disease.

Process for forming thin film, heat treatment process of thin film sheet, and heat treatment apparatus therefor

Watanabe, S.

1984-01-01

The invention provides a process for forming a magnetic thin film on a base film, a heat treatment process of a thin film sheet consisting of the base film and the magnetic thin film, and an apparatus for performing heat treatment of the thin film sheet. Tension applied to the thin film sheet is substantially equal to that applied to the base film when the magnetic thin film is formed thereon. Then, the thin film sheet is treated with heat. The thin film sheet is heated with a given temperature gradient to a reactive temperature at which heat shrinkage occurs, while the tension is being applied thereto. Thereafter, the thin film sheet to which the tension is still applied is cooled with substantially the same temperature gradient as applied in heating. The heat treatment apparatus has a film driving unit including a supply reel, a take-up reel, a drive source and guide rollers; a heating unit including heating plates, heater blocks and a temperature controller for heating the sheet to the reactive temperature; and a heat insulating unit including a thermostat and another temperature controller for maintaining the sheet at the nonreactive temperature which is slightly lower than the reactive temperature

To determine the frequency of malaria parasite detection from the buffy coat blood films by using capillary tube in falciparum malaria patients with negative conventional thick films. Thirty six uncomplicated falciparum malaria patients confirmed by conventional thick and thin films were included in the study. The patients were treated with artemisinin combination therapy at Hospital for Tropical Diseases, Bangkok, Thailand for 28 day. Fingerpricks for conventional blood films were conducted every 6 hours until negative parasitemia, then daily fingerpricks for parasite checks were conducted until the patients were discharged from hospital. Blood samples were also concurrently collected in 3 heparinized capillary tubes at the same time of fingerpricks for conventional blood films when the prior parasitemia was negative on thin films and parasitemia was lower than 50 parasites/200 white blood cells by thick film. The first negative conventional thick films were compared with buffy coat thick films for parasite identification. Out of 36 patients with thick films showing negative for asexual forms of parasites, buffy coat films could detect remaining 10 patients (27.8%) with asexual forms of Plasmodium falciparum. The study shows that buffy coat thick films are useful and can detect malarial parasites in 27.8% of patients whose conventional thick films show negative parasitemia.

Films from the Couch: Film Theory and Psychoanalysis

Directory of Open Access Journals (Sweden)

Pedro Sangro Colón

2008-10-01

Full Text Available   Different disciplines have contributed to weaving a theory of psychoanalysis in the cinema: ranging from the loans from anthropology and experimental psychology, to proposals belonging to the specific sphere of film theory, such as Filmology, Text Analysis or Feminist Theory in films. In all cases, the aim is to establish a relationship between the significance structure that governs the cinema and psychology, so as to confirm that the cinema’s system of representation is modelled on our unconscious psychological apparatus, as was explained by the psychoanalyst Jacques Lacan, among others. The arrival of psychoanalysis in film thought forges the idea that considers the cinema as an auxiliary psychological device capable of making us subjects and submerging us in the emotions in play in the conflicts proposed by any audiovisual story.

Highlights: • We present a highly efficient method for preparing WSe{sub 2} film by rapid selenization. • The W film phase composition has little effect on WSe{sub 2} film orientation. • W film density is a critical factor that influences the WSe{sub 2} orientation. • A growth model was proposed for two kinds of WSe{sub 2} film textures. - Abstract: The tungsten diselenide (WSe{sub 2}) films with different orientation present unique properties suitable for specific applications, such as WSe{sub 2} with a C-axis⊥substrate for optoelectronics and WSe{sub 2} with a C-axis // substrate for electrocatalysts. Orientation control of WSe{sub 2} is essential for realizing the practical applications. In this letter, a WSe{sub 2} film has been prepared via rapid selenization of a magnetron-sputtered tungsten (W) film. The influence of the magnetron-sputtered W film on WSe{sub 2} film growth was studied systematically. Scanning electron microscopy, X-ray diffractometry and high-resolution transmission electron microscopy were used to evaluate the morphology, microstructure and phase composition of the W and WSe{sub 2} films. The substrate temperature has a significant effect on the W film phase composition, but little effect on the WSe{sub 2} film orientation. The WSe{sub 2} orientation can be controlled by changing the W film microstructure. A dense W film that is deposited at low pressure is conducive to the formation of WSe{sub 2} with a C-axis⊥substrate, whereas a porous W film deposited at high pressure favors the formation of WSe{sub 2} with a C-axis // substrate. A growth model for the WSe{sub 2} film with different texture has been proposed based on the experimental results. The direction of selenium (Se) vapor diffusion differs at the top and side surfaces. This is a key factor for the preparation of anisotropic WSe{sub 2} films. Highly oriented WSe{sub 2} films with a C-axis⊥substrate grow from the dense W film deposited at low pressure because Se vapor

Full Text Available The objective of this study is to determine physical, mechanical and barrier properties of chitosan-laminated collagen film. Commercial collagen film, which is used for making collagen casings for dry fermented sausage production, was laminated with chitosan film layer in order to improve the collagen film barrier properties. Different volumes of oregano essential oil per 100 mL of filmogenic solution were added to chitosan film layer: 0, 0.2, 0.4, 0.6 and 0.8 mL to optimize water vapour barrier properties. Chitosan layer with 0.6 or 0.8 % of oregano essential oil lowered the water vapour transmission rate to (1.85±0.10·10–6 and (1.78±0.03·10–6 g/(m2·s·Pa respectively, compared to collagen film ((2.51±0.05·10–6 g/(m2·s·Pa. However, chitosan-laminated collagen film did not show improved mechanical properties compared to the collagen one. Tensile strength decreased from (54.0±3.8 MPa of the uncoated collagen film to (36.3±4.0 MPa when the film was laminated with 0.8 % oregano essential oil chitosan layer. Elongation at break values of laminated films did not differ from those of collagen film ((18.4±2.7 %. Oxygen barrier properties were considerably improved by lamination. Oxygen permeability of collagen film was (1806.8±628.0·10–14 cm3/(m·s·Pa and values of laminated films were below 35·10–14 cm3/(m·s·Pa. Regarding film appearance and colour, lamination with chitosan reduced lightness (L and yellowness (+b of collagen film, while film redness (+a increased. These changes were not visible to the naked eye.

[Psychopathology and film: a valuable interaction?].

Film or film fragments are often used in psychopathology education. However, so far there have been very few articles that have discussed the benefits and limitations of using films to explain or illustrate psychopathology. Although numerous films involves psychopathology in varying degrees, it is not clear how we can use films for psychopathology education. To examine the advantages, limitations and possible methods of using film as a means of increasing our knowledge and understanding of psychiatric illnesses. We discuss five examples that illustrate the interaction of film and psychopathology. On the one hand we explain how the psychopathological concepts are used in each film and on the other hand we explain which aspects of each film are valuable aids for teaching psychopathology. The use of film makes it possible to introduce the following topics in psychopathological teaching programme: holistic psychiatric reasoning, phenomenology and the subjective experience, the recognition of psychopathological prototypes and the importance of context. There is undoubtedly an analogy between the method we have chosen for teaching psychopathology with the help of films and the holistic approach of the psychiatrist and his or her team. We believe psychopathology education can benefit from films and we would recommend our colleagues to use it in this way.

Film dosimetry in conformal radiotherapy

Energy Technology Data Exchange (ETDEWEB)

Danciu, C; Proimos, B S [Patras Univ. (Greece). Dept. of Medical Physics

Dosimetry, through a film sandwiched in a transverse cross-section of a solid phantom, is a method of choice in Conformal Radiotherapy because: (a) the blackness (density) of the film at each point offers a measure of the total dose received at that point, and (b) the film is easily calibrated by exposing a film strip in the same cross-section, through a stationary field. The film must therefore have the following properties: (a) it must be slow, in order not to be overexposed, even at a therapeutic dose of 200 cGy, and (b) the response of the film (density versus dose curve) must be independent of the photon energy spectrum. A few slow films were compared. It was found that the Kodak X-Omat V for therapy verification was the best choice. To investigate whether the film response was independent of the photon energy, response curves for six depths, starting from the depth of maximum dose to the depth of 25 cm, in solid phantom were derived. The vertical beam was perpendicular to the anterior surface of the phantom, which was at the distance of 100 cm from the source and the field was 15x15 cm at that distance. This procedure was repeated for photon beams emitted by a Cobalt-60 unit, two 6 MV and 15 MV Linear Accelerators, as well as a 45 MV Betatron. For each of those four different beams the film response was the same for all six depths. The results, as shown in the diagrams, are very satisfactory. The response curve under a geometry similar to that actually applied, when the film is irradiated in a transverse cross-section of the phantom, was derived. The horizontal beam was almost parallel (angle of 85) to the plane of the film. The same was repeated with the central ray parallel to the film (angle 90) and at a distance of 1.5 cm from the horizontal film. The field size was again 15x15 at the lateral entrance surface of the beam. The response curves remained the same, as when the beam was perpendicular to the films.

Different methods of polymer grafting using gamma irradiation are reported in the present study for the preparation of newly functionalized biodegradable films, and some important properties related to their mechanical and barrier properties are described. Biodegradable films composed of zein and poly(vinyl alcohol) (PVA) were gamma-irradiated in presence of different ratios of acrylic acid (AAc) monomer for compatibilization purpose. Resulting grafted films (zein/PVA-g-AAc) had their puncture strength (PS=37–40 N mm −1 ) and puncture deformation (PD=6.5–9.8 mm) improved for 30% and 50% PVA in blend, with 5% AAc under 20 kGy. Methylcellulose (MC)-based films were irradiated in the presence of 2-hydroxyethyl methacrylate (HEMA) or silane, in order to determine the effect of monomer grafting on the mechanical properties of films. It was found that grafted films (MC-g-HEMA and MC-g-silane) using 35% monomer performed higher mechanical properties with PS values of 282–296 N mm −1 and PD of 5.0–5.5 mm under 10 kGy. Compatibilized polycaprolactone (PCL)/chitosan composites were developed via grafting silane in chitosan films. Resulting trilayer grafted composite film (PCL/chitosan-g-silane/PCL) presented superior tensile strength (TS=22 MPa) via possible improvement of interfacial adhesion (PCL/chitosan) when using 25% silane under 10 kGy. Finally, MC-based films containing crystalline nanocellulose (CNC) as a filling agent were prepared and irradiated in presence of trimethylolpropane trimethacrylate (TMPTMA) as a grafted plasticizer. Grafted films (MC-g-TMPTMA) presented superior mechanical properties with a TS of 47.9 MPa and a tensile modulus (TM) of 1792 MPa, possibly due to high yield formation of radicals to promote TMPTMA grafting during irradiation. The addition of CNC led to an additional improvement of the barrier properties, with a significant 25% reduction of water vapor permeability (WVP) of grafted films. - Highlights: • Irradiation of zein

Engineering Graphene Films from Coal

Science.gov (United States)

Vijapur, Santosh H.

Graphene is a unique material with remarkable properties suitable for a wide array of applications. Chemical vapor deposition (CVD) is a simple technique for synthesis of large area and high quality graphene films on various metal substrates. Among the metal substrates, copper has been shown to be an excellent support for the growth of graphene films. Traditionally, hydrocarbon gases are used for the graphene synthesis via CVD. Unconventional solid carbon sources such as various polymers and food waste have also shown great potential for synthesis of graphene films. Coal is one such carbon enriched and abundantly available unconventional source. Utilization of coal as a carbon source to synthesize large area, transparent, and high quality few-layer graphene films via CVD has been demonstrated in the present work. Hydrocarbon gases are released as products of coal pyrolysis at temperatures ≥400 °C. This study hypothesized that, these hydrocarbon gases act as precursors for the synthesis of graphene films on the copper substrate. Hence, atmospheric pressure CVD and low temperature of 400 °C were utilized initially for the production of graphene films. These conditions were suitable for the formation of amorphous carbon (a-C) films but not crystalline graphene films that were the objective of this work. The synthesized a-C films on the copper substrate were shown to be uniform and transparent with large surface area. The thickness and surface roughness of the a-C films were determined to have typical values of 5 nm and 0.55 nm, respectively. The a-C film has >95 % optical transmittance and sheet resistivity of 0.6 MO sq-1. These values are comparable to other carbon thin films synthesized at higher temperatures. Further, the a-C films were transferred onto any type of substrate such as silicon wafer and titanium foil, and can be utilized for diverse applications. However, crystalline graphene films were not produced by implementing atmospheric pressure CVD and low

Graphical abstract: - Highlights: • PB-based ECD employed micro-patterned FTO electrode was fabricated. • Effect of interface morphology on electrochromic characteristics was examined. • Electrochromic properties were enhanced by employing a patterned interface. - Abstract: The effect of interface morphology on electrochromic characteristics was examined for an electrochromic device (ECD). Micro-patterned fluorine-doped tin oxide (FTO) films were fabricated using a photolithography process. Prussian blue (PB) films were then deposited on the patterned FTO films. The surface areas of both PB films and FTO films were increased by patterning. ECDs were assembled using patterned PB/FTO films as the electrochromic electrode, bare FTO films as the counter electrode, and an electrolyte containing LiClO{sub 4} salt. The increased effective surface area of the patterned PB/FTO electrode boosted the mobility of ions at the interphase between the electrolyte and PB electrode, and the electron transfer between PB films and FTO films. As a result, electrochromic properties such as transmittance and response time were significantly improved by employing the patterned FTO films as the transparent conductive oxide layer of the electrochromic electrode.

One Film, or Many?: The Multiple Texts of the Colonial Korean Film "Volunteer"

Directory of Open Access Journals (Sweden)

Jaekil Seo

2012-12-01

Full Text Available Until recently, studies on films from colonial Korea in the Japanese empire had to rely primarily on secondary texts, such as memoirs, journal and newspaper articles, and film reviews. The recent discovery of original film texts from archives in Japan, China, Russia, and elsewhere and their availability on DVD format, prompted an important turning point in the scholarship. However, juxtaposing these newly released DVD versions with other archival sources exposes significant differences among the existing versions of texts. For instance, a newly discovered script reveals that important segments are missing in the recently released DVD version of the propaganda film "Volunteer." There also exist important discrepancies in the dialogue among the original film script, the actual film version, the synopsis, and the Japanese subtitles. Some of the Korean-language dialogue, which might be interpreted as exhibiting some ambivalence toward Japanese imperial policies, was completely silenced through strategic omissions in the Japanese-language subtitles targeting Japanese audiences. Some Japanese-language translations of the script also exhibit drastic changes from the original Korean-language dialogue. Piecing together such fragmented and fraught linguistic dissonance found in the colonial archives, we can conjecture that viewers from the colony and the metropole of "Volunteer" may have consumed very different versions of the film. This article aims to examine the significance of such dissonance, which has only recently become audible in so-called films of transcolonial coproduction.

Plasma-polymerized SiOx deposition on polymer film surfaces for preparation of oxygen gas barrier polymeric films

International Nuclear Information System (INIS)

Inagaki, N.

2003-01-01

SiOx films were deposited on surfaces of three polymeric films, PET, PP, and Nylon; and their oxygen gas barrier properties were evaluated. To mitigate discrepancies between the deposited SiOx and polymer film, surface modification of polymer films was done, and how the surface modification could contribute to was discussed from the viewpoint of apparent activation energy for the permeation process. The SiOx deposition on the polymer film surfaces led to a large decrease in the oxygen permeation rate. Modification of polymer film surfaces by mans of the TMOS or Si-COOH coupling treatment in prior to the SiOx deposition was effective in decreasing the oxygen permeation rate. The cavity model is proposed as an oxygen permeation process through the SiOx-deposited Nylon film. From the proposed model, controlling the interface between the deposited SiOx film and the polymer film is emphasized to be a key factor to prepare SiOx-deposited polymer films with good oxygen gas barrier properties.

Recently, graphene films have always attracted attention due to their excellent characteristics in energy storage. In this work, a novel graphene oxide (GO) film with excellent mechanical properties, whose thickness was regulated simply via changing the concentration of the surfactant, was successfully prepared by foam film method. After chemical reduction, the reduced GO (rGO) films have excellent electrical conductivity of ∼172 S cm-1. Moreover, the supercapacitors based on the rGO films exhibit satisfied capacitive performance of ∼56 mF cm-2 at 0.2 mA cm-2 in 6 M KOH aqueous solution. Meanwhile, the flexible all solid state supercapacitors (FSSCs) based on the rGO films also show great volumetric capacitance of ∼2810 mF cm-3 at 12 mA cm-3 (∼1607 mF cm-3 at 613 mA cm-3) with polyvinyl alcohol-KOH gel electrolyte. Besides, after 10000 cycles and continuously bent to 180° for 300 times, the volumetric capacitance of the FSSC remains at 81.4% and 90.4% of its initial capacitance value, respectively. Therefore, the free-standing rGO films prepared via foam film method could be considered as promising electrode materials for high performance flexible supercapacitors.

The purpose of this study was to test the association between tear film fluorescence changes during tear break-up (TBU) or thinning and the concurrent ocular sensory response. Sixteen subjects kept one eye open as long as possible (MBI), indicated their discomfort level continuously, and rated ocular sensations of irritation, stinging, burning, pricking, and cooling using visual analog scales (VAS). Fluorescence of the tear film was quantified by a pixel-based analysis of the median pixel intensity (PI), TBU, and percentage of dark pixels (DarkPix) over time. A cutoff of 5% TBU was used to divide subjects into either break-up (BU) or minimal break-up (BUmin) groups. Tear film fluorescence decreased (median PI) and the percentage of TBU and DarkPix increased in all trials, with the rate significantly greater in the BU than the BUmin group (Mann-Whitney U test, P film thinning best explains decreasing tear film fluorescence during trials. This was highly correlated with increasing ocular discomfort, suggesting that both tear film thinning and TBU stimulate underlying corneal nerves, although TBU produced more rapid stimulation. Slow increases in tear film hyperosmolarity may cause the gradual increase in discomfort during slow tear film thinning, whereas the sharp increases in discomfort during TBU suggest a more complex stimulus.

Fiction Film Dialogue vs Documentary Film Dialogue: Genre Peculiarities of Translation

Directory of Open Access Journals (Sweden)

Вера Евгеньевна Горшкова

2016-12-01

Full Text Available The article gives an analysis of the film dialogue translation depending on the genre peculiarities of a spoken word medium, i. e. of a fiction film and of a documentary. The latter is traditionally disregarded by linguists and translators due to an established opinion that it lacks an overt literary aesthetic component. Thus it makes a documentary much easier to translate and its text gets closer to the information text the translation dominant of which is to render its information component. The article analyses an universal character of image-sense applied to different cinematographic genres. This thesis is demonstrated with examples from fiction and documentary film dialogues such as The Artist, Il y a longtemps que je t’aime, Espionne pendant la seconde guerre mondiale translated into French and Russian. It is highlighted that particular verbal components/utterances quite often get especially crucial in the context of the film dialogue increasing its poetic function and creating a complete image-sense. Such lexical units as personal pronouns «ты» and «вы» (you as the 2nd person singular in Russian and the 2nd person plural, respectively have no small share in the above process as their adequate translation contributes to the audience's integral perception of the film as an aesthetic phenomenon. It is postulated that a documentary that deals with «the creative elaboration of the reality» has a lot in common with a fiction film in the regard of its compliance with the director's intention, the presentation of the sequence of events and their respective interpretation in the film. In this regard the adequate rendering of the image-sense of a documentary is especially vital in the analysis of events separated in time. That supposition can be backed up by a translation project carried out on the material of the film dialogue translation of the documentary «Espionne pendant la seconde guerre mondiale» from French into Russian.

Soap Films as 1D waveguides

Directory of Open Access Journals (Sweden)

Emile Olivier

2014-01-01

Full Text Available Laser light is injected in a free standing horizontal draining soap film through the glass frame sustaining the film. Two propagation regimes are clearly identified depending on the film thickness. At the beginning of the drainage, the soap film behaves as a multimode-one dimensional optofiuidic waveguide. In particular, we observe that the injected light creates a bottleneck in the film and part of the injected light is refracted leading to whiskers. At the end of the drainage where the film thickness is below 1μm, there is a strong selection among the various possible optical modes in the film, and part of the light is defiected. This leads to a self selection of the mode propagation inside the film.

Thermogravimetric analysis of fuel film evaporation

Institute of Scientific and Technical Information of China (English)

HU Zongjie; LI Liguang; YU Shui

2006-01-01

Thermogravimetric analysis (TGA) was compared with the petrochemical distillation measurement method to better understand the characteristics of fuel film evaporation at different wall tem- peratures. The film evaporation characteristics of 90# gasoline, 93# gasoline and 0# diesel with different initial thicknesses were investigated at different environmental fluxes and heating rates. The influences of heating rate, film thickness and environmental flux on fuel film evaporation for these fuels were found. The results showed that the environmental conditions in TGA were similar to those for fuel films in the internal combustion engines, so data from TGA were suitable for the analysis of fuel film evaporation. TGA could simulate the key influencing factors for fuel film evaporation and could investigate the basic quantificational effect of heating rate and film thickness. To get a rapid and sufficient fuel film evaporation, sufficiently high wall temperature is necessary. Evaporation time decreases at a high heating rate and thin film thickness, and intense gas flow is important to promoting fuel film evaporation. Data from TGA at a heating rate of 100℃/min are fit to analyze the diesel film evaporation during cold-start and warming-up. Due to the tense molecular interactions, the evaporation sequence could not be strictly divided according to the boiling points of each component for multicomponent dissolved mixture during the quick evaporation process, and the heavier components could vaporize before reaching their boiling points. The 0# diesel film would fully evaporate when the wall temperature is beyond 250℃.

Full Text Available The history of African film began in the 1960s with the independence of the colonies. Despite all kinds of political and economic difficulties, numerous films have been made since then, featuring wide-ranging processes of consolidation, differentiation and transformation which were characteristic of post-colonial sub-Saharan Africa. However, these feature films should not merely be viewed as back references to specifically African problems. The glimmering fictions are imagination spaces. They preserve ideas about how the post-colonial circumstances should be approached. Seen from this perspective, the history of African film may be studied as a history of African utopias. Die Geschichte des afrikanischen Films begann mit der Unabhängigkeit in den 1960er Jahren. Seitdem sind trotz aller politischen und ökonomischen Probleme zahlreiche Filme entstanden. Sie geben umfassende Konsolidierungs-, Differenzierungs- und Transformationsprozesse wieder, die für das postkoloniale subsaharische Afrika charakteristisch waren. Die Spielfilme sollten allerdings nicht nur als Rückschau auf spezifische Probleme Afrikas interpretiert werden. Diese flimmernden Phantasien stellen Imaginationsräume dar; in ihnen sind Ideen enthalten, wie den Bedingungen der postkolonialen Gesellschaften begegnet werden könnte. Aus dieser Sicht heraus könnte die Geschichte des afrikanischen Films auch als Geschichte afrikanischer Utopien erforscht werden.

Dosimetric characterization of GafChromic EBT film and its implication on film dosimetry quality assurance

International Nuclear Information System (INIS)

Fuss, Martina; Sturtewagen, Eva; Wagter, Carlos De; Georg, Dietmar

2007-01-01

The suitability of radiochromic EBT film was studied for high-precision clinical quality assurance (QA) by identifying the dose response for a wide range of irradiation parameters typically modified in highly-conformal treatment techniques. In addition, uncertainties associated with varying irradiation conditions were determined. EBT can be used for dose assessment of absorbed dose levels as well as relative dosimetry when compared to absolute absorbed dose calibrated using ionization chamber results. For comparison, a silver halide film (Kodak EDR-2) representing the current standard in film dosimetry was included. As an initial step a measurement protocol yielding accurate and precise results was established for a flatbed transparency scanner (Epson Expression 1680 Pro) that was utilized as a film reading instrument. The light transmission measured by the scanner was found to depend on the position of the film on the scanner plate. For three film pieces irradiated with doses of 0 Gy, ∼1 Gy and ∼7 Gy, the pixel values measured in portrait or landscape mode differed by 4.7%, 6.2% and 10.0%, respectively. A study of 200 film pieces revealed an excellent sheet-to-sheet uniformity. On a long time scale, the optical development of irradiated EBT film consisted of a slow but steady increase of absorbance which was not observed to cease during 4 months. Sensitometric curves of EBT films obtained under reference conditions (SSD = 95 cm, FS = 5 x 5 cm 2 , d = 5 cm) for 6, 10 and 25 MV photon beams did not show any energy dependence. The average separation between all curves was only 0.7%. The variation of the depth d (range 2-25 cm) in the phantom did not affect the dose response of EBT film. Also the influence of the radiation field size (range 3 x 3-40 x 40 cm 2 ) on the sensitometric curve was not significant. For EDR-2 films maximum differences between the calibration curves reached 7-8% for X6MV and X25MV. Radiochromic EBT film, in combination with a flatbed

Morphological Influence of Solution-Processed Zinc Oxide Films on Electrical Characteristics of Thin-Film Transistors

2016-10-01

Full Text Available We report on the morphological influence of solution-processed zinc oxide (ZnO semiconductor films on the electrical characteristics of ZnO thin-film transistors (TFTs. Different film morphologies were produced by controlling the spin-coating condition of a precursor solution, and the ZnO films were analyzed using atomic force microscopy, X-ray diffraction, X-ray photoemission spectroscopy, and Hall measurement. It is shown that ZnO TFTs have a superior performance in terms of the threshold voltage and field-effect mobility, when ZnO crystallites are more densely packed in the film. This is attributed to lower electrical resistivity and higher Hall mobility in a densely packed ZnO film. In the results of consecutive TFT operations, a positive shift in the threshold voltage occurred irrespective of the film morphology, but the morphological influence on the variation in the field-effect mobility was evident. The field-effect mobility in TFTs having a densely packed ZnO film increased continuously during consecutive TFT operations, which is in contrast to the mobility decrease observed in the less packed case. An analysis of the field-effect conductivities ascribes these results to the difference in energetic traps, which originate from structural defects in the ZnO films. Consequently, the morphological influence of solution-processed ZnO films on the TFT performance can be understood through the packing property of ZnO crystallites.

Direct-current substrate bias effects on amorphous silicon sputter-deposited films for thin film transistor fabrication

International Nuclear Information System (INIS)

Jun, Seung-Ik; Rack, Philip D.; McKnight, Timothy E.; Melechko, Anatoli V.; Simpson, Michael L.

2005-01-01

The effect that direct current (dc) substrate bias has on radio frequency-sputter-deposited amorphous silicon (a-Si) films has been investigated. The substrate bias produces a denser a-Si film with fewer defects compared to unbiased films. The reduced number of defects results in a higher resistivity because defect-mediated conduction paths are reduced. Thin film transistors (TFTs) that were completely sputter deposited were fabricated and characterized. The TFT with the biased a-Si film showed lower leakage (off-state) current, higher on/off current ratio, and higher transconductance (field effect mobility) than the TFT with the unbiased a-Si film

Magnetic anisotropies in SmCo thin films

1993-01-01

A systemic study of the deposition processes and magnetic properties for the Sm-Co film system has been carried out. Films of Sm-Co system with various magnetic anisotropies have been synthesized through sputter deposition in both crystalline and amorphous phases. The origins of various anisotropies have been studied. Thermalized sputter deposition process control was used to synthesize Fe enriched Sm-Co films with rhombohedral Th 2 Zn 17 type structure. The film exhibited unusually strong textures with the crystallographic c axes of the crystallites aligned in the film plane. A large anisotropy was resulted with easy axis in the film plane. A well defined and large in-the-film-plane anisotropy of exceptionally high value of 3.3 x 10 6 erg/cm 3 has been obtained in the amorphous SmCo films by applying a magnetic field in the film plane during deposition. It was found that the in-the-film-plane anisotropy depended essentially on the applied field and Sm concentration. For films not synthesized through thermallized sputtering, the easy axis of the film could reoriented. A perpendicular anisotropy was also presented in the film synthesized through thermallized sputtering deposition. A large in-plane anisotropy was obtained in films deposited above ambient temperatures. It was concluded that the surface induced short range ordering was the origin of the in-the-film-phase anisotropy observed in amorphous film deposited in the presence of a magnetic field. The formation mechanism was different from that of the short range ordering induced by field annealing. The perpendicular anisotropy was shown to be growth induced. Large in-plane anisotropy in amorphous films was resulted form partial crystallization in the film. Both the formation of growth induced structure and partial crystallization in the film prevented the formation of the pair ordering and decreased in-the-film-plane anisotropy

Eco-efficiency is achieved when goods and services satisfy human needs, increase the quality of life, at prices which are competitive and when environmental impacts and resource intensity are decreased to a degree that they are in accordance with the expected capacities of the Earth. Eco-efficiency is a management approach that allows enterprises to carry out environmental protection measures from a market-oriented point of view. Eco-efficiency shows that ecology and economy do not contradict each other. On the contrary, in combination, they present a gain for enterprises. The motto is: To produce more with less. The WBCSD and its member enterprises have agreed to make economic growth and sustainable development the guideline for their economic entrepreneurial actions. The WBCSD supports the close co-operation of the economy, government and other organizations, as it is only together that we can help sustainable development to achieve a breakthrough. (orig.)

2014-01-01

Different methods of polymer grafting using gamma irradiation are reported in the present study for the preparation of newly functionalized biodegradable films, and some important properties related to their mechanical and barrier properties are described. Biodegradable films composed of zein and poly(vinyl alcohol) (PVA) were gamma-irradiated in presence of different ratios of acrylic acid (AAc) monomer for compatibilization purpose. Resulting grafted films (zein/PVA-g-AAc) had their puncture strength (PS=37-40 N mm-1) and puncture deformation (PD=6.5-9.8 mm) improved for 30% and 50% PVA in blend, with 5% AAc under 20 kGy. Methylcellulose (MC)-based films were irradiated in the presence of 2-hydroxyethyl methacrylate (HEMA) or silane, in order to determine the effect of monomer grafting on the mechanical properties of films. It was found that grafted films (MC-g-HEMA and MC-g-silane) using 35% monomer performed higher mechanical properties with PS values of 282-296 N mm-1 and PD of 5.0-5.5 mm under 10 kGy. Compatibilized polycaprolactone (PCL)/chitosan composites were developed via grafting silane in chitosan films. Resulting trilayer grafted composite film (PCL/chitosan-g-silane/PCL) presented superior tensile strength (TS=22 MPa) via possible improvement of interfacial adhesion (PCL/chitosan) when using 25% silane under 10 kGy. Finally, MC-based films containing crystalline nanocellulose (CNC) as a filling agent were prepared and irradiated in presence of trimethylolpropane trimethacrylate (TMPTMA) as a grafted plasticizer. Grafted films (MC-g-TMPTMA) presented superior mechanical properties with a TS of 47.9 MPa and a tensile modulus (TM) of 1792 MPa, possibly due to high yield formation of radicals to promote TMPTMA grafting during irradiation. The addition of CNC led to an additional improvement of the barrier properties, with a significant 25% reduction of water vapor permeability (WVP) of grafted films.

In Thai, an isolate language without grammatical gender, the gender-specification can be observed in the use of first person singular pronominal reference. The selection of gender-related self-reference depends not only on sex but also on gender identity of the speaker. In this article, the complex system of pronominal reference in Thai language will be briefly introduced. After that, forms of self-reference used in the Thai film Iron Ladies are analyzed to show how the gender identity of speakers can influence their selection of pronominal reference.

Ion beam-based characterization of multicomponent oxide thin films and thin film layered structures

Fabrication of thin film layered structures of multi-component materials such as high temperature superconductors, ferroelectric and electro-optic materials, and alloy semiconductors, and the development of hybrid materials requires understanding of film growth and interface properties. For High Temperature Superconductors, the superconducting coherence length is extremely short (5--15 Angstrom), and fabrication of reliable devices will require control of film properties at extremely sharp interfaces; it will be necessary to verify the integrity of thin layers and layered structure devices over thicknesses comparable to the atomic layer spacing. Analytical techniques which probe the first 1--2 atomic layers are therefore necessary for in-situ characterization of relevant thin film growth processes. However, most surface-analytical techniques are sensitive to a region within 10--40 Angstrom of the surface and are physically incompatible with thin film deposition and are typically restricted to ultra high vacuum conditions. A review of ion beam-based analytical methods for the characterization of thin film and multi-layered thin film structures incorporating layers of multicomponent oxides is presented. Particular attention will be paid to the use of time-of-flight techniques based on the use of 1- 15 key ion beams which show potential for use as nondestructive, real-time, in-situ surface diagnostics for the growth of multicomponent metal and metal oxide thin films

Surface Modification of Solution-Processed ZrO2 Films through Double Coating for Pentacene Thin-Film Transistors

2018-03-01

We report the modification of surface properties of solution-processed zirconium oxide (ZrO2) dielectric films achieved by using double-coating process. It is proven that the surface properties of the ZrO2 film are modified through the double-coating process; the surface roughness decreases and the surface energy increases. The present surface modification of the ZrO2 film contributes to an increase in grain size of the pentacene film, thereby increasing the field-effect mobility and decreasing the threshold voltage of the pentacene thin-film transistors (TFTs) having the ZrO2 gate dielectric. Herein, the molecular orientation of pentacene film is also studied based on the results of contact angle and X-ray diffraction measurements. Pentacene molecules on the double-coated ZrO2 film are found to be more tilted than those on the single-coated ZrO2 film, which is attributed to the surface modification of the ZrO2 film. However, no significant differences are observed in insulating properties between the single-and the double-coated ZrO2 dielectric films. Consequently, the characteristic improvements of the pentacene TFTs with the double-coated ZrO2 gate dielectric film can be understood through the increase in pentacene grain size and the reduction in grain boundary density.

This project is developing inorganic thin films as membranes for gas separation applications, and as discriminating coatings for liquid-phase chemical sensors. Our goal is to synthesize these coatings with tailored porosity and surface chemistry on porous substrates and on acoustic and optical sensors. Molecular sieve films offer the possibility of performing separations involving hydrogen, air, and natural gas constituents at elevated temperatures with very high separation factors. We are focusing on improving permeability and molecular sieve properties of crystalline zeolitic membranes made by hydrothermally reacting layered multicomponent sol-gel films deposited on mesoporous substrates. We also used acoustic plate mode (APM) oscillator and surface plasmon resonance (SPR) sensor elements as substrates for sol-gel films, and have both used these modified sensors to determine physical properties of the films and have determined the sensitivity and selectivity of these sensors to aqueous chemical species.

A scientific understanding of interaction of product, film coat, film coating process, and equipment is important to enable design and operation of industrial scale pharmaceutical film coating processes that are robust and provide the level of control required to consistently deliver quality film coated product. Thermodynamic film coating conditions provided in the tablet film coating process impact film coat formation and subsequent product quality. A thermodynamic film coating model was used to evaluate film coating process performance over a wide range of film coating equipment from pilot to industrial scale (2.5-400 kg). An approximate process-imposed transition boundary, from operating in a dry to a wet environment, was derived, for relative humidity and exhaust temperature, and used to understand the impact of the film coating process on product formulation and process control requirements. This approximate transition boundary may aid in an enhanced understanding of risk to product quality, application of modern Quality by Design (QbD) based product development, technology transfer and scale-up, and support the science-based justification of critical process parameters (CPPs).

Full Text Available Almost general poly(vinyl alcohol (PVA films were prepared by the processing of a PVA solution. For the first time, a novel poly(vinyl alcohol (PVA film was prepared by the saponification of a poly(vinyl acetate (PVAc film in a heterogenous medium. Under the same saponification conditions, the influence of saponification time on the degree of saponification (DS was studied for the preparation of the saponified PVA film, and it was found that the DS varied with time. Optical microscopy was used to confirm the characteristics and surface morphology of the saponified PVA film, revealing unusual black globules in the film structure. The contact angle of the films was measured to study the surface properties, and the results showed that the saponified PVA film had a higher contact angle than the general PVA film. To confirm the transformation of the PVAc film to the PVA film, 1H nuclear magnetic resonance spectroscopy, X-ray diffraction measurements, differential scanning calorimetry, and Fourier-transform infrared spectroscopy were employed.

Radiochromic film and polarization effects

2004-01-01

Full text: A new high sensitivity radiochromic film has been tested for its polarization properties. Gafchromic HS film has been shown to produce a relatively small (less than 3%) variation in measured optical density measured at 660nm wavelength when the light source is fully linear polarized and the film is rotated through 360 deg angle. Similar variations are seen when the detector is linearly polarized. If both light source and detector is linearly polarised variations in measured optical density can reach 15% when the film is rotated through 360 deg angle. This seems to be due to a phase shift in polarised light caused by the radiochromic film resulting in the polarised light source becoming out of phase with the polarised detector. Gafchromic HS radiochromic film produces a minimal polarization response with varying angle of rotation however we recommend that a polarization test be performed on a densitometry system to establish the extent of its polarization properties before accuracy dosimetry is performed with radiochromic HS film.

Abstract This thesis analyzes how four popular combat films produced by Hollywood portray and interprets important events in American history. The films exemplify how American cinema has varied in its portrayal of the American army in relation to both the perspectives of the film makers and widely held attitudes toward war and American foreign policy. In regard to social attitudes, militarism has been an instrument to create support for war. The term describes a process where a societ...

Tsay, Chien-Yie; Huang, Tzu-Teng

2013-01-01

Indium gallium zinc oxide (IGZO) transparent semiconductor thin films were prepared by KrF excimer laser annealing of sol–gel derived precursor films. Each as-coated film was dried at 150 °C in air and then annealed using excimer laser irradiation. The influence of laser irradiation energy density on surface conditions, optical transmittances, and electrical properties of laser annealed IGZO thin films were investigated, and the physical properties of the excimer laser annealed (ELA) and the thermally annealed (TA) thin films were compared. Experimental results showed that two kinds of surface morphology resulted from excimer laser annealing. Irradiation with a lower energy density (≤250 mJ cm −2 ) produced wavy and irregular surfaces, while irradiation with a higher energy density (≥350 mJ cm −2 ) produced flat and dense surfaces consisting of uniform nano-sized amorphous particles. The explanation for the differences in surface features and film quality is that using laser irradiation energy to form IGZO thin films improves the film density and removes organic constituents. The dried IGZO sol–gel films irradiated with a laser energy density of 350 mJ/cm 2 had the best physical properties of all the ELA IGZO thin films. The mean resistivity of the ELA 350 thin films (4.48 × 10 3 Ω cm) was lower than that of TA thin films (1.39 × 10 4 Ω cm), and the average optical transmittance in the visible range (90.2%) of the ELA 350 thin films was slightly higher than that of TA thin films (89.7%). - Highlights: • IGZO semiconductor films were prepared by laser annealing of sol–gel derived films. • Surface roughness and resistivity of ELA samples were affected by energy density. • The ELA 350 IGZO film exhibited the best properties among all of ELA IGZO films. • Transmittance and resistivity of ELA 350 films are greater than those of TA films

Chemical Annealing of Zinc Tetraphenylporphyrin Films: Effects on Film Morphology and Organic Photovoltaic Performance

KAUST Repository

Trinh, Cong

2012-07-10

We present a chemical annealing process for organic thin films. In this process, a thin film of a molecular material, such as zinc tetraphenylporphyrin (ZnTPP), is exposed to a vapor of nitrogen-based ligand (e.g., pyrazine, pz, and triazine, tz), forming a film composed of the metal-ligand complex. Fast and quantitative formation of the complex leads to marked changes in the morphology and optical properties of the film. X-ray diffraction studies show that the chemical annealing process converts amorphous ZnTPP films to crystalline ZnTPP•ligand films, whose porphryin planes lie nearly parallel to the substrate (average deviation is 8° for the ZnTPP•pz film). Organic solar cells were prepared with ZnTPP donor and C 60 acceptor layers. Devices were prepared with and without chemical annealing of the ZnTPP layer with a pyrazine ligand. The devices with chemically annealed ZnTPP donor layer show an increase in short-circuit current (J SC) and fill factor (FF) relative to analogous unannealed devices, presumably because of enhanced exciton diffusion length and improved charge conductivity. The open circuit voltages (V OC) of the chemically annealed devices are lower than their unannealed counterpart because of enhanced polaron pair recombination at the donor/acceptor heterojunction. A net improvement of 5-20% in efficiency has been achieved, after chemical annealing of ZnTPP films with pyrazine. © 2012 American Chemical Society.

Realistic absorption coefficient of ultrathin films

Cesaria, M.; Caricato, A. P.; Martino, M.

2012-10-01

Both a theoretical algorithm and an experimental procedure are discussed of a new route to determine the absorption/scattering properties of thin films deposited on transparent substrates. Notably, the non-measurable contribution of the film-substrate interface is inherently accounted for. While the experimental procedure exploits only measurable spectra combined according to a very simple algorithm, the theoretical derivation does not require numerical handling of the acquired spectra or any assumption on the film homogeneity and substrate thickness. The film absorption response is estimated by subtracting the measured absorption spectrum of the bare substrate from that of the film on the substrate structure but in a non-straightforward way. In fact, an assumption about the absorption profile of the overall structure is introduced and a corrective factor accounting for the relative film-to-substrate thickness. The method is tested on films of a well known material (ITO) as a function of the film structural quality and influence of the film-substrate interface, both deliberately changed by thickness tuning and doping. Results are found fully consistent with information obtained by standard optical analysis and band gap values reported in the literature. Additionally, comparison with a conventional method demonstrates that our route is generally more accurate even if particularly suited for very thin films.

Flexible Ultra Moisture Barrier Film for Thin-Film Photovoltaic Applications

Energy Technology Data Exchange (ETDEWEB)

David M. Dean

2012-10-30

Flexible Thin-film photovoltaic (TFPV) is a low cost alternative to incumbent c-Si PV products as it requires less volume of costly semiconductor materials and it can potentially reduce installation cost. Among the TFPV options, copper indium gallium diselenide (CIGS) has the highest efficiency and is believed to be one of the most attractive candidates to achieve PV cost reduction. However, CIGS cells are very moisture sensitive and require module water vapor transmission rate (WVTR) of less than 1x10-4 gram of water per square meter per day (g-H2O/m2/day). Successful development and commercialization of flexible transparent ultra moisture barrier film is the key to enable flexible CIGS TFPV products, and thus enable ultimate PV cost reduction. At DuPont, we have demonstrated at lab scale that we can successfully make polymer-based flexible transparent ultra moisture barrier film by depositing alumina on polymer films using atomic layer deposition (ALD) technology. The layer by layer ALD approach results in uniform and amorphous structure which effectively reduces pinhole density of the inorganic coating on the polymer, and thus allow the fabrication of flexible barrier film with WVTR of 10-5 g-H2O/m2/day. Currently ALD is a time-consuming process suitable only for high-value, relatively small substrates. To successfully commercialize the ALD-on-plastic technology for the PV industry, there is the need to scale up this technology and improve throughput. The goal of this contract work was to build a prototype demonstrating that the ALD technology could be scaled-up for commercial use. Unfortunately, the prototype failed to produce an ultra-barrier film by the close of the project.

The author describes the retrospective data acquisition and evaluation on the characterization and prognosis for 776 patients (average age 40:1 years) with differentiated thyroid carcinomas in the Klinik und Poliklinik fuer Nuklearmedizin der Universitaet zu Koeln in the period from 1990 to 2005. The methodology includes patient-relevant data, examination data, imaging techniques and biochemical tests. Clinically important differences were found for papillary and follicular thyroid carcinoma. Further differences concern the localization of metastases. The author discusses the prognostic significance of the primary tumor radius in comparison with the so-called TNM classification for papillary and follicular thyroid carcinomas. It is concluded that the new version of the TNM classification offers only slight advantages with respect to the former version. It was also shown that the primary tumor size is adequate for prognostic estimations.

In this paper we demonstrate p-type thin film transistors fabricated with lead sulfide (PbS) as semiconductor deposited by chemical bath deposition methods. Crystallinity and morphology of the resulting PbS films were characterized using X-ray diffraction, atomic force microscopy and scanning electron microscopy. Devices were fabricated using photolithographic processes in a bottom gate configuration with Au as source and drain top contacts. Field effect mobility for as-fabricated devices was {approx} 0.09 cm{sup 2} V{sup -1} s{sup -1} whereas the mobility for devices annealed at 150 Degree-Sign C/h in forming gas increased up to {approx} 0.14 cm{sup 2} V{sup -1} s{sup -1}. Besides the thermal annealing, the entire fabrications process was maintained below 100 Degree-Sign C. The electrical performance of the PbS-thin film transistors was studied before and after the 150 Degree-Sign C anneal as well as a function of the PbS active layer thicknesses. - Highlights: Black-Right-Pointing-Pointer Thin film transistors with PbS as semiconductor deposited by chemical bath deposition.

2016-04-01

Full Text Available Aktuelle Diskussionen zum studienbegleitenden Deutschunterricht verdeutlichen die Notwendigkeit danach, sich bei curricularen Überlegungen sowohl an institutionellen Rahmenbedingungen als auch an spezifischen Bedürfnissen der Studierenden zu orientieren. Da Lehrwerke den damit einhergehenden Anforderungen nach Offenheit und Adaptierbarkeit nicht gerecht werden können, sind mittelfristig alternative Konzepte gefragt, die es ermöglichen, im Zuge curricularer Überlegungen die notwendige Kohärenz zwischen einzelnen Unterrichtseinheiten herzustellen und dennoch eine flexible Anpassung an konkrete Lernkontexte zu erlauben. Der vorliegende Beitrag stellt ein solches Konzept vor. Ausgehend von der Arbeit am Tatort werden drei Lernbereiche vorgestellt, die neben der Arbeit am Film auch die Arbeit an angrenzenden Themen und Texten sowie darauf aufbauend die Entwicklung studienbegleitender kommunikativer Handlungskompetenz vorsehen.  Current discussions on teaching German alongside the core subjects at university show the necessity to consider both institutional requirements and the students' individual goals when establishing teaching objectives. Existing text books, however, suffer from an overly tight structure that doesn’t allow the instructor to use additional material in order to focus on the specific needs of the students in a suitable way. Flexible concepts are needed which serve as a framework and which can be realized with texts and tasks focusing on what is required by a specific learning context. This paper presents such an approach, using the German feature film Tatort. Besides ideas for working with the audiovisual material we will present opportunities that come along with the various texts and discussions in media and social networks arising around the film as well as ways for combining these aspects with developing language skills for the academic context.

Tamper indicating gold nanocup plasmonic films

2017-02-13

The spectral signature of nanoplasmonic films are both robust and tailorable with optical responses ranging from the visible to the near-infrared. We present the development of flexible, elastomeric nanoplasmonic films consisting of periodic arrays of gold nanocups as tamper indicating films. Gold nanocups have polarization-sensitive optical properties that may be manufactured into films that offer unique advantages for tamper indication. These flexible films can be made quickly and at low-cost using commercially available monodisperse polystyrene nanospheres through self-assembly followed by plasma etching, metal deposition, and lift-off from a sacrificial substrate. Polarization- and angle-dependent optical spectroscopic measurements were performed to characterize the fabricated films. Using polarization-sensitive hyperspectral imaging, we demonstrate how these films can be applied to tamper indication and counterfeit resistance applications.

Josephson tunnel junctions in niobium films

International Nuclear Information System (INIS)

Wiik, Tapio.

1976-12-01

A method of fabricating stable Josephson tunnel junctions with reproducible characteristics is described. The junctions have a sandwich structure consisting of a vacuum evaporated niobium film, a niobium oxide layer produced by the glow discharge method and a lead film deposited by vacuum evaporation. Difficulties in producing thin-film Josephson junctions are discussed. Experimental results suggest that the lower critical field of the niobium film is the most essential parameter when evaluating the quality of these junctions. The dependence of the lower critical field on the film thickness and on the Ginzburg-Landau parameter of the film is studied analytically. Comparison with the properties of the evaporated films and with the previous calculations for bulk specimens shows that the presented model is applicable for most of the prepared samples. (author)

Solvent annealing induced phase separation and dewetting in PMMA∕SAN blend film: film thickness and solvent dependence.

Science.gov (United States)

You, Jichun; Zhang, Shuangshuang; Huang, Gang; Shi, Tongfei; Li, Yongjin

2013-06-28

The competition between "dewetting" and "phase separation" behaviors in polymer blend films attracts significant attention in the last decade. The simultaneous phase separation and dewetting in PMMA∕SAN [poly(methyl methacrylate) and poly(styrene-ran-acrylonitrile)] blend ultrathin films upon solvent annealing have been observed for the first time in our previous work. In this work, film thickness and annealing solvent dependence of phase behaviors in this system has been investigated using atomic force microscopy and grazing incidence small-angle X-ray scattering (GISAXS). On one hand, both vertical phase separation and dewetting take place upon selective solvent vapor annealing, leading to the formation of droplet∕mimic-film structures with various sizes (depending on original film thickness). On the other hand, the whole blend film dewets the substrate and produces dispersed droplets on the silicon oxide upon common solvent annealing. GISAXS results demonstrate the phase separation in the big dewetted droplets resulted from the thicker film (39.8 nm). In contrast, no period structure is detected in small droplets from the thinner film (5.1 nm and 9.7 nm). This investigation indicates that dewetting and phase separation in PMMA∕SAN blend film upon solvent annealing depend crucially on the film thickness and the atmosphere during annealing.

2012-09-01

Synthetic piezoelectric polymer films produced from petroleum feedstock have long been used as thin-film sensors and actuators. However, the fossil fuel requirements for synthetic polymer production and carbon dioxide emission from its combustion have raised concern about the environmental impact of its continued use. Eco-friendly biomass polymers, such as poly(L-lactic acid) (PLLA), are made from plant-based (vegetable starch) plastics and, thus, have a much smaller carbon footprint. Additionally, PLLA does not exhibit pyroelectricity or unnecessary poling. This suggests the usefulness of PLLA films for the human-machine interface (HMI). As an example of a new HMI, we have produced a TV remote control using a PLLA film. The intuitive operation provided by this PLLA device suggests that it is useful for the elderly or handicapped.

Film-based dual energy radiography

Sandrik, J. M.; Pelc, N. J.

1985-01-01

X-ray energy-difference images are obtained simultaneously by exposing a body to a broad energy spectrum X-ray beam while a radiographic film package is disposed between front and rear X-ray intensifying screens. The film package has two superimposed films with a light-opaque sheet between them. The front screen, on which the polyenergetic image beam emerging from the body is incident, is excited to luminescence by X-ray photons predominantly in one energy band and the rear screen is excited predominantly by photons in another band. The light opaque sheet preferably contains X-ray filter material for additional filtering of photons to increase the fraction of protons at said other band to which the rear screen is sensitive. A shadowgraph of a marker is formed on the film emulsions during X-ray exposure to aid in matching congruent picture elements on each film when the developed films are being read out to obtain signals corresponding to their intensities. Notches in the edges of the films and sheet serve as a code for indicating the type of screens with which the package can be used

Passivation Effects in Copper Thin Films

Wiederhirn, G.; Nucci, J.; Richter, G.; Arzt, E.; Balk, T. J.; Dehm, G.

2006-01-01

We studied the influence of a 10 nm AlxOy passivation on the stress-temperature behavior of 100 nm and 1 μm thick Cu films. At low temperatures, the passivation induces a large tensile stress increase in the 100 nm film; however, its effect on the 1 μm film is negligible. At high temperatures, the opposite behavior is observed; while the passivation does not change the 100 nm film behavior, it strengthens the 1 μm film by driving it deeper into compression. These observations are explained in light of a combination of constrained diffusional creep and dislocation dynamics unique to ultra-thin films

As an imitation of its use in the expression “Film noir” it is nowadays mainly used in order to describe a certain kind of crime literature, while it denotes a certain kind of novel of social criticism in French that has a connec¬tion to crime. But in both cases, concerning film as well as literature, there is no clear definition which makes it difficult, if not impossible, to use it as a scientific term, for instance for ...

In and Ga Codoped ZnO Film as a Front Electrode for Thin Film Silicon Solar Cells

Directory of Open Access Journals (Sweden)

Full Text Available Doped ZnO thin films have attracted much attention in the research community as front-contact transparent conducting electrodes in thin film silicon solar cells. The prerequisite in both low resistivity and high transmittance in visible and near-infrared region for hydrogenated microcrystalline or amorphous/microcrystalline tandem thin film silicon solar cells has promoted further improvements of this material. In this work, we propose the combination of major Ga and minor In impurities codoped in ZnO film (IGZO to improve the film optoelectronic properties. A wide range of Ga and In contents in sputtering targets was explored to find optimum optical and electrical properties of deposited films. The results show that an appropriate combination of In and Ga atoms in ZnO material, followed by in-air thermal annealing process, can enhance the crystallization, conductivity, and transmittance of IGZO thin films, which can be well used as front-contact electrodes in thin film silicon solar cells.

We derive a lumped-element, equivalent-circuit model for the thickness-shear mode (TSM) resonator with a viscoelastic film. This modified Butterworth-Van Dyke model includes in the motional branch a series LCR resonator, representing the quartz resonance, and a parallel LCR resonator, representing the film resonance. This model is valid in the vicinity of film resonance, which occurs when the acoustic phase shift across the film is an odd multiple of pi/2 rad. For low-loss films, this model accurately predicts the frequency changes and damping that arise at resonance and is a reasonable approximation away from resonance. Elements of the parallel LCR resonator are explicitly related to film properties and can be interpreted in terms of elastic energy storage and viscous power dissipation. The model leads to a simple graphical interpretation of the coupling between the quartz and film resonances and facilitates understanding of the resulting responses. These responses are compared with predictions from the transmission-line and Sauerbrey models.

Low-Concentration Indium Doping in Solution-Processed Zinc Oxide Films for Thin-Film Transistors

Full Text Available We investigated the influence of low-concentration indium (In doping on the chemical and structural properties of solution-processed zinc oxide (ZnO films and the electrical characteristics of bottom-gate/top-contact In-doped ZnO thin-film transistors (TFTs. The thermogravimetry and differential scanning calorimetry analysis results showed that thermal annealing at 400 °C for 40 min produces In-doped ZnO films. As the In content of ZnO films was increased from 1% to 9%, the metal-oxygen bonding increased from 5.56% to 71.33%, while the metal-hydroxyl bonding decreased from 72.03% to 9.63%. The X-ray diffraction peaks and field-emission scanning microscope images of the ZnO films with different In concentrations revealed a better crystalline quality and reduced grain size of the solution-processed ZnO thin films. The thickness of the In-doped ZnO films also increased when the In content was increased up to 5%; however, the thickness decreased on further increasing the In content. The field-effect mobility and on/off current ratio of In-doped ZnO TFTs were notably affected by any change in the In concentration. Considering the overall TFT performance, the optimal In doping concentration in the solution-processed ZnO semiconductor was determined to be 5% in this study. These results suggest that low-concentration In incorporation is crucial for modulating the morphological characteristics of solution-processed ZnO thin films and the TFT performance.

Boleslas Matuszewski: Pioneer of medical film-making

Full Text Available Boleslas Matuszewski, born in 1856, was a pioneer in medical film-making. He worked simultaneously on improving his movie camera, film-making, collecting film documentation, and the idea of establishing an archive of medical films. Although his first attempts at filming and showing surgical operations didn't gain widespread approval, he was not discouraged, and succeeded in garnering support from a number of French doctors, who realized the importance of his ideas, not only in filming and forming medical film documentation, but also in the use of film for educative purposes. His visionary ideas gained acceptance when Dr. Doyen, on the occasion of the 66th Convention of the British Medical Society, in 1898, used film material as part of his lecture. Shortly afterwards, the Medical Academy took steps to show certain operative techniques, which represented both the confirmation and fruition of Matuszewski's ideas about filmmaking and the establishment of an archive of medical films.

DLC films with different thicknesses (from 100 nm to 1.9 μm) were deposited using sputtering of graphite target in pure argon atmosphere without substrate heating. Film microstructures (sp 2 /sp 3 ratio) and mechanical properties (modulus, hardness, stress) were characterized as a function of film thickness. A thin layer of aluminum about 60 nm was deposited on the DLC film surface. Laser micromachining of Al/DLC layer was performed to form microcantilever structures, which were released using a reactive ion etching system with SF 6 plasma. Due to the intrinsic stress in DLC films and bimorph Al/DLC structure, the microcantilevers bent up with different curvatures. For DLC film of 100 nm thick, the cantilever even formed microtubes. The relationship between the bimorph beam bending and DLC film properties (such as stress, modulus, etc.) were discussed in details

Alloying behaviour of electroplated Ag film with its underlying Pd/Ti film stack for low resistivity interconnect metallization

International Nuclear Information System (INIS)

Ezawa, Hirokazu; Miyata, Masahiro; Tatsumi, Kohei

2014-01-01

Highlights: • Alloying behavior of Ag/Pd/Ti film stack was studied by annealing at 400-800 °C. • The Ag film resistivity decreased with increasing annealing temperature. • Formation of the Pd-Ti intermetallics was found to be dominant over Ag-Pd alloying. • The excess Ti was consumed to form Ti oxides, which inhibited Ti alloying with Ag. -- Abstract: In this paper, viability of electroplated Ag film into device application was studied. Alloying behavior of the Ag film with its underlying Pd(50 nm)/Ti(100 nm) film stack was investigated with respect to heat treatment at different temperatures from 400 °C to 800 °C in an argon ambient. After annealing at 400 °C, the electrical resistivity of the Ag film increased due to Pd alloying with Ag. Formation of Pd–Ti intermetallic phases became dominant over Ag–Pd alloying with increasing annealing temperature, leading to the resistivity decrease of the Ag film. The resistivity of the 800 °C annealed Ag film approached that of its as-plated Ag film. The excess Ti atoms which were not consumed to form the intermetallic phases with the Pd atoms migrated to the Ag film surface to form Ti oxides along the Ag grain boundaries on the topmost film surface. The Ag/Pd/Ti film stack has been confirmed to maintain the resistivity of the Ag film at as-plated low levels after high temperature annealing. This paper also discusses process integration issues to enable the Ag metallization process for future scaled and three dimensionally chip stacked devices

Purpose. To assess the tear film quantity and correlate it with the quality and stability of the tear film in diabetics and compare them to age matched controls. Introduction. Diabetes affects tear film parameters in multiple ways. Poor metabolic control and neuropathy are postulated factors. To further understand how diabetes affects tear film parameters this study was conducted. Subjects and Methods. Tear meniscus height was measured by anterior segment OCT, along with tear thinning time, a subtype of noninvasive tear break-up time, and blinking rate per minute which were all recorded for 22 diabetic patients. Correlations between these tear film parameters were studied and then compared to 16 age matched controls. Results. A statistically significant difference was found in blinking rate between the diabetic and the control group (P = 0.002), with higher blinking rate among diabetics. All tear film parameters were negatively correlated with duration of diabetes. A positive correlation was found between tear film volume and stability. Conclusion. Diabetes affects the tear film in various ways. Diabetics should be examined for dry eye signs even in absence of symptoms which may be masked by associated neuropathy. Duration of diabetes has an impact on tear film status.

Sericin is a natural silk protein which is removed from silk in a process called degumming. Thus, finding a use for the extracted sericin as a bio polymer film will create added value product which will benefit both the economy and society. The films were manufactured with silk sericin, using different dimethylolurea (DMU) concentrations as cross-linking agent and glycerol as plasticizer. Sericin films produced by crosslinking method were light yellow, homogeneous, transparent and visually attractive. The average film thickness was 0.10 ± 0.02 mm. The bio films show low water solubility (up to 30% of total dry mass), good tension strength and high elongation ability. The water vapor permeability is moderate, typical of highly hydrophilic films. Structural transformations in silk sericin films were analyzed using Fourier transform infrared-attenuated total reflection (FTIR-ATR) spectroscopy and X-ray diffraction. This resulted in aggregated β-sheet structure (peak at 1616 cm-1 in the amide I absorption) by FTIR studies and increasing the DMU concentration in film decreased the peak intensity at 2θ = 20 degree. Sericin-based film properties are dependent on components used to form film, which can used to tailor the desired film flexibility and minimize permeability of films. (author)

The objective of this book is to disseminate the most recent research in Thin Films, Nanomaterials, Corrosion and Metallurgy presented at the International Conference on Advanced Materials (ICAM 2011) held in PSG College of Technology, Coimbatore, India during 12-16 December 2011. The book is a compilation of 113 chapters written by active researchers providing information and critical insights into the recent advancements that have taken place. Important new applications are possible today in the fields of microelectronics, opto-electronics, metallurgy and energy by the application of thin films on solid surfaces. Recent progress in high vacuum technology and new materials has a remarkable effect in thin film quality and cost. This has led to the development of new single or multi-layered thin film devices with diverse applications in a multitude of production areas, such as optics, thermal barrier coatings and wear protections, enhancing service life of tools and to protect materials against thermal and atmospheric influence. On the other hand, thin film process techniques and research are strongly related to the basic research activities in nano technology, an increasingly important field with countless opportunities for applications due to the emergence of new properties at the nanoscale level. Materials and structures that are designed and fabricated at the nano scale level, offer the potential to produce new devices and processes that may enhance efficiencies and reduce costs in many areas, as photovoltaic systems, hydrogen storage, fuel cells and solar thermal systems. In the book, the contributed papers are classified under two sections i) thin films and ii) nanomaterials. The thin film section includes single or multi layer conducting, insulating or semiconducting films synthesized by a wide variety of physical or chemical techniques and characterized or analyzed for different applications. The nanomaterials section deals with novel or exciting materials

Thin diamond films for tribological applications

1989-01-01

Diamond films have been deposited on Si, Mo and many other substrates by microwave and radio frequency plasma enhanced chemical vapor deposition. Although the adhesion between the diamond film and most of the metal substrates is poor due to residual thermal stress from the mismatch of thermal expansion coefficients, the authors have developed processes to promote the growth of uniform and continuous diamond films with enhanced adhesion to metal substrates for tribological applications. The tribological properties of these films are measured using a ring-on-block tribotester. The coefficients of friction of diamond films sliding against a 52100 steel ring under the same experimental conditions are found to be significantly different depending on the morphology, grain size and roughness of the diamond films. However, under all cases tested, it is found that for uniform and continuous diamond films with small grain size of 1-3 micrometers, the coefficient of friction of the diamond film sliding against a steel ring under lubrication of a jet of mineral oil is about 0.04

Film dosimetry for IMRT: sensitivity corrections

Full text: The trend towards conformal, dynamic and intensity modulated radiotherapy treatments has furthered the need for true integrating dosimetry. In traditional radiotherapy, film dosimetry is commonly used. The accuracy and reproducibility of film optical density as an indicator of dose, has been associated with several variables. These include the effects of film specific sensitivity, direction of exposure, chemical processing and film scanner sensitivity. In this study, a procedure is developed to account for these variables, with a particular view to film being used as a dosimeter for conformal treatments. An effective sensitometric curve was established by exposing part of a single sheet of film to known doses. All films were processed together and scanned using a DuoscanT1200 transmission scanner, resulting in 12 bit image files. The images were analysed using Osiris software and the results fitted to the modified Williamson equation: P P s (l - 10 αD ) This yields values of α [film sensitivity], and P s [saturation pixel value], allowing individual dosimetry films to be normalised to this sensitometric calibration curve. For validation, a piece of Kodak X Omat-V film was sealed in a head phantom and exposed to a total of 51 IMRT fields, delivered from 6 gantry angles. The rest of the sheet of film was resealed and exposed to four known doses, providing sensitometric data, specific to this exposure. All films were then processed, scanned and analysed as described above. Observed variations in serial films exposed to 50cGy is in the order of 9% [mean 25.0,standard deviation = 3.2]. The automatic gain of the scanner system typically contributed 4% variation and needs to be carefully monitored. Results indicate that by using the sensitometric data from each exposure, the collective errors can be minimised. The IMRT exposure results confirm that the above process is viable for use in dosimetry for conformal radiation therapy. Copyright (2000) Australasian

Oba, Tatsuya

2012-06-19

We have studied relaxation processes in thin supported films of poly(methyl acrylate) at the temperature corresponding to 13 K above the glass transition by monitoring the reorientation of single perylenediimide molecules doped into the films. The axial position of the dye molecules across the thickness of the film was determined with a resolution of 12 nm by analyzing astigmatic fluorescence images. The average relaxation times of the rotating molecules do not depend on the overall thickness of the film between 20 and 110 nm. The relaxation times also do not show any dependence on the axial position within the films for the film thickness between 70 and 110 nm. In addition to the rotating molecules we observed a fraction of spatially diffusing molecules and completely immobile molecules. These molecules indicate the presence of thin (<5 nm) high-mobility surface layer and low-mobility layer at the interface with the substrate. (Figure presented) © 2012 American Chemical Society.

Antireflection (AR) at the interface between the air and incident window material is paramount to boost the performance of photovoltaic devices. 3D nanostructures have attracted tremendous interest to reduce reflection, while the structure is vulnerable to the harsh outdoor environment. Thus the AR film with improved mechanical property is desirable in an industrial application. Herein, a scalable production of flexible AR films is proposed with microsized structures by roll-to-roll imprinting process, which possesses hydrophobic property and much improved robustness. The AR films can be potentially used for a wide range of photovoltaic devices whether based on rigid or flexible substrates. As a demonstration, the AR films are integrated with commercial Si-based triple-junction thin film solar cells. The AR film works as an effective tool to control the light travel path and utilize the light inward more efficiently by exciting hybrid optical modes, which results in a broadband and omnidirectional enhanced performance.

Technical Note: Homogeneity of Gafchromic EBT2 film

International Nuclear Information System (INIS)

Hartmann, Bernadette; Martisikova, Maria; Jaekel, Oliver

2010-01-01

Purpose: The self-developing Gafchromic EBT film is a radiochromic film, widely used for relative photon dosimetry. Recently, the manufacturer has replaced the well-investigated EBT film by the new Gafchromic EBT2 film. It has the same sensitive component and, in addition, it contains a yellow marker dye in order to protect the film against ambient light exposure and to serve as a base for corrections of small differences in film response. Furthermore, the configuration of the film layers as well as the binder material have been changed in comparison to the EBT film. When investigating the properties of EBT2 film, all characteristics were found to be similar to those of EBT film, except for the film response homogeneity. Thus, in this article special focus was put on examining the homogeneity of EBT2 film. Methods: A scan protocol established for EBT film and published previously was used. The uniformity of the film coloration was investigated for unirradiated and irradiated EBT2 film sheets. The dose response of EBT2 film was measured and the influence of film inhomogeneities on dose determination was evaluated. Results: Inhomogeneities in pixel values of up to ±3.7% within one film were detected. The relative inhomogeneities were found to be approximately independent of the dose. Nonuniformities of the film response lead to uncertainties in dose determination of ±8.7% at 1 Gy. When using net optical densities for dose calibration, uncertainties in dose determination amount to more than ±6%. Conclusions: EBT2 films from the lot investigated in this study show response inhomogeneities, which lead to uncertainties in dose determination exceeding the commonly accepted tolerance levels. It is important to test further EBT2 lots regarding homogeneity before using the film in clinical routine.

Giant magnetoimpedance (GMI) effect on NiFe thin film is very promising due to its application in developing the magnetic field sensors with highly sensitivity and low cost. In this paper, the single layered NiFe thin film and NiFe/Cu/NiFe thin film with a meander structure are prepared by the MEMS technology. The influences of sputtering parameters, film structure and conductor layer width on GMI effect in NiFe single layer and meander NiFe/Cu/NiFe film are investigated. Maximum of the GMI ratio in single layer and sandwich film is 5% and 64%, respectively. The results obtained are useful for developing the high-performance magnetic sensors based on NiFe thin film.

An Ag-C thin film was prepared by DC magnetron co-sputtering, using pure silver and graphite as the targets. The microstructure and morphology of the deposited thin film were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Electrochemical performances of the Ag-C thin film anode were investigated by means of discharge/charge and cyclic voltammogram (CV) tests in model cells. The electrochemical impedance spectrum (EIS) characteristics and the chemical diffusion coefficient, D Li of the Ag-C thin film electrode at different discharging states were discussed. It was believed that the excellent cycling performance of the Ag-C electrode was ascribed to the good conductivity of silver and the volume stability of the thin film

Highlights: ► Nanoscale data on growth, structure and local properties of passive films reviewed. ► Preferential role of defects of passive films on the corrosion resistance emphasized. ► Effect of grain boundaries on local electronic properties shown by new data. ► Use of atomistic modeling to test mechanistic hypotheses illustrated. - Abstract: The nanometer scale chemical and structural aspects of ultrathin oxide passive films providing self-protection against corrosion to metals and alloys in aqueous environments are reviewed. Data on the nucleation and growth of 2D anodic oxide films, details on the atomic structure and nanostructure of 3D passive films, the preferential role of surface step edges in dissolution in the passive state and the preferential role of grain boundaries of the passive films in passivity breakdown are presented. Future perspectives are discussed, and exemplified by new data obtained on the relationship between the nanostructure of oxide passive films and their local electronic properties. Atomistic corrosion modeling by ab initio density functional theory (DFT) is illustrated by the example of interactions of chloride ions with hydroxylated oxide surfaces, including the role of surface step edges. Data obtained on well-defined substrate surfaces with surface analytical techniques are emphasized.

The composition of a radiographic film gives its values of speed, spatial resolution and base density. The technical knowledge allows to predict how a film with a known composition works, and simulate how this film will work with changes in composition and exposure. In this paper, characterization of films composed by different emulsions was realized, in a way to know the characteristic curve, and to study how the format, organization and concentration of silver salt crystals set the radiographic film images.This work aims to increase an existing simulator, where parallel programming was used to simulate X-ray fluorescence processes. The setup of source and X-ray interactions with objects stills the same, and the detector constructed in this work was placed to form images. At first, considering the approach that the film is a square matrix where each element has a specific quantity of silver grains, that each grain fills a specific area, and that each interaction to radiation transforms a salt silver grain in to metallic silver grain (black grain), we have a blackening standard, and it should show how is the behavior of a optic density in a specific area of the film. Each matrix element has a degree of blackening, and it is proportional to the black grains area. (author)

Objectives. We compared the prevalence of condom use during a variety of sexual acts portrayed in adult films produced for heterosexual and homosexual audiences to assess compliance with state Occupational Health and Safety Administration regulations. Methods. We analyzed 50 heterosexual and 50 male homosexual films released between August 1, 2005, and July 31, 2006, randomly selected from the distributor of 85% of the heterosexual adult films released each year in the United States. Results. Penile–vaginal intercourse was protected with condoms in 3% of heterosexual scenes. Penile–anal intercourse, common in both heterosexual (42%) and homosexual (80%) scenes, was much less likely to be protected with condoms in heterosexual than in homosexual scenes (10% vs 78%; P films. Conclusions. Heterosexual films were much less likely than were homosexual films to portray condom use, raising concerns about transmission of HIV and other sexually transmitted diseases, especially among performers in heterosexual adult films. In addition, the adult film industry, especially the heterosexual industry, is not adhering to state occupational safety regulations. PMID:19218178

Oxygen diffusion in bilayer polymer films

Experiments to quantify oxygen diffusion have been performed on polymer samples in which a film of poly(ethylene-co-norbornene) was cast onto a film of polystyrene which, in turn, was cast onto an oxygen-impermeable substrate. In the technique employed, the time evolution of oxygen transport...... through the film of poly(ethylene-co-norbornene) and into the polystyrene film was monitored using the phosphorescence of singlet oxygen as a spectroscopic probe. To analyze the data, it was necessary to solve Fick's second law of diffusion for both polymer films. Tractable analytical and numerical...

Marangoni elasticity of flowing soap films

Science.gov (United States)

Kim, Ildoo; Mandre, Shreyas

2017-08-01

We measure the Marangoni elasticity of a flowing soap film to be 22 mN/m irrespective of its width, thickness, flow speed, or the bulk soap concentration. We perform this measurement by generating an oblique shock in the soap film and measuring the shock angle, flow speed, and thickness. We postulate that the elasticity is constant because the film surface is crowded with soap molecules. Our method allows nondestructive measurement of flowing soap film elasticity and the value 22 mN/m is likely applicable to other similarly constructed flowing soap films.

Small contents of organoclays (1 wt %) were incorporated to PP modified with maleic anhydride by melt intercalation, in order to prepare polymeric films for further applications in food package sector. The films were characterized by X-ray diffraction (XRD) and mechanical properties. The data indicates that the incorporation of organoclay to PP results in transparent films with intercalated morphology and highly. The mechanical properties of nanocomposites films were superior from those pristine films. The results evidences that the PP/PP-g-MA/organoclay nanocomposite films, prepared in this study might be promissory to the food package market and, in short time, be used like a new product by industries of this sector.

In the framework of the present thesis the fast lattice heating in thin metal and bismuth layers after optical short-pulse excitation was studied. By irradiation of ultrathin solid films with ultrashort (femtosecond) laser pulses for sort times an extreme nonequilibrium state occurs: The electronic system is strongly excited, while the lattice system remains cold. An energetic exchange between both systems follows, which is based on the electron-phonon interaction and leads to heating of the lattice system. This lattice heating can be observed by means of the Debye-Waller effect in the electron diffraction image. By means of the excitation-interrogation scheme by a series of moment records this lattice heating can be observed time-resolvedly. The experimentally determind time scales for this process permit conclusions on the electron-phonon coupling in the studied materials. In this thesis a time-resolving transmissi9on-electron diffraction experiment with sub-picosecond time resolution was constructed and optimized. By means of this experiment the fast lattice heating in thin gold, silver, copper, and bismuth films was studied. The observed heating behaviour of the metal films shows agreement with theoretical predictions of different model calculations. The results of the measurements on bismuth films show a hitherto not observed coupling behaviour.

With the growth of 3D packaging technology and the development of flexible, transparent electrodes, the use of multilayer thin-films is steadily increasing throughout high-tech industries including semiconductor, flat panel display, and solar photovoltaic industries. Also, this in turn leads to an increase in industrial demands for inspection of internal analysis. However, there still remain many technical limitations to overcome for measurement of the internal structure of the specimen without damage. In this paper, we propose an innovative optical inspection technique for simultaneous measurements of the surface and film thickness corresponding to each layer of multilayer film structures by computing the phase and reflectance over a wide range of wavelengths. For verification of our proposed method, the sample specimen of multilayer films was fabricated via photolithography process, and the surface profile and film thickness of each layer were measured by two different techniques of a stylus profilometer and an ellipsometer, respectively. Comparison results shows that our proposed technique enables simultaneous measurements of the top surface and its underlying film surfaces with high precision, which could not be measured by conventional non-destructive methods.

The International Young Physicists’ Tournament (IYPT) is a worldwide annual competition for high-school students. This paper is adapted from the solution to problem 8, Jet and Film, as presented by the Singapore Team at the 26th IYPT, Taipei, Taiwan. The impact of liquid microjets on stable soap films was investigated. Two steady regimes were observed: refraction (where the microjet penetrates the soap film and is deflected) and absorption (where the microjet merges with the soap film and forms vertical undulating patterns on the soap film surface). This phenomenon has potential applications in controlling the trajectory of a liquid microjet in air. Although Kirstetter et al (2012) investigated this interaction by using the same liquid for both the microjet and the soap film, this paper extends their work by using different liquids for the microjet and the soap film. In addition, the need for a small-angle approximation of Snell’s law is removed for the refraction regime, and an alternative expression is proposed for the force exerted by the soap film on the microjet in the absorption regime that accounts for the dependence of the wavelength of the undulating patterns on the angle of incidence of the microjet on the soap film. Empirical data support these improved theoretical predictions.

Full Text Available Purpose. To assess the tear film quantity and correlate it with the quality and stability of the tear film in diabetics and compare them to age matched controls. Introduction. Diabetes affects tear film parameters in multiple ways. Poor metabolic control and neuropathy are postulated factors. To further understand how diabetes affects tear film parameters this study was conducted. Subjects and Methods. Tear meniscus height was measured by anterior segment OCT, along with tear thinning time, a subtype of noninvasive tear break-up time, and blinking rate per minute which were all recorded for 22 diabetic patients. Correlations between these tear film parameters were studied and then compared to 16 age matched controls. Results. A statistically significant difference was found in blinking rate between the diabetic and the control group (P=0.002, with higher blinking rate among diabetics. All tear film parameters were negatively correlated with duration of diabetes. A positive correlation was found between tear film volume and stability. Conclusion. Diabetes affects the tear film in various ways. Diabetics should be examined for dry eye signs even in absence of symptoms which may be masked by associated neuropathy. Duration of diabetes has an impact on tear film status.

Ballistic transport model for target-to-substrate atom transfer during magnetron sputter deposition was used to develop zinc target (cathode) configuration that enabled growth of uniform zinc oxide films on extensive surfaces and provided reproducibility of films characteristics irrespective of the cathode wear-out. The advantage of the developed target configuration for high-quality ZnO film deposition was observed in the sputtering pressure range of 5− 50 mTorr, and in the range of cathode-to-substrate distances 7–20 cm. Characteristics of the deposited films were demonstrated by using X-ray diffraction analysis, as well as optical and electrical measurements. - Highlights: • Change of target configuration for optimization of magnetron sputtering deposition is proposed. • Improvement of ZnO film properties due to use of this target is demonstrated. • This configuration provided reproducibility of the deposited films properties.

Abstract: This article explores two central uses of memory narratives in film fan culture: Firstly; that fan magazines recycle and reiterate popular histories of film, with the extensive detailing of anecdotes and histories of productions serving to fix certain texts as canonical, cult or classic film artefacts whilst legitimating nostalgia as a mode of reading; secondly; that such films are historically positioned in terms of an appeal to fans via nostalgia as activating personal and affective histories of pleasurable film reception. This piece examines the various ways that commercial magazines discursively utilise nostalgia in their mediation between texts, institutions and fan audiences. At the same time it also explores that way that nostalgia resonates within the activities and discourses of fans as they engage with film.

We analyzed image factors to determine the characteristic factors that need for intelligent replenishment system of the auto film processor. We processed the serial 300 sheets of radiographic films of chest phantom without replenishment of developing and fixation replenisher. We took the digital data by using film digitizer which scanned the films and automatically summed up the pixel values of the films. We analyzed characteristic curves, average gradients and relative speeds of individual film using densitometer and step densitometry. We also evaluated the pH of developer, fixer, and washer fluid with digital pH meter. Fixer residual rate and washing effect were measured by densitometer using the reagent methods. There was no significant reduction of the digital density numbers of the serial films without replenishment of developer and fixer. The average gradients were gradually decreased by 0.02 and relative speeds were also gradually decreased by 6.96% relative to initial standard step-densitometric measurement. The pHs of developer and fixer were reflected the inactivation of each fluid. The fixer residual rates and washing effects after processing each 25 sheets of films were in the normal range. We suggest that the digital data are not reliable due to limitation of the hardware and software of the film digitizer. We conclude that average gradient and relative speed which mean the film's contrast and sensitivity respectively are reliable factors for determining the need for the replenishment of the auto film processor. We need more study of simpler equations and programming for more intelligent replenishment system of the auto film processor.

The members of the Tear Film Subcommittee reviewed the role of the tear film in dry eye disease (DED). The Subcommittee reviewed biophysical and biochemical aspects of tears and how these change in DED. Clinically, DED is characterized by loss of tear volume, more rapid breakup of the tear film and increased evaporation of tears from the ocular surface. The tear film is composed of many substances including lipids, proteins, mucins and electrolytes. All of these contribute to the integrity of the tear film but exactly how they interact is still an area of active research. Tear film osmolarity increases in DED. Changes to other components such as proteins and mucins can be used as biomarkers for DED. The Subcommittee recommended areas for future research to advance our understanding of the tear film and how this changes with DED. The final report was written after review by all Subcommittee members and the entire TFOS DEWS II membership. Copyright © 2017 Elsevier Inc. All rights reserved.

Intrinsic work function of molecular films

International Nuclear Information System (INIS)

Ivančo, Ján

2012-01-01

The electronic properties of molecular films are analysed with the consideration of the molecular orientation. The study demonstrates that surfaces of electroactive oligomeric molecular films can be classified—analogously to the elemental surfaces—by their intrinsic work functions. The intrinsic work function of molecular films is correlated with their ionisation energies; again, the behaviour is analogous to the correlation existing between the first ionisation energy of elements and the work function of the corresponding elemental surfaces. The proposed intrinsic work-function concept suggests that the mechanism for the energy-level alignment at the interfaces associated with molecular films is virtually controlled by work functions of materials brought into the contact. - Highlights: ► Molecular films exhibit their own (intrinsic) work function. ► Intrinsic work function is correlated with ionisation energy of molecular films. ► Intrinsic work function determines dipole at interface with a particular surface. ► Surface vacuum-level change upon film growth does not relate to interfacial dipole.

Heterostructured polymer Langmuir-Blodgett (LB) film prepared by using poly(N-dodecylacrylamide-co-t-butyl 4-vinylphenyl carbonate) (p(DDA-tBVPC53)) and poly(N-neopentyl methacrylamide-co-9-anthrylmethyl methacrylate) (p(nPMA-AMMA10)) polymer LB films which can act as photogenerator layers were investigated. Patterns with a resolution of 0.75 μm were obtained on heterostructured polymer LB films composed of 4 layers of p(nPMA-AMMA10) LB film (top layers) and 40 layers of p(DDA-tBVPC53) LB film (under layers) on a silicon wafer by deep UV irradiation followed by development with 1% tetramethylammonium hydroxide aqueous solution. The sensitivity of the heterostructured polymer LB films was improved without loss of the resolution compared with p(DDA-tBVPC53) LB film. The etch resistance of the heterostructured polymer LB films was sufficiently good to allow patterning of a copper film suitable for photomask fabrication

Holographic tracking of quantized intra-film segments during interferometric laser processing of SiOx thin films(Conference Presentation)

Science.gov (United States)

Ho, Stephen; Domke, Matthias; Huber, Heinz P.; Herman, Peter P.

2017-03-01

Interferometric femtosecond laser processing of thin dielectric films has recently opened the novel approach for quantized nanostructuring from inside the film, driven by the rapid formation of periodic thin nanoscale plasma disks of 20 to 45 nm width, separated on half-wavelength, λ/2nfilm, spacing (refractive index, nfilm). The nano-disk explosions enable intra-film cleaving of subwavelength cavities at single or multiple periodic depths, enabling the formation of intra-film blisters with nanocavities and the digital ejection at fractional film depths with quantized-depth thickness defined by the laser wavelength. For this paper, the physical mechanisms and ablation dynamics underlying the intra-film cleavage of SiOx thin films were investigated by laser pump-probe microscopy with high temporal dynamic range recorded in a wide time-frame between 100 fs and 10 μs. The long time scales revealed a new observation method as Newton's Rings (observed 50 ns) of the laser-ablated film fragments. For the first time to our knowledge, the holographic tracking reveals the clustering of large mechanically ejected nano-film planes into distinct speed groups according to the multiple of λ/2nfilm in the film. The observation verifies a new `quantized' form of photo-mechanical laser "lift-off".

Heteroepitaxial growth and strain relaxation were investigated in non-polar a-plane (1 1 -2 0)ZnO films grown on r-plane (1 0 -1 2)sapphire substrates in the temperature range 200-700 deg. C by pulsed laser deposition. The lattice misfit in the plane of the film for this orientation varied from -1.26% in [0 0 0 1] to -18.52% in the [-1 1 0 0] direction. The alignment of (1 1 -2 0)ZnO planes parallel to (1 0 -1 2)sapphire planes was confirmed by X-ray diffraction θ-2θ scans over the entire temperature range. X-ray φ-scans revealed the epitaxial relationship:[0 0 0 1]ZnO-parallel [-1 1 0 1]sap; [-1 1 0 0]ZnO-parallel [-1 -1 2 0]sap. Depending on the growth temperature, variations in the structural, optical and electrical properties were observed in the grown films. Room temperature photoluminescence for films grown at 700 deg. C shows a strong band-edge emission. The ratio of the band-edge emission to green band emission is 135:1, indicating reduced defects and excellent optical quality of the films. The resistivity data for the films grown at 700 deg. C shows semiconducting behavior with room temperature resistivity of 2.2 x 10 -3 Ω-cm.

To optimize the performance of silver nanowire (Ag NW) film heaters and explore the effect of graphene on a film, we introduced poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) and graphene modified with ethyl cellulose (graphene-EC) into the film. The high-quality and well-dispersed graphene-EC was synthesized from graphene obtained by electrochemical exfoliation as a precursor. The transparent film heaters were fabricated via spin-coating. With the assistance of graphene-EC, the stability of film heaters was greatly improved, and the conductivity was optimized by adjusting the Ag NW concentration. The film heaters exhibited a fast and accurate response to voltage, accompanied by excellent environmental endurance, and there was no significant performance degradation after being operated for a long period of time. These results indicate that graphene-EC plays a crucial role in optimizing film stability and heat dispersion in the film. The Ag NW/PEDOT:PSS-doped graphene-EC film heaters show a great potential in low-cost indium-tin-oxide-free flexible transparent electrodes, heating systems, and transparent film heaters.

requirement. (orig.) [German] Hintergrund: Die Radiotherapie bringt Tumorpatienten in eine besondere Lebenssituation, in der sie eine Reihe von unterschiedlichen Faktoren ausgesetzt werden, deren Auspraegung weitgehend unbekannt ist. Intention dieser Querschnittsstudie war es, erstmals systematisch die spezifischen Belastungen von Tumorpatienten zu Beginn einer Strahlentherapie aufzuzeigen und einen belastungsabhaengigen Betreuungswunsch zu erheben mit dem Ziel einer Belastungsreduktion und Verbesserung von Lebensqualitaet und Compliance waehrend einer radioonkologischen Behandlung. Patienten und Methoden: 732 Patienten wurden zunaechst in die Studie aufgenommen, von denen 446 (60,9%) die Einschlusskriterien erfuellten (Ablehnung 21,0%, Karnofsky-Index 6,6%, organisatorische Probleme 3,4%, Sprachbarrieren 3,0%, kognitive Einschraenkung 2,6%, Tod 2,5%).

We have developed a biodegradable polymer scaffold made of a polycaprolactone/polylactic acid (PCL/PLA) film. Surface properties such as topography and chemistry have a vital influence on cell–material interactions. Surface modifications of PCL/PLA films were performed using topographical cues and UV–ozone treatment to improve Schwann cell organisation and behaviour. Schwann cell attachment, alignment and proliferation were evaluated on the grooved UV–ozone treated and non-treated films. Solvent casting of the polymer solution on patterned silicon substrates resulted in films with different groove shapes: V (V), sloped (SL) and square (SQ) shapes. Pitted films, with no grooves, were prepared as a negative control. The UV–ozone treatment was performed to increase hydrophilicity. The process specifications for UV–ozone treatment were evaluated and 5 min radiation time and 6 cm distance to the UV source were suggested as the optimal practise. When cultured on grooved films, Schwann cells elongated on the V and SL shape grooves without crossing over, and grew in the direction of the grooves. However, there was less elongation with more crossing over on the SQ shape grooves. The maximum cell length (511 μm) was observed on the treated V-grooved films. The cells cultured on pitted UV–ozone treated surfaces showed random arrangements with no increase in length. We have demonstrated that the synergic effects of physical cues combined with UV–ozone treatment have the potential to enhance Schwann cell morphology and alignment. (paper)

The electronic structure of thin (≤30 A) free-standing ideal films of Si(001), Si(110), and GaAs(110) is calculated using a plane-wave pseudopotential description. Unlike the expectation based on the simple effective-mass model, we find the following. (i) The band gaps of (001) quantum films exhibit even-odd oscillation as a function of the number N of monolayers. (ii) In addition to sine-type envelope functions which vanish at the film boundaries, some states have cosine envelope functions with extrema at boundaries. (iii) Even-layer Si(001) films exhibit at the valence-band maximum a state whose energy does not vary with the film thickness. Such zero confinement states have constant envelope throughout the film. (iv) Optical transitions in films exhibit boundary-imposed selection rules. Furthermore, oscillator strengths for pseudodirect transitions in the vicinity of forbidden direct transitions can be enhanced by several orders of magnitude. These findings, obtained in direct supercell calculations, can be explained in terms of a truncated crystal (TC) analysis. In this approach the film's wave functions are expanded in terms of pairs of bulk wave functions exhibiting a destructive interference at the boundaries. This maps the eigenvalue spectra of a film onto the bulk band structure evaluated at special k points which satisfy the boundary conditions. We find that the TC representation reproduces accurately the above-mentioned results of direct diagonalization of the film's Hamiltonian. This provides a simple alternative to the effective-mass model and relates the properties of quantum structures to those of the bulk material

After an experimental phase of many years, 3D filming is now effective and successful. Improvements are still possible, but the film industry achieved memorable success on 3D movie’s box offices due to the overall quality of its products. Special environments such as space (“Gravity” ) and the underwater realm look perfect to be reproduced in 3D. “Filming in space” was possible in “Gravity” using special effects and computer graphic. The underwater realm is still difficult to be handled. Unde...

Thin film of polymer is used as coating layer and the corrosion of metal/metal oxide layer is studied with the variation of the thickness of the coating layer. The thin layer of polystyrene is fabricated using spin coating method on copper oxide (CuO) film which is deposited on glass substrate using DC magnetron sputtering technique. Thickness of the polystyrene and the CuO layers are determined using X-ray reflectivity (XRR) technique. CuO thin films coated with the polystyrene layer are exposed to acetic acid (2.5 v/v% aqueous CH3COOH solution) environments and are subsequently analyzed using UV-Vis spectroscopy and atomic force microscopy (AFM). Surface morphology of the film before and after interaction with the acidic environment is determined using AFM. Results obtained from the XRR and UV-Vis spectroscopy confirm that the thin film of polystyrene acts as an anticorrosion coating layer and the strength of the coating depends upon the polymer layer thickness at a constant acid concentration.
