    Janetzky, B.

    2001-07-01

    A numerical model for the transient, free surface flow is implemented in a Finite-Element program for the unsteady calculation of incompressible flow with free surface. The program is used to calculate the flow in different components of a hydraulic turbine, the Pelton turbine. The movement of the fluid with free surface is described mathematically by introducing a partial differential equation for the volume fraction. This equation is simply a transport equation for f, i.e. the volume fraction is advected with the flow in time. The equations is solved numerically. (orig.) [German] Es wird ein Verfahren zur Modellierung von veraenderlichen, freien Oberflaechen vorgestellt und in einem Finite-Elemente-Programm zur numerischen Berechnung von instationaeren, inkompressiblen Stroemungen implementiert. Die veraenderliche, freie Oberflaeche wird mit einem Volume-Of-Fluid Ansatz erfasst. Zur Approximierung der freien Oberflaeche werden stueckweise konstante oder gestufte Verlaeufe im Element angesetzt. Es werden die Eigenschaften des Verfahrens an ausgewaehlten Beispielen mit freier Oberflaeche untersucht. Das erweiterte Programm wird auf instationaere Stroemungen mit freier Oberflaeche in einer hydraulischen Maschine, der Peltonturbine, angewandt. (orig.)

    Full Text Available Dieser Beitrag skizziert ein Konzept zur Sprachstandsermittlung, das aufbauend auf Ergebnissen der gebrauchsbasierten Spracherwerbsforschung die sprachlichen Fähigkeiten von Vorschulkindern in quasi-natürlichen Gesprächssituationen misst. Den Maßstab bilden dabei die altersgemäßen Deutschkompetenzen monolingualer und bilingualer Kinder im Vorschulalter. Mit dem neuen Verfahren soll eine akkurate Bewertung der kommunikativen Kompetenzen der Kinder am Übergang zur Schule erfolgen, die eine systematische Benachteiligung mehrsprachig aufwachsender Kinder aufgrund von Vergleichen mit zielsprachlichen Erwachsenennormen vermeidet. Das neuartige Erhebungsverfahren wird dabei in Form einer digitalen Spielumgebung (App entwickelt, die eine Umsetzung der Prinzipien des handlungsorientierten Sprachenlernens erlaubt. This paper presents the implementation of a new concept of first and second language assessment for pre-school children between four and six years. The concept is theoretically grounded in usage-based linguistics. It assesses language in authentic communicative settings in a game based app. The settings provide the children with incentives to engage in communication. As a result, the assessment tool does not evaluate formal aspects of language. Instead it relies on functional categories for evaluation. Norms for evaluations are derived from longitudinal corpus studies of authentic child language production. The goal of the new approach is to generate an accurate and fair assessments of the children’s communicative capacities. Pilot studies indicate that children with L2 German appear to be more advanced than shown by traditional form-based assessment methods.

    oder Rhythmusstoerungen koennen sich im Rahmen einer Pneumonie entweder neu manifestieren oder infektbedingt verschlimmert werden. Eine fruehzeitige Diagnose und Therapie dieser teils lebensbedrohlichen Komplikationen sind entscheidend und beeinflussen den Therapieerfolg massgeblich. Zu den wichtigsten bildgebenden Verfahren zaehlen das Lungenroentgen und die Computertomographie des Thorax. Eine eindeutige Charakterisierung der Pathologie ist sowohl im Lungenroentgen als auch in der CT manchmal schwierig oder gar nicht moeglich, trotzdem ergeben sich wichtige Hinweise auf intra- und extrapulmonale Komplikationen einer Pneumonie, die mithilfe der Radiologie fruehzeitig erkannt werden koennen. Als zusaetzliche portable Untersuchungsmodalitaet direkt am Patienten eignet sich der Pleuraultraschall zur weiteren Diagnosesicherung und Interventionshilfestellung. Das Lungenroentgen ist sowohl als unkomplizierte initiale Bildgebung als auch zur Kontrolle des Therapieverlaufs wichtig. Bei Verdacht auf Komplikationen, Fortschreiten der Erkrankung oder Diskrepanz zur klinischen Symptomatik sollte eine weiterfuehrende CT des Thorax durchgefuehrt werden. (orig.)

    In order to keep German brown coal competitive, new technologies for enhanced efficiency of power generation from brown coal were developed in the past few years. At a water content of 50-60 percent by weight, much energy is lost for evaporation. Reduction of the water content will incur a 5 percent effiency enhancement. A new process was developed at Dortmund university, i.e. mechanical/thermal dehydration in which the water contained in brown coal is removed by heat and mechanical pressure. The process is described, and its applicability for other moist fuels, e.g. peat or waste from the paper and wood processing industry ist discussed. (orig./SR) [Deutsch] Damit Braunkohle in Deutschland als heimischer und subventionsfreier Energietraeger diesen Stellenwert behaupten und in Zukunft weiter ausbauen kann, wurde in den letzten Jahren verstaerkt die Entwicklung neuer Technologien zur Effizienzsteigerung der Braunkohleverstromung vorangetrieben. Bei der Verbrennung von Braunkohlen mit Wassergehalten von 50-60 Gew.-% ist in herkoemmlichen Kraftwerken ein erheblicher Teil des Energieinhaltes zur Verdampfung des Wassers mit Hilfe von heissen Rauchgasen in sogenannten Mahltrockungsanlagen erforderlich. Durch eine energetisch guenstige Reduzierung des Wassergehaltes vor der Verbrennung sind hier Wirkungsgradsteigerungen um bis zu 5 Prozentpunkte moeglich. Ein neues, fuer diese Aufgabenstellung einsetzbares Verfahren ist das am Lehrstuhl Energieprozesstechnik und Stroemungsmechanik der Universitaet Dortmund entwickelte Mechanisch/Thermische Entwaesserungsverfahren (MTE-Verfahren). Durch die kombinierte Anwendung von Waerme und mechanischem Druck laesst sich das in der Kohle enthaltene Wasser in fluessiger Form entfernen. Neben der Darstellung des MTE-Verfahrens am Beispiel von Braunkohle soll im folgenden auch auf die Moeglichkeiten der Anwendung des Verfahrens fuer andere feuchte Brennstoffe wie Torf und Abfaelle aus der Papier- und Holzverarbeitung eingegangen werden

    The management of solitary lung nodules poses a common clinical problem and biopsy is often required. Several guidelines provide slightly different recommendations and there are no uniform recommendations regarding the ideal technique of puncture guidance (e.g. percutaneous versus bronchoscopic or thoracoscopic). Fine needle aspiration biopsy (FNA) and core biopsy are well established techniques. Both can be performed under CT and to some extent ultrasound guidance. Diagnostic accuracies of FNA and core biopsy for malignant lesions are around 95 %. Core biopsy is superior to FNA for establishing a specific diagnosis with a diagnostic yield of 81-88 % versus 17-21 %. In clinical routine practice core biopsy is the superior tool when compared to FNA. Central lesions in close proximity to bronchi may be biopsied with endobronchial ultrasound (EBUS)-guided bronchoscopy. In all other lesions percutaneous, ideally CT-guided biopsy should be the method of first choice. (orig.) [German] Solitaere Lungenrundherde stellen ein haeufiges differenzialdiagnostisches Problem dar, das oftmals mit der Bildgebung alleine nicht endgueltig zu loesen ist und eine Biopsie erfordert. Die Indikation zur Biopsie variiert zwischen den Leitlinien, und die beste Technik der Biopsie (perkutan vs. bronchoskopisch vs. thorakoskopisch) ist oftmals nicht eindeutig. Feinnadelaspirations- (FNA) und Stanzbiopsie stehen als lange etablierte Standardtechniken zur Verfuegung. Beide koennen CT- und bedingt ultraschallgesteuert durchgefuehrt werden. Die diagnostische Aussagekraft fuer die Diagnose maligner Tumoren liegt fuer beide Techniken bei 95 %. Die Stanzbiopsie ist jedoch der FNA fuer die spezifische Diagnose benigner Prozesse mit einer Genauigkeit von 82-88 vs. 17-21 % ueberlegen. Die Stanzbiopsie ist gegenueber der FNA das in der klinischen Routine ueberlegene Werkzeug. Bei sehr zentralen Herden in Nachbarschaft zu einem Bronchus kann primaer eine bronchoskopische EBUS-gesteuerte (endobronchialer

    Waste treatment prior to fermentation is a key aspect in achieving economic efficiency. One process is presented here in particular: percolation, in which waste is hydrolyzed aerobically, treated mechanically, and washed out with the aid of process water. The process involves a percolation stage followed by a fermentation stage. The process water burdened with organic matter is passed into a fermentation reactor in which the organic components are reacted anaerobically into biogas and bacterial mass, and the process water is recirculated into the percolation reactor. (orig.) [German] Vergaerungstechnologien zaehlen zu den etablierten Verfahren zur Gewinnung regenerativer Energien aus Biomasse. Fuer die Energieeffizienz dieser Verfahren sind die Leistung der Vergaerungsstufe, die Hoehe der Verfuegbarkeit der anaerob abzubauenden organischen Substanzen und der spezifische Energiebedarf des Behandlungsverfahrens massgeblich. Eine Schluesselstellung fuer die Optimierung beider Faktoren nimmt die Abfallaufbereitung vor der Vergaerung ein. Eine Technoloie zur Aufbereitung vor der Vergaerung basiert auf dem Verfahren der Perkolation, in der der Abfall aerob hydrolysiert,mechanisch aufgeschlossen und durch Zugabe von Prozesswasser ausgewaschen wird. Das Verfahren besteht aus einer Aufbereitung - der Perkolation - sowie einer nachgeschalteten Vergaerung. Das mit vergaerbarer Organik beladene Prozesswasser wird einem Vergaerungsreaktor zugefuehrt, in dem die organischen Komponenten anaerob zu Biogas und Bakterienmasse umgesetzt werden. Das aufbereitete Prozesswasser wird anschliessend wieder dem Perkolationsreaktor zugefuehrt. (orig.)

    The law for recycling and waste demands the utilization also for waste of asbestos cement (ac). The procedure of thermal utilization of ac in the flame of a rotary cement kiln was developed and patented by the research institute IBU-tec Weimar, Germany. The ac-material has to be pre-pulverized and grinded to a degree of fineness of R{sub 90}<15%. Considerations of safety engineering lead to the idea of common fine grinding of old oil (oo) and ac. This new procedure was searched in FuE-project in 1998/99 (financial support by BMBF). A mash of ac and oo was generated as a utilization product ready for firing which was injected into the flame of the rotary cement kiln. This particles of ac smelt to spherical shaped particles at a temperature above 1500 C. They were utilized by clinker formation. The material and gas stream leaving the kiln does not contain fibres of asbestos. This was demonstrated in a small equipment burning test. The industrial realization concerning cement plant Ruedersdorf, near Berlin, was searched, technologically described and safety engineeringly and financially assessed by a project study. Process-technical and financial advantages were seen for the dry fine grinding. The wet fine grinding with old oil could be used in cement plants using old oil as fuel. (orig.)

    In recent years magnetic resonance imaging (MRI) has been increasingly established in the diagnosis of prostate cancer in addition to transrectal ultrasonography (TRUS). The use of T2-weighted imaging allows an exact delineation of the zonal anatomy of the prostate and its surrounding structures. Other MR imaging tools, such as dynamic contrast-enhanced T1-weighted imaging or diffusion-weighted imaging allow an inference of the biochemical characteristics (multiparametric MRI). Prostate cancer, which could only be diagnosed using MR imaging or lesions suspected as being prostate cancer, which are localized in the anterior aspect of the prostate and were missed with repetitive TRUS biopsy, need to undergo MR guided biopsy. Recent studies have shown a good correlation between MR imaging and histopathology of specimens collected by MR-guided biopsy. Improved lesion targeting is therefore possible with MR-guided biopsy. So far data suggest that MR-guided biopsy of the prostate is a promising alternative diagnostic tool to TRUS-guided biopsy. (orig.) [German] Neben dem transrektalen Ultraschall (TRUS) hat sich in den letzten Jahren die MRT als nichtinvasive Methode zur Bildgebung von Prostatatumoren etabliert. Mittels T2-gewichteter Sequenzen ist eine exakte anatomische Darstellung der Prostata und ihrer umliegenden Strukturen moeglich.

    The following article reviews nuclear medicine techniques which can be used for assessment of endocrine disorders of the hypothalamic-pituitary axis. For planar and SPECT imaging somatostatin-receptor- and dopamine-D2-receptor-scintigraphy are the most widely distributed techniques. These nuclear medicine techniques may be indicated in selected cases to answer differential diagnostic problems. They can be helpful to search for presence and localization of receptor positive tissue. Furthermore they can detect metastasis in the rare cases of a pituitary carcinoma. Scintigraphy with Gallium-67 is suitable for further diagnostic evaluation in suspected hypophysitis. Other SPECT radiopharmaca do not have relevant clinical significance. F-18-FDG as PET radiopharmacon is not ideal because obvious pituitary adenomas could not be visualized. Other PET radiopharmaca including C-11-methionine, C-11-tyrosine, F-18-fluoroethylspiperone, C-11-methylspiperone, and C-11-raclopride are available in specialized centers only. Overall indications for nuclear medicine in studies for the assessment of endocrine disorders of the hypothalamic-pituitary-axis are rare. Original studies often report only about a small number of patients. According to the authors' opinion the relevance of nuclear medicine in studies of clinically important endocrinologic fields, e. g. localization of small ACTH-producing pituitary adenomas, tumor localization in ectopic ACTH syndrome, localization of recurrent pituitary tissue, assessment of small incidentalomas, can not be definitely given yet.

    -Anhydrit untersucht. Die Reaktion erfolgt mit feuchtem, feinteiligem REA-Gips unter der katalytischen Wirkung kleiner Mengen Schwefelsaeure bei Temperaturen um 100 bis 200 C. Es wird wasserfreier REA-Anhydrit mit orthorhombischer Kristallstruktur erhalten. Die Umwandlung des Kristallgitters von Calciumsulfat-Dihydrat in Calciumsulfat-Anhydrit II vollzieht sich dabei direkt durch Mineralneubildung. Diese Umwandlung wird zu einem Verfahren entwickelt und als `Quasitrockenes Saeure-Anydrit-Verfahren` bezeichnet. Die Reaktion und ihr Mechanismus wurde zuerst in Laborversuchen untersucht. Als Ausgangsstoff ist jedes feinteilige Calciumsulfat-Dihydrat geeignet. Der bereits im Kraftwerk feinteilig-kristallin erzeugte REA-Gips mit 10% Restfeuchte ist besonders vorteilhaft, da er fuer diese Verwendung vorher nicht getrocknet und nicht gemahlen werden muss. Die Verfahrensentwicklung wurde bis in den halbtechnischen Massstab durchgefuehrt und Auslegungsgrundlagen fuer Grossanlagen an Kraftwerksstandorten erarbeitet. Als Reaktionsaggregat zeigte sich der direkt beheizte Drehrohrofen geeignet. Der REA-Anhydrit wird in diesem Verfahren als trockenes feinteiliges Produkt mit reproduzierbaren Teilchengroessen um 2 Mikron erhalten und besitzt neuartige technologische Eigenschaften. Seine Verwendungsmoeglichkeit wurde fuer die Zementindustrie sowie als Rohstoff zur Herstellung von Fuellstoffen untersucht. Fuer die Zementindustrie ist er grundsaetzlich geeignet. Der Einsatz als Fuellstoff ermoeglicht eine erweiterte Verwendung des REA-Gipses ausserhalb der traditionellen Bereiche der Gipsindustrie. Erste Versuche erlauben die Schlussfolgerung, dass der REA-Anhydrit nach einer Aufbereitung, die ebenfalls labormaessig neu entwickelt wurde, die fuer einen hochwertigen Fuellstoff notwendigen guten Eigenschaftsmerkmale hat.

    Two examples are chosen to describe the possiblities and limitations of using 3D seismic data for the interpretation of structures and the seismic characterisation of reservoirs. New techniques of seismic classification offer a great deal of possibilities, especially if - as in the case of Ruehme - there is a sufficiency of data from many borehole locations which enables the training of algorithms.(orig.) [Deutsch] Anhand zweier Beispiele wurden die Moeglichkeiten aber auch die Grenzen des Einsatzes 3D seismischer Daten bei der strukturellen Interpretation und der seismischen Reservoircharakterisierung aufgezeigt. Neuartige Techniken der seismischen Klassifizierung erweitern die Moeglichkeiten dabei betraechtlich, insbesondere, wenn - wie beim Beispiel Ruehme - durch die vielen Bohrlokationen ausreichend Daten zum Trainieren der Algorithmen zur Verfuegung stehen.

    -N-Rueckbelastungen in die KA um etwa 70% reduziert, waehrend sich die N-Frachten im entwaesserten Klaerschlamm um etwa 45% vermindern. Die Trockensubstanzgehalte im Klaerschlamm werden durch weiteren Abbau organischer Verbindungen um 20...25% reduziert. Dies kommt einer aequivalenten Mengenreduzierung des entwaesserten Klaerschlammes gleich. Die Entwaesserungseigenschaften des Schlammes werden deutlich verbessert. Vor allem die erhoehte Trennschaerfe und somit die verbesserte Schlammwasserqualitaet bedeutet im praktischen Einsatz eine Einsparung an Betriebskosten fuer Chemikalien (z.B. Polyelektrolyt). Tests in der Kammerfilterpresse und Flockungstest zeigten ebenfalls verbesserte Entwaesserungseigenschaften. Weiterhin ist festzustellen: Die Moeglichkeit der Faulzeitverkuerzung (ca. 15 d) bringt weitere Einsparpotentiale im Bereich der Schlammfaulung. Die zusaetzliche Rueckbelastungsreduzierung in Bezug auf P und schwer abbaubaren CSB entlastet die KA. Die Kombination mit der Klaerschlammdesintegration kommt vor allem bei sehr kurzen Faulzeiten (ca. 10 d) zum Tragen. Die Erprobung des Verfahrens fuer simultan aerob stabilisierte Schlaemme fuehrte, auch in Kombination mit der Klaerschlammdesintegration, nur zu Stickstoffreduzierungen von bis zu 15% und blieb damit unter den Erwartungen. Insgesamt laesst sich feststellen, dass das Projekt inhaltlich erfolgreich abgeschlossen wurde, dass die Ergebnisse in Bezug auf die Hauptzielrichtungen ausserordentlich positiv ausfielen und das der vorgesehene Kostenrahmen eingehalten wurde. Die Reduzierung der Stickstoffgehalte wird in absehbarer Zeit vorrangig der landschaftsbaulichen Verwertung zugute kommen. Insbesondere die Kombination der genannten Effekte macht das Verfahren fuer die praktische Anwendung interessant. (orig.)

[German] Schwerpunkt dieser Arbeit war die Verfahrensentwicklung zur Ultraspurenbestimmung der PGE in Umwelt- und geologischen Proben unter Verwendung der massenspektrometrischen Isotopenverduennungsanalyse mit anschliessender Bestimmung an einem Quadrupol ICP-MS (ICP-QMSIVA). Das in dieser Arbeit entwickelte Verfahren zur Ultraspurenbestimmung der PGE mit ICPQMSIVA wurde im Rahmen des Projektes ''Production and certification of a road dust reference material for platinum, palladium and rhodium (PGEs) in automative catalytic converters (PACEPAC)'' der Europaeischen Union zur Zertifizierung von zwei Referenzmaterialien fuer Umweltproben eingesetzt. Hierbei wurde in der Vorrunde der Zertifizierung (''intercomparison round'') eine sehr gute Uebereinstimmung der Ergebnisse mit dem gewichteten Mittelwert der Ergebnisse fuer Pd und Pt mit den uebrigen teilnehmenden Laboratorien festgestellt. Die mit der hier entwickelten Methode erhaltenen Ergebnisse wurden ohne Ausnahme fuer alle gemessenen Elemente zur vorlaeufigen Zertifizierung herangezogen. Damit leistete die vorliegende Arbeit einen erheblichen Beitrag zum erfolgreichen Abschluss dieses Projekts. Den Erwartungen hinsichtlich Richtigkeit und Reproduzierbarkeit des entwickelten Verfahrens wurde somit voll entsprochen. Erneut konnte die grosse Bedeutung der Isotopenverduennungstechnik fuer die Zertifizierung von Referenzmaterialien aufgezeigt werden, da mit dieser Technik bei sachgerechtem Einsatz Ergebnisse hoher Richtigkeit erzielt werden. Durch vergleichende Messungen mit der NiS-Dokimasie und NAA, die in einer Kooperation mit dem Kernchemischen Institut der Universitaet Mainz durchgefuehrt wurden, und dem hier verwendeten Verfahren, konnten uebereinstimmende Daten, hinsichtlich der Abnahme der Konzentrationen von Pd und Pt in Abhaengigkeit von der Entfernung zu einer Autobahn, erzielt werden.

    By means of the ETVS process, predominantly liquid organic residues can be converted into electrical energy and mineral ash decentrally, i.e. where they accrue. The process is exemplified with reference to sewage sludge. Sludge containing at least about 4 % dry residue is dewatered to the highest dry substance content possible. The obtained filter cakes are indirectly dried in a fluidized-bed drier using internal process waste heat. Then the organic sewage sludge constituents are gasified in an atmospheric fluidized bed system. The cleaned product gas is used to generate power in a cogeneration power plant, meeting the sewage treatment plant's in-house power demand. The ETVS process is self-sufficient in terms of thermal energy requirement from an initial dry substance content of the filter cake > 40 %. Incineration is a means of disposing of sewage sludge in accordance with the boundary conditions for sewage sludge disposal from 2005, laid down in the technical code on municipal waste. Combining the ETVS process with modern biological treatment stages makes for a substantial cut in the construction and operating cost of sewage treatment plants. (orig.)

    Directionally solidified turbine blades for high-temperature applications today are commonly produced by the Bridgman casting process. The production of a newly constructed turbine blade requires a number of costly and time-consuming casting experiments. The author develops a numerical simulation model based on the finite element method and net radiation method for low-cost and short-term simulation and optimisation of the casting experiments. Several different numerical methods for calculating thermal radiation are compared (radiosity, ray tracing and the finite difference method), and the simulation results are presented for several exemplry turbine blades. Further, an optimisation strategy for improving the quality of the turbine blade casting process is presented. (orig.). 65 figs., 8 tabs.

    The following paper demonstrates, how a geostatistical approach can help interpolating hydrogeological parameters over a certain area. The basic elements developed by G. Matheron in the sixties are represented as the preconditions and assumptions, which provide the best results of the estimation. The variogram as the most important tool in geostatistics offers the opportunity to describe the correlating behaviour of a regionalized variable. Some kriging procedures are briefly introduced, which provide under varying circumstances estimating of non-measured values with the theoretical variogram-model. In the Ronneburg mine district 108 screened drill-holes could provide coefficients of hydraulic conductivity. These were interpolated with ordinary kriging over the whole investigation area. An error calculation was performed, which could prove the accuracy of the estimation. Short prospects point out some difficulties handling with geostatistic procedures and make suggestions for further investigations. (orig.) [Deutsch] Der folgende Artikel soll aufzeigen, inwiefern ein geostatistischer Ansatz hilfreich ist, um hydrogeologische Parameter flaechenhaft zu interpolieren. Dabei werden die von Matheron in den sechziger Jahren entwickelten Grundlagen vorgestellt und die Voraussetzungen definiert, unter denen die geostatistischen Schaetzmethoden die besten Ergebnisse liefern. Das Variogramm, als wichtigstes Werkzeug, bietet die Moeglichkeit, die raeumliche Korrelation der untersuchten Variable zu belegen. Mehrere Kriging-Verfahren werden skizzenhaft vorgestellt, die es unter unterschiedlichen Voraussetzungen ermoeglichen, an den Stellen des Untersuchungsgebietes, wo keine Messungen vorliegen, Schaetzungen aus dem Variogramm-Modell zu errechnen. Im Ronneburger Bergbaugebiet wurden aus 108 verfilterten Bohrungen k{sub f}-Werte gewonnen, die mittels Ordinary Kriging flaechenhaft ueber das gesamte Untersuchungsgebiet interpoliert wurden.

    A finite vomume method for calculation of steady and unsteady flow on unstructured grids is parallelized by local spatial and time decomposition. In the first case, a parallel variant of the conjugated gradient method with multiple local preconditioning is formulated and analyzed. The method is tested for simple applications (e.g. flow around a cylinder). The second part of the publication describes a direct numerical simulation of turbulent flow around a sphere at a Reynolds number of 5000 (based on flow velocity and sphere diameter). Current and Reynolds-averaged flow fields are discussed. Particular emphasis is placed on coordinate-independent representation of the anisotropy ratios of the Reynolds tensor and dissipation tensor. (orig.) [Deutsch] Ein Finite-Volumen-Verfahren fuer die Berechnung stationaerer und instationaerer Stroemungen auf unstrukturierten Netzen wird durch Gebietszerlegung im Raum und Zeit parallelisiert. Fuer die raeumliche Zerlegung wird eine parallele Variante der konjugierten Gradienten Methode mit mehrfacher, lokaler Vorkonditionierung formuliert und analysiert. Anhand einfacher Anwendungsbeispiele (Zylinderumstroemung, deckelgetriebene Nischenstroemung) wird das entwickelte Gesamtverfahren getestet und seine Effizienz bestimmt. Der zweite Teil der Arbeit beschreibt eine direkte numerische Simulation der turbulenten Kugelumstroemung bei einer Reynolds-Zahl von 5 000 (basierend auf Anstroemgeschwindigkeit und Kugeldurchmesser). In der Ergebnisauswertung werden augenblickliche und Reynolds-gemittelte Stroemungsfelder diskutiert und besonderer Wert auf eine koordinatenunabhaengige Darstellung der Anisotropieverhaeltnisse des Reynolds-Tensors und des Dissipationstensors gelegt.

    initiation tests were run. Accompanying batch-tests and micro-biological analyses served mainly for the kinetic examination of the metabolisms, that is for the determination of the conversion performances and for the basic analysis of the relevant metabolism ways and the participating micro-organisms. (orig.) [German] Die Stickstoffelimination in kommunalen und industriellen Abwaessern spielt in der Abwasserreinigung weiterhin eine bedeutende Rolle, zumal mit der Abwasserverordnung (AbwV) von 1997 einige Veraenderungen bei den Anforderungen und Regelungen hinsichtlich der Schad- und Naehrstoffentfernung vorgenommen wurden. Da gerade die Stickstoffentfernung oftmals einen erheblichen Kostenfaktor bei der Abwasserreinigung darstellt, insbesondere wenn es um die (Mit-)Behandlung hoch stickstoffbelasteter Teilstroeme geht, ist man stetig auf der Suche nach wirtschaftlichen Behandlungskonzepten. Im Rahmen des Forschungsvorhabens wurde das Verfahren der Deammonifikation entwickelt, d.h. die Prozessfolge aus aerober Nitritation und anoxischer Ammoniumoxidation ('biologische Komproportionierung' von Ammonium und Nitrit zu molekularem Stickstoff), die komplett auf den Stoffwechselprozessen autotropher Mikroorganismen beruht, wodurch sich vor allem Einsparpotentiale hinsichtlich des Kohlenstoffbedarfes ergeben. Aufgrund des verkuerzten aeroben Oxidationsschrittes und bei Anwendung der Biofilmtechnologie lassen sich zudem Sauerstoffbedarf und Reaktionsvolumen reduzieren. Im Hinblick auf einen gezielten verfahrenstechnischen Einsatz der Deammonifikation waren im Rahmen der Forschungsarbeiten die prozessbestimmenden Einflussgroessen zu bestimmen und geeignete Verfahrenstechniken und Verfahrensfuehrungen naeher zu ueberpruefen. Hierzu wurden ausgehend von gross- und pilottechnischen Untersuchungen und Erkenntnissen unter Beruecksichtigung (mikro-)biologischer Zusammenhaenge die wesentlichen Randbedingungen zur Realisierung sowie das Betriebsverhalten der autotrophen

    Detecting thin layers of chemicals covering the sea bottom with existing techniques is not feasible. Scanning an area for possible polluted sea bottom eg. with SONAR-based acoustical measurements requires a pointwise operation. The acoustical measurement technique proposed here scans the sediment surface and allows for the qualitative contamination estimation for distances up to approx. 100 m away from the sensor. Experiments in the laboratory as well as field experiments have been undertaken, where a comparable but riskless contamination method was used. Both scenarios show the same change in the acoustical transmission when thin layers of pollutants cover the sediment. A numerical verification of the observed effects was done. The prototype of the detector system consists of a autonomous acoustical transponder to be deployed separately from the acoustical sensor equipped with an array of hydrophones that can be mounted on a ROV (remotely operated vehicle). Newly developed hydrophones provide an optimalized shielding of ambient noise. The system was designed for a mobile operation on board a ship. A stationary operation eg. in endangered harbor areas or rivers is possible, where a permanent supervision of the sediment layer is required. The necessary modification of the sensor system for this task can be done without additional development. (orig.)

    The RCP method was designed as a residue-optimised alternative to the thermally optimised grate firing of residual wastes. Its technical realisation and development to market maturity took no more than 5 years. In the first process stage the waste is converted to high-carbon pyrolysis charcoal and high-rank gas in the absence of oxygen. In the second stage these substances are oxidised by addition of oxygen. The resulting temperature causes the non-combustible constituents of the slag to melt. In a third, optional, stage this molten slag can be liberated of (heavy) metals to such an extent that it can subsequently be used directly as additive for grinding. Further exhaust gas treatment is facilitated by the use of a circulatory fluidised-bed secondary combustion chamber. Despite the reduced flue gas volume and resultant higher pollutant concentrations in the crude gas, overall emissions are lower than in conventional plants. [Deutsch] Das reststoffoptimierte RCP Verfahren ist als Alternative zur thermisch optimierten Rostverbrennung von Restabfaellen konzipiert. In nur fuenf Jahren wurde das Verfahren technisch umgesetzt und zur Marktreife entwickelt. In einer ersten Stufe des Verfahrens wird der Abfall unter Luftabschluss in einen kohlenstoffreichen Pyrolysekoks und eine heizwertreiches Gas umgesetzt. Im zweiten Schritt werden diese Stoffe unter Zugabe von Sauerstoff oxidiert. Dabei treten Temperaturen auf, bei denen die nichtbrennbaren Bestandteile der Schlacke schmelzen. Optional wird diese Schmelzschlacke in einem dritten Schritt derart von (Schwer-) Metallen befreit, dass sie anschliessend direkt als Zement-Zumahlstoff eingesetzt werden kann. Die Nutzung der zirkulierenden Wirbelschicht - Nachbrennkammer zur Abgasbehandlung vereinfacht die weitergehende Abgasbehandlung. Trotz verringertem Rauchgasvolumen und damit hoeheren Schadstoffkonzentrationen im Rohgas werden die Gesamtemissionen gegenueber konventionellen Anlagen verringert. (orig./SR)

    Full Text Available Im vorliegenden Beitrag wird der Frage nachgegangen, welche Merkmale ein Verfahren zur Feststellung des Sprachstandes im Bereich Erzählkompetenz vereinen sollte, um nutzbare Informationen für die Planung an-schließender Fördermaßnahmen zu liefern. Dabei wird von der spracherwerbstheoretisch hergeleiteten Annahme ausgegangen, dass Förderangebote entwicklungssensitiv angelegt sein sollten, also von der erwartbaren Erwerbsprogression und dem jeweiligen Sprachstand des Kindes ausgehen sollten. Mit dieser diagnostischen Zielsetzung vor Augen werden anhand der Kategorien „entwicklungspsychologische/schulische Relevanz“, „profilanalytische Auswertung“ sowie „Authentizität der Sprachdaten“ Anforderungen an ein förderdiagnostisches Verfahren formuliert und exemplarisch auf Erkenntnisse der Spracherwerbsforschung zurückbezogen. The present article addresses the question of which characteristics a language proficiency assessment of children ́s narrative competence should possess to allow for its results to be used for planning subsequent assistance measures.The underlying assumption states that language acquisition processes follow their own inherent developmental pathway. Language promotion programmes should therefore be responsive to the children's development and be based on the respective proficiency level and the learning progress that may be expected. In view of this objective, the article specifies requirements on „interventional diagnostics” and correlates these with insights from languageacquisition research.

    Full Text Available Osteoporotische Wirbelbrüche sind häufig. Der Großteil ist gutartig mit einem selbstlimitierenden Verlauf. Allerdings sehen wir in der Wirbelsäulenchirurgie zunehmend auch die Problemfälle: persistierende Instabilität/ Pseudarthrose nach einer Fraktur, der langsam progressive Verlust der Haltung/Wirbelsäulenbalance als Folge mehrerer Wirbelbrüche und schließlich neurologische Komplikationen in Verbindung mit einer osteoporotischen Fraktur. Die Injektion von Knochenzement zur Stabilisierung von Wirbelfrakturen ist effizient und hat sich bewährt. Damit erreicht man eine Stabilisierung des Wirbels und eine sehr wirksame Schmerzkontrolle. Zusätzlich (und häufig zu wenig beachtet können damit ein weiteres Einsintern des Knochens verhindert und Folgekomplikationen so vermieden werden. Wo diese einfache minimalinvasive Technik nicht mehr genügt, sind offene Verfahren notwendig. Auch dabei wird eine kombinierte Technik angewendet: Die Stabilisierung erfolgt nach den gängigen wirbelsäulenchirurgischen Prinzipien, zur Verankerung der Implantate im osteoporotischen Knochen wird ebenfalls Knochenzement verwendet.

  2. Making humor together: phenomenology and interracial humor

    Directory of Open Access Journals (Sweden)

    Michael D. Barber

    2016-01-01

    Full Text Available This paper explains humor through phenomenological concepts and methods. The three major theories of humor: Superiority, Relief, and Incongruity depend on the thwarting of intentional expectations. Since one experiences an incongruity between what is intended and what is actually experienced, the incongruity theory affords the best explanation, but intentionality remains fundamental for all theories. Theorists of humor rightly insist that the enjoyment of humorous incongruity completes the definition of humor, but such enjoyment also depends on a special epoché, usually elicited by the cues of an interlocutor who invites the listener to leap together into the humorous finite province of meaning. In this province, actions and statements, hurtful in everyday life, such as a pie thrown at someone who ducks as the pie hits another, produce laughter. This comic epoché resembles the phenomenological epoché in its distancing from everyday life, and, like the phenomenological epoché, it opens everyday experience to reflection. Although one often experiences and enjoys humor alone, humor is thoroughly intersubjective and more frequently occurs when two persons participate in the humorous epoché together. The opportunities for making humor together are enhanced to the extent the partners differ in their expectations and responses to situations. Those differences, including bodily differences, often result from the complex intersubjective networks, including culture. As in the case of a seemingly solitary activity like reflection, which one learns from others and exercises on one’s own autonomously, one internalizes others’ styles of humor and discovers such internalization through reflection on one’s «because motives». On the basis of these features – intentionality, epoché, and intersubjectivity, the paper concludes by briefly examining an example of interracial humor. Despite the racist character of much interracial humor, the example

    To classify a liver tumor, image-guided percutaneous biopsy of a liver lesion is indicated. Using ultrasound (US) to guide a biopsy needle into a liver lesion has been proven useful and safe. If a lesion cannot be seen on US or the access to a lesion has been complicated by its position, CT-guided biopsy can be performed. If a lesion cannot be delineated on US or CT, MR-guided biopsy is recommended. Using hepatospecific contrast agents, the time span to delineate tumor tissue can be prolonged. To differentiate diffuse liver disease, transvenous biopsy under fluoroscopic control can be performed if a percutaneous biopsy is contraindicated. In recent years fine-needle aspiration biopsy has been increasingly replaced by coaxial 14-20 G core biopsy, which is a safe and efficient technique to classify liver lesions and has a low complication rate. (orig.) [German] Zur definitiven Klaerung der Dignitaet und Tumorklasse einer Leberlaesion ist eine bildgesteuerte perkutane Biopsie indiziert. Unter Verwendung der Sonographie ist das Verfahren treffsicher und einfach. Die computertomographiegezielte Biopsie ist wegen der ueberlagerungsfreien, reproduzierbaren Darstellung von Leberherden und ihren Nachbarstrukturen in vielen Faellen besser geeignet. Fuer Laesionen, die sich weder mit Ultraschall noch mit CT biopsieren lassen, bietet sich die Magnetresonanztomographie an. Durch den Einsatz leberspezifischer Kontrastmittel kann das Zeitfenster zur Durchfuehrung einer Biopsie verlaengert werden. Zur Abklaerung diffuser Lebererkrankungen wird bei kontraindizierter perkutaner Biopsie eine transvenoese Leberbiopsie unter Durchleuchtung empfohlen. Die in den 1980er Jahren propagierte Feinnadelaspirationsbiopsie wurde zunehmend durch Stanzbiopsien (Durchmesser 14-20 gg) in koaxialer Technik ersetzt, da diese eine zuverlaessige artdiagnostische Klassifikation bei niedriger Komplikationsrate ermoeglichen.

    Spiral CT currently is the modality of choice for all aspects of diagnostic evaluation of the liver. Optimal selection of treatment should be based inter alia on the findings obtained by spiral CT with arterial application of contrast medium, as for example S-CTA (primary liver tumors), or S-CTAP (secondary liver tumors). Ultrasonography is the major supplementing modality. In the near future, MR imaging applying liver-specific contrast-enhancing agents is expected to become an important competing technique, and further developments of interest in diagnostic imaging of the liver are in the offing: it is not yet known which technique will be the modality of choice at the onset of the 21st century. (orig.) [Deutsch] Die Spiral-CT ist zur Zeit das empfehlenswerte Verfahren fuer alle Fragen der Leberdiagnostik. Zur optimalen praetherapeutischen Beurteilung der Leber sollte die Spiral-CT mit arterieller Kontrastmittelapplikation als S-CTA (primaere Lebertumoren) bzw. S-CTAP (sekundaere Lebertumoren) durchgefuehrt werden. Der US kommt ein Stellenwert als ergaenzende Methode zu. In Zukunft wird die MRT mit leberspezifischen Kontrastmitteln ein konkurrierendes Verfahren zur Spiral-CT darstellen, wobei eine weitere interessante Entwicklung auf dem Gebiet der hepatischen Bildgebung zu erwarten ist: Das diagnostische Verfahren der Wahl fuer die Leber zu Beginn des 21. Jahrhunderts ist noch nicht definiert. (orig.)

    A new technology for fast, large-surface deposition of high-quality semiconducting thin films for PV systems. The new technology, CSVT (close-space vapour transport), is based on a combination of VPE (vapour phase epitaxy) in open systems and CVT (chemical vapour phase transport) in closed systems. The two-source CVD experiments with two different transport gases, i.e. Cu{sub 2}Se with iodine and Ga{sub 2}Se{sub 3} with HCl, enabled controlled variation of the Cu:Ga ratio in the gaseous phase. The solar cells produced had efficiencies of more than 4%. The best solar cell produced had an efficiency of 4.8% and an open terminal voltage of 863 mV.

    The impact-echo method is based on the use of elastic waves. It was developed in the 1980 for the testing of concrete structures and is currently widespread. Main application areas are the component and coating thickness measurement and detection of delaminations, voids and other defects. Specifically, the method is also used to check the injection faults of clamping channels. Another application is the determination of mechanical material parameters such as the modulus of elasticity. Since the original development of the method has undergone several enhancements. The conversion of a single-point measurement method towards a area component testing, the use by the optimized measurement data acquisition and evaluation enlarged and delivered an important prerequisite for increasing the efficiency. The use of air-coupled sensors not only increases the measurement speed but also provides advantages in rough component surfaces. The imaging analysis in conjunction with signal processing algorithms simplifies the interpretation and allows statistical evaluation. [German] Das Impact-Echo-Verfahren beruht auf der Nutzung elastischer Wellen. Es wurde in den 1980er Jahren fuer die Pruefung von Stahlbetonbauteilen entwickelt und ist derzeit weit verbreitet. Haupteinsatzgebiete sind die Bauteil- und Schichtdickenmessung sowie die Detektion von Delaminationen, Hohl- und anderen Fehlstellen. Insbesondere wird das Verfahren auch zur Pruefung des Verpresszustandes von Spannkanaelen herangezogen. Eine weitere Anwendung ist die Bestimmung mechanischer Materialparameter wie dem Elastizitaetsmodul. Seit der urspruenglichen Entwicklung hat das Verfahren verschiedene Weiterentwicklungen erfahren. Die Ueberfuehrung von einem Einzelpunktmessverfahren hin zu einer flaechigen Bauteilpruefung hat die Einsatzmoeglichkeiten durch die optimierte Messdatenaufnahme und -auswertung vergroessert und eine wichtige Voraussetzung zur Erhoehung der Leistungsfaehigkeit geliefert.

    Owing to the intensification of treatment processes and the construction of new sewage plants sewage arisings are due to rise considerably. The thermal treatment of sewage sludge which it has not been possible to avoid or utilise is an important and indispensable part of any sewage sludge disposal concept. If equipped with a state-of-the-art flue gas purification process that uses carbonaceous adsorbents (Sorbalit trademark), thermal treatment of sewage sludge can be regarded as an environmentally safe process technique. [Deutsch] Die anfallenden Klaerschlammengen werden durch die Intensivierung der Klaerprozesse und der Bau neuer Klaeranlagen deutlich zunehmen. Die thermische Behandlung nicht vermiedener oder verwerteter Klaerschlaemme stellt einen bedeutenden und unverzichtbaren Teil der Klaerschlamm-Entsorgungskonzepte dar. Bei Installation einer - dem Stand der Technik - entsprechenden Rauchgasreinigung mit dem Einsatz kohlenstoffhaltiger Adsorbentien (Sorbalit {sup trademark}) ist die thermische Behandlung von Klaerschlamm eine umweltsichere Verfahrenstechnik.

    Linneborn, J

    1987-05-21

    The invention refers to a process for the gasification of solid and combustible material in a moving bed and a unit in which this process can be carried out. By material to be gasified one means small material such as ground fossil coal and all organic substances such as wood, straw, husks and shells of fruit, to which sewage sludge can be added. The new process can be carried out, according to the invention, in a closed duct moved by vibration or shaking, in which the material or the ash produced moves from one end to the other by suitable vibration and comes into contact with round heat sources largely resistant to friction. This achieves rapid gasification of the material (at about 1000/sup 0/C) by convection and radiation.

    The use of salt hydrate melting in the loading process is not favourable from the technical and energy point of view. According to the invention, a saturated solution is filled into the store at the required phase conversion point. This can be done by neutralization (e.g. a reaction between H/sub 3/PO/sub 4//NAOH/H/sub 2/O in the mol ratio of 1/2/10 gives Na/sub 2/HPO/sub 4/.12H/sub 2/O corresponding to Na/sub 2/SO/sub 4/.10H/sub 2/O), or by conversion of acid/basic salts with bases/acids respectively (e.g. Na/sub 3/PO/sub 4//H/sub 3/PO/sub 4//H/sub 2/O in the ratio 2/1/36 to Na/sub 2/HPO/sub 4/.12H/sub 2/O, analogous to K/sub 3/PO/sub 4/.7H/sub 2/O, KF.4H/sub 2/O or CaCl/sub 2/.6H/sub 2/O). During the process one must ensure accurate dosing and good mixing. A saturated solution is also available by dissolving salts free of water/or with little water in appropriate quantities of water below the melting point of the required hydrate. Such systems are used where the phase change heat exceeds the heat capacity of the water at this temperature and the hydrates should contain at least three crystal water molecules more than the nearest hydrate.

    1984-01-12

    The invention refers to a process for producing synthetic ammonia gas from gases containing hydrocarbons, which is reformed catalytically and autothermally with a synthesis gas containing oxygen and then subjected to conversion to synthesis gas containing carbon dioxide and hydrogen. In order to simplify the plant required for such a process, the invention provides that part of the gas main flow is subjected to a multistage alternating pressure absorption plant (PSA plant) in a bypass of the gas main flow and the separated hydrogen is returned to the remaining gas main flow, in order to set the required H/sub 2/N/sub 2/ ratio and that the fission gas is subject to carbon dioxide washing and methanizing after conversion. This process therefore does not need a pipe splitting furnace and enrichment of the air with oxygen.

    Parrafins, olefines or alkyl aromatic compounds can be dehydrated using a catalyst with a molybdenum oxide compound as the active component and magnesium oxide and crystalline clay or titanium oxide or aluminium oxide as carrier. Monoolefines are formed, which are returned to the contact area, and diolefines. The oxygen of the catalyst is used up in the process, so that this has to be regenerated by a gas rich in oxygen at intervals. In order to avoid oxidation cracking by the oxygen, the catalyst must be flushed with an inert gas before reuse. Dehydration occurs in a fluidised bed, where the yield of olefines is increased by dilution of the hydrocarbons by an inert gas.

    Separators of such cells must be resistant to corrosion and insensitive to cyclical changes of volume. Appropriate materials (e.g. BeO, ThO/sub 2/, Si/sub 3/N/sub 4/) are however not ion-conducting, and must therefore be used with an open structure. In well-known ceramic separators, the space between the electrodes has small separator material poured into it, and this causes variations in porosity and density; also the cells are loaded by the necessary shaking and vibration. The process of the invention consists of mixing the finely divided separator material and/or the electrodes with electrolyte powder and a plastic which is completely decomposed by heat. The mixture is rolled into a flat plate, and this is fitted in the cell individually or as a compound electrode/separator plate. After assembly, the whole cell is heated above the decomposition temperature of the plastic. A solution of polyisobutylene in cyclohexane is preferred, where the proportion is 2-5%. The separator material is used with two grain sizes, large particles of 2 mm diameter (40-80%) and fine particles in the range 5-60 ..mu..m (60-20%).

    According to the invention gypsum from flue gas wet desulfurization is dried without loss of crystallization water by a 1-4% sidestream of the flue gas in a suspended bed dryer and is subsequently separated in a cyclone. The sidestream is removed after the electrostatic precipitator, where the gas temperature is 100-130 degrees, and returned to the main gas stream prior to desulfurization, thus preventing the dehydration of the gypsum and eliminating the energy costs of reheating the gas stream to prevent acid condensation.

    Benign pancreatic tumors should undergo surgical resection when they are symptomatic or - in the case of incidental discovery - bear malignant potential. This is the case for the majority of benign pancreatic tumors, especially for intraductal papillary mucinous neoplasms or mucinous cystic adenomas. In addition, resection is indicated for all tumors where preoperative diagnostic fails to provide an exact classification. Several different operative techniques are available. The treatment of choice depends on the localization of the tumor, its size and on whether there is evidence of malignant transformation. Partial duodenopancreatectomy is the oncological treatment of choice for tumors of the pancreatic head whereas for tumors of the pancreatic tail a left-sided pancreatectomy is appropriate. Middle pancreatectomy or duodenum-preserving resection of the pancreatic head is not a radical oncologic procedure. They should only be performed in cases of tumors without malignant potential. (orig.) [German] Die Indikationsstellung zur Resektion benigner Pankreastumoren ist gegeben, wenn es sich um einen symptomatischen Tumor handelt oder - bei einem Zufallsbefund - um einen Tumor mit Potenzial zur malignen Entartung. Dies besteht bei der Mehrzahl der benignen Pankreastumoren, insbesondere bei der intraduktalen papillaeren muzinoesen Neoplasie (IPMN) oder muzinoesen Zystadenomen. Operativer Abklaerung beduerfen auch Tumoren, die unter Ausschoepfung aller diagnostischer Moeglichkeiten nicht eindeutig klassifizierbar sind. An chirurgischen Therapieverfahren stehen verschiedene Techniken zur Verfuegung. Die Wahl des Verfahren haengt von der Groesse und Lokalisation des Tumors ab und von der Frage, ob eine maligne Entartung bereits stattgefunden hat. Das onkologisch korrekte Standardresektionsverfahren bei Tumoren des Pankreaskopfes ist die partielle Duodenopankreatektomie, bei Tumoren des Pankreasschwanzes die Pankreaslinksresektion.

    The oft-quoted aphorism that "laughter is the best medicine" is examined. Specifically, three big drops in the shower of claims regarding the benefits of humor in treating physical and mental disorders are evaluated. First, studies of the effects of mirth and laughter on the physiology of the body reveal both good and bad news. The meager evidence of the salutary effects of positive emotions on the cardiovascular, respiratory, immune and neuroendocrine systems, though apparently supportable on more or less scientific, rational and subjective grounds, needs much better verification from more extensive, replicable, and empirical research. Second, despite numerous claims, in the context of behavioral or psychosomatic medicine, that a joyful, optimistic, or humorous attitude can render a salubrious effect, almost to the extent of preventing illness and curing physical disease, the jury is still out and issuing dire warnings regarding too ready acceptance of this largely anecdotal evidence. Much careful "clinical trial" research needs to be mounted to determine the conditions under which humor works best, if at all. The type of patient, the kind of humor, the type and severity of illness, the psychosocial contexts-all of these factors should be considered. Third, the infusion of humor into psychotherapy is great news for some therapists and awful news for others. A number of more balanced approaches point up the probability that when mirth is incorporated into therapy judiciously, appropriately, and meaningfully it can be of value.

    The electromagnetic and ultrasonic techniques are comparably recent NDT methods for determination of stress states of components. They are simple in application, but require pre-measurement preparation: Electromagnetic techniques need calibration, and quantitative stress analysis by ultrasonic techniques needs reference values, i.e. verified materials-specific quantities to be obtained with representative specimens. Electromagnetic and ultrasonic techniques have been developed for specific tests at defined components, and the corresponding instruments and sensors have been used in practice for several years now. The paper summarizes fundamental aspects and explains the state of the art by means of several examples.

    The invention concerns a process for charging batteries and a circuit for carrying out the process. First, in a test routine, the battery temperature, the correct polarity of the battery and the actual state of battery charge are measured and the number of cells is determined from the battery no-load voltage. If this falls below the reference no-load voltage, the charging current is repeatedly switched on for a predetermined period of time, and the battery voltage is measured. If an equilibrium voltage predetermined by heating of the battery cells is determined, the battery is charged for a predetermined period of time, until the charged capacity has reached the nominal capacity. Then a maintenance charge to maintain the batter capacity is provided at a time space after the charge.

  8. Ein kombinierter Operationsansatz zur Therapie der rektovaginalen Endometriose auf der Basis histologischer Befunde

    Directory of Open Access Journals (Sweden)

    Köhler C

    2008-01-01

    Full Text Available Einleitung: Eine Endometriose des Septum rectovaginale kann oberflächlich dem Darm aufliegen oder die Darmwand infiltrieren. Durch bildgebende Verfahren kann jedoch präoperativ eine Infiltration des Darms weder hinreichend bestätigt noch ausgeschlossen werden, was zu einem therapeutischen Dilemma führt, da nur die Darmwand eindeutig infiltrierende Endometrioseprozesse durch eine Darmresektion behandelt werden sollten. Wir möchten ein neues Operationsverfahren vorstellen, das eine intraoperative Differenzierung zwischen einer oberflächlichen und einer infiltrativen Darmendometriose erlaubt. Patienten und Methodik: 70 Patientinnen mit rektovaginaler Endometriose wurden nach einem neu entwickelten kombinierten vaginal-laparoskopisch-abdominalen Verfahren operiert. Diese Operationsmethode wird Schritt für Schritt vorgestellt. Die Entscheidung zur Darmresektion wurde dabei allein aufgrund der intraoperativen Befunde und nicht aufgrund der präoperativen bildgebenden Diagnostik getroffen. Alle Resektate wurden standardisiert histologisch aufgearbeitet. Ergebnisse: Ob eine Darmresektion notwendig war, ließ sich intraoperativ anhand der Präparation des rektovaginalen Septums entscheiden. Daher wurden nur bei Patientinnen mit gesichertem infiltrativem Darmbefall Darmresektionen unter Erhalt des Mesointestinums durchgeführt. Weder intraoperative noch postoperative Komplikationen wie Anastomoseninsuffizienzen oder Restharnmengen traten auf. Diskussion: Die vorgestellte Operationsmethode zur Therapie der rektovaginalen Endometriose erlaubt eine exakte Diagnosestellung und präzise Therapieentscheidung bei minimaler Morbidität. Die Resektion des Darmschlauches ohne Mesoresektion ist ausreichend, da sich die Endometrioseknoten – wie histologisch bewiesen wurde – nur im ventralen Darmbereich befinden. Durch die Mesoerhaltung werden die vegetativen Funktionen des kleinen Beckens nicht beeinträchtigt.

    The methodology introduced in this article is capable of describing a binary behavior of distributed discrete event systems. This is the basis for a safety analysis in early phases of system development and for an automated determination of failure dependencies. For this purpose a system equation similar to the state-space representation in system theory is used. The equation is evaluated applying the Max-Plus/Min-Plus algebra. The procedure is exemplified by a simplified braking system. (orig.) [German] In dem vorliegenden Artikel wird ein Verfahren zur binaeren Beschreibung von verteilten ereignisdiskreten Systemen vorgestellt. Dieses wird als Grundlage fuer eine Sicherheitsanalyse in einer fruehen Phase der Systementwicklung und zur automatisierten Ermittlung von Fehlerabhaengigkeiten eingesetzt. Hierzu wird eine Systemgleichung verwendet, die aehnlich zu der Zustandsraumdarstellung der konventionellen Systemtheorie ist. Dabei erfolgt die Auswertung der Systemgleichung durch Anwendung der Max-Plus/Min-Plus Algebra. Die Vorgehensweise wird anhand des Beispiels eines vereinfachten Bremssystems erlaeutert. (orig.)

  12. Optimum control strategy for phosphate elimination; Optimale Steuerstrategie zur Phosphatelimination

    1997-12-31

    This study describes the most common phosphate elimination techniques. In the simplest cases, the chemicals are dosed according to previously established time curves. Nowadays, by contrast, dosage in proportion to quantity is largely preferred. Freight-proportional dosage will be more frequently employed in the future at plants for a population of more than 10000. Since investigations revealed that the results obtained using control systems are inferior to those obtained by means of automatic control systems, the latter are increasingly used. Even if PID control devices perform best, overshoot is not to be avoided with certainty because of the long dead time. According to the current state of knowledge, matched control and automatic control systems yield the best results. Further optimization can be achieved by driving them via a fuzzy-based system. (orig.) [Deutsch] In der vorliegenden Ausarbeitung wurden die gebraeuchlichsten Verfahren zur Phosphatelimination vorgestellt. In einfachsten Faellen wird die Dosierung nach festen Ganglinien vorgenommen. Sie wird heute weitgehend durch eine mengenproportionale Dosierung ersetzt. Frachtproportionale Dosierungen sind fuer Anlagen ueber 10.000 EW in Zukunft haeufiger zu finden. Nachdem die Untersuchungen gezeigt haben, dass Steuerungen nicht so gute Ergebnisse wie Reglungen ergaben, finden diese verstaerkt Anwendung. Auch wenn PID Regler das beste Ergebnis bringen, so kann mit Ihen wegen der langen Totzeiten ein Ueberschwingen nicht sicher vermieden werden. Nach heutiger Kenntnis erbringen aufeinander abgestimmte Steuer- und Reglungen die besten Ergebnisse. Werden sie ueber ein fuzzybasiertes System angesteuert, so ist eine weitere Optimierung gegeben.

    Colloidal solutions contain particles in the {mu}m range whose agglomeration and coagulation is of interest for certain applications. `Electrocoagulation` means that in an electric field droplets or particles in a disperse phase have higher kinetic energy so that the probability of overcoming repulsive forces and of forming bigger aggregates will increase. The electrocoagulation technique is applied for emulsion cracking of water-in-oil systems (desalination and dewatering of petroleum, petroleum cracking) and, in some cases, also for cracking oil-in-water systems. Removal of colloidal solids from aqueous solution during electrochemical waste water treatment is often carried out with the aid of dissolving aluminium or iron electrodes. The authors describe experiments in which the flow of an electric current, which would cause the electrodes to dissolve, was to be prevented. An alternating field was to induce oscillation of the particles, i.e. relative motion of the particles with respect to each other. (orig./SR) [Deutsch] Kolloidale Loesungen enthalten Partikel im {mu}m-Bereich. In manchen Bereichen ist deren Agglomeration bzw. Koagulation von Interesse. Unter dem Begriff der Elektrokoagulation versteht man im allgemeinen das Phaenomen, dass in einem elektrischen Feld Tropfen oder Partikel in einer dispersen Phase eine hoehere kinetische Energie besitzen, und dadurch die Wahrscheinlichkeit zur Ueberwindung von Abstossungskraeften und zur Bildung groesserer Aggregate steigt.

    Whenever advances in waste water treatment were achieved in the past they have spelt technically more sophisticated processes for the elimination of water-toxic products. At present, waste water treatment technology faces further demands. Apart from the issue of economy and the avoidance of excessive burdens to citizens, a question increasingly raised is whether waste water cleaning processes are themselves environment-friendly. Related studies are internationally known as Life Cycle Assessment (LCA). (orig.)

    Humor has neurophysiological effects influencing the release of cortisol, which may have a direct impact on the immune system. Laughter is associated with a decreased production of inflammatory cytokines both in the general population and in rheumatoid arthritis (RA). Our objective was to explore the effects of humor on serum cytokines [particularly interleukin-6 (IL-6)] and cortisol levels in systemic lupus erythematosus (SLE), after a standard intervention (120 min of visual comedy). We enrolled 58 females with SLE from consecutive patients assessed in the Montreal General Hospital lupus clinic. The subjects who consented to participate were randomized in a 1:1 ratio to the intervention (watching 120 min of comedy) or control group (watching a 120 min documentary). Measurements of cytokine and serum cortisol levels as well as 24-h urine cortisol were taken before, during, and after the interventions. We compared serum cytokine levels and serum and 24-h urine cortisol levels in the humor and control groups and performed regression analyses of these outcomes, adjusting for demographics and the current use of prednisone. There were no significant differences between the control and humor groups in demographics or clinical variables. Baseline serum levels of IL-6, IL-10, tumor necrosis factor-alpha, and B-cell activating factor were also similar in both groups. There was no evidence of a humor effect in terms of decreasing cytokine levels, although there was some suggestion of lowered cortisol secretion in the humor group based the 24-h urinary cortisol levels in a subgroup. In contrast to what has been published for RA, we saw no clear effects of humor in altering cytokine levels in SLE, although interesting trends were seen for lower cortisol levels after humor intervention compared with the control group.

    The selectivity of a zeolite catalyst for hydrocracking of linear hydrocarbons is markedly improved by a controlled calcining during preparation. Several active components are deposited on the zeolite so that a catalyst composition of 0.7 to 1.2 Na/sub 2/OxAl/sub 2/O/sub 3/x4.7 to 5.3 SiO/sub 2/xx H/sub 2/O with x = 3 to 9 is formed. At least during the first calcining step at end temperatures of 400 to 550/sup 0/C a fixed partial pressure of water vapor is maintained in the atmosphere around the material in dependence of its temperature.

    Fatty liver disease plays an important role in the development of type 2 diabetes. Accurate techniques for detection and quantification of liver fat are essential for clinical diagnostics. Chemical shift-encoded magnetic resonance imaging (MRI) is a simple approach to quantify liver fat content. Liver fat quantification using chemical shift-encoded MRI is influenced by several bias factors, such as T2* decay, T1 recovery and the multispectral complexity of fat. The confounder corrected proton density fat fraction is a simple approach to quantify liver fat with comparable results independent of the software and hardware used. The proton density fat fraction is an accurate biomarker for assessment of liver fat. An accurate and reproducible quantification of liver fat using chemical shift-encoded MRI requires a calculation of the proton density fat fraction. (orig.)

    Humor seems to manifest differently in Western and Eastern cultures, although little is known about how culture shapes humor perceptions. The authors suggest that Westerners regard humor as a common and positive disposition; the Chinese regard humor as a special disposition particular to humorists, with controversial aspects. In Study 1, Hong Kong participants primed with Western culture evaluate humor more positively than they do when primed with Chinese culture. In Study 2a, Canadians evaluate humor as being more important in comparison with Chinese participants. In Study 2b, Canadians expect ordinary people to possess humor, while Chinese expect specialized comedians to be humorous. The implications and limitations are discussed.

    In a plant for generating producer gas from fossil fuels with relatively high humidity, there is predrying of the wet material in two drying chambers situated above the actual reactor shaft. The drying air required for this purpose is drawn off via blowers and heat exchangers preheated from the area of the combustion zone. The preparation of the crude gases produced first in the process is done by a socalled bypass gas system, i.e. the reintroduction of the crude gases enriched with tar oil and steam and diverting prepared hot gases via an annular pipe from the area of the reduction zone.

    One of the most crucial constraints in operation of electrical power supply systems is the permanent balance between generation and load. Reserve power is held ready to be able to keep this balance also in case of the occurrence of unpredictable events like power plant outages or inevitable deviations of power injections from their predicted values. At this, the allocation of operating reserves is in the field of conflict between level of reliability and cost effectiveness. The amount of reserve generation capacity required in a control area heavily depends on prediction quality which constitutes the need for high quality predictions. This article is about the influence of prediction quality on the amount of reserve generation capacity required in a control area. The algorithms for the assessment of required reserve generation capacity known from literature use the variation calculus technique to account for the aforementioned unpredictable events and prediction errors. In this article, an extension to a convolution-based method is presented in which the uncertainties of the predictions are expressed using intervals. Each parameter is represented by an independent dimension, assuming statistical independence among them. This allows the distinct analysis of each parameter's influence on the amount of required reserve generation capacity. In addition, two methods for the visualization of the multi-dimensional results are presented, allowing a comprehensive analysis of the parameters' influences. Standard distribution functions are used to represent the parameters for the simulation and the results are shown as probability density functions of possible imbalances. Based on forecasts of the development of conventional power plants and regenerative generation in the years 2020, 2030 and 2040, the required control power of the future German transmission system is calculated. Influences and dependencies are identified with the extended convolution-based method. (orig.)

    Today's raising demand for energy relies to a degree of 85% on the consumption of fossil fuels. A change to regenerative forms of energy is an important and inevitable step in order to face the challenges of climate change and fading natural resources. Photovoltaic's (PV) plays a special role within the various forms of renewable energy since it converts sunlight, our most important and virtually endless energy source, directly into electricity. However, currently available PV-systems are still very expensive and, in combination with their relatively low performance, can hardly or cannot compete with conventional sources of energy from an economical point of view. One possibility to overcome this problem is the combination of highly efficient multi junction solar cells with cost-efficient concentrator optics that focus the incident sunlight to a small spot. The material system (GaIn)(NAs) is envisioned to play an important role in a future generation of multi junction solar cells for concentrator applications being a further development of existing device concepts. However, especially the carrier diffusion lengths in (GaIn)(NAs)-based solar cell layers are currently to low for the fabrication of highly efficient PV-structures. In this work, two novel techniques for the characterization of solar cells are developed and evaluated by experiments on test structures and numerical simulations. Both are based on the measurement of laser-induced currents. Spatially-resolved photocurrent spectroscopy (SRPS) allows a spatially-resolved determination of locally induced photocurrents at a fixed bias voltage while spatially-resolved IV-characteristics (SRIV) are measurements of local I-V-characteristics at a certain position. It is found that SRPS and SRIV allow for a reliable and meaningful characterization of solar cell prototypes with a high spatial resolution. Especially the local p-n-parameters of the sample become accessible. These are the short circuit current, the saturation current, the ideality factor and the excitation-induced shunt resistance. Subsequently, SRPS and SRIV served as characterization techniques for the evaluation of annealing experiments on processed (GaIn)(NAs) solar cell layers for concentrator applications. The goal of these experiments was to improve the material quality of such structures by treating them with high electrical currents and strong lasers pulses. Such enhanced devices could be used in a future generation of PV-systems leading to a significantly increased efficiency. Concerning this some first achievements were made. The use of high electrical currents led to a significant increase of the short circuit current, especially if applied as reverse bias. However, this also caused a reduction of the shunt resistance which eventually dropped down to a few ohms. The application of intensive laser radiation led under certain conditions to a considerable increase of the carrier lifetime and photoluminescence but no improvement of the electrical properties of the devices could be found. A second project dealt with the effect of carrier-depletion on the evaluation of data obtained by the variable stripe length method which is a technique for measuring the optical gain of potential laser materials. Numerical simulations and accompanying experiments on a GaAs-quantum well structure showed that this approach is only valid within a small parameter range. Outside this range an unavoidable carrier depletion caused by stimulated emission processes leads to significant errors in the obtained results. The determination of the corresponding borders is very complicated and requires a detailed knowledge of the sample properties. As the variable stripe length method is typically used to get a first insight into the properties of a novel sample such knowledge is generally missing. Therefore the reliability of experimental results obtained by this technique is doubtful.

    The viscosity of 13 different spices and dried vegetables in total was measured. Optimal conditions were first determined for each product, i.e. concentration, pH-value, temperature, particle size and soaking time. For method evaluation, examinations were primarily performed to study the effect of storage, the reproducibility and the influence of the different varieties of the same spice. In supplement, for pepper, the viscosity was measured as a function of radiation dose. In summation, significant changes in the gel forming capability after irradiation could be observed after preliminary experiments in 8 dried spices (ginger, carrots, leek, cloves, pepper, celery, cinnamon and onions). With 3 spices (ginger, pepper and cinnamon) could the results from examining all different varieties of the same spice be substantiated. An additional influence of storage time on viscosity could not be proved during the investigative period of 8 months. Generally seen, there is no possibility of being able to identify an irradiated spice on the basis of viscosity measurements alone, since the difference between the varieties of one and the same spice is considerably great. However, radiation treatment can be reliably excluded with ginger, pepper and cinnamon, if the viscosities are high (10-20 Pa x s).

By using a double-turn separation-nozzle stage as a preseparation stage in combination with a low-temperature separator, one can reduce the ratio of the buffer input stream to the product stream, in contrast with the solution used up to this time, with only a slight increase in cost of about an order of magnitude. The control program in the case of return feeding of the UF6 from the buffer and the danger of production losses connected with it are thereby correspondingly diminished. An example is given of the enrichment of 235U using the title facility with UF6.

    In a process for producing a gas largely free of inert gases for the synthesis of alcohols, particularly methanol, and of hydrocarbons from coal or heavy hydrocarbons by gasification under pressure with oxygen and steam, the crude gas is cooled, the impurities are removed by washing with methanol and the methanol is removed from the cold pure gas by molecular sieves. The pure gas is then cooled further by evaporation and methane is distilled from the liquid part while simultaneously obtaining the synthetic gas consisting of hydrogen and carbon monoxide which is largely free of methane. The methane is wholly or partly compressed and then split into carbon monoxide and hydrogen using steam and oxygen. The split gas is fed back and mixed with the synthesis gas or the partly cleaned crude gas. The synthesis gas heated to the ambient temperature, freed of impurities and free of methane is compressed to the required synthesis pressure.

Standardverfahren der bildgebenden Lungendiagnostik sind die Computertomographie (CT) zur morphologischen Darstellung und die Perfusions-/Ventilationsszintigraphie bzw. ''single photon emission computed tomography'' (SPECT) zur funktionellen Diagnostik. Zur Darstellung der Lungenventilation stehen die MRT mit hyperpolarisierten Gasen, die O{sub 2}-verstaerkte MRT, die MRT mit fluorierten Gasen und die Fourier-Dekompositions-MRT (FD-MRT) zur Verfuegung. Zur Perfusionsbestimmung koennen die dynamische kontrastmittelverstaerkte MRT (DCE-MRT), das ''arterial spin labeling'' (ASL) und die FD-MRT verwendet werden. Bildgebende Verfahren erlauben einen genaueren Einblick in die Pathophysiologie der Lungenfunktion auf regionaler Ebene. Vorteile der MRT sind die fehlende Strahlenbelastung, welche die schonende Akquisition dynamischer Daten ermoeglicht sowie die Vielfalt der verfuegbaren Kontraste und damit zugaenglichen Parameter der Lungenfunktion. Ausreichende klinische Daten existieren nur fuer bestimmte Anwendungen der DCE-MRT. Fuer die uebrigen Verfahren gibt es lediglich Machbarkeitsstudien und Fallserien mit unterschiedlichem Umfang. Hyperpolarisierte Gase sind technisch bedingt nur eingeschraenkt in der Klinik anwendbar. Ein klinischer Einsatz der genannten Verfahren sollte mit Ausnahme der DCE-MRT nur innerhalb von Studien erfolgen. (orig.)

    Electrokinetic Remediation is a coming up technology for the clean up of contaminated sites based on the electrokinetic phenomena in fine grained sediments. The following investigations offer theoretical and experimental consideration about the dependence of electrokinetic remediation techniques on the clay mineralogical composition of various clays. Finally, laboratory tests on the electroosmotic remediation of a chromate contaminated loess loam are presented. Different voltages applied led to important changes in the direction of chromate transport. When using low voltage (1 V) chromate transport was in the direction of water flow, and an increase of chromate in the effluent of the cathode could be measured. In contrast the application of high voltages up to 30 V changed the transport mechanism and high concentrations of chromate chould be detected in the anode reservoir. The results show that the clay mineral composition and the applied electric field controls the electroosmotic permeability, removal efficiency as well as the transport mechanism of the electrokinetic remediation technology in fine grained sediments.

    Peripheral arterial occlusive disease (PAOD) is still an extremely important politico-economic disease. Diverse treatment procedures exist but the pillars of therapy are changes in lifestyle, such as nicotine abstinence and walking exercise as well as drug therapy. Further therapy options are considered after conventional procedures have been exhausted. These further options consist of improvement of the blood supply by surgical or minimally invasive procedures. The latter therapy options include balloon dilatation and stenting as the most widely used techniques. More recent techniques also used are cryoplasty, laser angioplasty, drug-coated stents or balloons as well as brachytherapy or atherectomy, whereby this list makes no claims to completeness. The multitude of different treatment methods emphatically underlines the fact that no resounding success can be achieved with one single method. The long-term results of both balloon dilatation and stenting techniques show a need for improvement, which elicited the search for additional methods for the treatment of PAOD. Atherectomy represents such an alternative method for treatment of PAOD. Basically, the term atherectomy means the removal of atheroma tissue. For percutaneous atherectomy, in contrast to surgical procedures, it is not necessary to create surgically access to the vessel but accomplishes the atherectomy by means of dedicated systems via a minimally invasive access. There are two basic forms of mechanical atherectomy: directional and rotational systems. (orig.)

  10. Humor as a Mental Fitness Indicator

    2008-10-01

    Full Text Available To explain the pervasive role of humor in human social interaction and among mating partner preferences, Miller (2000a proposed that intentional humor evolved as an indicator of intelligence. To test this, we looked at the relationships among rater-judged humor, general intelligence, and the Big Five personality traits in a sample of 185 college-age students (115 women, 70 men. General intelligence positively predicted rater-judged humor, independent of the Big Five personality traits. Extraversion also predicted rater-judged humor, although to a lesser extent than general intelligence. General intelligence did not interact with the sex of the participant in predicting rating scores on the humor production tasks. The current study lends support to the prediction that effective humor production acts as an honest indicator of intelligence in humans. In addition, extraversion, and to a lesser extent, openness, may reflect motivational traits that encourage humor production.

    Full Text Available Pulpitis is an inflammation process on dental pulp tissue, and usually as the continuous of caries. The microorganism in the caries is a potential immunogenic triggering the immune respons, both humoral and celluler immune responses. The aim of this research is to explain the humoral immune response changes in the dental pulp tissues of pulpitis. This research was done on three group samples: Irreversible pulpitis, Reversible pulpitis and sound teeth as the control group. The result showed that there were three pulpitis immunopathologic patterns: the sound teeth immunopathologic pattern showing a low humoral immune response, in a low level of IgG, IgA and IgM, the reversible pulpitis pattern showing that in a higher humoral immune response, IgG and IgA decreased but IgM increased, the irreversible pulpitis pattern showing that IgG and IgM increased, but it couldn't be repaired although it has highly immunity, and it showed an unusually low level of IgA. This low level of IgA meant that irreversible pulpitis had a low mucosal immunity.

    Research has shown that a factor in a victim's forgiveness of an offender is the victim's ability to make more positive, or at least less negative, attributions of the offender's behavior and that perspective-taking can be a factor in facilitating that process. Self-enhancing humor has been found to be positively correlated with perspective-taking empathy and aggressive humor found to be negatively correlated with perspective-taking empathy. Therefore it was predicted that self-enhancing humor would be positively correlated with forgiveness and aggressive humor negatively correlated with forgiveness. The Humor Styles Questionnaire, the Absence of Negative and Presence of Positive subscales of the Forgiveness Scale, and the Forgiveness Likelihood Scale were administered to 112 college undergraduates. Self-enhancing humor was significantly and positively correlated with all of the forgiveness measures, aggressive humor and self-defeating humor were significantly and negatively correlated with some of the forgiveness measures and affiliative humor was not significantly correlated with any of the forgiveness measures. The results were interpreted in terms of previous findings for humor styles, perspective-taking empathy, depression, self-esteem and anxiety. Future research involving the extent to which other personality variables, such as perspective-taking empathy, mediate the relationship between self-enhancing humor and forgiveness was suggested.

    Full Text Available A corpus of 313 freshman college essays was analyzed in order to better understand the forms and functions of humor in academic writing. Human ratings of humor and wordplay were statistically aggregated using Factor Analysis to provide an overall Humor component score for each essay in the corpus. In addition, the essays were also scored for overall writing quality by human raters, which correlated (r = .195 with the humor component score. Correlations between the humor component scores and linguistic features were examined. To investigate the potential for linguistic features to predict the Humor component scores, regression analysis identified four linguistic indices that accounted for approximately 17.5% of the variance in humor scores. These indices were related to text descriptiveness (i.e., more adjective and adverb use, lower cohesion (i.e., less paragraph-to-paragraph similarity, and lexical sophistication (lower word frequency. The findings suggest that humor can be partially predicted by linguistic features in the text. Furthermore, there was a small but significant correlation between the humor and essay quality scores, suggesting a positive relation between humor and writing quality.

    Full Text Available GnRH-Analoga haben eine große Bedeutung in der medikamentösen Therapie der Endometriose erlangt. Sie sind in der Lage, Endometrioseassoziierte Schmerzen zu beseitigen und sind Bestandteil der Therapie der endometriosebedingten Infertilität. Aufgrund der Chronizität der Endometriose bedarf es in vielen Fällen der Prolongation der GnRH-A-Therapie über den Zeitraum von 6 Monaten hinaus. Für diese Fälle eignet sich eine Add-back- Therapie nach dem Format von Hormonersatztherapien, um vasomotorischen Nebeneffekten und dem Knochensubstanzverlust entgegenwirken zu können. Dabei wird der Estrogenanteil niedrig dosiert eingesetzt, um innerhalb eines "therapeutischen Fensters" den Hypoestrogenismus auszugleichen, ohne das Endometriosewachstum zu fördern. Prinzipiell kann dazu das Estrogen oral, aber auch transdermal appliziert werden. Die Effektivität der Kombination aus GnRH-A plus Add-back bezüglich der Knochenprotektion konnte bereits für einen Zeitraum von bis zu 10 Jahren bestätigt werden, sodass damit eine Langzeitkonzeption für Frauen mit rezidivierender Endometriose und wiederholten operativen Eingriffen existiert. Alternativen zur klassischen Add-back mit Sexualsteroiden existieren vielfältig, aber ihr Einsatz ist durch Partialwirkungen und eigene Nebenwirkungen limitiert.

    If we apply the multistep method of W. Gear for the integration of a system of ordinary differential equations to the nonlinear heat conduction equation in the implementation EPISODE, this results in memory problems due to the band structure of the Jacobian, because EPISODE uses a LU-decomposition with pivoting. The report describes measures which suit this method to the actual conditions. If we use the storage scheme for sparse matrices from Liebau, Rudolphi, only the nonzero elements of the Jacobian are stored. In case of a linear problem, this matrix only has to be computed once. The BI-CGSTAB-method, an iterative method, replaces the LU-decomposition resp. the solution of the linear (and possibly non-symmetric) system of equations resulting from the corrector step. If {tau} is the time step length and h the space step length, this BICG-variant has good convergence properties for a moderate ratio of {tau}/h{sup 2}. The report also includes a short description of the program INSTATCP developed in Borland Delphi 4/Object Pascal. Two applications from the field of fire protection and thermal insulation in buildings (fire insulated steel column and vertically perforated brick) show that the modifications of the Gear method work effectively. (orig.) [German] Wird das Mehrschnittverfahren von W.

Replicating previous research, happiness was positively correlated with four personality traits: extraversion, locus of control, self-esteem, and optimism. Further, happiness positively related to self-enhancing and affiliative humor styles; it related negatively to self-defeating and aggressive humor styles. Thus, happy people habitually engage in positive uses of humor and avoid engaging in negative uses of humor in daily life. We also found support for our hypothesis. People high in extraversion, locus of control, self-esteem, and optimism are happier because they engage in positive humor in daily life.

Thus, happy people habitually engage in positive uses of humor and avoid engaging in negative uses of humor in daily life. We also found support for our hypothesis. People high in extraversion, locus of control, self-esteem, and optimism are happier because they engage in positive humor in daily life. PMID:27547251

    The most common gas scrubbing process in Europe, i.e. the wet scrubbing process, is described. Preliminary stages are coarse filtering, coarse dehydration and coarse desulphurisation. Carbon dioxide and hydrogen sulphide are absorbed in counterflow in water at a pressure of 6 to 10 bar. The water can be generated by pressure relief and can be recirculated. Plant components like compressors, absorption column, strippers and dryers are gone into as well as the mode of operation and control. [German] Das europaweit zur Aufbereitung von Biogas am meisten genutzte Verfahren der nassen Gaswaesche wird beschrieben. Vorausgehende Reinigungsschritte des Biogases sind Grobfilterung, Grobentfeuchtung und Grobentschwefelung. Kohlendioxid und gleichzeitig H{sub 2}S werden im Gegenstrom unter Druck von 6 bis 10 bar in Wasser absorbiert. Das Wasser kann durch Entspannung regeneriert und im Kreislauf gefuehrt werden. Auf die Komponenten der Anlage wie Kompressor, Absorptionskolonne, Stripper und Trockner wird ebenso eingegangen wie auf die Betriebsfuehrung und Steuerung. (orig.)

    Full Text Available Este artigo examina a construção social e cultural de um estereótipo sobre lésbicas, baseado na percepção de que elas não possuem senso de humor. Analisa-se como lésbicas são retratadas por comediantes, programas de TV,  quadrinhos e na literatura, e compara essas representações a outros  estereótipos, como aqueles relacionados a alemães e gays extravagantes. Ao investigar as relações entre masculinidade, feminilidade e falta de humor, demonstra-se que considerar lésbicas como incompatíveis com o riso e a graça significa caracterizá-las como destituídas de humanidade. The article Humorless lesbians examines the social and cultural construction of a lesbian stereotype, based on the perception that they lack sense of humor. It is analyzed how lesbians are portrayed by comedians, TV shows, comic strips, and in literature. These representations are compared to other stereotypes such as those related to Germans and campy gays. By investigating the relations between masculinity, femininity and humorlessness, it is demonstrated that considering lesbians as incompatible with laughter and fun means to depicting them as deprived of humanity.

    The authors present a method developed at the Institute of Chemical Engineering and Steam Boiler Technology (IVD) of Stuttgart University for quasi-continuous online measurement of tar concentrations in gases from biomass gasification. The method is compared with other methods in terms of time requirements, accuracy, and cost: Gravimetry, wet chemical analysis, solid phase amino-adsorption (SPA), and online process gas chromatography. The measurements were carried out on the fluidized-bed combustion system of the IVD. Wood was gasified at 800 degrees centigrade with a fuel/air ratio of 0.25. The measured tar concentrations differed widely, i.e. between 0.8 and 6.8 g per cubic metre. (orig.)

    Full Text Available Abstract Background The zinc uptake regulator Zur is a Zn2+-sensing metalloregulatory protein involved in the maintenance of bacterial zinc homeostasis. Up to now, regulation of zinc homeostasis by Zur is poorly understood in Y. pestis. Results We constructed a zur null mutant of Y. pestis biovar microtus strain 201. Microarray expression analysis disclosed a set of 154 Zur-dependent genes of Y. pestis upon exposure to zinc rich condition. Real-time reverse transcription (RT-PCR was subsequently used to validate the microarray data. Based on the 154 Zur-dependent genes, predicted regulatory Zur motifs were used to screen for potential direct Zur targets including three putative operons znuA, znuCB and ykgM-RpmJ2. The LacZ reporter fusion analysis verified that Zur greatly repressed the promoter activity of the above three operons. The subsequent electrophoretic mobility shift assay (EMSA demonstrated that a purified Zur protein was able to bind to the promoter regions of the above three operons. The DNase I footprinting was used to identify the Zur binding sites for the above three operons, verifying the Zur box sequence as predicted previously in γ-Proteobacteria. The primer extension assay was further used to determine the transcription start sites for the above three operons and to localize the -10 and -35 elements. Zur binding sites overlapped the -10 sequence of its target promoters, which was consistent with the previous observation that Zur binding would block the entry of the RNA polymerase to repress the transcription of its target genes. Conclusion Zur as a repressor directly controls the transcription of znuA, znuCB and ykgM-RpmJ2 in Y. pestis by employing a conserved mechanism of Zur-promoter DNA association as observed in γ-Proteobacteria. Zur contributes to zinc homeostasis in Y. pestis likely through transcriptional repression of the high-affinity zinc uptake system ZnuACB and two alternative ribosomal proteins YkgM and RpmJ2.

  16. Instructional scientific humor in the secondary classroom

    Science.gov (United States)

    Wizner, Francine

    This study is an examination of the manner in which educators employ scientific content humor and how that humor is perceived by their students. Content humor is a useful strategy in drawing the attention of students and improving their receptivity toward scientific information. It is also a useful tool in combating the growing distractions of the electronic classroom. Previous studies have found that humor has a positive effect on knowledge, memory, and understanding. However, few studies have been conducted below the undergraduate level and mainly quantitative measures of student recall have been used to measure learning. This study employed multiple data sources to determine how two secondary biology teachers used humor in order to explain scientific concepts and how their students perceived their teachers' use of scientific instructional humor. Evidence of student humor reception was collected from four students in each of the two classes. All of the scientific instructional humor used in the studied classrooms was cognitive in nature, varying among factual, procedural, conceptual, and metacognitive knowledge. Teachers tended to use dialogic forms of humor. Their scientific humor reflected everyday experiences, presented queries, poked fun at authority, and asked students to search out new perspectives and perform thought experiments. Teachers were the primary actors in performing the humorous events. The events were sometimes physical exaggerations of words or drawings, and they occurred for the purpose of establishing rapport or having students make connections between scientific concepts and prior knowledge. Student perceptions were that teachers did employ humor toward instructional objectives that helped their learning. Helping students become critical thinkers is a trademark of science teachers. Science teachers who take the risk of adopting some attributes of comedians may earn the reward of imparting behaviors on their students like critical thinking

    To evaluate aqueous humor viscosity in the raptor, dog, cat, and horse, with a primary focus on the barred owl (Strix varia). Twenty-six raptors, ten dogs, three cats, and one horse. Animals were euthanized for reasons unrelated to this study. Immediately, after horizontal and vertical corneal dimensions were measured, and anterior chamber paracentesis was performed to quantify anterior chamber volume and obtain aqueous humor samples for viscosity analysis. Dynamic aqueous humor viscosity was measured using a dynamic shear rheometer (AR 1000 TA Instruments, New Castle, DE, USA) at 20 °C. Statistical analysis included descriptive statistics, unpaired t-tests, and Tukey's test to evaluate the mean ± standard deviation for corneal diameter, anterior chamber volume, and aqueous humor viscosity amongst groups and calculation of Spearman's coefficient for correlation analyses. The mean aqueous humor viscosity in the barred owl was 14.1 centipoise (cP) ± 9, cat 4.4 cP ± 0.2, and dog 2.9 cP ± 1.3. The aqueous humor viscosity for the horse was 1 cP. Of the animals evaluated in this study, the raptor aqueous humor was the most viscous. The aqueous humor of the barred owl is significantly more viscous than the dog (P humor viscosity of the raptor, dog, cat, and horse can be successfully determined using a dynamic shear rheometer. © 2014 American College of Veterinary Ophthalmologists.

    Cognitive distortions are negative biases in thinking that are theorized to represent vulnerability factors for depression and dysphoria. Despite the emphasis placed on cognitive distortions in the context of cognitive behavioural theory and practice, a paucity of research has examined the mechanisms through which they impact depressive symptomatology. Both adaptive and maladaptive styles of humor represent coping strategies that may mediate the relation between cognitive distortions and depressive symptoms. The current study examined the correlations between the frequency and impact of cognitive distortions across both social and achievement-related contexts and types of humor. Cognitive distortions were associated with reduced use of adaptive Affiliative and Self-Enhancing humor styles and increased use of maladaptive Aggressive and Self-Defeating humor. Reduced use of Self-Enhancing humor mediated the relationship between most types of cognitive distortions and depressed mood, indicating that distorted negative thinking may interfere with an individual's ability to adopt a humorous and cheerful outlook on life (i.e., use Self-Enhancing humor) as a way of regulating emotions and coping with stress, thereby resulting in elevated depressive symptoms. Similarly, Self-Defeating humor mediated the association of the social impact of cognitive distortions with depression, such that this humor style may be used as a coping strategy for dealing with distorted thinking that ultimately backfires and results in increased dysphoria.

    2006-01-01

    Full Text Available Humor is a complex cognitive function which often leads to laughter. Contemporary humor theorists have begun to formulate hypotheses outlining the possible innate cognitive structures underlying humor. Humor's conspicuous presence in the behavioral repertoire of humankind invites adaptive explanations. This article explores the possible adaptive features of humor and ponders its evolutionary path through hominid history. Current humor theories and previous evolutionary ideas on humor are reviewed. In addition, scientific fields germane to the evolutionary study of humor are examined: animal models, genetics, children's humor, humor in pathological conditions, neurobiology, humor in traditional societies and cognitive archeology. Candidate selection pressures and associated evolutionary mechanisms are considered. The authors conclude that several evolutionary-related topics such as the origins of language, cognition underlying spiritual feelings, hominid group size, and primate teasing could have special relevance to the origins of humor.

    Full Text Available This study examined women’s and men’s preferences for humor production and humor receptivity in long-term and short-term relationships, and how these factors interact with physical attractiveness to influence desirability. Undergraduates viewed photographs of the opposite sex individuals who were high or low in physical attractiveness, along with vignettes varying in humor production and receptivity. Participants rated physical attractiveness and desirability for long-term and short-term relationships. The main findings were that individuals desired partners who were high in humor production and receptivity, though the effects were particularly pronounced for women judging long-term relationships. Moreover, humor production was more important than receptivity for women’s ratings of male desirability. Notably, we also found that ratings of physical attractiveness were influenced by the humor conditions. These results are discussed in terms of the fitness indicator, interest indicator, and encryption hypotheses of the evolutionary functions of humor.

    This paper is based upon the writings of William James in the late 19th century, and Alfred Adler and Sigmund Freud in the 20th, enriched by the contributions of later personality and role theorists. The self is defined as the unique organization of each person; a style is the self in action. Different life styles and their components are expressed in different situations. I posit that humor and positive thinking, combined with meaning and purpose, are vital components of all constructive life styles. The knowledge of life styles cuts through diagnostic labels to reveal our universal humanity. It can be fruitfully applied to patients and nonpatients alike and, I found, for the self-understanding of therapist. The clinical application of life styles is illustrated through numerous vignettes.

    Full Text Available Ética del humor es una obra original, abundantemente documentada, de contenido científico y filosófico, que aborda un problema de gran importancia en los actuales estudios de éticas aplicadas. La ética del humor es una nueva ética aplicada que pretende comprender el fenómeno del humor a la luz de sus implicaciones éticas. Como señala el autor, Juan Carlos Siurana, reputado experto en el ámbito de la filosofía práctica, el interés por el humor es un interés por la ética. En la obra no presenta una nueva teoría filosófica del humor –las cuales se han venido sucediendo, al menos, desde los Diálogos de Platón–, sino una nueva teoría ética, que toma al humor como objeto principal de análisis. Por tanto, la finalidad es realizar una aportación dentro del ámbito de la ética. Para ello se nutre de distintos estudios psicológicos, biológicos, fisiológicos y neurológicos sobre el humor, así como de clásicas obras de filosofía que han abordado esta cuestión.

    The aim of the project was to contribute to enhanced service life and reliability of batteries in photovoltaic systems by developing further processes and components for charge measurement. The essential basic information in charge determination is the direct measurement of acid concentration in the electrolyte compartment of lead batteries and the evaluation and processing of this signal. Within the framework of this project, operative acidity sensors were developed and tested. They are accurate within an error margin of 0.5 per cent for short periods and of 2 per cent for long periods. A charge measurement unit based on the acid concentration reading was built and special algorithms for measuring charge were developed and tested. This unit stands out particularly because of the following: determination of dynamic charge, long-term stability, and automatic and regular adaptation to the type, size and age of the battery. Using this unit in combination with the acid concentration sensor in photovoltaic plant will permit more efficient plant operation and reliable protection of the battery. (orig./MM) [Deutsch] Ziel des Vorhabens war es, Massnahmen zur Verbesserung der Lebensdauer und Zuverlaessigkeit von Batterien in PV-Anlagen durch die konkrete Weiterentwicklung von Verfahren und Komponenten zur Ladezustandserfassung aufzuzeigen, durchzufuehren und zu demonstrieren. Die direkte Messung der Saeuredichte im Elektrolytraum von Bleibatterien sowie die Auswertung und Weiterverarbeitung dieses Signals bildet dabei die wesentliche Basisinformation. Im Rahmen des Vorhabens wurden funktionstuechtige Saeuredichtesensoren entwickelt und erprobt. Die dabei erreichte Genauigkeit betraegt im Kurzzeitbereich 0,5% und im Langzeitbereich ca. 2%. Eine Ladezustandseinheit basierend auf dem Saeuredichtesignal wurde aufgebaut und spezielle Algorithmen zur Ladezustandserfassung entwickelt und getestet. Besonders die Bestimmung des dynamischen Ladezustands, die Langzeitstabilitaet sowie

    Unlike passive humor appreciation, the neural correlates of real-time humor creation have been unexplored. As a case study for creativity, humor generation uniquely affords a reliable assessment of a creative product's quality with a clear and relatively rapid beginning and end, rendering it amenable to neuroimaging that has the potential for reflecting individual differences in expertise. Professional and amateur "improv" comedians and controls viewed New Yorker cartoon drawings while being scanned. For each drawing, they were instructed to generate either a humorous or a mundane caption. Greater comedic experience was associated with decreased activation in the striatum and medial prefrontal cortex (mPFC), but increased activation in temporal association regions (TMP). Less experienced comedians manifested greater activation of mPFC, reflecting their deliberate search through TMP association space. Professionals, by contrast, tend to reap the fruits of their spontaneous associations with reduced reliance on top-down guided search.

    El humor es un fenómeno demasiado complejo para ser explicado fácilmente, sin embargo la risa, es una de las formas más admirables del comportamiento humano. El humor forma parte de nuestra vida cotidiana y todos tenemos de él, ya desde nuestra más tierna infancia un conocimiento intuitivo. Muchos saben que el humor mejora las relaciones humanas, puede favorecer una cierta distensión y facilita el bienestar de todos los miembros de una empresa, dirigentes, empleados y obreros. Muchos esperan encontrar en él la forma de resolver los conflictos y de reducir la agresividad. Allí donde se encuentren hombres, existe el humor, comprenderlo mejor y utilizarlo más libremente y en el momento oportuno, puede ayudarnos a hacer nuestra vida más agradable.

    A device for the controlled addition of fuels especially baking fuels into a fluidized-bed reactor is equipped with a jet pipe for the fuel transport which ends within the fluidized-bed reactor in a jet nozzle and is sheathed by a jacket pipe which ends in a cap jet and is filled with a fluid (jacket fluid); the jacket pipe is interrupted by the jet cap and the interruption is bypassed by a heat exchanger pipe (heat exchanger) which is preferably arranged within the fluidized-bed reactor. The part of the jet pipe which is near the jet nozzle can be surrounded by an annular gap nozzle for the jacket fluid bypassing the interruption in direction of the heat exchanger. In a mixing chamber loading materials for the fuel can be introduced and dissolved in the jacket fluid before it enters the cap jet. The fuel transport can be clock-controlled, e.g. by a control triangle. (orig.).

  13. Neuropsychology of humor: an introduction. Part II. Humor and the brain.

    Derouesné, Christian

    2016-09-01

    Impairment of the perception or comprehension of humor is observed in patients with focal brain lesions in both hemispheres, but mainly in the right frontal lobe. Studies by functional magnetic resonance imaging in healthy subjects show that humor is associated with activation of two main neural systems in both hemispheres. The detection and resolution of incongruity, cognitive groundings of humor, are associated with activation of the medial prefrontal and temporoparietal cortex, and the humor appreciation with activation of the orbito-frontal and insular cortex, amygdala and the brain reward system. However, activation of these areas is not humor-specific and can be observed in various cognitive or emotional processes. Event-related potential studies confirm the involvement of both hemispheres in humor processing, and suggest that left prefrontal area is associated with joke comprehension and right prefrontal area with the resolution stage. Humor thus appears to be a complex and dynamic functional process involving, on one hand, two specialized but not specific neural systems linked to humor apprehension and appreciation, and, on the other hand, multiple interconnected functional brain networks including neural patterns underlying the moral framework and belief system, acquired by conditioning or imitation during the cognitive development and social interactions of the individual, and more distributed systems associated with the analysis of the current context of humor occurrence. Disturbances of the sense of humor could then result from focal brain alterations localized in one or two of the specialized areas underlying the comprehension or appreciation of humor, or from perturbations of the network interconnectivity in non-focal brain disorders such as Alzheimer's disease or schizophrenia.

    If the same type of biomass is harvested at different times, preserved by different technques and then processed into fuel, the physical and chemical characteristics of the fuel will differ. After describing biomass fuel of the `wet line`, the author carried out investigations of lumpiness, bulk density and materials density of chopped materials in order to obtain a preliminary physical characterisation. Two samples of wood chips were characterized as well. The chemical description started with an analysis of nutrient content, acidity and concentrations of fermentation acids in the `wet line` biomass. (orig.)

  20. Sense of Humor, Stable Affect, and Psychological Well-Being

    2014-08-01

    Full Text Available A good sense of humor has been implicated as a quality that could contribute to psychological well-being. The mechanisms through which sense of humor might operate include helping to reappraise threats, serving as a character strength, or facilitating happiness. The current research attempts to integrate these possibilities by examining whether a good sense of humor might operate globally by helping to maintain a more stable positive affect. Stable positive affect has been shown to facilitate more effective problem solving and to build resilience. However, not all humor is adaptive humor, so we also examine the roles that different styles of humor use might play. Individual differences in humor styles were used to predict stable levels of affect. Then, in a longitudinal design, humor styles and stable affect were used to predict subsequent resilience and psychological health. The results indicated that stable affect was related to resilience and psychological well-being, and that a sense of humor that involves self-enhancing humor, humor based on maintaining a humorous perspective about one’s experiences, was positively related to stable positive affect, negatively related to stable negative affect, and was mediated through stable affect in influencing resilience, well-being and distress. Thus, while a good sense of humor can lead to greater resilience and better psychological health, the current results, focusing on stable affect, find only self-enhancing humor provides reliable benefits.

    Humor is sometimes employed in health messages. However, little is known about contingencies under which different types of humor may or may not be effective. This experiment crossed humorous vs. non-humorous and self- vs. other-deprecating messages about binge drinking, and tested how differences in personal investment in alcohol use moderates the effects of such messages on college binge drinkers. Results showed significant three-way interaction effects on subjective norms and behavioral intentions largely consistent with hypotheses. Assessment of significant differences in the interactions indicated that for binge drinkers who weren’t high in personal investment in alcohol use, other-deprecating humor tended to reduce their perceived subjective norms about the acceptability of binge drinking behavior and their behavioral intentions. The effect of the experimental manipulation on subjective norms among these binge drinkers was shown to mediate the effect on intentions to binge drink in the future. Theoretical and practical implications are discussed. PMID:26020507

    2008-09-01

    It has become critical that learners are exposed to varied methods of teaching and assessment that will promote critical thinking of learners. Humor creates a relaxed atmosphere where learning can be enhanced and appreciated. When learners are relaxed, thinking becomes eminent. Authoritative and tense environment hinders thinking. This paper seeks to explore the perceptions of nurse teacher learners regarding the use of humor as a pedagogical tool to promote learning. A qualitative, exploratory, descriptive and contextual research design was employed (Burns & Grove, 2001:61; Mouton, 1996:103). 130 naive sketches were collected from nurse teacher learners who volunteered to take part in the study (Giorgi in_Omery, 1983:52) Follow up interviews were conducted to verify the findings. A qualitative, open-coding method of content analysis was done Tesch (in Creswell, 1994:155). Measures to ensure trustworthiness of the study were taken in accordance with the protocol of (Lincoln & Guba, 1985:290-326). The findings of the study will assist the nurse educators to create a positive, affective, psychological and social learning environment through the use of humor in a positive manner. Nurse educators will appreciate the fact that integration of humor to the learning content will promote the learners' critical thinking and emotional intelligence. Negative humor has a negative impact on learning. Learner nurses who become critical thinkers will be able to be analytical and solve problems amicably in practice.

    Playfulness has been referred to as a disposition that involves reframing a situation to amuse others and to make the situation more stimulating and enjoyable. It may serve to shift one's perspective when dealing with environmental threats. Despite all the benefits of playfulness towards psychological well-being, it remains a largely understudied subject in psychology, particularly in Chinese societies. Hence, this study examined the association between adult playfulness, humor styles, and subjective happiness among a sample of 166 university students in Hong Kong and 159 students in Guangzhou, who completed a self-administered questionnaire, including the Short Measure for Adult Playfulness, the Chinese Humor Styles Questionnaire, and the Subjective Happiness Scale. Results showed that adult playfulness was positively correlated with affiliative humor, self-enhancing humor, and subjective happiness in both Hong Kong and Guangzhou samples. By its implication, highly playful Chinese students preferred using affiliative and self-enhancing humor to amuse themselves and others. © The Author(s) 2016.

  6. Anomalous hypothalamic responses to humor in cataplexy.

    2008-05-01

    Full Text Available Cataplexy is observed in a subset of patients with narcolepsy and affects approximately 1 in 2,000 persons. Cataplexy is most often triggered by strong emotions such as laughter, which can result in transient, yet debilitating, muscle atonia. The objective of this study was to examine the neural systems underlying humor processing in individuals with cataplexy.While undergoing functional Magnetic Resonance Imaging (fMRI, we showed ten narcolepsy-cataplexy patients and ten healthy controls humorous cartoons. In addition, we examined the brain activity of one subject while in a full-blown cataplectic attack. Behavioral results showed that participants with cataplexy rated significantly fewer humorous cartoons as funny compared to controls. Concurrent fMRI showed that patients, when compared to controls and in the absence of overt cataplexy symptoms, showed pronounced activity in the emotional network including the ventral striatum and hypothalamus while viewing humorous versus non-humorous cartoons. Increased activity was also observed in the right inferior frontal gyri--a core component of the inhibitory circuitry. In comparison, the one subject who experienced a cataplectic attack showed dramatic reductions in hypothalamic activity.These findings suggest an overdrive of the emotional circuitry and possible compensatory suppression by cortical inhibitory regions in cataplexy. Moreover, during cataplectic attacks, the hypothalamus is characterized by a marked decrease in activity similar to that observed during sleep. One possible explanation for these findings is an initial overdrive and compensatory shutdown of the hypothalamus resulting in full cataplectic symptoms.

  7. Humor as Wisdom for Reframing Life.

    Human beings inevitably experience anxiety but attempt to avoid facing it through various forms of self-deception. This avoidance can lead to pathological symptoms. Young and middle-aged adults may be especially susceptible to suffering from anxiety because they are often single-mindedly pursuing means of achieving security. For these and others who fail to embrace life with warm enthusiasm, humor can serve to alleviate stress. This article views humor as a characteristic disposition of older adults-their humor signifying a sense of integrity and wisdom that often accompanies the aging process. Humor binds together feelings of despair and joy and contributes to a faithful reframing of faith and life. This article proposes that individuals acquire humor by perceiving the world as if on a journey to an exotic new place, seeing with new eyes even the most mundane of everyday objects and events. This capacity to perceive beauty in the ordinary world reflects a wisdom of older adults potentially available even to the young.

    The unsteady, turbulent flow is to be calculated in a complex geometry. For this purpose a stabilized finite element formulation in which the same functions for velocity and pressure are used is developed. Thus the process remains independent of the type of elements. This simplifies the application. Above all, it is easier to deal with the boundary conditions. The independency from the elements is also achieved by the extended uzawa-algorithm which uses quadratic functions for velocity and an element-constant pressure. This method is also programmed. In order to produce the unstructured grids, an algorithm is implemented which produces meshes consisting of triangular and tetrahedral elements with flow-dependent adaptation. With standard geometries both calculation methods are compared with results. Finally the flow in a draft tube of a Kaplan turbine is calculated and compared with results from model tests. (orig.) [German] Die instationaere, turbulente Stroemung in einer komplexen Geometrie soll berechnet werden. Dazu wird eine Stabilisierte Finite Element Formulierung entwickelt, bei der die gleichen Ansatzfunktionen fuer Geschwindigkeiten und Druck verwendet werden. Das Verfahren wird damit unabhaengig von der Form der Elemente. Dies vereinfacht die Anwendung. Vor allem wird der Umgang mit den Randbedingungen erleichert. Die Elementunabhaengigkeit erreicht man auch mit dem erweiterten Uzawa-Algorithmus, welcher quadratische Ansatzfunktionen fuer die Geschwindigkeiten und elementweisen konstanten Druck verwendet. Dieses Verfahren wird ebenso implementiert. Zur Erstellung der unstrukturierten Gitter wird ein Algorithmus erzeugt, der Netze aus Dreiecks- und Tetraederelementen erstellt, welche stroemungsabhaengige Groessen besitzen koennen. Anhand einiger Standardgeometrien werden die beiden Berechnungsmethoden mit Ergebnissen aus der Literatur verglichen.

    This survey study has five parts. In the first part two conceptual approaches to humor are characterized. One considers "the comic" to be an umbrella concept, and humor is only one of its rather positive forms. The other comes out from the umbrella concept "humor", and distinguishes between various forms of humor including the negative ones. Three main theories of humor are presented: theory of superiority, theory of incongruity, and a relief theory. The second part introduces humor in the elderly and draws the attention to the fact that we know relatively little about humor in old age because most research has been carried out in children, adolescents or adults in productive age. The third part of the study describes the process of diagnostics of humor in the elderly. For example, within the qualitative methods, in-depth interviews with seniors or analyses of their diary entries are used. Within quantitative methods, questionnaires are used, and this study presents the survey of seven most frequent ones applied in the studies of humor in the elderly. In the context of mixed methods, understanding of humor in young and seniors, or understanding of humor in relatively healthy seniors and seniors after stroke are compared. The fourth part of the study presents the Gelkopfs model on relationship between humor, treatment and cure of patients. The fifth part of the study demonstrates the options how to use humor to improve the mental state of the elderly (by means of individual or group interventions).

    Humor and laughter are integral parts of human life and communication - and so of course they occur in medical contacts.Humor is defined as a personality based cognitive emotional style of processing situations, characterized by the ability to find positive aspects even in negative situations, and the ability to communicate this point of view to others and to cheer them up. Humor can support healing processes and coping with illness. Humor and jokes reduce anxiety and stress (for patients and doctors). Humorous people have a more realistic, flexible and less fearful behaviour. Humor helps to overcome negative experience. Humor can help the patient to gain new views towards the disease and a healthy distance towards occurring symptoms. Humor improves the relationship between patient and doctor. But beware: jokes can also be used to express fears, aggression or shame. Therefore it is worthwhile to listen carefully to what patients want to express. Humor reduces the risk of burnout. In contact with patients, it is important to give their humor room, to use it and respond to it, more than making jokes. Humor can be trained. Humor training and creation of a humorous atmosphere in health care facilities should also be supported by health insurance funds, institutions' sponsors and public authorities. © Georg Thieme Verlag KG Stuttgart · New York.

    der Gefaesswand zu, allerdings sind nur ausgewaehlte extrakranielle Gefaesse mit ausreichender Aufloesung schallbar. Da den Vaskulitiden primaer Veraenderungen der Gefaesswand zugrunde liegen und die gefundenen luminalen Veraenderungen in der Regel unspezifisch sind und auch bei anderen Erkrankungen auftreten koennen, sind die gebraeuchlichen Verfahren in ihrer Aussagekraft oft limitiert. Mit der hochaufgeloesten MRT der zervikalen und intrakraniellen Gefaesse steht eine viel versprechende neue Methode zur Verfuegung, die die entzuendlich veraenderte Gefaesswand nichtinvasiv und ohne Verwendung ionisierender Strahlen im Detail zu visualisieren vermag. In diesem Beitrag sollen die verwendeten Untersuchungsprotokolle vorgestellt und klinische Bildbeispiele gezeigt werden. Dabei sollen insbesondere die Grossgefaessvaskulitiden und die Vaskulitiden des ZNS behandelt werden. Zudem werden die haeufigsten radiologischen Differenzialdiagnosen demonstriert und andere bildgebende Methoden, wie PET/CT und Ultraschall, die ebenfalls zur Diagnostik der Vaskulitiden eingesetzt werden, diskutiert.

    Full Text Available The present article aims to characterize samples of verbal humor published on the social network Twitter. To do so, an analysis of 81 humorous texts published under the hashtag #otegi during 1 March 2016, on which date Arnaldo Otegi was released from prison after six years, was carried out. A pragmatic study of the tweets was performed, opting for the General Theory of Verbal Humor as a basis. The examination conducted reveals that the manner of presentation of opposing scripts, the logical mechanisms availed of to resolve this kind of incongruity, the special narrative strategies selected and the linguistic choices made are determined at all times by the circumstances in which the texts are presented and the upper limit constraint of 140 characters per Twitter publication.

    Humor is a unique ability in human beings. Suls [A two-stage model for the appreciation of jokes and cartoons. In P. E. Goldstein & J. H. McGhee (Eds.), The psychology of humour. Theoretical perspectives and empirical issues. New York: Academic Press, 1972, pp. 81-100] proposed a two-stage model of humor: detection and resolution of incongruity. Incongruity is generated when a prediction is not confirmed in the final part of a story. To comprehend humor, it is necessary to revisit the story, transforming an incongruous situation into a funny, congruous one. Patient and neuroimaging studies carried out until now lead to different outcomes. In particular, patient studies found that right brain-lesion patients have difficulties in humor comprehension, whereas neuroimaging studies suggested a major involvement of the left hemisphere in both humor detection and comprehension. To prevent activation of the left hemisphere due to language processing, we devised a nonverbal task comprising cartoon pairs. Our findings demonstrate activation of both the left and the right hemispheres when comparing funny versus nonfunny cartoons. In particular, we found activation of the right inferior frontal gyrus (BA 47), the left superior temporal gyrus (BA 38), the left middle temporal gyrus (BA 21), and the left cerebellum. These areas were also activated in a nonverbal task exploring attribution of intention [Brunet, E., Sarfati, Y., Hardy-Bayle, M. C., & Decety, J. A PET investigation of the attribution of intentions with a nonverbal task. Neuroimage, 11, 157-166, 2000]. We hypothesize that the resolution of incongruity might occur through a process of intention attribution. We also asked subjects to rate the funniness of each cartoon pair. A parametric analysis showed that the left amygdala was activated in relation to subjective amusement. We hypothesize that the amygdala plays a key role in giving humor an emotional dimension.

    Full Text Available The main point of this work is to show how humor—when is used properly- has a positive effect on the patient ant the therapist’s self improving their alliance, supervision and team meetings. It’s also good for profesionals to include humor, recreation and rest in their job routines, because these ingredients let them be more effective in psychoterapy. The vast majority of psychological theories agree on its importance. The Cognitive Psychology believes that humor helps the patient evaluate reality in a different way, stops disfunctional thoughts, lets the expression of negative emotions and finds more adaptative patterns.

    The goal of this article is to expose different aspects of the use of humor in therapy. We hope that it will stimulate reflection and guide the clinician toward appropriate use of humorous interventions. Historical highlights of the topic will be presented. Then a practical definition of therapeutic humor and the main theories about humor will be reviewed. We will also discuss the probable mechanisms of action explaining the efficacy of humor in psychotherapy, as well as potential risks and benefits of its use. We will try to determine different factors influencing the patient's receptivity to humor. Subsequently, a classification of humor will be proposed, followed by a description of selected types of humor often used in therapy, with clinical cases as examples.

  2. Risky business: When humor increases and decreases status.

    Bitterly, T Bradford; Brooks, Alison Wood; Schweitzer, Maurice E

    2017-03-01

    Across 8 experiments, we demonstrate that humor can influence status, but attempting to use humor is risky. The successful use of humor can increase status in both new and existing relationships, but unsuccessful humor attempts (e.g., inappropriate jokes) can harm status. The relationship between the successful use of humor and status is mediated by perceptions of confidence and competence. The successful use of humor signals confidence and competence, which in turn increases the joke teller's status. Interestingly, telling both appropriate and inappropriate jokes, regardless of the outcome, signals confidence. Although signaling confidence typically increases status and power, telling inappropriate jokes signals low competence and the combined effect of high confidence and low competence harms status. Rather than conceptualizing humor as a frivolous or ancillary behavior, we argue that humor plays a fundamental role in shaping interpersonal perceptions and hierarchies within groups.

    At present, selection of procedures for inservice inspection has to take into account the legal basis, i.e. the existing regulatory codes, and the practical aspects, i.e. experience and information obtained by the general, initial inservice inspection or performance data obtained by the latest, recurrent inspection. However, regulatory codes are being reviewed to a certain extent in order to permit integration of technological progress. Depending on the degree of availability in future, of inspection task-specific, sensitive and qualified NDE techniques for inservice inspections (`risk based ISI`), the framework of defined inspection intervals, sites, and detection limits will be broken up and altered in response to progress made. This opens up new opportunities for an optimization of inservice inspections for proof of component integrity. (orig./CB) [Deutsch] Zur Zeit muss sich die Auswahl der Pruefverfahren an den gueltigen Regelwerken und, da es sich um wiederkehrende Pruefungen handelt, an der Basispruefung bzw. der letzten wiederkehrenden Pruefung orientieren. Jedoch vollzieht sich zur Zeit eine Oeffnung der Regelwerke, mit der man auch der Weiterentwicklung der Prueftechniken Rechnung traegt.

Damit ergeben sich neue Moeglichkeiten fuer eine Optimierung der WKP zum Nachweis der Integritaet des Bauteils. (orig./MM)

Heterosexual participants (n = 224 imagined the pursuit of either a desired short-term or long-term relationship, indicated the extent to which they would produce positive and negative humor, and reported how their own interest would change in response to the imaginary target’s use of positive or negative humor. Results revealed that individuals are strategic in their humor production as a function of relational motives. Individuals produced positive humor in both contexts but limited their use of negative humor when pursuing a long-term relationship. The target’s positive humor increased individuals’ attraction, especially women’s, and although negative humor boosted attraction, it did not boost attraction more for short-term than long-term relationships. Findings extend a trait-indicator model of humor and their implications are discussed in light of other theoretical perspectives.

    The way individuals use humor to interact interpersonally has been associated with general personality, depression, and suicidality. Certain humor styles may moderate the risk for suicide ideation (SI) in individuals who are high in specific risk factors (e.g., thwarted belongingness, perceived burdensomeness). Previous research suggests a relationship between humor styles and borderline personality disorder (BPD) and an increased risk of suicidality and suicide completion in individuals with BPD. Participants (n =176) completed measures of BPD traits, SI, and humor styles. It was hypothesized that BPD traits would be positively correlated with negative humor styles and negatively correlated with positive humor styles, and that humor styles would significantly moderate BPD traits and SI. Results showed that BPD traits were negatively correlated with self-enhancing humor styles and positively correlated with self-defeating humor styles, but that they were not significantly correlated with affiliative or aggressive humor styles. Bootstrapping analyses demonstrated that the affiliative, self-enhancing, and self-defeating humor styles significantly moderated BPD traits and SI, while the aggressive humor style did not.

    To test whether appreciation of humor might be a non-motor function affected by Parkinson's disease (PD). Thirty-nine PD patients and 38 healthy controls participated in this study. Appreciation of humor and effect of the presentation method utilized were assessed. Sense of humor was evaluated by the sense of humor questionnaire (SHQ-6). Humor appreciation was tested using three methods of presentation: videos, audio sketches and pictorial cartoons, each portraying both obvious and non-obvious humor content. Depression, anxiety, cognition, disease severity and quality of life were measured by standardized questionnaires and correlated with humor outcomes. Patients with PD rated humor content lower than controls on every method of presentation as well as on the SHQ-6 (p = 0.004). The greatest between-group difference was noted when the material was presented visually via pictorial cartoons (p < 0.0001). In addition, obvious humor content was rated higher than non-obvious content by the PD group in all three presentation methods (p < 0.05). The degree of depression and anxiety did not influence these results. Patients with PD have a decreased sense of humor compared to healthy controls. Utilizing audio methods of presentation and humor in an obvious mode appears to be the preferred approach for eliciting responses to humor in a PD population. Copyright © 2011 Elsevier Ltd.

    Full Text Available Background: The central goal of palliative care is to optimize the quality of life of patients suffering from life-limiting illnesses, which includes psychosocial and spiritual wellbeing. Research has demonstrated positive correlations between humor and laughter with life satisfaction and other aspects of wellbeing, and physiological symptoms can be improved by humorous stimuli.Objectives: The aim of this review is to evaluate humor interventions and assessments that have been applied in palliative care and to derive implications for future research.Methods: A systematic review of four databases identified 13 included studies. Criteria for inclusion were peer-reviewed English-language studies on humor interventions or assessments in a palliative care context.Results: Two studies on humor interventions and 11 studies on humor assessment were included in the systematic review. Most of these studies were about the patients' perspective on humor in palliative care. Findings showed that humor had a positive effect on patients, their relatives, and professional caregivers. Humor was widely perceived as appropriate and seen as beneficial to care in all studies.Conclusions: Even though humor interventions seem to be potentially useful in palliative care, descriptions evaluating their use are scarce. Overall, research on humor assessment and interventions in palliative care has remained limited in terms of quantity and quality. More research activities are needed to build a solid empirical foundation for implementing humor and laughter as part of regular palliative care activities.

    Due to stricter efficiency legislation for electrical machines, it becomes increasingly important to predict a motor's performance with regard to start and operational behaviour correctly. In consequence of the higher efficiency required for electrical machines, permanent magnet synchronous machines become an interesting alternative also for motors with direct on-line starting. This paper describes a method to calculate these motor's behaviour reliably and accurately based on a combined analytical and numerical approach developed at the Institute for Drive Systems and Power Electronics of Leibniz Universitaet Hannover.

    This two-step method described here for the determination of the total carbon-14 content in saturated salt solutions is divided in the analysis of the carbon-14 in the evaporable and the non-evaporable fraction. After driving off the inorganic carbon by acidification, the volatile carbon compounds and volatile decomposition products follow with rising temperature inside the sample vessel in a mild stream of oxygen to a tube furnace equipped with CuO catalyst for oxidizing the carbon compounds to CO{sub 2} at a temperature of 800 C. Water is condensed out with an intensive condenser and the released CO{sub 2} is absorbed in a wash bottle filled with sodium hydroxide. Similarly, an aliquot of the evaporation residue is put in the first zone of the tube furnace during the second step of the analysis. After heating the catalyst in the second zone of the furnace to 800 C the residue is heated stepwise to 800 C. By proceeding in this way, the non-volatile compounds are decomposed or oxidised in the oxygen stream and finally completely oxidized by the aid of the catalyst. The released CO{sub 2} is again absorbed in another wash bottle. The carbonate of each fraction is then precipitated as BaCO{sub 3} separately. Finally, the precipitate is washed, dried, finely grounded and covered with toluene scintillation cocktail for measurement in a LSC. The detection limit is about 0,2 Bq/l for a sample volume of 250 ml.

    The aim of this study was to summarize the actual status for carbon capture, transport and storage for CO{sub 2} emissions from power stations. Special interest was given to the implications from the introduction of carbon capture and storage in power stations on the efficiency, emissions and cost for electricity generation. In the beginning a detailed analyses of the national, European and international activities in this field have been conducted. The analysis focussed on the identification of main actors and the different co-operation of actors. To do so, the available literature has been studied and analysed with a bibliometric approach, which has taken also presentations at national and international conferences into account. In a second step a technical analysis has been undertaken for the three main routes for carbon capture (pre-combustion capture; post-combustion capture, oxy-fuel combustion) with a special emphasis on the impact to the Environment. Truck, ship and pipeline transport have been analysed as means for transporting the CO{sub 2} from the power station to the storage site. In addition the different storage options for a secure long term storage of the captured CO{sub 2} are studied in the report. Special attention was given to the storage options in gasfields and saline aquifers which will be the most promising options in Germany. The report gives an actual overview on the status of carbon capture and storage in the world. It therefore supports the decision making process when introducing this new technology, taking into account the environmental effects. (orig.)

    According to the German act ''Biokraftstoff-Nachhaltigkeitsverordnung'', biofuels must show a CO{sub 2eq}-reduction compared to the fossil reference fuel (83.8 g CO{sub 2eq}/MJ{sub fuel} /Richtlinie 98/70/EG/) of 35 % beginning with 2011. In new plants, which go into operation after the 31.12.2016 the CO{sub 2eq}-savings must be higher than 50 % in 2017 and higher than 60 % in 2018 /Biokraft-NachV/. The biofuels (methyl ester of rapeseed, bioethanol and biomethane) considered in this study do not meet these requirements for new plants. To comply with these rules new processes must be deployed. Alternative thermochemical generated fuels could be an option. The aim of this work is to evaluate through a technical, ecological and economic analysis (Well-to-Wheel) whether and under what conditions the thermochemical production of Fischer-Tropsch-diesel or -gasoline, hydrogen (H{sub 2}) and Substitute Natural Gas (SNG) complies with the targets. Four different processes are considered (fast pyrolysis and torrefaction with entrained flow gasifier, CHOREN Carbo-V {sup registered} -gasifier, Absorption Enhanced Reforming (AER-) gasifier). Beside residues such as winter wheat straw and residual forest wood, wood from short-rotation plantations is taken into account. The technical analysis showed that at present status (2010) two and in 2050 six plants can be operated energy-self-sufficient. The overall efficiency of the processes is in the range of 41.5 (Fischer-Tropsch-diesel or -gasoline) and 59.4 % (H{sub 2}). Furthermore, it was found that for 2010, all thermochemical produced fuels except the H{sub 2}-production from wood from short-rotation plantations in decentralised or central fast pyrolysis and in decentralised torrefactions with entrained flow gasifier keep the required CO{sub 2eq}-saving of 60 %. In 2050, all thermochemical produced fuels will reach these limits. The CO{sub 2eq}-saving is between 72 (H{sub 2}) and 95 % (Fischer-Tropsch-diesel or -gasoline). When the production costs of the thermochemical produced fuels for 2010 are compared, it becomes evident, that they are not competitive with fossil fuels. The range of costs at the petrol station are between 27.1 (Fischer-Tropsch-diesel- or -gasoline) and 70.7 Euro{sub 2010}/GJ{sub fuel} (H{sub 2}). With rising CO{sub 2eq}-costs as well as crude oil and natural gas prices future prospects are getting better for the thermochemical produced fuels.

    A processs for obtaining generator gas from mainly non-fossil waste materials proposes first that these waste products should be changed to pyrolysis coke after being mechanically reduced in size and only then should this coke be introduced into the actual gas reactor. In order to carry out this process, a pyrolysis tube separate from the reactor is used, with a gas-heated double jacket, gas guide pockets in the tube crossection and a mechanical infeed device for the granulate to be pyrolysed in the form of a push rod with a connected supply duct and a guide part for the pyrolysis coke into the reactor.

    Load dependent conduction and switching losses during operation heat up power semiconductor devices. They this way age; lifetime can be limited e.g. by bond wire lift-off or solder fatigue. Components thus need to be dimensioned in a way that they can be expected to reach sufficient reliability during system lifetime. Electromobility or new applications in electric transmission and distribution are demanding in this respect because of high reliability requirements and long operation times. (orig.)

    Currently renewable raw materials are being used in full scale biogas plants as co-substrates. Using grass silage frequently caused technical problems till now. Within the framework of this project, a process to digest grass silage as a single substrate is being developed. An intermittently operating two-stage process is used. As far as the degree of degradation and methane yields are concerned, good and promising results have been achieved. (orig.)

    The invention refers to a process for the manufacture of a fuel catalyst made of tungsten carbide for the direct generation of electrical energy by the oxidation of hydrogen, formaldehyde or formic acid in electrochemical fuel cells. Tungsten carbide is obtained by carburisation of tungsten or tungsten oxide by carbon monoxide. The steps of the process are as follows: dissolving the commercial-quality tungstic acid in ammonium hydroxide; precipitating the tungstic acid with concentrated hydrochloric acid; drying in a vacuum and then heating to 200/sup 0/C to remove the water of crystallisation forming tungsten trioxide; and mixing the tungsten trioxide with zinc powder and heating to 600/sup 0/C. The zinc oxide is dissolved with hydrochloric acid after cooling. The finely divided tungsten obtained in this way is converted with carbon monoxide in a quartz tube at 700/sup 0/C.

    An increase in the activity of electrodes containing tungsten carbide for a low-temperature fuel cell with sulfuric acid as electrolyte can be achieved, if one operates the electrodes for a few hours (5-20 h) in the presence of hydrogen and a means of reduction (formaldehyde, hydrazene) in a voltage range of between +500 and +800 mV (relative to the H/sub 2/ electrode). A corrosion resistant layer is formed, which is assumed to have the composition WC/sub X/O/sub y/H/sub z/.

    2000-07-01

    In this thesis, the results of experimental research work on global bearing behaviour with respect to the existing theoretical basis are systematically analysed for the evaluation and interpretation of measuring results. Among other things, the geometry of the pipeline route, the compactness of the backfilling material and the temperature dependence are considered. The mutual influence of friction and bedding resistances in the region of bends could not yet be determined for a local analysis by existing numerical models. This requires the determination of the induced stress distribution on the pipe perimeter due to lateral displacement of the pipe. The influence is therefore described by a numerical consideration of relative displacements between the pipe and the surrounding soil. Ultimately, relative displacements are verified on the basis of our own complementary results from experimental research carried out in a laboratory for soil mechanics with specially designed test equipment. The global analysis of bearing loads and displacements is done with a numerical model, in which the plastic jacked pipe is idealized as a beam, and the effect of the soil is idealized by spring elements with non-linear force displacement characteristics. An existing numerical model is extended with regard to the new findings and while taking vertical displacements into account. It is used for numerical simulations of selected tests on the global bearing behaviour of underground district heating pipelines which were carried out as part of the research cooperation project. Apart from a good correspondence between calculated results and test results this also provides a plausible description of interrelations. At the same time, however, it also makes itclear that further research is necessary. This thesis provides a contribution to the validation of recent methods for the calculated modelling of the interaction between a district heating pipeline and the subsoil on the basis of experimental research results. This validation is a requirement for the evaluation of the quality of numeric models and is intended to strengthen the users' confidence in the calculated solution. (orig.)

    The X-ray converter serves for application in medical diagnostics. For the cathode system of the converter a system based on low-pressure ionography is suited making use of the X-ray photoelectric emission. The electrodes of the cathode system consist of double-layer films with two external conduction layers and an insulator in between. As an auxiliary voltage can be applied between the individual layers the field gradient in the holes may be adjusted, thus increasing the quantum yield.

    2005-07-01

    A block structured method for the simulation of the viscous flow around complex configurations is presented. The computational domain is discretized with overlapping meshes. The meshes are composed of individually created grids for the components of a configuration and an automatically generated Cartesian background grid. The background grid is a multi-block mesh with hanging grid nodes, which is adapted to the cell size of the component grids. The cells of the background grid can be cubes or cuboids. The overlapping grid approach simplifies the generation of block structured grids significantly. The flow computations are performed with a Navier-Stokes solver. The Chimera capabilities of the solver are extended by methods for the computation of interpolation coefficients and global forces in case of grid overlap on body surfaces. Additionally, a flux conservative boundary condition for the hanging grid nodes is implemented. The consistency and accuracy of the methods is proved by grid refinement studies. Validation test cases include a three element airfoil, a helicopter fuselage and an airplane in landing configuration. Numerical results obtained for Chimera meshes as well as conventional grids agree very well. The agreement with wind tunnel experiments is good. The computational costs for Chimera computations are slightly higher than for conventional grids. (orig.)

    The highly volatile heavy metal mercury is deemed to be very toxic. There exist a lot of natural as well as anthropogenic sources for the pollution of the environment with mercury such as the coal-fired power generation, the electrolytic production of chlorine, the cement burning including the release of mercury from the cement raw meal, the waste incineration and the artisanal production of gold by amalgamation with liquid mercury. The authors of the contribution under consideration report on new procedures for the reduction and capture of mercury emissions in the exhaust gas treatment. The bromine supported precipitation of mercury in the exhaust gas treatment is an efficient and economic process which takes account of the future requirements of lower limit values for mercury. Simultaneously, a new measurement technique for a continuous capture of mercury with new standards on detection sensitivity, accuracy and reliability in connection with a more simple and cost-effective maintenance is developed. The bromine supported precipitation as well as the continuous capture of mercury are trendsetters and are actually the best available technologies for the reduction of mercury emissions.

    Using survey investigations for enterobacteriaceae, coliforms, salmonella, faecal streptococci, f-specific bacteriophagi, enteric virus and parasitic developmental studies the epidemic-hygienic consistency of crude and treated sludges from 24 conventionally operated sewage treatment plants was determined. The results of these studies also provided information about the frequency of occurrences of potential indicator organisms. The microorganisms found were examined for their temperature and ph-resistance to check their suitability as epidemic-hygienic indicators. In this fashion the following parameters were found which can serve for the epidemic-hygienic evaluation of sewage sludge: According to results of laboratory studies, sewage sludge can be considered harmless (1) if it contains not more than 1000 entero bacteriaceae/g, (2) if it contains no salmonella and (3) if it contains no contagious worm eggs. These parameters according to results of laboratory studies also apply to enteric viruses. The parameters also serve in concluding examinations to check some of the practically operated, generally accepted decontamination processes with respect to their epidemic-hygienic efficiency. In this respect it was ascertained that, if properly operated, the processes are basically able to produce epidemically and hygienically harmless sewage sludge. (orig./EF).

    By the experiments described in this report it was examined in 14 different spices to which extent measurements of thermoluminescence intensity of up to 300/sup 0/C are suitable for detecting treatment with ionizing radiation. The optimal weight of each spice was first determined for a later investigation of the dependence of thermoluminescence intensity on dose and postirradiation storage. In most spices, radiation treatment is detectable as long as after a storage period of over 2 months. In general it may be stated that thermoluminescence measurement is a reliable method for detecting radiation treatment in supplement to chemiluminescence measurement.

    The desired ecological goal is the efficient use of a natural byproduct resulting from the cultivation of forests and the maintenance of hedgerows. Since present expenditure is quite high, rational processing techniques are necessary. The entire process is being investigated within the framework of a project promoted by the Deutsche Bundesstiftung Umwelt (DBU), in co-operation with partners from the industrial and agricultural service sectors. Firstly, the vegetation, amongst which the wood of hedgerows ranks, is characterised. The hedgerows grow on earthen walls and consist of numerous types of wood. They are cut after 10-12 years in order to promote a dense and varied regeneration, facilitating their ecological function. This thesis develops and outlines solutions to be utilised in the collection and reduction (i.e. cutting/chopping) of broad swaths of biomass. Owing to earlier observations, various concepts within the co-operative are being implemented, with an aspect to the examination of processing techniques. (orig.)

    For the declaration of the nuclide-inventory of bituminous waste there are currently no standardized sampling-, dissolving- and analysis methods such as for cemented waste, resins and sludge is the case. The aim of this project was to develop a method for the destructive sampling and subsequent radionuclide separation and declaration for the characterization of bituminized waste. The qualitative and quantitative results of non-destructive measurement methods (segmented gamma scanning in combination with digital radiography and gamma transmission computed tomography) are compared with results from destructive analysis. The project involves: - the development of a routine method for sampling bituminized 200-L-waste containers, exemplarily applied to real drums with bituminized waste. - the development of destructive treatment and preparation methods for the obtained bitumen samples with subsequent analysis for: - Alpha emitters, e.g. Pu-, Am- and Cm-isotopes, - Beta/Gamma emitters, e.g. Co-60, Cs-137, - pure Beta emitters, e.g. Sr-90. - Comparison of the results from destructive and non-destructive methods.

    Until the 1980s, bitumen was used as a conditioning agent for weak to medium radioactive liquid waste. Its use can be ascribed mainly to the properties that indicated that the matrix was optimal. However, fires broke out repeatedly during the conditioning process, so that the method is meanwhile no longer permitted in Germany. There are an estimated 100 waste packages held by the public authorities in Germany that require a supplementary declaration. In contrast to the common matrices, such as for example resins or sludges, there is still no standardized technology for taking samples and subsequently determining the radio-nuclide for bitumen. Aspects, such as the thermoplastic behaviour, make determining the nuclide inventory more difficult in bituminized waste packages. The development of a standardized technology to take samples with a subsequent determination of the radio-nuclide analysis is the objective of a project funded by the BMBF. Known, new methods, specially developed for the project, are examined on inactive bitumen samples and then transferred to active samples. At first non-destructive methods are used. The resulting information forms an important basis to work out and apply destructive strategy for sampling and analysis. Since the project is on-going, this report can only address the development of the sampling process. By developing a sampling system, it will be possible to take samples from an arbitrary selected location of the package across the entire matrix level and thus gain representative analysis material. The process is currently being optimized. (orig.)

    The development of the 'Direct Flame Impingement (DFI)-Oxyfuel' process - in which an oxyfuel (oxygen-fuel) flame impinges directly on the material to be heated - represents a further development of furnace technology for continuous strip lines. With assistance from the cooperation partner Linde, the process was used on a hot-dip galvanizing line for the first time at ThyssenKrupp Steel's Finnentrop plant. Right from the start it produced outstanding results in terms of increased throughput, product quality, plant quality and energy efficiency and thus also a reduction in direct CO{sub 2} emissions. In the meantime, this technology also is being used at an additional strip galvanizing and aluminizing facility in the Duisburg-Bruckhausen plant. (orig.)

    In the monitoring of air for /sup 14/C and /sup 3/H the necessary sensitivity cannot be achieved by direct measurement, but only through continuous sampling and scintillation spectroscopy. The two radionuclides are separated from each other at the time of sampling. In addition, by a catalytic reaction over CuO at 600/sup 0/C, a differentiation is achieved between tritiated atmospheric water vapor (HTO), /sup 14/CO/sub 2/ and other isotopically labeled substances contained in the air. Tritium is obtained in the form of water and /sup 14/C as Na/sub 2//sup 14/CO/sub 3/. Radioactivity is measured in a scintillation spectrometer. For tritium this method has a detection limit of 0.8 pCi/m/sup 3/ or air, and for C/sup 14/ 0.6 pCi/m/sup 3/ of air. These values correspond to 15 to 30% of the mean background concentration for HTO and /sup 14/CO/sub 2/ observed up to the present.

    The test procedure for thermo-catalytic explosion alarms for the remote measurement of the methane concentration was changed, so that the readiness of the explosion alarm to operate or faults in it could be measured remotely above ground, without the use of named gas mixtures or master gas analysis equipment. The maximum output signal of indicators is determined simultaneously with switching on the indicators and applying the voltage to the sensors, and its dynamic response characteristic is then measured.

    According to the invention, methane is converted into hydrocarbons with oxygen with high selectivity. This is done in the presence of a catalyst fluidized in a fluidized bed - preferably lead oxide or a mixture of this with antimony oxide - at temperatures between 600 and 800/sup 0/C and at oxygen partial pressures preferably below 0.1-0.2 bar. The ratio of methane partial pressure to oxygen partial pressure should be greater than 2 to 5 if possible. The reactor is operated with gas feedback, in order to raise the selectivity even more.

    ] Meridianstroemungsverfahren werden aufgrund ihres geringen Bedarfs an Rechenzeit zur schnellen Simulation des Betriebsverhaltens von Turbomaschinen eingesetzt. Um dieser Aufgabe bei der Auslegung des Turbinenteils einer Gasturbine gerecht zu werden, muessen die Verfahren sowohl alle wesentlichen stroemungsmechanischen Einfluesse als auch die Einfluesse moderner Systeme zur Bauteilkuehlung beruecksichtigen. Die vorliegende Arbeit befasst sich mit der Modellierung von Sekundaerstroemungseinfluessen, radialen Transportprozessen und Kuehlungseinfluessen in einem auf der Methode der Finiten-Elemente basierenden Meridianstroemungsverfahren. Zur Beruecksichtigung der Einfluesse komplexer Kuehlungssysteme koennen beliebige Konfigurationen von konvektiver Kuehlung, Ausblasung an den Schaufelhinterkanten, Filmkuehlung sowie Ausblasung an Nabe und Gehaeuse vorgegeben werden. Der Mischungsprozess zwischen Hauptmassenstrom und Kuehlluft wird mit Hilfe vereinfachter Bilanzgleichungen berechnet. Massenstromaenderungen werden entweder durch Aenderung der Definitionsgleichungen der Stromfunktion oder im Fall von Ausblasungen in den Randzonen durch geaenderte Randbedingungen an den Seitenwaenden beruecksichtigt. Um bei einem vorgegebenen Druckverhaeltnis den Massenstrom berechnen zu koennen, wird eine Druckregelung implementiert. Die Druckregelung passt den Massenstrom waehrend der Berechnung an das geforderte Druckverhaeltnis an. Die Kontinuitaetsgleichung ist zu jedem Zeitpunkt der Berechnung erfuellt, wodurch die Rechnung beschleunigt wird. Zur Ueberpruefung des Verfahrens wird eine 1,5-stufige Versuchsturbine mit lokaler Kuehlgasausblasung vor der Beschaufelung sowie der Turbinenteil der Hochtemperatur-Gasturbine V84.3 der Firma Siemens AG (KWU) nachgerechnet. Die Hochtemperatur-Gasturbine wird durch eine Kombination von Konvektionskuehlung und Hinterkantenausblasung gekuehlt. Die berechneten Stroemungsgroessen zeigen fuer beide Maschinen eine gute Uebereinstimmung mit experimentellen Daten bzw

  14. Humor and Laughter may Influence Health. I. History and Background

    Full Text Available Articles in both the lay and professional literature have extolled the virtues of humor, many giving the impression that the health benefits of humor are well documented by the scientific and medical community. The concept that humor or laughter can be therapeutic goes back to biblical times and this belief has received varying levels of support from the scientific community at different points in its history. Current research indicates that using humor is well accepted by the public and is frequently used as a coping mechanism. However, the scientific evidence of the benefits of using humor on various health related outcomes still leaves many questions unanswered.

    The benefits of humor in reducing anxiety were investigated in a laboratory study, in which subjects were falsely led to believe that they would receive a shock in 12 min. Participants were 53 undergraduate students with either high or low sense of humor as measured by the Situational Humor Response Questionnaire of Martin and Lefcourt (1984). During the anticipatory period, subjects listened to either a humorous tape, a nonhumorous tape, or no tape. Dependent variables were repeated measures of self-reported anxiety, heart rate, and zygomatic facial activity. Anxiety increased over the anticipatory period, as predicted. A significant interaction between condition and time indicated that subjects from the humor condition consistently rated themselves as less anxious and reported less increase in stress as the shock approached. A three-way interaction concentrating on the final 3 min. indicated a tendency for subjects with low sense of humor to have higher heart rates in the no-tape condition than in the humorous or nonhumorous tape conditions. Analysis for zygomatic activity indicated more smiling by subjects with high sense of humor and by subjects in the humor condition. Also, the humorous tape elicited more smiling by subjects with high sense of humor.

    This study assessed the concurrent and prospective (fall to spring) associations between four different humor styles to assess the degree to which stable friendships are characterized by similarity, and to assess whether best friends' humor styles influence each other's later use of humor. Participants were aged 11-13 years, with 87 stable, reciprocal best friend dyads. Self-report assessments of humor styles were completed on both occasions. Results indicated that there was no initial similarity in dyads' levels of humor. However, dyads' use of humor that enhances interpersonal relationships (Affiliative humor) became positively correlated by spring. Additionally, young people's use of this humor style was positively associated with their best friend's later use of the same. No such effects were present for humor which was aggressive, denigrating toward the self, or used to enhance the self. These results have clear implications for theories of humor style development, highlighting an important role for Affiliative humor within stable friendship dyads. Copyright © 2015 The Authors.

  17. Mathematics and Humor: John Allen Paulos and the Numeracy Crusade

    Directory of Open Access Journals (Sweden)

    Paul H. Grawe

    2015-07-01

    Full Text Available John Allen Paulos at minimum gave the Numeracy movement a name through his book Innumeracy: Mathematical Illiteracy and Its Consequences. What may not be so obvious was Paulos’ strong interest in the relationship between mathematics and mathematicians on the one hand and humor and stand-up-comedian joke structures on the other. Innumeracy itself could be seen as a typically mathematical Gotcha joke on American culture generally. In this perspective, a Minnesotan acculturated to Minnesota-Nice Humor of Self-Immolation Proclivities (SImP looks at the more raw-boned, take-no-prisoners humor style Paulos outlined in Mathematics and Humor and implemented in Innumeracy. Despite the difference in humor styles, there is much to applaud in Paulos’ analysis of the relationship between certain types of humor and professional interests of mathematicians in Mathematics and Humor. Much humor relies on the sense of incongruity which Paulos’ claims to be central to all humor and key to mathematical reductio ad absurdum. Mathematics is rightfully famous for a sense of combinatorial playfulness in its most elegant proofs, as humor often relies on clashing combinations of word play. And a great range of mathematical lore is best understood within a concept of a sudden drop from one sense of certainty to another (essentially a Gotcha on the audience. Innumeracy repeatedly exemplifies Gotchas on the great unwashed and unmathematical majority. Extensive empirical evidence over the last quarter century allows us to synthesize these Paulos observations into the idea that inculcated mathematical humor has strong propensities to complex Intellectual, Advocate, and Crusader humor forms. However, the Paulos humors do not include the Sympathetic Pain humor form, the inclusion of which may increase teaching effectiveness.

  18. The Effect of Context (Humorous vs. Non-humorous on Vocabulary Acquisition and Retention of Iranian EFL Learners

    2012-11-01

    Full Text Available For almost four decades, ESL/EFL scholars have been trying to find which learning type, contextualized vs. decontextualized, leads to better vocabulary acquisition and retention. In an attempt to solve this problem, this study tried to examine the possible effectiveness of using humorous context on vocabulary acquisition and retention. Another issue that was undertaken in the present study was comparing the efficiency of contextualized and decontextualized vocabulary learning and retention. For this purpose, 58 Iranian EFL learners were categorized into 3 groups: a humorous, b non-humorous, and c decontextualized. The findings were analyzed using one-way ANOVA and Tukey post hoc test. As the results revealed, the participants in decontextualized group outperformed the participants in both humorous and non-humorous groups. However, it should be noted that the performance of humorous group was significantly better than the performance of non-humorous group.

    Wastes from three different types of waste treatment facilities (slag from a municipal waste incineration plant, slag granules from a pilot plant combining carbonization and incineration, mechanical and biological treated wastes) were examined to determine their hazard potential to different waters sites. The process temperature is seen to be the main difference between the three treatment processes. The wastes were extracted with water according to the German standard DIN 38414 S 4 and additionally at a constant pH value of 4. The leachates were investigated in a battery of aquatic bioassays and characterised physically and chemically. Every leachate revealed in a toxic effect at least in one test. The toxicity of the leachates prepared at a pH of 4 was significantly higher than the toxicity of the leachates prepared by extraction with water without pH adjustment. The leachates of the slag granules showed the lowest toxicity. On the basis of these experimental results, a scheme to derive Water Hazard Classes of wastes, which is presented in part II of this publication, was developed. (orig.) [German] Zur Bestimmung der wassergefaehrdenden Eigenschaften wurden die Eluate von Abfaellen/Rueckstaenden aus drei verschiedenen Abfallbehandlungsanlagen untersucht (Schlacke aus einer Abfallverbrennungsanlage (Rostfeuerung), Schmelzgranulat aus einer Versuchsanlage mit kombinierter Verschwelung und Hochtemperaturverbrennung sowie biologisch-mechanisch behandelter Abfall). Ein wesentlicher Unterschied dieser drei Verfahren liegt in der Behandlungstemperatur. Die Rueckstaende wurden nach DIN 38414, Teil 4 sowie bei einem konstant eingestellten pH-Wert von 4 eluiert. Die Eluate wurden mit verschiedenen aquatischen Biotests untersucht sowie physikalisch-chemisch charakterisiert. Dabei zeigte sich, dass jedes untersuchte Eluat in mindestens einem Test eine toxische Wirkung aufwies; die Toxizitaet der bei saurem pH-Wert durchgefuehrten Elutionen war deutlich erhoeht.

    The project investigated non-toxic additives for production of ice slurry. Ice slurry is an environment-friendly refrigerant that is increasingly used as a substitute for conventional refrigerants. In view of rising energy prices and an impending tax on climate-relevant refrigerants, ice slurry may soon be used for chilling of food in supermarkets. For this, ice slurry of about 0 C is required for normal cooling and of about -25 C for deep freezing. A very fine-grained, pumpable ice slurry is obtained with glucose as an additive, or with sodium chloride in eutectic concentration with small amounts of ethanol for deep freezing. Ethanol will refine the coarse crystal structure of the eutectic sodium chloride / water mixture and will also reduce the freezing point. Further, the method of primary crystallisation on a crystallised additive was developed. An industrial plant working by this principle will have less disturbances and wear during ice slurry production. [German] Die Projektarbeit befasste sich mit der Untersuchung lebensmittelvertraeglicher Additive zur Herstellung von Eisbrei. Eisbrei gilt als umweltfreundlicher Kaeltetraeger, der zunehmend in verschiedenen Bereichen zur Anwendung kommt und herkoemmliche Kaeltemittel ersetzen kann. Aufgrund steigender Energiekosten sowie einer eventuell anstehenden Besteuerung treibhauswirksamer Kaeltemittel, kann Eisbrei zukuenftig zur Kuehlung von Lebensmitteln in Supermaerkten verwendet werden. Dazu wird Eisbrei mit ca. 0 C fuer die Normalkuehlung, beziehungsweise mit ca. -25 C fuer die Tiefkuehlung benoetigt. Mit Glucose als Zusatzstoff laesst sich ein sehr feinkoerniger und damit pumpbarer Eisbrei fuer die Normalkuehlung erzeugen. Bei der Tiefkuehlung ist Natriumchlorid in einer eutektischen Konzentration mit geringen Mengen Ethanol empfehlenswert. Ethanol verfeinert die grobe Kristallstruktur des reinen eutektischen Natriumchlorid-Wasser-Gemisches und senkt den Gefrierpunkt. Des Weiteren wurde das Verfahren der

    The business purpose of SVZ Schwarze Pumpe is the production of synthesis gas from hydro-carbon-containing waste material and the use of synthesis gas in gas production or energy generation. For synthesis gas production, the techniques of packed-bed pressure gasification (FDV) and entrained-flow gasification (FSV) are used in close interconnection. Process control is such that only inert slags accrue, apart from the final products methanol and gypsum as well as generated energy in the form of electricity, process steam and heat. Currently, the following materials are mainly used in gasification: plastic materials after being subjected to conditioning, industrial and municipal sewage sludge, shredded goods, contaminated used wood, contaminated used oil, oil components obtained from oil/water mixtures, and slurry products. A special in-house know-how for waste oil gasification, and for the combined gasification of solid waste and coal by packed-bed pressure gasification with gradual stepping-up of the waste portion was realized. (orig.) [Deutsch] Der Geschaetszweck des SVZ Schwarze Pumpe besteht in der Herstellung von Synthesegas aus kohlenwasserstoffhaltigen Einsatzstoffen und in der stofflichen und energetischen Nutzung des Wertstoffes Synthesegas. Zur Synthesegasgewinnung werden die Verfahren der Festbettdruckvergasung (FDV) und Flugstromvergasung (FSV) in einer engen verbundwirtschaftlichen Kopplung angewandt. Die Betriebsfuehrung ist so gestaltet, dass neben den Endprodukten Methnaol und Gips sowie erzeugter Energie in Form von Strom, Prozessdampf und Waerme nur noch inerte Schlacken entstehen. Die Haupteinsatzprodukte fuer die Vergasung sind ggw. aufbereitete Altkunststoffe, industrielle und kommunale Klaerschlaemme, Shreddergueter, kontaminiertes Altholz, kontaminierte Altoele, Oelkomponenten, die aus Oel-Wasser-Gemischen gewonnen werden, und Slurry-Produkte.

  3. Experimental sepsis impairs humoral memory in mice.

    Directory of Open Access Journals (Sweden)

    Christian Pötschke

    Full Text Available Patients with sepsis are often immune suppressed, and experimental mouse models of sepsis also display this feature. However, acute sepsis in mice is also characterized by a generalized B cell activation and plasma cell differentiation, resulting in a marked increase in serum antibody concentration. Its effects on humoral memory are not clearly defined. We measured the effects of experimental sepsis on long-term immunological memory for a defined antigen: we induced colon ascendens stent peritonitis (CASP 8 weeks after 2 rounds of immunization with ovalbumin. Four weeks later, the antigen-specific bone marrow plasma cell count had doubled in immunized non-septic animals, but remained unchanged in immunized septic animals. Sepsis also caused a decrease in antigen-specific serum antibody concentration. We conclude that sepsis weakens humoral memory by impeding the antigen-specific plasma cell pool's development, which is not complete 8 weeks after secondary immunization.

  4. Can the use of humor in psychotherapy be taught?

    Despite an abundance of literature detailing the potential benefits of the use of humor in therapy, humor is rarely taught to psychiatric residents as a method of therapeutic intervention. This communication attempts to explain how current understanding of attachment theory and neuroscience may assist psychiatric faculty and supervisors in their teaching of humorous therapeutic interventions. This article reviews and synthesizes the extant literature on the use of humor, as well as recent work in neuroscience, attachment theory, and mentalization. Humor can be conceptualized as an instance of implicit relational knowing and may thus contribute significantly to the therapeutic action of psychotherapy as a subcategory of "moments of meeting" between therapist and patient. However, training residents to use humor in psychotherapy requires more individualized attention in supervision and classroom seminars. Factors such as individual proclivities for humorous repartee, mentalizing capacity, and an authentic interest in adding humor to the session may be necessary to incorporate spontaneous humor into one's technique. New findings from the areas of attachment theory, neuroscience, and right-hemisphere learning are providing potential opportunities for sophisticated teaching of the use of humor in psychotherapy.

    Little is known about humor's use in clinical encounters, despite its many potential benefits. We aimed to describe humor during clinical encounters. We analyzed 112 recorded clinical encounters. Two reviewers working independently identified instances of humor, as well as information surrounding the logistics of its use. Of the 112 encounters, 66 (59%) contained 131 instances of humor. Humor was similarly frequent in primary care (36/61, 59%) and in specialty care (30/51, 59%), was more common in gender-concordant interactions (43/63, 68%), and was most common during counseling (81/112, 62%). Patients and clinicians introduced humor similarly (63 vs 66 instances). Typically, humor was about the patient's medical condition (40/131, 31%). Humor is used commonly during counseling to discuss the patient's medical condition and to relate to general life events bringing warmth to the medical encounter. The timing and topic of humor and its use by all parties suggests humor plays a role in the social connection between patients and physicians and allows easier discussion of difficult topics. Further research is necessary to establish its impact on clinicians, patients, and outcomes. © Copyright 2018 by the American Board of Family Medicine.

    Full Text Available Sam ShusterNewcastle University, Newcastle Upon Type, NE1 7RU, UKAbstract: The response to seeing a man riding a unicycle was reported to be consistently related to the viewer's sex and stage of physical development. To see if this observation was universal, observations of responses were collected from 23 male and 9 female unicyclists aged 15–69 years, with 2–40 years cycling experience across four continents. With two exceptions among men, the findings were the same as those originally reported: children showed interest and curiosity, young girls showed little interest, while adult women showed a kindly, concerned, praising response. By contrast, boys showed physical aggression, which became more verbal, merging in the later teens to the snide, aggressive, stereotyped humorous response shown by adult males, which became less frequent in elderly men. The universality of the response across different individuals, environments, and dates of observation suggests an endogenous mechanism, and the association with masculine development relates this to androgen. The theoretical consequences are discussed. It is concluded that humor develops from aggression in males and is evolutionarily related to sexual selection.Keywords: humor evolution, male aggressive behavior

    The evidence for the effectiveness of humor-based positive psychology interventions (PPIs; i.e., interventions aimed at enhancing happiness and lowering depressive symptoms) is steadily increasing. However, little is known about who benefits most from them. We aim at narrowing this gap by examining whether personality traits and sense of humor moderate the long-term effects of humor-based interventions on happiness and depressive symptoms. We conducted two placebo-controlled online-intervention studies testing for moderation effects. In Study 1 ( N = 104) we tested for moderation effects of basic personality traits (i.e., psychoticism, extraversion, and neuroticism) in the three funny things intervention, a humor-based PPI. In Study 2 ( N = 632) we tested for moderation effects of the sense of humor in five different humor-based interventions. Happiness and depressive symptoms were assessed before and after the intervention, as well as after 1, 3, and 6 months. In Study 2, we assessed sense of humor before and 1 month after the intervention to investigate if changes in sense of humor go along with changes in happiness and depressive symptoms. We found moderating effects only for extraversion. Extraverts benefitted more from the three funny things intervention than introverts. For neuroticism and psychoticism no moderation effects were found. For sense of humor, no moderating effects were found for the effectiveness of the five humor-based interventions tested in Study 2. However, changes in sense of humor from pretest to the 1-month follow-up predicted changes in happiness and depressive symptoms. Taking a closer look, the playful attitude- and sense of humor-subscales predicted changes in happiness and depression for up to 6 months. Overall, moderating effects for personality (i.e., extraversion) were found, but none for sense of humor at baseline. However, increases in sense of humor during and after the intervention were associated with the interventions

    A method of coupling two meteorological models of different scales must meet certain requirements: First, even a big difference in resolution between the two models must not produce disturbances in the smaller-scale model. This means that most nesting approaches are unfit for the purpose. The method presented here is not limited to meteorological models. It can be enhanced without much difficulty to dispersion models taking account of chemical atmospheric reactions, as e.g. in the CTM of the EURAD model or in DRAIS as an enhancement of the KAMM version. [German] Das Ziel dieser Arbeit bestand in der Entwicklung eines geeigneten Kopplungsverfahrens zweier verschiedenskaliger meteorologischer Modelle, das in einem Ein-Weg-Nesting dem kleinerskaligen Modell ermoeglicht, sowohl instationaere superskalige Verhaeltnisse als auch modellinterne kleinraeumige Prozesse miteinander zu verbinden. Im Rahmen des Projektes TFS mussten hierbei entscheidende Bedingungen an das Kopplungsverfahren gestellt werden. Allen voran darf vor allem ein auch grosser Unterschied in der Aufloesung der beiden verschiedenskaligen Modelle keine kuenstlichen Stoerungen im kleinerskaligen Modell produzieren. Somit scheiden die sonst ueblichen Nestingansaetze fuer diesen Fall aus. Das Verfahren ist derart konzipiert, dass es sich nicht auf rein meteorologische Modelle beschraenkt. Eine Ausweitung auf Ausbreitungsmodelle unter Beruecksichtigung chemischer Reaktionen in der Atmosphaere, wie sie etwa im CTM des EURAD-Modells oder im DRAIS als Erweiterung der KAMM-Version zur Verfuegung stehen, stellt keinen allzu grossen Schritt mehr dar.

    Full Text Available The purpose of this study was to examine the role of humor style and motor skills in vulnerability to bullying. 729 adults responded to the Humor Style Questionnaire (HSQ and items retrospectively addressing their motor skills and bullying experiences during childhood. Consistent with recent research, poorer motor skills were associated with a greater extent of having been bullied. An association between stronger motor skills and affiliative humor was found, lending support to a shared biological basis theory underlying social and motor competency processes. Most importantly, being bullied was associated with higher self-defeating humor and lower affiliative humor. This supports earlier theoretical work by Klein and Kuiper (2006 and highlights the role that humor styles play in social interactions that can promote positive peer acceptance and wellbeing.

    A framework for driver task analysis is derived from a model of the drivers information processing. The first step of the procedure (SAFE) is to divide a given driving task (e.g. left turning in a signalised intersection of a certain type) into subtasks. These subtasks are appointed to defined stretches of the road and the time structure of the subtasks is determined. For each subtask an analysis format is used, that organizes different requirements into perception, expectation, judgement, memory, decision and driver action. In a next step, typical driver errors are appointed to the subtasks. Afterwards the information gathered in the analysis procedure is compressed to ratings of the complexity and risk included in each subtask. After the crucial subtasks of a driving task have been determined, a list of those requirements that led to that rating can be compiled. These lists give the potential for aiding the driver e.g. by use of driver assistance systems. (orig.)

    Humor is a complex behavior which includes cognitive, affective and motor responses. Based on observations of affective changes in patients with cerebellar lesions, the cerebellum may support cerebral and brainstem areas involved in understanding and appreciation of humorous stimuli and expression of laughter. The aim of the present study was to examine if humor appreciation, perception of humorous stimuli, and the succeeding facial reaction differ between patients with cerebellar degeneration and healthy controls. Twenty-three adults with pure cerebellar degeneration were compared with 23 age-, gender-, and education-matched healthy control subjects. No significant difference in humor appreciation and perception of humorous stimuli could be found between groups using the 3 Witz-Dimensionen Test, a validated test asking for funniness and aversiveness of jokes and cartoons. Furthermore, while observing jokes, humorous cartoons, and video sketches, facial expressions of subjects were videotaped and afterwards analysed using the Facial Action Coding System. Using depression as a covariate, the number, and to a lesser degree, the duration of facial expressions during laughter were reduced in cerebellar patients compared to healthy controls. In sum, appreciation of humor appears to be largely preserved in patients with chronic cerebellar degeneration. Cerebellar circuits may contribute to the expression of laughter. Findings add to the literature that non-motor disorders in patients with chronic cerebellar disease are generally mild, but do not exclude that more marked disorders may show up in acute cerebellar disease and/or in more specific tests of humor appreciation.

  3. Trait humor and longevity: do comics have the last laugh?

    Four sets of biographical data were analyzed in order to test the hypothesis that the ability to generate humor is associated with longevity. Although steps were taken to ensure that tests had high levels of statistical power, analyses provided very little support for the idea that individuals with a well-developed sense of humor live longer than serious writers and other entertainers. In addition, a subsidiary analysis revealed that those in the business of entertaining others died at an earlier age than those in other lines of endeavor. These findings suggest that researchers should turn their attention from trait humor to the effects of humorous material.

    Humor training has been applied to educational and clinical cases and has been found to be effective, but humor training for individuals with autism is relatively rare. The present study proposed a humor-knowledge and humor-skill training workshop to enhance the humor comprehension and appreciation of individuals with autism and examined the effects of the training. Participants were 20 adolescents with autism and average intelligence (above 70 in WAIS-III). They were randomly divided into experimental and control groups. Both questionnaire of joke comprehension and appreciation and a humor style questionnaire were used as instruments. The results supported the effectiveness of the 15-h training. The comprehension and appreciation of nonsense humor were significantly increased in the experimental group in comparison with the control group, although the incongruity-resolution jokes remained difficult to comprehend. The tendency to use affiliative humor was greater among individuals with autism in the experimental group, suggesting that the appreciation of humor can be learned.

    Although a series of reports on corneal fungal infection have been published, studies on pathogenic mechanisms and inflammation-associated cytokines remain limited. In this study, aqueous humor samples from fungal keratitis patients were collected to examine cytokine patterns and cellular profile for the pathogenesis of fungal keratitis. The aqueous humor samples were collected from ten patients with advanced stage fungal keratitis. Eight aqueous humor samples from patients with keratoconus or corneal dystrophy were taken as control. Approximately 100 μl to 300 μl of aqueous humor in each case were obtained for examination. The aqueous humor samples were centrifuged and the cells were stained and examined under optical microscope. Bacterial and fungal cultures were performed on the aqueous humor and corneal buttons of all patients. Cytokines related to inflammation including IL-1β, IL-6, IL-8, IL-10, TNF-α, and IFN-γ were examined using multiplex bead-based Luminex liquid protein array systems. Fungus infection was confirmed in these ten patients by smear stains and/or fungal cultures. Bacterial and fungal cultures revealed negative results in all aqueous humor specimens. Polymorphonuclear leukocytes were the predominant infiltrating cells in the aqueous humor of fungal keratitis. At the advanced stages of fungal keratitis, the levels of IL-1β, IL-6, IL-8, and IFN-γ in the aqueous humor were significantly increased when compared with control (phumor was associated with fungal keratitis.

    According to research literature, humor inside the staff-patient interaction seems to be significant in the area of forensic mental healthcare. However, existing literature on the subject is limited. Therefore, the aim of this study was to explore the characteristics of the use humor by forensic mental health staff members in interactions with forensic mental health inpatients. The study included 32 forensic mental health staff members, used 307 hours of participant observations, 48 informal interviews, and seven formal semistructured interviews. Outcomes identify four themes concerning the conveyance of power to, from, and between forensic mental health staff and patients as they interact: (a) "the informal use: the human-to-human approach," characterized by an informal use of humor and without any reference to mental health issues; (b) the "formal use of humor: the staff-patient approach," characterized as formal with a view on the patient as mentally ill, unable to understand humor, and with the aim of using humor to prevent conflicts or negative behavior; (c) "protest against requested care: the human-patient approach," characterized by the use of humor as a protest against requested care; and the use of (d) "inadequacy humor: the staff-human approach," characterized by the use of inadequacy-humor referring to, for example, patients' physical features. Recommendations and clinical implications are discussed.

    2017-03-01

    Full Text Available The study reported in this paper aims to analyze the possible strategies used in the subtitling of the first five episodes (season 1 of Friends to render the episodes’ humorous dialogues. It examines the subtitler’s strategies in preserving both the semantic and humorous genes of laughter intended by the original humor. The analysis takes into account the internal and external structures of humors both in the target and source language. Choosing a subtitling strategy involves a decisionmaking process where the internal and external factors come into play and, therefore, rendering humors in a contextually bound medium, such as subtitling, does not necessarily work in the TL environment in a consistent manner. The inconsistency highlights the fact that humors, even those considered universal, are not digested in the same manner across cultures.

    Risikoabschaetzungen ueber die moeglichen gesundheitlichen Auswirkungen von Umweltbelastungen sind moeglichst exakte Abschaetzungen der Schadstoffexposition der Betroffenen unerlaesslich. Zur Durchfuehrung solcher Expositionsabschaetzungen koennen zwei grundlegend unterschiedliche Ansaetze verfolgt werden: Die traditionelle (deterministische) Methode der Expositionsabschaetzung geht von Messwerten einzelner Belastungsparameter (z.B. Schadstoff-Konzentration in der Luft, im Boden etc.) aus und verknuepft diese mit individuellen Einflussgroessen (z.B. Aufnahmerate, Koerpergewicht). Zur Beschreibung der Exposition und damit zur Ableitung des zu erwartenden Risikos wird fuer die in die Berechnung einfliessenden Groessen haeufig jeweils das 95. Perzentil verwendet. Dieses als Punktschaetzung fuer den sog. 'unguenstigen Fall' bezeichnete Verfahren kann eine u.U. unrealistische Ueberschaetzung der Exposition und damit des gesundheitlichen Risikos zur Folge haben. Der probabilistische Ansatz verwendet demgegenueber fuer alle verfuegbaren Parameter deren statistische Verteilungen und verknuepft sie miteinander. Beim Monte Carlo-Verfahren werden entsprechend der Verteilungsfunktionen der eingehenden Parameter Stichproben 'gezogen' und miteinander verknuepft. Mit zunehmendem Stichprobenumfang konvergieren die Simulationsergebnisse schliesslich gegen die gesuchte Expositionsverteilung. Gerade in den fuer die gesundheitliche Bewertung besonders relevanten Randbereichen der Verteilungen liegen zuweilen nur wenige Daten vor. Dies fuehrt zu Ungenauigkeiten in der Expositionsabschaetzung, da deren Qualitaet wesentlich von der Qualitaet, Quantitaet und Repraesentativitaet der vorhandenen Messwerte abhaengt, aus denen die Ausgangsverteilungen bestimmt werden. Dennoch ist bei ausreichender Datenbasis der probabilistische Ansatz der Verwendung von Punktschaetzern zur Expositionsabschaetzung deutlich ueberlegen und sollte daher zunehmend auch Eingang in die Praxis der Risikoabschaetzung

    The aim of the project was to transfer the developed method of laser beam welding of heat treated machining steels of temperature field tailoring on hot crack endangered austenitic Cr-Ni steels and nickel-based alloys. With this method, transient thermal stresses adjacent to the weld are produced by an travelling induction heating so that the hot cracking is prevented during welding. As test materials the austenitic Cr-Ni steel with sulfur additive 1.4305, the Cr-Ni steels 1.4404 and 1.4435 and the nickel-based alloy Udimet 720 were selected. As a result of the research it was shown that a hot crack-free laser welding in the investigated materials using at least three different welding and material-technical approaches is possible.

Mit diesem Verfahren werden waehrend des Schweissens transiente thermische Spannungen neben der Schweissnaht durch eine mitlaufende induktive Erwaermung so erzeugt, dass die Heissrissbildung verhindert wird. Als Versuchswerkstoffe wurden der austenitische Cr-Ni-Stahl mit Schwefelzusatz 1.4305, die Cr-Ni-Staehle 1.4404 und 1.4435 sowie die Nickelbasislegierung Udimet 720 ausgewaehlt.

    Ancient medicine integrated three components: experience (empirical observation), religion/magic and speculations of natural philosophers. The Greek medicine out-achieved medicine of other ancient nations in starting to investigate the true causes of health and diseases and thus laying foundations for the diagnosis, prognosis and treatment. Hippocrates, the most famous physician of the ancient times, made a synthesis of existing philosophical opinions from the point of view of a physician. His 58 writings were preserved in the collection "Corpus Hippocraticum". The most relevant writing in it--"Peri fyseos anthropu" (On the nature of man)--is ascribed to Hippocrates' son-in-law Polybos to whom we are grateful for the ancient humoral-pathological theory. In explaining human organism and its processes the author integrated ancient teachings on 4 basic humors (humoral theory), elements and qualities with observations of manifestations of health and disease. Normal condition (health) was defined as balance between the body fluids (eukrasia) and external environment. If this balance is disturbed, the result is dyskrasia, i.e. disease studied by pathology. According to Hippocrates disease causes can be understood only through empirical study. A man has a power to overcome disease, but to achieve it the right diet is necessary to keep harmony in body fluids of an organism. The role of a physician was just to support the nature. "Prognosis", another writing included in "Corpus Hippocraticum", reflects Hippocrates' understanding of prognosis as a necessary development of diagnosis based on past knowledge (anamnesis) and present observation. Ideas of Hippocrates and his medical school are still valuable and inspiring especially for today's very sophisticated medicine--concept of fighting diseases by natural means: maintaining healthy lifestyle and harmony within the organism, or an effort for perfect understanding of human creature and for humanization of medicine.

    Recently, two forms of virtue-related humor, benevolent and corrective, have been introduced. Benevolent humor treats human weaknesses and wrongdoings benevolently, while corrective humor aims at correcting and bettering them. Twelve marker items for benevolent and corrective humor (the BenCor) were developed, and it was demonstrated that they fill the gap between humor as temperament and virtue. The present study investigates responses to the BenCor from 25 samples in 22 countries (overall N = 7,226). The psychometric properties of the BenCor were found to be sufficient in most of the samples, including internal consistency, unidimensionality, and factorial validity. Importantly, benevolent and corrective humor were clearly established as two positively related, yet distinct dimensions of virtue-related humor. Metric measurement invariance was supported across the 25 samples, and scalar invariance was supported across six age groups (from 18 to 50+ years) and across gender. Comparisons of samples within and between four countries (Malaysia, Switzerland, Turkey, and the UK) showed that the item profiles were more similar within than between countries, though some evidence for regional differences was also found. This study thus supported, for the first time, the suitability of the 12 marker items of benevolent and corrective humor in different countries, enabling a cumulative cross-cultural research and eventually applications of humor aiming at the good.

  15. The evolution of humor from male aggression.

    Shuster, Sam

    2012-01-01

    The response to seeing a man riding a unicycle was reported to be consistently related to the viewer's sex and stage of physical development. To see if this observation was universal, observations of responses were collected from 23 male and 9 female unicyclists aged 15-69 years, with 2-40 years cycling experience across four continents. With two exceptions among men, the findings were the same as those originally reported: children showed interest and curiosity, young girls showed little interest, while adult women showed a kindly, concerned, praising response. By contrast, boys showed physical aggression, which became more verbal, merging in the later teens to the snide, aggressive, stereotyped humorous response shown by adult males, which became less frequent in elderly men. The universality of the response across different individuals, environments, and dates of observation suggests an endogenous mechanism, and the association with masculine development relates this to androgen. The theoretical consequences are discussed. It is concluded that humor develops from aggression in males and is evolutionarily related to sexual selection.

  16. Sildenafil Stimulates Aqueous Humor Turnover in Rabbits

    Sildenafil citrate increases ocular blood flow and accelerates the rate of anterior chamber refilling after paracentesis. The latter effect could have resulted from a reduction in outflow facility or from an increase in aqueous humor (AH) production. In this study, we used scanning ocular fluorophotometry to examine the effects of sildenafil on AH turnover, and thus, AH production in eyes of live normal rabbits. For this, the rate of aqueous humor flow (AHF) was quantified with a commercially available fluorophotometer that measured the rate of fluorescein clearance from the anterior segment, which predominantly occurs via the trabecular meshwork. After ≈ 2 hrs of control scans to determine the baseline rate of AHF, the rabbits were fed 33 mg of sildenafil and allowed ≈ 45 min for the drug to enter the systemic circulation. Thereafter, fluorescence scans were retaken for an additional 90–120 min. Sildenafil ingestion increased AHF by about 36%, from 2.31 μL/min to 3.14 μL/min (PViagra, Revatio), stimulates AHF in rabbits. Our results seem consistent with reports indicating that the drug dilates intraocular arteries and augments intraocular vascular flow. These physiological responses to the agent apparently led to increased fluid entry into the anterior chamber. As such, the drug might have utility in patients with ocular hypotony resulting from insufficient AH formation. PMID:23562660

    Full Text Available In the developmental literature it has been advanced that young children would not understand the specificity of nonliteral communicative acts. In this article I shall focus on young children’s ability to produce and understand different forms of humor. I shall explore children’s acquisition of the communicative contexts that constitute the background enabling them to perform humorous interactions before being able to analyze them in the terms allowed by a full fledged ToM. I consider that different forms of humor share a number of basic features and that we can draw a continuum from simple forms to sophisticated ones. In particular I shall focus on teasing, a form of humor already present in preverbal infants but also considered as a typical feature of irony. I shall argue that all forms of humor can be described in the terms of a kind of interaction that I propose to call playing with expectations.

    Full Text Available Effects of humor in advertisement published in Colombia were investigated in regards to brands,advertisement, purchase intention, recall and recognition.A simultaneous Classical Conditioning procedure was carried out, using Incongruous, Hostile and Allusivehumor associated to three brands. The procedure was applied to 30 university students. Results revealedthat the three kinds of humor work as unconditioning stimulus, generating positive attitudes towardsadvertisement and brand. Humor influences the purchase intention and recognition, but not the remembranceof brand when compared to neutral advertisement. Incongrous and Hostile Humor generate recognitionand positive attitude towards advertisement and brand. Allusions have a greater effect on purchaseintention than the other ones. Results corroborate the effectiveness of humor as an advertisement tool.

In this article, I focus on young children’s ability to produce and understand different forms of humor. I explore the acquisition of the communicative contexts that enable children to engage in humorous interactions before they possess the capacity to analyze them in the terms afforded by a full-fledged theory of mind. I suggest that different forms of humor share several basic features and that we can construct a continuum from simple to sophisticated forms. In particular, I focus on teasing, a form of humor already present in preverbal infants that is also considered a typical feature of irony.

    2001-03-01

    Full Text Available Nicht nur Fachleute beklagen die mangelnde Qualität der deutschen Filme und Werbespots. Eine Ursache für die mangelnden Erfolge solcher mediatisierten Kommunikation liegt in einer systematischen Interaktionsstörung zwischen der Medienpraxis und Medienforschung. Die aktuelle deutschsprachige Medienwirkungsforschung entzieht sich weitgehend der gebotenen und von Macher/innen erwarteten gesellschafts- und praxisdienenden Aufgabe. Der Hauptgrund hierfür liegt darin, dass die zumeist zugrunde gelegten Forschungsrahmen (conceptual frameworks praxisrelevante Kategorien wie die der Zuschauerperspektive weitgehend ignorieren. Das hier vorgestellte interaktionistische Modell der mediatisierten Kommunikation will deshalb als Forschungsrahmen den Blick auf Übersehenes richten. Darüber hinaus soll dieses Modell auch für Praktiker als Prüfschema zur Mediaplanung dienen, mediatisierte Kommunikation - gemessen am eigenen Anspruch - kalkulierbarer und damit auch erfolgreicher zu machen.

Wesentliche Ergebnisse dieser Untersuchungen waren: Die alleinige Durchfuehrung der Trockenmessung im Rahmen der wiederkehrenden Fachbetriebs- oder Sachverstaendigenpruefungen ist nicht ausreichend. Die Trockenmessung sollte deshalb immer durch eine Pruefung mit realem Kraftstofffluss ergaenzt werden, um Systemfehler zu erkennen, die bei einer simulierten Messung nicht angezeigt werden.

    Full Text Available Objective: The provision of information appears to be an important feature of humor. The present studies examined whether humor serves as an interpersonal signal such that an individual's style of humor is associated with how the individual is perceived by others. Method: We examined this issue across two studies. In Study 1, undergraduate participants (257 targets were rated more positively by their friends and family members (1194 perceivers when they possessed more benign humor styles. In Study 2, 1190 community participants rated the romantic desirability of targets ostensibly possessing different humor styles. Results: Across both studies, our results were consistent with the possibility that humor serves as a signal. More specifically, individuals with benign humor styles (affiliative and self-enhancing humor styles were evaluated more positively than those targets with injurious humor styles (aggressive and self-defeating humor styles. Conclusion: These findings are discussed in terms of the role that humor may play in interpersonal perception and relationships.

    Aqueous humor dynamics was observed in patients treated for glaucoma. Aqueous flow was measured using the radionuclide method of contact application of 22 NaCl and the detection of gamma radiation with external detectors. The sample of 184 eyes was divided into three groups: open-angle glaucoma with therapy, open-angle glaucoma without therapy and angle-closure glaucoma 47 eyes were used as controls. Changes were observed in 22 Na outflow half-time in dependence on the duration of the disease, therapy, intraocular pressUre and changes in the perimeter. The new technique has been fully proven in practice, is a contribution to the diagnosis of glaucoma and an indicator of the compensation of the disease. (author)

    The transformation of all things media and information into a dynamic environment of user access has created what seems infinite possibilities to inform the public in many different ways - as well as seemingly infinite possibilities to confuse. This talk will describe a rather non-conventional collaboration between two different creative cultures and its significance to maintaining scientific accuracy and devising strategies important to audience engagement - among them, humor. While focusing on the award-winning effort ``When Things Get Small'' created by University of California Television producer R. Wargo in collaboration with condensed matter physicist I.K. Schuller and actor Adam J. Smith, with both NSF and private support, the case study provides insight into a model and modes which can be used successfully by other scientists to engage the public in what they do.

    The aim of the paper is to present the Polish adaptation of the Humor Climate Questionnaire (HCQ), designed to measure humor as organizational climate feature. The authors employed back-translation and independent judges method to choose the best version of the translated items. The psychometric properties of HCQ were estimated on the basis of 2 samples: the basic group of employees (N = 217) and the group of employees who had completed the survey twice (N = 55). The results of statistical analyses proved that HCQ is a reliable tool. Explorative Factor Analysis supported the 4-factor structure of the original method's theoretical model. The validity of the subscales is high, Cronbach's α varied from 0.8 to 0.9. The directions and values of intercorrelations between subscales were similar to those of the English version. The Humor Climate Questionnaire is a relatively time-stable tool (r = 0.44-0.74). Polish adaptation is reliable and applicable for cross-sectional studies. The obtained results are comparable to the characteristics of the original version. However, the results of factor analysis show that the data do not fully fit the theoretical model.

    Abstract The study aimed to explore the humor processing elicited through the manipulation of artistic drawings. Using the Comprehension–Elaboration Theory of humor as the main research background, the experiment manipulated the head portraits of celebrities based on the independent variables of facial deformation (large/small) and addition of affective features (positive/negative). A 64-channel electroencephalography was recorded in 30 participants while viewing the incongruous drawings of celebrities. The electroencephalography temporal and spectral responses were measured during the three stages of humor which included incongruity detection, incongruity comprehension and elaboration of humor. Analysis of event-related potentials indicated that for humorous vs non-humorous drawings, facial deformation and the addition of affective features significantly affected the degree of humor elicited, specifically: large > small deformation; negative > positive affective features. The N170, N270, N400, N600-800 and N900-1200 components showed significant differences, particularly in the right prefrontal and frontal regions. Analysis of event-related spectral perturbation showed significant differences in the theta band evoked in the anterior cingulate cortex, parietal region and posterior cingulate cortex; and in the alpha and beta bands in the motor areas. These regions are involved in emotional processing, memory retrieval, and laughter and feelings of amusement induced by elaboration of the situation. PMID:28402573

    Full Text Available Although there are many clinical programs designed to bring humor into pediatric hospitals, there has been very little research with children or adolescents concerning the specific utility of humor for children undergoing stressful or painful procedures. Rx Laughter™, a non-profit organization interested in the use of humor for healing, collaborated with UCLA to collect preliminary data on a sample of 18 children aged 7–16 years. Participants watched humorous video-tapes before, during and after a standardized pain task that involved placing a hand in cold water. Pain appraisal (ratings of pain severity and pain tolerance (submersion time were recorded and examined in relation to humor indicators (number of laughs/smiles during each video and child ratings of how funny the video was. Whereas humor indicators were not significantly associated with pain appraisal or tolerance, the group demonstrated significantly greater pain tolerance while viewing funny videos than when viewing the videos immediately before or after the cold-water task. The results suggest that humorous distraction is useful to help children and adolescents tolerate painful procedures. Further study is indicated to explore the specific mechanism of this benefit.

    It has been proposed that four main styles of humor exist, two which are thought to be adaptive (affiliative, self-enhancing) and two which are thought to be maladaptive (aggressive, self-defeating). Whilst the existence of these four humor styles has been supported in older children, it is suggested that for younger children, self-enhancing and self-defeating humor may develop at a later point. To investigate this further, the current research involved five semi-structured paired interviews with children aged eight to eleven years to explore the use and understanding of self-enhancing and self-defeating humor in this age group. Findings indicated that use of both self-enhancing and self-defeating humor were apparent in some children, but not all. It therefore seems appropriate that attempts to investigate humor in this age group should aim to include all four styles of humor. The current research also demonstrated the value of paired interviews when carrying out this sort of research with children. PMID:27547258

    2012-01-01

    Background In contrast with an early implicit “facilitative hypothesis” of humor, a revised specificity hypothesis predicts that the benefits of humor depend on the specific style of humor used. Information on predictors of these humor styles in turn enhances the ability to predict the effect on well-being. Methods We examined the relationships between interpersonal competence, self-esteem, and different styles of humor, while also examining the contributions of age and gender. Participants (n = 201) aged 18–63 years completed the Rosenberg Self-Esteem Inventory, the Interpersonal Competence Questionnaire, and the Humor Styles Questionnaire, and gave demographic information. Results High self-esteem was associated with higher use of affiliative, aggressive, and self-enhancing humor styles, but lower use of self-defeating humor. High interpersonal competence predicted greater use of affiliative humor, whereas low interpersonal competence predicted greater use of aggressive humor. Further analyses showed that initiation competence predicted affiliative humor (positively) but both initiation competence (positively) and conflict management competence (negatively) predicted aggressive humor. Conclusion The findings that both self-esteem and initiation competence contribute to use of aggressive humor add to knowledge of who is likely to use this potentially harmful humor style. We conclude that a readiness to initiate humorous interactions is not on its own a general and positive attribute contributing to “good” humor. PMID:23180973

    Full Text Available Gender-related humors have their own way of being funny; and this research aims to find out how and why they are funny. For this purpose, both researchers have collected 50 gender cyber humors and analyzed them, first, to decode how their logical mechanism relates to specific linguistic features, and secondly, to uncover how gender stereotyping contributes to the comical effects. The twisting of logic and linguistic ambiguity is analyzed formally using Attardos (2001 General Theory of Verbal Humor (GTVH and supported by gender studies. The findings reveal that the logical mechanism consists of elements of incongruities, and gender stereotyping presents negative stereotypical images. The analysis further shows that some gender stereotypical images ridicule traditional roles of man and woman while others make fun of non-traditional representations. This shift from women only to both men and women as targets of gender humors has been an impact of effective feminist movements.

    2017-07-01

    This project explores the regional phospholipid distribution in porcine vitreous humor, retina, and lens. Matrix-assisted laser desorption mass spectrometry has been used previously to image lipids, proteins, and other metabolites in retinas and lenses. However, the regional composition of phospholipids in vitreous humors is not known. To address this issue, we have applied this mass spectral method to explore the regional phospholipid distribution in porcine vitreous humor both ex-situ and in-vitro. To establish the possible source(s) of phospholipids in the vitreous humor, compositional studies of the lens and retina were also pursued. Due to the overall low levels of phospholipids in vitreous humor, it was necessary to optimize the experimental approaches for ex-situ and in-vitro studies. The sensitivity observed in the spectra of methanol extracts from the lens and retina was higher than that for methanol:chloroform extracts, but the compositional trends were the same. A fourfold improvement in sensitivity was observed in the analysis of vitreous humor extracts obtained with the Bligh and Dyer protocol relative to the other two extraction methods. For ex-situ studies, the 'stamp method' with para-nitroaniline as the matrix was chosen. Throughout the vitreous humor, phosphatidylcholines were the most abundant phospholipids. In-vitro results showed higher relative levels of phospholipids compared to the 'stamp' method. However, more details in the regional phospholipid distribution were provided by the ex-situ approach. Both in-vitro and ex-situ results indicated higher levels of phospholipids in the posterior vitreous region, followed by the anterior and central regions. The posterior region contained more unsaturated species whereas more saturated phospholipids were detected in the anterior region. The observed trends suggest that the phospholipids detected in the posterior vitreous humor migrate from the retina and associated vasculature while those present in

    Radiography is in material examination one of the important research methods. So in the steel and plant construction a variety of studies are carried out. In construction, the dominance is the investigations with radar, ultrasonic echo and so in this contribution especially applications with radiographic methods are discribed. Furthermore the combination with different NDT methods should be presented. In all examples there was a combination of radiography and other non-destructive testing methods. In the first example, there is a combination of radiography with ultrasound echo and drilling resistance to an old oak beam from the St. Mary´s church in Lutherstadt Wittenberg (Germany). Measurements by reinforcement locating and radiography of steel plates in the vault of castle Lustheim near Munich and studies using radar and radiography at a temple in the Pergamon Museum in Berlin round off the examples.

    Background It seems that the core neural regions and cognitive processes implicated in obsessive-compulsive disorder (OCD) pathophysiology may overlap with those involved in humor appreciation. However, to date, there have been no studies that have explored humor appreciation in OCD. The purpose of the present work was to investigate humor appreciation in a group of patients with OCD. Methods We examined 25 patients with OCD and 25 healthy controls, matched by age, education, and gender. We administered Penn's Humor Appreciation Test (PHAT), a computerized test comprising captionless cartoons by Mordillo. Each set of stimuli consisted of two almost identical drawings, one of which was funny due to the alteration of a detail in the cartoon, whereas the other was not funny. Severity of psychopathology was evaluated with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). Results No significant effect for group, gender or group × gender interaction was found on the PHAT scores. In OCD patients, humor appreciation was not significantly associated with age of onset, duration of illness, and obsessions, but correlated significantly with compulsions. Conclusions Humor appreciation, based on captionless cartoons in OCD, does not seem to be deficient compared to healthy subjects but may be related to illness characteristics. PMID:22103926

    Human emotions, such as anxiety, depression, fear, joy, and laughter, profoundly affect psychological and physiological processes. These emotions form a set of basic, evolved functions that are shared by all humans. Laughter is part of a universal language of basic emotions that all humans recognize. Health care providers and educators may utilize the power of laughter to improve health and enhance teaching and learning. This is an important consideration because teaching is not just about content: it is also about forming relationships and strengthening human connections. In this context, when used effectively, humor is documented to build relationships and enhance performance. Specifically, humor improves student performance by attracting and sustaining attention, reducing anxiety, enhancing participation, and increasing motivation. Moreover, humor stimulates multiple physiological systems that decrease levels of stress hormones, such as cortisol and epinephrine, and increase the activation of the mesolimbic dopaminergic reward system. To achieve these benefits, it is important to use humor that is relevant to the course content and not disparaging toward others. Self-effacing humor illustrates to students that the teacher is comfortable making mistakes and sharing these experiences with the classroom. In this brief review, we discuss the history and relationship between humor, laughing, learning, and health with an emphasis on the powerful, universal language of laughter.

    This study assessed the concurrent and prospective associations between psychosocial adjustment and four humor styles, two of which are adaptive (affiliative, self-enhancing) and two maladaptive (aggressive, self-defeating). Participants were 1,234 adolescents (52% female) aged 11-13 years, drawn from six secondary schools in England. Self-reports of psychosocial adjustment (loneliness, depressive symptomatology, and self-esteem) and humor styles were collected at two time points (fall and summer). In cross-lagged panel analyses, self-defeating humor was associated with an increase in both depressive symptoms and loneliness, and with a decrease in self-esteem. In addition, depressive symptoms predicted an increase in the use of self-defeating humor over time, indicating that these may represent a problematic spiral of thoughts and behaviors. Self-esteem was associated with an increase in the use of affiliative humor over the school year but not vice-versa. These results inform our understanding of the ways in which humor is associated with psychosocial adjustment in adolescence.

    This research summarizes the knowledge generated in social psychology and positive psychology about the relationship between humor styles, personality and wellbeing. Specifically, a meta-analysis was performed with the results of 15 studies on humor styles measured by the Humor Styles Questionnaire (Martin, Puhlik-Doris, Larsen, Gray & Weir, 2003) in correlation with the personality traits measured by the Big Five Personality model (measured with different scales). Following the steps presented by Rosenthal (1991) for meta-analysis in the case of correlational research, we calculated the total mean r as an indicator of effect size. Results show that affiliative humor has a strong and homogeneous relation to neuroticism and extraversion. The homogeneity and heterogeneity found between variables and possible explanations are discussed in the conclusion. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    The authors propose an effective technique to isolate whole, intact vitreous core and cortex from post mortem enucleated porcine eyes. While previous studies have shown the results of such dissections, the detailed steps have not been described, precluding researchers outside the field from replicating their methods. Other studies harvest vitreous either through aspiration, which does not maintain the vitreous structure anatomy, or through partial dissection, which only isolates the vitreous core. The proposed method isolates the whole vitreous body, with the vitreous core and cortex intact, while maintaining vitreous anatomy and structural integrity. In this method, a full thickness scleral flap in an enucleated porcine eye is first created and through this, the choroid tissue can be separated from the sclera. The scleral flap is then expanded and the choroid is completely separated from the sclera. Finally the choroid-retina tissue is peeled off the vitreous to leave an isolated intact vitreous body. The proposed vitreous dissection technique can be used to study physical properties of the vitreous humor. In particular, this method has significance for experimental studies involving drug delivery, vitreo-retinal oxygen transport, and intraocular convection.

  3. Eosinophils: important players in humoral immunity.

    Eosinophils perform numerous tasks. They are involved in inflammatory reactions associated with innate immune defence against parasitic infections and are also involved in pathological processes in response to allergens. Recently, however, it has become clear that eosinophils also play crucial non-inflammatory roles in the generation and maintenance of adaptive immune responses. Eosinophils, being a major source of the plasma cell survival factor APRIL (activation and proliferation-induced ligand), are essential not only for the long-term survival of plasma cells in the bone marrow, but also for the maintenance of these cells in the lamina propria which underlies the gut epithelium. At steady state under non-inflammatory conditions eosinophils are resident cells of the gastrointestinal tract, although only few are present in the major organized lymphoid tissue of the gut - the Peyer's patches (PP). Surprisingly, however, lack of eosinophils abolishes efficient class-switching of B cells to immunoglobulin (Ig)A in the germinal centres of PP. Thus, eosinophils are required to generate and to maintain mucosal IgA plasma cells, and as a consequence their absence leads to a marked reduction of IgA both in serum and in the gut-associated lymphoid tissues (GALT). Eosinophils thus have an essential part in long-term humoral immune protection, as they are crucial for the longevity of antibody-producing plasma cells in the bone marrow and, in addition, for gut immune homeostasis. © 2015 British Society for Immunology.

    It has been established by MRI visualization experiments that the convection of nanoparticles and large molecules with high rate of water flow in the vitreous humor will experience resistance, depending on the respective permeabilities of the injected solute. A set of experiments conducted with Gd-DTPA (Magnevist, Bayer AG, Leverkusen, Germany) and 30 nm gadolinium-based particles (Gado CELLTrackTM, Biopal, Worcester, MA) as MRI contrast agents showed that the degree of convective transport in this Darcy-type porous medium varies between the two solutes. These experiments consisted of injecting a mixture of the two (a 30 μl solution of 2% Magnevist and 1% nanoparticles) at the middle of the vitreous of an ex vivo whole bovine eye and subjecting the vitreous to water flow rate of 100 μl/min. The water (0.9% saline solution) was injected at the top of the eye, and was allowed to drain through small slits cut at the bottom of the eyeball. After 50 minutes of pumping, MRI images showed that the water flow carried the Gd-DTPA farther than the nanoparticles, even though the two solutes, being mixed, were subjected to the same convective flow conditions. We find that the convected solute lags the water flow, depending on the solute permeability. The usual convection term needs to be adjusted to allow for the filtration effect on the larger particles in the form (1- σ) u . ∇ c with important implications for the modeling of such systems.

    The Humor Styles Questionnaire (HSQ; Martin et al., 2003) is one of the most frequently used questionnaires in humor research and has been adapted to several languages. The HSQ measures four humor styles (affiliative, self-enhancing, aggressive, and self-defeating), which should be adaptive or potentially maladaptive to psychosocial well-being. The present study analyzes the internal consistency, factorial validity, and factorial invariance of the HSQ on the basis of several German-speaking samples combined (total N = 1,101). Separate analyses were conducted for gender (male/female), age groups (16-24, 25-35, >36 years old), and countries (Germany/Switzerland). Internal consistencies were good for the overall sample and the demographic subgroups (.80-.89), with lower values obtained for the aggressive scale (.66-.73). Principal components and confirmatory factor analyses mostly supported the four-factor structure of the HSQ. Weak factorial invariance was found across gender and age groups, while strong factorial invariance was supported across countries. Two subsamples also provided self-ratings on ten styles of humorous conduct (n = 344) and of eight comic styles (n = 285). The four HSQ scales showed small to large correlations to the styles of humorous conduct (-.54 to .65) and small to medium correlations to the comic styles (-.27 to .42). The HSQ shared on average 27.5-35.0% of the variance with the styles of humorous conduct and 13.0-15.0% of the variance with the comic styles. Thus-despite similar labels-these styles of humorous conduct and comic styles differed from the HSQ humor styles.

    By gasification with oxygen, municipal waste can be converted into a pure, burnable gas. The gas can be used like natural gas, e.g. in boilers and industrial furnaces, gas engines and gas turbines for heat and electric power generation, but also in chemical synthesis processes, e.g. methanol synthesis.

    It was the aim of the project to improve the solar drying process with assistance of solar regenerated sorbents. Fruits, vegetables, herbs and mushrooms were dried in hurdles and calcium chloride solutions were concentrated in black plastic basins with solar energy during the day. At night or at bad meteorological conditions the hurdles with the drying goods were set into the basins and capped in order to continue the drying process. By this means a microbial decay was prohibited and the drying time was shortened roughly by half. (orig.) [Deutsch] Ziel des Vorhabens war es, den Prozess der solaren Trocknung mit Hilfe von solar regenerierten Sorptionsmitteln zu verbessern. Tagsueber wurden mit Solarenergie Fruechte, Gemuese, Kraeuter und Pilze in Horden getrocknet, und Calciumchloridloesungen wurden in schwarzen Kunststoffwannen regeneriert. Zur Fortsetzung der Trocknung waehrend der Nacht und bei unguenstigen Witterungsverhaeltnissen wurden die Horden mit den Trocknungsguetern in die Wannen gesetzt und abgedeckt. Durch dieses Verfahren konnte ein mikrobieller Verderb vermieden und die Trocknungszeit auf ca. die Haelfte verkuerzt werden. (orig.)

    Humor is a potential communication strategy to accomplish various and potentially conflicting consultation goals. We investigated humor use and its reception in diabetes consultations by analyzing how and why humor emerges and its impact on the interaction. We did this by using an interactional sociolinguistics approach. We recorded 50 consultations in an Irish diabetes setting. Analysis of the humor events drew on framework analysis and on concepts from Conversation Analysis and pragmatics. The study also comprised interviews using tape-assisted recall. We identified 10 humor functions and two umbrella functions. A key finding is that most humor is relationship-protecting humor initiated by patients, that is, they voice serious messages and deal with emotional issues through humor. Our findings imply that patients' and providers' awareness of indirect communication strategies needs to be increased. We also recommend that researchers employ varied methods to adequately capture the interactive nature of humor.

MÉTODO: Os artigos foram selecionados por meio de busca eletrônica no indexador PubMed. Capítulos de livros e as listas de referências dos artigos selecionados também foram revisados. RESULTADOS: Observam-se elevados índices de comorbidade entre abuso/dependência de cannabis e transtornos afetivos em estudos transversais e em amostras clínicas. Estudos longitudinais indicam que, em longo prazo, o uso mais intenso de cannabis está relacionado com um risco maior de desenvolvimento de doença bipolar e, talvez, depressão maior em indivíduos inicialmente sem quadros afetivos; porém, os mesmos não encontraram maior risco de uso de cannabis entre aqueles com mania ou depressão sem esta comorbidade. Outra importante observação é que o uso de substâncias psicoativas em bipolares pode estar associado a uma série de características negativas, como dificuldade na recuperação dos sintomas afetivos, maior número de internações, piora na adesão ao tratamento, risco aumentado de suicídio, agressividade e a uma pobre resposta ao lítio. Tratamentos psicossociais e farmacológicos são indicados para o manejo da comorbidade entre cannabis e transtornos afetivos. CONCLUSÃO: As relações entre o uso de cannabis e alterações do humor são observadas tanto epidemiologicamente quanto nos contextos clínicos.OBJECTIVE: Evaluate the relationship between acute and chronic use of cannabis and mood changes.

    The prevalence of antibodies to pancreatic islets in monogenic diabetes remains unknown and the incidence estimation is difficult as the occurrence of autoantibodies in patient is one of the well-known exclusion criteria for further genetic diagnostics. They has been found not only among patients with type 1 diabetes, but also in other types of diabetes: Type 2 diabetes, Latent Autoimmune Diabetes in Adults (LADA) (16) and monogenic diabetes (MD). Immunological characteristic of GCK MODY patients. The study group included families of 27 adolescent patients with GCK MODY (39 parents and 19 siblings) monitored in the Department of Pediatrics, Endocrinology and Diabetes and in the Diabetes Clinic of John Paul II Upper Silesian Child Health Centre in Katowice in the years 2007-2012. All patients and family members with GCK MODY underwent a blood sample drawing for immunological (classic humoral response markers: ICA, GAD, IA-2, IAA) and biochemical diagnostics. Pediatric, diabetes and family medical history was collected from the subjects and parents. Immunological diagnostics was performed in all patients except 1 (96.3%). Immunological diagnostics included 17 (89.5%) parents and 7 (87.5%) siblings with diagnosed GCK MODY. 8 (30.8%) adolescent patients with GCK MODY, 3 subjects (17.64%) among parents (with GCK MODY), as well as 2 subjects (28.57%) among siblings (with GCK MODY) showed a positive antibodies screen. The results of our study in children with GCK MODY and their family members suggest that the occurrence of classic antibodies directed against pancreatic islets antigens is fairly common in patients with GCK MODY. Despite various observations and many legitimate discussions, it is difficult to clarify the pathogenesis of the occurrence of autoantibodies in monogenic diabetes. © Polish Society for Pediatric Endocrinology and Diabetology.

    Waste incineration plants are based on the process of thermal waste treatment, i.e. the generation of power from the controlled conversion of organic reactive residue waste. Statutory requirements forced operators to install powerful flue gas cleaning systems into their existing waste incineration plants. This led to a tremendous increase in cost and treatment prices generating pressure to optimize the process. Currently, markets demand additional capacities for the treatment of waste of elevated heating value ({proportional_to}5,0 MWh/Mg). It is possible to treat this type of waste in a conventional waste incineration plant. However, the elevated heating value dictates a reduction in throughput with ever increasing pressure on costs. This is why current concepts consider the treatment of waste of elevated heating value in specific, so called de-centralized plants. These plants are usually of low throughput with accordingly high specific cost of developing the infrastructure. The capacity of existing waste incineration plants has been investigated in order to assess the potential for optimization. Extensive test runs at the Municipal Solid Waste Incineration Plant (MSW) Darmstadt revealed a capacity gap in the flue gas cleaning system even with the incineration unit running at full capacity. This gap could be filled with an additional incineration plant for waste of elevated heating value, whose capacity is matched accordingly. Such additional incineration plant defines in conjunction with the existing waste incineration plant a so called HYBRID Waste Treatment Plant. It is the aim of this treatise to develop an instrument to support the decision making process related to the planning of such plants. (orig.)

    Dental computer assisted tomography (Dental CT) represents a valuable addition to the diagnostic spectrum for planning oral and maxillofacial surgery. High resolution CT and specially designed computer software allow representation of the jaws in different planes that are easy to match. They further allow the display of very small structures relevant to oral surgical interventions and reveal their spatial relationship in three dimensions. Thus, communication between dentists and radiologists may be intensified and supported by usage of modern telecommunication systems. Dental CT is indicated, when clinical and conventional radiological techniques will not allow exact interpretation of the situation. It is modern oral implantology that primarily benefits from computer software enabling the assessment of surgical sites in the presurgical phase. Such planning was not yet possible using two dimensional radiographic techniques. The dental-implantological part expects from radiography sharply defined contours of the external bony contours and the mandibular canal, exactly defined relation between slices and planes, no distortion in the orthoradial planes, tools for reliable measurements of distances, angles and volumes, possibility to transmit pictures electronically or on hardcopy without loss of quality.

    We intravenously administered flomoxef sodium (FMOX) 120 minutes before cataract surgery, topically administered levofloxacin (LVFX) into the eyes four times at 30-minute intervals before surgery, and measured the aqueous humor concentrations of these agents to investigate their penetration into the aqueous humor and their efficacy in the prevention of postoperative endophthalmitis. Sixty-eight patients who underwent cataract surgery at the Department of Ophthalmology, Yokohama City University School of Medicine, or its affiliate, Kanazawa Hospital, Yokohama, were enrolled in this study. They received one or both of the following: 1.0 g FMOX via a 20-minute intravenous drip and LVFX ophthalmic solution applied four times at 30-minute intervals, both beginning two hours before the operation. Aqueous humor was aspirated from the anterior chamber and assayed for FMOX and LVFX concentrations using high-performance liquid chromatography (HPLC). The mean intraoperative FMOX and LVFX concentrations in the patients' aqueous humor were 1.21 +/- 0.63 microg/ml and 0.69 +/- 0.47 microg/ml, respectively. These concentrations sufficiently exceeded the MIC90 values against Staphylococcus epidermidis, S. aureus, and Propionibacterium acnes. The FMOX and LVFX concentrations in the aqueous humor sampling were adequate to kill bacteria in vitro. These drugs may have efficacy in the prevention of postoperative endophthalmitis in patients undergoing cataract surgery.

The mean intraoperative FMOX concentrations in the patients' aqueous humor were 0.79 +/- 0.24 microg/ml (administered 3.5 hours before surgery)--1.47 0.79 microg/ml (administered 1.5 hours before surgery). These concentrations administered 0.5-3.0 hours before surgery sufficiently exceeded the minimum inhibitory concentration (MIC) 90 values against Staphylococcus epidermidis, Staphylococcus aureus and Propionibacterium acnes, but did not achieve the MIC90 values against Enterococcus faecalis and Pseudomonas aeruginosa. The FMOX concentrations in the aqueous humor sampling were adequate to kill bacteria in vitro. This drug may be efficacious in the prevention of postoperative endophthalmitis in patients undergoing cataract surgery.

    The association between relational aggression and popularity during early adolescence is well established. Yet, little is known about why, exactly, relationally aggressive young adolescents are able to achieve and maintain high popular status among peers. The present study investigated the mediating role of humor in the association between relational aggression and popularity during early adolescence. Also considered was whether the association between relational aggression and humor varies according to adolescents’ gender and their friends’ levels of relational aggression. Participants were 265 sixth-grade students (48% female; 41% racial/ethnic minority; Mage = 12.04 years) who completed peer nomination and friendship measures in their classrooms at two time points (Wave 1: February; Wave 2: May). The results indicated that Wave 1 relational aggression was related to Wave 1 and 2 popularity indirectly through Wave 1 humor, after accounting for the effects of Wave 1 physical aggression, ethnicity, and gender. Additional analyses showed that relational aggression and humor were related significantly only for boys and for young adolescents with highly relationally aggressive friends. The results support the need for further research on humor and aggression during early adolescence and other mechanisms by which relationally aggressive youth achieve high popular status.

    2017-07-01

    Conversation analysis is employed to examine transcribed excerpts drawn from a subsample of 75 naturally occurring and video recorded interviews between cancer patients and 30 doctors. Close examination is provided of how cancer patients initiate, and doctors respond, to laughter and humor during oncology interviews. Interactions demonstrate that communication about the disease "cancer" shares qualities similar to other medical areas (e.g., primary care): the tendency for patients to initiate laughter or humor to address troubling and challenging circumstances; and that during moments when patients address personal matters, doctors are not invited and do not reciprocate with shared laughter and humor. Prominent in talk about cancer are various precarious circumstances, awkward and delicate moments mirroring the lived experiences of cancer patients (e.g., when patients attempt to minimize fears, justify that they are well when threatened with sickness, claim normality in the midst of chronic conditions, and take stances that weight loss and gain are not problematic). These examples provide a compelling case that routine cancer care involves many poignant situations managed through laughter and humor. Implications are raised for how quality care might be improved through grounded understandings of laughter, humor, and cancer.

    Full Text Available Bernadette McCosker, Carmen C MoranSchool of Psychology, Charles Sturt University, Wagga Wagga, NSW, AustraliaBackground: In contrast with an early implicit “facilitative hypothesis” of humor, a revised specificity hypothesis predicts that the benefits of humor depend on the specific style of humor used. Information on predictors of these humor styles in turn enhances the ability to predict the effect on well-being.Methods: We examined the relationships between interpersonal competence, self-esteem, and different styles of humor, while also examining the contributions of age and gender. Participants (n = 201 aged 18–63 years completed the Rosenberg Self-Esteem Inventory, the Interpersonal Competence Questionnaire, and the Humor Styles Questionnaire, and gave demographic information.Results: High self-esteem was associated with higher use of affiliative, aggressive, and self-enhancing humor styles, but lower use of self-defeating humor. High interpersonal competence predicted greater use of affiliative humor, whereas low interpersonal competence predicted greater use of aggressive humor. Further analyses showed that initiation competence predicted affiliative humor (positively but both initiation competence (positively and conflict management competence (negatively predicted aggressive humor.Conclusion: The findings that both self-esteem and initiation competence contribute to use of aggressive humor add to knowledge of who is likely to use this potentially harmful humor style. We conclude that a readiness to initiate humorous interactions is not on its own a general and positive attribute contributing to “good” humor.Keywords: self-esteem, interpersonal competence, humor styles, differential effects

  1. Reconsidering language teaching through a focus on humor

    Full Text Available Formal language education is often predicated on a series of modernist fictions that greatly simplify the nature of language and the process of communication. Acts of linguistic creativity involving humor and language play are frequently either ignored or considered deviant. In this paper, we contribute to ongoing efforts to re-conceptualize language education in ways that make use of more robust (and less modernist theories of language and communication. We revisit calls for more pedagogical focus on humor and language play and illustrate how more attention to these types of language might help us to move away from some of the classroom fictions that currently constrain teachers and learners alike. Specifically, we present recent conceptions of language and of communication, and discuss how, in light of these, humor and language play can be used to increase learners’ metalinguistic awareness and expand their communicative/interpretive repertoires.

  2. Using humor in systematic desensitization to reduce fear.

    Ventis, W L; Higbee, G; Murdock, S A

    2001-04-01

    Effectiveness of systematic desensitization for fear reduction, using humorous hierarchy scenes without relaxation, was tested. Participants were 40 students highly fearful of spiders. Using a 24-item behavioral approach test with an American tarantula, participants were matched on fear level and randomly assigned to 1 of 3 treatment groups: (a) systematic desensitization, (b) humor desensitization, and (c) untreated controls. Each participant was seen for 6 sessions, including pretest and posttest. Analyses of covariance of posttest scores revealed that the 2 treatment groups showed greater reduction in fear than the controls on 3 measures but did not differ from each other. Therefore, humor in systematic desensitization reduced fear as effectively as more traditional desensitization. This finding may have therapeutic applications; however, it may also be applicable in advertising to desensitize fear of a dangerous product, such as cigarettes.

  3. Does Sense of the Humor Make Sense in the Classroom?

    Directory of Open Access Journals (Sweden)

    Freddy Antonio González-Ynfante

    2011-11-01

    Full Text Available This paper studies the importance of humor as a teaching strategy in the classroom, considering the usual lack of motivation and boredom. To analyze whether the “happy teaching and happy learning” may increase effectiveness in the teaching-learning process, the author will discuss how, despite the many benefits it may bring, humor is not used in the classroom due to prejudices and fears. The idea is not for teachers to play the role of a comedian or a clown, but to intervene and get closer to the group with a teaching, didactic purpose through humor. Plato (1992 thought about this; he used to say that sometimes a joke may help, where seriousness put up resistance.

  4. The Use of Humor in Serious Mental Illness: A Review

    2011-01-01

    Full Text Available There is now a relatively good understanding of the broad range of direct and indirect effects of humor and laughter on perceptions, attitudes, judgments and emotions, which can potentially benefit the physical and psychological state. This article presents a review and discussion of the use of humor and laughter in treating people with serious mental illness, distinguishing between clinical papers on individual and group psychotherapy, and empirical research reports describing humor and laughter interventions. In spite of the exponential growth of the field over the last 30 years, I conclude that empirical studies are still lacking, the studies that do exist have major methodological shortcomings, and the field is in dire need of further investigation.

    Full Text Available This paper investigates the concepts of humor and violence and their complex relationships contextualised in the advertising domain. Thus, the main theories of humor and the most important elements from media violence paradigms are critically pointed out. The effects of comedic violence in advertising may be positive (great involvement with the ad message, retention of brand information, higher pass-along probability, and also negative (offending the audience, desensitization, damaging the reputation and the brand equity. A lot of factors change the perception of comedic violent ads (gender, social norm beliefs etc., so that a multidimensional analysis of consumer perceptions is needed if we want to draw a more accurate picture of this phenomenon. The analysis of the specific ad that I developed in the second part of this paper showed clearly the interplay between perceived humor and perceived violence and also the relevance of the cultural background in its interpretation.

  6. Development of an analysis method for determining chlorinated hydrocarbons in marine sediments and suspended matter giving particular consideration to supercritical fluid extraction; Entwicklung eines Analysenverfahrens zur Bestimmung von chlorierten Kohlenwasserstoffen in marinen Sedimenten und Schwebstoffen unter besonderer Beruecksichtigung der ueberkritischen Fluidextraktion

    1997-11-01

    The purpose of the present study was to develop an analysis method for chlorinate hydrocarbons in marine environments using supercritical fluid extraction (SFE) instead of conventional approaches. In order to apply this extraction method the available SFE device had to be extended and all the individual steps of the analysis method had to be optimised and adapted. As chlorinated hydrocarbons only occur at very low concentrations in marine environments (ppm to ppt range) the analysis method had to be extremely sensitive. High sensitivity, in town, is generally associated with a high susceptibility of an analysis method to faults through contamination or losses. This meant that the entire method and all its individual steps had to scrutinised for such weak points and improved where necessary. A method for sampling suspended matter in marine environments had to be developed which permits efficient separation of the smallest possible particles from seawater. The designated purpose of the developed analysis method is to deal with topical aspects of marine chemistry relating to sources, transport, distribution, and the fate of chlorinated hydrocarbons in marine environments. (orig.) [Deutsch] Ziel der vorliegenden Arbeit ist, ein Analysenverfahren fuer chlorierte Kohlenwasserstoffe in der marinen Umwelt zu entwickeln. Dabei soll die ueberkritische Fluidextraktion (SFE) anstelle herkoemmlicher Verfahren eingesetzt werden. Fuer die Anwendung dieser Extraktionsmethode ist es erforderlich, das zur Verfuegung stehende SFE-Geraet zu erweitern und saemtliche Teilschritte des Analysenverfahrens zu optimieren und auf diese Methode abzustimmen. Der Umstand, dass die chlorierten Kohlenwasserstoffe nur in sehr geringen Konzentrationen in der marinen Umwelt vorkommen (ppm- bis ppt-Bereich), erfordert eine sehr hohe Empfindlichkeit des Analysenverfahrens. Eine hohe Empfindlichkeit bedingt eine grosse Stoeranfaelligkeit des Analysenverfahrens durch Kontaminationen oder Verluste. Aus

    2016-03-01

    Humor is, from a psychological point of view, a complex process involving cognitive, affective, interspersonal and social elements in a interpersonal context. Its cognitive core is based on the perception of incongruity between two related inconsistent or contradictory mental representations. The total or partial resolution of incongruity in a playful frame is associated with a specific positive emotion, which characteristics and intensity are determined by the structure of the humoristic stimulus more than its content, and the personal and social contexts. Main theories of humor are reviewed as well as its development, its cognitive and affective correlates, and the influence of genre, age and personality.

    As a mature science, geophysics often employs abstract mathematical ideas in the development of methods to query the physical system. Since abstract mathematics is not usually part of the traditional meteorological education, it is sometimes necessary to communicate these ideas in a manner that not only explains but also demystifies them. Humor is an ideal tool for allowing an audience to develop a degree of comfort with unfamiliar concepts. I will give several examples where abstract ideas are made concrete in the context of stochastic climate modeling by use of humorous presentations.

    Blanc, Nathalie; Brigaud, Emmanuelle

    2014-01-01

    This study tested the effect of humor in one particular type of print advertisement: the preventive health ads for three topics (alcohol, tobacco, obesity). Previous research using commercial ads demonstrated that individuals' attention is spontaneously attracted by humor, leading to a memory advantage for humorous information over nonhumorous information. Two experiments investigated whether the positive effect of humor can occur with preventive health ads. In Experiment 1, participants observed humorous and nonhumorous health ads while their viewing times were recorded. In Experiment 2, to compare humorous and nonhumorous ads, the memory of health messages was assessed through a recognition task and a convincing score was collected. The results confirmed that, compared to nonhumorous health ads, those using humor received prolonged attention, were judged more convincing, and their messages were better recognized. Overall, these findings suggest that humor can be of use in preventive health communication.

    2016-01-01

    Throughout the literature, humor has demonstrated positive effects on memory and learning, as well as physiological and psychological well being. Research has described improvements in communication and trust through the use of humor in the nurse-patient relationship. The utilization of humor with certain populations, including those with anxiety disorders, cancer patients and mood disorders has also been widely described in the literature but little research has been conducted with humor use in patients' recovery from substance use disorders. This population might benefit from the thoughtful applications of humor to promote laughter and mirth as well as learning recovery principles. A review of the humor theories, theoretical processes and humor styles are discussed for their use in individuals with substance use disorders, in particularly for early recovery engagement in 12 step programs and other recover support social networks. The application of humor in efforts to support recovery with substance use disorder patients is worth investigating further.

    Full Text Available The article discusses how humor could enrich social work practice and guideline social workers. Social work field is not that traditionally relates with humor. While social work scholars argue that social work field is full of contradictions and humor is relevant tool to express those contradictions and paradoxes. In micro level practice Gitterman (2003 suggests humor could be a creative tool that “must be used differently based on client background, level of functioning, and specific situation”. Article presents results of qualitative study. The analysis of social workers’ professional experiences is based on social constructionism perspective with the aim to explain how humor is used in everyday practice and how use of purposive humor could be helpful in social work intervention. Episodic interviews with six social workers working in intercultural social work field were conducted. Transcripts of interviews were analyzed through conceptualization, developing story and maximizing aims of the study. Anonymity and confidentiality was considered. The results of analysis demonstrate that humor is unique experience in the sociocultural context. Discursive categories explain the purpose of humor for practice, circumstances and conditions for using that determine how the use of humor could contribute to the success of a social worker-client interaction. Using humor is considered as professional competence, which suggests that “having a good sense of humor” and appropriate use of humor with ability to demonstrate empathy and honesty in social worker-client interaction is an important part of social worker competence. Humor as a professional competence contained understanding of the humorous taboo. During analysis were explored how using humor and cultural stories of clients create mezzo level strategies for professional social work practice. Keywords: humor in social work practice, social work process, humor taboo.

  14. Humorous Names in the Light of Incongruity Theory

    Directory of Open Access Journals (Sweden)

    Mariusz Rutkowski

    2016-07-01

    Full Text Available The article addresses the humorous function of proper names in the light of incongruity theory. It aims at proving that, although names are often defined as pragmatically “transparent,” they may possess some humorous value due to semantic and pragmatic shifts resulting from the disturbance of ordinary patterns of proper names identification and interpretation. After a brief introduction, the author discusses different variants of incongruity theory as resented in the works by Victor Raskin and Thomas C. Veatch as well as their possible application to the study of humorous names. The second part of the paper provides an analysis of the humorous effects of proper names which includes anthroponyms, toponyms, trade names, football team names and names in literature. The first section of this part concentrates on names in which humour is unintentional and seems to be induced by the context, while the second section focuses on names which are intentionally humourous, i.e. supposed to amuse from the moment of their creation. The author argues that the incongruity theory can provide a useful framework for the study of the different mechanisms responsible of the semantic shifts which determine the variation of pragmatic values of proper names.

    Full Text Available We determined the antioxidant status of the aqueous humor after extracapsular lens extraction in 14 mongrel dogs weighing about 10 kg. The animals were examined by slit lamp biomicroscopy, applanation tonometry and indirect ophthalmoscopy. One eye was submitted to conventional extracapsular lens extraction and the other was used as control. Samples of aqueous humor were obtained by anterior chamber paracentesis before and at days 1, 2, 3, 7 and 15 after surgery. Total antioxidant status was determined as the capacity of aqueous humor to inhibit free radical generation by 2,2-azobis(2-amidopropane chlorine. Ascorbic acid concentration was measured by HPLC with UV detection. Protein content was determined with the biuret reagent. Statistical analysis was performed by ANOVA followed by the Tukey-Kramer test. Protein concentration increased from 0.61 to 22 mg/ml 24 h after surgery. These levels were maintained and returned to normal at day 7. Total antioxidant capacity was reduced from 50 to about 30 min until day 3 and at day 7 it was equal to control. Ascorbic acid levels were reduced from 252 to about 110 µM and then returned to control values at day 15. Considering the importance of ascorbic acid concentration in aqueous humor for the maintenance of the antioxidant status of the anterior segment of the eye, the decrease of antioxidant defenses suggests that the surgical procedures promote an oxidative stress condition in the eye.

    Antibiotics such as fluoroquinolones (FQLs) are commonly used to treat ocular infections but are also known to cause dermal melanocyte toxicity. The release of dispersed pigments from the iris into the aqueous humor has been considered a possible ocular side effect of the systemic administration of FQLs such as Moxifloxacin, and this condition is known as bilateral acute iris transillumination (BAIT). Bilateral acute depigmentation of iris (BADI) is a similar condition, with iris pigment released into the aqueous, but it has not been reported as a side effect of FQL. Iris pigments are synthesized by the melanogenic enzyme tyrosinase (TYR) and can be detected but not quantified by using slit-lamp biomicroscopy. The correlation between dispersed pigments in the aqueous and the extent of melanocyte toxicity due to topical antibiotics in vivo is not well studied. Here, we aimed to study the effect of topical FQLs on iris tissue, the pigment release in the aqueous humor and the development of clinically evident iris atrophic changes. We evaluated this process by measuring the activity of TYR in the aqueous humor of 82 healthy eyes undergoing cataract surgery following topical application of FQLs such as Moxifloxacin (27 eyes, preservative-free) or Ciprofloxacin (29 eyes, with preservative) or the application of non-FQL Tobramycin (26 eyes, with preservative) as a control. In addition, the patients were questioned and examined for ocular side effects in pre- and post-operative periods. Our data showed a significantly higher mean TYR activity in the aqueous humor of Ciprofloxacin-treated eyes compared to Moxifloxacin- (preservative free, p iris melanocytes. However, the reduced TYR activity in the aqueous of Moxifloxacin-treated eyes was possibly due to the presence of a higher drug concentration, which inhibits TYR activity. Consistently, immunoblotting analysis of the aqueous humor from both Ciprofloxacin- and Moxifloxacin-treated eyes showed the presence of soluble

    Hereditary hyperferritinemia cataract syndrome (HHCS) is a rare autosomal dominant hereditary disease, characterized by hyperferritinemia but with absence of body iron excess and early onset of bilateral cataracts. Although 5- to 20-fold increased serum ferritin concentrations have been reported in HHCS patients, data of ferritin levels in aqueous humor have not been obtained. We therefore aimed to investigate the ferritin levels in aqueous humor and serum and further present histological and ultrastructural data of the lens. During cataract extraction and intraocular lens implantation, aqueous humor and lens aspirate of a 37-year-old HHCS patient were obtained from both eyes. Ferritin levels in serum and aqueous humor were quantitatively analyzed via immunoassays in the HHCS patient and healthy control subjects (n = 6). Lens aspirate in HHCS was analyzed histologically and at the ultrastructural level. Further, genetic mutation screening by polymerase chain reaction and DNA sequencing in blood was performed. Serum ferritin levels in the control group were 142.2 ± 38.7 μg/L, whereas in the HHCS patient, this parameter was excessively increased (1086 μg/L). Analysis of ferritin in aqueous humor revealed 6.4 ± 3.8 μg/L in normal control subjects and 146.3 μg/L (OD) and 160.4 μg/L (OS) in the HHCS patient. DNA analysis detected a C>A mutation on position +18, a T>G mutation on position +22, a T>C mutation on position +24, and a T>G polymorphism on position +26 in the iron-responsive element of the light-chain ferritin (L-ferritin) gene. In the HHCS patient, a 23-fold (OD) to 25-fold (OS) increased aqueous humor ferritin level was detected. Therefore, the formation of bilateral cataract in HHCS is most likely a result of elevated aqueous humor ferritin. In addition, a novel mutation in this rare disease in the iron-responsive element of L-ferritin gene is reported.

    The aim of this programme was the determination and optimization of mechanical testing procedures in order to enable a service life prediction for turbine blades as well as to measure the life consumption of blades which have already been in service. Under these testing conditions procedures were to be investigated which lead to a prolongation of the service life of the blades. The results have shown that the rig test at constant values of load and temperature, which are typical for service conditions, is sufficient for the laboratory simulation. The life consumption of blades run in the engine can be determined by measuring the residual creep life in the rig test. Using the resulting data the life consumption of a particular blade run in the engine can be estimated by the non-destructive measurement of its elongation. The precision of residual life prediction is raised by respecting the master heat and porosity of the blades. From the investigation of high-temperature corrosion resistant coatings it follows that IN 100 can be protected against the attack of sea salt over its whole creep life by coating with a precious metal modified aluminide or by LPPS- or EB-PVD-MCrAlY-coatings. By aluminising, the cooling channels of turbine blades can be protected against oxidation over more than 700 h in the temperature/load cycling test. However, the coating technique used is only applicable under laboratory conditions. In contrary, internal coating by pulse aluminising, which is compatible to production conditions, showed less oxidation resistance.

    Full Text Available Theories about black humor usually regard that it as a contemporary phenomenon and a culmination of the literary modernism and beginning of post-modernism. My intent in this paper is to refute the thesis that the black humor is a modern invention. I am going to prove its existence still in Greek antiquity, quoting and analyzing humorous epitaphs and black humor epigrams. Putting in relation black humor with the joy and humor in religious (fertility and funeral rituals, I am also going to set a question about the attitude to death and life inherent for this kind of humor, arguing that its origin should be searched in the folk tradition.

  9. Rumination, Suicidal Ideation, and the Mediating Effect of Self-Defeating Humor

    2014-08-01

    Full Text Available Research has demonstrated that a self-defeating humor style is related to indicators of psychopathology and interpersonal dysfunction, including depression, anxiety, loneliness, thwarted belongingness, and perceived burdensomeness. The current study continued this investigation by examining how self-defeating humor is related to suicidal ideation and a ruminative response style. Analyses indicated that a self-defeating humor style was positively associated to rumination, brooding, reflection, and suicidal ideation. Results of bootstrapping analyses indicated that self-defeating humor mediated the relationship between rumination and suicidal ideation. This same effect was seen for both brooding and reflection individually. Results indicate that self-defeating humor may serve as an interpersonal means of ruminating as this humor style involves consistent focus on perceived flaws and weaknesses. The assessment of this humor style may provide additional information about the maintenance of suicidal thinking.

    In this study we aimed to examine the contents of humor in the Japanese workplace and to understand the effects of humor on mental/physical health and self-evaluation of job performance. Japanese workers (N = 436) responded to questionnaires addressing workplace humor, feelings about workplace, workplace communication, mental/physical health, and perceived job performance. An exploratory factor analysis indicated that there are five types of workplace humor: norm-violating humor, experience-sharing humor workplace-enjoying humor, people-recalling humor, and outside-mocking humor. A covariance structural analysis showed that norm-violating humor and workplace-enjoying humor decreased mental and physical health by promoting both negative feelings in the workplace and self-disclosure about the negative side of work. Results also revealed that experience-sharing humor, people-recalling humor, and outside-mocking humor had a positive effect on the self-evaluation of job performance as well as mental and physical health, by promoting both positive feelings and mutual communication in the workplace. Results suggest that humor in the workplace has various influences on workers depending on the type of workplace humor.

    2014-08-01

    Full Text Available In this interview, Dr. Arnie Cann discusses his research and views on the ubiquitous role of humor in psychological health and well-being. The interview begins with Professor Cann recounting how he originally became interested in studying humor. He then reflects on the main findings associated with the wide variety of humor-related studies he has conducted over the years. In doing so, Dr. Cann provides suggestions and ideas for further research investigating the role of humor in health and well-being. Specific topic areas discussed include the use of humor in the workplace and other social domains, personality approaches to humor, humor and interpersonal processes, humor and psychopathology, and humor’s role in dealing with stress and well-being. One of the prominent themes in this interview is the clear recognition of sense of humor as a multi-dimensional construct that includes various components that may either be beneficial or detrimental to well-being. A further important theme is the major distinction between humor as an inherent personality construct versus humor that results from exposure to stimuli (e.g., a comedy film. Comments are also provided by Dr. Cann on how the positive affect stemming from humor may be of particular benefit to the individual. Also discussed is the recent move to more fully integrate contemporary humor research with positive psychology approaches. The interview concludes with Dr. Cann providing several recommendations regarding future theorizing and research on the role of humor in psychological well-being.

    Humans naturally have a sense of humor. Experiencing humor not only encourages social interactions, but also produces positive physiological effects on the human body, such as lowering blood pressure. Recent neuro-imaging studies have shown evidence for distinct mental state changes at work in people experiencing humor. However, the temporal characteristics of these changes remain elusive. In this paper, we objectively measured humor-related mental states from single-trial functional magnetic resonance imaging (fMRI) data obtained while subjects viewed comedy TV programs. Measured fMRI data were labeled on the basis of the lag before or after the viewer’s perception of humor (humor onset) determined by the viewer-reported humor experiences during the fMRI scans. We trained multiple binary classifiers, or decoders, to distinguish between fMRI data obtained at each lag from ones obtained during a neutral state in which subjects were not experiencing humor. As a result, in the right dorsolateral prefrontal cortex and the right temporal area, the decoders showed significant classification accuracies even at two seconds ahead of the humor onsets. Furthermore, given a time series of fMRI data obtained during movie viewing, we found that the decoders with significant performance were also able to predict the upcoming humor events on a volume-by-volume basis. Taking into account the hemodynamic delay, our results suggest that the upcoming humor events are encoded in specific brain areas up to about five seconds before the awareness of experiencing humor. Our results provide evidence that there exists a mental state lasting for a few seconds before actual humor perception, as if a viewer is expecting the future humorous events. PMID:24324656

    To measure the nitric oxide (NO) levels of aqueous humor in rabbits after photorefractive keratectomy (PRK) and to evaluate the alterations of NO levels according to the PRK surgery steps, ablation depth, and time. Fifty eyes of 25 New Zealand white rabbits were included in the study. One eye was later randomly excluded from the study in order to equalize the number of eyes in groups. Eyes were divided into seven groups, each comprising seven eyes: unwounded control (Group 1), epithelial scrape (Group 2; aqueous humor samples taken at the 4th hour), superficial PRK (Group 3; samples taken at the 4th hour), deep PRK (Group 4; samples taken at the 4th hour), epithelial scrape (Group 5; samples taken at the 24th hour), superficial PRK (Group 6; samples taken at the 24th hour), and deep PRK (Group 7; samples taken at the 24th hour). The corneal epithelium was mechanically removed in surgical groups. The authors performed superficial corneal ablation (59 microm) in Groups 3 and 6 and deep corneal ablation (99 microm) in Groups 4 and 7. Aqueous humor samples were taken at the 4th hour (Groups 2-4) or 24th hour (Groups 5-7) after corneal surgeries. NO measurements were performed indirectly by using the Griess reaction with a spectrophotometer. Aqueous humor NO levels 4 hours after corneal surgery were statistically significantly lower than the control group (p0.05). At the 24th hour, the deep PRK group had significantly lower NO levels than both the control group and Groups 5 and 6 (p0.05) but remained stable at lower levels in deep PRK groups (p<0.05). Corneal surgery caused low NO levels in aqueous humor 4 hours after surgery. However, 24 hours after surgery, NO levels normalized following epithelial scrape and superficial PRK and were stable at lower levels in the deep PRK group. Complications of deep PRK application are possibly induced by low NO existence in the aqueous humor.

    2015-01-01

    Those who work with human trauma often use humor to handle job stressors. Research has demonstrated that lighthearted humor is related to lower secondary traumatic stress scores, while gallows humor has the inverse relationship. This work explores how three types of humor relate to secondary traumatic stress: (a) humor at the expense of victims, (b) humor at the expense of offenders, and (c) humor containing sexual innuendo. Internet crimes against children taskforce personnel completed questionnaires about secondary traumatic stress and coping techniques. Humor at the expense of victims was rarely used, but when it was, it was indicative of higher secondary traumatic stress. There were no relationships between secondary traumatic stress and the use of humor at the expense of offenders or humor containing sexual innuendo.

    Full Text Available Some animated movies use humor to capture the full attention of its audience. In so doing, the movie’s messages have become a great concern for many theorists and critics by virtue of the idea that a movie can be a repository of ideologies meant to construct a certain type of easy-going and noncritical audience. This paper, therefore, takes the example of Max Fleischer’s Popeye the Sailor Meets Ali Baba and his Forty Thieves (1937 and Robert Clampett’s Ali Baba Bound (1941 as its case studies aiming at spotting the different manifestations of humor, taking Arabs as its subject-matter, becoming a leaked ideology and taming the discourse that is amplified, manipulated, and delivered to the Western public in unwarrantable ways compared to the imagery of Westerners.

  19. Mother, melancholia, and humor in Erik H. Erikson's earliest writings.

    Science.gov (United States)

    Capps, Donald

    2008-09-01

    Erik H. Erikson wrote three articles when he was in his late-twenties and an up-and-coming member of the psychoanalytic community in Vienna. At the time he wrote these articles, he was in a training psychoanalysis with Anna Freud, teaching at the Heitzing School in Vienna, and learning the Montessori method of teaching. These articles focus on the loss of primary narcissism and the development of the superego (or punitive conscience) in early childhood, especially through the child's conflict with maternal authority. They support the idea that melancholia, with its internalized rage against the mother, is the inevitable outcome of the loss of primary narcissism. I note, however, that the third of these articles makes a case for the restorative role of humor, especially when Freud's view that humor is a function of the superego is taken into account.

    The immune system is an important regulatory mechanism affected by spaceflights. In a previous work, we performed a first study of the humoral immune response induced by the immunization of Pleurodeles waltl during a 5 months stay onboard the Mir space station. This analysis indicated that heavy-chain variable domains of specific IgM are encoded by genes of the VHII and VHVI families. However, the contributions of these two families to IgM heavy-chains are different in flown animals [1]. To better understand this immune response modification, we have now determined how individual VH genes have been used to build specific IgM binding sites in animals immunized on earth or in space. This new study revealed quantitative and qualitative modifications in VH genes expression. These data confirm that a spaceflight might affect the humoral response.

    Humor is found to be an essential element of creative thinking in Western culture. In Eastern culture, however, the relationship between creativity and humor is ambivalent. This study examined the relationship among humor styles, creative personality traits, and creative thinking abilities. A sample of 118 Chinese undergraduates in Hong Kong was recruited to complete the Humor Styles Questionnaire, the three Creative Personality subscales of the Chinese Personality Assessment Inventory-2 (CPAI-2), and the Verbal Test of the Wallach-Kogan Creativity Tests. Results show that humor styles are uncorrelated with creative thinking abilities of flexibility, fluency, and originality, but affiliative humor and aggressive humor are correlated with creative personality traits of novelty and diversity. A hierarchical multiple regression shows that both humor styles and creative personality traits of novelty and diversity account for non-significant variance on creative thinking abilities. These findings largely support a hypothesized non-association between humor styles and creative measures. They also pose a sharp contrast to findings obtained in the West, in which humor styles are typically correlated with both creative thinking abilities and creative personality traits.

    Full Text Available Past research suggests that sense of humor may play a role in anxiety. The present study builds upon this work by exploring how individual differences in various humor styles, such as affiliative, self-enhancing, and self-defeating humor, may fit within a contemporary research model of anxiety. In this model, intolerance of uncertainty is a fundamental personality characteristic that heightens excessive worry, thus increasing anxiety. We further propose that greater intolerance of uncertainty may also suppress the use of adaptive humor (affiliate and self-enhancing, and foster the increased use of maladaptive self-defeating humor. Initial correlational analyses provide empirical support for these proposals. In addition, we found that excessive worry and affiliative humor both served as significant mediators. In particular, heightened intolerance of uncertainty lead to both excessive worry and a reduction in affiliative humor use, which, in turn, increased anxiety. We also explored potential humor mediating effects for each of the individual worry content domains in this model. These analyses confirmed the importance of affiliative humor as a mediator for worry pertaining to a wide range of content domains (e.g., relationships, lack of confidence, the future and work. These findings were then discussed in terms of a combined model that considers how humor styles may impact the social sharing of positive and negative emotions.

    Little is known about humor and purpose in life in people with dementia. Although having a sense of humor is typically associated with positive psychological outcomes, recent evidence suggests that outcomes may vary depending on whether the humor being used is adaptive versus maladaptive. The goal of this study was to determine whether humor styles are predictive of purpose in life in people with dementia. Questionnaires were verbally administered to people with mild-to-moderate dementia to measure humor styles and purpose in life. Adaptive humor styles were associated with purpose in life whereas maladaptive humor styles were not. Having a sense of humor in dementia may be associated with a stronger sense of purpose in life, but it depends on the type of humor used. Results are discussed in the context of understanding the role of humor in the daily lives of people with dementia and implications for care. © The Author(s) 2018.

    Martin, Rod; Kuiper, Nicholas A

    2016-08-01

    Since the start of the 21st century, the investigation of various psychological aspects of humor and laughter has become an increasingly prominent topic of research. This growth can be attributed, in no small part, to the pioneering and creative work on humor and laughter conducted by Professor Rod Martin. Dr. Martin's research interests in humor and laughter began in the early 1980s and continued throughout his 32 year long career as a professor of clinical psychology at the University of Western Ontario. During this time, Dr. Martin published numerous scholarly articles, chapters, and books on psychological aspects of humor and laughter. Professor Martin has just retired in July 2016, and in the present interview he recounts a number of research highlights of his illustrious career. Dr. Martin's earliest influential work, conducted while he was still in graduate school, stemmed from an individual difference perspective that focused on the beneficial effects of sense of humor on psychological well-being. This research focus remained evident in many of Professor Martin's subsequent investigations, but became increasingly refined as he developed several measures of different components of sense of humor, including both adaptive and maladaptive humor styles. In this interview, Dr. Martin describes the conceptualization, development and use of the Humor Styles Questionnaire, along with suggestions for future research and development. In doing so, he also discusses the three main components of humor (i.e., cognitive, emotional and interpersonal), as well as the distinctions and similarities between humor and laughter. Further highlights of this interview include Professor Martin's comments on such diverse issues as the genetic versus environmental loadings for sense of humor, the multifaceted nature of the construct of humor, and the possible limitations of teaching individuals to use humor in a beneficial manner to cope with stress and enhance their social and

  12. Investigating vision in schizophrenia through responses to humorous stimuli

    Full Text Available The visual environment of humans contains abundant ambiguity and fragmentary information. Therefore, an early step of vision must disambiguate the incessant stream of information. Humorous stimuli produce a situation that is strikingly analogous to this process: Funniness is associated with the incongruity contained in a joke, pun, or cartoon. Like in vision in general, appreciating a visual pun as funny necessitates disambiguation of incongruous information. Therefore, perceived funniness of visual puns was implemented to study visual perception in a sample of 36 schizophrenia patients and 56 healthy control participants. We found that both visual incongruity and Theory of Mind (ToM content of the puns were associated with increased experienced funniness. This was significantly less so in participants with schizophrenia, consistent with the gestalt hypothesis of schizophrenia, which would predict compromised perceptual organization in patients. The association of incongruity with funniness was not mediated by known predictors of humor appreciation, such as affective state, depression, or extraversion. Patients with higher excitement symptoms and, at a trend level, reduced cognitive symptoms, reported lower funniness experiences. An open question remained whether patients showed this deficiency of visual incongruity detection independent of their ToM deficiency. Humorous stimuli may be viewed as a convenient method to study perceptual processes, but also fundamental questions of higher-level cognition.

    Full Text Available The effects of bimatoprost on aqueous humor dynamics were quantified in monkey eyes. Uveoscleral outflow was measured by the anterior chamber perfusion method, using FITC-dextran. Total outflow facility was determined by the two-level constant pressure method. Aqueous flow was measured with a scanning ocular fluorophotometer. Uveoscleral outflow was 0.96±0.19 L min−1 in vehicle-treated eyes and 1.37±0.27 L min−1 (=6; <.05 in eyes that received bimatoprost 0.01% b.i.d. × 5 days. Bimatoprost had no effect on total outflow facility, which was 0.42±0.05 L min−1 at baseline and 0.42±0.04 L min−1 after bimatoprost treatment. Bimatoprost had no significant effect on aqueous humor flow. This study demonstrates that bimatoprost increases uveoscleral outflow but not total outflow facility or aqueous humor flow, indicating that it lowers intraocular pressure in ocular normotensive monkeys by a mechanism that exclusively involves uveoscleral outflow.

  1. The components of the unique Zur regulon of Cupriavidus metallidurans mediate cytoplasmic zinc handling.

    Zinc is an essential trace element and at the same time it is toxic at high concentrations. In the beta-proteobacterium Cupriavidus metallidurans the highly efficient removal of surplus zinc from the periplasm is responsible for its outstanding metal resistance. Rather than having a typical Zur-dependent, high-affinity ATP-binding cassette transporter of the ABC protein superfamily for zinc uptake at low concentrations, C. metallidurans instead has the secondary zinc importer ZupT of the ZRT/IRT (ZIP) family. It is important to understand, therefore, how this zinc-resistant bacterium copes when it is exposed to low zinc concentrations. Members of the Zur regulon in C. metallidurans were identified by comparing the transcriptomes of a Δ zur mutant and its parent strain. The consensus sequence of the Zur-binding box was derived for the zupTp promoter-regulatory region using a truncation assay. The motif was used to predict possible Zur-boxes upstream of Zur regulon members. Binding of Zur to these boxes was confirmed. Two Zur-boxes upstream of the cobW 1 gene, encoding a putative zinc chaperone, proved to be required for complete repression of cobW 1 and its downstream genes in cells cultivated in mineral salts medium. A Zur box upstream of each of zur-cobW 2 , cobW 3 and zupT permitted low-expression level of these genes plus their up-regulation under zinc starvation conditions. This demonstrates a compartmentalization of zinc homeostasis in C. metallidurans with the periplasm being responsible for removal of surplus zinc and cytoplasmic components for management of zinc as an essential co-factor, with both compartments connected by ZupT. Importance Elucidating zinc homeostasis is necessary to understand both host-pathogen interactions and performance of free-living bacteria in their natural environment. Escherichia coli acquires zinc under low zinc concentrations by the Zur-controlled ZnuABC importer of the ABC superfamily, and this was also the paradigm for other

    The foam flotation of coal mined underground gives better yields if one uses a water in oil emulsion of sodium polyacrytate. It is best to use 0.007 to 0.227 kg of dry sodium polyacrylate on a tonne of dry coal. The use of an aliphatic hydrocarbon and a stabiliser for the emulsion is preferred. Several examples are given, which enable one to judge the results.

    Water transport in polymer electrolyte membrane fuel cells (PEMFC) was non-destructively studied during operation with synchrotron X-ray radiography and tomography. The focus was set on the influence of the three-dimensional morphology of the cell materials on the water distribution and transport. Water management is still one of the mayor issues in PEMFC research. If the fuel cell is too dry, the proton conductivity (of the membrane) decreases leading to a performance loss and, in the worst case, to an irreversible damage of the membrane. On the other hand, the presence of water hinders the gas supply and causes a decrease in the cell performance. For this reason, effective water transport is a prerequisite for successful fuel cell operation. In this work the three-dimensional water transport through the gas diffusion layer (GDL) and its correlated with the 3D morphology of the cell materials has been revealed for the first time. It was shown that water is transported preferably through only a few larger pores which form transport paths of low resistance. This effect is pronounced because of the hydrophobic properties of the employed materials. In addition, water transport was found to be bidirectional, i. e. at appropriate locations a back and forth transport between GDL and flow field channels was observed. Furthermore, liquid water in the GDL was found to agglomerate preferably at the ribs of the flow field. This can be explained by condensation due to a temperature gradient in the cell and by the position, which is sheltered from the gas flow. Larger water accumulations in the gas supply channels were mainly attached to the channel wall opposing the GDL. The gas flow can bypass these agglomerations allowing a continuous gas supply. Moreover, it was shown that randomly distributed cracks in the micro porous layers (MPL) play an important role for the agglomeration of liquid water as they form preferred low resistance transport paths. In this work also perforated MPL/GDL-materials were investigated. It had been shown in complementary measurements that depending on process parameters perforated MPL/GDL materials can have either a positive or in other cases a negative impact on the cell performance (gains of up to 20 % vs. losses of same magnitude). The water transport was found to be responsible for the different behavior. At its best, the perforations have a drainage effect which facilitates effective water removal. In other cases a flooding of the whole local pore area around the perforation was observed. This area was obviously heat affected by laser perforation procedure and showed a hydrophilic behavior. The transport through the perforations was also found to be bidirectional. In this work, specially adapted measuring techniques were applied to analyze various aspects of water management. For example the combination of dynamic radiographic and three-dimensional tomographic measurements has been proven as valuable method to interpret transport phenomena in terms of the underlying cell structure. On top of that a method is applied, which allows for an increased spatial resolution in tomography and the easy switch between radiographic and tomographic measure mode. By comparing the tomographic data of the cell measured subsequent to operation with the dry reference state it was possible to extract the three-dimensional quasi in situ water distribution. This allows for more detailed analyses, for example, statistical water cluster size distributions. The extracted water distribution was also used by a group at the ZSW Ulm for the model validation of a grand canonical Monte Carlo simulation.

    General globalisation and increasing orientation of exporting branches of environmental technology towards the so called developing countries or threshold countries require new technological approaches which facilitate sustainable management in those countries especially with waste and sewage treatment. In order to protect ground and surface waters and to reduce ecological damages / nutrient discharge there is an urgent demand to remove not only oxygen consuming organic carbon compounds, but for example also ammonia-nitrogen, nitrate-nitrogen and phosphorus from wastewater in order to prevent further eutrophication of the waters. However it is known that this results in a high technological and financial expenditure. The algae reactor developed in the research project makes use of the synergetic effect of heterotrophic and photoauto-/-heterotrophic organisms immobilized on an inert carrier material as biofilm, in order to achieve a purification efficiency that could so far only be reached with costly procedural solutions. The auto- and heterotrophic microalgae and cyanobacteria established in the biofilm contributed to the COD-decomposition and the oxygen supply for the heterotrophic bacteria in the biofilm. This synergetic effect enabled a COD-decomposition of up to 94%. The developed and tested process allowed for an extensive nitrogen decomposition of up to 80%. The phosphorus reduction correlated with the content of green algae in the biofilm and amounted up to 40%. The excess biomass formed during the process could be anaerobically converted into biogas at high methane contents (up to 74%). Alternatively, the excess biomass could also be utilized as NPK-fertilizer. A first calculation of profitability showed that the compact design and the fact that a technical ventilation of the algae reactor is not necessary because of the oxygen supply for the heterotrophic bacteria by microalgae and cyanobacteria resulted in extensive economies for investment costs and operating expenses compared to an aeration plant dimensioned for 1,000 pe. The specific technical application of the synergetic effect between photauto-/-photoheterotrophic organisms and heterotrophic bacteria decomposing COD in an algae reactor thus lead to an effective and low-priced decentral sewage treatment process according to the purpose of the project.

    While German rivers and streams as a rule have improved water quality, this doies not apply to lakes. Several German states have therefore developed strategies for pollutant elimination. A P elimination process is presented here in which a waste material, e.g. ferrihydrite, is used for lake regeneration. The end product can be utilized in agriculture. The method is also applicable for sludge removal.

Hinter dem hier vorgestellten P-Eliminierungsverfahren steht der Gedanke, dass dem Verwertungsgebot des Kreislaufwirtschaftsgesetzes entsprochen werden soll, indem ein Abfallprodukt wie Ferrihydrit im Bereich Seensanierung und -restaurierung eingesetzt wird und anschliessend im landwirtschaftlichen Bereich weiterverwertet werden kann. Darueber hinaus kann diese Verfahrenstechnik - ausgestattet mit bereits vorhandenen und fuer die P-Eliminierung auch notwendigen Schraegklaerern - alternativ bei der Entschlammung von Seen eingesetzt werden.

    Residual stresses can be result in both detrimental as well as beneficial consequences on the component's strength and lifetime. A most detailed knowledge of the residual stress state is a pre-requisite for the assessment of the component's performance. The mechanical methods for residual stress measurements are classified in non-destructive, destructive and semi-destructive methods. The two commonly used (semi-destructive) mechanical methods are the hole drilling and the ring core method. In the context of reactor safety research of the Federal Ministry of Economic Affairs and Energy (BMWi), two fundamental and interacting weak points of the hole drilling as well as of the ring core method are investigated. On the one hand, there are effects concerning geometrical boundary conditions of the components and on the other hand, there are influences of plasticity due to notch effects. Both aspects affect the released strain field, when the material is removed and finally, the calculated residual stresses. The first issue mentioned above is under the responsibility of Institute of Materials Engineering - Metallic Materials (Kassel University) and the last one will be investigated by University of Stuttgart-Otto-Graf-Institut - materials testing institute. Within the framework of this project it could be demonstrated that updated calibration coefficients lead to more reliable residual stress calculation in contrast to existing ones. These findings are valid for points of measurements on components without geometrical boundary effects like edges or shoulders. Reasons are high developed Finite-Element software packages and the opportunity of modelling the point of measurement (hole geometry, layout of the strain gauges) and its vicinity more in detail. Special challenges are multi-axial residual stress depth distributions and the geometry of components composing edges and claddings. Unlike existing analyses considering uni-axial and homogeneous stress states, bi-axial plane stress states were taken into account in this study. In the case of component's edges minor influences on the calculated stresses could be observed using standard calibration coefficients. Thus, a specific calibration is not considered necessary. The effects on shoulders could be assessed analogously. In the case of the claddings a remarkable influence could only be observed, if their thickness is below 2 mm. Essential benefits were reached through pre-experiments. As a consequence, the experimental execution was improved in terms of the material removal technique. The experimental data preparation was investigated in addition, which lead to the approach not to condition the experimental strains but rather the calculated stresses. This method is important for the experiments of phase 2 within this project. As a consequence of a successful project, the present knowledge base will be considerably improved and will be available for various engineering fields. Especially, the quantitative consideration of real residual stress states for optimized component designs will be feasible and finally the consequences of residual stresses an the component's safety, which are used in nuclear facilities, can be evaluated. The findings of the first numerical and theoretical research period (phase 1) at Kassel University are documented in this report.

    The findings obtained in recurrent inspections as a rule are evaluated by fracture-mechanical analyses. On the basis of the results, it is decided whether a component must be repaired or if operation can continue as it is for the time being. The two-criteria method is applied as a rule because of its universal applicability. Limited ductile crack growth can be taken into account if crack resistance curves are available that can be transferred to the component in question. In the investigations presented here, the influence of the relevant initial variables, e.g. strength coefficents, fracture-mechanical material coefficients, primary and secondary stresses and the intrinsic state of stress is illustrated by exemplary calculations. Further, the safety concepts underlying the assessment are gone into. (orig.)

    Shaping the developments of network-based supply systems is a difficult challenge in the context of preparing for the future. The structures for supplying the public with the basic goods electricity, gas and water, and also telecommunication services, have become the subject of public debates. A sustainable future for the supplies is being sought: measures for protecting the climate have been requested; citizens have committed themselves to opposing not only planned power stations, and coal mining, but also wind power plants; energy resources like coal, oil and natural gas are becoming scarce and expensive. At the same time, the supply utilities must meet the challenges of privatization, market openings and globalization. The pressure of high costs necessitates savings. The question is which choices are open within the framework of these determining factors. Setting the course for a sustainable future supply means that a method is needed for diagnosing the opportunities and risks of future developments as early as possible and for leveling out promising paths. The bases upon which decisions are made should be as transparent as possible and hence be easy to understand and put into action. lt is against this background that this study looks at specific options for the future and uses this as a basis for developing a method which tries to answer the question ''What is it that we want?''. It is not about an abstract discussion of the sustainability of future supplies or the contribution of specific technologies to sustainability, but about views of the future of supplies with respect to all societal aspects, with reference to which specific objectives are discussed, the pros and cons of which are weighed up, and regarding which the expected conflicts and potentials for reaching a consensus are leveled out. The essential features of this method are the multiple stages involved and the inclusion of science and society. Scientific and societal actors are involved in structured stages that build upon each other so that the elaborate opportunities and risks of different options for the future can be hammered out.

    At present, mainly biogas plants with liquid manure as basis substrate are operated in the Federal Republic of Germany. Since the introduction of the Renewable Energy Resources Act in the year 2004, regenerating raw materials dominate as co-substrate beside organic residual substances. In the context of the composite material ''Biogas Crops network '', the mono fermentation is examined of grass silage in a two-phase procedure guidance using bioleaching. Thus the turnover rate of the energy stored in the organic mass is to be increased to methane. The focus of the investigations lies on the improvement of the hydrolysis achievement. Despite the high methane formation in the hydrolysis stage, in the thermophilic hydrolysis the highest degree of degradation of oTS and the highest yields of methane are received in the overall system.

    The neutralisation of acidic open cast mining lakes is an important task at the restoration of post lignit mining landscapes in Lusatia and Middle Germany. From several treatment technologies for the manipulation of ground and surface waters the in-lake-treatment procedures are most cost effective, licensable and usable with passable risks to reach ecological targets. The proceedings and the results of a two-stage-treatment technology of the Horstteich near Luckau will be exemplified in this article. In this case it was possible, within 20 days, to improve the water quality from extreme acidic (pH {approx} 2.8) to neutral conditions (pH > 8). During the neutralisation nearly all heavy metals and suspended substances were precipitated and a noticeable buffer was built up against acidic inflows. (orig.)

    The purpose of the invention is to make the manufacture and the maintenance of a spherical mirror for a solar power station lowered into the ground simple and economical, even for large dimensions. According to the invention, this problem is solved by applying a hardening fixing layer to the surface of a prepared mould from one cantilever of a frame which can follow the spherical shape of the mirror, then spraying a transition layer onto this, and spraying a hardening elastic layer of foam on this, finally glueing the mirror layer on top. This process makes it possible to carry out fully automatic manufacture and maintenance of the spherical mirror from a frame. Foam may be added to the material forming the transition layer. (HWJ).

    Label free methods that do not require fluorescence markers or radioactive isotopes are of interest for high throughput screening applications. Thus, a new assay type for the RIfS technology was developed. These phosphorylation assay experiments were tested for reproducibility and were validated, initially using a single channel machine. The use of surface active materials to reduce or eliminate non specific binding is recommended. The non specific binding of the individual reagents was an important factor for their integration in the RIfS method. The immobilisation of binding reagents was tested using various methods. Since the various combinations are essentially limitless, they could not be explored to their full extent within the confines of this project. The application of the assay into microtitre plate format was not fully completed within the time frame allotted, however, has since been completed by one of the project participants as part of a further cooperation. Theoretically, this method is also suited to the robotics and sample throughput integral to a HTS system A comprehensive evaluation of RIfS technology regarding its entry into high throughput screening, however can only be made with reservation, due to the limited experience with its use in 96 and 384 microtitre plates.

    The increasing number of the world population results in a pronounced ascent of the world-wide energy consumption. This problem additionally is strengthened by the release of carbon dioxide. In the contribution under consideration, the author develops a method with which the yields of fermentation gas or methane, respectively, reliably as well as practice-orientated can be determined. Different influences on the determination of these yields are described. Thus, the investigations in this area are to be standardised further. The comparability under laboratories is to be increased.

    The practicability, safety and clinical efficacy of intracavitary therapy with Re-186-colloid in patients with recurrent otitis media and paranasal sinusitis, resistant to pharmacotherapy and surgical treatment is demonstrated based on a preliminary treatment trial. Methods: the authors report on a total of 39 applications of 5-35 MBq {sup 186}Re-colloid into the tympanon and the paranasal sinuses in six patients. Biodistribution and biokinetics were studied by gamma camera imaging. Clinical success was documented 6-20 months after therapy both by patients self-evaluation and by objective rhinootological follow-up, using a four-step score from -1 to+2. Results: no serious side effects were seen. There was good to excellent clinical improvement with a mean score of +1.44 {+-} 0.5 by patients self-evaluation and by physicians scoring of +0.81 {+-} 0.9 with only negligible extracranial tracer deposition. Conclusion: this novel treatment option using intracavitary application of Re-186-colloid in chronic otitis media and sinusitis is safe and effective. The term Radio-Tympano-Sinu-Orthesis (RTSO) might be proposed analogously to the well-known radiosynoviorthesis (RSO). (orig.)

    For reasons of economy and pollution control, aqueous lead-oxide-containing wastes from the various steps of lead storage battery production are reprocessed involving e.g. a vibrating screen for separating foreign matter and particles larger than 0.2 mm, dewatering of the residual paste by centrifuging for recycling the thickened product to the production process at an H/sub 2/O content of some 20 wt%. Largish particles separated by the screen can be re-used after being finely ground; the water may be recycled just as well or be discharged following neutralisation.

    The health-related evaluation of pollutants is a necessary basis for regulations in many sectors of environmental protection. It has been a concern of the Federal Ministry for the Environment, Nature and Nuclear Safty (Dessau-Rosslau, Federal Republic of Germany) to documentate and to describe the methods and procedures for health assessment of substances in environmental media. The compilation provides a comparison of methods with each other and especially with the derivation method of 'derived no-effect levels' according to the EU legislation on chemicals. In addition to the substantial compliance of the derivation methodology, the comparison shows differences in some aspects of the derivation methodology.

    The development as well as the validation of a gas mixing system (GMS) that enables dynamic and traceable production of stable long-term VOC gas mixtures within the range between a few {mu}g/m{sup 3} and a few 100 {mu}g/m{sup 3}, is discussed. In this method pure liquid substances that are filled into stainless steel bottles are kept separately at a constant temperature, evaporated according to their vapour pressure and removed by a small inert gas flow. They are finally united in a gas mixing chamber. The carrier gas must be as small as possible so that the quasi-equilibrium between the gas space and the liquid phase in the substance bottles will not be disturbed. The carrier gas is assumed to be saturated with substance gas due to a long residence time in the bottles and a fast phase transition. Any concentration level of the gas mixture can be generated by a combination of vaporization temperature, carrier and dilution gas flows. With the GMS a mixture of 25 VOCs was prepared. For 16 compounds stable and reproducible gas concentrations were realized. Due to not completely removed leakage of some substance bottles and the tubing respectively, variation of the concentration of the remaining compounds was found. A sink effect as another reason for this variation could be expelled and the chemical stability of the vaporized substances proved with the exception of some aldehydes. The procedure was successfully applied in a round robin test and a material test. In the latter adsorption of VOCs on building products was scrutinized. In this way the applicability of the GMS could be shown. (orig.)
