    Full Text Available Sportler aus Sportarten, in denen ein geringes Körpergewicht vorteilhaft für die Leistungsfähigkeit ist, gehen oft durch Reduktion der Kalorienzufuhr bei gleichzeitig hohem Energieverbrauch ein erhebliches Energiedefizit ein. Dabei kommt es häufig zu Essstörungen, für die in besonders gefährdeten Sportarten eine Prävalenz von bis zu 80 % berichtet wird und die sich zur Anorexia nervosa oder Bulimia nervosa entwickeln können. Als Folge des Energiedefizits können Konzentrationsänderungen von Stoffwechselhormonen, Störungen der Hypothalamus- Hypophysen-Gonaden-Achse und des Knochenstoffwechsels mit Abnahme der Knochendichte bis hin zur Osteoporose und einem erhöhten Risiko für Stressfrakturen beobachtet werden. Der Symptomkomplex aus Essstörung, sekundärer Amenorrhö und verminderter Knochendichte wird auch als „Female Athlete Triad“ bezeichnet, wobei in den vergangenen Jahren als viertes Symptom eine endotheliale Dysfunktion beschrieben wurde. Die effektivste Therapie ist das Herstellen eines dauerhaften Energiegleichgewichts, wofür eine tägliche Energieverfügbarkeit von mindestens 30 kcal/kg Magergewicht erforderlich ist. Eine hierdurch bedingte Gewichtszunahme kann den Sportlern nicht immer vermittelt werden, weshalb durch eine sorgfältig zusammengestellte Ernährung zumindest auf eine ausreichende Zufuhr von Kalzium, Vitamin D und Eiweiß geachtet werden muss. Oftmals ist die zusätzliche Verabreichung von Kalzium- und Vitamin-D-Präparaten angezeigt sowie eine Östrogensubstitution. Allerdings ist ein orales Kontrazeptivum als einzige Therapie – anders als früher angenommen – nicht ausreichend zur Behandlung oder Vermeidung einer Knochendichteminderung. Zur Prävention der Anorexia athletica sind die Aufklärung der Sportler, Trainer und Betreuer und ein Screening im Rahmen von Sporttauglichkeitsuntersuchungen, vor allem aber auch strukturelle Maßnahmen durch die Sportfachverbände erforderlich (wie zum Beispiel im

  7. Innovation durch Paradigmenwechsel - zur Bone Welding® Technologie

    Science.gov (United States)

    Mayer, Jörg; Plasonig, Gerhard

    Innovation entstand und entsteht in der Medizin häufig aus dem Bedürfnis des Klinikers heraus, bestehende chirurgische Techniken zu verbessern oder durch die Einführung neuer Methoden, chirurgische Zugänge zu ermöglichen, welche für den Patienten weniger traumatisch und für den Chirurgen technisch einfacher und damit sicherer sind. Historisch gesehen wurden Innovationen bis weit in die zweite Hälfte des 20. Jahrhunderts vor allem durch Kliniker angeregt und auch massgeblich mitentwickelt. Als illustrative Beispiele hierfür seien die heute immer noch führenden und auch kommerziell sehr erfolgreichen Entwicklungen von Osteosynthesetechniken und Implantaten durch die AO (Arbeitsgemeinschaft für Osteosynthesefragen) oder auch die Einführung endoskopischer Operationstechniken erwähnt.

    2006-07-01

    Full Text Available Die Mediendidaktik ist eine Teildisziplin der Medienpädagogik und hat in den vergangenen Jahren einen enormen Zuwachs an Nachfrage und Bedeutung erfahren. Dieser Bedeutungszuwachs ist bedingt durch den verstärkten Einsatz digitaler Informations- und Kommunikationstechniken in Bildungsprozessen (Stichwort «E- Learning». Der vorliegende Beitrag entwickelt die These, dass die Mediendidaktik ausgehend von medientechnischen Entwicklungen im Kontext von Globalisierung einer Entgrenzung unterworfen ist. Diese Entgrenzung ist Chance und Risiko zugleich. Der vorliegende Beitrag klärt zunächst den Begriff der Entgrenzung. Anhand dreier Phänomene werden Prozesse der Entgrenzung für die Mediendidaktik beschrieben. Ausgehend von der Problematisierung der Prozesse von Entgrenzung werden abschliessend einige Folgerungen für die Mediendidaktik als Teildisziplin der Medienpädagogik zur Diskussion gestellt.

  11. Amerikanisierung durch Internationalisierung: Die Expansion der International Communication Association (ICA

    2016-12-01

    Full Text Available Basierend auf der Soziologie Bourdieus problematisiert dieser Beitrag die Bemühungen der International Communication Association (ICA, sich über die Öffnung ihrer Führungsetage für Wissenschaftler außerhalb der USA in eine wahrhaft internationale Fachgesellschaft zu verwandeln und der Herausforderung einer global vernetzten Disziplin zu begegnen. Geleistet werden soll so ein kritischer Beitrag zur Selbstreflexion der Kommunikationswissenschaft, zu verstehen als Deutungsangebot und Ausgangspunkt für die wissenschaftliche Diskussion. Die Untersuchung von Habitus und Kapital der 29 ICA-Präsidenten und ICA Fellows aus der internationalen Scientific Community zeigt, dass die weltweit größte kommunikationswissenschaftliche Fachgesellschaft trotz der Ausweitung ihrer Führungsriege immer noch deutlichen US-Einflüssen unterliegt. Die neuen ICAWürdenträger, die für nationale und fachliche Vielfalt stehen sollen, stammen aus Weltregionen, die eine besondere Nähe zu den Vereinigten Staaten auszeichnet, und wurden an US-Universitäten sozialisiert oder stark von der US-amerikanischen Forschungstradition geprägt. Ausnahmen („Einkäufe“ von führenden Vertretern anderer Fachgesellschaften oder alternativer Paradigmen bestätigen die Regel. Die Internationalisierung der ICA-Führungsetage veränderte demzufolge weniger den Machtpol im Fach als vielmehr die Kommunikationswissenschaft weltweit. Zwar gelangten neue Perspektiven ins Zentrum der Disziplin. Im Gegenzug fand jedoch eine Amerikanisierung nationaler Felder statt, allen voran durch ICA Fellows als Vorbilder im Kampf um wissenschaftliches Kapital. Die Bemühungen der ICA, sich durch die Expansion ihrer Führungsriege zu internationalisieren, dürften somit die Machtstrukturen im Fach weiter verfestigt haben.

    2014-07-01

    Full Text Available Public Diplomacy stellt insbesondere für Staaten in internationalen Konflikten wie Israel ein wichtiges Kommunikationsinstrument dar, um ausländische Bevölkerungen zu erreichen. Der Artikel zeigt die Ergebnisse einer Studie, in der untersucht wurde, wie die israelische Public Diplomacy von deutschen Journalisten aufgenommen und verarbeitet wird. Journalisten kommt dabei eine Schlüsselrolle als Mittler zwischen dem israelischen Staat und der deutschen Bevölkerung zu. In Anlehnung an den Katalog der Public Diplomacy-Maßnahmen von Gilboa (2006 wurde die Relevanz einzelner Maßnahmen für Journalisten erfragt. Die Ergebnisse zeigen, dass persönliche Kontakte für Journalisten nach wie vor eine wichtige Quelle darstellen und nicht von Cyber-Public Diplomacy ersetzt werden können. Staatliche Public Diplomacy wird zwar wahrgenommen, jedoch wird ihre Objektivität bezweifelt, während NGOs und Stiftungen als vertrauenswürdiger eingestuft werden. Des Weiteren wird Israel in der Öffentlichkeit nach wie vor dominierend mit dem Nahostkonflikt identifiziert, was sich nach Meinung der befragten Journalisten auch in Zukunft nicht durch gezielte Öffentlichkeitsarbeit verhindern lässt.

    The implementation of material-specific residue treatment processes requires reconstruction measures both in the case of mechanical-biological and in that of thermal treatment plants. Such measures involves great uncertainties and wide variation in cost prediction. The present paper deals with various factors that influence the costs of residual waste treatment. [Deutsch] Zur Umsetzung der stoffspezifischen Restabfallbehandlung sind Anpassungen sowohl der derzeit betriebenen mechanisch-biologischen als auch der thermischen Anlagen erforderlich, was zu Unsicherheiten und grossen Schwankungsbreiten bei den Kostenprognosen fuehrt.

    Plant operations management systems, being IT application systems, provide integral support of the business processes making up plant operations management. The use of plant operations management systems improves mutually interdependent factors, such as high economic performance, high availability, and maximum safety. Since its commissioning in 1988, the Emsland nuclear power station (KKE) has been run with the IBFS plant operations management system. The work flow management system (WfMS), a module of IBFS, is described as an example of job order processing. IBFS-WfMS is to optimize all processes, thus cutting costs and ensuring that processes are run and documented reliably. Assessing the savings effect achieved through the use of IBFS-WfMS clearly reveals the savings in work/time achieved by the system. These savings are quoted as approx. 4 minutes and DM 10, respectively, per working step, which corresponds to several dozens of manyears or several million DM per annum in the KKE plant under consideration. This result can be extrapolated to other plants. (orig.) [German] Betriebsfuehrungssysteme stuetzen als EDV-Anwendungssystem integral die Geschaeftsprozesse der Kraftwerksbetriebsfuehrung. Durch den Einsatz von Betriebsfuehrungssystemen werden die in gegenseitiger Abhaengigkeit befindlichen Faktoren hohe Wirtschaftlichkeit, hohe Verfuegbarkeit und groesstmoegliche Sicherheit im Verbund gefoerdert. Im Kernkraftwerk Emsland (KKE) wird seit Inbetriebnahme der Anlage im Jahr 1988 das Betriebsfuehrungssystem IBFS eingesetzt. Am Beispiel des Workflowmanagementsystems (WfMS), einem Modul des IBFS, wird die Abwicklung von Arbeitsauftraegen dargestellt. Das IBFS-WfMS soll dabei durch Optimierung aller Prozesse sowohl kostensenkend wirken als auch sicherstellen, dass die Prozesse verlaesslich abgewickelt und dokumentiert werden. Eine Abschaetzung des Einspareffektes des IBFS-WfMS zeigt deutlich die durch das System erzielten Ersparnisse an Arbeits-/Zeitaufwand auf

    In a new process combination, nitrate-containing ground water is first of all separated by nanofiltration into a concentrate stream (some 25 %) and a largely nitrate-free permeate (75 %). Then the enriched nitrate in the concentrate is converted into nitrogen by means of electrocatalytic nitrate reduction. Whereas, in nanofiltration, a concentration takes place, electrocatalytic nitrate reduction is a process by which nitrate is converted into elemental nitrogen and, thus, removed. Nanofiltration is a membrane separating process making use of 'open' reverse osmosis membranes, which are characterized by high flow but also reduced retention. (orig.) [German] In einer neuen Verfahrenskombination wird das nitrathaltige Grundwasser zuerst durch Nanofiltration in einen Konzentratstrom (ca. 25%) und ein weitgehend nitratfreies Permeat (75%) aufgeteilt. Im Konzentrat wird dann mittels Elektrokatalytischer Nitratreduktion (EKN) das angereicherte Nitrat zu Stickstoff umgewandelt. Waehrend bei der Nanofiltration eine Aufkonzentrierung erfolgt, wird durch die Elektrokatalytische Nitratreduktion das Nitrat in elementaren Stickstoff umgewandelt und so entfernt. Die Nanofiltration ist ein Membrantrennverfahren, bei dem 'offene' Umkehrosmosemembranen eingesetzt werden, die einen hohen Fluss aber auch eine verminderte Rueckhaltung aufweisen. (orig.)

    The investigations showed that the LPS/IFN{gamma}-induced production of mediators by bone marrow macrophages was affected more significantly by PbCl{sub 2} in NOD mice, which are prone to autoimmunodiabetes, than in C57BL/6 mice. In NOD mice, the release of TNF{alpha} was enhanced by PbCl{sub 2} while the release of NO, PGE{sub 2}, MCP-1 and IL-12(p40) was decreased. The secretion of IL-12(p70) and IL-10 remained unmodulated. The PbCl{sub 2}-induced modulation of the pattern of secernated mediators can be interpreted as a shift towards an APC1 and maybe even a Th1 phenotype. The reduction of NO production in the presence of PbCl{sub 2} is assumed to be caused by the less pronounced expression of the gene of inducible NO synthase as the volume of specific mRNA measurable by RT-PCR was reduced. The enhanced production of TNF{alpha} is assumed to be due to an effect of PbCl{sub 2} on the protein kinase C dependent signal transducetion pathways. The hypotheses of a contribution of the expression of certain mHC molecules to the reactivity with PbCl{sub 2} could not be validated. The findings illustrate the immunomodulatory properties of the environmental pollutant PbCl{sub 2} and also the particular sensitivity of NOD mice. [German] In der vorliegenden Arbeit konnte gezeigt werden, dass die LPS/IFN{gamma}-induzierte Produktion von Mediatoren durch Knochenmarksmakrophagen aus genetisch zum Autoimmundiabetes praedisponierten NOD-Maeusen deutlich staerker durch Bleichlorid (PbCl{sub 2}) beeinflusst werden kann als bei C57BL/6-Maeusen. Bei NOD-Maeusen wurde die Freisetzung von TNF4{alpha} durch PbCl{sub 2} erhoeht, die Freisetzung von NO, PGE{sub 2}, MCP-1 und IL-12(p40) erniedrigt. Nicht moduliert wurde die Sekretion von IL-12(p70) und IL-10. Die durch PbCl{sub 2} ausgeloeste Modulation des Musters sezernierter Mediatoren kann als Verschiebung in Richtung eines APC1- und in der Folge moeglicherweise auch eines Th1-Phaenotyps gedeutet werden.

    Deposition of pollutants contained in fog to conifers is one important path of carry-over apart from wet deposition. In order to estimate deposition of pollutants from cloud water to conifer forests the liquid water content was registered at the Feldberg/Black Forest over a period of 21 months. A new sight- LWC-relation could be parametrised. With these parameters and the measured values of pollutants contained in fogs we calculated deposition of water quantities at several mountain stations. Fog water samples show higher concentration of pollutants than rainfall. Over a whole year concentrations of sulfate and nitrate when calculated for a uniform liquid water content show a peak in May. Comparative calculations of the flow of cloud water and contents on a forest of conifers were carried out for the period 1982-1991. In higher mountaneous regions deposition of trace substances though fog to needle trees was to be found to be as high as from rainfall. (orig./EW) [Deutsch] Die Stoffdeposition durch Nebelinterzeption auf Nadelbaeume stellt einen bedeutenden Eintragspfad neben der nassen Deposition dar. Zur Abschaetzung der Stoffdeposition durch Wolkentropfen auf Nadelwaelder wurde der Fluessigwassergehalt auf dem Feldberg/Schwarzwald ueber 21 Monate registriert. Aus diesen Daten wurde eine neue Sicht-LWC-Beziehung parametrisiert. Mit Hilfe dieser Parametrisierung und mit den Messwerten von Nebelinhaltsstoffen wurden Depositionsrechnungen der Wassermenge fuer mehrere Bergstationen durchgefuehrt. In Nebelwasserproben weisen die Inhaltsstoffe hoehere Konzentrationen auf als im Niederschlag. Im Jahresgang weisen die auf einen einheitlichen Fluessigwassergehalt umgerechneten Konzentrationen von Sulfat und Nitrat ein Maximum im Mai auf. Vergleichsrechnungen zum Fluss von Wolkenwasser und Inhaltsstoffen auf einen Nadelwald wurden fuer den Zeitraum 1982 - 1991 durchgefuehrt.

    The ever increasing requirements with respect to fuel consumption, emissions as well as safety and comfort necessitate ever increasing complex functionalities in the car. They are realized, as a rule, by a combination of mechanics, hydraulics, electrics/electronics and, more and more, software. In the past, the development of the various electric/electronic, mechanical or hydraulic components tended to happen at separate levels, nowadays the focus is more on a comprehensive approach to the overall system. In this context, the integrated development of 'mechatronic' components, including the respective software, leads to a targeted solution. (orig.)

    The fuel quality of maize plants is to be characterized by short, elementary and thermonalysis. The plants will be pyrolyzed in order to facilitate transport and storage. The formal kinetic parameters of three parallel reactions describing solid matter decomposition are defined by means of TG-DSC, and the reaction enthalpy is measured. Pyrolysis experiments in a rotary kiln converter in the kg range show a strong dependence of the product spectrum on process temperature. In particular, the pyrolysis gas yield increases with temperature at the expense of pyrolysis oil and water. (orig) [Deutsch] Zur energetischen Nutzung von Kulturpflanzen wird die brennstofftechnische Charakterisierung von Maispflanzen durch Kurz-, Elementar- und Thermoanalyse durchgefuehrt. Zur Reduzierung des Aufwands fuer Transport und Lagerung sollen die Pflanzen pyrolysiert weren. Mit Hilfe der TG-DSC werden formalkinetische Parameter von drei Parallelreaktionen zur Beschreibung der Feststoffzersetzung bestimmt und die Reaktionsenthalpie gemessen. Pyrolyseversuche in einem Drehrohrreaktor im Kilogramm-Massstab ergeben eine starke Abhaengigkeit des Produktspektrums von der Prozesstemperatur. Insbesondere steigt die Pyrolysegasausbeute auf Kosten der Bildung von Pyrolyseoel und Wasser mit der Temperatur stark an. (orig)

    In many areas with soft water (low water hardness), variations of degradation behaviour are noted in the biological cleaning of municipal and industrial waste water. The use of acidic precipitation agents and processes of biological ammonium oxidation (nitrification) reduce the acid capacity of water. Addition of lime in different forms can prevent this drop in acid capacity. As a new development in this field, lime hydrate can be added in dry form. This form of application dispenses with some of the elements normally installed at sewage treatment plants. Several examples demonstrate the advantages offered by this technique, especially the need for less metal salts to eliminate phosphate. (orig.) [German] In vielen Weichwassergebieten (geringer Wasserhaerte) treten bei der biologischen Reinigung von kommunalen und industriellen Abwaessern Schwankungen des Abbauverhaltens auf. Der Einsatz von sauren Faellmitteln und die Prozesse der biologischen Ammoniumoxidation (Nitrifikation) senken die Saeurekapazitaet des Wassers ab. Durch die Zugabe von Kalk in verschiedenen Dosierformen kann die Saeurekapazitaetsabsenkung verhindert werden. Eine neue Entwicklung auf diesem Gebiet ist die Trockendosierung von Kalkhydrat. Wesentliche Teile der sonst installierten Anlagentechnik sind bei dieser Art der Dosierung nicht mehr notwendig. Anhand von mehreren Beispielen wird erlaeutert, welche Vorteile dieses Verfahren bieten kann, insbesondere bei der Einsparung von Metallsalzen zur Phosphatentfernung. (orig.)

Ergebnisse: Eine SLND war bei 161 Patienten möglich. 32 Patienten (19,8 % zeigten Lymphknotenmetastasen. 39 % der Lymphknotenmetastasen fanden sich außerhalb des Standarddissektionsgebietes von Vasa iliaca externa und Fossa obturatoria. Schlußfolgerung: Die SLND im Rahmen einer RRP läßt sich mit akzeptablem Aufwand in den Routinebetrieb einer urologischen Klinik bei enger Kooperation mit Nuklearmediziner und Pathologen integrieren. Die Rate an identifizierten Lymphknotenmetastasen wird im Vergleich zur üblichen begrenzten pelvinen Lymphdissektion ohne SLN-Markierung deutlich erhöht.

    Based on the experience with the Thermoselect plant at Fondotoce, Italy (100 Mg/d), which was commissioned in 1992, a 225,000 Mg/a plant with three units (720 Mg/d) is being constructed at Karlsruhe, Germany. The plant is scheduled for commissioning in 1998. The contribution presents the product balance, the approved emission levels, and the energy uses envisaged for the Karlsruhe project. Final product quality data and energy yields illustrate the differences from conventional thermal processes. An ecobalance comparing the Thermoselect process with grate furnaces shows that water, soil and air pollution is much reduced by the new Termoselect process. Apart from high product quality, the plant also has the advantage of reduced dumping cost and no long-term ecological hazards. (orig./SR) [Deutsch] Auf Basis der grosstechnischen Erfahrung mit einer seit 1992 in Fondotoce (Italien) betriebenen THERMOSELECT-Anlage (Kapazitaet 100 Mg/d), Restmuell umweltgerecht zu behandeln, wird 1998 der Aufbau einer 225.000 Mg/a-Anlage mit 3 Linien (720 Mg/d) in Karlsruhe (Deutschland) abgeschlossen. Die Produktebilanz und die genehmigten Emissionswerte sind in dem Artikel belegt. Gezeigt wird die fuer das Projekt Karlsruhe vorgesehene Energienutzung. Die Endprodduktqualitaeten und die Energieausbeute verdeutlichen die Unterschiede zu bisherigen konventionellen thermischen Verfahren. Eine erarbeitete Oekobilanz mit einem Vergleich von THERMOSELECT und Rostfeuerung zeigt die deutlich geringe Belastung der Umweltkompartimente Wasser, Boden und Luft durch das neue THERMOSELECT-Verfahren. Neben hohen Produktqualitaeten wird - verglichen mit traditionellen Techniken - ein deutlich verringerter Entsorgungspreis erreicht, wobei gleichzeitig oekologische Belastungen auszuschliessen sind.

    The purpose of the present follow-up project was to examine the contamination with polycyclic aromatic hydrocarbons (PAH) of different anthropogenic urban soils including clay soils containing demolition waste, household waste, ash, and residues from a coking plant. A further task was to analyse, or infer from other part-projects, standard soil parameters such as organic carbon content, pH, and anion levels in order to clarify any relationships between PAH contamination and the more easily determinable soil characteristics. Furthermore, the sorption behaviour for PAH of selected anthropogenic urban soils was to be characterised by means of batch experiments. [Deutsch] Im Rahmen des Anschlussvorhabens sollte die Kontamination von anthropogenen Stadtboeden- darunter Truemmerschutt-, Hausmuell-, Asche- sowie Kokereilehmboden- durch polyzyklische aromatische Kohlenwasserstoffe (PAK) untersucht werden.

Das Sorptionsverhalten ausgewaehlter anthropogener Stadtboeden fuer PAK sollte durch Batchversuche charakterisiert werden. (orig./SR)

    Purpose: MR examinations may be necessary in patients under artificial ventilation. Possible imaging artifacts originating from ventilation tubing made from silicone are demonstrated. Materials and Methods: In silicone carbohydrate residues are bound to silicon atoms. In silicone gels they give strong signals in MR imaging. MR signals from more solid silicone rubber are only possible if the carbohydrate residues in the molecular chain retain a sufficient mobility. To investigate whether silicone tubes give signals in MR images, different tubes for ventilation made from silicone and polyester were examined at 1.5 T (Gyroscan ACS NT, Powertrak 6000 gradients) with MR imaging and spectroscopy (MRS: PRESS, TE = 20 ms; relaxation time measurements: MIXED sequence; imaging: FFE [gradient echo] and TSE sequences). Results: Using short TE ({<=} 4 ms), tubes and sockets made from silicone could be imaged with FFE and SE sequences. An SE sequence with a short TE = 4 ms provided a sufficient signal intensity to depict the tube clearly besides brain tissue of a volunteer. When foldover occured, the signal of the tube was projected onto the brain tissue. MR spectra confirmed that the image signal originated from the carbohydrate residues of the silicon molecule chains, not from residual water in the tube wall material. T{sub 2} determinations indicate a multiexponential relaxation including a large component with a short TE ({<=} 15 ms). Tubes made from a polyester elastomere did not show up in MR images. Conclusion: In MR images acquired with very short echo times silicone in ventilation tubes may produce significant artifacts. (orig.)

    In the framework of this thesis a combined method of ultrasound and nuclear-spin tomography is presented. Via ultrasound pulses by the sound-radiation force in liquids and tissue phantoms motions are generated, which depend on ther viscoelastic properties. This motions are made visible by a motion-sensitive tomograph sequence in the phase image of the tomograph in form of a phase change. The first measurements on simple phantoms and liquids are presented. [German] Im Rahmen dieser Arbeit wird eine kombinierte Methode aus Ultraschall und Kernspintomographie vorgestellt. Ueber Ultraschallpulse werden durch die Schallstrahlungskraft in Fluessigkeiten und Gewebephantomen Bewegungen erzeugt, die von den viskoelastischen Eigenschaften abhaengen. Diese Bewegungen werden mit einer bewegungssensitiven Tomographensequenz im Phasenbild des Tomographen in Form einer Phasenaenderung sichtbar gemacht. Die ersten Messungen an einfachen Phantomen und Fluessigkeiten werden praesentiert. (orig.)

    The bridging performance in respect to shrinkage gaps of ETICS is a subject of controversy. Practitioners point out good experience, calculative examinations, however, support the requirement of special tests prior to technical approval. Experiments at a half-timbered facade where an ETICS was applied to dry-out the wall confirm their bridging ability during the shrinkage of the wooden studs. Therefore a special bridging test is generally not necessary for an insulation thickness of 80 mm or more. (orig.) [Deutsch] Zur Frage der Ueberbrueckung von Bewegungsfugen durch Waermedaemmverbundsysteme gibt es unterschiedliche Meinungen: Die Anwender weisen auf gute Erfahrungen in der Praxis hin, rechnerische Untersuchungen lassen hingegen eine spezielle Ueberpruefung fuer zweckmaessig erscheinen, die bisher bei der Zulassung solcher Systeme gefordert worden ist. Untersuchungen an einem Fachwerk-Versuchshaus mit nachtraeglich aufgebrachtem Waermedaemmverbundsystem bestaetigen dessen fugenueberbrueckende Eigenschaft beim Schwinden des Fachwerkholzes. Demnach ist bei Daemmschichtdicken von mindestens 80 mm ein Nachweis der Fugenueberbrueckungs-Faehigkeit generell nicht erforderlich. (orig.)

    The aim of the project was to identify areas in households and the tertiary sector in which changes in behaviour could result in energy conservation and thus a reduction of greenhouse gas emissions, and to quantify the potentials for 1995, 2005 and 2020. A second focus was on the analysis and evaluation of programmes and instruments to realise the potentials. With literature evaluation, expert interviews, and a household servey potentials and further technical development have been identified. In sum, behavioural measures can contribute to the CO2 reduction by 64 million tons in 1995 in households and 27 in the commercial sector in which the potential decreases to 18 million tons in 2020 due to the autonomous technical development. Adequate promotion programmes can help to realise 20-30% of the potential by 2020. (orig.) [German] Ziel des Vorhabens war, im Sektor private Haushalte und Kleinverbrauch Bereiche zu identifizieren, in denen Verhaltensaenderungen zur Energieeinsparung fuehren koennen, und diese Potenziale fuer 1995, 2005 und 2020 zu quantifizieren. Darauf aufbauend waren Programme und Instrumente zur Umsetzung aufzuzeigen und zu bewerten. Gestuetzt auf Literaturrecherchen und Expertengespraeche wurden Einzelpotenziale, Rahmenbedingungen, Entwicklungstrends in der Technik und im Ausstattungsgrad ermittelt. Insgesamt koennten Verhaltensmassnahmen im Haushaltssektor die CO2-Emissionen im Basisjahr 1995 um 64 Mio, im Kleinverbrauch um 27 Mio t vermindern. Bis 2020 bleibt dieses Potenzial im Haushaltssektor in etwa gleich. Im Kleinverbrauch sinkt es infolge der autonomen Technikentwicklung auf 18 Mio t ab. Durch geeignete Programme koennen bis 2020 etwa 20-30% des Potenzials erreicht werden. (orig.)

    Novel forest decline is particularly pronounced in the area of the ridges of medium-range mountains. Whereas acid precipitation was viewed as its sole cause early on in the discussions, it turned out later that the impact of trace gases, too, contributes to the damaging of forests. This report wants to point out the importance of fog interception, which equally plays a part in the pollutant receipts of forests. The deposition of fog water to a forest stand depends very much on altitude, so that trace substance deposition, too, is to be expected to be dependent on altitude. By attempting to quantify this effect, the report helps to pinpoint areas of relevance of this deposition pathway (orig./KW) [Deutsch] Die neuartigen Waldschaeden sind in den Kammlagen der Mittelgebirge besonders ausgepraegt. Waehrend in der anfaenglichen Diskussion die sauren Niederschlaege als alleinige Ursache angesehen wurden, zeigte sich spaeter, dass auch Einwirkungen von Spurengasen zur Schaedigung des Waldes beitragen. Dieser Bericht soll auf die Bedeutung der Nebelinterzeption aufmerksam machen, die ebenfalls zum Schadstoffeintrag in den Wald beitraegt. Die Deposition von Wolkenwasser auf einen Waldbestand ist stark abhaengig von der Hoehenlage, in der sich der Waldbestand befindet, so dass auch eine Hoehenabhaengigkeit des Spurenstoffeintrages zu erwarten ist.

    Agriculture`s potential contribution to the energy supply of the ``town of the future`` through the conversion of biomass to energy, including biogas production, is a rather modest one. Supposing that the share of total renewable energy in Germany`s primary energy demand rises to approximately 4%, then the proportion of biomass from biotic raw materials especially produced for the purpose will at the most make up an eighth of this amount. Beyond this, biomass is burdened with other drawbacks such as low supply efficiency, limited availability, and weather-dependent reliability. On the other hand, biomass is well suited for conversion to solid, liquid, and gaseous fuels, including inexpensive ones with low energy density (solid fuels), mostly used for stationary heating applications, as well as more expensive ones such as liquid fuels with a high energy density for mobile applications in the automotive sector. Thanks to its capacity to regenerate, biomass is an inexhaustible resource. Moreover, its natural life cycle has a small impact on the environment. [Deutsch] Der Beitrag, den die Landwirtschaft durch energetische Nutzung von Biomasse, z.B. auch mit der Erzeugung von Biogas, zur Energieversorgung der `Stadt der Zukunft` leisten kann, nimmt sich bescheiden aus. Wird erwartet, dass innerhalb des naechsten Jahrzehnts der Anteil regenerativer Energien insgesamt auf etwa 4% des Primaerenergie-Verbrauchs Deutschlands ansteigen koennte, so duerfte Biomasse als speziell zur Energiegewinnung angebaute nachwachsende Rohstoffe mit bestensfalls 0,5 Prozentpunkten daran beteiligt sein. Es beduerfen darueber hinaus auch Nachteile, wie geringe Bereitstellungseffizienz, beschraenkte Verfuegbarkeit und witterungsabhaengige Zuverlaessigkeit, der Beachtung.

    Bei der (18) F-Fluordeoxyglucose-Positronenemissionstomographie/Computertomographie (FDG-PET/CT) ergeben sich häufig Zufallsbefunde. In der vorliegenden Studie konzentrierten wir uns auf mittels FDG-PET/CT erhaltene Zufallsbefunde bei Patienten mit kutanem Melanom und überprüften deren Relevanz hinsichtlich weiterer diagnostischer Maßnahmen und Interventionen. Die Krankenakten von 181 konsekutiven Melanom-Patienten wurden retrospektiv ausgewertet, um das Management von Zufallsbefunden zu dokumentieren. Der Schwerpunkt lag dabei auf den histologischen Befunden. Bei 33 von 181 (18 %) Patienten lagen 39 relevante Zufallsbefunde vor, und zwar im Kolorektalbereich (n = 15 Patienten), in der Schilddrüse (n = 8), der Prostata (n = 2), dem Bewegungsapparat (n = 2), in Lymphknoten (n = 2), der Parotis (n = 1), den Mandeln (n = 1), den Nieren (n = 1) und der Gallenblase (n = 1). Bei 25 Patienten schlossen sich weitere diagnostische Verfahren an, wobei in 21 Fällen ein klinisches Korrelat nachgewiesen wurde. Bei 16 von 21 Patienten ergab sich eine Neoplasie, darunter fünf maligne Läsionen (vier Kolonkarzinome und ein Prostatakarzinom). Die Malignome wurden frühzeitig diagnostiziert und in der Mehrzahl der Fälle erfolgreich entfernt. Der Einsatz der FDG-PET/CT als Routine-Diagnostik wird in den Leitlinien empfohlen und ist indiziert bei malignem Melanom ab Stadium IIC. In dieser Studie wurden auf effektive Weise ansonsten nicht erkannte Krebserkrankungen, insbesondere Kolonkarzinome, detektiert. In den meisten Fällen war eine frühe Intervention möglich. Zufallsbefunde durch FDG-PET/CT sollten, unter Berücksichtigung des Zustands und der Wünsche des Patienten, mit den geeigneten diagnostischen Maßnahmen abgeklärt werden. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

    The study was carried out within the framework of activities for testing means of direct determination of radioactivity levels in the human body due to incorporated, inhomogenously distributed radionuclides. A major task was to derive the average depth of activity distributions, particularly from photon radiation at energies below 500 keV, for the purpose of making suitable attenuation corrections. The paper presents two applicable methods which yield information on the mean depths of activity distributions, obtained through additional analyses of the energy spectra. The analyses are based on measuring the dependence of intensity of the Compton radiation on the length of pathways of the photons penetrating the soft tissue, or on measuring the energy-dependent absorption effects with photons. (orig./CB) [Deutsch] Im Rahmen der direkten Aktivitaetsbestimmung bei inhomogener Radionukliddeposition im menschlichen Koerper mittels Ganz- oder Teilkoerpermessanlagen im klinischen Bereich oder im Strahlenschutz sollte besonders bei Photonenstrahlung mit Energien von weniger als 500 keV eine Ermittlung der mittleren Tiefe der Aktivitaetsverteilung zur Schwaechungskorrektur erfolgen. Im klinischen Umfeld ist es haeufig moeglich, zur Tiefenkorrektur die mittlere Organtiefe und damit die schwaechende Gewebsschicht mittels Ultraschall zu bestimmen. Ergaenzend hierzu werden im Folgenden zwei Methoden vorgestellt, welche Aussagen ueber die mittlere Tiefe von Aktivitaetsverteilungen durch Gewinnung von Zusatzinformationen aus dem Energiespektrum im Rahmen von gamma-spektroskopischen Personenmessungen ermoeglichen. Dazu werden einerseits die Abhaengigkeit der Intensitaet der Comptonstrahlung von der Laenge der Wegstrecke von Photonen durch Weichgewebe und andererseits energieabhaengige Absorptionseffekte bei Photonen als Grundlage herangezogen.

    Ergebnissen verglichen. So wurden in Laborversuchen Randbedingungen fuer die Ammoniak-Synthese in Reformersystemen in Abhaengigkeit der Parameter N{sub 2}-Konzentration im Erdgas, Temperatur, verwendete Katalysatoren und Raumgeschwindigkeit (Lastabhaengigkeit) aufgezeigt. Ferner wurde auch die Wirkung von Ammoniak auf die einzelnen Katalysatoren eines Dampfreformers untersucht. Zielstellung des Projekts war es ein einfaches, in BZH integrierbares Reinigungsmodul zu entwickeln, welches Ammoniakspuren aus dem Produktgas von Reformierungsprozessen entfernt. Aufgrund der stark hydrophilen Eigenschaft von Ammoniak sollten Verfahren zur Loesung und Abscheiden von Ammoniak in fluessigem Wasser untersucht werden. Dazu wurden unterschiedliche Konzepte technisch realisiert und im Laborversuch auf ihre Tauglichkeit hin untersucht und bewertet. Hier wurden Grenzen der Umsetzbarkeit der Ammoniakentfernung durch Loesen und Abscheiden in fluessigem Wasser aufgezeigt und Moeglichkeiten zur Realisierung einer vollstaendigen Ammoniakentfernung erarbeitet. Mit Hilfe der erzielten Ergebnisse wurde ein optimiertes Labormuster eines Reinigungsmoduls entwickelt, das zum einen eine moeglichst vollstaendige Ammoniak-Reinigung erzielt und zum anderen auch die Produktgaskonditionierung hinsichtlich Temperatur und Feuchte fuer den Brennstoffzelleneinsatz ermoeglicht. Das Reinigungsmodul wurde schliesslich auf einem dafuer modifizierten Teststand mitsamt den dazu benoetigten Peripheriekomponenten vermessen.

    The poor condition of many heating systems is caused by a conflict of interest between investors and users. Landlords tended to opt for low investment cost, while the accompanying higher consumption cost was paid by their tenants. The only thing that has changed here is the fact that the 'secondary cost' has become a criterion for new tenants' decision to rent an apartment. Heat contracting may be a way out of the problem as contractors are interested in high-efficiency heating systems and optimally controlled operation. Heat contracting is a service concept of private and communal organisations that involves payment, construction and operation of a heating system by the contractor depending on the contracting model used. [German] Die relativ schlechte und veraltete heizungstechnische Ausruestung der Wohngebaeude in Deutschland ist auf den lange Jahre bestehenden Interessenkonflikt zwischen Investor und Nutzer im Mietwohnungsbau zurueckzufuehren. Durch die Umlagefaehigkeit der Heizkosten auf die Nutzer (Mieter) war der Gebaeudeeigentuemer i.d.R. bestrebt, eine Anlage zu guenstigen Investitionskosten zu erwerben. Die daraus resultierenden, relativ hoeheren Verbrauchskosten waren als Betriebskosten auf die Mieter umlegbar und belasteten den Vermieter nicht. An dieser Situation hat sich bis heute prinzipiell nichts geaendert; allerdings sind die Nebenkosten mit der Hauptkostenposition 'Heizkosten' zu einem Kriterium der Vermietbarkeit geworden, so dass der Vermieter heute die Kosten moeglichst niedrig halten muss. Ein Ausweg aus dem Interessenkonflikt und der neuen Vermietsituation koennte das Waerme-Contracting sein. Seitens des Contractors ist der Einsatz hocheffizienter Anlagentechnik und optimale, d.h. ueberwachte Betriebsbedingungen fuer einen wirtschaftlichen Erfolg unabdingbar.

    Full Text Available Drug-induced osteoporosis may occur as a side effect of many commonly prescribed drugs. This leads to a disturbance of bone remodelling, which ultimately results in a preponderance of bone loss and – as a consequence – in an increased incidence of bone fractures. Also, a drug-induced disturbance of the calcium metabolism may contribute to bone mineral loss. Glucocorticoids, thyroxine, depot-medroxyprogesterone acetate, aromatase inhibitors, GnRH agonists, thiazolidinediones, proton pump inhibitors, antiepileptic drugs, selective serotonin (and norepinephrine reuptake inhibitors, anticoagulants, loop diuretics, calcineurin inhibitors and antiretroviral active substances can lead to significant bone mineral loss in long-term use. A combination of several bone-toxic substances can potentially amplify the negative effect on bone. When applying the above mentioned drugs over a prolonged period, a possible effect on bone should always be taken into account, especially in older people. An osteological investigation with laboratory and bone densitometry or fracture risk assessment by FRAX is required. For prevention and therapy of drug-induced osteoporosis lifestyle measures, an adequate supply of calcium and vitamin D and optionally a specific osteoporosis treatment with bisphosphonates, denosumab or teriparatide are appropriate. p bKurzfassung/b: Eine durch Medikamente induzierte Osteoporose kann als Nebenwirkung bei vielen häufig verschriebenen Pharmaka auftreten.

    In this thesis polymer-metal nanocomposites were fabricated by simultaneous sputtering of silver and polymers from two independent magnetron sputtering sources. By the netted structure and the dielectric properties PTFE is suited for the use as matrix material. The metal content of the composite films was determined via the measurement of EDX intensities. The size of the nanoparticles was determined by means of TEM and XRD and lies in the range of 10 nm. The composite materials show at the percolation limit a sudden transition of the properties from polymer- to metal-like behaviour. The specific resistance decreases in a range between 35 and 40 % silver content by at least nine orders of magnitude. The optical properties change with the metal content. The absorption caused by plasmon resonance, which has at small filling degrees its maximum at about 000 nm and has an intense yellow colour of the composite material as consequence shifts with increasing silver content to longer wavelengths. The difference in the optical.behaviour of the nanocomposites and the pure polymers can be used for the fabrication of Bragg reflectors. Small changes in the metal content can in the polymer-silver nanocomposites in the range of the percolation threshold effect a drastic change in ther properties, by which applications as sensors are thinkable. [German] In dieser Arbeit wurden Polymer-Metall-Nanokomposite durch gleichzeitiges Sputtern von Silber und Polymeren aus zwei unabhaengigen Magnetron-Sputterquellen hergestellt.

Der Metallgehalt der Kompositfilme wurde ueber die Messung von EDX-Intensitaeten ermittelt. Die Groesse der Nanopartikel wurde mit Hilfe von TEM und XRD bestimmt und liegt im Bereich von 10 nm. Die Kompositmaterialien zeigen an der Perkolationsgrenze einen schlagartigen Uebergang der Eigenschaften vom polymer- zum metallaehnlichen Verhalten. Der

    Non-resonant microwave absorption has been proven as a highly sensitive method to screen for supraconductivity. Furthermore, in special cases the microstructure of the superconducting material, which is connected by Josephson junctions, can be determined. In single crystals the pinning potential can be measured and it has been demonstrated for the 123 material, that the critical current density is limited by the existence of non-superconducting layers. Decoration of superconducting thin films with stable paramagnetic molecules was utilized to measure the typical length scale of field inhomogenities at the surfaces. These inhomogenities are probably generated by growth inhomogenities characteristic for epitactic thin films. Their influence dominates the field variance expected for an ideal typ II superconductor. (orig.) [Deutsch] Nicht-resonante Mikrowellenabsorption ist ein hochempfindliches Verfahren, um Supraleitung nachzuweisen. Ueber diesen Nachweis hinaus kann in Einzelfaellen die Topologie von supraleitenden Bereichen, die durch Josephsonkontakte getrennt sind, bestimmt werden. In einkristallinem Material ist dann die Bestimmung des Pinningpotentials moeglich und fuer 123-Material konnte gezeigt werden, dass die kritische Stromdichte durch die Existenz nicht-supraleitender Bereiche begrenzt wird. An supraleitenden duennen Filmen ist es durch die Methode der Oberflaechendekoration mit paramagnetischen Spins gelungen, die typische Laengenscala von Feldinhomogenitaeten zu messen, die durch das ``Insel``-Wachstum epitaktischer Filme verursacht wird.

    This project was part of a German-French research co-operation and investigated the practicability to immobilize heavy metals by adding iron oxides to contaminated soils (harbour sediment, bracky marsh contaminated by emission of a zinc/lead smelter, alluvial Gley soil contaminated by mining activity). Pot and field trials were carried out using three different soils. Five iron bearing materials were added to the soil (1% pure Fe in soil dry matter): Red mud from Al-industry, Fe-precipitation sludge from drinking water treatment, bog iron ore, unused steel shot and steel shot waste from surface treatment of rolled steel plates. When mixed with the soil NH{sub 4}NO{sub 3} and DTPA extractable amounts of heavy metals and uptake by plants was markedly reduced. It was demonstrated that precipitated Fe-bearing sludge from drinking water treatment was a very effective material reducing the NH{sub 4}NO{sub 3} soluble amounts by 40-50% (DTPA 30-40%) in the pot tests while the uptake by plants was reduced by 40% and more. Heavy metals were strongly bound in a fixed order Cd>Pb>Zn>Cu and stayed immobilized until the end of project. Heavy metals were immobilized to a certain extent in field trials, but less effect was observed on concentration in plants and soil extracts compared with the pot tests. In practice the treatment should exceed the 1% pure Fe tested and the application should more homogeneously affect the soil layer where the plant roots mainly grow. (orig.)

    Hochschulprozesse in Lehre und Verwaltung erfordern durch die steigende Integration und IT-Unterstützung ein sogenanntes Business Alignment der IT und damit auch ein professionelleres IT-Service-Management (ITSM). Die IT Infrastructure Library (ITIL) mit ihrer Beschreibung von in der Praxis bewährten Prozessen hat sich zum de-facto Standard im ITSM etabliert. Ein solcher Prozess ist das Konfigurationsmanagement. Es bildet die IT-Infrastruktur als Konfigurationselemente und deren Beziehungen in einem Werkzeug, genannt Configuration Management Database (CMDB), ab und unterstützt so das ITSM. Dieser Bericht beschreibt die Erfahrungen mit der prototypischen Einführung einer CMDB an der Technischen Universität München.

    Within the framework of a project sponsored by EUREGIO, test series with the biological activation stages of a German and a Dutch sewage treatment plant each are carried out using different process concepts for the control of oxygen supply by fuzzy logic. As the currently available results demonstrate, the developed fuzzy-logic fields of characteristic curves permit establishing a stable and, thus, little energy-consuming process with optimum oxygen supply in comparison with conventional control.

    This edited collection shows that good parenthood is neither fixed nor stable. The contributors show how parenthood is equally done by men, women and children, in and through practices involving different normative guidelines. The book explores how normative layers of parenthood are constituted...... by notions such as good childhood, family ideals, national public health and educational strategies. The authors illustrate how different versions of parenthood coexist and how complex sets of actions are demanded to fulfil today’s expectations of parenthood in Western societies.

    Companies' community involvement turns out to be spatially relevant and-in many cases-to be focused on the near surroundings of the place of business. Some companies strategically align their involvement in order to systematically address local challenges. The essay at hand addresses the subject of corporate social responsibility from a local development perspective. Using the example of two family-owned enterprises based in Duisburg, Haniel and Grillo, it illustrates how socially committed companies can get involved with their local community by acting as good neighbours. Furthermore, it argues that socially committed companies can function as producers of space concerning matters of urban and local development. The specific local settings as well as the economic conditions of the local community serve as an explanatory background of the companies' involvement. The cases presented in this paper prove the firms' specific knowledge of local development needs and possibilities. This makes them qualified partners for local government actors and civil society actors. Thus, in the future, it is worth addressing corporate local responsibility from a governance point of view both in theory and in practice.

    In summarising the outcome of the present study it can be said spraying the agent on the oral mucous membrane once a day had an effect on the incidence of mucous membrane ulceration in the case of both placebo and dexpanthenol treatment. However, there was no significant difference between placebo and dexpanthenol treatment, the only finding being a slight prolongation of latency time through aloe vera. These experimental findings give good reason to critically reconsider the clinical use of dexpanthenol as a supportive treatment for the prevention of radiogenic mucositis enoralis following irradiation of tumours in the head and neck region. However thorough oral lavage is an effective means of moderating the irradiation response of the oral mucous membrane. [German] Zusammenfassend ist festzustellen, dass in den vorliegenden Versuchen mit einmal taeglichem Aufspruehen des Praeparates auf die Mundschleimhaut sowohl die Placebo - wie auch die Dexpanthenol-Behandlung die Inzidenz von Schleimhautulzerationen modifiziert hat; zwischen Placebo- und Dexpanthenol-Behandlung ergab sich jedoch kein signifikanter Unterschied. Lediglich eine geringe Verlaengerung der Latenzzeit durch Aloe vera war zu beobachten. Auf der Basis dieser experimentellen Ergebnisse muss der klinische Einsatz von Dexpanthenol im Rahmen der Supportivtherapie zur Prophylaxe der radiogenen Mucositis enoralis bei der Bestrahlung von Kopf-Hals-Tumoren kritisch ueberdacht werden. Regelmaessige, intensive Mundspuelungen sind jedoch ein probates Mittel zur Verminderung der Strahlenreaktion der Mundschleimhaut. (orig.)

    Organically polluted sewage water can be economically cleaned in an aerobic biological sewage treatment plant with upstream anaerobic as this saves activation volume and ventilation energy. This was demonstrated in the sewage treatment plant of the PWA in Redenfelden, where an anaerobic stage was installed which uses the BIOTHANE{sup R} process. The CARROUSEL-system of the anaerobic stage has proved a istself both in the PWA ans in municipal plants between 5000 to 100000 EW. It is a robust system with uncomplicated control which guarantees observance of maximum values and allows elimation of P and N. (orig.)

    A prerequisite for successful wet oxidation is very accurately tuned and carefully monitored process control. In the alternative, a decline in water quality is actually possible. In particular, earlier studies in the ozonification of landfill leachate encountered problems in reducing levels of AOX in the presence of halogenated hydrocarbons. Serious problems in process control may arise when ozone is conventionally added and forms bubbles in the presence of surface-active substances; this foam accumulates and is so persistent as to evade mechanical control. Since the formation of foam is directly due to gas bubbles carried in, bubble-free addition of ozone through a membrane may be a viable approach. (orig.) [German] Voraussetzung fuer den Erfolg einer Nassoxidation ist eine sehr genau eingestellte und sorgfaeltig ueberwachte Prozessfuehrung, da anderenfalls auch eine Verschlechterung der Wasserqualitaet eintreten kann; insbesondere haben sich hier bei frueheren Untersuchungen zur Ozonung von Deponiesickerwaessern Schwierigkeiten bei der Reduzierung des AOX-Wertes in Anwesenheit von halogenierten Kohlenwasserstoffen ergeben. Gravierende Schwierigkeiten in der Prozessfuehrung kann Schaum bereiten, der sich bei konventionellem Blaseneintrag des Ozons in Anwesenheit von oberflaechenaktiven Substanzen bildet, sich in der Anlage ansammelt und dabei so bestaendig ist, dass er auf mechanische Weise nicht zu kontrollieren ist. Da die Schaumbildung direkt auf die eingetragenen Gasblasen zurueckzufuehren ist, stellt der blasenfreie Eintrag von Ozon durch eine Membran einen moeglichen Loesungsansatz dar. (orig.)

    The present paper describes complex fuzzy systems for controlling nitrogen elimination at plants with topped denitrification. For the design and testing of the fuzzy systems, dynamic simulation calculations and experimental tests were carried out in a semi-technical pilot plant. The controlling fuzzy systems indicate the supposed oxygen values for individual tank areas and the most appropriate partitioning of the activated sludge tank (anoxic/aerobic zone) as a function of the input quantities used. It is established that, with the more flexible control behaviour, a more stable nitrogen elimination and, at the same time, a cut in the amount of air transferred to the system can be attained in comparison with a conventional control. (orig.) [German] Im Rahmen dieses Beitrags werden komplexe Fuzzy-Systeme zur Regelung der Stickstoffelimination in Anlagen mit vorgeschalteter Denitrifikation vorgestellt. Zum Entwurf und zur Erprobung der Fuzzy-Systeme wurden dynamische Simulationsrechnungen und experimentelle Untersuchungen an einer halbtechnischen Versuchsanlage durchgefuehrt. Die uebergeordneten Fuzzy-Systeme geben in Abhaengigkeit der verwendeten Eingangsgroessen Sauerstoffsollwerte fuer die einzelnen Beckenbereiche und die jeweils guenstigste Aufteilung des Belebungsbeckens (anoxische/aerobe Zone) vor. Die Ergebnisse zeigen, dass durch das flexible Reglerverhalten eine stabilere Stickstoffelimination und gleichzeitig eine Einsparung an eingetragener Luftmenge im Vergleich zu einem konventionellen Regelsystem erreicht werden kann.

    burning processes in the cement industry. To do justice to the steel and iron industry it also deals with fuel substitution in a natural gas fired cokeless cupola furnace. [Deutsch] Die energetische und die stoffliche Verwertung von Abfaellen ist ein bereits seit langem diskutiertes Thema. Dabei interessieren zunaechst die Fragestellungen im Zusammenhang mit dem jeweils spezifischen Einsatz wie z.B. bei der Co-Verbrennung von Klaerschlamm in Kraftwerksfeuerungen, der Substitution von Primaerbrennstoffen durch Kunststoffabfaelle beim Brennprozess in der Zementindustrie usw. Darueber hinaus wird weiter der Vergleich der jeweiligen Anwendung untereinander sowie die Gegenueberstellung mit den zum Stand der Technik gehoerenden thermischen Abfallbehandlungsverfahren diskutiert. Diese Verfahrensvergleiche muessen selbstverstaendlich unter Einbeziehung aller insgesamt erforderlichen Aufwendungen an Zusatzstoffen und Zusatzenergie mit gleichen Randbedingungen durchgefuehrt werden. Dabei sind u.a. die sich aus den spezifischen Eigenschaften der Abfallstoffe fuer den jeweiligen Anwendungsfall ergebenden Besonderheiten zu beruecksichtigen. Das betrifft insbesondere die Auswirkungen einer Substitution von Primaerbrennstoffen durch Ersatzbrennstoffe aus Abfaellen (Sekundaerbrennstoffe) z.B. bei einem Brennprozess auf die Waermeuebertragungsbedingungen, die Stroemungsverhaeltnisse und damit zusammenhaengend auf die Temperaturverteilungen, den Guttransport und den spezifischen Energieaufwand. Ersatzbrennstoffe muessen sich sowohl aus stofflicher Sicht als auch aus brennstoff- und waermetechnischer Sicht fuer eine Substitution eignen. In dem vorliegenden Beitrag wird insbesondere auf die Anforderungen an Abfaellen, die zur Substitution von Primaerbrennstoffen dienen aus brennstoff- und waermetechnischer Sicht eingegangen. Hierzu werden zunaechst kurz einige wesentliche Gesichtspunkte der Waermeuebertragung in Feuerungen und Industrieoefen eroertert. Wichtig fuer die Bewertung einer

    Heating systems which are equipped with high- efficiency boilers save energy because the energy content of the flue gases is utilized through flue gas condensation. Stainless steel is an important high-efficiency boiler material. The chromium and nickel concentrations of acid condensates from high- efficiency systems in waste water were analyzed. Stainless-steel samples were immersed in a model condensate over a period of 10 weeks. Fresh model condensates were prepared after one week and three weeks to measure metal dissolution as a function of time. The longer the samples were immersed the more did the nickel concentrations in the model concentrate decrease. Without exception, the concentrations were clearly below the maximum permissible values laid down in leaflet M 251 which is issued by Abwassertechnische Vereinigung e.V. The expected inadmissibly high nickel concentrations did not occur in the acid condensates. (orig.)

    Illegal shipment of waste as well as enforcement related to waste shipment have been regularly the centre of attention of public and professional debates and are also a topic of cross-national relations. In addition, the fear persists that by illegal waste shipments waste is treated in plants neither adapted to protect the environment and health nor having sufficient recuperation capabilities for precious raw materials. This project therefore intends to clarify the status quo of waste shipment inspections in the 16 federal states of Germany (Bundeslaender, in the following cited as states or federal states) to identify potential for development regarding the organisation and execution of inspections and to elaborate recommendations to optimise enforcement activities and further development of European and German legislative regulations. In order to optimise the enforcement of the European Waste Shipment Regulation (WSR) and the German Waste Shipment Act (AbfVerbrG), an adequate number of qualified personnel is necessary within all bodies involved into waste shipment inspections. Those bodies are namely the competent waste authorities, customs, police, the Federal Office for Transport of Goods (BAG), the Federal Railway Authority (EBA) and the prosecution offices. An adequate number of qualified personnel is not provided for in all states/authorities. This is also reflected in the number of transport and plant inspections which deviate between zero to a fixed number per year as well as being continuously performed and based occasion-/cause oriented inspections. Tangible means like access to IT-systems and the Internet should be provided for on-site inspections. Besides qualified and experienced personnel also IT-Systems have a relevant impact on the preselection of the entity to be inspected as well as for on-the-spot investigations. Therefore IT-System can increase the efficiency of inspections (inspections per time unit resp. exposure of illegal shipments per time

    In a two year research project the long-term storage of hydrogen as energy carrier has been assessed in detail for large renewable electricity quantities in underground storage caverns in Germany. Next to a regions analysis for potential storage sites, the benchmarking against other large scale storage concepts, a comparative and perspective analysis of alkaline and PEM-electrolysers also potential business cases for Power-to-Hydrogen in the mobility sector as well as for the chemical, electricity and natural gas industry have been analysed. [German] Durch den geplanten Ausbau der Stromerzeugung aus fluktuierenden, erneuerbaren Energien in Deutschland ruecken Speichertechnologien fuer elektrische Energie immer staerker in den Fokus des industriellen und politischen Interesses. Eine vielversprechende Moeglichkeit fuer eine Langzeitspeicherung bei hohen Anteilen von Wind- und Photovoltaikanlagen sind Speichertechnologien wie die Wasserstoffspeicherung mit Hilfe von Wasserelektrolyseuren. Diese koennen erneuerbaren Strom in grossen Mengen und bei entsprechender Steuerung selektiv in Zeiten mit hohem Dargebot z.B. an Windstrom chemisch speichern. Der gespeicherte Wasserstoff kann dann entweder zu einem spaeteren Zeitpunkt wieder rueckverstromt oder direkt stofflich verwertet werden, z.B. als Kraftstoff fuer den Verkehrssektor, als chemischer Rohstoff oder fuer den Hausenergiebereich durch Einspeisung in das Erdgastransportnetz. Thema der vorliegenden Studie sind Analysen und Planungen fuer die Erprobung des Gesamtsystems ''Wasserstoff-Elektrolyse-Speicherung'' in energiewirtschaftlich relevanten Dimensionen. Dazu werden mit einem neuen Ansatz techno-oekonomische Entwicklungspfade fuer Wasserstoff-Systeme unterschiedlicher Groesse und Technologien charakterisiert und technologische Risiken bei der Realisierung dieser Systeme identifiziert und bewertet.

    The aim of the project was to identify areas in households and the tertiary sector in which changes in behaviour could result in energy conservation and thus a reduction of greenhouse gas emissions, and to quantify the potentials for 1995, 2005 and 2020. A second focus was on the analysis and evaluation of programmes and instruments to realise the potentials. With literature evaluation, expert interviews, and a household servey potentials and further technical development have been identified. In sum, behavioural measures can contribute to the CO2 reduction by 64 million tons in 1995 in households and 27 in the commercial sector in which the potential decreases to 18 million tons in 2020 due to the autonomous technical development. Adequate promotion programmes can help to realise 20-30% of the potential by 2020. (orig.) [German] Ziel des Vorhabens war, im Sektor private Haushalte und Kleinverbrauch Bereiche zu identifizieren, in denen Verhaltensaenderungen zur Energieeinsparung fuehren koennen, und diese Potenziale fuer 1995, 2005 und 2020 zu quantifizieren. Darauf aufbauend waren Programme und Instrumente zur Umsetzung aufzuzeigen und zu bewerten. Gestuetzt auf Literaturrecherchen und Expertengespraeche wurden Einzelpotenziale, Rahmenbedingungen, Entwicklungstrends in der Technik und im Ausstattungsgrad ermittelt. Insgesamt koennten Verhaltensmassnahmen im Haushaltssektor die CO2-Emissionen im Basisjahr 1995 um 64 Mio, im Kleinverbrauch um 27 Mio t vermindern. Bis 2020 bleibt dieses Potenzial im Haushaltssektor in etwa gleich. Im Kleinverbrauch sinkt es infolge der autonomen Technikentwicklung auf 18 Mio t ab. Durch geeignete Programme koennen bis 2020 etwa 20-30% des Potenzials erreicht werden. (orig.)

    Two studies on the subject of 'Climate Protection through Reduction of No-load Losses in Electric Applicances and Equipment' have been performed on behalf of the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety and the German Federal Environmental Agency. The first study, carried out by the Tuebingen-based engineering bureau eboek, has been published in the Federal Environmental Agency's TEXTE series (Texte 45/97, 2{sup nd} edition, 1998). It was the starting point for a multitude of activities among them two information campaigns carried out in 1998 and 1999 that were funded by the Federal Ministry for the Environment and the German Section of the Friends of the Earth (BUND). The study also served as a basis for decisions taken by the German Bundestag and the Bundesrat (Council of Constituent States). The second study on the subject was carried out by the engineering bureau eboek and Energiestiftung Schleswig-Holstein. Building on the results obtained in the first study, it presents estimates of relevant data for the European Union and examines various approaches for possible measures to reduce no-load losses as to their suitability. The studies impressively show that effective climate protection can be achieved in all relevant sectors, and in many cases even save costs. The results are detailed below. (orig.)

    Network monitoring of extensive water distribution systems as you can find in rural areas causes high costs. Therefore a current research project tries to find cost savings by using automatic meter reading of main flow meters within the network. The project focuses on improving leakage control as well as optimizing rehabilitation investments. By operation of a pilot plant significant potentialities for cost savings already could be identified. Additionally the calculation of the optimal time of rehabilitation shows that automatic meter reading is able to reduce investment costs. For the calculation of the costs the research team developed a software that supports the user in this decision making process. (orig.) [German] In grossraeumigen Wasserversorgungsnetzen, wie sie vor allem im laendlichen Raum anzutreffen sind, ist die Netzueberwachung mit erheblichem Aufwand verbunden. In einem laufenden Forschungsvorhaben wird untersucht, inwieweit sich Einsparungen durch Einsatz von fernablesbaren Grosswasserzaehlern realisieren lassen. Im Zentrum steht dabei die Verbesserung der Leckageueberwachung sowie eine Optimierung der Reinvestitionsplanung. Anhand ausgewaehlter Untersuchungsgebiete des beteiligten Wasserversorgers konnten bereits eindeutige Einsparpotenziale im Netz- und Leckagenmanagement durch den Einsatz der Fernablesung nachgewiesen werden. Auch die Berechnung des betriebswirtschaftlich optimalen Reinvestitionszeitpunkts laesst darauf schliessen, dass der Einsatz der Fernablesung zu einer Kostenreduktion fuehrt. Zur Berechnung der Kosten wurde eine Software entwickelt, die den Anwender bei seiner Entscheidungsfindung unterstuetzt. (orig.)

    A major issue in radiation protection is to protect the population from the harmful effects of exposure to radon and radon progeny. Quantification of the lung cancer risk emanating from exposure to radon decay products in residential and working environments poses problems, as epidemiologic studies yield information deviating from the results obtained by the indirect method of assessment based on dosimetric respiratory tract models. One important task of the publication here was to characterize the various exposure conditions and to quantify uncertainties that may result from application of the ``dose conversion convention``. A special aerosol spectrometer was therefore designed and built in order to measure the size distributions of the short-lived radon decay products in the range between 0.5 nm and 10 000 nm. The aerosol spectrometer consists of a three-step diffusion battery with wire nets, an 11-step BERNER impactor, and a detector system with twelve large-surface proportional detectors. From the measured size distributions, dose conversion coefficients, E/P{sup eq}, were calculated using the PC software RADEP; the RADEP program was developed by BIRCHALL and JAMES and is based on the respiratory tract model of the ICRP. The E/P{sup eq} coefficients indicate the effective dose E per unit exposure P{sup eq} to radon decay products.

Eine wichtige Aufgabe der vorliegenden Arbeit war es, unterschiedliche Expositionsbedingungen zu charakterisieren und die Unsicherheiten zu quantifizieren, die sich aus der

Dieses natuerliche Bioleaching, welches unkontrolliert ein Gefahrenpotential fuer die Umwelt darstellt, soll durch Aktivierung der autochthonen schwefeloxidierenden Bakterien (z.B. Thiobacilli) beschleunigt und zur Reinigung der Sedimente genutzt werden. Ziel ist es, ein naturnahes Verfahren zur Sedimentdekontamination unter Nutzung des natuerlichen biologischen Solubilisierungspotentials bereitzustellen. Die gereinigten Sedimente sollen in den Stoffkreislauf als Bodensubstrat zurueckgefuehrt werden. Die Verfahrensentwicklung erfolgte am Beispiel von hochbelasteten Sedimenten der Weissen Elster aus dem Suedraum Leipzig. Aus oekonomischen Gruenden soll das Bioleaching der Schwermetalle durch Festbettlaugung nach dem Perkolationsprinzip erfolgen. Das Verfahren erfordert mehrere Prozessstufen. Der Schwerpunkt der Untersuchungen im Labor- und Technikumsmassstab lag auf der Erarbeitung und technischen Umsetzung von Massnahmen zur Beschleunigung der Metallsolubilisierung. (orig.)

    Full Text Available This paper demonstrates the extent to which the media and belonging in Africa are torn between competing and often conflicting claims of bounded and flexible ideas of culture and identity. It draws on studies of xenophobia in Cameroon and South Africa, inspired by the resilience of the politicization of culture and identity, to discuss the hierarchies and inequalities that underpin political, economic and social citizenship in Africa and the world over, and the role of the media in the production, enforcement and contestation of these hierarchies and inequalities. In any country with liberal democratic aspirations or pretensions, the media are expected to promote national citizenship and its emphasis on large-scale, assimilationist and territorially bounded belonging, while turning a blind eye to those who fall through the cracks as a result of racism and/or ethnicity. Little wonder that such an exclusionary articulation of citizenship is facing formidable challenges from its inherent contradictions and closures, and from an upsurge in the politics of recognition and representation by small-scale communities claiming autochthony at a historical juncture where the rhetoric espouses flexible mobility, postmodern flux and discontinuity. Der vorliegende Beitrag zeigt auf, inwieweit die Medien und gesellschaftliche Bindungen in Afrika zwischen konfligierenden Ansprüchen abgegrenzter und sich wandelnder kultureller Identitäten zerrissen sind. Angeregt durch die Erfahrung der kontinuierlichen Politisierung kultureller und sozialer Identitäten zieht der Autor Studien zu Fremdenfeindlichkeit in Kamerun und Südafrika heran, um die Hierarchien und Ungleichheiten zu diskutieren, auf denen politische, wirtschaftliche und soziale Staatsbürgerschaft in Afrika und darüber hinaus basiert, sowie die Rolle der Medien bei der Entstehung, Verstärkung und im Wettstreit dieser Hierarchien und Ungleichheiten.

    Pyrite (FeS{sub 2}) oxidation due to open-pit lignite mining activities may result in acid mine drainage and dissolved metals in the soil and ground water of the overburden spoil piles. The pyrite oxidation takes place firstly during the mining process and at the temporary surfaces of the mine, secondly in deep zones of the overburden spoil pile as a result of gas transport through the unsaturated zone. The second process continues after mine closure possibly over several decades and therefore contaminates the environment for a long time. Whereas some studies deal with a minimisation by geochemical means, this research focuses on a minimisation by impacting the physical boundary conditions. Special attention is given to the transport of oxygen from the soil surface to the pyrite oxidation zone. Soil column experiments with columns of 2.90 m height yield experimental data concerning the pyrite oxidation and the related transport processes in the unsaturated zone. Experimental data are compared to simulation results obtained with the model MUSIC; it calculates coupled reaction and transport processes in a one-dimensional soil profile using the finite volume method. Pyrite oxidation is described by means of a first order kinetics, the gas transport takes place by diffusion as well as convection. The transport of solutes in the soil water is described by the convection-dispersion equation (Cl{sup -}, Fe{sup 2+} and SO{sub 4}{sup 2-}). The simulations are able to reproduce the measured time series of oxygen concentrations in the soil profile. (orig.)

    SO{sub 2} fumigation (0.86 mg/m{sup 3}) reduced drastically the survival expectancy of spruce seedlings already after 1 month. Under such conditions, the infection of spruce by Armillaria ostoyae is known to increase. The present investigation has shown that mortality increased strongly by combining A. ostoyae infection and fumigation. However, mycorrhization of spruce (Paxillus involutus) increased the survival rate of seedlings and reduced infection by A. ostoyae remarkably (20%). (orig.)

    A data base on highly aromatic mineral oils has been compiled to classify mineral oil products according to their water-pollution potential (water hazard class or Wassergefaehrdungsklasse, WGK). This activity has been undertaken through the Commission for Water Hazardous Materials (Kommission Bewertung Wassergefaehrdender Stoffe, KBwS). In this special case, highly aromatic mineral oils containing a high concentration of polycyclic aromatic hydrocarbons (Polyaromatische Kohlenwasserstoffe, PAK) were evaluated. A test method for measuring the elution potential of PAK into water was developed on petroleum products with high viscosity and high freeze point. This method was applied to determine the solubility of 23 PAK (including 16 PAK according to EPA 610 and 6 PAK according to the German drinking water regulation (Trinkwasserverordnung, TVO)) from heavy fuel oil and neutral oil extract in the aqueous phase. For the 6 PAK, according to TVO, a sum limit of 0,2 {mu}g/l in drinking water is permitted by German legislation. This limit was not exceeded in any of the water phases examined. (orig.) [Deutsch] Fuer die Einstufung von Mineraloelprodukten in die Wassergefaehrdungsklassen (WGK) durch die Kommission Bewertung Wassergefaehrdender Stoffe ist es notwendig, Basisdaten zur Verfuegung zu stellen. Im speziellen Fall handelt es sich um die Bewertung von Mineraloelen, die sich durch einen hohen Gehalt an polycyclischen aromatischen Kohlenwasserstoffen (PAK) auszeichnen. Zur Eluierbarkeit von PAK`s aus Produkten mit hoher Viskosiaet bzw. mit hohem Stockpunkt wurde eine Pruefmethode entwickelt. Diese Methode wurde zur Bestimmung der Loeslichkeit von 23 PAK`s (16 PAK`s nach EPA-Liste incl. 6 PAK`s der TVO) aus den Mineraloelen Heizoel Schwer und Neutralextrakt in der Wasserphase eingesetzt. Fuer die PAK der TVO ist in der TVO ein Summengrenzwert von 0,2 {mu}g/l Trinkwasser angegeben. Dieser Grenzwert wurde in keiner der untersuchten Wasserphasen ueberschritten. (orig.)

  13. Organizing Patient Involvement

    Patient involvement has become a part of the political agenda in Danish healthcare. Patients are to be involved not only in questions and decisions relating to their own treatment and care – to involve patients in quality improvement has also become a political expectation of quality work in Danish...... hospitals. During the last 25 years, patient involvement and quality improvement have become connected in Danish healthcare policy. However, the ideal of involving patients in quality improvement is described in very general terms and with only few specific expectations of how it is to be carried out...... in practice, as I show in the thesis. In the patient involvement literature, the difficulties of getting patient involvement in quality improvement to have in an impact on the planning and development of healthcare services is, for example, ascribed to conceptual vagueness of patient involvement, differences...

    Patienten durch die Transmissionsmessung mittels Einzelphotonenquellen bei der PET. Material und Methode: Zwei Cs-137-Punktquellen (E{gamma}=662 keV, A=614 MBq) werden zur Transmissionsmessung im Einzelphotonenmodus an einem 3D-Scanner (ECAT ART) eingesetzt. Bei der Simulation einer Ganzkoerper-Transmission (axiale Laenge: 75 cm, 6 ueberlappende Bettpositionen), werden Dosismessungen mit Thermolumineszenzdosimetern unter Verwendung eines Thorax- und eines Abdomenphantoms durchgefuehrt. Aus den Messwerten wurde in Anlehnung an den Report Nr. 60 der ICRP die effektive Dosis fuer die Transmissionsmessung abgeschaetzt. Ergebnisse: Bei einer Gesamtaufnahmedauer von 360 min (60 min pro Bettposition) ergaben sich folgende Energiedosen: Oberflaeche (Xyphoid) 189 {mu}Gy, Herz 196 {mu}Gy, Lunge 234 {mu}Gy, BWS 240 {mu}Gy, Niere 207 {mu}Gy, Leber 204 {mu}Gy, Gonaden 205 {mu}Gy, Schilddruese 249 {mu}Gy und Blase 185 {mu}Gy, aus denen sich ein Konversionsfaktor von 1,7*10{sup -4} mSv/(h*MBq) errechnete. Die Abschaetzung der effektiven Dosis fuer den Patienten aufgrund einer Transmissionsmessung (Akquisitionszeit von 3,2 min pro Bettposition) ergab einen Wert von 11 {mu}Sv. Die Abschaetzung des Verhaeltnisses der Konversionsfaktoren durch Transmissionsmessung im Einzelphotonen- und im Koinzidenzmodus (zwei Ge-68/Ga-68-Linienquellen mit jeweils 40 MBq) ergab einen Wert von 0,18. Der Vergleich zwischen den effektiven Dosen durch die Transmission im Einzelphotonen-Modus und die Emission (bei Injektion von 250 MBq FDG) ergab ein Verhaeltnis von 2,3*10{sup -3}. Schlussfolgerung: Die Strahlenexposition der Patienten durch die Transmissionsmessung in der 3D-PET ist vernachlaessigbar gering. Sie wird durch die Verwendung der Einzelphotonenmethode mit kollimierten Punktquellen relativ hoher Aktivitaet im Vergleich zur Koinzidenzmethode mit nicht-kollimierten Linienquellen relativ niedriger Aktivitaet weiter reduziert.

  17. Doctors' involvement in torture.

    Jesper, Sonntag

    2008-01-01

    Doctors from both non-democratic and democratic countries are involved in torture. The majority of doctors involved in torture are doctors at risk. Doctors at risk might compromise their ethical duty towards patients for the following possible reasons: individual factors (such as career, economic or ideological reasons), threats, orders from a higher ranking officer, political initiatives, working in atrocity-producing situations or dual loyalty. In dual loyalty conflicts, factors that might compromise doctors' ethical obligations towards detainees/patients are: ideological totalitarianism, moral disengagement, victim blame, patriotism, individual factors or threats. Another important reason why doctors are involved in torture is that not all doctors are trained in addressing human rights issues of detainees. Torture survivors report that they have experienced doctors' involvement in torture and doctors themselves report that they have been involved in torture. Testimonies from both torture survivors and doctors demonstrate that the most common way doctors are involved is in the diagnosis/medical examination of torture survivors/prisoners. And it is common before, during and after torture. Both torture survivors and doctors state that doctors are involved during torture by treatment and direct participation. Doctors also falsify journals, certificates and reports. When doctors are involved in torture it has devastating consequences for both torture survivors and doctors. The consequences for the survivors can be mistrust of doctors, avoidance of seeking doctors' help and nightmares involving doctors. Mistrust and avoidance of doctors could be especially fatal to the survivor, as it could mean a survivor who is ill may not seek medical attention. When the unambiguous role of the doctor as the protector and helper of people is questioned, it affects the medical profession all over the world.

    Full Text Available Individuals with Disabilities Education Act (IDEA gives many rights to parents with special needs in terms of involvement and participation. Given the importance of family involvement in the special education process, and federal legislation that increasingly mandated and supported such involvement over time, considerable research has focused on the multiple ways that relationships between schools and families in the special education decision making process have played out. Educational professionals should create a positive climate for CLD families so that they feel more comfortable and therefore are able to participate more authentically and meaningfully.

    In a polluted soil of an abandoned gas works site, pure bacterial cultures were isolated which were able to degrade phenol, the three cresol isomers, and 2,3-, 2,4- and 3,4-xylenol. There were also mixed populations which degraded 2,5- and 3,5-xylenol. There were no bacteria in this soil which were able to degrade 2,6-xylenol. In spite of this, it was possible for the first time to decompose 2,6-xylenol using a mixed population of three different bacterial strains from other soils. One of these was a strain identified as Myeobacterium spec.SR18 which used 2,6-xylenol as its sole source of C and energy. (orig./EF). [Deutsch] Aus einem mit Schadstoffen kontaminierten Boden eines ehemaligen Gaswerkgelaeaendes konnten Reinkulturen isoliert werden, die in der Lage waren Phenol, die drei Kresolisomere und 2,3-, 2,4- und 3,4-Xylenol abzubauen. Ein 2,5- und 3,5-Xylenolabbau durch Mischpopulationen wurde ebenfalls beobachtet. Dagegen konnten aus diesem Boden keine 2,6-Xylenol-Abbauer gewonnen werden. Der bisher erst einmal beschriebene 2,6-Xylenolabbau gelang schliesslich mit einer weiteren, aus anderen verunreinigten Standorten angereicherten, Mischpopulation, die aus drei verschiedenen Bakterienstaemmen bestand. Darunter befand sich auch ein als Mycobacterium spec.SR18 identifizierter Stamm, der 2,6-Xylenol als alleinige C- und Energiequelle verwertet. (orig./EF).

    Full Text Available Für die Medienpädagogik ist wie für jede Pädagogik das Theorie-Praxis-Problem relevant. Im Beitrag wird partizipative Aktionsforschung als Methode zur Gestaltung von Theorie-Praxis-Korrelationen untersucht. Dazu wird zunächst das Theorie-Praxis-Problem als Relation der Korrelationen zwischen Theorie und Praxis in Forschungs- und Unterrichtsmethoden bestimmt. Anschließend wird durch Interpretationen von Theorien zur partizipativen Aktionsforschung und von Daten aus einem Projekt untersucht, ob die Relation von Forschung und Unterricht so gestaltet werden kann, dass zu souveränen Akten in solidarisch-libertären Gemeinschaften aufgefordert wird. Die Ergebnisse zeigen, dass dies möglich und die Methode also medienpädagogisch relevant ist. As for any education, the theory-practice transformation problem is relevant for media education. In this paper, participatory action research is investigated as a method to design the correlation of theory and practice. To do so, the theory-practice problem is understood as the relation of the correlations between theory and practice in research and teaching methods. Subsequently, it is researched if the relation of research and teaching can be designed to call for sovereign acts in solidary-libertarian communities. The research is conducted by interpreting participatory action research theories and project data. It is shown that it is possible to call for sovereign acts. Thus the suggested method can be considered as relevant for media education.

    We reported about intrathoracic changes and prognosis of 686 patients with sarcoidosis diagnosed in our hospital between 1963 and 1988. We evaluated CT findings in 135 patients with sarcoidosis and found pulmonary involvements in 81. We analyzed CT findings according to the classification by Tuengerthal which classified radiographic findings combining ILO classification of pneumoconiosis and characteristic findings of bronchovascular sheath with sarcoidosis. The CT findings were as follows: small opacities (44 out of 81 cases, 54.3%), large opacities (37 cases, 46.7%). Additional findings were as follows: peribronchial marking (42 cases, 51.9%), contraction (17 cases, 21.0%), pleural involvement (9 cases, 11.1%), bulla (5 cases, 6.2%). The characteristic CT findings of serious sarcoidosis were extasis of bronchus, thickening of the bronchial wall, unclearness of vascular shadow, atelectasis and thickening of pleura. Concerning the prognosis of pulmonary involvement, according to age, patients younger than 30 years old at initial diagnosis were better than those of 30 years and over in terms of disappearance of pulmonary involvements. According to stage, patients of stage I and stage II were better than those of stage III. Among the patients we were able to observe chest X-ray findings during five years according to the character of shadow, ill-defined shadow of small opacities and rounded shadows of large opacities had a higher disappearance rate of pulmonary involvements than irregular shadows of large opacities, atelectasis and contraction.

    In response to continually increasing electricity prices, production plants with electrical systems are using intelligent energy management systems (EMS). These reduce the power of, or even switch off, individual systems for a limited time in order to ease electricity use - without influencing production. In the forging shops, induction heaters should be used in such a management concept as the main recipient of electrical power yet this often involves production losses. In contrast, the use of zone heaters offers the opportunity to manage the heating process in the best way possible - even with strongly reduced output - so that there are no parts which have been heated incorrectly which could disturb production. Ruhrtaler Gesenkschmiede has installed two, from mid 2008 three, induction zone heaters. These have a total power of 4,500 kW, the operation of which enables a considerable reduction in the power maximum and, with this, also the electricity costs. (orig.)

    Maenner erkranken. Wir untersuchten die radiogene Hodenbelastung durch Streustrahlung bei adjuvanter Beckenbestrahlung nach Operation eines Rektumkarzinoms. Die gemessenen Strahlendosen am Hoden wurden zu den Daten der Literatur in Beziehung gesetzt. Patienten und Methode: Wir fuehrten bei 18 Patienten mit thermolumineszenzdetektoren (TLD) In-vivo-Messungen zur Bestimmung der streustrahlenbedingten Gonadendosis durch. Die TLDs wurden an vier definierten Punkten des Skrotums fixiert. Die Bestrahlung erfolgte 3-D-geplant in Drei-Felder-Technik in Bauchlage im Lochbrett. Die Gesamtdosis betrug 50,4 Gy, die Einzeldosis 1,8 Gy taeglich. Nach 45 Gy erfolgte eine Modifikation der Bestrahlungstechnik auf opponierende und kranial verkuerzte Gegenfelder zur kompletten Duenndarmschonung. Ergebnisse: Die mittlere Gonadendosis aller 18 Patienten pro Bestrahlungsfraktion betrug 0,057 Gy (median 0,05 Gy), wobei die Mittelwerte der einzelnen Patienten zwischen 0,035 und 0,114 Gy lagen. Die Standardabweichung betrug 0,02 Gy. Nach 28 Fraktionen, 50,4 Gy entsprechend, errechnete sich kumulativ eine Gesamtdosis am Hoden von 1,60 Gy (0,98-3,19 Gy). Schlussfolgerungen: Das maennliche Keimepithel reagiert auf Bestrahlung ausserordentlich sensibel im Sinne eines negativen Fraktionierungseffektes. Bei Gesamtdosen > 1,5 Gy, fraktioniert appliziert, gilt die Azoospermie als meist irreversibel. Die von uns ermittelte Gonadendosis fuehrt nach den Daten der Literatur sehr wahrscheinlich zu einer dauerhaften Sterilitaet. Wegen der geringen Patientenanzahl sind die Daten vorsichtig zu interpretieren, dennoch muss der Patient ueber die hohe Wahrscheinlichkeit einer bleibenden Infertilitaet aufgeklaert werden. Eine moegliche praetherapeutische Spermakryokonservierung sollte mit dem Patienten besprochen werden. (orig.)

    Some municipal and industrial sewage treatment plants comprise an aerobic and an anaerobic unit. However, discharge conditions may be such as to cause strong oxidants like hydrogen peroxide (H{sub 2}O{sub 2}) to enter the anaerobic unit. As measurements of the reduction-oxidation potential in an acidification stage showed, small concentrations of H{sub 2}O{sub 2}, already, may cause irreversible damage to the anaerobic bacterial strains living there. Adding activated sludge from the aerobic unit to such a system can prevent the damage. Probably, the enzyme catalase protects the anaerobic system against the oxydizing effect of hydrogen peroxide: this enzyme from aerobic bacteria and optionally aerobic bacteria causes the ecologically compatible decomposition of hydrogen peroxide into water and oxygen, which is substantially less reactive. Optionally aerobic bacteria, which are also added, protect the anaerobic system further by consuming this oxygen. (orig.) [Deutsch] Manche kommunalen und industriellen Klaeranlagen bestehen aus einer Aerobie und einer Anaerobie. Verschiedene Einleitungsbedingungen koennen aber dazu fuehren, dass in die Anaerobie starke Oxidationsmittel wie Wasserstoffperoxid (H{sub 2}O{sub 2}) gelangen. Messungen des Redoxpotentials in einer Versaeuerungsstufe zeigen, dass bereits geringe Konzentrationen an H{sub 2}O{sub 2} die dort lebenden anaeroben Bakterienkulturen irreversibel schaedigen. Wird aber einem solchen System Belebtschlamm aus der Aerobie zudosiert, so kann diese Schaedigung verhindert werden. Wahrscheinlich schuetzt das Enzym Katalase die Anaerobie vor der oxidierenden Wirkung des Wasserstoffperoxids. Dieses Enzym aus aeroben und fakultativ aeroben Bakterien zersetzt naemlich Wasserstoffperoxid oekologisch vertraeglich in Wasser und den bedeutend weniger reaktiven Sauerstoff. Zum Schutz der Anaerobie wird auch dieser Sauerstoff durch die zudosierten fakultativ aeroben Bakterien verbraucht. (orig.)

    2011-07-01

    Microbiologically influenced corrosion (MIC) is a widespread problem that is difficult to detect and assess because of its complex mechanism. This paper presents the involvement of microorganisms in MIC. Some of the mechanisms that cause MIC include hydrogen consumption, production of acids, anode-cathode formation and electron shuttling. A classic bio-corrosive microorganism in the oil and gas industry is sulphate-reducing prokaryotes (SRP). Methanogens also increase corrosion rates in metals. Some of the phylogenetic orders detected while studying SRP and methanogens are archaeoglobales, clostridiales, methanosarcinales and methanothermococcus. There were some implications, such as growth of SRP not being correlated with growth of methanogens; methanogens were included in MIC risk assessment. A few examples are used to display how microorganisms are involved in topside corrosion and microbial community in producing wells. From the study, it can be concluded that, MIC risk assessment includes system data and empirical knowledge of the distribution and number of microorganisms in the system.

    of the algae cells during the sorption experiment and a behavior analogue to initially heat killed cells. Differences in the contribution of functional groups to the uranium binding depending on the metabolic activity of the algal biomass were also shown by the difference spectra of the ATR-FTIR measurements calculated between uranium contaminated and untreated biomass. All together the spectroscopic investigations showed in case of Chlorella vulgaris a mixture of functional groups is responsible for the coordination of U(VI). The metabolic activity of the cells influences the binding of uranium under the given experimental conditions. Models of the structure of the formed U(VI)-algae complexes in dependence of the metabolic activity were created. For living algal cells, mainly carboxylic and organic phosphate groups are involved in the binding of uranium, whereas in dead algal biomass additionally inorganic phosphates are involved to some extend in the interaction of uranium with algal cells. The transferability of the obtained findings concerning the experiments in mineral medium to natural occurring mining related waters was verified exemplary with the surface water of ''Gessenwiese'' (former ''Gessenhalde'' at Ronneburg). The obtained results of this study contribute to the prediction of the migration behavior of uranium under environmental conditions, the radiological risk assessment of geogenic and anthropogenic appearing uranium and a reliable estimation of the accumulation of uranium in the food chain.

    .7 t of oxidized nitrogen, 66% resulting from cloud-to-ground lightning. One hour after the lightning activity had terminated, a total of 15 t is found in the anvil altitude. Extrapolated to a global LNO{sub x}-production rate, the results of the simulation would imply that LNO{sub x} is by far the most dominant NO{sub x}-source. However, the model thunderstorm case was unusual for the region. The comparison between the observed and modeled anvil NO{sub x}-profiles shows many similarities in structure and absolute values. This can help to estimate the uncertainties involved with extrapolating aircraft NO{sub x}-measurements to a NO{sub x}-production rate. As a conclusion, the MM5 thunderstorm simulation with a Lagrangian particle representation for LNO{sub x} is capable to reproduce significant microphysical and chemical observations, and can help to estimate the impact of lightning on the tropospheric NO{sub x} budget.

    Including public interest groups in the siting process for nuclear waste disposal facilities is of great importance. Controversial sitings often result in litigation, but involving public interest groups early in the process will lessen the change of this. They act as surrogates for the general public and should be considered as members of the team. It is important to remember though, that all public interest groups are different. In choosing public panels such as public advisory committees, members should not be chosen on the basis of some quota. Opposition groups should not be excluded. Also, it is important to put the right person in charge of the committee. The goal of public involvement is to identify the conflicts. This must be done during the decision process, because conflicts must be known before they can be eliminated. Regarding litigation, it is important to ease through and around legal battles. If the siting process has integrity and a good faith effort has been shown, the court should uphold the effort. In addition, it is important to be negotiable and to eliminate shortcuts

    Recent initiatives have promoted the participation of fathers in the early care of their children. To assess the results of a program to encourage parental involvement in childbirth. Parents of healthy term newborns were randomly allocated to participate either in the birth experience or control. The protocol included: to dry the skin, umbilical cord cutting off, weight, height, and finally give him/her to the mother for the skin-to-skin contact. Heart rate (HR), respiratory (RR) and temperature were evaluated one hour later.

  20. Effectiveness of citizen involvement

    Energy Technology Data Exchange (ETDEWEB)

    Robinson, L. [Prince William Sound Regional Citizen' s Advisory Council, Anchorage, AK (United States)

    2006-07-01

    This paper reviewed the rise of citizen involvement in industry that affects their community. Following the Exxon Valdez oil spill (EVOS) in 1989, the Oil Pollution Act of 1990 provided funding by industry for a citizens group to provide oversite of the Alyeska Pipeline Service Agency terminal and associated tankers. That role is currently filled by the Prince William Sound Regional Citizen's Advisory Council, a volunteer organization that represents communities that were affected by the EVOS. The history of the Prince William Sound Regional Citizen's Advisory Council was discussed along with its structure, funding and overview of projects and research into safer transportation of oil, better oil spill response capabilities and improved environmental protection practices. Some of the successes involving citizen input include the requirement that all tankers going into Prince William Sound be double hull by 2015; a world-class system of tugs escorting tankers in Prince William Sound; installation of an ice-detection radar on a small island near the site of the EVOS; a guidebook for communities affected by man-made disasters; identification of nearshore locations that should be the first to be protected in the case of another spill; and, the installation of a system to capture crude oil vapors when tankers take on cargo. Other projects underway include the study of invasive species that can be transported in the ballast water of tankers, efficacy of dispersants, soil contamination at the tanker loading site, emissions of hazardous air pollutants from ballast water treatment processes, and continual review of emergency response plans. In the 17 years since the formation of the Prince William Sound Regional Citizen's Advisory Council, it has been shown that communication and transparency are the keys to solving complacency, which is believed to have been a contributing factor to the EVOS. 3 refs.

    Abfallverbrennungsanlagen nachtraeglich um leistungsfaehige Rauchgasreinigungssysteme ergaenzt werden. Dies fuehrte zu einem erheblichen Anstieg der Kosten und Behandlungsgebuehren mit dem entsprechenden Druck zur optimierten Nutzung. Zusaetzliche Behandlungskapazitaeten werden benoetigt fuer heizwertreiche Abfaelle. Sie koennen zwar in konventionellen Abfallverbrennungsanlagen fuer Hausmuell behandelt werden, bedingen aber aufgrund des hoeheren Heizwertes eine Durchsatzreduzierung was die Kostensituation weiter negativ beeinflusst. Daher favorisieren aktuelle Konzepte die Behandlung heizwertreicher Abfaelle in spezifischen, dezentralen Anlagen. Die ueblicherweise kleinen Anlagen gehen einher mit hohen Nebenkosten der Errichtung. Zur Abschaetzung des Optimierungspotentials bestehender Abfallverbrennungsanlagen wurde deren Auslastungssituation untersucht. Bei umfangreichen Messkampagnen am MHKW Darmstadt konnte selbst bei 100%iger Auslastung der Verbrennungseinheit in der Rauchgasreinigungsanlage eine Luecke aufgezeigt werden, die durch eine entsprechend angepasste Vorschaltanlage aufgefuellt werden koennte. Eine solche Vorschaltanlage definiert zusammen mit der bestehenden Abfallverbrennungsanlage eine HYBRID-Abfallbehandlungsanlage. Die Bereitstellung eines Instrumentariums zur Unterstuetzung der Entscheidungsfindung bei der Konzeption solcher Anlagen ist Gegenstand dieser Arbeit. (orig.)

    Full Text Available Nine-hundred-eighty-nine patients with lymphoma were studied. Fifty-three cases (5.3% had lymphomatous craniocerebral infiltration. The principal factors of risk for this complication were: advanced stage of the lymphoma (III or IV, diffuse histiocytic, diffuse poorly differentiated lymphocytic, or mixed cellularity lymphoma histological type, bone marrow involvement, and previous systemic chemotherapy. Thirty-two per cent of the cases of meningeal lymphomatous infiltration were asymptomatic and represented autopsy findings. CT-scan was an useful test to detect brain focal parenchymatous infiltration, as opposed to meningeal infiltration. Mean survival time in patients with lymphomatous meningeal infiltration was 4.3 months, following the combined use of systemic chemotherapy, radiation therapy and intrathecal methotrexate. Two cases had primary cerebral lymphoma, although without associated immunodeficiency Twenty patients (2% had intracranial hemorrhage, in clear relationship with platelet alterations. Fifteen patients (1.5% had CNS infection, caused by common bacteriae or opportunistic agents. In 7 cases, the diagnosis was made at autopsy. Thirty-six autopsies were performed. In 8 cases (22%, pathologic findings such as, demyelination, microcalcificat ons, coagulative necrosis, or gliosis, suggested complications from treatment.

  5. Health injuries by noise; Gesundheitsgefahren durch Laerm

    Within the civilized world, noise is a common danger for health. There is not only the well known hearing loss by occupational noise, but there are also a lot of noise induced hearing losses by noise injuries in private life which are comparable to the occupational ones. The sources of these injuries within private life mostly are unknown and can be found in household goods as well as from listening to loud music. Also the danger from loud cracks mostly is underestimated, so as the cracks from children toys often reach more than 150 dB(Al). Alladay`s noise levels, e.g. in public trafic, also reach dangerous levels, and the sum of all these noise injuries results in a lesion of the cilias of the outer hair cells in the Corti`s organ. The resulting hearing loss is called `sociacusis` and increases the effect of physiological presbyacusis to an amount that results in the fact, that more than 10% of all adults in civilized countries have a severe, handicapping deafness. The immediate effect of noise in this regard is intensified by the effects of disturbing noise onto the psychovegetative and hormonal regulations by chronical stress. So people in civilized countries are going to become a society of hard hearing subjects, and deafness will become a common peoples` disease. (orig.) [Deutsch] Laerm ist in der zivilisierten Welt ein allgemeines Gesundheitsproblem. Es gibt nicht nur die berufliche Laermschwerhoerigkeit, die gut erforscht ist, sondern schaedlicher Laerm tritt sehr oft auch im Privatleben auf und verursacht Gehoerschaeden, die der beruflich bedingten Laermschwerhoerigkeit vergleichbar sind. Die Gehoergefaehrdung im Privatleben ist oft unbekannt und betrifft neben lauten Geraeten im Haushalt und dem Hoeren zu lauter Musik auch die oft in ihrer Gefaehrlichkeit unterschaetzten Knalle, die selbst bei Kinderspielzeug Spitzenwerte der Pegel von ueber 150 dB(Al) erreichen. Die allgemeine zivilisatorische Laermbelastung, z.B. im oeffentlichen Verkehr, die oft schaedigende Ausmasse erreicht, im Beurteilungspegel aber unter den Grenzwerten bleibt, bewirkt im Laufe der Jahre ebenfalls bleibende Schaeden an der Zilien der aeusseren Haarzellen des Corti-Organs, die eine ueber die physiologische Alterung hinausgehende `Soziakusis` bewirken. Schliesslich haben die staendigen Geraeusch- und Laermbelaestigungen und -stoerungen des Alltagslebens deutliche Effekte auf die neurovegetativen und hormonellen Regulationen des Organismus und verursachen somit mittelbar ueber Stressreaktionen ebenfalls Hoerstoerungen in Form von Hoerstuerzen und Tinnitus. Der alltaegliche Laerm, dem zu wenig Bedeutung zugemessen wird, droht Schwerhoerigkeit, von der mehr als 10% aller Erwachsenen betroffen sind, zur Volkskrankheit werden zu lassen. (orig.)

    Simulator training is a key component in achieving and preserving on the long term the necessary expertise of plant personnel also required by the authorities. In this way, it makes an important contribution to the safe operation of nuclear power plants. Simulators are a component in the training of operating personnel of nuclear power plants which allows nuclear power plant operators to be prepared in a focused and practice-oriented way for their activity in everyday plant operation and for possible accident simulation. The simulator center is supported by 5 nuclear power plant operators: the German E.ON Kernkraft GmbH, RWE Power AG, EnBW Kraftwerke AG, and Vattenfall Europe Nuclear Energy GmbH companies as well as the Netherlands N.V. Electriciteits-Produktiemaatschappij Zuid-Nederland. They established a joint enterprise in Essen which performs in one central place the duty of simulator training incumbent upon all nuclear power plants. (orig.)

    Full Text Available Virtual reality will gain a more and more important role in our everyday life. So it is very important to understand fully the impact and influence virtual reality will have on or view of the world. This article reveals that the interdependencies between the real space and the virtual space are much more subtle and profound then on first sight. Especially the value of several mathematical, physical and biological models and simulation methodologies will be reestimated by the use of virtual reality in the long term. As an example the article describes the historical chain from quaternions to quaoaring and how this may lead to a paradigm change in biology.

    Full Text Available Zusammenfassung In Alexander von Humboldts Tagebüchern seiner berühmten Forschungsreise durch Spanisch-Amerika finden sich Bemerkungen und Hinweise für künftige Leser seiner Reisedarstellungen zu Problemen der Verpflegung. Zumeist werden Engpässe und Missstände erwähnt sowie Fragen soziopolitischer Situation verdeutlicht. Sie beziehen sich auf Extrembedingungen in stadtfernen Gebieten und im Kontakt mit den indigenen Trägern und Helfern während der einzelnen Exkursionen. Die Darstellungen der alltäglichen Gegebenheiten sind zugleich eine interessante Quelle für Verhaltensmuster der verschiedenen Schichten der spanischkolonialen Gesellschaft wie der Forschungsreisenden, die mit den Schwierigkeiten umzugehen hatten, sich anzupassen verstanden oder ihre eigenen Verhaltensmuster entwickelt haben. Damit ermöglichen Humboldts Aufzeichnungen zugleich auch auf diesem Gebiet manchen Blick auf den seither erfolgten Kulturwandel. Resumen En los diarios del famoso viaje de estudios de Alejandro de Humboldt por la América española se encuentran observaciones y notas sobre problemas de aprovisionamiento, en favor de lectores futuros de sus relaciones de viaje. En la mayoría de los casos Humboldt menciona situaciones precarias o ilustra cuestiones de carácter sociopolítico. Frecuentemente, sus apuntes se refieren a condiciones extremas en regiones remotas y en contacto con los cargadores y ayudantes indígenas durante las diferentes excursiones. Las descripciones de los acontecimientos cotidianos al mismo tiempo son una fuente interesante sobre los modos de proceder de las diferentes capas de la sociedad colonial española así como de los viajeros científicos que tuvieron que enfrentar dificultades a las cuales había que adaptarse o desarrollar modelos propios de comportamiento. Por esto al mismo tiempo las noticias de Humboldt también en este asunto posibilitan más de una vez la atención al cambio cultural que se ha realizado hasta hoy

    Military fathers endure repeated separations from their children. In this qualitative study we describe military fathers' range of involvement with their children, paying special attention to the implications of deployment separation and reintegration. We discuss father involvement using three overlapping major domains of functioning: cognitive, affective, and behavioral. Additionally, we consider how types of father involvement differ vis-à-vis child age. Data were gathered via focus groups conducted with 71 fathers at 14 U.S. military installations. Descriptions of involvement were rich and varied. Involvement with children was a major concern for fathers, despite or perhaps because of the challenges of military careers. We discuss factors that help explain variations in involvement and offer insights about the conceptualization of father involvement for occupations requiring prolonged absences from home.

    2015-01-01

    Full Text Available Pseudogout is the acutest form of arthritis in the elderly. Although clinical manifestations vary widely, polyarticular involvement is typical mimicking osteoarthritis or rheumatoid arthritis. Monoarticular involvement is relatively rare and is generally provoked by another medical condition. There are reported cases of hip involvement by pseudogout in monoarticular form. However, all of the cases were presented as septic arthritis. In this report, we present a case of monoarticular hip involvement mimicking soft tissue abscess. We confirmed the pseudogout diagnosis after ultrasonographic evaluation of the involved hip joint and pathological and biochemical analysis of synovial fluid analysis. Diagnosis is important to avoid unnecessary medical and surgical treatment in cases of the bizarre involvement of hip in pseudogout.

    The investigations characterize aerosols and clouds over Garmisch-Partenkirchen by lidar remote sensing, and support the interpretation of measurements of the transfer of UV radiation. Extensive tests of calibration procedures were performed, and the lidar system was modified to meet the requirements. The focal point were measurements accompanying the CUVRA (Characteristics of the UV Radiation field in the Alps) campaign at IFU in March 1999. 767 lidar measurements in two wavelength channels were performed on 12 days during this campaign. Aerosol and cloud situations were characterized by determining lower and upper layer heights (time resolution down to 1 minute, height resolution down to 15 meters), multi layer situations from ground to the tropopause region (up to 5 aerosol and cloud layers), optical depths at 532 nm and 355 nm (range 0.01 to 3), wavelength dependences of the optical depth between 532 nm and 355 nm (range of wavelength exponent 0 to -2), and lidar ratios (extinction/backscatter) at 532 nm (range 20 to 38). (orig.) [German] Die Untersuchungen charakterisieren Aerosole und Wolken ueber Garmisch-Partenkirchen durch Lidar-Fernerkundung und dienen der Interpretation von Messungen des UV-Strahlungsflusses.

    To assess the contribution of road rage victimization and perpetration to collision involvement. The relationship between self-reported collision involvement and road rage victimization and perpetration was examined, based on telephone interviews with a representative sample of 4897 Ontario adult drivers interviewed between 2002 and 2004. Perpetrators and victims of both any road rage and serious road rage had a significantly higher risk of collision involvement than did those without road rage experience. This study provides epidemiological evidence that both victims and perpetrators of road rage experience increased collision risk. More detailed studies of the contribution of road rage to traffic crashes are needed.

    Directory of Open Access Journals (Sweden)

    Eva Heiskanen

    2007-01-01

    Full Text Available Involving users in the innovation process is a subject of much research, experimentation, and debate. Less attention has been given to the limits to user involvement that ensue from specific organizational characteristics. This article explores barriers to the utilization of users’ input in two small companies developing interactive digital applications. We contrast our findings to earlier research involving large companies to identify features of entrepreneurial sensemaking and action that influence the utilization of users’ input. We find that the small companies follow a distinct action rationality, leading to rapid implementation of some user inputs, and defensiveness toward others. Both sets of data also reveal common features that are often overlooked in the literature. We reconceptualize user involvement as a form of interaction between users and innovating companies that is facilitated and constrained by micro-sociological processes, on the one hand, and the nature of the competitive environment, on the other.

  1. Drug involvement in fatal overdoses

    Christopher J. Ruhm

    2017-12-01

    Full Text Available Death certificate data from the Multiple Cause of Death (MCOD files were analyzed to better understand the drug categories most responsible for the increase in fatal overdoses occurring between 1999 and 2014. Statistical adjustment methods were used to account for the understatement in reported drug involvement occurring because death certificates frequently do not specify which drugs were involved in the deaths. The frequency of combination drug use introduced additional uncertainty and so a distinction was made between any versus exclusive drug involvement. Many results were sensitive to the starting and ending years chosen for examination. Opioid analgesics played a major role in the increased drug deaths for analysis windows starting in 1999 but other drugs, particularly heroin, became more significant for recent time periods. Combination drug use was important for all time periods and needs to be accounted for when designing policies to slow or reverse the increase in overdose deaths.

    Tuberculosis in childhood is clinically challenging, but it is a preventable and treatable disease. Risk factors depend on age and immunity status. The most common form of pediatric tuberculosis is pulmonary disease, which comprises more than half of the cases. Other forms make up the extrapulmonary tuberculosis that involves infection of the lymph nodes, central nervous system, gastrointestinal system, hepatobiliary tree, and renal and musculoskeletal systems. Knowledge of the imaging characteristics of pediatric tuberculosis provides clues to diagnosis. This article aims to review the imaging characteristics of common sites for extrapulmonary tuberculous involvement in children.

    2004-10-01

    Vertebral osteomyelitis is most commonly due to pyogenic or granulomatous infection and typically results in the combined involvement of the intervertebral disc and adjacent vertebral bodies. Non-infective causes include the related conditions of chronic recurrent multifocal osteomyelitis (CRMO) and SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) syndrome. Occasionally, these conditions may present purely within the vertebral body, resulting in various combinations of vertebral marrow oedema and sclerosis, destructive lesions of the vertebral body and pathological vertebral collapse, thus mimicking neoplastic disease. This review illustrates the imaging features of vertebral osteomyelitis without disc involvement, with emphasis on magnetic resonance imaging (MRI) findings.

    Rasmussen encephalitis (RE) is a rare devastating disease of childhood causing progressive neurological deficits and intractable seizures, typically affecting one hemisphere. Characteristic MRI features include progressive unihemispheric focal cortical atrophy and grey- or white-matter high-signal changes and basal ganglion involvement, particularly of the caudate nucleus. To analyse the pattern of involvement of different brain structures in a series of patients with RE and to attempt clinical correlation. We reviewed the medical records and neuroimaging data of 12 patients diagnosed with RE satisfying the European Consensus Statement diagnostic criteria. The disease manifested as seizures in all patients and was refractory; epilepsia partialis continua was a notable feature (nine patients). Hemiparesis of varying grades was noted in all but one patient; none had extrapyramidal signs. Neuroimaging showed cortical involvement in the insular/periinsular regions in 11 patients. Caudate atrophy was noted in ten patients. Putaminal atrophy was seen in nine patients, six of whom had additional hyperintense signal changes. Our study highlights frequent putaminal atrophy and signal changes in RE, which suggests a more extensive basal ganglion involvement than emphasized previously. Recognition of putaminal changes may be a useful additional tool in the radiological diagnosis of RE. (orig.)

    2016-10-01

    Full Text Available Cutaneous Hodgkin’s lymphoma is a rare disease (0.5% to 3.4% which tends to be in the setting of an advanced disease and has a poor prognosis. Treatment of patients with cutaneous involvement of Hodgkin’s lymphoma is according to dissemination of disease (systemic or localized therapy. The majority of data in this context are based on individual case reports or literature reviews. We have reported a case of Hodgkin’s lymphoma that relapsed with isolated cutaneous involvement two years after completion of his first treatment. Our case had no response to systemic chemotherapy but obtained a complete remission to radiation therapy and had longterm disease-free survival. Radiotherapy might be considered a good salvage treatment in patients with cutaneous Hodgkin’s lymphoma with long-term disease-free survival.

    Lupus panniculitis is an unusual immunological disease that characteristically affects the subcutaneous fat and occurs in 2% of patients with systemic lupus erythematosus. We report a case of lupus panniculitis involving the breast, which represents a very uncommon location. Mammographically, it presented as a suspicious irregular mass involving the subcutaneous fat pad with skin thickening. High echogenicity constituted the most relevant sonographic finding. To the best of our knowledge, the magnetic resonance (MR) features have not been previously described. High signal intensity was found on both T1- and T2-weighted precontrast MR images. A dynamic contrast-enhanced study revealed a suspicious focal mass with irregular margins and rim enhancement, with a type 3 time-signal intensity curve. Differential diagnosis with carcinoma and fat necrosis and the value of core biopsy are discussed. (orig.)

    In the frame of this research project a simulation program has been developed in order to investigate suspension pressure build-up in crankshaft axial bearings taking into account mixed friction conditions. The investigated system is performing in a dynamic way taking into account the engine dynamics. Based upon the high engineering state of radial slide bearings, axial bearings as well as conical slide faces with any conical angle can be simulated in the same way. The solid body contact share in the system to be investigated is taken into account by the integral effect of the real microscopic surface structure on microhydrodynamics and contact pressure build-up. The influence of individual parameters, as e.g. macro-geometric bearing surface design can be investigated by means of simulation results. Wavy stopping faces and bearing surfaces with Rayleigh-steps are characterised by high hydrodynamic supporting pressure magnitudes in terms of macrogeometry. Elasto-hydrodynamic investigations at one stop collar and under engine-specific load on stop disks of a base bearing show the influence of structure elasticity and prove the necessity to consider them when the individual systems are analysed.

    Full Text Available The objectives of this paper are to discuss a rare cause of laryngeal multiple myeloma, to review unique pathologic findings associated with plasma cell neoplasms, to discuss epidemiology, differential diagnosis, and treatment options for plasma cell neoplasms of the larynx. Laryngeal multiple myeloma, also noted in the literature as “metastatic” multiple myeloma, presenting as a de novo laryngeal mass is extremely rare with few reported cases. Laryngeal involvement of extramedullary tumors is reported to be between 6% and 18% with the epiglottis, glottis, false vocal folds, aryepiglottic folds, and subglottis involved in decreasing the order of frequency. We present the case of a 58-year-old male with a history of IgA smoldering myeloma who presented to a tertiary care laryngological practice with a two-month history of dysphonia, which was found to be laryngeal involvement of multiple myeloma. We review the classification of and differentiation between different plasma cell neoplasms, disease workups, pathologic findings, and treatment options.

  19. Stakeholder involvement - a japanese perspective

    International Nuclear Information System (INIS)

    Kobayashi, S.

    2004-01-01

    Traditional societal and cultural background of Japanese in general indicates the intrinsic difficulty in involving the public as stakeholders in the process of any type of decision making in policy matters. It is characterized by the long-taught virtue of harmonization and obedience to others. In addition, characteristic system of Japanese traditional industrial society, such as lifetime employment, seniority-based wage system, and enterprise-based labour union, encourages the loyalty to the employer/company, but not to the public. The public or ordinary citizens would seldom come out as stakeholders and express their true feelings or real opinions, even though younger generation is notably getting out from such a trend. On the other hand, it is a common practice in Japanese society for any business or administrative transactions to try to obtain 'consensus' among relevant parties concerned (stakeholders) by negotiations behind the curtain prior to the formal discussion. In this sense, 'stakeholders involvement' is accepted and practised as a matter of course, but mostly for actions between parties of equivalently influential status levels or between 'directly relevant' parties such as those between the different government agencies, between regulators and industries. The concept of 'Involving the public in decision making as stakeholders' is not yet fully understood nor accepted in Japan both by regulators and by the public so far as the issue of radiation protection is concerned. These situations are explained with some examples. (author)

  20. Ethics in research involving prisoners.

    Science.gov (United States)

    Pont, Jörg

    2008-01-01

    Research involving prisoners repeatedly went astray during the last century, culminating in the cruel medical experiments inside the Nazi concentration camps that gave rise to the Nuremberg Code. However, prisoners continued to become victims of scientific exploitation by the rapidly evolving biomedical research industry. The common roots of these abuses were the flawed philosophy that the needs of the society outweigh the needs of the individual and the researchers' view that prisoners are cheap, easy to motivate and stable research subjects. Prisoners are vulnerable to exploitation and abuse by research because their freedom for consent can easily be undermined, and because of learning disabilities, illiteracy and language barriers prevailing within prisoner populations. Therefore, penal laws of some countries supported by a number of internationally agreed documents prohibit research involving prisoners completely. However, prisoners must also be regarded as vulnerable to the specific health problems in prisons, e.g. transmissible diseases, mental disorders and suicide - problems that need to be addressed by research involving prisoners. Additionally, the participation of prisoner patients in research they directly can benefit from should be provided. Hence, it must be a common objective to find the right balance between protection from exploitation and access to research beneficial to prisoners.

  1. DHA involvement in neurotransmission process

    2007-05-01

    Full Text Available The very high enrichment of the nervous system in the polyunsaturated fatty acids, arachidonic (AA, 20: 4n-6 and docosahexaenoic acids (DHA, 22: 6n-3, is dependant of the dietary availability of their respective precursors, linoleic (18: 2n-6 and_-linolenic acids (18: 3n-3. Inadequate amounts of DHA in brain membranes have been linked to a wide variety of abnormalities ranging from visual acuity and learning irregularities, to psychopathologies. However, the molecular mechanisms involved remain unknown. Several years ago, we hypothesized that a modification of DHA contents of neuronal membranes by dietary modulation could change the neurotransmission function and then underlie inappropriate behavioural response. We showed that, in parallel to a severe loss of brain DHA concomitant to a compensatory substitution by 22:5n-6, the dietary lack of α-linolenic acid during development induced important changes in the release of neurotransmitters (dopamine, serotonin, acetylcholine in cerebral areas specifically involved in learning, memory and reward processes. Data suggested alteration of presynaptic storage process and dysregulations of reciprocal functional interactions between monoaminergic and cholinergic pathways. Moreover, we showed that recovery of these neurochemical changes was possible when the deficient diet was switched to a diet balanced in n-3 and n-6 PUFA before weaning. The next step is to understand the mechanism involved. Particularly, we focus on the study of the metabolic cooperation between the endothelial cell, the astrocyte and the neuron which regulate synaptic transmission.These works could contribute to the understanding of the link between some neuropsychiatric disorders and the metabolism of n-3 PUFA, through their action on neurotransmission.

    Behcet's disease is a vasculitis of unknown origin that was traditionally defined by oral and genital ulcers and uveitis. We describe a case of a patient with a diagnosis of Behcet's syndrome who presented a palpable lesion in the right breast with inflammatory signs. X-ray findings posed a differential diagnosis between tumoral and inflammatory pathology. The pathological findings confirmed a small-vessel vasculitis. We found two reports of breast involvement by this disease in the literature. Our patient was studied by mammogram and sonogram which together with clinical history are important to prevent delay in diagnosis and unnecessary therapeutic procedures. (orig.)

    Glomuvenous malformation (GVM) is an inherited autosomal dominant trait. The lesions, which appear as bluish nodules or plaque-like cutaneous elevations, are usually tender and more firm than sporadic venous malformations. Conventionally, the lesions are thought to be limited to the cutaneous and subcutaneous tissue planes. The objective was to characterize the depth of involvement of GVM lesions. Magnetic resonance imaging (MRI) findings in GVM were retrospectively evaluated by two radiologists. The signal characteristics, tissue distribution, pattern of contrast enhancement of the lesions in GVM were documented. Thirty patients (19 female) aged 1-35 years (mean 18 years) were diagnosed with GVM based on clinical features (n = 20) and/or histopathological findings (n = 10). The lesions were present in the lower extremity (n = 15), upper extremity (n = 6), cervico-facial region (n = 6), pelvis (n = 2), and chest wall (n = 1). All patients had skin and subcutaneous lesions. Fifty percent of the patients (n = 15) demonstrated subfascial intramuscular (n = 15), intra-osseous (n = 1), and intra-articular involvement (n = 1). Contrary to the conventional belief that GVMs are generally limited to the skin and subcutaneous tissue, deep subfascial extension of the lesions is common. (orig.)

    Pulmonary involvement in secondary syphilis is considered a rare occurrence; however, the number of cases has increased in the 2000s. This is likely due to the increased use of computed tomography scans and molecular diagnostic testing. We report a case of an HIV-positive man with pleural chest pain and bilateral subpleural nodules on chest computed tomography. His rapid plasma reagin and Treponema pallidum hemagglutination tests were positive, and the specimen of one of the pulmonary nodules obtained by transthoracic biopsy was positive for the polA gene of Treponema pallidum. Since clinical manifestations of syphilis are highly variable, clinicians should bear in mind that pleural chest pain with bilateral subpleural nodules can be caused by pulmonary syphilis.

    A 66-year-old woman, who was diagnosed with iritis, visited our hospital due to general malaise. A blood analysis revealed hypercalcemia. Computed tomography revealed mediastinal and hilar lymph node hyperplasia. Moreover, 67 Gallium scintigraphy demonstrated strong accumulation in the lesions, suggesting sarcoidosis. A core needle biopsy (CNB) of the hypoechoic areas of the thyroid was performed because the patient refused to undergo a bronchoscopic examination. The scattering of slightly acidophilic epithelioid cell granulomas was observed in the pathological examination of the biopsy specimen. Based on this finding, the patient was diagnosed with sarcoidosis. Although sarcoidosis rarely involves the thyroid gland, in the present case, thyroid CNB was an alternative diagnostic method that allowed a pathological diagnosis to be obtained.

    Full Text Available Importance. Cutaneous and systemic plasmacytosis are rare conditions of unknown etiology with characteristic red-brown skin lesions and a mature polyclonal plasma cell infiltrate within the dermis. Perineural plasma cell infiltrates may be a histologic clue to the diagnosis of cutaneous plasmacytosis. Observations. Our patient had a five-year history of persistent reddish-brown plaques on the neck and trunk without systemic symptoms. Histologic examination showed dermal perivascular and perineural plasma cells with excess lambda light chain expression. Due to decreased quality of life caused by his skin lesions, he was placed on a chemotherapeutic regimen with bortezomib. Conclusions and Relevance. The patient was diagnosed with cutaneous plasmacytosis based on classic histopathology results with a recently characterized pattern of perineural involvement. Bortezomib therapy was initiated to manage his skin eruption, which has not been previously described as a treatment for this chronic condition.

    Full Text Available Rheumatoid Arthritis (RA is a widespread disease and its renal involvement, relatively common, is clinically significant because worsens course and mortality of the primary disease. There is still no agreement on the prevalence of renal disorders in RA: data analysis originates from different sources, as death certificates, autopsies, clinical and laboratory findings and kidney biopsies, each with its limitations. Histoimmunological studies on bioptical specimens of patients with RA and kidney damage, led to clarify prevalent pathologies. In order of frequency: glomerulonephritis and amyloidosis (60-65% and 20-30% respectively, followed by acute or chronic interstitial nephritis. Kidney injury during RA includes secondary renal amyloidosis, nephrotoxic effects of antirheumatic drugs and nephropathies as extra-articular manifestations (rheumatoid nephropathy. Amyloidosis affects survival, increases morbidity and is the main cause of end stage renal disease in patients with RA and nephropathy. Strong association between RA activity and amyloidosis needs the use of immunosuppressive and combined therapies, to prevent this complication and reduce risk of dialysis. Long-lasting and combined RA pharmacotherapy involves various renal side effects. In this review we describe NSAIDs and DMARDs (Disease-Modifying Antirheumatic Drugs nephrotoxicity, particularly by gold compounds, D-penicillamine, cyclosporine A and methotrexate. Rare cases of IgA glomerulonephritis during immunomodulating therapy with leflunomide and TNF blocking receptor (etanercept are reported; real clinical significance of this drug-related nephropathy will be established by development of RA treatment.

    Vascular involvement in tuberous sclerosis (TS) is rare. Central and peripheral aneurysms and large and medium size arterial stenotic-occlusive disease have been reported in patients with TS. We present here three pediatric patients with TS and severe vascular abnormalities, followed by a review of the literature. The three cases include a 14-month-old girl with polycystic kidneys and cerebral tubers who had a large asymptomatic abdominal aortic aneurysm, a 2-year-old boy with multiple features of TS who had hypertension and was found to have mid-aortic syndrome with bilateral renal artery stenosis, and an 18-year-old girl with abdominal pain and TS features who had greater than 70% celiac artery stenosis. In all cases, noninvasive vascular imaging modalities were utilized for either initial diagnosis, surveillance, or both. These cases highlight the collaborative roles of the pediatric nephrologist and cardiovascular imager in the diagnosis and management of the vascular complications in TS patients. Appropriate care can only be made through a high index of suspicion.

    2017-01-01

    Nail psoriasis is considered a significant psychological and social problem causing functional impairment in affected patients. Nail changes hamper their daily and occupational activities and contribute to a worse quality of life. Almost 50% of patients with psoriasis vulgaris and up to 80% of patients with psoriatic arthritis are afflicted with nail lesions. The important correlation between psoriatic arthritis and nail changes is well established - the presence of the latter is a strong predictor of the development of arthritis. There is a broad spectrum of nail dystrophies associated with psoriasis, ranging from the common pitting, subungual hyperkeratosis and loosening of the nail plate to less frequent discolouration and splinter haemorrhages. Some of these symptoms are also observed in other nail diseases, and further diagnostics should be performed. The assessment tools NAPSI (Nail Psoriasis Severity Index), mNAPSI (Modified Nail Psoriasis Severity Index), and PNSS (Psoriasis Nail Severity Score) are most commonly used to grade the severity of nail involvement in psoriasis and enable the evaluation of therapy effectiveness. The treatment of nail psoriasis is a major clinical challenge. It should be adjusted to the extent of dermal, articular and ungual lesions. Systemic therapies of psoriasis, especially biological agents, are most likely to be effective in treating nail psoriasis. However, as their use is limited in scope and safety, topical therapy remains a mainstay, and the combination of corticosteroids and vitamin D 3 analogues is considered to be most helpful.

    Expert opinions and court documents show that a sound knowledge of the medical examiner of the risks involved in the diagnostic methods applied will provide protection both for the patient and the medical examiner. Information of the patient being required by law, this book is intended to offer medical examiners a comprehensive source of information covering all imaging methods for diagnostics and therapy and the related risks, the data for the survey being drawn from the relevant literature. Particular attention has been paid to invasive methods such as angioplasty and diagnostic biopsy including ultrasonic monitoring, which have been developed recently. A great variety of established methods and examination techniques which soon will be replaced by new techniques such as sonography, computerized tomography and, probably, nuclear tomography but still are widely used, also form part of the survey. The various chapters are entitled: Information offered by risk statements; intravenous application of contrast media; arteriography; transcatheteral vascular occlusion; angioplasty; intracavitary, interstitial application of contrast media and lymphography; bronchoradiography; biopsy of organs in the cervical and thorax regions; biopsy of abdominal organs; hysterosalpingography; gastro-intestinal contrast radiography; court decisions referring to malpractice and the duty to inform patients on diagnostic radiographic methods; energy transfer to the human organism.

    This final report for the Swiss Federal Office of Energy (SFOE) reports on work done concerning the development of a new type of frequency converter for drive applications. The converter is free of the disadvantages incurred when using voltage converters, where it is difficult to reduce standby power consumption since much energy is stored in the intermediate circuit condensers. The new current converter completely provides the desired advantages (recuperation, standby). In addition, it is suited to industrial applications with costs that are comparable to or lower than the systems used today. The report discusses the technical solution chosen, its applications and the costs involved. Prototypes are described and the results of measurements made are discussed.

  20. Fluid involvement in normal faulting

    Science.gov (United States)

    Sibson, Richard H.

    2000-04-01

    Evidence of fluid interaction with normal faults comes from their varied role as flow barriers or conduits in hydrocarbon basins and as hosting structures for hydrothermal mineralisation, and from fault-rock assemblages in exhumed footwalls of steep active normal faults and metamorphic core complexes. These last suggest involvement of predominantly aqueous fluids over a broad depth range, with implications for fault shear resistance and the mechanics of normal fault reactivation. A general downwards progression in fault rock assemblages (high-level breccia-gouge (often clay-rich) → cataclasites → phyllonites → mylonite → mylonitic gneiss with the onset of greenschist phyllonites occurring near the base of the seismogenic crust) is inferred for normal fault zones developed in quartzo-feldspathic continental crust. Fluid inclusion studies in hydrothermal veining from some footwall assemblages suggest a transition from hydrostatic to suprahydrostatic fluid pressures over the depth range 3-5 km, with some evidence for near-lithostatic to hydrostatic pressure cycling towards the base of the seismogenic zone in the phyllonitic assemblages. Development of fault-fracture meshes through mixed-mode brittle failure in rock-masses with strong competence layering is promoted by low effective stress in the absence of thoroughgoing cohesionless faults that are favourably oriented for reactivation. Meshes may develop around normal faults in the near-surface under hydrostatic fluid pressures to depths determined by rock tensile strength, and at greater depths in overpressured portions of normal fault zones and at stress heterogeneities, especially dilational jogs. Overpressures localised within developing normal fault zones also determine the extent to which they may reutilise existing discontinuities (for example, low-angle thrust faults). Brittle failure mode plots demonstrate that reactivation of existing low-angle faults under vertical σ1 trajectories is only likely if

    In the present pilot study we established an ELISA based detection system which allows sensitive monitoring of stress induction as a result of heavy metal pollution. The system is based on the immunological detection of the stress induced hsp70 in larvae of Chironomidae. Using this system it is possible to detect environmental pollution by heavy metals far beyond lethal toxicity values. Since only very few animals are needed the system can also be used in field tests. For poluted isopodes as Oniscus asellus for example a single animal turned out be sufficient to monitor stress induction by Pb{sup +}. The established system ought to serve as basis for a more extended study in which different animals are collected from various polluted environments and tested with respect to already induced hsp synthesis. (orig.) [Deutsch] In der vorliegenden Pilotstudie konnte ein sensitives Nachweissystem fuer die Induktion des ubiquitaeren Stresssystem durch Schwermetalle auf der Basis der immunologischen Detektion von HSP70 etabliert werden. Dieses, auf ELISA Basis arbeitende Testverfahren ermoeglicht es Schwermetallbelastungen weit unterhalb der Toxizitaetsgrenze ueber die Induktion der HSP70 Synthese in Chironomidenlarven nachzuweisen. Die Tatsache, dass nur wenige Tiere fuer eine statistische Aussage benoetigt werden laesst eine Anwendungsmoeglichkeit auch auf Freilandtiere erwarten. So reicht fuer bleibelastete Freiland-Asseln ein einziges Tier zum immunologischen Belastungsnachweis aus. Damit sind die Grundlagen fuer die zweite Phase, die Freilandphase, in welcher sowohl Freilandtiere als auch Gewaesser- und Sedimentproben von verschiedenen Standorten in die Untersuchungen miteinbezogen werden sollen; geschaffen. Es koennen jetzt Tiere aus belasteten Gewaessern bezueglich bereits erfolgter Stressproteinproduktion aber auch auf eine Neuinduzierbarkeit nach zusaetzlicher Laborbelastung untersucht werden. Ebenso koennen Labortiere auf ihre Reaktion gegenueber belasteten

    Full Text Available [english] Background: Ever since the last amendment to the German Medical Licensing Act took effect in 2002, medical students may complete four months of the Practical Year (PY in general practices. Formative feedback between the teaching general practitioner (GP and the PY student is a key element in creating a learning environment. GPs involved in teaching therefore need further education in giving feedback.Methods: A 4-hour feedback training session for GPs involved in teaching which used standardized patients and students was developed and tested in a pilot study. In role plays, GPs experienced feedback situations. Using an evaluation questionnaire, changes in self-perceived feedback skills were assessed (familiarity of feedback rules, preparation for giving feedback to PY students, possibilities to improve communication skills in doctor–patient situations.Results: Sixteen GPs who were involved or interested in PY teaching participated in the feedback training program. Afterwards, participants said they felt more comfortable in giving formative feedback and more assured in their communication skills. The confidence in their own feedback improved, especially by taking the student’s part in the role plays. An exercise between a standardized patient and a standardized stubborn student was a challenge, but proved to be extremely useful.Conclusion: The opinions of the participating GPs to the feedback training underscore its importance. Therefore, we recommend integrating such a feedback training program into the education of GPs involved in teaching.[german] Hintergrund: Seit der letzten Novelle der Approbationsordnung 2002 besteht die Möglichkeit, ein Tertial des Praktischen Jahres (PJ in Hausarztpraxen zu absolvieren.

    Despite agreement on the value of father involvement in children's lives, research has been limited due to the exclusion of fathers in studies, questionable validity of mothers' reports on father involvement, and simple measures of fathering behavior. Our study extends previous research by comparing reports of father involvement using robust, multidimensional father involvement measures. Data from 113 fathers and 126 mothers reporting on 221 children were used to assess father involvement. Results indicate that fathers reported significantly higher levels of involvement than mothers reported. Findings from hierarchical linear models suggest that race/ethnicity and mothers' reports of positive relationship quality were associated with smaller discrepancies in reports of father involvement, whereas nonmarried partnerships, older children, father residence, and biological status predicted larger discrepancies. Our study demonstrates the importance of obtaining father involvement reports directly from fathers and why father involvement should be assessed as a multidimensional construct to examine fathering behavior.

    The research project analyses the influence of exceeded speeds on main urban roads in terms of environmental quality. In the analysis, aspects of emissions of harmful substances, noise, the quality of living and residential surrounding, urban separation effects as well as road safety aspects concerning pedestrians and cyclists were examined. Speed surveillance and accordant ticketing in case of violation are common in German cities. A survey carried out in several cities revealed that environmental aspects play hardly a role when considering control measures. Such measures are mainly viewed as 'traffic safety measures'. The most important result was that sanctioned monitoring (with fines) is indispensable for better compliance with the permissible maximum speed. Sanctions and their effect on speed behaviour were examined in the sample cities Rostock, Berlin and Dresden. In situations with a reasonably steady traffic flow speeds between 30 and 50 km/h were found to be most consistent with environmental protection objectives. Attaining this level requires a combination of conceptual planning measures and statutory regulatory measures, as well as the comprehensive involvement of all interested parties in the planning processes, the use of active and passive enforcement efforts, short-term interventions to modify streets or their cross-sections, and targetted public relations efforts. Within the study, an 'Analytical plan to evaluate complex environmental effects' (AKU) was developed. This plan serves as a tool for evaluation and decision making for certain measures and for the analysis of traffic effects on residents. In this plan, conclusions concerning various environmental aspects and the effect on residents are considered and assessed by a simplified approach. Furthermore, action priorities with a conceptual planning bias were derived. With regard to regulative judicial measures the study identified that speeding violations have to be monitored

    Respiratory involvement in systemic lupus erythematosus (SLE) is not as well known as the cutaneous, rheumatological and renal manifestations. It occurs frequently but the diagnosis may be difficult because of the heterogeneity of the anatomical and clinical presentations. A precise diagnosis is crucial as new immunosuppressive drugs have considerably improved the prognosis. The pathology involves genetic, endocrine, environmental, pharmacological and immunological factors with a cytotoxic reaction of auto antibodies against complement, a circulating immune complex reaction and a hyperactivity of B lymphocytes. Respiratory involvement in SLE can be classified in 5 groups based on the anatomy: pleural involvement, infiltrating pneumonia (lymphoid interstitial pneumonia, bronchiolitis obliterans with organizing pneumonia and acute lupus pneumonitis), airways involvement (upper airways, bronchi), vascular involvement (pulmonary hypertension, acute reversible hypoxaemia, alveolar haemorrhage, and antiphospholipid syndrome), muscular and diaphragmatic involvement (shrinking lung syndrome). Treatment is based, depending upon the type of involvement and its severity, on steroids which may be combined with immunosuppressants and plasmapheresis.

    Full Text Available [english] Background and aims: The final year of the undergraduate medical curriculum in Germany consists of three 16-week rotations including one hospital-based rotation in internal medicine. The final-year program is supposed to be oriented toward real-world practice and competency-based learning. A Clinical Education Ward (CEW was developed to promote contextual and self-directed learning among medical students during their final-year rotation in internal medicine. The goal of multisource evaluation is to analyze the implications of this model in terms of patient care, ward organization, and the learning progress of medical students. Prerequisites for a “learning organization” should be established. Methods: At the CEW, final-year medical students were acting as “doctors under supervision” and taking care of patients in a ward for internal medicine. Students were instructed and closely supervised by clinical tutors. All patients admitted to the CEW were surveyed using a questionnaire to assess the implications of student involvement in clinical care. Clinical staff members (physicians, nurses, therapists were asked about changes in terms of ward organization and interprofessional teamwork. Students assessed themselves at the beginning and at the end of the rotation in terms of clinical competencies, which were developed in cooperation with the students in preparation for the CEW.The project is part of the Integrated Studies of Anthroposophic Medicine program at the University of Witten/Herdecke (Germany, which aims to foster self-directed learning. Results: Fifty-six patients on the CEW were asked to complete a survey; 34 (60.7% responded. The majority (71% saw positive implications of student involvement in clinical care. Staff members (n = 28, return: 23 or 82% were in favor of the continued implementation of the CEW as a permanent institution.

    Stadtgebieten ist die Belastung der Oberflaechenabfluesse nicht allein von der Verkehrsdichte abhaengig. Dies gilt hoechstens ueber die Partikelbeladung hinsichtlich einiger Elemente. Das Fahrverhalten, z.B. haeufiges Anfahren und Bremsen, ist hier ebenso von Bedeutung. Weiterhin beeinflussen die Hintergrundbelastung, Abspuelungen von unbefestigten Flaechen sowie weitere Aktivitaeten (z.B. intensive Bautaetigkeit) die Belastung von Nebenstrassen. Im Verlauf der untersuchten Niederschlagsereignisse war nach ca. 6 mm Niederschlag die Auswaschung der bodennahen Luftschicht beendet. Nach einem gefallenen Niederschlag von jeweils 15 mm konnte bei zwei Ereignissen die nahezu vollstaendige Abspuelung der partikulaeren Fracht festgestellt werden. Rund 80% der Schwermetallbelastung (bei Cu nur ca. 50%) des Einzugsgebietes werden durch die Emissionen des Strassenverkehrs verursacht. Kupferdaecher emittieren rund 40% der Cu-Fracht. Die Schwermetallfracht der Dachabfluessen ist ueberwiegend in der fluessigen Phase enthalten (ausser Pb, Fe), dagegen ist die Fracht der Strassenabfluesse zu ueber 90% partikulaer gebunden.

    While it has been argued that religion influences the meaning of work, few studies have empirically examined how employees' religiosity and job attitudes relate to one another. Specifically, this study investigated the relations among three religious orientations (intrinsic, extrinsic-personal, and extrinsic-social) and job involvement for 100 employees of a rehabilitation hospital in the southern United States. The respondents completed the 1989 Intrinsic/Extrinsic-Revised Scale and the 6-item version of the 1965 Job Involvement Scale. Correlation indicated a negative association between Intrinsic Religiosity and Job Involvement (r=-.26, pJob Involvement (r=.23, pJob Involvement for Protestants (B=.32, pJob Involvement for non-Protestants (B=-.35, pJob involvement for either group. These results suggest that employees' religiosity may influence work values in different ways for Protestant and non-Protestant workers.

    Images of three animal cadaver hips, 8 dissected patient femoral heads and 18 hip joints of human corpses, all either with arthrosis stage I-III or artificial cartilage defects, were compared with their corresponding anatomic sections. Additional histomorphologic examinations of the arthrotic cartilages were conducted, and MR-Imaging of 20 healthy and 21 arthrotic patient hips was performed using a specific traction method. Using a T{sub 1}-weighted 3-dimensional gradient-echo sequence and a traction of the hip joint, it was possible due to the low-signal imaging of the joint space to separate in vivo the high-signal femoral head cartilage from the high-signal acetabular cartilage. In horizontal position of the phase-encoding parameter, minimisation of the chemical-shift artifact, mainly in the ventro-lateral areas, was accomplished. MRI measurements of the articular cartilage widths showed significant correlations (p < 0.001) with the corresponding anatomic sections. At the same time the T{sub 1} 3-dimensional gradient-echo sequence of the lateral femoral head with r = 0.94 showed the lowest deviations of the measurements. It was possible with MR-Imaging to distinguish four cartilage qualities.

    MRI was performed in 13 patients with osteonecrosis involving the knee. We analyzed the MR images, distribution of the lesions, involvement of other sites, and chronological changes. The lesions tended to be multiple, and the marginal double line sign was thought mainly due to chemical shift misregistration. The lesions often involved medial and lateral femoral condyle. In the light of chronological change, the lesions became smaller or migrated toward the epiphyseal end. It was suggested that MRI was useful for the evaluation of osteonecrosis involving the knee.

A retrospective analysis was made of thoracic CT studies made at the time of diagnosis of 259 patients with lymphoma. Mediastinal pulmonary, pleural, pericardial and chest wall involvement was assessed by CT. Of 259 patients (129 men y 130 women), 56 had Hodgkin's disease (HD) and 203 had non-Hodgkin lymphoma (NHL). Forty-two percent (42.5%, 110/259) of the patients had chest involvement on CT: 33 of 56 patients with HD (58.9%) and 77 of 203 patients with NHL (37.9%). All the patients with thoracic HD) and 71.4% of patients with thoracic NHL, had mediastinal lymph node involvement. of the patients with thoracic involvement 12.1% (4/33) of the patient with HD and 23.3% (18/77) of the patients with NHL had pulmonary involvement. Thoracic involvement on CT was more frequent in HD. Mediastinal lymph node involvement was the most common finding fundamentally in HD. Pulmonary disease always occurred in the presence of mediastinal lymph node involvement in HD but could occur as an isolated finding in NHL. (Author) 24 refs

    2010-10-01

    Respiratory involvement in systemic lupus erythematosus (SLE) is not as well-known as the cutaneous, rheumatological and renal manifestations. It occurs frequently but the diagnosis may be difficult because of the heterogeneity of the anatomical and clinical presentations. A precise diagnosis is crucial as new immunosuppressive drugs have considerably improved the prognosis. The pathology involves genetic, endocrine, environmental, pharmacological and immunological factors with a cytotoxic reaction of auto-antibodies against complement, a circulating immune complex reaction and a hyperactivity of B lymphocytes. Respiratory involvement in SLE can be classified in five groups based on the anatomy: pleural involvement, infiltrating pneumonia (lymphoid interstitial pneumonia, bronchiolitis obliterans with organizing pneumonia and acute lupus pneumonitis), airways involvement (upper airways, bronchi), vascular involvement (pulmonary hypertension, acute reversible hypoxaemia, alveolar haemorrhage, and antiphospholipid syndrome), muscular and diaphragmatic involvement (shrinking lung syndrome).Treatment is based, depending upon the type of involvement and its severity, on steroids which may be combined with immunosuppressants and plasmapherisis.

  2. Hartbearbeitungen durch Drehen, Bohren und Fräsen

    Science.gov (United States)

    Barfels, Lutz

    Lange Zeit dachte man bei der spanabhebenden Bearbeitung gehärteter Stähle nur an eine Schleifbearbeitung. Die Entwicklung der hoch- bzw. superharten Schneidstoffe CBN (Kubisches Bornitrid, siehe auch Abschn. 20.3.3.16 "Schneidstoffe" und Abschn. 23.2 "Keramische Werkstoffe") und PKB (Polykristallines kubisches Bornitrid) führte seit den 1980er Jahren zur Zerspanung dieser Werkstoffe mit geometrisch bestimmten Schneiden. Seit dieser Zeit wird die Bearbeitung gehärteter Werkstoffe mit einer Härte über 50 HRC als Hartbearbeitung oder Hartzerspanung bezeichnet. Sie wird sowohl beim Drehen als auch beim Bohren und Fräsen eingesetzt. Die größte Bedeutung hat hier das Hartdrehen. Während das Hartdrehen bis vor einigen Jahren beinah ausschließlich in der Einzel- und Kleinserienfertigung eingesetzt wurde, wird es heute zunehmend auch für Großserien und in der Massenfertigung angewendet. In der Regel bestehen Vorteile für den Einsatz des Hartdrehens dann, wenn in einer Aufspannung mehrere unterschiedliche Geometrie- oder Formelemente (konisch, zylindrisch, …) bearbeitet werden müssen. Bei der Bearbeitung in einer Aufspannung sind sehr gute Lagegenauigkeiten der Funktionsflächen erreichbar. Weiterhin sind Hartdrehprozesse für die Innen- und die Außenkonturbearbeitung von großer Bedeutung.

    The efficiency of energy is one of several key performance parameters, when it comes to the questions how innovative and economical a plant operates compared to its competitors. However, in order to evaluate energy saving potentials in the industry, we need transparency first: A clear picture of the energy consumption based on products and processes. This transparency can be accomplished through business intelligence (BI). This term encompasses analytical processes and tools that can help to transform enterprise data and information into applied knowledge. In this article, we focus on transparency of the energy consumption through a targeted analysis by making use of business intelligence.

    2013-11-01

    Full Text Available Alltagsmobilität – die Mobilität in der näheren Wohnumgebung – gilt in der aktuellen Mobilitätsforschung als ein wesentliches Fundament gesellschaftlicher Teilhabe. Zahlreiche Studien verweisen darauf, dass sie mit zunehmendem Alter sinkt, was dementsprechend mit einem Verlust an gesellschaftlicher Integration und sinkender Lebensqualität assoziiert wird. Dennoch existieren bislang keine Erkenntnisse darüber, wie dieser Prozess auf der Subjektebene konkret gestaltet wird, wie Veränderungen vor dem Hintergrund welcher (räumlichen Wahrnehmungen und Überzeugungen von den Individuen initiiert werden. Hier setzt die dem Beitrag zugrunde liegende Untersuchung an: Das Ziel ist es, auf der Basis einer qualitativ orientierten Untersuchung herauszuarbeiten, wie Veränderungen der Mobilität im Kontext der subjektiven Konstruktionsleistungen und Handlungen der Älteren in einer gegenstandsorientierten Theorie gefasst und erklärt werden können. In einem zweiten Schritt werden prospektiv Thesen darüber entwickelt, in welcher Weise der Einsatz eines technischen Hilfsmittels – eines "Mobilitätsassistenten", der im Rahmen eines vom BMBF (Bundesministerium für Bildung und Forschung geförderten Projekts entwickelt wird – auf die Wahrnehmungen und Überzeugungen der Älteren Einfluss nehmen und darauf aufbauend deren Mobilität fördern könnte.

  8. Neurological Involvement in Behcet’s Disease

    Directory of Open Access Journals (Sweden)

    Gülşen Akman-Demir

    2009-12-01

    Full Text Available One of the most dreaded organ involvement in Behcet’s disease is neurological involvement. The majority of the cases present with parenchymal CNS involvement characterized as a brainstem meningoencephalitis; a rarer presentation is dural sinus thrombosis. Both situations very rarely occur in the same patient. Since parenchymal neurological involvement in Behcet’s disease is associated with severe sequelae or mortality, it is a poor prognostic organ involvement. In contrast, dural sinus thrombosis in Behcet’s disease has a much better prognosis as compared to the parenchymal involvement, as well as dural sinus thromboses due to other etiologies. There are no randomized controlled treatment trials carried out in neuro-Behcet disease. Mostly accepted approach is to give high dose intravenous steroids at the atack, with a very slow tapering of steroid dose, and adding a long term immunosuppresant. One of the most critical points in neuro-Behcet treatment is not to stop steroids prematurely, and abruptly. It is notable that with the present treatment options, prognosis of neurological involvement in Behcet’s disease is not as grave as it was in the previous years.

  9. Gastro-intestinal involvement in systemic sclerosis

    2017-01-01

    Full Text Available The gastrointestinal (GI tract can be involved in up to 90% of patients with systemic sclerosis (SSc and is the leading cause of morbidity and third most common cause of mortality in these patients. The GI involvement can occur in the absence of cutaneous manifestations in 10% of patients. Vasculopathy, cellular and humoral immunity, and diffuse fibrosis are the principal pathogenetic mechanisms in SSc and begin with autoantibody-mediated neuronal damage followed by muscular damage and fibrosis. This leads to progressive dysmotility of the entire GI tract from mouth to anus and is responsible for the clinical manifestations including gastroesophageal reflux disease and dysphagia due to esophageal involvement, gastroparesis, small intestinal bacterial overgrowth and chronic intestinal pseudo-obstruction, and constipation due to colonic and fecal incontinence due to anorectal involvement. The clinical features resulting from the involvement of these organs often overlap and multiple areas may be involved simultaneously. The treatment remains mostly symptomatic because effective disease-modifying therapies are lacking. These patients are at a risk of malnutrition and nutritional screening, and thus rehabilitation is very important. Refractory cases require nutritional support in the form of enteral nutrition and/or home parenteral nutrition. Future research is needed in the pathogenesis, development of biomarkers for early identification of GI involvement at the asymptomatic stage, and targeted disease-modifying therapies, which can alter/halt the disease progression.

    Sarcoidosis is a highly variable, systemic granulomatous disease of hitherto unknown aetiology. The GenPhenReSa (Genotype-Phenotype Relationship in Sarcoidosis) project represents a European multicentre study to investigate the influence of genotype on disease phenotypes in sarcoidosis.The baseline phenotype module of GenPhenReSa comprised 2163 Caucasian patients with sarcoidosis who were phenotyped at 31 study centres according to a standardised protocol.From this module, we found that patients with acute onset were mainly female, young and of Scadding type I or II. Female patients showed a significantly higher frequency of eye and skin involvement, and complained more of fatigue. Based on multidimensional correspondence analysis and subsequent cluster analysis, patients could be clearly stratified into five distinct, yet undescribed, subgroups according to predominant organ involvement: 1) abdominal organ involvement, 2) ocular-cardiac-cutaneous-central nervous system disease involvement, 3) musculoskeletal-cutaneous involvement, 4) pulmonary and intrathoracic lymph node involvement, and 5) extrapulmonary involvement.These five new clinical phenotypes will be useful to recruit homogenous cohorts in future biomedical studies.

    The issue of parental involvement in an adolescent's decision to abort a pregnancy is complex and controversial. Consequently, the impact of legislation to mandate parental involvement is reviewed. Although the costs of such legislation are high, there are at least three important clinical benefits. First, a legal mandate will require many adolescents who would not otherwise involve their parents in this decision process to seek their counsel and emotional support. Second, parent's responsibility for the actions of their adolescent children is acknowledged within the legal system. Third, family unity may be promoted by allowing parents and adolescents an opportunity to deal more openly with the causes and implications of the pregnancy.

    eines zukünftigen „guten Arztes“ zu entwickeln und zu validieren. Daher beschränkt sich das Auswahlverfahren in Hamburg auf das pragmatische Ziel die Studienabbrecherzahl zu reduzieren, damit möglichst viele Studienanfänger durch gute Lehre zu „guten Ärzten“ ausgebildet werden. Methodik: Zu diesem Zweck wurde der HAM-Nat (Hamburger Auswahlverfahren für Medizinische Studiengänge - Naturwissenschaftsteil mit 52 Multiple-choice Fragen auf Schulniveau über naturwissenschaftliche Kenntnisse und ihre Anwendung entwickelt, zunächst an 6 Schulen in 3 Bundesländern erprobt und dann mit 333 Studienanfängern im Oktober 2006 durchgeführt. Das Testergebnis und die Abiturnote wurden mit dem Studienerfolg in den ersten beiden Semestern korreliert. Als Studienerfolgsparameter wurde die Anzahl der bestandenen Leistungsnachweise verwendet. Ergebnisse: Das HAM-Nat-Ergebnis korreliert nach dem 2. Semester höher mit dem Studienerfolg als die Abiturnote, von der es relativ unabhängig ist. Insbesonders zeigt die Simulation eines Auswahlverfahrens unter Berücksichtigung von HAM-Nat-Ergebnis und Abiturnote eine deutliche Reduktion der Zahl der Studienabbrecher im Vergleich zur jetzigen Auswahl nur nach Abiturnote. Weitere abgefragte mögliche Studienauswahlparameter wie belegte naturwissenschaftliche Kurse oder eine abgeschlossene Berufsausbildung korrelieren nicht mit besserem Studienerfolg. Schlussfolgerung: Der HAM-Nat ist ein wertvolles zusätzliches Auswahlverfahren für Studienbewerber in der Medizin. Aufgrund dieser Ergebnisse hat die Medizinische Fakultät Hamburg beschlossen, den HAM-Nat für die Studienbewerberauswahl zum Wintersemester 2008/2009 einzuführen.

    This report concerning Swedish nuclear waste management has been produced as part of a cross national research project: CARL - A Social Science Research Project into the Effects of Stakeholder involvement on Decision-Making in Radioactive Waste Management. Besides Sweden, the participating countries are Belgium, Canada, Finland, Slovenia and United Kingdom. A social science research team, working for three years, is in the first phase conducting research in their own countries in order to produce 6 country reports. During the next years the focus will shift to comparisons of stakeholder involvement practices in the participating countries. The report addresses current practices of Swedish nuclear waste management and their historical development. The main focus is on past, current and emerging patterns of stakeholder involvement in the siting of a deep repository for the final disposal of Sweden's spent nuclear fuel. The general questions attended to in the report are: Who are the main stakeholders, and how have they emerged and gained recognition as such? What are the issues currently subject to stakeholder involvement and how have these been decided upon? How is stakeholder involvement organized locally and nationally and how has this changed over time? How has stakeholder involvement gained acceptance as an activity of value in the siting of major waste facilities? The report have attempted to show the development of stakeholder involvement in the siting of a final repository for Sweden's spent nuclear fuel as resembling something other than a straightforward linear process of improvement and refinement. Stakeholder involvement has developed, over the past 15 years or so, into something more like a patchwork of different shapes and forms. Some of the forces that may well contribute to the further elaboration of the patchwork of stakeholder involvement have been pointed out, contingently modifying once more its overall colour and orientation.

    2014-06-01

    Full Text Available Disasters, both natural and man-made, cause major damage and loss of life. Because of this, governments around the world are looking at building resilience to ensure communities can recover quickly and have minimal impact from a disaster. Part of building resilience is to plan for disaster management and recovery. Literature reveals that construction contractors can play a critical role within this process as they have control of resource supply chains and key knowledge and skills they are well suited to assist in disaster planning. However, as literature also reveals there is currently little involvement of construction contractors in the disaster planning process. This gap between what should be done and what is currently done is investigated. Representatives from industry bodies are interviewed to determine their understanding of the industry’s involvement in disaster planning and what capacity the industry might have to be involved. The interviewee’s responses agree with current literature that there is currently little or no involvement with disaster planning however there is interest in being involved with disaster management planning if there was a forum for this to occur. Based on the responses the researcher has proposed a model to engage construction contractors within state government disaster management planning.

    Of 114 patients with Hodgkin's disease reviewed, 13 (11%) had bone involvement. The typical osseous lesion in Hodgkin's desease is a secondary manifestation in the axial skeleton. The lesions are mainly lytic; there is no relation between the site of the affection and the character of the lesion. Of 261 patients with non-Hodgkin lymphoma, 19 (7,3%) had bone involvement. Non-Hodgkin lymphoma very rarely affects the bone primarily; these lesions are lytic. Involvement of the appendicular skeleton is reported to be typical; this cannot be confirmed by our study. Most secondary osseous lesions in non-Hodgkin lymphoma are found in the cranium, the spine and the sternum; this pattern of distribution as well as the mainly lytic appearance can be considered typical.

    CONTEXT Prescribing errors involving medication dose formulations have been reported to occur frequently in hospitals. No systematic evaluations of the characteristics of errors related to medication dosage formulation have been performed. OBJECTIVE To quantify the characteristics, frequency, and potential adverse patient effects of prescribing errors involving medication dosage forms . DESIGN Evaluation of all detected medication prescribing errors involving or related to medication dosage forms in a 631-bed tertiary care teaching hospital. MAIN OUTCOME MEASURES Type, frequency, and potential for adverse effects of prescribing errors involving or related to medication dosage forms. RESULTS A total of 1,115 clinically significant prescribing errors involving medication dosage forms were detected during the 60-month study period. The annual number of detected errors increased throughout the study period. Detailed analysis of the 402 errors detected during the last 16 months of the study demonstrated the most common errors to be: failure to specify controlled release formulation (total of 280 cases; 69.7%) both when prescribing using the brand name (148 cases; 36.8%) and when prescribing using the generic name (132 cases; 32.8%); and prescribing controlled delivery formulations to be administered per tube (48 cases; 11.9%). The potential for adverse patient outcome was rated as potentially “fatal or severe” in 3 cases (0.7%), and “serious” in 49 cases (12.2%). Errors most commonly involved cardiovascular agents (208 cases; 51.7%). CONCLUSIONS Hospitalized patients are at risk for adverse outcomes due to prescribing errors related to inappropriate use of medication dosage forms. This information should be considered in the development of strategies to prevent adverse patient outcomes resulting from such errors. PMID:12213138

  19. Justification of novel practices involving radiation exposure

    Webb, G. [Radiation Protection Consul tant, Brighton (United Kingdom); Boal, T.; Mason, C.; Wrixon, T. [International Atomic Energy Agency, Vienna (Austria)

    2006-07-01

    The concept of 'justification' of practices has been one of the three basic principles of radiation protection for many decades. The principle is simple in essence - that any practice involving radiation exposure should do more good than harm. There is no doubt that the many uses of radiation in the medical field and in industry generally satisfy this principle, yielding benefits that could not be achieved using other techniques; examples include CT scanning and industrial radiography. However, even in the early period after the introduction of the justification principle, there were practices for which the decision on justification was not clear and for which different decisions were made by the authorities in different countries. Many of these involved consumer products such as luminous clocks and watches, telephone dials, smoke detectors, lightning preventers and gas mantles. In most cases, these practices were relatively small scale and did not involve large exposures of either individual workers or members of the public. Decisions on justification were therefore often made by the regulator without extensive national debate. Over recent years, several practices have been proposed and undertaken that involve exposure to radiation for purposes that were generally not envisaged when the current system of radiation protection was created. Some of these practices were reviewed during a recent symposium held in Dublin, Ireland and involve, for example, the x-raying of people for theft detection purposes, for detection of weapons or contraband, for the prediction of physical development of young athletes or dancers, for age determination, for insurance purposes and in cases of suspected child abuse. It is particularly in the context of such novel practices that the need has emerged for clearer international guidance on the application of the justification principle. This paper reviews recent activities of the IAEA with respect to these issues, including the

    Behcet's disease is a multisystem disease that involves the central nervous system up to half of cases. Presentation with neurologic symptoms occurs in 5 % of cases and cerebral venous thrombosis is one of its major manifestations. A feature not previously reported is progressive meningeal thickening with involvement of both optic nerves. We report a patient with cerebral venous thrombosis, meningeal thickening and contrast enhancement on MRI. This patient had two other unusual features: positive antineutrophil cytoplasmic antibodies and later development of central diabetes insipidus. (orig.)

    Full Text Available The creative industry is a fast developing sector of economy in many countries. Growing competition in this area has led many companies to implement strategy of users' involvement in product development in order to deliver products that are more aligned with customers’ needs. On the other hand, the attempt to align the customers’ expectations with artistic creativity may create tensions. Therefore, the aim of the research is to examine the methods of users’ involvement in product development and real impact of the users on project design. The obtained findings are based on two-year qualitative research project conducted in game development companies.

    Chest CT scans of 70 patients with malignant lymphoma were reviewed to evaluate the thoracic manifestation of malignant lymphoma. Sixteen patients had Hodgkin's disease and 54 patients had non-Hodgkin's lymphoma. The thoracic involvement of malignant lymphoma was observed i 47 patients (67.1%) and 11 of these patients had Hodgkin's disease, and 36 had non-Hodgkin's lymphoma. The most common finding was mediastinal lymphadenopathy and the most frequently involved sites were anterior mediastinal and paratracheal lymph nodes. Pulmonary parenchymal involvement was seen in 11 patients (15.7%), and CT scan showed thickening of bronchovascular bundle, parenchymal consolidation and nodules. Pleural effusion was seen in 18 patients (25.7%), however, without any evidence of parietal pleural thickening in all cases. Involvement of chest wall and breast was seen in two patient (2.9%). The data obtained through the current study showed no differences from those of previous reports, except the fact that there was no CT evidence of pleural thickening in patients who had pleural effusion

    2015-09-01

    To summarize the incidence and spectrum of spinal cord-related complications in patients of tuberculous meningitis. Reports from multiple countries were included. An extensive review of the literature, published in English, was carried out using Scopus, PubMed and Google Scholar databases. Tuberculous meningitis frequently affects the spinal cord and nerve roots. Initial evidence of spinal cord involvement came from post-mortem examination. Subsequent advancement in neuroimaging like conventional lumbar myelography, computed tomographic myelography and gadolinium-enhanced magnetic resonance-myelography have contributed immensely. Spinal involvement manifests in several forms, like tuberculous radiculomyelitis, spinal tuberculoma, myelitis, syringomyelia, vertebral tuberculosis and very rarely spinal tuberculous abscess. Frequently, tuberculous spinal arachnoiditis develops paradoxically. Infrequently, spinal cord involvement may even be asymptomatic. Spinal cord and spinal nerve involvement is demonstrated by diffuse enhancement of cord parenchyma, nerve roots and meninges on contrast-enhanced magnetic resonance imaging. High cerebrospinal fluid protein content is often a risk factor for arachnoiditis. The most important differential diagnosis of tuberculous arachnoiditis is meningeal carcinomatosis. Anti-tuberculosis therapy is the main stay of treatment for tuberculous meningitis. Higher doses of corticosteroids have been found effective. Surgery should be considered only when pathological confirmation is needed or there is significant spinal cord compression. The outcome in these patients has been unpredictable. Some reports observed excellent recovery and some reported unfavorable outcomes after surgical decompression and debridement. Tuberculous meningitis is frequently associated with disabling spinal cord and radicular complications. Available treatment options are far from satisfactory.

    The aim of our study was to evaluate radiologic findings of the tuberculosis involving breast. We evaluated the radiologic features of 17 patients (18 lesions) with tuberculous disease involving the breast. The radiologic examinations, including mammography (16 patients), ultrasonography (12 patients), and Gd-DTPA-enhanced dynamic MRI (6 patients), were analyzed. Mammographic findings included mass (12 of 17 lesions), calcification (3 of 17 lesions), asymmetric density with spiculated margin (5 of 17 lesions), and axillary lymph node enlargement (8 of 17 lesions). On ultrasonography, a smooth bordered mass (7 of 13 lesions) with thin boundary (7 of 13 lesions) and heterogeneous, intermediate internal echoes (9 of 13 lesions) were most commonly demonstrated. On Gd-DTPA-enhanced dynamic MRI, 3 lesions showed significant enhancement at the first minute after injection (3 of 7 lesions). The maximun enhancing amount was greater than 500 normalized units, and the enhancing pattern was smooth or irregular ring appearance. Breast involvement with tuberculosis is rare but should be considered in the differential diagnosis of a woman living in an endemic area or when extramammary foci of tuberculosis are present. A multimodality imaging approach with clinical evaluation will help to establish the diagnosis of tuberculosis involving breast. (orig.) (orig.) With 3 figs., 3 tabs., 28 refs.

  13. Stakeholder Involvement in Swedish Nuclear Waste Management

    International Nuclear Information System (INIS)

    Elam, Mark; Sundqvist, Goeran

    2006-01-01

    The focus in this paper is on past, current and emerging patterns of stakeholder involvement in the siting of a deep repository for final disposal of Sweden's spent nuclear fuel. In particular, we concentrate on how the two municipalities of Oskarshamn and Oesthammar have acted as engaged stakeholders, and have gained recognition as such, in the siting process. In general: How has stakeholder involvement gained acceptance as an activity of value in the siting of major waste facilities? What are the issues currently subject to stakeholder involvement and how have these been decided upon? An effect of the history of nuclear activity in Oskarshamn and Oesthammar is that stakeholder involvement over a final repository can be divided into social and technical issues. Both municipalities have out of tradition, as part of their social acceptance of a new repository, been prepared to surrender extended involvement in key safety issues. They have been prepared to do this because they also see themselves being able to delegate these safety issues to the government authorities SSI and SKI. These two authorities have been acceptable to the two municipalities as their legitimate 'technological guardians'. As physical geology re-enters the siting process for a deep repository, Oskarshamn appear more prepared to break with tradition than Oesthammar. Oskarshamn are currently demanding transparency from SKB in relation to the exact technical and geological criteria they will use to choose between them and Oesthammar as a repository site. In contrast to Oesthammar, Oskarshamn are preparing with the expected help of SKI and SSI to dispute their geology and its relation to nuclear safety with SKB if they consider it necessary. If Oskarshamn act to draw safety issues in relation to alternative methods and sitings into the EIA process where might this lead? As environmental groups now enter the process (three groups were granted funding in the first round - 2005) the character of site

    2011-01-01

    We construct the spin formalism in order to deal in a direct and natural way with processes involving transversity which are now of increasing popularity. The helicity formalism which is more appropriate for collision processes of definite helicity has been so far used also to manage processes with transversity, but at the price of computing numerous helicity amplitudes generally involving unnecessary kinematical variables.In a second step we work out the correspondence between both formalisms and retrieve in another way all results of the helicity formalism but in simpler forms.We then compute certain processes for comparison.A special process:the quark dipole magnetic moment is shown to be exclusively treated within the spin formalism as it is directly related to the transverse spin of the quark inside the baryon.

    2015-01-01

    Lupus nephritis (LN), the renal involvement in systemic lupus erythematosus, is currently diagnosed by histopathology obtained by percutaneous renal biopsy and is associated with increased morbidity and mortality in both adults and children. LN is more prevalent and severe in children, requiring aggressive and prolonged immunosuppression. The consequences of the diagnosis and its treatment have devastating long-term effects on the growth, well-being and quality of life of affected children. The paucity of reliable clinical indicators of the presence and severity of renal involvement have contributed to a halt in the reduction of progression to end-stage renal disease in recent years. Here, we discuss the recent development of biomarkers in the management of LN and their role as therapeutic targets. PMID:26079958

    2017-08-01

    Endometriosis-the ectopic implantation of endometrial-like tissue-affects 10% of adolescent females and adults. Bladder involvement, causing dysuria and hematuria, occurs in a very small number of endometriosis patients. The patient presented at age 12 years with dysuria and pelvic pain. Laparoscopy revealed stage I endometriosis. Postoperatively, she reported persistent dysuria and passage of tissue in her urine. Cystoscopy showed diffuse erythema; urine cytology revealed glandular and spindle cells suggestive of endometriosis. She was transitioned from oral contraceptives to an intranasal gonadotropin-releasing hormone agonist, with symptom resolution. Intravesicular endometriosis coinciding with stage I disease supports a mechanism of endometriosis dissemination other than direct bladder infiltration. Patients with endometriosis who complain of urinary symptoms warrant assessment, because intravesicular bladder involvement cannot be excluded using pelviscopy.

    1994-08-01

    Environmental surveillance at the Hanford Site began during the mid-1940s following the construction and start-up of the nation's first plutonium production reactor. Over the past approximately 45 years, surveillance operations on and off the Site have continued, with virtually all sampling being conducted by Hanford Site workers. Recently, the US Department of Energy Richland Operations Office directed that public involvement in Hanford environmental surveillance operations be initiated. Accordingly, three special radiological air monitoring stations were constructed offsite, near hanford's perimeter. Each station is managed and operated by two local school teaches. These three stations are the beginning of a community-operated environmental surveillance program that will ultimately involve the public in most surveillance operations around the Site. The program was designed to stimulate interest in Hanford environmental surveillance operations, and to help the public better understand surveillance results. The program has also been used to enhance educational opportunities at local schools

    Distinct functional pathways for processing words and numbers have been hypothesized from the observation of dissociated impairments of these categories in brain-damaged patients. We aimed to identify the cortical areas involved in Arabic number reading process in patients operated on for various brain lesions. Direct cortical electrostimulation was prospectively used in 60 brain mappings. We used object naming and two reading tasks: alphabetic script (sentences and number words) and Arabic number reading. Cortical areas involved in Arabic number reading were identified according to location, type of interference, and distinctness from areas associated with other language tasks. Arabic number reading was sustained by small cortical areas, often extremely well localized (area (Brodmann area 45), the anterior part of the dominant supramarginal gyrus (Brodmann area 40; p area (Brodmann area 37; p areas.

    1993-02-01

    Involving citizens, interest groups, and regulators in environmental restoration and waste management programs is a challenge for government agencies and the organizations that support them. To be effective, such involvement activities must identify all individuals and groups who have a stake in the cleanup. Their participation must be early, substantive, and meaningful. Stockholders must be able to see how their input was considered and used, and feel that a good- faith effort was made to reconcile conflicting objectives. The Integrated Demonstration for Cleanup of Volatile Organic Compounds at Arid Sites (VOC-Arid ID) is a Department of Energy Office of Technology Development project located at Hanford. Along with technical evaluation of innovative cleanup technologies, the program is conducting an institutional assessment of regulatory and public acceptance of new technologies. Through a series of interviews and workshops, and use of a computerized information management tool, stakeholders are having a voice in the evaluation. Public and regulatory reaction has been positive

    2016-01-01

    Volunteerism and community involvement have been demonstrated to offer benefits both to communities and to volunteers themselves. However, not every method to encourage these behaviors is equally effective in producing committed volunteers. Drawing on relevant theoretical and empirical literatures, we identify features of efforts that are likely to produce intrinsically motivated other-oriented volunteers and those that may produce extrinsically motivated self-oriented volunteers. In particular, we explore ways to socialize young people to help and ways to build a sense of community focused on particular issues. We also examine requirements for community service and other approaches that highlight self-oriented benefits that volunteers may obtain. Finally, we return to a focus on the importance of intrinsic motivation for promoting sustained involvement in volunteers, even as we acknowledge that volunteers who come with extrinsic or self-oriented reasons can still offer much to communities and can be satisfied when their activities match their motivations.

    2012-01-01

    Yeast cells undergo programed cell death (PCD) with characteristic markers associated with apoptosis in mammalian cells including chromatin breakage, nuclear fragmentation, reactive oxygen species generation, and metacaspase activation. Though significant research has focused on mitochondrial involvement in this phenomenon, more recent work with both Saccharomyces cerevisiae and Schizosaccharomyces pombe has also implicated the endoplasmic reticulum (ER) in yeast PCD. This minireview provides an overview of ER stress-associated cell death (ER-SAD) in yeast. It begins with a description of ER structure and function in yeast before moving to a discussion of ER-SAD in both mammalian and yeast cells. Three examples of yeast cell death associated with the ER will be highlighted here including inositol starvation, lipid toxicity, and the inhibition of N-glycosylation. It closes by suggesting ways to further examine the involvement of the ER in yeast cell death.

    2003-01-01

    Background: The association of Behcet's disease and ankylosing spondylitis is still a matter of debate. Objective: As the presence of sacroiliac joint involvement is an essential criterion in diagnosis of ankylosing spondylitis . We decided to determined the prevalence of sacroiliac joint involvement in Behcet's disease and compare it with that of a control group. Patients and Methods: We randomly selected two groups of 199 Behcet's disease patients and 168 non- Behcet's disease cases (the controls). All cases were over 20 years of ages. Standard anteroposterior radiographs of the sacroiliac joint were obtained and interpreted by two rheumatologists and a radiologists blinded to the diagnosis. To determined the severity of the condition, the following 5-point scale was employed: Normal (O), pseudo-widening (1), sclerosis (2), erosion (3), and bony fusion (4). The eliminate any doubt, only grades 3 and 4 were considered as sacroiliitis. Both group were separately evaluated for age (≤ 30, and ≥ 30), and gender. Results were compared using Chi square test. Results: The groups were matched for age and sex: There were 98 (49.2%) females in Behcet's disease vs. 91 (54.2%) in the control group (p=O.35). The mean ±SD age was 35±8.3 years in Behcet's disease and 35 ±10 in control group (p=1). The sacroiliac joint was involved in 9 (4.6%) patients in Behcet's disease and 7 (4.2%) patients in control group (p=O.93). Comparisons between the results of the unisexual cohorts revealed to significance either (p=O.68 for males, and p=O.64 for females). The age subdivisions (under- and over-30) again showed no significant difference (p=O.96 and p=O.69 for under- and over -30 patients, respectively). Conclusion: The presence of radiographic signs of sacroiliac joint involvement is not mandatory for the diagnosis of ankylosing spondylitis

    Cardiac myxomas are the most common type of primary cardiac tumors. They mainly affect the interatrial septum and exceptionally the heart valves. Surgical excision remains the only therapeutic alternative. We here report the case of a 69-year old patient with no significant pathological history suffering from NYHA class II-III dyspnea associated with lipothymia. Transthoracic echocardiography showed a tight calcified aortic narrowing with aortic valve gradient of 58 mmHg. A sessile mass of 15mm diameter inserted into the posterolateral leaflet, without stenosis or mitral regurgitation evoking an atypical localization of myxomaor or fibroelastoma was detected at the level of the mitral valve. The examination was supplemented by ETO which confirmed the diagnosis of a mass involving the posterolateral leaflet. The patient underwent surgery via median sternotomy, under conventional extracorporeal circulation. Left atriotomy allowed to objectify a sessile mass of 15mm of diameter involving the auricular wall of the friable and easily cleavable posterolateral leaflet. Cauterization of the implant base via electric scalpel was then performed without any additional gesture on the posterolateral leaflet. Anatomopathologic analysis of the surgical specimen confirmed the diagnosis of myxoma. The patient also underwent aortic valve replacement with mechanical prosthesis. The postoperative course was uneventful. The patient was discharged on postoperative day 8. Cardiac myxoma involving the mitral leaflet is very rare. Surgical procedure attempting to resect the widest possible surgical margins remains the only therapeutic option to avoid the risk of recurrence.

    Breast cancer is the most frequent cancer of women in western countries. There are one million new cases per year in the world which represents 22% of all female cancers, and more than 370.000 deaths due to breast cancer per year (14% of cancer mortality). More than half of breast cancers are associated with axillary nodal involvement. Post-operative radiation therapy (XRT) is a crucial part of locoregional treatment in axillary nodal involvement breast cancer owing to a 15-years risk reduction of locoregional recurrence of 70% and to a 5.4% risk reduction of specific mortality. In 3D-conformal irradiation in such breast cancers, target volumes are chest wall when mastectomy was performed or breast and boost of tumor bed in case of breast conservative surgery, and supra-clavicular and/or axillary and/or internal mammary node areas. The main organs at risk are ipsilateral lung, heart and brachial plexus. The aim of this article is to describe epidemiologic, radio anatomic and prognostic features of axillary nodal involvement breast cancer and to propose guidelines for 3D-conformal treatment planning in locally advanced breast cancers. This review is illustrated by a case report. (authors)

  18. Kinases Involved in Both Autophagy and Mitosis

    Full Text Available Both mitosis and autophagy are highly regulated dynamic cellular processes and involve various phosphorylation events catalysed by kinases, which play vital roles in almost all physiological and pathological conditions. Mitosis is a key event during the cell cycle, in which the cell divides into two daughter cells. Autophagy is a process in which the cell digests its own cellular contents. Although autophagy regulation has mainly been studied in asynchronous cells, increasing evidence indicates that autophagy is in fact tightly regulated in mitosis. Here in this review, we will discuss kinases that were originally identified to be involved in only one of either mitosis or autophagy, but were later found to participate in both processes, such as CDKs (cyclin-dependent kinases, Aurora kinases, PLK-1 (polo-like kinase 1, BUB1 (budding uninhibited by benzimidazoles 1, MAPKs (mitogen-activated protein kinases, mTORC1 (mechanistic target of rapamycin complex 1, AMPK (AMP-activated protein kinase, PI3K (phosphoinositide-3 kinase and protein kinase B (AKT. By focusing on kinases involved in both autophagy and mitosis, we will get a more comprehensive understanding about the reciprocal regulation between the two key cellular events, which will also shed light on their related therapeutic investigations.

    A preliminary investigation on ''Public involvment in the Danish energy policy. The nuclear power issue'' was carried out as part of the project on ''Public involvment in decision-making related to science and technology'' performed by the Directorate for Science, Technology and Industry of the OECD in Paris. The historical development of Danish energy policy is briefly described. An account is given of the nuclear controversy, and the development of public opinion is outlined. The public debate has been very widespread and intense, by far the most comprehensive debate since that concerning the European Communities. Assuming that the development of public opinion reflects the relative success or failure of the contending parties, the opponents of nuclear energy seem to have done best. Opinion polls showed some marked deviations among the electorate according to different variables. The most striking were those observed in relation to sex, age, education, and political preferences. One chapter treats the attitude of public authorities to extended public involvment, and special accounts are given of the Energy Information Committee, and the Energy Council. Finally the prime movers of the nuclear debate are dealt with, in particular the Organization for Information on Nuclear Energy OOA, which opposes nuclear power. (B.P.)

    Studies of school leadership suggest that visiting classrooms, emphasizing achievement and training, and supporting teachers are important indicators of the effectiveness of school principals. The utility of a behavior-analytic program to support the enhancement of these behaviors in 2 school principals and the impact of their involvement upon teachers' and students' performances in three classes were examined in two experiments, one at an elementary school and another at a secondary school. Treatment conditions consisted of helping the principal or teacher to schedule his or her time and to use goal setting, feedback, and praise. A withdrawal design (Experiment 1) and a multiple baseline across classrooms (Experiment 2) showed that the principal's and teacher's rates of praise, feedback, and goal setting increased during the intervention, and were associated with improvements in the academic performance of the students. In the future, school psychologists might analyze the impact of involving themselves in supporting the principal's involvement in improving students' and teachers' performances or in playing a similar leadership role themselves.

    Full Text Available Background/Aim. Systemic connective tissue diseases (SCTD are chronic inflammatory autoimmune disorders of unknown cause that can involve different organs and systems. Their course and prognosis are different. All of them can, more or less, involve the respiratory system. The aim of this study was to find out the frequency of respiratory symptoms, lung function disorders, radiography and high-resolution computerized tomography (HRCT abnormalities, and their correlation with the duration of the disease and the applied treatment. Methods. In 47 non-randomized consecutive patients standard chest radiography, HRCT, and lung function tests were done. Results. Hypoxemia was present in nine of the patients with respiratory symptoms (20%. In all of them chest radiography was normal. In five of these patients lung fibrosis was established using HRCT. Half of all the patients with SCTD had symptoms of lung involvement. Lung function tests disorders of various degrees were found in 40% of the patients. The outcome and the degree of lung function disorders were neither in correlation with the duration of SCTD nor with therapy used (p > 0.05 Spearmans Ro. Conclusion. Pulmonary fibrosis occurs in about 10% of the patients with SCTD, and possibly not due to the applied treatment regimens. Hypoxemia could be a sing of existing pulmonary fibrosis in the absence of disorders on standard chest radiography.

    Full Text Available Rheumatoid arthritis (RA is a systemic autoimmune rheumatic disease of unknown etiology, characterized by chronic erosive arthritis and extraarticular manifestations. Pulmonary involvement is one of the common extraarticular manifestations of RA and may show itself as bronchial tree lesions, rheumatoid nodules, Caplan's syndrome, and lesions in the pleura or pulmonary interstitium (interstitial lung involvement (ILI. High-resolution computed tomography allows the diagnosis of ILI in RA in nearly 70% of cases although the incidence of ILI may be lower (4 to 30% depending on diagnostic methods and patient selection criteria. There are several histopathological types of ILI, the differential diagnosis of which can be troublesome. Usual interstitial pneumonia (UIP and nonspecific interstitial pneumonia are major types of RA-associated ILI. UIP-pattern ILI has a more severe course than ILI with other histological patterns. The clinical presentation of ILI may be complicated by the likely toxic effect of a number of disease-modifying antirheumatic drugs (DMARDs used to treat RA, such as methotrexate and leflunomide, and biological agents (BAs, tumor necrosis factor-α (TNF-α inhibitors. The pathogenesis of pulmonary involvement in RA and the role of synthetic DMARDs and BAs in the development of ILI call for further investigations.An extraarticular manifestation, such as ILI, affects the choice of treatment policy in patients with RA.The relevance of a study of ILI is beyond question. The paper discusses the state-of-the-art of investigations in this area.

    Objectives Evidence suggests that gang involvement is associated with adverse health outcomes among high-risk youth. However, few studies have investigated the prevalence and correlates of gang affiliation among this population, particularly in Canada. We examined the relationship between self-reported gang involvement and early childhood traumatic experiences, social factors, and other behaviors in a study of drug-using, street-involved youth. Study Design Cross-Sectional Study Methods Data were derived from the At-Risk Youth Study (ARYS), a prospective study of street-involved youth in Vancouver, Canada. Between June 2009 and May 2011, participants were asked questions ascertaining lifetime gang involvement and gang affiliation in one’s social network. We examined the gender-specific correlates of gang involvement using stratified log-binomial regression analyses. Results Among 435 eligible participants, 94 (21.6%) reported gang involvement and 206 (47.4%) reported having friends in a gang. In gender-stratified models, males involved in gangs were more likely to be of Aboriginal ancestry (prevalence ratio [PR] = 1.63, 95% confidence interval [CI]: 1.09 – 2.44), have grown up in government care (PR = 2.03, 95%CI: 1.32 – 3.12), dealt drugs (PR = 2.52, 95%CI: 1.66 – 3.85), and been incarcerated (PR = 1.40, 95%CI: 1.29 – 2.80). Women involved in gangs were more likely to have reported a history of childhood sexual abuse (PR = 3.08, 95%CI: 1.15 – 8.27). Conclusions These results suggest that a variety of adverse experiences in early life are associated with an increased risk of gang affiliation among street-involved youth. Primary prevention strategies aiming to avert gang initiation among high-risk youth should seek to address childhood abuse and other traumatic experiences commonly experienced by this population.

    2004-12-01

    The publication of countless reports documenting the dismal state of science education in the 1980s, and the Third International Mathematics and Science Study (TIMMS) report (1996) called for a wider involvement of the scientific community in K-12 education and outreach. Improving science education will not happen without the collaboration of educators and scientists working in a coordinated manner and it requires a long-term, continuous effort. To contribute effectively to K-12 education all scientists should refer to the National Science Education Standards, a set of policies that guide the development of curriculum and assessment. Ocean scientists can also specifically refer to the COSEE recommendations (www.cosee.org) that led to the creation of seven regional Centers for Ocean Sciences Education Excellence. Scientists can get involved in K-12 education in a multitude of ways. They should select projects that will accommodate time away from their research and teaching obligations, their talent, and their interest but also contribute to the education reform. A few examples of effective involvement are: 1) collaborating with colleagues in a school of education that can lead to better education of all students and future teachers, 2) acting as a resource for a national program or a local science fair, 3) serving on the advisory board of a program that develops educational material, 4) speaking out at professional meetings about the value of scientists' involvement in education, 5) speaking enthusiastically about the teaching profession. Improving science education in addition to research can seem a large, overwhelming task for scientists. As a result, focusing on projects that will fit the scientist's needs as well as benefit the science reform is of prime importance. It takes an enormous amount of work and financial and personnel resources to start a new program with measurable impact on students. So, finding the right opportunity is a priority, and stepping

    Abstract Pituitary dysfunction is a rare manifestation of granulomatosis with polyangiitis (GPA) (Wegener). The main aim of this multicenter retrospective study was to describe the characteristics and outcomes of pituitary manifestations in patients with GPA included in the French Vasculitis Study Group database. Among the 819 GPA patients included in the database, 9 (1.1%) had pituitary involvement. The median age at diagnosis of GPA and pituitary involvement was 46 and 50.8 years, respectively. Pituitary involvement was present at onset of GPA in 1 case and occurred later in 8 patients after a median follow up of 58.5 months. When pituitary dysfunction occurred, 8 patients had active disease at other sites including ENT (n = 6), eye (n = 4), or central nervous system (n = 3) involvement. The most common hormonal dysfunctions were diabetes insipidus (n = 7) and hypogonadism (n = 7). Magnetic resonance imaging was abnormal in 7 patients. The most common lesions were an enlargement of the pituitary gland, thickening of the pituitary stalk, and loss of posterior hypersignal on T1-weighed images. All patients were treated with corticosteroid therapy and 8 patients received immunosuppressive agents for the pituitary involvement, including cyclophosphamide (n = 3), rituximab (n = 2), and methotrexate (n = 3). After a median follow-up of 9.2 years, GPA was in complete remission in 7 patients, but 8 patients were still under hormone replacement therapy. Among the 5 patients who had a subsequent MRI, 2 had complete resolution of pituitary lesions.By combining our study and the literature review, the frequency of hypogonadism and diabetes insipidus, among the patients with pituitary dysfunction, can be estimated at 78% and 71% respectively. Despite a high rate of systemic disease remission on maintenance therapy, 86% of the patients had persistent pituitary dysfunction. The patients who recovered from pituitary dysfunction had all been

    Full Text Available Objective: To study bladder involvement in systemic lupus erythematosus patients through clinical and laboratorial evaluation, ultrasonography, radiological and endoscopic examination. Methods: Thirty-nine patients, either outpatients or inpatients at the Department of Rheumatology of Hospital das Clínicas da Faculdade de Medicina from Universidade de São Paulo were evaluated as to clinical and laboratorial data. All patients were submitted to ultrasonographic evaluation of the upper urinary tract, radiological and endoscopic examinations of the middle and lower urinary tracts. Rresults: Mean age of patients varied between 13 and 62 years (median = 29 years. Thirty-six were females and three were males. The disease varied from 6 months to 22 years (median three years and one month. Clinical and laboratory activity of the disease was present in 30 patients. Twenty-two patients had the diagnosis of lupus established for three years or more. Twenty-five patients were asymptomatic and all had received corticosteroids for treatment at least once. Twenty-three received antimalarial drugs; ten received cytostatics, and seven patients received non-steroid anti-inflammatory drugs. Upper urinary tract ultrasonography was normal in all cases but one with staghorn calculus associated with neurogenic bladder secondary to neurological involvement by the disease. Vesicoureteral reflux was observed in two cases. Other two patients had significant post-voiding residual urine, both with neurogenic bladder secondary to nervous system involvement by lupus. The average bladder maximum capacity in an awaken patient was 342 mL, and was decreased in 18.9% of cases. This subgroup of patients presented a greater frequency of urinary symptoms and greater use of cytostatic drugs (Z > Z5%. A pathognomonic cystoscopic pattern of bladder involvement in systemic lupus erythematosus could not be established. Cystoscopic aspects similar to those seen in the initial or minor

    Kawasaki disease (KD) is an acute systemic vasculitis affecting medium-sized arteries, particularly the coronary arteries. Classic diagnosis is based in prolonged fever and different clinical features, including acute arthritis. Our objective is to determine the prevalence of arthritis at the moment of the diagnosis, the response to intravenous immunoglobulin infusion and the relation with cardiac findings. Retrospective study through review of medical records of 42 patients with KD from 1988 to 2013. Demographic, clinical, laboratory variables and treatment were reviewed. Male sex was predominant (57%). Fever (100%), exanthema (92,9%), conjunctivitis (78,6%), oropharingeal changes (76,2%), cervical lymphadenopathy (71,4%), edema (52,4%) and peripheral desquamation (46,3%) were reported. Eight patients presented ecocardiography alterations (ectasia and aneurism). Acute articular involvement was reported in 7 (16%) patients, including oligoarticular (57%), monoarticular (29%) and polyarticular (14%) patterns. All patients had elevation of acute phase reactants with neutrophilia (57%) and hypoalbuminemia (71,5%), but showed a good therapeutic response to intravenous immunoglobulin, without sequelaes. Sixteen patients had incomplete KD nine males, with 100% of fever exanthema (75%), conjunctivitis (56%) and 50% of cervical lymphadenopathy. Whereas oropharingeal changes and edemas was described in 44% and 25% of them. Four patients with incomplete KD had coronary artery abnormalities. Acute arthritis was an uncommon finding (16%) and resulted in no sequelae. Maybe the treatment with intravenous immunoglobulin and aspirin prevents the development of articular abnormalities and then leading to a decrease in its follow-up requierement by reumathologist. The cardiovascular sequelae, mainly incomplete KD, remains determining its prognosis. The presence of articular involvement seems not to have influence over cardiac involvement.

    On February 9, 1978 at 8:20 p.m., the duty officer for the Illinois Radiological Assistance Team was notified that a shipment containing uranium and plutonium was involved in an accident near Gibson City, Illinois on Route 54. It was reported that a pig containing an unknown amount of uranium and plutonium was involved. The Illinois District 6A State Police were called to the scene and secured the area. The duty officer in the meantime learned after numerous telephone calls, approximately 1 hour after the first notice was received, that the pig actually was a 48,000 pound cask containing 6 spent fuel rods and the tractor-trailer had split apart and was blocking one lane of the highway. The shipment had departed from Dresden Nuclear Power Station, Morris, Illinois, enroute to Babcox and Wilcox in Lynchburg, Virginia. Initial reports indicated the vehicle had split apart. Actually, the semi-trailer bed had buckled beneath the cask due to apparent excess stress. The cask remained entirely intact and was not damaged, but the state highway was closed to traffic. The State Radiological Assistance Team was dispatched and arrived on the scene at 12:45 a.m. Immediate radiation monitoring revealed a reading of 4 milliroentgen per hour at 10 feet from the cask. No contamination existed nor was anyone exposed to radiation unnecessarily. The cask was transferred to a Tri-State semi-trailer vehicle the following morning at approximately 6:30 a.m. At 9:30 a.m., February 10, the new vehicle was again enroute to its destination. This incident demonstrated typical occurrences involving transportation radiation accident: misinformation and/or lack of information on the initial response notification, inaccuracies of radiation monitorings at the scene of the accident, inconsistencies concerning the occurrences of the accident and unfamiliar terminology utilized by personnel first on the scene, i.e., pig, cask, vehicle split apart, etc

  9. Functional brain networks involved in reality monitoring.

    Source monitoring refers to the recollection of variables that specify the context and conditions in which a memory episode was encoded. This process involves using the qualitative and quantitative features of a memory trace to distinguish its source. One specific class of source monitoring is reality monitoring, which involves distinguishing internally generated from externally generated information, that is, memories of imagined events from real events. The purpose of the present study was to identify functional brain networks that underlie reality monitoring, using an alternative type of source monitoring as a control condition. On the basis of previous studies on self-referential thinking, it was expected that a medial prefrontal cortex (mPFC) based network would be more active during reality monitoring than the control condition, due to the requirement to focus on a comparison of internal (self) and external (other) source information. Two functional brain networks emerged from this analysis, one reflecting increasing task-related activity, and one reflecting decreasing task-related activity. The second network was mPFC based, and was characterized by task-related deactivations in areas resembling the default-mode network; namely, the mPFC, middle temporal gyri, lateral parietal regions, and the precuneus, and these deactivations were diminished during reality monitoring relative to source monitoring, resulting in higher activity during reality monitoring. This result supports previous research suggesting that self-referential thinking involves the mPFC, but extends this to a network-level interpretation of reality monitoring.

  10. Optimisation: how to develop stake holder involvement

    International Nuclear Information System (INIS)

    Weiss, W.

    2003-01-01

    The Precautionary Principle is an internationally recognised approach for dealing with risk situations characterised by uncertainties and potential irreversible damages. Since the late fifties, ICRP has adopted this prudent attitude because of the lack of scientific evidence concerning the existence of a threshold at low doses for stochastic effects. The 'linear, no-threshold' model and the 'optimisation of protection' principle have been developed as a pragmatic response for the management of the risk. The progress in epidemiology and radiobiology over the last decades have affirmed the initial assumption and the optimisation remains the appropriate response for the application of the precautionary principle in the context of radiological protection. The basic objective of optimisation is, for any source within the system of radiological protection, to maintain the level of exposure as low as reasonably achievable, taking into account social and economical factors. Methods tools and procedures have been developed over the last two decades to put into practice the optimisation principle with a central role given to the cost-benefit analysis as a means to determine the optimised level of protection. However, with the advancement in the implementation of the principle more emphasis was progressively given to good practice, as well as on the importance of controlling individual levels of exposure through the optimisation process. In the context of the revision of its present recommendations, the Commission is reenforcing the emphasis on protection of the individual with the adoption of an equity-based system that recognizes individual rights and a basic level of health protection. Another advancement is the role that is now recognised to 'stakeholders involvement' in the optimisation process as a mean to improve the quality of the decision aiding process for identifying and selecting protection actions considered as being accepted by all those involved.

    Antiphospholipid syndrome is an autoimmune disorder characterized by recurrent venous or arterial thrombosis and/or pregnancy-related problems associated with persistently elevated levels of antiphospholipid antibodies. The kidney is a major target organ in both primary and secondary antiphospholipid syndrome. This review describes several aspects of the renal involvement in the primary form of the syndrome, in particular the histological pattern of the so-called antiphospholipid syndrome nephropathy (APSN). APSN is a vascular nephropathy characterized by small vessel vaso-occlusive lesions associated with fibrous intimal hyperplasia of interlobular arteries, recanalizing thrombi in arteries and arterioles, and focal atrophy, a constellation of morphological lesions suggestive of primary antiphospholipid syndrome.

    Trichotillomania is a neglected psychiatric disorder characterized by the urge to pull out the hair, the eyebrows or any other hair, but rarely the eyelashes. In the Diagnostic and Statistical Manual of Mental Disorders it is defined as habits and pulses disturbance. We here report the case of a girl with trichotillomania involving her left eyelashes due to low self-esteem. The disease may be episodic but it is usually chronic and difficult to treat. Given the possible clinical and psychiatric complications, early and accurate diagnosis is essential. Cognitive-behavioral therapy is the gold standard treatment.

    A review and evaluation is given of the experimental data which are available for charge exchange processes involving iron ions and neutral H, H 2 and He. Appropriate scaling laws are presented, and their accuracy estimated for these systems. A bibliography is given of available data sources, as well as of useful data compilations and review articles. A procedure is recommended for providing single approximate formulae to the fusion community to describe total cross sections for electron capture by partially-stripped Fe/sup q+/ ions in collisions with H, H 2 and He, based on the scaling relationships suggested by Janev and Hvelplund

  18. A semilinear control problem involving homogenization

    2001-01-01

    Full Text Available We consider a control problem involving a semilinear elliptic equation with a uniformly Lipschitz non-linearity and rapidly oscillating coefficients in a bounded domain of $mathbb{R}^N$. The control is distributed on a compact subset interior to the domain. Given an $N-1$ dimensional hypersurface at the interior of the domain not intersecting the control zone, the trace of the solution on the curve has to be controlled. We prove that there exists a limit control as the homogenization parameter converges to zero, which results as the limit of fixed points for controllability problems. We link this limit control with the corresponding homogenized problem.

    We retrospectively collected the characteristics of 80 consecutive adult patients with biologically confirmed measles during a recent epidemic in France. We report on the frequency and severity of liver involvement in adult patients with measles. In our experience, measles in adults was not severe and hepatitis was not correlated with severe cases or bacterial infection. Therefore, hepatitis should be regarded as a usual symptom rather than a complication of measles infection in adults. Copyright © 2013 International Society for Infectious Diseases.

    Full Text Available Antiphospholipid syndrome is an autoimmune disorder characterized by vascular thromboses and pregnancy morbidity associated with antiphospholipid antibodies: lupus anticoagulant, IgG or IgM anticardiolipin or anti-beta 2-glycoprotein I. The kidney is one of the major target organs in antiphospholipid syndrome (APS. However, beyond the known involvement of the kidney in primary and associated APS, we may be observing a new form of APS within the context of renal failure. This review describes the classical kidney manifestations of APS and provides new considerations to be taken into account.

    Involvement of the central nervous system in acquired immune deficiency syndrome (AIDS) is usually due to opportunistic infections; these frequently offer a difficult differential diagnostic problem. Imaging methods play an important part in the elucidation of symptoms. CT and MR findings were analysed in 13 patients with AIDS and neurological symptoms. Some infections of the central nervous system (encephalitis of unknown aetiology, cytomegalic encephalitis, meningitis) may show cerebral atrophy or even no morphological changes. Toxoplasmosis and PML are the most common opportunistic infections typical changes on CT and MR may lead to diagnosis. MR offers advantages compared with CT in its higher sensitivity for the demonstration even of small lesions. (orig.) [de

    Full Text Available Discrimination, whether institutionalised or not, is described as the expression of prejudice, which, it is argued, is derived from projectionism, or the supposition that one's own perception coincides with reality and is therefore the only valid one. It is the result of naive ignorance of the world view(s by which human attitudes are shaped. By means of the ecologically congenial concepts of interrelatedness and holism, it is here argued as an alternative that social involvement is (or, should be an intrinsic part of conservation. A possible model for the purpose and some practical considerations are suggested.

    Full Text Available In endodontic infections a lot of different microrganisms can be time inside dentinal tubules to support such infections. Most of these are Gram negative anaerobes bacteria able to induce an immune response that is the apparent cause of periapical lesion, but also Gram positive facultative aerobic species and fungi of the genus Candida.They play an important role in pain but also in bone periapical resorption. Therefore, the exact knowledge and the subsequent elimination of the microrganisms involved by the system of root canals, although difficult to achieve completely, is essential for the resolution of apical periodontitis.

    2012-11-01

    Full Text Available Coronaviruses are single stranded, positive sense RNA viruses, which induce the rearrangement of cellular membranes upon infection of a host cell. This provides the virus with a platform for the assembly of viral replication complexes, improving efficiency of RNA synthesis. The membranes observed in coronavirus infected cells include double membrane vesicles. By nature of their double membrane, these vesicles resemble cellular autophagosomes, generated during the cellular autophagy pathway. In addition, coronavirus infection has been demonstrated to induce autophagy. Here we review current knowledge of coronavirus induced membrane rearrangements and the involvement of autophagy or autophagy protein microtubule associated protein 1B light chain 3 (LC3 in coronavirus replication.

    A unique characteristic of mammalian sperm thermotaxis is extreme temperature sensitivity, manifested by the capacity of spermatozoa to respond to temperature changes of functional approaches that opsins are present in human and mouse spermatozoa at specific sites, which depend on the species and the opsin type, and that they are involved in sperm thermotaxis via two signalling pathways—the phospholipase C and the cyclic-nucleotide pathways. Our results suggest that, depending on the context and the tissue, mammalian opsins act not only as photosensors but also as thermosensors. PMID:26537127

    Localized scleroderma (LoSc), also known as morphea, is a rare fibrosing disorder of the skin and underlying tissues. Sclerosis is mainly limited to the skin, but subcutaneous tissue, fascia, and underlying muscles and bone may also be involved. In some cases, systemic manifestation with visceral abnormalities may occur. Several publications have focused on significant aspects of LoSc: genetics, immunity, epidemiology, scoring systems, and unification of classifications. Clinical studies featuring large cohorts with the disease published by various international study groups have been of great value in furthering the diagnostic and therapeutic management of LoSc.

    In 1986 British Columbia Hydro made a commitment to perform annual dam failure simulations based on the Emergency Preparedness Plans. Over the last 7 years nine such exercises have been completed. Each year the level of complexity of the exercises has increased, and along with it, the number of organizations outside of B.C. Hydro that participate in the exercise events has also increased. There has been a shift in attitudes, both internally and externally, towards these exercises. It is described how British Columbia Hydro was able to involve the communities downstream of its dams and encourage their participation in emergency planning and coordination. B.C. Hydro's process for involving a community in its emergency exercises starts with an invitation to the emergency coordinator in each affected community to attend an exercise planning meeting. Communities have occasionally declined to participate, the most common reasons being insufficiently developed emergency plans, budget prohibiting the cost of the exercise, or for political reasons. 2 refs., 1 tab

  10. Fusion excitation functions involving transitional nuclei

    1995-08-01

    Measurements of fusion excitation functions involving transitional nuclei {sup 78}Kr and {sup 100}Mo showed a different behavior at low energies, if compared to measurements with {sup 86}Kr and {sup 92}Mo. This points to a possible influence of nuclear structure on the fusion process. One way to characterize the structure of vibrational nuclei is via their restoring force parameters C{sub 2} which can be calculated from the energy of the lowest 2{sup +} state and the corresponding B(E2) value. A survey of the even-even nuclei between A = 28-150 shows strong variations in C{sub 2} values spanning two orders of magnitude. The lowest values for C{sub 2} are observed for {sup 78}Kr, {sup 104}Ru and {sup 124}Xe followed by {sup 74,76}Ge, {sup 74,76}Se, {sup 100}Mo and {sup 110}Pd. In order to learn more about the influence of {open_quotes}softness{close_quotes} on the sub-barrier fusion enhancement, we measured cross sections for evaporation residue production for the systems {sup 78}Kr + {sup 104}Ru and {sup 78}Kr + {sup 76}Ge with the gas-filled magnet technique. For both systems, fusion excitation functions involving the closed neutron shell nucleus {sup 86}Kr were measured previously. The data are presently being analyzed.

    Objective Osteogenesis imperfecta is a hereditary disease resulting from mutation in type I procollagen genes. One of the extra skeletal manifestations of this disease is cardiac involvement. The prevalence of cardiac involvement is still unknown in the children with osteogenesis imperfecta. The present study aimed to investigate the prevalence of cardiovascular abnormalities in these patients. Methods 24 children with osteogenesis imperfecta and 24 normal children who were matched with the patients regarding sex and age were studied. In both groups, standard echocardiography was performed, and heart valves were investigated. Dimensions of left ventricle, aorta annulus, sinotubular junction, ascending and descending aorta were measured and compared between the two groups. Findings The results revealed no significant difference between the two groups regarding age, sex, ejection fraction, shortening fraction, mean of aorta annulus, sinotubular junction, ascending and descending aorta, but after correction based on the body surface area, dimensions of aorta annulus, sinotubular junction, ascending and descending aorta in the patients were significantly higher than those in the control group (P25 mmHg and one patient had pulmonary insufficiency with indirect evidence of pulmonary hypertension. According to Z scores of aorta annulus, sinotubular junction and ascending aorta, 5, 3, and 1 out of 24 patients had Z scores >2 respectively. Conclusion The prevalence of valvular heart diseases and aortic root dilation was higher in children with osteogenesis imperfecta. In conclusion, cardiovascular investigation is recommended in these children. PMID:24800009

    To determine the different radiological findings in the lung of children presenting human ummunodeficiency virus (HIV) infection. We assess the different radiological patterns and their prevalence. The study deals with 58 children presenting HIV infection. All underwent plain chest radiography at some time during the course of their disease to determine the cause of different respiratory symptoms (dyspnea, fever, cough, etc.).Bronchial lavage was performed in all the children who required intubation due to severe respiratory distress. The results of chest X-ray were normal in 29 children despite the existence of pulmonary symptomatology. The other 29 patients presented pulmonary, including 21 cases of pneumonia (36,2%) in 16 patients, in seven of whom the pathogen was determined by blood culture. Four cases of Pneumocystis carinii (6.89%) were diagnosed by means of bronchial lavage. There were nine children with interstitial pneumonitis, five of the lym-phoid variant (8.62%) and four of unknown origin (6.89%). In contrast to the findings in adults, we have had no cases of pulmonary tuberculosis among our patients The rates of morbidity and mortality among HIV-infected children are associated with lung involvement. However, the prevalence has decreased progressively since the introduction of antiviral agents. Recurrent bacterial pneumonia and opportunistic Pneumocystis carinii infection are the most common types of acute pulmonary involvement. Interstitial pneumonitis usually develops a chronic course.

    Full Text Available Previous research suggests that action language is comprehended by activating the motor system. We report a study, investigating a critical question in this research field: Do negative sentences activate the motor system? Participants were exposed to sentences in the affirmation and negation forms while the zygomatic muscle activity on the left side of the face was continuously measured (Electromyography technique: EMG. Sentences were descriptions of emotional expressions that mapped either directly upon the zygomatic muscle (e.g., ‘I am smiling’ or did not (e.g., ‘I am frowning’. Reading sentences involving the negation of the activity of a specific muscle (zygomatic major - I am not smiling is shown to lead to the inhibition of this muscle. Reading sentences involving the affirmative form instead (I am smiling leads to the activation of zygomatic mucle. In contrast, sentences describing an activity that is irrelevant to the zygomatic muscle (e.g., ‘I am frowning’ or ‘I am not frowning’ produce no muscle activity. These results extend the range of simulation models to negation and by implication to an abstract domain. We discuss how this research contributes to the grounding of abstract and concrete concepts.

    1984-12-01

    Full Text Available A group of patients with Bell's palsy were studied in order to disclose the presence of subclinical peripheral nerve involvement. 20 patients, 8 male and 12 female, with recent Bell's palsy as their unique disease were examined, in all cases other causes of polyneuropathy were ruled out. Patients were investigated with CSF examination, facial nerve latencies in the affected and in the sound sides, and maximal motor nerve conduction velocities, as well as motor terminal latencies from the right median and peroneal nerves. CSF laboratory examination was normal in all cases. Facial nerve latencies were abnormal in all patients in the affected side, and they differed significantly from those of control group in the clinically sound side. Half of the patients showed abnormal values in the maximal motor nerve conduction velocities and motor terminal latencies of the right median and peroneal nerves. These results agree with previous reports which have pointed out that other cranial nerves may be affected in Bell's palsy. However, we have found a higher frequency of peripheral nerve involvement in this entity. These findings, support the hypothesis that in some patients Bell's palsy is the component of a more widespread disease, affecting other cranial and peripheral nerves.

    'In recent years Uncle Sam has been asking citizens for their help in improving the environment. The government is learning that with public input it can better prioritize environmental problems and more effectively direct limited funding.' The National Environmental Policy Act (NEPA), like many other government regulations, is a 'living law.' Although there are agency and Council guidelines, it is practical application, based on past practices and case law that refines the Act's broad concepts. The specifics of how to meet requirements are constantly being honed and melded to fit the unique situational needs of an agency, a project, or a public. This fluidity presents a challenge for stakeholder involvement activities. Communication practioners and project managers may have room for creativity and customized approaches, but they also find less than clear direction on what it takes to successfully avoid challenges of non-compliance. Because of the continuing uncertainty on how to involve the public meaningfully, it is vital to share important lessons learned from NEPA projects. The following practical suggestions are derived primarily from experiences with the Department of Energy's first ever complex-wide and site-specific environmental impact statement (EIS)-the Programmatic Spent Nuclear Fuel Management and Idaho National Engineering Laboratory Environmental Restoration and Waste Management Programs EIS (SNF ampersand INEL EIS)

    In the early morning of Dec. 16, 1991, a severe accident occurred when a passenger vehicle traveling in the wrong direction collided with a tractor trailer carrying 24 nuclear fuel assemblies in 12 containers on Interstate 1-91 in Springfield, Massachusetts. This paper documents the mechanical circumstances of the accident and the physical environment to which the containers were exposed and the response of the containers and their contents. The accident involved four impacts where the truck was struck by the car, impacted on the center guardrail, impacted on the outer concrete barrier and came to rest against the center guardrail. The impacts were followed by a fire that began in the engine compartment, spread to the.tractor and cab, and eventually spread to the trailer and payload. The fire lasted for about three hours and the packages were involved in the fire for about two hours. As a result of the fire, the tractor-trailer was completely destroyed and the packages were exposed to flames with temperatures between 1300 degrees F and 1800 degrees F. The fuel assemblies remained intact during the accident and there was no release of any radioactive material during the accident. This was a very severe accident; however, the injuries were minor and at no time was the public health and safety at risk

    The "involvement effect" refers to the finding that controlling for gambling involvement often reduces or eliminates frequently observed game-specific associations with problem gambling. In other words, broader patterns of gambling behavior, particularly the number of types of games played over a defined period, contribute more to problem gambling than playing specific games (e.g., lottery, casino, Internet gambling). This study extends this burgeoning area of inquiry in three primary ways. First, it tests independently and simultaneously the predictive power of two gambling patterns: breadth involvement (i.e., the number of games an individual plays) and depth involvement (i.e., the number of days an individual plays). Second, it includes the first involvement analyses of actual betting activity records that are associated with clinical screening information. Third, it evaluates and compares the linearity of breadth and depth effects. We conducted analyses of the actual gambling activity of 1,440 subscribers to the bwin.party gambling service who completed an online gambling disorder screen. In all, 11 of the 16 games we examined had a significant univariate association with a positive screen for gambling disorder. However, after controlling for breadth involvement, only Live Action Internet sports betting retained a significant relationship with potential gambling-related problems. Depth involvement, though significantly related to potential problems, did not impact game-based gambling disorder associations as much as breadth involvement. Finally, breadth effects appeared steeply linear, with a slight quadratic component manifesting beyond four games played, but depth effects appeared to have a strong linear component and a slight cubic component.

    Using data from 182 dual-earner couples experiencing the transition to parenthood, this study examined associations between prenatal involvement, gender role beliefs, and maternal gatekeeping and new fathers’ involvement in child health care. Results indicated that prenatal father involvement was associated with both fathers’ direct engagement in child health care and fathers’ perceived influence in child health-related decision-making. Fathers also demonstrated greater direct engagement in child health care when mothers held more nontraditional beliefs about gender roles. Moreover, when mothers were more encouraging of fathers’ involvement in childrearing, fathers felt more influential in child health-related decision-making, whereas when mothers engaged in greater gate closing behavior, fathers with more traditional gender role beliefs felt less influential in child health-related decision-making. This study suggests that fathers’ prenatal involvement, mothers’ beliefs, and maternal gatekeeping may play a role in the development of new fathers’ involvement in child health care at the transition to parenthood.

    2008-01-01

    A five-year-old girl developed hoarseness with gradual worsening at the age of eight months. Three months later, she underwent bronchoscopy in which papillomas in the vocal cords, larynx and trachea were observed. Because of serious bronchospasm crises and respiratory failure, she needed several hospitalizations, definitive tracheostomy and multiple endoscopic procedures for papilloma excision. The most recent chest radiography (Figure A) and computed tomography (CT) scans (Figures B and C) showed a nodule inside the trachea and multiple pulmonary nodules, cysts and consolidations. The anatomopathological findings from curettage of the lesions revealed benign squamous-cell papillomas. Recurrent respiratory papillomatosis (RRP) is directly related to the human papillomavirus (HPV). Its spread to the lower airways is uncommon, with involvement of trachea and/or proximal bronchi in 5% of the patients, and extension to the lungs in only 1% of the cases. (author)

    In this paper the authors consider the personnel problems that may arise for defined contribution plan sponsors if major market corrections cause older employees to delay retirement beyond previous expectations. We move from that basic premise to argue that, given the continued evolution from defined benefit (DB) to defined contribution (DC) retirement plans, employers need to be more "proactive" in educating their employees about their retirement planning. A human resources perspective is used to support this argument, apart from and in addition to legal considerations such as ERISA Section 404(c). Specifics of employer involvement and its place as a component of an organization's culture are discussed. Finally, recommendations are given for employers to consider.

    A case of peculiar chondroblastoma involving multiple tarsal bones in a 49-year-old woman is described. The patient presented with pain and swelling of the right foot. Radiographs revealed a lytic expansile lesion of medial, intermediate, and lateral cuneiform bones, navicular, cuboid, and tarsal bones of the right foot, indicating a malignant tumor. Biopsies demonstrated a diffuse proliferation of round cells with eccentric and indented nuclei with longitudinal grooves and eosinophilic cytoplasm. Atypia was prominent, but mitotic figures were rare. The stroma was chondroid with focal chicken-wire calcification. On electron microscopy, the tumor exhibited chondroblastic features. The patient is alive with the tumor 7 years after radiotherapy. The tumor is considered a chondroblastoma with low malignant potential. (orig.)

    2013-08-01

    Full Text Available For millions of years, vertebrates have been continuously exposed to infection by retroviruses. Ancient retroviral infection of germline cells resulted in the formation and accumulation of inherited retrovirus sequences in host genomes. These inherited retroviruses are referred to as endogenous retroviruses (ERVs, and recent estimates have revealed that a significant portion of animal genomes is made up of ERVs. Although various host factors have suppressed ERV activation, both positive and negative functions have been reported for some ERVs in normal and abnormal physiological conditions, such as in disease states. Similar to other complex diseases, ERV activation has been observed in prion diseases, and this review will discuss the potential involvement of ERVs in prion diseases.

    2014-11-01

    Increasingly, pharmacy workplaces are larger organizations that rely on policy and clinical guidelines to direct professional practice. Often, cost-cutting, profit-making, service-improving, and process-streamlining ideas are needed but difficult to identify or implement. By involving employees more closely in the change process using participative management (PM), managers reap tremendous reward. PM focuses on employee collaboration to develop and implement consistent, effective policies and procedures. This process recognizes employees' creative, emotional and intellectual needs and often improves the organization's public face as well. In addition, consumers perceive this approach to be socially responsible management. Managers can implement PM in a number of ways, applying it to problems or processes. PM has some pitfalls, but overall, if the workplace culture adapts to accommodate its principles, PM usually provides numerous benefits for organizations, their employees, and their customers.

  9. Concrescent triplets involving primary anterior teeth

    2013-01-01

    Full Text Available Odontogenesis is a complex process wherein more than 200 genes are known to play a significant role in tooth development. An imbalance can lead to an abnormality in the number, size, shape or structure of the developing tooth/teeth. The presence of an extra dental lamina forms a supernumerary tooth. The supernumerary teeth are of two types: A rudimentary tooth where the supernumerary tooth does not resemble any tooth in the normal series or a supplemental tooth in which this anomalous tooth resembles one in the normal series. It is also very rare to encounter triple teeth in primary dentition. The union of these teeth may be through fusion, gemination, concrescence or a combination of fusion and gemination. Presented is a rare case of concrescence involving maxillary deciduous incisors and a supplemental tooth in a 7-year-old boy. The differential diagnosis, etiology, and complications of primary anterior triple teeth are discussed.

    Mutiple mieloma (MM) cells are rarely found in extramedullary sites. The sites of extramedullary dissemination reported in the literature are spleen, liver, lymph nodes, kidneys, thyroid gland, adrenal gland, ovary, tests, lung, pleura, pericardium, intestinal tract and skin. We report a case in which the myeloma was diagnosed after we discovered the presence of monoclonal plasma cells in the bronchoalveolar lavage fluid (BAL). Matherial and method: a case in which diagnosis was established from bronchoalveolar lavage (BAL) fluid demonstrating the presence of monoclonal plasma cells in Craiova Pneumology Departament. Analysis of BAL fluid for the presence of plasma cells and for cytoplasmic immunoglobulin DNA provides a noninvasive means of establishing the diagnosis. Pulmonary parenchyma is an uncommon site of extramedullary involvement in multiple myeloma. Interstitial lung disease as pulmonary manifestation of multiple myeloma is even rarer; only isolated cases with histological proofs have been reported in the literature.

  11. Yeast ABC proteins involved in multidrug resistance.

    2014-03-01

    Pleiotropic drug resistance is a complex phenomenon that involves many proteins that together create a network. One of the common mechanisms of multidrug resistance in eukaryotic cells is the active efflux of a broad range of xenobiotics through ATP-binding cassette (ABC) transporters. Saccharomyces cerevisiae is often used as a model to study such activity because of the functional and structural similarities of its ABC transporters to mammalian ones. Numerous ABC transporters are found in humans and some are associated with the resistance of tumors to chemotherapeutics. Efflux pump modulators that change the activity of ABC proteins are the most promising candidate drugs to overcome such resistance. These modulators can be chemically synthesized or isolated from natural sources (e.g., plant alkaloids) and might also be used in the treatment of fungal infections. There are several generations of synthetic modulators that differ in specificity, toxicity and effectiveness, and are often used for other clinical effects.

    2012-06-01

    Full Text Available A two-dimensional scale, called ECID Scale, is presented in this paper. The scale is based on a comprehensive model and captures the two antecedent factors of purchase-related involvement, namely whether motivation is intrinsic or extrinsic and whether risk is perceived as low or high. The procedure of scale development and item selection is described. The scale turns out to perform well in terms of validity, reliability, and objectivity despite the use of a small set of items – four each – allowing for simultaneous measurements of up to ten purchases per respondent. The procedure of administering the scale is described so that it can now easily be applied by both, scholars and practitioners. Finally, managerial implications of data received from its application which provide insights into possible strategic marketing conclusions are discussed.

    We studied the dialogue between telephone operators at medical emergency communication centres in Norway and parents of children later diagnosed with sudden infant death syndrome. The aim was to understand how the parents experienced the communication with the telephone operators. The qualitative method involved semi-structured interviews. We interviewed six respondents from urban areas and five from rural areas. An important finding was that all the parents were satisfied with the resuscitation instructions they received. It was also perceived as important that the emergency operators expressed empathy and care. We believe that it is not merely the quality of the resuscitation attempts that the operators' efforts should be measured against. It is also important that the operators provide good explanations and express emotional support. Our findings indicate that this will be enormously appreciated, even if callers do not feel that they are capable of performing optimum resuscitation.

    Forensic odontology is one of three primary identifiers designated by Interpol to identify victims of mass casualty events. Forensic odontology is involved in all five phases-Scene, Postmortem, Antemortem, Reconciliation and Debrief. Forward planning, adequate funding, international cooperation and standardization are essential to guarantee an effective response. A Standard Operation Procedure should be utilized to maximize quality, facilitate occupation and health issues, maintain security and form a structure to the relief program. Issues that must be considered in the management of the forensic odontology component of disaster victim identification are given in "Appendix 1". Each stage of the disaster, from initial notification to debrief, is analyzed and a comprehensive checklist of actions suggested.

    2007-07-03

    Methods and materials for studying the effects of a newly identified human gene, APOAV, and the corresponding mouse gene apoAV. The sequences of the genes are given, and transgenic animals which either contain the gene or have the endogenous gene knocked out are described. In addition, single nucleotide polymorphisms (SNPs) in the gene are described and characterized. It is demonstrated that certain SNPs are associated with diseases involving lipids and triglycerides and other metabolic diseases. These SNPs may be used alone or with SNPs from other genes to study individual risk factors. Methods for intervention in lipid diseases, including the screening of drugs to treat lipid-related or diabetic diseases are also disclosed.

    2015-01-01

    CNS disease, or central neuropsychiatric lupus erythematosus (cNPSLE), occurs frequently in pediatric lupus, leading to significant morbidity and poor long-term outcomes. Diagnosing cNPSLE is especially difficult in pediatrics; many current diagnostic tools are invasive and/or costly, and there are no current accepted screening mechanisms. The most complicated aspect of diagnosis is differentiating primary disease from other etiologies; research to discover new biomarkers is attempting to address this dilemma. With many mechanisms involved in the pathogenesis of cNPSLE, biomarker profiles across several modalities (molecular, psychometric and neuroimaging) will need to be used. For the care of children with lupus, the challenge will be to develop biomarkers that are accessible by noninvasive measures and reliable in a pediatric population. PMID:26079959

    2004-01-01

    A 37-years old Pakistani lady, who had previously undergone one cesarean delivery and one uterine curettage, was admitted to the labor ward at 29 weeks of gestation with history of sudden severe painless vaginal bleeding from a sonographically diagnosed placenta pervia. An immediate cesarean was performed and a live male infant was delivered. The placenta was morbidly adherent to the lower uterine segment and attempts at removal caused torrential bleeding, necesstiating cesarean hysterectomy. In addition, attempts to dissect the bldder from lower uterine segment was unsuccessful and, hence, the diagnosis of placenta percreta with involvement of urinary bladder was made. A modified posterior approach to the hyterectomy was carried out, with subsequent good recovery. (author)

    2016-01-01

    Full Text Available A 33-year-old man who presented with prolonged epigastric pain was referred to our hospital. He had experienced recurrent epistaxis and had a family history of hereditary hemorrhagic telangiectasia. Computed tomography and magnetic resonance imaging revealed splenomegaly and a 9 cm hypervascular mass in his spleen. Computed tomography also showed a pulmonary arteriovenous malformation and heterogeneous enhancement of the liver parenchyma, suggesting the presence of arteriosystemic shunts and telangiectases. Based on these findings, the patient was definitely diagnosed with hereditary hemorrhagic telangiectasia according to Curaçao criteria. He underwent splenectomy, and his symptoms disappeared after surgery. Pathological examination of the resected specimen revealed that the hypervascular lesion of the spleen was not a tumor but was composed of abnormal vessels associated with hereditary hemorrhagic telangiectasia. Symptomatic splenic involvement may be a rare manifestation of hereditary hemorrhagic telangiectasia but can be revealed by imaging modalities.

    2008-01-01

    Ischemic nephropathy is an important cause of renal failure.Sub-clinical renal function abnormalities may exist in patients with extra renal atherosclerosis and may precede the onset of overt ischemic nephropathy. To assess the impact of extrarenal atherosclerosis on the kidney, the study evaluated renal function in 50 subjects with differing degrees of peripheral atherosclerosis without manifest clinical or laboratory signs of ischemic nephropathy and renovascular hypertension.All laboratory testing including total LDL and HDL-cholesterol, triglycerides, ultrasonography with Doppler analysis for the localization of peripheral vascular disease (carotid and lower limb arteries), and non-invasive evaluation of renal function by radionuclide studies of renal plasma flow (MAG3 clearance) and glomerular filtration (DTPA clearance) were determined as well as smoking habit was recorded. By combining sonographic data on arterial tree stenosis (ATS), the subjects were grouped according to the atherosclerotic vascular damage (ATS involvement). The results showed no change in plasma creatinine while DTPA clearance was increased from 91.58±26.53 to 93.47±24.82 ml/min/1.73 m. MAG3 clearance was progressively declined with the severity of vascular damage from 244.86 ± 60.60 to 173.59±58.74 ml/min/1.73 m.Stepwise, multiple regression analysis indicated that MAG3 clearance was best explained by ATS involvement (standardized B coefficient -0.40; P< 0.001), smoking habit (-0.34;P=0.004) and serum LDL-cholesterol (-0.24; P<0.035).It could be concluded that the renal hemodynamic profile in atherosclerotic patients might constitute functional evidence of the silent phase of ischemic renal disease. The findings suggest that renal function should be carefully assessed in patients with extrarenal atherosclerosis, particularly in those with classic cardiovascular risk factors

    This is a systematic review of suicide and homicide-suicide events involving aircraft. In aeromedical literature and in the media, these very different events are both described as pilot suicide, but in psychiatry they are considered separate events with distinct risk factors. Medical databases, internet search engines, and aviation safety databases were searched in a systematic way to obtain relevant cases. Relevant articles were searched for additional references. There were 65 cases of pilot suicide and 6 cases of passengers who jumped from aircraft found. There were also 18 cases of homicide-suicide found involving 732 deaths. Pilots perpetrated 13 homicide-suicide events. Compared to non-aviation samples, a large percentage of pilot suicides in this study were homicide-suicides (17%). Homicide-suicide events occur extremely rarely. However, their impact in terms of the proportion of deaths is significant when compared to deaths from accidents. There is evidence of clustering where pilot suicides occur after by media reports of suicide or homicide-suicide. Five of six homicide-suicide events by pilots of commercial airliners occurred after they were left alone in the cockpit. This, along with a sixth incident in which active intervention by a Japan Air crew saved 147 lives, suggests that having two flight members in the cockpit is potentially protective. No single factor was associated with the risk for suicide or homicide-suicide. Factors associated with both events included legal and financial crises, occupational conflict, mental illness, and relationship stressors. Drugs and/or alcohol played a role in almost half of suicides, but not in homicide-suicides.

  3. Neurobiological mechanisms involved in sleep bruxism.

    2003-01-01

    Sleep bruxism (SB) is reported by 8% of the adult population and is mainly associated with rhythmic masticatory muscle activity (RMMA) characterized by repetitive jaw muscle contractions (3 bursts or more at a frequency of 1 Hz). The consequences of SB may include tooth destruction, jaw pain, headaches, or the limitation of mandibular movement, as well as tooth-grinding sounds that disrupt the sleep of bed partners. SB is probably an extreme manifestation of a masticatory muscle activity occurring during the sleep of most normal subjects, since RMMA is observed in 60% of normal sleepers in the absence of grinding sounds. The pathophysiology of SB is becoming clearer, and there is an abundance of evidence outlining the neurophysiology and neurochemistry of rhythmic jaw movements (RJM) in relation to chewing, swallowing, and breathing. The sleep literature provides much evidence describing the mechanisms involved in the reduction of muscle tone, from sleep onset to the atonia that characterizes rapid eye movement (REM) sleep. Several brainstem structures (e.g., reticular pontis oralis, pontis caudalis, parvocellularis) and neurochemicals (e.g., serotonin, dopamine, gamma aminobutyric acid [GABA], noradrenaline) are involved in both the genesis of RJM and the modulation of muscle tone during sleep. It remains unknown why a high percentage of normal subjects present RMMA during sleep and why this activity is three times more frequent and higher in amplitude in SB patients. It is also unclear why RMMA during sleep is characterized by co-activation of both jaw-opening and jaw-closing muscles instead of the alternating jaw-opening and jaw-closing muscle activity pattern typical of chewing. The final section of this review proposes that RMMA during sleep has a role in lubricating the upper alimentary tract and increasing airway patency. The review concludes with an outline of questions for future research.

    Full Text Available Abstract Background Hyaluronidases belong to a class of enzymes that degrade, predominantly, hyaluronan. These enzymes are known to be involved in physiological and pathological processes, such as tumor growth, infiltration and angiogenesis, but their exact role in tumor promotion or suppression is not clear yet. Advanced colorectal cancer is associated with elevated amounts of hyaluronan of varying size. The aim of the present study was therefore to illuminate the importance of hyaluronidases in colon carcinoma progression. Methods The patients' samples (macroscopically normal and cancerous were subjected to sequential extraction with PBS, 4 M GdnHCl and 4 M GdnHCl - 1% Triton X-100. The presence of the various hyaluronidases in the extracts was examined by zymography and western blotting. Their expression was also examined by RT-PCR. Results Among hyaluronidases examined, Hyal-1, -2, -3 and PH-20 were detected. Their activity was higher in cancerous samples. Hyal-1 and Hyal-2 were overexpressed in cancerous samples, especially in advanced stages of cancer. Both isoforms were mainly extracted with PBS. Hyal-3 was observed only in the third extract of advanced stages of cancer. PH-20 was abundant in all three extracts of all stages of cancer. The expression of only Hyal-1 and PH-20 was verified by RT-PCR. Conclusion A high association of hyaluronidases in colorectal cancer was observed. Each hyaluronidase presented different tissue distribution, which indicated the implication of certain isoforms in certain cancer stages. The results provided new evidence on the mechanisms involved in the progression of colorectal cancer.

    Full Text Available Abstract Background Family doctors should care for individuals in the context of their family. Family has a powerful influence on health and illness and family interventions have been shown to improve health outcomes for a variety of health problems. The aim of the study was to investigate the Estonian family doctors' (FD attitudes to the patients' family-related issues in their work: to explore the degree of FDs involvement in family matters, their preparedness for management of family-related issues and their self-assessment of the ability to manage different family-related problems. Methods A random sample (n = 236 of all FDs in Estonia was investigated using a postal questionnaire. Altogether 151 FDs responded to the questionnaire (response rate 64%, while five of them were excluded as they did not actually work as FDs. Results Of the respondents, 90% thought that in managing the health problems of patients FDs should communicate and cooperate with family members. Although most of the family doctors agreed that modifying of the health damaging risk factors (smoking, alcohol and drug abuse of their patients and families is their task, one third of them felt that dealing with these problems is ineffective, or perceived themselves as poorly prepared or having too little time for such activities. Of the respondents, 58% (n = 83 were of the opinion that they could modify also relationship problems. Conclusions Estonian family doctors are favourably disposed to involvement in family-related problems, however, they need some additional training, especially in the field of relationship management.

    Full text: Full text: Fusion, the process that powers the sun and stars, offers a solution to the world's long-term energy needs: providing large scale energy production with zero greenhouse gas emissions, short-lived radio-active waste compared to conventional nuclear fission cycles, and a virtually limitless supply of fuel. Almost three decades of fusion research has produced spectacular progress. Present-day experiments have a power gain ratio of approximately 1 (ratio of power out to power in), with a power output in the 10's of megawatts. The world's next major fusion experiment, the International Thermonuclear Experimental Reactor (ITER), will be a pre-prototype power plant. Since announcement of the ITER site in June 2005, the ITER project, has gained momentum and political support. Despite Australia's foundation role in the field of fusion science, through the pioneering work of Sir Mark Oliphant, and significant contributions to the international fusion program over the succeeding years, Australia is not involved in the ITER project. In this talk, the activities of a recently formed consortium of scientists and engineers, the Australian ITER Forum will be outlined. The Forum is drawn from five Universities, ANSTO (the Australian Nuclear Science and Technology Organisation) and AINSE (the Australian Institute for Nuclear Science and Engineering), and seeks to promote fusion energy in the Australian community and negotiate a role for Australia in the ITER project. As part of this activity, the Australian government recently funded a workshop that discussed the ways and means of engaging Australia in ITER. The workshop brought the research, industrial, government and general public communities, together with the ITER partners, and forged an opportunity for ITER engagement; with scientific, industrial, and energy security rewards for Australia. We will report on the emerging scope for Australian involvement

    The United Kingdom Atomic Energy Authority (UKAEA) was established in the 1950's to pioneer the development of nuclear energy within the UK. Today its primary mission is to decommission UK's former nuclear research sites and restore its environment in a way that is safe and secure, environmentally friendly, value for money and publicly Acceptable. UKAEA Dounreay celebrated its 50 birthday in 2005, having pioneered the development of fast reactor technology since 1955. Today the site is now leading the way in decommissioning. The Dounreay nuclear site licence covers an area of approximately 140 acres and includes 3 reactors: the Dounreay Material Test Reactor (DMTR), the Dounreay Fast Reactor (DFR), and the Prototype Fast Reactor (PFR). In addition there are 180 facilities on site which have supported the fast reactor programme, including a fuel reprocessing capability, laboratories and administration buildings. The reactors are now all in advanced stages of decommissioning. In October 2000 the Dounreay Site Restoration Plan (DSRP) was published to provide a framework for the site's restoration. The plan's objective was to reduce the site's hazards progressively by decontaminating and dismantling the plant, equipment and facilities, remediating contaminated ground and treating and packaging waste so it is suitable for long term storage or disposal. Whilst hailed as the most detailed plan integrating some 1500 activities and spanning 60 years it was criticised for having no stakeholder involvement. In response to this criticism, UKAEA developed a process for public participation over the following 2 years and launched its stakeholder engagement programme in October 2002. In order to provide a larger platform for the engagement process an advertisement was placed in the Scottish media inviting people to register as stakeholders in the Dounreay Site Restoration Plan. The stakeholder list now total over 1000. In October 2002 UKAEA launched their commitment to public

    1978-05-01

    The study was undertaken to define in a quantitative nonjudgmental technical manner the abnormal environments to which a large package (total weight over 2 tons) would be subjected as the result of a transportation accident. Because of this package weight, air shipment was not considered as a normal transportation mode and was not included in the study. The abnormal transportation environments for shipment by motor carrier and train were determined and quantified. In all cases the package was assumed to be transported on an open flat-bed truck or an open flat-bed railcar. In an earlier study, SLA-74-0001, the small-package environments were investigated. A third transportation study, related to the abnormal environment involving waterways transportation, is now under way at Sandia Laboratories and should complete the description of abnormal transportation environments. Five abnormal environments were defined and investigated, i.e., fire, impact, crush, immersion, and puncture. The primary interest of the study was directed toward the type of large package used to transport radioactive materials; however, the findings are not limited to this type of package but can be applied to a much larger class of material shipping containers.

    Researchers have recently shown an increased interest in free radicals and their role in the tumor microenvironment. Free radicals are molecules with high instability and reactivity due to the presence of an odd number of electrons in the outermost orbit of their atoms. Free radicals include reactive oxygen and nitrogen species, which are key players in the initiation and progression of tumor cells and enhance their metastatic potential. In fact, they are now considered a hallmark of cancer. However, both reactive species may contribute to improve the outcomes of radiotherapy in cancer patients. Besides, high levels of reactive oxygen species may be indicators of genotoxic damage in non-irradiated normal tissues. The purpose of this article is to review recent research on free radicals and carcinogenesis in order to understand the pathways that contribute to tumor malignancy. This review outlines the involvement of free radicals in relevant cellular events, including their effects on genetic instability through (growth factors and tumor suppressor genes, their enhancement of mitogenic signals, and their participation in cell remodeling, proliferation, senescence, apoptosis, and autophagy processes; the possible relationship between free radicals and inflammation is also explored. This knowledge is crucial for evaluating the relevance of free radicals as therapeutic targets in cancer.

    Pyodermatitis-pyostomatitis vegetans (PPV) is a rare chronic disorder often associated with inflammatory bowel disease. We report an isolated case involving the oral, labial and nasal mucosa. A 28-year-old man, in good general condition, presented with a 2-year history of painless stomatitis. The physical examination revealed pustular and exophytic lesions of the jugal, gingival and palatine mucosa on an erythematous background, as well as some pustular and crusted lesions of the lower lip and nostrils. Histopathological analysis revealed epithelial hyperplasia and a suprabasal cleft with some signs of acantholysis and numerous neutrophils and eosinophils. Direct and indirect immunofluorescence assay was negative. There was no associated bowel disease. We concluded on a diagnosis of PPV of younger subjects. The lesions disappeared with oral corticosteroids but with steroid dependency. PPV is a rare dermatosis associated in more than 75% of cases with inflammatory bowel disease, usually ulcerative colitis. Lesions of the oral mucosa are a constant finding and are characterised by aseptic pustules on an erythematous background. Skin lesions are pustular and more or less exophytic. To our knowledge, there have been no reports to date of intranasal lesions of PPV.

    1998-01-01

    The study focuses on incidents at Department of Energy facilities involving the migration of radioactive contaminants through protective clothing. The authors analyzed 68 occurrence reports for the following factors: (1) type of work, (2) working conditions, (3) type of anti-contamination material; (4) area of body or clothing contaminated; and (5) nature of spread of contamination. A majority of reports identified strenuous work activities such as maintenance, construction, or decontamination and decommissioning projects. The reports also indicated adverse working conditions that included hot and humid or cramped work environments. The type of anti-contamination clothing most often identified was cotton or water-resistant disposable clothing. Most of the reports also indicated contaminants migrating through perspiration-soaked areas, typically in the knees and forearms. On the basis of their survey, the authors recommend the use of improved engineering controls and resilient, breathable, waterproof protective clothing for work in hot, humid, or damp areas where the possibility of prolonged contact with contamination cannot be easily avoided or controlled. 1 ref., 6 figs., 1 tab

    2009-07-01

    Full Text Available Extracellular polymeric substances (EPS produced by microorganisms are a complex mixture of biopolymers primarily consisting of polysaccharides, as well as proteins, nucleic acids, lipids and humic substances. EPS make up the intercellular space of microbial aggregates and form the structure and architecture of the biofilm matrix. The key functions of EPS comprise the mediation of the initial attachment of cells to different substrata and protection against environmental stress and dehydration. The aim of this review is to present a summary of the current status of the research into the role of EPS in bacterial attachment followed by biofilm formation. The latter has a profound impact on an array of biomedical, biotechnology and industrial fields including pharmaceutical and surgical applications, food engineering, bioremediation and biohydrometallurgy. The diverse structural variations of EPS produced by bacteria of different taxonomic lineages, together with examples of biotechnological applications, are discussed. Finally, a range of novel techniques that can be used in studies involving biofilm-specific polysaccharides is discussed.

    Systemic lupus erythematosus (SLE) is a multisystem disorder which can affect the gastrointestinal (GI) system. Although GI symptoms can manifest in 50% of patients with SLE, these have barely been reviewed due to difficulty in identifying different causes. This study aims to clarify clinical characteristics, diagnosis and treatment of the four major SLE-related GI system complications: protein-losing enteropathy (PLE), intestinal pseudo-obstruction (IPO), hepatic involvement and pancreatitis. It is a systematic review using MEDLINE and EMBASE databases and the major search terms were SLE, PLE, IPO, hepatitis and pancreatitis. A total of 125 articles were chosen for our study. SLE-related PLE was characterized by edema and hypoalbuminemia, with Technetium 99m labeled human albumin scintigraphy ( 99m Tc HAS) and alpha-1-antitrypsin fecal clearance test commonly used as diagnostic test. The most common site of protein leakage was the small intestine and the least common site was the stomach. More than half of SLE-related IPO patients had ureterohydronephrosis, and sometimes they manifested as interstitial cystitis and hepatobiliary dilatation. Lupus hepatitis and SLE accompanied by autoimmune hepatitis (SLE-AIH overlap) shared similar clinical manifestations but had different autoantibodies and histopathological features, and positive anti-ribosome P antibody highly indicated the diagnosis of lupus hepatitis. Lupus pancreatitis was usually accompanied by high SLE activity with a relatively high mortality rate. Early diagnosis and timely intervention were crucial, and administration of corticosteroids and immunosuppressants was effective for most of the patients.

    To determine the type, frequency and cause of the most frequent hostile behaviors in a sample of nurses in the Balearic Islands and the socio-professional variables involved. We performed a cross-sectional descriptive study. The sample was composed of 464 members of the association of nurses of the Balearic Islands (392 women and 49 men). Age ranged from 25 to 65 years (mean: 35.11; SD: 9.62); 368 worked in public institutions and 71 in private centers. The instrument used was the Psychological Mobbing Questionnaire. A total of 17.2% of the nurses believed they had experienced mobbing at work (men: 22.4%; women: 14.5%). Significant differences were found according to age, but not according to institution. The most frequent hostile behavior was related to distortion of information, criticism of the purported victim, and lack of professional consideration. The perpetrators of mobbing were mainly, and very significantly, the bosses. According to these results, one in five nurses in the Balearic Islands has experienced mobbing in the workplace. However, because of the low response rate, caution should be exercised when generalizing these results. Nevertheless, health institutions should bear these findings in mind to ensure standards of behavior that do not jeopardize workers' health and dignity.

    Purpose: To evaluate cranial findings in patients with neurologically symptomatic sickle cell disease (SCD). Materials and methods: We studied 50 consecutive patients with SCD and neurologic symptoms. All patients underwent brain MR examinations: all 50 underwent classic MR imaging; 42, diffusion-weighted MR imaging; 10, MR angiography; four, MR venography; and three patients, digital subtraction angiography. Results: Of the 50 SCD patients, 19 (38%) had normal MR findings, and 31 (62%) showed abnormalities on brain MR images. Of the 50 patients, 16 (32%) had ischemic lesions; two (4%), subarachnoid hemorrhage; one (2%), moya-moya pattern; one (2%), posterior reversible encephalopathy; one (2%), dural venous sinus thrombosis; 12 (24%), low marrow signal intensity and thickness of the diploic space; 12 (24%), cerebral atrophy; and two (4%), osteomyelitis. Twenty-seven patients (54%) presented with headache, which was the most common clinical finding. Conclusions: The cranial involvement is one of the most devastating complications of SCD. Early and accurate diagnosis is important in the management of cranial complications of SCD.

    The study focuses on incidents at Department of Energy (DOE) facilities involving the migration of radioactive contaminants through protective clothing. The authors analyzed 68 occurrence reports for the following factors: (1) type of work; (2) working conditions; (3) type of anti-contamination (anti-C) material; (4) area of body or clothing contaminated; and (5) nature of spread of contamination. A majority of reports identified strenuous work activities such as maintenance, construction, or decontamination and decommissioning (D ampersand D) projects. The reports also indicated adverse working conditions that included hot and humid or cramped work environments. The type of anti-C clothing most often identified was cotton or water-resistant, disposable clothing. Most of the reports also indicated contaminants migrating through perspiration-soaked areas, typically in the knees and forearms. On the basis of their survey, the authors recommend the use of improved engineering controls and resilient, breathable, waterproof protective clothing for work in hot, humid, or damp areas where the possibility of prolonged contact with contamination cannot be easily avoided or controlled

    The pathological characteristics of atherosclerosis (AS) include lipid accumulation, fibrosis formation and atherosclerotic plaque produced in artery intima, which leads to vascular sclerosis, lumen stenosis and irritates the ischemic changes of corresponding organs. Endothelial dysfunction was closely associated with AS. Nitric oxide (NO) is a multifunctional signaling molecule involved in the maintenance of metabolic and cardiovascular homeostasis. NO is also a potent endogenous vasodilator and enters for the key processes that suppresses the formation vascular lesion even AS. NO bioavailability indicates the production and utilization of endothelial NO in organisms, its decrease is related to oxidative stress, lipid infiltration, the expressions of some inflammatory factors and the alteration of vascular tone, which plays an important role in endothelial dysfunction. The enhancement of arginase activity and the increase in asymmetric dimethylarginine and hyperhomocysteinemia levels all contribute to AS by intervening NO bioavailability in human beings. Diabetes mellitus, obesity, chronic kidney disease and smoking, etc., also participate in AS by influencing NO bioavailability and NO level. Here, we reviewed the relationship between NO bioavailability and AS according the newest literatures. Copyright © 2017. Published by Elsevier Masson SAS.

    This study examines one of the instructional practices features utilized within the Year 8 mathematics lessons in Brunei Darussalam. The codes from the TIMSS 1999 Video Study were applied and strictly followed, and from the 183 mathematics problems recorded, there were 95 problems with a solution presented during the public segments of the video-recorded lesson sequences of the four sampled teachers. The analyses involved firstly, identifying the processes related to mathematical problem statements, and secondly, examining the different processes used in solving the mathematical problems for each problem publicly completed during the lessons. The findings revealed that for three of the teachers, their problem statements coded as `using procedures' ranged from 64% to 83%, while the remaining teacher had 40% of his problem statements coded as `making connections.' The processes used when solving the problems were mainly `using procedures', and none of the problems were coded as `giving results only'. Furthermore, all four teachers made use of making the relevant connections in solving the problems given to their respective students.

  1. Uncertainties Involved in the Iopospheric Conductivity Estimation

    2002-12-01

    Full Text Available Various uncertainties involved in ionospheric conductivity estimation utilizing the electron density profile obtained from the Sondrestrom incoherent scatter radar are examined. First, we compare the conductivity which is based on raw electron density and the one based on corrected electron density that takes into account the effects of the difference between the electron and ion temperatures and the Debye length. The corrected electron density yields higher Pedersen and Hall conductivities than the raw electron density does. Second, the dependence of collision frequency model on the conductivity estimation is examined. Below 110 km conductivity does not depend significantly on collision frequency models. Above 110 km, however, the collision models affect the conductivity estimation. Third, the influence of the electron and ion temperatures on the conductivity estimation is examined. Electron and ion temperatures carrying an error of about 10% do not seem to affect significantly the conductivity estimation. Fourth, also examined is the effect of the choice of the altitude range of integration in calculating the height-integrated conductivity, conductance. It has been demonstrated that the lower and upper boundaries of the integration are quite sensitive to the estimation of the Hall and Pedersen conductances, respectively.

    2009-07-13

    Extracellular polymeric substances (EPS) produced by microorganisms are a complex mixture of biopolymers primarily consisting of polysaccharides, as well as proteins, nucleic acids, lipids and humic substances. EPS make up the intercellular space of microbial aggregates and form the structure and architecture of the biofilm matrix. The key functions of EPS comprise the mediation of the initial attachment of cells to different substrata and protection against environmental stress and dehydration. The aim of this review is to present a summary of the current status of the research into the role of EPS in bacterial attachment followed by biofilm formation. The latter has a profound impact on an array of biomedical, biotechnology and industrial fields including pharmaceutical and surgical applications, food engineering, bioremediation and biohydrometallurgy. The diverse structural variations of EPS produced by bacteria of different taxonomic lineages, together with examples of biotechnological applications, are discussed. Finally, a range of novel techniques that can be used in studies involving biofilm-specific polysaccharides is discussed.

  3. SWEDISH CRIME FICTION AS SOCIALLY INVOLVED LITERATURE

    2011-01-01

    Full Text Available Swedish crime novel has been transforming for many years to become more socially involved. The ambition of many writers is not only to entertain the readers but also to participating in the social debate, criticizing the political and economical system, focusing on important issues such as violence against women, exploitation of working class by the privileged ruling class, the problems of a modern family and the situation of immigrants. Since the moment when in the mid 60’s two journalists Maj Sjöwall and Per Wahlöö decided to use popular literature to spread social matters many other Swedish writers have decided to follow their way. Some of them are journalists – like Liza Marklund, Börge Hellström and Anders Roslund or Stieg Larsson. Their novels as well as the ones written by Henning Mannkel on Kurt Wallander have become crucial evidence of changes of Swedish society in the past twenty years. Modern Swedish crime fiction illustrates the population in the model fashion that is the reason why it can become one of the interests of the sociology of literature.

    Renal involvement in antiphospholipid syndrome (APS), either primary or systemic lupus erythematosus (SLE)-related APS, includes renal artery stenosis or thrombosis, renal infarction, renal vein thrombosis and a small-vessel vaso-occlusive nephropathy defined as "antiphospholipid antibody (aPL)-associated nephropathy." aPL-associated nephropathy is characterized by acute lesions, thrombotic microangiopathy, and chronic lesions such as fibrous intimal hyperplasia, organizing thrombi with or without recanalization, fibrous occlusions of arteries or arterioles and focal cortical atrophy. Systemic hypertension, hematuria, proteinuria (ranging from mild to nephrotic level) and renal insufficiency represent the major clinical manifestations associated with aPL-associated nephropathy. Similar renal histologic and clinical characteristics have been described among all different groups of patients with positive aPL (primary APS, SLE-related APS, catastrophic APS and SLE/non-APS with positive aPL). In patients with aPL-associated nephropathy lesions in the absence of other causes associated with similar histological characteristics, aPL testing needs to be considered. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available Cytomegalovirus (CMV is the most common cause of congenital viral infection, affecting 0.2 to 2.3% of all live births in developed countries. Very low birth weight and extremely low birth weight newborns are at higher risk of symptomatic CMV infection, most commonly secondary and acquired through breast milk. Gastrointestinal involvement is rare in acquired CMV infections, but it could be an important manifestation of postnatal infection in preterm infants admitted to neonatal intensive care units. Early onset of CMV gastrointestinal signs/symptoms is very rare. In a review of the literature it is described in 5 newborns in the first 24 hours of life, and 6 considering the onset in the first week of life. This review describes also a case report of congenital CMV in an immunocompetent newborn with onset of gastrointestinal signs immediately after birth: a possible association between viral infection and enteric manifestations was considered in the differential diagnosis. A review of the literature of the different case reports found has done, with description and comparison of the different patients and clinical presentations.

    Almost all extant plant species have spontaneously doubled their genomes at least once in their evolutionary histories, resulting in polyploidy which provided a rich genomic resource for evolutionary processes. Moreover, superior polyploid clones have been created during the process of crop domestication. Polyploid plants generated by evolutionary processes and/or crop domestication have been the intentional or serendipitous focus of research dealing with the dynamics and consequences of genome evolution. One of the new trends in genomics research is to create synthetic polyploid plants which provide materials for studying the initial genomic changes/responses immediately after polyploid formation. Polyploid plants are also used in functional genomics research to study gene expression in a complex genomic background. In this review, we summarize the recent progress in genomics research involving ancient, young, and synthetic polyploid plants, with a focus on genome size evolution, genomics diversity, genomic rearrangement, genetic and epigenetic changes in duplicated genes, gene discovery, and comparative genomics. Implications on plant sciences including evolution, functional genomics, and plant breeding are presented. It is anticipated that polyploids will be a regular subject of genomics research in the foreseeable future as the rapid advances in DNA sequencing technology create unprecedented opportunities for discovering and monitoring genomic and transcriptomic changes in polyploid plants. The fast accumulation of knowledge on polyploid formation, maintenance, and divergence at whole-genome and subgenome levels will not only help plant biologists understand how plants have evolved and diversified, but also assist plant breeders in designing new strategies for crop improvement.

  7. Genes involved in cell division in mycoplasmas

    2007-01-01

    Full Text Available Bacterial cell division has been studied mainly in model systems such as Escherichia coli and Bacillus subtilis, where it is described as a complex process with the participation of a group of proteins which assemble into a multiprotein complex called the septal ring. Mycoplasmas are cell wall-less bacteria presenting a reduced genome. Thus, it was important to compare their genomes to analyze putative genes involved in cell division processes. The division and cell wall (dcw cluster, which in E. coli and B. subtilis is composed of 16 and 17 genes, respectively, is represented by only three to four genes in mycoplasmas. Even the most conserved protein, FtsZ, is not present in all mycoplasma genomes analyzed so far. A model for the FtsZ protein from Mycoplasma hyopneumoniae and Mycoplasma synoviae has been constructed. The conserved residues, essential for GTP/GDP binding, are present in FtsZ from both species. A strong conservation of hydrophobic amino acid patterns is observed, and is probably necessary for the structural stability of the protein when active. M. synoviae FtsZ presents an extended amino acid sequence at the C-terminal portion of the protein, which may participate in interactions with other still unknown proteins crucial for the cell division process.

    2011-03-01

    Digital Imaging and Communications in Medicine (DICOM) is a standard for handling, storing, printing, and transmitting information in medical imaging. XML (Extensible Markup Language) is a set of rules for encoding documents in machine-readable form which has become more and more popular. The combination of these two is very necessary and promising. Using XML tags instead of numeric labels in DICOM files will effectively increase the readability and enhance the clear hierarchical structure of DICOM files. However, due to the fact that the XML tags rely heavily on the orders of the tags, the strong data dependency has a lot of influence on the flexibility of inserting and exchanging data. In order to improve the extensibility and sharing of DICOM files, this paper introduces XML Path-Tag to DICOM. When a DICOM file is converted to XML format, adding simple Path-Tag into the DICOM file in place of complex tags will keep the flexibility of a DICOM file while inserting data elements and give full play to the advantages of the structure and readability of an XML file. Our method can solve the weak readability problem of DICOM files and the tedious work of inserting data into an XML file. In addition, we set up a conversion engine that can transform among traditional DICOM files, XML-DCM and XML-DCM files involving XML Path-Tag efficiently.

    Full Text Available BACKGROUND Diphtheria still endemic in many developing countries and is responsible for high case fatality. Myocardial involvement is a serious complication of diphtheria and diphtheria myocarditis frequently complicated by arrhythmias causes sudden death if not managed properly. So, early and adequate administration of Anti-Diphtheritic Serum (ADS and frequent monitoring particularly 24 hrs. ECG monitoring is helpful to detect any serious cardiac arrhythmias. METHODS A prospective study on patients who were culture positive diagnosed on the basis of WHO definition were treated and analysed in respect to homographic details, immunisation strategy, and clinical features with particular attention to myocarditis. RESULTS In the study, common age group affected by diphtheria was 5 to 10 years. Incidence of myocarditis more in same age group. Out of 64 patients with myocarditis, 23 patients died. CONCLUSION Incidence of diphtheria has increased in the recent years. Commonly effected age group is 5 to 10 years and most of them are presented with asymptomatic myocarditis. Symptomatic diphtheritic myocarditis has high mortality rate even with aggressive management. Patient who presented with either LBBB alone are with combination of other conduction of abnormalities has high mortality rate.

    2006-07-01

    Genetic and lifestyle-related risk factors for Alzheimer disease (AD) are associated with an increase in oxidative stress, suggesting that oxidative stress is involved at an early stage of the pathologic cascade. Moreover, oxidative stress is mechanistically and chronologically associated with other key features of AD, namely, metabolic, mitochondrial, metal, and cell-cycle abnormalities. Contrary to the commonly held notion that pathologic hallmarks of AD signify etiology, several lines of evidence now indicate that aggregation of amyloid-beta and tau is a compensatory response to underlying oxidative stress. Therefore, removal of proteinaceous accumulations may treat the epiphenomenon rather than the disease and may actually enhance oxidative damage. Although some antioxidants have been shown to reduce the incidence of AD, the magnitude of the effect may be modified by individual factors such as genetic predisposition (e.g. apolipoprotein E genotype) and habitual behaviors. Because caloric restriction, exercise, and intellectual activity have been experimentally shown to promote neuronal survival through enhancement of endogenous antioxidant defenses, a combination of dietary regimen of low total calorie and rich antioxidant nutrients and maintaining physical and intellectual activities may ultimately prove to be one of the most efficacious strategies for AD prevention.

    This study analyzes the involvement of men in abortion in Vietnam, where induced abortion is legal and abortion rates are among the highest in the world. Twenty men were interviewed in 1996 about the role they played in their wives' abortions and about their feelings and ethical views concerning the procedure. The results showed that both husbands and wives considered the husband to be the main decisionmaker regarding family size, which included the decision to have an abortion, but that, in fact, some women had undergone an abortion without consulting their husbands in advance. Parents and in-laws were usually not consulted; the couples thought they might object to the decision on moral grounds. Respondents' ethical perspectives on abortion are discussed. When faced with an unwanted pregnancy, the husbands adopted an ethics of care and responsibility toward family and children, although some felt that abortion was immoral. The study highlights the importance of understanding husbands' perspectives on their responsibilities and rights in reproductive decisionmaking and their ethical and other concerns related to abortion.

    2013-06-01

    Filicide-suicide, or murder of a child by a parent followed by suicide, has an unknown incidence in both the general and disabled population. As there is no national database, the authors examined known associated factors and newspaper reports to characterize filicide-suicide victims and perpetrators involving children with disabilities. A newspaper search was conducted using LexisNexis and NewsBank: Access World News databases through the University of California, Irvine Library's Web site. Age, gender of child and parent, method used, and diagnoses of parent and child were recorded. Twenty-two news articles were found describing a total of 26 disabled children as victims of filicide-suicide between 1982 and 2010. Eighty-one percent of children killed were male, and 54% were autistic. Thirty percent of perpetrators had a reported mental illness. Male children or children with autism may be at risk for filicide-suicide, but accurate record keeping is needed to determine the incidence and risk factors and aid in its prevention in the disabled population.

    1995-01-01

    Local public opposition to federal bureaucratic decisions has resulted in public agencies rethinking the role of stakeholders in decision making. Efforts to include stakeholders directly in the decision-making process are on the increase. Unfortunately, many attempts to involve members of the public in decisions involving complex technical issues have failed. A key problem has been defining a meaningful role for the public in the process of arriving at a technical decision. This paper describes a successful effort by Sandia National Laboratories (SNL) in New Mexico to involve stakeholders in an important technical decision associated with its Environmental Restoration (ER) Project. The decision was where to locate a Corrective Action Management Unit (CAMU), a facility intended to consolidate and store wastes generated from the cleanup of hazardous waste sites. A formal priority setting process known as the Laboratory Integration Prioritization System (LIPS) was adapted to provide an approach for involving the public. Although rarely applied to stakeholder participation, the LIPS process proved surprisingly effective. It produced a consensus over a selected site and enhanced public trust and understanding of Project activities

    Full Text Available This paper investigates consumer involvement profile among people who intend to purchase mobile devises. The study considers the effects of various factors influencing on purchase intention including consumers’ personal characteristics such as age, gender, income as well as some external factors including advertisement. The study uses a questionnaire in Likert scale, originally developed by O’Cass (2000 [O’Cass, A. (2000. An assessment of consumers' product, purchase decision, advertising and consumption involvement in fashion clothing. Journal of Economic Psychology, 21, 545-576.]. The questionnaire has been distributed among 385 people, randomly who purchased mobile devices from a mall in city of Tehran, Iran. Using Pearson correlation test, the study has concluded that oral advertisement as well as consumer purchase involvement have positive and strong relationship with consumer’s purchase intention. In terms of age, people aged 20-30 maintained the highest purchase intention. In addition, in terms of gender, men had more purchase involvement than women did.

    2010-03-01

    Full Text Available Abstract Background Bacteria in periodontal pockets develop complex sessile communities that attach to the tooth surface. These highly dynamic microfloral environments challenge both clinicians and researchers alike. The exploration of structural organisation and bacterial interactions within these biofilms is critically important for a thorough understanding of periodontal disease. In recent years, Filifactor alocis, a fastidious, Gram-positive, obligately anaerobic rod was repeatedly identified in periodontal lesions using DNA-based methods. It has been suggested to be a marker for periodontal deterioration. The present study investigated the epidemiology of F. alocis in periodontal pockets and analysed the spatial arrangement and architectural role of the organism in in vivo grown subgingival biofilms. Results A species-specific oligonucleotide probe, FIAL, was designed and evaluated. A total of 490 subgingival plaque samples were submitted to PCR and subsequent dot blot hybridization to compare the prevalence of F. alocis in patients suffering from generalized aggressive periodontitis (GAP, chronic periodontitis (CP, and control subjects resistant to periodontitis. Moreover, a specially designed carrier system was used to collect in vivo grown subgingival biofilms from GAP patients. Subsequent topographic analysis was performed using fluorescence in situ hybridization. While the majority of patients suffering from GAP or CP harboured F. alocis, it was rarely detected in the control group. In the examined carrier-borne biofilms the organism predominantly colonized apical parts of the pocket in close proximity to the soft tissues and was involved in numerous structures that constitute characteristic architectural features of subgingival periodontal biofilms. Conclusions F. alocis is likely to make a relevant contribution to the pathogenetic structure of biofilms accounting for periodontal inflammation and can be considered an excellent marker

    Costello syndrome (CS) is a multisystem disorder caused by heterozygous germline mutations in the HRAS proto-oncogene. Respiratory system complications have been reported in individuals with CS, but a comprehensive description of the full spectrum and incidence of respiratory symptoms in these patients is not available. Here, we report the clinical course of four CS patients with respiratory complications as a major cause of morbidity. Review of the literature identified 56 CS patients with descriptions of their neonatal course and 17 patients in childhood/adulthood. We found that in the neonatal period, respiratory complications are seen in approximately 78% of patients with transient respiratory distress reported in 45% of neonates. Other more specific respiratory diagnoses were reported in 62% of patients, the majority of which comprised disorders of the upper and lower respiratory tract. Symptoms of upper airway obstruction were reported in CS neonates but were more commonly diagnosed in childhood/adulthood (71%). Analysis of HRAS mutations and their respiratory phenotype revealed that the common p.Gly12Ser mutation is more often associated with transient respiratory distress and other respiratory diagnoses. Respiratory failure and dependence on mechanical ventilation occurs almost exclusively with rare mutations. In cases of prenatally diagnosed CS, the high incidence of respiratory complications in the neonatal period should prompt anticipatory guidance and development of a postnatal management plan. This may be important in cases involving rarer mutations. Furthermore, the high frequency of airway obstruction in CS patients suggests that otorhinolaryngological evaluation and sleep studies should be considered. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

  20. Immune Responses Involved in Mycobacterium Tuberculosis Infection

    Full Text Available Background and Objectives: Mycobacterium tuberculosis is the causative agent of tuberculosis (TB. Approximately one-third of the world's population is infected with M. tuberculosis. Despite the availability of drug and vaccine, it remains one of the leading causes of death in humans especially in developing countries. Epidemiological studies have indicated that only 10-30% of people exposed to tubercle bacillus are infected with M. tuberculosis, and at least 90% of the infected people finally do not acquire TB. The studies have indicated that the host efficient immune system has essential roles in the control of TB infection such that the highest rate of mortality and morbidity is seen in immunocompromised patients such as people infected with HIV. M. tuberculosis is an obligatory intracellular bacterium. It enters the body mainly through the respiratory tract and alveolar macrophages combat this pathogen most commonly. In addition to alveolar macrophages, various T-cell subpopulations need to be activated to overcome this bacterium's resistance to the host defense systems. CD4+ T cells, through production of several cytokines such as IFN-γ and TNF-α, and CD8+ T cells, through cytotoxic activities and induction of apoptosis in infected cells, play critical roles in inducing appropriate immune responses against M. tuberculosis. Although cell-mediated immunity is the cornerstone of host responses against TB and the recent studies have provided evidence for the importance of humoral and innate immune system in the control of TB, a profound understanding of the immune responses would provide a basis for development of new generations of vaccines and drugs. The present study addresses immune responses involved in M. tuberculosis infection.

  1. Lateral Habenula Involvement in Impulsive Cocaine Seeking.

    The lateral habenula (LHb) is a brain structure receiving inputs from limbic forebrain areas and innervating major midbrain monoaminergic nuclei. Evidence indicates LHb involvement in sleep control, reward-based decision making, avoidance of punishment, and responses to stress. Additional work has established that the LHb mediates negative feedback in response to aversive events. As a hallmark of drug addiction is the inability to limit drug use despite negative consequences, we hypothesize that LHb dysfunction may have a role in the lack of control over drug seeking. Here we examine the effects of LHb inactivation in control over drug seeking in several cocaine self-administration (SA) paradigms in rats. We find that inhibition of the LHb with GABAergic agonists did not alter cocaine SA under progressive ratio or seeking/taking chained reinforcement schedules, or during punishment-induced suppression of cocaine-reinforced responding. In contrast, LHb inhibition increased cocaine seeking when the drug was not available in rats trained to discriminate its presence using an environmental cue. This effect of LHb inhibition was selective for cocaine, as it did not impair responding for sucrose reinforcement. The effect of LHb injection of GABA agonists was mimicked by intra-LHb muscarinic cholinergic (mACh) antagonist injection, and activation of mACh receptors excited a majority of LHb neurons in in vitro electrophysiology experiments. These results indicate that the LHb participates in the suppression of impulsive responding for cocaine through the activation of a cholinergic circuit, and they suggest that LHb dysfunction may contribute to impaired impulse control associated with drug addiction.

  2. Public involvement in radioactive waste management decisions

    1994-04-01

    Current repository siting efforts focus on Yucca Mountain, Nevada, where DOE`s Office of Civilian Radioactive Waste Management (OCRWM) is conducting exploratory studies to determine if the site is suitable. The state of Nevada has resisted these efforts: it has denied permits, brought suit against DOE, and publicly denounced the federal government`s decision to study Yucca Mountain. The state`s opposition reflects public opinion in Nevada, and has considerably slowed DOE`s progress in studying the site. The Yucca Mountain controversy demonstrates the importance of understanding public attitudes and their potential influence as DOE develops a program to manage radioactive waste. The strength and nature of Nevada`s opposition -- its ability to thwart if not outright derail DOE`s activities -- indicate a need to develop alternative methods for making decisions that affect the public. This report analyzes public participation as a key component of this openness, one that provides a means of garnering acceptance of, or reducing public opposition to, DOE`s radioactive waste management activities, including facility siting and transportation. The first section, Public Perceptions: Attitudes, Trust, and Theory, reviews the risk-perception literature to identify how the public perceives the risks associated with radioactivity. DOE and the Public discusses DOE`s low level of credibility among the general public as the product, in part, of the department`s past actions. This section looks at the three components of the radioactive waste management program -- disposal, storage, and transportation -- and the different ways DOE has approached the problem of public confidence in each case. Midwestern Radioactive Waste Management Histories focuses on selected Midwestern facility-siting and transportation activities involving radioactive materials.

    Full Text Available Objective: Tuberous sclerosis complex (TSC is a multisystem autosomal dominant disease characterized by the development of benign neoplasia in skin, brain and kidneys. There are three particular renal disorders in TSC including renal cysts, renal angiomyolipoma and renal cell carcinoma. In the current study we aimed to investigate renal findings of TSC patients followed in our clinic. Methods: Patients’ family history, convulsion history, age, gender, physical examination findings, renal function tests, ultrasound and/or magnetic resonance imaging, results of computerized tomography, echocardiography and eye findings were found from hospital records and evaluated. Tuberous sclerosis diagnosis was made by clinical and imaging findings in 19 patients. Results: Nineteen cases were included in study. Eleven was males and the remaining 8 were females. The mean age was 75.5±65, 1 month (3 month- 18 year and follow up time was 14.6±7 month. Renal angiomyolipoma was the most commonly seen pathology alone (4 patients-21% and with renal cysts (5 patients-26.3%. Autosomal dominant polycystic kidney disease was with TSC in two patients. Four patients were presented with only simple renal cysts. Two patients had increased renal echogenicity and one patient had mild pelvicaliectasis. Ureteropelvic junction obstruction, urinary tract infection, nephrolithiasis and hemorrhages are commonly seen complications in TSC. Five patients had history of urinary tract infection. None of the patients had bleeding or rupture complication. Hypertension and end stage renal disease were not seen. Conclusion: The most commonly seen renal lesions in TSC are angiomyolipomas and kidney cysts. At the time of TSC diagnosis, all the children must be screened for renal involvement and we should remember renal findings can change with time and new findings can be added to old ones. Therefore nephrologist follow up has been done in all patients.

    We present the case histories, autopsy findings and toxicology findings of two fatal intoxications involving the designer drug, butyryl fentanyl. The quantitative analysis of butyryl fentanyl in postmortem fluids and tissues was performed by an ultrahigh-performance liquid chromatography tandem mass spectrometry method. In the first case, butyryl fentanyl was the only drug detected with concentrations of 99 ng/mL in peripheral blood, 220 ng/mL in heart blood, 32 ng/mL in vitreous humor, 590 ng/mL in gastric contents, 93 ng/g in brain, 41 ng/g in liver, 260 ng/mL in bile and 64 ng/mL in urine. The cause of death was ruled fatal intoxication by butyryl fentanyl. In the second case, butyryl fentanyl was detected along with acetyl fentanyl, alprazolam and ethanol. The butyryl fentanyl concentrations were 3.7 ng/mL in peripheral blood, 9.2 ng/mL in heart blood, 9.8 ng/mL in vitreous humor, 4,000 ng/mL in gastric contents, 63 ng/g in brain, 39 ng/g in liver, 49 ng/mL in bile and 2 ng/mL in urine. The acetyl fentanyl concentrations were 21 ng/mL in peripheral blood, 95 ng/mL in heart blood, 68 ng/mL in vitreous humor, 28,000 ng/mL in gastric contents, 200 ng/g in brain, 160 ng/g in liver, 330 ng/mL in bile and 8 ng/mL in urine. In addition, the alprazolam concentration was 40 ng/mL and the ethanol concentration was 0.11 g/dL, both measured in peripheral blood. The cause of death in the second case was ruled a mixed drug intoxication. In both cases, the manner of death was accident. PMID:27339481

    Research examining factors that predict youth's involvement in organized activities is very limited, despite associations with positive outcomes. Using data from 1043 youth (49% female; 46.4% Hispanic, 35.4% African American, 14.0% Caucasian, and 4.2% other) from the Project on Human Development in Chicago Neighborhoods, this study examined how characteristics of parents (supervision, warmth) and neighborhoods (perceived neighborhood safety and collective efficacy) predict patterns of adolescents' involvement in organized activities concurrently (i.e., intensity) and longitudinally (i.e., type and breadth). Parental supervision predicted adolescents' participation in organized activities across multiple waves. Neighborhood violence was positively associated with concurrent participation in organized activities after controlling for socioeconomic status (SES), whereas higher neighborhood collective efficacy predicted greater breadth in organized activity participation across time. These findings have important implications regarding how to attract and sustain organized activity participation for low-income, urban youth.

    Current models of adolescent drinking behavior hypothesize that alcohol expectancies mediate the effects of other proximal and distal risk factors. This longitudinal study tested the hypothesis that the effects of parental alcohol involvement on their children's drinking behavior in mid-adolescence are mediated by the children's alcohol expectancies in early adolescence. A sample of 148 initially 9-11 year old boys and their parents from a high-risk population and a contrast group of community families completed measures of drinking behavior and alcohol expectancies over a 6-year interval. We analyzed data from middle childhood (M age = 10.4 years), early adolescence (M age = 13.5 years), and mid-adolescence (M age = 16.5 years). The sample was restricted only to adolescents who had begun to drink by mid-adolescence. Results from zero-inflated Poisson regression analyses showed that 1) maternal drinking during their children's middle childhood predicted number of drinking days in middle adolescence; 2) negative and positive alcohol expectancies in early adolescence predicted odds of any intoxication in middle adolescence; and 3) paternal alcoholism during their children's middle childhood and adolescents' alcohol expectancies in early adolescence predicted frequency of intoxication in middle adolescence. Contrary to predictions, child alcohol expectancies did not mediate the effects of parental alcohol involvement in this high-risk sample. Different aspects of parental alcohol involvement, along with early adolescent alcohol expectancies, independently predicted adolescent drinking behavior in middle adolescence. Alternative pathways for the influence of maternal and paternal alcohol involvement and implications for expectancy models of adolescent drinking behavior were discussed.

    To investigate how South Asian patients conceptualise the notion of clinical trials and to identify key processes that impact on trial participation and the extent to which communication difficulties, perceptions of risk and attitudes to authority influence these decisions. Also to identify whether 'South Asian' patients are homogeneous in these issues, and which factors differ between different South Asian subgroups and finally how professionals regard the involvement of South Asian patients and their views on strategies to increase participation. A review of the literature on minority ethnic participation in clinical trials was followed by three qualitative interview studies. Interviews were taped and transcribed (and translated if required) and subjected to framework analysis. Face-to-face interviews were conducted with 25 health professionals; 60 South Asian lay people who had not taken part in a trial and 15 South Asian trial participants. Motivations for trial participation were identified as follows: to help society, to improve own health or that of family and friends, out of obligation to the doctor and to increase scientific knowledge. Deterrents were concerns about drug side-effects, busy lifestyles, language, previous bad experiences, mistrust and feelings of not belonging to British society. There was no evidence of antipathy amongst South Asians to the concept of clinical trials and, overall, the younger respondents were more knowledgeable than the older ones. Problems are more likely to be associated with service delivery. Lack of being approached was a common response. Lay-reported factors that might affect South Asian participation in clinical trials include age, language, social class, feeling of not belonging/mistrust, culture and religion. Awareness of clinical trials varied between each group. There are more similarities than differences in attitudes towards clinical trial participation between the South Asian and the general population

  16. Bioethical Principles of Biomedical Research Involving Animals

    Full Text Available A major requirement both of national and international ethical codes for human experimentation, and of national legislation in many cases, is that new substances or devices should not be used for the first time on human beings unless previous tests on animals have provided a reasonable presumption of their safety. That is so called: Good Clinical Praxis (GCP. There are two international ethical codes intended principally for the guidance of countries or institutions that have not yet formulated their own ethical requirements for human experimentation: The Declaration of Helsinki of the World Medical Association and The Proposed International Guidelines for Biomedical Research Involving Human Subjects of the Council for International Organizations of Medical Sciences and the World Health Organization[1].Animal experimentation is fundamental to the biomedical sciences, not only for the advancement of specific vital processes, but also for the improvement of methods of prevention, diagnosis, and treatment of disease both in man and in animals. The use of animals is also indispensable for testing the potency and safety of biological substances used in human and veterinary medicine, as well as for determining the toxicity of the rapidly growing number of molecules that never existed before in nature and which may represent a hazard to health. This extensive exploitation by man of animals implies philosophical and moral problems that are not peculiar to their use for scientific purposes, and there are no objective ethical criteria by which to judge claims and counterclaims in such matters[2]. However, there is a consensus that „deliberate cruelty is repugnant”.While many countries have general laws or regulations imposing penalties for ill-treatment of animals, relatively few make specific provision for their use for scientific purposes. Because of differing legal systems and cultural backgrounds there are varying approaches to the use of

    To examine the relationship of paternal involvement in diabetes care with adherence and glycemic control. One hundred and thirty-six mothers and fathers of preadolescents (aged 9-12 years) with type 1 diabetes reported on paternal involvement. Adherence was measured by interview and blood glucose meter downloads. Mothers' and fathers' ratings of paternal involvement in diabetes care were compared. We evaluated three structural equation models linking paternal involvement with adherence and glycemic control. Mothers and fathers reported similar amounts of paternal involvement, yet mothers rated paternal involvement as more helpful. The data supported a model indicating links between more paternal involvement and higher HbA1c and between lower adherence and higher HbA1c. Mediation and moderation models were not supported. Although paternal involvement was not directly associated with treatment adherence, it was associated with poorer glycemic control. Some fathers may increase their involvement in response to suboptimal glycemic outcomes.

    1997-01-01

    Researchers have reported contradictory relations between job involvement and well-being. In this study, a differentiation was made between job involvement based on need congruence and the resulting need fulfillment in one's job and job involvement not based on this concept. Participants were 383 women and 50 men. Job involvement based on need congruence was related to a high level of well-being or was negatively related to it. The mean levels of the two kinds of involvement were equal. Results suggest that job involvement is related to well-being only if the constructs are based on equal processes-that is, on need congruence in one's job.

    Although myriad studies document the benefits of parental involvement in education on various indicators of children's academic performance, less research examines parental involvement among adolescents in low-income Latino families. Incorporating a multidimensional conceptualization of parental involvement, this study examined the relation between parental involvement and academic outcomes in a sample of 223 low-income, Latino adolescents. Results indicated that three types of parental involvement (gift/sacrifice, future discussions/academic socialization, and school involvement) had significant, positive associations with academic outcomes. Moreover, our results suggest that parents' stories about struggles with poverty and immigration are an important component of parental involvement, contributing to adolescents' desire to succeed academically and "give back" to parents. Additionally, our findings indicated that the positive relations between parental involvement and academic outcomes were stronger for immigrant youth and for those with higher endorsements of the Latino cultural value of respeto (respect).

    To investigate fathers' involvement with their children using an ecological model, multiple respondents, and a comprehensive definition of fathers' involvement. The study's primary objectives were: (a) to describe the characteristics of fathers whose infants are born to low-income, urban, African-American adolescent mothers; (b) to describe the ways in which fathers are involved with their children; and (c) to identify factors associated with fathers' involvement. A total of 181 first-time mothers (aged parenting. Mothers provided the name of their infant's father; 109 (60%) of the fathers also agreed to participate. Baseline interviews of mothers, fathers, and grandmothers addressed demographic characteristics, relationships, and the father's involvement with his child. Three multivariate regression models were used to identify factors associated with paternal involvement, explaining 35% to 51% of the variability in father involvement. Regardless of the respondent (mother, father, or grandmother), paternal involvement was predicted most strongly by the quality of the parents' romantic relationship. The father's employment status, the maternal grandmother's education, and the father's relationship with the baby's maternal grandmother were also associated with paternal involvement. The study confirmed the value of an ecological perspective that uses multiple informants and a comprehensive definition of father involvement that includes multiple role functions. Efforts to increase paternal involvement should help young parents separate the father's relationship with their child from the romantic relationship between the mother and father, address the roles played by maternal grandmothers, and assist fathers to complete their education, and obtain and keep jobs.

    2013-12-01

    The Institute of Medicine recently recommended that comparative effectiveness research (CER) should involve input from consumers. While systematic reviews are a major component of CER, little is known about consumer involvement. To explore current approaches to involving consumers in US-based and key international organizations and groups conducting or commissioning systematic reviews ('organizations'). In-depth, semi-structured interviews with key informants and review of organizations' websites. Seventeen highly regarded US-based and international (Cochrane Collaboration, Campbell Collaboration) organizations. Organizations that usually involve consumers (seven of 17 in our sample) involve them at a programmatic level in the organization or in individual reviews through one-time consultation or on-going collaboration. For example, consumers may suggest topics, provide input on the key questions of the review, provide comments on draft protocols and reports, serve as co-authors or on an advisory group. Organizations involve different types of consumers (individual patients, consumer advocates, families and caregivers), recruiting them mainly through patient organizations and consumer networks. Some offer training in research methods, and one developed training for researchers on how to involve consumers. Little formal evaluation of the effects of consumer involvement is being carried out. Consumers are currently involved in systematic reviews in a variety of ways and for various reasons. Assessing which approaches are most effective in achieving different aims of consumer involvement is now required to inform future recommendations on consumer involvement in CER. © 2012 John Wiley & Sons Ltd.

    The involvement of consumers and the general public in improving cancer services is an important component of health services. However, consumer involvement in cancer research is relatively unexplored. The objective of this study was to explore different ways of involving consumers in cancer research in one regional network. Thames Valley Cancer Network Consumer Research Partnership (CRP) group was formed in 2009. The group consists of consumers and professionals to help in promoting consumer involvement in Cancer Research in the Thames Valley. This study evaluated the project of consumer involvement in cancer research in the Thames Valley from March 2010 to March 2011. We used different indices to judge the level of consumer involvement: number of projects involving consumers through the group, types of projects, level of involvement (ranged from consultation on research documents to collaborating in preparing grant applications) and the methods of involving consumers in cancer research. Fifteen projects were submitted to the CRP group during the 12-month period studied. Of these, eight projects were clinical trials, three were qualitative research projects, two were patients' surveys and two were non-randomized interventional studies. Seven projects requested consumer involvement on patient information sheets for clinical trials. Of these seven applications, three also requested consumers' help in designing research questionnaires and another three requested that consumers should be involved in their project management group. In addition, four projects involved consumers in the proposal development phase and another four projects asked for advice on how to increase trial recruitment, conduct patient interviews or help with grant applications. The creation of the CRP and this audit of its activity have documented consumer involvement in cancer research in the Thames Valley. We have clearly shown that consumers can be involved in designing and managing cancer

    To study the anatomical and histomorphological pattern of extranodal non Hodgkins lymphoma (NHL). Study Design: Descriptive study Place and Duration of Study: The study was carried out at Oncology department Combined Military Hospital Rawalpindi during July 2012 to April 2013. Materials and Methods: All newly diagnosed patients of NHL with extranodal involvement were included in the study. They were categorized as primary extranodal or secondary extranodal lymphomas. Histological pattern and site of involvement were studied. Results: The male to female ratio was 2.2:1 (Male 31, Female 14), and the mean age was 48.16 years (SD=13.40). Primary extranodal involvement was seen in 55.6% of patients. Secondary extranodal involvement was seen in 44.4% of patients. Diffuse large B-cell lymphoma (DLBCL) was the most common type of NHL observed in both primary and secondary extranodal involvement. Gastrointestinal tract was the most common site for primary extranodal involvement and bone marrow was the most common site for secondary extranodal involvement. Conclusion: High frequency of primary extranodal involvement was noted in our study. DLBCL was the most common morphological type observed. Gastrointestinal tract and secondary bone marrow involvement were the most common anatomical sites for primary and secondary extranodal involvement respectively. (author)

    Patient and public involvement (PPI) in clinical trials aims to ensure that research is carried out collaboratively with patients and/or members of the public. However, current guidance on involving clinical trial participants in PPI activities is not consistent. We reviewed the concept of participant involvement, based on our experience. Two workshops were held at the MRCCTU at UCL with the aim of defining participant involvement, considering its rationale; benefits and challenges; and identifying appropriate models for participant involvement in clinical trials. We considered how participant involvement might complement the involvement of other public contributors. Both workshops were attended by two patient representatives and seven staff members with experience of PPI in trials. Two of the staff members had also been involved in studies that had actively involved participants. They shared details of that work to inform discussions. We defined trial participants as individuals taking part in the study in question, including those who had already completed their trial treatment and/or follow-up. Because of their direct experience, involving participants may offer advantages over other public contributors; for example, in studies of new interventions or procedures, and where it is hard to identify or reach patient or community groups that include or speak for the study population. Participant involvement is possible at all stages of a trial; however, because there are no participants to involve during the design stage of a trial, prior to enrolment, participant involvement should complement and not replace involvement of PPI stakeholders. A range of models, including those with managerial, oversight or responsive roles are appropriate for involving participants; however, involvement in data safety and monitoring committees may not be appropriate where there is a potential risk of unblinding. Involvement of participants can improve the trial experience for other

    This study examined demographic and denominational differences in religious involvement (i.e., organizational, non-organizational, subjective) among Caribbean Blacks (Black Caribbeans) residing in the U.S. using data from the National Survey of American Life. Caribbean Blacks who were born in the U.S. had lower levels of religious involvement than those who immigrated and respondents originating from Haiti (as compared to Jamaica) had higher levels of religious involvement, while persons from Trinidad-Tobago reported lower service attendance than did Jamaicans. Older persons, women and married persons generally demonstrated greater religious involvement than their counterparts, while highly educated respondents expressed lower levels of self-rated religiosity. Denominational differences indicated that Baptists reported high levels of religious involvement; however, in several cases, Pentecostals and Seventh Day Adventists reported greater involvement.

    This study explored a relationship between professional involvement and job satisfaction among dietitians. A random sample of 2,600 employed registered dietitians (RDs) received a 55-item questionnaire including a standardized measure of job satisfaction. The response rate was 67.3%; 50.8% were useable (n = 1,321). Ninety-two percent of RDs reported job satisfaction. The mean score was 68.8 +/- .28 (possible range: 18-90), with scores over 54 indicating job satisfaction. A positive relationship was found between job satisfaction and markers of professional involvement. Additionally, six characteristics related to professional involvement were: having had a mentor, being a mentor, self-assessed high professional involvement, full-time employment, high annual income, and increased hours worked per week. There was also a positive relationship between markers of professional involvement and employer support. We conclude that, overall, RDs are satisfied with their jobs and that greater professional involvement is related to greater job satisfaction.

    Homework is a universal practice used in schools, and is commonly related to academic achievement. According to literature, parental homework involvement has positive and negative aspects, depending on parents’ behaviors. Assuming a phenomenographic perspective, this study examined 4th graders’ parents’ conceptions of their involvement in homework. With the purpose of mapping the parents’ various conceptions of homework involvement, 32 semi-structured interviews were conducted and analyzed. The results show that parents’ conceptions of homework involvement have a positive meaning, and focus primarily on the role played in the promotion of academic learning by (a) fostering their children’s autonomy, (b) exerting control over their learning, and (c) providing them with emotional encouragement (when children struggle with difficulties). Given that parents perceive their involvement in their children’s homework as important, it is necessary to promote parent-teacher collaboration and parent-training workshops to improve the quality of parental homework involvement.

    The following study evaluates the complex association between legal involvement and mental illness. It describes a population of consumers of community mental health programs, comparing those with legal involvement to those without legal involvement, on a number of demographic, clinical and social indicators. It is a secondary analysis of data collected in studies making up the Community Mental Health Evaluation Initiative (CMHEI) in the province of Ontario, Canada. Legal involvement was a significant issue among community mental health program consumers; about one in five consumers had at least some contact with the legal system in the preceding nine months. Legally involved consumers were more likely to be in receipt of social assistance and be unstably housed than those legally uninvolved. However, there were no significant differences between legally involved and uninvolved consumers with respect to severity of symptomatology, current medication use or number of hospitalization days in the past 9 months. A predictive model compared the differential impact of clinical and social determinants upon legal involvement. Analyses failed to uncover a significant relationship between severity of psychiatric symptomatology and legal involvement. Significant predictors of legal involvement included gender, race, drug use as well as housing instability, and receipt of social assistance. Legal involvement was attributable to factors other than the severity of mental illness; these results challenge assumptions that the most symptomatically severe consumers are most at risk of legal involvement. Accordingly, the rate of legal involvement in a sample of community mental health program users must be considered in a broad context, with particular emphasis on social disadvantage.

    Following on from the Keogh Report, the need for a framework of service-user involvement exists not just in the health service, but also in higher education. There are wide variances globally in the levels of service-user interaction and involvement in healthcare education. Health policy internationally has indicated a move towards developing partnerships with service users, but to date this remains elusive, with the majority of user involvement consultative in approach. This article aims to discuss the health policy background and the current approaches taken in the involvement of service users in healthcare education.

    Full Text Available Large vessel involvement is one of the hallmarks of Behcet’s disease (BD but its prevalence varies widely due to ethnic variation or environmental factors. The aim of this study is to find the characteristics of vasculo-Behcet (VB in Iran. In a cohort of 4769 patients with BD, those with vascular involvement were selected. Different manifestations of disease were compared with the remaining group of patients. A confidence interval at 95% (CI was calculated for each item. Vascular involvement was seen in 409 cases (8.6%; CI, 0.8. Venous involvement was seen in 396 cases, deep vein thrombosis in 294 (6.2%; CI, 0.7, superficial phlebitis in 108 (2.3%; CI, 0.4 and large vein thrombosis in 45 (0.9%; CI, 0.3. Arterial involvement was seen in 28 patients (25 aneurysms and 4 thromboses. Thirteen patients showed both arterial and venous involvement. The mean age of the patients with VB was slightly higher (P<0.03, but the disease duration was significantly longer (P<0.0003. VB was more common in men. As the presenting sign, ocular lesions were less frequent in VB (P<0.0006, while skin lesions were over 2 times more common in these cases (P<0.000001. VB was associated with a higher frequency of genital aphthosis, skin involvement, joint manifestations, epididymitis, CNS lesions and GI involvement. The juvenile form was less common in VB (P<0.03. High ESR was more frequent in VB (P=0.000002, but the frequency of false positive VDRL, pathergy phenomenon, HLA-B5 or HLA-B27 showed no significant difference between the two groups. In Iranian patients with BD, vascular involvement is not common and large vessel involvement is rare. It may be sex-related, and is more common in well-established disease with multiple organ involvement and longer disease duration.
