    2009-05-13

    The present thesis deals with the spin of charge carriers confined in CdSe/ZnSe quantum dots (QDs) closely linked to the polarization of emitted photons. II-VI material systems can be adequately mixed with the B-group element manganese. Such semimagnetic nanostructures offer a number of characteristic optical and electronic features. This is caused by an exchange interaction between the spin of optically excited carriers and the 3d electrons of the Mn ions. Within the framework of this thesis addressing of well defined spin states was realized by optical excitation of charge carriers. The occupation of different spin states was detected by the degree of polarization of the emitted photoluminescence (PL) light. For that purpose different optical methods of time-resolved and time-integrated spectroscopy as well as investigations in magnetic fields were applied. (orig.)

    In the research project on the ''Review and development of safety-related assessments of disposal facilities with negligible heat generation; development and provision of the necessary set of tools, using the example of the Konrad disposal facility'' (Untersuchung und Entwicklung von sicherheitstechnischen Bewertungen fuer Endlager fuer Abfaelle mit vernachlaessigbarer Waermeentwicklung; Entwicklung und Bereitstellung des notwendigen Instrumentariums am Beispiel des Endlagers Konrad - Forschungsvorhaben 3612R03410), the state of the art in science and technology of the safety-related assessments and sets of tools for building a safety case was examined. The reports pertaining to the two work packages described the further development of the methodology for accident analyses (WP 1) and of building a safety case (WP 2); also, comparisons were drawn on a national and international scale with the methods applied in the licensing procedure of the Konrad disposal facility. As part of the project, the report of Work Package 1 depicts the methodology of the operating safety analysis in order to control malfunctions and incidents (accident analysis) using the example of the Konrad mine accident analysis. Set of criteria in this connection is the state-of-the-art international and national comprehensive body of legislation identifying the incident requirements. In extracts complementary safety analysis procedures of other countries are presented where applicable. It becomes apparent, that the majority of the investigated countries use a deterministic accident analyses to identify incidents. Here, common international practice is to com-plement the deterministic accident analysis by a probabilistic analysis. This procedure acts on the IAEA (International Atomic Energy Agency) terms of reference using both deterministic and probabilistic methods for the determination of facility hazard potentials. Based on the Konrad mine method, aspects of incident

    In the course of examination of the positron and positron-electron pair emission from heavy ion collisions at the Coulomb barrier, the research groups EPOS I and ORANGE have found a number of line structures in the measured positron energy and cumulative pair energy spectra which up to present could not be fully explained, as theoretical interpretations so far remain inconsistent in some respects. For clarification, further measurements have been made at the completely new designed EPoS II spectrometer. Reproducibility of the lines is possible at a high level of statistical significance. (orig./CB) [Deutsch] Bei Untersuchungen der Positron- und Positron- Elektron- Paaremissionaus Schwerionenkollisionen an der Coulombbarriere wurde von den Gruppen EPOS I und ORANGE eine Reihe von Linienstrukturen in den gemessenen Positronenenergie- und Paarsummenenergiespektren beobachtet, fuer die bislang keine in allen Punkten konsistente, theoretische Erklaerunggefunden werden konnte. Um ihre Ursachen zu klaeren, wurden mit dem voellig neu aufgebauten EPoS II Spektrometer weitere Messreihen durgefuehrt. Die Reproduzierbarkeit der Linien ist auf einem hohen statistischen Signifikanzniveau moeglich.

    In August 1993 the first German `Delphi Report on Developments in Science and Technology` was published. It was elaborated by the Fraunhofer Institute for System Engineering and Innovation Research (FhG-ISI) in cooperation with the Japanese National Institute of Science and Technology Policy (NISTEP). The `MINI-DELPHI` now completed by FhG-ISI, again in cooperation with NISTEP, is a further development of the Delphi approach in that it is more differentiated in its questions and assessment criteria than its predecessors. `MINI-DELPHI` is not intended as a comprehensive forecast on technology in general but rather focusses on key topics. Its emphasis is on technology demand and the relevance of technologies to social issues. Although the Mini-Delphi study was primarily aimed at further refining the methodology employed, it nevertheless contains a wealth of information and details on circumscript questions. The requisite database is provided by tables on the results of two inquiry rounds among Japanese and German experts. (orig./RHM) [Deutsch] Im August 1993 wurde der erste deutsche `Delphi-Bericht zur Entwicklung von Wissenschaft und Technik` veroeffentlicht. Er war vom Fraunhofer-Institut fuer Systemtechnik und Innovationsforschung (FhG-ISI) in Zusammenarbeit mit dem japanischen National Institute of Science and Technology Policy (NISTEP) erarbeitet worden. Mit dem jetzt vorliegenden `MINI-DELPHI` hat das FhG-ISI - wieder in Zusammenarbeit mit dem NISTEP - den Delphi-Ansatz fortentwickelt und sowohl hinsichtlich der Fragen als auch der Beurteilungskriterien weiter ausdifferenziert. `MINI-DELPHI` bezweckt keine umfassende Technologievorausschau, sondern konzentriert sich auf Schluesselthemen. Im Vordergrund steht der Gedanke des Technikbedarfs und die Relevanz fuer gesellschaftliche Fragestellungen. Obwohl die Mini-Delphi-Studie vorrangig der Weiterentwicklung der Methodik dient, enthaelt sich eine Fuelle von Informationen und Details zu Einzelfragen. Die im Bericht

    This report, which relates the situation as of July 1997, again confirms the internationally leading role of the Federal German Republic in the phase-out of CFCs. No country has realised a more comprehensive concept for the phase-out of substances that deplete the ozone layer. Combining statutory and voluntary measures has proved a path-breaking approach. One of the most important driving forces in the CFC phase-out were the restrictions of use imposed by the Ordinance on the Prohibition of CFCs and Halon. (orig./SR) [Deutsch] Dieser Bericht - mit Stand vom Juli 1997 - bestaetigt erneut die internationale Fuehrungsrolle der Bundesrepublik Deutschland beim FCKW-Ausstieg. In keinem anderen Staaat wurde ein umfassenderes Konzept zum Ausstieg aus den ozonabbauenden Stoffen realisiert. Als wegweisend hat sich dabei die Verknuepfung ordnungsrechtlicher und freiwilliger Massnahem erwiesen. Insbesondere von den Verwendungsbeschraenkungen der FCKW-Halon-Verbots-Verordnung gingen wichtige Impulse beim FCKW-Ausstieg aus. (orig./SR)

    Arbeit beschaeftigt sich mit einem drei- zu zweiphasigen Matrixumrichter zur Speisung von kontaktlosen Energieuebertragungssystemen. Aufbauend auf einer Darlegung relevanter Untersuchungen zur Thematik werden zunaechst moegliche Resonanzanordnungen fuer kontaktlose Energieuebertragungssysteme untersucht. Die Betrachtung wichtiger elektrischer Parameter zeigt neben den Unterschieden der einzelnen Anordnungen auch, dass fuer eine auf den speisenden Umrichter fokussierte Untersuchung eine einfache Modellierung der drei untersuchten Resonanzanordnungen mit Hilfe eines Reihenschwingkreises moeglich ist. Als Konsequenz ergibt sich die Schlussfolgerung, dass sich die erzielten Ergebnisse auch fuer den Matrixumrichter mit anderen serienresonanten Lasten anwenden lassen. Der zweite Teil der Arbeit ist der Untersuchung des Matrixumrichters gewidmet. Basierend auf einer theoretischen Beschreibung wird die Kombination von hochfrequenten Steuerverfahren - wie z.B. der Blocktaktung - und niederfrequenten Pulsmustern zur Stellung des Oberschwingungsgehalts der Netzstroeme vorgestellt. Die Aehnlichkeit des Umrichters zu einem konventionellen Wechselrichter in H-Brueckenschaltung ermoeglicht anschliessend eine Betrachtung der Kommutierung und die Ableitung notwendiger Schaltzustaende. Diese sind dadurch gekennzeichnet, dass zu jedem Zeitpunkt genau eine bidirektionale Verbindung vom Eingangssystem zu jeder Ausgangsphase besteht. Die Funktionsweise der Kommutierung wie auch des gesamten Umrichters wird in einem ersten Schritt simulativ belegt. Dabei wird auch das dynamische Schaltverhalten der Leistungshalbleiter beruecksichtigt. Anschliessend werden an einem Laboraufbau aufgenommene Messergebnisse vorgestellt und mit den theoretischen Ergebnissen verglichen. Der Laboraufbau besteht aus dem Leistungsteil des Matrixumrichters mit Eingangsfiltern und modularen Gate-Treibern, einem DSP/FPGA-Steuerungssystem und einem kontaktlosen Energieuebertragungssystem mit sekundaerseitigem Gleichrichter

    A study conducted at the IHS had the aim to obtain basic information on whether it is possible to build flow turbines following the free jet principle that are on a par with, or superior to, the conventional design, especially in terms of performance and the efficiency curve. Several inflow contours with a ventilated free jet and a conventional flow turbine were studied. The direct comparison of these variants revealed a slightly enhanced peak load efficiency and a very distinct superiority of the free jet contour during partial load. But the efficiency of all variants failed to attain the values claimed by commercial manufacturers. As compared to the initial contour, peak load efficiency was enhanced by 5 per cent. During partial load, the variants studied showed a distinct superiority of the free jet concept over the contour of conventional flow turbines. (orig.) [Deutsch] Am IHS wurde eine Untersuchung mit dem Ziel durchgefuehrt, grundlegende Aussagen zu gewinnen, ob Durchstroemturbinen mit dem Freistrahlprinzip gebaut werden koennen, die dem konventionellen Design, vor allem in bezug auf Leistungsausbeute und Wirkungsgradverlauf, gleichwertig oder ueberlegen sind. Es wurden mehrere Anstroemkonturen mit belueftetem Freistrahl und einer konventionellen Durchstroemturbine untersucht. Der direkte Vergleich der am Institut untersuchten Varianten ergab bei etwas hoeherem Spitzenwirkungsgrad sehr deutliche Vorteile der Freistrahlkontur im Teillastbereich. Das Wirkungsgradniveau aller Varianten lag jedoch unter den Werten, die von kommerziellen Herstellern veroeffentlicht werden. Gegenueber der Ausgangskontur wurde im Spitzenwirkungsgrad eine Verbesserung von 5% erreicht. Im Teillastbereich ergibt sich fuer die hier untersuchten Varianten eine deutliche Ueberlegenheit der Freistrahlkonzeption ueber die Kontur konventioneller Durchstroemturbinen. (orig.)

    Substance transfer in the boundary layer bulk/biofilm can be only inadequately described by conventional model concepts. In such cases where the surface structure of a biofilm adapts to given hydraulic conditions, the substance transfer phenomena need to be studied in depth. In addition, the entire biofilm structure is much influenced both by substrate conditions and by hydrodynamic conditions during growth. With a view to quantifying these factors, biofilms were cultured under various substrate and hydrodynamic conditions in tube reactors with a diameter of 2.6 cm. For characterizing the cultured biofilms, biofilm density and substrate turnover measured as maximum mass transfer density were determined in each test series. Biofilm density (dry biomass/biofilm volume) was determined by gravimetry. Maximum mass transfer densities in biofilm were established in batch experiments with excess substrate. By means of oxygen microelectrodes, oxygen profiles in the biofilm were measured directly in the reactor. These measurements concerned biofilms of thicknesses ranging from 400 to 2000 {mu}m, where the biofilms did not yet exhibit erosion. (orig.) [German] Der Stoffuebergang in der Grenzschicht Bulk/Biofilm ist mit herkoemmlichen Modellvorstellungen nur ungenuegend beschreibbar. Eine sich an die aktuellen hydraulischen Bedingungen anpassende Oberflaechenstruktur des Biofilms erfordert eine intensive Untersuchung der Stoffuebergangsphaenomene in derartigen Systemen. Darueber hinaus wird die gesamte Biofilmstruktur sowohl von den Substratbedingungen als auch von den hydrodynamischen Bedingungen waehrend des Wachstums stark beeinflusst. Um diese Faktoren quantifizieren zu koennen, wurden Biofilme bei verschiedenen Substrat- und hydrodynamischen Bedingungen in Rohrreaktoren mit einem Durchmesser von 2,6 cm kultiviert. Zur Charakterisierung der kultivierten Biofilme wurde die Biofilmdichte und der Substratumsatz, gemessen als maximale Massestromdichte, bei jeder Versuchsreihe

    Full Text Available Vitamin-D-Mangel ist ein bedeutender Risikofaktor für Knochenbrüche im Alter. Die vorliegende Untersuchung überprüfte die Wirkung einer künstlichen UV-Licht-Bestrahlung auf den Vitamin D-Status, die Parathormonkonzentration im Serum sowie den Knochenabbaumarker NTX im Urin (NTX = quervernetzte N-Telopeptide aus Kollagen Typ 1 bei älteren Frauen im Altersheim. Die UV-Licht-Bestrahlung wurde mit 3 verschiedenen kommerziellen Lampen durchgeführt, die nicht primär für medizinische Anwendungen vorgesehen waren. Es wurden insgesamt 18 Bestrahlungseinheiten über 6 Wochen durchgeführt, wobei die Bestrahlungsdosis jeweils 30 bis 40% der minimalen Erythemschwellendosis betrug. Die Bestrahlung wurde von den Probanden ohne Nebenwirkungen gut vertragen. Vor Beginn der Bestrahlung (im Spätwinter, Februar war der Vitamin-D-Versorgungsgrad der Altersheimbewohnerinnen sehr schlecht (25-Hydroxyvitamin D 25 nmol/l bei mehr als 80 % der Frauen, weiterhin war der Knochenabbaumarker NTX deutlich erhöht. Es kam unter Bestrahlung und auch in der Nachbeobachtungszeit zu keiner signifikanten Änderung der Serumkonzentration von 25-Hydroxyvitamin D und Parathormon, der Knochenabbaumarker NTX zeigte in einer Gruppe einen leichten Rückgang. Es zeigte sich weiterhin eine erwartete inverse Korrelation der Serumkonzentration von Parathormon mit 25-Hydroxyvitamin D (r = –0,19; p 0,03 und überraschend eine positive Korrelation zwischen Kalzium und Parathormon (r = 0,24; p 0,02, auf eine autonomisierte Parathormonsekretion bei einigen Frauen hinweisend. Parathormon war weiterhin positiv mit dem Knochenabbaumarker NTX korreliert (r = 0,21; p 0,026, dagegen gab es keine signifikante Korrelation zwischen 25-Hydroxyvitamin D und dem Knochenabbaumarker NTX (p = 0,83 und auch nicht zwischen 25-Hydroxyvitamin D und der alkalischen Phosphatase (r = –0,04, p = 0,648. Fazit: Das durchgeführte Bestrahlungsprotokoll konnte den Vitamin D-Status nicht signifikant verbessern

    sowie die Untersuchung unter Einschluss funktioneller Tests stehen wie immer am Anfang der diagnostischen Strategie; wobei der Verletzungsmechanismus und das sportspezifische Belastungsmuster beruecksichtigt werden muessen. Regionale Inspektions-, Palpations- und Testbefunde der verletzten Struktur weisen auf eine Verdachtsdiagnose hin, die durch bildgebende Verfahren bestaetigt oder auch widerlegt werden kann. Durch den effizienten Einsatz bildgebender Methoden kann dann rasch die entsprechende Therapie eingeleitet werden. Die Sonographie gibt hier, aufgrund ihrer raschen Verfuegbarkeit, vor allem im Bereich von Muskeln, Sehnen und Baendern u. U. wertvolle Hinweise. Die nativradiologische Abklaerung im Bereich des Knochens muss oft durch Zielaufnahmen ergaenzt werden. Die MRT stellt im Bereich der Gelenkverletzungen den Goldstandard dar, wobei eine exakte differenzialdiagnostische Fragestellung hilfreich ist, das Untersuchungsprotokoll entsprechend durchzufuehren, um die fraglich pathologischen Strukturen moeglichst klar darzustellen.

  7. Investigation of a transsonic slot cooling system for high-temperature gas turbine blades; Untersuchung einer transsonischen Schlitzkuehlung fuer Hochtemperaturgasturbinenschaufeln

    The author investigated a slot cooling system with transsonic blowout of cooling air for high-temperature gas turbine blades. The method has the advantage that the cooling film is closer to the blade surface and the boundary layer at the blade wall is not interrupted even at high blowout rates. This way, the cooling film will mix less with the hot gas flow, and the cooling effect will last longer. The method is based on the subsonic Coanda effect and the supersonic Prandtl-Meyer effect, both of which result in attachment of the cooling film to a curved surface. The investigations and the optimisation were carried out using the experimental system, measuring instruments and software of the Institute of Thermal Turbo-Engines and Machine Dynamics. [German] In dieser Arbeit wird eine Schlitzkuehlung mit transsonischer Kuehlluftausblasung fuer Hochtemperaturgasturbinenschaufeln untersucht. Der Vorteil dieser Kuehlmethode ist, dass der entstehende Kuehlfilm besser an die Schaufeloberflaeche anliegt und die Grenzschicht an der Schaufelwand auch bei hohen Ausblasraten nicht durchstossen wird. Dies bewirkt ein geringeres Vermischen des Kuehlfilms mit der heissen Gasstroemung und somit ein laengeres Anhalten des Kuehlungseffektes. Man bedient sich dabei zweier in der Stroemungslehre bekannter Effekte, naemlich dem subsonischen Coanda Effekt und dem im Ueberschall auftretenden Prandtl-Meyer Effekt. Beide bewirken das Anlegen der Kuehlfilme an eine gekruemmte Oberflaeche. Mit Hilfe der am Institut fuer thermische Turbomaschinen und Maschinendynamik zur Verfuegung stehenden Versuchsanlagen, Messgeraete und Software wurde die Untersuchung bzw. Optimierung der transsonischen Schlitzkuehlung durchgefuehrt. (orig.)

The positive trends continued in some fields, especially in the case of chloride concentrations and freights. On the other hand, there was a significant increase of some organic pollutants like DTPA, glyphosate and AMPA. The microbiological specifications of the new Drinking Water Ordinance and the concentrations of tensides and their metabolites are gone into.

    Cardiovascular magnetic resonance imaging (CMR) has become a routinely used imaging modality for congenital heart disease. A CMR examination allows the assessment of thoracic anatomy, global and regional cardiac function, blood flow in the great vessels and myocardial viability and perfusion. In the clinical routine cardiovascular MRI is mostly performed at field strengths of 1.5 Tesla (T). Recently, magnetic resonance systems operating at a field strengths of 3 T became clinically available and can also be used for cardiovascular MRI. The main advantage of CMR at 3 T is the gain in the signal-to-noise ratio resulting in improved image quality and/or allowing higher acquisition speed. Several further differences compared to MRI systems with lower field strengths have to be considered for practical applications. This article describes the impact of CMR at 3 T in patients with congenital heart disease by meanings of methodical considerations and case studies. (orig.) [German] Die kardiovaskulaere Magnetresonanztomographie (MRT) hat sich zu einer etablierten bildgebenden Methode zur Untersuchung von Patienten mit angeborenen Herzfehlern entwickelt. Sie erlaubt in einer einzigen Untersuchung die exakte Beurteilung von Anatomie, globaler und regionaler Funktion, Blutfluessen sowie der myokardialen Perfusion und Vitalitaet. In der klinischen Routine erfolgen die Untersuchungen zumeist bei einer Feldstaerke von 1,5 Tesla (T), mittlerweile gibt es jedoch Geraete und Bildgebungstechniken, die die kardiovaskulaere MRT auch bei 3 T ermoeglichen. Der wesentliche Vorteil der MRT bei 3 T ist das hoehere Signal-zu-Rausch-Verhaeltnis, das sowohl zu einer Verbesserung der Bildqualitaet als auch zu einer Verkuerzung der Untersuchungszeit genutzt werden kann. Darueber hinaus bestehen verschiedene andere Unterschiede gegenueber Systemen mit niedriger Feldstaerke, die im praktischen Einsatz beachtet werden muessen. Dieser Artikel beschreibt die Erfahrungen der 3-T-MRT fuer die

    The penstock of the hydropower plant in Kaprun was built during and after World War II under difficult conditions and after 60 years in use it was abandoned in 2004. The longitudinal joint partly has been done by water gas welding, wherefore detailed analysis is still missing. The joint, which is a result of the mechanical treatment (rolling or forging) of the heated based material below melting temperature, is characterized by a very narrow and small HAZ. The characterization of the base material and the welding joint was performed by using the substantial results of more then 80 small sized and 2 large sized specimens. Furthermore this work includes the determination of fracture mechanic properties. The parameters were validated by comparing the results with the integral tensile test specimen containing a flaw. Therefore one is able to evaluate failure in those joints applying this fracture mechanic approach. (orig.)

    Purpose: To describe the incidence, time course, and clinical correlates of hemorrhagic transformation (HT) of ischemic stroke in the posterior cerebral artery territory. Methods: Within 42 months 48 patients with 52 occipital lobe infarctions were examined by T{sub 1}- and T{sub 2}-weighted MR imaging. The extent and distribution of secondary hemorrhage were analysed at different intervals after stroke. Volume of ischemic and hemorrhagic infarction was measured planimetrically. Results: HT was observed in 71% of the infarcts between the 5{sup th} day and up to 1 year after stroke. HT was most frequently (88%) observed in the 2{sup nd} and 3{sup rd} month. HT was present in 55% of small infarcts (<10 cm{sup 3}), in 88% of medium size (10-50 cm{sup 3}), and in all large (>50 cm{sup 3}) infarcts. In 92% HT presented with petechial bleedings within the cortex (64%) or less frequently (28%) in subcortical structures. The latter types of HT showed no progression and did not increase the clinical deficits. Space-occupying bleedings occurred in only two large defects. Conclusions: In ischemic posterior infarction, HT can frequently be detected within the first three months after stroke and is predominantly of the petechial type and seems not to be relevant with regard to clinical deficits.

    The periodic instationary flow in guidevanes and runner of an axial hydraulic turbine is examined experimentally and numerically. The study is carried out at three different points of operation. The experimental study comprises the measurement of the velocity of the flow at midspan using a single channel Laser Doppler Velocimeter and the acquisition of the ozillating pressure at several locations in the casing. The unsteady numerical examination is carried out in a two dimensional plane at midspan of the runnerblades. The interaction between guidevanes and runner is taken into account by exchanging the flow properties at the adjoining edges of the two calculation grids. Further the influence of the tip clearance flow on the characteristics of the turbine is studied numerically by means of a three dimensional steady state calculation. The comparison of the results of measurement and calculation shows the abilities and the limitations of the applied numerical method. Moreover the results are helpful for the optimisation of the turbine with regard to higher efficiency and reduced cavitation. (orig.)

    The issue of the contribution is the characterization of under-clad and surface crack behaviour in ferritic steel components with an austenitic welded cladding. The experimental investigations were performed using large-scale samples. The residual stress field was determined in detail by a numerical simulation of the welding and heat treatment processes. These results were used for the numerical simulation of crack initiation and crack arrest. In all evaluated cases the crack was initiated in the ferritic material, while the cladding stayed intact even in case of a crack jump in the base metal. In the frame of case studies the results were transferred to application relevant geometries. [German] Der Gegenstand des vorliegenden Beitrags ist eine Charakterisierung des Verhaltens von Unterplattierungs- und Oberflaechenfehlern in Komponenten aus ferritischen Staehlen mit einer austenitischen Schweissplattierung. Im Rahmen einer experimentellen Untersuchung wurden hierzu zwei Versuche an Grossproben durchgefuehrt. Das Eigenspannungsfeld wurde detailliert durch eine numerische Simulation der Schweiss- und Waermebehandlungsprozesse bestimmt. Unter Verwendung dieser, an anderer Stelle praesentierten Ergebnisse erfolgte eine numerische Simulation der Bauteilversuche zur genauen Bestimmung der Verhaeltnisse bei Rissinitiierung und Rissarrest. In allen untersuchten Faellen zeigte sich, dass der Bruch im ferritischen Bereich ausgeloest wurde, waehrend die Plattierung auch bei einem Risssprung im Grundwerkstoff intakt blieb. Im Rahmen von Fallstudien wurden die Ergebnisse auf anwendungsrelevante Geometrien uebertragen. (orig.)

    Introduction: motivated by the difficulties often encountered in the setup of respiratory trigger in MR imaging of mechanical ventilated pediatric patients, a simplified approach in terms of time and reliability was sought. Method: with the help of a male-to-male Luer-Lock adapter in combination with a 3-way adapter the tube of the respiratory compensation bellow was fixed to the output channel for capnography of the airway filter. Ten patients (age 4 months to 6 years) were tested with spin echo imaging and either respiration compensation (T1-weighted imaging) or respiratory triggered (T2-weighted imaging). Results: a clear trigger signal was achieved in all cases. No negative influence on the quality or security of the mechanical ventilation of the patients was observed. Summary: the proposed adapter is safe, efficient and fast to install in patients undergoing MR imaging in general anaesthesia. (orig.) [German] Einleitung: Bei beatmeten Patienten, insbesondere bei Saeuglingen und Kleinkindern, kann es schwierig sein, ein geeignetes Atemsignal fuer die Triggerung der MR-Bildgebung zu erhalten. Eine einfache und schnell zu installierende technische Modifikation wurde gesucht, um ein verlaessliches Atemsignal fuer die atemgetriggerte Untersuchung zu erreichen. Material, Methoden, Ergebnisse: Mithilfe eines handelsueblichen Adapters wurde der Atemwegsdruck bei beatmeten Patienten als Triggersignal fuer atemkompensierte oder atemgetriggerte Sequenzen in der MRT abgeleitet. Dafuer wurde der Schlauch des am MRT vorhandenen Atemgurtes ueber einen Dreiwegehahn und einen Luer-Lock maennlich-maennlich Adapter mit dem fuer die Kapnographie vorgesehenen Filteranschluss verbunden. Die sehr rasch zu montierende Technik wurde bei 10 Patienten im Alter von 4 Monaten bis 6 Jahren erfolgreich getestet. In allen Faellen wurde ein verlaessliches, klares Signal gewonnen. Es kam zu keiner Beeintraechtigung der Beatmung. Schlussfolgerung: Der vorgestellte Aufbau ist eine praktische

  14. LAMPF II

    International Nuclear Information System (INIS)

    We present a plan for two rapid-cycling synchrotrons - a 45 GeV, 40 μA proton synchrotron with a 9 GeV, 200 μA booster. These machines can provide simultaneously 45 GeV slow-extracted beam for the production of kaons, antiprotons, and other secondary particles, and 9 GeV fast-extracted beam for neutrino and pulsed muon physics. The LAMPF II machines are compared with existing and proposed kaon factories. Relative to the Brookhaven AGS as it exists today, LAMPF II will provide 90 times as many neutrino events per year and 300 times as many kaons per year. Some design features of the LAMPF II accelerators that are important for reducing beam losses and increasing beam availability are discussed. Because of the large rf power and voltage required, an innovative design of the ferrite-tuned cavities is necessary. A commercially available Mg-Mn ferrite with perpendicular bias has been shown to raise the available ferrite Q by more than a factor of 10 when compared with materials now in use at other accelerators. The 45 GeV LAMPF II synchrotron would produce far more neutrinos, kaons, and antiprotons per unit cost than an upgraded conventional machine. The LAMPF II booster by itself, which can provide 100 μA at 12 GeV, is a very interesting option at moderate cost. (orig.)

A number of experiments requiring vastly increased beam current are examined. Two programs, the search for quark-gluon plasma using high-energy antiproton annihilation in nuclei, and the measurement of nuclear quark structure functions using the Drell-Yan process, address the highest priority problems of the NSAC long-range plan. Some of the design features of the LAMPF II accelerators are shown to be important for reducing beam losses and increasing beam availability. Because of the large rf power and voltage required, innovation on ferrite-tuned cavities is required. A commercially available Mg-Mn ferrite with perpendicular bias has been shown to raise the available ferrite Q by more than a factor of 10 compared with the materials now in use at other accelerators. A preliminary cost estimate is discussed. The cost of the LAMPF II machine is compared with estimates of several other proposed machines made with the same set of costing algorithms. The 45-GeV LAMPF II proposal produces far more neutrinos, kaons, and antiprotons per unit cost than an upgraded conventional machine. The LAMPF II booster alone, which can provide 100 μA at 12 GeV, is shown to be a very interesting option at moderate cost

    Only little attention is directed towards nonrespiratory functions of the lung in today`s nuclear medicine. However, the metabolic performance of the lung (e.g. the handling of biologically active amines) is of major importance for the whole organism. The main site for metabolic lung functions is the endothelium. Nuclear medicine methods are suitable for the noninvasive evaluation of the functional status of endothelial cells. After i.v. injection, MIBG is taken up by the pulmonary endothelium analogous to norepinephrine. Consequently, dysfunction of the endothelium can be recognized early by lung scintigraphy with MIBG. Since MIBG competes with norepinephrine at the cellular up-take mechanism, MIBG scintigraphy of the lung gives also insight into the function of the systemic neuroadrenergic system. MIBG radioaerosol may be of potential use for the assessment of the neuroadrenergic function of the airways. Even though the feasibility of the method has been demonstrated, clinical studies are lacking so far. (orig.) [Deutsch] Nichtrespiratorische Lungenfunktionen spielen derzeit in der nuklearmedizinischen Diagnostik nur eine untergeordnete Rolle. Fuer den Gesamtorganismus jedoch hat die Lunge als biochemischer Filter (z.B. von biologisch aktiven Aminen) eine erhebliche Bedeutung. Hauptort der metabolischen Leistung der Lunge ist das Endothel. Als bildgebende Verfahren zur Untersuchung der Funktion des pulmonalen Endothels bieten sich nuklearmedizinische Methoden an. MIBG wird nach intravenoeser Injektion analog zu Noradrenalin in pulmonale Endothelzellen aufgenommen. Die MIBG-Szintigraphie der Lunge stellt somit eine einfache nichtinvasive Methode dar, Funktionstoerungen des pulmonalen Endothels fruehzeitig zu erfassen. Da die pulmonale MIBG-Speicherung auch von der Kompetition zwischen MIBG und zirkulierendem Noradrenalin am spezifischen Transportmechanismus abhaengt, erlaubt die MIBG-Szintigraphie der Lunge auch Aussagen zur Funktion des systemischen

    Purpose of this study was to evaluate the diagnostic value of a low field dedicated MRI system in hand and wrist imaging. All 308 exams of the hand and wrist, that were performed on a low-field dedicated MRI system (Artoscan, Esaote Biomedica, Italy) in our institution in 1996, and high-field MRI exams performed in addition as part of the diagnostic work-up, were evaluated and correlated to final operative (n=64) and histologic (n=12) reports. 90% of all low-field MRI scans stated a diagnosis according to clinical suspicion. In 62% the clinical question was answered, and in 26% additional pathologies were identified. An MR-diagnosis completely different from the clinical suspicion was stated in 2%. High field exams contributed additional information in 6 to 36 patients. In 3 patients a tumor was not shown completely in the limited field-of-view of the dedicated low-field MRI-system. Frequency-selective fat-suppression pulse sequences and a better spatial resolution were the reasons for the additional information obtained in the other three patients. Low-field dedicted MR-imaging is a valuable method in the extensive work-up of the hand and wrist. Osseous, ligamentous and tendinous pathologies are well depicted. Large or infiltrative tumors should be referred to a high-field system. (orig.) [Deutsch] Ziel der Untersuchung war die Bestimmung der diagnostischen Wertigkeit eines dedizierten MRT-Niederfeldsystems (0,2 Tesla, Esaote, Genua, Italien) bei Untersuchungen von Hand und Handgelenk. 1996 wurden an unserem Institut insgesamt 308 Untersuchungen an einem dedizierten Niederfeld-MRT-System durchgefuehrt. Zusatzuntersuchungen am Hochfeld-MR-Tomographen (Magnetom Impact, 1,0 Tesla oder Magnetom Vision, 1,5 Tesla, Siemens AG, Erlangen) wurden bei 36 Faellen ergaenzt. 64 (21%) der Faelle wurden operativ behandelt.

  5. Bromide as a tracer for studying water movement and nitrate displacement in soils: comparison with stable isotope tracers; Bromid als Tracer zur Untersuchung der Wasserbewegung und der Nitratverlagerung in Boeden: Vergleich mit stabilisotopen Tracern

    Tracers are an ideal means of studying water movement and associated nitrate displacement. Often bromide is preferred as a tracer because it is considered a representative tracer for water and because, being a conservative tracer (i.e. not involved in chemical and biological soil processes), it can be used for studying anion transport in soils. Moreover, it is less expensive and easier to measure than the stable isotopes deuterium and {sup 15}N. Its great advantage over radioactive tracers (e.g. tritium), which outweighs their extreme sensitivity and ease of measurement and which it has in common with stable isotopes, is that it does not require radiation protection measures. However, there are also constraints on the use of bromide as a tracer in soil/water/plant systems. Our own studies on different soils using D{sub 2}O, bromide and [{sup 15}N]-nitrate in lysimeters suggest that the above assumptions on bromide tracers need not always be valid under conditions as they prevail in biologically active soils. As the present paper shows, these studies permit a good assessment of the possibilities and limits to these tracers. [Deutsch] Fuer die Untersuchung der Wasserbewegung sowie der daran gekoppelten Nitrat-Verlagerung ist der Einsatz von Tracern das Mittel der Wahl. Dabei wird Bromid als Tracer haeufig bevorzugt, da es allgemein als ein repraesentativer Tracer fuer Wasser und als konservativer Tracer (nicht involviert in chemische und biologische Bodenprozesse) zur Untersuchung des Anionentransportes in Boeden angesehen wird und es gegenueber den stabilen Isotopen Deuterium und {sup 15}N billiger und einfacher zu bestimmen ist. Gegenueber den radioaktiven Tracern (z.B. Tritium), die zwar sehr empfindlich und einfach messbar sind, besteht der grosse Vorteil, dass, wie bei den stabilen Isotopen, keine Strahlenschutzmassnahmen ergriffen werden muessen. Es gibt jedoch auch einschraenkende Hinweise fuer die Verwendung von Bromid als Tracer im System Boden

    detaillierte Kenntnisse der an den Elektroden ablaufenden Reaktionsmechanismen. In der vorliegenden Arbeit wird der komplexe anodenseitige Reaktionsmechanismus in der Karbonat-Brennstoffzelle detailliert untersucht, mit dem Ziel, ein grundlegendes Verstaendnis ueber die an der Anode stattfindenden physikalischen und elektrochemischen Prozesse zu entwickeln und Einflussgroessen auf die Leistung der Brennstoffzellen-Stapel zu identifizieren. Dazu zaehlen die eingehende Untersuchung der parallel stattfindenden Oxidationsreaktionen von Wasserstoff und Kohlenmonoxid und ihrer reaktionstechnischen Parameter, die detaillierte Analyse von Stofftransport, Adsorption und Ladungstransport und die Betrachtung von Degradationsphaenomenen, welche sich degressiv auf Zellleistung und Lebensdauer auswirken. Fuer die experimentellen Untersuchungen stehen verschiedene Versuchsanlagen zur Verfuegung. Dazu zaehlen vorrangig Anoden-Halbzellen und Einzelzellen. Werkzeug zur Analyse der physikalischen und elektrochemischen Phaenomene ist die elektrochemische Impedanzspektroskopie (EIS), deren Ergebnisse in die Entwicklung eines Ersatzschaltbilds einfliessen. Die Verknuepfung der Elemente des Ersatzschaltbilds mit physikalischen Prozessgroessen erfolgt im Rahmen eines numerischen Modells fuer die MCFC-Anode. Die Impedanzspektren der MCFC-Anoden ergeben vier charakteristische Widerstaende: ohmscher Widerstand, hochfrequenter Widerstand, niederfrequenter Widerstand und Gesamtwiderstand. Der stark temperaturabhaengige hochfrequente Widerstand wird von der Elektrodenkinetik beeinflusst, waehrend der Stofftransport durch den niederfrequenten Widerstand ausgedrueckt wird. Es zeigt sich, dass die in der Literatur postulierten Mechanismen fuer die anodenseitige Oxidation von Wasserstoff unvollstaendig sind. Die Oxidation des Wasserstoffs folgt einer Reaktionsgeschwindigkeit (pseudo) negativer Ordnung. Voraussetzung hierfuer sind zwei adsorbierende, miteinander reagierende Spezies.

    The present report contains the result of a research project on `Technology assessment with regard to the environment` which was commissioned by the Federal Ministry for Research and Technology (BMFT) and carried out jointly by the GSF Research Centre for Environment and Health (GSF) and the Institute for Applied Innovation Research (IAI). In this project the Law on Protection from Harzardous Substances (Law on Chemicals) was used to exemplify the procedure of assessing the consequences of legislation in the area of environmental law. The project proposal distinguished three project phases. In the first an exemplary ex post analysis was to be carried out on a significant legal regulation (the Law on Chemicals) concerning a specific branch of industry generally considered innovative (the chemical industry). In this way it was intended to collect empirical knowledge on how regulations affect innovation processes in the individual company. In the second phase the planned amendment of the Law on Chemicals was to serve as a case example for an assessment of the consequences of legislation. In the third project phase the methodology employed in the former was to be extended for the purpose of developing an instrumentarium for the ex ante assessment of legislation. Such an instrument could permit both the corporate innovator and the innovation promoter to assess the effets of environmental legislation at the corporate level and thus develop an anticipatory conflict management.

    We study type II universal metrics of the Lorentzian signature. These metrics simultaneously solve vacuum field equations of all theories of gravitation with the Lagrangian being a polynomial curvature invariant constructed from the metric, the Riemann tensor and its covariant derivatives of an arbitrary order. We provide examples of type II universal metrics for all composite number dimensions. On the other hand, we have no examples for prime number dimensions and we prove the non-existence of type II universal spacetimes in five dimensions. We also present type II vacuum solutions of selected classes of gravitational theories, such as Lovelock, quadratic and L({{Riemann}}) gravities.

    1994-12-31

    All investigations of this doctoral thesis were conducted on alloys of the systems AlAg and AlLi. Therefore the introductory Chapter I gives a report on the most important properties of these alloys in due brevity and explains the physical background of the experiments conducted. Chapter II presents experiments relating to the early stages of demixing of an oversaturated AlLi alloy. The determination of the size spectrum of the precipitations using high-resolution electron microscopy furnishes information which is essential to an understanding of the demixing process. Chapter III describes investigations into the behavior of the intermetallic {delta}`-phase in the system AlLi under electron irradiation. These experiments involve use of the electron microscope not only as an imaging instrument, but also as a source of radiation. The methodologically oriented final section of the present thesis (Chapter IV) investigates ``hollow cone wide angle dark field imaging`` as an advanced chemically sensitive imaging method which supplies information on the chemical composition of the sample on a nm scale, while requiring only little equipment.

    The present Part I of the final report covers theoretical investigations relating to the project; Part II presents the results of experimental work. The finite element method (FEM) is used to calculate the natural oscillation behaviour of coupled blade systems in axial-flow turbomachines. This involved combining the propagating wave method, which utilises the periodicity of such structures and substantially reduces computational effort, with existing FEM software systems (ASKA, PERMAS, NOVA). The static condition of pre-stress condition in the blades caused by the centrifugal force field and influencing the natural frequency can also be calculated by taking into account geometrically non-linear effects. Based on this condition, the equation of motion is linearised taking into account of centrifugal forces during oscillatory motion. When modelling a coupled blading, exceptions in respect of the forces and moments transmitted between the blade and the coupling element must be given special consideration. The natural frequencies obtained for different configurations and model formations are compared to resonance frequencies determined by experiments to support these coupling conditions. The discussion of natural oscillation modes of a model blading gives a deeper insight into the physical conditions of different types of coupled axial bladinngs. Based on the natural oscillation calculation of a real output stage blading,it is shown that the calculation method can also be used to analyse natural frequencies of complex structures. (orig.)

The elemental analyses suggest the stoichiometry to be 1:2 (metal:ligand. Magnetic susceptibility data coupled with electronic, ESR and Mössbauer spectra suggest a distorted octahedral structure for the Fe(II, Co(II and Ni(II complexes, a square-planar geometry for the Cu(II compound and a tetrahedral geometry for the Zn(II and Cd(II complexes. The infrared and NMR spectra of the complexes agree with co-ordination to the central metal atom through nitrogen and sulphur atoms. Conductance measurements suggest the non-electrolytic nature of the complexes, except for the Cu(II, Zn(II and Cd(II complexes, which are 1:2 electrolytes. The Schiff base and its metal chelates were screened for their biological activity against Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa and the metal chelates were found to possess better antibacterial activity than that of the uncomplexed Schiff base.

    The Belle II experiment will record a similar quantity of data to LHC experiments and will acquire it at similar rates. This requires considerable computing, storage and network resources to handle not only data created by the experiment but also considerable amounts of simulated data. Consequently Belle II employs a distributed computing system to provide the resources coordinated by the the DIRAC interware. DIRAC is a general software framework that provides a unified interface among heterogeneous computing resources. In addition to the well proven DIRAC software stack, Belle II is developing its own extension called BelleDIRAC. BelleDIRAC provides a transparent user experience for the Belle II analysis framework (basf2) on various environments and gives access to file information managed by LFC and AMGA metadata catalog. By unifying DIRAC and BelleDIRAC functionalities, Belle II plans to operate an automated mass data processing framework named a “production system”. The Belle II production system enables large-scale raw data transfer from experimental site to raw data centers, followed by massive data processing, and smart data delivery to each remote site. The production system is also utilized for simulated data production and data analysis. Although development of the production system is still on-going, recently Belle II has prepared prototype version and evaluated it with a large scale simulated data production. In this presentation we will report the evaluation of the prototype system and future development plans.

  7. Workshop on TARN II

    International Nuclear Information System (INIS)

    This note is a collection of the reports at the workshop on TARN II which was held on 23-24 March, 1990 at INS, University of Tokyo. The workshop was meant to understand the status of the synchrotron-cooler ring TARN II and to study on the possibilities of its applications to the physics research. Many interesting talks were presented for the acceleration and the physics. Despite a progress of R and D for the TARN II, there is still a large gap between the present performance and the physics requirement for the TARN II. It is a important problem in future how to solve this discrepancy. The 17 of the presented papers are indexed individually. (J.P.N.)

    Full Text Available The anti-inflammatory properties of PPAR-α plays an important role in attenuating hypertension. The current study determines the anti-hypertensive and anti-inflammatory role of PPAR-α agonist during a slow-pressor dose of Ang II (400 ng/kg/min. Ten to twelve week old male PPAR-α KO mice and their WT controls were implanted with telemetry devices and infused with Ang II for 12 days. On day 12 of Ang II infusion, MAP was elevated in PPAR-α KO mice compared to WT (161±4 mmHg versus 145±4 mmHg and fenofibrate (145 mg/kg/day reduced MAP in WT + Ang II mice (134±7 mmHg. Plasma IL-6 levels were higher in PPAR-α KO mice on day 12 of Ang II infusion (30±4 versus 8±2 pg/mL and fenofibrate reduced plasma IL-6 in Ang II-treated WT mice (10±3 pg/mL. Fenofibrate increased renal expression of CYP4A, restored renal CYP2J expression, reduced the elevation in renal ICAM-1, MCP-1 and COX-2 in WT + Ang II mice. Our results demonstrate that activation of PPAR-α attenuates Ang II-induced hypertension through up-regulation of CYP4A and CYP2J and an attenuation of inflammatory markers such as plasma IL-6, renal MCP-1, renal expression of ICAM-1 and COX-2.

    within the material structure. The results of the investigation indicated that rather the fatigue related changes in material behavior are mainly a result of viscous processes in cement stone especially in phase I and II of the fatigue process. Furthermore, it was observed that creep in concrete leads to similar but lesser changes in material behavior of concrete. Beside this, tests with different scales of specimens have shown an appreciable effect of size on the resulting material behavior under static and cyclic loadings respectively. From these experimental findings a detailed description was derived about the processes which take place within the material structure during the fatigue loading and also leads to the observed macroscopic changes in material behavior. In this context, the tests have shown that relating to stiffness reduction a scalar value could not capture the damage effect on the stressstrain- relationship caused by fatigue. A following consideration gives an overview about applicability of the different measured parameters for the detection of the degree of fatigue damage with regard to a reliable damage indicator. Finally an approach is presented which is able to describe the investigated developments of significant values within the observed fatigue process.

    Purpose: Differentiation and assessment of intra- (IMCL) and extramyocellular lipids (EMCL) in offspring of type II diabetic subjects by means of {sup 1}H-MR-spectroscopy. Methods: Out of a group of more than 250 metabolically characterized offspring of type II diabetics, twenty subjects were selected and matched for anthropometric parameters. Glucose clamp was performed prior to MRS in all subjects for metabolic characterization. Ten individuals were classified as insulin resistant (MCR<7 ml/kg/min) and ten were found to be insulin sensitive (MCR>7 ml/kg/min). MRS was performed in the tibialis anterior muscle and in the soleus muscle. Results: For insulin resistant individuals the MRS results revealed a higher IMCL content in both muscles. In the tibialis anterior muscle IMCL was increased by 1.6 fold (arbitrary units {+-}SEM: 3.2{+-}0.4 vs 2.0{+-}0.3; p<0.01) and in the soleus muscle by 2.0 fold (arbitrary units {+-}SEM: 13.0{+-}1.9 vs 6.6{+-}0.9; p{<=}0.01). There was no correlation between EMCL and MCR in the soleus muscle. In addition, no relationship between the amount of IMCL and the subcutaneous fat layer was found. Conclusions: A significantly increased intramyocellular lipid content in insulin resistant offspring of type II diabetic subjects was assessed non-invasively by {sup 1}H-MR-spectroscopy. (orig.)

    Background: Carnitine palmitoyltransferase II (CPT II) deficiency is an important cause of recurrent rhabdomyolysis in children and adults. Current treatment includes dietary fat restriction, with increased carbohydrate intake and exercise restriction to avoid muscle pain and rhabdomyolysis. Methods: CPT II enzyme assay, DNA mutation analysis, quantitative analysis of acylcarnitines in blood and cultured fibroblasts, urinary organic acids, the standardized 36-item Short-Form Health Status survey (SF-36) version 2, and bioelectric impedance for body fat composition. Diet treatment with triheptanoin at 30% to 35% of total daily caloric intake was used for all patients. Results: Seven patients with CPT II deficiency were studied from 7 to 61 months on the triheptanoin (anaplerotic) diet. Five had previous episodes of rhabdomyolysis requiring hospitalizations and muscle pain on exertion prior to the diet (two younger patients had not had rhabdomyolysis). While on the diet, only two patients experienced mild muscle pain with exercise. During short periods of noncompliance, two patients experienced rhabdomyolysis with exercise. None experienced rhabdomyolysis or hospitalizations while on the diet. All patients returned to normal physical activities including strenuous sports. Exercise restriction was eliminated. Previously abnormal SF-36 physical composite scores returned to normal levels that persisted for the duration of the therapy in all five symptomatic patients. Conclusions: The triheptanoin diet seems to be an effective therapy for adult-onset carnitine palmitoyltransferase II deficiency.

    The operation of an APPLE II based undulator beamline with all its polarization states (linear horizontal and vertical, circular and elliptical, and continous variation of the linear vector) requires an effective description allowing an automated calculation of gap and shift parameter as function of energy and operation mode. The extension of the linear polarization range from 0 to 180 deg. requires 4 shiftable magnet arrrays, permitting use of the APU (adjustable phase undulator) concept. Studies for a pure fixed gap APPLE II for the SLS revealed surprising symmetries between circular and linear polarization modes allowing for simplified operation. A semi-analytical model covering all types of APPLE II and its implementation will be presented

  7. Results from SAGE II

    International Nuclear Information System (INIS)

    The Russian-American Gallium solar neutrino Experiment (SAGE) began the second phase of operation (SAGE II) in September of 1992. Monthly measurements of the integral flux of solar neutrinos have been made with 55 tonnes of gallium. The K-peak results of the first nine runs of SAGE II give a capture rate of 66-13+18 (stat) -7+5 (sys) SNU. Combined with the SAGE I result of 73-16+18 (stat) -75 (sys) SNU, the capture rate is 69-11+11 (stat) -7+5 (sys) SNU. This represents only 52%--56% of the capture rate predicted by different Standard Solar Models

  1. Role of Bound Zn(II) in the CadC Cd(II)/Pb(II)/Zn(II)-Responsive Repressor

    2009-01-01

    The Staphylococcus aureus plasmid pI258 cadCA operon encodes a P-type ATPase, CadA, that confers resistance to Cd(II)/Pb(II)/Zn(II). Expression is regulated by CadC, a homodimeric repressor that dissociates from the cad operator/promoter upon binding of Cd(II), Pb(II), or Zn(II). CadC is a member of the ArsR/SmtB family of metalloregulatory proteins. The crystal structure of CadC shows two types of metal binding sites, termed Site 1 and Site 2, and the homodimer has two of each. Site 1 is the physiological inducer binding site. The two Site 2 metal binding sites are formed at the dimerization interface. Site 2 is not regulatory in CadC but is regulatory in the homologue SmtB. Here the role of each site was investigated by mutagenesis. Both sites bind either Cd(II) or Zn(II). However, Site 1 has higher affinity for Cd(II) over Zn(II), and Site 2 prefers Zn(II) over Cd(II). Site 2 is not required for either derepression or dimerization. The crystal structure of the wild type with bound Zn(II) and of a mutant lacking Site 2 was compared with the SmtB structure with and without bound Zn(II). We propose that an arginine residue allows for Zn(II) regulation in SmtB and, conversely, a glycine results in a lack of regulation by Zn(II) in CadC. We propose that a glycine residue was ancestral whether the repressor binds Zn(II) at a Site 2 like CadC or has no Site 2 like the paralogous ArsR and implies that acquisition of regulatory ability in SmtB was a more recent evolutionary event.

    The potential risk by being exposed by artificial UV-sources at the workplace in Austria was measured and evaluated. A representative overview of the measurement results, the evaluation of the UV-exposure risk and recommendations to reduction of the risk is given. The international organizations ACGIH and ICNIRP have promulgated guidelines on exposure to ultraviolet radiation (UVR), to protect the general public and workers from hazards which result from being exposed to UVR sources. As the two guidelines differ in some definitions of the exposure duration to calculate the radiant exposure, different results may be obtained. Further it is possible to use the concept of minimal erythema doses - MED's in order to analyze the ability of UV radiation to produce erythema in the human skin. The differences have been analyzed by using the ICNIRP and ACGIH guidelines and the concept of MED's. The different results were compared and discussed. Measurements of UV-radiation concerning photobiological hazards were perfor...

    Full Text Available Ziel: Es bestehen zunehmend Hinweise, daß dem Rhabdosphinkter eine zentrale Rolle im Rahmen des Kontinenzmechanismus, insbesondere nach radikaler Prostatektomie, zukommt. Gleichzeitig besteht jedoch unverändert Unklarheit über dessen genaue anatomische Ausdehnung und die Art der Muskelfasern, weshalb die vorliegende Studie, unter spezieller Berücksichtigung der Anatomie und Muskelfaserzusammensetzung, durchgeführt wurde. Material und Methode: Der Rhabdosphinkter am Autopsiepräparat von 10 Foeten (3 weiblich, 7 männlich und 5 männlichen Erwachsenen sowie 15 Prostatektomiepräparaten bei Patienten mit Prostatakarzinom wurden konventionell mittels Masson-Trichrom und Hematoxylin-Eosin sowie immunohistochemisch mittels Antikörper gegen die langsamen und schnellen quergestreiften Muskelfasern untersucht. Ergebnisse: Im menschlichen foetalen Rhabdosphinkter beträgt das Verhältnis von schnellen zu langsamen quergestreiften Muskelfasern 2 zu 1 zu Gunsten der schnellen quergestreiften Muskelfasern. Beim Erwachsenen hingegen kommt es zu einer Umkehr dieses Verhältnisses zu Gunsten der langsamen Muskelfasern in einem Verhältnis von 1 zu 4. Der männliche Rhabdosphinkter weist einen charakteristischen Hauptbestandteil im Bereich der Pars membranacea der Harnröhre mit einer dorsalen Muskellücke gegen die Denonvillier'sche Faszie hin auf. Er verdünnt sich gegen rostral und infiltriert die Prostata in 3 bis 4 klar unterscheidbaren Muskelfaserbündeln, die im Bereich des vorderen Blasenhalses enden. Diskussion: Nach der Geburt kommt es beim Menschen zur Ausbildung eines kontinenten Sphinktermechanismus unter zunehmender neuronaler Kontrolle durch das zentrale Nervensystem. Das anatomische Korrelat im unteren Harntrakt stellt die veränderte Muskelfaserzusammensetzung der quergestreiften Muskelfasern des Rhabdosphinkters dar.

    Energy Technology Data Exchange (ETDEWEB)

    Madsen, M M; Wilmot, E L; Taylor, J M

    1983-02-01

    RADTRAN II is a flexible analytical tool for calculating both the incident-free and accident impacts of transporting radioactive materials. The consequences from incident-free shipments are apportioned among eight population subgroups and can be calculated for several transport modes. The radiological accident risk (probability times consequence summed over all postulated accidents) is calculated in terms of early fatalities, early morbidities, latent cancer fatalities, genetic effects, and economic impacts. Groundshine, inhalation, direct exposure, resuspension, and cloudshine dose pathways are modeled to calculate the radiological health risks from accidents. Economic impacts are evaluated based on costs for emergency response, cleanup, evacuation, income loss, and land use. RADTRAN II can be applied to specific scenario evaluations (individual transport modes or specified combinations), to compare alternative modes or to evaluate generic radioactive material shipments. Unit-risk factors can easily be evaluated to aid in performing generic analyses when several options must be compared with the amount of travel as the only variable.

    There are currently nine power reactors in operation in Germany. These are exclusively light-water reactors (seven pressurised water reactors and two boiling water reactors whose fuel assemblies are composed of low-enriched uranium oxide or uranium/plutonium mixed oxide (MOX)). With the 13{sup th} amendment to the Atomic Energy Act of 6 August 2011 as a consequence of the events in Japan, which led to a reassessment of the risks associated with the use of nuclear energy, the licences to operate the Biblis A and B, Neckarwestheim 1, Brunsbuettel, Isar 1, Unterweser, Philippsburg 1 and Kruemmel plants expired. For the remaining nine nuclear power plants, the operating licences will expire between 2015 and the end of 2022. Another 12 power reactors have already been or are in the process of being decommissioned. There were furthermore seven prototype and demonstration nuclear power plants operated in Germany, which have all been decommissioned. Two of these, the HDR Grosswelzheim, which was fully removed in 1998, and the VAK Kahl, which was also removed completely in 2010, were boiling water reactors using low-enriched uranium oxide pellets (in the VAK partly also MOX) as fuel. Two other reactors, the AVR at Juelich and the THTR at Hamm-Uentrop, were helium-cooled graphite-moderate high-temperature reactors in which the medium- and high-enriched fuel consisting of uranium/thorium oxide particles was enclosed in graphite spheres. The MZFR at Karlsruhe was a heavy-water reactor using very-low-enriched (0.85 %) uranium oxide fuel. The Compact Sodium-Cooled Nuclear Reactor (Kompakter Natriumgekuehlter Kernreaktor - KNK II) at Karlsruhe used high-enriched uranium oxide and uranium/plutonium mixed-oxide fuel. The Niederaichbach NPP (KKN) was in operation between 1972 and 1974 as a prototype plant with a heavy-water-moderated and CO{sub 2}-gas-cooled pressure tube reactor using natural uranium as fuel. Its complete removal was finished in 1995; the reactor was released from

    In the research project on the ''Review and development of safety-related assessments of disposal facilities with negligible heat generation; development and provision of the necessary set of tools, using the example of the Konrad disposal facility'' (3612R03410), the state of the art in science and technology of the safety-related assessments and sets of tools for building a safety case was examined. The reports pertaining to the two work packages described the further development of the methodology for accident analyses (WP 1) and of building a safety case (WP 2); also, comparisons were drawn on a national and international scale with the methods applied in the licensing procedure of the Konrad disposal facility. A safety case as well as its underlying analyses and methods always has to be brought up to date with the development of the state of the art in science and technology. In Germany, two safety cases regarding the long-term safety of disposal facilities have been prepared. These are the licensing documentation for the Konrad disposal facility in the year 1990 and the research project regarding the preliminary safety case for the Gorleben site (Vorlaeufige Sicherheitsanalyse Gorleben - VSG) in the year 2013, both reflecting the state of development of building a safety case at the respective time. Comparing the two above-mentioned examples of safety cases and taking recent international recommendations and national regulations into account, this report on Work Package 2 presents the development of the international state of the art in science and technology. This has been done by summarising the essential differences and similarities of each element of the safety case for the Konrad disposal facility on the one hand and the VSG and the international status on the other hand.

  20. Evaluation of the computerized procedures Manual II (COPMA II)

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the effects of a computerized procedure system, the Computerized Procedure Manual II (COPMA-II), on the performance and mental workload of licensed reactor operators. To evaluate COPMA-II, eight teams of two operators were trained to operate a scaled pressurized water reactor facility (SPWRF) with traditional paper procedures and with COPMA-II. Following training, each team operated the SPWRF under normal operating conditions with both paper procedures and COPMA-II. The teams then performed one of two accident scenarios with paper procedures, but performed the remaining accident scenario with COPMA-II. Performance measures and subjective estimates of mental workload were recorded for each performance trial. The most important finding of the study was that the operators committed only half as many errors during the accident scenarios with COPMA-II as they committed with paper procedures. However, time to initiate a procedure was fastest for paper procedures for accident scenario trials. For performance under normal operating conditions, there was no difference in time to initiate or to complete a procedure, or in the number of errors committed with paper procedures and with COPMA-II. There were no consistent differences in the mental workload ratings operators recorded for trials with paper procedures and COPMA-II

    Until now, it was generally accepted that clean electric arc furnace charge materials generate lower steelmaking emissions. In Sept. 1994 and July 1995 BSW conducted nine test programs involving different charge materials and different off-gas treatment process in order to show that charge materials have no influence on emissions. The result of the scientific investigation shows that dioxin and furan emissions are lowered by cooling process applied to the gases evacuated from the furnace. The continuation of this fundamental research should be preferred over secondary measures which simply transfer dioxins and furans to the collected dust. (orig.) [Deutsch] Bei der Elektrostahlherstellung ging man bisher davon aus, dass nur sauberes Einsatzmaterial geringe Emissionen erzeugt. Da die BSW aufgrund experimenteller Erfahrungen die Ansicht vertreten hat, dass nicht allein das Einsatzmaterial einen Einfluss auf die Emissionen hat, wurden im September 1994 und im Juli 1995 neun Messkampagnen mit unterschiedlichen Einsatzstoffen und unterschiedlichen Abgasbehandlungsverfahren durchgefuehrt. Das Ergebnis der wissenschaftlichen Untersuchung bestaetigt, dass die Dioxin- und Furanemissionen vor allem durch das Abkuehlverfahren der direkt abgesaugten Abgase reduziert werden. Die Weiterentwicklung dieser Grundlagenforschung sollte den Sekundaermassnahmen, die lediglich eine Verlagerung der Dioxine und Furane in den abgeschiedenen Staub darstellen, vorgezogen werden. Die Untersuchungen zeigen, dass ein Emissionswert bei Dioxinen und Furanen <0,1 ng TE/Nm{sup 3} bei diesen Anlagen erreicht werden kann. (orig.)

  3. Inside ISIS II

    1981-01-01

    ISIS stands for Identification of Secondaries by Ionization Sampling. It was a drift chamber with an active volume of about 40 m3 built by Oxford University as a particle identifier for the European Hybrid Spectrometer (EHS). The photo shows the electrostatic grading structure and the central anode-wire plane, with Roger Giles standing just under it (Annual Report 1981 p. 57, Fig. 4). ISIS-II differed from the prototype ISIS-I only in the depth of the track (4 m instead of 1 m) thus extending the momentum range for particle identification to 50 GeV/c. See Nucl. Instr. and Meth. 224 (1984) 396, and Nucl. Instr. and Meth. 258 (1987) 26.

    The SkyTrough DSP will advance the state-of-the-art in parabolic troughs for utility applications, with a larger aperture, higher operating temperature, and lower cost. The goal of this project was to develop a parabolic trough collector that enables solar electricity generation in the 2020 marketplace for a 216MWe nameplate baseload power plant. This plant requires an LCOE of 9¢/kWhe, given a capacity factor of 75%, a fossil fuel limit of 15%, a fossil fuel cost of $6.75/MMBtu, $25.00/kWht thermal storage cost, and a domestic installation corresponding to Daggett, CA. The result of our optimization was a trough design of larger aperture and operating temperature than has been fielded in large, utility scale parabolic trough applications: 7.6m width x 150m SCA length (1,118m2 aperture), with four 90mm diameter × 4.7m receivers per mirror module and an operating temperature of 500°C. The results from physical modeling in the System Advisory Model indicate that, for a capacity factor of 75%: The LCOE will be 8.87¢/kWhe. SkyFuel examined the design of almost every parabolic trough component from a perspective of load and performance at aperture areas from 500 to 2,900m2. Aperture-dependent design was combined with fixed quotations for similar parts from the commercialized SkyTrough product, and established an installed cost of $130/m2 in 2020. This project was conducted in two phases. Phase I was a preliminary design, culminating in an optimum trough size and further improvement of an advanced polymeric reflective material. This phase was completed in October of 2011. Phase II has been the detailed engineering design and component testing, which culminated in the fabrication and testing of a single mirror module. Phase II is complete, and this document presents a summary of the comprehensive work.

  5. Formation of Mixed Ligand Complexes of Ni(II), Pd(II), and Pt(II)

    International Nuclear Information System (INIS)

    The stability constants of binary and ternary Ni(II), Pd(II), and Pt(II)complexes containing salicylidine-3-amino-1,2,4 triazole schiff base (L1) and a second ligand, cysteine (L2) in a 1:1:1 molar ratio were determined pH-metrically at different temperatures (25C, 30C, 35C, 40C) in 50% (v/v) aqueous EtOH at an ionic strength I=0.1M (NaCl). The stability constants of the mono and mixed ligand complexes of Ni(II), Pd(II), and Pt(II) have been evaluated. The difference in stability constants, M(Schiffbase) M logK logK-logK M M(Schiffbase)(Cys)M(Cys) is found to be positive, showing a cooperative behavior of the ligands. Thermodynamic parameters H and S are calculated for systems controlled by variation in temperatures. (author)

  6. Synthesis and characterization of nickel(II), chromium(III), cobalt(II), copper(II), zinc(II), and cadmium(II) complexes with isatin- isonicotinoylhydrazone

    International Nuclear Information System (INIS)

    A few metal complexes of isatin-isonicotinoylhydrazone with Ni(II), Cr(III), Co(II), Cu(II), Zn(II) and Cd(II) have been prepared and characterized on the basis of elemental analyses, infrared and electronic spectra as well as 1H NMR spectra, conductivity and magnetic measurements. In view of the results obtained, it has been found that two molecules of isatin-isonicotinoylhydrazone are chelated to the central metal ion as bis-uninegative ONO tridentate ligand forming non-electrolytic octahedral metal complexes.

Some intermediate complexes have been isolated by temperature arrest technique (pyrolysis) and characterised. Configurational and conformational changes have been studied by elemental analyses, IR and electronic spectra, magnetic moment data (in the case of Ni(II) and Cu(II) complexes) and thermal analysis. Ea*, ΔH, and ΔS for the decomposition reaction of these complexes are evaluated and the stability of the complexes with respect to activation energy has also been compared. The linear correlation has been found between Ea* and ΔS for the decomposition of the complexes. (author)

    Carnitine palmitoyltransferase II (CPT-II) has a crucial role in the β-oxidation of long-chain fatty acids in mitochondria. We report here the crystal structure of rat CPT-II at 1.9 Å resolution. The overall structure shares strong similarity to those of short- and medium-chain carnitine acyltransferases, although detailed structural differences in the active site region have a significant impact on the substrate selectivity of CPT-II. Three aliphatic chains, possibly from a detergent that is used for the crystallization, were found in the structure. Two of them are located in the carnitine and CoA binding sites, respectively. The third aliphatic chain may mimic the long-chain acyl group in the substrate of CPT-II. The binding site for this aliphatic chain does not exist in the short- and medium-chain carnitine acyltransferases, due to conformational differences among the enzymes. A unique insert in CPT-II is positioned on the surface of the enzyme, with a highly hydrophobic surface. It is likely that this surface patch mediates the association of CPT-II with the inner membrane of the mitochondria. PMID:16781677

    2003-08-01

    Full Text Available Neurofibromatosis type 2 (NF2 is an inherited disease which is mainly characterized by the development of multiple schwannomas and meningiomas.  Incidence of the disease is about 1 in 60,000. Affected individuals inevitably develop schwannomas, typically affecting both auditory-vestibular nerve which lead in hearing loss and deafness. The majority of patients present with hearing loss, which is usually unilateral at onset and may be accompanied or preceded by tinnitus. Vestibular schwannomas may also cause dizziness or imbalance as a first symptom. Nausea, vomiting or true vertigo are rare symptoms, except in late-stage disease. NF II is caused by a defect in the gene that normally gives rise to a product called Merlin or Schwannomin, located on chromosome 22. Diagnosis is based on clinical and neuroimaging studies. Presymptomatic genetic testing is an integral part of the management of NF2 families. Prenatal diagnosis and pre-implantation genetic diagnosis is possible.

  13. Can Co(II) or Cd(II) substitute for Zn(II) in zinc fingers?

    P Rabindra Reddy; M Radhika

    2001-02-01

    Zinc finger domains consist of sequences of amino acids containing cysteine and histidine residues tetrahedrally coordinated to a zinc ion. The role of zinc in a DNA binding finger was considered purely structural due to the absence of redox chemistry in zinc. However, whether other metals e.g. Co(II) or Cd(II) can substitute Zn(II) is not settled. For an answer the detailed interaction of Co(II) and Cd(II) with cysteine methylester and histidine methylester has been investigated as a model for the zinc core in zinc fingers. The study was extended to different temperatures to evaluate the thermodynamic parameters associated with these interactions. The results suggest that zinc has a unique role.

    The Options Study has been conducted for the purpose of evaluating the potential of alternative integrated nuclear fuel cycle options to favorably address the issues associated with a continuing or expanding use of nuclear power in the United States. The study produced information that can be used to inform decisions identifying potential directions for research and development on such fuel cycle options. An integrated nuclear fuel cycle option is defined in this study as including all aspects of the entire nuclear fuel cycle, from obtaining natural resources for fuel to the ultimate disposal of used nuclear fuel (UNF) or radioactive wastes. Issues such as nuclear waste management, especially the increasing inventory of used nuclear fuel, the current uncertainty about used fuel disposal, and the risk of nuclear weapons proliferation have contributed to the reluctance to expand the use of nuclear power, even though it is recognized that nuclear power is a safe and reliable method of producing electricity. In this Options Study, current, evolutionary, and revolutionary nuclear energy options were all considered, including the use of uranium and thorium, and both once-through and recycle approaches. Available information has been collected and reviewed in order to evaluate the ability of an option to clearly address the challenges associated with the current implementation and potential expansion of commercial nuclear power in the United States. This Options Study is a comprehensive consideration and review of fuel cycle and technology options, including those for disposal, and is not constrained by any limitations that may be imposed by economics, technical maturity, past policy, or speculated future conditions. This Phase II report is intended to be used in conjunction with the Phase I report, and much information in that report is not repeated here, although some information has been updated to reflect recent developments. The focus in this Options Study was to

    Full Text Available

    The dynamics of a stiffnite are here inferred. A stiffnite is a sheet-shaped, gravity-driven submarine sediment flow, with a fabric made up of marine ooze. To infer stiffnite dynamics, order of magnitude estimations are used. Field deposits and experiments on materials taken from the literature are also used. Stiffnites can be tens or hundreds of kilometers wide, and a few centimeters/ meters thick. They move on the sea slopes over hundreds of kilometers, reaching submarine velocities as high as 100 m/s. Hard grain friction favors grain fragmentation and formation of triboelectrically electrified particles and triboplasma (i.e., ions + electrons. Marine lipids favor isolation of electrical charges. At first, two basic assumptions are introduced, and checked a posteriori: (a in a flowing stiffnite, magnetic dipole moments develop, with the magnetization proportional to the shear rate. I have named those dipoles as Ambigua. (b Ambigua are ‘vertically frozen’ along stiffnite streamlines. From (a and (b, it follows that: (i Ambigua create a magnetic field (at peak, >1 T. (ii Lorentz forces sort stiffnite particles into two superimposed sheets. The lower sheet, L+, has a sandy granulometry and a net positive electrical charge density. The upper sheet, L–, has a silty muddy granulometry and a net negative electrical charge density; the grains of sheet L– become finer upwards. (iii Faraday forces push ferromagnetic grains towards the base of a stiffnite, so that a peak of magnetic susceptibility characterizes a stiffnite deposit. (iv Stiffnites harden considerably during their motion, due to magnetic confinement. Stiffnite deposits and inferred stiffnite characteristics are compatible with a stable flow behavior against bending, pinch, or other macro instabilities. In the present report, a consistent hypothesis about the nature of Ambigua is provided.

    In order to clarify the chemical behaviour of Americium in saline aqueous systems relevant for final storage this study deals with the chemical reactions of trivalent and pentavalent Americium in NaCl-solutions under the influence of radiolysis from its own alpha radiation. The focus of the study was on investigating the geologically relevant reactions, such as hydrolysis or carbonate- and chloride complexing in solid-liquid equilibriums. Comprehensive measurements on solubility and spectroscopic studies in NaCl-solutions were carried out in a CO{sub 2}-free atmosphere and 10{sup -2} atm CO{sub 2} partial pressure. Identification and characterisation of the AM (III) and AM(V) solid phases were supplemented by structural research with the chemically analogue EU (III) and Np(V) compounds. The alpha-radiation induced radiolysis in saline NaCl solutions and the redox behaviour of Americium which was influenced thereby were spectroscopically quantified. (orig.)

    A new tridentate ligand incorporating a monoxime and thiosemi-carbozone moieties has been synthesized. Its copper(II), nickel(II) and palladium(II) complexes have been prepared and characterized by physical and spectral methods. Elemental analyses and spectroscopic data of the metal complexes are consistent with the formation of a mononuclear copper(II) complex and binuclear complex with both nickel(II) and palladium(II). In the copper(II) complex the fourth coordination site is occupied by nitrate ion. In the binculear complexes the fourth coordination site is occupied by the deprotonated oxime oxygen of the ligand coordinated to the other metal

    Purpose: In the state of North Rhine-Westphalia (NRW), Germany, a survey was conducted on radiologic examinations ordered by general practitioners (GPs). Part II of this study aims to determine the quality of the process and outcome. The reference standard is the assessment of both radiologists and physicians without board certification in radiology working at a university hospital and in outpatient facilities. Materials and Methods: All GPs in NRW were asked to cooperate. Participating GPs filled out a questionnaire for each patient. The patients recorded the symptoms prompting the imaging examinations. The radiologists or other physicians performing the examinations were asked to provide the images and written reports and to complete a questionnaire. A file was created for each of the 394 patients with image documentation of at least one examination. Each file, which included medical history, physical findings, imaging documentation and written report, was sequentially forwarded to a board-certified radiologist and to a physician without board certification in radiology working in a university hospital and in an outpatient facility. All physicians were requested to complete a structured questionnaire for each file. Results: The referral diagnoses were rated as medically plausible in 81%, the indications for imaging found correct in 76%, the examination techniques considered appropriate in 69%, the clinical question answered in 63%, the interpretation judged medically correct in 50% and all incidental findings documented in 49%. In retrospect, 32% of the examinations were judged superfluous. The sequence of multiple examinations performed on a particular patient was rated as appropriate in 51%. The interpretation revealed specialty-related differences. The plausibility of the referral diagnoses had a significant impact on the appropriateness of subsequent diagnostic investigations. Marked deficits showed sonography, performance by non-radiologists, self

    Two symptomatic patients with heterozygous carnitine palmitoyltransferase II (CPT II) deficiency are reported. Patient 1, a 21-year-old female professional tennis player, suffered from exercise-induced attacks of muscle pain, burning sensations and proximal weakness. Patient 2, a 30-year-old male amateur marathon runner developed muscle cramps and rhabdomyolysis upon extensive exercise and insolation-induced fever. In both patients, the common p.S113L mutation was found in heterozygote state. No second mutation could be found upon sequencing of all the exons of CPT2 gene including exon-intron boundaries. Biochemically, residual CPT activity in muscle homogenate upon inhibition by malonyl-CoA and Triton-X-100 was intermediate between controls and patients with mutations on both alleles. Although CPT II deficiency is an autosomal recessive disorder, the reported patients indicate that heterozygotes might also have typical attacks of myalgia, pareses or rhabdomyolysis. PMID:23184072

    1. Objectives To produce a validation database out of those recorded signals it will be necessary also to identify the documents need to reconstruct the status of reactor at the time of the beginning of the recordings. This should comprehends the core loading specification (assemblies type and location and burn-up) along with this data the assemblies drawings and the core drawings will be identified. The first task of the project will be identify the location of the sensors, with respect the reactor plant layout, and the physical quantities recorded by the Experimental Breeder Reactor-II (EBR-II) data acquisition system. This first task will allow guiding and prioritizing the selection of drawings needed to numerically reproduce those signals. 1.1 Scopes and Deliverables The deliverables of this project are the list of sensors in EBR-II system, the identification of storing location of those sensors, identification of a core isotopic composition at the moment of the start of system recording. Information of the sensors in EBR-II reactor system was summarized from the EBR-II system design descriptions listed in Section 1.2.

  14. Proposed MIDAS II processing array

    Energy Technology Data Exchange (ETDEWEB)

    Meng, J.

    1982-03-01

    MIDAS (Modular Interactive Data Analysis System) is a ganged processor scheme used to interactively process large data bases occurring as a finite sequence of similar events. The existing device uses a system of eight ganged minicomputer central processor boards servicing a rotating group of 16 memory blocks. A proposal for MIDAS II, the successor to MIDAS, is to use a much larger number of ganged processors, one per memory block, avoiding the necessity of switching memories from processor to processor. To be economic, MIDAS II must use a small, relatively fast and inexpensive microprocessor, such as the TMS 9995. This paper analyzes the use of the TMS 9995 applied to the MIDAS II processing array, emphasizing computational, architectural and physical characteristics which make the use of the TMS 9995 attractive for this application.

  16. Minimal type II seesaw model

    International Nuclear Information System (INIS)

    We propose a minimal type II seesaw model by introducing only one right-handed neutrino besides the SU(2)L triplet Higgs to the standard model. In the usual type II seesaw models with several right-handed neutrinos, the contributions of the right-handed neutrinos and the triplet Higgs to the CP asymmetry, which stems from the decay of the lightest right-handed neutrino, are proportional to their respective contributions to the light neutrino mass matrix. However, in our minimal type II seesaw model, this CP asymmetry is just given by the one-loop vertex correction involving the triplet Higgs, even though the contribution of the triplet Higgs does not dominate the light neutrino masses. For illustration, the Fritzsch-type lepton mass matrices are considered

  17. Radiochemical extraction and separation of mercury(II) from zinc(II) and cadmium(II) with cyanex 471X

    International Nuclear Information System (INIS)

    The extraction of zinc(II), cadmium(II) and mercury(II) from thiocyanate solutions has been investigated by tracer techniques with triisobutylphosphine sulfide (= TIBPS, commercially known as CYANEX 471X) in benzene as an extractant. The extraction data have been analyzed by both graphical and theoretical methods taking into account aqueous phase speciation and all plausible complexes extracted into the organic phase. These results demonstrate that Hg(II) is extracted into benzene as Hg(SCN)2 and Hg(SCN)2.3 TIBPS. On the other hand, under the present experimental conditions, Zn(II) and Cd(II) are not found to be extracted into benzene with TIBPS. These results also demonstrate the selective separation possibility of Hg(II) from Zn(II) and Cd(II) with TIBPS as an extractant from aqueous solutions containing thiocyanate. (orig.)

    Bauer, Nicole

    2015-04-27

    In the present work the complexation of Cm(III), Eu(III) and Am(III) with human serum transferrin is studied. The aim of this work was the identification and the spectroscopic and thermodynamic characterization of An(III) and Ln(III) transferrin complex species. Different speciation methods, such as time-resolved laser fluorescence spectroscopy (TRLFS), luminescence spectroscopy and EXAFS (Extended X-Ray Absorption Fine Structure) spectroscopy were applied. Using TRLFS two unambiguously different Cm(III) transferrin species were identified for the first time. In the pH range from 3.5 to 9.7 the Cm(III) transferrin species I is formed revealing complexation of the metal ion at a nonspecific site of the protein surface. In case of the Cm(III) transferrin species II Cm(III) is bound at the Fe(III) binding site of the protein resulting in a 4-fold coordination via amino acid groups of the protein (His, Asp, 2 x Tyr) and coordination of two water molecules and three additional ligands, e.g. OH{sup -} or CO{sub 3}{sup 2-}. Due to the kinetic and thermodynamic differences of the binding sites of the N- and C-lobe, the experimental conditions ensure exclusive coordination of Cm(III) at the C-terminal binding site. In addition to the complexation studies of Cm(III) with transferrin, the interaction with the recombinant N-lobe of human serum transferrin (hTf/2N) as a model component for the transferrin N-lobe was investigated. At pH≥7.4 a Cm(III) hTf/2N species with Cm(III) bound at the Fe(III) binding site is formed which is comparable to the Cm(III) transferrin species II. An increase of the temperature from room temperature (T=296 K) to physiological temperature (T=310 K) favors the complexation of Cm(III) with both transferrin and hTf/2N. The complexation of Cm(III) with transferrin was investigated at three different carbonate concentrations (c(carbonate){sub tot}=0 mM, 0,23 mM und 25 mM (physiological carbonate concentration)). An increase of the total carbonate

    Full Text Available Archivierende Bibliotheken kämpfen spätestens seit Beginn des 20. Jahrhunderts mit wiederkehrenden Platzproblemen. Eine Lösung zeichnet sich seit Mitte des Jahrhunderts mit der Schaffung von Speicherbibliotheken ab. Sie konzentrieren aufzubewahrende Bestände an sicheren Orten. Eine andere Lösung sind Regelungen, die viele teilnehmende Bibliotheken verpflichten, bestimmte Titel sicher und langfristig aufzubewahren – sie verteilen Bestände auf viele Orte. Der folgende Beitrag stellt, nach einem kurzen Blick in die Geschichte von Speicherbibliotheken, das Projekt „Kooperative Speicherbibliothek Schweiz“, das sechs Bibliotheken der deutschsprachigen Schweiz realisieren, sowie das Projekt „Kooperative Print-Archivierung“ (KPA der Konferenz der Universitätsbibliotheken der Schweiz (KUB vor. Since the beginning of the 20th century, libraries with archival responsibilities have been challenged by collection growth and diminishing space. One solution for this challenge has been realised in the creation of central storage libraries which store collections safely. Another potential solution could be agreements made between libraries to store specific volumes on a long term basis at different premises. The following article presents two ongoing projects in Switzerland: the “Kooperative Speicherbibliothek Schweiz” which involves six libraries in the German speaking part of the country, and the “Kooperative Print-Archivierung” which was launched by the Konferenz der Universitätsbibliotheken der Schweiz (KUB. Les bibliothèques patrimoniales sont confrontées au moins depuis le début du XXe siècle à des problèmes de place récurrents. Une solution a été trouvée au milieu du siècle avec la création des bibliothèques dépôts. Celles-ci permettent la préservation des collections en un seul lieu sûr. Une alternative consiste à établir des conventions obligeant les bibliothèques partenaires à conserver certains ouvrages de manière durable et de répartir ainsi géographiquement les collections. Après un bref résumé de l’histoire des bibliothèques dépôts, cet article présente le projet de la Kooperative Speicherbibliothek Schweiz (Bibliothèque dépôt coopérative de Suisse, réalisé par six bibliothèques de Suisse alémanique, ainsi que le projet de Coopération en archivage des périodiques imprimés (CAP de la Conférence des bibliothèques universitaires suisses (CBU.

    This report documents the history of the major buildings in Sandia National Laboratories` Technical Area II. It was prepared in support of the Department of Energy`s compliance with Section 106 of the National Historic Preservation Act. Technical Area II was designed and constructed in 1948 specifically for the final assembly of the non-nuclear components of nuclear weapons, and was the primary site conducting such assembly until 1952. Both the architecture and location of the oldest buildings in the area reflect their original purpose. Assembly activities continued in Area II from 1952 to 1957, but the major responsibility for this work shifted to other sites in the Atomic Energy Commission`s integrated contractor complex. Gradually, additional buildings were constructed and the original buildings were modified. After 1960, the Area`s primary purpose was the research and testing of high-explosive components for nuclear weapons. In 1994, Sandia constructed new facilities for work on high-explosive components outside of the original Area II diamond-shaped parcel. Most of the buildings in the area are vacant and Sandia has no plans to use them. They are proposed for decontamination and demolition as funding becomes available.

  3. DECOVALEX II PROJECT Executive Summary

    International Nuclear Information System (INIS)

    DECOVALEX II project started in November 1995 as a continuation of the DECOVALEX I project, which was completed at the end of 1994. The project was initiated by recognising the fact that a proper evaluation of the current capacities of numerical modelling of the coupled T-H-M processes in fractured media is needed not only for small scale, well controlled laboratory test cases such as those studied in DECOVALEX I, but also for less characterised, more complex and realistic in-situ experiments. This executive summary presents the motivation, structure, objectives, approaches, and highlights of the main tasks and main achievements of the DECOVALEX II project from 1995-1999. The main source of the materials came from four technical reports the project prepared by the project Secretariat, which, in turn, were based on numerous progress reports produced by a large number of international research teams over the three and half year period. The editors of this summary, together with the Steering Committee of the DECOVALEX II project, feel very encouraged by the progresses which have been made during the project time and very positive about the usefulness of the achievements reached by the project to the larger international community of scientific research and management of radioactive wastes in different countries. We sincerely hope that continued efforts be made to forward the research carried out in both DECOVALEX I and DECOVALEX II projects so that the disposal of radioactive waste could be managed on a more reliable scientific basis

  4. Radioimmunologic determination of plasmapepsinogen II

    International Nuclear Information System (INIS)

    Within the frame of this study the pepsinogen II concentration could be determined for the first time with a radioimmunoassay in the plasma. In our normal study group the mean value was 13.91 ng/ml with a variation between 4.08 and 36.19 ng/ml. With increasing patient age a continuous increase of this concentration could be observed. The mean value of 14.99 ng/ml for male patients was by 4.75 ng/ml higher than the mean value of 10.24 ng/ml for female patients. The 24 hour profiles represented for the pepsinogen plasma concentration daily physiologic fluctuations and a stabilisation at night. The effects of meals could not be defined unambiguously. In stimulation tests Pentagastrin provoked in 4 of 9 test persons an increase of the concentration of up to 70% of the basic value. In short-term stress-tests the Pg II concentrations found in the test subjects presented an increase or a decrease. In investigations before or after the same patient underwent an operative procedure, an expressive Pg II decrease (up to 33.74 ng/ml) could be detected. Patients with a total resection of the stomach had only a very low Pg II concentration (less than 3.1 ng/ml). In patients with gastric pathologies a significant difference of the confidence limits was found for the Pg II concentration between superficial gastritis (m = 16.04 ng/ml) and atrophic gastritis (m = 27.38 ng/ml). Compared with various gastric diseases the normal patient group presents a significant difference with reference to the atrophic gastritis or the cancerous stomach. The mean values found in atrophic gastritis or the cancerous stomach. The mean values found in atrophic gastritis and in gastric carcinoma are close to each other and are increased, compared to those measured in the normal patient group. (orig./MG)

    A series of Co(II), Ni(II), Cu(II), Cd(II), Zn(II) and Hg(II) complexes have been synthesized with newly synthesized Schiff base derived from naphthofuran-2-carbohydrazide and cinnamaldehyde. The elemental analyses of the complexes are confined to the stoichiometry of the type MLCl2 [M = Co(II) and Cu(II)], ML2Cl2 [M = Ni(II), Cd(II), Zn(II) and Hg(II)] respectively, where L is Schiff base ligand. Structures have been proposed from elemental analyses, IR, electronic, mass, 1H NMR, ESR spectral data, magnetic, and thermal studies. The measured low molar conductance values in DMF indicate that the complexes are non-electrolytes. Spectroscopic studies suggest coordination occurs through azomethine nitrogen and carbonyl oxygen of the ligand with the metal ions. The Schiff base and its complexes have been screened for their antibacterial (Escherichia coli, Staphylococcus aureus, Bacillus subtilis and Salmonella typhi) and antifungal (Aspergillus niger, Aspergillus flavus, Cladosporium and Candida albicans) activities by minimum inhibitory concentration (MIC) method. The DNA cleavage studies by agarose gel electrophoresis method was studied for all the complexes.

    International Nuclear Information System (INIS)

    Currently, the TGV collaboration is investigating the two-neutrino double electron capture (2vEC/EC) of 106Cd at the Modane underground laboratory. The study is performed with low-background multi-HPGe detector TGV II, which has been constructed for measurements of the rare processes. The half-life limits of T1/2>2.6x1020 years(for Phase I, 8687 hours) and T1/2>3.6x1020 years(for Phase II, 9003 hours) were obtained for the ground state to ground state 2vEC/EC of 106Cd. The results already allow to rule out some of the previous nuclear structure calculations.

    Full Text Available The complexes of Mn(II, Co(II, Ni(II, Cu(II and Zn(II with 3,4,5-trimethoxybenzoic acid anion of the formula: M(C10H11O52·nH2O, where n = 6 for Ni(II, n = 1 for Mn(II, Co(II, Cu(II, and n = 0 for Zn, have been synthesized and characterized by elemental analysis, IR spectroscopy, X–ray diffraction measurements, thermogravimetry and magnetic studies. They are crystalline compounds characterized by various symmetry. They decompose in various ways when heated in air to 1273 K. At first, they dehydrate in one step and form anhydrous salts. The final products of decomposition are oxides of the respective metals (Mn2O3, Co3O4, NiO, CuO, ZnO. The solubilities of the analysed complexes in water at 293 K are in the orders of 10-2 – 10-4 mol dm-3. The magnetic susceptibilities of the Mn(II, Co(II, Ni(II and Cu(II complexes were measured over the range of 76–303 K and the magnetic moments were calculated. The results show that the 3,4,5-trimethoxybenzoates of Mn(II, Co(II and Ni(II are high-spin complexes but that of Cu(II forms a dimer [Cu2(C10H11O54(H2O2]. The carboxylate groups bind as monodentate or bidentate chelating or bridging ligands.

    Mn(II), Co(II), Ni(II) and Cu(II) complexes are synthesized with thiosemicarbazone (L) derived from pyrrole-2-carboxyaldehyde. These complexes are characterized by elemental analysis, molar conductance, magnetic susceptibility measurement, mass, IR, electronic and EPR spectral studies. The molar conductance measurement of the complexes in DMSO indicates that the complexes are non-electrolyte except Co(L) 2(NO 3) 2 and Ni(L) 2(NO 3) 2 complexes which are 1:2 electrolyte. All the complexes are of high-spin type. On the basis of spectral studies an octahedral geometry may be assigned for Mn(II), Co(II) and Ni(II) complexes except Co(L) 2(NO 3) 2 and Ni(L) 2(NO 3) 2 which are of tetrahedral geometry. A tetragonal geometry may be suggested for Cu(II) complexes.

    Even shortly after World War II, as large amounts of ultrapure rare earths (RE) became available for scientific research, a large reservoir of peculiar phenomena was uncovered. These had not been investigated before or were completely unknown. Examples of these phenomena are, magnetic ordering, the KONDO effect, quantum critical points, heavy fermion behaviour, as well as superconductivity. A strong influence of small variations of the chemical composition on the physical properties had been observed. The main focus of the present thesis is the detailed elucidation of the crystal structure of fundamental representatives of this class of substances, as well as the influence of dedicated variations of the chemical composition on their structure and properties. In particular, the characterisation of modulated crystals is an important facet. A large spectrum of physical methods, especially X-ray diffraction, is employed in the investigations. Results on oriented intergrowth in the Y-Ni-B-C system, incommensurately ordered vacancies in the Ce-Si system, incorporation of stacking faults as well as commensurately ordered transition metal atoms (TM) in the RE-TM-Si system and site specific occupancy in the Y-Mn-Fe-O system are presented. Their elucidation is reported for the first time. It is shown which consequences the structural peculiarities will have on the physical properties. An objective of this thesis is to give an overview of the possible ''answers'' that can be obtained with regard to the influence of the crystal structure of rare earth transition metal compounds on deviations of the chemical composition.

    The latest result of the CHARM II experiment is presented. A determination of the neutral current coupling constants gVe and gAe from a study of the differential cross sections of (anti)muon-neutrino electron scattering. The analysis is based on data taken in the years 1987 to 1990 with the CHARM II detector which was exposed to the CERN wide band neutrino beam. A total of about 2100 νe and 2200 ν-bare scattering events were observed. Comparing the distributions of kinematic variables of these events to the predicted distributions the effective vector and axial-vector neutral current coupling constants of the electron are determined to be gVe=-0.025±0.019 and gAe=-0.503±0.018.

    The Belle II experiment at the SuperKEKB collider in Japan is designed to indirectly probe new physics using approximately 50 times the data recorded by its predecessor. An accurate determination of the decay-point position of subatomic particles such as beauty and charm hadrons as well as a precise measurement of low-momentum charged particles will play a key role in this pursuit. These will be accomplished by a vertex detector, which comprises two layers of pixelated silicon detector and four layers of silicon vertex detector. We describe herein the design, prototyping and construction efforts of the Belle-II silicon vertex detector that is aimed to be commissioned towards the middle of 2017.

    Full Text Available Background: Heavy metals have been recognized as harmful environmental pollutant known to produce highly toxic effects on different organs and systems of both humans and animals. The aim of this paper is to evaluate the adsorption potential of chitosan for the removal of Pb(II, Fe(II and Cu(II ions from aqueous solutions. Methods: This study was conducted in laboratory scale. In this paper chitosan has been used as an adsorbent for the removal of Pb(II, Fe(II and Cu(II from aqueous solution. In batch tests, the effects of parameters like pH solution (1.0-8.0, initial metal concentrations (100-1000 mgL-1, contact time (5.0-150 min and adsorbent dose (1.0-7.0 g on the adsorption process were studied. Results: The results showed that the adsorption of Pb(II, Fe(II and Cu(II ions on chitosan strongly depends on pH. The experimental isothermal data were analyzed using the Langmuir and Freundlich equations and it was found that the removal process followed the Langmuir isotherm and maximum adsorption capacity for the adsorption of Pb(II, Fe(II and Cu(II ions by the chitosan were 55.5mg g−1, 71.4 mg g−1 and 59 mg g−1, respectively, under equilibrium conditions at 25±1 ºC. The adsorption process was found to be well described by the pseudo-second-order rate model. Conclusion: The obtained results showed that chitosan is a readily, available, economic adsorbent and was found suitable for removing Pb(II, Fe(II and Cu(II ions from aqueous solution.

    Citrus essential oils are widely used in the food, cosmetics, and pharmaceutical industries, so the determination of heavy metals content is of great importance to guarantee their quality. The present work deals with the quantification of Cd(II), Cu(II), Pb(II), and Zn(II) in different varieties of citrus essential oils, using derivative potentiometric stripping analysis. Two different metals extraction procedures, involving concentrated hydrochloric acid treatment and acid-alcoholic dissolution, are tested on lemon, mandarin, sweet orange, and bergamot essential oils, and they give very similar results. Cd(II), Cu(II), Pb(II), and Zn(II) recovery tests spanned from 95 to 100.50%, providing evidence that metals quantification remained unaffected by the cleanup steps of the two procedures. The repeatability of the hydrochloric acid extraction method, applied on different varieties of essential oils, is >95.00% for Cd(II), Cu(II), Pb(II), and Zn(II), whereas the repeatability of the acid-alcoholic dissolution method is >93.00% for Cu and Cd only in lemon oil. Detection limits obtained for the four analytes, using both procedures, ranged from 0.10 to 0.98 ng g(-)(1) in lemon, mandarin, sweet orange, and bergamot essential oils. PMID:12590445

Urotensin II (UII is an 11 amino acid peptide that stimulates its’ obligatory G protein coupled urotensin II receptors (UT to modulate cardiovascular function in humans and in other animal species, and has been implicated in both vasculoprotective and vasculopathic effects. For example, tissue and circulating concentrations of UII have been reported to increase in some studies involving patients with atherosclerosis, heart failure, hypertension, preeclampsia, diabetes, renal disease and liver disease, raising the possibility that the UT receptor system is involved in the development and/or progression of these conditions. Consistent with this hypothesis, administration of UT receptor antagonists to animal models of cardiovascular disease have revealed improvements in cardiovascular remodelling and hemodynamics. However, recent studies have questioned this contributory role of UII in disease, and have instead postulated a protective effect on the cardiovascular system. For example, high concentrations of circulating UII correlated with improved clinical outcomes in patients with renal disease or myocardial infarction.

    PEP-II is a two-ring asymmetric B factory operating at the Upsilon(4S) resonance. It was constructed by a SLAC-LBNL-LLNL collaboration. The collider comprises two rings, a High-Energy Ring (HER) storing 9 GeV electrons, and a Low-Energy Ring (LER) storing 3.1 GeV positrons. Commissioning of the HER began in mid-1997 and commissioning of the LER began in mid-1998. First evidence for collisions was obtained on July 23, 1998. The BaBar detector was installed in early 1999, and commissioning with the detector commenced in May 1999. By September 1999, PEP-II had reached a peak luminosity of 1.35 x 10{sup 33} cm{sup {minus}2} s{sup {minus}1}. In the present run, which began in October 1999, the peak luminosity has reached 3.1 x 10{sup 33} cm{sup {minus}2} s{sup {minus}1} and the integrated luminosity delivered is 25 fb{sup {minus}1}. At present, PEP-II is the world's highest luminosity collider. In this paper we describe the startup experience and summarize the operational experience during fiscal year 2000 (from October 1999 through September 2000). Plan s for luminosity upgrades are briefly described.

Potentiometric stripping analysis (PSA was used to determine the content of Cd(II, Cu(II, Mn(II, Pb(II, and Zn(II in bird tissues. For toxic metals, the highest levels of Pb were in liver and those of Cd in lung; Zn levels were higher than Cu and Mn in all tissues analyzed. The concentrations in liver, lung, kidney, and muscle could be considered as an indicative of chronic exposure to metals while the presence of metals in skin could be consequential to storing and elimination processes. The found concentrations of metals in the studied matrices required a highly sensitive method for their determination and a simple sample preparation procedure, and the proposed method was well suited for this purpose.

    Here we present the synthesis of the new Mn(II), Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) complexes with chelating ligand (Z)-(2-((1,3-diphenyl-1H-pyrazol-4-yl)methylene) hydrazinyl)(pyridin-2-ylamino)methanethiol. All the complexes were characterized by elemental analysis, IR, (1)H NMR, UV-vis, magnetic susceptibility measurements and EPR spectral studies. IR spectra of complexes showed that the ligand behaves as NN neutral bidentate, NSN mononegative tridentate and NSNN mononegative tetradentate. The electronic spectra and the magnetic measurements suggested the octahedral geometry for all complexes as well as the EPR confirmed the tetragonal distorted octahedral for Cu(II) complex. Cd(II) complex showed the highest inhibitory antioxidant activity either using ABTS method. The SOD-like activity exhibited those Cd(II) and Zn(II) complexes have strong antioxidative properties. We tested the synthesized compounds for antitumor activity and showed that the ability to kill liver (HePG2) and breast (MCF-7) cancer cells definitely. PMID:24727176

  17. Collision strengths for [O II] and [S II

    International Nuclear Information System (INIS)

    Collision strengths and parameters UPSILON (i → j) required for the calculation of collisional rate coefficients are calculated for the fine-structure transitions 2Dsub(3/2)-2Dsub(5/2), 2Psub(1/2)-2Psub(3/2), 4Ssub(3/2)-2Dsub(J), 4Ssub(3/2)-2Psub(J) and 2Dsub(J)-2Psub(J), within the ground configuration of [O II]. The complicated resonance structure in the 2Dsub(3/2)-2Dsub(5/2) collision strength above the 2D threshold is taken into account. The collision strengths are obtained from reactance matrices calculated by Pradhan using the close-coupling approximation. Distorted-wave and close-coupling calculations are made for the forbidden transitions in the ground configuration of [S II]. The target is represented by the ground configuration, 3s23p3, plus the quasi-degenerate configuration 3p5, which gives some correlation effect. The present close-coupling results confirm the essentially similar calculation of Conneely, Smith and Lipsky, and the present distorted-wave results are in good agreement with the close-coupling results but are not in agreement with the earlier distorted wave calculations of Czyzak and Krueger.

  18. PEP-II Hardware Reliability

    International Nuclear Information System (INIS)

    Hardware reliability takes on special importance in large accelerator facilities intended to work as factories; i.e., when they are expected to deliver design performance for extended periods of time. The PEP-II B-Factory at SLAC is such a facility. In this paper, we summarize PEP-II reliability statistics from the first four years of production running. The four running periods extended from January 12 through October 31, 2000, from February 4, 2001 through June 30, 2002, from November 15, 2002 through June 30, 2003, and from September 9, 2003 through July 31, 2004. These four periods are designated Runs 1, 2, 3, and 4 in the discussion and tables presented in the paper. The first four runs encompassed 30,359 hours. During this time, PEP-II was delivering luminosity to the BaBar detector 57.9 percent of the time. In addition, 5.3 percent of the time was used for scheduled dedicated machine development work, and 4.5 percent was scheduled off for maintenance, installations, or safety checks. Injection and tuning accounted for 19.9 percent. The remaining 12.4 percent was lost due to malfunctions. During this time period, a total of 9701 malfunctions were reported, but most did not interrupt the running program. The unscheduled down time, a total of 3883 hours, was attributed to 1724 of these malfunctions. Mean Time to Fail (MTTF) and Mean Time to Repair (MTTR) are presented for each of the major subsystems, and long-term availability trends are discussed

    Asymmetric B factories, PEP-II with BaBar and KEKB with Belle, made a decisive contribution to flavour physics. In addition, they also observed a long list of new hadrons, some of which do not fit into the standard meson and baryon schemes. The next generation of B factories, the so called Super B factory will search for departures from the Standard model. For this task, a 50 times larger data sample is needed, corresponding to an integrated luminosity of 50 ab{sup −1}. With such a large data sample there are many more topics to explore, including searches for new and exotic hadrons, and investigation of their properties.

    NSLS-II, the new 3rd generation light source at BNL was designed for a brightness of 1022 photons s-1mm-2mrad-2 (0.1%BW)-1. It was constructed between 2009 and 2014. The storage ring was commissioned in April 2014 which was followed by insertion device and beamline commissioning in the fall of 2014. All ambitious design parameters of the facility have already been achieved except for commissioning the full beam intensity of 500mA which requires more RF installation. This paper reports on the results of commissioning.

  2. SHRIMP II analysis of minerals

    International Nuclear Information System (INIS)

    Full text: Ion microprobes are specialised mass spectrometers that allow in situ isotopic and abundance measurements of chemically complex materials with a spatial resolution of 5 to 20 micrometers. The Sensitive High mass Resolution Ion Micro-Probe (SHRIMP II), an Australian built instrument, is designed to achieve high mass resolution (>5000 MRP at the 1% level) and great sensitivity, with detection limits in the ppb range for most elements in the Periodic Table. The SHRIMP ion microprobes have revolutionised geochronology and they are primarily used for U-Th-Pb dating of zircons from geological samples. The in situ analysis capability of the SHRIMP is now recognised as the best method for obtaining highly precise ages for zircons and other accessory minerals in ancient rocks with complex geological histories. The Western Australian SHRIMP II, which is located at Curtin University, provides rapid, precise measurements of isotope ratios in minerals and glasses and has been applied to a wide variety of geological problems and to a few applied physics problems. During the last three years we have expanded the number of minerals that can be used for U-Th-Pb age dating to include titanite, rutile, apatite, badellyite, perovskite and monazite. In addition to age dating the SHRIMP can be used for isotopic tracing. SHRIMP analysis provides the spatial resolution required to study S isotopes in very complex ores from many of Australia's largest ore deposits (Mt Isa, Broken Hill, Olympic Dam). Sulphur isotope ratios can be measured with a precision of 1-2 ppm in both sulphides and sulphates. In situ S isotopic compositions of galena (PbS), sphalerite (ZnS), chalcopyrite (CuS) and pyrite (FeS) has been crucial in the development of models of ore deposition. The in situ analytical capability and the high sensitivity of the SHRIMP II has allowed measurement of, diffusion profiles of REE and other trace element in melt couples, the mineral-melt partition coefficients of these

  3. TRIGA Mark II benchmark experiment

    International Nuclear Information System (INIS)

    The experimental results of startup tests after reconstruction and modification of the TRIGA Mark II reactor in Ljubljana are presented. The experiments were performed with a completely fresh, compact, and uniform core. The operating conditions were well defined and controlled, so that the results can be used as a benchmark test case for TRIGA reactor calculations. Both steady-state and pulse mode operation were tested. In this paper, the following steady-state experiments are treated: critical core and excess reactivity, control rod worths, fuel element reactivity worth distribution, fuel temperature distribution, and fuel temperature reactivity coefficient

    The Belle detector at the KEKB electron-positron collider has collected almost 1 billion Y(4S) events in its decade of operation. Super-KEKB, an upgrade of KEKB is under construction, to increase the luminosity by two orders of magnitude during a three-year shutdown, with an ultimate goal of 8E35 /cm^2 /s luminosity. To exploit the increased luminosity, an upgrade of the Belle detector has been proposed. A new international collaboration Belle-II, is being formed. The Technical Design Report presents physics motivation, basic methods of the accelerator upgrade, as well as key improvements of the detector.

    .) [German] Zielsetzung: Untersuchung der Volumenaenderungen und der intraaneurysmatischen Druckbelastungen bei kompletter Aneurysmaausschaltung und in Endoleaks, bei Normotonie und arterieller Hypertonie. Material und Methoden: Bei 36 Mischlingshunden wurde ein experimentelles Aortenaneurysma aus autologem Material operativ erzeugt und mittels Stentgrafts behandelt. Bei 18 Faellen wurden die aortalen Seitenaeste waehrend der Operation ligiert (Gruppe I). Bei den verbliebenen 18 Faellen wurden die aortalen Seitenaeste erhalten (Gruppe II); sie waren nach endovaskulaerer Aneurysmatherapie Ursache von Typ-II-Endoleaks. Die Aneurysmavolumina wurden prae- und postinterventionell sowie eine Woche, 6 Wochen und 6 Monate nach endovaskulaerer Therapie aus dem CT-Datensatz volumentiert. Am Ende des Follow-up erfolgten Druckmessungen im ausgeschalteten Aneurysmasack (Gruppe I und II), selektiv in Endoleaks (Gruppe II) und intravasal zur Referenzmessung. Die Druckkurven und dp/dtmax wurden simultan aus diesen drei Positionen abgeleitet. Der Quotient aus Aneurysmadruck und intraaortalem Referenzdruck wurde zur Beschreibung der Druckuebertragung in den Aneurysmasack berechnet. Ergebnisse: Im Vergleich zu Gruppe I zeigten Aneurysmen mit offenen Seitenarterien (Gruppe II) nach endovaskulaerer Therapie in allen Faellen Typ-II-Endoleaks. Die Verlaufsuntersuchungen ergaben eine bessere Aneurysmarueckbildung in Gruppe I: Volumenaenderung nach einer Woche, 6 Wochen und 6 Monaten +0,08%, -1,62% und -9,76% (Median, Gruppe I) gegenueber +1,43%, +0,67%, -4,04% (Gruppe II), p<0,05. Bei kompletter Aneurysmaausschaltung (Gruppe I) zeigte sich eine zunehmende Druckentlastung des Aneurysmas im Verlauf. Der Quotient aus systolischem Aneurysmadruck und intravasalem Referenzdruck betrug nach einer Woche, 6 Wochen und 6 Monaten im Median 0,662, 0,576 und 0,385. Der korrespondierende Quotient aus dp/dtmax im Aneurysma und dem intravasalem Referenzwert betrug 0,12, 0,07 und 0,04. Innerhalb von Endoleaks

  6. Theory of function spaces II

    CERN Document Server

    Triebel, Hans

    1992-01-01

    Theory of Function Spaces II deals with the theory of function spaces of type Bspq and Fspq as it stands at the present. These two scales of spaces cover many well-known function spaces such as Hölder-Zygmund spaces, (fractional) Sobolev spaces, Besov spaces, inhomogeneous Hardy spaces, spaces of BMO-type and local approximation spaces which are closely connected with Morrey-Campanato spaces. Theory of Function Spaces II is self-contained, although it may be considered an update of the author’s earlier book of the same title. The book’s 7 chapters start with a historical survey of the subject, and then analyze the theory of function spaces in Rn and in domains, applications to (exotic) pseudo-differential operators, and function spaces on Riemannian manifolds. ------ Reviews The first chapter deserves special attention. This chapter is both an outstanding historical survey of function spaces treated in the book and a remarkable survey of rather different techniques developed in the last 50 years. It is s...

  7. ERB-II operating experience

    International Nuclear Information System (INIS)

    As originally designed and operated, EBR-II successfully demonstrated the concept of a sodium-cooled fast breeder power plant with a closed fuel reprocessing cycle (mini-nuclear park). Subsequent operation has been as an irradiation facility, a role which will continue into the foreseeable future. Since the beginning of operation in 1961, operating experience of EBR-II has been very satisfactory. Most of the components and systems have performed well. In particular, the mechanical performance of heat-removal systems has been excellent. A review of the operating experience reveals that all the original design objectives have been successfully demonstrated. To date, no failures or incidents resulting in serious in-core or out-of-core consequences have occurred. No water-to-sodium leaks have been detected over the life of the plant. At the present time, the facility is operating very well and continuously except for short shutdowns required by maintenance, refueling, modification, and minor repair. A plant factor of 76.9% was achieved for the calendar year 1976

  8. BNL ATF II beamlines design

    International Nuclear Information System (INIS)

    The Brookhaven National Laboratory. Accelerator Test Facility (BNL ATF) is currently undergoing a major upgrade (ATF-II). Together with a new location and much improved facilities, the ATF will see an upgrade in its major capabilities: electron beam energy and quality and CO2 laser power. The electron beam energy will be increased in stages, first to 100-150 MeV followed by a further increase to 500 MeV. Combined with the planned increase in CO2 laser power (from 1-100 TW), the ATF-II will be a powerful tool for Advanced Accelerator research. A high-brightness electron beam, produced by a photocathode gun, will be accelerated and optionally delivered to multiple beamlines. Besides the energy range (up to a possible 500 MeV in the final stage) the electron beam can be tailored to each experiment with options such as: small transverse beam size (<10 um), short bunch length (<100 fsec) and, combined short and small bunch options. This report gives a detailed overview of the ATFII capabilities and beamlines configuration.

    2012-01-01

    The spectrum of singly-ionized iron (Fe II) has been recorded using high-resolution Fourier transform and grating spectroscopy over the wavelength range 900 {\\AA} to 5.5 {\\mu}m. The spectra were observed in high-current continuous and pulsed hollow cathode discharges using Fourier transform (FT) spectrometers at the Kitt Peak National Observatory, Tucson, AZ and Imperial College, London and with the 10.7 m Normal Incidence Spectrograph at the National Institute of Standards and Technology. Roughly 12 900 lines were classified using 1027 energy levels of Fe II that were optimized to measured wavenumbers. The wavenumber uncertainties of lines in the FT spectra range from 10-4 cm-1 for strong lines around 4 {\\mu}m to 0.05 cm-1 for weaker lines around 1500 {\\AA}. The wavelength uncertainty of lines in the grating spectra is 0.005 {\\AA}. The ionization energy of (130 655.4+-0.4) cm-1 was estimated from the 3d6(5D)5g and 3d6(5D)6h levels.

  14. Interactions of tetracycline with Cd (II), Cu (II) and Pb (II) and their cosorption behavior in soils

    International Nuclear Information System (INIS)

    Tetracycline (TC), a common antibiotic, can behave as an efficient ligand with cations, but the effect of its interaction with heavy metal cations on the mobility of both species in soils has not been well evaluated. In this study, the complexation affinities of TC with Cd (II), Cu (II) and Pb (II) were examined using potentiometric titration and spectroscopic methods. The cosorption behavior of TC and metal ions onto three selected Chinese soils was evaluated using batch adsorption experiments. The presence of metal cations promoted TC adsorption through an ion bridging effect in the order Cu (II) > Pb (II) > Cd (II), which is in accordance with their complexation ability with TC. The addition of TC affects metal adsorption differently depending on the solution pH and metal type. Therefore, it is necessary to consider the complexation ability of TC and divalent metal cations when evaluating their mobility in soils. -- Highlights: •The complex affinity with TC has an order of Cu(II) > Pb(II) > Cd(II). •The complexation constants of TC with the three metals are obtained. •The cosorption behavior in soils greatly depends on the complexation affinity. -- The interaction between tetracycline and metal cations can influence the adsorption behavior of these species in soils, depending on their complexation ability

    Full Text Available When the compounds are heated in an inert atmosphere it can be verified the consecutive partial sublimation, fusion, partial volatilization and partial thermal decomposition of the anhydrous complexes. When in an oxidating atmosphere the above process is only verified to Cu(II chelates. Anhydrous copper(II complexes present a monoclinic structure in the b form and the volatilized compound in a a form. Zinc(II and cadmium(II hydrated complexes are isomorphous and they present different cell dimensions from those reported previously.

    DNA topoisomerase II is an essential enzyme in eukaryotes and is required for many aspects of DNA metabolism including DNA replication, recombination, chromosome segregation and chromosome condensation. It is also a major component of the nuclear scaffold. Topoisomerase II from lower eukaryotes has been shown to be phosphorylated in vivo and this phosphorylation leads to a modulation of activity. However, unlike these lower eukaryotes, human topoisomerase II exists as two c...

  19. A cryogenic system for TIBER II

    International Nuclear Information System (INIS)

    Phase II of the Tokamak Ignition/Burn Experimental Reactor (TIBER II) study describes one option for a small, economical, next-generation tokamak. Because of its small size, minimum shielding is used between the plasma and the toroidal-field (TF) coils. Consequently, a large cryogenic system (approximately 70 kW at 4.5 K) capable of delivering forced-flow helium is required. This paper describes a cryogenic system that meets this requirement and includes TIBER-II requirements

    CERN Document Server

    Tang, Yuping; Guo, Yicheng; Kurk, Jaron

    2014-01-01

    We report on a study of the 2300-2600\\AA FeII/FeII* multiplets in the rest-UV spectra of star-forming galaxies at 1.01.5 \\AA and of the FeII* emission lines to W_r>0.5 \\AA. Whenever we can measure the systemic redshift of the galaxies from the [OII] emission line, we find that both the FeII and MgII absorption lines are blueshifted, indicative that both species trace gaseous outflows. We also find, however, that the FeII gas has generally lower outflow velocity relative to that of MgII. We investigate the variation of FeII line profiles as a function of the radiative transfer properties of the lines, and find that transitions with higher oscillator strengths are more blueshifted in terms of both line centroids and line wings. We discuss the possibility that FeII lines are suppressed by stellar absorptions. The lower velocities of the FeII lines relative to the MgII doublet, as well as the absence of spatially extended FeII* emission in 2D stacked spectra, suggest that most clouds responsible for the FeII abso...

  1. Cu(II) and Zn(II) ions alter the dynamics and distribution of Mn(II) in cultured chick glial cells

    International Nuclear Information System (INIS)

    Previous studies revealed that Mn(II) is accumulated in cultured glial cells to concentrations far above those present in whole brain or in culture medium. The data indicated that Mn(II) moves across the plasma membrane into the cytoplasm by facilitated diffusion or counter-ion transport with Ca(II), then into mitochondria by active transport. The fact that 1-10 microM Mn(II) ions activate brain glutamine synthetase makes important the regulation of Mn(II) transport in the CNS. Since Cu(II) and Zn(II) caused significant changes in the accumulation of Mn(II) by glia, the mechanisms by which these ions alter the uptake and efflux of Mn(II) ions has been investigated systematically under chemically defined conditions. The kinetics of [54MN]-Mn(II) uptake and efflux were determined and compared under four different sets of conditions: no adducts, Cu(II) or Zn(II) added externally, and with cells preloaded with Cu(II) or Zn(II) in the presence and absence of external added metal ions. Zn(II) ions inhibit the initial velocity of Mn(II) uptake, increase total Mn(II) accumulated, but do not alter the rate or extent Mn(II) efflux. Cu(II) ions increase both the initial velocity and the net Mn(II) accumulated by glia, with little effect on rate or extent of Mn(II) efflux. These results predict that increases in Cu(II) or Zn(II) levels may also increase the steady-state levels of Mn(II) in the cytoplasmic fraction of glial cells, which may in turn alter the activity of Mn(II)-sensitive enzymes in this cell compartment

    Purpose: Experimental and clinical data suggest a reduction of radiation-induced acute toxicity by amifostine. We investigated this issue in a randomized trial comparing radiochemotherapy (RCT) versus radiochemotherapy and amifostine (RCT+A) in patients with head and neck cancer. Patients and methods: Forty-seven patients with pharyngeal or laryngeal cancer (T{sub 1-2}N{sub 1-2}G{sub 3},T{sub 3-4}N{sub 0-2}G{sub 1-3}) were randomized to receive RCT alone (21 patients) or RCT+A (21 patients). Patients were irradiated up to 60 Gy (R{sub 0}) or 70 Gy (R{sub 1/2}). Chemotherapy consisted of 70 mg/m{sup 2} carboplatin and was administered over 5 days in the 1st and 5th week of the radiotherapy course. 250 mg amifostine were applied daily just before each radiotherapy session. Acute toxicity was evaluated according to the Common Toxicity Criteria (CTC). As for xerostomia no patients with laryngeal cancer were assessed because in these cases only small volumes of the salivary glands were within the treatment volume. To evaluate the overall toxicity a summarized CTC score of all observed side effects was calculated. Results: Forty-two patients were evaluable. Clinical characteristics (age, sex, Karnofsky index, tumor-staging) were well balanced in both treatment groups. Amifostine provided reduction in xerostomia and mucositis. Conclusions: According to our preliminary results amifostine has a radioprotective effect on salivary glands. Mucositis can be reduced during radiochemotherapy. At this point of patient accrual the difference between both groups are statistically not significant. To improve the radioprotective effects of amifostine in clinical practice the application of a higher dose (>250 mg) seems to be necessary. (orig.)

  10. SWAMI II technology transfer plan

    International Nuclear Information System (INIS)

    Thousands of drums of radioactive/hazardous/mixed waste are currently stored at DOE sites throughout US; they are stored in warehouse facilities on an interim basis, pending final disposition. Recent emphasis on anticipated decommissioning of facilities indicates that many more drums of waste will be generated, requiring additional storage. Federal and state regulations dictate that hazardous waste covered by RCRA be inspected periodically for container degradation and to verify inventories. All known DOE waste storage facilities are currently inspected manually. A system to perform robotic inspection of waste drums is under development by the SRTC Robotics Group of WSRC; it is called the Stored Waste Autonomous Mobile Inspector (SWAMI). The first version, SWAMI I, was developed by the Savannah River Technology Center (SRTC) as a proof of principle system for autonomous inspection of drums in a warehouse. SWAMI I was based on the Transitions Research Corporation (TRC) HelpMate mobile robot. TRC modified the Helpmate to navigate in aisles of drums. SRTC added subsystems to SWAMI I to determine its position in open areas, read bar code labels on the drums up to three levels high, capture images of the drums and perform a radiation survey of the floor in the aisles. The radiation survey was based on SRTC patented technology first implemented on the Semi-Intelligent Mobile Observing Navigator (SIMON). The radiation survey is not essential for the inspection of drums, but is an option that can increase the utility and effectiveness of SWAMI in warehouses with radioactive and/or mixed waste. All the sensors on SWAMI I were fixed on the vehicle. From the success of SWAMI I, a second version, SWAMI II, was developed; it will be evaluated at Fernald and tested with two other mobile robots. Intent is to transfer the technology developed for SWAMI I and II to industry so that it can supply additional units for purchase for drum inspection

    Polluted and contaminated water can often contain more than one heavy metal species. It is possible that the behavior of a particular metal species in a solution system will be affected by the presence of other metals. In this study, we have investigated the adsorption of Cd(II), Cu(II), Pb(II), and Zn(II) onto basic oxygen furnace slag (BOF slag) in single- and multi-element solution systems as a function of pH and concentration, in a background solution of 0.01 M NaNO{sub 3}. In adsorption edge experiments, the pH was varied from 2.0 to 13.0 with total metal concentration 0.84 mM in the single element system and 0.21 mM each of Cd(II), Cu(II), Pb(II), and Zn(II) in the multi-element system. The value of pH{sub 50} (the pH at which 50% adsorption occurs) was found to follow the sequence Zn > Cu > Pb > Cd in single-element systems, but Pb > Cu > Zn > Cd in the multi-element system. Adsorption isotherms at pH 6.0 in the multi-element systems showed that there is competition among various metals for adsorption sites on BOF slag. The adsorption and potentiometric titrations data for various slag-metal systems were modeled using an extended constant-capacitance surface complexation model that assumed an ion-exchange process below pH 6.5 and the formation of inner-sphere surface complexes at higher pH. Inner-sphere complexation was more dominant for the Cu(II), Pb(II) and Zn(II) systems.

    In this study, Nostoc commune (cyanobacterium) was used as an inexpensive and efficient biosorbent for Cd(II) and Zn(II) removal from aqueous solutions. The effect of various physicochemical factors on Cd(II) and Zn(II) biosorption such as pH 2.0-7.0, initial metal concentration 0.0-300 mg/L and contact time 0-120 min were studied. Optimum pH for removal of Cd(II) and Zn(II) was 6.0, while the contact time was 30 min at room temperature. The nature of biosorbent and metal ion interaction was evaluated by infrared (IR) technique. IR analysis of bacterial biomass revealed the presence of amino, carboxyl, hydroxyl, and carbonyl groups, which are responsible for biosorption of Cd(II) and Zn (II). The maximum biosorption capacities for Cd(II) and Zn(II) biosorption by N. commune calculated from Langmuir biosorption isotherm were 126.32 and 115.41 mg/g, respectively. The biosorption isotherm for two biosorbents fitted well with Freundlich isotherm than Langmuir model with correlation coefficient (r{sup 2} < 0.99). The biosorption kinetic data were fitted well with the pseudo-second-order kinetic model. Thus, this study indicated that the N. commune is an efficient biosorbent for the removal of Cd(II) and Zn(II) from aqueous solutions. (Copyright copyright 2011 WILEY-VCH Verlag GmbH and Co.

  20. Multi-Nuclear NMR Investigation of Nickel(II), Palladium(II), Platinum(II) and Ruthenium(II) Complexes of an Asymmetrical Ditertiary Phosphine

    International Nuclear Information System (INIS)

    Complexes synthesized by reacting alkyl and aryl phosphines with different transition metals are of great interest due to their catalytic properties. Many of the phosphine complexes are soluble in polar solvents as a result they find applications in homogeneous catalysis. In our present work we report, four transition metal complexes of Ni(II), Pd(II), Pt(II) and Ru(II) with an asymmetrical ditertiaryphosphine ligand. The synthesized ligand bears a less electronegative substituent such as methyl group on the aromatic nucleus hence makes it a strong σ-donor to form stable complexes and thus could effectively used in catalytic reactions. The complexes have been completely characterized by elemental analyses, FTIR, 1HNMR, 31PNMR and FAB Mass Spectrometry methods. Based on the spectroscopic evidences it has been confirmed that Ni(II), Pd(II) and Pt(II) complexes with the ditertiaryphosphine ligand showed cis whereas the Ru(II) complex showed trans geometry in their molecular structure

    Heteroleptic complexes of zinc(II), copper(II), manganese(II), and cobalt(II) of the types [MLL′(H2O)2]·nH2O and [MLL′]·nH2O have been synthesized using sodium N-methyl-N-phenyldithiocarbamate (L) and benzoylacetone (L′). The metal complexes were characterized by elemental analysis, electrical conductance, magnetic susceptibility, infrared (IR), and UV-visible spectroscopic studies. The electrical conductance measurements revealed the nonelectrolytic nature of the synthesized complexes. The results of the elemental analyses, magnetic susceptibility measurements, and electronic spectra inferred that the Zn(II) complex adopted a four-coordinate geometry while the Co(II), Cu(II), and Mn(II) complexes assumed octahedral geometries. The IR spectra showed that the metal ions coordinated with the ligands via the S- and O-donor atoms. The geometry, electronic, and thermodynamic parameters of the complexes were obtained from density functional theory (DFT) calculations. The spin density distributions, relative strength of H–bonds, and thermodynamic parameters revealed that the order of stability of the metal complexes is Mn Zn. The agar diffusion methods were used to study the antimicrobial activity of the complexes against two Gram positive bacteria (S. aureus and S. pneumoniae), one Gram negative bacterium (E. coli), and two fungi organisms (A. niger and A. candida) and the complexes showed a broad spectrum of activities against the microbes.

    Hepcidin is a peptide hormone that regulates the homeostasis of iron metabolism. The N-terminal domain of hepcidin is conserved amongst a range of species and is capable of binding Cu(II) and Ni(II) through the amino terminal copper-nickel binding motif (ATCUN). It has been suggested that the binding of copper to hepcidin may have biological relevance. In this study we have investigated the binding of Cu(II) with model peptides containing the ATCUN motif, fluorescently labelled hepcidin and hepcidin using MALDI-TOF mass spectrometry. As with albumin, it was found that tetrapeptide models of hepcidin possessed a higher affinity for Cu(II) than that of native hepcidin. The log K 1 value of hepcidin for Cu(II) was determined as 7.7. Cu(II) binds to albumin more tightly than hepcidin (log K 1 = 12) and in view of the serum concentration difference of albumin and hepcidin, the bulk of kinetically labile Cu(II) present in blood will be bound to albumin. It is estimated that the concentration of Cu(II)-hepcidin will be less than one femtomolar in normal serum and thus the binding of copper to hepcidin is unlikely to play a role in iron homeostasis. As with albumin, small tri and tetra peptides are poor models for the metal binding properties of hepcidin. PMID:26883683

    Complexes synthesized by reacting alkyl and aryl phosphines with different transition metals are of great interest due to their catalytic properties. Many of the phosphine complexes are soluble in polar solvents as a result they find applications in homogeneous catalysis. In our present work we report, four transition metal complexes of Ni(II), Pd(II), Pt(II) and Ru(II) with an asymmetrical ditertiaryphosphine ligand. The synthesized ligand bears a less electronegative substituent such as methyl group on the aromatic nucleus hence makes it a strong σ-donor to form stable complexes and thus could effectively used in catalytic reactions. The complexes have been completely characterized by elemental analyses, FTIR, {sup 1}HNMR, {sup 31}PNMR and FAB Mass Spectrometry methods. Based on the spectroscopic evidences it has been confirmed that Ni(II), Pd(II) and Pt(II) complexes with the ditertiaryphosphine ligand showed cis whereas the Ru(II) complex showed trans geometry in their molecular structure.

    Full Text Available This work reports the application of a straw ash from barley as a novel bioadsorbent for the removal of several heavy metals: Ni(II, Cd(II, Cu(II, and Co(II. Equilibrium and kinetic models for heavy metals sorption were developed by considering the effect of the contact time, initial heavy metal ion concentrations, effect of temperature, and initial pH. The adsorption of heavy metal ions have been studied in terms of pseudo-first- and -second-order kinetics, and the Freundlich, Langmuir and Langmuir–Freundlich isotherms models have also been used to the equilibrium adsorption data. The equilibrium data fitted well with the Langmuir–Freundlich model and showed the following affinity order of the material: Ni(II>Cu(II>Co(II>Cd(II. The adsorption kinetics followed the mechanism of the pseudo-second-order equation for all systems studied, confirming chemical sorption as the rate-limiting step of adsorption mechanisms. The thermodynamic parameters (ΔG°, ΔH° and ΔS° indicated that the adsorption of heavy metals ions were feasible, spontaneous and endothermic at 15–80 °C.

    Metallothionein (MT)-I+II synthesis is induced in the central nervous system (CNS) in response to practically any pathogen or disorder, where it is increased mainly in reactive glia. MT-I+II are involved in host defence reactions and neuroprotection during neuropathological conditions, in which MT......-I+II decrease inflammation and secondary tissue damage (oxidative stress, neurodegeneration, and apoptosis) and promote post-injury repair and regeneration (angiogenesis, neurogenesis, neuronal sprouting and tissue remodelling). Intracellularly the molecular MT-I+II actions involve metal ion control and...... neurons by signal transduction through the low-density lipoprotein family of receptors on the cell surface involving lipoprotein receptor-1 (LRP1) and megalin (LRP2). In this review we discuss the newest data on cerebral MT-I+II functions following brain injury and experimental autoimmune...

  18. TRUPACT-II, a regulatory perspective

    International Nuclear Information System (INIS)

    The Transuranic Package Transporter II (TRUPACT-II) is a US Nuclear Regulatory Commission (NRC) certified Type B packaging for the shipment of contact-handled transuranic (CH-TRU) material by the US Department of Energy (DOE). The NRC approved the TRUPACT-II design as meeting the requirements of Title 10, Code of Federal Regulations, Part 71 (10 CFR 71) and issued Certificate of Compliance (CofC) Number 9218 to the DOE. There are currently 15 certified TRUPACT-IIs. Additional TRUPACT-IIs will be required to make more than 15,000 shipments of CH-TRU waste to the Waste Isolation Pilot Plant (WIPP) site near Carlsbad, New Mexico. The TRUPACT-II may also be used for the DOE inter-site and intra-site shipments of CH-TRU waste. The Land Withdrawal Act (Public Law 102-579), enacted by the US Congress, October 30, 1992, and an agreement between the DOE and the State of New Mexico, signed August 4, 1987, both stipulate that only NRC approved packaging may be used for shipments of TRU waste to the WIPP. Early in the TRUPACT-II development phase it was decided that the transportation system (tractor, trailer, and TRUPACT-II) should be highway legal on all routes without the need for oversize and/or overweight permits. In large measure, public acceptance of the DOE's efforts to safely transport CH-TRU waste depends on the public's perception that the TRUPACT-II is in compliance with all applicable regulations, standards, and quality assurance requirements. This paper addresses some of the numerous regulations applicable to Type B packaging, and it describes how the TRUPACT-II complies with these regulations

    2012-01-01

    Full Text Available The sorption of lead, cadmium and zinc ions from aqueous solution by Lagenaria vulgaris shell biosorbent (LVB in batch system was investigated. The effect of relevant parameters such as contact time, biosorbent dosage and initial metal ions concentration was evaluated. The Pb(II, Cd(II and Zn(II sorption equilibrium (when 98% of initial metal ions were sorbed was attained within 15, 20 and 25 min, respectively. The pseudo first, pseudo-second order, Chrastil’s and intra-particle diffusion models were used to describe the kinetic data. The experimental data fitted the pseudo-second order kinetic model and intra-particle diffusion model. Removal efficiency of lead(II, cadmium(II and zinc(II ions rapidly increased with increasing biosorbent dose from 0.5 to 8.0 g dm-3. Optimal biosorbent dose was set to 4.0 g dm-3. An increase in the initial metal concentration increases the sorption capacity. The sorption data of investigated metal ions are fitted to Langmuir, Freundlich and Temkin isotherm models. Langmuir model best fitted the equilibrium data (r2 > 0.99. Maximal sorption capacities of LVB for Pb(II, Cd(II and Zn(II at 25.0±0.5°C were 0.130, 0.103 and 0.098 mM g-1, respectively. The desorption experiments showed that the LVB could be reused for six cycles with a minimum loss of the initial sorption capacity.

    1991-03-01

    By means of classical interference spectroscopy, using enriched isotope samples, the isotope shift between178Hf and180Hf has been measured for 33 transitions in the Hf II spectrum. For the pure Russell-Saunders terms 5 d 26 s 4 F and2 F the parametric analysis yields a field-shift difference of 17(2) mK produced by the second-order interaction of the electrostatic operator and the field-shift operator. Semi-empirical calculations based on the non-relativistic Hartree-Fock method reproduce this value as well as the experimental field shifts if a factor of 1.68(6) is used to scale the ab initio electron densities at the nucleus. The corresponding factor for the Hf atom is much smaller. This leads to a re-evaluation of screening ratios for Hf and to a more accurate value of the nuclear parameter λ178,180 (Hf)=0.072(4) fm2.

  4. The CLEO II detector magnet

    International Nuclear Information System (INIS)

    For the last five years, the CLEO collaboration, which operates a large general-purpose particle detector at Cornell University's CESR e+e- storage ring, has been designing, procuring, and commissioning parts for a wholly new detector to replace the CLEO I, active from 1979 through 1987. The new detector, dubbed CLEO II, stresses very good energy resolution for photons and π0's as well as for charged particles. For good charged particle momentum resolution, a high magnetic field strength is desirable; for reasons of cost and saturation in the steel yoke, the design field was set at 1.5 T. The spatial and energy resolution for neutrals is to be attained with a highly segmented (approx. 8000 crystals) 30 ton array of CsI(Tl). So that the capabilities of the calorimeter not be compromised by extraneous material, the entire assembly should be contained within the coil ID; a superconducting solenoid with 3m ID, and 1.5 T field meets these needs. The design of the new magnet is described

  5. Revisited abundance diagnostics in quasars: Fe II/Mg II ratios

    Both the Fe II UV emission in the 2000- 3000 A region [Fe II (UV)] and resonance emission line complex of Mg II at 2800 A are prominent features in quasar spectra. The observed Fe II UV/ Mg II emission ratios have been proposed as means to measure the buildup of the Fe abundance relative to that of the alpha-elements C, N, O, Ne and Mg as a function of redshift. The current observed ratios show large scatter and no obvious dependence on redshift. Thus, it remains unresolved whether a dependence on redshift exists and whether the observed Fe II UV/ Mg II ratios represent a real nucleosynthesis diagnostic. We have used our new 830-level model atom for Fe+ in photoionization calculations, reproducing the physical conditions in the broad line regions of quasars. This modeling reveals that interpretations of high values of Fe II UV/ Mg II are sensitive not only to Fe and Mg abundance, but also to other factors such as microturbulence, density, and properties of the radiation field. We find that the Fe II UV/ Mg II...

  13. IGF-II receptors and IGF-II-stimulated glucose transport in human fat cells

    International Nuclear Information System (INIS)

    Insulin-like growth factor II (IGF-II) receptors have been described in rat but not in human adipocytes. In both species, IGF-II has been reported to stimulate glucose transport by interacting with the insulin receptor. In this study, we have unequivocally demonstrated the presence of IGF-II receptors in human adipocytes. 125I-labeled IGF-II specifically binds to intact adipocytes, membranes, and lectin-purified detergent solubilized extracts. Through the use of 0.5 mM disuccinimidyl suberate, 125I-IGF-II is cross-linked to a 260-kDa protein that is identified as the IGF-II receptor by displacement experiments with unlabeled IGF-II, IGF-I, and insulin and either by immunoprecipitation or by Western blot analysis with mannose 6-phosphate receptor antibodies. The concentrations of IGF-II required for half-maximal and maximal stimulation of glucose transport in human adipocytes are 35 and 100 times more than that of insulin. The possibility of IGF-II stimulating glucose transport by interacting predominantly with the insulin receptor is suggested by the following: (1) the concentration of IGF-II that inhibits half of insulin binding is only 20 times more than that of insulin; (2) the lack of an additive effect of IGF-II and insulin for maximal stimulation of glucose transport; (3) the ability of monoclonal insulin receptor antibodies to decrease glucose transport stimulated by submaximal concentrations of both IGF-II and insulin; and (4) the ability of IGF-II to stimulate insulin receptor autophosphorylation albeit at a reduced potency when compared with insulin

  14. [C II] and [N II] from dense ionized regions in the Galaxy

    Langer, W. D.; Goldsmith, P. F.; Pineda, J. L.

    2016-05-01

    Context. The interstellar medium (ISM) consists of highly ionized and neutral atomic, as well as molecular, components. Knowledge of their distribution is important for tracing the structure and lifecycle of the ISM. Aims: To determine the properties of the highly ionized gas and neutral weakly ionized gas in the Galaxy traced by the fine-structure lines of ionized nitrogen, [N ii], and ionized carbon, [C ii]. Methods: We utilize observations of the [C ii] 158 μm and [N ii] 205 μm fine-structure lines taken with the high spectral resolution Heterodyne Instrument in the Far-Infrared (HIFI) on the Herschel Space Observatory along ten lines of sight towards the inner Galaxy to analyze the ionized ISM. The [N ii] emission can be used to estimate the contribution of the highly ionized gas to the [C ii] emission and separate the contributions from highly ionized and weakly ionized neutral gas. Results: We find that [N ii] has strong emission in distinct spectral features along all lines of sight associated with strong [C ii] emission. The [N ii] arises from moderate density extended H ii regions or ionized boundary layers of clouds. Comparison of the [N ii] and [C ii] spectra in 31 separate kinematic features shows that many of the [C ii] spectra are affected by absorption from low excitation gas associated with molecular clouds, sometimes strongly so. The apparent fraction of the [C ii] associated with the [N ii] gas is unrealistically large in many cases, most likely due to the reduction of [C ii] by absorption. In a few cases the foreground absorption can be modeled to determine the true source intensity. In these sources we find that the foreground absorbing gas layer has C+ column densities of order 1018 cm-2. Conclusions: [C ii] emission arising from strong sources of [N ii] emission is frequently absorbed by low excitation foreground gas complicating the interpretation of the properties of the ionized and neutral gas components that give rise to [C ii] emission.

The incorporation of AgNPs in the structure of CS film and interaction between the polymer matrix and nanoparticles were confirmed by UV-vis and FTIR spectroscopy. The homogeneously embedded AgNPs (average diameter 29nm, TEM analysis) were clearly observed throughout the film by SEM. The CS-AgNPs nanocomposite film shows high sorption activity toward trace metals under optimized chemical conditions. The results suggest that the CS-AgNPs nanocomposite film can be feasibly used as a novel sorbent material for solid-phase extraction of metal pollutants from surface waters. PMID:27178907

    Many retrospective clinical and experimental investigations address the influence of statins on fracture healing. Simvastatin was shown to increase the expression of Bone morphogenetic protein (BMP-2)2, which is one of the most potent growth factors targeting bone formation in vivo. We therefore hypothesized a beneficial effect on fracture healing under local application of statins. A closed fracture of the right tibia of 5-month-old Sprague-Dawley rats (n=200) was applied.

    2015-01-01

    The proximity profile in the spectra of z~3 quasars, where fluxes extend blueward of the He II Lya wavelength 304 (1+z) A, is one of the most important spectral features in the study of the intergalactic medium. Based on the HST spectra of 24 He II quasars, we find that the majority of them display a proximity profile, corresponding to an ionization radius as large as 20 Mpc in the source's rest frame. In comparison with those in the H i spectra of the quasars at z~6, the He II proximity effect is more prominent and is observed over a considerably longer period of reionization. The He II proximity zone sizes decrease at higher redshifts, particularly at z > 3.3. This trend is similar to that for H I, signaling an onset of He II reionization at z~4. For quasar SDSS1253+6817 (z=3.48), the He II absorption trough displays a gradual decline and serves a good case for modeling the He II reionization. To model such a broad profile requires a quasar radiation field whose distribution between 4 and 1 Rydberg is consi...

  11. SEARCHING FOR NEW HYPERCOMPACT H II REGIONS

    International Nuclear Information System (INIS)

    Hypercompact (HC) H II regions are, by nature, very young H II regions, associated with the earliest stages of massive star formation. They may represent the transition phase as an early B-type star grows into an O-type star. Unfortunately, so few HC H II regions are presently known that their general attributes and defining characteristics are based on small number statistics. A larger sample is needed for detailed studies and good statistics. Class II methanol masers are one of the best indicators of the early stages of massive star formation. Using the Arecibo Methanol Maser Galactic Plane Survey-the most sensitive blind survey for 6.7 GHz methanol masers to date-we selected 24 HC H II region candidates. We made Expanded Very Large Array continuum observations at 3.6 and 1.3 cm to search for HC H II regions associated with these masers. We identified six potential HC H II regions in our sample based on the presence of optically thick free-free emission. Overall, we find that 30% of the methanol masers have an associated centimeter radio continuum source (separation less than 0.1 pc), which is in general agreement with previous studies.

Fairmont enthalpies of corresponding metal complexes were analyzed using titration calorimetry. This allowed to calculate full set of thermodynamic properties of processes. Binuclear heteroligand complexes [M2L(AcO)2)] (M = Cd, Hg) formation is most entropy favorable processes, that is evidently conditioned by the deliverance of large number of DMFA molecules from coordinating spheres of two solvate-cations when tetrapyrrole ligand coordination, and it demonstrates high thermodynamic stability of given ligands

  13. Status Report on PEP-II Performance

    International Nuclear Information System (INIS)

    PEP-II [1-9] is an e+e- collider with asymmetric energies (3.1 and 9 GeV, respectively) in a 2200 m tunnel at the Stanford Linear Accelerator Center. The collider produces B mesons to study a particle physics effect called CP violation as well as other physics topics. PEP-II was completed in 1998 with the first luminosity generated in July of that year. The installation of the BaBar Detector was finished in May 1999. The overall layout of PEP-II is shown in Figure 1 and the interaction region of PEP-II in Figure 2. The accelerator parameters and achievements of the High Energy Ring (HER) are listed in Table 1 and those for the Low Energy Ring (LER) in Table 2. The two beams collide at a single point in the IR2 hall where the BaBar detector is located. Beam parameters at the best luminosity are shown in Table 3 and PEP-II milestones in Table 4. In August 1999 PEP-II passed the world's record for luminosity which was 8.1x1032/cm2/s. The present luminosity in PEP-II is 2.15x1033 /cm2/s which is 72% of the design. In June 2000 PEP-II delivered an integrated luminosity of 150 pb-1 in one day, which is above the design integrated luminosity per day of 135 pb-1. Over the past year PEP-II has delivered over 12 fb-1 to BaBar. BaBar has logged over 11 pb-1. The present plan is collide until the end of October 2000 followed by a three month installation period

For each system, the composition of extracted species, their partition constants and the pH1/2 were determined. The most readily extractable were the Cu(II) complexes as well as tetrahedral species of Zn(II), Co(II) and Cd(II). In the case of 1-butyl-2-methylimidazole, the predominating effect on the extraction was exerted by hydrophobicity of the alkyl substituent in position '1' rather than the steric effect. With this extractant extraction of Ni(II) was enhanced, while that of Co(II) compounds was suppressed. The extractability of the complexes increased with increasing length of the 1-alkyl chain.

  15. Carlos II: el centenario olvidado

    Full Text Available RESUMEN: A partir de una reflexión inicial sobre el fenómeno de las conmemoraciones, el autor se plantea las causas por las que el tercer centenario de la muerte de Carlos II no dará lugar a ninguna conmemoración. Con independencia de las valoraciones de todo tipo que puedan hacerse de dichas celebraciones, lo cierto es que, en este caso, tal vez hubieran permitido acercar al gran público a uno de los monarcas peor conocidos y menos valorados de la historia de España. Lo más grave, sin embargo, es que la sombra del desconocimiento y el juicio peyorativo se extienden también sobre todo su reinado. Las investigaciones sobre aquel periodo, sin embargo, a pesar de que no abundan, muestran una realidad bastante distinta, en la que la decadencia y la pérdida de la hegemonía internacional convivieron con importantes iniciativas y realizaciones políticas, tanto en el ámbito interno de la Monarquía, como en las relaciones internacionales.ABSTRACT: Parting from an initial reflection about the phenomenon of commemorations, the author ponders the causes for which the third centenary of Charles IFs death will not be the subjet of any celebrations. Besides any evaluations which might be made of these events, the truth is that, perhaps, in this case, a commemoration would have brought the general public closer to one of the least known and worst valued monarchs in the history of Spain. What is more serious, however, is the fact that the shadow of ignorance and pejorative judgement extend also over the entirety of his reign. Though scarce, research about this period shows a very different reality, in wich decadence and the loss of international hegemony cohabitated with important political initiatives and achievements, both in the monarchy's internal domain and in the international arena.

  16. Probing Our Heliospheric History II

    A physical relationship between our local interstellar medium (ISM), galactic cosmic rays (GCR), and our planetary environment has long been a subject of interest to the astronomical community. Clouds of sufficient density to compress the heliosphere to within 1 AU are commonly seen throughout the galactic environment, including within the Local Bubble (LB). Such a compression would lead to an increase in the GCR flux at 1 AU and would have drastic consequences for many planetary processes such as atmospheric chemistry, lightning production, cloud cover, and DNA mutation rates for surface organisms. Prior to this work, we derived a column density profile of the ISM toward 49 bright stars along a narrow cone centered on the historical solar path. High resolution spectra were taken of NaI and CaII absorption out to a distance of 610 pc, with a median separation distance of 11 pc between adjacent stars. No absorption is seen out to a distance of 120 pc (consistent with the LB), but a complex number of absorbers is seen beyond. We now present the detection of several distinct clouds, their associated column densities, radial velocities, inferred distances, and size constraints. This combination of cloud properties allows us to derive a volume density profile of the ISM in the Sun's “rear-view mirror,” which represents one plausible record of actual ISM encounters for the Sun. We also make use of empirical relations to determine the effect these clouds would have on the historical heliosphere. Our analysis suggests that within the last 10 million years, if the Sun encountered a cloud with the same properties as we have detected along the solar historical trajectory, the Sun's termination shock would have resided inside the orbit of Uranus, with a GCR flux at Earth an order of magnitude greater than it is currently.

  17. Synthesis and characterisation of Cu(II), Ni(II), Mn(II), Zn(II) and VO(II) Schiff base complexes derived from o-phenylenediamine and acetoacetanilide

    Neutral tetradentate N2O2 type complexes of Cu(II), Ni(II), Mn(II), Zn(II) and VO(II) have been synthesised using a Schiff base formed by the condensation of -phenylenediamine with acetoacetanilide in alcohol medium. All the complexes were characterised on the basis of their microanalytical data, molar conductance, magnetic susceptibility, IR, UV-Vis 1H NMR and ESR spectra. IR and UV-Vis spectral data suggest that all the complexes are square-planar except the Mn(II) and VO(II) chelates, which are of octahedral and square pyramidal geometry respectively. The monomeric and neutral nature of the complexes was confirmed by their magnetic susceptibility data and low conductance values. The ESR spectra of copper and vanadyl complexes in DMSO solution at 300 K and 77 K were recorded and their salient features are reported.

    International Nuclear Information System (INIS)

    The dissociation constants of 2-(N-αbenzyl-2-hydroxbenzylidineimino) ethane sulphonic acid (H2BE) and stability constants of its chelates with CoII, NiII, CuII, ZnII, CdII, UVIO2 and VIVO have been determined in aqueous medium (μ-0.1 M) at 25, 35 and 45deg using Calvin's extension of Bjerrum's method. Values of ΔGo, ΔHo and ΔSo of the chelates have been evaluated. Elemental analysis, molecular weight, electronic and ir spectra, magnetic moments and conductance of the solid complexes indicate an octahedral stereochemistry for these chelates except those of the ZnII and CdII which possesses a tetrahedral geometry.

    Human heparin cofactor II is a plasma protein that is known to inhibit thrombin. The rate of thrombin inhibition by heparin cofactor II is accelerated (greater than or equal to 1000-fold) in the presence of the glycosaminoglycans, heparin and dermatan sulfate. We have found that chymotrypsin A alpha is also inhibited by heparin cofactor II with a second-order rate constant value of 1.8 X 10(6) M-1 X min-1 at pH 8.0 and 25 degrees C. However, there was no measurable effect of heparin or dermat...

    Hepcidin is a peptide hormone that regulates the homeostasis of iron metabolism. The N-terminal domain of hepcidin is conserved amongst a range of species and is capable of binding CuII and NiII through the amino terminal copper–nickel binding motif (ATCUN). It has been suggested that the binding of copper to hepcidin may have biological relevance. In this study we have investigated the binding of CuII with model peptides containing the ATCUN motif, fluorescently labelled hepcidin and hepcidi...

  2. Angiotensin II and Renal Tubular Ion Transport

    Evidence for the regulation of H+-ATPase activity in vivo and in vitro by trafficking/exocytosis has been provided. An additional level of H+-ATPase regulation via protein synthesis may be important as well. Recently, we have shown that both aldosterone and angiotensin II provide such a mechanism of regulation in vivo at the level of the medullary collecting tubule. Interestingly, in this part of the nephron, the effects of aldosterone and angiotensin II are not sodium dependent, whereas in the cortical collecting duct, both aldosterone and angiotensin II, by contrast, affect H+ secretion by sodium-dependent mechanisms.

The binding core of MHC-II-bound peptides is therefore not known a priori and the binding motif is hence not readily discernible. Recent progress has been obtained by including the......-specific methods have been able to make reasonably accurate predictions for alleles that were not included in the training data. These methods can be used to define supertypes (clusters) of MHC-II alleles where alleles within each supertype have similar binding specificities. Furthermore, the pan-specific methods...

    Experiments have been designed to reveal the influences of ferrofluid treatment and static magnetic field exposure on the photosynthetic system II, where the light harvesting complex (LHC II) controls the ratio chlorophyll a/ chlorophyll b (revealing, indirectly, the photosynthesis rate). Spectrophotometric measurement of chlorophyll content revealed different influences for relatively low ferrofluid concentrations (10-30 mul/l) in comparison to higher concentrations (70-100 mul/l). The overlapped effect of the static magnetic field shaped better the stimulatory ferrofluid action on LHC II system in young poppy plantlets.

    The conversion of the SECOM system to the SECOM II configuration has been completed and all communications between the central control station and vehicles carrying nuclear weapons and special nuclear materials are being handled by the SECOM II system. A summary of the system characteristics and the improvements achieved over the all-voice system is shown. Through the combined efforts of ALO and Sandia personnel, the transition from SECOM to SECOM II was achieved with a minimum disruption to the operation of the ERDA transportation system

  6. The separation of zinc(II) and cadmium(II) by liquid-liquid extraction

    International Nuclear Information System (INIS)

    The extraction of Zn(II) and Cd(II) from thiocyanate solutions with bis-2-ethylhexyl sulphoxide (B2EHSO) in benzene as an extractant has been studied by tracer techniques. For comparison, extraction has also been, carried out with tributylphosphate (TBP). The extraction data have been analysed by both graphical and theoretical methods by taking into account complexation of the metal in the aqueous phase by inorganic ligands and plausible complexes extracted into the organic phase. The results demonstrate that Zn(II) is extracted as Zn(SCN)2 * 2B2EHSO and Zn(SCN)2 * 2TBP. In the case of Cd(II), the extracted species are Cd(SCN)2 * 4B2EHSO/4TBP. The synergistic extraction of Zn(II) and Cd(II) with mixtures of 1-phenyl-3-methyl-4-benzoyl-pyrazolone-5 (HPMBP) and B2EHSO or TBP or trioctylphosphine oxide (TOPO) from acetate buffer solutions has also been investigated. (Zn(II) is extracted as Zn(PMBP)2 * B2EHSO/TBP/TOPO. On the other hand, Cd(II) is found to be not extracted with these mixed-ligand systems under the experimental conditions. These results also demonstrate the mutual separation of Zn(II) and Cd(II) using the synergistic extraction with HPMBP in the presence of various neutral oxodonors. (author)

  7. The type II collagen fragments Helix-II and CTX-II reveal different enzymatic pathways of human cartilage collagen degradation

    OBJECTIVE: Cartilage degradation in osteoarthritis (OA) generates the type II collagen fragments, Helix-II and CTX-II that can be used as clinical biological markers. Helix-II and C-telopeptide of type II collagen (CTX-II) levels are associated independently with progression of OA suggesting that...... they may be generated through different collagenolytic pathways. In this study we analyzed the release of Helix-II and CTX-II from human cartilage collagen by the proteinases reported to play a role in cartilage degradation. METHODS: In vitro, human articular cartilage extract was incubated with...... enzymatic pathways. Helix-II and CTX-II alone reflect only partially overall cartilage collagen degradation. These findings may explain why these two biological markers could provide complementary information on disease progression in OA....

    Full Text Available The sorption preconcentration of platinum (II, IV ions was investigated in presence of accompanying copper (II and zinc (II ions from chloride solutions on the new ion exchangers CYBBER (Russia, previously unexplored. The initial concentrations of platinum and accompanying ions were 0.25 mmol L-1 and 2.0 mmol L-1, respectively, and the acidity of medium was 0.001 - 4.0 mol L-1. It was shown that the resins investigated - strong and weak basic anion exchangers as well as chelate ion exchangers - possess good sorption and kinetic properties. The simultaneous sorption of investigated ions results in the complete recovery of platinum, while the non-ferrous metal ions are sorbed at less than 20%. Followed by the selective elution of platinum by thiourea (80 g L-1 solution in 0.3 M H2SO4, the quantitative isolation of platinum was achieved (more than 90%. Therefore, the studied ion exchangers can be recommended for recovery and separation of Pt(II,IV, Cu(II and Zn(II ions.

    Self-assembled bi- and polymetallic complexes of Co(II), Ni(II), Zn(II), and Cd(II) were obtained by the reaction of 4,4'-azopyridine (azpy) with metal tri-tert-butoxysilanethiolates (Co, 1; Cd, 2), acetylacetonates (Ni, 3; Zn, 4), and acetates (Cd, 5). All compounds were characterized by single-crystal X-ray structure analysis, elemental analysis, FTIR spectroscopy, and thermogravimetry. Complexes 1, 2 and 4, 5 exhibit diverse structural conformations: 1 is bimetallic, 2 and 4 are 1D coordination polymers, and 5 is a 2D coordination framework formed from bimetallic units. The obtained complexes contain metal atoms bridged by a molecule of azpy. The luminescent properties of 1-5 were investigated in the solid state. PMID:26178314

  11. Group II Intron Self-Splicing.

    Science.gov (United States)

    Pyle, Anna Marie

    2016-07-01

    Group II introns are large, autocatalytic ribozymes that catalyze RNA splicing and retrotransposition. Splicing by group II introns plays a major role in the metabolism of plants, fungi, and yeast and contributes to genetic variation in many bacteria. Group II introns have played a major role in genome evolution, as they are likely progenitors of spliceosomal introns, retroelements, and other machinery that controls genetic variation and stability. The structure and catalytic mechanism of group II introns have recently been elucidated through a combination of genetics, chemical biology, solution biochemistry, and crystallography. These studies reveal a dynamic machine that cycles progressively through multiple conformations as it stimulates the various stages of splicing. A central active site, containing a reactive metal ion cluster, catalyzes both steps of self-splicing. These studies provide insights into RNA structure, folding, and catalysis, as they raise new questions about the behavior of RNA machines. PMID:27391926

    International Nuclear Information System (INIS)

    This report describes the adaptation of the numerical transport shell ASTRA for performing plasma calculations in the TJ-II stellarator device. Firstly, an approximation to the TJ-II geometry is made and a simple transport model is shared with two other codes in order to compare these codes (PROCTR, PRETOR-Stellarator) with ASTRA as calculation tool for TJ-II plasmas are provided: interpretative and predictive transport. The first consists in estimating the transport coefficients from real experimental data, thes being taken from three TJ-II discharges. The predictive facet is illustrated using a model that is able to includes self-consistently the dynamics of transport barriers. The report includes this model, written in the ASTRA programming language, to illustrate the use of ASTRA. (Author) 26 refs

    Zodiac II is a proposed coronagraph on a balloon-borne platform, for the purpose of observing debris disks around nearby stars. Zodiac II will have a 1.2-m diameter telescope mounted in a balloon-borne gondola capable of arcsecond quality pointing, and with the capability to make long-duration (several week) flights. Zodiac II will have a coronagraph able to make images of debris disks, meaning that its scattered light speckles will be at or below an average contrast level of about 10(exp -7) in three narrow (7 percent) bands centered on the V band, and one broad (20%) one at I band. We will discuss the potential science to be done with Zodiac II.

    2014-09-01

    Hunter syndrome is caused by deficiency of the lysososmal enzyme iduronate-2-sulphatase that cleaves O-linked sulphate moieties from dermatan sulphate and heparan sulphate and leads to accumulation of GAGs. The disease is a X-linked condition affecting males and rarely females, clinically divided into severe (2/3) and attenuated types. Children with severe form, diagnosed at 12-36 months, have coarse facial feature, short stature, joint stiffness, short neck, broad chest, large head circumference, watery diarrhea, skeletal changes, progressive and profound mental retardation, retinal degeneration' hearing loss, cardiomyopathy, valvular involvement, with progressive thickening and stiffening of the valve leaflets leading to mitral and aortic regurgitation and stenosis . Recurrent and prolonged rhinitis with persistent nasal discharge are the first symptoms of airway disease that manifests itself as noisy breathing and later sleep apnea. Some patients develop ivory-colored skin lesions on the upper back and sides of the upper arms, pathogenomic of Hunter syndrome. The scalp hair becomes coarse, straight and bristly. Inguinal and umbilical hernias occur caused by the disturbed structure of connective tissue and increased liver and spleen volume. Patients with attenuated form have normal intelligence and a milder phenotype. Physical features diagnosed later are similar but less pronounced but progress to severe disease. Sceening is by quantitative assessment of urinary GAGs excretion. Qualitative assessment of GAG by electrophoresis can distinguish the type of mucopolysaccharidosis. Definitive diagnosis is based on enzyme activity assay in leukocytes, fibroblasts or plasma. Molecular testing is recommended mainly for genetic counseling and carrier detection. Limited experience of Haematopoietic stem cell therapy in MPS II showed progressive neurodegeneration. Recombinant 125 Idursulfase, is indicated for long-term treatment. The response appears to depend on the

    1998-01-01

    Excitonic molecules in GaAs/AlAs type-II superlattices are numerically investigated. In spite of large difference of electronic structures between type-II and type-I superlattices, variational calculations show that the configuration of particles is similar to that in type-I superlattices. This is because the layer width is smaller than the extent of excitonic wavefunctions in the direction parallel to the layers in the present superlattices.

    Experimental Breeder Reactor II (EBR-II) is an unmoderated, sodium-cooled reactor with a design power of 62.5 MWt. The primary cooling system is a submerged-pool type. The early operation of the reactor successfully demonstrated the feasibility of a sodium-cooled fast breeder reactor operating as an integrated reactor, power plant, and fuel-processing facility. In 1967, the role of EBR-II was reoriented from a demonstration plant to an irradiation facility. Many changes have been made and are continuing to be made to increase the usefulness of EBR-II for irradiation and safety tests. A review of EBR-II's operating history reveals a plant that has demonstrated high availability, stable and safe operating characteristics, and excellent performance of sodium components. Levels of radiation exposure to the operating and maintenance workers have been low; and fission-gas releases to the atmosphere have been minimal. Driver-fuel performance has been excellent. The repairability of radioactive sodium components has been successfully demonstrated a number of times. Recent highlights include installation and successful operation of (1) the hydrogen-meter leak detectors for the steam generators, (2) the cover-gas-cleanup system and (3) the cesium trap in the primary sodium. Irradiations now being conducted in EBR-II include the run-beyond-cladding breach fuel tests for mixed-oxide and carbide elements. Studies are in progress to determine EBR-II's capability for conducting important ''operational safety'' tests. These tests would extend the need and usefulness of EBR-II into the 1980's.

  4. Adsorption study of cadmium (II) and lead (II) on radish peels

    International Nuclear Information System (INIS)

    The removal efficiency of heavy metals like Cd(II) and Pb(II) from aqueous solutions by adsorption on Raphanus sativus (Radish peels) has been studied. The effects of time, pH, concentration of adsorbent and agitation speed on adsorption have been evaluated. It is found that radish peels powder has high removal efficiency for both the metals. Batch adsorption study has shown that Cd(II) and Pb(II) has been removed up to 88% and 86% respectively. Adsorption equilibriums for both metals have been described by the Langmuir isotherm. The maximum amount of heavy metals (Q ) adsorbed at max equilibrium were 7.5 and 1.23 mg/g for Cd(II) and Pb(II) respectively as evaluated by Langmuir isotherm. It is concluded that waste materials like radish peels can be used for removal of heavy metals from aqueous streams. (author)

This ligand was reacted with some metal ions (Co(II), Ni(II), Cu(II), Zn(II), and Cd(II) in methanol (1:1) metal: Ligand ratio in the presence of potassium hydroxide to give a series of new complexes of the general formula [M(H4L)], where: M=Co(II), Ni(II), Cu(II), Zn(II), and Cd(II). All compounds were determined ed by spectroscopic methods (IR, UV, VIS), CHNO analysis, and HPLC, atomic absorption, magnetic susceptibility, (El-mass for the ligand)], microanalysis along with conductivity measurements. From the obtained data the proposed molecular structure was suggested for ([Co(H4L)], [Ni(H4L) and [Cu(H4L)], complexes adopting square planar structure, and [Zn(H4L) and Cd (H4L)] complexes adopting a tetrahedral structure about the metal ions respectively.

  6. n-Linear Algebra of type II

    Kandasamy, W B Vasantha

    2009-01-01

    This book is a continuation of the book n-linear algebra of type I and its applications. Most of the properties that could not be derived or defined for n-linear algebra of type I is made possible in this new structure: n-linear algebra of type II which is introduced in this book. In case of n-linear algebra of type II we are in a position to define linear functionals which is one of the marked difference between the n-vector spaces of type I and II. However all the applications mentioned in n-linear algebras of type I can be appropriately extended to n-linear algebras of type II. Another use of n-linear algebra (n-vector spaces) of type II is that when this structure is used in coding theory we can have different types of codes built over different finite fields whereas this is not possible in the case of n-vector spaces of type I. Finally in the case of n-vector spaces of type II, we can obtain n-eigen values from distinct fields; hence, the n-characteristic polynomials formed in them are in distinct differ...

    Full Text Available A new sorbent was prepared using alumina and 5-Br-PADAP, and its adsorption ability for the removal of Ni(II and Pd(II from different waters was investigated. The procedure is based on retention of the analytes on the alumina load with 5-Br-PADAP at pH ~ 6. The separation/preconcentration conditions for the quantitative recoveries were investigated. The limit of detections (LOD based on three times the standard deviations of the blank, were 0.187 and 0.253 ng mL-1 for Ni(II and Pd(II, respectively. Obtained sorption capacities for 1 g sorbent were 6.0 mg Ni(II and 11.0 mg Pd(II. The linearity was maintained in the concentration range of 0.625 to 6.0 ng mL-1 for Ni(II and 0.416 to 7.0 ng mL-1 for Pd(II in the original solution. Eight replicate determinations of a mixture containing 2.0 µg mL-1 each of the elements in the final solution gave relative standard deviation of ±0.82 and ±1.12% for Ni(II and Pd(II, respectively. The proposed method was successfully applied to the determination trace amounts of Ni(II and Pd(II in the surface water samples.DOI: http://dx.doi.org/10.4314/bcse.v27i1.2

    Rhodium(II)-catalyzed reactions of aryldiazoacetates can be conducted in the presence of iodide, triflate, organoboron, and organostannane functionality, resulting in the formation of a variety of cyclopropanes or C-H insertion products with high stereoselectivity. The combination of the rhodium(II)-catalyzed reaction with a subsequent palladium(II)-catalyzed Suzuki coupling offers a novel strategy for diversity synthesis. PMID:16839138

    The competitive sorption of Pb(II), Cu(II) and Ni(II) on the uniform carbonaceous nanofibers (CNFs) was investigated in binary/ternary-metal systems. The pH-dependent sorption of Pb(II), Cu(II) and Ni(II) on CNFs was independent of ionic strength, indicating that inner-sphere surface complexation dominated sorption Pb(II), Cu(II) and Ni(II) on CNFs. The maximum sorption capacities of Pb(II), Cu(II) and Ni(II) on CNFs in single-metal systems at a pH 5.5±0.2 and 25±1°C were 3.84 (795.65mg/g), 3.21 (204.00mg/g) and 2.67 (156.70mg/g)mmol/g, respectively. In equimolar binary/ternary-metal systems, Pb(II) exhibited greater inhibition of the sorption of Cu(II) and Ni(II), demonstrating the stronger affinity of CNFs for Pb(II). The competitive sorption of heavy metals in ternary-metal systems was predicted quite well by surface complexation modeling derived from single-metal data. According to FTIR, XPS and EXAFS analyses, Pb(II), Cu(II) and Ni(II) were specifically adsorbed on CNFs via covalent bonding. These observations should provide an essential start in simultaneous removal of multiple heavy metals from aquatic environments by CNFs, and open the doorways for the application of CNFs.

    The interstellar medium (ISM) consists of highly ionized and neutral atomic, as well as molecular, components. Knowledge of their distribution is important for tracing the structure and lifecycle of the ISM. Here we determine the properties of the highly ionized and neutral weakly ionized gas in the Galaxy traced by the fine-structure lines of ionized nitrogen, [N II], and ionized carbon, [C II]. To analyze the ionized ISM we utilize [C II] 158 micron and [N II] 205 micron lines taken with the high spectral resolution Heterodyne Instrument in the Far-Infrared (HIFI) on the Herschel Space Observatory along ten lines of sight towards the inner Galaxy. [N II] emission can be used to estimate the contribution of the highly ionized gas to the [C II] emission and separate the highly ionized and weakly ionized neutral gas. We find that [N II] has strong emission in distinct spectral features along all lines of sight associated with strong [C II] emission. The [N II] arises from moderate density extended HII regions ...

    Bergeson, S. D.; Lawler, J. E.

    1993-01-01

    New absolute atomic transition probability measurements are reported for 12 transitions in Cr II and two transitions in Zn II. These transition probabilities are determined by combining branching ratios measured by classical techniques and radiative lifetimes measured by time-resolved laser-induced fluorescence. The measurements are compared with branching fractions, radiative lifetimes, and transition probabilities in the literature. The 206 nm resonance multiplets in Cr II and Zn II are included in this work. These multiplets are very useful in determining the distribution of the elements in the gas versus grain phases in the interstellar medium.

    Tiberg, Charlotta; Sjöstedt, Carin; Persson, Ingmar; Gustafsson, Jon Petter

    2013-11-01

    Transport of lead(II) and copper(II) ions in soil is affected by the soil phosphorus status. Part of the explanation may be that phosphate increases the adsorption of copper(II) and lead(II) to iron (hydr)oxides in soil, but the details of these interactions are poorly known. Knowledge about such mechanisms is important, for example, in risk assessments of contaminated sites and development of remediation methods. We used a combination of batch experiments, extended X-ray absorption fine structure (EXAFS) spectroscopy and surface complexation modeling with the three-plane CD-MUSIC model to study the effect of phosphate on sorption of copper(II) and lead(II) to ferrihydrite. The aim was to identify the surface complexes formed and to derive constants for the surface complexation reactions. In the batch experiments phosphate greatly enhanced the adsorption of copper(II) and lead(II) to ferrihydrite at pH effects were seen for lead(II).

    The homologous mammalian rho kinases (ROCK I and II) are assumed to be functionally redundant, based largely on kinase construct overexpression. As downstream effectors of Rho GTPases, their major substrates are myosin light chain and myosin phosphatase. Both kinases are implicated in microfilament...... persistent ROCK II and guanine triphosphate-bound RhoA. In contrast, the microfilament cytoskeleton was enhanced by ROCK II down-regulation. Phagocytic uptake of fibronectin-coated beads was strongly down-regulated in ROCK II-depleted cells but not those lacking ROCK I. These effects originated in part from...

  16. Removal of Pb(II), Cu(II) and Cd(II) from aqueous solution by some fungi and natural adsorbents in single and multiple metal systems

    International Nuclear Information System (INIS)

    Six fungal and 10 natural biosorbents were analyzed for their Cu(II), Cd(II) and Pb(II) uptake capacity from single, binary and ternary metal ion system. Preliminary screening biosorption of assays revealed 2 fungi (Aspergillus niger and Cunninghamella echinulata) and three natural [Cicer arietinum husk, Moringa oleifera flower and soil (clay)] adsorbents hold considerable high adsorption efficiency and capacity for 3 meta l ions amongst the adsorbents. Further biosorption trials with five elected adsorbents showed a considerable reduction in metal uptake capability of adsorbents in binary- and ternary systems as compared to singly metal system. Cd(II) manifested the highest inhibitory effect on the biosorption of other metal ions, followed by Pb(II) and Cu(II). On account of metal preference, the selectivity order for metal ion towards the studied biomass matrices was Pb(II) (40-90%) > Cd(II) (2-53%) > Cu(II) (2-30%). (author)

  18. The physics design of EBR-II

    International Nuclear Information System (INIS)

    The physics design oi EBR-II. Calculations of the static, dynamic and long-term reactivity behaviour of EBR-II are reported together with results and analysis of EBR-II dry critical and ZPR-III mock-up experiments. Particular emphasis is given to reactor-physics design problems which arise after the conceptual design is established and before the reactor is built or placed into operation. Reactor-safety analyses and hazards-evaluation considerations are described with their influence on the reactor design. The manner of utilizing the EBR-II mock-up on ZPR-III data and the EBR-II dry critical data is described. These experiments, their analysis and theoretical predictions are the basis for predetermining the physics behaviour of the reactor system. The limitations inherent in applying the experimental data to the performance of the power-reactor system are explored in some detail. This includes the specification of reactor core size and/or fuel-alloy enrichment, provisions for adequate operating and shut-down reactivity, determination of operative temperature and power coefficients of reactivity, and details of power- and flux-distribution as a function of position within the reactor structure. The overall problem of transferring information from simple idealized analytical or experimental geometry to actual hexagonal reactor geometry is described. Nuclear performance, including breeding, of the actual reactor system is compared with that of the idealized conceptual system. The long-term reactivity and power behaviour of the reactor blanket is described within the framework of the proposed cycling of the fuel and blanket alloy. Safety considerations, including normal and abnormal rates of reactivity-insertion, the implication of postulated reactivity effects based on the physical behaviour of the fuel alloy and reactor structure as well as extrapolation of TREAT experiments to the EBR-II system are analysed. The EBR-II core melt-down problem is reviewed. (author)

  19. Evaluation of follow up of vesicoureteral reflux into pylon - grade II (VUR II)

    International Nuclear Information System (INIS)

    Aim: Our previous work determined that the disappearance rate of VUR II. But the probability to detect VUR II or VUR III on first follow up study at time 0 in reflux unit (RU) with previously detected VUR II was only 47%. In this study we want to find out if the disappearance rate of VUR II is the same also for RU in which VUR II was not seen on first follow up study. Material and methods: In 61 RU (in 42 children younger than 12 years) with VUR II at the time of initial cyclic radionucline cystography (CRC) the second follow up CRC was repeated in average after 810 days. On first follow up CRC performed in average 421 days after the initial study reflux was not detected. Sequences of 5 sec. images from the beginning until the completion of the study was used for initial, first and second follow up report. Results: VUR II or VUR III was detected in 8 of 61 studied RU. The probability to detect VUR II or VUR III on second follow up, if reflux was not seen on the first follow up, was: 8/61 = 13%. If the first follow up was done 421 days after initial study the probability for negative result was 67%. The probability to detect VUR II or VUR III on second follow up if reflux was not detected on the first follow up study was: 13% * 0,67 9%. Probability calculated according to the proposed model to detect VUR II or VUR III on second follow up, if VUR was not detected on the first follow up was 25.Calculated probability to detect VUR II or VUR III on second follow up done at time 0, if reflux was not seen on first follow up was 25%. Conclusion: The probability to detect VUR II or VUR III on first follow up in RU with previously detected VUR II is 47%). The probability to detect VUR II or VUR III on second follow up in RU with previously detected VUR II if VUR was not seen on first follow up is 25%

    The work deals an application of ion flotation for selective removal of ion cesium(I), strontium(II), barium(II) and lead(II) from: (a) dilute and slightly acidic (pH=4 - 6) aqueous solutions of those ions at concentration -5 M; (b) radioactive sewages and waste solutions. The collective removal and separation of Cs(I), Sr(II), Ba(II), Pb(II) with macrocycle compounds, e.g. ionizable lariat ethers and non-ionizable foaming agent is shown
