    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 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.

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.

    2009-05-22

    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.

    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.

    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

    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.

Based on forty-five expert interviews, the perceptual, thought, and action patterns of administrative agents in police departments, regulatory authorities, and health authorities as well as of social work practitioners are reconstructed. The study offers valuable insights into the administrative practice and its constituting factors that otherwise frequently remain unnoticed in the analysis of prostitution politics.

  11. 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.)

    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.

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. The ARW is worried about new or newly identified organic substances in Rhine water, especially as there is a lack of toxicological data on these substances and of data concerning their behaviour during freshwater preparation for drinking.

    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. (orig.) [German] Ziel: MR-tomographische Untersuchung ischaemischer Posteriorinfarkte zur Erfassung der Haeufigkeit, des zeitlichen Verlaufs und der klinischen Bedeutung einer haemorrhagischen Transformation (HT). Methodik: Ueber einen Zeitraum von 42 Monaten wurden 48 Patienten mit 52 Territorialinfarkten im Versorgungsgebiet der Arteria cerebri posterior im MRT (T{sub 1}/T{sub 2}-gewichtete Spinecho-Sequenzen) untersucht. 77 MRT-Untersuchungen aus 5 verschiedenen Untersuchungszeitraeumen wurden hinsichtlich Lokalisation und Ausdehnung einer sekundaeren HT und etwaiger Veraenderungen im Verlauf analysiert.

    Legal actions taken by associations are part of environmental law in Europe and North America. In most cases, action is taken to set aside administrative acts. Action taken to set aside planned projects or abstract regulations of a general nature are an exception. On the European continent, the jurisdiction lies with administrative courts; in anglo-American countries, with civil courts. Denmark has a special institution for internal evaluation of decisions made by administrative bodies. A right of appeal is granted in most countries. Few countries make special demands on the structure of the association taking action. As far as the right of action is concerned, most countries require that the legal interests of a natural person most have been violated. In the case of legal actions taken by an association, the rights of the association are considered to be equal to the rights of a natural person. Limitations as in German law are uncommon, although federal states tend to make a distinction between decisions on federal and state level. (orig./HSCH) [Deutsch] Die Untersuchung zeigt, dass die Verbandsklage im Umweltschutzrecht in unterschiedlichen Formen in Europa und in Nordamerika zu finden ist. Meistens ist sie als Anfechtungsklage gegen Verwaltungsakte konzipiert, nur in Ausnahmefaellen koennen Plaene oder abstrakt-generelle Regelungen angefochten werden. In den kontinentaleuropaeischen Laendern sind die Verwaltungsgerichte, in den anglo-amerikanischen Laendern die Zivilgerichte fuer die Verbandsklagen zustaendig. In Daenemark ist ein spezielles Organ zur verwaltungsinternen Ueberpruefung von Entscheidungen zustaendig. Berufungsmoeglichkeiten sind in den meisten Laendern vorhanden. Nur in wenigen Laendern werden besondere formelle Erfordernisse an den Verband gestellt. Die Klagebefugnis ist dergestalt geregelt, dass meistens rechtliche Interessen einer natuerlichen Person fuer die Klageerhebung verletzt sein muessen. Fuer die Verbandsklage werden aber die Interessen

    The impact of the radiological contamination in Bavaria after the Chernobyl accident on childhood cancer was evaluated. According to caesium 137 in soil samples, Bavaria was subdivided in four regions with different contamination levels. The malignancies selected for analysis were: Leukaemia and non-Hodgkin lymphoma, tumors orginating in the embryonic period, tumors of the central nervous system and thyroid cancer. The temporal changes in the incidence of the selected tumors in the four regions were compared with the temporal changes in the rest of the Federal Republic of Germany (old laender). In addition, it was investigated, whether the tumor incidence after the Chernobyl accident showed a trend in connection with the degree of contamination. The results of the study neither show significant differences in the tumor incidence of regions with different contamination levels, nor are they indicative of a trend in the incidence in relation with contamination. Consequently, this study provides no evidence that the Chernobyl accident caused an increase in childhood cancer. Considering the latency periods of malignant diseases, however, a final evaluation is not yet possible. (orig.) [Deutsch] Der vorliegende Bericht untersucht die Frage einer nach dem Reaktorunfall in Tschernobyl erhoehten Inzidenz boesartiger Neubildungen bei Kindern in Bayern, demjenigen unter den alten Bundeslaendern, das durch den Unfall am staerksten kontaminiert wurde.

Im einzelnen handelt es sich um die Gruppe der Leukaemien und Non-Hodgkin-Lymphome, Tumoren mit Ursprung in der Embryonalzeit (maligne Keimzelltumoren, Nephroblastom, Neuroblastom, Retinoblastom), Tumoren des Zentrahnervensystems und Schilddruesenkarzinome. Die Analyse besteht einerseits in einem Vergleich zwischen unterschiedlich hohen exponierten Bevoelkerungsgruppen Bayerns mit der

    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

    Twenty patients treated by surgery for Perthes` disease were studied between 4 and 9 years postoperatively. In the clinical investigation eight patients complained of persistent stress-induced pain. In nine patients flexion, extension, ab- and adduction of the hip joint was limited. In the MRI-Study of ten hip joints a reduction of fatty marrow was seen in the femoral head. In 11 hip joints of patients complaining of persistent pain, a deformation of the femoral head (n = 2), a dysplasia of the femoral metaphysis (n = 2), and diaphysis (n = 4) or both (n = 2) were seen. In another five patients an additional dysplasia of the acetabulum was visualized. All these findings were diagnosed by X-ray studies as well. However, only by MRI were the extents of the postoperative defects of femoral spongiosa diagnosed in fifteen hip joints. (orig.) [Deutsch] 20 wegen eines Morbus Perthes operierte Patienten wurden 4-9 Jahre nach einer Umstellungsosteotomie klinisch, radiologisch und kernspintomographisch untersucht.

A recent inter-observer variation study showed profound variation in some variables. Further, some variables depend on a physician assessing...... them, making the score less applicable. The aim of the present study was to simplify the TBscore. Methods: Inter-observer variation assessment and exploratory factor analysis were combined to develop a simplified score, the TBscore II. To validate TBscore II we assessed the association between start...

    This work presents an experimental and theoretical investigation of a solar powered, discontinuously working dry absorption cooling machine. With the objective of simplicity and autarky in mind a simple prototype with small cooling power, sufficient e.g. for vaccine cooling was built and tested. The working principle relies on the chemical absorption of a refrigerant vapour (e.g. ammonia (NH{sub 3})) by a salt as absorbent. Two reactors containing the absorbent are mounted directly inside a concentrating solar collector. Thus the high temperature necessary for desorption of NH{sub 3} will be reached. The unit contains no moving parts neither inside the NH{sub 3} system nor inside a secondary cooling circuit. A proper operation of the desorption and absorption cycles is guaranteed by employing horizontal heat pipes. Furthermore a mathematical model for a solar powered dry absorption cooling machine is presented. The model is based on the transient two-dimensional heat conduction equation in cylindrical coordinates. The volumetric heat sources and heat sinks due to the chemical reaction as well as the anisotropic thermal conductivity of the absorbent is taken into account. In a long term investigation of the working pair NH{sub 3}/SrCl{sub 2} more than 2000 cycles of absorption and desorption were carried out. The 50% reaction time (i.e. the time it took for 50% of the NH{sub 3}-mass to react) changed during these 2000 cycles from 47 min to 60 min. The amount of NH{sub 3} available for the cooling cycle decreased by 6% of the original mass. The long term investigation demonstrated the viability of the working principle of dry absorption using the working pair NH{sub 3}/SrCl{sub 2}.

    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.

    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

    Salicylaldehyde semicarbazone (SALSC), yields complexes, ML/sub 2/.2H/sub 2/O (M = Co(II), Ni(II), Cu(II), Zn(II) and Cd(II)) and ML/sub 2/ (M = Be(II) and UO/sub 2/(VI)). The complexes have been characterized by analytical, spectral, magnetic and thermogravimetric studies. SALSC acts as a singly negatively charged bidentate anion, and two such anions coordinate to the metal ion through the hydroxyl oxygen and nitrogen of the C = N group yielding a neutral chelate. The complexes of Co(II), Ni(II) and Cu(II) are paramagnetic with magnetic moment values 4.93, 3.35 and 1.98 BM, respectively. The magnetic and spectral data suggest octahedral geometry of Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and UO/sub 2/(VI) complexes, whereas the Be(II) complex is tetrahedral. TG study reveals the order of thermal stability as : Zn(II) approximately equal to Ni(II) >Be(II) approximately equal to Cd(II) > UO/sub 2/(VI) approximately equal to Co(II) approximately equal to Cu(II).

    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.

    At present energy production is based on the combustion of fossil fuels and is the main cause of greenhouse gas emissions, which is to say it is the main cause of the climate change that is affecting the planet. On a worldwide scale, the use of solar concentration systems with systems capable of dissociating water is considered, from both an energy and an economic standpoint, as the most important long-term goal in the production of solar fuels to reduce the costs of hydrogen and to ensure practically zero carbon dioxide emissions. The Hydrosol II project has the largest pilot plant of its kind, and the Hydrosol II reactors will be capable of breaking up the water molecule on the basis of thermochemical cycles at moderate temperatures. The Hydrosol II project pilot plant is now a reality, located in the SSPS heliostats field of the Almeria Solar Platform. (Author)

    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.

    Full Text Available Iron(II, cobalt(II, nickel (II, copper (II, zinc(II and cadmium(II complexes of the type ML2Cl2, where M is a metal and L is the Schiff base N-(2-thienylmethylenemethanamine (TNAM formed by the condensation of 2-thiophenecarboxaldehyde and methylamine, were prepared and characterized by elemental analysis as well as magnetic and spectroscopic measurements. 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.

    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.

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.

    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.

    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° 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.

I will comment on the Jarlskog phases, $\\delta_{\\rm CKM}$ and $\\delta_{\\rm PMNS}$, in the CKM and PMNS matrices. In the type-II leptogenesis, the PMNS phase is used for Sakharov's condition on the global quantum number generation in the Universe. For this to be effective, the SU(2)$\\times$U(1) gauge symmetry must be broken during the leptogenesis epoch.

    figures developed very positively during the assessed time period. Until now, the focus of the content of contributions in NOVICE (Network of Veterinary ICT in Education has been on veterinary medicine teaching supported by e-Learning. An increase in the number of members would, however, be beneficial in order to further develop the network so that valuable exchange of information and informal learning can also take place in other specialist areas of veterinary medicine. [german] Zielsetzung: NOVICE (Network Of Veterinary ICt in Education, ist ein soziales professionelles online-Netzwerk für Tiermediziner, Dozierende und Studierende der Tiermedizin sowie für E-Learning-Berater bzw. Didaktiker der veterinärmedizinischen Bildungsstätten. In dieser Arbeit sollte untersucht werden, wie die Akzeptanz bei deutschen Tierärzten, Dozierenden und Studierenden der Veterinärmedizin sowie E-Learning-Beauftragten für ein fachspezifisches Netzwerk ist, welche Anforderungen durch die Nutzer an soziale online-Netzwerke gestellt werden, wie der Umgang mit Web 2.0-Werkzeugen , erfolgt und welches Potential ein berufsspezifisches Netzwerk bieten könnte. Methodik: Die Untersuchung erfolgte mittels Datenanalyse durch die Datenbank der Elgg-Plattform sowie zusätzlich mit google analytics. Jährliche Fokusgruppenbefragungen und Einzelinterviews wurden durchgeführt, um eine Akzeptanzanalyse der Netzwerk-Nutzer vorzunehmen.Ergebnisse: In NOVICE haben sich zwischen dem 01.

In den vorklinischen Fächern werden neben MC-Fragen auch Aufgaben mit offenen Fragen (OF zur Prüfung verwendet. Der statistische Vergleich beider Fragentypen in der praktischen Anwendung sollte ihre Eignung zur kursbegleitenden Prüfung, als Anreiz zur Steuerung des Lernverhaltens, prüfen. In einer retrospektiven Studie wurden die Prüfungsergebnisse von 351 Studierenden der Wintersemester 2003/04, 2004/05 und 2005/06 statistisch ausgewertet. Aus den gepaarten Daten der Prüfungsergebnisse von OF und MC-Fragen im gleichen Testatbogen wurden die Rang-Korrelationskoeffizienten nach Spearman und die F-Ratio berechnet. Zur Abschätzung der Reliabilität der beiden Fragenformate wurden die Raten korrekter Antworten auf einzelne, in zwei aufeinanderfolgenden Semestern eingesetzte, MC-Fragen und offene Fragen vergleichend untersucht. Als Maß für den Lernerfolg wurde die statistische Korrelation zwischen dem Ergebnis des Eingangstestats und späterer, im Verlaufe des Kurses abgelegter Testate ermittelt. Die statistische Untersuchung der gepaarten Daten ergab in allen untersuchten Semestern einen signifikanten Unterschied zwischen einem Anteil (Anzahl richtig beantworteter Fragen/Anzahl aller Testatfragen von 0.84 richtig beantworteter OF und von 0.71 richtig beantworteter MC- Fragen. Studierende mit insgesamt schlechterem Abschneiden wiesen eine signifikant höhere Fehlerrate bei der Beantwortung von MC-Fragen im Vergleich zu OF auf. Studierende mit einem unterdurchschnittlichen Ergebnis im Eingangstestat schnitten auch in späteren Testaten signifikant schlechter ab.

  12. 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.

    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.

    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.

    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.)

    Energy Technology Data Exchange (ETDEWEB)

    Thiessen, H.A.

    1982-08-01

    The present conception of LAMPF II is a high-intensity 16-GeV synchrotron injected by the LAMPF 800-MeV H/sup -/ beam. The proton beam will be used to make secondary beams of neutrinos, muons, pions, kaons, antiprotons, and hyperons more intense than those of any existing or proposed accelerator. For example, by taking maximum advantage of a thick target, modern beam optics, and the LAMPF II proton beam, it will be possible to make a negative muon beam with nearly 100% duty factor and nearly 100 times the flux of the existing Stopped Muon Channel (SMC). Because the unique features of the proposed machine are most applicable to beams of the same momentum as LAMPF (that is, < 2 GeV/c), it may be possible to use most of the experimental areas and some of the auxiliary equipment, including spectrometers, with the new accelerator. The complete facility will provide improved technology for many areas of physics already available at LAMPF and will allow expansion of medium-energy physics to include kaons, antiprotons, and hyperons. When LAMPF II comes on line in 1990 LAMPF will have been operational for 18 years and a major upgrade such as this proposal will be reasonable and prudent.

    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

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.

    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.

So verfügen die meisten Krankenhäuser bereits heute über ausgebaute Planungsmechanismen, beurteilen aber die dazu gehörige Informatikunterstützung als nicht prioritär.Dabei zeigen die bivariaten Auswertungen (Korrelationsmatrizen der Umfrage, dass gerade der IT als Träger oder Plattform des Performance-Managements eine zentrale Rolle zukommt.

    Full Text Available Major histocompatibility complex (MHC class II molecules are ligands for CD4+ T cells and are critical for initiating the adaptive immune response. This review is focused on what is currently known about MHC class II organization at the plasma membrane of antigen presenting cells and how this affects antigen presentation to T cells. The organization and diffusion of class II molecules have been measured by a variety of biochemical and microscopic techniques. Membrane lipids and other proteins have been implicated in MHC class II organization and function. However, when compared with the organization of MHC class I or TCR complexes, much less is known about MHC class II. Since clustering of T cell receptors occurs during activation, the organization of MHC molecules prior to recognition and during synapse formation may be critical for antigen presentation.

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

    Indian Academy of Sciences (India)

    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

    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 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

    Purpose: to evaluate the value of flat-panel CT (FP-CT) as a new perinterventional imaging modality in aortic stentgraft procedures. Materials and methods: FP-CT was performed in 21 patients (19 males, mean age 77, range 54 to 90) from June 2005 to February 2007 immediately after endovascular treatment of thoracic and abdominal aortic aneurysms on the angiographic table. Nine thoracic aortic aneurysms were treated with Zenith trademark -endoprosthesis. Nine of twelve abdominal aortic aneurysms were treated with Zenith trademark -Endoprosthesis and three with an Excluder trademark -Endoprosthesis. Images were acquired with a rotating C-arm and the following parameters: during an acquisition time of 20 seconds and at a rotation of 217 degrees, 538 projections were acquired. Contrast agent was administered in 14 patients. Images were displayed in MIP, MPR and VRT mode. Results: in all patients the stentgraft was shown exactly and the alignment of the prosthesis along the landing zones was well displayed. The aneurismal sack was well shown in all patients. 1 x an endoleak II was detected, 1 x an angiographically verified endoleak I was not detected. In one patient distal extension was considered due to suspected short stentgraft at the distal neck. Flat-panel CT showed sufficient neck coverage and no extension was inserted. Due to artifacts of the prosthesis, the platinum markers and the guide wire as well as due to pulsation of the aorta, the resolution of detail decreased and reduced the visualization of the alignment.

    Four novel mixed ligand complexes of Cu(II), Co(II), Ni(II) and Zn(II) with saccharin and nicotinamide were synthesised and characterised on the basis of elemental analysis, FT-IR spectroscopic study, UV-Vis spectrometric and magnetic susceptibility data. The structure of the Cu (II) complex is completely different from those of the Co(II), Ni(II) and Zn(II) complexes. From the frequencies of the saccharinato CO and SO 2 modes, it has been proven that the saccharinato ligands in the structure of the Cu complex are coordinated to the metal ion ([Cu(NA) 2(Sac) 2(H 2O)], where NA — nicotinamide, Sac — saccharinato ligand or ion), whilst in the Co(II), Ni(II) and Zn(II) complexes are uncoordinated and exist as ions ([M(NA) 2(H 2O) 4](Sac) 2).

    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.

    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.

  8. First 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 five runs of SAGE II give a capture rate of 76-18+21 (stat) -7+5 (sys) SNU. combined with the SAGE I result, the capture rate is 74-12+13 (stat) -7+5 (sys) SNU. This represents only 56%--60% of the capture rate predicted by different Standard Solar Models

  9. 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.)

    Ullrich, R. [Ktech Corp., Albuquerque, NM (United States)

    1998-07-01

    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.

  12. Type-II Weyl semimetals.

    Fermions--elementary particles such as electrons--are classified as Dirac, Majorana or Weyl. Majorana and Weyl fermions had not been observed experimentally until the recent discovery of condensed matter systems such as topological superconductors and semimetals, in which they arise as low-energy excitations. Here we propose the existence of a previously overlooked type of Weyl fermion that emerges at the boundary between electron and hole pockets in a new phase of matter. This particle was missed by Weyl because it breaks the stringent Lorentz symmetry in high-energy physics. Lorentz invariance, however, is not present in condensed matter physics, and by generalizing the Dirac equation, we find the new type of Weyl fermion. In particular, whereas Weyl semimetals--materials hosting Weyl fermions--were previously thought to have standard Weyl points with a point-like Fermi surface (which we refer to as type-I), we discover a type-II Weyl point, which is still a protected crossing, but appears at the contact of electron and hole pockets in type-II Weyl semimetals. We predict that WTe2 is an example of a topological semimetal hosting the new particle as a low-energy excitation around such a type-II Weyl point. The existence of type-II Weyl points in WTe2 means that many of its physical properties are very different to those of standard Weyl semimetals with point-like Fermi surfaces.

  18. 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

    Full Text Available A new macroacyclic amide ligand N,N’-bis(2-benzothiazolyl-2,6-pyridinedicarboxamide (BPD, formed by the condensation of 2,6-pyridinedicarbonyldichloride with 2-aminobenzothiazole, and its Cu(II, Ni(II, Co(II, Mn(II, Zn(II and Cd(II complexes were synthesized. Their structures were elucidated on the basis of elemental analyses, conductance measurements, magnetic moments, spectral (IR, NMR, UV-Visible, EPR and FAB and thermal studies. The complexes exhibit an octahedral geometry around the metal center. Conductance data of the complexes suggested them to be 1:1 electrolytes. The pentadentate behavior of the ligand was proposed on the basis of spectral studies. The X-band EPR spectra of the Cu(II and Mn(II complexes in the polycrystalline state at room (300 K and liquid nitrogen temperature (77 K were recorded and their salient features are reported.

    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.

    The manganese(II) carbonate, MnCO3.H2O, cobalt(II) carbonate, CoCO3.4H2O, zinc(II) carbonate, ZnCO3 and cadmium(II) carbonate, CdCO3, respectively, were synthesis by a new simple unusual route during the reaction of aqueous solutions of MnX2, CoX2, ZnX2 and CdX2, where (X = Br- and ClO$^{-}_{4}$) with urea at high temperature within ∼ 90°C for 6 h. The infrared spectra of the reaction products clearly indicate the absence of the bands of urea, but show the characteristic bands of ionic carbonate, CO$^{2-}_{3}$. A general mechanism describing the preparation of manganese(II), cobalt(II), zinc(II) and cadmium(II) carbonate compounds are discussed.

    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.

    Tyrosinemia type II or Richner-Hanhart syndrome is a rare hereditary disease characterized by the association of pseudoherpetiform corneal ulcerations and palmoplantar hyperkeratosis. We report the case of a 12 year-old young man presenting a superficial punctate keratitis and a corneal dystrophy in both eyes, associated with a palmoplantar hyperkeratosis. The dosage of the serum level of tyrosine is meaningfully raised to 1236 micromol/l. A dietary treatment restraining tyrosine and phenylalanine is started with favorable results after an evolution of 6 months. Tyrosinemia type II is an autosomal recessive disease, due to an enzymatic deficit in tyrosine aminotransferase. The diagnosis is based on the clinic and high level of serum and urinary tyrosine as well as of its urinary metabolites. This disease must be suspected in all cases of dentritic keratitis not reacting on the antiviral treatment, and more especially if it is associated with cutaneous lesions such as palmo-plantar keratosis.

    The Goldstone theorem implies the appearance of an ungapped mode whenever a continuous global symmetry is spontaneously broken. In general it does not say anything about the precise form of the dispersion relation nor does it imply that there is one massless mode for each broken symmetry generator. It is a well-established fact that even for relativistic field theories in the presence of a chemical potential Goldstone modes with quadratic dispersion relation, the type II Goldstone bosons, appear in the spectrum. We develop two holographic models that feature type II Goldstone modes as part of the quasinormal mode spectrum. The models are based on simple generalizations with U(2) symmetry of the well-studied holographic s-wave superfluid. Our results include Goldstone modes without broken generators but with unusual realization of symmetries and a frequency dependent conductivity of striking resemblance to the one of Graphene.

    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.

    2000-11-01

    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.

    Full Text Available Fraser D RussellSchool of Health and Sport Sciences, Faculty of Science, Health and Education, University of the Sunshine Coast, Sippy Downs, Queensland, AustraliaAbstract: Cardiovascular function is modulated by neuronal transmitters, circulating hormones, and factors that are released locally from tissues. 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. The purpose of this review is to consider the regulation of the cardiovascular system by UII, giving consideration to methodologies for measurement of plasma concentrations, sites of synthesis and triggers for release.Keywords: urotensin II, cardiovascular disease, heart failure, hypertension

    Full Text Available The purpose of this study was to determine the concentrations of heavy metals (Cd, Pb, Cu, Mn, and Zn in different organs (liver, kidney, muscle, lung, skin, and feathers of buzzards (Buteo buteo, utilized as a “biological indicator” for environmental contamination, from different areas of Sicily and to investigate the relationships between birds sex, age, and weight and metal levels in these samples. All samples of common buzzards were collected at the “Recovery Center of Wild Fauna” of Palermo, through the Zooprophilactic Institute. 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.

    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.)

  9. 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.

    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.

    2005-01-01

    Full Text Available Die Messverfahren zur Bestimmung der Schutzwirkung von HF-Schutzkleidung sind in der Norm DIN 32780-100 festgelegt. Entsprechend diesen Anforderungen wird die elektrische und magnetische Schirmdämpfung bestimmt und daraus als Maß für die Schutzwirkung die elektromagnetische Schirmdämpfung berechnet. Diese ist eine der SAR vergleichbare Größe. In diesem Beitrag werden die Einflüsse verschiedener Konstruktionsmerkmale von HF-Schutzanzügen auf die elektromagnetische Schirmdämpfung untersucht. Zu diesen gehören die nach MIL STD 285 vermessene elektrische Schirmdämpfung der verwendeten Gewebe. Weiter werden verschiedene Teilbereiche der HF-Schutzkleidung auf ihre Schutzwirkung untersucht. Der Schwerpunkt liegt hierbei auf der Fragestellung inwieweit Verschlüsse, Reißverschlüsse oder leitfähiges Klettband, die Schutzwirkung beeinträchtigen. Zu diesem Zweck werden zwei Schutzanzüge unterschiedlicher Konstruktion vergleichend vermessen. Es handelt sich dabei um einen bereits im Handel befindlichen und entsprechend der Norm zertifizierten Anzug und einen neuen Prototyp, welcher nach verschiedenen Gesichtspunkten optimiert wurde. Schwachstellen der Konstruktion werden herausgearbeitet und Ansatzpunkte für weitere Verbesserungen erarbeitet. The measuring methods for determining the shielding effectiveness of radiofrequency (RF-protective clothing are defined in German Standard DIN 32780-100. According to this standard, both the electric and the magnetic shielding effectiveness are measured in order to calculate the electromagnetic shielding effectiveness. The electromagnetic shielding effectiveness is an adequate quality criterion for the degree of protection and also compares well with the Specific Absorption Rate (SAR. In this article, the impact of different design features on the electromagnetic shielding effectiveness is analyzed. The electric shielding effectiveness of the used shielding materials is measured according to MIL STD 285 and thereupon taken into account. Moreover, different parts of the RF-Protective Clothing are analyzed in terms of shielding properties. The main focus is on the question to what extent seams and zippers impair the shielding properties. Therefore, two RF-protective suits with different design features are tested and compared. One of the tested suits is accredited according to German Standard and is already on the market. The other one is an optimized prototype. Weak spots concerning design features and starting points for further optimization are worked out.

    Cd(II)-, Pb(II)- and Zn(II)-cystine complexes were investigated by potentiometric and different mass spectrometric (MS) methodologies. Laser desorption mass spectrometry has provided both the composition and structure of metal-cystine complexes according to the speciation models proposed on the basis of the potentiometric data. Detection of neutral complexes was achieved by protonation or electrochemical reduction during mass spectrometric experiments. The redox activity of metal-cystine complexes was confirmed by laser desorption and charge transfer matrix assisted laser assisted MS experiments, which allowed us to observe the formation of complexes with a reduction of cystine. The stoichiometry of Cd(II)-, Pb(II)- and Zn(II)-cystine complexes was defined by observing the isotopic pattern of the investigated compound. The results suggest that interaction occurs through the carboxylate group of the ligand.

  1. 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.

    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...

    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.

  8. 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

    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...

  14. 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

    Tenuazonic acid (TA) is a phytotoxin produced by a fungal pathogen of rice, Pyricularia oryzae. The authors have synthesized and characterized the metal complexes of TA with copper (II), iron (III), nickel (II), and magnesium (II). The stoichiometry of the complexes determined by microanalysis and mass spectroscopy (D/CI) are Cu(II)TA2, Fe(III)TA3, Ni(II)TA2, and Mg(TA)2. Voltammograms of Fe(III)TA3, and Cu(II)TA2 in methanolic solutions confirmed this stoichiometry. Ni(II)TA2 paramagnetism and visible absorption data suggest an octahedral geometry. Fe(III)TA3 showed a characteristic visible absorption at 450 nm. Addition of Fe(III)Cl3 and Mg(II)Cl2 did not reverse the toxicity of NaTA to rice and bacterial cells, showing that this toxicity is not due to the privation of the cells of these metals essential for cell growth.

    We amplified and analyzed the complete cDNA of metalloprotein II (MP II) from the somatic muscle of the polychaete Perinereis aibuhitensis, the full length cDNA is 904 bp encoding 119 amino acids. The MP II cDNA sequence was subjected to BLAST searching in NCBI and was found to share high homology with hemerythrin of other worms. MP II expression of P. aibuhitensis exposed to single and combined metals (Cu(II), Cd(II)) was analyzed using real time-PCR. MP II mRNA expression increased at the start of Cu(II) exposure, then decreased and finally return to the normal level. Expression pattern of MP II under Cd(II) exposure was time- and dose-dependent. MP II expression induced by a combination of Cd(II) and Cu(II) was similar to that induced by Cd(II) alone.

    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.

    The cytotoxic oxoaporphine alkaloid liriodenine, isolated from Cananga odorata, was found to be a potent inhibitor of topoisomerase II (EC 5.99.1.3) both in vivo and in vitro. Liriodenine treatment of SV40 (simian virus 40)-infected CV-1 cells caused highly catenated SV40 daughter chromosomes, a signature of topoisomerase II inhibition. Strong catalytic inhibition of topoisomerase II by liriodenine was confirmed by in vitro assays with purified human topoisomerase II and kinetoplast DNA. Liriodenine also caused low-level protein-DNA cross-links to pulse-labeled SV40 chromosomes in vivo, suggesting that it may be a weak topoisomerase II poison. This was supported by the finding that liriodenine caused topoisomerase II-DNA cross-links in an in vitro assay for topoisomerase II poisons. Verapamil did not increase either liriodenine-induced protein-DNA cross-links or catalytic inhibition of topoisomerase II in SV40-infected cells. This indicates that liriodenine is not a substrate for the verapamil-sensitive drug efflux pump in CV-1 cells. PMID:9313773

    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.

  18. Aldosterone response to angiotensin II during hypoxemia

    Colice, G.L.; Ramirez, G.

    1986-07-01

    Exercise stimulates the renin-angiotensin-aldosterone system (RAAS). However, increases in plasma aldosterone concentrations (PAC) are suppressed when exercise is performed at high altitude or under hypoxemic conditions. As the angiotensin-II response to high-altitude exercise is normal, it is speculated that an inhibitor, discharged during hypoxemia, acted to suppress angiotensin-II-mediated aldosterone release. A study was conducted to test this hypothesis, taking into account the measurement of the aldosterone response to exogenous angiotensin II during normoxemia and hypoxemia. It was found that the dose-response curve of PAC to angiotensin II was not significantly inhibited by the considered model of hypoxemia. The hypoxemia-mediated release of an angiotensin II inhibitor does, therefore, not explain the previous observations of PAC suppression during hypoxemic exercise. 28 references.

  19. 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

  20. Radiosurgery for type II neurofibromatosis.

    Rowe, Jeremy; Radatz, Matthias; Kemeny, Andras

    2008-01-01

    A summary of our radiosurgical experience treating type II neurofibromatosis (NF2) vestibular schwannomas (VSs), based on a retrospective consecutive series of 122 tumours in 92 patients, with an extended series of a further 22 patients (906 patient-years of follow-up) to investigate the risk of malignancy after radiosurgery. With current techniques, we estimate that 8 years after radiosurgery for NF2 VS, 20% of patients will have required further treatment, 50% will be well controlled, and in 30% there will have been some concern about control, but they will have been managed conservatively. Three years after treatment, approximately 40% retain their functional hearing, 40% have some deterioration, 20% becoming deaf in that ear. The risk of facial palsy was 5%. Two malignancies were recorded after radiosurgery, in one the malignant behaviour preceded treatment. This is less than the previously reported rate of spontaneously developing malignant gliomas in NF2. Whilst the clinical results are far worse than those achieved treating sporadic tumours, this applies equally to the results of surgery or observation when treating NF2 tumours. It is important therefore that these patients are given advice specific for NF2. Considering this, we believe that radiosurgery remains a valuable minimally invasive treatment option for selected NF2 patients.

    Using the information from remake request slips in a dental school's predoctoral clinic, we examined the short-term survival of Class II resin composite restorations versus Class II dental amalgam restorations. In the student clinic, resin composite is used in approximately 58 percent of Class II restorations placed, and dental amalgam is used in the remaining 42 percent. In the period examined, Class II resin composite restorations were ten times more likely to be replaced at no cost to the patient than Class II dental amalgam restorations. A total of eighty-four resin composite restorations and six amalgam restorations were replaced due to an identified failure.

    Apolipoprotein (apo) C-II is a cofactor for lipoprotein lipase, the enzyme that catalyzes the hydrolysis of triglycerides on plasma triglyceride-rich lipoproteins. The complete coding sequence of apoC-II mRNA has been determined from an apoC-II clone isolated from a human liver cDNA library. A 17-base-long synthetic oligonucleotide based on amino acid residues 5-10 of apoC-II was utilized as a hybridization probe to select recombinant plasmids containing the apoC-II sequence. Two thousand fou...

    We study the nature of the [TiII] and [NiII] emission from the so-called strontium filament found in the ejecta of eta Carinae. To this purpose we employ multilevel models of the TiII and NiII systems which are used to investigate the physical condition of the filament and the excitation mechanisms of the observed lines. For the TiII ion, for which no atomic data was previously available, we carry out ab initio calculations of radiative transition rates and electron impact excitation rate coe...

    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.

    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...

    We studied the applicability of the Acute Physiology and Chronic Health Evaluation II (APACHE II) and Simplified Acute Physiology Score II (SAPS II) in patients admitted to the intensive care unit (ICU) with acute stroke and compared the results with the Glasgow Coma Scale (GCS) and National Institutes of Health Stroke Scale (NIHSS). We also conducted a comparative study of accuracy for predicting hemorrhagic and ischemic stroke mortality. Between January 2011 and December 2012, ischemic or hemorrhagic stroke patients admitted to the ICU were included in the study. APACHE II and SAPS II-predicted mortalities were compared using a calibration curve, the Hosmer-Lemeshow goodness-of-fit test, and the receiver operating characteristic (ROC) curve, and the results were compared with the GCS and NIHSS. Overall 498 patients were included in this study. The observed mortality was 26.3%, whereas APACHE II and SAPS II-predicted mortalities were 35.12% and 35.34%, respectively. The mean GCS and NIHSS scores were 9.43 and 21.63, respectively. The calibration curve was close to the line of perfect prediction. The ROC curve showed a slightly better prediction of mortality for APACHE II in hemorrhagic stroke patients and SAPS II in ischemic stroke patients. The GCS and NIHSS were inferior in predicting mortality in both patient groups. Although both the APACHE II and SAPS II systems can be used to measure performance in the neurosurgical ICU setting, the accuracy of APACHE II in hemorrhagic stroke patients and SAPS II in ischemic stroke patients was superior.

    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 present study describes the ecofriendly method for the preparation of chitosan film loaded with silver nanoparticles (CS-AgNPs) and application of this film as efficient sorbent for separation and enrichment of Al(III), Cd(II), Cu(II), Co(II), Fe(III), Ni(II), Pb(II) and Zn(II). The stable CS-AgNPs colloid was prepared by dispersing the AgNPs sol in chitosan solution at appropriate ratio and further used to obtain a cast film with very good stability under storage and good mechanical strength for easy handling in aqueous medium. 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

    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...

  16. Probing Our Heliospheric History II

    2012-05-01

    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. Angiotensin II receptors in testes

    1988-05-01

    Receptors for angiotensin II (AII) were identified and characterized in testes of rats and several primate species. Autoradiographic analysis of the binding of 125I-labeled (Sar1,Ile8)AII to rat, rhesus monkey, cebus monkey, and human testicular slide-mounted frozen sections indicated specific binding to Leydig cells in the interstitium. In rat collagenase-dispersed interstitial cells fractionated by Percoll gradient, AII receptor content was parallel to that of hCG receptors, confirming that the AII receptors are in the Leydig cells. In rat dispersed Leydig cells, binding was specific for AII and its analogs and of high affinity (Kd, 4.8 nM), with a receptor concentration of 15 fmol/10(6) cells. Studies of AII receptors in rat testes during development reveals the presence of high receptor density in newborn rats which decreases toward the adult age (4934 +/- 309, 1460 +/- 228, 772 +/- 169, and 82 +/- 12 fmol/mg protein at 5, 15, 20, and 30 days of age, respectively) with no change in affinity. At all ages receptors were located in the interstitium, and the decrease in binding was parallel to the decrease in the interstitial to tubular ratio observed with age. AII receptor properties in membrane-rich fractions from prepuberal testes were similar in the rat and rhesus monkey. Binding was time and temperature dependent, reaching a plateau at 60 min at 37 C, and was increased by divalent cations, EGTA, and dithiothreitol up to 0.5 mM. In membranes from prepuberal monkey testes, AII receptors were specific for AII analogs and of high affinity (Kd, 4.2 nM) with a receptor concentration of 7599 +/- 1342 fmol/mg protein. The presence of AII receptors in Leydig cells in rat and primate testes in conjunction with reports of the presence of other components of the renin-angiotensin system in the testes suggests that the peptide has a physiological role in testicular function.

    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.

  19. 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

    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.

    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.

    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.

  5. The influence of steric effect and chain length on extraction of the complexes of Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) with 1-alkyl-2-methylimidazoles

    International Nuclear Information System (INIS)

    Extraction of complexes of 1,2-dimethylimidazole, 1-ethyl-2-methylimidazole, 1-propyl-2-methylimidazole and 1-butyl-2-methylimidazole with Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) from aqueous solutions (I = 0.5 at 298 K) with benzyl alcohol was investigated. 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.

    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.

The results of antimicrobial studies indicate that Pt(II) and Pd(II) complexes showed the most activity against all bacteria. The crystal structure of 2-hydroxy-1-naphthaldehyde-N-methylpropanesulfonylhydrazone (nafpsmh) was also investigated by X-ray analysis. A series of Ni(II) sulfonyl hydrazone complexes (1-33) was synthesized and tested in vitro against Escherichia coli and Staphylococcus aureus. Their antimicrobial activities were used in the QSAR analysis. Four-parameter QSAR models revealed that nucleophilic reaction index for Ni and O atoms, and HOMO-LUMO energy gap play key roles in the antimicrobial activity.

  8. 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)

  9. Sorption recovery of platinum (II, IV in presence of copper (II and zinc (II from chloride solutions

    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.

    Production of elemental mercury, Hg(0), via Hg(II) reduction is an important pathway that should be considered when studying Hg fate in environment. We conducted a kinetic study of abiotic homogeneous and surface-catalyzed Hg(0) production by Fe(II) under dark anoxic conditions. Hg(0) production rate, from initial 50 pM Hg(II) concentration, increased with increasing pH (5.5–8.1) and aqueous Fe(II) concentration (0.1–1 mM). The homogeneous rate was best described by the expression, rhom = khom [FeOH+] [Hg(OH)2]; khom = 7.19 × 10+3 L (mol min)−1. Compared to the homogeneous case, goethite (α-FeOOH) and hematite (α-Fe2O3) increased and γ-alumina (γ-Al2O3) decreased the Hg(0) production rate. Heterogeneous Hg(0) production rates were well described by a model incorporating equilibrium Fe(II) adsorption, rate-limited Hg(II) reduction by dissolved and adsorbed Fe(II), and rate-limited Hg(II) adsorption. Equilibrium Fe(II) adsorption was described using a surface complexation model calibrated with previously published experimental data. The Hg(0) production rate was well described by the expression rhet = khet [>SOFe(II)] [Hg(OH)2], where >SOFe(II) is the total adsorbed Fe(II) concentration; khet values were 5.36 × 10+3, 4.69 × 10+3, and 1.08 × 10+2 L (mol min)−1 for hematite, goethite, and γ-alumina, respectively. Hg(0) production coupled to reduction by Fe(II) may be an important process to consider in ecosystem Hg studies.

  11. Mucopolysaccharidosis type II, Hunter's syndrome.

    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

    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.

  19. 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

  4. Transport with Astra in TJ-II

    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

    International Nuclear Information System (INIS)

    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

    The removal of heavy metals from wastewater using olive cake as an adsorbent was investigated. The effect of the contact time, pH, temperature, and concentration of adsorbate on adsorption performance of olive cake for Pb(II) and Cd(II) ions were examined by batch method. Adsorption of Pb(II) and Cd(II) in aqueous solution onto olive cake was studied in single component. After establishing the optimum conditions, elution of these ions from the adsorbent surface was also examined. The optimum sorption conditions were determined for two elements. Maximum desorption of the Pb(II) and Cd(II) ions were found to be 95.92 and 53.97% by 0.5 M HNO{sub 3} and 0.2 M HCl, respectively. The morphological analysis of the olive cake was performed by the scanning electron microscopy (SEM)

    The preferred crystallographic orientation developed during the ice I ← II transformation and during the plastic flow of ice II was measured in polycrystalline deuterium oxide (D2O) specimens using low-temperature neutron diffraction. Samples partially transformed from ice I to II under a non-hydrostatic stress developed a preferred crystallographic orientation in the ice II. Samples of pure ice II transformed from ice I under a hydrostatic stress and then when compressed axially, developed a strong preferred orientation of compression axes parallel to (1010). A match to the observed preferred orientation using the viscoplastic self-consistent theory was obtained only when (1010) [0001] was taken as the predominant slip system in ice II.

    Athabasca University Geophysical Observatory II (AUGO II) is a comprehensive subauroral zone observatory designed for routine automated optical and magnetic observation of the aurora. Becoming operational in February 2012, AUGO II has six temperature/humidity controlled observation rooms, each equipped with a 1.5 meter diameter acrylic dome custom fabricated for wide spectral transparency. AUGO II is located approximately 25 km southwest of the town of Athabasca, in Alberta, Canada, on the southern edge of the auroral zone (Geodetic coordinates: latitude 54 36' 10", longitude 113 38' 40" west. CGM coordinates: latitude 61.7, longitude 306.8, L-value 4.5). AUGO II is sufficiently isolated from urban development that skies are dark enough during winter months to allow optical studies of faint phenomena, such as H-beta studies of proton precipitation aurora, currently underway. The observatory's modest residence can accommodate six persons, allowing groups to live and work with their instruments for the duration of their research campaign without leaving the site. AUGO II's inaugural guest research campaign was reported successful, and resulted in a permanent VLF/LF radio experiment being deployed at the observatory's expansive site. We are hopeful more research groups will take advantage of this unique facility and help realize its full potential.

    We describe the case of a 68-year-old man with primary advanced adenocarcinoma of the stomach, who displayed extremely high plasma levels of protein induced by vitamin K antagonist (PIVKA)-II (15 600 mAU/ml) and normal levels of alphafetoprotein (AFP) (4 ng/ml). Ultrasonography and dynamic computed tomography ruled out hepatocellular carcinoma (HCC) or liver metastasis. After preoperative chemotherapy, pancreatico-spleno total gastrectomy with D2 lymphadenectomy was performed. Postoperatively, plasma levels of PIVKA-II returned to within the normal range (29 mAU/ml). Microscopic examination revealed stomach adenocarcinoma showing various histological types, such as moderately to poorly differentiated mucinous adenocarcinoma, but hepatoid differentiation of gastric adenocarcinoma was not detected. Localization of PIVKA-II and AFP within tumor cells was demonstrated by immunohistochemical staining using monoclonal antibodies. These results indicate that tumor cells from gastric cancer may produce PIVKA-II. Some cases of PIVKA-II- and AFP-producing advanced gastric cancer with liver metastasis have been reported, but this is the first report of gastric cancer without liver metastasis producing PIVKA-II alone.

Der Gesamtnatrium (Na-Gehalt könnte für die Untersuchung der Vitalität von Myokardgewebe verwendet werden, jedoch gibt es keine Berichte über die Entwicklung des Na-Gehalts in der chronischen Infarktnarbe im Vergleich zum normalen Myokard. Die vorliegende Studie untersucht die Änderungen des myokardialen Na-Gehalts während der Narbenentwicklung nach einem Myokardinfarkt (MI am Modell der Koronarligatur in der Ratte. Ratten wurden einer Ligatur des Ramus intraventricularis anterior unterzogen. Myokardgewebe von Kontrolltieren sowie infarziertes Gewebe wurden 1, 3, 7, 28 und 56 Tage postoperativ entnommen und der Na-Gehalt mittels 23Na-MRS und Ionenchromatographie bestimmt. Der Na-Gehalt nach MI war zu allen Zeitpunkten bei beiden Bestimmungsmethoden auf Werte zwischen 306 und 160 % des Kontrollwertes erhöht (n = 6-8 je Gruppe, p 0,01 vs. Kontrolle. Der Na-Gehalt ist im chronisch infarzierten Myokardgewebe zu allen Zeitpunkten erhöht. Damit kann überlebendes Myokard von einer Infarktnarbe anhand des Na-Gehalts unterschieden werden. Diese Information könnte in der 23Na-Magnetresonanzbildgebung (MRI zur Bestimmung der Infarktnarbe eine klinische Anwendung finden.

  4. Synthesis and characterisation of novel ligand type N2O2 and its complexes with Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) ions

    International Nuclear Information System (INIS)

    This work include ligand preparation from the reaction of ethylenediamine with [2,4,6-trihydroxyacetophenon] and KOH (Schiff Base) to give the new tetradentate ligand 2- (1-[2- [1-2, 6- Dihydroxy-4- methyl phenyl) - ethyliden amino]- ethylimino]- ethyl- benzene- 1, 3, 5- triol [H6L]. 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.

    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 luminosities, colors, and H{alpha} emission for 429 H II regions in 54 low surface brightness (LSB) galaxies are presented. While the number of H II regions per galaxy is lower in LSB galaxies compared to star-forming irregulars and spirals, there is no indication that the size or luminosity function of H II regions differs from other galaxy types. The lower number of H II regions per galaxy is consistent with their lower total star formation rates. The fraction of the total L{sub H{alpha}} contributed by H II regions varies from 10% to 90% in LSB galaxies (the rest of the H{alpha} emission being associated with a diffuse component) with no correlation with galaxy stellar or gas mass. Bright H II regions have bluer colors, similar to the trend in spirals; their number and luminosities are consistent with the hypothesis that they are produced by the same H II luminosity function as spirals. Comparison with stellar population models indicates that the brightest H II regions in LSB galaxies range in cluster mass from a few 10{sup 3} M{sub Sun} (e.g., {rho} Oph) to globular-cluster-sized systems (e.g., 30 Dor) and that their ages are consistent with clusters from 2 to 15 Myr old. The faintest H II regions are comparable to those in the LMC powered by a single O or B star. Thus, star formation in LSB galaxies covers the full range of stellar cluster mass.

  9. The Rho kinases I and II regulate different aspects of myosin II activity

    2005-01-01

    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...

  10. Phosphate effects on copper(II) and lead(II) sorption to ferrihydrite

    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 < 6. The largest effects were seen for lead(II).

    The Schiff base ligand, N,N'-bis-(2-thiophenecarboxaldimine)-3,3'-diaminobenzidine (L) obtained from condensation of 2-thiophenecarboxaldehyde and 3,3'-diaminobenzidine, was used to synthesize the complexes of type, [M 2L 2]Cl 4 [M = Co(II), Ni(II), Cu(II), Cd(II) and Hg(II)]. The newly synthesized ligand (L) was characterized on the basis of the results of elemental analysis, FT-IR, 1H NMR, 13C NMR, mass spectroscopic studies and single crystal X-ray crystallography. The characteristic resonance signals in 1H NMR and 13C NMR spectra indicated the presence of azomethine group as a result of condensation reaction. The stoichiometry, bonding and stereochemistries of complexes were ascertained on the basis of results of elemental analysis, magnetic susceptibility measurements, molar conductance and spectroscopic studies viz., FT-IR, 1H and 13C NMR, UV-vis and EPR. EPR, UV-vis and magnetic moment data revealed an octahedral geometry for complexes with distortion in Cu(II) complex and conductivity data show 1:2 electrolytic nature of complexes. Absoption and fluorescence spectroscopic studies supported that Schiff base ligand L and its Co(II), Ni(II) and Cu(II) complexes exhibited significant binding to calf thymus DNA. The complexes exhibited higher affinity to calf thymus DNA than the free Schiff base ligand L.

    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.

    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 ...

  15. Statistics of equivalent width data and new oscillator strengths for Si II, Fe II, and Mn II. [in interstellar medium

    Science.gov (United States)

    Van Buren, Dave

    1986-01-01

    Equivalent width data from Copernicus and IUE appear to have an exponential, rather than a Gaussian distribution of errors. This is probably because there is one dominant source of error: the assignment of the background continuum shape. The maximum likelihood method of parameter estimation is presented for the case of exponential statistics, in enough generality for application to many problems. The method is applied to global fitting of Si II, Fe II, and Mn II oscillator strengths and interstellar gas parameters along many lines of sight. The new values agree in general with previous determinations but are usually much more tightly constrained. Finally, it is shown that care must be taken in deriving acceptable regions of parameter space because the probability contours are not generally ellipses whose axes are parallel to the coordinate axes.

    Full Text Available Cimetidine is an important hydrogen histamine receptor and can coordinate metal ions in blood plasma. The stability of cimetidine and its complexes with Mn(II, Co(II and Ni(II was evaluated by studies of thermogravimetry (TG and differential thermal analysis (DTA. Cimetidine was thermally stable up to near 190 °C and above this temperature the thermal decomposition occurred in two stages. Complexes of [Mn(HCm2]Cl2, [Co(Cm2]Cl2 and [Ni(Cm2]Cl2 showed a similar behavior. The pyrolytic decomposition occurred in two stages at temperatures above 250 oC. A residue for each complex was detected at the end of the decomposition process. This probably corresponds to the respective metal oxide.

    Co(II), Ni(II) and Cu(II) complexes were synthesized with thiosemicarbazone (L 1) and semicarbazone (L 2) derived from 2-acetyl furan. These complexes were characterized by elemental analysis, molar conductance, magnetic moment, mass, IR, electronic and EPR spectral studies. The molar conductance measurement of the complexes in DMSO corresponds to non-electrolytic nature. All the complexes are of high-spin type. On the basis of different spectral studies six coordinated geometry may be assigned for all the complexes except Co(L) 2(SO 4) and Cu(L) 2(SO 4) [where L = L 1 and L 2] which are of five coordinated square pyramidal geometry.

    The purpose of this document is to provide the technical requirements for preparation for use, operation, inspection, and maintenance of a Transuranic Package Transporter Model II (TRUPACT-II) Shipping Package and directly related components. This document complies with the minimum requirements as specified in the TRUPACT-II Safety Analysis Report for Packaging (SARP) and Nuclear Regulatory Commission (NRC) Certificate of Compliance (C of C) 9218. In the event there is a conflict between this document and the TRUPACT-II SARP, the TRUPACT-II SARP shall govern. TRUPACT-II C of C number 9218 states, ''... each package must be prepared for shipment and operated in accordance with the procedures described in Chapter 7.0, Operating Procedures, of the application.'' It further states, ''... each package must be tested and maintained in accordance with the procedures described in Chapter 8.0, Acceptance Tests and Maintenance Program of the application.'' Chapter 9 of the TRUPACT-II SARP charges the Westinghouse Electric Corporation Waste Isolation Division (WID) with assuring that the TRUPACT-II is used in accordance with the requirements of the C of C. To meet this requirement and verify consistency of operations when loading and unloading the TRUPACT-II on the trailer, placing a payload in the packaging, unloading the payload from the packaging, or performing maintenance, the U.S. Department of Energy Carlsbad Area Office (U.S. DOE/CAO) finds it necessary to implement the changes that follow. This TRUPACT-II maintenance document represents a change to previous philosophy regarding site specific procedures for the use of the TRUPACT-II. This document details the instructions to be followed to consistently operate and maintain the TRUPACT-II. The intent of these instructions is to ensure that all users of the TRUPACT-II follow the same or equivalent instructions. Users may achieve this intent by any of the following methods: (1

    The Belle experiment, part of a broad-based search for new physics, is a collaboration of ~400 physicists from 55 institutions across four continents. The Belle detector is located at the KEKB accelerator in Tsukuba, Japan. The Belle detector was operated at the asymmetric electron-positron collider KEKB from 1999-2010. The detector accumulated more than 1 ab-1 of integrated luminosity, corresponding to more than 2 PB of data near 10 GeV center-of-mass energy. Recently, KEK has initiated a $400 million accelerator upgrade to be called SuperKEKB, designed to produce instantaneous and integrated luminosity two orders of magnitude greater than KEKB. The new international collaboration at SuperKEKB is called Belle II. The first data from Belle II/SuperKEKB is expected in 2015. In October 2012, senior members of the Belle-II collaboration gathered at PNNL to discuss the computing and neworking requirements of the Belle-II experiment with ESnet staff and other computing and networking experts. The day-and-a-half-long workshop characterized the instruments and facilities used in the experiment, the process of science for Belle-II, and the computing and networking equipment and configuration requirements to realize the full scientific potential of the collaboration's work.

    Proton Improvement Plan-II (PIP-II) is the centerpiece of Fermilab's plan for upgrading the accelerator complex to establish the leading facility in the world for particle physics research based on intense proton beams. PIP-II has been developed to provide 1.2 MW of proton beam power at the start of operations of the Long Baseline Neutrino Facility (LBNF), while simultaneously providing a platform for eventual extension of LBNE beam power to >2MW and enabling future initiatives in rare processes research based on high duty factor/higher beam power operations. PIP-II is based on the construction of a new 800 MeV superconducting linac, augmented by improvements to the existing Booster, Recycler, and Main Injector complex. PIP-II is currently in the development stage with an R&D program underway targeting the front end and superconducting RF acceleration technologies. This paper will describe the status of the PIPII conceptual development, the associated technology R&D programs, and the strategy for project implementation.

    2014-12-15

    Stenogyria, meaning multiple small compacted gyri separated by shallow sulci, is reported in the literature in association with Chiari II malformation (CM II) which in turn is reported in association with myelomeningocele (MMC). The authors present five cases of stenogyria (and other abnormalities found in CM II, like callosal hypoplasia/dysplasia, agenesis of the anterior commissure, hypoplasia of the falx cerebri) in children without the history of MMC or any other form of open spinal dysraphism. In these cases stenogyria was associated with Chiari I malformation, rhombencephalosynapsis and spina bifida. Stenogyria, which is not a true neuronal migration disorder, should not be mistaken for polymicrogyria which is also present in CM II. It is histologically different from polymicrogyria because the cortex is normally organized. Also on MRI, the general sulcal pattern is preserved in stenogyria, while it is completely distorted in polymicrogyria. The authors conclude that features traditionally attributed to CM II, like stenogyria, occur not only in the population of patients with MMC as opposed to the widely accepted theory.

    Phase II of the Centrifuge Workers Study was a follow-up to the Phase I efforts. The Phase I results had indicated a higher risk than expected among centrifuge workers for developing bladder cancer when compared with the risk in the general population for developing this same type of cancer. However, no specific agent could be identified as the causative agent for these bladder cancers. As the Phase II Report states, Phase I had been limited to workers who had the greatest potential for exposure to substances used in the centrifuge process. Phase II was designed to expand the survey to evaluate the health of all employees who had ever worked in Centrifuge Program Departments 1330-1339 but who had not been interviewed in Phase I. Employees in analytical laboratories and maintenance departments who provided support services for the Centrifuge Program were also included in Phase II. In December 1989, the Oak Ridge Associated Universities (ORAU), now known as Oak Ridge Institute for Science and Education (ORISE), was contracted to conduct a follow-up study (Phase II). Phase H of the Centrifuge Workers Study expanded the survey to include all former centrifuge workers who were not included in Phase I. ORISE was chosen because they had performed the Phase I tasks and summarized the corresponding survey data therefrom.

  4. Recent advances in angiotensin II signaling

    Directory of Open Access Journals (Sweden)

    R.M. Touyz

    2002-09-01

    Full Text Available Angiotensin II (Ang II* is a multifunctional hormone that influences the function of cardiovascular cells through a complex series of intracellular signaling events initiated by the interaction of Ang II with AT1 and AT2 receptors. AT1 receptor activation leads to cell growth, vascular contraction, inflammatory responses and salt and water retention, whereas AT2 receptors induce apoptosis, vasodilation and natriuresis. These effects are mediated via complex, interacting signaling pathways involving stimulation of PLC and Ca2+ mobilization; activation of PLD, PLA2, PKC, MAP kinases and NAD(PH oxidase, and stimulation of gene transcription. In addition, Ang II activates many intracellular tyrosine kinases that play a role in growth signaling and inflammation, such as Src, Pyk2, p130Cas, FAK and JAK/STAT. These events may be direct or indirect via transactivation of tyrosine kinase receptors, including PDGFR, EGFR and IGFR. Ang II induces a multitude of actions in various tissues, and the signaling events following occupancy and activation of Ang receptors are tightly controlled and extremely complex. Alterations of these highly regulated signaling pathways may be pivotal in structural and functional abnormalities that underlie pathological processes in cardiovascular diseases such as cardiac hypertrophy, hypertension and atherosclerosis.

In December 1989, the Oak Ridge Associated Universities (ORAU), now known as Oak Ridge Institute for Science and Education (ORISE), was contracted to conduct a follow-up study (Phase II). Phase H of the Centrifuge Workers Study expanded the survey to include all former centrifuge workers who were not included in Phase I. ORISE was chosen because they had performed the Phase I tasks and summarized the corresponding survey data therefrom

    Full Text Available Four Complexes of Cu (II and Ni (II Schiff bases have been prepared. The Schiff bases are derived by the reaction of Salisylaldoxime primary ligand with heterocyclic compounds such as 2-aminopyridine (S-L2, 2-2- bipyridine (S-L4 to form the secondary ligand, which than react with the metal halides to form corresponding complexes. The elemental analysis data shows that the metal to ligand ratio in all Ni(II and Cu(II simple complexes are 1:2 while for mixed ligand complexes having ratio 1:2:2 for S-L2 while it is 1:2:1 for S-L4. The structural features have been determined from IR, UV-Vis, and ESR data. All the complexes exhibit a distorted octahedral geometry to mononuclear Ni(II, Cu(II complexes of mixed ligands, while square planner geometry to mononuclear Ni(II, Cu(II complexes of oximes. All the synthesised ligands and their metal complexes were screened for antimicrobial activity

  8. Biosorption of cadmium (II) and lead (II) from aqueous solutions using mushrooms: A comparative study

    International Nuclear Information System (INIS)

    Sorption capacity of oyster mushroom (Pleurotus platypus), button mushroom (Agaricus bisporus) and milky mushroom (Calocybe indica) were evaluated on biosorption of heavy metals, viz. cadmium (II) and lead (II) from aqueous solutions. The optimum sorption conditions were studied for each metal separately. The desired pH of the aqueous solution was found to be 6.0 for the removal of cadmium (II) and 5.0 for removal of lead (II) for all the mushrooms. The percent removal of both the metals was found to increase with the increase in biosorbent dosage and contact time. The fitness of the biosorption data for Langmuir and Freundlich adsorption models was investigated. It was found that biosorption of cadmium (II) and lead (II) ions onto the biomass of the three mushrooms were better suitable to Langmuir than Freundlich adsorption model. P. platypus showed the highest metal uptake potential for cadmium (qmax 34.96 mg/g) whereas A. bisporus exhibited maximum potential for lead (qmax 33.78 mg/g). Milky mushroom showed the lowest metal uptake capacity for both the metals. The present data confirms that mushrooms may be used as efficient biosorbent for the removal of cadmium (II) and lead (II) ions from aqueous solution.

    Full Text Available The stability of metal–humate complexes is an important factor determining and predicting speciation, mobility and bioavailability of heavy metals in the environment. A comparative investigation of the complexation of Cu(II and Pb(II with humic acid and humic-like ligands, such as benzoic and salicylic acid, was performed. The analysis was realized at pH 4.0, a temperature of 25 °C and at an ionic strength of 0.01 mol dm-3 (NaCl using the Schubert ion-exchange method and its modified form. The stability constants were calculated from the experimental data by the Schubert method for complexes with benzoic and humic acid. A modified Schubert method was used for the determination of the stability constants of the complexes with salicylic acid. It was found that Cu(II and Pb(II form mononuclear complexes with benzoic and humic acid while with salicylic acid both metals form polynuclear complexes. The results indicate that Pb(II has a higher binding ability than Cu(II to all the investigated ligands. The Cu(II–salicylate and Pb(II–salicylate complexes showed noticeable higher stability constants compared with their complexes with humic acid, while the stabilities of the complexes with benzoic acid differed less. Salicylic and benzoic acids as humic-like ligands can be used for setting the range of stability constants of humic complexes with Cu(II and Pb(II.

    The adsorption characteristics of Cu(II) and Pb(II) onto expanded perlite (EP) from aqueous solution were investigated with respect to the changes in pH of solution, adsorbent dosage, contact time and temperature of solution. For the adsorption of both metal ions, the Langmuir isotherm model fitted to equilibrium data better than the Freundlich isotherm model. Using the Langmuir model equation, the monolayer adsorption capacity of EP was found to be 8.62 and 13.39 mg/g for Cu(II) and Pb(II) ions, respectively. Dubinin-Radushkevich (D-R) isotherm model was also applied to the equilibrium data and the mean free energies of adsorption were found as 10.82 kJ/mol for Cu(II) and 9.12 kJ/mol for Pb(II) indicating that the adsorption of both metal ions onto EP was taken place by chemical ion-exchange. Thermodynamic functions, the change of free energy (DeltaG degrees ), enthalpy (DeltaH degrees ) and entropy (DeltaS degrees ) of adsorption were also calculated for each metal ions. These parameters showed that the adsorption of Cu(II) and Pb(II) ions onto EP was feasible, spontaneous and exothermic at 20-50 degrees C. Experimental data were also evaluated in terms of kinetic characteristics of adsorption and it was found that adsorption process for both metal ions followed well pseudo-second-order kinetics.

    Full Text Available Abstract Background Distal alveolar morphogenesis is marked by differentiation of alveolar type (AT-II to AT-I cells that give rise to the primary site of gas exchange, the alveolar/vascular interface. Endothelial-Monocyte Activating Polypeptide (EMAP II, an endogenous protein with anti-angiogenic properties, profoundly disrupts distal lung neovascularization and alveolar formation during lung morphogenesis, and is robustly expressed in the dysplastic alveolar regions of infants with Bronchopulmonary dysplasia. Determination as to whether EMAP II has a direct or indirect affect on ATII→ATI trans-differentiation has not been explored. Method In a controlled nonvascular environment, an in vitro model of ATII→ATI cell trans-differentiation was utilized to demonstrate the contribution that one vascular mediator has on distal epithelial cell differentiation. Results Here, we show that EMAP II significantly blocked ATII→ATI cell transdifferentiation by increasing cellular apoptosis and inhibiting expression of ATI markers. Moreover, EMAP II-treated ATII cells displayed myofibroblast characteristics, including elevated cellular proliferation, increased actin cytoskeleton stress fibers and Rho-GTPase activity, and increased nuclear:cytoplasmic volume. However, EMAP II-treated cells did not express the myofibroblast markers desmin or αSMA. Conclusion Our findings demonstrate that EMAP II interferes with ATII → ATI transdifferentiation resulting in a proliferating non-myofibroblast cell. These data identify the transdifferentiating alveolar cell as a possible target for EMAP II's induction of alveolar dysplasia.

  16. Recovery of Cd(II), Co(II) and Ni(II) from Chloride Medium by Solvent Extraction Using CYANEX 923 and CYANEX 272 I

    International Nuclear Information System (INIS)

    The paper aims to study the extraction and separation of Cd(II), Co(II) and Ni(II) from their mixtures in hydrochloric acid medium with CYANEX 923 in kerosene. Preliminary investigations showed that only Cd(II) is extracted with CYANEX 923 while Co(II) and Ni(II) are not extracted. Different parameters affecting the extraction of Cd(II) with CYANEX 923 such as hydrochloric acid, hydrogen ion, extractant and metal concentrations, temperature investigations were also investigated. The stoichiometry of the extracted metal species investigated was found to be HCdCl3. 2 CYANEX 923. The stripping of the extracted Cd(II) species is obtained with 0.1 M HCl solution. Co(II) was found to be extracted with CYANEX 272 at ph 5.8 leaving Ni(II) in the solution. A developed process for the sequential of Cd(II), Co(II) and Ni(II) from their mixture in hydrochloric acid medium is proposed

  17. Foam separation of Cu (II) and Ni(II) from aqueous solutions and simulated wastewaters

    International Nuclear Information System (INIS)

    Batch experiments on the removal of Cu(II) and Ni(II) from aqueous solutions were performed through two foam separation techniques: precipitate flotation (PTF) an adsorbing colloid flotation (ACF). In ACF, Fe(III), oxyhydroxide was used as co precipitant and/or adsorbing colloid and sodium lauryl sulfate was used as a collector. ACF required a lower collector concentration than PTF. foreign ions were found to decrease the percent removal, the extent of decrease being higher by divalent ions than that by monovalent ones. However, the percent removal could be improved, even in presence of foreign ions, by addition of Al(II) as an activator. High removals could be attained for Cu(II) and Ni(II) from simulated wastewaters containing different concentrations of both metal ions. The addition of concentrations below the limits recommended by the egyptian regulations for environmental discharge

    The ternary piroxicam (Pir; 4-hydroxy-2-methyl- N-(2-pyridyl)-2H-1,2-benzothiazine-3-carboxamide 1,1-dioxide) complexes of Fe(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) with various amino acids (AA) such as glycine (Gly) or DL-phenylalanine (PhA) were prepared and characterized by elemental analyses, molar conductance, IR, UV-Vis, magnetic moment, diffuse reflectance and X-ray powder diffraction. The UV-Vis spectra of Pir and the effect of metal chelation on the different interligand transitions are discussed in detailed manner. IR and UV-Vis spectra confirm that Pir behaves as a neutral bidentate ligand coordinated to the metal ions via the pyridine- N and carbonyl group of the amide moiety. Gly molecule acted as a uninegatively monodentate ligand and coordinate to the metal ions through its carboxylic group, in addition PhA acted as a uninegatively bidentate ligand and coordinate to the metal ions through its carboxylic and amino groups. All the chelates have octahedral geometrical structures while Cu(II)- and Zn(II)-ternary chelates with PhA have square planar geometrical structures. The molar conductance data reveal that most of these chelates are non electrolytes, while Fe(III)-Pir-Gly, Co(II)-, Ni(II)-, Cu(II)- and Zn(II)-Pir-PhA cheletes were 1:1 electrolytes. X-ray powder diffraction is used as a new tool to estimate the crystallinity of chelates as well as to elucidate their geometrical structures.

    2006-04-01

    Lipid II is a membrane-anchored cell-wall precursor that is essential for bacterial cell-wall biosynthesis. The effectiveness of targeting Lipid II as an antibacterial strategy is highlighted by the fact that it is the target for at least four different classes of antibiotic, including the clinically important glycopeptide antibiotic vancomycin. However, the growing problem of bacterial resistance to many current drugs, including vancomycin, has led to increasing interest in the therapeutic potential of other classes of compound that target Lipid II. Here, we review progress in understanding of the antibacterial activities of these compounds, which include lantibiotics, mannopeptimycins and ramoplanin, and consider factors that will be important in exploiting their potential as new treatments for bacterial infections.

    The Miniaturized Moessbauer Spectrometer MIMOS II operates on the surface of Mars for the last three years (part of NASA Mars Exploration Rovers scientific payload). Successful application of MIMOS II as a tool for detection/analysis of Fe-bearing minerals on the extraterrestrial surfaces has proven its use for other missions. Currently MIMOS II is a part of ExoMars and Phobos-Grunt missions. ExoMars is managed by the European Space Agency and planned to be launched in 2013. It involves the development of a sophisticated Mars rover with set of instruments to further characterize the biological environment on Mars in preparation for robotic missions and human exploration. Data from the mission should provide an input for broader studies of exobiology. Phobos-Grunt is developed by Russian Space Agency. Currently, launch is planned in 2009. The main goals of the mission are Phobos regolith sample return, Phobos in situ study and Mars/Phobos remote sensing.

    Type II endoleaks are the most common endovascular complications of endovascular abdominal aortic aneurysm repair (EVAR); however, there has been a divided opinion regarding their significance in EVAR. Some advocate a conservative approach unless there is clear evidence of sac expansion, while others maintain early intervention is best to prevent adverse late outcomes such as rupture. There is a lack of level-one evidence in this challenging group of patients, and due to a low event rate of complications, large numbers of patients would be required in well-designed trials to fully understand the natural history of type II endoleak. This review will discuss the imaging, management, and outcome of patients with isolated type II endoleaks following infra-renal EVAR. PMID:27042087

  6. Intrafibrillar Mineral May be Absent in Dentinogenesis Imperfecta Type II (DI-II)

    2001-03-29

    High-resolution synchrotron radiation computed tomography (SRCT) and small angle x-ray scattering (SAXS) were performed on normal and dentinogenesis imperfecta type II (DI-II) teeth. Three normal and three DI-II human third molars were used in this study. The normal molars were unerupted and had intact enamel; donors were female and ranged in age from 18-21y. The DI-II specimens, which were also unerupted with intact enamel, came from a single female donor age 20y. SRCT showed that the mineral concentration was 33% lower on average in the DI-II dentin with respect to normal dentin. The SAXS spectra from normal dentin exhibited low-angle diffraction peaks at harmonics of 67.6 nm, consistent with nucleation and growth of the apatite phase within gaps in the collagen fibrils (intrafibrillar mineralization). In contrast, the low-angle peaks were almost nonexistent in the DI-II dentin. Crystallite thickness was independent of location in both DI-II and normal dentin, although the crystallites were significantly thicker in DI-II dentin (6.8 nm (s.d. = 0.5) vs 5.1 nm (s.d. = 0.6)). The shape factor of the crystallites, as determined by SAXS, showed a continuous progression in normal dentin from roughly one-dimensional (needle-like) near the pulp to two-dimensional (plate-like) near the dentin-enamel junction. The crystallites in DI-II dentin, on the other hand, remained needle-like throughout. The above observations are consistent with an absence of intrafibrillar mineral in DI-II dentin.

  12. The Gerda Phase II detector assembly

    International Nuclear Information System (INIS)

    Phase II of the Gerda (Germanium Detector Array) experiment will continue the search for the neutrinoless double beta decay (0νββ) of 76Ge. Prerequisites for Phase II are an increased target mass and a reduced background index of -3 cts/(keV.kg.yr). Major hardware upgrades to achieve these requirements are scheduled for 2013. They include the deployment of a new radio pure low mass detector assembly. The structural properties of available radio-pure materials and reduction of mass necessitate a change of the electrical contacting used to bias and read-out the detectors. The detector assembly design and the favored contacting solution are presented.

    Precise Ar(II) branching ratios have been measured on a high current hollow cathode with a 1-m Fourier transform spectrometer. Absolute transition probabilities for 11 Ar(II) lines were calculated from these branching ratios and lifetime measurements published by Mohamed et al. For the prominent 4806 Å line, the present result is Aik = 7.12×107s-1 ±2.8%, which is in excellent agreement with recent literature data derived from pure argon diagnostics, two-wavelength-interferometry, and Hβ-diagn...

  18. Scalar dark matter with type II seesaw

    International Nuclear Information System (INIS)

    We study the possibility of generating tiny neutrino mass through a combination of type I and type II seesaw mechanism within the framework of an abelian extension of standard model. The model also provides a naturally stable dark matter candidate in terms of the lightest neutral component of a scalar doublet. We compute the relic abundance of such a dark matter candidate and also point out how the strength of type II seesaw term can affect the relic abundance of dark matter. Such a model which connects neutrino mass and dark matter abundance has the potential of being verified or ruled out in the ongoing neutrino, dark matter, as well as accelerator experiments

  8. Colorimetric determination of copper(II), cobalt (II) and nickel(II) as complexes of ammonium pyrrolidinedithiocarbamate in cationic micellar medium

    International Nuclear Information System (INIS)

    Copper (II), nickel (II) and cobalt (II) were determined colorimetrically with ammonium pyrrolidinedithiocarbamate (APDC) as complexing reagent in aqueous phase in the presence of a cationic surfactant hexadecyltrimethylammonium bromide (CTAB). Beer's law is obeyed, for Cu(II), Ni(II) and Co(II) over the concentration range of 1.0- 4.0, 0.12 - 4.0 and 0.12-3.0 micro g ml/sup -1/ with the detection limits of 6.3, 2.9 and 2.9 ng ml/sup -1/ respectively. The lambda/sub max/, molar absorption, molar absorptivity and Sandal's sensitivity of Cu(II), Ni(II) and Co(II) were 442 nm, 325 nm and 331 nm; Epson/sub max/ = (x 10/sup 4/ mol/sup -1/ cm/sup -1/) is 1.0, 2.0 and 2.0: and (6.3), (2.9) and (2.9) ng cm/sup -2/ respectively. Validation of this method has been made by comparing the results with those obtained by flame atomic absorption spectrometry (AAS). No significant difference is noted between the results obtained by the two methods at 95% confidence level. The method is simple, accurate and economical and has been applied to the determination of copper(II), nickel(II) and cobalt(II) in wastewater and pharmaceutical samples. (author)

    Full Text Available The biosorption of Pb(II, Zn(II and Ni(II from industrial wastewater using Stenotrophomonas maltophilia and Bacillus subtilis was investigated under various experimental conditions regarding pH, metal concentration and contact time. The optimum pH values for the biosorption of the three metals were in the range 5.0-6.0, while the optimal contact time for the two bacterial species was 30 min. Experimental data was analyzed using Langmuir and Freundlich isotherms; the former had a better fit for the biosorption of Pb(II, Zn(II and Ni(II. The maximum adsorption uptakes (qmax of the three metals calculated from the Langmuir biosorption equation for S. maltophilia were 133.3, 47.8 and 54.3 for Pb(II, Zn(II and Ni(II, respectively, and for B. subtilis were 166.7, 49.7 and 57.8 mg/g, respectively. B. subtilis biomass was more favorable for the biosorption of Pb (II and Ni (II, while S. maltophilia was more useful for the biosorption of Zn (II.

    2007-07-01

    The aim of this study was to evaluate the scores of the Acute Physiology and Chronic Health Evaluation (APACHE) II and a modified APACHE II system (MAS), without parameters of biochemical tests; and to find prognostic value of individual elements of the APACHE II and MAS in predicting outcomes in organophosphate (OP) poisoning. Data were collected from 131 patients. The median (25th-75th percentiles) of APACHE II score for survivors without intubation were found to be lower than those of non survivors or survivors with intubation and ventilation, [4 (1-7); versus 17.5 (7.8-29), and 13.5 (7.8-16.3)]. Logistic regression analysis identified white blood cell (WBC), potassium, Glasgow coma scale (GCS), age and sodium in APACHE II; GCS and mean arterial pressure in MAS system as prognostically valuable. There was no statistically significance difference between APACHE II and MAS scores in terms of area under Receiver Operating Characteristic Curve [(0.902, 95% confidence interval: (0.837-0.947) for APACHE II), and (0.892, 95% confidence interval: (0.826-0.940) for MAS); P=0.74) to predict need for intubation. It is concluded usage of MAS facilitates the prognostication of the OP poisoned patients due to simplicity, less time-consuming and effectiveness in an emergency situation.

    Measurements of serum concentrations of Des-gamma-carboxy Prothrombin (PIVKA-II) are widely used for diagnosing hepatocellular carcinoma (HCC). Recently, in Lumipulsef assay, it was reported that antibodies against alkaline phosphatase (ALP) derived from anti bleeding sheets led false high values of PIVKA-II in the patients with HCC resection. To improve the previous issue, newly developed Lumipulse PrestoII assay was examined. (1) The assay was reliable and positively correlated with the previous assays (Lumipulse f and Picolumi, R = 0.997 and 0.994 (n=115), respectively). (2) Eleven cases, which had false high values of PIVKA-II by the Lumipulsef assay, were examined by the PrestoII assay with excess of inactive ALP. The false high values of 10 cases were improved, but only one was still high. False reactivity of this case was stronger than other cases, more effective adsorption was required. (3) Comparing the absorbent activity of inactive ALP among 6 different kinds, we found inactive ALP with much higher adsorbent activity. When this inactive ALP was applied to assay, false high values of PIVKA-II were improved in all 11 cases. In conclusion, the PrestoII assay, which applies the inactive ALP with high activity, is reliable and useful for clinical screening.

  12. Ultraviolet Emission Lines of Si ii in Quasars: Investigating the "Si ii Disaster"

    The observed line intensity ratios of the Si ii λ1263 and λ1307 multiplets to that of Si ii λ1814 in the broad-line region (BLR) of quasars are both an order of magnitude larger than the theoretical values. This was first pointed out by Baldwin et al., who termed it the “Si ii disaster,” and it has remained unresolved. We investigate the problem in the light of newly published atomic data for Si ii. Specifically, we perform BLR calculations using several different atomic data sets within the CLOUDY modeling code under optically thick quasar cloud conditions. In addition, we test for selective pumping by the source photons or intrinsic galactic reddening as possible causes for the discrepancy, and we also consider blending with other species. However, we find that none of the options investigated resolve the Si ii disaster, with the potential exception of microturbulent velocity broadening and line blending. We find that a larger microturbulent velocity (˜ 500 {km} {{{s}}}-1) may solve the Si ii disaster through continuum pumping and other effects. The CLOUDY models indicate strong blending of the Si ii λ1307 multiplet with emission lines of O i, although the predicted degree of blending is incompatible with the observed λ1263/λ1307 intensity ratios. Clearly, more work is required on the quasar modeling of not just the Si ii lines but also nearby transitions (in particular those of O i) to fully investigate whether blending may be responsible for the Si ii disaster.

  13. Solvent Refined Coal-II (SRC-II) detailed environmental plan

    Energy Technology Data Exchange (ETDEWEB)

    1980-10-01

    This document describes environmental research which will: aid in the development of an environmentally acceptable SRC-II process; and provide data for environmental assessment of the process. The SRC-II process is described, criteria for selection of samples to undergo environmental analyses are given, and approximate timelines are presented for obtaining pertinent samples. At this time, the SRC-II process is at the pilot-plant stage of development and a demonstration facility is scheduled to begin operation in 1984. Since design criteria may change, the environmental research described in this document is organized in four phases which correlate with and will provide information early in process development. Phase I research (screening) evaluates samples from existing SRC-II facilities (pilot, process demonstration unit (PDU), bench) which may bracket potential demonstration/commercial practice in terms of physical and chemical criteria. The samples are being subjected to a battery of short-term biomedical and ecological assays. Chemical fractionation and analysis are being performed to determine compounds and compound classes of potential concern. Phase II (baseline) research will evaluate SRC-II materials which are considered most representative of potential demonstration/commercial practice. These materials will be subjected to longer-term, more-extensive biological and ecological analyses relative to effects and environmental fate. Phase III research will examine effects of process modification, control technologies and changing operational conditions on potential environmental properties of SRC-II materials. Phase IV research (onsite monitoring) will develop methods and initiate environmental monitoring for effects at the SRC-II demonstration facility and potential commercial sites. This document also describes industrial hygiene programs which must occur throughout SRC-II process development.

    In this study, the acute toxicity and long-term outcome of a hyperfractionated accelerated chemoradiation regimen with cisplatin/5-fluorouracil (5-FU) in patients with locally advanced squamous cell carcinomas of head and neck were evaluated. From 2000-2002, 38 patients with stage III (5.3 %) and stage IV (94.7 %) head and neck cancer were enrolled in a phase II study. Patients received hyperfractionated-accelerated radiotherapy with 72 Gy in 15 fractions of 2 Gy followed by 1.4 Gy twice daily with concurrent, continuous infusion 5-FU of 600 mg/m{sup 2} on days 1-5 and 6 cycles of weekly cisplatin (30 mg/m{sup 2}). Acute toxicities (CTCAEv2.0), locoregional control (LRC), metastases-free (MFS), and overall survival (OS) were analyzed and exploratively compared with the ARO 95-06 trial. Median follow-up was 11.4 years (95 % CI 8.6-14.2) and mean dose 71.6 Gy. Of the patients, 82 % had 6 (n = 15) or 5 (n = 16) cycles of cisplatin, 5 and 2 patients received 4 and 3 cycles, respectively. Grade 3 anemia, leukopenia, and thrombocytopenia were observed in 15.8, 15.8, and 2.6 %, respectively. Grade 3 mucositis in 50 %, grade 3 and 4 dysphagia in 55 and 13 %. The 2-, 5-, and 10-year LRC was 65, 53.6, and 48.2 %, the MFS was 77.5, 66.7, and 57.2 % and the OS 59.6, 29.2, and 15 %, respectively. Chemoradiation with 5-FU and cisplatin seems feasible and superior in terms of LRC and OS to the ARO 95-06C-HART arm at 2 years. However, this did not persist at the 5- and 10-year follow-ups.

    Pencil graphite electrodes modified with Co(II), Ni(II), Cu(II) and Fe(II) metallophthalocyaninetetrasulfonates (MePcTSs) were investigated for an electrochemical determination of bisphenol A (BPA). The electrochemical performances of the modified electrodes for different pH values in phosphate and the Britton-Robinson buffers were determined by cyclic voltammetry; the electrode performances were better in the Britton-Robinson buffer. NiPcTS and CoPcTS modifications of the electrodes had remarkable enhancements on their performances. The differential pulse voltammetry parameters for the electrodes were optimized, and we found that the electrochemical response versus the concentration of BPA is linear from 5.0 × 10(-7) to 1.0 × 10(-5) M for the NiPcTS and CoPcTS modified electrodes. The detection limits of these modified electrodes are 2.9 × 10(-7) and 4.3 × 10(-7) M, respectively, and the effects of interfering species are less than 5%. The results show that NiPcTS and CoPcTS modified pencil graphite electrodes could be used for electrochemical determinations of BPA for analytical purposes. PMID:27506715

    Visualizing 3-dimensional (3-D) datasets is an important part of modern neuroimaging research. Many tools address this problem; however, they often fail to address specific needs and flexibility, such as the ability to work with different data formats, to control how and what data are displayed, to interact with values, and to undo mistakes. iiV, an interactive software program for displaying 3-D brain images, is described. This tool was programmed to solve basic problems in 3-D data visualization. It is written in Java so it is extensible, is platform independent, and can display images within web pages. iiV displays 3-D images as 2-dimensional (2-D) slices with each slice being an independent object with independent features such as location, zoom, colors, labels, etc. Feature manipulation becomes easier by having a full set of editing capabilities including the following: undo or redo changes; drag, copy, delete and paste objects; and save objects with their features to a file for future editing. It can read multiple standard positron emission tomography (PET) and magnetic resonance imaging (MRI) file formats like ECAT, ECAT7, ANALYZE, NIfTI-1 and DICOM. We present sample applications to illustrate some of the features and capabilities. iiV is an image display tool with many useful features. It is highly extensible, platform independent, and web-compatible. This report summarizes its features and applications, while illustrating iiV's usefulness to the biomedical imaging community

    Optimum concentrations of heavy metals like copper, cadmium, lead, chromium, and zinc in soil are essential in carrying out various cellular activities in minimum concentrations and hence help in sustaining all life forms, although higher concentration of these metals is lethal to most of the life forms. Galerina vittiformis, a macrofungus, was found to accumulate these heavy metals into its fleshy fruiting body in the order Pb(II) > Cd(II) > Cu(II) > Zn(II) > Cr(VI) from 50 mg/kg soil. It possesses various ranges of potential cellular mechanisms that may be involved in detoxification of heavy metals and thus increases its tolerance to heavy metal stress, mainly by producing organic acids and phytochelatins (PCs). These components help in repairing stress damaged proteins and compartmentalisation of metals to vacuoles. The stress tolerance mechanism can be deduced by various analytical tools like SEM-EDX, FTIR, and LC-MS. Production of two kinds of phytochelatins was observed in the organism in response to metal stress. PMID:24455671

    The aggregation of α-synuclein is associated with dopamine neuron death in Parkinson's disease. There is controversy in the field over the question of which species of the aggregates, fibrils or protofibrils, are toxic. Moreover, compelling evidence suggested the exposure to heavy metals to be a risk of PD. Nevertheless, the mechanism of metal ions in promoting PD remains unclear. In this research, we investigated the structural basis of Cu(II) induced aggregation of α-synuclein. Using transmission electron microscopy experiments, Cu(II) was found to promote in vitro aggregation of α-synuclein by facilitating annular protofibril formation rather than fibril formation. Furthermore, neuroprotective baicalein disaggregated annular protofibrils accompanied by considerable decrease of β-sheet content. These results strongly support the hypothesis that annular protofibrils are the toxic species, rather than fibrils, thereby inspiring us to search novel therapeutic strategies for the suppression of the toxic annular protofibril formation. - Highlights: • Cu(II) promoted the annular protofibril formation of α-synuclein in vitro. • Cu(II) postponed the in vitro fibrillization of α-synuclein. • Neuroprotective baicalein disaggregated annular protofibrils.

    An internal R&D program has been undertaken at BNL to develop a sub-micron RF Beam Position Monitor (BPM) for the NSLS-II 3rd generation light source that is currently under construction. The BPM R&D program started in August 2009. Successful beam tests were conducted 15 months from the start of the program. The NSLS-II RF BPM has been designed to meet all requirements for the NSLS-II Injection system and Storage Ring. Housing of the RF BPM's in +-0.1 C thermally controlled racks provide sub-micron stabilization without active correction. An active pilot-tone has been incorporated to aid long-term (8hr min) stabilization to 200nm RMS. The development of a sub-micron BPM for the NSLS-II has successfully demonstrated performance and stability. Pilot Tone calibration combiner and RF synthesizer has been implemented and algorithm development is underway. The program is currently on schedule to start production development of 60 Injection BPM's starting in the Fall of 2011. The production of {approx}250 Storage Ring BPM's will overlap the Injection schedule.

    Full Text Available Abstract Background Visualizing 3-dimensional (3-D datasets is an important part of modern neuroimaging research. Many tools address this problem; however, they often fail to address specific needs and flexibility, such as the ability to work with different data formats, to control how and what data are displayed, to interact with values, and to undo mistakes. Results iiV, an interactive software program for displaying 3-D brain images, is described. This tool was programmed to solve basic problems in 3-D data visualization. It is written in Java so it is extensible, is platform independent, and can display images within web pages. iiV displays 3-D images as 2-dimensional (2-D slices with each slice being an independent object with independent features such as location, zoom, colors, labels, etc. Feature manipulation becomes easier by having a full set of editing capabilities including the following: undo or redo changes; drag, copy, delete and paste objects; and save objects with their features to a file for future editing. It can read multiple standard positron emission tomography (PET and magnetic resonance imaging (MRI file formats like ECAT, ECAT7, ANALYZE, NIfTI-1 and DICOM. We present sample applications to illustrate some of the features and capabilities. Conclusion iiV is an image display tool with many useful features. It is highly extensible, platform independent, and web-compatible. This report summarizes its features and applications, while illustrating iiV's usefulness to the biomedical imaging community.

    2015-06-01

    Tears of the superior glenoid labrum are a common cause of shoulder pain and disability, especially in overhead athletes such as pitchers, swimmers, and volleyball players. Type II SLAP lesions have been the most clinically important superior labral pathology, and the management of this lesion has been a very controversial topic. Currently, there are no high level studies in the literature to guide treatment. While the few level 3 and level 4 evidence studies that are available following arthroscopic repair of type II SLAP lesions all report reasonable overall patient satisfaction, persistent postoperative pain is common and associated with a low return to pre-injury level of sports participation. There has been a recent school of thought that biceps tenodesis, which maintains the length-tension relationship of the long head of biceps, should be the procedure of choice for patients with isolated type II SLAP lesions. The current paper reviews the role biceps tenodesis plays in the management of type II SLAP tears.

    The microbunching instability has long been recognized as a potential limiting factor to the performance of X-ray FELs. It is of particular relevance in LCLS-II due, in part, to a layout that includes a long bypass beamline between the Linac and the undulators. Here we focus on two aspects of the instability that highlight the importance of 3D effects.

    2010-08-01

    Full Text Available OBJECTIVES: It is well known that the efficacy and the efficiency of a Class II malocclusion treatment are aspects closely related to the severity of the dental anteroposterior discrepancy. Even though, sample selection based on cephalometric variables without considering the severity of the occlusal anteroposterior discrepancy is still common in current papers. In some of them, when occlusal parameters are chosen, the severity is often neglected. The purpose of this study is to verify the importance given to the classification of Class II malocclusion, based on the criteria used for sample selection in a great number of papers published in the orthodontic journal with the highest impact factor. MATERIAL AND METHODS: A search was performed in PubMed database for full-text research papers referencing Class II malocclusion in the history of the American Journal of Orthodontics and Dentofacial Orthopedics (AJO-DO. RESULTS: A total of 359 papers were retrieved, among which only 72 (20.06% papers described the occlusal severity of the Class II malocclusion sample. In the other 287 (79.94% papers that did not specify the anteroposterior discrepancy severity, description was considered to be crucial in 159 (55.40% of them. CONCLUSIONS: Omission in describing the occlusal severity demands a cautious interpretation of 44.29% of the papers retrieved in this study.

  13. Cd(II and Pb(II complexes of the polyether ionophorous antibiotic salinomycin

    Directory of Open Access Journals (Sweden)

    Tanabe Makoto

    2011-09-01

    Full Text Available Abstract Background The natural polyether ionophorous antibiotics are used for the treatment of coccidiosis in poultry and ruminants. They are effective agents against infections caused by Gram-positive microorganisms. On the other hand, it was found that some of these compounds selectively bind lead(II ions in in vivo experiments, despite so far no Pb(II-containing compounds of defined composition have been isolated and characterized. To assess the potential of polyether ionophores as possible antidotes in the agriculture, a detailed study on their in vitro complexation with toxic metal ions is required. In the present paper we report for the first time the preparation and the structure elucidation of salinomycin complexes with ions of cadmium(II and lead(II. Results New metal(II complexes of the polyether ionophorous antibiotic salinomycin with Cd(II and Pb(II ions were prepared and structurally characterized by IR, FAB-MS and NMR techniques. The spectroscopic information and elemental analysis data reveal that sodium salinomycin (SalNa undergoes a reaction with heavy metal(II ions to form [Cd(Sal2(H2O2] (1 and [Pb(Sal(NO3] (2, respectively. Abstraction of sodium ions from the cavity of the antibiotic is occurring during the complexation reaction. Salinomycin coordinates with cadmium(II ions as a bidentate monoanionic ligand through the deprotonated carboxylic moiety and one of the hydroxyl groups to yield 1. Two salinomycin anions occupy the equatorial plane of the Cd(II center, while two water molecules take the axial positions of the inner coordination sphere of the metal(II cation. Complex 2 consists of monoanionic salinomycin acting in polydentate coordination mode in a molar ratio of 1: 1 to the metal ion with one nitrate ion for charge compensation. Conclusion The formation of the salinomycin heavy metal(II complexes indicates a possible antidote activity of the ligand in case of chronic/acute intoxications likely to occur in the stock

  14. Detection of Ca II absorption triplet in a circumnuclear H II region of NGC 3310

    International Nuclear Information System (INIS)

    We have obtained long slit spectrophotometry across NGC 3310, a luminous galaxy with circumnuclear bursts of star formation, covering the spectral range from λ3650 to 9700 A. In one giant star-forming region, the near-IR Ca II absorption lines (a signature of young supergiants) was detected with a strength similar to that of the nuclear region. This is, to our knowledge, the first detection of the IR Ca II triplet in an extragalactic giant H II region and confirms theoretical predictions that, after some 4 Myr, red supergiants should appear in bursts of star formation.

    Nair, M. Sivasankaran; Joseyphus, R. Selwin

    2008-09-01

    Co(II), Ni(II), Cu(II) and Zn(II) complexes of the Schiff base derived from vanillin and DL-α-aminobutyric acid were synthesized and characterized by elemental analysis, IR, electronic spectra, conductance measurements, magnetic measurements, powder XRD and biological activity. The analytical data show the composition of the metal complex to be [ML(H 2O)], where L is the Schiff base ligand. The conductance data indicate that all the complexes are non-electrolytes. IR results demonstrate the tridentate binding of the Schiff base ligand involving azomethine nitrogen, phenolic oxygen and carboxylato oxygen atoms. The IR data also indicate the coordination of a water molecule with the metal ion in the complex. The electronic spectral measurements show that Co(II) and Ni(II) complexes have tetrahedral geometry, while Cu(II) complex has square planar geometry. The powder XRD studies indicate that Co(II) and Cu(II) complexes are amorphous, whereas Ni(II) and Zn(II) complexes are crystalline in nature. Magnetic measurements show that Co(II), Ni(II) and Cu(II) complexes have paramagnetic behaviour. Antibacterial results indicated that the metal complexes are more active than the ligand.

  16. Zn(II) ions substantially perturb Cu(II) ion coordination in amyloid-β at physiological pH.

    Silva, K Ishara; Saxena, Sunil

    2013-08-15

    The interaction of Cu(II) and Zn(II) ions with amyloid-β (Aβ) plays an important role in the etiology of Alzheimer's disease. We describe the use of electron spin resonance (ESR) to measure metal-binding competition between Cu(II) and Zn(II) in amyloid-β at physiological pH. Continuous wave ESR measurements show that the affinity of Cu(II) toward Aβ(1-16) is significantly higher than that of Zn(II) at physiological pH. Importantly, of the two known Cu(II) coordination modes in Aβ, component I and component II, Zn(II) displaces Cu(II) only from component I. Our results indicate that at excess amounts of Zn(II) component II becomes the most dominant coordination mode. This observation is important as Aβ aggregates in the brain contain a high Zn(II) ion concentration. In order to determine details of the metal ion competition, electron spin echo envelope modulation experiments were carried out on Aβ variants that were systematically (15)N labeled. In the presence of Zn(II), most peptides use His 14 as an equatorial ligand to bind Cu(II) ions. Interestingly, Zn(II) ions completely substitute Cu(II) ions that are simultaneously coordinated to His 6 and His 13. Furthermore, in the presence of Zn(II), the proportion of Cu(II) ions that are simultaneously coordinated to His 13 and His 14 is increased. On the basis of our results we suggest that His 13 plays a critical role in modulating the morphology of Aβ aggregates.

  17. Angiotensin II during experimentally simulated central hypovolemia

    Directory of Open Access Journals (Sweden)

    Theo Walther Jensen

    2016-03-01

    Full Text Available Abstract:Central hypovolemia, defined as diminished blood volume in the heart and pulmonary vascular bed, is still an unresolved problem from a therapeutic point of view. The development of pharmaceutical agents targeted at specific angiotensin II receptors, like the non-peptidergic AT2-receptor agonist compound 21, is yielding many opportunities to uncover more knowledge about angiotensin II receptor profiles and possible therapeutic use. Cardiovascular, anti-inflammatory and neuroprotective therapeutic use of compound 21 have been suggested. However, there has not yet been a focus on the use of these agents in a hypovolemic setting. We argue that the latest debates on the effect of angiotensin II during hypovolemia might guide for future studies investigating the effect of such agents during experimentally simulated central hypovolemia. The purpose of this review is to examine the role of angiotensin II during episodes of central hypovolemia.To examine this, we reviewed results from studies with three experimental models of simulated hypovolemia: head up tilt table test, lower body negative pressure, and hemorrhage of animals. A systemic literature search was made with the use of PubMed/MEDLINE for studies that measured variables of the renin-angiotensin system or its effect during simulated hypovolemia. 12 articles, using one of the three models, were included and showed a possible organ protective effect and an effect on the sympathetic system of angiotensin II during hypovolemia. The results support the possible organ protective vasodilatory role for the AT2-receptor during hypovolemia on both the kidney and the splanchnic tissue.

    1. Acute toxicity tests with the Bt-spray product MVP®II (active substance Cry11Ac) exhibited in Folsomia candida a LC50 of 12,48 mg/g Lufa 2.1 soil and 1,08 mg/g quartzous sand. Presumably this was an effect of seed treatment products. 2. Trypsin-resistant Cry1Ab (Monsanto, SLFA Neustadt) caused no effects on F. candida in acute toxicity tests (maximum concentration: 80 respectively 125 µg/g soil). 3. Trypsin-resistant Cry1Ab (Monsanto) caused no effect on F. candida in reproduction tests (m...

    Full Text Available The preparation and properties of some complexes of cobalt(II, zinc(II and copper(II with several newly synthesized benzimidazole derivatives (L are reported. The complexes, of the general formula [MCl2L2] (M=Co(II, Zn(II and [CuCl2L(H2O], have a tetrahedral structure. The complexes were characterized by elemental analysis, molar conductivity, magnetic susceptibility measurements, IR and absorption electronic spectra. The antibacterial activitiy of the benzimidazoles and their complexes was evaluated against Erwinia carotovora subsp. carotovora and Erwinia amylovora. The complexes were found to be more toxic than the ligands.

    Azo-Schiff-base complexes of VO(II), Co(II), Ni(II), Cu(II) and Zn(II) have been synthesized and characterized by elemental analysis, IR, UV-Vis, 1H NMR, mass spectra, molar conductance, magnetic susceptibility measurement, electron spin resonance (EPR), CV, fluorescence, NLO and SEM. The conductance data indicate the nonelectrolytic nature of the complexes, except VO(II) complex which is electrolytic in nature. On the basis of electronic spectra and magnetic susceptibility octahedral geometry has been proposed for the complexes. The EPR spectra of copper and oxovanadium complexes in DMSO at 300 and 77 K were recorded and its salient features are reported. The redox behavior of the copper(II) complex was studied using cyclic voltammetry. The in vitro antimicrobial activity against Staphylococcus aureus, Escherichia coli, Salmonella enterica typhi, Bacillus subtilis and Candida strains was studied and compared with that of free ligand by well-diffusion technique. The azo Schiff base exhibited fluorescence properties originating from intraligand (π-π∗) transitions and metal-mediated enhancement is observed on complexation and so the synthesized complexes can serve as potential photoactive materials as indicated from their characteristic fluorescence properties. On the basis of the optimized structures, the second-order nonlinear optical properties (NLO) are calculated by using second-harmonic generation (SHG) and also the surface morphology of the complexes was studied by SEM.
