    In this work investigations on r-process nuclides around the N = 82 shell closure are done. The so far unknown half-lives and P{sub n}-values of {sup 137-139}Sb and {sup 139}Te and their impact to r-process theory are given. Further the results of Shergur et. al. of neutron rich tin ({sup 137,138}Sn) are verified and in some points improved. New data on {gamma}-decay spectroscopy for {sup 136}Sn from single spectra is published. To improve beam quality and solve long known problems on ISOL-facilities with isobaric contamination, new techniques are discussed. A special focus is on molecular sidebands, which is first time adapted to a target/ion source unit in a mass separation facility. It was possible to create a strong SnS{sup +} sideband and in this way to reduce isobaric background with good beam intensities. On the other hand, a target with temperature controlled transfer line was build and its characteristics are discussed. To improve selectivity of a given experiment on neutron rich nuclei a new detector system for n{gamma}-coincidences was developed. Due to a special electronically setup of the new system it was possible to downsize the coincidence window compared to earlier attempts. (orig.)

  2. Studies on the microbial sulphur cycle in acid ponds in the Niederlausitz mining region in Brandenburg; Untersuchungen zum mikrobiellen Schwefelkreislauf in sauren Tagebau-Restseen der Niederlausitz (Brandenburg)

    The water quality of the acid ponds in the Niederlausitz brown coal mining region is characterised by pH values below 3 and high concentrations of dissolved iron (up to 10 mM) and sulphate (up to 30 mM). The development of these ponds is determined by the equilibrium that arises between acidifying and alkalinising processes. Acidity develops through weathering and oxidation of iron sulphides in the mining refuse, whereas alkalinity arises through the reduction of iron (III) and sulphate in the pond sediments, a process associated with the oxidation of organic matter. The purpose of the present study was to examine the influence of sulphate reduction and sulphur oxidation on the neutralising potential of the sediments in acid ponds and to characterise and identify the microorganisms involved in these processes. Comparative explorations were performed in two acid waters, namely ponds 111 and 107, and in a neutral water, namely pond B, in a semi-natural area of the Niederlausitz region. [German] Die Wasserqualitaet der sauren Bergbau-Restseen im Braunkohlerevier der Niederlausitz ist durch pH-Werte unter pH 3 und hohe Konzentrationen an geloestem Eisen (bis zu 10 mM) und Sulfat (bis zu 30 mM) gekennzeichnet. Die Entwicklung der Restseen wird durch das Gleichgewicht von aziditaets- und alkalinitaetsbildenden Prozessen bestimmt. Aziditaet entsteht bei der Verwitterung bzw. der Oxidation der Eisensulfide im Kippmassiv, waehrend Alkalinitaet bei der an die Oxidation organischer Substanz gekoppelte Reduktion von Eisen(III) und Sulfat in den Sedimenten der Seen gebildet wird. In der vorliegenden Arbeit wurde der Einfluss der Sulfratreduktion und der Schwefeloxidation auf das Neutralisierungspotenzial der Sedimente der sauren Restseen untersucht sowie die an diesen Prozessen beteiligten Mikroorganismen charakterisiert und identifiziert. Vergleichende Untersuchungen wurden in zwei sauren, Restsee 111 und 107, und in einem neutralen Gewaesser, Restsee B, im naturnahen Bereich

(4) Die Geschwindigkeitsdispersionen der Komponenten im Kern sind im PG entlang der Sichtlinie kurzzeitig stark erhöht, sie fallen ebenso wie die Dichten und deren Verhältnis mit jedem PG stufenförmig ab; einiges davon sind nur Projektionseffekte. (5) Der radiale Verlauf der Geschwindigkeitsdispersion ist vom Bahnort abhängig er wurde genau untersucht. (6) Der Satellit zerfällt über einen Kreislauf aus Massenverlust, flacher werdendem Potential und kleiner werdendem Gezeitenradius. Equilibrium models of one- and two-component satellite galaxies are created. The tidal influence of the Milky Way, which is modeled as a rigid external potential, is examined. A first set of simulations adopting originally spherically-symmetric, one-component satellites show that after elliptical deformation, a bar and tails of unequal length arise which change their morphology cyclically. By considering comparative simulations, the following phenomena are discovered: (1) High-density regions in the tails, (2) low-density zones around the core or bar, (3) an often concealed bar. The overall morphology as function of time is analysed. The particles are lost from the core via the bar and move along certain morphologically characteristic structures into the tails. After deducing general quantities of the multi-component King model, three stable standard models of two-component satellite galaxies with different distributions of dark and visible matter are found. These models have a mass ratio of 1:10 for baryonic to dark matter. Without restriction to the universality of the results, the Large Magellanic Cloud was taken as basic prototype for these models. To choose the proper orbits, the tidal radius of the three-component model of the potential of the Galaxy is calculated both analytically and numerically. Then the simulations are analysed with the different behaviour of the components being the main focus of interest. Main results: (1) It is possible to detach a large

    In the present paper the author reports on the continuation of an OEKOR part project in which he had undertaken a chemical characterisation of emissions from domestic brown coal combustion. On the basis of a partitioning by land use of the Greater Leipzig region he initiated long-term observations of local pollution levels for the various structural types of land. The aim of the work was to facilitate a comprehensive analysis of local air quality in terms of VOC levels. The current concern about VOCs results from the toxicological risk they have been proven to pose to the human organism and from their relevance to the chemistry of the atmosphere (e.g., as precursors of ground-level ozone and other oxidising agents). The task to be accomplished was broken down into the following main steps: Development and trial of a sampling and analysis method for determining an as wide a spectrum of environmental VOCs as possible; elaboration of a measuring strategy for obtaining results of high representativeness and power; installation and operation of pollution monitoring sites in selected structural types of area characteristic of Leipzig; execution of measuring campaigns of several weeks each at selected sites during both winter and summer periods. (orig./MSK) [Deutsch] In Fortsetzung eines vom Berichterstatter bearbeiteten OeKOR-Teilprojekts zur chemischen Charakterisierung von Emissionen aus dem Hausbrand von Braunkohle galt es, auf der Basis einer an der Flaechennutzung ausgerichteten Untergliederung der Stadtregion Leipzig in unterschiedliche Strukturtypen langfristige Immissionsbeobachtungen zu beginnen mit dem Ziel, eine Zustandsanalyse des Umweltmediums Luft bezueglich des Gehalts an fluechtigen organischen Verbindungen (VOC) in ihrer gesamten Breite zu ermoeglichen. Das verstaerkte Interesse an diesen Verbindungen resultiert aus dem fuer eine Reihe von VOC belegten toxikologischen Gefahrenpotential fuer den menschlichen Organismus sowie ihrer atmosphaerenchemischen

    The aim of the environmental epidemiologic study was to determine possible negative effects on the health of children in the very polluted areas of Bitterfeld and Hettstedt in comparison to the less polluted areas of Anhalt-Zerbst (Eastern Germany). The time changes of the health parameters were recorded along with the running redevelopments during the time period of 6 years. The study design consisted of three repeated regional cross sectional studies in 1992/93, 1995/96 and 1998/99. In all, there was information of 7.611 questionnaires to be analysed (participation rate: 89%, 75% and 75%). Children living in the most polluted area of Hettstedt had a noticeable higher risk for non allergic respiratory diseases and symptoms compared to children living in the control area of Anhalt-Zerbst. During the time of the examinations in 1992 till 1999 a clear statistically significant decrease in the prevalences of these restrictions of health could be shown. Children without indoor pollutants in their homes profited most by the improvement of ambient air quality. The better lung function (FVC, FEV{sub 1}) between 1992 and 1999 underlines the improvement of the respiratory health. Children living in both polluted ares have allergies more often (physician's diagnosis, symptoms, allergy specific antibodies). The incidence of asthma, the bronchial hyperreactivity and atopic exzema increased, the prevalence of rhinitis and allergic sensitization did not increase. The body burden with lead and cadmium was higher in children living in polluted areas, but it decreased during the period of observation. In 1997, however, the lead concentration in blood increased a little, parallel to the higher lead concentration in settled dust in Hettstedt at that time. (orig.)

    The composition, reactivity and stability of reactive organic carbon compounds adsorbed on geogenic matrices was investigated. The surface deposits of NOM and its dependence on geochemical parameters was investigated in selected geomatrices. The retention of toxic heavy metals on these surface deposits of NOM was investigated in consideration of the presence of hydroxy species and inorganic ligands. The investigations of the reactivity of the NOM species requires analyses of these compounds and of the heavy metals in the ultratracer region. This was possible by means of radiochemical methods that were further developed in the context of this project. Radioactive labeling of identified reactive carbon compounds, e.g. with radioactive iodine, on the one hand, and the use of radioactive Cu, Pb, Hg isotopes on the other hand enabled speciation analyses in the binary systems (heavy metal + geomatrix, heavy metal + reactive carbon compounds, reactive carbon compounds + geomatrix) and especially in the ternary system (heavy metal + geomatrix + reactive carbon compounds) in defined conditions. The special labelling techniques were a precondition for distribution measurements in the near-natural, low concentration range. (orig.) [German] Ziel des Projektes war es, mit der vorhandenen Analytik und Expertise die Zusammensetzung, die Reaktivitaet und die Stabilitaet der auf den geogenen Matrizes sorbierten reaktiven organischen Kohlenstoffverbindungen und die damit verbundenen Stoffumsaetze aufzuklaeren.

Unter der Beruecksichtigung der Gegenwart von Hydroxyspezies und anorganischen Liganden wurde die Retention toxischer Schwermetalle an diesen Oberflaechendepositen des NOM untersucht.

    Incidental cardiovascular findings are a frequent phenomenon in computed tomography (CT) examinations. As the result of a dedicated PubMed search this article gives a systemic overview of the current literature on the most important incidental cardiovascular findings, their prevalence and clinical relevance. The majority of incidental cardiovascular findings are of only low clinical relevance; however, highly relevant incidental findings, such as aortic aneurysms, thromboses and thromboembolic events can also occasionally be found, especially in oncology patients. The scans from every CT examination should also be investigated for incidental findings as they can be of decisive importance for the further clinical management of patients, depending on their clinical relevance. (orig.) [German] Inzidentelle kardiovaskulaere Befunde sind ein haeufiges Phaenomen bei CT-Untersuchungen. Mit dieser Arbeit soll nach gezielter PubMed-Recherche ein systematischer Literaturueberblick ueber die wichtigsten kardiovaskulaeren Zufallsbefunde sowie deren Haeufigkeit und klinische Relevanz gegeben werden. Die Mehrzahl der inzidentellen kardiovaskulaeren Befunde sind klinisch nur von untergeordneter Bedeutung, allerdings werden immer wieder auch hochgradig relevante Zufallsbefunde wie beispielsweise Aortenaneurysmata oder - gerade bei onkologischen Patienten - Thrombosen und thrombembolische Ereignisse detektiert. Jede CT-Untersuchung sollte gezielt nach inzidentellen Befunden durchsucht werden, da diese je nach klinischer Relevanz von entscheidender Bedeutung fuer das weitere klinische Management des Patienten sein koennen.

    In the borderline region between hydraulic engineering and turbine technology, a wide range of conjectures on cause-effect relationships in connection with turbine inflow have existed for quite some time. It is remarkable that these conjectures, which are partly based on observations and `a feeling for hydraulics`, have not as yeet been subject to scientific scrutiny. This is more the remarkable when one considers the requirements specified by turbine manufacturers concerning the quality of the intake flow based upon such uncertain conjectures. However, extensive contructional measures are sometimes necessary to satisfy these requirements, which are also formulated in general terms in numerous publications. Within the scope of this treatise the new investigations in this field - at a model and a turbine test rig - concentrate on the separating pier, the trash rack and the adjoining convergence channel in the intake region of bulb turbines. The experimental results serve to clarify a number of relationships, partly negate or confirm previous assumptions and relativize some of the requirements. Although the results must be assessed in the light of model-specific restrictions and the characteristics of the turbines tested, they are nevertheless generally applicable to a certain degree owing to the wide scope of the investigations. (AKF) [Deutsch] Im Grenzbereich zwischen Wasserbau und Turbinentechnologie besteht seit geraumer Zeit zu Fragen der Turbinenanstroemung eine Reihe von Vermutungen ueber Ursache-Wirkung-Zusammenhaenge.

Das ist um so bemerkenswerter, als auf der Grundlage solcher unsicheren Vermutungen seitens der Turbinenhersteller nun Anforderungen an die Stroemungsqualitaet im Einlaufbereich erhoben werden.

    Lignite samples of diffrent lithotypes and composition from opencast mines of Lusatia and the region near Leipzig were submitted to weathering processes in laboratory scale experiments and the transfer of organic matter from lignite into the hydrosphere has been observed. By means of high-performance liquid chromatography/electrospray mass spectrometry used in combination with data from gas chromatography/mass spectrometry numerous lignite-derived aromatic and heteroaromatic (poly-)carboxylic acids as well as aliphatic dicarboxylic acids could be characterized in the aqueous extracts. Investigations on water samples from lignite mining residue lakes cofirm these results. Furthermore, formation of chlororganic compounds like polychlorinated dibenzo-p-dioxine and furans (PCDD/F) and polychlorinated biphenyls (PCB), benzenes (PCBz) and phenols (PCPh) has been investigated on different lignite samples under natural weathering conditions and thermal treatment.

    For the purpose of establishing an inventory of environmental medicine data for the eastern Lands of Germany (of the former GDR), field studies have been carried out in the strongly polluted districts of Bitterfeld and Hettstedt and in a low-pollution control district, around Zerbst. The data were intended to reveal the environmental pollution level in various districts and regions, and to indicate regions of priority for immediate research activities to be initiated. The report covers the results compiled in the first project period, in 1992 and 1993. The data presented are for the most part tabulated data taken from the Final Report of the Bitterfeld Study (Heinrich et al.; 1994). Some tables of immunological parameters have been modified. These data are supplemented by data on internal heavy metal concentrations.

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

    This synopsis focuses on the toxic effects of ozone in humans and animals following inhalation. It is limited to studies that deal exclusively with ozone. These studies are reviewed with respect to action mechanisms underlying ozone-specific toxicity and, where present, dose-effect relationships. Both aspects today are indispensable for any risk assessment. As there have been very many studies on this issue and the number of publications increases every year, the present paper only quotes a few review articles and does not mention original papers unless they are of recent date or offer new information. [German] Diese Uebersicht konzentriert sich auf die toxischen Effekte von Ozon nach Inhalation bei Mensch und Tier. Nur Untersuchungen mit Ozon alleine werden miteinbezogen. Sie werden hauptsaechlich im Zusammenhang mit dem Wirkungsmechanismus der Ozon-bedingten Toxizitaet und, soweit vorhanden, Konzentrations-Wirkungsbeziehungen behandelt. Beide Aspekte sind heute fuer eine Risikoabschaetzung unerlaesslich. Da sehr viele Untersuchungen vorliegen und die Zahl der Veroeffentlichungen jaehrlich ansteigt, sollen hier nur einige neuere Uebersichtsarbeiten zitiert werden und Originalarbeiten nur dann erwaehnt werden, wenn sie neueren Datums sind bzw. zusaetzliche Informationen bringen.

    As a result of the Chernobyl fallout some parts of the free state of Saxony were contaminated with radioactive caesium. Based on published maps of the soil contamination and on additional investigations some regions of elevated contamination could be localized. Parallel to soil investigations a game monitoring to wild boars and roe deer was performed. For both types of game typical seasonal variations of contamination were found. In Saxony only the contamination of wild boars is important. In the south of the Vogtland a region was found, where in all seasons the recommended high value of 600 Bq/kg was exceeded in game. In this region the investigation on radiocaesium is now obligatory for wild boars. The hunter can combine this analysis with the analysis on trichina. After three years measurements the region for obligatory analysis was adapted and expanded to neighbouring counties.

    Traveling with mobile homes gains more and more importance in the mobile world. Very dif-ferent regions are visited during any seasons. A basic premise is the maintenance of a comfortable climate in-side the vehicle. In the context of a research program the thermal and energetic behaviour of mobile homes and the thermal-hygric behaviour of the exterior building elements were investigated subject to the surrounding climate, the user's behaviour and the building elements.

    Purpose: Evaluation of image quality of paper prints in routine CT investigations. Method: The image quality of paper prints from 104 CT scans of daily routine investigations was analysed by three observer three observers according to a five-point ranking scale for contrast, grey level, spatial resolution, and subjective confidence in correct evaluation. Each study was rated ''acceptable'' or ''not acceptable for documentation''. Results: In 312 ratings the mean grade for contrast was 2.7, for grey levels 3.2, and for spatial resolution 3.3. Grades ranged from 1 = very good to 5 = insufficient. Subjective confidence in correct evaluation was rated as ''certain'' in 77.4%, ''likely'' in 18.4% and ''impossible to evaluate'' in 4.2% of cases. 93.7% of printed CT images were rated ''acceptable for documentation''. Conclusion: Image quality of paper prints does not reach the quality of laser films concerning its contrast, grey levels, and spatial resolution. Nevertheless, paper prints are acceptable for documentation of findings in most CT investigations. A high confidence in correct evaluation was found. Limitations are found in documentation of small coin lesions of the lung and ischemic lesions of the neurocranium. (orig.)

    In a cooperation project of the Institute of Process Engineering and Power Plant TEchnology (IVD) at the University of Stuttgart and the BASF AG, investigations of co-combustion of plastic material in a coal dust furnace were carried out. The central question of the research work was the ignition and burnout of the particles in dependence of the residence time in the hot part of the furnace. Particle sizes were varied with the aim to define the largest possible particle size in order to minimize the cost of fuel preparation by grinding. On the other hand, tests were made with pure materials and synthetic mixtures of these in order to characterize the influence of different types of plastic. The investigations showed that plastics are suited as fuels for coal dust furnaces, and that the cost of fuel preparation can be reduced to an acceptable level. With polyethylene, which is difficult to ignite, an upper particle size limit of 1.25 to 1.5 mm was reached in the IVD test stand. In industrial applications with a different burner arrangement, even better results may be expected.

    The value of MR imaging for the detection of hyaline cartilage lesions using 2-D spin-echo and 3-D gradient-echo imaging was evaluated in an animal experiment in 10 dogs and in a clinical study in 30 patients. MR imaging findings were compared with histopathological and arthroscopy findings, respectively. Using MRI neither grade I nor grade II hyaline cartilage lesions were detectable. In the animal experiments 77% of grade III lesions and all the grade IV lesions were seen. However, in the clinical study only about the half of grade III and IV lesions were detected. 3-D gradient-echo MR imaging was superior to 2-D spin-echo imaging (p<0.001), while 3-D FLASH and 3-D FISP did not differ significantly in the detection rate (p<0.34). 3-D gradient-echo MR imaging seems to be the best method for the delineation of high grade cartilage lesions. However, early stages of cartilage degeneration are invisible even with this imaging modality. (orig.)

Die kernspintomographischen Ergebnisse wurden mit dem pathologisch-anatomischen Befund bzw. der Arthroskopie verglichen. MR-tomographisch konnten weder Grad-I- noch Grad-II-Knorpellaesionen erfasst werden. Die Erkennbarkeitsrate der Grad-III- und -IV-Laesionen lag fuer die tierexperimentellen Untersuchungen bei 77 bzw. 100%, waehrend klinisch nur etwa 50% dieser Veraenderungen erkannt werden konnten. Dabei waren die 3-D-Gradienten-Echo-Sequenzen den 2-D-Spin-Echo-Sequenzen signifikant ueberlegen (p<0,001), waehrend sich die 3-D-Gradienten-Echo-Sequenzen FISP und FLASH nicht voneinander unterschieden (p<0,34). Derzeit muessen die 3-D-Gradienten-Echo-Sequenzen als die beste Methode zur Erfassung hoehergradiger Knorpellaesionen angesehen werden. Fruehe Stadien der Knorpelschaedigung sind

    In rats, primary peripheral lung tumors composed predominantly of alveolar type II cells have been induced by inhalation of {alpha} quartz. In our retrospective study we evaluated lung specimens of 153 Wistar rats from larger experiments, which had been exposed to quartz by inhalation (10 mg/m{sup 3}, 56 weeks, 5 days/week, 7 h/day: n=27) or intratracheal instillations (5 mg: n=38; 20 mg: n=10; 50 mg: n=28; 15x3 mg: n=25). Animals were sacrificed 1-32 months after administration. For identification of an increased proliferation of alveolar type II cells the DNA content was monitored by microscopic (static) cytophotometry in histological slides. The agryophil (AgNOR) method for the demonstration of nuclear organizer region (NOR) was used as second marker of type II cell proliferation. Morphomtrical measurements were carried out for quantitative analysis of silicosis and quartz dust induced bronchiolo-alveolar hyperplasia of the lung. Summarizing our results, intratracheal instillation and inhalation of quartz in rats regularly induces alveolar proteinosis in combination with a dose- and time-dependent increase of the type II cell proliferation rate as well as an multifocal adenomatous hyperplasia (bronchiolo-alveolar hyperplasia). As nitrogenesis increases carcinogenesis both of them might be prerequisites for enhanced tumor development. (orig.)

    The oxidative CYP2E1-catalyzed dechlorination of dichloremethane (DCM) is a saturable pathway with high affinity and low capacity. In general, due to increasing DCM concentration in the inhaled air COHb values up to 12% are expected, but higher COHb levels were found according to some case reports. It was the aim of this study to characterize the DCM-derived COHb formation and to test effects of DCM on the cardiovascular system using animal models. The results show that a high CYP2E1 activity correlates with enhanced COHb formation. The COHb formation is inhibited and the DCM level in the blood enhanced after simultaneous exposure to DCM and solvents or drugs known as substrates of CYP2E1. Therefore, the risk assessment of DCM exposure must comprimise a possible additional uptake of a substrate or inducer of CYP2E1. Existing PBPK models proved to be an insufficient description in cases of an accidental scenario, a short exposure to very high concentration of DCM. The moderate CO hypoxia following DCM exposure is determined not only by the carboxyhemoglobinemia but also by an inhibition of cytochrome c oxidase activity. Cardiovascular dysfunctions, mainly arrhythmias, are detectable after exposure to relatively high DCM concentration as well as under pathophysiological conditions which per se influenced the cardiovascular system. (orig.) [Deutsch] Die zu CO fuehrende oxydative, CYP2E1-katalysierte Dechlorierung von Dichlormethan (DCM) verfuegt ueber eine hohe Affinitaet bei begrenzter Kapazitaet, es handelt sich um einen saettigbaren Stoffwechselweg.

Vergiftungsfaelle mit weitaus hoeheren COHb-Spiegeln wurden aber beschrieben. Ziel der tierexperimentellen Untersuchungen war es, die DCM-bedingte COHb-Bildung naeher zu charakterisieren und die Wirkung von DCM auf kardiovaskulaere Funktionen zu pruefen.

    Electrocardiogram-gated (ECG) computed tomography (CT) investigations can be accompanied by high amounts of radiation exposure. This is particularly true for the investigation of patients with unclear and acute chest pain. The common approach in patients with acute chest pain is standard spiral CT of the chest. The chest pain or triple-rule-out CT protocol is a relatively new ECG-gated protocol of the entire chest. This article reviews and discusses different techniques for the CT investigation of patients with acute chest pain. By applying the appropriate scan technique, the radiation exposure for an ECG-gated protocol must not necessarily be higher than a standard chest CT scan Aortic pathologies are far better depicted by ECG-gated scan protocols and depending on the heart rate coronary artery disease can also be detected at the same time. The use of ECG-triggered scans will not support the diagnostics of the pulmonary arteries. However, in unspecific chest pain an ECG-triggered scan protocol can provide information on the differential diagnosis. (orig.) [German] EKG-getriggerte CT-Untersuchungen koennen mit einer relativ hohen Strahlenexposition einhergehen.

    In the context of a BMBF-funded project (1994 - 1996), concentrations and behaviour of microorganisms in hydrogeothermal water in Mecklenburg-Vorpommern were investigated. About 50 bacterial strains were isolated and characterized with respect to their cell morphology and relevant physiological properties. A relationship was found between bacterial cells and precipitation products. However, the methods of investigation could not differentiate between biogenic (biochemical) and chemical precipitation products, although the bacterial activity seems to be correlated with the precipitation of organic material.

    Authigenic clay minerals strongly influence the quality of geothermal reservoir systems. Their precipitation may drastically change the properties of reservoir sandstones. They interact more strongly with non-equilibrium fluids than most other mineral phases. The most abundant clay minerals in geothermal wells of Northeastern Germany are kaolinite, illite and mixed-layer minerals. Experiments are being carried out to study the dissolution rates of these minerals in NaCl brines at different pH-values. (orig.)

    The work reported was to investigate the changes caused at the crack tip of a specimen with incipient crack and to assess their effects with regard to component fracture. The steels selected for testing are the pressure vessel steels 10MnMoNi5-5 and 17MoV8-4, and the experiments were made with CT-25 specimens. The conclusion drawn from the results obtained is that the WPS effect is due to a stronger energy dissipation in the prestressed area ahead of the crack tip, assisted by intrinsic stress-induced crack closing.

    Functional magnetic resonance imaging uses the blood oxygen level-dependent effect (BOLD MRI) for noninvasive display of cerebral correlatives of cognitive function. The importance for the understanding of physiological and pathological processes is demonstrated by investigations of working memory in schizophrenics and healthy controls. Working memory is involved in processing rather than storage of information and therefore is linked to complex processes such as learning and problem solving. In schizophrenic psychosis, these functions are clearly restricted. Training effects in the working memory task follow an inverse U-shape function, suggesting that cerebral activation reaches a peak before economics of the brain find a more efficient method and activation decreases. (orig.) [German] Die funktionelle Magnetresonanztomographie (fMRT) nutzt den ''blood oxygen level dependent effect'' (BOLD-Effekt) zur nichtinvasiven Darstellung zerebraler Korrelate kognitiver Funktionen. Die Bedeutung dieses Verfahrens fuer das Verstaendnis physiologischer und pathologischer Prozesse wird anhand von Untersuchungen zum Arbeitsgedaechtnis bei Schizophrenen und gesunden Kontrollpersonen verdeutlicht. Das Arbeitsgedaechtnis dient weniger der Speicherung, sondern vielmehr der Verarbeitung von Informationen und ist deshalb in komplexe Prozesse wie Lernen und Problemloesen eingebunden. Im Rahmen schizophrener Psychosen kommt es zu einer deutlichen Einschraenkung dieser Funktionen. Erwartungsgemaess zeigen sich unter Durchfuehrung eines Arbeitsgedaechtnisparadigmas Unterschiede in der zerebralen Aktivitaet, die jedoch bei den Erkrankten unter Therapie prinzipiell reversibel sind. Von Interesse sind auch Trainingseffekte bei Gesunden, wobei eine verminderte Aktivierung nach Training auf eine ''Oekonomisierung'' schliessen laesst. (orig.)

[German] Die Bestrebungen einer effizienten und schadstoffarmen Energieversorgung fuehrten bei der Kohleverbrennung zur Entwicklung von kohlebasierten Kombikraftwerken, die im Vergleich zum konventionellen Kondensationskraftwerk eine deutliche Anhebung des Nettowirkungsgrades erlauben. Eines der Kombikraftwerkskonzepte auf Kohlebasis stellt die Druckkohlenstaubfeuerung dar, die gegenueber den anderen Konzepten das hoechste Wirkungsgradpotential aufweist. Das Ziel dieses Forschungsvorhabens war die Gewinnung gesicherter Erkenntnisse hinsichtlich des Feuerungsverhaltens von Kohle in einer Druckkohlenstaubfeuerung. Es wurden an einem Druckflugstromreaktor detaillierte Untersuchungen zur Brennstoffumsetzung und zum Partikelverhalten, zur Schadstoffbildung und zum Werkstoffverhalten unter Bedingungen der Druckkohlenstaubfeuerung durchgefuehrt. Im Laufe des Forschungsvorhabens wurden einige neue Messtechniken eingesetzt und teilweise auch angeschafft, wie zum Beispiel ein Zwei- Farb-Pyrometer zur simultanen Erfassung von Partikeloberflaechentemperatur und Partikeldurchmesser von brennenden Brennstoffpartikeln. Parallel zu den experimentellen Untersuchungen wurde an der Erarbeitung neuer Berechnungsmodelle gearbeitet, um eine spaetere Feuerraumsimulation fuer ein verbessertes Scale-Up zu ermoeglichen. Die am Druckflugstromreaktor gewonnenen Ergebnisse zeigen, dass der erhoehte Systemdruck sich auf sehr viele Verbrennungsmechanismen stark auswirkt, so konnte eine schnellere Brennstoffumsetzung und gleichzeitig verminderte Stickoxid- und Alkaligasemission nachgewiesen werden. Die Werkstoffuntersuchungen zeigten, dass die aufgrund der sehr hohen Verbrennungstemperaturen benoetigten Keramikwerkstoffe sehr empfindlich gegenueber Verschlackung und schnellen Temperaturwechseln sind, weshalb hinsichtlich der benoetigten Standzeiten in einer zu realisierenden Druckbrennkammer noch erheblicher Entwicklungsbedarf besteht.

    In several aspects, the behaviour of aircraft wake vortices under situations of vertical wind shear is significantly different from non-shear scenarios and its operational real-time forcast is challenging. By means of numerical investigations of idealized scenarios, the influence of wind shear on the lateral and vertical transport of vortices is analysed both, phenomenologically as well as in the scope of a sensitivity study. The results allow for the verification of controversial views and the benchmark of modelling approaches. Case studies of turbulent shear flows focus on the persistence of vortices. A detailed analysis of the flow fields evidence that unequal vortex decay rates can be attributed to the asymmetric distribution of secondary vorticity structures. The results moreover suggest that extended vortex lifespans can be expected under situations of wind shear. The unusual vortex behaviour observed by means of a LIDAR measurement is reproduced by realistic simulations and permits to reveal potential causes. (orig.) [German] Das Wirbelschleppenverhalten unterscheidet sich in Situationen vertikaler Windscherung in mehrfacher Hinsicht signifikant von scherungsfreien Szenarien und stellt eine besondere Herausforderung fuer eine operationelle Echtzeitvorhersage dar. Mittels numerischer Untersuchungen idealisierter Szenarien wird zunaechst der Einfluss von Windscherung auf den lateralen und vertikalen Wirbeltransport sowohl phaenomenologisch als auch quantitativ im Rahmen einer Sensitivitaetsstudie analysiert. Anhand der gewonnenen Ergebnisse werden auseinandergehende Erklaerungsansaetze geprueft und Modellierungsansaetze bewertet. Fallstudien turbulenter Scherstroemungen zur Wirbelpersistenz stellen einen weiteren Schwerpunkt dieser Arbeit dar. Durch die ausfuehrliche Analyse der Stroemungsfelder wird der Nachweis erbracht, dass sich unterschiedliche Zerfallsraten der Wirbel auf die asymmetrische Verteilung von sekundaeren Vorticity-Strukturen zurueckfuehren

    In the past, the environmental situation in the industrial agglomeration of Bitterfeld/Wolfen was characterized by extremely high pollution of the atmosphere, for instance with fly ash, sulfur dioxide, nitrogen monoxide and chlorinated hydrocarbons, by water pollution and soil pollution. In the Hettstest area, by contrast, heavy-metal pollution from decades of mining activities and emissions from the nonferrous heavy metals industry was most prominent.- The study, which was sponsored by the Federal Environmental Agency, aimed to establish possible health hazards to the public in these two centres of pollution in comparison with the little polluted control territory of Zerbst. These hazards are quantified in terms of the long-term effect of high atmospheric pollution in the Bitterfeld and Hettstedt regions. In addition, changes in health parameters as a function of time are recorded for a six-year period concomitantly to ongoing redevelopment measures. This will permit necessary policy adjustments.- As during the first survey in 1992/93, the health checks were done by physicians and nurses at schools, nursery-schools, Public Health offices and, in part, in special vehicles equipped with pulmonary function test units. All health checks were done according to the same standardized specifications, using the same devices, and by the same investigators.- Information was requested from the children`s parents regarding illnesses and symptoms, especially respiratory tract diseases and allergies, and regarding sociodemographic aspects and characteristics of the children`s domestic environment that might bear on the results. Their pulmonary function was measured in body plethysmographs and their respiratory tract sensitivity was measured prior to and after cold air provocation. Skin prick tests to determine major inhalative and food allergens and blood tests for specific antibodies complemented the information on possible allergic diseases.- Further, hematological parameters

    Room air quality is highly important in Germany as people living here will spend 90 percent of their lives inside rooms. Air quality is defined to a large extent via the nose. This research project, in continuation of AiF 10525, involved investigations of materials and components of space HVAC systems with varying air temperatures, humidities and air flow rates for a subjective assessment of the air quality. The main goals were the definition of laws for identification of odorants and the derivation of laws for calculating pollutant-level-dependent ambient air rates for mechanically ventilated rooms. The experiments showed that both adsorption and desorption had a significant part in the addition of odorangs, causing deviations between theoretical and experimental values of felt air quality. The temperature and the relative humidity had an effect as well. Most measurements were made near the olfactory threshold, so that a number of participants were unable to complete the test. Later investigations will rely on analytical methods in addition to test persons. (orig.)

    46 patients with avascular necrosis of the femoral head were examined by T[sub 2]- and T[sub 1]-weighted MR before and after infusion of Gd-DTPA. Both sides were involved in 12 cases. The classification was done according to Ficat. In early stages and in postoperative studies a correlation of signal intensity after infusion of Gd-DTPA and clinical symptoms was found. Hyperintensity of the avascular area or of the implanted material was assumed to be vascularised or vital components in 4 cases of Ficat 1 and 15 postoperative studies. Contrariwise, we found in 5 patients with severe postoperative symptoms, low signal intensity areas due to avascular regions. (orig.).

    In this dissertation the development of a simulation strategy is presented, which enables a detailed description of relevant regions to appropriately model the electroslag remelting process. One of the challenges is to ensure a sufficient efficiency of the numerical model so that it can be used to perform extensive parametric studies. This is achieved by combining multiple computational domains and coupling the simulation codes ANSYS FLUENT and ANSYS EMAG. Therefore the electroslag remelting process is divided into a droplet simulation and models that account for the fluid flow in the slag and fluid flow and solidification in the metal pool. The droplet simulation considers the multiphase flow and the interaction of fluid flow and magneto hydrodynamics to simulate the behavior of the metal droplets passing through the slag layer. The Lorentz force is the main driving force for the fluid flow established in the slag region, which causes the liquid metal film on the electrode's bottom surface to be transported to the centerline. Therefore it was found that no metal droplets detach near the electrode's edge. Instead they accumulate at a certain characteristic radius. Between this radius and the centerline metal droplets form and detach homogeneously. The fluid flow in the slag region is directed to the centerline near the electrode's bottom surface, points downwards on the centerline, moves outwards near the phase boundary to the metal pool and is directed upwards at the surface of the copper mold. In the case of the smaller scale IME remelting plant, metal droplets only occur on the centerline. The steady state simulation of the electroslag remelting process developed during this work introduces a static phase boundary, which separates the slag and the metal region. The formulation of the static phase boundary drastically reduced the time required until convergence is achieved. The simulation model has been extensively validated by comparing the

    ] Obwohl das Wissen um die Bedeutung von luftgetragenen Partikeln fuer die Strahlungsbilanz der Atmosphaere in den letzten Jahren zugenommen hat, sind eine Reihe von wichtigen Aerosolbildungsmechanismen bisher nur unzureichend untersucht worden. Dies gilt insbesondere fuer Aerosole, die aus fluechtigen organischen Vorlaeufern natuerlichen wie auch antrophogenen Ursprungs im Verlauf von troposphaerischen Oxidationsprozessen gebildet werden. Das Vorhaben umfasste daher die Entwicklung massenspektrometrischer Methoden fuer qualitative wie auch fuer quantitative Studien zur chemischen Zusammensetzung von sekundaeren organischen Aerosolen (SOA), insbesondere gebildet aus der Ozonolyse von Monoterpenen (z.B. {alpha}-Pinen, {beta}-Pinen, Sabinen, {delta}{sup 3}-Caren, Limonen). Mit Hilfe eines entwickelten On-line APCI-ITMS-Systems (atmospheric pressure chemical ionisation, APCI) konnte die Bildung von Gas- und Partikelphasenprodukten in Echtzeit (Zeitaufloesung {proportional_to}1 s) als Folge der Monoterpen-Ozonolyse beobachtet werden. Die Nachweisgrenze der Methode liegt bei ca. 100 ppt(v/v) im positiven Ionenmodus. Basierend auf der Entwicklung geeigneter Standardadditionsmethoden erfolgte auch die unmittelbare Quantifizierung ausgewaehlter Oxidationsprodukte in der Gas- und Partikelphase. Mittels isotopenmarkiertem Wasser (H{sub 2}{sup 18}O) wurden darueber hinaus einige zugrundeliegende Reaktionsmechanismen aufgedeckt. Ein weiterer Teil des Projektes konzentrierte sich auf die Charakterisierung insbesondere der schwerfluechtigen Aerosolkomponenten der Monoterpen-Ozonolyse mittels MS/MS-Studien. Diese Studien ergaben, dass eine Reihe von multifunktionellen Carbonsaeureprodukte signifikante Aerosolbestandteile repraesentieren (Dicarbonsaeuren, Oxocarbonsaeuren, Hydroxycarbonsaeuren etc.). Schliesslich ergaben die massenspektrometrischen Untersuchungen deutliche Hinweise auf starke intermolekulare Wechselwirkungen zwischen den einzelnen Produkten (Assoziatbildung). Da ausserdem

    Aim: Recent in-vitro and in-vivo studies demonstrated a somatostatin receptor expression in some non-medullary thyroid carcinomas. In this study we investigated the somatostatin receptor status for this particular tumor entity in a larger patient group. Subject and methods: We compared 131-iodine with 111-In-pentetreotide scans in 24 patients with metastasizing, non-medullary thyroid cancer. The findings were correlated with other imaging modalities. Additionally, we performed receptor autoradiography in one patient, octreotide therapy in another patient and administration of 90-Y- and 111-In-DOTATOC in 2 consecutive patients. Results: In the 15 patients with papillary or follicular carcinoma, 111-In-pentetreotide was inferior to 131-I in 8/15, equal in 1/15, and superior in 6/15 patients. In 8/9 of the patients with Huerthle cell cacinoma, metastases showed a 111-In-pentetreotide accumulation of various intensity, while 131-iodine scans were negative except for one patient. 111-In-pentetreotide was equal or superior compared to 201-Tl or 99m-Tc-sestamibi, but for the most part inferior in comparison with 18-F-FDG-PET. The findings of 111-In-pentetreotide scintigraphy correlated well with the receptor autoradiography and the accumulation of DOTATOC, but not with the therapeutic effect of `cold` octreotide on the thyroid cancer metastases. Conclusions: Several metastases of papillary and follicular carcinoma, and the majority of Huerthle cell cancer metastases can express somatostatin receptors. 111-In-pentetreotide scintigraphy is a promising tool for localization of metastases especially in Huerthle cell cancer or if PET is not available, and may be useful for selection of possible candidates, if therapeutic effective {beta}-emitting somatostatin analogues will be available for routine application.

    Background: Conformal radiotherapy techniques as used in prostate treatment allow to spare normal tissue by conforming the radiation fields to the shape of the planning target volume (PTV). To be able to fully utilize the advantages of these techniques correct patient positioning is an important prerequisite. This study employing an electronic portal imaging device (EPID) investigated the positioning uncertainties that occur in the pelvic region for different patient positioning devices. Patients and Methods: 15 patients with prostate cancer were irradiated with or without rectal balloon/pelvic mask at a linear accelerator with multileaf collimator (MLC). For each patient multiple portal images were taken from different directions and compared to the digitally reconstructed radiographs (DRRs) of the treatment planning system and to simulation films (Table 1, Figure 1). Results: In spite of different positioning devices, all patients showed comparable total positioning uncertainties of 4.0 mm (lateral), 4.5 mm (cranio-caudal) and 1.7 mm (dorso-ventral). The lateral positioning error was reduced for the pelvic mask patients while the cranio-caudal error increased (Table 2, Figure 2). A systematic and a random component sum up to the total positioning error, and a good estimate of the magnitudes of the two is possible from six to eight portal images (Figure 3). Conclusions: With a small number of portal images it is possible to find out the systematic and random positioning error of a patient. Knowledge of the random error can be used to resize the treatment margin which is clinically relevant since this error differs greatly for different patients (Figure 4). Image analysis with EPID is convenient, yet has some problems. For example, one only gets indirect information on the movement of the ventral rectum wall. The successful operation of positioning devices, although, needs further improvement - especially if one focuses on IMRT. (orig.) [German] Hintergrund

    The condition of beech trees was investigated in six forest stands in the Bayerischer Wald and Boehmerwald mountains between 1995 and 1997 in order to establish the interdependence between tree conditions, the prevailing natural and anthropogenic site factors, and air pollution especially with groundlevel ozone. Details of the investigations are presented. Although a potential long-term effect of ozone cannot be excluded, the damage observed in beech trees in this region since the eighties is assumed to be caused not by a single factor but by complex interaction patterns between several anthropogenic and natural factors. [German] Es erfolgte im Untersuchungsgebiet Bayerischer Wald/Boehmerwald im Zeitraum 1995 bis 1997 eine detaillierte Zustandscharakterisierung von Altbuchen an sechs Standorten. Im Rahmen der Gesamtuntersuchung sollte geklaert werden, ob Zusammenhaenge zwischen dem Baumzustand und den herrschenden natuerlichen und anthropogenen Standortfaktoren und Luftbelastungen mit Schwerpunkt des bodennahen Ozons bestehen. An Hand kontinuierlicher Ozonmessungen konnte bestaetigt werden, dass die Konzentration des bodennahen Ozons im wesentlichen eine Funktion der Meereshoehe ist; somit ist an Hochlagenstandorten von hoeheren Immissionen auszugehen. Bei den moeglicherweise besser an photooxidativen Stress akklimatisierten Hochlagenbuchen waren die Schaeden bei erhoehter Ozonbelastung geringer ausgepraegt als bei Tieflagenbuchen. Fuer die Hypothese, wonach man eine staerkere Schaedigung der Hochlagenbestaende zu erwarten hat, wurde keine Bestaetigung gefunden. Inositol wird seit einiger Zeit als sensitiver Indikator diskutiert, der auf veraenderte Umweltbedingungen reagiert. Die Inositolkonzentration in Sonnenblaettern von Altbuchen im Bayerischen Wald war in 1995 um ca. 50% geringer als in 1996. Bei den Jungbuchen im Phytotronenexperiment kam es bei anhaltendem Ozonstress und zunehmender Schaedigung zu einer starken Reduktion der Inositolkonzentration in

    Aim: a pilote study for estimation of radiation exposure due to diagnostic procedures in nuclear medicine using routine data of hospitals and practices in Germany. Methods: hospitals and practices willing to participate in the study supplied data of one year (1997), containing information on patients' identification number, age, sex, type of diagnostic procedure, radiopharmaceutical, administered activity, type of health insurance (private/public), inpatient/outpatient status, and so-called leistungsziffer, which describes the type of medical performances in Germany. The effective dose per examination was calculated according to ICRP 80. Mean, standard deviation, median, 5{sup th} and 95{sup th} percentiles of the effective dose were calculated, stratified by type of organ system and also by sex and age, including patients of {>=} 18 years. Results: 82 039 examinations from patients of 9 hospitals and practices were analyzed. The median (5-95{sup th} percentiles) of the effective dose per examination for all patients was 2.9 mSv (0.4-8.5 mSv); 1.2 examinations per patient and year were performed on average. The three most frequent examinations were bone scans (median 3.4 mSv; 2.9-5.1), thyroid (0.9 mSv; 0.4-2.2) and cardiovascular studies (7.3 mSv; 3.8-20.2). The median effective dose for 18 to 40 years old women was 1.0 mSv (0.4-5.8), for women between 41 and 65 years 2.2 mSv (0.4-7.3) and for women older than 65 years 2.4 mSv (0.5-7.6). The corresponding values for men were 2.6 mSv (0.3-7.6); 3.3 mSv (0.4-9.1), and 3.4 mSv (0.5-8.8). Conclusion: it was possible to gain an accurate determination of radiation exposure of diagnostic procedures in nuclear medicine by routine data. (orig.)

    The effects of the key flow, mixing and ignition parameters on the ignition process was investigated in near-practical conditions. It was found that the ignition energy can be minimized by careful selection of the electrode configuration and positioning near the burner. Further, a criterion was developed for developing characteristic fields and design specifications for gas burners. The FLUENT code can calculate the mixing, flow and turbulence situation of a burner. This, and plus the newly established ignition criterion, can support the development of characteristic fields and help to minimize the experimental expenditure. [German] Der Einfluss der wichtigsten Stroemungs-, Mischungs- und Zuendparameter auf die Zuendung wurde mit Hilfe gezielter experimenteller und theoretischer Untersuchungen unter industrienahen Bedingungen getestet. Hierbei konnte eine gute Uebereinstimmung zwischen den Messungen und Rechnungen erzielt werden.

Gleichzeitig wurde ein Kriterium entwickelt, das zur Erarbeitung von Kennfeldern und Auslegungsvorschriften fuer Gasbrenner genutzt werden kann. Mit Hilfe des kommerziellen CFD-Programms FLUENT kann die Mischungs-, Stroemungs- und Turbulenzsituation eines Brenners numerisch berechnet werden. Mittels dieser Ergebnisse und unter Anwendung des ermittelten Zuendkriteriums kann die Erstellung von Arbeits- und Zuendkennfeldern fuer die Neuentwicklung bzw.

    The author investigated changes in the hormone metabolism of affected trees; he intended to analyze as many hormones as possible. The investigations were carried out on needles, owing to the fact that the symptoms observed suggested specific disturbances of the needle hormone metabolism. Further, needles are the main point of attack of airborne pollutants. In physiologically healthy trees, the seasonal changes in hormone levels were investigated as a function of different parameters such as forest site, needle age, tree age, and position of sample branches in the tree crown. On this basis, hormone changes resulting from tree disease were characterized for the sample trees. SO{sub 2} and ozone were taken into account in the investigations. It was found that although the development with time of physiological and structural characteristics suggests premature aging of the needles of affected trees, the changes in the hormone metabolism do not correspond to the hormonal control patterns of natural needle aging. SO-2 exposure or a lack of minerals at the forest site are excluded as causes of the observed damage. No conclusive information could be obtained on the effects of ozone.

    From the present report 'Untersuchungen zur Radionuklidfreisetzung und zum Korrosionsverhalten von bestrahltem Kernbrennstoff aus Forschungsreaktoren unter Endlagerbedingungen' with the code number FKZ 9108 carried out in the time periode 01.06.1998 till 30.11.2001 the following results can be withdrawn: U/Al-RR-fuel elements corroded slowly in granite water (Grimsel-West) at 90 C under anaerobic conditions. For a complete dissolution of the fuel element a time period of 10{sup 3} years is assumed according to present conservative results. In salt brines, especially in magnesium chloride rich brines the corrosion rate is high. Addition of GGG40 (basic material of the fuel element container with iron as main element) had an acceleration effect. A complete dissolution of the fuel is achieved within a couple of months. Under aerobic and under anaerobic conditions the bulk of released radionuclides were fixed by the corrosion products formed (secondary phases). The actinides were mobilised by variation of the ionic strength of the leaching solution. This process can be explained by phase conversion reactions within the secondary phases. Secondary phases formed by corrosion of a non-irradiated U/Al-RR-fuel element, were analysed and hydrotalcites were identified as phase components. This result justifies the assumption, that hydrotalcites are components of the corrosion products from irradiated fuels. To clarify the questions which bindings exist between radionuclides and secondary phases, sorption experiments were performed. The sorption experiments were performed in salt brines and in granite water using repository relevant radionuclides and minerals which are considered to represent thermodynamic final components of the secondary phases. Pu sorbed as cationic species quantitatively and the binding is covalent. In granite water the same behaviour was found for Am. (orig.)

    Acting on behalf of the State Hunting Association of Lower Saxony the Game Research Institute (IWFo) of Hannover Veterinary University carried out a three-year study from April 1998 through March 2001 on the habitat use of selected native small game species in the vicinity of aerogenerators. This final report depicts the animals' preferred places, use of agricultural land, avoidance radius, if any, their activities and exposure to predator pressure. The target species were roe deer, hare, red fox, partridge and carrion crow. The study was carried out in Lower Saxony and Bremen on a total study area of 22.3 km{sup 2}, comprising four areas with running aerogenerators and five control areas without an aerogenerator. All parameters were studied in terms of a comparison between aerogenerator and control areas. The objective was to identify differences in population, use of space and habitat and in behaviour. [German] Am Institut fuer Wildtierforschung an der Tieraerztlichen Hochschule Hannover (IWFo) wurde im Auftrag der Landesjaegerschaft Niedersachsen (LJN) in einer dreijaehrigen Studie von April 1998 bis Maerz 2001 die Raumnutzung ausgewaehlter heimischer Niederwildarten im Bereich von Windkraftanlagen (WKA) untersucht. Im Weiteren wurden Aufenthaltspraeferenzen, Nutzung der landwirtschaftlichen Flaechen, moegliche Naeherungslimits und Aktivitaeten der Wildarten sowie der Beutegreiferdruck dargestellt. Zielarten der Studie waren Rehwild, Feldhase, Rotfuchs, Rebhuhn und Rabenkraehen. Die Untersuchungen wurden in vier Gebieten mit in Betrieb befindlichen WKA sowie in fuenf Referenzgebieten ohne WKA in Niedersachsen und Bremen auf einer Flaeche von insgesamt 22,3 km{sup 2} durchgefuehrt. Alle Parameter wurden vergleichend fuer die WKA- und Referenzgebiete betrachtet. Moegliche Unterschiede im Besatz bzw. Bestand, in Raum- und Habitatnutzung sowie im Verhalten wurden herausgearbeitet.

    Stone and other surfaces are still corroded by dry-deposited sulphur dioxide, although the present concentration is in the lower ppbv range. In this work experiments were conducted to separate and assign the different resistances during the deposition process at concentrations of SO{sub 2} found in the environment today. To compare surfaces with different reactivities, the varying uptake and the resulting SO{sub 2} concentration over the surface has to be concerned. Therefore a test chamber has been developed that allows the SO{sub 2} concentration to keep constant independent of the SO{sub 2} uptake. Different stones and passive samplers were investigated in this chamber, scanning a wide range of humidity and concentration that has not been studied before. The passive sampler was also studied in a closed wind tunnel with a sulphur dioxide containing atmosphere. It has been found that the deposition velocity is increasing with decreasing SO{sub 2} concentration for all stone types. (orig.) [German] Alle technischen Oberflaechen unterliegen Alterungsprozessen. Atmosphaerische Schadgase wie Schwefeldioxid tragen zur Korrosion dieser Oberflaechen in erheblichem Umfang bei. Auch wenn insbesondere die Konzentration an SO{sub 2} in der Aussenluft in den letzten Jahren in den unteren ppbV-Bereich gesunken ist, so ist der Anteil und die Potenz dieses Gases am Zerfallsprozess von Natursteinen aufgrund seiner guten Wasserloeslichkeit und der Saeurestaerke noch immer sehr hoch. Dennoch finden sich in der Literatur kaum zuverlaessige Daten ueber die Schwefeldioxid-Aufnahme verschiedener Natursteinvarietaeten. Insbesondere mangelt es an systematischen Untersuchungen der verschiedenen, den SO{sub 2}-Depositionsprozess bestimmenden Faktoren. Ziel dieser Arbeit war es, einen wesentlichen Beitrag zur Schliessung dieser Luecken zu leisten. Dazu wurde ein Messsystem zur Untersuchung verschiedenartiger Gesteinsproben im Labor konzipiert und in Betrieb genommen. (orig.)

    Lysimeter experiments based on the stable isotope tracer technique are a suitable means of examining the complex relationships governing water and material transport processes in the soil. The present paper reports on experiments in which water and nitrate movement was traced directly by means of lysimeters placed at different depths and using deuterium water and [{sup 15}N]N-nitrate for pulse marking. Extensive investigations carried out during the dissection of soil monoliths that had been used for many years in lysimeters offered an opportunity for stable isotope tracer studies aimed at determining seepage water and anion movement in undisturbed soils and, after dismantling the lysimeters, conducting soil analyses to find out more about the fate of nonpercolated tracers at various soil depths. Following other authors, bromide anions were additionally used as conservative tracers. [Deutsch] Zur Untersuchung der komplexen Zusammenhaenge des Wasser- und Stofftransportes im Boden bieten sich Lysimeterversuche unter Nutzung der stabilisotopen Tracertechnik an. In der vorliegenden Arbeit wird zunaechst ueber die direkte Verfolgung der Wasser- und Nitrat-Bewegung in tiefengestaffelten Lysimetern durch Pulsmarkierung mit Deuteriumwasser und [{sup 15}N]Nitrat berichtet. Im Rahmen von umfangreichen Untersuchungen bei der Zerlegung von langjaehrig in Lysimetern genutzten Bodenmonolithen bestand des weiteren die Moeglichkeit, stabilisotope Traceruntersuchungen zur Bestimmung der Sickerwasser- und Anionenbewegung an ungestoerten Boeden durchzufuehren und nach der Zerlegung der Lysimeter ueber entsprechende Analysen des Bodens Aussagen zum Verbleib der nicht perkolierten Tracer in verschiedenen Bodentiefen zu treffen. Zusaetzlich wurde dabei das von anderen Autoren bereits genutzte Bromid-Anion als sogenannter konservativer Tracer eingesetzt. (orig.)

    P.v. represents a ''clinical model'' of diagnostic radionuclide application to evaluate the total and regional perfusion of brain. 107 polycythemians treated by or provided for radiophosphorus were studied by neurologic methods as EEG e.g. and with XCT if necessary. These studies were accomplished repeatedly in 62% of the surveyed patients. We found disturbed perfusion in brain: 32, diminuation of blood flow in vertebral-basilar region: 8, polyneuropathies: 27, psychic abnormalities: 60. Therapeutic effects became ascertained in 34% of hemipareses. The majority of polycythemic patients let recognize a regression of subjective complaints. The diagnostic informations obtained by radionuclide methods were compared to clinical and neurologic results as mentioned above. A good correlation could observed from radionuclide angiography, [sup 133]Xe-studies of total and regional cerebral perfusion and HMPAO-SPECT to neurologic and radiological findings. 66% of studied patients showed abnormal radioactivity distribution at static scintigrams. Disturbances of cerebral perfusion were seen in 20 from 26 patients if radionuclide angiography was used. Especially the inflow to cerebral vessels was found retarded by this method. Even in 3 neurologically inconspicuous persons the cerebral perfusion was restricted. Only 5 patients without signs of decreased flow could be seen. In 9 of 10 cases studied using [sup 133]Xenon referred to diminuation of cerebral perfusion. Both dynamic methods showed changes in perfusion depending from time course. Numerous localized defects of vascularization were detected by SPECT in some corresponding with neurologic symptoms in other patients differing from these ones. (orig./MG)

    Together with polycyclic aromatic hydrocarbons, polychlorinated biphenyls and heavy metals other elements and compounds as well as nutrients are present in typical contaminated areas like sewage fields. They are found as mixed undisturbed contamination and the transfer of these pollutants into food or forage plants is dangerous for people. So far investigations of ecological effects of these substances are focused mainly on single agents or on some agents of the same chemical group. But in most cases the mixture of different chemical compounds in extremely contaminated fields cause synergistic effects resulting in yield reduction and decrease of microbiological activity. Therefore the aim of the present report is to show combined effects of selected organic pollutants (benzo-a-pyren, 2,2`, 5,5` tetrachlorbiphenyl) and heavy metals (cadmium, copper) on parameters of soil biology, biomass production and pollutant uptake by plants. Resulting changes of cellulose decomposition, CO{sub 2}-release from soil and N-mineralization after separated and combined enrichment of weakly polluted sewage field soil with said pollutants up to concentrations of extremely polluted sewage field soils are presented in this paper. Data of yields and pollutant contents of plants (rye, maize and potatoes) cultivated on experimental soils are summarised and ecotoxicological risks resulting form pollutants and their interactions discussed.

In der ersten Untersuchungsserie wurden bei 75 Patienten (Alter 20 bis 65 Jahren; Patientegruppe 1) mit Zephalalgie die HE-Werte der nativen unveraenderten weissen Substanz bestimmt. In der zweiten Patientengruppe befanden sich 20 Patienten mit operierten Gehirntumoren bei denen von Strahlentherapie und nach 10, 20, 30, 40 und 50 Gy die HE-Werte bestimmt wurden. In der dritten Patientengruppe befanden sich 64 Patienten, die wegen eines Gehirntumors bereits operiert worden waren und nun einer postoperativen Radiatio unterzogen wurden. In der zweiten und dritten Patientengruppe wurden die Bestrahlungen teils mit Telekobalt, teils mit Photonen eines Linearbeschleunigers (6 und 9 MeV) durchgefuehrt. Bei der CT-Untersuchungen kam ein Siemens Somatom CR (125 kV, 450 mAs) mit einer Scan-Zeit von 5 s zur Anwendung. In der ersten Patientengruppe stellten wir keine Werte unter 30 HE in der weissen Substanz fest. Die Werte der zweiten Patientengruppe bewegten sich ohne Diuretikagabe zu Beginn der Bestrahlung zwischen 25 und 29 HE. Bei einem Abfall unter 25 HE traten Dauerkopfschmerz, Schwindel und Querulanz auf. In diesen Faellen wurde die diuretische Behandlung so lange gesteigert, bis wieder Werte von 25 bis 29 HE vorlagen. In derm18itten Patientengruppe stellten wir zu Beginn der Radiatio bei 47 von 64 Patienten Werte von 25 bis 29 HE fest. Obwohl jedem Patienten von Anfang an Furosemid verabreicht wurde, verringerten sich bei 28 Patienten die Werte auf 20 bis 24 HE. Eine Verbesserung konnte mit zusaetzlicher Gabe von Glyzerin per os erreicht werden. Daraufhin pendelten sich die Werte auf 25 bis 29 HE ein. Lediglich in einem Fall fielen die Werte unter 20 HE.

    Representatives of the family Myxococcaceae, Myxococcus fulvus and M. virescens as well as Archangium gephyra could be isolated from marine sediments (depth range 5 58 m), collected near the island of Helgoland (North Sea); dunes and rudiments of salt marshes additionally yielded M. coralloides and the rare species Melittangium licenicola and M. boletus (Cystobacteriaceae). In soil samples from the island, M. fulvus, M. virescens, M. coralloides, A. gephyra, Cystobacter fuscus and Stigmatella erecta were found. These results were confirmed by data, obtained from the coastal zone of the island of Amrum and marine sediments from various regions. On the other hand samples from shallow fresh water (depth range 0.3 1 m) proved to be richer in species. It is assumed that the myxobacteria found in marine sediments occur as resting cells.

    The author reports on a number of studies performed on cadmium exposure in the population of the Federal Republic of Germany, in particular that of the Rhine-Ruhr region. The studies covered: - the examinations for Cd concentrations in full blood (CdB), in urine (CdU) in different population groups, and the analysis of various influencing factors; - an autopsy study involving 388 corpses from the Duesseldorf and Duisburg regions to determine the concentrations of cadmium, copper and zinc in the renal cortex - an epidemiological study on the occurrence and incidence of cadmium-induced renal function disorders in inhabitants of areas exposed to high Cd immission levels (Stolberg, Duisburg). The studies indicate CdB concentrations to be influenced by the following factors: - smoking; - age; - sex; - Cd immission level. Measurements of CdU concentrations were performed in children from Duisburg and Goch, and in women aged 65 and 66 from Stolberg, Duisburg and Duesseldorf. The results of the study performed in children did not reveal any influence of Cd immission levels. The results of the autopsy study showed that Cd concentrations in the renal cortex of persons not exposed to heavy metals occupationally, are well below the critical CdKc concentration on an average. The results of the epidemiological study on cadmium-induced renal function disorders in 286 women aged 65 and 66 from the cities of Stolberg, Duisburg and Duesseldorf revealed that no indications for renal dysfunctions clearly attributable to excessive Cd accumulation in the kidney, were verified even in a population group which had been exposed to relatively high Cd levels from the environment.

    The physical phenomena of rotary instabilities in industrial compressors and high-pressure aircraft compressors were investigated, which may be a cause of compressor blade fracture. The investigations were carried out by Duesseldorf Technical University on behalf of Rolls-Royce Deutschland GmbH at the new four-stage low-pressure compressor test stand of TU Dresden University. Extensive measurements were made both in the rotary and stationary system in the third compressor stage. Rotary instabilities could be detected by increasing the clearance between the blade tip and compressor wall. Modal analyses yielded a rate of about 30 for 63 blades, i.e. a characteristic wavelength of about twice the length of a blade. So far, an accurate description of the physical mechanism was impossible. Investigations using a Snubber model showed no significant influence on the rotary instabilities. [German] Im Turbotech II Forschungsvorhaben 1.244 wurden die physikalischen Vorgaenge der rotierenden Instabilitaet untersucht, die sowohl in industriellen Verdichtern als auch in Hochdruckverdichtern von Flugtriebwerken auftreten koennen.

Im Auftrag von Rolls-Royce Deutschland wurden die Untersuchungen von der Faachhochschule Duesseldorf durchgefuehrt. Testobjekt war der neu aufgebaute vier stufige Niedergeschwindigkeitsverdichter der TU Dresden. In enger Kooperation mit den Vorhaben 1.243 und 1.246 wurden umfangreiche Messungen sowohl im rotierenden als auch im festen System an der dritten Stufe des Verdichters durchgefuehrt. Durch Vergroesserung des Spaltes zwischen Schaufelspitze und Verdichterwandung konnten rotierenden Instabilitaeten nachgewiesen werden. Modenanalysen ergaben Umfangsordnungen von ungefaehr 30 bei einer Blattzahl von 63, wodurch die charakteristische Wellenlaenge etwa zwei Schaufelwellenlaengen entspricht. Eine exakte

The detailed method of examination as well as anatomical variants of the vessels are explained. The group of patients was analysed concerning its composition and was subdivided with regard to clinically relevant diagnoses. Contrary to statements in the literature, the number of pathological findings in men or women were equal. The main age was between 40 and 50 years. The brachial vein was found to be doubled so often that this might be accepted as a normal situation. Phlebographic examinations were performed in the right arm twice as often as in the left one. 172 primary examinations, more than 60% showed a pathological result. (orig.)

    Due to finite fossil resources, one opportunity for the future is to increase the supply of energy out of renewable energy sources. One of many opportunities is the use of biomass, which offers plenty combinations of different kinds of biomass, paths of utilization and conversion techniques for a flexible adaptation to natural local and regional frameworks as well as the anthropogenic needs. For an efficient utilization of the limited arable land for the supply of bioenergy, there is a need of up-to-date and proof data about specific energy yields and yields per hectare. The aim of this investigation was to determine these data for the biogas and bioethanol sectors. Batch-tests were carried out in laboratory scaled digesters to investigate specific biogas and bioethanol yields. Additionally the testing of different techniques of pre-treatment for energy crops and their effects on the biogas yield and the progression of the formation of methane were focused. The conversion of maize silage and full ripe triticale into biogas and bioethanol was compared by an energy and environmental balance. The steam explosion technique was included. Pre-treatment The steam explosion pre-treatment of biomass increases the speed of formation of methane and partly increases the methane yields. The effects differ depending on the kind of biomass and the stage of ripening. Other techniques of pre-treatment like microwaving and cooking did not show significant or partly negative effects. A variation of parameters in the trial setup might be interesting. Besides the positive effects of the steam explosion technique there are some arguments like the additional costs of investment, the diminished concentration of nutrients respectively the increase of material flow against it. The additional energy consumption, mostly thermal energy, can be supplied from waste heat out of the combined heat and power plant (CHP). The screening and the production of technical enzymes for the efficient pre

    die verstaerkte Nutzung der z. T. unregelmaessig anfallenden regenerativen Energien sowie von Abwaerme. Der besondere Vorteil der Latentwaermespeicherung besteht in der hohen Energiespeicherdichte, die bei ausgewaehlten Speichermaterialien am Schmelzpunkt erreicht werden kann, und die daraus resultierende Platzeinsparung sowie die nahezu konstante Temperatur. Eine wesentliche Aufgabe bei der Entwicklung solcher Speichersysteme ist die Erhoehung der Langzeitstabilitaet, speziell die Korrosionsstabilitaet ausreichend waermeleitfaehiger Metalle, die als Waermeaustauschermaterial verwendet werden. Das Waermeaustauschermaterial hat dabei die Funktion, die Waerme oder Kaelte von einem Waermeuebertragungsmedium, z. B. Wasser, das die Energie von einer externen Quelle aufgenommen hat, auf das Speichermaterial zu uebertragen. Bei den Speichermaterialien hat sich das Natriumacetetat-Trihydrat mit einem Schmelzpunkt von 58 C als besonders vorteilhaft erwiesen. Eine wichtige Aufgabe war daher die Untersuchung des Korrosionsverhaltens und die Ableitung geeigneter Waermeaustauschermaterialien. Im vorliegenden Beitrag werden wichtige Ergebnisse der Untersuchung ausgewaehlter Metalle bei 80 C in Natriumacetat-Trihydrat-Schmelze vorgestellt. Dem analysenreinen Natriumacetat-Trihydrat wurden ausserdem gezielt die korrosionsbeeinflussenden Verunreinigungen Chlorid, Sulfat und Karbonat, die im wesentlich preisguenstigeren Salzhydrat technischer Qualitaet vorkommen koennen, zugesetzt. Darueber hinaus wurde der Zusatz von Grafit (zur Erhoehung der Waermeleitfaehigkeit) sowie der Zutritt von Luft untersucht. Aus den Untersuchungen wurden mehrere, fuer den genannten Anwendungsfall besonders aussichtsreiche Metalle abgeleitet. (Abstract Copyright [2004], Wiley Periodicals, Inc.)

    strictly. In a semi-technical anammox-reactor which was operated for several years showed, that the process is very robust. Performance loss is only temporary, if the operating conditions aren't fulfilled. (orig.) [German] Bei kommunalen Klaeranlagen mit anaerober Schlammbehandlung faellt bei der Entwaesserung des stabilisierten Schlammes stark ammoniumhaltiges Prozesswasser an. Die Mitbehandlung dieses Teilstroms aus der Schlammbehandlung in der Hauptstrombiologie der Klaeranlage kann zu einer Erhoehung der Stickstoffbelastung von bis zu 20% fuehren. Eine separate Behandlung von Prozesswaessern kann die Stickstoff-Ablaufwerte verbessern und schafft Reserven in der Hauptstrombiologie. Die autotrophe Denitrifikation nach vorangegangener Teilnitritation in Tropfkoerpern ist ein neuartiges Verfahren zur Behandlung hoch ammoniumhaltiger Abwaesser. Hierzu werden in einem ersten Tropfkoerper etwa 60% des Ammoniums zu Nitrit umgewandelt, wobei die Nitratation gehemmt wird. In einem zweiten geschlossenen Tropfkoerper wird das Ammonium unter anoxischen Bedingungen, mit Nitrit als Elektronenakzeptor, zu molekularem Stickstoff oxidiert. Dieses Verfahren wurde erstmals im grosstechnischen Betrieb auf der Klaeranlage Sindelfingen realisiert. Die Untersuchungen zeigten, dass bereits wenige mg/l Ammoniak im ersten Reaktor ausreichten, um die Nitratation zu hemmen. Da die Nitratation nach einem Anstieg und dem darauffolgenden Abfallen der Ammoniakkonzentration zunahm, fand offensichtlich eine Adaption der Biomasse an die hoeheren Ammoniakgehalte statt. Deshalb sollte die Ammoniakkonzentration moeglichst konstant gehalten und groessere Schwankungen ueber eine laengere Zeit vermieden werden. Nur mit der thermischen Abtoetung der Mikroorganismen und dem erneuten Einfahren des Prozesses konnte nach einer Adaption wieder eine vollstaendige Nitratationshemmung bei geringen Ammoniakkonzentrationen gewaehrleistet werden. Durch die aeusserst geringe Wachstumsrate der Anammoxbakterien nimmt

    encountered in clinical imaging for primarily non-senologic questions and therefore differs from what would be expected in a dedicated screening program. The rates of known false-positive BI-RADS 4/5 findings in the retrospective evaluations (1.1 %) and of false-negative findings in the written CT reports (0.2 %) reflect the different diagnostic approaches of image-based senological screening and radiological examinations indicated in order to solve clinical problems not primarily concerning the breast region. Statements regarding the prevalence of clinically occult breast cancers can only be made with caution in the presented, highly selective group of patients due to the often incomplete visualization of breast tissue and the retrospective approach. Key points Intramammary mass and non-mass lesions needing clarification may be present in up to 5.8 % of all contrast enhanced CT-examinations of the female chest. Irregular forms, unscharp/spiculated margins, inhomogeneous matrices and a pronounced contrast medium enhancement point towards a malignant genesis of an intramammary mass or non-mass lesion. The results of the study highlight the importance of paying systematical and targeted attention on senological additional findings in CT-examinations of the chest also in other clinical settings than that of the included patients in a clinic with oncological main focus.

    , auf die abschirmende Wirkung von Septen zwischen den einzelnen Detektorringen (2D-Modus) zu verzichten, so dass auch koinzidente Ereignisse zwischen Detektoren auf weiter entfernt liegenden Ringen erfasst werden koennen (3D-Modus). Ziel der vorliegenden Arbeit war es, das Zaehlratenverhalten eines PET-Scanners der neuesten Generation im 2D- und im 3D-Modus anhand von Phantommessungen zu untersuchen und die sich daraus ergebenden Konsequenzen fuer die Strahlenhygiene bei PET-Untersuchungen mit 2-[F-18]-Fluor-2-Desoxyglukose (F-18-FDG) zu diskutieren. Methoden: Alle Messungen wurden am Ganzkoerper-PET-System ECAT EXACT HR{sup +} durchgefuehrt. Fuer die 2D-Messungen wurde ein Kollimator aus duennen Wolframlamellen in das Gesichtsfeld eingebracht. Das Zaehlratenverhalten des Scanners wurde dem NEMA-Protokoll folgend ueber einen weiten Bereich von F-18-Aktivitaetskonzentrationen untersucht. Darueber hinaus wurden PET-Aufnahmen des EEC-Ganzkoerperphantoms mit verschiedenen Einsaetzen im 2D- und im 3D-Modus jeweils ueber 15 min akquiriert, wobei die F-18-Aktivitaetskonzentrationen bei der 3D-Messung halb so hoch waren wie bei der 2D-Messung. Ergebnisse: Fuer das zylinderfoermige NEMA-Phantom (Durchmesser=19,4 cm, Laenge=19,0 cm) ergab sich im 3D-Modus eine im Vergleich zur 2D-Akquisition etwa fuenffach hoehere Systemsensitivitaet (27,7 statt 5,7 cps/Bq/ml). Die Auswertung der rekonstruierten Aktivitaetsverteilungen des EEC-Phantoms ergab, dass die Qualitaet der aus dem 3D-Projektionsdatensatz berechneten PET-Aufnahmen besser war als die der korrespondierenden 2D-Aufnahmen, obwohl die Aktivitaetskonzentrationen nur halb so hoch waren. Schlussfolgerungen: Durch die Datenakquisition im 3D-Modus kann die zu applizierende Aktivitaetsmenge bei gleichzeitiger Verbesserung der Bildqualitaet erheblich reduziert werden. Fuer Patientenuntersuchungen mit F-18-FDG im Ganzkoerperbereich reicht es unserer Erfahrung nach aus, eine Aktivitaet zwischen 150 und 200 MBq zu applizieren. Dies

    Theoretical and experimental investigations were made in order to find the optimal composition of combustion air for simultaneous reduction of NOx and particulate emissions. The effect was found to be in the same order of magnitude as with exhaust recirculation. 'Optimized' air should have an oxygen content of more than 20 percent and a CO2 content of more than 10 percent, with nitrogen more or less accounting for the rest. [German] Ausgehend von der Abgasrueckfuehrung wurde in theoretischen und experimentellen Untersuchungen die optimale Zusammensetzung der Verbrennungsluft zur gleichzeitigen Reduktion der NO{sub x}- und Partikelemission ermittelt. Es konnte gezeigt werden, dass es mit dieser Verbrennungsluft moeglich ist, eine aehnlich hohe NO{sub x}-Reduktion wie bei der Abgasrueckfuehrung zu erzielen, ohne dass die Partikelemission drastisch ansteigt. Die 'optimale' Verbrennungsluft muss einen Sauerstoffgehalt groesser als 20% und einen CO{sub 2}-Gehalt groesser als 10% aufweisen. Der Rest besteht im Wesentlichen aus Stickstoff. (orig.)

    The Interaction Region Group addressed the basic questions of how to collide the SLC beams, how to maximize and monitor the luminosity, and how to minimize the detector backgrounds at the interaction region. In practice, five subgroups evolved to study these questions. The final focus group provided three alternative designs to acheive the 1 to 2 micron beam spot size required by the SLC, as well as studying other problems including: eta, eta' matching from the collider arcs, the implementation of soft bends near the interaction region, beam emittance growth, and magnet tolerances in the final focus. The beam position monitor group proposed two devices, a strip line monitor, and a beamstrahlung monitor, to bring the beams into collision. The luminosity monitor group reviewed the possible QED processes that would be insensitive to weak interaction (Z 0 ) effects. The beam dumping group proposed locations for kicker and septum magnets in the final focus that would achieve a high dumping efficiency and would meet the desired beam tolerances at the Moller scattering target in the beam dump line. Working with the Polarization Group, the Moller experiment was designed into the beam dump beam line. A beam dump was proposed that would maintain radiation backgrounds (penetrating muons) at acceptible levels. The detector backgrounds group proposed soft-bend and masking configurations to shield the detector from synchrotron radiation from the hard/soft bends and from the final focus quadrupoles and evaluated the effectiveness of these designs for the three final focus optics designs. Backgrounds were also estimated from: large angle synchrotron radiation, local and distant beam-gas interactions, 2-photon interactions, and from neutrons and backscattered photons from the beamstrahlung dump

    The climate sensitivity of the aquatic, amphibic and terrestrial compartments of the lower Weser region was analyzed. This region, located between Bremen and Bremerhaven in northern Germany, is part of a bigger natural reserve ('Unterwesermarsch'). Vegetation and land use were mapped at the biotype level, and forecasts of changes to be expected were attempted on the basis of a regionalised climate scenario. Climate-induced changes in the topology of the headlands and in the morphology of the lower Weser river could not be taken into account.

    Presently axial compressors have to run with considerable distance to operation points of high load although usually the best efficiencies can be obtained there. In those areas there is high danger of surge which brings high damaging potential to the compressor. The prediction time to surge presently is very short (<<1s) and depends on the load and rotor rotation of the compressor. The goal of this project is the production of a data basis to investigate stall inception (which is the precursor of surge) and to develop and test better precursory warning algorithms. An extensive set of data as well in stable as in unstable operating points in different load areas was developed which now is ready for use in research, verification and for comparison of forewarning systems. (orig.) [German] Zur Zeit ist es notwendig, Axialverdichter mit deutlichem Abstand von den hoch belasteten Betriebspunkten zu betreiben, obwohl haeufig dort die besten Wirkungsgrade zu erzielen waeren.

Sie liegen in einem Bereich von deutlich weniger als einer Sekunde (abhaengig von der Belastung und der Drehzahl des Verdichters). Ziel dieser Untersuchungen ist es, eine Datenbasis zu liefern, anhand derer die Entstehungsmechanismen untersucht und moeglichst fruehzeitige Vorwarnalgorithmen entwickelt bzw. erprobt werden koennen. Es wurde eine umfangreiche Datenbasis sowohl an verschiedenen stabilen als auch instabilen Betriebspunkten in unterschiedlichen Lastbereichen erstellt, die nun zur Entwicklung, zur Verifizierung und zum Vergleich von Fruehwarnsystemen zur Verfuegung steht.

    Radiography is often used as an advanced examination to ensure a diagnosis in avian, reptiles and small mammal's medicine. The aims of this thesis were: 1. To measure the radiation exposure of radiological staff caused by radiography of small mammals, reptiles and birds. The exposure of relevant body regions were measured during clinical routine. 2. To examine the differences of radiation exposures caused by radiography of different animal species and to determine the influence of dose-dependent parameters. 3. To present the radiation protection measures of the clinic and to discuss possible improvements. 4. To weigh the anaesthetic risk for small mammals, reptiles and birds against the radiation exposure of the radiological staff. The measurements took place during clinical routine of the Clinic for Exotic Pets, Reptiles, Pet and Feral Birds, University of Veterinary Medicine Hannover, Foundation. The radiation exposure of the radiological staff was measured. The radiological staff included veterinarians, veterinary-medical technical assistants, doctoral candidates and students during their practical year. Furthermore, the radiation exposure was measured at ten representative body regions using thermoluminescence dosimetry. The measuring positions included the eye-lenses, thyroid, thoracic region under the protective clothes, thoracic region above the protective clothes, gonads, fingers and the left foot. Except for one position that was measured under the protective clothes all positions measured above the protective clothes. Moreover at each examination the focus-film-distance, the kV-number, the mAs-product and the weight of the patient was recorded. Additionally the size of the examiner and the examiner's position regarding to the X-ray table were recorded as variable, dose-influencing parameters. Altogether, measurements were taken from 366 individual examiners. In all three divisions 792 X-ray images were made and 3660 dose values recorded. The

    The work reported was to examine whether the modified Gurson model and the Beremin model can be applied to the brittle-ductile transition region of a ferritic steel, and whether the material`s behaviour can be characterized with a failure model integrating the two models mentioned above into one. Any possible improvements of this approach were to be found. The report at first gives a brief list of terminology and formulas used. Chapter 3 explains the microscopic processes typically observed in the transition region in connection with the failure modes of ductile fracture and cleavage fracture, and shows possible approaches for modelling. Chapter 4 defines the specimens and materials, and chapter 5 explains the experiments as well as the microscopic analyses of the fracture surfaces. Chapter 6 presents subsequent calculations representing the processes observed. Based on the stress distributions thus derived, the Beremin model is re-examined for further development. Chapter 7 summarizes the results obtained. (orig./CB) [Deutsch] Ziel der Arbeit ist, zu untersuchen, ob das modifizierte Gurson-Modell und das Beremin-Modell im sproed-duktilen Uebergangsbereich eines ferritischen Stahls einsetzbar sind und ob das Werkstoffverhalten mit einem aus beiden Modellen kombinierten Schaedigungsmodell berechnet werden kann. Gegebenenfalls sind Verbesserungen herbeizufuehren. Die vorliegende Arbeit beginnt mit einer kurzen Einfuehrung der verwendeten Begriffe und Formalismen. In Kap. 3 werden die mikroskopischen Vorgaenge bei den im Uebergangsbereich typischerweise auftretenden Versagensarten duktiler Bruch und Spaltbruch vorgestellt und verschiedene Moeglichkeiten ihrer Modellierung aufgezeigt. Nach der Vorstellung des Probenwerkstoffs werden in Kap. 4 die Experimente beschrieben und die mikroskopischen Untersuchungen der Bruchflaechen in Kap. 5 dargestellt.

    Purpose: to investigate whether diffusion-weighted imaging (DWI) in magnetic resonance imaging (MRI) provides additional information about the periventricular white matter for the assessment of hydrocephalus. Materials and methods: sixteen MRI examinations (11 with acutely increased cerebral pressure, 5 without symptoms) on 15 patients with hydrocephalus (4 patients with communicating hydrocephalus and 11 patients with obstructive hydrocephalus) were analyzed. One symptomatic patient subsequently became asymptomatic. We investigated the ''apparent diffusion coefficient'' (ADC) in the subcortical and periventricular white matter. The ADCs of the study patients were compared with those of a healthy control group. Results: symptomatic patients with hydrocephalus, 6/11 showed periventricular edema and a significantly higher ADC values in the periventricular region than in the subcortical white matter. 5/11 symptomatic patients showed significantly higher ADC values even in the absence of periventricular interstitial edema (both groups contained patients with communicating and obstructive hydrocephalus). All 5 asymptomatic patients with hydrocephalus did not have a significantly higher ADC values in the periventricular region. Conclusion: in patients with hydrocephalus and acutely increased cerebral pressure, DWI showed a significantly higher ADC values in the periventricular region even without visible interstitial edema on conventional MRI sequences.

    The man issues of the studies described were the validation of a test design for the assessment of the bioaccumulation potential of environmental pollutants and the applicability of Eisenia fetida as a model-organism and artificial soil (OECD) as a standard test substrate. The test organisms used were E. fetida of our own breeding stock and Allolobophora caliginosa, Allolobophora chlorotica, Allolobophora longa and Lumbricus rubellus sampled from a field site. Test soils used were the artificial soil (OECD) and a BBA field soil. Soils were each contaminated with 10 mg HCB and Pyrene per soil dry-weight. Within the test period of 4 weeks, samples were taken weekly for residue analysis in the worms and soils. Bioaccumulation factors (AF) calculated for E. fetida and the free-living species were in the range of 10-17 (HCB) and 0.9-1.7 (Pyrene) depending on the soil used. By re-calculation of the concentrations in soil to concentrations in soil water, the resulting bioconcentration factors are compared with published BCF values determined from QSAR's of other worm species and fresh water fish. It could be concluded that the existing earthworm tests (OECD 1984, ISO 1998) represent an appropriate design for testing the bioconcentration potential of chemicals in soil. (orig.)

    Beet molasses, the principal raw material of molasses distilleries and yeast factories, have in recent times with increasing frequency shown negative effects on the fermentation and quality of baking yeast. Based on the fact that with many ``problem molasses`` the inhibitory effect on fermentation can be substantially reduced and often even totally eliminated by prior aeration of the hot acidic molasses solution, the chemical-analytical and biological investigations presented here focused on the components of such problem molasses volatilizable in water vapour. The water vapour distillates contain, in particular, low carbon acids (C1-C10), and alkanols (C6-C7), the minimum inhibitory concentrations (m.i.c.) of which for yeast fermentation were established. This showed very high m.i.c. levels for an inhibitory effect on fermentation, which in practice are not reached by the individual carbon acid and alkanol constituents of the problem molasses. However, these acids and alcohols exhibit marked synergic effects which were confirmed by determining the m.i.c. values of mixtures. The inhibitory effect on yeast fermentation is due above all to the presence in problem molasses of butyric acid + caprilic acid + hexanol and heptanol. (orig.)

    Purpose: In an experimental study, the correlation between the trabecular bone density of the different regions of the proximal femur and the fracture load in the setting of femoral neck fractures was examined. Methods: The bone mineral density 41 random proximal human femora was estimated by single-energy quanitative CT (SE-QCT). The trabecular bone density was measured at the greatest possible extracortical volume at midcapital, midneck and intertrochanteric level and in the 1 cm{sup 3} volumes of the centres of these regions in a standardised 10 mm thick slice in the middle of the femoral neck axis (in mg/ml Ca-hydroxyl apatite). The proximal femora were then isolated and mounted on a compression/bending device under two-legged stand conditions and loaded up to the point when a femoral neck fracture occurred. Results: Statistical analysis revealed a linear correlation between the trabecular bone density and the fracture load for the greater regions, with the highest value in the maximal area of the head (coefficient factor r=0.76). Conclusion: According to our data, the measurement of the trabecular bone by SE-QCT at the femoral head is a more confident adjunct than the neck or trochanteric area to predict a femoral neck fracture.

    Over 250 soil and root samples were collected from forest nurseries and regional research plots as well as from open-air and open-top chambers. The samples were examined for plant parasitic, mycophagous and microphagous nematode and for nematodes able to transmit plant viruses. The results allow conclusions to be drawn concerning nematode population dynamics and the composition of the various trophic groups as related to intensity of forest decline in each station and to some extent to the pH level of the soil.

    Continuous research on climate change has improved the knowledge on climate forecast modelling, so that local and regional climate data sets for the application in building energy modelling are available. The paper analyses the data sets of most known sources and compares the relevant characteristics at four German locations. Simulation results for three commercial building examples (office, school and hotel) illustrate how the climate change may influence heating and cooling demands and capacities as well as the summer thermal comfort if no adjustments with respect to construction, service technology and user behaviour are applied. A significant decrease in space heating demand is contrasted by increased cooling demand and increased indoor temperatures during summer even until 2050. Especially for the office buildings, the summer conditions develop critical, so that active cooling will be mandatory in the summer hot regions. This trend was already detected during the past decade. The forecast is critical for all existing buildings. Significant improvements of the envelope properties such as glazing or shading and passive cooling options become mandatory. The changes predicted for schools and hotels remain moderate.

    Volatile organic compounds (VOC) play an important role in the regional and global atmospheric chemistry. The author of the contribution under consideration reports on the analysis of the ratios of stable carbon isotopes ({delta}({sup 13}C) analysis) in atmospheric VOCs. At first, the state of the art of this analytical technique is described. For the first time {delta}({sup 13}C) values of different monoterpenes have been determined in the investigation of vegetable emissions at a plant chamber. By means of the oxidation of {beta}-pinene by ozone in an aerosol chamber, the kinetic isotope effect of this reaction was determined. In southern Germany, air samples for the {delta}({sup 13}C) analysis were collected using a zeppelin. This enables a height-resolved measurement of {delta}({sup 13}C) values. Based on these measurements, the average photochemical age for methanol, toluene and p-xylene at different heights was calculated.

    Purpose: The aim of the present study was to determine the acute effects of the `Ecstasy` analogue MDE (3,4-methylendioxyethamphetamine) on the cerebral glucose metabolism (rMRGlu) of healthy volunteers. Method: In a randomised double-blind trial, 16 healthy volunteers without a history of drug abuse were examined with 18-FDG PET 110-120 minutes after oral administration of 2 mg/kg MDE (n=8) or placebo (n=8). Beginning two minutes prior to radiotracer injection, a constant cognitive stimulation was maintained for 32 minutes using a word repetition paradigm in order to ensure constant and comparable mental conditions during cerebral 18-FDG uptake. Individual brain anatomy was represented using T1-weighted 3D flash MRI, followed by manual regionalisation into 108 regions-of-interest and PET/MRI overlay. Absolute quantification of rMRGlu and comparison of glucose metabolism under MDE versus placebo were performed using Mann-Whitney U-test. Results: Absolute global MRGlu was not significantly changed under MDE versus placebo (MDE: 41,8{+-}11,1 {mu}mol/min/100 g, placebo: 50,1{+-}18,1 {mu}mol/min/100 g, p=0,298). The normalised regional metabolic data showed a significantly decreased rMRGlu in the bilateral frontal cortex: Left frontal posterior (-7.1%, p<0.05) and right prefrontal superior (-4.6%, p<0.05). On the other hand, rMRGlu was significantly increased in the bilateral cerebellum (right: +10.1%, p<0.05; left: +7.6%, p<0.05) and in the right putamen (+6.2%, p<0.05). Conclusions: The present study revealed acute neurometabolic changes under the `Ecstasy` analogon MDE indicating a fronto-striato-cerebellar dysbalance with parallels to other psychotropic substances and various endogenous psychoses respectively.

    Purpose: To determine typical doses from common CT examinations of standard sized adult patients and their variability between CT operators for common CT indications. Materials and Methods: In a nationwide Austrian CT dose survey doses from approx. 10,000 common CT examinations of adults during 2009 and 2010 were collected and 'typical' radiation doses to the 'average patient', which turned out to have 75.6 kg body mass, calculated. Conversion coefficients from DLP to effective dose were determined and effective doses calculated according to ICRP 103. Variations of typically applied doses to the 'average patient' were expressed as ratios between 90{sup th} and 10{sup th} percentile (inter-percentile width, IPW90/10), 1st and 3{sup rd} quartile (IPW75/25), and Maximum/Minimum. Results: Median effective doses to the average patients for standard head and neck scans were 1.8 mSv (cervical spine), 1.9 mSv (brain: trauma/bleeding, stroke) to 2.2 mSv (brain: masses) with typical variation between facilities of a factor 2.5 (IPW90/10) and 1.7 (IPW75/25). In the thorax region doses were 6.4 to 6.8 mSv (pulmonary embolism, pneumonia and inflammation, oncologic scans), the variation between facilities was by a factor of 2.1 (IPW90/10) and 1.5 (IPW75/25), respectively. In the abdominal region median effective doses from 6.5 mSv (kidney stone search) to 22 mSv (liver lesions) were found (acute abdomen, staging/metastases, lumbar spine: 9-12 mSv; oncologic abdomen plus chest 16 mSv; renal tumor 20 mSv). Variation factors between facilities were on average for abdominal scans 2.7 (IPW90/10) and 1.8 (IPW75/25). Conclusion: Variations between CT operators are generally moderate for most operators, but in some indications the ratio between the minimum and the maximum of average dose to the typical standard patients exceeds a factor of 4 or even 5. Therefore, comparing average doses to Diagnostic Reference Levels (DRLs) and optimizing protocols need to

    Investigating the chemical composition of the atmosphere and its influence on the global climate involves a large number of trace species. Therefore, the Lagrangian transport scheme ATTILA has been developed in this thesis. ATTILA runs online in the general circulation model ECHAM4 and, thus, can be used efficiently for studies involving many tracers. The present study discusses the problems which arise when applying Lagrangian methods on long range and global scale, and describes in detail the solutions developed for ATTILA. Transport experiments with both short-lived and long-lived tracers clearly show that ATTILA is numerically much less diffusive than the operational semi-Lagrangian scheme of ECHAM. It could be shown that the enhanced meridional transport in the tropopause region and the overestimated downward flux through the tropopause in ECHAM are rather due to the numerical properties of the semi-Lagrangian scheme than due to an incorrect circulation. Furthermore, the stratospheric dynamics has been investigated in this study by analysing trajectories and by calculating age spectra and mass fluxes. (orig.)

    The exhaust gas flow in the model thrust nozzle under investigation is characterized by chemical and thermal (vibrational) non-equilibrium which is experimentally detected by differing rotational and vibrational temperatures in the supersonic region of the nozzle. An analytical method to determine the vibrational relaxation time from expansion experiments is presented and validated using literature data. The nitrogen vibrational temperature at the nozzle exit strongly depends on the relaxation time of collisions with water molecules; for this process a correlation from the literature is selected. The measurements are completed by an experimental and numerical analysis of velocimetry tracer particle motion in flows with strong velocity gradients and an experimental investigation of the causes and effects of laser beam distortions occurring in high enthalpy flows. So a reliable database is presented for a reacting flow in a model nozzle of rectangular cross-section which was already used to validate a CFD code including the model of thermal non-equilibrium effects.

    Introduction of PCDD/Fs into the agricultural food chain `atmosphere - fodder - cattle - cows` milk/beef - human` plays a major role in human exposure. The aim of this study was to establish a quantitative relationship between PCDD/Fs immissions and fodder concentrations. The identification of the most important atmospheric pathway of PCDD/F into greenland cultures was conducted under near natural conditions in a combined field/glasshouse experiment. It was found that for the Cl{sub 4-6}DD/Fs dry gaseous and for the Cl{sub 7/8}DD/Fs dry particle-bound deposition was the primary mechanism of uptake. A further greenhouse experiment showed that there is an isomere-unspecific photodegradation of PCDD/Fs on plant surfaces. Dry gaseous deposition, which is the major pathway of atmospheric deposition for the less chlorinated toxicological relevant PCDD/Fs, can be understood as a partitioning process between the gas phase of the atmosphere and the vegetation. Experiments investigating this topic were conducted in the laboratory using PCBs as model substances for the PCDD/Fs. Important knowledge was gained with regard to plant/air partitioning, their dependence on temperature and plant species, the kinetics and reversibility of the process. No partitioning equilibrium between the vegetation and the gas phase of the atmosphere was approached for the PCDD/Fs. The accumulation of PCDD/Fs in agricultural greenland was therefore controlled by a gaseous deposition velocity. In two typical German agricultural regions representative gaseous and particle-bound deposition velocities were determined, which were all in all quite constant and independent of the different exposure conditions. All results from this study were incorporated into a mathematical model of the accumulation of PCDD/Fs and PCBs in greenland. Based on air concentration, plant species composition and growth, temperature and physical-chemical properties of the chemical the model is able to predict the concentration

    In the field of turbo-compressors, the following problems must be solved in order to extend the range of operation: (a) Prevention of rotating stall at part load; (b) Extension of the permissible operating range at part load; (c) Extension of the operation range of radial and side channel compressors in higher vacuum below p{sub s}=50kPa. (c) can be achieved by changing the flow pattern in the rotor and in the region of interaction between the blade wheel and guide wheel of radial compressors or by actively influencing transient flow, e.g. by coupling radial compressor stages with a side channel compressor stage as final stage. The contribution goes into detail about the latter solution. [German] Fuer den Turboverdichterbau sind gegenwaertig folgende Probleme zur Erweiterung der Betriebsbereiche dringend zu loesen: (a) Vermeiden oder beseitigen von Rotating Stall im Teillastbereich,(b) Erweiterung des zulaessigen Arbeitsbereiches im Teillastgebiet, (c) Erschliessung des Arbeitsbereichs von Radial- und Seitenkanalverdichtern im hoeheren Vakuumbereich unterhalb von p{sub s}=50 kPa. Die Erweiterung des zulaessigen Arbeitsbereichs im Teillastgebiet kann durch Veraenderung der Stroemungsstruktur im Laufrad und im Interaktionsbereich zwischen Lauf- und Leitrad von Radialverdichtern oder durch die aktive Beeinflussung der instationaeren Stroemung z.B. durch Kopplung von Radialverdichterstufen mit einer Seitenkanalverdichterstufe als Endstufe erfolgen.

    Full Text Available The development and diversification of the economic activities, the stimulation of investments both in the public sector, but mainly in the private one, the reduction of unemployment, the improvement of living standards are just some of the concepts aimed at by the regional development. The main method which can lead to a balanced development of the regions is financing them differentially so that the underdeveloped regions would obtain proportionally more funds that the developed ones. At a region level, the main objective is represented by the more accelerated growth of the less developed regions, in an effort to diminish the inter-regional and intra-regional development disparities. A key role is played by the sustainable economic growth concept, while also analyzing the competitiveness at a regional level, as well as the main development factors.

    Full Text Available Regional development policy is a policy of investment for economic development by supporting competitiveness, increasing the standards of living, improving the quality of life, creating new jobs. Regions and regional development policy occupies in recent decades an increasingly important position in the list of the economic and social factors being found on the agendas of governments, both central and local authorities, of political groups and civil society. Regional development and regional development policy in Romania are present both in the economic reform and in social one. Development Regions from Romania are set up in 1998 by Law number 151 and supported by their own institutional framework. The applicability of regional development in Romania must take into account the fundamental elements of the possibilities of Regional Development, meaning the major indicators of reference for measuring the level of disparities, GDP per capita and unemployment.

    Introduction of PCDD/Fs into the agricultural food chain `atmosphere - fodder - cattle - cows` milk/beef - human` plays a major role in human exposure. The aim of this study was to establish a quantitative relationship between PCDD/Fs immissions and fodder concentrations. The identification of the most important atmospheric pathway of PCDD/F into greenland cultures was conducted under near natural conditions in a combined field/glasshouse experiment. It was found that for the Cl{sub 4-6}DD/Fs dry gaseous and for the Cl{sub 7/8}DD/Fs dry particle-bound deposition was the primary mechanism of uptake. A further greenhouse experiment showed that there is an isomere-unspecific photodegradation of PCDD/Fs on plant surfaces. Dry gaseous deposition, which is the major pathway of atmospheric deposition for the less chlorinated toxicological relevant PCDD/Fs, can be understood as a partitioning process between the gas phase of the atmosphere and the vegetation. Experiments investigating this topic were conducted in the laboratory using PCBs as model substances for the PCDD/Fs. Important knowledge was gained with regard to plant/air partitioning, their dependence on temperature and plant species, the kinetics and reversibility of the process. No partitioning equilibrium between the vegetation and the gas phase of the atmosphere was approached for the PCDD/Fs. The accumulation of PCDD/Fs in agricultural greenland was therefore controlled by a gaseous deposition velocity. In two typical German agricultural regions representative gaseous and particle-bound deposition velocities were determined, which were all in all quite constant and independent of the different exposure conditions. All results from this study were incorporated into a mathematical model of the accumulation of PCDD/Fs and PCBs in greenland. Based on air concentration, plant species composition and growth, temperature and physical-chemical properties of the chemical the model is able to predict the concentration

    In the course of this work extensive equilibrium studies were carried out in the four-system systems Li / M / P / O (M: Cr, Mn) in the search for new, powerful cathode materials for lithium ion batteries. The phosphates LiCr{sup II}{sub 4}(PO{sub 4}){sub 3}, NaCr{sup II}{sub 4}(PO{sub 4}){sub 3}, Li{sub 5}Cr{sup II}{sub 2}Cr{sup III}(PO{sub 4}){sub 4}, monoclines Li{sub 3}Cr{sub 2}(PO{sub 4}){sub 3}, Cr{sup II}{sub 5}Cr{sup III}{sub 2}(P{sub 2}O{sub 7}){sub 4} and LiMn{sup II}{sub 2}P{sub 3}O{sub 10} were obtained for the first time. The present work reports on their synthesis, crystallographic characterization and their spectroscopic and magnetic properties. The equilibrium studies in the Li / Cr / P / O system led to the elucidation of numerous phase relationships. For example, the coexistence regions LiCr{sub 4}(PO{sub 4}){sub 3} / Li{sub 5}Cr{sub 3}(PO{sub 4}){sub 4} / Cr{sub 2}O{sub 3} / CrP and Li{sub 9}Cr{sub 3}(PO{sub 4}){sub 3} / LiCrP{sub 2}O{sub 7} / CrP. The coexistence of some equilibrium phases such as lithium orthophosphate and lithium manganese(II) orthophosphate as well as lithium metaphosphate and manganese(III) metaphosphate were also investigated in the Li / Mn / P / O system. Furthermore, the de-intercalation behavior of silver manganese phosphates was investigated with the possibility of demonstrating metastable phosphates with manganese in oxidation states higher than 3+. In this case the four-substance system Ag / Mn / P / O with Mn(II) and Mn(III) was considered. The reaction conditions were adapted to those of the experiments in the corresponding lithium-containing systems. Within the scope of the equilibrium studies two new pyrophosphates AgMnP{sub 2}O{sub 7} and Ag{sub 1,6}Mn{sub 3}(P{sub 2}O{sub 7}){sub 2} were found and characterized.

    This paper deals with a precise description of the region of zitterbewegung below the Compton scale and the stochastic nature associated with it. We endeavor to delineate this particular region by means of Ito’s calculus and instigate certain features that are in sharp contrast with conventional physics. Interestingly, our work substantiates that the zitterbewegung region represents a pre-space-time region and from therein emerges the notion of our conventional space-time. Interestingly, this unique region engenders the relativistic and quantum mechanical aspects of space-time.

    In this project a chemical mechanism was developed for the upper troposphere which permits examining the photochemical formation of ozone. Using this mechanism it was found that at medium latitudes (at 10 km altitude in June) hydroxyl radical concentration and the rate of photochemical ozone formation to which it is coupled depend on NO{sub x} concentrations in a strongly non-linear manner, peaking at 110 ppt NO{sub x} and 200 pp NO{sub x}, respectively. Regarding the assessment of the effects of air traffic it was thus shown that in attempting to forecast changes in ozone concentration one must not only take aviation-related changes in NO{sub x} concentrations into account but also the forecasted absolute concentrations of NO{sub x}. The measured data were interpreted by combining a simplified model of NO{sub x} reactions with an existing three-dimensional transport model and comparing the measured and the calculated vertical NO profiles. It can be said that the 3D chemical transport model supplies realistic tropospheric NO{sub x} ratios at least for medium latitudes (49 to 56 N) in the months of May, June, July, December, and January. At these latitudes the tropospheric NO{sub x} budget is mainly governed by anthropogenic emissions. (orig./KW) [Deutsch] In diesem Projekt wurde ein Chemiemechanismus fuer die obere Troposphaere entwickelt, der es erlaubt, die photochemische Ozonbildung zu untersuchen. Mit diesem Mechanismus konnte fuer mittlere noerdliche Breiten (fuer 10 km Hoehe, Juni) gezeigt werden, dass die Hydroxylradikalkonzentration und die damit gekoppelte photochemische Ozonbildungsrate in stark nichtlinearer Weise von der Stickoxidkonzentration abhaengen und bei etwa 110 ppt NO{sub x} (bezw. 200 ppt NO{sub x} fuer die Ozonbildungsrate) ein Maximum durchlaufen. Fuer die Beurteilung der Auswirkungen des Flugverkehrs konnte deswegen gezeigt werden, dass die Voraussagen ueber Ozonveraenderungen nicht nur von der Aenderung der Stickoxidkonzentration durch den Flugverkehr abhaengen, sondern auch von den vorhergesagten Absolutkonzentrationen der Stickoxide. Fuer die Interpretation der Messdaten wurde ein vorhandenes 3 dimensionales Transportmodell mit einer einfachen Chemie der Stickoxide versehen und die gemessenen Vertikalprofile von NO mit berechneten verglichen. Es kann gesagt werden, dass das 3D-chemische Transportmodell realistische Stickoxidmischungsverhaeltnisse in der Troposphaere in mittleren Breiten (49 N bis 56 N) in den Monaten Mai, Juni und Juli sowie November, Dezember und Januar liefert. In diesen Breiten wird das troposphaerische Budget der Stickoxide hauptsaechlich durch anthropogene Emissionen bestimmt. (orig./KW)

    The sperm cells of Patella coerulea (Patellacea), Monodonta turbinata, and Gibbula tumida (Trochacea) were investigated by means of transmission electron microscopy. They belong to the primitive type (sensu Franzén) and have more features in common with primitive Bivalvia sperms than with Neritacea. Their head contains an apical acrosome and a roundish nucleus followed by 4 or 5 mitochondria and a centriolar apparatus which consists of two centrioles, one of which bears a flagellum. The sperm cells of Monodonta and Gibbula are very similar to each other and differ mainly in size; Patella exhibits more differences (very small acrosome, subacrosomal space, variable number of spherical mitochondria (origin of spermic dimorphism ?). The development of the sperm cells shows no peculiarities.

    Typical dry products such as gums, drugs and spices were irradiated with 10 MeV electrons up to doses of 30 kGy. Such treatments led in the majority of cases to an undesirable change in the reological properties of gums. The ingredients of drugs, especially essential volatiles, remained unchanged. In individual cases, however, a dose of 10 kGy was not sufficient to reduce total microbial counts. Changes in the sensory properties were not observed, but with the previous tested spices pronounced changes in sensory properties were not observed, but pronounced changes in colour at doses of 10 kGy were observed. These changes did not affect the quality, however. Changes in taste and odour were not recognizable. To reduce microbial counts as desired, a dose of 10 kGy was sufficient.

    The composite containment design for advanced LWRs that has been examined under the PASCO project is a promising design concept for purely passive decay heat removal after a severe accident. The passive cooling processes applied are natural convection and radiative heat transfer. Heat transfer through the latter process removes at an emission coefficient of 0.9 about 50% of the total heat removed via the steel containment, and thus is an essential factor. The heat transferring surfaces must have a high emission coefficient. The sump cooling concept examined under the SUCO project achieves a steady, natural convection-driven flow from the heat source to the heat sink. (orig./CB) [Deutsch] Das im PASCO Programm untersuchte Verbundcontainment fuer zukuenftige Leichtwasserreaktoren ist ein erfolgversprechendes rein passives System zur Nachwaermeabfuhr nach einem schweren Stoerfall. Die passiven Mechanismen der Waermeuebertragung sind Naturkonvektion und Waermestrahlung. Die durch Waermestrahlung uebertragene Waerme betraegt fuer einen Emissionskoeffizienten von 0.9 etwa 50% der insgesamt ueber das Stahl-Containment abgefuehrten Waerme und ist somit von entscheidender Bedeutung fuer die Nachwaermeabfuhr. Fuer die waermeuebertragenden Oberflaechen ist ein hoher Emissionkoeffizient erforderlich.

The basic tasks of tourism development in the region, aimed at the formation and protection of the tourism-recreational sector, market of competitive services, attraction of maximum number of tourists to the region, etc. have been cleared out. The attention is focused on the main tourist potential of Khmelnytskyi region, including National Nature Park «Podilski Tovtry», National historical-cultural nature reserve «Kamianets», «Samchyky», Medzhybizh regional historical-ethnographic museum-fortress, sanatorium-resort facilities based on mineral waters and others. The attention is paid to the increase in income from tourism. Traditional hospitality of the population of the region, especially in rural areas, provides the possibility to combine tourists’ accommodation with the study of rural customs and traditions directly in the villages. Tourism in Khmelnytskyi region will be attractive to all tourists who want to eat healthy food, to stay outdoors and enjoy the beauty of the region. Also the article tells us about the development of other directions and familiarizes tourists with other enticements of Khmelnytskyi region using the positive brand of Kamianets-Podilskyi. All three potential areas of tourism development (historical tourism in Kamianets-Podilskyi, recreational tourism on rivers, lakes and in the forests, as well as rural tourism can be combined within the global promotion of nature and traditions of the region. It is indicated that Khmelnytskyi is a promising tourist region of Ukraine. The main problems of the region are inadequate tourism infrastructure, accommodation facilities, food and roads. The experience of the tourism cluster «Oberih» (Protective Charm proves the perspectives of agritourism. Developing these two areas together, we

    A probable evolutionary sequence of H II regions based on six distinct types of observed objects is suggested. Two examples which may deviate from this idealized sequence, are discussed. Even though a size-mean density relation of H II regions can be used as a rough indication of whether a nebula is very young or evolved, it is argued that such a relation is not likely to be useful for the quantitative assignment of ages to H II regions. Evolved H II regions appear to fit into one of four structural types: rings, core-halos, smooth structures, and irregular or filamentary structures. Examples of each type are given with their derived physical parameters. The energy balance in these nebulae is considered. The mass of ionized gas in evolved H II regions is in general too large to trace the nebula back to single compact H II regions. Finally, the morphological type of the Galaxy is considered from its H II region content. 2 tables, 2 figs., 29 refs

  11. Regional Ocean Data Assimilation

    KAUST Repository

    Edwards, Christopher A.

    2015-01-03

    This article reviews the past 15 years of developments in regional ocean data assimilation. A variety of scientific, management, and safety-related objectives motivate marine scientists to characterize many ocean environments, including coastal regions. As in weather prediction, the accurate representation of physical, chemical, and/or biological properties in the ocean is challenging. Models and observations alone provide imperfect representations of the ocean state, but together they can offer improved estimates. Variational and sequential methods are among the most widely used in regional ocean systems, and there have been exciting recent advances in ensemble and four-dimensional variational approaches. These techniques are increasingly being tested and adapted for biogeochemical applications.

    2000-07-01

    Although for some years now, 'clustering' as a new approach in business and industry sectors has become known as a keyword for new trajectories of great promise for economic growth and enhanced technological innovation, there is only insufficient information dealing with the rationale, or the major structures and development dynamics of such networking strategies. The authors therefore have carried out a systematic study presented in this book. Regional interlinking structures between enterprises are examined and explained as organisational, corporate networks and their capabilities, including a historical profile and analysis. Questions marking starting points of the study are: How do functional and geographical clusters evolve? How do they change over the life cycle of products and industries (pathway dependence)? What interactions are there between the geographical context (locations and regions) and the system of interlacements between industry and the scientific community? The rail vehicle industry is chosen as a system technolgy example illustrating the clustering process, and a detailed empirical analysis is given of the region of Berlin-Brandenburg. The study shows the constraints of existing theoretical approaches in explaining the evolution of regional clusters in business and industry sectors, and indicates new pathways for theoretical studies.

    International Nuclear Information System (INIS)

    Greene, J.M.; Chance, M.S.

    1980-10-01

    A new type of axisymmetric magnetohydrodynamic equilibrium is presented. It is characterized by a region of pressure and safety factor variation with a short scale length imposed as a perturbation. The equilibrium consistent with these profile variations can be calculated by means of an asymptotic expansion. The flexibility obtained by generating such equilibria allows for a close examination of the mechanisms that are relevant to ballooning instabilities - ideal MHD modes with large toroidal mode number. The so-called first and second regions of stability against these modes are seen well within the limits of validity of the asymptotic expansion. It appears that the modes must be localized in regions with small values of the local shear of the magnetic field. The second region of stability occurs where the local shear is large throughout the range where the magnetic field line curvature is destabilizing

    Pricing of transport has been part of EU's common transport policy since this gained momentum in the early 1990s. Since then, it has been closely connected to the trans-European transport network (TEN-T) and to rising demands of efficient mobility systems at a local, regional and Community scale....... Development of pricing policies is contested at Community level and has taken place in a clash between different policy rationalities. Significantly though, the effects of the pricing policies are closely related to regional mobility systems, e.g. through financing large trans-border infrastructure projects...... and establishing common technical charging systems thus changing the conditions for regional mobility. This paper explores how policies of infrastructure pricing shape new ways of governing mobility which influences trans-border, regional policy-making.

    The Regional Cooperation Agreement (RCA) for Research Development and Training Related to Nuclear Science and Technology, formulated under the auspices of the International Atomic Energy Agency (IAEA), came into force in June 1972. The overall objective of RCA is to promote technical cooperation among the developing and developed countries in the Asia Pacific region in the peaceful uses of nuclear energy and related technology. Currently, the biggest project under RCA is the Regional Project on the Industrial Applications of Isotopes and Radiation Technology for Asia and the Pacific. The project was established in 1982 for a period of five years and was completed in December 1986. The first phase of the project has generated a high degree of awareness on the industrial potential of isotopes and radiation technology throughout the region; produced a cadre of trained manpower in all areas covered by the project; identified the expertise available in the region; and developed in the region, a unique network of people and institutions involved with the utilization of isotope and radiation technology. A Phase II of the project, which cover all but one of the sub-projects under Phase I, was approved in early 1987 for another five years until 1991. (Nogami, K.)

    The NRC Office of Inspection and Enforcement (IE) has elected to evaluate the effectiveness and efficiency of its existing regional boundary alignment because of the anticipated future growth of nuclear power generating facilities and corresponding inspection requirements. This report documents a management study designed to identify, analyze, and evaluate alternative regional boundary configurations for the NRC/IE regions. Eight boundary configurations were chosen for evaluation. These configurations offered alternatives ranging from two to ten regions, and some included the concepts of subregional or satellite offices. Each alternative configuration was evaluated according to three major criteria: project workload, cost, and office location. Each major criterion included elements such as management control, program uniformity, disruption, costs, and coordination with other agencies. The conclusion reached was that regional configurations with regions of equal and relatively large workloads, combined with the concepts of subregional or satellite offices, may offer a significant benefit to the Office of Inspection and Enforcement and the Commission and are worthy of further study. A phased implementation plan, which is suitable to some configurations, may help mitigate the disruption created by realignment

    In this study, a regional analysis of the Argentine electricity market was carried out considering the effects of regional cooperation, national and international interconnections; additionally, the possibilities of insertion of new nuclear power plants in different regions were evaluated, indicating the most suitable areas for these facilities to increase the penetration of nuclear energy in national energy matrix. The interconnection of electricity markets and natural gas due to the linkage between both energy forms was also studied. With this purpose, MESSAGE program was used (Model for Energy Supply Strategy Alternatives and their General Environmental Impacts), promoted by the International Atomic Energy Agency (IAEA). This model performs a country-level economic optimization, resulting in the minimum cost for the modelling system. Regionalization executed by the Wholesale Electricity Market Management Company (CAMMESA, by its Spanish acronym) that divides the country into eight regions. The characteristics and the needs of each region, their respective demands and supplies of electricity and natural gas, as well as existing and planned interconnections, consisting of power lines and pipelines were taken into account. According to the results obtained through the model, nuclear is a competitive option. (author) [es

    North America is an energy community fortunate to be endowed with a rich and varied resource base. It consumes about a third of the world's energy and produces about one quarter of world energy supply. North America depends on a mix of complementary energy sources that should remain competitive but not in conflict. The current supply mix varies between Canada, the United States and Mexico, but fossil fuels are dominant across the region, leaving the three member countries vulnerable to a myriad of risks associated with traditional supply sources. Energy trade between all three countries is also a major contributor to the region's economy. Thus, the impetus for collaboration across the region has grown out of the common goals of energy security and economic prosperity. The goal of the WEC regional group was to discuss avenues for advancing North American cooperation and coordination on a range of energy issues. An additional objective was to develop policy recommendations that will facilitate effective development and use of the region's energy resources. Results and recommendtaions are summarized from three forums that focused on the pertinent issues of energy trade, energy efficiency and energy diversification. The inaugural forum (Energy Trade) was held in Washington, D.C. in the fall of 2005. The following summer, the second forum (Energy Efficiency) took place in Mexico City.

    2011-09-01

    Full Text Available Transient osteoporosis of the hip and regional migratory osteoporosis are uncommon and probably underdiagnosed bone diseases characterized by pain and functional limitation mainly affecting weight-bearing joints of the lower limbs. These conditions are usually self-limiting and symptoms tend to abate within a few months without sequelae. Routine laboratory investigations are unremarkable. Middle aged men and women during the last months of pregnancy or in the immediate post-partum period are principally affected. Osteopenia with preservation of articular space and transitory edema of the bone marrow provided by magnetic resonance imaging are common to these two conditions, so they are also known by the term regional transitory osteoporosis. The appearance of bone marrow edema is not specific to regional transitory osteoporosis but can be observed in several diseases, i.e. trauma, reflex sympathetic dystrophy, avascular osteonecrosis, infections, tumors from which it must be differentiated. The etiology of this condition is unknown. Pathogenesis is still debated in particular the relationship with reflex sympathetic dystrophy, with which regional transitory osteoporosis is often identified. The purpose of the present review is to remark on the relationship between transient osteoporosis of the hip and regional migratory osteoporosis with particular attention to the bone marrow edema pattern and relative differential diagnosis.

  20. Regional Resource Planning Study

    International Nuclear Information System (INIS)

    2001-01-01

    Natural gas and electricity commodities are among the most volatile commodities in the world. Spurred on by the recent significant increases in the price of natural gas, the BC Utilities Commission initiated an investigation into factors impacting on natural gas prices, and the validity of the Sumas index (a market trading point, or interchange where multiple pipelines interconnect, allowing the purchase and sale of gas among market participants) as a price setting mechanism. The Commission also sought the opinions and perspectives of the the province's natural gas industry regarding the high volatility of the Sumas gas prices, and as to what could be done to alleviate the wild fluctuations. Following review of the responses from stakeholders, the Commission issued a directive to BC Gas to undertake discussions on regional resource planning with full representation from all stakeholders. This study is the result of the Commission's directive, and is intended to address the issues contained in the directives. Accordingly, the study examined gas demand in the region, demand growth, including power generation, natural gas resource balance in the region, the California impacts on demand and on supply to the region, supply shortfalls on a peak day, and on a seasonal and annual basis, near term remedies, possible resource additions in the longer term, the economic justification for adding major resources and proposed actions to develop needed resource additions. The study confirmed the existence of a growing capacity deficit, which limits the supply of natural gas to the region. Near term options to alleviate the regional capacity deficit were found to be limited to discouraging power generation from serving export markets, demand side management efforts, and expansion of the WEI's systems by 105 mmcf/d. Longer term solutions would involve larger scale expansion of WEI's T-South capacity, the BC Gas' Inland Pacific Connector Project and the Washington Lateral proposed by

    This Magellan radar image is of part of the Phoebe region of Venus. It is a mosaic of parts of revolutions 146 and 147 acquired in the first radar test on Aug. 16, 1990. The area in the image is located at 291 degrees east longitude, 19 degrees south latitude. The image shows an area 30 kilometers (19.6 miles) wide and 76 km (47 miles) long. On the basis of Pioneer Venus and Arecibo data, it is known that two major rift zones occur in southern Phoebe Regio and that they terminate at about 20 to 25 degrees south latitude, about 2,000 km (1,240 miles) apart. This image is of an area just north of the southern end of the western rift zone. The region is characterized by a complex geologic history involving both volcanism and faulting. Several of the geologic units show distinctive overlapping or cross cutting relationships that permit identification and separation of geologic events and construction of the geologic history of the region. The oldest rocks in this image form the complexly deformed and faulted, radar bright, hilly terrain in the northern half. Faults of a variety of orientations are observed. A narrow fault trough (about one-half to one km (three tenths to six tenths of a mile) wide is seen crossing the bright hills near the lower part in the middle of the image. This is one of the youngest faults in the faulted, hilly unit as it is seen to cut across many other structures. The fault trough in turn appears to be embayed and flooded by the darker plains that appear in the south half of the image. These plains are interpreted to be of volcanic origin. The dark plains may be formed of a complex of overlapping volcanic flows. For example, the somewhat darker region of plains in the lower left (southwest) corner of the image may be a different age series of plains forming volcanic lava flows. Finally, the narrow bright line crossing the image in its lower part is interpreted to be a fault which cross cuts both plains units and is thus the youngest event in

    In response to the Low-Level Radioactive Waste Policy Act of 1980, the States of Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio and Wisconsin formed the Midwest Interstate Low-Level Radioactive Waste Compact. One of the top priorities of the Compact Commission is the development of a comprehensive regional waste management plan. The plan consists of five major elements: (1) waste inventory; (2) waste stream projections; (3) analysis of waste management and disposal options; (4) development of a regional waste management system; and (5) selection of a host state(s) for future low-level waste facilities. When completed, the Midwest Management Plan will serve as the framework for future low-level radioactive waste management and disposal decisions

The overflowing waters of the region's rivers damaged 3000 residential buildings, completely destroyed another 426, and seriously affected the activities of 850 business establishments. In this comprehensive report, the physical causes and the social, economic, psychological, cultural, political and administrative consequences of this natural catastrophe are discussed by several experts. The report is divided into three parts. The first part describes the actual flooding conditions and the immediate response of local emergency services such as the Red Cross and the Saint-Vincent-de-Paul agencies. Reactions of the various public agencies and governments to the disaster are described in Part Two. Part Three of the document focuses on lessons to be drawn from this natural disaster, in particular the need to improve emergency relief strategies.

    Full Text Available From the 1980s onwards the banking sectors in all the industrialised countries have been experiencing intense restructuring, aggregation and consolidation, radically changing their ownership structures and geography. Whatever the reasons behind such restructuring processes, the globalisation of the credit markets, the consolidation of banking structures, the removal of barriers to the free location of banks and their penetration of peripheral markets pose two main questions. Will integration of the banking systems lead to a narrowing or a widening of the development gap between regions? What relations will there be between financial centres and the periphery, and how will financial labour be divided between national (international banks and local (regional banks? The aim of this paper is to address such questions in the light of recent developments in the theoretical and empirical literature on financial integration.

    We are building a multidisciplinary research program linking researchers in agriculture, business, earth science, engineering, humanities and social science. Our goal is to match renewable energy supply and reformed energy demands. The program will be focused on (i) understanding and modifying energy demand, (ii) design and implementation of diverse renewable energy networks. Geomatics technology will be used to map existing energy and waste flows on a neighbourhood, municipal, and regional level. Optimal sites and combinations of sites for solar and wind electrical generation (ridges, rooftops, valley walls) will be identified. Geomatics based site and grid analyses will identify best locations for energy production based on efficient production and connectivity to regional grids and transportation. Design of networks for utilization of waste streams of heat, water, animal and human waste for energy production will be investigated. Agriculture, cities and industry produce many waste streams that are not well utilized. Therefore, establishing a renewable energy resource mapping and planning program for electrical generation, waste heat and energy recovery, biomass collection, and biochar, biodiesel and syngas production is critical to regional energy optimization. Electrical storage and demand management are two priorities that will be investigated. Regional scale cooperatives may use electric vehicle batteries and innovations such as pump storage and concentrated solar molten salt heat storage for steam turbine electrical generation. Energy demand management is poorly explored in Canada and elsewhere - our homes and businesses operate on an unrestricted demand. Simple monitoring and energy demand-ranking software can easily reduce peaks demands and move lower ranked uses to non-peak periods, thereby reducing the grid size needed to meet peak demands. Peak demand strains the current energy grid capacity and often requires demand balancing projects and

    The authors discuss the impact of an increasing greenhouse effect on three aspects of regional climate: droughts, storms and temperature. A continuous of current growth rates of greenhouse gases causes an increase in the frequency and severity of droughts in their climate model simulations, with the greatest impacts in broad regions of the subtropics and middle latitudes. But the greenhouse effect enhances both ends of the hydrologic cycle in the model, that is, there is an increased frequency of extreme wet situations, as well as increased drought. Model results are shown to imply that increased greenhouse warming will lead to more intense thunderstorms, that is, deeper thunderstorms with greater rainfall. Emanual has shown that the model results also imply that the greenhouse warming leads to more destructive tropical cyclones. The authors present updated records of observed temperatures and show that the observations and model results, averaged over the globe and over the US, are generally consistent. The impacts of simulated climate changes on droughts, storms and temperature provide no evidence that there will be regional winners if greenhouse gases continue to increase rapidly

    Full Text Available The purpose of this contribution is to discuss what roles the different economic sectors, and in particular services activities (the tertiary sector play in regional development, understood as growth in production, incomes and employment in weakly developedregions. This question is approached in two ways. The contribution first contains a – primarily theoretical – re-examination of the so-called economic base model, which states that services play a passive role in regional development. The discussion leads to substantial modifications of the model. The second approach is more empirical. It will take as its point of departure the proposition – often heard, but rarely examined – that since service activities are more concentrated in big cities than other activities and in recent decades have shown higher growth rates than other economic activities, it follows that the economic development is now pulled towards big city regions. Examined by way of a statistical analysisin Denmark and France, this proposition could not be verified.

    International Nuclear Information System (INIS)

    1992-01-01

    An introduction to the Alligator Rivers Region is presented. It contains general information regarding the physiography, climate, hydrology and mining of the region. The Alligator Rivers Region is within an ancient basin, the Pine Creek Geosyncline, which has an area of approximately 66000 km 2 . The Geosyncline has a history of mineral exploitation dating back to 1865, during which time 16 metals have been extracted (silver, arsenic, gold, bismuth, cadmium, cobalt, copper, iron, manganese, molybdenum, lead, tin, tantalum, uranium, tungsten, zinc). Uranium exploration in the Pine Creek Geosyncline was stimulated by the discovery in 1949 of secondary uranium mineralisation near Rum June, 70 km south-east of Darwin. This was followed by a decade of intense exploration activity resulting in the discoveries of economic uranium ore bodies at Rum Jungle and in the upper reaches of the South Alligator River Valley. All the known major uranium deposits of the East Alligator River uranium field have been discovered since 1969. The present known resources of the Geosyncline are approximately 360 000 tonnes of contained U 3 O 8 . 2 refs., 2 figs., 1 tab

    1999-10-01

    New opportunities for climate change mitigation arising from a higher energy integration among Andean Pact nations were analysed within the framework of the UNEP/GEF Project. Apart from the search for regional mitigation actions, the study was mainly aimed at detecting methodological problems which arise when passing from a strictly national view to the co-ordination of regional actions to deal with climate change. In accordance with the available resources and data, and in view of the mainly methodological nature of the project, it was decided to analyse the opportunities to delve into the energy integration of the Region as regards electricity and natural gas industries and their eventual impact on the emission of greenhouse gases. Although possibilities of setting up electricity and natural gas markets are real, their impacts on GHG emission from the energy system would not prove substantially higher than those which the nations could achieve through the use of their own energy resources, in view that the Andean systems are competitive rather than complementary. More in-depth studies and detail information will be required - unavailable for the present study - to be able to properly evaluate all benefits associated with higher energy integration. Nevertheless, the supply of natural gas to Ecuador seems to be the alternative with the highest impact on GHG emission. If we were to analyse the supply and final consumption of energy jointly, we would most certainly detect additional mitigation options resulting from higher co-operation and co-ordination in the energy field.

    The fallout from a nuclear explosion has the potential to injure or kill 100,000 or more people through exposure to external gamma (fallout) radiation. Existing buildings can reduce radiation exposure by placing material between fallout particles and exposed people. Lawrence Livermore National Laboratory was tasked with developing an operationally feasible methodology that could improve fallout casualty estimates. The methodology, called a Regional Shelter Analysis, combines the fallout protection that existing buildings provide civilian populations with the distribution of people in various locations. The Regional Shelter Analysis method allows the consideration of (a) multiple building types and locations within buildings, (b) country specific estimates, (c) population posture (e.g., unwarned vs. minimally warned), and (d) the time of day (e.g., night vs. day). The protection estimates can be combined with fallout predictions (or measurements) to (a) provide a more accurate assessment of exposure and injury and (b) evaluate the effectiveness of various casualty mitigation strategies. This report describes the Regional Shelter Analysis methodology, highlights key operational aspects (including demonstrating that the methodology is compatible with current tools), illustrates how to implement the methodology, and provides suggestions for future work.

    Observational aspects of the transition region and coronal structures of the solar active region are reviewed with an emphasis on imaging of the plasma loops which act as tracers of the magnetic flux loops. The study of the basic structure of an active region is discussed in terms of the morphological and thermal classifications of active region loops, including umbral structures, and observational knowledge of the thermal structure of loops is considered in relation to scaling laws, emission measures and the structures of individual loops. The temporal evolution of active region loop structures is reviewed with emphasis on ephemeral regions and the emergence of active regions. Planned future spaceborne observations of active region loop structures in the EUV and soft X-ray regions are also indicated

    Because studies of the regional impact of climate change need higher spatial resolution than that obtained in standard global climate change scenarios, developing regional scenarios from models is a crucial goal for the climate modelling community. The zoom capacity of ARPEGE-Climat, the Meteo-France climate model, allows use of scenarios with a horizontal resolution of about 50 km over France and the Mediterranean basin. An IPCC-A2 scenario for the end of the 21. century in France shows higher temperatures in each season and more winter and less summer precipitation than now. Tuning the modelled statistical distributions to observed temperature and precipitation allows us to study changes in the frequency of extreme events between today's climate and that at the end of century. The frequency of very hot days in summer will increase. In particular, the frequency of days with a maximum temperature above 35 deg C will be multiplied by a factor of 10, on average. In our scenario, the Toulouse area and Provence might see one quarter of their summer days with a maximum temperature above 35 deg C. (author)

    Transient regional osteoporosis (TRO) is a disease that predisposes to fragility fracture in weight bearing joints of mid-life women and men. Pregnant women may also suffer the process, usually at the hip. The prevalence of TRO is lower than the systemic form, associated with postmenopause and advanced age, but may be falsely diminished by under-diagnosis. The disease may be uni- or bilateral, and may migrate to distinct joints. One main feature of TRO is spontaneous recovery. Pain and progressive limitation in the functionality of the affected joint(s) are key symptoms. In the case of the form associated with pregnancy, difficulties in diagnosis derive from the relatively young age at presentation and from the clinical overlapping with the frequent aches during gestation. Densitometric osteoporosis in the affected region is not always present, but bone marrow edema, with or without joint effusion, is detected by magnetic resonance. There are not treatment guidelines, but the association of antiresorptives to symptomatic treatment seems to be beneficial. Surgery or other orthopedic interventions can be required for specific indications, like hip fracture, intra-medullary decompression, or other. Copyright © 2014 Elsevier Ireland Ltd.

    Full Text Available An evaluation of healthcare systems effectiveness of the regions of the Russian Federation (federal districts was conducted using the Minmax method based on the data available at the United Interdepartmental Statistical Information System. Four groups of components (i.e. availability of resources; use of resources; access to resources and medical effectiveness decomposed into 17 items were analyzed. The resource availability was measured by four indicators, including the provision of doctors, nurses, hospital beds; agencies providing health care to the population. Use of resources was measured by seven indicators: the average hospital stay, days; the average bed occupancy, days; the number of operations per 1 physician surgical; the cost per unit volume of medical care: in outpatient clinics, day hospitals, inpatient and emergency care. Access to the resources was measured by three indicators: the satisfaction of the population by medical care; the capacity of outpatient clinics; the average number of visits to health facility. The medical effectiveness was also measured by three indicators: incidence with the "first-ever diagnosis of malignancy"; life expectancy at birth, years; the number of days of temporary disability. The study of the dynamics of the components and indexes for 2008–2012 allows to indicate a multidirectional influence on the regional healthcare system. In some federal districts (e.g. North Caucasian, the effectiveness decreases due to resource availability, in others (South, North Caucasian — due to the use of resources, in others (Far Eastern, Ural — due to access to resources. It is found that the effectiveness of the healthcare systems of the federal districts differs significantly. In addition, the built matrix proves the variability the of effectiveness (comparison of expenditures and results of healthcare systems of the federal districts of the Russian Federation: the high results can be obtained at high costs

    Nuclear cooperation between Argentina and Brazil has been growing since the early 1980's and as it grew, so did cooperation with the US Department of Energy (DOE). The Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC) was formed in December 1991 to operate the Common System of Accounting and Control of Nuclear Materials (SCCC). In April 1994, ABACC and the DOE signed an Agreement of Cooperation in nuclear material safeguards. This cooperation has included training safeguards inspectors, exchanging nuclear material measurement and containment and surveillance technology, characterizing reference materials, and studying enrichment plant safeguards. The goal of the collaboration is to exchange technology, evaluate new technology in Latin American nuclear facilities, and strengthen regional safeguards. This paper describes the history of the cooperation, its recent activities, and future projects. The cooperation is strongly supported by all three governments: the Republics of Argentina and Brazil and the United States

    This work presents an approach for the planning of transmission systems by employing mixed--integer linear programming to obtain a cost and operating characteristics optimized system. The voltage loop equations are written in a modified form, so that, at the end of the analysis, the model behaves as a DC power flow, with the help of the two Kirchhoff`s laws, exempting the need of interaction with an external power flow program for analysis of the line loading. The model considers the occurrence of contingencies, so that the final result is a network robust to the most severe contingencies. This whole technique is adapted to the regional electric power transmission subsystems. (author) 9 refs., 4 figs.

    Full Text Available The article presents the experience of the Institute of Socio-Economic Development of Territories of RAS in conducting sociological research on the territory of the Vologda Oblast and the Northwestern Federal District. It describes the historical aspects of formation of the system for public opinion monitoring and examines its theoretical and methodological foundations. The author of the article analyzes the structure of monitoring indicators and provides a brief interpretation of research findings that reflect social wellbeing and social perception trends. In addition, the paper analyzes people’s attitude toward the activities of federal and regional authorities, trends in social well-being, consumer sentiment and also the complex indicator – the index of public sentiment in the region – developed by ISEDT RAS researchers. The results of sociological studies carried out at ISEDT RAS correlate with the dynamics of the all-Russian public opinion polls conducted by the Institute of Sociology of the Russian Academy of Sciences, the Russian Public Opinion Research Center (VCIOM, Levada-Center, etc. They indicate that Russian society gradually adapts to new conditions of life after the collapse of the USSR. Besides, opinion polls show the most important features of the post-Soviet Russian history at its present stage; they are associated with the intensification of international political relations, the consequences of the “Crimean spring” and the new challenges Russia’s economy is facing now. The article concludes that as global community, of which Russian society is part, is evolving, sociological knowledge begins to play an increasingly important role in administration and national security; this is associated with the greater importance attached to intangible development factors. Therefore, a necessary prerequisite for administration effectiveness in all its stages is to implement the results of sociological research on social

    Natural disasters are extreme sudden events caused by environmental and natural actors that take away the lives of many thousands of people each year and damage large amount of properties. They strike anywhere on earth, often without any warning. A risk maps of natural disaster are very useful to identify the places that might be adversely affected in the event of natural disaster. The earthquakes are one of natural disaster that have the greatest hazards and will cause loss of life and properties due to damaging the structures of building, dams, bridges. In addition, it will affect local geology and soil conditions. The site effects play an important role in earthquake risk because of its amplification or damping simulation. Another parameter in developing risk map is landslide, which is also one of the most important topics in site effect hazards. Palestine region has been suffering landslide hazards because of the topographical and geological conditions of this region. Most Palestine consists of mountainous area, which has great steep slopes and the type of soil is mainly grayish to yellowish silty clay (Marl Soil). Due to the above mentioned factors many landslides have been occurred from Negev south to the northern borders of Palestine. An example of huge and destruction landslide in a Palestine authority is the landslide in the White Mountain area in the city of Nablus, which occurred in 1997. The geotechnical and geophysical investigation as well as slope stability analysis should be considered in making landslide maps that are necessary to develop risk levels of the natural disaster. Landslides occurred in slopes that are created naturally or by human beings. Failure of soil mass occurs, and hence landslide of soil mass happen due to sliding of soil mass along a plane or curved surface. In general, the slopes become unstable when the shear stresses (driving force) generated in the soil mass exceed the available shearing resistance on the rupture surface

    Ana Carolina Magalhães

    2007-12-01

    Full Text Available Regional odontodysplasia (RO is a rare developmental anomaly involving both mesodermal and ectodermal dental components in a group of contiguous teeth. It affects the primary and permanent dentitions in the maxilla and mandible or both jaws. Generally it is localized in only one arch. The etiology of this dental anomaly is uncertain. Clinically, affected teeth have an abnormal morphology, are soft on probing and typically discolored, yellow or yellowish-brown. Radiographically, the affected teeth show a "ghostlike" appearance. This paper reports the case of a 5-year-old girl presenting this rare anomaly on the left side of the maxillary arch, which crossed the midline. The primary maxillary left teeth (except for the canine and the primary maxillary right central incisor were missing due to previous extractions. The permanent teeth had a "ghostlike" appearance radiographically. The treatment performed was rehabilitation with temporary partial acrylic denture and periodic controls. In the future, the extraction of affected permanent teeth and rehabilitation with dental implants will be evaluated. The presentation of this case adds valuable information to pediatric dentists to review special clinical and radiographic features of RO, which will facilitate the diagnosis and treatment of patients with this condition.

    The role of Brazil's state-run petroleum company, Petrobras, in providing a national supply of oil and natural gas and their products to Brazil was discussed. Petrobras is the sole state-run enterprise which carries out research, exploration, production, refining, imports, exports and the transportation of oil and gas in Brazil. Petrobras has built a complete and modern infrastructure made up of refineries, distribution bases, terminals and oil and gas pipelines. Recently (1995) the Brazilian National Assembly approved legislation that while confirming the state monopoly, also provides private contractors and other state-owned companies ways to participate in the petroleum sector. There exists a great potential for oil and gas in many of Brazil's 29 sedimentary basins. The regulatory legislation also created two new organs to deal with the partial deregulation of the petroleum sector, the National Board for Energy Policy and the National Petroleum Agency. The first of these will deal with policy issues, measures and guidelines regarding regional energy supply and demand and specific programs such as those affecting natural gas, fuel alcohol, coal and nuclear energy. The National Petroleum Agency will manage the hydrocarbon sector on behalf of the government. Its functions will include regulation and monitoring of the sector, managing the bidding process for concessions for exploration and production, and other related activities. The new legislation opens up new horizons for the Brazilian oil sector, providing opportunities for private investment, both domestic and foreign, as well as for new technological capabilities associated with these investments. 1 tab., 6 figs

    Full Text Available This paper is a continuation of a study on regionalisation and family, within the project named Sociological Aspects of Multiculturality and Regionalisation and their influence on the development of AP Vojvodina and the Republic of Serbia. The author focuses her attention to operationalisation of the theoretical and methodological premises that were developed in the previous paper (Tripković, 2002: 111-127, which means that it represents the results of the second phase of the research plan. This phase includes adjusting of theoretical concepts to the fieldwork displaying the results of the research and the analysis of the findings that put a family in the context of confronting different identities, above all national and regional. As possible "identity difference" was emphasized in the research, theoretical and methodological apparatus was adjusted to this goal. That is why in this paper the replies of interviewees that can suggest or reject the assumption that their national identity can influence significantly the evaluation of identity specificities are presented and analyzed, concerning more or less visible aspects of family life, like welfare status, relations between spouses, respect to the elder, family harmony, number of children, connections with relatives, etc.

    In conclusion, the successful development and implementation of a multinational nuclear fuel cycle project will require that it be economically viable and satisfy the overlying interests and concerns of the participants. To assure success, it is absolutely essential that the initial planning, development of project criteria, and implementation be based on an authoritative understanding of the real needs of and benefits to all potential participants. The organizational structure for such a project must contain appropriate checks and balances that are sufficient to protect investors, owners, and consumers. Because of its special nature, these checks and balances must also provide for satisfying other important interests, such as an operating organization that addresses nonproliferation concerns and nuclear safeguards. The next logical step in the evolution of regional nuclear complexes is to determine whether such an approach is, indeed, economically viable, financially attractive, and operationally practical. Those who have succeeded in structuring nonnuclear, energy-related complexes currently operating throughout the world today should be looked to for developing the feasibility study of this concept in the nuclear field

    International Nuclear Information System (INIS)

    1993-01-01

    Two paradigms that are the source of present-day economic development policies are described. The dominant paradigm is the expansionist world view that assumes economic growth is essentially unlimited, subject to certain constraints, and that the best way to monitor the human economy is through money flows. The steady-state or ecological world view assumes there are real constraints on material throughput and growth, and puts a significant emphasis on natural capital as a form of wealth which is distinct from economic or manufactured capital. Over the long term, each generation must receive from the previous generation at least an adequate stock of natural capital assets to ensure long-term sustainability. For every major category of consumption, such as food and energy, an ecological footprint can be assigned which represents the land needed to sustain a given pattern of consumption. For the lower mainland of British Columbia, this footprint would be about 22 times the actual land area; for the Netherlands, it would be about 15 times larger than the country itself. On a global basis, only about 1.7 hectares per capita of ecologically productive land is actually available, showing that Canadian material standards would not be sustainable on a global level. The steady-state approach to economic development would involve a local and regional approach from the bottom up, preferring small-scale labor-intensive enterprise. Trade would be limited to trading in real ecological surpluses, and value-added products would be made locally instead of shipping raw materials for processing elsewhere. 5 figs

    A leading economics expert was asked to list the economic advantages and disadvantages associated with electricity exports. This paper presents his expert opinion and presents a regional and economic analysis of the hydroelectric reserves that Hydro-Quebec should maintain in order to ensure long-term reliability of energy supplies while maintaining its potential for profitable exports. Electricity exports from Hydro-Quebec are extremely profitable for the province. From 1999 to 2003, net cumulative exports of 63 TWh brought in 4.2 billion dollars to the province of Quebec. This income was redistributed to Quebecers in the form of low energy prices. From 1994 to 2003, the average annual electricity export from Hydro-Quebec was 18 TWh which represents 11 per cent of all electricity delivered by the producer. Most of this export was sold to short-term markets. This ensures that electricity remains available to Quebec should the need arise. Long term sales agreement have never dominated the utility, and today account for only 1.5 per cent of electricity production. In order to ensure a secure electricity supply, Hydro-Quebec has kept a safety margin of 10 TWh through its large hydro-reservoirs. However, the year 2003 proved to be a difficult year for the producer due to low precipitation. The safety margin was completely consumed and the utility had to import electricity. A theoretical analysis of the market suggests that Hydro-Quebec's safety margin should be increased from 10 to 20 TWh to better meet energy demands during years of low precipitation. 1 tab., 2 figs

  8. Thinking regionally: narrative, the medical humanities and region.

    Science.gov (United States)

    Waddington, Keir

    2015-06-01

    Drawing on multiple literatures from history, geography, anthropology, sociology and literature, this essay asks questions about what we mean by region and why narratives of region should matter to the medical humanities. The essay surveys how region can be used as a lens of analysis, exploring the various academic approaches to region and their limitations. It argues that regions are dynamic but also unstable as a category of analysis and are often used uncritically by scholars. In encouraging scholars working in the medical humanities to be aware that regions are not simple objective or analytical boxes, the essay shows how an awareness of region helps challenge metropolitan whiggism and ideas of core and periphery to give a more prominent place to hinterlands, market towns and rural environments. Furthermore, the essay considers how incorporating region into our understanding of illness can offer new insights. It demonstrates the need for scholars to be attuned to the narratives constructed around regions, suggesting that regions can be viewed as discursive formations that provide a frame for understanding both collective and personal ideas of, and responses to, health and illness, disease and healing, to create what Megan Davies calls a more nuanced 'intellectual cartography'.

    Full Text Available The article deals with such basic definitions as food security, food independence and food self- sufficiency of the region. The author shows the ambiguity problem of interpretations of these terms in the Russian legislation, which is especially evident in the transition from the national to the regional level. Using the example of legislative acts of some of the Russian Federation’s subjects the study demonstrates the incorrect use of mentioned terms. In author’s opinion, regional authorities in the Russian Federation must introduce amendments to the legislative documents concerning food security. To be more concrete, the regional authorities should either deny the goal of food independence for a particular region, or specify that the goal of reaching food independence for the region does not mean food self-sufficiency, but just import substitution on the regional level

    Full Text Available The paper analyzes findings yielded by the empirical study performed in the framework of an RGNF grant entitled “Image of a region as a communicative strategy for the authorities and mass media”. The methods of study included expert survey and formal survey (N=1000, July-September 2013, studying the opinion of respondents who were either internal experts residing in the Volgograd region (N=20; May-September 2013 or external experts who reside outside the region but maintain stable ties with the representatives of state and municipal authorities, regional mass media and business. The findings indicate that the Volgograd region has fallen behind other modernized Russian regions, that young people tend to leave it, that a negative image of the region as a declining territory persists. Answers to the open question “What is unacceptable for you in the existing image of the Volgograd region?” revealed major problems determining the local context of a declining region, and those were issues associated with inefficient regional/municipal administration: “the condition of the roads”, “constant replacement of people in the administration”, “politics as a whole”, “a destitute region without a good manager”, “unemployment”, “countryside is dying off”, “indifference of the authorities”, “roads, housing and public utilities and the administration”, “the authorities are not responsible for the people”, “the authorities do not solve the problems of the city or its people”, “thieving”, “dishonest authorities”, “the region goes to rack and ruin, no kindergartens or jobs”, “one cannot even walk in the streets”, “corruption”, “a stagnant region with low pay”, “no perspectives in the future”, “the region is stagnating due to corruption among officials”.

    Full Text Available OBJECTIVE To analyze the regional governance of the health systemin relation to management strategies and disputes. METHODOLOGICAL PROCEDURES A qualitative study with health managers from 19 municipalities in the health region of Bahia, Northeastern Brazil. Data were drawn from 17 semi-structured interviews of state, regional, and municipal health policymakers and managers; a focus group; observations of the regional interagency committee; and documents in 2012. The political-institutional and the organizational components were analyzed in the light of dialectical hermeneutics. RESULTS The regional interagency committee is the chief regional governance strategy/component and functions as a strategic tool for strengthening governance. It brings together a diversity of members responsible for decision making in the healthcare territories, who need to negotiate the allocation of funding and the distribution of facilities for common use in the region. The high turnover of health secretaries, their lack of autonomy from the local executive decisions, inadequate technical training to exercise their function, and the influence of party politics on decision making stand as obstacles to the regional interagency committee’s permeability to social demands. Funding is insufficient to enable the fulfillment of the officially integrated agreed-upon program or to boost public supply by the system, requiring that public managers procure services from the private market at values higher than the national health service price schedule (Brazilian Unified Health System Table. The study determined that “facilitators” under contract to health departments accelerated access to specialized (diagnostic, therapeutic and/or surgical services in other municipalities by direct payment to physicians for procedure costs already covered by the Brazilian Unified Health System.

    Regions can benefit by offering infrastructure services that are differentiated. Competition between regions over potential investors is then less direct, allowing them to realize greater benefits from external investors. The two polar cases of full and incomplete information about investors' needs are studied. In both cases, there is regional differentiation. However, fiscal competition is efficient in the former case but not in the latter. Finally, it is shown that free entry in the loc...

    2011-01-01

    This paper proposes a general method of extending the effective invisible regions for both the shell-like interior cloak and the complementary media exterior cloak, without affecting their original cloaking regions. The proposed method is based on layered spatial mapping instead of the intact mapping. Certain interior or exterior invisible regions can be obtained by properly using a compressed or folded transformation in each space layer. Therefore, the proposal enables the as-designed cloaks to provide multiple invisible regions of different types simultaneously. Thus objects can be hidden in the interior cavity and/or in the exterior space, or even be embedded between the cloaking shells

    Full Text Available An official statistical dataset for 80 territorial subjects of the Russian Federation for 2000, 2007 and 2009 has proved the hypothesis that, under the neoclassical concept, the resources move to regions with the highest marginal productivity of the factors of production, which leads to the accumulation of investment resources, while providing financial and social efficiency. Based on cluster analysis by three performance criteria, productive regions are identified, which are dominated by regions productive in the extraction of minerals. It is shown that the stability of the factors’ distribution in space determines the current and future specialization of regional economies

The imbalances in the levels of development of various territorial units of Serbia (regional disproportions are the consequence of many structural disharmonies, material limitations, and problems with populationstructure, during many years, all worsened by political and economic events at the end of the twentieth century. Also, in this paper we point out the main characteristics of undeveloped regions, the criteria with which we can define them, and a typology of the municipalities inside each such region.

    Full Text Available Territorial cohesion is an important target of European Union, constantly promoted by its institutions and their representatives. In the context of the Europe 2020 strategy, one of the most important support documents, the region represents a very important issue, being considered to be the key to its successfulness. The region is seen as a support for the smart growth and all the operational policy concepts try to make use of the spatial potential, by taking better account of the territorial specificities. Two main questions play attention: the need to transform the present-day developmental regions into administrative ones is a priority? What kind of regionalization it must to be promoted? Correlating these issues with already defined territorial cohesion, the administrative region is a real tool for the future territorial development. The experience of the last 14 years asks urgently the building of a new territorial administrative reform, giving competences to regions. For instant, each development region is a construction resulted from a free association of the counties. Their role in the regional development is much reduced one, because their regional councils are not elected; decisions taken at this level are consultative for the social, economical, cultural or political actors.

    Directory of Open Access Journals (Sweden)

    Wendy Vaca Hernández

    2017-01-01

    Full Text Available The space called Latin America has a particular history marked by centuries of colonialism and coloniality. The latter concept implies that the basic structure of the colonial system has not changed even though formal independence has been achieved. For this reason, the subcontinent has fluctuated between dependence and the quest for autonomy. These successive cycles have manifested themselves both in the internal configurations and in the regional schemes that have been undertaken. This paper analyzes the construction and evolution of the idea of a region: Latin America and the Caribbean. To that end it examines the concepts of region, regionalism, what Latin America and the Caribbean implies, and what are the transformations in these ideas that have emerged from the regional configurations of the Union of South American Nations (UNASUR and the Community of Latin American and Caribbean States (CELAC as plural organisms with broad objectives.

    A new technology for treatment of contaminated ground water was developed. In this process heterogeneous catalysts (full metal catalyst, mixed oxide catalyst or iron-containing zeolites) in combination with hydrogen peroxide are used. In the reactor catalytic oxidation and aerob biological degradation occur simultaneously. A complete degradation of chlorobenzene was observed in a bench-scale-equipment (2 liter) and also in the pilot plant at the model site located in Bitterfeld (30 liter reactor). The technology can be applied to the ground and waste water treatment. (orig.) [German] Fuer die Behandlung von Grundwaessern, die mit organischen Schadstoffen belastet sind, wurde ein neuartiges Verfahren entwickelt. Bei der katalytischen Oxidation werden heterogene Katalysatoren in Form von Vollmetall-, Mischoxid- und Traegerkatalysatoren in Verbindung mit Wasserstoffperoxid als Oxidationsmittel eingesetzt. In den Katalysereaktoren laufen die heterogen-katalytische Oxidation und der aerob-biologische Abbau nebeneinander ab. Es werden synergistische Effekte erzielt. Mit dem Verfahren wurde in einer bench-scale-Angle (2 Liter) und in der Pilotanlage am Modellstandort in Bitterfeld (30 l Reaktor) der Schadstoff Chlorbenzol vollstaendig umgesetzt.

    Climate change is a global phenomenon with especially harsh effects on the Arctic and northern regions. The Arctic's average temperature has risen at almost twice the rate as elsewhere in the past few decades. Since 1966, the Arctic land area covered by snow in early summer has shrunk by almost a fifth. The Barents Region consists of the northern parts of Norway, Sweden, Finland and Russia (i.e. the European part of Russia). Climate change will cause serious impacts in the Barents Region because of its higher density of population living under harsh climatic conditions, thus setting it apart from other Arctic areas. In many cases, economic activities, like tourism, rely on certain weather conditions. For this reason, climate change and adaptation to it is of special urgency for the region. Regional climate change strategies are important tools for addressing mitigation and adaptation to climate change as they can be used to consolidate the efforts of different stakeholders of the public and private sectors. Regional strategies can be important factors in achieving the national and international goals. The study evaluated how the national climate change goals were implemented in the regional and local strategies and programmes in northern Finland. The specific goal was to describe the processes by which the regional strategies were prepared and implemented, and how the work was expanded to include the whole of northern Finland. Finally, the Finnish preparatory processes were compared to case examples of processes for preparing climate change strategies elsewhere in the Barents Region. This analysis provides examples of good practices in preparing a climate change strategy and implementing it. (orig.)

  17. Croatia in a Regional Context

    Directory of Open Access Journals (Sweden)

    Branko Caratan

    2007-01-01

    Full Text Available In this paper, the author examines the regional context of Croatian politics, highlighting the main reasons for its significance: involvement of the region in war in recent history, the rootedness, aside from that, of extremely strong economic, political and cultural bonds between the countries in the region, and the importance of cooperation in the region for EU accession and further economic development. On these grounds, the author seeks to examine the possibility for stabilisation of the region, and to establish what interests the neighbouring countries such as Italy, Austria, Hungary and others have in strenghtening the bonds with the new democracies in Central and Southeast Europe. All of this eventually provides the answer to the question what is the interest of the EU in this region’s stability and in its admission to the European Union

  18. Dust in H II regions

    International Nuclear Information System (INIS)

    Isobe, S.

    1977-01-01

    Several pieces of evidence indicate that H II regions may contain dust: 1) the continuum light scattered by dust grains (O'Dell and Hubbard, 1965), 2) thermal radiation from dust grains at infrared wavelengths (Ney and Allen, 1969), 3) the abnormal helium abundance in some H II regions (Peimbert and Costero, 1969), etc. Although observations of the scattered continuum suggest that the H II region cores may be dust-free, dust grains and gas must be well mixed in view of the infrared observations. This difficulty may be solved by introducing globules with sizes approximately 0.001 pc. These globules and the molecular clouds adjacent to H II regions are the main sources supplying dust to H II regions. (Auth.)

The originality of the work lies in the work of enriching the SWOT analysis from the author Eve Rajčáková, which is given in the book deals with the issue of Regional development and regional policy of the European Union and Slovakia. Research question: The conditions of life of people in eastern Slovakia. Method: For writing this contribution will be used method of analysis and statistics. Knowledge on this subject have been looking on the internet and in books and sources of information publicly available. Using the data collected, we dealt with the issue of regional development in the Košice and Prešov regions. Results: The topic was the beginning focused on the overall characteristics of eastern Slovakia. Furthermore, we are at work we dealt with social and economic phenomena in both regions of eastern Slovakia. We focused on GDP, unemployment and tourism, which is in the region is widespread. Society: It is well known that there are obviously different living conditions in eastern Slovakia as in other parts of Slovakia. People are forced to, mainly because of employment, leave their region to move or commute to work to the west. The paper point out the right of this negative phenomenon that is quite visible - high unemployment. Limitations: The limits of work are limited by problems of regional development in eastern Slovakia, mainly focusing on economic and social phenomena in the society.

    Full Text Available Searching of sources to increase the capitalization of Russian banks is an important economic problem for both the national and regional economy. Moreover, a strong capital base allows to credit institutions to meet the demands of economic agents for banking service. The research focuses on the choice of sources of regulatory capital for the banks of Tyumen region in the context of changing supervisory requirements in the period of 2005–2016, in different phases of the business cycle. We apply econometric methods of statistical information using IBM SPSS Statistics software. We have calculated the individual correlations of regional banks’ capital with gross domestic product (GDP (excluding gross regional product (GRP and GRP (with the exception of the effect of GDP. These calculations have shown that the capital of regional banks is related only to GDP. The increase in the capital of regional banks is accompanied by a change in its structure: the share of authorized capital has halved, and the share of subordinated debt has grown. All sources of capital, other than the reserve fund, are related to GDP. Authorized capital is associated with the profit of profitable lending institutions; retained earnings in the capital of regional banks — with the aggregated amount of risks of the banking system of the Russian Federation. Subordinated debt, like capital as a whole, is negatively affected by the profitability of the banking sector. The change in the capital of regional banks is determined by the change in retained earnings, subordinated debt and reserve fund. Modelling of these relations has allowed to obtain a system of equations. This system synthesizes linear regression models of changing the capital of regional banks in the context of their sourcing. The results of this study are significant for theoretical justification and practical development of a balanced financial policy of regional banks. Our research will contribute to

The main challenge to the nation is how to adapt these changes that running quite rapidly and outside the country's ability to cope alone. Issues and global structural changes also affect the international system of East Asia region that contains two important sub-Southeast Asia and Northeast Asia. Changes inherent in both these sub certainly affect the foreign policy and diplomacy, security and bilateral relations between Malaysia and other countries. Malaysia is not a global power capable of changing the international system. However, Malaysia is an important country in East Asia that has contributed to the prosperity of this region. The big question is how to adapt these changes into the Malaysia international regional policy and bilateral relations? What extent international issues affecting the regional survival of the country? What is the contribution to regional stability of Malaysia?

  8. Regional Courts as Judicial Brakes?

    Directory of Open Access Journals (Sweden)

    Metcalf Katrin Nyman

    2017-12-01

    Full Text Available The article examines how regional integration courts can act as judicial brakes, at a time when “constitutional coups” – leaders staying in power past constitutional time limits or other forms of actions against the spirit if not always the letter of the constitution – are alarmingly common. The article discusses how regional courts can be used to modify or protect national rule of law and the constitutional order from the outside (i.e. from the regional integration aspect and the extent to which this can be valid particularly to promote a uniform interpretation and application of human rights. Although this trend is visible in Europe, it is more striking, because less expected, on other continents, in particular Africa and the Americas, where the developments take place in less than perfect democratic environments. The article contains evidence from cases dealt with in the various regional courts, supporting that a system of political and judicial oversight, especially in regions with weak or fragile democratic systems, can be a useful addition to national judicial or other mechanisms of protection of rule of law and control of the executive. Action by regional courts helps defeat perceptions of majoritarian politics, which in many countries allow for the winner to take all. Under a system of regional oversight, states become aware of the limits they themselves have set and citizens become aware of their possibilities to challenge political power.

    Full Text Available Regional branding is one of several ways to promote rural regions and support development of socially, culturally and environmentally oriented economies in areas that are interesting due to their natural and cultural heritage. The article attempts to review the conceptual and theoretical underpinnings of branding as conveyed by leading authors in the marketing field. The aim of this paper is to define brand as a broad complex of variables, which are used in building of its identity as a basis for creating value proposition and the position of a brand. Article briefly describes the most comprehensive labeling system for regional products at the micro-regional level is the one guaranteed by Association of Regional Brands (ARB. The main contribution of this article is a theoretical model of strategic management of a regional brand, which captures the interdependence of the individual steps of brand building as well as stakeholders. The starting point for building of brand value is a strategic analysis of the brand, including analysis of customer and competitors. The analysis of external factors is followed by analysis of the brand itself. The resulting relationship between the brand and the customer is based on value proposition representing benefits (functional, emotional, self‑expression. The concept of total product is connected with the concept of total brand and it is offered to the customer as a regional product. Finally it suggests possibilities for further research.

    1999-01-01

    As part of the Department of Energy's research and development effort to improve the monitoring capability of the planned Comprehensive Nuclear-Test-Ban Treaty international monitoring system, Lawrence Livermore Laboratory (LLNL) is testing and calibrating regional seismic discrimination algorithms in the Middle East, North Africa and Western Former Soviet Union. The calibration process consists of a number of steps: (1) populating the database with independently identified regional events; (2) developing regional boundaries and pre-identifying severe regional phase blockage zones; (3) measuring and calibrating coda based magnitude scales; (4a) measuring regional amplitudes and making magnitude and distance amplitude corrections (MDAC); (4b) applying the DOE modified kriging methodology to MDAC results using the regionalized background model; (5) determining the thresholds of detectability of regional phases as a function of phase type and frequency; (6) evaluating regional phase discriminant performance both singly and in combination; (7) combining steps 1-6 to create a calibrated discrimination surface for each stations; (8) assessing progress and iterating. We have now developed this calibration procedure to the point where it is fairly straightforward to apply earthquake-explosion discrimination in regions with ample empirical data. Several of the steps outlined above are discussed in greater detail in other DOE papers in this volume or in recent publications. Here we emphasize the results of the above process: station correction surfaces and their improvement to discrimination results compared with simpler calibration methods. Some of the outstanding discrimination research issues involve cases in which there is little or no empirical data. For example in many cases there is no regional nuclear explosion data at IMS stations or nearby surrogates. We have taken two approaches to this problem, first finding and using mining explosion data when available, and

Formation of balanced local budgets and support of an effective system of managing budget resources is a key to strengthening the economic potential of the regions and increasing the well-being of citizens. The purpose of this article is to assess the current concepts of the fiscal policy of the region in Ukraine and to determine the impact of fiscal policy on the socio-economic development of the regions. Results. In this article the essence and content of budget policy are considered, the interpretation of different scientists is presented. An author’s approach to the definition of the essence of the budget policy of the region as a set of economic and administrative measures in the budget sphere, determined by the interrelated goals and objectives of the state and local self-government, aimed at the socio-economic development of the territory. The conceptual model of the fiscal policy of the region is presented and it is determined that the strategic goal of fiscal policy at the local level should be to ensure sustainable socio-economic development of the territories. The main principles that need to be observed during the implementation of the budget policy of the region are described; functions to be performed by local level fiscal policy; and the main tools by which local authorities carry out their functions. Conclusions. It is noted that the content of the budget policy of the region should be to determine the course, tasks and directions of the state and local self-government activities in the field of the formation and use of budget funds. The budget policy of the region should respond to a combination of the following systemic challenges: 1. the restoration of economic growth, as soon as

    The thesis was aimed to the development of methods for enhanced interpretation of the hydraulic conditions in a groundwater aquifer based on the determination of the Rn-222/Ra-226 ration. Further investigations concerned rocks and rock surfaces (secondary minerals) with respect to the solubility and the mobility of radium in the ground water. The samples were withdrawn in the region of the continental deep borehole (KTB Oberpfalz) and the Czech Republic (Egergraben).

    The rationale for conducting climate change mitigation studies in the transport sector is on the premise that: The transport sector is the second largest consumer of fossil fuels in the region; The regional transport sector is an area with high opportunity for infrastructural development under UNFCCC financial mechanism; The regional transport sector is crucial in the SADC region for trade and coupled with the Trade Protocol will play a major role in development hence the need to make it efficient in terms of energy demand and provision of services; The sector offers many mitigation options but with a challenge to evaluate their energy saving and GHG saving potential and yet there is need to quantify possible emission reduction for possible future emission trading. This is also a sector with potential to qualify for financing through Clean Development Mechanism (CDM) recently stipulated in the Kyoto Protocol. (au)

    We propose a method to study solar magnetic regions in the solar interior with the principle of optical holography. A magnetic region in the solar interior scatters the solar background acoustic waves. The scattered waves and background waves could form an interference pattern on the solar surface. We investigate the feasibility of detecting this interference pattern on the solar surface, and using it to construct the three-dimensional scattered wave from the magnetic region with the principle of optical holography. In solar acoustic holography, the background acoustic waves play the role of reference wave; the magnetic region plays the role of the target object; the interference pattern, acoustic power map, on the solar surface plays the role of the hologram.

    Full Text Available This paper presents partial results of a research on consumer preferences when shopping for groceries. It is focused on regional products and consumer preferences in relation to the country of origin of food products. The main objective of this paper is to find the existence of spatial relationships between spatial deployment of regional products and consumer preferences for regional products. It will be necessary to create a data model for monitoring the deployment of regional products and also a data model for tracking important indicators of consumer behavior in all regions of the Czech Republic. The results are based on questionnaire survey that was conducted within the period from October 2010 to January 2011 on a sample of 3767 respondents from the Czech Republic, via both online questionnaires and their printed version. For the data collection the questionnaire system ReLa, developed by the Department of Marketing and Trade at Faculty of Business and Economics at Mendel University in Brno, was used. Data was processed with statistical software STATISTICA (ver. 10. Spatial visualisation was processed with GIS software ArcGIS (ver. 10.1. Preferences for food of Czech origin were analysed in relation to identification criteria. The research results show that the origin of food has an important role in consumer purchase decision-making. There is no significant difference in importance of this factor based on gender of consumers, however, we could prove moderate dependence on respondent’s occupation, education and age. We could also experience regional differences in levels of preferences of local products or products of Czech origin in regard of 14 regions of the Czech Republic. χ2 (N = 3767 = 245.25; p < 0.001.

In a standard trade model with no distance between countries, a familiar problem of coordination failure arises giving rise to multiple equilibria; any one of many possible trade agreements can form. With distance between countries, and through strategic interaction in tariff setting, regional trade agreements gene...

    Full Text Available As the budgets of the European Union (EU become tighter, the questions about the effectiveness of EU’s expenditure, especially the most important parts such as Cohesion policy, are hotly debated. The aim of this paper is to examine whether the presence of social attitudes may influence the effectiveness of EU budget expenditure, measured by the level of regional inequalities. The analysis starts by focusing on individuals’ attitudes towards income from their own effort and income which is derived from other people’s effort, having in mind that individual actions depend on their attitudes. The next step establishes the link between the income from other people’s effort with the re-distributive dimension of the EU budget, considering that different attitudes among individuals in the EU could lead to significant differences in effectiveness of this redistributive policy among European regions and, consequently, diverse regional inequalities. Empirical research uses data for 27 EU countries observed over two waves of European Value Surveys: 1999-2000 (Wave 1 and 2008–2009 (Wave 2. The results indicate a significant role of social attitudes for regional inequalities, which raises the question of the appropriateness of simplification and uniform regional policy instruments in solving EU regional problems.

    Full Text Available In the article, the authors substantiate the need to consider the regional economic and other conditions when carrying out various essential transformations in the national economy of the country. We have argued the importance of new industrialization for overcoming the technological lag of the country and its regions and for supporting the large-scale structural transformations. We have proved that the complex set of the interconnected concepts and the theories of macro- and microlevels may be the theoretical platform for the paradigm of new industrialization. These are the theory of economic growth, the theory of the modernization of the economy, the theory of the change of technological ways during the industrial revolutions, theories of innovative development, developments in the field of the institutional theory. The authors have shown that the transition to new industrialization is the fundamental historical pattern for the majority of the countries of the world, including industrially developed ones. The purpose of the article is to identify the brightest tendencies and features of the development of the Ural macro-region in the years of market reforms as well as the definition of the strategic transformations in the context of the formation of new industrialization. The hypothesis of the research assumes that the revealed regional features of the Ural macroregion’s economic development are the prerequisites of its development as the centre of the modernization of the Russian economy. On the basis of the analysis of three groups of statistic data for the twenty-five year period of liberal and monetary reforms, the brightest tendencies and features of the development of the Ural macro-region are revealed. We have emphasized that the Ural macro-region has managed to keep its historically developed code — the industrial model of the economy, which have been developing for many decades.

The model has the capability of being run in three modes for a single time period. The three modes are: (1) no deposition, (2) dry deposition, (3) wet and dry deposition. The guide provides the physical and mathematical basis used in the model for calculating transport, diffusion, and deposition for all three modes. Also the guide includes a program listing with an explanation of the listings and an example in the form of a short-term assessment for 48 hours. The purpose of the example is to allow a person who has past experience with programming and meteorology to operate the assessment model and compare his results with the guide results. This comparison will assure the user that the program is operating in a proper fashion

    Danakari Richard A.

    2016-06-01

    Full Text Available The article deals with the complex and controversial problems of the new regional communities’ formation and the impact of the interethnic relations sphere on them. The author notes that the processes of interaction between representatives of different cultures and civilizations, ethnic groups and religions have become increasingly controversial and tense in the context of continuous social dynamics. Similarly to the Russian society as a whole, regional communities are in a state of transitivity. They get transformed, they acquire new qualities such as multicasting and heterogeneity, multi-ethnicity and multi-confessionalism, fragmentarity and multiculturality. This fact increases the risks and uncertainties, problematizes future prospects. National non-governmental organizations are increasingly positioning themselves as civil society institutions at the present stage of social development at the regional level. They perform a difficult dual task: on the one hand, they ensure the preservation and development of history, native language, culture, ethnic traditions, and on the other hand, they work on the integration, on the common identity and the Russian nation formation. On the territory of the Volgograd region, largely due to the active cooperation of regional authorities and local authorities with national public associations, international and inter-confessional relations are stable. The basis of such activity is respect for history, native language, culture, tradition, religion, national dignity of all people in the region, regardless of their belonging to a certain ethnic group or religion. Over two decades of accumulated considerable experience of joint inter-ethnic dialogue and cooperation, provided tolerance and peace, harmony and mutual understanding between people of different ethnicities and religions in the country.

    The Keystone Center convened and facilitated a year-long Dialogue on "Regional Transmission Projects: Finding Solutions" to develop recommendations that will help address the difficult and contentious issues related to expansions of regional electric transmission systems that are needed for reliable and economic transmission of power within and across regions. This effort brought together a cross-section of affected stakeholders and thought leaders to address the problem with the collective wisdom of their experience and interests. Transmission owners sat at the table with consumer advocates and environmental organizations. Representatives from regional transmission organizations exchanged ideas with state and federal regulators. Generation developers explored common interests with public power suppliers. Together, the Dialogue participants developed consensus solutions about how to begin unraveling some of the more intractable issues surrounding identification of need, allocation of costs, and reaching consensus on siting issues that can frustrate the development of regional transmission infrastructure. The recommendations fall into three broad categories: 1. Recommendations on appropriate institutional arrangements and processes for achieving regional consensus on the need for new or expanded transmission infrastructure 2. Recommendations on the process for siting of transmission lines 3. Recommendations on the tools needed to support regional planning, cost allocation, and siting efforts.

    The complex nature of the pathogenesis in hypoxic-ischemic brain injuries equires the combined determination of the dynamics of main factors in these disturbing processes. The application of suitable methods for registration of such pathogenetic processes is shown in an adequate animal model for simulating the early hypoxic-ischemic brain injuries. That the radioactive labelled microsphere technique is suitable to comprehend quantitively the dynamics of the intracerebral redistribution of the circulating blood due to hypoxia/hypercapnia by simultaneous-multiple measuring of the regional cerebral blood flow. Therefore, at the first time an inadequate hypoxic-induced blood flow increase was shown in large parts of the forebrain in intrauterine growth retarded newborn piglets. For estimation of the regional cerebral glucose utilization in newborn piglets, the {sup 18}F-FDG Positron Emission Tomography is introduced. The measurements were carried out on a stationary high-density avalanche chamber (HIDAC) camera and yielded the fundamental application of this camera model for PET investigations also in the newborn brain due to the very good spatial resolution.

    2017-11-24

    Canada has an increasingly large immigrant population. Areas of higher immigrant density, may relate to immigrants' health through reduced acculturation to Western foods, greater access to cultural foods, and/or promotion of salubrious values/practices. It is unclear, however, whether an association exists between Canada-wide regional immigrant density and obesity among immigrants. Thus, we examined whether regional immigrant density was related to obesity, among immigrants. Adult immigrant respondents (n = 15,595) to a national population-level health survey were merged with region-level immigrant density data. Multi-level logistic regression was used to model the odds of obesity associated with increased immigrant density. The prevalence of obesity among the analytic sample was 16%. Increasing regional immigrant density was associated with lower odds of obesity among minority immigrants and long-term white immigrants. Immigrant density at the region-level in Canada may be an important contextual factor to consider when examining obesity among immigrants.

    1979-03-01

    This report has data on population, administration, finance, housing, health and safety, human services, education, and water and sewage for 325 energy-impacted communities. A review of current and potential energy developments in the region shows over 900 energy resource impacts listed for the 325 impacted communities. Coal development represents over one-third of the developments listed. Communities reporting coal development are distributed as follows: Colorado (36), Montana (42), North Dakota (61), South Dakota (13), Utah (73), and Wyoming (35). Energy-conversion initiatives represent another high incidence of energy-resource impact, with uranium development following closely with 83 communities reporting uranium development impact in the region. These projections indicate continued development of regional energy resources to serve national energy requirements. The 325 impacted communities as reported: Colorado (46), Montana (73), North Dakota (62), South Dakota (21), Utah (80), and Wyoming (43) follow a distribution pattern similar to that of future projects which illustrates that no area of the region will escape the impacts of energy development.

    2006-01-01

    The Republic of Korea follows a well-established nuclear nonproliferation policy and could consider regional cooperation as proposed by many nuclear experts over the years. Real problems exist in establishing cooperation, but as the nuclear industry continues to grow, the motivation increases. The US should be a partner in the regional cooperation also. This paper summarizes significant advances made by the NNCA in applying remote monitoring technologies to support international safeguards in the ROK, providing the technical foundation for the use of these technologies for transparency between partner countries. Concrete steps are proposed to form an institutional and then a governmental approach for transparency in the use of nuclear material and even, eventual establishment of a regional safeguards inspection regime.

    1995-01-01

    This paper discusses whether and how security assurances affect political stability in geographic regions. Before embarking on what is necessarily a limited analysis of a complex subject, I point out that the subject is by no means new. For centuries, vast areas of the world have been affected by forces used against them by more powerful States, which at one time or another incorporated large parts of them into overseas colonies or contiguous empires. The new factors are the emancipation of those areas into independent regions, made up of States that play their own parts in international affairs, and the possession by a handful of Powers, outside or on the edge of those regions, of a specific form of superior force: nuclear weapons.

    This paper explores the potential drivers behind uneven regional development in the context of employment growth in Denmark and Sweden. In particular, we are interested in the roles of urbanization, industrial change and the rise of the new economy as manifested in the growth of the two economies...... in 2002–2007. The aim of this paper is, therefore, to analyse the impact of a number of key industrial sectors on regional employment growth in the two countries. The empirical analysis is based on longitudinal matched employer–employee data retrieved from official registers in each economy from 2002...... economies, we find that, although in general these economies react relatively similarly to changes, embarking on a narrower analysis of the individual sectors reveals marked national differences. This indicates that context matters in the analysis of regional economic dynamics in terms of structure, system...

  4. Regional indexes for France. Methodology

    International Nuclear Information System (INIS)

    2006-01-01

    According to the U.S. Department of Energy, an estimated 25% of the GNP is affected by weather-related events. The variations in temperature - even small ones - can also have long-lasting effects on the operational results of a company. Among other, the Energy supply sector is sensitive to weather risks: a milder or harsher than usual winter leads to a decrease or increase of energy consumption. The price of electricity on power trading facilities like Powernext is especially sensitive to odd changes in temperatures. Powernext and Meteo-France (the French meteorological agency) have joined expertise in order to promote the use of weather indices in term of decision making or underlying of hedging tools to energy actors, end users from any other sector of activity and specialists of the weather risk hedging. The Powernext Weather indices are made from information collected by Meteo-France's main observation network according to the norms of international meteorology, in areas carefully selected. The gross data are submitted to a thorough review allowing the correction of abnormalities and the reconstitution of missing data. Each index is fashioned to take into account the economic activity in the various regions of the country as represented by each region's population. This demographic information represents a fair approximation of the weight of the regional economic activity. This document presents the calculation methodology of regional weather indexes for France. Each regional index covers an homogenous area in terms of temperature represented by the biggest city. Five reference cities are used to represent the 22 economical regions of France (Paris Orly, Lyon, Marignane, Bordeaux and Strasbourg). (J.S.)

  5. Social Facilitation: the Kaliningrad Region and Russian Mainland Regions

    2015-03-01

    Full Text Available The authors look at the concept of social facilitation as a possible component of Russian social consolidation in the course of social reforms. The article focuses on the results of an empirical study of the levels and characteristics of competence in social facilitation, which is here understood as the ability to apply certain knowledge and systems of skills and as a success rate of actions based on experience in improving the conditions of social development. The study was conducted in the Kaliningrad region in 2012—2013. The data was obtained through a survey of 400 respondents using the authors’ methodology encompassing eight basic elements of competence and a structured interview aimed at a better understanding of the subject of the study and attitudes towards it. The data is compared against the results of a similar study in two regions of central Russia with similar conditions. The results suggest a disharmonic and inconsistent structure of competence in social facilitation, low motivation for social activity in youth, and a narrow range of ideas about possible areas of personal activities in the current conditions. Gender differences are identified in the level and structure of competence. The authors believe that certain differences in competence components identified through mathematical methods are determined by the geographical characteristics of the Kaliningrad region — its exclave nature, a relatively small territory, and proximity to the EU countries. It is stressed that the regional conditions affecting motivation, forms and areas of activities, and structure of experience should be taken into account in selecting means and methods of organising youth activities. They can also serve as a basis for the regional youth policy.

  6. Regional cooperative agreement for the Asia and Pacific region

    Among the means available to the International Atomic Energy Agency to promote cooperative efforts in the nuclear field is the Regional Cooperative Agreement (RCA) for Research, Development, and Training related to Nuclear Science and Technology for the Asia and Pacific Region. Under the terms of this agreement, which came into force on June 12, 1972, participating countries aim to promote and coordinate research, development, and training projects in nuclear fields through collaborative efforts among relevant national institutions in the region. The Agency's role is to provide organizational, administrative, advisory, technical, and financial assistance when needed to secure successful execution of the projects undertaken within the framework of the RCA. Although this presentation deals primarily with the benefits of regional cooperation under the agreement, a review of the RCA would be somewhat imbalanced without a mention of its shortcomings. One of the principal impediments to more rapid progress, as is the case in many other areas, is financing. There is no stable source of funding outside the research contract program and, the likelihood of large-scale UNDP support notwithstanding, a greater willingness on the part of participating Member States to support the program along with the development of a greater sense of common purpose are called for. In this connection serious consideration is being given to the possibility of establishing an Asian Centre for Research and Training, an institute that would bring together scientists from the region to collaborate on problems common to the RCA countries. A study group has already been convened to investigate the feasibility of this proposal

    Full Text Available The geospatial absorptions are characterized by a specific complexity both in content and in their phenomenological and spatial manifestation fields. Such processes are differentiated according to their specificity to pre-absorption, absorption or post-absorption. The mechanisms that contribute to absorption are extremely numerous: aggregation, extension, diffusion, substitution, resistivity (resilience, stratification, borrowings, etc. Between these mechanisms frequent relations are established determining an amplification of the process and of its regional effects. The installation of the geographic osmosis phenomenon in a given territory (a place for example leads to a homogenization of the geospatial state and to the installation of the regional homogeneity.

    Patients with deep mycoses diagnosed in dermatologic clinics of Manaus (state of Amazonas, Brazil) were studied from November 1973 to December 1983. They came from the Brazilian states of Amazonas, Pará, Acre, and Rondônia and the Federal Territory of Roraima. All of these regions, with the exception of Pará, are situated in the western part of the Amazon Basin. The climatic conditions in this region are almost the same: tropical forest, high rainfall, and mean annual temperature of 26C. The deep mycoses diagnosed, in order of frequency, were Jorge Lobo's disease, paracoccidioidomycosis, chromomycosis, sporotrichosis, mycetoma, cryptococcosis, zygomycosis, and histoplasmosis.

    Among various two-phase flow regimes, the inverted flow in the post-dryout region is relatively less well understood due to its special heat transfer conditions. The review of existing data indicates further research is needed in the areas of basic hydrodynamics related to liquid core disintegration mechanisms, slug and droplet formations, entrainment, and droplet size distributions. In view of this, the inverted flow is studied in detail both analytically and experimentally. Criteria for initial flow regimes in the post-dryout region are given. Preliminary models for subsequent flow regime transition criteria are derived together with correlations for a mean droplet diameter based on the adiabatic simulation data

    The subsequent development of the phenomenological model of the solar convective zone is carried out. The cophasal region, in which unilateral movement of the matter is supposed, is considered. Quantitative relations for kinematic parameters of solar sport groups, agreeing well with the observations, are given. The cophasal regions distribution due to their linear dimensions is obtained. It is shown that the effective depth of the convective zone is found to change with the phase of the activity cycle: less in the minimum and more in the maximum of activity.

    1976-01-01

    The Pacific Northwest (comprised of the states of Alaska, Idaho, Montana, Oregon, Washington and Wyoming) can by several measures be regarded as a national warehouse of fossil energy resources. This condition coupled with an evolving national policy stressing utilization of fossil fuels in the near term prior to development of more advanced technologies for energy supply, could result in the imposition of major changes in the region's environmental, socioeconomic and possibly health status. The objective of the Pacific Northwest Regional Assessment Program is to establish and exercise an integrated analytical assessment program for evaluation of these potential changes that may result from various energy development or conservation scenarios. After consideration of a variety of approaches to integrated assessment at a regional level, Pacific Northwest Laboratories (PNL) has concluded that dynamic simulation techniques provide the best available approach to evaluating the issues pertinent to the Northwest. As a result, the PNW Regional Assessment Program has been structured in a framework involving ten sectors. Each of these sectors involve their own submodels that receive information either from outside the model as exogenous inputs or from other sector submodels

    2017-01-01

    Ecological overshoot has been accelerating across the globe. Optimizing biocapacity has become a key to resolve the overshoot of ecological demand in regional sustainable development. However, most literature has focused on reducing ecological footprint but ignores the potential of spatial optimization of biocapacity through regional planning of land use. Here we develop a spatial probability model and present four scenarios for optimizing biocapacity of a river basin in Northwest China. The potential of enhanced biocapacity and its effects on ecological overshoot and water consumption in the region were explored. Two scenarios with no restrictions on croplands and water use reduced the overshoot by 29 to 53%, and another two scenarios which do not allow croplands and water use to increase worsened the overshoot by 11 to 15%. More spatially flexible transition rules of land use led to higher magnitude of change after optimization. However, biocapacity optimization required a large amount of additional water resources, casting considerable pressure on the already water-scarce socio-ecological system. Our results highlight the potential for policy makers to manage/optimize regional land use which addresses ecological overshoot. Investigation on the feasibility of such spatial optimization complies with the forward-looking policies for sustainable development and deserves further attention.

  3. GLOBALIZATION & REGIONALIZATION IN INTERNATIONAL TRADE

    Directory of Open Access Journals (Sweden)

    Ramona Frunză

    2009-12-01

    Full Text Available The concept of globalization refers to the growing interdependence of countries, resulting from the increasing integration of trade, finance, investments, labor markets and ideas in one globalmarketplace. The most important elements of this process are the international trade and the cross-border investment flows. Economic globalization has increased the specialization of workers, while the companies compete in global markets. Even globalization has recently become a common topic in academic discourse, many economists focused, from the 1980s and 1990s, in addition to globalization, on regionalization - the growth of networks of interdependence within multinational regions of the world. The recent decades arecharacterized by the fact that the world trade grew faster than world output, which implies that an increasing share of world GDP crosses international borders. The trend is explained, mostly, by thesubstantially declining of the trade barriers during the same period, as a result of successive trade negotiation rounds under the auspices of the GATT/WTO, unilateral trade liberalization and regional tradeagreements. Even there are global connections between all the countries, the strongest political and economic integration is being created within a few specific regions of the world: Europe, North America and East Asia.

    1982-09-01

    6 countries in the English-speaking Caribbean (Antigua, Barbados, Dominica, St. Kitts/Nevis, St. Lucia, and St. Vincent) are scheduled to form the 1st regional contraceptive social marketing program. The program will be under the auspices of the Barbados Family Planning Association. By combining resources, contraceptive social marketing should be able to effectively augment family planning activities in smaller countries where individual programs wuld be too costly. The regional program will also determine whether program elements from 1 country in a region are relevant in other countries. The Caribbean region as a whole has experienced a general decline in both crude birth rates and fertility rates during the past 15 years; however, adolescent fertility rates remain high and an average of 46% of the populations of Caribbean countries are under 15 years of age. Although heavy emigration has traditionally curbed population increases, new restrictive immigration laws are expected. Further increases in the working age population will contribute to already high unemployment rates and hinder economic development. The 6 countries selected for the social marketing program are receptive to innovative family planning approaches and have the basic marketing infrastructure required. Community-based distribution programs already in operation in these countries distribute condoms, oral contraceptives, and barrier methods. The success of these programs has plateaued, and there is a need for delivery systems capable of reaching broader segments of the population. The social marketing program will be phased in to ensure local acceptance among national leaders and consumers. The regional program hopes to borrow elements from Jamaica's contraceptive social marketing program to avoid the costs involved in starting a program from scratch. A major innovation will be the use of mass media advertising for contraceptives.

    Full Text Available Sustainable development of administrative-territorial units (ATU refers to the main directions of Russian Federation state policy to ensure the security of the national economy to meet the vital needs of people and the preservation of such a possibility for the future generations. The article describes and analyzes the factors that have the most significant impact on the level of ATE development. The dynamics of the gross output of agriculture in Russia and its critical evaluation are presents. It was revealed that the development of the region is the basis of the national economy security. At present, the concept of “sustainable development” in Russia is relevant and the role of regions in the sustainable development of the Russian Federation is constantly increasing. Stability of self-financing of the regional economy is achieved through conducting effective fiscal, financial, credit, tax and price policy, establishment of equal inter-budgetary relations with the federal center, the development of the securities market, increasing the volume of exports. Conducted research allowed: to identify the main factors influencing the sustainable development of Russia regions. The reasons for the backlog of economy of the Smolensk region of the nationwide growth rate and direction of their elimination are examined. Formation of the forecast of domestic agriculture development in the period up to 2020 should be based on the priority position of the industry in the agricultural sector, which is determined by its decisive role in meeting the population’s needs for basic food products. Prospective volumes of production of major agricultural products are based on the need to meet the challenges provided by the Russian Federation Government Decree.

    We investigated the enhancement of the liver, the spleen, and of induced abscesses and the abdominal vessels after administration of 3 g/kg bodyweight Perfluoroocytlbromide (PFOB) on an animal model. Twenty-one rabbits each received the contrast medium as bolus injection and as slow infusion over half an hour. CT was performed between 2 and 48 hours after contrast medium application. Peak enhancement of the liver, the spleen and the liver abscess membrane was found between 24 and 48 hours after PFOB administration, independently of the application mode. Peak enhancement of the abdominal aorta and the IVC was observed within two hours after bolus injection. In this rabbit model PFOB permits best delineation of the vessels after bolus injection within the first two hours, while CT imaging of the liver, the spleen and the liver abscess membrane is best between 24 and 48 hours after contrast medium application, independent of the injection velocity.

    Full Text Available The article deals with the methodical approach to the assessment of a level of development of post-industrial and neoindustrial models of economic modernization in regional aspect on the basis of various indicators. The proposed approach is approved with use of the statistical materials characterizing the state of economy in the regions of Donbass. The strategy of development of Donbass areas and their industrial cities would have to be based (we mean the situation if there were no military operations on this territory on the basis of the model of neoindustrialization assuming development of the sphere of the hi-tech industry, automation and a computerization of productive forces, replacement of physical work by intellectual labor that is radically capable to change nature of work and structure of labor balance of this macro-region. Branches and sectors of a socio-economic complex of the Donbass region using achievements of fundamental and applied science, engineering and design thought for increase in a share of automation, a computerization and mechanization of workplaces, physical and brainwork prior to the beginning of a political conflict in Ukraine have the potential of development. The authors also pay attention to need of studying the agglomerative effect from interaction of the cities and areas of the Donbass euroregion. It is connected, first of all, with development of vertical and horizontal mechanisms of active use of potential of so-called “cities-kernels”, capable to make the catalyzing impact on production, social infrastructure, creation and development of new perspective branches in the cities-satellites.

    2006-11-01

    Full Text Available Este trabajo se propone analizar las implicaciones del desarrollo en los niveles macro-regional, local y micro- regional, a partir de la hipótesis central de la teoría del desarrollo que plantea que el desarrollo económico traerá consigo el desarrollo político y social. Después de hacer de un acercamiento conceptual al desarrollo, se repasan brevemente las teorías del desarrollo existentes como herramientas de análisis de la realidad. En la discusión se concluye que los procesos de desarrollo locales y regionales requieren de una transformación sustancial de las relaciones negociadas entre los agentes económicos y los actores políticos. Ante el paulatino retroceso que en las sociedades contemporáneas está teniendo el Estado de bienestar, uno de los principales retos es el empoderamiento de las organizaciones sociales y comunitarias para que desempeñen activamente su rol en los procesos de desarrollo local y regional.

    Background concentrations of eleven elements in tissues and organs of wild-living rats (Rattus norvegicus) obtained from a region (Euroregion Neisse, around the trilateral border region of Germany, Poland and the Czech Republic) distinguished by low to intermediate levels of environmental contaminations are given in part I of this work. In order to identify the most important depot compartments for certain elements, a body burden method was applied. Differences of affinity due to sex and age of analyzed rats are discussed, as are the suitability of specific organs and tissues with regard to bioaccumulation measurements concerning metals. The principal depot compartments for the heavy metals Cu, Mn, Cd, (in adult rats) and Tl are the liver and kidneys, whereas the elements Ni, Sr, Pb (for adult animals) and Ti are more affinitively to bones. Co and Zn displayed a more pronounced affinity towards tissues of the bones and liver. The analysis revealed large differences in Cd and Pb distributions both among young and adult rats, and with respect to sexes. It can be concluded that the distribution of the elements investigated in this study in free-living rats agrees with that in man, except for that of Ni. The above agreement gives proof of the possibility to use depot organs of rats for bioindication which was already mentioned in part I of this work.

    In order to establish how organisms can be kept with low stress or free of stress in the laboratory, test species from the Oberlausitz region were chosen. The species belong to the groups of soil-living organisms Collembola, Isopoda, and Gastropoda. Keeping results may be considered as confirmed and as suitable for stress investigations. Successful optimization of keeping is only possible for a single species in each case (generalists excepted).- As applicable vital parameters both to confirm keeping success and to assess the impact of sublethal doses of stressors (heavy metals, insecticides), the following were established (in this order of sequence): reproductive success, growth (change of biomass, sloughing), mortality and, with restrictions, activity (running and foraging activity).- As expected, the effect of the heavy metals used was found to depend on their concentration. Increased mortality as a rule was only found in the wake of cadmium contaminations; reduced growth and, especially, reduced reproduction was triggered also by lead and zinc contaminations. With this regard, subtle differentiations were established. Use of Lindan in the specified dosage proved to have almost no impact during the (short) test period. (orig./MG)

    The present report shows investigations, which have been carried out in a closed duct at forward and backward facing steps. Distribution of fluid velocity and fluid fluctuations in and normal to main flow direction as well as the distribution of Reynolds shear stress have been measured. The mass transfer downstream of a backward facing step has been investigated as well. By using graphite-, copper-, tin- and rubber dust, conditions of deposition have been defined experimentally. A serie of photos shows the filling of a recirculation region downstream of a backward facing step with graphite dust. The present investigations allow to avoid deposition of dust in recirculation regions by selecting the fluid numbers in an appropriate way. (orig.) [de

    The general principle behind the marine cloud brightening (MCB) climate engineering technique is that seeding marine stratocumulus clouds with substantial concentrations of roughly monodisperse sub-micrometre-sized seawater particles might significantly enhance cloud albedo and longevity, thereby producing a cooling effect. This paper is concerned with preliminary studies of the possible beneficial application of MCB to three regional issues: (1) recovery of polar ice loss, (2) weakening of developing hurricanes and (3) elimination or reduction of coral bleaching. The primary focus is on Item 1. We focus discussion herein on advantages associated with engaging in limited-area seeding, regional effects rather than global; and the levels of seeding that may be required to address changing current and near-term conditions in the Arctic. We also mention the possibility that MCB might be capable of producing a localized cooling to help stabilize the West Antarctic Ice Sheet.

    Thyroidectomy is usually performed under general anaesthesia with endotracheal intubation. Bilateral cervical plexus block has been occasionally used as sole anaesthesia technique for this operation in certain parts of world. Indications for regional anaesthesia elsewhere in the world are patient's preference and associated marked cardio-respiratory disease. This is the first report of thyroidectomy done solely under bilateral cervical plexus block in Pakistan. The patient had thyroid cancer and was medically compromised due to cardiac failure with ejection fraction of 25%. Bilateral cervical plexus block was performed to avoid the high risk with general anaesthesia. Total thyroidectomy was done while patient remained painfree during the procedure and top-up local anaesthetic infiltration was not required. Patient remained stable without any morbidity. Positive experience from this case indicates that regional anaesthesia with monitored anaesthesia care is safer than general anaesthesia in high risk patients and could be offered to selective thyroidectomy candidates.

    The Southeast Regional Carbon Sequestration Partnership's (SECARB) Phase I program focused on promoting the development of a framework and infrastructure necessary for the validation and commercial deployment of carbon sequestration technologies. The SECARB program, and its subsequent phases, directly support the Global Climate Change Initiative's goal of reducing greenhouse gas intensity by 18 percent by the year 2012. Work during the project's two-year period was conducted within a ''Task Responsibility Matrix''. The SECARB team was successful in accomplishing its tasks to define the geographic boundaries of the region; characterize the region; identify and address issues for technology deployment; develop public involvement and education mechanisms; identify the most promising capture, sequestration, and transport options; and prepare action plans for implementation and technology validation activity. Milestones accomplished during Phase I of the project are listed below: (1) Completed preliminary identification of geographic boundaries for the study (FY04, Quarter 1); (2) Completed initial inventory of major sources and sinks for the region (FY04, Quarter 2); (3) Completed initial development of plans for GIS (FY04, Quarter 3); (4) Completed preliminary action plan and assessment for overcoming public perception issues (FY04, Quarter 4); (5) Assessed safety, regulatory and permitting issues (FY05, Quarter 1); (6) Finalized inventory of major sources/sinks and refined GIS algorithms (FY05, Quarter 2); (7) Refined public involvement and education mechanisms in support of technology development options (FY05, Quarter 3); and (8) Identified the most promising capture, sequestration and transport options and prepared action plans (FY05, Quarter 4).

    China has experienced an outstanding economic expansion during the past decades, however, literature on non-monetary metrics that reveal the status of China's regional economic development are still lacking. In this paper, we fill this gap by quantifying the economic complexity of China's provinces through analyzing 25 years' firm data. First, we estimate the regional economic complexity index (ECI), and show that the overall time evolution of provinces' ECI is relatively stable and slow. Then, after linking ECI to the economic development and the income inequality, we find that the explanatory power of ECI is positive for the former but negative for the latter. Next, we compare different measures of economic diversity and explore their relationships with monetary macroeconomic indicators. Results show that the ECI index and the non-linear iteration based Fitness index are comparative, and they both have stronger explanatory power than other benchmark measures. Further multivariate regressions suggest the robustness of our results after controlling other socioeconomic factors. Our work moves forward a step towards better understanding China's regional economic development and non-monetary macroeconomic indicators.

  8. Wind power in Arctic regions

    Lundsager, P.; Ahm, P.; Madsen, B.; Krogsgaard, P.

    1993-07-01

    Arctic or semi-arctic regions are often endowed with wind resources adequate for a viable production of electricity from the wind. Only limited efforts have so far been spent to introduce and to demonstrate the obvious synergy of combining wind power technology with the problems and needs of electricity generation in Arctic regions. Several factors have created a gap preventing the wind power technology carrying its full role in this context, including a certain lack of familiarity with the technology on the part of the end-users, the local utilities and communities, and a lack of commonly agreed techniques to adapt the same technology for Arctic applications on the part of the manufacturers. This report is part of a project that intends to contribute to bridging this gap. The preliminary results of a survey conducted by the project are included in this report, which is a working document for an international seminar held on June 3-4, 1993, at Risoe National Laboratory, Denmark. Following the seminar a final report will be published. It is intended that the final report will serve as a basis for a sustained, international effort to develop the wind power potential of the Arctic and semi-arctic regions. The project is carried out by a project group formed by Risoe, PA Energy and BTM Consult. The project is sponsored by the Danish Energy Agency of the Danish Ministry of Energy through grant no.

  9. How to teach regional anesthesia.

    Science.gov (United States)

    Bröking, Katrin; Waurick, René

    2006-10-01

    The demand for peripheral nerve blocks and neuroaxial blocks from both patients and surgeons has increased over the last few years. This change in attitude towards regional anesthesia is prompted by the insight that adequate perioperative pain management leads to earlier ambulation, shorter hospital stay, reduced cost and increased patient satisfaction. To avoid serious complications of these techniques structured residency programs need to be available. Until 2004, the Residency Review Committee for Anesthesiology in the United States required a minimum of 50 epidurals, 40 spinals and 40 peripheral nerve blocks during residency. Similarly, the German Society for Anesthesia and Intensive Care required 100 neuroaxial blocks and 50 peripheral nerve blocks. In 2004 the American Society of Regional Anesthesia and Pain Medicine endorsed standardized guidelines for regional anesthesia fellowships which regulate the administrative, equipment and educational demands. This review introduces the reader to the different teaching methods available, including cadaver workshops, three-dimensional videoclips, video filming, ultrasound guidance and acoustic assist devices as well as demonstrating their advantages and disadvantages. Moreover, an overview is given of future residency training programs, which integrate administrative, material and educative demands as well as the teaching means into the daily clinical routine.

    This article is the summary of the 5-afternoon tutorial on insertions for circular machines. Roughly half the course (Part 1) was spent discussing interaction regions, We start by recapitulating basic beam optics including building blocks. This provides the tools to analyze the basic structure of interaction regions and explore the parameter space. This simple example is then successively refined and made more realistic. Examples of realized interaction regions for both hadron and electron machines are shown and their salient features and differences explained. A brief discussion of solenoid-decoupling brings Part 1 to a close. In Part 2 we discussed various utility sections. Dispersion suppressors are presented in detail discussing the principles as well as the practical implementation of flexible suppressors using LEP as an example. Injection schemes, both single-turn and multi-turn stacking, are presented in depth. The matching of wiggler and undulator insertions and a discussion of the impact of these devices on beam parameters closes out Part 2

    From 1981 through 1986, 49 patients with metastatic liver tumors received deep regional hyperthermia in phase I protocols in six major medical centers in the United States. Adenocarcinoma was seen in 80% of patients with colon as the primary site in 26%. The remaining patients had the following histological diagnoses: Soft tissue sarcoma in seven, malignant melanoma in two and transitional cell carcinoma in one. Deep regional hyperthermia treatments with a BSD-1000 annular phased array were given once or twice a week with a total of 167 treatment sessions, mean 3.4 (range 1 to 8). In addition to deep regional hyperthermia, 17 patients received radiotherapy, and 14 received chemotherapy. The median survival for all patients was 25 weeks. Complete response was obtained in two patients and partial response in four patients. An additional ten patients had nominal response. There was no complete or partial response among the 14 hyperthermia alone treated patients. Of the 26 patients who presented with severe pain, five had complete pain relief, five had partial relief and the majority had a lesser degree of pain relief or no pain relief. Acute treatment toxicity consisted of pain in ten, systemic temperature increase to 39 0 C in four tachycardia in two, claustrophobia in one. The majority of patients did not experience acute toxicity. No late toxicity was recorded in this group of 49 patients. (orig./MG)

    Climate Impact Indices (CIIs) are being increasingly used in different socioeconomic sectors to transfer information about climate change impacts and risks to stakeholders. CIIs are typically based on different weather variables such as temperature, wind speed, precipitation or humidity and comprise, in a single index, the relevant meteorological information for the particular impact sector (in this study wildfires and tourism). This dependence on several climate variables poses important limitations to the application of statistical downscaling techniques, since physical consistency among variables is required in most cases to obtain reliable local projections. The present study assesses the suitability of the "direct" downscaling approach, in which the downscaling method is directly applied to the CII. In particular, for illustrative purposes, we consider two popular indices used in the wildfire and tourism sectors, the Fire Weather Index (FWI) and the Physiological Equivalent Temperature (PET), respectively. As an example, two case studies are analysed over two representative Mediterranean regions of interest for the EU CLIM-RUN project: continental Spain for the FWI and Croatia for the PET. Results obtained with this "direct" downscaling approach are similar to those found from the application of the statistical downscaling to the individual meteorological drivers prior to the index calculation ("component" downscaling) thus, a wider range of statistical downscaling methods could be used. As an illustration, future changes in both indices are projected by applying two direct statistical downscaling methods, analogs and linear regression, to the ECHAM5 model. Larger differences were found between the two direct statistical downscaling approaches than between the direct and the component approaches with a single downscaling method. While these examples focus on particular indices and Mediterranean regions of interest for CLIM-RUN stakeholders, the same study

    During the SHIVA (Stratospheric Ozone: Halogen Impacts in a Varying Atmosphere) campaign in Nov. and Dec. 2011 a number of polluted air masses were observed in the marine and terrestrial boundary layer (0 - 2 km) and in the free troposphere (2 - 12 km) over Borneo/Malaysia. The measurements include isoprene, CO, CO2, CH4, N2O, NO2, SO2 as primary pollutants, O3 and HCHO as secondary pollutants, and meteorological parameters. This set of trace gases can be used to fingerprint different sources of local and regional air pollution (e.g., biomass burning and fossil fuel burning, gas flaring on oil rigs, emission of ships and from urban areas, volcanic emissions, and biogenic emissions). Individual sources and location can be identified when the measurements are combined with a nested-grid regional scale chemical and meteorological model and lagrangian particle dispersion model (e.g., CCATT-BRAMS and FLEXPART). In the case of the former, emission inventories of the primary pollutants provide the basis for the trace gas simulations. In this region, the anthropogenic influence on air pollution seems to dominate over natural causes. For example, CO2 and CH4 often show strong correlations with CO, suggesting biomass burning or urban fossil fuel combustion dominates the combustion sources. The study of the CO/CO2 and CH4/CO ratios can help separate anthropogenic combustion from biomass burning pollution sources. In addition, these ratios can be used as a measure of combustion efficiency to help place the type of biomass burning particular to this region within the wider context of fire types found globally. On several occasions, CH4 enhancements are observed near the ocean surface, which are not directly correlated with CO enhancements thus indicating a non-combustion-related CH4 source. Positive correlations between SO2 and CO show the anthropogenic influence of oil rigs located in the South China Sea. Furthermore, SO2 enhancements are observed without any increase in CO

    This paper analyzed the effect of rainfall on hydrological similarity, which is an important step for regional flood frequency analysis (RFFA). For the RFFA, storage function method (SFM) using spatial extension technique was applied for the 22 sub-catchments that are partitioned from Chungju dam watershed in Republic of Korea. We used the SFM to generate the annual maximum floods for 22 sub-catchments using annual maximum storm events (1986~2010) as input data. Then the quantiles of rainfall and flood were estimated using the annual maximum series for the 22 sub-catchments. Finally, spatial variations in terms of two quantiles were analyzed. As a result, there were significant correlation between spatial variations of the two quantiles. This result demonstrates that spatial variation of rainfall is an important factor to explain the homogeneity of regions when applying RFFA.

    Energy supply companies and industrial plants are likely to face new situations due to, for example, the introduction of new energy legislation, increased fuel prices and increased environmental awareness. These new prerequisites provide companies with new challenges but also new possibilities from which to benefit. Increased energy efficiency within companies and increased cooperation between different operators are two alternatives to meet the new conditions. A region characterized by a high density of energy-intensive processes is used in this study to find the economic potential of connecting three industrial plants and four energy companies, within three local district heating systems, to a regional heat market, in which different operators provide heat to a joint district heating grid. Also, different investment alternatives are studied. The results show that the economical potential for a heat market amounts to between 5 and 26 million EUR/year with payback times ranging from two to eleven years. However, the investment costs and the net benefit for the total system need to be allotted to the different operators, as they benefit economically to different extents from the introduction of a heat market. It is also shown that the emissions of CO 2 from the joint system would decrease compared to separate operation of the systems. However, the valuation of CO 2 emissions from electricity production is important as the difference of emitted CO 2 between the accounting methods exceeds 650 kton/year for some scenarios

    The purpose of the present evaluation was to use SIR-C and X-SAR data for forest surveying and assess their suitability for this task. Amongst other work this included the discrimination of forest and non-forest, demarcation of cleared areas within forests, discrimination of different forest types, and assessment of the influence of foliation. The chief steps of the study were the preparation of radar data, accompanying aerial photo evaluation for the extraction of training and verification areas, and detailed signature analysis. Evaluation trials in ``Oberpfaffenhofen`` supertest area yielded unsatisfactory results when it came to discriminating different forest ecosystems. This can be attributed to the very heterogeneous and small-scale structure of the area and the absence of topographically coded X, C, and L band data. In the second study area, located in the ``Bavarian Forest National Park``, geocoded data of all three bands were available in the form of combined products. This permitted using the mask of the local angles of incidence to reduce the influence of relief. In this case distinguishability within wooded regions was also enhanced. A general finding was that ground resolution as it presents to the user is clearly poorer than the nominal resolution. What impressed us most was the high degree of weather-independence of the radar data. All data handled in this study were recorded under conditions that would have made photography impossible.

    Single crystal Ni-base superalloys (SX) are used for blades in fossil fuel fired power plants and aero engines. Here they have to withstand high mechanical stresses at temperatures close to their melting point. The blades are manufactured by a Bridgman type of directional solidification, followed by a multiple step heat treatment. During the dendritic solidification, pores can form due to undissolved gas, macroshrinkage by inadequate gating and microshrinkage caused by poor feeding between dendrites. Additional pores can form in the interdendritic regions during the multiple step heat treatment which follows solidification. It is believed, that these pores form on the basis of a Kirkendall effect which accounts for the fast diffusion of Al atoms away from microstructural regions with non-equilibrium γ/γ' eutectic. During creep, pores can grow and change their shapes. It has been shown, that during creep in the high temperature / low stress regime new pores form, which are smaller than those pores that can be found in the undeformed material. In the present work, the evolution of porosity in the single crystal Ni-base superalloy ERBO/1 during processing and creep is investigated. Quantitative microstructural analyses were performed on metallographic cross sections. Sampling fields of 4500 x 1000 μm{sup 2} were investigated by using a combination of scanning electron microscopy with quantitative image analysis. Interrupted creep tests with a miniature tensile creep specimen were performed with load direction parallel to left angle 100 right angle and left angle 110 right angle direction, respectively. Pore parameters (area, perimeter, Feret's diameter) for individual pores were obtained and two form factors were introduced. The evolution of the compiled statistical distributions of pore parameters and shape factors are discussed. The results are compared to recent findings by Link et al., 2006 and Maelzer et al., 2007. In the present study it was shown

    This report is the first publication produced within the framework of the WEC's Africa Regional Action Plan as part of the 2005-2007 Work Programme. Presently, over 80% of the total energy consumption in Africa is based on traditional biomass used mostly for cooking. This lack of access to modern energy is holding back economic and social development for 1.6 billion people around the world. The situation is particularly grave in sub-Sahara Africa where over 80% of the population lives in rural areas and the average electrification rate is less than 5%. At least 50 million new connections are needed to provide electricity to supply the non-connected areas in Africa. The over 700 million potential customers represented by these new connections provide a major business opportunity. It is now widely recognised that development assistance, bilateral aid, multilateral financing institutions, a multitude of international aid agencies, NGOs and others have failed to make a significant difference. A new approach is required, otherwise the number of people without access to electricity will continue to grow, and none of the Millennium Development Goals set by the United Nations will be achieved. This regional report highlights key factors that affect cooperative energy projects. The geopolitical context, investment climate and appropriate regulation are just as important as the institutional and technical capacity required to execute many of these projects. The report identifies four key benefits of regional integration: improved security of supply and accessibility; increased economic efficiency; enhanced environmental quality and broader development of renewable resources.

    The Solar Active Region Display System (SARDS) is a client-server application that automatically collects a wide range of solar data and displays it in a format easy for users to assimilate and interpret. Users can rapidly identify active regions of interest or concern from color-coded indicators that visually summarize each region's size, magnetic configuration, recent growth history, and recent flare and CME production. The active region information can be overlaid onto solar maps, multiple solar images, and solar difference images in orthographic, Mercator or cylindrical equidistant projections. Near real-time graphs display the GOES soft and hard x-ray flux, flare events, and daily F10.7 value as a function of time; color-coded indicators show current trends in soft x-ray flux, flare temperature, daily F10.7 flux, and x-ray flare occurrence. Through a separate window up to 4 real-time or static graphs can simultaneously display values of KP, AP, daily F10.7 flux, GOES soft and hard x-ray flux, GOES >10 and >100 MeV proton flux, and Thule neutron monitor count rate. Climatologic displays use color-valued cells to show F10.7 and AP values as a function of Carrington/Bartel's rotation sequences - this format allows users to detect recurrent patterns in solar and geomagnetic activity as well as variations in activity levels over multiple solar cycles. Users can customize many of the display and graph features; all displays can be printed or copied to the system's clipboard for "pasting" into other applications. The system obtains and stores space weather data and images from sources such as the NOAA Space Environment Center, NOAA National Geophysical Data Center, the joint ESA/NASA SOHO spacecraft, and the Kitt Peak National Solar Observatory, and can be extended to include other data series and image sources. Data and images retrieved from the system's database are converted to XML and transported from a central server using HTTP and SOAP protocols, allowing

    Radiotherapeutic treatment of patients with tumours in the oral, perignathic, facial, and neck region can lead to considerable complications under irradiation and any time after irradiation if dental aspects are not considered. A dental treatment should therefore be planned in close cooperation with a dental-, oral-, and orthodontic centre before starting radiotherapy. In many cases, a preparing treatment is not possible for important reasons. Therefore, it is very important that patients who are being or have been treated with radiation are dealt with extremely carefully. (orig.) [de

    The European Commission aims to ensure coherence between environmental, climate, energy and industrial policy to create optimal business environments for sustainable growth and innovations, in a way that enhances the competitiveness of European industry, while moving towards a more resource efficient, circular economy. Sustainability needs to be mainstreamed into all areas of industrial policy to help European businesses to unlock first mover advantage and gain a competitive edge. The Dorothy project is inspired by the contents of the “Flagship Initiative for a resource-efficient Europe under the Europe 2020 strategy”. The Dorothy Project is targeted to develop the potential of innovation and research in the four Regions composing the Consortium in the field of Urban Logistics, which represent the specific application topic of the proposal, and is one of the main focuses of attention of the Flagship Initiative. The industrial environnent is the main actor on the research and innovation regional driven Clusters The Dorothy project has achieved the result of setting up three Regional Innovation Clusters in: Valencia – Spain, Lisbon – Portugal and Craiova – Romania, under the mentoring action of the already existing Tuscany Cluster in Firenze. They operate in the field of Urban Logistics. This achievement must be made durable in time and the cooperation among the Dorothy Clusters must be ensured over the time after the end of the project. For this reason, among the other activities carried out by the project, a Memorandum of Understanding (MoU) have been defined and signed among the four Clusters in form of a multilateral and mutual agreement among them.

    A crucial aspect of advancing in renewable energies is the development of affordable decentralized storage systems for the local or regional distribution grid. A technology with great potential is the all-vanadium redox-flow battery (VRFB) with the distinct feature of individual scalable power and capacity. The present work focusses on one of the essential parts in the redox-flow cell; the bipolar plates. By the application of metallic substrates instead of state-of-the-arte graphite composite plates, the design of the cell isn't limited anymore to the mechanical properties or fabrication process of the material. Although metals possess high ductility, which eases the production of such plates, they are prone to corrosion in the high acidic environment of the battery electrolyte. Therefore in this study amorphous carbon coatings (a-C:H) are investigated for corrosion protection. To attain the need of high electrical conductivity the carbon matrices is doped with a metallic element. Preferably refractory metals such as titanium, vanadium, chromium and tungsten were investigated as possible dopants. The electrochemical tests of the samples revealed less degradation the higher the coating thickness was. This can be found on all metallic substrates (material number: 1.4301, 3.7165 and 3.3535). Regarding the hydrogen overpotential, which is an essential value for the suppression of side reactions on the anode, the dominating factor was found to be the sort of doping material as well as the composition of the metallic adhesive layer between coating and substrate. Pores in the coating originate from defects in the substrates as well as from contaminations during the coating process. To understand the degradation mechanism an in-situ-corrosion cell was developed. By the means of these results, delamination could be found to be the predominant factor concerning degradation mechanisms at cathodic potentials. The degradation is initialized at the defects or at the edges

European «cohesion» and «convergence» programs aim to promote Mediterranean housing in order to improve competitiveness, innovation and employment in under-developed regions. The whole SH planning and implementing process implies criticalities that often damage local initiatives. This study of the Calabria Case has pointed out that both public and private entrepreneurs perceive the cumbersome requirements and procedures as ‘unfriendly’ and tend to renounce the incentives. Process management information instruments together with simpler evaluation and certification systems seem to encourage suitable and flexible solutions, reliable results as well as transparency and quality of action.

    Near infrared reflectance spectra for the Aristachus region, obtained using the 2.2m UH telescope at the Mauna Kea Observatory, were reduced and analyzed. The spectra obtained for the central peak, southern floor, southwestern wall, eastern wall, and northwestern wall of Aristachus crater exhibit shallow continuum slopes, relatively strong feldspar bands, pyroxene bands stronger than those typically seen in the spectra of fresh higland features, and pyroxene band centers near l micrometer suggesting the dominance of Ca rich clinopyroxene. The spectrum of the south rim of Aristachus is quite distinct from those of other crater units. The position of Aristrchus on the plateau/mare boundary raises questions concerning compositional variations in crater ejects deposits.

    The Pittsburgh Regional Healthcare Initiative (PRHI) is a coalition of 35 hospitals, 4 major insurers, more than 30 major and small-business health care purchasers, dozens of corporate and civic leaders, organized labor, and partnerships with state and federal government all working together to deliver perfect patient care throughout Southwestern Pennsylvania. PRHI believes that in pursuing perfection, many of the challenges facing today's health care delivery system (eg, waste and error in the delivery of care, rising costs, frustration and shortage among clinicians and workers, financial distress, overcapacity, and lack of access to care) will be addressed. PRHI has identified patient safety (nosocomial infections and medication errors) and 5 clinical areas (obstetrics, orthopedic surgery, cardiac surgery, depression, and diabetes) as ideal starting points. In each of these areas of work, PRHI partners have assembled multifacility/multidisciplinary groups charged with defining perfection, establishing region-wide reporting systems, and devising and implementing recommended improvement strategies and interventions. Many design and conceptual elements of the PRHI strategy are adapted from the Toyota Production System and its Pittsburgh derivative, the Alcoa Business System. PRHI is in the proof-of-concept phase of development.

    The seismic activity in the southern Appalachian area was monitored by the Southern Appalachian Regional Seismic Network (SARSN) since late 1979 by the Center for Earthquake Research and Information (CERI) at Memphis State University. This network provides good spatial coverage for earthquake locations especially in east Tennessee. The level of activity concentrates more heavily in the Valley and Ridge province of eastern Tennessee, as opposed to the Blue Ridge or Inner Piedmont. The large majority of these events lie between New York - Alabama lineament and the Clingman/Ocoee lineament, magnetic anomalies produced by deep-seated basement structures. Therefore SARSN, even with its wide station spacing, has been able to define the essential first-order seismological characteristics of the Southern Appalachian seismic zone. The focal depths of the southeastern U.S. earthquakes concentrate between 8 and 16 km, occurring principally beneath the Appalachian overthrust. In cross-sectional views, the average seismicity is shallower to the east beneath the Blue Ridge and Piedmont provinces and deeper to the west beneath the Valley and Ridge and the North American craton. Results of recent focal mechanism studies by using the CERI digital earthquake catalog between October, 1986 and December, 1991, indicate that the basement of the Valley and Ridge province is under a horizontal, NE-SW compressive stress. Right-lateral strike-slip faulting on nearly north-south fault planes is preferred because it agrees with the trend of the regional magnetic anomaly pattern.

    The device of the present invention can rapidly detect abnormality of a local power region monitor (LPRM) even at a low power region caused such as upon start-up of a BWR type reactor. Namely, the present invention comprises (1) an LPRM detector for measuring neutron fluxes in the reactor, (2) a gamma thermo detector for calibrating the sensitivity of the LPRM detector, (3) a comparison circuit for comparing the detected values of the detectors (1) and (2), and (4) an alarm circuit for outputting an alarm when the comparative difference of the output of the circuit (3) exceeds a predetermined value. Signals of an alarm for a lower limit of the LPRM detector have been issued continuously upon start-up and shut down of the reactor since neutron fluxes in the reactor are reduced. However, the gamma thermo detector is always secured in the inside of the reactor different from a travelling-type incore probe monitor (TIP) disposed so far for the same purpose. Accordingly, the alarm generated upon usual start-up can be eliminated by comparing the detected values of the detector (2) and abnormality of the detector (1) can be rapidly detected by judging the abnormality of the comparative difference.

    The interviews on the epidemiological imaginary, collected within the framework of the project Sebiorec,(1) clearly demonstrate that also in Campania, on the border between the provinces of Naples and Caserta - where the issue of waste and land devastation take forms that are unprecedented compared to any other part of Europe - there is a widespread, strong, sacrosanct demand of participation in environment and health management. The request of deliberative ecological democracy is pressing.(2) There is an urgent need to meet that plethora of rights emerging in the "knowledge society" and in the "risk society" that someone has called "rights for scientific citizenship."(3) This request of the population of Campania, net of local cultural specificity, it is quite similar to that of the people of any other region of Europe. The context in which this request of participation is expressed, however, is quite different. Not only and not just for that real or perceived social pre-modern and familist web that would replace a modern civil society in Campania and all across the Southern Italian regions, but also and especially for some structural causes that we here try to list. Campania is a unique region in Europe - in many ways different even from other regions of southern Italy - due to the conjunction of at least five factors, not independent from each other. 1) The presence of a widespread organized crime which, in many areas, metropolitan and non-metropolitan alike, and especially in the provinces of Naples and Caserta, is a sort of state against the State and has one of its main levers of power and a major source of its wealth in the illegal control of the territory, in its different dimensions (military, but also economic, social and even cultural). 2) A huge social and economic disintegration, exacerbated in the last twenty years by a process of deindustrialization (until the early nineties Naples was the fifth industrial city of Italy, today it is a desert where

    Background. Due to specific war and post-war situation in Balkan region, differences in the number, type, development, biological course, treatment of malignant tumours and its outcome are possible. In order to perceive the situation realistically, it is necessary to gather continuously exact data about malignant tumours and compare them with the data from other European and world countries.The aim of the study was to collect and analyse the data on cancer incidence in the region of Sarajevo city, which represents a symbol of difficult times in the recent past, and to compare it to the incidence in the neighbouring countries. Patients and methods. Data on all newly diagnosed cancer cases, permanent residents of Sarajevo Canton, in the years 1999 and 2000 were collected. Crude incidence rate has been calculated according to the years observed, gender and localizations of the disease The data were compared to the cancer registries of Slovenia and Croatia and were observed in the light of specific local situation. Results. The crude cancer incidence of all sites but skin was the highest in both years and by both genders in Croatia. The incidence of the most common tumours (lung and breast cancer) was similar in all three countries. The differences in the incidence between both genders in the Sarajevo canton were registered in laryngeal and urinary bladder cancer, as well as in bone and cartilage sarcoma. Cervical cancer had extremely high incidence and was high up on the incidence list in the Sarajevo canton, which correlates with the data in developing countries. The incidence of other tumours in the post-war period is reaching expected numbers. Conclusions. It is difficult to identify whether the war and post-war stress, irregular and insufficient nutrition during and after the siege of the city of Sarajevo or some other factor influenced the cancer incidence among exposed population. The prevalence of smoking in the whole region is extremely high, in Bosnia and

    Barbados, St. Vincent, and St. Lucia have joined forces in the world's 1st regional Contraceptive Social Marketing (CSM) effort -- the Caribbean CSM. The Barbados Family Planning Association (BFPS) is overseeing the operation, which begins selling 2 contraceptive pills and a condom in early February. Costs and start-up times were shaved by adopting brand names and advertising materials from Jamaica's highly successful CSM project. Jamaica's popular "Panther" condom and "Perle" oral contraceptive (OC) are being used by the Caribbean CSM project. Perle's 9-year-old package has been redesigned and the Caribbean CSM project also is selling a 2nd, low-dose version called "Perle-LD." The products are manufactured in the US by Syntex as Noriday and Norminest, respectively. But the regional approach's financial gains also had a debit side, most notably a tripling of bureaucratic procedures. Part of project difficulties stem from differences among the 3 Caribbean countries. While sharing a common cultural heritage, St. Lucians speak a patois dialect in addition to the English prevalent on the other islands. The biggest hurdle was overcoming an economic disparity between Barbados and its less affluent neighbors, St. Vincent and St. Lucia. The CSM project decided to try a 2-tier product pricing strategy. In US currency, prices run $1.75 per cycle for both OCs on Barbados, but $1.26 on St. Vincent and St. Lucia. A Panther 3-pack costs 75 cents on Barbados and 42 cents on the othe 2 islands. The project is being promoted with generic family planning media advertisements. The project also has held physician orientation seminars on each island. The pilot program will be accompanied by retailer training seminars. In addition the project may introduce a spermicidal foaming tablet, once the US Food and Drug Administration approvs a new American-made product. The unique Caribbean CSM project may spread an idea as potent as the family planning message. Its success could transmit the

    Full Text Available This study investigates the spatial economic structure and inequality in Thailand at the national and regional levels, with a particular focus on the Northeastern region in the period from 1987 to 2007. The study has three main points: 1 examination of the economic structure and inequality at the national level and in the Northeastern region according to the Theil index, 2 determination of regional growth centres and satellite towns by using growth pole theory as a conceptual framework and incorporating spatial interaction analysis and 3 analysis of the relationship between regional growth centres and satellite towns with regard to the impact on growth and inequality. The results show that the Northeastern region is definitely the lagging region in the nation, by both gross domestic product (GDP and gross regional product (GRP per capita. It was therefore selected for a case study. Spatial analysis identified Nakhon Ratchasima, Khon Kaen, Udon Thani and Ubon Ratchathani as regional growth centres. Each of them has its own sphere of influence (or satellite towns, and the total area of regional growth centres and satellite towns are classified as sub-regions. The development of regional growth centres has a direct impact on sub-regional economic growth through economic and social relationships: urbanisation, industrial development, per capita growth, the number of higher educational institutes and so on. However, such growth negatively correlates with economic equality among the provinces in a sub-region. The inequality trend is obviously on an upswing. This study suggests that industrial links between regional growth centres and their satellite towns should be improved in order for regional growth centre development to have a consistently desirable effect on both economic growth and equality. Such a strong process means that the growth of regional growth centres will spread, leading to the development of their surrounding areas.

    The U.S. DOE Regional Test Center for Solar Technologies program was established to validate photovoltaic (PV) technologies installed in a range of different climates. The program is funded by the Energy Department's SunShot Initiative. The initiative seeks to make solar energy cost competitive with other forms of electricity by the end of the decade. Sandia National Laboratory currently manages four different sites across the country. The National Renewable Energy Laboratory manages a fifth site in Colorado. The entire PV portfolio currently includes 20 industry partners and almost 500 kW of installed systems. The program follows a defined process that outlines tasks, milestones, agreements, and deliverables. The process is broken out into four main parts: 1) planning and design, 2) installation, 3) operations, and 4) decommissioning. This operations manual defines the various elements of each part.

    Full Text Available Echinococcosis, commonly called as hydatid disease, is a parasitic infestation caused by the larva of the genus Echinococcus in human. Isolated occurrence of Echinococcosis without any evidence of visceral disease is very rare. A thorough search of the literature revealed only 11 cases of isolated cervical Echinococcosis. We report here a very rare case of isolated hydatid cyst in a 45-year-old female patient, who presented with swelling in right cervical region about 5 cm below the angle of mandible with no evidence of the disease elsewhere in the body. The case was diagnosed on fine needle aspiration cytology. The diagnosis was further supported by histopathology. We propose that the treating physician should also consider the differential diagnosis of Echinococcosis in the presence of an asymptomatic soft tissue mass, especially when the patient lives in an endemic area.

    In aperture problems, integral equations for equivalent currents are often found by enforcing matching of equivalent fields. The enforcement is made in the aperture surface region adjoining the two volumes on each side of the aperture. In the case of an aperture in a planar perfectly conducting...... screen, having the same homogeneous medium on both sides and an impressed current on one aide, an alternative procedure is relevant. We make use of the fact that in the aperture the tangential component of the magnetic field due to the induced currents in the screen is zero. The use of such a procedure...... shows that equivalent currents can be found by a consideration of only one of the two volumes into which the aperture plane divides the space. Furthermore, from a consideration of an automatic matching at the aperture, additional information about tangential as well as normal field components...

    Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC) was created as a common system of accounting and control. It is based on Bilateral Agreement between the two countries and the agreement with the IAEA. After a few years of experience it might be concluded that a regional system may contribute in many ways to enhance the safeguards system. The most relevant are: to improve the effectiveness and efficiency of safeguards by sending as professionals who are experts in the process involved in installations that are to be inspected; to have much more information on nuclear activities in each of the two countries than available to the IAEA; and to maintain formal and informal channels of communication

    Full Text Available Design of a muon collider interaction region (IR presents a number of challenges arising from low β^{*}<1  cm, correspondingly large beta-function values and beam sizes at IR magnets, as well as the necessity to protect superconducting magnets and collider detectors from muon decay products. As a consequence, the designs of the IR optics, magnets and machine-detector interface are strongly interlaced and iterative. A consistent solution for the 1.5 TeV center-of-mass muon collider IR is presented. It can provide an average luminosity of 10^{34}  cm^{-2} s^{-1} with an adequate protection of magnet and detector components.

    Experimental work on the grid avalanche chamber has been continued. Several aspects of problems related to chamber operation, in particular the efficiency, have been investigated. These include a study of background and noise fluctuations with an effort to decrease and stabilize them, an effort to decrease light leaks, and an effort to determine if the light measured by the photomultiplier tube comes from the gas itself or from the scintillator. Work was also done on measuring coincidences between the solid state detector (which registers alpha particle traversals of the chamber) and the photomultiplier tube output, since all of the necessary electronics have finally been obtained. A study of the shape of equipotentials in the detector region was undertaken and also an apparatus was developed to apply thin coatings in a vacuum system

    There is described a rare case of the abscess localized in the left thalamus of dominant hemisphere of the brain. In case report with review of literature are emphasized advantages of the stereotactic method, which minimally invasively gives a possibility to aspirate even reaspirate abscess in this surgically inaccessible region if initial aspiration and antibiotic therapy proves ineffective. One year after surgery patient is without neurological deficit and follow up MR scans showed complete resolution of the lession. Application of MR methods is essential during diagnostic procedure and for evaluation of efficacy of selected treatment. Stereotactic aspiration is useful method in management of abscesses located in deep – seated or eloquent areas of the brain.

    1996-11-01

    This paper argues that cooperative monitoring plays a critical role in the implementation of regional security agreements and confidence building measures. A framework for developing cooperative monitoring options is proposed and several possibilities for relating bilateral and regional monitoring systems to international monitoring systems are discussed. Three bilateral or regional agreements are analyzed briefly to illustrate different possibilities. These examples illustrate that the relationship of regional or bilateral arms control or security agreements to international agreements depends on a number of factors: the overlap of provisions between regional and international agreements; the degree of interest in a regional agreement among the international community; efficiency in implementing the agreement; and numerous political considerations. Given the importance of regional security to the international community, regions should be encouraged to develop their own infrastructure for implementing regional arms control and other security agreements. A regional infrastructure need not preclude participation in an international regime. On the contrary, establishing regional institutions for arms control and nonproliferation could result in more proactive participation of regional parties in developing solutions for regional and international problems, thereby strengthening existing and future international regimes. Possible first steps for strengthening regional infrastructures are identified and potential technical requirements are discussed.

    Data from the Multi-angle Imaging SpectroRadiometer's vertical-viewing (nadir) camera were combined to create this cloud-free natural-color mosaic of Scandinavia and the Baltic region. The image extends from 64oN, 0oE in the northwest to 56oN, 32oE in the southeast, and has been draped over a shaded relief Digital Terrain Elevation Model from the United States Geological Survey. It is displayed in an equidistant conic projection.The image area includes southern Norway, Sweden and Finland, northern Denmark, Estonia, Latvia and part of western Russia. Norway's rugged western coastline is deeply indented by fjords. Elongated lakes, formed by glacial erosion and deposition, are characteristic of the entire region, and are particularly dense throughout Finland and Sweden. Numerous islands are present, and a virtually continuous chain of small, scattered islands occur between Sweden and Finland. The northern and eastern waters of the Baltic Sea are almost fresh, since the Baltic receives saltwater only from the narrow and shallow sounds between Denmark and Sweden that connect it to the North Sea. Most of the major cities within the image area are coastal, including St. Petersburg, Stockholm, Helsinki, Riga, and Oslo.The Multi-angle Imaging SpectroRadiometer (MISR) observes the daylit Earth continuously from pole to pole, and every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude.MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC.

    Full Text Available The article is dedicated to transforming the economy of Russian regions to a green economy, which is an essential factor for the sustainable development. This is important not only for Russia but the whole world because our country has the great natural capital and provides important environmental services that support the planet biosphere. Based on the analysis of economic, social and ecological statistical data and Human Development Index (HDI we have shown that the development of Russian Federal Districts is very unbalanced and each Russian region has its own way to new economic model. For instance, it is necessary to increase the well-being in the North Caucasus Federal District, it is important to reach higher life expectancy at birth in the Siberian and the Far Eastern Districts. It is necessary to move from the «brown» economy to a green one by using the human capital (building a knowledge economy, by applying Best Available Technologies (Techniques, by investing in efficiency of use of natural resources and by increasing energy efficiency. The transition to a green economy will help to achieve social equity and the development of human potential; it helps to move from the exploitation of non-renewable natural capital to renewable human capital. All these socio-economic measures should give decoupling effect, make risks lower, reduce the exploitation of natural capital, stop the environmental degradation and prevent the ecological crisis. Transition to the green economic model has to be accompanied by new economic development indicators, which take into account social and environmental factors.

    According to WHO hereditary diseases and congenital malformations contribute significantly to the health of population. Thus, the problems of epidemiology, clinical presentation, diagnosis and treatment of congenital abnormalities are of interest for many researchers [2]. In addition, the dynamic accounting for the incidence of congenital malformations and hereditary diseases allows the researchers to assess the ecological situation in the region [1]. The occurrence of congenital anomalies in the world varies; it depends heavily on how carefully the data is collected [4]. Multifactorial or polygenic diseases develop under the influence of environmental factors in the presence of defective genes. They can constitute up to 90% of all chronic pathology [2-5]. To determine the incidence of congenital anomalies under the influence of environmental factors. The study used the methodology of system evaluation of congenital anomalies incidence in Primorsky region, depending on bio-climatic and environmental conditions. The authors used health statistics for the period from 2000 to 2014, F.12 class for congenital abnormalities in adolescents and children that were compared in geographical and temporal aspects with environmental factors of 33 settlements in Primorsky region. The environment is represented by nature and climate (6 factor modules) and sanitation (7 factor modules) blocks of factors. When formalizing the information database of the environment a specially developed 10-point assessment scale was used. Statistical processing of the information was carried out using Pearson's chi-squared test and multiple regression method from SSPS application program package. The study found that over the 15-year period the level of congenital abnormalities in children increased by 27.5% and in adolescents - by 35.1%, and in 2014 it amounted to 1687.6 and 839.3 per 100 000 people, respectively. The predictive model shows a steady further growth of this pathology. The incidence

    The use of nuclear energy demands extensive institutional and material infrastructure upon a foundation of stable intrastate conditions and interstate relations. Conflicts can result in catastrophic accidents, either deliberately or unintentionally. If there are nuclear facilities located in a crisis region, the risk of a nuclear disaster is markedly heightened. This can be explained not only in terms of the strategic relevance of the energy supply in military conflicts, but also the increased accident risks and hazards arising from collateral damage, as well as the erosion of the safety culture and institutional control in crisis regions with a nuclear infrastructure. Even just the escalation of a political dispute or the persistence of low intensity conflicts can make it generally more difficult and complex to maintain nuclear safety, if intrastate safety mechanisms come under strain or even fail as a result. So far no instance of military escalation, past or present, has led to an accident in a civil nuclear facility. Nevertheless, questions are clearly raised about the vulnerability of nuclear facilities in crisis regions and the risks associated with this vulnerability. Despite the potentially far-reaching consequences, too little attention is currently being paid to the linkage between intra- and interstate conflicts and the safety of nuclear facilities in crisis regions. The aim of the research presented here was to explore this theme and, after laying the groundwork in this manner, to raise awareness among policy-makers and the wider public. In this context the escalation of conflicts in the Ukraine is a particular focus. The first part of the report begins with a systematic look at the link between crisis regions and/or conflicts and nuclear safety. The various impact pathways relating to nuclear facility safety and the associated risks are described in relation to potential hazards induced by crises and wars.

    Regional development is very closely related to a region and its competitive advantages which affect the competitiveness of the region. The regional development is influenced by many factors that act differently depending on the region. To ensure the effective and harmonized regional development, the systematic approach is needed. Every region is unique and differs from the other by the level of economic development, living standards of its inhabitants, unemployment rate and by employment possibilities. Regional policy is a strategic investment policy which focuses on all regions and cities in the European Union. The aim is to boost economic growth and to improve the quality of people’s lives. Solidarity is the main feature of the policy, because policy focuses on support for less developed regions. A fundamental aspect of regional development is to reduce disparities between the regions and cities. The paper focuses on the analysis of regional development of Slovakia. The intention is to follow the logical continuity of the article’s parts, the correctness and the adequacy of information and data. First part is focused on the definition of the regional policy and regional development. Important task is to identify the differences between European policies - regional, structural and cohesion policy. This section is prepared by using the analytical methods - the analysis, the casual and historical analysis. This part is based on literature review. The empirical part is based on statistics and secondary analysis which were aimed to analyse the regional development and effectiveness of its planning in the Slovak Republic. The question of this article is whether it is possible to plan the regional development by application of the plan for economic and social development, called the Municipal Development Plan.

Karyotypes of specimens taken from stream pools of the Volga were used as reference samples. The populations of Bryansk and Gomel regions (except for a population of Lake Strativa in Starodubskii district, Bryansk region) exhibit broad structural variation, including somatic mosaicism for morphotypes of the salivary gland chromosome set, decondensation of telomeric sites, and the presence of small structural changes, as opposed to populations of Saratov region. As compared with Saratov and Bryansk regions, the Balbiani ring in the B-arm of chromosome I is repressed in populations of Gomel region. It is concluded that the chromosome set of Ch. plumosus in a range of waterbodies of Bryansk and Gomel regions is unstable.

    Recent prospective studies of male reproductive health have shown differences between several European countries. Our objective was to evaluate the current situation in the two Baltic States Estonia and Lithuania. In 1997-99 we investigated semen parameters, levels of reproductive hormones and general health factors of 196 men from the general population in Lithuania; from Estonia, 79 men from the general population and 118 soldiers were investigated. Adjusted for interlaboratory differences and abstinence period, sperm concentration of Lithuanian and Estonian men from the general populations were shown to be 55 and 67 million/mL, respectively. The Estonian soldiers had the highest sperm concentration, 82 million/mL. The frequencies of morphologically normal spermatozoa were 6.2, 7.7 and 9.6%, respectively. In contrast to the semen qualities, highest Inhibin B levels were detected in the Lithuanians (233 pg/mL) followed by Estonian men from the general population (220 pg/mL) and Estonian soldiers (185 pg/mL). The soldiers had also the lowest level of testosterone and oestradiol. The sperm counts of the Estonian and Lithuanian men investigated here are higher than recently shown for Norwegian, Danish, Estonian and Finnish men. Comparisons should be cautiously drawn as the groups are not completely comparable. Still, even within the Baltic region, geographically close and sharing common recent social history, differences in semen quality and levels of reproductive hormones are apparent.

    Food culture is most influenced by the locality of its origin, which will have been one of food acquisition and processing by various means. It is generally agreed, and is the basis of much United Nations, especially Food and Agriculture Organisation strategic development policy, that successful agriculture, horticulture and aquaculture along with fishing, underpin economically viable and healthy communities with their various food cultures. We also know that this must be in tandem with maternal literacy and operational health care systems. These elements are best represented on a regional basis. There is a growing consumer interest in knowing where one's food comes from as a measure of "food integrity". However, food production alone can be a precarious business and relate to a lesser or greater extent to local food culture and to trade, which may be complementary or at-odds with each other. Likewise, the local food culture may have its strengths and weaknesses as far as its ability to meet nutritional and health needs is concerned. Local food production may be restricted because of geographical or socio-economic conditions which preclude food diversity, although this may be compensated for by trade. Where food adequacy and diversity is compromised, and soils poor, various macronutrient, micronutrient (from animals and plants) and phytonutrient (nutritionally-advantageous food component from plants) deficiencies may be in evidence. These food system problems may be intertwined with food culture--for example, "rice-based and water-soluble vitamin poor"; "few animal-derived foods like meat, fish, eggs and milk with associated low calcium, vitamin D, Vitamin B12 and long chain n-3 fatty acid intakes"; "low fruit and vegetable intake with limited carotenoids and other phytonutrients". Geo-satellite surveillance and mapping as identifying such "hot spots": for regional food problems, as well as hot spots where most of the world's biodiversity is found (1.4 % of land on

    This final report describes the results of the techno-economic accompanying research of the competition of bioenergy regions. The competition was realized as a three-year funding project of the Federal Ministry of Food, Agriculture and Consumer Protection (BMELV), wherein the DBFZ analyzed the bioenergy development in the project regions and effects for regional development. The aim of the techno-economic accompanying research was to evaluate the project regions regarding the use of bioenergy. To this end, the bioenergy plants and supply chains of bioenergy as well as the raw materials used were the focus of investigations. Hereby the comparison between the regions and classification of the national average should be made possible. It was also necessary to be able to make statements about the climate protection contribution of funding the project. Not least the DBFZ supported the office of competition and the regions in answering technical-economic issues. The report is divided into a theoretical part A and the result Part B. After a summary of the results (chapter 1) and a brief overview of important and higher-level indicators (Chapter 2) the background and objectives of the competition are in Part A, first presented (Chapter 3). This is followed by Chapter 4 of the explanation of the methodological approach. Part B contains the results of the accompanying research project. The individual chapters are based respectively on the specific questions or thematic blocks of techno-economic accompanying research (Section 5-8). The final chapter 9 takes a brief look at the second funding phase from 2012 to 2015.

    The D-region of the ionosphere, traditionally defined as the region of ionization below 100 km, is a link between the non-ionized stratosphere below and the dense plasma above. In it, minor neutral constituents play a dominant role and chemical reactions, both neutral and ionic, are dominant. It plays a very important role in the propagation of radiowaves at all frequencies below 30 MHz, and is particularly important in effecting communication over areas of the earth, such as polar regions, that are inaccessible to synchronous satellite links. Work which has been carried out on the neutral environment, D-region ionization, positive and negative ions found in the D-region, disturbances in the D-region (of solar origin and due to local dynamics or thermal changes), and the chemistry of the region, is considered. Possible future D-region studies are outlined. (UK)

    This paper proposes that strengthening regional capabilities for formulating and implementing arms control and confidence-building measures is a tangible method of enhancing regional security. It discusses the importance of developing a regional infrastructure for arms control and confidence building and elucidates the role of technology in facilitating regional arms control and confidence-building agreements. In addition, it identifies numerous applications for regional cooperative monitoring in the areas of arms control, resource management, international commerce and disaster response. The Cooperative Monitoring Center at Sandia National Laboratories, whose aim is to help individual countries and regions acquire the tools they need to develop their own solutions to regional problems, is discussed briefly. The paper ends with recommendations for establishing regional cooperative monitoring centers

    Full Text Available During last several years the Caspian region has to face the integration into global international process. Long and hard process of globalization is connected not only with the dissolution of the USSR and the emergence of new regional players, but also the desire of extra-regional countries to participate, monitor and control all aspects of life in this region, including energy potential, transport, cultural, ecological and strategic issues. The situation is complicated by the uncertainty of the legal status and the conflict of interest of some extra-regional participants. Until recently, Caspian regional countries were not ready to solve old familiar aches without the biggest international players, such as the USA, China, EU etc. However the safety of the region requires decisions for the benefit of the region in the whole and each country separately.
