A new EC standard will be drawn up. Mit dem Inkrafttreten des Gemeinsamen Marktes und der damit zusammenhaengenden Forderung nach Abbau von Handelshemmnissen sollen diese Pruefverfahren harmonisiert werden. Ziel ist es, die an die Foerdergurte zu stellenden brandtechnischen Anforderungen innerhalb der EG zu vereinheitlichen. Es soll deshalb eine europaeische Norm zur Beurteilung des Brandverhaltens und der Brandausbreitung an Foerdergurten fuer den Kohlenbergbau unter Tage erstellt werden.

Weld testing in the fabrication of large-diameter pipes; Schweissnahtpruefung bei der Fertigung von Grossrohren. Wenzel, T. Fully automatic radiographic testing of cast light metal components is a state of the art technology. The contribution describes its application in weld testing. A new method for evaluating X-rays of welds is presented which were tested using an innovative X-ray camera with maximum spatial resolution and a wide range of grey values.

Further, a novel concept for handling test objects significantly shortens testing times. The pipes are not moved longitudinally; instead, the longitudinal motion is made by the X-ray emitter and sensor, which reduces the testing time by up to 30 percent. The specially developed X-ray detector has a sensitive surface of mm x 50 mm with a total of 4. Neither the evaluation electronics nor the light-sensitive camera chip are exposed to the direct X-radiation so that no damage will occur at photoenergies up to at least keV. Many tests , e. The pictures taken by the camera serve as input data for fully automatic evaluation.

All stages of image processing implement bit digitalisation depth in order to make use of the high dynamic range of gray value images. This means that in the whole processing chain, there will be no loss of information from downscaling of the gray values. In the first stage of image processing, the gray values are transformed into penetrated material thicknesses in preparation of the measurement of fault length in the direction of incidence at a later stage.

In the next stage, external boundaries and the middle of the weld are detected, followed by an adaptive filtering stage. Additionally, information on the accurate location of the weld is transmitted to the control system of the mechanical parts, so that optimum positioning of the weld with respect to the camera is ensured. The adaptive filter. Non-destructive testing of concrete structures with the impact-echo method; Zerstoerungsfreie Pruefung von Betonbauteilen mit dem Impact-Echo-Verfahren.

The impact-echo method is based on the use of elastic waves. It was developed in the for the testing of concrete structures and is currently widespread. Main application areas are the component and coating thickness measurement and detection of delaminations, voids and other defects. Specifically, the method is also used to check the injection faults of clamping channels.

Another application is the determination of mechanical material parameters such as the modulus of elasticity. Since the original development of the method has undergone several enhancements. The conversion of a single-point measurement method towards a area component testing , the use by the optimized measurement data acquisition and evaluation enlarged and delivered an important prerequisite for increasing the efficiency.

The use of air-coupled sensors not only increases the measurement speed but also provides advantages in rough component surfaces. The imaging analysis in conjunction with signal processing algorithms simplifies the interpretation and allows statistical evaluation. Es wurde in den er Jahren fuer die Pruefung von Stahlbetonbauteilen entwickelt und ist derzeit weit verbreitet. Haupteinsatzgebiete sind die Bauteil- und Schichtdickenmessung sowie die Detektion von Delaminationen, Hohl- und anderen Fehlstellen.

Insbesondere wird das Verfahren auch zur Pruefung des Verpresszustandes von Spannkanaelen herangezogen. Eine weitere Anwendung ist die Bestimmung mechanischer Materialparameter wie dem Elastizitaetsmodul. Seit der urspruenglichen Entwicklung hat das Verfahren verschiedene Weiterentwicklungen erfahren. Die Ueberfuehrung von einem Einzelpunktmessverfahren hin zu einer flaechigen Bauteilpruefung hat die Einsatzmoeglichkeiten durch die optimierte Messdatenaufnahme und -auswertung vergroessert und eine wichtige Voraussetzung zur Erhoehung der Leistungsfaehigkeit geliefert.

Auswahl von Testorganismen zur Bestimmung der Toxizitaet von Dispergatoren bei der Oelbekaempfung in marinen Gewaessern. Several marine organisms were investigated regarding their qualification for oil dispersant toxicity determination. Appropriate organisms were chosen for two different test procedures: Using mortality as a test criterion an acute toxicity test can be carried out very easy with larvae of the brine shrimp Artemia sp. The sensitivity for different dispersants ranges over several orders of magnitude.

Another test indicator is the cell multiplication-inhibition test , conducted with the microalga Scrippsiella trochoidea, a representative of phytoplankton. The sensitivity for a common dispersant ranges a hundredfold higher than the acute toxicity test. Both test procedures are also practicable for other water-soluble substances, as well.

One oil-spill dispersant efficiency test is proposed provisionally. With 62 refs. Ultrasonic testing of core baffle former bolts of the core tanks of pressurised water reactors; Ultraschallpruefung von Kernumfassungsschrauben der Kernbehaelter von Druckwasserreaktoren. Bies, Christian M.

This is a remotely operated underwater vehicle which positions ultrasonic probes under camera control. This vehicle makes it possible to substantially reduce the time required for setting up and preparing ultrasonic tests on core baffle former bolts. It has also accelerated the test procedure itself. Test methods have also been developed for bolt types which were hitherto considered incapable of being tested. One of these methods is based on a phased array probe.

The article also reports on experiences gained over the course of years in testing core baffle former bolts in European nuclear power plants using the SUPREEM testing robot. Predicting the durability of mineral external plaster using accelerated ageing tests ; Prognose der Dauerhaftigkeit mineralischer Aussenputze mit Hilfe von beschleunigten Alterungstests. Bochen, Jerzy; Nowak, Henryk A. This article presents a technique for accelerated ageing tests for different plasters. Two models were developed for describing the durability.

The models describe changes in selected characteristics due to frost damage and leaching. The first model is based on changes in mass, the second on changes in strength. The models consider the main characteristics that influence durability, such as strength, porosity, permeability, adhesive tensil strength and aggressive environmental influences. Both models enable the durability of external plaster to be predicted. Abstract Copyright [], Wiley Periodicals, Inc. Fuer die Beschreibung der Dauerhaftigkeit wurden zwei Modelle entwickelt. Die Modelle beschreiben Veraenderungen ausgewaehlter Eigenschaften, die infolge von Frostschaeden und Auslaugung auftreten.

Das erste Modell basiert auf der Veraenderung der Masse und das zweite auf der Veraenderung der Festigkeit. In den Modellen werden die wesentlichen Eigenschaften beruecksichtigt, die die Dauerhaftigkeit beeinflussen, wie z. Festigkeit, Porositaet, Dichtigkeit, Haftzugfestigkeit und agressive Umwelteinwirkungen. Beide Modelle ermoeglichen die Prognose der Dauerhaftigkeit von Aussenputzen.

Based on the investigations of project VITE-BEMS, a computer-assisted method for commissioning and acceptance testing of complex digital building control systems is presented. Tests are classified as either open-loop or closed-loop tests. A test stand was constructed in which the control systems to be tested were connected to a building and facility simulation system in order to model the behaviour of the real facility for which the control system is intended. The models were adapted and optimized with a view to simplicity and easy convertibility.

Nach einer kritischen Betrachtung der Abnahmeprozesse in der gaengigen Praxis, werden hierfuer zunaechst Testprozeduren entwickelt. Diese Testprozeduren fuer die Inbetriebnahme und Abnahme von digitalen Regelungssysteme koennen unterteilt werden in Tests , bei denen das jeweilige Regelungssystem mit einer virtuellen heiz- und raumlufttechnischen Anlage in Wechselwirkung steht Closed-Loop- Tests und solchen, bei denen Regelfunktionen ohne eine direkte Rueckkopplung zur zu regelnden Anlage ueberprueft werden Open-Loop- Tests.

Durch diese unterschiedlichen Prozeduren wird eine systematische Ueberpruefung der Regelfunktionen, die vom Planer der jeweiligen Anlage spezifiziert und gefordert werden, ermoeglicht. Entsprechend den Anforderungen dieser Testprozeduren wird auf einem ebenfalls neu entwickelten Emulationsversuchsstand eine virtuelle Testumgebung aufgebaut, auf der die Prozeduren an den zu testenden Regelgeraeten ablaufen. In dieser Testumgebung wird das zu pruefende Regelungssystem an eine Anlagen- und Gebaeudesimulation angeschlossen.

Mit der Simulation wird das Verhalten der realen Anlage. They are also increased with pregnancy and with the use of estrogen medications such as oral contraceptives.

Aim: Patients with various disorders of gastric function were studied with radiolabeled test meals of different consistency to elaborate the effect of ingested media on gastric peristalsis and emptying. Methods: In 12 patients parameters of gastric function were intraindividually compared after ingestion of a semiliquid and a solid test meal.

In addition to the standard evaluation derived from time activity curves condensed images were established from two fixed time intervals early and late period. These images were used to evaluate the amplitude and frequency of gastric contractions using Fourier analysis. Results: As expected gastric emptying was influenced by the consistency of the test meal.

Mean emptying rates for the solid meal were significant lower than those for the semiliquid one p test meal. Within the course of the examination contraction amplitudes significantly increased p test meals. The frequency of gastric contractions remained unchanged. Conclusion: As shown by an intraindividual data comparison amplitude and frequency of gastric contractions seem to be independent of the consistency of ingested test meals whereas gastric emptying is significantly influenced by the administered media.

Semiliquid meals offer advantages with respect to the shorter examination time and simpler preparation and therefore may be preferred for routine use. Since amplitudes seem to vary within the observation period standardized acquisition protocols are recommended for the evaluation of this parameter.

Testing of media filled pipes and determination of the flaw depth by tomosynthesis; Mechanisierte Durchstrahlungspruefung von Rundschweissnaehten. Pruefung mediengefuellter Rohrleitungen und Tiefenlagenbestimmung durch Tomosynthese.

Ewert, U. A compact detection system was built for multi-angle inspection of pipes, consisting of a high-sensitivity radiometric line scanner and an ultrasonic manipulator. Improved flaw imaging quality is achieved with this system as compared to film radiography. Measurements have been carried out on site in a nuclear power plant and in a laboratory. Better flaw imaging quality was also achieved in the testing of water-filled pipes. Non-linear tomosynthesis was applied for processing and interpretation of measured data.

The system delivers considerably better images of planary materials inhomogeneitites, such as cracks and lack-of-bond defects. Bei der Inspektion von Rundschweissnaehten an Rohren mit ca. Ein signifikantes Ansteigen der Bildqualitaet wurde auch bei der Pruefung von wassergefuellten Rohren erzielt. Methoden der nicht-linearen Tomosynthese wurden fuer die Verarbeitung und Interpretation der gemessenen Projektionsdaten genutzt.

Das entwickelte System gestattet eine erhebliche Verbesserung der Anzeige von planaren Materialinhomogenitaeten z. Risse und Bindefehler. Post-operative pain relief in chronic pancreatitis CP is variable. Our objective was to determine clinical imaging or histopathologic predictor s of post-operative pain relief in CP patients undergoing the Whipple or Frey procedure. The post-operative histopathology was evaluated for severe fibrosis.

Clinical imaging and histopathologic features were evaluated as predictors of post-operative pain relief using univariable and multivariable regression analysis. A total of 60 patients age The proof is an application of simple hyperplane theorems Reliability analysis of digital radiography systems in the testing of real material defects; Zuverlaessikeitsanalyse von digitalen Radiographie-Systemen bei der Pruefung von realen Materialdefekten.

Nondestructive testing ndt systems are essential for areas in our lives, in which there is a high risk for failures that would induce high costs or even damage to people and the environment i. It is necessary to find and to characterise every defect in the material which might jeopardise the functionality of the tested part. But in the praxis the testing system will be used at their limits, i. Thus, there is a probability that critical defects might be overseen, which must be quantified. The evaluation is especially important for safety-relevant areas. The probability of detection POD characteristic is an objective number, which is widely used in these cases.

It is used to provide a statement about the tested ndt system. The POD can provide the statement whether the system is working well enough to be accepted to find the defects. The original POD method was developed for one-dimensional defects in thin parts used in the aircraft industry. In reality, the evaluation is a compromise between statistics and costs. On the one hand, the real testing situation should be evaluated for the later use.

On the other hand, the evaluation of real defects including the metallography and the comparison with the signals is a complex and expensive task. To find a coordinate system to compare the data is, therefore, an important prerequisite, before starting to evaluate. Therefore, this thesis will present a practical approach. The research community, as well, sees the POD of the real defects as a challenge.

The area of the NDT indication is one important fact which should be included. The thesis will introduce two new aspects to the calculation of the POD: 1. The area of the indication will be introduced by using a smoothing algorithm, which is based on the known Observer-POD. The Observer. Software testing and source code for the calculation of clearance values. The GRS research project was aimed to the test the appropriateness of the software package ''residual radioactivity'' RESRAD for the calculation of clearance values according to German and European regulations.

Una vez que se presenta se perpetua durante toda la vida si no se realiza tratamiento. Schuphan, I. Lehrstuhl fuer Biologie 5. One way to discover contaminations of soil in future is to use biological testing of soil extracts. For this purpose the baseline responses of the biological test systems have to be determined as a basis to distinguish between effects of natural soil components and those of contaminates. The use of extracts for testing requires references between the soil extract, the soil itself and the test system.

Starting values and the window of competence for testing are proposed. The starting value 1 SE is realized by equivalence of extract aliqouts of a defined soil amount gramm soil equivalent, g SE and the amount of test - cultur medium in g. The effect limits should be at least the double standard deviation of the blank extract without soil components.

If no relation can be found to the test - culture medium the so called window of competence has to be defined. This is necessary e. Die Verwendung von Extrakten fuer die. Frey procedure for the treatment of chronic pancreatitis associated with common bile duct stricture. In cases of biliary stricture, biliary derivation can be performed by choledochoduodenostomy, Roux-en-Y choledochojejunostomy or, more recently, reinsertion of the common bile duct CBD into the resection cavity. The objective of the present study was to evaluate the outcomes associated with each of these three types of biliary derivation.

We retrospectively analyzed demographic, CP-related, surgical and follow-up data for patients having undergone FP for CP with biliary derivation between and in our university medical center. The primary efficacy endpoint was the rate of CBD stricture recurrence.

The secondary endpoints were surgical parameters, postoperative complications, postoperative follow-up and the presence of risk factors for secondary CBD stricture.

Testing of corrosion resistant materials for evaporation plants for waste water from wet scrubbing of flue gas from power plants; Erprobung korrosionsbestaendiger Werkstoffe fuer Eindampfanlagen fuer Abwasser aus der Rauchgasreinigung von Grossfeuerungsanlagen.

Riedel, G. High alloyed superaustenitic steels and NiCrMo alloys are recommended in consequence of the results of extensive laboratory corrosion experiments under the strong corrosive conditions with up to g chloride content at temperatures up to 85 C. Because results of laboratory corrosion tests are only of limited relevance to the behaviour in practice, field tests were carried out with immersion of welded materials and of heat exchanger tubes under operating conditions of an evaporation plant for waste water from flue gas desulphurization of a coal-fired power plant.

Different kinds of high alloy superaustenitic steels and NiCrMo alloys were studied as TIG-welded specimens in immersion tests. Weil aber Ergebnisse von Laborpruefungen nur begrenzte Aussagefaehigkeit fuer das Verhalten unter Praxisbedingungen haben, wurden Feldversuche mit der Auslagerung geschweisster Werkstoffe und von Waermetauscherrohren unter Betriebsbedingungen einer Eindampfanlage fuer Abwasser aus der Rauchgasentschwefelung eines kohlebefeuerten Kraftwerks durchgefuehrt.

Grip strength in mice with joint inflammation: A rheumatology function test sensitive to pain and analgesia. Grip strength deficit is a measure of pain-induced functional disability in rheumatic disease. We tested whether this parameter and tactile allodynia, the standard pain measure in preclinical studies, show parallels in their response to analgesics and basic mechanisms. Mice with periarticular injections of complete Freund's adjuvant CFA in the ankles showed periarticular immune infiltration and synovial membrane alterations, together with pronounced grip strength deficits and tactile allodynia measured with von Frey hairs.

However, inflammation-induced tactile allodynia lasted longer than grip strength alterations, and therefore did not drive the functional deficits. Functional impairment was generally a more sensitive indicator of drug-induced analgesia than tactile allodynia, as drug doses that attenuated grip strength deficits showed little or no effect on von Frey thresholds. In conclusion, grip strength deficits are due to a distinct type of pain that reflects an important aspect of the human pain experience, and therefore merits further exploration in preclinical studies to improve the translation of new analgesics from bench to bedside.

In all sampling events the larvae of L. At the beginning of the reproductive period of L. The appearance of larvae coincides with the time of soybean planting in the field, thus the larvae feed on roots of soybean plants at the beginning of their development and the cycle from egg to adult of the two species was completed in one year.

Biological test methods for the ecotoxicological characterization of wastes. Final report; Biologische Testerverfahren zur oekotoxikologischen Charakterisierung von Abfaellen. The ecotoxicological characterization of waste is part of their assessment as hazardous or non-hazardous according to the European Waste List. Despite its transfer into national law in the waste list ordnance no methodological recommendations have been provided to cover the hazard criterion H14 ''ecotoxicity'' which was taken over from the legislation on dangerous substances.

In total, 67 laboratories from 15 countries participated in the ring test. It was performed with three representative waste types: an ash from an incineration plant mainly contaminated with heavy metals, a soil containing high concentrations of organic contaminants PAHs and a preserved wood waste contaminated with copper and other heavy metals. Samples were prepared by BAM e. Parallel to the biological testing the eluates and solid samples were chemically characterized. The basic test battery used in the ring test consisted of three aquatic Algae test , Daphnia acute test and Microtox test and three terrestrial earthworm acute and plant test with two species oat, rape tests.

In addition, data were submitted for ten additional tests five aquatic including a genotoxicity test and five terrestrial ones. Almost all tests were performed according to ISO guidelines, providing EC50 values as measurement of toxicity. Data evaluation was done following recent recommendations made by ISO and Environment Canada Besides a high number of reference test data, data sets were produced in the basic test battery and data sets in the additional tests. Only few data sets were not acceptable e. For example, in the case of the basic test. Evaluation, testing and further development of PV systems in Indonesia.

The Indonesian government initiated the World's biggest decentralised rural electrification programme with PV systems, the so-called 50 MW PV programme, which is to provide 10 million households with PV systems within the next decade. The report describes the financing, distribution strategies, organisation of maintenance work, and training. The focus will be on locally produced components, with cooperation of German organisations. Dort gibt es ungefaehr 23 Millionen Haushalte, die nicht an das nationale Stromnetz angeschlossen sind. Um diese zu ueberwinden, hat die indonesische Regierung das weltweit groesste dezentrale rurale Elektrifizierungsprogramm mit Photovoltaik, das sogenannte 50 MW PV-Programm, ins Leben gerufen.

Im Rahmen dieses Programmes sollen in den naechsten zehn Jahren eine Million Haushalte mit Photovoltaik versorgt werden. Welchen Einfluss dabei nicht-technische Aspekte, wie Finanzierungssysteme, Verbreitungsstrategien, Organisation von Wartungsarbeiten, Ausbildung der Programmakteure auf die Zufriedenheit der Nutzer mit den gelieferten Energiedienstleistungen hat und wie diese eine dauerhaften Betrieb und eine nachhaltige Verbreitung dieser Technologie foerdern koennen, war Gegenstand detaillierter Untersuchungen.

Grossen Wert legten wir auf Tests lokal produzierter Komponenten und Systeme, mit dem Ziel den beteiligten Firmen die Verbesserung der Qualitaet ihrer Produkte und Dienstleistungen zu ermoeglichen. Neben verschiedenen Projekterfolgen ist sicherlich erwaehnenswert, dass initiiert durch unsere Taetigkeiten, ein deutscher Ladereglerhersteller die Produktion seiner Regler in Zusammenarbeit mit einer indonesischen Firma ausweiten konnte.

The purpose of this study was to compare 2 types of reconstruction techniques: sternocleidomastoid SCM flap and superficial musculoaponeurotic system SMAS flap after partial parotidectomy PP for preventing Frey syndrome FS and concave facial depressed deformity. A total of 99 patients underwent PP for pleomorphic adenoma of the parotid gland.

The patients were divided in 2 groups according to the dimension of the tumor: tumors less than 3 cm group A, 47 patients and tumors greater than or equal to 3 cm group B, 52 patients. The study demonstrates a statistical difference P SCM flap with the subgroup of PP without reconstruction for tumors greater than 3 cm. The SCM is able to reduce the risk of the onset of both objective and subjective symptoms, whereas SMAS flap has a protective effect only in objective symptoms. Materials for the field test - students' attitudes to nuclear power stations.

Lars von Triers film. Afhandlingen analyserer de enkelte films stil, virkningsstrategi og betydningsdannelse The new standard ISO 'NDT of welded joints - Radiographic testing - Part 2: X- and gamma radiographic testing with digital detectors ''defines the testing practice for digital radiography of welds for the production and in-service inspection.

Furthermore the DIN ''In-service inspections of the components of the primary circuit of light water reactors - Part 7: Radiographic testing '' was published. The essential requirements are discussed. The new TomoWELD system can both perform measurements according to these standards as well as record tomographic cross-sectional images equivalent to metallographic sections , to determine image sizes.

Areas of application are chemical and nuclear facilities. It provides a fast testing of girth welds as compared to the use of film or imaging plates. In the mechanized planar tomography system, TomoCAR, was already introduced, with one could measure cross-sectional images. The new detector allows the choice of energy thresholds, and enables the reduction of the influence of scattered radiation on the radiographic images and the reconstructed cross-sectional images. An optimized irradiation geometry with a new manipulator design and a fast GPU-based reconstruction algorithm can be used to accelerate the reconstruction and to improve the reconstruction results.

The size and the shape of planar and voluminous irregularities can be determined. The concept and the first pictures will be presented. Contains mainly PowerPoint slides.

Uta Felten, Tanja Schwan Hg. The authors of the collected volume at hand attempt a reassessment of the work of the Mexican artist Frida Kahlo — in the context of current theoretical debates. They question how to best locate the artist within the contemporary Mexican and European art scene. The authors analyze the interplay between life, work, and reception of the artist by utilizing theoretical approaches from research on intermediality, gender, performance, and hybridity as well as inspirations from postcolonial theory.

The interest in the staging of the fragmented female body in the context of cultural hybridity ties the individual essays together. This is unfortunately not made clear in the title of the volume.

Development and test of a mobile environmental system for emission and ambient air measurement in the eastern part of Germany. Final report; Entwicklung und Erprobung eines mobilen Messsystems zur Emissions- und Immissionsmessung von Schadstoffen in den neuen Bundeslaendern; Abschlussbericht. A mobile environmental laboratory was developed and successfully tested. This system is used for the remote emissions and ambient air measurements. The key instrument of this laboratory is the Kayser-Threde double pendulum interferometer K, a field proven FT-IR system for remote emission and ambient air measurements.

In addition, the laboratory contains conventional ambient air sensors and a battery system for current source free usage. Basic scientific research was necessary for the development of appropriate analysis methods for quantitative detection of emissions from smoke stacks when doing remote sensing, as well as for ambient air measurements. The mobile laboratory was used in a number of measurement campaigns. The correspondence between the K remote sensing results with the measured values taken by conventional reference systems was good to excellent, in many cases considerably better than expected.

Hardware-in-the-Loop environment for testing and commissioning of space controllers; Hardware-in-the-Loop Umgebung zum Test und zur Inbetriebnahme von Raumreglern. The energy-efficient and optimal functioning of room controllers in terms of indoor air climates is influenced mainly by the control algorithm and the optimal adjustment of the parameters of controllers used in terms of space requirements.

In a hardware-in-the-loop HIL environment, room controllers can be examined in terms of the function under defined conditions, and different controllers can be evaluated comparatively. It is also possible to adjust the parameters of the controller before the commissioning. The HiL environment presented in the contribution under consideration consists of a model of the controlled system, a hardware coupler and a real controller to be tested. Among the spatial models, it can be selected from a plurality of different types of space which in turn can be assigned by means of different spatial parameters and environmental models.

These combinations enable a replication of a test scenario corresponding to the later application. The hardware coupler provides a selection of physical inputs and outputs as well as interfaces to different bus systems for example KNX, LON, EnOcean for connecting different types of controllers.

The construction and operation of a HIL test stand for space controller is presented based on first practical control tests. At this, the focus is on the suitability of this test environment for a variety of different controllers as well as development assistance and assistance for the adjustment of parameters.

Thoroughly tested. Field test to determine the real efficieny of heat pumps; Auf Herz und Nieren. Felduntersuchung zur realen Effizienz von Waermepumpen. Field tests of Fraunhofer ISE showed that the coefficients of performance of heat pumps vary widely, so that the use of calculated mean values should be reconsidered. The wide variation is due to faulty installation and operation but also to a change in the specific heat demand of buildings. New buildings have better thermal insulation and therefore more heat is consumed proportionally for freshwater heating, so the coefficient of performance will be lower.

Fabrication of ceramic components for fluidics with green machining and reaction binding of Al-containing precursor mixes - component design and testing.

Final report; Fertigung von keramischen Bauteilen fuer die Fluidtechnik mit Gruenbearbeitung und Reaktionsbinden von Al-haltigen Precursormischungen - Bauteilgestaltung und Erprobung. The Sauer-Danfoss project covered the testing of ceramic pistons and bushings in oil-hydraulic swash plate axial piston pumps. Both components move relative to each other while transmitting very high forces. This results in high component stresses and in high tribological loads of the contact surface. If the ceramic components can withstand both types of stress, the range of permissible operating parameters can be extended, especially the maximum speed as ceramics have a much lower specific mass than metals, which result in much lower inertial forces.

In conventional systems of steel piston and metal bushing, high speed and high temperatures will result in poor lubrication and cause freezing of the piston. This is not the case with ceramics because of their great hardness, heat resistance, and chemical inertness. Beide Bauteile die sogenannten Leitteile bewegen sich relativ zueinander und uebertragen dabei sehr hohe Betriebskraefte. Daraus resultieren nicht nur grosse Spannungen in den Teilen, sondern auch hohe tribologische Beanspruchungen in der Kontaktflaeche.

Wenn die keramischen Bauteile beiden Beanspruchungsarten gewachsen sind, dann ist eine Ausdehnung des Bereichs erlaubter Betriebsparameter moeglich. Insbesondere ist hier die maximale Drehzahl zu nennen, da aus der im Vergleich zu metallischen Werkstoffen sehr geringen spezifischen Masse von Keramik weitaus geringere Traegheitskraefte resultieren. Bei der konventionellen Werkstoffpaarung gehaerteter Stahlkolben-Messingbuchse besteht ausserdem bei hohen Drehzahlen und Temperaturen wegen der damit verbundenen schlechten Schmierung die Gefahr des Festfressens.

Diese ist bei keramischen Werkstoffen aufgrund der hohen Haerte, Waermebestaendigkeit und chemischen Inertheit nicht zu erwarten.

The aim of this study was to report on year long-term results of a randomized controlled trial comparing extended drainage procedure Frey and classical resectional procedure [pylorus-preserving pancreatoduodenectomy PD ] in patients with chronic pancreatitis.

Chronic pancreatitis is a common inflammatory disease with a prevalence of 10 to 30 cases per , inhabitants. It is characterized by the progressive conversion of pancreatic parenchyma to fibrous tissue. Different surgical procedures are used in treatment of persistent pain. The perioperative course of the randomized controlled trial and the 7 years follow-up have been previously published.

All participating patients were contacted with a standardized, validated questionnaire EORTC QLQ C30 to evaluate the long-term survival, quality-of-life pain, and exocrine and endocrine function. No correlation between endocrine or exocrine pancreatic function and pain was found, whereas continuous alcohol consumption was associated with poorer outcome regarding quality of life P treatment of chronic pancreatitis. Handheld mechanical nociceptive threshold testing in dairy cows - intra-individual variation, inter-observer agreement and variation over time.

To examine the use of handheld methodology to assess mechanical nociceptive threshold MNT on cows kept loose-housed. Prospective randomized partial cross-over experimental study. A one-factor test day design was used to evaluate MNT over time. One hundred and fifteen healthy, loose-housed Danish Holstein cattle.

We evaluated intra-individual variation, inter-observer agreement and variation over time of MNT using two handheld devices and two stimulation sites. Mechanical, ramped stimulations were performed with an algometer 6. We investigated the difference in precision [expressed as coefficient of variation CV ] between the combinations of devices and stimulation sites. The inter-observer agreement and the difference in MNT between test day 1, 3, 7, 10 and 24 were investigated for selected combinations. Data were analysed in mixed models and Bland-Altman as relevant.

Inattentional blindness and the von Restorff effect. Sometimes we fail to notice distinctive or unusual items inattentional blindness , while other times we remember distinctive items more than expected items the von Restorff effect. A three-factor framework is presented and tested in two experiments in an attempt to reconcile these seemingly contradictory phenomena.

Memory for different types of unexpected stimuli was tested after an easy or difficult Stroop color-naming task. Highly arousing taboo words were well remembered even when the difficult Stroop task limited attentional resources. As proposed in the three-factor framework, the arousing qualities of the stimuli, the attentional demands of the primary task, and the relevance of isolated features at encoding and retrieval combine to produce inattentional blindness and the von Restorff effect.

Advancement and testing of analysis techniques for the determination of the structural dynamic behavior of containment structures. Final report; Weiterentwicklung und Erprobung von Analysemethoden zur Bestimmung des strukturdynamischen Verhaltens von Containmentstukturen. Within the framework of project RS, analysis methods have been further developed and tested for the determination of the structural dynamic loading and the maximum load-bearing capacity of containment structures with a focus on the quantification of safety margins against failures due to loads resulting from selected internal and external hazards.

The analyses comprised a model containment structure of prestressed reinforced concrete under internal pressure loading until reaching failure pressure, an outer containment structure made of reinforced concrete under local impact loads that may occur during a targeted aircraft crash, and a steel containment under local peak loads from internal pressure and temperature loads due to core melt scenarios with a local hydrogen combustion.

Together with the cooperation partners, aspects of the global containment behaviour were considered based on the example of the Sandia model containment of prestressed concrete, which was loaded by rising internal pressure until failure. Complex analysis models were developed, calculating the behaviour of the prestressing tendons under consideration of the frictional contact with the cladding tubes. Compared with corresponding measurement values, the analysis results show that the stresses near the tensioning device and the deformation of the inner surface can be realistically modelled as a function of the internal pressure.

In the experiment, global structural failure of the containment model was caused by tendon rupture at about 3. With the developed analysis models of a generic structure of an outer reinforced concrete containment, simulations were carried out for various aircraft crash scenarios as contact problems with explicit impactor simulation.

For this. Decontamination of PAH polluted soils by fungi. Subproject: PAH degradation balance and testing of the extended laboratory process. The aim of the research project was first to select a fungus with a high potential for mineralization of polycyclic aromatic hydrocarbons PAH and a good ability to colonize different soils. The application of this fungus for a degradation of PAH in soil had to be tested.

In a screening of 57 white rot fungi the fungus Pleurotus sp. Florida fulfilled these requirements best. In pure culture it was able to metabolize and mineralize highly condensed ring PAH to a great extent. Therefore this capabilities of the fungus could not be proven in a joint medium-scale soil experiment 0.

Because of safety aspects only the low condensed less recalcitrant PAH could be applied in this experiment. Development of a fish test to determine endocrine effects in surface waters. Final report; Entwicklung eines Fischtests zur Erfassung von Stoffen mit endokrinen Wirkungen in Oberflaechengewaessern. Teilprojekt 3: Der neue Fischtest in der Gewaesserueberwachung durch eine Landesbehoerde. The aim of the presented study was to establish a method to detect estrogen-induced effects in the aquatic environment, basing on the determination of yolk-proteins in the blood of male or juvenile fish by gel electrophoresis SDS-PAGE.

The method is suitable for the use in routine testing of sewage treatment works STW effluents as well as monitoring of free living fish. In surface waters no estrogen-induced effects could be found, whereas effluents of some industrial STWs showed a weak estrogenic effect. Histology of normal gonadal development of the test fish is compared to the situation after exposure to endocrine disrupters and to the gonadal development of roach caught in the wild.

A method to detect effects on the gonadotropin mediated control of reproduction was tested within a monitoring programme. At certain locations a high degree of juvenile male perch showed gonadal hypertrophy pubertas praecox. It could be shown by chemical analysis that the effects on perch were highly correlated with the tributyl tin TBT burden of the sediment from the respective location.

Exposing small fish species to TBT in single compound studies confirmed the finding that TBT may act as an endocrine disrupter on vertebrates. Die Methode basiert auf der Identifikation von Dotterproteinen im Blut maennlicher oder juveniler Fische mittels Gelelektrophorese und ist sowohl zum Einsatz in Monitoringprogrammen freilebender Fische als auch fuer die Routine der Abwasseruntersuchung nach DIN geeignet.

Fractal geometry is used in diverse research areas, being an useful tool in describing the mechanical behaviour of natural and man-made structures. In this paper, the structural behaviour of a von Koch cantilever beam is analyzed in the small deformations regime.

Analytical recursive formulae for the strain energy scaling are derived, which have been found in good agreement with numerical simulations. Energy considerations suggest a peculiar scaling for the beam rigidity in order to prevent compliance divergence. The results are then extended to evaluate the stiffness matrix of a von Koch beam.

Increase of the efficiency of heat pumps by partial defrosting of evaporator during the heating operation; Effizienzsteigerung von Waermepumpen durch partielle Verdampferabtauung waehrend des Heizbetriebs.

At low ambient temperatures, the evaporation temperature in air-to-water heat pumps may fall below the freezing point of water; the water content of the air will then form a frost layer on the outside of the heat exchanger. This increases the pressure drop on the air side and reduces the heat transfer capacity, i.

Finally, if operation in these conditions continues, the evaporator may freeze in parts or even wholly. In order to prevent failure and damage, regular defrosting will be necessary. One common method is the reversal of the coolant flow by leading hot gas into the evaporator from the condenser. Apart from the loss of efficiency, this will incur material problems and, in some cases, loss of comfort. Partial thawing attempts to reduce or avoid flow reversal by deactivating evaporator lines one at a time in order to enable thawing by air flow, while the other parts of the evaporator will continue operation.

This is made possible by a special type of valve that combines expansion and distribution for selective operation of individual evaporator tubes. Using a mathematical model, details of the method are presented and discussed. Experiments on air-to-air heat pumps show that the whole system can be defrosted this way in standard operating conditions with air temperatures above freezing point, so that flow reversal will not be necessary.

A Murray— von Neumann algebra is the algebra of operators affiliated with a finite von Neumann algebra. In this article, we first present a brief introduction to the theory of derivations of operator algebras from both the physical and mathematical points of view. We then describe our recent work on derivations of Murray— von Neumann algebras. In particular, we prove that the only derivation that maps a Murray— von Neumann algebra associated with a factor of type II1 into that factor is 0.

A note on derivations of Murray- von Neumann algebras. A Murray- von Neumann algebra is the algebra of operators affiliated with a finite von Neumann algebra. We then describe our recent work on derivations of Murray- von Neumann algebras. We show that the "extended derivations" of a Murray- von Neumann algebra, those that map the associated finite von Neumann algebra into itself, are inner. In particular, we prove that the only derivation that maps a Murray- von Neumann algebra associated with a factor of type II1 into that factor is 0.

Those results are extensions of Singer's seminal result answering a question of Kaplansky, as applied to von Neumann algebras: The algebra may be noncommutative and may even contain unbounded elements.

The Molecular Genetics of von Willebrand Disease. Incomplete penetrance and variable expression due to genetic and environmental factors contribute to its complexity. Some vWF gene mutations are associated with the affected vWF biosynthesis and multimerization, whereas others are associated with increased clearance and functional impairment. Moreover, in addition to a particular mutation, type O blood may result in the more severe phenotype. The present review aimed to provide a summary of the current literature on the molecular genetics of vWD.

The molecular genetics of von Willebrand disease. None declared. An orthonormal basis of modified coherent states is constructed. Each member of the basis is an infinite sum of coherent states on a von Neumann lattice. A single state is assigned to each unit cell of area h Planck constant in the phase plane.

The uncertainties of the coordinate x and the square of the momentum p 2 for these states are shown to be similar to those for the usual coherent states. Expansions in the newly established set are discussed and it is shown that any function in the kq-representation can be written as a sum of two fixed kq-functions. Approximate commuting operators for x and p 2 are defined on a lattice in phase plane according to von Neumann's prescription. Inspired by Volta's pile he proposed the first theory of water electrolysis, which was published in in Rome.

This report for the Swiss Federal Office of Energy SFOE is the introductory report to a series of five reports dealing with increasing the overall efficiency of photovoltaic PV installations by also using the heat collected by the dark-coloured PV panels. This introductory report summarises the findings of the project.

The work reported on addresses open questions on the use of the heat and its optimal use. A mathematical model for the calculation of the dynamic gain is described. Measured data from reports 1 and 2 are compared with the simulation results. In the yield atlas report 4 the heat gain expected is subdivided into classes of temperature and presented for three locations in different Swiss climatic regions. In report 5 it is shown with the help of the yield-atlas how the degree of utilisation can be estimated. Two promising applications domestic hot water preheating for a hotel in Lugano and seasonal ground heat storage for a Minergie low energy consumption house in Davos are selected for detailed investigation using the new numerical model.

Erhitzen von Amiloridhydrochlorid Chancen und Gefahren von Global-Marketing-Konzepten. Marketing, A bicategorical approach to Morita equivalence for von Neumann algebras. We relate Morita equivalence for von Neumann algebras to the ''Connes fusion'' tensor product between correspondences. In the purely algebraic setting, it is well known that rings are Morita equivalent if they are equivalent objects in a bicategory whose 1-cells are bimodules. We present a similar result for von Neumann algebras. We show that von Neumann algebras form a bicategory, having Connes's correspondences as 1-morphisms, and bounded intertwiners as 2-morphisms.

Further, we prove that two von Neumann algebras are Morita equivalent iff they are equivalent objects in the bicategory. The proofs make extensive use of the Tomita-Takesaki modular theory.

Erfahrungen an der Schnittstelle von Medienarbeit und Praxisforschung. Von Recklinghausen's disease belongs to a group of neurocutaneous syndromes and is characterised by skin, nerve and bone abnormalities. We present a case of von Recklinghausen's disease and precocious puberty in 7-year-old boy. At the age of 7 first signs of precocious puberty appeared pubic hair P3 and enlargement of the testes 15 ml and penis.

Laboratory measurements included: LH 7. The MRI of the brain showed a tumour of the suprasellar region with compression of pituitary stalk. True precocious puberty was diagnosed. Treatment with Diphereline was introduced. At present the boy is 9 years old and has been treated with Diphereline for 16 months. The volume of the testicles has decreased to 7 ml and loss of pubic hair was noted. The MRI does not show any progression in tumour growth. The authors would like to underline the need of close observation of children with von Reclinghausen disease with regard to possibility of uncovering true precocious puberty which is critical for rapid diagnosis and introduction of correct treatment.

Development of plans for retrofitting Russian housing, taking into account European competences for increasing its energy efficiency; Entwicklung von Planungs- und Sanierungskonzepten fuer den russischen Wohnungsbau. Hierzu wurden die klimatischen Bedingungen Russlands am Beispiel der russischen Metropole Sankt Petersburg in die Berechnungen integriert. Die Datenanalyse des Bestandsgebaeudes eroeffnet eine grosse Bandbreite an Moeglichkeiten zur Erhoehung der Energieeffizienz.

So wird unter anderem im Zuge der Berechnungen festgestellt, dass durch relativ kostenguenstige Massnahmen zur Verbesserung des Waermeschutzes eine bedeutende Verringerung des Endenergiebedarfs erreicht werden kann. Es werden weiterhin moegliche Sanierungsvarianten unter Einbeziehung verschiedener Materialien und Heizungsanlagen vorgestellt. Die Ergebnisse machen deutlich, dass die Zukunft russischer Wohnhaeuser wie der hier dargestellten Typenserie alles andere als aussichtslos ist, wie oft vermutet wird.

Sie koennen im Gegenteil durchaus als komfortabler und funktionaler Wohnraum dienen. Auch die Verwendung regenerativer Energiequellen wie der Solarenergie ist unter den Bedingungen einer noerdlich gelegenen Stadt wie Sankt Petersburg realisierbar. Die durchgefuehrten Berechnungen zeigen, dass eine Sanierung der russischen Wohnbauten der ersten Periode des industriellen Bauens durchaus lohnenswert sein kann, insbesondere wenn man die Entwicklung der Energiepreise betrachtet.

In addition, the efforts of the European and German legislators are analyzed in order to reduce the particulate matter pollution.

In addition, legal protection against the exceeding of limits for particulate matter is critically appreciated. Darueber hinaus werden die Bemuehungen des europaeischen und deutschen Gesetzgebers analysiert, um die Feinstaubbelastung zu senken. Zudem wird der Rechtsschutz gegen die Ueberschreitung von Feinstaubgrenzwerten kritisch gewuerdigt.

A Metabiography of Alexander von Humboldt. Full Text Available Article in English. The author's recently published monograph on Alexander von Humboldt describes the multiple images of this great cultural icon. The book is a metabiographical study that shows how from the middle of the nineteenth century to the present day Humboldt has served as a nucleus of crystallisation for a variety of successive socio-political ideologies, each producing its own distinctive representation of him.

The historiographical implications of this biographical diversity are profound and support current attempts to understand historical scholarship in terms of memory cultures.

Guy von Dardel, a well-known figure at CERN and in the international particle physics community, passed away on 28 August. Guy von Dardel came to CERN when it was founded in and was a full-time staff member until , performing several experiments and working on technical developments. Called to Lund University in , he became professor there in and director of the 1. Then, in the early s, he involved the Lund group in a series of experiments at the Intersecting Storage Rings ISR , where he measured the production of various types of particles. In particular, he participated in a series of experiments that observed the production of a high abundance of particles with large transverse momenta.

This required an explanation Translational Medicine Advances in von Willebrand Disease. Following the recognition of von Willebrand disease VWD in and the cloning of the gene for von Willebrand factor VWF in , significant advances have been made in our fundamental knowledge of both the disease and the protein. Some of this new knowledge has also begun to impact the clinical management of VWD. First, the progressive increase in our understanding of the molecular genetic basis of VWD has resulted in rational applications of molecular testing to complement the current range of phenotypic tests for VWD.

These molecular genetic strategies are most effectively directed at the prenatal diagnosis of type 3 VWD and confirmatory testing for types 2B and 2N disease. In contrast, the use of molecular testing to clarify the diagnosis of type 1 VWD is of marginal benefit, at best. In terms of VWD therapies, a new recombinant VWF concentrate has recently completed successful clinical trials and is now awaiting more widespread application. There have even been some pre-clinical successes with VWF gene transfer although the clinical rationale for this therapeutic strategy needs careful consideration.

Much more remains to be learnt about the biology of VWF and further translational advances for the enhancement of VWD care will inevitably be realized.

Hydrological tracer techniques are a means of making statements on the direction and speed of underground water. One of the simpler tasks is to find out whether there is hydrological communication between two given points.

This requires a determination of the direction of flow, which places less exacting demands on the properties of the tracer than does the task of determining the flow velocity of underground water. Tracer methods can serve to infer from flow velocity the distance flow velocity, which is defined as the ratio between the distance between two points located in flow direction and the actual time it takes water to flow from one to the other.

Der einfachere Fall liegt vor, wenn festgestellt werden soll, ob zwischen zwei Punkten eine hydrologische Verbindung besteht. Bei dieser Fliessrichtungsbestimmung sind die Forderungen an die Eigenschaften der einzusetzenden Tracer geringer als bei der Bestimmung der Geschwindigkeit des unterirdischen Wassers. Von den Geschwindigkeiten des unterirdischen Wassers ist die Abstands- Fliess geschwindigkeit, die definiert ist durch das Verhaeltnis aus dem Abstand und der wahren Fliesszeit zwischen zwei in Bewegungsrichtung gelegenen Punkten, durch Tracermethoden zu bestimmen.

Abstract During July a meeting between two men takes place, which seems to have been extraneous, but turns out to be a significant historical incident.

The prospective young scientist expects help and references from famous Alexander von Humboldt. Unfortunately this is going to be the only meeting between the two scientists even though the two Prussians have more in common than their passion for the natural sciences.

Clarifying the link between von Neumann and thermodynamic entropies. A Shenker's paper initiated a debate about its link with the entropy of phenomenological thermodynamics. Referring to Gibbs's and von Neumann's founding texts, we replace von Neumann's contribution in its historical context, after Gibbs's treatise and before the creation of the information entropy concept, which places boundaries into the debate. Reexamining von Neumann's reasoning, we stress that the part of his reasoning implied in the debate mainly uses thermodynamics, not quantum mechanics, and identify two implicit postulates.

We thoroughly examine Shenker's and ensuing papers, insisting upon the presence of open thermodynamical subsystems, imposing us the use of the chemical potential concept. We briefly mention Landau's approach to the quantum entropy. On the whole, it is shown that von Neumann's viewpoint is right, and why Shenker's claim that von Neumann entropy "is not the quantum-mechanical correlate of thermodynamic entropy" can't be retained.

Richter, W. Dresden Germany. When redeveloping buildings it is common to use window constructions with air-tight rabbets which obviate the inflow of fresh air almost entirely. This leads to the well-known structural-physics and hygienic consequences. As an added effect, the distinctly enhanced thermal insulation results in changes in dynamic heat loss. The paper focuses on the issues of how to safeguard the inflow of fresh air, and the heating capacity of radiators.

Of von Willebrand factor and platelets. Hemostasis and pathological thrombus formation are dynamic processes that require multiple adhesive receptor-ligand interactions, with blood platelets at the heart of such events. This review will recapitulate our current knowledge on the subject from the rheological aspect to the spatio-temporal development of thrombus formation. Additionally, we will review the growing body of evidence gathered from the recent development of pathological mouse models suggesting that VWF binding to GPIb-IX-V is a promising target in arterial and venous pathological thrombosis.

Finally, the pathological aspects of VWF and its impact on platelets will be addressed. Ex-ante Evaluation von Investitionsalternativen.

We study Jauch-Piron states and two-valued measures on von Neumann algebra. Moreover, we show that this result holds for type I factor indenpendently on the set-theoretical axiomatics.

As a consequence we obtain a lucid characterization of pure Jauch-Piron states on von Neumann algebras acting on a Hilbert space with real-nonmeasurable dimension this can be viewed as a generalization of the paper. We also characterize the von Neumann algebras whose logic of projections is Jauch-Piron. Finally, we prove that every two-valued measure on the projection logic of A, where A contains no type I 2 central portion, has to be concentrated at an abelian direct summand of A. Jalaka ja S.

There are several sampling methods for hydroperoxides none of which is particularly reliable. The authors therefore tested three new methods in order to optimize hydroperoxide sampling and, using the optimized sampling procedure, to investigate the water vapour dependence of hydroperoxide formation during ozonolysis of alkenes. Daher wurden in dieser Arbeit drei Verfahren getestet, um die Probenahme von Hydroperoxiden zu optimieren und mit dem entsprechenden Verfahren die Wasserdampfabhaengigkeit der Bildung von Hydroperoxiden bei der Ozonolyse von Alkenen zu untersuchen.

Von Neumann's impossibility proof: Mathematics in the service of rhetorics.

According to what has become a standard history of quantum mechanics, in von Neumann persuaded the physics community that hidden variables are impossible as a matter of principle, after which leading proponents of the Copenhagen interpretation put the situation to good use by arguing that the completeness of quantum mechanics was undeniable.

This state of affairs lasted, so the story continues, until Bell in exposed von Neumann's proof as obviously wrong. The realization that von Neumann's proof was fallacious then rehabilitated hidden variables and made serious foundational research possible again. It is often added in recent accounts that von Neumann's error had been spotted almost immediately by Grete Hermann, but that her discovery was of no effect due to the dominant Copenhagen Zeitgeist.

We shall attempt to tell a story that is more historically accurate and less ideologically charged. Most importantly, von Neumann never claimed to have shown the impossibility of hidden variables tout court, but argued that hidden-variable theories must possess a structure that deviates fundamentally from that of quantum mechanics. Both Hermann and Bell appear to have missed this point; moreover, both raised unjustified technical objections to the proof. Von Neumann's argument was basically that hidden-variables schemes must violate the ;quantum principle; that physical quantities are to be represented by operators in a Hilbert space.

As a consequence, hidden-variables schemes, though possible in principle, necessarily exhibit a certain kind of contextuality. As we shall illustrate, early reactions to Bohm's theory are in agreement with this account. Leading physicists pointed out that Bohm's theory has the strange feature that pre-existing particle properties do not generally reveal themselves in measurements, in accordance with von Neumann's result.

They did not conclude that the ;impossible was done; and that von Neumann had been shown wrong.

Lifescience Database Archive English. Erste Erfahrungen. The RCP method was designed as a residue-optimised alternative to the thermally optimised grate firing of residual wastes. Its technical realisation and development to market maturity took no more than 5 years. In the first process stage the waste is converted to high-carbon pyrolysis charcoal and high-rank gas in the absence of oxygen. In the second stage these substances are oxidised by addition of oxygen.

The resulting temperature causes the non-combustible constituents of the slag to melt. In a third, optional, stage this molten slag can be liberated of heavy metals to such an extent that it can subsequently be used directly as additive for grinding. Further exhaust gas treatment is facilitated by the use of a circulatory fluidised-bed secondary combustion chamber. Despite the reduced flue gas volume and resultant higher pollutant concentrations in the crude gas, overall emissions are lower than in conventional plants. In nur fuenf Jahren wurde das Verfahren technisch umgesetzt und zur Marktreife entwickelt.

In einer ersten Stufe des Verfahrens wird der Abfall unter Luftabschluss in einen kohlenstoffreichen Pyrolysekoks und eine heizwertreiches Gas umgesetzt. Im zweiten Schritt werden diese Stoffe unter Zugabe von Sauerstoff oxidiert. Dabei treten Temperaturen auf, bei denen die nichtbrennbaren Bestandteile der Schlacke schmelzen.

Optional wird diese Schmelzschlacke in einem dritten Schritt derart von Schwer- Metallen befreit, dass sie anschliessend direkt als Zement-Zumahlstoff eingesetzt werden kann.
