    In the Introduction the reader is referred back to the academic ceremonials held after Theodore von Kármán's death in Aachen in May 1963. His work as the first director of the Aerodynamisches Institut (Institute of Aerodynamics) of the RWTH Aachen University of Technology from 1913 on and his initiative to re-establish international cooperation after World War I, resulting in the International Union of Theoretical and Applied Mechanics (IUTAM), are commented on. The following chapter describes von Kármán's relation to his former teacher Ludwig Prandtl. Some of von Kármán's scientific contributions during his time in Aachen are briefly reviewed. Thereafter, his first contacts to the California Institute of Technology are covered. Finally, the scientific and political circumstances, which led to von Kármán's decision to leave Germany in the early thirties, are elucidated in some detail. The English translation of the titles of the Aachen papers is given in Appendix I.

    In the early 19th century coal mining in the region of Aachen (Prussian Rhine Province) developed to an industrial scale within few decades production was mechanised and new types of industrial organization emerged that allowed for concentration on production and economies of scale. The region...... hosted two mining areas (the Wurm area and the Inde area) showing rather different patterns of development; while the industry on the Inde was al-ready concentrated at the turn of the century, and industrial modes of production emerged earlier, the industry on the Wurm developed slowly more slowly...

    Silicified fossil woods from the Late Cretaceous (Santonian) Aachen Formation of northeast Belgium, southernmost Netherlands and adjacent Germany were investigated. Gymnosperms dominate this assemblage: Taxodioxylon gypsaceum, T. cf. gypsaceum, T. cf. albertense (all Taxodiaceae), Dammaroxylon aachenense sp. nov. (Araucariaceae), Pinuxylon sp. (Pinaceae), and Scalaroxylon sp. (Cycad or Cycadeoid). Angiosperms are minor constituents: Nyssoxylon sp. (Nyssaceae?, Cornaceae?), Mastixioxylon symplocoides sp. nov. (Mastixiaceae?, Symplocaceae?), Plataninium decipiens (Platanaceae) and Paraphyllanthoxylon cf. marylandense (Anacardiaceae?, Burseraceae?, Lauraceae?).The composition of this assemblage and the anatomy of the woods indicate a seasonal and humid warm-temperate to subtropical climate.

Fordemonstration purposes, this measurement system was integrated into an off-the-shelf office chair (so-called “Aachen SmartChair”.Whereas in usual clinical applications adhesive, conductively-coupled electrodes have to be attached to the skin, the described system is able to measure an ECG without direct skin contact through the cloth. A wireless communication module was integrated for transmitting theECG data to a PC or to an ICU patient monitor. For system validation, a classical ECG with conductive electrodes and an oxygensaturation signal (SpO2 were obtained simultaneously. Finally, system-specific problems of the presented device are discussed.

  2. Measurements and Design Calculations for a Deep Coaxial Borehole Heat Exchanger in Aachen, Germany

    Full Text Available This study aims at evaluating the feasibility of an installation for space heating and cooling the building of the university in the center of the city Aachen, Germany, with a 2500 m deep coaxial borehole heat exchanger (BHE. Direct heating the building in winter requires temperatures of 40°C. In summer, cooling the university building uses a climatic control adsorption unit, which requires a temperature of minimum 55°C. The drilled rocks of the 2500 m deep borehole have extremely low permeabilities and porosities less than 1%. Their thermal conductivity varies between 2.2 W/(m·K and 8.9 W/(m·K. The high values are related to the quartzite sandstones. The maximum temperature in the borehole is 85°C at 2500 m depth, which corresponds to a mean specific heat flow of 85 mW/m2–90 mW/m2. Results indicate that for a short period, the borehole may deliver the required temperature. But after a 20-year period of operation, temperatures are too low to drive the adsorption unit for cooling. In winter, however, the borehole heat exchanger may still supply the building with sufficient heat, with temperatures varying between 25 and 55°C and a circulation flow rate of 10 m3/h at maximum.

    Schreiber, Jürgen; Lohmeier, Jens

    2010-01-01

    The article deals with the question of medicine in the time of the Nazi regime in Germany. It focuses on the question how the media in the "Third Reich" took up the subject "medicine" in general and which aspects were notably mentioned. The footing of this research is the "Westdeutscher Beobachter" and its local edition for the region and the city of Aachen. It was a newspaper published by the regional division of the NSDAP, hence a direct repetition of the Nazi ideology can be expected. During the research it became clear that medicine was not an important subject of propaganda in this newspaper. Only a few articles were about classic Nazi medical topics like "Erbgesundheit" (racial hygiene) and even less about naturopathy. The frequency of articles containing medical issues was very inconsistent, but only in 1934 there was a mentionable number of articles mostly concerning "Erbgesundheit". In this year the racial hygiene poured in law. The main consequence was the forced sterilization of over 300,000 people. Furthermore the topic "medicine" in general seems to be a marginal factor. More popular topics like economic or foreign policy dominated the report of the "Westdeutscher Beobachter". It seems to be that the emphasis was deliberately not laid on the matter "medicine" especially eugenics--which was one of the main components of the Nazi ideology--because the regime didn't want it to become a public interest.

    Full Text Available Understanding the role of structure and social aspects regarding heat stress of people in urban areas requires an interdisciplinary scientific approach that connects methods from both natural sciences and social sciences. In this study, we combine three approaches to provide an interdisciplinary analysis of the structure and social components of heat stress in the city of Aachen, Germany. First, we assess the overall spatial structure of the urban heat island using spatially distributed measurements from mobile air temperature recordings on public transport units combined with spatially distributed geo-statistical data. The results indicate that the time of day matters: During the afternoon, areas with a relative low building density, like the industrial area northeast of the inner city, are the warmest, while surfaces in high-building-density areas like the inner city heat up faster during the evening. Second, we combine these measurements with place-based survey data collected in 2010 from residents aged 50 to 92 regarding their individual housing conditions, medical history and social integration to examine the match among heat-based stress of older residents, social conditions and elevated temperatures in their residential quarter. We identify disadvantaged areas for specific already-disadvantaged demographic groups in the city, pointing to a cumulation of inequalities, including heat stress among the most vulnerable. Third, we compare data of biometeorological measurements on urban public squares during the afternoon with results of the micrometeorological model ENVI-met to examine the spatial variability of the inner-city heat load. We complement the modelling results with on-site interviews to evaluate people’s heat perception at the same public places. A simulation shows that additional vegetation would increase thermal comfort at these public places, whereby the heat load assessed using the predicted mean vote (PMV value would

    Full Text Available Together you will get there. A graduation article on the Skejby halfway house: a house where delinquents and students live togetherThe Skejby house is unique and produces remarkable results. The recidivism percentage among its’ delinquent inhabitants is over 20% lower than in the halfway houses where only prisoners reside. The aim of Skejby is to ease the transition between imprisonment and reentry in society. The experiment, in which students and prisoners live together, originates from the idea that behavioral transformation is realized most effectively within a socially engaged group. The principal of collective responsibility is dominant in Skejby, resulting in a feeling of belonging to a group among the delinquents. In this group, the students serve as prosocial role models. Consequently, the standards and values that are picked up in prison are reshaped into much needed skills that are required for living a “regular” life in society. In contrast to the reintegration program in Skejby, the Dutch reintegration program mainly consists of one-to-one consultations between the delinquent and the probation officer. The reintegration thus does not take place in a group to which the delinquent can relate, while it is precisely this unique communal feeling of belonging that induces behavioral change in the prisoners. SAMENVATTING Samen kom je er wel. Een afstudeerartikel over het Skejby halfway house: een huis waar delinquenten en studenten onder één dak wonenHet Skejby house is uniek in zijn soort en boekt opmerkelijke resultaten: het recidivepercentage ligt ruim 20% lager dan bij halfway huizen waar alleen delinquenten wonen. Skejby heeft als doel om de overgang tussen gevangenis en samenleving zo klein mogelijk te maken. Het experiment, waarbij studenten en delinquenten samen wonen, komt voort uit het idee dat gedragsverandering het best bewerkstelligt wordt binnen een sociaal verbonden groep.

This study presents our first experience with teaching microsurgery to medical students by means of highdefinition stereo video monitoring. Material and methods: A plastic model created for ear inspection with a handheld otoscope was modified with an exchangeable membrane resembling an eardrum plus a model of the human cochlea. We attached a 1280×1024 HD stereo camera to an operating microscope, whose images were processed online by a PC workstation. The live image was displayed by two LCD projectors @ 1280×720 pixels on a 1,25m rear-projection screen by polarized filters. Each medical student was asked to perform standard otosurgical procedures (paracentesis and insertion of grommets; insertion of a cochlear implant electrode) being guided by the HD stereoscopic video image. Results: Students quickly adopted this method of training, as all attendants shared the same high-definition stereoscopic image. The learning process of coordinating hand movement with visual feedback was regarded being challenging as well as instructive by all students. Watching the same image facilitated valuable feedback from the audience for each student performing his tasks. All students noted that this course made them feel more confident in their manual skills and that they would consider a career in a microsurgical specialty. Conclusion: High definition stereoscopy provides an easy access to microsurgical techniques for undergraduate medical students. This access not only bears the potential to compress the learning curve for junior doctors during their clinical training but also helps to attract medical students to a career in a microsurgical specialty.

    Fall incidents are a major problem for patients and healthcare. The "Aachen Fall Prevention App" (AFPA) represents the first mobile Health (mHealth) application (app) empowering older patients (persons 50+ years) to self-assess and monitor their individual fall risk. Self-assessment is based on the "Aachen Fall Prevention Scale," which consists of three steps. First, patients answer ten standardized yes-no questions (positive criterion ≥ 5 "Yes" responses). Second, a ten-second test of free standing without compensatory movement is performed (positive criterion: compensatory movement). Finally, during the third step, patients rate their subjective fall risk on a 10-point Likert scale, based on the results of steps one and two. The purpose of this app is (1) to offer a low-threshold service through which individuals can independently monitor their individual fall risk and (2) to collect data about how a patient-centered mHealth app for fall risk assessment is used in the field. The results represent the first year of an ongoing field study. From December 2015 to December 2016, 197 persons downloaded the AFPA (iOS ™ and Android ™ ; free of charge). N  = 111 of these persons voluntarily shared their data and thereby participated in the field study. Data from a final number of n  = 79 persons were analyzed due to exclusion criteria (age, missing objective fall risk, missing self-assessment). The objective fall risk and the self-assessed subjective risk measured by the AFPA showed a significant positive relationship. The "Aachen Fall Prevention App" (AFPA) is an mHealth app released for iOS and Android. This field study revealed the AFPA as a promising tool to raise older adults' awareness of their individual fall risk by means of a low-threshold patient-driven fall risk assessment tool.

    Reconstructing paleo-landscapes in urban areas is always a special challenge since the research area often witnessed constant human impact over long time periods. Dense building development is a major difficulty, particularly in regard to accessibility to in-situ soils and archaeological findings. It is therefore necessary to use data from various sources and combine methods from different fields to gain a detailed picture of the former topography. The area, which is occupied by the city of Aachen today, looks back on a long history of human influence. Traces of human activity can be dated back to Neolithic time. The first architectural structures and the first road network were built by the Romans about 2000 years ago. From then on, the area of Aachen was more or less continuously inhabited forming today's city. This long history is represented by archaeological findings throughout the city. Several meters of settlement deposits, covering different eras, are present in many locations. Therefore, it can be assumed that the modern topography significantly differs from the pre-roman topography. The main objective of this project is a reconstruction of the paleo-topography of Aachen in order to gain new insights on the spatial preconditions that the first settlers found. Moreover, further attention is given to the question whether and to what extent a paleo-DEM can help to clarify specific open archaeological and historical questions. The main database for the reconstruction are the archaeological excavation reports of the past 150 years, provided by municipal and regional archives. After analyzing these written accounts, we linked this information to drill data, provided by the Geological Service of North Rhine-Westphalia. Together with additional sources like geological and hydrological maps, we generated a GIS-based terrain model. The result is a high-resolution terrain model, representing the undisturbed pre-roman topography of the inner city of Aachen without any

    The goal of the Frejus experiment is the measurement of the nucleon lifetime, using a 900 ton fine grain iron calorimeter. The background due to the interaction of atmospheric (anti) neutrinos is studied with data from a spark chamber experiment in the CERN PS low energy neutrino beam (Aachen-Padova collaboration). The analysis of the data yields a preliminary estimate of the (anti) neutrino background which is expected for nucleon decays into a charged lepton. An important feature of the (anti) neutrino background is that one half of the background come from events where a secondary re-interaction vertex is taken as the main vertex [fr

    Full Text Available Spatial micro-scale variability of particle mass concentrations is an important criterion for urban air quality assessment. In this study we present results from detailed spatio-temporal measurements in the urban roughness layer along with a survey to determine perceptions of citizens regarding air quality in an inner city park in Aachen, Germany. Particles were sampled with two different approaches in February, May, July and September 2014 using an optical particle counter at six fixed measurement locations, representing different degrees of outdoor particle exposure that can be experienced by a pedestrian walking in an intra-urban recreational area. A simulation of aerosol emissions induced by road traffic was conducted using the German reference dispersion model Austal2000. The mobile measurements revealed unexpected details in the distribution of urban particles with highest mean concentrations of PM(1;10$\\text{PM}_{(1;10}$ inside the green area 100 m away from bus routes (arithmetic mean: 22.5 μg m−3 and 18.9 μg m−3; geometric mean: 9.3 μg m−3 and 6.5 μg m−3, whereas measurement sites in close proximity to traffic lines showed far lower mean values (arithmetic mean: 7.5 μg m−3 and 8.7 μg m−3; geometric mean: 5.8 μg m−3 and 6.5 μg m−3. Concerning simulation results, motor traffic is still proved to be an important aerosol source in the area, although the corresponding concentrations declined rapidly as the distances to the line sources increased. Further analysis leads to the assumption that particularly coarse particles were emitted through diffuse sources e.g. on the ability of surfaces to release particles by resuspension which were dominantly apparent in measured PM(1;10$\\text{PM}_{(1;10}$ and PM(0.25;10$\\text{PM}_{(0.25;10}$ data. The contribution of diffuse particle sources and urban background transport to local PM(0.25;10$\\text{PM}_{(0.25;10}$ concentrations inside the

    Full Text Available Lecturing on nature conservancy at Amsterdam and Stellenbosch offered the possibility to investigate if biology students in different countries and cultures have different views on nature and nature conservation. The results of a short questionnaire show a similar broad attitude towards nature and nature conservation in both university student groups. They all want action with respect to global problems (global warming/climate change. But next to that there are also typical national problems like Dutch fisheries discussions and South African eradication of alien species and more attention for water and soil pollution. Moreover, there was a shared interest in more social aspects of nature conservation (education, awareness/consciousness, population growth. A major bias is that the answers express the views of well educated, white people. Extension to young people of other cultural background is needed. So feel free to ask for the questionnaire.

    Full Text Available Hensikten med studiet var å belyse hvordan videodokumentasjon av praktiske handlinger i sykepleie kunne brukes som evalueringordning av studenter. Artikkelen tar utgangspunkt i et forskningsprosjekt for utprøving av nye lærings og evalueringsformer i bachelorutdanningen i sykepleie, der 13 studentgrupper gjennomførte sin praktiske eksamen ved innlevering av video av 16 utvalgte øvelser. Tradisjonell praktisk eksamen i samme studentkull ble gjennomført for 10 studentgrupper. Prosjektet er en kvalitativ kasusstudie og analyse er gjort etter inspirasjon av Giorgi‘s empiriske fenomenologi. Diskusjonen tar utgangspunkt i Vygotsky‘s sosiokulturelle syn på læring og Dewey‘s prinsipp om at all læring er basert på erfaring. Funnene er presentert i følgende deler: Første del omhandler videodokumentasjon og refleksjon. De to neste delene viser funn i forhold til mesterlæring og situert læring på vei mot forståelse av hva sykepleie er. Deretter er teknisk utfordringer belyst, og til slutt en drøfting av forhold ved oppøving av praktiske sykepleieferdigheter. Konklusjonen her er at video egner seg til å dokumentere sykepleiehandlinger. Dette har størst verdi for læring og refleksjon, i mindre grad som eksamensform.

    Fundamental knowledge of microscopic anatomy and pathology has always been an essential part in medical education. The traditional didactic concept comprises theoretical and practical lessons using a light microscope and glass slides. High-speed Internet connections and technical improvement in whole-slide digital microscopy (commonly termed "virtual microscopy") provide a new and attractive approach for both teachers and students. High picture quality and unlimited temporal and spatial availability of histology samples from different fields are key advantages of web-based digital microscopy. In this report we discuss the technical requirements, system efficiency, optical resolution and didactic concept. Furthermore, we present a review of the experience gained in the course of one year based on an analysis of student acceptance. Three groups with a total of 192 students between the 3rd and 5th year of medical studies attending the practical courses of general and advanced histopathology had access to both glass-mounted and digitalized slides. Prior to exams, students were asked to answer an anonymous questionnaire. The results of the study reflect the high acceptance and intensive use of the web-based digital histology by students, thus encouraging the development of further Web-based learning strategies for the teaching of histology and pathology. 2010 Elsevier GmbH.

    Topics discussed in this volume include shock wave structure, propagation, and interaction; shocks in condensed matter, dusty gases, and multiphase media; chemical processes and related combustion and detonation phenomena; shock wave reflection, diffraction, and focusing; computational fluid dynamic code development and shock wave application; blast and detonation waves; advanced shock tube technology and measuring technique; and shock wave applications. Papers are presented on dust explosions, the dynamics of shock waves in certain dense gases, studies of condensation kinetics behind incident shock waves, the autoignition mechanism of n-butane behind a reflected shock wave, and a numerical simulation of the focusing process of reflected shock waves. Attention is also given to the equilibrium shock tube flow of real gases, blast waves generated by planar detonations, modern diagnostic methods for high-speed flows, and interaction between induced waves and electric discharge in a very high repetition rate excimer laser.

    In no more than five months` construction time two roofs of Magdeburg University were fitted with a solar water heating plant for the cantine building and neighbouring students` homes. The plant is to deliver 300,000 kWh of energy per year thus saving 37,000 m{sup 3} of natural gas and 70 t of CO{sup 2} in this time. The plant was sponsored under the ``Solarthermie 2000 Project`` and planned by Dr. Valentin Planning Engineers in Berlin. The total cost of the plant, which is currently undergoing trial runs, is expected to amount to 690,000 marks, this implying heating costs of approx 23 pfennigs per kWh. (orig.)

    2012-06-01

    Dat supervisie essentieel is binnen het beroep van sociaal werk, daar zijn sociaal werkers het al langer over eens. Supervisie krijgt binnen de opleiding sociaal werk dan ook een belangrijke plaats. In supervisie leren studenten (eerste werkervaringen te analyseren, eigen indrukken en gevoelens te onderzoeken en hun visie op het werkveld te verruimen en dit onder begeleiding van een supervisor. Studenten leren tevens de reeds verworven theorie om te zetten in de praktijk. Voor het merendeel van de studenten is dit geen eenvoudige klus. Zij hebben dan vele morele en ethische vragen over hun handelen. Aangezien de waarden en normen binnen het sociaal werkveld niet statisch en eenduidig zijn, is het soms ook erg verwarrend wat nu juist “juist” handelen is. Binnen een supervisiegroep kunnen hier bij de verschillende studenten en supervisor meerdere meningen over bestaan. Daarom wordt de methodiek “Ethische cirkels in sociaal werk” toegelicht in dit artikel. Deze methode kan een houvast bieden voor studenten en supervisor om aan de slag te gaan met ethische vragen.

    Full Text Available Artikkelen presenterer en undersøkelse av muntlige eksamener i lærerutdanning, og den besvarer spørsmålet om interaksjon som kommer av at eksaminator henviser til og følger opp en students utsagn underveis i eksaminasjonen, bidrar til å fremme argumentasjon i studentens eksamensbesvarelse. Styringsdokumenter for lærerutdanning har fremstilt argumentasjonsevne som en del av kompetansen lærerstudenter skal tilegne seg, og faglitteratur har fremstilt muntlig eksamen som en vurderingsform med særlig stort rom for argumentasjon. Forskningsgrunnlag for slik fremstilling av muntlig eksamen har blitt etterlyst. Tidligere har intervjuundersøkelser av studenters og eksaminatorers erfaringer med muntlig eksamen blitt brukt til å vurdere hva som fremmer argumentasjon. Undersøkelsen som ligger til grunn for denne artikkelen, har i stedet brukt lydopptak av muntlige eksamener for å kunne avdekke faktiske forekomster av argumentasjon og sammenhenger det skjer i, og lagt det til grunn for vurdering av hva som fremmer argumentasjon. Resultatet av undersøkelsen er at argumentasjon forekommer langt oftere enn ellers i studentenes besvarelser i sammenhenger hvor eksaminator henviser til og følger opp noe av det studentene sier, og det tolkes som indikasjon på at interaksjon som kommer av slik opptreden hos eksaminator, bidrar til å fremme argumentasjon i studentenes eksamensbesvarelser.

    Full Text Available Das intelligente Tutorensystem LARGO für die Rechtswissenschaften soll Jurastudenten helfen, Argumentationsstrategien zu lernen. Im verwendeten Ansatz werden Gerichtsprotokolle als Lernmaterialien verwendet: Studenten annotieren diese und erstellen graphische Repräsentationen des Argumentationsverlaufs. Das System kann dabei zur Reflexion über die von Anwälten vorgebrachten Argumente anregen und Lernende auf mögliche Schwächen in ihrer Analyse des Disputs hinweisen. Zur Erkennung von Schwächen verwendet das System Graphgrammatiken und kollaborative Filtermechanismen. Dieser Artikel stellt dar, wie in LARGO auf Basis der Bestimmung eines „Benutzungskontextes“ die Rückmeldungen im System benutzungsadaptiv gestaltet werden. Weiterhin diskutieren wir auf Basis der Ergebnisse einer kontrollierten Studie mit dem System, welche mit Jurastudierenden an der University of Pittsburgh stattfand, in wie weit der automatisch bestimmte Benutzungskontext zur Vorhersage von Lernerfolgen bei Studenten verwendbar ist.

    Full Text Available Das Phänomen Liebe nicht - wie im Alltagsgebrauch - als substantielle Entität, sondern als kommunikativ erzeugte Lebenswirklichkeit zu begteifen, ist Ziel der Untersuchung gewesen. Zu diesem Zweck wurde eine vergleichende Fallstudie zum Liebeskonzept brasilianischer und deutscher Studenten durchgeführt. Theoretische Grundlage der Untersuchung bildete ein im weitesten Sinne konstruktivistisches Verständnis von Kommunikation als wirklichkeitserzeugendem Verhaltensbereich. In einer theoretischen Einführung wurde der Wirklichkeitsbereich Liebe unter Einbeziehung des jeweiligen historisch-kulturellen Hintergrundes fokussiert. Die methodische Vorgehensweise bei der Durchführung der Studie war schließlich überwiegend qualitativ angelegt, um das für den Einzelnen tatsächlich relevante Begriffsinventar ermitteln zu können. In der Auswertung sind dann die Unterschiede im Hinblick auf die Internalisierung eines Liebesideals, die Strukturen der Beziehungswirklichkeit, ihre sprachliche Handhabung, die Verhaltenskoordination, die Funktion von Beziehungen sowie die Folgen für die Kommunikationspraxis herausgestellt worden. Es zeigte sich, dass Liebesbeziehungen unter deutschen Studenten stark vom romantischen Liebesideal geprägt sind, unter brasilianischen Studenten dagegen am ehesten dem passionierten Liebesiedel entsprechen.

    The paper deals with the indication of computerized tomography on patients with a hypernephroma. The experience gained with patients of the Radiological Division of the Medical Faculty of the University of Aachen were compared to results obtained by other authors. As for the diagnosis, a definite assessment of the results of literature was possible only partly as the patients in Aachen were usually nephrectomised. Computerized tomography is able to improve the planning of the radiation. Searching for metastases, there were some advantages, but also disadvantages compared to the conventional radiological methods. In course control and posttreatment, computerized tomography offers completely new possibilities. (orig./MG) [de

    response rate is comparably high, non-response by part of the students may alter the estimated figures. The study only includes students from one German medical school. Longitudinal data are absent. A longitudinal study has been initiated.Conclusions: There is a high rate of resignation and burnout behavioral patterns among medical students, while healthy patterns decrease the further the students progress in their professional training. There are significant gender differences in the psychosocial patterns.Students express a high need for preventive techniques and interventions. Thus prevention of psychosocial morbidity and motivational interventions are important issues in the training of future physicians. Such interventions should become a mandatory part of the medical curriculum and should take gender aspects into consideration.[german] Hintergrund: Epidemiologische Daten zur Gesundheit von Ärzten und Medizinstudenten zeigen im Vergleich zur Allgemeinbevölkerung eine erhöhte psychische Morbidität.

  15. Rudolf Hermann, wind tunnels and aerodynamics

    Lundquist, Charles A.; Coleman, Anne M.

    2008-04-01

    Rudolf Hermann was born on December 15, 1904 in Leipzig, Germany. He studied at the University of Leipzig and at the Aachen Institute of Technology. His involvement with wind tunnels began in 1934 when Professor Carl Wieselsberger engaged him to work at Aachen on the development of a supersonic wind tunnel. On January 6, 1936, Dr. Wernher von Braun visited Dr. Hermann to arrange for use of the Aachen supersonic wind tunnel for Army problems. On April 1, 1937, Dr. Hermann became Director of the Supersonic Wind Tunnel at the Army installation at Peenemunde. Results from the Aachen and Peenemunde wind tunnels were crucial in achieving aerodynamic stability for the A-4 rocket, later designated as the V-2. Plans to build a Mach 10 'hypersonic' wind tunnel facility at Kochel were accelerated after the Allied air raid on Peenemunde on August 17, 1943. Dr. Hermann was director of the new facility. Ignoring destruction orders from Hitler as WWII approached an end in Europe, Dr. Hermann and his associates hid documents and preserved wind tunnel components that were acquired by the advancing American forces. Dr. Hermann became a consultant to the Air Force at its Wright Field in November 1945. In 1951, he was named professor of Aeronautical Engineering at the University of Minnesota. In 1962, Dr. Hermann became the first Director of the Research Institute at the University of Alabama in Huntsville (UAH), a position he held until he retired in 1970.

  16. Situasjonsbestemt ledelse av studentgrupper i friluftsliv

    Directory of Open Access Journals (Sweden)

    Odd Lennart Vikene

    2014-05-01

    Full Text Available Artikkelen gir et praktisk eksempel på hvordan ulike studentgrupper i forbindelse med bygging av nødbivuakk i vinterfjellet opplevde min situasjonsbestemte ledelse som veileder. Teorigrunnlaget viser til situasjonsbestemte ledelsesmodeller og hva som kjennetegner god veiledning i friluftsliv. Datainnsamlingen bygger på kvantitative data fra et spørreskjema og benyttes til å analysere studentenes opplevelse av veileders ledelse ut i fra rangeringsmetoden Visuell Analog Skala (VAS. Fra samme spørreskjema var det også et åpent spørsmål som benyttes til refleksjon over studentenes opplevelse av sikkerhet i undervisningssituasjonen. Resultatene viser at studentgruppene opplevde klare ledelsesforskjeller gjennom de ulike fasene som ledelsen ble delt opp i, men at ledelsesatferden varierte lite i forhold til gruppenes erfaringsgrunnlag. Resultatene tyder på at jeg som veileder i stor grad har blitt påvirket av mine tidligere erfaringer og den potensielle risikoen som ligger ved aktiviteten. Selv om den situasjonsbestemte ledelsen varierte lite mellom de tre gruppene, viser resultatenes store standardavvik at de ulike smågruppene opplevde at ledelsen varierte. Dette tyder på at jeg som veileder til en viss grad har evnet å benytte situasjonsbestemt ledelse i praksis. På grunn av studentgruppenes relativt like oppfatning av ledelsen i de ulike fasene, viser resultatene også noe av vanskelighetene veileder har i forhold til å gjøre en korrekt vurdering av gruppens evner og erfaring i relasjon til læringssituasjonene som oppstår. Sentralt for ledelsen er likevel at studentgruppene opplevde ledelsen som betryggende, noe som gir studentene et godt grunnlag for senere opplevelser i tilknytning til vinterfriluftsliv og bygging av nødbivuakk.

Thereafter, an alternating magnetic field generates heat which may be used to release the thermosensitively bound drug and for hyperthermia. Until today, only superficial tumors can be treated with this method. Our aim was to transfer this method into an endoscopic setting to also reach the majority of tumors located inside the body. To find the ideal endoscopic magnetic field trap, which accumulates the most SPION, we first developed a biophysical model considering anatomical as well as physical conditions. Entities of choice were esophageal and prostate cancer. The magnetic susceptibilities of different porcine and rat tissues were measured with a superconducting quantum interference device. All tissues showed diamagnetic behavior. The evaluation of clinical data (computed tomography scan, endosonography, surgical reports, pathological evaluation of patients gave insight into the topographical relationship between the tumor and its surroundings. Both were used to establish the biophysical model of the tumors and their surroundings, closely mirroring the clinical situation, in which we could virtually design, place and evaluate different electromagnetic coil configurations to find optimized magnetic field traps for each tumor entity. By simulation, we could show that the

    Full Text Available Artikkelen diskuterer hvordan wiki kan brukes i engelskundervisning for å la nye og tradisjonelle tekster møtes i digital dialogisk interaksjon. Med utgangpunkt i begrepene multimodalitet, hypertekstualitet og prosessualitet, tre egenskaper som i følge Ture Schwebs (2006 skiller digitale tekster fra analoge, diskuterer artikkelen et eksempel fra et undervisningopplegg for lærerstudenter. Basert på et bilde skapte studentene et felles nettsted og en kollektiv, fiktiv, men realistisk historie. Historien dannet så i neste omgang en ramme for produksjon av tekster i ulike modaliteter og sjangre. Bildet etablerte en bestemt historisk og kulturell kontekst som studentene aktivt måtte utforske for å skape sine tekster. Wikiens funksjonaliteter åpnet opp for samskriving, utvikling av ferdigheter for å tolke og skape tekster med sammensatte modaliteter, utnyttelse av hypertekstens struktur og samarbeid om tekstskaping som prosess på tvers av tid og rom. Dette er kunnskaper og ferdigheter framtidige lærere vil trenge.

    Full Text Available Wissenschaftler aus den Bereichen Erziehungswissenschaft, Angewandte Linguistik und Fremdsprachenlehrerausbildung beschäftigen sich immer häufiger mit Fragen der Einbeziehung von Informations- und Kommunikationstechnologien in die Lehramtsausbildung und der Notwendigkeit, die Entwicklung kritisch reflektierender Lehrer während der Ausbildung zu fördern. Theoretische Studien über Merkmale der Informationsgesellschaft, über virtuelle Lernumgebungen und über die Lehrerausbildung dienen als Basis für den vorliegenden Artikel, dessen Ziel es ist, die Möglichkeiten der Anwendung der Lernplattform Moodle in der Deutschlehrerausbildung zu diskutieren. Zu diesem Zweck stellen wir verschiedene Möglichkeiten vor, einige virtuelle Umgebungen und die von ihnen angebotenen Werkzeuge zu nutzen, die nachweislich großen Einfluss sowohl im Verlauf der Ausbildung selbst, als auch bei der Unterstützung der Studenten während ihrer Praktika haben. Empirisch zeigt sich, dass die virtuellen Lernumgebungen unschätzbare Vorteile als Hilfsmittel für die Begleitung der Studenten beim Sprachlernprozess und bei den ersten Lehrerfahrungen mit sich bringen.

    Full Text Available Using dictator games in experimental analysis, this lesson report demonstrates the process and results of a postgraduate class project in which university students were instructed to scientifically investigate and explore one of German society’s most hotly-contested issues: the level of discriminatory tendencies of non-Muslims towards Muslims. The results of this class project show little or no discriminatory tendencies toward Muslims. Instead, the university students under our investigation tended to act favorably, or at the very least, fairly toward Muslims. We expect that this lesson report can demonstrate how a postgraduate course can be conducted in an innovative way, empowering students to collect primary data and finishing a small scientific project during the span of a semester. Dieser Bericht stellt die Prozesse und Ergebnisse einer experimentellen Studie eines Postgraduierten-Kurses der Universität Greifswald dar. Wir zeigen, wie Studierende das Thema Migration innovativ untersuchen können, indem sie neben theoretischen Lerninhalten an experimentelle Methoden sowie die Primärforschung herangeführt werden. Anhand eines Diktatorspiels wurden die teilnehmenden Studenten angeleitet, ein in der Öffentlichkeit kontrovers debattiertes Thema wissenschaftlich zu untersuchen: Diskriminierende Tendenzen von Nicht-Muslimen gegenüber Muslimen. Die Ergebnisse dieser Studie lassen jedoch nicht auf diskriminierende Tendenzen der Studenten schließen. Stattdessen deuten sie darauf hin, dass sich die Studierenden zumindest fair gegenüber Muslimen verhalten.

    Full Text Available Ziel dieses Beitrags ist es, einen Bereich zu analysieren, der im europäischen Referenzrahmen nicht ausreichend definiert, jedoch von zentraler Bedeutung für das berufliche Lernen unserer Studenten ist: der des wissenschaftlichen Schreibens. Die Professoren und Dozenten unserer Forschungsgrup­pe, die auf diesem Gebiet vor allem in der englischen Fremdsprache tätig ist, halten es für notwen­dig, den Lernenden klare Anweisungen zu strukturellen und rhetorischen Elementen vorzugeben. Innerhalb der 24 Wochen, die unser Kurs zum wissenschaftlichen Lesen und Schreiben dauert, ist es schwierig, die Kompetenz der Studenten in der englischen Sprache an sich wesentlich zu ver­bessern, aber, und das zeigen unsere Ergebnisse, können auch Studierende auf der B1.1-Stufe des Oxford Placement Tests (Ergebnis 32/100 von den klaren Anweisungen zum Schreiben profitieren. Das Ergebnis ihrer Leistungen insgesamt verbessert sich bis zum Ende des Kurses erheblich und scheint sich dem B2.1-Niveau anzunähern.

    2012-10-01

    In 1912 Professor Hans Reissner of the Technical University Aachen built a canard-type aeroplane, the world-wide first completely out of metal: although the Reissner Canard initiated a new technology with the Junkers J1 the first to follow in 1915 and 1000 more until now, little is known about the very first steps way back in Aachen. This paper tries to recapture some details of the developments 100 years ago with the aid of early publications and photographs and shed some light on the first wing fabricated out of a corrugated aluminum sheet mounted at the tail of the braced-steel-pipe fuselage to earn its airworthiness in Berlin Johannisthal in 1912.

    Spontaneous language of 18 patients suffering from Huntington's disease and 15 dysarthric controls suffering from Friedreich's ataxia were investigated. In addition, language functions in various modalities were assessed with the Aachen Aphasia Test (AAT). The Huntington patients exhibited deficits in the syntactical complexity of spontaneous speech and in the Token Test, confrontation naming, and language comprehension subtests of the AAT, which are interpreted as resulting from their dementia. Errors affecting word access mechanisms and production of syntactical structures as such were not encountered.

Bosutinib effectively inhibits wild-type BCR-ABL and most imatinib-resistant BCR-ABL mutations except for V299L and T315I. Low hematologic toxicity is a remarkable characteristic of this novel second-generation tyrosine kinase inhibitor, and this has been ascribed to its minimal activity against the platelet-derived growth factor receptor and KIT. Low-grade, typically self-limiting diarrhea, which usually appears within the first few weeks after treatment initiation, represents the predominant toxicity of bosutinib. Other treatment-associated adverse events are mostly mild to moderate. Bosutinib has been approved by the US Food and Drug Administration for the treatment of chronic, accelerated, or blast phase Philadelphia chromosome-positive CML in adult patients with resistance or intolerance to prior therapy. This review summarizes the main properties of bosutinib and the currently available data on its clinical potential in the treatment of CML.Keywords: bosutinib, chronic myeloid leukemia, BCR-ABL, Src/Abl kinase inhibitor, point mutation, imatinib resistance

    Full Text Available Digitale ferdigheter i skole og høyere utdanning tolkes ofte som evnen til å utnytte digitale verktøy i læringsarbeid. Artikkelen argumenterer for at lærerutdanningen også bør fokusere på digital teknologi som tema i tillegg til å betrakte teknologi som hjelpemiddel for å oppnå læring i de ulike fagene. I det følgende beskrives et undervisningsopplegg i samfunnsfag hvor første års lærerstudenter settes til å skrive en fagrelatert artikkel på Wikipedia. Gjennom ulike typer data analyseres hvilke innsikter som åpner seg for studentene når de selv skaper innhold de hittil bare har forholdt seg til som konsumenter. Artikkelen peker på at studentene gjør en rekke vesentlige oppdagelser underveis, men at det fortsatt er sider ved denne type kunnskapsproduksjon de ikke helt forstår. Artikkelen argumenterer for at opplegget likevel har sin berettigelse fordi det gir studentene en sjelden anledning til å tematisere viktige sider av digital teknologi på en måte som er både relevant og gjennomførbar innenfor de faglige rammene i lærerutdanningen.Nøkkelord: digital kompetanse, lærerutdanning, lærerstudenter, Wikipedia, wiki, digitale verktøy, digitale ferdigheterAbstractIn schools and in higher education, we often understand digital skills as the ability to use various digital tools for learning.

A range of data are used to analyze some of the self-reported insights that open up to the students when they themselves become contributors of content they normally deal with exclusively as consumers. The study shows that although the students make a series of discoveries after becoming editors, they do not fully comprehend

  11. Quantenmechanik verstehen eine Einführung in den Welle-Teilchen-Dualismus für Lehrer und Studierende

    2003-01-01

    Der bekannte Autor H. Pietschmann wendet sich mit diesem Buch an Physiklehrer an höheren Schulen und an Physikstudenten im Anschluß an deren Grundausbildung. Quantenmechanik entzieht sich der Anschaulichkeit, wie wir sie von der klassischen Physik her kennen, aber - und das ist das Kernthema des Buchs - man kann sie sehr wohl verstehen. H. Pietschmann gelingt es, dies mit einfachen Mitteln zu erreichen, und damit gibt er Lehrerinnen und Lehrern eine Unterrichtshilfe und Studenten eine Einführung in die anspruchsvollen Hochschultexte an die Hand. Die mathematische Behandlung spielt keine zentrale Rolle, vielmehr wird versucht, der Interpretation und dem Denken in quantenmechanischen Kategorien breiten Raum zu geben. Behandelt werden z.B. die Quantenhypothese unter Einbeziehung der Geschichte dieses Konzepts, die Schrödingertheorie, die Interpretation der Wellenfunktion und der Messprozess, die Ein- und Mehrelektronenatome sowie Fragen der Zeitabhängigkeit.

    Full Text Available Dieser Beitrag beschäftigt sich kontrastiv mit dem Gebrauch von Verzögerungssignalen in deutschen und finnischen Seminardiskussionen. Die voranalytische  Durchsicht der Videomitschnitte zeigte, dass die deutschen Studenten unvergleichlich  häufiger die Verzögerungspartikeln äh und ähm  einsetzten als ihre finnischen Kommilitonen, die in ähnlicher Funktion v.a. die Partikel niinku ('sozusagen' benutzten. Diese  Beobachtung ist insofern von Bedeutung, als es meist die finnischen Gesprächsteilnehmer sind, die in deutsch-finnischen Kontaktsituationen auf eine Fremdsprache (Deutsch  zurückgreifen müssen: Möglicherweise steht finnischen Gesprächspartnern in der Interaktion mit deutschen Muttersprachlern keine deutsche Entsprechung für niinku zur Ver- fügung. Gegebenenfalls resultierende Kommunikationsprobleme sollten dementsprechend nicht vornehmlich interkulturell, sondern interlingual bewertet werden.

    Full Text Available Søkelyset settes her på norsk lærerutdanning og på grunnskolelærerstudenters veiledningssamtaler i praksisopplæring hvor Lesson Study ble innført som arbeidsmetode. Analysen fra studentenes veiledningssamtaler forsøker å identifisere muligheter og begrensninger ved innføring av Lesson Study der samtalefokus er elevers læring knyttet til et bestemt tema i en forskningstime. Et teoretisk og analytisk rammeverk benyttes (Bransford, Brown, & Cocking, 2000 for å identifisere elevsentrerte, kunnskapssentrerte, vurderingssentrerte og felleskapssentrerte ytringer i veiledningssamtalene. Slike ytringer blir knyttet til tre sentrale aspekter ved planlegging og gjennomføring av en forskningstime i en Lesson Study syklus: Elevobservasjon, prediksjon og forskningsspørsmål. Resultater fra analysene av veiledningssamtaler fra to studentgrupper tilknyttet naturfag og matematikk viste store forskjeller med tanke på gruppenes planlegging av en Lesson Study syklus. Studentene i matematikk valgte å legge opp undervisningen ut ifra lærebokens nivåinndeling av lærestoffet, noe som ser ut til å virke hemmende med tanke på elevobservasjon og prediksjon knyttet til det faglige emnet. Studentene i naturfag var mye mer opptatt av å formulere gode læringsmål og forskningsspørsmål. I denne veiledningssamtalen var det også et tydelig fokus på prediksjon samt aktiv elevobservasjon under gjennomføringen av undervisningsøkten. Resultater fra denne studien påpeker behov for et grundig forarbeid på campus av faglærere ved utdanningsinstitusjonen slik at studentene får muligheten til å forberede en Lesson Study syklus der forskningsspørsmål, elevobservasjon og prediksjon er sentrale hovedmomenter som løftes fram. Videre er det behov for et godt samarbeid mellom faglærere og praksislærere ved skolene for at implementering av Lesson Study skal være vellykket.Abstract In this article, we present a study of field practice during Initial

    . Seit 20 Jahren werden somit stetig neue virtuelle Lernprogramme auch für die Histologie entwickelt. Entsprechende Entwicklungen haben dadurch die Lernmethoden der Studenten zum Wissenserwerb und zur Prüfungsvorbereitung beeinflusst. Die Lehre sollte Seminare, Vorlesungen und Laborarbeiten dementsprechend anpassen. Als einen ersten Schritt wurde eine Sammlung digitaler mikroskopisch-histologischer Bilder für die Studenten an der FSU Jena zur Verfügung gestellt. Das Ziel dieser Studie ist es den Stellenwert des konventionellen Lichtmikroskops im derzeitigen Selbststudium der Studenten der Human- und Zahnmedizin im Vergleich zu digitalen Medien herauszufinden. Dazu wurde eine Umfrage unter 172 Human- und Zahnmedizinstudenten an der Friedrich-Schiller-Universität Jena durchgeführt. Die Ergebnisse lassen einen deutlichen Unterschied mit 51% Nutzung neuer Medien gegenüber früheren ähnlichen Studien mit 5% Nutzung erkennen. Es zeigt, dass digitale Medien wie Internet und CD- oder computergestützte Lernprogramme sich beim Selbststudium der Studenten der Human- und Zahnmedizin als ein Konkurrenzsystem zum klassischen Lichtmikroskop entwickelten.

    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. Es erfordert aber mitunter grossen baulichen Aufwand, diese Forderungen zu

The field of DS’ research focus on the use of personal narratives in the learning process, multimedia, and the creative process in developing identity and voice in a social context: the Story Circle. The frame is Workplace-based Kindergarten Teacher Education. The article is based on a case: student Yvonne’s work with DS in her kindergarten. Data is collected through observation and analyzed in light of theories on learning in practice, concretized to Kolb's experiential learning cycle. Results indicate that DS is a beneficial approach for facilitating both individual and collective reflection. A significant condition is that kindergarten staff participates in students' learning processes. Sammendrag: Artikkelen tar for seg barnehagelærerstudenters og barnehageansattes bruk av digital historiefortelling (DH, som er en arbeidsmåte for refleksjon og læring i høyere utdanning. DH kjennetegnes ved: fortellingens betydningen for læring i forhold til tradisjonell sakprosa, den multimodale dimensjonen og den kreative prosessen hvor fortellingen blir til i en sosial kontekst: fortellersirkelen. Rammen er Arbeidsplassbasert barnehagelærerutdanning. Artikkelen baseres på et case: studenten Yvonnes arbeid med DH i egen barnehage. Data er innhentet gjennom observasjon og fortolkes i lys av teorier om læring i praksis, konkretisert til Kolbs erfaringslæringsmodell. Jeg viser at DH tilrettelegger for individuell og kollektiv refleksjon for både studenter og barnehageansatte. Forutsetningen er at ansatte gis muligheter til å delta i studentenes læringsprosesser.

    Full Text Available Danningsprosesser i barnehagelærerutdanningen skjer i skjæringspunktet mellom teori og praksis og er særlig knyttet til profesjonsdannelse. Som pedagogikklærere i utdanningen er vi opptatt av å legge til rette for undervisningssituasjoner som gir mening for studentene. Vår praksis er fundert i ulike perspektiver på danning, og skjer innenfor noen didaktiske rammer som gir føringer for undervisningen. For å bli mer bevisste på de pedagogiske danningsperspektivene vi er en del av, har vi sett på hvordan analyse av praksisfortellinger kan åpne opp for og invitere studentene inn i danningsprosesser. Vi diskuterer våre inntrykk og erfaringer med denne læringsstrategien ut fra to teoretiske hovedperspektiver på danning og i forhold til de overordnede samfunnsmessige rammene undervisninger opererer innenfor. Den etiske dimensjon er også sentral i artikkelen. Summary Preschool teacher educationPreschool teacher education takes place in the meeting place between theory and practice and is in particular related to professional training. As instructors in pedagogy within education, we are committed to facilitating teaching situations that are meaningful to students. Our practice is grounded in different perspectives on education and occurs within a didactic framework that provides guidelines for teaching. To increase knowledge about the pedagogical perspectives we use, we have looked at how shared reflection on practical situations can open up and invite students into the bildung process. We discuss our impressions and experiences with this learning strategy based on two main theoretical perspectives on bildung and in relation to the overall societal framework in which teachings operates. The ethical dimension is also central to the article.

    Full Text Available UiT Norges arktiske universitet har gjennomført en nasjonal pilot i grunnskolelærerutdanning på masternivå, hvor de første studentene fullførte utdanningen og leverte masteroppgave våren 2015. Denne artikkelen fokuserer på hvilken relevans studentene opplever at masteroppgaven har for den fremtidige profesjonsutøvelsen deres. Å undersøke studentenes oppfatning av masterarbeidet er av betydning, ikke bare fordi masterutdanning blir en nasjonal ordning fra 2017, men også for å utvikle kunnskap om betydningen av forsknings- og utviklingskompetanse for grunnskolelærere. Studiens empiriske materiale er en intervjuundersøkelse med 22 av de 61 første masterstudentene. Undersøkelsen inngår i en longitudinell studie som vil belyse nyutdannedes profesjonslæring i starten av karrieren, og konkret hvordan lærere integrerer kunnskapen fra utdanningen med kunnskap og erfaringer de utvikler som ferske lærere. Resultatene fra denne delstudien viser at masterarbeidet har gitt studentene dybdekunnskap og FoU-kompetanse som er av betydning for den videre profesjonsutøvelsen. Studien viser også at det er betydningsfullt at masteroppgaven har forankring i skolens praksis og bidrar til utviklingen som lærer. Av materialet fremgår det også at studentene fremhever selvstendighet og evne til samarbeid, og de er stolte av masterarbeidet sitt. Resultatene er drøftet opp mot begrepene konseptuell og kontekstuell kunnskap (Afdal & Nerland, 2012; Muller, 2009 og i lys av profesjonsteori. Masterarbeidet synes avgjørende for profesjonsidentiteten, men det vil kreves et systematisk utviklingsarbeid for å kunne gi masterarbeidet kvaliteter som kan støtte opp om studentenes utvikling som profesjonelle lærere. For lærerutdanningene tilsier dette at FoU-kompetanse må gis oppmerksomhet fra første dag i utdanningen.Nøkkelord: grunnskolelærerutdanning, masteroppgave, nyutdannet lærer, FoU-kunnskap, profesjonell identitet, profesjonsidentitet

    The drift velocity is a key parameter of drift chambers. Its value depends on several parameters: electric field, pressure, temperature, gas mixture, and contamination, for example, by ambient air. A dedicated Velocity Drift Chamber (VDC) with 1-L volume has been built at the III. Phys. Institute A, RWTH Aachen, in order to monitor the drift velocity of all CMS barrel muon Drift Tube chambers. A system of six VDCs was installed at CMS and has been running since January 2011. We present the VDC monitoring system, its principle of operation, and measurements performed.

    The drift velocity is a key parameter of drift chambers. Its value depends on several parameters: electric field, pressure, temperature, gas mixture, and contamination, for example, by ambient air. A dedicated Velocity Drift Chamber (VDC) with 1-L volume has been built at the III. Phys. Institute A, RWTH Aachen, in order to monitor the drift velocity of all CMS barrel muon Drift Tube chambers. A system of six VDCs was installed at CMS and has been running since January 2011. We present the VDC monitoring system, its principle of operation, and measurements performed.

  19. Basic concepts of automation and mechatronics with LEGO mindstorms NXT

    2014-01-01

    Full Text Available Mindstorsms LEGO NXT is using in engineering education at well recognized engineering schools like RWTH Aachen University where is created the RWTH - Mindstorms NXT Toolbox for Matlab. MATLAB / Simulink is widely available and popular for students around the world, but software toolboxes which are required for work with the real time systems are too expensive for the universities, especially those in developing countries. This paper describes an approach that is currently used in introductory subjects in the field of automation and mechatronics at the University of Kragujevac, and that does not require expensive software support.

    CERN. Geneva; Thiele, Robert

    2017-01-01

    An important base of the common JOIN2 repository infrastructure of DESY, DKFZ, FZJ, GSI, MLZ and RWTH Aachen are about 134 000 authority records for grants, projects, large-scale infrastructures, cooperations, journals, and different kinds of keys. All instances are using the authorities together. We will present how these authority data are used for different purposes e.g. the recent and upcoming obligations to report to regard to our funding and the data export to openAire. Furthermore, we discuss this in dependence to the German “Kerndatensatz Forschung”, which will be the new standard for future.

    Based on a new dataset of Prussian joint stock companies founded before 1870 this article indicates that early German joint stock companies were concentrated in a few highly developed regions. After the region became Prussian in 1815 the Rhine Province with its favourable institutional environment...... due to the persistence of French law (Code de Commerce) hosted a very large part of the Prussian industrial joint stock companies. Qualitative analysis of early joint stock companies in the industrial district of Aachen shows that the new institution allowed for related diversification of industrial...

  4. Assembly of Drift Tubes (DT) Chambers at CIEMAT (Madrid)

    The construction of muon drift tube chambers (DT) has been carried out in four different european institutes: Aachen (Germany), CIEMAT-Madrid (Spain), Legnaro and Turin (Italy), all of them following similar procedures and quality tests. Each chamber is composed by three or two independent units called superlayers, with four layers of staggered drift cells each. The assembly of a superlayer is a succesive glueing of aluminium plates and I-beams with electrodes previously attached, forming a rectangular and gas-tight volume. These pictures illustrate the various processes of material preparation, construction, equipment and assembly of full chambers at CIEMAT (Madrid).

  5. An environmentally friendly technology for the carbonisation of low ranked coal and biomass

    Between 1997 and 2001 the Federal Institute for Geosciences and Natural Resources in connection with the Coking Group of the Aachen University of Technology developed a environmentally friendly process for the carbonisation of low ranked coals and biomass. The main tasks of finished investigations have been, to produce an economically competitive carbonisate to substitute wood and charcoal on local markets and to protect local forests. So far the project covered examinations on the behaviour of the pyrolysis of brown coals and biomass in a shaft reactor at Kuching, Malaysia, and a pilot rotary kiln reactor at Aachen. During test runs burning and briquetting tests were carried out with selected coals and biomass from Brazil, Thailand, Malaysia, Indonesia and the Phillipines. Also some coals from near east countries have been tested. To ensure thermally autarkic operation, the appropriate moisture and ash contents of the feed material were determined and a temperature based controlling system has been developed. Finally all tested materials allowed the production of a smokeless carbonisate under thermically autarkic operation. After finishing the test with a shaft reactor (feed up to 100 kg/h) the building of a rotary kiln pilot plant (feed 300 kg/h) as preproduction phase for commercial use (feed 3 - 5 t/h) is scheduled in 2002. First economic calculations on a rotary kiln operation demonstrated, that the carbonisate is competitive with local fuels such as kerosene, petroleum and gas. Additionally some carbonisates fit the quality standards for direct activation. 3 refs., 11 figs., 2 tabs.

    On March 14, 2006, first cosmic muon tracks have been measured in the Tracker EndCap TEC+ of the CMS silicon strip tracker. The end caps have silicon strip modules mounted onto wedge-shaped carbon fiber support plates called petals. Up to 28 modules are arranged in radial rings on both sides of these plates. One eighth of an end cap (called sector) is populated with 18 petals. The TEC+ endcap is currently being integrated at RWTH Aachen. 400 silicon modules with a total of 241664 channels, corresponding to one eighth of the endcap, are read-out simultaneously by final power supply and DAQ components. On the left is the TEC+ in Aachen, whilst on the right is a computer image of a cosmic ray traversing the many layers of silicon sensors. To understand the response to real particles, basic functionality testing was followed by a cosmic muon run. A total of 400 silicon strip modules are read out with a channel inefficiency of below 1% and a common mode noise of only 25% of the intrinsic noise.

    Early detection of respiratory overload is crucial to mechanically ventilated patients, especially during phases of spontaneous breathing. Although a diversity of methods and indices has been established, there is no highly specific approach to predict respiratory failure. This study aimed to evaluate acceleration sensors in abdominal and thoracic wall positions to detect alterations in breathing excursions in a setting of gradual increasing airway resistance. Twenty-nine healthy volunteers were committed to a standardized protocol of a two-minutes step-down spontaneous breathing on a 5 mm, 4 mm and then 3 mm orally placed endotracheal tube. Accelerator sensors in thoracic and abdominal wall position monitored breathing excursions. 15 participants passed the breathing protocol ("completed" group), 14 individuals cancelled the protocol due to subjective intolerance to the increasing airway resistance ("abandoned" group). Gradual increased respiratory workload led to a significant decrease of acceleration in abdominal wall position in the "abandoned" group compared to the "completed" group (p breathing alterations prior to respiratory failure.

    Especially for investigator-initiated research at universities and academic institutions, Internet-based rare disease registries (RDR) are required that integrate electronic data capture (EDC) with automatic image analysis or manual image annotation. We propose a modular framework merging alpha-numerical and binary data capture. In concordance with the Office of Rare Diseases Research recommendations, a requirement analysis was performed based on several RDR databases currently hosted at Uniklinik RWTH Aachen, Germany. With respect to the study management tool that is already successfully operating at the Clinical Trial Center Aachen, the Google Web Toolkit was chosen with Hibernate and Gilead connecting a MySQL database management system. Image and signal data integration and processing is supported by Apache Commons FileUpload-Library and ImageJ-based Java code, respectively. As a proof of concept, the framework is instantiated to the German Calciphylaxis Registry. The framework is composed of five mandatory core modules: (1) Data Core, (2) EDC, (3) Access Control, (4) Audit Trail, and (5) Terminology as well as six optional modules: (6) Binary Large Object (BLOB), (7) BLOB Analysis, (8) Standard Operation Procedure, (9) Communication, (10) Pseudonymization, and (11) Biorepository. Modules 1-7 are implemented in the German Calciphylaxis Registry. The proposed RDR framework is easily instantiated and directly integrates image management and analysis. As open source software, it may assist improved data collection and analysis of rare diseases in near future.

    Recent studies have highlighted the potential of jet substructure techniques to identify the hadronic decays of boosted heavy particles. These studies all rely upon the assumption that the internal substructure of jets generated by QCD radiation is well understood. In this article, this assumption is tested on an inclusive sample of jets recorded with the ATLAS detector in 2010, which corresponds to 35 pb$^{-1}$ of pp collisions delivered by the LHC at $\\sqrt{s}$ = 7 TeV. In a subsample of events with single pp collisions, measurementes corrected for detector efficiency and resolution are presented with full systematic uncertainties. Jet invariant mass, kt splitting scales and n-subjettiness variables are presented for anti-$k_t$ R = 1.0 jets and Cambridge-Aachen R = 1.2 jets. Jet invariant-mass spectra for Cambridge-Aachen R = 1.2 jets after a splitting and filtering procedure are also presented. Leading-order parton-shower Monte Carlo predictions for these variables are found to be broadly in agreement with...

    The textile industry is an energy intensive branch of industry. Increasing energy costs are a challenge for textile manufacturers as well as for the developers of textile production machines [1]. Air jet weaving is the most productive method to produce woven fabrics. However, air-jet weaving machines have a significantly higher level of energy consumption compared to other weaving machines. Approximately 80% of compressed air is consumed by the relay nozzles. Therefore, there are different approaches to reduce the consumption of compressed air and to increase the energy efficiency of air-jet looms [2] At the Institut für Textiltechnik der RWTH Aachen University, Aachen new relay nozzle concepts have been developed. Based on Computational Fluid Dynamics (CFD) the concepts were further developed with the result of an energy-efficient relay nozzle concept. The simulations have shown the potential energy savings up to 60 % compared to conventional relay nozzles. Furthermore, practical validations of these simulation results were done. The velocity, stagnation pressure and volume flow were measured in the reed canal. The optimal position regarding the injection angle and high, as well as the distance between two relay nozzles were identified with the results of the measurements. In addition, the relay nozzles were tested in the industrial environment. These tests have shown a low error rate which is comparable conventional relay nozzle concepts. Furthermore, exergy savings up to 49% has been measured.

    Preparing medical students for the takeover or the start-up of a medical practice is an important challenge in Germany today. Therefore, this paper presents a computer-aided serious game (eMedOffice) developed and currently in use at the RWTH Aachen University Medical School. The game is part of the attempt to teach medical students the organizational and conceptual basics of the medical practice of a general practitioner in a problem-based learning environment. This paper introduces methods and concepts used to develop the serious game and describes the results of an evaluation of the game's application in curricular courses at the Medical School. Results of the conducted evaluation gave evidence of a positive learning effect of the serious game. Educational supervisors observed strong collaboration among the players inspired by the competitive gaming aspects. In addition, an increase in willingness to learn and the exploration of new self-invented ideas were observed and valuable proposals for further prospective enhancements were elicited. A statistical analysis of the results of an evaluation provided a clear indication of the positive learning effect of the game. A usability questionnaire survey revealed a very good overall score of 4.07 (5=best, 1=worst). We consider web-based, collaborative serious games to be a promising means of improving medical education. The insights gained by the implementation of eMedOffice will promote the future development of more effective serious games for integration into curricular courses of the RWTH Aachen University Medical School.

    Studies concerning welding fume-related adverse health effects in welders are hampered by the heterogeneity of workplace situations, resulting in complex and non-standardized exposure conditions. In order to carry out welding fume exposure studies under controlled and standardized conditions, the Aachen Workplace Simulation Laboratory was developed. This laboratory consists of an emission room, in which welding fume is produced, and an exposure room in which human subjects are exposed to these fumes. Both rooms are connected by a ventilation system which allows the welding fume concentration to be regulated. Particle mass concentration was measured with a TEOM microbalance and the particle number-size distribution using a Grimm SMPS device. In a study, which is the subject of this paper, it has been shown that welding fume concentration can easily be regulated between 1 and about 3 mg m(-3). The chosen concentration can be kept constant for more than 8 h. However, transport of the particles from the emission room into the exposure room leads to a change in particle size distribution, which is probably due to coagulation of the fraction of smallest particles. The Aachen Workplace Simulation Laboratory is suitable for controlled exposure studies with human subjects.

    Under the provisions of Interagency Agreement DOE 1938-B090-A1 between the US Department of Energy (DOE) and the US Army Europe (USAREUR), Martin Marietta Energy Systems, Inc., is providing technical assistance to USAREUR in the areas of computer science, information engineering, energy studies, and engineering and systems development. One of the initial projects authorized under this interagency agreement is the evaluation of utility and energy monitoring and control systems (UEMCSs) installed at selected US Army installations in Europe. This report is an evaluation of the overall energy-conservation effectiveness and use of the UEMCS at the 409th Base Support Battalion located in Grafenwoehr, Germany. The 409th Base Support Battalion is a large USAREUR military training facility that comprises a large training area, leased housing, the main post area, and the camp areas that include Camps Aachen, Algier, Normandy, Cheb, and Kasserine. All of these facilities are consumers of electrical and thermal energy. However, only buildings and facilities in the main post area and Camps Aachen, Algier, and Normandy are under the control of the UEMCS. The focus of this evaluation report is on these specific areas. Recommendations to further increase energy and cost savings and to improve operation of the UEMCS are proposed.

    Within the framework of an R and D project sponsored by the Deutsche Bundesstiftung Umwelt, cleaning of process and excess water from organic waste fermentation plants was studied at the Institute for Siedlungswasserwirtschaft of Aachen Technical University RWTH. The focus in studying these waste waters was on the adaptation and optimization of the ZenoGem {sup trademark} process - a biological cleaning technique with an integrated microfiltration membrane. The use of this technology had the following objectives: to safeguard compliance with the limiting values for direct or indirect discharge of excess water and to reduce the heavy metal freight of circulating process water reentering the fermentation process for mashing raw organic waste. Thus the pollutant content of the fermentation residue was to be cut down. (orig.) [German] Im Rahmen eines von der Deutschen Bundesstiftung Umwelt gefoerderten Forschungs- und Entwicklungsvorhabens wurde am Institut fuer Siedlungswasserwirtschaft der RWTH Aachen die Prozess- und Ueberschusswasserreinigung von Bioabfallvergaerungsanlagen untersucht. Dabei stellte die Adaption und Optimierung des ZenoGem {sup trademark} -Verfahrens - ein biologisches Reinigungsverfahren mit integrierter Mikrofiltrationsmembran - fuer diese Abwaesser den Untersuchungsschwerpunkt dar. Ziel war es, mit dieser Technologie zum einen die Grenzwerte fuer eine direkte oder indirekte Einleitung des Ueberschusswassers zu gewaehrleisten und zum anderen die zirkulierenden Prozesswaesser, die in den Vergaerungsprozess zum Anmaischen der Roh-Bioabfaelle zurueckgefuehrt werden, an Schwermetallen zu entfrachten. Hierdurch sollte eine Schadstoffreduktion im Gaerreststoff erzielt werden. (orig.)

    Full Text Available Although the EU has introduced various policies to foster student mobility within Europe, it remains a ‘stylized fact’ that the majority of student mobility is geared towards the US. Many students who choose to complete (part of their higher education in the US may choose to stay there upon graduation, constituting part of the ‘brain drain’. However, if a considerable part of these students return to Europe, bringing with them additional human and social capital, they may benefit the European economy. In this context, we study the migration behavior of a sample of European economics students who obtained a PhD in the US. First, we find a high stay rate : 64 % are currently working in the US, whereas only 24 % move back to their home country and an additional 10 % move to another European country. However, there are substantial differences in remigration patterns among different European countries and regions. The majority of returnees return immediately upon completion of their PhD degree, however, there is still considerable return migration of initial stayers up until the point where they likely receive tenure. Within Europe, the UK is the preferred destination for PhD holders who do not return to their home country. Finally, increasing funding for European students to pursue a PhD in the US may boost return rates, as PhD holders who were funded by their home country are more likely to return.Hoewel de EU verschillende beleidsmaatregelen geïntroduceerd heeft om studentenmobiliteit binnen Europa te bevorderen, blijft het een algemeen aanvaard feit dat het merendeel van de studentenmobiliteit de VS als bestemming heeft. Veel studenten die (een gedeelte van hun hogere studies in de VS afronden hebben de mogelijkheid om na hun afstuderen in de VS te blijven, en zo een deel van de ‘brain drain’ te vormen. Indien echter een groot aantal van hen terugkeren naar Europa, en daarbij additioneel menselijk en sociaal kapitaal met zich

    Theorie und Praxis, die mangelnde didaktische Ausbildung der akademischen Lehrer, die fehlende Wertschätzung einer guten Lehre, zu große Gruppen, fehlende fachliche und persönliche Beziehungen zwischen Lehrern und Studierenden, und immer noch die Triade, die von den Ärzten der Unikliniken verlangt ihre Facharztweiterbildung, Grundlagenforschung und den Studentenunterricht simultan zu leisten. Gleichzeitig wird die Erfahrung und Kompetenz der großen Zahl von erfahrenen, habilitierten Hochschuldozenten, die die Universität verlassen haben, nicht optimal genutzt.Pilotprojekt: Seit 1998 führen wir in unserer Gemeinschaftspraxis zweimal pro Semester ein Blockseminar für Studierende der klinischen Semester durch. Die maximale Gruppenstärke beträgt 3 Studenten pro Dozent. Die Unterrichtsinhalte umfassen die Anämiediagnostik, Differentialdiagnose der Leukozytopenie, Leukozytose, Thrombozytose, Thrombozytopenie, Diagnostik und Systematik der Leukämien und Lymphome, Morphologieunterricht sowie die Grundprinzipien der ärztlichen Gesprächsführung. Methodisch steht das problemorientierte Lernen unter Verwendung von Patientenakten, einem Videomikroskop sowie eine von uns entwickelte Differentialdiagnose CD im Mittelpunkt.Ergebnisse: Bisher haben 320 Studenten an unseren Seminaren teilgenommen. Die systematische Evaluation des Unterrichtes durch die Studenten ergibt Bestnoten für Praxisrelevanz, Unterrichtsatmosphäre, Didaktik und Effektivität. Einblicke in die Möglichkeiten des ärztlichen Arbeitens im Niedergelassenen Bereich erweitern den studentischen Erfahrungshorizont.Schlussfolgerung: Der akademische Unterricht von Medizinstudenten in einer Gemeinschaftspraxis ist auf hohem Qualitätsniveau möglich. Durch dieses Lehrmodell wird externen Hochschuldozenten der Unterricht erleichtert, gleichzeitig kann die Universität personell und finanziell entlastet werden.

    Full Text Available Norsk ingeniørutdanning har blitt kritisert for å være for teoretisk. Næringslivets hovedorganisasjon (NHO m.fl. startet derfor prosjektet «Lærlingeordning i høyere utdannelse». Høgskolen i Bergen dro nytte av erfaringene derfra, og i 2007 – da bachelorstudiet i undervannsteknologi startet – var forutsetningen at studiet skulle ha stor praksisandel og mye kontakt med lokalt næringsliv. Studiet har blitt Norges mest etterspurte treårige ingeniørstudium. Frafallet har vært lavere enn ved andre ingeniørstudier. Studiet har inneholdt flere praksisformer, hvorav bacheloroppgave i bedrift, ingeniørpraksis og verkstedpraksis ble regnet som de mest utbytterike ut fra svar i spørreundersøkelsene. 72 % av studentene anså praksis som en viktig årsak til at de søkte. Faglig interesse og utsikt til gode jobber var dog viktigst. 71 % av studentene opplevde at praksis underveis ville gjøre dem til bedre ingeniører, mens 55 % mente det hadde innvirkning på at de fullførte studiet. Praksisbedriftene har tjent ved bedret rekruttering, de største opptil 0,7 ansatt per praksisplass. Praksisorganisering er krevende, og kvalitetssikring og oppfølging er viktig for å få et godt resultat. Bedriftsnettverk er gode støttespillere, men skolen må også avsette nok ressurser til arbeidet. Siden skader kan skje i industrien, må forsikringsordninger av studenter i praksis settes på den politiske agendaen slik at regelverket kan endres. Summary Norwegian engineering studies has been criticized of being too theoretical. Bergen University College used experiences from the project “Apprenticeship in higher education” when starting the engineering program in Subsea technology in 2007. Much practice and contact with local industry was requested. The program has become popular and dropout is lower than in comparable programs. Student surveys revealed the most rewarding practice to be a company-based Bachelor thesis, engineer internships and

    Full Text Available Utgangspunktet for studien er at naturvitenskaplige fag, særlig anatomi, fysiologi og biokjemi (AFB, oppleves som vanskelig for sykepleierstudentene. Hensikten var å undersøke om læringsverktøyet e-læring, i form av nettester, kan være et effektivt virkemiddel til innlæring av og påvirke læringsutbyttet i AFB.Førsteårsstudentene i bachelorutdanningen i sykepleie ved Høgskolen i Akershus fikk et spørreskjema med 23 spørsmål som ble besvart anonymt.Resultatet av studentundersøkelsen viste at nettoppgavene ble mye brukt, og at studentene mente de ga et godt læringsutbytte. Nettoppgaver med umiddelbar feedback gir stor studentaktivitet og «time-on-task». Testene kan tette hullet mellom det studentene forventes å kunne og det de faktisk kan, og egner seg til faktafag som m å pugges og forstås. E-læring kan gi god hjelp til studenters strukturering av tid, læringsstrategier og selvregulering.Læringsutbyttet av nettester diskuteres i lys av nytten av umiddelbar feedback i et pedagogisk perspektiv.AbstractThe starting point of the study is that the natural sciences, particularly anatomy, physiology and biochemistry (collectively known as APB, are often difficult subjects for nursing students. The aim was to investigate whether e-learning tools, in terms of web services, can be an effective educational tool and affect learning outcomes in APB.First year students in the Bachelor's degree program in nursing at Akershus University College of Applied Sciences received a questionnaire with 23 questions, which were answered anonymously.The results of the student survey showed that online tasks were widely used, and that students felt they resulted in good learning outcomes. Online training with immediate feedback shows great student activity and “time-on-task.” These tests can close the gap between what the students are expected to know and what they actually do, and is suitable for factual subjects requiring both memorization and

    CMS is the first large experiment of high-energy particle physics whose inner tracking system is exclusively instrumented with silicon detector modules. This tracker comprises 15 148 silicon strip modules enclosing the interaction point in 10-12 layers. The 1. Physikalisches Institut B of RWTH Aachen was deeply involved in the completion of the end caps of the tracking system. The institute played a leading role in the end cap design, produced virtually all support structures and several important electrical components, designed and built the laser alignment system of the tracker, performed system tests and finally integrated one of the two end caps in Aachen. This integration constitutes the central part of the present thesis work. The main focus was on the development of methods to recognise defects early in the integration process and to assert the detector's functionality. Characteristic quantities such as the detector noise or the optical gain of the readout chain were determined during integration as well as during a series of tests performed after transport of the end cap from Aachen to CERN. The procedures followed during the mechanical integration of the detector and during the commissioning of integrated sectors are explained, and the software packages developed for quality assurance are described. In addition, results of the detector readout are presented. During the integration phase, sub-structures of the end cap - named petals - were subjected to a reception test which has also been designed and operated as part of this thesis work. The test setup and software developed for the test are introduced and an account of the analysis of the recorded data is given. Before the end cap project entered the production phase, a final test beam experiment was performed in which the suitability of a system of two fully equipped petals for operation at the LHC was checked.

    In the context of the 'Climate' exhibition, an interactive strategic climate game was to be developed with the intention of making the subject attractive to juveniles, pupils and students. The complex interdependences within the Earth-Humans system were to be shown, along with the implications that action must always be taken in conditions of only partial knowledge, and that divergent interests must be considered on a global scale. (orig.) [German] Im Rahmen der Sonderausstellung 'Klima' soll ein interaktives strategisches Klimaspiel entwickelt werden. Die im klassischen Ausstellungsmedium schwer vermittelbaren Inhalte der Klimapolitik, der politischen und technischen Handlungsoptionen bei der Bewaeltigung des Klimawandels sollen mit dem Medium Computerspiel zeitgemaess und zielgruppengemaess (Zielgruppe Jugendliche, Schueler, Studenten) attraktiv umgesetzt werden. Das Spiel soll eine Ahnung von den komplexen Wechselbeziehungen des Systems Erde-Mensch vermitteln, bewusst machen, wie der Mensch schon heute am Steuer des 'Raumschiffes Erde' sitzt, vermitteln, dass unter den Bedingungen partiellen Wissens gehandelt werden muss und unterschiedliche Interessen auf der globalen Arena ausgehandelt werden muessen.

    Full Text Available Fremdsprachenkenntnisse sind heutzutage erforderlich, insbesondere in einem Land wie Slowenien. Nicht nur aufgrund dessen, dass man mit der slowenischen Sprache geographisch begrenzt ist, sondern da auch in der Mehrzahl der ausgeschriebenen Stellen Fremdsprachenkenntnisse erwünscht sind. Aus diesem Grund werden auch im tertiären Bildungssektor mindestens zwei berufsbezogene Fremdsprachen angeboten, von denen die Studenten eine wählen müssen. Und obwohl sich die Meisten für Englisch entscheiden, ist in den letzten Jahren ein zunehmendes Interesse an Deutschkursen zu verzeichnen. Ungeachtet dessen ist heutzutage ein gewisses Fundament an Englischkenntnissen praktisch unerlässlich, was auch beim Unterrichten des Faches Deutsch als Fremdsprache aufgefallen ist, wo in fast allen Kommunikationssituationen der Arbeitswelt, insbesondere aber in der Fachterminologie, ein zunehmender Einfluss der englischen auf die deutsche Sprache festzustellen ist. In diesem Beitrag wird der Gebrauch von Anglizismen in Lehrmaterialien zum Thema Luftfahrt untersucht, die an der Fakultät für Logistik beim DaF-Unterricht verwendet werden. Zu diesem Zweck werden zuerst die für den Unterricht relevanten Anglizismen aufgeführt und diskutiert. Im Anschluss erfolgen Implikationen für das Lehren und Erlernen der berufsbezogenen Fremdsprache.

    Full Text Available Dei siste tiåra er prega av ei multimodal vending som inneber at mange typar kommunikasjon går føre seg gjennom at fleire ulike uttrykksmåtar samverkar, slik som verbalspråk, bilete, lyd og materialitet. Endringane har ført til eit auka behov for kunnskap om korleis ein kan arbeide bevisst og kritisk med multimodale skapande prosessar. Denne artikkelen undersøkjer korleis element frå det teoretiske rammeverket sosialsemiotikk kan nyttast i arbeid med multimodale skapande prosessar og læreprosessar. Vi gjer greie for nokre erkjenningsteoretiske samanhengar mellom sosialsemiotikken og samtidas relasjonelle kunsthandverk, og på denne bakgrunnen utviklar vi nokre teoretiske omgrep som kan nyttast i multimodale skapande praksisar. Artikkelen viser vidare korleis omgrepa kan fungere i kunstprosjekt og didaktiske prosjekt. Eit hovudresultat er at omgrepa kan fungere bevisstgjerande og gi språk og artikulasjon undervegs i skapande prosessar, noko som vidare kan betre moglegheitene for kritisk tenking, etterprøvbar refleksjon og kommunikasjon både hjå forskaren, kunstnaren, læraren og studenten.

    The overall goal of COACh was to perform basic and applied research in the field of atmospheric and climate change. For this purpose a consortium of institutions in Germany (MPI-Chemistry in Mainz, MPI-Meteorology in Hamburg) and the Netherlands (IMAU, KNMI, CKO) was established. A major activity within COACh was the training and education of students during international summer schools. Beside that, individual projects related to atmospheric chemistry and global change are conducted. (orig.) [German] As uebergeordnete Ziel von COACh war es, grundlagen- und anwendungsorientierte Forschung zum globalen Wandel im Bereich der Klima- und Atmosphaerenforschung im Rahmen eines Deutsch-Niederlaendischen Konsortiums zu initiieren und zu koordinieren.

    Full Text Available Studien benytter resultater fra studentevaluering av tre kurs ved bachelorutdanningen i økonomi og administrasjon ved Høgskolen i Bergen (HiB til å undersøke eventuelle sammenhenger mellom kursomfang/vanskelighetsgrad, studentens egen innsats og deres vurdering av kurset. Hovedresultatet er at det er en positiv sammenheng mellom innsats og kursevaluering. Det er imidlertid ikke mulig å si noe om kausalitetsforhold – ytterligere forskning er nødvendig for å få bedre innsikt i disse sammenhengene. Summary The study is based on quantitative student evaluations of three undergraduate courses (Econ/Business from the Bergen University College. Students were asked to rate different aspects of the courses, as well as report their own effort, and how difficult and extensive they perceived the course to be. The main purpose of this study is to look into possible relations between these variables, in particular how students’ effort and their perception of the course as difficult or not influence their evaluation of the course. The results are somewhat surprising; it is particularly interesting that a positive correlation is found between effort and evaluation. Although a causal relationship has not been established, some possible implications of this finding are discussed, and some ideas for further research are proposed.

    2004-07-01

    The book addresses students of science and engineering, engineers and practicians in research and industry who are interested in temperature measurements and thermal processes in the temperature range between a few K and over 3200 K. For the first time ever, temperature sensors are classified on the basis of heat transport and heat transfer to the sensor as related to the technological aspects of sensor stress. This includes physical and materials-related fundamentals, materials selection, sensor design and optimisation, error analysis, as well as the analysis of economically relevant applications of electrical temperature measurement in thermal processes. [German] Dieses Buch wendet sich an Studenten der Natur- und Technikwissenschaften, Ingenieure und Hochschulabsolventen in der Forschung und Industrie, die sich mit Temperaturmessungen und thermischen Prozessen im Temperaturbereich von wenigen Kelvin bis zu ueber 3200 K befassen. Der neue Titel wird sich gegenueber bekannten Standards auf diesem Gebiet dadurch auszeichnen, dass eine Klassifizierung der Temperaturfuehler abhaengig vom Waermetransport und den Waermeuebergaengen zum Sensor in Verbindung mit den technologischen Aspekten zu den konkreten Beanspruchungen der Fuehler in der Anwendung vorgenommen wird. Dieser hohe Anspruch schliesst physikalische und werkstoffwissenschaftliche Grundlagen zur Systemloesung, der Werkstoffauswahl, zur Auslegung und Optimierung des Fuehlerdesigns und der notwendigen Fehlerbetrachtung ebenso ein, wie die Analyse volkswirtschaftlich bedeutsamer Anwendungen der elektrischen Temperaturmesstechnik in thermischen Prozessen.

    2005-01-01

    Full Text Available All astronauts often feel uncomfortable during first encounter microgravity because of fluid shifts from the lower extremities to the head caused by weightlessness. Parabolic flights offer a great possibility for research of this phenomenon under “zero gravity”. With a combination of the optoelectronic sensor concepts PPG and PPGI and an ultrasound device it should be possible to measure all relevant parameters for description and further explanation of rapid fluid shifts along the body axis in humans during parabolic flights. A research team of the RWTH Aachen University and the Charité University Berlin will participate in the 7th German Parabolic Flight Campaign in September 2005 and perform the experiments under micro gravitation. A combination of used non-invasive strategies will reveal new insights into the human hemodynamics under microgravity conditions. The optoelectronic part of this interdisciplinary research experiment, details from the measuring setup, data collecting and post processing will be discussed.

  13. Climatology and forest decay - stresses caused by dry periods

    International Nuclear Information System (INIS)

    Havlik, D.

    1991-01-01

    In the discussion of forest decline in the Eighties, stresses due to dry weather is often named as a secondary cause. The concept of 'climatological dry periods' is introduced in this article and applied to records for the Basel and Aachen regions. The time distribution of dry periods of different length and different water deficiency (40 mm, 60 mm, 100 mm) is analyzed. In the case of the Basel data, the dry periods are related to the 'forest damage caused by draught' recorded for the Basel region since 1930. The results support the theory that increasingly larger and more frequent dry periods with water shortage have contributed significantly to forest damage in the last 15 years. Apart from the 'dry stress' itself, also the enhanced production of photooxidants is a damaging mechanism. (orig.) [de

  14. Lesion correlates of patholinguistic profiles in chronic aphasia: comparisons of syndrome-, modality- and symptom-level assessment.

    One way to investigate the neuronal underpinnings of language competence is to correlate patholinguistic profiles of aphasic patients to corresponding lesion sites. Constituting the beginnings of aphasiology and neurolinguistics over a century ago, this approach has been revived and refined in the past decade by statistical approaches mapping continuous variables (providing metrics that are not simply categorical) on voxel-wise lesion information (voxel-based lesion-symptom mapping). Here we investigate whether and how voxel-based lesion-symptom mapping allows us to delineate specific lesion patterns for differentially fine-grained clinical classifications. The latter encompass 'classical' syndrome-based approaches (e.g. Broca's aphasia), more symptom-oriented descriptions (e.g. agrammatism) and further refinement to linguistic sub-functions (e.g. lexico-semantic deficits for inanimate versus animate items). From a large database of patients treated for aphasia of different aetiologies (n = 1167) a carefully selected group of 102 first ever ischaemic stroke patients with chronic aphasia (∅ 12 months) were included in a VLSM analysis. Specifically, we investigated how performance in the Aachen Aphasia Test-the standard clinical test battery for chronic aphasia in German-relates to distinct brain lesions. The Aachen Aphasia Test evaluates aphasia on different levels: a non-parametric discriminant procedure yields probabilities for the allocation to one of the four 'standard' syndromes (Broca, Wernicke, global and amnestic aphasia), whereas standardized subtests target linguistic modalities (e.g. repetition), or even more specific symptoms (e.g. phoneme repetition). Because some subtests of the Aachen Aphasia Test (e.g. for the linguistic level of lexico-semantics) rely on rather coarse and heterogeneous test items we complemented the analysis with a number of more detailed clinically used tests in selected mostly mildly affected subgroups of patients.

Reciprocal interconnections between firms of different clusters shaped the region and created economic dynamics. Investments transgressed......The economic transition characterizing the process of European industrialization in the 19th century was concentrated on regions rather than on states. In the first half of the 19th century, the region of Aachen (in the west of Prussia) pioneered on the territory of the German states and developed...... the boundaries of single industries and new industries emerged. One important feature of the regional production system was cross-sectional knowledge transfer; a second was institutions supportive to this process....

    The Global Continuous Miner and Bolter Miner Census 2008 conducted by the Excavation and Mining Equipment Group (BGMR), RWTH Aachen, identified globally the 1,400 CM production units and about 200 Bolter Miners are mainly employed in coal mining operations. The study identified a number of relevant trends of interest to both mining companies as well as original equipment manufacturers (OEM). E.g. new markets like China, India or Russia are not developing as quickly as expected, the large CM and BM nations like US, South Africa and Australia will remain saturated and the annual replacement rate of new machines will stabilize at some 160 units. Other key findings highlight the growing importance of after sales services and a stronger focus on automation, as well as, aspects of Health, Safety and Environment (HSE). (orig.)

    2015-09-01

    Full Text Available State-of-the-art lung support systems are limited to short time application because of a lack of long term hemocompatibility and protein absorption on the membrane surfaces. In a highly interdisciplinary project at RWTH Aachen University a biohybrid lung assist system with endothelialised gas exchange flat membranes is developed to improve long term compatibility of oxygenators. To increase the gas exchange performance of flat membranes hollows are imprinted in the membrane surfaces. This approach is based on the research of B. J. Bell-house et al. [1], who discovered this effect, now known as Bellhouse-effect, around 1960. In this paper a processes to manufacture membrane assemblies for oxygenation with imprinted hollows on the flat membrane surfaces is reviewed.

  19. Measurement of turbulent wall shear-stress using micro-pillars

    International Nuclear Information System (INIS)

    Gnanamanickam, E P; Sullivan, J P; Nottebrock, B; Große, S; Schröder, W

    2013-01-01

    In experimental fluid mechanics, measuring spatially and temporally resolved wall shear-stress (WSS) has proved a challenging problem. The micro-pillar shear-stress sensor (MPS3) has been developed with the goal of filling this gap in measurement techniques. The MPS3 comprises an array of flexible micro-pillars flush mounted on the wall of a wall-bounded flow field. The deflection of these micro-pillars in the presence of a shear field is a direct measure of the WSS. This paper presents the MPS3 development work carried out by RWTH Aachen University and Purdue University. The sensor concept, static and dynamic characterization and data reduction issues are discussed. Also presented are demonstrative experiments where the MPS3 was used to measure the WSS in both water and air. The salient features of the measurement technique, sensor development issues, current capabilities and areas for improvement are highlighted. (paper)

  20. 8th International Symposium on Unsteady Aerodynamics and Aeroelasticity of Turbomachines

    CERN Document Server

    1998-01-01

    Twenty-one years have passed since the first symposium in this series was held in Paris (1976). Since then there have been meetings in Lausanne (1980), Cambridge (1984), Aachen (1987), Beijing (1989), Notre Dame (1991) and Fukuoka (1994). During this period a tremendous development in the field of unsteady aerodynamics and aeroelasticity in turbomachines has taken place. As steady-state flow conditions become better known, and as blades in the turbomachine are constantly pushed towards lower weight, and higher load and efficiency, the importance of unsteady phenomena appear more clearly. th The 8 Symposium was, as the previous ones, of high quality. Furthermore, it presented the audience with the latest developments in experimental, numerical and theoretical research. More papers than ever before were submitted to the conference. As the organising committee wanted to preserve the uniqueness of the symposium by having single sessions, and thus mingle speakers and audience with different backgrounds in this int...

  1. Theory of Digital Natives in the Light of Current and Future E-Learning Concepts

    Directory of Open Access Journals (Sweden)

    Bodo von der Heiden

    2011-06-01

    Full Text Available The digital generation has many names: Net Generation, Generation@ or Digital Natives. The meaning behind these terms is, that the current generation of students is digitally and media literate, technology-savvy and are able to use other learning approaches than former generations. But these topics are discussed controversial and even the cause-effect-relationship is not as clear as it seems. Did the digital generation really have other learning approaches, or do they have only the possibility to live other learning modes? Against this background this article tries to shed some light on this debate. Therefore we use current and future projects performed at RWTH Aachen University to illustrate the relevance, value and significance due to the theory of the digital natives.

    Experiment R606 (Aachen, CERN, Harvard, Munich, Northwestern, Riverside)installed in the specially constructed pit at intersection 6. It was designed to investigate production of new particles in the fragmentation and diffraction regions. Use was made of a toroidal field provided by 12 flat copper coils, seen here as the rays of a wheel; in the free spaces between coils are housed Cerenkov counters. These counters, together with calorimetric shower detectors, located behind the magnet, provide separation of electrons from hadrons. The momenta of particles going through the system are measured with two sets of three drift chambers, two in front of the magnet, one behind, whose size increases from 1.5 m for the one seen in the picture, to 5 m for the one on the back. On the right the thin- walled cylindrical vacuum chamber.

  4. Radioiodine therapy in veterinary medicine: treatment of hyperthyroidism in a cat

    1999-01-01

    A nine-year-old cat with symptoms of a distinct hyperthyroidism was presented at the University Hospital of the RWTH Aachen. The clinical symptoms as well as the diagnostic procedures performed at the hospital confirmed the diagnosis. After five weeks of thyreostatic medication a regular metabolism of the thyroid gland was established, followed by a radioiodine therapy with 70.3 MBq 131-iodine. Subsequently, the cat was hospitalized for two days before it could be released in good condition. Six weeks after treatment the former drastically reduced weight of the cat recovered to near normal. Even though the chemical analysis detected a discrete hyperthyroidism, clinical symptoms were no longer prominent. Three months after treatment, the final examination showed a regular metabolism of the thyroid gland without a specific thyroidal medication. The presented case illustrates that radioiodine therapy is a safe and efficient treatment of thyroidal dysfunctions in veterinary medicine. (orig.) [de

    A vast increase of wind turbines (WT) contribution in the modern electrical grids have led to the development of grid connection requirements. In contrast to the conventional test method, testing power-electronics converters for WT using a grid emulator at Center for Wind Power Drives (CWD) RWTH Aachen University offers more flexibility for conducting test scenarios. Further analysis on the performance of the device under test (DUT) is however required when testing with grid emulator since the characteristic of the grid emulator might influence the performance of the DUT. This paper focuses on the performance analysis of the DUT when tested using grid emulator. Beside the issue regarding the current harmonics, the performance during Fault Ride-Through (FRT) is discussed in detail. A power hardware in the loop setup is an attractive solution to conduct a comprehensive study on the interaction between the power-electronics converters and the electrical grids. (paper)

    Sonnenschein, Lars

    2011-01-01

    The drift velocity in drift tubes of the CMS muon chambers is a key parameter for the muon track reconstruction and trigger. It needs to be monitored precisely in order to detect any deviation from its nominal value. A change in absolute pressure, a variation of the gas admixture or a contamination of the chamber gas by air affect the drift velocity. Furthermore, the temperature and magnetic field influence its value. First data, taken with a dedicated Velocity Drift Chamber (VDC) built by RWTH Aachen IIIA are presented. Another important parameter to be monitored is the pressure inside the muon drift tube chambers. The differential pressure must not exceed a certain value and the absolute pressure has to be kept slightly above ambient pressure to prevent air from entering into the muon drift tube chambers in case of a leak. Latest drift velocity monitoring results are discussed.

    Bachelor of physics lectures on ‘Particle Physics and Astrophysics’ were complemented by exercises related to data analysis and data interpretation at the RWTH Aachen University recently. The students performed these exercises using the internet platform VISPA, which provides a development environment for physics data analyses. We describe the platform and its application within the physics course, and present the results of a student survey. The students’ acceptance of the learning project was positive. The level of acceptance was related to their individual preference for learning with a computer. Furthermore, students with good programming skills favour working individually, while students who attribute themselves as having low programming abilities favour working in teams. The students appreciated approaching actual research through the data analysis tasks. (paper)

  10. Why Did Early Industrial Capitalists Suggest Minimum Wages and Social Insurance?

    DEFF Research Database (Denmark)

    Reckendrees, Alfred

    for the world markets, the industrialists aimed at stabilizing the social environment and reconciling labour with the capitalist society. Their motivation, however, was not based on philanthropy; it was guided by economic aims and collective selfinterest. Analysing ‘social policy’ as a capitalist aim, the paper...... of Aachen (Prussian Rhineprovince) suggested to implement collective labour rules regulating working hours and wages. In the 1860s – 20 years before Bismarck – they proposed a mandatory pension system with equal contributions of employers and employees; they suggested labour conflict resolution by joint...... arbitration panels of employers and labour representatives. The proposals did not gain support from the Prussian ministries arguing collective agreements would violate freedom of contracting. Entrepreneurs demanding social welfare and the Prussian state defending economic liberalism – this challenges...

    2010-01-01

    Silicon photomultipliers (SiPMs) are modern semiconductor based detectors that have the potential to replace conventional photomultiplier tubes (PMTs) in many fields of application. In the course of research and development for upgrades of the CMS detector their potential for usage in different components is evaluated. The paper at hand deals with the temperature dependency of SiPMs. Their dark current is an important operating parameter. His temperature dependency is investigated using current-voltage characteristics. Furthermore a method for obtaining temperature independent output pulses is presented. To unleash the full potential of the sensors one has to make use of customized electronics for the readout. Therefore a custom printed circuit board developed by the electronics departments of our institute (III. Physikalisches Institut B, RWTH Aachen University) is used in this thesis. Finally the results of measurements on two commercially available MPPC modules from Hamamatsu Photonics K. K. are presented.

    This thesis describes the software development for a VDC system designed at RWTH AachenUniversity. The development includes firmware, data acquisition and control software. The VDCsystem is a combination of different measurement instruments in order to characterize the gasof the CMS muon chambers at LHC. Monitoring the variation of the electrons drift speed inthe gas leads to a exact spatial resolution. This also improves the momentum resolution of thedetected muons and it allows a more precise analysis of the collision events.All programs which are required for a continuous operation, written by myself, are described andexplained here. Besides the development of the firmware for new hardware modules, software fordata acquisition and control was written.The aim of this work was to master the step from simple measurements with a VDC prototypeto simultaneous measurements with six VDCs.

  13. Legal claims against Belgian reactors?

    2016-01-01

    The Belgian reactors Tihange 2 and Doel 3 have been restarted in November 2015 after the problem of hydrogen flakes in the reactor pressure vessels had been investigated. The permission to restart has been the object both of critical statements by the German Federal Ministry of the Environment (BMUB) and of lawsuits filed with Belgian law courts by a group of German municipalities led by the city of Aachen and by the Land North-Rhine-Westphalia. According to a general principle of the law of nations, a state is not permitted to operate installations near its border, which cause significant environmental damage in a neighbouring state. However, it is not quite clear how this principle applies to the issue of potential accidents of nuclear power plants. According to the author, a tangible threat of an accident is required; mere doubts and concerns about the extent of safety margins are not sufficient.

    A web-based software model was developed as an example for data mining in aphasiology. It is used for educating medical and engineering students. It is based upon a database of 254 aphasic patients which contains the diagnosis of the aphasia type, profiles of an aphasia test battery (Aachen Aphasia...... Test), and some further clinical information. In addition, the cerebral lesion profiles of 147 of these cases were standardized by transferring the coordinates of the lesions to a 3D reference brain based upon the ACPC coordinate system. Two artificial neural networks were used to perform...... a classfication of the aphasia type. First, a coarse classification was achieved by using an assessment of spontaneous speech of the patient which produced correct results in 87% of the test cases. Data analysis tools were used to select four features of the 30 available test features to yield a more accurate...

    Invariant mass spectra for jets reconstructed using the anti-kt and Cambridge-Aachen algorithms are studied for different jet "grooming" techniques in data corresponding to an integrated luminosity of 5 inverse femtobarns, recorded with the CMS detector in proton-proton collisions at the LHC at a center-of-mass energy of 7 TeV. Leading-order QCD predictions for inclusive dijet and W/Z+jet production combined with parton-shower Monte Carlo models are found to agree overall with the data, and the agreement improves with the implementation of jet grooming methods used to distinguish merged jets of large transverse momentum from softer QCD gluon radiation.

    2017-10-01

    For the first time 3D structures can now be produced on large circular knitting machines. Till date, such structures could only be manufactured on flat knitting machines. Since large circular knitting machines operate much faster, this development increases the overall productivity of 3D knits. It thus opens up a totally new avenue for cost reduction for applications in sportswear, upholstery, aerospace and automotive industry. The following paper presents the state of the art regarding the realisation of three dimensional fabrics. In addition, current knitting technologies regarding three dimensional formations will be explained. Results of the pretrials explaining the change in knitted fabrics´ dimension, executed at the Institut für Textiltechnik of the RWTH Aachen University, will be presented. Finally, the description of the 3D knit prototype developed will be provided as a part of this paper.

  18. Fabrication of Complex Optical Components From Mold Design to Product

    2013-01-01

    High quality optical components for consumer products made of glass and plastic are mostly fabricated by replication. This highly developed production technology requires several consecutive, well-matched processing steps called a "process chain" covering all steps from mold design, advanced machining and coating of molds, up to the actual replication and final precision measurement of the quality of the optical components. Current market demands for leading edge optical applications require high precision and cost effective parts in large volumes. For meeting these demands it is necessary to develop high quality process chains and moreover, to crosslink all demands and interdependencies within these process chains. The Transregional Collaborative Research Center "Process chains for the replication of complex optical elements" at Bremen, Aachen and Stillwater worked extensively and thoroughly in this field from 2001 to 2012. This volume will present the latest scientific results for the complete process chain...

    On the basis of earlier experiments showing a differential deficit of aphasics in picture sorting and matching tasks, two experiments were conducted to test the conjecture of a specific deficit of aphasics in the analytical appraisal of individual features. Broca's and Wernicke's aphasics--according to clinical diagnoses and the Aachener Aphasie Test--were compared with patients having right-hemisphere lesions or left-hemisphere lesions without aphasia. Both groups of aphasics differed from the control groups in the sorting task, irrespective of the sorting criterion, but the differences were small. The picture matching task did not discriminate between groups. Obviously, the basic assumption has to be modified with respect to specific conditions of task requirements. The experimental literature is reviewed.

    The Aachener Aphasie Test (AAT) is the major German test for the diagnosis of aphasic disorders. The test is easy to use and is valid and reliable for the diagnosis of aphasia and its severity and to evaluate the recovery of the aphasic disorder after language rehabilitation. The AAT is, however, not sufficient to define cognitively sound logotherapeutic treatment. The use of tasks which are based on cognitive functional models allows the identification of specific processing levels that have been damaged by a cerebral lesion, and the definition of a focussed rehabilitation plan. In this paper, we will discuss the results of a cognitive neurolinguistic treatment in a patient who suffered of Broca's aphasia with agrammatism and phonological dyslexia.

    The 'Quality Assurance and Demolition Symposium, which has become a tradition established jointly by Applus RTD Deutschland GmbH (formerly compra GmbH) and Brenk Systemplanung GmbH, Aachen, was held also in 2008 with the focus on quality assurance and the demolition of nuclear facilities. The conference began with a series of lectures on knowledge and document management in general, and the use of document management systems in the nuclear field in particular. The evening lecture was presented by Axel Weis (Karlsruhe Research Center) on 'Competence Preservation in Nuclear Technology'. The 24 technical papers presented on the next 2 days of the symposium dealt with non-destructive materials testing and with special problems of radiation protection, demolition, and waste management. In 2009, the meeting will cover similar main topics and will again be held in an interesting environment, perhaps in combination with a tour of a demolition project. (orig.)

    Full Text Available Increasing traffic loads and changes in code provisions lead to deficits in shear and flexural capacity of many existing highway bridges. Therefore, a large number of structures are expected to require refurbishment and strengthening in the future. This projection is based on the current condition of many older road bridges. Different strengthening methods for bridges exist to extend their service life, all having specific advantages and disadvantages. By applying a thin layer of carbon textile-reinforced mortar (CTRM to bridge deck slabs and the webs of pre-stressed concrete bridges, the fatigue and ultimate strength of these members can be increased significantly. The CTRM layer is a combination of a corrosion resistant carbon fiber reinforced polymer (CFRP fabric and an efficient mortar. In this paper, the strengthening method and the experimental results obtained at RWTH Aachen University are presented.

    1995-01-01

    The idea of measuring dimuon in the ALICE detector is not new, since it already appeared in the Aachen Conference. In the meantime studies were aiming at the use of the two detectors of LHC p-p physics, CMS and ATLAS, already dedicated to dimuon measurement, for these same measurements in heavy ion collisions, whereas the detector dedicated to heavy ions physics at LHC, ALICE, was considering all the other observables. Recently, the interest for dimuon measurements in ALICE was renewed by demands from LHC committee, stiring the activities of a working group in the ALICE collaboration, also associated to a more recent move from new groups. In the following the author briefly describes the interest of measuring dimuons in heavy ion collisions, particularly in ALICE, then the experimental strategy and first estimates of the performances that could be reached with the proposed system

    The Scintillating Fiber Tracker, SciFi for short, will be the main new tracking detector in LHCb. It will provide better than 100 µm spatial resolution, and high rate capability and radiation hardness enabling a fast, 40 MHz, trigger rate with a capability to withstand 50 fb$^{-1}$ integrated luminosity, delivered by LHC, without a major performance degradation. The main active element of the tracker is a scintillating fiber ribbon with the SiPM readout. The ribbons consist of 6 layers of the 250 µm scintillating fibers Kuraray SCSF-78MJ, assembled by winding and bound together by the epoxy glue. NRC Kurchatov Institute, Moscow, together with the colleagues from ITEP, CERN, TU of Dortmund and RWTH of Aachen are developing dedicated production centers with the aim to reach by 2016 production rate one ribbon per day per center, necessary to supply more than 1300 fibre ribbons (mats) needed for the new LHCb tracker.

    1980-01-01

    Economy in use of silver and new methods of development motivated studies to find out whether electroradiographic systems are suitable for use in medical X-ray diagnosis. Two electroradiographic systems - the high-pressure ionography system and the lead-oxide/gas-layer system - are discussed in detail, with a description of the formation of the latent charge pattern. At the Philips research laboratories in Aachen a special investigation of the sensitivity and resolution of the two systems has been made. In the section on the development procedure (making the latent charge pattern visible) consideration is also given to the possibility of 'picture processing' and the composition of the developer. Finally, the advantages and disadvantages of electroradiographic methods are compared with those of conventional radiography with silver films. (Auth.)

    The CMS tracker will be equipped with 16,000 silicon microstrip detector modules covering a surface of approximately 220 m**2. For quality control, a compact and inexpensive DAQ system is needed to monitor the mass production in industry and in the CMS production centres. To meet these requirements a set-up called APV Readout Controller (ARC) system was developed and distributed among all collaborating institutes to perform full readout tests of hybrids and modules at each production step. The system consists of all necessary hardware components, C++ based readout software using LabVIEW **1 Lab VIEW is a product of National Instruments, Austin, USA. as graphical user interface and provides full database connection to track every single module component during the production phase. Two preseries of Tracker End Cap (TEC) silicon detector modules have been produced by the TEC community and tested with the ARC system at Aachen. The results of the second series are presented.

    The silicon strip tracker of the CMS experiment has been completed and inserted into the CMS detector in late 2007. The largest sub-system of the tracker is its end cap system, comprising two large end caps (TEC) each containing 3200 silicon strip modules. To ease construction, the end caps feature a modular design: groups of about 20 silicon modules are placed on sub-assemblies called petals and these self-contained elements are then mounted into the TEC support structures. Each end cap consists of 144 petals, and the insertion of these petals into the end cap structure is referred to as TEC integration. The two end caps were integrated independently in Aachen (TEC+) and at CERN (TEC--). This note deals with the integration of TEC+, describing procedures for end cap integration and for quality control during testing of integrated sections of the end cap and presenting results from the testing.

    This note describes the assembly and testing of the 292 petals built for the CMS Tracker End Caps from the beginning of 2005 until the summer of 2006. Due to the large number of petals to be assembled and the need to reach a throughput of 10 to 15 petals per week, a distributed integration approach was chosen. This integration was carried out by the following institutes: I. and III. Physikalisches Institut - RWTH Aachen University; IIHE, ULB \\& VUB Universities, Brussels; Hamburg University; IEKP, Karlsruhe University; FYNU, Louvain University; IPN, Lyon University; and IPHC, Strasbourg University. Despite the large number of petals which needed to be reworked to cope with a late-discovered module issue, the quality of the petals is excellent with less than 0.2\\% bad channels.

    The Centre for Learning and Knowledge Management and Department of Computer Science in Engineering of the Technical University Aachen has developed a truck driving simulator which combines a driving simulation as well as traffic flow calculations to the interactive Driving Simulator (InDriveS). In real-time the effects of the driver's behaviour on the surrounding traffic are considered and vice versa. The integrative part of InDriveS is a software-in-the-loop and hardware-in-the-loop development environment. By means of this tool, all phases of development (Analysis, Design, Modelling, Simulation, Implementation as well as Testing and Evaluation) of new vehicle technologies, e.g. Information and Assistance Systems, can be realised in consideration of the road traffic and the driver's behaviour.

  15. The Dynamics of Overlapping Clusters

    DEFF Research Database (Denmark)

    Reckendrees, Alfred

    The economic transition characterizing the process of European industrialization in the 19th century was concentrated on regions rather than on states. In the first half of the 19th century, the region of Aachen (in the west of Prussia) pioneered on the territory of the German states and developed...... to a powerful industrial region. The implementation and diffusion of the factory system and the economic impact of adapted and new institutions make the core of this paper. Reciprocal interconnections between firms of different clusters shaped the region and created economic dynamics. Investments transgressed...... the boundaries of single industries and new industries emerged. One important feature of the regional production system was cross-sectional knowledge transfer; a second was institutions supportive to this process....

    Invariant mass spectra for jets reconstructed using the anti-kt and Cambridge-Aachen algorithms are studied for different jet "grooming" techniques in data corresponding to an integrated luminosity of 5 inverse femtobarns, recorded with the CMS detector in proton-proton collisions at the LHC at a center-of-mass energy of 7 TeV. Leading-order QCD predictions for inclusive dijet and W/Z+jet production combined with parton-shower Monte Carlo models are found to agree overall with the data, and the agreement improves with the implementation of jet grooming methods used to distinguish merged jets of large transverse momentum from softer QCD gluon radiation.

  17. Integrative Production Technology for High-Wage Countries

    CERN Document Server

    2012-01-01

    Industrial production in high-wage countries like Germany is still at risk. Yet, there are many counter-examples in which producing companies dominate their competitors by not only compensating for their specific disadvantages in terms of factor costs (e.g. wages, energy, duties and taxes) but rather by minimising waste using synchronising integrativity as well as by obtaining superior adaptivity on alternating conditions. In order to respond to the issue of economic sustainability of industrial production in high-wage countries, the leading production engineering and material research scientists of RWTH Aachen University together with renowned companies have established the Cluster of Excellence “Integrative Production Technology for High-Wage Countries”. This compendium comprises the cluster’s scientific results as well as a selection of business and technology cases, in which these results have been successfully implemented into industrial practice in close cooperation with more than 30 companies of ...

    Semi-insulating GaAs detectors processed in Aachen using Freiberger compound material with low carbon content (FCM-LC) have been irradiated with protons (23 GeV) at eleven different fluences up to 6.3 x 10{sup 14} p/cm{sup 2} at room temperature. The detectors have been characterized in terms of macroscopic quantities like I-V characteristic curves and the signal response for incident minimum ionizing particles before and after irradiation. At the temperature of -8 C three other GaAs detectors have been irradiated with protons at fluences of about 6 x 10{sup 13} p/cm{sup 2}. After the irradiation they are warmed up at room temperature. The behaviour of the detectors before and after the warming up period has been studied. (orig.). 8 refs.

    Vital parameter monitoring of term and preterm infants during incubator care with self-adhesive electrodes or sensors directly positioned on the skin [e.g. photoplethysmography (PPG) for oxygen saturation or electrocardiography (ECG)] is an essential part of daily routine care in neonatal intensive care units. For various reasons, this kind of monitoring contains a lot of stress for the infants. Therefore, there is a need to measure vital parameters (for instance respiration, temperature, pulse, oxygen saturation) without mechanical or conductive contact. As a non-contact method of monitoring, we present an adapted version of camera-based photoplethysmography imaging (PPGI) according to neonatal requirements. Similar to classic PPG, the PPGI camera detects small temporal changes in the term and preterm infant's skin brightness due to the cardiovascular rhythm of dermal blood perfusion. We involved 10 preterm infants in a feasibility study [five males and five females; mean gestational age: 26 weeks (24-28 weeks); mean biological age: 35 days (8-41 days); mean weight at the time of investigation: 960 g (670-1290 g)]. The PPGI camera was placed directly above the incubators with the infant inside illuminated by an infrared light emitting diode (LED) array (850 nm). From each preterm infant, 5-min video sequences were recorded and analyzed post hoc. As the measurement scenario was kept as realistic as possible, the infants were not constrained in their movements in front of the camera. Movement intensities were assigned into five classes (1: no visible motion to 5: heavy struggling). PPGI was found to be significantly sensitive to movement artifacts. However, for movement classes 1-4, changes in blood perfusion according to the heart rate (HR) were recovered successfully (Pearson correlation: r=0.9759; r=0.765 if class 5 is included). The study was approved by the Ethics Committee of the Universal Hospital of the RWTH Aachen University, Aachen, Germany (EK 254/13).

  20. Is physician supervision of the capsaicin 8% patch administration procedure really necessary? An opinion from health care professionals

    Full Text Available Kai-Uwe Kern,1 Janice England,2 Andrea Roth-Daniek,3 Till Wagner3 1Institute for Pain Medicine/Pain Practice, Wiesbaden, Germany; 2Pain Medicine and Anaesthesia, The Christie National Health Service Foundation Trust, Manchester, UK; 3Pain Therapy and Palliative Care Department, Medizinisches Zentrum Städteregion Aachen, Aachen, Germany Abstract: Neuropathic pain is difficult to treat and can have a severe effect on quality of life. The capsaicin 8% patch is a novel treatment option that directly targets the source of peripheral neuropathic pain. It can provide pain relief for up to 12 weeks in patients with peripheral neuropathic pain. Treatment with the capsaicin 8% patch follows a clearly defined procedure, and patch application must be carried out by a physician or a health care professional under the supervision of a physician. Nonetheless, in our experience, nurses often take the lead role in capsaicin 8% patch application without the involvement of a physician. We believe that the nurse's key role is of benefit to the patients, as he or she may be better placed, because of time constraints and patient relationships, to support the patient through the application procedure than a physician. Moreover, a number of frequently prescribed drugs, including botulinum toxin and infliximab, can be administered by health care professionals without the requirement for physician supervision. Here we argue that current guidance should be amended to remove the requirement for physician supervision during application of the capsaicin 8% patch. Keywords: capsaicin, neuropathic pain, topical, health care professional, physician, nurse

The present study investigated whether the emotion regulation strategies, expressive suppression (ES and cognitive reappraisal (CR change in the course of cognitive behavior therapy (CBT of depressive inpatients. Furthermore, it also examined whether changes in CR and ES correlated with positive treatment outcomes.Methods: Forty-four inpatients from a psychotherapeutic hospital who suffered from a depressive disorder (mean age =36.4 years, standard deviation =13.4 years; 63.6% female filled in the Emotion Regulation Questionnaire and the Beck Depression Inventory at admission and discharge. To detect changes in emotion regulation, and depression across treatment, data were analyzed using multivariate analyses of variance (MANOVA for repeated measures, effect sizes, and Spearman correlations. A P-value of ≤0.05 was considered statistically significant.Results: Depression severity (F[1]=10.42, P=0.003; η2=0.22 and CR (F[1]=4.71, P=0.04; η2=0.11 changed significantly across CBT treatment. ES remained virtually stable. Post-treatment scores of CR were also positively correlated with reduction in depressive symptoms across treatment (ρ=0.30, P=0.05.Conclusion: The results suggest that CBT affects emotion regulation in depressive inpatients only for CR and that higher post-treatment scores in CR were related to greater reduction in depressive symptoms across treatment.Keywords: emotion regulation, depression, major depressive disorder, psychotherapy

  2. Preparation of a continuative brochure as supplement to the evaluation hand-out for the assessment of study results

    In 2013 the Federal Office for Radiation Protection gave the responsibility to the Department of History, Philosophy and Ethics of Medicine (Institut GTE Med) in Aachen for the project ''Creating a practical hand-out for the assessment of study results for employees of local governments'' (FM 8855). The manual serves as a practical way for the qualitative evaluation of texts for persons who deal with the topics Mobile Communication and Health (for example communities or government agencies) in their profession. The main objective of the manual is to aid users in performing a faster and more efficient evaluation of texts by answering the containing questions. This approach is purely functional and precludes the placement of deeper information. At this point the new project FM 8862 started by ''Creating a continuative brochure in addition to the hand-out for the assessment of study results''. It continued the previous project FM 8855 to further develop the information which was up to this point purely functional. The brochure presents the issues in an overall context and provides valuable background knowledge. As a result, possible users get in a more casual and clear manner a deeper understanding of the evaluating of texts. It should be possible for a user to better evaluate texts and by obtaining arguments, thus being better prepared to engage with interested Laymen in an objective discussion. The brochure was submitted together with the existing manual for a practical test, which was attended by 21 target group-specific subjects. The study tested in detail the intelligibility, clarity, applicability, and the support of the brochure. The feedback of the test participants were then used as basis for the final optimization of the brochure. Project participants belong to the Department of History, Philosophy and Ethics of Medicine and the Research Center for Bioelectromagnetic Interaction of the RWTH Aachen University (femu).

    Full Text Available Bart J Crielaard1, Steffen van der Wal1, Twan Lammers2, Huong Thu Le1, Wim E Hennink1, Raymond M Schiffelers1, Gert Storm1, Marcel HAM Fens11Department of Pharmaceutics, Utrecht Institute for Pharmaceutical Sciences, Utrecht University, Utrecht, The Netherlands; 2Department of Experimental Molecular Imaging, RWTH Aachen University, Aachen, Germany The first two authors contributed equally to this work. Abstract: Colchicinoids are very potent tubulin-binding compounds, which interfere with microtubule formation, giving them strong cytotoxic properties, such as cell mitosis inhibition and induction of microcytoskeleton depolymerization. While this makes them promising vascular disrupting agents (VDAs in cancer therapy, their dose-limiting toxicity has prevented any clinical application for this purpose. Therefore, colchicinoids are considered attractive lead molecules for the development of novel vascular disrupting nanomedicine. In a previous study, a polymeric colchicinoid prodrug that showed favorable hydrolysis characteristics at physiological conditions was developed. In the current study, this polymeric colchicinoid prodrug was evaluated in vitro and in vivo for its toxicity and vascular disrupting potential. Cell viability studies with human umbilical vein endothelial cells, as an in vitro measure for colchicine activity, reflected the degradation kinetics of the prodrug accordingly. Upon intravenous treatment, in vivo, of B16F10 melanoma-bearing mice with colchicine or with the polymeric colchicinoid prodrug, apparent vascular disruption and consequent tumor necrosis was observed for the prodrug but not for free colchicine at an equivalent dose. Moreover, a five-times-higher dose of the prodrug was well tolerated, indicating reduced toxicity. These findings demonstrate that the polymeric colchicinoid prodrug has a substantially improved efficacy/toxicity ratio compared with that of colchicine, making it a promising VDA for cancer therapy

    The pollution of air by nitrogen dioxide (NO{sub 2}) in cities is one of the central challenges of air pollution in Germany, in addition to the pollution of particulate matter (PM10). In cooperation with the British non-governmental organization ClientEarth, the German Environmental Aid (DUH) filed a lawsuit in November 2015 for exceeding air quality limits for NO{sub 2}. The cities of Stuttgart, Frankfurt, Duesseldorf, Essen, Gelsenkirchen, Aachen, Cologne and Bonn are affected. Here, citizens are constantly exposed to high air pollution. Because of the excess of the NO{sub 2} limits at all traffic-related measuring stations in Berlin, the DUH initiated legal steps and filed a lawsuit too in June 2016. With the lawsuits, DUH wants to promote the implementation of measures to reduce NO{sub 2} in Germany. [German] Die Belastung der Luft durch Stickstoffdioxid (NO{sub 2}) in Staedten ist neben der Belastung durch Feinstaub (PM10) eine der zentralen Herausforderungen der Luftreinhaltung in Deutschland. In Zusammenarbeit mit der britischen Nichtregierungsorganisation ClientEarth legte die Deutsche Umwelthilfe (DUH) im November 2015 Klage wegen Ueberschreitung der Luftqualitaetsgrenzwerte fuer NO{sub 2}ein. Betroffen sind die Staedte Stuttgart, Frankfurt, Duesseldorf, Essen, Gelsenkirchen, Aachen, Koeln und Bonn. Hier sind Buergerinnen und Buerger anhaltend zu hoher Luftverschmutzung ausgesetzt. Wegen Ueberschreitung der NO{sub 2}-Grenzwerte an allen verkehrsnahen Messstationen in Berlin hat die DUH im Juni 2016 auch hier rechtliche Schritte eingeleitet und Klage eingereicht. Mit den Klagen will die DUH die Umsetzung von Massnahmen zur NO{sub 2}-Reduktion in Deutschland voranbringen.

    Full Text Available Abstract Background Preparing medical students for the takeover or the start-up of a medical practice is an important challenge in Germany today. Therefore, this paper presents a computer-aided serious game (eMedOffice developed and currently in use at the RWTH Aachen University Medical School. The game is part of the attempt to teach medical students the organizational and conceptual basics of the medical practice of a general practitioner in a problem-based learning environment. This paper introduces methods and concepts used to develop the serious game and describes the results of an evaluation of the game's application in curricular courses at the Medical School. Results Results of the conducted evaluation gave evidence of a positive learning effect of the serious game. Educational supervisors observed strong collaboration among the players inspired by the competitive gaming aspects. In addition, an increase in willingness to learn and the exploration of new self-invented ideas were observed and valuable proposals for further prospective enhancements were elicited. A statistical analysis of the results of an evaluation provided a clear indication of the positive learning effect of the game. A usability questionnaire survey revealed a very good overall score of 4.07 (5=best, 1=worst. Conclusions We consider web-based, collaborative serious games to be a promising means of improving medical education. The insights gained by the implementation of eMedOffice will promote the future development of more effective serious games for integration into curricular courses of the RWTH Aachen University Medical School.

    Introduction Orthotopic liver transplantation (OLT) has emerged as the mainstay of treatment for end-stage liver disease. In an attempt to improve the availability of donor allografts and reduce waiting list mortality, graft acceptance criteria were extended increasingly over the decades. The use of extended criteria donor (ECD) allografts is associated with a higher incidence of primary graft non-function and/or delayed graft function. As such, several strategies have been developed aiming at reconditioning poor quality ECD liver allografts. Hypothermic oxygenated machine perfusion (HOPE) has been successfully tested in preclinical experiments and in few clinical series of donation after cardiac death OLT. Methods and analysis HOPE ECD-DBD is an investigator-initiated, open-label, phase-II, prospective multicentre randomised controlled trial on the effects of HOPE on ECD allografts in donation after brain death (DBD) OLT. Human whole organ liver grafts will be submitted to 1–2 hours of HOPE (n=23) via the portal vein before implantation and are going to be compared with a control group (n=23) of patients transplanted after conventional cold storage. Primary (peak and Δ peak alanine aminotransferase within 7 days) and secondary (aspartate aminotransferase, bilirubin and international normalised ratio, postoperative complications, early allograft dysfunction, duration of hospital and intensive care unit stay, 1-year patient and graft survival) endpoints will be analysed within a 12-month follow-up. Extent of ischaemia–reperfusion (I/R) injury will be assessed using liver tissue, perfusate, bile and serum samples taken during the perioperative phase of OLT. Ethics and dissemination The study was approved by the institutional review board of the RWTH Aachen University, Aachen, Germany (EK 049/17). The current paper represent the pre-results phase. First results are expected in 2018. Trial registration number NCT03124641. PMID:29018070

    In 2013 the Federal Office for Radiation Protection gave the responsibility to the Department of History, Philosophy and Ethics of Medicine (Institut GTE Med) in Aachen for the project ''Creating a practical hand-out for the assessment of study results for employees of local governments'' (FM 8855). The manual serves as a practical way for the qualitative evaluation of texts for persons who deal with the topics Mobile Communication and Health (for example communities or government agencies) in their profession. The main objective of the manual is to aid users in performing a faster and more efficient evaluation of texts by answering the containing questions. This approach is purely functional and precludes the placement of deeper information. At this point the new project FM 8862 started by ''Creating a continuative brochure in addition to the hand-out for the assessment of study results''. It continued the previous project FM 8855 to further develop the information which was up to this point purely functional. The brochure presents the issues in an overall context and provides valuable background knowledge. As a result, possible users get in a more casual and clear manner a deeper understanding of the evaluating of texts. It should be possible for a user to better evaluate texts and by obtaining arguments, thus being better prepared to engage with interested Laymen in an objective discussion. The brochure was submitted together with the existing manual for a practical test, which was attended by 21 target group-specific subjects. The study tested in detail the intelligibility, clarity, applicability, and the support of the brochure. The feedback of the test participants were then used as basis for the final optimization of the brochure. Project participants belong to the Department of History, Philosophy and Ethics of Medicine and the Research Center for Bioelectromagnetic Interaction of the RWTH Aachen University (femu).

    The Aachen Institute for Nuclear Training invited participants to the 3-day '2012 Repository Symposium - Final Storage in Germany' held in Bonn. The subtitle of the event, 'New Start - Ways and Consequences of the Site Selection Procedure,' expressed the organizers' summary that the Repository Finding Act currently under discussion did not give rise to any expectation of a repository for high-level radioactive waste before 2080. The symposium was attended by more than 120 persons from Germany and abroad. They discussed the basic elements of the site selection procedure and its consequences on the basis of the draft so far known to the public. While extensive public participation is envisaged for the stage of finding a repository, this does not apply to the draft legislation in the same way. The legal determinations are negotiated in a small circle by the political parties and the state governments. Michael Sailer (Oeko-Institut e.V.) holds that agreement on a repository finding act is urgent. Prof. Dr. Bruno Thomauske (RWTH Aachen) arrives at the conclusion mentioned above, that no repository for high-level radioactive waste can start operation before 2080 on the basis of the Repository Finding Act. Dr. Bettina Keienburg, attorney at law, in her paper drew attention to the points of dispute in the draft legislation with regard to changes in competency of public authorities. The draft law indicated a clear shift of competency for finding a repository from the Federal Office for Radiation Protection to a federal agency yet to be set up. Prof. Dr. Christoph Moench outlined the deficiencies of the draft legislation in matters of refinancing and the polluter-pays principle. Among the tentative solutions discussed it was above all the Swedish model which was acclaimed most widely. (orig.)

    The Nuclear Technology Conference organized annually by the Deutsches Atomforum (DAtF) e.V. and the Kerntechnische Gesellschaft (KTG) e.V. was held in Aachen on May 13-15, 1997. Approximately 1000 participants from seventeen countries met to exchange information with experts from industry, research, science, and politics. Unlike earlier events, this one was not disturbed by demonstrations. DAtF President Dr. Wilfried Steuer welcomed Joachim H. Witt, Chief Executive Officer of the city of Aachen, who expressed words of welcome on behalf of his city at the opening of the plenary day of the conference. Energy policy and global competition were the optics of the address by Dr. Norbert Lammert, Parliamentary Undersecretary of State with the German Federal Ministry of Economics. He advocated grasping the changes offered by expanding global markets by reforming the structures of the energy supply sector. The rank of nuclear power in European research policy was explained by Fabricio Caccia Dominioni as representative of the European Commission. The electricity utilities were represented by Dr. Dietmar Kuhnt, Chief Executive Officer of RWE AG, who spoke about the security of energy investments. A thoughtful analysis of Germany as an industrial location was presented by Professor Dr. Herbert Henzler of McKinsey and Company Inc. The President of the European Nuclear Society (ENS), Ger R. Kuepers, sketched the development of nuclear power in the Netherlands, combining national and European aspects and emphasizing, in particular, the important function of ENS. Uranium enrichment as an European project was subject of the report by Dr. Klaus Messer, Urenco Ltd. The General Manager of Tractabel Energy Engineering and Chairman of Belgatom, Guy Frederic, examined the economic viability of nuclear power, appealing to the audience to reduce capital costs by innovation without detracting from safety.

    Dimensioning of conventional activation systems in Germany as a rule relies on instruction sheet A131 of the Abwassertechnische Vereinigung or follows the Hochschulgruppen approach (HSG). They contain recommendations as to the size of the nitrification and denitrification zones, the amount of oxygen supplied and sludge production, and the size of the final sedimentation tank. For the use of sludge activation techniques by means of submerged membranes at municipal sewage treatment plant there so far do not exist any clues to dimensioning that make allowance for the modified boundary conditions. The present paper analyses instruction sheet A131 for its suitability as a basis in the dimensioning of sludge activation systems with submerged membranes at municipal sewage treatment plant. Then the dimensioning instructions are modified to suit the changed boundary conditions, and recommendations for the dimensioning of activation systems with submerged membranes on the basis of extensive studies carried out at the Institut fuer Siedlungswasserwirtschaft ISA of Aachen Technical University RWTH are given. (orig.) [German] Die Bemessung konventioneller Belebungsverfahren erfolgt in Deutschland i.d.R. auf der Grundlage des Arbeitsblatts A 131 der Abwassertechnischen Vereinigung bzw. nach dem Hochschulgruppenansatz (HSG).

Fuer den Einsatz von Membranbelebungsanlagen in kommunalen Klaeranlagen existieren bislang keine Bemessungshinweise, die den veraenderten Randbedingungen Rechnung tragen. Der vorliegende Beitrag analysiert das Arbeitsblatt A 131 in Hinsicht auf die Moeglichkeit zur Anwendung fuer die Bemessung von Membranbelebungsanlagen beim Einsatz zur kommunalen Abwasserreinigung.

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

    / 2005 nahmen 143 Medizinstudenten des interdisziplinären Blocks Innere Medizin an einem 12-Stationen-OSCE teil. Die Prüfungskonzeption erfolgte mit Hilfe eines Blueprint. Die Bestehensgrenze wurde mit einer modifizierten Angoff-Methode festgelegt, die Prüfungsleistung an einzelnen OSCE-Stationen von Experten mit Hilfe von eigens entwickelten Checklisten bestimmt. Ergebnisse: Der durchgeführte OSCE weist bezüglich der Reliabilität ein Cronbach alpha von 0,748 auf. Aufgrund der im Standard Setting festgelegten Bestehensgrenze erreichten 142 Studenten (99,3% Prozent das Prüfungsziel. Das Absolvieren der Prüfung am 1., 2. oder 3. Prüfungstag hatte keinen Einfluss auf die Benotung der studentischen Leistung. Diskussion: Der OSCE an der Medizinischen Universitätsklinik Heidelberg erweist sich als reliables und gerechtes Prüfungsinstrument. Auch wenn der OSCE ein ressourcen- und zeitaufwendiges Prüfungsinstrument darstellt, erweist er sich bei guter Planung und Organisation als eine selbst bei großen Studentenzahlen in einem Regelstudiengang realisierbare Prüfungsform, welche eine hohe Zufriedenheit bei Studenten und Prüfern hinterlässt.

Im Querschnitt der drei Studiensemester Zahnmedizin nahm die Anzahl der Studierenden mit auffälligen Werten ab. Studierende mit auffälligen Werten zeigten ein höheres Maß an dysfunktionalen Bewältigungsstrategien. Schlussfolgerung: Die Messwerte der Screening Instrumente ähneln der Untersuchungen anderer Autoren und unterstreichen die Bedeutung der Thematik. Aus Sicht der Prävention könnte sich bei Studenten der Zahnmedizin die Zeit vor dem ersten Patientenkontakt anbieten, um geeignete Bewältigungsstrategien zu vermitteln.

    Full Text Available Abstract Background Inter-professional learning (IPL and inter-professional practice (IPP are thought to be critical determinants of effective care, improved quality and safety and enhanced provider morale, yet few empirical studies have demonstrated this. Whole-of-system research is even less prevalent. We aim to provide a four year, multi-method, multi-collaborator action research program of IPL and IPP in defined, bounded health and education systems located in the Australian Capital Territory (ACT. The project is funded by the Australian Research Council under its industry Linkage Program. Methods/Design The program of research will examine in four inter-related, prospective studies, progress with IPL and IPP across tertiary education providers, professional education, regulatory and registration bodies, the ACT health system's streams of care activities and teams, units and wards of the provider facilities of the ACT health system. One key focus will be on push-pull mechanisms, ie, how the education sector creates student-enabled IPP and the health sector demands IPL-oriented practitioners. The studies will examine four research aims and meet 20 research project objectives in a comprehensive evaluation of ongoing progress with IPL and IPP. Discussion IPP and IPL are said to be cornerstones of health system reforms. We will measure progress across an entire health system and the clinical and professional education systems that feed into it. The value of multi-methods, partnership research and a bi-directional push-pull model of IPL and IPP will be tested. Widespread dissemination of results to practitioners, policymakers, managers and researchers will be a key project goal.

    Directory of Open Access Journals (Sweden)

    Marte Sørebø Gulliksen

    2013-01-01

    Full Text Available Artikkelen belyser og diskuterer læreres fagdidaktiske utvelgelseskompetanse i formgiving, kunst og håndverk. Det introduseres en antakelse om at det er mulig og nyttig å anlegge et valgperspektiv på didaktiske handlinger. Det pekes innledningsvis på en del utfordringer med lærerkunnskap, innhold, arbeidsformer og vurdering i faget, knyttet til de krav utfordringene stiller til lærerens utvelgelseskompetanse. Vygotskijs teorier omkring lånte erfaringer og bedømmelses­teorien til Kahneman & Tversky og Kahneman & Fredricks presenteres som et utvalgt teoretisk perspektiv. Det pekes på eksempler fra empiriske studier som har studert faglærerutdanningen i formgiving, kunst og håndverk. Fra disse presenteres og diskuteres situasjoner der valgproblematikk er avgjørende for studentenes læring og mestring av kommende yrkesutøvelse. Valgperspektivet viser seg å kunne gi en mulighet til å se nye potensielle strukturer i den komplekse situasjonen lærerutdanningen i formgiving, kunst og håndverk er: Perspektivet kunne belyse hvordan uklarhet omkring valgmuligheter førte til begrensning. Dessuten kunne det bidra til å problematisere sider av faglærerutdanningens spesialitet: Utfordringen det er å kombinere egen utøving i skapende arbeid og didaktisk utøving- og undervisningskompetanse. Det blir konkludert med at mer forskning er nødvendig, og det blir pekt på at et pågående forskningsprosjekt forhåpentligvis vil kunne bidra til dette, både ved å dokumentere den enkeltes erfaring og ved å studere kritisk om eksemplene i denne artikkelen kan sies å være aktuelle i flere situasjoner. Denne kunnskapen vil kunne styrke det forskningsbaserte grunnlaget for å utdanne lærere med nok utvelgelses­kompetanse til å gjøre gode valg.

    2014-12-01

    Full Text Available Concurrent (samtidig lærerutdanning møter en dobbelt utfordring: studentene skal lære et (eller flere fag, samtidig som de skal lære å lære bort fag. I Kunst og håndverk knyttes denne debatten ofte opp mot hvordan en i korte utdanningsenheter kan få nok faglig dybde i de ulike delene av faget. I artikkelens første del presenteres tidligere forskning på Kunst og håndverk. Et fagdidaktisk kunnskapsperspektiv trekkes opp i tilknytning til begrepet pedagogisk innholdskunnskap forstått som en re-forhandling av fagkunnskap og pedagogisk kunnskap (Shulman. Ut fra dette problematiseres fagets kvalifiseringsbredde og indre spenninger som en del av lærerutdanningens premiss. Det argumenteres for at en reduksjon av kvalifiserings­bredden ikke vil føre til redusert kompleksitet i undervisningen i faget. Artikkelens andre del foreslår begrepet beredskapskunnskap som en måte å håndtere fagets kompleksitet på: som et mulig grunnprinsipp for inn- og utvalg av arbeidsformer og innhold i utdanning i Kunst og håndverk. Diskusjonen knyttes til spørsmålet om hvordan lærerutdanning i Kunst og håndverk best kan ruste studenter til et langt liv som lærerprofesjonsutøvere i en fremtid vi ennå ikke vet hvordan ser ut. Artikkelen foreslår at beredskapskunnskap kan forstås som et nav i et prinsipp om livslang læring for lærere i Kunst og håndverk, og således som et overordnet mål for lærerutdanning generelt. 

  20. Hva med de gjenstridige dokumentene? Fagreferentrollen i spesialsamlinger

    Directory of Open Access Journals (Sweden)

    Solveig Greve

    2010-07-01

    Full Text Available Spesialsamlinger er samlinger av ”gjenstridige dokumenter”, dvs. dokumenter som er sjeldne, unika eller upubliserte og derfor ofte er fysisk bundet til eierinstitusjonen. Det er typisk at slike samlinger mangler moderne standarder for metadata og felles nasjonale katalogiseringsverktøy. Eierinstitusjonene har et kulturansvar for bevaring og tilgjengeliggjøring av disse dokumentene overfor en bredere allmennhet enn et fagbiblioteks ”primærbrukere”. Fagreferentens oppgaver vil være preget av dette. Bevaring, sikring og produksjon av digitale fulltekstdokumenter er sentralt. Det er også typisk for slike samlinger at en har en betydelig backlog. Det vil være fagreferentens oppgave å løfte fram ukjent kildemateriale, gjennom digitaliseringsprosjekter og forskning. Fagreferentens viktigste oppgaver vil da være mer rettet mot samlingspleie og formidling av egne samlinger og mindre fokus på andre institusjoners samlinger. Slik vil også undervisningen av studentene bli preget av arkivpresntasjon av innhold og forelesninger om teoretiske og praktiske forhold knyttet til å arbeide med spesielle materialtyper og mindre til utvikling av vanlig informasjonskompetanse. Denne situasjonen vil forandre seg hvis/når institusjonene blir enige om utvekslingsformater og mengden av digitale fulltekstdokumenter øker. Utfordringene for spesialsamlinger vil også være fagreferentenes utfordringer; I en stadig mer elektronisk verden, kan arbeidet med de fysiske samlingene lett bli marginalisert, selv om nettopp den tekniske utviklingen kunne løse mange problemer for de gjenstridige dokumentene. Men slik prioritering krever store ressurser, høy kompetanse, engasjement og politisk gjennomslagskraft. Kostnadene er høye, og konkurrerer budsjettmessig med galopperende elektroniske utgifter for hele biblioteket. Spesialsamlingenes fagreferenter kan bli en minoritetsstemme i bibliotekenes moderniseringsprosess, til skade for bibliotekenes totale faglige

    Full Text Available Denne artikkelen retter fokus mot studenters læring i praksis. Gjennom beskrivelsen av et pilotprosjekt i barnevernet, ønsker vi å synliggjøre hvordan bruken av studenter som medforskere kan bidra til økt kunnskapsutbytte samt en større forståelse av samspillet mellom teori og praksis. Samtidig har feltet sosialt arbeid behov for en modernisering. Denne artikkelen søker å vise at bruk av studenter som medforskere kan bidra til den nevnte modernisering. To spørsmål reises i artikkelen: Hvordan håndterer lærere og studenter utfordringer i forskningsprosessen i prosjekter hvor studenter deltar som medforskere? På hvilken måte kan praksisnær forskning bidra til å kaste lys over studentens læring? Abstract Students as research assistants – a pilot project in child welfare services.This article concerns students’ learning outcomes. Through a description of a pilot project in child welfare services, the aim is to demonstrate how the use of students as research assistants can contribute to increased knowledge outcomes and provide a better understanding of the interaction between theory and practice. At the same time, the field of social work needs a modernization. The article argues that the use of students as research assistants can contribute to the aforementioned modernization. Two issues are raised in the article: How to deal with teachers’ and students’ challenges in the research process in projects where students participate as research assistants? In what way can survivor research shed light on students’ learning outcomes?

    This practice oriented dictionary describes gas burners and gas engine technology as also required gases for operation of this appliances. Beside the presentation of this used fuel gases an their characteristica many gas appliances for cooking, heating and hot water treatment etc. are shown and described. Cogeneration is also a topic as reduction of pollutant emissions, gas exchangeability and possibilities to save energy. Many pictures and tables support the understanding of this complex technology. From the authors experiences of 34 years developing gas appliances can profit customer consultants of gas supplies, gas installation crews and constructors of heating systems. Last not least for students this practice oriented completion should be interesting in contrast to the mainly theoretical high school education. (GL) [German] Das vorliegende Buch spiegelt den aktuellen Stand der Gasanwendungstechnik auf dem haushaltlichen und gewerblichen Sektor. Als praxisorientiertes Nachschlagewerk beschreibt es sowohl die Gasbrenner- und Gasgeraetetechnik als auch die fuer den Betrieb dieser Gasgeraete erforderlichen Gase. Neben der Vorstellung der eingesetzten Brenngase und ihrer Kenngroessen wird eine Vielzahl unterschiedlicher Gasgeraete zum Heizen, Kochen, zur Warmwasserbereitung etc. beschrieben und erlaeutert. Darueber hinaus ist die Kraft-Waerme-Kopplung ebenso ein Thema wie die Reduzierung von Schadstoffemissionen, die Austauschbarkeit der Gase und die Moeglichkeiten der Energieeinsparung. Dem besseren Verstaendnis der komplexen Thematik dienen zahlreiche Bilder und Tabellen. Von den praktischen Erfahrungen, die der Autor in 35 Jahren auf dem Gebiet der gasanwendungstechnischen Entwicklung sammelte, profitieren in erster Linie Kundenberater der Gasversorgungsgesellschaften, Gasinstallateure und Heizungsbauer. Aber auch fuer Studenten wird diese praxisbezogene Ergaenzung des ueberwiegend theoretischen Hochschulunterrichts interessant sein. (orig.)

    Full Text Available Artikkelen drøfter problembasert læring og casemetodikk som metode for å oppfylle både vitenskapelige og profesjonsrettede læringsmål på et tidlig nivå i rettsstudiet. Især rettes spørsmålet mot hvordan man ivaretar av den teoretiske siden av utdanningen. I artikkelen drøftes anvendelsen av problembasert læring ved Universitetet i Bergen (UiB og Universitetet i Oslos (UiO metode som har noe likhet med casemetodikk. Artikkelen tar ikke mål av seg å gi noe klart svar på spørsmålet, men antyder at opplegget for jusstudenter i Oslo egner seg til å fremme elitetenkning ved å gi plass for de faglig sterkeste studentene til å forberede egen karriere fremfor å bidra til fellesskapets utvikling slik opplegget i Bergen ser ut til å stimulere. AbstractThe article discusses problem-based learning and case study methods in terms of their ability to meet both scientific and professional targeted learning objectives during early levels of the law study in Norway. In particular, the question is directed towards the safeguarding of the theoretical side of the education. The article is based on the application of problem-based learning at the University of Bergen and the method used at University of Oslo, which has some resemblance to the case study methodology. The article suggests that the methods at University of Oslo may promote elite thinking to a higher degree than the methods at University of Bergen, by providing space for the academically strongest students to prepare their own career, rather than contributing to the fellowship's development as the methods used in Bergen seem to do.

    Full Text Available För många studenter har det visat sig vara svårt att tillägna sig det språk som används i högre utbildning (Lea & Street, 1998; Hoel Løkensgard, 2010. Hindren för studenten kan bli så stora att de får svårt att genomföra sina studier. En viktig uppgift men också en stor utmaning för högskolans lärare är att stödja studenter i deras språkutveckling så att fler får möjlighet att fullfölja sin akademiska utbildning. Den här artikeln bygger på en kvalitativ undersökning av hur studenter vid ett tillfälle samtalar om en vetenskaplig artikel som ingår i deras utbildning. Vårt syfte är att diskutera vilka möjligheter innehållet i studenternas samtal ger för att utveckla deras förståelse av den vetenskapliga texten och dess kontext. I analysen framstår tre teman som avgörande för vad samtalen kom att handla om: studenternas syn på artikelns användbarhet, deras syn på artikelns tillförlitlighet samt deras attityder till den. Undersökningens resultat understryker lärarens viktiga roll i textsamtalen och pekar bland annat på att studenter behöver utveckla såväl diskursmedvetenhet som kunskap om de villkor som omger forskare och deras skrivande för att förstå och kritiskt kunna granska en vetenskaplig artikel.

    Full Text Available [english] Background: Besides theoretical knowledge, medical students have to acquire different skills during their medical education, which are essential especially for the physician’s routine practice. In July 2005 an interdisciplinary skills lab was set up at the Medical Faculty of the RWTH Aachen University. Financial and personnel resources for the structural and organizational development of the skills lab were obtained first from a faculty fund for innovative teaching concepts, and later from student fees. Methods: Elements of project management necessary for the skills lab were defined in advance: Development of a methodological concept, definition of content and selection of skills, provision of infrastructural necessities (rooms, media, staff, creation of a pilot course concept, definition of milestones, acquisition of powerful faculty partners for further support, implementation of courses within the ongoing curricula, and evaluation of individual courses and the entire concept. Results: The project management steps defined in advance were retrospectively proven necessary and important for the establishment of a minimum infrastructure in terms of spatial and human resources and for the implementation of the methodological concept. During the 2008 summer semester, a total of 709 students in 133 faculty courses and about 900 students in curricular courses used the skills lab. Conclusion: Three years on, the interdisciplinary skills lab offers a wide range of courses in which students can learn, train, and optimize their practical skills. The experiences gained in designing and organizing the program are essential for the further structural and methodological/didactic development of the skills lab.[german] Hintergrund: Neben theoretischem Wissen müssen Medizinstudierende Fertigkeiten unterschiedlichster Art erwerben, die nicht nur für die praktischen Ausbildungsteile im Studium, sondern in erster Linie für das tägliche

    Due to prevailing future challenges in vocational rehabilitation, development process RehaFutur (BMAS) was initiated. In this context, recommendations were made to secure a future-oriented, innovative vocational rehabilitation in Germany. Deutsche Rentenversicherung (DRV) Westfalen transferred these recommendations into a new and applicable counseling concept RehaFutuReal(®). Rehabilitation managers (RM) are central protagonists in counseling process. Therefore, RehaFuturReal(®) focused on optimization of counseling performance. To achieve this aim, rehabilitation managers were taught to work with a case management (CM) based approach. RWTH Aachen supported RehaFuturReal(®) from an academic point of view and conducted a formative and summative evaluation. Primary aim of RWTH Aachen was to support DRV Westfalen during implementation of RehaFuturReal(®) into their organizational structure. Additionally, RWTH Aachen controlled whether transfer of RehaFutuReal(®) in counseling process was successful. From 04-01-13 until 12-31-14, RehaFuturReal(®) was tested by DRV Westfalen in the intervention district Dortmund with 10 RM. There were 3 selection criteria for the overall sample of N=320 insurants: participants were required to have an active employment status, suffered from integration issues and were in need of support to achieve vocational integration. Evaluation of RehaFuturReal(®) was realized summative (pre-post-comparison) and formative (process-orientated). Evaluative judgment regarding implementation in organizational structure and counseling process was performed by using three-stage-concept of Donabedian (quality of structure, process and results). Thereby, feedback of RM, insurants and employers was taken into account. Analysis of evaluation results revealed a positive overall impression. Implementation into organizational structure was successful on all 3 quality stages: concept of project and CM-training were an adequate basis and appropriately put

    This special issue of Journal of Geophysics and Engineering is dedicated to a collection of papers which resulted from an international workshop held in Aachen, Germany, on 4-7 October 2004, called 'New and Classical Applications of Heat Flow Studies'. This was the third in a series of topical geothermal workshops arranged by the Geothermal Working Group of the German Geophysical Society (DGG) and was organized by the Institute of Applied Geophysics at RWTH Aachen University under the auspices of the International Heat Flow Commission of the International Association of Seismology and Physics (IASPEI). The meeting was attended by some 60 scientists from 14 countries and three continents. Financial assistance, granted by DGG and IASPEI, allowed us to provide partial support for a total of eight students, young scientists and eminent researchers from eastern Europe and overseas. The convenors of the meeting were Christoph Clauser (Aachen), Thomas Kohl (Zürich) and Makoto Taniguchi (Kyoto). The main local organizers were Volker Rath (scientific programme) and Ute Kreutz (accommodation and financial affairs). The topics addressed in more than 50 oral and poster presentations indicated that today intriguing new applications of heat flow studies have emerged, complementing the classical topics of heat flow mapping and the tectonic implications of heat flow. In classical applications, for instance, thermal signatures of water flow or downward diffusion of variations in the Earth's mean temperature are considered as noise which needs to be corrected prior to further use of the data. In contrast, in several new applications it is exactly the information contained in these signatures which has been extracted and interpreted. For instance, over the past two decades, work on the most prominent of these new applications has been devoted to inverting the variation of the Earth's past mean ground surface temperature (GST). As of today, GST provided by the geothermal method has

    The Saturnian moon Enceladus shows incidence of liquid water underneath a thick ice sheet cover and is thought to be a potential candidate for extraterrestrial life. However, direct exploration of these subglacial aquatic ecosystems is very challenging. Within the scope of the joint research project 'Enceladus Explorer' (EnEx) (consisting of FH Aachen, RWTH Aachen, Bergische Universität Wuppertal, Universität Bremen, TU Braunschweig und Bundeswehr Universität München), initiated by the German Space Agency, a maneuverable close-contact melting probe has been developed. The force-regulated and heater-controlled probe is able to melt against gravity or even on a curved trajectory. Hence, it offers additional degrees of freedom in its melting motion, e.g. for target oriented melting or obstacle avoidance strategies. General feasibility of the concept has been demonstrated in various field tests. However, in order to optimize its design and to adopt it to extraterrestrial missions a simulation model is needed, capable of determining melting velocity and efficiency at given environmental conditions and system configurations. Within this contribution, the physical situation is abstracted into a quasi-stationary mathematical model description, and a numerical solution strategy is developed to compute melting velocity and temperature distribution within the probe and the surrounding ice. We present an inverse solution approach, in which a background velocity field of the ice mimics the melting velocity. The fundamental balance laws are solved with the corresponding melting rate. Following Newton's laws, the resulting force acting on the probe has to balance the contact force exerted by the probe and can hence be used for convergence. We present both, analytical results to a simplified head geometry, as well as results from a simulation model implemented into the open source software Elmer for arbitrary head geometries. The latter can deal with the full 3d situation

    When developing geothermal resources, the risk of failure is still high when compared to hydrocarbon exploration. The MeProRisk projects aims at the improvement of strategies in all phases of the reservoir life cycle. It is a joint enterprise of five university institutes at RWTH Aachen University, Free University Berlin, and Kiel University. Two partners, namely Geophysica Beratunggesellschaft mbH, (Aachen), and RWE Dea AG (Hamburg) present the industrial side. It is funded by the German Ministry of Education and Science (BMBF). The key idea followed in this project is that the development of the understanding of a given reservoir is an iterative process. Starting from geological base knowledge and geophysical exploration one or more conceptual models will emerge, which will be incorporated in first numerical models. The use of inverse techniques in a broad sense will not only lead to an optimal model, but will produce uncertainty and resolution estimates for this model. This information may be used for further setup of optimal experiments, including the choice of exploration well locations. In later stages of reservoir development, the numerical models will be continuously updated based on the most recent models. Once wells have been drilled, the character of experiments shifts from static methods to dynamic interaction with the reservoir, e.g. by injection experiments and their monitoring. The use of all the methods with one simulation tool poses large challenges. Inverse problems require orders of magnitude larger computer resources, and the development of appropriate theoretical and numerical methods for this is on of the primary aims of this project. Due to the less obvious signatures of geothermally relevant targets, it is also necessary to improve the experimental base for model setup and update by developing new and better methods for some of the key problems in the case of geothermal targets. Among these are the development of methods to estimate

    To evaluate the psychometric properties of the Italian version of Functional Outcome Questionnaire - Aphasia. Two hundred and five persons with stroke-related aphasia and right hemiparesis who received ongoing assistance from a family caregiver were assessed using the Functional Outcome Questionnaire - Aphasia, Aachener Aphasie Test, Token Test, Raven's Coloured Progressive Matrices, Functional Independence Measure (FIM), Functional Assessment Measure (FAM), and Quality of Life Questionnaire for Aphasics (QLQA). The Functional Outcome Questionnaire - Aphasia was translated into the Italian language using a translation and back-translation method. Reliability and construct validity of the Functional Outcome Questionnaire - Aphasia were evaluated. The Italian version of the Functional Outcome Questionnaire - Aphasia showed good internal consistency and test-retest reliability for the overall scale (α = 0.98; ICC = 0.95) and subscales (α = 0.89 for the communicating basic needs (CBN), α = 0.92 for the making routine requests (MRR), α = 0.96 for the communicating new information (CNI), α = 0.93 for the attention/other communication skills (AO); ICC = 0.95 for CBN, ICC = 0.96 for MRR, ICC = 0.97 for CNI and ICC = 0.92 for AO). Significant correlations were found between the Functional Outcome Questionnaire - Aphasia and Token Test, QLQA, Aachener Aphasie Test scores, and FAM linguistic scores, indicating good convergent validity. Low correlations were found between Functional Outcome Questionnaire - Aphasia and Raven's Coloured Progressive Matrices and FIM motor scores, showing good discriminant validity. The overall findings of this study supported the reliability and construct validity of the Italian version of the Functional Outcome Questionnaire - Aphasia. This measure holds considerable promise in assessing the functional outcomes of aphasia rehabilitation in Italian-speaking persons with aphasia. Implications for

    Introduction: An increasing number of surgical procedures are performed in a microsurgical and minimally-invasive fashion. However, the performance of surgery, its possibilities and limitations become difficult to teach. Stereoscopic video has evolved from a complex production process and expensive hardware towards rapid editing of video streams with standard and HDTV resolution which can be displayed on portable equipment. This study evaluates the usefulness of stereoscopic video in teaching undergraduate medical students. Material and methods: From an earlier study we chose two clips each of three different microsurgical operations (tympanoplasty type III of the ear, endonasal operation of the paranasal sinuses and laser chordectomy for carcinoma of the larynx). This material was added by 23 clips of a cochlear implantation, which was specifically edited for a portable computer with an autostereoscopic display (PC-RD1-3D, SHARP Corp., Japan). The recording and synchronization of left and right image was performed at the University Hospital Aachen. The footage was edited stereoscopically at the Waseda University by means of our original software for non-linear editing of stereoscopic 3-D movies. Then the material was converted into the streaming 3-D video format. The purpose of the conversion was to present the video clips by a file type that does not depend on a television signal such as PAL or NTSC. 25 4th year medical students who participated in the general ENT course at Aachen University Hospital were asked to estimate depth clues within the six video clips plus cochlear implantation clips. Another 25 4th year students who were shown the material monoscopically on a conventional laptop served as control. Results: All participants noted that the additional depth information helped with understanding the relation of anatomical structures, even though none had hands-on experience with Ear, Nose and Throat operations before or during the course.

    Since due to the nuclear reactor accident in Chernobyl r[ionuclides arrived in the vicinity of Aachen, the enhancement of the local dose rate, the deposition of the different r[ionuclides on ground and vegetation and the transport of the r[ionuclides into the environment were measured. Partly the measurements were continued until today. Very informative time sequences of the specific activity in grass, food, cow's milk, beef, in the different plants, trees, ploughed soil and undisturbed soil, mushrooms, game, in humans etc. resulted. During different private and official journeys in the old Laender of the Federal Republic of Germany surface covering measurements of the 134 Cs and 137 Cs activity deposited on grass land at different places were carried out. These data were implemented into a map on ground contamination in 1986 in Germany, published in 1991 by the Institute for Water, Soil and Air Hygiene of the Federal Public Health Department in Berlin. Transfer factors soil-grass were measured in the whole Federal Republic of Germany analyzing grass samples which were partly taken at the same time. A large amount of r[ioecological parameters could be derived from the different time sequences. These are in particular: The deposition velocity for iodine and particle bound r[ioanuclides on grass and in forests, the rainout coefficient in dependence of the precipitation intensity, the retention factors on grass, the biological half-life time on grass, the transfer factor soil-grass in dependence of time, the transfer factor food-milk during the pasture period and during stable stay, the transfer factor food-beef, the transfer factors in eatable mushrooms, the translocation factor of cesium in cereals etc. A multi-compartment model was developed to calculate the specific Cs activity in cow's milk and beef. The specific activity in milk can be calculated sufficiently exact using a simple single compartment model. The correlation of the specific Cs activity in spruce

    The CMS computing model anticipates various hierarchically linked tier centres to counter the challenges provided by the enormous amounts of data which will be collected by the CMS detector at the Large Hadron Collider, LHC, at CERN. During the past years, various computing exercises were performed to test the readiness of the computing infrastructure, the Grid middleware and the experiment's software for the startup of the LHC which took place in September 2008. In Germany, several tier sites are set up to allow for an efficient and reliable way to simulate possible physics processes as well as to reprocess, analyse and interpret the numerous stored collision events of the experiment. It will be shown that the German computing sites played an important role during the experiment's preparation phase and during data-taking of CMS and, therefore, scientific groups in Germany will be ready to compete for discoveries in this new era of particle physics. This presentation focuses on the German Tier-1 centre GridKa, located at Forschungszentrum Karlsruhe, the German CMS Tier-2 federation DESY/RWTH with installations at the University of Aachen and the research centre DESY. In addition, various local computing resources in Aachen, Hamburg and Karlsruhe are briefly introduced as well. It will be shown that an excellent cooperation between the different German institutions and physicists led to well established computing sites which cover all parts of the CMS computing model. Therefore, the following topics are discussed and the achieved goals and the gained knowledge are depicted: data management and distribution among the different tier sites, Grid-based Monte Carlo production at the Tier-2 as well as Grid-based and locally submitted inhomogeneous user analyses at the Tier-3s. Another important task is to ensure a proper and reliable operation 24 hours a day, especially during the time of data-taking. For this purpose, the meta-monitoring tool 'HappyFace', which was

    With the first multicenter MCS study in Germany a research network could be established: Six environmental medicine out-patient clinics took part in the project, five of which were linked to university clinics (Aachen, Berlin, Freiburg, Giessen, Munich) and one located at a specialised hospital in Bredstedt. The department of environmental medicine at the Robert Koch-Institut (RKI) in Berlin served as the study-centre. The main focus of the study consisted of a precise description and detailed analysis of the 'Multiple Chemical Sensitivity' (MCS). The causes, triggers and risk factors of MCS were to be studied. The project is based primarily on a cross-sectional design. The division of the outpatients into MCS- and non-MCS-groups also corresponds to a case-control situation with outpatient clinic based cases and controls. The specially designed documentation instruments were developed and tested in 1999. 234 (80%) of the approximately 300 patients examined at the six centres in the year 2000 with completed examination instruments could be included in the study. First results will be presented. With regard to the medical assessment of MCS considerable differences between the centres were found. In the psychometric instruments self-reported MCS-patients scored predominantly in between healthy individuals and psychiatry/psychosomatic patients. (orig.)

Currently, there is limited information on the steam sterilization influence on the accuracy of MTDs. The purpose of this study was to assess the effect of steam sterilization on the accuracy (±10% of the target torque of spring-style mechanical torque devices for dental implants.Materials and methods: Fifteen new S-S MTDs and their appropriate drivers from three different manufacturers (Nobel Biocare, Straumann [ITI], and Biomet 3i [3i] were selected. Peak torque of devices (5 in each subgroup was measured before and after autoclaving using a Tohnichi torque gauge. Descriptive statistical analysis was used and a repeated-measures ANOVA with type of device as a between-subject comparison was performed to assess the difference in accuracy among the three groups of spring-style mechanical torque devices after sterilization. A Bonferroni post hoc test was used to assess pairwise comparisons.Results: Before steam sterilization, all the tested devices stayed within 10% of their target values. After 100 sterilization cycles, results didn't show any significant difference between raw and absolute error values in the Nobel Biocare and ITI devices; however the results demonstrated an increase of error values in the 3i group (P < 0.05.

    Gales, B.P.A.

    2002-01-01

    This book considers the development of coal mining in the Dutch province of Limburg during the eighteenth and nineteenth centuries. It is focused on the technical development and its economic background. Within the Dutch borders, as defined at the Congress of Vienna and the Dutch-Prussian negotiations of 1815 and 1816, the mining industry was small. In fact, it only consisted of two mines. (Earlier, more companies of miners had been working in the area since the Middle Ages). The two mines, however, had a certain symbolic importance for contemporaries. Most telling was the stubborn refusal to cede coal-ground to Prussia, ending in a remarkable compromise. The new national frontier was different above and underground. Underground the old borders were maintained. Thus it came about that in matters of mining, the Dutch were locally sovereign under a foreign surface. This fact itself shows that the political divisions of the nineteenth and twentieth centuries were rather artificial constructions. Dutch coal-strata were a continuation of the seams of the Worm-basin or the Aachen coal field. The Dutch collieries were just the most north-western ones of a whole series, the Worm-mines, until new pits were constructed around the turn of the nineteenth and into the twentieth centuries and modem mining in the Dutch-Limburg field took off. This is also the more general perspective taken in this book. Developments on the Dutch side of the border are contrasted with those on the German side. Furthermore, the evolution of the mines between Aachen in Germany and the Dutch town Kerkrade are considered in the light of what happened in the neighbourhood of Liege (Belgium) and the mining districts further south in Belgium, the north of France and both the Ruhr and Saar districts in Germany. In short, the Austrasian field, the concept framed by Wrigley in 1962, is the locus of reference. The symbolic importance of Dutch coal mining stimulated a series of experiments in bringing the

    2001-07-01

    After numerous experiences in the domain of big and medium-size cogeneration, some European municipalities, in particular in Germany, are developing small-size cogeneration units. The aim of this study is, first, to examine the policies and experiences of municipalities and municipal energy companies in terms of technology utilization and the way they have integrated these new technologies in existing installations. Secondly, its aim is to provide some information about the technical and organizational aspects, in particular about the difficulties encountered and the results obtained. In the domain of small cogeneration, various technologies enter in competition: combustion engines, combustion turbines, Stirling engine and fuel cells, which have reached different stages of technical and commercial development. All these technologies are described in case-forms. The ten examples described in these forms (Aachen (DE), Armagh (UK), Arnhem (NL), Basel (CH), Bielefeld (DE), Berlin (DE), Chelles (FR), Frankfurt (DE), Land Hessen (DE), and Ludwigshafen (DE)), indicate that today, only the facilities equipped with gas engines are economically competitive with respect to other means of electricity and heat generation.

During a 2-week treatment period, half of the participants received 10 sessions of 20-minute inhibitory 1-Hz rTMS over the right inferior frontal gyrus (Brodmann area 45), and the other half received sham stimulation. Directly thereafter, all the participants underwent 45 minutes of speech and language therapy. Aachen Aphasia Test, Amsterdam-Nijmegen Everyday Language Test (ANELT), a naming screening, and subscales of the FIM, all assessed the day before and the day after treatment period. The participants who received real rTMS significantly improved with respect to all 10 measures of basic linguistic skills and functional communication, whereas sham-treated participants significantly improved in only 6 of 10 measures (paired t tests, Pcommunication (ANELT) (repeated-measures analysis of variance, P≤.05). For the first time, this study has demonstrated that basic linguistic skills as well as functional communication are bolstered by combining rTMS and behavioral language therapy in patients with subacute aphasia.

    The authors compared the effectiveness of 2 intensive therapy methods: Constraint-Induced Aphasia Therapy (CIAT; Pulvermüller et al., 2001) and semantic therapy (BOX; Visch-Brink & Bajema, 2001). Nine patients with chronic fluent aphasia participated in a therapy program to establish behavioral treatment outcomes. Participants were randomly assigned to one of two groups (CIAT or BOX). Intensive therapy significantly improved verbal communication. However, BOX treatment showed a more pronounced improvement on two communication-namely, a standardized assessment for verbal communication, the Amsterdam Nijmegen Everyday Language Test (Blomert, Koster, & Kean, 1995), and a subjective rating scale, the Communicative Effectiveness Index (Lomas et al., 1989). All participants significantly improved on one (or more) subtests of the Aachen Aphasia Test (Graetz, de Bleser, & Willmes, 1992), an impairment-focused assessment. There was a treatment-specific effect. BOX treatment had a significant effect on language comprehension and semantics, whereas CIAT treatment affected language production and phonology. The findings indicate that in patients with fluent aphasia, (a) intensive treatment has a significant effect on language and verbal communication, (b) intensive therapy results in selective treatment effects, and (c) an intensive semantic treatment shows a more striking mean improvement on verbal communication in comparison with communication-based CIAT treatment.

    Background. Patients with brain lesions and resultant chronic aphasia frequently suffer from depression. However, no effective interventions are available to target neuropsychiatric symptoms in patients with aphasia who have severe language and communication deficits. Objective. The present study aimed to investigate the efficacy of 2 different methods of speech and language therapy in reducing symptoms of depression in aphasia on the Beck Depression Inventory (BDI) using secondary analysis (BILAT-1 trial). Methods. In a crossover randomized controlled trial, 18 participants with chronic nonfluent aphasia following left-hemispheric brain lesions were assigned to 2 consecutive treatments: (1) intensive language-action therapy (ILAT), emphasizing communicative language use in social interaction, and (2) intensive naming therapy (INT), an utterance-centered standard method. Patients were randomly assigned to 2 groups, receiving both treatments in counterbalanced order. Both interventions were applied for 3.5 hours daily over a period of 6 consecutive working days. Outcome measures included depression scores on the BDI and a clinical language test (Aachen Aphasia Test). Results. Patients showed a significant decrease in symptoms of depression after ILAT but not after INT, which paralleled changes on clinical language tests. Treatment-induced decreases in depression scores persisted when controlling for individual changes in language performance. Conclusions. Intensive training of behaviorally relevant verbal communication in social interaction might help reduce symptoms of depression in patients with chronic nonfluent aphasia. PMID:29192534

    To withstand the higher particle rates of LHC Runs 2 and 3, with expected luminosities of up to $2\\times 10^{34}\\,\\mathrm{cm^{-2}s^{-1}}$, the current CMS pixel detector at the LHC will be replaced as part of the CMS Phase I Upgrade during the extended winter shutdown in 2016/17. The new pixel detector features a new geometry with one additional detector layer in the barrel region~(BPIX) and one pair of additional disks in the forward region~(FPIX), new digital readout chips as well as a new CO$_{2}$-based cooling system for both the barrel and forward region. The BPIX detector module production is summarized, with special focus on the different stages of quality assurance. The quality tests as well as the calibrations which all produced modules undergo in a temperature and humidity controlled environment are described. Exemplarily, the KIT/Aachen production line and its subprocesses are presented together with its quality and yields.

    In Germany's energy markets of today, pumped-storage power plants offer excellent business opportunities due to their outstanding flexibility. However, the energy-economic simulation of pumped-storage plants, which is necessary to base the investment decision on a sound business case, is a highly complex matter since the plant's capacity must be optimized in a given plant portfolio and between two relevant markets: the scheduled wholesale and the reserve market. This mathematical optimization problem becomes even more complex when the question is raised as to which type of machine should be used for a pumped-storage new build option. For the first time, it has been proven possible to simulate the optimum dispatch of different pumped-storage machine concepts within two relevant markets - the scheduled wholesale and the reserve market - thereby greatly supporting the investment decision process. The methodology and findings of a cooperation study between E.ON and RWTH Aachen University in respect of the German pumped-storage extension project 'Waldeck 2+' are described, showing the latest development in dispatch simulation for generation portfolios.

    In modern applications, high strength steels are often utilised to increase the load bearing capacity of components. For safe design it is also necessary that these steels have an adequate fracture toughness. The mechanical properties of high strength structural steels are a result of the production process. In consequence, they are strongly related to the microstructure. Therefore, the aim of the research work in the Microtough project is to develop and apply a new method of quantitative correlation between microstructural parameters and characteristic fracture toughness values. This correlation will on the one hand help for the design of new structural steels with high toughness. On the other hand, it shall allow to characterise the fracture toughness of steel without performing expensive fracture mechanics tests. The research work is carried out in the full temperature range from lower to upper shelf. As both RWTH Aachen University and MPA Uni Stuttgart concentrate on ductile fracture behaviour in their research work, the focus of the presentation lies in the upper shelf. (orig.)

    To obtain further insights into the rehabilitation outlook in different baseline conditions, a comparison was made of data and treatment outcomes in 92 patients having aphasias of different etiology and disease duration. Rating as "improved" was contingent on significant changes in at least 2 subtests of the AAT (Aachener Aphasietest), which is a fairly stringent requirement. This criterion was met by some 35% of the patients overall, independent of their age; the percentage increased to 45% in case of treatment onset during the first year, while in later onset, significant improvement was achieved in 15% only. Aphasic syndromes secondary to hemorrhage, trauma, tumors, or infections, usually are less severe than the predominant classical syndromes, i.e. Global, Broca and Wernicke aphasia, caused by ischemic stroke. CT lesion size did not yield any definite information. Minor improvements below the required significance levels, and, above all, gains in communication performance, i.e. further consolidation, could be achieved by appropriate management even after the crucial initial year, which, however, does not imply any fundamental changes in the rehabilitation prognosis as such.

    Full Text Available Aphasia is a complex disorder, frequent after stroke (~38%, with a detailed pathophysiological characterization. Proper approaches are mandatory to devise an efficient rehabilitative strategy, in order to address the everyday life and professional disability. Several rehabilitative procedures are based on psycholinguistic, cognitive, psychosocial or pragmatic approaches, among these with neurobehavioral ratio, the Melodic Intonation Therapy (MIT .Van Eeckhout’s adaptation to the French language (Melodic-Rhythmic Therapy: MRT has implemented the training strategy by adding a rhythmic structure reproducing the French prosody.Purposes of this study were to adapt the MRT rehabilitation procedures to the Italian language and to verify its efficacy in a group of 6 chronic patients (5 males with severe non-fluent aphasia and without specific aphasic treatments at least from 9 months. The patients were treated 4 days a week for 16 weeks, with sessions of 30-40 min. They were assessed 6 months after the end of the treatment (follow-up. The patients showed a significant improvement at the Aachener Aphasie Test in different fields of spontaneous speech, with superimposable results at the follow-up. Albeit preliminary, these findings support the use of MRT in the rehabilitation after stroke. Specifically, MRT seems to benefit from its stronger structure than the available stimulation-facilitation procedures and allows a better quantification of the rehabilitation efficacy.

    Fibre reinforced composites are differentiated by the used matrix material (thermoplastic versus duroplastic matrix) and the level of impregnation. Thermoplastic matrix systems get more important due to their suitability for mass production, their good shapeability and their high impact resistance. A challenge in the processing of these materials is the reduction of the melt flow paths of the thermoplastic matrix. The viscosity of molten thermoplastic material is distinctly higher than the viscosity of duroplastic material. An approach to reduce the flow paths of the thermoplastic melt is given by a commingling process. Composites made from commingling hybrid yarns consist of thermoplastic and reinforcing fibres. Fabrics made from these hybrid yarns are heated and consolidated by the use of heat pressing to form so called organic sheets. An innovative heating system is given by microwaves. The advantage of microwave heating is the volumetric heating of the material, where the energy of the electromagnetic radiation is converted into thermal energy inside the material. In this research project microwave active hybrid yarns are produced and examined at the Institute for Textile Technology of RWTH Aachen University (ITA). The industrial research partner Fricke und Mallah Microwave Technology GmbH, Peine, Germany develops an innovative pressing systems based on a microwave heating system. By implementing the designed microwave heating technology into an existing heat pressing process, FRTCs are being manufactured from glass and nanomodified polypropylene fibre woven fabrics. In this paper the composites are investigated for their mechanical and optical properties.

    Combustion of pulverized coal in oxy-combustion technology is one of the effective ways to reduce the emission of greenhouse gases into the atmosphere. The process of transition from conventional combustion in air to the oxy-combustion technology, however, requires a thorough investigations of the phenomena occurring during the combustion process, that can be greatly supported by numerical modeling. The paper presents the results of numerical simulations of pulverized coal combustion process in swirl burner using RANS (Reynolds-averaged Navier–Stokes equations) and LES (large Eddy simulation) methods for turbulent flow. Numerical simulations have been performed for the oxyfuel test facility located at the Institute of Heat and Mass Transfer at RWTH Aachen University. Detailed analysis of the flow field inside the combustion chamber for cold flow and for the flow with combustion using different numerical methods for turbulent flows have been done. Comparison of the air and oxy-coal combustion process for pulverized coal shows significant differences in temperature, especially close to the burner exit. Additionally the influence of the combustion model on the results has been shown for oxy-combustion test case. - Highlights: • Oxy-coal combustion has been modeled for test facility operating at low oxygen ratio. • Coal combustion process has been modeled with simplified combustion models. • Comparison of oxy and air combustion process of pulverized coal has been done. • RANS (Reynolds-averaged Navier–Stokes equations) and LES (large Eddy simulation) results for pulverized coal combustion process have been compared

  9. A New Low NOx Combustion Concept for Fan-assisted gas Burners

    Jaeger, F. Kleine; Koehne, H.

    1999-01-01

    The Department of Heat and Mass Transfer at Aachen Technical University has developed a combustion concept which makes low-emission combustion inside a burn-up chamber possible. In addition to the very low NOx emissions (ENOX < 10 mg/kWh) the fan-assisted gas burner is characterised by the comparatively low noise emissions which are obtained from the stabilisation of the flame within the burn-up chamber and the low flow rates in the flame. The main aim of the fan-assisted gas burner development work is to influence the thermal nitrogen oxide formation in order to obtain minimum emissions combined with low combustion noise. High fan pressures and the resulting increase in turbulence energy in marketable fan-assisted burner concepts often cause a high excitation of thermo-acoustic vibrations which are heard as interfering combustion noises and are often emitted via the chimney into the living space. Low noise emission must therefore be taken into consideration when approaches to reduce nitrogen oxide emissions are developed. One approach which achieves this aim and is in use is combustion on porous surfaces. This reduces the flow rates and therefore the kinetic turbulence energy. One problem with these concepts is, however, the thermal loading of the material which is exposed to a high thermal alternating stress which sometimes makes it brittle. An uneven flow rate distribution can also lead to increased emission of harmful substances. (author)

    Full Text Available This paper describes a project carried out by the German National Library, the University and State Library Sachsen-Anhalt in Halle and Semantics GmbH Aachen to establish routines of persistent identification for individual pages of web publications in order to enable and facilitate reliable and long-term valid citation practices for the academic community. The project originated in a pilot project to digitise approximately 10,000 German imprints from the seventeenth century comprising altogether about 600,000 pages, which had to be completed within two years. The material of the ‘Ponickau Collection’ had been catalogued in the German national bibliography of seventeenth-century imprints (VD 17, which was enriched and turned into a virtual library by adding the digitised texts. This article investigates the means of presentation and indexing of digitised imprints in order to ensure their usability. It also sketches the workflow among the various partners involved in the process. The article highlights the application of Visual Library, which contains various tools for automated creation of metadata, the implementation of persistent identifiers (URN and the automated enrichment of catalogue entries by the regional cataloguing cooperative Gemeinsamer Bibliotheksverbund (GBV. Special emphasis is given to questions of quality management; the quality is guaranteed by a combination of automated tools and intellectual control at various stages of the digitisation process.

    The aim of this research is to evaluate the effects of active music therapy (MT) based on free-improvisation (relational approach) in addition to speech language therapy (SLT) compared with SLT alone (communicative-pragmatic approach: Promoting Aphasic's Communicative Effectiveness) in stroke patients with chronic aphasia. The experimental group (n = 10) was randomized to 30 MT individual sessions over 15 weeks in addition to 30 SLT individual sessions while the control group (n = 10) was randomized to only 30 SLT sessions during the same period. Psychological and speech language assessment were made before (T0) and after (T1) the treatments. The study shows a significant improvement in spontaneous speech in the experimental group (Aachener Aphasie subtest: p = 0.020; Cohen's d = 0.35); the 50% of the experimental group showed also an improvement in vitality scores of Short Form Health Survey (chi-square test = 4.114; p = 0.043). The current trial highlights the possibility that the combined use of MT and SLT can lead to a better result in the rehabilitation of patients with aphasia than SLT alone.

    Clinical language performance and neurophysiological correlates of language processing were measured before and after intensive language therapy in patients with chronic (time post stroke >1 year) post stroke aphasia (PSA). As event-related potential (ERP) measure, the mismatch negativity (MMN) was recorded in a distracted oddball paradigm to short spoken sentences. Critical ‘deviant’ sentence stimuli where either well-formed and meaningful, or syntactically, or lexico-semantically incorrect. After 4 weeks of speech-language therapy (SLT) delivered with high intensity (10.5 h per week), clinical language assessment with the Aachen Aphasia Test battery demonstrated significant linguistic improvements, which were accompanied by enhanced MMN responses. More specifically, MMN amplitudes to grammatically correct and meaningful mini-constructions and to ‘jabberwocky’ sentences containing a pseudoword significantly increased after therapy. However, no therapy-related changes in MMN responses to syntactically incorrect strings including agreement violations were observed. While MMN increases to well-formed meaningful strings can be explained both at the word and construction levels, the neuroplastic change seen for ‘jabberwocky’ sentences suggests an explanation in terms of constructions. The results confirm previous reports that intensive SLT leads to improvements of linguistic skills in chronic aphasia patients and now demonstrate that this clinical improvement is associated with enhanced automatic brain indexes of construction processing, although no comparable change is present for ungrammatical strings. Furthermore, the data confirm that the language-induced MMN is a useful tool to map functional language recovery in PSA. PMID:28111545

    The first measurement of the jet mass [Formula: see text] of top quark jets produced in [Formula: see text] events from pp collisions at [Formula: see text] [Formula: see text] is reported for the jet with the largest transverse momentum [Formula: see text] in highly boosted hadronic top quark decays. The data sample, collected with the CMS detector, corresponds to an integrated luminosity of 19.7[Formula: see text]. The measurement is performed in the lepton+jets channel in which the products of the semileptonic decay [Formula: see text] with [Formula: see text] where [Formula: see text] is an electron or muon, are used to select [Formula: see text] events with large Lorentz boosts. The products of the fully hadronic decay [Formula: see text] with [Formula: see text] are reconstructed using a single Cambridge-Aachen jet with distance parameter [Formula: see text], and [Formula: see text] [Formula: see text]. The [Formula: see text] cross section as a function of [Formula: see text] is unfolded at the particle level and is used to test the modelling of highly boosted top quark production. The peak position of the [Formula: see text] distribution is sensitive to the top quark mass [Formula: see text], and the data are used to extract a value of [Formula: see text] to assess this sensitivity.

  14. A Survey of Utopia—Creating Filmic Travelogues in Architectural Design Studio Education †

    Full Text Available This paper investigates the potential of the creation of filmic travelogues in architectural design studio education. It looks at student works from a studio conducted at RWTH Aachen University in the summer term of 2017 and explores how the works construct meaning from and reflect on architectural reference in an active creative process. The assignment of the studio was to create a travelogue of a 4-day excursion to Belgium and the South of England in the form of a short film. Inspired by Patrick Keiller’s film Robinson in Space, the students were invited to explore the Situationist techniques of Drifting and Psychogeography, and to use them in their visual storytelling. The studio´s title A Survey of Utopia makes reference to the architectural and urbanistic projects that were visited: visionary residential projects from the 1960s to 1980s, built by well-known architects of this period, such as Lucien Kroll, Walter Segal and Leon Krier. The term utopia hints at the projects shared interest in radical change and bold new architectural approaches, even though each pursues its own distinct kind of utopia.

    Resulting from the continuous increase of freight transport and the limitation of the capacity for road-transport, there is a need of optimising road traffic flow and of improving the utilisation of the given infrastructure. The objective is making the whole traffic system safer, more efficient and environmentally friendly. A potential concept is the realisation of truck platoons on highways by using advanced driver assistant systems (ADAS). The electronic coupling of the trucks in short distance minimises the work-load of the truck drivers and results in a safety benefit. Furthermore the short distances lead to a positive effect on road capacity and a reduction of the fuel consumption of the following vehicles because of lee-driving. Within a project ''Preparing action for the realisation of advanced driver assistant system in freight transport'' a group of scientists of the Aachen University worked on requirements for the medium-term realisation of automatic truck platoons on highways.

    The aim of the LHC workshop at Aachen was to discuss the 'discovery potential' of a high-luminosity hadron collider (the Large Hadron Collider) and to define the requirements of the detectors. Of central interest was whether a Higgs particle with mass below 1 TeV could be seen using detectors potentially available within a few years from now. Other topics included supersymmetry, heavy quarks, excited gauge bosons, and exotica in proton-proton collisions, as well as physics to be observed in electron-proton and heavy-ion collisions. A large part of the workshop was devoted to the discussion of instrumental and detector concepts, including simulation, signal processing, data acquisition, tracking, calorimetry, lepton identification and radiation hardness. The workshop began with parallel sessions of working groups on physics and instrumentation and continued, in the second half, with plenary talks giving overviews of the LHC project and the SSC, RHIC, and HERA programmes, summaries of the working groups, presentations from industry, and conclusions. Vol.1 of these proceedings contains the papers presented at the plenary sessions, Vol.2 the individual contributions to the physics sessions, and Vol.3 those to the instrumentation sessions. (orig.)

    2013-01-01

    Arnold Sommerfeld (1868-1951) belongs with Max Planck (1858-1947), Albert Einstein (1879-1955) and Niels Bohr (1885-1962) among the founders of modern theoretical physics, a science that developed into a budding discipline during his lifetime. Sommerfeld witnessed many of the most dramatic scientific, cultural and political events of this era. His correspondence with his family offers a vivid testament to the challenges and joys of a life in science. This biography attempts to reconstruct Sommerfeld’s life and work not only from the perspective of his achievements in theoretical physics but also with the goal of portraying the career of a scientist within the social and political environment in which it evolved. It is based to a large extent on Sommerfeld’s voluminous correspondence, which sheds light both on his private and scientific life. Furthermore, it provides an authentic view on the circumstances that shaped Sommerfeld’s career in different places – Königsberg, Göttingen, Clausthal, Aachen, ...

    Preliminary reports suggest that central stimulation may enhance the effect of conventional physical therapies after stroke. This pilot study examines the safety and methodology of using transcranial direct stimulation (tDCS) with robot-assisted arm training (AT), to inform planning a larger randomised controlled trial. Ten patients, after an ischaemic stroke 4-8 weeks before study onset, no history of epilepsy, participated. Eight had a cortical lesion and 2 had subcortical lesions: all had severe arm paresis and, co-incidentally, 5 had severe aphasia. Over six weeks, they received thirty 20 min-sessions of AT. During the first 7 minutes, 1.5mA of tDCS was applied, with the anode over the lesioned hemisphere and the cathode above the contralateral orbit. Arm and language impairment were assessed with the Fugl-Meyer motor score (FM, full range 0-66) and the Aachener Aphasie Test. No major side effects occurred. Arm function of three patients (two with a subcortical lesion) improved significantly, with FM scores increasing from 6 to 28, 10 to 49 and 11 to 48. In the remaining seven patients, all with cortical lesions, arm function changed little, FM scores did not increase more than 5 points. Unexpectedly, aphasia improved in 4 patients. These procedures are safe, and easy to use in a clinical setting. In future studies, patients should be stratified by degree of arm weakness and lesion site, also the unexpected aphasia improvement warrants following-up.

    With the present experiment we sought to investigate brain plasticity underlying language recovery in a group of seventeen patients with non-fluent aphasia mainly caused by stroke. Patients were screened along three domains of measures: analysis of linguistic components by the Aachener Aphasie Test, combined mapping of their lesion from CT/MRI scans, and functional measure of the reorganized linguistic processes by means of mapping of slow evoked potentials. The spatial dimension and temporal dynamics of word processing were measured in three tasks, Phonological, Semantic and Orthographic. Compared with the matched control group, patients showed relative inhibition (decreased negativity) of left central regions in perisylvian areas, which were damaged in most subjects. In addition, reorganization of linguistic functions occurred within the left hemisphere both at frontal and posterior sites corresponding to spared brain regions. Correlations between linguistic lateralization in the three tasks and AAT subtests point to functional reorganization of phonological processes over left frontal sites and dysfunctional reorganization of semantic processing over left posterior regions.

    Twenty-six aphasic patients who had an ischaemic infarct in the territory of the left middle cerebral artery (MCA) were investigated. Cranial computed tomography (CT) showed various lesion sites: infarcts restricted to cortical structures in 12 patients, combined cortical and subcortical infarcts in 7 and isolated subcortical infarcts sparing the left cortex in another 7 cases. 18F-2-fluoro-2-deoxyglucose positron emission tomography revealed remote hypometabolism of the left convexity cortex and of the left basal ganglia, which was extended further than the morphological infarct zone in all cases. Types and degrees of aphasia were classified using the Aachener Aphasie Test (AAT): 10 patients had global aphasia, 2 Broca's, 5 Wernicke's, and 5 amnesic aphasia. Four patients suffered from minimal or residual aphasic symptoms. The AAT results were compared with the regional cerebral metabolic rates of glucose of the left hemisphere. Irrespective of the infarct location all five AAT subtests (Token test, repetition, written language, confrontation naming, auditory and reading comprehension) were closely correlated among each other and with left parieto-temporal metabolic rates, whereas left frontal and left basal ganglia metabolism showed no significant correlation. The close relation between left temporo-parietal functional activity and all five AAT subtests suggests that the different aspects of aphasia tested by AAT can be related to a common disorder of language processing in those areas.

    Space occupying supratentorial ischemic stroke has a high mortality. The benefit of decompressive surgery in these patients is still matter of debate. In a prospective study we performed craniectomy in 37 patients with acute middle cerebral artery infarction and progressive deterioration under conservative antiedematous therapy. Twenty-one patients treated conservatively during the same period served as control group. All survivors were reexamined between one to two years after surgical decompression. In addition, neuropsychological tests were performed, including an Aachener Aphasie Test (AAT) in those patients with infarction of speech-dominant hemisphere. Clinical evaluation was graded using the Barthel index (BI). Mortality rate in the operated group was 37%. Twenty-three patients survived acute stroke and were reexamined. Despite complete hemispheric infarction, no patient suffered from complete hemiplegia or was permanently wheel chair bound. In speech dominant hemispheric infarction (n = 8) only mild to moderate aphasia could be detected. Mean BI was 64. Mortality rate in the conservatively treated group was 76%. The clinical outcome following craniectomy for the treatment of severe ischemic hemispheric infarction is unexpectedly good. Therefore, decompressive surgery should be considered in cases of space-occupying hemispheric infarctions and conservatively uncontrollable intracranial pressure.

    2005-01-01

    The Compact Muon Solenoid (CMS) is one of four large-scale experiments that is going to be installed at the Large Hadron Collider (LHC) at the European Laboratory for Particle Physics (CERN). For CMS an inner tracking system entirely equipped with silicon microstrip detectors was chosen. With an active area of about 198 m2 it will be the largest tracking device of the world that was ever constructed using silicon sensors. The basic components in the construction of the tracking system are approximately 16,000 so-called modules, which are pre-assembled units consisting of the sensors, the readout electronics and a support structure. The module production is carried out by a cooperation of number of institutes and industrial companies. To ensure the operation of the modules within the harsh radiation environment extensive tests have to be performed on all components. An important contribution to the quality assurance of the modules is made by a test system of which all components were developed in Aachen. In ad...

    At the European Organization for Nuclear Research (CERN) ne ar Geneva the new proton-proton collider ring LHC and the experiments that will be operated a t this accelerator are currently being finalised. Among these experiments is the multi-purpose det ector CMS whose aim it is to discover and investigate new physical phenomena that might become ac cessible by virtue of the high center- of-mass energy and luminosity of the LHC. Two of the most inte nsively studied possibilities are the discovery of the Higgs Boson and of particles from the spectr um of supersymmetric extensions of the Standard Model. CMS is the first large experiment of high- energy particle physics whose inner tracking system is exclusively instrumented with silicon d etector modules. This tracker comprises 15 148 silicon strip modules enclosing the interaction poin t in 10–12 layers. The 1.

    This thesis deals with preparations for the experiment CMS (Compact Muon Solenoid) of the LHC (Large Hadron Collider) planned at CERN in Geneva (Switzerland). The construction of the muon system, especially of the drift chambers in the barrel detector constructed with participation of the Aachen group, is explained. In the first part of the thesis the results from a Monte-Carlo-study for a decay channel interesting for the search for the Higgs boson at CMS is presented. In this channel the Higgs finally decays into four muons. The second part describes the running production of the drift chambers as well as results of tests developed and implemented for purposes of quality control. The LHC will accelerate protons to a center of mass energy of 14 TeV, aspiring to a luminosity of L = 10^34 cm^-2s^-1, allowing for the production of a sufficient number of such processes as rare as the production of Higgs bosons, which were predicted, but not yet proven. The Higgs bosons, created mainly by gluon gluon fusion in pr...

    2008-01-01

    Full Text Available Besides lectures on basic theoretical topics, contemporary teaching and learning concepts for first semester students give more and more consideration to practically motivated courses. In this context, a new first-year introductory course in practical engineering has been established in the first semester curriculum of Electrical Engineering at RWTH Aachen University, Germany. Based on a threefold learning concept, programming skills in MATLAB are taught to 309 students within a full-time block course laboratory. The students are encouraged to transfer known mathematical basics to program algorithms and real-world applications performed by 100 LEGO Mindstorms robots. A new MATLAB toolbox and twofold project tasks have been developed for this purpose by a small team of supervisors. The students are supervised by over 60 tutors at 23 institutes, and are encouraged to create their own robotics applications. We describe how the laboratory motivates the students to act and think like engineers and to solve real-world issues with limited resources. The evaluation results show that the proposed practical course concept successfully boosts students’ motivation, advances their programming skills, and encourages the peer learning process.

    At the Emsland nuclear power station, a total of 58 autocatalytic hydrogen recombiners were backfitted in 1999 as an additional measure of risk reduction in connection with major hydrogen releases after events going beyond the design basis. Annual in-service inspections after 2002 revealed that some of the catalyst sheets developed startup delays and marked evolutions of smoke and smell. Recombiners not meeting the inspection criterion were completely regenerated as a measure of precaution. A preventive study was conducted jointly with institutes of the Juelich Research Center and the Aachen Technical University to analyze the composition of the deposits, which was then compared with the chemical characteristics of potential sources in the reactor containment. At the same time, the influence on effectiveness of the catalyst sheets was examined. On the basis of a random evaluation of the in-service inspection logs of the past few years, representative samples were taken whose startup behavior and operating characteristics were studied in a test rig alongside chemical analyses so as to allow a correlation to be established between the analytical findings and the catalytic activity of the samples. The findings made allowed internal sources of the catalyst deposits to be excluded. The impurities are introduced with the outside air. As a consequence, the air ducts in the vicinity of the respective recombiners were inspected and optimization steps were taken in connection with in-service inspections and regeneration procedures.

    The VISPA internet platform enables users to remotely run Python scripts and view resulting plots or inspect their output data. With a standard web browser as the only user requirement on the client-side, the system becomes suitable for blended learning approaches for university physics students. VISPA was used in two consecutive years each by approx. 100 third year physics students at the RWTH Aachen University for their homework assignments. For example, in one exercise students gained a deeper understanding of Einsteins mass-energy relation by analyzing experimental data of electron-positron pairs revealing J / Ψ and Z particles. Because the students were free to choose their working hours, only few users accessed the platform simultaneously. The positive feedback from students and the stability of the platform lead to further development of the concept. This year, students accessed the platform in parallel while they analyzed the data recorded by demonstrated experiments live in the lecture hall. The platform is based on experience in the development of professional analysis tools. It combines core technologies from previous projects: an object-oriented C++ library, a modular data-driven analysis flow, and visual analysis steering. We present the platform and discuss its benefits in the context of teaching based on surveys that are conducted each semester.

  15. Large hadron collider workshop. Proceedings. Vol. 1

    1990-01-01

    The aim of the LCH workshop at Aachen was to discuss the 'discovery potential' of a high-luminosity hadron collider (the Large Hadron Collider) and to define the requirements of the detectors. Of central interest was whether a Higgs particle with mass below 1 TeV could be seen using detectors potentially available within a few years from now. Other topics included supersymmetry, heavy quarks, excited gauge bosons, and exotica in proton-proton collisions, as well as physics to be observed in electron-proton and heavy-ion collisions. A large part of the workshop was devoted to the discussion of instrumental and detector concepts, including simulation, signal processing, data acquisition, tracking, calorimetry, lepton identification and radiation hardness. The workshop began with parallel sessions of working groups on physics and instrumentation and continued, in the second half, with plenary talks giving overviews of the LHC project and the SSC, RHIC, and HERA programmes, summaries of the working groups, presentations from industry, and conclusions. Vol. 1 of these proceedings contains the papers presented at the plenary sessions, Vol. 2 the individual contributions to the physics sessions, and Vol. 3 those to the instrumentation sessions.

    On 5 and 11 November, almost 90 pupils from the Fermi scientific high school in Livorno, Italy, took part in two Masterclass sessions organised by CMS.   CMS Masterclass participants.  The pupils took over a hall at CERN for an afternoon to test a new software tool called CIMA (CMS Instrument for Masterclass Analysis) for the first time. The software simplifies the process of recording results and reduces the number of steps required to enter data. During the exercise, each group of pupils had to analyse about a hundred events from the LHC. For each event, the budding physicists determined whether what they saw was a candidate W boson, Z boson or Higgs boson, identified the decay mode and entered key data. At the end of the analysis, they used the results to reconstruct a mass diagram. CIMA was developed by a team of scientists from the University of Aachen, Germany, the University of Notre-Dame, United States, and CERN. CMS has also added yet another educational tool to its already l...

    Sowa, Michael Christian

    The Phys. Inst. III A of RWTH Aachen University is involved in the development, production and tests of the Drift Tube (DT) muon chambers for the barrel muon system of the CMS detector at the LHC at CERN (Geneva). The thesis describes some test procedures which were developed and performed for the chamber local Data Acquisition (DAQ) system, as well as for parts of the Detector Control System (DCS). The test results were analyzed and discussed. Two main kinds of DAQ tests were done. On the one hand, to compare two different DAQ systems, the chamber signals were split and read out by both systems. This method allowed to validate them by demonstrating, that there were no relevant differences in the measured drift times, generated by the same muon event in the same chamber cells. On the other hand, after the systems were validated, the quality of the data was checked. For this purpose extensive noise studies were performed. The noise dependence on various parameters (threshold, HV) was investigated quantitativel...

    Future neutrino telescopes with the aim to explore the extreme high energy region (above 10{sup 18} eV) require 2-3 orders of magnitude larger effective volumes compared to current optical detectors (IceCube 1 km{sup 3}). One possible approach is the acoustic detection of the thermo-acoustic pressure wave generated by hadronic cascades in neutrino interactions. A major goal of the Aachen Acoustic Laboratory (AAL) is to study the thermo-acoustic effect under laboratory conditions and to develop appropriate detection methods. Central element is a large volume (3 m{sup 3}) of ice or water in which sensor and emitter elements are deployed. Thermo-acoustic signals are generated by a pulsed laser beam injected into the volume. In this talk we present the experimental setup and measurements of the laser induced thermo-acoustic sound waves. In addition to these laboratory measurements an outlook on future in-situ measurements of acoustic signals in ice will be given.

    Metal active gas welding (MAG) is a widely-used welding technique resulting in high emissions of welding fume particles. This study investigated whether short-term exposure to these fume particles results in changes in lung function and early stages of inflammatory reactions. Twelve healthy, young male subjects were exposed to MAG fumes for 6 h with three different exposure concentrations in a three-fold cross-over study design. Exposure was performed in the "Aachen Workplace Simulation Laboratory" under controlled conditions with constant fume concentration. Fume concentrations were 0, 1, and 2.5 mg m(-3) in randomized order. Before and after each exposure, spirometry, and impulse oscillometry were performed and breath condensate samples were collected in order to quantify inflammatory markers like Nitrate, Nitrite, Nitrotyrosine, Hydroxyprolin and Malondialdehyde. A significant dependency on the exposure concentration could not be established for any of the endpoint parameters. In healthy, young subjects neither changes in spirometry nor changes in inflammatory markers measured in exhaled breath condensate could be detected after short-term exposure.

    Full Text Available Loss of function of dimeric glucose-6-phosphate dehydrogenase (G6PD represents the most common inborn error of metabolism throughout the world affecting an estimated 400 million people. In Germany, this enzymopathy is very rare.On the basis of G6PD crystal structures, we have analyzed six G6PD variants of German ancestry by three-dimensional modeling. All mutations present in the German population are either close to one of the three G6P or NADP(+ units or to the interface of the two monomers. Two of the three mutated amino acids of G6PD Vancouver are closer to the binding site of NADP(+. The G6PD Aachen mutation is also closer to the second NADP(+ unit. The G6PD Wayne mutation is closer to the G6P binding region. These mutations may affect the binding of G6P and NADP(+ units. Three mutations, i.e. G6PD Munich, G6PD Riverside and G6PD Gastonia, lie closer to the interface of the two monomers. These may also affect the interface of two monomers.None of these G6PD variants share mutations with the common G6PD variants known from the Mediterranean, Near East, or Africa indicating that they have developed independently. The G6PD variants have been compared with mutants from other populations and the implications for survival of G6PD variants from natural selection have been discussed.

    A comprehensive language test battery (Aachen Aphasia Test) was administered to 45 patients in the early, middle or later stages of Huntington's disease (HD) and to 20 control subjects. In spontaneous speech, many HD patients exhibited a loss of conversational initiative. Dysarthria was a common finding. Reading skills were found to be impaired mainly as a consequence of dysarthria; some HD patients displayed visual dyslexia. In addition to the characteristic disturbances of writing skills due to the choreiform movement disorder, the writing of HD patients with advanced dementia indicated constructional dysgraphia, characterized by frequent omissions, perseverations and substitutions. HD patients exhibited no evidence of word-finding difficulty or other semantic deficits in spontaneous speech. There was, however, a marked impairment in visual confrontation naming, with a significant rise in naming error rate as the disease progressed in severity. In most instances, the inappropriate names referred to an object visually similar to the target object, suggesting that visual misperception is the major cause of the naming disorder in HD. Syntactical structure of spontaneous speech was typically reduced to short, simple sentence construction. Verbal stereotypes were only rarely encountered and occurred late in the course of the disease. Tests of language comprehension reflected the general degree of dementia. It is concluded that there are no primary language changes in HD. Instead, a variety of language impairments develop secondary to other neurological and neuropsychological changes.

    Aphasia is a complex disorder, frequent after stroke (with an incidence of 38%), with a detailed pathophysiological characterization. Effective approaches are crucial for devising an efficient rehabilitative strategy, in order to address the everyday life and professional disability. Several rehabilitative procedures are based on psycholinguistic, cognitive, psychosocial or pragmatic approaches, including amongst those with a neurobehavioral approach the Melodic Intonation Therapy (MIT). Van Eeckhout's adaptation of MIT to French language (Melodic-Rhythmic Therapy: MRT) has implemented the training strategy by adding a rhythmic structure reproducing French prosody. The purpose of this study was to adapt MRT rehabilitation procedures to Italian language and to verify its efficacy in a group of six chronic patients (five males) with severe non-fluent aphasia and without specific aphasic treatments during the previous 9 months. The patients were treated 4 days a week for 16 weeks, with sessions of 30-40 min. They were assessed 6 months after the end of the treatment (follow-up). The patients showed a significant improvement at the Aachener Aphasie Test (AAT) in different fields of spontaneous speech, with superimposable results at the follow-up. Albeit preliminary, these findings support the use of MRT in the rehabilitation after stroke. Specifically, MRT seems to benefit from its stronger structure than the available stimulation-facilitation procedures and allows a better quantification of the rehabilitation efficacy.

    We examined the outcome of a 1-month intensive treatment block for people with chronic aphasia. The selected participants were eight chronically impaired people (mean months post-onset [MPO], 34). We conducted pre- and post-treatment assessments using the English-language version of the Aachen Aphasia Test (EAAT) and the Communicative Effectiveness Index (CETI). The group had significant overall improvement following treatment, which was maintained for 1 month, most significant changes seen on the EAAT were mainly in naming, comprehension, and reading and writing. Improvement was also observed on the CETI. Individual responses to treatment were variable, with some participants making more progress than others. Although the more mildly aphasic participant made most gains overall, the most severe and oldest participant made the most gains. We observed significant improvement in some subtests for some participants 1 month after treatment had ceased, suggesting a delayed effect of treatment. We conclude that short-term blocks of intensive treatment for chronically aphasic individuals can be effective.

    A computer image of a cosmic ray traversing the many layers of the TEC+ silicon sensors. The first cosmic muon tracks have been observed in one of the CMS tracker endcaps. On 14 March, a sector on one of the two large tracker endcaps underwent a cosmic muon run. Since then, thousands of tracks have been recorded. These data will be used not only to study the tracking, but also to exercise various track alignment algorithms The endcap tested, called the TEC+, is under construction at RWTH Aachen in Germany. The endcaps have a modular design, with silicon strip modules mounted onto wedge-shaped carbon fibre support plates, so-called petals. Up to 28 modules are arranged in radial rings on both sides of these plates. One eighth of an endcap is populated with 18 petals and called a sector. The next major step is a test of the first sector at CMS operating conditions, with the silicon modules at a temperature below -10°C. Afterwards, the remaining seven sectors have to be integrated. In autumn 2006, TEC+ wil...

    To assess the association between socioeconomic status (SES) and childhood obesity, and which factor in particular stands out in relation to obesity. When 2020 children attended their obligatory health exam prior to school entry in the City of Aachen, Germany, 1979 parents (97.9%) filled out a questionnaire on their child's weight development and on indicators of their family's SES in a cross-sectional survey. In addition, standardized measures of weight and height were taken. More detailed information on several different SES variables, such as parental education, occupation, income, family constellation, single parenthood, and the location and size of the family residence was obtained by personal interviews in a subsample of all native German speaking children with a BMI > or = 85th percentile, defined as cases (n = 146), and with a BMI between the 40th and 60th percentile, defined as controls (n = 221). The indicators of parental education were most strongly associated with children's obesity. There was a strong dose-response relationship between a composed index of social class and obesity. Children of the lowest social status had a more than three-fold risk to be obese than children of the highest social status in the screening population (OR: 3.29, CI: 1.92-5.63). The findings established a strong relationship between parental years of education and childhood obesity. Prevention and treatment programs should endeavor to better target undereducated parents and their young children at high risk.

    Full Text Available This contribution focuses on two PhD projects, which are integrated within the collaborative research centre 806 “Our way to Europe” at the University of Cologne and the RWTH Aachen University (Germany. The main research focus is the migration of anatomical modern human (AMH to Europe. We concentrate on the paleoenvironmental conditions on the route through southeastern Europe. This links the region with the earliest fossils of Homo sapiens sapiens (so far known in the Middle East, Anatolia, the Northwestern Black Sea, the Balkans and the Pannonian Basin. One PhD topic deals with the sedimentological and geochemical approach mainly from loess and loess-like sediments to reconstruct the paleoenvironmental conditions; the other PhD topic places an emphasis on the exact timing of those sedimentary records via luminescence dating. In particular the investigation of loess-paleosol sequences plays a central role. Geoarchives in Hungary, Serbia and Romania are of main interest for the project. The investigations will focus mainly on the loess and loess like sediments. However, data will be compared to further geoarchives, such as lacustrine sediments, speleothemes and marine records, to get a complete insight into the climatic evolution. First analyses include the loess-paleosol sequences at Bodrogkereztúr (Hungary, east of Miskolz, Orlovat (Serbia, north of Belgrade, Ságvár (Hungary, southeast of Lake Balaton, and Stalać (Serbia, confluence of South and West Morava.

    Surface barrier particle detectors, processed in Aachen using SI GaAs from several manufacturers, have been irradiated with neutrons (peak energy ˜1 MeV) up to fluences of 4.0 × 10 14 n/cm 2 and with photons from a 60Co source with a dose of 100 Mrad. All detectors work well after the irradiation. Detectors biased with 200 V during the neutron irradiation show no significant difference from those not biased. After irradiation with 4.0 × 10 14 n/cm 2 the leakage currents at 200 V are a factor of 4 greater than those before irradiation. At the highest radiation level the signal for minimum ionizing particles corresponds to 7200 electrons (at 200 V bias voltage) independent of peaking times between 40 ns and 2.2 μs. The signals for α-particles (2.2 μs peaking time, 200 V bias voltage) are about 20% of those before irradiation. The exposure to the 100 Mrad photon dose caused little change of the detector performance. The leakage currents were even reduced by about 10%.

    Ventricular assist devices for small pediatric patients are expensive and commercially unavailable in Taiwan. We used the Medos ventricular assist device cannula (Medos, Aachen, Germany) and a centrifugal pump to support pediatric patients with dilated cardiomyopathy and decompensated heart failure. From January 2007 to December 2008, three pediatric patients with dilated cardiomyopathy were supported using a centrifugal pump as the left ventricular assist device. The Medos arterial cannula was sutured to the ascending aorta, and the Apex cannula was fixed into the left ventricular apex. When the patient was weaned off of cardiopulmonary bypass, the left ventricular assist device pump was started. The pump flow was gradually titrated according to the filling status of the left ventricle. All the left ventricular assist devices were successfully implanted and functioned well. Two patients on extracorporeal membrane oxygenation had severe lung edema before left ventricular assist device implantation. Both patients required extracorporeal membrane oxygenation for the postoperative period until the pulmonary edema was resolved. Among the three patients, two successfully bridged to heart transplantation after support for 6 and 11 days, respectively. The first patient (10 kg) expired due to systemic emboli 30 days after left ventricular assist device support. In summary, these results suggest that the Medos ventricular assist device cannula and a centrifugal pump is an option for temporary left ventricular assist device support in patients with intractable heart failure and as a bridge to heart transplantation.

    2017 marks the 90th birthday of the invention of the first RF linear accelerator which was built in Aachen, Germany. Published in Rolf Wideroe’s ground-breaking 27 page PhD thesis, the rf linear accelerator has opened up new windows of science ever since. Most remarkably though, the invention was made by a man who at the age of 20, just five years before, also invented the betatron and wrote down the famous “Wideroe Equation”. The talk will go over the fascinating live of a man and his family who has been driven by science. A man who either was involved or single handedly invented many of the accelerator technologies that we use in our community today. While following Rolf Wideroe through much of the last century, the talk will also address his inventions and the impact they made. - The science story of accelerators is embedded in the historic context of Rolf Wideroe’s family, his parents, brothers and sisters and the time he was living. Much of this story is based on a book recently published by Aash...

    To investigate the prevalence of overweight according to nationality in preschool children living in Germany, and to establish the determinants responsible for differences in body mass index. The study was performed within the context of the 2001/2002 obligatory health examination before school entry in the city of Aachen, Germany. Of 2020 eligible children 1979 children were recruited (participation rate: 98%). Children's height and weight were measured using a standardised protocol. The parents completed a standardised questionnaire on sociodemographic factors and possible determinants of nutritional status. Being overweight was defined according to age and sex specific reference values for German children as well as according to international reference values. The study population included 452 (22.9%) children with other than German nationality. Among these children the prevalence of overweight was twice as high than among German children (14.8% v 7.2%). Prevalence of most known risk factors for overweight, such as low physical activity, high consumption of soft drinks, and frequent visits to fast-food restaurants was higher in the children with other nationalities than in the German children. Multivariate analyses revealed that most of the difference in prevalence of obesity by nationality is explained by known risk factors of overweight, especially education of mother and watching TV. The apparent ethnic differences could be explained by two non-ethnic but socioeconomic factors. In preventing overweight in children, there is the need to identify and deal with high risk environments rather than high risk ethnic groups.

    GaAs strip and pixel detectors constructed in Aachen have been tested in a 1.4 GeV electron beam in Bonn and in a 5 GeV electron beam at DESY in February and May 1997. The strip detectors had a pitch of 50 {mu}m with a strip width of 25 {mu}m and were made of a 250 {mu}m thick Freiberger SI-GaAs wafer. The strip detectors included a punch-through bias structure and an integrated coupling capacitor. Additionally, an improved backside contact was formed, allowing a safe operation of the detector in a soft breakdown regime. Using the fast PreMux128 preamplifier multiplexer chip ({tau}{sub p}=50 ns) a signal-to-noise ratio of 13 was obtained at normal beam incidence for a bias voltage of 200 V, leading to a spatial resolution of 11 {mu}m with a simple COG algorithm. The 8 x 16 pixel array with a pixel size of 125 x 125 {mu}m{sup 2} was read out with the PreMux128 as well. With a double-metal technique, it was possible to bond the single-pixels linearly to the amplifier chip. The obtained signal-to-noise ratio of 30 in combination with a COG algorithm lead to the digital resolution value of 36 {mu}m for both pixel coordinates. (orig.) 10 refs.

    Surface barrier detectors processed in Aachen using semi-insulating (SI) GaAs from several manufacturers have been irradiated with high fluences of neutrons (mean energy 1 MeV, fluence up to {Phi}{sub n} {proportional_to} 5 x 10{sup 14} cm{sup -2}), pions (191 MeV, fluence up to {Phi}{sub {pi}} {proportional_to} 0.6 x 10{sup 14} cm{sup -2}) and protons (23 GeV, fluence up to {Phi}{sub p} {proportional_to} 2 x 10{sup 14} cm{sup -2}). The detectors have been characterized in terms of macroscopic quantities like I-V characteristic curves and charge collection efficiencies for incident minimum ionizing- (mip) as well as {alpha}-particles. All detectors work well after the exposure. At the highest fluences a sizable degradation in the charge collection efficiencies has been observed for all investigated materials. SI-GaAs material with low carbon (LC) content seems to be less affected than substrates with a higher carbon concentration. At the highest irradiation level the mip signal from a 250 {mu}m thick detector made of LC material amounts to 8000 electrons (at 400 V bias voltage) independent of peaking times between 40 ns and 2.2 {mu}s. The leakage currents for this material are even reduced after the irradiation. (orig.).

    A GaAs pixel detector constructed in Aachen has been tested in a 4 GeV electron beam at DESY. The experimental setup allowed tilting the detector with respect to the beam line with angles of incidence from 0 deg. to 45 deg. . The sensor-array consisted of 8 x 16 pixels with a size of 125 x 125{mu}m{sup 2} each. The detector was made of a 250{mu}m thick Freiberger SI-GaAs wafer. An improved contact was formed on the backside, allowing safe operation of the detector in the soft breakdown regime. A double metal technique allowed bonding the single pixels linearly to the readout-chip. Using the the fast PreMux128 preamplifier multiplexer chip ({tau}{sub p} = 40ns) a signal to noise ratio of 29 was obtained for a beam angle of incidence of 0 deg. increasing up to 38 for 45 deg. The spatial resolution obtained with an angle of incidence of 45 deg. was (9.0 {+-} 6.0){mu}m while the resolution of the untilted detector is equal to the digital one (36.1{mu}m). For these testbeam-measurements the detector was connected to the electronics via wire-bonds. For future experiments bump-bonding connections are required. The results of a process for the formation of bump-bond connections on GaAs pixeldetectors are shown.

    Surface barrier detectors processed in Aachen using SI-GaAs from several manufacturers have been irradiated with high fluences of neutrons (mean energy 1 MeV, fluence up to {Phi}{sub n}{proportional_to}5 x 10{sup 14} cm{sup -2}), pions (191 MeV, fluence up to {Phi}{sub {pi}}{proportional_to}0.6 x 10{sup 14} cm{sup -2}) and protons (23 GeV, fluence up to {Phi}{sub p}{proportional_to}2 x 10{sup 14} cm{sup -2}). The detectors have been characterized in terms of macroscopic quantities like I-V characteristic curves and charge collection efficiencies for incident minimum ionizing- (mip) as well as {alpha}-particles. All detectors work well after the exposure. At the highest fluences a sizable degradation concerning the charge collection efficiencies has been observed for all investigated materials. SI-GaAs material with low carbon content (LC material from FCM, Freiberg) seems to be less affected than substrates with a higher carbon concentration. At the highest irradiation level the mip signal from a 250 {mu}m thick detector made of LC material amounts to 8000 electrons (at 400 V bias voltage) independent of peaking times between 40 ns and 2.2 {mu}s. The leakage currents for this material are even reduced after the irradiation. (orig.).

    Full Text Available Korpus er en type digitale språkressurser (maskinlesbare tekstsamlinger som er mye brukt i moderne lingvistikk som empirisk støtte for studiet av ulike språklige fenomener. Korpus kan med hell brukes i fremmedspråkundervisningen, men er frem til nå ikke i tilstrekkelig grad blitt tatt i bruk i norsk skole og høyere utdanning. I denne artikkelen gir vi en gjennomgang av eksisterende forskningslitteratur på feltet, med hovedvekt på bidrag fra det angloamerikanske språkområdet. Deretter går vi gjennom to korpus som er tilgjengelige for norske brukere, Norwegian-Spanish Parallel Corpus og Oslo Multilingual Corpus. Vi viser hvordan disse korpusene kan brukes i undervisningen av ulike språklige fenomener, fra vokabular til sosiolingvistiske fenomener. På grunnlag av eksisterende forskning på pedagogiske applikasjoner av korpus samt våre egne forslag til undervisningsopplegg er det grunn til å tro at bruk av korpus vil kunne være et verdifullt bidrag til fremmedspråkundervisningen i norske klasserom. Likevel finnes visse utfordringer som hindrer at korpus tas i bruk. Både mangel på tid, gruppestørrelser og teknologiske hindre kan stå i veien. Bruk av korpus i fremtidens klasserom er også nært knyttet til ulike trender, både innenfor teknologi og forskning. For det først blir datateknologi stadig mer tilgjengelig, parallelt med at elevenes og studentenes digitale kompetanse øker. Dette er fenomener som begge skulle tilsi økt bruk av korpus. Videre er det en sterk bevegelse for å åpne opp tilgang til forskningsdata og –ressurser (Open Access og denne bølgen kan også brukes til å åpne opp forskningsressurser, herunder korpus, for læringsformål. Til syvende og sist er spørsmålet om bruk av korpus i klasserommet imidlertid avhengig av en tettere dialog mellom lærere og korpuslingvister, både i lærerutdanningen så vel som gjennom faglig oppdatering underveis i yrkeslivet.

    Full Text Available Å være lærerutdanner skiller seg fra andre stillinger innenfor høyere utdanning: Lærerutdanneren underviser både i fagstoff og i hvordan studentene kan lære bort og adaptere fagstoffet i klasserommet. Det at lærerutdanneren underviser i det å undervise, har implikasjoner for hvordan undervisningen planlegges, gjennomføres og analyseres i lærerutdanningen – undervisningens form blir en del av budskapet. Lærerutdannerens arbeid handler derfor om å utforme, velge og sette i spill aktiviteter og oppgaver som kan adaptere fag, forskning, didaktikk og teori til klasserom og profesjonen. Utforming og montasje av de ulike delene eller episodene i et undervisningsforløp kan betegnes som undervisningsforløpets dramaturgi. I denne artikkelen har jeg gjort en dramaturgisk analyse av tre lærerutdanneres undervisning for å identifisere og beskrive hvordan de bruker eksplisitte modelleringsformer, og hva som skjer når de bruker dem. I etterkant av den dramaturgiske analysen har jeg gjort en konvensjonell innholdsanalyse av intervjudata for å undersøke hvordan lærerutdannerne selv forklarer formålet og erfaringer med å bruke eksplisitt modellering i undervisningen. Analyse av tre lærerutdanneres undervisningspraksis sammenfattes i en modelleringsstige som visualiserer hvordan enkelte former for eksplisitte modelleringsformer tilbyr en egen sirkulær dramaturgi. Studien antyder og drøfter også på hvilken måte modelleringsstigen kan fungere som en dramaturgisk modell, som kan brukes som utgangspunkt for lærerutdanneres planlegging, gjennomføring og analyse av egen undervisning. Studien er et bidrag til å utvikle og forske på hvordan eksplisitte modelleringsformer kan brukes for å skape sammenheng mellom praktisk lærerarbeid og teoretisk metarefleksjon i lærerutdannerens undervisning. Innsamling av data er gjort i profesjonsverksted, som kan forklares som en læringsarena hvor lærerutdannere fra ulike fag samarbeider om

De recente veranderingen vereisen (opnieuw aandacht in onder andere onderzoek en onderwijs. In dit artikel reflecteren we op de ideologie en doelen die schuilen achter de transitie in Nederland en linken we deze naar het onderzoek en onderwijs dat georganiseerd wordt door het lectoraat Community Care. Wat betekent het “nieuwe denken” van de transitie voor het Community Care gedachtegoed in relatie tot onderwijs en onderzoek? Het lectoraat Community Care van de Hogeschool van Amsterdam houdt zich bezig met verschillende onderzoeksonderwerpen verdeeld onder drie stromingen: informele zorg, sociale inclusie en netwerkversterking. Binnen deze drie onderzoekslijnen wordt er gefocust op zorg door de samenleving en hoe dit gelinkt kan worden aan professionele zorg. In dit artikel zetten we uiteen waarom dit relevant is in onderzoek en onderwijs, zeker wanneer de transitie in Nederland eens temeer benadrukt dat zorg in en door de samenleving belangrijk is, en de rol van de zorgprofessional verandert. Tot slot reflecteren we op de manieren waarop we dit gedachtegoed en het huidige zorgbeleid kunnen vertalen in onderwijs voor studenten die later in het sociaal- en zorgdomein werkzaam zullen zijn. Community Care and the Care Transition in the NetherlandsThe transition taking place within the Dutch healthcare system has been a central theme in politics and public debate for decades.

Im Artikel ist beschrieben, wie diese Fotosammlung im 19. Jahrhundert zu Stande gekommen ist. Daneben werden die damaligen Fotografen in Tartu vorgestellt.Es ist bekannt, dass erste Wanderfotografen das Gebiet des heutigen Estlands im Jahre 1843 erreichten, erste Nachrichten von Fotografen in Tartu stammen aus dem Jahr 1844. Dennoch hat die GEG erst in der Mitte der 1850er Jahren angefangen, Fotografien oder Lichtbilder gezielt zu sammeln. In den 1850er Jahren sind insgesamt nur drei Fotos aufgenommen worden; und Anfang der 1870er Jahre besaß das Museum der GEG dann nur etwa 30 Fotografien. Von diesen sind von den Tartuer Fotografen selbst mehr als 20 Fotos dem Museum gestiftet worden. Auch in den folgenden Jahrzehnten sind nur einzelne Fotos vom Museum gesammelt worden. Obwohl die Mitglieder der GEG sich mehrfach dafür aussprachen, dass man die lokale Kultur auch fotografisch festhalten sollte, folgten von Seiten der GEG keine bemerkenswerten Unternehmungen in dieser Sache.Heute sind die meisten der im 19. Jahrhundert gesammelten und aus dem Museum der GEG stammenden Fotos im Estnischen Historischen Museum gut erhalten. Insgesamt sind es mehr als 1600 Fotos, die aus dem Museum der GEG ins Estnische Historische Museum übernommen wurden, darunter auch Aufnahmen aus dem 20. Jahrhundert.

    2011-01-01

    In 2007 a new project has been launched in a cooperation between the RWTH Aachen Physics Department, the University Hospital Aachen and the Philips Research Laboratories. The project aim is to validate and improve GEANT4 nuclear interaction models for use in proton and ion therapy. The method chosen here is the measurement of nuclear reaction cross sections which will not only provide a comparison to the simulation but will also allow to improve some of the parameters in the nuclear models. In the first phase of the project 200 MeV protons are used as a projectile in combination with a thin graphite target. For use in particle therapy the excitation functions of the most frequently produced isotopes need to be measured with an accuracy of 10% or less. For this purpose a dedicated detector system has been designed and implemented in GEANT4. The detection of target fragments produced by protons in graphite is achieved via time-of-flight spectrometry. In the setup presented here the primary beam first hits the Start detector and initiates the time-of-flight measurement before it passes through the apertures of two Veto detectors and impinges on the target. Successively, the secondary particles emanating from the target travel a short distance of 70/80 cm through vacuum (0.1 mbar) before they hit one of the 20 Stop detectors which end the time-of-flight measurement and record the energy deposited by the particle. The dissertation at hand describes the underlying detector concept and presents a detailed GEANT4 simulation of the setup which allows to evaluate the detector performance with respect to target fragment identification at a projectile energy of 200 MeV. At first, correlations of time-of-flight and energy deposition are built from simulated data and are subsequently used to reconstruct mass spectra of the detected fragments. Such influences on the detection performance as the target thickness, the residual pressure within the detector chamber, the Veto system

    As in other research areas, the information flood is rising quickly in the field of non-ionizing radiation. The number of scientific publications regarding the effects of high- and low-frequency fields is estimated to exceed 20.000. With help of modern information management techniques it is possible to acquire all available information and to retrieve relevant data instantly. The knowledge-based literature database on the effects of electromagnetic fields on the organism (WBLDB) is intended to become a comprehensive information portal in the area of bioelectromagnetic interaction. Unlike conventional literature databases which collect only bibliographical data of the relevant studies, our database is set up according to the structure of scientific publications in order to represent all important data included in the original text. For a fast extension of the knowledge base it is crucial that the tool is widely accepted. In order to provide the included information not only for experts but also for politicians, jurists and the public, the development of a set of search and query tools for different target audiences is desirable. This is achieved by establishing different search and presentation techniques. There is free and unrestricted access to the information system at http://www.femu.rwth-aachen.de. Although under development, the site is accessed up to 10,000 times per week. (orig.)

CITY 2020+ develops scenarios, options and tools for planning and developing sustainable future city structures. We investigate how urban environment, political structure and residential behavior can best be adapted, with attention to the interactions among structural, political, and sociological configurations and with their consequences on human health. Demographers project that in the EU-25-States by 2050, approximately 30% of the population will be over age 65. Also by 2050, average tem¬peratures are projected to rise by 1 to 2 K. Combined, Europe can expect enhanced thermal stress and higher levels of particulate matter. CITY 2020+ amongst other sub-projects includes research project dealing with (1) a micro-scale assessment of blockages to low-level cold-air drainage flow into the city centre by vegetation and building structures, (2) a detailed analysis of the change of probability density functions related to the occurrence of heat waves during summer and the spatial and temporal structure of the urban heat island (UHI) (3) a meso-scale analysis of particulate matter (PM) concentrations depending on topography, local meteorological conditions and synoptic-scale weather patterns. First results will be presented specifically from sub-projects related to vegetation barriers within cold air drainage, the assessment of the UHI and the temporal and spatial pattern of PM loadings in the city centre. The analysis of the cold air drainage flow is investigated in two consecutive years with a clearing of vegetation stands in the beginning of the second year early in 2010. The spatial pattern of the UHI and its possible enhancement by climate change is addressed employing a unique setup using GPS devices and temperature probes fixed to

    Reducing the secondary losses in the bladed annulus of compressors and turbines is one approach to enhance the efficiency of turbo components of modern gas turbines. The aim of this project is to analyse the influence of endwall contouring and 3D airfoil design in the endwall region on the generation of secondary flows in a multistage low pressure turbine. Therefore experimental studies were carried out in a three stage cold flow test rig. First in a reference blading the flow fields in the axial gapes between the rows were conducted with pneumatic probes and with a 3D-L2F system (DLR Koeln) and with 3D hot wire probes (RWTH Aachen) by the project partners. Pressure distributions on several stram line positions and endwall pressure measuring points are employed to assess the vane flow. In a second phase the inlet guide vanes and the blades of the first rotor were replaced with a blading with endwall contouring and modified airfoilds in the endwall region, which was designed by the project partner MTU. The investigations were carried out in the same manner as before. In comparison to the results of the reference blading the secondary losses in the plane downstream the optimised inlet guide van could be reduced about 20% in the outer region. A reduction in the secondary flow phenomen, the passage vortex, can be traced back to reduced cross channel pressure gradients at the endwall. The secondary losses in the tip region could be moved closer to the casing. After the following rows downstream the optimised first turbine stage there was no positive influence on the development of secondary flows detectable. A data base was generated to validate and to improve current numerical methods. The physical understanding of secondary flows in multistage turbines was deepened. (orig.)

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.

    Several islands in the northfrisian part of the UNESCO - World Natural Heritage Wadden Sea are exposed to extreme storm surges due to climate change and sea level rise. Existing coastal protection measures in this area do not consider the future sea state and are mainly based on tradition and expert knowledge. The two projects HoRisK and ZukunftHallig (supported by the German Coastal Engineering Research Council) focus on this area and implement the requirements defined in the Directive 2007/60/EC on the assessment and management of flood risk. The main objects of the projects are the design and evaluation of new coastal protection techniques for the investigation area. With numerical simulations hydrological parameters are investigated in order to design new coastal protection- and management strategies. The decision support system PROMAIDES (Protection Measure against Inundation Decision Support) developed at the Institute of Hydraulic Engineering and Water Resources Management of the RWTH Aachen University analyzes the effects and reliability of new coastal protection techniques and evaluates inundation areas and economic damages for different hydrological boundary conditions. As a result flood risk and hazard maps are shown in this work. Furthermore sensitivity analyses expose possible variations in future storm surges and illustrate the difference in significant wave heights for varying wind climates. This risk based approach of both projects is a suitable way to ensure life for further generations on these islands under sustainable ecological und economic conditions.

  10. Shared neural substrates of apraxia and aphasia.

    2015-08-01

    Apraxia is regularly associated with aphasia, but there is controversy whether their co-occurrence is the expression of a common basic deficit or results from anatomical proximity of their neural substrates. However, neither aphasia nor apraxia is an indivisible entity. Both diagnoses embrace diverse manifestations that may occur more or less independently from each other. Thus, the question whether apraxia is always accompanied by aphasia may lead to conflicting answers depending on which of their manifestations are considered. We used voxel based lesion symptom mapping (VLSM) for exploring communalities between lesion sites associated with aphasia and with apraxia. Linguistic impairment was assessed by the Aachen Aphasia Test (AAT) subtests naming, comprehension, repetition, written language, and Token Test. Apraxia was examined for imitation of meaningless hand and finger postures and for pantomime of tool use. There were two areas of overlap between aphasia and apraxia. Lesions in the anterior temporal lobe interfered with pantomime of tool use and with all linguistic tests. In the left inferior parietal lobe there was a large area where lesions were associated with defective imitation of hand postures and with poor scores on written language and the Token Test. Within this large area there were also two spots in supramarginal and angular gyrus where lesions were also associated with defective pantomime. We speculate that the coincidence of language impairment and defective pantomime after anterior temporal lesions is due to impaired access to semantic memory. The combination of defective imitation of hand postures with poor scores on Token Test and written language is not easily compatible with a crucial role of parietal regions for the conversion of concepts of intended actions into motor commands. It accords better with a role of left inferior parietal lobe regions for the categorical perception of spatial relationships. Copyright © 2015 Elsevier Ltd. All

    Full Text Available A range of methods in clinical research aim to assess treatment-induced progress in aphasia therapy. Here, we used a crossover randomized controlled design to compare the suitability of utterance-centered and dialogue-sensitive outcome measures in speech-language testing. Fourteen individuals with post-stroke chronic non-fluent aphasia each received two types of intensive training in counterbalanced order: conventional confrontation naming, and communicative-pragmatic speech-language therapy (Intensive Language-Action Therapy, an expanded version of Constraint-Induced Aphasia Therapy. Motivated by linguistic-pragmatic theory and neuroscience data, our dependent variables included a newly created diagnostic instrument, the Action Communication Test (ACT. This diagnostic instrument requires patients to produce target words in two conditions: (i utterance-centered object naming, and (ii communicative-pragmatic social interaction based on verbal requests. In addition, we administered a standardized aphasia test battery, the Aachen Aphasia Test (AAT. Composite scores on the ACT and the AAT revealed similar patterns of changes in language performance over time, irrespective of the treatment applied. Changes in language performance were relatively consistent with the AAT results also when considering both ACT subscales separately from each other. However, only the ACT subscale evaluating verbal requests proved to be successful in distinguishing between different types of training in our patient sample. Critically, testing duration was substantially shorter for the entire ACT (10–20 min than for the AAT (60–90 min. Taken together, the current findings suggest that communicative-pragmatic methods in speech-language testing provide a sensitive and time-effective measure to determine the outcome of aphasia therapy.

    Neodymium and dysprosium are two rare earth elements (REEs), out of a group of 17 elements with similar chemical properties. Due to their unique properties, REEs gained increasing importance in many new technologies like wind turbines, batteries, lighting, and medical technique. However, the production of REEs requires high material and energy consumption and is associated with considerably environmental burdens e.g. radioactive loaded dust and tailings. Due to the Chinese hegemony regarding REE production and the strong dependency of European industry on Chinese REE exports this paper presents a possible European production chain of REEs based on the mineral Eudialyte found in Norra Karr (Sweden). Because almost 90% of the total mines production of 109,000 t REO equivalents in 2013 [USGS, 2013] occurred in China, the European production is compared to the Chinese route. Bayan Obo is the largest REE deposit in China located near Baotou in Inner Mongolia. Using the Life Cycle Assessment method (LCA), the environmental impacts of both production lines are assessed. Although LCA is a well-known methodology to determine environmental aspects from cradle-to-grave, there are only a few LCA studies available considering REE production, almost all based on process information gathered in the 1990s. This study presents newly estimated data of a possible European Eudialyte based production route collected in a corporate 4-year project together with Siemens AG, RWTH Aachen University and Forschungszentrum Julich. The results for the new European process route show reduced environmental burdens although the total REE content in Eudialyte is much smaller than in the Chinese deposit. Especially, the results for dysprosium from Eudialyte outreach those for Bayan Obo, due to the higher content of heavy rare earth elements (HREEs).

    Drug hypersensitivity reactions of immediate type pose a challenging problem, especially, if standard diagnostic procedures do not lead to conclusive results. The aim of this investigation is to identify, whether basophil activation test (BAT) is able to provide additional benefit in the diagnostic evaluation of immediate type drug hypersensitivity reactions to antibiotics in comparison to the routine allergological diagnostic methods. We investigated patients, which presented to the Department of Dermatology and Allergology of the University Hospital of RWTH Aachen in Germany for diagnostic workup of type I allergic reactions to antibiotics during the period from 2009 to 2012. The analysis was performed retrospectively based on patient records. The inclusion criteria were performed standard allergological in vivo diagnostic and a basophil activation test (BAT) as a part of diagnostic workup. 82 diagnostic investigations were performed in 52 patients. BAT was positive in 9 of 12 cases with a positive clinical history but negative skin test results. Furthermore, all patients who reported severe drug hypersensitivity reactions (anaphylactic reaction grade 2 and above) showed positive BAT (5/5), while only 3 of these 5 cases demonstrated a positive skin testing that led to the conclusion of possible immediate type drug hypersensitivity. Although skin tests remain the most important part of the primary diagnostic investigation, BAT is an additional valuable and sensitive in vitro test in the diagnostic procedure of immediate type allergic reactions to antibiotics. However, further standardized investigations are needed in order to calculate exact sensitivity and specificity of this diagnostic tool in both, adult and pediatric populations.

    The Forschungszentrum Juelich GmbH (FZJ), together with the Aachen University Rheinisch-Westfaelische Technische Hochschule (RWTH) and the French Alternative Energies and Atomic Energy Commission (CEA Cadarache) are involved in a cooperation aiming at characterizing toxic and reactive elements in radioactive waste packages by means of Prompt Gamma Neutron Activation Analysis (PGNAA). The French and German waste management agencies have indeed defined acceptability limits concerning these elements in view of their projected geological repositories. A first measurement campaign was performed in the new Prompt Gamma Neutron Activation Analysis (PGNAA) facility called MEDINA, at FZJ, to assess the capture gamma-ray signatures of some elements of interest in large samples up to waste drums with a volume of 200 liter. MEDINA is the acronym for Multi Element Detection based on Instrumental Neutron Activation. This paper presents MCNP calculations of the MEDINA facility and quantitative comparison between measurement and simulation. Passive gamma-ray spectra acquired with a high purity germanium detector and calibration sources are used to qualify the numerical model of the crystal. Active PGNAA spectra of a sodium chloride sample measured with MEDINA then allow for qualifying the global numerical model of the measurement cell. Chlorine indeed constitutes a usual reference with reliable capture gamma-ray production data. The goal is to characterize the entire simulation protocol (geometrical model, nuclear data, and postprocessing tools) which will be used for current measurement interpretation, extrapolation of the performances to other types of waste packages or other applications, as well as for the study of future PGNAA facilities.

    Heart disease is one of the leading causes of death in the world. Due to a shortage in donor organs artificial hearts can be a bridge to transplantation or even serve as a destination therapy for patients with terminal heart insufficiency. A pusher plate driven pulsatile membrane pump, the Total Artificial Heart (TAH) ReinHeart, is currently under development at the Institute of Applied Medical Engineering of RWTH Aachen University.This paper presents the methodology of a fully coupled three-dimensional time-dependent Fluid Structure Interaction (FSI) simulation of the TAH using a commercial partitioned block-Gauss-Seidel coupling package. Partitioned coupling of the incompressible fluid with the slender flexible membrane as well as a high fluid/structure density ratio of about unity led inherently to a deterioration of the stability (‘artificial added mass instability’). The objective was to conduct a stable simulation with high accuracy of the pumping process. In order to achieve stability, a combined resistance and pressure outlet boundary condition as well as the interface artificial compressibility method was applied. An analysis of the contact algorithm and turbulence condition is presented. Independence tests are performed for the structural and the fluid mesh, the time step size and the number of pulse cycles. Because of the large deformation of the fluid domain, a variable mesh stiffness depending on certain mesh properties was specified for the fluid elements. Adaptive remeshing was avoided. Different approaches for the mesh stiffness function are compared with respect to convergence, preservation of mesh topology and mesh quality. The resulting mesh aspect ratios, mesh expansion factors and mesh orthogonalities are evaluated in detail. The membrane motion and flow distribution of the coupled simulations are compared with a top-view recording and stereo Particle Image Velocimetry (PIV) measurements, respectively, of the actual pump.

    The objective of this study was to investigate whether there is a relationship between the external exposure dose of chromium and nickel caused by a metal active gas welding process with a solid high-alloyed steel welding wire and inner exposure of subjects. In order to perform welding fume exposure under controlled and standardized conditions, the investigations were conducted in the "Aachen Workplace Simulation Laboratory". To perform biological monitoring of chromium and nickel, blood and urine samples of 12 healthy male non-smokers who never worked as welders were collected before and after a 6-h exposure to ambient air (0 mg/m(3)) and to welding fumes of a metal active gas welding process once with a concentration of the welding fume of 1 mg/m(3) and once with a concentration of 2.5 mg/m(3). Although the internal exposure to chromium and nickel in this study was comparatively low, the subjects showed significantly increased concentrations of these metals in urine after exposure to welding fume compared to the values at baseline. Moreover, the observed increase was significantly dose dependent for both of the substances. For the biological monitoring of chromium and nickel in urine of subjects exposed to welding fumes, a dependency on exposure dose was seen under standardized conditions after a single exposure over a period of 6 h. Thus, this study contributes to a better understanding of the relationship between ambient and biological exposures from welding fumes and provides a good basis for evaluating future biological threshold values for these metals in welding occupation.

    The 3rd International Conference on Advances in Solidification Processes was held in the Rolduc Abbey in the Netherlands a few kilometres away from Aachen. Around 200 scientists from 24 countries come in for the four day meeting. They found a stimulating but also relaxing environment and atmosphere, with beautiful weather and the medieval abbey inviting for walks, discussions, sitting outside and drinking a beer or wine. The contributions given at the conference reflected recent advances in various topics of solidification processes, ranging from fundamental aspects to applied casting technologies. In 20 oral sessions and a large poster session innovative results of segregation phenomena, microstructure evolution, nucleation and growth, phase formation, polyphase solidification, rapid solidification and welding, casting technology, thermophysics of molten alloys, solidification with forced melt flow and growth of single crystals and superalloys together with innovative diagnostic techniques were presented. Thereby, findings from experiments as well as from numerical modeling on different lengths scales were jointly discussed and contribute to new insight in solidification behaviour. The papers presented in this open access proceedings cover about half the oral and poster presentations given. They were carefully reviewed as in classical peer reviewed journals by two independent referees and most of them were revised and thus improved according to the reviewers comments. We think that this collection of papers presented at ICASP-3 gives an impression of the excellent contributions made. The papers embrace both the basic and applied aspects of solidification. We especially wish to express our appreciation for the team around Georg Schmitz and Margret Nienhaus organising this event and giving us their valued advice and support at every stage in preparing the conference. We also thank Lokasenna Lektorat for taking the task of checking all language-associated issues and

    In Germany, more and more terminally ill patients spend their last days of life in nursing homes, and this presents a challenge for these institutions. Even though palliative care is a growing domain in health care, no quantitative in-depth evaluations of the status quo in nursing homes has been conducted so far in Germany, partly because of lacking measuring tools. This study used a new questionnaire to assess German health care professionals' theoretical knowledge of palliative care and their perceived self-efficacy. Both variables have been proven to be indicators for the quality of the implementation of palliative care in nursing homes. We used the Bonn Palliative Care Knowledge Test (Bonner Palliativwissenstest, BPW) questionnaire to measure knowledge of palliative care in the domains of medicine, care, and psychosocial care and to measure self-efficacy relating to palliative care. Care workers (N=130) in five nursing homes in the region of Aachen in western Germany answered the questionnaires. The results show low knowledge (on average 52.8% correct answers) and self-efficacy relating to palliative care, although work with dying people is their daily challenge. While general knowledge correlated with work experience, a negative correlation of specific self-efficacy with age and working experience was observed. Lower self-efficacy of care workers experienced in palliative care probably implies that the difficulty of palliative care skills is underestimated by inexperienced care workers. Palliative care training is urgently needed to improve knowledge and self-efficacy. Guidance to assist care professionals involved in palliative care in nursing homes needs to be developed and provided.

    The power supply of remote sites and applications at minimal cost and with low emissions is an important issue when discussing future energy concepts. This paper presents the modelling and optimisation of a stand-alone hybrid energy system. The system consists of photovoltaic (PV) panels and a wind turbine as renewable power sources, a diesel generator for back-up power and batteries to store excess energy and to improve the system reliability. For storage the technologies of lithium-ion, lead-acid, vanadium redox-flow or a combination thereof are considered. In order to use different battery technologies at once, a battery management system (BMS) is needed. The presented BMS minimises operation cost while taking into account different battery operating points and ageing mechanisms. The system is modelled and implemented in Matlab/Simulink. As input, the model uses data of the irradiation, wind speed and air temperature measured in ten minute intervals for ten years in Aachen, Germany. The load is assumed to be that of a rural UMTS/GSM base station for telecommunication. For a timeframe of 20 years, the performance is evaluated and the total costs are determined. Using a genetic algorithm, component sizes and settings are then varied and the system re-evaluated to minimise the overall cost. The optimisation results show that using batteries in combination with the renewables is economic and ecologic. However, the best solution is to combine redox-flow batteries with the renewables. In addition, a power supply system consisting only of batteries, PV and wind generators can satisfy the power demand.

    Combined experimental und numerical investigations of the turbulent wake of a generic space launcher at transonic free stream conditions (Ma∞ = 0.7 and ReD = 1.0 · 106) are performed to gain a better understanding of intricate phenomena of the wake flow physics and to validate new methods for its analysis. The experiments are conducted at the Bundeswehr University Munich using a high-repetition-rate particle image velocimetry (PIV) system, while the numerical investigation is performed by the Institute of Aerodynamics of RWTH Aachen University using a zonal Reynolds-averaged Navier-Stokes (RANS) / large-eddy simulation (LES) approach. After a characterization of the wake flow topology, two applied methodologies are compared to each other with respect to the spatial and temporal resolution stressing their strengths and shortcomings. It is shown that both methods are well suitable for the prediction of the mean and instantaneous values of the turbulent velocity field, whereas for a reliable statistical analysis of the velocity fluctuations, the PIV approach is more appropriate due to the computational time limitations of the LES. On the other hand, the high spatial and temporal resolution of the LES allows for an accurate detection of relevant coherent structures as well as tracking their motion in time without any significant artificial vortex agglomeration that can be critical in the case of PIV. Furthermore, the influence of different model assumptions, e. g., the level of incoming turbulence and model vibrations, is discussed in order to emphasize the importance of a side-by-side combination of both investigation techniques.

    Full Text Available Hiltrud Liedgens,1 Marko Obradovic,1 Mark Nuijten2 1Grunenthal GmbH, Aachen, Germany; 2Ars Accessus Medica, Amsterdam, the Netherlands Background: Post-herpetic neuralgia (PHN is the most common and most debilitating complication of herpes zoster, and involves considerable associated costs. Objective: This paper presents results from nine health economic studies undertaken in eight European countries that compared lidocaine medicated plaster with gabapentin and/or pregabalin in PHN. It aims to support the increasing need for published cost-effectiveness data for health care decision-making processes in Europe. Methods: All studies were based on a similar core Markov model with data derived from clinical trials, local Delphi panels, and official national price and tariff lists. The main outcome measure was cost per quality-adjusted life year gained; time without pain or intolerable adverse events was also included as a secondary outcome measure. All studies focused on an elderly population of patients with PHN who had insufficient pain relief with standard analgesics and could not tolerate or had contraindications to tricyclic antidepressants. Results: Despite considerable differences in many of the variables used, the results showed remarkable similarity and suggested that use of lidocaine medicated plaster offered cost-savings in many of the countries studied, where it proved a highly cost-effective alternative to both gabapentin and pregabalin. Conclusion: Lidocaine medicated plaster is a cost-effective alternative to gabapentin and pregabalin in the treatment of PHN. These savings are largely the result of the superior safety profile of the lidocaine medicated plaster. Keywords: post-herpetic neuralgia, zoster, cost-effectiveness, lidocaine, plaster

    Full Text Available Perioperative preservation of renal function has a significant impact on morbidity and mortality in kidney surgery. Nephroprotective effects of the anesthetic xenon on ischemia-reperfusion injury were found in several experimental studies.We aimed to explore whether xenon anesthesia can reduce renal damage in humans undergoing partial nephrectomy and to gather pilot data of possible nephroprotection in these patients.A prospective randomized, single-blinded, controlled study.Single-center, University Hospital of Aachen, Germany between July 2013-October 2015.Forty-six patients with regular renal function undergoing partial nephrectomy.Patients were randomly assigned to receive xenon- (n = 23 or isoflurane (n = 23 anesthesia.Primary outcome was the maximum postoperative glomerular filtration rate (GFR decline within seven days after surgery. Secondary outcomes included intraoperative and tumor-related data, assessment of further kidney injury markers, adverse events and optional determination of renal function after 3-6 months.Unexpected radical nephrectomy was performed in 5 patients, thus they were excluded from the per-protocol analysis, but included in the intention-to-treat analysis. The maximum postoperative GFR decline was attenuated by 45% in the xenon-group (10.9 ml min-1 1.73 cm-2 versus 19.7 ml min-1 1.73 cm-2 in the isoflurane group, but without significance (P = 0.084. Occurrence of adverse events was reduced (P = 0.003 in the xenon group. Renal function was similar among the groups after 3-6 months.Xenon anesthesia was feasible and safe in patients undergoing partial nephrectomy with regard to postoperative renal function. We found no significant effect on early renal function but less adverse events in the xenon group. Larger randomized controlled studies in more heterogeneous collectives are required, to confirm or refute the possible clinical benefit on renal function by xenon.ClinicalTrials.gov NCT01839084 and EudraCT 2012-005698-30.

    Primary progressive aphasia (PPA) is an untreatable neurodegenerative disorder that disrupts language functions. Previous studies have demonstrated transcranial direct current stimulation (tDCS) may improve language symptoms in patients with post stroke aphasia or neurodegenerative diseases. The present study investigated whether the application of anodal tDCS (AtDCS) to the scalp overlying the left dorsolateral prefrontal cortex (DLPFC), which may increase cortical excitability, in combination with individualized speech therapy would improve naming accuracy in the agrammatic variant of PPA (avPPA). Sixteen avPPA patients were randomly allocated into two subgroups: AtDCS (n = 8) or placebo tDCS (PtDCS). tDCS was applied over the left DLPFC (BA 8/9) 25 minutes per day for two weeks (10 days). Each patient underwent 25 minutes of individualized speech therapy with either AtDCS or PtDCS during each treatment session. Neuropsychological assessment, experimental naming, and linguistic abilities in daily living were assessed at baseline (T0), after two weeks of intervention (T1) and at a 12-week follow-up (T2). Significant improvement in experimental naming was observed in both groups at T1 and T2, but this effect was significantly greater in AtDCS than PtDCS patients. Naming correctness, as assessed using the Aachener Aphasie Test, increased selectively in the AtDCS group from T0 to T1, and this effect remained significant at T2. The analysis of daily living language abilities improved selectively in AtDCS group. Our results support the beneficial effect of targeted language training in combination with brain stimulation in avPPA patients. tDCS should be considered a useful tool for the improvement of language functions in patients with neurodegenerative diseases in future trials.

    Lesions in the ventrolateral region of the dominant frontal lobe have been historically associated with aphasia. Recent imaging results suggest that frontal language regions extend beyond classically defined Broca's area to include the ventral precentral gyrus (VPCG) and the arcuate fasciculus (AF). Frontal gliomas offer a unique opportunity to identify structures that are essential for speech production. The aim of this prospective study was to investigate the correlation between language deficits and lesion location in patients with gliomas. Nineteen patients with glioma and 10 healthy subjects were evaluated with diffusion tensor imaging magnetic resonance (MR) tractography, functional MR (verb generation task) and the Aachener Aphasie Test. Patients were divided into two groups according to lesion location with respect to the ventral precentral sulcus: (i) anterior (n=8) with glioma growing in the inferior frontal gyrus (IFG) and underlying white matter; (ii) posterior (n=11) with glioma growing in the VPCG and underlying white matter. Virtual dissection of the AF, frontal intralobar tract, uncinate fasciculus (UF) and inferior frontal occipital fasciculus (IFOF) was performed with a deterministic approach. Seven posterior patients showed aphasia classified as conduction (4), Broca (1), transcortical motor (1) and an isolated deficit of semantic fluency; one anterior patient had transcortical mixed aphasia. All posterior patients had invasion of the VPCG, however only patients with aphasia had also lesion extension to the AF as demonstrated by tractography dissections. All patients with language deficits had high grade glioma. Groups did not differ regarding tumour volume. A functional pars opercularis was identified with functional MR imaging (fMRI) in 17 patients. Gliomas growing in the left VPCG are much more likely to cause speech deficits than gliomas infiltrating the IFG, including Broca's area. Lesion extension to the AF connecting frontal to parietal

    In the very rare, cases where private clothing of persons working in a nuclear installation are inadvertently contaminated and this contamination is not detected when leaving the facility, there may be radiological consequences for this person as well as for members of his or her family. The VGB (Technische Vereinigung der Grosskraftwerksbetreiber) in Germany has investigated in detail the spread of contamination in nuclear power plants. Part of this evaluation programme was a radiological analysis which has been carried out by Brenk Systemplanung GmbH (Aachen/Germany). The radiological analysis started with the definition of the source term. It is highly unlikely that activities of more than 5 kBq 60 Co could leave a plant undetected on the body or the clothes. Nevertheless activities up to 50 kBq and different nuclide vectors were regarded. It has been found that 60 Co is the most important contaminant. The radiological analysis focusses on two types of contamination: particles and surface contamination. The pathways by which such a contamination can lead to an exposure by external irradiation or by ingestion depend on the type of contamination and are analysed in detail. For example, a particle could be retained in pockets or other parts of clothing and may lead to prolonged external irradiation until the piece of clothing is washed. The analysis is performed on the basis of conservative to realistic assumptions. In conclusion, the analysis has shown that especially particle contamination needs to be focussed on. However, by the advanced detection equipment in German plants doses which may pose a health hazard can safely be excluded. (authors)

    Light Emitting Diodes (LED) conquer the growing global market of lighting technologies. Due to their advantages, they are increasingly used in consumer products, in lighting applications in the home and in the mobility sector as well as in industrial applications. Particularly, with regard to the increasing use of high-power LED (HP-LED) the materials in the surrounding area of the light emitting semiconductor chip are of utmost importance. While the materials behind the semiconductor chip are optimized for maximum heat dissipation, the materials currently used for the encapsulation of the semiconductor chip (primary optics) and the secondary optics encounter their limits due to the high temperatures. In addition certain amounts of blue UV radiation degrade the currently used materials such as epoxy resins or polyurethanes for primary optics. In the context of an ongoing joint research project with various partners from the industry, an innovative manufacturing method for high precision optics for LED applications made of liquid silicone rubber (LSR) is analyzed at the Institut of Plastics Processing (IKV), Aachen. The aim of this project is to utilize the material-specific advantages of high transparent LSR, especially the excellent high temperature resistance and the great freedom in design. Therefore, a high integrated injection molding process is developed. For the production of combined LED primary and secondary optics a LED board is placed in an injection mold and overmolded with LSR. Due to the integrated process and the reduction of subcomponents like the secondary optics the economics of the production process can be improved significantly. Furthermore combined LED optics offer an improved effectiveness, because there are no losses of the light power at the transition of the primary and secondary optics.

Davis Jewish General Hospital, Montréal, Canada; 2Global Drug Safety, Grünenthal GmbH, Aachen, Germany; 3Johnson & Johnson Pharmaceutical Research and Development, L.L.C., Raritan, New Jersey, USAAbstract: The undertreatment of acute pain is common in many health care settings. Insufficient management of acute pain may lead to poor patient outcomes and potentially life-threatening complications. Opioids provide relief of moderate to severe acute pain; however, therapy with pure µ-opioid agonists is often limited by the prevalence of side effects, particularly opioid-induced nausea and vomiting. Tapentadol is a novel, centrally acting analgesic with 2 mechanisms of action, µ-opioid receptor agonism and norepinephrine reuptake inhibition. The analgesic effects of tapentadol are independent of metabolic activation and tapentadol has no active metabolites; therefore, in theory, tapentadol may be associated with a low potential for interindividual efficacy variations and drug–drug interactions. Previous phase 3 trials in patients with various types of moderate to severe acute pain have shown that tapentadol immediate release (IR; 50 to 100 mg every 4 to 6 hours provides analgesia comparable to that provided by the pure µ-opioid agonist comparator, oxycodone HCl IR (10 or 15 mg every 4 to 6 hours, with a lower incidence of nausea, vomiting, and constipation. Findings suggest tapentadol may represent an improved treatment option for acute pain.Keywords: tapentadol IR, acute pain, opioid, gastrointestinal tolerability

    The Mineral Vein Dynamics Modeling group ''FRACS'' started out as a team of 7 research groups in its first phase and continued with a team of 5 research groups at the Universities of Aachen, Tuebingen, Karlsruhe, Mainz and Glasgow during its second phase ''FRACS 11''. The aim of the group was to develop an advanced understanding of the interplay between fracturing, fluid flow and fracture healing with a special emphasis on the comparison of field data and numerical models. Field areas comprised the Oman mountains in Oman (which where already studied in detail in the first phase), a siliciclastic sequence in the Internal Ligurian Units in Italy (closed to Sestri Levante) and cores of Zechstein carbonates from a Lean Gas reservoir in Northern Germany. Numerical models of fracturing, sealing and interaction with fluid that were developed in phase I where expanded in phase 11. They were used to model small scale fracture healing by crystal growth and the resulting influence on flow, medium scale fracture healing and its influence on successive fracturing and healing, as well as large scale dynamic fluid flow through opening and closing fractures and channels as a function of fluid overpressure. The numerical models were compared with structures in the field and we were able to identify first proxies for mechanical vein-hostrock properties and fluid overpressures versus tectonic stresses. Finally we propose a new classification of stylolites based on numerical models and observations in the Zechstein cores and continued to develop a new stress inversion tool to use stylolites to estimate depth of their formation.

  12. Garzweiler II opencast mine - balance of interests between ecology and economy

    In the region including the three cities of Cologne, Aachen and Moenchengladbach the brown coal reserves amount to 55 Gt, of which about 7 Gt are located in the areas Bergheim, Inden, Hambach and Garzweiler in licensed opencast mines or in planned field extensions, with an overburden-to-coal ratio of less than 5.6:1. Favourable preconditions for profitable winning of the brown coal are created by the deposit conditions. At present, the yearly output lies between 105 and 110 Mt, of which about 85% are used to generate electricity, whilst 15% are supplied to the thermal energy market. In order to maintain the same coal output as hitherto, it is absolutely essential that winning should continue in the noth of the Rhineland mining area, that is in the Garzweiler II opencast mine extension. After extensive preliminary exploration the licensing procedure for this opencast mine commenced in 1987. Assuming that the procedure continues smoothly, it is anticipated that the crown coal development plan will be approved by the spring of 1995. With a project such as that of the Garzweiler II opencast mine different interests are involved. On the one hand, interest is focussed on a reliable and cheap supply of energy, on economically successful brown coal mining and on job security in the future. On the other hand, the planned opencast mine constitutes an encroachment of limited duration on a specific living space, economic region and natural environment. From the example of Garzweiler II it is clearly evident that the brown coal mining industry by adopting entirely new and highly efficient engineering techniques is making a significant contribution towards establishing a balance of interests.

    Reporting randomised controlled trials is a key element in order to disseminate research findings. The CONSORT statement was introduced to improve the reporting quality. We assessed the adherence to the CONSORT statement of randomised controlled trials published 2011 in the top ten ranked journals of critical care medicine (ISI Web of Knowledge 2011, Thomson Reuters, London UK). Design. We performed a retrospective cross sectional data analysis. Setting. This study was executed at the University Hospital of RWTH, Aachen. Participants. We selected the following top ten listed journals according to ISI Web of Knowledge (Thomson Reuters, London, UK) critical care medicine ranking in the year 2011: American Journal of Respiratory and Critical Care Medicine, Critical Care Medicine, Intensive Care Medicine, CHEST, Critical Care, Journal of Neurotrauma, Resuscitation, Pediatric Critical Care Medicine, Shock and Minerva Anestesiologica. Main outcome measures. We screened the online table of contents of each included journal, to identify the randomised controlled trials. The adherence to the items of the CONSORT Checklist in each trial was evaluated. Additionally we correlated the citation frequency of the articles and the impact factor of the respective journal with the amount of reported items per trial. We analysed 119 randomised controlled trials and found, 15 years after the implementation of the CONSORT statement, that a median of 61,1% of the checklist-items were reported. Only 55.5% of the articles were identified as randomised trials in their titles. The citation frequency of the trials correlated significantly (rs = 0,433; pcritical care medicine remains poor and needs considerable improvement.

    Randomised controlled trials (RCTs) are the gold standard for measuring the efficacy of any medical intervention. The present study assesses the implementation of the CONSORT statement in the top 11 anaesthesiology journals in 2011. We designed this study in order to determine how well authors in the top 11 ranked anaesthesiology journals follow the CONSORT statement's criteria. A retrospective cross-sectional data analysis. The study was performed at the RWTH Aachen University Hospital. Journals included Pain, Anesthesiology, British Journal of Anaesthesia, Regional Anesthesia and Pain Medicine, European Journal of Pain, Anesthesia and Analgesia, Anaesthesia, Minerva Anestesiologica, Canadian Journal of Anesthesia, Journal of Neurosurgical Anesthesiology and the European Journal of Anaesthesiology. All articles in the online table of contents from the top 11 anaesthesiology journals according to the ISI Web of Knowledge were screened for RCTs published in 2011. The RCTs were assessed using the CONSORT checklist. We also analysed the correlation between the number of citations and the adherence to CONSORT items. We evaluated 319 RCTs and found that, more than ten years after the publication of the CONSORT statement, the RCTs satisfied a median of 60.0% of the CONSORT criteria. Only 72.1% of the articles presented clearly defined primary and secondary outcome parameters. The number of citations is only weakly associated with the fulfilment of the CONSORT statement (r = 0.023). Adherence to the CONSORT criteria remains low in top-ranked anaesthesiology journals. We found only a very weak correlation between the number of citations and fulfilment of the requirements of the CONSORT statement.

    Full Text Available If we make a brief scan of the field known as Medical Robotics, we find that in recent years there has been an impetuous development of applications involving medical robots. Obviously, the most spectacular are remote robotic surgery systems, which, for example, in U.S. have been used in more than 3.5-4 million interventions. The systems AESOP, da Vinci and ZEUS are currently run in minimally invasive robotic surgery. Encouraging results were obtained at MIT (USA using robots in physiotherapy. Pearl is a robot designed as personal assistant of older patients, affected by disabilities. The Universities of Pittsburgh and Carnegie Mellon successfully develop it. In Plymouth and Aachen, researchers are involved in the creation of intelligent wheelchairs. At the University of Karlsruhe, robotic systems applicable to neurosurgery are created. Thus, the MICRoN project aims to create a robot to manipulate micron-sized objects with nanometer precision, applications including intervention in the living biological cells. In several research centers one works on the improvement of neural interfaces, from which it is expected a new generation of prostheses, controlled through functional electrical stimulation. It is also projected that the microsystem technology (MST will have a major impact in medicine through the introduction of new diagnostic techniques, dosing, remote microsurgery and neural prostheses, all based on the concept of minimally invasive therapy, mentioned above. This is the approximate image of research in Medical Robotics and obviously of some related fields, whose dynamics has been impressive lately, a trend that is maintained and even has clear signs of amplification, and fully justifies this approach. In this context, we will present the main concepts and applications of medical robotics in order to achieve a more suggestive and convincing image of this area of great interest and perspective.

    Semiconductor detectors processed in Aachen using Si GaAs from different manufactures have been irradiated with neutrons (peak energy ∼ 1 MeV) up to 4.0·10 14 n/cm 2 and protons (energy 24 GeV) up to 8.2·10 13 p/cm 2 . All detectors work well after the exposure. The leakage current density at 200 V of detectors made of AXT material increases by a factor of four after the highest neutron fluence and a factor of three after the maximal proton fluence. For the FEW-LC material the leakage current decreases significantly after irradiation. No significant difference can be observed between biased and non-biased detectors during the exposure to neutrons. The equivalent noise charged (ENC) calculated from the noise density spectra agrees well with that extracted from the pedestal width for the different neutron and proton fluences. Before irradiation the charge signals for minimum ionizing particles (MIPs) increase with the peaking time in the range of 40 ns to 2 μs, while this dependence cannot be observed after the exposure to neutrons or protons. The reason for this behaviour is the different time structure of the charge signals before and after irradiation. For AXT material the charge signals for MIPs correspond to 7100 electrons after 4.0·10 14 n/cm 2 and of 4300 electrons after 8.2·10 13 p/cm 2 are obtained. For FEW-LC material the signals at 200 V are reduced from 15700 electrons before irradiation to 6000 electrons after 8.2·10 13 p/cm 2 for this peaking time

    The aim of this study was to investigate biological effects and potential health risks due to two different metal-inert-gas (MIG) welding fumes (MIG welding of aluminium and MIG soldering of zinc coated steel) in healthy humans. In a threefold cross-over design study 12 male subjects were exposed to three different exposure scenarios. Exposures were performed under controlled conditions in the Aachener Workplace Simulation Laboratory (AWSL). On three different days the subjects were either exposed to filtered ambient air, to welding fumes from MIG welding of aluminium, or to fumes from MIG soldering of zinc coated materials. Exposure was performed for 6 h and the average fume concentration was 2.5 mg m(-3). Before, directly after, 1 day after, and 7 days after exposure spirometric and impulse oscillometric measurements were performed, exhaled breath condensate (EBC) was collected and blood samples were taken and analyzed for inflammatory markers. During MIG welding of aluminium high ozone concentrations (up to 250 μg m(-3)) were observed, whereas ozone was negligible for MIG soldering. For MIG soldering, concentrations of high-sensitivity CRP (hsCRP) and factor VIII were significantly increased but remained mostly within the normal range. The concentration of neutrophils increased in tendency. For MIG welding of aluminium, the lung function showed significant decreases in Peak Expiratory Flow (PEF) and Mean Expiratory Flow at 75% vital capacity (MEF 75) 7 days after exposure. The concentration of ristocetin cofactor was increased. The observed increase of hsCRP during MIG-soldering can be understood as an indicator for asymptomatic systemic inflammation probably due to zinc (zinc concentration 1.5 mg m(-3)). The change in lung function observed after MIG welding of aluminium may be attributed to ozone inhalation, although the late response (7 days after exposure) is surprising.

    Several existing field studies evaluate aluminium welding works but no thoroughly controlled exposure scenario for welding fume has been described yet. This study provides information about the uptake and elimination of aluminium from welding fumes under controlled conditions. In the Aachen Workplace Simulation Laboratory, we are able to generate welding fumes of a defined particle mass concentration. We exposed 12, until then occupationally unexposed participants with aluminium-containing welding fumes of a metal inert gas (MIG) welding process of a total dust mass concentration of 2.5 mg/m(3) for 6 h. Room air filter samples were collected, and the aluminium concentration in air derived. Urine and plasma samples were collected directly before and after the 6-h lasting exposure, as well as after 1 and 7 days. Human biomonitoring methods were used to determine the aluminium content of the samples with high-resolution continuum source atomic absorption spectrometry. Urinary aluminium concentrations showed significant changes after exposure compared to preexposure levels (mean t(1) (0 h) 13.5 µg/L; mean t(2) (6 h) 23.5 µg/L). Plasma results showed the same pattern but pre-post comparison did not reach significance. We were able to detect a significant increase of the internal aluminium burden of a single MIG aluminium welding process in urine, while plasma failed significance. Biphasic elimination kinetic can be observed. The German BAT of 60 µg/g creatinine was not exceeded, and urinary aluminium returned nearly to baseline concentrations after 7 days.

    Prosthetic heart valves can be associated to mechanical loading of blood, potentially linked to complications (hemolysis and thrombogenicity) which can be clinically relevant. In order to test such devices in pulsatile mode, pulse duplicators (PDs) have been designed and built according to different concepts. This study was carried out to compare anemometric measurements made on the same prosthetic device, with two widely used PDs. The valve (a 27-mm bileaflet valve) was mounted in the aortic section of the PD. The Sheffield University PD and the RWTH Aachen PD were selected as physical models of the circulation. These two PDs differ mainly in the vertical vs horizontal realization, and in the ventricular section, which in the RWTH PD allows for storage of potential energy in the elastic walls of the ventricle. A glassblown aorta, realized according to the geometric data of the same anatomical district in healthy individuals, was positioned downstream of the valve, obtaining 1:1 geometric similarity conditions. A NaI-glycerol-water solution of suitable kinematic viscosity and, at the same time, the proper refractive index, was selected. The flow field downstream of the valve was measured by means of the stereo-PIV (Particle Image Velocimetry) technique, capable of providing the complete 3D velocity field as well as the entire Reynolds stress tensor. The measurements were carried out at the plane intersecting the valve axis. A three-jet profile was clearly found in the plane crossing the leaflets, with both PDs. The extent of the typical recirculation zone in the Valsalva sinus was much larger in the RWTH PD, on account of the different duration of the swirling motion in the ventricular chamber, caused by the elasticity of the ventricle and its geometry. The comparison of the hemodynamical behaviour of the same bileaflet valve tested in two PDs demonstrated the role of the mock loop in affecting the valve performance.

    If one has computed a stationary state of an evolution equation, a major question is if the state is stable, and many different techniques have been developed to discuss this important question. Together with H.-O. Kreiss the author completed a survey article on nonlinear stability for time dependent PDEs. They give an account of the Lyapunov technique and the resolvent technique to study stability questions. It has been known for some time that the strength of the resolvent technique is the control of the small-wave-number projection of the solution, whereas Lyapunov`s technique is good for high wave numbers. In ref. 6 they succeeded in combining the two techniques. Together with T. Hagstrom, the author has studied somewhat related questions for flows at low Mach number. They show all time existence of classical solutions when the initial data are almost incompressible. The result is stronger than Hoff`s in that they can allow for a ball of slightly compressible data with a radius independent of the Mach number M. In contrast, the radius of Hoff`s ball shrinks to zero as M approaches 0. Together with H.-J. Schroll, RWTH Aachen, the author worked on conservation laws with stiff source term. From a mathematical point of view, these are singular perturbation problems for which the reduced problem is singular. In ref. 2 they introduce the notion of stiff well-posedness, which--in the linear constant coefficient case--characterizes all hyperbolic systems with stiff source term 1/{epsilon} Bu whose solutions converge for {epsilon} approaches 0. There are many applications. A rather new field, which has received considerable attention in the physics community, is self-organized criticality. Bak gives a popular account. The aim is to study the self-organization of systems towards a critical state and to understand the scaling properties at criticality. Together with the students the author has analyzed a model and has performed numerical simulations.

    This retrospective multicenter registry evaluated the safety and feasibility of left ventricular (LV) support with the Impella 2.5 (Abiomed Europe GmbH, Aachen, Germany) during high-risk percutaneous coronary intervention (PCI). Patients with complex or high-risk coronary lesions, such as last remaining vessel or left main lesions, are increasingly being treated with PCI. Because periprocedural hemodynamic compromise and complications might occur rapidly, many of these high-risk procedures are being performed with mechanical cardiac assistance, particularly in patients with poor LV function. The Impella 2.5, a percutaneous implantable LV assist device, might be a superior alternative to the traditionally used intra-aortic balloon pump. The Europella registry included 144 consecutive patients who underwent a high-risk PCI. Safety and feasibility end points included incidence of 30-day adverse events and successful device function. Patients were older (62% >70 years of age), 54% had an LV ejection fraction < or = 30%, and the prevalence of comorbid conditions was high. Mean European System for Cardiac Operative Risk Evaluation score was 8.2 (SD 3.4), and 43% of the patients were refused for coronary artery bypass grafting. A PCI was considered high-risk due to left main disease, last remaining vessel disease, multivessel coronary artery disease, and low LV function in 53%, 17%, 81%, and 35% of the cases, respectively. Mortality at 30 days was 5.5%. Rates of myocardial infarction, stroke, bleeding requiring transfusion/surgery, and vascular complications at 30 days were 0%, 0.7%, 6.2%, and 4.0%, respectively. This large multicenter registry supports the safety, feasibility, and potential usefulness of hemodynamic support with Impella 2.5 in high-risk PCI.

    . Veel universiteiten en hogescholen zijn hun sociaal werk curriculum aan het internationaliseren. Sommige docenten zijn overtuigd van het belang van internationalisering, anderen zijn weer tamelijk sceptisch over de toegevoegde waarde van internationalisering voor een beroepscarrière in het sociaal werk. Het doel van deze studie is om bij te dragen aan de discussie over het belang van internationalisering. Omdat de keuze voor internationalisering een ideologisch karakter heeft, dienen de betrokkenen hun eigen ideologische motieven en ambities te expliciteren. Vertegenwoordigers van opleidingen sociaal werk vulden een vragenlijst in met betrekking tot het doel van internationalisering, de structuur van hun curriculum, studenten- en stafmobiliteit, beleid en de grote uitdagingen op dit terrein. Deze studie toont aan dat op alle universiteiten en hogescholen de internationale dimensie is opgenomen in hun curriculum. Veel docenten “geloven” dat internationalisering bijdraagt aan kwalitatief betere professionals op lokaal niveau. Daarentegen zijn de meeste respondenten ontevreden over hoe hun opleidingen de ambities met betrekking tot internationalisering realiseren. Dit heeft te maken met het gemis aan taalvaardigheden en faciliteiten. Het vermoeden bestaat echter dat deze onvrede vooral te maken heeft met het onderliggende debat over “universalism” en “indigenisation” in het sociaal werk.

    Full Text Available [english] Background: Multiple choice questions (MCQs are often used in exams of medical education and need careful quality management for example by the application of review committees. This study investigates whether groups communicating virtually by email are similar to face-to-face groups concerning their review process performance and whether a facilitator has positive effects.Methods: 16 small groups of students were examined, which had to evaluate and correct MCQs under four different conditions. In the second part of the investigation the changed questions were given to a new random sample for the judgement of the item quality.Results: There was no significant influence of the variables “form of review committee” and “facilitation”. However, face-to-face and virtual groups clearly differed in the required treatment times. The test condition “face to face without facilitation” was generally valued most positively concerning taking over responsibility, approach to work, sense of well-being, motivation and concentration on the task.Discussion: Face-to-face and virtual groups are equally effective in the review of MCQs but differ concerning their efficiency. The application of electronic review seems to be possible but is hardly recommendable because of the long process time and technical problems.[german] Einleitung: Multiple-Choice-Fragen (MCF werden in vielen Prüfungen der medizinischen Ausbildung verwendet und bedürfen aus diesem Grund einer sorgfältigen Qualitätssicherung, beispielsweise durch den Einsatz von Review-Komitees.

    Full Text Available Til tross for lærerutdanningers mangeårige arbeid med å finne innovative løsninger som skaper gode sammenhenger mellom campuskonteksten og skolekonteksten, etterlyser lærerstudentene fortsatt en bedre sammenheng i studiet. Det som kjennetegner metodene i mange lærerutdanninger er at de bygger på ideen om læring for praksis. Dette innebærer i stor grad forventninger om at studentene transformerer kunnskap fra campus til undervisning og refleksjon i skolen. Mye tyder på at lærerstudentene får lite hjelp i denne prosessen. Studier om koherens – eller sammenheng – i lærerutdanningen knyttes sjelden til at lærerutdanning kan innebære et læringsproblem. Hensikten med denne artikkelen er å undersøke de læringsutfordringer studenter har når kunnskap skal transformeres mellom de to kontekstene. Tanken er at en forståelse for lærerstudenters læring på denne måten kan bidra inn i arbeidet med å videreutvikle metoder i lærerutdanningen som kan lette transformeringsprosessene. Artikkelen er tematisk og drøftes i lys av sosiokulturelle perspektiver på læring og utvikling med vekt på begrepene “overføring” og “transformering”. Videre drøftes problemstillingen i lys av studier av lærerstudenters interaktive læringsprosesser. Nøkkelord: lærerutdanning, lærerstudenters læringsprosesser, transformering av læring.AbstractDespite innovative work on bridging the gap between campus activities and classroom activities, student teachers ask for more coherence in their education. What characterizes the different teacher education innovations is that they are mainly based on the idea that students construct knowledge for practice. In these scenarios, teacher education programmes rely on the students’ ability to transform knowledge from activities at campus into teaching and reflection in their practice schools. The student teachers seem to get little or no help in these transformational processes. When studying

SKRIVUT-prosjektet svarer på en nasjonal og internasjonal etterspørsel etter gode møte­plasser for samarbeidet i lærerutdanninga. Møteplassen er et diskusjonsforum i It’s learning knyttet til praksisopplæringa der andreårsstudentene daglig skriver og får respons av medstudenter, praksislærer og faglærere i norsk og i pedagogikk og elevkunnskap. Studien som presenteres i artikkelen, bygger på kvalitativ analyse av loggdiskusjoner og intervjuer fra prosjektets andre år. Studien viser en faglig orientering i studentenes loggskriving og at det er mulig å etablere en samspillsarena. Den skriftlige dialogen i det digitale rommet viste seg å være drivende både for teoristudier og utvikling av fagspråk. Samtidig løftes praksislærers lokale og erfaringsbaserte kunnskap fram og settes i dialog med den teoribaserte kunnskapen. I diskusjonen tolkes karakteristiske trekk ved dialogen i det triadiske refleksjonsfellesskapet i lys av tenkning om behovet for situasjonsavgrensende og situasjonsoverskridende prosesser i læringskontekster. Funnene diskuteres opp mot studier som peker på at lærerstudenter og lærere har et mangelfullt fagspråk og er lite orientert mot etablert kunnskap.Nøkkelord: lærerutdanning, lærerstudenter, det digitale rom, samspillsarena, fagspråkAbstractThe background for this article is an intervention project in teacher education for primary school.

Ferner wurden 5 automatische Konturierungsmethoden (AM) ebenfalls angewendet. Die Groesse der Volumina und die Konkordanzindizes innerhalb der Gruppen (pCI) und relativ zu den Experten (eCI) wurden berechnet. E (pCI = 0,67) und EP (pCI = 0,53) zeigten eine signifikant hoehere Uebereinstimmung innerhalb der Gruppen im Vergleich zu SFS (pCI = 0,43, p = 0,03 und p = 0,006). Relativ zu E zeigte EP (eCI = 0,55) eine bessere Uebereinstimmung verglichen mit SFS (eCI = 0,49) oder S (eCI = 0,47). Die Intermethodenvariabilitaet von AM (pCI = 0,44) war aehnlich der von SFS und S, zeigte aber eine geringere Uebereinstimmung mit E (eCI = 0,35). Die Ergebnisse legen nahe, dass interdisziplinaere Kooperation fuer konsistentes Konturieren vorteilhaft sein kann. Eine gemeinsame Konturierung durch einen Strahlentherapeuten und einen Nuklearmediziner zeigte einen beachtlichen Konsens und eine bessere Uebereinstimmung mit den Experten im Vergleich zu anderen Fachaerzten. Eine relevante Intermethodenvariabilitaet der automatischen Algorithmen verdeutlicht die Notwendigkeit weiterer Standardisierung und Optimierung auch auf diesem Gebiet. (orig.)

    Therapy guidelines recommend speech and language therapy (SLT) as the "gold standard" for aphasia treatment. Treatment intensity (i.e., ≥5 hours of SLT per week) is a key predictor of SLT outcome. The scientific evidence to support the efficacy of SLT is unsatisfactory to date given the lack of randomized controlled trials (RCT), particularly with respect to chronic aphasia (lasting for >6 months after initial stroke). This randomized waiting list-controlled multi-centre trial examines whether intensive integrative language therapy provided in routine in- and outpatient clinical settings is effective in improving everyday communication in chronic post-stroke aphasia. Participants are men and women aged 18 to 70 years, at least 6 months post an ischemic or haemorrhagic stroke resulting in persisting language impairment (i.e., chronic aphasia); 220 patients will be screened for participation, with the goal of including at least 126 patients during the 26-month recruitment period. Basic language production and comprehension abilities need to be preserved (as assessed by the Aachen Aphasia Test).Therapy consists of language-systematic and communicative-pragmatic exercises for at least 2 hours/day and at least 10 hours/week, plus at least 1 hour self-administered training per day, for at least three weeks. Contents of therapy are adapted to patients' individual impairment profiles.Prior to and immediately following the therapy/waiting period, patients' individual language abilities are assessed via primary and secondary outcome measures. The primary (blinded) outcome measure is the A-scale (informational content, or 'understandability', of the message) of the Amsterdam-Nijmegen Everyday Language Test (ANELT), a standardized measure of functional communication ability. Secondary (unblinded) outcome measures are language-systematic and communicative-pragmatic language screenings and questionnaires assessing life quality as viewed by the patient as well as a relative

    The First Ph.D. Student Workshop ''Nuclear Safety Research'' of the Helmholtz Association of National Research Centers (HGF)'' was jointly organized by the Research Center Karlsruhe GmbH and the Energie Baden-Wuerttemberg AG (EnBW) from Wednesday 9th to Friday 11th March 2005. The workshop was opened with welcome greetings by Dr. Peter Fritz, Forschungszentrum Karlsruhe. Subsequently Dr. Joachim U. Knebel explained the main goals and the content of the workshop. The young scientists reported in 28 high-level presentations about their research work which covered a wide spectrum from reactor safety, partitions and transmutation, and innovative reactor systems, to safety research for nuclear waste disposal. The junior researchs showed excellent professional competence and demonstrated presentation qualities at the highest level. The successful funding of two Virtual Institutes, namely: the ''Competence in Nuclear Technologies'' and ''Functional Characteristics of Aquatic Interfaces both co-ordinated by Forschungszentrum Karlsruhe'', by the President of the Helmholtz Association Prof. Walter Kroell was the motivation for the organization of this first Ph.D. Student Workshop. Thanks to these two Virtual Institutes, the Reseach Center Karlsruhe and Juelich together with several univer-sities i.e. RWTH Aachen, Heidelberg, Karlsruhe, Muenster, and Stuttgart, have successfully financed eight Ph.D. and two post-doctoral students. Moreover, young scientists of the European Institute for Transuranium Elements (ITU) and additional seven Ph.D. Students, who are sponsored by the German nuclear industry (Framatome ANP, RWE Power, EnBW) in the frame of the Alliance Competence in on Nuclear Technology, and who are trained at Forschungszentrum Karlsruhe, actively contributed to this workshop. The EnBW-Award was handed over by Dr. Hans-Josef Zimmer, member of the board of directors of the EnBW-Kraftwerksgesellschaft, to Mrs. Ayelet Walter from the University of Stuttgart for the best

    Full Text Available For the understanding of the impact of meteorological stressors on human perceptions of thermal comfort, it is essential to examine in detail the joint variability of atmospheric conditions and human perception. We designed an interdisciplinary experimental setup to generate data of both human-biometeorological and individual human perception at two different urban public places in the city of Aachen, Germany. Meteorological measurements at the human-biometeorological standard height of 1.1 m a.g.l. were taken during typical winter weather situations as well as extreme summer weather situations to analyze potentially seasonal effects. Pedestrians and tourists at the study site were selected as participants for face-to-face questionnaire-based interviews. We took measurements and held interviews between 10:00 h and 17:00 h (CEST/CET to record the daytime agreement/deviations at different inner urban measurement locations. Based on an overall physical approach of thermal load, UTCI (Universal Thermal Climate Index values are calculated. A maximum of +34.1 °C for summertime and a minimum of +2.6 °C for wintertime could be found. The meteorological parameters of air temperature (Ta$T_{a}$, mean radiant temperature (Tmrt$T_{\\text{mrt}}$ and vapor pressure (VP are compared with data perceived by the persons interviewed. In winter, Ta$T_{a }$ shows a significant relation to the overall weather perception (r=0.28$r = 0.28$; p<0.05$p<0.05$ while the overall comfort of the participants is significantly related to perceived solar heat (r=0.27$r = 0.27$; p<0.5$p<0.5$ as well as to perceived Ta$T_{a}$ (r=0.4$r = 0.4$; p<0.002$p<0.002$. Quite different resulting patterns occurred for the summer campaign. None of the physical variables significantly affected the weather perception. Only the perceived Ta$T_{a}$ revealed a significant relation to the overall weather perception (r=0.27$r=0.27$; p<0.002$p<0.002$.

    This thesis discusses the search for supersymmetry at the future Large Hadron Collider (LHC) and the ongoing construction of one of the four large LHC experiments, the Compact Muon Solenoid (CMS), and focuses on the detection of signals from the annihilation of supersymmetric dark matter in the spectra of cosmic rays. The final steps of assembly of 1061 silicon microstrip detector modules for the CMS tracker endcaps are performed at the 1. Physikalisches Institut B at the RWTH Aachen. A laser test facility for these modules was developed and is described in this thesis. In contrast to test procedures based only on the evaluation of pedestal and noise data, the test facility relies on the generation of signals in the silicon sensors by infrared laser illumination. The fully automatic test facility provides high throughput and easy operation for the series production of the modules. Its performance is validated by investigating a reference module with artificially prepared defects of three types: open wirebonds, short-circuited strips and pinholes. It is shown that all defects are clearly detected. In addition to defect detection, an indication for the type of defect is provided. In a further validation step, nine modules from a prototype series are investigated with the laser test facility. Confirming the earlier results on the reference module, defective strips are reliably identified. This thesis describes a novel approach of positron identification with the space-borne AMS-01 experiment, namely through the detection of bremsstrahlung conversion in a silicon microstrip detector. In order to obtain the highest positron selection efficiency possible, novel combinatorial track finding algorithms were developed, particularly optimized for the signature of converted bremsstrahlung. By applying restrictions on the invariant mass of particles the background to the positron sample is largely eliminated. The remaining background contamination is determined from large

    Imaging methods for early, accurate diagnosis and aftercare of malignant growths is currently one of the most important research topics. The objective of this thesis is to evaluate the diagnostic value of FDG-positron emission tomography by comparison with computed tomography for patients with squamous cell carcinoma, malignant melanoma or sarcoma at head and neck. Measurement criteria are sensitivity and specificity. A retrospective evaluation of 100 examinations on 85 patients of University clinic Aachen was performed. The examination reports were supported by reports from histology, positron emission tomography and computed tomography. In each case, the histological results were assumed to provide a reliable benchmark. Sensitivity and specificity for the primary tumour site, metastatic lymphatic nodes and defined anatomic structures were compared across all patients. Comparisons were also performed on sub groups separated by gender, cancer type and the time and frequency at which tumours arose. The statistic analysis was done with MedCalc. Results: The results for sensitivity and specificity of the primary tumour site were 86.42% and 42.86%, and 64.71% and 66.07%, for positron emission tomography and computed tomography respectively. The results for the lymphatic nodes were 51.52% and 92.86% and 64.71% and 66.07%. When the constituent anatomic structures were evaluated separately, the specificity was significantly higher. The separation by gender showed no difference. Because the classification by tumor type resulted in samples that were of varying size, a comparison was difficult. For the diagnosis of primary tumours, the examination with positron emission tomography was superior, whereas computed tomography proved more effective for the diagnosis of recurrent tumours. For the diagnosis of the main tumour site, both methods were shown to be equally suitable. For the assessment of lymphatic nodes, positron emission tomography was superior to computed tomography

    Right ventricular failure is often the final phase in acute and chronic respiratory failure. We combined right ventricular unloading with extracorporeal oxygenation in a new atrio-atrial extracorporeal membrane oxygenation (ECMO). Eleven sheep (65 kg) were cannulated by a 28-Fr inflow cannula to the right atrium and a 25-Fr outflow cannula through the lateral left atrial wall. Both were connected by a serial combination of a microaxial pump (Impella Elect(®), Abiomed Europe, Aachen, Germany) and a membrane oxygenator (Novalung(®)-iLA membrane oxygenator; Novalung GmbH, Hechingen, Germany). In four animals, three subsequent states were evaluated: normal circulation, apneic hypoxia and increased right atrial after load by pulmonary banding. We focused on haemodynamic stability and gas exchange. All animals reached the end of the study protocol. In the apnoea phase, the decrease in PaO2 (21.4 ± 3.6 mmHg) immediately recovered (179.1 ± 134.8 mmHg) on-device in continuous apnoea. Right heart failure by excessive after load decreased mean arterial pressure (59 ± 29 mmHg) and increased central venous pressure and systolic right ventricular pressure; PaO2 and SvO2 decreased significantly. On assist, mean arterial pressure (103 ± 29 mmHg), central venous pressure and right ventricular pressure normalized. The SvO2 increased to 89 ± 3% and PaO2 stabilized (129 ± 21 mmHg). We demonstrated the efficacy of a miniaturized atrio-atrial ECMO. Right ventricular unloading was achieved, and gas exchange was well taken over by the Novalung. This allows an effective short- to mid-term treatment of cardiopulmonary failure, successfully combining right ventricular and respiratory bridging. The parallel bypass of the right ventricle and lung circulation permits full unloading of both systems as well as gradual weaning. Further pathologies (e.g. ischaemic right heart failure and acute lung injury) will have to be evaluated.

    2016-04-01

    Virtual Microscopy has advanced in recent years to a powerful versatile tool in the life sciences with many applications in research and teaching. We present the first virtual microscopy platform especially designed for geoscience applications. It was developed in a collaboration between RWTH Aachen University and Fraunhofer FIT under consideration of the demands of modern petrography. The system consists of a fully automated polarisation microscope that can scan entire thin sections in very high resolution under various polarisation and illumination conditions to capture and digitise all information that could be extracted from the section with classical polarised microscopy. The data is processed to extract the polarisation behaviour of each pixel as continuous functions that are fitted for each pixel based on images taken under different polarisation angles. This information is stored in a newly developed format that allows fast access and offers a very good degree of compression. The datasets can be viewed with a virtual microscopy software (TileViewer) that is easy to operate and allows fluent zooming and browsing through the thin section as well as rotation of the polarisers and switching between illumination conditions. The viewer software is platform independent and requires no special hardware, rather it operates well on a standard laptop. Besides navigation and image adjustments the TileViewer Software offers the possibility to create annotations, visualise the data based on certain characteristics (for example extinction direction), and offers a basic module for image segmentation. For further analysis the data can be exported to Matlab, ArcGis or other image analysis environments. The information density of each dataset (including the extinction behaviour) and the high resolution over very large continuous areas allows for new methods of automated and semi-automated analysis that was not possible before with single image acquisition and analysis

    The uptake and elimination of metals from welding fumes is currently not fully understood. In the Aachen Workplace Simulation Laboratory (AWSL) it is possible to investigate the impact of welding fumes on human subjects under controlled exposure conditions. In this study, the uptake and elimination of chromium or chromium (VI) respectively as well as nickel was studied in subjects after exposure to the emissions of a manual metal arc welding process using low or high alloyed steel. In this present study 12 healthy male non-smokers, who never worked as welders before, were exposed for 6h to welding fumes of a manual metal arc welding process. In a three-fold crossover study design, subjects were exposed in randomized order to either clean air, emissions from welding low alloyed steel, and emissions from welding high alloyed steel. Particle mass concentration of the exposure aerosol was 2.5mg m(-3). The content of chromium and nickel in the air was determined by analysing air filter samples on a high emission scenario. Urine analysis for chromium and nickel was performed before and after exposure using methods of human biomonitoring. There were significantly elevated chromium levels after exposure to welding fumes from high alloyed steel compared to urinary chromium levels before exposure to high alloyed welding fumes, as well as compared to the other exposure scenarios. The mean values increased from 0.27 µg l(-1) to 18.62 µg l(-1). The results were in good agreement with already existing correlations between external and internal exposure (German exposure equivalent for carcinogenic working materials EKA). The variability of urinary chromium levels was high. For urinary nickel no significant changes could be detected at all. Six-hour exposure to 2.5mg m(-3) high alloyed manual metal arc welding fumes lead to elevated urinary chromium levels far higher (7.11-34.16 µg l(-1)) than the German biological exposure reference value (BAR) of 0.6 µg l(-1) directly after

Patients and methods: During a 3-month observation period, 45 physicians (mainly palliative care specialists documented dosage and tolerability of tapentadol PR, previous and concomitant analgesic treatment, pain intensity, pain-related restrictions of daily activities and quality of life, and general state of health of 123 patients with chronic cancer-related pain in the context of a prospective noninterventional study. Results: All patients (mean age 63.9±13.2 years, 93.5% in constant pain had received analgesic long-term treatment (42.3% strong opioids prior to the start of tapentadol PR treatment. During the observation period, tapentadol PR significantly reduced the average pain intensity by 2.4 points (from a mean 6.1±1.7 to 3.7±2.0, P<0.001; half of the patients (52% achieved a pain score ≤3 at the end of observation. At the same time, mental and emotional well-being, pain-related impairments of daily activities, sleep quality, and quality of life improved, while the overall intake of analgesic concomitant medication could be reduced. Improvements in general state of health were significant (P<0.001. Overall, tapentadol PR was well tolerated. Conclusion: Good pain control with tapentadol PR was accompanied by markedly reduced pain-related mental and physical burden and quality of life improved. Overall, the general state of health of these patients with chronic cancer-related pain improved significantly despite the underlying
