    In order to reduce the decline in savings obtained from commissioning, a low cost fault detection and diagnostic tool that can continuously monitor energy consumption of buildings is required. The Energy Systems Laboratory at the Texas A and M University has developed a prototype of such a tool, known as the Automated Building Commissioning Analysis Tool (ABCAT). This prototype has been applied to the Vertigo building at the Eindhoven University of Technology. [Dutch] Omdat het wenselijk is de achteruitgang en/of degradatie van de gerealiseerde besparingen tegen te gaan die bij commissioning zijn bereikt, is er behoefte aan een goedkope tool voor foutdetectie en diagnostiek, die continu de energieprestatie (Continuous Commissioning) van een gebouw in de gaten kan houden. Het Energy Systems Laboratory, verbonden aan de Texas A and M University in de USA, heeft een prototype van zo'n tool ontwikkeld: Automated Building Commissioning Analysis Tool (ABCAT). Dit prototype is toegepast op het Vertigo gebouw van de Technische Universiteit Eindhoven.

    The Eindhoven linac-race track microtron (RTM) combination has been designed to serve as injector for an electron storage ring. The linac is a 10 MeV travelling-wave linac (type M.E.L. SL75/10). In the RTM a 5 MeV standing-wave cavity, which is synchronized with the linac, accelerates the electron beam 13 times, such that the extraction energy is 75 MeV. The RTM end magnets are two-sector magnets tilted in their median planes, to provide strong focusing forces for optimal electron-optical properties. Closed-orbit conditions are fulfilled with the help of small correction dipoles located in the RTM drift space; the magnetic-field strengths of these correction dipoles are adjusted on the basis of beam-position measurements. Isochronous acceleration is accomplished by position- and phase-measurements. A low-cost elaborate diagnostic system will be used for efficient commissioning of the combination of the 10 MeV linac and the 10-75 MeV RTM. (orig.) 10 refs.

  12. [Psychogeriatric emergency admissions in the area Eindhoven and the Kempen].

    1992-02-01

    In the Netherlands a special arrangement between the Regional Institute for Outpatient Mental Health Care (RIAGG) and nursing homes exists in region Eindhoven to deal with emergency admissions of psychogeriatric patients. Such an arrangement is necessary, because of long waiting lists for psychogeriatric nursing homes. This article describes the circumstances of 47 patients, who were admitted by this special arrangement. The group which had not been known before the crisis by RIAGG or nursing home (n = 21) is compared to those who had already been waiting some time for admission (n = 26). It appears that in the latter group the burden on the care taker becomes too heavy due to behavioural disturbances of the patient, while in the first group the coping abilities of the system decline due to acute illness or death of the care taker.

  13. Continuous Electron--Energy Variation of the Eindhoven Racetrack Microtron.

    1997-05-01

    Energy variation of the Eindhoven racetrack microtron, which has been designed as a fixed--energy electron accelerator at 75 MeV, is considered in this paper. By taking the orbit pattern in the RTM as constant and varying certain parameters continuous energy variation can be obtained. The microtron injector is a linac producing electrons between 6 and 12 MeV. The microtron cavity potential and the magnetic guide fields must be adapted to the injection energy in order to fulfil the synchronism condition. The transverse and longitudinal acceptance of the RTM are effected by deviations of the electron velocity from the speed of light, which are different for each parameter setting. An account of these effects is presented together with the energy--setting measurements by using one of the microtron magnets as a spectrometer.

    Plasma histidine-rich glycoprotein (HRG) was found to be persistently increased in a patient with a history of recurrent arterial thromboembolic events. The mean concentration was 270% of normal pooled plasma. Increased HRG was found in eight of the 17 relatives studied, but none of them has experienced thrombo-embolism yet. Apparently, increased HRG was hereditary with autosomal dominant inheritance. A significant correlation was found between the increased plasma concentration of the protein and the age of the subjects (P Eindhoven.

    The aim of this study was to estimate the prevalence of osteopenia and osteoporosis in perimenopausal women, and to assess determinants of low bone mineral density (BMD). All women born between 1941 and 1947 (aged between 46 and 54 years) living in the city of Eindhoven were invited to participate in the study: 5896 white Dutch women, representing 73% of the total number of Dutch women in this age group, were studied. Of these, 24% were using estrogen preparations and 19% had undergone hysterectomy, with or without oophorectomy. All women were interviewed and bone mineral density (BMD) of the lumbar spine was measured by dual-energy X-ray absorptiometry (DXA). Osteopenia and osteoporosis were defined according to the criteria proposed by a WHO working group. In the population studied the prevalence of osteopenia and osteoporosis was 27.3% and 4.1%, respectively. With progression from premenopause to menopause, the prevalence of osteoporosis increased from 0.4% to 12.7%, and that of osteopenia from 14.5% to 42.8%. An increased risk for low BMD (osteopenia and osteoporosis) was associated with age, menopausal status and smoking, while alcohol consumption, high body mass index (BMI) and use of estrogens had a protective effect. This study of a large population-based cohort of perimenopausal women revealed a high prevalence of low bone mass and, therefore, a higher risk for osteoporotic fractures. The data further suggest that, when issues on the long-term efficacy and safety of preventive treatments are resolved, it may be possible to identify women at higher risk who are most likely to benefit from screening strategies.

    The prevalence of co-morbidity among elderly lymphoma patients is associated with a decrease in the use of chemotherapy. This study assessed the independent prognostic effect of co-morbidity in 1551 unselected lymphoma patients, diagnosed between 1995 and 2001 in the area of the population-based Eindhoven Cancer Registry. The prevalence of serious co-morbidity was 58% for patients with Hodgkin's disease (HD) who were over 60 years of age and 66% for patients with non-Hodgkin's lymphoma (NHL) who were over 60 years of age. The administration of chemotherapy declined in the presence of co-morbidity for elderly patients with early-stage HD and elderly patients with aggressive NHL. Co-morbidity was associated with a 10-20% decline in 5-year survival. Whether less frequent application of chemotherapy in the presence of co-morbidity is justified as far as complications, prognosis and quality of life are concerned requires further investigation.

    In May 1989 an open access endoscopy service for general practitioners (GPs) was started in the region of Eindhoven. In the four hospitals covering a population of 500,000 inhabitants, served by 200 GPs, uniform working agreements were made. We evaluated the endoscopies performed in 1990 and compared the total number of endoscopies with that of gastrointestinal X-rays. A total of 996 open access gastroscopies were performed. The most important diagnoses were: peptic ulcer (19%), oesophagitis (16%), bulbitis (9%) and carcinoma (1.5%). The diagnostic yield was 57%. A total of 509 GP-referred sigmoidoscopies were performed. The most important diagnoses were: haemorrhoids and anal fissure (28%), colitis (15%), diverticulosis (12%), neoplastic polyps (11%) and carcinoma (4%). The diagnostic yield was 77%. Compared with 1989 the total number of gastroscopies, requested by GPs and by specialists, increased by 15% of which two-thirds were requested by the GPs. In this period the reduction of barium meals was 11% which was almost exclusively due to the specialist group. Sigmoidoscopies increased by 7%, entirely due to the GP group. The number of barium enemas remained constant. Open access endoscopy resulted in an increase endoscopies with only a partial substitution of radiological examinations. The increase in endoscopic examinations in the GP group did not result in a decline in the specialist group. The total diagnostic yield was 64%.

    1982-04-01

    In the region Eindhoven 36 children with Campylobacter-enteritis were examined from I January 1980 to 31 December 1980. Symptoms were studied and stools were cultured over a four-month period. Abdominal pain and/or diarrhea occurred in more than 90% of patients and were not infrequently of longer duration. Bloody stools were found in 58% of patients and disappeared relatively early during the time of illness, as well as fever and vomiting. After one month Campylobacter could only be cultured in 5% of children; 14 household contacts, who proved to have Campylobacter-enteritis, had also negative stool cultures after one month. Asymptomatic carriership was found in four cases among these household contracts. Campylobacter fetus subspecies jejuni could not be isolated in stools of a number of asymptomatic individuals, working in the meat industry, who were considered to have a higher risk of infection. This group could therefore not be determined as an endogenous human reservoir. On the other hand Campylobacter was isolated in a few domestic animals without symptoms of illness, as well as in some cattle stables and sites. In these places, where several contaminated animals are together, significant reservoirs for human infection may be present.

    2016-01-01

    At wastewater treatment plants (WWTPs), the aerobic conversion processes in the bioreactor are driven by the presence of dissolved oxygen (DO). Within these conversion processes, the oxygen transfer is a rate limiting step as well as being the largest energy consumer. Despite this high importance, WWTP models often lack detail on the aeration part. An extensive measurement campaign with off-gas tests was performed at the WWTP of Eindhoven to provide more information on the performance and behaviour of the aeration system. A high spatial and temporal variability in the oxygen transfer efficiency was observed. Applying this gathered system knowledge in the aeration model resulted in an improved prediction of the DO concentrations. Moreover, an important consequence of this was that ammonium predictions could be improved by resetting the ammonium half-saturation index for autotrophs to its default value. This again proves the importance of balancing sub-models with respect to the need for model calibration as well as model predictive power.

    Four experimental nursing home settings have been established by nursing home 'De Landrijt' in Eindhoven, each providing care for 4 or 5 long-stay psychogeriatric patients, in order to create flexible living conditions. Nurses are in overall charge; medical care is not provided on a daily basis, but only when necessary. Daily care is also suited to individual needs and possibilities of the patients. In order to evaluate these innovative nursing home conditions, 41 patients were compared with the same type of patients in conventional long-stay wards. To ensure that during the period of the evaluation the homes received the same types of patients, patients considered to need long-term nursing care were allocated randomly to the experimental and conventional homes. The development in functioning of the two groups was measured with a behaviour observation scale for elderly, the OPG--Observation Psychogeriatrics. The most important improvements for the experimental group are observed with respect to Orientation, Mood and Behavioural Problems, Instrumental Activities of Daily Living and Care provided to other patients. More physical aspects of impairment (for instance Activities of Daily Living, Incontinence and Contact) showed hardly any differences between the two groups. Other findings about the project (financial consequences, transfer to general health care) are briefly discussed.

  17. Fostering Sustainable Energy Entrepreneurship among Students: The Business Oriented Technological System Analysis (BOTSA Program at Eindhoven University of Technology

    Full Text Available The Business Oriented Technological System Analysis (BOTSA program is a new teaching and learning concept developed by Eindhoven University of Technology (the Netherlands with participation from innovative companies in renewable energy. It is designed to stimulate sustainable entrepreneurship among engineering students in this field. The program combines the placement of students in companies to study and contribute to the development and incubation of sustainable energy innovations, with a curriculum at the university designed to support these internships from a scientific perspective. The teaching method assists students in developing a broad system view that enables them to analyze the potential of, and bottlenecks to promising innovations from a realistic business perspective. This empowers students to identify those techno-economic aspects that are critical to innovation success, and advise the entrepreneurs about these aspects. Experience indicates that teachers, students, and entrepreneurs find BOTSA a valuable way of coaching, learning and working. Theoretical support for this method is found in system analysis originating in evolutionary innovation theory in combination with concepts of entrepreneurship, business model generation and sustainable/green innovation.

    Full Text Available Heute sind nicht nur diverse gestaltungsbezogene Disziplinen gefragt, sich aktiv mit der Digitalisierung von Information und ihren Potentialen und Nebenwirkungen für Bildungsprozesse auseinander zu setzen. In Deutschland haben sich Technikdidaktik und informatische Bildung getrennt von Medienpädagogik und Mediendidaktik entwickelt und wurden entsprechend unabhängig voneinander betrieben. Dies gilt auch für die Ästhetische Bildung, die informatisch-technische Inhalte kaum je curricular in die Auseinandersetzung mit digitaler Medienkultur integriert hat, schon gar nicht systematisch. Im diesem Artikel wird, ausgehend vom Stand der Forschung (zur Integration informatischer Inhalte in die Medienbildung und den identifizierten Grundproblemen der Medienbildung zwecks Kompensation der Defizite, ein auf Gestaltung basierter Ansatz präsentiert, kontextualisiert und diskutiert, der Technikverständnis in ein Konzept integrierter Medienbildung einbezieht, dies als Bildungsziel im Sinne eines ganzheitlichen Verständnisses von Welt begreift und daher disziplinüberschreitend angelegt ist. Der Ansatz geht über technokratische Vorstellungen einer Technikdidaktik hinaus, die Medientechnologien isoliert von lebensbedeutsamen, ästhetisch-künstlerisch gestalteten Kontexten betrachtet und vermittelt. Im didaktischen Konzept werden die Grundlagen informatischer Modellbildung als relevante Teilbereiche einer zeitgemässen, am Subjekt orientierten, gleichermassen ästhetisch-künstlerisch und technisch-informatisch geprägten Medienbildung aufgewiesen, ihre pädagogischen Vorläufer, Forschungsprojekte und Nachbardisziplinen benannt sowie Ausblicke für eine zeitgemässe Medienbildung gegeben.

    To determine risk factors for running injuries during the Lage Landen Marathon Eindhoven 2012. Prospective cohort study. Population-based study. This study included 943 runners. Running injuries after the Lage Landen Marathon. Sociodemographic and training-related factors as well as lifestyle factors were considered as potential risk factors and assessed in a questionnaire 1 month before the running event. The association between potential risk factors and injuries was determined, per running distance separately, using univariate and multivariate logistic regression analysis. In total, 154 respondents sustained a running injury. Among the marathon runners, in the univariate model, body mass index ≥ 26 kg/m(2), ≤ 5 years of running experience, and often performing interval training, were significantly associated with running injuries, whereas in the multivariate model only ≤ 5 years of running experience and not performing interval training on a regular basis were significantly associated with running injuries. Among marathon runners, no multivariate model could be created because of the low number of injuries and participants. This study indicates that interval training on a regular basis may be recommended to marathon runners to reduce the risk of injury.

    This paper illustrates how a dynamic model can be used to evaluate a plant upgrade on the basis of post-upgrade performance data. The case study is that of the Eindhoven wastewater treatment plant upgrade completed in 2006. As a first step, the design process based on a static model was thoroughly analyzed and the choices regarding variability and uncertainty (i.e. safety factors) were made explicit. This involved the interpretation of the design guidelines and other assumptions made by the engineers. As a second step, a (calibrated) dynamic model of the plant was set up, able to reproduce the anticipated variability (duration and frequency). The third step was to define probability density functions for the parameters assumed to be uncertain, and propagate that uncertainty with the dynamic model by means of Monte Carlo simulations. The last step was the statistical evaluation and interpretation of the simulation results. This work should be regarded as a 'learning exercise' increasing the understanding of how and to what extent variability and uncertainty are currently incorporated in design guidelines used in practice and how model-based post-project appraisals could be performed.

    Current diabetes education methods are costly, time-consuming, and do not actively engage the patient. Here, we describe the development and verification of the physiological model for healthy subjects that forms the basis of the Eindhoven Diabetes Education Simulator (E-DES). E-DES shall provide diabetes patients with an individualized virtual practice environment incorporating the main factors that influence glycemic control: food, exercise, and medication. The physiological model consists of 4 compartments for which the inflow and outflow of glucose and insulin are calculated using 6 nonlinear coupled differential equations and 14 parameters. These parameters are estimated on 12 sets of oral glucose tolerance test (OGTT) data (226 healthy subjects) obtained from literature. The resulting parameter set is verified on 8 separate literature OGTT data sets (229 subjects). The model is considered verified if 95% of the glucose data points lie within an acceptance range of ±20% of the corresponding model value. All glucose data points of the verification data sets lie within the predefined acceptance range. Physiological processes represented in the model include insulin resistance and β-cell function. Adjusting the corresponding parameters allows to describe heterogeneity in the data and shows the capabilities of this model for individualization. We have verified the physiological model of the E-DES for healthy subjects. Heterogeneity of the data has successfully been modeled by adjusting the 4 parameters describing insulin resistance and β-cell function. Our model will form the basis of a simulator providing individualized education on glucose control.

    HVAC installations, for example for office buildings, are in practice designed using computer simulations that rely on 40 year old weather data (1964-1965). This is already giving rise to comfort complaints in hot summer weather. A different approach to design is required if buildings are to continue performing well into the future. This problem was the subject of the graduation study reviewed in this article. [Dutch] Klimaatinstallaties in bijvoorbeeld kantoren worden in de praktijk ontworpen op basis van computersimulaties, waarbij gebruik wordt gemaakt van ruim 40 jaar oude weergegevens (1964-1965). In warme zomers zijn er nu al vaak comfortklachten. Om gebouwen te kunnen realiseren die ook in de toekomst goed blijven presteren is een andere benadering bij het ontwerpen nodig. Deze problematiek is het onderwerp geweest van een afstudeeronderzoek aan de Technische Universiteit Eindhoven, in samenwerking met Adviesburo Nieman en Vabi Software, dat in dit artikel wordt besproken.

    Full Text Available The question regarding, the nature o f a truly Christian University is addressed in this article. It is argued that such a university should develop a clear-cut concept of Christian scholarship (in the widest sense o f the term. Christian scholarship is not ‘derivect from the Bible or from any theology, hut founded in a radical Christian-philosophical view of reality and knowledge. A truly Christian university has the duly to work within and further develop such a Christian-cosmological and Christian-epistemological paradigm, and to point out and elaborate its relevance fo r the various sciences. If this is not done, scholars will, under the guise o f the Christian faith, unconsciously assume presuppositions of either a secular-humanistic, or a scholastic, or a biblicislic-fundamentalist nature. It is pointed out that the foundational questions concerning the various special sciences are necessarily of a philosophical nature, and that, if one wants to practise science on a Christian basis, one's philosophical paradigm has to be fully attuned to on e ’s Christian life and world view. For the time being, the author prefers the Reformational philosophy developed along the lines of Dooyeweerd, Vollenhoven, and Stoker, not because it is the best but because it is the only radical Christian, encompassing cosmology and epistemology available. The author makes this choice fully aware of the fact that this philosophy is, like all scientific theories, nothing but a fallible and preliminary construct, and that Christian scholarship vim not begun, or did not become possible, only with Dooyeweerd c.s.. The necessity of a radical Christian philosophy is based upon the presupposition that all human activity is founded in a ground-motif, and that the latter is necessarily of a religious nature.

    Full Text Available High-tech development—which lies at the very heart of the processes of economic growth—has been recognised by many developed and developing countries as a strategic instrument to enhance and sustain their competitiveness in the global economic network. Although the concept of high-tech development differs between countries, many share the underlying assumption that the core of high-tech development is to create a sound environment where innovation thrives. This ideology implies a definite spatial dimension. As a result, various spatial strategies have been formulated and implemented to support high-tech development. This has had intentional and unintentional effects on the economy, society and space.Numerous studies have been devoted to exploring, analysing and theorising this global phenomenon. However, there has been less attention given to the role spatial planning may play in the process of high-tech development and to the factors that shape the spatial planning approaches to high-tech development in a particular place. The major objectives of this research are to advance the knowledge of the role of spatial planning in the process of high-tech development, and to establish an analytical framework that helps reveal the major institutional factors that shape spatial planning mechanisms for dealing with the spatial issues of high-tech development in different places. This contributes to the field of high-tech spatial policies transfer and lesson-drawing.In order to explore the major factors that shape the practices of spatial planning in hightech development, a comparative approach is applied in this research. The Eindhoven city-region in the Netherlands and the Hsinchu city-region in Taiwan are selected as case study areas. Both city-regions can be recognised as success stories of high-tech development not only on a national scale but also on a global scale, despite the fact that they apply different approaches.

    With technical improvements in gradient hardware and the implementation of innovative k-space sampling techniques, such as parallel imaging, the feasibility of pulmonary perfusion MRI could be demonstrated in several studies. Dynamic contrast-enhanced 3D gradient echo sequences as used for time-resolved MR angiography have been established as the preferred pulse sequences for lung perfusion MRI. With these techniques perfusion of the entire lung can be visualized with a sufficiently high temporal and spatial resolution. In several trials in patients with acute pulmonary embolism, pulmonary hypertension and airway diseases, the clinical benefit and good correlation with perfusion scintigraphy have been demonstrated. The following review article describes the technical prerequisites, current post-processing techniques and the clinical indications for MR pulmonary perfusion imaging using MRI. (orig.) [German] Mit der Verfuegbarkeit leistungsfaehiger Gradientensysteme und schneller k-Raum-Akquisitionstechniken wie der parallelen Bildgebung konnten verschiedene Studien die Machbarkeit der Lungenperfusionsbildgebung in der MRT zeigen.

    Due to the current liberalization process the European gas business is changing rapidly. Many new problems that arise will have to be solved by practical solutions. Especially the German gas business with its very heterogeneous structure is already facing a lot of difficulties, which may also become apparent on a European level with further liberalization progress. An example is the handling of transportation for household customers on the basis of load profiles. The second amendment of the German gas association agreement encompasses technical guidelines for network access, which encompass solutions for some of the arising problems. It becomes evident that the technical guidelines are equivalent to a functional standard for third party access in the German gas market. (orig.) [German] Die europaeische Gaswirtschaft befindet sich, verursacht durch die Liberalisierung der Energiemaerkte, in einer rasanten Umbruchphase.

    Evidence for an anomalous annual periodicity in certain nuclear decay data has led to speculation concerning a possible solar influence on nuclear processes. We have recently analyzed data concerning the decay rates of Cl-36 and Si-32, acquired at the Brookhaven National Laboratory (BNL), to search for evidence that might be indicative of a process involving solar rotation. Smoothing of the power spectrum by weighted-running-mean analysis leads to a significant peak at frequency 11.18/yr, which is lower than the equatorial synodic rotation rates of the convection and radiative zones. This article concerns measurements of the decay rates of Ra-226 acquired at the Physikalisch-Technische Bundesanstalt (PTB) in Germany. We find that a similar (but not identical) analysis yields a significant peak in the PTB dataset at frequency 11.21/yr, and a peak in the BNL dataset at 11.25/yr. The change in the BNL result is not significant since the uncertainties in the BNL and PTB analyses are estimated to be 0.13/yr and 0....

    This article proposes a lexicographical approach to the compilation of multilingual concept literacy glossaries which may play a very important role in supporting students at institutions of higher education. In order to support concept literacy, especially for students for whom English is not the native language, a number of universities in South Africa are compiling multilingual glossaries through which the use of languages other than English may be employed as auxiliary media. Terminologies in languages other than English are developed by translating English terms or coining new terms in these languages to exploit the native language competence of most students. The glossary project at the University of Cape Town (UCT which was conceived under the auspices of the Multilingualism Education Project (MEP is discussed. It is shown that the UCT glossaries are compiled using methods consistent with those employed in modern lexicography or proffered in lexicographical theory. The lexicographical function theory is specifically used to account for the glossaries and their production. It is suggested that modern lexicography can provide useful guidance for the production of glossaries, given that the earliest glossaries constitute the humble beginnings of lexicography.

    Optimisation and development of technical combustion systems in order to generate energy efficiently and reduce pollution is an ever-increasing challenge. Mathematical and numerical simulations play a very important role in this context. This project was dedicated to the implementation and improvement of mathematical models and subsequent verification of the modelling concepts. Verification used data measured by the university department for combined cyle turbines. The focal point of interest was the reaction zone near the burner. Further points of interest: development and improvement of models for two-phase effects, fuel consumption and turbulence interaction as well as further development of the methods of numerical simulation. Simulating the combustion chamber of the combined cycle turbines was prioritised.(orig.) [German] Die Optimierung und Weiterentwicklung technischer Verbrennungssysteme mit dem Ziel einer moeglichst effizienten und schadstoffarmen Energiebereitstellung stellt eine staendig wachsende Herausforderung dar. Bei der technologischen Umsetzung dieses Ziels kommt der mathematisch-numerischen Simulation eine immer groessere Bedeutung zu. In diesem Projekt sollte die Implementierung und Verbesserung von mathematischen Modellierungsansaetzen sowie die anschliessende Verifikation der Modellierungskonzepte anhand der Messdaten des Lehrstuhls fuer Dampf- und Gasturbinen (LDuG) durchgefuehrt werden. Der Schwerpunkt lag in der brennernahen Reaktionszone. Konkrete Arbeitsschwerpunkte waren die Weiterentwicklung und Verbesserung der Modellansaetze fuer Zweiphaseneffekte, Brennstoffumsatz und Turbulenzinteraktion sowie die Weiterentwicklung der Methodik der numerischen Simulation. Dabei stand die Simulation der Brennkammer des LDuG im Vordergrund. (orig.)

    New deformable mirror technology is developed by the Technische Universiteit Eindhoven, Delft University of Technology and TNO Science and Industry. Several prototype adaptive deformable mirrors are realized mirrors, up to 427 actuators and ∅150mm diameter, with characteristics suitable for future AO systems. The prototypes consist of a 100µm thick, continuous facesheet on which low voltage, electromagnetic, push-pull actuators impose out-of-plane displacements. The variable reluctance actuators with ±10µm stroke and nanometer resolution are located in a standard actuator module. Each module with 61 actuators connects to a single PCB with dedicated, 16 bit, PWM based, drivers. A LVDS multi-drop cable connects up to 32 actuator modules. With the actuator module, accompanying PCB and multi-drop system the deformable mirror technology is made modular in its mechanics and electronics. An Ethernet-LVDS bridge enables any commercial PC to control the mirror using the UDP standard. Latest results of the deformable mirror technology development are presented.

    The indoor climate of a recently renovated Dutch museum falls short of the criteria stipulated in the specifications and of guidelines for collection conservation, despite the presence of an HVAC system. A measurement programme was installed in order to monitor the interior conditions over a lengthy period. The results reveal that the problems are primarily a result of malfunctioning of the HVAC system. The humidification capacity also appears to have been underestimated. Furthermore, the ventilation principle applied in the museum is inappropriate for creating stable, homogenous interior air conditions. [Dutch] Het binnenklimaat in een recent gerenoveerd Nederlands museum voldoet niet aan de in het bestek gestelde criteria en aan richtlijnen voor collectiebehoud, hoewel een klimaatinstallatie aanwezig is. De Technische Universiteit Eindhoven heeft een uitgebreid meetprogramma uitgevoerd om het klimaat in de tentoonstellingszalen langdurig te monitoren. Meetresultaten tonen aan dat de problemen vooral worden veroorzaakt door het disfunctioneren van de klimaatinstallatie. Daarnaast blijkt de bevochtigingscapaciteit krap bemeten. Uit literatuur en metingen blijkt dat het toegepaste ventilatieprincipe in de tentoonstellingszalen per definitie ongeschikt is om een stabiel en homogeen binnenklimaat te creeren.

    ook relatieve vochtigheid en CO2. Een 'representatieve' tuinder of een tuinder met een 'gemiddelde' energiebehoefte is daarom moeilijk vast te stellen. Voor elke situatie geldt een eigen economische rentabiliteit. De uitkomsten van deze studie kunnen daarom niet zonder meer worden overgenomen voor andere projecten. Technisch is er veel mogelijk, zo blijkt uit de ingediende offertes. Van de zestien leveranciers bieden er drie een vergasser met warmtekrachtkoppeling (WKK) aan die, onder bepaalde randvoorwaarden, naast hout tevens laagwaardige reststromen aankan. Het voordeel van laagwaardige reststromen zoals bermgras, riet en miscanthus is een gunstigere prijs ten opzichte van hout. Een lage biomassaprijs heeft een positief effect op de exploitatiekosten, en daarmee op de economische rentabiliteit van de relatief kostbare installaties. De investering voor een complete vergasserWKK-installatie ligt 5 tot 10 keer hoger dan die voor een gangbare gasWKK-installatie. Ook het CO2 -gebruik heeft invloed op de economische rentabiliteit. De inkoop van CO2 is een kostbare aangelegenheid. Onderzocht is of er zowel technisch als economisch beschikbare CO2 -winning uit rookgas mogelijk is. Hiervoor zijn twee CO2 -winninginstallaties bekeken: die van Procede en Knook. Voor een vergasser-WKK-installatie met relatief klein vermogen (tot 800 kWe) is CO2-winning volgens zowel Procede als Knook economisch niet rendabel. CO2 -inkoop of -opwekking middels de bestaande aardgasgestookte ketel ligt daarom meer voor de hand. Uit de technisch-economische haalbaarheidsstudie blijkt dat door de relatief hoge investerings- en onderhoudskosten, investeren in een vergasserWKK-installatie niet rendabel is. CO2 -behoefte en de onzekerheid van de biomassaprijzen spelen daarbij parten. Maar met subsidie op duurzame energieproductie (SDE+) en subsidies op investering zoals MEI en EIA ontstaat een ander beeld. Uitgaande van de goedkopere 800 kWe installaties, een SDE+ vergoeding van 90

    For years, the so-called new actuators, the ``muscles of microelectronics``, have been gaining in importance in all fields of technology. Actuators consist of functional elements, i.e. power amplifiers, energy transducer, and gearings. They convert electrical energy into mechanical energy and switch, control or regulate technical processes. The use of new or multifunctional materials such as piezoelectric low-voltage PZT ceramics and electrorheological and magnetorheological fluids (ERF and MRF) has added many new types to the existing conventional ones. Numerous improved and new microsystems, mechatronics and adaptronics products will depend on the performance, i.e. forces, travel, actuating time, energy density, and unit volumes, of new actuators. There will be an increasing demand for multifunctional properties such as simultaneous sensor and actuator operation. This manual gives a comprehensive survey of the state of the art, the state of science, and of developments. It discusses the design of new actuators, the corresponding production technologies, the performance of actuators, and future trends. 18 sections are dedicated to the mechanical design of actuators, to actuator travel modifications, electronic triggering, and to technology and market potentials. Selected practical examples reveal the great application and product potentials of new actuators and facilitate access to design solutions. (orig.). 309 figs., 35 tabs., 412 refs.

    Kossert and Nahle of the Physikalisch-Technische Bundesanstalt (PTB) have recently studied measurements from their beta-decay experiment that registers triple coincidences in a TDCR (Triple-to-Double Coincidence Ratio) system. Our analysis of the PTB data reveals evidence (which is a function of solar elevation) of an oscillation at 11 year-1, which we interpret as an influence of internal solar rotation. For comparison, we have analyzed radon beta-decay data for exactly the same time interval acquired at the Geological Survey of Israel (GSI). This analysis yields strong confirmation of the 11 year-1 rotational signal and of its dependence on solar elevation. These results are compatible with the proposition that beta decays may be stimulated by solar neutrinos.

    Within the framework of the project 'Fresh Schools' the NL Agency has set up a program of technical requirements for schools of primary and secondary education, where requirements for energy efficiency and indoor environment in the categories A (very good), B (good) en C (acceptable) were developed. In new construction projects basically the minimum performance requirements of category B is recommended. This article is based on a computational study at a primary school to see what the consequences are of this program of requirements (category B), with respect to the choice of the climate installation concept, the need for cooling, the energy performance and the necessary installation costs. [Dutch] Agentschap NL heeft in het kadervan het project 'Frisse Scholen' een technisch Programma van Eisen ontwikkeld voor scholen voor het basisonderwijs en het voortgezet onderwijs. Daarin zijn eisen uitgewerkt voor de energiezuinigheid en het binnenmilieu in de klassen A (zeer goed), B (goed) en C (acceptabel). Bij nieuwbouwprojecten gelden in principe minimaal de prestatie-eisen volgens klasse B. Een rekenstudie aan een basisschool laat zien wat de consequenties van dit Programma van Eisen (klasse B) zijn voor de keuze en het ontwerp van de klimaatinstallatie, de noodzaak van koeling, de energieprestatie en het benodigde budget voor de installaties.

    Full Text Available The fact that clinical evaluation is a difficult and complex task of nursing education has been emphasized in the nursing literature since the early seventies. It is, nevertheless, a most important component of the teaching-learning process of nursing students and it has definite advantages. It: * contributes to the improvement of the standard of nursing care * helps to identify problem areas for research and * contributes to high level professional preparation. In the light of these factors the aims of the study were to: * determine and describe the position of clinical evaluation as a component of the teaching of undergraduate students in departments of nursing at universities in Southern Africa; * draw up a proto-theoretical model for clinical evaluation. The second aim will be fully discussed in a follow-up article. The empirical data showed that nursing educationists in Southern Africa are not entirely up to standard regarding the skills required for clinical evaluation.

    On referral by ophthalmologists, the Visual Advice Centre provides the partially sighted with advice and prescriptions for illumination and visual aids. In this paper the multidisciplinary structure of the centre is presented and the results obtained in the first 18 months of its existence are discussed. Two hundred and ninety-eight patients were referred to the centre in this period. The majority of these patients (79.2%) were older than 60 years. The main cause of visual impairment was macular disease (45.3% of the patients). An interesting finding is that, although reading is an important need, reading problems only constituted 35.9% of the total number of demands for help. From an inquiry into the situation of 125 patients 6 months after prescription, it appears that more than 90% of the aids prescribed are used regularly. The conclusion is drawn that patients referred to the Visual Advice Centre benefit from the multi-disciplinary approach to their problems.

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

    ''PTB's central mission and the demands it places on itself are to make available an innovative metrological infrastructure at the highest international level in Germany to promote Germany's export-oriented high-tech economy, to meet the demands of a complex society and to support science that is operating at the cutting edge worldwide.'' This is what is stated in the ''Agreement on Objectives'' for the years from 2015 to 2019 between the Federal Ministry for Economic Affairs and Energy (Bundesministerium fuer Wirtschaft und Energie - BMWi) and PTB, which was signed on 12 January 2016 by State Secretary Machnig and me. Both this agreement and the newly developed ''Work and research program 2015 to 2017'' thus clearly define PTB's medium-term guidelines focusing on ''Innovation and industry'', ''Energy and the environment'', ''Humans and health'', ''Legal and international metrology'' as well as ''The new System of Units''.

    This publication of Institut fuer wirtschaftliche Oelheizung (IWO) is the first practically oriented and nationally valid publication with information on the construction of petroleum systems. It is addressed first of all to craftsmen in this field, who are given support in their everyday work. The book describes specifications for projecting and installation, from filler nozzles to exhaust line mouths, on the basis of which oil heating systems can be installed that meet all relevant criteria. It is the first comprehensive compendium containing the current technical rules reflecting the state of the art, as well as all relevant legal regulations and explanations and information for practical work. Specific legal regulations of individual German states, ordinances and directives for protection of water and for fire protection are included as well. This is especially useful for those craftsman's shops that work in different German states and must work in compliance with divergent regulations. Some of the most relevant legal regulations are also presented in excerpts for quick reference to the original text. (orig.)

    Full Text Available From metaphysics to hermeneutics: in this way one could describe the turn which took place in Western culture on account of the growth of modernity, ever since the Enlightenment. This philosophical expression also touches on religion, and especially theology. To use the words of the philosopher Gianni Vattimo (2006:49, we live in �het tijdperk van de interpretatie� (the age of interpretation. Against this background, it is not a strange thing that hermeneutical competence is generally judged to be the primary skill of the minister. In this article, I aim to set down my views on the far-reaching consequences which the choice of hermeneutical competence as primary skill entails. This I will do by way of the question: If one chooses theology and ministry, how does one become hermeneutically competent?

    Technische Universität Darmstadt is a famous German technical university whose graduates are preferred by German enterprises. Its training program was analyzed in this paper to show the positive alternate action of university and enterprise on the self-development of the students. Then three suggestions were made for the Chinese higher education of engineering. The first is to let the enterprises participate more in the higher educa-tion by making new rules;the second is to employ different levels of teachers who have more industrial experiences;the third is to avoid the habit that teachers are busy with students' duty and the students obey only.%德国达姆斯塔特工业大学是一所毕业生深受德国企业界欢迎的著名大学。文章通过分析其机械系的培养方案展示了大学与企业交替性发挥作用帮助学生通过自主性学习走向独立工作的过程,给正在改革的中国工程教育提出了几点改善学生自我塑造环境的建议:一是通过建立制度让企业更多地参与;二是聘用具有更多企业经历的、多层次的高校教师;三是要避免教师代替学生忙碌的现象。

    2014-03-01

    Full Text Available Astronomy after Oort: The Changes in Administrative Culture in Science and the Universities in the 1970s and 1980sIn the early 1970s Dutch universities were reformed, while scientific research was faced with new social and political demands. A decade later science and university policy changed again, with increasing roles for market pressure and competition.These developments might seem opposed, but in this paper David Baneke will argue that in fact there was great continuity, both concerning the backgrounds of the policy and the practical consequences. Their goal was to cope with the rapid increase in scale and the costs of science, to open up closed elitist networks, and to counter inefficiency and arbitrary spending. The pressure to reform came both from policy makers and from within the universities themselves. In all cases the changes resulted in professional management structures and an increase in bureaucracy.In this paper, Baneke will analyse these developments from theperspective of the internationally prominent Dutch astronomical community, which experienced a serious crisis in 1970 in which every part of the disciplinary infrastructure was reconsidered. Rond 1970 werden de Nederlandse universiteiten grondig hervormd en werden er nieuwe maatschappelijke eisen gesteld aan wetenschappelijk onderzoek. In de jaren tachtig werden die hervormingen deels teruggedraaid, terwijl marktwerking en concurrentie een grotere plaats kregen in het wetenschapsbeleid.Die ontwikkelingen lijken tegenstrijdig, maar in dit artikel betoogt David Baneke dat er een grote continuïteit bestaat, zowel in de achtergronden van het beleid als in de uitwerking in de wetenschappelijke praktijk. Het waren pogingen om schaalvergroting en kostenstijging beheersbaar te houden, gesloten regenteske netwerken open te breken en willekeur en inefficiëntie te bestrijden. De druk om te veranderen kwam zowel van de overheid als uit de universiteiten zelf. Het gevolg was in alle gevallen een sterke groei van professionele managementstructuren en bureaucratie. Baneke analyseert deze ontwikkelingen vanuit het perspectief van de internationaal prominente Nederlandse astronomische gemeenschap, die rond 1970 een ernstige crisis doormaakte waarin de hele disciplinaire structuur ter discussie stond.

    Full Text Available Pieter Dhondt, The lost campaign for one single university in Belgium, 1814-1835After the defeat of Napoleon and the disappearance of the existing institutions for higher education, the struggle for a university flared up between a number of Belgian cities. Countless pamphlets were published in quick succession; many defended the establishment of one single university, others argued that several institutions should be set up. All of them supported the idea of a university in their own city. Few people were satisfied with the autocratic decision of Wilhelm I in 1816 to establish three state universities. Towards the end of the 1820s the issue came up again. The establishment of free universities after the revolution added an ideological component to the debate. It was only in 1835 that an agreement was finally reached on the number of universities and their location. The compromise was far from clear and, as had been the case fifteen years earlier, those advocating the concentration of all intellectual and financial resources into one singleinstitution had lost their case.

    Full Text Available The medium of instruction at South African universities: The case of Afrikaans In this article the focus is on the diminished role of Afrikaans as medium of instruction at South African universities. The tendency world-wide is that governments regard universities as national assets and therefore continuously encroach on what is idealistically termed “academic freedom”. In South Africa the ideologically-driven government has targeted education as a strategic terrain and has published several white papers and promulgated as many labour laws with the stress on “redress”, “access”, “equal opportunities”, “recognition of prior learning” and a “uniform qualification system”. All these measures are aimed to create one uniform education system and the use of Afrikaans as medium of instruction is clearly seen as detrimental to this august ideal.

A Presbyterian minister, Prof E MacMillan, lectured from 1917 till 1934. This marked the end of Presbyterian participation. In the next period, 1935-1937, the Department suffered from a controversy between the Nederduitsch Hervormde Kerk and its new partner, the Nederduitsch Hervormde of Gereformeerde Kerk.

    Analysis of dust samples from uranium enrichment facilities is focused on the detection and analysis of uranium-containing particles. A chemical and isotopic analysis of individual particles from dust samples is thought to be an effective analytical tool to check the absence of nuclear-weapon production activities. The used different analytical techniques from individual laboratories have to be verified with respect to their uncertainties and limits of detection. This requires a well-characterized uranium micromass standard, composed of particles with a narrow spread in the uranium mass distribution. In this work the relative uranium mass distribution is determined of a set of U 3O 8 micro particles. The measured set of particles is monodisperse with a standard deviation of the relative uranium mass distribution of 16%.

    It is with pleasure and pride that we present the selected contributions from participants of the 11th High-Tech Plasma Processes conference. This conference, which took place in Brussels from June 28 to July 2 2010, is based on a European forum with a history of more than twenty years. The conference series started as a thermal plasma conference and gradually expanded to include other topics and fields as well. HTPP 11 was organized in collaboration with the Belgian Interuniversity Attraction Pole (IAP): Physical chemistry of Plasma-surface Interactions (PSI-ψ). The program was devised by the plasma group of the Technische Universiteit Eindhoven in collaboration with the IAP, the Association Arc Electrique and the International Scientific Committee. The organization was guided by the Steering Committee and supervised by the two founding members, Jacques Amouroux and Pierre Fauchais. HTPP aims to bring together different scientific communities to facilitate contacts between science, technology and industry, providing a platform for the exploration of elementary processes in and by plasmas. This implies that, apart from fundamental topics, considerable attention is paid to new plasma applications; plasma engineering in Europe is one of the main driving forces behind HTPP. The conference supports the dissemination of methods for plasma diagnostics and monitoring and the exchange of models for plasmas sources and plasma applications. A novelty of HTPP 11 was the model market; a special type of poster session where running models were demonstrated and spectators were challenged to assemble their own plasma models using one of the available construction platforms. For the first time in this series of conferences, the proceedings are published in two companion issues: Journal of Physics D: Applied Physics, which presents a selection of papers including invited and keynote papers, and the Journal of Physics: Conference Series. The present volume of the Journal of Physics

    Full Text Available The Faculty of Theology (Sec A at the University of Pretoria: Inquiry into its identity and problem areas This article is a short survey of theological viewpoints on the character and task of the church, as reflected in church literature during the past 75 years. It is shown that political history after World War II had a marked effect on thinking in the Nederduitsch Hervormde Kerk and that recent changes on the political scene pose penetrating questions to theologians. A full inquiry into the contours of self-definition is called for and some relevant issues are indicated; an honest evaluation in respect of the political and social context which is reflected in positions adopted, a pastoral compassion which takes note of human misery, cognisance of the ecumenical character of the church, and ethical and academic responsibility.

    Full Text Available Do values contain directional-normative value? A review of the value project of the North-West University As indicated in the title, the aim of this article is to determine the value (if any of values, especially as expressed by a valuedriven institution. To avoid abstract reflection, the article (cf. the subtitle focuses on a specific institution, viz. a university. To concretesise the investigation even more, the North-West University (which came into existence in 2004 is taken as a case study. The investigation develops as follows: by way of introduction, attention is first given to the popularity of present value thinking, followed by the problem statement: Are such values really capable of indicating a normative direction? Secondly, the development of a university with a normative foundation (the erstwhile Potchefstroom University for Christian Higher Education towards a value-driven one (the new North-West University is briefly described. In the third place a brief description of the NWU as a value-driven institution is given. Fourthly, attention is given to some practical problems which surfaced during the implementation of the value project. Fifthly, six theoretical-philosophical problems regarding the NWU’s value system are discussed. The next main point consists of a brief description from a reformational perspective (of structure, direction and relevance of what an academic institution ought to be. Apart from expressing doubt about the real value of values to give a solid foundation and clear direction to a university, the preliminary conclusion also suggests further philosophical reflection on the real nature, status and authority of values.

    Proton microprobe techniques are useful in investigating ischemia-reperfusion induced ion shifts between cardiac muscle cells and interstitial fluid. Preliminary results have shown that proper analysis of ion concentrations in various cardiac compartments is hampered by dislocation of elements during sample preparation. In this study the different stages of the preparation were evaluated as possible sources of artifacts. After improvements of the sample preparation procedure, sharp ion concentration gradients within heart tissue preparations were obtained, indicating no noticeable ion dislocation at the scale of the measurements.

Mit den bisher verfügbaren Hochfrequenzstromelektroden mußte jedoch entweder eine hohe Blutungsrate (Standardschlinge oder eine stark reduzierte Gewebeablation (Elektrovaporisation in Kauf genommen werden. Zur Optimierung der TUR-P wurde Rotoresect entwickelt. Rotoresect besteht aus einem speziellen Arbeitselement, bei dem eine Gewebefräskopfelektrode durch einen Mikromotor aktiv angetrieben wird. Im Anschluß an eine Phase 1-Studie mit 20 Patienten wurde in einer Phase 2-Studie an 20 Patienten eine transurethrale Rotoresektion der Prostata durchgeführt. Das durchschnittliche Prostatavolumen (TRUS betrug 44,0 ± 15,4 ml. Die rotierende Gewebefräskopfelektrode ermöglicht eine Gewebekoagulation, -vaporisation und eine zusätzliche mechanische Ablation.

    In contrast to positron emission tomography/computed tomography (PET/CT), the currently available single photon emission computed tomography/computed tomography (SPECT/CT) systems are very heterogeneous. On the side of the gamma cameras, dual-head systems are established, which are not very different from one manufacturer to the other. For the CT component, there are low dose tubes on the one side and flat detector-based cone beam CT and multislice-CT on the other. The CT image data can be used for anatomic correlation of suspicious findings as well as for attenuation correction of SPECT data. Attenuation correction enables on the one hand enhancement of SPECT image quality and on the other hand quantification of the radioactivity concentration becomes possible. Modern iterative reconstruction algorithms allow scatter correction and attenuation correction of SPECT data using the density values from CT. It still has to be shown to what extent attenuation-corrected whole body SPECT/CT studies will be able to improve the sensitivity of scintigraphy studies. As SPECT/CT primarily aims at morphologic correlation and not detection of additional lesions, an attempt should be made to balance the necessary anatomic information and the additional radiation exposure. Besides SPECT-guided CT all technical possibilities for dose reduction should be exhausted. (orig.) [German] Im Gegensatz zur Positronenemissionstomographie/Computertomographie (PET/CT) sind die auf dem Markt angebotenen Single-photon-emission-computed-tomography/CT(SPECT/CT)-Systeme sehr heterogen. Auf der Seite der Gammakameras sind Zweikopfsysteme etabliert, die sich bei den verschiedenen Wettbewerbern nur unwesentlich unterscheiden. Hingegen reicht bei der CT-Komponente die Palette von der einfachen Niedrigdosisroentgenroehre ueber die flachdetektorbasierte Cone-beam-CT-Technologie bis hin zum Mehrzeilenspiral-CT. Die CT-Bilddaten werden dabei zum einen zur anatomischen Korrelation funktionell auffaelliger Befunde verwendet, koennen aber auch fuer eine Schwaechungskorrektur der SPECT-Daten herangezogen werden. Neben einer qualitativen Verbesserung der SPECT-Bilder eroeffnet sich damit nunmehr die Moeglichkeit der Quantifizierung der Radioaktivitaetskonzentration. Moderne iterative Rekonstruktionsalgorithmen erlauben unter Verwendung der Dichteinformation aus den CT-Daten eine Streu- und Schwaechungskorrektur der SPECT-Daten. Inwiefern sich die Sensitivitaet szintigraphischer Untersuchungen durch den Einsatz schwaechungskorrigierter Ganzkoerper-SPECT/CT-Aufnahmen erhoehen laesst, muss erst in entsprechenden Studien gezeigt werden. Da bei der SPECT/CT nicht das Auffinden zusaetzlicher Radionuklidspeicherungen, sondern die morphologische und damit verbunden die artdiagnostische Zuordnung das primaere Ziel darstellt, sollte auf die Ausgewogenheit notwendiger morphologischer Information und erforderlicher zusaetzlicher Strahlenexposition geachtet werden. Neben der SPECT-gefuehrten CT sollten auch alle technischen Moeglichkeiten der Dosisreduktion ausgeschoepft werden. (orig.)

[German] Die VNG-Verbundnetz Gas AG (VNG) betreibt das groesste ueberregionale Ferngasnetz in den neuen Bundeslaendern und versorgt regionale und kommunale Energieversorgungsunternehmen sowie industrielle Abnehmer und Kraftwerke. Fuer diese Anlagen existieren ca. 300.000 Dokumente, die entsprechend ihrem Erzeugungsdatum in verschiedener Groesse, Ausfertigung und Gueltigkeit vorliegen. Ausgehend von der Bedeutung der Dokumentation fuer die Betriebsfuehrung der Anlagen wurden Mitte der 90er Jahre erste Schritte zur durchgaengigen Verbesserung des Umgangs mit der technischen Anlagendokumentation eingeleitet und mit der Einfuehrung eines EDV-gestuetzten Anlagendokumentationssystems (ADS) begonnen.

    How different land uses change CO2-fluxes under similar climatic conditions is a core question concerning the estimation of carbon sinks. Here, the TUD-cluster forms an excellent basis since it provides long-term measurements of Eddy-Covariance fluxes for different land uses. Measurements started at the Anchor Station Tharandter Wald (Spruce) in 1996. Since then the TUD-cluster has been successively complemented by continuous greenhouse gas flux observatories at Grillenburg (grassland), Klingenberg (crop rotation) and Spreewald (wetland), which have been operated since 2002, 2004 and 2010. The results of the TUD-cluster have been shared internationally in research frameworks such as EUROFLUX and subsequent research frameworks and is now part of ICOS-D (Integrated Carbon Observation System), the German branch to ICOS Europe. This contribution focuses on the presentation of the different sites with comparatively similar climatic conditions but different CO2-fluxes, water fluxes and energy fluxes. Influences of management and climatic conditions will be shown which are apparent in long-term data as well as interesting aspects of distinct land uses.

    The geothermal heat exchanger transfers heat geothermal heat through the metal wall of the outer pipe to the circulating water. The clean water heats up on its way down and is then pumped up again through the insulated inner riser pipe. The heated water is used for district heating. Drilling started on 26 March 1994, and the system was commissioned on 10 November 1994. Today, it supplies heat and warm water to about 1100 apartments. During its first year of operation the Prenzlau geothermal heat exchanger, which is 2800 m deep, covered more than 20 % of the heat demand of the Prenzlau-West district heating grid. The seasonal performance factor in continuous operation of the 500 kW system is between 8 and 12 % of the weather-dependent peak load, with hourly peaks of more than 700 kW. (orig./AKF) [Deutsch] Die Erdwaermetiefensonde nutzt die Waermeuebertragung vom warmen Erdreich durch die Metallwand des Aussenrohrs zum darin zirkulierenden Wasser. Das eingeleitete saubere Wasser erwaermt sich an der aeusseren Rohrwandung auf dem Weg nach unten und wird dann im inneren waermeisolierten Steigrohr an die Oberflaeche befoerdert. Das erwaermte Waser wird in Prenzlau ueber eine Waermepumpe zu Fernwaermezwecken benutzt. Am 26.3.1994 begannen die Bohrarbeiten, und am 10.11.1994 ging die gesamte Anlage in Betrieb, die heute ca. 1100 Wohnungen mit Waerme und Warmwasser versorgt. Die Erdwaermetiefensonde Prenzlau mit einer Tiefe von 2800 m deckte in den ersten beiden Betriebsjahren ueber 20 % des Waermebedarfs des Fernwaermenetzes Prenzlau-West. Die Jahresdauerleistung der Erdwaermetiefensonde mit 500 kW liegt bei 8-12 % der witterungsbedingten Jahreshoechstlast. Die Sonde gestattet Spitzenleistungen im Stundenbereich von mehr als 700 kW.

    Full Text Available A changing approach to social responsibility: a historic-normative case study of the North-West University (Potchefstroom Campus As a direct consequence of its Christian character, the former Potchefstroom University for Christian Higher Education (PU for CHE engaged in local corporate responsibility programmes for a number of decades. When the PU for CHE was merged at the end of 2003 to become the North-West University (NWU (including the PU for CHE which emerged in 2004, these programmes continued at the Potchefstroom Campus, but were stripped of their Christian grounding. Now the University has a “value-driven” approach. This article tracks the changes to the normative character as well as the continued changes to the university’s position on social responsibility. It was found that the North-West University’s normative points of departure have yet to be linked clearly to its community activities, and that formal corporate social responsibility (CSR activities must be clearly differentiated from normal university business as well as student activities such as rag. It is argued that the problematic overlapping of profit-generating activities should be distinguished from all CSR programmes and the contribution of sponsors disclosed at all times. Developments late in 2008 seemed to indicate that some of the most important problem areas be addressed when a new approach to “community engagement” is fleshed out. This could result in the NWU achieving the CSR goals set by both government and the University itself regarding its so-called do-values and developing a guiding philosophy on “community en-gagement”.

    Hydrothermal Carbonization (HTC) is a process which converts biomass of vegetal origin into a material comparable to brown coal. The HTC process is performed with biomass suspensions in a pressure vessel under temperatures of 180-250 C and just needs some hours. Starting with an overview of the present state of knowledge about HTC reactions the paper presents the results of a research project funded by the DBU (Deutsche Bundesstiftung Umwelt) which has shown the suitability of the HTC-process for a broad spectrum of organic municipal wastes. In particular wastes and residues of high water content are predestined for conversion via HTC. HTC-Biocoals show a high calorific value and can be energetically utilised accordingly. A basic advantage is seen in the excellent dewatering properties of these biocoals. Reaction temperature, reaction time and process management can determine yield and properties of HTC-Biocoals to a certain degree. Practical implementation of HTC has to consider aspects like utilisation of the exothermic nature of the process, process water treatment and concentration of contaminants in different HTC-product phases.

    Self-excited rotor whirl represents a serious hazard in the operation of turbomachines. The reported investigation has, therefore, the objective to measure the lateral forces acting on the rotor and to determine the characteristic pressure distribution in the rotor clearance area. A description is presented of an approach for calculating the leakage flow in the case of an eccentric rotor position on the basis of empirical loss coefficients. The results are reported of an experimental investigation with a turbine stage, taking into account a variation of the clearance characteristics. The pressure data measured are consistent with the theoretical considerations.

    This project started on 1 January 1996 with DM 3.7 million funds from the BMFT. Originally scheduled for three years, it was extended by a further 11 months for various reasons. Its intention was to reduce the cost of future solar thermal power plants. Particular emphasis was given to the parabolic trough technology asit is closest to commercialisation. Three strategies were involved: 1. Further development and qualification of components for the parabolic trough collector (WG PAREX); 2. Development of instruments for measuring radiation flux distribution in parabolic trough collectors (WG PARMESAN); 3. Development, verification and application of software tools for analysing the complex dynamic response of solar thermal power plants (WG SISTA). [German] Das hier dargestellte Projekt begann am 1.1.1996 und wurde vom Bundesministerium fuer Forschung und Technologie (BMFT) mit etwa 3,7 Mio. DM gefoerdert. Es hatte eine geplante Laufzeit von drei Jahren, wurde aber aufgrund von unterschiedlichen Verzoegerungen (Mitarbeiterwechsel, Defekte an Versuchsanlagen) kostenneutral um 11 Monate verlaengert. Gesamtziel des Projekts war es, zur Kostensenkung bei zukuenftigen solarthermischen Kraftwerken beizutragen. Dabei stand insbesondere die Parabolrinnentechnik im Vordergrund, da sie im Vergleich zu anderen solarthermischen Technologien einer weiteren kommerziellen Vermarktung derzeit am naechsten steht. Es wurden drei Schwerpunkte verfolgt: 1. Die Weiterentwicklung und Qualifizierung von Komponenten fuer den Parabolrinnenkollektor (Arbeitspaket 'Parabolrinnenexperimente', kurz PAREX) 2. Die Entwicklung von Messtechnik zur Bestimmung von Strahlungsflussverteilung bei Parabolrinnenkollektoren (AP 'Parabolrinnen-Messanlage', kurz PARMESAN) 3.

    Germany is an international leader in the development and introduction of renewable energy, i.e. wind and solar (photovoltaic) energy. Both technologies already contribute more than 13 % to national electricity generation. The political support of renewable energies resulted in a variety of different technologies the development of which has not yet been exhausted. The paper describes the state of the art of these technologies as well as selected development tendencies. New technologies can be introduced in a highly developed society only if questions according to their environmental impact are also answered.

    Currently decentralized electrical generation units (DG units) are connected to the network in Europe with an increasing number and generation capacity. Currently the operator of a DG unit or the availability of fluctuation primary energy determines the power and time of the generation fed into the grid. The distribution system operator (DSO) is blind'' towards the current power of the DG units in his grid because of the lack of observability and controllability of these generators in the low voltage level. Therefore a new strategy for the integration of DG units into grid operation will be required. This strategy will include energy management with controllable generators as well as controllable loads. In the concept developed in the project DINAR the point of common coupling (PCC), which acts as the technical as well as legal interface between grid operator on the one side and operator of the generator on the other side, will be extended by a communication interface. This allows a technically efficient design of an energy management system and avoids fundamental organizational changes to the current grid regime. The design of such a bidirectional energy management interface as a new implementation of the PCC is also presented within the article. (orig.)

    To begin with, an outline is given of the physical fundamentals, the data processing procedure, and the structure of the various scanning systems. The authors give only general information on these as detailed descriptions are offered by the producers. Practical hints are given on positioning of patients and on data documentation which have been tried with good results at the authors' institutions. As regards the description of normal anatomical structures, only one planigraphic angle is described as there are atlases presenting all possible planigraphic planes and angles. However, the changes in shape of anatomical structures are described for different angles. The chapter on interpretation is based on the information to be recognized on the pictures. Considerations for differential diagnoses are listed for every single parameter. A diagnosis of probability ought to be possible merely on the basis of the data, without any clincial information. Anamnesis and clinical findings are required to increase diagnostic reliability. In the last chapter, the CT pictures of intraeranial, neurological diseases are presented. Besides typical pictures, also non-typical and infrequent findings are given.

    In the future, the price pressure and cost pressure clearly will strengthen in the case of photovoltaic. On the one hand, this is due to an intensified degression which is intended in the context of the novella of the Renewable Energy Resources Act. On the other hand, the competition clearly will intensify with increasing availability of silicon. In this background, the technological development must be further accelerated energetically by research activities of enterprises just by the application oriented research promotion of the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (Dessau, Federal Republic of Germany) and the fundamental oriented promotion of the Federal Ministry of Education and Research (Berlin, Federal Republic of Germany). Germany is set up excellently according to the launching instruments on the one hand and in national comparison on the other hand.

    The transformation of the energy system to a de-carbonized energy supply requires a coordinated interaction between the sectors electricity, heat and transport. Thereby, the coupling of the electricity sector with the heating sector is one of the key measures in the transformation. The inclusion of wind and solar energy in the grid can be optimized by exact feed in forecasts, the coupling to the heat sector by means of heat pumps and power-to-heat (heater) allows more flexibilisation of the demand side. This interaction is made possible by intelligent solutions of systems engineering and power management. The development of appropriate incentives, market mechanisms and business models is also required, to make this coupling also economic successful. The contribution present die 80% scenario for the year 2050 created in the research project ''Interaction RES electricity, heat and transport'' and gives examples of future requirements and developments on this topic. [German] Die Transformation des Energieversorgungssystems zu einer de-karbonisierten Energiebereitstellung bedingt ein koordiniertes Zusammenspiel der Sektoren Strom, Waerme und Verkehr. Dabei ist die Kopplung des Stromsektors mit dem Waermesektor eine der entscheidenden Massnahmen bei der Transformation. Die Aufnahme von Wind- und Sonnenenergie in das Netz kann durch genaue Einspeiseprognosen optimiert werden, die Kopplung zum Waermesektor mittels Waermepumpen und Power-to-Heat (Heizstab) ermoeglicht die weitere Flexibilisierung der Nachfrageseite. Diese Interaktion wird durch intelligente Loesungen der Systemtechnik fuer das Energie- und Netzmanagement ermoeglicht. Die Entwicklung von entsprechenden Anreizsystemen, Marktmechanismen und Geschaeftsmodellen ist ebenfalls erforderlich, um diese Kopplung auch wirtschaftlich erfolgreich zu gestalten.

    Essent Netwerk Noord has decided to adopt a radically different approach for maintenance and new construction of its power grids. The grid company is now trying to analyse the risks it runs before actually starting a project. Since all risks are known simultaneously, the grid company is able to select those projects yielding the greatest risk reduction per euro. [Dutch] Essent Netwerk Noord heeft het onderhoud en de nieuwbouw van zijn netten over een radicaal andere boeg gegooid. Het netwerkbedrijf probeert nu eerst te achterhalen welke risico's het loopt alvorens een project te starten. Omdat alle risico's tegelijkertijd bekend zijn, kan het netwerkbedrijf die projecten selecteren die de grootste risicoreductie per euro opleveren. Daarvoor moet het management wel eerst aangeven welke risico's aanvaardbaar zijn, terwijl ook een forse investering in informatietechnologie nodig is.

    Full Text Available J H J A Greyvenstein, Professor 1917-1945 - paving the way for a critical and historical understanding of the New Testament at the University of Pretoria J H J A Greyvenstein was the first lecturer in New Testament Studies at the TUC, which later became the University of Pretoria. His understanding of the New Testament witnesses to a critical and historical scientific consciousness. The aim of this article is to argue primarily from Greyvenstein’s lectures, given during the first years of theological training at the TUC, that he paved the way for studying the New Testament from a critical and historical exegetical perspective. This perspective was accompanied by faith that can be described as an absolute dependance on God in pursuance of Jesus’ sonship experience.

    It is advisable to analyse different alternatives of the generation and supply of electrical energy and thermoelectricity with renewable forms of energy, because the demand of fuels (e.g. coal and oil) and the energy costs rise continuously. Technical optimization and cost-effectiveness of the different alternatives are the most important points of tests. This was the reason why at the Department of Mechanical and Energy Engineering of the Leipzig University of Applied Science a test ground ''renewable forms of energy'' has been built up step by step for thirteen years including two photovoltaic systems with different tracking systems, two wind-mills, an air-water-heat-pump and a dish-stirling-system.

    55% of all roads at RAG are driven by drilling and blasting operations. The Ibbenbueren mine is an exception, because 100 % of all roads are driven by drilling and blasting operations. The combined support type A has been adopted to an increasing extent in support technology in the last ten years. The Ibbenbueren mine is also a pioneer in this respect because the first drivage with Combi support type A was undertaken 25 years ago and in addition to exclusively bolted supports Combi support type A is currently introduced for 95 % of the supports. The standardised drivage and support system at the Ibbenbueren mine is described, optimisation potentials in the blasting operations, but also in bolting technology by means of the Lean Processing Improvement programme being indicated.

    The gas cavern storage facility in Empelde came into operation with three caverns between the early and the middle nineteen-eighties and is subject to a surface and subsurface extension since 2004. The subsurface extension comprises the construction of two new caverns (K4 is operated since 2009, K5 in leaching process since 2010) and the leaching extension as well as repair works of both existing caverns K2 (since 2012 in gas operation again) and K1 (is being re-leached since the end of 2012). The volumetric extension process of cavern K2 took place in three steps: flooding, releaching, gas re-filling. The flooding with water through a 4 1/2'' tubing were implemented discontinuously alternating with phases of gas withdrawal through the annulus 4 1/2'' x 9 5/8'' in order to minimize the risk of hydrate formation. The length of the individual phases mainly depended on the gas demand/consumption of the storage users. Water injection has been made in a gas well-head pressure range above the hydrostatic pressure of the water column in order to keep it stable at any time and to keep the cavern pressure high. The cavern volume increased by 12% because of the flooding. For the re-leaching process the existing 9 5/8'' tubing was pulled out and the permanent packer was milled. By using leaching strings 6 5/8'' x 10 3/4'' a maximum leaching rate of 300 m{sup 3}/h was realized and within 10 months an additional volume of 212,500 m{sup 3} was created according to the evaluation of the leaching process. Due to the geological affected development of the cavern shape the 6 5/8'' leaching string had to be pulled from sump level to the middle of the cavern height. In the course of the repair process and the new completion of cavern K2 with considerable time consumption the lower 33 m of the 13 3/8'' casing were milled for integrity purposes and the packer with the 9 5/8'' welded tubing was correspondingly set at a higher level. The gas re-filling went without any difficulties apart from the contact of the leaching string with the sump at the beginning of the re-filling process. The produced volume of brine, as expected, was far above the volume of the sonar measurement (+76,500 m{sup 3}) and only slightly higher than the volume of the evaluation of the leaching process (+17,000 m{sup 3}), which is due to the irregular cavern shape caused by hard salt layers (Kieserite).

    Due to the introduction of direct marketing and flexibility premium of renewable energy by the Renewable Energy Act 2012 (EEG 2012), incentives were created to favour a more demand-oriented power supply from biogas plants (BGA). The decision for such an operational mode depends on on-site conversion units on the economic outcome of the plants throughout the whole operating time. To install new plants or transfer existing plants into a flexible mode of operation, investments in additional and more efficient combined heat and power plants (CHP), in additional gas and/or heat storage and other technical components are necessary. The analyses show that the flexibility premium, as an extra of the market premium model, creates the greatest incentive for a more flexible generation of electricity from biogas. In addition, an intelligent management optimization can generate additional revenues on EPEX SPOT SE and balancing energy market. The additional revenues of more demand-oriented power supply from biogas plants are highly dependent on plant-specific conditions. From an economic perspective, a duplication of the installed electrical capacity seems to be the most beneficial option for a transition to a demand-driven operation mode of an average biogas model plant under the current legal framework (EEG 2012).

    Patients with severe, life-threatening trauma require a fast and accurate clinical and imaging diagnostic workup during the first phase of trauma management. Early whole-body computed tomography has clearly been proven to be the current standard of care of these patients. A similar imaging quality can be achieved in the multiple trauma setting compared with routine imaging especially using rapid, latest generation computed tomography (CT) scanners. This article encompasses a detailed view on the use of CT in patients with life-threatening trauma. A special focus is placed on radiological procedures in trauma units and on the methods for CT workup in routine cases and in challenging situations. Another focus discusses the potential of dose reduction of CT scans in multiple trauma as well as the examination of children with severe trauma. Various studies have demonstrated that early whole-body CT positively correlates with low morbidity and mortality and is clearly superior to the use of other imaging modalities. Optimal trauma unit management means a close cooperation between trauma surgeons, anesthesiologists and radiologists, whereby the radiologist is responsible for a rapid and accurate radiological workup and the rapid communication of imaging findings. However, even in the trauma setting, aspects of patient radiation doses should be kept in mind. (orig.) [German] Polytraumatisierte Patienten beduerfen im Rahmen der initialen Schockraumversorgung einer schnellen und exakten klinischen und bildgebenden Diagnostik. Fuer ein optimales Schockraummanagement ist heute die essenzielle Bedeutung einer zeitnah durchgefuehrten Ganzkoerper-CT unbestritten. Insbesondere durch schnelle CT-Scanner der letzten Generationen kann im Rahmen der Schockraum-CT eine aehnlich gute Bildqualitaet wie in der Routinediagnostik erzielt werden. Dieser Artikel beleuchtet den Einsatz der CT im Schockraum bei polytraumatisierten Patienten, wobei das Hauptaugenmerk auf Methoden des radiologischen Managements sowie auf den verschiedenen Moeglichkeiten der Untersuchungsdurchfuehrung im Routineeinsatz und in Spezialsituationen liegt. Ein weiterer Schwerpunkt sind Moeglichkeiten und Strategien zur Dosisreduktion der Schockraum-CT sowie der Untersuchung polytraumatisierter Kinder. Zahlreiche Studien haben gezeigt, dass eine fruehe Ganzkoerper-CT-Untersuchung positiv mit einer niedrigen Mortalitaet und Morbiditaet korreliert und anderen Bildgebungsverfahren deutlich ueberlegen ist. Die optimale Schockraumversorgung erfordert eine interdisziplinaere Zusammenarbeit von Unfallchirurgen, Anaesthesisten und Radiologen, wobei die Radiologie fuer einen raschen und adaequaten Einsatz der bildgebenden Verfahren und die zeitnahe Kommunikation relevanter Befunde verantwortlich ist. Daneben sollte auch im Rahmen der Schockraum-CT die Patientenstrahlendosis im Hauptaugenmerk des Radiologen stehen. (orig.)

    For analysis and evaluation of acoustical signals from technical processes different approaches are used. In the field of non-destructive testing and acoustic diagnostics signals are increasingly complex. The following paper presents approaches for the automatic classification of technical signals for typical examples. Signals with higher complexity require more performant algorithms like DTW (Dynamic Time Warping) and HMM (Hidden-Markov-Models), which are already applied successfully in speech processing.

    To reduce the time from symptom onset to treatment with tissue plasminogen activator (tPA) in ischemic stroke, an ambulance was equipped with a CT scanner. We analyzed process and image quality of CT scanning during the pilot study regarding image quality and safety issues. The pilot study of a stroke emergency mobile unit (STEMO) ran over a period of 12 weeks on 5 weekdays from 7a. m. to 6:30 p. m. A teleradiological service for the justifying indication and reporting was established. The radiographer was responsible for the performance of the CT scan on the ambulance. 64 cranial CT scans and 1 intracranial CT angiography were performed. We compared times from ambulance alarm to treatment decision (time of last brain scan) with a cohort of 50 consecutive tPA treatments before implementation of STEMO. 62 (95 %) of the 65 scans performed had sufficient quality for reading. Technical quality was not optimal in 45 cases (69 %) mainly caused by suboptimal positioning of patient or eye lense protection. Motion artefacts were observed in 8 exams (12 %). No safety issues occurred for team or patients. 23 patients were treated with thrombolysis. Time from alarm to last CT scan was 18 minutes shorter than in the tPA cohort before STEMO implementation. A teleradiological support for primary stroke imaging by CT on-site is feasible, quality-wise of diagnostic value and has not raised safety issues. (orig.)

    Facades are not only a shell of the protected habitats and a boundary between the indoor climate and the environment of buildings. Facades also convert from previously passive elements to active building systems which perform various functions of the room conditioning (heating, cooling, ventilation, lighting, and so on). The associated increased demands on the system integration into facades require new solutions for the planning, implementation and operation of these innovative systems. Within the intelligent handling of increasing complexity, superior automation strategies have to be developed by means of facade automation. These automation strategies have to match the individual functions with each other, and to ensure a building sector comprehensive functionality. Furthermore, another criterion for the design of integrated facade systems is the consideration of the user's feeling with respect to comfort as well as the user's control and user's acceptance. In line with the research project AUTiFAS (= Automation of innovative facade systems), different automation strategies of the facades and room automation are considered on the basis of metrological investigations and simulation analyses. For this purpose, an innovative facade element with a decentralized ventilation unit and an integrated sunshade had to be integrated into a test room initially. The functionality and the constructional tightness of the total test stand had to be verified and matched to the requirements of the tests. With the objective to develop a standardized description of the control and regulation functions of the building sector comprehensive automation strategies, an automation library was developed based on standard structures and forms of representation using a test facade as an example. The standards DIN EN 15232, IEC 61131 as well as the guidelines VDI 3813 and VDI 3814 provide the fundamentals. The developed automation strategies form the basis for the development of new control strategies of high quality. Two approaches of highly qualitative control methods were examined in this research project. The picking up of comfort criteria in the optimized control enables the consideration of user's needs. Another approach is the predictive control which is based on characteristic line models and aims a more energy-efficient operation.

    About one third of all German shopping centers are more than 30 years old and require revitalization. The necessity of revitalization does not depend on age but on the profit made by the shopping center. It can be stated that revitalization measures must be made in ever shorter intervals, owing to the more rapidly changing wishes of the customers. Further, there are different time intervals for different service areas. (orig.)

    Purpose: Percutaneous endoscopic gastrostomy (PEG) and percutaneous radiologic gastrostomy (PRG) are the standard methods of ensuring long-term enteral food intake in patients with dysphagia caused by neoplasia or neurological disorders. High-grade obstructions of the upper digestive tract or inadequate transillumination can prevent PEG. CT-guided percutaneous gastrostomy (PG) represents a special technique for enabling gastrostomy in patients for whom the endoscopic method is impossible. The aim of this study was to evaluate the results and complications of CT-guided percutaneous gastrostomy. Materials and Methods: CT-guided PG was performed in 83 patients, mostly with malignancy of the upper respiratory or digestive tract. Medical records for these patients were reviewed, and the results and complications of the CT-guided PG were analyzed retrospectively. Complications were grouped into four categories: Major and minor complications as well as early and late complications. Results: In 95.2 % of all cases (79/83), CT-guided PG was successful in the first attempt. Within the first 3 days, 5 major complications including 4 tube dislocations and one case of peritonitis were found in 4/79 patients (5.1 %). One of these patients experienced two early major complications. Early minor complications, mainly local skin irritations and temporary stomachache, were observed in 31 patients (39.2 %). Three days after CT-guided PG, 4 cases of major complications were documented, yielding a total rate of major complications was 8.7 % (7/79). Hemorrhage requiring blood transfusion or perforation after gastrostomy was not observed. 29.1 % of the patients (23/79) experienced late minor complications. (orig.)

    To protect climate, the aviation industry is asked to reduce GHG emissions. A possible measure to achieve this goal is the increased use of biokerosene. One possible way to provide biokerosene is through liquefaction of biomethane. This biomethane can be produced by anaerobic fermentation from large variety of organic waste streams. Considering this background, an overview of the overall process chain for the production of biokerosene from biomethane is given. The starting point for the analysis is the Gasto-Liquid-process (GtL). This process is described in detail focusing on the differences between autothermal and steam reforming of biomethane. Based on this, two reference concepts are designed, modeled, and simulated. The results of this simulation are then evaluated according to predefined technical parameters. Finally, the defined concepts are analyzed economically, i.e. the production costs are assessed and the key parameters defining the results are identified.

    Electricity consumption in German households accounts for more than 10% of energyrelated CO{sub 2} emissions. In spite of substantial improvements in, for example, the efficiency of household appliances, there is still a considerable electricity savings potential to be tapped in this sector. The possible contribution that the German residential sector can make to climate protection is correspondingly large. This working paper aims to structure and quantify electricity savings potentials which could be exploited in German households either through investment measures or changed user behaviour. The total theoretical potential which can be tapped through the purchase of efficient household appliances and the replacement of electrical heaters and hot water generators (i.e. by encouraging investment) amounts to approx. 90 TWh/a. This corresponds to more than 60% of the current electricity demand of all German households. By means of changed user behaviour, approx. 30 TWh of electricity could be saved according to our calculations. The assessment of energy savings potentials is an important step towards identifying those potentials which are most significant with regard to their volume, the barriers against their deployment and the design of appropriate policy. The results of the analysis give indication which areas should be dealt with as a matter of political priority in order to maximise the effects of political instruments in the area of demand side related electricity efficiency.

    The contribution under consideration reports on a supply of an infrastructure for the generation of a comprehensive integrated information system for tenants, landlords and providers. With the prototypical acquisition of building conditions and the input of relevant data in a local data base, technical obstacles already have been overcome. The planning and partial implementation of the local data base for the targeted and structured acquisition of inventory data supports a holistic view of all energy-related processes. The comprehensive analysis of all building management processes and future goals of information by all participants is the basis for high quality data. The system concept is designed so that a global data base is created. This database allows observations of the user behaviour, efficiency and costs, and an assessment of technical components such as durability and contribution of energy efficiency. Cross-sector relationships are revealed by means of analytical methods such as data mining.

    The trend to torque motors does not only continue since the beginning of a new millennium, but is still increasing at the moment. This development is essentially pushed by branches of producing industries, e.g. plastics, printing, wire drawing and machine tool industry. The replacement of hydraulic drives by electric drives e.g. with plastics machines step by step means a first essential step towards the right direction, particularly this development is seen from the angle of energy consumption. The high torques and low speeds of the hydraulic drives can be produced by gear motors for example. Meanwhile torque motors become standard program of numerous manufacturers, so that, by its application, there are not only advantages of direct propulsion technology to reach in principle, but also reductions of processing times and energy consumption. In consideration of less marginal condition the relationship of moment of inertia and accelerating values achieved by torque motors in comparison to gear motors is derived and based on performed motors the energy efficiency assuming different load cycles is compared.

    The authors of the contribution under consideration present a platform for the active participation of consumers and producers at the decentralized energy market with dynamic pricing of the electricity. A profitable operation of these prosumers is a prerequisite for their widespread market participation. The authors describe in detail the technical barriers for the market participation of the prosumer and develop a possible approach for the technical realization of the integrated market access. Markets with decentralized structures require a dedicated infrastructure of communication. In this case the proven key technology of the Internet Protocol is used. This requires an IP enabled network component in decentralized systems. The Internet-based connection of consumers and producers enables an automated participation in energy markets. In order to ensure a security of supply, such a scheme has to meet real-time criteria and high security requirements. When communicating via the Internet the accessibility of each plant from everywhere can be realized. This enables a cross-regional clustering of prosumers who otherwise would be excluded by market entry barriers to an active participation in the energy market. For the creation of a market any prosumer must have the free choice of the trading platform. The authors discuss the resulting additional demands on the system architecture.

    Purpose: to evaluate the technical and clinical success rates of percutaneous stent revascularization in the treatment of chronic mesenteric ischemia (CMI). Patients and methods: 17 patients (12 female) with typical symptoms of CMI were treated by percutaneous stent placement for stenoses of the splanchnic arteries (celiac trunk; superior mesenteric artery, SMA; inferior mesenteric artery, IMA). The primary and secondary technical success, primary and secondary clinical success, and the long-term clinical outcome were determined. Results: a total of 24 stents were implanted in 21 splanchnic arteries (12 stents in the celiac trunk, 11 in the SMA and 1 in the IMA). The primary technical success rate was 91% (19/21 arteries), the secondary technical success rate was 95% (21/22 arteries). Clinical follow-up was available for 16 patients. The primary clinical success rate was 81% (13/16 patients). Following two secondary interventions, the secondary clinical success rate was 94% (15/16 patients). Long-term clinical success was achieved in 15 of 16 patients (94%) with a mean follow-up of 26 months. One patient died within 30 days of the intervention and two patients demonstrated major complications (1 dissection, 1 stent dislocation). None of the patients required surgical revascularization and none of the patients died due to recurrent mesenteric ischemia. (orig.)

    Many flows relevant for climate research, weather forecasting, heating, ventilation, air-conditioning (HVAC), and fire safety are characterized by relatively small velocities compared to the speed of sound. The efficient computation of such low Mach number flows requires computational methods that avoid the Courant-Friedrich-Lewy time step restriction, based on the speed of sound. An essential issue in the context meterological flow modelling, as investigated at the Potsdam Institute for Climate Impact Research, is the construction of efficient numerical schemes for such flows that are in conservation form with respect to all physically conserved quantities, i.e., mass, momentum, and energy. Extending initial developments by Klein et. al [9, 13, 15, 19, 20], a new scheme for such flows is currently under development which accounts for flows in three space dimensions, is fully conservative, with second order accuracy and covers the entire regime 0 {<=} M {<=} 1. To transfer this scheme to practical applications, the author has created the programm code MOLOCH. This technical report collects the background theory of the scheme and describes the current state of its implementation. The code is based on a finite-volume method using a cartesian grid. Currently, the scheme is limited to Zero-Mach number. The first four chapters describe the mathematical background of the scheme. After a short presentation of the underlying set of equations, the result of a one-scale asymptotic analysis is discussed to elucidate the main problems in the context of constructing numerical simulation schemes, and to motivate the construction of the method. Chapter 5 describes the details of the numerical technique and provides additional information regarding the discretization and the implementation of boundary conditions. Chapter 6 describes the implementation of gravitational forces, necessary to run the falling droplet test case, which will be described in Chapter 7. An empirical convergence study confirms the predicted second order accuracy of the implemented scheme. Current work in progress aims at extending the scheme presented here to the meteorologically important class anelastic, instead of incompressible, flow models. The computational code structure as presented here will transfer to these applications without change. (orig.)

    This report documents the status of the research and development goals reached within the reactor safety research project RS1503 ''Development and Application of Neutron Transport Methods and Uncertainty Analyses for Reactor Core Calculations'' as of the 1{sup st} quarter of 2013. The superordinate goal of the project is the development, validation, and application of neutron transport methods and uncertainty analyses for reactor core calculations. These calculation methods will mainly be applied to problems related to the core behaviour of light water reactors and innovative reactor concepts. The contributions of this project towards achieving this goal are the further development, validation, and application of deterministic and stochastic calculation programmes and of methods for uncertainty and sensitivity analyses, as well as the assessment of artificial neutral networks, for providing a complete nuclear calculation chain. This comprises processing nuclear basis data, creating multi-group data for diffusion and transport codes, obtaining reference solutions for stationary states with Monte Carlo codes, performing coupled 3D full core analyses in diffusion approximation and with other deterministic and also Monte Carlo transport codes, and implementing uncertainty and sensitivity analyses with the aim of propagating uncertainties through the whole calculation chain from fuel assembly, spectral and depletion calculations to coupled transient analyses. This calculation chain shall be applicable to light water reactors and also to innovative reactor concepts, and therefore has to be extensively validated with the help of benchmarks and critical experiments.

    Not unlike thermoablation of liver metastases, thermoablation of metastases to the lungs is gaining clinical interest. Radiofrequency ablation and laser-induced interstitial thermotherapy are both used clinically. Initially it was suspected that percutaneous treatment of lung metastases would result in a rate of pneumothoraces and tissue reactions which would not be clinically acceptable. However, this did not prove true. Fear of pneumothoraces however did lead to the desire for an applicator with a maximally reduced diameter. While clinical results are not yet available, technical success rates of laser-induced interstitial thermotherapy of lung metastases are promising. The percentage of pneumothoraces does not differ significantly from that seen in diagnostic procedures. Large metastases may be treated by simultaneous use of multiple applicators or by repositioning of an applicator (pullback technique). Surgical experience is still guiding us in deciding which primaries' metastases may be successfully treated percutaneously. The literature indicates that lung metastases from colorectal primaries are especially suited. Radiotherapy is only an alternative method in cases of lung metastases if they cause symptoms (such as pain because of thorax infiltration or difficulty in breathing because of bronchial lesion). Due to the risk of radiation-induced pneumonia general radiotherapy is not to be recommended. The possibility of stereotactic ray treatment is being considered, but because breathing shifts the metastases it is not yet feasible. Therefore, percutaneous thermoablation could be used as a minimally invasive, rather riskless therapeutic option for a relatively high percentage of inoperable lung metastases. (orig.) [German] Die Thermoablation von Lungenmetastasen ist dabei, sich aehnlich erfolgreich im klinischen Alltag zu etablieren wie die heute weit verbreitete Thermoablation von Lebermetastasen. Bei beiden Metastasierungsformen kommen die Radiofrequenz-(RF-)Ablation und die laserinduzierte Thermotherapie (LITT) zum Einsatz. Befuerchtungen, dass die perkutane Behandlung von Lungenmetastasen zu nicht akzeptablen Pneumothoraxraten und nicht tolerierbaren Lungenreaktionen fuehrt, haben sich bisher nicht bestaetigt. Wegen der Gefahr eines Pneumothorax werden Zugangssysteme mit moeglichst geringem Durchmesser bevorzugt. Auch wenn klinische Ergebnisse derzeit nur in unzureichendem Masse vorliegen, existieren jedoch verlaessliche Zahlen zum technischen Erfolg der Methode. Die Pneumothoraxraten liegen insgesamt in dem Bereich, der bei diagnostischen Punktionen beobachtet werden kann. Groessere Metastasen koennen wie bei der Ablation von Lebermetastasen durch gleichzeitigen Einsatz mehrerer Laserapplikatoren oder durch konsekutive Umpositionierung eines Applikators behandelt werden. Zur Beantwortung der Frage, welche Primaertumoren eine erfolgreiche Behandlung von Lungenmetastasen zulassen, kann die chirurgische Literatur herangezogen werden. Gesichertes liegt hier v. a. fuer Lungenmetastasen kolorektaler Karzinome vor. Die Strahlentherapie stellt bei Lungenmetastasen nur dann ein Alternativverfahren dar, wenn diese eine Symptomatik verursachen (z. B. Schmerzsymptomatik bei Thoraxwandinfiltration oder Luftnot bei Bronchusalteration). Eine generelle Strahlentherapie ist bei Lungenmetastasierung aufgrund der Pneumonitisgefahr nicht zu befuerworten. Die Moeglichkeit einer stereotaktischen Bestrahlung wird zwar diskutiert, ist aber aufgrund der Atemverschieblichkeit der Metastasen derzeit noch nicht praktikabel geloest. Somit koennte die perkutane Thermoablation bei einem relativ hohen Prozentsatz nichtoperabler Lungenmetastasen als minimal-invasive, komplikationsarme Therapieoption eingesetzt werden. (orig.)

    Fuel cells open up a new and exciting option for energy conversion at high efficiency of fossil fuels into electrical energy with the minimum emission of noise and pollutants. The fuel cells which are of interest to the power plant builder are the phosphoric acid fuel cell (PAFC), the melting carbonate fuel cell (MCFC) and also the ceramic oxide fuel cell (SOFC), since, with these, high system efficiencies in the production of electrical energy can be obtained through the opportunity to utilize waste heat.

    This final report for the Swiss Federal Office of Energy (SFOE) presents a technical handbook on the principles and planning processes involved in designing and installing heating systems for low-energy and so-called passive houses with air-renewal systems and provides examples taken from practice. The manual is intended to provide guidance to architects, planners and manufacturers. In the first part of the three-part manual, the basics of energy balances, ecological assessment and modern control techniques are dealt with, the second part covers integral planning, feasibility and manufacturing techniques and the third part gives examples of three houses built to so-called 'Minergie' low-energy and 'passive house' standards. The factors to be taken into account when planning low-energy and passive houses heated with heat pumps are discussed and calculation tools aiding the dimensioning and simulation of the systems are introduced.

    The Second Technical Report of the project `Saisonal Storage of Solar Low Temperature Heat in Mines` describes different concepts to realize seasonal storage in mines and suitable district heat systems. The different storage designs and concepts are presented and evaluated in detail. The fundamental differences between the use of a tunnel or a shaft are discussed as well as the storage filling with a fluid or a mineral material. Technical solutions for the integration of a seasonal storage in mines are examined. Different solutions for storage sealing stand for choice. It is shown that the use of air-placed concrete represents a particularly suitable method due to the cost advantages and the flexible operation of the procedure compared with other seal systems. An exemplary system design leads to specific investment costs of 115 DM/m{sup 3} to 300 DM/m{sup 3} for the saisonal storage depending on the boundary conditions (tightness of the surrounding rock, use of available pipework etc.). The latter amount equals the height of the costs payed for the concrete underground tanks in Hamburg-Bramfeld and Friedrichshafen. It is shown that the costs for the use of mines for saisonal storage is comparable to those of existing systems at least; in favorable cases definitely lower costs may be achievable. In any case, a specific evaluation, taking account of local boundary conditions and circumstances, is necessay. On the basis of the boundary conditions below and the situation above ground, many locations in the Ruhr area were estimated concerning their suitability for this project. Favorable locations could be found within almost all coal industry areas. The plan for house buildings at these locations is suitable for the application of a district heat network. Although the examination of seasonal heat storage in mines is not concluded up to now, the presently achieved information indicates very positive results in all sections (i.e. investment costs, technical feasibility, choice of location).

    The First Technical Report of the project 'Analysis of Seasonal Storage of Solar Heat in Mines' describes the local terms of construction and operation of a shaft storage at the 'Bergwerk General Blumenthal/Haard' in Recklinghausen. For the installation of a pilot storage the Shaft No. 6 should be chosen because of the better condition of the shaft walling and the greater diameter in comparison with Shaft No. 2. As the result of the objective of operational reliability only the leakproof metal tubbing array in the shaft should be used. In compliance with this rule, a system with a volume of 2,155 m{sup 3} is designated for the Shaft No. 6 (storage height 63 m). The storage is only insulated at the top. A gravel/water filling guarantees static strength of the site. With a vertical distance of 1.5 m, 42 pipe coils should be installed, evenly distributed across the cross section and connected to 10 temperature-dependent controllable layers. Each pipe coil consists of 100 m steel pipes with an inside diameter of 2.5 cm. Simulation calculations show that storage efficiencies higher than 80% can be expected. The efficiencies and the discharged energy considerably depend on the temperature level of the district heat netowrk. The collector area and the quantity of heat have a comparatively smaller influence on the storage operation results. The specific investment costs of the shaft storage at the location 'General Blumenthal 6' were calculated to 477 DM/m{sup 3}. A reduction of the specific costs can be achieved especially by the use of larger storage volumes in the future. (orig.) [German] Im vorliegenden Bericht werden die Rahmenbedingungen fuer den Bau und Betrieb eines Schachtspeichers am Beispiel des Standortes Bergwerk General Blumenthal/Haard in Recklinghausen konkretisiert. Da der Schacht 2 in einem deutlich schlechteren Zustand ist und einen kleineren Schachtdurchmesser aufweist, ist es sinnvoll, den Schacht 6 fuer die Installation eines Pilotspeichers zu nutzen. Aufgrund des Zieles einer moeglichst hohen Betriebssicherheit sollte fuer den Schachtspeicher der eigendichte Abschnitt mit Tuebbingausbau, der in diesem Fall bis 70 m Teufe reicht, verwendet werden. Abzueglich eines unteren Ueberlappungsbereiches und des Schachtkellers ergibt sich somit eine nutzbare Speicherhoehe von rund 63 m, was einem Volumen von etwa 2.155 m{sup 3} entspricht. Der Speicher wird nur am Kopf waermegedaemmt. Der Schachtspeicher wird mit einer Kies/Wasser-Fuellung versehen. In diese werden mit einem vertikalen Abstand von 1,5 m insgesamt 42 Rohrschlangenebenen eingebracht, die jeweils aus gleichmaessig ueber die Querschnittsflaeche verteilten Stahlrohren DN 25 mit einer Gesamtlaenge von knapp 100 m bestehen. Diese Ebenen werden zu insgesamt 10 temperaturabhaengig ansteuerbaren Schichten zusammengefasst. Durchgefuehrte Simulationsrechnungen zeigen, dass ein Grubenspeicher im quasistationaeren Zustand Nutzungsgrade von ueber 80% erreichen kann. Die Nutzungsgrade und damit die nutzbaren solaren Waermemengen haengen vor allem vom Temperaturniveau des Nahwaermenetzes ab. Die Groesse der Kollektorflaeche und die Hoehe der Waermelast der Verbraucher haben nur einen vergleichsweise geringen Einfluss auf die Leistungsfaehigkeit des Speichers. Bei positiver, aber realistischer Einschaetzung der Randbedingungen ergeben sich fuer den projektierten Pilotspeicher am Standort General Blumenthal 6 spezifische Investitionskosten in Hoehe von 477 DM/m{sup 3}. Eine Verringerung dieses Wertes ist vor allem durch die Vergroesserung des Speichervolumens bei zukuenftigen Anlagen moeglich. (orig.)

    Diesel engines were actually designed for fossil fuels. For this reason an operation with substitute fuels poses a special challenge. For example native oils/fats are elements comprising a range of more than 5000 chemically different substances. Each of these has individual characteristics which have to be considered during operation. Hence, an adapted operation is necessary. Typical damages include: 1. Cavitation pitting in the fuel injection system. 2. Precipitation of combustion residues in inlet and outlet. 3. Engine damages caused by lube oil dilution. 4. Engine damages caused by agglutination of lube oil. 5. Plugging of fuel conduit and filter systems caused by polymerization reactions. Practice has shown that the operational mode of engines are not generally reproducible. It is a fact that engines of the same type and manufacturer show a different operating performance. This is due to catalytic effects which can be traced back to the consistence of the material grade. Traditionally the material grades of these engines are designed for basic fuels. In contrast to that most of the substitute fuels (oils/fats) have distinctive acidic characteristics. The question in how far the catalytically active surfaces boost or avoid polymerization is part of current researches. (orig.)

    The Dutch Office of Energy Regulation (DTe) plans to adjust the present regulations with regard to regional electricity network companies. In 2002 an integrated model for pricing and quality regulations is drafted, which is expected to be implemented in 2005. This report serves as input for such a model. Quality is defined in terms of electricity supply disruptions. The aim of the study on the title subject is to determine prices for different types of power supply disruptions. The study is based on a survey among 12,400 households and nearly 2,500 small and medium-sized businesses in the Netherlands. [Dutch] De Dienst uitvoering en Toezicht energie (DTe) is voornemens om de huidige regelgeving ten aanzien van de regionale elektriciteitsnetbedrijven aan te passen. Hiertoe zijn in 2002 verkenningen voor een geintegreerd prijs- en kwaliteitsreguleringsmodel opgesteld, dat naar verwachting begin 2005 worden ingevoerd. Dit rapport dient als input voor het kwaliteitsreguleringsmodel. Kwaliteit is hier gedefinieerd in termen van stroomonderbrekingen. Het doel van het onderzoek is om prijskaartjes vast te stellen voor verschillende soorten stroomonderbrekingen. Zo kunnen de onderbrekingskosten verschillen afhankelijk van bijvoorbeeld het tijdstip (dagdeel, dag van de week, seizoen), de duur van de onderbreking, het wel of niet ontvangen van een waarschuwing vooraf en het aantal onderbrekingen. Het onderzoek is gebaseerd op een enquete onder 12.400 huishoudens en bijna 2500 MKB-bedrijven.

    The use of electric tumble dryers in the Netherlands increases at a great pace. Holland Energy Systems (HES) developed a prototype solar wash dryer in which the advantages of open air drying and electric drying are combined. The dryer consists of a transparent plate with an air cavity behind it. On the innerside of the air cavity is a metal dark-colored plate, the absorber. Behind this solar collector is the actual drying space, equipped with mobile racks for the laundry. If the sun does not produce enough heat the outside air will be heated electrically. The dryer also contains a flat water tank to store heat at the bottom of the drying compartment. In this report attention is paid to the architectural implementation possibilities of the solar wash dryer and the adjustments that might be made in the design of a house. Next to architectural aspects also juridical and societal aspects are discussed, in particular concerning the fitting-in of the housing construction. figs., tabs., 5 appendices, 11 refs.

    Full Text Available [english] Purpose: Anatomy is an important subject in the education of radiographers and radiotherapy technicians. The enormous amount of information may render efficient learning more difficult and lead to sub-optimal results. The purpose of this study was to test whether the introduction of a computer-based tutorial enhances learning success in anatomy. Methods: A commercially available tutorial in anatomy especially adapted to the requirements of the education of radiographers and which facilitated and structured the frequent repetition of the material was introduced into the conventional curriculum. The tutorial was used during normal lessons, and work with it was obligatory. The students could learn anatomical structures and landmarks repeatedly as well as test themselves. The scores obtained in the final examinations two years prior to introduction of this tutorial were compared with those obtained two years after introduction. Results: Students’ knowledge in anatomy could be markedly improved. Conclusion: An efficient and time-saving method of learning became possible. It was important to integrate the tutorial into the normal curriculum. The test results show the feasibility of this educational concept. [german] Zielsetzung: In der MTA-Ausbildung nimmt Anatomie einen wichtigen Platz ein. Die große Stofffülle erschwert jedoch ein effizientes zeitsparendes Lernen und führt auch bei motivierten Schülern oft zu mangelndem Lernerfolg. Es sollte geprüft werden, ob dieser durch Einführung computerbasierten Lernens verbessert werden kann. Methodik: Ein auf die Erfordernisse der MTRA-Ausbildung von den Autoren angepasstes kommerzielles Anatomie-Lernprogramm, das den Schülern das notwendige häufige Wiederholen des Materials erleichtert und strukturiert, wurde im Rahmen des Pflichtunterrichtes den Schülern zur Verfügung gestellt. Diese konnten damit anatomische Sachverhalte sich einprägen, beliebig oft wiederholen und ihr Wissen testen. Die Examensergebnisse jeweils zweier Jahrgänge vor und nach der Einführung des Programms wurden verglichen. Ergebnisse: Durch die Einführung des Programms konnten die Anatomiekenntnisse von MTA-Schülern bei gleichem Zeitaufwand deutlich verbessert werden. Schlussfolgerung: Durch gezieltes Üben derjenigen Elemente, die noch nicht ausreichend im Langzeitgedächtnis verankert sind, war eine effiziente und zeitsparende Art des Lernens möglich. Wichtig ist eine Einbettung des eLearning-Tools in den normalen Unterrichtsablauf. Die deutlich besseren Examensergebnisse nach Einführung unserer Anatomie-Lernplattform sprechen für die Richtigkeit des Konzeptes.

    The German Umweltbundesamt (federal environmental agency) commissioned a cost-benefit analysis to be made, testing the practical performance of fuel cell-driven automobiles, for state-of-the-art assessment of their benefits and drawbacks as compared to other available automotive fuel systems. Results available so far of calculations based on the cost-benefit analysis show that the targets involved, such as cutback of emissions and conservation of resources, can be realised within the foreseeable future at much lesser expense through the use of fuel consumption-optimized Otto engines offering lowest emission levels (of the type ULEV, ultra-low emission vehicle, or EURO 4 standard), as compared to the relevant contributions to emission reduction and other targets offered by the fuel cell-driven automobiles.(orig./CB) [Deutsch] Das Umweltbundesamt hat die Brennstoffzellentechnik im Verkehr einer Kosten-Nutzen-Betrachtung unterzogen, um zu ermitteln, welche Vor- und Nachteile sie im Vergleich zu anderen Antriebskonzepten im Verkehr nach derzeitigem Wissensstand hat.

    The share of distributed renewable generation is dramatically growing since years in Germany due to the existing subsidies for renewable energy sources. As a consequence the existing distribution networks and primarily the low-voltage (LV) networks have to change to maintain the same degree of power quality and security of supply. This paper described resulting new challenges, which will have a major impact on the distribution networks. To solve the problems today utilities are mainly focussing on conventional measures, like network extension or adding new substation. Compared to this classical measures new solutions and technologies are described. These solutions shall enable the distribution network operators (DSO) to optimize the necessary investment costs. Finally the main described solutions will be evaluated and compared to the conventional measures using three typical and realistic LV networks. For each network the share of renewable energy is adjusted in different steps and the impact on the network is assessed taking into account the technical as well as the economic behaviour. (orig.)

    For the transition to a sustainable energy supply Germany anchored basic cornerstones in the EEG. In paragraph 2(2) of the EEG, the priority purchase, transmission and distribution of the electric energy by the network operator is controlled. From this for the Lechwerke AG results a completely new environment. The legal framework requires costly network expansion projects, especially in the network periphery in rural areas. For the distribution system operator the traditional grid extension is costly and time consuming. In search of alternative options, the use of ''network controller'' and ''950-V-lines'' is compared to the conventional grid extension. The measurements showed that the 20 kV grid upgrade is the ideal solution from a technical aspect. The improvement of the network situation is clearly evident in all measurements in accordance with DIN 50160. In turn, network expansion is the most expensive alternative and the costs often do not outweigh the benefits. Also the high costs for maintenance and operation have to be considered. Furthermore, often power reserves are created that may not be used. The 950-V line is a measure that improves the network situation. Considering the costs, this variant is the cheapest option, but only a maximum power of 30 kVA can be transmitted. The follow-up costs for maintenance and operation are significantly lower. The increase of the nominal voltage by the factor 2.3,8 in theory the short circuit power should increase by the factor (2.38){sup 2}. However this is not the case, since through the added impedance of the transformer the voltage increase in the cable pushes down the effect. The short circuit power is improved only by the factor 1.36. The power controller controls the voltage level (10-minute averages) quite well. However, flicker and voltage imbalance are increased. Harmonics are increased if they are caused by customers behind the power controller. The development of overvoltages due to the behavior of the controller under severe voltage dips have to be evaluated critically. If the electrical load is reduced or to the end of a power failure voltage values, which amount to well over 110% of the nominal voltage are caused by over-compensating of the controller. This can cause damage to equipment in customer installations and thus lead to demands for regress. In order to minimize these overvoltages at least for a fault in the MV and HV power grid, the response time of the network controller must be matched to the settings of the network protection devices. Thus, in these cases the occurrence of the overvoltages can be reduced, but cannot be avoided. Therefore, in practice the network controller can be used only in very limited cases, but in certain cases it is technically a good solution and can be implemented very quickly. Here, the current and future demand of electrical energy of the customers is crucial. The follow-up costs are also low. Finally, it should be noted that there exists no universal approach due to the advantages and disadvantages of each network expansion option. Yet for every network situation the appropriate network expansion option can be selected by considering the environmental conditions. If a single customer is connected via a long supply line and with low short circuit power then the 950-V-line is a feasible solution. If the criteria are sufficiently short-circuit power and customer-cased flicker and harmonics are small, the network controller can be used without difficulty. The network controller can also be considered for small local networks, due to the different offered devices. Are very isolated estates to supply, often the only possibility is a connection to the medium-voltage grid. (orig.)

    In 2009, important processes have been initiated which impact on the development of renewable energies in a long-term run. Two of these projects are the Desertic Industrial Initiative and the construction of a 2-GW solar power station in the People's Republic of China. The Desertec Industrial Initiative intends to cover 15 % of the european electricity requirement by means of about 400 billion Euro. It is the largest ever proposed project of renewable energy. In order to document the current knowledge and to make it available, the project group 'Renewable Energies' of the engineering insurer in the German Insurance Association has prepared this publication. This publication provides a current overview of the state of the art and the technical potential threat for the conversion of solar energy, wind energy, hydropower, geothermal energy and biomass into usable energy.

    After several years of low acceptance, miniature CHP systems are rapidly gaining ground in domestic power supply. Apart from the established technology of gas-fuelled CHP systems, there are also new incentives from legal regulations, e.g. the Reimbursement Act, the Act on Combined Heat and Power Generation of 2009, and the Act on Renewable Energy Sources. The contribution analyses the various modes of operation of miniature CHP systems in a low-voltage grid in an attempt to show the effects of enhanced decentral power generation on the public power supply grids.

    Climate change constitutes a huge challenge for humankind. Greenhouse gas emissions are still continuing to increase on a global scale. In order to limit the risks of global climate change, global average temperature must not rise more than 2 C above pre-industrial levels by the end of this century. If this target is to be achieved globally, Germany - like the other industrialised countries - must reduce its emissions of greenhouse gases by 40% by 2020 and by 80% by 2050 compared to 1990 levels. The German Federal Environment Agency (Umweltbundesamt, in short ''UBA'') banks on a sustainable climate protection policy through emission prevention and is therefore demanding that, as a priority, the change initiated in German energy policy - away from fossil fuels towards renewable energy sources and a marked increase in energy efficiency - should be consistently implemented and intensified, i.e. that emissions be addressed before they occur. For a limited time, there may also be a need to take end-of-pipe measures to reduce CO{sub 2} emissions. This may include certain forms of capture and storage of the most important greenhouse gas, carbon dioxide, often referred to as CO{sub 2} ''sequestration''. Although CO{sub 2} capture and storage does not prevent continued generation of greenhouse gases, it does promise to prevent their escaping into the atmosphere and, thus, their climate impact for extended periods of time. The Federal Environment Agency takes the view that for the use of such methods it is essential to also take into account their impact on other spheres of the environment and health issues. The Agency has developed a detailed opinion on these issues in a comprehensive position paper, which is available from October 2006 in German on the internet website of the German Federal Environment Agency www.umweltbundesamt.de/energie. This summary outlines the major conclusions. Both national and international aspects need to be considered in the discussion. Where national aspects are concerned, the Federal Environment Agency focuses on the situation in Germany, e.g. in addressing the question of available storage capacity for captured CO{sub 2}. This paper deals only with CO{sub 2} capture and storage, and not with biological (''terrestrial'') sequestration through, for example, forestation. (orig.)

    In December 2000 and January 2001 the current state of knowledge and experience of the combustion of meat and bone meal (MBM) and tallow was compiled and examined. Taken into account the existing regulations and recommendations, this report was written in order to provide guidance on techniques and standards for the thermal mal treatment of these materials. It is supposed to assist both operators of incineration plants and authorities to evaluate the suitability of a process and determine the necessary prerequisites. Lacks of knowledge are identified, and recommendations for gathering further information and experience are given in the report. The preparation of this report involved extensive discussions with representatives of incineration plants, governmental departments and MBM processing plants. The report includes physical and chemical data on MBM and tallow. It compiles the current experience with the combustion of MBM and offers requirements and recommendations. (orig.) [German] Im Dezember 2000 und Januar 2001 wurde der aktuelle Stand des Wissens und der Erfahrungen bei der Verbrennung von Tiermehl, Tierfett und sonstigen bei der Tierkoerperbeseitigung anfallenden Stoffe zusammengetragen und gesichtet.

    The new office building of the Federal Environmental Agency (Dessau-Rosslau, Federal Republic of Germany) was implemented as a pilot project for environmentally sustainable construction with high-energy targets. In order to reduce the consumption of fossil fuels significantly, the building should have a very low power consumption and enable a sustainable operation. A mostly compact form of the building and a highly insulated building envelope are a first prerequisite.

    The report investigates the technical feasibility of using the HTR modular reactor for steam supply to tertiary oil recovery, and for hydrogen recovery from the resulting petroleum gas. The report focusses on the design of the two main components, HTR modular reactor with a steam generator, and HTR modular reactor with a steam reformer, and on explaining the alternative system concepts feasible by varying the mode of combination of the two main components. Also, the design concept of a system for heat transport using nuclear long-distance energy (ADAM and EVE) is explained. The technical aspects of the required water treatment system and of the gas production unit for hydrogen recovery are discussed. (orig.).

    At the end of the 20th century, environmental destruction, climate change and forest die-back demonstrate that ecological issues, besides economic and technical ones, need to be considered in political and economic decision-making as criteria of equal rank. Complete budgeting, which takes into account all three aspects, by following up the entire life cycle of a product or span of a process can deal with this field of tension. Complete budgeting projects require budgets of individual substances, which are given here for various materials. All the same, this paper can only provide an overview; detailed, product-specific data are beyond its scope. (orig.)

    The overall objective of the project is to develop a general simulation environment for program systems used in reactor safety analysis. The simulation environment provides methods for graphical modeling and evaluation of results for the simulation models. The terms of graphical modeling and evaluation of results summarize computerized methods of pre- and postprocessing for the simulation models, which can assist the user in the execution of the simulation steps. The methods comprise CAD (''Computer Aided Design'') based input tools, interactive user interfaces for the execution of the simulation and the graphical representation and visualization of the simulation results. A particular focus was set on the requirements of the system code ATHLET. A CAD tool was developed that allows the specification of 3D geometry of the plant components and the discretization with a simulation grid. The system provides inter-faces to generate the input data of the codes and to export the data for the visualization software. The CAD system was applied for the modeling of a cooling circuit and reactor pressure vessel of a PWR. For the modeling of complex systems with many components, a general purpose graphical network editor was adapted and expanded. The editor is able to simulate networks with complex topology graphically by suitable building blocks. The network editor has been enhanced and adapted to the modeling of balance of plant and thermal fluid systems in ATHLET. For the visual display of the simulation results in the local context of the 3D geometry and the simulation grid, the open source program ParaView is applied, which is widely used for 3D visualization of field data, offering multiple options for displaying and ana-lyzing the data. New methods were developed, that allow the necessary conversion of the results of the reactor safety codes and the data of the CAD models. The trans-formed data may then be imported into ParaView and visualized. The application of 3D visualization shows advantages in transient analyses with very detailed discretization. This is especially true for the analysis of phenomena with strong local differences and the validation of multi-dimensional models.

    Due to its high efficiency and environmental friendliness, which is accounted for by its perfect adaptability to natural gas, the SOFC high-temperature fuel cell is especially well suited for decentralised power and heat supply systems. While the planar SOFC version is still largely in the development stage, with units of up to 10kW under study at various research institutions, the pipe version of Siemens Westinghouse has already reached a more advanced technical stage. A first 100 kW demonstration plant is being operated in the Netherlands by the Dutch/Danish EDB/ELSAM consortium. Despite certain starting difficulties the first 6,000 operating hours showed a very satisfactory behaviour. Net electrical efficiency reached 46%, a globally unrivalled achievement for a plant of this size. Using this concept as a starting point Siemens plans to put demonstration plants of up to 3 MW into operation in the course of the next three years. [German] Die Hochtemperatur-Brennstoffzelle SOFC ist aufgrund ihres hohen Wirkungsgrades und ihrer Umweltfreundlichkeit und durch den problemlosen Einsatzes von Erdgas besonders gut fuer die dezentrale Versorgung mit Strom und Waerme geeignet. Waehrend sich die planare SOFC noch weitgehend im Entwicklungsstadium von Einheiten bis 10 kW befindet und in Deutschland vorwiegend an Forschungseinrichtungen untersucht wird hat das Roehrenkonzept von Siemens Westinghouse bereits einen fortgeschrittenen technischen Stand erreicht. Eine erste 100 kW Demo-Anlage wird in den Niederlanden von dem hollaendisch/daenischen Konsortium EDB/ELSAM betrieben. Trotz einiger Startschwierigkeiten zeigten die ersten 6000 Betriebsstunden ein sehr zufriedenstellendes Verhalten. Mit 46% elektrischem Nettowirkungsgrad wurde ein fuer Anlagen dieser Groessenordnung bislang weltweit einmaliger Wert erreicht. Die Siemens AG plant, basierend auf diesem Konzept, in den naechsten drei Jahren Demonstrationsanlagen bis 1 MW in Betrieb zu nehmen. (orig.)

    Heating costs form the main part of the total energy cost of commercial sow operations. Within a commercial sow farm, most of the energy usage occurs in the farrowing compartment, because the temperature requirement is high for the suckling piglets. It was examined whether a reduction in temperature setting of 2C in combination with an adequate micro-climate for suckling piglets can contribute both to energy savings and improvement of lactating sow performance. In total, 96 sows were used in this study. The study was conducted in four naturally ventilated farrowing compartments (six sows per compartment) with a combination of indirect and direct air-inlet during November 1996 and May 1997. In the compartment with the standard temperature setting (control), the `set point for heating` and `set point for ventilation` were set at 21C and 23C, respectively, when all sows in the compartment had produced their litter. In the experimental compartment, both set points were reduced with 2C. A hoover with local heating was installed in each pen of the experimental compartments to provided the suckling piglets with an appropriate micro-climate. In total eight batches of sows were followed in the winter period. After each batch, the control and experimental treatments were switched between compartments. In each of the eight batches, a difference in room temperature was realised between the compartment with the standard and reduced temperature settings. The room temperature was on average 1.1C lower in the compartment with the reduced temperature setting. The reduction in room temperature had no effect on lactating sow and piglet performance. In conclusion it is possible to reduce the room temperature in naturally ventilated farrowing barns, where the air-inlet is direct and the optimum micro-climate of the suckling piglets can be guaranteed using a hoover. Energy savings in the compartments with reduced temperature settings mounted to DFI 3 per sow and year, without negative effects on lactating sow and piglet performance. The increased cost for electricity (DFl 3.50 per sow and year) can be avoided when using floor heating and letting the call light in the hoover burn for only a few days after farrowing. 5 refs.

    In the Federal Republic of Germany, the long-term discussion on an adequate differentiation of utilization and removal of wastes in incineration plants and other combustion plants has ended in dead-ends. Actually, wastes energetically are used in an incineration plant. Theoretically, in the jurisdiction and in the literature this possibility is denied. The general expectation that the actual change of the waste framework directive of the European Union points a way out of this dead-end threatens to be disappointed. The reason is the proposal of an energy efficiency criterion and the necessary calculation parameter for this. Both do not lead to a measurable result. Instead of this, different percentages are calculated as energy efficiency criterion. The solution of this dilemma may be the differentiation between the facts level and the legal consequence level for the differentiation decision. The statement whether the combustion of certain wastes in a combustion plant represents a utilization or not, is a fact question. On the legal consequence side, the possibility should be granted of modifying the legal consequences attached to the utilization. By it, the conflict between engineering science and jurisprudence only can be avoided.

    Materials and Methods: Twenty of the first 26 consecutive patients referred for potential UFE were enrolled in the study. Pre-interventional MRI was used to assess morphologic contraindication to UFE. The embolization procedures were performed from a unilateral femoral approach using 4F selective catheters in straight vessels, >2 mm in diameter, and micro-catheters in smaller and tortuous arteries. The endpoint of the 'flow guided' embolization was defined by reaching the angiography 'pruned tree' appearance and sluggish flow in the main stem of the uterine artery. Assessment of morphologic mid term success was done by MRI 10 days, 3 months, 6 months, 9 months and 1 year after UFE. The clinical mid term success was assessed by having questionaires completed for menstrual bleeding, retention of clinical (symptomatic) benefit and quality of life. Results: Technical success was 100%, with 8 minor (2 post-interventional collapses, 2 hematomas, 4 relevant post-embolizations syndromes, 1 spontaneous expulsion of a submucous myoma) and 3 major complications (1 hysterectomy because of vaginal bleeding for 5 weeks, 1 transient amenorrhea and 1 spontaneous expulsion of myoma with transient bleeding requiring admission). In 17 of 19 patients, MRI showed total fibroid devascularization throughout the entire follow-up. The average shrinkage of the dominant fibroid was 71.3% at one year. The menstrual bleeding record in the cohort group fell from an average of 501.6 before treatment to 76.2 points at one year. At the same time, the clinical symptoms significantly improved. The patient satisfaction with the applied therapy was >95% at 1 year. One patient with residual fibroid perfusion underwent a second procedure, which achieved complete devascularization and adequate clinical success at one year. The second patient with incomplete devascularization had a persistent clinical benefit. (orig.)

  12. Green house gas emissions in German agriculture. Sources and technical reduction capacities under special consideration of biogas; Treibhausgas-Emissionen in der deutschen Landwirtschaft. Herkunft und technische Minderungspotenziale unter besonderer Beruecksichtigung von Biogas

    Wegener, Jens-Karl

    This monograph is concerned with different aspects of green house gas (GHG) emissions in agriculture. The first part summarizes the total amount of GHG emissions and analyses them regarding their composition. A differentiation is made between the emissions which are already linked to agriculture (source group agriculture: ''digestion'', ''manure-management'' and ''agricultural soils'') within the ''National Report on GHG Emissions'' and those which can be counted primarily in addition to agriculture (''energy'' and ''land use and land use change''). Depending on which database is used, agriculture is participating in emitting green house gases with 6.3% or 11.1% of total German GHG emissions in 2004. This means that agriculture is an important polluter. The development of GHG emissions in agriculture compared to the year 1990 is -18.5% for the source group agriculture. This means that the source group has reduced more emissions than the average (-17.5%) over all domains published within the National Report. Regarding the sources ''energy'' and ''land use and land use change'' in addition emission reduction is -16.4% in the same period and thus worse than the average. Moreover, realized emission reductions are predominantly based on structural changes, less on systematical measures. This fact raises the question how agriculture can make a contribution to the reduction of GHG emissions in future particularly with regard to higher aims in climate politics. For this reason the second part of the monograph identifies capacities for the reduction of GHG emissions by using available agricultural biomass for energetic purposes. Due to the heterogeneity of biomass and the variety of its possible products, a lot of technical processes concerning the conversion of biomass into energy exist in practice. Since all of them have different emission factors the derivation of realistic reduction capacities is a nontrivial problem. This work restricts the problem by combining existing biomass with those technologies which provide largest benefit concerning the reduction of GHG emissions. Thereby it is possible to evaluate the maximum contribution of GHG reductions from biomass usage in agriculture in Germany, which aggregates up to 50,341 Gg CO{sub 2}-equivalent. This means that 78.3% of the emissions from the source group agriculture in 2004 could be compensated if biomass was used within those technologies which produce the largest benefit. In this regards the subsidy of energy crops in biogas plants based on the ''Erneuerbare Energien Gesetz'' (renewable energy law) in Germany should be reviewed because there they do not produce the largest benefit. Energy crops should be applied to replace solid fuels instead. Since in practice several biogas plants are already using energy crops as input material without having an option for alternatives, the question raises how this fact can be improved for the future regarding climate protection. Therefore the third part of this monograph analyses the possible emission reductions of different technologies for converting biogas into energy. Objects of investigation are existing technologies like block heat and power plants or direct gas feeding into public gas distribution system as well as future technologies like the application of biogas in different types of fuel cells. Although direct gas feeding has a better ratio concerning the conversion of primary to secondary energy the GHG reduction capacity is much less compared to technologies of cogeneration. The reason for this is that the production of electricity has much more effect on GHG emissions than the production of heat. This is to be seen when comparing the emission factors of certain reference systems used in this part like condensing boilers running with natural gas (253 gCO{sub 2}/kWhheat), gas steam power plants (432 gCO{sub 2}/kWhel) and the average emissions factor of German power production (653 gCO{sub 2}/kWhel). The more electricity is produced by a conversion technology based on biogas, the higher is its GHG reduction capacity. Direct gas feeding is not the most efficient way of using biogas in matters of climate protection considering that only 13% of the natural gas in Germany is used for electric purposes and considering that replacing natural gas by biogas means that the part of fossil fuels with lowest emissions is replaced. Direct gas feeding is not even then the most efficient way of using biogas if there is a consumer at the other end of the public gas distribution system who theoretically uses the injected biogas for running cogeneration systems. The conditioning of biogas in order to feed public distribution combined with additional heat source for running the fermenter of the biogas plant is worse for efficiency. Considering ecological standpoints local heat and power production next to the fermenter is the most efficient way of using biogas in matters of climate protection. This can only be improved by using more efficient systems like fuel cells instead of existing block heat and power plants. (orig.)

    Hydrothermal Carbonisation (HTC) is an innovative process to convert biogenic residual materials from municipalities into high-quality biogenic solid fuels (charcoal). However, this entails increasing fuel costs. Especially high capital costs and a lower capacity factor of innovative processes as well as the pelletising of the charcoal are the main cost drivers. Hence an on-site utilisation of the charcoal without pelletising, e.g. for heat generation, has a high cost reduction potential. Due to the higher capital costs of solid fuel boilers and fuel storage compared to oil and gas boilers, a high degree of capacity utilisation should be pursued to reduce the fixed cost share and, by this means, lower the levelised costs of heat. Currently, the Hydrothermal Carbonisation conversion process is expensive. Therefore, using the charcoal for heat production is not competitive compared to other fossil or biofuels. The high development and cost reduction potential of this innovative process may have a positive economic impact on future utilisation.

    Due to the planned phase-out of nuclear energy and the liberalisation of the energy markets decentralised energy supply system with small-scale or micro-cogeneration plants will become more important in the future. The economic success of these plants hinges on the costs that self-producers are able to avoid and on the revenue they make through feed-in compensation. The decisive success factor is a high electricity requirement of the producer himself, which he does not always have however. A conceivable option for making the use of micro cogeneration plants economically attractive also for operators without a sufficient electricity requirement of their own is to bundle unused production capacities in virtual power plants to make them available to power suppliers as a reserve in case of power plant failures or deviations from load forecasts. In this way a new potential for value creation could be tapped for micro cogeneration plants. This should lead to a more widespread use of this technology, which is distinguished by low CO{sub 2} emissions and avoidance of primary energy use.

    Since the implementation of the EEG in Germany the biogas production becomes an independent branch of industry in the agriculture. At this time more than 90 percent of the biogas plants work with co-generation plant for heat and power with a thermal engine efficiencies of more than 50 percent. Because of the location in the rural area heat costumers with a continuous demand of heat over the whole year are rare. This research had a closer look how to use the heat of biogas production efficiently and also generating profit. The aim of the study was to use heat over the whole year, a profitable heat concept without counting the KWK-bonus and an added value on the farm. During the study the following concepts were analyzed: asparagus production using soil heating, drying equipment for different products, the production of fish in aquaculture, the poultry production and the heated production of tomatoes. The results showed different concepts using heat of biogas plants as efficient for farmers. However with only one concept the aims - to use the heat over the whole year, generating a profitable heat concept without counting the KWK-bonus, add an value on the farm - mostly can not be achieved. The combination of different heat concepts is necessary. In this analysis the poultry production in combination with the dryer can be considered as the most efficient concept. Bearing in mind the benefit which can be generated with a heat concept as well as the higher income and the higher technical efficiency of biogas plants operators should implement an individual concept for their heat.

    This special section of Journal of Micromechanics and Microengineering features papers selected from the 10th International Workshop on Micro and Nanotechnology for Power Generation and Energy Conversion Applications (PowerMEMS 2010). The workshop was organized in Leuven, Belgium from 30 November to 3 December 2010 by Katholieke Universiteit Leuven and the imec/Holst Centre. This was a special PowerMEMS Workshop, for several reasons. First of all, we celebrated the 10th anniversary of the workshop: the first PowerMEMS meeting was organized in Sendai, Japan in 2000. None of the organizers or participants of this first meeting could have predicted the impact of the workshop over the next decade. The second reason was that, for the first time, the conference organization spanned two countries: Belgium and the Netherlands. Thanks to the advances in information technology, teams from Katholieke Universiteit Leuven (Belgium) and the imec/Holst Centre in Eindhoven (the Netherlands) have been able to work together seamlessly as one team. The objective of the PowerMEMS Workshop is to stimulate innovation in micro and nanotechnology for power generation and energy conversion applications. Its scope ranges from integrated microelectromechanical systems (MEMS) for power generation, dissipation, harvesting, and management, to novel nanostructures and materials for energy-related applications. True to the objective of the PowerMEMSWorkshop, the 2010 technical program covered a broad range of energy related research, ranging from the nanometer to the millimeter scale, discussed in 5 invited and 52 oral presentations, and 112 posters. This special section includes 14 papers covering vibration energy harvesters, thermal applications and micro power systems. Finally, we wish to express sincere appreciation to the members of the International Steering Committee, the Technical Program Committee and last but not least the Local Organizing Committee.

    German universities of applied sciences are characterized by applied specialty setting in-tegrated deeply into the transformation and development of regional industry and flexible choice policy of students’ specialties. Taking Deggendorf Institute of Technology as an example, the prac-tices of applied specialty setting and students ’ specialty choices of German universities of applied sciences are focused. The advantages of the universities in specialty setting and the students’ spe-cialty choices are discussed. The cultivation orientation of applied professionals can be realized by three ways: establishing a talent demand forecasting and specialty early preditting system;formulating a dynamic specialty evaluation system, and promoting the construction of characteristic specialty and specialty groups that serve diversified sectors of the industry; constructing a distin-guished specialty system catered to the regional industrial development. Secondly, the innovation of the training mode of applied professionals can be promoted by two ways:formulating and implemen-ting the directors or board system participated by industry and enterprises, evaluation system of spe-cialty setting, and performance evaluation system of professionals training, strengthening industry and education integrated specialty setting. Thirdly, specialty settings can be optimized by establishing students’ specialty choice-based specialty competition mechanism.%与区域产业转型发展深度融合的应用性专业设置以及灵活的学生专业选择政策,是德国应用技术大学的显著特征。以德国代根多夫应用技术大学为例,可以得到相关借鉴与启示:第一,建立人才需求预测和专业预警机制、专业动态评估制度,推进服务产业的特色专业和专业群建设,构建契合产业发展、根植当地、特色鲜明的专业体系,以实现应用型人才培养定位。第二,制定和实施行业企业和用人单位参与的理事会(董事会)制度、专业设置评议制度、人才培养绩效评价制度等,加强产教融合的专业设置,推动应用型人才培养模式创新。第三,建立学生专业选择下的专业竞争机制,促进高校优化专业设置,提升人才培养质量。

    The previous technologies for the development of the decentralized combined heat and power generation are based on various concepts with different ripeness. Gasification is regarded as an energetically promising technology, which is not yet marketable. Under this aspect, the author of the contribution under consideration reports on an economic evaluation of the decentralized power and heat production by gasification of biogenic solid fuels and on a comparison with existing alternative technologies of combustion. In particular, the author examines the following central issues: (a) Which technologies of gasification can be regarded as promising with respect to a decentralized application?; (b) How are the technologies of gasification to be evaluated with respect to the alternative technologies of combustion from technical and economic view? For the comparative view of these different techniques, an electrical output of 500 W is specified as a uniform characteristic value of performance according to the decentralized gasification and combustion.

    This project was dedicated to the assessment of the fueling quality of commercial domestic and agricultural furnaces. Emphasis was placed on the assessment of emissions. Certain emission reduction measures were developed, the present state of knowledge of the combustion of biogenic solid fuels was summarized, and a market analysis of furnace supplies was prepared. The three parts of this research report deal with the thermal utilization of biogenic solid fuels - literature study and market analysis of the present state of biogenic solid fuel combustion and systems engineering; the assessment of the emission behavior of solid-fuel furnaces - bench-scale stove and central heating furnace measurements; and the development of a combustion air control system which reduces the emissions of hand-fed wood-fired furnaces - development and testing of a combustion aircontrol system with flue gas sensor and fuzzy logic controller.

    The report investigates the use of HTR modular reactors for tertiary oil recovery in the Emsland oil fields of Ruehlermoor and Georgsdorf with a view to the economic aspects of such a project. The reference plant used for the study is a HTR-2 modular reactor for combined steam and hydrogen generation. In addition, some plant variants are considered (HTR-2 and HTR-3 modular systems) also for steam generation only, in this case providing for the plants' higher steam output to be fed to the oil field, or to be used otherwise without additional cost (e.g. for electricity generation). As the Emsland oil fields are sites where the conditions of application of HTR modular systems are relatively unfavourable, the study also covers an assessment of the economic potentials of larger HTR-4 modular systems and their application at more favourable (foreign) oil fields.

    The R+D-project is subdivided into two subjects: 1. optimisation of propulsion system. Optimal steering subject to the operating levels. This was carried out by means of route profiles and variations of the gearing system depending on the load, the power of the engine and given speed limits. Savings in fuel: 2.7 l/100 km (6.8%). Amortisation of costs in 4.3 years. Other problematic areas exist with the general deployment on all routes without further programming requirements, automatic adjustment of propulsion parameters and the compatibility of the system and its ability to communicate. 2. Reduction of sound emission. Survey of sound emission at busses made of synthetic material. Numerous sound measurings and their analyses in order to realise sound causing phenomena and measures and constructive developments for minimizing the sound emissions resulting thereof.

    Project 3611R0801503 of the BMUB/BfS was focused on coordination and implementation of generic technical and organisational activities for assessments of nuclear safety and effectiveness of regulatory systems in foreign countries (with focus to Eastern Europe and in INSC partner countries). To comply with the BMUB objectives and the GRS strategy, the tasks were structured taking into account the specificity of countries and nuclear design series whereas the technical knowledge and results of the analyses were provided to meet the requirements. This final documentation on the project describes the results of the activities from 04/01/2011 through 09/31/2014 on working packages ''Programme Coordination'', ''Project Management'', ''Networks and On-Site Assistance'', ''Project Documentation'', ''Knowledge Management'', ''Design Series Specific Activities'', ''Multilateral Activities'', ''Country Specific Activities'', ''International Institutions'', ''EU Panels'', ''G8 and EBRD Funds'' and ''Network Activities''. The project contributed significantly to a systematic extension and deepening of knowledge in GRS. Also, international cooperation with selected regulators and their TSOs as well as with the IAEA, the EU and representatives of multilateral bodies was intensified. As intended, this allowed to extend the information and knowledge basis for nuclear safety. The know-how gain for GRS is to be rated as high. This is true for the work in international bodies, but also for the creation, further development and usage of national and international information, knowledge and cooperation platforms. By the insights gained from the project, GRS completes and consolidates its knowledge and tools available. The status achieved in the knowledge management development and respective platforms can be estimated as exemplary.

    On 1 January 2012 I will be assuming the position of Editor-in-Chief of the journal Semiconductor Science and Technology (SST). I am flattered by the confidence expressed in my ability to carry out this challenging job and I will try hard to justify this confidence. The previous Editor-in-Chief, Laurens Molenkamp, University of Würzburg, Germany, has worked tirelessly for the last ten years and has done an excellent job for the journal. Everyone at the journal is profoundly grateful for his leadership and for his achievements In 2012 several new members will join the Editorial Board: Professor Deli Wang (University of California, San Diego) with considerable expertise in semiconductor nanowires, Professor Saskia Fischer (Humboldt University, Berlin, Germany) with a background in semiconductor quantum devices, and Professor Erwin Kessels (Eindhoven University of Technology, Netherlands) with extensive experience in plasma processing of thin films and gate oxides. In particular, I want to express my gratitude to Professor Israel Bar-Joseph (Weizmann Institute of Science, Israel) and Professor Maria Tamargo (The City College of New York, USA), who will leave next year and who have vigorously served the Editorial Board for years. The journal has recently introduced a fast-track option for manuscripts. This option is a high-quality, high-profile outlet for new and important research across all areas of semiconductor research. Authors can expect to receive referee reports in less than 20 days from submission. Once accepted, you can expect the articles to be online within two or three weeks from acceptance and to be published in print in less than a month. Furthermore, all fast-track communications published in 2011 will be free to read for ten years. More detailed information on fast-track publication can be found on the following webpage: http://iopscience.iop.org/0268-1242/page/Fast track communications It is encouraging to see that since the journal introduced pre

    In this final report on the research project ''Energy-dispersive study of the interaction of fast neutrons with matter, especially materials for fusion and materials from fission reactors the status reached after three years promotion is described. The aim of this project is the construction and first usage of a very complex time-of-flight system for the study of the interaction of fast neutrons with construction materials for fusion and fission reactors as well as with long-lived radioisotopes. Furthermore astrophysically relevant experiments on problems of the element synthesis shall be performed. The whole project is devided into two sections: 1. Development, construction and test of a pulsed photoneutron source at the ELBE accelerator of the FZ Rossendorf, 2. Application of the photoneutron sources for measurements of cross sections induced by fast, energy-selected neutrons.

    Wedge-shape joints are a revolution in large-diameter pipe connection. Fitting is simplified considerably as compared to conventional cylindrical joints. Reproducible high-quality connections are achieved at only a fraction of the time formerly required. Assembly follows clear and simple rules. Anybody who can assemble a flange will be able to cope with the tightening system of the wedge-shaped joint.

    Two new deposition systems were realized enabling the entire and respectively, large area deposition of a-Si:H based solar cells using the so called 'hot-wire' (HW) CVD. The deposition conditions for appropriate n- and p-doped a-Si:H and {mu}c-Si:H layers have been developed. For the first time in the world a-Si:H based pin solar cells were entirely deposited by the HWCVD method. A maximum initial conversion efficiency of {eta}{sub initial}=8.9% was obtained. After the development of a suitable p/n-tunnel/recombination junction pin-pin tandem structures with a-Si:H absorbers could be entirely fabricated by the HWCVD for the first time in the world, too. A conversion efficiency of {eta}=7% was measured for the tandem cell, after some structural degradation took place. In general, the stability of the HWCVD solar cells is not satisfactory, what could be attributed to a structural instability of the HWCVD-p-layers. For the first time we have deposited nip solar cells on stainless steel substrates entirely by HWCVD ({eta}{sub initial}>6%). The incorporation of {mu}c-Si:H absorber layers by HWCVD or ECWR-PECVD into pin solar cells was not successfull until now. Large area deposition of a-Si:H films has been performed in a simple vacuum vessel. Under consideration of appropriate filament and gas supply geometry as well as simulation calculations a good electronic quality and a film thickness uniformity of {delta}d={+-}2.5% of the material was obtained. i-layers for small area solar cells on an area of 20 x 20 cm{sup 2} have been deposited which could be completed to solar cells with very uniform conversion efficiencies of {eta}{sub initial} = 6,1{+-}0.2%. This result represents a proof of concept for the large area deposition of a-Si:H based solar cells using the HWCVD. Also for the first time the HWCVD was used for the deposition of emitter layers on c-Si-wafers to realize hetero solar cells. Hetero solar cells with amorphous, microcrystalline and epitaxial n- and p-type emitters have been fabricated. After a very short development time conversion efficiencies have been obtained ({eta}{sub max} = 15.2%) which are reported for PECVD emitters. (orig.) [German] Zwei neue Anlagen zur vollstaendigen bzw. grossflaechigen Abscheidung von a-Si:H basierenden Solarzellen mit der sog. 'Hot-Wire (HW)' CVD wurden aufgebaut. Die Abscheidebedingungen fuer geeignete n- und p-dotierte a-Si:H- bzw. {mu}c-Si:H-Schichten wurden ermittelt. Weltweit wurde erstmals eine a-Si:H-pin-Zelle vollstaendig mit der HWCVD-Methode hergestellt, ein Anfangswirkungsgrad von {eta}{sub initial} = 8,9% wurde erreicht. Nach Entwicklung eines p/n-Tunnel- bzw. Rekombinationsueberganges ist es weltweit ebenfalls erstmals gelungen, pin-pin-Tandemstrukturen mit a-Si:H-Absorbern vollstaendig mit der HWCVD-Methode abzuscheiden. Nach Teilalterung wurden noch Wirkungsgrade von {eta}{approx}7% ermittelt. Generell ist die Stabilitaet der all-HWCVD-Zellen noch unbedriedigend, was auf strukturell instabile p-Schichten zurueckgefuehrt werden konnte. Erste nip-Solarzellen auf Edelstahlsubstraten wurden ebenfalls vollstaendig mit der HWCVD praepariert ({eta}{sub initial}>6%). Der Einbau von {mu}c-Si:H-Absorberschichten die mit HWCVD bzw. ECWR-PECVD hergestellt wurden, in pin-Solarzellen war bisher wenig erfolgreich. In einer Anlage zur grossflaechigen HWCVD-Abscheidung wurden a-Si:H-Schichten mit guter Qualitaet und einer Schichtdickenuniformitaet von {delta}d = {+-}2,5% hergestellt. Fuer sog. 'Huepfzellen', nur die i-Schicht wurde in der Anlage abgeschieden, wurden auch sehr uniforme Anfangswirkungsgrade {eta}{sub initial}=6,1{+-}0,2% fuer kleinflaechige Zellen auf einer Flaeche von 20 x 20 cm{sup 2} erreicht. Diese Ergebnisse koennen als 'proof of concept' fuer die grossflaechige HWCVD-Abscheidung fuer a-Si:H-basierende Solarzellen betrachtet werden. Erstmals wurde die HWCVD zur Abscheidung von Emitter-Schichten fuer Hetero-Solarzellen auf c-Si-Wafer-Basis eingesetzt. Es wurden Hetero-Solarzellen mit amorphen, mikrokristallinen und epitaktischen n- und p-Typ-Emittern hergestellt. Die Wirkungsgrade erreichten auf Anhieb Werte ({eta}{sub max}=15,2%), wie sie nach laengerer Entwicklungszeit fuer PECVD-Emitter berichtet wurden. (orig.)
