    While the free-living fauna of the Wadden Sea has received much interest, little is known on the distribution and effects of parasites in the Wadden Sea food web. However, recent studies on this special type of trophic interaction indicate a high diversity of parasites in the Wadden Sea and suggest a multitude of effects on the hosts. This also includes effects on specific predator-prey relationships and the general structure of the food web. Focussing on molluscs, a major group in the Wadden Sea in terms of biomass and abundance and an important link between primary producers and predators, we review existing studies and exemplify the ecological role of parasites in the Wadden Sea food web. First, we give a brief inventory of parasites occurring in the Wadden Sea, ranging from microparasites (e.g. protozoa, bacteria) to macroparasites (e.g. helminths, parasitic copepods) and discuss the effects of spatial scale on heterogeneities in infection levels. We then demonstrate how parasites can affect host population dynamics by acting as a strong mortality factor, causing mollusc mass mortalities. In addition, we will exemplify how parasites can mediate the interaction strength of predator-prey relationships and affect the topological structure of the Wadden Sea food web as a whole. Finally, we highlight some ongoing changes regarding parasitism in the Wadden Sea in the course of global change (e.g. species introduction, climate change) and identify important future research questions to entangle the role of parasites in the Wadden Sea food web.

  19. Automated Waterline Detection in the Wadden Sea Using High-Resolution TerraSAR-X Images

    Directory of Open Access Journals (Sweden)

    Stefan Wiehle

    2015-01-01

    Full Text Available We present an algorithm for automatic detection of the land-water-line from TerraSAR-X images acquired over the Wadden Sea. In this coastal region of the southeastern North Sea, a strip of up to 20 km of seabed falls dry during low tide, revealing mudflats and tidal creeks. The tidal currents transport sediments and can change the coastal shape with erosion rates of several meters per month. This rate can be strongly increased by storm surges which also cause flooding of usually dry areas. Due to the high number of ships traveling through the Wadden Sea to the largest ports of Germany, frequent monitoring of the bathymetry is also an important task for maritime security. For such an extended area and the required short intervals of a few months, only remote sensing methods can perform this task efficiently. Automating the waterline detection in weather-independent radar images provides a fast and reliable way to spot changes in the coastal topography. The presented algorithm first performs smoothing, brightness thresholding, and edge detection. In the second step, edge drawing and flood filling are iteratively performed to determine optimal thresholds for the edge drawing. In the last step, small misdetections are removed.

  2. Morphodynamics of Wadden Sea Areas – Field Measurements and Modeling

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available The Wadden Sea areas of the German North Sea coast are affected by intense morphodynamics. Especially in the mouths of the estuaries sedimentation and erosion occur on different temporal and spatial scales and therefore challenge the decision-makers. To satisfy the requirements, which modern maritime traffic demands, a sustainable concept for sediment management has to be developed to grant an economic and ecologic balanced system. To evaluate different actions and their effects, e.g. by means of numerical models, an improved knowledge of morphodynamic processes on tidal flats is required. The Institute of River and Coastal Engineering at the Hamburg University of Technology runs detailed measurements to collect hydrodynamic and morphodynamic data of tidal flats in the estuary Elbe, that is the approach to the port of Hamburg. Water levels, flow and wave parameters and concentrations of suspended sediments are recorded in high resolution. Furthermore, the bathymetry is determined in frequent intervals with a multi-beam echo sounder.

    2015-06-01

    In October 2010, specimens of Oithona were taken from the List Tidal Basin in the northern Wadden Sea (North Sea) for a biogeographic study on Oithona similis. These specimens could not be assigned to O. similis or any of the other Oithona species known from the North Sea genetically. These specimens were identified as Oithona davisae Ferrari and Orsi 1984, a Northwest Pacific species, known as an invasive species from the Black Sea and the northwestern Mediterranean Sea. Recent sampling provided evidence that O. davisae is still present in the northern Wadden Sea and may thus now be a permanent plankton species.

    The project 'Thematische Kartierung und Sensitivitaetsraster des Deutschen Wattenmeeres' includes a methodically uniform inventory of the whole German Wadden Sea performed between 1987 and 1992. The inventory is based on quantitative and descriptive data and contains a documentation of temporary aspects. The project acts as a nucleus for the development of the Wadden Sea information System WATiS. The project forms the basis for direct applications for nature protection and oil-spill measures; in addition, a procedure to deliminate representative areals is demonstrated which can be used for example in the 'Trilateral Monitoring and Assessment Program' for the Wadden Sea. With the coupling to the computerbased maritime environmental management system 'REMUS' (presently developed) the prerequisites are generated to combine logistical, technical and scientific techniques for provision and combat measures.

    2015-04-01

    A high-resolution baroclinic three-dimensional numerical model for the entire Wadden Sea of the German Bight in the southern North Sea is first validated against field data for surface elevation, current velocity, temperature and salinity at selected stations and then used to calculate fluxes of volume, heat and salt inside the Wadden Sea and the exchange between the Wadden Sea and the adjacent North Sea through the major tidal inlets. The General Estuarine Transport Model (GETM) is simulating the reference years 2009-2011. The numerical grid has a resolution of 200x200m and 30 adaptive vertical layers. It is the final stage of a multi-nested setup, starting from the North Atlantic. The atmospheric forcing is taken from the operational forecast of the German Weather Service. Additionally, the freshwater discharge of 23 local rivers and creeks are included. For validation, we use observations from a ship of opportunity measuring sea surface properties, tidal gauge stations, high frequency of salinity and volume transport estimates for the Mardiep and Spiekeroog inlet. Finally, the estuarine overturning circulation in three tidal gulleys is quantified. Regional differences between the gullies are assessed and drivers of the estuarine circulation are identified. Moreover, we will give a consistent estimate of the tidal prisms for all tidal inlets in the entire Wadden Sea.

    2017-09-01

    Long-term field observations of nitrogen [N] and phosphorus [P] concentrations were used to construct nutrient budgets for the western Dutch Wadden Sea between 1976 and 2012. Nutrients come into the western Dutch Wadden Sea via river runoff, through exchange with the coastal zone of the North Sea, neighbouring tidal basins and through atmospheric deposition (for N). The highest concentrations in phosphorus and nitrogen were observed in the mid-1980s. Improved phosphorus removal at waste water treatment plants, management of fertilization in agriculture and removal of phosphates from detergents led to reduced riverine nutrient inputs and, consequently, reduced nutrient concentrations in the Wadden Sea. The budgets suggest that the period of the initial net import of phosphorus and nitrogen switched to a net export in 1981 for nitrogen and in 1992 for phosphorus. Such different behaviour in nutrient budgets during the rise and fall of external nutrient concentrations may be the result of different sediment-water exchange dynamics for P and N. It is hypothesized that during the period of increasing eutrophication (1976-1981) P, and to a lesser degree N, were stored in sediments as organic and inorganic nutrients. In the following period (1981-1992) external nutrient concentrations (especially in the North Sea) decreased, but P concentrations in the Wadden Sea remained high due to prolonged sediment release, whilst denitrification removed substantial amounts of N. From 1992 onwards, P and N budgets were closed by net loss, most probably because P stores were then depleted and denitrification continued. Under the present conditions (lower rates of sediment import and depleted P stores), nutrient concentrations in this area are expected to be more strongly influenced by wind-driven exchange with the North Sea and precipitation-driven discharge from Lake IJssel. This implies that the consequences of climate change will be more important, than during the 1970s and 1980s.

    Long-term patterns in fish phenology in the western Dutch Wadden Sea were studied using a 53 year (1960-2013) high resolution time series of daily kom-fyke catches in spring and autumn. Trends in first appearance, last occurrence and peak abundance were analysed for the most common species in relation to mode of life (pelagic, demersal, benthopelagic) and biogeographic guild (northern or southern distribution). Climate change in the western Wadden Sea involved an increase in water temperature from 1980 onwards. The main pattern in first day of occurrence, peak occurrence and last day of occurrence was similar: a positive trend over time and a correlation with spring and summer water temperature. This is counterintuitive; with increasing temperature, an advanced immigration of fish species would be expected. An explanation might be that water temperatures have increased offshore as well and hence fish remain longer there, delaying their immigration to the Wadden Sea. The main trend towards later date of peak occurrence and last day of occurrence was in line with our expectations: a forward shift in immigration into the Wadden Sea implies also that peak abundance is delayed. As a consequence of the increased water temperature, autumn water temperature remains favourable longer than before. For most of the species present, the Wadden Sea is not near the edge of their distributional range. The most striking phenological shifts occurred in those individual species for which the Wadden Sea is near the southern or northern edge of their distribution.

  7. Seasonal Variation of Harbor Seal's Diet from the Wadden Sea in Relation to Prey Availability.

    Directory of Open Access Journals (Sweden)

    Camille de la Vega

    Full Text Available The Wadden Sea has an important role for marine mammals in terms of resting, nursing and foraging. Harbor seal is the most abundant marine mammal species in this area. The use of the food resources of the Wadden Sea by seals is not clear, and previous studies showed that this species can travel kilometers away from their haul-outs to forage in the North Sea. In this study, we analyzed the stable isotopes of vibrissae from 23 dead harbor seals found on the island of Sylt to investigate their diet. The predator´s carbon and nitrogen isotope compositions were compared to the compositions of different potential prey items from the Sylt-Rømø Bight and from the North Sea in order to study seasonal pattern in the diet and in the foraging location. In parallel, seasonal variation of abundance and biomass of the potential prey items from the Sylt-Rømø Bight were studied and compare to their contribution to the seal´s diet. The results revealed a change in the seal´s diet from pelagic sources in spring to a benthic based diet in summer, and an increasing use of the North Sea resources in fall and winter in accordance with the seasonal variation of the availability of prey in the Sylt-Rømø Bight.

    2013-09-01

    The governance of the Wadden Sea has to contend with a complex interplay of social and ecological systems. Social systems tend to be characterized by pluralism of - often conflicting - norms and values, and ecological systems are characterized by high complexity and natural and human-induced variability, leading to unpredictable and nonlinear behavior. This highly volatile situation challenges traditional forms of management as well as traditional ways of organizing knowledge for decision-making processes. Ecosystem-based management approaches have been developed to find more effective, holistic, and evidence-based strategies to deal with the challenges of complex socio-ecological systems. They also require another way of dealing with (scientific) knowledge, the way it is produced and applied. In this paper, from the perspective of ecosystem-based management, we define the specific principles that apply to the way knowledge is mobilized and applied within decision-making processes. We illuminate these principles by examining three empirical cases of ecosystem-based management within, or related to, the Wadden Sea area. Finally, we reflect upon our findings and elaborate on the extent to which our theoretical framework is capable of describing and assessing the interaction between knowledge and decision making within ecosystem-based management approaches.

    The determination of food web structures using Ecological Network Analysis (ENA) is a helpful tool to get insight into complex ecosystem processes. The intertidal area of the Wadden Sea is structured into diverse habitat types which differ in their ecological functioning. In the present study, six different intertidal habitats (i.e. cockle field, razor clam field, mud flat, mussel bank, sand flat and seagrass meadow) were analyzed using ENA to determine similarities and characteristic differences in the food web structure of the systems. All six systems were well balanced between their degree of organization and their robustness. However, they differed in their detailed features. The cockle field and the mussel bank exhibited a strong dependency on external imports. The razor clam field appeared to be a rather small system with low energy transfer. In the mud flat microphytobenthos was used as a main food source and the system appeared to be sensitive to perturbations. Bird predation was the most pronounced in the sand flat and the seagrass meadow and led to an increase in energy transfer and parallel trophic cycles in these habitats. Habitat diversity appears to be an important trait for the Wadden Sea as each subsystem seems to have a specific role in the overall functioning of the entire ecosystem.

    The Dutch Wadden Sea (DWS), situated between continental Europe and the Dutch Wadden Islands, is a semi enclosed basin connected to the North Sea by a series of tidal inlets and composed mainly of tidal flats and sea gullies. The DWS is of high ecological importance due to its biodiversity and has been declared a World Heritage site by UNESCO. It is a dynamic area subject to regional relative sea level rise due to global sea level rise, postglacial rebound and gas exploitation. For intertidal areas to continue to serve as feeding ground for migratory birds, a net import of sediment is required. Observations are crucial but provide only scarce information in space and time. Hence, to estimate the net influx of suspended sediment into the DWS, realistic high resolution three-dimensional numerical simulations have been carried out using the General Estuarine Transport Model (GETM). The hydrodynamics are mainly governed by the tides, the fresh water discharge from several sluices into the DWS and wind variability. It is expected that the transport of suspended particulate matter (SPM) is governed by the same factors, too, in combination with sediment sink and source terms. For validation, the results are compared against different observational data sets, such as tidal gauges, temperature and salinity at a fixed station, and the volumetric flux rate through one of the inlets obtained from an acoustic Doppler current profiler (ADCP) attached to a ferry. SPM transport is modeled for four different sediment classes each of which is defined by the critical shear stress and the settling velocity. Results show a clear net import of SPM through one of the inlets, which is in agreement with the observations. First estimates of the total sediment fluxes through the different inlets are presented together with an analysis on their variability and sensibility to the external forcing. Of particular importance is the net export of SPM during storms as well as the role of storms on

  9. Organochlorines in benthic invertebrates and sediments from the Dutch Wadden Sea; identification of individual PCB components

    Duinker, J. C.; Hillebrand, M. T. J.; Boon, J. P.

    Concentrations of organochlorines were determined in Macoma balthica, Arenicola marina, Crangon crangon and sediments from the Dutch Wadden Sea. Maximum concentrations of (total) PCB, γ-HCH and dieldrin were found in the western part; a pronounced maximum of HCB was found in the western part. Concentrations of PCB, p,p'-DDD and p,p'-DDE in sediment were correlated with the percentage of particles metabolism, were lower in Crangon. The patterns of pentachloro- and higher chlorinated biphenyls were equal in Macoma, Arenicola and sediments. Since these components are not found in solution, they must be taken up from sediment and food. The results are in agreement with partitioning between body lipids and water as the dominant mechanism determining concentrations of persistent lipophilic contaminants in the animals. Partitioning with the ambient water may also determine the concentrations in the sediment.

    The Wadden Sea is an extensive wetland area, recognized as UNESCO world heritage site of international importance. Since the mid-1990s, the invasive Pacific oyster Crassostrea gigas (Thunberg 1793) population in the area has grown exponentially, having a distinct impact on the ecosystem. The recent spread of the emerging oyster pathogen Ostreid herpesvirus OsHV-1 μVar worldwide and specifically in the oyster culture areas in the south of the Netherlands raised the question whether the virus may also be present in the Wadden Sea. In the summer of 2012 juvenile Pacific oysters were collected from five locations in the Dutch Wadden Sea. The virus was shown to be present in three of the five locations by real-time PCR and sequencing. It was concluded that OsHV-1 μVar has settled itself in Pacific oyster reefs in the Wadden Sea. These results and the recent discoveries of OsHV-1 microvariants in Australia and Korea indicate that OsHV-1 μVar and related variants might be more widespread than can be deduced from current literature. In particular in regions with no commercial oyster culture, similar to the Wadden Sea, the virus may go undetected as wild beds with mixed age classes hamper the detection of mortality among juvenile oysters. © 2015 John Wiley & Sons Ltd.

    2018-03-01

    Observations of underway velocity profiles during complete spring and neap tidal cycles were used to determine whether the spatial structures of tidal and subtidal flows at a tidal inlet in a multiple-inlet embayment are consistent with those observed at single-inlet embayments. Measurements were obtained at the Otzumer Balje, one of the multiple inlets among the East Frisian Islands of the Wadden Sea. The 1.5 km-wide inlet displayed a bathymetric profile consisting of a channel ∼15 m deep flanked by tide observations spanned 36 h in the period May 11-12, 2011, while spring tide measurements exceeded 48 h from May 17 to May 19, 2011. Analysis of observations indicate that frictional effects from bathymetry molded tidal flows. Spatial distributions of semidiurnal tidal current amplitude and phase conform to those predicted by an analytical model for a basin with one inlet. Maximum semidiurnal flows appear at the surface in the channel, furthest away from bottom friction effects. Therefore, Otzumer Balje displays tidal hydrodynamics that are independent of the other inlets of the embayment. Subtidal exchange flows are laterally sheared, with residual inflow in the channel combined with outflow over shoals. The spatial distribution of these residual flows follow theoretical expectations of tidally driven flows interacting with bathymetry. Such distribution is similar to the tidal residual circulation at other inlets with only one communication to the ocean, suggesting that at subtidal scales the Otzumer Balje responds to tidal forcing independently of the other inlets.

    The Wadden Sea undergoes large seasonal changes in species abundance and biomass comprising its complex food web. This study examined four carbon food web models of the Sylt-Rømø Bight, one for each season. Each flow model consisted of 66 compartments depicting the respective biomass and energy budget of each ecosystem component and the flows between them. Ecological network analysis (ENA), a set of algorithms to evaluate the functioning of ecological networks, was used to assess the seasonal variability in the system properties of the Sylt-Rømø Bight food webs. We used an uncertainty analysis to quantitatively evaluate the significance of inter-seasonal differences. Clear seasonal variation was observed in most of the whole system indicators such as the flow diversity, the effective link density and the relative redundancy which varied by 12.8%, 17.3% and 10.3% respectively between the highest in summer and the lowest during fall and winter, whereas the relevant ascendency ratio was the highest in winter during the least active months. Other indices such as the average mutual information index, which fluctuated between 1.73 in fall and 1.79 in spring, showed no significant variation between seasons. Results from ENA have great potential for ecosystem management, as it provides a holistic assessment of the functioning of ecosystems.

  17. Disease prevalence in flounder (Platichthys flesus) from the Dutch Wadden Sea as indicator of environmental quality: A summary of 1988-2005 surveys

    2013-09-01

    In 1988, epizootics of ulcer disease in the flatfish flounder in the Dutch Wadden Sea were reported near freshwater drainage sluices of IJsselmeer Lake, locally affecting up to 38.9% of fish. Other diseases such as fin rot and lymphocystis were less frequent, but followed a similar pattern. Results of follow-up surveys in the Wadden Sea in 1994-2005 confirm previous findings and also show significantly elevated ulcer prevalences at other smaller drainage works. The most likely stress factors that contributed to the development of the epizootics at these sites include osmotic stress, adverse water quality conditions including chemical contaminants, nutritional deficiencies, and obstruction to fish migration. It was shown that discharges of IJsselmeer Lake freshwater in 1988-96 had a wide effect on the prevalence and distribution of ulcers and lymphocystis in the western Wadden Sea. A general reduction in disease prevalence in flounder in the entire Dutch Wadden Sea was observed during 1988-2005, which was most likely due to a general improvement in water quality and locally improved habitat conditions for flounder near drainage sluices. Ulcer prevalences outside the two IJsselmeer Lake sluices (Den Oever and Kornwerderzand) declined in this period from approximately 30% to 10% for medium-sized fish. Other skin diseases have also displayed a downward trend at both sites in recent years, with prevalences falling sharply to below 1%. Elsewhere in the Wadden Sea and the Ems-Dollard estuary, disease prevalences have declined towards natural background levels (< 1%). It is concluded that skin diseases, especially ulcers, are useful indicators of environmental quality in the Wadden Sea.

  18. Advanced Water Quality Modelling in Marine Systems: Application to the Wadden Sea, the Netherlands

    2006-12-01

    There is an increasing demand for knowledge and models that arise from water management in relation to water quality, sediment quality (ecology) and sediment accumulation (ecomorphology). Recently, models for sediment diagenesis and erosion developed or incorporated by Delft Hydraulics integrates the relevant physical, (bio)chemical and biological processes for the sediment-water exchange of substances. The aim of the diagenesis models is the prediction of both sediment quality and the return fluxes of substances such as nutrients and micropollutants to the overlying water. The resulting so-called DELWAQ-G model is a new, generic version of the water and sediment quality model of the DELFT3D framework. One set of generic water quality process formulations is used to calculate process rates in both water and sediment compartments. DELWAQ-G involves the explicit simulation of sediment layers in the water quality model with state-of-the-art process kinetics. The local conditions in a water layer or sediment layer such as the dissolved oxygen concentration determine if and how individual processes come to expression. New processes were added for sulphate, sulphide, methane and the distribution of the electron-acceptor demand over dissolved oxygen, nitrate, sulphate and carbon dioxide. DELWAQ-G also includes the dispersive and advective transport processes in the sediment and across the sediment-water interface. DELWAQ-G has been applied for the Wadden Sea. A very dynamic tidal and ecologically active estuary with a complex hydrodynamic behaviour located at the north of the Netherlands. The predicted profiles in the sediment reflect the typical interactions of diagenesis processes.

    The Wadden Sea bordering the Dutch, German and Danish coast, is traditionally a region with important functions for many fish species: as a nursery area for juveniles (marine juveniles), as a feeding area, as a transit to and from fresh water, and resident species complete their whole life cycle there. Because of indications that the importance of the Dutch Wadden Sea has changed drastically for many species during the past decades, we analysed and classified trends of 24 common fish species in the last 45 years, which were assigned to 5 different ecological guilds. Trends were examined for three Wadden Sea regions and compared to trends in the adjacent two North Sea coastal regions. For these analyses we made a combined use of two longterm time series: an annual beamtrawl survey, the Demeral Fish Survey (DFS) with a high spatial but poor seasonal resolution and a fyke series with a high seasonal but poor spatial resolution. We investigated for which species the DFS survey was appropriate for trend analysis, and we evaluated whether a change in timing may contribute to patterns in DFS time trends. Total fish biomass showed a similar pattern in all tidal basins with an increase from 1970 to 1980, a peak in the mid-1980s and a strong decline from 1980 to 2000, with a subsequent stable trend. The pattern in the coastal region deviated especially in the past 10 years, with a further decline along the Dutch Wadden coast and an increase along the mainland coast. Most dramatic declines throughout the Wadden Sea occurred in species belonging to the marine juvenile guild, notably plaice, sole and dab. A declining trend in marine juveniles is on-going in the western part, while it recently stabilised or even increased in the central and eastern part and in the coastal regions. Resident species showed more variable trends in the Wadden Sea with less pronounced directions: both increases and decreases occurred. In the coastal regions, several resident species have increased

  6. Population development and status of harbour seals (Phoca vitulina in the Wadden Sea

    Full Text Available An index for the condition of a population should include a measure of the recuperative power or resilience of the population in question. This measure needs to cover both the demographic and physiological condition of the population. Applied to the harbour seal population in the Wadden Sea we therefore address respectively the population development and distribution, and its health condition, and relate these to environmental conditions. The harbour seal population has been severely depleted by hunting in the first half of the 20th century. After hunting was stopped in the mid-1970s the population recovered gradually. This recovery was twice interrupted by Phocine Distemper Virus (PDV outbreaks in 1988 and 2002. These PDV-epizootics reduced the population by 57% and 50% respectively. They also lead to changes in age and sex structure of the population, which gradually returned to a stable age-structure. Despite the reduction in population size by respectively 57% and 50%, the population showed a strong recovery with a growth rate close to the considered maximum possible for this species. The observed changes in the distribution of the population over the 4 sub-regions indicate that distribution is not a static phenomenon. Long term field and pathological investigations point out that the general health status of the population has improved, particularly that of newborn seals (0-6months old. The increasing prevalence of parasites in lungs and intestine warrants continued monitoring of the health status of seals. This is especially relevant in view of the exponential increase of the population, which may finally approach the carrying capacity of the area. Concluding, we canstate that the condition of the population in terms of demographic and health parameters is satisfactory. The best guarantee for maintaining such a favourable conservation status is to abstain from human interferences (e.g. rescue, rehabilitation and release with natural

    Long-term eustatic sea-level variation has been recognized as a primary factor affecting the hydrological and geomorphic dynamics of salt marshes. However, recent studies suggest that wind waves influenced by atmospheric oscillations also may play an important role in many coastal areas. Although...... this notion has been conceptually introduced for the Wadden Sea, no modeling attempts have been made yet. As a proof of concept, this study developed a simulation model using the commercially available STELLAA (R) software, based on long-term data on water level and sedimentation collected at a back......-barrier marsh on the Skallingen peninsula in Denmark. In the model, the frequency (number year(-1)) of wind-driven extreme high water level (HWL) events (> 130 cm Danish Ordnance Zero) was simulated in terms of the North Atlantic Oscillation (NAO) index. Then, surface accretion (cm year(-1)) and submergence...

  9. Options for modulating intra-specific competition in colonial pinnipeds: the case of harbour seals (Phoca vitulina in the Wadden Sea

    Directory of Open Access Journals (Sweden)

    Rory P. Wilson

    2015-06-01

    Full Text Available Colonial pinnipeds may be subject to substantial consumptive competition because they are large, slow-moving central place foragers. We examined possible mechanisms for reducing this competition by examining the diving behaviour of harbour seals (Phoca vitulina after equipping 34 seals (11 females, 23 males foraging from three locations; Rømø, Denmark and Lorenzenplate and Helgoland, Germany, in the Wadden Sea area with time-depth recorders. Analysis of 319,021 dives revealed little between-colony variation but appreciable inter-sex differences, with males diving deeper than females, but for shorter periods. Males also had higher vertical descent rates. This result suggests that males may have higher overall swim speeds, which would increase higher oxygen consumption, and may explain the shorter dive durations compared to females. Intersex variation in swim speed alone is predicted to lead to fundamental differences in the time use of three-dimensional space, which may help reduce consumptive competition in harbour seals and other colonial pinnipeds.

    The digestive tracts of 90 oystercatchers (equal numbers of males and females and of juveniles, subadults and adults) wintering in the Dutch Wadden Sea were examined for helminth parasites. The nematodes Capillaria sp. (36.7%) and Streptocara crassicauda (7.8%) were found in the stomach. Unidentified cestodes (76.7%) and the trematodes Psilostomum brevicolle (42.2%), Notocotylus sp. (81.1%), and unidentified gymnophallids (100%) were found in the intestine and caeca. Two birds were infected with Gymnophallidae only, while all other birds contained additional helminth species. Compared with subadult and adult birds, the juveniles had significantly more infections with Capillaria sp. and cestodes. Moreover, the juveniles were infected with a greater variety of species. No further relation was found between the presence of helminths or worm numbers and age groups or sexes of birds.

  13. Tidal and seasonal variation in particulate and dissolved organic carbon in the western dutch Wadden Sea and Marsdiep tidal inlet

    Science.gov (United States)

    Cadée, G. C.

    Seasonal variation in POC and DOC was measured in the Marsdiep tidal inlet of the Wadden Sea from March 1978 to June 1981, and compared with tidal variation. A POC peak was coincident with the phytoplankton peak (except for 1981), whereas a DOC peak occurred about one month later indicating autolysis and degradation of phytoplankton rather than excretion as the main source of this DOC. DOC production calculated from the spring increase amounted to 4.2 mg C·1 -1 or about 40% of the annual phytoplankton primary production in the area. This means that a large part of the phytoplankton production is not used directly by primary consumers but is converted into DOC. Tidal variation in DOC was correlated with salinity, pointing to a fresh water source for the bulk of it. POC was correlated with suspended matter content and phaeopigment, and slightly less with chlorophyll. Compared with the seasonal variation, tidal variation in chlorophyll and temperature was relatively small, but large in POC, DOC, suspended matter and salinity. Although import of POC and export of DOC through the Marsdiep inlet is large on an annual base, the transport cannot be measured directly because of the variability and precision limits of the measurements and as differences in content between ebb and flood current are only 15 and 5% of the POC and DOC content, respectively.

    Growth studies based on population-based growth estimates are limited by the fact that they do not take into account differences in age/size structure within the population. To overcome these problems, otolith microstructure analysis is often used to estimate individual growth. Here, we analyse growth of 0-group plaice in the western Wadden Sea in two years: a year preceded by a mild winter (1995) and a year preceded by a severe winter (1996). Growth was analysed by combining information on individual growth based on otolith analysis with predictions of maximum growth (= under optimal food conditions) based on a Dynamic Energy Budget model. Otolith analysis revealed that settlement occurred earlier in 1995 than in 1996. In both years, one main cohort was found, followed by a group of late settlers. No differences in mean length-at-age were found between these groups. DEB modelling suggested that growth was not maximal during the whole growing season: realized growth (the fraction of maximum growth realized by 0-group plaice) declined in the summer, although this decline was relatively small. In addition, late settling individuals exhibited lower realized growth than individuals from the main cohort. This study confirms that growth conditions for 0-group plaice are not optimal and that a growth reduction occurs in summer, as suggested in previous studies.

    Full Text Available Lesser black-backed gulls Larus fuscus are considered to be mainly pelagic. We assessed the importance of different landscape elements (open sea, tidal flats and inland by comparing marine and terrestrial foraging behaviours in lesser black-backed gulls breeding along the coast of the southern North Sea. We attached GPS data loggers to eight incubating birds and collected information on diet and habitat use. The loggers recorded data for 10-19 days to allow flight-path reconstruction. Lesser black-backed gulls foraged in both offshore and inland areas, but rarely on tidal flats. Targets and directions were similar among all eight individuals. Foraging trips (n = 108 lasted 0.5-26.4 h (mean 8.7 h, and ranges varied from 3.0-79.9 km (mean 30.9 km. The total distance travelled per foraging trip ranged from 7.5-333.6 km (mean 97.9 km. Trips out to sea were significantly more variable in all parameters than inland trips. Presence in inland areas was closely associated with daylight, whereas trips to sea occurred at day and night, but mostly at night. The most common items in pellets were grass (48%, insects (38%, fish (28%, litter (26% and earthworms (20%. There was a significant relationship between the carbon and nitrogen isotope signals in blood and the proportional time each individual spent foraging at sea/land. On land, gulls preferentially foraged on bare ground, with significantly higher use of potato fields and significantly less use of grassland. The flight patterns of lesser black-backed gulls at sea overlapped with fishing-vessel distribution, including small beam trawlers fishing for shrimps in coastal waters close to the colony and large beam-trawlers fishing for flatfish at greater distances. Our data show that individuals made intensive use of the anthropogenic landscape and seascape, indicating that lesser black-backed gulls are not a predominantly marine species during the incubation period.

    The Wadden Sea is a large coastal transition area adjoining the southern North Sea uniting ecological key functions with an important role in coastal protection. The region is strictly protected by EU directives and national law and is a UNESCO World Heritage Site, requiring frequent quality assessments and regular monitoring. In 2014 an intertidal bedform area characterised by alternating crests and water-covered troughs on the tidal flats of the island of Norderney (German Wadden Sea sector) was chosen to test different remote sensing methods for habitat mapping: airborne lidar, satellite-based radar (TerraSAR-X) and electro-optical sensors (RapidEye). The results revealed that, although sensitive to different surface qualities, all sensors were able to image the bedforms. A digital terrain model generated from the lidar data shows crests and slopes of the bedforms with high geometric accuracy in the centimetre range, but high costs limit the operation area. TerraSAR-X data enabled identifying the positions of the bedforms reflecting the residual water in the troughs also with a high resolution of up to 1.1 m, but with larger footprints and much higher temporal availability. RapidEye data are sensitive to differences in sediment moisture employed to identify crest areas, slopes and troughs, with high spatial coverage but the lowest resolution (6.5 m). Monitoring concepts may differ in their remote sensing requirements regarding areal coverage, spatial and temporal resolution, sensitivity and geometric accuracy. Also financial budgets limit the selection of sensors. Thus, combining differing assets into an integrated concept of remote sensing contributes to solving these issues.

  5. Zoobenthic biomass limited by phytoplankton abundance: evidence from parallel changes in two long-term data series in the Wadden Sea

    2002-10-01

    We address the question of whether year-to-year variability in pelagic algal food supply can explain long-term variability in macrozoobenthic biomass in an estuarine area. Starting in the early 1970s, quantitative data were frequently collected in standardized ways in the western part of the Dutch Wadden Sea on (1) concentrations of phytoplankton species and chlorophyll (and rates of primary production) in the main tidal inlet (Marsdiep) and (2) numerical densities and biomass of macrozoobenthic animals (and growth rates in a few species) in a nearby extensive tidal-flat area (Balgzand). In both data series, the most distinctive feature was a sudden change that took place around 1980, viz. a rather sudden and persisting doubling of concentrations of chlorophyll and algal cells and of primary production rates, as well as of numerical densities and biomass of zoobenthos. From these parallel changes we hypothesise that algal food largely determines the abundance of zoobenthos in the Wadden Sea. The following observations substantiate this hypothesis: (1) the significant correlation between annual mean values of chlorophyll concentration and overall mean numerical density and biomass of zoobenthos (as estimated after an appropriate time lag), (2) the observed limitation of zoobenthic biomass doubling (after the doubling of food supply) to areas with already high biomass values (where food demand was high and food could therefore be in short supply), (3) the limitation of a strong response to changes in food supply to functional groups that are directly dependent on algal food, i.e. suspension and deposit feeders, as opposed to carnivores, (4) the significant correlation between annual growth rates in Macoma balthica and food supply in the growing season, particularly in areas close to the tidal inlet where food concentrations were monitored. Some other factors were identified that could decisively influence zoobenthic abundance locally and/or temporarily. Harsh

    2016-07-01

    Marine environmental conditions are naturally changing throughout the year, affecting life cycles of hosts as well as parasites. In particular, water temperature is positively correlated with the development of many parasites and pathogenic bacteria, increasing the risk of infection and diseases during summer. Interannual temperature fluctuations are likely to alter host-parasite interactions, which may result in profound impacts on sensitive ecosystems. In this context we investigated the parasite and bacterial Vibrionaceae communities of four common small fish species (three-spined stickleback Gasterosteus aculeatus, Atlantic herring Clupea harengus, European sprat Sprattus sprattus and lesser sand eel Ammodytes tobianus) in the Northern Wadden Sea over a period of two years. Overall, we found significantly increased relative diversities of infectious species at higher temperature differentials. On the taxon-specific level some macroparasite species (trematodes, nematodes) showed a shift in infection peaks that followed the water temperatures of preceding months, whereas other parasite groups showed no effects of temperature differentials on infection parameters. Our results show that even subtle changes in seasonal temperatures may shift and modify the phenology of parasites as well as opportunistic pathogens that can have far reaching consequences for sensitive ecosystems.

  8. On the dynamics of compound bedforms in high-energy tidal channels: field observations in the German Bight and the Danish Wadden Sea

    2010-05-01

    Tidal inlets are a common feature along much of the world's coastlines. They interrupt the alongshore continuity of shoreline processes, and by being exposed to both wave and current forcing, tidal inlets belong to the morphologically most dynamic and complex coastal systems on Earth. The tidal channels in these inlets are characterized by high flow velocities and, accordingly, the channel beds are typically sandy and covered with bedforms. The bedform fields in nature are often complex systems with larger primary-bedforms superimposed by smaller secondary-bedforms (cf. Bartholdy et al., 2002). There is a considerable amount of detailed field investigations on the dynamics of primary-bedforms at various temporal scales, ranging from short- to long-term tide-related cycles to flood hydrographs to seasonality. However, Julien et al. (2002) stated that a composite analysis of primary- and secondary-bedforms is recommended for future studies on resistance to flow. Such knowledge on the behaviour of compound bedforms is still deficient. In this study, we combine the findings on the dynamics of primary- and secondary-bedform height from detailed field investigations carried out in two high-energy tidal channels during 2007 and 2008: the Knudedyb tidal inlet channel in the Danish Wadden Sea and the Innenjade tidal channel in the Jade Bay, German Bight (both survey areas being ebb-dominated). We provide process-based explanations of the bedform behaviour and present a conceptual model of compound bedform dynamics. The conducted field investigations comprised repetitive, simultaneous measurements of high-resolution swath bathymetry (using a multibeam echosounder system) and flow velocity (using an acoustic Doppler current profiler) in combination with detailed spatial mapping of bed material characteristics (from grab sampling of bed material). For an objective and discrete analysis of primary- and secondary-bedforms a modified version of the bedform tracking tool

    Depositional processes in intertidal areas are determined both by changes in sea-level and sediment supply. It is known on a millennial timescale that sedimentation normally keeps pace with sea-level rise in a subsiding tidal basin. However, little is known about whether the sedimentation can kee...

    Flow networks of nine sub-systems consisting of 59 components each of the Sylt-Rømø Bight, German Wadden Sea, were constructed depicting the standing stocks and flows of material and energy within and between the sub-systems. Carbon, nitrogen and phosphorous were used as currencies for each sub-system, thus resulting in 27 network models, which were analyzed by ecological network analytical protocols. Results show substantial variability in the dynamics of these elements within and between the nine sub-systems, which differ in habitat structure, species diversity and in the standing stocks of their constituent living and non-living components. The relationship between the biodiversity and selected information indices and ratios, derived from ecological network analysis, of individual sub-systems is variable and differ substantially between them. Ecosystem properties such as the structure and magnitude of the recycling of these elements, number of cycles, and total sub-system activity were calculated and discussed, highlighting the differences between and complexity of the flow of C, N and P in a coastal marine ecosystem. The average number of cycles increase from 179 for C, to 16,923 and 20,580 for N and P respectively, while the average amount of recycled material, as measured by the Finn Cycling Index (FCI), increase from 17% for C, to 52% for P and to 61% for N. The number of cycles and the FCI vary considerably between the sub-systems for the different elements. The largest number of cycles of all three elements was observed in the muddy sand flat sub-system, but the highest FCIs were computed for both C (32%) and N (85%) in the Arenicola Flats, and in sparse Zostera noltii sea grass beds for P (67%). Indices reflecting on the growth, organization and resilience of the sub-systems also showed considerable variability between and within the inter-tidal ecosystems in the Bight. Indices such as, for example, the relative ascendency ratios increase on average

    A 40-y series of consistently collected samples (15 fixed sampling sites, constant sampled area of 15 × 0.95 m2, annual sampling only in late-winter/early-spring seasons, and consistent sieving and sorting procedures; restriction to 50 easily recognizable species) of macrozoobenthos on Balgzand, a tidal flat area in the westernmost part of the Wadden Sea (The Netherlands), revealed significantly increasing trends of species richness. Total numbers of species annually encountered increased from ~28 to ~38. Mean species density (number of species found per sampling site) increased from ~13 to ~18 per 0.95 m2. During the 40 years of the 1970-2009 period of observation, 4 exotic species invaded the area: (in order of first appearance) Ensis directus, Marenzelleria viridis, Crassostrea gigas, and Hemigrapsus takanoi. Another 5 species recently moved to Balgzand from nearby (subtidal) locations. Together, these 9 new species on the tidal flats explained by far most of the increase in total species numbers, but accounted for only one-third of the observed increase in species density (as a consequence of the restricted distribution of most of them). Species density increased particularly by a substantial number of species that showed increasing trends in the numbers of tidal flat sites they occupied. Most of these wider-spreading species were found to suffer from cold winters. During the 40-y period of observation, winter temperatures rose by about 2°C and cold winters became less frequent. The mean number of cold-sensitive species found per site significantly increased by almost 2 per 0.95 m2. Among the other species (not sensitive to low winter temperatures), 6 showed a rising and 2 a declining trend in number of occupied sites, resulting in a net long-term increase in species density amounting to another gain of 1.6 per 0.95 m2. Half of the 50 studied species did not show such long-term trend, nor were invaders. Thus, each of 3 groups (local or alien invaders

    Parasites were collected from 107 harbour seals ( Phoca vitulina) found on the coasts of Schleswig-Holstein, Germany, between 1997 and 2000. The prevalence of the parasites and their associated pathology were investigated. Eight species of parasites, primarily nematodes, were identified from the examined organs: two anisakid nematodes ( Pseudoterranova decipiens (sensu lato) , Contracaecum osculatum (sensu lato)) from the stomach, Otostrongylus circumlitus (Crenosomatidae) and Parafilaroides gymnurus (Filaroididae) from the respiratory tract, one filarioid nematode ( Acanthocheilonema spirocauda) from the heart, two acanthocephalans, Corynosoma strumosum and C. semerme (Polymorphidae), from the intestine and an ectoparasite, Echinophthirius horridus (Anoplura, Insecta). Lungworm infection was the most prominent parasitological finding and secondary bacterial bronchopneumonia the most pathogenic lesion correlated with the parasites. Heavy nematode burdens in the respiratory tract were highly age-related and more frequent in young seals. A positive correlation was observed between high levels of pulmonary infection and severity of bronchopneumonia. The prevalence of lungworms in this study was higher than in seals that died during the 1988/1989 Phocine Distemper Virus epidemic, and the prevalence of acanthocephalans and heartworms had decreased compared to findings from the first die-off.

    Hidden for the untrained eye through a thin layer of sand, laminated microbial sediments occur in supratidal beaches along the North Sea coast. The inhabiting microbial communities organize themselves in response to vertical gradients of light, oxygen or sulfur compounds. We performed a fine-scale investigation on the vertical zonation of the microbial communities using a lipid biomarker approach, and assessed the biogeochemical processes using a combination of microsensor measurements and a 13C-labeling experiment. Lipid biomarker fingerprinting showed the overarching importance of cyanobacteria and diatoms in these systems, and heterocyst glycolipids revealed the presence of diazotrophic cyanobacteria even in 9 to 20 mm depth. High abundance of ornithine lipids (OL) throughout the system may derive from sulfate reducing bacteria, while a characteristic OL profile between 5 and 8 mm may indicate presence of purple non-sulfur bacteria. The fate of 13C-labeled bicarbonate was followed by experimentally investigating the uptake into microbial lipids, revealing an overarching importance of cyanobacteria for carbon fixation. However, in deeper layers, uptake into purple sulfur bacteria was evident, and a close microbial coupling could be shown by uptake of label into lipids of sulfate reducing bacteria in the deepest layer. Microsensor measurements in sediment cores collected at a later time point revealed the same general pattern as the biomarker analysis and the labeling experiments. Oxygen and pH-microsensor profiles showed active photosynthesis in the top layer. The sulfide that diffuses from deeper down and decreases just below the layer of active oxygenic photosynthesis indicates the presence of sulfur bacteria, like anoxygenic phototrophs that use sulfide instead of water for photosynthesis.

  1. How the food supply harvestable by waders in the Wadden Sea depends on the variation in energy density, body weight, biomass, burying depth and behaviour of tidal-flat invertebrates

    Science.gov (United States)

    Zwarts, Leo; Wanink, Jan H.

    For several reasons, waders in the Wadden Sea face a large seasonal and annual variation in their food supply. Observations on a tidal flat in the Dutch Wadden Sea have shown that: - (1) The average energy density of ten invertebrate prey species varies between 21 and 23 kJ·g -1 AFDW. In Scrobicularia plana and Mya arenaria, but not in Macoma balthica, the energy density is 10% lower in winter than in summer. - (2) Depending on the species, body weights of prey of similar size are 30 to 60% lower in winter than in summer. - (3) The year-to-year fluctuation in standing-crop biomass is larger in some species than in others, the difference depending mainly on the frequency of successful recruitment. The overall biomass of the macrobenthos in winter is half of that in summer, but the timing of the peak biomass differs per species. - (4) The burying depth varies per species: Cerastoderma edule live just beneath the surface, while M. balthica, S. plana, M. arenaria, Arenicola marina and Nereis diversicolor bury more deeply and the majority of these prey live out of reach of the bird's bill. In all six species, burying depth increases with size. There is no seasonal variation in depth of C. edule and M. arenaria, but the four other species live at most shallow depth in early summer and most deeply in midwinter. Burying depths in winter vary from year to year, but are unrelated to temperature. Neither has temperature any effect on depth within months. For knot Calidris canutus feeding on M. balthica, the fluctuation in the accessible fraction was the main source of variation in the biomass of prey that is actually harvestable, i.e. the biomass of prey of suitable size that is accessible. Accordingly, the paper reviews the available data on the temporal variations in accessibility, detectability, ingestibility, digestibility and profitability of prey for waders. Only a small part of the prey is harvestable since many accessible prey are ignored because of their low

    This paper reports on SEA applied in the wind energy sector in the UK and Germany. Based on a review of 18 SEAs, it is found that the quality of SEA documentation is variable, with over a third of them being deemed unsatisfactory. Furthermore, SEA processes are conducted to varying degrees of effectiveness, with scoping a strength but impact prediction and mitigation weaknesses. Generally speaking, the influence of SEA on German wind energy plan making was found to be low and the influence of SEA on UK plans deemed to be moderate. The German plans had a low influence mainly because of a perceived high environmental performance of the underlying plans in the first instance. Substantive outcomes of SEA are not always clear and the influence of SEA on decision making is said to be limited in many cases. Finally, a lack of effective tiering between SEA and project level EIA is also observed. In addition, our findings echo some of the weaknesses of SEA practice found in previous studies of SEA effectiveness, including poor impact prediction and significance sections and a lack of detailed monitoring programmes for post plan implementation.

    This paper presents results of an international comparative research project, funded by the UK Economic and Social Research Council (ESRC) and the Academy for Sustainable Communities (ASC) on the 'learning potential of appraisal (strategic environmental assessment - SEA) in spatial planning'. In this context, aspects of 'single-loop' and 'double-loop' learning, as well as of individual, organisational and social learning are discussed for emerging post-EC Directive German practice in the planning region (Zweckverband) of Brunswick (Braunschweig), focusing on four spatial plan SEAs from various administrative levels in the region. It is found that whilst SEA is able to lead to plan SEA specific knowledge acquisition, comprehension, application and analysis ('single-loop learning'), it is currently resulting only occasionally in wider synthesis and evaluation ('double-loop learning'). Furthermore, whilst there is evidence that individual and occasionally organisational learning may be enhanced through SEA, most notably in small municipalities, social learning appears to be happening only sporadically.

    This report is an analysis of the planned gas pipeline from Russia to Germany through the Baltic Sea known as Nord Stream. Although not yet realised, the project has, since its birth, been the subject of harsh criticism and opposition by a significant number of states that consider themselves affected by the pipeline. Whereas the Baltic States and Poland have interpreted the pipeline as a politically motivated strategy that will increase Russia's leverage on them and threaten their energy security, the debate in Sweden was at first mostly concerned with the prospect of increased Russian military presence in the Swedish Exclusive Economic Zone. The potential environmental impact of the pipeline has been, and continues to be, an overarching concern shared by all the littoral states of the Baltic Sea. Proponents of Nord Stream, most notably Germany, Russia and the Nord Stream consortium, have largely dismissed the concerns as unwarranted and argue that the pipeline is a common European project that all EU-members should embrace, as it will provide much-needed gas to an increasingly energy-thirsty union. This report is an extensive study of the divergent attitudes and debates that have surged in the region regarding Nord Stream, and the aim is to provide plausible explanations as to why the interpretations of the project have been so different in the various states. The report is based on a variety of sources, including several first-hand interviews with researchers and government officials in the Baltic Sea region. (author). refs.,fig.,tabs

  9. The significance of radionuclides and trace elements in a back barrier tidal area: Results from the German Wadden

    Coastal areas like the German Wadden Sea are characterised by processes occurring on short (tides) seasonal (winter/summer), and long (sea level rise) timescales. This causes fluctuations in biological, chemical and physical parameters. In the geological past these parameters were driven by natural mechanisms whereas in the last centuries anthropogenic influences (coastal protection, agriculture) became important. It is more or less unknown how the different processes forming the German Wadden Sea interact together. We investigated the dissolved and particulate phase of the waters of the a back barrier tidal area of the East Frisian Islands. Intertidal and seasonal variations in radionuclides, alkalinity and redox-sensitive trace metals give us evidence to several important sources and processes going on in this area. In summer, spring and autumn, alkalinity as well as Mn concentrations in the dissolved phase are high during low tide and low during high tide. In winter, alkalinity and Mn concentration in the dissolved phase is lower. In the suspended particulate material a high and variable Mn/Al ratio during tidal cycles was found in summer and autumn. A low ratio close to average shale with minor variations during low and high tide was found in winter and spring. Stable sulphur isotopes measured in porewater draining the tidal flats during low tide indicate intense diagenesis by sulphate reducing bacteria. These observations point to a seasonal, microbially driven release of dissolved Mn and carbon species from the subsurface anoxic Wadden Sea sediments. Another source, adding dissolved components to the water of the back-barrier area, can be identified by short lived radium isotopes. 223 Ra and 224 Ra were found to vary by a factor of two during tidal cycles. Most possibly, the source for Ra are the subterranean sands, which are drained during low tide and replenished during high tide.

Although not yet realised, the project has, since its birth, been the subject of harsh criticism and opposition by a significant number of states that consider themselves affected by the pipeline. Whereas the Baltic States and Poland have interpreted the pipeline as a politically motivated strategy that will increase Russia's leverage on them and threaten their energy security, the debate in Sweden was at first mostly concerned with the prospect of increased Russian military presence in the Swedish Exclusive Economic Zone. The potential environmental impact of the pipeline has been, and continues to be, an overarching concern shared by all the littoral states of the Baltic Sea. Proponents of Nord Stream, most notably Germany, Russia and the Nord Stream consortium, have largely dismissed the concerns as unwarranted and argue that the pipeline is a common European project that all EU-members should embrace, as it will provide much-needed gas to an increasingly energy-thirsty union. This report is an extensive study of the divergent attitudes and debates that have surged in the region regarding Nord Stream, and the aim is to provide plausible explanations as to why the interpretations of the project have been so different in the various states. The report is based on a variety of sources, including several first-hand interviews with researchers and government officials in the Baltic Sea region. (author). refs.,fig.,tabs

    Dumped ammunition in the sea is a matter of great concern in terms of safe navigation and environmental threads. Because corrosion of the dumped ammunition's hull is ongoing, future contamination of the ambient water by their toxic interior is likely to occur. The location of such dump sites is approximately known from historical research and ship log book analyses. Subsequent remote sensing of ammunition dumping sites (e.g. mines) on the seafloor is preferentially performed with hydro-acoustic methods such as high resolution towed side scan or by the sophisticated synthetic aperture sonar approach with autonomous underwater vehicles. However, these are time consuming and expensive procedures, while determining the precise position of individual mines remains a challenging task. To mitigate these shortcomings we suggest using ship-born high-frequency multibeam sonar in shallow water to address the task of mine detection and precise localization on the seabed. Multibeam sonar systems have improved their potential in regard to backscatter analyses significantly over the past years and nowadays present fast and accurate tools for shallow water surveying to (1) detect mines in multibeam snippet backscatter data (2) determine their precise location with high accuracy intertial navigation systems. A case study was performed at the prominent ammunition dumping site 'Kolberger Heide' (Baltic Sea, Germany) in the year 2014 using a modern hydro-acoustic multibeam echosounder system with 200-400 kHz (KONGSBERG EM2040c). With an average water depth of not even 20 m and the proximity to the shore line and dense waterways, this investigated area requires permanent navigational care. Previously, the study area was surveyed by the Navy with the very sophisticated HUGIN AUV equipped with a synthetic aperture sonar with best resolution by current technology. Following an evaluation of the collected data, various ammunition bodies on the sea floor could be clearly detected. Analyses

  14. Interplay of salt dynamics, sea-level change and climate on the depositional evolution of a Paleogene economic coal bearing salt rim syncline, Schoeningen, Germany

    The Paleogene basin fill (maximum 300 m thick) of the Schoeningen rim syncline in northern Germany is well known for its economic lignitic coal deposits. The fill provides an example of the interaction of basin subsidence, sea-level, and climate changes on depositional environment and gives insight into the development of the coal seams within a sequence stratigraphic context. The rim syncline records thirteen Lower to Middle Eocene coal seams with intervening clastic layers that were deposited during a long-lived transgression of the Central German Estuary, which lasted until the Late Oligocene (Standke, 2008). The previous analysis of the rim syncline fill has primarily focused on coal deposits, their lateral extent and paleo-botanical habitat. In this work, 357 lithologic logs were calibrated to outcrop profiles and integrated with previous studies to provide a facies analysis and sequence stratigraphy interpretation of the syncline fill. This improves understanding of the depositional environments of the lesser-studied clastics that intervene the coals (Osman et al., in review). Four 3{sup rd} order sequences are recorded in the Lower to Middle Eocene basin fill. Sequences 1 and 2 document the interplay of sands and coals within a transgressive estuarine phase. The sands show a regime change from tide- to more wave-dominated estuarine conditions before a turnaround to a regressive deltaic phase. This succession typifies an incised valley fill. However, the accommodation space generated for the initial estuary development is thought to have originated via continual salt withdrawal (Brandes et al. 2012) instead of by incision during relative sea-level fall. The observed tide to wave estuary regime change is linked to increased subsidence rates at 57 Ma that generated a higher tidal prism. As the subsidence rates slowed and the syncline broadened, the tidal prism decreased, leading to the development of more wave-dominated facies. The intervening coal seams

    Once an abundant fish species in the rivers of the Wadden Sea in northwest Europe, the North Sea houting Coregonus oxyrinchus (NSH) was at the brink of extinction 25 yr ago. The very last stronghold for this species was in the small Danish River Vidaa. In an attempt to preserve this anadromous...... whitefish species, juveniles were hatchery-reared and stocked in 6 Danish rivers flowing into the Wadden Sea. These stocking efforts were fairly successful, and the houting established populations in at least 2 of the rivers, but the underlying problem of habitat degradation and migration obstacles...... they reach sexual maturity, NSH grow relatively slowly (mean: 2.55 cm yr−1, ranging from 0 to 13.8 cm yr−1) and can reach an age of 10 to 12 yr.

    Within the framework of the title drilling activities the NAM carries out a MER. Several research institutes were asked to contribute to the MER. The authors' institute was asked to describe the ecology of the exploration areas in the Wadden Sea, as well as the possible effects of the exploration drilling on the ecology. In this report only the impact for the Wadden Sea is dealt with. In chapter 1 the ecology of the Wadden Sea is discussed in detail for the subjects primary production (photosynthesis), secondary production (consumption of vegetable organic materials), birds, seals, and societal functions. In chapter 2 specific aspects of specific sites are outlined. In chapter 3 an overview (the so-called factor train) is given of the activities around the exploration drilling of the NAM in the Wadden Sea and the disturbances that can be the result of those activities. In chapter 4 the possible effects of exploration drilling on birds and seals are discussed for each drilling site

    Cegelec is a group of companies acting internationally and one of Europe's biggest plant engineering firms in the fields of power generation and distribution with the focus on engineering and technical services. Cegelec's competences in Germany are mainly in planning, installation and maintenance of plants and facilities in all key industries and for public clients. The main areas of activity are industry, infrastructure and power, for which Cegelec offers comprehensive project and service work. While the Industry business area covers chemistry, steel, paper, automotive, re-engineering, and mining industries, Cegelec's Infrastructure unit performs services to airports, in tunnel construction, for railways and waterways. The Power market segment comprises gas, refuse incineration, power supply, sugar, power plants, and nuclear final storage. Cegelec is represented in Germany on roughly 30 locations with a staff of 1,700. The origins of Cegelec are in Germany, i.e. in AEG founded 1896. The Plant and Automation Technology sector was divested in 1996 and moved to Alstom where, in 2001, a management buyout led to the independent Cegelec group of companies. When the strategic partnership between Qatari Diar and Vinci took shape, Cegelec became a subsidiary of the Vinci group in April 2010. (orig.)

  7. Barrier response to Holocene sea-level rise

    Pejrup, Morten; Andersen, Thorbjørn Joest; Johannessen, Peter N

    Normally it is believed that sea-level rise causes coastal barrier retreat. However, sea-level is only one of the parameters determining the long term coastal development of barrier coasts. Sediment supply is an equally important determinant and may overshadow the effects of sea-level rise....... Conceptually this has been known for a long time but for the first time we can show the relative effect of these two parameters. We have studied three neighboring barrier islands in the Wadden Sea, and described their 3D morphological evolution during the last 8000 years. It appears that the barrier islands...... a much stronger component of sea-level control. The distance between the islands is only 50 km, and therefore our study shows that prediction of barrier development during a period of rising sea level may be more complicated than formerly believed....

  8. Sandstone compaction under actively controlled uniaxial strain conditions - an experimental study on the causes of subsidence in the Dutch Wadden Area

    In the Wadden Sea, a tidal-flat area located between the North Sea and the Dutch mainland shore, and UNESCO World Heritage site, subsidence could potentially impact the ecological system. To guide the licensing process governing gas extraction for the area by a solid understanding of the system's response to production, Nederlandse Aardolie Maatschappij (NAM) has carried out a study on the magnitudes, timing, and mechanisms of subsidence related to gas production. As part of this study program, we address the effect of production-induced reservoir compaction, using core samples from the Moddergat field located at the Wadden Sea coastline, from a depth of ~3800 m TVDSS, to assess the nature of the compaction mechanisms that operate. In this contribution, we focus on the uniaxial strain response of Permian, Aeolian sandstone to pore pressure depletion. As the majority of experiments reported in the literature are conducted under triaxial stress conditions, this data set is somewhat unique, and can help confirm the validity of micromechanical processes found for triaxial stress conditions. We report over 30 data sets of experiments carried out using 1.0 and 1.5 inch diameter plugs, sub-sampled from the extracted sandstone core material. The experiments start at in-situ conditions of pore pressure (Pf=~57 MPa), stress (Sv=~80 MPa, Sh=~67 MPa) and temperature (T up to 100 °C), and deplete to a pore pressure of 3 MPa, under actively controlled lateral constraint boundary conditions (i.e. uniaxial strain). Care was taken to systematically vary porosity and sample morphology to ensure representation of the intra-reservoir variability. Our laboratory data show that pressure-depletion results in a strain in the range of 5·10-3-1·10-2 over the total duration of the experiments of 5-12 weeks, with approximately 80% of the total strain response being close to instantaneous, and 20% developing over time. The total strain response develops during depletion as a result of

    2017-04-01

    Both the temporal and spatial variability of storm surge water level (WL) curves are usually not taken into account in flood risk assessments as observational data are often scarce. In addition, sea-level rise (SLR) can further affect the variability of WLs. We analyze the temporal and spatial variability of the WL curve of 75 historical storm surge events that have been numerically simulated for St. Peter-Ording at the German North Sea coast, considering the effects induced by three SLR scenarios (RCP 4.5, RCP 8.5, and a RCP 8.5 high end scenario). We assess potential impacts of these scenarios on two parameters related to flooding: overflow volumes and fullness. Our results indicate that due to both the temporal and spatial variability of those events the resulting overflow volume can be two or even three times greater. We observe a steepening of the WL curve with an increase of the tidal range under the three SLR scenarios, although SLR induced effects are relatively higher for the RCP 4.5. The steepening of the WL curve with SLR produces a reduction of the fullness, but the changes in overflow volumes also depend on the magnitude of the storm surge event.

    The exploration of the arctic seas require an integrated approach applying different infrastructures. In Fall 2009 German and Russian scientists performed a geo marine cruise off Kamchatka and in the western Bering Sea within the frame of the KALMAR-Project. Two main research subjects formed the scientific backbone of the cruise: The first objective focuses on the geodynamic and volcanological-magmatic development of the Kuril-Kamchatka island arc system and the Kamchatka Aleutean Islands Triple-Junction. Very little is known about the composition of the mantle and the oceanic crust as well as of the seamounts including their ages. The best studied site is the Volcanologist's Massif located between the Bering- and the Alpha Fracture Zone (Tsvetkov 1990, Volynets et al. 1992, Yogodzinsky et al. 1994), which structurally belongs to the Komandorsky Basin. The oldest rocks of the Volcanologist's Massif show very similar trace element and isotope signatures like those rocks cropping out in the volcanoes on Kamchatka in the prolongation of the Alpha Fracture Zone (Portnyagin et al. 2005a), indicating similar conditions of magma formation. The top of the Volcanologist's Massif is characterized by the young (Emperor-Seamount chain, having an age of probably > 85 Ma. The only existing basement rocks from this seamount were gained during DSDP Leg 19. These are basalts with MORB like trace element and isotope signatures (Keller et al. 2000, Regelous et al. 2003). These data indicate that the Hawaii-Hotspot was at a MOR in Cretaceous time and that large volumes of depleted mantle material played a role during the magma formation. The second objective focuses on paleo-oceanographic investigations concentrating on the sediments along the eastern continental slope of Kamchatka, in the Komandorsky Basin, and on the Shirshov Ridge in order to explore paleoclimate archives to better understand the subpolar water mass transfer and the oceanographic and climatic development in the

    Full Text Available An accurate estimation of the chlorophyll-a (Chla concentration is crucial for water quality monitoring and is highly desired by various government agencies and environmental groups. However, using satellite observations for Chla estimation remains problematic over coastal waters due to their optical complexity and the critical atmospheric correction. In this study, we coupled an atmospheric and a water optical model for the simultaneous atmospheric correction and retrieval of Chla in the complex waters of the Wadden Sea. This coupled model called MOD2SEA combines simulations from the MODerate resolution atmospheric TRANsmission model (MODTRAN and the two-stream radiative transfer hydro-optical model 2SeaColor. The accuracy of the coupled MOD2SEA model was validated using a matchup data set of MERIS (MEdium Resolution Imaging SpectRometer observations and four years of concurrent ground truth measurements (2007–2010 at the NIOZ jetty location in the Dutch part of the Wadden Sea. The results showed that MERIS-derived Chla from MOD2SEA explained the variations of measured Chla with a determination coefficient of R2 = 0.88 and a RMSE of 3.32 mg·m−3, which means a significant improvement in comparison with the standard MERIS Case 2 regional (C2R processor. The proposed coupled model might be used to generate a time series of reliable Chla maps, which is of profound importance for the assessment of causes and consequences of long-term phenological changes of Chla in the turbid Wadden Sea area.

    The Wadden Sea is an area of tidal flats and salt marshes extending between the North Sea coasts of Denmark, Germany and the Netherlands. It has enormous value as a cleansing site for North Sea water, as a nursery for young fish and as a feeding ground for many bird species. Due to the proximity of important shipping routes and harbours, this region is especially threatened by oil spills. Thus, for oil spill response and precaution measures, a sensitivity study of the entire intertidal area was badly needed in order to assess and minimize the potential ecological and economical damage. Based on comprehensive field surveys and in close cooperation with the Central Command for Maritime Emergencies, an automated expert-model for the german part of Wadden Sea areas was developed at the Institute for Coastal Research (GKSS-Research Centre). As an operational model it will serve as important instrument for decision making processes, precautionary measures and the further design of oil spill response strategies. Since it is not possible to protect the entire German North Sea coast equally at all levels, oil spill contingency planning requires a more detailed classification. For this reason, individual soft bottom habitats, communities and stocks of saltmarshes, macrofauna, waterfowl and estuarine biotop types were evaluated and classified according to their vulnerability to oil pollution. Hence, the fieldwork for habitat mapping during 2003-2006 was a central part of the study. For this part, the experiences and results obtained from the previous GKSS-project ''Thematic mapping and sensitivity study of Intertidal flats'' during the years 1987-1992 served as an valuable basis. For example, the documentation of changes during these periods of observation provides information on stability features of the ecosystems. During the first project nearly 5000 locations were processed and characterised using about 70 parameters for each site. The in-situ mapping

    Record year 2014. In Germany, the expansion figures attained were so high on land and at sea that the overall new installation figure of 5,188 MW surpassed the previous maximum (from 2002) by more than 60%. With an overall capacity of 39,259 MW, for the first time, wind energy in Germany covers 9.7% of gross power consumption. On the global scale a capacity of more than 51,000 MW has been added - another record high for wind energy installations. Power mix. At 161 TWh, renewable energies in Germany covered 27.8% of gross power consumption and provided for the first time more energy than any other energy source. Coming into force of the new REA in August 2014, modified support schemes caused the expansion of biogas plants and large-scale PV installations to falter. The record expansion seen for wind energy can be interpreted as a pull-forward effect due to the tender procedures coming into force in 2017. Grid integration. Loss of production caused by feed-in management measures rose by 44% to 555 GWh as compared to 2012. Wind turbines were affected in 87% of cases but the impact on PV installations is increasing. Power generation must be more flexible and grids expanded to limit loss of production. Of the 23 expansion projects (1,887 km) in the Electricity Grid Expansion Act, just a quarter of them had been realized by the end of 2014 (463 km). In the preliminary analysis results for the 2014 grid development plan, the extent of grid upgrading and conversion was 3050 km. Offshore, the HelWin 1 grid link with a capacity of 580 MW went online. SylWin 1 and BorWin 2, with a total capacity of 1660 MW, are currently being tested in a trial. In the preliminary analysis results for the 2014 offshore grid development plan, grid connections having an overall capacity of 10.3 GW are planned.

    Germany was divided into two parts after World War II. The closed border and a nonconvertible currency in the Eastern part were the factors that did not allow a drug market to develop. Alcohol and medicaments were used as substitute drugs. Since Germany was reunified 5 years ago, there are now the same conditions prevailing for the procurement and sale of drugs in East Germany as there are in the Western German states. This report describes the current state of drug traffic, especially in Saxony, under the new social conditions.

    This article first recalls and comments the objectives defined in March 2007 by the European Council in terms of energy to struggle against climate change. These objectives relate to the reduction of greenhouse gas emissions, to renewable energies, to energy saving, and to the share of biofuels. It outlines that Germany worries about the political situation in Russia and the capacities of this country to supply Europe with hydrocarbons. Figures related to consumption of primary energy and to sources of production of electricity in Germany show that Germany is facing an increased energy dependency. The issues related to the relationship between the EU and Russia in the field of energy are further discussed, notably from the German point of view, but also from a European point of view as the EU expects a stronger reaction of Germany in front of the Russian situation

    Germany has about the same proportion of foreigners in its population as the United States, it is an immigration country. In a way, Germany has let immigration happen, but it did not really have an explicit immigration policy in the past. Now it has to make up its mind on its immigration policy in the future. The paper looks at the experience with immigration in the past, at the integration of foreigners and at the issues of immigration policy.

  14. Multiculturalism in Germany

    Milan Mesić

    2010-12-01

    Full Text Available The paper starts out from the recent statement by the German Chancellor Angela Merkel that multiculturalism in Germany is dead. The author draws attention to the unfavourable conditions for the development of multiculturalism in Germany. The reasons are historical, especially the experience of Nazism as well as the German social state. Namely, foreign workers in Germany, although without political rights and socially non-integrated, enjoyed a high degree of working and social rights, including high employment security. In this respect their position significantly differed from that of American workers (immigrants, which is why the struggle for civil rights was not in the foreground for German immigrants. Therefore, “the crisis of multiculturalism” appeared with the immigrants’ “second generation” (children, who have been first hit in the current times of crisis and the increasing deregulation of the labour market. They have remained socially non-integrated and without civil and political rights. It is interesting that the churches, particularly the Protestant one, lead in Germany in the efforts to begin to look at immigrants in a cultural (human sense as well, and have thus been the first to acknowledge that Germany has become a multicultural society. But this term and concept in Germany have remained sketchy, both in the theoretical and political sense. However, they have gained certain sympathy, mainly in parts of liberal-democratic circles – the Green Party leading the way – but more in a symbolic sense in countering xenophobia and cultural exclusion in German society. When multiculturalism was accused of developing “parallel society”, both the right and the left renounced it in favour of the (seemingly neutral concept of integration. The author proves that Germany has become and has remained multicultural, although not a multiculturalist country.

    Over the past two decades, Germany has gained a substantial amount of experience in the decommissioning of nuclear facilities of different types and sizes. Many research reactors and all prototype nuclear power plants, as well as a few larger nuclear power plants and fuel cycle facilities, are currently at varying stages of decommissioning. Several facilities have been fully dismantled and the sites have been cleared for reuse. The decommissioning projects comprise 18 power and prototype reactors, 33 research reactors and 11 fuel cycle facilities which are being or have been decommissioned. In the future, further nuclear power plants will be shut down and decommissioned in accordance with Germany?s energy policy to phase out the use of nuclear power for commercial electricity generation as given in the April 2002 amendment of the Atomic Energy Act. Radioactive waste, from operations as well as from decommissioning activities, is to be conditioned in such a way as to comply with the waste acceptance requirements of a repository. In Germany, all types of radioactive waste (i.e., short-lived and long-lived) are to be disposed of in deep geological formations. A distinction is being made for heat generating waste (i.e., high level waste) and waste with negligible heat generation (i.e., low level and intermediate level waste). Radioactive decommissioning waste is waste with negligible heat generation. Waste acceptance requirements of a repository are of particular importance for the conditioning of radioactive waste, including decommissioning waste. The waste acceptance requirements, as they resulted from the Konrad licensing procedure, are being applied by the waste generators for the conditioning of decommissioning waste. Compliance with these requirements must be demonstrated through the waste package quality control, even if the waste will be disposed of in the future. In 2002 the Konrad repository was licensed for the disposal of all types of waste with negligible

  17. Phytoplankton of the North Sea and its dynamics: A review

    Science.gov (United States)

    Reid, P. C.; Lancelot, C.; Gieskes, W. W. C.; Hagmeier, E.; Weichart, G.

    Phytoplankton is the major contributor to algal biomass and primary production of the North Sea, although crops of macroalgae can locally be up to 2000 g C.m -2 along the coast of the U.K. and Norway, and microphytobenthos dominates production in the shallow tidal flat areas bordering the coasts of England, the Netherlands, Germany and Denmark. Data collected since 1932 during the Continuous Plankton Recorder Survey show consistent patterns of geographical, seasonal and annual variation in the distribution of phytoplankton and its major taxonomic components. There is a trend of increased colouration in Recorder silks in the southern North Sea until approximately 1975 since when Colour levels (assumed to be indicative of algal biomass) have declined. In the eutrophic Dutch Wadden Sea the algal crop continued to increase; in Dutch coastal North Sea waters a trend of biomass increase reversed since 1984, apparently due to a reduction in Rhine river outflow. Long-term observations made at Helgoland since the 60's also show trends of increasing nutrients and phytoplankton biomass only to 1984. Adverse effects such as deoxygenation, foam formation and toxin production have been linked to mass concentrations of algae known as blooms. There is no evidence from existing reports for an increase in their frequency, although some years stand out with larger numbers. Occurrence of blooms can partly be explained by hydrographic conditions. More than 30 taxa are recognised as occurring in bloom proportions in the North Sea, approximately one third of which can be toxic. The crop of Bacillariophyceae (diatoms) is not likely to increase with eutrophication due to silicate limitation. An extensive subsurface maximum of armoured dinoflagellates, its abundance gouverned by hydrographic conditions, is the most characteristic feature of the central and northern North Sea in the summer months. Abundance, sometimes dominance, of picoplankton and of species that are not readily detected by

    Since September 1998 the Federal Government formed by a Red/Green Coalition declared its goal: irreversible phase out of nuclear power plants. The first attempt to stop reprocessing as well as the first attempt to change nuclear law failed. The present situation is as follows: existing nuclear power plants operate in a most satisfying way producing 170 TWh/a. i.e. 35% of total production; transport license is not granted; no new NPP is planned, but Germany will participate in the French European Power Reactor (EPR) project. Concerning fast reactors, no industrial activities exist in Germany. There is no intention to build a facility, but Germany participates in the European CAPRA project.

    We present an efficient and flexible alternative method to connect islands and offshore tide gauges with the height system on land. The method uses a regional, high-resolution hydrodynamic model that provides total water levels. From the model, we obtain the differences in mean water level (MWL) between tide gauges at the mainland and at the islands or offshore platforms. Adding them to the MWL relative to the national height system at the mainland's tide gauges realizes a connection of the island and offshore platforms with the height system on the mainland. Numerical results are presented for the connection of the Dutch Wadden islands with the national height system (Normaal Amsterdams Peil, NAP). Several choices of the period over which the MWLs are computed are tested and validated. The best results were obtained when we computed the MWL only over the summer months of our 19-year simulation period. Based on this strategy, the percentage of connections for which the absolute differences between the observation- and model-derived MWL differences are ≤ 1 cm is about 34% (46 out of 135 possible leveling connections). In this case, for each Wadden island we can find several connections that allow the transfer of NAP with (sub-)centimeter accuracy.

    The bacterium Francisella tularensis is known for more than 100 years by now as the etiological agent of the disease tularemia, a zoonotic infection with a worldwide distribution in the Northern Hemisphere. The prevalence of tularemia shows a wide geographic variation, being comparably infrequent in Germany. Tularemia can present itself with multiple clinical manifestations including ulceroglandular, glandular, oropharyngeal, oculoglandular, respiratory and typhoidal forms. Due to the low prevalence and the unspecific symptomatology, a rapid diagnosis and early start of an effective therapy are rarely obtained. Thus, in this article we summarize important aspects concerning etiology, ecology and routes of transmission, recent epidemiologic situation, clinical picture, diagnostics and treatment of tularemia, focusing on the situation in Germany. © Georg Thieme Verlag KG Stuttgart · New York.

  6. Nuclear power in Germany

    Schaefer, A.

    1990-01-01

    I want to give some ideas on the situation of public and utility acceptance of nuclear power in the Federal Republic of Germany and perhaps a little bit on Europe. Let me start with public perception. I think in Germany we have a general trend in the public perception of technology during the last decade that has been investigated in a systematic manner in a recent study. It is clear that the general acceptance of technology decreased substantially during the last twenty years. We can also observe during this time that aspects of the benefits of technology are much less reported in the media, that most reporting by the media now is related to the consequences of technologies, such as negative environmental consequences. hat development has led to a general opposition against new technological projects, in particular unusual and large. That trend is related not only to nuclear power, we see it also for new airports, trains, coal-fired plants. here is almost no new technological project in Germany where there is not very strong opposition against it, at least locally. What is the current public opinion concerning nuclear power? Nuclear power certainly received a big shock after Chernobyl, but actually, about two thirds of the German population wants to keep the operating plants running. Some people want to phase the plants out as they reach the end-of-life, some want to substitute newer nuclear technology, and a smaller part want to increase the use of nuclear power. But only a minority of the German public would really like to abandon nuclear energy

  7. Rewriting Germany's nuclear law

    International Nuclear Information System (INIS)

    Roser, T.

    1992-01-01

    In Germany, the private use of nuclear energy for peaceful uses is strictly regulated by a Nuclear Energy Act. Since its enactment back in 1959, this legislation has been overhauled five times - most recently in 1985. Now Klaus Toepfer, Germany's Federal Minister for the Environment, Protection of Nature, and Nuclear Safety, has set out to revise the Act for the sixth time. The present draft bill is intended to reorganise the back end of the nuclear fuel cycle; eliminate public promotion of nuclear power; clarify points of legal dispute. Of the draft bill's three aims, the last two are more parochial. The real novelty lies in the changes to the rules for the back end of the fuel cycle. First, the Federal Government proposes to abandon the priority given to spent fuel recycling. In future, direct disposal will be an equivalent option, and waste avoidance will have top priority. Intimately linked to the back end proposal is the Government's plan to load on the shoulders of nuclear operators the full responsibility for building and operating repositories for the final disposal of nuclear waste. The third aspect of Government's back end plans concerns decommissioning. At present, operators accumulate provisions over the plant lifetime, which for that purpose is estimated at 19 years. The provisions vary from plant to plant but are generally around DM1 billion and are tax free. Under the proposed regulations, this sum must be available from the first day of operation to cover the case of an early shutdown. In practice, this will increase the initial investment for a nuclear power plant in Germany by 10-20% and so make nuclear power less competitive. (author)

    ABSTRACT Fusarium keratitis is a destructive eye infection that is difficult to treat and results in poor outcome. In tropical and subtropical areas, the infection is relatively common and associated with trauma or chronic eye diseases. However, in recent years, an increased incidence has been reported in temperate climate regions. At the German National Reference Center, we have observed a steady increase in case numbers since 2014. Here, we present the first German case series of eye infections with Fusarium species. We identified Fusarium isolates from the eye or eye-related material from 22 patients in 2014 and 2015. Thirteen isolates belonged to the Fusarium solani species complex (FSSC), 6 isolates belonged to the Fusarium oxysporum species complex (FOSC), and three isolates belonged to the Fusarium fujikuroi species complex (FFSC). FSSC was isolated in 13 of 15 (85%) definite infections and FOSC in 3 of 4 (75%) definite contaminations. Furthermore, diagnosis from contact lens swabs or a culture of contact lens solution turned out to be highly unreliable. FSSC isolates differed from FOSC and FFSC by a distinctly higher MIC for terbinafine. Outcome was often adverse, with 10 patients requiring keratoplasty or enucleation. The use of natamycin as the most effective agent against keratitis caused by filamentous fungi was rare in Germany, possibly due to restricted availability. Keratitis caused by Fusarium spp. (usually FSSC) appears to be a relevant clinical problem in Germany, with the use of contact lenses as the predominant risk factor. Its outcome is often adverse.

After a very difficult and controversial political debate about a probably successful response to AIDS, in the end a political decision was made in favour of the implementation of a long term "social learning strategy". Thus, since then the Bundeszentrale für gesundheitliche Aufklärung (Federal Centre for Health Education, BZgA) has been running the campaign on behalf of the Federal Ministry of Health. The result of this prevention program is a low rate of infections. In Germany there were 2600 newly diagnosed infections in 2005: 59 % in homosexual men, 16 % by heterosexual contacts, 17 % in people from high prevalence countries and 7 % in i.v. drug users. In comparison to the international situation Germany has a relatively low HIV-prevalence even nowadays. However, Germany has also been confronted with an increasing number of newly diagnosed infections in the last few years. When the prevention program was started it was very important to build new structures for a successful implementation of the campaign. That meant for instance to build up an effective infrastructure for cooperation between the governmental and the nongovernmental sector, including organising the coordinated action among the partners at the federal, regional and local levels. Likewise, international networking was of great importance. A key element, relevant for the success of the campaign was the close cooperation at the federal level between the BZgA and the Deutsche AIDS Hilfe (German AIDS Help, DAH), to combine the highreach intervention in low-prevalence populations with intensive interventions for high prevalence groups. An effective national AIDS prevention campaign must reach the whole population; inform the public about the main risks of infection, about methods of protection and about what is not infectious. Moreover groups with a higher level of risk of

  20. West Germany's nuclear dilemma

    International Nuclear Information System (INIS)

    Dangelmayer, D.

    1978-01-01

    The US 1978 Nuclear Non-Proliferation Act legislated the embargo of enriched uranium supplies from that country to any other country which would not agree to tighter restrictions on a wide variety of their nuclear activities, including the reprocessing of spent uranium to provide separated plutonium. This has resulted in a three month supply cut-off to the EEC countries. However the EEC is now willing to renegotiate supply contracts with the US to accord with the tighter safeguards set down in the Act. Effectively both sides now have an 18 month breathing space for them to seek a compromise on the non-proliferation question. The effect of these strategies on West Germany's energy policy, which seeks to become increasingly energy self-sufficient through the use of nuclear fuel reprocessing and the fast reactor, is discussed.

  1. Environmental Foundations in Germany

    2015-05-01

    Full Text Available Foundations in Germany were examined in the context of environmental issues. Data from environmental foundations show that there is huge difference between private and public foundations concerning financial settings. Furthermore, environment is often not the only objective and sometimes not even processed. Our analysis shows that there are different types of foundations with regard to environmental scopes and activities. Although “attractive topics” such as biodiversity and landscape conservation seem to be more important to foundations, less visible topics such as pollution prevention remain merely a “blind spot.” Together, these findings suggest that there is only a limited potential of private foundations compared with public foundations. Nevertheless, there might be an impact on environmental awareness and local sustainability.

  2. Nuclear power in Germany

    1985-01-01

    On the occasion of the retirement of the Editor-in-chief of 'atomwirtschaft', the author gave a keynote speech on the development of nuclear power in the Federal Republic of Germany at the headquarters of the Handelsblatt Verlag in Duesseldorf on October 30, 1984. He subdivided the period under discussion into five phases, the first of which comprises the 'founding years' of 1955 to 1960. This was the time when activities in nuclear research and nuclear technology in Germany, which were permitted again in mid-1955, began with the establishment of the national research centers, the first Atomic Power Program, the promulgation of the Atomic Energy Act, the foundation of government organizations, including the Federal Ministry for Atomic Energy, etc. In the second phase, between 1960 and 1970, a solid foundation was laid for the industrial peaceful uses of nuclear power in the construction of the first LWR experimental nuclear power stations, the first successful export contracts, the beginnings of the first nuclear fuel cycle plants, such as the WAK reprocessing plant, the Asse experimental repository, the Almelo agreement on centrifuge enrichment. The third phase, between 1970 and 1975, was a period of euphoria, full of programs and forecasts of a tremendous boom in nuclear generating capacities, which were further enhanced by the 1973 oil squeeze. In 1973 and 1974, construction permits for ten nuclear power plants were applied for. The fourth phase, between 1975 and 1980, became a period of crisis. The fifth phase, the eighties, give rise to hope for a return to reason. (orig./UA) [de

  3. Visual effects of test drilling for natural gas in the Waddenzee and the North Sea coastal area

    The potential hindrance of the view, caused by offshore platforms, has been investigated as part of the environmental impact reports for test drilling for natural gas in the North Sea area, on the island Ameland and in the Wadden Sea. The hindrance is determined by calculating the weighed numbers of inhabitants and vacationers within 10 km of 26 drilling sites, divided over 12 drilling areas. For each drilling area the preferred location was determined. The hindrance of the view is the lowest when drilling tests are carried out in the winter. Also digital photo paste-ups were made by which it can be shown how drilling installations look like in a landscape. Finally, measures are given by which the visual effects of drilling installations and burn off can be reduced. 34 figs., 33 tabs., 2 appendices, 35 refs

  4. Annual mean sea level and its sensitivity to wind climate

    Gerkema, Theo; Duran Matute, Matias

    2017-04-01

    Changes in relative mean sea level affect coastal areas in various ways, such as the risk of flooding, the evolution of barrier island systems, or the development of salt marshes. Long-term trends in these changes are partly masked by variability on shorter time scales. Some of this variability, for instance due to wind waves and tides (with the exception of long-period tides), is easily averaged out. In contrast, inter-annual variability is found to be irregular and large, of the order of several decimeters, as is evident from tide gauge records. This is why the climatic trend, typically of a few millimeters per year, can only be reliably identified by examining a record that is long enough to outweigh the inter-annual and decadal variabilities. In this presentation we examine the relation between the annual wind conditions from meteorological records and annual mean sea level along the Dutch coast. To do this, we need reliable and consistent long-term wind records. Some wind records from weather stations in the Netherlands date back to the 19th century, but they are unsuitable for trend analysis because of changes in location, height, surroundings, instrument type or protocol. For this reason, we will use only more recent, homogeneous wind records, from the past two decades. The question then is whether such a relatively short record is sufficient to find a convincing relation with annual mean sea level. It is the purpose of this work to demonstrate that the answer is positive and to suggest methods to find and exploit such a relation. We find that at the Dutch coast, southwesterly winds are dominant in the wind climate, but the west-east direction stands out as having the highest correlation with annual mean sea level. For different stations in the Dutch Wadden Sea and along the coast, we find a qualitatively similar pattern, although the precise values of the correlations vary. The inter-annual variability of mean sea level can already be largely explained by

    2016-05-01

    Full Text Available This essay investigates the enduring fascination with the sixteenth President of the United States in Germany. In general, his legacy and its evaluation changed in relation to the determinate historical contexts, beginning with the monarchial system, extending through the Weimar Republic, the Third Reich, and now the Federal Republic of Germany. Certain social and political individuals/groups in Germany used the image and iconography of Lincoln as a projection screen to support their own political objectives. Although there were always multiple layers of Lincoln representations in Germany, the dominant images were: the national unifier, the libertarian universalist, the emancipator, the defender of moral values, the modernizer, the democrat who used the power of the democratic state, the egalitarian self-made man from humble origins, and the defender of social justice and workingmen’s rights.

    Molly, J.P.

    1994-01-01

    End of June 1994 429 MW in about 2100 wind energy converters (WECs) have been installed in Germany, able to produce 1.1% of the electrical energy demand of the five German coastal states Lower Saxony, Bremen, Hamburg, Schleswig-Holstein and Mecklenburg-Vorpommern. Determining factor for the again increased installation rate, compared with 1993, is the new 500/600-kW-class which now dominates the market. Dramatically reduced WEC prices during the last two years now allow an economic operation in good wind speed regions even without any subsidy. The goal to reach a total of 2000 MW WEC installations in the year 2000 is suddenly near at hand. In the course of the next seven years an installation rate of 250 MW/year will be necessary, a value which could be reached already in 1994. Nevertheless, there still is a long way to go, if the 2000 MW shall be achieved in the year 2000. New obstacles have arisen due to the increasingly restrictive handling of WEC site permission by conservationists, often in discrepancy with the generally recognized global ideas of the eco-organizations. After more than two years of experience, the WEC quality dependent subsidy as applied in Lower Saxony proofs to be a very effective stimulation for the technical development. WECs are now optimized for maximum energy production and minimum noise emission. The new 500/600-kW class is only half as noisy as could be expected from an extrapolation based on smaller WEC units. The energy cost reduction with the size of the WECs is still going on, indicating that the new Megawatt-WECs in development can offer again an economic advantage for the operator. (orig.)

  13. Arthroplasty register for Germany

    Full Text Available Scientific background: The annual number of joint replacement operations in Germany is high. The introduction of an arthroplasty register promises an important contribution to the improvement of the quality of patient’s care. Research questions: The presented report addresses the questions on organization and functioning, benefits and cost-benefits as well as on legal, ethical and social aspects of the arthroplasty registers. Methods: A systematic literature search was conducted in September 2008 in the medical databases MEDLINE, EMBASE etc. and was complemented with a hand search. Documents describing arthroplasty registers and/or their relevance as well as papers on legal, ethical and social aspects of such registers were included in the evaluation. The most important information was extracted and analysed. Results: Data concerning 30 arthroplasty registers in 19 countries as well as one international arthroplasty register were identified. Most of the arthroplasty registers are maintained by national orthopedic societies, others by health authorities or by their cooperation. Mostly, registries are financially supported by governments and rarely by other sources.The participation of the orthopedists in the data collection process of the arthroplasty registry is voluntary in most countries. The consent of the patients is usually required. The unique patient identification is ensured in nearly all registers.Each data set consists of patient and clinic identification numbers, data on diagnosis, the performed intervention, the operation date and implanted prostheses. The use of clinical scores, patient-reported questionnaires and radiological documentation is rare. Methods for data documentation and transfer are paper form, electronic entry as well as scanning of the data using bar codes. The data are mostly being checked for their completeness and validity. Most registers offer results of the data evaluation to the treating orthopedists and

    Transport and deposition of atmospheric lead over the coastal zone of Northern Germany are investigated. It is shown that marked differences in the impact of the ecologically valuable wadden sea areas can occur between summer and winter time. Due to the formation of sea breeze systems in summer the coastal zone is likely to be less stressed than in winter when the pollutant is confined to a shallow layer above ground. (orig.) 10 refs.

    The ongoing daily sampling programme of the fish fauna in the Dutch Wadden Sea using fixed gear was analysed for the years 1960-2011. Spring sampling caught immigrating fish from the coastal zone and autumn samples reflected emigration of young-of-the-year. In total 82 fish species were caught with no clear trend in biodiversity. In both spring and autumn total daily catch fluctuated and peaked in the late 1970s. From 1980 to the present catches of both pelagic and demersal species showed a 10-fold decrease in total biomass. Mean individual biomass decreased in spring between 1980 and the present from about 150 to 20 g wet weight. No trend was found in autumn mean individual biomass which fluctuated around 20 g wet weight. The trophic structure remained constant for both the demersal and benthopelagic fish fauna from 1980 to 2011, whilst the trophic position of pelagic fish in spring fell from about 3.9 to 3.1. Min/max auto-correlation factor analysis showed similar trends in spring and autumn species biomass time series: the first axis represented a decrease from the 1960s followed by stabilization from the mid-1990s. The second trend showed an increase with a maximum around 1980 followed by a steady decrease in spring and a decrease and stabilization from 2000 in autumn. It is argued that the most likely explanatory variables are a combination of external factors: increased water temperature, habitat destruction in the coastal zone (sand dredging and beach nourishment, fishing) and increased predation by top predators for the first trend, and large-scale hydrodynamic circulation for the second trend. We conclude that both the trophic structure of the coastal zone fauna and the nursery function of the Wadden Sea have been reduced since the 1980s. Our findings corroborate that ecological change in coastal ecosystems has not only occurred in the past but still continues.

    Quantitative fire risk assessment can serve as an additional tool to assess the safety level of a nuclear power plant (NPP) and to set priorities for fire protection improvement measures. The recommended approach to be applied within periodic safety reviews of NPPs in Germany starts with a screening process providing critical fire zones in which a fully developed fire has the potential to both cause an initiating event and impair the function of at least one component or system critical to safety. The second step is to perform a quantitative analysis using a standard event tree has been developed with elements for fire initiation, ventilation of the room, fire detection, fire suppression, and fire propagation. In a final step, the fire induced frequency of initiating events, the main contributors and the calculated hazard state frequency for the fire event are determined. Results of the first quantitative fire risk studies performed in Germany are reported. (author)

  5. Energy supply in East Germany

    Energy Technology Data Exchange (ETDEWEB)

    Shimoyama, Tsutomu

    1988-07-10

    East Germany has abundant brown coal, about 90.4% of primary energy production in 1986. The high dependence upon brown coal has been established since its reevaluation in 1980 and the production is reaching a peak. Its share in power generation is also as high as 83.3% in the year. Therefore, the energy sufficiency of East Germany is about 80%. Problems are arising, however, in deterioration of excavation conditions and coal quality. Domestic energy resources such as the uranium and natural gas are also used to the maximum extent. The nuclear power has about 10% of share in the power generation. The share expansion policy is seemingly maintained even after the accident of Chernoble. Exploration, excavation and reprocessing of the uranium are conducted under the leadership of USSR. The country depends upon the oil in a very low level, less than 1%, as a result of the energy conservation policy in 1980's. (1 fig, 5 tabs)

    Germany has decided to phase out nuclear power by 2022 but it wants also to get rid of fossil energies by 2050. Those ambitious goals imply to be able to cut by half the demand for primary energy by 2050 which will be only possible if the need for building heating is cut by 80%, the constraint on transport is less important: one million of electrical vehicles will have to be on the road by 2020 and 3 millions 10 years later. In 2012 the production of electricity was made mainly from coal (44.7%), renewable energies (21.9%), nuclear energy (16%), natural gas (11.3%) and other energies (fuel...) (6.1%). Today the renewable energy sector is a major industrial sector in Germany, it represents about 382000 jobs directly or indirectly, it means more than the sector of conventional energies. (A.C.)

    This paper presents first empirical evidence on international student migration to Germany. I use a novel approach that analyzes student mobility using an augmented gravity equation and find evidence of strong network effects and of the importance of distance - results familiar from the empirical migration literature. However, the importance of disposable income in the home country does not seem to be too big for students, while the fact of being a politically unfree country decreases migrati...

  8. ARCHAEOLOGICAL SURVEYS ON THE GERMAN NORTH SEA COAST USING HIGH-RESOLUTION SYNTHETIC APERTURE RADAR DATA

    Full Text Available We show that high-resolution space-borne Synthetic Aperture Radar (SAR imagery with pixel sizes well below 1 m2 can be used to complement archaeological surveys in areas that are difficult to access. After major storm surges in the 14th and 17th centuries, vast areas on the German North Sea coast were lost to the sea. Areas of former settlements and historical land use were buried under sediments for centuries, but when the surface layer is driven away under the permanent action of wind, currents, and waves, they appear again on the Wadden Sea surface. However, the frequent flooding and erosion of the intertidal flats make any archaeological monitoring a difficult task, so that remote sensing techniques appear to be an efficient and cost-effective instrument for any archaeological surveillance of that area. Space-borne SAR images clearly show remnants of farmhouse foundations and of former systems of ditches, dating back to the 14th and to the 16th/17th centuries. In particular, the very high-resolution acquisition (staring spotlight mode of the German TerraSAR/ TanDEM-X satellites allows for the detection of various kinds of residuals of historical land use with high precision. In addition, we also investigate the capability of SARs working at lower microwave frequencies (on Radarsat-2 to complement our archaeological survey of historical cultural traces, some of which have been unknown so far.

    The spatial and temporal distributions of chromophoric dissolved organic matter (CDOM) and dissolved organic carbon (DOC) was studied in the East-Frisian Wadden Sea (Southern North Sea) during several cruises between 2002 and 2005. The spatial distribution of CDOM in the German Bight shows a strong gradient towards the coast. Tidal and seasonal variations of dissolved organic matter (DOM) identify freshwater discharge via flood-gates at the coastline and pore water efflux from tidal flat sediments as the most important CDOM sources within the backbarrier area of the Island of Spiekeroog. However, the amount and pattern of CDOM and DOC is strongly affected by various parameters, e.g. changes in the amount of terrestrial run-off, precipitation, evaporation, biological activity and photooxidation. A decoupling of CDOM and DOC, especially during periods of pronounced biological activity (algae blooms and microbial activity), is observed in spring and especially in summer. Mixing of the endmembers freshwater, pore water, and open sea water results in the formation of a coastal transition zone. Whilst an almost conservative behaviour during mixing is observed in winter, summer data point towards non-conservative mixing.

  10. Radioactive waste in Federal Germany

    1988-01-01

    The Physikalisch-Technische Bundesanstalt (PTB) is responsible for the long-term storage and disposal of radioactive waste according to the Federal Atomic Energy Act. On behalf of the Federal Minister of the Environment, Nature Conservation and Nuclear Safety, since 1985, the PTB has been carrying out annual inquiries into the amounts of radioactive waste produced in the Federal Republic of Germany. Within the scope of this inquiry performed for the preceding year, the amounts of unconditioned and conditioned waste are compiled on a producer- and plant-specific basis. On the basis of the inquiry for 1986 and of data presented to the PTB by the waste producers, future amounts of radioactive waste have been estimated up to the year 2000. The result of this forecast is presented. In the Federal Republic of Germany two sites are under consideration for disposal of radioactive waste. In the abandoned Konrad iron mine in Salzgitter-Bleckenstedt it is intended to dispose of such radioactive waste which has a negligible thermal influence upon the host rock. The Gorleben salt dome is being investigated for its suitability for the disposal of all kinds of solid and solidified radioactive wastes, especially of heat-generating waste. Comparing the estimated amount of radioactive wastes with the capacity of both repositories it may be concluded that the Konrad and Gorleben repositories will provide sufficient capacity to ensure the disposal of all kinds of radioactive waste on a long-term basis in the Federal Republic of Germany. 1 fig., 2 tabs

  11. Undergraduate medical education in Germany

    2009-04-01

    Full Text Available The purpose of this article is to give international readers an overview of the organisation, structure and curriculum, together with important advances and problems, of undergraduate medical education in Germany. Interest in medical education in Germany has been relatively low but has gained momentum with the new "Regulation of the Licensing of Doctors" which came into effect in 2003. Medical education had required substantial reform, particularly with respect to improving the links between theoretical and clinical teaching and the extension of interdisciplinary and topic-related instruction. It takes six years and three months to complete the curriculum and training is divided into three sections: basic science (2 years, clinical science (3 years and final clinical year. While the reorganisation of graduate medical education required by the new "Regulation of the Licensing of Doctors" has stimulated multiple excellent teaching projects, there is evidence that some of the stipulated changes have not been implemented. Indeed, whether the medical schools have complied with this regulation and its overall success remains to be assessed systematically. Mandatory external accreditation and periodic reaccreditation of medical faculties need to be established in Germany.

    Full text: The primary energy consumption in Germany in 2005 was about 492.6 MtSKE in total. The distribution on the main energy sources is: mineral oil: 36.4%, natural gas 22.4%, black coal 13.5%, brown coal 11.4%, nuclear energy 12.6%, water and wind 1.2%, others 2.5%. The net electricity production in Germany in 2005 was about 495.9 billion kWh. The distribution is: nuclear energy 32%, lignite coal 28.9%, black coal 23.1%, oil 0.2%, natural gas 9.1%, water 4.7%, others (being biomass, photovoltaics, wind) 2.0%. In 2005, 18 nuclear power plants were in operation in Germany. In May 2005 the KWO Obrigheim was closed due to the new Atomic law which fixes the phase out of nuclear power production. The net installed nuclear power was 20.7GWel, the net nuclear electricity production was 163TWh, the time availability was 88%. Nuclear makes up for about 50% of the base-load electricity production in Germany. In absolute numbers, Germany is number 5 in nuclear electricity production. Among the top ten nuclear power plants world-wide, in 2005 there were 7 German plants including the plant with the highest amount of electricity produced, being NPP Brokdorf with 1440MWel and 11.98TWhel. The net electricity output of the nuclear power plants is constantly increasing due to power upgrading and higher time availabilities. As for the renewable energies, there is no significant absolute increase except for wind. About 50% of the government support for renewable energies from the Environmental Ministry goes to photovoltaics. The Helmholtz-Gemeinschaft (HGF), summarising 15 national research centres, 24.000 employees and a yearly budget of about 2,1 billion Euro is the largest research organisation in Germany. The HGF identifies and works on complex and urgent questions of society, science and economy, especially concentrating on systems of high complexity. There are six research areas, being energy, earth and environment, health, key technologies, structure of matter, traffic and

    2016-01-01

    As Germany is already one of the European countries where electricity prices are the highest for households (twice more than in France), the author comments the past evolution of these prices and shows that they will probably increase again in 2017 to finance energy transition. This increase is notably due to higher taxes (a comparison with the French CSPE tax is presented and commented), and to a costly grid renewal. As the energy transition appears to be very expensive (about 500 billions euros by 2025), the cost-benefit rate of the German energy transition is disastrous and the de-carbonation of the electricity sector does not progress

  17. Recycling of plastics in Germany

    Thienen, N. von; Patel, M.

    1999-01-01

    This article deals with the waste management of post-consumer plastics in Germany and its potential to save fossil fuels and reduce CO 2 emissions. Since most experience is available for packaging, the paper first gives an overview of the legislative background and the material flows for this sector. Then recycling and recovery processes for plastics waste from all sectors are assessed in terms of their contribution to energy saving and CO 2 abatement. Practically all the options studied show a better performance than waste treatment in an average incinerator which has been chosen as the reference case. High ecological benefits can be achieved by mechanical recycling if virgin polymers are substituted. The paper then presents different scenarios for managing plastic waste in Germany in 1995: considerable savings can be made by strongly enhancing the efficiency of waste incinerators. Under these conditions the distribution of plastics waste among mechanical recycling, feedstock recycling and energy recovery has a comparatively mall impact on the overall results. The maximum savings amount to 74 PJ of energy, i.e, 9% of the chemical sector energy demand in 1995 and 7.0 Mt CO 2 , representing 13% of the sector's emissions. The assessment does not support a general recommendation of energy recovery due to the large difference between the German average and the best available municipal waste-to-energy facilities and also due to new technological developments in the field of mechanical recycling

    Cosmic radiation at high altitudes, especially high energetic neutrons, significantly increases exposure to man. Pilots and flight attendants may receive annual effective doses comparable to doses received in occupations, in which ionising radiation is used or radioactive sources are handled. For this reason, the European Council Directive 96/29 EURATOM requires that air-crew members also be monitored for radiation protection. Flight personnel, receiving an effective dose from cosmic radiation of more than 1 mSv per year are subject to monitoring i.e. radiation exposure has to be assessed, limited and minimized. As the physical conditions causing cosmic radiation doses are well established, it is possible to calculate the expected radiation dose with sufficient accuracy. Several codes for this purpose are available. Since August 2003, the operators of airlines in Germany are obliged to assess the doses of their air crew personnel from cosmic radiation exposure and to minimise radiation exposure by means of appropriate work schedules, flight routes and flight profiles. Approx. 31 000 persons of 45 airlines are monitored by the German Radiation Protection Register. Gender, age and 3 different occupational categories are used to characterise different groups and their doses. The presentation will give an overview about the legislation and organisation of air crew monitoring in Germany and will show detailed statistical results from the first year of monitoring.

  19. Financing long term liabilities (Germany)

    International Nuclear Information System (INIS)

    2003-01-01

    In Germany the basis for the management of radioactive residues is the polluter-pays principle. All steps of treatment of radioactive waste arising from operation, decommissioning and dismantling including conditioning, interim storage and disposal of radioactive waste have to be financed by the waste producers. The waste producers are responsible for the harmless recycling of the residues or for their orderly management as radioactive waste. The Federal Government is responsible for establishing disposal facilities. Accordingly the waste producers are constructing and operating facilities in which the radioactive residues can be treated and stored until their disposal. As far as the radioactive waste cannot be stored by the producer, waste originating from research, medicine and industry can be stored in surface storage facilities of the federal states. Spent fuel from German NPPs is partly reprocessed in France and UK. The rest has to be disposed off directly in deep geologic formations. Until a repository for spent fuel is available in Germany spent fuel will be stored in interim storage facilities on the sites of the NPPs. The storage will take place in casks in a dry way. In exceptional cases, if the storage at a NPP site is not possible, there are two central storages at Ahaus and Gorleben which are in operation and can be made available as reserve. Radioactive waste returning from the reprocessing of German spent fuel in France and UK is stored in the Gorleben central storage. The Federal Government is aiming to establish a repository in deep geological formations about the year 2030 which shall be available for all types and quantities of radioactive waste. The necessary expenses for the planning and construction of radioactive waste disposal facilities are initially carried by the Federal Government. The Government recovers the costs by contributions or advance payments from the waste producers. The use of storage and disposal facilities is financed by

    Southeast Asian Seas (SEAS) span the largest archipelago in the global ocean and provide a complex oceanic pathway connecting the Pacific and Indian Oceans. The SEAS regional sea level trends are some of the highest observed in the modern satellite altimeter record that now spans almost two decades. Initial comparisons of global sea level reconstructions find that 17 year sea level trends over the past 60 years exhibit good agreement in areas and at times of strong signal to noise associated decadal variability forced by low frequency variations in Pacific trade winds. The SEAS region exhibits sea level trends that vary dramatically over the studied time period. This historical variation suggests that the strong regional sea level trends observed during the modern satellite altimeter record will abate as trade winds fluctuate on decadal and longer time scales. Furthermore, after removing the contribution of the Pacific Decadal Oscillation (PDO) to sea level trends in the past twenty years, the rate of sea level rise is greatly reduced in the SEAS region. As a result of the influence of the PDO, the SEAS regional sea level trends during 2010s and 2020s are likely to be less than the global mean sea level (GMSL) trend if the observed oscillations in wind forcing and sea level persist. Nevertheless, long-term sea level trends in the SEAS will continue to be affected by GMSL rise occurring now and in the future.

    Introduction  Efficient neurosurgical training is of paramount importance to provide continuing high-quality medical care to patients. In this era of law-enforced working hour restrictions, however, maintaining high-quality training can be a challenge and requires some restructuring. We evaluated the current status of resident training in Germany. Methods  An electronic survey was sent to European neurosurgical trainees between June 2014 and March 2015. The responses of German trainees were compared with those of trainees from other European countries. Logistic regression analysis was performed to assess the effect size of the relationship between a trainee being from Germany and the outcome (e.g., satisfaction, working time). Results  Of 532 responses, 95 were from German trainees (17.8%). In a multivariate analysis corrected for baseline group differences, German trainees were 29% as likely as non-German trainees to be satisfied with clinical lectures given at their teaching facility (odds ratio [OR]: 0.29; 95% confidence interval [CI]: 0.18-0.49; p  hours as requested from the European Working Time Directive 2003/88/EC, and in an international comparison, German trainees were twice as likely to work > 50 hours per week (OR: 2.13; 95% CI, 1.25-3.61; p  = 0.005). This working time, however, is less spent in the operating suite (OR: 0.26; 95% CI, 0.11-0.59; p  = 0.001) and more doing administrative work (OR: 1.83; 95% CI, 1.13-2.96; p  = 0.015). Conclusion  Some theoretical and practical aspects of neurosurgical training are superior, but a considerable proportion of relevant aspects are inferior in Germany compared with other European countries. The present analyses provide the opportunity for a critical review of the local conditions in German training facilities. Georg Thieme Verlag KG Stuttgart · New York.

    Politicians and scholars alike praise the significant benefits associated with employee share ownership (ESO). However, little is known about the concrete motives of firms to provide ESO to their employees. In particular, it is unknown how these motives correlate with firms’ contexts. Drawing...... on an institutional theoretical framework, this article examines what aims firms pursue through the provision of ESO. The data originate from a survey of firms in Germany. The cluster analytic findings indicate distinctive patterns of relationships between aims and firm characteristics. Aims related to employee...... performance are most important to foreign-owned firms, financial aims are most important to non-public small and medium-sized firms and aims related to corporate image are most important to big firms and to firms that do not provide profit sharing. Aims related to employee attraction and retention are almost...

    2013-01-01

    Full Text Available The Energy-CSOP facilitates broad equity participation of citizens without assets or savings in a regulated public energy utility. As the CSOP is designed for regulated markets with guaranteed prices, regulated market access and long-term relationships between producer and consumer, the energy market is predestined. A CSOP trust can be set up for a renewable energy plant (e.g., a biogas reactor, a solar panel, a windmill or a geothermic drill. European states have set an ambitious target to reach 20% share of energy from renewable sources by 2020. Germany as Europe’s green energy leader could become a pioneer in CSOP implementation. Small communities in Europe would benefit from the increased share of renewable energy resources.

    Under the influence of the polarization between belief in progress, on the one hand, and the moral rigorism of our society, on the other hand, the risks of modern large technical systems have helped the highest level of technical safety to be attained in Germany. It has been reached especially by opting for maximum quality, maximum utility and reliability, complete documentation, continuous in-service checks during operation and, last but not least, by including man and human fallibility. Our concern should be that this strategy pursued in the Western industrialized countries becomes the rule, at least in its main characteristics, also in the Eastern countries. The hazards associated with reactors in Eastern countries affect us all, and it is especially the safety of those reactors which is causing concern. The experience accumulated with the 417 nuclear power plants now in operation, especially the incidents and accidents, shows that hazard potential management is admissible only with a highly developed safety strategy.

    Ten harbour seals (Phoca vitulina) caught on the Danish Wadden Sea island Roemoe were equipped with satellite linked time depth recorders. The animals were caught on three separate occasions (Jan. 4th, Feb. 18th and May 6th, 2002). The transmitters worked between 49 and 100 days, relaying positional and dive information back via the ARGOS satellite service until beginning of July. Background for the studies is the construction of the Worlds largest off shore wind farm on Horns Reef. Based on previous studies using VHF-transmitters, it was expected that the seals would spend considerable time on Horns Reef. The VHF-telemetry studies showed that the preferred direction for seals leaving the Danish Wadden Sea is NW from Graedyb tidal area outside Esbjerg, the direction directly towards the wind farm area. The previously used VHF-transmitters had a limited detection range and it was decided to equip a number of seals from the same area as before with satellite transmitters. This allows for positioning of the seals in the entire North Sea as well as providing dive summary information, as a transmitter with a depth transducer was chosen for the study. Positional information revealed that animals move about more extensively than previously believed. Substantial variation between animals was observed and each seal seemed to have adopted its own foraging strategy. Some animals travelled to the centre of the North Sea on foraging trips and spent considerable time close to the bottom at 30-70 meters depth. Other seals remained in the German Bight and yet others spent considerable time on and around Horns Reef. The area of Horns reef wind farm constitutes a negligible fraction of the total area visited by the tagged seals. The reef as a whole however, appears to be important to the seals both for foraging and as transit area to other feeding grounds further off shore. The resolution in positional information is not sufficiently high to allow for a detailed study of the effects

    During 2013, Arctic sea ice extent remained well below normal, but the September 2013 minimum extent was substantially higher than the record-breaking minimum in 2012. Nonetheless, the minimum was still much lower than normal and the long-term trend Arctic September extent is -13.7 per decade relative to the 1981-2010 average. The less extreme conditions this year compared to 2012 were due to cooler temperatures and wind patterns that favored retention of ice through the summer. Sea ice thickness and volume remained near record-low levels, though indications are of slightly thicker ice compared to the record low of 2012.

    2010-01-01

    Following the requirements of the European Directive 2001/42/EC on strategic environmental assessment (SEA) and the Protocol on Strategic Environmental Assessment (Kiev, 2003) to the Convention on Environmental Impact Assessment in a Transboundary Context (Espoo, 1991), health is one of the aspects to be considered in SEA. In this paper, results of an evaluation of eight SEAs from Austria, the Czech Republic, Germany, the Netherlands and the United Kingdom (England and Wales) regarding the consideration of health are presented. This includes SEAs for five spatial plans, as well as one SEA for each, a transport, a waste management and an economic development plan. It is found that while all SEAs cover important physical and natural aspects that are related to health, social and behavioural aspects are considered to a much smaller extent. Based on the results, facilitating factors and barriers for health inclusive SEA are identified. Overall, good baseline data can be seen as an important starting point for effective health inclusive SEA, while an effective monitoring system is crucial for effective implementation of the measures and recommendations brought forward in health inclusive SEA. Crucially, health authorities/health experts need to engage more with SEA, as this provides a key platform for cross sectoral dialogue on a range of issues. SEA presents the health sector with an opportunity to influence the policy and decision-making process to improve people's health and well-being.

  13. An Earth System Science Program for the Baltic Sea Region

    From Russia in the east to Sweden, Denmark, and Germany in the west, reaching south to the tips of the Czech Republic, Slovakia, and Ukraine, the Baltic Sea watershed drains nearly 20% of Europe (see Figure 1). In the highly populated south, the temperate climate hosts intensive agriculture and industry. In the north, the landscape is boreal and rural. In the Baltic Sea itself, complex bathymetry and stratification patterns as well as extended hypoxic and anoxic deep waters add to the diversity. Yet in recent history, the differences across the Baltic Sea region have been more than physical: In the mid-20th century, the watershed was split in two.

    Record year 2014. In Germany, the expansion figures attained were so high on land and at sea that the overall new installation figure of 5,188 MW surpassed the previous maximum (from 2002) by more than 60%. With an overall capacity of 39,259 MW, for the first time, wind energy in Germany covers 9.7% of gross power consumption. On the global scale a capacity of more than 51,000 MW has been added - another record high for wind energy installations. Power mix. At 161 TWh, renewable energies in Germany covered 27.8% of gross power consumption and provided for the first time more energy than any other energy source. Coming into force of the new REA in August 2014, modified support schemes caused the expansion of biogas plants and large-scale PV installations to falter. The record expansion seen for wind energy can be interpreted as a pull-forward effect due to the tender procedures coming into force in 2017. Grid integration. Loss of production caused by feed-in management measures rose by 44% to 555 GWh as compared to 2012. Wind turbines were affected in 87% of cases but the impact on PV installations is increasing. Power generation must be more flexible and grids expanded to limit loss of production. Of the 23 expansion projects (1,887 km) in the Electricity Grid Expansion Act, just a quarter of them had been realized by the end of 2014 (463 km). In the preliminary analysis results for the 2014 grid development plan, the extent of grid upgrading and conversion was 3050 km. Offshore, the HelWin 1 grid link with a capacity of 580 MW went online. SylWin 1 and BorWin 2, with a total capacity of 1660 MW, are currently being tested in a trial. In the preliminary analysis results for the 2014 offshore grid development plan, grid connections having an overall capacity of 10.3 GW are planned. Onshore. 2014 saw a total of 44 different turbine types installed in Germany. For the first time, virtually the same number of turbines were added in the 3-4 MW class, as in the 2-3 MW

    Southeast Asian seas span the largest archipelago in the global ocean and provide a complex oceanic pathway connecting the Pacific and Indian oceans. The Southeast Asian sea regional sea level trends are some of the highest observed in the modern satellite altimeter record that now spans almost 2 decades. Initial comparisons of global sea level reconstructions find that 17-year sea level trends over the past 60 years exhibit good agreement with decadal variability associated with the Pacific Decadal Oscillation and related fluctuations of trade winds in the region. The Southeast Asian sea region exhibits sea level trends that vary dramatically over the studied time period. This historical variation suggests that the strong regional sea level trends observed during the modern satellite altimeter record will abate as trade winds fluctuate on decadal and longer timescales. Furthermore, after removing the contribution of the Pacific Decadal Oscillation (PDO) to sea level trends in the past 20 years, the rate of sea level rise is greatly reduced in the Southeast Asian sea region. As a result of the influence of the PDO, the Southeast Asian sea regional sea level trends during the 2010s and 2020s are likely to be less than the global mean sea level (GMSL) trend if the observed oscillations in wind forcing and sea level persist. Nevertheless, long-term sea level trends in the Southeast Asian seas will continue to be affected by GMSL rise occurring now and in the future.

    Almost a quarter of a century after the fall of the Wall, there are still more women in employment in eastern Germany than in the west. Although the disparity is marginal now, the two regions started from dramatically different levels. In 1991, immediately after reunification, the employment rate for women in western Germany was 54.6 percent, but since then it has increased year on year, reaching 67.5 percent in 2012. In eastern Germany, female employment initially plummeted after the fall of...

  19. Electricity prices differences between France and Germany

    Hensing, I.; Nolden, A.; Riechmann, Ch.; Schulz, W.

    1998-01-01

    High electricity prices in Germany especially as compared to France have played an important role in the electricity liberalization debate in Germany. The price differences can largely be explained by cost differences in electricity generation, the electricity grids, personnel cost and local taxes. Further analysis suggests that efficiency improvements upon market liberalization will only partly remove these price and cost differentials. Parts of the cost differentials are attributable to politically-motivated regulations and the (future) regulation of network functions. This implies that Germany can only expect to arrive at internationally comparable electricity prices if it advances with a reform of political and monopoly regulations alongside liberalizing electricity generation and trade.

    Demographic change (ageing populations and falling birth rates) affects all industrialised nations, including Germany. Traditionally, the problems associated with managing numbers of older workers were mitigated by the Altersteilzeitgesetz in Germany. Under this law, firms were offered financial support by the government to offer early retirement (Müller-Camen et al. 2009). As these provisions came to an end in 2010, the need to find alternative solutions to displacing older workers, as well ...

    After a downward trend of many years Germany's energy-related CO 2 emissions have risen again slightly over the past two years. This increase has prompted the federal government to initiate a new climate protection action campaign. After almost 30 years of experience in the field of climate protection policy there is every reason for Germany to be more consistent in using its political scope to act on the unrestrained increase in global greenhouse gas emissions.

    In recent years the topic of dental tourism has increasingly come into focus of dentists and patients. In the present study an attempt was made to find out, why patients from a restricted region travel to Germany for dental care. In five German dental clinics located in the border area between Switzerland and Germany, 272 women and 236 men ranging in age from 5 to 94 years, who had undergone at least one dental treatment in Germany, were questioned concerning the reasons for their visits. The interviews took place within a period of 6 months and relied on a questionnaire to collect data regarding sociodemographic features and patient behavior. In comparison to residents of Germany, patients residing in Switzerland took on considerably longer travel distances for the dental visit, in some cases more than 50km (9.7%). For patients residing in Switzerland the technical equipment of the practice was more important (pSwitzerland (95.6%) confirmed that dental treatments in Germany were cheaper and that additional family members also came to Germany for dental care (65.0%).

    The Nuclear Technology Conference organized annually by the Deutsches Atomforum (DAtF) e.V. and the Kerntechnische Gesellschaft (KTG) e.V. was held in Aachen on May 13-15, 1997. Approximately 1000 participants from seventeen countries met to exchange information with experts from industry, research, science, and politics. Unlike earlier events, this one was not disturbed by demonstrations. DAtF President Dr. Wilfried Steuer welcomed Joachim H. Witt, Chief Executive Officer of the city of Aachen, who expressed words of welcome on behalf of his city at the opening of the plenary day of the conference. Energy policy and global competition were the optics of the address by Dr. Norbert Lammert, Parliamentary Undersecretary of State with the German Federal Ministry of Economics. He advocated grasping the changes offered by expanding global markets by reforming the structures of the energy supply sector. The rank of nuclear power in European research policy was explained by Fabricio Caccia Dominioni as representative of the European Commission. The electricity utilities were represented by Dr. Dietmar Kuhnt, Chief Executive Officer of RWE AG, who spoke about the security of energy investments. A thoughtful analysis of Germany as an industrial location was presented by Professor Dr. Herbert Henzler of McKinsey and Company Inc. The President of the European Nuclear Society (ENS), Ger R.

    Jacob, R; Stelzig, Y

    2013-01-01

    Restoration of impaired auditory function through cochlear implant is possible, with high reliably and great success. Nevertheless, there are regular disputes between patients and insurance companies due to high costs. In Germany, approx. 1.9 Mio. people are severely hearing impaired. It can be estimated that for adequate hearing rehabilitation about 30,000 cochlear implants/year are necessary. Currently, less than 10% of those affected are offered cochlear implant. A handicap is defined if there is deviation from normal hearing for more than 6 months. This sets a time frame for the supply with cochlear implant after sudden deafness. The professional code requires to advice all medical options to a person seeking help for hearing loss. This includes benefit-risk consideration. At this point, the economic aspect plays no role. The indication for medical treatment is only subject to the treating physician and should not be modified by non-physicians or organizations. It should be noted that a supply of hearing aids is qualitatively different to the help from a cochlear implant, which provides a restoration of lost function. In social law (SGB V and IX) doctors are requested to advise and recommend all measures which contribute to normal hearing (both sides). This indicates that doctors may be prosecuted for not offering help when medically possible, just because health insurance employees did not approve the cost balance. The current situation, with insufficient medical care for the hearing impaired, needs clarifying. To do this, patients, health insurance companies, the political institutions, legislation and professional societies need to accept their responsibilities.

    Founded 2011 the TUM Critical Zone Observatory run by the Technische Universität München and partners abroad is the first CZO within Germany. TUM CZO is both, a scientific as well as an education project. It is a watershed based observatory, but moving behind this focus. In fact, two mountainous areas are integrated: (1) The Ammer Catchment area as an alpine and pre alpine research area in the northern limestone Alps and forelands south of Munich; (2) the Otter Creek Catchment in the Bavarian Forest with a crystalline setting (Granite, Gneiss) as a mid mountainous area near Regensburg; and partly the mountainous Bavarian Forest National Park. The Ammer Catchment is a high energy system as well as a sensitive climate system with past glacial elements. The lithology shows mostly carbonates from Tertiary and Mesozoic times (e.g. Flysch). Source-to-sink processes are characteristic for the Ammer Catchment down to the last glacial Ammer Lake as the regional erosion and deposition base. The consideration of distal depositional environments, the integration of upstream and downstream landscape effects are characteristic for the Ammer Catchment as well. Long term datasets exist in many regards. The Otter Creek catchment area is developed in a granitic environment, rich in saprolites. As a mid mountainous catchment the energy system is facing lower stage. Hence, it is ideal comparing both of them. Both TUM CZO Catchments: The selected catchments capture the depositional environment. Both catchment areas include historical impacts and rapid land use change. Crosscutting themes across both sites are inbuilt. Questions of ability to capture such gradients along climosequence, chronosequence, anthroposequence are essential.

  13. Atomic energy laws in Germany

    International Nuclear Information System (INIS)

    Lukes, R.H.P.

    1980-01-01

    The regulations of German atomic energy laws are based in large on the fundamental law of the Federal Republic of Germany-the constitution. Atomgesetz of 1959, as amended on October 31, 1976, constitutes the core of atomic energy laws (Atomrecht), and is supplemented by orders (Verordnungen). The Federal Republic has the right to legislate Atomrecht, and the enforcement of such laws and orders is entrusted to each province. The peaceful uses of radioactive materials are stipulated by Atomgesetz and orders. Atomgesetz seeks two objects, first it is to enable the handling of radioactive substances for the acquisition of energy, medical treatment, food treatment and the harmless examination of things by radioactive materials, and secondly to ensure the protection from danger in the handling of such materials. The control of radioactive materials by the state including imports and exports, storage and possession, disposal and processing, etc., is established by the law to secure the protection from danger of atomic energy. The particular indemnification responsibility for the harm due to radiation is defined in Atomgesetz, and only the owners (Inhaber) of atomic energy facilities are liable for damage. The violation of the regulations on the transaction of radioactive materials is punished by fines up to 100,000 German marks of imprisonment of less than five years. Orders are established on roentgen ray, the protection from radiation, the treatment of foods by electron beam, gamma ray, roentgen ray or ultraviolet ray and the permission of medicines. The regulations of the EURATOM treaty have legality as Atomrecht. (Okada, K.)

    The responsibility for the disposal of radioactive waste is regulated in the Federal Republic of Germany in the Atomic Energy Act. Basically, it is the responsibility of the waste producers to carry out all necessary processing steps up to the delivery to a repository. The Federal Republic reserves the right to select, explore and operate the repository (§ 9a, para. 3 AtG). The costs of all necessary expenditures of this task are borne by the waste producers in accordance with § 21 AtG regulation. The waste quantity forecasts have shown that by the year 2080 a total volume of about 300,000 m3 of low- and intermediate-level (non-heat-generating) waste will be generated in research, industry, medicine and in the production of electricity in nuclear power plants. This waste is to be transported to the ‘Konrad repository’ which is under construction. The Federal Office for Radiation Protection (BfS), which is responsible for the construction and operation, intends to commission the repository at 2019. As a repository for heat-generating wastes, i. Approximately 10.000 tSM spent fuel (BE) 7,500 molds (HAW and MAW, corresponding to about 6000 tSM) returned Waste from reprocessing, the Gorleben salt dome has been explored since 1979. The works were resumed on 01.10.2010 after a 10-year break. Federal Environment Minister Röttgen has made it clear that the Federal Government has proposed a transparent procedure and a dialogue and participation procedure for open-ended exploration.

  15. Changing Sediment Dynamics of a Mature Backbarrier Salt Marsh in Response to Sea-Level Rise and Storm Events

    Directory of Open Access Journals (Sweden)

    Mark Schuerch

    2018-05-01

    Full Text Available Our study analyses the long-term development of a tidal backbarrier salt marsh in the northern German Wadden Sea. The focus lies on the development of the high-lying, inner, mature part of the salt marsh, which shows a striking history of changing sediment dynamics. The analysis of high-resolution old aerial photographs and sampled sediment cores suggests that the mature part of the marsh was shielded by a sand barrier from the open sea for decades. The supply with fine-grained sediments occurred from the marsh inlet through the tidal channels to the inner salt marsh. Radiometric dating (210Pb and 137Cs reveals that the sedimentation pattern changed fundamentally around the early-mid 1980s when the sedimentation rates increased sharply. By analyzing the photographic evidence, we found that the sand barrier was breached during storm events in the early 1980s. As a result, coarse-grained sediments were brought directly through this overwash from the sea to the mature part of the salt marsh and increased the sedimentation rates. We show that the overwash and the channels created by these storm events built a direct connection to the sea and reduced the distance to the sediment source which promoted salt marsh growth and a supply with coarse-grained sediments. Consequently, the original sediment input from the tidal channels is found to play a minor role in the years following the breach event. The presented study showcases the morphological development of a mature marsh, which contradicts the commonly accepted paradigm of decreasing sedimentation rates with increasing age of the marsh. We argue that similar trends are likely to be observed in other backbarrier marshes, developing in the shelter of unstabilized sand barriers. It further highlights the question of how resilient these salt marshes are toward sea level rise and how extreme storm events interfere in determining the resilience of a mature salt marsh.

    Synthetic polycyclic musk fragrances Galaxolide (HHCB) and Tonalide (AHTN) were measured simultaneously in air and seawater in the Arctic and the North Sea and in the rural air of northern Germany. Median concentrations of gas-phase HHCB and AHTN were 4 and 18 pg m(-3) in the Arctic, 28 and 18 pg m(-3) in the North Sea, and 71 and 21 pg m(-3) in northern Germany, respectively. Various ratios of HHCB/AHTN implied that HHCB is quickly removed by atmospheric degradation, while AHTN is relatively persistent in the atmosphere. Dissolved concentrations ranged from 12 to 2030 pg L(-1) for HHCB and from below the method detection limit (3 pg L(-1)) to 965 pg L(-1) for AHTN with median values of 59 and 23 pg L(-1), respectively. The medians of volatilization fluxes for HHCB and AHTN were 27.2 and 14.2 ng m(-2) day(-1) and the depositional fluxes were 5.9 and 3.3 ng m(-2) day(-1), respectively, indicating water-to-air volatilization is a significant process to eliminate HHCB and AHTN from the North Sea. In the Arctic, deposition fluxes dominated the air-sea gas exchange of HHCB and AHTN, suggesting atmospheric input controls the levels of HHCB and AHTN in the polar region.

    A numerical variable-density groundwater model is set up for the North Sea Island of Borkum to estimate climate change impacts on coastal aquifers and especially the situation of barrier islands in the Wadden Sea. The database includes information from boreholes, a seismic survey, a helicopter-borne electromagnetic survey (HEM), monitoring of the freshwater-saltwater boundary by vertical electrode chains in two boreholes, measurements of groundwater table, pumping and slug tests, as well as water samples. Based on a statistical analysis of borehole columns, seismic sections and HEM, a hydrogeological model is set up. The groundwater model is developed using the finite-element programme FEFLOW. The variable-density groundwater model is calibrated on the basis of hydraulic, hydrological and geophysical data, in particular spatial HEM and local monitoring data. Verification runs with the calibrated model show good agreement between measured and computed hydraulic heads. A good agreement is also obtained between measured and computed density or total dissolved solids data for both the entire freshwater lens on a large scale and in the area of the well fields on a small scale. For simulating future changes in this coastal groundwater system until the end of the current century we use the climate scenario A2, specified by the Intergovernmental Panel on Climate Change and in particular the data for the German North Sea coast. Simulation runs show proceeding salinization with time beneath the well fields of the two waterworks Waterdelle and Ostland. The modelling study shows that spreading of well fields is an appropriate protection measure against excessive salinization of the water supply until the end of the current century.

  18. Germany. A pioneer on earthen feet?

    International Nuclear Information System (INIS)

    Michaelowa, A.

    2003-01-01

    Germany is one of the two OECD countries having achieved substantial greenhouse gas reductions in the last decade. While a part was large reductions in industry after the economic crash in East Germany, a relevant share is due to the huge public infrastructure investments in East Germany. The real success of German climate policy in the past decade is the strong reduction of methane and nitrous oxide which has been almost unnoticed. German climate policy is a good example of how lobbying of interest groups leads to a complex maze of hundreds of measures whose effects are difficult to evaluate. Paradoxically, policies have focused on expensive measures and Germany clearly is a pioneer in the most expensive forms of renewable energy. Concerning cost-effective measures and market instruments, Germany is a laggard. Only slowly, policymakers start to notice this distortion and first, shaky steps towards a more cost-efficient policy are made. Several challenges such as nuclear phase-out and trends in household energy consumption will put pressure on government to embrace the Kyoto Mechanisms and to refocus domestic instruments well before the first commitment period

    2018-02-01

    We present a 1-km2 gridded German dataset of hourly surface climate variables covering the period 1995 to 2012. The dataset comprises 12 variables including temperature, dew point, cloud cover, wind speed and direction, global and direct shortwave radiation, down- and up-welling longwave radiation, sea level pressure, relative humidity and vapour pressure. This dataset was constructed statistically from station data, satellite observations and model data. It is outstanding in terms of spatial and temporal resolution and in the number of climate variables. For each variable, we employed the most suitable gridding method and combined the best of several information sources, including station records, satellite-derived data and data from a regional climate model. A module to estimate urban heat island intensity was integrated for air and dew point temperature. Owing to the low density of available synop stations, the gridded dataset does not capture all variations that may occur at a resolution of 1 km2. This applies to areas of complex terrain (all the variables), and in particular to wind speed and the radiation parameters. To achieve maximum precision, we used all observational information when it was available. This, however, leads to inhomogeneities in station network density and affects the long-term consistency of the dataset. A first climate analysis for Germany was conducted. The Rhine River Valley, for example, exhibited more than 100 summer days in 2003, whereas in 1996, the number was low everywhere in Germany. The dataset is useful for applications in various climate-related studies, hazard management and for solar or wind energy applications and it is available via doi: 10.5676/DWD_CDC/TRY_Basis_v001.

    In this short paper an overlook is given of the systems developed in Germany for filtered containment venting and their implementation in nuclear power plants. More information on the development can be found in the Proceedings of the DOE/NRC Aircleaning Conferences. In Germany, 28.8 % of the electric energy is produced by 19 nuclear power reactors. No new power reactor is expected to be built at least within the next ten years, but France and Germany cooperate in the development of a future European Power Reactor (ERP). This reactor type will be fitted with a core catcher and passive cooling in order to avoid serious consequences of a hypothetical core meltdown accident so that provisions for containment venting are not required. 3 refs., 6 figs., 1 tab

    High population density and intense industrialization in both parts of Germany resulted in high specific power demands. The domestic availability of hard coal and lignite made coal-fired power plants the backbone of power generation in all of Germany. The unification of Germany has brought together two power generation systems with similar basic needs and concepts. However, forty years existence within different economic systems has resulted in a quite different status in regard to installed generating capacity, availability of various fuels and environmental standards. To bridge the existing gap in a relatively short time is a huge challenge for the utilities, the power generation and distribution industry as well as for the federal and state authorities

    AREVA NP was created in 2001 by the merger of the French nuclear technology specialist Framatome with the nuclear sector of Siemens. The company is headquartered in Paris and has regional subsidiaries in Germany and the United States. The joint venture's strength lies in its all-round competence in nuclear power plants, from reactor development to power plant services and modernization of operating plants, design and production of fuel assemblies and turn-key construction of nuclear power reactors. Major core competences are located in Germany including the test facilities which are unique in the entire group as well as electrical engineering and instrumentation and control systems. AREVA NP is part of the globally acting AREVA group which pursues a unique integrated business model. The concept covers the entire nuclear fuel cycle from uranium mining to reprocessing used fuel assemblies. At present, AREVA has 48,000 employees worldwide, of which 5,700 are Germany-based. (orig.)

  3. Provisions for containment venting in Germany

    Energy Technology Data Exchange (ETDEWEB)

    Wilhelm, J.G.

    1997-08-01

    In this short paper an overlook is given of the systems developed in Germany for filtered containment venting and their implementation in nuclear power plants. More information on the development can be found in the Proceedings of the DOE/NRC Aircleaning Conferences. In Germany, 28.8 % of the electric energy is produced by 19 nuclear power reactors. No new power reactor is expected to be built at least within the next ten years, but France and Germany cooperate in the development of a future European Power Reactor (ERP). This reactor type will be fitted with a core catcher and passive cooling in order to avoid serious consequences of a hypothetical core meltdown accident so that provisions for containment venting are not required. 3 refs., 6 figs., 1 tab.

    A checklist of the German earthworm fauna (Oligochaeta: Lumbricidae) is presented, including published data, data from reports, diploma- and PhD- theses as well as unpublished data from museum collections, research institutions and private persons. Overall, 16,000 datasets were analyzed to produce the first German checklist of Lumbricidae. The checklist comprises 46 earthworm species from 15 genera and provides ecological information, zoogeographical distribution type and information on the species distribution in Germany. Only one species, Lumbricus badensis Michaelsen, 1907, is endemic to Germany, whereas 41% are peregrine. As there are 14 species occurring exclusively in the southern or eastern part of Germany, the species numbers in German regions increase from north to south.

    In order to answer the question how a greenhouse gas neutral Germany would look like an interdisciplinary process was started by the Federal Environmental Agency. It was clear from the beginning of this work that a sustainable regenerative energy supply could not be sufficient. Therefore all relevant emission sources were included into the studies: traffic, industry, waste and waste water, agriculture, land usage, land usage changes and forestry. The necessary transformation paths to reach the aim of a greenhouse gas neutral Germany in 2050, economic considerations and political instruments were not part of this study.

    2015-10-01

    In spite of several approved analgesics, the therapy of pain still constitutes a challenge due to the fact that the drugs do not exert sufficient efficacy or are associated with severe side effects. Therefore, the development of new and improved painkillers is still of great importance. A number of highly qualified scientists in Germany are investigating signal transduction pathways in pain, effectivity of new drugs and the so far incompletely investigated mechanisms of well-known analgesics in preclinical and clinical studies. The highlights of pharmacological pain research in Germany are summarized in this article.

    Frohberg, K.; Weingarten

    1997-01-01

    Agricultural activities always have impacts on the environment. Whereas soil erosion is a minor problem in Germany water pollution due to modern and intensive agriculture is of major concern. At first the paper discusses to what extent agriculture contributes to environmental pollution in Germany, in particular to the pollution of surface waters (as well as hydroelectric power constructions on the Danube) and groundwater by nutrients and pesticides. Agro-environmental policy in Germany is dominated by command-and-control-measures. Hence, in the second section, recent developments of the most important legal and institutional settings concerning water conservation policies are surveyed with special emphasis on the Federal Water Act and the Implementation of the Nitrate Directive into German legislation by the Fertilizer Ordinance. Thirdly, impacts of alternative water conservation policies are investigated using a regionalized agricultural sector model. Information obtained by this model analysis cover the development of N-balances, potential nitrate concentrations in the recharged groundwater, costs potentially effected by this and resulting agricultural incomes on the country level of the former Federal Republic Germany. The last section focuses on programs promoting environmentally sound farming practices, which gained increasing importance in the Common Agricultural Policy of the European Union in the last years. It is argued that this development will also continue in the future. (author)

  20. Recollections of a jewish mathematician in Germany

    CERN Document Server

    2016-01-01

    Abraham A. Fraenkel was a world-renowned mathematician in pre–Second World War Germany, whose work on set theory was fundamental to the development of modern mathematics. A friend of Albert Einstein, he knew many of the era’s acclaimed mathematicians personally. He moved to Israel (then Palestine under the British Mandate) in the early 1930s. In his autobiography Fraenkel describes his early years growing up as an Orthodox Jew in Germany and his development as a mathematician at the beginning of the twentieth century. This memoir, originally written in German in the 1960s, has now been translated into English, with an additional chapter covering the period from 1933 until his death in 1965 written by the editor, Jiska Cohen-Mansfield. Fraenkel describes the world of mathematics in Germany in the first half of the twentieth century, its origins and development, the systems influencing it, and its demise. He also paints a unique picture of the complex struggles within the world of Orthodox Jewry in Germany....

  12. Is Germany a model for managers?

    Science.gov (United States)

    Wever, K S; Allen, C S

    1992-01-01

    Most American managers have a hard time making sense of Germany. The country has a fraction of the resources and less than one-third the population of the United States. Labor costs are substantially higher, paid vacations are at least three times as long, and strong unions are deeply involved at all levels of business, from the local plant to the corporate boardroom. Yet German companies manage to produce internationally competitive products in key manufacturing sectors, making Germany the greatest competitive threat to the United States after Japan. The seemingly paradoxical nature of the German economy typically evokes one of two diametrically opposed responses. The first is to celebrate the German economy as a "model" worth emulating--indeed, as the answer to declining U.S. competitiveness. The alternative, more skeptical response is to question Germany's staying power in a new, more competitive global economy. According to Kirsten Wever and Christopher Allen, the problem with both points of view is that they miss the forest for the trees. Observers are so preoccupied with praising--or blaming--individual components of the German economy that they fail to see the dynamic logic that ties these components together into a coherent system. In their review of recent research on the German business system, Wever and Allen argue that managers can learn an important lesson from Germany. In the global economy, competition isn't just between companies but between entire socioeconomic systems. Germany's ability to design a cohesive economic and social system that adapts continuously to changing requirements goes a long way toward explaining that country's competitive success.

  13. [Performance of in vitro fertilization in Germany].

    Science.gov (United States)

    van der Ven, Hans; Montag, Markus; van der Ven, Katrin

    2002-07-01

    In Germany the application of assisted reproductive techniques (ART) is regulated by federal legislation. Compared with the international situation the "German Embryo Protection Law" is very "restrictive" and various methods of ART are prohibited, e.g. oocyte/embryo donation, embryo cryopreservation and Preimplantation Genetic Diagnosis (PGD). Furthermore, in Germany only 1 to 3 fertilized oocytes may be cultured to embryo. All these embryos then have to be transferred into the uterus of a particular patient. Additional fertilized oocytes can only be cryopreserved in a pronuclear state. The success rate of ART has increased significantly over the past few years owing to the introduction of blastocyst cultures and the selection of 1 to 2 good quality blastocysts for embryo transfer. Furthermore, the transfer of only 1 to 2 blastocysts effectively reduces the risk of high rank multiple pregnancies. In Germany, however, the selection of only a few good quality blastocysts for transfer is prohibited by law. New laboratory techniques, e.g. pronuclear scoring and polar body biopsy screening for aneuploidy are in accordance with German law. The application of these methods provides a selection of "good quality oocytes" and seems to increase the overall success rate. Further studies are required, however. The success rate, quality and cost effectiveness of ART in Germany appears compromised when compared with many other countries. What is more, in contrast to the international situation research and development in ART in Germany has been decreasing constantly over the past few years, due to the inappropriate regulations of the German health care system and the insufficient support given to university-based centers.

  14. The outlook for natural gas in Germany

    International Nuclear Information System (INIS)

    Bergmann, B.

    1993-01-01

    In a generally stagnant energy market, gas will be the energy with the highest growth rate in Germany, especially because of its steadily rising shares in the residential and commercial sector. In western Germany there is to be accepted that the demand forecasts, which were raised from one conference to the next, have passed their zenith. Great uncertainty exists as regards the future use of gas for power generation. In the absence of any significant expansion of this market sector, which is considered rather improbable in western Germany, it can be stated that anticipated gas demand up to the year 2005 is already covered by existing import contracts and scheduled domestic production. The picture is completely different in eastern Germany, where a doubling of consumption is quite feasible. To achieve the requisite diversification of supplies, substantial additional imports from western sources will have to be contracted. Russia can and should remain eastern Germany's main supplier in the long run, but Russian deliveries must be placed on a reliable, long-term contractual basis. As far as new gas projects are concerned, deliveries from Norway, to a limited extent from the United Kingdom and above all as part of the new Russian export initiative are under discussion. Generally speaking, transit will be an increasingly significant issue, especially for additional supplies from Russia. The efficiency and reliability of gas marketing companies will become far more important in an environment characterised by growing uncertainties. The reliable customer offering a dependable market outlet will be increasingly sought. With energy prices likely to increase only slightly, the management of uncertainties and the safeguarding of economic driving forces will be the main challenge facing our supply projects. 15 figs

    Helmert, U; Mielck, A; Shea, S

    1997-01-01

    To investigate the relation between poverty and several variables describing health and nutrition behavior in East Germany and West Germany. Data are from the third National Health Survey in West Germany and the first Health Survey for the new federal states of Germany (1991/92). Both health surveys included a self-administered questionnaire ascertaining sociodemographic variables, smoking history, nutritional behavior (using a food-frequency list), physical activity, and a medical examination comprising measurements of height, weight, blood pressure, and blood sampling for serum cholesterol determination. Participants included 4958 subjects in the West Survey and 2186 subjects in the East Survey aged 25-69 years, with a respective net response rate of 69.0% and 70.2%. Poverty was defined as a household equivalence income of 62.5% or less of the median income of the general population. The lowest income group (poverty or near poverty) comprised 11.6% of East German versus 15.9% of West German males and 14.8% of East German versus 19.3% of West German females. For most but not all health and nutrition parameters, less favorable results were obtained for subjects with an equivalence income below or near poverty. The most striking poverty-related differences regarding cardiovascular disease risk factors were found for lack of regular exercise for both genders and obesity in females. No poverty-related differences were found for the prevalence of hypercholesterolemia, despite a much higher prevalence of obesity in persons with an income below the poverty line. Current nutritional behavior and changes in nutritional behavior during the last three years was strongly related to income status, with a more unhealthy status for low-income population groups in both East and West Germany. In Germany, poverty has strong effects on individual health status and nutritional behavior. Because of rising unemployment rates and reductions in social security payments for low

    and topobathymetric surveys using high-resolution red and green Light Detection And Ranging (LiDAR), respectively. Detailed digital elevation models with a grid cell size of 1 m x 1 m were generated and analysed geomorphometrically. The analyses reveal a main ebb-directed net sand transport in the main channel......; however, due to the geometry of the main channel, displaying a confluent meander bend, confined areas in the main channel are characterised by an opposite-directed net sand transport. In the inter-tidal areas the main net sand transport is flood-directed. However, also here the analyses reveal...... that during storm events with winds from SW, sand is transported from the inlet channel to the intertidal flat. Hence, in addition to the typical main sand transport directions with net export in the inlet channel and net import over the adjacent inter-tidal flats, these investigations suggest an exchange...

    Full Text Available Germany's socio-economic model, the "social market economy", was established in West Germany after World War II and extended to the unified Germany in 1990. During a prolonged recession after the adoption of the Euro in 1998, major reforms (Agenda 2010 were introduced which many consider as the key of Germany's recent success. The reforms had mixed results: employment increased but has consisted to a large extent of precarious low-wage jobs. Growth depended on export surpluses based on an internal real devaluation (low unit labour costs which make Germany vulnerable to global recessions as in 2009. Overall inequality increased substantially.

    Set off by the oil crisis in the Seventies and nurtured by the critical stance of the public towards nuclear energy and its growing awareness of the climate problem, studies on possible applications of renewables in Germany have played an increasingly important role over the years. A large number of publications have been turned out on this issue. It therefore appears worthwhile to collect the various results given in the literature and compile them for easy comparison. The authors of the present article give a short synopsis of a study to this end that was completed in the autumn of last year. The chief aim of the compilation was to enable the reader to gain a quick overview of the known results and to facilitate his orientation, thus making the problems surrounding the application of renewables in Germany more transparent.

  3. Second births in western Germany and France

    Full Text Available We compare second birth risks in France and western Germany using data from the Family and Fertility Survey. Second birth risks are higher for highly educated women than for women with lower education in both countries. In western Germany, the positive effect weakens after controlling for the education level of the partner. The positive effect of French women's education remains unchanged, even after controlling for the partners' characteristics. We interpret this finding in the sense that work and family life are more compatible in France, where highly educated women can turn their education more often into work opportunities and income. West German women often have to make a decision between an employment career and motherhood as two exclusive life options. In such a situation, it is primarily the partners' earning potential that influences fertility.

  4. The future of nuclear power in Germany

    Holzer, J.

    1993-01-01

    The future of nuclear power in Germany is not only a matter of technology, economy and ecology but, above all, a matter of political leadership, the quality of interaction of all groups of society, the need to take ideology out of politico-economico-technical matters, and of firmly standing up for a style of democracy in which majorities, not minorities, decide. The power economy is agreed that nuclear power is indispensable in a powerful electricity supply scheme. These should be the criteria to be met by an energy consensus: No nuclear plants should be sacrificed by being shut down before the end of their technical and economic service life; spent fuel and waste management in Germany should be secured with sufficient interim storage and repository storage capacities.

    First the discussion of Kohut's new ideas in the United States is sketched as a background. The response to these ideas was divided: on the one hand they were hailed as important innovations of psychoanalytic theory, and a circle of colleagues formed around their author; on the other hand they were violently rejected, and old friends distanced themselves from him. In Germany Kuhut's ideas were initially well received. His visits, lectures and supervisions resulted in a lively exchange and a number of friendships. When the differences between Kohutian and classical theory became evident this led increasingly to disillusionment and retreat. De-emphasizing drive and ego psychology had considerable consequences for psychoanalytic technique as well as for the analyst's Menschenbild, his relationship to the patient and his critical self-reflection. In Germany, too, a circle of colleagues emerged, following and elaborating the ideas of Kohut.

    The train crash of Bad Aibling/Germany in February 2016 and the terrorist attacks of the recent years in Europe have demonstrated the urgent need to be prepared for such disastrous events. Disaster preparedness and disaster control are very important governmental duties, as are civil protection and civil defense. In Germany the responsibility for those tasks are divided between the 16 "Länder" and the Federation. While the Federation takes care of the civil protection and disaster assistance, the Länder are responsible for disaster control. The presented article focuses on these issues and gives valuable insights into the German system of disaster control and civil protection with a focus on health protection.

    Glebe, G

    1997-01-01

    "The accelerating economic globalization has created a growing demand for highly skilled labourers. As a result, there has been an increase in highly skilled and high-status migrants to Germany, especially to the urban agglomerations with global city functions. This migration process is carried mostly by the internal labour and job movement of multinational companies. In the urban centres these groups of migrants follow specific patterns of spatial organization and segregation with regard to their place of residence. But they also have other distinctive difference to the migrants with a lower social status, such as higher social acceptance in their host country, the transitory character of their stay in Germany, and their intentions to return to their home countries."

    2000-01-01

    This paper describes the state of essential demonstration projects of heat and cold storage in aquifers in Germany. Into the energy supply system of the buildings of the German Parliament in Berlin, there are integrated both a deep brine-bearing aquifer for the seasonal storage of waste heat from power and heat cogeneration and a shallow-freshwater bearing aquifer for cold storage. In Neubrandenburg, a geothermal heating plant which uses a 1.200 m deep aquifer is being retrofitted into an aquifer heat storage system which can be charged with the waste heat from a gas and steam cogeneration plant. The first centralised solar heating plant including an aquifer thermal energy store in Germany was constructed in Rostock. Solar collectors with a total area of 1000m 2 serve for the heating of a complex of buildings with 108 flats. A shallow freshwater-bearing aquifer is used for thermal energy storage. (Authors)

  9. Year 2 of Germany's Energy Transition

    Cruciani, Michel

    2013-01-01

    After a decade characterised by the take-off of renewable energies, Germany decided in 2010 to make them the top priority. At the same time, it decided to make exemplary efforts in terms of energy efficiency and the reduction of greenhouse gases. The audacious nature of this policy was strengthened by the 'turn' taken in 2011 to give up nuclear energy in the wake of the Fukushima accident. Given the initial results for 2012, Germany seems to be on target for reaching its national objective, of 18% renewable energy within total consumption by 2020. Germany is also well placed to reduce its planned cut in electricity consumption of 10%. The country will also meet its commitments, both international and European, concerning greenhouse gas emissions. In contrast, recent trends suggest it will be increasingly difficult for Germany to meet its own, domestic goal of cutting emissions by 40%, by 2020. Furthermore, it is hard to see how Germany will be able to bring down total energy consumption by 20% by 2020 (from 2008 levels), or increase the share of renewables in electricity production above 35%. Success with this latter objective is largely dependent on reinforcing networks, both for transmission over long distances and for local distribution. It is not sure that the delays accumulated in both areas will be made up for by 2020, despite the rapid legislative adjustments that have already been made. By favouring intermittent energy sources - wind and solar power - Germany also faces problems of managing frequent production fluctuations. The long term solution to this lies in storing electricity. However, despite the considerable efforts in research and development, the technologies necessary for this will doubtless not be available on a large scale before the end of the present decade. These efforts could nevertheless provide German industry with interesting advantages in sectors of high potential, such as electric vehicles. Measures to promote renewable energies are

    1999-01-01

    This paper analyses the role of bank lending in the monetary transmission process in Germany. We follow a sectoral approach by distinguishing corporate lending and household lending. We find that banks respond to a monetary contraction by adjusting their securities holdings, rather than reducing their loans portfolio. Most lending categories even show an increase following a monetary tightening. The main implication of our results is that a bank lending channel is not an important transmissio...

    2008-03-01

    Full Text Available A rather significant proportion of the Societas Europaeas (the European Company, or SE formed to date have had German roots. German corporate law has been enriched by an interesting alternative which meanwhile seems to have gained momentum. This contribution focuses on SEs incorporated by German entrepreneurs and provides an interesting account concerning the use of SEs in Germany in practice, such as Allianz, Fresenius, BASF and Porsche. Has the SE been used to circumvent rigid company law provisions or is it a more flexible and effective tool, perhaps, for company mobility? The practical motives behind setting up this company form are also reflected upon. These include: the facilitation of cross-border mergers; transfer of the registered office; the ‘European’ image; a more flexible form of co-determination in large companies (reduction of the number of supervisory board members; avoidance and freezing of co-determination for medium-sized enterprises; the appeal of the one-tier system and its endangerment by German co-determination; and flat and uniform structures for company groups. The author also briefly discusses some of the problems arising from the formation of SEs in Germany. He ultimately concludes that practice has shown that it is possible to work with the legal regime of the SE in Germany, which adds a new company form to those available in that Member State.

    In November 2012, 23 cases of ciguatera with typical combinations of gastrointestinal and neurological symptoms occurred in Germany after consumption of imported tropical fish (Lutjanus spp.). A questionnaire was used to gather information on the disease course and fish consumption. All patients suffered from pathognomonic cold allodynia. Aside from two severe courses of illness, all other cases showed symptoms of moderate intensity. During a three-year follow-up, seven patients reported prolonged paresthesia for more than one year. Two of them reported further neuropathies over almost three years. This is the first time that long-term persistence of symptoms has been documented in detail. Outbreak cases were allocated to eight clusters in seven German cities. A further cluster was prevented by the successful recall of ciguatoxic fish. Three clusters were confirmed by the detection of ciguatoxin in samples of suspicious and recalled fish. An extrapolation on the basis of ciguatoxic samples revealed twenty prevented cases of ciguatera. Further officially unknown cases should be assumed. During the outbreak investigations, inadvertently falsely labelled fish species and fishing capture areas on import and retail level documents were observed. The ascertainment of cases and the outbreak investigations proved to be difficult due to inconsistent case reports to poisons centers, local health and veterinary authorities. In Germany, many physicians are unaware of the disease pattern of ciguatera and the risks caused by tropical fish. The occurrence of further outbreaks during the following years emphasizes the increasing significance of ciguatera in Germany.

    The final storage of radioactive waste and spent fuel in Germany - who, in Germany, has any interest in this subject, especially now that the new Atomic Energy Act has been adopted, and who is going to read this article? The author, Professor Klaus Kuehn, examines this question, analyzing in his contribution the current situation and the points of view of those who may be interested in this topic. In Prof. Kuehn's opinion, the addresses in particular are these: - the federal government, - the opposition in the federal parliament, - the federal states, - the Federal Ministry for the Environment, - the Federal Ministry for Research, - the Federal Ministry of Economics, - the Federal Office for Radiation Protection, - the operators of nuclear power plants, - the Working Group Elaborating Procedures for Selecting Repository Sites (AkEnd). Klaus Kuehn concludes that there is little interest at the present time in the subject of Final Storage in Germany, for reasons explained in detail which result both from the political constellation and from existing constraints.

    Full Text Available The process of socio-economic transformation of East German lands after the German reunification in 1990 is analyzed, the term "transformation" in frames of planned and market economies is defined. The author studies the historical determinants of the transformation process in Germany. German economic and industrial history in context of the driving forces and their social values, as well as the properties of the planning and economic systems that underlie the transformation of East German mentality, are considered. Further analysis is connected with economic, social and political components of the East German transformation process, "the dominance of the West", the collapse of the Council for Mutual Economic Assistance, privatization etc. Finally, the outcome of already traversed path of transformation of East Germany is considered. It is concluded, that the transformation process is not only historically conditioned situations of both the merging parties in the case of Germany, but also the positive or negative perception of its results and the motivation for its further implementation.

  3. Deep Geothermal Energy Production in Germany

    Full Text Available Germany uses its low enthalpy hydrothermal resources predominantly for balneological applications, space and district heating, but also for power production. The German Federal government supports the development of geothermal energy in terms of project funding, market incentives and credit offers, as well as a feed-in tariff for geothermal electricity. Although new projects for district heating take on average six years, geothermal energy utilisation is growing rapidly, especially in southern Germany. From 2003 to 2013, the annual production of geothermal district heating stations increased from 60 GWh to 530 GWh. In the same time, the annual power production increased from 0 GWh to 36 GWh. Currently, almost 200 geothermal facilities are in operation or under construction in Germany. A feasibility study including detailed geological site assessment is still essential when planning a new geothermal facility. As part of this assessment, a lot of geological data, hydraulic data, and subsurface temperatures can be retrieved from the geothermal information system GeotIS, which can be accessed online [1].

    1999-01-01

    Germany's total national (i.e., combined public and private sector) funding for R and D stood at$42 billion in 1997. The private sector accounted for nearly 62% ($24 billion) of the total, while the public sector accounted for approximately 38%. Since the late 1970s, when the public and private sectors each funded roughly half of Germany's R and D, the private sector has steadily assumed a larger and larger role as the dominant supporter of R and D activity, while overall government funding has remained essentially flat for much of the past two decades. In addition to declining relative to private R and D expenditures, public R and D expenditures in Germany declined by 4% in real terms between 1991 and 1997, to approximately$15 billion. The reduction in R and D investments in the public sector can be attributed in large part to the financial challenges associated with German reunification and related shifts in social priorities including efforts to address high unemployment and to rebuild basic infrastructure in the eastern states. R and D expenditures have also declined as a percentage of the total public budget, from a peak of 3.4% in 1985 to 2.7% in 1996. Energy R and D has been the hardest hit of all major socioeconomic areas of R and D expenditure funded by the German government. Between 1981 and 1997, public energy R and D fell from approximately$1.6 billion to$400 million--a 75% real decline. The$850 million reduction in Germany's fission R and D budget (which constituted two-thirds of government R and D investment in 1985) explains some 90% of the funding decline. Negative public perceptions regarding the safety and environmental impacts of nuclear energy have reduced nuclear power's viability as a long-term energy option for Germany. Discussions of a complete nuclear phaseout are now under way. At the same time, the German government has slashed its investments in fossil energy R and D by more than 90%.

  7. Nuclear third party liability in Germany

    International Nuclear Information System (INIS)

    Raetzke, Christian

    2016-01-01

    The German system of nuclear third party liability has always been, and arguably still is, the object of considerable interest in the international nuclear law community. This may seem surprising since Germany adheres to the Paris Convention and is therefore a party to a community of 15 states all following the same principles enshrined in this Convention. In fact, when implementing the PC, Germany chose the approach ensuring the most literal adherence to the PC's principles: it adopted the PC in its entirety, thus directly transposing the PC text into binding German law, instead of enacting a national law derived from, but not literally translating, the PC. At the same time, perhaps no other nation has made use of the options, choices and margins offered or abandoned by the PC to the national legislators, or kept in store by way of a reservation at signature of the Convention, in such an extended manner, testing - and as has even been contended in the past: stressing - the boundaries of the PC system. Unlimited liability introduced in 1985, the highest financial security of any PC state (EUR 2.5 billion), unlimited territorial scope combined with the principle of reciprocity and liability of German operators even in the force majeure cases of Article 9 of the PC are probably the most interesting decisions made by Germany in this context, established in the Atomic Energy Act (Atomgesetz). These choices betray a certain tendency of the German government to give the greatest possible benefit to victims, and in parallel to achieve a 'normalisation' of the nuclear liability regime, without stifling the industry. Within the compromise underlying the international nuclear liability regime - enabling the nuclear industry to create and sustain an energy sector highly relevant for national electricity production on the one hand and protecting potential victims on the other - Germany has more and more shifted the balance, as far as practically possible, to the

    2014-05-01

    The Baltic Sea region, defined as its river catchment basin, spans different climate and population zones, from a temperate, highly populated, industrialized south with intensive agriculture to a boreal, rural north. It encompasses most of the Scandinavian Peninsula in the west; most of Finland and parts of Russia, Belarus, and the Baltic states in the east; and Poland and small parts of Germany and Denmark in the south. The region represents an old cultural landscape, and the Baltic Sea itself is among the most studied sea areas of the world. Baltic Earth is the new Earth system research network for the Baltic Sea region. It is the successor to BALTEX, which was terminated in June 2013 after 20 years and two successful phases. Baltic Earth stands for the vision to achieve an improved Earth system understanding of the Baltic Sea region. This means that the research disciplines of BALTEX continue to be relevant, i.e. atmospheric and climate sciences, hydrology, oceanography and biogeochemistry, but a more holistic view of the Earth system encompassing processes in the atmosphere, on land and in the sea as well as in the anthroposphere shall gain in importance in Baltic Earth. Specific grand research challenges have been formulated, representing interdisciplinary research questions to be tackled in the coming years. A major means will be scientific assessments of particular research topics by expert groups, similar to the BACC approach, which shall help to identify knowledge gaps and develop research strategies. Preliminary grand challenges and topics for which Working Groups have been installed include: • Salinity dynamics in the Baltic Sea • Land-Sea biogeochemical feedbacks in the Baltic Sea region • Natural hazards and extreme events in the Baltic Sea region • Understanding sea level dynamics in the Baltic Sea • Understanding regional variability of water and energy exchange • Utility of Regional Climate Models • Assessment of Scenario Simulations

    A March 1990 international sea-going workshop in Bremerhaven, Germany provided the opportunity to conduct detailed sediment toxicity testing in concert with studies of fish histopathology, bioaccumulation, benthic community structure, and sediment chemical contamination in the North Sea. Two gradients of sediment chemical contamination were tested, one from an abandoned oil platform and the other from the mouth of the Elbe River northward to the Dogger Bank. Using a preponderance of evidence approach, it was determined that sediments nearest the Elbe are moderately polluted (pollution is defined as contamination, toxicity, and community alteration) and that sediments offshore and at the Dogger Bank are unpolluted. Sediments nearest the oil platform showed evidence for a low level of pollution, but there was no evidence of pollution 125 m from the platform. The results suggest the testable hypothesis that North Sea sediments away from point sources of pollution such as coastal areas and drilling platforms are presently not polluted. 46 refs., 2 figs., 6 tabs

    Remains of theropod dinosaurs are very rare in Northern Germany because the area was repeatedly submerged by a shallow epicontinental sea during the Mesozoic. Here, 80 Late Jurassic theropod teeth are described of which the majority were collected over decades from marine carbonates in nowadays abandoned and backfilled quarries of the 19th century. Eighteen different morphotypes (A-R) could be distinguished and 3D models based on micro-CT scans of the best examples of all morphotypes are included as supplements. The teeth were identified with the assistance of discriminant function analysis and cladistic analysis based on updated datamatrices. The results show that a large variety of theropod groups were present in the Late Jurassic of northern Germany. Identified specimens comprise basal Tyrannosauroidea, as well as Allosauroidea, Megalosauroidea cf. Marshosaurus, Megalosauridae cf. Torvosaurus and probably Ceratosauria. The formerly reported presence of Dromaeosauridae in the Late Jurassic of northern Germany could not be confirmed. Some teeth of this study resemble specimens described as pertaining to Carcharodontosauria (morphotype A) and Abelisauridae (morphotype K). This interpretation is however, not supported by discriminant function analysis and cladistic analysis. Two smaller morphotypes (N and Q) differ only in some probably size-related characteristics from larger morphotypes (B and C) and could well represent juveniles of adult specimens. The similarity of the northern German theropods with groups from contemporaneous localities suggests faunal exchange via land-connections in the Late Jurassic between Germany, Portugal and North America.

  17. The energy supply situation in Germany

    Lederer, P.

    2007-01-01

    The focus is on 4 energy supply issues of decisive relevance to energy supply in Germany, but also in other countries in Europe and worldwide: (1) How will the global energy situation develop? (2) What is the organization, and the development, of the market in which we are doing business? (3) What are the challenges facing the power industry in view of a threatening climate change? (4) Against this backdrop, how do we design the energy mix of the future? Analysis of these 4 points shows that, for a foreseeable time, all types of energy generation are necessary if Germany and Europe are to be supplied energy efficiently, securely, and in a way not polluting the environment. Hence, these concrete conclusions can be drawn: (1) We need more renewable energies in Germany, in Europe, and worldwide. (2) We need the development of 700 C coalfired power plant technology in order to first advance the development of CCS (carbon capture and storage) technology and thus minimize CO 2 emissions from fossil-fired power plants. (3) We need increases in energy efficiency which help us satisfy the steadily growing need for energy with dwindling fossil resources. (4) We need nuclear power because of its ability to produce baseload electricity free from CO 2 . For nuclear power, it is now important that politics and the power industry jointly find ways and means to reassess, in an unbiased way, the plant operating lives laid down in the current Atomic Energy Act. This is required, inter alia, because of the challenges in climate policy and because of global economic boundary conditions. (orig.)

  18. An ecological tax reform in Germany

    Bakker, L.; Bleijenberg, A.N.

    1992-01-01

    This study, being a part of the large research program 'External Effects of Energy Procurement' and coordinated by PROGNOS, concerns the distributional and macro-economic effects of the internalization of the external effects of the energy supply by means of an ecological tax reform. The PROGNOS study is focused on the costs and effects of energy production, procurement and consumption (in Germany), that are not taken care of by the market. Here a rough estimate is given of the macro-economic consequence and the distributional effects for the industrial sector and households in (West) Germany of an energy tax of which the revenues are 'reinjected' into the economy, mainly by lowering the financial burden on labour. First a description is given of the starting points of the study and the form of the energy tax. Subsequently attention is paid to the macro-economic effects, the sectoral effects, and the effects on the distribution of incomes for households. The model calculations for Western Germany and the Netherlands confirm the expectation that an ecological tax reform leads to the combined realization of employment and environmental objectives. Shifts in the sectoral structure may occur. Energy intensive branches of industry will have to give up a part of their market share in favour of labour-intensive sectors. The results also illustrate that there are several possibilities to prevent a change in the collective burden of regular expenses as a result of a tax or levy on energy, and that the effects of a fuel tax on the income distribution can be corrected. 5 figs., 19 tabs., 5 apps., 15 refs

  19. A Less Ambitious Energy Transition for Germany

    2017-08-01

    In the wake of the 2011 Fukushima nuclear disaster, the German authorities launched the country's energy transition, or Energiewende. With near unanimous support of Germany's citizens, it was seen as a society-wide project. The enthusiasm the Energiewende generated soon spread beyond the Rhine. Indeed, for many French people it became the model to follow. Replacing nuclear energy and fossil fuels with renewable energy sources that were local when possible, developing electric mobility and making progress towards a zero carbon economy were all virtuous goals. What's more, it seemed they could be attained over a relatively short period of time and at reasonable cost. Today, the Energiewende's future looks less bright. While Germany produces a third of its electricity from renewable energy, this comes at a high price. The cost of electricity for small consumers more than doubled between 2000 and 2013. At the same time, the country continues to rely on coal to produce a large share of its electricity and still has one of the highest levels of CO_2 per person in Europe. But Germany's population is divided about closing its coal-fired and lignite power plants, not to mention doing so would jeopardize its energy supply. Add to this the fact the massive development of intermittent renewable energy sources has made the German power grid unstable and has necessitated the construction of thousands of kilometers of high voltage lines amidst strong local opposition. Lastly, electrifying the transport sector could serve to compound the series of scandals that have hit the automotive industry. Against this backdrop, the coalition government formed following the September 2017 federal elections could very well lower the bar for the Energiewende. (author)

  20. The effectiveness of stuttering treatments in Germany.

    Persons who stutter (PWS) should be referred to the most effective treatments available, locally or regionally. A prospective comparison of the effects of the most common stuttering treatments in Germany is not available. Therefore, a retrospective evaluation by clients of stuttering treatments was carried out. The five most common German stuttering treatments (231 single treatment cases) were rated as to their perceived effectiveness, using a structured questionnaire, by 88 PWS recruited through various sources. The participants had received between 1 and 7 treatments for stuttering. Two stuttering treatments (stuttering modification, fluency shaping) showed favorable and three treatments (breathing therapy, hypnosis, unspecified logopedic treatment) showed unsatisfactory effectiveness ratings. The effectiveness ratings of stuttering modification and fluency shaping did not differ significantly. The three other treatments were equally ineffective. The differences between the effective and ineffective treatments were of large effect sizes. The typical therapy biography begins in childhood with an unspecified logopedic treatment administered extensively in single and individual sessions. Available comparisons showed intensive or interval treatments to be superior to extensive treatments, and group treatments to be superior to single client treatments. The stuttering treatment most often prescribed in Germany, namely a weekly session of individual treatment by a speech-language pathologist, usually with an assorted package of mostly unknown components, is of limited effectiveness. Better effectiveness can be expected from fluency shaping or stuttering modification approaches, preferably with an intensive time schedule and with group sessions. Readers will be able to: (a) discuss the five most prevalent stuttering treatments in Germany; (b) summarize the effectiveness of these treatments; and (c) describe structural treatment components that seem to be preferable

    The title project was carried out on behalf of and for account of the 'Umweltbundesamt' (UBA) Germany in co-operation with TNO-MEP and SC-DLO. The main products arising from this project are, for Germany, estimates of dry deposition with a high spatial resolution, which, in combination with wet deposition data, will be used for the calculation of critical load exceedances. The basic model used in this study was EDACS. This model calculates dry deposition fluxes on the basis of meteorological data and atmospheric concentrations of relevant species. As such, the project reported here further elaborates the work carried out in a previous project in 1996, with the following additions and/or improvements worked out: (a) The distribution of NH3 concentrations in Germany has now been calculated on a 5x5 km grid using the EUTREND model, while in the previous study these data were taken from the standard EMEP model; (b) Possible concepts for introducing cloud deposition into the inferential approach have been investigated, with results for a small study area in southern Germany shown; (c) Canopy exchange estimates for forest sites in Germany were related to parameters, also measured at these sites to gain better insight into the parameters controlling canopy uptake and leaching. SOx dry deposition fluxes were highest in central-east Germany, NOy fluxes in central-west Germany and NHx fluxes in north-west Germany. The highest dry deposition of potential acid (up to 15,000 eq. ha -1 y -1 in 1987) was calculated for 'Bundesland' Sachsen and the highest dry deposition load of nitrogen was calculated for Bremen (up to 2100 eq ha -1 y -1 in 1989). Dry deposition of SOx, NOy, NHx and potential acid in the 1993-1995 period decreased by 36%, 13%, 21% and 31%, respectively, compared to the 1987-1989 period The decrease in potential acid was highest in Sachsen (43%) and lowest in Baden-Wittemberg (12%). Dry deposition of non-sea salt Ca 2+ , K + , Mg 2+ and base cations decreased

  2. 2005 primary energy consumption in Germany

    2006-01-01

    According to preliminar calculations by the Arbeitsgemeinschaft Energiebilanzen (Working Party on Energy Balances, AGEB), the consumption of an aggregate 486 million TCE of primary energy resources in Germany last year was 1.3% below the level of the year before. Energy consumption was influenced by both the high level of prices and the development of the economy. Hardly any influence was attributable to the level of temperatures, which was largely unchanged compared to the figure of the year before. Oil consumption in 2005 in Germany dropped by nearly 2% to 174.8 million TCE. On the whole, oil with its 36% share in the energy balance remained by far the most important energy resource in Germany. Natural gas consumption of 110.4 million TCE was at the level of the year before. Its share in the primary energy balance rose slightly to 22.7%. Hard coal, because of lower use in power plants and the decline in iron making, showed a 4.6% drop in consumption to 62.8 million TCE. In this way, hard coal contributed 13% to total energy consumption. Lignite consumption dropped by 3.2% to 54.4 million TCE as a result of lower deliveries to power plants. Its 11.2% share in the total consumption of primary energy continued to make lignite the most important domestic energy resource. More than 90% of the lignite produced is used for electricity generation. The contribution to primary energy consumption of nuclear power dropped by more than 2% to 60.7 million TCE. Hydroelectric plants and wind power plants increased their contribution by 3.6%. The contribution to primary energy consumption made by all renewable energy resources rose to 4.6%. AGEB evaluates statistics of all areas of the power economy on the basis of standard criteria in order to combine these data in a comprehensive picture. Since 1994, the energy balances for Germany have been compiled by DIW on behalf of AGEB. (orig.)

    The peculiarities and the differences in the development of nuclear energy in the two neighboring countries are described. The development in France could be promoted more easily which was also due to the government structure. Uncomplicated licensing procedures and other factors permitted a less difficult realisation of the nuclear energy programme. Serious economic consequences in our country are pointed out. In this summary, the most important results and statements of a memorandum worked out by the KWU with the headline 'Germany/France - the electricity supply in comparison' are listed. (UA) [de

    1999-01-01

    Although Germany's scrap export exceeds the import, the imports of scrap amount to more than one million Mg per year. Radioactivity has been found mainly in imported scrap in Germany. This radioactivity can consist of surface contamination in scrap e.g. from the oil and gas industry, nuclear and other technical applications or of radiation sources, e.g. from medical or technical irradiation devices where the source has not been removed prior to scrapping. Fortunately really large sources have been involved in only very few occasions. More serious incidents have, however, been reported from other countries. Today, measurement facilities have been installed at the entrances to virtually all German foundries and larger scrap yards. These measurement facilities allow the swift measurement of whole lorry or freight car loads. The lower limit of detection is for some devices as low as ca. 5 nSv/h (dose rate increase above background at the detector) which is achieved by very advanced hardware and software. Additionally, simplified dose rate measurements are performed by German customs officials at the eastern borders for scrap loads to be imported into Germany. When activity is detected in a load, several options exist, like e.g.: (i) sending the scrap back to the sender; (ii) allowing the whole load to be melted down; (iii) careful unloading and separating the load with the aim of localizing and removing the contamination. This paper analyses these various options after detection, discusses the role of the competent authorities and evaluates the possible radiological consequences. Realistic dose calculations show that it is possible that a person may receive doses of several mSv or even 10 mSv if precautionary measures are neglected or if a larger source is not detected at all. This paper further addresses which types and amounts of radioactivity may be detected and which conclusions can be drawn from the dose rate at the detector. The continuous increase in the number

    Off-site nuclear emergency response in Germany is divided into disaster response under the responsibility of the Laender and measures for precautionary radiation protection pursuant to the Precautionary Radiation Protection Act under the lead of federal authorities. Early countermeasures at the regional level require a different management than long-term and comprehensive actions of precautionary radiation protection. As situations may arise in which measures of both approaches overlap with regard to place and time, it is essential to make thorough preparations in order to avoid problems with implementation.

    Final disposal of radioactive waste has been defined in Germany as: maintenance-free, safe emplacement of radioactive waste, time unlimited and no intention of retrievability. The responsibility for final disposal lies in the hands of the German Federal Government, which has assigned a federal authority to plan, erect and operate the federal facilities for long-term storage of nuclear waste. The federal authority has in lack of industrial experience contracted my company DBE which is responsible for the engineering, erection and operation of all German nuclear waste repositories.

    The transportation sector is one of the first responsible of the air pollution in Germany. The kyoto protocol and the european directive led the german Government to set about some measures. To encourage the petroleum industry to develop classical fuels/biofuels mixing, the government exempted from taxes until 2020 the biofuels part. The Government decided also financial incentives for diesel vehicles equipped with particles filters. Among the different fuels, the document presents the advantages and disadvantages of the hydrogen fuels and the hybrid motors. (A.L.B.)

    Full Text Available Germany’s educational system has undergone a series of transformations during the last 40 years. In recent years, marked increases in enrolment have occurred. In response, admission requirements have been relaxed and new universities have been established.Academic distance education in the former Federal Republic of Germany (West Germany was ushered in by the educational radio broadcasts around the end of the 1960s. Aside from the formation of the FernUniversität (Open University in West Germany in 1975, there were significant developments in distance education occurring at the major universities in the German Democratic Republic (East Germany. After German reunification in 1990, the new unitary state launched programs to advance the development of distance education programs at conventional universities.Germany’s campus-based universities (Präsenzuniversitäten created various entities, including central units and consortia of universities to design and market distance education programs. Hybridisation provides the necessary prerequisites for dual mode delivery, such as basic and continuing education programs, as well as for the combination of distance and campus-based education (Präsenzstudium. Hybridisation also has also opened the door for the creation of new programs.Following an initial phase in which distance education research is expected to centralize a trend towards decentralisation is likely to follow. The German Association for Distance Education (AG-F offers a viable research network in distance education. Two dual mode case studies are also be surveyed: The Master of Arts degree, offered by the University of Koblenz-Landau, with Library Science as the second major, and the University of Kaiserslautern, where basic education will continue to be captured within the domain of the Präsenzstudium or campus-based education.The area in which distance education is flourishing most is within the field of academic continuing

  13. Sea level report

    International Nuclear Information System (INIS)

    Schwartz, M.L.

    1979-01-01

    Study of Cenozoic Era sea levels shows a continual lowering of sea level through the Tertiary Period. This overall drop in sea level accompanied the Pleistocene Epoch glacio-eustatic fluctuations. The considerable change of Pleistocene Epoch sea level is most directly attributable to the glacio-eustatic factor, with a time span of 10 5 years and an amplitude or range of approximately 200 m. The lowering of sea level since the end of the Cretaceous Period is attributed to subsidence and mid-ocean ridges. The maximum rate for sea level change is 4 cm/y. At present, mean sea level is rising at about 3 to 4 mm/y. Glacio-eustacy and tectono-eustacy are the parameters for predicting sea level changes in the next 1 my. Glacio-eustatic sea level changes may be projected on the basis of the Milankovitch Theory. Predictions about tectono-eustatic sea level changes, however, involve predictions about future tectonic activity and are therefore somewhat difficult to make. Coastal erosion and sedimentation are affected by changes in sea level. Erosion rates for soft sediments may be as much as 50 m/y. The maximum sedimentation accumulation rate is 20 m/100 y

    The Dead Sea Region is an exceptional ecosystem whose seismic activity has influenced all facets of the development, from ground water availability to human evolution. Israelis, Palestinians and Jordanians living in the Dead Sea region are exposed to severe earthquake hazard. Repeatedly large earthquakes (e.g. 1927, magnitude 6.0; (Ambraseys, 2009)) shook the whole Dead Sea region proving that earthquake hazard knows no borders and damaging seismic events can strike anytime. Combined with the high vulnerability of cities in the region and with the enormous concentration of historical values this natural hazard results in an extreme earthquake risk. Thus, an integration of earthquake parameters at all scales (size and time) and their combination with data of infrastructure are needed with the specific aim of providing a state-of-the-art seismic hazard assessment for the Dead Sea region as well as a first quantitative estimate of vulnerability and risk. A strong motivation for our research is the lack of reliable multi-parameter ground-based geophysical information on earthquakes in the Dead Sea region. The proposed set up of a number of observatories with on-line data access will enable to derive the present-day seismicity and deformation pattern in the Dead Sea region. The first multi-parameter stations were installed in Jordan, Israel and Palestine for long-time monitoring. All partners will jointly use these locations. All stations will have an open data policy, with the Deutsches GeoForschungsZentrum (GFZ, Potsdam, Germany) providing the hard and software for real-time data transmission via satellite to Germany, where all partners can access the data via standard data protocols.

  15. The herbicide Glyphosate affects nitrification in the Elbe estuary, Germany

    Sanders, Tina; Lassen, Stephan

    2015-04-01

    The Elbe River is one of the biggest European rivers discharging into the North Sea. It also transports high amounts of nutrients and pollutants like pesticides. Important source regions of both nutrients and pollutants are located within the river catchment, which is dominated by agricultural land-use. From these agricultural soils, pesticides can be carried via the river and estuary into the North Sea. Glyphosate (N-(phosphonomethyl) glycine) is the most commonly used herbicide worldwide and mainly used to regulate unwanted plant growth and for the expedition of crop ripening. In Germany, ~ 6000 tons of glyphosate are applied yearly in agriculture and private use. Glyphosate is degradable by microorganisms and has a half-life in water of 35 to 60 days. This herbicide specifically inhibits 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), an enzyme that catalyzes the biosynthesis of essential aromatic amino acids in plants, fungi, and bacteria. Nitrifying bacteria, which play an important role in the internal nitrogen cycling in the Elbe estuary, also possess this enzyme. The aim of our study was to quantify the concentration of glyphosate in water and sediment samples of the Elbe to get an overview about relevant environmental levels and to assess the impact of glyphosate on inhibition of nitrifying activities. To quantify the effect of glyphosate on nitrification activity, natural samples as well as pure cultures of Nitrosomonas europea (strain Nm50) were incubated with different concentrations of glyphosate over a period of some weeks. The nitrifying activity was determined according to changes of the nitrite and nitrate concentration as well as the cell number. Glyphosate was detectable in water and sediment samples in the Elbe estuary with up to 5 ppb mainly in the Port of Hamburg region. In both incubation experiments an inhibiting effect of glyphosate on nitrification could be shown. The incubated natural water sample was affected by a glyphosate

  16. Reversing course: Germany`s response to the challenge of transboundary air pollution

    Energy Technology Data Exchange (ETDEWEB)

    1998-03-01

    Perhaps like no other country, Germany has radically changed its policies towards regulating air pollution in the European context. Acting originally as a dragger in the 1970s to regulate transboundary air pollutants due to pessimism about the relationship between causes and effects, Germany responded very decisively to its own damage assessment in the early 1980s. In particular the adverse effects to forests (`Waldsterben` or forest decline) led to the formulation of strict air pollution regulations in the domestic context, efforts to spread the regulatory system within the European Union, and activities within the United Nations Economic Commission for Europe to foster stronger, continent-wide emission reductions. Using three conceptual models (rational actor, domestic politics, and social learning), we show that Germany deviated strongly from the ideal policy cycle consisting of (i) domestic policy formulation, (ii) international negotiations, as well as (iii) implementation and compliance with the provisions of international environmental agreements. Both national policy-making as well as partial implementation have been well on the way towards compliance even before Germany entered international negotiations on substantive protocols. Therefore, one may conclude from this country study that push countries may use the results of their national policy processes to influence the policy of other countries. (orig.)

    Brücher, T.; Ulbrich, U.

    2003-04-01

    A transient low resolution (T42) greenhouse gas run of the ECHAM4/OPYC3 GCM, and a nested run of the regional climate model HIRLAM/RCA1 (40 km resolution) are considered with respect to summer rainfall. The area of investigation is the flat part (< 200 m above sea level) of North Rhine-Westphalia, Germany, and the model grid points close to / within this area, respectively. For the time period representing present day climate, the precipitation amounts simulated by the GCM are in good agreement with oberserved values, whereas the nested regional model produces too large rainfall sums (+25%). With respect to intensity classes on a daily basis, both models underestimate the observed frequency of intense events and overestimate the number of days with a low precipitation amount. For the GCM, we take account of these systematic errors by defining a non-linear transfer function. This function is subsequently applied to the model's output from the scenario period. For future climate, both models show a significant reduction of the total summer precipitation. This reduction is caused by an increased number of dry days, which eventually dominates over a simultaneous increase in the number of days with intense precipitation. Average rainfalls are computed for periods between 5 to 30 days. For all averaging periods considered. The frequency of periods with less than 2 mm precipitation per day is found to rise (by up to 200%) compared to present day climate. There are less periods with more than 3 mm of rain. The decline amounts up to 50%. Thus, the models give no evidence for a grouping of heavy rainfall events.

  3. Maternal employment and childhood overweight in Germany.

    Meyer, Sophie-Charlotte

    2016-12-01

    A widespread finding among studies from the US and the UK is that maternal employment is correlated with an increased risk of child overweight, even in a causal manner, whereas studies from other countries obtain less conclusive results. As evidence for Germany is still scarce, the purpose of this study is to identify the effect of maternal employment on childhood overweight in Germany using two sets of representative micro data. We further explore potential underlying mechanisms that might explain this relationship. In order to address the selection into maternal full-time employment, we use an instrumental variable strategy exploiting the number of younger siblings in the household as an instrument. While the OLS models suggest that maternal full-time employment is related to a 5 percentage point higher probability of the child to be overweight, IV estimates indicate a 25 percentage points higher overweight probability due to maternal full-time employment. Exploring various possible pathways, we find that maternal full-time employment promotes unhealthy dietary and activity behavior which might explain the positive effect of maternal employment on child overweight to some extent. Although there are limitations to our IV approach, several sensitivity analyses confirm the robustness of our findings. Copyright © 2016 Elsevier B.V. All rights reserved.

    1996-12-31

    By the end of 1995 in total 3655 wind turbines (WT`s) were installed in Germany with a total capacity of 1,136 MW. In the year 1995 alone the WT installations grew by 1,070 units with 505 MW. About 40% of the 1995 installations were sold to inland states of Germany with their lower wind speed potential. This fast development occurred in parallel to continuously reduced local state and federal subsidies. The further development is based mainly on the guaranteed reimbursement due to the Electricity Feed Law. But since some time the electricity utilities fight back on all legal and political levels to get cancelled the unloved Electricity Feed Law and since two years the building construction law with the foreseen privilege for WT`s is discussed without any result. All these difficulties affect investors and credit giving banks in such a negative way, that the further annual increase in wind power installation for 1996 could be 10 to 20% less than in 1995. Many of the new commercial Megawatt WT`s have pitch control and variable rotor speed which cause better electrical power quality and lower life time loads. From statistical evaluations on technical data of WT`s a good overview of the further development is derived. 8 refs., 10 figs.

    Full Text Available The article deals with one of the causes of dissolution/breakdown of Yugoslavia. The author first analyses writing of German and Austrian press which has, at the very beginning of the crisis, taken a strong anti-Serb standing, as in 1914 and 1941. Author then analyses the reasons that led Austrian and German diplomacy and governments to actively forging the crisis and then breaking down a sovereign country. Those reasons could be summarized as follows: German and Austrian revenge for two wars lost in these territories; improvement of conditions for fulfillment of old German dream to advance toward Middle East; in order to become a world power Germany 'had to' to annul some of the consequences of the First and Second World War on the symbolic level and acquire a possibility to test its powers, and breaking down Yugoslavia, with help of its internal allies Germany broke down its army without military engagement and removed an obstacle for advancement towards East.

    East Germany fibers producer Thuringische Faser AG Schwarza (TFS; Rudolstadt) is entering the polyethylene terephthalate (PET) business. The company, owned by India's Dalmia Group (New Delhi), is building an 80,000-m.t./year PET granulate plant, one of the largest in Europe, for completion at the end of 1995. The product will be used to make PET bottles and film for food packaging. TFS will need to buy 70,000 m.t./year of purified terephthalic acid and 27,000 m.t./year of ethylene glycol to feed the new plant. When acquiring TFS, Dalmia's chairman, Sanjay Dalmia, pledged to invest DM150 million ($95.4 million) in the Germany firm and keep 1,200 of the 3,000 workers. John Brown Deutsche Engineering (Essen) has been awarded a contract covering engineering, know-how, and turnkey supply of the complete plant, and will share of the complete plant, and will share the work with Austrian associate, Voest John Brown Industrieanlagenbau (Linz). The company, which completed against Zimmer (Frankfurt), will use its own technology. TFS, with 1992 sales of DM120 million, has capacities to produce 20,000 m.t/year of viscose staple fiber, 18,000 m.t./year of nylon-6 filament yarn, and 6,300 m.t./year of textile-grade polyester granulate, which will be converted to produce bottle-grade PET

    Since 1990 the percentage of smokers among the 12 to 17-year-olds in Germany has risen from 21 % to about 28 %. Most of them start between the age of 11 and 13. 85 % favour a certain brand by the age of 18. Despite the prohibition of tobacco commercials on radio and TV the cigarette industry has continually increased their budget for advertising aimed more and more at women and children. According to the author's knowledge, this report describes for the first time the strategies most frequently applied in Germany to incite children and teenagers to smoking. The publicity campaigns are not restricted to billboards and the printed press, but use the internet also. Indirect conditioning to a certain brand by music videos, movies and merchandising of attractive clothes and trips as well as the sponsoring of special music and sports events are also shown.The report analyses and evaluates examples of messages in printed advertisements aimed at children. With psychological skill interest in smoking is created with teenagers and a conditioning for smoking in certain situations is promoted.

    As a contribution to Germany's "Science Year 2016*17 - Seas and Oceans", a large science outreach program organized and financed by the National Ministry for Education and Research, GeoUnion, the umbrella organization of Earth science associations and institutions in Germany, has conducted a series of advance level workshops for out-of-school educators and interpreters in Germany. The workshops were organized in co-operation with geoparks, biosphere reserve areas and other environmental management institutions all over Germany. The goal was to convey various perspectives of modern marine sciences to inland venues, linking important present-day marine themes with the presentation of marine phases in the geological history of the host region. The workshops were designed for park rangers, museum educationalists and other science communicators, initiating a broader impact on target groups such as school classes, (geo-)tourists and stakeholder groups. Our approach has been to combine lectures by top-level scientists (on both ocean literacy aspects and regional geology) with discussions and an on-the-spot learning-and-presenting module based on prepared text and visual material. Beyond earth science issues we have integrated economy, ecology, social sciences as well as arts and humanities aspects. One central topic was the role of the world ocean in climate change; other themes highlighted sea level rise, the thermohaline circulation, sea-floor spreading, coral reefs, over-fishing, various marine species and the problem of plastic waste in the ocean. We had anticipated that marine issues are actually very rarely discussed in inland Germany. A structured presentation of ocean literacy elements has proved to be a new range of topical issues from earth and environmental sciences highly appreciated by the participants.

  12. Contemporary Arctic Sea Level

    Science.gov (United States)

    Cazenave, A. A.

    2017-12-01

    During recent decades, the Arctic region has warmed at a rate about twice the rest of the globe. Sea ice melting is increasing and the Greenland ice sheet is losing mass at an accelerated rate. Arctic warming, decrease in the sea ice cover and fresh water input to the Arctic ocean may eventually impact the Arctic sea level. In this presentation, we review our current knowledge of contemporary Arctic sea level changes. Until the beginning of the 1990s, Arctic sea level variations were essentially deduced from tide gauges located along the Russian and Norwegian coastlines. Since then, high inclination satellite altimetry missions have allowed measuring sea level over a large portion of the Arctic Ocean (up to 80 degree north). Measuring sea level in the Arctic by satellite altimetry is challenging because the presence of sea ice cover limits the full capacity of this technique. However adapted processing of raw altimetric measurements significantly increases the number of valid data, hence the data coverage, from which regional sea level variations can be extracted. Over the altimetry era, positive trend patterns are observed over the Beaufort Gyre and along the east coast of Greenland, while negative trends are reported along the Siberian shelf. On average over the Arctic region covered by satellite altimetry, the rate of sea level rise since 1992 is slightly less than the global mea sea level rate (of about 3 mm per year). On the other hand, the interannual variability is quite significant. Space gravimetry data from the GRACE mission and ocean reanalyses provide information on the mass and steric contributions to sea level, hence on the sea level budget. Budget studies show that regional sea level trends over the Beaufort Gyre and along the eastern coast of Greenland, are essentially due to salinity changes. However, in terms of regional average, the net steric component contributes little to the observed sea level trend. The sea level budget in the Arctic

    The technologies developed in West Germany for radioactive waste management are widely reviewed. The first topic in this review paper is the disposal of low- and middle-level radioactive liquid wastes. Almost all these liquid wastes are evaporated, and the typical decontamination factor attained is 10/sup 4/ -- 10/sup 6/. The second topic is the solidification of residuals. Short explanation is given to bituminization and some new processes. The third topic is high-level liquid wastes. Degradation of glass quality due to various radiation is discussed. Embedding of small glass particles containing radioactive wastes into metal is also explained. Disposals of low-level solid wastes and the special wastes produced from reprocessing and mixed oxide fuel fabrication are explained. Final disposal of radioactive wastes in halite is discussed as the last topic. Many photographs are used to illustrate the industrial or experimental use of those management methods.

    The discussion is limited to nuclear air cleaning activities in the Federal Republic of Germany. Work is underway on containment venting with regard to filtration based on a combination of stainless steel roughing and fine filters with a decontamination factor similar to or better than that achieved with high-efficiency particulate air filters. The main point of interest is the development of relatively small filter units that can be located inside the containment. The concept of a new design for double containment having annular rooms between the steel containment and the concrete containment is discussed. Work related to the dismantling of decommissioned reactors and limited research for fuel reprocessing facilities are also noted

    In this book the author comments and discusses the content, successes and failures, uncertainties and consequences of the new German energy policy, Energiewende. The objective is to reach 80 to 95 per cent of reduction of greenhouse gas emissions by 2050 while phasing out nuclear. The author denies some statements about this policy. Some say that coal will replace nuclear as in fact renewable electricity production more than compensates the reduction of nuclear electricity production. Others say that Germany will have to import French nuclear electricity as in fact France must import German electricity in case of peak consumptions. Others say that German electricity became more expensive: it's true but it is in fact compensated by much higher energy savings. Remaining issues are the financing of nuclear plant dismantling and of nuclear waste management, the organisation of a decentralised production network, and the passage to renewable energies in the heating and transport sectors

    Child Soldiers as Refugees in Germany How do former child soldiers cope with their potentially traumatic experiences, and how do the living conditions as refugees influence these coping processes? A dissertation at the faculty of human and social sciences at the University of Wuppertal, based on biographical-narrative interviews with 15 young refugees from six African countries, describes the characteristics of the traumatic sequences in the countries of origin and in exile, and elaborates typical coping processes. In order to survive a situation of absolute subjection within armed groups, children develop forms of adequate adaptation to the context like regulation and detachment of emotions e.g. with the use of drugs, assimilation to an idea of "hard masculinity" etc. They become victims, witnesses and often perpetrators of extreme violence (man-made-disaster), respectively traumatic processes can be seen in all sequences. After leaving the armed groups there is no way back into the families and communities destroyed by armed conflict, so they become refugees. In Germany, they are subjected to a bureaucratic and excluding asylum system, in which decisions on all relevant areas of life (age determination, place and right of residence, form of accommodation, access to education, etc.) are imposed on them. Especially the insecure right of residence and the living conditions in refugee camps are severe risk factors, impeding stabilization. Social support, e. g. by competent professionals, access to trauma- and culture-sensitive psychotherapy, societal inclusion, but also personal resilience are essential for coping with trauma and developing new future perspectives.

    Full Text Available Matthias Knutzen (born 1646 – died after 1674 was the first author we know of who self-identified as an atheist (Schröder 2010: 8. Before this, the term had solely been used pejoratively to label others. While Knutzen is almost completely forgotten now, authors such as Ludwig Feuerbach, Karl Marx, Friedrich Nietzsche, or Sigmund Freud are better remembered and might even be considered classic writers in the history of the atheist criticism of religion. Whatever may be said about the influence of any one of these authors, there is no doubt that Germany looks back on a notable history in this field. About a decade ago, Germany’s capital Berlin was even dubbed ‘the world capital of atheism’ by the American sociologist Peter L. Berger (2001: 195.Given this situation, I am bewildered by the expression ‘New Atheism’. Yet, undoubtedly, the term has become a catchphrase that is commonly used in the public discourse of several countries. The most prominent authors to be labelled ‘New Atheists’ are Richard Dawkins (The God Delusion, 2006, Daniel Dennett (Breaking the Spell: Religion as a Natural Phenomenon, 2006, Sam Harris (The End of Faith: Religion, Terror, and the Future of Reason, 2004, and Letter to a Christian Nation, 2006, and Christopher Hitchens (God Is Not Great: How Religion Poisons Every­thing, 2007. These authors and their books – all of them international bestsellers – have been intensely discussed around the world, including in Germany. In this paper, I intend to illuminate some of the characteristics and remarkable traits of the German discourse on the ‘New Atheism’. Here we can distinguish between two phases. The German media initially characterised ‘New Atheism’ as a rather peculiarly American phenomenon. However, it soon came to be understood to be a part of German culture as well.

    The incidence of skin cancer is increasing worldwide. For decades, opportunistic melanoma screening has been carried out to respond to this burden. However, despite potential positive effects such as reduced morbidity and mortality, there is still a lack of evidence for feasibility and effectiveness of organized skin cancer screening. The main aim of the project was to evaluate the feasibility of systematic skin cancer screening. In 2003, the Association of Dermatological Prevention was contracted to implement the population-based SCREEN project (Skin Cancer Research to Provide Evidence for Effectiveness of Screening in Northern Germany) in the German state of Schleswig-Holstein. A two-step program addressing malignant melanoma and nonmelanocytic skin cancer was implemented. Citizens (aged ≥ 20 years) with statutory health insurance were eligible for a standardized whole-body examination during the 12-month study period. Cancer registry and mortality data were used to assess first effects. Of 1.88 million eligible citizens, 360,288 participated in SCREEN. The overall population-based participation rate was 19%. A total of 3103 malignant skin tumors were found. On the population level, invasive melanoma incidence increased by 34% during SCREEN. Five years after SCREEN a substantial decrease in melanoma mortality was seen (men: observed 0.79/100,000 and expected 2.00/100,000; women: observed 0.66/100,000 and expected 1.30/100,000). Because of political reasons (resistance as well as lack of support from major German health care stakeholders), it was not possible to conduct a randomized controlled trial. The project showed that large-scale systematic skin cancer screening is feasible and has the potential to reduce skin cancer burden, including mortality. Based on the results of SCREEN, a national statutory skin cancer early detection program was implemented in Germany in 2008. Copyright © 2010 American Academy of Dermatology, Inc.

  7. Germany's climate policy: Facing an automobile dilemma

    Germany has one of the most ambitious climate policy goals worldwide, having pledged to reduce national emissions by 40% by 2020, and 80–95% by 2050 (base year: 1990). 2015 data suggests that progress on decarbonisation has slowed, also because emissions from the transport sector have grown. Road transport, which is contributing 20.5% to Germany's CO_2 emissions, has become a major obstacle to achieving the country's policy goals. This paper analyses energy use from road transport in order to provide a better understanding of emissions from this sub-sector. Data is derived from representative longitudinal household surveys as well as mobility and fuel diaries for the period 2002–2015. Analysis reveals significant growth in energy-inefficient car choices, as well as considerable differences in mobility patterns (distances driven, driving styles) and actual fuel consumption between car segments. Findings suggest that German transport policies will fail to deliver significant emission reductions if complexities in car model choices and use patterns are ignored. Both command-and-control and market-based measures will be needed to align the transport sector with climate goals, while persisting policy inconsistencies will also have to be addressed. Findings are of central relevance for EU-wide and global climate policy in the transport sector. - Highlights: • Emissions from German road transport have remained constant between 1990 and 2015. • Non-progress on transport decarbonisation is barrier to national mitigation goals. • Analysis shows that wide range of complexities are overlooked by government. • Policies need to consider car fleet segmentation and driving patterns. • Command-and-control as well as market-based measures needed.

  8. Strategy for decommissioning of NPP's in Germany

    2003-01-01

    According to German Atomic Law, two different strategies are possible, i.e. direct dismantling and safe enclosure before dismantling. Both approaches have their advantages and disadvantages. Taking into account the site and plant specific conditions the optimal strategy can be evaluated. Both approaches have been applied in Germany in the past. The German Atomic Law and the Radiation Protection Ordinance (June 2002) were adapted recently (July 2002). Additionally, the life operation time of the German NPP's was fixed in a new law (April 2002): Orderly Termination of the Commercial Production of Nuclear Electricity. These issues have made it necessary for the power utilities to review the strategies applied. As long as the final disposal in Germany is still an open issue, the construction of local Interim Stores is necessary to be able to dismantle a NPP. The basic strategies are not excluding each other and it seems clear today, that the optimal approach is a combination of these strategies, e.g. dismantling of all auxiliary systems and leaving activated parts for a longer SE period. Within this approach the advantages of both basic strategies have been integrated in one. The EWN GmbH has developed such integrated but still different approaches for the decommissioning projects of the Kernkraftwerke Greifswald (KGR) and the Arbeitsgemeinschaft Versuchsreaktor (AVR) Juelich. It can be stated that the decommissioning of a NPP does not present technical issues of concern, but is more a project management issue, although surrounded by sometime intricate political and juridical boundary conditions. A major strategy change is to be expected only when final disposal capacities are available in the future. (authors)

  9. Reflexions on Urban Gardening in Germany

    Directory of Open Access Journals (Sweden)

    Evelyn Gustedt

    2016-04-01

    Full Text Available This article reflects on traditional and contemporary gardening movements in Germany. The focus is on forms of gardening, that take place in spaces subject to land lease agreements and similar forms of tenancy or of illegal land take or squatting. The author examines various definitions taking into account the variety of practices, the development of urban gardening over time, and the respective backgrounds or values that users relate to such gardening activities. The examination of definitions led to the drawing up of a timeline of traditional and contemporary gardening movements in Germany and to the tentative approaching of this issue from a semantic perspective. The latter is due to the usage of many different terms mostly as yet undefined in a legal sense. Translation into English or, most likely, to any other language, further blurs the common understanding of the terms used. The author concludes with some considerations on these gardening movements in relation to urban sustainable developments. A presentation at the 5th Rencontres Internationals de Reims on Sustainability Studies, dedicated to Urban Agriculture – Fostering the Urban-Rural Continuum, which took place in October 2015 in Reims/France was the starting point of this article. The basis of this article is a literature review, nourished to a certain extent by observations randomly made over many years and complemented through talks with competent young colleagues. Special thanks go to Martin Sondermann, Leibniz University Hannover, who shared his research experience in various discussions with the author, as well as to Friederike Stelter, internship student at the author’s place of work, who gave highly appreciated support to the preparation of the presentation.

  10. Persistent Educational Advantage Across Three Generations: Empirical Evidence for Germany

    2016-12-01

    Full Text Available This article uses survey data from the German Socio-Economic Panel (GSOEP to analyze the persistence of educational attainment across three generations in Germany. I obtain evidence of a robust effect of grandparents' education on respondents' own educational attainment in West Germany, net of parental class, education, occupational status, family income, parents' relationship history, and family size. I also test whether the grandparent effect results from resource compensation or cumulative advantage and find empirical support for both mechanisms. In comparison, the intergenerational association between grandparents' and respondents' education is considerably weaker in East Germany and is also mediated completely by parental education. There are hardly any gender differences in the role of grandparents for respondents’ educational attainment, except for the fact that resource compensation is found to be exclusively relevant for women’s attainment in both West Germany and in East Germany after German reunification and the associated transition to an open educational system.

    "The paper investigates the interrelationship between fertility and infant mortality and its economic determinants by time-series methods for historical and modern Germany. It is studied whether the causal effects of infant mortality on fertility have to be considered as hoarding or replacement, and whether the costs of nutrition have an influence on family decision making about demographic variables. Results show that there are indications for replacement motives, and that economic factors matter." (SUMMARY IN FRE AND ITA) excerpt

    A numerical, density dependent groundwater model is set up for the North Sea Island of Borkum to estimate climate change impacts on coastal aquifers and especially the situation of barrier islands in the Wadden Sea. The database includes information from boreholes, a seismic survey, a helicopter-borne electromagnetic (HEM) survey, monitoring of the freshwater-saltwater boundary by vertical electrode chains in two boreholes, measurements of groundwater table, pumping and slug tests, as well as water samples. Based on a statistical analysis of borehole columns, seismic sections and HEM, a hydrogeological model is set up. The groundwater model is developed using the finite-element programme FEFLOW. The density dependent groundwater model is calibrated on the basis of hydraulic, hydrological and geophysical data, in particular spatial HEM and local monitoring data. Verification runs with the calibrated model show good agreement between measured and computed hydraulic heads. A good agreement is also obtained between measured and computed density or total dissolved solids data for both the entire freshwater lens on a large scale and in the area of the well fields on a small scale. For simulating future changes in this coastal groundwater system until the end of the current century, we use the climate scenario A2, specified by the Intergovernmental Panel on Climate Change and, in particular, the data for the German North Sea coast. Simulation runs show proceeding salinisation with time beneath the well fields of the two waterworks Waterdelle and Ostland. The modelling study shows that the spreading of well fields is an appropriate protection measure against excessive salinisation of the water supply until the end of the current century.

  19. Virulence Profiles of Vibrio vulnificus in German Coastal Waters, a Comparison of North Sea and Baltic Sea Isolates

    2015-12-01

    Full Text Available Vibrio vulnificus is a halophilic bacterium of coastal environments known for sporadically causing severe foodborne or wound infections. Global warming is expected to lead to a rising occurrence of V. vulnificus and an increasing incidence of human infections in Northern Europe. So far, infections in Germany were exclusively documented for the Baltic Sea coast, while no cases from the North Sea region have been reported. Regional variations in the prevalence of infections may be influenced by differences in the pathogenicity of V. vulnificus populations in both areas. This study aimed to compare the distribution of virulence-associated traits and genotypes among 101 V. vulnificus isolates from the Baltic Sea and North Sea in order to assess their pathogenicity potential. Furthermore, genetic relationships were examined by multilocus sequence typing (MLST. A high diversity of MLST sequences (74 sequence types and differences regarding the presence of six potential pathogenicity markers were observed in the V. vulnificus populations of both areas. Strains with genotypes and markers associated with pathogenicity are not restricted to a particular geographic region. This indicates that lack of reported cases in the North Sea region is not caused by the absence of potentially pathogenic strains.

    Full Text Available Overall progress recorded in contemporary society, has increased at the same time the aspirations and expectations of the population, marked by phenomena which are based on the financial policy of the Executive. Of course, for the legislature to know the financial activity carried out by the Executive Board, in each State was established a Supreme Audit Institution (SAI, whose independence is guaranteed by the Constitution, as it is in Germany, or by law, as is the case of the United Kingdom. The variety of powers of supreme audit, is the result of various economic areas, each demonstrations through specific activities and suitable approaches to organizational cultures, which gives them their distinct identities. The work is conducted under the public responsibility with an emphasis on developing and improving continuously audit methodologies to present best practices. The two supreme institutions operate according to an annual plan of action which includes financial audit or regularity and performance auditing actions, and additional Federal Court of Audit of Germany practice preventive control institutions contained in its area of activity. By tradition, the role of supreme consists of the evaluation as regards the legality and regularity of financial management and accounting, but since the 80's but it was noticeable trend internationally to audit performance or "value for money" (United Kingdom, since the latter refers to the essence of the problem and is the final attainment of the envisaged at the time of allocation of resources. The topic researched is distinguished by originality, marked being the fact that a area so important as that of external public audit is least known works, and I wish to point out the vacuum bibliographic Supreme Audit Institutions experience in the international arena and beyond. Research methodology consists in the evaluation of resources in the area, using foreign literature. For the study of the subject of

    A study trip to a biomass gasification plant in Germany took place from 13-15 November 2000. The goal of the trip was to obtain information on German developments, experience, and possibilities in the field of biomass gasification. The participants were representatives of Dutch parties in the energy sector: waste sector, manufacturers, producers, policy makers and consultants. The most important feature was the visit to plants that were in operation. Due in particular to the new EEG (Emeuerbare-Energien-Gesetz/Renewable Energy) legislation, German policy makers have created an initial market for sustainable energy with a degree of success. The key feature is that EEG makes projects 'bankable' by guaranteeing a return delivery compensation. An EEG-type scheme designed to accelerate the development of sustainable energy could be an interesting instrument also for the Netherlands. The plan was to visit four plants and have a number of presentations in a period of three days. Preference was for relatively new plants with differing concepts. The following plants were visited and/or presented: 200-kWe CHP wood gasification plant, based on AHT technology, located at Domsland in Eckenfoerde; a 10,000 tonnes/year wood gasification plant, based on 'cupola furnace' technology of blast furnaces, located at Holzhausen near Leipzig; a 1-MWe wood gasification plant, based on Carbo-V technology, located at Freiberg; and finally a 23-MWe CBP wood gasification plant, also based on Juch technology, located at Siebenlehn. In clearly appears that Germany is ahead of the Netherlands in the realisation of gasification plants. Still, there are certain problems with the reliability of operation. The plants selected were relatively new (with the possible exception of Espenhain) and they are having too many teething problems. Sound insight has been obtained into the various concepts of decentralised energy generation from biomass and how this can be fitted into the existing infrastructure

    In Germany, natural gas faces stiff competition from other types of energy. In many applications, natural gas is capable of replacing other fuels. In addition there is a growing gas-to-gas competition in some European countries, either through pipeline construction by a competitor as in Germany or by mandatory third-party access as in UK. Competition leads to market value-oriented energy pricing, which is particularly evident in Germany. For the consumer, this competitive situation ensures that natural gas can be obtained (and remains available in the long term) at competitive prices

    Strokes are one of the leading causes of morbidity and mortality worldwide and the main reason for longterm care dependency in Germany. Concerning the economical impact on patients and healthcare systems it is of particular importance to prevent this disease as well as to improve the outcome of the affected persons. Beside the primary well-known risk factors like hypertension, cigarette smoking, physical inactivity and others, also weather seems to have pronounced influence on the occurrence and frequency of strokes. Previous studies most often focused on effects of singular meteorological variables like ambient air temperature, air pressure or humidity. An advanced approach is to link the entire suite of daily weather elements classified to air mass- or weather types to cerebrovascular morbidity or mortality. In a joint pilot study bringing together climatologists, environmental scientists and physicians from the University of Augsburg and the clinical centre Augsburg, we analysed relationships between singular meteorological parameters as well as combined weather effects (e.g. weather types) and strokes in the urban area of Augsburg and the surrounding rural region. A total of 17.501 stroke admissions to Neurological Clinic and Clinical Neurophysiology at Klinikum Augsburg between 2006 and 2015 are classified to either "ischaemic" (16.354) or "haemorrhagic" (1.147) subtype according to etiology (based on the International Classification of Diseases - 10th Revision). Spearman correlations between daily frequencies of ischaemic and haemorrhagic strokes and singular atmospheric parameters (T, Tmin, Tmax, air pressure, humidity etc.) measured at the DWD (German weather service) meteorological station at Augsburg Muehlhausen are rather low. However, higher correlations are achieved when considering sub-samples of "homogenous weather conditions" derived from synoptic circulation classifications: e.g. within almost all of 10 types arising from a classification of

    In June 2006, FOI published the report: Sweden and the NEGP: a Pilot Study of the North European Gas Pipeline and Sweden's Dependence on Russian Energy, a base data report on a topic that FOI considered to be of rising importance. Much has happened since then and the NEGP has changed its name to Nord Stream and submitted an official notification on the intention of realising the project of constructing a gas pipeline from Russia to Germany via the Baltic Sea. The primary aim of this report is to discuss and analyse some of the core aspects of Nord Stream and the pipeline project with regard to the security situation for the Baltic Sea region. The report constitutes an updated version of the previous report. Most of the old report still stands valid, especially concerning the historical survey of Russia's energy policy, but the new report has additional chapters and is broader in scope concerning the consequences of the project

    There is high need for more research in the field of rare diseases. Not only must the causes and mechanisms of the numerous and often heterogeneous diseases be delineated, but criteria must also be defined for optimal stratification of patients for individualized therapies. In this context, research and innovative diagnostics are linked together more closely than in other fields of medicine. The early stages of disease-oriented research can be performed in individual institutions but, due to low numbers of patients, late translation and transfer into clinics requires multicentric and international collaboration. In Germany research on rare diseases takes place mostly in faculties of medicine at universities. Since the institutional financial support is very low, research grants have substantial significance. The German Research Foundation (DFG) and the Federal Ministry of Education and Research (BMBF) are the main grant agencies for national projects, but foundations and patient advocacy groups also finance research to a certain extent. The ERA-Net "E-Rare" and the programs of the EU target primarily international cross-border projects and patient trials. All of these programs need to be adapted more efficiently to the particular needs of rare disease research. For national and international research projects on rare diseases, sufficient funds are needed but also sustainable interdisciplinary platforms and centers must be established in order to share expert knowledge and to implement complex programs such as proof-of-concept studies in humans.

    Traumatic experiences resulting from war and violence can lead to a broad spectrum of psychological and somatic stress responses. The psychological strain of traumatized refugees is frequently aggravated by specific post-migration stressors. The current healthcare provision in Germany is characterized by many restrictions. The different residence permits are associated with a limited access to medical and psychotherapeutic services. In addition, there are several barriers limiting access of this group of patients to the healthcare system (e. g. low level of training of mental healthcare staff, language barriers and lack of financing for interpreters). Empirical studies have shown that traumatized refugees profit from existing trauma-focused and evidence-based interventions. Treatment is associated with particular challenges and issues (e. g. use of interpreters, migration and culture-specific as well as legal aspects). Specialized treatment centers for traumatized refugees use a multidisciplinary treatment approach, which includes psychotherapeutic, medical and social work interventions as well as assistance with the residential status and integration programs.

  9. Surface mining and land reclamation in Germany

    Energy Technology Data Exchange (ETDEWEB)

    Nephew, E.A.

    1972-05-01

    Mining and land restoration methods as well as planning and regulatory procedures employed in West Germany to ameliorate environmental impacts from large-scale surface mining are described. The Rhineland coalfield in North Rhine Westphalia contains some 55 billion tons of brown-coal (or lignite), making the region one of Europe's most important energy centers. The lignite is extracted from huge, open-pit mines, resulting in large areas of disturbed land. The German reclamation approach is characterized by planning and carrying out the mining process as one continuum from early planning to final restoration of land and its succeeding use. Since the coalfield is located in a populated region with settlements dating back to Roman times, whole villages lying in the path of the mining operations sometimes have to be evacuated and relocated. Even before mining begins, detailed concepts must be worked out for the new landscape which will follow: the topography, the water drainage system, lakes and forests, and the intended land-use pattern are designed and specified in advance. Early, detailed planning makes it possible to coordinate mining and concurrent land reclamation activities. The comprehensive approach permits treating the overall problem as a whole rather than dealing with its separate aspects on a piecemeal basis.

  10. Federal Republic of Germany: Commodities report 2003

    International Nuclear Information System (INIS)

    2004-01-01

    The Federal Institute for Geosciences and Natural Resources (BGR) has compiled the facts and figures in a commodities report for 25 years. This report summarises Germany's mineral and energy commodities trading, consumption and supply situation. After fears of shortages in the early 70s, this 25-year-period was mainly characterised by the feeling that mineral resources would always be available on the international markets in adequate quantities. And although there has been no change in the situation even up to the present day, the world markets for mineral resources are currently undergoing a structural change: the old rule of thumb that 20% of humanity in Europe, the USA and Japan consumed more than 80% of resource production is no longer valid. With India, the People's Republic of China, not to mention other heavily populated emerging countries, over half of the world's population is now involved in the demand for minerals. This means that the growth in world economic demand for natural resources is at the beginning of a new growth curve. (orig.)

    Though international trade is increasing, the significance of imported reptiles as carriers of pathogens with relevance to animal and human health is largely unknown. Reptiles imported to Germany were therefore investigated for blood parasites using light microscopy, and the detected parasites were morphologically characterized. Four hundred ten reptiles belonging to 17 species originating from 11 Asian, South American and African countries were included. Parasites were detected in 117 (29%) of individual reptiles and in 12 species. Haemococcidea (Haemogregarina, Hepatozoon, Schellackia) were found in 84% of snakes (Python regius, Corallus caninus), 20% of lizards (Acanthocercus atricollis, Agama agama, Kinyongia fischeri, Gekko gecko) and 50% of turtles (Pelusios castaneus). Infections with Hematozoea (Plasmodium, Sauroplasma) were detected in 14% of lizards (Acanthocercus atricollis, Agama agama, Agama mwanzae, K. fischeri, Furcifer pardalis, Xenagama batillifera, Acanthosaura capra, Physignathus cocincinus), while those with Kinetoplastea (Trypanosoma) were found in 9% of snakes (Python regius, Corallus caninus) and 25 % of lizards (K. fischeri, Acanthosaura capra, G. gecko). Nematoda including filarial larvae parasitized in 10% of lizards (Agama agama, Agama mwanzae, K. fischeri, Fu. pardalis, Physignathus cocincinus). Light microscopy mostly allowed diagnosis of the parasites' genus, while species identification was not possible because of limited morphological characteristics available for parasitic developmental stages. The investigation revealed a high percentage of imported reptiles being carriers of parasites while possible vectors and pathogenicity are largely unknown so far. The spreading of haemoparasites thus represents an incalculable risk for pet reptiles, native herpetofauna and even human beings.

  12. Rural areas of Eastern Germany: modern challenges

    Full Text Available After the German reunification the agricultural development of eastern territories seemed to have picked up its pace. Yet the main problems those territories are facing today hatched already in the mid-1990s. In our study we address the problems and challenges that hinder sustainable development of East German rural areas. We analyse agricultural statistics and describe the structure of agricultural enterprises, land-use, and other critical dimensions of agriculture. We discuss pros and cons of modern rural areas spatial planning policy and take a critical look at the current status of rural areas. We also put forward a number of concrete proposals aimed at the development of the area and counteracting the negative trends it is now experiencing. Even taking into account all ‘positive’ development trends that are postulated to have occurred since the unification, we underline the crucial necessity of diversification of labour forces and of changing the spatial planning policies in the rural areas of East Germany.

    The German Government has initiated a long-term transformation of the entire energy system termed Energiewende. Besides the gradual phase-out of nuclear energy by 2022, one substantial element is the complete overhaul of the Renewable Energy Sources Act (EEG). On 1 August 2014 the EEG 2014 entered into force, representing a fundamental revision of the existing support scheme for renewable electricity, primarily for PV, wind and biomass. Beyond, Germany decided to phase out nuclear power from its generation mix by 2022 and to increase its share of renewable energy to 40-45% by 2025 and 55-60% by 2035. Renewable electricity is still supported through feed-in tariffs laid down in the EEG 2014 and low interest loans but from now on complemented by tendering procedures over the coming years. Renewable heating and cooling is supported by the regulations in the Renewable Energies Heat Act (EEWaermeG), the Market Incentive Programme (MAP) governed by the Federal Office of Economics and Export Control (BAFA) and low-interest loans offered via the KfW. Numerous support schemes are available for renewable heat on state (Laender) level. Renewable transport fuels are mainly supported by a quota system (bio-fuels Quota Act = Biokraftstoffquotengesetz - BiokraftQuG), and through fiscal regulation

    Over the last ten years changes in the legal framework of the German health care system have promoted the development of new health service models to improve chronic care. Recent innovations include the nation-wide introduction of disease management programmes (DMPs), integrated care contracts, community nurse programmes, the introduction of General Practitioner (GP)-centred care contracts, and new opportunities to offer interdisciplinary outpatient care in polyclinics. The aim of this article is to describe the recent developments regarding both the implementation of new health care models by statutory health insurance companies and their evaluation. As part of a European project on the development and validation of disease management evaluation methods (DISMEVAL), we carried out a selective literature search to identify relevant models and evaluation studies. However, on the basis of the currently available evaluation and study results it is difficult to judge whether these developments have actually led to an improvement in the quality of chronic care in Germany. Only for DMPs, evaluation is legally mandatory; its methods are inappropriate, though, for studying the effectiveness of DMPs. Further study results on the effectiveness of DMPs mostly focus on the DMP Diabetes mellitus type II and show consistent improvements regarding process parameters such as regular routine examinations, adherence to treatment guidelines, and quality of life. More research will be needed to determine whether DMPs can also help reduce the incidence of secondary disease and mortality in the long term. Copyright © 2011. Published by Elsevier GmbH.

  15. Eocene lizard from Germany reveals amphisbaenian origins.

    Amphisbaenia is a speciose clade of fossorial lizards characterized by a snake-like body and a strongly reinforced skull adapted for head-first burrowing. The evolutionary origins of amphisbaenians are controversial, with molecular data uniting them with lacertids, a clade of Old World terrestrial lizards, whereas morphology supports a grouping with snakes and other limbless squamates. Reports of fossil stem amphisbaenians have been falsified, and no fossils have previously tested these competing phylogenetic hypotheses or shed light on ancestral amphisbaenian ecology. Here we report the discovery of a new lacertid-like lizard from the Eocene Messel locality of Germany that provides the first morphological evidence for lacertid-amphisbaenian monophyly on the basis of a reinforced, akinetic skull roof and braincase, supporting the view that body elongation and limblessness in amphisbaenians and snakes evolved independently. Morphometric analysis of body shape and ecology in squamates indicates that the postcranial anatomy of the new taxon is most consistent with opportunistically burrowing habits, which in combination with cranial reinforcement indicates that head-first burrowing evolved before body elongation and may have been a crucial first step in the evolution of amphisbaenian fossoriality.

    This book is an updated edition of the previous version from 2015. In this book the author comments and discusses the content, successes and failures, uncertainties and consequences of the new German energy policy, Energiewende. The objective is to reach 80 to 95 per cent of reduction of greenhouse gas emissions by 2050 while phasing out nuclear. The author denies some statements about this policy. Some say that coal will replace nuclear as in fact renewable electricity production more than compensates the reduction of nuclear electricity production. Others say that Germany will have to import French nuclear electricity as in fact France must import German electricity in case of peak consumptions. Others say that German electricity became more expensive: it's true but it is in fact compensated by much higher energy savings. Remaining issues are the financing of nuclear plant dismantling and of nuclear waste management, the organisation of a decentralised production network, and the passage to renewable energies in the heating and transport sectors

    Water covers a little more than two-thirds of the earth's surface. What is thrown into the sea from a ship may be washed up on a shore thousands of miles away; wastes discharged into the seas or into rivers flowing into them can affect marine life and possibly also the health of man. The study, prevention and control of pollution of the seas and oceans by radionuclides introduced as by-products of man's use of nuclear energy is thus of global interest. (author)

    Following its great success last year, Formula Student Germany made an even more impressive impact at the second competition held at the Hockenheimring in 2007. This time, 1400 students from 14 nations came together to present the results of their development work to 5000 visitors and sponsors. At the end, the competition was won by the team from the University of Stuttgart - and ATZ/MTZ would like to congratulate them on their victory. The special character of Formula Student, however, means that everyone has something to celebrate. The enthusiasm and commitment of the teams not only resulted in exciting racing cars and innovative overall designs but also in a fantastic atmosphere. (orig.)

    Full Text Available This study inspects if there is greater convergence with Germany amongst the Eurozone founding members and if their relations with the hegemonic economy have been more symmetrical after “euroization”. The dimensions explored are those inspired by the optimum currency areas (OCA framework. To some extent, the findings could signify if real convergence has been significantly endogenous. At the same time, to assess the relative dominance of Germany, the features against Germany are compared to those against US. In addition, the paper also appraises some aspects of economic performance to check whether economic conditions across the states have improved and converged after unification. In some convergence aspects, findings suggest remarkable convergence with Germany and across the states but also relative convergence with US. On economic performance, results indicate substantial improvements in inflation and unemployment. Amongst the founding states, Ireland has idiosyncratically shown serious divergences in a number of the convergence and performance measures.

    Full Text Available The aim of this paper is to analyse the taxation of labour income in Croatia, Belgium,Estonia, Germany and Slovakia. Having presented an outline of tax system rules, the paper shows the decomposition of the net average tax wedge for different family types and different income levels based on the OECD methodology. The results show that all observed countries apply a progressive tax schedule, apart from Germany where taxation for higher gross wages is not progressive due to a  cap on the SIC base. When it comes to a taxpayer earning an average gross wage, a Croatian single worker without children has the lowest tax burden, followed by Estonia, Slovakia, Germany and Belgium. However, as regards taxpayers earning 400% of AGW, Estonia has the smallest tax wedge, followed by Slovakia, Germany, Croatia and Belgium. Similar results are obtained by analyzing the tax wedge for couples with two children where one spouse is out of work.

    Cohort studies and biobank projects have led to public discussions in several European countries in the past. In Germany, many medium-sized studies are currently running successfully in terms of respondent rates. However, EU-wide research on general public perceptions of biobanks and cohort studies have shown that Germany is among those countries where people express the highest reluctance for providing body material and other data for research purposes. Because of early efforts of the just-initiated German National Cohort Study, we are able to begin to investigate in greater detail how various groups of people across Germany reflect and discuss the ongoing implementation of cohort studies and biobanking in Germany. Our research is based on 15 focus group discussions in four German regions, as well as on Eurobarometer poll data on biobanking.

  13. Sea Ice Ecosystems

    Science.gov (United States)

    Arrigo, Kevin R.

    2014-01-01

    Polar sea ice is one of the largest ecosystems on Earth. The liquid brine fraction of the ice matrix is home to a diverse array of organisms, ranging from tiny archaea to larger fish and invertebrates. These organisms can tolerate high brine salinity and low temperature but do best when conditions are milder. Thriving ice algal communities, generally dominated by diatoms, live at the ice/water interface and in recently flooded surface and interior layers, especially during spring, when temperatures begin to rise. Although protists dominate the sea ice biomass, heterotrophic bacteria are also abundant. The sea ice ecosystem provides food for a host of animals, with crustaceans being the most conspicuous. Uneaten organic matter from the ice sinks through the water column and feeds benthic ecosystems. As sea ice extent declines, ice algae likely contribute a shrinking fraction of the total amount of organic matter produced in polar waters.

    Shipboard, high volume air particulate samples were collected from the Black Sea atmosphere and analyzed by instrumental neutron activation analysis, atomic absorption spectrophotometry and ion chromatography for about 40 elements and ions. Concentrations of elements in the eastern and western parts of the Black Sea are different at the 95% confidence level, with lower concentrations in the eastern Black Sea. Back-trajectories and concentrations of elements in trajectory groups show that Europe accounts for more than 70% of the anthropogenic elements in the atmosphere. The average sulfate concentration was 7 μg/m 3 , which is comparable with rural sulfate levels in western Europe. Fluxes of elements from the atmosphere to the Black Sea are in good agreement with the results of similar flux calculations for other regions

    The South China Sea is poorly understood in terms of its marine biota, ecology and the human impacts upon it. What is known is most often contained in reports and workshop and conference documents that are not available to the wider scientific community. The South China Sea has an area of some 3.3 million km2 and depths range from the shallowest coastal fringe to 5377 m in the Manila Trench. It is also studded with numerous islets, atolls and reefs many of which are just awash at low tide. It is largely confined within the Tropic of Cancer and, therefore, experiences a monsoonal climate being influenced by the Southwest Monsoon in summer and the Northeast Monsoon in winter. The South China Sea is a marginal sea and, therefore, largely surrounded by land. Countries that have a major influence on and claims to the sea include China, Malaysia, the Philippines and Vietnam, although Thailand, Indonesia and Taiwan have some too. The coastal fringes of the South China Sea are home to about 270 million people that have had some of the fastest developing and most vibrant economies on the globe. Consequently, anthropogenic impacts, such as over-exploitation of resources and pollution, are anticipated to be huge although, in reality, relatively little is known about them. The Indo-West Pacific biogeographic province, at the centre of which the South China Sea lies, is probably the world's most diverse shallow-water marine area.

    Full Text Available In Germany, with the exception of the five federal supreme courts, court organization is a responsibility of the Länder (federal states. In some of the Länder, so-called employee profiles (“Anforderungsprofile“ have been established for judicial office. These lists attempt to describe criteria for certain judicial positions. They are applied in the process of promotion but also serve as an indicator for initial appointment.The European picture with respect to individual evaluation of judges is extremely diverse. In preparation for this paper, the author attempted to ascertain the situation in the Council of Europe member states. The results of this survey (to which 23 members of the CCJE have replied are listed in Appendix I.The general difficulty of professional evaluation of judges lies in the limits that have to be observed for constitutional reasons. In Germany, the overall rule of every evaluation is that there has to be a reliable factual basis. The evaluator is under a duty not to omit relevant aspects, to consider all the facts that make part of the picture, not to select arbitrarily but to try to paint a true and full picture of the person who is being evaluated. In the case of judges, it is unacceptable to comment on the core of judicial decision-making. Evaluations may be challenged in the administrative court on grounds of fact as well as on grounds of law.

    The transport of radioactive waste is centralised and coordinated by the German Railway Company (Deutsche Bahn AG, DB) in Germany. The conditioning of radioactive waste is now centralised and carried out by the Gesellschaft fuer Nucklear Service (GNS). The Germany Railway Company, DB, is totally and exclusively responsible for the transport, the GNS is totally and exclusively responsible for the conditioning of radioactive waste. The German Railway Company transports all radioactive waste from nuclear power plants, conditioning facilities and the existing intermediate storage facilities in Germany. In 1992 nearly 177 shipments of radioactive waste were carried out, in 1991 the total amount was 179 shipments. A brief description of the transport procedures, the use of different waste packages for radioactive waste with negligible heat generation and the transport routes within Germany will be given. For this purpose the inspection authorities in Germany have used a new documentation system, a special computer program for waste flow tracking and quality assurance and compliance assurance, developed by the electrical power companies in Germany.

    With the amendment of the German Medicinal Products Act in 1976 and the inclusion of naturopathy and homeopathy into the German Medical Licensure Act from 1988, the German government set up a comparatively favorable framework for Complementary and Alternative Medicine (CAM). But no comprehensive integration into the academic operating systems followed, because the universities as well as the legislative body seemed to have no further interest in CAM. Therefore, research projects in the field and suitable professorships had and still have to be financed by third-party funds. Notwithstanding the success of several CAM-projects, no sustainable development could be established: When the third-party funding runs off and the protagonists retire the institutional structures are supposed to vanish as well. Although the public demand for CAM is high in Germany, the administration detached homeopathy as a compulsory subject from the German Medical Licensure Act in 2002 and restricted severely the refunding of naturopathic medicines by the statutory health insurance in 2004. Moreover, the trend for CAM bashing takes root in the media. Unfortunately the CAM scene does not close ranks and is incapable to implement fundamental data collection processes into daily clinical routine: A wide range of data could justify further efforts to the government as well as to the scientific community. To say something positive, it must be mentioned that the scientific standard of CAM research is high for the most part and that third-party funded projects deliver remarkable results ever and on.

    One of the reasons for young doctors to leave the clinical work to go abroad or into non-clinical fields is insufficient quality of training under bad circumstances. Aim of the study was to evaluate the surgical training in Germany from the viewpoint of the residents. A questionnaire was prepared by residents and consultants and approved by the German surgical societies (Deutsche Gesellschaft fur Chirurgie und Berufsverband der Deutschen Chirurgen). It was sent to surgical residents between June 2003 and June 2004, published in "Der Chirurg BDC" and distributed among residents taking part in courses conducted by the BDC. It could be answered anonymously by email, mail or online. The questionnaire was sent back by 584 surgical residents (about 30 % of all). 58 % of the residents declared that they finished the training in the intended time (6 years). Rotation-systems as part of a structured residency program existed for 43 %. Standard surgical procedures were discussed or explained before the procedure in only 46 %. 61 % of the residents were not satisfied with the teaching assistance by their clinical teachers in the OR. Only 33 % had regular talks with the Chief about their progress in surgical training. 18 % of residents felt, that the hospital is interested in their progress in training. Indication-conferences took place in 52 % and mortality-conferences in only 20 % of programs. Regular seminars on recent issues took place in 62 %, and 61 % of residents did not get financial support to attend congresses. 36 % of residents had to use their holidays to attend congresses. Surgical training structures are not well established in about 50 % of the training hospitals from where we got answers to our survey. The training potential of daily surgical work is not used appropriately. It is therefore imperative to develop guidelines for surgical training, the use of log-books and rotation-programs.

  11. The use of IMRT in Germany

    2015-01-01

    Intensity modulated radiotherapy (IMRT) is frequently used, but there are no data about current frequency regarding specific tumor sites and equipment used for quality assurance (QA). An online survey about IMRT was executed from April to October 2014 by the collaborative IMRT working group (AK IMRT) of the German Association of Medical Physicists (DGMP). A total of 23 German institutions took part in the survey. Most reports came from users working with Elekta, Varian, and Siemens treatment machines, but also from TomoTherapy and BrainLab. Most frequent IMRT technology was volumetric modulated arc therapy (58.37 %: VMAT/''rapid arc''), followed by step-and-shoot IMRT (14.66 %), dynamic MLC (dMLC: 14.53 %), TomoTherapy (9.25 %), and 3.2 % other techniques. Different commercial hard- and software solutions are available for QA, whereas many institutes still develop their own phantoms. Data of 26,779 patients were included in the survey; 44 % were treated using IMRT techniques. IMRT was most frequently used for anal cancer, (whole) craniospinal irradiation, head and neck cancer, prostate cancer, other tumors in the pelvic region, gynecological tumors (except for breast cancer), and brain tumors. An estimated 10 % of all patients treated in 2014 with radiation in Germany were included in the survey. It is representative for the members of the AK IMRT. IMRT may be on the way to replace other treatment techniques. However, many scientific questions are still open. In particular, it is unclear when the IMRT technique should not be used. (orig.) [de

    2001-01-01

    The question of the future of nuclear power in Germany, and the agreement between the federal government and industry of June 14, 2000 about the future operation of plants, are important far beyond the confines of this sector of industry. In times of economic globalization and of competition among national economies, questions of location have become key issues in meeting future challenges. For this purpose, there must be more freedom for the economy; entrepreneurial action must be regarded as a positive duty to be fulfilled by society. Personal responsibility and competition, with room for self-responsibility, must not be hampered further by interventions and red tape. This applies to all sectors of the economy, in particular to the power supply sector, as is borne out by the current debate about the quota regulations for cogeneration systems (CHP). Social justice, one of the most important unifying forces in this modern society, must be interpreted as solidarity. This solidarity must be sought also in an international context. Supplying the basic necessities to all inhabitants of this earth requires all sources of energy, also in the interest of achieving sustainability. This term should be interpreted, above and beyond its meaning in environmental protection, as a concept in all areas of politics, implying that the future must be taken into account in all decisions made today. In the light of the problems associated with establishing a worldwide sustainable power supply system, inter alia meeting the objectives of climate protection, continuity of supply, and economic viability, there is no way around nuclear power. Free decisions are required in the sense of sustainable economic management, and the political boundary conditions must be created for this to be possible. (orig.) [de

    Within the scope of limited nonrenewable energy resources and the limited capacity of the ecosystem for greenhouse gases and nuclear waste, sustainability is one important target in the future. Different energy scenarios showed the huge potential for photovoltaics (PV) to solve this energy problem. Nevertheless, in the last decade, PV had an average growth rate of over 20% per year. In 2002, the solar industry delivered more than 500 MWp/year of photovoltaic generators [A. Jaeger-Waldau, A European Roadmap for PV R and D, E-MRS Spring Meeting, (2003)]. More than 85% of the current production involves crystalline silicon technologies. These technologies still have a high cost reduction potential, but this will be limited by the silicon feedstock. On the other hand the so-called second generation thin film solar cells based on a-Si, Cu(In,Ga)(Se,S 2 (CIGS) or CdTe have material thicknesses of a few microns as a result of their direct band gap. Also, the possibility of circuit integration offers an additional cost reduction potential. Especially in Germany, there are a few companies who focus on thin film solar cells. Today, there are two manufacturers with production lines: the Phototronics (PST) division of RWE-Schott Solar with a-Si thin film technology and the former Antec Solar GmbH (now Antec Solar Energy GmbH) featuring the CdTe technology. A pilot line based on CIGS technology is run by Wuerth Solar GmbH. There is also a variety of research activity at other companies, namely, at Shell Solar, Sulfurcell Solartechnik GmbH, Solarion GmbH and the CIS-Solartechnik GmbH. We will give an overview on research activity on various thin film technologies, as well as different manufacturing and production processes in the companies mentioned above. (Author)

    Measuring sea level change and understanding its causes has considerably improved in the recent years, essentially because new in situ and remote sensing observations have become available. Here we report on most recent results on contemporary sea level rise. We first present sea level observations from tide gauges over the twentieth century and from satellite altimetry since the early 1990s. We next discuss the most recent progress made in quantifying the processes causing sea level change on timescales ranging from years to decades, i.e., thermal expansion of the oceans, land ice mass loss, and land water-storage change. We show that for the 1993-2007 time span, the sum of climate-related contributions (2.85 +/- 0.35 mm year(-1)) is only slightly less than altimetry-based sea level rise (3.3 +/- 0.4 mm year(-1)): approximately 30% of the observed rate of rise is due to ocean thermal expansion and approximately 55% results from land ice melt. Recent acceleration in glacier melting and ice mass loss from the ice sheets increases the latter contribution up to 80% for the past five years. We also review the main causes of regional variability in sea level trends: The dominant contribution results from nonuniform changes in ocean thermal expansion.

    California’s coastal observations and global model projections indicate that California’s open coast and estuaries will experience increasing sea levels over the next century. Sea level rise has affected much of the coast of California, including the Southern California coast, the Central California open coast, and the San Francisco Bay and upper estuary. These trends, quantified from a small set of California tide gages, have ranged from 10–20 centimeters (cm) (3.9–7.9 inches) per century, quite similar to that estimated for global mean sea level. So far, there is little evidence that the rate of rise has accelerated, and the rate of rise at California tide gages has actually flattened since 1980, but projections suggest substantial sea level rise may occur over the next century. Climate change simulations project a substantial rate of global sea level rise over the next century due to thermal expansion as the oceans warm and runoff from melting land-based snow and ice accelerates. Sea level rise projected from the models increases with the amount of warming. Relative to sea levels in 2000, by the 2070–2099 period, sea level rise projections range from 11–54 cm (4.3–21 in) for simulations following the lower (B1) greenhouse gas (GHG) emissions scenario, from 14–61 cm (5.5–24 in) for the middle-upper (A2) emission scenario, and from 17–72 cm (6.7–28 in) for the highest (A1fi) scenario. In addition to relatively steady secular trends, sea levels along the California coast undergo shorter period variability above or below predicted tide levels and changes associated with long-term trends. These variations are caused by weather events and by seasonal to decadal climate fluctuations over the Pacific Ocean that in turn affect the Pacific coast. Highest coastal sea levels have occurred when winter storms and Pacific climate disturbances, such as El Niño, have coincided with high astronomical tides. This study considers a range of projected future

    Editor's Note: The caption below, published on May 10, 2001, is incorrect. According to Masha Vorontsova, director of the International Fund for Animal Welfare in Moscow, the situation with the seal pups in the White Sea is normal. There is no disaster and there never was. For more details, refer to the article entitled 'No Danger' on the New Scientist home page. The Earth Observatory regrets the earlier errant report. Original Caption According to the Russian Polar Research Institute for Fisheries and Oceanography, between 250,000 and 300,000 Greenland seal pups face death by starvation over the next two months due to a cruel trick by mother nature. The seals, most of them less than two months old, are trapped on ice sheets that remain locked in the White Sea, located near Archangel in Northern Russia. Typically, during the spring thaw the ice sheets break up and flow with the currents northward into the Barents Sea, the seals' spring feeding grounds. The seal pups hitch a ride on the ice floes, living on their own individual stores of fat until they arrive in the Barents Sea. Their mothers departed for the Barents Sea weeks ago. In a normal year, the seal pups' trip from the White Sea out to the Barents takes about six weeks and the seals have adapted to rely upon this mechanism of mother nature. During their yearly migration, the mother seals usually stay with their pups and feed them until their pelts turn from white to grey--a sign that the pups are mature enough to swim and feed themselves. Unfortunately, this year unusually strong northerly winds created a bottleneck of ice near the mouth of the white sea, thus blocking the flow of ice and trapping the pups. These true-color images of the White Sea were acquired by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra spacecraft. This image, taken May 2, 2000 that there is usually much less ice in the White Sea this time of year as most of it is typically en route to the

    Full Text Available Sea buckthorn leaves and branches presently create waste-/by-products of harvesting after pruning the plants. It is already known that sea buckthorn berries are important for their chemical composition and based on this occupy a wide field in nutrition. We raised the idea that sea buckthorn leaves, branches, and especially the bark, have also an extraordinary chemical composition like the berries. The aim of this study was to describe these by-products. For this purpose, detailed full analyses of corresponding samples from Russia (seven varieties and Germany (four varieties were performed. Especially the dry mass, fat content, proteins, carbohydrates, starch content, and crude fiber were investigated to obtain an overview. Minor components like total phenol content, metals, and water- and fat-soluble vitamins were also studied. All analytical parameters were based on an official collection of analysis methods (German ASU - amtliche Sammlung von Untersuchungsverfahren. The results of the full analysis of leaves and branches show some interesting aspects about the differences between male and female plants. Furthermore, we observed differences between Russian and German sea buckthorn varieties. Investigation of minor components showed that vitamins were present in very low amount (< 0.1 %.

    On 6th April 1945, nine days before the liberation of the Bergen Belsen Concentration Camp, about 2,500 Jewish prisoners were ordered to prepare to leave the camp on the next day. On 7th April, the prisoners left through the gates of the camp and began to walk about 10 kilometers to the train station near the city of Celle. There they were ordered to board a train that would take them to the Theresienstadt Concentration Camp. After six days of travel, the train stopped near the village of Farsleben, Germany, where it was liberated by the 743rd Tank Battalion of the 30th Infantry Division, of the U.S. 9th Army, on 13th April 1945. The 105th Medical Battalion of the same Division was the primary care provider for the survivors, who were then taken in vehicles available from the 30th Infantry Division, and organized into a convoy by the Division's Liaison Officer, Lt. Frank W. Towers, to the town of Hillersleben. A former German Air Force Base was located at Hillersleben with a small hospital that could not provide medical attention to all the survivors. On 21st April, Company C of the 95th Medical Battalion, received an order to go to Hillersleben. Colonel Dr. William W. Hurteau, the Commanding Officer of this Battalion, determined that the biggest task given to the Battalion during World War II, was establishing another hospital in the town of Hillersleben and providing additional beds in the existing hospital, which was a structure that had served as a boarding school. Furthermore, they needed to acquire hospital equipment which was obtained from German equipment and supplies that had been captured by the U.S. MiLitary. Also, they took care of obtaining food supplies from German warehouses, and meat and milk from local dairy farms. The lives of the prisoners on this train were saved by the heroism and dedicated work of those brave soldiers of the 30th Infantry Division and the 95th Medical Battalion.

    The Dead Sea is the lowest point on Earth at 418 meters below sea level, and also one of the saltiest bodies of water on Earth with a salinity of about 300 parts-per-thousand (nine times greater than ocean salinity). It is located on the border between Jordan and Israel, and is fed by the Jordan River. The Dead Sea is located in the Dead Sea Rift, formed as a result of the Arabian tectonic plate moving northward away from the African Plate. The mineral content of the Dead Sea is significantly different from that of ocean water, consisting of approximately 53% magnesium chloride, 37% potassium chloride and 8% sodium chloride. In the early part of the 20th century, the Dead Sea began to attract interest from chemists who deduced that the Sea was a natural deposit of potash and bromine. From the Dead Sea brine, Israel and Jordan produce 3.8 million tons potash, 200,000 tons elemental bromine, 45,000 tons caustic soda, 25, 000 tons magnesium metal, and sodium chloride. Both countries use extensive salt evaporation pans that have essentially diked the entire southern end of the Dead Sea. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining

    As a comparative overview of the French and German situation regarding electric power, a first article proposes tables and graphs illustrating data evolution, and brief comments about these evolutions. Comparison focuses on household electricity consumption, on electricity exchanges, and on the production of electricity based on renewable energies. An appendix proposes a presentation of the German policy for energy transition: principles and objectives, phasing out nuclear, implementation. Then, an article, illustrated by data tables and graphs, discusses the evolution of electric power production and consumption in Germany between 2000 and 2013. The author addresses power final consumption, power total production and exchanges, the components of electric power production, and greenhouse gas emissions (by fossil fuel, by sector, and by electricity and heat production)

    The French-German office for Renewable energies (OFAEnR) organised a conference on participatory wind energy in France and in Germany. In the framework of this French-German exchange of experience, about 150 participants exchanged views on the role and involvement of citizens in wind energy projects and raised the question of the prerequisite to the construction of a participatory wind farm. In this framework, the different participatory models existing in both countries were analysed, in particular with regard to their respective advantages and drawbacks and to a legal framework which remains to be defined. Four projects, 2 in France and 2 in Germany, were presented as examples. The call for proposals model was presented and debated as well as the question of the project success, and of its financing and profitability. This document brings together the available presentations (slides) made during this event: 1 - Community wind farms in Germany: status quo and forecast (Philipp Vohrer); 2 - Participatory projects in France: which legal solutions, which prospects for development?

    2012-07-01

    Germany has very little domestic oil and natural gas production and relies heavily on imports. It has well diversified and flexible oil and natural gas supply infrastructure, which consists of crude, product and gas pipelines and crude and oil product import terminals. Natural gas is imported into Germany exclusively by cross-border pipeline. The country has no LNG infrastructure, although some German companies have booked capacities in overseas LNG terminals. Oil continues to be the main source of energy in Germany although it has declined markedly since the early 1970s. It now represents approximately 32% of Germany’s total primary energy supply (TPES). Natural gas consumption in Germany has declined 10% since 2006. Demand was 90 bcm in 2010, down from 100 bcm in 2005. According to government commissioned analysis, the total consumption of natural gas in Germany is expected to continue to decline over the long term. The share of natural gas in Germany’s TPES is currently around 22%. German oil stock levels are generally well above the required 90-days. Total oil stock levels in Germany were equivalent to 140 days net imports in April 2012. Since 1998, the German oil stockholding agency (EBV) has been solely responsible for meeting Germany's 90-day stockholding obligation. The Oil Stockholding Act stipulates that the EBV shall constantly maintain stocks of oil and petroleum products at a level equivalent to or above 90 days of net imports. There is no minimum stockholding obligation on industry, so industry held commercial stocks are held in addition to the EBV stocks. There are several legal tools available to German authorities for natural gas emergency response. These include Ordinances that can be used to restrict the sale, purchase or use of goods, both in terms of quantity and time, or permit them only for certain priority purposes, to ensure that vital energy needs are met. There are no compulsory natural gas storage requirements in Germany, and no

    Secure, sufficient electricity supplies available at any time, as guaranteed in Germany, are vital to the existence of our modern society. Under the conditions of deregulated markets, it must continue to be possible in Germany to offer reliable, economical and non-polluting energy supplies. These three factors should enjoy equal importance in energy policy decisions in the interest of sustainability. The skewed balance caused by political preferences as experienced at the present time can jeopardize the general objective of optimization of the three factors in the long run. As in no other country, the power industry in Germany had to make a considerable adaptation effort, inter alia, because of market deregulation, airborne pollutant reduction, and agreements on the operating life of existing nuclear power plants. Other problems are likely to arise in the near future, e.g. in connection with emission trading. The power industry is willing and able to solve these future problems. This is true in particular of the expected replacement of power plants of approx. 40 000 MW generating capacity in Germany, where the European framework must be taken into account with a replacement requirement of approx. 200 000 MW. This implies investments of euro 50 billion in Germany alone, which can be made only if there is sufficient security in planning for the operators of power plants. The choice of efficient and economically viable power generation technologies must be possible in this respect. (orig.) [de

    Full Text Available Replenishment at sea is a process which plays the key role in the contemporary naval logistics during military and crisis operations. As the last element of the supply chain, it must use specific standards within the areas of procedures, technical equipment, logistic assets and resources, as well as safety, especially in multinational operations. The methods applied enable ships to operate at sea in the long term without logistic support provided by sea ports. The paper explains all the methods of the solids and liquids replenishment, and also gives an idea how to estimate the resupply process, using the measures. The level of standardization of procedures and assets implemented by NATO, the EU and other willing states has been described.

Air-Sea Interaction: Laws and Mechanisms is a comprehensive account of how the atmosphere and the ocean interact to control the global climate, what physical laws govern this interaction, and its prominent mechanisms. The topics covered range from evaporation in the oceans, to hurricanes, and on to poleward heat transport by the oceans. By developing the subject from basic physical (thermodynamic) principles, the book is accessible to graduate students and research scientists in meteorology, oceanography, and environmental engineering. It will also be of interest to the broader physics community involved in the treatment of transfer laws, and thermodynamics of the atmosphere and ocean.

    Over the past 500 years almost 100 tsunamis have been observed in the Caribbean and Western Atlantic, with at least 3510 people having lost their lives to this hazard since 1842. Furthermore, with the dramatic increase in population and infrastructure along the Caribbean coasts, today, millions of coastal residents, workers and visitors are vulnerable to tsunamis. The UNESCO IOC Intergovernmental Coordination Group for Tsunamis and other Coastal Hazards for the Caribbean and Adjacent Regions (CARIBE EWS) was established in 2005 to coordinate and advance the regional tsunami warning system. The CARIBE EWS focuses on four areas/working groups: (1) Monitoring and Warning, (2) Hazard and Risk Assessment, (3) Communication and (4) Education, Preparedness and Readiness. The sea level monitoring component is under Working Group 1. Although in the current system, it's the seismic data and information that generate the initial tsunami bulletins, it is the data from deep ocean buoys (DARTS) and the coastal sea level gauges that are critical for the actual detection and forecasting of tsunamis impact. Despite multiple efforts and investments in the installation of sea level stations in the region, in 2004 there were only a handful of sea level stations operational in the region (Puerto Rico, US Virgin Islands, Bermuda, Bahamas). Over the past 5 years there has been a steady increase in the number of stations operating in the Caribbean region. As of mid 2012 there were 7 DARTS and 37 coastal gauges with additional ones being installed or funded. In order to reach the goal of 100 operational coastal sea level stations in the Caribbean, the CARIBE EWS recognizes also the importance of maintaining the current stations. For this, a trained workforce in the region for the installation, operation and data analysis and quality control is considered to be critical. Since 2008, three training courses have been offered to the sea level station operators and data analysts. Other

    The most significant source of anthropogenic radioactivity in the Baltic Sea is fallout from the accident at the Chernobyl nuclear power plant in 1986. The second most important source is global fallout from atmospheric nuclear weapons tests carried out during the late 1950s and early 1960s...... about 14%. For 90Sr in the Baltic Sea, input from atmospheric fallout from nuclear weapons tests has contributed about 81%, while the contribution from Chernobyl fallout was about 13%. Cesium-137 is the main indicator of Baltic seawater with respect to anthropogenic radioactivity. The highest...... concentrations in seawater during 1999–2006 were found in the Baltic Proper and the Bothnian Sea. The general trend is steadily decreasing. Concentrations of anthropogenic radioactivity in fish generally show decreasing trends in agreement with concentrations in seawater. Among freshwater fish, pike showed large...

    Climate change challenges science, politics, business and society at the international, national and regional level. The South German Climate Office at the Karlsruhe Institute of Technology (KIT) is a contact for the structuring and dissemination of information on climate and climate change in the South German region. It provides scientifically based and user-oriented climate information. Thereby it builds a bridge between the climate sciences and society and provides scientific information on climate change in an understandable way. The expertise of KIT, in which several institutions operate on fundamental and applied climate research, and of partner institutions is the basis for the work in the climate office. The regional focus is on the south of Germany. Thematic focuses are e.g. regional climate modeling, trends in extreme weather events such as heavy rain and hail event, and issues for energy and water management. The South German Climate Office is one of four Regional Helmholtz Climate Offices, of which each has a regional and thematic focus. The users of the Climate Office can be summarized into three categories. First, there is the general public. This category consists mainly of non-professionals. Here, special attention is on an understandable translation of climate information. Attention is paid to application-related aspects, because each individual is affected in a different way by climate change. Typical examples of this category are school groups, citizens and the media. The second category consists of experts of other disciplines. Unlike the first category they are mainly interested in the exchange of results and data. It is important to the climate office to provide support for the use of climatological results. Typical representatives of this category are ministries, state offices, and companies. In the third and final category are scientists. In addition to the climatologists, this category also holds representatives from other scientific

    The North Sea can be considered as a local 'inner' sea in which many processes are quite different from these over the open ocean. The surrounding land has a major influence, being the source for man-made aerosols and gases, whereas the North Sea acts as a sink for these. At the same time the North

    After several decades of economic growth with a continuous increase of energy consumptions, a new trend is now developing in Germany: reduction of energy consumptions and of pollutant emissions. This paper analyzes first the energy supplies of Germany (consumption, sources), the consumption by sector, and the share of the different energy sources in the German consumption (petroleum, coal, natural gas, nuclear power, and renewable energies). In a second part, the German energy policy is presented with its priorities and actions regarding the environment protection: energy savings, development of renewable energy sources, reduction of automotive fuels consumption, rational use of energy, thermal insulation of buildings, financial incentives etc.. Finally, the forecasting of future energy consumption and pollutants emission trends in Germany and at the worldwide scale are evoked. (J.S.)

    The framework within which the research studies on high temperature reactors have been pursued in West Germany since 1960 is recalled. The principles guiding the present policy of the country in this domain are given: choice of a single technical conception that be applied both to reactors generating electricity and reactors producing high temperature heat for industrial processes such as coal gasification; to group the technical and industrial potentials of West Germany in this domain; financial and technical participation of electricity producers in the expected realizations; international cooperation. In this technique, West Germany is at present among the most advanced nations with the realization of a prototype 300 MWe reactor, financed by the electricity producers and a contribution of government [fr

    Opinion polls show that photovoltaic power is very popular in Germany. This sector employs about 130.000 people and although a lot of solar modules are imported from China, other components like current inverters are fabricated in Germany and as a whole the trade balance is positive and the export rate nears 50%. In 2011 Germany invested 25 billion euros in the photovoltaic sector and now about 5% of the consumed electricity is photovoltaic power. Photovoltaic power reached grid parity in february 2012 for some consumers and the German government decided to reduce the purchase tariff drastically which may jeopardize the aim of having a photovoltaic park of 51 GWc by 2020.
