    The Provisional Technical Secretariat (PTS) of the Comprehensive Nuclear-Test-Ban Treaty (CTBTO) has a continuous interest in enhancing its capability in acoustic source detection, localization and characterization. The infrasound component of the International Monitoring System (IMS) constitutes the only worldwide ground-based infrasound network. It consists of sixty stations, among which forty-eight are already certified and continuously transmit data to the International Data Centre (IDC) in Vienna, Austria. Each infrasound station is composed of an array of infrasound sensors capable of measuring micro-pressure changes produced at ground level by infrasonic waves. The characteristics of infrasonic waves are computed in near real-time by IDC automatic detection software and are used as an input to IDC source categorization and localization algorithms. The PTS is continuously working towards the completion and sustainment of the IMS infrasound network. The objective of this presentation is to review the main activities performed in the IMS infrasound network over the last five years. This includes construction, installation, certification, major upgrade and revalidation activities. Major technology development projects to improve the reliability and robustness of IMS infrasound stations as well as their compliance with IMS Operational Manual requirements will also be presented. This includes advances in array geometry, wind noise reduction, system calibration, meteorological data as well as power and communication infrastructures. Finally the impact of all these changes on the overall detection capability of the IMS infrasound network will be highlighted.

  5. Uncertainties in sea level projections on twenty-year timescales

    2016-04-01

    Regional decadal changes in sea level are governed by various processes, including ocean dynamics, gravitational and solid earth responses, mass loss of continental ice, and other local coastal processes. In order to improve predictions and physical attribution in decadal sea level trends, the uncertainties of each processes must be reflected in the sea level calculations. Here we explore uncertainties in predictions of the decadal and bi-decadal changes in regional sea level induced by the changes in ocean dynamics and associated redistribution of heat and freshwater (often referred to as dynamic sea level). Such predictions are typically based on the solutions from coupled atmospheric and oceanic general circulation models, including a suite of climate models participating in phase 5 of the Coupled Model Intercompasion Project (CMIP5). Designed to simulate long-term ocean variability in response to warming climate due to increasing green-house gas concentration ("forced" response), CMIP5 are deficient in simulating variability at shorter time scales. In contrast, global observations of sea level are available during a relatively short time span (e.g., twenty-year altimetry records), and are dominated by an "unforced" variability that occurs freely (internally) within the climate system. This makes it challenging to examine how well observations compare with model simulations. Therefore, here we focus on patterns and spatial characteristics of projected twenty-year trends in dynamic sea level. Based on the ensemble of CMIP5 models, each comprising a 240-year run, we compute an envelope of twenty-year rates, and analyze the spread and spatial relationship among predicted rates. An ensemble root-mean-square average exhibits large-scale spatial patterns, with the largest uncertainties found over mid and high latitudes that could be attributed to the changes in wind patterns and buoyancy forcing. To understand and parameterize spatial characteristics of the

    Drought is occurring with increased frequency under climate warming. To understand the behavior of drought and its variation in the future, current and future drought in the twenty-first century over China is discussed. The drought frequency and trend of drought intensity are assessed using the Palmer Drought Severity Index (PDSI), which is calculated based on historical meteorological observations and outputs of the fifth Coupled Model Intercomparison Project (CMIP5) under three representative concentration pathway (RCP) scenarios. The simulation results of drought period, defined by PDSI class, could capture more than 90% of historical drought events. Projection results indicate that drought frequency will increase over China in the twenty-first century under the RCP4.5 and RCP8.5 scenarios. In the mid-twenty-first century (2021-2050), similar patterns of drought frequency are found under the three emission scenarios, and annual drought duration would last 3.5-4 months. At the end of the twenty-first century (2071-2100), annual drought duration could exceed 5 months in northwestern China as well as coastal areas of eastern and southern China under the RCP8.5 scenario. Drought is slightly reduced over the entire twenty-first century under the RCP2.6 scenario, whereas drought hazards will be more serious in most regions of China under the RCP8.5 scenario.

    2013-01-01

    This paper reconciles the difference in the projections of the wet season over the Southeastern United States (SEUS) from a global climate model (the Community Climate System Model Version 3 [CCSM3]) and from a regional climate model (the Regional Spectral Model [RSM]) nested in the CCSM3. The CCSM3 projects a dipole in the summer precipitation anomaly: peninsular Florida dries in the future climate, and the remainder of the SEUS region becomes wetter. The RSM forced with CCSM3 projects a universal drying of the SEUS in the late twenty-first century relative to the corresponding twentieth-century summer. The CCSM3 pattern is attributed to the “upped-ante” mechanism, whereby the atmospheric boundary layer moisture required for convection increases in a warm, statically stable global tropical environment. This criterion becomes harder to meet along convective margins, which include peninsular Florida, resulting in its drying. CCSM3 also projects a southwestward expansion of the North Atlantic subtropical high that leads to further stabilizing of the atmosphere above Florida, inhibiting convection. The RSM, because of its high (10-km grid) resolution, simulates diurnal variations in summer rainfall over SEUS reasonably well. The RSM improves upon CCSM3 through the RSM’s depiction of the diurnal variance of precipitation, which according to observations accounts for up to 40 % of total seasonal precipitation variance. In the future climate, the RSM projects a significant reduction in the diurnal variability of convection. The reduction is attributed to large-scale stabilization of the atmosphere in the CCSM3 projections.

    Retreat of mountain glaciers is a significant contributor to sea-level rise and a potential threat to human populations through impacts on water availability and regional hydrology. Like most of Earth’s mountain glaciers, those in western North America are experiencing rapid mass loss. Projections of future large-scale mass change are based on surface mass balance models that are open to criticism, because they ignore or greatly simplify glacier physics. Here we use a high-resolution regional glaciation model, developed by coupling physics-based ice dynamics with a surface mass balance model, to project the fate of glaciers in western Canada. We use twenty-first-century climate scenarios from an ensemble of global climate models in our simulations; the results indicate that by 2100, the volume of glacier ice in western Canada will shrink by 70 +/- 10% relative to 2005. According to our simulations, few glaciers will remain in the Interior and Rockies regions, but maritime glaciers, in particular those in northwestern British Columbia, will survive in a diminished state. We project the maximum rate of ice volume loss, corresponding to peak input of deglacial meltwater to streams and rivers, to occur around 2020-2040. Potential implications include impacts on aquatic ecosystems, agriculture, forestry, alpine tourism and water quality.

    Sea-level rise is one of the most pressing aspects of anthropogenic global warming with far-reaching consequences for coastal societies. However, sea-level rise did and will strongly vary from coast to coast. Here we investigate the long-term internal variability effects on centennial projections of dynamic sea level (DSL), the local departure from the globally averaged sea level. A large ensemble of global warming integrations has been conducted with a climate model, where each realization was forced by identical CO2 increase but started from different atmospheric and oceanic initial conditions. In large parts of the mid- and high latitudes, the ensemble spread of the projected centennial DSL trends is of the same order of magnitude as the globally averaged steric sea-level rise, suggesting that internal variability cannot be ignored when assessing twenty-first-century DSL trends. The ensemble spread is considerably reduced in the mid- to high latitudes when only the atmospheric initial conditions differ while keeping the oceanic initial state identical; indicating that centennial DSL projections are strongly dependent on ocean initial conditions.

    Europe faces a great challenge with the 2020 scenario in which the renewable energy installed capacity in Europe should increase from its present value of approximately 80 GW to 230 GW in 2020. The future high penetration levels of wind and other renewable energies in the power system require decision makers and stakeholders of the electrical sector to work together to develop new ancillary services and to make the necessary changes to the grid infrastructure in Europe. This background is in line with the SYSERWIND demonstration lead by Iberdrola Renovables and included in the TWENTIES project, with three more partners taking part in this package: Red Electrica de Espana (REE), IIT and Gamesa Eolica. This paper introduces a first phase of preliminary work to define, install and test a Secondary Frequency Control and a Voltage Management System in a wide area, along a transport line. (orig.)

    We project glacier surface mass balances of the Altai Mountains over the period 2006-2100 for the representative concentration pathway (RCP) 4.5 and RCP8.5 scenarios using daily near-surface air temperature and precipitation from 12 global climate models in combination with a surface mass balance model. The results indicate that the Altai glaciers will undergo sustained mass loss throughout the 21st for both RCPs and reveal the future fate of glaciers of different sizes. By 2100, glacier area in the region will shrink by 26 ± 10 % for RCP4.5, while it will shrink by 60 ± 15 % for RCP8.5. According to our simulations, most disappearing glaciers are located in the western part of the Altai Mountains. For RCP4.5, all glaciers disappearing in the twenty-first century have a present-day size smaller than 5.0 km2, while for RCP8.5, an additional 7 % of glaciers in the initial size class of 5.0-10.0 km2 also vanish. We project different trends in the total meltwater discharge of the region for the two RCPs, which does not peak before 2100, with important consequences for regional water availability, particular for the semi-arid and arid regions. This further highlights the potential implications of change in the Altai glaciers on regional hydrology and environment.

    In this study, we present the projected seasonal mean summer monsoon over India and adjoining regions for the twenty-first century under the representative concentration pathway (RCP) 4.5 and RCP 8.5 scenarios using the regional model RegCM4 driven by the global model GFDL-ESM2M. RegCM4 is integrated from 1970 to 2099 at 50 km horizontal resolution over the South Asia CORDEX domain. The simulated mean summer monsoon circulation and associated rainfall by RegCM4 are validated against observations in the reference period 1975 to 2004 based on the Global Precipitation Climatology Project (GPCP) and India Meteorological Department (IMD) data sets. Regional model results are also compared with those of the global model GFDL which forces the RegCM4, showing that the regional model in particular improves the simulation of precipitation trends during the reference period. Future projections are categorized as near future (2010-2039), mid future (2040-2069), and far future (2070-2099). Comparison of projected seasonal (June-September) mean rainfall from the different time slices indicate a gradual increase in the intensity of changes over some of the regions under both the RCP4.5 and RCP8.5 scenarios. RegCM4 projected rainfall decreases over most of the Indian land mass and the equatorial and northern Indian Ocean, while it increases over the Arabian Sea, northern Bay of Bengal, and the Himalayas. Results show that the monsoon circulation may become weaker in the future associated with a decrease in rainfall over Indian land points. The RegCM4 projected decrease in June, July, August, September (JJAS) rainfall under the RCP8.5 scenario over the central, eastern, and peninsular India by the end of the century is in the range of 25-40 % of their mean reference period values; it is significant at the 95 % confidence level and it is broadly in line with patterns of observed change in recent decades. Surface evaporation is projected to increase over the Indian Ocean, thereby

    In this study, probabilistic projections of precipitation for the Province of Ontario are developed through a regional climate model ensemble to help investigate how global warming would affect its local climate. The PRECIS regional climate modeling system is employed to perform ensemble simulations, driven by a set of boundary conditions from a HadCM3-based perturbed-physics ensemble. The PRECIS ensemble simulations are fed into a Bayesian hierarchical model to quantify uncertain factors affecting the resulting projections of precipitation and thus generate probabilistic precipitation changes at grid point scales. Following that, reliable precipitation projections throughout the twenty-first century are developed for the entire province by applying the probabilistic changes to the observed precipitation. The results show that the vast majority of cities in Ontario are likely to suffer positive changes in annual precipitation in 2030, 2050, and 2080 s in comparison to the baseline observations. This may suggest that the whole province is likely to gain more precipitation throughout the twenty-first century in response to global warming. The analyses on the projections of seasonal precipitation further demonstrate that the entire province is likely to receive more precipitation in winter, spring, and autumn throughout this century while summer precipitation is only likely to increase slightly in 2030 s and would decrease gradually afterwards. However, because the magnitude of projected decrease in summer precipitation is relatively small in comparison with the anticipated increases in other three seasons, the annual precipitation over Ontario is likely to suffer a progressive increase throughout the twenty-first century (by 7.0 % in 2030 s, 9.5 % in 2050 s, and 12.6 % in 2080 s). Besides, the degree of uncertainty for precipitation projections is analyzed. The results suggest that future changes in spring precipitation show higher degree of uncertainty than other

    Two dynamical methods are presently used to project sea-level changes during the next century. The process-based method relies on coupled atmosphere-ocean models to estimate the effects of thermal expansion and on sea-level models combined with certain empirical relationships to determine the influence of land-ice mass changes. The semi-empirical method uses various physically motivated relationships between temperature and sea level, with parameters determined from the data, to project total sea level. However, semi-empirical projections far exceed process-based projections. Here, we test the robustness of semi-empirical projections to the underlying assumptions about the inertial and equilibrium responses of sea level to temperature forcing and the impacts of groundwater depletion and dam retention during the twentieth century. Our results show that these projections are sensitive to the dynamics considered and the terrestrial-water corrections applied. For B1, which is a moderate climate-change scenario, the lowest semi-empirical projection of sea-level rise over the twenty-first century equals 62+/-14cm. The average value is substantially smaller than previously published semi-empirical projections and is therefore closer to the corresponding process-based values. The standard deviation is larger than the uncertainties of process-based estimates.

    Using the set of simulations performed with atmosphere-ocean general circulation models (AOGCMs) for the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4), the projected regional distribution of sea ice for the twenty-first century has been investigated. Averaged over all those model simulations, the current climate is reasonably well reproduced. However, this averaging procedure hides the errors from individual models. Over the twentieth century, the multimodel average simulates a larger sea-ice concentration decrease around the Antarctic Peninsula compared to other regions, which is in qualitative agreement with observations. This is likely related to the positive trend in the Southern Annular Mode (SAM) index over the twentieth century, in both observations and in the multimodel average. Despite the simulated positive future trend in SAM, such a regional feature around the Antarctic Peninsula is absent in the projected sea-ice change for the end of the twenty-first century. The maximum decrease is indeed located over the central Weddell Sea and the Amundsen-Bellingshausen Seas. In most models, changes in the oceanic currents could play a role in the regional distribution of the sea ice, especially in the Ross Sea, where stronger southward currents could be responsible for a smaller sea-ice decrease during the twenty-first century. Finally, changes in the mixed layer depth can be found in some models, inducing locally strong changes in the sea-ice concentration. (orig.)

    Uncertainty in the strength of the Atlantic Meridional Overturning Circulation (AMOC) is analyzed in the Coupled Model Intercomparison Project Phase 3 (CMIP3) and Phase 5 (CMIP5) projections for the twenty-first century; and the different sources of uncertainty (scenario, internal and model) are quantified. Although the uncertainty in future projections of the AMOC index at 30°N is larger in CMIP5 than in CMIP3, the signal-to-noise ratio is comparable during the second half of the century and even larger in CMIP5 during the first half. This is due to a stronger AMOC reduction in CMIP5. At lead times longer than a few decades, model uncertainty dominates uncertainty in future projections of AMOC strength in both the CMIP3 and CMIP5 model ensembles. Internal variability significantly contributes only during the first few decades, while scenario uncertainty is relatively small at all lead times. Model uncertainty in future changes in AMOC strength arises mostly from uncertainty in density, as uncertainty arising from wind stress (Ekman transport) is negligible. Finally, the uncertainty in changes in the density originates mostly from the simulation of salinity, rather than temperature. High-latitude freshwater flux and the subpolar gyre projections were also analyzed, because these quantities are thought to play an important role for the future AMOC changes. The freshwater input in high latitudes is projected to increase and the subpolar gyre is projected to weaken. Both the freshening and the gyre weakening likely influence the AMOC by causing anomalous salinity advection into the regions of deep water formation. While the high model uncertainty in both parameters may explain the uncertainty in the AMOC projection, deeper insight into the mechanisms for AMOC is required to reach a more quantitative conclusion.

    Full Text Available During last two decades, several photon counting detectors have been developed in our laboratory. One of the most promising detector coming from our group silicon K14 Single Photon Avalanche Diode (SPAD is presented with its valuable features and space applications. Based on the control electronics, it can be operated in both gated and non-gated mode. Although it was designed for photon counting detection, it can be employed for multiphoton detection as well. With respect to control electronics employed, the timing jitter can be as low as 20 ps RMS. Detection efficiency is about 40%in range of 500 nm to 800 nm. The detector including gating and quenching circuitry has outstanding timing stability. Due to its radiation resistivity, the diode withstands 100 krad gamma ray dose without parameters degradation. Single photon detectors based on K14 SPAD were used for planetary altimeter and atmospheric lidar in MARS92/96 and Mars Surveyor ’98 space projects, respectively. Recent space applications of K14 SPAD comprises LIDAR and mainly time transfer between ground stations and artificial satellites. These include Laser Time Transfer, Time Transfer by Laser Link, and European Laser Timing projects.

  14. Twenty-first century projected summer mean climate in the Mediterranean interpreted through the monsoon-desert mechanism

    2016-10-01

    The term "monsoon-desert mechanism" indicates the relationship between the diabatic heating associated with the South Asian summer monsoon rainfall and the remote response in the western sub-tropics where long Rossby waves anchor strong descent with high subsidence. In CMIP5 twenty-first century climate scenarios, the precipitation over South Asia is projected to increase. This study investigates how this change could affect the summer climate projections in the Mediterranean region. In a linear framework the monsoon-desert mechanism in the context of climate change would imply that the change in subsidence over the Mediterranean should be strongly linked with the changes in South Asian monsoon precipitation. The steady-state solution from a linear model forced with CMIP5 model projected precipitation change over South Asia shows a broad region of descent in the Mediterranean, while the results from CMIP5 projections differ having increased descent mostly in the western sector but also decreased descent in parts of the eastern sector. Local changes in circulation, particularly the meridional wind, promote cold air advection that anchors the descent but the barotropic Rossby wave nature of the wind anomalies consisting of alternating northerlies/southerlies favors alternating descent/ascent locations. In fact, the local mid-tropospheric meridional wind changes have the strongest correlation with the regions where the difference in subsidence is largest. There decreased rainfall is mostly balanced by changes in moisture, omega and in the horizontal advection of moisture.

    Full Text Available The Lajta Project covers 3,065 ha. Within this area crop cultivation is dominant. Fields are separated from each other by forest belts and tree rows, extending altogether over roughly 120 ha. This habitat structure characterized by cultivation of 12–15 field crops sustained partridge population with densities of 1.75 birds/km2 (1991. The Project started in 1991/1992 and aimed to increase the carrying capacity for grey partridge and other small game species living in the area. A full–time gamekeeper was employed and habitat improvements were initiated. Four years later, the breeding population increased to 10.1 birds/km2. Besides increased numbers of nesting pairs, the number of reared chicks also increased, from 5.1–11.2 individuals/km2 in 1990 to 27.3–38.4 individuals/km2 in 1994. However, field sizes did not change significantly. Although the lengths of field margins increased by approximately 25% (from 82 m/ha to 115 m/ha under the influence of habitat management, they still reached only half those found in the countries of Central Europe where private ownership of land properties is dominant. After the privatisation of fields in 1995 as part of the political change in Hungary —affecting approximately 50% of the project area— the possibilities of habitat improvement decreased, and the technological pressure on large–scale farming area increased. Following these processes the grey partridge population again decreased to 1.43 birds/km2 in 1997. As a result of the new management strategy applied in the project since 1996 we observed a slow increase in the breeding population, which stabilized at around 5 birds/km2, between 2007 and 2009. The August density increased in the same period from 4.5 birds/km2 to 13–17 birds/km2. During the two decades in which this research was conducted, chick mortality and winter mortality were extremely high. The key factors influencing grey partridge population dynamics in our study area seem to be

    Full Text Available Many sources such as the immaturity, complexity and unpredictable evolution of the technologies themselves, and the difficulty of predicting the market demand generally cause uncertainty in the Information Technology (IT projects. Managerial flexibility has value in the context of uncertain IT projects, as management can continuously gather information about uncertain project and market characteristics and, based on this information, change its course of action. As traditional capital budgeting (or project appraisal approaches fail to consider embedded managerial flexibility in projects, the new investment evaluation approach called “real options” has come on the scene recently. “Options thinking,” an emerging investment management philosophy based on the theory of financial options can provide a promising foundation for hedging the risks under uncertainty. This paper aims at analyzing a real IT investment having growth opportunities by using real options approach. Specifically, the value of investing in a software project as well as embedded flexibility in this opportunity is modeled as an option contract. The expected costs required for completing the project and thereafter the resulting asset value are considered as the base-case parameters of this contract. Option values derived from Binomial method are used for evaluating the project and the optimal investment policy is determined based on these values. As a result, it is shown that the value of an IT project having flexibility can differ from one obtained with traditional capital budgeting methods and a rejected project which was seen as unprofitable before can turn a profitable one through embedded flexibilities.

    Sea-level change is often considered to be globally uniform in sea-level projections. However, local relative sea-level (RSL) change can deviate substantially from the global mean. Here, we present maps of twenty-first century local RSL change estimates based on an ensemble of coupled climate model simulations for three emission scenarios. In the Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4), the same model simulations were used for their projections of global mean sea-level rise. The contribution of the small glaciers and ice caps to local RSL change is calculated with a glacier model, based on a volume-area approach. The contributions of the Greenland and Antarctic ice sheets are obtained from IPCC AR4 estimates. The RSL distribution resulting from the land ice mass changes is then calculated by solving the sea-level equation for a rotating, elastic Earth model. Next, we add the pattern of steric RSL changes obtained from the coupled climate models and a model estimate for the effect of Glacial Isostatic Adjustment. The resulting ensemble mean RSL pattern reveals that many regions will experience RSL changes that differ substantially from the global mean. For the A1B ensemble, local RSL change values range from -3.91 to 0.79 m, with a global mean of 0.47 m. Although the RSL amplitude differs, the spatial patterns are similar for all three emission scenarios. The spread in the projections is dominated by the distribution of the steric contribution, at least for the processes included in this study. Extreme ice loss scenarios may alter this picture. For individual sites, we find a standard deviation for the combined contributions of approximately 10 cm, regardless of emission scenario. (orig.)

    The global wave-induced current (the Stokes Drift - SD) is an important feature of the ocean surface, with mean values close to 10 cm/s along the extra-tropical storm tracks in both hemispheres. Besides the horizontal displacement of large volumes of water the SD also plays an important role in the ocean mix-layer turbulence structure, particularly in stormy or high wind speed areas. The role of the wave-induced currents in the ocean mix-layer and in the sea surface temperature (SST) is currently a hot topic of air-sea interaction research, from forecast to climate ranges. The SD is mostly driven by wind sea waves and highly sensitive to changes in the overlaying wind speed and direction. The impact of climate change in the global wave-induced current climate will be presented. The wave model WAM has been forced by the global climate model (GCM) ECHAM5 wind speed (at 10 m height) and ice, for present-day and potential future climate conditions towards the end of the end of the twenty-first century, represented by the Intergovernmental Panel for Climate Change (IPCC) CMIP3 (Coupled Model Inter-comparison Project phase 3) A1B greenhouse gas emission scenario (usually referred to as a ''medium-high emissions'' scenario). Several wave parameters were stored as output in the WAM model simulations, including the wave spectra. The 6 hourly and 0.5°×0.5°, temporal and space resolution, wave spectra were used to compute the SD global climate of two 32-yr periods, representative of the end of the twentieth (1959-1990) and twenty-first (1969-2100) centuries. Comparisons of the present climate run with the ECMWF (European Centre for Medium-Range Weather Forecasts) ERA-40 reanalysis are used to assess the capability of the WAM-ECHAM5 runs to produce realistic SD results. This study is part of the WRCP-JCOMM COWCLIP (Coordinated Ocean Wave Climate Project) effort.

    Project ImPACT is a Naturalistic Developmental Behavioral Intervention (NDBI) for young children with ASD. Preliminary research supports its feasibility and efficacy as a parent-mediated intervention; however, its efficacy as a low-intensity, therapist-implemented intervention is unclear. A single-case, multiple-baseline design evaluated the effect of 2 h per week of therapist-implemented Project ImPACT on social engagement, language, and play in nine children with ASD. Language and play skills were targeted separately for five children and together for four children. Children increased their rates of social engagement and language when language or play was the sole target and when language and play were targeted together; however, gains in play skills were evident only when they were targeted separately. This study provides support for the efficacy of the Project ImPACT when implemented by therapists at a low intensity and suggests the way in which skills are targeted can affect child learning.

  2. Establishing a Dynamic Database of Blue and Fin Whale Locations from Recordings at the IMS CTBTO hydro-acoustic network. The Baleakanta Project

    Falling as they do into the frequency range of continuously recording hydrophones (15-100Hz), blue and fin whale songs are a significant source of noise on the hydro-acoustic monitoring array of the International Monitoring System (IMS) of the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO). One researcher's noise, however, can be a very interesting signal in another field of study. The aim of the Baleakanta Project (www.baleakanta.org) is to flag and catalogue these songs, using the azimuth and slowness of the signal measured at multiple hydrophones to solve for the approximate location of singing whales. Applying techniques borrowed from human speaker identification, it may even be possible to recognize the songs of particular individuals. The result will be a dynamic database of whale locations and songs with known individuals noted. This database will be of great value to marine biologists studying cetaceans, as there is no existing dataset which spans the globe over many years (more than 15 years of data have been collected by the IMS). Current whale song datasets from other sources are limited to detections made on small, temporary listening devices. The IMS song catalogue will make it possible to study at least some aspects of the global migration patterns of whales, changes in their songs over time, and the habits of individuals. It is believed that about 10 blue whale 'cultures' exist with distinct vocal patterns; the IMS song catalogue will test that number. Results and a subset of the database (delayed in time to mitigate worries over whaling and harassment of the animals) will be released over the web. A traveling museum exhibit is planned which will not only educate the public about whale songs, but will also make the CTBTO and its achievements more widely known. As a testament to the public's enduring fascination with whales, initial funding for this project has been crowd-sourced through an internet campaign.

    In addition to projected increases in global mean sea level over the 21st century, model simulations suggest there will also be changes in the regional distribution of sea level relative to the global mean. There is a considerable spread in the projected patterns of these changes by current models, as shown by the recent Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment (AR4). This spread has not reduced from that given by the Third Assessment models. Comparison with projections by ensembles of models based on a single structure supports an earlier suggestion that models of similar formulation give more similar patterns of sea level change. Analysing an AR4 ensemble of model projections under a business-as-usual scenario shows that steric changes (associated with subsurface ocean density changes) largely dominate the sea level pattern changes. The relative importance of subsurface temperature or salinity changes in contributing to this differs from region to region and, to an extent, from model-to-model. In general, thermosteric changes give the spatial variations in the Southern Ocean, halosteric changes dominate in the Arctic and strong compensation between thermosteric and halosteric changes characterises the Atlantic. The magnitude of sea level and component changes in the Atlantic appear to be linked to the amount of Atlantic meridional overturning circulation (MOC) weakening. When the MOC weakening is substantial, the Atlantic thermosteric patterns of change arise from a dominant role of ocean advective heat flux changes. (orig.)

    We use two CORDEX-Africa simulations performed with the regional model RegCM4 to characterize the projected changes in extremes and hydroclimatic regimes associated with the West African Monsoon (WAM). RegCM4 was driven for the period 1970-2100 by the HadGEM2-ES and the MPI-ESM Global Climate Models (GCMs) under the RCP8.5 greenhouse gas concentration pathway. RegCM4 accurately simulates the WAM characteristics in terms of seasonal mean, seasonal cycle, interannual variability and extreme events of rainfall. Overall, both RegCM4 experiments are able to reproduce the large-scale atmospheric circulation for the reference period (i.e. present-day), and in fact show improved performance compared to the driving GCMs in terms of precipitation mean climatology and extreme events, although different shortcomings in the various models are still evident. Precipitation is projected to decrease (increase) over western (eastern) Sahel, although with different spatial detail between RegCM4 and the corresponding driving GCMs. Changes in extreme precipitation events show patterns in line with those of the mean change. The models project different changes in water budget over the Sahel region, where the MPI projects an increased deficit in local moisture supply (E P). The E-P change is primarily precipitation driven. The precipitation increases over the eastern and/or central Sahel are attributed to the increase of moisture convergence due to increased water vapor in the boundary layer air column and surface evaporation. On the other hand, the projected dry conditions over the western Sahel are associated with the strengthening of moisture divergence in the upper level (850-300 hPa) combined to both a southward migration of the African Easterly Jet (AEJ) and a weakening of rising motion between the core of the AEJ and the Tropical Easterly Jet.

    Ireland has a highly energetic wave and wind climate, and is therefore uniquely placed in terms of its ocean renewable energy resource. The socio-economic importance of the marine resource to Ireland makes it critical to quantify how the wave and wind climate may change in the future due to global climate change. Projected changes in winds, ocean waves and the frequency and severity of extreme weather events should be carefully assessed for long-term marine and coastal planning. We derived an ensemble of future wave climate projections for Ireland using the EC-Earth global climate model and the WAVEWATCH III® wave model, by comparing the future 30-year period 2070-2099 to the period 1980-2009 for the RCP4.5 and the RCP8.5 forcing scenarios. This dataset is currently the highest resolution wave projection dataset available for Ireland. The EC-Earth ensemble predicts decreases in mean (up to 2 % for RCP4.5 and up to 3.5 % for RCP8.5) 10 m wind speeds over the North Atlantic Ocean (5-75° N, 0-80° W) by the end of the century, which will consequently affect swell generation for the Irish wave climate. The WAVEWATCH III® model predicts an overall decrease in annual and seasonal mean significant wave heights around Ireland, with the largest decreases in summer (up to 15 %) and winter (up to 10 %) for RCP8.5. Projected decreases in mean significant wave heights for spring and autumn were found to be small for both forcing scenarios (less than 5 %), with no significant decrease found for RCP4.5 off the west coast in those seasons.

    Changes in mass contained by mountain glaciers and ice caps can modify the Earth's hydrological cycle on multiple scales. On a global scale, the mass loss from glaciers contributes to sea level rise. On regional and local scales, glacier melt-water is an important contributor to and modulator of river flow. In this study we use an elevation-dependent glacier mass balance model to project annual volume changes and monthly runoff from all mountain glaciers and ice caps in the world (excluding those in the Antarctic periphery) for the 21st century forced by temperature and precipitation scenarios from 14 global climate models. The largest contributors to projected total volume loss are the glaciers in the Canadian and Russian Arctic, Alaska and glaciers peripheral to Greenland ice sheet. Although small contributors to global volume loss, glaciers in Central Europe, low-latitude South America, Caucasus, North Asia, and Western Canada and US are projected to lose more than 75% of their volume by 2100. The magnitude and sign of trends in annual runoff totals differ considerably among regions depending on the balance between enhanced melt and the reduction of the glacier reservoir by glacier retreat and shrinkage. Most regions show strong declines in glacier runoff indicating that the effect of glacier shrinkage is more dominant than increased melting rates. Some high-latitude regions (Arctic Canada North, Russian Arctic and Greenland) exhibit increases in runoff totals. Iceland and Svalbard show an increase in runoff followed by a multi-decadal decrease in annual runoff.

    Due to the importance that the El Niño-Southern Oscillation (ENSO) has on rainfall over the tropical Americas, future changes in ENSO characteristics and teleconnections are important for regional hydroclimate. Projected changes to the ENSO mean state and characteristics, and the resulting impacts on rainfall anomalies over Central America, Colombia, and Ecuador during the twenty-first century are explored for several forcing scenarios using a suite of coupled atmosphere-ocean global climate models (AOGCMs) from the fifth phase of the Coupled Model Intercomparison Project (CMIP5). Mean-state warming of eastern tropical Pacific sea surface temperatures, drying of Central America and northern Colombia, and wetting of southwest Colombia and Ecuador are consistent with previous studies that used earlier versions of the AOGCMs. Current and projected future characteristics of ENSO (frequency, duration, amplitude) show a wide range of values across the various AOGCMs. The magnitude of ENSO-related rainfall anomalies are currently underestimated by most of the models, but the model ensembles generally simulate the correct sign of the anomalies across the seasons around the peak ENSO effects. While the models capture the broad present-day ENSO-related rainfall anomalies, there is not a clear sense of projected future changes in the precipitation anomalies.

    this study aims at presenting the results from the Italian EpiaAir2 Project on the short-term effects of air pollution on adult population (35+ years old) in 25 Italian cities. the short-term effects of air pollution on resident people died in their city were analysed adopting the time series approach. The association between increases in 10µg/m(3) in PM10, PM2.5, NO2 and O3 air concentration and natural, cardiac, cerebrovascular and respiratory mortality was studied. City-specific Poisson models were fitted to estimate the association of daily concentrations of pollutants with daily counts of deaths. The analysis took into account temporal and meteorological factors to control for potential confounding effect. Pooled estimates have been derived from random effects meta-analysis, evaluating the presence of heterogeneity in the city specific results. it was analysed 422,723 deaths in the 25 cities of the project among people aged 35 years or more, resident in each city during the period 2006-2010. daily counts of natural, cardiac, cerebrovascular, and respiratory mortality, obtained from the registries of each city. Demographic information were obtained by record linkage procedure with the civil registry of each city. mean number of deaths for natural causes ranged from 513 in Rovigo to 20,959 in Rome. About 25% of deaths are due to cardiac diseases, 10% to cerebrovascular diseases, and 7% to respiratory diseases. It was found an immediate effect of PM10 on natural mortality (0.51%; 95%CI 0.16-0.86; lag 0-1). More relevant and prolonged effects (lag 0-5) have been found for PM2.5 (0.78%; 95%CI 0.12-1.46) and NO2 (1.10%; 95%CI 0.63-1.58). Increases in cardiac mortality are associated with PM10 (0.93%; 95%CI 0.16-1.70) and PM2.5 (1.25%; 95%CI 0.17-2.34), while for respiratory mortality exposure to NO2 has an important role (1.67%; 95%CI 0.23-3.13; lag 2-5), as well as PM10 (1.41%; 95%CI - 0.23;+3.08). Results are strongly homogeneous among cities, except for

    The fast increasing share of dispersed generation, quality regulation and decreasing cost for information and communication technology will most probably lead to increased monitoring and automation in secondary distribution. A central question in this field is to which extent intelligent secondary substations will be utilized and how the technical concepts will look like. Furthermore new applications in network management are necessary to benefit from the new measurement and control functionalities in the grid. One part of this is the integration of measurements from smart meters into the grid operation. The pilot project 'RiesLing' (Projekt im Ries - Leittechnik intelligent gemacht, translated ''implementation of an intelligent grid contol in the Ries area'') aims to develop optimized technical solutions for the mentioned areas and to test the practical implementation within the grid of EnBW ODR. The region of its implementation is the Noerdlinger Ries, a region in the north-western part of Bavaria and in close vicinity to the federal state of Baden-Wuerttemberg. This area combines a maximum load of around 50 MW with a maximum generation of around 120 MW, mostly from Photovoltaic modules and biogas fuelled engines. The RiesLing project has been initiated in mid 2011. Its technical implementation, set up as 3 packages, will be finished until end of 2012. The implementation phase will be followed by a practical test phase to optimize the technical solution and to derive practical operation experience. The project thus will end by December 2013. The paper shows the solutions and concepts for secondary substations which are developed within the project. (orig.)

    This study analyzes the impact of anthropogenic climate change in the hydroclimatology of Senegal with a focus over the lake of Guiers basin for the middle (2041-2060) and late twenty-first century (2080-2099). To this end, high-resolution multimodel ensemble based on regional climate model experiments considering two Representative Concentration Pathways (RCP4.5 and RCP8.5) is used. The results indicate that an elevated warming, leading to substantial increase of atmospheric water demand, is projected over the whole of Senegal. In the Lake basin, these increases in potential evapotranspiration (PE) range between 10 and 25 % in the near future and for RCP4.5 while for the far future and RCP8.5, they exceed 50 %. In addition, mean precipitation unveils contrasting changes with wetter (10 to 25 % more) conditions by the middle of the century and drier conditions (more than 50 %) during the late twenty-first century. Such changes cause more/less evapotranspiration and soil moisture respectively during the two future periods. Furthermore, surface runoff shows a tendency to increase in most areas amid few locations including the Lake basin with substantial reduction. Finally, it is found that while semi-arid climates develop in the RCP4.5 scenario, generalized arid conditions prevail over the whole Senegal for RCP8.5. It is thus evident that these future climate conditions substantially threaten freshwater availability for the country and irrigated cropping over the Lake basin. Therefore, strong governmental politics are needed to help design response options to cope with the challenges posed by the projected climate change for the country.

    This paper provides a first overview of the performance of global climate models participating in the Coupled Model Inter-Comparison Project phase 5 (CMIP5) in simulating the upper troposphere and lower stratosphere (UTLS) temperatures. Temperature from CMIP5 models is evaluated with high resolution global positioning system radio occultation (GPSRO) constellation observing system for meteorology, ionosphere, and climate (COSMIC) data during the period of July 2006-December 2013. Future projections of 17 CMIP5 models based on the representative concentration pathway (RCP) 8.5 scenarios are utilized to assess model performance and to identify the biases in the temperature in the UTLS region at eight different pressure levels. The evaluations were carried out vertically, regionally, and globally to understand the temperature uncertainties in CMIP5 models. It is found that the CMIP5 models successfully reproduce the general features of temperature structure in terms of vertical, annual, and inter-annual variation. The ensemble mean of CMIP5 models compares well with the COSMIC GPSRO data with a mean difference of ±1 K. In the tropical region, temperature biases vary from one model to another. The spatial difference between COSMIC and ensemble mean reveals that at 100 hPa, the models show a bias of about ±2 K. With increase in altitude the bias decreases and turns into a cold bias over the tropical and Antarctic regions. The future projections of the CMIP5 models were presented during 2006-2099 under the RCP 8.5 scenarios. Projections show a warming trend at 300, 200, and 100 hPa levels over a wide region of 60°N-45°S. The warming decreases rapidly and becomes cooling with increase in altitudes by the end of twenty-first century. Significant cooling is observed at 30, 20, and 10 hPa levels. At 300/10 hPa, the temperature trend increases/decreases by 0.82/0.88 K/decade at the end of twenty-first century under RCP 8.5 scenarios.

    An assessment of future change in synoptic conditions over the Arabian Peninsula throughout the twenty-first century was performed using 20 climate models from the Coupled Model Intercomparison Project Phase 5 (CMIP5) database. We employed the mean sea level pressure (SLP) data from model output together with NCEP/NCAR reanalysis data and compared the relevant circulation types produced by the Lamb classification scheme for the base period 1975-2000. Overall, model results illustrated good agreement with the reanalysis, albeit with a tendency to underestimate cyclonic (C) and southeasterly (SE) patterns and to overestimate anticyclones and directional flows. We also investigated future projections for each circulation-type during the rainy season (December-May) using three Representative Concentration Pathways (RCPs), comprising RCP2.6, RCP4.5, and RCP8.5. Overall, two scenarios (RCP4.5 and RCP 8.5) revealed a statistically significant increase in weather types favoring above normal rainfall in the region (e.g., C and E-types). In contrast, weather types associated with lower amounts of rainfall (e.g., anticyclones) are projected to decrease in winter but increase in spring. For all scenarios, there was consistent agreement on the sign of change (i.e., positive/negative) for the most frequent patterns (e.g., C, SE, E and A-types), whereas the sign was uncertain for less recurrent types (e.g., N, NW, SE, and W). The projected changes in weather type frequencies in the region can be viewed not only as indicators of change in rainfall response but may also be used to inform impact studies pertinent to water resource planning and management, extreme weather analysis, and agricultural production.

    A terrestrial ecosystem model (Sim-CYCLE) was driven by multiple climate projections to investigate uncertainties in predicting the interactions between global environmental change and the terrestrial carbon cycle. Sim-CYCLE has a spatial resolution of 0.5 , and mechanistically evaluates photosynthetic and respiratory CO{sub 2} exchange. Six scenarios for atmospheric-CO{sub 2} concentrations in the twenty-first century, proposed by the Intergovernmental Panel on Climate Change, were considered. For each scenario, climate projections by a coupled atmosphere-ocean general circulation model (AOGCM) were used to assess the uncertainty due to socio-economic predictions. Under a single CO{sub 2} scenario, climate projections with seven AOGCMs were used to investigate the uncertainty stemming from uncertainty in the climate simulations. Increases in global photosynthesis and carbon storage differed considerably among scenarios, ranging from 23 to 37% and from 24 to 81 Pg C, respectively. Among the AOGCM projections, increases ranged from 26 to 33% and from 48 to 289 Pg C, respectively. There were regional heterogeneities in both climatic change and carbon budget response, and different carbon-cycle components often responded differently to a given environmental change. Photosynthetic CO{sub 2} fixation was more sensitive to atmospheric CO{sub 2}, whereas soil carbon storage was more sensitive to temperature. Consequently, uncertainties in the CO{sub 2} scenarios and climatic projections may create additional uncertainties in projecting atmospheric-CO{sub 2} concentrations and climates through the interactive feedbacks between the atmosphere and the terrestrial ecosystem.

    The knowledge of ocean surface wave energy fluxes (or wave power) is of outmost relevance since wave power has a direct impact in coastal erosion, but also in sediment transport and beach nourishment, and ship, as well as in coastal and offshore infrastructures design. Changes in the global wave energy flux pattern can alter significantly the impact of waves in continental shelf and coastal areas. Up until recently the impact of climate change in future global wave climate had received very little attention. Some single model single scenario global wave climate projections, based on CMIP3 scenarios, were pursuit under the auspices of the COWCLIP (coordinated ocean wave climate projections) project, and received some attention in the IPCC (Intergovernmental Panel for Climate Change) AR5 (fifth assessment report). In the present study the impact of a warmer climate in the near future global wave energy flux climate is investigated through a 4-member "coherent" ensemble of wave climate projections: single-model, single-forcing, and single-scenario. In this methodology model variability is reduced, leaving only room for the climate change signal. The four ensemble members were produced with the wave model WAM, forced with wind speed and ice coverage from EC-Earth projections, following the representative concentration pathway with a high emissions scenario 8.5 (RCP8.5). The ensemble present climate reference period (the control run) has been set for 1976 to 2005. The projected changes in the global wave energy flux climate are analyzed for the 2031-2060 period.

    Projected changes in the relative abundance and timing of autumn-winter migration are assessed for seven dabbling duck species across the Mississippi and Atlantic Flyways for the mid- and late 21st century. Species-specific observed relationships are established between cumulative weather severity in autumn-winter and duck population rate of change. Dynamically downscaled projections of weather severity are developed using a high-resolution regional climate model, interactively coupled to a one-dimensional lake model to represent the Great Lakes and associated lake-effect snowfall. Based on the observed relationships and downscaled climate projections of rising air temperatures and reduced snow cover, delayed autumn-winter migration is expected for all species, with the least delays for the Northern Pintail and the greatest delays for the Mallard. Indeed, the Mallard, the most common and widespread duck in North America, may overwinter in the Great Lakes region by the late 21st century. This highlights the importance of protecting and restoring wetlands across the mid-latitudes of North America, including the Great Lakes Basin, because dabbling ducks are likely to spend more time there, which would impact existing wetlands through increased foraging pressure. Furthermore, inconsistency in the timing and intensity of the traditional autumn-winter migration of dabbling ducks in the Mississippi and Atlantic Flyways could have social and economic consequences to communities to the south, where hunting and birdwatching would be affected.

  13. Winter weather regimes over the Mediterranean region: their role for the regional climate and projected changes in the twenty-first century

    The winter time weather variability over the Mediterranean is studied in relation to the prevailing weather regimes (WRs) over the region. Using daily geopotential heights at 700 hPa from the ECMWF ERA40 Reanalysis Project and Cluster Analysis, four WRs are identified, in increasing order of frequency of occurrence, as cyclonic (22.0 %), zonal (24.8 %), meridional (25.2 %) and anticyclonic (28.0 %). The surface climate, cloud distribution and radiation patterns associated with these winter WRs are deduced from satellite (ISCCP) and other observational (E-OBS, ERA40) datasets. The LMDz atmosphere-ocean regional climate model is able to simulate successfully the same four Mediterranean weather regimes and reproduce the associated surface and atmospheric conditions for the present climate (1961-1990). Both observational- and LMDz-based computations show that the four Mediterranean weather regimes control the region's weather and climate conditions during winter, exhibiting significant differences between them as for temperature, precipitation, cloudiness and radiation distributions within the region. Projections (2021-2050) of the winter Mediterranean weather and climate are obtained using the LMDz model and analysed in relation to the simulated changes in the four WRs. According to the SRES A1B emission scenario, a significant warming (between 2 and 4 °C) is projected to occur in the region, along with a precipitation decrease by 10-20 % in southern Europe, Mediterranean Sea and North Africa, against a 10 % precipitation increase in northern European areas. The projected changes in temperature and precipitation in the Mediterranean are explained by the model-predicted changes in the frequency of occurrence as well as in the intra-seasonal variability of the regional weather regimes. The anticyclonic configuration is projected to become more recurrent, contributing to the decreased precipitation over most of the basin, while the cyclonic and zonal ones become more

  14. Leptin im Knochenstoffwechsel

    2003-01-01

    Full Text Available Leptin ist ein in Adipozyten exprimiertes Hormon mit vielfältigen Funktionen im gesamten Organismus. Verschiedene Studien legen eine positive Wirkung von Leptin auf den Knochenstoffwechsel nahe. In vitro führte die Inkubation von Knochenmarkstromazellen mit Leptin zu deren Differenzierung zu Osteoblasten und Mineralisation der Matrix. Bei ovarektomierten Ratten konnte durch Leptin der Knochenverlust vermindert werden. Überraschenderweise zeigten andere Studien eine zentrale inhibitorische Wirkung von Leptin auf Osteoblasten bei Nagern. Diese einander scheinbar widersprechenden Ergebnisse zeigen, daß die molekularen Mechanismen, mit welchen Leptin auf den Knochenstoffwechsel wirkt, noch nicht ausreichend verstanden werden. In klinischen Studien findet sich eine protektive Wirkung von Fettmasse und "body mass index" (BMI auf die Knochendichte (postmenopausaler Frauen überwiegend bestätigt. Damit im Einklang, konnten erhöhte Leptinspiegel gefunden werden. Ob Leptin nun direkt in den Knochenstoffwechsel eingreift oder bloß indirekt etwa über eine erhöhte mechanische Belastung, läßt sich aus klinischen Studien allein nicht beantworten. Hingegen dürfte Leptin im Knochenstoffwechsel von Männern keine oder nur eine untergeordnete Rolle spielen. Die Situation bei Kindern und Jugendlichen ist noch unklar, wobei eine positive Wirkung von Leptin in fetalem Knochen relativ sicher ist. Leptin könnte jedoch auch im Wachstum und der Knochenreifung bei Kindern und Jugendlichen eine Rolle spielen.

    The aim of this study is to assess the impact of land-use and land-cover change (LULCC) on regional climate projections for North America. To this end, two transient climate change simulations, with and without LULCC, but identical atmospheric forcing, are performed with the 5th generation of the Canadian Regional Climate Model (CRCM5) driven by CanESM2 model for the (2006-2100)-RCP4.5 scenario. For the simulation with LULCC, land-cover data sets are taken from the Global Change Assessment Model representing the RCP4.5 scenario for the period 2006-2100. LULCC in RCP4.5 scenario point to significant reduction in cultivated land (e.g. Canadian Prairies and Mississippi basin) due to intense afforestation. Results suggest that biogeophysical effects of LULCC on climate, assessed through differences between the all-forcing (atmospheric and LULCC) run and the atmospheric forcing run (with constant land cover) are substantial for relevant surface variables. It is shown that the afforestation of cropland lead to warmer regional climates, especially in winter (warming above 1.5 °C), as compared with climates resulting from atmospheric forcings alone. The investigation of processes leading to this response shows high sensitivity of the results to changes in albedo as a response to LULCC. Additional roughness, evaporative cooling and water soil availability also seem to play an important role in regional climate especially for the summer season in certain afforested areas (e.g., southeastern US).

Eines der Fährnisse ist das Verhältnis zwischen bildlichen und schriftlichen Anteilen: Nicht selten wird der künstlerische Anteil zur Illustration der dominierenden Schrift. Eine Neupositionierung des Bildes im Buch ist nun der amerikanischen Künstlerin Roni Horn gelungen. Mehr als „sujet“ ihres Buches, ist die französische Philosophin Hélène Cixous gleichsam instruierende „Stimme“, die im Bild aufscheint.

    It is essential that a critical examination of the question of civic participation in resettlement projects should include all communication sectors, that is to say, information, consulting, counselling and cooperation. An adequate communiction system is of decisive importance for the success of resettlement projects. The aim of this communication system is to ensure that the individual person is in a position both to follow and understand the various stages of the project and also to express a definite opinion and voice a decision on the various topics to be dealt with. In order to achieve this aim it is imperative that communication should be oriented to the needs of the population to be resettled and that attractive participation opportunities should be offered, which are in keeping with the overall social conditions and the local situation. With its communication concept of 1997 Rheinbraun not only meets requirements as regards constant checking of the relevant offers, but has also evolved optimization principles for communication that are related to the resettlement project in question as well as being generally applicable.

    The waste and material flow management must align progressively to the requirements of sustainable resource and climate protection targets. She has become a recycling economy. One of the key global challenges of the future is to ensure a sustainable, i.e. economically, environmentally and socially sustainable supply of raw materials and energy. In both areas, the recycling economy make an important contribution. For Germany, despite of the ambitious targets, a positive balance can be drawn. In particular, the positive environmental effects of prevention, recovery and disposal of waste are supported by numerous scientific studies. While the recycling economy has performed well in Germany, many countries in the world are still in the beginning of a sustainable waste management development. Our Chair for Waste and Material Flow Management at the Faculty of Agricultural and Environmental Sciences of the University of Rostock has been involved for over 15 years in international technology and knowledge transfer. The regional focus are the Arab and Asian region (esp. China) and for some years, the Baltic countries, Eastern Europe and South America. Often in the projects stand in the foreground, to inform key decision-makers on the state of technology and to work out possible administrative solutions and customized technical solutions together and implement. In addition, classic R and D projects in these regions have been processed. In the framework of student works, studies in other countries, amongst other things in Vietnam and Chile, are carried out.

    Background: During 2001, persons who attributed their health problems to environmental exposures, e.g. electromagnetic fields (EMF), were counselled in an interdisciplinary environmental medicine pilot project in the Basel area. Methods: All participants had a medical and a psychological-psychiatric examination and were visited at home by an environmental hygienist. High and low frequency EMF measurements were conducted at the homes of those participants who attributed their health complaints specifically to EMF. The plausibility of a relation between health complaints and EMF exposure was discussed in joint case conferences. Plausibility was judged on the basis of the following criteria: EMF levels had to exceed a tenth of the Swiss threshold values to be considered in the case conference (low frequency: 10 V/m, 0.1 {mu}T, high frequency: 0.6 V/m). The exposure had to occur in an area where the participant spent at least several hours or more every day. Prerequisite was that the exposure occurred before the onset of symptoms. Results: 25 of 63 (40%) of participants suspected EMF as cause of their health complaints. All EMF measurements yielded fields below the Swiss threshold values. Despite of the difficulties in assessing an exposure-response relation in an individual case and the controversial scientific evidence related to health effects of EMF exposures, the project team concluded that in 8 of the 25 (32%) participants, at least one of the reported symptoms was plausibly related to the EMF exposure. An evaluation interview half a year after counselling yielded that around 45% of the participants reported that they had benefited from the project and their health problems had improved following participation. Conclusions: Although none of the threshold values was exceeded, the project team rated an EMF exposure a plausible cause of the reported health complaints of few participants. Due to the high complexity in these cases, only an interdisciplinary team is

First described by Moritz Kaposi in 1872, who reported it to be an aggressive skin tumor, KS became known over the next century as a slow-growing tumor of elderly men—in fact, most KS patients were expected to die with the tumor rather than from it. Nevertheless, the course and manifestations of the disease varied widely in different clinical contexts. The puzzle of KS came to the forefront as a harbinger of the AIDS epidemic. The articles in this issue of Viruses recount progress made in understanding Kaposi’s sarcoma herpesvirus (KSHV since its initial description in 1994.

    This report examines the market potential of a miniature, hand-held Ion Mobility Spectrometer. Military and civilian markets are discussed, as well as applications in a variety of diverse fields. The strengths and weaknesses of competing technologies are discussed. An extensive Ion Mobility Spectrometry (IMS) bibliography is included. The conclusions drawn from this study are: (1) There are a number of competing technologies that are capable of detecting explosives, drugs, biological, or chemical agents. The IMS system currently represents the best available compromise regarding sensitivity, specificity, and portability. (2) The military market is not as large as the commercial market, but the military services are more likely to invest R and D funds in the system. (3) Military applications should be addressed before commercial applications are addressed. (4) There is potentially a large commercial market for rugged, hand-held Ion Mobility Spectrometer systems. Commercial users typically do not invest R and D funds in this type of equipment rather, they wait for off-the-shelf availability.

    In den stark automatisierten, arbeitsteiligen Wirtschaftsystemen der Industrienationen ist die eine effiziente und zuverlässige zentrale Informationstechnik (IT) der Unternehmen entscheidend für den Geschäftserfolg. Immer mehr Unternehmensabläufe werden durch die IT unterstützt. Vielfach ist es sogar nur noch durch die umfassende IT-Unterstützung der Geschäftsprozesse möglich, im globalen Wettbewerb erfolgreich zu sein. Die installierte Rechenleistung in modernen Unternehmen steigt dabei ständig an. Neue und verbesserte Anwendungen und Programm-Features erfordern leistungsfähige Server. In den Rechenzentren kleiner und mittlerer Unternehmen sind heute Rechenleistungen installiert, die vor wenigen Jahren ausschließlich einigen Großunternehmen vorbehalten waren. Diese im Grundsatz positive Entwicklung kann aber auch zu hohen Strom- und Kühlleistungen in Rechenzentren führen.

Im Falle des Altgriechischen hätte man eigentlich wenig zu beklagen, denn es mangelt nicht an Material, dazu sind die Texte, die uns zur Verfügung stehen, stilistisch und funktionell verschiedenartig. Es gibt mehrere Gründe, Wortstellung im Altgriechischen zu untersuchen: stilistische Eigenschaften, das Neugriechische sowie das Verhältnis des Altgriechischen zum Indogermanischen. Es liegt zwar auf der Hand, die Untersuchung auf typologischer Grundlage durchzuführen, die Feststellungen, zu denen man auf diese Weiße gelangt, sind jedoch selten schlüssig. Es ist demnach alles andere als leicht, mit solchen Forschungen zuverlässige Ergebnisse zu erzielen.

    2010-10-15

    This publication describes how for the EU states bordering on the Baltic coast energy policy and energy economy have become crucial fields of bilateral and regional cooperation. On the one side this is attributable to the controversial Nord Stream Pipeline, growing concerns over the security of supply, vulnerabilities in energy policy - be they real or imagined - and to competing energy economic interests. On the other side, what has drawn numerous players' attention to the greater Baltic region as an attractive area in terms of energy policy are the prospects for multilateral cooperation projects and associated hopes for greater regional solidarity in issues of energy policy. In this sense the Baltic region is not only an energy political problem zone but also a potential pioneer region, namely when it comes to energy economic and energy political integration within the EU. This ambivalence should continue to characterise the region for the foreseeable future. The extent to which energy economic integration will in future prevail over particular national interests of energy and security policy will greatly depend on the initiatives which the EU Baltic states succeed in launching cooperatively at EU level.

The improvements made to the building are briefly described, which included the rebuilding of its top floor, additional thermal insulation, the replacement of electrical and heating installations and the installation of a mechanical ventilation system with heat recovery. Heating energy is supplied by solar collectors, a heat pump and wood-fired storage ovens. The aims of the result-checking activities and the measurement equipment used are described and the results obtained are discussed in detail. Further, certain problems encountered during the measurement campaign are discussed. The energy flow diagram of the building is presented and its energy consumption compared with the limits set out in the 'Minergie-P' passive-house energy standard.

    The overall objective of this program is to define the effects of impurities, various thermochemical processes, and any impurity-process interactions upon the performance of terrestrial solar cells. The results of the study form a basis for silicon producers, wafer manufacturers, and cell fabricators to develop appropriate cost-benefit relationships for the use of less pure, less costly solar grade silicon. Cr is highly mobile in silicon even at temperatures as low as 600/sup 0/C. Contrasting with earlier data for Mo, Ti, and V, Cr concentrations vary from place to place in polycrystalline silicon wafers and the electrically-active Cr concentration in the polysilicon is more than an order of magnitude smaller than would be projected from single crystal impurity data. We hypothesize that Cr diffuses during ingot cooldown after groth, preferentially segregates to grain boundaries and becomes electrically deactivated. Both Al and Au introduce deep levels when grown into silicon crystals. Accelerated aging data from Ni-contaminated silicon imply that no significant impurity-induced cell performance reduction should be expected over a twenty-year device lifetime. Combined electrical bias and thermal stressing of silicon solar cells containing Nb, Fe, Cu, Ti, Cr, and Ag, respectively produces no performance loss after 100 hour exposures up to 225/sup 0/C. Ti and V, but not Mo, can be gettered from polycrystalline silicon by POCl/sub 3/ or HCl at temperatures of 1000 and 1100/sup 0/C.

    . Spurred by the expanding landings of anchovy, analyses were made on the long-term annual yield of anchovy and discussions raised on the need to introduce some fisheries management regulations in order to avoid over-exploitation and possible collapse of the stock.   This and other management issues dominated the Project during the last 5-year period. Norwegian experts, particularly from the Directorate of Fisheries, have participated in a series of seminar organised by the Bureau of Fisheries covering topics in fisheries management such as management objectives, fisheries law, statistics, inspection and coastal zone management. At the same time, workshops have been held at the Yellow Sea Fisheries Research Institute to prepare assessments of fish resources and provide advice to central government authorities on fisheries management.   Project evaluations have demonstrated that the “Bei Dou” Project in its various phases has made important contributions to the development of fisheries in China. It has also brought together scientists, technicians and administrators from China and Norway in fruitful cooperation, thus expanding their professional and cultural knowledge for mutual benefit.   NORAD has offered to support continued cooperation between fisheries institutions in Norway and China and a Project Document for 2001-2005 has been prepared. The Project will during the nearest years provide information on the Norwegian experience related to establishing and managing fisheries in Exclusive Economic Zones.   This will continue the well-established fisheries cooperation beyond the twenty years marked by the present “Bei Dou” Seminar in Qingdao.

    Full Text Available Die Chromoendoskopie umfaßt diverse intravitale Färbemethoden der Schleimhaut des Gastrointestinaltrakts zur besseren Diagnostik von pathologischen Läsionen. Diese Methoden helfen insbesondere in der Erkennung von frühen gastrointestinalen Neoplasien und Präkanzerosen. Die gängigsten Techniken sind die Färbung des Plattenepithels des Ösophagus mit Lugol’scher Lösung zur Detektion von Karzinomen und intraepithelialen Neoplasien. Methylenblau wird vor allem zur Erfassung einer Barrett-Mukosa und frühen Malignomen in diesem Bereich eingesetzt. Indigokarmin führt zu einer Verstärkung des Oberflächenreliefs der Schleimhaut und verbessert die Erkennung von flachen Läsionen im Gastrointestinaltrakt. Crysylviolett wird wie Indigokarmin gemeinsam mit der Vergrößerungsendoskopie zur endoskopischen Dignitätsbeurteilung von Kolonläsionen mittels Pit-Pattern-Bestimmung eingesetzt. Chromoendokopische Methoden sind einfach in der Anwendung, die Interpretation erfordert jedoch eine spezielle Erfahrung des Endoskopikers.

  12. A New IMS Based Inter-working Solution

    Science.gov (United States)

    Zhu, Zhongwen; Brunner, Richard

    With the evolution of third generation network, more and more multimedia services are developed and deployed. Any new service to be deployed in IMS network is required to inter-work with existing Internet communities or legacy terminal users in order to appreciate the end users, who are the main drivers for the service to succeed. The challenge for Inter-working between IMS (IP Multimedia Subsystem) and non-IMS network is “how to handle recipient’s address”. This is because each network has its own routable address schema. For instance, the address for Google Talk user is xmpp:xyz@google.com, which is un-routable in IMS network. Hereafter a new Inter-working (IW) solution between IMS and non-IMS network is proposed for multimedia services that include Instant Messaging, Chat, and File transfer, etc. It is an end-to-end solution built on IMS infrastructure. The Public Service Identity (PSI) defined in 3GPP standard (3rd Generation Partnership Project) is used to allow terminal clients to allocate this IW service. When sending the SIP (Session Initial Protocol) request out for multimedia services, the terminal includes the recipient’s address in the payload instead of the “Request-URI” header. In the network, the proposed solution provides the mapping rules between different networks in MM-IW (Multimedia IW). The detailed technical description and the corresponding use cases are present. The comparison with other alternatives is made. The benefits of the proposed solution are highlighted.

  4. Twenty-first century learning in afterschool.

    Schwarz, Eric; Stolow, David

    2006-01-01

    Twenty-first century skills increasingly represent the ticket to the middle class. Yet, the authors argue, in-school learning is simply not enough to help students develop these skills. The authors make the case that after-school (or out-of-school) learning programs are emerging as one of the nation's most promising strategies for preparing young people for the workforce and civic life. Most school systems have significant limitations for teaching twenty-first century skills. They have the limits of time: with only six hours per day there is barely enough time to teach even the basic skills, especially for those students starting already behind. They have the limits of structure: typical school buildings and classrooms are not physically set up for innovative learning. They have the limits of inertia and bureaucracy: school systems are notoriously resistant to change. And perhaps most important, they have the limits of priorities: especially with the onset of the No Child Left Behind Act, schools are laserlike in their focus on teaching the basics and therefore have less incentive to incorporate twenty-first century skills. Meanwhile, the authors argue that after-school programs are an untapped resource with three competitive advantages. First, they enable students to work collaboratively in small groups, a setup on which the modern economy will increasingly rely. Second, they are well suited to project-based learning and the development of mastery. Third, they allow students to learn in the real-world contexts that make sense. Yet the after-school sector is fraught with challenges. It lacks focus-Is it child care, public safety, homework tutoring? And it lacks rigorous results. The authors argue that the teaching of twenty-first century skills should become the new organizing principle for afterschool that will propel the field forward and more effectively bridge in-school and out-of-school learning.

    Full Text Available An essential element in a learning object repository is the meta-information associated with the resources housed by the repository, as this is what enables the objects to be retrieved. In many cases, the meta-information which is described consists of the classification of a resource in relation to a taxonomy or thesaurus. Agrega is a network of learning object repositories in which an LOM profile, called LOM-ES, has been used to label the objects. Part of the meta-information described corresponds to the classification of the object with respect to a group of taxonomies and a thesaurus, which have had to be described using the ims vdex standard to enable them to be managed from the federation nodes. This article describes the way in which ims vdex has been used in order to create this description and how these metadata instances are managed.

    The research project was started with the objective of developing the essential geological-technical-technological parts of the utilisation of highly-mineralised thermal waters for heating. It is based on the findings from the drilling and testing of 29 deep geothermal wells, the erection and operation of Geothermal Heating Stations in Northeast Germany until 1990. The operation of the Waren (Mueritz) and Neubrandenburg Geothermal Heating Stations including their modernisation and the solution of problems which occurred sometimes give proof of the principal technical-technological implementability of thermal water utilisation for energetic purposes. Matter of concern is the recirculation of the thermal water after being used for balneological purposes to the main flow of water used for energetic purposes without affecting subsequent reinjection. The conditioning of the thermal water before and after use for bathing and balneo-therapeutic purposes is another problrm. The essential results are presented here. (orig.)

    The industry-led, international intelligent manufacturing systems (IMS) program provides a special vehicle for joint research and development between government, industry and academia in the United States, Canada, Japan, Australia, and Europe. Since its beginning in 1989, the IMS program has progressed through a feasibility phase which demonstrated that international legal barriers, trade issues, and intellectual property problems could be overcome. The program is constructed to provide higher quality design, customized products, shorter delivery cycles and lower costs. Interactions between partner companies have led to new business opportunities for mutual profit and some claim to have learned strategic information about their international competitors. The IMS program is growing through the participation of hundreds of corporate and university partners who share responsibilities in specific projects and jointly reap benefits for their manufacturing products and processes. The logic for choosing or not choosing the IMS mechanisms will be discussed and R and D projects will be identified.

Aber auch gesellschaftlich konsensfaehige Loesungen und die Beachtung politischer Wuensche stellen den Wasserbauingenieur vor grosse planerische Herausforderungen. Ein Ziel des Symposiums ist es, an konkreten Beispielen Planung und Wirklichkeit vorzustellen, eventuelle Abweichungen zu diskutieren und Ursachen hierfuer herauszuarbeiten. (orig.)

    @@ Having a time machine like the cute Japanese cartoon character Doraemon was once a dream shared by many Chinese born in the 1980s and 1990s. Now a message posted at Tianya forum, one of the most popular of China's online communities, provides them with a virtual version. A seemingly meaningless post in May 2008, saying "I'm going back to 1997, and I will miss you guys and will not fail you in your trust," regained popularity at the end of 2009. By December 28, it had attracted more than 1.6 million visits and nearly 19,000 replies.

  14. Entscheidungsthematik im Rahmen der Onlineberatung

    Directory of Open Access Journals (Sweden)

    Josef Lang

    2011-10-01

    Full Text Available OnlineberaterInnen werden regelmäßig von Ratsuchenden angefragt, ihnen in Konfliktsituationen bei der Entscheidungssuche beizustehen. Die Erleichterung über eine relativ leicht verstehbare Fragestellung kann in Ratlosigkeit umschlagen, wenn sich hinter den einfach gekleideten Entscheidungsfragen untergründige Ambivalenzen des Klienten auftun. Auch selbst bei Entscheidungsfragen vom Format des Alltags wird die Aufgabe der Beraterin nicht immer leicht. Es soll durch die 'richtigen' Fragen ein Prozess gefördert werden, dessen Richtung vom Ratsuchenden festgelegt, nicht vom Berater gesteuert wird. Es ist die Rede von Prozessen, die allgegenwärtig sind, sie werden in der Welt der Bakterien beobachtet und in Hirnprozessen des Menschen gemessen und abgebildet werden. Wie die Hilfestellung in der Sprache der schriftlichen Kommunikation via Internet aussehen kann, zeigt der Artikel an Beispielen und mit einer Liste möglicher Strategien und Methoden exemplarisch auf. Ergebnisse der Entscheidungsforschung scheinen dem Autor nur teilweise für die Beratungspraxis hilfreich zu sein. Die Kenntnis der dort entwickelten Hilfen und Einsichten wird jedoch dazu beitragen, Fehler im Beratungsprozess zu verringern. Der Artikel reflektiert die Gewichtung von rationalen und emotionalen Anteilen bei der Entscheidungssuche im Blick auf Strömungen unserer Zeit und eingegrenzt auf eine westliche Kultur.

    Rappuoli, Rino

    2011-01-01

    In the twentieth century, vaccination has been possibly the greatest revolution in health. Together with hygiene and antibiotics, vaccination led to the elimination of many childhood infectious diseases and contributed to the increase in disability-free life expectancy that in Western societies rose from 50 to 78–85 years (Crimmins, E. M. & Finch, C. E. 2006 Proc. Natl Acad. Sci. USA 103, 498–503; Kirkwood, T. B. 2008 Nat. Med 10, 1177–1185). In the twenty-first century, vaccination will be expected to eliminate the remaining childhood infectious diseases, such as meningococcal meningitis, respiratory syncytial virus, group A streptococcus, and will address the health challenges of this century such as those associated with ageing, antibiotic resistance, emerging infectious diseases and poverty. However, for this to happen, we need to increase the public trust in vaccination so that vaccines can be perceived as the best insurance against most diseases across all ages. PMID:21893537

    The prerequisites for specific research into the use of Hot Dry Rock geothermal energy at great depths and temperatures of up to 147 C. In Europe were created with the drilling and completition of the 3334 m deep research drill hole Urach 3 in its phase I (1977/78), and its subsequent extension to 3488 m in phase II (1982/83) within the metamorphic gneiss rock of Urach. A single hole circulation system was tested. Basic results concerning the temperature field, joint system, stress field and hydraulic behavior of the rock were achieved. According to the European HDR guidelines data from depths were a mean reservoir temperature of 175-180 C prevails were necessary to carry out a HDR pilot project. Within the scope of a feasibility study the already existing drill hole Urach 3 was extended from 3488 m to 4445 m depth where the required rock temperature of >170 C was expected. The objective of the project was to determine rock parameters at depth of high temperatures. The bottom hole temperature at true vertical depth of 4394.72 m was determined with 170 C. It can be proved that the temperature gradient is constant with 2.9 K/100 m depth. Due to the results of the investigations it is proposed that the Urach site located in a widespread tectonic horizontal strike-slip system is suitable for a HDR demonstration project. The results can be applied in south German and northern Swiss regions and in other large regions of Europe. Many potential consumers of geothermal energy produced by the HDR concept are situated close around the Urach 3 drill site.

    A high-throughput approach and platform using 15 minute reversed-phase capillary liquid chromatography (RPLC) separations in conjunction with ion mobility spectrometry-mass spectrometry (IMS-MS) measurements was evaluated for the rapid analysis of complex proteomics samples. To test the separation quality of the short LC gradient, a sample was prepared by spiking twenty reference peptides at varying concentrations from 1 ng/mL to 10 µg/mL into a tryptic digest of mouse blood plasma and analyzed with both a LC-Linear Ion Trap Fourier Transform (FT) MS and LC-IMS-TOF MS. The LC-FT MS detected thirteen out of the twenty spiked peptides that had concentrations ≥100 ng/mL. In contrast, the drift time selected mass spectra from the LC-IMS-TOF MS analyses yielded identifications for nineteen of the twenty peptides with all spiking level present. The greater dynamic range of the LC-IMS-TOF MS system could be attributed to two factors. First, the LC-IMS-TOF MS system enabled drift time separation of the low concentration spiked peptides from the high concentration mouse peptide matrix components, reducing signal interference and background, and allowing species to be resolved that would otherwise be obscured by other components. Second, the automatic gain control (AGC) in the linear ion trap of the hybrid FT MS instrument limits the number of ions that are accumulated to reduce space charge effects, but in turn limits the achievable dynamic range compared to the TOF detector.

    According to its proponents, the Intelligent Manufacturing System is a highly efficient, global production system, designed as the first decisive step in ensuring that society will continue to flourish materially and spiritually. It is the gateway to advanced manufacturing and processing technologies, represented by a project-based, industry-led, government-endorsed program of cooperative research, carried out in seven industrially advanced regions of the world (Australia, Canada, Europe, Japan, Switzerland, USA, Korea). Currently, there are projects worth about $250 million in progress involving 200+ companies and 200+ research institutions. The benefits of IMS sponsorship, and the type of projects carried on as part of the program (e.g. projects dealing with total product life cycle issues, process issues, strategy/planning /design tools, human/organisation/social issues, virtual/extended enterprise issues) are discussed.

    Solar thermal electricity generation comprises a set of technologies which convert sunlight into electricity typically based on a thermal process. The main technologies in this assessment are parabolic trough systems, solar tower systems and dish-sterling systems. There are very good medium- to long-term prospects for solar thermal electricity production in terms of global market potential as well as technological development. Within the portfolio of renewable technologies, solar thermal electricity is expected to gain significant shares over the next decades. Germany has a very good starting position in terms of technological leadership and global market shares. In particular the strong position of German players in this field is supported by many years of experience in the development and production of key components of solar thermal power plants, which is aided by strong public R and D and a good market position in related technological areas, e.g. glass mirrors for the car industry. In order to maintain this position in the future, increased efforts are needed, especially in activating synergies in the innovation system by integrating additional key agents. Since Germany does not possess a home market for this technology, it is not possible to exploit domestic user-producer interactions. Therefore the main future challenge lies in the realisation of an entire project by a German consortium, which must include strong project developers who are able to accept the financial and technical risks and to fulfil turn-key contracts for such projects. From the European perspective, solar thermal electricity generation offers very good prospects in terms of industrial policy since Spain and Germany can be considered global leaders in this field. Spain can benefit from its recent experience in developing large-scale projects and from recent mergers and acquisitions of key technology producers in this field. If the current European efforts are maintained, solar thermal

    Full Text Available Das Waldviertel ist eine strukturschwache Region im Norden Österreichs, die eine innere Peripherie und innere Kolonie des österreichischen und europäischen Kapitalismus darstellt. Dieser Artikel analysiert die politische Ökonomie des Internets im Waldviertel. Das Waldviertel ist konfrontiert mit hohen Ausbeutungsraten im Rahmen einer imperialistischen Arbeitsteilung, Werttransfer, ungleichem Tausch, Niedriglöhnen, der Abwanderung der Textilindustrie, hoher Arbeitslosigkeit, Landflucht, dem Abbau öffentlicher Infrastruktur und Bevölkerungsrückgang. Die Analyse verdeutlicht, dass die Situation des Waldviertels als innere Peripherie der kapitalistischen Zentren die Kommunikationsverhältnisse prägt. Der Zugang zu Computern, dem Internet und Breitband ist im Waldviertel schlechter als in anderen Regionen, die Internet- und Mobiltelefonverbindungsgeschwindigkeit ist tendenziell langsamer und die Region ist eher unattraktiv für WissensarbeiterInnen. Es gibt im Waldviertel auch Ansätze einer Alternativökonomie, die den Imperialismus infrage stellen. Im Bereich der Informationsökonomie bestehen Potenziale für die Gründung von sozialistischen Kooperativen im Bereich Hardware, Software und soziale Medien, die die kapitalistische Informationsgesellschaft infrage stellen und für Alternativen kämpfen.

Ausgangspunkt war die These, dass die geographische Entfernung Kolumbiens zu Deutschland und die damit einhergehenden fehlenden Möglichkeiten der Lernenden, ihr im Unterricht erworbenes Wissen zu kontextualisieren, sich erschwerend auf die Entwicklung interkultureller Kompetenzen auswirkt. Mit dem Ziel, diese Schwierigkeit zu kompensieren, wurden zunächst die spezifischen Bedürfnisse der Lernenden ermittelt und verschiedene Lehrbücher hinsichtlich ihrer Angebote auf diese Bedürfnisse evaluiert. Schließlich wird gezeigt, wie die Ergebnisse in die Unterrichtspraxis implementiert wurden.   This article present s the results of an Action Research study carried out between 2010 and 2012 at the Colombian Universidad de los Andes. Its starting point was the hypothesis that the geographical distance between Colombia and Germany makes it more difficult for the students to contextualize the knowledge acquired in class, therefore impeding the development of intercultural competences. In order to compensate for this lack of contextualization the investigators first established the students´ specific needs. Then they evaluated different textbooks with regard to what they are offering to respond to those needs. Finally, the article describes how the findings were implemented in the classroom.

    the field of solar cooling are German and Austrian firms and many research facilities are distributed in mid and south Europe. The big area of installed solar collectors in Germany and Austria is facilitating applications in these countries. And the regulation demanding mandatory installation of solar collectors in Spain on new buildings is fostering the regional development. Political strategies may target: - the funding of additional pilot projects and small serial applications to support readiness for production of products and application technology, - the information and qualification of those sectors necessary for large scale application, like air condition specialists and architects, - Information and motivation of pilot users. Solar Cooling should also be observed in the design of regulations concerning sustainable building and heating. (orig.)

    The effects of mining lakes used as water stores (Dreiweibern, Lohsa II, Burghammer) on the water quality of the Spree river catchment area was investigated. The focus was on the potential water quality problems caused by the water storage, not on the processes involved in water quality development in general. Both expert opinions and monitoring results, especially of the project 'Gewaesserguete in Tagebauseen der Lausitz (BTUC/LMBV), suggest that especially in low-water situations with reduced storage levels, both the lake water quality and the quality of the receiving watercourses 'Kleine Spree' and 'Spree' will deteriorate dramatically. In consequence, water management should not be based on water volumes alone, but the aspect of water quality must be considered as a key criterion as well. In project 5.1, water management of the LOHSA II system was investigated, including the establishment of forecasts of recirculation conditions from the LOHSA II storages system into the Kleine Spree and Spree as receiving watercourses.

  13. Projections of twenty-first century climate over Europe

    2009-02-01

    Full Text Available We present an assessment of climate change pro jections over the European region for the 21st century from the ensembles of CMIP3 global model experiments and PRUDENCE regional climate model experiments. The A2, A1B, and B1 IPCC emission scenarios are considered. A brief review is also presented of the literature available on future European climate pro jections. In all emission scenarios the European region shows maximum warming of up to several degrees C over the Mediterranean region in summer and over northeastern Europe in winter. The precipitation change signal shows a north-south dipolar structure, with increasing precipitation over Northern Europe and decreasing over southern Europe. This structure migrates northward from the winter to the summer and is tied to the north-south motion of an increasing anticyclonic circulation cell over the North Atlantic-European sector. Temperature interannual variability decreases in winter over central and northern Europe and increases in summer throughout Europe. Precipitation interannual variability shows a predominant increase, most pronounced in summer. The seasonal temperature anomaly probability density functions (PDFs show a shift and a widening and flattening in future climate conditions, especially in summer, which is indicative of pronounced increases of extreme hot seasons. The seasonal precipitation anomaly PDFs show pronounced changes over Southern Europe in summer, with a strong increase of very dry seasons. In general, the magnitude of future climate change increases with the greenhouse gas forcing. A broad consensus is found between the pro jections obtained with the CMIP3 and PRUDENCE ensembles, as well as between the present analysis and previous generations of model pro jections. The climate change signal over Europe exhibits a consistent latitudinal and seasonal evolution identified as the European Climate change Oscillation (ECO by Giorgi and Coppola [F. Giorgi and E. Coppola, Geophys. Res. Lett. 34, L21703 (2007]. The changes of temperature and precipitation over Europe are pronounced, making this region highly vulnerable to global warming.

    In its second phase the research campaign against ``forest death`` tries to work out useful knowledge as a basis for forest restoration and conducted several case studies in different damaged forest areas in Austria. By establishing and testing diagnose profiles in the case study areas as well as developing and application of suitable expert systems we hope to find a practice-related solution for the ``new`` forest damages. For reasons of differential diagnostics we include existing pollution as well as acute causes of damage (eg. forest pasture, game bite etc.). We here introduce the Loisachtal (Tyrol) case study as it is fairly close to the area of the Wank-project. (orig./EW) [Deutsch] Die Forschungsinitiative gegen das ``Waldsterben`` versucht gegenwaertig in ihrer 2. Projektphase anhand mehrerer, gestaffelt ablaufender Fallstudien in verschiedenen Waldschadensgebieten Oesterreichs, geeignete Grundlagen fuer entsprechende Waldsanierungskonzepte zusammenzutragen. Durch die Herleitung und Test von Diagnoseprofilen in den Fallstudiengebieten und die Entwicklung und Anwendung von einschlaegigen Expertensystemen sollen praxisnaehere Antworten auf die ``neuartigen Waldschaeden`` gefunden werden. Das schliesst aus differentialdiagnostischen Gruenden auch die Einbeziehung von Altlasten und akuten Schadursachen (z.B. Waldweide, Wildverbiss) mit ein. Die Fallstudie Loisachtal (Tirol) wird aufgrund ihrer raeumlichen Naehe zum Wank-Projekt hier etwas eingehender in ihrer Konzeptionierung vorgestellt. (orig.)

RadIMS has been designed to fulfill all the requirements of US Department of Energy (USDOE) Order 5480.11, Radiation Protection for Occupational Workers.'' This Order requires the contractor to maintain detailed radiation exposure records on all individuals who work at the facility. These records must be retrievable for the entire working life of the individual and be available to other USDOE contractors on request. To meet these general needs, RadIMS provides for retrieval of detailed, comprehensive individual exposure histories as well as the usual online interactions to accomplish day-today radiation protection operations. These two extremes of functionality require different approaches in the WINCO computing environment. The exposure histories include database text, paper, microfilm, and electronic bitmaps.

    Conventional projection radiography (chest x-ray) is one of the most frequently requested procedures in radiology. Even though chest x-ray imaging is frequently performed in asymptomatic patients for preoperative assessment, clinically relevant incidental findings are relatively scarce. This is due to the relatively low sensitivity of chest x-rays where few clinically relevant incidental findings are to be expected, as any detectable pathologies will as a rule already be clinically symptomatic. Recommendations from relevant societies for the management of incidental findings, apart from the clarification of incidental nodules, do not exist. This review article therefore describes the most frequent and typical incidental findings of lung parenchyma (apart from pulmonary nodules), mediastinal structures including the hilum of the lungs, pleura, chest wall and major vessels. Also described are those findings which can be diagnosed with sufficient certainty from chest x-rays so that further clarification is not necessary and those which must be further clarified by multislice imaging procedures or other techniques. (orig.) [German] Eine der haeufigsten Untersuchungen in der Radiologie ist die konventionelle Projektionsradiographie des Thorax (Roentgenthorax). Auch wenn projektionsradiographische Aufnahmen im Rahmen einer praeoperativen Abklaerung haeufig als orientierende Untersuchung angefertigt werden, sind - bedingt durch die relativ geringe Sensitivitaet des Roentgenthorax - wenig klinisch relevante Zufallsbefunde zu erwarten, da nachweisbare Pathologien in der Regel bereits auch klinisch apparent sind. Empfehlungen entsprechender Fachgesellschaften zu Zufallsbefunden im Roentgenthorax jenseits der Abklaerung von Rundherden liegen nicht vor. Die vorliegende Arbeit beleuchtet daher haeufige und typische Zufallsbefunde des Lungenparenchyms (ausser den Lungenrundherden), der mediastinalen Strukturen einschliesslich der Hili, der Pleura, der Thoraxwand sowie der

    The purpose of the present cooperative research project is to study the toxicity, the degradation and in particular the dispersion behaviour of biologically rapidly degradable hydraulic oils and rape oil methyl esters (RME) in soils and waters with a special focus on hydraulic oils. This is to serve as a basis for developing guidelines for action in the event of accidents involving biologically rapidly degradable hydraulic fluids that ensure proper accident reporting and handling. The outcome of the cooperative research project is to permit a first risk assessment for the soil and water compartments in the event of accidents involving hydraulic oils and RME. Another task is to clarify to what extent it is permissible to deviate from the usual measures prescribed for oil accidents involving crude oil when biologically rapidly degradable hydraulic oils or RME are involved instead. [German] Ziel des Verbundvorhabens ist es, die Toxizitaet, den Abbau und insbesondere das Ausbreitungsverhalten von biologisch schnell abbaubaren Hydraulikoelen und Rapsoelmethylester (RME) in Boden und Wasser zu untersuchen, wobei der Schwerpunkt der Arbeiten bei den Hydraulikoelen liegt. Damit sollen Verfahrensrichtlinien angegeben werden, die im Falle von Unfaellen mit biologisch schnell abbaubaren Hydraulikfluessigkeiten oder Biodiesel eine angemessene Unfallaufnahme und -abwicklung sicherstellen. Als Ergebnis des Verbundvorhabens soll eine erste Risikoabschaetzung fuer die Kompartimente Boden und Wasser bei Unfaellen mit Hydraulikoelen und RME moeglich sein. Darueber hinaus soll geklaert werden, inwieweit Abweichungen von den ueblichen Massnahmen bei Oelunfaellen mit Mineraloelprodukten im Vergleich zu biologisch schnell abbaubaren Hydraulikoelen oder RME moeglich sind.

  2. IMS-MS and IMS-IMS investigation of the structure and stability of dimethylamine-sulfuric acid nanoclusters.

    Recent studies of new particle formation events in the atmosphere suggest that nanoclusters (i.e, the species formed during the early stages of particle growth which are composed of 10(1)-10(3) molecules) may consist of amines and sulfuric acid. The physicochemical properties of sub-10 nm amine-sulfuric acid clusters are hence of interest. In this work, we measure the density, thermostability, and extent of water uptake of dimethylamine-sulfuric (DMAS) nanoclusters in the gas phase, produced via positive electrospray ionization. Specifically, we employ three systems to investigate DMAS properties: ion mobility spectrometry (IMS, with a parallel-plate differential mobility analyzer) is coupled with mass spectrometry to measure masses and collision cross sections for dimethylamine to sulfuric acid originally present in the electrospray solution. IMS-IMS thermostability studies reveal that partial pressures of DMAS nanoclusters are dependent upon the electrospray solution concentration ratio, R = [H2SO4]/[(CH3)2NH]. Extrapolating measurements, we estimate that dry DMAS nanoclusters have surface vapor pressures of order 10(-4) Pa near 300 K, with the surface vapor pressure increasing with increasing values of R through most of the probed concentration range. This suggests that nanocluster surface vapor pressures are substantially enhanced by capillarity effects (the Kelvin effect). Meanwhile, IMS-IMS water uptake measurements show clearly that DMAS nanoclusters uptake water at relative humidities beyond 10% near 300 K, and that larger clusters uptake water to a larger extent. In total, our results suggest that dry DMAS nanoclusters (in the 5-8.5 nm size range in diameter) would not be stable under ambient conditions; however, DMAS nanoclusters would likely be hydrated in the ambient (in some cases above 20% water by mass), which could serve to reduce surface vapor pressures and stabilize them from dissociation.

    1998-06-01

    The role of wind power in the industrial sector currently depends very much on its technical and economic integrability in existing conventional supply structures. The most important questions in this context relate to capacity effects, adapted operating methods of conventional power suppliers, and, most important of all, operational energy production costs. In some regions alternative energy supply concepts are not yet or not sufficiently available. However, these will nevertheless offer ways of installing energy systems with a large renewable segment. The chances of bringing such projects to fruition depend for one thing on the climate, which may either stimulate or deter from development work on renewables (wind power, solar energy), and for another, often in apparent opposition to the former, on the oftentimes poorly developed infrastructure and economic strength of the region in question. [Deutsch] Die Bedeutung der Windenergienutzung im industrialisierten Bereich ist derzeit verknuepft mit deren technischen und oekonomischen Integrationsfaehigkeit in bestehende, konventionelle Versorgungsstrukturen. Im Vordergrund steht hierbei die Klaerung der Fragestellungen nach Kapazitaetseffekten, angepassten Betriebsweisen konventioneller Stromerzeuger und, in erster Linie, betriebswirtschaftlichen Energieerzeugungskosten. Derzeit bieten die Regionen, in denen eine anderweitige Versorgung noch nicht oder in nicht ausreichendem Masse existieren Moeglichkeiten zur Installation von Energiesystemen mit hoher regenerativer Durchdringung. Fuer die Realisation solcher Projekte stehen sich haeufig die klimatischen Bedingungen, die einerseits z.T. die Ursache fuer den geringen Entwicklungsstand sind, andererseits aber auch guenstige Voraussetzungen fuer die Nutzung regenerativer Energien (Wind, Sonne) bieten, der meist schlechten Infrastruktur und der geringen Wirtschaftskraft gegenueber.

Methods:The results of the management for 76 patients with closed extra-articular distal tibia fracture by intramedullary nailing and plating were reviewed retrospectively.The variables included AO (Arbeitsgemeinschaft fur Osteosynthesefragenclassification of tibia fracture, the mean duration of union, malunion,and nonunion.   Results: Twenty seven and forty nine patients were treated by intramedullary(IM nailing and plating respectively.The most common type of fractures was A1 which was observed in twenty five patients. Initial union and nonunion occurred in   sixty three and thirteen patients respectively. Eight patients had nonunion in plating   group and five of twenty seven patients in IM nailing group. Eleven of twenty seven patients in IM nailing group suffered from malunion while only four patients in the other group had this complication.   Conclusion: The plating Technique in comparison with IM nailing has a satisfactory functional outcome.The technique has a lower incidence of malunion and nonunion, and it should be recommended as a good treatment option for the management of extra-articular closed fracture of distal tibia.

    但是,当前的移民搬迁工作还存在着一些问题。以陕南地区避灾移民搬迁工程为例,搬迁过程中出现普遍的“搬富不搬穷”现象,一定程度上背离了移民搬迁设计的“挖险根”和“挖穷根”的目标和宗旨。这种偏离不仅对普通农户和贫困家庭的生产生活产生消极影响,还蕴藏着区域性社会风险,因此政府应当转变观念,在移民搬迁过程中引入市场机制,通过购买保险服务的方式,有效化解移民搬迁过程中出现的突出问题,为移民搬迁工程的顺利推进保驾护航,也为其他地区政府提供推进移民搬迁工作的有益借鉴。%In recent years, local governments in the migration work is had a great idea , spent a great effort , has made no small achievement .But the current migration work still exist some problems .In southern Shaanxi im-migrants to avoid disaster in the relocation project as an example , the common appeared in the process of relocation"move rich don't move poor"phenomenon , to some extent , deviated from the migration design "dig risks root"and"dig poor root"goals and objectives .This deviation is not only the production life of ordinary farmers and poor fam-ilies have a negative impact , also contain the regional social risk , so the government should change concept , intro-ducing market mechanism , in the process of migration through the way of buying insurance services , effectively re-solve the problems appeared in the course of migration , the escort for immigrant relocation project smoothly , also for other areas to proceed with the migration of beneficial references for the government .

    Full Text Available Dieser Artikel zeigt anhand von Beispielen auf, dass die Theorien des Symbolischen Interaktionismus an Aktualität nichts eingebüßt haben, obwohl es aufgrund von digitalen Medien einen einschneidenden gesellschaftlichen Wandel vor allem in der Art und Weise, wie Kommunikation und soziale Interaktionen betrieben werden, gegeben hat. Es wird versucht die Theorien des Symbolischen Interaktionismus in Verbindung mit dem Gebrauch von digitalen Medien, insbesondere dem Smartphone darzustellen. Obwohl es in den letzten 80 Jahren maßgebliche Veränderungen in der Gesellschaftsordnung und im Bildungswesen gegeben hat, kann nachvollzogen werden, dass diese Theorien auf die Interaktionen im täglichen Leben nach wie vor angewendet werden können. So aktuell die Theorien sind, können sie aber nicht die Frage beantworten, wie schnell sich eine konkrete Unterrichtspraxis auf die sich rasch ändernden Funktionen der digitalen Medien einstellen soll.

    Full Text Available Convergence of technologies is important in this era to make progress in any field. The need to converge technologies arises from the concept of improvisation. This paper proposes a system architecture which is used to diagnose vehicle parameters and then relay the data via a feasible next generation network based on IMS architecture to a central server. Vehicles are to be equipped with a simple portable scan tool (PST device which will interface with the OBD-II port of the vehicle and record the diagnostic data and relay them to the server. Further if the vehicle owner wants real time remote updates of the vehicle then it can be done by using his/her cellular device. IMS architecture simplifies the process of user registration and help in achieving faster transmission speed. Lastly various secondary applications can be generated by this system as by using thissystem the vehicles are getting connected on a grid.

    Turbulence Heating ObserveR (THOR) is the first mission ever flown in space dedicated to plasma turbulence. Specifically, THOR will study how turbulent fluctuations at kinetic scales heat and accelerate particles in different turbulent environments within the near-Earth space. To achieve this goal, THOR payload is being designed to measure electromagnetic fields and particle distribution functions with unprecedented resolution and accuracy. Here we present the Ion Mass Spectrometer (IMS) instrument that will measure the full three-dimensional distribution functions of near-Earth main ion species (H+, He+, He++ and O+) at high time resolution (~ 150 ms for H+ , ~ 300 ms for He++) with energy resolution down to ~ 10% in the range 10 eV/q to 30 keV/q and angular resolution ~ 10°. Such high time resolution is achieved by mounting multiple sensors around the spacecraft body, in similar fashion to the MMS/FPI instrument. Each sensor combines a top-hat electrostatic analyzer with deflectors at the entrance together with a time-of-flight section to perform mass selection. IMS electronics includes a fast sweeping high voltage board that is required to make measurements at high cadence. Ion detection includes Micro Channel Plates (MCP) combined with Application-Specific Integrated Circuits (ASICs) for charge amplification, discrimination and time-to-digital conversion (TDC). IMS is being designed to address many of THOR science requirements, in particular ion heating and acceleration by turbulent fluctuations in foreshock, shock and magnetosheath regions. The IMS instrument is being designed and will be built by an international consortium of scientific institutes with main hardware contributions from France, USA, Japan and Germany.

    To automate astronaut organ and effective dose calculations from occupational X-ray and computed tomography (CT) examinations incorporating PCXMC and ImPACT tools and to estimate the associated lifetime cancer risk per the National Council on Radiation Protection & Measurements (NCRP) using MATLAB(R). Methods: NASA follows guidance from the NCRP on its operational radiation safety program for astronauts. NCRP Report 142 recommends that astronauts be informed of the cancer risks from reported exposures to ionizing radiation from medical imaging. MATLAB(R) code was written to retrieve exam parameters for medical imaging procedures from a NASA database, calculate associated dose and risk, and return results to the database, using the Microsoft .NET Framework. This code interfaces with the PCXMC executable and emulates the ImPACT Excel spreadsheet to calculate organ doses from X-rays and CTs, respectively, eliminating the need to utilize the PCXMC graphical user interface (except for a few special cases) and the ImPACT spreadsheet. Results: Using MATLAB(R) code to interface with PCXMC and replicate ImPACT dose calculation allowed for rapid evaluation of multiple medical imaging exams. The user inputs the exam parameter data into the database and runs the code. Based on the imaging modality and input parameters, the organ doses are calculated. Output files are created for record, and organ doses, effective dose, and cancer risks associated with each exam are written to the database. Annual and post-flight exposure reports, which are used by the flight surgeon to brief the astronaut, are generated from the database. Conclusions: Automating PCXMC and ImPACT for evaluation of NASA astronaut medical imaging radiation procedures allowed for a traceable and rapid method for tracking projected cancer risks associated with over 12,000 exposures. This code will be used to evaluate future medical radiation exposures, and can easily be modified to accommodate changes to the risk

    Full Text Available Gemeinsam von Künstlern und Wissenschaftlern/Philosophen erstellte Bücher sind selten und nicht immer erfolgreich. Eines der Fährnisse ist das Verhältnis zwischen bildlichen und schriftlichen Anteilen: Nicht selten wird der künstlerische Anteil zur Illustration der dominierenden Schrift. Eine Neupositionierung des Bildes im Buch ist nun der amerikanischen Künstlerin Roni Horn gelungen. Mehr als „sujet“ ihres Buches, ist die französische Philosophin Hélène Cixous gleichsam instruierende „Stimme“, die im Bild aufscheint. Horn hat dadurch zugleich – einmal mehr – das Phantasma unmittelbarer Abbildhaftigkeit des Fotos dekonstruiert und der philosophischen Position Cixous‘ durch das Bild eine Dimension hinzugefügt.Books created through a combined effort between artists and scholars occur seldom and are not always successful. A particular imbalance is found in the relationship between image and text: often the visual components serve merely to illustrate the more dominant text. The American artist Roni Horn has finally repositioned the importance of images in books. The voice of French philosopher Hélène Cixous is not merely the “sujet” of Horn’s book, but her instructive voice appears simultaneously in “image.” Horn thus both deconstructs the chimera of the photo’s ability to immediately visually depict the real and also adds a new dimension to Cixous’ philosophic position with her images.

Der Webseite liegt die Motivation zugrunde, Schülerinnen und Schüler für ein Nachdenken über globale Themen zu sensibilisieren. Ein solches Nachdenken ist immer auch eines über bildlich vermittelte Wirklichkeit. Es ist mit bildbild ein Anliegen, angesichts einer allseits konstatierten «Bilderflut» ein didaktisches Medium zu entwickeln, das einen Fundus an historischen und aktuellen Fotografien zur Verfügung stellt und diese so aufbereitet, dass sie gerade nicht hinter ihrer illustrativen Funktion verschwinden. Dadurch sollen die Bilder für ein selbständiges Lernen auf dem Weg hin zu einer visuellen Kompetenz einsetzbar gemacht werden. Der Beitrag beleuchtet die Entwicklung der Webseite vor dem Hintergrund kulturkritischer Haltungen zum Bild seit der Moderne sowie im Rahmen dessen, was seit den 1970er Jahren im pädagogischen Kontext als Visual Literacy diskutiert und gefördert wird. Dabei wird auch auf die medialen Potenziale einer Webseite für die Bildlesekompetenz von Jugendlichen eingegangen.

    Full Text Available We present the analysis of twenty human genomes to evaluate the prospects for identifying rare functional variants that contribute to a phenotype of interest. We sequenced at high coverage ten "case" genomes from individuals with severe hemophilia A and ten "control" genomes. We summarize the number of genetic variants emerging from a study of this magnitude, and provide a proof of concept for the identification of rare and highly-penetrant functional variants by confirming that the cause of hemophilia A is easily recognizable in this data set. We also show that the number of novel single nucleotide variants (SNVs discovered per genome seems to stabilize at about 144,000 new variants per genome, after the first 15 individuals have been sequenced. Finally, we find that, on average, each genome carries 165 homozygous protein-truncating or stop loss variants in genes representing a diverse set of pathways.

    Full Text Available Die Medienfront ist heute ein wichtiger Kriegsschauplatz, den viele neben Land, Wasser und Luft für gleich wichtig halten. Terroristen fühlen sich in sozialen Medien wohler als man denken könnte. Im Netz können sie die asymmetrische Kräfteverteilung überwinden, die sie in der offenen Feldschlacht unterlegen sein ließe. Terroristen machen sich das Bild zur Waffe und produzieren erst durch die Positionierung an der Medienfront Sinn in ihren Taten. Ohne ein Bekennerschreiben, ein Abschiedsvideo des Attentäters oder ein letztes Posting im sozialen Netzwerk wäre ein Bombenanschlag nichts als ein Kapitalverbrechen. Durch die terroristische Kommunikationsstrategie wird das Verbrechen erst zum terroristischen Akt. Das ist die theoretische Grundannahme dieses Aufsatzes. Ohne Medienberichterstattung könnten terroristische Organisationen nicht existieren. Durch die Entwicklung des Web 2.0 und insbesondere sozialer Medien kommen terroristische Organisationen heutzutage aber ganz ohne das Verschicken von Videotapes an Fernsehsender aus. Durch YouTube und andere Kanäle, können sie die Adressaten ihrer Botschaften direkt und ohne zwischengeschaltete Journalistinnen und Journalisten erreichen. So ist es nicht erstaunlich, dass terroristische Organisationen sich eine gewisse Expertise im Umgang mit sozialen Medien zugelegt haben. Al-Qaida hat seine eigene Medienabteilung, auch die kolumbianischen FARC arbeiten sehr professionell und welchen Einfluss der Islamische Staat im Internet ausübt ist inzwischen bereits Gegenstand einiger Reportagen und Untersuchungen geworden. Die diesem Aufsatz zugrundeliegende Arbeit hat sich mit neun verschiedenen Videos aus dem Umfeld von al-Qaida, der IRA und der FARC beschäftigt und versucht, aus dem analytischen Vergleich dieser Videos Rückschlüsse über terroristische Medienmacher und die terroristischen Organisationen selbst zu ziehen.

We propose a two-dimensional tree-based taxonomy of IMS resilience challenges. This taxonomy considers unique features of IMS such as the layered architecture. We also classify the existing countermeasures into eight classes. We identify the resilience objectives of these countermeasures and analyze their applicability and efficiency on challenge families.

    Full Text Available Die Pluralbildung im Deutschen ist nicht chaotisch, aber komplex. Unabhängig davon, ob man für die Pluralbildung Regeln, Schemata oder die Wortstruktur als Erklärungsmodell benutzt, bleibt die Tatsache einer beachtlichen Zahl miteinander konkurrierender Formen zu erklären. Dies gilt schon deshalb, weil die Variation unter den Pluralformen wohl mit dazu beiträgt, dass trotz der Arbeiten von Mugdan 1977 und Köpcke 1987, 1993, der klaren Darstellung des Pluralsystems in vielen Grammatiken, z.B. Eisenberg 1986, 1989, 1998 noch immer bisweilen die Meinung besteht, die Pluralbildung im Deutschen sei arbiträr.Es soll gezeigt werden, dass das Pluralsystem des Deutschen nach Beschränkungen aufgebaut ist, die morphologischer und silbenphonologischer Natur sind und sich im Rahmen der Optimalitätstheorie (OT beschreiben lassen. Die OT nimmt an, dass Wortformen universalen Beschränkungen (Constraints unterliegen, und dass diese prinzipiell verletzbar sind. Ich werde zunächst die für die Pluralbildung relevanten Beschränkungen definieren, dann an heimischen Pluralformen und -varianten ihr Zusammenwirken zeigen und schließlich den Assimilationsprozess von Fremdwörtern mit Hilfe dieser Beschränkungen und der Beschränkungshierarchien zu erklären versuchen. Daran werden schließlich Überlegungen zu Verarbeitung und Lernbarkeit der Pluralformen geknüpft.

    The Bitterfeld ground water is contaminated with many different pollutants over a large area. Long-term measures like reactive barriers for purification are required. However, groundwater contaminated with multiple contaminants cannot be purified by a single reactive material; for this reason, the effectivity of combinations of different reactive materials was investigated. Of the combinations investigated, reducing iron and activated carbon connected in series was the most effective: The iron will remove the reducible chlorinated hydrocarbons, while the rest of the contaminants are adsorbed to the activated carbon. Iron and ORC was another interesting option, but the combination of iron and activated carbon was found to be the most favourable option. Until a better method is available, it is recommended to connect iron and activated carbon in parallel for removing contaminant mixtures. Directly behind reactive iron barriers (also when combined with activated carbon), the limiting values of the Freshwater Ordinance for Fe(II) and pH are exceeded. Directly behind ORC reactors, the limiting values for Mg and pH are exceeded. Investigations in the outflow of these reactive materials showed that the high pH values are buffered by contact with the aquifer material to values typical of aquifers, which usually are below the limiting values of the Freshwater Ordinance. However, as the buffer capacity of the soil is exhausted, a zone with a higher pH starts to grow in the aquifer. The growth of this zone depends on the pH and on the aquifer material. Especially in soils as found at Bitterfeld, with a high concentration of organic matter, we find long-term desorption of pollutants from the aquifer materials which will burden the purified water leaving the water treatment system and prohibit its utilization.

    This final entry in the History of Human Space Exploration mini-series by Ben Evans continues with an in-depth look at the latter part of the 20th century and the start of the new millennium. Picking up where Partnership in Space left off, the story commemorating the evolution of manned space exploration unfolds in further detail. More than fifty years after Yuri Gagarin’s pioneering journey into space, Evans extends his overview of how that momentous voyage continued through the decades which followed. The Twenty-first Century in Space, the sixth book in the series, explores how the fledgling partnership between the United States and Russia in the 1990s gradually bore fruit and laid the groundwork for today’s International Space Station. The narrative follows the convergence of the Shuttle and Mir programs, together with standalone missions, including servicing the Hubble Space Telescope, many of whose technical and human lessons enabled the first efforts to build the ISS in orbit.

    Full Text Available Since achieving statehood in 1991, Armenia has faced major economic and political obstacles which have significantly affected the nation’s research libraries. This research paper will quantitatively and qualitatively examine the challenges facing Armenian research libraries just over twenty years after the collapse of the Soviet Union. Specifically, the authors analyze their interviews with five library administrators at five major institutions, respectively. These include Yerevan State University Library, the National Library of Armenia, the Fundamental Scientific Library of the National Academy of Sciences of Armenia, the Republican Scientific-Medical Library of Armenia, and the Papazian Library of the American University of Armenia. The instrument for the interviews consists of 73 questions based on the 2004 Association of College and Research Libraries Standards for Libraries in Higher Education and evaluates the following factors:• The library’s mission, goals and objectives• Public or user services• Instruction activities at the library• Resources (print, media, or electronic and collection development• Access to the library’s resources• Outcome assessment, or evaluation of the library• Staffing issues• Facility maintenance and plans for library development• Communication and cooperation both within the library and with the user community• Administration• BudgetIn addition, we will focus on the strengths and weaknesses of these libraries and investigate the growing open access movement in Armenia. Based on our findings, the authors wish to facilitate dialogue and consider possible approaches to help these libraries meet Armenia’s pressing information needs.

    2013-01-01

    Over the past twenty years, the Cassini-Huygens Mission has successfully utilized systems engineering to develop and execute a challenging prime mission and two mission extensions. Systems engineering was not only essential in designing the mission, but as knowledge of the system was gained during cruise and science operations, it was critical in evolving operational strategies and processes. This paper discusses systems engineering successes, challenges, and lessons learned on the Cassini-Huygens Mission gathered from a thorough study of mission plans and developed scenarios, and interviews with key project leaders across its twenty-year history.

    Full Text Available Nachlässe rücken in der wissenschaftlichen Forschung immer mehr in den Fokus, wie etwa die stark gestiegenen Nutzerzahlen der Bayerischen Staatsbibliothek (BSB über die letzten Jahre hinweg deutlich zeigen. Umso wichtiger ist insbesondere für Bibliotheken mit umfangreichen und fachlich breit gestreuten Nachlassbeständen eine möglichst genaue Erschließung im Internet, um der wissenschaftlichen Forschung einen schnellen Zugriff auf diese unikalen Materialien zu ermöglichen. Bei der digitalen Bereitstellung und vernetzten Erschließung verfolgt die BSB mit ihren rund 1.100 Nachlässen eine doppelte Strategie. Einerseits wird versucht, ausgewählte Nachlässe im Verbundsystem Kalliope zu katalogisieren. Andererseits werden die Erschließungsdaten zu den bereits erschlossenen und den erst grob geordneten Nachlässen, die in Form von hand- oder maschinenschriftlichen Listen sowie als Wordlisten vorliegen, digitalisiert und über den Bibliothekskatalog online zur Verfügung gestellt, um den Nutzern die Möglichkeit zu geben, sich so über die vorhandenen Bestände zu informieren. Wie dieses Projekt genau durchgeführt wurde, ist Gegenstand des Artikels. Special collections and personal papers are becoming more and more important for academic research, as is shown clearly by the increasing usage numbers at the Bavarian State Library (BSB over the last couple of years. Especially for libraries with extensive and manifold collections of estates, it is important to present these unique materials in a well-indexed manner on the internet, in order to give the scientific community easy access. The Bavarian State Library, which keeps more than 1.100 estates of personal papers, pursues a double strategy: On the one hand, selected estates are fully cataloged in the database “Kalliope”. As this procedure is likely to take a long time, the library on the other hand has been digitizing older hand- or typewritten lists with information

    In 2005, after starting the revenue operation of the Transrapid Maglev train between Berlin and Hamburg with a train interval of 20 minutes, a new railway era will beginn in many respects. The noncontact levitation and propulsion system permits cruising speeds of more than 400 km/h and reduces the travel time between the cities to less than one hour. Due to the attractive city connection, flight connections will be unnecessary and the motorway will be relieved from many cars. Another feature of the project is the public private partnership and the engagement of the electricity supply companies. Compared to the previous co-operation between the electricity supply companies and the Deutsche Bahn AG (German railway) the engagement is much more intensive. (orig.) [Deutsch] Wenn im Jahr 2005 die Magnetschnellbahn Transrapid ihren Betrieb zwischen Berlin und Hamburg im 20-Minuten-Takt aufnimmt, beginnt in mehrfacher Hinsicht eine neue Aera im elektrischen Bahnverkehr. Die beruehrungsfreie Antriebs- und Schwebetechnik des Transrapid ermoeglicht Geschwindigkeiten ueber 400 km/h und verkuerzt so die Reisezeit zwischen den Staedten auf unter 1 h. So werden Flugverbindungen ueberfluessig, und die Autobahn wird aufgrund der attraktiven Bahnverbindung entlastet. Ein weiteres Novum des Projektes stellt die privatwirtschaftliche Beteiligung und die Einbindung der Stromversorger in das Projekt dar. Sie geht weit ueber die bisherige Zusammenarbeit mit der Deutschen Bahn hinaus. (orig.)

    Legal actions taken by associations are part of environmental law in Europe and North America. In most cases, action is taken to set aside administrative acts. Action taken to set aside planned projects or abstract regulations of a general nature are an exception. On the European continent, the jurisdiction lies with administrative courts; in anglo-American countries, with civil courts. Denmark has a special institution for internal evaluation of decisions made by administrative bodies. A right of appeal is granted in most countries. Few countries make special demands on the structure of the association taking action. As far as the right of action is concerned, most countries require that the legal interests of a natural person most have been violated. In the case of legal actions taken by an association, the rights of the association are considered to be equal to the rights of a natural person. Limitations as in German law are uncommon, although federal states tend to make a distinction between decisions on federal and state level. (orig./HSCH) [Deutsch] Die Untersuchung zeigt, dass die Verbandsklage im Umweltschutzrecht in unterschiedlichen Formen in Europa und in Nordamerika zu finden ist. Meistens ist sie als Anfechtungsklage gegen Verwaltungsakte konzipiert, nur in Ausnahmefaellen koennen Plaene oder abstrakt-generelle Regelungen angefochten werden. In den kontinentaleuropaeischen Laendern sind die Verwaltungsgerichte, in den anglo-amerikanischen Laendern die Zivilgerichte fuer die Verbandsklagen zustaendig. In Daenemark ist ein spezielles Organ zur verwaltungsinternen Ueberpruefung von Entscheidungen zustaendig. Berufungsmoeglichkeiten sind in den meisten Laendern vorhanden. Nur in wenigen Laendern werden besondere formelle Erfordernisse an den Verband gestellt. Die Klagebefugnis ist dergestalt geregelt, dass meistens rechtliche Interessen einer natuerlichen Person fuer die Klageerhebung verletzt sein muessen.

    Research into environmental factors and how they affect the health of children needs to address a number of questions: Does the environment play any part in this at all? What are the affecting environmental factors? What is the scope of specific environmental factors relative to an induction or an enhancement of a disease? The search for and identification of allergens has priority relative to allergic developments in children. The author describes major allergen sources, the pathogenesis of allergies, the analysis of allergens and a study conducted by several pediatric clinics on the development of allergies in infants and young children, while focussing on risk factor of house-dust mites and options to reduce the exposure to mite-associated allergens. (Uhe) [Deutsch] Bei der Erforschung von Umweltfaktoren und ihrem Einfluss auf die Gesundheit von Kindern interessieren mehrere Fragen: spielt die Umwelt ueberhaupt ein Rolle? Welche Umwelteinfluesse sind es, wie gross ist die krankheitsindzierende oder krankheitsverstaerkte Rolle bestimmter Umwelteinfluesse? Fuef die Allergieentwicklung bei Kindern stehen die Allergene an erster Stelle. Neben der Beschreibung der wichtigsten Allergiequellen und der Entstehung von Allergien und Analytik von Allergenen wird ausfuehrlich eine Studie verschiedener Kinderkliniken zur Allergieentwicklung im Kindesalter beschrieben. Dabei wird vor allem auf den Risikofaktor Hausstaubmilbe und die Moeglichkeiten der Reduzierung der Milbenallergenbelastung eingegangen. (Uhe)

    2009-01-01

    Full Text Available Epilepsie tritt beim älteren Menschen bis zu 3-mal häufiger auf als in jüngeren Jahren. Dadurch und bedingt durch die allgemeine Zunahme des älteren Bevölkerungsanteils wird die Altersepilepsie immer bedeutender. Die ätiologischen Faktoren umfassen in erster Linie zerebrovaskuläre Ereignisse, Traumen, Tumoren oder Demenzsyndrome. Zumeist treten in diesem Alter fokale Anfälle mit oder ohne sekundäre Generalisierung auf. Die klinische Symptomatik kann jedoch sehr diskret sein und differenzialdiagnostisch Schwierigkeiten in der Abgrenzung zu kardialen Synkopen oder transienten ischämischen Ereignissen bieten. Aufgrund von altersbedingten Änderungen in der Pharmakokinetik stellt die Behandlung der Altersepilepsie besondere Ansprüche an den behandelnden Arzt. Die Wahl des geeigneten Antiepileptikums richtet sich dabei nicht nur nach der durch Studien belegten Effektivität, sondern muss auch die individuelle Gesamtsituation (Komorbidität, Komedikation in die Entscheidung mit einbeziehen. Im Vergleich zu den "älteren" Antiepileptika sind neuere Substanzen zwar meist nicht wesentlich effektiver, jedoch oft besser verträglich und sollten daher in dieser Altersgruppe verstärkt eingesetzt werden.

Los criterios son puestos a prueba a través de la comparación de libros de Primaria de diferentes editoriales españolas, analizando cómo se trabaja la competencia visual en las actividades de las unidades didácticas sobre el cuerpo humano. Algunos de los criterios estudiados son: tipo de tarea, procedimientos implicados, nivel de procesamiento cognitivo y pautas de enseñanza para trabajar la imagen. Una de las editoriales destaca frente a las demás por ser la que mejor promueve la alfabetización gráfica en las actividades sobre el cuerpo humano y también se analizan las distintas contribuciones de las otras editoriales. Aunque los criterios propuestos ayudan a la selección del libro de texto más adecuado desde el punto de vista de la competencia gráfica, también ponen de manifiesto la necesidad de cambiar la concepción y uso de las imágenes como herramienta de aprendizaje.

  17. Management der akuten Sigmadivertikulitis im jungen Alter

    Directory of Open Access Journals (Sweden)

    Ritz J-P

    2007-01-01

    Full Text Available Es gibt in der Literatur eine anhaltende kontroverse Diskussion über die Verlaufsform einer akuten Sigmadivertikulitis und deren Management bei jungen Patienten mit Divertikelerkrankung. In älteren Studien wird bei jungen Patienten mit unter 50 Jahren eine operative Sanierung im Sinne einer Sigmaresektion bereits nach dem ersten Schub empfohlen und hat sich so als grundsätzliche Operationsindikation in den Leitlinien niedergeschlagen. Jüngere Studien zeigen jedoch zum einen eine Verschiebung des Patientenalters zu einem früheren Erkrankungsbeginn. Zum anderen scheint bei Patienten mit unter 50 Jahren die Gefahr einer Divertikelperforation und die eines Rezidivs nicht mehr so hoch zu sein. Hieraus folgern viele Autoren, die Therapie der Divertikulitis vom Patientenalter unabhängig zu sehen. Jedoch konnten alle Studien, in denen die Altersgrenze bei 40 Jahren gesetzt wurde, zeigen, daß bei der jungen Patientengruppe die Sigmadivertikulitis aggressiver auftritt. Die bisher zumeist gesetzte Altersgrenze von 50 Jahren zur Unterscheidung von jungen und älteren Patienten sollte aufgrund der zunehmenden Verschiebung des Erkrankungsalters neu evaluiert werden. Des weiteren ist zu erwägen, Patienten mit einem Sigmadivertikulitisschub vor dem 40. Lebensjahr aufgrund der höheren Aggressivität und dem zu erwartenden langen Verlauf mit hoher Rezidivgefahr bereits nach diesem ersten Schub zu operieren.

    In 1973, immediately following the Arab Oil Embargo, the Energy Resources Center, University of Illinois at Chicago initiated an innovative annual public service program called the Illinois Energy Conference. The objective was to provide a public forum each year to address an energy or environmental issue critical to the state, region and nation. Twenty years have passed since that inaugural program, and during that period we have covered a broad spectrum of issues including energy conservation nuclear power, Illinois coal, energy policy options, natural gas, alternative fuels, new energy technologies, utility deregulation and the National Energy Strategy.

    2015-01-06

    Ion mobility spectrometry (IMS) is a fast and sensitive analytical method which operates at the atmospheric pressure. To enhance the capability of IMS for the analysis of mixtures, it is often used with preseparation techniques, such as GC or HPLC. Here, we report for the first time the coupling of the thin-layer chromatography and IMS. A variety of coupling schemes were tried that included direct electrospray from the TLC strip tip, indirect electrospray from a needle connected to the TLC strip, introducing the moving solvent into the injection port, and, the simplest way, offline introduction of scratched or cut pieces of strips into the IMS injection port. In this study a special solvent tank was designed and the TLC strip was mounted horizontally where the solvent would flow down. A very small funnel right below the TLC tip collected the solvent and transferred it to a needle via a capillary tubing. Using the TLC-ESI-IMS technique, acceptable separations were achieved for two component mixtures of morphine-papaverine and acridine-papaverine. A special injection port was designed to host the pieces cut off the TLC. The method was successfully used to identify each spot on the TLC by IMS in a few seconds.

    Transport systems of the future will be more efficient and less polluting than the current systems. Intermodal transport is an interesting alternative, i.e. truck/railway or truck/ship systems. In spite of extensive state funding, systems of this type still fail to meet the standards to make them competitive. The contribution compares monomodal and intermodal systems and attempts to defines strategies to make intermodal systems more successful. [German] Vor dem Hintergrund des in den vergangenen Jahren kontinuierlich gestiegenen Verkehrsaufkommens und den damit in engem Zusammenhang stehenden Umweltproblemen sind fuer die Zukunft leistungsfaehige Transportsysteme gefordert, die eine weiter wachsende Verkehrsnachfrage im Vergleich zu den zur Zeit im Einsatz befindlichen Systemen umweltvertraeglicher abwickeln. Eine aussichtsreiche Alternative stellt in diesem Zusammenhang der Kombinierte Verkehr (KV) als intermodale Verkehrsform von Lkw und Eisenbahn bzw. Schiff dar. Trotz einer Vielzahl in der Vergangenheit erfolgter staatlicher Foerdermassnahmen fehlt es dem KV nach wie vor in vielen Bereichen an der noetigen Wettbewerbsfaehigkeit, was sich in einem entsprechend niedrigen Marktanteil am Gueterverkehrsmarkt niederschlaegt. Im vorliegenden Beitrag wird dieser bei vordergruendiger Betrachtung zunaechst als Widerspruch anmutende Sachverhalt im Rahmen einer vergleichenden Analyse von verschiedenen monomodalen Transportsystemen und dem KV untersucht. Die dabei ermittelten Ergebnisse dienen im weiteren als Ausgangspunkt zur Diskussion von Ansaetzen, die ein modernes betriebliches Informationsmanagement im Hinblick auf eine Verbesserung der Akzeptanz des KV bietet.

    2015-01-01

    This study is based on both the recent and the predicted twenty first century climatic and hydrological changes over the mountainous Upper Indus Basin (UIB), which are influenced by snow and glacier melting. Conformal-Cubic Atmospheric Model (CCAM) data for the periods 1976-2005, 2006-2035, 2041-2070, and 2071-2100 with RCP4.5 and RCP8.5; and Regional Climate Model (RegCM) data for the periods of 2041-2050 and 2071-2080 with RCP8.5 are used for climatic projection and, after bias correction, the same data are used as an input to the University of British Columbia (UBC) hydrological model for river flow projections. The projections of all of the future periods were compared with the results of 1976-2005 and with each other. Projections of future changes show a consistent increase in air temperature and precipitation. However, temperature and precipitation increase is relatively slow during 2071-2100 in contrast with 2041-2070. Northern parts are more likely to experience an increase in precipitation and temperature in comparison to the southern parts. A higher increase in temperature is projected during spring and winter over southern parts and during summer over northern parts. Moreover, the increase in minimum temperature is larger in both scenarios for all future periods. Future river flow is projected by both models to increase in the twenty first century (CCAM and RegCM) in both scenarios. However, the rate of increase is larger during the first half while it is relatively small in the second half of the twenty first century in RCP4.5. The possible reason for high river flow during the first half of the twenty first century is the large increase in temperature, which may cause faster melting of snow, while in the last half of the century there is a decreasing trend in river flow, precipitation, and temperature (2071-2100) in comparison to 2041-2070 for RCP4.5. Generally, for all future periods, the percentage of increased river flow is larger in winter than in

  15. IM Normae: A Second T Pyx? (Abstract)

    2015-12-01

    (Abstract only) T Pyx is the Galaxy's most famous recurrent nova, erupting to magnitude 6 about every 20 years. For nova hunters and variable-star observers generally, it should be quite easy to discover stars with similar properties. There are probably half a million CVs out to the distance of T Pyx, and most have an underlying structure similar to that of T Pyx: low-mass secondary, fairly massive white dwarf, short orbital period. But of these half million stars, there is no second T Pyx. The star is unique in another way: its orbital period is increasing on a timescale of 300,000 years. Like the proverbial bat out of hell. A 2002 nova eruption nominated a second star for this elite club: IM Nor, a short-orbital-period (2.5 hours) star which previously erupted in 1920. We began a program of time-series photometry to track the shallow eclipses—to test for orbital period change, the other signature of T Pyx resemblance. By 2015 we found this effect: Porb increases on a timescale of 2 million years. Thus, the two stars appear to be blowing themselves apart on a timescale of roughly a million years. This could explain why the stars are so rare: because they are rapidly self-immolating. And that could happen because the classical-nova outburst overwhelms the low-mass secondaries that live in short-period CVs—leading to unstable mass transfer which quickly evaporates the secondary. This implies that all short-Porb classical novae should be "recurrent" (erupting on a timescale of decades). Greater attention to CP Pup (1942), RW UMi (1956), GQ Mus (1983), and V Per (1887) is definitely warranted.

    Full Text Available Der männliche Hypogonadismus ist ein Zustand des Testosteronmangels, der einer Substitutionstherapie bedarf. Eine allgemein akzeptierte Definition dieses Zustandes existiert jedoch nicht; auch kann bisher nicht endgültig beantwortet werden, wie stark das Krankheitsbild mit dem zunehmendem Alter assoziiert ist und wie es in seiner Ausprägung dadurch möglicherweise modifiziert wird. Allerdings werden, ungeachtet des Alters, Serumtestosteronspiegel unter 12 nmol/l mit Begleiterscheinungen des Androgenmangels als Indikation für eine Testosteronsubstitutionstherapie betrachtet; der Ausschluß eines Prostatakarzinoms stellt hierbei eine Vorbedingung dar. Das injizierbare Testosteronenanthat erzeugt Serumspiegel, die für 2-3 Wochen über dem unteren Grenzbereich liegen. Länger wirkende Ester, die Injektionsintervalle zwischen 6 und 12 Wochen ermöglichen, sind in klinischer Entwicklung (z. B. injizierbares Testosteronundecanoat. Diese Ester sind günstig für die Substitutionstherapie bei jüngeren Männern, für ältere Patienten sind jedoch kürzer wirkende Präparate sinnvoll, da sie im Falle des Auftretens von Kontraindikationen (Prostatakarzinome oder Nebenwirkungen (Polyzythämien schneller abgesetzt werden können. Daher sollten bei älteren Männern vorzugsweise orale oder transdermale Präparate angewandt werden. Besonders letztere zeichnen sich durch eine dem physiologischen Rhythmus ähnliche Pharmakokinetik aus. Zukünftige Studien werden zeigen, ob synthetische Androgene mit geringerem prostatotropem Effekt wie 7alpha-methyl-19-Nortestosteron (MENT einen Vorteil bei der Behandlung hypogonadaler Männer bieten.

    In vielen Unternehmen werden heterogene (verschiedene) Steuerungen in einem abgestimmten Konzept kombiniert. Je nach Anwendungsfall und Rahmenbedingungen werden Kombinationen allgemein bekannter Steuerungen oder Steuerungsvarianten gemischt eingesetzt, um eine optimale Steuerung für unterschiedliche Fälle zu erreichen. Hierbei stehen neben den bekannten und weit verbreiteten Methoden, wie Material Requirements Planning (MRP) oder Kanban, auch weniger bekannte oder neue Methoden zur Auswahl, wie die Produktionssteuerung mit dezentraler, bestandsorientierter Fertigungsregelung (DBF). Kanban ist ein simples und effizientes Steuerungskonzept, das in der klassischen Form für spezifische einfache Anwendungsfälle umsetzbar ist. Hochentwickelte Steuerungsalgorithmen können helfen, komplexe Abläufe optimal abzubilden. Mit einer grundlegenden Vereinfachung der Abläufe kann allerdings in vielen Fällen ein wesentlich stärkerer und umfassender Verbesserungseffekt erzielt werden. Die wesentliche Fragestellung sollte folglich lauten: Warum ist der Ablauf nicht mit einer einfachen Steuerung wie Kanban abzubilden? Um die Vorteile des Konzepts auch in untypischen Bereichen anwenden zu können, sind jedoch verschiedene Varianten oder Kanban-ähnliche Steuerungsmethoden entstanden. Darüber hinaus sind in der Praxis hybride Steuerungen im Einsatz, welche so kombiniert werden, dass die Zusammensetzung anspruchsvolle Eigenschaftsbilder noch exakt abbildet. In der Praxis basieren die Steuerungsentscheidungen nur zu einem kleinen Teil auf den eigentlichen Steuerungsalgorithmen, wie sie uns das MRP-System zur Verfügung stellt. Moderne Steuerungswelten" schließen alle relevanten Informationsquellen in eine heterogene Entscheidungsmatrix mit ein. Letztlich zählt nicht, ob die Entscheidung auf den Informationen aus dem MRP-System oder auf Softfacts basierend getroffen wurde, sondern nur, ob die Entscheidung erfolgreich war.

    This report documents the results of an initial analysis of population and business exposure to scenario earthquakes in Washington. This analysis was conducted to support the U.S. Geological Survey (USGS) Pacific Northwest Multi-Hazards Demonstration Project (MHDP) and an ongoing collaboration between the State of Washington Emergency Management Division (WEMD) and the USGS on earthquake hazards and vulnerability topics. This report was developed to help WEMD meet internal planning needs. A subsequent report will provide analysis to the community level. The objective of this project was to use scenario ground-motion hazard maps to estimate population and business exposure to twenty Washington earthquakes. In consultation with the USGS Earthquake Hazards Program and the Washington Division of Geology and Natural Resources, the twenty scenario earthquakes were selected by WEMD (fig. 1). Hazard maps were then produced by the USGS and placed in the USGS ShakeMap archive.

  1. Instrumentale Spielformeln und Vokale Verzierungen im 16.Jahrhundert

    Directory of Open Access Journals (Sweden)

    Göllner, Theodor

    2001-12-01

    Full Text Available In the music of the 16th century, stereotype four-note formulas are found in the instrumental as well as in the vocal idiom. Although frequently identical in appearance, their functions are very different. While indispensable in the instrumental idiom, particularly in keyboard music, where they represent the very essence of instruction in 15th-century organ treatises and fundamenta, they appear in vocal music only as additions to finished compositions or existing practices. What amounts to an absolute necessity in one case is merely an ornamental supplement in the other. In vocal music it is treated as a matter of performance carried out by a qualified soloist and limited to the musical centers of Italy. The present article raises the question as to how the genuinely instrumental and widely spread keyboard practice made its impact on the vocal ornaments of the singer, whose primary concern is the musical communication of language.

    [de] Die in der Musik des 16. Jahrhunderts im Instrumentalen wie im Vokalen vorkommenden, meist viertönigen, stereotypen Formeln sind zwar in beiden Bereichen weitgehend identisch, doch von höchst unterschiedlicher Funktion. Während sie im Instrumentalen, besonders in der Tastenmusik, unverzichtbar sind und schon im 15. Jahrhundert den Kern der Orgeltraktate und Fundamenta bilden, treten sie im Vokalen zu einer fertigen Komposition oder bestehenden Praxis hinzu. Was im einen Fall eine unbedingte Notwendigkeit ist, wird im anderen zu einem nachträglichen Ornament, das sich oft erst bei der Aufftührung einstellt, den qualifizierten Solosänger voraussetzt und auf die musikalischen Zentren Italiens konzentriert war. Der Artikel versucht zu klären, wie sich das genuin instrumentale, allgemein verbreitete Tastenspiel auf die spezielle Verzierungskunst des Sängers auswirkt, dessen primäre Aufgabe es ist, Sprache musikalisch zu vermitteln.

    Full Text Available Adoption of management systems standards is a key issue in manufacturing industry in India. Following the global trend quality and environmental issues are gaining importance. However the number of ISO 14001 certified companies are much less in India as compared to ISO 9001. The integration of ISO 14001 with ISO 9001 may help companies to sustain competitive advantage and overcome disappointments with quality standards and in turn encourage companies to adopt good environmental practices. The aim of this research is to study the implementation of integrated management standards (IMS by the manufacturing organizations in India. The different aspects of integration and benefits of IMS implementation are analyzed. This r esearch is based on empirical study carried out in Indian manufacturing firms, involving the application of a questionnaire. This questionnaire was tested on 50 manufacturing companies in India. The study reveals that focus on stakeholders; top management commitment and training are critical success factors for implementation of IMS. The main benefits of integration are discussed. The small sample size is one of the major limitations of this study. The paper informs the managers in manufacturing organizations and practitioners of management system standards especially in developing countries about IMS and will enable them to adopt IMS in future so that those organizations may not implement multiple and overlapping MSS(Management System Standards.

    2008-01-01

    The emergent IMS (Internet Protocol Multimedia Subsystem) technology appears to improve the current communication technologies. Its characteristics, such as Quality of Service (QoS), make it an advantageous system for innovative applications. Providing integrated services to users is one of the main reasons for the existence of IMS. Operators provide the technology as an open source, to be able to use services developed by researchers. Combining and integrating them, users will receive completely new services. Our proposal of use for IMS is the development of a telemedicine platform, designed to support not only remote biological signal monitoring, but value-added services for diagnosis and medical care, both of these working in real time.

    1997-10-01

    The effective control of pollutants in ambient air requires their fast in situ identification and concentration determination of chemical compounds in the range of micrograms per m{sup 3}. There are attempts to use conventional analytical techniques as portable GC and GC-MS. These systems are relatively expensive. A new supersensitive ion Mobility Sensor (IMS) was developed and checked by IUT Ltd, which meets the new demands. The use of tritium sources is an advantage in comparison with other IMS being equipped by nickel-63, the application of which is rather critical in respect of the radiation protection. On the other hand an integrated separation column allows to reduce interferences by matrix effects. The technical parameters of the IUT GC- IMS and some of its most important applications are briefly presented 6 refs., 1 tab., 5 figs.

  11. Understanding Contamination; Twenty Years of Simulating Radiological Contamination

    Energy Technology Data Exchange (ETDEWEB)

    Emily Snyder; John Drake; Ryan James

    2012-02-01

    A wide variety of simulated contamination methods have been developed by researchers to reproducibly test radiological decontamination methods. Some twenty years ago a method of non-radioactive contamination simulation was proposed at the Idaho National Laboratory (INL) that mimicked the character of radioactive cesium and zirconium contamination on stainless steel. It involved baking the contamination into the surface of the stainless steel in order to 'fix' it into a tenacious, tightly bound oxide layer. This type of contamination was particularly applicable to nuclear processing facilities (and nuclear reactors) where oxide growth and exchange of radioactive materials within the oxide layer became the predominant model for material/contaminant interaction. Additional simulation methods and their empirically derived basis (from a nuclear fuel reprocessing facility) are discussed. In the last ten years the INL, working with the Defense Advanced Research Projects Agency (DARPA) and the National Homeland Security Research Center (NHSRC), has continued to develop contamination simulation methodologies. The most notable of these newer methodologies was developed to compare the efficacy of different decontamination technologies against radiological dispersal device (RDD, 'dirty bomb') type of contamination. There are many different scenarios for how RDD contamination may be spread, but the most commonly used one at the INL involves the dispersal of an aqueous solution containing radioactive Cs-137. This method was chosen during the DARPA projects and has continued through the NHSRC series of decontamination trials and also gives a tenacious 'fixed' contamination. Much has been learned about the interaction of cesium contamination with building materials, particularly concrete, throughout these tests. The effects of porosity, cation-exchange capacity of the material and the amount of dirt and debris on the surface are very important factors

    The aim of the project was to identify areas in households and the tertiary sector in which changes in behaviour could result in energy conservation and thus a reduction of greenhouse gas emissions, and to quantify the potentials for 1995, 2005 and 2020. A second focus was on the analysis and evaluation of programmes and instruments to realise the potentials. With literature evaluation, expert interviews, and a household servey potentials and further technical development have been identified. In sum, behavioural measures can contribute to the CO2 reduction by 64 million tons in 1995 in households and 27 in the commercial sector in which the potential decreases to 18 million tons in 2020 due to the autonomous technical development. Adequate promotion programmes can help to realise 20-30% of the potential by 2020. (orig.) [German] Ziel des Vorhabens war, im Sektor private Haushalte und Kleinverbrauch Bereiche zu identifizieren, in denen Verhaltensaenderungen zur Energieeinsparung fuehren koennen, und diese Potenziale fuer 1995, 2005 und 2020 zu quantifizieren. Darauf aufbauend waren Programme und Instrumente zur Umsetzung aufzuzeigen und zu bewerten. Gestuetzt auf Literaturrecherchen und Expertengespraeche wurden Einzelpotenziale, Rahmenbedingungen, Entwicklungstrends in der Technik und im Ausstattungsgrad ermittelt. Insgesamt koennten Verhaltensmassnahmen im Haushaltssektor die CO2-Emissionen im Basisjahr 1995 um 64 Mio, im Kleinverbrauch um 27 Mio t vermindern. Bis 2020 bleibt dieses Potenzial im Haushaltssektor in etwa gleich. Im Kleinverbrauch sinkt es infolge der autonomen Technikentwicklung auf 18 Mio t ab. Durch geeignete Programme koennen bis 2020 etwa 20-30% des Potenzials erreicht werden. (orig.)

    The practice of filling underground mines with nonmining residues for mining engineering reasons has a long tradition. In anticipation, in the early 1980s, of large arisings of desulphurisation residues as a result of the Ordinance on Large Firing Installations the hard coal industry committed itself to exploring ways of reutilising this material. In 1988 the North-Rhine Westphalian State Agency for Water and Waste (now named State Environmental Agency), acting on behalf of the State Government, commissioned a study on possibilities of disposing of dusts from the waste air purification stages of household waste and sewage sludge incineration plants in mines of the Ruhr district. These activities were taken up in awareness that technologies to this end were emerging in the Ruhr mining region, but also in adherence to the policy of foresighted planning. This paper gives an account of the basic ideas of safety assessment, process flows, barriers as well as the model calculations on transport that were performed as part of a research project commissioned by the Federal Ministry for Education and Research on the proof of barrier efficacy. Amongst the paper's focal issues are the insights into geochemical processes that were gained at the Geology Institute of Bonn University in the course of the above-named research project.

    Full Text Available El presente trabajo aborda el tema de imágenes pastorales en la Biblia. Diversas imágenes de Dios han sido hechas en cada cultura, así como también en la Biblia, ya que ésta fue escrita en el contexto del Antiguo Próximo Oriente y Grecia. Este trabajo identifica las imágenes pastorales en Sumeria, Asiria, Babilonia, Egipto y Grecia, destacando similitudes y diferencias en sus usos entre estas naciones e Israel, y entre el Antiguo y Nuevo Testamento. En este análisis, se distingue el uso del término “pastor” como ocupación de otros usos del término transferidos a la divinidad, a los reyes y gobernantes, así como también se distingue del uso Mesías-Pastor de las funciones pastorales del liderazgo cristiano primitivo. El trabajo invita a imaginar a Dios con otras imágenes más relevantes para la vida y cultura latinoamericana, tales como: Dios-Acompañante, Dios-Multiculturalizador/a, Dios-Pacificador/a y Dios-Madre.

    We review the radio very long baseline interferometry (VLBI) observations of the guide star, IM Peg, and three compact extragalactic reference sources, 3C 454.3, B2250+194, and B2252+172, made in support of the NASA/Stanford gyroscope relativity mission, GP-B. The main goal of the observations was the determination of the proper motion of IM Peg relative to the distant universe. VLBI observations made between 1997 and 2005 yield a proper motion of IM Peg of -20.83 $\\pm$ 0.09 mas yr$^{-1}$ in RA and -27.27 $\\pm$ 0.09 mas yr$^{-1}$ in dec, in a celestial reference frame of extragalactic radio galaxies and quasars virtually identical to the International Celestial Reference Frame 2 (ICRF2). They also yield a parallax for IM Peg of 10.37 $\\pm$ 0.07 mas, corresponding to a distance of 96.4 $\\pm$ 0.7 pc. The uncertainties are standard errors with statistical and estimated systematic contributions added in quadrature. These results met the pre-launch requirements of the GP-B mission to not discernibly degrade the es...

    Full Text Available The development of packed based multimedia networks reached a turning point when the ITU-T and the ETSIhave incorporated the IMS to the NGN. With the fast development of mobile communication more and more services andcontent are available. In contrast with fix network telephony both the services and the devices are personalized in the “mobileworld”. Services, known from the Internet - like e-mail, chat, browsing, presence, etc. – are already available via mobiledevices as well. The IMS originally wanted to exploit both the benefits of mobile networks and the fancy services of theInternet. But today it is already more than that. IMS is the core of the next generation telecommunication networks and abasis for fix-mobile convergent services. The fact however that IMS was originally a “mobile” standard, where IPv6 was notoddity generated some problems for the fix networks, where IPv4 is used. In this article I give an overview of these problemsand mention some solutions as well.

    2016-04-01

    Full Text Available Dem Zusammenhang von ausländischen Direktinvestionen (Foreign Direct Investment, FDI und Technologietransfer wird sowohl in der Forschung als auch in der politischen Analyse große Bedeutung zugeschrieben. Zahlreiche Veröffentlichungen belegen, dass FDI den Transfer von und/oder den Zugang zu Technologien erleichtert. Allerdings gibt es zu wenige empirische Studien, die diesen Zusammenhang in Bezug auf die Wirtschaft afrikanischer Staaten untersuchen. Der Autor will diese Lücke zu einem kleinen Teil schließen, indem er die Bedeutung des Technologietransfers durch den Zufluss von FDI im Energiesektor Angolas ermittelt. Seine Analyse basiert auf qualitativer Forschung in Angola im Jahr 2014. Er zeigt auf, dass sich die Erzeugung von Energie(trägern und die Verteilungsinfrastruktur - maschinelle Ausrüstung und Qualifizierung - durch den Zufluss von FDI erheblich entwickeln konnte. Allerdings gebe es keinen Beleg dafür, dass dieser Zufluss die endogenen wissenschaftlichen und technologischen Forschungspotenziale im angolanischen Energiesektor gefördert hat. Der Autor empfiehlt politische Maßnahmen zur Förderung dieser Fähigkeiten, insbesondere im Bereich der Produktion.

    Jones, William H. [Los Alamos National Laboratory

    2012-07-12

    Los Alamos National Laboratory (the Laboratory) is the nation's premier national security science laboratory. Its mission is to develop and apply science and technology to ensure the safety, security, and reliability of the United States (U.S.) nuclear stockpile; reduce the threat of weapons of mass destruction, proliferation, and terrorism; and solve national problems in defense, energy, and the environment. The fiscal year (FY) 2013-2037 Twenty-Five Year Site Plan (TYSP) is a vital component for planning to meet the National Nuclear Security Administration (NNSA) commitment to ensure the U.S. has a safe, secure, and reliable nuclear deterrent. The Laboratory also uses the TYSP as an integrated planning tool to guide development of an efficient and responsive infrastructure that effectively supports the Laboratory's missions and workforce. Emphasizing the Laboratory's core capabilities, this TYSP reflects the Laboratory's role as a prominent contributor to NNSA missions through its programs and campaigns. The Laboratory is aligned with Nuclear Security Enterprise (NSE) modernization activities outlined in the NNSA Strategic Plan (May 2011) which include: (1) ensuring laboratory plutonium space effectively supports pit manufacturing and enterprise-wide special nuclear materials consolidation; (2) constructing the Chemistry and Metallurgy Research Replacement Nuclear Facility (CMRR-NF); (3) establishing shared user facilities to more cost effectively manage high-value, experimental, computational and production capabilities; and (4) modernizing enduring facilities while reducing the excess facility footprint. Th is TYSP is viewed by the Laboratory as a vital planning tool to develop an effi cient and responsive infrastructure. Long range facility and infrastructure development planning are critical to assure sustainment and modernization. Out-year re-investment is essential for sustaining existing facilities, and will be re-evaluated on an annual

    In this research project, completely new sensors wer developed, as there was nothing comparable on the market. The development was carried out by the partners Sick and Weidmueller, with the support of MB DATA for mining details and mining law authorisation. With regard to the developed sensors, the optical sensor from the firm of Sick represents a very capable equipment. By contrast, the ultrasonic sensors have not been developed ready for authorisation yet, but the management of the firm of Weidmueller states that they will continue development in 1994. The sensor system described here was developed in the context of the research project `Automation in mining/sensor for measuring the free through cross section`. The aim of this research contract was to develop an equipment which should succeed in detecting any obstacles on the route of a vehicle. In the case of the optical sensor, this project succeeded in doing this. (orig.) [Deutsch] Bei diesem Forschungsvorhaben wurden komplett neue Sensoren entwickelt, da es vergleichbares bisher nicht auf dem Markt gab. Die Entwicklung wurde durch die Kooperationspartner Sick und Weidmueller, mit Unterstuetzung bei bergbauspezifischen Details und der bergbaugerechten Zulassung durch MB DATA, durchgefuehrt. Im Hinblick auf die entwickelte Sensorik stellt vor allem der optischen Sensor der Firma Sick ein sehr leistungsfaehiges Geraet dar. Die Ultraschallsensorik hingegen ist noch nicht bis zur Zulassungsreife entwickelt worden, es liegen aber Aussagen der Geschaeftsleitung der Firma Weidmueller vor, mit der Weiterentwicklung auch im Jahre 1994 taetig zu sein. Das hier beschriebene Sensorsystem wurde im Rahmen des Forschungsvorhabens `Automatisierung im Bergbau / Sensor zur Erfassung des freien Durchgangsquerschnittes` entwickelt. Ziel dieses Forschungsauftrages war es, ein Geraet zu entwickeln, mit dem es gelingen soll, eventuelle Hindernisse innerhalb der Wegstrecke eines Fahrzeugs zu detektieren. Im Falle des optischen

    Full Text Available Changes in kinship relations are part of the broad social change in all African societies. This article highlights trends and characteristics of changing kinship relations in West Africa. Its analysis focuses on the twentieth century, which was shaped by the colonial conquest and profound societal transformations like the political independence of the African colonies. In analysing three important kinship relations – parent–child relations, marriage, and care for the elderly – this article depicts the trends and conditions of historical change of these relationships. It also shows whether and how these changes are accompanied by conflict, and how people refer to the different ways of dealing with those conflicts. The article is based on empirical data from three thematically intertwined research projects. Der vorliegende Artikel thematisiert Tendenzen und Merkmale des Wandels verwandtschaftlicher Beziehungen im Norden von Benin und Togo und deren Wechselspiel mit Tendenzen des allgemeinen gesellschaftlichen Wandels. Der Blick liegt dabei auf dem 20. Jahrhundert, das von den tief greifenden Veränderungen gekennzeichnet ist, die die koloniale Eroberung und die politische Unabhängigkeit der Kolonien auf dem afrikanischen Kontinent auslöste. Anhand von drei Arten verwandtschaftlicher Beziehungen – Eltern-Kindbeziehungen, Heiratsbeziehungen und innerfamiliäre Altersversorgung – werden zentrale Tendenzen und Bedingungen dieses historischen Wandels beschrieben. Dabei wird auch der Frage nach der Konflikthaftigkeit sowie nach dem Umgang mit Konflikten im Zuge dieser Wandlungsprozesse nachgegangen. Der Beitrag basiert auf empirischen Daten, die im Rahmen von thematisch miteinander verwobenen Forschungsprojekten erhoben wurden.

If one compares the practice of dentistry and the nature of dental education in 1888 with that of 1988, and then tries to project what they will be like in the year 2088, we have a difficult task indeed. As Alvin Toffler has pointed out in his book Future Shock, we are in an ever escalating period of change. Dentistry and dental education will change much more in the next one hundred years than they have in the last one hundred years.

  10. Rethinking Individual Authorship: Robert Burns, Oral Tradition, and the Twenty-First Century

    Directory of Open Access Journals (Sweden)

    2011-10-01

    Full Text Available The songs of late-eighteenth-century Scottish poet Robert Burns provide a rich case study of literature that challenges existing notions of the author as an autonomous entity. Responding to twenty-first-century examples of contested issues of intellectual property and plagiarism in an age of digital media, this project illustrates the ways in which precepts of oral tradition can inform our thinking about cultural production within contexts seemingly permeated by ever-present literacy or text-based thinking in order to provide a new outlook on such situations of artistic borrowing or “plagiarism.”

    Full Text Available In der Literatur zur qualitativen Inhaltsanalyse werden verschiedene Varianten des Verfahrens unterschieden, darunter beispielsweise die inhaltlich-strukturierende, die evaluative, die skalierende, die zusammenfassende oder die typenbildende Inhaltsanalyse. Dabei bleibt jedoch unklar, wie diese verschiedenen Varianten sich zueinander verhalten. In dem vorliegenden Beitrag werden die verschiedenen Versionen qualitativer Inhaltsanalyse beschrieben und in Beziehung gesetzt. Dabei ergeben sich zwei Basisformen qualitativer Inhaltsanalyse: die strukturierende qualitative Inhaltsanalyse und die qualitative Inhaltsanalyse durch Extraktion. Die anderen Varianten werden nicht als eigenständige Versionen rekonstruiert, sondern als Variationen im Ablauf der strukturierenden Inhaltsanalyse. Darüber hinaus sind weitere Variationen möglich und sinnvoll, die abschließend im Sinne eines "Werkzeugkastens" qualitativer Inhaltsanalyse dargestellt werden.

    2007-09-01

    Full Text Available Motivation: This paper will discuss sensitivity issues in rotor speed estimation for induction machine (IM drives using only voltage and current measurements. A supervised estimation algorithm is proposed with the aim to achieve good performances in the large variations of the speed. After a brief presentation on discrete feedback structure of the estimator formulated from d-q axis equations, we will expose its performances for machine parameters variations.Method: Hyperstability concept was applied to the synthesis adaptation low. A heuristic term is added to the algorithm to maintain good speed estimation factor in high speeds.Results: In simulation, the estimation error is maintained relatively low in wide range of speeds, and the robustness of the estimation algorithm is shown for machine parametric variations.Conclusions: Sensitivity analysis to motor parameter changes of proposed sensorless IM is then performed.

    Full Text Available As the network convergence with services for both static and mobile networks has been the principal object of the next generation networks, the recent research focus is converging in the direction of standardizing common infrastructure based on all-IP networks. IMS is a recent initiative. Moreover, designing and deploying a standard QoS provisioning mechanisms in large networks is not a trivial matter. IPTV services are considered between the important IMS flow, the actual QoS management mechanisms proposed by 3GPP allow providing the IMS network components control and efficient service delivery, however the 3GPP approach focuses entirely on the step of providing the service, but there is no mechanism for monitoring Qos dynamically. This paper discusses the issues, design and analysis related to on demand dynamic QoS control in these next generation networks and fuss both Quality of Service (QoS information signaling and IPTV traffic engineering options that may serve as key components of IPTV service specific QoS policies, which are designed to accommodate with customer requirements and resource availability by using the eTOM process to monitor the Qos values and to propose optimal solution to provide the quality of delivered content. The eTOM process interact with implemented marking entities which execute an algorithm to marking IPTV packets, this cooperation must improve the quality of service of the IPTV traffic

    This version of the Impact of Sector Energy Technologies (ImSET) model represents the ''next generation'' of the previously developed Visual Basic model (ImBUILD 2.0) that was developed in 2003 to estimate the macroeconomic impacts of energy-efficient technology in buildings. More specifically, a special-purpose version of the 1997 benchmark national Input-Output (I-O) model was designed specifically to estimate the national employment and income effects of the deployment of Office of Energy Efficiency and Renewable Energy (EERE) -developed energy-saving technologies. In comparison with the previous versions of the model, this version allows for more complete and automated analysis of the essential features of energy efficiency investments in buildings, industry, transportation, and the electric power sectors. This version also incorporates improvements in the treatment of operations and maintenance costs, and improves the treatment of financing of investment options. ImSET is also easier to use than extant macroeconomic simulation models and incorporates information developed by each of the EERE offices as part of the requirements of the Government Performance and Results Act.

    With 570 concrete poles and 80 km of tubes, 100,000 m{sup 3} of ground serve as a cold and heat storage resservoir for a building. The building houses a printing shop, which needs cooling in summer and heating in winter. The energy pole system can be used as a dual system for heating and cooling in both seasons. The project is a pilot project of the BWE (Swiss General Office for Utilities and Power Supply), who also started an extensive accompanying measurig campaign. The results during the first year of operation were very positive, and the performance of the energy pole system was up to expectations. (orig.) [Deutsch] Mittelpunkt der PAGO-Energietechnik ist das Energiepfahlsystem. Mittels 570 Betonpfaehlen und 80 km Rohrschlangen wird das Erdreich unter dem Gebaeude als ueber 100.000 m{sup 3} grosser Waerme- und Kaeltespeicher genutzt. Ueber dieses Energiepfahlsystem wird dieser Druckereibetrieb mit hohen Anforderungen an das Raumklima und viel Maschinenabwaerme sehr umweltschonend im Winter behizt und im Sommer gekuehlt. Das Besondere an diesem System ist diese ganzjaehrige Doppelnutzung zu Heiz- und Kuehlzwecken. Aus diesem Grunde wurde dieses Projekt vom Bundesamt fuer Energiewirtschaft (BEW) als Pilot- und Demonstrationsprojekt anerkannt. Zur Ueberpruefung von dessen Ausbeute und der Wirksamkeit der gesamten Energietechnik wurde vom BEW ein umfangreiches Messprojekt gestartet. Der Innovationswert der PAGO -Energietechnik liegt allerdings nicht allein im Einsatz der alternativen Komponenten. Mindestens so wichtig ist die Konzeption und die Feinabstimmung der gesamten Energietechnik. Der Betrieb lief im ersten Betriebsjahr sehr positiv und von Anfang an ohne groessere Probleme. Das Energiepfahlsystem konnte im wesentlichen die Erwartungen erfuellen. (orig.)

    The massive growth of volatile and partially distributed generation as it is requested for achieving the EU climate targets and the environmental concept of the German Federal Government means a big challenge for the future roles of sale, trade, transmission system operators and distribution system operators. The involved parties agree that in future a smart grid will be needed for providing for a stable system operation along with affordable cost for storage systems and network expansion. It is not clear however what the smart grid really will be composed of. In Germany the publicly funded programme ''E-Energy'' is driving 6 projects running between 2009 and 2012 and implementing different visions of a smart energy system. First results are available now - amongst others also from the project MeRegio which is in the focus of this report. The first part of the paper discusses the flexibility of consumption as observed among the thousand pioneer customers. It evaluates how sustainable the adaptions of the consumption to the dynamic tariffs and thus to the production based on renewable resources are.

    Full Text Available [english] Background: Breaking bad news is a frequent and difficult communication situation in clinical practice. Informing patients about bad news is part of physicians’ tasks. Nurses may support patients during the process of realising bad news on a cognitive as well as emotional level. Empirical studies show that experiential courses are effective measures to train communication skills. This paper presents the course concept of an interprofessional teaching session for medical and nursing students on the communication with seriously ill patients. Description of the project: Since 2002, 54 participants took part in seven courses. Teaching aims are the development of competences to provide feedback as well as communication skills with respect to discussions with seriously ill patients. In addition students get to know the specific tasks both professions encounter in the context of discussions with patients who had been diagnosed with a serious illness. Role plays with simulated patients, small group discussions as well as a session with clinically experienced physicians and nurses are the main teaching methods. Conclusion: The optional course has been well accepted by both student groups. In addition to the analysis of individual communication skills participants use the collaborative teaching sessions to discuss the options of an interprofessional approach of breaking bad news. There is a lack of scientific literature regarding the criteria of interprofessional concepts of breaking bad news. Such research is necessary to define specific teaching aims of collaborative courses on disclosing bad news and will serve as a fundament for future evaluation studies.

    Full Text Available Die Lehren Carl Schmitts haben wieder einmal Hochkonjunktur. Insbesondere sein von der Unterscheidung zwischen Freund und Feind bestimmter Begriff des Politischen und die Idee vom Ausnahmezustand, in dem das Recht der Normallage nicht gelte, sind derzeit aktuell. Die Reaktualisierung ist vor allem der Kriegsrhetorik geschuldet, die sich im Kampf gegen den internationalen Terrorismus etabliert. Schmitts Begrifflichkeit wird in Anspruch genommen, um diverse Antiterrormaßnahmen der normalen juristischen Beurteilung zu entziehen. Die durch souveräne politische Entscheidung ausgerufene Ausnahme soll die Geltung des Rechts suspendieren. Dabei droht die Ausnahme zur Regel zu werden. Der dadurch behauptete Vorrang des Politischen wird im Rahmen einer Analyse der Schriften Schmitts und der internationalen Rezeption seiner Theorien einer kritischen Prüfung unterzogen und zurückgewiesen.

    Ion-mobility spectroscopy (IMS) was evaluated as a high-throughput, cheap, and efficient analytical tool for detecting residues of tetrahydrocannabinol (THC) on hands. Regarding the usefulness of hand residues as potential samples for determining THC handling and abuse, we studied the correlation between data obtained from cannabis consumers who were classified as positive after saliva analysis and from those who were classified as positive on the basis of the information from hand-residue analysis. Sampling consisted of wiping the hands with borosilicate glass microfiber filters and introducing these directly into the IMS after thermal desorption. The possibility of false positive responses, resulting from the presence of other compounds with a similar drift time to THC, was evaluated and minimised by applying the truncated negative second-derivative algorithm. The possibility of false negative responses, mainly caused by competitive ionisation resulting from nicotine, was also studied. Graphical abstract THC residues: from hands to analytical signals.

    Tribocontact between cam follower and roller tappet involves mixing and limiting friction states, which causes wear in the form of adhesive corrosion and pitting of surfaces. In cooperation with Purdue University, the influence of microgeometry (surface roughness) and macrogeometry (surface shape) was investigated in order to optimize lubrication for EHD lubrication conditions in contact, thus preventing wear and failure. This component project involves pressure and temperature measurements of cam follower and roller tappet tribocontact using flash-deposited thin film probes. The results are to provide information on design optimization. [German] Im Tribokontakt Nocken-Rollenstoessel herrschen vorwiegend Misch- und Grenzreibungszustaende. Dies fuehrt zu erheblichem Verschleiss in Form von adhaesiv bedingtem Fressen und Pittingbildung durch Oberflaechenzerruettung. Ziel dieses Forschungsvorhabens ist es, in Kooperation mit der Partnerhochschule ''Purdue University'' in den USA, den Einfluss der Mikrogeometrie (Oberflaechenrauheiten) und Makrogeometrie (Oberflaechenform) des Tribokontaktes Nocken-Rollenstoessel hinsichtlich des Betriebsverhaltens zu untersuchen, um Kenntnisse zur Verbesserung der Schmierbedingungen zu gewinnen, so dass im Kontakt elastohydrodynamische (EHD) Schmierungsverhaeltnisse realisiert werden und dadurch ein Ausfall aufgrund von Verschleiss ausgeschlossen wird. Im Rahmen dieses Teilvorhabens sollten Druck- und Temperaturmessungen mittels aufgedampfter Duennschichtaufnehmer im Tribokontakt, Nocken-Rollenstoessel, durchgefuehrt werden, um die theoretischen Forschungsarbeiten, welche in der Purdue University erarbeitet werden, zu untermauern. Beide Arbeiten werden somit neue Erkenntnisse zur konstruktiven Auslegung von verschleissfreien Nocken-Stoessel-Paarungen liefern. (orig.)

    The incorporation of the hydroacoustic station HA04, Crozet Islands, France, into the International Monitoring System (IMS) of the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO) is a 17 year saga that had a happy ending on 29 December 2016. On that day, following a major engineering and logistical undertaking, the station was successfully installed. While still in its initial testing phase, HA04 sends continuously quality data at the International Data Centre (IDC), pending official certification and promotion to mainstream operational status. Similarly to most other cabled hydroacoustic stations in the IMS, HA04 is comprised of two triplets of moored hydrophones deployed on both sides of Possession Island (Crozet Islands) sending uninterrupted data to a shore facility via submarine fiber optic cables. The designed frequency pass-band is 1 - 100 Hz. Data are relayed to Vienna via a shore based satellite link in real time. According to CTBTO's standard requirements, the design life of HA04 is at least 20 years, maintenance-free for the underwater system. An outline of the main phases of this project, highlights from the installation operations and examples of received hydroacoustic signals associated with recent underwater seismic activity in the Indian Ocean as well as vocalizations from marine mammals acquired by the new HA04 are presented here. HA04 is scheduled to be fully integrated into the operational platform of IDC in the next six months, which will enable registered researchers to access archived monitoring data and processing software, or via the National Data Centres (NDCs).

    Full Text Available A large number of projects failed because of concentrating on developing new software. The Main drawbacks of new software development are more costly, and need maintenance. Reuse is solution of these problems that caused the widespread usage of object oriented (OO development. Object oriented development is the backbone of component-based development (CBD. CBD facilitates reuse of the existing components (by customizing with the new ones. Main advantages of reusable components are more reliable, saved time and reduced cost. CBD approach is different from traditional/new software development. Several models have been proposed for traditional software development such as Waterfall, Rapid Application Development (RAD, Evolutionary, Rational Unified Process (RUP and agile. Whereas the popular CBD models, for customized development, are V, Y, Umbrella and W. Almost all software development companies, both the new software and customized software have to be developed. Therefore majority of the software development companies face problem to select and implement an appropriate process model for the both kinds of developments. To address this problem, the existing RUP and CBD models do work to some extent but the authors intend to propose an extended CBD model that it equally offers its benefits for new and customized developments. The experimental data is taken from a case study to develop IP Multimedia Sub System (IMS-based examination application using iPhone to evaluate the proposed model. The results provide evidence that the extended CBD model can be equally beneficial for the development of both new and customization components for IMS-based applications.

    Full Text Available The first 13 years of the twenty-first century have begun with a series of widespread, long and intensive droughts around the world. Extreme and severe-to-extreme intensity droughts covered 2%–6% and 7%–16% of the world land, respectively, affecting environment, economies and humans. These droughts reduced agricultural production, leading to food shortages, human health deterioration, poverty, regional disturbances, population migration and death. This feature article is a travelogue of the twenty-first-century global and regional droughts during the warmest years of the past 100 years. These droughts were identified and monitored with the National Oceanic and Atmospheric Administration operational space technology, called vegetation health (VH, which has the longest period of observation and provides good data quality. The VH method was used for assessment of vegetation condition or health, including drought early detection and monitoring. The VH method is based on operational satellites data estimating both land surface greenness (NDVI and thermal conditions. The twenty-first-century droughts in the USA, Russia, Australia and Horn of Africa were intensive, long, covered large areas and caused huge losses in agricultural production, which affected food security and led to food riots in some countries. This research also investigates drought dynamics presenting no definite conclusion about drought intensification or/and expansion during the time of the warmest globe.

    Arctic climate change in the Twenty-first century is simulated by the Community Climate System Model version 3.0 (CCSM3). The simulations from three emission scenarios (A2, A1B and B1) are analyzed using eight (A1B and B1) or five (A2) ensemble members. The model simulates a reasonable present-day climate and historical climate trend. The model projects a decline of sea-ice extent in the range of 1.4-3.9% per decade and 4.8-22.2% per decade in winter and summer, respectively, corresponding to the range of forcings that span the scenarios. At the end of the Twenty-first century, the winter and summer Arctic mean surface air temperature increases in a range of 4-14 C (B1 and A2) and 0.7-5 C (B1 and A2) relative to the end of the Twentieth century. The Arctic becomes ice-free during summer at the end of the Twenty-first century in the A2 scenario. Similar to the observations, the Arctic Oscillation (AO) is the dominant factor in explaining the variability of the atmosphere and sea ice in the 1870-1999 historical runs. The AO shifts to the positive phase in response to greenhouse gas forcings in the Twenty-first century. But the simulated trends in both Arctic mean sea-level pressure and the AO index are smaller than what has been observed. The Twenty-first century Arctic warming mainly results from the radiative forcing of greenhouse gases. The 1st empirical orthogonal function (explains 72.2-51.7% of the total variance) of the wintertime surface air temperature during 1870-2099 is characterized by a strong warming trend and a ''polar amplification''-type of spatial pattern. The AO, which plays a secondary role, contributes to less than 10% of the total variance in both surface temperature and sea-ice concentration. (orig.)

    Understanding how herbicides affect plant reproduction and growth is critical to develop herbicide toxicity model and refine herbicide risk assessment. Although our knowledge of herbicides toxicity mechanisms at the physiological and molecular level in plant vegetative phase has increased substantially in the last decades, few studies have addressed the herbicide toxicity problematic on plant reproduction. Here, we determined the long-term (4-8 weeks) effect of a chiral herbicide, imazethapyr (IM), which has been increasingly used in plant crops, on floral organ development and reproduction in the model plant Arabidopsis thaliana. More specifically, we followed the effect of two IM enantiomers (R- and S-IM) on floral organ structure, seed production, pollen viability and the transcription of key genes involved in anther and pollen development. The results showed that IM strongly inhibited the transcripts of genes regulating A. thaliana tapetum development (DYT1: DYSFUNCTIONAL TAPETUM 1), tapetal differentiation and function (TDF1: TAPETAL DEVELOPMENT AND FUNCTION1), and pollen wall formation and developments (AMS: ABORTED MICROSPORES, MYB103: MYB DOMAIN PROTEIN 103, MS1: MALE STERILITY 1, MS2: MALE STERILITY 2). Since DYT1 positively regulates 33 genes involved in cell-wall modification (such as, TDF1, AMS, MYB103, MS1, MS2) that can catalyze the breakdown of polysaccharides to facilitate anther dehiscence, the consistent decrease in the transcription of these genes after IM exposure should hamper anther opening as observed under scanning electron microscopy. The toxicity of IM on anther opening further lead to a decrease in pollen production and pollen viability. Furthermore, long-term IM exposure increased the number of apurinic/apyrimidinic sites (AP sites) in the DNA of A. thaliana and also altered the DNA of A. thaliana offspring grown in IM-free soils. Toxicity of IM on floral organs development and reproduction was generally higher in the presence of the R-IM

Se realizó una búsqueda sistemática de la literatura médica acerca de la cefalea abarcando su fisiopatología, clasificación y, específicamente, el uso de imágenes diagnósticas. Para ello se hizo búsqueda en diferentes bases de datos según las palabras claves indicadas. El abordaje clínico y la diferenciación entre el tipo de cefalea es primordial para decidir el beneficio y la necesidad del uso de imágenes diagnósticas. Las neuroimágenes no son comúnmente solicitadas en pacientes con cefalea primaria, se comienza la sospecha clínica ante la presencia de señales de alarma. Las cefaleas secundarias requieren un estudio más extenso en los cuales se incluye la toma de imágenes radiológicas. Teniendo en cuenta los beneficios de la TC y la RM que se exponen en esta revisión, la TC es preferida en situaciones de urgencia, y para aquellas que no lo son, la RM es más adecuada.

    Full Text Available In this paper we tackle the mobility issue in IP Multimedia Subsystem (IMS. Although IMS was designedto integrate different access networks, mobility management among these networks is still unresolved. We propose a novel hybrid mobility management scheme, based on tight cooperation between fast handovers for mobile IPv6 (FMIPv6 and session initiation protocol (SIP to ensure an uninterrupted real-time service. Moreover, the new Media Independent Handover (MIH service is integrated into IMS architecture in order to perform intelligent and accurate horizontal and vertical handovers. We investigate two handover cases: selected handover and forced handover. Selected handover takes place when user equipment (UE is connected to the network via two interfaces at the same time and decides to upgrade the quality of its connection following a given criterion (i.e. cost, bandwidth…etc without having any difficulty in the previous link. As far as forced handover is concerned, it occurs when thesignal reaches a critical level and UE is forced to make a handover in order to maintain the ongoing communication. This case is managed in two phases. The first one or the fast phase is handled by FMIPv6 protocol to preserve as soon as possible packets of the ongoing communication. The second one or the slow phase is handled by SIP protocol to optimize packet delivery route. By doing so, we exploit the benefits of both network layer and application mobility protocols to ensure a continuous session over the two networks without imposing new elements to the network. Through a comparison with other mobility mechanisms, we show in the analytic analysis that our hybrid scheme presents better results in terms of handover latency and packet loss.

    2004-01-01

    A novel electric vehicle (EV) induction motor (IM) controller based on voltage-fed inverter is presented. It is shown that the proposed adaptive control algorithm effectively both simplifies the structure and expands the capacity of controller. The relationship between stator's voltage and that of current under rotor's flux-oriented-coordinates is first introduced, and then the structure of vector control is analyzed, in which voltage compensation is inducted as the core feedback procedure. Experiments prove that, together with a facility for realization, a smooth transition, a prompt torque response and small concussion are gained. Extensive research conducted by varying parameters that result in practical ripple is proposed in conclusion.

    We study the two-dimensional affine Toda field equations for affine Lie algebra $\\hat{\\mathfrak{g}}$ modified by a conformal transformation and the associated linear equations. In the conformal limit, the associated linear problem reduces to a (pseudo-)differential equation. For classical affine Lie algebra $\\hat{\\mathfrak{g}}$, we obtain a (pseudo-)differential equation corresponding to the Bethe equations for the Langlands dual of the Lie algebra $\\mathfrak{g}$, which were found by Dorey et al. in study of the ODE/IM correspondence.

    NASA and ESA are planning the joint Europa Jupiter System Mission (EJSM) to the Jupiter system with specific emphases on Europa and Ganymede from these respective space agencies. The Japanese Space Agency is also planning an orbiter mission to explore Jupiter’s magnetosphere and the Galilean satellites. For NASA’s Jupiter Europa Orbiter (JEO) we are developing the 3D Ion Mass Spectrometer (IMS) with two main goals which can also be applied to the other Galilean moons, 1) measure the plasma interaction between Europa and Jupiter’s magnetosphere and 2) infer the 4π surface composition to trace elemental and significant isotopic levels. The first goal supports the magnetometer (MAG) measurements, primarily directed at detection of Europa’s sub-surface ocean, while the second gives information about transfer of material between the Galilean moons, and between the moon surfaces and subsurface layers putatively including oceans. The measurement of the interactions for all the Galilean moons can be used to trace the in situ ion measurements of pickup ions back to either Europa’s or Ganymede’s surface from the respectively orbiting spacecraft. The IMS instrument, being developed under NASA’s Astrobiology Instrument Development Program (ASTID), would maximally achieve plasma measurement requirements for JEO and EJSM while moving forward our knowledge of Jupiter system composition and source processes to far higher levels than previously envisaged. The ASTID-supported IMS, applicable to the NASA spacecraft, is designed to operate in a high radiation environment with minor and trace ion detection capability. The latter goal is achieved by measuring pickup ions at spacecraft altitudes and using a 3D hybrid model of the interaction in order to construct 3D global model of the electric and magnetic fields around these bodies. The pickup ion trajectories can then be traced back down to the surface. In the case of Europa we also show that Europa’s ionosphere is

  10. Spent nuclear fuel project high-level information management plan

    Energy Technology Data Exchange (ETDEWEB)

    Main, G.C.

    1996-09-13

    This document presents the results of the Spent Nuclear Fuel Project (SNFP) Information Management Planning Project (IMPP), a short-term project that identified information management (IM) issues and opportunities within the SNFP and outlined a high-level plan to address them. This high-level plan for the SNMFP IM focuses on specific examples from within the SNFP. The plan`s recommendations can be characterized in several ways. Some recommendations address specific challenges that the SNFP faces. Others form the basis for making smooth transitions in several important IM areas. Still others identify areas where further study and planning are indicated. The team`s knowledge of developments in the IM industry and at the Hanford Site were crucial in deciding where to recommend that the SNFP act and where they should wait for Site plans to be made. Because of the fast pace of the SNFP and demands on SNFP staff, input and interaction were primarily between the IMPP team and members of the SNFP Information Management Steering Committee (IMSC). Key input to the IMPP came from a workshop where IMSC members and their delegates developed a set of draft IM principles. These principles, described in Section 2, became the foundation for the recommendations found in the transition plan outlined in Section 5. Availability of SNFP staff was limited, so project documents were used as a basis for much of the work. The team, realizing that the status of the project and the environment are continually changing, tried to keep abreast of major developments since those documents were generated. To the extent possible, the information contained in this document is current as of the end of fiscal year (FY) 1995. Programs and organizations on the Hanford Site as a whole are trying to maximize their return on IM investments. They are coordinating IM activities and trying to leverage existing capabilities. However, the SNFP cannot just rely on Sitewide activities to meet its IM requirements

    Objective To elucidate the inhibitory effects of recombinant Chinese scorpion neurotoxin BmK IM on seizures induced by pentylenetetrazol (PTZ) and the possible mechanism.Methods After purifying recombinant BmK IM from an E. coli cell line, its toxicity (both LD50 and minimum lethal dose) on rats was determined. BmK IM was then microinjected into the CA3 region of the right hippocampus and its ability to inhibit the effects of an intraperitoneal injection of PTZ was assessed. The effects of BmK IM on the electrophysiological properties of isolated CA3 pyramidal neurons were then studied using whole-cell patch clamp techniques.Results BmK IM can significantly prolong the latent period of epileptic seizures, decrease the degree of seizures, and decrease the frequency of epileptiform discharges induced by PTZ. At the same time, 24h after injection of BmK IM into the hippocampal tissue, BmK IM significantly reduces the concentration of the neurotransmitter glutamate and alleviates PTZ-induced lesions in the hippocampus. Whole-cell patch clamp recordings indicate that BmK IM inhibits INa of rat hippocampal neurons in a dose-dependent manner. BmK IM significantly shifts the activation curve of INa in a positive direction, indicating that BmK IM enhances the threshold potential of INa.Conclusions BmK IM has significant anti-epileptic properties, and may prove useful as a drug in the therapy of epilepsy. The inhibitory effects of BmK IM on seizures caused by pentylenetetrazol might depend on reductions in the release of presynaptic glutamate via the blocking of Na+ channels.

    The Interval Management (IM) Avionics Phase 2 flight test used three aircraft over a nineteen day period to operationally evaluate a prototype IM avionics. Quantitative data were collected on aircraft state data and IM spacing algorithm performance, and qualitative data were collected through end-of-scenario and end-of-day flight crew surveys. The majority of the IM operations met the performance goals established for spacing accuracy at the Achieve-by Point and the Planned Termination Point, however there were operations that did not meet goals for a variety of reasons. While the positive spacing accuracy results demonstrate the prototype IM avionics can contribute to the overall air traffic goal, critical issues were also identified that need to be addressed to enhance IM performance. The first category was those issues that impacted the conduct and results of the flight test, but are not part of the IM concept or procedures. These included the design of arrival and approach procedures was not ideal to support speed as the primary control mechanism, the ground-side of the Air Traffic Management Technology Demonstration (ATD-1) integrated concept of operations was not part of the flight test, and the high workload to manually enter the information required to conduct an IM operation. The second category was issues associated with the IM spacing algorithm or flight crew procedures. These issues include the high frequency of IM speed changes and reversals (accelerations), a mismatch between the deceleration rate used by the spacing algorithm and the actual aircraft performance, and some spacing error calculations were sensitive to normal operational variations in aircraft airspeed or altitude which triggered additional IM speed changes. Once the issues in these two categories are addressed, the future IM avionics should have considerable promise supporting the goals of improving system throughput and aircraft efficiency.

Obwohl sie der sogenannten neuen Welle des Autorenkinos („novaja režisserskaja volna“ zugeordnet werden, fechten die Positionen, die diese Regisseurinnen gegenüber ihren Vorgängern, aber auch ihren Zeitgenossen einnehmen, sowohl in Russland als auch dem Westen eine einfache Zuordnung an. Die Filme bieten einen Einblick in das Anliegen der Regisseurinnen, die gesellschaftlichen und emotionalen Sorgen ihrer Generation auf eine ehrliche und realistische Art und Weise auszudrücken. Eine sorgfältige Untersuchung unterstreicht die unterschiedlich verwendeten, aber dennoch gemeinsamen stilistischen, narrativen und thematischen Elemente, die sie im Film einsetzen. Im Laufe der Untersuchungen begegnet die Aufrichtigkeit nicht nur als diskursives Phänomen, sondern auch als eine vielseitige kulturelle Praxis. Die Mittel, mit denen die einzelnen Filme versuchen bei den Zuschauern eine emotionale Reaktion hervorzurufen, berechtigen die Einordnung einer solchen ästhetischen Taktik als aufrichtig und ehrlich.

Jahrhunderts auseinanderzusetzen: Darf der Richter im Prozess aufgrund falscher Zeugen wider besseres Wissen einen Unschuldigen zum Tode verurteilen? Ist eine christliche Stadt zur Tötung oder Auslieferung eines Predigers an einen heidnischen Tyrannen berechtigt, wenn davon ihre Existenz abhängt? Muss sich der Prediger von sich aus für das Gemeinwesen opfern? Der Beitrag zeigt, wie neben das „strafrechtliche“ Schuldmodell, wonach der Unschuldige keinen Nachteil verdient und nicht getötet werden darf, in der Spanischen Spätscholastik ein stärker auf Nutzenargumente, insbesondere das Gemeinwohl, abstellendes Utilitätsmodell tritt, das die Tötung des Unschuldigen aus schuldfremden Gründen erlaubt. Damit geht ein Wandel des Staatsverständnisses einher – weg vom Gottesstaat hin zum irdischen Machtstaat, der das Leben seiner Bürger für das Gemeinwesen opfert.

    The CTBT International Monitoring System is to be comprised of 337 facilities located all over the world for the purpose of detecting and locating nuclear test explosions. Major challenges remain, namely the completion of the network where most of the remaining stations have either environmental, logistical and/or political issues to surmont (89% of the stations have already been built) and the sustainment of a reliable and state-of the-art network covering 4 technologies - seismic, infrasound , hydroacoustic and radionuclide. To have a credible and trustworthy verification system ready for entry into force of the Treaty, the CTBTO is protecting and enhancing its investment of its global network of stations and is providing effective data to the International Data Centre (IDC) and Member States. Regarding the protection of the CTBTO's investment and enhanced sustainment of IMS station operations, the IMS Division is enhancing the capabilities of the monitoring system by applying advances in instrumentation and introducing new software applications that are fit for purpose. Some examples are the development of noble gas laboratory systems to process and analyse subsoil samples, development of a mobile noble gas system for onsite inspection purposes, optimization of Beta Gamma detectors for Xenon detection, assessing and improving the efficiency of wind noise reduction systems for infrasound stations, development and testing of infrasound stations with a self-calibrating capability, and research into the use of modular designs for the hydroacoustic network.

    planning services for data centers. This study demonstrates that US American companies will continue to dominate the market for energy efficient servers, whereas German and European manufacturers are well-positioned in the area of cooling, climate control and rack technologies and in the area of comprehensive planning services. There is a significant need for action to unlock potentials for reducing environmental impacts by means of energy efficient data centers and to use the opportunities offered by this future market. This includes in particular improving the information and knowledge transfer to the operators of data centers, e.g. through a best practice brochure on ''energy efficient data centers''. Furthermore, an improvement of the database on the energy consumption and energy efficiency of data centers in Germany and Europe is urgently needed. Sector roadmaps would be an important contribution to developing this future market. The initiation of a milestone project ''Factor 10'' for the worldwide most efficient data center and the development of a concept for periodic energy checks or energy audits for data centers would lead to a more resource efficient ICT sector.

    With infection once again a high priority for the UK National Health Service (NHS), the medical microbiology and infection-control services require increased technology resources and more multidisciplinary staff. Clinical care and health protection need a coordinated network of microbiology services working to consistent standards, provided locally by NHS Trusts and supported by the regional expertise and national reference laboratories of the new Health Protection Agency. Here, I outline my thoughts on the need for these new resources and the ways in which clinical microbiology services in the UK can best meet the demands of the twenty-first century.

    This report examines the past twenty years of energy market events and energy policies to determine what may be useful for the future. The author focuses on two important lessons that should have been learned but which the author feels have been seriously misunderstood. The first is that oil price shocks were a very big and very real problem for oil importing countries, a problem the has not gone away. The second is that automobile fuel economy regulation has worked and worked effectively to reduce oil consumption and the externalities associated with it, and can still work effectively in the future.

    The development of the synchrotron, and later the storage ring, was based upon the electrical technology at the turn of this century, aided by the microwave radar techniques of World War II. This method of acceleration seems to have reached its limit. Even superconductivity is not likely to lead to devices that will satisfy physics needs into the twenty-first century. Unless a new principle for accelerating elementary particles is discovered soon, it is difficult to imagine that high-energy physics will continue to reach out to higher energies and luminosities.

    Some of the achievements of earth observations from past space missions are described. Also discussed are the achievements to be anticipated from currently approved and planned earth observation missions. In looking forward to what the objectives of earth observations from space are expected to be in the future, together with what technology is expected to enable, what the earth observing program will look like during the first part of the twenty-first century is discussed. It is concluded that a key part of this program will be long-term observations holistically viewing the earth system.

    Full Text Available The Surface Enhanced Raman Scattering (SERS effect was observed for the first time in 1974, but it was only considered a new effect three years later, hence, nearly twenty years ago. Since its discovery, a significant amount of investigations have been performed aiming at to clarify the nature of the observed enhancement, to improve the surface stability and to establish applications which nowadays range from the study of biomolecules to catalysis. Some of the more relevant aspects of this effect which have been examined across the last two decades are summarized in this paper which presents the introductory aspects of SERS alongside with several of its applications.

    Full Text Available Introduction: Violent and agitated patients pose a serious challenge for emergency medical services (EMS personnel. Rapid control of these patients is paramount to successful prehospital evaluation and also for the safety of both the patient and crew. Sedation is often required for these patients, but the ideal choice of medication is not clear. The objective is to demonstrate that ketamine, given as a single intramuscular injection for violent and agitated patients, including those with suspected excited delirium syndrome (ExDS, is both safe and effective during the prehospital phase of care, and allows for the rapid sedation and control of this difficult patient population. Methods: We reviewed paramedic run sheets from five different catchment areas in suburban Florida communities. We identified 52 patients as having been given intramuscular ketamine 4mg/kg IM, following a specific protocol devised by the EMS medical director of these jurisdictions, to treat agitated and violent patients, including a subset of which would be expected to suffer from ExDS. Twenty-six of 52 patients were also given parenteral midazolam after medical control was obtained to prevent emergence reactions associated with ketamine. Results: Review of records demonstrated that almost all patients (50/52 were rapidly sedated and in all but three patients no negative side effects were noted during the prehospital care. All patients were subsequently transported to the hospital before ketamine effects wore off. Conclusion: Ketamine may be safely and effectively used by trained paramedics following a specific protocol. The drug provides excellent efficacy and few clinically significant side effects in the prehospital phase of care, making it an attractive choice in those situations requiring rapid and safe sedation especially without intravenous access.

    The aim of the project was to identify areas in households and the tertiary sector in which changes in behaviour could result in energy conservation and thus a reduction of greenhouse gas emissions, and to quantify the potentials for 1995, 2005 and 2020. A second focus was on the analysis and evaluation of programmes and instruments to realise the potentials. With literature evaluation, expert interviews, and a household servey potentials and further technical development have been identified. In sum, behavioural measures can contribute to the CO2 reduction by 64 million tons in 1995 in households and 27 in the commercial sector in which the potential decreases to 18 million tons in 2020 due to the autonomous technical development. Adequate promotion programmes can help to realise 20-30% of the potential by 2020. (orig.) [German] Ziel des Vorhabens war, im Sektor private Haushalte und Kleinverbrauch Bereiche zu identifizieren, in denen Verhaltensaenderungen zur Energieeinsparung fuehren koennen, und diese Potenziale fuer 1995, 2005 und 2020 zu quantifizieren. Darauf aufbauend waren Programme und Instrumente zur Umsetzung aufzuzeigen und zu bewerten. Gestuetzt auf Literaturrecherchen und Expertengespraeche wurden Einzelpotenziale, Rahmenbedingungen, Entwicklungstrends in der Technik und im Ausstattungsgrad ermittelt. Insgesamt koennten Verhaltensmassnahmen im Haushaltssektor die CO2-Emissionen im Basisjahr 1995 um 64 Mio, im Kleinverbrauch um 27 Mio t vermindern. Bis 2020 bleibt dieses Potenzial im Haushaltssektor in etwa gleich. Im Kleinverbrauch sinkt es infolge der autonomen Technikentwicklung auf 18 Mio t ab. Durch geeignete Programme koennen bis 2020 etwa 20-30% des Potenzials erreicht werden. (orig.)

    The United States, like many nations, continues to experience rapid growth in its racial minority population and is projected to attain so-called majority-minority status by 2050. Along with these demographic changes, staggering racial disparities persist in health, wealth, and overall well-being. In this article, we review the social psychological literature on race and race relations, beginning with the seemingly simple question: What is race? Drawing on research from different fields, we forward a model of race as dynamic, malleable, and socially constructed, shifting across time, place, perceiver, and target. We then use classic theoretical perspectives on intergroup relations to frame and then consider new questions regarding contemporary racial dynamics. We next consider research on racial diversity, focusing on its effects during interpersonal encounters and for groups. We close by highlighting emerging topics that should top the research agenda for the social psychology of race and race relations in the twenty-first century.

    2014-05-01

    The effect of large-scale atmospheric pressure changes on regional mean sea level projections in the German Bight in the twenty-first century are considered. A developed statistical model is applied to climate model data of sea level pressure for the twenty-first century to assess the potential contribution of large-scale atmospheric changes to future sea level changes in the German Bight. Using 78 experiments, an ensemble mean of 1.4-cm rise in regional mean sea level is estimated until the end of the twenty-first century. Changes are somewhat higher for realisations of the special report on emission scenarios (SRES) A1B and A2, but generally do not exceed a few centimeters. This is considerably smaller than the changes expected from steric and self-gravitational effects. Large-scale changes in sea level pressure are thus not expected to provide a substantial contribution to twenty-first century sea level changes in the German Bight.

  1. Strategies for Teaching Maritime Archaeology in the Twenty First Century

    Science.gov (United States)

    Staniforth, Mark

    2008-12-01

    Maritime archaeology is a multi-faceted discipline that requires both theoretical learning and practical skills training. In the past most universities have approached the teaching of maritime archaeology as a full-time on-campus activity designed for ‘traditional’ graduate students; primarily those in their early twenties who have recently come from full-time undergraduate study and who are able to study on-campus. The needs of mature-age and other students who work and live in different places (or countries) and therefore cannot attend lectures on a regular basis (or at all) have largely been ignored. This paper provides a case study in the teaching of maritime archaeology from Australia that, in addition to ‘traditional’ on-campus teaching, includes four main components: (1) learning field methods through field schools; (2) skills training through the AIMA/NAS avocational training program; (3) distance learning topics available through CD-ROM and using the Internet; and (4) practicums, internships and fellowships. The author argues that programs to teach maritime archaeology in the twenty first century need to be flexible and to address the diverse needs of students who do not fit the ‘traditional’ model. This involves collaborative partnerships with other universities as well as government underwater cultural heritage management agencies and museums, primarily through field schools, practicums and internships.

    A cooperative project to measure the chemistry and physics of convective storms was conducted during the period 1 May-30 June 1988 in an 80 km x 80 km area of east-central Illinois near Champaign-Urbana. An organization named the Cloud Chemistry and Cloud Physics Organization, or 3CPO, coordinated the project, which was hosted by the Illinois State Water Survey. To achieve the objectives, the following projects were undertaken and are described: a description of the sequential chemistry of rain experiment -- 1988; procedures for the analysis of aqueous hydrogen peroxide in rain samples collected during SECORE-88; preliminary data for SECORE-88; research summary report; a modified successive corrections method that meets statistical goals; dry deposition flux estimates for large-particle elements from dry-bucket measurements; spatial relationships between acid rain, air quality, and visibility data; and synthetic precipitation reference samples. Individual projects are processed separately for the data bases. (CBS)

    The closer the end of coal mining in 2018, the more the issue of groundwater re-emergence in the Ruhr area is also being considered. This is especially the case because currently the subject of restitution and liability issues in the area of contaminated sites of the peaceful use of nuclear energy is discussed. In addition, the companies concerned lost considerable value on the stock market. For this reason, the question of whether the financial provisions in the created foundation are sufficient to shoulder the expected responsibilities and measures also arises with regard to coal mining. The question is which measures are to be taken and where damages can occur. Additional impulses are given by the Meggen judgment of the BVerwG of 18.12.2014, which interpreted the responsibility of the mining companies very widely. In the Rhineland, an earthquake hit 2.4 on 22.12.2015 - probably due to a rise in groundwater around the closed opencast mine Bergheim. All these questions are included in the colloquium on economics and environmental law on 26 January 2016. This also includes experiences and problems from other federal states such as Brandenburg and Saxony.

Zudem verloren die betroffenen Gesellschaften an der Boerse erheblich an Wert. Daher stellt sich auch in Bezug auf den Steinkohlenbergbau die Frage, ob die finanziellen Rueckstellungen in der geschaffenen Stiftung ausreichen, um die zu erwartenden Verantwortlichkeiten und Massnahmen schultern zu koennen. Vorgelagert ist die Frage, welche Massnahmen zu ergreifen sind und wo Schaeden auftreten koennen.

    The U.S. Department of Energy (DOE) has performed a department-wide scoping of its packaging and transportation needs and has arrived at a projection of these needs for well into the twenty-first century. The assessment, known as the Transportation Needs Assessment (TNA) was initiated during August 1994 and completed in December 1994. The TNA will allow DOE to better prepare for changes in its transportation requirements in the future. The TNA focused on projected, quantified shipping needs based on forecasts of inventories of materials which will ultimately require transport by the DOE for storage, treatment and/or disposal. In addition, experts provided input on the growing needs throughout DOE resulting from changes in regulations, in DOE`s mission, and in the sociopolitical structure of the United States. Through the assessment, DOE`s transportation needs have been identified for a time period extending from the present through the first three decades of the twenty-first century. The needs assessment was accomplished in three phases: (1) defining current packaging, shipping, resource utilization, and methods of managing packaging and transportation activities; (2) establishing the inventory of materials which DOE will need to transport on into the next century and scenarios which project when, from where, and to where these materials will need to be transported; and (3) developing requirements and projected changes for DOE to accomplish the necessary transport safely and economically.

    Full Text Available This paper reports the findings of a study developed to evaluate the suitability and potential of Instant Messaging (IM for the Novanet Live Help service. Both IM and the existing commercial Virtual Reference (VR software were offered in tandem for one semester. The services were evaluated through a combination of statistical reports and survey data gathered from both the users and service providers. Comparison of statistics revealed a 44% increase in online sessions, with 22% more sessions received by the IM service. Although users displayed satisfaction with both of the online services, they preferred IM over the VR software. The IM chat widget was reported as the most preferred method for receiving library reference services overall, including face-to-face, telephone and email. Both undergraduate and graduate students preferred the IM service, while faculty and other patron groups did not have a significant enough response rate to assure an accurate measure. After the initial learning curve, service providers preferred delivering online reference by IM over the commercial VR platform. Based on these results, Novanet’s Live Help service will switch to a multi-protocol IM-based service with a chat widget in the fall of 2008.

    Motor vehicles contribute much to urban air pollution. As a result, most governments have enacted emission standards that significantly lower pollutant emission levels from new motor vehicles. For example, vehicles built in the United States emit 95 % fewer pollutants than uncontrolled vehicles when they are new. However, studies indicate that proper maintenance is needed to obtain the full benefit of vehicle emission controls. Furthermore, there is evidence that a significant percentage of the vehicle fleet is not properly maintained. This has led to the creation of motor vehicle Inspection/Maintenance (I/M) Programs. I/M programs inspect vehicles for indications that they are emitting excessive quantities of pollutants. Vehicles that fail the inspection must be repaired in order to comply with program requirements. The first I/M programs were implemented in the United States in the early 1970s. With substantial urging from the federal government, most of the U.S. states with severe air pollution problems have implemented I/M programs. Recently, with the passage of the U.S. Clean Air Act Amendments of 1990, many states have been required to significantly upgrade the performance and coverage of their I/M programs. I/M programs also have been implemented in Europe and recently in Asia. This presentation reviews developments in I/M programs for light-duty gasoline powered vehicles. Developments in I/M programs for diesel powered vehicles are briefly described. (author)

    Full Text Available Bildgebende Verfahren sind eine wichtige Grundlage der Therapieplanung und -kontrolle bei Hirntumoren. Bislang diente hierzu in erster Linie die Größenbeurteilung auf herkömmlichen morphologischen MRT-Aufnahmen. Sowohl zur besseren Therapieplanung und -kontrolle im Rahmen etablierter Therapieschemata als auch zur Evaluation neuer Therapieverfahren ist die Erfassung physiologischer Parameter wie der Perfusion, Diffusion oder Permeabilität mithilfe von MRT und PET eine vielversprechende Entwicklung. Mit der PET und entsprechenden Tracern können zusätzlich auch Targets zur Tumorklassifikation oder gezielten Therapie nachgewiesen werden. Mit der Spektroskopie können für Tumorgewebe typische Metabolite nachgewiesen werden. Bei einigen Tumorentitäten wie den niedergradigen Gliomen zeigten Studien, dass die Perfusionsbildgebung hilfreich zur Planung des weiteren therapeutischen Vorgehens sein kann. Ziel ist, durch eine Kombination geeigneter Verfahren zu einer frühen und treffsicheren Diagnostik beizutragen.

    IM Per is a detached A7 eccentric eclipsing binary star. We have obtained extensive measurements of the light curve (28,225 differential magnitude observations) and radial velocity curve (81 spectroscopic observations) which allow us to fit orbits and determine the absolute properties of the components very accurately: masses of 1.7831 ± 0.0094 and 1.7741 ± 0.0097 solar masses, and radii of 2.409 ± 0.018 and 2.366 ± 0.017 solar radii. The orbital period is 2.25422694(15) days and the eccentricity is 0.0473(26). A faint third component was detected in the analysis of the light curves, and also directly observed in the spectra. The observed rate of apsidal motion is consistent with theory (U = 151.4 ± 8.4 year). We determine a distance to the system of 566 ± 46 pc.

    2011-05-01

    Full Text Available To fully benefit from the all IP convergence, it should be possible for a user not only to access services ubiquitously and at any time, but also to automatically and seamlessly transfer ongoing communication between different devices. This article investigates the problem space of supporting Session Mobility (SM with IMS and the associated issues such as when and how to support dynamic changes in the set of devices through which the user accesses a session. It also investigates how the SM arrival calls should be handled at the network level where they are not considered as ongoing sessions. Hence, we discuss the design options and identify functional blocks needed to support SM. We propose applying priority-based resource allocation approach to guarantee lower blocking probability for ongoing SM arrival calls compared to new arrival calls. Numerical results show that this approach allows achieving such performance for different call arrival rates.

  3. ODE/IM correspondence for the Fateev model

    2013-01-01

    The Fateev model is somewhat special among two-dimensional quantum field theories. For different values of the parameters,it can be reduced to a variety of integrable systems. An incomplete list of the reductions includes O(3) and O(4) non-linear sigma models and their continuous deformations (2D and 3D sausages, anisotropic principal chiral field), the Bukhvostov-Lipatov model, the N=2 supersymmetric sine-Gordon model, as well as the integrable perturbed SU_2(n)\\otimes SU_2(p-2)/SU_2(n+p-2) coset CFT. The model possesses a mysterious symmetry structure of the exceptional quantum superalgebras U_q{\\hat{\\big(D(2|1;\\alpha)}}\\big). In this work, we propose the ODE/IM correspondence between the Fateev model and a certain generalization of the classical problem of constant mean curvature embedding of a thrice-punctured sphere in AdS_3.

    Full Text Available Die ambulante Therapie von Sexualstraftätern auf der Basis einer gerichtlichen Weisung erlangt seit 1998 in Deutschland zunehmende Bedeutung. Dennoch gibt es zu wenig Behandlungsangebote. Das Ziel der Senkung der Rückfallraten kann durch spezifische Verfahren erreicht werden, wie jüngere Metaanalysen zeigten. So genannte Rückfallpräventionsprogramme allein reichen dazu nicht aus, wesentlich ist die Beachtung des Risk-, Need- und Responsivity- Prinzips unter Einbeziehung motivationsfördernder Maßnahmen sowie die Auseinandersetzung mit paraphilen Neigungen. Einzelne Programme werden skizziert. Der Umgang mit Therapie im Spannungsfeld von Gesellschaft und Justiz erfordert ein ständiges Abwägen der Balance zwischen dem Schutzraum der therapeutischen Beziehung und Kontrollaspekten unter Einbeziehung Dritter. Möglichkeiten, dieser Problematik konstruktiv zu begegnen, werden unter Berücksichtigung eigener Erfahrungen dargestellt.

    Full Text Available Knowledge management in organizations, the learning objects paradigm, the advent of a new web generation, and the “Semantic Web” are major actual trends that reveal a potential for a renewed distance learning pedagogy. First and foremost is the use of educational modelling languages and instructional engineering methods to help decide how to aggregate learning objects in learning and knowledge management environments. This article proposes a set of tools under implementation, such as a graphic Learning Design Editor and a delivery system, using learning object repositories to create IMS-LD online environments. We also propose a strategy for the deployment of learning design tools and methods in learning organizations.

  7. Single-molecule studies of the Im7 folding landscape.

    Pugh, Sara D; Gell, Christopher; Smith, D Alastair; Radford, Sheena E; Brockwell, David J

    2010-04-23

    Under appropriate conditions, the four-helical Im7 (immunity protein 7) folds from an ensemble of unfolded conformers to a highly compact native state via an on-pathway intermediate. Here, we investigate the unfolded, intermediate, and native states populated during folding using diffusion single-pair fluorescence resonance energy transfer by measuring the efficiency of energy transfer (or proximity or P ratio) between pairs of fluorophores introduced into the side chains of cysteine residues placed in the center of helices 1 and 4, 1 and 3, or 2 and 4. We show that while the native states of each variant give rise to a single narrow distribution with high P values, the distributions of the intermediates trapped at equilibrium (denoted I(eqm)) are fitted by two Gaussian distributions. Modulation of the folding conditions from those that stabilize the intermediate to those that destabilize the intermediate enabled the distribution of lower P value to be assigned to the population of the unfolded ensemble in equilibrium with the intermediate state. The reduced stability of the I(eqm) variants allowed analysis of the effect of denaturant concentration on the compaction and breadth of the unfolded state ensemble to be quantified from 0 to 6 M urea. Significant compaction is observed as the concentration of urea is decreased in both the presence and absence of sodium sulfate, as previously reported for a variety of proteins. In the presence of Na(2)SO(4) in 0 M urea, the P value of the unfolded state ensemble approaches that of the native state. Concurrent with compaction, the ensemble displays increased peak width of P values, possibly reflecting a reduction in the rate of conformational exchange among iso-energetic unfolded, but compact conformations. The results provide new insights into the initial stages of folding of Im7 and suggest that the unfolded state is highly conformationally constrained at the outset of folding.

    Silvestri, Stefano

    2012-01-01

    Establishing an asbestos ban is not sufficient to achieve effective primary prevention. Twenty years after the Italian asbestos ban, the residual presence of asbestos-containing materials, estimated to be 80 percent of the quantity existing in 1992, may still be the cause of negative effects to the health of workers and the general population. The so called "asbestos way-out" at this rate of cleaning up, roughly 1 percent per year, is too slow, and new policy to re-discuss the entire process is needed. Encouragement of the owners with tax relief when the substitution of the asbestos roofs is performed with photovoltaic panels, as well as reducing the cost of removal planning local landfills may be the keys to accelerate the cleanup process.

    Full Text Available This article explores some of the latest developments in the scholarship on race relations and nationalism that seek to address the impact of globalization and the changed geo-political relations of the first decade of the twenty-first century. New patterns of identification, some of which challenge existing group boundaries and others that reinforce them, can be seen to flow from the effects of global market changes and the political counter-movements against them. The impact of the “war on terrorism”, the limits of the utility of hard power, and the need for new mechanisms of inter-racial and inter-ethnic conflict resolution are evaluated to emphasize the complexity of these group relations in the new world disorder.

    The challenge of providing adequate power to enable world prosperity in the twenty-first century to continue was discussed. It was estimated that by 2050, a prosperous world of 10 billion people will require 60 TWt of thermal power. Conventional power systems will not be able to provide the needed energy because of limited fuels, contamination of the biosphere and costs. A viable, cost effective alternative will be solar energy that is captured in space and from facilities on the Moon, and that is imported to Earth by microwaves. Global electric power systems that use the Moon and deliver 1,000 TWe-Y of energy by 2070 was suggested as the most obvious alternative. Despite the huge initial cost of 20 to 100 trillion dollars, the long-term cost was said to be small compared to terrestrial and Earth-orbital options. 30 refs., 2 figs.

Este trabajo presenta una técnica de interpolación que disminuye eficientemente el ruido impulsivo en imágenes, mediante el uso de interpolante obtenido por funciones de base radial en el marco de la investigación enfocada en el desarrollo de un Sistema de recuperación de imágenes de recursos acuáticos amazónicos. Esta técnica primero etiqueta los píxeles de la imagen que son ruidosos y, mediante la interpolación, genera un valor de reconstrucción de dicho píxel usando sus vecinos. Los resultados obtenidos son comparables y muchas veces mejores que otras técnicas ya publicadas y reconocidas. Según el análisis de resultados, se puede aplicar a imágenes con altas tasas de ruido, manteniendo un bajo error de reconstrucción de los píxeles "ruidosos", así como la calidad visual.Global support radial base functions are effective in eliminating impulsive noise in non-linear processing. This paper introduces an interpolation technique which efficiently reduces image impulsive noise by means of an interpolant obtained through radial base functions. These functions have been used in a research project designed to develop a system for the recovery of images of Amazonian aquatic resources. This technique starts with the tagging by interpolation of noisy image pixels. Thus, a value of reconstruction for the noisy pixels is generated using neighboring pixels. The results obtained with this technique have proved comparable and often better than those obtained with previously known techniques. According to results analysis, this technique can be successfully applied on images with high noise levels. The results are low error in noisy pixel reconstruction and better visual quality.

    Full Text Available Objective: To evaluate the impact of pharmacists, working collaboratively with patients, on blood pressure control, lifestyle goal setting, adherence to antihypertensive therapy, patient knowledge and satisfaction, and modification of cardiovascular risk factors.Methods: Self-declared hypertensive patients met with the pharmacist for blood pressure monitoring, lifestyle goal setting, and education about medications and disease state on four occasions over a 6–month period.Practice innovation: A community pharmacy partnered with an employer wellness plan to provide education and monitoring for patients with hypertension based on home blood pressure readings obtained using monitors that wirelessly transmit information to the pharmacist. Main outcome measure(s: Percentage of patients at blood pressure goal, mean blood pressure, percentage of patients with lifestyle goals, medication adherence, patient knowledge and satisfaction, and modification of cardiovascular risk factors. Results: Patients not at their goal blood pressure at baseline had a significant decrease in blood pressure and a significant increase in achievement of their blood pressure goals. Across the population, no significant changes were seen in the primary outcome, lifestyle goals, medication adherence or modification of cardiovascular risk factors. Patient knowledge increased from baseline and satisfaction with the service was high. Conclusion: Blood pressure control improved in patients not at their treatment goal. All patients increased their knowledge about hypertension and reported high satisfaction with the pharmacy service. Pharmacy services should be offered to patients who are more likely to reap a benefit. Home blood pressure readings are useful to inform clinical decision making and supplement patient consultation within the pharmacy setting.

    2015-07-01

    Full Text Available Im Sinne einer pragmatistischen Perspektive, wie sie zuerst John DEWEY (1987 [1934] in Anschluss an William JAMES formulierte, ist das Religiöse weniger als eine spezifische Art von experience zu verstehen, denn als ein adjustment hin zu einer epistemischen Perspektive, die alle Erfahrungen in einem veränderten Licht erscheinen lässt. Religiosität zielt damit auf ein besonderes Selbst- und Weltverhältnis, in dem die Beziehung zwischen Selbst und Welt aus einer ganzheitlichen Perspektive betrachtet wird. Wie aber können fremde, auf den ersten Blick in ihrer Genese unwahrscheinliche und unter modernen Verhältnissen zudem anzweifelbare religiöse Haltungen und Sinnsysteme etabliert werden? Am Beispiel der im tibetischen Buddhismus verbreiteten Phowa-Meditation des "bewussten Sterbens" wird untersucht, wie für westliche Adept/innen auf den ersten Blick befremdlich und esoterisch anmutende spirituelle Lehren mit zunehmender Praxis an Evidenz und Sinnhaftigkeit gewinnen können, indem sich Gruppenprozesse, Visualisierungen, körperorientierte Übungen und psychisches Erleben zu einem übergreifenden Arrangement verschränken. Die empirische Datengrundlage für die Untersuchung liefern narrative Interviews mit westlich sozialisierten Schüler/innen und Lehrer/innen des Diamantweg-Buddhismus, der derzeit größten buddhistischen Gemeinschaft des tibetischen Buddhismus in Deutschland. Die Auswertung der Interviews erfolgte angelehnt an die dokumentarische Methode, erweitert durch eine Kontexturanalyse, um den Reflexionsverhältnissen gerecht zu werden, die den religiösen Selbst- und Weltbezug aufspannen.

Android, a software platformfrom Google, pioneering in middleware and applications domain of handheld devices does not offersupport for IMS services by design.Motivated by these observations, we present novel scalable architecture to cater IMS basedservices on Android. First, we discuss few related works to investigate and analyze the IMS and the roleof SIP in IMS services. Second, we discuss few characteristics of android architecture and detailconstraints associated with middleware sub-system to cater IMS services. Consequently, we describe theproposed architecture addressing inherent challenges like QoS, Extendibility and Security encounteredwhile offering IMS based services. The architectural framework design reduces time-to-deployment byusing a layered approach encompassing three layers, namely: QoE Engine, Advanced IMS Service Core(A-IMS and Application Services Engine (ASE. The A-IMS core is responsible to provide End-2-Endefficient service delivery of IMS services like VOIP. We point out the benefits of using the ASE andgeneric media management and control interface (GMMCI to ensure smooth and swift portability ontodifferent flavors of android. Finally, we conclude by detailing some use-cases of future IMS services likeVideo Sharing/Video Recording in an on-going Video Telephony Call

    For some years now, Dutch power stations have been confronted in various ways and to an increasing extent with organic substances in the water-steam cycle. It is not yet quite clear how great a direct risk these impurities, in the amounts produced, are posing for the integrity of the water-steam cycle, and whether any damage is likely to occur in the short or long run. In order to counteract this problem, KEMA, on behalf of the Dutch electricity companies, has started a research project which is dealing with organic impurities on two levels. (orig.) [German] Die niederlaendischen Kraftwerke werden seit einigen Jahren auf verschiedene Weise und in zunehmendem Masse mit organischen Substanzen im Wasser-Dampf-Kreislauf konfrontiert. Noch nicht ganz geklaert ist im Moment, wie gross die direkte Gefahr ist, die diese Verunreinigungen bei den auftretenden Mengen fuer die Integritaet des Wasser-Dampf-kreislaufs mit sich bringen bzw. ob ueber kurz oder lang Schaeden zu erwarten sind. Kema hat im Auftrag der niederlaendischen Elektrizitaetsunternehmen ein Forschungsprojekt begonnen, das sich auf zwei Ebenen mit organischen Verunreinigungen beschaeftigt. (orig.)

  12. Twenty Meter Space Telescope Based on Diffractive Fresnel Lens

    Diffractive lenses offer two potential advantages for very large aperture space telescopes; very loose surface-figure tolerances and physical implementation as thin, flat optical elements. In order to actually realize these advantages one must be able to build large diffractive lenses with adequate optical precision and also to compactly stow the lens for launch and then fully deploy it in space. We will discuss the recent fabrication and assembly demonstration of a 5m glass diffractive Fresnel lens at LLNL. Optical performance data from smaller full telescopes with diffractive lens and corrective optics show diffraction limited performance with broad bandwidths. A systems design for a 20m space telescope will be presented. The primary optic can be rolled to fit inside of the standard fairings of the Delta IV vehicle. This configuration has a simple deployment and requires no orbital assembly. A twenty meter visible telescope could have a significant impact in conventional astronomy with eight times the resolution of Hubble and over sixty times the light gathering capacity. If the light scattering is made acceptable, this telescope could also be used in the search for terrestrial planets.

    The historical development of the civil nuclear power generation industry is examined in the light of the need to meet conflicting energy-supply and environmental pressures over recent decades. It is suggested that fission (thermal and fast) reactors will dominate the market up to the period 2010-2030, with fusion being relegated to the latter part of the twenty-first century. A number of issues affecting the use of nuclear electricity generation in Western Europe are considered including its cost, industrial strategy needs, and the public acceptability of nuclear power. The contribution of nuclear power stations to achieving CO2 targets aimed at relieving global warming is discussed in the context of alternative strategies for sustainable development, including renewable energy sources and energy-efficiency measures. Trends in the generation of nuclear electricity from fission reactors are finally considered in terms of the main geopolitical groupings that make up the world in the mid-1990s. Several recent, but somewhat conflicting, forecasts of the role of nuclear power in the fuel mix to about 2020 are reviewed. It is argued that the only major expansion in generating capacity will take place on the Asia-Pacific Rim and not in the developing countries generally. Nevertheless, the global nuclear industry overall will continue to be dominated by a small number of large nuclear electricity generating countries; principally the USA, France and Japan. (UK).

    We obtained time-series radial velocity spectroscopy of twenty cataclysmic variable stars, with the aim of determining orbital periods P_orb. All of the stars reported here prove to have P_orb > 3.5 h. For sixteen of the stars, these are the first available period determinations, and for the remaining four (V709 Cas, AF Cam, V1062 Tau, and RX J2133+51) we use new observations to improve the accuracy of previously-published periods. Most of the targets are dwarf novae, without notable idiosyncracies. Of the remainder, three (V709 Cas, V1062 Tau, and RX J2133+51) are intermediate polars (DQ Her stars); one (IPHAS 0345) is a secondary-dominated system without known outbursts, similar to LY UMa; one (V1059 Sgr) is an old nova; and two others (V478 Her and V1082 Sgr) are long-period novalike variables. The stars with new periods are IPHAS 0345 (0.314 d); V344 Ori (0.234 d); VZ Sex (0.149 d); NSVS 1057+09 (0.376 d); V478 Her (0.629 d); V1059 Sgr (0.286 d); V1082 Sgr (0.868 d); FO Aql (0.217 d); V587 Lyr (0.275 d); ...

  15. New Bachelards?: Reveries, Elements and Twenty-First Century Materialisms

    2012-10-01

    Full Text Available Recent years have seen an infusion of new ideas into material philosophy through the work of the so-called ‘new materialists’. Poignant examples appear within two recent books: the first, Vibrant Matter by Jane Bennett (2010, sets out to “enhance receptivity to the impersonal life that surrounds and infuses us” (2010: 4. The second, Elemental Philosophy by David Macauley (2010, advocates an anamnesis or recollection of the elements as imaginatively dynamic matter. Within his essays on the imagination of matter, Gaston Bachelard outlined an archetypal vision of the elements predicated upon the material imagination. He explored the manner in which the imagination inhabits the world, is triggered by the stimulus of material dynamism, and is formed from a co-constitution of subject and object. This article proposes that recent trends in materialist philosophy – as exemplified by the monographs of Bennett and Macauley – reinforce the ideas of Bachelard and take them in new directions. Bachelard provides us with a compelling argument for the rediscovery of material imagination, whereas New Materialism portrays a vision of matter filled with autonomous dynamism that lends itself to entering into a relationship with this imagination. Consequently, this article proposes that Gaston Bachelard has gained a new relevance as a result of contemporary trends in material philosophy, has taken on new possibilities through recent scholarship, and remains a force within the twenty-first century discursive landscape.

    Full Text Available Monoterpenes, the main constituents of essential oils, are known for their many biological activities. The present work studied the potential biological activity of twenty-seven monoterpenes, including monoterpene hydrocarbons and oxygenated ones, against seed germination and subsequent primary radicle growth of Raphanus sativus L. (radish and Lepidium sativum L. (garden cress, under laboratory conditions. The compounds, belonging to different chemical classes, showed different potency in affecting both parameters evaluated. The assayed compounds demonstrated a good inhibitory activity in a dose-dependent way. In general, radish seed is more sensitive than garden cress and its germination appeares more inhibited by alcohols; at the highest concentration tested, the more active substances were geraniol, borneol, (±-β-citronellol and α-terpineol. Geraniol and carvone inhibited, in a significant way, the germination of garden cress, at the highest concentration tested. Radicle elongation of two test species was inhibited mainly by alcohols and ketones. Carvone inhibited the radicle elongation of both seeds, at almost all concentrations assayed, while 1,8-cineole inhibited their radicle elongation at the lowest concentrations (10−5 M, 10−6 M.

The assayed compounds demonstrated a good inhibitory activity in a dose-dependent way. In general, radish seed is more sensitive than garden cress and its germination appeares more inhibited by alcohols; at the highest concentration tested, the more active substances were geraniol, borneol, (±)-β-citronellol and α-terpineol. Geraniol and carvone inhibited, in a significant way, the germination of garden cress, at the highest concentration tested. Radicle elongation of two test species was inhibited mainly by alcohols and ketones. Carvone inhibited the radicle elongation of both seeds, at almost all concentrations assayed, while 1,8-cineole inhibited their radicle elongation at the lowest concentrations (10(-5) M, 10(-6) M).

    Full Text Available Objective: Sarcoidosis is a multisystemic disease, exact cause of disease is unknown but it is assumed that genetic predisposition and ethnic factors play a role in etiology. Studies related with familial sarcoidosis is limited and only case reports about familial sarcoidosis is available from our country. We aimed to evaluate the prevelance of familial sarcoidosis and clinical findings of cases with familial sarcoidosis. Methods: We retrospectively documented file records of 678 patients diagnosed with sarcoidosis and followed up in outpatient clinic of sarcoidosis from January 1996 to February 2016. 28 familial sarcoidosis cases in 14 families were enrolled into the study. Their demographic findings, family relationship, symptoms, laboratory and pulmonary function test results, radiological apperances, diagnostic methods, treatments were recorded. Results: Twenty-eight sarcoidosis patients out of 678 reported as familial cases, giving a prevelance of familial sarcoidosis as 4%. There were 8 sarcoidosis sib, 4 sarcoidosis mother-child, 1 sarcoidosis father-child and 1 sarcoidosis cousin relationship. Female/male ratio was 1.8, mean age of the study population was 43, most freguent symptoms were cough and dyspnea, stage 2 was mostly seen according to chest X-ray, most common CT appearance was mediastinal lymphadenopathy and mediastinoscopy was the most freguent diagnostic method. Conclusion: This study is important to lead interrogation of family in patients with suspected sarcoidosis and future studies investigating familial aggregation in sarcoidosis.

    We report precise measures of the orbital and superhump period in twenty more dwarf novae. For ten stars, we report new and confirmed spectroscopic periods - signifying the orbital period P_o - as well as the superhump period P_sh. These are GX Cas, HO Del, HS Vir, BC UMa, RZ Leo, KV Dra, KS UMa, TU Crt, QW Ser, and RZ Sge. For the remaining ten, we report a medley of P_o and P_sh measurements from photometry; most are new, with some confirmations of previous values. These are KV And, LL And, WX Cet, MM Hya, AO Oct, V2051 Oph, NY Ser, KK Tel, HV Vir, and RX J1155.4-5641. Periods, as usual, can be measured to high accuracy, and these are of special interest since they carry dynamical information about the binary. We still have not quite learned how to read the music, but a few things are clear. The fractional superhump excess epsilon [=(P_sh-P_o)/P_o] varies smoothly with P_o. The scatter of the points about that smooth curve is quite low, and can be used to limit the intrinsic scatter in M_1, the white dwarf ...

  20. Twenty-second Fungal Genetics Conference - Asilomar, 2003

    The purpose of the Twenty Second Fungal Genetics Conference is to bring together scientists and students who are interested in genetic approaches to studying the biology of filamentous fungi. It is intended to stimulate thinking and discussion in an atmosphere that supports interactions between scientists at different levels and in different disciplines. Topics range from the basic to the applied. Filamentous fungi impact human affairs in many ways. In the environment they are the most important agents of decay and nutrient turnover. They are used extensively in the food industry for the production of food enzymes such as pectinase and food additives such as citric acid. They are used in the production of fermented foods such as alcoholic drinks, bread, cheese, and soy sauce. More than a dozen species of mushrooms are used as foods directly. Many of our most important antibiotics, such as penicillin, cyclosporin, and lovastatin, come from fungi. Fungi also have many negative impacts on human health and economics. Fungi are serious pathogens in immuno-compromised patients. Fungi are the single largest group of plant pathogens and thus a serious limit on crop productivity throughout the world. Many fungi are allergenic, and mold contamination of residences and commercial buildings is now recognized as a serious public health threat. As decomposers, fungi cause extensive damage to just about all natural and synthetic materials.
