In the southern German city of Stuttgart lives a pious Muslim population that has merged with the local population to create a meaningful shared existence. In this ethnographic account, the author ...introduces and examines the lives of ordinary residents, neighborhoods, and mosque communities to analyze moments and spaces where Muslims and non-Muslims engage with each other and accommodate their respective needs. These accounts show that even in the face of resentment and discrimination, this pious population has indeed become an integral part of the urban community.
Background
Shipwrecks on the Baltic Sea seabed pose a serious threat to the marine environment. Fuel, ammunition and chemicals in their holds can enter the ecosystem at any time, causing an ...ecological disaster. It is known that oil spills from ship accidents can affect life and health of different species of animals, both immediately after catastrophe and for many years thereafter. This article discusses the negative impact of shipwrecks on the ecological status of the Baltic Sea and presents the contamination status of bottom sediment core samples taken in the vicinity of shipwrecks located in the South Baltic,
i.e.
, S/s Stuttgart, t/s Franken, S/T Burgmeister Petersen and m/s Sleipner. It is based on the results of research carried out by the Maritime Institute between 2011 and 2016.
Methods
Core samples were taken by a VKG-2 vibrating probe and analysed towards content of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), total petroleum hydrocarbons (TPHs) and total organic carbon (TOC). Seven PAHs and Seven PCBs were determined using solid phase extraction (SPE) technique followed by gas chromatography-mass spectrometry (GC-MS) detection. In order to determine the concentration of TPH, the SPE technique was applied followed by gas chromatography with flame ionisation detector (GC-FID) analysis. TOC content was established by TOC analyser using infrared detection.
Results
Samples taken in the vicinity of the S/s Stuttgart shipwreck have shown the highest concentrations of all analysed parameters compared to the examined wrecks and significantly differed from the results typical for these areas. This studies have shown that the S/s Stuttgart shipwreck poses a serious threat to the marine environment of Baltic Sea and it is necessary to continue studies in this area and to perform a wider range of analysis.
Previous studies show that direct democracy would enhance satisfaction with democracy. Deeper investigations of this relationship are rare, though. Especially questions regarding the individual ...participation, or the winning and losing of a referendum, as well as the local concern of its result and questions with respect to long-term stability of these effects remain unanswered. In this paper, I close this research gap. Doing so, I analyze pooled cross sectional data from 2011 to 2014 which was gathered in the context of a referendum in the German city Stuttgart. The results show a positive impact on satisfaction with democracy of both, the attendance and the winning of the referendum. These effects are reinforced by a rising local concern. None of the effects show long-term stability. Bisherige Studien zeigen, dass mehr direkte Demokratie zu mehr Demokratiezufriedenheit führt. Jedoch fehlen tief gehende Analysen zu diesem Zusammenhang. So wurden bisher weder der Einfluss der individuellen Teilnahme an einem Referendum auf die Demokratiezufriedenheit untersucht, noch die Rolle, die Gewinn und Verlust und die lokale Betroffenheit in diesem Zusammenhang spielen. Diese Lücken will der Beitrag schließen. Hierzu werden gepoolte Querschnittsdaten analysiert, die von 2011 bis 2014 und im Rahmen der Volksabstimmung ‚Stuttgart 21‘ erhoben wurden. Es zeigen sich positive Effekte der Teilnahme und des Gewinns der Volksabstimmung auf die Demokratiezufriedenheit. Eine höhere lokale Betroffenheit verstärkt dies zusätzlich. Allerdings ist keiner der Effekte zeitlich stabil.
The requirements for hydrological models have increased considerably during the previous decades to cope with the resolution of extensive remotely sensed data sets and a number of demanding ...applications. Existing models exhibit deficiencies such as overparameterization, the lack of an effective technique to integrate the spatial heterogeneity of physiographic characteristics, and the nontransferability of parameters across scales and locations. A multiscale parameter regionalization (MPR) technique is proposed as a way to address these issues simultaneously. Using this technique, parameters at a coarser scale, in which the dominant hydrological processes are represented, are linked with their corresponding ones at a finer resolution in which input data sets are available. The linkage is done with upscaling operators such as the harmonic mean, among others. Parameters at the finer scale are regionalized through nonlinear transfer functions which link basin predictors with global parameters to be determined through calibration. MPR was compared with a standard regionalization (SR) method in which basin predictors instead of model parameters are first aggregated. Both methods were tested in a basin located in Germany using a distributed hydrologic model. Results indicate that MPR is superior to SR in many respects, especially if global parameters are transferred from coarser to finer scales. Furthermore, MPR, as opposed to SR, preserves the spatial variability of state variables and conserves the mass balance with respect to a control scale. Cross‐validation tests indicate that the transferability of the global parameters to ungauged locations is possible.
The Middle Carnian Wet Intermezzo (MCWI) of the Stuttgart Formation (Schilfsandstein) and age-equivalent strata of the northwestern Tethys occurred entirely within equivalents of the upper subzone of ...the
Austrotrachyceras austriacum ammonoid zone of the late Julian. Its duration is estimated to be only about 0.7–0.8
myr. In both the Germanic Basin and the northwestern Tethys, the warm climate during the MCWI was characterized by a rate of precipitation that exceeded somewhat the evaporation but was not so great as to be pluvial. The MCWI was related to the atmospheric circulation of a megamonsoonal system that was characterized by strong, moisture-laden, northwesterly flowing trade winds that rose as they reached the estimated 2000–3000
m high eastern shoulder uplift of a huge rift causing them to drop an extraordinary amount of rain. This eastern shoulder uplift lay within the Caledonides of modern day western Scandinavia. This region only, between 30 and 50°N palaeolatitude, had a truly pluvial climate, and the huge amounts of fresh water dropped there transported large amounts of siliciclastics from this rift-shoulder uplift southward into the Germanic Basin.
Before deposition of the siliciclastics an early Julian eustatic sea-level fall caused widespread erosion in the Germanic Basin. In the later part of late Julian, a transgression from the eastern gates with the concurrent strong fresh water influx from the north flooded the centre of the northern Germanic Basin with a shallow brackish sea in which the Osterhagen Horizon (Basisschichten) of the lower Stuttgart Formation was deposited. In the upper Osterhagen Horizon the salinity rapidly decreased from mesohaline through mio- and oligohaline to fresh water levels. In southern Germany the Basisschichten formed entirely within fresh water or very low salinity brackish environments
. Later, a slight subsidence of the southwestern Germanic Basin shifted the main outflow of fresh water toward the southwestern end of the basin, creating local brackish conditions in the northern marginal part of the northwestern Tethys (e.g. in the Lunz Beds). During this time interval, tidal influence also can be found in the Stuttgart Formation deposited in palaeoestuaries of the southwestern Germanic Basin adjacent to the Tethys. The very strong fresh water influx from the north, however, prevented these estuaries from developing a strongly elevated salt content, so that only fresh water to oligohaline brackish faunas are found there such as the Eberstadt bivalve–conchostracan fauna.
At the base of the Tuvalian, the megamonsoonal system either disintegrated or else the trade winds shifted their principal flow direction. This caused the climate within the Germanic Basin and in the nearby northwestern Tethys Sea to become arid again as it had been before the deposition of the Stuttgart Formation. These changes in the atmospheric circulation patterns also terminated the pluvial climatic regime to the north along the Scandinavian eastern rift-shoulder uplift. This in turn ended the transport of huge amounts of siliciclastics from this region southward into the Germanic Basin and ended the deposition of the Schilfsandstein. After this, the hypersaline sabkha and playa sedimentation of the Weser Formation began, which was accompanied by some minor marine ingressions in the southwestern Germanic Basin.
Dieses Open-Access-Buch beschäftigt sich mit der Zuordnung der Gebrauchsspuren bei jung- und endneolithischen Knochenartefakten zu einem Werkmaterial oder einer Funktion. In der Regel werden ...Knochen-, Geweih- und Zahnartefakte nur typologisch untersucht. Dabei werden Begriffe wie etwa „Meißel“, „Pfriem“, „Ahle“, „Schaber“ aufgrund der Form der Artefakte vergeben, ohne jedoch die tatsächliche Funktion bzw. den Verwendungszweck näher zu untersuchen. Experimentalarchäologische Untersuchungen haben gezeigt, dass es durchaus Unterschiede in den Gebrauchsspuren gibt, die wiederum Rückschlüsse auf den tatsächlichen Gebrauch und das bearbeitete Material ermöglichen. Die bisherigen Experimente haben gezeigt, dass sich die Gebrauchsspuren in drei Gruppen einteilen lassen, die wichtige Hinweise auf die Art der Bewegung oder die Handhabung und damit auf das bearbeitete Material geben. Zudem haben die Untersuchungen von nachgebauten Werkzeugen und Artefakten ergeben, dass die Mikrospuren direkt miteinander verglichen werden können.
Molecular solar‐thermal energy storage systems are based on molecular switches that reversibly convert solar energy into chemical energy. Herein, we report the synthesis, characterization, and ...computational evaluation of a series of low molecular weight (193–260 g mol−1) norbornadiene–quadricyclane systems. The molecules feature cyano acceptor and ethynyl‐substituted aromatic donor groups, leading to a good match with solar irradiation, quantitative photo‐thermal conversion between the norbornadiene and quadricyclane, as well as high energy storage densities (396–629 kJ kg−1). The spectroscopic properties and energy storage capability have been further evaluated through density functional theory calculations, which indicate that the ethynyl moiety plays a critical role in obtaining the high oscillator strengths seen for these molecules.
Molecular solar‐thermal energy storage: A synthetic route to norbornadienes with a cyano acceptor and ethynyl‐substituted aromatic donor groups has been developed. The products have been used in low molecular weight norbornadiene–quadricyclane molecular switches with promising molecular solar energy storage properties (see graphic).
Die Konflikte um das Großprojekt »Stuttgart 21« verdeutlichen exemplarisch, wie Protestbewegungen das postdemokratische Zusammenspiel von Staat und Wirtschaft herausfordern. Bürgerbeteiligung und ...Kostentransparenz sind seither nahezu obligatorisch, dabei hat die Bewegung gegen »S21« ihr eigentliches Ziel, das Bahn- und Immobilienprojekt zu stoppen, verfehlt, trotz scheinbar positiver Ausgangslage. Anhand von Schlüsselereignissen im Konflikt um das Großprojekt rekonstruiert Julia von Staden die Dynamiken und Diskurse dieser sozialen Bewegung. Diese Untersuchung stellt in ihrer Art eine Neuheit in der Protest- und Bewegungsforschung dar und ist gleichzeitig ein Lehrstück für andere soziale Bewegungen.
