Neue Erkenntnisse zur Entstehung pleistozäner Talverfüllungen
Creators: name: Becht, Michael
Publisher: name: Geozon Science Media
Year: 1989

description: Während des Pleistozäns wurden in Seitentälern der nördlichen Kalkvoralpen mächtige Lockersedimente abgelagert. Die Gletscher stießen dabei von den Haupttälern in die Seitentäler vor und schufen dort Sedimentfallen. Die Moränensedimente im Lainbachtal bei Benediktbeuern wurden bisher als Staubeckensedimente angesprochen, die in einen Stausee sedimentiert wurden. Anhand des Vergleiches der spät- und postglazialen Ausräummasse mit der Menge akkumulierter Sedimente in dem Schwemmfächer des Lainbaches konnte diese Vorstellung widerlegt werden. Weitere Untersuchungen zum Rundungsgrad und Kristallingehalt von Geröllen und Auftreten von Schichtung im Lockersediment belegen, daß hier Moränenablagerungen des Ferneises vorliegen. Durch hochglazialen Gletschervorstoß sowie zahlreiche Gletscherstandsschwankungen während des Rückschmelzens wurden im Lainbachtal Verebnungen geschaffen, die heute noch in Resten erhalten sind. Der Verlauf fluvialer Erosion seit dem Spätglazial ist noch nicht ausreichend bekannt. Eine Verstärkung der Abtragung mit den Eingriffen des Menschen in den Naturhaushalt vor allem seit dem Mittelalter scheint dagegen gut belegt.

description: We study the kinetics of domain growth of fluid mixtures quenched from a disordered to a lamellar phase. At low viscosities, in two dimensions, when hydrodynamic modes become important, dynamical scaling is verified in the form $C(\vec k, t) \sim L^α f[(k-k_M)L]$ where $C$ is the structure factor with maximum at $k_M$ and $L$ is a typical length changing from power law to logarithmic growth at late times. The presence of extended defects can explain the behavior of $L$. Three-dimensional simulations confirm that diffuse grain boundaries inhibit complete ordering of lamellae. Applied shear flow alleviates frustration and gives power-law growth at all times.

description: Atoms subject to weak coherent incident light can be treated as coupled classical linear oscillators, supporting subradiant and superradiant collective excitation eigenmodes. We identify the limits of validity of this \emph{linear classical oscillator model} at increasing intensities of the drive by solving the quantum many-body master equation for coherent and incoherent scattering from a chain of trapped atoms. We show that deviations from the linear classical oscillator model depend sensitively on the resonance linewidths $\upsilon_α$ of the collective eigenmodes excited by light, with the intensity at which substantial deviation occurs scaling as a powerlaw of $\upsilon_α$. The linear classical oscillator model then becomes inaccurate at much lower intensities for subradiant collective excitations than superradiant ones, with an example system of seven atoms resulting in critical incident light intensities differing by a factor of 30 between the two cases. By individually exciting eigenmodes we find that this critical intensity has a $\upsilon_α^{2.5}$ scaling for narrower resonances and more strongly interacting systems, while it approaches a $\upsilon_α^3$ scaling for broader resonances and when the dipole-dipole interactions are reduced. The $\upsilon_α^3$ scaling also corresponds to the semiclassical result whereby quantum fluctuations between the atoms have been neglected. We study both the case of perfectly mode-matched drives and the case of standing wave drives, with significant differences between the two cases appearing only at very subradiant modes and positions of Fano resonances.

description: This paper deals with inverse problems subject to imprecise or vague information of some involved data by means of interval-valued functions. To provide interval solutions to the inverse problems we have adopted a perturbed collage-based approach and we have also introduced a numerical procedure by means of the use of interval bases in a sense. To illustrate the results, and as an application, we have studied the Volterra interval-valued integral equation, and provide some computational examples.

description: Die seit dem Jahre 1984 gesammelten Befunde zur Würm-Löß-Gliederung im Raum Regensburg werden mit dem vorliegenden Beitrag anhand ausgewählter Profile zusammenfassend dargestellt und mit den Gliederungen von Brunnacker (1982) und Schellmann (1988) verglichen. Auf der Grundlage von 11 Thermolumineszenz-Datierungen und drei 14C-Datierungen wird eine Korrelation mit der Pedostratigraphie des Würms in Mittel- und Osteuropa diskutiert. Der Bildungszeitraum der „Mosbacher Humuszonen" während des Altwürms ist im Untersuchungsgebiet mit einem TL-Alter von 74 +/- 7,4 ka vor heute im Bereich des humosen Abschnittes der „Basisfließerde" im Sinne von BRUNNACKER (1982) erfaßt. Der Übergang von solifluidaler Umlagerung zu verstärkter Lößsedimentation findet im Raum Regensburg im Verlauf des frühen Mittelwürms um 58 +/- 5 ka vor heute statt. Als „Mittelwürm-Boden" (MW-Boden) wird aus dem Untersuchungsraum ein kräftiger f Bv-Horizont beschrieben, der einer Bodenbildung während des Denekamp-Interstadials zwischen 28 und 30 ka vor heute entspricht, die möglicherweise aber auch noch ältere mittelwürmzeitlich-interstadiale Phasen der Pedogenese einschließt. Der Jungwürmlöß ist im Raum Regensburg durch drei initiale Verbraunungshorizonte (f Cv-Horizonte) und einen Naßboden („N") gegliedert (Abb. 14). Die älteste TL-datierte jungwürmzeitliche Lößakkumulation erfolgte um 25,4 + / —2,4 ka. Ein bereits nach biostratigraphischen Befunden als spätglazial eingestufter sogenannter „Sumpflöß" wurde mit einem TL-Alter von 16,2 + /—1,5 ka datiert.

Aqueous Nanoclusters Govern Ion Partitioning in Dense Polymer Membranes

description: The uptake and sorption of charged molecules by responsive polymer membranes and hydrogels in aqueous solutions is of key importance for the development of soft functional materials. Here we investigate the partitioning of simple monoatomic (Na$^+$, K$^+$, Cs$^+$, Cl$^-$, I$^-$) and one molecular ion (4-nitrophenolate; NP$^-$) within a dense, electroneutral poly($N$-isopropylacrylamide) membrane using explicit-water molecular dynamics simulations. Inside the predominantly hydrophobic environment water distributes in a network of polydisperse water nanoclusters. The average cluster size determines the mean electrostatic self-energy of the simple ions, which preferably reside deeply inside them; we therefore find substantially larger partition ratios $K\simeq\>$10$^{-1}$ than expected from a simple Born picture using a uniform dielectric constant. Despite their irregular shapes we observe that the water clusters possess a universal negative electrostatic potential with respect to their surrounding, as is known for aqueous liquid-vapor interfaces. This potential, which we find concealed in cases of symmetric monoatomic salts, can dramatically impact the transfer free energies of larger charged molecules because of their weak hydration and increased affinity to interfaces. Consequently, and in stark contrast to the simple ions, the molecular ion NP$^-$ can have a partition ratio much larger than unity, $K\simeq\>$10-30 (depending on the cation type) or even $10^3$ in excess of monovalent salt, which explains recent observations of enhanced reaction kinetics of NP$^-$ reduction catalyzed within dense polymer networks. These results also suggest that ionizing a molecule can even enhance the partitioning in a collapsed, rather hydrophobic gel, which strongly challenges the traditional simplistic reasoning.

description: We consider the scattering of dark matter particles from superfluid liquid $^4$He, which has been proposed as a target for their direct detection. Focusing on dark matter masses below ~1 MeV, we demonstrate from sum-rule arguments the importance of the production of single phonons with energies $ω\lesssim 1$ meV. We show further that the anomalous dispersion of phonons in liquid $^4$He at low pressures [i.e., $d^2ω(q)/dq^2>0$, where $q$ and $ω(q)$ are the phonon momentum and energy] has the important consequence that a single phonon will decay over a relatively short distance into a shower of lower energy phonons centered on the direction of the original phonon. Thus the experimental challenge in this regime is to detect a shower of low energy phonons, not just a single phonon. Additional information from the distribution of phonons in such a shower could enhance the determination of the dark matter mass.

description: We study the freeze-in production of Feebly Interacting Massive Particle (FIMP) dark matter candidates through a neutrino portal. We consider a hidden sector comprised of a fermion and a complex scalar, with the lightest one regarded as a FIMP candidate. We implement the Type-I Seesaw mechanism for generating the masses of the Standard Model (SM) neutrinos and consider three heavy neutrinos, responsible for mediating the interactions between the hidden and the SM sectors. We assume that an early matter-dominated era (EMDE) took place for some period between inflation and Big Bang Nucleosynthesis, making the Universe to expand faster than in the standard radiation-dominated era. In this case, the hidden and SM sectors are easily decoupled and larger couplings between FIMPs and SM particles are needed from the relic density constraints. In this context, we discuss the dynamics of dark matter throughout the modified cosmic history, evaluate the relevant constraints of the model and discuss the consequences of the duration of the EMDE for the dark matter production. Finally, we show that if the heavy neutrinos are not part of the thermal bath, this scenario becomes testable through indirect detection searches.

Genese und Stratigraphie periglazialer Deckschichten auf der Hochfläche des Ost-Hunsrücks (Rheinisches Schiefergebirge)

description: Aus den unterdevonischen Schiefern und Sandsteinen des Osthunsrücks bildete sich unter warm-humiden Klimabedingungen des ausgehenden Mesozoikum und Tertiär eine kaolinitische Verwitterungsdecke mit einem bis zu 150 m mächtigen Saprolit. In den Kaltzeiten des Pleistozäns war das Rheinische Schiefergebirge Periglazialgebiet. Als Folge der tektonischen Hebung führte die von den großen Flüssen Rhein und Mosel ausgehende rückschreitende Erosion zur Zerschneidung der Rumpffläche durch Kerbtäler und zu ihrer randlichen Auflösung in Riedel. Kryoklastik, Solifluktion und fluviale Abspülung führten auch in den Plateaulagen zu einer Abtragung der oberen Abschnitte der präpleistozänen Verwitterungsdecke. Über dem mesozoisch-tertiären Saprolit wurden periglaziale Deckschichten abgelagert. In den Plateaulagen und mäßig geneigten Hanglagen der quartären Täler sind drei Schichtkomplexe ausgebildet, die sich schwermineralogisch, petrographisch und morphologisch untergliedern lassen. Die weichen bis mürben Saprolitgesteine gingen durch Frostsprengung und Solifluktion in eine strukturlose lehmige Basisfolge über, die noch frei von lößbürtigen Schwermineralen ist. Ihr Mineralbestand und der Skelettanteil werden von dem Verwitterungsgrad des unterlagernden Saprolits bestimmt. Über der Basisfolge lagert, mit deutlicher Schichtgrenze abgesetzt, eine Mittelfolge aus lößlehmhaltigen Solifluktionsdecken. Ihre mikromorphologischen Merkmale eines reliktischen, periglazial überprägten Bt-Horizonts, der zu einer interglazialen Parabraunerde gehörte, lassen den Schluß zu, daß ein Teil der Lößsedimentation und damit auch die Genese der Basis- und Mittelfolge mindestens in das Rißglazial zu stellen ist. Während des Würms war die flächenhafte Abtragung der Landoberfläche somit nur relativ schwach. Abermals wurde die Mittelfolge durch periglaziale Umlagerungsprozesse und weitere Lößbeimengung überprägt. Den Abschluß der Deckschichtenfolge bildet ein äolisches Decksediment der Jüngeren Tundrenzeit aus Lößlehm mit einem hohen Anteil an Laacher-Bims-Aschen. Auch dieses Substrat wurde in den Hochlagen des Mittelgebirges noch solifluidal verlagert. In den Erosionslagen im Bereich der Talsohle der quartären Täler fehlt die mesozoisch-tertiäre Verwitterungsdecke vollständig. Aus dem freigelegten frischen Schiefer entstand durch Kryoklastik ein grober Frostschutt, der kaum noch solifluidal verfrachtet wurde. Die Feinsubstanz der Schuttdecke resultiert im wesentlichen aus der Einspülung von bimshaltigem Staub im Alleröd und der Jüngeren Tundrenzeit.

description: A combinatorial approach to free probability theory has been developped by Roland Speicher, based on the notion of noncrossing cumulants, a free analogue of the classical theory of cumulants in probability theory. We review this theory, and explain the connections between free probability theory and random matrices. We relate noncrossing cumulants to classical cumulants and also to characters of large symmetric groups. Finally we give applications to the asymptotics of representations of symmetric groups, specifically to the Littlewood-Richardson rule.
Rezente Vergletscherungen in zentraliranischen Hochgebirgen

description: Am Beispiel des Zardeh-Kuh Massivs (4200 m) und des Shir-Kuh Massivs (4070 m) wird die heutige Vergletscherung zentraliranischer Hochgebirge untersucht. In beiden Gebirgsmassiven herrschen vergleichbare klimatische Bedingungen: kalte/feuchte Winter und heiße/ trockene Sommer. Der Zardeh-Kuh auf der Luvseite der Zagros-Ketten erhält jedoch eine etwa viermal höhere Niederschlagsmenge (überwiegend Schnee), als der Shir-Kuh auf der trockenen Leeseite. Dadurch ergibt sich ein charakteristischer steiler Anstieg der rezenten Schneegrenze quer über die Zagros-Ketten von West nach Ost von 4000–4100 m auf 4600–4700 m (Bobek 1937). Als Folge der höheren Niederschläge haben sich im Zardeh-Kuh Massiv mehrere kleine Wandfußgletscher sowie zahlreiche Firnflecken entwickelt, während sich im Shir-Kuh Massiv in vergleichbarer Höhe nur perennierende Firnflecken an einer einzigen Stelle halten können. Diese Firnflek-ken jedoch, wie auch ein neu entdeckter perennierender Firnfleck im Zardeh-Kuh Massiv in nur 2300 m Höhe, geben zu der Vermutung Anlaß, daß die rezente Schneegrenze etwa 200 m unter der von Bobek (1937) und Schweizer (1972) angegebenen Höhe verläuft. Darauf deutet auch das Verhalten des großen Firnflecks im Zardeh-Kuh Massiv in 2300 m Höhe hin, der auf Luftbildern von 1955 noch nicht ausgebildet ist. Seither hat sich hier die Schneegrenze offenbar spürbar abgesenkt.

description: This work presents a new adaptive approach for the numerical simulation of a phase-field model for fractures in nearly incompressible solids. In order to cope with locking effects, we use a recently proposed mixed form where we have a hydro-static pressure as additional unknown besides the displacement field and the phase-field variable. To fulfill the fracture irreversibility constraint, we consider a formulation as a variational inequality in the phase-field variable. For adaptive mesh refinement, we use a recently developed residual-type a posteriori error estimator for the phase-field variational inequality which is efficient and reliable, and robust with respect to the phase-field regularization parameter. The proposed model and the adaptive error-based refinement strategy are demonstrated by means of numerical tests derived from the L-shaped panel test, originally developed for concrete. Here, the Poisson's ratio is changed from the standard setting towards the incompressible limit $ν\to 0.5$.

Da es sich bei den Bildungsbecken dieser Sedimente um Lebensräume mit extremen Umweltsbedingungen handelt, muß auch mit der Möglichkeit gerechnet werden, daß mindestens ein Teil der Fährtenerzeuger nur zeitweilig diese Räume besiedelt hat (z.

description: We perform statistical analyses to study the infall of galaxies onto groups and clusters in the nearby Universe. The study is based on the UZC and SSRS2 group catalogs and peculiar velocity samples. We find a clear signature of infall of galaxies onto groups over a wide range of scales 5 h^{-1} Mpc10^{13} M_{\odot} a larger infall is observed, V_{infall} \simeq 200 km s^{-1}. Similarly, we find that galaxies surrounding groups with L_{g}<10^{15} L_{\odot} have V_{infall} \simeq 100 km s^{-1}, whereas for L_{g}>10^{15} L_{\odot} groups, the amplitude of the galaxy infall can be as large as V_{infall} \simeq 250 km s^{-1}. The observational results are compared with the results obtained from mock group and galaxy samples constructed from numerical simulations, which include galaxy formation through semianalytical models. We obtain a general agreement between the results from the mock catalogs and the observations. The infall of galaxies onto groups is suitably reproduced in the simulations and, as in the observations, larger virial mass and luminosity groups exhibit the largest galaxy infall amplitudes. We derive estimates of the integrated mass overdensities associated with groups by applying linear theory to the infall velocities after correcting for the effects of distance uncertainties obtained using the mock catalogs. The resulting overdensities are consistent with a power law with δ\sim 1 at r \sim 10 h^{-1}Mpc.

description: Over the past three decades, describing the reality surrounding us using the language of complex networks has become very useful and therefore popular. One of the most important features, especially of real networks, is their complexity, which often manifests itself in a fractal or even multifractal structure. As a generalisation of fractal analysis, multifractal analysis of complex networks is a useful tool for the identification and quantitative description of the spatial hierarchy of both theoretical and numerical fractal patterns. Nowadays, there are many methods of multifractal analysis. However, all these methods take into account only the fact of connection between nodes (and eventually the weight of edges) and do not take into account the real positions (coordinates) of nodes in space. However, intuition suggests that the geometry of network nodes' position should have a significant impact on its true fractal structure. Many networks identified in nature (e.g. air connection networks, energy networks, social networks, mountain ridge networks, networks of neurones in the brain, street networks) have their own often unique and characteristic geometry, which is not taken into account in the identification process of multifractality in commonly used methods. In this paper, we propose a multifractal network analysis method that takes into account both connections between nodes and the location coordinates of nodes (network geometry). We show the results for different geometrical variants of the same network and reveal that this method, contrary to the commonly used method, is sensitive to changes in network geometry. We carry out tests for synthetic as well as for real-world networks.

Über Eigenschaften, Aufbau und Bedeutung der Huminstoffe
Qualities, Structure and Meaning of Humic Substances
Creators: name: Ziechmann, Wolfgang
Publisher: name: FID GEO
Year: 1981

description: Es werden die Einteilung, die chemischen und physikalischen Eigenschaften, vor allem aber die verschiedenen Analysenmöglichkeiten der Huminstoffe diskutiert. Danach ist eine eindeutige Einordnung der Huminstoffe in den Humifizierungsprozeß möglich. Mit diesen experimentellen Möglichkeiten sind spezifische und abgestufte Eigenschaften der Huminstoffe zu erkennen, die diese Naturstoffe bei sachgemäßer Gewinnung als unabhängig vom Isolierungsprozeß erscheinen lassen. Schließlich wird auf die vielfältigen Möglichkeiten der Huminstoffe eingegangen, mit Nicht-Huminstoffen zu reagieren.
description: There are discussed the classification, the chemical and physical properties, particularly the different possibilities of analysis of humic substances. Accordingly is given a significant classification of humic substances in the process of humification. With these experimental possibilities are to state specific and differentiated properties of humic substances, which allow to recognize after correct isolation these substances as independent from their isolation. Finally are discussed the manifold possibilities of humic substances to react with other compounds.

description: A lot of attention in the academic and policy debate has been given to the process of transformation of large housing estates in Central and Eastern Europe post 1989. This included debate about their decreasing socio-economic status and the gradual deterioration of housing structures. Nevertheless, the transformation processes in various estates have not necessarily followed the same pattern and some districts, instead of decaying, have continued to grow during the capitalist period. This article discusses the case of one such estate in the city of Łódź in Poland, documents the ‘alternative’ format of transformation and discusses its implications for policymaking.
Paläofluide in störungskontrollierten Bruchsystemen der Aachener Geothermie-Bohrung

description: In der vorliegenden Arbeit werden geologische Prozesse im Untergrund des linksrheinischen Rhenoherzynikums und deren Verhältnis zum regionaltektonischen Rahmen anhand der Proben aus der Aachener Geothermie- Bohrung mit dem Schwerpunkt des Fluid- und Stofftransportes untersucht. Die methodische Vorgehensweise basiert auf einer systematischen und detaillierten Bestandsaufnahme der Paläofluide in Form von Flüssigkeitseinschlüssen an Kernmaterial der Bohrung. Im Aachener Raum wurden Untersuchungen von Flüssigkeitseinschlüssen hauptsächlich an postvariszischen Pb-Zn-Gangvorkommen durchgeführt. Die Homogenisierungstemperaturen (Th) von NaCl-CaCl2-Lösungen unterschiedlicher Salinität liegen zwischen 70°C und maximal 190°C (Redecke 1992, Stroink 1993, Muchez et al. 1994, Glasmacher 1995). Für die tektonischmetallogentische Entwicklung des Rheinischen-Schiefergebirges können generell zwei Fluid-Aktivitätsperioden unterschieden werden (Behr et al. 1993). Die im Zuge der variszischen Gebirgsbildung synkinematische Defluidisierung des Orogenkörpers generierte das Fluid-System der ‚Tectonic Brines‘ (1). Diese sind Na-(K)-Cl-betonte Lösungen geringer Salinität mit CO2, CH4 und N2 sowie durch Th < 350°C gekennzeichnet. Im Gegensatz dazu wurden die meisten postvariszischen Ganglagerstätten des Rheinischen- Schiefergebirges durch ‚Basement Brines‘ (2) gebildet. Diese sind Ca- Na-Cl-Lösungen hoher Salinität mit Th < 250°C (Behr et al. 1993).

Two-dimensional finite element models of convective heat transfer in the upper crust — implications for the interpretation of fission-track data
Creators: name: Timar-Geng, Zoltan

Publisher: name: Universitätsverlag Göttingen
Year: 2006

description: Fission-track (FT) thermochronology is a tool routinely used for studies of surface denudation because of its sensitivity to the low temperatures found in the uppermost part of the crust. FT ages and associated track length distributions are regularly interpreted assuming a steady-state temperature field and only conductive heat transfer. However, application of the method to thermochronological studies based on such interpretations may lead to invalid conclusions, if the temperatures at a certain depth had actually varied with time. For example, the convective transfer of heat by hydrothermal fluids can cause transient thermal events within the upper crust. In particular, fluid circulation along fault zones can result in substantial convective heat transport and cause temperature anomalies in the adjacent rocks (Zuther & Brockamp 1988, Fleming et al. 1998, Lampe & Person 2002, Bächler et al 2003). As a consequence, any refined interpretation of FT data requires a thorough understanding of the upper crustal temperature field and its evolution through time. The main objective of this study is to assess quantitatively how convective heat transport influences the upper crustal temperature field as well as the cooling ages and track length distributions observed in apatite FT data...

Addressing via N-body simulations the distribution of the satellite tidal debris in the Milky Way environment

description: We study the distribution of the Milky Way satellites stellar and dark matter debris. For the first time we address the question of the tidal disruption of satellites in simulations by utilising simultaneously a) a realistic set of orbits extracted from cosmological simulations, b) a three component host galaxy with live halo, disc and bulge components, and c) satellites from hydrodynamical simulations. We analyse the statistical properties of the satellite debris of all massive galaxies reaching the inner Milky Way on a timescale of 2 Gyr. Up to 80$\%$ of the dark matter is stripped from the satellites, while this happens for up to 30$\%$ of their stars. The stellar debris ends mostly in the inner Milky Way halo, whereas the dark matter debris shows a flat mass distribution over the full main halo. The dark matter debris follows a density profile with inner power law index $α_{\rm DM}=-0.66$ and outer index $β_{\rm DM}=2.94$, while for stars $α_{*}=-0.44$ and $β_{*}=6.17$. In the inner 25 kpc, the distribution of the stellar debris is flatter than that of the dark matter debris and the orientations of their short axes differ significantly. Changing the orientation of the stellar disc by 90$^{\rm{o}}$ has only a minor impact on the distribution of the satellite debris. Our results indicate that the dark matter is more easily stripped than stars from the Milky Way satellites. The structure of the debris is dominated by the satellite orbital properties. The radial profiles, the flattening and the orientation of the stellar and dark matter debris are significantly different, which prevents the prediction of the dark matter distribution from the observed stellar component.

Fossil overpressures compartments? A case study from the Eifel area and some general aspects
Creators: name: Hilgers, Christoph

name: Urai, Janos L.
Publisher: name: Universitätsverlag Göttingen
Year: 2006

description: Fluid overpressures are well known from hydrocarbon exploration in many sedimentary basins. They can reach almost lithostatic values, and may cause the fracturing of rock. Fracturing allows the discharge of fluid overpressure, and fluid flows along a hydraulic gradient towards a low pressure reservoir. Different mechanisms may cause the precipitation from the fluid, such as a fluid pressure drop, a variation of temperature at the low pressure reservoir, or a different rock type inducing different Eh-pH conditions. Such precipitates in fractures are called veins, which often display paleo-fluid overpressures in rocks. In this study, we present some results from Devonian clastic sedimentary rocks of the Eifel area. Results are compared with other sedimentary basins to highlight some general aspects.
