description: High-altitude saline lakes (located more than 3000 m a.s.l.) provide multiple environmental extremities for polyextremophilic bacteria. In this study, lake sediment samples from Laguna Santa Rosa and microbial mat samples from the warm water pool of Laguna Verde (Puna de Atacama, Chile) were examined by cultivation and pyrosequencing. The 16S rRNA gene-based identification showed that most of the bacterial isolates belonged to different moderately halophilic Marinobacter species (Proteobacteria). Sample-specific occurrence was characteristic of genera Caenispirillum, Halomonas, Idiomarina, Nitratireductor and Salinarimonas (Proteobacteria), Planococcus, Jeotgalibacillus and Paraliobacillus (Firmicutes), Psychroflexus (Bacteroidetes) and Arthrobacter (Actinobacteria). Using cultivation-independent technique, the benthic communities of both lakes were dominated by sequences related to the phyla Proteobacteria and Bacteroidetes. In addition, representatives of phyla Actinobacteria, Chlorobi, Chloroflexi, Cloacimonetes, Cyanobacteria, Deferribacteres, Deinococcus-Thermus, Firmicutes, Gracilibacteria, Latescibacteria, Lentisphaerae, Parcubacteria, Planctomycetes, Spirochaetae, Tenericutes and Verrucomicrobia were present at least 1% relative abundance. Large differences were explored in the bacterial community composition of the sediment and mat samples at the level of the identified families. It is hypothesized that depending on the type of benthic habitat, different bacteria – involved in the phototrophy based primary production as well as the mainly anaerobic biodegradation of organic materials – can participate in the local carbon, nitrogen, and sulfur cycles.

description: Abstract: To ensure the preservation and restoration of mires and peatlands public funds as well as the willingness of our society are required. In order to inspire people with needed interest, the rational understanding of the necessity for nature conservation, moreover the cognition of the intrinsic values of peatlands have to be stimulated. Against this background, modern environmental education on mires becomes essential, and besides offers also hardly recognized chances of economical improvement. As an example, in economically underdeveloped regions, such as Brandenburg (federal state in north-east Germany), which in contrast has copious cultural and natural environment, sustainable tourism has a lot of growth potential and should be promoted. On this note this article introduces two projects in Brandenburg: first the programme INFORME running at Humboldt-Universität in Berlin and second a mire adventure trail in the natural park Stechlin-Ruppiner Land, being currently under implementation. The article summarizes the gained experiences.
description: Zusammenfassung: Um den Erhalt naturnaher Moore zu sichern bzw. diese wieder neu zu begründen, bedarf es öffentlicher Gelder und des Willens der Gesellschaft. Dieser kann nur entwickelt werden, wenn in den Menschen neben dem verstandesmäßigen Erfassen von Notwendigkeiten auch die Motivation geweckt wird, diese Werte in unserer Landschaft als solche zu begreifen und zu erhalten. Speziell in einer strukturschwachen Region wie Brandenburg, deren Stärke in ihrer kulturellen und naturräumlichen Ausstattung liegt, ist das Entwicklungspotential der Förderung eines naturverträglichen Tourismus zu nutzen. Vor diesem Hintergrund bietet moderne Umweltbildung zum Thema Moore nicht nur eine Verpflichtung, sondern auch eine Chance, die bisher kaum wahrgenommen wird. In diesem Sinne werden zwei Vorhaben im Land Brandenburg vorgestellt: das Projekt INFORME an der Humboldt-Universität zu Berlin und ein sich in Umsetzung befindender Moorerlebnispfad im Naturpark Stechlin-Ruppiner Land. Die gesammelten Erfahrungen werden kurz zusammengefasst.

description: Microbial degradation of organic matter is a key driver of subsurface biogeochemistry. Here, we present a bioenergetics-informed kinetic model for the anaerobic degradation of macromolecular organic matter that accounts for extracellular hydrolysis, fermentation, and respiration. The catabolic energy generated by fermentation and respiration is allocated to biomass growth, production of extracellular hydrolytic enzymes, and cellular maintenance. Microbial cells are assumed to exist in active or dormant states with marked differences in maintenance energy requirements. Dormant cells are further assumed to fulfill their maintenance energy requirements by utilizing their own biomass instead of relying on external substrates. When the catabolic Gibbs energy production for a given functional group of microorganisms exceeds the total maintenance energy requirement of the active cells, biomass growth, re-activation of dormant cells, and production of extracellular hydrolytic enzymes are possible. The latter, in turn, allows the microbial community to access more of the available external organic substrates. In the opposite case, active cells decay or become dormant. We apply the model to simulate the anaerobic degradation of cellulose by a hypothetical microbial community consisting of cellulolytic fermenting bacteria and sulfate-reducing bacteria, under conditions representative of those encountered in water-saturated subsurface environments.

description: We construct a two-dimensional, discrete-time quantum walk exhibiting non-Hermitian skin effects under open-boundary conditions. As a confirmation of the non-Hermitian bulk-boundary correspondence, we show that the emergence of topological edge states are consistent with Floquet winding numbers calculated using a non-Bloch band theory invoking time-dependent generalized Billouin zones. Further, the non-Bloch topological invariants associated with quasienergy bands are captured by a non-Hermitian local Chern marker in real space, defined through local biorthogonal eigen wave functions of the non-unitary Floquet operator. Our work would stimulate further studies of non-Hermitian Floquet topological phases where skin effects play a key role.

description: Precision radial velocity data for HD 208487 has been re-analyzed using a new Bayesian multi-planet Kepler periodogram. The periodgram employs a parallel tempering Markov chain Monte Carlo algorithm with a novel statistical control system. We confirm the previously reported orbit (Tinney et al. 2005) of 130 days. In addition, we conclude there is strong evidence for a second planet with a period of 998 -62 +57 days, an eccentricity of 0.19 -0.18 +0.05, and an M sin i = 0.46 -0.13 +0.05 of Jupiter's mass.

description: Zwischen Gaza und Beer Sheva treten äolische Ablagerungen auf mit küstennahem Sand (Kurkar), landeinwärts sandigem Tonlöß und schließlich Tonlöß. Gemäß der faziellen Anordnung und der Schwermineralassoziation war die eiszeitliche Küstenzone Lieferquelle des äolischen Materials. Es wurde in Zeiten der Meeresregression ausgeweht. In Zeiten der Transgression haben sich makromorphologisch sehr kräftige Böden (Hamra) gebildet, nämlich ein Bodenkomplex, der das letzte Interglazial und das frühe Würm umfaßt, ferner ein „mittelpaläolithischer Boden". Etwas weiter nördlich ist zudem ein „epipaläolithischer Bodenkomplex" vorhanden. Ein Vergleich mit dem Periglazialraum nördlich der Alpen zeigt prinzipiell die nämliche Entwicklung, wobei absolute Datierungen von Höhlensintern und Travertinen ein zeitliches Grundgerüst liefern.

description: This thesis investigates the role of experience and personal qualities in defining a production manager in the performing arts. It examines the roles, backgrounds, and qualities of theatrical production managers by analyzing how non-profit arts organizations describe production management and how production managers describe their jobs and themselves. A definition of production management is created through an analysis of thirty-eight production management job descriptions for non-profit performing arts organizations; a survey of nine directors, designers, technicians, stage managers, and a producer; and interviews with five professional production managers from a presenting house, a producing house, and a university theatre.
Essays on the exchange rate and monetary policy in Nepal
Creators: name: Panday, Anjan
Publisher: name: ProQuest
Year: 2023
Subjects: classificationCode: 38
subject: Economics

description: Nepal has a large and growing trade deficit with India and an overall negative trade balance. Its economy is growing slowly relative to India's, while the exchange rate is pegged with India at a parity that is believed to be overvalued. India is Nepal's largest trading partner, with which it also shares an open order. The peg is considered central to macroeconomic stability and is treated as the monetary policy anchor. Nepal also represents a typical case of a country in which remittances are vital for short-run macroeconomic stability, while they may have adverse consequences for the long-run health of the economy. The three essays in this dissertation are relevant to a broader discussion on the macroeconomic impact of remittances in the context of a low-income country.In the first chapter, I consider possible misalignment of Nepal's real effective exchange rate by estimating a behavioral equilibrium exchange rate using a set of fundamentals for the period 1975--2008. The estimates from the Johansen (1998) cointegrated-VAR model as well as a single equation bounds-testing approach to cointegration suggest that Nepal's trade-weighted real exchange rate was overvalued in the last decade and a half.The question of the efficacy of monetary policy in influencing the exchange rate is analyzed in the second chapter, using a monetary model of exchange market pressure. Applying a recently developed estimation technique, impulse indicator saturation, along with general-to-specific modeling, I find that a contractionary monetary policy results in easing pressure on the exchange rate. The robustness of the results is confirmed using various tests.The final essay entails a comprehensive analysis of economic symmetry between Nepal and India, which is one of the pre-conditions for monetary integration. A two-pronged empirical investigation reveals inconclusive evidence to justify such integration on economic grounds. First, using a three-variable SVAR showed a low and negative correlation in the supply shocks. Decomposing the structural shocks into regional and idiosyncratic components showed a favorable co-movement with the regional element only in Nepal's monetary shock. Second, the business-cycle analysis using state-space models of GDP and its components showed some evidence of co-movement with the regional element in some variables while others showed divergence.

description: Rhombomys opimus sodalis, new subspecies   Elburz Giant Gerbil
TYPE.-No. 88867, Amer. Mus. Nat. Hist.; adult d; Maravih, Incha district; alt. about 2000 feet; collector, G. G. Goodwin, Nov. 15, 1938. The type is a skin and skull in good condition. Besides the type there are 22 topotypes including 12 specimens in spirits and 6 specimens from Dasht, alt. 3200 feet, on the headwaters of the Gurgan River.
 GENERAL CHARACTERS.-A pinkish cinnamon gerbil about the size of R. opimus from the sandy wastes on the northeast shore of the Aral Sea but differing in coloration.
 DESCRIPTION.-Color above in general tone pinkish cinnamon, overlaid with black; the hairs dark neutral gray at base followed by a broad band of light ochraceous buff and tipped with black, darkest on crown of head and rump; sides of body, light buff; upperside of fore and hind feet, ring around eye, and ears, light buff; tail, uniform cinnamon-buff with a crest of black hairs on distal half; under parts buffy white, the light buff of sides extending irregularly over much of under parts; base of hairs dark neutral gray. Skull, massive; front incisors with two grooves, characteristic of genus; similar to R. opimus but interparietal broader and molariform teeth larger.
MEASUREMENTS.-Type (skin measured in the flesh); topotypes (adult e and adult 9) in parentheses. Total length, 320 (354, 300); tail vertebrae, 140 (155, 135); hind foot including claws, 45 (44.6, 43).
SKULL.-Greatest length, 45.9 (44.6, 43); condylo-incisive length, 41 (40.4, 39.1); interorbital constriction, 8 (8, 7.6); zygomatic width, 25.8 (26.7, 25.8); length of nasals, 17.2 (16.7, 16.9); interparietal, length 5.4 (6, 5.1), width 7.9 (8.7, 9.4); bullae 16.3 (16, 15); alveoli of upper molar series, 7.5 (7.4, 7).
 REMARKS.-All the known forms of Rhombomys are closely allied, showing little variation in cranial characters and having a wide range in Central Asia.
 R. o. sodalis requires comparison only with R. o. opimus from the sandy wastes, northeast of the Aral Sea and R. o. fumicolorfrom the Syr-Daria, 35 miles northeast of Kokand. Both forms inhabit low desert areas whereas the new race was taken on the upland plateaus from 2000 to 3000 feet elevation in northeastern Iran where a new geographical race might be expected. Typical R. opimus averages smaller than sodalis and coloration more yellowish. R. o. fumicolor is larger than the Iran race and pelage dark grayish instead of pinkish cinnamon.

description: In the conditions of growing globalization and export-oriented nature of the Polish horticulture systematic studies of the competitive position of horticultural businesses are necessary, including cost competitiveness. The paper presents the vertical and horizontal analysis of the costs in horticultural farms in six EU countries, the largest fruit and vegetable producers. It has been shown that Poland still has a favorable competitive position in terms of costs, but their relatively fast growth and increasing production cost-effectiveness gradually make it lower. Synopsis. W warunkach rosnącej globalizacji i proeksportowego charakteru polskiego ogrodnictwa koniecznym jest systematyczne badanie pozycji konkurencyjnej gospodarstw ogrodniczych, w tym konkurencyjności kosztowej. W pracy dokonano pionowej i poziomej analizy porównawczej kosztów w gospodarstwach ogrodniczych sześciu krajów UE, największych producentów owoców i warzyw. Wykazano, że Polska w dalszym ciągu ma korzystną pozycję konkurencyjną pod względem kosztów, ale ich relatywnie szybki wzrost i zwiększanie się kosztochłonności produkcji stopniowo ją obniża.

Paläolithische Kulturen und Pleistozäne Stratigraphie in Süddeutschland
Creators: name: Müller-Beck, Hansjürgen
Publisher: name: Geozon Science Media
Year: 1957

description: Die paläolithischen Inventare Süddeutschlands können wie folgt stratigraphisch gegliedert werden: 1. Frühpaläolithische Begehung im Ausgang einer längeren altpleistozänen Warmphase, wahrscheinlich unmittelbar vor dem „ältesten Löß" Süddeutschlands. Geröllgeräte von Mauer. 2. Begehung ausgangs der nächstjüngeren Warmzeit. Altertümliche Abschlaginventare des Altpaläolithikums. 3. Begehung in einer interstadialen Schwankung der anschließenden Kaltphase. Etwas entwickeltere Abschlaggeräte mit schwacher Faustkeilkomponente. 4.Begehung kurz vor oder im Beginn des letzten Interglazials. Spuren des Faustkeilschaberkreises. 5. Begehung im oberen Abschnitt der gleichen Wärmeperiode. Mousteroide Artefakte mit beginnender Blattspitzentendenz. 6. Altpaläolithische Stufe (Fortführung der 5. Begehung) im Übergang zur letzten Kaltzeit. Einfache Inventare des Oberen Altpaläolithikums, Altpaläolithikum mit Blattspitzen, altpaläolithische Gruppen mit stark gesteigerten Kratzeranteilen. Haldenstein-klinge als Obergrenze des Altpaläolithikums. 1. Jungpaläolithische Begehung im Bereich und möglicherweise vor der Hauptschwankung der letzten Kaltzeit (Hauptschwankung, weil eine ältere — außerhalb Süddeutschlands belegbare — kleinere Oszillation und zumindest zwei jüngere Schwankungen innerhalb der letzten Kaltphase wahrscheinlich sind). Unteres, dem westlichen Aurignacien I sowie ähnlichen östlichen Einheiten anschließbares Jungpaläolithikum. Fortgesetzte Begehung im Oberen Würm durch verschiedene, überwiegend östlich orientierte jungpaläolithische Gruppen bis ins Spät- und Postglazial und Übergang zum Mesolithikum, ohne ausgeprägte Diskordanz zwischen Jungpaläolithikum und Mesolithikum. Die Einordnung in das allgemeine stratigraphische System des süddeutschen Pleistozäns kann nur mit Vorbehalt und unter Beiziehung einiger terminologischer Hilfsbegriffe durchgeführt werden: Die 1. Begehung steht am Ende einer zeitlich ausgedehnten Warmzeit, die nach unten durch Donau und gegen oben durch die „N"-Kaltzeit abgegrenzt erscheint und die Deckenschotter als „G"- und „M"- Kälteoszillationen unbekannter Größenordnung in sich einschließt. Die 2. Begehung wird dem Ausgang des Steinheimer Interglazials zugeteilt, während die 3., 4. und 5. mit der folgenden „R"- Kaltzeit und dem anschließenden „Stuttgarter Interglazial" in Verbindung stehen. Das restliche Altpaläolithikum sowie das gesamte Jungpaläolithikum gehören dem Würm, das Mesolithikum dem frühen Holozän an.

description: At the low temperatures found in the interior of dense clouds and circumstellar regions, along with H$_2$O and smaller amounts of species such as CO, CO$_2$, or CH$_3$OH, the infrared features of CH$_4$ have been observed on icy dust grains. Ultraviolet (UV) photons induce different processes in ice mantles, affecting the molecular abundances detected in the gas-phase. This work aims to understand the processes that occur in a pure CH$_4$ ice mantle submitted to UV irradiation. We studied photon-induced processes for the different photoproducts arising in the ice upon UV irradiation. Experiments were carried out in ISAC, an ultra-high vacuum chamber equipped with a cryostat and an F-type UV-lamp reproducing the secondary UV-field induced by cosmic rays in dense clouds. Infrared spectroscopy and quadrupole mass spectrometry were used to monitor the solid and gas-phase, respectively, during the formation, irradiation, and warm-up of the ice. Direct photodesorption of pure CH$_4$ was not observed. UV photons form CH$_x\cdot$ and H$\cdot$ radicals, leading to photoproducts such as H$_2$, C$_2$H$_2$, C$_2$H$_6$, and C$_3$H$_8$. Evidence for the photodesorption of C$_2$H$_2$ and photochemidesorption of C$_2$H$_6$ and C$_3$H$_8$ was found, the latter species is so far the largest molecule found to photochemidesorb. $^{13}$CH$_4$ experiments were also carried out to confirm the reliability of these results.

description: Während des Jungpleistozäns (Pinedale) stieß als letztes Glied einer Serie von Vergletscherungen ein großer Gletscher aus der südlichen Absaroka-Range durch das hochgelegene Tal des Yellowstone River in nordwestlicher Richtung in das Seebecken vor. Während des Maximalstandes nahm der Gletscher 6200 km² ein; seine größte Mächtigkeit betrug etwa 925 m, so daß sich die gesamte Eismasse auf etwa 975 km³ belaufen haben dürfte. Das Eis überschritt den Rand des Beckens in allen Richtungen und gelangte in die benachbarten Täler, auf die angrenzenden Plateaus und Gebirgsränder, die ebenfalls Eiskappen aufwiesen. Eine Verzahnung des Hauptgletschers mit den Lokalgletschern ist an mehreren Stellen nachzuweisen. Nach dem Maximum des Vorstoßes taute der Gletscher teilweise ab, um später erneut vorzurücken, jedoch nicht bis zum Maximalstand. Der dann einsetzende Abtauprozeß, der in mehreren Phasen erfolgte, ist durch eine Folge von nicht zusammenhängenden Rückzugsbildungen (Kames-Terrassen, See- und Beckenabsätze) zwischen 280 und 33 m über dem jetzigen Seespiegel (2360 m) markiert. In einer Höhe von 180 m begann sich nordöstlich der abtauenden Eismasse zum ersten Mal ein Ur-Yellowstone-See zu bilden, der sich bei ständig sinkendem Wasserspiegel durch den zurückweichenden Eisrand allmählich in südwestlicher Richtung vergrößerte. Vor etwa 11 000 Jahren, als das Eis vollständig verschwand, bildete sich 21 m über dem heutigen Seespiegel zum ersten Mal ein See mit offener Wasserfläche.

description: Die holozäne Überflutungsebene des Rheins ist ein komplexes sedimentäres System. Die geochronologischen Untersuchungen mittels Optisch Stimulierter Lumineszenz (OSL) und Radiokohlenstoff-Datierungsmethode verbessern das Verständnis der holozänen Entwicklung des Rheinsystems und ermöglichen quantitative Studien zu Aggradationsphasen von Flüssen. Die angewandten Single-Aliquot-Regenerierung (SAR)-Protokolle und die angewandten experimentellen Untersuchungen zur Absicherung der Messparameter lassen erkennen, dass die OSL-Datierungstechnik eine geeignete Datierungsmethode für fluviatile Sedimente aus großen Flusssystemen ist. Eine unvollständige Bleichung der fluviatilen Sedimente vor der Ablagerung scheint für die Sedimente aus Bremgarten nicht so dramatisch zu sein wie ursprünglich vermutet. OSL- und Radiokohlenstoff-Datierungsergebnisse bestätigen eine kurze Periode starker Erosion und Akkumulation im Bereich des Tiefgestades von Bremgarten zwischen 500 und 600 Jahren vor heute. Dieses Zeitfenster korreliert mit dem Beginn der Kleinen Eiszeit um ca. AD 1450. Mehrere schwere Flussüberschwemmungen geschahen in Süddeutschland zwischen AD 1500 und 1750. Diese Überschwemmungsereignisse korrelieren mit dem Zeitfenster der Kleinen Eiszeit, darunter die Zerstörung von Neuenburg im Jahre 1525.

description: In this Colloqium Lecture (by one of the authors (D.S)) a thorough presentation of the authors' research on the subjects, stated in the title, is given. By quite laborious mathematics it is explained how one can handle systems in which each Heisenberg commutation relation is deformed separately. For Hilbert space realizability a detailed determinant computations (extending Zagier's one-parameter formulas) are carried out. The inversion problem of the associated Gram matrices on Fock weight spaces is completely solved (Extended Zagier's conjecture) and a counterexample (for $n=8$) to the original Zagier's conjecture is presented in detail.

description: This study evaluates the impacts of fluoxetine, used (in great amounts) by humans and discarded in natural aquatic environments (natural concentration ranges from 0.03 μg/l to 0.5 μg/l in most of natural aquatic environments in USA and Europe).A 4-day (short-term) and a 35-day (long-term) bioassay using natural concentrations of fluoxetine were conducted beginning with 7-day old guppies, Poecilia reticulata. The long-term, chronic exposure experiment was conducted to observe and compare all themorphological (length, width, and weight) and behavioral effects of fluoxetine on P. reticulata larvae. Results show no lethality from the short-time experiment, but all values from the long-term experiment show significant differences in morphological measurementsbetween control group and experimental groups, where mean values for weight, notochord length and belly width, were significantly lower within the experimental groups. Further, experimental groups showed greater changes in behavioral patterns and mortality rates (long-term). These findings are consistent with previous studies using the same and similar species, showing the detrimental impacts of prolonged fluoxetine exposure.

description: This study evaluates the impacts of fluoxetine, used (in great amounts) by humans and discarded in natural aquatic environments (natural concentration ranges from 0.03 μg/l to 0.5 μg/l in most of natural aquatic environments in USA and Europe).A 4-day (short-term) and a 35-day (long-term) bioassay using natural concentrations of fluoxetine were conducted beginning with 7-day old guppies, Poecilia reticulata. The long-term, chronic exposure experiment was conducted to observe and compare all themorphological (length, width, and weight) and behavioral effects of fluoxetine on P. reticulata larvae. Results show no lethality from the short-time experiment, but all values from the long-term experiment show significant differences in morphological measurementsbetween control group and experimental groups, where mean values for weight, notochord length and belly width, were significantly lower within the experimental groups. Further, experimental groups showed greater changes in behavioral patterns and mortality rates (long-term). These findings are consistent with previous studies using the same and similar species, showing the detrimental impacts of prolonged fluoxetine exposure.
Die pleistozänen Schotter und Moränen zwischen oberem Mindel- und Wertachtal (Bayerisch—Schwaben)

description: Auch in der Region zwischen oberer Mindel und Wertach werden Indizien einer donaueiszeitlichen Vorlandvergletscherung gefunden. Der westliche Lobus des pleistozänen Lechgletschers war während der Donaueiszeit bis in die Gegend von Kaufbeuren vorgestoßen. Diese Tatsache wird durch das Moränenvorkommen bei Bickenried dokumentiert. Moräne und zugehörender Schotter verzahnen sich zwischen Bickenried und Irsee. Das Alter der donaueiszeitlichen Ablagerungen ergibt sich aus ihrer stratigraphischen Beziehung zu den jüngeren Schottern und Moränen. Ein fossiler Boden trennt bei Grub den liegenden Günz-Schotter von der hangenden Mindel-Moräne. Diese Tatsache und die vorliegenden Ergebnisse anderer Autoren aus dem unteren Mindeltal erlauben, das Mindeltal als Stratotypenregion für die Mindeleiszeit vorzuschlagen. Zwischen oberem Mindel- und Wertachtal liegen Schotter und Moränen der Würm-, Riß-, Mindel- und Donaueiszeit vor, es ist nicht möglich die Günzschotter exakt mit Moränen zu verknüpfen.

description: Aus der Schichtfolge von vier Brunnenbohrungen, die im Etschtal im Raum von Trient zur Ausführung gelangten, geht hervor, daß hier nach Rückzug der Würmgletscher im Stau der Schuttkegel von Seitentälern ein postglaziales Seebecken bestand. Die Ergebnisse von geoelektrischen, an den Bohrungen geeichten Tiefensondierungen gestatten, zumindest in großen Zügen, die Rekonstruktion der Morphologie des Grundgebirges im Liegenden der postglazialen Talfüllung sowie die Ermittlung des Höchstbetrages der Taleintiefung; die Felssohle liegt in 267 m unter der jetzigen Talsohle (193 m üb. NN) d. h. 74 m unter dem gegenwärtigen Meeresspiegel. Aus den stratigraphischen, sedimentologischen und geophysikalischen Befunden geht hervor, daß im Quartär, zumindest im Wurm und im Postglazial, kausale Beziehungen zwischen den Meeresspiegelschwankungen und der geomorphologischen Entwicklung des Etschtales, auch im inneralpinen Bereich nördlich von Trient, bestanden.

description: We provide a systematic comparison of two numerical methods to solve the widely used nonlinear Schrödinger equation. The first one is the standard second order split-step (SS2) method based on operator splitting approach. The second one is the Hamiltonian integration method (HIM). It allows the exact conservation of the Hamiltonian at the cost of requiring the implicit time stepping. We found that numerical error for HIM method is systematically smaller than the SS2 solution for the same time step. At the same time, one can take orders of magnitude larger time steps in HIM compared with SS2 still ensuring numerical stability. In contrast, SS2 time step is limited by the numerical stability threshold.

description: This study investigated the developmental process of weak central coherence in preschoolers with autism by examining the longitudinal stability of their cognitive profiles utilizing the Brief IQ subtests of the Leiter-R. It was found that young preschoolers with autism (mean age=41.7 months) did not evidence specific strengths and weaknesses within their cognitive profile, suggesting a flat profile of comparable nonverbal abilities. In contrast, at Time 2 (18 months later), children with autism showed significant relative strengths on Form Completion and significant relative weaknesses on Sequential Order. Findings indicated that an uneven pattern of strengths and weaknesses in cognition found in previous research on individuals with autism, namely strengths in nonverbal perceptual versus nonverbal conceptual skills, which are proxies for WCC, are evident for older preschoolers (mean age= 59.7 months), but not yet present 18 months earlier. The results are interpreted as lending support for an important developmental process occurring over the preschool years for children with autism, which may have implications for intervention.

description: Im nördlichen Siebengebirge bei Bonn wurden drei Kolluvien aus Löß über Anmoor- bis Niedermoorbildungen pollenanalytisch untersucht. Die Pollenzusammensetzung deutet auf stark anthropogen beeinflußte Vegetation hin. Dichte Wälder waren zur Zeit der Vermoorung im Untersuchungsgebiet bereits durch Weidewälder verdrängt. Als Ursache für den Beginn der Erosion und der Kolluvienbildung ist die Umwandlung der Weidewälder in Acker- und intensiver genutzte Weideflächen anzusehen. Durch Pollenfunde von Fagopyrum esculentum (Buchweizen) kann die Kolluvienbildung im Untersuchungsgebiet in die Zeit nach dem 14. Jahrhundert datiert werden. 14C-Untersuchungen der Anmoor- bis Niedermoorbildungen bestätigen diese Ergebnisse.

Year: 2023

description: The excessive rates of incarceration and recidivism in the United States reflect a corrections system largely failing to successfully supervise and transition a growing number of ex-offenders released into the community on probation or parole . Research has identified probation and parole officers as significant factors for reentry success, and has examined the role that they play in the reentry process. This thesis uses frame analysis to explore the question of how community correctional officers form attitudes and opinions of their reentering clients and how those perceptions constrain their supervisory decisions. My research presents an analysis of the primary frames that probation and parole officers use when discussing their clients and when explaining their role in the corrections system.
Detection of man made targets using radar polarimetry

description: Since the late 1970's, various synthetic aperture radar (SAR) satellite missions have provided a valuable source of information about the earth's surface. Providing their own illumination, these sensors generate imagery of our planet 24 hours a day, regardless of cloud cover. Until recently, except for the short term space shuttle SIR-C system, these SAR missions carried single-polarized sensors, meaning that the information extracted from the imagery, and the resulting quality of interpretation, was limited. In 2006 the first of a series of planned satellites carrying fully polarimetric SAR sensors was launched. In polarimetric SAR systems, images can be acquired with horizontal (H) and vertical (V) polarizations of the electric field on both transmission and reception. The resulting multipolarized imagery makes available a higher level of information content for a number of applications, including man made target detection. The potential of polarimetric SAR for man made target detection is investigated in this thesis. In the man made target detection field, the purpose is to differentiate the signature of the targets from those of adjacent natural areas. The most operationally successful application in this field is ship detection, as the sea surface usually forms a quite homogeneous and easily distinguishable clutter. Vegetated surfaces, however, usually constitute a more challenging clutter, as the backscatter levels can be very high and the signatures diverse, often being confused with those of man made targets. A few algorithms have been developed with the purpose of separating the targets from clutter. A methodology that employs the following three algorithms was recently tested in order to discriminate crashed aircraft from the surrounding terrain: Polarimetric Whitening Filter (PWF), Even Bounce Analysis and Cameron Decomposition. In these tests, successful results were achieved when the terrain was composed of a homogeneous field of grass and the targets were crashed airplanes. In this work the same methodology is tested with different man made targets and with different clutters. Also, methodologies involving the use of two other algorithms are tested in order to reduce the false alarm rates. These algorithms are Coherence Test of the Symmetric Scattering Characterization Method (SSCM) and Freeman-Durden Decomposition. The methodologies are applied to three different data sets acquired over different Canadian locations - Ottawa (ON), Gagetown (NB) and Vancouver (BC) - with the CV-580 polarimetric SAR system and the false alarm rates are assessed. Results show that the Coherence Test can lower false alarm rates on high vegetation clutter when applied in combination with other algorithms, while Freeman-Durden Decomposition does not perform effectively in the same experiments.

description: Surface waves propagating in the semi-bounded collisional hot QCD medium (quark-gluon plasma) are considered. To investigate the effect of collisions as damping and non-ideality factor, the longitudinal and transverse dielectric functions of the quark-gluon plasma are used within the Bhatnagar-Gross-Krook (BGK) approach. The results were obtained both analytically and numerically in the long wavelength limit. First of all, collisions lead to smaller values of surface wave frequency and their stronger damping. Secondly, the results show that non-ideality leads to the appearance of a new branch of surface waves compared to the collisionless case. The relevance of the surface excitations (waves) for the QGP realized in experiments is discussed.
