description: The Lie algebra $sl(3,\C)$ is considered in the basis of generalized Pauli matrices. Corresponding grading is the Pauli grading here. It is one of the four gradings of the algebra which cannot be further refined. The set $\es$ of 48 contraction equations for 24 contraction parameters is solved. Our main tools are the symmetry group of the Pauli grading of $sl(3,\C)$, which is essentially the finite group $SL(2,\Z_3)$, and the induced symmetry of the system $\es$. A list of all equivalence classes of solutions of the contraction equations is provided. Among the solutions, 175 equivalence classes are non-parametric and 13 solutions depend on one or two continuous parameters, providing a continuum of equivalence classes and subsequently continuum of non-isomorphic Lie algebras. Solutions of the contraction equations of Pauli graded $sl(3,\bC)$ are identified here as specific solvable Lie algebras of dimensions up to 8. Earlier algorithms for identification of Lie algebras, given by their structure constants, had to be made more efficient in order to distinguish non-isomorphic Lie algebras encountered here. Resulting Lie algebras are summarized in tabular form. There are 88 indecomposable solvable Lie algebras of dimension 8, 77 of them being nilpotent. There are 11 infinite sets of parametric Lie algebras which still deserve further study.

description: In a pioneering study of signal design, Marler (Marler 1955 Nature 176, 6–8; Marler 1957 Behav. 11, 13–37) argued that the contrasting acoustic design of hawk (seet) and mobbing alarm calls of European passerines reflected their contrasting function. Hawk alarms were high-frequency tones, warning conspecifics to flee but making localization difficult for predators, while mobbing calls were broadband and harsh, allowing easy localization and approach. Contrasting signal features are also consistent with signal detection theory. Discriminating these calls quickly is critical for survival, because hawk alarms require immediate escape. These signals should therefore be selected to be easy to discriminate, reducing the trade-off between immediate fleeing to hawk alarms and unnecessary fleeing to mobbing alarms. Despite these expectations, hawk and mobbing alarm calls of superb fairy-wrens, Malurus cyaneus, are surprisingly similar, raising the question of discriminability without contextual cues. We synthesized these calls on computer, made intermediates and used playbacks to test whether calls can be discriminated acoustically, and if so by what features. We found that birds used multiple acoustic features when discriminating calls, allowing fast discrimination despite overlap in individual parameters. We speculate that the similarity of fairy-wren alarm calls could enhance detectability of both signals, while multiple subtle acoustic differences reduce a trade-off with discriminability.This article is part of the theme issue ‘Signal detection theory in recognition systems: from evolving models to experimental tests'.

description: The aim of this paper is to compare statistical properties of a bubble period with those of the anti-bubble period in stock markets. We investigate the statistical properties of daily data for the Nikkei 225 index in the 28-year period from January 1975 to April 2003, corresponded to the periods of bubbles and anti-bubbles. We divide the time series into two parts, the period of {\it inflation (or bubbles)} from January 1975 to December 2002 and the period of {\it deflation (or anti-bubbles)} from January 1990 to December 2002. We find that the volatility in the inflationary period is approximated by the $q$-exponential distribution with $ q = 1.14 $ while the volatility distribution in the deflationary period is accurately described by an {\it exponential} distribution, that is, the $q$-exponential distribution with $ q \to 1 $. Our empirical findings suggest that the momentous structural changes have occurred at the beginning of 1990 when the speculative bubble was collapsed in the Japan's stock markets.

description: Abstract: The function of mires as landscape historical archives is differently assessed in the peatland literature. An example of five mires is presented here, which are investigated by stratigraphy, palynology and hydrology. They all are situated close togeteher within a well defined late pleistocene landscape section south of Potsdam. The actual knowledge coming from various disciplines of the geo-, bio- and cultural sciences is combined to show their importance for a specialized mire inventory. A pollen diagram presented here reveals the palaeoecological informations concerning the kettle hole origin and the organogenic accumulation during different developmental phases, including the mire degradation of the last decades. All together those informations can be evaluated for the aims of landscape reconstructions, e.g. vegetation transects and maps of that landscape section during various time slices after the last ice age deglaciation.
description: Zusammenfassung: Die Funktion der Moore als Archive der Landschaftsgeschichte wird in der moor- und torfkundlichen Literatur unterschiedlich gewichtet. Am Beispiel von fünf stratigraphisch, pollenanalytisch und hydrologisch untersuchten Mooren einer geomorphologisch klar definierten Teillandschaft des Potsdamer Raumes wird der aktuelle Kenntnisstand als moorkundliches Inventar unter Berücksichtigung verschiedener geo-, bio- und kulturwissenschaftlicher Disziplinen vorgestellt. Ein Pollendiagramm zeigt den paläoökologischen Informationsgehalt zur Genese der Hohlform, die hydrogenetischen Phasen während der organogenen Akkumulation, die Moordegradation der letzten Jahrzehnte und ihre abschließende Bewertung. Daraus ergeben sich Ansätze einer flächenbezogenen Landschaftsrekonstruktion anhand von Vegetationstransekten und -karten für verschiedene Zeitebenen der mehrtausendjährigen Entwicklung seit dem Ende der letzten Eiszeit.

description: Im Sommer 1994 fuhren 9 Biologen zum Studium unzerstörter Hochmoore nach Estland. Die Exkursion wurde möglich durch die hervorragende Unterstützung des Ökologischen Instituts in Tallinn und dort besonders durch die Biologin Frau Senior Researcher TIIU KOFF. Neben dem eigentlichen Fahrtziel lernten die Teilnehmer auch die Landschaft und die Situation der seit 1991 unabhängigen Republik Estland kennen. Die wesentlichen Exkursionspunkte waren: 1. Im 1971 gegründeten Nationalpark Lahemaa im nördlichen Estland sahen wir das überwiegend unzerstörte Viru-Hochmoor, das über einen Holzsteg zugänglich ist. 2. Nur wenige Kilometer vom Ölschiefer-Abbau-Gebiet bei Kothla-Järve liegt ein Kames-Gebiet mit mehreren vermoorten Senken. Hier studierten wir die Belastungen des Ökosystems durch die Emissionen der nahen Industrie. 3. Das riesige Endla-Naturschutzgebiet hat mehrere konvexe Hochmoore, die durch Bäche und Niedermoore voneinander getrennt sind. Eindrucksvoll sind die zahlreichen parallel zu den Höhenlinien verlaufenden Blänken mit teilweise kleinen runden Inseln darin. 4. Im küstennahen Nigula-Moor erfuhren wir sehr viel über die Hydrologie dieses westlichen, mehr ebenen Hochmoores. Es hat ein Drumlin fast ganz überwachsen. Die dadurch bedingten unterschiedlichen Nährstoffverhältnisse ermöglichen niedermoorartige Vegetationseinheiten mitten im Hochmoor.
description: In the summer of 1994, 9 biologists set out to study some virgin bogs in Estonia. The study trip was made feasible by the generous support of the Ecological Institute of Tallinn, in the person of senior researcher Mrs. TIIU KOFF Apart from the original destination, the participants of the excursion were made acquainted with the Whole region and the situation of the Republic of Estonia which regained independence in 1991. The most essential locations of our studies were: 1. The National Park of Lahemaa in northern Estonia founded in 1971. Here we visited the largely intact bog of Viru which can be reached over a wooden footbridge. 2. Only a few kilometres away from the opencast oil shale mine of Kothla-Järve lies an area of Kames with several boggy depressions where we studied the ecological impact of emissions from the neighbouring industry. 3. The vast nature reservation area of Endla contains several convex-shaped bogs, separated by streams and fens. Most impressive are the numerous pools parallel to the contour lines, partly with small, round islets. 4. In the bog of Nigula not far from the coastline we learned a good deal about the hydrology of this more even westerly bog with a drumlin nearly completely overgrown. The differences in nutrients in the water have affected fen-like areas of vegetation in the midst of this bog.

description: Bodily rhythms such as respiration are increasingly acknowledged to modulate neural oscillations underlying human action, perception, and cognition. Conversely, the link between respiration and aperiodic brain activity – a non-oscillatory reflection of excitation-inhibition (E:I) balance – has remained unstudied. Aiming to disentangle potential respiration-related dynamics of periodic and aperiodic activity, we applied recently developed algorithms of time-resolved parameter estimation to resting-state MEG and EEG data from two labs (total N = 78 participants). We provide evidence that fluctuations of aperiodic brain activity (1/f slope) are phase-locked to the respiratory cycle, which suggests that spontaneous state shifts of excitation-inhibition balance are at least partly influenced by peripheral bodily signals. Moreover, differential temporal dynamics in their coupling to non-oscillatory and oscillatory activity raise the possibility of a functional distinction in the way each component is related to respiration. Our findings highlight the role of respiration as a physiological influence on brain signalling.

description: The modal cut-off is investigated experimentally in a series of high quality non-linear photonic crystal fibers. We demonstrate a suitable measurement technique to determine the cut-off wavelength and verify it by inspecting the near field of the modes that may be excited below and above the cut-off. We observe a double peak structure in the cut-off spectra, which is attributed to a splitting of the higher order modes. The cut-off is measured for seven different fiber geometries with different pitches and relative hole size, and a very good agreement with recent theoretical work is found.

description: Acoustic neutrino detection is a promising approach to instrument the large detector volumes needed for the detection of the small neutrino fluxes expected at ultra-high energies (E > 1 EeV). We report on several studies investigating the feasibility of such an acoustic detector. High-precision lab measurements using laser and proton beams aiming at the verification of the thermo-acoustic model have been performed. Different types of acoustic sensors have been developed and characterized. An autonomous acoustic system, attached to the ANTARES prototype string "Line0", has been deployed and operated successfully at 2400 m depth, allowing for in-situ studies of the acoustic background in the Mediterranean Sea.

description: We explore several types of functional relations on the family of multivariate Tutte polynomials: the Biggs formula and the star-triangle ($Y-Δ$) transformation at the critical point $n=2$. We deduce the theorem of Matiyasevich and its inverse from the Biggs formula, and we apply this relation to construct the recursion on the parameter $n$. We provide two different proofs of the Zamolodchikov tetrahedron equation satisfied by the star-triangle transformation in the case of $n=2$ multivariate Tutte polynomial, we extend the latter to the case of valency 2 points and show that the Biggs formula and the star-triangle transformation commute.

description: Die breite Anwendbarkeit von in-situ produzierten Terrestrischen Kosmogenen Nukliden (TCN) in geologischen Fragestellungen und die damit verbundenen Erfahrungen in der Entwicklung und Eignungsprüfung die im letzten Jahrzehnt erlangt wurden, ermutigen diese Methode auch für archäologische Fragestellungen anzuwenden. In diesem Zusammenhang gibt es ein konkretes Bedürfnis für eine zusätzliche unabhängige Methode der Altersbestimmung jenseits der Grenze von Radiokohlenstoff (~ 40 ka). TCN sind nicht nur in einem Grenzbereich mit einer gewissen Präzision anwendbar, sie sind auch geeignet für die unterschiedlichsten Lithologien. Die Anwendung von TCN in archäologischen Fragestellungen ist relativ einfach: entweder wird der Ansatz der Oberflächendatierung gewählt (Nutzung der Produktion von kosmogenen Nukliden) oder man verwendet den Ansatz der Begrabungsalter (Nutzung des Zerfalls von radioaktiven kosmogenen Nukliden). Für eine erfolgreiche Anwendung der Methode ist jedoch eine enge Zusammenarbeit zwischen Archäologen und TCN Spezialisten notwendig. Eine Expositionszeit zwischen 100 a bis zu 5 Ma einer archäologisch geschaffenen Fläche kann durch Oberflächendatierung bestimmt werden. Der Altersbereich der Begrabungsaltermethode liegt zwischen ~0.1 to 5 Ma. TCN wurden während des letzten Jahrzehnts erfolgreich zur Datierung vieler archäologischer Fragestellungen angewendet und sowohl die Oberflächendatierung als auch Begrabungsaltermethode zeigen ein hohes Potenzial um archäologische Fragestellungen lösen zu können.

description: Single-shot ultrafast absorbance spectroscopy based on the frequency encoding of the kinetics is analyzed theoretically and implemented experimentally. The kinetics are sampled in the frequency domain using linearly chirped, amplified 33 fs FWHM pulses derived from a Ti:sapphire laser. A variable length grating pair compressor is used to achieve the time resolution of 500-1000 channels per a 2-to-160 ps window with sensitivity > 5x10-4. In terms of the acquisition time, FDSS has an advantage over the pump-probe spectroscopy in a situation when the "noise" is dominated by amplitude variations of the signal, due to the pump and flow instabilities. The possibilities of FDSS are illustrated with the kinetics obtained in multiphoton ionization of water and aqueous iodide and one-photon excitation of polycrystalline ZnSe and thin-film amorphous Si:H. Unlike other "single-shot" techniques, FDSS can be implemented for fluid samples flowing in a high-speed jet and for thin solid samples that exhibit interference fringes; no a priori knowledge of the excitation profile of the pump across the beam is needed. Another advantage is that due to the interference of quasimonochromatic components of the chirped probe pulse, an oscillation pattern near the origin of the FDSS kinetics emerges. This pattern is unique and can be used to determine the complex dielectric function of the photogenerated species.

description: The ball deep rolling process is used to improve the surface properties of the workpiece. In this research, the optimum state was determined using the design of the experiment to improve the properties including optimum hardness and roughness. It was determined 3 passes and the type of traditionally and ultrasonic process and proposed regression model at the speed of 1000mm/min. In this case, it showed the hardness of 131 micro vickers and also determined minimum roughness in the mean roughness of 0.179 microns and the maximum roughness of 1.01 microns. The microstructure and tensile tests have been investigated in the optimal sample, compared to the surface topographic reference sample. The microstructure has been shown the decreases from about 30-50 microns to about 300 nanometers in thickness at about 50 microns below the surface by scanning electron microscopy. The tensile stress and percentage increase in length were determined by 10% and 29% increase, respectively by the tensile strength test. Topography has also shown the reduction of roughness by 40%. The hardness of the subsurface was studied in the thickness of the workpiece and it was compared to the same traditional and modern optimum specimen. The result showed the effect of increasing the hardness due to the of the structure fracture and strain rate.

description: A full performance analysis of the widely linear (WL) minimum variance distortionless response (MVDR) beamformer is introduced. While the WL MVDR is known to outperform its strictly linear counterpart, the Capon beamformer, for noncircular complex signals, the existing approaches provide limited physical insights, since they explicitly or implicitly omit the complementary second-order (SO) statistics of the output interferences and noise (IN). To this end, we exploit the full SO statistics of the output IN to introduce a full SO performance analysis framework for the WL MVDR beamformer. This makes it possible to separate the overall signal-to-interference plus noise ratio (SINR) gain of the WL MVDR beamformer w.r.t. the Capon one into the individual contributions along the in-phase (I) and quadrature (Q) channels. Next, by considering the reception of the unknown signal of interest (SOI) corrupted by an arbitrary number of orthogonal noncircular interferences, we further unveil the distribution of SINR gains in both the I and Q channels, and show that in almost all the spatial cases, these performance advantages are more pronounced when the SO noncircularity rate of the interferences increases. Illustrative numerical simulations are provided to support the theoretical results.

description: Screening, monitoring, and host-parasite interaction studies were conducted to evaluate the response of selected herbs to the most common root-knot nematodes in Florida. Basil (Ocimum basilicum), borage (Borago officinalis), oregano (Origanum vulgare), lavender fLavendula spica), rosemary (Rosamarinus officinalis), pot marjoram (Q. hortensis), sage (Salvia officinalis), sweet marjoram (0. maiorana), summer savory (Satureja hortensis) and winter savory (Satureia montana), seedlings were inoculated with Meloidogyne arenaria race 1, M. incognita races 1 and 3, and M. javanica. Results from our screening study shows that basil, sage, summer savory, lavender, and rosemary were susceptible, whereas oregano, pot marjoram and sweet marjoram were resistant to Meloidoayne spp. tested. Root-knot was the most common nematode and the one that increased the most on basil, sage and oregano in a Florida field. Most nematodes increased as the season progressed and decreased in the winter. Meloidogyne arenaria race 1 penetrated and established a feeding site in oregano roots. Hypertrophy was observed, hyperplasia limited, mature females were found in and out of the root.

description: Core-collapse supernovae are among the most energetic explosions in the universe marking the catastrophic end of massive stars. In spite of rigorous studies for several decades, we still don't understand the explosion mechanism completely. Since they are related to many astrophysical phenomena such as nucleosynthesis, gamma-ray bursts and acceleration of cosmic rays, understanding of their physics has been of wide interest to the astrophysical community. In this article, we review recent progress in the study of core-collapse supernovae focusing on the explosion mechanism, supernova neutrinos, and the gravitational waves. As for the explosion mechanism, we present a review paying particular attention to the roles of multidimensional aspects, such as convection, rotation, and magnetic fields, on the neutrino heating mechanism. Next, we discuss supernova neutrinos, which is a powerful tool to probe not only deep inside of the supernovae but also intrinsic properties of neutrinos. For this purpose, it is necessary to understand neutrino oscillation which has been established recently by a lot of experiments. Gravitational astronomy is now also becoming reality. We present an extensive review on the physical foundations and the emission mechanism of gravitational waves in detail, and discuss the possibility of their detections.

description: Vulkanische Ereignisse des mittleren und oberen Quartär sind schwer zu datieren, insbesondere, wenn geeignete Minerale für eine 40Ar/39Ar-Datierung fehlen. Mit diesem Artikel werden erste Tests einer neuen Anwendungsmöglichkeit der TL-Datierung an Maar-Tephra und Xenolithen präsentiert, um derartige Eruptionsvorgänge zu datieren. Hierbei wird berücksichtigt, dass ein Rückstellen des latenten geologischen TL-Signals der Gesteinsfragmente während des Eruptionsvorganges eventuell nur unvollständig erfolgte. Aus diesem Grund wurde die „Partial heat- longest plateau-Technik (PHLP) entwickelt, um genau diesem Problem Rechnung zu tragen. Die neu entwickelte Technik kann helfen, eine Überschätzung von TL-Datierungen infolge der unvollständigen Rücksetzung des TL-Signals zu vermeiden. Dies wird für vulkanische Ablagerungen im Eifel-Vulkanfeld demonstriert, die eine Zeitspanne von 11 bis 300 ka umfassen. Obwohl das Problem starken anomalen Ausheilens des TL Signals vulkanischer Feldspäte und anderer vulkanischer Minerale umgangen wurde, existiert immer noch das Problem einer Unterschätzung geologischer Alter als Folge eines langfristigen anomalen Ausheilens im TL Signal. Die orange-roten TL-Emissionen (RTL) reiner feinkörniger Quarzproben aus Xenolithen wurden an zwei Proben getestet. Dieser Datierungsansatz verlangt jedoch noch weitere systematische Untersuchungen.

Creators: name: Ling, Henry Ho-Kong
Publisher: name: University of British Columbia
Year: 2011

description: This thesis focuses on understanding how general coordinate invariance can be incorporated into effective actions for systems of many D0-branes coupled to bulk supergravity fields. We present progress in two special cases. First, we discuss the implementation of covariance under arbitrary spatial diffeomorphisms. A method of constructing actions with manifest covariance under these diffeomorphisms is developed. While the matrix D0-branes coordinates transform in a complicated manner under spatial diffeomorphisms, we find that it is possible to replace these with matrix-valued fields in space with a simple vector transformation law. Using this vector field, we define a distribution function that serves as a matrix generalization of the delta function, and which describes the location of the D0-branes. The covariant Lagrangians then take the form of an integral over space of a scalar built from the various fields times the matrix distribution function. Next, we approach the problem of implementing covariance under coordinate transformations that mix the space and time directions. As a first step towards understanding this problem, we consider in detail the simpler case of incorporating Poincaré invariance into actions for multiple D0-branes in Minkowski space. We find evidence for a non-trivial Lorentz transformation rule for the matrix D0-brane coordinates by using the Poincaré algebra as a guiding consistency condition. We determine the necessary conditions that must be satisfied by the leading term of any Poincaré invariant action, and find an implicit method of constructing a Poincaré invariant completion of any such leading term. The approach is based on using matrix-valued Lorentz covariant fields defined on space-time, built from the matrix D0-brane coordinates.
Afraid to feel good: Is fear of emotion associated with creative problem solving?
Creators: name: Mullarkey, Michael
Publisher: name: American University
Year: 2023

description: Previous literature indicates that increased positive affect leads to greater creative problem solving ability. However, high fear of positive emotion (FOPE) individuals may not capitalize on positive mood inducing situations either because they resist the induction of positive mood or have their positive feelings blunted by the simultaneous experience of fear/anxiety. Experiencing less positive affect than low FOPE individuals could lead to inferior performance on creative problem solving tasks following a positive mood induction. Participants had their FOPE, neuroticism, and pre-induction mood assessed, underwent either a positive or neutral mood induction, and took tests of two domains of creative problem solving, divergent thinking and relational thinking. The hypotheses of the study were not confirmed. High FOPE participants exhibited greater residual positive affect post-induction than low FOPE participants, and there was no relationship between positive affect and creative problem solving in the sample. Potential explanations for these unexpected results are discussed.

title: Christiaan Huygens: a foreign inventor in the Court of Louis XIV, his role as a forerunner of mechanical engineering
Creators: name: Marconell, Maria Helena
Publisher: name: The Open University
Year: 1996

description: The aim of this thesis has been to argue, on the basis of primary sources, that Huygens was a pioneer in the field of mechanical engineering. He fits the definition of a mechanical engineer as somebody who develops a novel invention either empirically or theoretically, using known mechanical theories. In the same way, a new invention may come about through transforming an existing machine or instrument thus revolutionizing any future versions of it. Huygens did both he applied a pendulum to existing clocks and transformed the making of precision instruments from that moment onwards. The first chapter of the thesis presents Huygens' works on pendulum clocks and marine clocks. The second chapter is dedicated to Huygens' research and designs of the air pump and linking with the third chapter on matter theory. The fourth chapter focuses on Huygens' designs of various instruments (the telescope, the microscope, the level, the planetarium and others). The final chapter depicts Huygens in the societies in which he lived. Huygens was a pioneer of mechanical engineering because he presented a complete work on mechanics to explain instruments, 'automata', by mathematical axioms and laws. Furthermore, he developed a methodology for improving instruments and machines based on searching for the best materials to obtain the best working models. The Horologium Oscillatorium of 1673, was a textbook, which inspired others to continue a tradition of mechanics for the mechanical engineer. With geometrical ratios he was able to show the applicability of technology in everyday life. Therefore, Huygens took the foundations of mechanics further than his contemporaries did. The geometry he used was the basis, which could simplify and give a quantitative measure of nature and of any man-made instruments alike.

description: We address the long-standing unresolved problem concerning the V-parameter in a photonic crystal fiber (PCF). Formulate the parameter appropriate for a core-defect in a periodic structure we argue that the multi-mode cut-off occurs at a wavelength lambda* which satisfies V_PCF(lambda*)=pi. Comparing to numerics and recent cut-off calculations we confirm this result.

description: Mobile Id approach provides a contactless and secure identification process. Standardization towards a common scheme is important to ensure wide-spread adoption through cross-country and cross-region interoperability. Therefore mobile identification has seen enormous attention both by platform vendors and researchers.
 In this work we discuss a novel mobile identification approach that is based on oblivious identity to ensure improved privacy protection and identification data at rest protection. The mobile identification approach addresses the development of the interfaces to connect users' identities to their real-world physical identities by integrating with officially issued eIDs through bridging with eIDAS, STORK, or electronic driving licenses.

description: Acoustics loads are rocket design constraints which push researches and engineers to invest efforts in the aeroacoustics phenomena which is present on launch vehicles. Therefore, an in-house computational fluid dynamics tool is developed in order to reproduce high-fidelity results of supersonic jet flows for aeroacoustic analogy applications. The solver is written using the large eddy simulation formulation that is discretized using a finite-difference approach and an explicit time integration. Numerical simulations of supersonic jet flows are very expensive and demand efficient high-performance computing. Therefore, non-blocking message passage interface protocols and parallel input/output features are implemented into the code in order to perform simulations which demand up to one billion degrees of freedom. The present work evaluates the parallel efficiency of the solver when running on a supercomputer with a maximum theoretical peak of 127.4 TFLOPS. Speedup curves are generated using nine different workloads. Moreover, the validation results of a realistic flow condition are also presented in the current work.

description: Powdery mildew (Erysiphe cichoracearum) limits pumpkin (Cucurbita moschata) production in Puerto Rico and other areas of the Caribbean. In order to effectively use half-sib family recurrent selection to develop polygenic mildew resistance we tested various inoculation methods to determine which method can best be used to quantify small differences in resistance. Dusting leaves using infected plant tissue was a fast and effective method that would be useful in a screening program where many genotypes need t4o be evaluated but where resistance need not be quantified. Spraying with a 1 x 10 spores/cc triton suspension was an efficient method for a recurrent selection program where small differences in resistance among families must be determined.
Geomorphologie der alpinen Stufe des Chirripó in Costa Rica

description: Im Relief der alpinen Stufe des Chirripó in Costa Rica sind über der heutigen Waldgrenze bei 3400 m Höhe drei Reliefgenerationen nachzuweisen. Die erste ist vorkaltzeitlich. In ihr wurden die Talzüge und der Verlauf der Wasserscheiden festgelegt. Die zweite ist kaltzeitlich. In ihr wurde das Relief am stärksten geprägt. Kargletscher mit Zungen in den Tälern vertieften und weiteten in allen Richtungen die Talschlüsse und Oberläufe der Täler. Einige während dieser Zeit entstandene Karlinge, Kare, Moränen und Rundhöcker wurden nach der Vereisung durch Periglazialprozesse in den Teilen überprägt, wo eine Schuttauflage vorhanden war. Die dritte Reliefgeneration wird durch das heutige Prozeßgefüge bestimmt. Es ist nur schwach entwickelt; die Formen verändern sich langsam. Lediglich leichte Nachtfröste, ausschließlich episodisch oberflächlich abfließendes Regenwasser und kleine Verwitterungsgeschwindigkeiten wirken nur langsam auf das Relief ein. Tiefer gelegene Bergstufen Costa Ricas sind geomorphologisch wesentlich aktiver. Die glazial entstandenen Formen blieben auch wesentlich besser erhalten als in höher aufragenden tropischen Gebirgen oder in den Hochgebirgsketten der gemäßigten Breiten. So hat sich hier eine vor allem kaltzeitlich gestaltete Bühne erhalten können — die einzige in Zentralamerika.
