description: Σκοπός της διατριβής ήταν η μελέτη του νομικού φαινομένου του συμψηφισμού στις επιμέρους έννομες τάξεις και ιδίως σε διακοινοτικό επίπεδο, τόσο κατά τη φερεγγυότητα των μερών, όσο και κατά την αφερεγγυότητα ενός ή και των δύο των μερών. Η θεώρηση της λειτουργίας, της νομικής μορφής, του τρόπου άσκησής και των έννομων αποτελεσμάτων του συμψηφισμού δεν είναι ενιαίος σε διακοινοτικό επίπεδο. Μελετάται η διαφορετική αντιμετώπιση του συμψηφισμού μεταξύ των δυο μεγάλων οικογενειών δικαίων, των ηπειρωτικών δηλαδή και των αγγλοσαξονικών, τόσο κατά το στάδιο της φερεγγυότητας όσο και της αφερεγγυότητας των μερών. Περιγράφεται διεξοδικότερα η λειτουργία και οι προϋποθέσεις συμψηφισμού κατά το ελληνικό δίκαιο, ως χαρακτηριστικού δικαίου ενταγμένου στην ομάδα των ηπειρωτικών δικαίων, κυρίως κατά την φερεγγυότητα των μερών, όσο και όταν για το ένα από τα δύο έχει εκκινηθεί η πτωχευτική διαδικασία. Περαιτέρω αναλύονται συνοπτικά τα άρθρα του Κανονισμού 1346/2000 του Ευρωπαϊκού Συμβουλίου περί των διαδικασιών αφερεγγυότητας. Ειδικότερα εξετάζεται το ζήτημα του συμψηφισμού όταν εκκινηθεί μια διαδικασία αφερεγγυότητας που υπάγεται στο πεδίο εφαρμογής του Κανονισμού, με έμφαση στο εφαρμοστέο επί της έννομης σχέσης του συμψηφισμού δίκαιο.
description: Present thesis’ goal was to set a closer look on the right to set off between both solvent parties and at the incolvency of one. For set off’s legal function, its legal form, the exercise of the right to set off, or its legal effects there is no singlehand treatment throughout european legal systems. Moreover the present thesis examines the differencies in the addressing of set off between the 2 major law families, ie the continental law systems and the common law system, either when parties are solvent or when an incolvency proceeding has commenced against one of them. In particular, there’s a somehwat deep examination of the role of set off in the greek legal system, as member of the continental legal family. In addition to the latter, brief definitions to the articles of the 1346/2000 Regulation of the Europian Council applying to incolvency preceedings are provided. More importantly summarized is the question of the function of the set off according to the Regulation, with empasis on the law applicable.

description: We propose a modified version of the Horowitz-Maldacena final-state boundary condition based upon a matter-radiation thermalization hypothesis on the Black Hole interior, which translates into a particular entangled state with thermal Schmidt coefficients. We investigate the consequences of this proposal for matter entering the horizon, as described by a Canonical density matrix characterized by the matter temperature $T$. The emitted radiation is explicitly calculated and is shown to follow a thermal spectrum with an effective temperature $T_{eff}$. We analyse the evaporation process in the quasi-static approximation, highlighting important differences in the late stages with respect to the usual semiclassical evolution, and calculate the fidelity of the emitted Hawking radiation relative to the infalling matter.

description: Aim of present postgraduate thesis was the study and presentation of the claim of compensation in the event offence of rights in intangible goods of industrial property (name, signal, discreet title, invention etc). Initially we presented the claim of compensation in the discreet traits of essential system and we analyzed its’ conditions that are the same for the every intangible good. More specifically the conditions of claim of compensation, that should aid in any case, are the illegal offence, the culpability, the damage and the causal affinity between the damage and the legal reason of responsibility. Afterwards we analyzed the claim of compensation in the event offence of signal, and in the end we were reported in the protection, via an action of compensation, of the invention and more specifically of the patent. Another subject that we mentioned was the difficulty of determination of compensation and its’ way of calculation, while we examined the triple way of calculation, that it is used for calculating the compensation. Finally, particular attention happened the analysis of Directive 2004/48/EC, the incorporation in our national right with the N. 3966/2011 but also the problems that this incorporation has created.

description: The long-term prospect of building a hadron collider around the circumference of a great circle of the Moon is sketched. A Circular Collider on the Moon (CCM) of $\sim$11000 km in circumference could reach a proton-proton center-of-mass collision energy of 14 PeV -- a thousand times higher than the Large Hadron Collider at CERN -- optimistically assuming a dipole magnetic field of 20 T. Several aspects of such a project are presented, including siting, construction, availability of necessary materials on the Moon, and powering, as well as a discussion of future studies and further information needed to determine the more concrete feasibility of each. Machine parameters and vacuum requirements are explored, and an injection scheme is delineated. Other unknowns are set down. Due to the strong interest from multiple organizations in establishing a permanent Moon presence, a CCM could be the (next-to-) next-to-next-generation discovery machine for high-energy particle physics and a natural successor to next-generation machines, such as the proposed Future Circular Collider at CERN or a Super Proton-Proton Collider in China, and other future machines, such as a Collider in the Sea, in the Gulf of Mexico. A CCM would serve as an important stepping stone towards a Planck-scale collider sited in our Solar System.

description: The recent experiment by Y. Shin \emph{et al.} [Phys. Rev. Lett. \textbf{93}, 160406 (2004)] on the decay of a doubly quantized vortex imprinted in $^{23}% $Na condensates is analyzed by numerically solving the Gross-Pitaevskii equation. Our results, which are in very good quantitative agreement with the experiment, demonstrate that the vortex decay is mainly a consequence of dynamical instability. Despite apparent contradictions, the local density approach is consistent with the experimental results. The monotonic increase observed in the vortex lifetimes is a consequence of the fact that, for large condensates, the measured lifetimes incorporate the time it takes for the initial perturbation to reach the central slice. When considered locally, the splitting occurs approximately at the same time in every condensate, regardless of its size.

Central Charge for AdS_2 Quantum Gravity

description: Two-dimensional Maxwell-dilaton quantum gravity on AdS_2 with radius $\ell$ and a constant electric field E is studied. In conformal gauge, this is equivalent to a CFT on a strip. In order to maintain consistent boundary conditions, the usual conformal diffeomorphisms must be accompanied by a certain U(1) gauge transformation. The resulting conformal transformations are generated by a twisted stress tensor, which has a central charge $c={3k E^2 \ell^4/4}$ where k is the level of the U(1) current. This is an AdS_2 analog of the Brown-Henneaux formula $c = 3\ell/2G$ for the central charge of quantum gravity on AdS_3.

description: The resolving power of solid-state nuclear magnetic resonance (NMR) crystallography depends heavily on the accuracy of computational predictions of NMR chemical shieldings of candidate structures, which are usually taken to be local minima in the potential energy. To test the limits of this approximation, we systematically study the importance of finite-temperature and quantum nuclear fluctuations for $^1$H, $^{13}$C, and $^{15}$N shieldings in polymorphs of three paradigmatic molecular crystals -- benzene, glycine, and succinic acid. The effect of quantum fluctuations is comparable to the typical errors of shielding predictions for static nuclei with respect to experiments, and their inclusion to improve the agreement with measurements, translating to more reliable assignment of the NMR spectra to the correct candidate structure. The use of integrated machine-learning models, trained on first-principles energies and shieldings, renders rigorous sampling of nuclear fluctuations affordable, setting a new standard for the calculations underlying NMR structure determinations.

description: The present dissertation is concerned with the access and establishment of Theatre Education into the school curriculum and the training program of Greek scholars. Firstly, it processes the structural elements of the concept of theatre, as well as its context, and, then, breaks up the recommendation of the dramatic text into the elements that make it up, so that everyone can potentially understand how these elements make a dramatic text, the theatrical character of every kind of text. Thus, according to all the above data, Theatre in Education seeks to promote the idea of action and dialogue into the teaching and learning process, whereas everyone will participate equally in the theatrical and pedagogical activities.
Anomalous Andreev interferometer: Study of an anomalous Josephson junction coupled to a normal wire

description: Josephson junctions (JJs), where both time-reversal and inversion symmetry are broken, exhibit a phase shift $ϕ_0$ in their current-phase relation. This allows for an anomalous supercurrent to flow in the junction even in the absence of a phase bias between the superconductors. We show that a finite phase shift also manifests in the so-called Andreev interferometers - a device that consists of a mesoscopic conductor coupled to the $ϕ_0$-junction. Due to the proximity effect, the resistance of this conductor is phase-sensitive - it oscillates by varying the phase of the JJ. As a result, the quasiparticle current $I_{\mathrm{qp}}$ flowing through the conductor has an anomalous component, which exists only at finite $ϕ_0$. Thus, the Andreev interferometry could be used to probe the $ϕ_0$ effect. We consider two realizations of the $ϕ_0$-junction and calculate $I_{\mathrm{qp}}$ in the interferometer: a superconducting structure with spin-orbit coupling and a system of spin-split superconductors with spin-polarized tunneling barriers.

description: We describe results from a new ground-based monitoring campaign on NGC 5548, the best studied reverberation-mapped AGN. We find that it was in the lowest luminosity state yet recorded during a monitoring program, namely L(5100) = 4.7 x 10^42 ergs s^-1. We determine a rest-frame time lag between flux variations in the continuum and the Hbeta line of 6.3 (+2.6/-2.3) days. Combining our measurements with those of previous campaigns, we determine a weighted black hole mass of M_BH = 6.54 (+0.26/-0.25) x 10^7 M_sun based on all broad emission lines with suitable variability data. We confirm the previously-discovered virial relationship between the time lag of emission lines relative to the continuum and the width of the emission lines in NGC 5548, which is the expected signature of a gravity-dominated broad-line region. Using this lowest luminosity state, we extend the range of the relationship between the luminosity and the time lag in NGC 5548 and measure a slope that is consistent with alpha = 0.5, the naive expectation for the broad line region for an assumed form of r ~ L^alpha. This value is also consistent with the slope recently determined by Bentz et al. for the population of reverberation-mapped AGNs as a whole.

Remnant of a "Wet" Merger: NGC 34 and Its Young Massive Clusters, Young Stellar Disk, and Strong Gaseous Outflow

description: This paper presents new images and spectroscopy of NGC 34 (Mrk 938) obtained with the du Pont 2.5-m and Baade 6.5-m telescopes at Las Campanas, plus photometry of an HST archival V image. This Mv = -21.6 galaxy has often been classified as a Seyfert 2, yet recently published infrared spectra suggest a dominant central starburst. We find that the galaxy features a single nucleus, a main spheroid containing a blue central disk, and tidal tails indicative of two former disk galaxies. These galaxies appear to have completed merging. The remnant shows three clear optical signs that the merger was gas-rich ("wet") and accompanied by a starburst: (1) It sports a rich system of young star clusters, of which 87 have absolute magnitudes -10.0 > Mv > -15.4. Five clusters with available spectra have ages in the range 0.1-1.0 Gyr, photometric masses between 2x10^6 and 2x10^7 Msun, and are gravitationally bound young globulars. (2) The blue central disk appears to be young. It is exponential, can be traced to >10 kpc radius, and has a smooth structure and colors suggest- ing a dominant, ~400 Myr old poststarburst population. And (3), the center of NGC 34 drives a strong outflow of cool, neutral gas, as revealed by broad blueshifted Na I D lines. The mean outflow velocity of this gas is -620 km/s, while the maximum velocity reaches -1050 km/s. We suggest that NGC 34 stems from two recently merged gas-rich disk galaxies with an estimated mass ratio between 1/3 and 2/3. The remnant seems to have first experienced a galaxy-wide starburst that then shrank to its current central and obscured state. The strong gaseous outflow came last. (Abridged)

description: We propose an unconventional solution to high-performance ray tracing that combines a ray ordering scheme that minimizes access to the scene data with a large on-chip buffer acting as near-compute storage that is spread over multiple chips. We demonstrate the effectiveness of our approach by introducing Mach-RT (Many chip - Ray Tracing), a new hardware architecture for accelerating ray tracing. Extending the concept of dual streaming, we optimize the main memory accesses to a level that allows the same memory system to service multiple processor chips at the same time. While a multiple chip solution might seem to imply increased energy consumption as well, because of the reduced memory traffic we are able to demonstrate, performance increases while maintaining reasonable energy usage compared to academic and commercial architectures.

description: The aim of this master thesis was the selective catalytic reduction of nitrogen oxides by hydrocarbons over zirconia catalysts promoted by tungsten oxide and palladium. These catalysts were characterized using material characterization methods such as X-ray diffraction (XRD), BET method, transmission electron microscopy (ΤΕΜ), temperature-programmed desorption of ammonia (TPD-NH3) etc. Moreover, their performance in nitrogen oxide reduction was studied varying the tungsten oxide loading, the hydrocarbon type and the concentration of oxygen in the feed. Finally, the mechanism of the catalyst that presented the best performance was studied, conducting temperature-programmed surface reaction experiments using oxygen or hydrocarbons during the desorption.

description: Existing protocols for benchmarking current quantum co-processors fail to meet the usual standards for assessing the performance of High-Performance-Computing platforms. After a synthetic review of these protocols -- whether at the gate, circuit or application level -- we introduce a new benchmark, dubbed Atos Q-score (TM), that is application-centric, hardware-agnostic and scalable to quantum advantage processor sizes and beyond. The Q-score measures the maximum number of qubits that can be used effectively to solve the MaxCut combinatorial optimization problem with the Quantum Approximate Optimization Algorithm. We give a robust definition of the notion of effective performance by introducing an improved approximation ratio based on the scaling of random and optimal algorithms. We illustrate the behavior of Q-score using perfect and noisy simulations of quantum processors. Finally, we provide an open-source implementation of Q-score that makes it easy to compute the Q-score of any quantum hardware.

description: We explore a first proof-of-concept example of creatively using the Turing generation's hardware ray tracing cores to solve a problem other than classical ray tracing, specifically, point location in unstructured tetrahedral meshes. Starting with a CUDA reference method, we describe and evaluate three different approaches to reformulate this problem in a manner that allows it to be mapped to these new hardware units. Each variant replaces the simpler problem of point queries with the more complex one of ray queries; however, thanks to hardware acceleration, these approaches are actually faster than the reference method.

description: The increased capabilities of coupling more and more materials through functional interfaces are paving the way to a series of exciting experiments and extremely advanced devices. Here we focus on the capability of magnetically inhomogeneous superconductor/ferromagnet (S/F) interfaces to generate spin-polarized triplet pairs. We build on previous achievements on spin-filter ferromagnetic Josephson junctions (JJs) and find unique correspondence between neat experimental benchmarks in the temperature behavior of the critical current and theoretical modeling based on microscopic calculations, which allow us to determine a posteriori spin-singlet and triplet correlation functions. This kind of combined analysis provides accurate proof of the coexistence and tunability of singlet and triplet transport. This turns to be a unique opportunity to model disorder and spin-mixing effects in a JJ to enlarge the space of parameters, which regulate the phenomenology of the Josephson effect and could be applied to a variety of novel types of JJs.

description: Στόχος της διπλωματικής εργασίας ήταν η ανάπτυξη συστημάτων διαχείρισης αποθεμάτων για επιλεγμένα προϊόντα μιας εμπορικής επιχείρησης και, συγκεκριμένα ενός καταστήματος Starbucks (γνωστή αλυσίδα καφέ). Το ιδιαίτερο χαρακτηριστικό της ζήτησης για τα SKUs (Stock keeping units) που μελετώνται είναι το γεγονός ότι η ζήτηση είναι στοχαστική και μάλιστα σε όλους τους κωδικούς παρουσιάζει εποχικότητα. Έγινε προσπάθεια παραμετροποίησης ενός συστήματος διαχείρισης αποθέματος με στοχαστική ζήτηση για σταθερή περίοδο αναθεώρησης του αποθέματος λαμβάνοντας υπόψη τις επιδράσεις των διαφορετικών εποχών στη διάρκεια ενός έτους. Συγκεκριμένα μελετήθηκαν επιλεγμένοι κωδικοί αποθεμάτων, η επιλογή των οποίων βασίστηκε σε μια ABC ανάλυση. Στη συνέχεια της προσπάθειας παραμετροποίησης του συστήματος διαχείρισης των επιλεγμένων κωδικών, μελετήθηκαν οι οικογένειες προϊόντων από τις οποίες προέρχονται οι συγκεκριμένοι κωδικοί και σχεδιάστηκαν μοντέλα πρόβλεψης της ζήτησης αυτών. Έπειτα δεδομένου της έλλειψης στοιχείων κόστους προβήκαμε στη μελέτη και υιοθέτηση συστήματος διαχείρισης αποθεμάτων σταθερής περιόδου παραγγελίας (R,S). Τέλος, σχεδιάσαμε και τρέξαμε ένα μοντέλο προσομοίωσης για ένα κωδικό, ώστε να αξιολογήσουμε τα αποτελέσματα που προκύπτουν για συγκεκριμένες παραμέτρους, όπως το μέσο ετήσιο διατηρούμενο απόθεμα, η μέση ετήσια έλλειψη κ.α., από το προτεινόμενο σύστημα διαχείρισης και προχωρήσαμε σε σύγκριση τεσσάρων επιμέρους σεναρίων ανανέωσης αποθέματος.
description: The aim of the present thesis was the development of inventory management systems for selected products of a commercial enterprise, in particular a Starbucks store (global coffee company). The special feature of demand for the studied SKUs (Stock keeping units) is the fact that is probabilistic and especially the time series of the demand exhibit cyclic variation known as seasonal variation or seasonality. We attempted a configuration in the inventory management system with probabilistic demand for a periodic review model of stock, with constant period, taking into account the effects of different seasons in a year. Specifically, selected SKUs are studied, whose selection was based on an ABC analysis. Then in order to continue the configuration effort, we studied the families of products from which the specific SKUs come, and we designed models for forecasting the demand of them. Then because of the lack of inventory cost data we proceeded to the study and adoption stock fixed period review management system (R, S). Finally, we design and run a simulation model for a SKU to evaluate the results in certain parameters, such as the average annual keeping inventory, the average annual shortage and others, of the proposed inventory management system and we compare four different scenarios four scenarios for the inventory replenishment.

Εξίσου σημαντικά στοιχεία της μελέτης είναι η προσπάθεια επεξήγησης της διαφοροποίησης του δεδικασμένου από τις παρεμφερείς έννοιες της διαπλαστικής ενέργειας και της υποχρέωσης συμμόρφωσης, οι οποίες στο πεδίο των συνεπειών των διοικητικών αποφάσεων δημιουργούν τους μεγαλύτερους κινδύνους σύγχυσης με το θεσμό του δεδικασμένου. Τέλος, η μελέτη προχωρά και σε μια σύντομη αναφορά στις κοινοτικές και ευρωπαϊκού δικαίου προεκτάσεις του δεδικασμένου, με ειδικότερες αναφορές στη διοικητική δίκη, ενόψει της δέσμευσης του εθνικού δικαστή από τους κοινοτικούς κανόνες αυξημένης τυπικής ισχύος και την ΕΣΔΑ, όπως επίσης και από τις νομολογιακές επιταγές των ευρωπαϊκών δικαστηρίων.
description: The subject of the present thesis is the enquiry of the precedent institution in both cancellation and substantial trial, having the demarcation of the “administrative nature issue” as a main component, which is a -hard to explain- cause of the determination of the extend of precedent and prompt for exuberant theoretical and case-law research and conflict. In the field of the main aspects of the final effect of the administrative courts’ judgments, the explanation of the differentiation of the precedent from the similar factotum of formation act and compulsory compliance, which generate likelihood of confusion compared to the meaning of the precedent, is equally important. Finally, the study moves to a brief reference to the european and european union law extensions of the precedent, regarding the administrative trial, in view of the national judge’s commitment to the increased strength union rules and to the European Convention of Human Rights (ECHR), as well as the case law dictations of the union courts.
Wide BVH Traversal with a Short Stack

description: Compressed wide bounding volume hierarchies can significantly improve the performance of incoherent ray traversal, through a smaller working set of inner nodes and therefore a higher cache hit rate. While inner nodes in the hierarchy can be compressed, the size of the working set for a full traversal stack remains a significant overhead. In this paper we introduce an algorithm for wide bounding volume hierarchy (BVH) traversal that uses a short stack of just a few entries. This stack can be fully stored in scarce on-chip memory, which is especially important for GPUs and dedicated ray tracing hardware implementations. Our approach in particular generalizes the restart trail algorithm for binary BVHs to BVHs of arbitrary widths. Applying our algorithm to wide BVHs, we demonstrate that the number of traversal steps with just five stack entries is close to that of a full traversal stack. We also propose an extension to efficiently cull leaf nodes when a closer intersection has been found, which reduces ray primitive intersections by up to 14%.

description: Two of the most rapidly growing observables in cosmology and astrophysics are gravitational waves (GW) and the neutral hydrogen (HI) distribution. In this work, we investigate the cross-correlation between resolved gravitational wave detections and HI signal from intensity mapping (IM) experiments. By using a tomographic approach with angular power spectra, including all projection effects, we explore possible applications of the combination of the Einstein Telescope and the SKAO intensity mapping surveys. We focus on three main topics: \textit{(i)} statistical inference of the observed redshift distribution of GWs; \textit{(ii)} constraints on dynamical dark energy models as an example of cosmological studies; \textit{(iii)} determination of the nature of the progenitors of merging binary black holes, distinguishing between primordial and astrophysical origin. Our results show that: \textit{(i)} the GW redshift distribution can be calibrated with good accuracy at low redshifts, without any assumptions on cosmology or astrophysics, potentially providing a way to probe astrophysical and cosmological models; \textit{(ii)} the constrains on the dynamical dark energy parameters are competitive with IM-only experiments, in a complementary way and potentially with less systematics; \textit{(iii)} it will be possible to detect a relatively small abundance of primordial black holes within the gravitational waves from resolved mergers. Our results extend towards $\mathrm{GW \times IM}$ the promising field of multi-tracing cosmology and astrophysics, which has the major advantage of allowing scientific investigations in ways that would not be possible by looking at single observables separately.

Inverting Phase Functions to Map Exoplanets

Subjects: subject: Astrophysics (astro-ph)

description: We describe how to generate a longitudinal brightness map for a tidally locked exoplanet from its phase function light curve. We operate under a number of simplifying assumptions, neglecting limb darkening/brightening, star spots, detector ramps, as well as time-variability over a single planetary rotation. We develop the transformation from a planetary brightness map to a phase function light curve and simplify the expression for the case of an edge-on system. We introduce two models--composed of longitudinal slices of uniform brightness, and sinusoidally varying maps, respectively--which greatly simplify the transformation from map to light curve. We discuss numerical approaches to extracting a longitudinal map from a phase function light curve, explaining how to estimate the uncertainty in a computed map and how to choose an appropriate number of fit parameters. We demonstrate these techniques on a simulated map and discuss the uses and limitations of longitudinal maps. The sinusoidal model provides a better fit to the planet's underlying brightness map, although the slice model is more appropriate for light curves which only span a fraction of the planet's orbit. Regardless of which model is used, we find that there is a maximum of ~5 free parameters which can be meaningfully fit based on a full phase function light curve, due to the insensitivity of the latter to certain modes of the map.

A tormented soul in a locked hut: Can Xue’s short stories
Creators: name: Li, Tianming
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is about Can Xue’s short stories. Can Xue, the pen name of Deng Xiaohua, is a contemporary Chinese woman writer. Her work is characterized by innovation and she is considered by some critics one of the most non-traditional and modernistic Chinese writer. The Introduction of the thesis introduces diverse evaluations of Can Xue’s works and gives the purpose of the thesis, that is, to review Can Xue’s significant short stories and to make my own aesthetic evaluation of them. The thesis divides Can Xue’s short stories into two basic categories: the allegorical and the symbolic. A number of their themes are identified and different features of both the allegorical and the symbolic stories are illustrated. Following this, the focus of the thesis shifts to the artistic techniques of Can Xue’s short stories. The modes of allegory and symbolism, the surrealistic imagination and illogical narrative, and the device of anti typification are examined in detail. Finally, particular attention is paid to making an aesthetic appraisal of Can Xue’s short stories.

Soils with Spodic Characteristics on the Eastern Shore of Maryland
Creators: name: Condron, Margaret Anne
Publisher: name: Digital Repository at the University of Maryland
Year: 1990

description: A seasonally fluctuating water table may be an important
factor in the formation of spodic horizons in sandy,
quartzose sediments on the Lower Eastern Shore of
Maryland. This study was conducted to examine spodic
horizon formation and expression along two topohydrosequences.
After a reconnaissance study, two
research sites were chosen in the Pocomoke State Forest in
Worcester County, Maryland.
The soils were classified according to Soil Taxonomy as
siliceous, mesic, Typic Quartzipsamments, Aquic
Haplorthods, and Aerie and Typic Haplaquods. The spodic
horizons were thickest (26-204cm) in the wettest
positions. Total organic carbon, pyrophosphateextractable
carbon, and extractable aluminum were greatest
in the spodic horizons, and there was little extractable
iron in the Haplaquods. There was less structural
aluminum and potassium in the surface horizons than in the
lower horizons. This suggests that feldspar weathering in
the surface horizons provides a source of aluminum for the
spodic horizon formation. Quantitative estimates of
pedogenesis showed net gains of extractable aluminum,
total (organic) carbon, and pyrophosphate carbon in the
lower landscape positions. The seasonally fluctuating
water table appears to influence the movement of soluble
organic aluminum complexes through the soil downslope, as
well as within the pedon from the surface to subjacent
horizons.
