description: The Virgo Cluster is the dominant mass concentration in the Local Supercluster and the largest collection of elliptical and lenticular galaxies in the nearby universe. In this paper, we present an introduction to the ACS Virgo Cluster Survey: a program to image, in the F475W and F850LP bandpasses (Sloan g and z), 100 early-type galaxies in the Virgo Cluster using the Advanced Camera for Surveys on the Hubble Space Telescope. We describe the selection of the program galaxies and their ensemble properties, the choice of filters, the field placement and orientation, the limiting magnitudes of the survey, coordinated parallel observations of 100 "intergalactic" fields with WFPC2, and supporting ground-based spectroscopic observations of the program galaxies. In terms of depth, spatial resolution, sample size and homogeneity, this represents the most comprehensive imaging survey to date of early-type galaxies in a cluster environment. We briefly describe the main scientific goals of the survey which include the measurement of luminosities, metallicities, ages, and structural parameters for the many thousands of globular clusters associated with these galaxies, a high-resolution isophotal analysis of galaxies spanning a factor of ~ 450 in luminosity and sharing a common environment, the measurement of accurate distances for the full sample of galaxies using the method of surface brightness fluctuations, and a determination of the three-dimensional structure of Virgo itself.

description: For almost all the structures, concrete has been used as a basic and important construction material. It is made up of
the mixture of cement, coarse aggregate, fine aggregate and water. Its properties depend upon W/C ratio, humidity,
size of aggregate, type of components used, admixture used, amount of component used. While making a concrete
structure, it is very essential to prepare it to eliminate its major drawbacks such as poor workability, surplus
admixtures, honey combing of members, improper mixing. It should be kept in mind that these factors will affect the
entire structure and leads to the destruction. To access the condition of the structure, UPV tests are very popular Non
Destructive Test of concrete. This study deals with the UPV test procedure approach in Dry and Wet condition of
concrete specimen with the use of probe location on various fragments. The results of both pre and post curing of the
RCC block have been discussed in this paper with the recommendation of use of probe location. This study is
entirely concentrated on pre and post curing to know the hydration behavior of concrete after placing.

description: In physics and materials science, plasticity, also known as plastic deformation, is the ability of a solid material to undergo permanent deformation, a non-reversible change of shape in response to applied forces. For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur within the material itself. In engineering, the transition from elastic behavior to plastic behavior is known as yielding.

Wave turbulence and Bose-Einstein condensates

Year: 2004
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: Asymptotic behavior of a class of nonlinear Schrödinger equations are studied. Particular cases of 1D weakly focusing and Bose-Einstein condensates are considered. A statistical approach is presented to describe the stationary probability density of a discretized finite system. Using a maximum entropy argument, the theory predicts that the statistical equilibrium is described by energy equivalued fluctuation modes around the coherent structure minimizing the Hamiltonian of the system. Good quantitative agreement is found with numerical simulations. In particular, the particle number spectral density follows an effective $1/k^2$ law for the asymptotic large time averaged solutions. Transient dynamics from a given initial condition to the statistically steady regime shows rapid oscillation of the condensate.

description: Inspired by a recent experiment by Steinhauer and co-workers, we present a simple model which describes the formation of an acoustic black hole in a Bose-Einstein condensate, allowing an analytical computation of the evolution in time of the corresponding density-density correlator. We show the emergence of analog Hawking radiation out of a "quantum atmosphere" region significantly displaced from the horizon. This is quantitatively studied both at $T=0$ and even in the presence of an initial temperature T, as is always the case experimentally.

Wildwood notes : nature writing, music, and newspapers
Creators: name: Szabo, Lisa Sara
Publisher: name: University of British Columbia

description: During the first half of the twentieth century, British Columbia was comprised of small clusters of settlements connected by tracts of forests, rivers, coastal waters, rural farmland, rail lines, and few paved roads. While municipal newspapers formed local identities, provincial daily newspapers interconnected British Columbia's disparate towns and villages into wider regional affiliation. By examining the genre of the nature writing, particularly naturalist accounts disseminated through the newsprint, I propose that as the daily newspaper's medium brings the everyday into peoples' homes, the serial nature essay conveys a "unique syntax" of bioregional commonplace into the reader's day-to-day living. Newspapers bring the outside world into the intimate sphere of the home on a regular basis; A serial nature essay, especially one that focuses on the local, delivered in the medium of newsprint extends this outside world to include events occurring in nature. Further, I express how musical troping, a key characteristic of nature writing, teaches readers how to listen to and to detect the well-being/distress of a bioregional community, and thus cultivate an ethic of care for the natural environment; naturalist writing, thus acts as an antiphony to the deafening cacophony of environmental crisis news. My thesis examines, in particular, B.C. naturalist John William Winson's serial nature columns "Open Air Jottings" and "Along Wildwood Trails," which appeared in the Vancouver Daily Province from 1918 to 1956. John Winson's writings, written under the pseudonym 'Wildwood', invite the communities of British Columbia to envision membership in a wider Pacific Northwest bioregional community—a relationship that sees beyond and dissolves the divisions of political and geographic borders, species, and human culture. By recuperating and re-reading Wildwood's "forgotten naturalist" column, specifically disseminated through newsprint, I analyze how his writings both promote and complicate the formation of a Pacific Northwest regional identity; specifically, the tensions between the genre's imperialistic frameworks (First Nations representation and literary ecological imperialism), which domesticate new lands for immigrants and the transformative experiences resulting from encounters with new environments and cultures, experiences that require new ways of seeing and interacting.

description: Data-driven problem solving in many real-world applications involves analysis of time-dependent multivariate data, for which dimensionality reduction (DR) methods are often used to uncover the intrinsic structure and features of the data. However, DR is usually applied to a subset of data that is either single-time-point multivariate or univariate time-series, resulting in the need to manually examine and correlate the DR results out of different data subsets. When the number of dimensions is large either in terms of the number of time points or attributes, this manual task becomes too tedious and infeasible. In this paper, we present MulTiDR, a new DR framework that enables processing of time-dependent multivariate data as a whole to provide a comprehensive overview of the data. With the framework, we employ DR in two steps. When treating the instances, time points, and attributes of the data as a 3D array, the first DR step reduces the three axes of the array to two, and the second DR step visualizes the data in a lower-dimensional space. In addition, by coupling with a contrastive learning method and interactive visualizations, our framework enhances analysts' ability to interpret DR results. We demonstrate the effectiveness of our framework with four case studies using real-world datasets.

description: Quantum key distribution (QKD) is one of the most practical applications in quantum information processing, which can generate information-theoretical secure keys between remote parties. With the help of the wavelength-division multiplexing technique, QKD has been integrated with the classical optical communication networks. The wavelength-division multiplexing can be further improved by the mode-wavelength dual multiplexing technique with few-mode fiber (FMF), which has additional modal isolation and large effective core area of mode, and particularly is practical in fabrication and splicing technology compared with the multi-core fiber. Here, we present for the first time a QKD implementation coexisting with classical optical communication over weakly-coupled FMF using all-fiber mode-selective couplers. The co-propagation of QKD with one 100 Gbps classical data channel at -2.60 dBm launched power is achieved over 86 km FMF with 1.3 kbps real-time secure key generation. Compared with single-mode fiber, the average Raman noise in FMF is reduced by 86% at the same fiber-input power. Our work implements an important approach to the integration between QKD and classical optical communication and previews the compatibility of quantum communications with the next-generation mode division multiplexing networks
Zum Problem der saaleeiszeitlichen Terrassenbildungen im Unterlauf der Werre

description: Die problematische Stellung der saaleeiszeitlichen Terrassenablagerungen der Werre, die sich aus der einschlägigen Literatur und den Geologischen Karten ergibt, veranlaßte den Verf. zu Terrassenuntersuchungen am Unterlauf der Werre bei Gohfeld und Bad Oeynhausen. Vor allem wurden der stratigraphische Aufbau der Ablagerungen untersucht und Rundungsmessungen an Quarzkörnern vorgenommen. Als Beispiel wird die Terrasse bei Gohfeld, Nähe Bahnhof, an der eiszeitlichen Einmündung des Sudbaches in die Werre näher beschrieben und klimatisch gedeutet. Im Hangenden des Terrassenkörpers befinden sich solifluidaler Wanderschutt bzw. Niederterrassenablagerungen, im Liegenden saaleeiszeitliche Sande und Kiese mit tieferreichenden Froststrukturen. Bei den Kiesen handelt es sich um nordische Feuersteine; die Porphyre und Granite stammen aus dem Thüringer Wald und sind daher ursprünglich von der Weser herantransportiertes, mehrfach umgelagertes Material. Die überwiegende Mehrzahl der Quarzkörner ist mittelmäßig gerundet und auf jeden Fall transportbeansprucht. Für eine einheitliche Fließgeschwindigkeit des Flusses und Akkumulation im Mittelterrassenkörper spricht die relativ gute Sortierung, denn Anzeichen für Staubeckenbildungen wurden bisher nicht gefunden. Zu Beginn der Saaleeiszeit lag die Talsohle der Werre bei Gohfeld im Lias etwas über dem Niveau der heutigen Talaue. Die Anknüpfungen der Terrassen des Werreunterlaufs an die saaleeiszeitlichen Flußablagerungen im Wesersystem konnten festgestellt werden.

description: Analytic approximations for synchrotron, synchrotron self-Compton (SSC), and external Compton (EC) processes are used to constrain model parameters for knot and hot-spot emission in extended jets of radio galaxies. Equipartition formulas are derived that relate the Doppler factor $δ$ and comoving magnetic field $B$ assuming a nonthermal synchrotron origin of the radio emission, and synchrotron, SSC and EC origins of the X-ray emission. Expressions are also derived for $δ$ and $B$ that minimize the total jet powers of the emitting region in synchrotron, SSC and EC models for the X-ray emission. The results are applied to knot WK7.8 of PKS 0637-752. Predictions to test two-component synchrotron and EC models are made for {\it Chandra} and {\it GLAST}.

Verlandete Altwässer auf der Niederterrasse bei Köln?: Die Entstehung des Linder Bruchs aufgrund einer Pollen- und Großrestanalyse
Creators: name: Peters, Ilse
Publisher: name: Geozon Science Media
Year: 1966

description: Das auf der rechten Niederterrasse des Rheins südlich Wahn gelegene Linder Bruch wurde pollenanalytisch untersucht und als Ergänzung eine Analyse der Makroflora durchgeführt. Die Ergebnisse zeigen, daß die organischen Ablagerungen erst an der Pollengrenze X/XI (nach Overbeck & Schneider) beginnen, und daß sie nicht aus einem Altwasser hervorgegangen sind. Das Linder Bruch entstand vielmehr durch die sekundäre Versumpfung einer ausgetrockneten Flußrinne, die wahrscheinlich dem Rheinsystem angehört. Die zur Versumpfung notwendigen Wassermassen lieferte die unmittelbar benachbarte Mittelterrasse. Ungeklärt bleibt zunächst noch die Frage nach der unterschiedlichen Wasserzufuhr in das Linder Bruch. Hier könnten Beziehungen zu einer wechselnden Bewaldung in Verbindung mit der Besiedlung der Mittelterrasse bestehen. Auch die Ursachen der Verhinderung einer früheren Versumpfung bedürfen noch der Feststellung. Es wird die Vermutung ausgesprochen, daß das Merheimer Bruch bei Köln, das ähnlich wie das Linder Bruch in einer ehemaligen Flußrinne auf der rechten Niederterrasse des Rheins liegt, ebenfalls durch eine sekundäre Versumpfung entstanden ist.

A long look at the BALQSO LBQS 2212-1759 with XMM-Newton

description: Very long (172 ks effective exposure time) observations of the BALQSO LBQS 2212-1759 with XMM-Newton yield a stringent upper-limit on its 0.2-10 keV (rest- frame 0.64-32.2 keV) flux, F < 6 E-17 erg/cm2/s, while simultaneous UV and optical observations reveal a rather blue spectrum extending to 650 A in the source rest frame. These results are used to set a tight upper-limit on its optical to X-ray spectral index alpha_{ox} < -2.56. Given the HI-BAL nature of LBQS 212-1759, its X-ray weakness is most likely due to intrinsic absorption. If this is the case, and assuming that the intrinsic alpha_{ox} of LBQS 2212-1759 is -1.63 - a value appropriate for a radio-quiet quasar of this luminosity - one can set a lower limit on the X-ray absorbing column N_{H} > 3.4 E25 cm-2. Such a large column has a Thomson optical depth to electron scattering tau > 23, sufficient to extinguish the optical and UV emission. The problem only gets worse if the gas is neutral since the opacity in the Lyman continuum becomes extremely large, > 2 E8, conflicting with the source detection below 912 A. This apparent contradiction probably means that our lines-of-sight to the X-ray and to the UV emitting regions are different, such that the gas covers completely the compact X-ray source but only partially the more extended source of ultraviolet photons. An extended (~ 1') X-ray source is detected 2' to the south-east of the QSO. Given its thermal spectrum and temperature (1.5 < T < 3.0 keV}, it is probably a foreground (0.29 < z < 0.46) cluster of galaxies.

Roles of Confined Placental Mosaicism (CPM) and H19/IGF2 imprinting in pregnancies derived from intracytoplasmic sperm injection (ICSI)
Creators: name: Hatakeyama, Chiho
Publisher: name: University of British Columbia
Year: 2011

description: In contrast to the success of ICSI in treating male infertility, concerns have been raised about the health outcomes of the children conceived through this procedure. Cohort studies have shown that the ICSI population has an increase in low birth weight (LBW), birth defects, chromosomal abnormalities, and imprinting disorders. However, the underlying causes remain unknown. Two potential risk factors for these negative pregnancy outcomes, particularly for LBW, were investigated in this study - Confined Placental Mosaicism (CPM) and epigenetic defects at the differentially methylated region (DMR) of H19/IGF2. CPM was examined in villi from thirty post-delivery placentas derived from ICSI after confirming a normal karyotype in cord blood. Subsequently, the parental origin was determined in detected CPM as well as in non-mosaic chromosomal abnormalities ascertained through spontaneous abortions. When a paternal origin was confirmed, aneuploidy in sperm from the father was investigated. Finally, methylation pattern at two CpG sites from the DMR of H19/IGF2 was quantitatively analyzed in placentas from ICSI pregnancies with LBW (n=10) and with normal BW (n=12). Placentas from natural conceptions (n=14) served as controls. Among the thirty placentas, one monosomy X case was detected from a conceptus with a normal blood karyotype and pregnancy outcomes. Thus, the incidence of CPM was 3.3% in the study population, which is not significantly different from the rate observed in the general population (6.0%). A paternal origin was revealed in one out of four cases, which include chromosome abnormalities derived from CPM (n=2) and spontaneous abortions (n=2). In the paternally inherited t(13;21) case, 88.39% of the sperm were normal or balanced, and 7.29% were nullisomic or disomic for chromosome 13 and 21. In methylation analysis, differences were not found among the three groups; however, hypomethylation (<33%) was exclusively detected from the ICSI-LBW group. Taken together, the roles of CPM and epigenetic alteration at the DMR of H19/IGF2 were not apparent in ICSI pregnancies studied, regardless of the pregnancy outcomes. However, due to the limited sample size, we cannot exclude the possibility that these factors may play a role in certain cases that were not included in the present study.
On the internal structure of starless cores. I. Physical conditions and the distribution of CO, CS, N2H+, and NH3 in L1498 and L1517B

description: We have characterized the physical structure and chemical composition of two close-to-round starless cores in Taurus-Auriga, L1498 and L1517B. Our analysis is based on high angular resolution observations in at least two transitions of NH3, N2H+, CS, C34S, C18O, and C17O, together with maps of the 1.2 mm continuum. For both cores, we derive radial profiles of constant temperature and constant turbulence, together with density distributions close to those of non-singular isothermal spheres. Using these physical conditions and a Monte Carlo radiative transfer model, we derive abundance profiles for all species and model the strong chemical differentiation of the core interiors. According to our models, the NH3 abundance increases toward the core centers by a factor of several while N2H+ has a constant abundance over most of the cores. In contrast, both C18O and CS (and isotopomers) are strongly depleted in the core interiors, most likely due to their freeze out onto grains at densities of a few 10^4 cm^{-3}. Concerning the kinematics of the dense gas, we find (in addition to constant turbulence) a pattern of internal motions at the level of 0.1 km s^{-1}. These motions seem correlated with asymmetries in the pattern of molecular depletion, and we interpret them as residuals of core contraction. Their distribution and size suggest that core formation occurs in a rather irregular manner and with a time scale of a Myr. A comparison of our derived core properties with those predicted by supersonic turbulence models of core formation shows that our Taurus cores are much more quiescent than representative predictions from these models.

description: Nach Vorarbeiten 1977 und 1979 wurden im Bereich der paläolithischen Fundstelle Şehremuz im Jahre 1982 zwei Grabungskampagnen von je zwei Monaten durchgeführt. Es konnten zwei archäologische Komplexe in unterschiedlicher geologischer Lagerung festgestellt werden: a) Silexabschläge und Faustkeile im obersten aufgeschlossenen Schotter des Keluşk-Baches, eines Euphratzuflusses. Dieser Seitentalschotter ist korrelierbar mit einem etwa 60 m über der heutigen Talaue liegenden Euphratschotter. b) „Mittelpaläolithische" Inventare in einem über den Keluşk-Schottern liegenen Glacis, weitgehend nur aus Oberflächenfunden bekannt. Sie sind aufgrund ihrer Einlagerung jünger als der "Faustkeilkomplex". Die Inventare mit Faustkeilen sind einem entwickelten faustkeilführenden Paläolithikum zuzurechnen. Auf sie ist die vorliegende Untersuchung konzentriert. Die durch die Silexartefakte belegten zahlreichen Begehungen des alten Keluşk-Bettes durch den paläolithischen Menschen haben ihre Ursache u.a. in einem hohen natürlichen Anteil von Silex im Schotter. Neben vollständigen Knollen liegt zahlreicher Naturbruch vor, der gegen die Stücke mit anthropogenen Bearbeitungsspuren abgegrenzt werden muß. Dabei kommt der Konfiguration der Einzelmerkmale — Dimensionen; Abbaufläche und Schlagmerkmale — die größte Bedeutung zu. Die Bearbeitung der Steinartefakte unter funktionalen Gesichtspunkten ist ein wichtiger Teil der Untersuchungen: Die Methoden werden beschrieben. Form und Zurichtung der Faustkeile lassen makroskopisch mögliche Funktionsflächen zum tiefen Einschneiden etwa in Fleisch und mögliche Funktionskanten zum Ritzen oder flach Einschneiden erkennen. Im mikroskopischen Bereich werden an Artefakten punktuell Gebrauchsspuren faßbar, die z.B. die Benutzung eines Faustkeils sowohl zum Einschneiden in Fleisch wie auch zum Zertrümmern von Knochen belegen.

description: The objective of this study is to understand the dynamics of freely evolving particle suspensions over a wide range of particle-to-fluid density ratios. The dynamics of particle suspensions are characterized by the average momentum equation, where the dominant contribution to the average momentum transfer between particles and fluid is the average drag force. In this study, the average drag force is quantified using particle-resolved direct numerical simulation in a canonical problem: a statistically homogeneous suspension where an imposed mean pressure gradient establishes a steady mean slip velocity between the phases. The effects of particle velocity fluctuations, particle clustering, and mobility of particles are studied separately. It is shown that the competing effects of these factors could decrease, increase, or keep constant the drag of freely evolving suspensions in comparison to fixed beds at different flow conditions. It is also shown that the effects of particle clustering and particle velocity fluctuations are not independent. Finally, a correlation for interphase drag force in terms of volume fraction, Reynolds number, and density ratio is proposed. Two different approaches (symbolic regression and predefined functional forms) are used to develop the drag correlation. Since this drag correlation has been inferred from simulations of particle suspensions, it includes the effect of the motion of the particles. This drag correlation can be used in computational fluid dynamics simulations of particle-laden flows that solve the average two-fluid equations where the accuracy of the drag law affects the prediction of overall flow behavior.

description: Die Untersuchung fossiler Böden in einigen Landschaften des eisfreien Gebietes hat ergeben, daß die verschiedenen Verwitterungszeiten des jüngeren Pleistozäns durch bestimmte Bodentypen charakterisiert sind. So bildeten sich während des Riß-Würm-Interglazials im engeren Rhein-Maingebiet, in Mitteldeutschland, in Nordböhmen und Mähren Schwarzerden, die in folgende Bodenformen unterteilt werden können: 1. Kalkhaltige Schwarzerden mit normalen A/C-Profilen. 2. Degradierte Schwarzerden mit A/B/C-Profilen. 3. Podsolierte Schwarzerden mit A1/A2/B/C-Profilen. Die regionale Verteilung dieser Typen und die daraus abzuleitenden allgemeinen Klimaverhältnisse werden erläutert. Während der Würm-Interstadialzeiten entstanden folgende Bodentypen: 1. Kalkhaltige, wenig und flach verlehmte Böden; unentwickelte Böden. 2. Schwach kalkhaltige, stärker und tiefer verlehmte Böden (bis 0,8 m); nicht voll entwickelte Braunerden. 3. Kalkfreie, über 1 m tief verlehmte Böden; Braunerden. 4. Podsolierte und 5. Gleiartige Böden. In der Verbreitung dieser Bodentypen lassen sich bestimmte Unterschiede feststellen, die ebenfalls auf die Einwirkungen des Klimas zurückgeführt werden. Die Untersuchungen haben gezeigt, daß es möglich ist, mit Hilfe der Bodentypen-Sukzessionen den Klimaverlauf der betreffenden Gebiete während des jüngeren Pleistozäns in seinen Grundzügen zu erfassen. Hiermit erlangen die fossilen Böden für die gesamte Eiszeitforschung und die Paläoklimatologie eine erhöhte Bedeutung, weshalb sie besondere Aufmerksamkeit verdienen. Um jedoch Bodenkarten der einzelnen Verwitterungszeiten entwerfen zu können, die die beste Grundlage für eine regionale klimatische Auswertung darstellen, sind noch weitere Beobachtungen in den behandelten und in den übrigen Gebieten notwendig, wozu diese Arbeit einige Anregungen geben möchte.

The Fermi edge singularity in the SU(N) Wolff model
Creators: name: Dóra, Balázs
Publisher: name: arXiv
Year: 2005
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: The low temperature properties of the SU(N) Wolff impurity model are studied via Abelian bosonization. The path integral treatment of the problem allows for an exact evaluation of low temperature properties of the model. The single particle Green's function enhances due to the presence of local correlation. The basic correlation function such as the charge or spin correlator are also influenced by the presence of impurity, and show local Fermi liquid behaviour. The X-ray absorption is affected by the presence of local Hubbard interaction. The exponent is decreased (increased) for repulsive (attractive) interactions.

description: Aus dem Rheingletschergebiet werden interglaziale Verwitterungshorizonte und eine überschliffene Nagelfluh beschrieben. Der bodenkundlich genauer untersuchte Horizont von Neufra bei Riedlingen (Donau) läßt Rückschlüsse auf seine Bildungszeit zu. Infolgedessen bekommt er allgemeine stratigraphische Bedeutung für den Rheingletscher: er trennt die bisher unter „Riß" zusammengefaßte Altmoräne in Riß und Mindel. Dadurch verschieben sich alle älteren pleistozänen Schichtglieder um eine Stufe rückwärts.

description: In einer Talweitung des unteren Werratales wurden in den Terrassen-Ablagerungen fossile Böden gefunden, die im Zusammenhang mit Sedimentationsfolgen und frostdynamischen Lagerungsstörungen eine Folge von Klima- und Formungsphasen erkennen lassen. Daraus ergibt sich eine von der bisherigen abweichende Datierung und Einordnung der Sedimente. Die Lage der z. T. gut erhaltenen älteren, überlagerten Terrassen-Oberflächen läßt tektonische Bewegungen des Talbereiches im mittleren Pleistozän vermuten.

description: We prove Wigner-Eckart theorem for the irreducible tensor operators for arbitrary Hopf algebras, provided that tensor product of their irreducible representation is completely reducible. The proof is based on the properties of the irreducible representations of Hopf algebras, in particular on Schur lemma. Two classes of tensor operators for the Hopf algebra U$_{t}$(su(2)) are considered. The reduced matrix elements for the class of irreducible tensor operators are calculated. A construction of some elements of the center of U$_{t}$(su(2)) is given.

description: Two greenhouse experiments were carried out to evaluate the effect of lime on soil pH, Mn level and Al saturation and growth, dry matter production and foliar nutrient content in 6-month old cacao (Theobroma cacao L.) plants. A factorial randomized complete block design (4 genotypes x 5 treatments) was replicated 5 times. Two Ultisols from the humid zone of Puerto Rico were used. A Dystropeptic Tropudult (Maricao) with a pH of 4.8, high in Al, received four levels of lime (0, 4, 8 and 12 meq/lOOg of Ca as Ca(OH)2), and one treatment of 4 meq/lOOg Al as A12(S04)3. A Plinthic Palehumult (Torres) with a pH of 4.9 high in Mn, received four lime levels (0, 3, 6, and 9 meq/100 Ca) plus a treatment of 170 mg/kg Mn as MnSO*. Liming reduced extractable Al, Mn, P and Mg in both soils. Growth of 6-month old seedlings increased as Al and Mn decreased. Foliar P, Ca and Mg increased with liming and Al, Mn and Zn decreased. The leaves of the Al-toxic plants were small and chlorotic. In treatments where toxicity of Mn was observed, leaves had 4000 to 6000 mg/kg Mn. Young leaf interveinal areas were chlorotic and older leaves, stems and apical meristems had necrotic spots.

On the weak Leopoldt conjecture and coranks of Selmer groups of supersingular abelian varieties in $p$-adic Lie extensions
Creators: name: Lim, Meng Fai
Publisher: name: arXiv

Subjects: subject: Number Theory (math.NT)

description: Let $A$ be an abelian variety defined over a number field $F$ with supersingular reduction at all primes of $F$ above $p$. We establish an equivalence between the weak Leopoldt conjecture and the expected value of the corank of the classical Selmer group of $A$ over a $p$-adic Lie extension (not neccesasily containing the cyclotomic $\Zp$-extension). As an application, we obtain the exactness of the defining sequence of the Selmer group. In the event that the $p$-adic Lie extension is one-dimensional, we show that the dual Selmer group has no nontrivial finite submodules. Finally, we show that the aforementioned conclusions carry over to the Selmer group of a non-ordinary cuspidal modular form.
Quartale Vergletscherungen im Hindukusch, Karakorum und West-Himalaya, Pakistan - Ein Überblick

description: Für die pakistanischen Hochgebirge Hindukusch (Chitral, Swat, Ghizar-Gebiet), Karakorum (Hunza, Gilgit-Raum, Rakaposhi, Haramosh, Baltistan, K2-Region) und West-Himalaya (Nanga Parbat, Kaghan-Gebiet, Deosai-Plateau) haben glaziologische und glazialmorphologische Forschungen eine lange Tradition. Mit dem vorliegenden Beitrag wird eine Gesamtschau über den bisherigen Erkenntnisstand zu den quartären Vergletscherungen geliefert. Dabei zeigt sich, dass die Ergebnisse über die Ausdehnung und die glazialen Chronologien nach wie vor differieren - insbesondere bezüglich der Rekonstruktion eines ehemaligen Gletschers im Indus-Tal. Verbesserte Datierungsmethoden revidieren hier ggf. bisherige Ansichten, und neuere Erklärungsmodelle, wie das „Wandern" des Monsun-Systems während des Quartärs als entscheidender regionaler Klimafaktor, versuchen asynchrone Chronologien zu verstehen.

description: For almost all the structures, concrete has been used as a basic and important construction material. It is made up of
the mixture of cement, coarse aggregate, fine aggregate and water. Its properties depend upon W/C ratio, humidity,
size of aggregate, type of components used, admixture used, amount of component used. While making a concrete
structure, it is very essential to prepare it to eliminate its major drawbacks such as poor workability, surplus
admixtures, honey combing of members, improper mixing. It should be kept in mind that these factors will affect the
entire structure and leads to the destruction. To access the condition of the structure, UPV tests are very popular Non
Destructive Test of concrete. This study deals with the UPV test procedure approach in Dry and Wet condition of
concrete specimen with the use of probe location on various fragments. The results of both pre and post curing of the
RCC block have been discussed in this paper with the recommendation of use of probe location. This study is
entirely concentrated on pre and post curing to know the hydration behavior of concrete after placing.

description: Building on a classical solution to the pentagon equation, constructed earlier by the author and E.V. Martyushev and related to the flat geometry invariant under the group SL(2), we construct an algebraic complex corresponding to a triangulation of a three-manifold. In case if this complex is acyclic (which is confirmed by examples), we use it for constructing a manifold invariant .

description: In order to stabilize yields in an Oxisol in Isabela, north coast of Puerto Rico, lime was applied yearly over a four-year period according to lime requirements determined by titration in CaCl,, to pH 6.0. Due to high soil variability, the land was divided into two-acre fields and analyses performed on composite samples from each. In some cases the variability was so high that these fields were further subdivided and the subdivisions analyzed separately for soil properties. While water pH values did not increase significantly in most areas, CaCl2 pH and yields did. In plots which showed particularly poor growth, numerous nodules high in manganese and iron were found. These plots corresponded to areas very high in Mehlich 3 extractable manganese and many were low in extractable zinc. Extractable manganese decreased steadily over the course of the study as yields increased. When problem areas were sidedressed with 560 kg ha- 1 lime, the corn and sunflowers recovered rapidly and gave good to reasonable yields.

description: Ever since Alfred R. Wallace suggested brightly coloured, toxic insects warn predators about their unprofitability, evolutionary biologists have searched for an explanation of how these aposematic prey evolve and are maintained in natural populations. Understanding how predators learn about this widespread prey defence is fundamental to addressing the problem, yet individuals differ in their foraging decisions and the predominant application of associative learning theory largely ignores predators' prior experience. Here we revisit the suggestion made almost 15 years ago that signal detection theory (SDT) provides a useful framework to model predator learning by emphasizing the integration of prior information into predation decisions. Using multiple experiments where we modified the availability of social information using video playback, we show that personal information (sampling aposematic prey) improves how predators (great tits, Parus major) discriminate between novel aposematic and cryptic prey. However, this relationship was not linear and beyond a certain point personal encounters with aposematic prey were no longer informative for prey discrimination. Social information about prey unpalatability reduced attacks on aposematic prey across learning trials, but it did not influence the relationship between personal sampling and discrimination. Our results suggest therefore that acquiring social information does not influence the value of personal information, but more experiments are needed to manipulate pay-offs and disentangle whether information sources affect response thresholds or change discrimination.This article is part of the theme issue ‘Signal detection theory in recognition systems: from evolving models to experimental tests’.
