Die Moordammkulturen des Amtsrates PAUL SCHREYER im Randow-Welse-Bruch
The bog sand-cover cultivations by Councilor PAUL SCHREYER in the Randow-Welse-Bruch

description: Abstract: The RIMPAU bog sand-cover cultivation was created in 1862 in the usually very shallow fens of the Drömling area. The objective had been to use these areas for agriculture. The shallowness of the fen made it possible to take the cover sand from the underground spreading it then on the dikes. For deep fen areas it became necessary to modify the process bringing in the sand from the mineral rim. However, difficulties arose from subsidence due to drainage and the sand load, the characteristics of the bog substrate and the grain size composition of the cover sand. Economic reasons, however, the agriculture bog sand-cover cultivation area was transformed into grassland. Today there are only a few examples of cultivated areas of this type left in their original shape. The bog sand-cover cultivations of SCHREYER in Wendemark may be considered an exception. The moderately deep to deep, highly degraded and nutrient-rich bog had been the deciding factor for creating the bog sand-cover cultivation. In the wake of collectivization of agriculture the bog sand-cover cultivations were filled in and large harvesting units were created. The location remained in fields und a transformation into grass land is not yet planned.
description: Zusammenfassung: Die RIMPAU‘sche Moordammkultur wurde im Jahre 1862 im überwiegend sehr flachgründigen Niedermoor des Drömling entwickelt. Ziel war es, hier Ackerbau betreiben zu können. Die Flachgründigkeit des Moores gestattete es, den Decksand aus dem Untergrund zu entnehmen und auf den Moordämmen zu verkarren. Für die tiefgründigen Moorstandorte war es erforderlich, das Verfahren dahingehend zu modifizieren, dass der Decksand aus dem Mineralrand herangeholt wurde. Probleme bereiteten hier bald die Moorsackung durch Entwässerung und Sandauflast, die Beschaffenheit der Moorsubstrate und die Korngrößenzusammensetzung des Decksandes. Ökonomische Gründe bewirkten jedoch, dass die Acker-Moordammkulturen in Grünland umgewandelt wurden. Es gibt heute nur noch wenige Beispiele, wo ein Originalzustand dieser Kulturen vorhanden ist. Eine Ausnahme sind die Moordammkulturen SCHREYER‘s in Wendemark. Das mitteltiefgründige, hochzersetzte und nährstoffreiche Moor war entscheidend für die Anlage der Acker-Moordammkulturen. Nach der Kollektivierung der Landwirtschaft wurden die Moordammgräben verfüllt und große Schlageinheiten eingerichtet. Die Standorte verblieben weiterhin in Ackernutzung und eine Umwandlung in Grünland war nicht vorgesehen.

description: Smoluchowski's equation is a macroscopic description of a many particle system with coagulation and shattering interactions. We give a microscopic model of the system from which we derive this equation rigorously. Provided the existence of a unique and sufficiently regular solution of Smoluchowski's equation, we prove the law of large numbers for the empirical processes. In contrast to previous derivations we assume a moderate scaling of the particle interaction, enabling us to estimate the critical fluctuation terms by using martingale inequalities. This approach can be justified in the regime of high temperatures and particle densities, which is of special interest in astrophysical studies and where previous derivations do not apply.

description: The optimized quantum $f$-divergences form a family of distinguishability measures that includes the quantum relative entropy and the sandwiched Rényi relative quasi-entropy as special cases. In this paper, we establish physically meaningful refinements of the data-processing inequality for the optimized $f$-divergence. In particular, the refinements state that the absolute difference between the optimized $f$-divergence and its channel-processed version is an upper bound on how well one can recover a quantum state acted upon by a quantum channel, whenever the recovery channel is taken to be a rotated Petz recovery channel. Not only do these results lead to physically meaningful refinements of the data-processing inequality for the sandwiched Rényi relative entropy, but they also have implications for perfect reversibility (i.e., quantum sufficiency) of the optimized $f$-divergences. Along the way, we improve upon previous physically meaningful refinements of the data-processing inequality for the standard $f$-divergence, as established in recent work of Carlen and Vershynina [arXiv:1710.02409, arXiv:1710.08080]. Finally, we extend the definition of the optimized $f$-divergence, its data-processing inequality, and all of our recoverability results to the general von Neumann algebraic setting, so that all of our results can be employed in physical settings beyond those confined to the most common finite-dimensional setting of interest in quantum information theory.

title: Developing a theory of the emotional impact of auditory hallucinations: an exploratory study
Creators: name: Close, Helen
Publisher: name: The Open University
Year: 1996

description: This research examines recent developments in the cognitive model of auditory hallucinations ("voices") in people with psychoses. Following the research of Chadwick and Birchwood (1994), data are presented on the behavioural, cognitive and affective responses to persistent voices of thirty participants with psychoses. After testing the reliability of their interview, data is then compared to that of the Chadwick and Birchwood (1994) sample. In addition, the research aimed to develop the cognitive model of the emotional impact of voices by examining further possible associations with participants' self-evaluations, hypothesising that these evaluations are associated with the affective response. The cognitive assessment of voices shows reasonable inter-rater and test re-test reliability. Compared to the Chadwick and Birchwood (1994) sample, the present sample had a greater proportion of negative affective responses to voices. regardless of their beliefs about the voices' benevolence or malevolence. Participants in this sample were less likely to endorse the voices' omnipotence or omniscience. Similarities were shown in behavioural responses and factors reported as proof of the voices' potential power. Although it was not possible to explore the associations between the content of voices, affective responses, self-evaluations and distress due to a preponderance of negative affective responses in this sample, nevertheless, it was possible to describe these responses. Participants in this sample had a predominantly negative content to their voices. Those who were able to access a personal meaning were found to have, predominantly, negative personal meanings, low self esteem and moderate distress as measured by standardised instruments.

It is performed in the dimuon decay channel, through the detection of muons with pseudorapidity $-4 < η_μ < -2.5$ and transverse momentum $p_{\rm T}^μ > 20$ GeV/$c$ in the laboratory frame. The invariant yield and nuclear modification factor are measured for opposite-sign dimuons with invariant mass $60 < m^{μμ} < 120$ GeV$c^2$ and rapidity $2.5 < y_{cms}^{μμ} < 4$. They are presented as a function of rapidity and, for the Pb-Pb collisions, of centrality as well. The results are compared with theoretical calculations, both with and without nuclear modifications to the Parton Distribution Functions (PDFs). In p-Pb collisions the center-of-mass frame is boosted with respect to the laboratory frame, and the measurements cover the backward ($-4.46< y_{cms}^{μμ}

NMDA receptor desensitization regulated by direct binding to PDZ1-2 domains of PSD-95
Creators: name: Sornarajah, Lavan
Publisher: name: University of British Columbia
Year: 2011

description: Regulation of NMDA receptor (NMDAR) activity by desensitization is important in physiological and pathological states; NMDAR desensitization contributes in shaping synaptic responses and may be protective by limiting calcium influx during sustained glutamate insults. We previously reported that glycine-independent desensitization decreases during hippocampal neuronal development, correlating with NMDAR synaptic localization and association with postsynaptic density 95 (PSD-95). PSD-95/Discs large/zona occludens (PDZ) domains 1 and 2 of PSD-95 bind to the C-terminus of NMDAR NR2 subunits. The role of PSD-95 in anchoring signaling proteins in close proximity to NMDARs is well documented. To determine if changes in NMDAR desensitization occur because of the direct binding of PSD-95 to NMDARs or due to PSD-95 recruitment of regulatory molecules, we tested the effects of various PSD-95 constructs on NMDAR currents in human embryonic kidney 293 (HEK293) cells and neurons. In HEK cells wild-type PSD-95 markedly reduced NMDAR desensitization, and the N-terminus of PSD- 95 truncated after the PDZ 1-2 domains was sufficient for this effect even when multimerization of PSD-95 was abolished. In immature neurons where PSD-95 expression is low, overexpression of either PSD-95 or PSD-95 PDZ 1-2 was sufficient to significantly decrease desensitization. In mature neurons, disruption of PSD-95/NMDAR interaction through protein kinase C (PKC) activation increased desensitization to levels found in immature neurons, and this effect was not due to direct regulation of NMDAR activity by PKC. We conclude that direct binding of PSD-95 increases stability of NMDAR responses to sustained agonist exposure in neuronal and non-neuronal cells.
QCD predictions for open charm meson production at the LHCb in fixed-target experiment

description: We investigate open charm meson production in fixed-target LHCb experiment at $\sqrt{s}=86.6$ GeV in $p+^4\!\mathrm{He}$ collisions. Theoretical calculations of charm cross section are done in the framework of the $k_{T}$-factorization approach. Its application in the kinematical range never examined before is carefully discussed. We consider different schemes for the calculations relevant for different unintegrated (transverse momentum dependent) parton densities in a proton. We include in the analysis both CCFM- and DGLAP-based models of unintegrated parton distributions appropriate for the considered kinematics. Integrated as well as differential cross sections as a function of $D^{0}$ meson rapidity and transverse momentum are shown and compared with the experimental data. As a reference point, predictions of next-to-leading order collinear approach are also presented and discussed. A very good agreement between the experimental data and the $k_{T}$-factorization predictions was obtained. Both the CCFM and the DGLAP-based frameworks for parton distributions in a proton are successfully used to explain the LHCb fixed-target open charm cross section.

description: Die Regenerationsfähigkeit vegetativer Sproßteilchen von sechs "Braunmoosen" wurde untersucht. Dabei zeigten sich bei allen Arten Teile des Hauptstämmchens und Ästchen sowohl vom "lebenden" Teil als auch von ± vertorften, "braun und tot erscheinenden" Teilen der Pflanze regenerationsfähig. Bei den beiden Calliergon-Arten waren aber auch die Blättchen regenerationsfähig. Da im Feld während fünf Vegetationsperioden alle Arten außer Campylium stellatum nie fruchtend gefunden wurden, dürfte den vegetativen Teilchen als Diasporen große Bedeutung zukommen.

At all species we found a more or less high rate of regeneration of the top or parts of the middle of the main stem and of branches respecitvely. At Galliergon giganteum and C. stramineum leaves could regenerate of new plants too. Therefore it is necessary to state that these parts of the plants are important as diaspores, because all species couldn't be found generatively reproducing during five years of field working except Campylium stellatum.

Abtorfungsverfahren und Wiedervernäßbarkeit
Peat cutting methods consistent with rewetting of the cutover area

Year: 1993

description: Die wichtigsten Torfabbauverfahren werden im Hinblick auf eine geplante Wiedervernässung bewertet. Die Sicherung der Bunkerde ist hierbei von großer Bedeutung; das kann heute bei jedem Verfahren technisch sichergestellt werden. Versuchsergebnisse zeigen, daß sich hochmoortypische Grund- bzw. Stauwasserstände in teilabgetorften Hochmooren erzielen lassen, in der ersten Phase nicht flächendeckend sondern in Vertiefungen beginnend, z.B. in ehemaligen Stechgräben bzw. künstlich geschaffenen Vertiefungen. Nur schwach bis mäßig zersetzte Bunkerden erfüllen die Anforderungen einer ausreichenden Wasserspeicherung. Bei stärker zersetzten Bunkerden ist eine ausreichende Vernässung in den Sommermonaten nur durch winterlichen Überstau möglich. Torfabbauverfahren, die nicht zu einer stärkeren Zersetzung der Bunkerde führen und ein Austrocknen der Bunkerde ausschließen, bieten die besten Voraussetzungen für eine anschließende Wiedervernässung, z.B. Weißtorfabbau im Stechverfahren, Abbau mittels Bagger bei nassem Unterfeld.
description: The main peat cutting methods are discussed with respect to the possibilities for rewetting of the cutover area. It is of great importance to save the surface layer material ("top spit = Bunkerde"); today this is possible with all peat cutting methods. The results of our field trials show positive effects of rewetting on partially cut raised bogs. At first, typical groundwater and perched water levels are not attained in all parts of the area but only in low areas, e.g. ditches. Only slightly or moderately decomposed surface material has sufficient water storage capacity for rewetting a cut bog. Strongly decomposed surface material is adequately wet in summer only if it is inundated in winter. Peat cutting methods that do not lead to significant decomposition of drying out of the surface material (e.g. the use of a sod peat cutting machine for Sphagnum peat or an excavator leaving a wet cutover field)provide the best conditions for rewetting afterwards.

description: This paper is intended as a contribution to a contemporary analysis of Black Philanthropy in the visual arts. Its purpose is to answer the central question: "How do Black Americans currently fund the visual arts?" while analyzing the conventional wisdom and deconstructing theories found within the European fundraising model--as it pertains to U.S. philanthropy in the visual arts. Contrary to Henry A. Rosso's canonical text Achieving Excellence, this paper's contemporary research concluded that contemporary Black philanthropy consists of heterogeneous funding. This thesis provides qualitative interviews and quantitative supporting data via survey to analyze the current trends in Black philanthropy and it anticipates future trends of Black philanthropy in the visual arts.

Especially we consider the most general two instanton solution given by the Jackiw-Nohl-Rebbi ansatz and find its dyonic version. By exploring the zeros of the Higgs field, we rederive the porism structure of triangles in this solution and also find the magnetic monopole string loop. This leads to the identification of dyonic instanton with the supertube inserted between D4 branes.

description: Trends in market regionalization, market globalization, open trade policies, and market availability facilitates increased trade of agricultural commodities, but implies increased risk for pest introduction and increased levels of pest tolerance. These changes require that the countries examine their phytosanitary status and collaborate to standardize phytosanitary permits. The World Trade Organization Agreement on the Application of Sanitary and Phytosanitary Measures (SPS) mandates the adoption of guidelines and requirements for agricultural trade. A country's responsibility for protecting itself and its trading partners from pests becomes more demanding as the level of international trade in agricultural products increases in volume and complexity. Thus, countries are trying to ensure that measures are in place to meet these requirements. At the same time, the SPS agreement ensures that the requirements are based on accurate scientific data, which are not readily available in all countries. On the other hand, resource limitations, downsizing, and continuous reorganization of agricultural quarantine, surveys and inspection programs are not always in keeping with the increased market trends. The expected outcome could be an increase in the number of pests introduced and established in the region. In Latin America and the Caribbean islands this problem is underscored by abundance of entry points, low number of phytosanitary personnel, limited access to equipment, technology, the lack or limited access to literature, and insufficient information on presence and distribution of pests in the region. The creation of the U.S. Department of Homeland Security supports activities that improve pest surveillance, early detection, rapid diagnostic of animal and plant diseases and pest threats, but the problem of invasive species persists. Knowledge of Latin America and the Caribbean islands strengths, weaknesses, and training needs will help to determine where the threats to American plant resources exist and what impact they could have if they enter the United States. In this paper, we present an analysis of the education, training and technical assistance requirements for protecting Latin America and the Caribbean and the U.S. from Invasive Species. The analysis contemplates existing training resources, the need for pest surveys, risk potential and assessment, eradication and management programs, and the need for a regional approach for invasive pest management.

description: We introduce the exceptional topological insulator (ETI), a non-Hermitian topological state of matter that features exotic non-Hermitian surface states which can only exist within the three-dimensional topological bulk embedding. We show how this phase can evolve from a Weyl semimetal or Hermitian three-dimensional topological insulator close to criticality when quasiparticles acquire a finite lifetime. The ETI does not require any symmetry to be stabilized. It is characterized by a bulk energy point gap, and exhibits robust surface states that cover the bulk gap as a single sheet of complex eigenvalues or with a single exceptional point. The ETI can be induced universally in gapless solid-state systems, thereby setting a paradigm for non-Hermitian topological matter.

description: Traditionally, the problem of invasive species, along with the decision-making framework established to prevent their introduction and spread, has been the domain of the biological scientific community. However, the scientific community is now calling for input by economics and other social science disciplines. The economic dimension of the problem of invasive species is growing from at least two perspectives. First, there is a greater awareness that economics is central to the causes of biological invasiveness, and that the consequences of pest incursions go far beyond direct damages or control costs. Second, modeling the economic and trade impact of regulations to combat the increased incidence of exotic pests and diseases, is becoming more important. This paper discusses the problem of invasive species from an economic perspective. It focuses on what economics has to do with the problem of biological invasiveness, and how the discipline can contribute to improving the decision-making framework.

description: Abstract: Environmental change and management activities were observed by means of a combined plot sub-catchment approach in forested areas with high share of degraded peat bogs in the upper Ore Mountains using the example of Carlsfeld watershed. The investigation focused on pathways and control factors of water and matter balance. Especially we discuss the parameter ‘Dissolved Organic Carbon (DOC)’ and ‘Spectral Absorption Coefficient at 254 nm (SAK254)’ in its time dynamic and spatial characteristic. The results represent basics for stakeholder interests of user and nature protection.
description: Zusammenfassung: Mittels eines kombinierten Standort-Kleinsteinzugsgebietsansatzes werden Umweltwandel und Maßnahmewirkungen in unterschiedlich degradierten und sich in Revitalisierung befindlichen Fichtenforsten mit hohem Anteil von Hochmooren in oberen Lagen des Erzgebirges am Beispiel Carlsfeld untersucht. Im Fokus stehen Pfade und Steuerungsfaktoren des Wasser- und Stoffhaushaltes. Insbesondere die Parameter „löslicher organischer Kohlenstoff (DOC)“ und „spektraler Absorptionskoeffizient bei 254 nm (SAK254)“ werden in zeitlicher Dynamik und räumlich vergleichend diskutiert. Die Ergebnisse stellen Grundlagen sowohl für wasser- und forstwirtschaftliche als auch klima- und naturschutzfachliche Interessensabwägungen dar.

description: The nicotinic acetylcholine receptor (nAChR) is the prototypic member of the `Cys-loop' superfamily of ligand-gated ion channels which mediate synaptic neurotransmission, and whose other members include receptors for glycine, gamma-aminobutyric acid, and serotonin. Cryo-electron microscopy has yielded a three dimensional structure of the nAChR in its closed state. However, the exact nature and location of the channel gate remains uncertain. Although the transmembrane pore is constricted close to its center, it is not completely occluded. Rather, the pore has a central hydrophobic zone of radius about 3 A. Model calculations suggest that such a constriction may form a hydrophobic gate, preventing movement of ions through a channel. We present a detailed and quantitative simulation study of the hydrophobic gating model of the nicotinic receptor, in order to fully evaluate this hypothesis. We demonstrate that the hydrophobic constriction of the nAChR pore indeed forms a closed gate. Potential of mean force (PMF) calculations reveal that the constriction presents a barrier of height ca. 10 kT to the permeation of sodium ions, placing an upper bound on the closed channel conductance of 0.3 pS. Thus, a 3 A radius hydrophobic pore can form a functional barrier to the permeation of a 1 A radius Na+ ion. Using a united atom force field for the protein instead of an all atom one retains the qualitative features but results in differing conductances, showing that the PMF is sensitive to the detailed molecular interactions.

description: Für die Torfgewinnung - wie für die Gewinnung von oberflächennahen Rohstoffen überhaupt - gibt es in den Landesnaturschutzgesetzen konkrete Genehmigungsvoraussetzungen und die generelle Vorgabe, daß ein Bodenabbau nur genehmigungsfähig ist, wenn der damit verbundene Eingriff in Natur und Landschaft wieder ausgeglichen werden kann. Diese gesetzlichen Rahmenbedingungen, verbunden mit den Erfahrungen mit der Genehmigungspraxis, gewährleisten ein Höchstmaß an Umweltverträglichkeit der Torfgewinnung. Darüber hinaus tragen geeignete Planungskonzepte und - last not least - technische Entwicklungen im Bereich der Torfgewinnung dazu bei, Natur und Landschaft bei der Rohstoffgewinnung zu schonen.
description: For the extraction of peat and for surface mining on the whole, existing Federal State Laws for nature conservation include precise preconditions for approval of extraction, the general precondition being that any effects on nature or the landscape must compensated for. These legal skeleton conditions combined with experiences made with the approving authorities ensure a maximum of environmentally compatible peat extraction. Furthermore, suitable detailed planning and - last not least - technical developments in peat production have contributed to indulgent treatment of nature and the landscape.

description: As part of a large-scale search for coherent pulsations from LMXBs in the RXTE archive, we have completed a detailed series of searches for coherent pulsations of 4U 1820-30 -- an ultracompact LMXB with a binary period of 11.4 minutes located in the globular cluster NGC6624. The small binary period leads to a very high acceleration, so we used phase modulation searches as well as acceleration searches to give significant sensitivity to millisecond pulsations. We searched a total of 34 archival RXTE observations, 32 of which had an on-source integration time longer than 10 ks, and some of which were made consecutively which allowed us to combine them. While we found no pulsations, we have been able to place the first stringent (95% confidence) pulsed fraction limits of < 0.8% for all realistic spin frequencies (i.e. < 1 kHz) and likely companion masses (0.02 Msun < Mc < 0.3 Msun). By contrast all five LMXBs known to emit coherent pulsations have intrinsic pulsed fractions in the range 3% to 7% when pulsations are observed.

description: Coffee production in the Caribbean and Latin America is an important commodity in terms of economic, ecological and social value. Coffee production in Puerto Rico was intensified in the 1960s, with a shift to higher-yield varieties, increased use of pesticides and fertilizers, increased mechanization, higher-density planting patterns, with production under full sunlight. There is concern that long-term, intensive coffee production under full sunlight may have a negative impact on agroecosystem sustainability. Soil physical, chemical and biological attributes from representative major coffee production regions in Puerto Rico under partial shade and full sunlight were quantified. Soils from secondary forests at least 25 years old were included for comparison. Soil fertility differed between forest and coffee agroecosystems with favorable soil reaction, improved nutrient reserves and availability in forested systems; coffee under shade had a tendency towards improved soil fertility. The soil physical structure was significantly affected by coffee production, with a greater proportion of large macroaggregates in forested sites than in coffee agroecosystems. Coffee under both partial shade and full sunlight had a lower proportion of macroaggregates and a higher proportion of microaggregates which may have important implications for the capacity of soils under coffee production to store C and release Ν for crops. Soil organic carbon and nitrogen, microbial biomass and fungal groups were negatively affected by coffee production, with few observed differences between coffee under shade and full sunlight. The soil biological community structure was negatively influenced by coffee production relative to secondary forested sites, with coffee under shade having slight improvement relative to coffee under sun.

description: This paper is intended as a contribution to a contemporary analysis of Black Philanthropy in the visual arts. Its purpose is to answer the central question: "How do Black Americans currently fund the visual arts?" while analyzing the conventional wisdom and deconstructing theories found within the European fundraising model--as it pertains to U.S. philanthropy in the visual arts. Contrary to Henry A. Rosso's canonical text Achieving Excellence, this paper's contemporary research concluded that contemporary Black philanthropy consists of heterogeneous funding. This thesis provides qualitative interviews and quantitative supporting data via survey to analyze the current trends in Black philanthropy and it anticipates future trends of Black philanthropy in the visual arts.

description: Dairy manure sludge (DMS) application to grazed forage pastures is a widespread agronomic practice. Unfortunately, the quantitative benefits of DMS application to improved pastures still has not been shown in the Caribbean. On-going application of DMS based on estimated nitrogen (N) content is unsustainable, and in many areas presents a threat to water quality, because the excess phosphorus (P) in dairy sludge is usually not extracted by plants and remains in soil until removed in runoff. Application of DMS based on Ρ content of the material may be a better alternative, but pastures may need to be supplemented with N. The nutrient concentration of DMS sludge in various farms of Puerto Rico was assessed. The mean (standard deviation in parenthesis) nutrient concentration of DMS (n=17) was 233 (120), 122 (77), 232 (123) mg/L for total N, total P, and total K, respectively. The economic benefit of DMS application, in terms of substitution for the price of nutrients in mineral fertilizer, could be from $79 to $158 per ha-cm (acre-in) of application, but the excess volume of DMS application from the improper application could offset potential agronomic and economic gains. Farmers applying DMS to fields should take every precaution to ensure that the infiltration rate of the soil is not exceeded and that during the application the volumes are kept to levels in which the nutrients applied do not exceed crop nutrient requirements. Further precautions include reducing the number of applications during the year and spreading the material to other areas of the farms. A case study demonstrated that there is an excess of nutrients generated on-farm which originate primarily from grazing animals, and is exacerbated by high animal densities, improper distribution of Ν and Ρ from DMS and fertilizer. Excess nutrients generated result in unsustainable nutrient rates to fields which could result in a waste of resources and environmental degradation.
