description: Induced Compton scattering (ICS) is an interaction between intense electro-magnetic radiations and plasmas, where ICS transfers the energy from photons to plasmas. Although ICS is important for laser plasma interactions in laboratory experiments and for radio emission from pulsars propagating in pulsar wind plasmas, the detail of photon cooling process has not been understood. The problem is that, when ICS dominates, evolution of photon spectra is described as a nonlinear convection equation, which makes photon spectra to be multi-valued. Here, we propose a new approach to treat evolution of photon spectra affected by ICS. Starting from the higher-order Kompaneets equation, we find a new equation that resolves the unphysical behavior of photon spectra. In addition, we find the steady-state analytic solution, which is linearly stable. We also successfully simulate the evolution of photon spectra without artificial viscosity. We find that photons rapidly lose their energy by ICS with continuously forming solitary structures in frequency-space. The solitary structures have the logarithmically same width characterized by an electron temperature. The energy transfer from photons to plasma is more effective for broader spectrum of photons such as expected in astrophysical situations.

description: Our study describes new methods for larval rearing of the red scorpionfish Scorpaena scrofa from hatching to 63 days post hatching (DPH). Eight adult wild specimens, including three females (Total Length = 40.63 ± 1.10 cm) and five males (Total Length = 42.46 ± 4.57 cm) were captured in 2013 to constitute the broodstock. On 2015, from June 16 to July 31, twenty-two spawning events were obtained. The fertilization percentage and the hatching rate were 65.71 ± 37.18% and 76 ± 3% respectively. From 0 to 63 DPH larvae grew from 2.18 ± 0.07 to 14.02 ± 1.21 mm.

description: RuP single crystals of MnP-type orthorhombic structure were synthesized by the Sn flux method. Temperature-dependent x-ray diffraction measurements reveal that the compound experiences two structural phase transitions, which are further confirmed by enormous anomalies shown in temperature-dependent resistivity and magnetic susceptibility. Particularly, the resistivity drops monotonically upon temperature cooling below the second transition, indicating that the material shows metallic behavior, in sharp contrast with the insulating ground state of polycrystalline samples. Optical conductivity measurements were also performed in order to unravel the mechanism of these two transitions. The measurement revealed a sudden reconstruction of band structure over a broad energy scale and a significant removal of conducting carriers below the first phase transition, while a charge-density-wave-like energy gap opens below the second phase transition.

description: Cloud computing is gaining popularity in the 3D Animation industry for rendering the 3D images. Rendering is an inevitable task in creating the 3d animated scenes. It is a process where the scene files to be animated is read and converted into 3D photorealistic images automatically. Since it is a computationally intensive task, this process consumes the majority of the time taken for 3D images production. As the scene files could be processed in parallel, clusters of computers called render farms can be used to speed up the rendering process. The advantage of using Cloud based render farms is that it is scalable and can be availed on demand. One of the important challenges faced by the 3D studios is the comparison and selection of the cloud based render farm service provider who could satisfy their functional and the non functional Quality of Service (QoS) requirements. In this paper we propose, a frame work for Cloud Service Broker (CSB) responsible for the selection and provision of the cloud based render farm. The Cloud Service Broker matches the functional and the non functional Quality of Service requirements (QoS) of the user with the service offerings of the render farm service providers and helps the user in selecting the right service provider using an aggregate utility function. The CSB also facilitates the process of Service Level Agreement (SLA) negotiation and monitoring by the third party monitoring services.

description: This is the first attempt to describe the relative growth of several characteristics in the deep-water rose shrimp Parapenaeus longirostris (Lucas, 1846) in the whole Mediterranean Sea. According to the median values, the morphometric characters of female and male individuals caught in the Aegean Sea were greater than those from the Ionian Sea. A negative allometry of swimming morphological characters (uropod, scaphocerite, telson) and of abdomen (related to the rapid locomotion, reproduction) was found in both sexes and areas. In contrast to this, the growth of the third pereiopod (involved in walking ability) in females from the Aegean Sea was positively allometric. Both sexes showed a positive allometry of rostrum length with size in both areas. The juveniles of both sexes showed proportionally longer morphological characters than the adult ones, indicating that the allometry differs for this species during its life cycle. The present study is of great interest to evolutionary biologists and to fishery managers providing an initial incentive for further investigation of this commercially important decapod in the whole Mediterranean.

Recent amendments to the Medicaid program: political implications.

description: Medicaid has never been a popular program. It has from its inception been an expensive social commitment, demanding larger, although not always proportionately larger, shares of the state and federal budgets for nearly two decades. It has been saddled with a welfare-designed structure, thereby ensuring inherent inequities in the distribution of benefits. It lacks the support of an enfranchised constituency; indeed, in pragmatic terms, the only true Medicaid constituency is made up of the state governments which distribute Medicaid funds and the medical care providers who receive them-support which is largely for the purpose of securing the flow of those funds, not for the achievement of Medicaid's programmatic goals.

description: The movies like the Avatar are a good example of the stunning visual effects that the animation could bring into a movie.The 3D wire frame models are converted to 3D photo realistic images using a process called the rendering. This rendering process is offered as a service in the cloud, where the animation files to be rendered are split into frames and rendered in the cloud resources and are popularly known as Rendering as a Service. As this is gaining high popularity among the animators community, this work intends to enable the animators to Gain basic knowledge about Rendering as a Service. Understand the variety in the service models through the taxonomy,Explore, compare and classify the services quickly using the tree-structured taxonomy of services. In this paper, the various characteristics of the services are organized in the form of a tree to enable quick classification and comparison of the services. To enhance the understandability, three popular services have been classified and verified according to the proposed tree-structured taxonomy.

description: As the initial step in a five-year project to improve control of high blood pressure in Edgecombe County, North Carolina, a survey was conducted in 1980 to determine the prevalence of hypertension and to identify factors which might constitute barriers to the use of medical care by hypertensives. This report summarizes the findings for the 539 hypertensives identified through the baseline survey. In general, Black hypertensives reported more access problems than Whites. Within race, however, males and females differed very little on selected measures of potential access to medical care. Among women, lower scores on potential access were strongly associated with being untreated, whereas for men, concerns about the safety of anti-hypertensive drug therapy were associated with being unaware. On a summary measure of the actual use of medical care in response to symptoms, both male and female treated hypertensives scored higher than their untreated counterparts. The implications of these and other findings for community-based blood pressure control activities are discussed.

description: The complexity of a module is an important homological invariant that measures the polynomial rate of growth of its minimal projective resolution. For the symmetric group $Σ_n$, the Lie module $\mathsf{Lie}(n)$ has attracted a great deal of interest in recent years. We prove here that the complexity of $\mathsf{Lie}(n)$ in characteristic $p$ is $t$ where $p^t$ is the largest power of $p$ dividing $n$, thus proving a conjecture of Erdmann, Lim and Tan. The proof uses work of Arone and Kankaanrinta which describes the homology $\operatorname{H}_\bullet(Σ_n, \mathsf{Lie}(n))$ and earlier work of Hemmer and Nakano on complexity for modules over $Σ_n$ that involves restriction to Young subgroups.

title: Interfaces in all-oxide thin-film varactors with highly-conducting SrMoO3 electrodes for microwave applications
Creators: name: Salg, Patrick
Publisher: name: UNSPECIFIED
Year: 2020

description: In this work, the interfaces and growth by pulsed laser deposition of the all-oxide varactor heterostructurewas investigated. This all-oxide varactor heterostructure consists of SrMoO3/(Ba,Sr)TiO3/Pt/Au layers and has several advantages over thin-film varactors with Pt bottom electrodes such as defect free, epitaxial growth. Furthermore, new interface materials and optimized growth led to an improvement of the all-oxide varactor microwave performance beyond the level of competing state-of-the-art platinum-based technology. A key achievement for this performance increase was the fast and several micrometer thick growth of the bottom electrode SrMoO3. Although grown at a exceptional high rate of 1 µm SMO in only 45 minutes, the bottom electrode exhibits a high conductivity, low defect density, and atomically flat interface to the dielectric layer. The influence of different substrates with varying in-plane lattice constants on the SrMoO3 growth was also investigated, including the industrially relevant substrate silicon. Epitaxial growth has been realized for silicon and a wide range of scandates, proven by reciprocal space maps. In order to unite the the reductive growth conditions of the bottom electrode with the oxidizing background pressure during the growth of the dielectric, a oxygen diffusion barrier is implemented. In order to find the best performing titanate compound, in terms of oxygen diffusion barrier, a novel measurement routine was established utilizing X-ray photoelectron spectroscopy. In addition to comparisons of the different titanate compounds, quantitative diffusion barrier limits for best performing compound, Ba0.5Sr0.5TiO3, such as temperature and background pressure were determined. This enabled the growth of the dielectric at higher oxygen partial pressures leading to a sufficient oxygenation of the dielectric layer and a decrease of the leakage current of several orders of magnitude. The findings were combined in high-performance all-oxide varactor heterostructures both on the GdScO3 and silicon substrates. In summary, fast and micrometer-thick growth of SrMoO3 and a novel oxygen diffusion barrier were established and could raise the performance of all-oxide varactors and demonstrate the feasibility of this technology for microwave applications.

description: Das untere Elbtal hat während der Weichsel-Kaltzeit (120.000-10.000 vor heute) als nordwestliche Fortsetzung der drei großen mitteldeutschen und polnischen Urstromtäler gedient (GIRARD 1855). Die drei Urstromtäler sind jeweils der Haupteisrandlage einer Vereisungsphase zuzuordnen und nacheinander in Funktion gewesen (KEILHACK 1887, 1898). Die drei Urstromtäler vereinigen sich nahe dem Elbknie bei Havelberg. Von dort aus sind die Schmelzwässer des skandinavischen Inlandeises gemeinsam mit den Flußwässern aus dem mitteldeutschen Einzuggebiet der Elbe zur Nordsee abgeflossen. Dazugekommen sind Schmelzwasserabflüsse vom Eisrand, der während des Höchststandes der Vereisung nur etwa 10 km vom Elbtal entfernt gelegen hat. Trotz der wichtigen Funktion des Elbe-Urstromtales bei der Entwässerung Mitteleuropas hat es bisher keine zusammenfassende Bearbeitung der weichselkaltzeitlichen Urstromtal - Ablagerungen gegeben. Ausgangspunkt für die vorliegende Arbeit ist die Frage gewesen, ob sich die weichselkaltzeitlichen Urstromtalabiagerungen, die als Niederterrassen-Ablagerungen bezeichnet werden, petrographisch von liegenden Schichteinheiten abtrennen lassen. Weitere thematische Schwerpunkte sind die Anlage und Entwicklung des Elbe-Urstromtales sowie die Untergliederung der dazugehörigen Sedimente. Geographischer Ausgangspunkt der Untersuchungen ist der Raum Gorleben. Dort wurde die kiespetrographische Gliederung der quartären Schichten erarbeitet, unter maßgeblicher Mitwirkung von Frau Dipl.-Geol. C. KABEL (in Duphorn 1980, 1983). Von Gorleben aus wird der Verlauf der Niederterrasse anhand von 11 Querprofilen bis in die Deutsche Bucht verfolgt.

description: We present a comprehensive methodology for the simulation of astronomical images from optical survey telescopes. We use a photon Monte Carlo approach to construct images by sampling photons from models of astronomical source populations, and then simulating those photons through the system as they interact with the atmosphere, telescope, and camera. We demonstrate that all physical effects for optical light that determine the shapes, locations, and brightnesses of individual stars and galaxies can be accurately represented in this formalism. By using large scale grid computing, modern processors, and an efficient implementation that can produce 400,000 photons/second, we demonstrate that even very large optical surveys can be now be simulated. We demonstrate that we are able to: 1) construct kilometer scale phase screens necessary for wide-field telescopes, 2) reproduce atmospheric point-spread-function moments using a fast novel hybrid geometric/Fourier technique for non-diffraction limited telescopes, 3) accurately reproduce the expected spot diagrams for complex aspheric optical designs, and 4) recover system effective area predicted from analytic photometry integrals. This new code, the photon simulator (PhoSim), is publicly available. We have implemented the Large Synoptic Survey Telescope (LSST) design, and it can be extended to other telescopes. We expect that because of the comprehensive physics implemented in PhoSim, it will be used by the community to plan future observations, interpret detailed existing observations, and quantify systematics related to various astronomical measurements. Future development and validation by comparisons with real data will continue to improve the fidelity and usability of the code.

description: Subsidized rural clinics and providers have long depended on the rural hospital for the care of some of their patients; the hospital has also been a source of revenue for these providers and programs. We studied a representative national sample of 116 subsidized rural clinics, focusing on the impact on rural clinic costs and revenues of the use of the hospital by the clinics' providers. Both clinic costs and revenue are reduced by the use of the hospital by rural practice providers, but costs are lowered to a greater extent than revenues, thereby enhancing the financial self-sufficiency of the subsidized clinic. The cost savings affect all aspects of clinic operation, but especially laboratory costs, community services costs, and administrative costs. The dependence of these rural clinics on the hospital indicates that the condition of subsidized rural clinics would be worsened by decreased availability of hospital services.

description: Three new species of Echinoderes (Kinorhyncha: Cyclorhagida: Echinoderidae) are described from two Northeast Atlantic seamounts and the adjacent deep-sea floor. Echinoderes apex sp. nov. from the Great Meteor Seamount and the Sedlo Seamount is characterized by a combination of: a small trunk length (165-215 Vm); middorsal acicular spines on segments 4, 6, and 8; tubes ventrolaterally on segment 2, lateroventrally on segment 5, and laterodorsally on segment 10; lateroventral acicular spines on segments 6-9; long lateral terminal spines, 60.0-80.2% of trunk length; and type-2 glan- dular cell outlets subdorsally on segment 2, sublaterally on segment 6, and lateral accessorily on segment 8. Echinoderes bathyalis sp. nov. from the deep-sea floor near the Sedlo Seamount is characterized by a combination of: a small trunk length (224-243 Vm); middorsal acicular spines on segments 4-8 with a spine on segment 8 being very long (ca. 50% of trunk length); lateral accessory tubes on segment 5; lateroventral acicular spines on segments 6-9; and type-2 glandular cell outlets midlaterally on segment 2. Echinoderes meteorensis sp. nov. from the Great Meteor Seamount differs from its con- geners in a combination of: a small trunk length (157-196 Vm); presence of middorsal acicular spines on segments 4, 6, and 8; tubes lateroventrally on segment 5, lateral accessorily on segment 8, and laterodorsally on segment 10; lateroventral aci- cular spines on segments 6-9; and type-2 glandular cell outlets in subdorsal and lateral accessory positions on segment 2. Echinoderes apex occurs on two seamount summits, whereas E. meteorensis occurs on one seamount summit, and no species occur both on a seamount summit and on the deep-sea floor.
Coital and non-coital sexual behaviors of white and black adolescents.

description: As part of a longitudinal study of young adolescents, data were collected in 1980 on the non-coital and coital sexual experiences of male and female adolescents who ranged in age from 12 to 15 at the time of the initial contact. The follow-up data were collected two years later. Both a Guttman's scale analysis and a longitudinal analysis of these data indicate different sexual patterns between White and Black teens; Whites are more likely than Blacks to engage in a predictable series of non-coital behaviors for a period of time before their first intercourse experience. Of the sexual behaviors studied, the pre-coital experiences of Black teens were less predictable and often involved only necking. These differences in sexual norms offer a partial explanation for the different pregnancy rates between these two groups. They also suggest that sexual and contraceptive education and counseling need to be cognizant of these differences since pre-coital experience may function as both a mechanism to prolong abstinence and to promote a gradual acceptance of one's sexuality.

description: Im niedersächsischen Teil des Osnabrücker Berglands wurde der Muschelkalk lithostratigraphisch untersucht und sein Gesteinsinventar im Hinblick auf dessen Eignung für die Herstellung von Straßenbaumaterial sowie andere Nutzungsmöglichkeiten überprüft. Die methodischen Schwerpunkte lagen bei der Aufschluß-Bearbeitung, der Ermittlung technologischer Kennwerte nach den einschlägigen Prüf-Vorschriften für Straßenbaustoffe und der Bestimmung der durchschnittlichen geochemischen Zusammensetzung von Teilschichtfolgen mittels RFA-Analysen. Durch geologische Aufnahme und Korrelation von zahlreichen Tagesaufschlüssen und zwei Kernbohrungen gelang es, eine detaillierte lithostratigraphische Regionalgliederung des ca. 80 m mächtigen Unteren Muschelkalks für den Raum Osnabrück zu erarbeiten. Eine von DUCHROW & GROETZNER (1984) publizierte lithostratigraphische Gliederung des Oberen Muschelkalks (ca. 60 m mächtig) im Arbeitsgebiet erwies sich als nachvollziehbar und wird auch in Gamma- Ray-Logs aus Bohrungen deutlich. Die Interpretation der geologischen Befunde ergab, daß die 1ithofaziellen Voraussetzungen für den Hartsteinabbau im Oberen Muschelkalk am günstigsten im Raum SW Osnabrücks sind. Nach den Ergebnissen der technologischen Untersuchungen sind nicht nur die zur Zeit bereits im Abbau stehenden, dickbankigen, sehr karbonatreichen Einschaltungen in den Oberen Muschelkalk (Haupt-Trochitenkalk, Terebratelkalk) für die Herstellung von Straßenbaumaterial geeignet, sondern mit einigen Einschränkungen auch der hierfür bisher nicht genutzte Untere Muschelkalk und die Gelben Basisschichten (Oberer Muschelkalk). Der Abbau und Einsatz dieses Gesteinsmaterials im Straßen- und Wegebau kann einen wichtigen Beitrag zur Streckung der nur noch geringen Vorräte an hochwertigem Kalkstein liefern. Die Gesteine des Unteren Muschelkalks und der Gelben Basisschichten (Oberer Muschelkalk) sind darüber hinaus aufgrund ihrer geochemischen Zusammensetzung ein gutes Rohmaterial für die Herstellung von "Kohlensaurem Kalk" und "Kohlensaurem Magnesiumkalk". Diese Produkte werden in zunehmendem Maße in der Forst- und Landwirtschaft eingesetzt, um durch saure Niederschläge hervorgerufene Vegetationsschäden zu begrenzen.

description: This work describes the ectoparasitic fauna -with a special focus to their microhabitat - of the European eel. During a three year study, 450 Anguilla anguilla gill infracommunities were studied in lake Oubeïra (NE of Algeria) to determine whether parasite infrapopulations interact. Three levels were retained: the epidemiological trends, the preference of species on gills, different arches and niche breadth/niche overlap between species. Two crustaceans: Ergasilus gibbus (6199), Argulus foliaceus (180) and one monogenean Pseudodactylogyrus sp. (495) were found. All species exhibited microhabitat preference for II and III gill-arches but no preference for either side of the fish. In addition, Argulus foliaceus showed niche restriction that is probably due to gregarious behavior of Pseudodactylogyrus sp. Lastly, the use of principal component analysis reveals the affinity of Ergasilus gibbus and Pseudodactylogyrus sp. for the largest host contrary to Argulus foliaceus.

description: Innerhalb des Lippischen Berglandes in Ostwestfalen sind vereinzelte tertiärzeitliche Vorkommen bis heute erhalten geblieben. Die bekanntesten Lokalitäten sind dort die aufgelassene Quarzsandgrube von Dörentrup und die alten Fossilfundpunkte für das Oberoligozän in Friedrichsfeld und Göttentrup. Zur Gesamtdarstellung des rund 7 km2 großen Tertiär-Vorkommens wurden rund 200 Bohrungen in verschiedenen Archiven aus den Jahren 1861 bis 1986 gesichtet und durch ein Bohrprogramm mit 67 Bohrungen (1 270,4 lfd. m), das v. Verf. in den Jahren 1981 bis 1984 vor Ort betreut und geologisch ausgewertet wurde, ergänzt. Hinzu kam die Aufnahme von 85 Aufschlüssen im Locker- und Festgestein. Das Tertiär von Dörentrup liegt in einem durch Subrosion zechsteinzeitlicher Salinargesteine in mehreren Senkungsphasen (Alttertiär bis Mittelpleistozän) entstandenen Senkungsfeld, das im Bereich tektonisch vorgezeichneter Schwächezonen zwischen den Großstrukturen Niedersächsisches Tektogen und Hessische Senke entstanden ist. Die Schichtenfolge des Tertiärs lagert dem mesozoischen Untergrund (Keuper, Lias) diskordant auf. Sie beginnt mit dem Unteroligozän. Mittel- und oberoligozäne Sedimente sind ebenfalls durch weitere Bohrungen nachgewiesen. Ihre lithologische Ausbildung und die Fossilführung zeigen marine Verhältnisse und Landnähe an. Das Oligozän wird von einer Geröllage mit überwiegend Kieselschiefer- und Quarzgeröllen nach oben abgeschlossen. Die Maximalmächtigkeit des Oligozäns beträgt 73 m. Die fluviatilen sandigen Ablagerungen mit eingeschalteten Tonen und gering inkohlten Braunkohlenflözen sind pollenanalytisch in das Miozän/Pliozän zu stellen. Korngrößenanalysen und granulometrische Parameter zeigen zwei Sedimenteinheiten auf: schluffige Feinsande im älteren Teil und sehr eisenarme Mittelsande mit einzelnen Grobsandlagen ("Dörentruper Quarzsand") im jüngeren Teil. Das Quartär erreicht Mächtigkeiten von über 60 m, die durch eine subrosive Absenkung während der Sedimentation ermöglicht wurden. Die mio-/pliozänen Sedimentproben aus den Aufschlüssen besitzen Durchlässigkeitsbeiwerte von 9,4 x 10-4 bis 5,3 x 10-5 m/s. Eine geologische Profilserie mit 18 Profilschnitten durch das Tertiär-Vorkommen verdeutlicht die komplizierten Lagerungsverhältnisse.

description: We use the Hirsch-Fye quantum Monte Carlo method to study the single magnetic impurity problem in a two-dimensional electron gas with Rashba spin-orbit coupling. We calculate the spin susceptibility for various values of spin-orbit coupling, Hubbard interaction, and chemical potential. The Kondo temperatures for different parameters are estimated by fitting the universal curves of spin susceptibility. We find that the Kondo temperature is almost a linear function of Rashba spin-orbit energy when the chemical potential is close to the edge of the conduction band. When the chemical potential is far away from the band edge, the Kondo temperature is independent of the spin-orbit coupling. These results demonstrate that, for single impurity problem in this system, the most important reason to change the Kondo temperature is the divergence of density of states near the band edge, and the divergence is induced by the Rashba spin-orbit coupling.

description: In der vorliegenden Arbeit wird die Entwicklung eines lichtbasierten Fahrerassistenzsystems mittels Projektionen auf der Fahrbahn beschrieben. Unter realitätsnahen Bedingungen zeigt sich, dass Informationsübertragung an den Fahrer bei Nacht mittels Projektionen vor dem Fahrzeug möglich ist: Probanden fahren sicherer durch Engstellen und reagieren früher auf Hindernisse. Durch einen straßentauglichen Prototyp wird die seriennahe Umsetzung eines solchen Scheinwerfer-Projektionssystems gezeigt.

description: 41 samples which have been collected from the Lower Cretaceous section Moorberg/Sarstedt (Lower Hauterivian-Lower Barremian) have been investigated for calcareous Nannoplankton. About 4500 coccoliths have been measured, most of which are determinated as Biscutum constans, Bidiscus rotatorius, Corollithion geometricum, Cyclagelosphaera margereli, Parhabdolithus asper and Sollasites horticus. These dates are evaluated and partly graphically represented. Within the paleontological part 4 5 species are described and partly illustrated by photos and drawings. 2 new species (Chiastozygus octiformis and Chiastozygus tripes) are introduced, while one genus and one species are emended. Based on 18350 countered specimens the relative quantity of 68 species is shown, 15 of which got stratigraphical signifi- cance for NW-Germany and possible further around. According to the calcareous Nannoplankton the connection of the "boreal realm" and the Tethys should have been interrupted already in the lowermost Upper Hauterivian.
description: Aus dem orthostratigraphischen (nach Ammoniten) gegliederten Profil von Moorberg/Sarstedt des Unter-Hauterivium bis Unter- Barremium werden 41 Proben auf kalkiges Nannoplankton hin untersucht. Es werden 4500 Coccolithen vermessen; ein Großteil dieser Zahl verteilt sich auf 6 Arten (Biscutum constans, Bidiscus rotatorius, Corollithion geometricum, Cyclagelosphaera margere- li, Parhabdolithus asper und Sollasites horticus). Diese Meßdaten werden ausgewertet und z.T. graphisch dargestellt 45 Arten werden im paläontologischen Teil erfaßt und teilweise mit Fotos und Zeichnungen versehen. Es werden zwei neue Arten aufgestellt: Chiastozygus octiformis und Chiastozygus tripes. Eine Gattung und eine Art werden emen- diert. Aufgrund von 18350 ausgezählten Exemplaren, die sich auf 68 Arten verteilen, wird die relative Häufigkeit dargestellt Die biostratigraphische Bewertung ergibt, daß davon 15 Arten für den NW-deutschen Raum und evtl, darüber hinaus bedeutsam sind. Die palökologische Auswertung zeigt, daß nach kalkigem Nannoplankton bereits an der Grenze Unter-/Ober-Hauterivium die Meeresverbindung mit der Tethys unterbrochen sein mußte.

description: In a rural, church-based hypertension program in Edgecombe County, North Carolina, screening of the congregations was complemented by a community outreach component targeted at 18-60 year old males, a group at higher risk for untreated hypertension. Compared with its estimated frequency in the community, untreated hypertension was as common in the church congregations and somewhat less prevalent than expected among outreach screenees.

description: We study a harmonic system coupled to chain of first neighbor interacting oscillators. After deriving the exact dynamics of the system, we prove that one can effectively describe the exact dynamics by considering a suitable shorter chain. We provide the explicit expression for such an effective dynamics and we provide an upper bound on the error one makes considering it instead of the dynamics of the full chain. We eventually prove how error, timescale and number of modes in the truncated chain are related.

description: In this dental survey of a multi-disability sheltered industry, 233 adults were examined. When compared to adjusted North Carolina values, the workers exhibited poorer oral hygiene with higher rates and severity of periodontal disease. DMF-T totals were equal to those statewide; however, workers had more decayed and fewer missing teeth. Significant unmet restorative and prosthodontic needs were found. Treatment cost estimates at 1983 fees were $421 per capita, with a median fee of $240.
