description: The aim of this study was to perform a systematic review and meta-analysis on randomized controlled trials investigating the effects of carotenoids on selected inflammatory parameters. PubMed, SCOPUS, and Web of science were searched from inception until April 2021. The random-effect model was used to analyze data and the overall effect size was computed as weighted mean difference (WMD) and corresponding 95% of confidence interval (CI). A total of 26 trials with 35 effect sizes were included in this meta-analysis. The results indicated significant effects of carotenoids on C-reactive protein (CRP) (WMD: ‒0.54 mg/L, 95% CI: ‒0.71, ‒0.37, P < 0.001), and interleukin-6 (IL-6) (WMD: ‒0.54 pg/mL, 95% CI: ‒1.01, ‒0.06, P = 0.025), however the effect on tumor necrosis factor-alpha (TNF-α) was not significant (WMD: ‒0.97 pg/ml, 95% CI: ‒1.98, 0.03, P = 0.0.059). For the individual carotenoids, astaxanthin, (WMD: ‒0.30 mg/L, 95% CI: ‒0.51, ‒0.09, P = 0.005), lutein/zeaxanthin (WMD: ‒0.30 mg/L, 95% CI: ‒0.45, ‒0.15, P < 0.001), and β-cryptoxanthin (WMD: ‒0.35 mg/L, 95% CI: ‒0.54, ‒0.15, P < 0.001) significantly decreased CRP level. Also, only lycopene (WMD: ‒1.08 pg/ml, 95%CI: ‒2.03, ‒0.12, P = 0.027) led to a significant decrease in IL-6. The overall results supported possible protective effects of carotenoids on inflammatory biomarkers.
title: The effect of gases on the electrical properties of some organic semiconductors
Creators: name: van Ewyk, Robert L
Publisher: name: University of Kent
Year: 2022

description: Effects of gases (primarily NgO^, BF^, Og and NH^) on the electrical properties of molecular single crystals of donors (phthalocyanine and its Mn(ll), Co(ll), Ni(ll), Cu(ll), Zn(ll) and Ph(ll) complexes, anthracene, perylene and the bis(8-hydroxyquinoline) complexes of Cu(ll) and Pd(ll)), electron acceptor (7,7,8,8 tetraeyanoquinodimethane) and an electron donor-acceptor complex (perylene/7,7,8,8 tetracyanoquinodimethane) have been studied. Apparatus was constructed permitting measurement of semiconduction and photoconduction in vacuo and in various gas pressures, over a temperature range of 290-500K. The conductivity of electron donor and acceptor crystals was only enhanced by electron acceptor and donor gases, respectively, whereas the donor-acceptor complexes were enhanced slightly by both types of gases. Gas effects were confined to the crystal surfaces, except for oxygen on phthalocyanines. The rate and magnitude of conductivity changes on varying the gas pressure were consistent with chemisorption involving electron transfer. Electron transfer between % delocalised orbitals (e.g. NgO^ on phthalocyanines) gave reversible adsorption and gas pressures above 10^Pa resulted in complete surface coverage, each adsorbed molecule producing one surface charge carrier. The more localised c orbitals (e.g. BF-^ on phthalo- cyanineB) resulted in stronger adsorption. Exceptionally, irreversible chemical reaction follows electron transfer (e.g. NgO^ on anthracene). Enhanced semiconduction is accompanied by significant reductions in the activation energy, to values comparable with the photoconduction activation energy. Photoconduction is more sensitive than semiconduction to low gas pressures. Changes in the photoconduction spectral response reflect the influence of adsorbed gases on the exciton dissociation process. Adsorbed NgO^ inhibits the singlet photoconduction in tetracyanoquinodimethane and perylene, but smaller low energy response, with fine structure, possibly triplet bulk photoconduction, persists. Increased surface ionized state density reduces the carrier mobility, resulting in reduced dependence of photocurrent on incident light intensity. The implications of these findings for the design of organic semiconductor gas detectors are discussed.

description: In this paper we describe a perfect simulation algorithm for the stable $M/G/c$ queue. Sigman (2011: Exact Simulation of the Stationary Distribution of the FIFO M/G/c Queue. Journal of Applied Probability, 48A, 209--213) showed how to build a dominated CFTP algorithm for perfect simulation of the super-stable $M/G/c$ queue operating under First Come First Served discipline, with dominating process provided by the corresponding $M/G/1$ queue (using Wolff's sample path monotonicity, which applies when service durations are coupled in order of initiation of service), and exploiting the fact that the workload process for the $M/G/1$ queue remains the same under different queueing disciplines, in particular under the Processor Sharing discipline, for which a dynamic reversibility property holds. We generalize Sigman's construction to the stable case by comparing the $M/G/c$ queue to a copy run under Random Assignment. This allows us to produce a naive perfect simulation algorithm based on running the dominating process back to the time it first empties. We also construct a more efficient algorithm that uses sandwiching by lower and upper processes constructed as coupled $M/G/c$ queues started respectively from the empty state and the state of the $M/G/c$ queue under Random Assignment. A careful analysis shows that appropriate ordering relationships can still be maintained, so long as service durations continue to be coupled in order of initiation of service. We summarize statistical checks of simulation output, and demonstrate that the mean run-time is finite so long as the second moment of the service duration distribution is finite.

description: This study aimed to investigate the impact of performing neurotization during breast reconstruction on total operating time and post-operative morbidity. The 2015 through 2019 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) databases were utilized to identify patients who underwent breast reconstruction with and without neurotization. Baseline demographics, comorbidities, operative characteristics and outcomes were examined for each group. Thirty-day complication and readmission rates were compared using univariable and multivariable logistic regressions. Of 73,507 patients identified who underwent breast reconstruction, 240 had reconstruction with neurotization. Autologous reconstruction was more prevalent for patients with neurotization (90.8% vs. 18.5%, p<.001). Average operating time was longer when neurotization was performed during both autologous (527.1 ± 152.4 vs. 414.8 ± 186.3, p<.001) and alloplastic-only reconstruction (310.9 ± 115.9 vs. 173.0 ± 94.3, p<.001). The likelihood total operating time exceeded 521 min (two standard deviations above average) increased when neurotization was performed (OR 2.464, CI 1.864–3.255, p<.001). Thirty-day complications occurred in 13.8% of patients with neurotization and 6.8% without (p<.001). Similarly, 30-day readmission rates were higher for patients with neurotization (7.5% vs. 4.2%, p<.001). However, when adjusted for comorbidities and operative characteristics, neurotization did not significantly impact 30-day complication rates (OR 0.802, CI 0.548–1.174, p=.256) or 30-day readmission rates (OR 1.352, CI 0.822–2.223, p=.077). Although neurotization during breast reconstruction increases operating time, comorbidities and procedural characteristics play a greater role in post-operative outcomes than neurotization alone.

description: We present a Bayesian model for area-level count data that uses Gaussian random effects with a novel type of G-Wishart prior on the inverse variance--covariance matrix. Specifically, we introduce a new distribution called the truncated G-Wishart distribution that has support over precision matrices that lead to positive associations between the random effects of neighboring regions while preserving conditional independence of non-neighboring regions. We describe Markov chain Monte Carlo sampling algorithms for the truncated G-Wishart prior in a disease mapping context and compare our results to Bayesian hierarchical models based on intrinsic autoregression priors. A simulation study illustrates that using the truncated G-Wishart prior improves over the intrinsic autoregressive priors when there are discontinuities in the disease risk surface. The new model is applied to an analysis of cancer incidence data in Washington State.

description: The finite and infinite square wells are potentials typically discussed in undergraduate quantum mechanics courses. In this paper, we discuss these potentials in the light of the recent studies of the modification of the Heisenberg uncertainty principle into a generalized uncertainty principle as a consequence of attempts to formulate a quantum theory of gravity. The fundamental concepts of the minimal length scale and the generalized uncertainty principle are discussed and the modified energy eigenvalues and transmission coefficient are derived.

description: Under some assumptions on the hierarchy of relevant energy scales, we compute the nonrelativistic QCD (NRQCD) long-distance matrix elements (LDMEs) for inclusive production of $J/ψ$, $ψ(2S)$, and $Υ$ states based on the potential NRQCD (pNRQCD) effective field theory. Based on the pNRQCD formalism, we obtain expressions for the LDMEs in terms of the quarkonium wavefunctions at the origin and universal gluonic correlators, which do not depend on the heavy quark flavor or the radial excitation. This greatly reduces the number of nonperturbative unknowns and substantially enhances the predictive power of the nonrelativistic effective field theory formalism. We obtain improved determinations of the LDMEs for $J/ψ$, $ψ(2S)$, and $Υ$ states thanks to the universality of the gluonic correlators, and obtain phenomenological results for cross sections and polarizations at large transverse momentum that agree well with measurements at the LHC.

description: High-throughput platforms that can potentially generate substantial quantities of corneal grafts will be invaluable in addressing the existing global demand for keratoplasty. Slaughterhouses generate substantial quantities of underutilized biological waste that can be repurposed to reduce current environmentally unfriendly practices. Such efforts to support sustainability can simultaneously drive the development of transplantable ovine corneas and patient-specific bioartificial keratoprostheses. This study presents a dataset highlighting techniques that evaluated the development of a simplified, inexpensive, and high-throughput corneal xenograft platform. To our knowledge, this is the first dataset to be generated in the United Arab Emirates, outlining a platform that can produce dozens of native ovine xenografts and acellular corneal scaffolds that effectively preserve ocular transparency, transmittance, and ECM components. Such native grafts can then be genetically modified to reduce rejection and retrovirus transmission in recipients. Analogously, decellularization technologies can support corneal regeneration with attributes comparable to native xenografts.

description: Ein Opfer der Ungarneinfälle des 10. Jahrhunderts in Kempten, Stadt Bingen am Rhein Bei Ausgrabungen, die Laien kurz vor der Mitte des 19. Jahrhunderts in einem alten Gräberfeld am Nordostrand des Rochusberges zu Kempten, Stadt Bingen am Rhein, durchgeführt haben, kamen zwei rautenförmige Schaftdornpfeilspitzen altungarischen Typs aus dem 10. Jahrhundert zutage. Sie stammen offenbar aus dem Grab eines von ungarischen Bogenschützen erschossenen Frankenkriegers, das die kleine Gesamtzahl derzeit bekannter Gräber von Opfern der Ungarneinfälle in das Ostfrankenreich (899-955) um ein weiteres erhöht. Das Grab in Kempten und der Sarkophag von Herzog Konrad dem Roten in Worms, der in der Schlacht auf dem Lechfeld bei Augsburg (955) vom Pfeil eines Ungarn getötet worden war, sind die ersten archäologischen Spuren der Ungarneinfälle, die bisher auf dem Westufer des Rheins entdeckt werden konnten.

description: Fossil Brachiopod from a Roman Period Grave at Weklice, Site 7 (Woj. Warmińsko-Mazurskie / PL). On Past Uses of Fossils The cemetery of the Wielbark Culture at Weklice is located in northern Poland in the Vistula delta on the Elbląg Heights. It was used during the Roman period (1st-4th century) by a multi-ethnic community, identified on the basis of written sources as Goths and Gepids. Analysis of archaeological finds indicates that the local community had numerous supraregional contacts with many regions of Europe, including the Roman Empire, the Black Sea and Scandinavia. This article presents a find comprising an object discovered in an inhumation grave, originally taken to be a mineralised peach stone (Prunus persica L. Batsch). When re-examined, the find has been unequivocally demonstrated to be a fossil brachiopod. Based on external morphology, the specimen most likely belongs to the short-looped Terebratulida. Given the new identification, we discuss how fossils were used and perceived in the past. The brachiopod from Weklice was used as a pendant or was placed in the grave pit inside a wooden box. The item may have been used as an amulet, a medicinal object or a gaming token. The interpretation of this unique find from Weklice is discussed in the context of other discoveries of fossil plant and animal remains in Roman period graves from areas around the Baltic Sea.

description: En tant qu’enseignantes spécialisées intervenant dans l’école ordinaire vaudoise pour accompagner des élèves ayant des besoins spécifiques, nous sommes parfois confrontées à des difficultés de collaboration avec certains enseignants généralistes. Ce mémoire est une tentative de compréhension des éléments et des processus qui peuvent entrer en jeu et complexifier cette relation professionnelle. Il a été conçu dans une démarche clinique qui s’appuie sur l’analyse de nos récits de terrain. Nous avons commencé par des considérations historiques et avons constaté qu’elles jouent un rôle important dans la construction des identités professionnelles et des représentations de chacun. Nous avons par exemple identifié la présence d’un désir d’uniformisation chez les enseignants généralistes de nos situations qui se heurte à la réalité actuelle du terrain. En effet, l’école vaudoise s’efforce de cheminer vers l’inclusion avec tous les changements que cela implique. Face à ce bouleversement, des résistances peuvent se manifester en chacun de nous par la mise en place de stratégies de défense, comme le fait de se déresponsabiliser ou de se replier sur ses croyances. A partir de cette réflexion, nous nous sommes penchées sur le rapport à l’altérité. Nous avons constaté que face à la différence de l’autre, chaque personne réagit à sa manière. Dans les situations de notre étude, il est ressorti que les stratégies utilisées ont comme conséquences de refermer les personnes sur elles-mêmes et de diminuer l’échange verbal. Nous sommes ensuite allées à la rencontre de ce que cela provoque dans l’intériorité des personnes concernées. Nous avons mis en évidence le fait que derrière l’indignation et la colère, il y a une souffrance vécue chez nous et parfois aussi chez les enseignants généralistes de nos récits. Dans un métier de l’humain comme le nôtre, il nous parait important d’être à l’écoute de notre intériorité. En effet, c’est notamment grâce à elle que nous sommes capables de nous mettre en résonnance avec les autres pour les comprendre ; mais c’est aussi en elle que, lorsque l’éthique professionnelle est en jeu, nous pouvons trouver la force pour nous mobiliser et agir de façon professionnelle.

Słupsk, woj. pomorskie / PL) geborgen wurde. Der überregionale Charakter der Grabausstattung, zu der eine Stützarmfibel mit Durchlochung zur Befestigung eines Bügelrings und ferner zwei Vogelkopfnadeln gehören, ist bemerkenswert und zeugt von weiträumigen, in verschiedene Richtungen weisenden Kontakten der Bestattungsgemeinschaft. Die Fibel gehört zu den Stützarmfibeln mit stabförmigem Bügel, schmalem Fuß und mittlerem Achsenträger, die hauptsächlich im breit verstandenen Raum beiderseits des unteren Rheins getragen wurden. Zugleich gehört sie zu einer kleinen Gruppe von Exemplaren, für die hier die Bezeichnung »Variante Rhenen« vorgeschlagen wird. Solche Stücke zeichnen sich durch eine Bügelkopfdurchlochung aus, in der zumeist noch ein Splint mit einhängendem Ring sitzt. Die beiden Nadeln des Grabes gehören in einen südskandinavischen Kontext. Der Komplex unterstreicht einmal mehr die sich immer deutlicher abzeichnenden engen Beziehungen der in der frühen Völkerwanderungszeit im Raum zwischen Oder und Weichsel ansässigen Bevölkerungsgruppen zu anderen, mitunter weit entfernten Regionen West-, Mittel- und Nordeuropas.

description: The new capabilities that JWST offers in the near- and mid-infrared (IR) are used to investigate in unprecedented detail the nature of optical/near-IR faint, mid-IR bright sources, HST-dark galaxies among them. We gather JWST data from the CEERS survey in the EGS, jointly with HST data, and analyze spatially resolved optical-to-mid-IR spectral energy distributions (SEDs) to estimate both photometric redshifts in 2 dimensions and stellar populations properties in a pixel-by-pixel basis. We select 138 galaxies with F150W-F356W>1.5 mag, F356W<27.5 mag. The nature of these sources is threefold: (1) 71% are dusty star-forming galaxies at 2100 Gyr^-1); (2) 18% are quiescent/dormant (i.e., subject to reignition and rejuvenation) galaxies at 3

description: We develop a fast algorithm for Kalman Filter applied to the random walk forecast model. The key idea is an efficient representation of the estimate covariance matrix at each time-step as a weighted sum of two contributions - the process noise covariance matrix and a low rank term computed from a generalized eigenvalue problem, which combines information from the noise covariance matrix and the data. We describe an efficient algorithm to update the weights of the above terms and the computation of eigenmodes of the generalized eigenvalue problem (GEP). The resulting algorithm for the Kalman filter with a random walk forecast model scales as $\bigO(N)$ in memory and $\bigO(N \log N)$ in computational cost, where $N$ is the number of grid points. We show how to efficiently compute measures of uncertainty and conditional realizations from the state distribution at each time step. An extension to the case with nonlinear measurement operators is also discussed. Numerical experiments demonstrate the performance of our algorithms, which are applied to a synthetic example from monitoring CO$_2$ in the subsurface using travel time tomography.

description: Modification of calcium carbonate particles with surfactant significantly improves the properties of the calcium carbonate coating on paper. In this study, unmodified and CTAB (hexadecyltetramethylammonium bromide)- and oleate-modified calcium carbonate nanoparticles were prepared using the wet carbonation technique for paper coating. CTAB (cationic surfactant) and sodium oleate (anionic surfactant) were used to modify the size, morphology, and surface properties of the precipitated nanoparticles. The obtained particles were characterized using X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, zeta potential measurements, thermal gravimetric analysis (TGA), and transmission electron microscopy (TEM). Coating colors were formulated from the prepared unmodified and modified calcium carbonates and examined by creating a thin coating layer on reference paper. The effect of calcium carbonate particle size and surface modification on paper properties, such as coating thickness, coating weight, surface roughness, air permeability, brightness, whiteness, opacity, and hydrophobicity, were investigated and compared with commercial ground (GCC) calcium carbonate-coated papers. The results show that the obtained calcium carbonate nanoparticles are in the calcite phase. The morphology of the prepared calcium carbonate nanoparticles is rhombohedral, and the average particle diameter is less than 100 nm. Compared to commercial GCC, the use of unmodified and CTAB- and oleate-modified calcium carbonate nanoparticles in paper coating improves the properties of paper. The highest measured paper properties were observed for paper coated with oleate-modifed nanoparticles, where an increase in smoothness (decrease in paper roughness) (+23 %), brightness (+1.3 %), whiteness (+2.8 %), and opacity (+2.3 %) and a decrease in air permeability (-26 %) was obtained with 25% less coat weight. The water contact angle at a drop age time of 10 min was about 112° for the paper coated with oleate-modified nanoparticles and 42° for paper coated with CTAB-modified nanoparticles compared to 104° for GCC-coated paper.

description: The 1H-NMR spectra of some 1,3-diacetamino-1,3-diphenylpropanes and of the dichloro-Pt(II) complexes of the corresponding diamines are compared with their simulated spectra leading to the stereochemical assignments meso I rac and erythro!threo, respectively.- IR-spectra data of our "diaqua/sulfato complexes" indicate coordinated as well as free (counterionic) sulfate. Die 1H-NMR-Spektren einiger 1,3-Diphenylpropan-1,3-diamine und ihrer Dichlor-Pt(II)-Komplexe wurden mit den berechneten Spektren verglichen und führten so zu den stereochemischen Zuordnungen meso I rac bzw. erythro!threo.- Die IR-spektroskopischen Daten unserer "diäqua/sulfato Komplexe" weisen auf koordiniertes und freies (gegenionisches) Sulfat in diesen Verbindungen hin.

description: The title diamines were prepared according to von Auwer's/Arakawa's procedures starting from appropriately substituted benzaldehydes and acetophenones via chalcones, addition of two moles of hydroxylamine, reduction, and separation of diastereomers as N,N'-bisacetamides. - The Pt(II) complexes of the title ligands are described in the following paper. Die Titel-Diamine werden nach von Auwers bzw. Arakawa aus entspr. substituierten Benzaldehyden und Acetophenonen über die Chalcone hergestellt, an die 2 Mol Hydroxylamin addiert werden. Reduktion und Trennung der Diastereomeren auf der Stufe der Bisacetamide führen zu den Diaminen, die als Liganden für Pt(II) Komplexe dienen (s. nachstehende Arbeit).

description: Die Münze im Lampenspiegel. Zu Vorkommen und Bedeutung des Phänomens bei römischen Grab- und Weihefunden Der vorliegende Aufsatz geht der Frage der Deutung von Grab- und Weihefunden römischer Lampen nach, in deren Spiegel Münzen deponiert wurden. Der Verfasser sammelt Hinweise darauf, dass die Münze im Lampenspiegel, die das Einfüllloch für das Öl mehr oder weniger verdeckt, als Symbol für den Tod verstanden wurde. Insofern eigneten sich Lampen mit Münzen im Spiegel gleichermaßen als Grabbeigaben wie als Weihegaben für Götter der Unterwelt. Nach Ansicht des Verfassers dürfte so ein Fund aus Sarmizegetusa ein Opfer für die Göttin Domna und einer aus Vindonissa ein Opfer für Hekate gewesen sein.

description: The crystal structure of (—)-corycavinium (+)-10-camphorsulfonate has been investigated by X-ray analysis. The structure of (-)-corycavinium ion ( = (-)-(7S,13S,14R)-5,6,13,13a-tetrahydro-l3a-hydroxy-7-methyl- 2,3;9,10-bis(methylenedioxy)-8H-dibenzo[a,g]quinolizinium), has been determined. The conformation with B/Ccis -conjunction, a twisted half-chair of ring B, and a half-chair of ring C, as well as a -oriented substituted groups N - M e , C - Me, and C - O H is revealed. Feeding experiments with cell suspension cultures of Corydalis incisa (Papaveraceae) defined the intermediacy of (—)-corycavinium in the route from protoberberine-type to hexahydrobenzo[ c]phenanthridine-type of alkaloids. On the basis of the present crystal conformation, the stereospecificity of the relating enzyme is biogenetically considered.

The nature of Damped Lyman-α and MgII absorbers explored with their dust contents

description: We estimate the abundance of dust in damped Lyman-α absorbers (DLAs) by statistically measuring the excess reddening they induce on their background quasars. We detect systematic reddening behind DLA consistent with the SMC type reddening curve, but it is inconsistent with the Milky Way type reddening. We find that the derived dust-to-gas ratio is, on average, inversely proportional to the column density of neutral hydrogen, implying that the amount of dust is constant, irrespective of the column density of hydrogen. It means that the average metallicity is inversely proportional to the column density of hydrogen, unless the average dust-to-metal ratio varies with the hydrogen column density. This indicates that the prime origin of metals seen in DLAs is not by in situ star formation, with which Z ~ N_{HI}^{0.4} is expected from the empirical star formation law, contrary to our observation. We interpret the metals observed in absorbers being deposited dominantly from nearby galaxies by galactic winds ubiquitous in intergalactic space. When extrapolating the relation between dust-to-gas ratio and HI column density to lower column density, we find a value which is consistent with what is observed for Mg II absorbers.

description: Das Vorwort zum Sammelband, der das Ergebnis der internationalen wissenschaftlichen Konferenz "Sowjetmacht und Medien" ist. Die Konferenz fand vom 1. bis 3. Oktober 2003 im Rahmen des Forschungsprojekts "Das Politische als Kommunikationsraum in der Geschichte" an der Universität Bielefeld statt. Die Tagung untersuchte die Transformation des Begriffs des Politischen unter den Bedingungen der Einführung neuer technischer Massenmedien (Fotografie, Kino und Radio) in der Sowjetunion, die unterschiedliche, ja widersprüchliche Funktionen erfüllen konnten: Einerseits dienten sie dem utopischen Projekt der Avantgarde, das durch eine Auflösung des Privaten in der übergreifenden Politisierung der Gesellschaft gekennzeichnet war, andererseits trugen sie zur gegenläufigen Tendenz der Familisierung des Politischen in der Mythologie der Massenkultur unter Stalin bei. Die stalinistische Ära war also durch ein Spannungsverhältnis zwischen der "Archaisierung" der Kultur und dem Streben nach Modernisierung gekennzeichnet, das sich gerade in der verstärkten Nutzung neuer technischer Medien ausdrückte, die in ein komplexes Wechselverhältnis zu älteren Medien (Literatur, Malerei, Musik, Theater, Folklore usw.) traten. Das Buch will zu einer vergleichenden Analyse der Medien in der Sowjetunion der 1920er und 30er Jahre anregen. Von besonderem Interesse ist dabei die Diskussion der Dominanzen, Interaktionen und Konkurrenzen innerhalb des Mediensystems, der Übersetzbarkeit bzw. Unübersetzbarkeit sowie der Kombinationsmöglichkeiten und Beziehungen zwischen den einzelnen Medien.

description: Pyrrolidin-2-yl-groups located at C-4 of 3,4-dihydro- or 1,2,3,4-tetrahydroisoquinolines, respectively, are lost in the course of dehydrogenation of these isoquinoline derivatives. However, acyclically substituted isoquinolines, hydrogenated in ring B, 2-benzyl-4-(l-dimethylaminoethyl)-l,2,3,4- tetrahydroisoquinoline, e.g., show loss of the amine group only by benzylic cleavage, affording 4-ethylisoquinoline. Scope and limitation of this reaction are determined using specifically substituted isoquinolines. C-4-Pyrrolidin-2-yl-3,4-dihydro- oder 1,2,3,4-tetrahydroisochinoline verlieren bei der Pd-katalysierten Dehydrierung diese Substituenten, während offenkettig substituierte ringhydrierte Isochinoline, z.B. 2-Benzyl-4-(ldimethylaminoethyl)- l,2,3,4-tetrahydroisochinolin nur die Aminfunktion unter Benzylspaltung zu 4-Ethylisochinolin abspalten. Die Grenzen dieser Reaktion werden anhand der Dehydrierung speziell substituierter Isochinolin- Derivate abgesteckt.
Invisible Early La Tène Elites in Moravia?

description: The Invisible Early La Tène Elites in Moravia? Evidence from a Bronze Flagon Mount Found at Pavlov-Děvín (Okr. Břeclav / CZ) Until recently, the Early La Tène period in Moravia lay at the margins of research interest of this period in Europe. Most probably, this was due to the lack of attractive discoveries, such as graves furnished with prestige goods (gold objects, Early Style decoration, Mediterranean imports). The aim of the article is to evaluate the bronze figure from the beaked flagon found at Pavlov-Děvín (okr. Břeclav / CZ) in a broader context and to make an overview of finds testifying to the presence of local élites in 5th-century BC Moravia. The best parallels for the Pavlov-Děvín figure can be found among bronze flagon fittings produced in the Transalpine area mainly in the second half of the 5th century BC and inspired by imported Etruscan models. The owner of the flagon part found in the Pavlov Hills was most probably one of the Early La Tène period élite, comparable with those buried in the »princely« graves of Dürrnberg and the Glauberg. Apparently, such local élites were perfectly capable of providing themselves with prestigious products of specialist metal-working workshops, even though subsequently such objects were not buried in graves.

description: We investigate the question which Q-valued characters and characters of Q-representations of finite groups are Z-linear combinations of permutation characters. This question is known to reduce to that for quasi-elementary groups, and we give a solution in that case. As one of the applications, we exhibit a family of simple groups with rational representations whose smallest multiple that is a permutation representation can be arbitrarily large.

description: A House on a Holy Mountain? A Late Bronze Age Building on Mount Radunia in the Ślęża Massif (Woj. Dolnośląskie / PL) The Ślęża Massif, a vast nature reserve and a complex of archaeological sites, has for many years been considered to be a place of religious practices. However, the latest research has shed a completely new light on this issue. As a matter of fact, this mountainous area played not only a cult role, but most of all it served as a place of refuge and exploitation of natural resources from prehistoric times up to the modern era. The aim of this paper is to present the results of the excavation on Mount Radunia, located on the southern side of the massif, and the discovery of remains of a building found next to Kacza Kałuża, a natural water reservoir and the centre of this archaeological site. The building was erected as a semi-subterranean construction with a free-standing wooden superstructure in the form of a gabled roof. Furthermore, the exploration of the building yielded a large amount of artefacts, which revealed the Late Bronze Age date of the construction and the utilitarian character of the site of Radunia.
