No full textArmament and Society in the Mirror of the Avar Archaelogy The Transdanubia-Phenomenon Revisited
No full textOne of the most significant problems of the A var archaeology is the question of
Germanic (mainly Gepidic) continuity in Transdanubia. In my paper I would like to
make some comments on the so-called Transdanubia-phenomenon of the Early A var
Carpathian Basin based on the analysis of weapon-combinations found in six
cemeteries of Eastern Transdanubia. I intend to answer the following questions: I.
How far the weapon-combinations of the East-Transdanubian cemeteries of the early
Avar Period (568-650) are identical or similar to the general picture of Avar armament
drawn by contemporary cemeteries? 2. Are the weapon-combinations or armament of
these cemeteries similar to that of the earlier Gepidic and Langobardic sites from the
early 6th centuries or to the contemporary Germanic (Alemannic, Frank or Bavarian)
cemeteries of the present-day Germany?
As a result, the early A var cemeteries of Transdanubia are characterized by the
relatively high number of close-combat weapons compared to other sites of the Avar
Khaganate. However, comparing to Merovingian sites the burials containing only
close-combat weapons are very low and in most of the cases the weapon-combinations
characteristic to this culture is missing
Ecophysiological characterization of Citrus sinensis (L.) Osbeck and relationships with type and amount of biogenic emissions
No full textIn this paper are shown the results obtained on Citrus sinensis (L.) Osbeck during the sampling campaigns performed in Burriana (Spain) in the frame of B.E.M.A. project. The daily trends of photosynthesis (A) showed higher values at morning and a decrement during the hottest hours of the day; for leaf transpiration (E) we observed a slight increment during the day. During different months (May '96, June '97 and July '95) we noted a progressive reduction in gas exchange of the leaves in relation to build-up of summer stress condition (-49% and -60% for June and July respect to May). In particular, net photosynthesis and leaf transpiration measured on Citrus leaves were, in general, characterised by low average values (2.7 +/- 0.06 (s.e.) mu mol CO2 m(-2)s(-1) and 0.665 +/- 0.021 (s.e.) mmol H2O m(-2)s(-1) for current leaves, respectively). The relationship between biogenic volatile organic compound (BVOC) emission rates normalised by assimilation (A) and gas exchange parameters as E/A ratio is reported. This latter is considered as an useful functional index to determine different vegetation types on a functional basis. We also found a good correlation between BVOC normalised emissions with air temperature. This behaviour has been reported for other species having monoterpene compounds in storage structures as Pinus species. Moreover, it is evident an uncoupling between BVOC emissions and photosynthesis. (C) 1999 Elsevier Science Ltd. All rights reserved

No full text„A kerítésen azt harsogta a plakát...” Reklám és ismeretterjesztés a kaposvári Csiky Gergely Színház történetében
No full textToday, there are many different advertising forms and media available to share information, whereas in the past, theatres often promoted their production at the time on a single sheet of paper. Playbills, posters, and brochures tried to impress audiences with the title of the play and the names of the creators (author, actors, director, etc.), and then these prints became more spectacular and richer in visual elements. As Marvin Carlson pointed out, these advertisements did not only serve as invitations but also helped the audience to interpret the performance. In this paper, I study the brochures and posters of the Csiky Gergely Theatre in Kaposvár. In the 1970s, the theatre employed talented editors and versatile artists who were involved in the graphic design of the printed materials. Focusing on the visual communication of these publications, I examine the possible processes of reception, promotion, and audience education.</jats:p
Florisztikai felmérések hibaforrásai I. „Jószándékú” flórahamisítások: „kakukk” a Medvesen
No full textThe aim of the planned thematic studies is to point out the main biases and/or errors of floristic surveys in Hungary. In this first article of the series we focus on those examples when native species were planted out of their original habitats and/or range by a non-professional naturalist. The sources of information are those letters that were posted by Ferenc Varga to the first author of this article in 2005. The circumstances of the transplantation of 10 phytogeographycally significant species of the investigated area and/or the Pannonicum ( Adonis vernalis , Arum orientale , Asarum europaeum , Genista germanica , Phragmites australis , Pulsatilla grandis , P. nigricans , Salvia aethiopis , Viola alba , Xeranthemum annuum ) are detailed in the text and summarised in a table. The correspondence between the first author and Ferenc Varga provides insight how the ambition of a non-professional naturalist can influence the flora of an area. Most of the species were removed from South and transplanted to North, almost 10 km away from their original stands. With the exception of Adonis vernalis and Genista germanica at least one transplantation of the species was successful. In the case of Salvia aethiopis , the naturalized populations came 1.25 km close to Slovakia, where this species is a very rare and endangered (EN) taxon.A tervezett cikksorozat a florisztikai térképezések, illetve az így keletkezett adatbázisok hibaforrásaira szeretné felhívni a figyelmet. E dolgozatban elsőként a „jószándékú” flórahamisítás esetét mutatjuk be egy kistáj, a Medves vidék példáján. Az adatok forrását azok a 2005-ben postázott levelek képezik, amelyeket Varga Ferenc az elsőszerző kérésére fogalmazott meg. A dolgozatban 10, a tájegység és/vagy a Pannonicum szempontjából növényföldrajzilag is jelentős faj ( Adonis vernalis , Arum orientale , Asarum europaeum , Genista germanica , Phragmites australis , Pulsatilla grandis , P. nigricans , Salvia aethiopis , Viola alba , Xeranthemum annuum ) átültetésének körülményeit listázzuk. A levelezésekből kiderül, hogy amatőr botanikusként milyen módon szólhatunk bele egy terület flórájának alakulásába. A fajok döntő részét Varga Ferenc déli irányból észak felé mozdította el, átlagosan mintegy 10 km-nyire az eredeti termőhelyüktől. Az Adonis vernalis és a Genista germanica kivételével legalább egy áttelepítés sikeresen, meghonosodással végződött. A Salvia aethiopis esetében az új állomány csupán 1,25 km-nyire található Szlovákiától, ahol a faj már kifejezetten ritka, veszélyeztetett (EN) taxon
Bouché’s star of Bethlehem, Ornithogalum boucheanum (Kunth) Asch. (Hyacinthaceae), a new species in flora of Croatia
No full textPopulations of Bouché’s star of Bethlehem (Ornithogalum boucheanum (Kunth) Asch., fam. Hyacinthaceae) were recorded on Bansko Hill (Baranja, Croatia) in 2007. Since this species has not been previously confirmed in Croatia, it should be treated as a new taxon in the country and included in the Flora Croatica Database. In this paper we present a short morphological description of O. boucheanum and diagnostic morphological characters for differentiation from the related O. nutans L. We suggested O. boucheanum be evaluated as a critically endangered (CR) species of the Croatian flora, considering the small number of individuals and the small extension of its population. The recording of its populations on the edge of the loess cliff in Bansko Hill a part of which belongs to the Important Plant Area and Natura 2000, confirms the significance of this unique habitat in preserving rare and endangered plants
Prvi nalaz vrste Pomatias rivularis (Eichwald, 1829) (Mollusca: Pomatiidae) u Hrvatskoj
No full textPomatias rivularis (Eichwald, 1829) specimens were collected on Bansko Brdo (or Bansko Hill, Baranya, Croatia) during spring 2007. This species proved to be new for the Croatian fauna. Populations of Pomatias elegans (O. F. Müller, 1774) were also found on Bansko Brdo, which is the only known area in Croatia where both these two species occur. The list of 40 mollusc species (35 snails, 5 bivalves) identified in the study area is presented. Among them, Ena montana (Draparnaud, 1801) was found for the first time in the NE part of the country.Primjerci Pomatias rivularis (Eichwald, 1829) sakupljeni su tijekom proljeća 2007 na Banskom brdu (Baranja, Hrvatska). Ova je vrsta nova za faunu Hrvatske. Pronađene su i populacije vrste Pomatias elegans (O. F. Müller, 1774) također na Banskom brdu, koje je za sada jedino poznato područje u Hrvatskoj na kojem se pojavljuju obje ove vrste. U radu je priložen popis 40 vrsta mekušaca (35 vrsta puževa i 5 vrsta školjkaša) s područja Banskog brda i bliže okolice. Na ovom je popisu i Ena montana (Draparnaud, 1801), vrsta koja do sada nije bila zabilježena u sjeveroistočnom dijelu Hrvatske
Screening of 18 Mediterranean plant species for volatile organic compound emissions.
No full textEighteen tree and shrub species were screened for emissions of isoprene and other volatile organic compounds (VOCs) at three locations at Castelporziano (Italy) using a bag-enclosure sampling method followed by GC analysis. Thirty emitted compounds were identified. Temperature sensitivity of emissions of monoterpenes varied between species. Strong temperature dependencies were found for isoprene emissions. For monoterpene-emitting plant species with greatest ground cover in the dunes and macchia habitats, α-pinene, β-pinene and sabinene appeared to be the most frequently and abundantly emitted compounds. Isoprene was the major emission from the shrub species screened in the forest. Emissions from four dominant plant species were scaled up to estimate total fluxes from the dunes and macchia over a daytime period. Species with greatest biomass but low emission rates made a substantial contribution to total emission
The Zugló Circle. An informal group of abstract artists in Hungary between 1958 and 1968 Antecedents, activity and resonance (1945-1990)
No full textCette étude aborde l’activité d’un cercle artistique hongrois d’avant-garde nommé Cercle de Zugló, composé de jeunes peintres et sculpteurs abstraits. Cette formation informelle et autodidacte regroupait les artistes Imre Bak, Tibor Csiky, Sándor Csutoros, Pál Deim, János Fajó, Tamás Hencze, Endre Hortobágyi, Sándor Molnár et István Nádler, et exista de 1958 à 1968, durant la période communiste en Hongrie. Par l’examen de ses antécédents théoriques et stylistiques remontant à l’Ecole Européenne et au Groupe des artistes abstraits (1945-1948), jusqu’à sa résonance dans le retour à peinture des années quatre-vingt nommé Nouvelle Sensibilité (1978-1990), l’auteur tente de déterminer l’importance et la valeur éthique de la production abstraite du Cercle de Zugló dans le paysage artistique hongrois, isolé des actualités internationales et dominé par l’idéologie politique culturelle du réalisme socialiste.La mise en perspective théorique et stylistique permet d’une part de définir à quel point la démarche des jeunes artistes se veut être l’héritière intellectuelle et artistique de la génération plus âgée de l’avant-garde hongroise, d’orientation constructiviste. D’autre part, elle s’efforce de mettre en lumière à quel point le Cercle de Zugló se différencie de ses pères spirituels, par l’introduction et l’adoption de l’abstraction lyrique française, puis de la nouvelle abstraction géométrique américaine. Elle traduit également la volonté de redéfinir une identité artistique hongroise et de la réinsérer dans le contexte et le flux internationaux.This study examines the activity of a Hungarian avant-garde artistic circle named Zugló Circle, formed by young abstract painters and sculptors. Working in a self-taught way, this informal group gathered the artists Imre Bak, Tibor Csiky, Sándor Csutoros, Pál Deim, János Fajó, Tamás Hencze, Endre Hortobágyi, Sándor Molnár and István Nádler, and existed from 1958 to 1968, during the communist period in Hungary. Through the analysis of its theoretical and stylistic antecedents going back the European School and the Group of abstract artists (1945-1948) until its resonance in the new painterly wave of the eighties named New Sensitivity, the author determines the importance, the ethical value of the abstract production of the Zugló Circle in the Hungarian artistic landscape, which at the time was isolated and dominated by the cultural politics ideology of socialist realism.Putting the young artists’ approach in a theoretical and stylistic perspective, the author defines on one hand to which extent it wished to be the intellectual and artistic heir of the older generation of the Hungarian avant-garde, of constructivist orientation. On the other hand, this perspective also sheds light on how the Zugló Circle differentiates from its spiritual fathers, through the introduction and adoption of the French lyrical abstraction and later the American geometrical abstraction. It also reveals the will to redefine a Hungarian artistic identity and to reinsert it in an international context and stream
