Recherche des valves de diatomée endemique, Cyclotella plitvicensis, a microscopes photonique et électronique

On a présenté des résultats de l’examen aux microscopes photonique et électronique de la diatomée Cyclotella plitvicensis Hust. Sauf certains caractères essentiels par lesquels l’espèce se diffère d’après Hustedt, on a réussi de constater la présence de nouveaux caractères se rapportant à l’ultrastructure des »stries« radiales et des alvéoles. Les »stries«, visibles à microscope photonique, sont en réalité (comme le montre électromicrographie, fig. 2) des rangées des alvéoles qui divergent vers la zone marginale. Dans la région du limbe entre les jets des alvéoles on trouve les orifices, invisibles par un microscope photonique (fig. 3). Sur le côté interne de la valve, entre les cavités, ils se trouvent des orifices de 6 en 10 Pm (fig. 4) qui correspondent aux organelles mentionnées pour le côté extérieur des valves

Prouzrokovači truleži korena i prizemnog dela stabla pšenice

During the 2004/05 growing season, plant deterioration was recorded at various stages of wheat crop development in the following locations: Rimski Šančevi, Kać, Kikinda, Zrenjanin, Pančevo, Kovin, Smederevo, and Smederevska Palanka. Plant samples were collected and used for pathogen identification. The results showed that the main causal organisms responsible for the outbreak of root and stem base rot in wheat were fungi of the genus Fusarium. At the Rimski Šančevi location, of the 1,308 plants of the wheat cultivar Zlatko that were subjected to analysis, 722 (55.2%) had root rot caused by fungi of the genus Fusarium, 14 (1.1%) had roots deteriorated by the fungus Gaeumannomyces graminis, while only 9 (0.7%) had symptoms typical of the causal agent of foot rot, Pseudocercosporella herpotrichoides.U proizvodnoj 2004/05. godini na više lokaliteta: Rimski Šančevi, Kać Kikinda, Zrenjanin, Pančevo, Kovin, Smederevo, Smederevska Palanka zabeleženo je propadanje biljaka u različitim fenofazama razvoja useva pšenice. Na prikupljenim uzorcima vršena je identifikacija patogena. Rezultati analize pokazali su da su glavni uzroci truleži korena i prizemnog dela stabla pšenice bile gljive iz roda Fusarium. Od 1308 analiziranih biljaka sorte Zlataka, kod 722 (55,2%) su prouzrokovač i truleži korena bile gljive iz roda Fusarium, kod 14 (1,1%) biljaka uzrok propadanja korena bila je gljiva Gaeumannomyces graminis, svega 9 (0,7%) analiziranih biljaka bilo je sa simptomima proouzrokovača sočivaste pegavosti Pseudocercosporella herpotrichoides

Revised Middle Miocene datum for initial marine fl ooding of North Croatian Basins (Pannonian Basin System, Central Paratethys)

The Pannonian Basin System (PBS) originated during the Early Miocene as a result of extensional processes between the Alpine-Carpathian and the Dinaride Orogenic Belts. The Paratethys Sea flooded the new basins successively during the Karpatian (late Burdigalian, Early Miocene) and the Early Badenian (middle Langhian, Middle Miocene). The North Croatian Basins (NCB) occupied the south-western margin of the PBS and the Central Paratethys Sea. Their initial marine flooding has until now been dated as Karpatian in age. The transgression into the NCB invaded a lacustrine environment, representing the northern prolongation of the vast Dinaride Lake System extending southwards as far as the Adriatic Plate. We reinvestigate two sections from opposite margins of the NBS – from Mt. Medvednica in the west and from Mt. Požeška in the east, including the corresponding lowermost marine Miocene deposits, in order to critically examine the Karpatian datum. Our new biostratigraphic data, integrating calcareous nannoplankton, planktic and benthic foraminifera, diatom and mollusc records, have substantially revised the previous interpretation. The presence of a calcareous nannoplankton assemblage of the NN5 Zone and the planktic and benthic foraminifera of the regional Lower Lagenidae Zone now place the transgression into the main Early Badenian transgressive pulse of Central Paratethys. Consequently, the initial marine transgression correlates accurately with the middle part of the Early Badenian, which is more than 2 m.y. younger than the previously inferred datum, and at least 1 m.y. younger than the lower boundary of the Badenian and the Middle Miocene, respectively. Finally, the basal lacustrine infill of the NCB, previously dated as Ottnangian (middle Burdigalian, Early Miocene) and continuously grading into marine deposits, has also to be reconsidered as Early Badenian

DLM Interior – design and adaptation of living space [STRAND 2023]

The spatial concept is based on fresh tones combined with neutral, natural tones to create a pleasant simulation of the natural environment in an urban environment. The interior design combines the textures of concrete, wood and turquoise marble, where the turquoise tone accentuates and visually opens the surface of the ceiling, wall decor and textiles in space. Circular and semi-circular design motifs are represented in the space, in mirror surfaces, lighting, furniture and decor. The functional organization is based on achieving free circulation. Large mirror surfaces also contribute to greater visual fluidity and a lightness of the entire space
