Eine Analyse von vier Lehrwerken für Deutsch- und Schwedischunterricht

2015

Tämän tutkielman tarkoituksena on selvittää, kuinka autenttisuus näyttäytyy yläkoulun saksan ja ruotsin oppikirjoissa. Tutkimuksen taustalla on saksan ja ruotsin heikentynyt asema koulukielinä: saksan lukijamäärät ovat laskussa ja ruotsin kielen asemasta pakollisena kielenä keskustellaan jatkuvasti. Yhtenä ratkaisuna ongelmaan on ehdotettu oppilaita innostavia ja motivoivia, autenttisia oppimateriaaleja ja menetelmiä. Autenttisuus kieltenopetuksessa on monimuotoinen ilmiö, jonka toteuttaminen käytännössä on monen opettajan mielestä haastavaa ja aikaavievää. Suurin osa suomalaisista kieltenopettajista turvautuukin työssään oppikirjoihin, joten halusin selvittää, missä määrin autenttisuus huo…

Global linear feedback control for the generalized Lorenz system

2006

Abstract In this paper we show how the chaotic behavior of the Chen system can be controlled via feedback technique. We design both a nonlinear feedback controller and a linear one which globally regulate the closed-loop system states to a given point. We finally show that our approach works also for the whole family of the generalized Lorenz system.

Representatives of the Magnoliaceae juss. family growing upon different climatic conditions from the botanical gardens collections of Taras Shevchenk…

2016

Has been described the phenology of deciduous magnolias growing ex situ in botanical gardens of Acad. O.V Fomin SRC "Institute of Biology" National Taras Shevchenko University of Kyiv and the University and Latvia (Riga). 9 species, 1 variety and 3 hybrids identical for both collections of botanical gardens were selected and used for phenological observations. The studied plants were resistant to winter and summer climatic factors, were marked the parameters that determine their plasticity in less precipitation in Ukraine and Latvia, as compared to the places of their natural habitat, and expanding the use of exotic species in landscaping design of the megapolises.

The taxonomic position of Roesleria subterranea

2006

The genus Roesleria was introduced with the single species Roesleria hypogaea (current name: R. subterranea) by Thümen in 1877. The species was originally described from roots of grapevine and recognised as a facultative root-rotting parasite. The mazaediate ascoma with evanescent asci led to the assumption that Roesleria would be an ally of mazaediate lichens. In this study we calculate 28S, 18S as well ITS1-5.8S-ITS2 rDNA phylogenies. These data indicate that Roesleria is closely related to Hymenoscyphus (Helotiales). In contrast to other members of the Helotiales, the ascospores of Roesleria are passively released, and a distinct apical apparatus cannot be observed by LM. Electron optic …

Distribution ofLeprariain Latvia in Relation to Tree Substratum and Deciduous Forest Type

2012

The aim of the study was to evaluate the distribution of Lepraria lichen species in dry deciduous forests, in relation to tree substratum and forest characteristics. In total, 34 localities with 1020 trees (13 tree species) were studied in different parts of Latvia. Lepraria spp. were found on 642 trees: L. eburnea on 8 trees, L. incana on 80 trees, and L. lobificans on 568 trees. Lepraria eburnea was recorded for the first time in Latvia. Tree species, tree bark crevice depth, inclination, pH and forest type were the most important variables explaining the presence of Lepraria species. Lepraria incana was associated with Quercus robur and Tilia cordata, while L. lobificans was associated w…

Pityriasis lichenoides chronica associated with herpes simplex virus type 2.

2012

Introduction. Pityriasis lichenoides is a rare, acquired spectrum of skin conditions of an unknown etiology.Case Report. A 28-year-old man presented with recurrent outbreaks of herpes simplex virus associated with the onset of red-to-brown maculopapules located predominantly in trunk in each recurrence. Positive serologies to herpes simplex virus type 2 were detected. Histopathological examination of one of the lesions was consistent with a diagnosis of pityriasis lichenoides chronica.Discussion. Pityriasis lichenoides is a rare cutaneous entity of an unknown cause which includes different clinical presentations. A number of infectious agents have been implicated based on the clustering of …
