The University of Tartu is a classical university in the city of Tartu, Estonia. University of Tartu is the national university of Estonia; it is the biggest and highest-ranked university in Estonia. The University of Tartu is a member of the Coimbra Group and the Utrecht Network, and was established by King Gustavus Adolphus of Sweden in 1632, thus being one of the oldest universities in Northern Europe.

A review of scientific literature, geological maps and available previous digital data on ice-marginal positions, glacial landforms and sediment distribution are utilised to reconstruct ice streams and lobes, and the maximum (LGM) and subsequent recessional ice-marginal positions of the Scandinavian Ice Sheet (SIS) southeast of the Baltic Sea. This paper presents preliminary results of the ongoing research that aims to build a Geographic Information System (GIS) based model on the extent and timing of the last SIS in the area between its maximum extent and the Baltic Sea. Digitized subglacial bedforms, ice marginal and other glacial landforms and features from published sources are compared and validated against digital elevation model (DEM). This has allowed specifying, revising and questioning the location of the LGM, and to interpret and correlate the post-LGM ice streams with marginal positions. Morphological evidence demonstrates that large ice streams of between 100 and 300. km lengths, were in operation ca 2-3. ka after the LGM and formed the Middle and North Lithuanian end moraines. Ice streams from the Onega and White Sea basins had high lateral slopes and clearly channelled flow while the ice streams that drained the ice sheet through the Ladoga-Ilmen depression and in the eastern Baltic usually had a fan-shaped flow pattern and morphologically unclear lateral slopes. In elevated areas and highlands that are located between ice streams a crossing of lineated bedforms is common. One set of the crossing lineations on Zemaitia, Eastern Kursa, Vidzeme, Haanja, Latgale and Sudoma highlands that are 200-350. km inside of the LGM margin, has northwest-southeast orientation that in general conforms to the direction of ice flow during the LGM and Baltija phases. It is expected that the presented compilation will stimulate discussions and scrutiny of earlier published data and generate ideas for future investigations. © 2010 Elsevier Ltd. Source

Method of preparation of surface coating of variable transmittance and an electro-optical layered appliance including the same comprises dispersing of liquid crystal microdroplets in hydrolyzable and polymerizable precursors and applying obtained mixture on a surface by spraying. Applying the material to the surface by spraying is intrinsically related to the synthesis processes because the properties of the surrounding environment (i.e. content of water and acidity, UV radiation) and the chemical reactions that take place during spraying have considerable influence on the properties (i.e. driving voltage, thickness of obtained layer). Obtained layered appliance comprises of a matrix material with dispersed microdroplets of liquid crystal obtained by the described method, electrically conductive transparent electrodes with contacts, a dielectric material, substrate and covering layers.

Viral vectors are potential tools for eliminating the viability of eukaryotic cells in anti-cancer therapies since they can efficiently destroy the cancer cells and trigger an immune response against tumours. Typically viruses are not specific to cancer cells and all methods known in art aiming to the construction of cancer-specific viruses suffer from serious problems. The present invention presents a universal method to overcome these problems and is usable for any DNA virus replicating in nucleus or for any layered vector of RNA viruses. In this method the viral gene expression and/or replication will be blocked by the introduction of one or more aberrantly spliced introns into crucial gene expression units of the virus or vector. Lethal effect of these mutations is reverted in a controlled manner by the delivery of splice-switch oligonucleotide (s) correcting the introduced defects and restoring the biological functionality of the virus or vector, including cytolytic properties.
