The study “A Lullaby in a Space – the Space in the Lullaby. Miloslav Kabeláč’s Six Lullabies (1956)” is a follow-up to an earlier one (published in the previous issue). The author focuses in particular on the accompaniment structure (flute, bass clarinet, strings and small female choir), which is completely extracted from material in the solo vocal line. There is a wide range of variation, from the use of only one tone to the expansion of melodic cells from the original vocal line. The composer creates different sound textures ranging from a rhythmic pedal on a single tone to different polyphonic combinations. Sound textures trace two principal planes: one of reciprocal stratification of the sounds layers which are more or less independent and the other, where all layers are in a harmony. They exist, not in isolation from each other, but grow organically from one another.
The aim of the work is to analyze the peculiarities of Ukrainian secondary education abroad in the 1920s and 1930s on the example of the Ukrainian secondary school („Ukrainian Gymnasium“) in Czechoslovakia. The analysis of features of the organization, methodological bases of educational work of the Gymnasium in Prague as a part of the general cultural and educational activity of the Ukrainian interwar emigration is carried out.
Retroviry jsou jednoduché RNA viry, které se vyznačují schopností přepsat svou RNA do dvouřetězcové DNA a tu stabilně začlenit do genetické informace hostitelské buňky. Tato jejich vlastnost stojí za latencí viru HIV, která v současnosti představuje hlavní překážku v úspěšné léčbě HIV pozitivních pacientů. Na druhou stranu lze této jejich vlastnosti využít pro přenos genetické informace za účelem léčby četných chorob s využitím přístupů genové terapie. Pro tyto účely je však potřeba retroviry vybavit sekvencemi, které zajistí jejich stabilní aktivitu a ochrání je před umlčením., Retroviruses are simple RNA viruses, which exhibit an ability to convert their RNA to double-stranded DNA and introduce it into the host cell genome. This ability stands behind the HIV latency phenomenon - a major obstacle to successful therapy. On the other hand, this capability can be utilized for the transfer of genetic information in order to cure various diseases using gene therapy approaches. To achieve successful therapy, the retroviruses need to be equipped with sequences protecting them from silencing, thus stabilizing their activity., and Filip Šenigl.
