Typologie slovenských sídelních tkání
Závracká, Andreja ; Komrska, Jan ; Moučka, Jan
Výzkumný projekt 1995 – 1996 byl zpracován s podporou RSS - Research Support Scheme, HESP - Higher Education Support Programme grant RS/HESP/1074/693/1995. Byla zpracována typologie "sídelních tkání" - t.j. středně velkých částí sídel, homogenních z hlediska hlavních kvanitatívních charakteristik - COS, CES, a výšky zástavby, definované jako průměrná výška budov VyHL (výšková hladina). Typologie byla zpracována pro soubor několika desítek tkání identifikovaných na Slovensku v průzkumech Fakulty architektury v Bratislavě a pro obdobný soubor západoevropských tkání.

Utilization of plasma spraying for production of nanocrystalline ceramic materials
Chráska, Tomáš
The technique of plasma spraying is now being investigated as an apt candidate for production of nanocrystalline materials.In the conventional plasma spraying (PS) process,powder particles injected into a high temperature plasma jet are quickly melted and propelled onto a substrate where they spread upon impact and rapidly solidify.Due to the rapid solidification, the conventional PS.

Algae and extreme environments - ecology and physiology
Elster, Josef
All photoautotrophic prokaryotes have evolved from the group Eubacteria. From fossil remains in the form of stromatolites, it has been possible to date the first prokaryotic oxyphototrophic algae (Cyanobacteria) back to almost 3,450 million years. Evolution of Eukaryotic Algae did not occur until about 700-800 million years ago. The endosymbiotic hypothesis is the most accepted theory for the origin of eukaryotic organells. Oxyphototrophic microorganisms (cyanobacteria and algae) are ubiquitous and, because of their evolutionary antiquity, are widely adapted to all the extremes related with the many changes in geological time. During the last ten years special attention has been given to study of cyanobacteria and algae in environment with extreme environment. The methodology has been steadily developing for biological-taxonomical and ecological-physiological studies.
