Masaryk University is the second largest university in the Czech Republic, a member of the Compostela Group and the Utrecht Network. Founded in 1919 in Brno as the third Czech university , it now consists of nine faculties and 35,115 students. It is named after Tomáš Garrigue Masaryk, the first president of an independent Czechoslovakia as well as the leader of the movement for a third Czech university.In 1960 the university was renamed Jan Evangelista Purkyně University after Jan Evangelista Purkyně, a Czech biologist. In 1990, following the Velvet Revolution it regained its original name. Since 1922, over 171,000 students graduated from the university. Wikipedia.

This review summarizes basic information on the diversity of vegetation in the Czech Republic. It describes basic environmenal factors affecting vegetation, vegetation history since the last glacial, biomes occurring in the Czech Republic (zonal biomes of broad-leaved deciduous forest and forest-steppe, and azonal biomes of taiga and tundra), altitudinal zonation of vegetation and landscapes with an exceptionally high diversity of vegetation types (deep river valleys in the Bohemian Massif, karst areas, sandstone pseudokarst areas, solitary volcanic hills, glacial cirques, lowland riverine landscapes and serpentine areas). Vegetation types, delimited according to the monograph Vegetation of the Czech Republic, are described with emphasis on their diversity, ecology, history and dynamics. Source

The knowledge of the flora of the Czech Republic has substantially improved since the second version of the national Red List was published, mainly due to large-scale field recording during the last decade and the resulting large national databases. In this paper, an updated Red List is presented and compared with the previous editions of 1979 and 2000. The complete updated Red List consists of 1720 taxa (listed in Electronic Appendix 1), accounting for more then a half (59.2%) of the native flora of the Czech Republic. Of the Red-Listed taxa, 156 (9.1% of the total number on the list) are in the A categories, which include taxa that have vanished from the flora or are not known to occur at present, 471 (27.4%) are classified as critically threatened, 357 (20.8%) as threatened and 356 (20.7%) as endangered. From 1979to 2000 to2012, there has been an increase in the total number of taxa included in the Red List (from 1190to 1627 to 1720) and in most categories, mainly for the following reasons: (i) The continuing human pressure on many natural and semi-natural habitats is reflected in the increased vulnerability or level of threat to many vascular plants; some vulnerable species therefore became endangered, those endangered critically threatened, while species until recently not classified may be included in the Red List as vulnerable or even endangered. (ii) Some increase in the number of species in particular categories can be attributed to the improved knowledge of taxonomically difficult groups for which previously only incomplete species lists were available. In addition, some native species were recently discovered as new to the country's flora or described as new to science, and the status of their populations made Red-Listing necessary. (iii) Also improvements in our knowledge of the flora made the expertjudgment more precise and some species were included in the list because their long-lasting vulnerability was recognized. In contrast, 23 taxa considered extinct or missing were rediscovered. This is almost one third of the number of extinct or missing taxa in the first version of the Red List published in 1979. Source

We investigate the Gouy phase shift for full-aperture waves converging to a focal point from all directions in two and three dimensions. We find a simple interpretation for the Gouy phase in this situation and show that it has a dramatic effect on reshaping sharply localized pulses. © 2012 Optical Society of America. Source

A method for the treatment of inner surfaces of vacuum components and the device for carrying it out which enables the reduction of undesirable organic and inorganic contamination of vacuum systems not only in those that are being produced, but also enables the reduction of contamination in systems that are already in use, such as SEM, TEM, SEM-FIB, XPS, MALDI, SIMS and other analytical and inspection techniques. The proposed method for contaminant treatment derives benefit from a photocatalytic process, which is actually a chemical decomposition of contaminants using a photocatalytic material and electromagnetic radiation, the photocatalytic material being cooled simultaneously to a low temperature. The photocatalytic material is applied to the walls of the vacuum system or vacuum units, which are included in the system, in the form of a layer. If the material with photocatalytic properties is exposed to electromagnetic radiation having an appropriate wavelength, its surface is activated and a characteristic chemical reaction occurs. By using this method it is possible to decompose the contaminants so that they are finally converted to a gaseous phase, the gases being subsequently pumped out of the vacuum system. The inner surface covered with the photocatalytic layer is cooled to low temperatures, which facilitates the adsorption of the contaminants onto the surface covered with the photocatalytic layer and, consequently, increases the effectiveness of the decontamination process.
