Hydrogen/Oxygen Fuel Cells
Vondrák, Jiří ; Sedlaříková, M. ; Černý, R. ; Klápště, Břetislav
The electrochemical low temperature fuel cells have appeared in the focus of interest recently in many institutions. e have studied the properties of various catalysts and electrolytes with the aim to do a screening of possible replacements of platinum catalysts and exchanging membranes.
Basic properties of electrochemical supercapacitors
Vondrák, Jiří ; Sedlaříková, M. ; Novák, V. ; Nečesal, P. ; Černý, R.
The fundamental properties of two kinds of supercapacitors was investigated. Two different samples were obtained. One is capacitor STAR of nominal value 7 F and the other ULTRA was nominal capacity 100 F. Linear voltammetry, self-discharge curves, and indepedance spectroscopy was used for monitoring their properties.

The paper content proposals arrangements for decrease of fertilization and fish stock in recreation Svět Fishpond.
Natural flooding in Lužnice floodplain - a holistics approach
Pithart, David ; Montagová, Martina ; Hartvich, P. ; Černý, R. ; Prach, K.
Natural flooding was analysed in the Lužnice River floodplain in a holistic approach. Benefits of natural floooding can be summarised as folows: 1.Water retention is increased due to the soil absorption, evaporation, evapotranspiration, filling of oxbows, pools and natural depressions and finally the space between the river terraces. Real flood event are analysed here in terms of water distribution among these processes. 2. Natural flooding reduces the loss of ionts from the watershed by slowing the river outflow and loss of carbon loss by slowing the decomposition processes. 3. Flooding creates and maintains floodplain geodiversity by re-forming of floodplain geomorphology and keps its biodiversity by inoculation of biota into the floodplain subsystems and differentation of its impact on these subsystems. For these reasons, maintaining and enhancing of natural flooding seems to be a prerequisite of sustainable management of riverine landscape.
Mezinárodní účetní standardy versus česká legislativa
Falková, Renata ; Králíček, Vladimír (advisor) ; Černý, Rudolf (referee)
Diplomová práce je zaměřena na aktuální problematiku vstupu Mezinárodních účetních standardů do českého právního prostředí jak z pohledu účetního tak i daňového. Po úvodu a daňové problematice následuje kapitola, která je věnována obecným rozdílům mezi IFRS a českou účetní legislativou. Mezi hlavní obecné rozdíly patří zejména Koncepční rámec, IAS 1 a IAS 8. Oblastí, která obsahuje zřejmě nejvíce odlišností a zároveň se týká téměř všech účetních jednotek je oblast dlouhodobého majetku, proto je této problematice věnována celá kapitola.
