Potop, V. ; Mateescu, C.D. ; Türkott, L. ; Zahradníček, Pavel ; Boroneant, C. ; Constantinescu, F. ; Iamandei, M.
This study presents applications of DSSAT version 4.5 software package to simulate thermophilic crops. The results are used to identified adaptation options to reduce impacts of climate changes, pest and diseases in thermophilic crops in the central and southeastern Europe, specifically in Elbe River lowland and Romania. For the Czech Republic, experimental research at farm level includes: (1) testing thermophilic assortment of vegetables in Elbe lowland conditions; (2) monitoring the meteorological data, phenological phases, soil characteristics, leaf area and the amount of aboveground biomass on farmer vegetable fields. For Romania, the focus is put on crop water use efficiency under current and future climate scenarios for thermophilic species (maize) in different agricultural sites from south and south-eastern regions. CERES Maize and CROPGRO-vegetables modules embedded in DSSAT were used.

Foxtail Millet (Setaria italica L. BEAUV.) suitable crop to the transformative climate in the Czech Republic
Hermuth, Jiří ; Janovská, Dagmar ; Prohasková, Anna
The global climate changes bring a lot of undesirable impacts which will influence the agricultural production in the Czech Republic in the future. Nowadays the drought risks and their impact on the agricultural production have begun to show up very strongly. One of the main solutions might be the breeding and selection of more resistant species or/and varieties which are more adaptable to lesser water availability and which are more resistant to the new climate. This paper would like to present the foxtail millet as a cereal which might be a valuable alternative for grain production as well as for biomass production in less favourable arid areas of our country.

Comparison of synthetic jet actuators based on sharp-edged and round-edged nozzles
Kordík, Jozef ; Trávníček, Zdeněk
Axisymmetric synthetic jet actuators based on a loudspeaker and on two types of flanged nozzles were tested and compared experimentally. The first type of the nozzle was a sharp-edged circular hole. The second one had a special design with fillets at inner and outer nozzle exit and with a small step in the middle of the nozzle. The function of the step was to prevent the flow reattachment during the extrusion stroke. The actuators with the two types of nozzles were operated at resonance and were compared first qualitatively using a simple phase locked flow visualization. Then the hot-wire anemometer was used to measure velocity \ndistributions along nozzle axis and velocity profiles at the nozzle exit. Comparison of the nozzles was based on evaluation of the characteristic velocity and integral quantities (volumetric, momentum, and kinetic energy fluxes). It was found out that these quantities, which were evaluated at the nozzle exit, differ substantially for both nozzles. On the other hand the velocity flow field in farther distances from the nozzle exit area did not exhibit such prominent differences.

Water quality change in small watersheds after sewage water treatment plant building
Rödlová, Sylva ; Langhammer, Jakub (advisor) ; Kvítek, Tomáš (referee) ; Pechar, Libor (referee)
Změny kvality vody v malých tocích, vyvolané vybudováním čistírny odpadních vod, představují doposud málo studované a přitom velmi aktuální téma současné hydrologie. Tato studie se zabývá popsáním těchto změn a faktorů, které je ovlivňují. Pro účely výzkumu bylo vybráno pět malých, zemědělsky využívaných povodí prvního řádu (čtyři povodí průměrně 6 km2 , jedno 16 km2 ). V každém zájmovém území byla vždy jedna vesnice od 640 do 2 500 obyvatel. Během 7 - 16 let trvajícího měsíčního monitoringu základních indikátorů kvality vody (O2, BSK5, CHSKCr, TOC, konduktivita, N-NH4, N-NO2, N-NO3, PC, P-PO4) byla zachycena stavba čistíren v obcích. Spolu s daty o účinnosti čistíren byly vyhodnoceny změny kvality vody v toku. Identifikované typy změn ukazují na problematické aspekty vývoje kvality vody v malých povodích. Kromě očekávaného rychlého a razantního snížení hodnot zátěže po výstavbě čistírny odpadních vod se vyskytují i odlišné projevy změn - pouze mírné snížení zátěže, stagnace, dokonce i zvýšení koncentrací sledovaných indikátorů. Mezi další typické změny patří navýšení hodnot 1-2 roky před uvedením čistírny do provozu a opožděná nitrifikace v toku způsobená nevhodným provozem čistírny. Mezi nejdůležitější faktory ovlivňující změny patří provoz čistírny, velikost průtoku recipientu, zemědělské...

Assesment of air concentration in water depending on pressure
Uttendorfský, Petr ; Himr, Daniel (referee) ; Pochylý, František (advisor)
This bachelor thesis deals with air concentration in the water. The general conception comes from Henry's law about gas dissolved in the liquids depending on pressure. The basic derivation, the values which influence dissolvability and the Henry's Law constant´s forms are discussed here. Next part is about the usage aeration in the industry and in the construction of aeration systems. The special equipment is for realization experiment. This special equipment is gas´s accumulator based. The measured values are expressed as the tables and the graphs. The data from experiment validated the force of Henry´s Law: with growing pressure above water level, the air concentration in the water is growing too.

Changes of extracellular and intracellular water distribution after weight reduction in premenopausal women.
Prášková, Lenka ; Bunc, Václav (advisor) ; Malá, Lucia (referee)
,lb.\trakt Abstrakt Název: Změny v distribuci extracelulární a intracelulární vody po redukci hmotnosti premenopauzálnich žen. Changes oj extracellular and intracellular water distribution ajter weight reduction in premenopausal women. Cíle práce: Protože tělesné tekutiny tvoří více než polovinu tělesné hmotnosti, je třeba při redukci hmotnosti kontrolovat jejich stav. Úkolem práce je hodnocení objemu a distribuce tělesné vody u dospěl)·ch premenopauzálních žen s nadváhou a 1. stupněm obezity a detekce jejich změn po redukci hmotnosti. Práce se zároveň snaží poukázat na možné faktory působící na objem a distribuci tělesných tekutin u žen. Metoda: Výzkumný soubor tvořilo 25 premenopauzálních žen, u kterých byl ve srovnávací studii bez kontrolní skupiny charakterizován objem a distribuce tělesné vody před a po dokončení IO t)·denního redukčního programu. Vybrané parametry tělesného složení byly hodnoceny multifrekvenční bioimpedanční metodou, která je primárně určena pro měření objemů tělesných tekutin. Výsledky: Ve sledovaném souboru byl při vstupním vyšetření u většiny žen prokázán relativní nedostatek celkové tělesné vody, ale poměr extracelulární a intracelulární tekutiny v organismu byl zvýšený, což svědčí pro poruchu distribuce vody ve prospěch extracelulárního prostoru u žen s nadváhou a 1. stupněm...

How Tax, Labor Market and Product Markets Reforms Influence Foreign Direct Investment
Tydlačková, Stanislava ; Vacek, Pavel (advisor) ; Serdarevič, Goran (referee)
This work analyses industry level Foreign Direct Investment (FDI) inflows in order to find out if their determinants are the same for all industries or if they differ and how. The second important question is if various qualitative variables as labour market or product market liberalization or taxation determines flows to individual industries. I analyse seven industries by System GMM model for period from 1994 till 2009. The results suggests that inflows to each industry are driven by distinct set of determinants. While there are nearly non-significant determinants for agriculture among explanatory variables I used, there is many of them significant for services. Concerning qualitative variables, labour market liberalization influence FDI inflows to manufacturing and mining, product market liberalization influence inflows to transportation and electricity, gas and water industry. The level of taxation seem to be significant determinant of FDI inflows to manufacturing. Keywords FDI, Foreign direct investment by industry, Structural reforms, Labour Market, Lib- eralization, GMM, taxation 4
