Vyhodnocení finanční situace podniku Metrostav a.s. na základě finanční analýzy
Vaculíková, Jana
The main aim of this batchelor labour is development of financial analysis of the company. The study is related to Metrostav Inc. in the time frame from 2004 to 2008. Theoretical part of this labour is oriented to explaining of concepts and of nature of financial analysis. There are explained financial analysis' procedures and individual methods of the company as well as what the values of indicators are about. In practical part is described the development of financial analysis in this incorporated company with the help of selected methods. The conclusion of the labour contains the whole estimation of financial situation in the company, finding of root cause of current status, if the financial situation is now better or worse that it was, and recommendation of further development from the financial control's point of view of analysed company.

Unmarked personal reference forms in academic texts
Vaculíková, Juliana-Magdalena ; Malá, Markéta (advisor) ; Brůhová, Gabriela (referee)
The present study is concerned with pronominal forms of common-gender reference in the English language. Due to the lack of an epicene third person singular pronoun in English, there is no one both grammatically and stylistically accepted method of common- gender reference. The theoretical part elaborates on various commonly used contemporary strategies, pronominal or otherwise, for example substitution of the pronoun with the definite article or repetition of the head noun. In the second part, two hundred articles published after 2009, one hundred of which was published in the United States, the other hundred having been published in either Australia or New Zealand. The articles were collected manually via the ProQuest database. The working hypothesis stated that so-called singular they would occur most frequently in Australian/New Zealand-based articles, while US authors would most often opt for generic he. Methods of generic reference were catalogued based on the choice of pronoun, internal consistency within the text, the pronoun's collocates, and journal of origin.

Effect of compression on salt weathering rate of sandstone
Vaculíková, Jana ; Bruthans, Jiří (advisor) ; Schweigstillová, Jana (referee)
The aim of this study was to investigate whether the uniaxial compression have any influence on the rate of salt decay. Tests were performed on several types of rocks, mainly sandstones from the Czech Republic and the USA. The first tests were made on Strelec sandstone blocks that were loaded with a mass of 6-24 kg, slowly saturated by solutions of NaCl, CaSO ₄. H ₂ O and KAl(SO ₄) ₂. 12 H ₂ O and dried at room temperature. Because the weathering rate was too low, another method was used for other rocks. Cubes cut fromrock were compressed by steel frame with a torque wrench to 0.75 Nm, which corresponds approximately to the uniaxial compression of 1.2 MPa. These compressed samples were tested according to a modified standard EN 12370, saturated by solution of Na2SO4 and subsequently dried in an oven. The cycle was repeated until the complete decay of the sample or until the residual weight of samples fall below 10 grams. Weight of the samples was plot over numbes of cycles. Approximately after first two cycles increase in weight due to the salt crystallization within samples was observed. In following cycles the samples begun to lose weight. All compressed samples wistand more cycles than their non-compressed counterparts. The experiment continues to find out how many cycles will the compressed...

Sediment disintegration due to air compressed by capillarity: overlooked erosion mechanism
Vaculíková, Jana ; Bruthans, Jiří (advisor) ; Kostkanová, Vladislava (referee)
Cílem této práce bylo orientačně otestovat, do jaké míry je rozpad díky vzduchu stlačovanému kapilární vodou nasávanou do sedimentu (kapilárně-pneumatický rozpad, KP rozpad) významným procesem při erozi různých sedimentů, jako jsou písky až slabě cementované pískovce, spraše, jíly, jílovce a případně i jílovité půdy. Dílčím cílem bylo především vytvořit a na několika vybraných materiálech otestovat jednoduchou metodiku, prokazující, zda sediment podlehne KP rozpadu, dále vypočítat destrukční tlak daný KP rozpadem v pórech sedimentu a porovnat ho s tahovou pevností materiálu a konečně posoudit vliv mineralogie a porosity sedimentů na KP rozpad. Pro odlišení KP rozpadu od jiných destrukčních procesů jsem zvolila pozorování rozpadu dvojic vzorků, kdy jeden byl saturován za běžného atmosférického tlaku vzduchu a druhý ve vakuu. Tato metoda je schopná odlišit KP působení od jiných erozních procesů a zároveň je přiměřeně rychlá a vhodná pro různé sedimenty a zeminy. Pozorování potvrzuje, že KP působení je schopno rozložit různé sedimenty a zeminy na jemné částice, jedná se o velmi důležitý proces rozpadu, který probíhá i ve stojaté vodě, může být iniciátorem pipingu a měl by být proto intenzivně studován. Srovnání vypočtených hodnot pórového tlaku s tahovou pevností ukázala, že vypočtené pórové tlaky...

Origin of “rock cities”, pillars and cleft-conduits in kaolinite-bonded sandstone: New insight from study in sandstone quarry where landforms recently evolve
Bruthans, J. ; Soukup, J. ; Schweigstillová, Jana ; Vaculíková, J. ; Smutek, D. ; Mayo, A. L. ; Falteisek, L.
Based on measurements of relative erodibility, ambient and water-saturated tensile strength at natural and quarry exposures three distinct kinds of surfaces were distinguished (erodible sandstone, sub-vertical fracture surfaces and case hardened surfaces). Erosion proceeded along highly fractured zones.
