	Emplacement and magnetic fabrics in dikes of syenite porphyries (Western Moldanubian Zone) Orságová, Lucie ; Verner, Kryštof (advisor) ; Žák, Jiří (referee) ENGLISH ABSTRACT We present new results of structural and magnetic (AMS) analyses of selected dikes of melasyenite, quartz melasyenite to melagranite porphyries accompanied by lamprophyres (minettes). The studied dike from the locality Nihošovice were dated by U-Pb method on zircons at 338 Ma. The asymmetric structural pattern of the studied dikes gives an excellent evidence for their emplacement and orientation of magmatic flow. The studied dikes were emplaced into: (i) Prevailing parts of the Central Bohemian Plutonic Complex (locality Malčice) and (ii) host high-grade metamorphic rocks of western part of the Moldanubian Zone (locality Nihošovice). Despite of the extensive area of occurrence, compositional variations and age of emplacement of these dikes are relatively narrow. Their geochemical and petrological compositions broadly correspond to ultrapotassic plutonic rocks (durbachites). The dikes are steeply dipping in trend ~NNW-SSE to ~W-E, with range in width between ~20 and ~25 meters. In general, our results show: (i) A relatively low degree of magnetic anisotropy (P= 1.012 - 1.152); (ii) Mostly oblate (planar) fabric, especially in marginal parts of the intrusive bodies (T= -0.091 - 0.941); (iii) Evidence for subhorizontal magmatic flow trajectory defined for a newtonian magma with typical...

	Specifics of Currency Transactions in International Companies Gregová, Silvia ; Taušer, Josef (advisor) ; Orsagova, Lucie (referee) International companies perform business transactions in different countries all over the world and must be able to manage their financial assets in various currencies. Significant foreign exchange alteration can markedly harm market value of any company. The companies use so called 'hedging' to avoid such situations. The aim of this master thesis is to analyze specifics of currency operations based on a case study in the international company and its transaction exposure. The thesis discovers that the selected company uses only two types of 'hedging'. Detailed record
