Opční strategie
Berezkin, Áron ; Witzany, Jiří (advisor) ; Witzany, Jiří (referee)
The bachelor thesis is focused on a detailed analysis of the option strategy Iron Condor. In the introductory chapter the reader is sufficiently familiarized with basic functioning of the options and with influences that affect their value. Furthermore, detailed description of the strategy Iron Condor is provided including the strategy related context, which a trader needs to be aware of in order to be able to execute the strategy. In conclusion, the strategy is backtested on the U.S. index RUT and the results are analyzed.

Determination of blood counts at sideropenic anemia, and monitoring depending on the outcome rate of iron absorption
PANOCHOVÁ, Daniela
Sideropenic anemia (iron deficiency anemia) is the most common anemia all over the world. The cause of this anemia type is lack of iron. This thesis deals with the determination of blood picture treatment results and iron absorption in patients with sideropenic anemia. In the practical part, the methods of blood picture determination as well as iron determination and the resorption curve are described. The blood picture is provided at the Clinical Haematology Ward of the České Budějovice Hospital, Corp. on the analyzer of company Beckman- Coulter Counter LH 455. Iron levels are provided in the laboratory of Clinical Chemistry of České Budějovice Hospital, Corp on the analyzer Advia. The primary goal of this thesis was proven; absorption has a significant impact on the effect of peroral treatment.

Study of properties DET, a method for pore water for sediment sampling
JAROLÍMOVÁ, Zuzana
The aim of this thesis was find out chosen properties of DET (diffusive equilibration in thin films), method for pore water for sediment sampling. This properties were: 1)the time require for equilibration between: a)distilled water in gel within DET and pore water b)sample of pore water within DET and distilled water 2)the comparison of samples pore water sampling with DET and other method 3)determination of DET properties in practice

Strukturní vlastnosti nanometrických železných částic
David, Bohumil ; Schneeweiss, Oldřich ; Pizúrová, Naděžda ; Klementová, Mariana ; Morjan, I.
Fe-based nanoparticles were prepared by the laser pyrolysis method using a cross-flow reactor in which the laser orthogonally irradiates the gas mixture of Fe(CO)5, C2H2, and C2H4. Ethylene serves as the CO2 laser radiation absorber. The as-synthesized powder was characterised by HRTEM, XRD, Raman spectroscopy, Mössbauer spectroscopy, and magnetic measurements. As observed under TEM, the as-synthesized powder consisted of nanoparticles smaller then 10 nm embedded in a pyrolytic carbon matrix. The XRD pattern exhibited three broad peaks: the first peak is assigned to pyrolytic carbon, the second peak is assigned to maghemite/magnetite, and the third peak belongs to α-Fe particles. The particle size d 2 nm was obtained for α-Fe from the Scherrer formula. The presence of α-Fe and maghemite/magnetite phases was also observed in the Mössbauer spectrum measured at 4 K.

Termodynamické možnosti a omezení pro výrobu čistého vodíku pomocí železa s využitím cyklického chemického procesu za nižších teplot
Svoboda, Karel ; Slowinski, G. ; Rogut, J. ; Siewiorek, A.
Iron offers possibility of transformation of a reducing gas ( CO, syngas, methane etc.) into hydrogen by a cyclic process based on iron oxide reduction and release of hydrogen in the next step by steam oxidation. Thermodynamics and chemical equilibrium for reduction of magnetite by hydrogen, carbon monoxide, model syngas and methane and for oxidation of iron by steam has been studied in a temperature range 400 – 850 K. Attention was concentrated also on possible formation of undesired soot, iron carbide and iron carbonate as precursors for CO and CO2 formation in the steam oxidation step. Oxidation of iron by steam is thermodynamically favoured at temperatures 400 – 800 K enabling high hydrogen yields. Iron oxide (magnetite) reduction is the more difficult step, requiring rather higher temperature and higher CO, H2 or methane concentrations in gaseous mixtures.
