Je měnová politika ECB vhodná pro všechny státy eurozóny?
Machala, Martin ; Řežábek, Pavel (advisor) ; Štěpánek, Pavel (referee)
The theoretical part of this thesis is devoted to the position, goals and tools used by the European Central Bank, which is bound with the development of monetary policy influenced by the time period starting with foundation of the EU central bank to current days, full of problems with eurozone. The main aim of this thesis is to prove whether the EU central bank monetary policy is suitable for all eurozone countries or just some of them. The main tool for the analysis is the optimum currency area theory, which compares the inflation of countries which are members of eurozone, with the monetary policy of the European Central Bank. The results confirm that in the long term, the inflation in eurozone countries which are currently in major economic problems substantially differ from the average inflation of the eurozone. From results of the analysis it is obvious that there is no convergence in inflation. Convergence in inflation is an important condition when creating an optimal currency area. Because of its absence the next statement can not be true. A common monetary policy for all countries of the eurozone is not always optimal.

V příkladové studii na Bílině se ryby na úrovni společenstva projevily jako dobrý a rychlý indikátor ekologického stavu toku, avšak pro indikaci chemických látek v řece je nutné hodnotit specifické parametry na úrovni jedince.

Fish assemblage of the polluted middle part of Elbe River
Švanyga, J. ; Valová, Zdenka ; Janáč, Michal ; Bialek, M. ; Machala, M. ; Jurajda, Pavel
In July 2005, four stretches of the River Elbe were surveyed. In each river stretch, 3 sections were sampled: under the weir, middle zone and above the weir. Adult fish were sampled by boat electrofishing, juvenile fish by seine netting and electrofishing . Totally, 22 species of adult fish were caught. Bleak, chub and roach were the most abundant adult species. Species richness was similar in all river stretches. Fish abundance decreased slightly downstream, both between and within river stretches. 14 species of juvenile fish were caught, most of them represented by a few individuals. Bleak and bitterling were the most common juvenile species. Chub and common bream were co-dominant species in some sections. Fish assemblage of the surveyed sections was relatively poor with a negligible natural reproduction . Despite of the strong pollution source, geomorphological and hydrological stream character seems to be the most important for fish assemblage.

Inhibition of gap junctional intercellular communication by polychlorinated biphenyls: inhibitory potencies and screening for potential mode(s) of action
Bláha, L. ; Vondráček, Jan ; Upham, B. L. ; Machala, M.
The aims of the present study were to determine potencies of a series of environmentally relevant PCB congeners to inhibit GJIC invitro, and to screen for intrcellular signaling pathways potentially involved in GJIC downregulation by PCBs. It was found that a number of nonplanar PCB congeners are efficient inhibitors of GJIC in vitro, and that a model compound, PCB153, does not act via activation of PKC or ERK1/2, which is contrast with the effects of protoypical inhibitors of GJIC, such as TPA or EGF.
