Ecological demands of the selected planktonic algae and cyanobacteria from the order Nostocales. Light intensity and temperature optima of the water-bloom dominant species in the ponds and reservoir in the Czech Republic.
KOHELOVÁ, Hana
This thesis is aimed on cyanobacterial water blooms. It deals with the composition of cyanobacterial water blooms, factors which cause its emergence, effect it has on environment, termination of cyanobacterial bloom and ways of how to restrict it. My thesis contains the chapter devoted to the cyanobacterial bloom characteristic, which gives them advantage over other organisms in plankton and over other cyanobacteria as well. It also contains general description of fishponds and reservoirs and locality description (fishpond Svět and Rod, water reservoir Římov, Jihočeský kraj), which were the sources of species tested in this experiment. The aim of the experiment was to find out the optimal temperatures and light for the growth of seven strains of cyanobacteria and one species of green alga. The experiment was conducted by cross-table gradient of temperature and light method (KVÍDEROVÁ a LUKAVSKÝ, 2001. Data of the strains growth in different combinations of temperature and light intensity was processed in program Statistika (ANONIMUS, 1996). Valence of each strain has its maximum and minimum values. In their mean, there is an optimum for the growth. Charts depicting maximal-minimal values and optimum of strains for temperature and light were created in Microsoft Excel. Details between temperature and light demand of strains were tested by PCA analysis in program CANOCO 4.5 and visualised by CANODRAW (TER BRAAK a ŠMILAUER, 1998). It resulted in particular values, which are comparable with similar laboratory tests.

Historical evolution view on the substance of the light
ANDERL, Jan
The principle of the seminar work is to create the skilled text which could be used such as educational material for other students to they can better understand to the evolution of opinions on the substance of the light. The work is composed from the five parts. Each part is enplaining the view of the scientists on the substance of the light from the certain period. The first part is connected to the era of the antiquity {--} the period of the first contentions about the substance of the light. The second part is intent on the era from the fifth century (Optical theory) to the nineteen century (Young theory ). The third part refers to the 20th century. The fourth part apply to the present, to the newest researches and work in the sphere of the light. The fifth part is created by the biographies of the most meaningful people who have been working on the question about the substance of the light.

Strategická analýza společnosti Technika denního světla s.r.o.
Kolářová, Šárka ; Dvořák, Jiří (advisor) ; Lešetický, Ondřej (referee)
Práce se zaměřuje na zhodnocení dosavadního vývoje společnosti Technika denního světla s.r.o. pomocí různých analytických metod. V první části práce je uvedeno teoretické shrnutí strategické analýzy, na které navazuje seznamení se společností Technika denního světla s.r.o. Praktická část v sobě zahrnuje jak analýzu interní, tak externí z makro i mikro pohledu. Největší důraz je kladen na analýzu hodnoty zákazníka, jež je stěžejní součástí externí analýzy. V interní analýze je pak největší část věnována lidským zdrojům.
