Analýza výživy a ekonomických ukazatelů produkce mléka v daném zemědělském podniku
ZEMAN, Ondřej
Under operational conditions the concept of nutrition and efficiency of milk cows (the breed: Holstein Friesian cattle) was assessed in the chosen agricultural enterprise during the years 2015 and 2016, as well as the production of feed for the milk cows and the economical aspect of milk production during the period of decreasing prices of its purchase. The thesis embodies the assessment of the negative impact of a low rainfall total in the locality of monitored enterprise specialising in the production of bulky feed. Because of this fact the feed amount of productive milk cows were changed in 2016. An interannual decrease of milk yield about 1,92 l per 1 peace of kettle and 1 day was recorded on the grounds of the change of feed doses. The decrease in efficiency and consequently the decrease in delivery of market milk to trade in 2016, together with low prices of purchase of milk, had direct influence on a low economical profits in the area of milk production and milk-cows breeding of the monitored enterprise.

The creation of videotutorials for the University of Economics, Prague
Zeman, Ondřej ; Šedivá, Zuzana (advisor) ; Kupec, Michael (referee)
The purpose of this bachelor thesis is to acquaint readers with new possibilities of teaching by using information technology and its application, when making learning material. The main outputs of this thesis are video tutorials, which serve as an education support for the course 4IT110 Use MS Excel in business practice taught in the University of Economics, Prague. However, it may be useful to other students of different courses. The process of making tutorials is described from the very beginning by specifying methodology, creating model exercises, subsequent testing of tutorials by students and optimisation of videos according to their suggestions and comments.

Influence of supplementary feeding on productive indicators of fishes
ZEMAN, Ondřej
This paper evaluates the influence of supplementary feeding of multi-species stocks with various densities on productive indicators of the common carp (Cyprinus carpio L.) and conversion of feeding. The chosen issue has been researched as a feeding experiment for 145 days at the joint-stock company Rybářství Třeboň, in four ponds of the Naděje fish pond system (Nadějská rybniční soustava) and two control fish ponds situated in the near of the village Ponědrážka. In the ponds, there were two different stocking densities. Fished were supplementary fed by heat treated wheat. The achieved results compare fishes' growth depending on the feeding conversion in various breeding condition.

Study of stagnant water occurrences and dripping waters in caves: Chemical composition and remarks to corrosion of dripstones
Zeman, Ondřej ; Bruthans, J. ; Filippi, Michal ; Vysoká, H.
Slight stagnant water occurrences (drops) were studied in four caves in the Czech Republic and Slovakia. Major components were analyzed (Na+, K+, Ca2+, Mg2+, SO42-, Cl-, NO3-), pH, conductivity and temperature were measured in the field. Results are shown in table 1. Waters coming from condensation differs by higher amount of sulphate and some other components if compared with dripping waters.

Environmental tracers (18O, 3H, CFCs, SF6) exploitation for study of mean residence time and flow pattern of dripping water and karst springs (Moravian Karst)
Bruthans, J. ; Zeman, Ondřej ; Jež, M. ; Himmel, J. ; Buzek, F. ; Melková, J. ; Oster, H. ; Geršl, M.
Mean residence time and flow pattern was studied in unsaturated zone of Ochoz Cave in southern part of Moravian Karst by means of 18O in the years 2001 to 2003. The results of study showed relatively long residence time in the unsaturated zone (about 50% komponent with residence time exceeding one year). The proportion components coming from different reservoirs were computed from two components (soil/epikarst; meltwater). The results clearly indicate, that more than 50% of water (nearly 100% in 2003) in dripping waters was derived from soil/epikarst water, which originate from (late) summer precipitations (heavy 18O content)! It means that infiltrating snowmelt water was expelling (by piston flow effect) the summer water from soil and/or epikarst. Water from snowmelt was then lost by evapotranspiration in summer time. If this effect is common in Langer period, it can change composition of d18O in dripping waters and hence also in dripstones precipitating from these waters.

Mezinárodní smlouvy v českém právním řádu
Zeman, Ondřej ; Trávníčková, Zuzana (advisor) ; Sladký, Pavel (referee)
In the second, common part describes public international law and it's relation to the national law. Subsequently the system of sources of public international law and application of the international treaties to the system of the national law. In the third, analytical part describes relationship between international and the Czech law, it's historical development and present situation and the relation of the Czech national law to the acquis communautaire as well.
