Balance of Phosphorus and Potassium with Different Fertilizing Systems
Vašák, Filip ; Balík, Jiří (advisor) ; Jaroslav, Jaroslav (referee)
The balance of potassium and phosphorus were observed at long-term 17-year field experiments with different fertilizing systems. The field experiments were located at five sites in the Czech Republic (Červený Újezd, Hněvčeves, Humpolec, Lukavec and Suchdol) with different soil and climatic conditions. The balances were observed at: treatments with organic fertilization (sewage sludge, FYM), treatments with mineral fertilization (NPK, N, N + straw) and unfertilized control treatment, as well. Two experiments were realized: one with crop rotation (potatoes, winter wheat, spring barley) at all mentioned sites and the second was monoculture maize experiment at Červený Újezd and Suchdol sites.
The positive balance of phosphorus was at the treatments with sewage sludge (SS) as well as with farmyard manure (FYM) application and at the NPK treatment. The average phosphorus balance ranged between +1.8 and +14.0 kg/ha/year at the treatments NPK, between +7.2 and +21.6 kg/ha/year at treatments with FYM application and between +66.7 and +75.6 kg/ha/year at SS treatments, respectively. The balance of phosphorus with a higher dose of sewage sludge reached +249.6 kg/ha/year. The average negative balance of phosphorus (from -27.5 to -13.4 kg/ha/year) was calculated at the treatments N and N + straw. The balance of control unfertilized treatments ranged between -21.9 and -11.0 kg/ha/year.
The average positive balance of potassium in the experiment with crop rotation was estimated at all of FYM treatments. The balance reached the values from +2.3 to +30.1 kg/ha/year. On the contrary, the balance at FYM treatment in experiment with maize monoculture was negative (-15.2 kg K/ha/year). The balance of potassium in experiment with crop rotation ranged between -9.5 and 33.2 kg/ha/year at the NPK treatments. Similar values were obtained in the experiment with monoculture, where the balance at the NPK treatment reached +32.1 kg K/ha/year. The negative balance of potassium (between -69.2 and -8.9 kg/ha/year) was obtained at treatments with sewage sludge application. The most negative balances were calculated at N and N+straw treatments (-104 to -55.0 kg/ha/year) and as expected at Control (-73.2 to -43.6 kg K/ha/year).
The bioavailable soil phosphorus and potassium contents changes were in most cases in close relation with balances calculated. Soil variability in observed soil factors was found in the plots and confirms the assumption that the system of fertilization affects crop yields.

Schořovská, Kristýna ; Kukalová, Gabriela (advisor) ; Jaroslav, Jaroslav (referee)
This thesis is focused on insurance for foreigners in the systems of public and commercial health insurance in the Czech Republic. Evaluate the effects that would result from the integration of foreigners into the public health insurance, based on the gross costs of the annual reports of commercial insurers and based on the income statement. Work gives a comprehensive overview of the current health care system in the Czech Republic, and design optimization.
The first part is devoted to health systems, which are used in the world. They are defined by their key characteristics as well as their advantages and disadvantages. The second part is devoted to public and commercial health insurance in the Czech Republic, where the two systems are compared. In the third part we are analyzed the conditions, limitations, exclusions and insurance products offered price between commercial insurers. There are also quantified the costs and revenues associated with the inclusion of commercially insured foreigners in public health insurance. In the final part evaluates the balance of income and expenditure, which would hold a public health insurance, including the formulation of their own opinion on optimizing the system.

Design of a constructed wetlands for wastewater treatment at Lhota u Nahořan
Havlová, Eva ; Vymazal, Jan (advisor) ; Jaroslav, Jaroslav (referee)
The thesis deals with the constructed wetlands (an aquatic plant root filter).
It characterizes a principle of effluent treatment, types of wetlands and treatment
process.
A part of the thesis is focused on wastewater sampling sites in Lhota u Nahořan
(situated nearby Náchod in Hradec Králové region) and on process of their
evaluation. It also describes the location and method of wastewater flow
measurement. The collected indicators of pollution and flow rates of the brook
in Lhota were used for hydro-technical calculations required for their own
constructed wetland project in Lhota u Nahořan.
There are two design options suggested for this given location with a population of
73 residents and where the average wastewater flow, as measured, is 113.18 m3/d.
The target rates of the ammonia nitrogen and the total phosphorus in the effluent
were determined to be 0.5 mg/l.
The first version of the solution was according to the horizontal and the other to the
vertical filters.
The main advantages of this this solution using aquatic plant root filters include
a naturally replicated process of wastewater treatment and low operating costs. Also
for these reasons, this green zone method is increasingly used for homes, holiday
residences and communities.

Paimová, Barbora ; Plachý, Vladimír (advisor) ; Jaroslav, Jaroslav (referee)
Measurement of effect of L-carnitine by ergospirometry Summary The intention is to determine the effect of L-carnitine on fatty acid metabolism. Values like volume of utilized oxygen, performance and respiratory quotient were chosen for evaluation. The study is a randomized and placebo-controlled. The testing was performed on a treadmill with gas sensing device Cortex Metalyzer 3B and sporttester Polar RS 400. The measurement was adjusted compared to the pre-set test program. The reason was detecting a change in fatty acid metabolism, which takes place under aerobic conditions and starts later. Participants were recreational and performance athletes. Paired t-test and percentage change were used for evaluation. There was no change in the volume of utilized oxygen, performance and respiratory quotient. This study does not match with the majority of similar trials, which indicate the reduction of the respiratory quotient, reduced lactate levels, markers of increased oxidation of fatty acids and the other markers of aerobic metabolism.
