The thesis is divided into several parts. At first, there are written information from the laws and decrees concerning the lead pipeline, drinking water, observance of lead concentrations in drinking water, etc. Then the water connection, the ownership relations to the connection and the materials used for the water connection are defined. The next chapter deals with lead, lead pipeline, lead in drinking water and the legislative requirements for lead content in drinking water. Other part is about the health risks of lead in drinking water. These theoretical parts follow the practical part, which focuses on drinking water quality testing, which was in contact with the lead pipeline. This section describes drinking water sampling principles for determining the concentration of lead, the locations where the samples were taken, the methods used to determine the concentration, the description, the results and the evaluation of the information. The last chapter shows the methods and materials that remove lead from water.

The first part of the thesis deals with the issue of indoor climate in school buildings. The second part deals with the design of the heating system in the extension of the primary school, including the design of the source and the reconstruction of the source for the existing building in a variant solution. The last part of the thesis is devoted to experimental measurement of indoor air quality in elementary school.

This work focuses on the research and comparison of several types of air purifiers. It clarifies the principles of filtration and describes the basic types of air purifiers. Part of this work is designed methodology of measurement for comparison of filtration efficiency and filtration rate. The experimental part of this work contains the measurement and comparison made for two types of air purifiers. Selected purifiers were De’Longhi AC230 with mechanical filters and ionic air purifier Ionic-CARE Triton X6. Within the framework of this work an experimental set-up was constructed in the home environment for the simulation of real conditions for the function of the air purifiers. The measurement results provide information about aerosol number concentration process during the measurements and evaluation of filtration efficiency of air purifiers.

Diurnal changes of initial and total activity and content of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) under conditions of ambient (350 µmol mol-1) and elevated (E = 700 µmol mol 1) concentration CO2 were measured in needles of Norway spruce. Needles of Norway spruce were taken on 22th July in two-hours from 3:30 a. m. till 10:30 p. m. The Rubisco activity was determined by spectrophotometry, the Rubisco content was detected by SDS-PAGE. The Rubisco activity was in most samples statistically significantly lower in needles cutlivated under ambient carbon dioxide then in needles cultivated under elevated carbon dioxide. Diagrams of the Rubisco activity shows absence of night inhibitor CA1P. The Rubisco activity was directly proportional to the intensity of photosynthetically active radiation in time from 7:00 a. m. till 7:30 p. m. The Rubisco content was statistically significantly higher in needles of Norway spruce cultivated under ambient carbon dioxide than in needles cultivated under elevated CO2, which shows acclimation of the Rubisco content during long-term effect of elevated CO2 concentration.

In this diploma thesis protein content of gliadin fractions in winter wheat (Triticum aestivum) var. Bohemia was studied. The crop was cultivated in conditions with ambient (AC) and elevated (EC; 700 mol•mol-1) carbon dioxide concentration. Moreover, half of the samples was fertilized with nitrogen in an amount of 200 kg•ha-1. Other observed environmental factors were drought and UV radiation. The gliadin proteins were separated by A PAGE method and quantified by computer densitometry. Generally the protein content within , and gliadin fractions varied, while the protein content of gliadins remained unchanged or almost unchanged. Clearly the nitrogen fertilization had the most pronounced impact on the gliadin protein content and it significantly increased the protein content in wheat grain. Most subfractions reacted in conditions of AC, drought and without UV radiation and in conditions of EC with natural rainfall and UV radiation. The interaction of nitrogen fertilization with UV radiation (AC, drought) was significant and so was the interaction of nitrogen fertilization excluding UV radiation (EC, drought). The interaction of nitrogen fertilization and natural rainfall significantly increased the protein content in conditions of AC without UV radiation and in conditions of EC with UV radiation. EC alone and the interaction of EC with other factors had only a small impact. The impact was the most pronounced in interaction with nitrogen fertilization. EC with nitrogen fertilization (drought without UV radiation) increased the gliadin protein content and EC excluding nitrogen fertilization (drought and natural rainfall with UV radiation) decreased the protein content.

This diploma thesis deals with effects of nitrogen supply, drought and UV radiation on wheat grain quality under the ambient and elevated concentrations of carbon dioxide. The theoretical part deals with the global climate changes, greenhouse gases and especially with effects of elevated concentrations of carbon dioxide on plants. Also, it is dealt with effects of elevated concentrations of carbon dioxide on the wheat grain quality. In the experimental part nitrogen content by the Kjeldahl method, contents of dry and wet gluten, Zeleny test, falling number and content of starch in the wheat samples were determined. The results of this study confirmed affecting the quality of the wheat grain from the elevated concentrations of CO2, nitrogen fertilization, drought and UV radiation. The most evident was the influence of nitrogen nutrition, fertilization positively affected the quality of grain, there was an increase in content of crude protein, gluten content, value of Zeleny sedimentation test, and falling number. As a result of the increase in protein content was also a decrease in starch content. Due to increased levels of carbon dioxide protein content and gluten, Zeleny sedimentation test values and falling number decreased and conversely starch content increased. The decrease of Zeleny sedimentation test by the influence of elevated CO2 concentration was fully compensated by nitrogen fertilization.

Master´s thesis is focused on development of electrodes used in alcaline accumulators, by using new kinds of materials and compounds. Basic possitive eletrode was made of nickel, on this electrode were applied new layers of Ni(OH)2 by using the method called electrodeposition. For electrodeposition was used solution with Ni(NO3)2 in diverse concentrations. Later on, this material was enriched with aluminium admixtures to increase stability of alfa modification in Ni(OH)2. These concentrations were measured and analysed in diagrams. For measurement was used device Biologic. The diagrams were commented with recommendations for production use in accumulators.

This thesis deals with dependence of heat transfer coefficient on rate of air concentration in the water. Main idea appears from gas dissolvability in water depending on pressure, Henry's law and Newton's law of cooling. There had been an experiment made to verify the hypothesis.

The thesis is aimed at the modeling of releases of hazardous substances to the designated software tools. The work consists of three parts. The first part is theoretical, which deals with hazardous substances and their legislation, accidents in industry, physical models of leakage and dispersion of hazardous substances and factors influencing their spread in the air and finally software tools. The second part, experimental, describes some software tools and their subsequent modeling. The third part is devoted to the results of modeling and analysis of selected software tools. The aim of the thesis is to analyze selected software tools for modeling the release of hazardous substances, to compare their explanatory power and potential use.

Vliv hyaluronanu na micelizaci tenzidů byl studován různými fyzikálně-chemickými metodami. Byly zvoleny dva kationaktivní tenzidy, a to tetradecyltrimethylammonium bromid (TTAB) a cetyltrimethylammonium bromid (CTAB). Metoda izotermické titrační kalorimetrie byla využita pro stanovení entalpie micelizace, tenziometrie popisuje povrchové vlastnosti daných vzorků. Byl sledován také vliv různé molekulové hmotnosti použitého hyaluronanu a délka alkylového řetězce tenzidu na agregační chování daného systému. Výsledkem jsou hodnoty kritické micelární nebo agregační koncentrace tenzidu. V neposlední řadě se diskutuje využití agregátů hyaluronan-tenzid jako možné nosiče pro cílenou distribuci léčiv.
