Theoretic base include structural analysis of branches, BCG matric and Porter's five forces model. Practical part is dealing with analysis of local radio station "Dobrý den" and suggests strategy and goals for years to come. One of the partial part is marketer research, whose point is to ascertain the most objective measure of quantity of radio listeners in Liberec. This indicator does not exist in official form, but this indicator is essential for local radio station on small market. Diploma work confront official measure of quantity of radio listeners measured in whole Ústecký and Liberecký region and measure of quantity of radio listeners measured in Liberec done by marketer research.

The goal of my thesis is to evaluate the importance of maize in biogas plants. The questionnaire was made to determine the parameters of hybrid corn, its harvest, subsequent silage, inclusion in the daily batch of biogas plants, and various technical and economic parameters. Twenty five biogas plants were addressed to participate in the survey. Despite the promise of anonymity, the data were obtained from only six biogas plants. Biogas plants are located in different regions of the Czech Republic, at different altitudes. The sixth and the last biogas plant is located in Austria.

Diploma thesis is focused on quantifying the maximum possible amount of usable heat energy from BGP and describing risks limiting the supply of heat energy that can be used for supplies to a heat distribution grid. This thesis deals with the material and energy flows mainly on agricultural biogas plant in Hrotovice focusing on heat supply to the elementary school buildings, hotels, office buildings and other commercial facilities. The text is mainly concerned with the measurement and evaluation of the heat amount being produced, demanded, as well as, excessive heat or its lack in response to demand of two specific customer types. It focuses on identifying the most interesting customer from the producer's point of view and quantifying differences between two main end-customers of thermal energy.

Karlíková Sabina. Biogas and its status in regional development. Diploma thesis. Brno: Mendel university, 2014 The thesis focuses on analyzing the biogas status in regional development. It primarily provides information about sustainable development, renewable energy, biomass, but attention is mainly devoted to biogas. The practical part presents the situation in Germany, Sweden and Denmark in terms of production and biogas usage, as well as the legislative framework. The result is a comparison of these three states, which, together with the analysis of the concrete situation in the Czech Republic, is the basis for the creation of a model of good practice for Czech Republic.

The diploma thesis solves an important problem with the supply of fuel in the vicinity of the competitive environment. It was found that the biggest competitors of the subject are two fuel stations in the vicinity, although smaller in the scale of trading range sale, they must be regarded as competitors. Any failure causes the transfer of customers just to them. Analysis of the survey results showed that the proportion of the sales of dry goods to total sales in the years 2010 to 2014 was 13.22 percent on average. In the assortment of dry goods there was a significant increase in sales for vehicles and a reduction in other goods. Other products consists of the following specific items: toiletries, photoes, motorway tax stickers, batteries, telephone cards and coupons and others. The sale of fuel is significantly influenced by the price (for the period 2010-2014 change of 5.06 CZK per liter) and quantity (for the same period change of 28.41 percent). Due to the current low price of fuel and the assumption of relatively same level of sale prices it will be necessary to focus on improving the quality of services provided by employees of fuel station and expanding the trade range of additional sales for motorists.

The aim of this thesis was to compare several biogas plants in the South and Central Bohemia in several respects. Overall, it was also beneficial to see how these biogas plants solve or not solve the pretreatment of the substrate, as well as the use of ancillary benefits, such as the use of heat or residual digestate. Part of this thesis is a literature search, mapping the possibilities of increasing the efficiency of agricultural biogas plants.

In this diploma thesis, the influence of chemical composition of fugate, pH value, temperature and other factors on representation of final products of nitrification during biological pretreatment of fugate produced in agricultural biogas stations was evaluated. During the experiment, fugate from biogas station Nový Dvůr with N-amon concentration in the range of 1300 - 3200 mg/l at input was processed. Results from the time period beginning on 21. September 2015 and ending on 22. December 2015 (day 0 - 93) were assessed. Nitrification reactor of five liter operational volume was placed in a laboratory at temperatures ranging from 20.4 to 25.2 degrees Celsius. During the experiment, volumetric loading of N-amon reactor ranged from 0,18 to 0,44 kg/(m3.d) and efficiency of N-amon removal from 68,6 to 96,9 percent. Hydraulic period of water delay was being decreased from 12,3 days to approximately 4,2 days during the experiment. pH value was regulated by NaOH to be approximately 7. The experiment proved that it was possible to attain the process of nitrification in the aggressive medium of fugate. It was ascertained that pH value, which determined current concentration of Free Nitrous Acid (FNA), had significant influence on representation of final products of nitrification. Concentrations of N-NO2 in the reflux from the reactor were being increased from 130 up to 1840 mg/l during the process on the grounds of pH value fluctuations and increasing FNA concentration which inhibited activity of nitrite oxidizing bacteria (NOB). The representation of N-NO2 from day 0 to day 93 of the experiment gradually increased from 19 percent up to 95 percent. Concentrations of N-NO3 from day 0 to day 3 increased from 570 to 1056 mg/l and conversely from day 3 to day 93 they gradually decreased from 570 mg/l to approximately 100 mg/l. Representation of N-NO3 decreased from 80 percent to 5 percent from day 0 to day 93 and it was not possible to retain them as dominant products of nitrification on the ground of sensitivity of NOB.

Biogas produced via the anaerobic digestion (AD) of organic waste materials is considered as an important technology in improving the environment because it solves waste management problems and simultaneously produces biogas as a main product and digestate as a by-product, which can also be used as a fertilizer. Within the rising expectations for the substitution of fossil energy with renewable energy as one of the solutions to cope with climate change, the environmental aspects of small-scale biogas plants, as widely used method for energy creation, should be evaluated in a holistic and systematic way. The use of small-scale biogas plants is mostly common for energy creation from waste in Southeast Asia. This source of energy is mainly lauded for its low costs, clean production and high fertilization effects of digested matter for crops. There are number of advantages of small-scale biogas production on farms, including also savings on firewood or fossil fuels and reduction in odour and greenhouse gas emissions from using other fuels. However, biogas plants are often poorly managed and there is lack of proper distribution systems for biogas. That results in methane being release inadvertently through leaks in digesters and tubing, and intentionally when production exceeds demand. As methane has a global warming potential 25 times higher than that of carbon dioxide, environmental advantages of small-scale biogas plants might be compromised. This dissertation intends to provide in-depth understanding about the issue with taking into accounts possible risks. Investigating of such a topic is within continuing concern about small-scale biogas technology in rural areas of developing countries. For this reason technical, social, economic and environmental assessment of small-scale biogas technology will be done. Methods of data collection will consist of questionnaire survey and focus group discussions among randomly selected owners of biogas plants, semi-structured personal interviews with local authorities and facilitators and observation. Furthermore, prediction of future development of this technology will be created.

The theme of this thesis is to assess the current state of biogas business in selected parts of southern Bohemia and the possibilities for its further development. Further processed economy on the example of a selected company and undertake structured interviews with operators of biogas plants. The first research part handles the issue of biomass, biogas, their preparation - what all have to be careful before and during construction, the legislation itsef and its implementation. In the second part analyzes the economics of selected company, which operates the biogas plant. Everything is monitored from the beginning of construction in 2012 until 2016. Each year are evaluated both financially and in terms of input material consumed. The last section is devoted to the questionnaire controlled interview with executives of three companies that operate biogas plant. The questionnaire consists of three parts - before the construction, during the implementation of biogas plants and biogas into the future of business.
