Power sources in the Czech republic concentrated on using biomass
Vacek, Tomáš ; Liedermann, Pavel (referee) ; Špaček, Jaroslav (advisor)
This article introduces independent sources of electric energy in the Czech Republic, the different types of power plants, their productivity and the quantity of electric energy delivered to the main distributor. In our country, as well as around the world, commonly used fuels are fossil fuels- coal, crude oil, and gas. As the demand for energy grows, those supplies are slowly running out. Not to mention that those fuels have a negative environmental impact. They are a source of carbon, which causes damage to the atmosphere and leads to global warming. Power plants which do not produce carbon are much safer for the environment, and much more productive. However, the residue of this energy is challenging to dispose of. Nuclear energy has common attributes with renewing the sources of energies that are extremely friendly to our environment. Nuclear power plants also produce enough energy and with the usage of Fourth generation reactors, they will be able to recycle the nuclear fuels. Today, more importance is put on renewing sources which are more gentle for the environment. In the near future, CEZ Company, the largest producer of electric energy is planning to use water energy. Water energy comes from water plants or dams. Other ecological forms of energy include geothermal and solar energies. These two types of energy are not as applicable for our geographical position. Geothermal energy is commonly used on islands where there is an abundance of natural hot springs. The most discussed source of energy is bioenergy. It uses natural wood sources, recycled wood products, and applies bioenergy as a main source for thermal power plants.

Analysis of packaging technologies for packaging soft drinks
NOVÁK, Martin
The main objective of this thesis is an analysis of packaging technologies for packaging of soft drinks from aspect of suitability of logistics operations, logistics costs, respecting the customer's needs and the impact on the environment. Secondary objective will be the formulation of the critical factors determining the current packaging technology in the beverage industry in order to be able to propose measures to ensure the optimization of producing and packaging soft drinks. Results of the thesis came to the fact, that it would be appropriate to create a completely new system of producing and packaging soft beverages. Beverage itself would be produced by postmix technology. The postmix device would be placed directly into the markets. The customers will have the possibility to choose to use their own bottle or bottle provided from the selling machine attached to the postmix device. This means that the bottle will be used more times and the final price of the product will decrease. The customer will pay only for beverage itself not for the bottle, which costs make more than 3 times more than own beverage. Using this technology is mainly suitable for newly incoming sellers, which do need to gain an market advantage and also decrease the starting costs.

Analysis of beverage packaging technologies within certain food production plant
PROKOP, Zdeněk
There are many degrees of freedom within packaging technologies. Every product could be packaged in several ways. However the final step for transportation is common for every piece of them, a trailer, a container or any other handling unit of higher grade. The food production plant which was allowed to be considered is one of the large Czech breweries. Like in every production plant, there are many packaging materials needed. Application of ABC method rescues capital sources for more effective usage. Czech beer market is highly saturated. Many domestic breweries concern to invest they forces to export markets. However they need to change and improve some of their packaging technologies. For example: bottling, carton or cardboard packaging line improvement, or taking into an account new innovative keg packaging opportunities.

Water Footprint. Calculation of water footprint of wheat, maize, sugarbeet and tomatoes in the Czech Republic
Landová, Lucie ; Hák, Tomáš (advisor) ; Vrba, Jaroslav (referee)
Fresh water is a renewable resource but it is also finite. Around the world, there are now numerous signs that human water use exceeds sustainable levels. Groundwater depletion, low or nonexisting river flows, and worsening pollution levels are among the more obvious indicators of water stress. Satisfying the increased demands for food, water, and material goods of a growing population while at the same time protecting the ecological services provided by natural water ecosystems requires new approaches to using and managing fresh water. There has been little attention to the fact that the organization and characteristics of a production and supply chain does actually strongly influence the volumes of water consumption and pollution that can be associated with a final consumer product. Uncovering hidden link between consumption and water use can form the basis for the formulation of new strategies of water governance. That is why in this diploma thesis we focus on introducing the indicator of freshwater use that looks not only at direct water use of a consumer or producer, but also at the indirect water use - water footprint. At a global scale, most of the water use occurs in agricultural production. That is the reason why we have chosen water-intensive goods like crops to show how water footprint...

Artificial insemination
Svobodová, Štěpánka ; Semecký, Vladimír (referee) ; Nachtigal, Petr (advisor)
v anglickém jazyce There have been several reasons for my choice of this topic. One of them is the fact that the topic is very interesting itself. As a second reason, it may be said, is the high occurence of infertility in population and also the fact that literature on this topic is not very frequent and available. I have attempted to round off information from a variety of sources into one text and thus simplify further search for necessary information. The thesis deals with current situation of infertile couples in the world. It deals mostly with the problem of origin and causes of infertility, it describes the factors that should be avoided and also when an expert should be contacted. The basics of this theses is, of course, the anatomy of reproductive organs, woman's period, the course of ovulation, tests for finding out the most fertile time, using hormones etc. Part of the thesis is thus devoted to this issue. Towards the end of the thesis, it is devoted to assisted reproductive techniques and medical examination preceding the pharmacological treatment and also with disposing of issues leading to infertility.

Packaging and Its Influence on the Effectiveness on Logistic Operations
PECHOVÁ, Jaroslava
The topic of my work is packaging and its influence on the effectiveness of logistic operations. The main aim of my diploma work was an analysis of portfolio of products of a packaging industry which enters distributive chains in the sphere of an elected sortiment group from the point of view of their applicability for logistic operations. I acquired information for elaborating this work from the company Schenker, Ltd., Jamall, Inc. and next from shopping chains. I compared pallets which are used by the company Schenker in logistics. In the company Jamall I dealt with a portfolio of furniture and its influence on effectiveness of logistic operations. In shopping chains I dealt with the matter of conveniency or inconviency of packaging of non-alcoholic beverages. Next I applied a properly elaborated questionnaire aimed at environment and packaging. I applied the method of observation, controlled interview, analysis of documents, processing data from the operations register file and questionnaire investigation for acquiring necessary information. I made a conclusion that a proper choice of packaging has an essential influence on lowering costs involving storage, manipulation and transport.
