Methods of Processing of Flat Glass
Tichý, Vojtěch ; Hruška, Pavel (referee) ; Molliková, Eva (advisor)
This "paper" disserts the flat-glass processing methods in the context of history. It outlines the former as well as the current ways of flat-glass production, mentions the possibility of the flat-glass further fabrication using the fritting method in the electric furnace and engages the faults and errors of this technology.

Analysis of operating fluids properties
Chrobák, Jan ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This diploma thesis is focused on introducing the mathematical and physical fundamentals of viskosity, density and refractive index of liquids and methods of its measurement. Based on available literatures specify review of areas in which the measurement of dynamic viscosity is used for evaluation the actual state of liquid materials. Discuss the possibility of using for example variables to determine the concentration of fat in milk and ethanol in alcoholic beverages. The sample of liquid to realize the practical measurements.

Influence of cellulose ethers on rheological properties of lime
Hegrová, Michaela ; Rovnaník, Pavel (referee) ; Vyšvařil, Martin (advisor)
The subject of this diploma thesis is a study of the influence of cellulose ethers on the rheological properties of lime. The theoretical part focuses on rheological parameters, techniques and test equipment used in rheology measurements. Various types of cellulose ethers and their influence on the rheological properties of fresh mortars are described. The practical part deals with the study of the influence of different types and quantities of cellulose ethers on the properties of fresh lime pastes and mortars. The results were obtained from measurements on a rotational rheometer with a special geometry for building materials. Measuring methods used were flow and oscillatory tests. Yield stress, viscosity and flow index were determined by the flow measurement. The stability and stiffness of fresh materials were determined during the oscillation measurements. The measured results are then evaluated and compared.
