Verification of urine stability during chemical and microscopic examination
TULÁKOVÁ, Zuzana
Title of the thesis: Verification of urine stability during chemical and microscopic examination Current status: Chemical examination of urine is a basic biochemical examination and is processed in a statim and routine mode. Diagnostic strips are used for qualitative or semi-quantitative examination. Microscopic examination is often added to the chemical examination, in which either a microscope or analysers are used. Objectives: Stability of urine in chemical determination Stability of urine in microscopic determination Comparison of analysers for chemical determination Research questions: Can changes in chemical determination be observed over an extended period of time? Can changes in microscopic determination be observed over a longer period of time? Description of Methodology: The first morning urine is collected after washing the external genital area in a clean container or tube which must be free of disinfectants and other additives. For chemical determination, the following are examined: pH, protein, haemoglobin, glucose, ketone bodies, bilirubin, urobilinogen, nitrite, leucocytes, density. For microscopic determination, the following are examined: cellular elements, cylinders, microorganisms, crystals.

Application of GDA-2 instrument in practical activities of Fire Rescue Units
Rousková, Renata ; Mika, Otakar Jiří (referee) ; Čáslavský, Josef (advisor)
This diploma thesis is aimed at the use of mobile analyzer Gas Detector Array GDA 2 by Fire Brigade Units of the Czech Republic. The goal of the theoretical part was to get acquainted with this instrument and with the possibilities of its use, to describe the principle of analytical methods used in this analyzer. The experimental part was aimed on the analyses of toxic gases and vapors in the air and on the comparison of obtained result. Final part of diploma thesis evaluates the contribution of mobile analyzer GDA 2 for rapid identification of unknown toxic compounds by Fire Brigade Units of the Czech Republic.

Coaxial cables in communication networks
Hotárek, Lukáš ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
The semestral thesis is focused on coaxial cables, its development and current utilization. In the prologue of this paper, the history and origin of the cable is described with mentioning important dates and events in its development. Since the coaxial cable is type of metallic cable, part of the paper deals with the theory, parameters and characteristics of metallic cables. The theory of all basic types of metallic cables is described, that implies twisted pair, structured cabling and coaxial cable, to which is dedicated most space. The next chapter presents brief description, basic division and utilization of fiber optic to enable comparison with coaxial cable. It presents main advantages and disadvantages as well as reasoning for prevalence of use of optic fibers. The current use of coaxial cable is presented. Aside from cable television, computer and telephone networks, the coaxial cables are also used as feeder lines for transmitting and receiving aerials and as television aerial lead. Due to great possibility of utilization of coaxial cables exists a broad spectrum of cables with different parameters and properties. Therefore a separate chapter focuses on particular types of cabling, describes its significant parameters and practical utilization. The last part of the paper presents parameters of coaxial cables that can be verified and that bear great importance in praxis. The methods of proper measurement are mentioned. Aforesaid parameters include impedance, cable loss and distance-to-fault. Described are also modern analyzers that are most commonly used for measuring said parameters of coaxial cables and aerials.

Monitoring of electric power quality in the distribution networks
Kostelník, Adam ; Mlýnek, Petr (referee) ; Mrákava, Petr (advisor)
Semester project explains the concept of electrical power quality, describes its characteristics and properties defined standards. Further deals with electrical power quality measurement and analyzers that are intended for. Subsequently it focuses on the use of data communication for measured data transmission between the analyzers and collecting points. The conclusion briefly describes the basic properties of the two analyzers selected for the implementation of practical measurements.
