Technology for liquefaction gases and its use and distributing
Štěpánek, Jindřich ; Kracík, Petr (referee) ; Škorpík, Jiří (advisor)
This thesis deals with technologies for gas liquefaction and storage. The first section summarizes the development of liquefaction technology using expanders and throttling valves, followed by current technology. This is especially a rotary expanders. The storage technology is the above-ground storage of cryogenic tanks. The thesis includes proposals turbine wheels for liquefaction lines and included two proposals liquefaction cycles.

Heating curve calculation
Štěpánek, Jindřich ; Charvát, Pavel (referee) ; Hejčík, Jiří (advisor)
The bachelor thesis examines the question of heating, more precisely heating depending on climatic conditions of the environment in which the heated entity is situated. It summarizes the information necessary for calculating equithermal dependency as well as the information about the types of heat loss of buildings and their calculation. There is also basic information about the heating elements, their types and characteristics. Using all the information, a model calculation of one point weather compensation curve for the chosen reference room is determined. Further, another way how to get the heating curve is mentioned there, its model calculation is done and the advantages and disadvantages of this method are described.

The role of freight forwarding company arranging LCL export shipment to USA
Štěpánek, Jindřich ; Novák, Radek (advisor) ; Bican, Danil (referee)
This diploma thesis describes ocean freight LCL export shipment from the Czech republic to USA. Freight forwarder not only arranges the transportation, he can also offer complementary services like warehousing, packing or customs clearance of shipment. After definition of freight forwarding I described current situation on the ocean freight transportation market, especially infrastrucuture and means of transportation. There are more strict rules for shipments imported to USA. In cooperation with customs declaration I tried to describe all the steps, that are necessary to start arranging export shipment. The last part of diploma thesis describes specific business case of arranging LCL export shipment to USA.

Logistics in catering and implementation of HACCP
Štěpánek, Jindřich ; Mervart, Michal (advisor) ; Kruisová, Hana (referee)
The bachelor thesis describes the processes of logistics in a small company providing catering services and implementation of a method based on HACCP (Hazard Analysis and Critical Control Points), which is recommended for the operaters of eating facilities. The HACCP certificate is internationally regarded and it can be a complement for ISO 9000 certificates. The thesis does not describe running complete HACCP system, but only a partial system based on HACCP and also necessary hygienic moves, which are mandatory for all the eating facilities.

Gaseous products of microbial decomposition of organic pollution in constructed wetland used for wastewater treatment.
ŠTĚPÁNEK, Jindřich
This master thesis is dealing with monitoring of gaseous products of microbial decomposition of organic pollution in constructed wetland. This wetland was used for wastewater treatment in a village Slavošovice, Czech Republic. Emissions of CO2, CH4 and N2O were measured in one treatment bed of the system. The emissions were quantified, their seasonal course was followed, and the main factors affecting gaseous emissions were identified. Only 3 % of total C emissions were in form of methane, N2O emissions were negligible and only 1,5 % of nitrogen denitrified were in form of N2O. Carbon and nitrogen balances of the system were estimated.
