The aim of this work was focused on the determination of pesticides concentration in water solution. Pesticides are indissoluble in aqueous solutions and impedance or voltametric/amperometric response of the pure water and water with pesticides is identical. Therefore was necessary find a way how rapidly, effectively and economically measure the pesticides concentration. One way is measurement of conductivity with electrochemical microsensors after enzymatic reaction.

The first part of the thesis deals with electron microscopy and physical model fluid flow. In the next part, a three-dimensional model is created in programme SolidWorks. It is the model of scintilating detector with aperture or screen with three hundred little apertures. These models are submitted to analysis focusing on investigation of the gas flow at different pressure in chamber of specimen ESEM using Cosmos FloWorks system. The results of the analysis of both apertures variants are compared with the request to minimize the pressure in the trajectory of the secondary electrons as well as in the chamber of specimen.

Also describes touch control and writing using the virtual keyboard of smartphones. The second part describes the analysis and projection of virtual keyboard with emphasis on ergonomic use for handicapped person. One solution is selected and programmed for operating system Android. Thesis contains complete procedure of application developing, starting with first request, through designing, programming and ending with debugging, testing and release application on Android Market.

This work deals with the flow of gas in the scintillation detector. Thesis describes the function of an electron microscope, the composition, distribution and development of microscopes from the earliest to modern. The work also includes familiarization with SolidWorks 3D modeling in which is the electron microscope modeled and Cosmos FloWorks in which they are carried out simulations of gas flow. The paper is focused on the flow of gas in various shapes of the screen and various pressures in chamber of specimen. The results of the analysis of both apertures variants are compared with the request to minimize the pressures in the trajectory of the secondary electrons of well as in the chamber of specimen.

This work deals with design of PC remote control, which is able to control computer with operating system Windows and Linux using Wifi connection. There was also created necessary support software for both operating systems. Communication was secured by ciphering algorithm.

The thesis is focused on the design of a scintillation detector with one screen for environmental scanning electron microscope. At the beginning of the work is an introduction to microscopy. Further work is focused on the description of ESEM microscope and a scintillation detector. The following chapter is devoted to the dynamics of flow. They list the types of flow and mathematical description of equations. The next chapter is about using the software and the way of solution of flow. In the following chapter describes a proposal of the diaphragm and extraction method of the detector area. They are described some of type aperture. The last chapter is the conclusion, where the work is summarized.

The work is dedicated to the production of a thick film with resinate paste on a ceramic substrate based on a proposal test motive. It introduced the optimization of the workflow leading to the successful realization of the layer. Using an electron microscope, it is performed evaluation of the quality of resultant layer and analysis of the composition of the paste. In the last part of the work it is carried out measurements of temperature and electrical properties of resinate paste.

This thesis deals with a design of a circular draining machine. The aim is to design a machine that complies with the respective requirements. The machine is assembled in a line for the preparation of paper stock, which is further processed for final paper production.

This thesis deals with the structural design of hydraulic raking screens placed before a sewage treatment plant. The first part describes various possibilities of water treatment from individual particles. The second part deals with basic parameters of screens and calculations of propelling power for previously chosen structure. Furthermore, a strength check of structure under the most unfavourable load is performed. Drawings of the whole assembly of hydraulic raking screens, plus a few selected components are attached to the thesis.

This thesis pays attention to electrochemical sensors for the detection of glucose. The theoretical part deals with the technology of thick film, their application and firing. It is further described electrochemistry, electrodes used in electrochemistry and analytical methods based on electrochemical reaction. End of theoretical part deals with electrochemical biosensors for detection glucose using special electrodes based on enzyme glucose oxidase. In the experimental part is processed amperometric measure for detection glucose using screenprinted sensors S10 and S8 with immobilized enzyme glucose oxidase. Next was studied effect of plasma, dissolved potassium chloride, storage, ascorbic acid and the reproducibility of the sensors.
