Hydroforming is an advanced process in automotive and aerospace industries to form metal tubes into desired shapes by high pressure fluid. The formation of a two layered tubes has been investigated both numerically and experimentally by a pressurized fluid fed into the internal tube through a nonlinear path with no ax…

Three dimensional scaffolds are crucial for the proliferation of cells and maintenance of their differentiated functions. These functions of the scaffold are achieved via the interconnectivity, pore size/curvature, microporosity and macroporosity that influence cellular responses. At present, scaffolds were created wi…
The primary objective of this research is to develop and study newer ways to control electronic properties of correlated oxide systems using impurities. This goal has been achieved by introducing dilute localized 3d Mn impurities in place of a delocalized 4d Ru sites in a 2-dimensional Ru-O matrix and doping an electr…
On the example of dimensional PtMe/C catalysts possibilities of radiography is considered. Such possibilities are used with help of synchrotron radiation to define such nano-particle characteristics as its size, shape and sharing the particles on size due to data of a single experiment. Formulae and references on prog…
In this paper the length and times scales are discussed for dry and wetted potash particle beds. A grid mapping method of simulation is presented for a supersaturated saline solution interface at a typical particleto-particle contact point within a bed. This surface tension dominated interface will be circular in shap…
The objective of this work was to develop a "photodynamic" site-specific drug delivery methodology, whereby a drug can be released by visible light at the site of irradiation. This goal was fulfilled by connecting the target drug molecule with a photosensitizer through a specially-designed double-bond linkage. Upon vi…
Attention has been focused on electromagnetic chirality and its potential applications to microwave, millimeter wave and optical wave devices. In this work, wave propagation through a chiral periodic structure with arbitrary shape is investigated. Although perturbation theory and coupled-mode theory have been used to…
In present clause authors mark, that the nomenclature of details of space technics from tubular both hollow preparations and methods of their manufacturing are presented in many references. Basically they are resulted in the form of qualifiers from which follows, that elastomers punching with success is applied at the…
This thesis concerns the development of two new light guides, the annular lens light guide and the annular reflector light guide, into viable light distribution systems. The systems use the theory that guiding light does not require the angular distribution of light to be maintained throughout the guide. It only needs…

Solar cells are devices that convert sunlight directly into electricity by a process called the photovoltaic effect. The photovoltaic effect is simply the effect of photons from the sun hitting the solar panel and causing a chain reaction and through this chain reaction, creating ultimately two kinds of effect, the fo…
The rapidly increasing demand of oil-based chemicals calls for the development of new technologies based on other natural sources. Among these emerging alternatives, the methanol-to-olefin process (MTO) in acidic zeolites is one of the most promising. However, unraveling the reaction mechanism of such an extremely com…
Longer acting local anaesthetics which will provide prolonged nerve blockade are required for adequate management of both acute and chronic pain. It has been suggested that liposomes represent a potentially useful vehicle for sustained drug release following local administration. Thus, the aim of this thesis was to de…
The plasma parameters of SiH4/H2 plasma were examined as a function of pressure and power, where the frequency of the power source was 60 MHz. It was found that the ion saturation current takes a peak at a certain power as well as pressure.
Wax fouling is a major problem in some oil refineries. The main objective of this project was to test different surfaces with the aim of eliminating or at least reducing wax deposits in heat exchangers. Wax is separated in oil refineries by cooling the wax-laden petroleum stream in chillers and then scraping off the d…
A DC-excited atmospheric pressure glow discharge in a multiple-pin-to-plate electrode configuration is applied to the removal of trichloroethylene (TCE). To investigate the removal efficiency and the production of byproducts, FT-IR spectrometry is used. The best removal efficiency (33 %) was obtained with a gas stream…
The development of polymer/clay nanocomposites faces the enormous challenge tooffer the consistent mechanical properties for the end users. Such obstacle is derivedfrom the lack of in-depth knowledge of the effects of the individual processingparameter and manufacturing methodology. Furthermore, a more reliable numeri…
The tremendous progress in thin-film processing has opened up an exciting new field of applications for ferroelectric materials in information and semiconductor technology today. Exemplarily, the development of the Ferroelectric Random Access Memory (FeRAM) was enabled, which uses the spontaneous polarization of ferro…
