Major histocompatibility complex (MHC) class II molecules are polymorphic cell surface glycoproteins expressed only on the surface of the professional antigen presenting cells and they play a crucial role in the adaptive immune responses. MHC class II molecules undergo a very complex maturation process. They are synthesized in the endoplasmic …

Plasma glutamate carboxypeptidase (PGCP) is a metalloproteinase. It is able to hydrolyze dipeptides into free amino acids. The enzyme is involved in the release of hormone thyroxin (T4) from Thyroglobulin (Tg), as suggested by thyroid gland studies. Prediction from the primary structure of human PGCP suggests the presence of five …

Titanium dioxide (TiO2) in nanoparticle form has recently gained a lot of attention, in both the scientific and industrial communities. This is due to the fact that it exhibits various interesting chemical and physical characteristics, for example, a high photocatalytic activity and the absorption of incident UV light. Many applications …

A new approach for the synthesis of silver (Ag), platinum (Pt) and gold (Au) nanoparticles and their composites with hydroxyapatite (HAp) is developed via a sonochemical process. The major goal was to design physicochemical properties of material in order to achieve: (i) intensive antibacterial activity and (ii) maximal reduction of …

The task of mathematical modeling of dynamic systems from observed system behavior, widely known under the name of system identification, breaks down into two subtasks. The first task, referred to as structure identification, is to specify the model structure, i.e., the functional form of the model. In practice, the model …

SRAM-based FPGAs have become an attractive solution for many applications where a short development time, low-cost for low-production volumes, and in-the-field-programming ability are important issues. The flexibility of SRAM-based FPGAs comes from the adoption of a configuration memory that defines the operations of the circuit that the FPGA implements. It …

This doctoral thesis describes the preparation of moderately porous Y-TZP ceramics with improved flexural strength. The main field of application is dentistry, where the elastic mismatch between the Y-TZP material and tooth substance influences the survival rate of fixed partial dentures (FPDs). By introducing porosity into the bulk samples a …

KTaO3 belongs to the group of incipient ferroelectrics, which are materials important from the fundamental, as well as from the applications, point of view. It is well known in its single-crystal form; however, the processing of technologically interesting ceramics and thin films is a challenging task and knowledge of their …

With emerging need for orthopaedic implants and prolonged exposure of organism to implants also problems connected to elution of metal ions that in some cases cause adverse reactions in the human body, emerge. The main aim of our work was therefore to investigate the potential of silicon carbide (SiC) to …

This thesis investigates the use of single liquid-crystal droplets as optical microresonators and lasers. We have shown that liquid-crystal droplets can support a number of different optical modes that can be excited by introducing a fluorescent dye in the liquid crystal material and using an external excitation source of light. …
