Abstract:
In this paper, we report the optimal conditions for the isolation and preconcentration of branched chain amino acids (BCAAs) – leucine, valine and arginine from different types of matrix, such as tissue, plasma, blood, bacteria or cells. Herein, we focused on the synthesis of paramagnetic particles able to isolate and immobilize amino acids and thus preconcentrate it for subsequent analysis on ion-exchange liquid chromatography with VIS detector.

Abstract:
Application potential of colloidal particles and nanoparticles is related to their size, shape and other physical and chemical properties. Those properties can be influenced by various ways of synthesis, while the presence of reducing agent and modifiers (polymers, surfactants) are the most vital ones. [..]

Abstract:
The aim of the present work was to deposit thin polymer-like films fulfilling several criteria in order to enable their industrial application as protective coatings on various materials, for example plastic substrates. Therefore the films have to be stable, wear resistant with good adherence to the substrate materials and they have to be resistant against mechanical damage. [..]

Abstract:
The need for decision-making is related to management, constituting the substance thereof. Management means the wilful, purposeful influencing of a certain process, phenomenon or situation in order to achieve the required outcome or objective.Therefore, we make decisions in the case of a deviation from the required status and if the achievement of the objective is at risk, or when we get into a situation when the objective can be achieved in several different ways.

Abstract:
Monitoring the mechanical properties changes is very important to assure structural integrity of NPP components, especially within the context of their operational life extension. Determination of current mechanical properties of several structural materials of NPP components, especially reactor internals, is not possible using the standard testing methods, in connection with the material volume necessary for the testing.

Abstract:
National logistics systems can create a single integrated economy, therefore the problem of choosing locations and connecting logistics centres to the network should be one of the most important planning tasks in the area of spatial development. For research purposes, research was carried out in which 150 students of Logistics from 2nd year of study, formulated cognitive maps for the location of logistics centers with a network of links.

Abstract:
In this work, the dynamic material modelling (DMM) is employed to identify the hot working window that is suitable for hot processing of Duplex stainless steel 2205 (DSS). The Gleeble 1500 thermo-mechanical simulator was used to conduct the investigation, where several hot compression tests were conducted at a temperature range of 850 - 1050 °C and strain rates of 0.001s-1 - 5s-1.
