In the introductory part we give definitions and relationships to determine the reliability and probability of failure of technical systems. After that, the analysis and calculation of reliability, we proposed method, based on the construction of tree failure in the form of logical structure. The second part was performed to verify the model set on...

Spindle is one of the most important member in turning machines, so that its precision determines the dimensional tolerances of machined parts. In this paper, the spindle’s response to standard input parameters has been analyzed via Finite Element Method (FEM).From this point of view, the spindle of LZ330VS turning type machine is modeled wit...

The co-deposition of silver with less noble metals results at low current densities in pure silver coatings or solid solutions of these metals in silver. At high current densities, after saturation of the silver lattice with the alloying metal a new richer in this element phase is formed and heterogeneous coatings are obtained. The spontaneous depo...

A fluid bed dryer with inert particles represents a very attractive alternative to other drying technologies according to the main efficiency criteria, i.e. specific water evaporation rate, specific heat consumption and specific air consumption. A high drying efficiency results from the large contact area and from the large temperature difference b...

Reliable and rapid identification of phyto-pathogens causing plant diseases is playing an important role in their control strategies. The available methods for identification of fungi are time consuming and not always very specific. MALDI-TOF and Fourier-transform infrared (FTIR) microscopy are proved to be comprehensive and sensitive analytical me...

Supercritical fluid extraction (SFE) is an efficient extraction technique for the separation of various organic compounds from herbs, or more generally, from plant materials. As cultivate plant (plant from plantation) Helichrysum italicum from municipality Novi Grad was used in this research. The influence of pressure on total extract yield at flow...

The samples of rolled copper were mechanically and electrochemically polished in suitable electrolytes for electrochemical polishing. These substrate surfaces that had been prepared in advance, served as the basis for depositing of copper layers from two baths, namely, from the basic electrolyte(OR) with the following composition: 240 g/dm3 Cu...

Calcium hydroxyapatite (CHA) has been synthesized biomimetically using simulated body fluid (SBF) alone and in combination with Fetal Calf Serum (FCS) and Eagle’s Minimum Essential Medium (EMEM). Chemical composition of the used SBF is like composition of human plasma, with small differencies in some ions concentrations, and pH value was adju...
