Theoretical support of modern issues related to laser techniques, applications of coherent radiation and modern technologies
Modern problems of the Earth’s population are increasing in the areas related to the basic concepts of survival of living beings, but also with opposite views, if parallels are made between energy and ecology. Many new technologies are searching for their way towards development and must be viewed from several points of view. In this paper, t...

Effect of welded joint imperfection on the load-carrying capacity of pipe elbows subjected to in – plane bending moment
The defects in pipe elbows can, depending on their size and position, affect the integrity and safe service, as well as deformation ability of the piping systems in exploitation. Incompletely filled groove, which is the type of defect examined here, was observed by ultrasonic measurement on the pipeline in the regulation system of the hydro power p...

Determination of the microplastic particle release by tea bags during brewing
The presence of microscopic particles of plastic (MP) in food is currently an urgent problem in the modern food industry and one of the main issues of food safety. However, there are no clear methods for the determination of such particles, nor methods for cleaning food products from them. In the present work, for the first time, the method of Dyna...

3D model of a Monolithic Honeycomb Adsorber for Electric Swing Adsorption for Carbon Dioxide Capture
The goal of this work was to develop a 3D model of Electric Swing Adsorption pro- cess for carbon dioxide capture from effluent gasses from power plants. Detailed 3D model of the composite honeycomb monolithic adsorber was developed for a sin- gle monolith channel and can be used to simulate and represent different physical properties: velocity, co...

Cloud Point Extraction as a Method for Preconcentration of Metal Ions
Cloud point extraction (CPE) is an attractive technique that reduces solvent con- sumption and exposure, disposal costs, and process time. This method has an im- portant practical application and is used to separate and concentrate the analyte as a step before its determination, and after the formation of a poorly water-soluble complex. Use of noni...

Quality testing of industrially produced essential oil of white pine (Pinus sylvestris L.) from the Republic of Srpska
The quality of the essential oil obtained from white pine wood greenery from the territory of the Republic of Srpska was analyzed by examining the chemical composi- tion and antimicrobial activity of samples produced by the hydro-distillation process in industrial production conditions. The chemical composition of the essential oil was analyzed by ...

Simulation of a single-stage evaporator system integrated with a mechanical vapor compressor for concentrating the electrolytic system KNO3 – H2O
A simulation of a single-stage evaporator system integrated with a mechanical com- pressor for a case study (concentrating the electrolytic system KNO3 – H2O) was performed. A mathematical model of the subsystem of a single-stage evaporator, a mechanical compressor, and superheated steam seeding is presented. Microsoft Excel with VBA (Visual ...
