DETERMINATION OF DELTA FERRITE IN AUSTENITIC STAINLESS STEELS
Microstructure of an austenitic stainless steels is primarily monophasic, i.e. austenitic. However, the chemical composition of steel can affect on precipitation of a delta ferrite. The presence of the delta ferrite in austenitic stainless steel has a beneficial or detrimental effect on mechanical properties (impact and tensile) as well as on welda...

ANALYSIS AND CONTROL OF TRAFFIC NOISE IMPACT ON THE OBJECTS ALONG THE MAIN CITY HIGHWAY (GGM) ZENICA
Noise is one of the greatest factors that has an affect on damaging our environment. Traffic noise affects mostly the population that has no direct contact with noise sources, and as such, traffic noise presents a very serious social problem. This paper presents traffic noise measurements on locations of the Main City Highway in Zenica. Among other...

GENERAL CONSIDERATIONS OF GROUNDWATER MOVEMENT
Groundwater motion is a specific case of fluid motion in a porous medium and is called filtration. Such movement is encountered in the most diverse fields of technology: in hydrotechnics and land reclamation, in water supply and sewerage, in the exploitation of oil, in foundries (gas filtration through mold material) and the like. Filtration plays ...

DESIGN OF EXPERIMENT AND MATHEMATICAL MODEL OF BENDING STRENGTH OF SOLID WOOD PANEL
The aim of this paper is to present a sufficiently adequate and accurate mathematical model of the breaking force of a solid wood panel. For that purpose, an experiment with thirteen repetitions was designed and done. The input sizes that varied on three levels are the density of the wood and the thickness of the solid wood panel. Since the central...
