This paper describes the design of a 3D printed spectrometer for the visible and near-infrared region of the electromagnetic spectrum of light. The device has a resolution of about 2 nm and forms only one part of the whole, which still consists of a suitable light source, sample container or cuvette, and accompanying optical cables. The spectrum of...

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...

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...

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 ...
