In this paper model of a vibrating system of two rotating, stressed to each other and periodically losing contact cylinders is presented. The model is
described by two-degrees-of-freedom Hill's differential equations sys...
According to the European Standard PN-EN 10216-2 two types of the heat treatment could apply to 7CrMoVTiB10-10 – the modern bainitic
boiler steel. The 7CrMoVTiB10-10 steel may have different properties, depending on the...
Betanin and neobetanin (14,15-dehydrogenated betanin), natural betacyanin pigments were subjected to a gentle reduction by 2-methylpyridine
borane. During each reduction reaction, the visible spectra were collected. The...
Simulation of injection molding of polymeric materials is still a series scientific and engineering problem. The quality of the input data is crucial for
computation accuracy. The original, relatively simple tool has bee...
Chemical admixtures, in addition to cement, sand, gravel and water, are a primary component of concrete. High-range water reducers, also known
as superplasticizers, are one of the most important chemical admixtures. The...
Spectral analysis of parametric two degreesof- freedom system
In this paper model of a vibrating system of two rotating, stressed to each other and periodically losing contact cylinders is presented. The model is described by two-degrees-of-freedom Hill's differential equations sys...
The effect of the heat treatment on the 7CrMoVTiB10-10 steel's microstructure and its properties
According to the European Standard PN-EN 10216-2 two types of the heat treatment could apply to 7CrMoVTiB10-10 – the modern bainitic boiler steel. The 7CrMoVTiB10-10 steel may have different properties, depending on the...
Profiles of products generated during betacyanins reduction by 2-methylpyridine borane
Betanin and neobetanin (14,15-dehydrogenated betanin), natural betacyanin pigments were subjected to a gentle reduction by 2-methylpyridine borane. During each reduction reaction, the visible spectra were collected. The...
