The subject of the article is the occurrence of dialectal features in Internet nicknames. The analysis was carried out on the basis of about 2500 nicknames that contained dialectal features. The names were obtained within the years 2012–2015. In the analysis, linguistic areas were indicated in which we may notice the influence of local dialects on that layer of the Internet anthroponymy. The influence of local dialects is visible in the fact that the Internet users reach for traditional folk names as well as name models related to the folk manner of identifying a human being, e.g. Jagatka, Jantecek, Janielka od Genowefy, Cesiek z Tuchowa. Apart from references to folk anthroponymy, the Internet nicknames reflect the influence of local dialect lexis (e.g. gzub, graślok, fusyt), phonetics (janioł, Carownica, łokrutny łoptymista), inflection (Śpisok z Łapsóf, ciupaga łod tater) and word-formation, e.g. (rzemyszek, cwaniuk).

The purpose of the work was to determine the infuence of the bulk density ρz of granules, processing parameters and the density of ski inserts ρw made of expanded polystyrene (EPS) on their damping properties. For this aim liners for ski helmets with 3 different bulk densities were made. Sintering time and sintering pressure were also changed. The percentage damping factor η was determined on the basis of the results obtained in the rebound resilience test. Based on the analysis of the obtained data, it was found that increasing the density of EPS pads ρw increases their damping properties and at the same time contributes to a decrease in elasticity, increase in hardness and brittleness of EPS products.

This paper presents the study of microstructure and properties of 8 mol% yttrium stabilized zirconia coating fabricated by Plasma Spray Physical Vapor Deposition technique on commercial pure titanium. The coating was characterized by X-ray diffraction, high resolution scanning electron microscope, profilometer, nanoindentation and nanomachining tests. The X-ray phase analysis exhibit the tetragonal Zr0.935Y0.065O1.968, TiO and α-Ti phases. The Rietveld refinement technique were indicated the changes of crystal structure of the produced coatings. The characteristic structure of columns were observed in High Resolutions Scanning Electron Microscopy. Moreover, the obtained coating had various development of surfaces, thickness was equal to 3.1(1) µm and roughness 0.40(7) µm. Furthermore, the production coatings did not show microcracks, delamination and crumbing. The performed experiment encourages carried out us to tests for osseointegration.

Thanks to dyeing of polymers, the possibilities of their use are constantly increasing. It is equally important to use additives that will have several functions. A perfect example is titanium dioxide used as an optical brightener and a flame retardant at the same time. Mostly it is used in the form of a powder. However, there are no studies where TiO2 is used as a colourbatch based on the different polymer matrix.
The aim of the work was to investigate the effect of titanium white in the form of colourbatch on the flammability and selected properties of mouldings produced in various processing conditions. Colourbatch based on PS matrix, was used in the research. The variable processing parameters were: injection temperature Tw, volume flow rate Vw, residence time and the addition of a colourbatch. On the basis of the measurements, it was found that the processing conditions and the addition of the colourbatch have low effect on the hardness of the mouldings, which was in the range from 75.59o Sh D (Shore type D) to 81.95o Sh D. It was also noted that the addition of colourbatch with TiO2 and increasing injection temperature reduces impact strength even by several dozen percent. Moreover, it was found that use of TiO2 causes a delay in the ignitability of the samples in selected cases. It is difficult to determine whether the variable processing conditions or the addition of TiO2 on the PS matrix have a greater impact on the ignitability of the moulded parts.

Optical low-coherence interferometry is one of the most rapidly advancing measurement techniques. This technique is capable of performing non-contact and non-destructive measurement and can be used not only to measure several quantities, such as temperature, pressure, refractive index, but also for investigation of inner structure of a broad range of technical materials. We present theoretical description of low-coherence interferometry and discuss its unique properties. We describe an OCT system developed in our Department for investigation of the structure of technical materials. In order to provide a better insight into the structure of investigated objects, our system was enhanced to include polarization state analysis capability. Measurement results of highly scattering materials e.g. PLZT ceramics and polymer composites are presented. Moreover, we present measurement setups for temperature, displacement and refractive index measurement using low coherence interferometry. Finally, some advanced detection setups, providing unique benefits, such as noise reduction or extended measurement range, are discussed.

Congestion is a significant problem affecting the operational processes of a hospital’s outpatient department (OPD). Congestion especially affects the OPD’s architectural space, due to the increased number of patients. Recently, digital tools have been used in healthcare systems to reduce congestion and help the OPD improve its operational processes; one of these tools is the virtual examination room. However, patients still need to be examined by physicians in the OPD, and digital tools alone cannot solve all the problems that congestion creates. The authors of this paper conducted a study that offers a new way to alleviate congestion in the OPD by combining physical and digital solutions to increase OPD efficiency and optimize its operational processes. The study created an alternative operational plan that adds virtual examination rooms to reduce congestion. This plan allows the OPD to increase the number of physical and virtual examination rooms by almost 110% and increase the number physically and virtually examined patients by 153% each day. The plan also redesigns some architectural spaces at the OPD to enhance the environment and match the hospital’s requirement for authorized bodies.
