Andrzej Zaki’s excavations in the Carpathian mountains, the Alps and the Andes are relatively well-known, however not many heard about his planned excavations in the Himalayas and in the Tibetan Plateau area. This paper is devoted to Andrzej Zaki’s preparations of the expedition, which was Professor’s another project regarding mountain archaeology. The expedition to the Himalayas and to the Tibetan Plateau planned for the end of the ’80s and the beginning of ’90s had been preceded by careful research on the history of human settlement in this area. The research was focused not only on written sources but it also included close contacts with the Office of Dalai Lama XIV living in Dharamsala. Polish Himalayan climber, Wanda Rutkiewicz also played a significant role in the project. The aim of the planned archaeological excavations near the chosen Buddhist monasteries was focused on the creation of a more precise chronology of antiques found during precedent excavations.

The flow of the investigated fluid in a measuring system of a rheometer – a capillary or a slit between rotating parts – may be disturbed by anisotropic behavior of the fluid near the wall. This phenomenon, so-called wall slip, often takes place in concentrated suspensions and solutions of linear polymers and introduces experimental errors to measurement results. There are methods of correction of these errors in the case of capillary and coaxial cylinders measuring systems. In the cone and plate system the correction seems to be more difficult because the width of the gap between cone and plate changes along the radius and thus the influence of the wall slip on the shear stress varies along the radius in an unpredictable and complicated manner. This dependency of the shear stress on the distance from the axis underlies the presented method of correction of experimental results obtained in the cone and plate system. The method requires several series of measurements of shear stress vs. shear rate performed using one measuring set, at various degrees of filling the gap.

Understanding and measuring mental well-being among adolescents has recently become a priority. The validity and reliability study of the 7-item short version of the Warwick Edinburgh Mental Well-Being Scale (SWEMWBS) has not been examined in Turkish adolescents. Therefore, this study aims to adapt the 7-item Warwick Edinburgh Mental Well-Being Scale to Turkish and examine the relationships between loneliness, emotional flexibility, resilience, and mental well-being. The data were collected by convenience sampling method from 820 adolescents aged 14-18 from 73 city of Turkey. During the adaptation process of SWEMWBS, confirmatory factor analysis, concurrent validity, and reliability analysis were performed. The findings confirmed the one dimensionality of the 7-item scale on the Turkish adolescent sample. In addition, a significant positive relationship was found between mental well-being and emotional flexibility and resilience. However, there was a significant negative correlation between mental well-being and loneliness. The results showed that the Turkish version of SWEMWBS had strong psychometric properties in adolescents.

The paper reports the results of a physical modelling study of the production of a hypereutectic aluminium alloy to be used for making an alloy vapour source for operation in the magnetron. Within the study, targets from a hypereutectic aluminium-silicon alloy were made in laboratory conditions. Thus obtained material was subjected to heat treatment, porosity analysis, and the assessment of the microstructure and fitness for being used in the magnetron. The process of melting the hypereutectic Al-Si alloy was carried out at the Department of Foundry of the Czestochowa University of Technology. The investigation into the production of the alloy vapour source for the synthesis of the dielectric material from the hypereutectic aluminium alloy has confirmed.

This paper analyses the heat treatment of the hot-dip zinc coating deposited on both cast iron and steel. The aim of research is to increase coating hardness and wear resistance without decreasing its anticorrosion properties. Hot-dip zinc coating was deposited in industrial conditions (acc. PN-EN ISO 10684) on disc shape samples and bolts M12x60. The achieved results were assessed on the basis of microscopic observation (with the use of an optical and scanning microscope), EDS (point and linear) analysis and micro-hardness measurements. It was discovered that the heat treatment of zinc coating results in an increase in hardness which is caused by the corresponding changes in microstructure.
