Opis:
In this paper, a method for the determination of the relative and mass exhalation rates is presented. For the measurement of radon content in an emanation chamber, an ?/ß liquid scintillation counter was applied. The method was preliminarily tested on the following samples: (1) samples of uranium tailing piles in the Kowary region, (2) samples obtained by mixing of the mentioned waste with various materials such as cement, gypsum and anhydrite and (3) samples of some building materials.

Opis:
Within the framework of the project for design and optimization of the Remotely Operated Vehicle (ROV), research on its propulsion has been carried out. The entire project was supported by CFD and FEM calculations taking into account the characteristics of the underwater vehicle. One of the tasks was to optimize the semi-open duct for horizontal propellers, which provided propulsion and controllability in horizontal plane. In order to create a measurable model of this task it was necessary to analyze numerical methodology of propeller design, along with the structure of a propellers with nozzles and contra-rotating propellers. It was confronted with theoretical solutions which included running of the analyzed propeller near an underwater vehicle. Also preliminary qualitative analyses of a simplified system with contra-rotating propellers and a semi-open duct were carried out. The obtained results enabled to make a decision about the ROVs duct form. The rapid prototyping SLS (Selective Laser Sintering) method was used to fabricate a physical model of the propeller. As a consequence of this, it was necessary to verify the FEM model of the propeller, which based on the load obtained from the CFD model. The article contains characteristics of the examined ROV, a theoretical basis of propeller design for the analyzed cases, and the results of CFD and FEM simulations.

Opis:
Introduction. A factor that conditions the perception of the quality of life (QoL) is having a social network and relationships within it. The quality of life of seniors is assumed to be at a higher level if they are surrounded by those close to them in comparison to those living alone. The aim of the study was to assess differences in the quality of life of elderly rural residents depending on their family status. Materials and method. Due to the random and mixed selection of respondents, the study comprised a group of 588 representatives living in rural areas of Eastern Poland. The differentiated criterion of the groups of senior respondents was their family situation: living with a family or living alone. Assessment of the quality of life was conducted by means of the WHOQoL-bref questionnaire. The Mann-Whitney tests and Kruskal-Wallis tests were used to carry out statistical analysis of the data. Results. The respondents who lived with their families differed statistically to a significant extent (p<0.005) from those who lived alone. The former gave a better assessment of the majority of the QoL domains: physical, psychological and social. Obtaining higher mean values for the environmental domain among the respondents living alone (M=14.31) seemed to be an atypical and interesting phenomenon because seniors living with their relatives usually assessed that dimension better than those living alone. Conclusions. The family situation of seniors affected the level of quality of life. Living with their relatives may be expected to be favourable for seniors because it translates into better performance in physical, psychological and social domains. Loneliness, which frequently accompanies old age, leads to the deterioration of the quality of life.
