INTRODUCTION Medical students' attitude towards euthanasia is a very important ethical problem because they may grapple with this question as future doctors. The aim of the study was to compare the attitude to euthanasia in the group of first year medical students from Pomeranian Medical University in Szczecin, Ernst-Moritz-Arndt University Greifswald(More)
INTRODUCTION Ankle fractures are among the most common musculoskeletal injures. These fractures occur with an overall age- and sex-adjusted incidence rate around 180 per 100 000 person-years. The most frequent mechanism is considered to be supination-external rotation (60 to 80% of all ankle fractures) consisting of pathologic external rotation of the foot(More)
In the paper some results of experimental works on streaming electrification in swinging cylinder system have been shown. Mineral transformer oil is used as dielectric liquid in which charge generation occurs. A shuttle system with swinging cylinder is proposed to study the flow electrification phenomena. Designed system allows for modulation of liquid flow(More)
The subject matter of this paper refers to the improvement of the acoustic emission (AE) method when used for detection, measurement and location of electrical discharges in air insulation systems of power appliances. The detailed subject matter refers to the issues connected with the application of modern methods of digital processing of signals obtained(More)
The subject matter of this paper refers to the correct recognition of the acoustic emission (AE) signals generated by basic partial discharge forms (PDs). The paper presents research results of the application of unidirectional artificial neural networks (ANN) for recognizing basic PD forms that can occur in paper-oil insulation impaired by aging processes.(More)
The subject matter of this paper is connected with determining the application possibilities of the optical spectrophotometry method in diagnostics of insulation systems of apparatuses and electrical appliances operating in an electrical power system. The paper will present the measurements and analysis results of optical signals generated in spark-gaps(More)
The subject matter of this paper refers to the improvement of the use of the acoustic emission (AE) method in diagnostics of paper-oil insulation systems of power appliances. The paper will present modern processing methods of the AE signals registered during diagnostic measurements of power transformers. First of all, the results of the time-frequency(More)
This paper concerns improvement of evaluation methods of partial discharge (PD), which may occur in the power transformer insulation systems. This particular study regards the next stage of research works, which aim to determine the energy share of particular physical phenomena accompanying generation of PD. The performed works were connected to comparative(More)
