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)
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 presented in this paper deals with application of the short time Fourier transform (STFT) in processing the acoustic emission (AE) pulses generated by six basic forms of partial discharges (PDs) that can occur in insulation systems of power appliances. The paper presents the time-frequency analysis results of the AE pulses generated by(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)
Results of measurements of optical radiation emitted by partial and complete electrical discharges occurring on a bushing insulator model placed in air are presented in the article. Registration was performed using a spectrophotometer, enabling for measurement of optical radiation in the range from 270 to 1700 nm. Detailed characteristics of(More)
The paper presents the results of vibroacoustic investigations and the measurements of the acoustic pressure level (noise) of a transformer model. The measurements were taken at a full transformer load in two operation conditions: at a producer packeted core and at unpacketed core. Unpacketing consisted in loosing the screws pressing the particular core(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)
