    Opis:
    Despite the dominating and expansive role of the Internet, global reports on mass media still find television as the most popular source of information on health. The following paper is an attempt to systematize the knowledge concerning television broadcast dedicated to the subject of health and illness. The authors aimed to identify the benefits and limitations resulting from the use of the audiovisual means to convey information on health; diagnosing potential threats and explaining trends and possibilities of making use of the television to educate and improve health awareness of the viewers. A critical review of 47 papers published in Polish and international scientific journals in years 2010 – 2014 has been performed. They were categorized into 8 following sections: 1) health information in medical television series; 2) subject of health in reality television programmes and medical talk-shows; 3) health in television news programmes; 4) television and the issue of physical activity and nutrition; 5) television and selected stimulants (cigarettes/alcohol); 6) television and information about cancer and other diseases; 7) public service announcements concerning health/PSA; 8) television and health education/ edutainment. In the light of the conducted review, the television presents itself as a promising source of information on the topic of health and illness which, provided one maintains a cautious attitude as well as moderation, influences the level of knowledge of the viewers, identification of simple symptoms and constitutes an important source of education in terms of prevention and avoiding risk behaviours.

    Opis:
    Wstęp. Uzależnienie od wyrobów tytoniowych jest poważnym problemem w skali globalnej. Jest również głównym czynnikiem ryzyka w zakresie chorób układu krążenia, nowotworów czy chorób układu oddechowego. Z badań przeprowadzonych przez WHO wynika, że na świecie z powodu chorób odtytoniowych umiera 6 mln osób, zaś w 2030 liczba ta przekroczy 8 mln. W Polsce pali papierosy 31% obywateli. Niepokoi fakt, iż po produkty tytoniowe coraz częściej sięga nie tylko młodzież szkół średnich, ale również młodzież gimnazjalna oraz ze szkół podstawowych. Zasadne wydaje się zatem poznanie zachowań ryzykownych wśród młodzieży akademickiej w zakresie używania produktów tytoniowych. Cel pracy. Celem pracy była ocena rozpowszechnienia palenia tytoniu wśród studentów pierwszego roku uczelni rzeszowskich. Materiał i metoda. Badaniami objęto ogółem 924 studentów pierwszego roku Uniwersytetu Rzeszowskiego oraz Politechniki Rzeszowskiej, studiujących na kierunkach: medycznym, humanistycznym i ścisłym. Badania przeprowadzono metodą sondażu diagnostycznego z wykorzystaniem techniki ankiety. W opracowaniu statystycznym wykorzystano test niezależności chi-kwadrat. Wyniki. W wyniku przeprowadzonych badań stwierdzono, iż ponad połowa badanej młodzieży akademickiej (67,4%) nie paliła papierosów (kierunek medyczny 71,6%, kierunek ścisły 67,7%, kierunek humanistyczny 66,0%). Okazjonalne palenie deklarowało 14,9% ankietowanych, codzienne 11,9%, kilka razy w tygodniu 3,6% respondentów. Ankietowani studenci za najczęstszą przyczynę palenia produktów tytoniowych podawali spotkania towarzyskie (15,4%) oraz uczucie przyjemności (8,0%). Większość respondentów (84,1%) uważała, iż palenie tytoniu powoduje choroby, zaś palenie w obecności innych osób jest bardzo szkodliwe (79,8%). Badani studenci (78,5%) uznali, iż zakaz palenia w miejscach publicznych jest słuszny. Wnioski. Niniejsza praca ukazała, iż palenie produktów tytoniowych staje się coraz mniej atrakcyjne w kręgach studenckich. Ankietowana młodzież pali papierosy najczęściej podczas spotkań towarzyskich, pomimo twierdzenia, że palenie w obecności innych osób jest bardzo szkodliwe.
    Introduction. Addiction to tobacco products is a serious global problem. It is also a main risk factor of cardiovascular diseases, cancer, or respiratory diseases. Studies conducted by the WHO show that 6 million people worldwide die due to tobacco-related diseases, and in 2030 this number will exceed 8 million. In Poland, 31% of citizens are smokers. It is an alarming fact that increasingly more frequently not only secondary school adolescents, but also those attending junior high and primary schools, reach for cigarettes. Therefore, it seems justifiable to recognize risky behaviours in the area of the use of tobacco products among university students. Aim of research. The aim of this study was to evaluate the prevalence of smoking among first year students of Rzeszow universities. Material and methods. The study covered a total of 942 first year students from the University of Rzeszów and Rzeszów University of Technology, studying the following disciplines: medical, humanities and exact sciences. The study was performed by the method of a diagnostic survey using a questionnaire technique. Statistical analysis was performed by chi-square test for independence. Findings. The results of the study showed that more than a half of the students examined (67.4%) did not smoke cigarettes (71.6% students of medical disciplines, 67.7% from exact sciences and 66.0% students of humanistic disciplines). Occasional smoking was declared by 14.9% of respondents: 11.9% – daily, several times a week – 3.6%. The students in the survey indicated as the most common cause of smoking tobacco products: socializing (15.4%), and the feeling of pleasure (8.0%). The majority of respondents (84.1%) believed that smoking causes diseases and, in the presence of others, is very harmful (79.8%). The students (78.5%) agreed that prohibition of smoking in public places is right. Conclusions. The study showed that smoking tobacco products is becoming increasingly less attractive among students. The young people in the survey most often smoke cigarettes during social gatherings, despite their declarations that smoking in the presence of others is very harmful.

    Opis:
    Application of metal coatings and the carburized layer are widely known and readily used for various elements, depending on the application. Metal coatings based on chromium are used in order to increase resistance to wear, corrosion and erosion. The coatings applied by different methods have a significant drawback - they are not well related with the substratum, so there is a risk of cracking or flaking. Any discrepancies and flaws disqualify such a way as to protect the surface. Carburizing processes will be carried out, primarily in order to increase the hardness of the surface layer while maintaining a ductile core of the object. It is likely that the combination of these treatments will provide to increase the hardness of the material. The behavior of the proper order to create hybrid layer ensures the continuity of the resulting layer and its good connection with the steel. The paper presents a hybrid layer consisting of the deposited chrome and PVD in the next stage of low pressure carburizing. Conducted process allows chromium diffusion into the material, the enrichment of the steel and to ensure the continuity of the layer.

    Opis:
    The bead blasting process is widespread in both the automotive and aerospace industry and is performed in order to improve the fatigue strength of various components. Bead blasting is a cold plastic forming process during which the surface of the material processed is hit by small, hard particles consisting of steel pellets, bearing balls or glass beads. It increases the hardness of the outer layer and establishes compression stresses inside it, which is why this processing is often used to improve fatigue strength. Contrary to other peening methods, bead blasting does not result in a reduction in the height of the processed surface’s unevenness in most cases. Shot peening changes the residual tensile stresses into residual compression stresses, thanks to which, the lifetime of the parts processed is extended and their carrying capacity is increased. The double shot peening process proposed by the authors consists in a two-stage bead blasting process. The first stage consists in blasting with round cast steel pellets, pellets cut from wire or cast iron pellets. During the second stage the same samples underwent glass bead blasting. The tests conducted on the RSA-501 aluminum alloy indicate that as a result of the processing medium’s impact in the form of glass beads or pellets of different diameter and shape, a permanent plastic deformation of the material surface occurs. On the basis of the obtained results it is possible to infer that the choice of parameters of both conventional shot peening and the double shot peening determine the impact thereof on the material’s mechanical properties. Thanks to the application of the double shot peening process there is a noticeable decrease in value of the Ra parameter, by about 40% on average. When analyzing the compressive stress results it is possible to state that after the first blasting process the value of stress was increasing when moving deeply into the sample from its surface, while after the glass bead blasting the value of compressive stress was significantly higher already near the surface. Double shot peening results in an increase in the value of compressive stresses by 40-50% when compared to conventional blasting.

    Opis:
    An improvement in fatigue strength is one of the main factors enabling the use of high-durability Al-Mg-Mn-Sc-Zr alloys in functional components of mobile robots. As part of this study, a computer simulation was carried out using ANSYS LS-DYNA software that involved the hybridization of high pressure torsion (HPT) and shot peening (SP) forming processes. The numerical analysis was aimed at determining residual stresses and strains that affect the durability and stress characteristics of the analyzed Al alloy. Results of the study indicate that tensile stresses of σ = 300 MPa generated as a result of HPT are transformed into a beneficial stress of σ = 25 MPa resulting from plastic strains caused by SP surface treatment.

    Opis:
    Conventional shot peening (SP) is cheap surface treatment widely used to enhance fatigue life of mechanical components [3,4]. Basically, it is shooting small particles (shots) on the surface of the sample. However, the process itself is so complex that a lot of companies are not able to optimally employ it due to the amount of parameters that must be controlled all at the same time. The duplex process consists in two stages of shot-peening treatment. The first one consist of shot-peening with spherical cast steel shots or cut wire shots. During the second stage the samples processed in stage one were subject to shot-peening with glass beads. In this work, RSA-501 aluminium alloy was shot peened using shots of different material and diameter and tested using a measurement of residual stresses and surface roughness. Tests and studies conducted so far on RSA-501 aluminium alloy demonstrate that bombardment by a treatment medium in the form of glass beads or shots of various shapes and diameters induces permanent plastic deformation of the surface layer. The roughness achieved after the shot-peening process was determined for each treatment medium. The largest value of Ra parameter was achieved for cut wire shots and this result is consistent with the above-mentioned theoretical knowledge. This medium is the most aggressive one to the surface being treated primarily due to the sharp edges of shots. The duplex process was successful in obtaining higher values of compressive stresses in surface layer than values achievable in conventional single-stage shot peening process.

    Purpose: This study presents the residual stress analysis for the twist extrusion (TE) process after the experiment and numerical simulation and the analysis of the crystallographic texture changes and changes in hardness before and after the TE process for an RSA-501 aluminium alloy (Al; Mg5%; Mn1.5%; Sc0.8%; Zr0.4%). Design/methodology/approach: Crystallographic textures were obtained with the PANAlytical Empyrean X-ray diffractometer. The stresses were measured by applying the X-ray method with the use of using the PROTO iXRD diffractometer. Findings: The use of severe plastic deformation processes in the mass of the material leads to a significant change difference in the stress distribution in the workpiece and a change in texture compared to the reference material. The stress distribution in the sample cross-section and stress values varied and depended on the stage of the twisting process to which the surface was subjected. The highest stress (about 600 MPa) appears at the peaks of the front surface when exiting the twist area die TE. Higher stress values at the edges of the specimen are caused by friction (deformation) of the material against the die surface. The TE process strengthened – the highest crystallographic texture background level was 49%. Practical implications: The conducted tests and the obtained results allow the determination of the process parameters and critical areas of the sample by carrying out a numerical simulation. Originality/value: Microhardness increases due to the TE process and the largest values were observed at the edges. This phenomenon is confirmed by the numerical simulation results presented in this paper.
