Teoretyczne podstawy badań nad wydarzeniami medialnymi
The aim of this paper is to present and discuss theoretical background for media events studies that have been conducted since the 1980s. The paper collects all major perspectives and studies in order to provide a complete picture of a theoretical approach to research on the media events. First, the paper reviews concepts developed by E. Durkheim and so called neodurkheimists, including E. Rothenbuhler and W. Shils. These concepts provided the background and led to a deeper understanding and an explanation of symbolic dimensions of social relations, contemporary ceremonies, rituals (including political ones), and the role of the media in creating the social and political reality. One of Durkheim’s fundamental concepts distinguishing sacrum and profanum provided the background for a concept of media events developed by E. Katz and D. Dayan. While the classic version of this concept included just three main types of the media events (conquest, coronation, and contest), the more recent one is extended and includes six types. Based on the empirical studies conducted by T. Liebes, E. Rothenbuhler, and G. Weimann (to name just some of the scholars), three more types have been added, namely: coercion, disaster, and war. They share a disruptive character (instead if integrative one) and they describe relations between the organizers of an event, media organizations, and the audience in a different manner than the classic version of the concept. For this reason, the idea of including them into a classic concept seems to be criticized by some scholars, including E. Rothenbuhler. Instead, he proposes that a concept of ritual communication as a broader frame for studies on media events should be used
Modified and unmodified zinc oxide as coagent in elastomer compounds
The aim of this work was to study the activity of unmodifi ed and modifi ed ZnO in the peroxide crosslinking of hydrogenated acrylonitrile-butadiene elastomer (HNBR) and ethylene-propylene copolymer (EPM). In the first step, zinc oxide was obtained by emulsion precipitation. Maleic acid was introduced onto the surface of ZnO using
an in situ method. The unmodifi ed and modifi ed zinc oxide was characterized using dispersive and morphological analysis, BET surface area analysis, and elemental, spectroscopic and thermal analysis. In the second stage of the research, the ZnO/MA systems were incorporated into the structure of elastomer compounds improving the
kinetic and mechanical properties of vulcanizates. The proposed modifi cation method had a favorable effect on the physicochemical properties of the zinc oxide and on the kinetic and mechanical properties of the vulcanizates. This study demonstrated that modifi cation of zinc oxide by maleic acid is a promising technique

Out-of-hospital cardiac arrest: Do we have to perform coronary angiography?
Out-of-hospital cardiac arrest (OHCA) remains a leading cause of global mortality, while survivors are burdened with long-term neurological and cardiovascular complications. OHCA management at the hospital level remains challenging, due to heterogeneity of OHCA presentation, the critical status of OHCA patients reaching the return of spontaneous circulation (ROSC), and the demands of post ROSC treatment. The validity and optimal timing for coronary angiography is one important, yet not fully defined, component of OHCA management. Guidelines state clear recommendations for coronary angiography in OHCA patients with shockable rhythms, cardiogenic shock, or in patients with ST-segment elevation observed in electrocardiography after ROSC. However, there is no established consensus on the angiographic management in other clinical settings. While coronary angiography may accelerate the diagnostic and therapeutic process (provided OHCA was a consequence of coronary artery disease), it might come at the cost of impaired post-resuscitation care quality due to postponing of intensive care management. The aim of the current statement paper is to discuss clinical strategies for the management of OHCA including the stratification to invasive procedures and the rationale behind the risk-benefit ratio of coronary angiography, especially with patients in critical condition
Good practice of making art and culture accessible to the deaf and hard of hearing, on the example of the Deafland exhibition at the Silesian Museum in Katowice
The issue of the accessibility of culture and art for deaf and hard of hearing people is the topic of the implementation doctoral dissertation conducted by the author of the article under the supervision of dr hab. prof. University of Lodz Aneta Pawłowska as part of the Doctoral School of Humanities at the University of Lodz and the Association Social Support "Ja-Ty-My" in Lodz entitled: The problem of accessibility of information in public institutions and social economy entities in the field of culture and art for people with hearing loss and disabilities in Poland. Recommendations and standards.
The article is an attempt to look from the point of view of a researcher - a deaf person - insider, at the issue of the broadly understood accessibility and significance of the Deafland (Głusza) exhibition at the Silesian Museum in Katowice (a breakthrough in Poland in terms of the subject matter and the model of available technical solutions for people with special needs)
Characterization of amino-, epoxy- and carbonyl-functionalized halloysite and its application in the immobilization of aminoacylase from Aspergillus melleus
Functionalized halloysite was used as a support for the immobilization of an enzyme. The surface of halloysite was modified with amino (–NH), epoxy (–C(O)C) and carbonyl (–C=O) groups. Both unmodified and modified forms of the support underwent a comprehensive physicochemical and structural evaluation, including morphological, structural, thermogravimetric and spectroscopic analysis. Aminoacylase from Aspergillus melleus was used as the enzyme in the immobilization process. The process of immobilization by adsorption was performed for 1, 6 and 24 h using different concentrations of enzyme solution (0.5, 1 and 3 mg/cm3). The quantity of aminoacylase loaded onto the support was calculated by the Bradford method. Free and immobilized aminoacylase were used to catalyze the deacetylation of N-acetyl-L-methionine. Additionally, the thermal and chemical stability of the obtained biocatalytic systems were evaluated, as well as the reusability of the immobilized systems. The biocatalytic system with amino groups demonstrated activity above 70% in the pH range 4–9 and 60% in the temperature range 30–70 °C. Aminoacylase immobilized on amino-functionalized halloysite also retains around 50% of its initial activity after five reaction cycles
Zinc Oxide—From Synthesis to Application: A Review
Zinc oxide can be called a multifunctional material thanks to its unique physical and chemical properties. The first part of this paper presents the most important methods of preparation of ZnO divided into metallurgical and chemical methods. The mechanochemical process, controlled precipitation, sol-gel method, solvothermal and hydrothermal method, method using emulsion and microemulsion enviroment and other methods of obtaining zinc oxide were classified as chemical methods. In the next part of this review, the modification methods of ZnO were characterized. The modification with organic (carboxylic acid, silanes) and inroganic (metal oxides) compounds, and polymer matrices were mainly described. Finally, we present possible applications in various branches of industry: rubber, pharmaceutical, cosmetics, textile, electronic and electrotechnology, photocatalysis were introduced. This review provides useful information for specialist dealings with zinc oxide
