Opis:: Praca dotyczy dezintegracji przy użyciu ultradźwięków cząstek zawartych w zawiesinie w tzw. procesie sonikacji. Efekty praktycznego korzystania z sonikacji w procesach dezintegracji przedstawiono na przykładach dyspersji aglomeratów Aerosilu i dezintegracji komórek drożdży. Porównanie danych eksperymentalnych z wynikami symulacji wymagało przeprowadzenia obliczeń CFD. Przedstawione rezultaty potwierdzają użyteczność modelowania dla prawidłowego projektowania procesów dyspersji metodą sonikacji.
Ultrasonic cell and agglomerate disruption is investigated experimentally and numerically. The CFD modeling is applied to predict spatial distribution of acoustic pressure in the system equipped with ultrasonic disintegrator. Examples for disintegration by ultrasounds are presented for yeast cells and silica agglomerates. Comparison of model predictions with experimental data shows that numerical methods are helpful for interpretation and design of sonication processes.

Opis:: One of the most important issue regarding scheduling problem is production uncertainty. From the standpoint of real-world scheduling problem, it is necessary to find solution of building the schedule which can be insensitive to production disruptions such as machine breakdowns, incorrectly estimated time interval of machines maintenance, absence of workers, unavailability of materials or tooling, production defects, variable processing times, etc. This research study is conducted to answer the question: how the researchers cope with the problem of production uncertainty taking into account the scheduling problem? Our investigation focuses on approaches developed for scheduling with production uncertainty consideration. Among these approaches the most popular ones are: reactive scheduling, proactive scheduling, predictive scheduling and robust predictive-reactive approaches. A brief explanation of individual approaches are presented. Further, models of uncertainty used in scheduling approaches are highlighted.

Opis:: Political, economic, civilizational and social changes in the last few decades have led to a global anomie, and in this reality it was possible for the ideology of disruption to arise. If society were not immersed in the process of decomposing existing normative regulations, such marketing of quasirevolutionary ideas would be doomed to failure. Undermining the sense of normative regulation of goals and replacing them with new ones (surrounded by a false myth of improving the world) is an example of anomie used to maximize profits (not only in the financial sense). Simultaneously, two new mechanisms of social control have been developed and consolidated – control through emotions and control through the creation of illusions. This text is a preliminary attempt to analyse the above phenomena and processes.
Zmiany polityczne, ekonomiczne, cywilizacyjne i społeczne ostatnich kilkudziesięciu lat doprowadziły do globalnego rozregulowania, w której to rzeczywistości mogła zaistnieć ideologia dezorganizacji. W społeczeństwie niepogrążonym w procesie dekompozycji dotychczasowych regulacji normatywnych (anomia) ten typ marketingowych quasi-rewolucyjnych idei skazany byłyby na porażkę. Podważanie sensu normatywnych regulacji celów i zastępowanie ich nowymi (otoczonymi fałszywym mitem udoskonalania świata), to przykład anomii wykorzystywanej do maksymalizacji zysku (nie tylko w sensie finansowym). Równolegle wypracowane zostały i uległy utrwaleniu dwa nowe mechanizmy kontroli społecznej – kontrola przez emocje i kontrola przez tworzenie iluzji. Niniejszy tekst stanowi wstępną próbę analizy wskazanych powyżej zjawisk i procesów.

Opis:: The COVID-19 pandemic and especially the lockdowns coming with it have been a disruptive event also for food consumption. In order to study the impact of the pandemic on eating habits, self-reported changes in food-related behaviours were investigated in ten European countries by means of an online survey. A latent class cluster analysis distinguished five clusters and showed that different types of consumers can be distinguished based on how they react to the pandemic as regards their eating habits. While food-related behaviours were resilient for 60% of the sample, another 35% reported more enjoyment in cooking and eating, more time in the kitchen and more family meals. Among those, a slight majority also showed signs of more mindful eating, as indicated by more deliberate choices and increased consumption of healthy food, whereas a slight minority reported more consumption of indulgence food. Only 5% indicated less involvement with food. As the COVID-19 pandemic is a disruptive event, some of these changes may have habit-breaking properties and open up new opportunities and challenges for food policy and food industry.

Opis:: RESEARCH OBJECTIVE: This paper aims to summarize and discuss key findings in the literature around the concept of disruption or disruptive innovation and how the ad hoc academic knowledge evolved in the recent couple of decades. THE RESEARCH PROBLEM AND METHODS: The research method is based on historical and critical literature review. Hence, this paper discusses other scholars’ research and findings around the topic of disruption innovation. THE PROCESS OF ARGUMENTATION: This paper starts with a summary of Christensen’s disruption theory (1997) followed by some important clarifications of ad hoc definitions. Then it inspects some of this theory weaknesses highlighted in the literature before investigating the main recent developments in the last couple of decades and the related research venues. RESEARCH RESULTS: Despite the positive efforts made by many scholars to reconcile Christensen’s disruption theory (1997) with the reality of the market and empirical data and to clarify the concept of disruption and its numerous implications and frameworks, some fuzziness and many gaps are still persisting in the extant literature. Namely, a normalized and exhaustive disruption framework seems to be missing hitherto. CONCLUSIONS, INNOVATIONS, AND RECOMMENDATIONS: This paper provides a refined picture of the academic discussion around disruption innovation, and is hence a useful starting point for researchers interested in topics related to “innovation management” who would like to investigate further avenues of research directly or indirectly linked to disruption.

Opis:: This article explores the relation between cinema and philosophy through the lens of interest shown by some filmmakers in the lives and works of philosophers. It begins by delving into contemporary perspectives on the relationship between philosophy and cinema. In order to assess how the constitutive dissimilarity of the two terms and the ways in which they can be brought together are at the origin of speculative short circuits and experiences of wonder, it brings together the works of thinkers – Cavell, Benjamin, and Kracauer; and filmmakers Rossellini, Montaldo, Keaton, and Jarman. Reflecting on the aesthetic and cultural impact of cinema is all the more important given the current omnipresence of images and prosthetic technologies that, with their incessant solicitations, threaten the processes of apprehension, learning, and conveying of knowledge. Thinking and perceiving differently thus becomes an essential function of cinema, one keenly performed in Safaa Fathy’s Derrida’s Elsewhere, analyzed in the last two sections.

Opis:: Through myths that pattern and repeat we figure the world to ourselves. The desire to be done with myth, to surpass mythic thinking in favor of a “more” rational way of thinking, is but one way of perpetrating violence in the guise of similitude. The rejection of muthos by logos is itself a form of violence, with significant ramifications. The following analysis will explore the work of Luce Irigaray’s Speculum of the Other Woman, and Jean-Luc Nancy’s Inoperative Community, focusing on the ways in which myth becomes mythology, and the inescapable question of violence that attends this operation. This paper, although touching upon the matter, is not an attempt to answer the larger question of what myth is. The scope of this analysis is constrained to a discussion of both Nancy and Irigaray’s understanding of myth as foundational, as well as interrogating the nature of the violence of representation. I will briefly touch upon the long and elaborate conversation surrounding the muthos–logos divide.

Opis:: Impulsowe zakłócenia generowane podczas wyładowania atmosferycznego są przyczyną zakłócenia procesu eksploatacji elektronicznych systemów bezpieczeństwa (ESB). Prądy i napięcia występujące podczas wyładowania indukują w liniach dozorowych zakłócenia. Odpowiednia organizacja ESB na obszarze kolejowym i urządzenia przepięciowe to zabezpieczenie przed zakłóceniami. Występowanie zakłóceń podczas użytkowania systemu wymaga stosowania innego algorytmu do wyznaczania wskaźników oceny bezpieczeństwa.
This paper presents the results of electromagnetic interference generated during lightning on the process of operation of security systems - ESB. Electric and magnetic fields which are generated during atmospheric discharge may have very high values near to the main channel of lighting discharge (1). The impulse of the electromagnetic field that occurs during this phenomenon, induces electromagnetic interferences (voltages and currents) having very high values (Fig. 1) also in power ground lines and in transmission buses of the ESB system. The pulse amplitudes of surge signals (main and return discharge) may affect operation of the ESB or cause total or partial damage. The ESB may be present at the set of different exploiting states, which result from “normal” or electromagnetic interferences exploitation process. The proper usage of the ESB in enormous railway is an absolutely complicated technical issue, where, in addition to the “normal” exploitation specified in technical standards, there are issues related to the problem of ensuring electromagnetic compatibility (3). The occurrence of electromagnetic interference with high power levels can lead to a catastrophic failure in the system of the ESS. The research allowed determining the effect of the pulse electromagnetic field generated during lightning on the test systems.

Opis:: This article concerns the increasing complexity and variability of the business environment and the challenges faced by enterprises that operate within supply chains to properly identify and anticipate disruptions and adequately respond to them (i.e., the ability to resist and rebuild). This article aims to identify and evaluate the importance of the main factors that determine supply chains’ adaptability in the modern economy. A review of the literature on the subject, and the results of a survey conducted in the third quarter of 2022 among entities from the transport forwarding logistics (TFL) industry, diagnose the determinants of the adaptability of supply chains that operate when there are disruptions. They indicate the challenges faced by TFL companies that result from the COVID-19 pandemic and the war in Ukraine and the directions of changes that result from them, both from the short-term and strategic perspectives. The relationships between the development of adaptability of supply chains and the increase in the competitiveness of entities enable us to verify the research hypothesis that, in the face of increasing disruptions and uncertainty in the business environment, strengthens the adaptability of supply chains producing a great potential in terms of maintaining the competitiveness of enterprises in the TFL industry. To gain and maintain a long-term competitive advantage, companies should strive to create a resilient supply chain that can withstand challenges and disruptions.
