This introduction frames the six original articles in this issue and the forum on "Corona A(e)ffects: Radical Affectivities of Dissent and Hope" around the concept of immaterial labor. Two full years into a pandemic that has uprooted place-based work for many, and forced even more indoors, away from public spaces, and onto screens, we reflect on the very material effects of present-day immaterial and emotional labor.
Years in Cultural Studies: 2013

n Eastern Europe, which is the focus of our study, different national scholarly traditions assigned their own place to the study of culture. Although the influence of the kulturologia (“culturology”) schools installed at Russian universities in the 1980s radiated out into Eastern European countries, local academic communities dictated the approach to the study of popular culture. While the Polish field of kulturoznawstwo was propelled by internal forces from the early 1970s onwards, in Czechoslovakia, kulturologie emerged as a new discipline around the fall of the Communist regime. Even so, it failed to take off and by 2012 had vanished completely from the Czech Republic. Central European countries were also affected by the German academic tradition of Kulturwissenschaften with its emphasis on philosophy and aesthetics. Our inquiry highlights the first international conference on cultural studies in the Czech Republic in 2013. It was during this event that a group of new postdocs from Charles University, including ourselves, raised the topic of changes in Eastern European popular culture due to the political transformation in 1989. This group had also arranged for Ann Gray, the final director of the UK Centre for Contemporary Cultural Studies (CCCS) to give a keynote address at the conference, a gesture that clearly linked the CCCS with the group’s own Centre for the Study of Popular Culture (CSPK) established three years earlier. From the outset, CSPK’s organizers aimed to promote the Anglo-American tradition of cultural studies both in the academy and among the general public. At the same time, they sought to retain their independence from academic structures and funding systems that might restrict their political activism.
First-Person Shooters, Tunnel Warfare, and the Racial Infrastructures of the US–Mexico Border
Authors: Llamas-Rodriguez Juan
Published: December 2021

Digital networked media actively participate in the nation-state’s and tech entrepreneurs’ efforts to imagine and manage the borderlands. These media facilitate virtual forms of thinking about the border both by offering popular reference points for the new technology being developed (e.g. Google Maps, Pokémon Go, Call of Duty) and by providing the actual tools through which these ideas can become actionable. This article analyzes one such reference point within the first-person shooter (FPS) console game Call of Juarez: The Cartel (Ubisoft, 2011). Like other border-themed video games, The Cartel borrows on colonial tropes and ideologies by creating playable narratives that invoke the untamable frontier and position racialized subjects as Other. Through its virtual modes of representation and interaction, the game encodes the racialization processes that continue to shape popular imaginings of the border. While its digital aesthetics animate a dynamic space of possibility, the logic of the first-person shooter reins in the expansiveness of animated space by restricting it to an interactive experience of tunnel warfare, an ideological orientation to the border underground that channels the players’ purposive motion into a space of direct confrontation and racial violence. Analyzing the narrative and procedural work of this ostensibly reactionary video game demonstrates how border infrastructures structure and shape specific forms of racial and colonial violence.
Back to Basics with Labor-Power
Authors: Cashbaugh Sean
Published: December 2021

Ted Striphas recently called for a return to the “problem of culture” within cultural studies. This is a political as much as a methodological provocation: “culture” became an object of analysis among mid-twentieth century scholars in dialogue with Marxist accounts of ongoing political crises. Taking a cue from this past, this essay rethinks culture in relation to the ongoing crisis in social reproduction via Social Reproduction Theory (SRT). Within some Marxist feminist currents, “social reproduction” refers to the reproduction of labor-power, Marx’s term for the capacity to work sold on the market in exchange for wages. Marxist feminists have theorized such matters at length via their analyses of the practices undergirding the reproduction of labor-power. SRT is not unfamiliar to cultural studies scholars, but those engaged with it tend to explore the representation of socially reproductive practices within culture rather than the ways culture itself contributes to labor-power’s reproduction. This is unsurprising. Historically, the field has discussed labor-power in terms of its circulation rather than its reproduction, detailing culture’s role in reproducing social systems. Drawing upon Michael Denning’s “labor theory of culture,” recent work in SRT, and Marx, I argue that culture functions in a socially reproductive capacity within the logic of capitalism. In doing so, it casts cultural struggle as a form of social reproduction struggle at the intersection of labor-power’s reproduction and that of the society that requires it. This essay constructs a systematic account of culture’s socially reproductive before using it to consider its historical expression in the current moment.

Published: December 2021

The results of the study of the influence of changes in the area of the flow section in the seat of selfacting valves with elastomeric elements on the characteristics of low-speed compressor stages are presented. A method of experimental research of low-speed compressor stages with the possibility of obtaining instantaneous parameters of the gas state in the working chamber of the stage and its integral characteristics and an experimental stand for its implementation have been developed. The results of comparative experimental studies have confirmed the effectiveness of the valve design with a variable cross-sectional area of the seat in comparison with known designs — an increase in the feed coefficient and isothermal indicator efficiency is at least 10...15%.

Authors:   Omsk State Technical University, Kalashnikov A. M. , Chernov G. I. ,   Omsk State Technical University, Yusha V. L. ,   Omsk State Technical University
Published: December 2021

In this scientific work, the process of expansion of wet steam with different values of the inlet degree of dryness in a screw expander is considered. The study is carried out on the basis of the developed mathematical model, which includes both the basic thermodynamic equations and the process of heat exchange of the working substance with the environment in the process of expansion. During the study of the expansion process in the area of wet steam in a screw expander, a mathematical model of this process is developed. The mathematical model is verified by comparing the results obtained on its basis with the results obtained by other researchers on an identical object. It can be seen from the results obtained that at values of the initial degree of dryness greater than 0,01, the distributions of pressures and temperatures practically do not depend on its value. When the initial dryness values are less than 0,01, it begins to have a significant effect on the distribution of pressure and temperature over the angle of rotation of the main rotor of the screw expander.

The Montreal Protocol and the Kigali Amendment have determined the need and deadlines of the replacement of hydro fluorinated refrigerants. Substances of natural origin with a low global warming potential are becoming an alternative to hydrofluorocarbons that are being withdrawn from circulation. Such an alternative corrects the vector of development of refrigeration equipment and entails the need to adapt or create new models of equipment taking into account the excellent properties of new refrigerants. However, the consumer’s choice is still based on the efficiency, cost and reliability of the equipment. Having studied the possibility of using new refrigerants, in the fields of using a scroll compressor, from the point of view of the operational properties of substances, we also noted some aspects of the influence of their thermodynamic and thermophysical properties on the working processes and design of compressor elements. Thus, we present a comparative analysis of the practical application and further prospects for the using of refrigerants in a scroll compressor, highlighting the current directions of studying this issue.
Análise termomecânica e probabilística de um pavimento de concreto em regime transiente modelado via método dos elementos finitos
Authors: Faria Albert Willian , Rocha Fábio Martin
Published: December 2021

O presente artigo apresenta um estudo estatístico e de sensibilidade de um pavimento de concreto submetido a um gradiente térmico em regime transiente. Dois modelos em 3D, um determinístico e outro probabilístico, são implementados no software ANSYS APDL, cuja base é o método dos elementos finitos, considerando-se a simetria geométrica e de carregamento termomecânico. O pavimento de concreto é composto por uma placa de concreto apoiada em uma base de concreto rolado e essa sob uma sub-base de poliuretano. Os elementos hexagonais Solid70 e Solid185 são utilizados na modelagem do pavimento, possuem respectivamente um grau de liberdade térmico e três graus de liberdade mecânicos por nó e um total de 8 nós. Incertezas na geometria e nas propriedades termomecânicas dos materiais constituintes do pavimento são inseridas nos modelos implementados utilizando a simulação de Monte Carlo, associada a amostragem por hipercubo latino. A análise de sensibilidade das variáveis de projeto também é realizada utilizando o coeficiente de correlação de Spearman. A distribuição das temperaturas sofridas pela placa de concreto utilizando o modelo determinístico foi comparada e validada de acordo com a literatura. O modelo probabilístico proposto permite demonstrar, de forma estatística, como as incertezas afetam as temperaturas e os valores máximos e mínimos para os deslocamentos verticais na placa de concreto. A análise de sensibilidade permitiu constatar a baixa significância da sub-base nas respostas mecânicas do pavimento. O modelo probabilístico também permite a obtenção das estatísticas e funções de distribuição acumulada de probabilidade das variáveis de saída da placa de concreto, que podem ser utilizadas no seu projeto.
LONGITUDINAL MULTIPLE RELATIONS OF PHYSICAL EDUCATION PARTICIPATION, SCHOOL GRADE, AGE, AND SEX WITH CARDIORESPIRATORY FITNESS CHANGES IN CHILDREN: A MEDIATOR ROLE OF CHANGES IN BODY COMPOSITION
Authors: Batista Lemes Vanilson , Baptista Moreira Rodrigo
Published: December 2021

To verify the multiple relations of physical education participation, school grade, age, and sex with longitudinal cardiorespiratory fitness changes in children and to identify if there is a mediator role of longitudinal body composition changes in these relations. Methodology: This is a longitudinal study, carried out from March to November of 2019, with children from 6 to 12 years old, 150 boys and 80 girls. Children were classified according to a cut point of 70% of participation in physical education classes (>70%= High PE x <70%=Low PE). Outcomes were Body Composition (BC): body mass index, skinfolds, waist to height ratio, and Cardiorespiratory fitness (CRF). Individual delta variation (D%), Cohens D, Bonferroni test, generalized estimative equations (GEE), and structural equations model (SEM) were estimated.  Results: The results show a general boy’s and girl’s increasing in BC variables and a decrease in CRF at follow-up which more strength in the Low PE group compared to the High PE group. The SEM model showed that Children in the High PE group have the most decrease in BC variables and it is a role to relations between the High PE group with increasing in CRF.  Conclusions: High PE group was associated with a D%CRF increase, it is an indirect association mediated by D% BC reduction. The SEM presents children that reduce BC also increasing CRF and vice-versa. The present study appoints that High PE participation is important to minimize the negative longitudinal effects of fatness on CRF.

Роль эллиптических интегралов в расчете гравитационного линзирования заряженной черной дыры Вейля, окруженной плазмой
Authors: Fathi M. , Villanueva J.R.
Published: December 2021

In this paper, we mainly aim at highlighting the importance of (hyper-)elliptic integrals in the study of gravitational effects caused by strongly gravitating systems. For this, we study the application of elliptic integrals in calculating the light deflection as it passes a plasmic medium, surrounding a charged Weyl black hole. To proceed with this, we consider two specific algebraic ansatzes for the plasmic refractive index, and we characterize the photon sphere for each of the cases. This will be used further to calculate the angular diameter of the corresponding black hole shadow. We show that the complexity of the refractive index expressions, can result in substantially different types of dependencies of the light behavior on the spacetime parameters.

В этой статье мы в основном стремимся подчеркнуть важность (гипер) эллиптических интегралов в изучении гравитационных эффектов, вызванных сильно гравитирующими системами. Для этого мы изучаем применение эллиптических интегралов при вычислении отклонения света при его прохождении через плазменную среду, окружающую заряженную черную дыру Вейля. Чтобы продолжить это, мы рассмотрим два конкретных алгебраических анзаца для показателя преломления плазмы и охарактеризуем фотонную сферу для каждого из случаев. Это будет использоваться в дальнейшем для вычисления углового диаметра соответствующей тени черной дыры. Мы показываем, что сложность выражений показателя преломления может привести к существенно разным типам зависимостей поведения света от пространственно-временных параметров.

Visualizing the three-step freezing process and three-phase reaction not predicted by the (NH4) 2SO4/H2O phase diagram
Authors: Bogdan Anatoli
Published: December 2021

According to the conventional phase diagrams, aqueous solutions freeze at the liquidus and are frozen/solid below the eutectic solidus. Herein, using differential scanning calorimetry (DSC) and optical cryo-microscopy (OC-M), we demonstrate that hy-poeutectic, eutectic 40 wt% (NH4)2SO4 and hypereutectic (NH4)2SO4/H2O remain liquid well below the eutectic solidus before freezing in three steps: fast-slow-fast. The first fast freezing produces a ramified ice microstructure (IM) and freeze-concentrated solution (FCS) containing up to ~70 wt% (NH4)2SO4. As temperature decreases further, the slow freezing of FCS precedes its fast freezing, which produces a striped IM and (NH4)2SO4 microcrystals. Videos recorded upon warming of frozen (NH4)2SO4/H2O reveal a new three-phase reaction, which is the recrystallization of ice and (NH4)2SO4 microcrystals into the lamellar eutectic ice-(NH4)2SO4 superlattice. This work demonstrates limitations of the (NH4)2SO4/H2O phase diagram and pro-poses an effective strategy for studying other deeply supercooled solutions whose behavior is not predicted by the phase dia-gram.
Asymmetric Synthesis of Propargylic alfa-Chiral Tertiary Amines by Reductive Alkynylation of Tertiary Amides Using Ir/Cu Tandem Catalysis
Authors: Agrawal Toolika , Perez-Morales Kimberly , Cort Jermaine , Sieber Joshua
Published: December 2021

The development of an asymmetric protocol for the reductive alkynylation of amides to access important alfa-chiral tertiary propargylic amines is reported using tandem Ir-catalyzed hydrosilylation/enantioselective Cu-catalyzed alkynylation. The reaction utilizes a Cu/PyBox catalyst system in the alkynylation step to achieve asymmetry and affords excellent yields with moderate to good levels of enantiocontrol while employing low Ir-catalyst loadings (0.5 mol %).
Conformational Sampling for Transition State Searches on a Computational Budget
Authors: Zhao Qiyuan , Hsu Hsuan-Hao , Savoie Brett
Published: December 2021

Transition state searches are the basis for characterizing reaction mechanisms and activation energies, and are thus central to myriad chemical applications. Nevertheless, common search algorithms are sensitive to molecular conformation and the conformational space of even medium-sized reacting systems are too complex to explore with brute force. Here we show that it is possible to train a classifier to learn the features of conformers that conduce successful transition state searches, such that optimal conformers can be down-selected before incurring the cost of a high-level transition state search. To this end, we have benchmarked the use of a modern conformational generation algorithm with our reaction prediction methodology, Yet Another Reaction Program (YARP), for reaction prediction tasks. We demonstrate that neglecting conformer contributions leads to qualitatively incorrect activation energy estimations for a broad range of reactions, whereas a simple random forest classifier can be used to reliably down-select low-barrier conformers. We also compare the relative advantage of performing conformational sampling on reactant, product, and putative transition state geometries. The robust performance of this relatively simple machine learning classifier mitigates cost as a factor when implementing conformational sampling into contemporary reaction prediction workflows.

Authors: Irfan Saira , Amin Rizwana , Khizar Umbreen , Saeed Wizra
Published: December 2021

Purpose: The purpose of this research was to determine which defense mechanisms can help to regulate the link between attitude toward change and organizational commitment. Psychological defenses are characterized as protective processes that help individuals maintain their integrity in the face of threat and danger. Previously, extant research has mainly emphasized organizational issues while individual psychological factors have remained largely ignored. Therefore, this paper seeks to investigate the moderating effects of psychological defense mechanisms on the relationship between employee attitude toward change and organizational commitment.
Design/Methodology/Approach: A total of 499 employees were chosen from the banks of the Southern Punjab, Pakistan, using a purposive sampling methodology. The information was gathered using validated questionnaires. The data was analyzed for descriptive statistics, correlation, and hierarchical multiple regression analysis.
Findings: The findings showed a positive correlation between employee positive attitude toward change and organizational commitment and a negative relationship between employee negative attitude toward change and organizational commitment. The results of the moderation analysis revealed that the association between employee attitude toward change and organizational commitment is negatively moderated by all three defense mechanisms.
Implications/Originality/Value: The findings highlight the significance of psychological factors during the organizational change process and suggests recruiting employees with positive attitudes.
Comparative estimation of a pain syndrome in patients after combined operations for coexistent pathology of anal channel and rectum with application of modern and standard surgical technologies
Authors: Balytskyy V. V.
Published: December 2021

Objective. Comparative estimation of the pain syndrome in patients with concomitant pathology of anal channel and rectum after performance of combined operations, using modern high-frequency electro-surgical and radio-surgical apparatuses, as well as conventional scalpel.
Materials and methods. The results of surgical treatment of 689 patients with concomitant pathology of anal channel and rectum, using apparatuses of a high-frequency electro-surgery and radio-wave surgery, were analyzed, using the pain syndrome estimation on 1-7th postoperative day. The patients were distributed into 4 investigation groups and a control group, consisting of 112 patients, operated on using metallic conventional surgical scalpel.
Results. The pain syndrome on the first postoperative day was mostly expressed in patients of control group, for anesthesia they needed (4 ± 1) ml of 2% solution of promedol, while the patients of the first, third and fourth groups investigated, in which, accordingly, apparatus of radio-wave surgery «Surgitron» and high-frequency electro-surgical apparatuses «EFA» and «KLS Martin» were used, needed for anesthesia (2 ± 1) ml of 2% solution of promedol. While application of the electro-surgical high-frequency apparatus «ERBE ICC 200» the necessity for the 2% solution of promedol for anesthesia have constituted (3 ± 1) ml.
Conclusion. Combined operations, using modern apparatuses of high-frequency electro-surgery and radio-wave surgery give significantly better results, than application of conventional surgical metallic scalpel, because it produces significantly reduced pain syndrome due to thin layer of coagulation necrosis, promoting formation of delicate elastic cicatrix and preventing development of cicatricial strictures of anal channel in postoperative period.

Cyanoboletus macroporus belonging to C. pulverulentus species complex is designated as a new species from the moist temperate and sub-alpine oak forests of Pakistan after in depth macroscopic, microscopic and phylogenetic analyses using the ITS region of nrDNA as well as comparison with allied taxa. This species belonging to Boletoid group is morphologically distinguished from allied taxa (Cyanoboletus flavosanguineus, C. hymenoglutinosus, C. pulverulentus, C. rainisii, and C. sinopulverulentus) by wider openings of pores. C. macroporus is also phylogenetically distinct from C. sinopulverulentus and C. pulverulentus, the most closely related species. Phylogenetic analysis outlined the existence of previously unknown species of this genus. Field photographs of fresh basidocarps and line drawings of micro-characters are provided along with a phylogenetic tree as well as a comparison table and a key of distinctive features of all the species in this genus. This is the first authentic species belonging to Cyanoboletus from Pakistan. Previously, only C. pulverulentus has been mentioned in literature, but no morphological data is available regarding this report. With the addition of this taxon, species number of Cyanoboletus will increase to eight. From Pakistan, despite of the fact that there is great diversity of mushrooms in moist temperate areas (Yousaf et al. 2012), this is the first study that describes a species belonging to Cyanoboletus genus. Previously only one ambiguous species, Cyanoboletus pulverulentus, has been mentioned in literature (Iqbal & Khalid 1996), but with no available materials that could confirm this finding. In this study, Cyanoboletus macroporus is described as a new to science and increase the current species number of Cyanoboletus to eight.

Introduction: Some studies indicated that antlions (Myrmeleon sp.) is traditionally used by many people in Indonesia as a diabetes treatmenter. However. reseach has not been done to find the effect of antlion extract in pancreas, an important organ in diabetes mellitus pathophysiology. Objective: To prove the effect of antlion extract towards histopathological feature of pancreas in diabetic mice.Methods: In the post test only control group design, 25 Swiss mice were divided into five groups. Normal group (Nor-G), Negative control group (Neg-G), and the other 3 groups were intraperitoneally injected with Streptozotocine 200 mg/kg to induce diabetic state. In Neg-G had no antlion treatment, whereas in At-14, At-28, and At-56 were treated with antlion extract at the dose of 14, 28, and 56 mg/kg BW respectively for 24 days. Pancreas then collected and prepared to be examined under microscope with 400x magnification. The score of pancreatic islet injury was determined by assessing structural damage and inflammatory cells infiltration. Kruskal-Wallis and Mann-Whitney were adopted as statistical analysis.Results: Mann-Whitney analysis indicated that the score of pancreatic islets injury in At-56 was significant lower compared to that of Neg-G, p<0.05. The score of pancreatic islets injury in At-56 also significant lower compared to that of At-14 and At-28, p<0.05. In contrary, when compared to that of Nor-G, the pancreatic islets injury in At-56 was not signicantly lower, p>0.05.Conclusion: Antlion extract treatment at the dose of 56 mg/kg BW was capable of reducing pancreatic islet injury in diabetic mice induced by streptozotocine.

Published: December 2021

The paper gives a review of the studies concerned with operation of vessels in brash ice. Recently, the ice conditions have received an ever increasing attention of the researchers related to the fact that shipping in the Arctic regions and freezing seas, as well as in inland waterways has been scaled up. One of the important fields of brash ice studies is specifics of sailing under these conditions and primarily determination of the ship ice resistance. The paper shows that theoretical methods combined with physical modeling in ice basins are used for determination of the ship ice resistance under brash ice conditions. The paper traces the evolution of theoretical models utilized for calculations. It is mentioned that the models are mainly based on loose material mechanics. A rapidly developing computer modeling of ship motion in brash ice based on discrete element method is considered. Physical modeling techniques used for modeling brash ice in ice basin are described, and challenges of experimental investigations are discussed. It is pointed out that experimental studies in ice basin can provide valuable data not only about ship ice resistance but also about the mechanisms giving rise to ice channels filled with brash ice. The paper describes the methods for studying operation of ship propellers in brash ice conditions. It is concluded that further research into brash ice is needed.
