Authors:   National Aviation University, Ukraine, V Sineglazov , I Boryndo ,   National Aviation University, Ukraine
Published: April 2023

In this paper analysis of modern augmented reality algorithms based on mobile devices was done. As a result, algorithmic shortcomings were identified and the usage of convolutional neural networks was proposed. Within the research the qualitative analysis of modern architectures of convolutional neural networks was carried out and their separate shortcomings at use in systems on the basis of processor architecture ARM was shown. As a result of this research it was found that to achieve the target accuracy and speed of the system it is important to use a hybrid convolutional neural network, which significantly improves the quality criteria of the system. The optimal structure and parameters for initialization and training of a hybrid convolutional neural network system used for augmented reality are obtained. The optimal training sample was formed and the use of pre-trained HCNN on another device of ARM architecture was described.
Formation of wireless sensor network protection system parameters for intrusion detection in the form of false event flows
Authors:   Lviv Polytechnic National University, Ukraine, O Belej
Published: April 2023

Wireless sensor networks with stationary and mobile sensor nodes are studied. For mobile nodes, in addition to sensor nodes, the influence of node movement speed on the duration of the network life cycle for mobile AdHoc networks was also studied. When studying the impact of erroneous events on the sensor field, it was established that providing sensor nodes with mobility allows increasing the life cycle of the network. A model of intrusion into a wireless sensor network with the aim of shortening its life cycle has been developed, which differs from known models in that false event streams are used to achieve this goal. The model is developed based on typical geometric, quantitative and energy parameters of wireless sensor networks using a basic clustering algorithm for a homogeneous mobile sensor network under conditions of Poisson network intrusion and deterministic error event flows. It is established that the duration of the life cycle of a wireless sensor network can significantly depend on the type of the flow of erroneous events and, other things being equal, under the influence of a deterministic flow can be almost half as long as under the influence of a flow of erroneous events. the impact of the flow of false events. the Poisson flow effect. Detection of false events in a wireless sensor network can be considered as a target tracking task, and to detect false events with a given probability, taking into account the limited capabilities of sensor nodes, it is advisable to use the architectural characteristics of the network, the distribution of the density of nodes on the sensor field.

New experimental data of angular distribution cross-sections for the 10В(15N,14С)11С reaction at the energy Еlab(15N) = 81 MeV were obtained for the ground states of 14С, 11С nuclei and 2.00 MeV (1/2-), 4.31 MeV (5/2-), 4.31 MeV (3/2-) excited states of 11С nucleus. The experimental data were analyzed within the coupled-reaction-channels (CRC) method. In the CRC calculations, the 15N + 10В Woods - Saxon (WS) optical potential obtained from the CRC analysis of the experimental elastic and inelastic data of these nuclei was used and parameters of the 14С + 11С WS optical potential were deduced from the analysis of the 10В(15N,14С)11С reaction experimental data. Spectroscopic amplitudes of nucleons and cluster transfers were calculated within the translation-invariant shell model.

Proton beam writing is a promising lithography method that is being developed in many countries. This method has significant advantages over other lithography methods, amongst all, there is the absence of the need for prefabricated pattern masks and a high aspect ratio of fabricated structures. Numerous publications demonstrate prospective applications of proton beam writing in different fields related to micro- and nanostructures fabrication. Proton beam writing may be used both for nanoelectronics and three-dimensional microstructures with a high aspect ratio. Work on proton beam writing technology is being conducted at the Institute of Applied Physics of the National Academy of Sciences of Ukraine. Last years there were introduced vector proton beam writing method, an electrostatic blanker system for proton beam distortion, and experiments on proton beam writing on chitosan films were conducted, including the films covered with thin films of metals and metal compounds.

The aim of the paper is to supply updated air convective coefficients by means of three empirical correlations set forth by Zukauskas, Churchill and Hilpert for cylindrical bodies in cross-flow. In this study, low Reynolds numbers and air velocities within the range of were considered, hence, sundry values of convective coefficients were obtained and applied in a lumped heat capacity model. Finite element analysis simulations were implemented, exhibiting good conformity based on these correlations. The findings show that among the three methodologies, Zukauskas's correlation presents minimum standard deviation and the maximum standard deviation is presented by Hilpert's correlation , Churchill correlation presents a standard deviation of . The results are reliable and can therefore be used for analyzing heat convection.

Published: April 2023

It is an important research area to define the bioactivities of plant fractions and to create appropriate utilization areas for them. Although Cotinus coggygria, which is widely used in folk medicine, which grows from Europe to the center of China, has a wide variety of bioactivities, there is limited information about its influence on the immune system.The anti-proliferative effects of Cotinus coggygria extract on stimulated peripheral blood mononuclear cells (PBMC) were determined by CFSE dilution method. The effects of the extract on peripheral blood T and natural killer (NK) cells were followed by their proliferative responses. Annexin V / PI staining method was used to evaluate the apoptotic effects of the extract on PBMCs. The effects of the extracts on expression levels of IL-1?, IL-2, IL-4 and IL-10 genes were investigated.Effect of Cotinus coggygria on the proliferation of T cells and NK cell subsets were decreased in a dose dependent manner. Anti-proliferative effect of Cotinus coggygria extract on stimulated PBMCs was not directly related to its apoptotic properties, it also changes the cytokine genes expression on PBMCs. Our study suggests that Cotinus coggygria methanol extract, whose anti-inflammatory effects have not been investigated yet, may be a pioneer in the identification of new molecules with anti-inflammatory properties and the development of related therapies.
"Vi som bor här - vi vet!": En platssociologisk studie om ungas sociala organisering, identiteter och tillhörigheter i ett miljonprogramsområde
Authors:   ,   Linnaeus University, Faculty of Social Sciences, Department of Social Studies, Valizadeh Carolin
Published: April 2023

The aim of the thesis is to examine how young people construct – i.e., make meaning about and socially organize – two adjacent residential areas in Malmö. Central to this is understanding how young people organize the public spaces, as well as construct social identities and a sense of belonging in relation to these places. Concepts such as social identities, group identities, local communities and idiocultures are used to understand young people’s relations with the areas, and with other young people residing there. To understand the complexity of place, I develop a multidimensional concept that takes into account five dimensions: localization; events and activities; populations and social relations; physical environment;values and qualities. My research design employed a combination of methods, drawing primarily on an ethnographic approach. I utilized three different data collection techniques: field observations, focus group interviews,and “go-alongs”. A total of 40 young people, ranging in age from 15 to 25 years, participated in my study. My empirical findings highlight how the values and qualities attributed to the areas by the young people could be said to constitute two distinct discourses: one describes the areas with an emphasis on safety,belonging, and community, while the other emphasizes fear, distance, and isolation. Both discourses were conveyed by heterogeneous groups in terms of class background, ethnicity, age, and gender. What distinguished the young people expressing safety and belonging from those describing fear and distance was primarily the extent of their local networks and experiences of “hanging out” in the areas. Young people spending a lot of time in the areas imagined themselves belonging to a local community based on place, class, ethnicity, and gender identities, making it difficult to belong for those who did not enact these identities according to local norms. Young people who frequently hung out in the areas, claiming different places and controlling access through language, behaviour, and subtle rules was further complicating placetaking for other groups of young people.
Direction of trade of Indian arabica coffee
Authors: Kumar P. Sai , Kishore N.T. Krishna
Published: April 2023

Coffee (Coffea) is one of the most valuable commercial crops and the second most traded agricultural commodity on a global scale. Around 100.55 lakh MT of coffee will be consumed worldwide in 2019–20. South America, Asia, Africa, and Central America were identified as major coffee-growing regions, comprising of countries Brazil, Vietnam, Colombia, Indonesia, Honduras, Ethiopia, India, Uganda, Peru, and Mexico. While Brazil and Vietnam contribute 50 per cent of the world’s coffee, India stands at 7th position in terms of production and exporting 2,61,374 GBE (Green Bean Equivalent - Quantity In MT) of coffee to the world, worth of Rs. 4131.82 crores during 2019-20 and contributes 2.5 per cent to the nation’s primary sector export earnings. Markov Chain analysis helps to understand the export pattern of Indian arabica coffee. Italy, Belgium, Germany, U.S.A, Switzerland, United Kingdom, France, Australia, Russian Federation and some other countries are the major importers of Indian arabica coffee. The only consistent importer of Indian arabica coffee was Italy. Despite having many major importers, India was unable to maintain a consistent share of the global market. Because of increased competition, arabica coffee’s export share has been declining. One of the major reasons for this decline was tough competition from Brazil, Vietnam, Colombia, Indonesia, Honduras, and Ethiopia. This shows that there is a need to frame policies in favor of increased coffee marketing to gain the competitive advantage in the global coffee market.
A Study of the Network Effect on Exports in the Defense Industry
Authors:   Korea Association for International Commerce and Information, Jeong Ho-Taek , Lee Jae-Hwa
Published: April 2023

The main purpose of this study is to contribute to the investigation of explanatory variables and networks effect on exports in the defense industry. In particular, it attempts to examine the role of two channels of economic and non-economic networks in the gravity equation of exports; economic networks are trade, FDI and FTA, non-economic networks are military expenditure and military alliance. The basic and the augmented gravity models are estimated with an annual cross-section data set of year 2020 for 44 countries.
The estimation results demonstrate that military expenditures explain the bilateral export in the defense industry better than GDP does as an economic scale variable in the equation. Also the evidence of the effect of FDI is statistically significant in the estimation, whereas no evidence for effects of trade and FTA have been found. In addition, there is no further evidence for the role of military alliance between trade partners for exports in defense industry.
The results imply that military expenditure of import country and FDI relation has a strong relationship with export in the defense industry. Thus, it also emphasizes the policy implication for taking into account of the linkage between export and FDI activity in promoting export of defense industry.

Authors:   Korea Association for International Commerce and Information, Kim Boo-Gon , Kwon Hye-Mi , Park Tae-Hwa
Published: April 2023

The role of social enterprises can be cited as an alternative to solving the difficulties of small business owners caused by COVID-19. The results were derived by empirically analyzing the impact of new product development capabilities, product quality levels, price competitiveness, customer retention capabilities, purchase intentions, the number of employees and the number of vulnerable employees on financial performance.
This study shows that financial performance can be improved when the corporate capabilities of social enterprises are mutually harmonized. Since the Social Enterprise Promotion Act was enacted in 2007, it is significant that it will contribute to enhancing the sustainability of social enterprises and establishing the original identity of social enterprises by analyzing and presenting factors that affect financial performance.
As an implication, if research related to the performance of social enterprises develops social enterprises and creates a market that realizes the friendly image and social values of social enterprises themselves, social enterprises will become a subject in Korean corporate society.

ABSTRACT: This study assessed the nitrogen nutrition index, morphogenic characteristics and tiller structure of Alexandergrass (Urochloaplantaginea (LINK) Hitch) pasture submitted to different nitrogen (N) levels (zero, 150 or 300 kg ha-1 of N). The experimental design was entirely randomized with repeated measures arrangement. The experimental animals were Angus heifers under rotational stocking grazing method. The number of animals was variable to keep 30±5 cm post-grazing sward height. Nitrogen nutrition index increased linearly according N levels (Ŷ = 59.8 + 0.1216N; P < 0.0001; r²=0.53). The leaf appearance rate adjusted to a positive linear regression model according the thermal sum (TS) with zero of N (Ŷ0N = 0.0077 + 0.0000087TS; P = 0.0308; r² = 0.72) and 150 kg ha-1 of N (Ŷ150N = 0.0020 + 0.000021 TS; P = 0.0022; r² = 0.92). The use of 300 kg ha-1 of N did not alter the leaf appearance rate (0.0124 leaf degree-days-1). The use of up to 300 kg ha-1 of N increases the Alexandergrass nitrogen content. The leaf appearance rate in Alexandergrass is modified using N while the morphogenic characteristics leaf expansion, stem expansion, phyllochron, leaf lifespan, leaf elongation duration and tiller structure are not altered by N utilization.

Published: April 2023

RESUMO Diversos pesquisadores têm buscado compreender o que leva os indivíduos a cumprir as Políticas de Segurança da Informação - PSIs instituídas pelas organizações. Uma dessas correntes defende que a cultura representa um importante fator, destacando-se a presença de estudos envolvendo cultura organizacional em detrimento da cultura nacional. Dadas as especificidades culturais do país, estudar a relação entre seus aspectos culturais e o cumprimento das PSIs pode trazer insights sobre a gestão da segurança da informação nas organizações brasileiras. Assim, objetivou-se neste estudo analisar como a cultura de segurança da informação influencia os indivíduos no cumprimento das políticas de segurança da informação e na diminuição da ocorrência de falhas de segurança associadas ao “jeitinho brasileiro”. O estudo caracteriza-se como uma pesquisa survey aplicada a 196 funcionários de diferentes organizações brasileiras. Os resultados indicaram que a consciência de segurança da informação influencia positivamente o comportamento planejado dos indivíduos e negativamente o “jeitinho”, sendo que ambos influenciam o cumprimento das normas de segurança da informação estabelecidas pela organização. Identificou-se, ainda, uma forte relação entre o cumprimento das normas e a diminuição de falhas de segurança associadas ao “jeitinho brasileiro”.

Published: April 2023

ABSTRACT: Intracranial tumors occurring in specific brain regions, such as the cerebellopontine angle, may be associated with cranial nerve dysfunction and dysphagia in humans and animals. Although dysphagia is a known risk factor for pneumonia, only postoperative pneumonia has been investigated in veterinary medicine. This study aimed to describe the clinical and pathological features of dogs with untreated intracranial meningiomas and concomitant pneumonia. Data from post-mortem examination registries from 2011 to 2021 were used (n=23). The frequency of pneumonia and other characteristics were compared between dogs with meningiomas in the ventral rhombencephalon region (VR group; n=13) and those with meningiomas in other intracranial sites (OIS group; n=10). The frequency of pneumonia was higher in the VR group than in the OIS group (n=5 vs. n=0; P=0.039). Plaque-like lesions were also more common in the VR group than in the OIS group (P=0.012). Dogs with concomitant pneumonia had cerebellopontine angle (n=3) and basilar meningiomas (n=2), mainly plaque-like lesions extending to or from other brain areas. In dogs with concomitant pneumonia, meningiomas had invasive (n=5) and compressive (n=3) growth behaviors and nerve roots involved in the swallowing process were frequently affected. Microscopically, these meningiomas were classified as atypical (n=4) and meningiomas (n=1). The reported clinical signs included anorexia (n=3), adipsia (n=1), and dysphagia (n=1). Our findings suggest untreated dogs with ventral rhombencephalon meningiomas may develop cranial nerve damage and aspiration pneumonia.

Authors: Rodrigues Luciana Miranda , Machado Cristiane Gouvêa , Maksud Ivia
Published: April 2023

ABSTRACT Objective: to discuss the process of allowing blood donation by the LGBTQIAP+ community by the Federal Supreme Court in contrast to the Legislation of the Regulatory Agency for Blood and Blood Components. Method: this is a reflective study, considering the principles and concepts of Pierre Bourdieu’s symbolic capital as a theoretical-methodological framework. Analysis was carried out in documents that dealt with the permission of blood donation by gay and bisexual men, such as bills, FSC decisions and media materials relevant to the proposed theme. Results: we argue that two historical events were decisive for the vote on the act of unconstitutionality by the Federal Supreme Court: the mobilization of lesbian, gay, bisexual and transgender social movements and the coronavirus pandemic. Conclusion: validation of the right to blood donation contributes to the exercise of citizenship of lesbian, gay, bisexual and transgender people.

ABSTRACT Objective: To describe the patterns of overall mortality and mortality from external causes and the temporal evolution in the municipalities of the Paraopeba River Basin, before the socio-environmental disaster of the Brumadinho dam and, additionally, to investigate the correlation between mortality and socioeconomic deprivation in these municipalities. Methods: Global Burden of Disease Study mortality estimates for 26 municipalities in the state of Minas Gerais, Brazil, were analyzed. Rates of overall mortality and mortality from external causes were estimated in the triennia (T) T1 (2000 to 2002), T2 (2009 to 2011), and T3 (2016 to 2018). Pearson’s correlation coefficient measured the association between mortality rates and socioeconomic deprivation, according to the Brazilian Deprivation Index (IBP). Results: There was a decrease in overall mortality in the Paraopeba River Basin from 717.7/100 thousand to 572.6/100 thousand inhabitants, and in most municipalities between T1-T3. Mortality from external causes increased from 73.3/100 thousand to 82.1/100 thousand, and it was higher in these municipalities compared with the mean for Brazil and Minas Gerais. Deaths from suicide and interpersonal violence increased from 29.6/100 thousand to 43.2/100 thousand in most of the 26 municipalities. Death rates due to unintentional injuries decreased during the period, and those due to transport injuries, increased. There was a positive correlation between socioeconomic deprivation and the percent change in mortality rates. Conclusion: Despite the strong presence of mining activity in the region, such did not reflect in the improvement of the sanitary situation. Death rates due to external causes increased in the period, associated with inequalities, which must be considered in the planning for the recovery of the disaster areas.
Pandemia do coronavírus e a retomada das políticas monetárias não convencionais nos EUA: algumas considerações à luz da crise financeira de 2007/08
Authors: Paula Luiz Fernando de , Saraiva Paulo
Published: April 2023

Resumo O presente artigo analisa, preliminarmente, as políticas monetárias não convencionais adotadas pelo Federal Reserve, no período de 2020 até março de 2021, para conter os efeitos recessivos da crise de saúde pública mundial causada pela pandemia do coronavírus. Para tanto, como grande parte das medidas monetárias atuais foram adotadas durante a crise financeira de 2007/08, buscou-se fazer um comparativo, bem como um contraponto, em virtude de a origem das duas crises serem diferentes. Na crise do subprime ocorreu um contágio do setor financeiro para a economia real, ao passo que na crise atual observa-se o inverso, ou seja, uma queda brusca da demanda e oferta que se propaga para o sistema financeiro. Sustenta-se que o Fed se beneficiou da experiência de políticas monetárias não convencionais implementadas a partir de 2008, com a diferença de que, enquanto tais políticas foram adotadas gradualmente após a crise financeira de 2008, no caso da crise do “coronavírus”, elas foram implantadas imediatamente de modo a se antecipar dos efeitos da crise no setor bancário e no lado real da economia.

PRAGMÁTICA COMO CIÊNCIA SOCIAL
Authors: Silva Daniel do Nascimento e
Published: April 2023

Resumo A partir de pesquisas de orientação etnográfica, como as de Stephen Levinson e Elinor Ochs, e social, como as de Jacob Mey e Joana Plaza Pinto, o artigo assume uma postura particular sobre a pragmática linguística. Nomeada originalmente por Peirce e firmada como perspectiva - em vez de disciplina -, a pragmática abriga pesquisadores/as de diversas tradições. Pessoas com trabalho pragmaticamente orientado ao estudo linguístico podem estar filiadas a áreas como a sociolinguística, a antropologia linguística, a linguística aplicada, a etnometodologia etc., mas sugiro uma semelhança de família: a pragmática vista como ciência social - i.e., tanto área etnograficamente orientada ao papel, às ideologias e à agência dos usuários da linguagem, quanto ciência “na sociedade”, engajada. O artigo revisita etnografias linguísticas na Oceania e África, bem como trabalhos de orientação semântica. Conclui-se, com Rajagopalan, que uma diversidade de problemas de pesquisa dessa perspectiva são refinamentos da ação situada dos sujeitos.
PROSODY, RELEVANCE AND MANIPULATION IN POLITICAL DISCOURSE
Authors: Labastía Leopoldo Omar
Published: April 2023

Abstract The aim of this paper is to examine the role of intonation in political discourse in River Plate Spanish as a means to manipulate audiences into accepting questionable assumptions. The analysis of intonation is carried out in the Autosegmental-Metrical model applied to Argentinian Spanish and its interpretation is made in the framework of Relevance Theory. Some extracts from three interviews of two politicians and a presidential address are analysed, using PRAAT (BOERSMA; WEENINCK, 2020), a software for speech analysis, and interpreted using the Sp_ToBI transcription system. The analysis shows that level and rising intonation, often associated with background information, can be used to indicate, together with other linguistic devices, that information is to be processed as forming part of the common ground shared with the audience, and thus beyond questioning. In this way, information favourable to the speaker is made more accessible and attention is diverted from critical information.

Abstract Based on Rauen’s goal-conciliation theory, Sperber and Wilson’s relevance theory, and Brown and Levinson’s politeness theory, we model in this essay the utterance “Can you pass the salt?”-taken as a classic example of a polite request between politeness theorists-assuming the mobilization of a polite or attenuated speech act contributes to the accomplishment of practical goals. Next, we discuss the modeling considering some criticisms produced by second-wave politeness studies and politeness relevance-theoretic studies. We conclude that politeness aspects are part of intentional action plans, affecting the design of the lowest level practical goal superordinating the respective informative and communicative subgoals. We claim the speaker defines-in the scope of that lower-level practical goal-the speech-act, the politeness super-strategy, and the formulation of the polite utterance considering a palette of linguistic possibilities.

Abstract Introduction Women who have engaged in sex work have been a stigmatized, marginalized, and socially alienated community. Particularly, in the case of trans women, there is a bigger percentage of violence. Objective To analyze the life story of a trans woman who works in sex work, based on an intersectional and occupational analysis. Method We used a qualitative study based on the Life History research technique, considering elements of the occupational narrative interview. Results From her history, we can see that there are elements that have intersected throughout her life, such as the domains: structural, disciplinary, hegemonic, and interpersonal. And that her occupational choices have been strongly influenced by her context within occupational apartheid, seeking to generate spaces of resistance and agency in the face of different adversities. Conclusions These situations make her living conditions precarious and alert the influences of economic, political, and heteronormative systems, among others, in determining people's lives.
Coopetition Against an Amazon

Published: April 2023

This paper analyzes cooperative data-sharing between competitors vying to predict a consumer's tastes. We design optimal data-sharing schemes both for when they compete only with each other, and for when they additionally compete with an Amazon – a company with more, better data. We show that simple schemes – threshold rules that probabilistically induce either full data-sharing between competitors, or the full transfer of data from one competitor to another – are either optimal or approximately optimal, depending on properties of the information structure. We also provide conditions under which firms share more data when they face stronger outside competition, and describe situations in which this conclusion is reversed.
Impact of Nanotechnology on Differentiation and Augmentation of Stem Cells for Liver Therapy
Authors: Anwar Ifrah , Ashfaq Usman Ali
Published: April 2023

The liver is one of the crucial organs of the body that performs hundreds of chemical reactions needed by the body to survive. It is also the largest gland of the body. The liver has multiple functions, including the synthesis of chemicals, metabolism of nutrients, and removal of toxins. It also acts as a storage unit. The liver has a unique ability to regenerate itself, but it can lead to permanent damage if the injury is beyond recovery. The only possible treatment of severe liver damage is liver transplant which is a costly procedure and has several other drawbacks. Therefore, attention has been shifted towards the use of stem cells that have shown the ability to differentiate into hepatocytes. Among the numerous kinds of stem cells (SCs), the mesenchymal stem cells (MSCs) are the most famous. Various studies suggest that an MSC transplant can repair liver function, improve the signs and symptoms, and increase the chances of survival. This review discusses the impact of combining stem cell therapy with nanotechnology. By integrating stem cell science and nanotechnology, the information about stem cell differentiation and regulation will increase, resulting in a better comprehension of stem cell-based treatment strategies. The augmentation of SCs with nanoparticles has been shown to boost the effect of stem cell-based therapy. Also, the function of green nanoparticles in liver therapies is discussed.

La afasia es un problema médico causado por un daño en las partes del cerebro responsables del lenguaje. Para la mayoría de las personas, estas áreas están del lado izquierdo del cerebro. Usualmente, la afasia ocurre de repente; a menudo es resultado de una lesión en la cabeza, un ataque al cerebro, o puede desarrollarse lentamente a partir de un tumor cerebral en crecimiento o de alguna enfermedad localizada en este importante órgano. La afasia afecta la capacidad de las personas de expresarse y comprender el lenguaje oral y escrito, el tratamiento principal de la afasia es la terapia del lenguaje, luego que se haya tratado la causa subyacente. Todo esto buscamos presentarlo al público de una forma sencilla manteniendo el balance entre ciencia y saberes prácticos que necesita dominar un profesional en salud.
Migration and the Dystopian Imagination of European Border Regimes
Authors: Stock Adam
Published: April 2023

Inward migration has long troubled the European political imagination. For example, an emphasis on fortification and low immigration was key to the civilisational fantasy of many early modern European literary Utopias. The dominant contemporary political framing of irregularised migration as a European problem thus leans on an imagined transnational ‘European civilisation’, concretised in the contemporary EU but with roots stretching back centuries. This article examines critical cultural treatments of legal and policy frameworks, grounded in a (supra-)nationalist civilisational myth, which now determine the treatment of irregularised migrants. Specifically, I examine three cultural texts (a novel, a film, and documentary artwork) produced in the years immediately preceding the development of the current Dublin III Regulation, which determines how and where asylum claims are processed in the EU. These three realist primary texts counter the official techno-scientific discourse of territorial integrity using science fictional narrative strategies, generic conventions, and tropes: the 2012 documentary artwork Liquid Traces: The Left to Die Boat Case by Forensic Architecture uses science fictional visualisations to directly confront the deadly effects of European bordering in the Mediterranean. Aki Kaurismäki’s film Le Havre (2011), shows how twentieth-century history haunts contemporary migration fears by spatialising multiple temporalities in the titular city. Finally, Chika Unigwe’s novel On Black Sisters’ Street (2009), explores the colonial dynamics of irregularised migration and the complexities of individual agency, producing a form of critical dystopian engagement with the social and political conditions of the present without being a generic dystopia. These three texts expose the dangers and violence of European bordering, and counter the science fictional civilisational fantasies of its policies. They share an emphasis on the need for solidarity, resistance, and, via encounters with the spectral presences of Europe’s past, they demand forms of historical justice which will break with contemporary dystopian conditions and the hard borders of the present.
Effect of operating conditions of mine monorail locomotives on the durability of drive wheel polymeric rims

Published: April 2023

An increase in the rate of coal mining and a reduction of its prime cost can be ensured by comprehensive mechanization and automation of the system of mine auxiliary transport through the widespread introduction of overhead monorail tracks. The potential use of mine monorail tracks are conditioned by the following factors: low payload ratio of the train; reduction of the mine workings cross-section area due to transfer of auxiliary transport to the upper part of the workings; high operational safety; as well as the possibility of dismantling the track in the unused sections and subsequently installing it in new mine workings. The use  of rubberized rollers in the drives of mine monorail locomotives enables the coefficient of adhesion of the wheel with the monorail to be increased. It also reduces dynamic loads and the noise level during operation. The purpose of this research is to assess the durability of polymeric rims of drive wheels for mine monorail locomotives, taking into account their operating conditions. Stress distribution over the contact area of the wheel rim with the monorail was determined, enabling the development of measures to increase the service life of drive wheels of mine monorail locomotives to be developed. It was established that the effect of the monorail track deformation has no significant impact on the durability of drive wheel rims of mine monorail locomotives. A mathematical model was obtained to determine the durability of drive wheel polymeric rims, taking into account the maximum dynamic forces arising during the contact of drive wheels with the monorail. The durability of wheel polymeric rims of mine monorail locomotives was assessed in accordance with the Bailey criterion with regard to the maximum values of dynamic contact loads arising during the monorail train movement. It was also established that an increase in the carriage mass from 20 to 47 kN leads to 32 % less durability of a monorail locomotive drive wheel rim (from 8700 to 5900 hours).

Auch Kalter Krieg in Arkadien
Authors: Bösch Frank
Published: April 2023

Die Havellandschaften zwischen Wannsee und Potsdam gelten bis heute als Herzstück des «preußischen Arkadiens». Schlösser, Parks und Villen säumen die Ufer und eröffnen malerische Blicke auf verschlungene Seen und Ufer. Kaum etwas zeugt noch davon, dass hier bis 1989 eine kaum überwindbare Grenze Deutschland teilte. Die Glienicker Brücke, die den Ortsteil Wannsee und Potsdam seit dem 17.Jahrhundert verbindet, nannte die SED zwar «Brücke der Einheit», aber tatsächlich wurde ihre Sperrung zu einem Symbol der deutschen Teilung. Die innerdeutsche Grenze verwandelte damit eine Kulturlandschaft, die über Jahrhunderte zum ästhetischen Wohlgefallen und zur Zerstreuung entstanden war, in eine politische Sperrzone des Kalten Kriegs. Biergärten am Wasser, romantische Spazierwege und verwunschene Badestellen verkehrten sich in auch nachts grell erleuchtete Grenzanlagen mit ausgehungerten Schäferhunden und Soldaten mit Schießbefehl.
Das Strandbad

Mein Vater war ein enthusiastischer Sportler, der noch im Alter jedes Jahr das goldene Sportabzeichen wiederholte und jedes Mal, wenn er mit der Urkunde nach Hause kam, erleichtert den Satz sagte: «Es ging noch ganz einfach.» Warum er sich der Tortur unterzog, war nicht herauszufinden. Außerdem war er ein mit buchstäblich allen Wassern gewaschener Paddler, der alle großen Flüsse Deutschlands, wenn nicht Europas, gepaddelt hatte und nun am Sonntag die sportlich nicht gerade herausfordernden Gewässer rund um Berlin durchpflügen musste. Seine Boote – Klepper, auf diese Marke ließ er nichts kommen – lagen in einem der Post gehörenden Bootshaus in bester Lage am Kleinen Wannsee, zwei Sprünge über Land vom Kleist-Grab entfernt. Wenn wir ihm nicht entwischen konnten, musste eines der vier Kinder mit ihm am Sonntag aufs Wasser gehen, was keiner von uns als besondere Auszeichnung empfand.
