Shallow-water Sponges from a High-sedimentation Estuarine Bay (Brunei, Northwest Borneo, Southeast Asia)
Authors: Setiawan Edwin , Relex David , Marshall David J.
Published: October 2021

Tropical estuaries are important habitats for invertebrates including sponges, a group of marine organisms that fulfill significant ecological roles and provide ecosystem services. Here, we describe the sponge fauna from Pulau Bedukang, a small island in a turbid, variable salinity, acidified and eutrophic estuarine bay (Brunei Darussalam, northwest Borneo). We present records for 14 morphological species (OTUs). Six of these species belong to the Haplosclerida, an order of shallow-water sponges that usually tolerate more variable and extreme physical conditions. Our baseline data contribute to the regional biogeography of sponges and present a reference source for ecological studies on marine animals inhabiting variable estuarine environments. This is the first known record of sponges from the northwest Bornean region of the South China Sea that are not associated with a coral ecosystem; other studies have concerned Singapore, peninsular Malaysia, Thailand, Cambodia, Vietnam, southern China, and Taiwan.

Background and objectives

The fact that metabolism and immune function are regulated by an endogenous molecular clock that generates circadian rhythms suggests that the magnitude of ischemia reperfusion, and subsequent inflammation on kidney transplantation, could be affected by the time of the day.

Design, setting, participants, & measurements

We evaluated 5026 individuals who received their first kidney transplant from deceased heart-beating donors. In a cause-specific multivariable analysis, we compared delayed graft function and graft survival according to the time of kidney clamping and declamping. Participants were divided into those clamped between midnight and noon (ante meridiem [am] clamping group; 65%) or clamped between noon and midnight (post meridiem [pm] clamping group; 35%), and, similarly, those who underwent am declamping (25%) or pm declamping (75%).

Results

Delayed graft function occurred among 550 participants (27%) with am clamping and 339 (34%) with pm clamping (adjusted odds ratio, 0.81; 95% confidence interval, 0.67 to 0.98; P=0.03). No significant association was observed between clamping time and overall death-censored graft survival (hazard ratio, 0.92; 95% confidence interval, 0.77 to 1.10; P=0.37). No significant association of declamping time with delayed graft function or graft survival was observed.

Conclusions

Clamping between midnight and noon was associated with a lower incidence of delayed graft function, whereas declamping time was not associated with kidney graft outcomes.
EVALUATION OF LOGISTIC FLOWS IN GREEN SUPPLY CHAINS BASED ON THE COMBINED DEMATEL-ANP METHOD
Authors: Osintsev Nikita , Rakhmangulov Aleksandr , Baginova Vera
Published: October 2021

Supply chains and transport corridors have a significant impact on the socio-economic and environmental situation in the regions where the elements of the logistics infrastructure are located. The achievement of the goals of the concept of sustainable development in these regions is ensured, among other things, as a result of the formation of green supply chain management (GSCM), that is, as a result of changes in existing approaches to supply chain management. Analysis of the practice of supply chain management showed a wide variety of parameters and indicators of logistics flows used in decision-making at different stages of managing these flows. The authors propose a universal system of the logistic flows parameters and indicators for the GSCM, corresponding to the principles of the concept of sustainable development. A methodology for ranking indicators of logistics flows based on a combined DEMATEL-ANP method has been developed. The results of a case study on the evaluation of logistics flows for the GSCM are presented. The ranks of logistics flow indicators obtained in the study are proposed to be used in GSCM to adjust of the logistics flows actual parameters to achieve the goals of the concept of sustainable development.

Authors: Momberg Uribe Rodrigo
Published: October 2021

Chilean legal doctrine has not studied well enough the relationship between the fine’s regime set up by the Chilean Consumer Rights Act (Law N° 19,496, 1997) and its application to economic activities regulated by special legislation. This paper has the purpose to analyze the problems related to that relationship. With this objective, the paper makes a distinction between the three cases where the Law N° 19,496 applies to economic activities regulated by special legislation, in conformity with article 2 bis of the Law N° 19,496.
Sensibilidad victoriana, cuerpos mexicanos: El arte de Adela Breton
Authors: Méndez Adriana
Published: October 2021

Los numerosos viajes de Adela Breton a México, iniciados en 1893, trazan un itinerario de gran complejidad y relieve emotivo. La sensibilidad apasionada de esta artista-viajera se desata en México más que en ningún otro sitio; el arte pictórico de Adela Breton muestra el anhelo de captar la poesía del paisaje, el perfil de sus pueblos y las huellas del pasado con una mirada atenta a la curiosidad arqueológica o a la ruina olvidada. Es indudable que el lugar que ocupa Adela Breton dentro de la tradición de la literatura de viajes es el de exploradora visual.
Adaptación, interpretación, escritura: Los horizontes del texto literario. La traducción también un problema de filosofía

¿Hay aún algo que decir, algo que no ha sido dicho, sobre la traducción? ¿Algo que no sólo explicase técnicamente lo que la traducción es, sino algo que vinculándola con otros haceres humanos, con la esencia del hacer humano incluso, nos permitiese dar cuenta de lo que somos o aspiramos a ser? Me refiero a si habría algo que decir sobre la traducción que nos condujera más allá de las respuestas de la moderna ontología, lamentablemente presa de un cierto romanticismo del espíritu.
Flaying the Image: The Body of the Anatomicatomical Theatre in Purview of Walter Benjamin's Work on Allegory and the Baroque
Authors: Pardo-Domínguez Yaocí
Published: October 2021

The Baroque coincides with the development of a new art, a technique that learned how to read the confessions of the body, one that knew with precision how to bring the body out of its deadly silence and make it confess. This was not the tribunal of the Inquisition; this was the Anatomy theatre whose imprint bore the character of the scalpel. By laying out the canvas of the corpse, the amphitheatres showed a figure appearing upon the very same folds under which it disappeared. In the anatomy lesson, the act of reading coincided with an act of writing: the knife wrote as it read. The anatomist conceived a carte blanche, a blank map whose contours were traced on the selfsame edges of the parchment. For the first time—it seemed—the portent of veils gave straight answers. The magistri vulnerum—the masters of wounds—sought to undo the body in order to gaze at the nakedness of Eden; their most prized text being the silence written on Adam’s coat of skin. Such was the dream of the anatomist: to hold the image of man in one piece. Piece by piece

A novel and robust technique for identifying prestress forces in prestressed concrete beams using generic finite elements and simulated annealing algorithms
Authors: Cruz A. , Vélez W. , Thomson P.
Published: October 2021

This work presents a novel technique for estimating the prestressing forces in simply supported beams with axial prestress force. The technique is based on the use of generic finite elements for modeling the beam and experimental time-domain response to simultaneously identify axial forces and generic parameters. Parameter updating is accomplished using a Simulated Annealing algorithm implemented for the solution of the prestress force identification problem. The effectiveness of the method was assessed in numerical simulations and was further verified on an experimental prestressed concrete beam. The results show that the inclusion of generic elements allows the identification of the force to be achieved even in the presence of errors in model parameters, thus eliminating the restraints of previous approaches.
A multi-item manufacturing system with an outsourcer and random defective items
Authors: Chiu Yuan-Shyi Peter , Jhan Jia-Hang , Chiu Victoria , Chang Huei-Hsin
Published: October 2021

This study examines a multi-item manufacturing problem with a single machine, an outsourcer, and random defective items. To cope with the increasing multi-product demands from global markets, modern manufacturing firms must make an efficient production plan to satisfy customer’s needs with quality goods and smooth the in-house fabrication schedule and utilization. Outsourcing is an effective option to avoid machine overloads and smooth fabrication schedules. Further, the fabrication of random defective products is inevitable because of unanticipated factors in real manufacturing environments. These products must be identified, separated and discarded to retain the desired quality of the finished lot. To address the above-mentioned concerns, this study develops a mathematical model to represent a hybrid stock refilling system, employs mathematical derivations to find long-run average system expenses, and uses an optimization technique to derive a closed-form common rotation time for this hybrid system. The results of this study show the individual and combined impacts of variations in outsourcing percentages and scrap rates on optimal rotation time and diverse core system parameters (such as machine utilization, specific cost component, etc.) to facilitate planning, controlling, and decision making in such a particular hybrid fabrication system.

Published: October 2021

Osteomyelitis associated with periprosthetic joint infection (PJI) signals a chronic infection and the need for revision surgery. An osteomyelitic bone exhibits distinct morphological features, including evidence for osteolysis and an accelerated bone remodelling into poorly organised, poor-quality bone. In addition to immune cells, various bone cell-types have been implicated in the pathology. The present study sought to determine the types of bone-cell activities in human PJI bones. Acetabular biopsies from peri-implant bone from patients undergoing revision total hip replacement (THR) for chronic PJI (with several identified pathogens) as well as control bone from the same patients and from patients undergoing primary THR were analysed. Histological analysis confirmed that PJI bone presented increased osteoclastic activity compared to control bone. Analysis of osteocyte parameters showed no differences in osteocyte lacunar area between the acetabular bone taken from PJI patients or primary THR controls. Analysis of bone matrix composition using Masson’s trichrome staining and second-harmonic generation microscopy revealed widespread lack of mature collagen, commonly surrounding osteocytes, in PJI bone. Increased expression of known collagenases, such as matrix metallopeptidase (MMP) 13, MMP1 and cathepsin K (CTSK), was measured in infected bone compared to non-infected bone. Human bone and cultured osteocyte-like cells experimentally exposed to Staphylococcus aureus exhibited strongly upregulated expression of MMP1, MMP3 and MMP13 compared to non-exposed controls. In conclusion, the study identified previously unrecognised bone-matrix changes in PJI caused by multiple organisms deriving from osteocytes. Histological examination of bone collagen composition may provide a useful adjunct diagnostic measure of PJI.

Stress as a Workload in Intensive Care Units
Authors: Zacharova E. , Moltasova K. , Kyasova M.
Published: October 2021

Stress is one of the significant workloads in intensive care units. This survey examines the relationship between the level of stress experienced, gender, age, length of practice and the degree of the workplace. It maps the factors that lead to the emergence of stress in intensive care units and examines its impact on work performance. Results from 121 respondents working in intensive care units show that the level of stress correlates with age and is typical for certain stages of life. Work stress is mostly created by load, where the physical and mental component is applied. Total physical activity corresponded to moderate load and the most important physical factors represented increased demands on the musculoskeletal system and disturbance of sleep rhythm. The level of mental stress was also in the moderate values. The most important psychologicalstressors were identified as a high degree of responsibility and increased demands on cognitive functions
“Possible Worlds” and the Meanings of F. Dostoevsky's Providence in the Messianic Receptions of the ХХth Century
Authors: Garipova Gulchira T.
Published: October 2021

The article analyzes the specifics of the receptive impact of the artistic Messianic concept of F. Dostoevsky, which influences providential contexts in the cultural philosophy of the ХХth century. The possibility to identify the features of the artistic embodiment of the Russian Messianic problems in cultural philosophy and literature of the ХХth century determines the relevance of this study. The analysis of the strategy of modeling possible worlds in Dostoevskys work, which referentially determines the development of Russian utopian / dystopian providence, determines the novelty of the study. The concepts of the Christological axiosphere, which reflects Dostoevsky's Messianic concept, determine the most important coordinates of the providential receptive trends of the ХХth century. They are objects of analysis in the article. It is proved that the semiotics of messianic motifs in Russian literature of the XXth century is connected, first of all, with the Abrahamic religious context, which is built into the most complex providential concept of the anthropological Christology of F. Dostoevsky. According to the principles of fractal logic, the writer generates the Abrahamic canon in the key messianic world-modeling metametaphors. Dostoevsky's messianic pretext is referentially manifested in Russian literature of the twentieth century - in the work of Russian Symbolists, who understand the Messiah as a divine-existential personality, in the works of writers of the late XXth century, who interprete the messiah as a collective personality - a substitutionary sacrifice. In our opinion, the chiliastic aspiration of messianic Christology and anthropology is also connected with the influence of Dostoevsky. However, we should talk about the dissipative variability of messianic concepts due to the contextual reference of messianic ideas of eastern origin, in particular, the Zoroastrian, Sufi and Islamic contexts are found. The artistic idea of messianism in Russian literature of the XXth century can also be considered as a semiotic sign system that reveals historiosophical and socio-political meanings, modeling the tendencies of anthropologization and ontologization of the literary process.
Dostoevsky in Kazakhstan: History of Study, Results, Prospects
Authors: Matyzhanov Kenzhekhan Slyamzhanovich , Ananyeva Svetlana V.
Published: October 2021

The article is devoted to the analysis of the Semipalatinsk and Kuznetsk periods in the life and work of F.M. Dostoevsky. The purpose of the study is to reveal the Kazakh-Siberian periods in the fate of the Russian writer, their reflection in the letters and works of art by F.M. Dostoevsky. In the year of the 200th anniversary of the birth of the Russian writer, we cannot talk about the complete study of the indicated periods of the life of the prose writer, which, of course, to one degree or another, were reflected in his prose. This determines the degree of novelty of this article. Dostoevsky is dear to Kazakhstan. He not only served his exile, but also found a friend here, sincere and quivering - the historian, orientalist, ethnographer Ch. Valikhanov. The stories Uncle's Dream and The Village of Stepanchikovo and Its Inhabitant, the first chapters of Notes from the Dead House were written in Semipalatinsk. The story The village of Stepanchikovo and its inhabitants (1857-1859) has the author's clarification: From the notes of the unknown. Many works of fiction in world literature are the result of travel notes, diaries. Undoubtedly, the restoration of the history of the Kazakh-Siberian period of the life and work of F.M. Dostoevsky is of great value, because the greatest Russian writer experienced spiritual revival there, in Kazahstan. The works of F.M. Dostoevsky were included in the literature program of secondary schools in Kazakhstan, translated into Kazakh ( The Idiot, The Brothers Karamazov translated by N. Syzdykov). Dostoevsky scholars of Kazakhstan in the XXI century continue to study the writers works.
Oblomov and Myshkin: Some Aspects of the Issue
Authors: Belyaeva Irina A.
Published: October 2021

The article examines one of the possible parallels between the protagonists of the novels Oblomov and The Idiot , which was formulated by Dostoevsky himself. He pointed out both the similarities between Myshkin and Oblomov and the differences between the two. The purpose of the article is to explain the special status of the characters of Dostoevsky and Goncharov, which is linked to their explicit or implicit desire to save the world. The task is to systematize various views of scholars on the issue of Dostoevsky and Goncharov, especially in the light of their relation to the Russian spiritual tradition. The thesis is put forward that the similarity between the two protagonists may be explained by the similarity of the two authors views on the problem of secular holiness. In both novels similar versions of the plot of salvation are realized, in which the protagonist claims to be the savior of others, although another motif, that of personal salvation, is emphasized by Goncharov in Oblomov and has Dante origins. While in the case of Myshkin his wish to be Christ-alike lead him to a personal catastrophe, and the destruction of his inner circle, in Oblomovs case there are no such losses, there are even some advantages in the form of the emerging life of Shtolz and Olga, in the form of awakening to a new life of Agafia Matveevna Pshenitsyna. The author of the article comes to the conclusion that both Dostoevsky and Goncharov did not forget about the human nature of their characters, but the former, as Goncharov put it, allowed his Myshkin, Prince Christ, to wear a divine robe and thus largely predetermined his failure as a savior, while the latter alleviated the traits of holiness in his Oblomov, leaving only traces of them, which attract people to the character making them and their small world better.
Notes from Underground by F.M. Dostoevsky in XXth Century English Criticism
Authors: Markova Ekaterina A.
Published: October 2021

The article is devoted to the issue of the critical reception of F.M. Dostoevskys Notes from Underground in the XXth century. Some letters, as well as books on philosophy and literary criticism by such writers as D.H. Lawrence, J.M. Murry, C. Wilson and I. Murdoch are analysed. The reviews by the given authors correspond to two waves of interest in Dostoevsky - the first one took place at the turn of the XXth century followed by the second one in the middle of the century. The writers name the key characteristics of the Underground Man: vanity, egoism, self-division, desire for suffering and inability to act. Some critics of Dostoevskys Notes see the Underground Man as recurrent image and note his relevance to the ideas of existentialism, especially the one about inability to apprehend truth in a rational way.
Conflict as a Category of Literary Studies: Analytical Research Strategies
Authors: Khomyakova Olga R.
Published: October 2021

The substantiation of the methodological viability and hermeneutic potential of the category conflict is given. The role of conflict as a category of world modeling in fiction is pointed out. Consideration of the conflict in the aspect of dialogism is suggested. Conflict in fiction is a special kind of communicative act arising from the antagonism of misunderstanding of the opposing sides, but providing a new level of understanding to the perceiving consciousness of the reader, making it intellectually armed (R. Jacobson) in the face of conflicting structures. Analytical strategies for the study of conflict are presented in the semantic aspect (conflict as an object of artistic depiction) and the aspect of structure (conflict as a fundamental structural principle). It is proved that the dual nature of the conflict presupposes taking into account in research practice the possibilities of textocentric and anthropological approaches to the study of conflict, understood as antagonistic relations of oppositional units. The development of epistemology, axiology and poetics of conflict in fiction is seen in the way of studying all levels of conflict dialogue.
Positivism in the Mirror of Carnival: The Rabelaisian Chronotope in the Works of E. Zola
Authors: Albrekht Olga V.
Published: October 2021

This paper deals with using the Rabelaisian cultural code, which the author of the article suggests to be applied to the reading and interpreting of some novels by E. Zola. From the authors point of view, such an experiment allows us to look at French naturalism from a new point of view, as a variant of a typologically recurring phenomenon in the history of literature. For the French naturalistic novel Rabelaisianism is considered as a kind of meaning-generating model, as appropriated communication or as an element of traditional literary discourse. The latter is actualized in a period when the cultural conditions and the nature of the main ideological and aesthetic conflicts became similar to the time of the French Renaissance. The author attempts to apply the theory of the carnival chronotope, which is developed by M.M. Bakhtin, to the interpretation of some of E. Zolas texts. Meanwhile, the concept of the chronotope is considered more widely than that of M.M. Bakhtin: it is proposed to understand the chronotope as a universal model of space-time relations in the novel. The author also views the poetics of the real in the naturalistic novel through the prism of the carnival (i. e. extremely detailed material world); as examples, the motives of food and wine, as well as the motive of rebellion and war as a variant of the war for food and the carnival battle of Shrovetide (pancake week) and Lent are analyzed in the article. The main material used for the analysis is taken from the novels Le Ventre de Paris , 1873 ( The Belly of Paris ), LAssommoir , 1877 ( The Trap ), and Germinal , 1885, by E. Zola.

Estereótipos associados à religiosidade afro-brasileira nas narrativas jornalísticas cariocas na década de 1920
Authors: Souza Ronivaldo Moreira de , Ribeiro da Silva Mauricio
Published: October 2021

Ao longo do processo de formação sócio-histórica do Brasil, os colonizadores construíram narrativas com imagens estereotipadas dos africanos escravizados e de sua religiosidade a partir de uma visão europeia e cristã. Mesmo depois da abolição da escravidão esses estereótipos permaneceram associados à religiosidade afro-brasileira e foram apropriadas pelas narrativas jornalísticas, contribuindo para reverberar essa estereotipia até o tempo presente. O objetivo deste artigo é analisar os estereótipos associados à religiosidade afro-brasileira na década de 1920 nas narrativas jornalísticas da imprensa carioca. Tendo como base os pressupostos teórico-metodológicos da Análise do Discurso de Escola Francesa, compomos o corpus da pesquisa com 24 textos, dos quais, dois são tomados para análise no artigo e considerados como representativos da seleção. Constatamos que nas narrativas analisadas a religiosidade afro-brasileira é demonizada, configurando a estereotipia.
O novo coronavírus e a condição da banalidade do mal
Authors: Amaral Muriel Emídio Pessoa do
Published: October 2021

A proposta deste artigo é reconhecer o sentido da banalidade do mal, desenvolvido por Hannah Arendt (1999), em acontecimentos contemporâneos ocorridos no Brasil durante a pandemia do novo coronavírus. De acordo com a autora, o mal é banal porque é praticado por pessoas convencionais que se abstiveram de pensar politicamente. A partir dessa ideia, por meio da análise de matérias jornalísticas divulgadas pelo site Catraca Livre, o artigo apresenta reflexões sobre as manifestações contra a quarentena e isolamento social e físico sugeridos pela Organização Mundial da Saúde (OMS) para conter o avanço da doença. As manifestações ocorreram na cidade de São Paulo e ainda apoiaram a figura do presidente brasileiro Jair Bolsonaro.
“Transforme-se em você!”: corpo, narrativas e subjetividade em anúncios de cosméticos para mulheres
Authors: Da Costa Oliveira Siqueira Denise , De Siqueira Euler David
Published: October 2021

O artigo estuda o fenômeno da subjetivação nas narrativas publicitárias de cosméticos para mulheres da empresa Salon Line. Mobiliza as categorias corpo, gênero, subjetividade e consumo como construções sociais. Trata-se de pesquisa exploratória, um estudo de caso desenvolvido a partir de amostra qualitativa por escolha, orientado por abordagem epistemológica compreensiva. A questão discutida diz respeito a como tais narrativas sugerem que a consumidora se individualize, introjetando, no entanto, uma norma que na realidade é exterior. Resultados preliminares deixam entrever que a suposta autonomia presente na publicidade omite o intricado processo de interiorização de normas exteriores.
Do cientista e sua (des)legitimação: Atila Iamarino e o contexto do Coronavírus no Brasil em 2020
Authors: Ramos de Almeida Gabriela Machado , Bezerra dos Santos Danielly
Published: October 2021

Neste texto, partimos das apreciações conceituais da pós-modernidade propostas por Jean-François Lyotard (2020) para observar e discutir a posição de legitimidade do cientista enquanto especialista envolvido na chamada ‘crise da expertise’ contemporânea, apresentada pelo autor Gil Eyal (2019). No percurso, refletimos brevemente sobre as principais mudanças na formação da ciência moderna, a ocorrência da pós-modernidade e a tensão nas relações de especialização. O material empírico se refere a uma série de comentários negativos a uma postagem opinativa do biólogo brasileiro Atila Iamarino na rede social Twitter, em junho de 2020. Na avaliação sobre quais elementos são evidenciados por usuários críticos ao cientista, as análises demonstraram a ausência de argumentos por parte dos opositores e a resistência ao uso de uma argumentação científica totalizante, com críticas não ao trabalho, mas à pessoa do cientista.
Conspiracionismo e negacionismo político-midiático: complementaridades discursivas entre Bolsonaro e Sikêra Júnior sobre a pandemia de Covid-19
Authors: Malerba João , Fernandes Rosangela
Published: October 2021

O estudo investiga articulações político-midiáticas em favor de uma narrativa comum sobre a pandemia de Covid-19 baseada em teorias conspiratórias e negacionistas e pautada em discursos populistas e de ódio. A análise tem como foco vídeos sobre a pandemia do apresentador do programa policialesco Alerta Nacional, Sikêra Júnior. Os resultados apontam para uma lógica de complementaridade entre o comunicador e o discurso do presidente Jair Bolsonaro, em uma estratégia comunicativa que integra mídia hegemônica e redes sociais como forma de potencializar a disseminação de desinformações, além de trazer indícios de relações que preservam as raízes clientelistas do sistema de comunicação brasileiro.

Purpose: Genital injury is a common pediatric injury. Given the lack of nationwide data, the authors aimed to show age group-related epidemiologic features of genital injury in Korea.Methods:We reviewed the data from 2011-2016 Emergency Department-based Injury In-depth Surveillance registry, which involves 23 emergency departments in Korea. From the dataset, we included children (< 18 years) with the International Classification of Diseases, 10th Revision codes related to genital injury as the final diagnosis with excluding those with other codes or combined injuries. Age groups were defined as follows; infants (< 1 year), toddlers (1-3), preschoolers (4-6), schoolers (7-12), and adolescents (13-17). The clinical features and outcomes were analyzed.Results: A total of 3,030 children were included with the median age of 6 years (interquartile range, 4-10) and the proportion of girls of 53.0%. Only 144 children (4.8%) were transported by the emergency medical service providers. The most common mechanism and place were blunt injury (1,826 [60.3%]) and home (1,535 [50.7%]), respectively. Of the codes, “Contusion of external genital organs (S30.2)” was most common (1,574 [51.9%]). As for outcomes, 2,770 children (91.4%) were discharged, 252 (8.3%) were hospitalized (intensive care units, 1 child [0.03%]), and 108 (3.6%) underwent surgery. Severe injury occurred in 111 children (3.7%) without a mortality. With increasing age in the age groups, non-accidental injury, school and sports-related injuries, hospitalization, and surgery (All Ps < 0.001).Conclusion: Genital injury may occur at evening, in spring and summer, at home, and in the form of accidental or blunt injury. Most children are discharged. Contrary to these general features, older children tend to undergo more frequently non-accidental injury, school and sports-related injuries, hospitalization, and surgery. Thus, we need age-specific strategies for injury prevention.
REPUBLIC OF THE OTHER

Published: October 2021

REPUBLIC OF THE OTHER is an art collective consisting of and founded by Jinny Yu and Xenia Fink.
A contradiction in itself, REPUBLIC OF THE OTHER reflects our questioning of geographic and national identities defined by borders and boundaries and is the basis of our research on the attraction to form an entity.
Our collaboration started with the urgency to express our resistance against the generalized right-wing tendency, with nation-states and borders strengthening with great force worldwide and with the conviction that we have something to contribute to the discussion.
Manifestos as a subject matter are our way to describe a utopia where we all accept each other as an “other”.
Our practice is executed through exchanging and developing ideas from our respective locations. Remotely sharing thoughts naturally lend to working with text as a medium; when we occasionally do convene, concepts may also take the shape of installations and video work.
Rapid evolutionary divergence of a songbird population following recent colonization of an anthropogenic habitat
Authors: Friis Guillermo , Atwell Jonathan , Fudickar Adam , Greives Timothy , Yeh Pamela , Price Trevor , Ketterson Ellen , Milá Borja
Published: October 2021

Colonization of a novel environment by a few individuals can lead to
rapid evolutionary change, yet evidence of the relative contributions of
neutral and selective factors in promoting divergence during the early
stages of colonization remain scarce. We explore the role of neutral and
selective forces in the divergence of a unique urban population of the
dark-eyed junco (Junco hyemalis), which became established on the campus
of the University of California at San Diego (UCSD) in the early 1980s.
Previous studies based on microsatellite loci documented significant
genetic differentiation of the urban population as well as divergence in
phenotypic traits relative to nearby montane populations, yet the
geographic origin of the colonization and the factors involved remained
uncertain. Our genome-wide SNP dataset confirmed the marked genetic
differentiation of the UCSD population, and we identified the coastal
subspecies pinosus from central California as its sister group instead
of the neighboring mountain population. Demographic inference recovered
a separation from pinosus as recent as 20 to 32 generations ago after a
strong bottleneck, suggesting a role for drift in genetic
differentiation. However, we also found significant associations between
habitat variables and genome-wide variants linked to functional genes,
some of which have been reported as potentially adaptive in birds
inhabiting modified environments. These results suggest that the
interplay between founder events and selection may result in rapid
shifts in neutral and adaptive loci across the genome, and reveal the
UCSD junco population as a case of contemporary evolutionary divergence
in an anthropogenic environment.

The presence of single nucleotide variations in the coding region of micro-RNA (miRNA)-encoding genes plays a significant role in the expression and function of these molecules in oncogenesis and cancer. The association of rs2682818 in miR-618 with increased risk of breast cancer was investigated in the Iranian population. rs2682818/miR-618 was genotyped using amplification-refractory mutation system PCR (ARMS-PCR) in 200 healthy individuals and patients with breast cancer. The data revealed the presence of Hardy-Weinberg equilibrium (HWE) for this marker. The frequency of alleles C and A was 70% and 30%, respectively, in healthy individuals; the frequency of alleles C and A was 44% and 56%, respectively, in patients with breast cancer. Analysis of odd ratios showed that the rs2682818/miR-618 polymorphism is associated with increased probability of breast cancer and is statistically significant (OR=2.97, P=0.0003). The data suggest that rs2682818/miR-618 could be considered a novel marker of increased risk of breast cancer.

Middle Miocene otoliths of freshwater fishes from the Vracevic Lake (Serbian Lake System)
Authors: Bradic-Milinovic Katarina , Rundic Ljupko , Schwarzhans Werner
Published: October 2021

The Serbian Lake System (SLS) is a key area for early to middle Miocene freshwater environments in southeastern Europe. Here, we describe a rich fossil association of freshwater fish otoliths of late Badenian to early Sarmatian (Serravallian, MN 7+8 zone) age. The studied material was collected from several small outcrops along the Grabovac stream near Vracevic. The Vracevic locations are part of the Valjevo?Mionica Basin (VMB). We identified nine different species, including two in open nomenclature and three new to science: Aphanius jeani, Aphanolebias bettinae n.sp., Klincigobius andjelkovicae, Klincigobus haraldahnelti n. sp., Klincigobius serbiensis, Klincigobius sp., Ponticola sp., Toxopyge campylus, Toxopyge vracevicensis n.sp. We found that the composition of this fish fauna correlates well with the slightly older fauna from the early to middle Miocene of Klinci. Both localities were most likely part of a continuous environment during the existence of the Valjevo?Mionica Basin. The composition of the community of freshwater gobies from the early to early middle Miocene of southeastern Europe indicates the presence of a ?lost? Miocene freshwater goby fish fauna that existed prior to and was unrelated to the Ponto-Caspian fish fauna that prevails today. The new data may prove to be helpful in reconstructing the paleogeographical evolution of the Valjevo?Mionica Basin in detail.
Facile preparation of ZrO2 whiskers by LiF-KCl molten salts synthesis
Authors: Zhang Quan , Feng Guo , Jiang Feng , Liu Jianmin , Miao Lifeng , Wu Qian , Wang Tao , Jiang Weihui
Published: October 2021

Monoclinic zirconia (ZrO2) whiskers were made via the molten salt method
using zirconyl chloride octahydrate (ZrOCl2 ? 8H2O) as zirconium source,
potassium chloride (KCl) as molten salt and lithium fluoride (LiF) as a
mineraliser. DSC-TG, XRD, FE-SEM, Raman and TEM were performed to study the
effects of heat treatment temperature, holding time and heating rate on the
synthesis of zirconia whiskers. The results indicate that zirconia whiskers
with diameters of 50-80 nm and aspect ratios of 10-30 can be obtained by
heating the precursor at slow rate (3?C/min) to 718?C for 1 h and then at
faster rate (7?C/min) to 950?C for 3 h. The whiskers have a smooth surface
and grow in [001] direction. The key to the ZrO2 whiskers growth is the
controlled dissolution and precipitation of the ZrO2 in a LiF-KCl molten
salt solution environment.
The effect of lanthanum addition on the microstructure and mechanical properties of Mg-modified hydroxyapatite ceramics

In the present paper, the effect of La2O3 (0.25, 0.5 and 1 wt.%) addition on
the phase stability, porosity, density, hardness, fracture toughness,
compressive strength and brittleness index of hydroxyapatite modified with 1
wt.% of MgO was investigated. Hydroxyapatite (HA) without additives sintered
at 1300?C has mixture of dominant hydroxyapatite phase with beta-tricalcium
phosphate (?-TCP), alpha-tricalcium phosphate (?-TCP) and calcium oxide
(CaO) phases. The microstructure is characterized with transgranular
microcracks and oversized grains. Although the density and hardness of the
pure HA increased with increasing temperature, a steady decrease in fracture
toughness (from 0.96 to 0.71MPa?m1/2) and compressive strength (from 130.2
to 65.6MPa) was observed. For the HA modified with 1 wt.% of MgO the highest
compressive strength (183.2MPa) and fracture toughness (1.47MPa?m1/2) were
obtained at 1200?C and at this temperature the brittleness index was 3.24
?m-1/2. Increase in the sintering temperature led to the increase of the
brittleness index of the pure HA,MgO modified HA and La2O3-MgO modified HA
samples. The addition of 1 wt.%La2O3 to 1 wt.% MgO-HA contributed to the
increase in the compressive strength of about 10%(from 183.2 to 202.0MPa),
fracture toughness of about 69% (from 1.37 to 2.32MPa?m1/2) and also
decrease of the brittleness index from 3.24 to 2.18 ?m-1/2. The best
performance after sintering at 1300?C was obtained for the MgO-HA sample
with 0.25wt.% La2O3. As a result of this study, a new candidate material for
biomedical application with superior mechanical properties and the phases
that do not cause adverse reactions in the human body could be 1 wt.% MgO-HA
modified with 1 wt.% La2O3 and sintered at 1200?C.
Thermophysical performances of (Sm1-xLux)3TaO7 (x = 0, 0.1, 0.3 and 0.5) ceramics
Authors: Sang Weiwei , Zhang Hongsong , Chen Huahui , Wen Bin , Li Xinchun , Li Mengwei
Published: October 2021

To optimize thermophysical performances, Sm3TaO7 was doped with Lu3+ and
pressureless sintered at 1600 ?C. It was shown that Sm3+ is partly
substituted by Lu3+ cations and the (Sm1-xLux)3TaO7 ceramics with a single
pyrochlore structure are obtained.With increasing x value from 0 to 0.5, the
band gap increases gradually from 4.677 to 4.880 eV. Owing to the enhanced
phonon scattering caused by Lu3+ doping, the thermal conductivities at 800
?C of the prepared samples are in the range of 0.95-1.44W?K?1?m?1. It was
also confirmed that the phase transition is restrained effectively by
substituting Sm3+ with Lu3+. Due to the reduction of crystal lattice energy
and average electro-negativity difference, the thermal expansion coefficient
(TEC) is heightened with increasing Lu content. TEC achieves the highest
value (10.45 ? 10?6 K?1 at 1200 ?C) at the equal molar ratio between Sm3+
and Lu3+ cations (i.e. x = 0.5), which is much higher than those of 7YSZ and
Sm2Zr2O7 ceramics.
