Out of the mainstream. Henryk Weber – a Jewish art critic in interwar Cracow
Authors: Wasilewska Diana
Published: January 2020

Henryk Weber, a painter and art critic of the interwar period, is today a completely, though
inequitably, forgotten fi gure. He was mainly associated with the Jewish magazine „Nasz Wyraz”
in which he ran a column devoted to the visual arts. He was particularly interested in the history
of the artistic milieu of Cracow, including, though not exclusively, Jewish artists. As a painter he was
close to the colorists, and in his reviews he turned out to be an insightful observer and interpreter,
also open to the latest avant-garde art phenomena. His artistic concept grew out of the expressionist
aesthetics, treating art as an expression of the artist’s feelings and emotions, but the act
of creation meant for him submitting these impressions to the laws of a strict logical construction.
Weber’s statements, especially reviews, are characterized by an extraordinary suggestiveness of the
language, which is a specifi c combination of professional terminology and colloquialisms or terms
borrowed from other disciplines or areas of life. Aesthetic and linguistic awareness, wide knowledge
of the latest artistic phenomena as well as openness to new artistic trends make him one of the most
outstanding critics of the interwar period in Poland.
The bodies of Zuzanna Ginczanka
Authors: Kumala Aleksandra
Published: January 2020

The article focuses on the representations of the body in Zuzanna Ginczanka’s poetry. There
are four crucial poetic constructions in this respect that need to be properly contextualized:
the Jewish body (Ginczanka’s beauty and stigma, her legendary eyes), the lyrical body (the feminine
origin of her poetry, its erotic, emancipatory character, the meaning of victim and revenge
themes), the individual and the social body (the ways of shaping her identity and some of her key
performative gestures), and, fi nally, the visual body (the poet’s public image in the past and now).
Aside from Bożena Keff’s and Agata Araszkiewicz’s discussions of Jewishness in Ginczanka’s poetry,
the article refers to Erving Goffman’s, Jean-Paul Sartre’s and Richard Schechner’s theories to illuminate
the complex mechanisms behind Zuzanna Ginczanka’s ambiguous position in the literary and
cultural discourse through the years.
Everydayness and Religiousness at the Intersection of Epochs
and Cultures: Wierszalin. Reportaż o końcu świata (Wierszalin. A Report
on the End of the World) by Włodzimierz Pawluczuk and Piotr Tomaszuk
Authors: Nalewajk Żaneta
Published: January 2020

The article discusses the production of Wierszalin. Reportaż o końcu świata (Wierszalin.
A Report on the End of the World) by Włodzimierz Pawluczuk, an anthropologist
and religious studies scholar, which was prepared by Piotr Tomaszuk in the theatre
Wierszalin. The analysed text depicts events that took place during World War I and in
the 1920s and 1930s near the town of Białystok (the rise of specifi c chiliastic communities).
The article’s particular focus is a paradoxical situation when the need to bless the
acts of everyday life, poignantly experienced due to the awareness of the approaching
“end of the days”, easily borders on fraud and the need to infl uence the fate of the community,
in a word, with the striving for power.
Intercultural Disidentifications in Theory, and in Poetic and Theatrical Practice
Authors: Welizarowicz Grzegorz
Published: January 2020

Taking Chicano poet Tino Villanueva’s collection Scene from the Movie GIANT (1993) as an opening example the essay looks at the strategies available to a subject at a moment of an unequal intercultural encounter, that is when the discourse of the dominant culture is experienced as exploitation or exclusion. Building on Louis Althusser’s theory of Ideological State Apparatuses (ISA) and on Michel Pêcheux’s linguistic reading of ISA as discursive formations it is proposed that Villanueva’s poetry exemplifi es a type of relationship of a subject to the dominant formation which Pêcheux calls “Disidentifi cation”. Pêcheux’s theory of subjecthood is discussed in detail. It is then applied in an interpretation of two excerpts from Chicana performer/dramatist Monica Palacios’ oeuvre. The essay concludes with a proposition that “disidentifi cations” offer an important tool of maintaining a fl uid and ambivalent type of subjectivity in the times of the „death of the subject” and intercultural crises. Disidentifi catory practices, by reworking our epistemic certainties, may lead the way in building sustainable pluralistic humanism.
On Intercultural Theatre
Authors: Pavis Patrice
Published: January 2020

The article gives an account of the current state of research on intercultural theatre.
It seems that we have moved away from the polemics of the 1980s about intercultural
theatre, and that interculturalism has been often replaced by a globalized theatre.
The aesthetics, ethics and politics have changed and we are now faced with very different
problems and also different kinds of globalized performances.
From „neither this nor that” to „a stereoscopic and stereophonic attitude to the world”: writers’ attitude to bilingualism
Authors: Kubińska Olga
Published: January 2020

The article examines the problem of bilingualism from a diachronic perspective in the context of the contribution of current cultural theories (gender, postcolonial) to the perception of multilingualism in contemporary culture. A distinct issue in this research is compulsory bilingualism caused by the Holocaust and involuntary resettlement processes resulting from political harassment. The article also emphasizes the import of cultural anthropology, cognitive sciences and the sociology of translation into the redefi nition of the very notion of bilingualism and the infl uence of this phenomenon on such remote from literature spheres as therapy. Refl ection on bilingualism is largely dependent on the intellectual capacity of the bilingual authors conducting self-analysis. The cases of Eva Hoffman and Anna Wierzbicka provide more than adequate evidence which signifi cantly complements the testimony of philosophers, such as trilingual George Steiner, and bilingual writers, such as Conrad, Nabokov or Brodsky. Finally, it should be added that globalization favors bilingualism among authors but often also provides the rationale for choosing a less popular language as a means of expression.
Contemporary Afrikaans Fiction in the World: The Englishing
of Marlene van Niekerk
Authors: Attridge Derek
Published: January 2020

Many of the most ambitious and important South African novels of the past fi fty years have been
written in Afrikaans, but in order to reach a global audience the authors have had to turn to translators. Focusing on Marlene van Niekerk’s novels Triomf (1994; English translation by Leon de Kock,
2000) and Agaat (2004; English translation by Michiel Heyns, 2007), this article examines the challenges that this fi ction, and the particular character and social status of different varieties of Afrikaans,
present to the translator, and discusses the signifi cance of the differences between versions addressed
to an English-speaking South African readership and versions addressed to a global readership. Derrida’s claim that the only thing to be translated is the untranslatable is discussed, and the untranslatability of Triomf and Agaat, it is suggested, also means that they can only be translated and retranslated.
„If you do not believe, look up in here, at my plate”. The Confabulation of Truth
in Curzio Malaparte’s Reportages
Authors: Czardybon Marcin
Published: January 2020

The text concentrates on the war reportages by Curzio Malaparte, an Italian writer, journalist, diplomat and director. They were previously viewed as formally perfect works of reporting,
but presently they provoke controversies, mostly because of considerable modifications of facts and
the inclusion of strongly subjective fragments.
The article is an attempt at capturing the hidden sense of Malaparte’s confabulative text constructions beyond the strategies of autocreation and the author’s striving for commercial success.
The article also deals with an important formal aspect of the reports, namely the issue of the permissible relation between the regimes of Warheit and the order of Dichtung.
The article makes use of the theories of Hans Blumenberg, Hannah Arendt, Klaus Theweleit,
Paweł Zajas, Phillippe Lejeune and others.

The Bread Resolution’s Narrative Shifts
Authors: Kotuła Dominika
Published: January 2020

The article concerns an evolution of interests and views of the members of the Bread Resolution Publishing Hub. The Hub was a Polish online publishing collective, created by Leszek Onak, Piotr Puldzian Płucienniczak and Łukasz Podgórni, which existed from 2011 to 2018. This text traces and analyses the ways in which artistic representations of their ideas and opinions evolved in the light of contemporary theories related to electronic literature. First, the article describes the artists’ initial fascination with the seemingly endless possibilities offered by electronic literature and the Internet, which the Hub’s authors saw as potential sources of a perceptional revolution. Then, an important narrative shift is distinguished – the second part of the text is devoted to the turning point which significantly changed the Bread Resolution’s message. Following this the artists have started to find inspiration in the feeling of being entangled in the socio-economic reality of Poland.
Enacting Embodied Events in Narrative Processing
Authors: Rembowska-Płuciennik Magdalena
Published: January 2020

In this paper, I would like to discuss the status of a particular subclass of events in cognitive narratology: embodied events connected with bodily movements of fictional characters. I will refer to some possible interconnections between current issues in the study of social cognition and the latest debates in narrative studies. I will address opportunities for developing an enactive approach to processing narrative events, with particular reference to the corporeal motion and the concept of bodily simulation. Such an approach could help account for the representation and tracking of events by readers engaged in the embodied experience of reading. I find new approaches to cognition highly inspiring for future research on the intersubjective nature of narrative and for the further development of empirical studies on reader responses to literature.
Lessons from the Dangers of Narrative Project: Toward a Story-Critical Narratology*
Authors: Mäkelä Maria
Published: January 2020

The essay introduces new methods for applied and “story-critical” narratology that are based on the analysis of a crowdsourced corpus in the Dangers of Narrative research project. This analysis suggests that the prototype model of narrative developed by fi rst-wave cognitive narratologists resonates strongly with the popular understanding of what a narrative is and what it can do. Yet, more interestingly, the prototype model also reveals the pitfalls of narrative form in contemporary media. Reliance on individual, unverifi able experience is the most pertinent risk perceived by the informants participating in the crowdsourcing for “dubious” storytelling. The essay also sketches a new theory of viral storytelling spun around the “viral exemplum”, a concept created to describe the viral narrative prototype: a personal “true story” which is given undue representative and normative weight via online sharing.

The aim of the article is to describe the selected features of narrative and to investigate narrative representations in digital environments. By examining the ﬁ gure of implication, non-linearity, narrative as a dual construct (with alleged relations), alternative narrative, and narrative expectation in the digital space, this paper explores the speciﬁ city of digital narrative..
The Romantic Grotesque of George Gordon Byron
Authors: Modrzewska Mirosława
Published: January 2020

The article explores the affi nities between Byron’s works with the seventeenth-century literary tradition of carnivalesque discourse. These affi nities can be traced in his comical burlesque writings, such as The Devil’s Drive (1813), Beppo (1818), The Vision of Judgement (1822) and Don Juan (1819–1824). There is a well-established British critical tradition which sees the author of Don Juan as a continuator of Alexander Pope’s eighteenth-century mock-heroic convention, but his use of the grotesque mode makes him the heir of Miguel de Cervantes or Francisco Quevedo. Byron’s literary identifi cation with the poetic style of the seventeenth-century baroque can be detected in his predilection for a comical deformation of characters, images and meanings. The poet uses the language of monstrosity and transgression to achieve political and religious provocation and to lure his reader into the world of a liberated language, freed from conventional connotations.
Humour Translation Studies as a New Research Discipline: Approaches to Translating Humorous Texts
Authors: Giczela-Pastwa Justyna , Gorszczyńska Paula
Published: January 2020

The paper offers an overview of the approaches to translating humour, with the intention of comparing the scope of interests and the selection of methods in a number of research reports (in English and in Polish). The overview focuses on the proposals concerning the translation of verbally expressed humour. The authors attempt to describe the status of humour translation studies as an emerging trend in Polish translation studies.
On various kinds of involvement of Avant-Garde
Authors: Szaruga (Wirpsza) Leszek (Aleksander)
Published: January 2020

The article analyses selected poems and tractates of poetry, with a special focus on the solutions regarding versifi cation, rhythm, and language (dialectological structures, syntactical forms and neologisms characteristic of poetic writing in Polish and Russian, as well as the contexts of English and German languages). Because the author attempts to distinguish the specifi city of poetry and the most important areas of literary biography in selected areas, he asks what the ways of poetry are, trying to present his point of view about the intellectual climate of the end of the 19th century, when the refl ection of language was the strongest and fundamental sign to identity. Besides, he shows what happened in the poetry of Marinetti, Majakowski, Benn, Brecht, Becher, Pound, Jasieński, Brzechwa, and Czyżewski. The article deals with the problem of historical, sociological, political, cultural and religious dialogue in poetry. The dialogue is dedicated to the search of a new language of expression. The author presents what the status of the poetry is at the beginning of the 20th century and what are the ways of poetry spreading and using language as a medium not only of communication, but also an identifi cation of unbelievable, impossibility, and as a consequence what are the strategies in poetry in addition to language (Russian and Polish, but also English and German). All of these paradigms determined functions of lyrics, which can be named an intertextual creativity. The author tries to answer the fundamental question about human condition and identity, the meaning of poetic sign, individual human possibilities towards history and politics, as well as the ways of using different connections with literature, art, religion (especially mysticism), philosophy and intertextual components which described the worldview of poetry.
Zoroastriannism in Comics
Authors: Niechciał Paulina
Published: January 2020

The article focuses on the representations of Zoroastrianism––an ancient religion
originating from Iran that has survived until the present day—in comics. The religion
is rarely represented in popular culture, including comics, and the article will reflect
on two of the most important examples: Zarathushtra (1974) and Silent Was
Zarathustra (2014). The article provides an analysis of the texts and their message
and explores how Zoroastriansim is represented in the chosen comics from a
comparative perspective, reflecting on the social context of respectively Indian and
French production that shaped the two publications, as well as their reception.
Phantasmatic instincts. Sexuality of "perverts" in Robert Crumb comics
Authors: Szałek Filip
Published: January 2020

The comic adaptation of Richard Krafft-Ebing's Psychopathia sexualis adds nothing to the
original, but the change of medium to comic from text to text-enriched series of images
distributes accents differently. Equal frames, like the pedantic gallery on the cover, build
contrast, the second element of which is the chaos prevailing in the lives of ôpervertsö whose
fate is drawn by Robert Crumb. Their deeds can entertain or shock in the short run, but the
impression that steadily builds up, and thus takes root deeper in the reader, is depression. The
medicine turns out to be a character also derived from fantasy, the queen of the jungle,
Sheena.
Sheena, the heroine of the television series, is not only the imagined companion of young
Robert Crumb, but also his phantasm, she combines the role of a sex project with the role of
an erotic tutor instructing him in the subject of fantasizing (somewhat like Mrs. de Warens,
Rousseau's „mummy” ). Sheena's way of life, her parameters as a fantasy center, sets out
paths along which the boy's erotic imagination will take place. In later episodes of the
autobiographical comic cycle My Troubles with Women, Crumb will describe his fellow

women as Sheena's shadows, fetishizing not only the physical conditions of their partners, but
also their openness.
DNS for Turbulent Premixed Combustion
Authors: Patel Dipal , Agelin-Chaab Martin
Published: January 2020

Most of practical combustion occurs in turbulent flows which involve strong coupling between turbulence and chemical processes. The heat release from combustion alters the fluid properties such as density and viscosity and in turns affects the turbulence. Direct numerical simulations (DNS) provides a tool for obtaining both temporally and spatially resolved data in three dimension (3D). This chapter presents a brief overview of importance of DNS in turbulent combustion, the role of turbulence and identifies different combustion modes. The mathematical formulation and numerical implementation for DNS are introduced. The second half of this chapter presents DNS results for ignition in both homogeneous and stratified mixtures. It has been found that minimum ignition energy is required to obtain successful ignition in different turbulence regimes. An increase in turbulent velocity fluctuation may leads to a misfire. Additionally the difference between growing flames and those which are quenched by turbulence have been discussed with the help of the reaction–diffusion balance analysis. Furthermore, the turbulence intensity and length scale of the mixture inhomogeneity have important influences on achieving self-sustained combustion following successful ignition events.
Influence of Input Parameters on the Solution of Inverse Heat Conduction Problem
Authors: C. Mehta Rakhab
Published: January 2020

A one-dimensional transient heat conduction equation is solved using analytical and numerical methods. An iterative technique is employed which estimates unknown boundary conditions from the measured temperature time history. The focus of the present chapter is to investigate effects of input parameters such as time delay, thermocouple cavity, error in the location of thermocouple position and time- and temperature-dependent thermophysical properties. Inverse heat conduction problem IHCP is solved with and without material conduction. A two-time level implicit finite difference numerical method is used to solve nonlinear heat conduction problem. Effects of uniform, nonuniform and deforming computational grids on the estimated convective heat transfer are investigated in a nozzle of solid rocket motor. A unified heat transfer analysis is presented to obtain wall heat flux and convective heat transfer coefficient in a rocket nozzle. A two-node exact solution technique is applied to estimate aerodynamic heating in a free flight of a sounding rocket. The stability of the solution of the inverse heat conduction problem is sensitive to the spatial and temporal discretization.
Politics, Ideology and Print Media: A CDA of Newspapers’ Headlines
Authors: Sajid Muhammad Akbar , Anwar Behzad , Ashraf Muhammad
Published: January 2020

The present study critically decodes the headlines of Pakistani-English newspapers to locate linguistic spin employing different political ideologies in the desired manner by the controlling groups. The headlines which appeared in the daily ‘Dawn’ and ‘Nation’
newspapers during the year 2014 have been categorised into various themes such as theme of politics, nationalism, internationalism, terrorism, and economics but in the present study, the researchers have only focused on the headlines carrying the topic of politics. In this regard, two headlines from each newspaper about the theme of politics have been randomly selected and analysed by employing Dijk’s (2006) analytical framework of critical discourse analysis (CDA). Additionally, the existing model of Dijk has been amended in accordance with the nature of the existing data. Therefore, four headlines from each newspaper randomly selected carrying political themes have been analysed to explore how different discursive techniques employed in the coinage of newspaper headlines (mis)represent the same political event differently. The researchers have investigated the print media coverage of the same event in both the newspapers’ headlines to lay bare how different discursive techniques are employed to represent the same news item by different ideological groups to propagate desired political ideologies. The findings of the study highlight that different discursive moves are used by print media to represent the same event differently to propagate desired ideology. That is how print media discourses represent certain people belonging to in/out-groups.
Subversion - The Secret Power of the Message Enlaced with the Power of the Internet and Information Technology
Authors: Bajrami Demush , Iseni Arburim , Topko Anesa
Published: January 2020

Subversion! Is it the symbol of invisibility, or the symbol of the secret power? What does it represent, the ability to carry the messages secretly, or the power to change the world? What are the ideas or objects that subversion challenges? The authority, people, tradition, institution, or the whole of humanity. Can it be considered as a way to brainwash or as a means to manipulate the thoughts and opinions of people? Is the power used by people to hide their feelings from others, be subversive? Is it the point where the change and progress meet? There are a lot of numerous and different questions that can be born from just a simple word subversion. At first glance, we think it is something simple, but its true meaning has power and many methods of expression. The whole idea and aim of subversion are to overthrow the existing state or situation and bring a functioning or desired change. It also supports the idea of staying behind and moving by one's own beliefs and choices. One of the common ways that we are exposed to subversive messages is through advertisements for different products, and the messages they carry on. Because of them, our subconscious mind is made to believe and desire things that we do not truly need or want. In the age of information technology and social media, subversive messages are carried much easier and shaped based on the characteristics of target audiences. Nowadays, advertisement and political campaigns directly respond to the individual requirements of target audiences, making their messages much more acceptable and influential.
Estudo das patologias da ponte sobre o Rio Tocantins em Porto Nacional/TO
Authors: Silva Taluane Gomes da , Santos Douglas Freitas Augusto dos
Published: January 2020

As pontes são destinadas para transpor um obstáculo natural como córrego, vale, rios e etc. Estão sujeitas a ações que provocam o aparecimento de deformações nas estruturas e assim, é preciso manutenção para manter o estado atual da obra. Ademais, a ausência de manutenção reduz a vida útil das Obras de Arte Especiais (OAE’s) e na maioria dos casos acontece o abandono da estrutura. Nesse contexto, este trabalho tem como objetivo detectar as anomalias na Ponte sobre o rio Tocantins de Porto Nacional, situada na TO – 255 através de inspeção visual e registros fotográficos com o uso de VANT (Veículo Aéreo Não Tripulado). As inspeções seguiram as diretrizes da NBR 9452 (2016) e o manual de inspeção de Pontes Rodoviárias (DNIT, 2004). Por fim, verificou-se que a ponte, segundo o critério de classificação de condição de obras de artes especiais da NBR 9452 (2016), apresenta uma condição crítica, o que torna necessário uma imediata intervenção.

Published: January 2020

O presente trabalho tem como busca desenvolver tecnicamente analises mais próximas do real tendo como principal enfoque o método refinado de análise de aproveitamento energético por meio de painéis fotovoltaicos para bombeamento de água, analisando  a eficiência dos projetos estudados bem como a sua viabilidade econômica mostrada através de um payback para obtenção de resposta de qual sistema melhor atende as necessidades de uma determinada população. Para completo entendimento do desenvolvimento a ser dado ao tema se faz necessário estabelecer e definir dois grupos de fonte de energia: as renováveis e as não renováveis, exemplificando cada uma delas. Vale ressaltar que a vantagem do uso de energia a partir de fontes renováveis não se restringe apenas ao âmbito econômico e político, focaliza também com a mesma relevância, a preservação da natureza em oposição ao impacto ambiental causado pelos combustíveis fósseis e ao consumo da água potável pela população. O método de análise é uma pesquisa exploratória, uma vez que utiliza conhecimento de um estudo de caso para resolução de problemas. Foi analisado um sistema fotovoltaico para bombeamento de água: Sistema de Bombeamento Fotovoltaico aplicado em pequenas comunidades. Partindo da viabilidade econômica o sistema provou ser econômico e com retorno financeiro rápido, além da fácil utilização e instalação do sistema. O presente estudo teve como uma de suas finalidades conscientizar e propagar a importância da disponibilidade de um recurso hídrico que é necessidade básica do ser humano, colocando em evidência dados que comprovam a crise hídrica em locais de difícil acesso à energia elétrica e ao próprio recurso natural mais precioso: Água.
Uma análise quali-quantitativa das barragens do estado do Pará com dados do Sistema Nacional de Informações Sobre Segurança de Barragens (SNISB)
Authors: Campos Maria Ilze da Silva
Published: January 2020

A preocupação com a segurança das barragens é crescente devido à importância social e os possíveis riscos ambientais serem em ampla escala, visivelmente constatados nos episódios de Mariana e Brumadinho. O Sistema Nacional de Informações sobre Segurança de Barragens registra 215 localizadas no estado do Pará, as quais serão objeto do estudo. O objetivo do trabalho é gerar uma análise quali-quantitativa focada na fiscalização e segurança das barragens no estado, considerando as classificações por Dano Potencial Associado (D.P.A.) e por Categoria de Risco (C.R.). Os dados da pesquisa foram coletados na plataforma digital do SNISB, analisados segundo a Política Nacional de Segurança de Barragens, considerando as barragens paraenses não classificadas por D.P.A. e C.R. Obteve-se como resultado que 71,63% das barragens não estão classificadas quanto D.P.A. e 72,88% não tem classificação quanto ao C.R. As entidades fiscalizadoras das barragens citadas são a SEMAS/PA e o DNPM. Foram destacadas quatro barragens, em diferentes municípios, por seus volumes e pelo material tóxico e poluente que elas armazenam. Nesse sentido a ausência da classificação compromete o monitoramento e a segurança das barragens, pois por meio dessas informações é possível identificar a intensidade dos prováveis riscos para prevenir acidentes catastrófico.
Análise das propriedades mecânicas de argamassa com adição de fibras vegetais amazônicas
Authors: Silva Kyria Maria Alves da , Ferreira Lygia Maria Policarpio
Published: January 2020

A inovação aliada com sustentabilidade é a principal proposta da produção de concretos de baixa densidade com fibras vegetais. O presente trabalho utiliza fibras vegetais amazônicas – açaí e coco, e a adição de escória de alto forno, para a produção de concreto de baixo custo com propriedades aceitáveis. Concretos com a adição de 2% de fibras vegetais sem tratamento químico, com e sem adição de escória de alto forno, foram fabricados e avaliados mecanicamente e fisicamente, em diferentes idades de cura. Os agregados naturais foram caracterizados quanto a sua granulometria e microscopia de eletrônica de varredura (MEV). Em relação ao concreto obtido, avaliou-se a influência da escória na proteção dos agregados fibrosos na zona de interface matriz-agregado, tal como a manutenção de suas especificações estruturais. Para análise do comportamento mecânico, a etapa experimental envolveu ensaios de compressão axial, porosidade e ultrassom do concreto endurecido, que apresentaram resultados satisfatórios. Além das propriedades mecânicas, a avaliação das propriedades físicas, químicas e microestruturais demonstrou que a presença de plastificantes é necessária para reduzir a porosidade, otimizando propriedades específicas dos dois componentes – concreto e resíduos fibrosos. Os resultados obtidos atendem as normas vigentes, indicando a possibilidade de incorporação ao mercado do referido concreto.

Published: January 2020

Devido ao grande volume de resíduos poliméricos, constituiu-se uma ampla problemática na destinação e tratamento adequado dos mesmos. Neste contexto, o objetivo do presente trabalho é analisar a influência da aplicação de resíduos de polipropileno (PP) triturados, provenientes da Cooperativa de Resíduos Sólidos de Tucuruí-PA, nas propriedades da argamassa em seu estado fresco. Para o desenvolvimento da pesquisa, realizou-se a coleta e o beneficiamento do resíduo, os dados obtidos foram analisados através do estudo das propriedades da argamassa em seu estado fresco, determinando sua densidade, consistência e teor de ar incorporado. Com base nos ensaios realizados, observou-se que as misturas apresentaram resultado satisfatório em relação à densidade e teor de ar incorporado para argamassas com PP quando comparadas as argamassas convencionais, entretanto houve perda da consistência. Tendo em vista que a utilização de resíduos poliméricos, embora pouco difundido, percebe-se a importância de estudos com o objetivo de analisar a viabilidade técnica de materiais alternativos enfatizando o conceito de sustentabilidade.
Treatment of Isolated Sternal Fracture with Ultrasound-Guided Paravertebral Nerve Block: a Case Report and Literature Review
Authors: Park Jun-Mo , Kim Hyunjeong
Published: January 2020

In the case of isolated sternal fractures, conservative treatment with analgesics is common, but pain can persist for more than 10 weeks, which can significantly interfere with daily life. Ultrasound-guided paravertebral nerve block is reported to be a successful means of pain control in patients with chest wall injury or rib fracture.A 70-year-old female patient presented with anterior chest pain that had persisted for 2 weeks despite conservative treatment. Sagittal reconstruction chest computed tomography and sternum lateral oblique x-ray revealed an isolated sternal fracture. An ultrasound-guided bilateral paravertebral nerve block was performed for pain control. After performing the procedure twice at a 1-week interval, the patient reported complete pain alleviation, and no other problems were observed over the 3-month follow-up period.Ultrasound-guided bilateral paravertebral nerve block can help patients with isolated sternal fractures to manage pain and return to normal activities sooner than with oral analgesics.
Structural Changes in Agriculture: Implications for the Economy of the Republic of Serbia
Authors: Stanojević Jelena , Krstić Bojan
Published: January 2020

Agriculture of the Republic of Serbia plays an important role in the national economy, making it significantly different from agriculture of developed countries. Its contribution to the national economy is reflected in a still significant share in the gross domestic product, total employment, and trade balance. Despite the insufficient utilization level of available natural resources, agriculture in Serbia is a backbone of the economic development of rural areas. The research goal of the paper is to examine structural changes in Serbian agriculture in the following aspects: changes in the employment structure, plant and animal production, as well as a change in the share of agriculture in the gross domestic product and trade balance of Serbia. The analysis has been carried out in the period from 2002 to 2017 based on the data of the Statistical Office of the Republic of Serbia. Research results show that the Serbian agriculture has suffered significant changes in the analysed areas, resulting in its decreasing share in the overall employment and gross domestic product, but also in the slight increase of its share in the value of exports and imports.
Mechanisms underlying the response of mouse cortical networks to optogenetic manipulation
Authors: Mahrach Alexandre , Chen Guang , Li Nuo , van Vreeswijk Carl , Hansel David
Published: January 2020

GABAergic interneurons can be subdivided into three subclasses: parvalbumin positive (PV), somatostatin positive (SOM) and serotonin positive neurons. With principal cells (PCs) they form complex networks. We examine PCs and PV responses in mouse anterior lateral motor cortex (ALM) and barrel cortex (S1) upon PV photostimulation in vivo. In ALM layer five and S1, the PV response is paradoxical: photoexcitation reduces their activity. This is not the case in ALM layer 2/3. We combine analytical calculations and numerical simulations to investigate how these results constrain the architecture. Two-population models cannot explain the results. Four-population networks with V1-like architecture account for the data in ALM layer 2/3 and layer 5. Our data in S1 can be explained if SOM neurons receive inputs only from PCs and PV neurons. In both four-population models, the paradoxical effect implies not too strong recurrent excitation. It is not evidence for stabilization by inhibition.
How A Hashtag Matters – Crafting Response(-Abilities) through Research-Activism on Sexual Harassment in Pre-Teen Peer Cultures
Authors: Pihkala Suvi , Huuki Tuija
Published: January 2020

This paper examines what research with children can do and become when it intra-acts with a MeToo hashtag, creative methods, experiences of sexual harassment and the making and travelling of Valentine’s Day cards. The paper is grounded within a creative research-activist project, #MeToo Postscriptum, which aimed to address sexual harassment in pre-teen peer cultures. Analyzing the project, the paper explores how the idea of response-ability manifested in three space-times of the project, and how the material-discursive practices of the project reiteratively reconfigured the conditions of possibilities to respond, react, and act against abusive gendered and sexual child peer cultures. Mapping response-ability through our research endeavours helps theorize the contingent, complex, and entangled ways research-activist methodologies can activate change, enables us to envision response-able practices to counter sexual harassment in young peer cultures, and sensitizes us as scholars and educators to our responsibilities and accountabilities that become recrafted in response.

In this paper, we explore our experiences working as team comprised of researchers, teacher, and founder and director of a sex education non-profit organisation, who have formed an intra-activist research and pedagogical assemblage to experiment with relationship and sexuality education (RSE) practices in England’s secondary schools. We draw upon phEmaterialism theory and socially engaged, participatory arts-based research methodologies and pedagogies to explore two examples of arts-based activities that have been developed to de-center humanist, male-dominated, phallocentric, penile-oriented RSE. We also demonstrate how these practices enable educators, researchers, practitioners and students to revalue and rematter feminine genitalia, and resist and refigure unsettling experiences of receiving unsolicited digital dick pics.

Background

AP2/ERF transcription factors are involved in the regulation of plant growth, development, and stress responses. Our research objective was to characterize novel apple (Malus × domestica Borkh.) genes encoding AP2/ERF transcription factors involved in regulation of plant growth, development, and stress response. The transcriptional level of apple AP2/ERF genes in different tissues and under various biotic and abiotic stress was determined to provide valuable insights into the function of AP2/ERF transcription factors in apple.

Methods

Thirty full-length cDNA sequences of apple AP2/ERF genes were isolated from ‘Zihong Fuji’ apple (Malus × domestica cv. Zihong Fuji) via homologous comparison and RT-PCR confirmation, and the obtained cDNA sequences and the deduced amino acid sequences were analyzed with bioinformatics methods. Expression levels of apple AP2/ERF genes were detected in 16 different tissues using a known array. Expression patterns of apple AP2/ERF genes were detected in response to Alternaria alternata apple pathotype (AAAP) infection using RNA-seq with existing data, and the expression of apple AP2/ERF genes was analyzed under NaCl and mannitol treatments using qRT-PCR.

Results

The sequencing results produced 30 cDNAs (designated as MdERF3-8, MdERF11, MdERF16-19, MdERF22-28, MdERF31-35, MdERF39, MdAP2D60, MdAP2D62-65, and MdRAV2). Phylogenetic analysis revealed that MdERF11/16, MdERF33/35, MdERF34/39, and MdERF18/23 belonged to groups A-2, A-4, A-5, and A-6 of the DREB subfamily, respectively; MdERF31, MdERF19, MdERF4/25/28/32, MdERF24, MdERF5/6/27, and MdERF3/7/8/17/22/26 belonged to groups B-1, B-2, B-3, B-4, B-5, and B-6 of the ERF subfamily, respectively; MdAP2D60 and MdAP2D62/63/64/65 belonged to the AP2 subfamily; and MdRAV2 belonged to the RAV subfamily. Array results indicated that 30 apple AP2/ERF genes were expressed in all examined tissues to different degrees. RNA-seq results using previously reported data showed that many members of the apple ERF and DREB subfamilies were induced by Alternaria alternate apple pathotype (AAAP) infection. Under salt treatment, many members in the apple ERF and DREB subfamilies were transcriptionally up or down-regulated. Under mannitol treatment, many members of the apple ERF, DREB, and AP2 subfamilies were induced at the transcriptional level. Taken together, the results indicated that the cloned apple AP2/ERF genes were expressed in all examined tissues. These genes were up-regulated or down-regulated in response to AAAP infection and to salt or mannitol treatment, which suggested they may be involved in regulating growth, development, and stress response in apple.

Aims: To employ valorized waste materials from Tilapia ruweti scales for removal of heavy metals from areas with major boating activities and high numbers of jetties at the Okavango delta, Botswana.

Study Design: Biowaste materials were Identified, valorized and then optimized for adsorption and removal of boating and jetty pollutants from profiled Okavango Delta surface water samples.

Place and Duration of Study: Okavango Delta, Maun and Botswana International University of Science and Technology, Palapye, Botswana between March 2017 and September 2018.

Methodology: Tilapia ruweti scales were collected from Sehithwa, Maun while water samples were collected from areas with jetties and major boating activities at Shakawe, Mboma Island and Xakanaxa. The concentration of Zn, Cu, Ni, Co, Pb and Cd at all the sampling sites were accurately determined using micro-plasma atomic emission spectroscopy (MPAES). The fish scales were pulverized and valorized by subjecting them to 12.7% vinegar. Minitab 14 software was used as a modeling tool to provide multivariate optimized parameters that affect sorption studies that included initial ion concentration, sorbent dose, contact time and solution pH. The valorized waste materials were then utilized for removal of the selected heavy metals.

Results: The optimized adsorption parameters that included contact time, solution pH, sorbent dose and initial ion concentration were ≤ 88.63 min, ≤ 8.75, ≤ 84.29 mg and ≤ 28.44 mg/L respectively. The valorized Tilapia ruweti waste displayed high removal efficiencies toward removing the selected ions from the Okavango Delta surface water samples up to 94.21% with %RSD < 2 for n = 3 (triplicate).

Conclusion: The valorized Tilapia ruweti scales were recommended as a cheap, simple and an effective method for remediation of boating pollution at the Okavango delta and other recreational areas.

The most appropriate plant density and planting pattern to use for optimum growth and yield of groundnuts (Arachis hypogaea L.) in Eswatini among those currently used is not known, as the patterns are highly influenced by environmental conditions in specific regions. A field trial was conducted with the objective of determining the optimum plant density and planting pattern for groundnut in the Wet Middleveld of Eswatini. The experiment was conducted at the University of Eswatini, Luyengo Campus during the 2018/2019 cropping. The treatments consisted of three planting densities (i.e. 88,889 plants/ha, 44,444 plants/ha, and 29,630 plants/ha) and two planting patterns (i.e. Ridges and Raisedbeds) in a split plot arrangement. Results showed that all the measured parameters including seed yield were not significantly different in all treatments. However, the highest seed yield was obtained at low plant density which was 71.4 kg/ha followed by 568 kg/ha at medium and the least was 434 kg/ha at high plant density. The high plant density (88889 plants/ha) obtained the highest value of dry biomass (13018 kg/ha) at ridges which was higher than 3859 kg/ha obtained at the low plant density (29630 plants/ha) at raised beds at R6 growth stage. The ridges at the intermediate plant density (44444 plants per hectare) obtained the highest shelling percentage of 59.67% while the lowest (56%) shelling percentage was obtained at raised beds at 88889 plants per hectare. It is concluded that groundnuts at raised beds with low plant density yielded higher than those at ridges with high plant density. It is therefore, recommended that groundnuts be planted at raised beds with low plant density to increase groundnut production and for ease of harvesting.

Introduction: Tuberculosis (TB) is a chronic infectious disease caused by bacterium “Mycobacterium tuberculosis”. It is a systemic infection and has deleterious effect on both circulatory and respiratory systems, and thrives more in a society with little knowledge of its predisposing factors.

Aim of the Study: This study was carried out to identify the predisposing factors of tuberculosis and its effects on haematological indices of the positive patients at the Federal Medical Center, Owerri, Imo state, Nigeria.

Materials and Methods: The blood samples were analyzed manually for the indices while predisposing factors of Tuberculosis were obtained with the aid of a structured self-administered questionnair,these were administered simultaneously while the blood samples were been collected.

Results and Discussion: Results were considered to be statistically signifificant (P<0.05), (OR>1). Simple frequencies were also computed. The results revealed that Haemoglobin (P=0.001); Erythrocyte sedimentation rate (P=0.020); Neutrophils (P=0.002); Eosinophils (P=0.000); Monocytes (P=0.000); Platelets (P=0.001) of the Tuberculosis positive patients when compared with the controls, showed, statistically (P<0.05) significant haematological abnormalities. History of Tuberculosis in family (Odd ratio=9.3) and Alcoholism (OR=6.0) were significant predisposing factors of Tuberculosis. Other predisposing factors; smoking habits (OR=2.7), Educational status (OR=2.2), marital status (OR=1.3) were also associated with Tuberculosis infection, while employment status (OR=1.0) and socio-economic status (OR=0.1) were not. Tuberculosis infection in this study adversely affected Haemoglobin, Platelets, Erythrocyte sedimentation rate, Neutrophil, Eosinophil and Monocyte values, while family history of Tuberculosis and Alcoholism were significantly associated with the infection.

Conclusion: Quarrantine of Tuberculosis patients and creating more awareness on the predisposing factors of tuberculosis will help towards preventing, reducing and eliminating the disease.
