Winds in Star Clusters Drive Kolmogorov Turbulence
Authors: Gallegos-Garcia Monica , Burkhart Blakesley , Rosen Anna L. , Naiman Jill P. , Ramirez-Ruiz Enrico
Published: August 2020

Intermediate and massive stars drive fast and powerful isotropic winds that interact with the winds of nearby stars in star clusters and the surrounding interstellar medium (ISM). Wind–ISM collisions generate astrospheres around these stars that contain hot T ∼ 107 K gas that adiabatically expands. As individual bubbles expand and collide they become unstable, potentially driving turbulence in star clusters. In this Letter we use hydrodynamic simulations to model a densely populated young star cluster within a homogeneous cloud to study stellar wind collisions with the surrounding ISM. We model a mass-segregated cluster of 20 B-type young main-sequence stars with masses ranging from 3 to 17 M
⊙. We evolve the winds for ∼11 kyr and show that wind–ISM collisions and overlapping wind-blown bubbles around B-stars mix the hot gas and ISM material, generating Kolmogorov-like turbulence on small scales early in its evolution. We discuss how turbulence driven by stellar winds may impact the subsequent generation of star formation in the cluster.
Color Gradients along the Quiescent Galaxy Sequence: Clues to Quenching and Structural Growth
Authors: Suess Katherine A. , Kriek Mariska , Price Sedona H. , Barro Guillermo
Published: August 2020

This Letter examines how the sizes, structures, and color gradients of galaxies change along the quiescent sequence. Our sample consists of ∼400 quiescent galaxies at 1.0 ≤ z ≤ 2.5 and

in three CANDELS fields. We exploit deep multi-band Hubble Space Telescope imaging to derive accurate mass profiles and color gradients, then use an empirical calibration from rest-frame UVJ colors to estimate galaxy ages. We find that—contrary to previous results—the youngest quiescent galaxies are not significantly smaller than older quiescent galaxies at fixed stellar mass. These “post-starburst” galaxies only appear smaller in half-light radii because they have systematically flatter color gradients. The strength of color gradients in quiescent galaxies is a clear function of age, with older galaxies exhibiting stronger negative color gradients (i.e., redder centers). Furthermore, we find that the central mass surface density Σ1 is independent of age at fixed stellar mass, and only weakly depends on redshift. This finding implies that the central mass profiles of quiescent galaxies do not significantly change with age; however, we find that older quiescent galaxies have additional mass at large radii. Our results support the idea that building a massive core is a necessary requirement for quenching beyond z = 1, and indicate that post-starburst galaxies are the result of a rapid quenching process that requires structural change. Furthermore, our observed color gradient and mass profile evolution supports a scenario where quiescent galaxies grow inside-out via minor mergers.

Space-weathering as well as shock effects can darken meteorite and asteroid reflectance spectra. We present a detailed comparative study on shock-darkening and space-weathering using different lithologies of the Chelyabinsk LL5 chondrite. Compared to space-weathering, the shock processes do not cause significant spectral slope changes and are more efficient in attenuating the orthopyroxene 2 μm absorption band. This results in a distinct shock vector in the reflectance spectra principal component analysis, moving the shocked silicate-rich Chelyabinsk spectra from the S-complex space into the C/X complex. In contrast to this, the space-weathering vector stays within the S complex, moving from Q type to S type. Moreover, the 2 μm to 1 μm band depth ratio (BDR) as well as the 2 μm to 1 μm band area ratio (BAR) are not appreciably affected by shock-darkening or shock melting. Space-weathering, however, causes significant shifts in both BDR and BAR toward higher values. Application of the BDR method to the three distinct areas on the asteroid Itokawa reveals that Itokawa is rather uniformly space-weathered and not influenced by regolith roughness or relative albedo changes.
A Volatile-poor Formation of LHS 3844b Based on Its Lack of Significant Atmosphere
Authors: Kane Stephen R. , Roettenbacher Rachael M. , Unterborn Cayman T. , Foley Bradford J. , Hill Michelle L.
Published: August 2020

Exoplanet discoveries have reached into the realm of terrestrial planets that are becoming the subject of atmospheric studies. One such discovery is LHS 3844b, a 1.3 Earth radius planet in a 0.46 day orbit around an M4.5-5 dwarf star. Follow-up observations indicate that the planet is largely devoid of substantial atmosphere. This lack of significant atmosphere places astrophysical and geophysical constraints on LHS 3844b, primarily the degree of volatile outgassing and the rate of atmosphere erosion. We estimate the age of the host star as 7.8 ± 1.6 Gyr and find evidence of an active past comparable to that of Proxima Centauri. We use geodynamical models of volcanic outgassing and atmospheric erosion to show that the apparent lack of atmosphere is consistent with a volatile-poor mantle for LHS 3844b. We show the core is unlikely to host enough C to produce a sufficiently volatile-poor mantle, unless the bulk planet is volatile-poor relative to Earth. While we cannot rule out a giant impact stripping LHS 3844b’s atmosphere, we show that this mechanism would require significant mantle stripping, potentially leaving LHS 3844b as an Fe-rich “super-Mercury.” Atmospheric erosion by smaller impacts is possible, but only if the planet has already begun degassing and is bombarded by 103 impactors of radius 500–1000 km traveling at escape velocity. We discuss formation and migration scenarios that could account for a volatile-poor origin, including the potential for an unobserved massive companion planet. A relatively volatile-poor composition of LHS 3844b suggests that the planet formed interior to the system snow line.

Published: August 2020

Geum sunhangii– first discovered in Shennongjia National Nature Reserve, Hubei Province, China – is described as a new species of Rosaceae. Compared to all known ChineseGeumspecies, the new species differs by possessing jointed styles, imbricate petals and a reniform radical leaf terminal leaflet. Most significantly, the jointed style is curved at an obtuse or a right angle. In addition, the inclusion of this species within the genusGeumwas supported by phylogenetic analysis using the sequence data of a nuclear ribosomal internal transcribed spacer (nrITS) and a chloroplasttrnL–trnFintergenic spacer. The new species was found to be closely related toG. rivaleandG. aleppicum.
Comparative wood anatomy of Korean Viburnum L. (Adoxaceae) and its taxonomic implication
Authors: Ghimire Balkrishna , Son Dong Chan , Park Beom Kyun , Oh Seung-Hwan
Published: August 2020

Comparative wood anatomy of Viburnum was carried out to understand the differences in wood features amongst the species which might be useful for taxonomic discrimination in the genus. Altogether, nine taxa belonging to five clades were investigated using a sliding microtome and light microscopy. The growth rings are well represented and earlywood and latewood are distinguishable in cross-section. Some of the important wood features include angular, oval and rounded vessels with scalariform perforation plates, opposite to scalariform inter-vessel pitting, rounded pits with slit-like apertures, thick-walled xylem tracheids with simple, rounded bordered pits, diffuse axial parenchyma, uni- and multiseriate rays, 2–4 cells wide. In general, there is a remarkable uniformity in the qualitative wood features in Viburnum species, although quantitative measurement showed some disparities. The most significant quantitative wood variables which might be useful for taxonomic groupings of the species comprise a frequency of vessels and rays, the diameter of the vessels and tracheids in the radial and tangential planes and height and width of rays in the tangential plane.
Une norme disputée : l’indemnité parlementaire en France (1789-1914)
Authors: Monier Frédéric , Portalez Christophe
Published: August 2020

La création d’une indemnité législative intervient en France à l’été 1789. Imbriquée dans les projets révolutionnaires, elle suscite la gêne de nombreux députés, et attise des débats récurrents. Remise en cause par le premier Empire, abrogée par la monarchie censitaire, réintroduite en 1848, cette norme nouvelle est paradoxalement confortée par le Second Empire. Le traitement des élus ne va pas de soi, y compris après 1870 : les refus persistants de dédommager les mandats locaux et l’indignation suscitée par l’augmentation de l’indemnité parlementaire fin 1906 montrent que, pour une partie de la société française, l’idée que la politique soit un métier rémunéré est perçue comme une corruption, encore à la veille de la Grande Guerre.
Éduquer pour la République, Jeanne Desparmet-Ruello, une intellectuelle au temps de Jaurès
Authors: Fabre Mélanie
Published: August 2020

Méconnue de l’historiographie, Jeanne Desparmet-Ruello est une intellectuelle qui, dans le sillage de Jaurès, considère l’école laïque comme une priorité pour la Troisième République. Dreyfusarde, elle est la fondatrice et présidente de l’Université populaire lyonnaise qu’elle fait vivre entre 1899 et 1905. Femme de science aux convictions rationalistes, elle milite pour appliquer partout la laïcité scolaire dans un contexte de concurrence avec l’école catholique. Libre penseuse, elle se prête à des manifestations qui lui attirent des attaques dans la presse lyonnaise et des conflits avec son administration. Directrice du lycée de jeunes filles de Lyon, Jeanne Desparmet-Ruello éprouve les limites de sa liberté d’action et de parole, dans un contexte où les femmes professeurs, pour faire se faire accepter socialement, doivent se conformer à un idéal de discrétion. Par ailleurs, les engagements de Jeanne Desparmet-Ruello ne sont pas toujours jugés compatibles avec son statut de fonctionnaire, qui impose devoir de réserve et de neutralité. C’est donc sous un pseudonyme qu’on la retrouve dans les colonnes de la Fronde , quotidien qui associe la lutte féministe au combat pour les droits de l’homme dans le contexte de l’Affaire. Grande actrice de l’éducation populaire, Jeanne Desparmet-Ruello se revendique socialiste, mais adopte des positions plutôt hétérodoxes. En quoi consiste donc son socialisme ? Peut-il être qualifié de jaurésien ? Pourquoi est-il indissociable de son engagement féministe, dreyfusard et libre penseur ?
L’Internationale et la grève du bronze de 1867 : une renaissance de la Première Internationale
Authors: Grimaud Julien
Published: August 2020

Fortement enraciné et unanimement professé, le credo proudhonien des sections françaises de l’Internationale à ses débuts s’accompagne, au cours de l’intervalle des années 1867-1869, d’une pratique qui en contredit cependant fondamentalement le paradigme : la grève ! Cette contradiction, que le seul prisme idéologique de l’historiographie consacrée laissa longtemps impensée, se révèle notamment à l’occasion de la grande grève des ouvriers bronziers de mars-avril 1867 à Paris. Une grève dont la démonstration de force de l’AIT (Association interna- tionale des travailleurs) et les décantations politique qu’elle occasionne sur le long terme, offrent matière à l’analyse d’une étiologie sociale de la mutation du petit cercle d’étude proudhonien en un véritable outil de résistance ouvrière.
Un portraitiste de Jaurès, Éloy-Vincent
Authors: Huard Raymond
Published: August 2020

Parmi les très nombreux auteurs de représentations de Jaurès, la place d’Albert Éloy-Vincent n’est sans doute pas la plus importante, mais elle est néanmoins assez originale pour qu’on s’intéresse de plus près à son auteur. Si son tableau qui contient six dessins de Jaurès parlant à la Chambre en 1910 intitulé «  Croquis pour servir à l’histoire de l’éloquence », conservé au Centre national et musée Jaurès de Castres, est bien connu et a été reproduit de nombreuses fois à l’appui d’un article ou d’un livre sur Jaurès, son auteur en revanche est à peu près ignoré. Qui était-il ? Comment s’est-il intéressé à Jaurès ? A-t-il donné d’autres représentations du leader socialiste ? Quelle place exacte occupe Jaurès dans ce qu’on peut appeler son panthéon républicain ? C’est à ces questions que cet article cherche à répondre.
CARACTERIZAÇÃO DAS ÁREAS VERDES NO PERÍMETRO URBANO DE MARECHAL CÂNDIDO RONDON - PR
Authors: Henke Gabriela De Bona Wild , Hornes Karin Linete
Published: August 2020

A inclusão das áreas verdes proporcionam espaços que contribuem para a melhoria de vida da população e tornam um meio de interação das atividades humanas com o meio ambiente. As praças e parques são elementos dentro do espaço urbano, que quando bem estruturados servem a população e auxiliam no combate a degradação, além de amparar na recuperação, proteção e conservação do patrimônio ambiental. Neste contexto o presente estudo tem como objetivo caracterizar as áreas verdes do perímetro urbano do município de Marechal Cândido Rondon. Para isso realizou-se uma abordagem da evolução do espaço urbano em relação às áreas verdes no período de 1960 a 2017, além de localizar, quantificar e qualificar essas áreas com o propósito de se calcular o Índice de Áreas Verdes (IAV). Para saber como o município está administrando essas áreas utilizou-se a metodologia proposta por Fontes e Shimbo (2003) que sugerem que ocorra o planejamento e monitoramento dessas áreas e que se tenha um equilíbrio entre qualidade, quantidade e distribuição. Após essa análise percebeu-se a necessidade de melhorias nas áreas verdes existentes, a utilização das áreas de proteção ambiental e inserção de novas praças e parques lineares, melhorando a qualidade ambiental e criando opções de lazer.

Social distancing and dangers of access block to health care services during COVID-19 pandemic
Authors: Saban Mor , Shachar Tal
Published: August 2020

An outbreak of the novel coronavirus (COVID-19) that started in Wuhan, China, has spread quickly, with cases confirmed in 180 countries with broad impact on all health care systems. Currently, the absence of a COVID-19 vaccine or any definitive medication has led to increased use of non-pharmaceutical interventions, aimed at reducing contact rates in the population and thereby transmission of the virus, especially social distancing. These social distancing guidelines indirectly create two isolated populations at high-risk: the chronically ill and voluntary isolated persons who had contact with a verified patient or person returning from abroad. In this concept paper we describe the potential risk of these populations leading to an 80% reduction in total Emergency Department (ED) visits, including patients with an acute condition. In conclusion, alternative medical examination solutions so far do not provide adequate response to the at-risk population. The healthcare system must develop and offer complementary solutions that will enable access to health services even during these difficult times.
Thymus vulgaris L. as a possible effective substitute for nitrates in meat products
Authors: Salvaneschi Serena , Iriti Marcello , Vitalini Sara , Vallone Lisa
Published: August 2020

Nitrates are chemicals found naturally in some foods such as fruit and vegetables or added to others, especially meats, as a preservative. Their use as additives is regulated by European Commission to avoid any risk for human health. In order to reduce or replace the use of these compounds, we investigated the bacteriostatic/bactericidal activity of the essential oil of Thymus vulgaris L. against Listeria innocua, a nonpathogenic microorganism with the same morpho-cultural traits of L. monocytogenes. The study was carried out in vitro and in vivo on processed meat products, i.e. mature salami, by using thyme essential oil. Although the results are preliminary, the antilisterial activity of the thyme essential oil was shown to be similar to that of nitrates.
Giant cell tumor formation due to metallosis after open latarjet and partial shoulder resurfacing
Authors: Wolfson Matthew , Curtin Patrick , Curry Emily J. , Cerda Sandra , Li Xinning
Published: August 2020

Shoulder metallosis with giant cell tumor formation is rarely seen in shoulder surgery. With an increase in shoulder arthroplasty and complex revision shoulder surgeries, clinicians should have an index of suspicion for possible metallosis in patients that presents with unexplained persistent pain with metal components on both the glenoid and humeral side. This case describes a 43-yearold female with a history of six prior shoulder surgeries who presented with shoulder metallosis and giant cell tumor formation after a screw from her open Latarjet procedure began rubbing against her Hemicap implant. She successfully underwent a revision total shoulder arthroplasty for post traumatic arthritis with pectoralis major transfer for her chronic subscapularis rupture and had complete symptom resolution.

Published: August 2020

O Brasil é um dos maiores plantadores de cana-de-açúcar. É de extrema importância que seja feita minuciosa análise com base na área plantada para que possa ser estimada a produtividade agrícola em questão. Nesse contexto, o presente trabalho tem como objetivo fazer uma estimativa da área plantada de cana-de-açúcar no município de Campos dos Goytacazes – RJ utilizando o Sensoriamento Remoto como ferramenta de análise. A metodologia consistiu no uso das imagens do Satélite LANDSAT-8 referentes ao ano-safra 2017/2018 processadas no software livre SPRING versão 5.5.5. As ferramentas que possibilitaram a culminância do resultado final foram: interpretações visuais para delimitação das áreas de plantio e identificação das áreas onde seja permitido efetuar a queima da palha na colheita, utilizando para isto a Linguagem Espacial para Geoprocessamento Algébrico (LEGAL) em consonância com o uso dos modelos digitais de elevação ASTER, SRTM e TOPODATA. Os resultados apontaram uma área plantada de 25.238,34 hectares no referido município, dentre as quais apresentam declividade superior a 12% entre 742,14 e 3.159,65 hectares. As conclusões apontaram para divergências entre valores levantados no presente projeto de pesquisa e os calculados pelo IBGE e CONAB para o referido ano-safra.
Praça das Nações e Parque Ecológico CIMBA em Araguaína/TO: espaços públicos na Amazônia legal

Published: August 2020

Particularizamos dois recortes espaciais na cidade de Araguaína/TO: Praça das Nações e Parque Ecológico Cimba, que serão pensados à luz da Análise de Discurso francesa, a partir das teorizações de Orlandi (1999) sobre a “ordem do discurso urbano”. Por meio da categoria “organização” produzimos um diálogo com teóricos da geografia e da arquitetura/urbanismo. Definimos aqueles recortes conceitualmente como espaços públicos e problematizamos como são produzidos. Recorremos a um portal de notícias local para enfocar condições de produção, perseguindo o seguinte questionamento: de que modo a ordem do discurso urbano operou efeitos na revitalização daqueles espaços? Percebe-se uma contradição nessa revitalização, já que a “organização” busca inscrever o quê, supostamente, atrapalha a ordem urbana na discursividade da expulsão. Sobre o primeiro espaço, revitaliza-se para ressignificar a infraestrutura precária e expulsar população em situação de rua. Sobre o segundo, revitaliza-se para ressignificar os “vazios urbanos”, impedindo o descarte irregular de lixo. Em ambos, as práticas sociais figuram como subterfúgio para o projeto de urbanização.

Published: August 2020

Introdução: O uso de meias de compressão com o objetivo de otimização do desempenho vem se popularizando de maneira significativa, porém muitas ainda são as perguntas para saber se de fato elas possuem capacidade ergogênica. Objetivo: Avaliar agudamente o uso de meias de compressão (MC) sobre o YoYo intermitente endurance teste 2 (YoYoIE2) e indicadores fisiológicos em futebolistas. Métodos: Oito futebolistas do sexo feminino realizaram de maneira cruzada e randômica o YoYoIE2 usando MC ou meias controle (CON). Resultados: A distância percorrida no YoYoIE2 não diferiu (p=0,11) entre MC (827,5 ± 350 metros) e CON (655 ± 237 metros), mas o tamanho do efeito foi moderado (0,60). O desempenho individual em 75% foi maior usando as MC do que as CON. Percepção subjetiva de recuperação, lactato em repouso e pós teste, frequência cardíaca (FC) pico, FC de recuperação e percepção subjetiva de esforço não diferiram (p>0,05) entre MC e CON. Conclusão: O uso de MC durante exercício intermitente pode ter efeito ergogênico quando considerado o tamanho do efeito moderado e as respostas individuais. Porém as MC parecem não influenciar indicadores fisiológicos e de intensidade associados ao YoYoIE2.

Published: August 2020

Em meados dos anos 2000, as atividades circenses passaram a figurar como tema de pesquisa na Educação Física brasileira, no entanto, grande parte desses estudos está centrada na região sudeste do país. Nesse contexto, o presente artigo objetiva apresentar um levantamento das produções científicas que abordam a atividade circense na região centro-oeste do Brasil. Para isso foi realizada uma revisão sistemática em duas bases de dados, utilizando descritores em português. Como critério de inclusão, instituiu-se artigos publicados no período de 2015 a 2020, em periódicos publicados em língua portuguesa. Foram encontrados 12 artigos de relevância para essa pesquisa, separados em 5 categorias; 1) circo como ferramenta pedagógica; 2) contribuições para o desenvolvimento da criatividade e expressão corporal; 3) formação continuada de professores; 4) formação do artista circense; 5) circo como manifestação capitalista. Mesmo sendo encontradas poucas produções em relação à região delimitada, pode-se notar que já começa a haver um aumento gradativo nas produções com essa temática. Com isso, existe um avanço no que diz respeito à pesquisa na área circense na região centro-oeste, visto que se trata de uma área do conhecimento pouco investigada em relação a outras.

DETERMINATION OF CANINE DIROFILARIASIS BY ELISA METHOD AND MODIFIED KNOTT'S TEST
Authors: Savić Sara , Grgić Živoslav , Vujkov Biljana , Fenjac Ivan , Pajković Dušan , Žekić Marina
Published: August 2020

Canine dirofilariasis is a parasitic disease. The causative agent is Dirofilaria immitis or Dirofilaria repens. It may appear as skin or as a heart disease. The heart form of the disease is often named "heartworm" disease, because the adult parasites live in the heart. In the last five years, several cases of dirofilariasis have been reported (Dimitrijević, 1999; Savić-Jevđenić et al., 2004). At the beginning dirofilarias was discovered only as a by-the-way finding during autopsy, but last two years there were more requests for examination of dirofilariosis in alive dogs. Clinical symptoms in dogs with dirofilariosis are occasional coughing, apathy, breathing difficulties, heart failure, progressive loss of weight and rapid fatigue. The variety of symptoms depends on the intensity of infection, and the symptoms depend on the activity of a dog. For the diagnostics of dirofilariosis, the modified Knott's test or another serology methods may be used. In our research we used 45 blood samples, taken from the dogs in the region where dirofilariosis was detected mostly through autopsy, but also from the dogs with clinical symptoms in which cases the owners or veterinarians had sent the samples for analysis. The modified Knott's test was used for proving microfilaria in full blood and ELISA test was applied for detection of D. immitis antigen. Out of 35 examined dogs with no clinical symptoms, in 4 dogs the presence of antigene Dirofilaria immitis was detected in blood sera, which is 11% of the examined dogs. The examination of 10 dogs with clinical symptoms (coughing, difficult breathing, apathy and rapid fatigue) showed the presence of microfiliaria in circulation (ELISA test) and the presence of antigen D. immitis in 8 dogs. Therapy was successful in two cases.
The Sketch of Age in Shakespeare’s Henry IV (Parts 1 and 2)
Authors: Sarkar Dipak Kumar
Published: August 2020

As there is birth, everything including human being is certain of the journey of being aged but the society and its various institutions became dogmatic at the time of approaching an aged man focusing on their norms and culture. On the other hand, there is no universal definition or margin of calling a person aged. Despite the people in the society, however knowledgeable and gifted they are, keep on pursuing the social norm and cannot think over it. Shakespeare is also one of them who consider the age as the society sees. But, being an undisputed and world class writer, this approach cannot be expected from Shakespeare. And so, this paper investigates Shakespeare’s attitude towards age and aged people in comparison to the young in the both parts of the drama, Henry IV. For this investigation, the text with all its annotations and critics’ comments are analysed minutely from a gerontological point of view. This study also examines the concept of aging in some other works of Shakespeare.

Nature as a Motif in Arabic Andalusian Poetry and English Romanticism
Authors: Aburqayeq Ghassan
Published: August 2020

This paper examines some tenets in the Andalusian and Romantic poetry and shows how poets such as Ibrahim Ibn Khafāja (1058-1138) and William Wordsworth (1770 –1850) used nature as a motif in their poetry. Relying on a historical approach, this paper links smaller features such as themes and literary devices in the Andalusian and Romantic poetry with larger features, including genre, traditions, and cultural system. I argue that the emphasis on both the larger and smaller features of poetry creates what Franco Moretti calls “distant reading.” Comparing and contrasting Ibn Khafāja’s “the Mountain” and Wordsworth’s “the Daffodils,” for instance, introduces nature as a recurrent theme in both Andalusian and Romantic literary traditions, reinforcing Johann Wolfgang Goethe’s description of poetry as a common possession of humanity” (Goethe 229). In addition to that, comparing the images and themes in both the Andalusian and Romantic poetry not only shows internally linked meanings, but it creates what Cesar Domínguez, et al, call “a space for polyglottism, multidisciplinarity, scholarly collaboration” (75). Reading these works and movements closely and distantly serves as a cross-cultural dialogue between the Arabic and English poetic conventions. While Ibn Khafāja and Wordsworth lived in different places and times, wrote in different languages, and did not have the same socio-political circumstances, their poems show the richness and multiplicity of the historical experience of world literature.
Migration and Its Discontents: A Postcolonial Rendering of NoViolet Bulawayo’s We Need New Names
Authors: Babou Ngom Mamadou Abdou
Published: August 2020

This research paper is my attempt, through a blow-by-blow analysis of a fictional work of a rising star in postcolonial writing, to grapple with the manifold discontents that attend the event of migration. Migration is an astoundingly painful experience to go through, whose multifaceted toll on the subject may be beyond repair. Using NoViolet Bulawayo’s We Need New names as a stepping-stone, I argue that migration, albeit a time-honoured phenomenon has picked up speed in the twentieth-century and continued into the twenty-first century with a most heavy human toll. The paper emphasizes that even though the act of migration is underpinned by a hope for betterment, it may turn out to be a damp squid. No end of landmines and hiccups dot the migratory journey. The long-suffering postcolonial subject, hallmarked by the stifling strictures of marginality owing to a long history of race-based oppression that stretches back to the gruesome eras of the trans-Atlantic slave trade and colonization, is on the receiving end of the horrors of migration. I tap into key terms in postcolonial theory cum sociology-informed perspectives to make a valid point about the dehumanizing fallout from the migratory experience.
The African Verbal Genre as Literature and Performance
Authors: Bula Andrew
Published: August 2020

There is a view that the African verbal genre is not literature and its nature does not include bodily performance; it belongs to sociology and not literature because literature is the art that is written while African verbal genre is presented orally. Thus, the present study aims to demonstrate that, despite its oral nature, the African verbal genre is both literature and oral performance that includes bodily performance and that its literary and performative constituents synergize to achieve the purpose of the genre.

Published: August 2020

One of the major areas of interest in SLA research is the study of the ways in which expert and non-expert readers respond to L2 texts and the fundamental changes that can be brought about in their L2 reading processes through formal instruction. In line with this research tradition, the present quasi-experimental study investigated the effects of formal training in figures of speech on university EFL learners’ appreciation of an unseen literary text, Martin Luther King’s “I Have a Dream” in the case of this study. Understanding literature requires knowledge of figures of speech.An experimental group (n=29) and a control group (n=26) of intermediate 3rd year EFL learners, studying English for a B.A. degree at Kashan University, Iran, participated in the study. The participants were first pre-tested and matched for their level of proficiency in English and their initial reading comprehension ability. In addition to the normal curriculum content, the experimental group received instruction in figures of speech through a course called "Fonun va Sana'at" (Figures of Speech). The control group did not receive this instruction. Both groups were post-tested on their ability to read a literary passage and to appreciate it.The results of t-test analysis of the resulting data revealed significant differences between the means of the two groups. The experimental group that had received instruction in figures of speech significantly outperformed the control group. The findings of the study have practical implications for material development, curriculum planning, teaching English through literature, and second language acquisition.
Integration of Work and Leisure in the Performance of Spoken Word Poetry in Kenya
Authors: Ekesa Beatrice Jane
Published: August 2020

Spoken word poetry, an emerging genre in Kenyan literature, is popular among the urban population. The performance of this creative work draws audience from different socio-economic backgrounds who view it as a source of entertainment. Majority of these poets begin off by staging performances in order to exercise their talents and entertain their audience without financial gain. However, once they get the desired popularity, their interests change and they begin to view the performance of spoken word poetry as an alternative source of income. It is against this background that this paper seeks to explore the relationship between work and leisure in the performance of spoken word poetry in Kenya. Scholars in the field of leisure studies are constantly seeking the relationship between work and leisure. This research seeks to examine the representation of labour and leisure in the creative industry of spoken word poetry in Kenya. The study explores the characteristics of work and leisure to determine the leisure/work relationship in the performance of spoken word poetry in Kenyan literature.

NONTRADITIONAL METHOD OF CHEMICAL MODIFICATION OF THE SURFACE OF POROUS SILICA
Authors: Kamalyan T.O.
Published: August 2020

The main results obtained in the study of the possibility of low-temperature chemical modification of porous silica, applying various nanodispersed substances to their surface are given. It has been shown that the use of the chemical transport reaction (CTR) H2O2/ZnO for this purpose with the participation of H2O2 vapors at room temperature makes it possible to apply a number of oxides, sulfides and metal halides to the surface of various sorbents. An important advantage of the proposed modification method is that changes in the original texture parameters of the substrate are minimized. Using the example of modifying the behavior of highly pure SiO2 with zinc oxide, it was shown that the decomposition of gaseous intermediate products of CTR H2O2/ZnO occurs mainly in pores with a diameter of more than 6 nm.
