One hundred and twenty, one day old Anak breeds were randomly assigned to five treatment diets. Each group was replicated into four with six birds per replicate. Five experimental diets were formulated with diet 1 (T1) as control, contained 0% Goat Blood-Rumen Content Mixture (GBRCM) and aromatic plants. Diet 2 (T2) contains 10% GBRCM without aromatic plants supplementation. Diet 3, 4 and 5 (T3, T4 and T5) contained 10% goat blood-rumen content mixture supplemented with garlic (Allium sativum), ginger (Zingiber officinale) and rosemary (Rosemarinus officinalis). The experiment lasted for 56 days. Parameters evaluated were; body weight gain, feed intake, feed conversion ratio, protein intake, protein efficiency ratio, nutrient digestibility and economics of production. The results showed that birds fed with aromatic plant supplemented had significantly (P<0.05) higher body weight gain, feed intake and superior feed conversion ratio than birds fed with unsupplemented and control. There was no significant (P>0.05) difference on the parameters of the birds fed with control diet T1 and T2 among the treatments. Diet T3 formulated with 10% goat blood-rumen content and 5 grams of Allium sativum indicated the best performance followed by diet T4 and  diet T5 . This showed that the goat blood-rumen content based-diet supplemented with  aromatic reduced the high cost of feed material, ensured greater productivity and has no adverse effect on health status of the birds. The GBRCM based-diet supplemented in the broiler bird's diets reduced the cost of production with no adverse effect on performance.

Liver diseases are a worldwide problem. Medicinal plants are being increasingly utilized to treat a wide variety of diseases, liver disorder inclusive. The effect of aqueous leaf extracts of Vernonia amygdalina on acetaminophen-induced liver damage via the assessment of the histopathological examination was examined. Five groups of albino rats were used (n = 5). Animals in group 1 were fed normal laboratory pellet and water ad libitum (Control); those in group 2 received 3000mg/kg of acetaminophen alone. Groups 3, 4 and 5 received 3000mg/kg of acetaminophen and in addition 50mg/kg Vernonia amygdalina leaf extract. 100mg/kg Vernonia amygdalina leaf extract and 200mg/kg Silymarin, respectively for 14 days. Twenty-four hours after the last administration, the animals were sacrificed. The organs (liver) was excised and used for the histopathological examination. Histological examinations of the liver showed acetaminophen-induced hepatotoxicity. Histology of the liver revealed altered cellular architecture (poor architecture, moderate to severe congestion of the portal vein as well as severe peri portal infiltration of inflammatory cells, the liver parenchyma also showed area with destroyed liver plates with severe hemorrhage and necrosis. The morphology of the hepatocytes showed some degenerated liver cells, the liver parenchyma also showed focal area of moderate aggregate of inflammatory cells) following administration of acetaminophen (Group 2). Normal histological features were restored after treatment with aqueous leaf extract of Vernonia amygdalina. The study has demonstrated that aqueous leaf extract of Vernonia amygdalina ameliorate liver of rats against acetaminophen-induced toxicity and modulates the adverse effects of acetaminophen on the liver

Published: February 2021

Abstract. There are few long-term datasets of volatile organic compounds (VOCs) in the High Arctic. Furthermore, knowledge about their source regions remains
lacking. To address this matter, we report a multiseason dataset of highly time-resolved VOC measurements in the High Arctic from April to October
2018. We have utilized a combination of measurement and modeling techniques to characterize the mixing ratios, temporal patterns, and sources of
VOCs at the Villum Research Station at Station Nord in northeastern Greenland. Atmospheric VOCs were measured using proton-transfer-reaction time-of-flight mass
spectrometry. Ten ions were selected for source apportionment with the positive matrix factorization (PMF) receptor model. A
four-factor solution to the PMF model was deemed optimal. The factors identified were biomass burning, marine cryosphere, background, and Arctic
haze. The biomass burning factor described the variation of acetonitrile and benzene and peaked during August and September. The marine cryosphere
factor was comprised of carboxylic acids (formic, acetic, and C3H6O2) as well as dimethyl sulfide (DMS). This factor displayed peak
contributions during periods of snow and sea ice melt. A potential source contribution function (PSCF) showed that the source regions for this
factor were the coasts around southeastern and northeastern Greenland. The background factor was temporally ubiquitous, with a slight decrease in
the summer. This factor was not driven by any individual chemical species. The Arctic haze factor was dominated by benzene with contributions from
oxygenated VOCs. This factor exhibited a maximum in the spring and minima during the summer and autumn. This temporal pattern and species profile
are indicative of anthropogenic sources in the midlatitudes. This study provides seasonal characteristics and sources of VOCs and can help
elucidate the processes affecting the atmospheric chemistry and biogeochemical feedback mechanisms in the High Arctic.
Analysis of 3D cloud effects in OCO-2 XCO2 retrievals
Authors: Massie Steven T. , Cronk Heather , Merrelli Aronne , O'Dell Christopher , Schmidt K. Sebastian , Chen Hong , Baker David
Published: February 2021

Abstract. The presence of 3D cloud radiative effects in OCO-2 retrievals is
demonstrated from an analysis of 2014–2019 OCO-2 XCO2 raw retrievals, bias-corrected XCO2bc data, ground-based Total Carbon Column Observation Network
(TCCON) XCO2, and Moderate Resolution Imaging Spectroradiometer (MODIS)
cloud and radiance fields. In approximate terms, 40 % (quality flag –
QF = 0, land or ocean) and 73 % (QF = 1, land or ocean) of the
observations are within 4 km of clouds. 3D radiative transfer calculations
indicate that 3D cloud radiative perturbations at this cloud distance, for
an isolated low-altitude cloud, are larger in absolute value than those due
to a 1 ppm increase in CO2. OCO-2 measurements are therefore
susceptible to 3D cloud effects. Four 3D cloud metrics, based upon MODIS
radiance and cloud fields as well as stand-alone OCO-2 measurements, relate
XCO2bc–TCCON averages to 3D cloud effects. This analysis indicates that the
operational bias correction has a nonzero residual 3D cloud bias for both
QF = 0 and QF = 1 data. XCO2bc–TCCON averages at small cloud distances
differ from those at large cloud distances by −0.4 and −2.2 ppm for the QF = 0 and QF = 1 data over the ocean. Mitigation of 3D cloud biases with a
table lookup technique, which utilizes the nearest cloud distance (Distkm) and
spatial radiance heterogeneity (CSNoiseRatio) 3D metrics, reduces QF = 1
ocean and land XCO2bc–TCCON averages from −1 ppm to near ±0.2 ppm.
The ocean QF = 1 XCO2bc–TCCON averages can be reduced to the 0.5 ppm level
if 60 % (70 %) of the QF = 1 data points are utilized by applying
Distkm (CSNoiseRatio) metrics in a data screening process. Over land the
QF = 1 XCO2bc–TCCON averages are reduced to the 0.5 (0.8) ppm level if 65 % (63 %) of the data points are utilized by applying Diastkm (CSNoiseRatio)
data screening. The addition of more terms to the linear regression
equations used in the current bias correction processing without data
screening, however, did not introduce an appreciable improvement in the
standard deviations of the XCO2bc–TCCON statistics.

Abstract. The precise measurement of the amount fraction of atmospheric nitrous oxide (N2O) is required to understand global emission trends. Analysis of the site-specific stable isotopic composition of N2O provides a means to differentiate emission sources. The availability of accurate reference materials of known N2O amount fractions and isotopic composition is critical for achieving these goals. We present the development of nitrous oxide gas reference materials for underpinning measurements of atmospheric composition and isotope ratio. Uncertainties target the World Metrological Organisation Global Atmosphere Watch (WMO-GAW) compatibility goal of 0.1 nmol mol−1 and extended compatibility goal of 0.3 nmol mol−1, for atmospheric N2O measurements in an amount fraction range of 325–335 nmol mol−1. We also demonstrate the stability of amount fraction and isotope ratio of these reference materials and present a characterisation study of the cavity ring down spectrometer used for analysis of the reference materials.

Abstract. The lower-thermosphere–ionosphere (LTI) system consists of the upper atmosphere and the lower part of the ionosphere and as such comprises a complex system coupled to both the atmosphere below and space above. The atmospheric part of the LTI is dominated by laws of continuum fluid dynamics and chemistry, while the ionosphere is a plasma system controlled by electromagnetic forces driven by the magnetosphere, the solar wind, as well as the wind dynamo. The LTI is hence a domain controlled by many different physical processes. However, systematic in situ measurements within this region are severely lacking, although the LTI is located only 80 to 200 km above the surface of our planet. This paper reviews the current state of the art in measuring the LTI, either in situ or by several different remote-sensing methods. We begin by outlining the open questions within the LTI requiring high-quality in situ measurements, before reviewing directly observable parameters and their most important derivatives. The motivation for this review has arisen from the recent retention of the Daedalus mission as one among three competing mission candidates within the European Space Agency (ESA) Earth Explorer 10 Programme. However, this paper intends to cover the LTI parameters such that it can be used as a background scientific reference for any mission targeting in situ observations of the LTI.
A modeling study of temporal and spatial pCO2 variability on the biologically active and temperature-dominated Scotian Shelf
Authors: Rutherford Krysten , Fennel Katja , Atamanchuk Dariia , Wallace Douglas , Thomas Helmuth
Published: February 2021

Abstract. Continental shelves are thought to be affected disproportionately by climate change and are a large contributor to global air-sea carbon dioxide (CO2) fluxes. It is often reported that low-latitude shelves tend to act as net sources of CO2 whereas mid- and high-latitude shelves act as net sinks. Here, we combine a high-resolution regional model with surface water time-series and repeat transect observations from the Scotian Shelf, a mid-latitude region in the northwest North Atlantic, to determine what processes are driving the temporal and spatial variability of partial pressure of CO2 (pCO2). In contrast to the global trend, the Scotian Shelf acts as a net source. Surface pCO2 undergoes a strong seasonal cycle associated with both a strong biological drawdown of Dissolved Inorganic Carbon (DIC) in spring, and pronounced effects of temperature, which ranges from 0 °C in the winter to near 20 °C in the summer. Throughout the summer, events with low surface-water pCO2 occur nearshore associated with coastal upwelling. This effect of upwelling on pCO2 is also in contrast to the general assumption that upwelling increases surface pCO2 by delivering DIC-enriched water to the surface. Aside from these localized events, pCO2 is relatively uniform across the shelf. Our model agrees with regional observations, reproduces seasonal patterns of pCO2, and simulates annual outgassing of CO2 from the ocean of +1.9 ± 0.2 mol C m−2 yr−1 for the Scotian Shelf, net neutral CO2 flux of −0.09 ± 0.16 mol C m−2 yr−1 for the Gulf of Maine and uptake by the ocean of −0.88 ± 0.4 mol C m−2 yr−1 for the Grand Banks.
Characterizing the oceanic ambient noise as recorded by the dense seismo-acoustic Kazakh network
Authors: Smirnov Alexandr , De Carlo Marine , Le Pichon Alexis , Shapiro Nikolai M. , Kulichkov Sergey
Published: February 2021

Abstract. In this study, the dense seismo-acoustic network of the Institute
of Geophysical Research (IGR), National Nuclear Centre of the Republic of
Kazakhstan, is used to characterize the global ocean ambient noise. As the
monitoring facilities are collocated, this allows for a joint
seismo-acoustic analysis of oceanic ambient noise. Infrasonic and seismic
data are processed using a correlation-based method to characterize the
temporal variability of microbarom and microseism signals from 2014 to 2017.
The measurements are compared with microbarom and microseism source model
output that are distributed by the French Research Institute for
Exploitation of the Sea (IFREMER). The microbarom attenuation is calculated
using a semi-empirical propagation law in a range-independent atmosphere. The
attenuation of microseisms is calculated taking into account seismic
attenuation and bathymetry effect. Comparisons between the observed and
predicted infrasonic and seismic signals confirm a common source mechanism
for both microbaroms and microseisms. Multi-year and intra-seasonal
parameter variations are analyzed, revealing the strong influence of
long-range atmospheric propagation on microbarom predictions. In winter,
dominating sources of microbaroms are located in the North Atlantic and in
the North Pacific during sudden stratospheric warming events, while signals
observed in summer could originate from sources located in the Southern
Hemisphere; however, additional analyses are required to consolidate this
hypothesis. These results reveal the strengths and weaknesses of seismic and
acoustic methods and lead to the conclusion that a fusion of two techniques
brought the investigation to a new level of findings. Summarized findings
also provide a perspective for a better description of the source (localization,
intensity, spectral distribution) and bonding mechanisms of the
ocean–atmosphere–land interfaces.

L’entre-deux identitaire dans les écritures migrantes : une rhétorique de la modernité
Authors: Tang Élodie Carine
Published: February 2021

Élodie Carine Tang, dont Le roman féminin francophone de la migration vient de paraître aux éditions L’Harmattan, poursuit ici ses intérêts de recherche axés sur les écritures migrantes, le roman féminin postcolonial, et les pratiques scripturales contemporaines, où deux perspectives de deux écrivaines québécoises de souche étrangère se croisent : Ying Chen dans Les lettres chinoises; et Marie-Célie Agnant dans La dot de Sara. Celles-ci appartiennent au courant de l’écriture migrante qui a considérablement marqué les champs littéraire québécois à la fin du xxe siècle. Ces deux textes de fiction mettent en scène des personnages aux prises avec la réalité de l’immigration. Il s’ensuit de ce contact avec l’ailleurs un dilemme qui oscille entre le deuil des origines, et l’ouverture à une nouvelle naissance. La fiction mime ainsi subrepticement la relation qui s’institue entre l’immigré et le pays d’accueil. Pour faire coexister ces différents espaces culturels les écrivaines créent une position médiane qui réconcilie ces voix dissonantes. Ainsi, dans ce contexte, l’entre-deux identitaire n’est plus vécu comme une fragmentation, mais plutôt comme un enrichissement qui rejaillit de l’échange harmonieux entre diverses appartenances. L’esthétique du métis témoigne dès lors d’une nouvelle rhétorique qui délaisse les lieux communs, les clichés, les sentiers battus et s’inscrit dans ce sens dans la modernité.

Published: February 2021

Durante los dos meses comprendidos entre el 15 de agosto y el 17 de octubre de 2019 se mantuvo activa una alerta sanitaria por listeriosis, causada por la contaminación de productos cárnicos de tres empresas de Andalucía. La crisis trascendió el ámbito andaluz y el 22 de agosto España lanzó una alerta internacional. El presente artículo analiza el tratamiento que elpais.com, lavanguardia.com y abc.es dieron a dicha crisis. Partiendo de la teoría del framing se ha analizado la evolución de los enfoques dominantes en los 425 textos informativos o interpretativos que los tres medios publicaron sobre el tema durante los dos meses mencionados. Asimismo, se ha estudiado la autoría de los textos y las fuentes principales de los mismos. Aunque el encuadre más empleado es el de “Consecuencias” (30%), el “Mitigador” -que busca atenuar la gravedad de los hechos- aparece en un 17% de las ocasiones.

El “nosotros” y el “otro” en el discurso de los medios tradicionales y comunitarios sobre los inmigrantes
Authors: Escudero Camila
Published: February 2021

Este artículo propone una reflexión a partir de los conceptos de “extranjero”, de Simmel (2005), y de “hombre marginal”, de Park (2017), en la construcción del discurso periodístico sobre el inmigrante en la actualidad. El objetivo es verificar cómo el conflicto de voces presente en los textos publicados por la prensa tiene especial relevancia en la imagen de “nosotros” y del “otro” y cómo aparece en los medios tradicionales y comunitario. La metodología utilizada es Análisis del Discurso aplicada a la noticia de un atentado contra inmigrantes bolivianos en São Paulo, en 2019. Destacamos que al establecer la relación entre “nosotros” y el “otro”, el discurso de los medios tradicionales privilegia las diferencias, trata al inmigrante como un extraño, que no forma parte de la cultura local, confinado a territorios y condiciones marginales. Tal imagen es deconstruida por el discurso producido por el medio comunitario, que resalta el acto de migrar como un proceso continuo, subjetivo de transformación e innovación.

Published: February 2021

Este artículo presenta una recopilación de investigaciones que abordan fenómenos de migración desde la comunicación, en especial la construcción de narrativas en las redes sociales digitales y espacio público digital como proceso de mediatización entre sociedades que en éste convergen. El artículo aborda tres diferentes líneas de investigación mediante las cuales se han analizado fenómenos de movilidad humana como la crisis de refugiados en Europa, en relación con la esfera pública digital, la construcción de narrativas y sus efectos en las audiencias que a su vez también participan en el desarrollo del fenómeno en términos comunicacionales. Por último, propone con la ayuda de estos enfoques una línea de investigación para el abordaje de eventos migratorios en América Latina, en específico en el de la Caravana Migrante o Éxodo Migrante que tuvo lugar en México y Centroamérica en el 2018 y que podría servir como guía para futuras investigaciones aplicadas al contexto de América Latina.

Published: February 2021

El objetivo del artículo es analizar la cobertura periodística sobre la repatriación de los migrantes latinoamericanos residentes en Chile, forzada por los efectos sociales y económicos de la emergencia sanitaria por COVID-19. Se desarrolla un análisis de contenido cualitativo respecto del mensaje periodístico entre los meses de abril a julio de 2020, mediante la identificación de los encuadres comunicativos utilizados por cuatro periódicos chilenos. Los resultados evidencian una tendencia hacia la atribución de responsabilidad y el interés humano de las noticias relacionadas con la crisis migratoria ocasionada por la pandemia, concluyéndose que los encuadres identificados describen la fragilidad de los migrantes latinoamericanos, frente a los efectos de la crisis sanitaria y la indefensión sufrida cuando perdieron sus puestos de trabajos, evidenciando atropellos a sus derechos humanos tanto del país receptor como de los países de origen, siendo necesario implementar políticas migratorias transnacionales que los apoyen en futuras crisis humanitarias.
Forest Tenure and Sustainable Forest Management: Drawing Lessons from the Literature
Authors: Sarfo-Adu Gordon Kofi
Published: February 2021

The quest to foster sustainable forest management (SFM) in the era of sustainable development goals has reignited the debate on forest tenure concerns. Land and forest tenure insecurity has remained a major underlying cause of deforestation in Africa, which suggests that addressing tenure issues could effectively foster sustainable forest management. Adopting theoretical literature and drawing lessons from related empirical works, this study examines the role of land and forest tenure in sustainable forest management drive. Among other things, the study discusses how land tenure promotes or inhibits sustainable forest practices. The study outlines how frustrating tenure regimes deprive the community of the needed benefits and subsequent untoward behaviour unleashed on forests. The study concludes that the idea of tenure rights and tenure security has implications on sustainable forest management and admonishes a robust tenure regime that upholds local 'people's access to and usage of forest resources without sinister machinations and subjugation of local people. The study contends that determined rights and their long-term security remain crucial in attracting the tenure holders to make a strenuous investment in SFM since investments in forestry usually are made for the long term. Among other things, the study recommends for clarity and long-term security of ownership and tenure rights regarding forest products; a need to promote capacity-building for administrators and rights holders to adopt a sustainable mindset in their exploitation of timber products; and a need to foster stakeholder participation.

Este artigo busca ressaltar a importância do passado para os ideais e anseios da sociedade que o interpreta e como ela o altera de maneira a adequá-lo aos propósitos de sua época e expor uma proposta de intervenção pedagógica. Utilizaremos como fontes históricas edificações religiosas erguidas no centro da capital da cidade de São Paulo no início do século XX que, ao contrário da tendência vigente de modernização da paisagem urbana da metrópole que vivia a efervescência cultural que iria gerar a Semana de Arte Moderna de 1922, tais prédios retornam ao passado da Idade Média. Analisaremos de que maneira tais construções poderiam ser compreendidas dentro dos ideais sócio-culturais da sociedade paulistana da época. Enquanto também servirão como referencial para se pensar nas reformulações e reapropriações do passado por certa temporalidade para fomentar debates e reflexões para o ensino de História
O Sábado de Legnano (1176): leituras nacionalistas e ressignificações neomedievalistas na política italiana contemporânea

O século XIX foi palco para a criação da identidade nacional italiana durante o movimento conhecido como Risorgimento que, para tanto, recorreu maciçamente a reinterpretações de acontecimentos ligados à Idade Média, tendo eleito a Liga Lombarda, a batalha de Legnano (1176) e Alberto da Giussano como símbolos essenciais à sua luta em prol da constituição da Itália como estado-nação. A partir de inícios da década de 1980, com a formação do partido político etnoregionalista de direita conhecido durante a maior parte de sua história como Lega Nord (1989-2013), estes símbolos foram ressignificados para adequarem-se ao objetivo da criação de uma nova nação, a Padania, que, segundo os partidários da Lega, seria sucessora da Liga Lombarda medieval. Todos os elementos históricos e ideológicos da mitopoiese orquestrada pela Lega são essenciais para a análise e compreensão dos usos neomedievalistas de sua obra-prima, o longa-metragem Barbarossa (2009), aqui analisado em múltiplas perspectivas.

Paideia Medieval e Mythopoeia: Filosofia e Literatura em Tolkien.
Authors: Klautau Diego Genu
Published: February 2021

O tema deste artigo concentra-se nas relações entre filosofia e literatura no ensaio On Fairy-stories do escritor inglês J.R.R. Tolkien (1892-1973). Apresentado como conferência em 1939 e publicado em 1947, o texto mostra a concepção do autor sobre o gênero literário conhecido como fairy-stories, as estórias de fadas, e buscamos considerar as possíveis mediações e referências filosóficas e teológicas em sua investigação. Os objetivos do artigo são: 1) evidenciar a teoria literária proposta por Tolkien como parte da tradição filosófica do realismo medieval, com correspondências conceituais em Platão, Aristóteles, Agostinho e Tomás de Aquino; e 2) demostrar uma contribuição original de Tolkien na valorização da imaginação e da fantasia como forma da contemplação como finalidade do esforço educativo, denominada paideia, dessa tradição filosófica. A metodologia utilizada é de revisão bibliográfica comparativa entre os autores, usando tanto o ensaio citado quanto as cartas pessoais de J.R.R. Tolkien, além das obras dos filósofos em questão e seus comentadores contemporâneos. A conclusão afirma a viabilidade dessa relação entre a paideia e a mythopoeia concebida por Tolkien como uma via contemplativa que valoriza o artesanato de mitos como meio de admiração pela realidade na perspectiva metafísica.

Authors: De Souza Adrise Ferreira , Basso Menna Barreto Gomes Zordan Paola
Published: February 2021

Este artigo ensaístico faz algumas relações entre a escola e as multiplicidades do ato fotográfico. Traz a figura do espelho quebrado como possibilidade para se pensar as fragmentações da contemporaneidade, contraposta à uma imagem ideal, que se apresenta de forma completa, ao estilhaço multifacetado. Aborda, o problema da reflexão na filosofia da diferença. Utiliza autores que seguem Deleuze, Guattari e Foucault, fazendo algumas considerações em torno do conceito de fora e da imagem enquanto força assignificante.
A representação cultural dos povos indígenas nos livros didáticos de História do sexto ano do Ensino Fundamental
Authors: Santos Junia Fior
Published: February 2021

No Brasil, a abordagem da temática indígena passou por alguns deslocamentos teóricos, na tentativa de discutir os motivos da exclusão social e cultural desses povos, bem como, as representações preconceituosas e estereótipos projetados por concepções ideológicas de cunho colonial. O livro didático é uma ferramenta de apoio ao desenvolvimento da educação formal, utilizado pelos professores no processo de ensino - aprendizagem, e por isso, deve conceber uma visão de mundo pautada no respeito à diversidade e diferenças étnicas. Nessa perspectiva, este trabalho discute a abordagem da representação dos povos indígenas nos livros didáticos da disciplina de História do 6º ano do ensino fundamental, tendo como objeto de análise os livros: “Estudar História: Das Origens do Homem à Era Digital” e “História: Sociedade e Cidadania”. A pesquisa busca analisar como os elementos textuais e imagens contemplam a diversidade étnica e diferenças dos povos indígenas brasileiros e como suas dinâmicas são apresentadas. Como aporte teórico metodológico utilizamos as considerações de pesquisadores que discutem a importância da abordagem da Lei nº 11.645/2008 nos livros didáticos. Destarte, é possível constatar que as imagens e textos presentes nos livros didáticos analisados, abordam de formas diferentes a cultura e a diversidade étnica dos povos indígenas, sendo possível perceber que ainda existem negligencias que comprometem a compreensão do conhecimento em relação aos povos indígenas. A qual precisa ser ressignificada.
Ensino de História e Educação Patrimonial em Rio Grande/RS: proposição de atividades no "jogo de escalas"
Authors: Pinto Matheus Balbueno
Published: February 2021

O texto apresenta considerações para o estabelecimento de relações práticas e concretas entre o ensino de História e a Educação Patrimonial no município do Rio Grande/RS, podendo elas serem utilizadas como base para replicações em outros contextos locais. A ideia passa por um breve esboço teórico e metodológico sobre a conceituação de patrimônio histórico cultural e a aplicabilidade da Educação Patrimonial, além do diálogo com a educação. O foco, então, centra-se no ensino de História a partir desses pontos e levando em consideração uma dinâmica no “jogo de escalas” entre o macro e micro. As relações estabelecidas se dão entre os conteúdos tradicionais do currículo escolar de História e os bens culturais rio-grandinos a serem percebidos com a metodologia da Educação Patrimonial na dinâmica entre escalas. Assim, o macro – representado pelos conteúdos curriculares – encontra o micro – representado pelos bens culturais – na vivência do ensino de História. Por fim, chega-se ao aspecto pedagógico do patrimônio a ser valorizado no ensino de História, a partir da oferta de uma base de material de apoio aos professores, beneficiando as áreas.
Currículo escolar, prática pedagógica e saberes disciplinares da História
Authors: Salles André Mendes
Published: February 2021

O presente texto objetiva refletir sobre as relações teóricas entre currículo, disciplina escolar, prática pedagógica e saber disciplinar, com foco para a História – acadêmica e escolar. Parte-se de uma perspectiva teórica crítica do currículo, que o entende como uma construção social negociada, enredada em relações de poder. Nesse sentido, assinala-se a necessidade de investimentos cada vez maiores em pesquisas acerca da História das disciplinas escolares, para que se compreenda como elas foram sendo socialmente construídas em cada contexto histórico, social, político, cultural e curricular de cada país e em cada momento específico, assim como as relações estabelecidas com os saberes disciplinares correspondentes e com a prática pedagógica.

Four species new to Poland (Bryocentria brongniartii, Tremella coppinsii, T. hypocenomycis, and Zevadia peroccidentalis), and eight species new to Białowieża Primeval Forest (Hypomyces chrysostomus, Hypomyces rosellus, Lachnellula resinaria, Peniophora lycii, Phellinus viticola, Phlebia subochracea, Pronectria anisospora, and Typhula quisquiliaris) were recorded.
New Records of Rare Hypogeous Fungi from Poland (Central Europe)
Authors: Mleczko Piotr , Kozak Maciej , Karpowicz Filip
Published: February 2021

Investigations carried out in recent years have provided new data on the localities of some rare hypogeous fungi in Central Europe. In this study, we present new localities of Leucangium carthusianum, Melanogaster luteus, and Rhizopogon melanogastroides, two of which are new for Poland. Sporocarps of L. carthusianum were found in seven new localities in mixed and coniferous forests in the Western Carpathians as well as in Sudetes. In Poland, the species was also recorded in a mixed forest in the Kraków-Częstochowa Upland. Fir, Abies alba, accompanied the fungus in almost all known localities. Three localities of M. luteus were found in the Polish Western and Eastern Carpathians in Alnus incana communities mostly associated with streams. Knowledge of the distribution of this species in Europe is incomplete due to the complicated taxonomic history; nevertheless, it is regarded as rare, despite its wide distribution. One new locality of R. melanogastroides recorded in the Tatra Mts, Western Carpathians, is the fourth known to date. This species is mostly associated with Pinus mugo in high mountain localities (the Alps, the Tatra Mts). In this study, detailed descriptions and illustrations of the macro- and micromorphological features of the species are provided.

Authors: Daniel Daniela F. S. , Panetta Jairo
Published: February 2021

A variedade de linguagens de programação paralela impõe o desafio de escolher uma linguagem apropriada para cada plataforma alvo. Utilizando métricas clássicas e recentes, este estudo preliminar compara linguagens de programação paralela com relação à produtividade de programação e à portabilidade efetiva do código. Utilizamos três versões paralelas do Jogo da Vida escritas em OpenMP, CUDA e Kokkos. Resulta que OpenMP e Kokkos requerem menor esforço de codificação do que CUDA, que OpenMP é a melhor escolha para execução na CPU e Kokkos é a melhor escolha para a GPGPU.

Authors: Susin Matheus M. , Wanner Lucas
Published: February 2021

In this work, we compared the precision, speed, and power consumption of the reciprocal square root of a single-precision floating point number, using different approximation techniques. We also devised an equivalent approximation for half-precision floating point numbers, and evaluated its performance across the whole range of positive non-zero 16-bit floating point values.
Parallelization of a Large-Scale Watersheds Hydrological Model using CPU and GPU
Authors: Freitas Henrique R. A. , Mendes Celso
Published: February 2021

Hydrological models are commonly employed to calculate water flows on rivers and watersheds for the analysis of extreme events in nature. Computations in these models can grow depending on the numerical method, and also on the spatial and temporal resolutions, thus affecting the model efficiency and utility. This work parallelizes the MGB hydrological model on either CPU with OpenMP or GPU with OpenACC, respectively, aiming at the improvement in performance by employing computing resources of an HPC system. An analysis of the sequential and parallel executions is presented together with the runtime, speedup, efficiency, and load balance achieved.
A Context-Aware Library for Mathematical Approximations
Authors: Castro Roberto Alejandro Hidalgo , Wanner Lucas
Published: February 2021

We have built a mathematical library that includes a series of functions with different implementations with varying precision. We couple this library with a system service that monitors the computer context, including energy consumption, and according to this context, using specified rules, dynamically changes the implementations used by the target applications. Our case studies show that our library can trade-off at most of 4% degradation in application quality up to 40% savings in energy consumption.
