Cryoablation using liquid nitrogen for metastatic lung cancers
Authors: Nomori Hiroaki , Yamazaki Ikuo , Adachi Takuya
Published: June 2022

Background
While the cryoablation for tumors has been conducted using argon gas, the present study conducted cryoablation using liquid nitrogen for metastatic lung cancers. The study aim is to evaluate the suitability of cryoablation using liquid nitrogen for metastatic lung cancer and to compare preserved pulmonary function according to the number of treated tumors.
Methods
This was a retrospective observational study including 68 patients with 121 metastatic lung tumors that were treated with cryoablation using liquid nitrogen between 2013 and 2019. The treatment was performed with a single 10-G cryoprobe under computed tomography with local anesthesia. To penetrate the tumor with cryoprobe under spontaneous breathing, a guide needle kit consisting of a 21-G guide needle and an 8-G stainless-steel coaxial system was used. Cryoablation was generally performed with repeating freeze and thaw for 3 cycles. Primary outcome was the local control and incidence of pneumothorax. Secondary outcome was whether preserved pulmonary function 6 months after cryoablation varied according to number of treated tumors.
Results
Cryoprobe could reach all of the 121 tumors under computed tomography. Median follow-up period was 32 months. Histological types were carcinomas in 95 tumors and sarcoma in 26. The 3-year local control rate was 73% in all tumors, and 96% and 46% in tumors <2.2 cm and ≥2.2 cm, respectively. While the local control was not different in tumors <2.2 cm between carcinoma and sarcoma (p=0.43), sarcoma showed significantly poorer local control than carcinoma in tumors ≥2.2 cm, of which 3-year local control rate was 18% and 62%, respectively (p<0.001). The incidence of pneumothorax was 25%. While the average preserved pulmonary function was 98±6% after cryoablation for 1 tumor, the treatment for multiple tumors was associated with significantly lower preservation of pulmonary function (p=0.002).
Conclusion
Cryoablation using liquid nitrogen would be one of the treatment methods for metastatic lung cancers <2.2 cm. Preserved pulmonary function declined significantly with an increasing number of treated tumors.
Estimating Climate Influence Of The Potential Covid-19 Pandemic Spreading In Algeria

Published: June 2022

This document aims to investigate the potential influence of climate on the spread of the COVID-19 pandemic, the direct and indirect effects of climate are felt all over the planet, although their magnitude and manifestations vary. According to estimates by the World Health Organization (WHO), climate change could be the cause of nearly 250,000 additional deaths per year worldwide between 2030 and 2050 (Word Health Organization, 2021). This study focused on examining the relationship between climate (Temperature, humidity, and wind speed) and hospitalizations due to COVID-19 in a well-selected sample of wilayas in Algeria. In this brief, we want to shed light on the likely course and geographic spread of the epidemic. The purpose of this article is to answer the main question of the study: We do this by examining the effect of climate (temperature, humidity, and wind speed) on hospitalizations due to COVID-19 in the wilayas of Algiers, Blida, Oran, Adrar, Setif and Tamanrasset. The choice of wilayas is based on the availability, quality, and consistency of the data required. Our analysis suggests that high temperature and humidity or high relative wind speed tend to hamper the spread of the virus and that a high population density tends to facilitate its transmission. This does not mean that higher temperatures are enough to contain the disease. The climate potentially plays a role in the spread of many respiratory viruses. It appeared important to know if this could also be the case for the new coronavirus, COVID-19. While the role of climate in the transmission is still difficult to quantify, it is clear that other factors are taken into account in the transmission of COVID-19, namely mainly compliance with the rules of physical distancing and barrier gestures. This study focused more particularly on the effects of absolute climate (Temperature, humidity, and wind speed). 90% of infections would have occurred in areas where the temperature is between 3 and 17 degrees and the absolute humidity is between 4 and 9 g / m3, 35 to 85% relative humidity (Bukhari Q., Jameel Y., 2020). We address the issue of the impact of climate on the spread of COVID-19, we use the SUR (Seemingly Unrelated Regression) model to estimate the relationship between climate and COVID-19 cases in Algeria during the period between April 18th, 2020, and April 17th, 2021 inclusive. The results of the SUR model estimate, also showed that there is no real climate that can damage the pandemic situation in Algeria during the period studied.

EXTRACTION OF TEXTILE DYES USING TWO-PHASE AQUEOUS SYSTEMS COMPOSED OF 2-PROPANOL AND SULFATE SALTS. Aqueous Two Phase Systems (ATPS) composed of 2-propanol + inorganic salt (Na2SO4/MgSO4) + water, at different temperatures T = (20, 30, 40 and 50) °C were applied in the partition studies of the textile dyes Yellow, Blue Royal and Red Dianix CC. The thermodynamic parameters of the free transfer energy (ΔGtr), enthalpy (ΔHtr) and entropy (ΔStr), respectively, were determined for dye partitioning, using the Van’t Hoff equation. The values of the partition coefficients of textile dyes Yellow, Royal Blue and Red Dianix CC, ranged from 14.21 to 1610.00, 15.15 to 994.00 and 17.32 to 311.75, respectively; and with dye extraction yields ranging from 93.17 to 99.93; 94.53 to 99.89 and 97.19 to 99.64, respectively. Based on the ΔGtr results, it was verified that the dyes partition process was thermodynamically spontaneous, in all evaluated systems. For the 2-propanol + sodium sulfate ATPS, there was a prevalence of the enthalpic contribution over the entropic contribution (ΔHtr > ΔStr), while for the 2-propanol + magnesium sulfate systems, a greater predominance of the entropic contribution was observed (ΔHtr < ΔStr). The recovery yields (Y) values obtained were above 90% for all systems.
The vibration of a thermoelastic nanobeam due to thermo-electrical effect of graphene nano-strip under Green-Naghdi type-II model
Authors: Youssef Hamdy M. , Al Thobaiti Abdullah A.
Published: June 2022

In this paper, a new analysis of thermoelastic, homogeneous, and isotropic nanobeams has been constructed in the context of the Green-Naghdi type-II heat conduction law. The first end of the nanobeam is based on a graphene strip, which contains an electrical current with a small voltage which is a novel application. Under simply supported boundary conditions with fixed side ratios, the nanobeam has been thermally loaded with a heat source due to the thermal effect of the electrical current. On the time variable, the Laplace transform technique was utilized to solve the governing differential equations. The solutions were computed in the Laplace transform’s domain. Tzou’s approximation technique based on an iteration formula was used to calculate the Laplace transform inversions numerically. The numerical findings for various values of the electrical voltage and electrical resistivity of the graphene nano-strip have been displayed using graphs illustrating distinct scenarios. All the nanobeam’s researched functionalities have been reported to be influenced by electrical voltage and electrical resistivity. The electrical voltage and resistivity of a graphene nano-strip might be utilized as a tuner to regulate the nanobeam's vibration and energy.

Published: June 2022

For companies to be able not only to survive, but also to differentiate themselves in the current global market scenario, all their functional areas must be in line with short, medium, and long-term management objectives and policies. The performance and competitiveness of companies depend on the behaviour of their production system, so an ambitious and adequate maintenance management is necessary. In this way, companies seek to adopt new methodologies and approaches to maintenance management that allow them to prepare maintenance for the challenges of Lean Philosophy and Industry 4.0. The Lean philosophy aims to do more and more with less and less, that is, using less equipment, less human effort, less space, and time, trying to offer customers exactly what they want, at the right time. On the other hand, Industry 4.0 is based on intelligent factories with production processes with a computer interface between people, machines, and resources, through extensive communication networks that combine the virtual and the real world, to obtain all integrated processes generating thus a real-time information system. Thus, an adequate maintenance management system contributes not only to improve maintenance performance as well as the production system. The maintenance management system, when combined with Lean Philosophy and Industry 4.0 concepts, makes it more efficient and effective. To improve maintenance performance, a system that combines these three concepts is proposed.

Published: June 2022

O objetivo deste trabalho foi analisar a composição florística e a riqueza de espécies arbóreas regenerantes em um fragmento de floresta atlântica de Jaboatão dos Guararapes, Pernambuco. Foram instaladas 40 parcelas de 10 m x 10 m, sendo 20 em cada ambiente (borda e interior da floresta), totalizando 4.000 m2 de área amostral. Foram catalogados e identificados todos os indivíduos com altura igual ou maior que 1,0 metro e circunferência à altura do peito a 1,30 m do solo, menor que 15,0 cm. Registraram-se 123 espécies, pertencentes a 38 famílias e 74 gêneros. Em todo o fragmento, Fabaceae, Myrtaceae e Melastomataceae apresentaram o maior número de espécies, enquanto os gêneros Miconia e Myrcia foram mais representativos tanto na borda como no interior da floresta. Os ambientes de borda e interior florestal apresentaram H’ = 3,59 e 3,40, J’ = 0,80 e 0,76 e D’ = 0,04 e 0,05, respectivamente, e o índice de similaridade de Sorensen foi de 0,64 para os ambientes pesquisados. Pode-se inferir que o fragmento estudado possui elevada riqueza e diversidade de espécies, evidenciando alta heterogeneidade ambiental e baixa dominância ecológica.

Authors: Maurício Shoji Seki  , Renato Muzzolon Júnior  , Renann de Silos Vieira
Published: June 2022

A restinga assume grande importância no litoral brasileiro. A ocupação costeira pelo homem tem comprometido esses ambientes. No Espírito Santo, sobretudo na capital capixaba, o principal fator degradante consiste no desenvolvimento urbano. Este trabalho visou avaliar o impacto da ampliação do aeroporto de Vitória, no contexto da ecologia da paisagem, focando manchas de vegetação predominantemente naturais. Utilizaram-se técnicas de fotointerpretação e vetorização das imagens de satélite referentes a maio/2005, setembro/2009 e agosto/2017, em alusão ao início, meio e fim das obras aeroportuárias. Vetores foram convertidos em raster e tratados no programa Fragstats, que mensura a dinâmica das modificações na paisagem. A comparação temporal demonstrou o quão impactante foi o empreendimento, de tal modo que a classe complexo de restinga teve a métrica (mensuração) de área diminuída em 42% e deixou de ser a feição dominante da paisagem, sendo substituída por perímetro urbano (incremento de 7%) e, ainda, superada por infraestrutura aeroportuária (210% de aumento). A cobertura vegetal sofreu retração de 74% na área-núcleo e acréscimo de 30% no índice de forma, enquanto o resultado de vizinho mais próximo apresentou variação decorrente da fragmentação da flórula. O empreendimento interferiu demasiadamente na espacialização da restinga, alterando as proporções da composição paisagística.

Authors: Suzelaine Aparecida da Silva Matos  , Glauce Portela de Oliveira
Published: June 2022

There is little information on the cultivation of species with ornamental potential in Mato Grosso. The aim of this work was to evaluate, in Varzea Grande (MT), the favorable environment for the production of Dahlia pinnata Cav. and the quality of the seeds sold for this purpose. The experiment took place at the Seed Laboratory and at the experimental field of Varzea Grande University Center (Univag), Mato Grosso. Seeds of this species were purchased in commercial packaging. The seeded materials were arranged in the greenhouse with 50% shading (Sombrite®) and in full sun, both with daily irrigation. Growth assessment was performed from the seventh day after emergence. The number of emerged plants was evaluated from the first week after sowing until the establishment of seedlings.Analysis of variance was performed by Tukey test at 5% and regression analysis. The germination test showed 71% of normal seedlings, a lower value than the minimum germination described in the package, and emergence and establishment of 32% of the seedlings. The evaluated conditions, in greenhouse under 50% shading, were favorable to the production of Dahlia pinnata, even when commercial seeds presented low germination potential

Published: June 2022

Para a abelha sem ferrão uruçu-amarela (bugia), não se conhecem os limiares climáticos para o movimento externo. Visando obter informações sobre a influência dos fatores abióticos na atividade de voo, observou-se o movimento externo de três colônias, durante um ano. Em cada colônia, a cada hora, durante dez minutos, foram contabilizadas as abelhas que saíam sem nada ou com detritos e aquelas que entravam com pólen, resina, barro, sem carga e com o abdome dilatado (água ou néctar), desde o início das atividades até o cessar, ao longo do dia. Os limites horários de atividade verificados foram 4h54 (primavera) e 19h (primavera e verão) e 5h30 (outono) e 18h30 (outono e inverno), realizando 13 horas de atividade durante o outono/inverno e 14 horas durante a primavera/verão. A amplitude de temperatura para a atividade foi de 12 a 41ºC; para umidade relativa, de 39,5 a 100%. O recurso mais coletado foi o néctar (durante as quatro estações), seguido pelo pólen. Resina e barro foram coletados em temperaturas mais elevadas do que pólen e néctar. O movimento externo mostrou correlação negativa com a temperatura e positiva com a umidade relativa. As abelhas foram observadas saindo no escuro e também com chuva.
Aplicação de biotecnologia vegetal para padronização de plantas ornamentais
Authors: Fernanda Kelly Mezzalira
Published: June 2022

A clonagem é uma ferramenta utilizada para propagar materiais vegetais, garantindo que as plantas regeneradas sejam geneticamente idênticas à matriz desejada. Sabe-se que o setor de plantas ornamentais contribui de maneira expressiva com a economia e que, entre as plantas ornamentais de mais estima entre os brasileiros, estão as orquídeas. O objetivo do presente trabalho foi estabelecer um protocolo de assepsia eficiente para meristemas laterais e de obtenção de clones da orquídea do gênero Phalaenopsis. Para a metodologia, visando à padronização de um protocolo de assepsia, foram elaborados e testados quatro tratamentos com diferentes combinações (concentração × tempo) de agentes como hipoclorito de sódio, álcool, cobre, tween e lavagem dos explantes. Os meristemas foram retirados do caule das plântulas, de suas hastes florais. Os resultados obtidos mostram que nenhum tratamento para assepsia testado aqui apresentou resultados significativos e positivos. Desse modo, não se pôde estabelecer, ainda, um protocolo de assepsia para meristemas laterais de orquídeas do gênero Phalaenopsis, uma vez que todos os meristemas sofreram contaminação e oxidação. Logo, ainda não foi possível obter clones por essa metodologia. O presente trabalho serve como base inicial para futuras pesquisas referentes à clonagem por meio de meristemas em Phalaenopsis.

Published: June 2022

Verificou-se a influência dos fatores edáficos sobre as comunidades vegetais no continuum manguezal-floresta ombrófila densa, na Baía Babitonga, Santa Catarina. Foi adotado o método de parcelas de 5 × 5 m para as comunidades arbóreas e de 1 × 1 m para as comunidades campestres, obtendo-se a frequência e/ou a cobertura das espécies ocorrentes. Foram instaladas 30 parcelas em seis transecções, abrangendo todo o continuum. Foi realizada a coleta de três amostras compostas, por transecto, para caracterizar o solo de cada ambiente, além da análise de agrupamento tipo cluster hierárquico para verificar a relação entre as espécies e as feições de sua ocorrência. A mesma análise foi utilizada no que se refere às variáveis do solo. Empregou-se a análise de variância (ANOVA) para comparar as médias das variáveis edáficas. A análise de componentes principais (PCA) foi usada a fim de verificar o peso das variáveis edáficas. Nas seis feições do continuum, foram identificadas 28 espécies (24 gêneros, 16 famílias – Myrtaceae e Melastomataceae foram as de maior riqueza). A PCA explicou 72,88% do conjunto de dados, com destaque às variáveis de fertilidade do solo. A ANOVA indicou a salinidade como variável formadora de gradiente ambiental. Os agrupamentos formados pelas plantas e pelo solo separaram as feições do continuum, sendo as comunidades vegetais fortemente relacionadas às variáveis edáficas.

Published: June 2022

O padrão de voo dos insetos está relacionado principalmente ao acasalamento e à obtenção de alimento, sendo, em ambientes naturais, uma atividade dinâmica que envolve fatores bióticos e abióticos. O objetivo do presente trabalho foi realizar um levantamento qualitativo e quantitativo dos coleópteros presentes em uma área de mata nativa, caracterizando e delimitando a altura preferencial de voo das principais espécies. Foram instaladas armadilhas de interceptação de voo em área pertencente ao Centro de Pesquisa em Florestas, Santa Maria, Rio Grande do Sul, no período de julho de 2011 a julho de 2012. As armadilhas foram distribuídas em diferentes alturas (0,5; 1; 1,5; 2; 2,5; 3; 3,5; 4; 4,5; 5; 5,5 e 6 metros acima da superfície do solo), com três repetições e distantes 30 metros entre si. Foram coletados 7.201 espécimes, distribuídos em 34 famílias e 116 morfoespécies. Capturaram-se em maior abundância: Euetheola humilis e Harmonia axyridis, na faixa de 0,5 a 1 metro; Bostrychopsis uncinata, entre 0,5 e 1,5 metro de altura; e Neoclytus ypsilon, Pherhimius fascicularis, Gibbifer adrianae e Martinsellus signatus, a 0,5 metro. Desse modo, concluiu-se que o intervalo situado entre 0,5 e 1,5 metro é o ideal para avaliar coleópteros em área de mata nativa.

Published: June 2022

Foi estudada a influência dos fatores abióticos sobre a atividade externa de Melipona bicolor schencki, em Santa Catarina, pela observação do movimento externo, por 12 meses, com registro da temperatura e da umidade relativa. As atividades iniciaram[1]se mais tarde no outono e no inverno (6h34 e 6h15) e mais cedo na primavera e no verão (4h48 e 4h55) e finalizaram mais tarde na primavera e no verão (19h15 e 18h54) e mais cedo no outono e no inverno (18h02 e 18h). Na primavera, as abelhas voaram por 14 horas, no verão por 13 e no outono e no inverno por 12. Os limiares de temperatura para início de atividade foram, na primavera e no verão, 19 e 16ºC e, no outono e no inverno, 12 e 14ºC, e os de umidade relativa foram, na primavera e no outono, 40 e 31% e, no verão e no inverno, 47%. Ocorreram atividades de 12 a 39ºC e de 31 a 97% de umidade relativa. Em todas as estações, a maior coleta foi de néctar e/ou água, seguida da de pólen. Só houve coletas de barro e de resina e remoção de detritos acima de 20ºC. As correlações para temperatura foram majoritariamente negativas, e para umidade relativa, positivas.

As estimativas de parâmetros genéticos permitem mensurar a variabilidade genética existente em uma população e, associadas às análises de correlações, constituem uma das etapas iniciais em um programa de melhoramento genético para quaisquer culturas. Objetivou-se estimar os parâmetros genéticos e correlações de caracteres agronômicos de nove genótipos de girassol cultivados sob condições edafoclimáticas do semiárido norte mineiro. O experimento foi conduzido em delineamento experimental de blocos casualizados, com quatro repetições. Foram avaliadas as seguintes variáveis: stand, altura de planta, data de floração inicial e da maturação fisiológica, curvatura do caule, tamanho do capítulo, massa de mil aquênios e produtividade. Os resultados demonstraram que correlações positivas e significativas foram encontradas entre variáveis de interesse agronômico, tais como altura de planta, massa de mil aquênios e produtividade, correlações que, aliadas à alta herdabilidade encontrada para os caracteres analisados, sugerem o valor fenotípico como uma medida confiável para a seleção de genótipos superiores.

Published: June 2022

Amylase production from starch sources is associated with the nature of this carbon source, particle size and crystalline architecture of natural starch granules. The aim of this work was to evaluated the amylase production by Saccharomyces diastaticus ATCC 13007, using different CaCO3 concentration and corn starch (Zea mays) and cassava starch (Manihot esculenta) as inducers. A 22 Central Composite Rotatable Design with three replications at the center point was used to determine the influence of calcium and starch concentrations on the production process. Besides, the partial characterization of the crude enzymatic extracts obtained was investigated. Ca2+ influenced the α-amylase production by both evaluated carbon sources. The production of glucoamylase was not influenced by the variables under study. Partial characterization of crude extracts indicated that, for corn substrate, the enzyme showed maximum activity at pH 5.0, and no influence of temperature was observed. Regarding cassava starch, the results showed that conditions at central point (pH 6.5 and 50ºC) should be avoided in order to maximize enzyme activity.

Published: June 2022

The objective of the present work was to analyze the influence of zinc doses on biomass production, root biometry and photosynthesis in Pfaffia glomerata plants. A genotype of the species was used to obtain the seedlings through in vitro propagation. In a greenhouse, the plants were cultivated, using four doses of Zn as treatment: 0.5; 50 75 and 100 µM. The nutrient solutions were applied for 84 days, at the end of which photosynthetic parameters and biomass production were analyzed. From the root system, 25% were frozen for further analysis of root biometry. Data were subjected to statistical analysis using the Scott-Knott test with a 5% significance level. It was observed that the production of fresh biomass was reduced mainly in the aerial part for the treatments of 75 and 100 µM. Root length, surface area and volume were reduced in the 50 and 75 µM treatments. The transpiration and assimilation rate, stomatal conductance, water use efficiency, carboxylation efficiency, were the affected photosynthetic parameters. Visibly, the plants showed variation in leaf color. It is concluded that P. glomerata tolerates small excesses of Zn, managing to survive under these conditions, despite showing small changes in its growth and development.
Polinizadores apícolas (Hymenoptera, Apoidea) do mirtilo (Vaccinium ashei Read variedade Climax, Florida e Bluegem) no norte de Santa Catarina, Brasil
Authors: Allison L. Tietz  , Denise M. D. S. Mouga
Published: June 2022

O mirtileiro Vaccinium ashei (Ericaceae), nativo do Hemisfério Norte, requer cerca de 500 horas de frio (temperaturas inferiores a 7,2ºC) para superar a dormência. Em Santa Catarina, o município de Campo Alegre é apropriado para a fruticultura de clima temperado. Visando conhecer as relações de polinização, verificaramse diferenças morfológicas de três variedades de mirtileiros: Bluegem, Climax e Florida. A apifauna visitante foi coletada para identificação. Realizaram-se cinco campanhas de coletas (35 horas de amostragem). Colheram-se 10 frutos de cada variedade estudada (para peso, medida horizontal e vertical). Foram amostrados 832 indivíduos de abelhas, de 14 táxons e três famílias (Andrenidae, Apidae e Halictidae). Das espécies coletadas, as abelhas nativas que têm potencial para polinização do mirtileiro são as do gênero Plebeia, que podem entrar na flor, assim como espécies pequenas de Halictidae, que têm capacidade de fazer buzzing, característica esta também das abelhas Bombus morio e B. pauloensis. A variedade Climax recebeu mais táxons de abelhas (10) do que as outras variedades (Florida, 8; Bluegem, 7). O peso das frutas e as medidas horizontal e vertical das três variedades mostraramse significativamente diferentes, em diferentes combinações. Beija-flores foram observados visitando as flores do mirtileiro.

'Quanto mais histórias, mais novelos' ou os fios de outra Xerazade Sobre narrar os trânsitos migrantes e a condição exílica de voluntários e refugiados em 'Um muro no meio do caminho', de Julieta Monginho
Authors: Valentim Jorge Vicente
Published: June 2022

A partir da percepção do gesto de narrar, enquanto exercício afirmativo de uma ação bem ao gosto da personagem-narradora Xerazade, tal como postulado por Isabel Pires de Lima (2012), pretende-se, nesse artigo, refletir sobre os trânsitos mobilizados na tessitura narrativa do romance de Julieta Monginho, Um muro no meio do caminho (2018). Assim, se, por um lado, a narradora-protagonista J. desloca-se para a Grécia para desempenhar uma atividade humanitária, é essa mobilidade que a faz encontrar outros sujeitos em um trânsito forçado: os refugiados.  Ao resgatar cada figura em Chios, J. configura-se como uma autêntica Xerazade, num duplo movimento de contar as histórias (Benjamin, 1985). Enquanto voluntária, ela própria se coloca numa condição movente, ao mesmo tempo, que, como ouvinte das narrativas dos refugiados, capta a condição exílica a que são expostos (Nouss, 2016). Nas duas feições (voluntários e refugiados), as personagens entrecruzam suas histórias, com seus problemas e suas complexidades, permitindo-se vislumbrar, enquanto figuras de movimento (Ette, 2016). Sem cair, no entanto, na armadilha de apontar soluções fáceis, este exercício de uma Xerazade inquieta chama mais a atenção para um questionamento constante do problema, justamente porque narra para que ele não desapareça e não sucumba diante da indiferença.

A partir das traduções das crônicas de Arkadi Aviértchenko (“A Tragédia do Escritor Russo”, 1920) e de Teffi (“Que Faire”, 1920e“A Cidadezinha”, 1927) que acompanham o artigo, pretende-se analisar algumas questões que marcaram a primeira onda da emigração russa como isolamento; a ideia da recriação da Rússia no exterior e a perda gradativa das memórias e referências culturais e linguísticas. O gênero crônica parece especialmente propício a essa análise, uma vez que, por transitar entre ficção literária, registro histórico e jornalismo, permite capturar as impressões imediatas da primeira onda da emigração russa que se deu após a Revolução de 1917 e a Guerra Civil subsequente. Tomadas sob a ótica das epopeias mitológicas, as crônicas de Aviértchenko e Teffi revelam também o exílio naquele momento, para os russos, como uma espécie de viagem para o mundo além-fronteiras, em que tudo é virado às avessas. Em última perspectiva, essas narrativas remetem a uma tragédia humana universal, que é o encontro com o ‘outro’, com o estranho. No entanto, no plano ficcional, a angústia e a insegurança relacionadas ao exílio são ressignificadas por meio da ironia e da subversão grotesca, inclusive no nível linguístico, em que ocorrem combinações das mais inusitadas entre o idioma russo e francês.

A estrutura fílmica de "Prazer, Camaradas!" (estreado no Festival de Locarno em Agosto de 2019, e que, a meu ver, está para além do documentário) é uma narrativa que entretece vozes, tempos e espaços distintos, numa espécie de "mise-en-abyme", trazendo para o presente personagens, eventos, episódios e a História propriamente dita, de um passado recente, com cerca de 40 anos de existência.

Published: June 2022

El Valle del Sinú es una subregión en donde se concentra la mayor área de siembra y producción de maíz en Colombia. En esta subregión los rendimientos del cultivo en los últimos años han presentado un estancamiento, a pesar de contar con tecnologías y condiciones agroecológicas aptas para su desarrollo y productividad. Se presume que el laboreo continuo de los suelos a través de los años, ha generado un alto grado de deterioro físico y químico de sus propiedades, por lo que la presente investigación se llevó a cabo con el objeto de realizar un diagnóstico de la fertilidad medida por algunas propiedades físico-químicas del suelo. Se realizó un muestreo en 80 predios, en donde continuamente se vienen sembrando cultivos de maíz, en rotación con algodón. Los resultados de las evaluaciones indicaron que desde el punto de vista químico en general los suelos presentan una fertilidad adecuada para el desarrollo y productividad del cultivo, sin embargo, se observó algún grado de deterioro de las propiedades físicas, evidenciado por características como la densidad aparente, la infiltración básica y la distribución de raíces en el perfil, condicionadas principalmente al tipo de labranza que se ha venido practicando. Lo anterior probablemente ha venido afectando el crecimiento de las raíces, la libre circulación de agua y gases, y la nutrición del cultivo de maíz. Se recomendó un estudio más detallado de la distribución de las raíces en el perfil del suelo a fin de proponer estrategias para su recuperación.

The importance of qualification and training of lay people in Basic Life Support (BLS) leads to a reduction in deaths or irreversible sequelae in the population affected by a Cardiopulmonary Arrest (CPA), because in most emergency cases whoever is close is not a health professional. The purpose of this article is to analyze the importance of qualification and training in Basic Life Support for lay people. This is a descriptive, qualitative study carried out through an integrative literature review (ILR). To carry out the bibliographic review, searches were carried out in the following databases: repositories of Universities, Virtual Health Libraries, PubMed, Journals, Magazines, Federal Laws and Ordinances Scientific Electronic Library Online (SCIELO) and Online System of Search and Analysis of Literature Medical (MEDLINE). Articles related to the theme of the project, articles with Portuguese language, online and free access to the full text and from the year 2014 were included. The studies that constituted the units of analysis have a variety of authors, publication sources and countries of origin of the studies. The training and qualification of the BLS is of relevance for the knowledge of the lay population and should be applied even in the school phase, with theoretical-practical methods and repeated annually, for a better effectiveness in the initial care of a victim in CPA.
Adoptees and Americans: Exporting Hans Christian Andersen and Karen Blixen (Isak Dinesen)
Authors: Juncker Clara
Published: June 2022

Hans Christian Andersen and Karen Blixen (aka.) Isak Dinesen have been widely read in America, with Hollywood’s Out of Africa adaptation adding to the attention. Both writers dramatized their alienation with adoption stories reaching across national and racial boundaries. They became iconic writers in the US for many reasons, but their preoccupation with adoption has been insufficiently explored. In fact, their transnational, transracial, transsexual, and cross-species adoption tales have entered US conversations about the Other, since the adoptee arrives in familial structures from “other” ideological, economic, or racial locations. Their adoption tales further fit American rights discourses, by insisting on the rights of belonging and conditions of freedom laid down by reason and law. They also subscribe to emotional discourses that evoke in the audience empathy and emotions related to dignity and humanity. Fairy tale adoptions fit the classic American quest narrative—Huck Finn-style—in which a heroic protagonist takes off into the unknown to find an identity, rooted in liberty, independence, and freedom. In a 21st-century world populated by migrants, refugees, orphans, adoptees, adoptive parents, and adopted or adoptive nations, Andersen and Blixen communicate with global adoption narratives the need for new ideological constellations of family, community, and nation.

Published: June 2022

Although mid- and long-term outcomes after the Ross procedure for aortic
valve disease have been increasingly improving over the years, this is
still a rather challenging operation in neonates and small children.
This is particularly true for patients with associated congenital heart
defects and critical clinical conditions. Herein we describe the
application of this procedure as a rescue operation in emergency
circumstances in a low-birth-weight neonate with severe aortic stenosis,
aortic regurgitation and mitral regurgitation after a previous aortic
coartectomy.

Introduction: Catheter ablation of atrial fibrillation (AF)
and/or atrial tachycardia (AT) in heart failure (HF) patients provides
improvement in symptoms cardiac function and survival. However, these
procedures remain challenging with higher recurrence and complication
rates compared to patients with normal cardiac function. We aimed to
compare outcomes of AF/AT ablations guided by an ultra-high density
mapping system between HF patients and controls. Methods and
results: Primary endpoint was the one-year recurrence rate of AF/AT. We
retrospectively examined all Rhythmia™-guided procedures performed in
Caen and Toulouse University Hospitals between 2015 and 2018 for AF/AT.
Patients with reduced left ventricular ejection fraction (LVEF) (i.e.
<50%), or with preserved LVEF and signs/symptoms of HF were
constituted the HF group and were subsequently classified in two
subgroups of HF patients with preserved (HFpEF) or reduced/mildly
reduced (HFrEF) LVEF. 246 patients were included, 135 in the HF group.
At one-year, 71 patients had experienced AF/AT recurrences, with no
difference between HF group versus non-HF group (31.9 vs 25.2%
respectively, p=0.262). AF/AT recurrence rates were not different
between HFpEF and HFrEF subgroups (37.1 vs 26.4% respectively,
p=0.196). In multivariate analysis, patients with mitral regurgitation
(p=0.011), hypertrophic cardiomyopathy (p=0.011) and persistent AF
(p=0.02) were at higher risk of recurrence. AF/AT recurrence was not
significantly associated with HF hospitalization (p=0.078) but HF status
was the only independent predictive factor of HF hospitalization
(p=0.002). Patients in the HF group showed significant improvement in
both their NYHA class and LVEF than non-HF patients. After ablation
procedures, while patients with HFrEF and HFpEF showed similar NYHA
class improvement, LVEF only improved in HFrEF patients. The rate of
complications were comparable in both groups. Conclusion:
Clinical outcomes of AF/AT ablations guided by UHD mapping system appear
similar in HF and non-HF patients. During the follow-up period, patients
with HF exhibit improvement of NYHA status and LVEF.
Vital rates contribute differently to impacts of competition on population growth
Authors: Lyu Shengman , Alexander Jake
Published: June 2022

Competition is among the most important factors regulating plant
population and community dynamics, but it is not well understood how
different vital rates respond to competition and jointly mediate
competitive population dynamics and species coexistence. We used
integral projection models (IPMs) to model the population growth of 112
pairwise combinations of 14 competing herbaceous plant species across an
elevation gradient (n = 324 IPM models in total). We showed that the
response of individual growth and seedling establishment contributed
most strongly to competition-induced declines in population growth
compared to survival, flowering probability and fecundity that
frequently showed complementary responses that occurred in 92% of
species pairs. Complementary responses significantly promoted population
growth under competition by 22% on average and strengthened species
coexistence. Our study emphasises the need to investigate demographic
processes to better understand competitive population dynamics and
species coexistence.
Diversity of bird species and their potential ecological roles in habitat maintenance on the wild coast of the Eastern Cape Province, South Africa

Birds provide important ecological services for the maintenance of
ecosystems’ integrity. However, there is limited research on ecological
roles of different bird species in maintenance of habitats in South
Africa yet many bird species are experiencing continuous conservation
threats. In this study, we aimed to document the diversity of bird
species in South Africa’s Wild Coast nature reserves, and to determine
potential role of each bird species in habitat maintenance using bird
feeding mode classifications as a species function’s proxy. Bird
observations were conducted afield over four years (2017 to 2020). Over
864 hours of field sampling in 2017-2020, we accumulated 818 bird
records containing 178 different bird species classified into 58
families. Shannon-Wiener Diversity Indices showed very high overall
species diversity, and across the nature reserves (H > 3.5)
with however, all nature reserves being non-significantly different. We
noted 32 bird species representing 30 families occurring across four
nature reserves with Silaka Nature Reserve having significantly more
diverse bird families than Mkhambathi Nature Reserve while not
significantly different to others. Forest bird species were more
dominant (42.1%; N = 178) throughout observations than other habitat
species. Annual bird species diversity across the observation years
remained very high (H > 3.5) with non-significant
differences across the years. However, the year 2018/2019, showed
significantly higher abundance of birds across all nature reserves.
Among different feeding modes, potential seed dispersers had a
significantly greater number of records than other groups while
pollinators were not significantly different in number compared to seed
predators. A non-significantly different number of birds in medium to
large size body size classes suggest availability of a variety of both
pollinators and subsequent seed dispersal vectors. Consistent with other
studies, conservation status and implications of bird species loss on
sustainable vegetation integrity must be prioritised.
Assessment of watercourses in terms of their impact on flood hazards: a case study from a mountain river basin
Authors: Solín Ľubomír , Madajová M. Sládeková , Michaleje L.
Published: June 2022

The aim of this case study is to present a methodological approach for
the flood hazard assessment of small watercourses, based on the
evaluation of the impact of the morphology of the watercourse channel,
land cover of the floodplain, transport infrastructures along the
watercourse, bank and channel vegetation, negative attributes of
vegetation, and debris in the channel. Each variable is represented by a
set of attributes that characterise the current state of the watercourse
reach. The assessment process begins with the division of watercourses
into river reaches based on a mutual combination of variables
influencing the flood hazard. Subsequently, the current state of the
variable attributes of each river reach is identified and their impact
on flood hazards is then assessed according to rational rules. The
impact of the individual attributes is first expressed on an ordinal
scale, which is then transformed into a quantitative weight. The overall
Flood Hazard Index (FHI) of the river reach is then determined through
the aggregation of the quantitative weights of the impact of individual
attributes. Key words: Flood hazard index, watercourse attributes,
municipality, riverine landscape, river reach
