Abstract. Reactive oxygen species (ROS) carried or induced by particulate matter (PM) are suspected to induce oxidative stress in vivo, leading to adverse health impacts, such as respiratory or cardiovascular diseases. The oxidative potential (OP) of PM, displaying the ability of PM to oxidize the lung environment, is gaining a strong interest to examine health risks associated to PM exposure. In this study, OP was measured by two different acellular assays (dithiothreitol, DTT and ascorbic acid, AA) on PM10 filter samples from 15 yearly time series of filters collected at 14 different locations in France between 2013 and 2018, including urban, traffic and Alpine valley site typologies. A detailed chemical speciation was also performed on the same samples allowing the source-apportionment of PM using positive matrix factorization (PMF) for each series, for a total number of more than 1700 samples. This study provides then a large-scale synthesis on the source-apportionment of OP using coupled PMF and multiple linear regression (MLR) models. The primary road traffic, biomass burning, dust, MSA-rich, and primary biogenic sources had distinct positive redox-activity towards the OPDTT assay, whereas biomass burning and road traffic sources only display significant activity for the OPAA assay. The daily median source contribution to the total OPDTT highlighted the dominant influence of the primary road traffic source. Both the biomass burning and the road traffic sources contributed evenly to the observed OPAA. Therefore, it appears clearly that residential wood burning and road traffic are the two main target sources to prioritized in order to decrease significantly the OP in Western Europe and, would the OP being a good proxy of human health impact, to lower the health risks from PM exposure.
Observational evidence of energetic particle precipitation NOx (EPP-NOx) interaction with chlorine curbing Antarctic ozone loss

Published: February 2021

Abstract. We investigate the impact of the so-called energetic particle precipitation (EPP) indirect effect on lower stratospheric ozone, ClO, and ClONO2 in the Antarctic springtime. We use observations from the Microwave Limb Sounder (MLS) and Ozone Monitoring Instrument (OMI) on Aura, the Atmospheric Chemistry Experiment – Fourier Transform Spectrometer (ACE-FTS) on SCISAT, and the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) on Envisat, covering the period from 2005 to 2017. Using the geomagnetic activity index Ap as a proxy for EPP, we find consistent ozone increases with elevated EPP during years with an easterly phase of the quasi-biennial oscillation (QBO) in both OMI and MLS observations. While these increases are the opposite of what has previously been reported at higher altitudes, the pattern in the MLS O3 follows the typical descent patterns of EPP-NOx. The ozone enhancements are also present in the OMI total O3 column observations. Analogous to the descent patterns found in O3, we also found consistent decreases in springtime MLS ClO following winters with elevated EPP. To verify if this is due to a previously proposed mechanism involving the conversion of ClO to the reservoir species ClONO2 in reaction with NO2, we used ClONO2 observations from ACE-FTS and MIPAS. As ClO and NO2 are both catalysts in ozone destruction, the conversion to ClONO2 would result in an ozone increase. We find a positive correlation between EPP and ClONO2 in the upper stratosphere in the early spring and in the lower stratosphere in late spring, providing the first observational evidence supporting the previously proposed mechanism relating to EPP-NOx modulating Clx-driven ozone loss. Our findings suggest that EPP has played an important role in modulating ozone depletion in the last 15 years. As chlorine loading in the polar stratosphere continues to decrease in the future, this buffering mechanism will become less effective, and catalytic ozone destruction by EPP-NOx will likely become a major contributor to Antarctic ozone loss.
Defluoridation of drinking water by modified natural zeolite with Cationic surfactant, in case of Ziway town, Ethiopia
Authors: Geleta Ebsa Dessalegn , Kebede Adisu Befekadu
Published: February 2021

Abstract. In Ethiopia (Ziway town) an excess fluoride (≥ 1.5 mg/L) consumption in drinking water (ground water and Lake Ziway) sources causes a health problem on the communities. The surrounding of inhabitant's peasant farmers of drinking water sources was extremely relying on this polluted fluoride concentration of water. This investigation was focused on defluoridation of drinking water by natural zeolite modified with a cationic surfactant in a batch system and Hexadecy Trimethyl Ammonium Bromide were used for zeolite modification. The Batch experiments also conducted to test for preferential removal of fluoride from water by surfactant-modified zeolite. The zeolite treatments had an aggregate size of 1.4 to 2.4 mm. The cationic surfactant-modified zeolite, and raw zeolite were used in all experiments. The removal efficiency of the treatment was influence by pH of solution (5.5 ± 0.2–8.5 ± 0.2), initial concentration of fluoride (1–10 mg/L), dose of surfactant-modified zeolite (2.5–18 g/L), contact time (30–180 Minute), and effect of temperature was investigated. The study investigated that, at the constant Blank of 10 mg/L, 5 g/L of Hexadecy Trimethyl Ammonium Bromide dosage noted the highest fluoride removal potential at the end of the 3hours runtime: Na-LSX (88.4 %), Na-LTA (64.6 %) and ZR (79.8 %). Incompatible to this reflection, the model waters with pH maintained at 5.5 ± 0.2 and 6.5 ± 0.2 verified rapid fluoride removal (89.7 % and 72.3 % respectively) within the first 60 minutes of runtime.
Multilayer-HySEA model validation for landslide-generated tsunamis – Part 2: Granular slides
Authors: Macías Jorge , Escalante Cipriano , Castro Manuel J.
Published: February 2021

Abstract. The final aim of the present work is to propose a NTHMP-benchmarked numerical tool for landslide-generated tsunami hazard assessment. To achieve this, the novel Multilayer-HySEA model is validated using laboratory experiment data for landslide-generated tsunamis. In particular, this second part of the work deals with granular slides, while the first part, in a companion paper, considers rigid slides. The experimental data used have been proposed by the US National Tsunami Hazard and Mitigation Program (NTHMP) and were established for the NTHMP Landslide Benchmark Workshop, held in January 2017 at Galveston (Texas). Three of the seven benchmark problems proposed in that workshop dealt with tsunamis
generated by rigid slides and are collected in the companion paper
(Macías et al., 2021). Another three benchmarks considered tsunamis generated by granular slides. They are the subject of the present study. The seventh benchmark problem proposed the field case of Port Valdez, Alaska, 1964 and can be found in Macías et al. (2017). In order to reproduce the laboratory experiments dealing with granular slides, two models need to be coupled: one for the granular slide and a second one for the water dynamics. The coupled model used consists of a new and efficient hybrid finite-volume–finite-difference implementation on GPU architectures of a
non-hydrostatic multilayer model coupled with a Savage–Hutter model. To introduce the multilayer model more fluidly, we first present the equations of the one-layer model, Landslide-HySEA, with both strong and weak couplings between the fluid layer and the granular slide. Then, a brief description of the multilayer model equations and the numerical
scheme used is included. The dispersive properties of the multilayer model can be found in the companion paper. Then, results for the three NTHMP benchmark problems dealing with tsunamis generated by granular slides are presented with a description of each benchmark problem.
The GRISLI-LSCE contribution to the Ice Sheet Model Intercomparison Project for phase 6 of the Coupled Model Intercomparison Project (ISMIP6) – Part 1: Projections of the Greenland ice sheet evolution by the end of the 21st century
Authors: Quiquet Aurélien , Dumas Christophe
Published: February 2021

Abstract. Polar amplification will result in amplified temperature changes in the Arctic with respect to the rest of the globe, making the Greenland ice sheet particularly vulnerable to global warming. While the ice sheet has been showing an increased mass loss in the past decades, its contribution to global sea level rise in the future is of primary importance since it is at present the largest single-source contribution after the thermosteric contribution. The question of the fate of the Greenland and Antarctic ice sheets for the next century has recently gathered various ice sheet models in a common framework within the Ice Sheet Model Intercomparison Project for the Coupled Model Intercomparison Project – phase 6 (ISMIP6). While in a companion paper we present the GRISLI-LSCE (Grenoble Ice Sheet and Land Ice model of the Laboratoire des Sciences du Climat et de l'Environnement) contribution to ISMIP6-Antarctica, we present here the GRISLI-LSCE contribution to ISMIP6-Greenland. We show an important spread in the simulated Greenland ice loss in the future depending on the climate forcing used. The contribution of the ice sheet to global sea level rise in 2100 can thus be from as low as 20 mm sea level equivalent (SLE) to as high as 160 mm SLE. Amongst the models tested in ISMIP6, the Coupled Model Intercomparison Project – phase 6 (CMIP6) models produce larger ice sheet retreat than their CMIP5 counterparts. Low-emission scenarios in the future drastically reduce the ice mass loss. The oceanic forcing contributes to about 10 mm SLE in 2100 in our simulations. In addition, the dynamical contribution to ice thickness change is small compared to the impact of surface mass balance. This suggests that mass loss is mostly driven by atmospheric warming and associated ablation at the ice sheet margin. With additional sensitivity experiments we also show that the spread in mass loss is only weakly affected by the choice of the ice sheet model mechanical parameters.
Wind tunnel comparison of four VAWT configurations to test load-limiting concept and CFD validation
Authors: Wiśniewski Jan , Rogowski Krzysztof , Gumowski Konrad , Szumbarski Jacek
Published: February 2021

Abstract. The article describes results of experimental wind tunnel
testing of four different straight-bladed vertical axis wind turbine model
configurations. The experiment tested a novel concept of vertically dividing
and azimuthally shifting a turbine rotor into two parts with a specific
uneven height division in order to limit cycle amplitudes and average cycle
values of bending moments at the bottom of the turbine shaft to increase
product lifetime, especially for industrial-scale turbines. Testing
reduction effects of simultaneously including a vertical gap between turbine
rotor levels, increasing shaft length but also reducing aerodynamic
interaction between rotor levels, has also been performed. Experiment
results have shown very significant decreases of bending moment cycle
amplitudes and average cycle values, for a wide range of measured wind
speeds, for dual-level turbine configurations as compared to a single-level
turbine configuration. The vertical spacing between levels equal to a
blade's single chord length has proven to be sufficient, on
laboratory scale, to limit interaction between turbine levels in order to
achieve optimal reductions of tested parameters through an operating cycle
shift between two position-locked rotor levels during a turbine's expected
lifetime. CFD validation of maintaining the effect on industrial scale has
been conducted, confirming the initial conclusions.

Authors: Hukom Kenia , Madrigal Dennis
Published: February 2021

Academic stress is a certain level of academic-related demands that exceed the students' adaptive capabilities. Related to this is coping strategies, which is a mindful effort to endure the stress. Thus, the descriptive-correlational research determined the associations among the demographic variables, the level of academic stress, and the extent of coping strategies. Academic Stress Scale and COPE Inventory standardized tests, were used among sixty-seven Filipino high school students with single-parents of a Catholic school. The data were statistically analyzed using Mean, Standard Deviation, Pearson r, and Spearman rank correlation. As a whole, their academic stress is low with no significant relationship between academic level and single-parents' educational level.  However, a moderate level of academic stress was found with a significant relationship between sex and family monthly income. The overall coping strategies is great with a significant relationship between family monthly income. However, there is no significant relationship between coping strategies and academic level, sex, and single-parents' educational level. Finally, no significant relationship was found between academic stress and coping strategies. The study recommends designing an enhanced stress management program for high school students.

PENGARUH PEMBELAJARAN BERBASIS EDMODO TERHADAP MOTIVASI BELAJAR MAHASISWA PGSD STKIP MUHAMMADIYAH MUARA BUNGO
Authors: Yulianti Andam , Hidayat Puput Wahyu
Published: February 2021

The background in this study is the learning motivation of STKIP Muhammadiyah Muara Bungo students is still low in Indonesian subjects. One reason is the learning approach that is not right. Although the implementation has implemented learning by leading students to be more active in learning, but there are still weaknesses in learning, which causes low motivation to learn. This can be seen when doing learning activities, students prefer to chat with their friends when friends in the group in front are explaining the material. Another thing that happens is, when students do not master the group material, the audience becomes noisy, so that learning time is wasted. So, with existing problems, an effort can be made to improve learning activities. One effort that can be done is by applying edmodo-based learning. The purpose of this study was to determine the effect of Edmodo-based e-learning learning approaches on the learning motivation of STKIP Muhammadiyah Students in Muara Bungo. This type of research is a quasi-experimental study with pretest-posttest nonequivalent group design. This research has been carried out in STKIP Muhammadiyah Muara Bungo PGSD Study Program in 2020. The instrument used to measure learning motivation was 30 statements. Data were analyzed using descriptive analysis test and inferential analysis test which included tests of normality, homogeneity and hypothesis testing. The results showed that there was a significant influence with edmodo-based e-learning learning on student motivation.

Spontaneous pneumomediastinum (SPM) is an uncommon and usually benign self-limiting clinical disorder found in young people, often without apparent precipitating factors or diseases. A pressure gradient exists between the peripheral pulmonary alveoli and the hilum, and increased intra-alveolar pressure causes rupture of the terminal alveoli. We present the case of a 15-year-old male soccer player who presented with a complaint of anterior chest pain and dysphagia after stopping the strong ball with his chest. His symptom gradually progressed over hours. We can make the diagnosis of SPM using by chest X-ray and computed tomography (CT) scanning. His symptoms were gradually resolved over the course of approximately one week with no exercise and careful observation. We believe that our case provides very useful information to alert clinicians and coaches regarding this rare disease that may occur in anyone including adolescent soccer players.
Costa Rica: dos pandemias en un siglo
Authors: Vega Jiménez Patricia
Published: February 2021

Este texto tiene como objetivo comparar dos pandemias vividas en Costa Rica en el último siglo: la denominada “gripe española” en 1920 y la del COVID 19 en 2020. A través de un seguimiento a lo poco que se ha escrito sobre la enfermedad de 1920 y la cuantiosa información emanada de la que se padece en 2020, se extraen las diferencias y similitudes en las manifestaciones del mal, se indagan las medidas tomadas por los gobiernos y los resultados obtenidos. Ambas muestran una similitud categórica en todos los campos, incluso en el comportamiento de las personas, pero las diferencias también son evidentes: es otra coyuntura con conocimientos más avanzados pero formando parte de un mundo globalizado que hace más difícil el control del virus. Como consecuencia de las pandemias, murieron miles de personas y en los dos casos se acentuó la crisis económica con las consecuencias socio políticas derivadas.

Os resultados apontam que os cursos de Licenciatura ofertam a disciplina de Libras como obrigatória e com carga horária ampliada em relação aos cursos de bacharelado, que ofertam a disciplina de forma eletiva e com carga horária menor. Apontam, ainda, que não há variação significativa de conteúdos das ementas entre os cursos de licenciatura e bacharelado, desconsiderando-se as especificidades de cada um deles.

Écfrasis: La estética pictórica en la obra rubendariana
Authors: Cruz Arce Celia Isabel , Castillo Alfaro Kelly Andrea
Published: February 2021

El propósito del presente ensayo ha sido fundamentar, a base de un análisis, la relación existente entre la poesía de Rubén Darío y la pintura. Se partió desde el precepto “ut pictura poesis” de Horacio y del concepto de la écfrasis, que, desde los tiempos de los clásicos grecolatinos, han guiado el estudio sobre la naturaleza y correspondencia de las denominadas artes hermanas: La poesía y la pintura. Para trabajar dicha tesis se hizo una selección de obras de carácter ecfrástico, tanto poemas como cuentos, con la intención de identificar los principales símbolos literarios y poéticos que remiten a la pintura, y así fuera posible confirmar y analizar la riqueza de la Obra Rubendariana en cuanto a los rasgos pictóricos que la residen.

Condições de trabalho e os impactos na saúde dos motoristas de transporte de lotação
Authors: Pereira Izete Soares da Silva Dantas , Araujo Ana Jéssica Nunes
Published: February 2021

O trabalho realizado pelos motoristas de transporte de lotação se caracteriza por condições precárias com repercussões à saúde. A jornada de trabalho com consequente sobrecarga física e psicológica provoca o aparecimento de sintomas e sinais físicos e mentais, doenças crônicas e agudas. O objetivo geral da pesquisa foi conhecer as Condições de trabalho e os impactos na saúde dos motoristas de transporte de lotação. Tratou-se de estudo transversal descritivo e exploratório com abordagem qualitativa a partir da realização de entrevistas semiestruturadas com 34 profissionais associados de uma Cooperativa de Transportes de Lotação no Rio Grande do Norte. Os resultados mostraram que as condições de trabalho dos motoristas se caracterizam por excesso de horas, doenças cardiovasculares, psicofisiológicas, ausência de cuidados preventivos, além de outros problemas que impactam na saúde. Há necessidade de maior investimento em ações de prevenção e promoção da melhoria da saúde desses profissionais a fim de que sejam asseguradas melhores condições de trabalho minimizando os fatores de risco a que estão expostos.
Mediação da informação e a proteção da privacidade e de dados sensíveis por bibliotecários
Authors: Vignoli Richele Grenge , Veronez Júnior Wilson Roberto , Silva Anahi Rocha , Monteiro Silvana Drumond
Published: February 2021

Introdução: Destaca o papel do bibliotecário no resguardo e sigilo de informações que não podem, não devem ou que não necessitam ser mediadas. Para isso, contextualiza a mediação da informação e apresenta ambiências legais, balizadas na Constituição Federal do Brasil, da Lei de Acesso à Informação, da Lei de Proteção de Dados Pessoais, e ambiências éticas com fulcro no Código de Ética e Deontologia do Bibliotecário no Brasil e no Código de Ética da American Library Association, na precisão e observância de condutas necessárias para não mediar dados ou informações sigilosas e sensíveis de usuários. Objetivo: O objetivo da pesquisa é discutir a respeito dos dados sensíveis na mediação da informação, seja de forma implícita (no processamento técnico da informação) ou na explícita (no atendimento direto a usuários), e no acesso a dados sensíveis de usuários em unidades de informação. Metodologia: Como procedimento metodológico, trata-se de uma pesquisa bibliográfica com abordagem qualitativa. Resultados: Constata-se que dados sensíveis não devem ser divulgados e que por isso, nem toda informação é passível de compartilhamento e mediação. Conclusões: Espera-se contribuir com novas pesquisas e discussões acerca da temática e principalmente com outros estudos nos construtos da literatura da mediação da informação aliada aos dados sensíveis.
Processos de Gestão do Conhecimento fomentados pelos portais dos tribunais das 27 UFs do Brasil
Authors: Santos Paloma Maria , Rover Aires José
Published: February 2021

Introdução: No setor público, a implementação da gestão do conhecimento apresenta um importante papel no aumento da transparência, na melhoria da governança e da relação entre o governo e os cidadãos. Ela dá suporte à criação e ao compartilhamento de conhecimento e contribui para que o cidadão participe efetivamente na elaboração de políticas e no processo de tomada de decisão. Objetivo: Com o intuito de analisar em que medida o Poder Judiciário está empreendendo ações que condicionem o cidadão a assumir um papel mais ativo na condução do bem público, o presente artigo buscou traçar um panorama nacional dos processos de gestão do conhecimento fomentados pelos portais dos tribunais das 27 Unidades Federativas do Brasil. Metodologia: Como suporte à análise, utilizou-se um instrumento de pesquisa que permite investigar a ocorrência de variáveis que apresentam vínculo com as práticas e os processos de gestão do conhecimento encontrados na literatura. Resultados: Os resultados encontrados permitem inferir que apesar de algumas das iniciativas disponíveis se mostrarem facilitadoras da comunicação entre o governo e o cidadão, raras foram as que efetivamente permitiam a criação e o compartilhamento do conhecimento. Entende-se, desse modo, que os portais dos tribunais de justiça estão longe do cenário ideal e precisam urgentemente melhorar sua qualidade para que possam, de fato, promover a democratização do acesso à justiça.

Published: February 2021

O artigo objetiva iniciar discussões sobre o tema do empreendedorismo informacional como um novo processo da Ciência da Informação. Tal objetivo está relacionado aos seguintes questionamentos: o que é empreendedorismo informacional? O empreendedorismo informacional pode contribuir para o processo da gestão da informação? A metodologia é de natureza qualiquantitativa, do tipo descritivo-exploratória, que utiliza as técnicas de análise bibliográfica e de análise cientométrica para demonstrar como o empreendedorismo informacional é abordado pela Ciência da Informação, bem como sua relação com a gestão da informação. Os resultados demonstraram que os estudos ainda são escassos na área e, portanto, existem oportunidades de pesquisa sobre a temática. Além disso, demonstrou-se a inter-relação entre o empreendedorismo informacional com a gestão da informação e o quanto essa conexão contribui para que as organizações se tornem mais competitivas e obtenham melhores resultados. As considerações finais apontam que o empreendedorismo informacional está relacionado com a criação de novos negócios e procedimentos no processo produtivo e se serviço, mediante o uso da informação para a construção de conhecimento e geração de lucros.
Revolution of Nursing Science in the Next Decade
Authors: Tulyakul Phatcharapon , Meepring Soontareeporn
Published: February 2021

Knowing a history of nursing science allows nurses to understand the journey of nursing theorists and scientists in developing the nursing science. Since the era of Florence Nightingale in the mid-18th century, the nursing theories and nursing research were published to the public, particularly scientific community. During late 18th and 19th century, there were many interesting questions among these debates that have not been answer yet, such as is it a nursing science or science of nursing? and is it a pure science or applied science? Even though the scientific community acknowledges that nursing is known as a science, many scholars remain to discuss the definition and category of nursing science.

Along the history of nursing knowledge development, nursing scholars faced many challenges concerning the difficulty to develop the required content for nursing practices, to be an excellent discipline in the developing science base, to prepare nurse researchers, and to disseminate research results to the community and to the public (Hinshaw, 1989). Nowadays nursing science is entering into the postmodern era and it will be continued development in the next decade. Even if nurses do not recognise that nursing knowledge is currently in crisis, looking for the future of nursing science throughout the principle of Kuhn’s paradigm shift might provide valuable direction for nurse. Therefore, this paper aims to explain Kuhn’s revolutionary theory and its principle. Moreover, the influence of Kuhn’s revolution theory on the revolution of nursing science that will be present in this paper.
Saudi Pre-Service Special Education Teachers’ Knowledge and Perceptions Toward Using Computer Technology
Authors: Alanazy Manal M. , Alrusaiyes Reem F.
Published: February 2021

The authors investigated pre-service special education teachers’ prior experience in using computers and their perception of the knowledge, and their preparedness toward integrating computer technology in teaching, barriers in integrating computer technology in their teaching practices and the level of confidence teachers gained from using technology applications in teaching. Fifty-eight pre-service special education female teachers from a college of education in Saudi Arabia responded to a needs assessment survey. Most participants had more than eight years of experience in using computers. They reported that they are able to integrate computer technologies in their teaching but acknowledged the need for more training courses. The barriers mentioned were a lack of equipment, lack of practice, and lack of maintenance. The findings of this research reveal that there is a need to intensify or enhance the technology courses in programs that prepare special education teachers and focus on the practical aspects of integrating technology in teaching.
Non-English Majors’ Writing Self-Efficacy and Attribution in Learning English as a Foreign Language
Authors: Chen Zenan
Published: February 2021

This study examines the relationship between writing self-efficacy, attribution, and writing proficiency of college students in learning English as a foreign language (EFL) context. The scales of writing self-efficacy and attribution were administered to 142 Chinese first-grade non-English majors. Research findings showed that these EFL learners maintained a medium level of writing self-efficacy and tended to attribute their writing outcomes to internal causes. Independent sample t-test indicated that gender exerted no significant influence on EFL writing self-efficacy, and only the attribution cause luck significantly differed between boys and girls. Besides, high-achievers reported stronger writing self-efficacy and skill self-efficacy, while no significant difference in task self-efficacy was found between high-achievers and low-achievers. One-way ANOVA results revealed that regardless of writing level, students tended to attribute their writing success or failure to internal factors such as ability and effort, while low-achievers were also inclined to attribute externally. Pedagogical implications were also discussed.
