ABSTRACT Objective: To compare the nursing workload in an oncology intensive care unit according to the condition of COVID-19 infection. Method: A retrospective cohort study. The Nursing Activities Score was used to measure the workload and document analysis for data extraction. The medical records were divided into a group of patients with COVID-19 and another group of patients without the infection. Results: The values of the Nursing Activities Score were not different depending on the sociodemographic variables, but the average of this score was statistically different depending on whether the patient had the diagnosis of COVID-19 or not, being higher in those who had the disease. Conclusion: It was proved that the nursing workload is high in the context of the oncology intensive care unit. However, COVID-19 increased this score even more, with the Nursing Activities Score being an important tool to size the team in this context.

Por lo tanto, los objetivos del estudio fueron analizar la asociación entre la calidad de la relación en trenador-atleta (CAR) y la percepción de la cohesión del equipo de los atletas jóvenes. Participaron 301 atletas, de 15 a 17 años, que compitieron en los Juegos Escolares de Pernambuco, Brasil. Los instrumentos utilizados fueron el Cuestionario de Relación Entrenador-Atleta (CART-Q) y el Cuestionario de Ambiente Grupal (GEQ). El análisis de los datos se realizó a través del modelado de ecuaciones estructurales (p <.05). Los resultados mostraron que la calidad de la CAR mostró una asociación significativa (p <.05) con la cohesión del equipo, explicando el 25% de la varianza de la cohesión de la tarea y el 15% de la cohesión social. Específicamente, el efecto de CAR en la cohesión de tareas (β = 0.50) y social (β = 0.39) fue significativo (p <.05) y positivo. Se concluyó que la calidad de CAR es un factor clave para el compromiso del adolescente con el trabajo en equipo y las metas de este, así como para el desarrollo de relaciones interpersonales positivas.

Abstract The relationship between coach and athlete has been identified as a key factor for several positive outcomes in the sports context. Thus, the aims of this study were to analyze the association between the quality of the coach-athlete relation ship (CAR) and the perception of team cohesion of youth athletes. Participants were 301 athletes, aged 15 to 17 years, who participated in the School Games of Pernambuco, Brazil. The instruments used were the Coach-Athlete Relationship Questionnaire (CART-Q) and the Group Environment Questionnaire (GEQ). Data analysis was conducted through the Structural Equation Modeling (p< .05). The results showed that the quality of CAR showed a significant association (p<.05) with team cohesion, explaining 25% of the variance of task cohesion and 15% of social cohesion. Specifically, the effect of CAR on task (β = 0.50) and social (β = 0.39) cohesion was significant (p<.05) and positive. It was concluded that the quality of CAR is a key factor for the engagement of the adolescent with the teamwork and its goals as well as for the de velopment of positive interpersonal relationships.

Abstract Vertebrates, overall, present a daily activity pattern when managing their needs, such as foraging, resting or searching for sexual partners. Most of the available information regarding the circadian rhythm in birds comes from controlled laboratory conditions, and little is known about these patterns in the wild. In this study we used camera traps to describe the daily activity patterns of three cracid species in the Pantanal of Rio Negro, Brazil. We had a sampling effort of 9,617 camera trap-days along 231 days (5,544 hours) from September 2013 to May 2014. This resulted in 4,833 independent records of cracids from a total of 7,713 individuals. Crax fasciolata was the species with the most records (nrec = 3,792) and individuals (nind = 5,781), followed by Ortalis canicollis (nrec = 934; nind = 1,758) and Aburria grayi (nrec = 107; nind = 174). None of the species was uniformly distributed throughout the day, thus evidencing a periodization of their activities. The mean vectors of the activity patterns of C. fasciolata, O. canicollis and A. grayi were, respectively, mμ = 10:36 ± 04:26 (SD), mμ = 11:42 ± 03:57 and mμ = 11:44 ± 03:47. We observed a temporal overlap between A. grayi and O. canicollis, whereas C. fasciolata significantly differed from them. Because of their large home ranges, cracids are important indicators of environmental quality, and, as frugivores, they play key roles in the ecological dynamics of forests. In this sense, and given that cracids are notably more susceptible to extinction, the knowledge on their circadian activity patterns may be useful when establishing effective management and conservation strategies.

Abstract Cenostigma pyramidale is a native legume of the Brazilian semiarid region which performs symbiotic association with arbuscular mycorrhizal fungi (AMF), being an excellent model for studying genes associated with tolerance against abiotic and biotic stresses. In RT-qPCR approach, the use of reference genes is mandatory to avoid incorrect interpretation of the relative expression. This study evaluated the stability of ten candidate reference genes (CRGs) from C. pyramidale root tissues under salt stress (three collection times) and associated with AMF (three different times of salinity). The de novo transcriptome was obtained via RNA-Seq sequencing. Three algorithms were used to calculate the stability of CRGs under different conditions: (i) global (Salt, Salt+AMF, AMF and Control, and collection times), (ii) only non-inoculated plants, and (iii) AMF (only inoculated plants). HAG2, SAC1, aRP3 were the most stable CRGs for global and AMF assays, whereas HAG2, SAC1, RHS1 were the best for salt stress assay. This CRGs were used to validate the relative expression of two up-regulated transcripts in Salt2h (RAP2-3 and PIN8). Our study provides the first set of reference genes for C. pyramidale under salinity and AMF, supporting future researches on gene expression with this species.

In this work, the gas diffusion electrode (GDE) cathode of Vulcan XC72 carbon modified with nanoparticles of WO2.72 (WO2.72 / Vulcan XC72) was used for H2O2 electrogeneration and degradation of 350 mL of Orange II (OII) and Sunset Yellow FCF (SY) azo dyes by electro-Fenton (EF) and photoelectro-Fenton (PEF) processes with different Fe2+ initial content (1.00, 0.50 and 0.25 mmol L-1). The WO2.72 / Vulcan XC72 GDE electrolyzed approximately 3 times more H2O2 than the Vulcan XC72 GDE. Decolorizations and mineralizations of the dye solutions were more efficient at higher concentrations of Fe2+. The decolorization decay showed pseudo-first-order kinetics. The most promising decolorization results obtained at processes of WO2.72 / Vulcan XC72 cathode combined with Pt anode (100% color removal of OII and SY at 30 and 20 min of electrolysis with 1.00 mmol L-1 Fe2+, respectively). The best mineralization achieved in trials of WO2.72 / Vulcan XC72 cathode combined with boron-doped diamond (BDD) anode (82% total organic carbon (TOC) removal of OII by PEF / 1.00 after 3 h and 90% TOC removal of SY by PEF / 0.50 after 4 h). It was found that SY decolorization was faster and mineralization showed a similar yield independent of oxidized dye.

This work describes the preparation of Pt/C, PtxSny/C and PtxSny(CeO2 nanorods/C) nanoparticle catalysts synthesized by the chemical reduction method via sodium borohydride for the ethanol oxidation reaction. Using X-ray diffractogram analysis, it was verified that no alloy formation occurred between platinum (Pt) and tin (Sn). The distribution of the nanoparticles in the support occurs in a more agglomerated form for the materials containing Sn and CeO2 nanorods (NR). The electrocatalyst Pt3Sn1_20%NRCeO2/C was highlighted in CO-stripping experiments because it showed the lowest onset potential for CO oxidation and the highest value for the electrochemically active surface area. The other electrochemical experiments for ethanol oxidation showed similar activities for the Pt3Sn1/C and Pt3Sn1_20%NRCeO2/C electrocatalysts. The observed effect can be associated with defects in the structure of the CeO2 nanorods, the electrochemical active surface area, and the properties of the CeO2 nanorods related to enhancing the generation of oxy-hydroxy species at lower potentials compared to PtSn/C electrocatalysts, which increased the CO oxidation as measured using stripping experiments. For this reason, it is possible to both use less platinum and to obtain behavior close to that of PtSn/C electrocatalysts for ethanol oxidation reaction (EOR).

RESUMO Na Bacia Hidrográfica do Rio Doce, no Sudeste brasileiro, município de Mariana (MG), o rompimento da barragem de Fundão, em 5 de novembro de 2015, desencadeou o desastre da Samarco/Vale/BHP. O desastre não foi uma ocorrência natural, pois resultou da adoção de tecnologias e decisões técnico-administrativas, cujas responsabilidades criminais foram apontadas pelo Ministério Público. Os impactos foram diretos e indiretos sobre rios e terrenos aluviais; sobre as áreas de proteção ambiental, reservas florestais, flora e fauna; sobre os habitats, hábitos e os coabitantes rurais e urbanos; e sobre a zona costeira no estado do Espírito Santo. O artigo busca identificar a problemática que emerge do desastre, discutir as consequências do sentimento de incerteza e analisar a pertinência do desastre como objeto de investigação, sem desconsiderar o papel da mídia na sua construção como evento.

ABSTRACT In the Brazilian Southeast, in the basin of the Doce River, the municipality of Mariana (MG), the rupture of the Fundão mineral tailings dam on November 5, 2015, triggered the so-called Samarco/Vale/BHP disaster. This was not a natural event but the outcome of adopting particular technologies and technical-administrative decisions. Criminal responsibilities for the disaster were identified by the Public Prosecutor’s Office. There were both direct and indirect impacts on rivers and alluvial lowlands, environmental protection areas, forest reserves, flora and fauna. The incident affected rural and urban habitats, habits and cohabitants. Its harmful effects reached the Atlantic coastal region of Espírito Santo state. This article aims to identify the problems that emerged from the disaster, discuss the consequences of the feelings of uncertainty, and analyse the pertinence of the disaster as a research issue, while also paying attention to the media’s role in its social construction as an event.

ABSTRACT Studies addressing the physiological and anatomical responses of plants under different light intensities normally are performed in short term. Thus, the present study includes a long term analysis. This study aims to verify whether the phenotypic variability off attributes in two woody tropical specieis, Paquira aquatica and Sterculia foetida, are compatible both under short term exposure to different light availability levels (full-light and half-light local irradiance) and long-term exposure in the same conditions. The study was developed in two phases: phase I (short term) and phase II (long term). The variables measured were referent to CO2 assimilation responses to light intensity, chlorophyll a fluorescence, chlorophyll content, morpho-anatomical attributes and phenotypic variability. In phase I, P. aquatica had differences between treatments in Amax (maximum net photosynthesis) and LCP (light compensation point), without differences in these attributes in phase II. S. foetida plants had differences only in phase I in Amax. In anatomical attributes, P. aquatica had a higher palisade and spongy parenchyma and mesophyll thickness compared to S. foetida plants, without differences between light treatments. In S. foetida, the aforementioned cell layers were thicker in full-light treatment. Both species showed a higher phenotypic variability in the same physiological attributes in phase I and similar attributes for mesophyll thickness of the abaxial epidermis in phase II. The species showed different anatomical and physiological strategies, however with plastic responses in similar attributes, only observable after a longer period of exposure. The results indicated the importance of lengthy exposure to light, mainly in tropical species, wich are naturally exposed to elevated irradiance levels for an extended period of time in the field.
