Resumen Se estudió la redistribución de la precipitación en dos especies del género Pinus en el ejido Adolfo Ruiz Cortines, Pueblo Nuevo, Durango, con el objetivo de evaluar la precipitación incidente, precipitación directa, escurrimiento fustal, pérdidas por intercepción, valores de pH y conductividad eléctrica para las especies Pinus teocote y Pinus engelmannii. Se evaluaron 26 eventos de lluvia, en una parcela de 2 500 m2, donde se midieron las propiedades hidrológicas durante el periodo de junio a diciembre de 2019. Los resultados indicaron una precipitación incidente de 812.28 mm. La precipitación directa en P. engelmannii y en P. teocote representó 84.93 y 83.15 %, respectivamente, con un promedio de 84 % de la precipitación total. El escurrimiento fustal representó 0.29 % para P. engelmannii y 0.33 % en P. teocote; mientras que las pérdidas por intercepción del dosel vegetal fueron de 16.52 % para P. teocote y 15 % para P. engelmannii. En el pH del pluviolavado, el valor más alto respecto a la precipitación incidente fue 7.0, para el escurrimiento fustal de P. teocote de 4.7 y para P. engelmannii de 5.5; la precipitación directa registró un pH de 5.4 para las dos especies. La conductividad eléctrica mostró una tendencia de aumento conforme recorría las copas y fustes de los árboles; se obtuvo un valor de 29.5 μS cm-1 en la precipitación incidente, 44.4 μS cm-1 en la precipitación directa y el escurrimiento fustal registró valores superiores, con un promedio de 90.2 μS cm-1.

Abstract The redistribution of rainfall was studied in two species of the Pinus genus in the Adolfo Ruiz Cortines ejido, Pueblo Nuevo, state of Durango, with the aim of evaluating incident rainfall, direct rainfall, stemflow, interception losses, pH values, and electrical conductivity for Pinus teocote and Pinus engelmannii. Twenty-six rainfall events were assessed in a 2 500 m2 plot, where hydrological properties were measured from June to December 2019. Results indicated an incident rainfall of 812.28 mm. Direct rainfall in P. engelmannii and P. teocote amounted to 84.93 and 83.15 %, respectively, with an average of 84 % of total rainfall. Stemflow amounted to 0.29 % for P. engelmannii and 0.33 % for P. teocote. Meanwhile, canopy interception losses were 16.52 % for P. teocote and 15 % for P. engelmannii. In the rainfall pH, the highest value compared to the incident rainfall was 7.0, for the stemflow of P. teocote it was 4.7 and for P. engelmannii it was 5.5; direct rainfall recorded 5.4 pH for both species. The electrical conductivity exhibited an increasing trend as it traveled through the tree crowns and stems; a value of 29.5 μS cm-1 was obtained for the incident rainfall, 44.4 μS cm-1 for the direct rainfall, and the stemflow registered higher values, with an average of 90.2 μS cm-1.

RESUMO Objetivo: Investigar a associação entre a anemia por deficiência de ferro e a duração do sono no primeiro ano de vida. Métodos: Foram avaliadas 123 crianças, sendo o sono investigado aos três, seis e 12 meses de idade e a anemia ao nascimento e aos seis meses. Utilizaram-se como pontos de corte para anemia e curta duração de sono, respectivamente, hemoglobina<11 g/dL (nascimento e/ou seis meses) e tempo total <10 h (3, 6 e/ou 12 meses). A comparação do tempo médio de sono entre as crianças com e sem anemia foi realizada pelo teste t de Student e modelos de regressão logística foram usados para verificar diferenças na duração do sono (curta/não curta) entre os grupos. Análises de regressão linear foram conduzidas para determinar a associação entre a duração do sono e valores de hemoglobina. As análises foram ajustadas para potenciais confundidores. Resultados: As crianças com anemia tiveram maior chance de apresentar curta duração do sono [odds ratio — OR (intervalo de confiança — IC95%): 4,02 (1,02–15,76); p≤0,05]. Para cada unidade de aumento nos valores da hemoglobina, o tempo de sono aumentou em 16,2 min [β (IC95%): 0,27 (0,00–0,55); p≤0,05), independentemente de renda familiar, escolaridade materna, sexo e índice de massa corporal ao nascimento. Conclusões: Nossos resultados sugerem que a anemia ferropriva está associada à curta duração do sono no primeiro ano de vida e indicam a necessidade de investigações longitudinais, com maior tempo de seguimento, para verificar o impacto da anemia na duração do sono em idades subsequentes.

Abstract Objective: The aim of this study was to investigate the association between iron deficiency anemia and sleep duration in the first year of life. Methods: A total of 123 infants were investigated, with sleep being evaluated at 3, 6, and 12 months of age and anemia at birth and 6 months. The cutoff points for anemia and short sleep duration were hemoglobin <11 g/dL (at birth and/or 6 months) and <10 h (at 3, 6, and 12 months), respectively. The comparison of the average sleep time between infants with and without anemia was performed using the Student’s t-test, and logistic regression models were also used to verify differences in the sleep duration (short/not short) between the groups. Linear regression analyses were conducted to determine the association between sleep duration and hemoglobin values. The analyses were adjusted for potential confounders. Results: Children with anemia were more likely to be short sleepers [odds ratio (95% confidence interval (CI)): 4.02 (1.02–15.76); p≤0.05], and for each unit increase in hemoglobin values, the sleep duration increased by 16.2 min [β (95%CI): 0.27 (0.00–0.55); p≤0.05), regardless of family income, maternal schooling, gender, and body mass index at birth. Conclusions: Our results suggest that iron deficiency anemia is associated with short sleep duration in the first year of life and indicate the need for longitudinal investigations, with longer follow-up, to verify the impact of anemia on sleep duration at subsequent ages.

Abstract Waterborne polyurethane (WPU) coatings used for moisture protection of surfaces have been used broadly. They have been considered environmentally friendly because their synthesis releases less or no volatile organic compounds (VOCs) to the atmosphere. With the Covid-19 pandemic concerns, cleaning protocols of these surfaces have been applied and scientific knowledge about the effects of these liquids on WPU surfaces is necessary. In this work, diffusion experiments were performed using four liquids, in pure WPU and WPU filled with graphene oxide (GO). Detergent had the most severe effect on polyurethane films, causing severe cracks and weight loss. Diffusion parameters of HCl 5% and HCl 10% were greater in WPU/GO nanocomposites than in pure WPU. Mechanical tests under chemical aging showed that alcohol reduced most the tensile strength and Young modulus. Overall, GO protected the films for all liquid exposures, increasing their tensile strength and Young modulus.

ABSTRACT Biological soil crusts (BSC) are commonly found in soils in the drylands regions, which can influence stabilization, water retention, nutrient cycling (particularly carbon (C) and nitrogen (N) dynamics), and several ecological processes. However, the composition of BSC in Brazilian soils undergoing the desertification process remains poorly understood. This study aimed to characterize the bacterial community in BSC formed in a Brazilian semiarid region under the desertification process. Thus, a highly desertified region was selected from which 34 BSC samples were collected. The total DNA of the BSC was extracted from 0.5 g samples, and the bacterial community was sequenced by a Next Generation Sequencing (NGS) platform (Miseq – Illumina®) using universal primers (515F and 806R). Bioinformatic analysis was carried out in QIIME (v.1.9), and the Operational Taxonomic Units (OTU) table was constructed following the Sumaclust methodology. The pH of BSC, C, N, and phosphorus contents was analyzed. Our study identified a diverse bacterial community in the BSCs. Cyanobacteria, Chloroflexi, and Proteobacteria phyla presented the greatest relative abundance (%) across the samples. Cyanobacteria were dominated by the orders Nostocales and Leptolyngbyales. The prediction of the putative functions found that mostf OTU were related to phototrophy, photosynthetic cyanobacteria, and photoautotrophy. The study found correlations between bacterial phyla and BSC properties, with Cyanobacteria positively related to C. Chloroflexi, Armatimonadetes, and WPS-2 were negatively correlated with C and N contents. These results suggest the critical roles bacteria communities play in BSCs from the Caatinga biome and highlight the potential impact of environmental factors on their diversity and functions.

RESUMO O uso de espécies madeireiras tropicais em reflorestamento pode ser uma alternativa para suprir demanda do setor industrial madeireiro, porém o uso ainda é muito limitado, e as florestas tropicais remanescentes ainda seguem sendo deliberadamente exploradas para extração seletiva de espécies nativas de alto valor comercial. Para testar o potencial das espécies tropicais em reflorestamento é necessário avaliar produção e a qualidade da madeira produzida. Sendo assim, este estudo visa avaliar a qualidade da madeira de Astronium urundeuva, Astronium fraxinifolium e Terminalia argentea aos 22 anos oriundas de um plantio heterogêneo, localizado no município de Selvíria-MS. De cada uma das espécies foram selecionadas 15 árvores. De cada árvore foi retirada um disco de 10 cm de espessura da base. Dos discos foram tomadas amostras nas proximidades da região casca para a avaliação das propriedades da madeira. Para isso foram avaliadas as características anatômicas e propriedades físicas e mecânicas das madeiras. De acordo com os resultados verificou-se que somente a resistência à compressão paralela não se diferenciam significativamente entre as espécies. Astronium urundeuva apresentou os maiores valores para densidade básica e densidade aparente e a Terminalia argentea para comprimento se fibra, espessura da parede da fibra e diâmetro de elemento de vaso. As melhores correlações de Pearson foram encontradas para a densidade básica e densidade aparente, tanto para o Astronium fraxinifolium quanto para Astronium urundeuva. As melhores equações de regressões obtidas foram para a relações entre densidade básica e densidade aparente para o Astronium fraxinifolium e Astronium urundeuva, sendo que o modelo linear foi o que melhor ajustou os dados dessas relações. O maier crescimento das árvores de Terminalia argntea ocasionou uma menor densidade da madeira devido a menor taxa de competição entre as árvores. Com base nos resultados e segundo as normas de resistência da madeira, as três espécies podem ser classificadas na classe de resistência D40. Os resultados obtidos podem subsidiar informações que permitam a comparação com espécies utilizadas comercialmente para fins estruturais e outros usos. madeireiro limitado comercial produzida assim 2 heterogêneo SelvíriaMS.

ABSTRACT The use of tropical wood species in reforestation can be an alternative resource to meet the demand from the industrial wood sector. However, this strategy remains very limited, even while tropical forests continue to be deliberately exploited for the selective extraction of native species of highly commercial value. To test the potential of tropical species in reforestation, it is first necessary to evaluate the production and quality of the wood produced. Therefore, this study aimed to evaluate the quality Astronium urundeuva, Astronium fraxinifolium and Terminalia argentea woods, all aged 22 years, from a heterogeneous plantation located in the municipality of Selvíria-MS. From each species, 15 trees were selected. A 10 cm thick disc was removed from the base of each tree. Samples were taken from the discs near the bark region to evaluate the anatomical characteristics and the physical and mechanical properties of the wood. According to the results, it was found that only compressive strength did not differ significantly among the species. Astronium urundeuva presented the highest values for basic density and apparent density, and Terminalia argentea presented the highest values for fiber length, fiber wall thickness and vessel element diameter. The best Pearson correlations were found for basic density and apparent density, both for Astronium fraxinifolium and Astronium urundeuva. The best regression equations obtained were correlations between basic density and apparent density for Astronium fraxinifolium and Astronium urundeuva. The linear model best fits the data for these correlations. The greater growth of Terminalia argentea trees caused lower wood density owing to the lower rate of competition among trees. Based on the results and according to wood strength standards, the three species can be classified in the D40 strength class. According to the obtained results, these can support information to be compared with some species used commercially for structural purposes and other uses. sector However limited value produced Therefore woods 2 years SelvíriaMS.

Abstract: Introduction: Shashi-Pena syndrome is characterized by macrocephaly, intellectual disability and epilepsy, which is confirmed by genetic studies. Case presentation: 15-year-old male patient, with a history of being preterm at 36 weeks of gestation, weight 1,900 grams. From birth he was detected with peripheral hypotonia and swallowing problems. At the age of three he presented status epilepticus. Currently with learning difficulties. Physical examination revealed macrocephaly and facial anomalies. A skull MRI identified septum cavum vergae. IQ was 53 points. In a molecular study, a variant in the ASXL2 gene, c.2843C>T (p.Ala948Val), was reported. Conclusions: variants in the ASXL2 gene are associated with Shashi-Pena syndrome. The diagnosis of this syndrome could result from the detection of patients with macrocephaly associated with other comorbidities.

RESUMEN El presente estudio tiene como objetivos explicitar propuestas epistemológicas y metodológicas realizadas sobre las tecnologías del empoderamiento y la participación (TEP) en educación, así como analizar las propuestas o implementaciones realizadas a nivel praxeológico sobre el uso de las TEP en el ámbito educativo. Se analizaron 19 artículos de Scopus y Web of Science, seleccionados bajo el método Prisma 2009. Los resultados reflejan que la mayoría de los estudios provienen de España, Estados Unidos, Reino Unido e Israel; el nivel educativo más frecuente donde se realizaron los estudios originales fue el pregrado, seguido del posgrado y luego la educación escolar. Las evidencias permiten afirmar que la mayoría de los estudios usan modelos ya existentes para aplicar las TEP como por ejemplo TPACK; la única propuesta para la capacitación docente en el uso de la tecnología fue el Modelo espiral de competencias TIC (tecnologías de la información y la comunicación), TAC (tecnologías del aprendizaje y del conocimiento) y TEP. En cuanto a la aplicación de las TEP se observaron estudios de 4 tipos: 1) basadas en el cotrabajo y el interaprendizaje 2) que promueven la producción de contenidos y/o recursos educativos bajo un enfoque participativo 3) que usan herramientas y/o espacios digitales en la web y 4) que usan Entornos Virtuales de Aprendizaje (EVA).

ABSTRACT The present study aims to make explicit the epistemological and methodological proposals made on the technologies of empowerment and participation (TEP) in education, as well as to analyze the proposals or implementations made at the praxeological level on the use of TEP in the educational field. Nineteen articles from Scopus and Web of Science, selected under the Prisma 2009 method, were analyzed. The results show that most of the studies come from Spain, the United States, the United Kingdom, and Israel; the most frequent educational level where the original studies were carried out was undergraduate, followed by postgraduate and then school education. The evidence shows that most of the studies use existing models to apply PET, such as TPACK; the only proposal for teacher training in the use of technology was the Spiral Model of ICT (information and communication technologies), TAC (technologies of learning and knowledge) and TEP (technologies of empowerment and participation) competencies. Regarding the application of PETs, 4 types of studies were observed: 1) based on co-work and interlearning 2) that promote the production of content and/or educational resources under a participatory approach 3) that use digital tools and/or spaces on the web and 4) that use Virtual Learning Environments (VLE).

The present work investigates the aquatic biodegradation of poly(3-hydroxybutyrate) (PHB)/nanoclay bionanocomposites containing PP-g-MA as compatibilizing agent. Both pristine and organically modified (Cloisite20A®) montmorillonite clay were used as fillers in different content (1 and 3 wt%). The bionanocomposites were prepared by melt intercalation in a single screw extruder. There after films (50x50x0.5mm) were prepared by compression and assessed by X-ray diffraction. Aquatic biodegradation of the films was appraised by visual inspection, optical microscopy, counting and identification of bacteria. Results proposed that the water of the Parnaíba River in the city of Teresina (Piauí, Brazil) has microorganisms (Pseudomonas putida and Pseudomonas aeruginosa) capable of degrading these bionanocomposite films, particularly the films with 3 wt% organoclay. Our data indicated the bacteria Pseudomonas aeruginosa degraded dexterously all the films. This work collaborates with the preservation of the environment and expands the use of bionanocomposites in expendable items with the development of films with properties favorable to biodegradation in aquatic environments. It is believed that PHB/clay/PP-g-MA films emerge as a promising alternative for the packaging industry. poly3hydroxybutyrate polyhydroxybutyrate poly hydroxybutyrate poly(3-hydroxybutyrate PHB/nanoclay PHBnanoclay PHB /nanoclay nanoclay PPgMA PP g MA agent Cloisite20A® Cloisite20A CloisiteA Cloisite A (Cloisite20A® 1 ( wt%. wt . wt%) extruder 50x50x0.5mm 50x50x05mm xxmm 50x50x0 5mm x mm (50x50x0.5mm Xray X ray diffraction inspection microscopy Piauí, Piauí (Piauí Brazil organoclay environments PHB/clay/PPgMA PHBclayPPgMA PHB/clay/PP industry (Cloisite20A xx 50x50x PHBclayPP

ABSTRACT This study verifies the association between the text sentiment of news items and the value of capital investments in the equity crowdfunding market. It also analyzes the influence of geographic attributes on the investments made. Based on data for 736 investments made in different ventures in the largest equity crowdfunding platform in one of the main emerging markets, this study’s results indicate that the attributes of ventures can affect the amount of capital invested in them. In addition, published mass media news items that have a greater quantity of positive words can stimulate larger investments in these ventures. On the other hand, the geographic distance between the entrepreneur and the investor can negatively affect the value of these investments. These results are relevant since they can contribute to the definition of fundraising strategies on the part of entrepreneurs and platform managers. market 73 markets studys s them addition hand managers 7

Abstract It is essential to think of the water crisis as being on a global scale, in the context of an environmental crisis that is also global. In this way, the present work looked at the issue of comparative water governance by randomly selecting some models from countries other than Brazil. Therefore, the objective pursued here is to describe and analyze the water governance models of Israel, South Africa, Mexico, Australia, Spain and the United States, as part of a larger survey that was conducted recently. It used the deductive method, with document analysis and bibliographic study and bibliographic review. The complexity of water governance was verified due to its multiple uses and because there are several public and private actors involved. The problem of scarcity, whether due to the absence of water or to its existence in a polluted form, is a fact in several nations requiring the application of integrated and supranational solutions. scale way Brazil Therefore Israel Africa Mexico Australia States recently method review involved scarcity form solutions

Abstract We evaluated the relationship between southern brown shrimp Penaeus subtilis (Pérez Farfante, 1967) yield and environmental parameters on the Amazon continental shelf. We analysed monthly fishing effort data (number of days spent at sea) and yield (kg of tails) collected between 1978 and 2009. A causal relationship had been expected between Amazon River discharge during the main period of shrimp occurrence in estuarine waters (considering post larval settlement and juvenile recruitment in second semester of each year) and adult abundance (represented by fishery yield in the first semester of the following year). We detected significant correlations between monthly river discharge and yield with a negative lag of four months, and between river discharge during the dry season (June to November) and yield in the following year. In general, low and high discharges during a given year were associated with high and low fishery yields, respectively, during the following year.

Abstract Changes in land use in the southern sierra and coast of Oaxaca have caused the deterioration of the forest ecosystem. Thus, given the scarce information on their impact on soil properties, the objective was to evaluate the effect of different land uses on the physical and hydrological properties of a Luvisol. The treatments evaluated were: pasture, agricultural, forest plantation, pine forest (control), and agricultural-livestock, located in the micro-watershed of the La Venta River, Copalita, Oaxaca. The parameters measured in the field were: hydraulic conductivity (K), bulk density (AD), total porosity (Po), which were obtained in undisturbed soil samples, mechanical resistance to penetration (MRP), initial infiltration (I a ), cumulative infiltration (I b ) and infiltration capacity (I c ). The determination of sand (S), silt (Si) and clay (Cl) particles, field capacity (FC), permanent wilting point (PWP), and available water (Aw) was performed on eight disturbed samples (four per depth) at each use, for a total of 40. Significant differences were observed in Po, MRP, AD, K, FC, PWP, Aw, and in the proportion of sand between land uses. K exhibited a significant positive correlation (p≤0.05) with PWP, Aw, S, I a , I b , and I c ; the last three were positively correlated. Agricultural, pasture and agricultural-livestock uses showed more negative impacts on infiltration and hydraulic conductivity, as well as on apparent density, porosity, mechanical resistance, and water availability; the forest plantation had a positive effect on the evaluated properties.

Resumen Los cambios de uso del suelo en la Sierra Sur y Costa de Oaxaca han provocado el deterioro del ecosistema forestal. Así, ante la escasa información sobre su impacto en las propiedades del suelo, se planteó el objetivo de evaluar el efecto de distintos usos del suelo en las propiedades físicas e hidrológicas de un Luvisol. Los tratamientos evaluados fueron: pastizal, agrícola, plantación forestal, bosque de pino (control) y agropecuario; ubicados en la microcuenca Río La Venta, Copalita, Oaxaca. Los parámetros medidos en campo fueron: conductividad hidráulica (Ks), densidad aparente (DA), porosidad total (Po) que se obtuvieron en muestras inalteradas de suelo; además de, la resistencia mecánica a la penetración (RMP), infiltración inicial (I a ), infiltración acumulada (I b ) y capacidad de infiltración (I c ). La determinación de las partículas de arena (A), limo (L) y arcilla (Ar), capacidad de campo (CC), punto de marchitez permanente (PMP) y el agua disponible (Ad) se realizó en ocho muestras disturbadas (cuatro por profundidad) en cada uso, para un total de 40. Se registraron diferencias significativas en Po, RMP, DA, Ks, CC, PMP, Ad y en la proporción de arena entre usos de suelo. Ks presentó una correlación positiva significativa (p≤0.05) con PMP, Ad, A, I a , I b e I c ; las tres últimas tuvieron correlación positiva. Los usos agrícola, pastizal y agropecuario evidenciaron más impactos negativos en la infiltración y conductividad hidráulica; así como en la densidad aparente, porosidad, resistencia mecánica y disponibilidad del agua; la plantación forestal registró un efecto positivo en las propiedades evaluadas.
