Abstract An arteriovenous fistula (AVF) is an uncommon sequela of spontaneous arterial aneurysm rupture into the adjacent venous system. We describe the case of a 74-year-old patient who underwent endovascular treatment of a right iliac AVF caused by a ruptured common iliac artery (CIA) aneurysm and a distal left CIA aneurysm. Surgery preserved the lumbar and inferior mesenteric arteries because of the need to simultaneously exclude the hypogastric arteries. Dynamic fluid balance phenomena provoked by closure of the AVF are described. The patient had a benign postoperative course with normalization of the severe hemodynamic changes presented prior to the intervention and resolution of respiratory symptoms attributed to pulmonary arterial hypertension.

Resumo A fístula arteriovenosa (FAV) é uma sequela incomum de rotura espontânea de aneurisma arterial dentro do sistema venoso adjacente. Descrevemos, em um paciente de 74 anos, o tratamento endovascular de FAV ilíaca à direita por aneurisma de artéria ilíaca comum (AIC) roto associado a aneurisma de AIC distal à esquerda, em cuja cirurgia foram preservadas as artérias lombares e mesentérica inferior por necessidade de excluir simultaneamente as artérias hipogástricas. Foram demonstrados os fenômenos na dinâmica do balanço hídrico ocorridos em decorrência da interrupção da FAV. A evolução do paciente foi benigna, com normalização das graves alterações hemodinâmicas que apresentava e com desaparecimento dos sintomas respiratórios atribuídos à hipertensão arterial pulmonar.

ABSTRACT. The objective of this study was to evaluate performance, gastrointestinal morphometry, carcass, and non-carcass traits in lambs finished on different levels of canola grain in the diet. Twenty-seven Santa Ines lambs with an average initial weight of 19.33 ± 1.39 kg were given different levels of canola grain in the diet: 0, 8, and 16%. Weights and body condition scores were determined at the beginning, every 14 days and at the end of the experimental period. Animals were slaughtered to assess gastrointestinal morphometry, carcass and non-carcass traits. The statistical design used was completely randomized. The inclusion of canola grain showed a linear effect (0.723) for the width and height of ruminal papillae in the ventral region of the rumen. Intestinal villi and crypts showed a quadratic effect, with peaks of 0.62 µm and 0.43 µm, with the inclusion of 8 and 16%, respectively. When evaluating carcass traits, a decreasing linear effect was found for hot and cold carcass yield with 16% inclusion of canola. Canola grain can be used as an alternative in diets for finishing sheep up to 8% inclusion in the diet without affecting performance, ruminal and intestinal histometry, carcass, and non-carcass traits.

RESUMO A erva-mate é um produto florestal não-madeireiro importante no Sul do Brasil, sendo cultivada junto com espécies nativas devido à sua necessidade de sombreamento, o que contribui para a conservação e fixação do carbono na sua biomassa. Contudo, a determinação da biomassa é difícil, pois as estimativas não garantem a aditividade entre os compartimentos e a biomassa total acima do solo. Objetivou-se avaliar modelo aditivo (seemingly unrelated regression - SUR) e não aditivo (ordinary least squares - OLS) de biomassa para um povoamento de erva-mate, além de comparar seu estoque de carbono com outros tipos de uso do solo, consolidando o seu potencial frente às mudanças climáticas. Um total de 30 árvores foram cortadas, compartimentadas e pesadas em balança digital, a fim de ajustar quatro modelos de biomassa. Os estoques de carbono foram comparados com valores encontrados na literatura. O viés do modelo SUR foi inferior a 2 %, exceto para as folhas, enquanto, no modelo OLS, variou entre 1 e 14 %. O erro variou entre 23 e 49 % para o SUR e entre 31 e 50 % para o OLS. Os modelos ajustados por SUR garantiram acurácia e aditividade dos compartimentos. O plantio de Ilex paraguariensis estocou mais carbono que áreas de agricultura e pasto, removendo mais gás CO2, evidenciando a sustentabilidade desse sistema e favorecendo a estabilidade climática.

ABSTRACT Ilex paraguariensis is an important non-timber forest product in southern Brazil, where it is cultivated in association with native species, given its demand for shading, which contributes to the conservation and carbon fixation in its biomass. However, determining this biomass is difficult, since the estimates do not guarantee additivity between the compartments and the total aboveground biomass. This study aimed to evaluate additive (seemingly unrelated regression - SUR) and non-additive (ordinary least squares - OLS) biomass models in an Ilex paraguariensis stand and comparing its carbon stock with other land use types, consolidating its potential in the face of climate change. A total of 30 trees were cut, compartmentalized and weighed on a digital scale, and four biomass models were adjusted. The carbon stocks were compared with values found in the literature. The bias in the SUR model was less than 2 %, except for the leaves, while the bias in the OLS model varied between 1 and 14 %. The error ranged between 23 and 49 % for SUR, and between 31 and 50 % for OLS. The models adjusted by SUR ensured the accuracy and additivity of the compartments. The Ilex paraguariensis stand stored more carbon than agriculture and pasture areas, removing more CO2, evidencing the sustainability of this system and favoring the climate stability.

Resumo A literatura em Educação em Ciências aponta o potencial das Comunidades de Prática (CoP) em fomentar espaços que articulem Escola e Universidade na Formação Continuada de Professores. Entretanto, as indicações existentes para o cultivo dessas estruturas sociais são incipientes. No presente trabalho, propomos diretrizes para tal fim a partir da articulação de conceitos da Teoria Social da Aprendizagem de Etienne Wenger com resultados de uma pesquisa educacional de caráter histórico realizada com uma CoP voltada para a formação docente. As referidas diretrizes são apresentadas em forma de questões, em dez eixos temáticos, de modo a auxiliar profissionais da Educação no fomento e manutenção de relações comunitárias de aprendizagem.

Abstract The literature on Science Education suggests that Communities of Practice (CoP) can be a powerful tool to integrate Schools and Universities, especially for In-service Teachers. However, fostering such social structures is still a vague notion. In this paper, we provide guidelines to address this issue, using a combination of concepts from Etienne Wenger's Social Theory of Learning and results of an educational study that applied a historical method to investigate a CoP focused on teacher education. These guidelines are presented in the form of questions, grouped in ten thematic categories, so that educational professionals can better create and maintain community-based relations for learning.

ABSTRACT Pea crops are highly vulnerable to the negative impacts of climate variability and climate change because of its socioeconomic and environmental marginality and the poor use of technical tools such as agroclimatic information. Therefore, in order to understand the local pea grower’s perception of agroclimatic risk, participatory mapping was implemented into the rural area of the municipality of Fusagasuga. Edaphoclimatic constraints and opportunities for pea crops were identified. This started with the dissemination of local climatic data and thematic cartography related to biophysical variables, such as elevation and slope. The local descriptions of soil characteristics were defined with the community to identify areas with the most and the least limiting soil conditions for pea crops. In addition, the areas with greater susceptibility to water deficits and water excess were identified. This paper focused on the methodological and pedagogical process generated for the identification of agroclimatic risks. The results showed how participatory learning empowers communities with information to improve their knowledge of the territory. This approach contributes to the adaptative capacity for extreme weather events since it provides elements for community organization to overcome risks. The participatory approach identified Aguadita, Bermejal, Tierranegra, La Palma, Bochica, Batan, Santa Lucía, El Guavio and El Carmen as low-risk areas for pea production because of the soil advantages and low occurrence of water deficits and excess water.

RESUMEN El cultivo de arveja es un sistema productivo altamente vulnerable a los impactos negativos de la variabilidad y el cambio climático, debido a su marginalidad socioeconómica y ambiental, así como a la poca utilización de herramientas técnicas como la información agroclimática. Por ello, con el propósito de entender la percepción del riesgo agroclimático por parte de productores de arveja, se presenta una experiencia en cartografía participativa implementada en la zona rural del municipio de Fusagasugá. Se identificaron limitantes y oportunidades edafoclimáticas del municipio para el establecimiento del cultivo. El ejercicio partió de la socialización de datos climáticos y cartografía temática relacionada con variables biofísicas como elevación y pendiente para, posteriormente, identificar las áreas del municipio con los suelos más y menos limitantes y las áreas con mayor susceptibilidad a déficit y exceso hídrico. El artículo hace énfasis en el proceso metodológico y pedagógico llevado a cabo durante el ejercicio de identificación de riesgos agroclimáticos. Los resultados evidencian cómo el aprendizaje participativo empodera a las comunidades con información que permite un mejor conocimiento del territorio, lo que contribuye a aumentar su capacidad adaptativa por cuanto se proveen elementos en torno al riesgo para la organización comunitaria. La aproximación cartográfica participativa permitió identificar a las veredas Aguadita, Bermejal, Tierranegra, La Palma, Bochica, Batan, Santa Lucía, El Guavio y El Carmen como las más aptas para la producción de arveja debido a unas condiciones edáficas favorables y una baja ocurrencia de eventos de déficit y exceso hídrico.

ABSTRACT: Current available soil information allows building baselines to improve research, such as sustainable resource management; however, its use requires analysis of accuracy and precision that describes specific variables on local and global scales. Therefore, this study evaluated differences in the spatial distribution of water retention capacity (WRC) of the soil at a depth of 0.3 m, calculated from local general soil surveys and the global gridded soil information system (SoilGrids), using detailed or semi-detailed soil surveys as a reference, in two regions of Colombia (A and B). The qualitative and statistical analyses evaluated differences in WRC surfaces generated by the information sources. Neither information sources described WRC accurately, achieving correlations between −0.15 and 0.49 and average absolute errors between 9.65 and 19.52 mm for zones A and B, respectively. However, studies on the local scale remain within the ranges observed in the most detailed local studies. The use of products on the global scale is subject to regional analyses; nevertheless, they can be included as a covariate in digital soil mapping studies on more detailed scales.

Abstract Antimicrobial activity of honey has lately drawn researchers’ attention, especially due to the fact that its antimicrobial capacity has been proven. The aim of this study was analyzing bactericidal and bacteriostatic action in the pathogenic microorganisms Staphylococcus aureus, Escherichia coli and Candida albicans of honey samples from five regions of the state of Paraná. Candida albicans yeast showed to be more resistant to honey than the bacteria Escherichia coli and Staphylococcus aureus. The minimal inhibitory concentration found for the three microorganisms tested was 12.5% to 25%. The minimal bactericidal concentration, in its turn, was 25% for bacteria and 25% to 50% for yeast. The samples from the Southern area had the best results for both the minimal inhibitory and the bactericidal concentrations. Through physicochemical and phyto-chemical analysis, we observed that several factors are associated to the bactericidal capacity of honey. In conclusion, honey is an excellent bactericidal agent with a great biotechnological potential. Its properties are directly related to its geographic origin, which gives each type of honey its own characteristics.

Resumo: O setor varejista de supermercados é de grande importância na geração de empregos e captação de mudanças no comportamento dos consumidores. Mudanças tecnológicas e mercadológicas ocorridas recentemente no setor aumentam a necessidade do aprimoramento de técnicas para a mensuração do desempenho individual das redes e a construção de parâmetros de comparação relativa entre as unidades. O objetivo deste artigo é analisar a eficiência de uma amostra de 31 supermercados de pequeno porte da região oeste de Santa Catarina. O método utilizado para a avaliação da eficiência foi a análise envoltória de dados (DEA), com as variáveis: faturamento, número de funcionários, área de vendas e o número de checkout’s, nos anos de 2014 e 2015. Os resultados encontrados apontaram para um baixo percentual de unidades em máxima eficiência de escala e técnica para os dois períodos analisados. Outra ponto relevante é a identificação das variáveis que apresentaram desajustes para o alcance da eficiência máxima das unidades (área de vendas e número de funcionários), sugerindo a existência de capacidade ociosa de estrutura.

Abstract: The retail supermarket sector is one of the most important in the third sector. Besides being one of that most generates direct and indirect jobs, it is one of the first to capture changes in consumer behavior. Given the strong competition and constant evolution of the sector, it is necessary to improve techniques for individual performance measurement of the networks and the construction of parameters of relative comparison between the units. The aim of this article is to analyze the efficiency of a 31 supermarkets sample in Santa Catarina, using Data Envelopment Analysis (DEA). The variables used in the investigation were gross sales, the number of employees, sales area and number of checkout's in the period of 2014 and 2015. The results pointed out a low percentage of units at maximum efficiency for the two periods analyzed. Another relevant finding was that the variables that presented a mismatch to reach the maximum efficiency of the units was the “Sales area (m2)” and “number of employees“, suggesting the existence of idle structure capacity.

RESUMEN En el norte de la Guajira encontramos uno de los ecosistemas secos más importantes de Colombia desde el punto de vista sociocultural y ecológico. Esta condición genera una gran vulnerabilidad de sus sistemas agropecuarios a eventos climáticos extremos, razón por la cual varias acciones son requeridas para reducirla. Dentro de las acciones se encuentra el establecimiento de zonas de aptitud agroclimática, una fuente de acceso a información que permite tomar decisiones. El objetivo de este estudio fue realizar una zonificación agroclimática del municipio de Uribia (La Guajira) para sistemas de producción agrícola y especies de alimentación animal. Los criterios utilizados para realizar la identificación de las zonas de aptitud incluyeron: coberturas vegetales presentes, aptitud de suelos, almacenamiento de agua bajo estrés hídrico, condiciones regulares climáticas y un evento de déficit hídrico extremo. Las condiciones evaluadas registraron variaciones en la aptitud agroclimática desde enero a abril y desde agosto a noviembre. Bajo la condición de déficit hídrico extremo entre agosto y noviembre, el área apta para el establecimiento de sistemas de producción con especies agrícolas (tipo C3 y C4) fue menor (77.000 ha) comparado con el periodo de enero a abril (130.000 ha). Las categorías de aptitud agroclimática en Uribia no mostraron diferencias entre los períodos evaluados bajo condiciones de déficit hídrico promedio.

ABSTRACT One of the most important dry agroecosystems in Colombia is found in the northern Guajira region, which has native inhabitants (sociocultural aspect) and semiarid zones (ecological aspect). This condition has resulted in great vulnerability in agricultural production systems to adverse climatic events, which require large scale action. For example, the establishment of agroclimatic suitability zones are needed to access information, for decision-making. The aim of this study was to carry out agroclimatic zoning in the municipality of Uribia (La Guajira) for agricultural production systems and animal feed species. The criteria used to identify the agroclimatic suitability zones included: plant coverage present in the municipality, soil suitability, water storage under water stress, regular conditions found in the municipality, and an extreme water deficit event. The evaluated conditions showed variations in agroclimatic suitability during the periods January to April and August to November. During an extreme water-deficit event between August and November, the suitable area for the establishment of production systems with plant species (type C3 and C4) was smaller (77,000 ha) than in the period January to April (130,000 ha). The agroclimatic suitability categories in Uribia did not exhibit differences between the evaluated periods under average water-deficit conditions.

RESUMO Objetivo: Reportar o uso de duas técnicas (radiocirurgia e vertebrectomia em bloco) no mesmo paciente, para o tratamento de metástases de um hemangiopericitoma intracraniano em dois locais da coluna. Hemangiopericitomas intracranianos são raros, consistindo em cerca de 2,4% dos tumores da meninge e menos de 1% de todos os tumores do sistema nervoso central, e metástases para a coluna são ainda mais raras: as maiores séries de casos publicada tinham 5 e 7 casos. Métodos: Um homem de 37 anos com diagnóstico de hemangiopericitoma intracraniano foi encaminhado para resecção em bloco de lesão metastática em T12 com a técnica de Tomita. Resultados: A doença evoluiu com metástase em T2, tratada com radiocirurgia (dose de 1600 cGy). O paciente morreu 1.706 dias após a resecção em bloco de T12 e 1.324 dias após a radiocirurgia de T2, livre de recorrência nessas localizações, devido a progressão sistêmica da doença (para fígado e sistema nervoso central). Conclusão: Este é o primeiro caso na literatura no qual duas técnicas diferentes foram usadas pra tratar lesões metastáticas da coluna de hemangiopericitoma intracraniano, único pelo uso de duas técnicas de tratamento no mesmo paciente. Nível de evidência V, relato de caso.

ABSTRACT Objective: To report the use of two techniques (radiosurgery and en bloc vertebrectomy) on the same patient for the treatment of two metastases in different sites of the spine arising from intracranial hemangiopericytoma. Intracranial hemangiopericytomas are rare, comprising approximately 2.4% of meningeal tumors and <1% of all tumors of the central nervous system. Metastases to the spine are even rarer: The largest case series reported in the literature has 5 and 7 cases. Methods: A 37-year-old man diagnosed with intracranial hemangiopericytoma was referred for a metastatic lesion in T12 and underwent en bloc resection using the Tomita technique. Results: The disease evolved with a metastasis to T2 treated by radiosurgery with 1600 cGy. The patient died 1,706 days after the en bloc resection of T12 and 1324 days after the radiosurgery of T2, and no recurrence occurred in these locations due to progression of the systemic diseases (liver and central nervous system). Conclusion: This is the first case reported in the literature in which two different techniques were used to treat metastatic lesions in the spine from an intracranial hemangiopericytoma and is unique for its use of two treatments in the same patient. Level of evidence: V, case report

Resumo As moscas-das-frutas (Diptera: Tephritidae) são importantes pragas de mangueira (Mangifera indica L.) em várias partes do mundo. Portanto, o principal objetivo deste estudo foi conhecer as espécies de moscas-das-frutas associadas a pomares comerciais de mangueira em uma região semiárida do Estado do Rio Grande do Norte, Brasil; relatar as espécies de importância quarentenária; discutir a influência do semiárido na distribuição das espécies; e verificar seus índices faunísticos. O estudo foi realizado no período de julho de 2011 a junho de 2014, em dez pomares comerciais de mangueira da cultivar Tommy Atkins, localizados no semiárido do Estado do Rio Grande do Norte, região Nordeste do Brasil. As moscas-das-frutas foram capturadas com auxílio de armadilhas McPhail plásticaS, tendo como atrativo proteína hidrolisada de milho a 5% (Bio Anastrepha®). Coletas de frutos de manga também foram realizadas. Uma análise faunística foi realizada para caracterizar as comunidades. Oito espécies de moscas-das-frutas (Anastrepha spp. e C. capitata) foram capturadas. A espécie C. capitata apresentou a maior distribuição geográfica e foi a única que infestou frutos de manga. A análise faunística mostrou que a maioria dos pomares apresenta baixa riqueza de espécies, e C. capitata foi a mais frequente e predominante nos pomares.

Abstract Fruit flies (Diptera: Tephritidae) are important mango (Mangifera indica L.) pests in several parts of the world. Therefore, the main objective of this study was to know the species of fruit flies associated with commercial mango orchards in a semiarid region of Rio Grande do Norte state, Brazil; report the species of quarantine importance; discuss the influence of the semiarid environment on the distribution of the species and verify their faunistic indices. The study was carried out between July 2011 and June 2014 in ten commercial orchards of mango cultivar Tommy Atkins in the semiarid region of the state of Rio Grande do Norte, Northeastern Brazil. Fruit flies were captured in McPhail traps baited with 5% hydrolyzed corn protein (Bio Anastrepha®). Mangoes fruits were also collected. Faunistic analysis was performed to characterize the populations. Eight fruit fly species (Anastrepha spp. and C. capitata) were captured. The species C. capitata had the highest geographic distribution and was the only one to infest mangoes. The faunistic analysis showed that most of the orchards had low species richness and that C. capitata was the most frequent and predominant species.

Resumen Se utilizó el modelo regionalizado de lluvia Regionalisierte Niederschlage (Regnie) para interpolar la lluvia y temperatura media del aire de las regiones Andina, Caribe y Pacífica de Colombia. Este modelo integró los datos de la pendiente y exposición del terreno obtenidos del modelo digital de elevación, así como los promedios climatológicos de 1440 series de precipitación y 258 series de temperatura registradas en igual número de estaciones meteorológicas de superficie para cada variable. Se establecieron los modelos de regresión lineal múltiple de la precipitación media anual y temperatura media anual del aire, además se utilizaron herramientas de geoprocesamiento para la generación de las superficies interpoladas. Los estadísticos de prueba de las superficies Regnie fueron similares a los obtenidos con interpolaciones con los métodos Spline e IDW para precipitación (coeficiente de determinación 0.81 y error medio de 55.6 mm) y mejores para la temperatura media (coeficiente de determinación 0.99 y error medio de 0.02°C).

Abstract A regionalized rain interpolation model: Regionalisierte Niederschlage (REGNIE) was implemented to interpolate rain and average air temperature for the Andean, Caribbean and Pacific Regions in Colombia. This model integrated terrain slope and aspect obtained from the digital elevation model and the climatological average of 1440 precipitation time series and 259 temperature time series registered in the same number of weather stations for each variable. Multiple linear regression models of annual rainfall and annual average air temperature were obtained according to the model and geoprocessing tools were used for the generation of interpolated surfaces. Statistical results of REGNIE surfaces were similar to those obtained with SPLINE and IDW methods for precipitation (determination coefficient of 0.81 and 55.6 mm mean error) and better for average mean temperature (coefficient of determination 0.99 and average error of 0.02 °C).
