Reporte de un caso clínico de latrodectismo en Ecuador y su revisión bibliográfica. El latrodectismo es causado por la mordedura de una araña del género Latrodectus, comúnmente llamadas viudas negras, araña del trigo o araña de poto colorado. Las especies L. mactans, L. thoracicus, L. hasselti, entre otras, pertenecen a este género, el cual está ampliamente distribuido a nivel mundial. (4) El veneno del género Latrodectus contiene α-latrotoxina, una neurotoxina que actúa a nivel presináptico del sistema nervioso autónomo (aumentando la liberación de acetilcolina.) produciendo un síndrome neurotóxico, el mismo que es de difícil diagnostico sino hay la sospecha clínica y el antecedente del encuentro con el artrópodo de ahí la importancia de conocer acerca de esta patología. El diagnóstico es clínico el tratamiento se reporta manejo del dolor y de soporte además del uso de antídoto anti - latrodectismo, el pronóstico es favorable: se reporta una letalidad entre 0 y 6% en distintas series (Jelinek, 1997; Schenone, 2003).

Esta investigación permite dar a conocer los riesgos físicos en las tareas de mantenimiento de una estación de radio base de telefonía celular. A pesar de que hasta la fecha las investigaciones realizadas anteriormente no presentan evidencia científica importante para indicar que estas radiaciones afectan al ser humano, estos análisis han determinado la existencia de límites de exposición a radiaciones no ionizantes, los cuales deben ser respetados por los trabajadores que realizan este tipo de trabajos. Las mediciones de densidad de potencia (s), densidad de campo eléctrico (e), densidad de campo magnético (H) realizadas para alturas (h) de 2 hasta 5 m en el lóbulo principal del emisor o antena donde existe la máxima ganancia determinaron un 32 % de los puntos medidos sobrepasan el límite permisible. Con estos valores se establecieron las distancias de seguridad y, por lo tanto, se determinó que: la altitud es inversamente proporcional a la densidad de campo magnético, eléctrico y de potencia.

El presente estudio, gira en torno a los establecimientos de alojamiento de la ciudad de Puyo, registrados en el Ministerio de Turismo, que cuentan con una categoría que permite su operación y tiene por objetivo medir la satisfacción y calidad del servicio aspecto clave que contribuye al posicionamiento tanto del establecimiento como del destino, para tal efecto se aplicó una encuesta modelo Servqual en las dimensiones de tangibilidad, fiabilidad, capacidad de respuesta, confianza y empatía, también se planteó los métodos estadísticos coeficiente correlación y Análisis de la varianza ANOVA unifactorial, para resolver las hipótesis del caso, los resultados determinaron que el índice de la calidad refleja a la Tangibilidad como la dimensión con menor promedio de percepción por parte del cliente, el cálculo del promedio general de las 5 dimensiones valoradas sobre un valor de 4.06 representa 81.44% de los clientes que perciben un buen servicio de calidad de acuerdo al grado de porcentaje 0-100% de la escala de Likert. Se concluye que las brechas más altas con la percepción del cliente y su expectativa son tangibilidad (-0,06), fiabilidad (-0,06) y empatía (-0,05), siendo los puntos sobre los cuales es necesario implementar estrategias de calidad en cuanto al análisis de las hipótesis, se concluye que, existe un coeficiente de correlación sobre la calidad del servicio y la satisfacción del cliente con un 0,828 y una significativa de 0,01 y sobre el análisis de la correlación multivariente algunas dimensiones del calidad tales como tangibilidad y capacidad de respuesta, no son relacionantes con la percepción del cliente.

This work aims to contribute to the development of improvements in the logistics adopted for the selective collection of recyclable material, as well as in the development of environmental education work. For this purpose, a pilot project of selective collection is proposed, using a Voluntary Delivery Point (VDP) to replace door-to-door collection logistics, together with an intensive education campaign for the use of the VDP. In its first phase of the project, carried out on two streets in the Campos Elíseos neighborhood of Poços de Caldas-MG, the viability of the implementation of the VDP was verified from the data obtained by performing an analysis before and after the implementation of the VDP. The results show a reduction of 70% in the collection time, a 40.4% fall in the distance traveled by the collectors, as well as the diesel economy. 

The objective of this study was to evaluate the growth, development and productive aspects of strawberry plants submitted to inoculation of Azospirillum brasilense, Bacillus amyloliquefaciens and Trichoderma asperellum with and without association with Silicon (Si). The experimental design was randomized blocks, with eight treatments, three blocks, three replicates per treatment for each block. Growth and development evaluations were performed at 30 and 60 days after transplanting (DAT) of the seedlings. For the evaluations of the productive aspects, the ripe fruits collected were submitted to the physical-chemical analyzes. The dry biomass accumulation was determined by dry mass of the shoot (MSA), dry mass of the crown (MSC), dry mass of the roots (MSR) and total dry mass (MST). At 30 DAT, no significant difference was observed between treatments. At 60 DAT the treatments B. amyloliquefaciens (T3) and Si (T5) had the highest chlorophyll indexes (CI). The treatments T. asperellum and Si (T6), T3 and T5 presented the highest averages for MSA, whereas the T5 treatment had the highest mean for MSC and the T6 treatment presented the highest mean for MSR and MST. It was concluded that the treatments influenced the growth, development and accumulation of dry biomass in the strawberry, not having influence on the physical-chemical parameters of the fruits.

This article focuses on the study of the socio-spatial dynamics of vulnerable areas, in order to produce alternatives that aim at improving the quality of life of its residents, since these areas are affected by poverty, violence, diverse risks, among other determinants, as well as being areas that are not constantly included in municipal urban planning plans. Thus, it is necessary to study the socio-spatial dynamics of these areas through the urban planning bias. For this purpose, the case of the neighborhood of Cristo Rei, located in the city of Montes Claros / MG, was studied, since the city is of medium size and has great socioeconomic importance for the north of Minas Gerais. The Cristo Rei City neighborhood is located in the central region of the city and has a subnormal cluster within its boundaries, which makes it an even more vulnerable area. The approach here is based on the principle of social learning, that is, it seeks different alternatives for the aforementioned neighborhood, which are a product of the dialogue between social interest (popular participation) and public interest (municipal government). Finally, urban planning associated with social learning has proved to be an important research tool capable of bringing together several complex themes about the territory in question and, thus, can point to transforming principles for other vulnerable regions of the city of Montes Claros and the region

 As pimentas do gênero Capsicum são originárias das Américas, de onde posteriormente foram disseminadas ao redor do mundo, sendo um produto de grande valor de mercado. Com esse cenário vem sendo desenvolvidas diversas técnicas de melhoramento genético, onde se procura produzir cultivares que melhor atendam determinadas finalidades e que se adaptem melhor as características edafoclimáticas de determinada região. O presente trabalho objetivou estudar as características morfológicas de oito genótipos de pimentas Bode nas características edafoclimáticas da macrorregião de Ceres-GO. Dos oito tratamentos de pimentas, três são cultivares já disponíveis no mercado: Isla pimenta Arari bode amarela, Isla pimenta Tupã bode vermelha e Feltrin pimenta bode Salar amarela; cinco são linhagens de pimentas do tipo bode desenvolvidas através do método SSD pelo Instituto Federal Goiano – Campus Ceres: IFET 1634, IFET 1636, IFET 1638, IFET 1642 e IFET 1644. As variáveis analisadas foram: tamanho da planta, diâmetro da copa, período de floração, comprimento do fruto, diâmetro do fruto, comprimento do pericarpo, massa de frutos, número de frutos por planta, número de sementes por fruto, teste de condutividade elétrica de sementes e teor de água. A linhagem IFET 1638 e a cultivar Vermelha Isla apresentaram melhores resultados para altura de planta e diâmetro de copa, diâmetro de frutos e número de sementes por fruto, enquanto que, as linhagens IFET 1634 e IFET 1642 foram mais precoces na floração. As linhagens de pimentas bode IFET 1638 e IFET 1644 são mais promissoras. Em relação à qualidade de sementes todos os genótipos apresentaram resultados semelhantes.Palavras chave: 

The main objective of this study was to analyze, through a review of the pertinent literature, the necessity and importance of the psychotherapeutic work in overweight individuals who have Binge Eating Disorder, considering the difficulty of these people in the engagement in processes of weight loss, and maintenance. The proposed theme is extremely relevant, given the increase in overweight and obesity in Brazil and worldwide. We sought to verify how the psychologist's work can assist the subject in changing eating habits and behaviors and lso to evaluate the evidence on the effectiveness of psychotherapeutic follow-up in the weight loss process of these subjects. It is a bibliographical research, through a review of relevant literature on the subject, in periodicals, theses, articles, books and electronic libraries, published in the last 10 years. The databases used for the bibliographic survey are SCIELO and LILACS, as well as books that refer to the proposed theme. After surveying the existing works in these bases from the key words, those that did not fit within the parameters stipulated and defined in the project were disregarded. From the bibliographical survey, it was found that it is quite common that the Binge Eating Disorder be found in overweight individuals. It was possible to identify that, compared to other psychotherapeutic approaches, Cognitive Behavioral Therapy is the one that has more studies related to the individuals with Binge Eating Disorder. Regardless of the modality of psychotherapy, is a consensus the importance of the work of the psychologist in the treatment of these subjects, which will preferably integrate a multidisciplinary team. 

 This study has the purpose of verifying the axial compressive strength of mortars manufactured with different additives, which are: hydrated lime, liquid detergent and white glue (PVA). For the preparation of this work, a bibliographical review was carried out and the laboratory experiment was set up. The traces of the three additives were the same, modifying only the addition of the additive. The first mortar was produced with liquid detergent, the second had the addition of white glue (PVA) and the third was using traditional hydrated lime. After production, the specimens were molded. After molding, the specimens were stored in the laboratory until adequate cure was obtained, and then they were disrupted with the aid of an automated hydraulic press. With the results of the resistance of the test specimens, it was observed that the resistance of the mortars with liquid detergent and with white glue (PVA) were equivalent, whereas the one composed of hydrated lime acquired a lower resistance.
