/ Corporalidades e corpo: um olhar sobre a autopercepção da imagem física entre mulheres adultas

Some attributes of women’s body self-perception associated with physical appearance, diet, physical activity, sedentary lifestyle, emotionality, well-being, discomfort, health, illness, among other elements of possible lifestyles have been intervened by idealizations or representations of beauty inflexible and exclusive that stigmatize, violate and break the will of these corporeities, based on the introjection of patriarchal and sexist discourses in their socio-historical and hegemonic events. An initial analysis will be presented with the corresponding narratives, the result of an anthropological and netnographic approach that observes the tuning of stereotyped bodies. Outlining a proposal for arrangements that break with physical and symbolic borders, that sustain communities of support and resistance in the face of the onslaught of stimuli that unify, standardize and despise the bodies that are not inserted in said models, for the sake of a logic of multiple consumptions and not from a perspective of self-care and acceptance.Algunos atributos de la autopercepción corporal de mujeres asociadas a la apariencia física, alimentación, actividad física, sedentarismo, emocionalidad, bienestar, malestar, salud, enfermedad, entre otros elementos de estilos de vida posibles han sido intervenidos por idealizaciones o representaciones de belleza inflexibles y excluyentes que estigmatizan, vulneran y quebrantan la voluntad de estas corporeidades, a partir de la introyección de discursos patriarcales y sexistas en su acontecer sociohistórico y hegemónico. Se presentará un análisis inicial con las narrativas correspondientes, resultado de una aproximación antropológica y netnográfica que observa la puesta en sintonía de cuerpos estereotipados. Esbozando una propuesta de acuerpamientos que rompan con fronteras físicas y simbólicas, que sostengan comunidades de apoyo y resistencia ante los embates de estímulos que unifican, estandarizan y desprecian los cuerpos que no se insertan en dichos modelos, en aras de una lógica de múltiples consumos y no de una perspectiva de autocuidado y aceptación.Alguns atributos da autopercepção corporal feminina associados à aparência física, alimentação,atividade física, sedentarismo, emocionalidade,bem-estar, desconforto, saúde, doença, entre outros elementos de possíveis estilos de vida têm sidointerferidos por idealizações ou representações de beleza inflexíveis e exclusivas que estigmatizam,violam e quebram a vontade dessas corporeidades, a partir da introjeção de discursos patriarcais e sexistas em seus acontecimentos sócio-históricos e hegemônicos.

LoRaWAN Network for Fire Monitoring in Rural Environments

The number of forest fires that occurred in recent years in different parts of the world is causing increased concern in the population, as the consequences of these fires expand beyond the destruction of the ecosystem. However, with the proliferation of the Internet of Things (IoT) industry, solutions for early fire detection should be developed. The assessment of the fire risk of an area and the communication of this fact to the population could reduce the number of fires originated by accident or due to the carelessness of the users. This paper presents a low-cost network based on Long Range (LoRa) technology to autonomously evaluate the level of fire risk and the presence of a forest fire in rural areas. The system is comprised of several LoRa nodes with sensors to measure the temperature, relative humidity, wind speed and CO2 of the environment. The data from the nodes is stored and processed in a The Things Network (TTN) server that sends the data to a website for the graphic visualization of the collected data. The system is tested in a real environment and, the results show that it is possible to cover a circular area of a radius of 4 km with a single gateway.This work was partially supported by the “Ministerio de Ciencia, Innovación y Universidades” through the “Ayudas para la adquisición de equipamiento científico-técnico, Subprograma estatal de infraestructuras de investigación y equipamiento científico-técnico (plan Estatal I+D+i 2017-2020)” (project EQC2018-004988-P), by Universidad de Granada through the “Programa de Proyectos de Investigación Precompetitivos para Jóvenes Investigadores.

Variabilidad patogénica de aislamientos de Pseudocercospora griseola en dos provincias de Ecuador

Common bean (Phaseolus vulgaris L.) is the most important edible grain legume in Ecuador. The Ministry of Agriculture, Cattle Raising, Aquaculture and Fisheries of this country estimated that 71,600 hectares were cultivated in 2012; of the sown area, 53% was dedicated to dry grain and the remaining 47% to fresh grain. Beans are an important source of income for farmers and food for thousands of Ecuadorian families. Crop performance and yield are affected by diseases such as angular leaf spot caused by Pseudocercospora griseola (Sacc.) Ferraris. The best alternative for disease control is to use resistant varieties. However, durability of field resistance will depend on the knowledge of angular leaf spot variability. In Ecuador, detailed and systematic studies on the variability of the angular leaf spot pathogen have not been conducted. For this reason, the pathogenic variability of 21 isolates of angular leaf spot, collected from the provinces of Carchi and Imbabura in the Ecuadorian Andes, was studied. Thirteen different pathotypes were identified, five of them showed compatibility with only the group of Andean differentials and the remaining eight showed compatibility with two groups of differentials (Andean and Mesoamerican). Race 63:0 was the most frequent and race 31:63 was the most virulent. None of the isolates were compatible with differential Cornell 49-242. Therefore, bean breeding lines in Ecuador would benefit by incorporating the Phg-2 resistance gene present in differential Cornell 49-242 .El fréjol común (Phaseolus vulgaris L.) es la leguminosa de grano comestible más importante en Ecuador. El Ministerio de Agricultura, Ganadería, Acuacultura y Pesca de este país estimó que en el 2012 se cultivaron 71,600 hectáreas, de las cuales el 53% del área sembrada se destinó a cosecha en grano seco y el restante 47% se cosechó en grano tierno. El fréjol constituye una fuente importante de ingresos económicos para los agricultores, y de alimento para miles de familias ecuatorianas. El rendimiento y la calidad del cultivo es afectado por enfermedades como la mancha angular causada por Pseudocercospora griseola (Sacc.) Ferraris. La mejor alternativa de control de esta enfermedad es el uso de variedades resistentes. Sin embargo, la durabilidad de la resistencia dependerá del conocimiento de la variabilidad del patógeno causante de la mancha angular. En Ecuador no se han realizado estudios en forma detallada y sistemática relacionados con la mancha angular. Por tal razón, se estudió la variabilidad patogénica de 21 aislamientos de Pseudocercospora griseola, colectados en las provincias de Carchi e Imbabura de los Andes ecuatorianos. Se identificaron trece diferentes patotipos, cinco de ellos compatibles únicamente con el grupo de diferenciales andinos y los ocho restantes compatibles con los dos grupos de diferenciales (andinos y mesoamericanos). La raza 63:0 fue la más frecuente y la raza 31:63 fue la más virulenta. Ninguno de los aislamientos fue compatible con el diferencial Cornell 49-242. Por lo tanto, futuras líneas de fréjol en Ecuador se beneficiarían al introducir el gen de resistencia Phg-2 presente en el diferencial Cornell 49-242

Widely power-tunable polarization-independent ultrafast mode-locked fiber laser using bulk InN as saturable absorber

The growing demand of ultrafast mode-locked fiber lasers in the near infrared has boosted the research activity in this area. One of the most convenient ways to achieve passive mode locking consists of inserting a semiconductor saturable absorber in the laser cavity to modulate the losses. However, in such a configuration, the limited power range of operation is still an unsolved issue. Here we report the fabrication of an ultrafast, high-power, widely power-tunable and non-polarization-dependent mode-locked fiber laser operating at 1.55 μm, using an InN layer as saturable absorber. With post-amplification, this laser delivers 55-fs pulses with a repetition rate of 4.84 MHz and peak power in the range of 1 MW in an all-fiber arrangement
