Analyzing the conditions of use and selecting which technology is more efficient to apply is required when transmitting information through wireless networks.The Internet of Things (IoT) has gained traction in industry and academia as a paradigm in which information and communication technologies merge to deliver unique solutions by detecting, actuating, calculating, and sharing massive volumes of data via embedded systems. In this scenario, Low-Power Wide-Area Networks (LPWAN) appear to be an attractive solution for node connectivity. Typical IoT solutions demand flexible restrictions for wireless communication networks in terms of data rates and latency in exchange for having larger communication ranges and low energy consumption. Nonetheless, as the amount of data and data speeds demanded for particular applications increase, such as image transmissions, IoT network connectivity deteriorates. This paper proposes a communication architecture for image transmission across LPWAN networks utilizing LoRa modulation. The framework combines image processing techniques (classification, compressive sensing (CS), and reconstruction) with an investigation of LoRa modulation parameters using a Software-Defined Radio (SDR) environment. The results show that is possible to communicate an image of 128×128 pixels with four packets and one frequency channel in 2.51 s.
Evaluación del efecto de Lactobacillus spp. en el desarrollo del intestino delgado en pollos de engorde Lactobacillus spp. effect evaluation in the small intestine development in broiler chickens Resumen Los probióticos del tipo Lactobacillus spp. son considerados alternativas promisorias para reemplazar los antibióticos como promotores de crecimiento (APC) en las explotaciones avícolas, ya que influyen en el desarrollo poseclosión del tracto gastrointestinal (TGI) y en su ecología microbiana. En este estudio se evaluó la morfometría del intestino delgado en pollos de engorde al suministrar 0.5mL/L de un producto comercial a base de Lactobacillus spp. Se utilizaron 200 pollos machos de un día de edad, de la línea Avian Cobb 48, los cuales se distribuyeron, con un diseño completamente al azar, en dos grupos, denominados control y experimento; ambos grupos fueron mantenidos en condiciones similares de alimentación, manejo y sanidad. A los días 7, 15 y 35 de edad se realizó el sacrificio y la necropsia; se disectaron segmentos de duodeno, yeyuno e íleon para su procesamiento con la técnica de coloración de Hematoxilina-Eosina (H-E). Los cambios morfométricos de longitud, ancho y cantidad de vellosidades fueron evaluados utilizando un microscopio trinocular con cámara digital Moticam®. Los datos se analizaron usando el programa SPSS versión 19; se realizaron comparaciones de los promedios a través de estadística descriptiva y una prueba ANOVA (p<0,05); se observaron diferencias estimadas significativas (p<0,05) a favor del grupo experimento en el desarrollo poseclosión de los segmentos yeyuno e íleon. Palabras clave: desarrollo intestino; Lactobacillus; pollos de engorde; promotor; vellosidad (DeCS). Abstract The probiotic Lactobacillus spp. type, are considered promising alternatives to replace the use of antibiotics as growth promoters (APC) in poultry farms, due to their influence in the gastrointestinal tract (GIT) poseclosion development and in their microbial ecology. Thereof in this study the morphometry of the small intestine in broilers to provide with 0.5 mL/L of a commercial product based on Lactobacillus spp. were evaluated. 200 male chickens a day old, from the Cobb Avian 48 line were used, distributed Evaluación del efecto de Lactobacillus spp. en el desarrollo del intestino delgado en pollos de engorde
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
