Development of a remote sensing and control system for greenhouse applications

Real-time monitoring provides reliable, timely information of crop and soil status, important in taking decisions for crop production improvement. This work presents a real-time monitoring and control system for climatological variables in greenhouse. The system has wireless communication capabilities, which allow it to cover extensive surfaces in real-time, without extra resources. The system implementation is based on the micro controllers “PIC18F4550” and “DSPIC 30F5011”, user interface was programmed under LINUX. The proposed system performance was compared with commercial Data Loggers, readings present a linear adjustment with R2=0.9656

PRODUÇÃO DE ESTUDOS EM ENFERMAGEM SOB O REFERENCIAL DA FENOMENOLOGIA

Objetivo: caracterizar a produção de estudos gerada pela pós-graduação e conduzidos segundo o referencial da fenomenologia. Metodologia: pesquisa documental, retrospectiva, de natureza quantiqualitativa, utilizando versão eletrônica dos Catálogos do Centro de Estudos e Pesquisas em Enfermagem (CEPEn) da Associação Brasileira de Enfermagem (ABEn) publicados no período compreendido entre 2003 e 2013. Resultados: identificado número considerável de estudos desenvolvidos por pesquisadores da área de enfermagem segundo o pensamento filosófico de Alfred Schutz e Martin Heidegger, nos quais a investigação dos modos possíveis do cuidar abre perspectivas para um novo olhar do cuidado na enfermagem. Conclusão: o quantitativo das publicações gerado pela pós-graduação reflete o interesse pelo referencial teórico, assim como a busca profissional pelo aprimoramento do entendimento do ser por meio dos postulados fenomenológicos.Descritores: Enfermagem; Fenomenologia; Cuidar

Incidencia de los proyectos de Vinculación con la Sociedad de la Universidad Politécnica Salesiana. Vol 2

Con este mismo título, en diciembre de 2021, apareció el primer volumen de este trabajo. La intención fue sistematizar algunos proyectos de vinculación que habían logrado impactos sociales en términos cualitativos y de innovación educativa. En esa oportunidad se presentó una obra con diez capítulos de reflexión, sistematización, análisis y descripción de la trascendental importancia que implica, para la UPS, la vinculación con la sociedad. Ahora, al cumplir la UPS 28 años de vida institucional, presentamos este segundo volumen, que recoge en 14 capítulos el trabajo de 3 docentes, administrativos, estudiantes e investigadores invitados de distintos campos científicos. Es la continuación de la sistematización de los proyectos de vinculación emblemáticos que se han desarrollado en las sedes de Cuenca, Quito y Guayaquil de la universidad. EN cada uno de ellos se podrá encontrar el esfuerzo que la UPS ha desarrollado en estos 28 años, desde su fundación, para conseguir transformaciones sociales. Fiel a su misión y visión institucional, ha desplegado un arduo trabajo en el capo científico, tecnológico y cultural, dándose a conocer como una institución de excelencia académica, producción científica, responsabilidad social y capacidad de incidir en el desarrollo de la sociedad ecuatorian

Long-term thermal sensitivity of Earth’s tropical forests

The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into long-term responses. Here, we analyze 590 permanent plots measured across the tropics to derive the equilibrium climate controls on forest carbon. Maximum temperature is the most important predictor of aboveground biomass (−9.1 megagrams of carbon per hectare per degree Celsius), primarily by reducing woody productivity, and has a greater impact per °C in the hottest forests (>32.2°C). Our results nevertheless reveal greater thermal resilience than observations of short-term variation imply. To realize the long-term climate adaptation potential of tropical forests requires both protecting them and stabilizing Earth’s climate

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Evidence of spatial clustering of childhood acute lymphoblastic leukemia cases in Greater Mexico City: report from the Mexican Inter-Institutional Group for the identification of the causes of childhood leukemia

BackgroundA heterogeneous geographic distribution of childhood acute lymphoblastic leukemia (ALL) cases has been described, possibly, related to the presence of different environmental factors. The aim of the present study was to explore the geographical distribution of childhood ALL cases in Greater Mexico City (GMC).MethodsA population-based case-control study was conducted. Children <18 years old, newly diagnosed with ALL and residents of GMC were included. Controls were patients without leukemia recruited from second-level public hospitals, frequency-matched by sex, age, and health institution with the cases. The residence address where the patients lived during the last year before diagnosis (cases) or the interview (controls) was used for geolocation. Kulldorff’s spatial scan statistic was used to detect spatial clusters (SCs). Relative risks (RR), associated p-value and number of cases included for each cluster were obtained.ResultsA total of 1054 cases with ALL were analyzed. Of these, 408 (38.7%) were distributed across eight SCs detected. A relative risk of 1.61 (p<0.0001) was observed for the main cluster. Similar results were noted for the remaining seven ones. Additionally, a proximity between SCs, electrical installations and petrochemical facilities was observed.ConclusionsThe identification of SCs in certain regions of GMC suggest the possible role of environmental factors in the etiology of childhood ALL
