Prototipo funcional de un sistema de clasificación para las cerezas de café castillo, en función de su etapa de maduración

Trabajo de InvestigaciónEn el siguiente proyecto de grado se desarrolla un prototipo funcional para la clasificación automatizada de café castillo en función de su etapa de maduración, el cual consta de un sensor de color RGB, una banda transportadora, un servomotor para el desvió de las cerezas de café y el microcontrolador atmega328p. Inicialmente se realiza una búsqueda de las tecnologías que se emplean para este proceso, posterior a esto se selecciona los dispositivos que se usaran, ya con esto, se hace el modelado 3D del prototipo en el software Autodesk Inventor, se simula el sistema en Proteus y se diseña el circuito impreso (PCB) en EasyEDA, después de esto se realiza la implementación del prototipo para finalmente hacer las pruebas de validación.INTRODUCCIÓN 1.

A percepção dos usuários sobre a oferta de programas de promoção da saúde e prevenção de doenças: o caso de uma operadora de autogestão The users' perception of a health promotion and prevention program offer: a self-management operator case

A coexistência do setor público e privado de saúde no Brasil é antiga e os arranjos percorridos têm contribuído para a construção de um sistema fragmentado e complexo. Na busca por estabelecer políticas setoriais em harmonia com o Sistema Único de Saúde, a Agência Nacional de Saúde Suplementar tem estimulado o desenvolvimento de programas de promoção da saúde e prevenção de doenças no setor. Essas ações são consideradas como um conjunto heterogêneo de estratégias na consolidação de políticas que visem à saúde da população. Este é um estudo de caráter qualitativo que objetiva analisar esses programas em uma operadora de autogestão, com o intuito de compreender se eles produzem dispositivos biopolíticos. Foram coletados os discursos dos usuários dos programas por meio de um roteiro semiestruturado e utilizou-se a técnica de análise de conteúdo. Os resultados mostram que se encontram em curso alguns processos de reestruturação da produção do cuidado, e os aspectos relacionais têm sido priorizados nesses programas. Essas ações configuram-se em dispositivos biopolíticos conduzindo formas de viver. É importante a existência de equilíbrio entre as práticas desses poderes e a produção de liberdade, atentando para que não haja intervenções biopolíticas arbitrárias e autoritárias na produção das ações de saúde.<br>The coexistence of public and private health care systems in Brazil is old and their arrangements have contributed to the construction of a fragmented system. In seeking to establish policies in agreement with the Brazilian Unifed Health System, the National Agency of Supplemental Health insurance has encouraged the development of programs for health promotion and disease prevention on the private sector. These actions are a heterogeneous set of strategies to consolidate policies aiming at the population's health. This is a qualitative study that analyzes these preventive programs in a private health insurance agency, to understand whether they produce bio-political devices. Speeches were collected from users of the programs through a semi-structured script using the technique of content analysis. The results show that some restructuring processes of care production are ongoing, and relational aspects have been targeted in these programs. These actions are configured in devices leading biopolitical forms of life. It is important to have balance between these powers and the production practices of freedom, noting that there is no arbitrary and authoritarian biopolitical interventions in the production of health actions

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
