Varal automático

O varal inteligente é um varal que leva as roupas que estão estendidas e desloca elas para uma parte segura longe da chuva. Através do sistema inteligente de sensores com o auxílio de um motor, o mesmo atua captando fenômenos climáticos como sol e chuva e levando as roupas para uma parte coberta, dessa forma poupando tempo e a presença do ser humano. O projeto foi feito através do referencial teórico e prático de Flávio Guimaraes, Sergio Luiz Stevan Junior e Daniel Thomazini. O projeto em desenvolvimento é a produção e reprodução de um varal automático. O intuito é fazer com que de forma automática as roupas estendidas sejam levadas a uma parte coberta fazendo com que a roupa não molhe. A estrutura básica do varal será feita em aço carbono, e terá uma área de ocupação de 2,4 m2. Desta estrutura total, somente uma parte dela se movimenta, que é a parte onde as roupas estão, a parte de apoio do varal no chão, continuará estática. Para a locomoção das roupas foi feito um trilho, que funciona semelhante aos portões eletrônicos residenciais que puxam a estrutura através de uma cremalheira acoplada ao varal e ao motor. O motor utilizado é o de vidro elétrico de 12v para puxar a parte móvel do varal. Foram utilizadas rodinhas de ferro para deslizarem o varal pelo trilho. O local seguro onde a roupa é conduzida, é uma espécie de telhado onde a roupa fica embaixo e pode continuar secando. Para completar a dinâmica entre sensor e motor, foram utilizados 1 (um) arduino Uno, 2 (dois) relés 250VAC 10A, Jumpers (condutores elétricos), e 2 (dois) sensores de final de curso, que indicam quando o trilho está chegando ao fim, como um sensor de estacionamento de automóvel. Para que os sinais emitidos pelos sensores trabalhem em conjunto com o motor, foi feita a programação que é processada pelo arduino para emitir a informação vinda do sensor para o atuador, neste caso, o motor. A captação de informações sobre a umidade e claridade do dia, para saber se está chovendo ou se está escurecendo, é feita por dois principais sensores. Estes sensores são: um sensor de luminosidade LDR que fica responsável pela medição de luz do ambiente, e o outro é o módulo sensor de chuva que é responsável pela detecção de chuva ou qualquer outro tipo de líquido que possa vir a molhar a roupa. A partir do desenvolvimento prático, o trabalho está com o estrutural pronto, já pintado e a parte eletrônica concluída com sensores captando e atuando quando necessário

MÃO ELETROMECÂNICA

O então resumo trata-se das abordagens, especificações e detalhes acerca da confecçãode uma mão eletromecânica. A ideia foi pensada inicialmente a fim de relacionar aproblemática – dificuldade enfrentada pelos indivíduos que perdem essa parte domembro superior, seja por ocasiões acidentais ou procedimentos médicos – com asvariadas temáticas vivenciadas através do curso técnico em eletromecânica integrado aoensino médio (ofertado pelo câmpus Blumenau do IFC – Instituto Federal Catarinense),no que diz respeito à elétrica e à mecânica, principalmente. Nesse sentido, certasdisciplinas estudadas – como Projeto Integrador, Automação Industrial, Eletrotécnica,Desenho Técnico, AutoCAD, Gestão Controle da Qualidade e etc – tornam-seessenciais para que a análise das propostas e intenções debatidas fossem elencadas,tendo importantes fundamentações bibliográficas para fundamentar a relevância epretensões pensadas. Assim sendo, foi comprovado o indispensável papel exercido eexecutado através das mãos. Composta por 5 (cinco) dedos na normalidade, que contamcom terminações ósseas separadas e diferenciadas por falanges (que garantem odobramento e movimentos básicos dos dedos), são de tamanha importância para osseres humanos, uma vez que é por meio delas que se desempenha funções e atividadesconsideradas básicas, como por exemplo: segurar algo, beber um copo d’ água,caminhar de mãos dadas, realizar tarefas e trabalhos manuais, dentre outras ocasiões amais. Por meio disso, iniciaram-se o processo de organização do grupo para seadequarem aos prazos e seguir de maneira centrada os cronogramas pré-definidos nopontapé inicial de definição do protótipo. A metodologia a ser seguida refere-se aomodo e de que forma será solucionado e retratado o problema exposto. Por isso,definiu-se que o projeto seria aplicado em uma luva, que serviria como base para as aplicações. Nessa perspectiva, foram realizadas compras de maneira online, bem comoaquisições feitas em lojas físicas – como servomotores, que atuam como atuadores (ouseja, são os responsáveis pelos esforços mecânicos realizados); placa de arduíno,necessária para as programações inseridas a fim de executar aquilo que se espera;sensores de pressão e resistência, utilizados para definir a relaçãomovimento-espelhamento. Dessa forma, o conhecimento acerca do tema e daproblemática enriqueceu as perspectivas dos integrantes do grupo, tendo como destaqueos aprendizados sobre softwares simuladores – AutoCAD e Inventor –, impressão 3D –tecnologia de ponta que serviu de suporte para representar o protótipo pensado –, alémde confirmar as intenções principiantes sobre a importante presença das mãos na vida decada indivíduo. Além do mais, outro ponto marcante e de destaque é a vivência na áreade eletromecânica que o projeto ofereceu de forma satisfatória para com os alunosenvolvidos, uma vez que essa era uma das principais intenções no início do ano letivo

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved

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

Effects of pre-operative isolation on postoperative pulmonary complications after elective surgery: an international prospective cohort study an international prospective cohort study

We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05–1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4–7 days or ≥ 8 days of 1.25 (1.04–1.48), p = 0.015 and 1.31 (1.11–1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care.

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data
