Resumo A disponibilidade de venda de alimentos no território pode influenciar no consumo alimentar da população. Entretanto, é importante compreender como as pessoas percebem o seu ambiente alimentar ...para se entender como essa disponibilidade afeta seu consumo em contextos distintos. O objetivo foi avaliar a percepção dos moradores de favelas brasileiras sobre o ambiente alimentar em suas vizinhanças. Estudo qualitativo, em que foram realizados grupos focais online guiados por um roteiro para reunir discursos coletivos sobre o acesso aos alimentos em favelas brasileiras. O convite ocorreu por meio das redes sociais e do contato com líderes comunitários e organizações não governamentais que atuam em favelas, por meio da técnica de amostragem “bola de neve”. Para a análise, foi utilizada a abordagem grounded theory (teoria fundamentada) e, como técnica, foi empregada a análise de redes temáticas. O acesso aos alimentos por moradores de favelas é permeado pela falta de recursos e elementos fundamentais para uma alimentação adequada e saudável, como: a falta de informação sobre alimentação; a renda insuficiente; e a baixa disponibilidade de estabelecimentos que comercializam alimentos saudáveis a preços acessíveis. São necessários programas e políticas públicas que incentivem a ampliação de equipamentos de segurança alimentar e nutricional, como hortas e feiras, e que aumentem a oferta de alimentos saudáveis com valores baixos nas favelas. Também são necessárias ações que abordem a complexidade das barreiras enfrentadas por moradores de favelas para ter acesso aos alimentos saudáveis.

Abstract Food availability in the territory can influence food consumption by the population. However, it is important to understand how people perceive their food environment to see how food availability affects consumption in different contexts. This study aimed to assess the perception of the food environment by Brazilian slum residents in their neighborhoods. This is a qualitative study, with online focus groups guided by a script in order to gather collective discourses about access to food in Brazilian slums. The invitation to participate in this study was made through social media, and community leaders and nongovernmental organizations with actions in slums were contacted using the snowball sampling technique. Grounded theory analysis was applied with the technique of thematic networks. Access to food for slum residents involves lack of resources and essential elements for an adequate and healthy diet, such as lack of information about food, low income, and low availability of stores that sell healthy food at affordable prices. Public programs and policies are required to encourage the expansion of food and nutritional security resources, such as vegetable gardens and markets, to increase the supply and sell healthy food at affordable prices in slums. Actions are also required to address the complexity of obstacles faced by slum residents in the access to healthy foods.
•Recycling and reuse are a micro-level strategy for the circular economy.•Ecoefficiency assessment in the adoption of circular economy at the micro-level.•Sensitivity analysis between economic and ...environmental gains in circular economy.
Industrial and economic growth activities induce an increase in the generation and emission of large amounts of polluting waste to the environment. However, the scarcity of natural resources in ecosystems denotes the importance of the practical application of Circular Economy (CE) at the micro level. This research aims to evaluate the environmental and economic advantages of adopting waste recycling and reuse processes based on the CE in four industrial companies in the metal-mechanical sector. Multiple cases studies were conducted, supported by direct observations of the production processes, in addition to document examination and interviews. In the data analysis, the companies' environmental and economic gains were calculated and compared. It was concluded that the implementation of closed-loop recycling by companies in the metal-mechanic sector is an important strategy to promote CE at the micro-enterprise level. In addition to generating a consistent financial return, it resulted in the reduction of environmental impacts in the abiotic compartment (contributing to the control of global warming and flora contamination); in biotic compartment (correct disposal of wastes does not affect terrestrial living beings); in water, (the disposal of industrial waste in water bodies); and elimination of emission of any nature into the air. Despite the evidence of economic gains and the reduction of the environmental impact, environmental gains were more significant at global levels. It is expected that these findings can encourage industry managers and researchers to implement closed-loop recycling at the micro level, in addition to making its CE actions transparent to the market and government, contributing to their competitive advantage.
To describe and analyze the healthiness of formal and informal food establishments in bus terminals of the metropolitan region of the state of Rio de Janeiro.
An audit was conducted in 156 formal and ...127 informal food establishments located in 14 bus terminals of the five most populous cities of the metropolitan region of Rio de Janeiro. Proportions of types of establishments and means (95%CI) of food availability indicators in formal and informal settings were calculated. For the formal setting, prices, proportions of accepted payment methods, days and hours of operation, and food categories with displayed advertising were described.
The healthiness of food establishments in bus terminals was low (less than 36%). On average, ultra-processed food subgroups were 250% more available for purchase than fresh or minimally processed food. Purchasing food at these places was convenient because several forms of payment were available, and the opening hours of the establishments followed the peaks of movement. In addition, 73.3% of the advertising referred to ultra-processed drinks, and the cost-benefit of buying ultra-processed food was better than fresh or minimally processed food.
The food environment of bus terminals in the metropolitan region of Rio de Janeiro promotes unhealthy eating. Regulatory public policies should focus on initiatives to limit the wide availability and advertising of ultra-processed food in spaces of great circulation of people.
The textile industry has been concerned with the need to address the environmental and ecological sustainability of the oceans, according to a set of principles designated as the Blue Economy. ...Likewise, the textile industry has been identifying cleaner production practices with the purpose of reducing water consumption and limiting the use of toxics namely for fabric dyeing, in order to limit the disposal of toxic effluents and prevent the contamination of rivers, and oceans. This study has the objective of evaluating the Eco efficiency of a textile industry that implemented Cleaner Production practices for water reuse, and the minimization of the usage of water and materials aligned with the Blue Economy principles. The study used a case study approach, involving data collection through observation, documental analysis and interviews. The study contributes for theory by relating Cleaner Production and Blue Economy, topics that are not often explored together. It also contributes to the managerial practice offering a real case of Cleaner Production and Blue Economy strategy, leading to the minimization of environmental impacts of 516.2 thousand tons per year in several domains, including the biotic, abiotic, water and air. 96.9% of the gains were observed in the use of water resources, including economic gains from water reuse, and from the commercialization of sludge as a by-product. Despite the investment of 771.5 thousand dollars in cleaner technologies a return on investments was achieved after 29 months. The study also favoured the elimination of pollutants in the effluents that are disposed in rivers, lakes and the sea, contributing to the improvement in the health conditions of local communities.

amidst the greatest health crisis in history triggered by COVID-19, this documental study was intended to understand the meanings individuals who have lost loved ones in this context assign to the ...phenomenon of suppressed funeral rituals.
based on the theory of grief, the corpus of this study was composed of documents published in digital media containing personal writings and reports of experiences freely and easily available to the public. Two researchers with expertise in the field used inductive thematic analysis to interpret data.
the experiences shared in the reports reflect the suffering experienced by the sudden death of a significant person, which is amplified by the absence or impediment to performing familial farewell rituals. The suppression or abbreviation of funeral rituals is a traumatic experience because family members are prevented from fulfilling their last homage to the loved one who has suddenly passed away, causing feelings of disbelief and indignation.
alternatives and new ways to celebrate passage rituals in emergencies of strong social commotion such as a pandemic are needed to provide support and comfort to family members, friends, and relatives. These rituals help survivors to overcome the critical moment, decreasing the risk of developing complicated grief.
Conceptually Cleaner Production seeks to integrate the continuous utilization of deterrent environmental approaches to processes, products and services aiming to rise efficiency and to minimize the ...risks to people and environment. Extant literature has shown that the implementation of Cleaner Production practices brings as a result economic and environmental gains. Nevertheless, very few studies link those savings to the Sustainable Development Goals, reason why this research aims to evaluate if the economic and environmental advantages coming from Cleaner Production adoption in the textile industry contributed to the Sustainable Development Goals. This was done through extensive review of the literature, complemented by the proposal of a theoretical framework confirmed through the development of two case studies. As a result, it was concluded that the adoption of Cleaner Production practices in Brazilian textile industries through technological innovation made it possible to highlight the economic and environmental gains relating those to Sustainable Development Goals 9, 12 and 15.
ObjectiveTo analyse the short-term effects of kinesio taping (KT) with tension (KTT) or without tension (KTNT) in older women with knee osteoarthritis (KOA), and compare them to controls who did not ...receive KT.DesignRandomised controlled trial.SettingUniversity physiotherapy school clinic.ParticipantsForty-five older women (fifteen participants per group) with 66.8 (±5.6) years and clinical diagnosis of KOA were assessed pre, post and 3 days after intervention.InterventionsParticipants were randomly allocated to KTT, who received two simultaneous applications of KT with tension on the knee and rectus femoris; KTNT, who received the same application as the KTT group, but without tension and a control group that attended a class on KOA.Primary and secondary outcome measuresPrimary outcome was pain intensity and secondary outcomes were knee-related health status, functional capacity, muscle strength and global rating of change.ResultsNo between-group differences were observed in pain after the first intervention (KTT vs KTNT: mean difference (MD), −1.8 points; 95% CI −4.2 to 0.5; KTT vs control: MD, −1.2 points; 95% CI −3.6 to 1.2; KTNT vs control: MD, 0.66 points; 95% CI −1.7 to 3.0) or 3 days later (KTT vs KTNT: MD, −1.3 points; 95% CI −3.7 to 1.0; KTT vs control: MD, 0.13 points; 95% CI −2.2 to 2.5; KTNT vs control: MD, 1.4 points; 95% CI −0.9 to 3.8). The lack of between-group differences was also found for secondary outcomes.ConclusionThe short-term use of KT with or without tension in older woman with KOA had no beneficial effects on pain and function. These findings call into question the clinical use of KT as a non-pharmacological therapy for this population.Trial registration numberNCT03624075.
β‐glucosidases play a pivotal role in second‐generation biofuel (2G‐biofuel) production. For this application, thermostable enzymes are essential due to the denaturing conditions on the bioreactors. ...Random amino acid substitutions have originated new thermostable β‐glucosidases, but without a clear understanding of their molecular mechanisms. Here, we probe by different molecular dynamics simulation approaches with distinct force fields and submitting the results to various computational analyses, the molecular bases of the thermostabilization of the Paenibacillus polymyxa GH1 β‐glucosidase by two‐point mutations E96K (TR1) and M416I (TR2). Equilibrium molecular dynamic simulations (eMD) at different temperatures, principal component analysis (PCA), virtual docking, metadynamics (MetaDy), accelerated molecular dynamics (aMD), Poisson‐Boltzmann surface analysis, grid inhomogeneous solvation theory and colony method estimation of conformational entropy allow to converge to the idea that the stabilization carried by both substitutions depend on different contributions of three classic mechanisms: (i) electrostatic surface stabilization; (ii) efficient isolation of the hydrophobic core from the solvent, with energetic advantages at the solvation cap; (iii) higher distribution of the protein dynamics at the mobile active site loops than at the protein core, with functional and entropic advantages. Mechanisms i and ii predominate for TR1, while in TR2, mechanism iii is dominant. Loop A integrity and loops A, C, D, and E dynamics play critical roles in such mechanisms. Comparison of the dynamic and topological changes observed between the thermostable mutants and the wildtype protein with amino acid co‐evolutive networks and thermostabilizing hotspots from the literature allow inferring that the mechanisms here recovered can be related to the thermostability obtained by different substitutions along the whole family GH1. We hope the results and insights discussed here can be helpful for future rational approaches to the engineering of optimized β‐glucosidases for 2G‐biofuel production for industry, biotechnology, and science.
