The Sustainable Development Goals (SDGs) provide a comprehensive framework to guide actions towards a more sustainable future, emphasizing the need for sustainable production and consumption patterns (SDG 12), urgent measures to combat climate change and its impacts (SDG 13), and ensuring inclusive, equitable, and quality education (SDG 4). In this context, environmental education (EE) becomes crucial to empower present and future generations to address complex environmental challenges. Promoting EE can be enhanced through Chemistry education, encouraging the use of biomass as a primary energy source, a significant ally in addressing the SDGs. This study integrates experimental and educational chemical knowledge on the pyrolysis reaction of black pepper waste, aiming at higher education in Chemistry in an Environmental Chemistry class at Federal University of Espírito Santo. It aims to provide an in-depth understanding of chemical kinetics, connected to sustainable development through the theoretical-methodological strategy of problematized experimental activity (PEA). The developed PEA comprised five theoretical-experimental classes, including thermogravimetric analysis (TGA) simulation and pyrolysis furnace testing. The results indicate significant learning in Chemical Kinetics and themes related to the pyrolysis process associated with sustainable development, highlighting the contribution of the utilized PEA.

The article aims to address the use of the theoretical-methodological teaching strategy, Problematized Experimental Activity (PEA), to introduce a method employed in chemometrics, called Principal Component Analysis, through digital images linked to a smartphone app (REDGIM®). The application of a didactic workshop occurred in the pandemic context of SARS-CoV2, in remote teaching, with students of the undergraduate course in Chemistry of a public University of Espírito Santo. The students were divided into two groups and developed solutions to a proposed problem, working with the themes: differentiation of false and true banknotes, and recognition of patterns in vegetable oils. The groups presented promising results in terms of learning in the development of their experimental methodologies and were able to have contact with analysis of chemical problems that are still little explored in the undergraduate course.

O presente artigo busca compreender o início do processo de internacionalização da Construtora Norberto Odebrecht (CNO), em fins dos anos 1970, a partir da política externa brasileira que buscou projetar o país enquanto um paymaster regional. Voltamos nossas lentes para a atuação da empreiteira no Peru, a partir das obras da usina hidrelétrica de Charcani (1979), e no Equador, com as obras de irrigação na península de Santa Elena (1988). Para tanto, nos valemos de materiais publicados internamente pela construtora, as revistas Odebrecht Informa, em diálogo com outras fontes e a literatura da integração regional. Objetivamos, com isso, demonstrar de que forma o Estado brasileiro, nos anos 1980, se vale das atividades da construtora para cristalizar sua atuação no continente e se projetar enquanto um paymaster regional.

During the last 150 years or more, society has witnessed many key scientific discoveries and inventions, which have dramatically improved not only our quality of life, but our lifespan. However, the motivation of scientists to provide scientific advances has generally not been the achievement of these goals, but mainly driven by research curiosity. Fundamental scientific studies, also known as basic science, have paved the way to a society of knowledge by means of continuously evolving education systems, and have led to applied science and technological breakthroughs changing the World. However, without basic science such life-changing advances would not happen, which is poorly understood by the society. Having this in mind, chemists and biochemists working in a chemistry network highlight here examples of how basic science has played a crucial role and led to major breakthroughs. In seven short stories, the authors describe cases and historical events where basic research discoveries have advanced science, and opened avenues for future achievements. Investment in basic science is crucial for a nation’s health and wealth. The support of scientists driven by curiosity ultimately can benefit the whole of society, not only in innovative products, but also in the improvement of the understanding of our own lives.

RESUMOEste trabalho realizou um levantamento sobre o uso de plantas medicinais na cidade de Picos-PI, identificou as plantas cultivadas no horto pertencente ao Laboratório Fitoterápico de Picos (LAFIPI), e analisou o uso de fitoterápicos dispensados pelo Programa Farmácia Viva no triênio 2008-2010. Do total dos 750 entrevistados, 37,6% foram homens e 62,4 % mulheres, dentre os quais a maioria não concluiu o segundo grau (69,2%) e 77,2% possuíam renda mensal de até dois salários mínimos. Com relação ao consumo de plantas medicinais, 76,3% afirmaram utilizá-las para tratar doenças, principalmente por considerá-las mais saudáveis (84,8%). A indicação do uso foi orientada, sobretudo, por familiares (82,2%), embora a maioria adquira as plantas em feiras livres (32,8%). Das 127 plantas relatadas, as mais citadas foram erva-cidreira, boldo e hortelã, sendo as folhas a parte mais utilizada (42,3%), predominantemente por infusão (39,4%). As aplicações mais lembradas foram para tratar dores em geral (17%), distúrbios respiratórios (16,5%) e digestivos (16%). As espécies mais cultivadas no horto são chambá (Justicia pectoralis), alecrim pimenta (Lippia sidoides), malva santa (Plectranthus barbatus) e erva cidreira (Lippia alba). O lambedor de chambá foi o fitoterápico mais procurado pela população entre 2008 e 2010. Esse estudo descreveu, pela primeira vez, o uso tradicional de plantas medicinais no município de Picos e demonstrou, também de forma inédita, a relevância de investimentos do Programa Farmácia Viva no município de Picos e sua inclusão no Programa Saúde da Família como forma de disponibilizar à população de baixa renda fitoterápicos produzidos localmente a custos reduzidos.

Necrotizing fasciitis is a rare and severe infection characterised by extremely rapid progressive involvement of the superficial fascias and deep dermal layers of the skin, with resultant vasculitis and necrosis. The authors present three clinical cases of necrotizing fasciitis; all three patients previously had varicella rash, rapid progressive spreading erythema with severe pain and toxic shock syndrome. Two patients had positive cultures of b-haemolytic streptococcus. Early stage differential diagnosis with celulitis, aggressive antibiotic treatment and pediatric intensive care support are essential. However, the main therapy is early extensive surgical approach involving all indurate areas, down to and including the muscle fascia.

Introduction: Asthma is a chronic inflammatory disease of high prevalence, considered a public health problem and is thought to be one cause of low birth weight and growth retardation., Purpose: The purpose of this article was to review in literature the effects of asthma on the nutritional status in children., Material and Methods: A systematic review was made by searching for articles in PubMed, SciELO and LILACS databases. Review articles, studies with adults or research that did not evaluate the effects of asthma in children were excluded. Hence original articles in humans were included., Results: In the systematic review we found 901 articles in MEDLINE (1966-1996), 47 in LILACS and SciELO in the 16 - Brazil, totaling 964 articles. Of these, 17 articles were selected., Conclusion: Evidence that asthma interferes in nutritional status can not be proven in this study.
