Food Proteins: Sustainable Sources of Proteins Responsible for Emulsions Stability in Food Products

One of the major challenges manufactures are facing is the fact that consumer’s personal health standards are changing constantly, modern consumers are willing to know more about the ingredients used in their food. The relationship with ethics and sustainability is leading to changes in the food industry. Seen this, manufactures are opting for other sources of ingredients, such as plant-based alternatives. However, the use of these sort of products need to be developed due to of their unknown properties. The use of sustainable plant proteins provides a variety of benefits to the product, such as added nutritional value as fiber, proteins and antioxidants, emulsion formation, product stability and extended shelf-life. There is a wide variety of plant-based proteins used in the food industry. The most common protein from animal origin used in the food industry are whey protein (Concentrate/Isolate) and casein, egg protein and egg lecithin which provide a strong emulsion thickness. Sustainable plant based proteins are being widely used, such as pea protein, tea saponin, potato protein, soy beans and microalgae and they provide similar or even better emulsion stability and nutritional benefits. This research was conducted with 281 people, the aim is to identify behaviours, knowledge, attitudes, preferences, and awareness levels associated with sustainable sources of plant-based proteins used as ingredient in the food industry versus animal origin proteins of people living in Ireland. The findings identified that consumers are demanding for more accurate information on product ingredients description and benefits, the food industry is developing new methods for the better usage of plant-based proteins and improvement of their natural properties, providing improved sensory, physical and nutritional properties to the final product. This study observed that consumers are not fully aware of plant-based proteins used as product ingredient, neither are aware of their nutritional benefits. The sensory test exposed that consumers showed to still prefer whey protein sensory characteristics, when compared to plant-based proteins. The majority confirmed to be aware of the relationship of the use of more sustainable sources of food proteins and the development of a fully sustainable food chain and with the future health of the planet. Moreover, we can relate these facts with consumers’ willingness to pay a small increase of value for a sustainable food product, in contradiction, when considering purchase attributes, sustainability was the last considered, the firstly considered were nutrition and cost. The results from this study highlight the need for more research in this area, with the aspiration to enforce the usage of more plant-based proteins as product ingredient, improving nutrition and emulsification properties

O desenvolvimento do estágio curricular no curso de administração: caso do programa de consultoria acadêmica do Uniceub/DF

O referido artigo discorre de um estudo de caso do modelo de estagio curricular adotado no curso de administração do Centro Universitário de Brasília- UniCeub. Denominado como Programa de Consultoria Acadêmica (CONSAC) o estagio em formato interno tem a função de aliar consultoria, estagio e aprendizado. O projeto consiste em oferecer às empresas no Distrito Federal, consultoria especializada em gestão empresarial. A experiência possibilita um aprendizado e aplicação dos insumos teóricos trabalhados ao longo do curso aos problemas das organizações clientes com vistas a identificar possibilidades de melhoria e sugerir planos de ação para as empresas clientes e aos alunos, a formação nos conhecimentos teóricos e práticos voltados a sua profissão. O levantamento dos dados deu-se através de observação assistemática ao longo dos dois primeiros anos de implementação do projeto. Além disso, foram mensuradas a percepção dos alunos e empresas clientes sobre o programa e o serviço prestado através de questionários. Observa-se que o modelo cumpre os objetivos iniciais e que adesão e aceitação dos alunos e empresários é positiva, reforçando a estrutura de funcionamento e as estratégias metodológicas adotadas

The Dirichlet Casimir effect for ϕ4\phi^4 theory in (3+1) dimensions: A new renormalization approach

We calculate the next to the leading order Casimir effect for a real scalar field, within $\phi^4$ theory, confined between two parallel plates in three spatial dimensions with the Dirichlet boundary condition. In this paper we introduce a systematic perturbation expansion in which the counterterms automatically turn out to be consistent with the boundary conditions. This will inevitably lead to nontrivial position dependence for physical quantities, as a manifestation of the breaking of the translational invariance. This is in contrast to the usual usage of the counterterms in problems with nontrivial boundary conditions, which are either completely derived from the free cases or at most supplemented with the addition of counterterms only at the boundaries. Our results for the massive and massless cases are different from those reported elsewhere. Secondly, and probably less importantly, we use a supplementary renormalization procedure, which makes the usage of any analytic continuation techniques unnecessary.Comment: JHEP3 format,20 pages, 2 figures, to appear in JHE

Estudo da viabilidade na utilização de resíduos de construção e demolição (rcd) para produção de argamassa e concreto não estrutural no Distrito Federal - Brasília

A busca por alternativas que visam a redução dos impactos ambientais causados pelo descarte inadequado dos resíduos de construção e demolição vem ganhando maior destaque dentro das empresas e instituições acadêmicas ligadas à construção civil. Uma das alternativas estudadas, trata-se do uso do agregado reciclado na produção de argamassa e concreto. Buscando avaliar a utilização de resíduos de construção e demolição como agregado reciclado, a presente pesquisa teve como objetivo analisar o comportamento físico e mecânico do concreto não estrutural e da argamassa produzidos com agregados reciclados. Para argamassa foram desenvolvidos 2 traços: traço de referência (sem substituição) e traço com 100% de substituição do agregado miúdo por agregado reciclado. Para o concreto não estrutural foram desenvolvidos 3 traços: traço de referência (sem substituição); com 100% de substituição do agregado miúdo por material reciclado e com substituição de 100% de agregado miúdo e agregado graúdo por material reciclado. Foram moldados 12 corpos de provas cilíndricos, com 100 mm de diâmetro e 200 mm de altura, para todos os traços de concreto e 9 corpos de prova prismáticos, para cada um dos traços de argamassa. A partir da revisão da literatura e dos ensaios laboratoriais, foram realizados os ensaios de: caracterização dos materiais; do concreto: desempenho mecânico (resistências à compressão, à tração por compressão diametral); Desempenho físico (consistência de abatimento do tronco cônico - slump test e absorção de água por imersão, índice de vazios e massa específica); e da argamassa: desempenho mecânico (resistências à compressão e à tração na flexão); desempenho físico (índice de consistência, densidade de massa e teor de ar incorporado) seguindo todas as normas vigentes. Diante dos resultados alcançados, o concreto confeccionado com substituição total dos agregados naturais por agregados reciclados, apresentou resultados satisfatórios, destacando-se para a resistência a compressão, 27% maior que a obtida pelo concreto referência. Entre as argamassas, a confeccionada com agregado miúdo reciclado, obteve uma resistência a compressão, na idade de 28 dias, 20,3 % maior em comparação a argamassa confeccionada com agregado miúdo natural

Effectiveness of Public Health Interventions in Reducing Morbidity and Mortality during Heat Episodes: a Structured Review

Increasing concern over the impact of hot weather on health has fostered the development of public health interventions to reduce heat-related health impacts. However, evidence of the effectiveness of such interventions is rarely cited for justification. Our objective was to review peer-reviewed and grey literature evaluating interventions aimed at reducing morbidity and/or mortality in populations during hot weather episodes. Among studies considering public risk perceptions, most respondents were aware when an extreme heat episode was occurring but did not necessarily change their practices, primarily due to a lack of self-perception as vulnerable and confusion about the appropriate actions to be taken. Among studies of health outcomes during and following heat episodes, studies were suggestive of positive impacts in reducing morbidity and mortality. While the limited evaluative work to date suggests a positive impact of public health interventions, concern persists about whether the most vulnerable groups, like the elderly and homeless, are being adequately reached
