O produtor rural deve se adequar, na tentativa de tornar-se consciente da gestão de sua propriedade rural, pois um melhor gerenciamento resulta em maior lucratividade e em menor custo de produção. Sendo assim, o objetivo deste trabalho foi realizar um diagnóstico do uso de ferramentas de gestão por produtores rurais do município de Uberlândia – MG. Para tanto, realizou-se a aplicação de formulários estruturados a 23 produtores rurais da referida localidade, através de pesquisa de campo, obtendo-se assim, panoramas quanto ao uso destas ferramentas. Os resultados indicam a necessidade de aprimoramento e do uso das ferramentas de gestão utilizada pelos proprietários rurais entrevistados. Detectou-se, ainda, a necessidade de abertura de um curso para esclarecimento do uso dessas ferramentas.
This article investigates the relationship between the water-energy-food (WEF) nexus in Brazil in an exploratory and statistical study over the period from 2000 to 2013. For that purpose, the explanatory variables considered were the following: Access to improved water; Access to electricity and Average protein supply. Furthermore, some brief facts about WEF nexus security in Brazil was introduced. With such explanatory variables, descriptive statistics was performed, ensuring the assumption of data normality approach, and consequently calculating the descriptive statistics and correlation. The results of correlation showed that the quantitative relation between the three factors was extremely strong. These data allowed to understand the relation between these indicators and its status as a nexus in Brazil. Therefore, it is concluded that pursuing an active policy to manage demand in WEF nexus could lead sustainability processes.
A utilização de suplementos alimentares tem-se tornado cada vez mais popular entre praticantes de atividades físicas, entretanto, o uso inadequado e sem orientação pode acarretar em problemas de saúde. Neste contexto, o objetivo deste estudo foi verificar o uso de suplementos nutricionais por adolescentes, alunos do IFTM Uberlândia praticantes de atividade física. Para tanto, confeccionou-se questionário semiestruturado e após préteste realizado aplicou-se a 50 jovens, de ambos os sexos, de modo não probabilístico por conveniência. Os resultados foram tabulados utilizando estatística descritiva com o apoio do software excell. Os resultados obtidos indicam que 20% dos entrevistados utilizam ou já utilizaram suplementos proteicos, e 14% tem um acompanhamento regular com o nutricionista. O Whey Protein se destacou como o suplemento nutricional mais consumido entre a população em estudo. Pode-se concluir que a prevalência do uso de suplementos alimentares é relativamente significativa e confirma que há necessidade de mais informações e estudos sobre as consequências da utilização desinformada dos suplementos alimentares.
The water–energy–food (WEF) nexus approach is gaining attention due to the challenge of better managing natural elements. Agro-industrial companies, given their environmental impacts, need to take sustainability into proper account. However, this sector lacks the novel tools needed to integrate current methodologies with additional quality frameworks, such as business excellence models (BEMs). Therefore, the present research aims to propose a sustainability-focused excellence model by integrating the principles and objectives of the WEF nexus with existing BEM and proposing its application to agro-industrial companies. For that purpose, a new conceptual model to integrate sustainability and excellence was built. The proposed novel model can become a decision-support tool in helping agro-industrial companies transition toward improved sustainability while managing existing tradeoffs and synergies.
Arthrospira platensis is a rich source of essential amino acids, vitamins and it is used as a feedstock for energy sources. The high cost of the growth medium used in its cultivation is a problem for increasing the production viability. The present study aimed to compare the technical viability and the cost elementsin different growth medium for A. platensis cultivation. For that purpose, it was proposed the use of three different growth medium, named as M1, M2 and M3 in a lab scale. The growth of the treatments presented a microbial process with characteristic phases. M1, M2 and M3 maximum concentration (Xmax), productivity (Px) and the maximum specific growth rate (μmax) showed no significant difference among treatments. However, M3 presented the lowest cost element, about 45.75% less than the M1 and 38.92% lower than M2. Therefore, the comparison enabled the result that M3 presented the best performance to be used, thus increasing profitability of this production in a lab-scale analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
