Natural resources with sweetener power: phytochemistry and antioxidant characterisation of Stevia Rebaudiana (Bert.), sensorial and centesimal analyses of lemon cake recipes with S. Rebaudiana incorporation

Stevia rebaudiana leaf extracts are calorie-free sweeteners of natural origin, derived from the Stevia rebaudiana plant known as a natural sweetener, which contains steviol glycosides and others bioactive compounds recognized by their biological properties. The present study was designed to evaluate the total phenolics (26.0 mg gallic acid/g) and total flavonoids contents (9.7 mg catechin/g) of a hydroalcoholic extract of Stevia rebaudiana dried leaves. A similar hydroalcoholic extract of commercial powder steviol sweetener was also evaluated, showing lower contents of bioactive compounds (11.9 mg/g and 5.1 mg/g, for total phenolics and flavonoids, respectively). The hydroalcoholic extract of dried Stevia rebaudiana leaves also showed high in vitro antioxidant activity, besides a positive correlation between total phenolic compounds and the DPPH and FRAP assays. Moreover, Stevia rebaudiana leaves have sensory and functional properties superior to those of many other high-potency sweeteners and is likely to become a major source of natural sweetener for the growing food market. Thus, four different lemon cakes formulations were studied (a traditional cake control recipe with sugar, two cakes with incorporation of Stevia rebaudiana fresh leaf and a cake with commercial powder steviol), using a sensory analysis covering 100 untrained consumers. Centesimal composition analyses of the four lemon cakes showed significant differences in fat, ashes, proteins and carbohydrates contents (p<0.05). Also, the raised energy value observed for the cake control was superior to the cake with Stevia rebaudiana leaves incorporation (309.8 Kcal/100 g, 268.0 Kcal/100 g,142 respectively). Sensorial analysis results showed that Stevia rebaudiana leaves were accepted and, in the future, they can be a natural option to replace some or all the saccharose in cakes formulations.info:eu-repo/semantics/publishedVersio

Prosódia na Libras – um estudo do Corpus do Enem-2017

Facial joints reflect on prosodic subcomponents of oral and sign languages. Therefore, it is a research of an applied, documentary, of a descriptive-exploratory character, through the observational method. The objective is to understand which are the facial movements of intonational prosodic manifestation in Brazilian Sign Language and what it means in a narrative context. As a methodological procedure, we opted for a bibliographic review about American Sign Language (ASL) and Sign Language Israeli and the analysis of a question of the High School National Exam (ENEM) of 2017 – the first edition of the test in Brazilian Sign Language. As results, were created a table about elements of superior facial movements and their means, furthermore verify a relevant contribution to research for the linguistic legitimization of Brazilian Sign Language, for the analyses about teaching and learning sing languages, for the signification, comprehension, and production parlance. Consequently, emphasize a new look and research about the linguistic of Brazilian Sign Languages, due to the scarceness of this publication studies.Las articulaciones faciales reflejan subcomponentes prosódicos del lenguaje oral y de señas. Se trata de una investigación de naturaleza aplicada, documental, de carácter descriptivo-exploratorio, a través del método observacional. Se objetiva comprender cuales son los movimientos faciales de manifestación prosódica de entonación en Lengua Brasileña de Señas y sus significaciones en el contexto narrativo. Como procedimiento metodológico, se optó por una revisión bibliográfica sobre la Lengua Americana de Señas y la Lengua de Señas Israelí, y por el análisis de una pregunta del test del Examen Nacional de la Enseñanza Media (ENEM) de 2017 - primera edición en Lengua Brasileña de Señas. Como resultados, fueron creadas tablas a cerca de los movimientos de los elementos faciales superiores y sus significaciones, verificándose la relevante contribución de la pesquisa para la legitimación lingüística de la Lengua Brasileña de Señas, para estudios sobre la enseñanza y el aprendizaje de las lenguas de señas, para la significación, comprensión y producción del lenguaje. Es evidente, por lo tanto, la necesidad de nuevas miradas e investigaciones acerca de la lingüística de la Lengua Brasileña de Señas, debido a la escasez de estudios publicados.As articulações faciais refletem subcomponentes prosódicos das línguas orais e sinalizadas. Trata-se de uma pesquisa de natureza aplicada, documental, de caráter descritivo-exploratória, através do método observacional. Objetiva-se compreender quais movimentos faciais de manifestação prosódica de entonação na Libras e suas significações em contexto narrativo. Como procedimento metodológico, optou-se por uma revisão bibliográfica sobre a American Sign Language (ASL) e a Língua de Sinais israelense, e pela análise de uma questão da prova do Exame Nacional do Ensino Médio (ENEM) de 2017 – primeira edição em Libras. Como resultados, foram criadas tabelas sobre os movimentos dos elementos faciais superiores e suas significações, verificando-se a relevante contribuição da pesquisa para a legitimação linguística da Libras, para estudos sobre ensino e aprendizagem das línguas de sinais, para a significação, compreensão e produção da linguagem. Evidencia-se, portanto, a necessidade de novos olhares e pesquisas acerca da linguística da Libras, devido à escassez de estudos publicados

Produção de inóculo de estreptomiceto em arroz esterilizado

Os actinomicetos são importantes agentes de controle biológico de doenças e promoção de crescimento de plantas, tornando necessária a obtenção de grandes quantidades de inóculo para trabalhos em casa-de-vegetação e campo. No presente trabalho, avaliou-se o crescimento de diversas espécies de Streptomyces em arroz esterilizado para a produção de inoculo. O arroz foi inoculado com isolados de S. thermotolerans, S. griseus subsp. griseus, Streptomyces sp. N0035, S. purpurascens e Streptomyces sp. e incubado a 28 &plusmn; 2ºC. Cinco dias após a incubação, para todos os isolados de Streptomyces, o crescimento micelial e esporulação eram visíveis nos grãos de arroz. Doze dias após incubação, o arroz colonizado foi transferido para envelopes de papel pardo e colocado em estufa a 30ºC por três dias. Após secagem, adicionou-se 1 g do arroz em 200 mL de água e fez-se a contagem de esporos por grama de arroz, em câmara de Newbauer. A produção de esporos de Streptomyces sp. variou de 0,14 &times; 10(9) a 1,47 &times; 10(9) esporos por grama de arroz e variou entre as espécies de Streptomyces. O arroz esterilizado é um substrato viável para a produção massal, de baixo custo, de inóculo de estreptomicetos.Actinomycetes are important plant disease control and growth promotion agents, which makes it necessary to develop technology to produce large quantities of inoculum for green-house and field work. The present study had the objective of evaluating the growth of several isolates of Streptomyces in sterile rice for inoculum production. The sterile rice was inoculated with isolates of S. thermotolerans, S. griseus subsp. griseus, Streptomyces sp. N0035, S. purpurascens, and Streptomyces sp., and incubated at 28 &plusmn; 2ºC. Five days after its inoculation, mycelial growth and sporulation was observed for all Streptomyces isolates on the rice grains. Twelve days after incubation, the colonized rice was transferred to envelopes of dark brown paper and let to dry in an incubator at 30ºC for three days. After drying, 1g of colonized rice was added to 200 mL of sterile distilled water and the number of spores was counted under a microscope with a Newbauer counting chamber. Spore production varied from 0.14 &times; 10(9) to 1.47 &times; 10(9) spores per gram of rice and differed among the Streptomyces species. Sterile rice can be an alternative substrate for low cost mass production of Streptomyces inoculum

Evaluation of phonological working memory and impulsivity of drugs users treated at an integrated care center for mental health

OBJETIVO: avaliar a memória operacional fonológica e relacionar com a impulsividade de pacientes em tratamento no Centro de Atenção Integrada à Saúde Mental. MÉTODO: 29 usuários: 21 do gênero masculino e 8 do feminino, usuários de substâncias psicoativas, com 37,9±10,5 anos de idade e 10,59±3,53 anos de escolaridade; e 30 voluntários: 19 do gênero masculino e 11 do feminino, com 32,4±11,9 anos de idade e 11,07±3,29 anos de escolaridade, sem histórico psiquiátrico ou de dependência química foram convocados à avaliação de: 1) memória operacional para palavras e pseudo-palavras; 2) impulsividade em seus fatores de segunda ordem (impulsividade atencional, motora e de não planejamento). RESULTADOS: o desempenho dos usuários de substâncias psicoativas na avaliação da memória em comparação ao grupo controle foi pior tanto no span auditivo de palavras e pseudo-palavras como também no número total de recordação de palavras e pseudo-palavras. Na avaliação da impulsividade, os usuários apresentaram escores elevados em contraposição aos sujeitos controle em todos os subtipos de impulsividade, inclusive no total. Na análise de correlação dos dados não foram encontradas relações entre os escores de impulsividade e memória. CONCLUSÃO: : este padrão de respostas indica comprometimento da memória operacional fonológica provavelmente independente do alto nível de impulsividade apresentado pelos usuários de drogas. Estas análises contribuem para propor estratégias de tratamento direcionadas às alterações detectadas.PURPOSE: to evaluate the phonological working memory abilities and check possible influences of impulsivity in patients starting treatment at the program for Alcohol and Drug users at CAISM. METHOD: 29 patients: 21 males and 8 females, drug users, 37.9±10.5 year old and with 10.59±3.53 years of schooling; and 30 volunteers: 19 males and 11 female, 32.4±11.9 year old and 11.07±3.29 years of schooling, with no psychiatric history or substance abuse freely participated. The subjects were asked to attend the specific evaluation, aiming to assess: 1) phonological working memory for words and pseudowords, 2) impulsivity in its second order factors (attention impulsiveness, motor and non-planning). RESULTS: concerning the performance of the subjects in the drug users' group in the evaluation of phonological working memory when compared to the control group we found a reduction in both the auditory word span and pseudowords, as well as the total number of correct recalls of words and pseudowords. In the evaluation of impulsivity, the group of drug users had high scores comparing to control subjects in all subtypes related to impulsivity, including the total score of impulsivity. There were no correlations among impulsivity scores and words and/or pseudowords' span. CONCLUSION: this pattern of responses indicates impairment in verbal working memory processing and high level of impulsivity in this population of chronic drug users. The poor performance of chronic drug users on all tests of phonological working memory is probably not due to the increased noted impulsivity. These analyses help to plan treatment strategies intended towards the detected alterations

Cascading Crypthecodinium cohnii biorefinery: global warming potential and techno-economic assessment

ABSTRACT: Prior to the commissioning of a new industrial biorefinery it is deemed necessary to evaluate if the new project will be beneficial or detrimental to climate change, one of the main drivers for the sustainable development goals (SDG) of the United Nations. In particular, how SDG 7, Clean and Efficient Energy, SDG 3, Good Health and Well Being, SDG 9, Industry Innovation and Infrastructure, and SDG 12, Responsible Production and Consumption, would engage in a new biorefinery design, beneficial to climate change, i.e., fostering SDG 13, Climate Action. This study uses life cycle assessment methodology (LCA) to delve in detail into the Global Warming Impact category, project scenario GHG savings, using a conventional and a dynamic emission flux approach until 2060 (30-year lifetime). Water, heat and electricity circularity are in place by using a water recirculation process and a combined heat and power unit (CHP). A new historical approach to derive low and higher-end commodity prices (chemicals, electricity, heat, jet/maritime fuel, DHA, N-fertilizer) is used for the calculation of the economic indicators: Return of investment (ROI) and inflation-adjusted return (IAR), based upon the consumer price index (CPI). Main conclusions are: supercritical fluid extraction is the hotspot of energy consumption; C. cohnii bio-oil without DHA has higher sulfur concentration than crude oil based jet fuel requiring desulfurization, however the sulfur levels are compatible with maritime fuels; starting its operation in 2030, by 2100 an overall GHG savings of 73% (conventional LCA approach) or 85% (dynamic LCA approach) is projected; economic feasibility for oil productivity and content of 0.14 g/L/h and 27% (w/w) oil content, respectively (of which 31% is DHA), occurs for DHA-cost 100 times higher than reference fish oil based DHA; however future genetic engineering achieving 0.4 g/L/h and 70% (w/w) oil content (of which 31% is DHA), reduces the threshold to 20 times higher cost than reference fish oil based DHA; N-fertilizer, district heating and jet fuel may have similar values then their fossil counterparts.info:eu-repo/semantics/publishedVersio

BATUCADA NO MORRO: A PRESENÇA DA RODA DE SAMBA NO CONTO ANA DAVENGA, DA AUTORA CONCEIÇÃO EVARISTO

This article aims to raise discussions about the presence of the samba circle in the short story Ana Davenga (1995), by Conceição Evaristo, from historical tradition aspects. Initially, the importance of samba is recognized as a form of entertainment for Afro-Brazilian communities, considering the cultural influences from Africa. Thus, support is searched in the theoretical references of Hermano Vianna in the work O Misterio do Samba (1995), Feitiço Decente (2012) by Carlos Sandroni, O Terreiro e a Cidade (2002), by Muniz Sodré, among others. In Ana Davenga short story, the samba circle composes the space of the narrative as the place of fun and joy along with the drumming. Anchored in a literary analysis, this article brought reflective results on the interart relations – literature and music, with emphasis on the legacy left by the peoples in our musical tradition.Este artigo tem como objetivo levantar discussões acerca da presença da roda de samba no conto Ana Davenga (1995), de Conceição Evaristo, a partir dos aspectos da tradição histórica.

Avocado and its by-products: natural sources of nutrients, phytochemical compounds and functional properties

Avocado (Persea americana Mill.) is a tropical and subtropical fruit that is native to Mexico and Central America. This fruit is gaining increasing worldwide acceptance and has received extensive marketing and a wide distribution due to its relevant nutritional benefits for human health. This work presents relevant information on the production, composition and application of avocado, with an emphasis on its by-products, focusing on the proper use of waste and the possibility of monetizing waste for nutritional and environmental purposes. The entire avocado is rich in bioactive compounds (pulp, peel and seed) and presents several health benefits, such as antimicrobial, antioxidant and anticancer activities, as well as dermatological uses and others. Therefore, several food grade ingredients can be obtained from avocado wastes, particularly premium-grade fats or extracts with a high functional power. Studies should continue to identify the profiles and phytochemicals available to the business sector, which can also be implemented to valorize the nutritional and functional potential of avocado seeds and peels.info:eu-repo/semantics/publishedVersio

Educational interventions in relation to the level of physical activities for police officers: a systematic literature review

To systematically review literature in relation to the effects of health education interventions on the level of physical activities for police officers. A systematic review of controlled clinical trials, real-life experiences, quasi-experimental and observational studies investigating the effects of health education interventions in relation to the level of physical activities for police officers. The following electronic data-bases were adopted: Cochrane Central Register of Controlled Trials, PubMed, Biblioteca Virtual em Saúde, Education Resources Information Center and Plataforma Rede Nacional de Atenção Integral à Saúde do Trabalhador. Data collection was carried out in accordance with the main items for systematic reviews. Five articles were selected (N=1302 participants). Improvements to primary and secondary outcomes in the interventions performed in groups or individually, in person and with long-term monitoring, were observed. With reference to the outcomes, educational interventions enabled the improvement, in a statistically significant manner, of the level of physical activities (60% of the studies), reduce body mass index (60% of the studies) and reduce arterial blood pressure (20% of the studies). Educational interventions are capable of improving the level of physical activities, body mass index and arterial blood pressure for police officers

Plano Diretor Participativo do Município de Petrolina e Objetivos de Desenvolvimento Sustentável (ODS): um diálogo necessário para o desenvolvimento territorial sustentável

This paper aims to analyze the Participatory Manager Plan of the Petrolina's Municipality as a local development policy, and its dialogue with the Sustainable Development Goals (SDGs) present in the 2030 Agenda with a view to achieving sustainable territorial development. Through a qualitative bibliographical study and document analysis, it was possible to understand and identify convergences of the themes of sustainable development and territorial development policies, as well as crossings of the SDGs and proposals of the analyzed Manager Plan. It was evidenced that, of the 17 (seventeen) objectives agreed upon in the 2030 Agenda, 13 (thirteen) are included in the drafting of the Master Plan, although, by the analysis of the Sustainable Development Index of Cities - Brazil (IDSC-BR), only 2 (two) were fully achieved. The study revealed that most SDGs are present in the Municipality management planning, but have not been effectively implemented at the municipal level. In this perspective, it will be necessary to deepen this dialogue between the Manager Plan of the Municipality and practical actions for the effective fulfillment of the SDGs with the participation of government, civil society and private initiative.Este trabajo tiene como objetivo analizar el Plan Gestor Participativo del Municipio de Petrolina como política de desarrollo local, y su diálogo con los Objetivos de Desarrollo Sostenible (ODS) presentes en la Agenda 2030 con miras a lograr un desarrollo territorial sostenible. A través de un estudio bibliográfico cualitativo y análisis de documentos, fue posible comprender e identificar convergencias de los temas de desarrollo sostenible y políticas de desarrollo territorial, así como cruces de los ODS y propuestas del Plan Gerente analizado. Se evidenció que, de los 17 (diecisiete) objetivos acordados en la Agenda 2030, 13 (trece) se incluyen en la redacción del Plan Director, aunque, por el análisis del Índice de Desarrollo Sostenible de las Ciudades - Brasil (IDSC-BR), solo 2 (dos) se lograron en su totalidad. El estudio reveló que la mayoría de los ODS están presentes en la planificación de la gestión del Municipio, pero no se han implementado de manera efectiva a nivel municipal. En esta perspectiva, será necesario profundizar este diálogo entre el Plan Director del Municipio y las acciones prácticas para el efectivo cumplimiento de los ODS con la participación del gobierno, la sociedad civil y la iniciativa privada.O presente trabalho tem como objetivo analisar o Plano Diretor Participativo do Município de Petrolina (PE), enquanto política de desenvolvimento local, e seu diálogo com os Objetivos de Desenvolvimento Sustentável (ODS) presentes na Agenda 2030 com vistas ao alcance do desenvolvimento territorial sustentável. Por meio de estudo qualitativo de caráter  bibliográfico e análise documental foi possibilitada a compreensão e identificação de convergências das temáticas de desenvolvimento sustentável e políticas de desenvolvimento territorial, bem como cruzamentos dos OSD e proposições do Plano Diretor analisado. Evidenciou-se que, dos 17 (dezessete) objetivos pactuados na Agenda 2030, 13 (treze) estão contemplados na redação Plano Diretor, embora, pela análise do Índice de Desenvolvimento Sustentável das Cidades - Brasil (IDSC-BR), apenas 2 (dois) foram integralmente atingidos. O estudo revelou que a grande maioria dos ODS estão presentes no planejamento da gestão municipal, mas não foram implementados efetivamente no âmbito do Município. Nessa perspectiva, far-se-á necessário aprofundar esse diálogo entre o Plano Diretor do Município e ações práticas para o efetivo cumprimento dos ODS com participação do governo, sociedade civil e iniciativa privada
