Published: December 2017

Background and aims. To evaluate the staining effects of two brands of coffee and the bleaching efficiency of two in-office bleaching methods, upon different opacities of a commercial nanocomposite.Methods. Twenty four specimens of each opacity, A3 Dentin, A3 Body and A3 Enamel, were fabricated from Filtek Supreme (3MEspe). The specimens were further divided into two groups (n=12) and were immersed in two coffee solutions (Bio Organic Coffee Bellarom, 100% Arabica, and Iulius Meinl Coffee), for 24 hours. Between the staining sessions, the specimens were stored in sterile water, at 37°C. Each group was further divided into three (n=4), in order to be bleached, as follows: Group 1 - Beyond 35% in office, for 4 applications of 15 minutes each, Group 2 – Zoom Day White 6% in office, for 4 applications of 15 minutes each, Group 3 – Control Group, stored in sterile water. Color values were measured with a dental spectrophotometer Vita EasyShade 4.0 and five measurements were recorded for each sample at a time. Lightness L*, color coordinates a* and b* were recorded, at baseline, after staining in coffee and after bleaching. Whiteness index (WID) of the three composite resins (A3D, A3B, A3E) in the three moments were calculated, as well as the color difference Delta E* correspondent to the staining and bleaching process. Data were analyzed using one-way repeated measures ANOVA and the WID index was calculated WID (p<0.05). Univariate analysis of variance was performed for assessing the influence of staining solution upon composite resins, as well as for testing the effect of bleaching agents. The significance level was set at α=0.05 and pairwise comparisons were adjusted by the Least Significant Difference method.Results. The pairwise comparisons showed no significant difference between the effects of the two bleaching agents upon the WID, meaning that they induce almost similar color changes. The results of the univariate ANOVA test indicated a significant effect of the composite resin and the staining solution upon the WID (p<0.05). However, no significant interaction effect was found between the composite resin and the staining solution (p=0.095). There was a significant difference in the staining effect of the two coffee solutions only for A3B and A3E composite resins (p<0.05).Conclusions. The chromatic changes of the nanocomposite resin could be evaluated by the variation of the whiteness index. The staining effect induced by the two types of coffee was similar. The most effective protocol was the in-office bleaching method based on Beyond 35%.

Authors: Guida M. Y. , Hannioui A.
Published: December 2017

In this study, compositional analysis of the products obtained by thermal degradation of sugar cane bagasse at various pyrolysis temperatures (300, 350, 400, 450, 500, 550, 600, 650, 700, 750 and 800 °C) and heating rate (5, 10, 20 and 50 °C/min) was studied. Sugar cane bagasse was pyrolyzed in a stainless steel tubular reactor. The aim of this work was to experimentally investigate how the temperature and heating rate affects liquid and char product yields via pyrolysis and to determine optimal condition to have a better yield of these products. Liquid product (bio-oil) obtained under the most suitable conditions were characterized by elemental analysis, FT-IR, C-NMR and HNMR. In addition, column chromatography was employed to determine the aliphatic fraction (Hexane Eluate); gas chromatography and FT-IR were achieved on aliphatic fractions. For char product (bio-char), the elemental chemical composition and yield of the char were determined. The results of our work showed that the amount of liquid product (bio-oil) from pyrolysis of sugar cane bagasse increases with increasing the final temperature and decreases with increasing the heating rate. The highest yield of liquid product is obtained from the samples at 550 °C and at the heating rate of 5°C/min, the maximal average yield achieved almost 32.80 wt%. The yield of char generally decreases with increasing the temperature, the char yield passes from 39.7 wt% to 21 wt% at the heating rate of 5°C/min and from 32 wt% to 17.2 wt% at the heating rate of 50 °C/min at the same range of temperature (300–800 °C). The analysis of bio-oil showed the presence of an aliphatic character and that it is possible to obtain liquid products similar to petroleum from sugar cane bagasse waste. The solid products (bio-char) obtained in the presence of nitrogen (N2) contain a very important percentage of carbon and high higher heating values (HHV).
Energy efficiency of rotary digesters
Authors: Golub G. A. , Szalay K. , Kukharets S. M. , Marus O. A.
Published: December 2017

In this paper, a new technical solution is introduced for the substrate mixing in a digester. The novelty content lies in the direction changes of the gravitational forces that influence the movement of organic and mineral biomass fractions. Digester case is designed as a horizontal cylinder rotating around a horizontal axis. Digester rotates in water that is in the outer casing.

This design creates a lift force for rotating digester which reduces the load on the bearings. The friction is reduced and therefore it reduces the energy loss of digester rotation and mixing of the substrate.

Published: December 2017

ABSTRACT Objective: Identify the barriers and facilitators of health advocacy to users delivered by nurses from the Family Health Strategy. Method: Qualitative study carried out with nurses from the Family Health Strategy of a city in the south of Brazil. Study participants were 15 nurses, who were interviewed. The content of the interviews was recorded, transcribed and analyzed in the light of the discursive text analysis. Results: Two categories emerged, one about the lack of organization at the workplace, bureaucracy and limitations to professional work in health environments, and another about the facilitating aspects to exercise advocacy both individually and collectively. Conclusion: When nurses, provided with technical, scientific and relational knowledge, are empowered to make decisions, they are not only supported by other professionals at work but also develop actions of health advocacy to users, thus qualifying the care delivered.

Published: December 2017

ABSTRACT The growth of per capita consumption of flowers in Brazil is still low when compared with other countries. Among several factors that may be linked to this growth gap, the establishment of few or ineffective marketing strategies was cited. In this context, we present the results of the profile and behavior of flower consumer, aiming to subsidize marketing actions for the retail segment of flower supply chain. The study was conducted through interviews with 300 people of both genders at the moment they were buying flowers at 22 flower shops in the Paraná coast. This region was selected due to its potential for flower production and commercialization, which is similar to other Brazilian regions and other countries where the flower market has economic relevance. The female gender was identified as the major consumer (n = 62.7%), with tendency of increase in consumption as education level advanced (Spearman correlation coefficient, p < 0.05 = for own use r = 0.122; p = 0.039; for gift r = 0.174; p = 0.003). The acquisition average of 4.4 ± 1.9 times per year was registered, with preferential consumption of orchids (n = 36.3% for own use) and roses (n = 86.7%, for gift). The flower retail trade did not meet the expectations of consumers, especially in relation to price, promotions, and production quality. The male gender and the elderly consumer class may represent important alternatives to increase the current consumption of flowers.

Published: December 2017

RESUMO A ocorrência do oídio (Pseudoidium anacardii) está correlacionada com a brotação nova do cajueiro e à infecção que se processa em botões, flores e maturis jovens. Tecidos maduros tornam-se naturalmente resistentes ao fungo e, para o controle da doença, é necessária a proteção preventiva com fungicida à base de enxofre. Objetivou-se, com este trabalho, avaliar as épocas de floração e os períodos de proteção fenológica do cajueiro-anão BRS 189 à infecção de P. anacardii. O experimento foi realizado em blocos casualizados, com quatro repetições e em esquema de parcelas subdivididas, em que as parcelas foram duas épocas de floração e, as subparcelas, os seis períodos de proteção fenológica. Foram avaliados os graus de severidade do oídio na panícula, no pedúnculo e na castanha e a produção de cajus, durante as duas épocas do fluxo de florações. Verificou-se que as épocas e os períodos de proteção fenológica influenciaram no grau de severidade da doença e na produção de cajus. Para as variáveis de doença, observaram-se menores graus de severidade do oídio para os maiores períodos de proteção fenológica na panícula, no pedúnculo e na castanha. Não houve diferença significativa entre as épocas, quando se avaliaram os períodos de proteção fenológica, em relação ao peso total e pedúnculo, ao passo que, em ambas as épocas, o período de proteção (T6) foi diferente dos demais. Porém, não houve diferença entre épocas e período de proteção fenológica em relação ao peso das castanhas. Os resultados indicam que as épocas do fluxo de florações e os períodos de proteção fenológica interferem na severidade da doença e na produção de cajus do clone BRS 189.

RESUMO O objetivo deste estudo foi caracterizar e avaliar populações híbridas e segregantes, provenientes de cruzamentos entre acessos de Cucurbita moschata, com potencial oleaginoso, e cultivares que apresentam o gene para crescimento do tipo moita (Bush), visando à obtenção de genótipos com elevado teor de óleo nas sementes e com crescimento da planta do tipo moita. O delineamento experimental utilizado foi o de blocos casualizados, com três repetições. Cada repetição foi constituída por cinco plantas dos acessos BGH-7319 e BGH-7765, dos cultivares Piramoita e Tronco Verde e dos híbridos F1 (BGH-7319 x Piramoita, BGH-7319 x Tronco Verde, BGH-7765 x Tronco Verde), sendo consideradas as três plantas centrais das parcelas como úteis. Para cada uma das três populações F2 (‘População 1 F2’, ‘População 2 F2’, ‘População 3 F2’), 30 plantas foram avaliadas. Foram utilizados 28 descritores fenotípicos, sendo nove relativos à fase vegetativa das plantas, 12 referentes aos frutos e sete às sementes. Os dados foram submetidos à análise de variância e as médias dos tratamentos contrastadas com as médias das testemunhas, a 5% de probabilidade, pelo teste Dunnett. Na predição do potencial das populações para obtenção de linhagens superiores, foi utilizada a metodologia de Jinks & Pooni (1976). O híbrido BGH-7319 x Tronco Verde destaca-se para os caracteres massa de sementes por fruto, massa de cem sementes, comprimento, largura e espessura da semente, sendo considerada promissora quanto ao teor de óleo nas sementes. A ‘População 2 F2’ derivada do cruzamento entre os genitores BGH-7319 e Tronco Verde foi considerada a mais promissora para planta com crescimento do tipo moita.

Published: December 2017

RESUMO O gladíolo é uma flor de corte de grande importância nos mercados nacional e mundial. A haste floral, do tipo espiga, é composta por floretes que apresentam abertura acropetal. O conhecimento da velocidade de abertura desses floretes, representada pelo antocrono, pode auxiliar no planejamento das atividades de colheita e comercialização. Os objetivos deste trabalho foram: estimar a temperatura base para abertura de floretes em gladíolo e determinar o antocrono, com a unidade de tempo representada pela soma térmica. Foram conduzidos dois experimentos de campo, em Santa Maria, RS, durante dois anos (2011 a 2013), sendo cada experimento composto por 12 datas de plantio e três cultivares. A soma térmica diária (STd) foi calculada pela diferença entre a temperatura média e a temperatura base (Tb) e, a soma térmica acumulada, pelo somatório das STd. Para a estimativa Tb para abertura de floretes, utilizaram-se os dados do número de floretes abertos (NFA), coletados nos experimentos. Conclui-se que Tb para abertura de floretes em gladíolo é 6 ºC e que o antocrono é, em média, 14,7 ºC dia por florete, mas varia com a disponibilidade de radiação solar durante o florescimento da espiga.

ABSTRACT Knowledge of bud fertility is an important aid in selection of new cultivars of table grapes with high yield potential. The aim of this study was to determine the sprouting percentage and fertility index of buds of 11 cultivars and table grape breeding selections over five production cycles. The study was carried out at the Bebedouro Experimental Field of Embrapa Semiárido in Petrolina-PE, Brazil, in the period 2013-2015 considering 14 table grape genotypes and 5 production cycles as sources of variation. A randomized block experimental design was used, evaluating sprouting percentage and the mean bud fertility index. A significant effect of the genotype on sprouting was observed only in the first and second production cycles; however, bud fertility exhibited significant interaction between the genotype and the production cycle, and the highest mean values of bud fertility were obtained in the fifth cycle in the 2nd semester of 2015. The cultivars ‘A Dona’, ‘A1105’, ‘BRS Clara’, and Marroo Seedless’ stood out through high bud fertility (mean values from 0.78 to 0.95 bunches/shoot) in all the cycles evaluated, with higher values in the terminal buds of the cane (8th and 9th buds). These results show the yield potential of these new cultivars in the São Francisco Valley region.

ABSTRACT The storage of ‘Rocha’ pears under controlled atmosphere (CA) preserves fruit quality for long periods. However, inadequate CA conditions might impair ripening and lead to flesh browning. This research was carried out to assess the effects of CA with ultra-low (ULO), and low O2 (LO) associated with different CO2 levels on ripening and occurrence of flesh browning in ‘Rocha’ pears. Treatments evaluated were: pO2 = 0.5 kPa (ULO) and pCO2 < 0.03 kPa; pO2 = 1.0 kPa (LO) and pCO2 < 0.03 kPa; pO2 = 1.0 kPa and pCO2 = 1.0 kPa; pO2 = 1.0 kPa and pCO2 = 2.0 kPa; and pO2 = 1.0 kPa and pCO2 = 3.0 kPa. A completely randomized experimental design was used, with four replicates. Fruits were harvested in Vacaria, RS, and stored under five CA conditions during 270 days (-0.5±0.1 ºC and relative humidity of 96±2%). Fruits were assessed after CA storage for respiratory rate, ethylene production, skin color, flesh firmness, texture, titratable acidity (TA), soluble solids content (SSC), sensory attributes, flesh browning incidence and severity and flesh color. Fruits stored under LO with pCO2 < 0.03 kPa had higher flesh firmness and more yellow skin color than fruits stored under other CA conditions. Sensory attributes, SS and TA of fruits were not affected by CA conditions. Fruit stored under LO with pCO2 = 3.0 kPa had the highest incidence (48%) and severity of flesh browning. The pO2 = 0.5 kPa and pCO2 < 0.03 kPa and pO2 = 1.0 kPa and pCO2 = 1.0 kPa conditions are the most suitable for the CA storage of ‘Rocha’ pears.

ABSTRACT Peach has great economic and social importance in Brazil. Diverse sources of germplasm were used to introduce desirable traits in the Brazilian peach breeding pool, composed mainly by local selections and accessions selected from populations developed by the national breeding programs, adapted to subtropical climate, with low chill requirement, as well as accessions introduced from several countries. In this research, we used SSR markers, selected by their high level of polymorphism, to access genetic diversity and population structure of a set composed by 204 peach selected genotypes, based on contrasting phenotypes for valuable traits in peach breeding. A total of 80 alleles were obtained, giving an average of eight alleles per locus. In general, the average value of observed heterozygosity (0.46) was lower than the expected heterozygosity (0.63). STRUCTURE analysis assigned 162 accessions splitted into two subpopulations based mainly on their flesh type: melting (96) and non-melting (66) flesh cultivars. The remaining accessions (42) could not be assigned under the 80% membership coefficient criteria. Genetic variability was greater in melting subpopulation compared to non-melting. Additionally, 55% of the alleles present in the breeding varieties were also present in the founder varieties, indicating that founding clones are well represented in current peach cultivars and advanced selections developed. Overall, this study gives a first insight of the peach genetic variability available and evidence for population differentiation (structure) in this peach panel to be exploited and provides the basis for genome-wide association studies.

ABSTRACT Low genetic diversity of citrus scion and rootstock cultivars makes the crop more vulnerable to diseases and pests. The objective of this study was to evaluate the performance of ‘Jaffa’ sweet orange grafted onto five rootstocks over six harvests in subtropical conditions in the north of Paraná state, Brazil. The experiment used a randomized block design, with six replications and two trees per plot, spaced at 7.0 m x 4.0 m. The rootstocks were: ‘Rangpur’ lime, ‘Cleopatra’ and ‘Sunki’ mandarins, ‘Fepagro C-13’ citrange, and ‘Swingle’ citrumelo. The variables evaluated were vigor, yield, and yield efficiency of the trees as well as the physical and chemical characteristics of the fruits. Data were subjected to analysis of variance, complemented by Scott-Knott test at 5% probability. The smallest tree canopy for ‘Jaffa’ sweet orange plants was induced by the ‘Rangpur’ lime rootstock. The trees had the same cumulative yield performance over six seasons for all rootstocks. The best yield efficiency for ‘Jaffa’ sweet orange trees was provided by ‘Fepagro C-13’ citrange rootstock. With regard to fruit quality, no differences were observed among the rootstocks and the ‘Jaffa’ sweet orange fruits met the standards required by the fresh fruit market and the fruit processing industry.

ABSTRACT The blueberry (Vaccinium ashei Reade, Ericaceae) is a small fruit with great growth potential in Brazil. This research was developed in order to identify the insects found on associated to the different phenological stages of blueberry in order to implement the integrated pest management for this crop. Insect samples were collected from three orchards, in the region of Pelotas, RS, from January 2010 to June 2012. The data were analyzed based on the composition and abundance of the collected insects. In all three sites, 2,354 insects were studied and the majority belonged to Hymenoptera (72%), Coleoptera (16%), Hemiptera (6%) and Diptera (4%). Forty-one families were identified with 59% of the listed insects belonging to the Apidae family, followed by 11% for Chrysomelidae and Formicidae. Overall, 50 species of insects were identified and Trigona spinipes (Fabr.) and Apis mellifera L. were the most abundant. Of the species found, 78% were herbivores, while 22% was beneficial insects (pollinators, predators and parasitoids) belonging to the orders Hymenoptera, Coleoptera and Dermaptera. The analysis of variance with the randomization test showed that the insect fauna does not differ between locations and phenological stages. The interaction of site with phenological stages was not significant for the three grade levels (order, family and species). The knowledge of the entomofauna associated with blueberry, along with the similarity in composition with the phenological stages and evaluated sites, contributes to the development of integrated pest management and establishment of production system for this new culture in southern Rio Grande do Sul, Brazil.

ABSTRACT In vineyards, thrips are listed as pests in many countries in continental Europe and the United States, attacking fruits, flowers, leaves and buds. In Brazil, many species have been reported in vineyards. This work aimed to evaluate the best technique and sampling unit, and the number of samples required in a conventional plan for sampling thrips in a vineyard. The studies were carried out in areas of Vitis vinifera, cultivar Sugraone, without application of insecticides. An area of 2.240m2 was subjected to sample collection of leaves in different strata of 15 plants, and leaves on strata of branches for two subsequent years, totalizing 47 sampling dates. Furthermore, the sampling techniques of beating the inflorescence on a tray and whole inflorescence collection were also addressed. To calculate the sampling time, productive vineyards were used, with the varieties Sugraone and Thompson Seedless. Linear regressions of the relative densities as a function of absolute densities for thrips on branch per plant and leaves per branch were estimated. The technique of beating inflorescence on a tray was the one that best represented the results. The sampling unit that best represented the population was composed of one leaf collected from the median part of the branch. Thrips sampling should be conducted in 10 plants and 10 inflorescences per hectare to estimate the thrips population properly on plants and flowers, respectively.

ABSTRACT Over the years, strawberry growth has shown alterations in its phenology, involving mainly the beginning of flowering and fruiting. The aim of this study was to verify whether the growth years influence the duration of strawberry vegetative and reproductive stages in protected environment. The development of the Camarosa strawberry cultivar was observed between 2007 and 2014. The crops were settled in a greenhouse in the Horticulture Sector at the University of Passo Fundo, RS. Data like transplant date, in the beginning and end of the fruits harvest; temperature data (maximum, average and minimum) were recorded in the growth environment. These data were used for the thermal sum calculation (daily, accumulated). The data analyses were carried out in a descriptive manner, relating the temperature data with the phenological stage of each year. The accumulated thermal sum that is necessary to begin the harvest was variable throughout the years, where it was between 383 and 438 degrees days-1 for plants with interval between transplant and harvest of 73 days (2008 and 2009) at 816 degrees days-1, where the interval was 111 days (in 2014). In the first case, it accumulated 5.2 ºC/day, in 2008 and 6 ºC/day, in 2009. In the second case, it was 7.3 ºC/day, in 2014. Seedlings which were transplanted in the first fortnight of May began fruiting in the beginning of August and September. Seedlings transplanted in July 2011 and 2012 began fruiting in similar periods, that is, in the first and second fortnight of September. It was found that, because of the temperatures recorded in different periods of growth and transplant time, there is alteration mainly in the strawberry vegetative stage.

ABSTRACT This study evaluated the post-acidification, stability of anthocyanins and antioxidant activity in açai yogurts and fermented milks for 28 days of cold storage. For the determination of post-acidification and stability of the functional properties of açai yogurt (IA) and fermented milks (LFA), products stored at 4°C were evaluated on day 0 and every 7 days for pH, titratable acidity in lactic acid, instrumental color, anthocyanins and antioxidant activity by the DPPH free radical method. Acidification of both food matrixes was more evident between days 0 and 7 of evaluation. IA presented reduction in parameter L *, while chromaticity a * and b * of IA and LFA increased as the Açai pulp content increased; however, considering the evaluation period, it was found increase in L * and b * relating to anthocyanin degradation. Anthocyanins, as well as the antioxidant activity of IA and LFA, showed an increase in their values as the pulp content increased, but their concentrations reduced at the end of the storage period. IA and LFA can be considered excellent sources of antioxidants, being alternative to individuals not used to the consumption of fruits and vegetables.
Resignação? Práxis e política na teoria crítica tardia de Theodor W.
Authors: Fleck Amaro
Published: December 2017

Resumo A teoria crítica tardia de Theodor W. Adorno é considerada por muitos como quietista e resignada. O presente artigo busca questionar tal veredito por meio de uma análise tanto do diagnóstico de época, feito pelo autor, quanto da relação entre teoria e práxis delineada nas obras do período tardio do pensador frankfurtiano. Sugere-se que, em vez de resignada, a teoria crítica de Adorno está engajada seja nos processos de resistência à barbárie latente, seja nas melhorias pontuais que poderiam ser conseguidas no interior da ordem vigente. Tal engajamento, no entanto, não significa um abrandamento da tese de que a possibilidade de emancipação estaria bloqueada.
O PROJETO HEGELIANO DE UMA FILOSOFIA LIVRE DE PRESSUPOSIÇÕES
Authors: Orsini Federico
Published: December 2017

Resumo O objetivo de meu trabalho é o esclarecimento de quatro características distintivas do sistema hegeliano como projeto de uma filosofia livre de pressuposições. Para tanto, pretendo reconstruir a conexão entre os seguintes traços constitutivos do conceito operativo de Voraussetzungslosigkeit (ausência de pressuposição): em primeiro lugar, a imanência do real ao pensar objetivo; em segundo, a integração do ceticismo pirrônico ou antigo ao modo de apresentação científica do pensar; em terceiro lugar, a configuração do elemento lógico em termos de um movimento de circulação de si mesmo; em quarto, a subversão da compreensão ordinária da dupla conceitual "abstrato-concreto". A reconstrução assim oferecida permite argumentar sobre conclusões relevantes para compreender adequadamente a ambição do projeto especulativo de Hegel: em primeiro lugar, a ausência de pressuposições só pode confirmar-se enquanto prova científica por meio da subversão das certezas arraigadas no senso comum; em segundo, a prova da imanência é científica na medida em que mostra o necessário entrelaçamento do aspecto ontológico com o aspecto epistemológico do sistema, tornando-o invulnerável a objeções céticas de tipo radical; em terceiro, o sistema não é de modo algum reduzível à estrutura da Enciclopédia, pois essa é apenas um auxílio didático para a apresentação do sistema, cujo significado verdadeiro pode ser atingido unicamente pela organização cada vez mais concreta dos silogismos da ideia da filosofia.
La matrice juridique et révolutionnaire de la pensée kantienne
Authors: Garcia Luís Fellipe
Published: December 2017

Résumé L’article vise à souligner la signification politique de l’avènement de la Critique kantienne. Pour ce faire, une double thèse est défendue : (I) il y a une matrice juridique sous-jacente au mouvement conceptuel de la philosophie critique, dont (II) la puissance émancipatrice et révolutionnaire se manifeste à la lumière du contexte historique de sa formulation. L’argument se déploie de la façon suivante : (i) une exploration des rapports entre la formule « révolution de la pensée » que l’on trouve dans la Critique de la raison pure et le contexte historique de la publication l’œuvre ; ensuite (ii) un examen de la métaphore juridique et la façon dont elle incarne l’idée d’une philosophie critique ; et pour conclure (iii) la suggestion d’une hypothèse interprétative d’après laquelle le « contrat originaire » est un opérateur conceptuel accomplissant un mouvement analogue à celui qui est exigé de la philosophie critique : le passage du niveau individuel au niveau intersubjectif.

Resumo: Desde 2009, legislação do Programa Nacional de Alimentação Escolar do Brasil (PNAE) institucionaliza a sua vinculação com a agricultura familiar ao estabelecer a obrigatoriedade de que, pelo menos, 30% do total dos recursos financeiros repassados pelo governo federal aos estados e municípios para a alimentação escolar devem ser utilizados na compra de produtos diretamente desse setor. Este estudo analisa o processo de construção desta legislação mediante contextualização histórica, focando nos elementos relacionados à compra da agricultura familiar e, também, apresenta uma representação gráfica com os principais elementos da vinculação: objetivos, público-alvo, ações implementadas e resultados esperados. Foram entrevistados atores envolvidos na construção da legislação. As análises evidenciam que a compra da agricultura familiar pelo PNAE é uma iniciativa de amplo alcance, do ponto de vista conceitual, de execução e de resultados. Também se evidenciou que, para o seu êxito, é fundamental uma ampla articulação entre os atores e órgãos dos vários setores envolvidos, assim como múltiplas estratégias implementadas pelas distintas esferas de governo. Dessa maneira, setores da educação, agricultura, planejamento, compras e sociedade civil devem articular-se em nível nacional, estadual e local. Os resultados deste estudo demonstram que iniciativas como essas, de compras institucionais da agricultura familiar, que estão sendo implantadas atualmente em vários países, configuram-se como importante estratégia de segurança alimentar e nutricional, de cumprimento do direito humano à alimentação adequada e de promoção do desenvolvimento sustentável a longo prazo.
O tempo de percurso a cidades polos regionais influencia na mortalidade em pequenos municípios gaúchos?
Authors: Zuanazzi Pedro Tonon , Cabral Pedro Henrique Vargas , Stella Milton André , Moraes Gustavo Inácio de
Published: December 2017

Resumo: O presente estudo objetiva responder se o tempo de viagem a municípios polos regionais possui efeito na taxa de óbitos por causas evitáveis (TOCE) e na taxa bruta de mortalidade padronizada (TBMP) em municípios com até 5 mil habitantes do Rio Grande do Sul, Brasil. Sem a utilização de variáveis controles, o maior tempo de percurso até municípios com 100 mil habitantes ou mais está associado com um aumento de ambas as taxas. No entanto, enquanto que o comportamento da TOCE permanece similar após a inserção dos controles, a TBMP inverte seu sinal, sugerindo que, mantendo as demais características socioeconômicas e de atendimento de saúde constantes, a distância a municípios polos está associada, ao mesmo tempo, a uma redução dos óbitos por causas evitáveis e a um aumento nas demais causas de morte.

Resumo O comportamento espacial e temporal do saldo de radiação (Rn) à superfície terrestre tem sido tema de estudos sobre os ecossistemas de regiões semiáridas do globo e poucos estudos têm sido destinados à região semiárida do Brasil, especificamente no ecossistema de Caatinga. Logo, o objetivo deste estudo foi utilizar uma metodologia que não necessite diretamente de dados de superfície para estimar o Rn na região semiárida da Paraíba, a partir de dados orbitais do sensor MODIS, e validar com dados medidos em áreas experimentais de Caatinga em recuperação e degradada. Diante dos resultados encontrados, pode-se constatar a eficácia da metodologia proposta, sendo a mesma mais precisa em áreas com o solo mais descoberto. De acordo com a análise estatística, a metodologia apresentou uma melhor qualidade do ajuste para a área em recuperação, com a variação explicada de 78% e para a área degradada de 61%.

Resumo O estudo avaliou a ocorrência de focos de calor nos remanescentes da Mata Atlântica no estado do Rio de Janeiro, sob o aspecto climático. As informações obtidas da base de dados BDQueimadas, do período de junho de 1998 a dezembro de 2015, sofreram estatística descritiva, exploratória e paramétrica. As maiores ocorrências de focos de calor foram registradas nos meses de agosto, setembro e outubro e, os anos com os maiores registros foram nos ciclos 2010/2011 (16,06%) e 2014/2015 (41, 24%), ambos somaram 57,30% da série temporal, referente a La Niña e El Niño nas categorias forte e fraco. O teste paramétrico mostrou uma repetição dos meses de abril e junho nos anos avaliados na série temporal de focos de calor. As regiões de Governo Centro-Sul Fluminense e Médio Paraíba registraram os maiores registros de focos de calor, segundo a avaliação espacial. Nossos resultados demonstram que o acesso a uma base gratuita de dados permite a prevenção de danos causados pelas queimadas e incêndios. Com a evolução dos sensores de temperatura e de algoritmos de tratamento de dados, será possível diferenciar os focos de calor que representam incêndios e queimadas daqueles que indicam, por exemplo, atividade de indústrias.

Abstract The aim of this study was to synthesize and evaluate physicochemical properties of a new salicylate derivative in experimental calcium-based root canal sealers. Two salicylate derivatives were synthesized for the transesterification reaction of methyl salicylate with two different alcohols (1,3-butylenoglicol disalicylate-BD and pentaerythritol tetrasalicylate -PT) in molar ratio 1:3 and 1:6, respectively. The products (BD and PT), were characterized by Fourier Transform Infrared Spectroscopy (FTIR) and Nuclear Magnetic Resonance spectroscopy (RMN). Calcium-based experimental sealers were prepared with the same catalyst paste (60% of MTA, 39% of n-ethyl-o-toluenesulfonamide, and 1% titanium dioxide) and four different concentrations of BD and PT in the base pastes (40/0 - control, 35/5, 30/10 and 20/20) with 60% of bismuth oxide. The experimental sealers were evaluated for setting time, solubility (24 h, 7, 14 and 30 days), diametral tensile strength and Young’s Modulus. Data were analyzed by one- or two-way ANOVA with Tukey’s test (p<0.05). The addition of PT reduced the materials setting time. After 24 h the sealer 40/0 and 35/5 had higher solubility, and after 14 and 28 days the sealer 20/20 showed the lowest solubility (p<0.05). After 7 days the sealer 20/20 stabilized its solubility. The sealer 40/0 presented the highest values and the 20/20 presented the lowest values of diametral tensile strength and Young’s modulus (p<0.05). The addition of PT to calcium-based root canal sealers provides benefits to the setting time and solubility.

Abstract The purpose of this study was to evaluate different retention systems (cement- or screw-retained) and crown designs (non-splinted or splinted) of fixed implant-supported restorations, in terms of stress distributions in implants/components and bone tissue, by 3-dimensional (3D) finite element analysis. Four 3D models were simulated with the InVesalius, Rhinoceros 3D, and SolidWorks programs. Models were made of type III bone from the posterior maxillary area. Models included three 4.0-mm-diameter Morse taper (MT) implants with different lengths, which supported metal-ceramic crowns. Models were processed by the Femap and NeiNastran programs, using an axial force of 400 N and oblique force of 200 N. Results were visualized as the von Mises stress and maximum principal stress (σmax). Under axial loading, there was no difference in the distribution of stress in implants/components between retention systems and splinted crowns; however, in oblique loading, cemented prostheses showed better stress distribution than screwed prostheses, whereas splinted crowns tended to reduce stress in the implant of the first molar. In the bone tissue cemented prostheses showed better stress distribution in bone tissue than screwed prostheses under axial and oblique loading. The splinted design only had an effect in the screwed prosthesis, with no influence in the cemented prosthesis. Cemented prostheses on MT implants showed more favorable stress distributions in implants/components and bone tissue. Splinting was favorable for stress distribution only for screwed prostheses under oblique loading.

Published: December 2017

Abstract The aim of this systematic review and meta-analysis was to compare the peri-implant vertical bone loss of immediate loading of implant crowns using the one abutment at one time (AOT) protocol and implants with abutment removal (AR). This systematic review with meta-analysis was reported according to the PRISMA statement, with guidance from the Cochrane Collaboration Handbook. A total of 103 publications were identified in the PubMed database and reference lists of examined articles. After the screening of titles and abstracts, the eligibility of eight full-text articles was assessed. Five studies published between 2010 and 2015 were included in the meta-analysis. There was less peri-implant vertical bone loss at implants using an AOT protocol than at implants using AR protocol (WMD -0.19, 95% CI -0.26 to -0.13; p<0.0001; random-effects model). In conclusion, the use of the AOT protocol with platform-switched Morse implants results in less bone loss than do AR procedures, but this effect may not be clinically relevant. The preservation of marginal bone level achieved with the AOT protocol may not enhance the aesthetics. These results should be interpreted with caution.
