Published: July 2019

RESUMO Eucalyptus benthamii é originário da Austrália, cultivado na região Sul do Brasil, devido à sua tolerância ao clima frio. Durante a produção de mudas dessa espécie vários fatores bióticos e abióticos adversos têm surgido em viveiros. Dessa forma, o presente trabalho teve como objetivo avaliar a podridão de miniestacas de E. benthamii em três clones comerciais, a patogenicidade dos principais fungos encontrados e as principais fontes de inóculo dos fungos causadores dessa doença. As coletas foram realizadas em viveiro clonal de Guarapuava/PR, em setembro de 2016 (1ª coleta) e abril de 2017 (2ª coleta). Coletaram-se miniestacas em fase de enraizamento com sintomas de podridão aparente, brotações sadias, amostras do substrato utilizado para o enraizamento, areia proveniente do minijardim clonal, tubetes, e britas provenientes do piso da estufa. Para detecção e identificação dos fungos, utilizaram-se os métodos de isolamento direto, isolamento indireto, diluição em série, teste com isca de folha de mamona (Ricinus communis) e plaqueamento de resíduos. Botrytis cinerea, Complexo Calonectria scoparia, Fusarium spp. e Pestalotiopsis sp. são os agentes causais da podridão de miniestacas em E. benthamii. Miniestaca assintomática, tubete plástico reutilizado, brita, areia e substrato reutilizado podem ser as principais fontes de inóculo.

ABSTRACT The yerba-mate (Ilex paraguariensis) has great socioeconomic importance on family farming in Southerm Brazil. One of the main yerba-mate disease is root rotting, caused by Fusarium spp. Little is known about the pathogen physiology, especially regarding the aggressiveness associated with the production of extracellular enzymes. On this work, the aggressiveness of isolates of F. oxysporum and F. solani pathogenic to yerba-mate was evaluated and it was determined the activities of extracellular enzymes catalase, laccase, cellulase, caseinase, amylase, protease, lipase and pectinases produced by Fusarium spp. in culture medium. Six isolates of F. solani and one isolate of F. oxysporum pathogenic to yerba-mate were used. The F. oxysporum isolate proved to be less aggressive in relation to the other F. solani isolates. All isolates of Fusarium spp. produced, on a semiquantitative manner, the extracellular enzymes catalase, laccase, cellulase, caseinase, amylase, protease, lipase and pectinases (polygalacturonase and pectate lyase). However, the quantity produced for each enzyme was significantly different among the isolates. With the exception of the laccase and polygalacturonase enzymes, the M7C1 isolate showed the highest enzymatic index and was also responsible for the highest percentage of yerba-mate seedlings death.

Os resultados mostram que considerando apenas os efeitos Constitucionais, a despesa primária teria se mantido estabilizada no período.
Welfare Consequences of Persistent Climate Prediction Errors on Insurance Markets against Natural Hazards
Authors: Guedes Gilvan , Raad Rodrigo , Raad Lucélia
Published: July 2019

Abstract This paper studies the welfare consequences of the friction between two groups, those with and those without rational expectations, in an incomplete insurance market. We validate this friction empirically and test the existence of additional heterogeneity in the probability of belonging to the group which makes persistent mistakes on the anticipation of climate events using econometric models. The econometric models further suggest that the probability of belonging to this group varies significantly by sociodemographic attributes of respondents and by the geophysical attributes of their places of residence. Based on this evidence, we develop a two-period model of private insurance under uncertainty with endogenous prices. By including a central planner providing a technology for access to accurate information, our example illustrates that public intervention (via taxation) would only be feasible if public expenditure in the provision of this technology did not exceed 9.188% of the aggregate income earned by agents with inaccurate expectations.

Authors: Nazareth Marcos Spínola , Gurgel Angelo Costa , Vieira Wilson da Cruz
Published: July 2019

Resumo O propósito central do federalismo é prover uma estrutura estável de descentralização política. No Brasil, ao contrário disso, tem havido recorrentemente períodos de descentralização e centralização fiscal com impactos na performance da economia. A literatura mais recente prevê problemas de incentivos para os governos em ambos os arranjos fiscais. Assim, o objetivo desse artigo foi testar empiricamente a validade da principal proposição do federalismo market-preserving (FMP), qual seja: maior autonomia tributária aos governos regionais disciplinada por imposição de restrição orçamentária rígida e mobilidade de fatores inter-regional, eleva o desempenho econômico. Para isso, foram conduzidos diversos experimentos num modelo de equilíbrio geral computável, que buscaram simular as diferentes intensidades dessas características do FMP. De maneira geral, os resultados confirmam que a economia nacional melhora sua performance (aumentos de PIB e bem-estar), embora em nível regional, em algumas situações, haja aumento das desigualdades.
Dinâmica e Transição da Incerteza no Brasil: uma investigação de autorregressão quantílica
Authors: Souza Michel Cândido de , Zabot Udilmar Carlos , Caetano Sidney Martins
Published: July 2019

Resumo Recentemente, o número de estudos sobre incerteza na economia tem aumentado, em parte, devido às novas técnicas que permitem a construção de proxies adequadas para a incerteza, fundamentalmente não observável, com destaque à técnica de webscrapping, que permite extrair informações online e atualizadas, e que tem sido frequentemente utilizada na construção desses indicadores. Neste contexto, a partir de dois indicadores de incerteza, investiga-se a dinâmica e transição da incerteza no Brasil usando representações autorregressivas quantílicas. Os resultados revelam uma dinâmica assimétrica ao longo de diferentes quantis condicionais, corroborados pela análise de dispersão, amplitude e densidades. Ainda, sugere-se existência de baixa probabilidade, ou até mesmo nula, de migrar-se de um estado de alta incerteza para níveis baixos e vice-versa.
Fatores Associados à Evasão no Ensino Superior Brasileiro: um estudo de análise de sobrevivência para os cursos das áreas de Ciência, Matemática e Computação e de Engenharia, Produção e Construção em instituições públicas e privadas
Authors: Saccaro Alice , França Marco Túlio Aniceto , Jacinto Paulo de Andrade
Published: July 2019

Resumo A escassez de profissionais do campo das ciências naturais e engenharias atinge diversos países. No Brasil, uma das causas para esse fenômeno é a alta evasão de estudantes de cursos de ensino superior dessa área. Em função dos cursos das instituições públicas e de parte significativa dos empréstimos e bolsas de estudo ofertadas no ensino privado serem custeados por recursos governamentais, torna-se importante avaliar os motivos que causam o elevado abandono. Portanto, o objetivo deste artigo consiste em analisar variáveis que influenciam na evasão. O método utilizado é o de Análise de Sobrevivência, por meio das bases de dados do Censo da Educação Superior dos anos de 2009 a 2014. Como resultado, percebe-se que a evasão é maior nas instituições privadas. Ser homem e ter mais idade diminui o tempo de vida do indivíduo no ensino superior, enquanto que alunos contemplados com apoio financeiro apresentam uma maior retenção.
Umbanda e quimbanda: alternativa negra à moral branca
Authors: Carvalho Juliana Barros Brant , Bairrão José Francisco Miguel Henriques
Published: July 2019

Resumo A quimbanda, modalidade de culto afro-brasileiro habitualmente apresentada como mera inversão ético-moral da umbanda, preservou-se em rituais com entidades espirituais que supostamente contestam ou invertem a ordem moral vigente. Neste estudo acompanharam-se esses rituais e coletaram-se depoimentos de sacerdotes em comunidades religiosas afro-brasileiras, com o objetivo de revisar se de fato há uma pressão exercida por padrões ético-religiosos da sociedade envolvente que poderiam ter moderado ou modificado concepções africanas subjacentes. Na contramão de análises que implicitamente pressupõem a subordinação dos cultos afro-brasileiros a uma única concepção de moralidade, constatou-se que a vivência do sagrado implicada na quimbanda e na umbanda não atrela-se a essa moralidade vigente, e que nenhuma das suas manifestações pode ser corretamente descrita como amoral.

Published: July 2019

ABSTRACT: Find shade-tolerant species is essential to the success of silvopastoral systems, increasingly frequent in recent years. In legumes, which have potential of biological nitrogen fixation, there is a great lack of knowledge when in shaded environments.The cultivation of four tropical forage (Neonotonia wightii, Pueraria phaseoloides, Macrotyloma axilare and Arachis pintoi) was evaluated when submitted to artificial shade levels (30, 50 and 70% shade) and in full sun during water and drought seasons. The design used was in randomized complete blocks in a sub-divided plot scheme with four replications. In the Water-season the Forage Peanuts had higher forage production in full sun (11 ton ha-1 DM), and under shade did not differ from Perennial Soybean, higher than the others in all levels of shade. In Drought-season the forage production was 61% lower than in Water-season. The highest crude protein levels were reported in Forage Peanuts, Tropical Kudzu and Perennial Soybean, 19.0; 18.3 and 18.2% respectively in the Water-season. Forage Peanuts is a good option for use in silvopastoral systems although there is a small reduction in forage production (average of 23.7%). In general, species of fabaceae showed a greater reduction in forage production in the period of water deficit; however, shading at levels of 30% to 50% contribute to mitigation of water shortage. Although, there is a small reduction in forage production, withexception of perennial soybeans in dry season, it is advisable to use tropical forage legumes in silvopastoral systems, since forage quality is not affected by shade.

ABSTRACT: In healthy cartilage, chondrocytes maintain an expression of collagens and proteoglycans and are sensitive to growth factors and cytokines that either enhance or reduce type II collagen synthesis. In osteoarthritis, pro-inflammatory cytokines, such as IL-6, induce overexpression of metalloproteinases (MMP) and decreasing synthesis of aggrecan. Use of chondroprotectors agents, such as Platelet-Rich Plasma (PRP) and triamcinolone (TA) are alternatives to reduce the progression of joint damage. In this study, we used chondrocytes extracted from metacarpophalangeal joints of healthy horses as the experimental model. Cells were treated in vitro with PRP or TA. No differences were observed between these treatments in comparison to the control group when the expressions of MMP9, MMP13, IL-6 and ACAN genes were evaluated (P<0.05). With these results, we can suggest that the treatments were not deleterious to equine cultured chondrocyte, once they did not stimulate MMPs and IL-6 synthesis or caused changes in ACAN.

ABSTRACT: Progressive deterioration and loss of articular cartilage are the final degenerative events common to osteoarthritis (OA). Reactive oxygen species (ROS) play an important role in this chondrocyte catabolic activity, leading to cell death and matrix components breakdown. Intra-articular corticosteroid injections such as triamcinolone acetonide have been used to control pain and inflammation associated with OA. New treatments for OA, platelet-rich plasma and pentosan polysulphate sodium have also been used and further investigations are necessary to determine their safety in joint cells. In this in vitro study, the use of these three substances (triamcinolone acetonide, platelet-rich plasma, and pentosan polysulphate sodium) in healthy chondrocytes did not alter the antioxidant status when compared to control groups, indicating that they could be considered safe in healthy conditions.
Family farming in agroecological transition: a look at the marketing of milk and dairy products in municipalities of the Zona da Mata of Minas Gerais State, Brazil
Authors: Santos Priscila Alves dos , Bevilacqua Paula Dias
Published: July 2019

ABSTRACT: This study evaluated the limits and possibilities of the marketing of milk and dairy products in the context of family farming. We used semi-structured interviews, document analysis, and content analysis as methodological options. We conducted 12 interviews with family farmers who had milk production and the processing and marketing of this raw material in common. Despite changes and reformulations, federal and state legislation still does not consider small family farmers. Even when referring to these protagonists, the legislation address production in a technical manner that is inadequate for the reality of most family farmers, thus favouring dairy industries.
Utilization of a novel feedstuff: effects of additives on the fermentation characteristics, chemical composition and in vitro digestibility of tetraploid black locust (Robinia pseudoacacia) silage

Published: July 2019

ABSTRACT: This study was conducted to evaluate the effects of additives on the fermentation characteristics, chemical composition and in vitro digestibility of tetraploid black locust (TBL). The TBL leaves silage was either untreated (control) or treated with 1 × 106 cfu/g FM Lactobacillus plantarum (L), 1% glucose (G), 3% molasses (M), a combination of 1% glucose and Lactobacillus plantarum (L+G), or a combination of 3% molasses and Lactobacillus plantarum (L+M). Fermentation quality, chemical composition and nutrient digestibility were then analyzed. Ethanol and acetic acid concentrations were the dominant fermentation products in all silages except L+M silage. The L, G and L+G treatments failed to influence the fermentation. The M treatment increased (P<0.05) the lactic acid concentration and lowered (P<0.05) the pH when compared with control silage. The best fermentation properties were observed in L+M silage, as indicated by the dominance of lactic acid over ethanol in fermentation products. The M and L+M silages exhibited higher (P<0.05) dry matter, and M silage showed higher residual water-soluble carbohydrates than the control. Ensiling increased (P<0.05) the in vitro dry matter, neutral detergent fiber and acid detergent fiber degradability of TBL. Among the silages, M silage had the highest levels of dry matter, neutral detergent fiber and acid detergent fiber degradability. The obtained results suggested that application of lactic acid bacteria together with 3% molasses could be an effective strategy to prevent the occurrence of ethanol fermentation and improve fermentation quality of TBL silage; addition of fermentable sugars to TBL improves nutrient availability to ruminants.

Published: July 2019

ABSTRACT: Constant monitoring of milk quality by the processing industries demands the use of methodologies that add agility and low-cost analysis, such as the use of electronic equipment based on infrared or ultrasonic spectroscopy. In the present study, quality of raw milk received by dairy farms from western region of Santa Catarina state, Brazil, was evaluated throughout two methodologies of analysis of chemical composition and compared, being that both equipment used standard procedures for calibration, considering as reference data from the classic analytical methods recommended in Brazilian legislation. Milk samples from 45 producers were analyzed for SCC, TBC and physicochemical analysis, performed at dairy’s laboratory and at the official laboratory. Infrared and ultrasound methodologies for chemical composition of fat, protein and lactose were compared and correlated. The comparison of the methods showed that there was no significant difference for the mean values of fat (P=0.06); however, they presented significant difference for protein (P=0.001), higher for IR (3.23 vs. 3.33), and lactose (P<0.0001), higher for US (4.47 vs. 4.83). Correlation was positive and significant for fat (r=0.73, P<0.0001), protein (r=0.47, P=0.001) and lactose (r=0.51, P=0.0003). Considering the minimal composition required, TBC and SCC levels, 95.5%, 84.1% and 64.4% of the milk producers met the current Brazilian legislation, respectively. It was concluded that the methodologies have affected results, which may have been influenced by the correction factor used for equipment calibration, specifically for analyzed samples during the study period.

Published: July 2019

ABSTRACT: The peach palm (Bactris gasipaes) is a palm tree that produces palm heart originated of Amazonia with economic, social and environmental sustainability. To obtain improved cultivars it is necessary the evaluation and selection of genotypes with characteristics that support producers, manufacturing and consumers. In this context, the objective of this study was to estimate genetic parameters for palm heart production traits of peach palm considering half sibs progenies. Twenty progenies of Putumayo macrocarpa race were evaluated in seven cultivation cycles. The experiment was designed in complete randomized blocks, with 40 repetitions and one plant per plot. The genetic parameters were estimated by REML/BLUP methodology. Low genetic variability was observed in the population, possibly due to the narrow genetic base from original population. However, considering the significant genetic effect and the progeny mean heritability, the selection performed between progenies is more efficient than individual selection. The high number of measurements required for most of the evaluated characters becomes impractical in peach palm breeding programs. The number of palm heart per plant can be used to perform indirect selection for total production of palm heart.

Published: July 2019

ABSTRACT: Technique of complex coacervation was used to produce microcapsules of Lactobacillus acidophilus La-5 encapsulated in gelatin and gum arabic which were then freeze-drying. Microcapsules were characterized using scanning electron and optical microscopy, and resistance of probiotics was evaluated during release into a simulated gastrointestinal tract and storage at different temperatures. The complex coacervation process produced microcapsules with a high encapsulation efficiency (77.60% and 87.53%), ranging from 127.14-227.05 μm with uniform distribution. Microencapsulation was an efficient approach to achieve significant protection of probiotics against simulated gastrointestinal conditions compared with free cells. Encapsulation also improved the viability of probiotics during storage at either −18 ºC for 120 days, 7 ºC for 105 days or 25 ºC for 45 days. Therefore, complex coacervation was demonstrated to be adequate and promising for encapsulation of probiotics.

ABSTRACT: The objective of this study was to determine the leaf tissue flows in Italian ryegrass (Lolium multiflorum Lam.), in different phenological stages, grazed by lambs, and managed under three herbage allowances (6, 9 and 12 kg DM/100 kg body weight under rotational stocking method. The experimental design was completely randomized, with repeated measures arrangement. Forage allowances determined similar growth and intake flows, actual and potential utilization efficiencies of grass and they were different in the phenological stages of Italian ryegrass. The intake of leaf blade, as a percentage of body weight, was higher in the 12% herbage allowance. Considering leaf tissue flows, Italian ryegrass can be managed in forage allowances that vary between 6 and 12 kg DM/100 kg body weight.

Published: July 2019

ABSTRACT: Evaluation of fatty acids (FAs) stability in dairy products undergoing technological milk processing is important for subsequent determinations of nutritional value. The aim of the study was to assess FA composition in milk and its dairy product and to explore differences in the FA profile found in yoghurt compared to raw material (goat milk). In the present study, a reduced proportion of volatile FAs (VFA) that cause “goat flavor” was reported in goat yoghurt in comparison to the FA profile of milk. Conversely, an increase of medium-chain as well as beneficial long-chain and unsaturated FAs (UFA) was reported in yoghurt compared with milk. In all cases, the differences in the FA composition between milk and yoghurt were not significant; therefore, it was found that manufacturing of yoghurt had no major influence on FA composition.

Published: July 2019

ABSTRACT: The addition of Cerrado fruits to juice and nectar formulations is an interesting alternative for the beverage industry, as it allows developing innovative products containing nutritive and bioactive compounds. Thus, the objective of this study was to produce mixed nectar of orange and uvaia, using orange nectar as a control, and to evaluate physicochemical and microbiological characteristics of beverages during the storage. Mixed nectar formulations were prepared with the addition of uvaia pulp and orange juice, while the orange nectar was made with fruit juice, and the addition of mineral water and commercial sucrose. Resulting nectar was bottled in sterilized glass bottles, immediately closed and heat-treated in a water bath at 90 °C for 5 minutes. Then, bottles containing the beverages were cooled and stored at room temperature for the physicochemical (Brix, pH, total acidity, ascorbic acid, reducing sugars, and phenolic compounds) and microbiological (total coliforms, molds and yeasts, and lactic acid bacteria) characterization. Total soluble solids and reducing sugars contents increased during storage for the mixed nectar formulations. Higher total acidity and lower pH levels were observed for the mixed nectar throughout the storage. Although, the mixed nectar exhibited higher ascorbic acid content, this parameter was significantly reduced during the storage. Concentration of phenolic compounds was higher for the mixed nectar, which increased with the addition of uvaia pulp to the formulation. Lactic acid bacteria counts remained at reduced levels for all formulations analyzed, while yeasts and total coliforms populations increased in the control formulation during the storage.

Published: July 2019

ABSTRACT: Drying of thin layer tomato was studied using a solar tunnel dryer under the ecological conditions of Isparta, Turkey. During drying process, solar irradiation, drying air temperature, relative humidity, and air velocity were measured constantly in different parts of the dryer. Drying runs were performed using plum tomatoes, characterized by an oval shape, intense red color. The change of tomatoes mass was measured daily. The color measurements of dried products were determined at the beginning and end of experiment. In this study, the fresh tomato samples were sorted, graded, washed in water and then sliced into quarters and halves before pretreated. Sun drying behavior of half and quarter sliced tomatoes pretreated with 10% NaCl solution and non-pretreated was investigated. Results showed that the drying time for pretreated and non-pretreated samples was not significantly different. However, drying time and drying rates were affected by number of tomato slices (quarter and half). Drying characteristic curves were evaluated against thirteen mathematical models and the Midilli et al model was the best descriptive model for solar tunnel drying of thin layer tomato. Color analysis emphasized that if tomatoes are pretreated with 10% NaCl solution, they should be sliced in quarter for better quality.

Published: July 2019

ABSTRACT: The objective of this study was to evaluate, through data simulation, the impact of restrictions on the maximum number of full- and half-sibs selected for males and females on the level of inbreeding and genetic gain of the herd. Data came from real populations A and B, composed of Pietrain and Landrace breed pigs, respectively. To generate the simulated populations, a Fortran-language simulator was developed using the (co)variances of the breeding values and the productive and reproductive rates obtained from populations A and B. Two data files were created. The first contained the pedigree of the previous 10 years, with 21,906 and 251,343 animals in populations A and B, respectively. The second included breeding values for age to reach 110 Kg body weight, backfat thickness, and feed conversion, for both populations; longissimus dorsi muscle depth, for population A only; and number of live piglets at the 5th day of life per farrowing, for population B only. Three scenarios were simulated with ten generations by varying the restrictions on the number of full- and half-sibs selected for males and females, with 30 replicates per generation and scenario. Regardless of the mating strategy used in a closed production unit, there is an increase in inbreeding levels. Inbreeding increases are larger in populations of smaller effective size. Restrictions on the number of full- and half-sibs selected are effective in reducing increments in inbreeding. Restriction to a maximum of two full-sibs and three half-sibs for males and three full sisters for females provided the highest genetic gains.

Published: July 2019

ABSTRACT: We evaluated the influence of temperature on the ability of Salmonella Enteritidis (SE) to form biofilms on stainless steel, polyethylene, and polyurethane surfaces under different hygiene procedures. These materials were placed on SE culture and incubated at 42±1 ºC, 36±1 ºC, 25±1 ºC, 9±1 ºC, and 3±1 ºC for 4, 8, 12, and 24 h. Hot water at 45 ºC and 85 ºC, 0.5% peracetic acid solution, and 1% quaternary ammonia were used for hygienization. Biofilm formation occurred at all temperatures evaluated, highlighting at 3 ºC which has not been reported as an ideal temperature for the adhesion of SE to these materials. The SE adhered more often to polyethylene surfaces than to polyurethane and stainless steel surfaces (P<0.05). Peracetic acid and water at 85 ºC had similar hygienization efficiency (P<0.05) followed by quaternary ammonia whereas water at 45 ºC was not effective. SE adhered to these materials under low temperatures which to date have been deemed safe for food preservation.
Micronization and extrusion processing on the physicochemical properties of dietary fiber
Authors: Bender Ana Betine Beutinger , Goulart Fernanda Rodrigues , Silva Leila Picolli da , Penna Neidi Garcia
Published: July 2019

ABSTRACT: Dietary fiber plays an important physiological role, which is directly linked to its physicochemical properties, water-holding, oil-binding, and cation-exchange capacities. These properties can be altered by employing enzymatic, mechanical, and physical processes. Enzymatic and chemical processes require solvents and special conditions that make it unfeasible to use. Thus, the use of physical methods, such as micronization and extrusion, make promising options to change the physicochemical properties of dietary fiber. In this way, this review aimed to approach relevant information about the use of physical processes, specifically micronization and extrusion, for this purpose. Furthermore, conceptual aspects, such as definition, classification, and properties of dietary fiber and mainly characteristics about the micronization and extrusion processes, are reported. Micronization and extrusion are based on the decrease of the particle size to a micro scale and on the combination of high temperature, mechanical shearing and pressure, respectively. Applying these methods, modifications on the food matrix occurred by increasing the surface area and disruption of the glycosidic bonds. Consequently, there is a change in physicochemical properties of dietary fiber, which predict the physiological effect associated with dietary fiber consumption, such as decrease in blood cholesterol and glucose levels and improvement of intestinal transit. Moreover, these changes increase the bio accessibility of bioactive compounds present in the food matrix and improve the antioxidant capacity of products.

Os moderadores investigados foram saliência de carreira, diferenciação entre interesses ocupacionais e tipos de interesse. Escalas de interesses e ambientes ocupacionais, satisfação intrínseca no trabalho e saliência de carreira foram respondidas por 842 trabalhadores brasileiros. A relação congruência-satisfação foram significativas somente em trabalhadores com baixa saliência de carreira, com elevada diferenciação de interesses e/ou que possuem interesse predominantemente investigativo. Conclui-se que, quanto menor a saliência de carreira do trabalhador e/ou mais diferenciado seu perfil de interesses, mais relevante é a congruência para a satisfação, especialmente em trabalhadores com interesse investigativo. Sugere-se que pessoas com elevada saliência de carreira são capazes de encontrar alternativas de realização profissional mesmo em ambientes de trabalho incongruentes com seus interesses.
