title: Soil cover management: initial development of pear trees hosui cultivar and its effects on soil and weeds

description: Abstract Soil management is a practice that influences the development of fruit trees. In this sense, the objective of this study was to evaluate the effect of different soil cover/mulching types on weed control and on the early development of pear trees Hosui cultvar. The experiment was conducted in two consecutive cycles: 2015/2016 and 2016/2017. Treatments consisted of the following soil covers in pear tree planting rows: natural cover, ryegrass straw intercropped with millet, pine sawdust, shading cover (70%), rice husk, Curauá fiber and weeding. Soil infestation by weeds was evaluated in the spring-summer period for two years, as well as the vegetative pear tree development (plant height and diameter and SPAD chlorophyll index). Managements using Curauá fiber and ryegrass straw + millet had the greatest suppression effects on weeds. The height and diameter of pear trees were smaller with natural cover and pine sawdust, while higher plant growth was observed with Curauá fiber and with weeding. Higher SPAD indexes was observed with Curauá fiber, weeding and ryegrass + millet. Curauá fiber also stood out for Fe and Mn leaf contents, while Zn contents were higher with ryegrass + millet and rice husk. Ryegrass straw + millet and rice husk can be highlighted for the chemical attributes of soil fertility and soil macrofauna indexes. It could be concluded that Curauá fiber and azevem + millet weed control weeds in the orchard, thus promoting better initial development of pear trees Hosui cultivar.

title: Capacity of government in Municipal Health Departments

description: ABSTRACT From the decentralization of Unified Health System (SUS) management, there is a need to discuss the capacity of government, or management, at the municipal level, to implement this policy. This study aims to analyze the capacity of government of Municipal Health Departments in municipalities of Bahia, based on the experience of managers. An online questionnaire, subdivided into 03 dimensions, was applied to 15 managers representing municipal departments of small size (size I) and large size (size II) in the 09 macro regions of health of the state. A punctuation matrix was used, which allowed the quantification and classification of municipalities in each of the dimensions and their capacity to govern. It was obtained that 12 of the municipalities presented moderate, and 03 presented low capacity of government. The dimension related to the organizational design of the Secretariats was the one in which the municipalities presented better performance, followed by work systems in these organizations and professional trajectory of managers. Still, municipalities of size I and those located in more developed regions obtained better overall results. To qualify the managements, it is considered essential to invest in training initiatives and institutional support, prioritizing small size municipalities and located in regions of greater socio-economic vulnerability.

title: First report of Myxobolus (Cnidaria: Myxozoa) spores in human feces in Brazil

description: ABSTRACT Most species of Myxobolus (Cnidaria: Myxozoa) infect freshwater and marine fish, and cause sporozoosis. Passage of myxozoan parasites into human feces has been described occasionally. We examined fecal samples from 97 dwellers of a riverine community in Amazonas State (Brazil), which revealed Myxobolus sp. in 13 (13%) samples. The discovery probably does not represent true parasitism as the myxospores - most likely ingested through the consumption of infected fish - were eliminated unchanged after passing through the gastrointestinal tract. This discovery represents the first report of this myxosporean in human fecal samples in Brazil.

title: Physical characterization of Arabica ground coffee with different roasting degrees

description: Abstract: Roasting is a determinative operation on the final quality of coffee. Roasting process causes physical, chemical and sensory changes on coffee. In this study roasting degree effect on physical properties of Arabica fine ground coffee was examined. The bulk properties, particle property, reconstitution properties, moisture content, water activities and color properties were investigated in different roasting degrees of coffee. The results showed that the physical characteristics of coffee samples were influenced by the degree of roast. To have longer shelf life, lower cost and better physical attributes of Arabica fine ground coffee, the roasting process should be kept at a lower degree. At the same time the requests and expectations of customer should also be considered.

title: Molecular characterization of virulence genes cctA, nanA, and fliC in Clostridium chauvoei from Rio Grande do Sul and São Paulo State, Brazil

description: ABSTRACT: Clostridium chauvoei toxin A (CctA), neuraminidase (NanA), and flagellin (FliC) proteins contribute to the pathogenicity of Clostridium chauvoei, the causative agent of blackleg in cattle. The aim of this study was to analyze the genetic variability of cctA, nanA, and fliC genes in C. chauvoei isolates from the Rio Grande do Sul and São Paulo state- Brazil, during different sampling periods. The presence of these genes was verified through PCR amplification and partial gene sequencing of 17 strains. Alignment of PCR amplicons combined with bioinformatics analysis was used in an attempt to study the variability across C. chauvoei solates. The similarity among the partial sequences of cctA and nanA genes was 100%. The sequencing of fliC revealed three different paralog alleles of flagellin, and two strains were seen to be polymorphic, with amino acid alterations in the predicted protein. Overall, this study indicates that strains of C. chauvoei isolated in Brazil are highly conserved with respect to the virulence factors evaluated.

title: Genetic diversity, population structure and AFLP markers associated with maize reaction to southern rust

description: ABSTRACT Maize is one of the species with greater genetic diversity among cereals and possibly the most diverse crop species known. Accessing this variability is essential for maize breeding, allowing breeders to achieve progress of yield increasing, overcome environmental challenges or deal with pests and diseases. Among the maize diseases, southern rust is one of the most important, causing significant losses in yield and presenting severe epidemics worldwide. In the present study, the AFLP technique was applied to analyze population structure and genetic diversity among 145 tropical maize inbred lines, and to test for preliminary evidence of association between AFLP markers and the reaction to southern rust. Disease severity was evaluated in two crop seasons and the accessions were genotyped through AFLP using four primer combinations. The clusters obtained based on the Jaccard genetic distance and Ward’s hierarchical clustering and those achieved by structure simulations had high concordance and were capable of establish two big clusters, one predominantly of common maize and another of popcorn. The association analysis was performed using four different statistical models. The more complete model containing both population structure and genetic relatedness narrowed the number of significant associations, demonstrating its importance to control false associations. A total of 19 significant marker associations were identified from which three (EactMctg18, EactMctg205, EactMctg169) are interesting candidates for further investigations.

title: Broiler carcass condemnation pattern during processing

description: ABSTRACT This study aimed to identify the influence of climate pattern and rearing conditions on broiler carcass condemnations observed during processing. We evaluated the registered data of 2015 from the federal inspection files in all broiler slaughterhouses located in the state of Mato Grosso do Sul, Midwestern Brazil. The percentages of condemnations by airsacculitis, cellulitis, dermatosis, ascites syndrome, total carcass condemnations, and average broiler weight at 42 days were analyzed. Data were associated with housing systems and season of the year in which each flock was reared. Two-way ANOVA was applied to the data in a completely randomized design 4×3 (four seasons and three houses) and compared by Tukey's test. The results indicated that the housing system did not affect the studied condemnations, and seasons of the year did not change condemnation by airsacculitis; however, the other pathologies leading to carcass condemnations were affected by season. Condemnations by cellulite were higher during summer than in winter. For dermatosis, the maximum index appears during summer and the lowest during winter and spring. The ascites syndrome presented the smallest index in summer and winter, and the minimum value was found in spring. The average bird weight was higher in autumn than in winter and spring. Type of broiler rearing did not affect the carcass condemnation index. Summer was the most detrimental period regarding the condemnation rates for the pathologies studied, mainly cellulitis and dermatosis, while the highest average weight of birds was found during autumn and spring.

title: Extraction and characterization of lignin from the pre-treatment of biomass for 2 nd generation ethanol production

description: ABSTRACT Biomass appears to be one of the few resources available with the potential of developing bio refineries for the inclusion of sustainable alternative routes in the production of energy and chemicals. Lignin is a 2nd generation by-product of biomass pre-treatment on ethanol production, and consists of carbon chains, which can have a high added value. However, lignin is being considered just for energy generation. Therefore, the aim of this study was to investigate the influence of pH in the precipitation of black liquor through its acidification of in different pH values (1-7), and to characterize the components of its chemical structure for possible future use. After determining the precipitated mass, a spectrophotometric analysis was carried out on infrared and ultraviolet, along with the quantification of total phenolic compounds in the solid and liquid fractions of lignin derived from different pH ranges. The results showed that the higher lignin concentrations were obtained at lower pH values. The instrumental analysis indicated significant differences in each lignin’s components, suggesting that its chemical composition is influenced by pH change. To conclude, the total concentration of phenolic compounds in the supernatant of the samples was lower at lower pH ranges, indicating that there are higher concentrations of these in lignin’s solid fraction.

title: Fatal work accidents in Palmas, Tocantins, Brazil: missed opportunities of information

description: Abstract Objective: to estimate the underreporting of fatal work accidents (FWA) in information systems of the Ministry of Health, State Secretariat of Public Security (SSP), Ministry of Labor and Social Security Secretariat, from 2007 to 2015, in Palmas, Tocantins. Methods: the data sources of the FWA cases were the Mortality Information System (SIM), the Hospital Information System of the Unified Health System (SIH-SUS), the Information System on Diseases of Compulsory Declaration (SINAN), the Annual Social Information Report (RAIS), the Information System of Communication of Work Accidents (SISCAT), police reports (PR), Cadaver Referrals (GEC) and Cadaveric Examination Reports (LEC). To calculate underreporting within each system, a single database was created with the records of all sources, eliminating repetitions. Results: 114 cases were identified. Under-reports identified were: SIM, 28.9%; SINAN, 44.7%; SSP, 55.3%; RAIS, 73.1%; SISCAT, 65.4%, for insured workers. Conclusion: the best performance in registry is from SIM. Extensive underreporting was observed in all other sources. Mortality records due to FWA are underestimated. Action to improve recording, especially at SIH-SUS, RAIS, SISCAT, and SSP, followed by SINAN and SIM, are required.

title: Water relations of chives in function of salinity and circulation frequency of nutrient solutions

description: ABSTRACT Hydroponic cultivation using saline waters is an alternative for agricultural production, especially in the cultivation of vegetables. Therefore, the present work was conducted with the objective of evaluating the water consumption, water use efficiency and water content, as well as dry matter partitioning of chives (Allium schoenoprasum), cv. Todo Ano Evergreen – Nebuka exposed to six levels of nutrient solution salinity (1.5, 3.0, 4.5, 6.0, 7.5 and 9.0 dS m-1), applied at two circulation frequencies (twice a day at 8 and 16 h; and three times a day - at 8, 12 and 16 h). The level in the nutrient solution reservoir, which decreased according to the water consumption by plants, was replaced with the respective saline water (Experiment I) and supply water (Experiment II). Both experiments used a completely randomized design, in a 6 x 2 factorial scheme, with five replicates. It was observed that increased circulation frequency and the use of supply water in the replacement mitigated the effects of salinity on water consumption, water use efficiency and water content in the plant. However, with the increase in nutrient solution electrical conductivity, dry matter allocation in the roots increased, to the detriment of the shoots.

title: Mensuração da Pobreza Multidimensional Rural nas Mesorregiões Norte e Jequitinhonha de Minas Gerais

description: Abstract: The aim of this study is to investigate and measure the intensity of rural multidimensional poverty through the Fuzzy sets, having as geographic cut North and Jequitinhonha mesoregions of Minas Gerais state and its familiar farmers as target public. The methodology is based on the construction of the Multidimensional Rural Poverty Fuzzy Index and on the calculation of the weights of each dimension. As for the results, these are aligned with what Amartya Sen defends in the Capability Approach, because although the dimension referring to income and work have presented the greatest weight in the measurement of poverty, factors such as education and health also merit attention due to the greater intensity presented. Therefore, this segment should be assisted by structuring policies with constant improvements in education, health and infrastructure, in order to meet the particularities of each locality, according to the real deprivations suffered by family farmers.
