title: Initial growth and chemical composition of pornuncia plant fertilized with phosphorus and inoculated with arbuscular mycorrhizal fungi

description: SUMMARY The aim of this study was to evaluate the influence of phosphate fertilization and mycorrhizal inoculation on the initial growth, chemical composition and mycorrhizal symbiosis in Pornuncia (Manihot sp. – Euphorbiaceae) plant. An experiment was conducted in a completely randomized design in factorial arrangement with three concentration of simple superphosphate (P1 – 5.14mg/dm3, P2 – 49.3mg/dm3 e P3 – 98.6mg/dm3) and three inoculation treatments (not inoculated – NI, inoculated with Claroideoglomus etunicatum – CE or GA – Gigaspora albida), in three replications, during 90 days. It was verified that inoculation with CE promoted increase in leaf area and crude protein concentration in Pornuncia plants, while the GA isolate provided higher mycorrhizal colonization and glomerospores number. On the other hand, the addition of superphosphate reduces the mycorrhizal colonization in Pornuncia plants. Although the phosphate fertilization does not affect the growth of Pornuncia plants, the P2 concentration promoted an increase of 15,0% of neutral detergent fiber content. Inoculation with Claroideoglomus etunicatum in Pornuncia plants increases leaf area and crude protein content in the aerial part, and may contribute to the development and improvement of the chemical composition of this forage plant.

title: Association between birth defects and the use of agrochemicals in monocultures in the state of Paraná, Brazil

description: ABSTRACT This article aims to analyse the association between the use of pesticides and congenital malformations in cities with highest exposure to pesticides in the State of Paraná, Brazil, between 1994 and 2014. It is an ecological, quantitative approach study, conducted with live births information (Sinasc/Ministry of Health), generating malformations rates that have taken place in 1994-2003 and 2004-2014. A growing trend in congenital malformation rates was found in the state of Paraná, especially in the cities of Francisco Beltrão and Cascavel. These congenital malformations may be due to exposure of population to pesticides, and a significant signaling in public health problems.

title: Contribution of Litter and Leaf Decomposition of Byrsonima gardneriana

description: ABSTRACT The litter in tropical ecosystems is one of the compartments responsible for the transference of nutrients to the soil, having great importance for the conservation and maintenance of biodiversity. Thus, this study aimed to quantify the contribution and stock of litter and the leaf decomposition rate of Gardneriana byrsonima A. Juss (murici) in two areas of Caatinga, semiarid region of Alagoas State. Litter production was measured monthly from March of 2012 to February of 2013. The litter decomposition rate and the remaining leaf mass of the murici were also calculated and analyzed for its material chemically. The leaf decomposition was measured in litter bags and the material was chemically analyzed. In the area of Olho D'Água Casado, the litter produced was over Delmiro Gouveia. The leaf fraction contributed to the higher percentage in the litter training in both areas. The leaf material showed slow decomposition to high levels of lignin, cellulose, hemicellulose, and high C:N ratio.

title: HYDRAULIC AND TECHNICAL CHARACTERIZATION OF DRIPPERS NONSELF-COMPENSATING

description: ABSTRACT: This study aims to characterize and evaluate seven models of turbulent flow nonself-compensating drippers available in the Brazilian market. The characterization of the emitters followed the procedures of the standards NBR ISO 9261. The experiment was conducted at UNESP University Estadual Paulista, Botucatu Campus, Department of Rural Engineering. For the execution of the test one randomly took from each coil, segments containing 25 emitters. In the evaluation of hydraulic and technical characteristics of emitters were determined the following parameters: coefficient of manufacturing variation, coefficients of the characteristic equation of the emitter, thickness of the tube wall, internal diameter, spacing between emitters, water pressure resistance at ambient temperature and 40 oC, the tensile strength of the tube with a tension of 160 N and 180 N, and premature aging testing. The analysis of the drip tapes showed a coefficient of manufacturing variation of less than 0.056 for all emitters. The exponents (m) of the equation pressure versus flow rate ranged from 0.431 to 0.575, classifying them as nonself-compensating. About the wall thickness, the internal diameter of the drip tapes and the spacing between emitters were found out that all measured values are within the required standard. From the results obtained, it can be stated that all products tested and available in the Brazilian market showed satisfactory performance and quality.

title: Sampling Processes and Intensities for the Geostatistical Modeling of an Unevenly Aged Forest

description: ABSTRACT The aim of this study was to estimate the basal area, through traditional sampling processes and geostatistical interpolation, and compare it to the forest census carried out in 25 ha of a Mixed Ombrophilous Forest remnant. The sampling simulations were structured for the systematic sampling, two stages, and simple random, in intensities 5, 11, and 22% of the potential sample units of 25 × 25 m. The increase in sample intensity for the systematic sampling and two stages revealed a higher level of spatial behavior details of the basal area, whereas when comparing the census with sampling, it was observed that the geostatistical interpolation shows ability to improve the accuracy of the basal area estimation.

title: The impact of human resources policies and practices on organizational citizenship behaviors

description: ABSTRACT This study aims to investigate how policies and practices in human resources (PPHR) impact organizational citizenship behaviors (OCB). The OCBs represent additional contributions from employees to their organizations and, somehow, individual actions expected in crisis scenario or changing time by managers. The theoretical basis contains Milkovich and Boudreau (1994), Dessler (2002), Demo et al. (2012), among others, to address PPHR and Katz and Kahn (1978), Organ (1990) and Siqueira (2003) to OCB. We collect data from 156 employees of public, private and mixed companies located in the State of São Paulo. The results revealed significant impact from PPHR over OCB, and we evidence that only professional involvement exhibited significant relation. We also conclude that PPHR influence the dissemination of organizational image and creative suggestions from OCB factors. The results indicate suggestions where managers can act to extract, effectively, organizational citizenship behaviors from their employees.

title: Analysis of the social network of the Instance of Governance of the Caminho Novo Tourist Circuit, MG: a complex and systemic perspective,

description: Abstract The objective of this research was to analyze the composition, organization, and operation of the Caminho Novo-MG Tourist Circuit (CTCN), within the context of public tourism policies, supported by complex systems theory and using as theoretical support the complexity paradigm proposed by Edgar Morin, Beni’s SISTUR model (1998) and its reconstruction proposed by Moesch and Beni (2015, 2017). We used the snowball method applied in three steps, the analysis of social networks drawing on Granovetter’s (1973, 1983) weak and strong ties theory and Burt’s (1992) structural holes theory. Also, we used Bardin’s (2011) content analysis and the elaboration of sociograms of the relationships between social agents. As the main results, we highlight the lack of a regional network capable of producing useful results, the low understanding of the municipalities on public tourism policies, a substantial municipal and regional interference linked to a context of discontinuity of public management and a competitive position with reduced participation of social agents to work in a network.

title: Biometric and Physiological Responses to Water Restriction in Moringa oleifera Seedlings

description: ABSTRACT A water deficit in the soil can cause water stress in plants, triggering morphological and physiological changes. The aim of this work was evaluate the ecophysiological development of moringa seedlings under controlled water restriction. The experimental design was completely randomized at 40, 60, 80, and 100% of field capacity and six replicates. The photosynthetic CO2 assimilation, stomatal conductance, transpiration, vapor pressure deficit, internal carbon concentration, chlorophyll a, chlorophyll b, and total chlorophyll and stem diameter, height, and number of leaves were measured at 9 a.m. during 21 days of restriction. The treatments differed for photosynthetic parameters. Moringa seedlings reduce gas exchange to adapt to water restrictions until 40% of field capacity. The alterations promoted by water restriction did not negatively affected plant development.

title: Postural Discomfort in Manual Operations of Forest Planting

description: ABSTRACT This study evaluated the postural discomfort and health risks of workers in manual forest plantation operations of a company located in the region of Campos Gerais, Paraná State. Data was collected through interviews, using the postural diagram proposed by Corlett, in a sample of 226 workers from manual planting, fertilization and herbicide application operations. The results indicated that manual planting operations caused greater postural discomfort in the legs of 56% of workers, while the fertilization and herbicide application caused discomfort in the shoulders of 41% and 56% of workers, respectively. The perception of postural discomfort during work is important to assist managers in adopting ergonomic measures for improving the safety and health of workers.

title: Structural and Floristic Variations in an Atlantic Subtropical Rainforest in Southern Brazil

description: ABSTRACT The Atlantic Subtropical Rainforest covers a huge area of Santa Catarina state, starting on the coast and going through the Serra Geral. Along its distribution, the vegetation changes according to altitude, geomorphology, and soil. In the attempt to evaluate vegetation variations related to different soil types in an Atlantic Forest remnant, 43 plots of 200 m2 were sampled. All the individuals with DBH ≥ 5.0 cm were measured. We have found consistent floristic and structural variations, which separated sample plots with Litholic Neosol and Rogosol situated in slopes from those with Yellow-Red Ultisol and Haplic Cambisol, as well as plots with Fluvic Neosol from Haplic Gleisol in plateaus. Species richness increased according to water availability and soil depth, with the plateaus’ soils being the richest. Each area was characterized by a range of indicator species and the results indicated that soil attributes are important drivers of vegetation variation.

title: Evaluation of the dentin changes in teeth subjected to endodontic treatment and photodynamic therapy

description: Abstract Introduction Antimicrobial photodynamic therapy (PDT) is an efficient adjuvant technique to promote disinfection of the root canal system. Therefore, it is important to investigate changes to dentin morphology and permeability induced by the use of diode laser on the root dentin. Objective The purpose of this study was to investigate morphological changes and the percentage of apical leakage after the use of laser. Material and method Forty single-rooted teeth were instrumented using rotary system and irrigated. Teeth were randomly divided in two groups: G1 - not exposed to PDT (control), and G2 - pretreated with toluidine blue photosensitizer and irradiated with AsGaAl laser diode. Ten teeth in each group were evaluated by SEM for morphological changes. The other ten teeth were filled and stained with Rhodamine B to evaluate the apical leakage. Result The results showed significant difference between G1 and G2 (p &lt;0.001 - chi-square), with greater presence of debris in G1 and higher incidence of open dentinal tubules in G2. Erosions and cracks were observed in both groups, with no statistically significant difference (p&gt; 0.001). The apical leakage was significantly higher in G2 than in G1 (p &lt;0.001 - Student's t-test). Conclusion It was concluded that the use of low-level laser reduced the smear layer and opened the dentinal tubules. Use of laser increased the permeability of the apical dentin.
