title: Spatial variability in soybean seeds quality and in chemical attributes of the soil of a production field in the Brazilian Cerrado

description: Abstract: The objective of this study was to evaluate the spatial variability in soybean seeds quality and in soil chemical attributes of a production field. Data were collected at 138 georeferenced points of a soybean production property located in Santo Antônio de Leverger - MT. Soil related variables, such as phosphorus, potassium, calcium, magnesium, and organic matter (OM) contents, pH, cation exchange capacity (CEC) and base saturation (V%) were evaluated. On the other hand, yield, one thousand seed mass, size, germination, emergence in seedbed, electrical conductivity, accelerated aging and tetrazolium reaction were evaluated as seed variables. The data were submitted to descriptive and geostatistical analysis, and the fit semivariogram parameters were used to elaborate spatial distribution maps of the analyzed variables. After the analysis, it was possible to conclude that there was spatial variability in the evaluated attributes for both seeds and soil related variables, indicating that the soybean seed production area can be divided into management zones, which allows the definition of areas to be harvested or discarded within a field of seed production.

title: Determination of periodontal biotype through analysis of intra-oral photographs

description: Abstract Objective To characterize the Periodontal Biotypes (PB) through photographs and verify the agreement with the clinical method of determination as well as with different Dental professionals. Material and method Standardized photographs and intraoral clinical evaluation of 34 patients (n = 34) were performed for dichotomous characterization of PB in thin and thick. The subjective assessment, through photography, was compared to clinical method of probing transparency. The PB determination by photographs was performed through the application of a questionnaire containing three categories (thin, thick intermediate) directed to 90 dental professionals. They were equally divided into 3 groups: general practitioners, periodontists and prosthodontists. The concordance in both comparisons was evaluated through the Kappa Test, in addition to the sensitivity and specificity tests. Result In the comparison between the clinical and the photographic method, there was no agreement (K = 0.264, p = 0.113). However, in the comparison between the groups of professionals, a low agreement (kappa = 0.160; p &lt;0.05) was found between periodontists and prothesis, as well as between prosthesis and general practitioners (kappa = 0.110; p = 0.142). Greater agreement, although weak, between periodontists and general practitioners (kappa = 0.291, p = 0.00). The questionnaire obtained a higher sensitivity and specificity value for the diagnosis of thick PB. Conclusion The evaluation of patients through clinical parameters is still necessary to characterize PB, since the determination using visual analysis using photography, regardless of specialty, was not effective, although thick PB was the most easily identified.

title: Performance of the Pentagon Drawing test for the screening of older adults with Alzheimer's dementia

description: ABSTRACT The Pentagon Drawing Test (PDT) is a common cognitive screening test. Objective: The aim of this study was to evaluate performance properties of a specific PDT scoring scale in older adults with Alzheimer's disease (AD) and healthy controls. Methods: A cross-sectional study of 390 elderly patients, aged 60 years or older with at least two years of education was conducted. All participants completed clinical and neuropsychological evaluations, including the Cambridge Cognitive Examination, the Mini-Mental State Examination (MMSE), and the Clock Drawing Test. All PDT were blindly scored with the scale of Bourke et al. Results: PDT analyses of the binary score on the MMSE (0 or 1 point) did not discriminate AD from controls (p = 0.839). However, when PDT was analyzed using the Bourke et al. scale, the two groups could be distinguished (p &lt;0.001). PDT was not affected by education, showed sensitivity of 85.5% and specificity of 66.9%, discriminated different clinical stages of dementia, and correlated with the other cognitive tests (p &lt;0.001). A 1-point difference on the Bourke et al. scale was associated with an odds ratio of 3.46 for AD. Conclusion: PDT can be used as a cognitive screen for suspected cases of dementia, especially AD, irrespective of educational level.

title: Marajoara Pottery and Círio de Nazaré: meaning and consecration of the Brazilian cultural heritage

description: ABSTRACT This article analyzes the processes of meaning-making and consecration of the Marajoara pottery and the Círio de Nazaré that enabled their recognition as part of the Brazilian cultural legacy. Based on reports from chroniclers, official documents and newspaper articles, the long process of assigning meanings to the Marajoara pottery and the Círio de Nazaré is historically related to a certain ideal of civilization and national identity. The conclusion is that, far from being a natural process, the conversion of these two cultural assets into Brazilian cultural heritage involved political issues and power relations implied in the production of discourses which valued some remnants while others have been silenced.

title: Elaboration and validation of a measure to evaluate the knowledge of primary care physicians in Brazil about nutritional recommendation for hypertension control

description: Abstract Background Primary health care physicians play a leading role in nutritional counseling to reduce hypertension related to morbidity and mortality. The literature is scarce on instruments validated for Brazil that evaluate the evidence based on knowledge of these professionals. Objective To elaborate a measure to evaluate the level of knowledge about nutritional recommendation for the control of hypertension for primary care physicians in Brazil. Method A validated instrument for the English language was used as the basis for the questionnaire elaboration, which was tested according to the fundamentals of the Item Response Theory. The dimensionality of the questionnaire was performed on the polychoric correlation matrix. For the estimation of the parameters of the items, the two Parameters Logistic Model (discrimination and difficulty) was used. Results Most of the items were considered easy, the discriminative power varied between high, moderate and low values. The absence of difficult items contributed to the imprecision of the measure among those with higher levels of knowledge. Conclusion The results show a measure that accurately measures physicians with a low level of knowledge, being a useful tool to identify professionals who need to improve their nutritional knowledge.

title: Environmental protection and shared management: a case study in the Metropolitan Region of Natal

description: Abstract In this paper, we aim to reflect on the relationship between the National Solid Waste Policy and the Metropolis Statute in order to understand the implications and challenges foreseen in these standards for the metropolitan regions in Brazil. Sharing solutions targeted at environmental preservation requires an agreement between different political and social actors, which sometimes creates obstacles to the existence of an effective policy. In this sense, we carried out a case study in the Metropolitan Region of Natal, in which we investigated, specifically, the shared management of solid waste in light of the federal law 12305/2010. The study showed lack of cooperation in the management of solid waste in the Metropolitan Region of Natal and revealed a scenario of noncompliance with the environmental law.

title: Application of persistent scatterers interferometry for surface displacements monitoring in N5E open pit iron mine using TerraSAR-X data, in Carajás Province, Amazon region

description: ABSTRACT: Carajás Mineral Province, Amazon region, is the most important one in Brazil. Vale S.A. Company has the right to operate in the area of the N5E mine. The work is conducted on rock alteration products of low geomechanical quality related to sandstones, siltstones, and a lateritic cover. In order to monitor ground deformation, 33 TerraSAR-X images covering the period of March 2012-April 2013 were used in the investigation. An interferometric synthetic aperture radar (InSAR) approach based on permanent scatterer interferometry (PSI) using an interferometric point target analysis algorithm was applied. Results demonstrated that most of the area was considered stable during the time span of the image acquisition. However, persistent scatterers (PSs) with high deformation rates were mapped over a landfill probably related to settlements. To validate the PSI data, graphs were generated with the displaced information based on topographic measurements in the field. The graphs showed that the surface deformations during TSX-1 runway coverage are within the miner’s safety threshold and do not present a risk of major problems. The PSI data provided a synoptic and detailed view of the deformation process that affects the mining complex without the need of field campaign or instrumentation.

title: Factors associated with pregnancy among adolescents of a municipality of northeast of Brazil

description: Abstract Background Early pregnancy is a prevalent public health issue that impacts on the health and social representations of young women. Objective This study aimed to investigate factors associated with adolescent pregnancy. Method A cross-sectional study was carried out with 234 women aged between 12 and 19 years (108 pregnant and 126 non-pregnant women). A questionnaire containing sociodemographic, obstetrical and behavioral variables was applied. For the analysis, the chi-square or Fisher's exact test was performed at a significance level of 5%. The odds ratio and the 95% confidence interval were used as measures of association between variables. A multiple logistic regression was performed considering the outcome of early pregnancy. Results The number of children, the planning of pregnancy and the use of contraceptive methods were significantly associated with teenage pregnancy (p &lt;0.05). In the regression, number of children (OR 0.22, 95% CI 0.10-0.48), exercise of paid activity (OR 0.46, 95% CI 0.22-0.94), and use of contraceptive methods (OR 0.42, 95% CI 0.21-0.80) are considered protective predictor variables. It was also showed that the non-planning of gravity increased 2.48 times the chance of early pregnancy. Conclusion Adolescent pregnancy is associated with sociodemographic, sexual behavior and family planning conditionalities.

title: Yield and technological quality of sugarcane cultivars under infestation of Diatraea saccharalis (Fabr., 1794)

description: ABSTRACT: The sugarcane borer, Diatraea saccharalis (Fabr., 1794) (Lepidoptera: Crambidae), is one of the main pests of sugarcane. This pest can reduce the quality and yield of the crop. Information on the quality and yield of cultivars in relation to the attack of sugarcane borer are necessary, since they guide the choice of the best materials for use in joint with other management tactics. Two field experiments were conducted in 2011 and 2012 to compare the quality and yield of 16 commercial sugarcane cultivars (IACSP93-3046, IACSP94-2094, IACSP94-2101, IAC91-1099, IACSP95-5000, IAC87-3396, RB92579, RB867515, RB966928, CTC2, CTC4, CTC9, CTC11, CTC15, CTC18 and SP86-0042) relative to the natural infestation of D. saccharalis. The experimental design was a randomized complete block with four replications. There was no difference between treatments for infestation index, with averages of 1.2 to 8.7% of bored internodes. Higher percentages of internodes with red rot were observed for CTC9, CTC2 and RB966928. The cultivars CTC4 and RB92579 infested with D. saccharalis resulted in lower technological quality, due the reduction in the contents of brix, apparent sucrose content (POL) and purity; and increase of the reducing sugars and, consequently, lower theoretically recoverable sugar (TRS). On the other hand, the lowest yields (t of cane ha-1) were observed for CTC18, IACSP94-2094, IACSP94-2101 and RB966928. Therefore, according to the hierarchical cluster analysis (UPGMA), the cultivars RB867515, CTC11, IAC91-1099, CTC15, SP86-0042, CTC2 and IACSP94-3046 were resistant to D. saccharalis.

title: Investigation of resistance of Salmonella spp. isolated from products and raw material of animal origin (swine and poultry)to antibiotics and disinfectants

description: ABSTRACT The genus Salmonella spp. Has worldwide geographical distribution, and represents a potential risk both to animal and human health. Inadequate use as well as continuous exposure to antibiotics and disinfectants might lead to the appearance of resistance of these microorganisms to antimicrobial compounds. The aims of this study were to investigate the occurrence of resistance in Salmonella spp., isolated from products and raw material of animal origin (swine and poultry), to antibiotics and disinfectants, and check whether the phenomenon of simultaneous resistance to disinfectants occurs among the antibiotic-resistant isolates. The test of susceptibility to antimicrobials (TSA) applied in 134 isolates indicated that 51 (38%) were resistant to at least one of the eight antibiotics used, and 28 (55%) of resistant isolates were multi-resistant. Resistant isolates were submitted to the test of quantitative suspension against four concentrations of disinfectants in three contact times, and the result was compared with that of the reference strain (Salmonella Choleraesuis ATCC 10.708). While the reference strain was sensitive considering the highest concentration (200 ppm) and the lowest contact time (5 min) as indicators, 12 (24%) isolates were resistant to cetyltrimethylammonium chloride (ammonia quaternary); the reference strain was resistant to chlorhexidine, which also occurred with 22 (43%) of the isolates; similar to the reference strain, all isolates were sensitive/inactivated by sodium hypochlorite and iodophore. There were no significant relations of simultaneous resistance between the antibiotics and the disinfectants tested.
