title: Oral conditions and body weight in children from a public school in Manaus, AM, Brazil

description: Abstract Introduction Some studies have pointed to links between the prevalence of caries and periodontal disease, and the occurrence of overweight or obesity; but, few studies have been conducted in children. Objective To assess the relationship between periodontal disease, tooth decay and body weight in children from a public school in Manaus, AM, Brazil. Material and method The study included one hundred and sixty-nine children. Records were obtained of decayed, missing and filled (DMFT) permanent teeth, and of decayed, extracted, or filled (DEF) deciduous teeth, as well as the record of the community periodontal index (CPI). The classification of body weight category was obtained in percentile using the z-Score table. Result Higher averages of weight and body mass index (BMI) were seen in the overweight and obesity groups (p&lt;0.05). All groups were similar regarding the DMFT /DEF and CPI codes from 0 to 4 (p&gt;0.05). All groups showed higher averages of CPI 0 in comparison with other CPI codes from 1 to 4 (p&lt;0.05), and most of the children showed sites with probing depth &lt;3.5 mm and without bleeding on probing. Conclusion There was no relationship between body weight and the occurrence of dental caries and periodontal disease in the studied population. Obesity and overweight showed no negative influence on the increase in the prevalence of these diseases.

title: Sewage sludge compost for initial cultivation of eucalyptus

description: Abstract This study evaluated the feasibility of sewage sludge compost obtained from a sewage treatment plant as an alternative “Class D” organic fertilizer for the initial cultivation eucalyptus. The experiment was conducted in a greenhouse at CCA - UFSCar, Araras, SP. Cultivation occurred in 11 L pots for 75 days. We adopted a completely randomized design, with five treatments and seven repetitions. The tests considered a control treatment with no fertilization, three treatments with sewage sludge compost addition (25%, 50%, and 75% of the pot volume) and a treatment with conventional mineral fertilizers, all in sandy soil. At the end of the experiment, plant relative growth rate and dry mass were evaluated and submitted to analysis of variance, followed by a Tukey test at 5% probability. Treatments with fertilization had a greater relative growth rate than the control; however, we found no difference between mineral and organic fertilization. Plant dry mass was higher in the treatment with 50% of the pot filled with organic fertilizer. Thus, we conclude that the tested sewage sludge compost is a potential substitute for conventional mineral fertilization for the initial cultivation of eucalyptus.

title: FORAGE PRODUCTION AND PRESERVATION OF SPECIES BY ENRICHING CAATINGA WITH GRASSES AND THINNING AREAS INTO STRIPS

description: ABSTRACT The objective of this study was to evaluate the thinning into strips and the enrichment with exotic grasses in a Caatinga area in order to maintain and increase the biodiversity of native vegetable species and forage production. Two studies were carried out-one in an area of Caatinga thinned into strips and one in an unmanipulated Caatinga area-during the rainy and rainy-dry season transition periods in 2016. The production of herbaceous biomass was evaluated, and the diversity and equability of the two areas were assessed through Shannon-Weaver (H’) and Pielou (J’) indexes. The establishment of massai and buffel grasses at the center and edges of the area thinned into strips was also evaluated. During the rainy season, the production of herbaceous biomass in the area thinned into strips and the unmanipulated area was 1,228 kg ha-1 and 833.33 kg ha-1, while during the rainy-dry transition period, it was 1,973 kg ha-1 and 836.00 kg ha-1, respectively. The indexes remained similar: H’ (1.86) and J’ (0.74) for the area thinned into strips, and H’ (1.77) and J’ (0.85) for the unmanipulated area. The massai grass presented better establishment and development than that by the buffel grass in the center and edges of the area thinned into strips. Thus, thinning into strips increases the biodiversity of an area, and this combined with enrichment through grasses increases the biomass of herbaceous forage.

title: The vacuums of participatory planning in the formulation of local development plans in Bogotá

description: Abstract Citizen participation is currently one of the most important inputs to guide the planning processes of the public sector, in order to achieve an orientation of resources that best fits the solution of the most significant problems of society. For this, Colombia has regulatory frameworks, for the different territorial and administrative levels, aimed at regulating this process, as is the case of Agreement 13 of 2000, issued to guide the formulation of the development plans of the localities in Bogotá. However, based on the analysis carried out through semi-structured interviews applied to several actors involved in the process, it was found that the implementation of this norm, evidences gaps and defects of great relevance that endanger the validity of citizen participation for the local planning These gaps could be observed in three main aspects, such as the simultaneity of the district and local planning, the actors involved in the process and the mechanisms used to collect citizens' initiatives, and which are defined through methodologies that are elaborated in each locality.

title: ORGANIC MATTER AND CARBON MANAGEMENT INDEX OF SOIL TREATED WITH COMPOSTED AND NON-COMPOSTED LAYERED RESIDUES

description: ABSTRACT The use of organic residues and compost is a common practice to improve soil quality and content of organic matter. In this study, the labile and stable fractions of soil organic matter were evaluated after application of layers of fresh (non-composted) or composted organic residues in a 6-year-old citrus orchard. The experiment was set up as a randomized block design, with 6 treatments: control without NPK, control with NPK, non-composted organic residue (NCOR, with and without NPK), and composted organic residue (humus, with and without NPK), with three replicates. The treatments were applied under the plant canopy. Soil samples were collected from the 0-0.05, 0.05-0.10, and 0.10-0.15 m layers. There were increases of 10.3, 22.4, 16.3, and 37.1 % in the organic carbon contents of the surface soil for the treatments using NCOR without NPK, NCOR with NPK, humus with NPK, and humus without NPK, respectively. The organic carbon contents of the labile fraction varied from 1.0 to 12.8 g kg-1, representing between 8 and 62 % of the total carbon. The carbon concentrations in the stable fraction varied from 3.1 to 9.7 g kg-1, representing between 38 and 92 % of the total carbon, and this was the dominant fraction for most of the treatments.

title: The Neighborhood Impact Study (NIS) in the southern and southeastern regions of Brazil: advances and challenges to environmental urban management

description: Abstract The Neighborhood Impact Study (NIS) is a planning and management instrument that acts preventively at the urban impacts analysis and management proposals. Gaps persist for its implementation. The purpose of the article was to present a methodological roadmap for improving NIS regulation. Using qualitative research, it involved bibliographic and documentary research and case studies. It was initially identified the panorama of NIS legislation. Subsequently, the roadmap was presented, including nine process components: proposal presentation; screening; scope; development of a study; technical analysis; public consultation; decision; monitoring and follow-up. This script was verified in fourteen municipalities from the southern and southeastern regions of Brazil. To overcome technical, political and administrative challenges NIS perspectives of improvement were indicated. These include the need for greater procedure guidance; the NIS articulation with town planning licensing processes; guidance of public authorities in the conduct of urban development; enlargement of democratic spaces; integration of actions by different governmental institutions; development of networks between universities, municipalities and other institutions aiming at an education, confrontation and renewal of urban and environmental management of the country.

title: The Manzi projection: an imaging method used in dentistry for differential diagnosis of atheroma

description: ABSTRACT Atherosclerosis is a pathology of great importance worldwide, because of its direct relationship with cerebrovascular events, resulting in high morbidity and mortality rates. The possibility of atheromas being identified by means of panoramic radiography is consolidated in literature; however, limitations have been reported. Thus, the aim of the present clinical case was to demonstrate the possibility of using Manzi’s Projection, which is a technique that enables visualization of the carotid artery trajectory without superimpositions of other anatomic structures, capable of promoting differential diagnosis of calcified atheromas in the carotid artery during dental exams.

title: Endothelial Dysfunction and Pulse Wave Reflection in Women with Polycystic Ovarian Syndrome

description: Abstract Background: Patients with polycystic ovarian syndrome (PCOS) have an increased prevalence of metabolic syndrome and traditional atherosclerotic risk factors, such as dyslipidemia, diabetes and hypertension. Endothelial function and vascular stiffness are surrogate markers of early atherosclerosis, able to predict cardiovascular events. Objective: To compare endothelial function and pulse wave reflection between women with PCOS and healthy controls. Methods: Observational and cross-sectional study that included women with PCOS, age between 18 and 40 years-old and body mass index between 25.0 and 35.0 kg/m2, and healthy controls. Rotterdan criteria was used to diagnose PCOS. Subjects underwent clinical and anthropometric evaluation, laboratory and hormonal assays and imaging tests to measure pulse wave velocity (PWV), augmentation index (AIx) and brachial artery flow-mediated vasodilation (FMD). Kolmogorov-Smirnov test showed normal distribution of most parameters. Unpaired Student t-test was used with significance level established at p &lt; 0.05. Results: A total of 52 patients were included, 29 (56%) in PCOS group and 23 (44%) in control group. Clinical and laboratory parameters were similar between the groups. Women with PCOS had lower FMD (8.8 ± 1.0 vs 12.8 ± 1.2%, p = 0.021); PWV and AIx were similar between the groups (7.5 ± 0.2 vs 7.5 ± 0.3 m/s, p = 0.671 and 21.0 ± 1 vs. 20 ± 2%, p = 0.716, respectively). In the PCOS group, women with higher testosterone levels had higher AIx (25 ± 2 vs. 17 ± 3%, p = 0.045). Conclusions: PCOS women had endothelial dysfunction and those with higher testosterone levels had higher pulse wave reflection as compared with controls.

title: Simulation of the Mineração Serra Grande Industrial Grinding Circuit

description: Abstract Increasing throughput during the mining cycle operation frequently generates significant capital gains for a company. However, it is necessary to evaluate plant capacity and expand it for obtaining the required throughput increase. Therefore, studies including different scenarios, installation of new equipment and/or optimization of existing ones are required. This study describes the sampling methodology, sample characterization, modeling and simulation of Mineração Serra Grande industrial grinding circuit, an AngloGold Ashanti company, located in Crixás, State of Goiás, Brazil. The studied scenarios were: (1) adding a third ball mill in series with existing two ball mills, (2) adding a third ball mill in parallel with existing mills, (3) adding a vertical mill in series with existing mills and (4) adding high pressure grinding rolls to existing mills. The four simulations were carried out for designing the respective circuit, assessing the interference with existing equipment and installations, as well as comparing the energy consumption among the selected expansion alternatives. Apart from the HPGR alternative, all other three simulations resulted in the required P80 and capacity. Among the three selected simulations, the Vertimill alternative showed the smallest installed power.

title: Urban form and atmospheric pollution: assessing impacts in Rio de Janeiro

description: Abstract As cities have increased their role in concentrating the world's population, they have also become critical sources of pollution. This article investigates the possible impacts of urban form on air pollutant concentrations. Given the nascent state of this research field in urban studies in Brazil, we start with a panoramic view of the problem. Then the paper discusses the state of the art on interactions between pollution, natural elements and climate conditions; explores some air pollution impacts on humans and the environment, and the literature on relations between air quality and urban form, pointing to a general lack of research in the field. It suggests a way of modeling and testing these relation in a case study in the city of Rio de Janeiro. It does so exploring statistical methods to understand the distribution of key urban pollutants, namely sulfur dioxide (SO 2 ), carbon monoxide (CO) and particulate matters (PM); along with morphological variables (ground space index and building verticality); and meteorological factors (wind direction and speed, rainfall and air temperature). Results point to grades of influence of the ground space index and building verticality on pollutants concentration and suggest new avenues for empirical and methodological work.
