title: CONTRIBUTION OF COMPUTATIONAL SIMULATION FOR LAYOUT ANALYSIS IN A WOODEN FURNITURE INDUSTRY

description: ABSTRACT The objective of this study was to balance the production line and analyze the layout of the sewing sector in a furniture industry. Using the Arena software, a simulation model was constructed that represented the real system consisting of a cellular layout with 3 groups of 5 seamstresses, who produced 57 different types of products divided into three families, in a daily working day of 625 minutes in the months of February to August and 725 minutes in the months of September to January. The model was quantitatively validated among the managers of the studied industry. The obtained results allowed conclusions with an error of less than 1% in the daily quantity of pieces produced with 99% statistical confidence. Therefore, three scenarios related to the organization of the work environment and the balancing of the production line were constructed, and those include: i) linear layout, and the balancing allowed the division of five seamstresses for families 1 and 2, and three seamstresses for family 3; ii) study of the layout by processes, so that the best balance was constituted of two groups with seven seamstresses; iii) similar to scenario 2 but with six seamstresses in group 1 and seven seamstresses in group 2. It was verified that the modified, alternative scenario 2 is more advantageous for the organization, since it presents greater productivity compared to all other scenarios and to the real system, so the company can increase its production capacity by simply modifying the layout and organizing the work environment.

title: ANALYSIS OF EFFICIENCY OF FIRE DANGER INDICES IN FOREST FIRE PREDICTION

description: ABSTRACT Despite the existence of different fire danger indices, the use of an inefficient index can lead to making wrong decisions on the appropriate procedures for preventing and fighting forest fires, while a trusted prediction index can help the most quantification and allocation of resources for prevention. Thereat, the objective of this study is to analyze the efficiency of Fire Weather Index (FWI), Logarithmic of Telicyn Index, Nesterov Index, cumulative indexes of precipitation - evaporation (P-EVAP) and evaporation / precipitation (EVAP/P), Monte Alegre Index (FMA) and Monte Alegre Changed Index (FMA+) in the prediction of forest fires for the city of Viçosa (MG). The indices were compared using the method known as Skill Score (SS) taking into account the days that the indexes pointed to the risk of events with focus fire identified by satellite images on the 01/01/2005 to 31/12/2014 period. According to the results, the Logarithm of Telicyn Index (0.53257) as the most efficient for the study area, followed by the indices EVAP/P (0.46553), P-EVAP (0.43724), Nesterov (0.40445), FWI (0.39213), FMA+(0.34595) and FMA (0.28982).

title: WASTE WOOD OF URBAN ORIGIN FOR ENERGY USE

description: ABSTRACT The increasing demand for energy propels new areas of research in the search for sources that are economically viable and sustainable from an environmental point of view. In this sense, the objective of this study was to characterize a batch from urban wood waste aimed at energy use. We evaluate six different types of waste: solid wood, plywood, chipboard, MDF, OSB, and veneer. The residues were collected in a recycling plant in Piracicaba - SP and were taken to the laboratory to carry out the physical, chemical and thermogravimetric analyses. The experiment was conducted in a completely randomized design with three replicates per treatment (waste). Data analysis was performed by analysis of variance (ANOVA) and the Tukey test applied for multiple comparisons of means. Overall, there were no major differences between the results of solid wood residues and waste panels. Waste analyzed showed potential for energy use. It is recommended further studies to investigate the influence of different panels resins and coatings in its thermal degradation process.

title: Viability of polycultures of arugula-carrot-coriander fertilized with hairy woodrose under different population densities

description: ABSTRACT Polycultures from broadleaves with tuberoses are being used in vegetable crop production systems in the semiarid region of Potiguar. The challenge is to determine whether these systems are productively viable when fertilized with organic matter produced by spontaneous species of the Caatinga biome. The objective of this study was to evaluate the agro-economic performance of arugula (A), carrot (C), and coriander (Co) polycultures fertilized with hairy woodrose biomass incorporated into the soil under different population densities among the component crops. The experimental design was a randomized complete block with four replications, with the treatments arranged in a 4 × 4 factorial scheme, from the combination of four amounts of hairy woodrose biomass incorporated into the soil (7.5, 15.0, 22.5, and 30.0 t ha-1 on a dry matter basis), with four population densities (20A-50C-20Co%, 30A-50C-30Co%, 40A-50C-40Co%, and 50A-50C-50Co% of the recommended population in the single crop). The efficiency of polycultures was evaluated through indexes and agro-economic indicators. The most productive agro-economic performance was obtained with a biomass of 18.21 t ha-1 of hairy woodrose incorporated in the soil and a population density of 50A-50C-50Co%.

title: Anthropization Effects on the Filamentous Fungal Community of the Brazilian Catimbau National Park

description: ABSTRACT The Caatinga biome features an exclusive endemic biodiversity, and is characterized by the presence of xerophytic, deciduous vegetation, high temperatures, and low rainfall. This important park has undergone anthropization, especially through extraction of firewood and timber and growing plants for raising goats. The objectives of this study were to compare the communities of filamentous fungi present in the preserved area and in the anthropized soil of the Catimbau National Park in Buíque, PE, Brazil, and to evaluate the impacts of anthropization on such communities. A total of 12 collections of soil samples were made, six in the preserved area and six in the anthropic area, and the physicochemical properties of the soil samples were analyzed. Fungi were isolated through suspension and serial dilution methods. After growth, the samples were purified and identified based on classical taxonomy, according to specific literature. The diversity, evenness, richness, dominance, frequency, and similarity among the species of filamentous fungi in both areas were assessed based on ecological indexes. A total of 4,488 colony-forming units of filamentous fungi were obtained, which were distributed into 65 species belonging to 15 genera. In the preserved area, higher abundance and richness of species were observed, with predominance of the genera Aspergillus and Penicillium. In both areas, diversity and equitability were high, demonstrating that the species are well distributed in these areas. In the preserved area, the dominant genera were Aspergillus, Gongronella, and Penicillium, whereas Aspergillus was the dominant genus in the anthropic area. Two distinct communities were observed in the areas analyzed. Principal component analysis showed that Penicillium simplicissimum influences the total diversity of both communities. The anthropization that occurred in the Catimbau National Park has changed the composition of the filamentous fungal communities of the site, restricting the number of species and decreasing the abundance of these important microorganisms. This results in ecosystem damage and likely causes relevant major imbalances, with serious consequences, such as possible disappearance of the aforementioned species, as well as of species yet undiscovered by the scientific community.

title: Capturing deaths not informed to the Ministry of Health: proactive search of deaths in Brazilian municipalities

description: ABSTRACT: Introduction: The proactive search of deaths is a strategy for capturing events that were not informed to the Mortality Information System of Ministry of Health. Its importance to reduce underreporting of deaths and to evaluate the operation of the information system is widely known. Objective: To describe the methodology and main findings of the Proactive Search of Deaths, 2013, establishing the contribution of different information sources. Methods: The research was carried out in 79 Brazilian municipalities. We investigated several official and unofficial sources of information about deaths of municipality residents. Every information source investigated and all cases found in each source were typed in an on-line panel. The second stage of the research was the confirmation of cases to verify information of year and residence and to complete missing information. For all confirmed cases, we estimated the completeness of death registration and correction factors according to the adequacy level of mortality information. Results: We found 2,265 deaths that were not informed to the Mortality Information System. From those, 49.3% were found in unofficial sources, cemeteries and funeral homes. In some rural municipalities, precarious burial conditions were found in cemeteries in the middle of the forest and no registration of the deceased. Correction factors were inversely associated to the adequacy level of mortality information. Conclusion: The findings confirm the association between level of information adequacy and completeness of death registration, and indicate that the application of the proactive search is an effective method to capture deaths not informed to the Ministry of Health.

title: Effect of Obesity on Gestational and Perinatal Outcomes

description: Abstract Purpose To assess the impact of pre-pregnancy obesity (body mass index [BMI] ≥30 kg/m2) on the gestational and perinatal outcomes. Methods Retrospective cohort study of 731 pregnant women with a BMI ≥30 kg/m2 at the first prenatal care visit, comparing them with 3,161 women with a BMI between 18.5 kg/m2 and 24.9 kg/m2. Maternal and neonatal variables were assessed. Statistical analyses reporting the demographic features of the pregnant women (obese and normal) were performed with descriptive statistics followed by two-sided independent Student’s t tests for the continuous variables, and the chi-squared (χ2) test, or Fisher’s exact test, for the categorical variables. We performed a multiple linear regression analysis of newborn body weight based on the mother’s BMI, adjusted by maternal age, hyperglycemic disorders, hypertensive disorders, and cesarean deliveries to analyze the relationships among these variables. All analyses were performed with the R (R Foundation for Statistical Computing, Vienna, Austria) for Windows software, version 3.1.0. A value of p &lt; 0.05 was considered statistically significant. Results Obesity was associated with older age [OR 9.8 (7.8-12.2); p &lt; 0.01], hyperglycemic disorders [OR 6.5 (4.8-8.9); p &lt; 0.01], hypertensive disorders [OR 7.6 (6.1-9.5); p &lt; 0.01], caesarean deliveries [OR 2.5 (2.1-3.0); p &lt; 0.01], fetal macrosomia [OR 2.9 (2.3-3.6); p &lt; 0.01] and umbilical cord pH [OR 2.1 (1.4-2.9); p &lt; 0.01). Conversely, no association was observed with the duration of labor, bleeding during labor, Apgar scores at 1 and 5 minutes after birth, gestational age, stillbirth and early neonatal mortality, congenital malformations, and maternal and fetal injury. Conclusion We observed that pre-pregnancy obesity was associated with maternal age, hyperglycemic disorders, hypertension syndrome, cesarean deliveries, fetal macrosomia, and fetal acidosis.
