title: Meat properties and fatty acid profile of swine fed cashew bagasse bran in qualitative food restriction program

description: ABSTRACT The purpose of this study was to evaluate the effects of qualitative dietary restriction diet on carcass characteristics, meat quality, fatty acid profile, and performance of finishing pigs fed diets containing cashew bagasse bran. Forty pigs (20 females and 20 males) with initial weight of 60.00±5.24 kg of body weight (BW) were used. The diets were formulated with corn, soybean meal, cashew bagasse bran, vegetable oil, and mineral and vitamin mixture for finishing pigs. The experimental design was in randomized blocks with five treatments and four replicates, with two animals per experimental unit, one of each sex. Parameters related to performance, carcass characteristics, meat quality, and fatty acids profiles were used. The treatments used in the experiment did not affect feed intake and daily weight gain; however, in relation to feed conversion, a linear effect was observed with the increase of cashew bagasse bran levels in the diet. The same effects were also observed in carcass yield, backfat thickness, and fat area. The meat:fat ratio increased linearly with the increase of fiber in the diet. The level of 22.5% of cashew bagasse bran in finishing pig diets is recommended.

title: Designing a Microstructural Array Associated with Hardness of Dual-phase Cu-Zn Alloy Using Investment Casting

description: A comparative investigation on the microstructural morphologies and hardness values of Cu-35 wt.% Zn and Cu-30 wt.% Zn with 1.5 wt.% Al content is provided. Distinctive specimens by using traditional investment casting were produced. Specimens withdrawn from distinct locations along the castings were thermally and microstructural analyzed. Thermally and chemically induced microstructural modifications affecting the microstructure and hardness are discussed. It is found that components (specimens) located at different positions along of the pattern tree casting have distinctive hardness values. This is associated with Cu segregation and cooling rate. It is also found that solidified piece under a cooling rate ~0.12 K/s has hardness 20% higher than the specimen solidified under 0.07 K/s. Duplex brass with Widmanstätten structure constitutes the resulting microstructure array. This seems to be associated with Al content, while both Zn and Al contents are associated with cooling rate as responsible parameter to induce Widmanstätten structure formation.

title: AGENCY FOR A SYSTEMIC COMPREHENSION OF WORK ACCIDENTS AND ORGANIZATIONAL ANOMALIES

description: Abstract Analyses of work accidents and organizational anomalies are traditionally based on external consultancy, or internal or external analysis, which generally fails in terms of the engagement and involvement of internal actors during the diagnosis or creating solutions. This paper aims to analyze if the interventionist method called Change Laboratory used in the analysis of organizational determinants and latent conditions of work accidents promotes agency and expansive learning of the involved actors, contributing to visualize/construct possible changes in the conception and development of the activity of construction of large buildings. Six sessions of Change Laboratory were analyzed to identify the micro-cycles of learning, facilitated by series of double stimulation. The sessions led to the engagement of the actors who created their own artefacts or appropriated the concepts or models, such as the timeline of the airport building, vicious circle, activity system, contradictions identified in origin of the anomalies and the possible solutions for future building projects. The study showed that the Change Laboratory can be used in systemic analysis of work accidents and anomalies. It is a powerful instrument for organizational collective learning when the group of actors becomes involved at comprehending, analyzing and creating solutions.

title: Aging and quality of life of elderly people in rural areas

description: ABSTRACT Objective: To evaluate the quality of life and health of elderly in rural areas of Minas Gerais State’s center-west. Method: Cross-sectional study, in four municipalities of Minas Gerais State, by interviewing elderly people. Associations between socio-demographic and quality of life variables were tested, separated into “satisfactory”/“unsatisfactory” with values from the median of positive answers. It was used the chi-square test, Fisher’s test and regression. Results: 182 elderly answered the questions and showed a relation with the “satisfactory” quality of life - bivariate (p &lt; 0.05): age by 69 years (61.6%), married (61.7%), living by 54 years in rural areas (68%), with no financial support (59.5%), living with someone else (61%), non-smoker (60%), presenting good health (76.7%), satisfied with life (69.6%); regression: not having financial support, living with someone else and not smoking. Conclusion: Elderly people in rural areas present good quality of life/health in the cognitive aspect, access to services, goods, habits, but awareness must be constant due to their weakness.

title: Fertilization of high-yield corn with poultry litter based on nitrogen doses

description: Abstract: The objective of this work was to recommend nitrogen doses from poultry litter-based organic fertilizers in powder and pellet forms, compared with mineral fertilizer, in a high-yield corn crop under no-tillage. The treatments consisted of a 3×3+1 factorial arrangement, with: three fertilizers, two organic derived from poultry litter in powder (OPo) and pelletized (OPe) forms and one mineral fertilizer (M); three N doses of 65, 100, and 135% of the recommended N requirement for corn; and an unfertilized control. After five corn crops farmed under no-tillage in a Rhodic Kandiudox, the recommended doses for fertilization with poultry litter organic fertilizers, with an expected yield equal to or greater than 8,000 kg ha-1, could be achieved from doses of 100 kg ha-1 N in OPe and M and of 121 kg ha-1 N in OPo. Increasing doses of the OPe, OPo, and M fertilizers raise the contents of organic carbon, N, and available P in the surface soil layer (0.0-0.1 m) and of exchangeable K up to a depth of 0.2 m, allowing to obtain N, P, and K contents in the plant tissue within the sufficiency range of the corn crop.

title: Nepheline syenites to syenites and granitic rocks of the Itatiaia Alkaline Massif, Southeastern Brazil: new geological insights into a migratory ring Complex

description: ABSTRACT: The Itatiaia Alkaline Massif comprises some of the largest meso-cenozoic alkaline igneous occurrences in Brazil, covering over 215 km2 between the states of Minas Gerais and Rio de Janeiro. It appears as an elongated, 30-km long and 4.5-11.5-km wide SE-NW-trending body emplaced along accommodation zones of the Continental Rift of Southern Brazil, intruding metapelites, orthogneiss and granites of the Brasília and Ribeira fold belts. New data and geological mapping suggest that the massif evolved from a migratory magmatic center manifested as ring structures and successive moon-shaped intrusions from SE to NW in three sectors of distinct lithological and geomorphological characteristics: Southeastern, Central and Northwestern. The lithological variants in the three sectors present themselves as discrete intrusive bodies, comprising feldspathoid-bearing and quartz-bearing syenites, porphyritic to breccioid trachytes, granite, monzonite, gabbro and trachybasalt, which can be grouped into 21 units. These rocks occur in five petrographical sets: plagioclase-free nepheline syenites, plagioclase-bearing nepheline syenite and pulaskites, nordmarkite-granite series, anti-rapakivi associations and basic rocks. Sin- to tardi-plutonic dykes of nephelinites, phonolites, trachytes and rhyolites are also present.

title: Produtividade Setorial e Mudança Estrutural no Brasil: Uma Análise Para o Período 1981 a 2013

description: This article aims to evaluate the relevance of sectoral productivity growth for structural change in Brazil in the period from 1981 through 2013, by implementing a dynamic general equilibrium model with three sectors. The calibrated model was used to simulate a hypothetical scenario where agricultural productivity would have grown at the aggregated economy’s productivity growth rate. Results suggest the agricultural productivity, the highest sectoral productivity in the period, was important to release labor to service sector, even though it may have marginally favored deindustrialization.

title: Physicochemical characterization and comparison of labels of beef bouillon cubes

description: Abstract This study aimed at determining the centesimal composition, the energy value and the sodium content in beef bouillon cubes and compare them with the nutritional information by the manufacturer. Beef bouillon cube samples were collected in supermarkets in of the city of Limoeiro do Norte/CE, and the levels of nutrients were determined by official analysis methods. The physicochemical analyses carried out were moisture, lipids, proteins, fixed mineral residue, total carbohydrates and sodium content. The beef bouillon cubes analyzed showed a low moisture content (3.23 – 4.23 g/100 g) and high levels of lipids (19.72 – 20.05 g/100 g) and fixed mineral residue (53.24 – 57.61 g/100 g). When compared to the data reported on their labels, all the parameters were in smaller amounts than the ones declared in all analyzed brands. The average sodium content found in the samples ranged from 758.5 to 815.5 mg/serving of the product. Considering that the results were based on a portion of broth and that these amounts are related to half a cube of beef bouillon, it becomes quite alarming the amount of sodium available in this type of product, since the food prepared with this ingredient is usually eaten alongside other foods, which also contain sodium in their composition.
