title: Wax Behavior in Crude Oils by Pour Point Analyses

description: Crude oils containing large quantities of waxes, and in situations where sudden temperature drops occur, a crystalline network can be formed, generating flow difficulties in production, transfer and offloading lines. Despite the scientific and economic importance of this phenomenon, correlations between the behavior of petroleum in relation to its pour point are scarce in the literature. In this work, nine crude oil samples were characterized regarding density, water content, wax fraction (one- and two-dimensional chromatography), pour point, yield stress and wax appearance temperature. The results showed that the storage conditions and oil characteristics had a strong influence on the pour point. Yield stress was influenced by initial temperature of the sample, cooling rate and shear rate during cooling. Finally, the content of aromatic compounds in oil with low concentration of n-alkanes can contribute to increase the pour point.

title: Food access and consumption in a rural settlement in Castanhal, PA, Brazil

description: Abstract The study aimed to assess the food accessibility and consumption among families in the Cupiúba rural settlement, in the city of Castanhal, Pará, Brazil. It was found that the access to food is worrying and indicated that most families are in food insecurity conditions. Moreover, income and food safety level were associated. The consumption of the settler families comprises mainly high-energy, low-nutrient content foods, characterized by the low intake of fruits and vegetables and the introduction of processed foods with high energy density and sugar-added beverages, although the traditional dietary habits (rice and beans) are still present. This configures a diet at risk for important nutritional deficits, obesity, and many non-communicable chronic diseases.

title: “OVERNOMINATION” OF TEACHERS AT THE PUBLIC EDUCATION SYSTEM OF THE STATE OF MINAS GERAIS (REDE ESTADUAL DE ENSINO DE MINAS GERAIS)

description: ABSTRACT This article presents a part of the results of a research with the teachers from the public education system in the state of Minas Gerais. Based on the exploration of the database of Minas Gerais’ State Education Department, the research revealed how many teachers have permanent employment contracts and how many of them have temporary contracts. Moreover, it shows how these numbers oscillated between 2009 and 2014. This might seem to be simple information, but it is rather difficult to be accessed, what makes it valuable. Besides surprising, the picture of “overnomination”, revealed by this study, is a major problem in the education management of Minas Gerais. It affects the quality of public education and claims for a rearrangement by the state in this field.

title: Anaconda-becoming: Huni Kuin image-songs, an Amerindian relational aesthetics

description: Abstract After depicting the contemporary scene of Huni Kuin ayahuasca shamanism and artistic agency, I analyze a selection of image-songs from this ritual. The songs unveil the workings of embodied perception and synesthesia, that is, the transductions of bodily sensations and perceptions in vision, rhythm, song and sound. The experience entails a process of other-becoming where to know means to see through the eyes of Other; to be covered with the skin/ornaments of those beings one has consumed and to sing through their voice. This other-becoming is a becoming in a deleuzian sense, which means that the lived experience is situated in-between the space of self and other. In this context the expression “you are what you eat” has specific implications for one’s health and for the acquisition of agentive and perceptive capabilities of other beings. The ritual technique of almost becoming consists of alternatingly producing and undoing temporary transformations through song.

title: Technologies applied to sorghum (Sorghum bicolor L. Moench): changes in phenolic compounds and antioxidant capacity

description: Abstract The search for foods with biological potential for the prevention of chronic diseases has highlighted sorghum, and numerous studies have been conducted to determine the best processing conditions without compromising the nutritional, functional or sensory qualities. We conducted a review of the scientific literature on the techniques used in sorghum and their effects on phenolic compounds and antioxidant capacity. This review allowed us to conclude that the type and content of phenolic compounds in the different varieties of sorghum must be considered for the selection of adequate technologies that allow the retention of phenolic compounds with improved bioaccessibility and biological potential. The available information has been mostly focused on the content of total phenols and the antioxidant activity of sorghum, while the digestibility, absorption, utilization and excretion of phenolic compounds have been poorly studied. In this regard, there is a clear need for further studies on sorghum with the aim of including sorghum as part of a healthy diet.

title: Carbon stock in the development of different designs of biodiverse agroforestry systems

description: ABSTRACT The objective of this study was to estimate the carbon stock in the different designs of biodiverse agroforestry systems (AFSs) in the region of the Environmental Protection Area (EPA) of Pratigi, Bahia, Brazil. Phytosociology aspects related to the potentiality of carbon stock of 10 farms were evaluated using plots of 10 x 50 m allocated in each AFS, inventorying 928 individuals of 17 families and 37 species, established in 2013. The biomass above and below the soil of the arboreal individuals were estimated by indirect method, using specific allometric equations for each species or group of species, with diameter above 1 cm. Carbon stock (CS) was estimated from the biomass. Cacao (Theobroma cacao) and rubber tree (Hevea brasiliensis) were the dominant species in all of the designs, which also contained fruit trees, and native and exotic shade trees. There was variation of the estimate of carbon stock (8.01-1.42 Mg ha-1) between the types of AFSs. The designs with a larger relative density of fruit and shade trees led to larger carbon storage, influenced by the wealth and diversity of species in the initial phase of establishment of biodiverse AFSs.

title: Pressure and angle of the seed-fertilizer drill press wheel on corn emergence

description: ABSTRACT In precision seed-fertilizer drills, the soil compaction mechanism is responsible for closing the furrow, pressing the soil over the seed. Among the available models, the most used is the V-type wheel system, with several options to regulate the wheel opening angle and pressure exerted on the soil. This study was carried out in the experimental area of the Federal University of Fronteira Sul - Campus Cerro Largo, in an clayey Red Latosol. Parameters related to corn emergence and the seedbed characteristics were evaluated at different regulations of opening angle and pressure of the compaction mechanism. The results indicate that mechanism regulations had no influence on emergence speed, emergence speed index and population of corn plants, under the studied conditions. However, the treatment with highest load and parallel alignment of the wheels caused lower values of elevated area and swelling. Treatments with 15° opening angle caused accumulation of soil in the center of the row, affecting the elevation height.

title: ANALYSIS OF THE PERFORMANCE OF A PACKED BED REACTOR TO PRODUCTION ETHYL ESTERS FROM CRUDE VEGETABLE OIL USING LIPASE IMMOBILIZED IN SILICA MODIFIED WITH PROTIC IONIC LIQUID

description: The objective this study was to evaluated the influence of silica modified with protic ionic liquid (PIL) on an immobilized biocatalyst by covalent binding of Burkholderia cepacia lipase (BCL) in a PBR and in the transesterification reaction, by characterization and mass transfer of the system studied. The results showed that maximum conversion of ethyl esters was 39 ± 1.73% at 96 h (IB on control silica) and 47 ± 2.0% in 72 h (IB on modified silica). The PIL also influenced the analysis of residence time distribution (RTD) with the mean time ranging from 14.94 (control silica) to 25 min (modified silica). Variation of the reaction parameters (temperature, flow rate and molar ratio) positively influenced the mass transfer coefficient (kc) which varied from 0.95 × 10−4 to 2.39 × 10−4 m s−1 (IB on control silica) and from 1.22 × 10−4 to 3.06 × 10−4 m s−1 (IB on modified silica).

title: Microstructure and Mechanical Properties of AA6061/AZ31B/AA6061 Composite Plates Fabricated by Vertical Explosive Welding and Subsequent Hot Rolling

description: In this study, three-ply Al/Mg/Al composite plates were successfully achieved by vertical explosive welding (EXW) method. After EXW, the sound joints were obtained. Then thin three-ply Al/Mg/Al EXWed composite plates with the thickness of 1.78 mm were achieved by hot rolling. The influence of annealing on the interface microstructures and mechanical properties of the thin composite plates was investigated. The results indicated that different morphology with big waveform and mini waveform was present in the explosively bonded interface. The interface shear strength was 91MPa for big waveform side and 92Mpa for mini waveform side. The rolled sample without annealing possessed the high ultimate tensile strength (UTS) value of 235Mpa and elongation of 8.5%. The equiaxed and homogeneous grain morphology of magnesium alloys in the thin three-ply Al/Mg/Al composite plates could be induced by annealing 300°C for 1 h. This contributed to the considerable increase of elongation by 18.5%.
