title: Synthetic granite composite for precision equipment structures

description: ABSTRACT The structure is a component that plays an extremely important role in the equipment’s performance, it must withstand efforts without compromising the function, receive and transfer heat, dampen vibrations and position the elements, as well as promote ergonomics and aesthetics. In lightweight and precision equipment’s the raw material used must also allow thin walls, rigid, resistant and low density. The objective of the present work is the development of a synthetic granite composite for manufacturing of equipment’s structures. For this, an abundant Brazilian granite, a high strength epoxy resin and segmented carbon fibers were selected as materials. Test specimens, with maximized packing with granite gravel less than 2.0 mm were fabricated and tested for tensile strength, compression, flexural, damping, hardness, dilatometry, thermal conductivity and density. The maximized composition supported flexural stresses above 42 MPa, without fiber reinforcement and 51 MPa with carbon fiber reinforcement. The damping coefficient was about 7 times higher than cast iron, coefficient of thermal expansion of 1.4E-05 m/m.K, thermal conductivity coefficient of 1.2 W/m.K and density of 2.1 g/cm3. The developed composite showed potential for refining structures, with ease of molding of thin-walled elements, use of inserts, re-machining, providing economical manufacture of single parts, and is still able to perform the function with high damping coefficient and low weight.

title: Growth and reproduction in captivity unveils remarkable life-history plasticity in the smallnose fanskate, Sympterygia bonapartii (Chondrichthyes: Rajiformes)

description: ABSTRACT We analyzed growth and reproduction of captive-born smallnose fanskates Sympterygia bonapartii. Egg cases were obtained from oviposition of two females caught in the wild and held at Temaikèn Aquarium. Following hatching, growth was analyzed in 13 females and 21 males until sexual maturity. Pattern of oviposition activity and reproductive performance were evaluated in six of the captive-reared females. Four models were fitted to growth data, among which the logistic function was the one attaining the best fit. The highest growth rate for both sexes was recorded during the first year of life, whereas growth was significantly higher in females than in males during the second year. Size at first oviposition was 61.7 ± 3.5 cm TL, similar to wild specimens. However, captive-reared females reached maturity before two years of age, i.e. much earlier than wild skates, implying a significant phenotypic plasticity in this species. The similarity in size at maturity and the difference in age at maturity between captive and wild specimens indicate that there is a decoupling of both parameters mediated through growth rates. Captive-born skates reproduced successfully and yielded viable offspring, indicating that the environment at Temaikèn Aquarium is suitable for S. bonapartii to attain its full life cycle.

title: Thermographic images from healthy knees between dogs with long and short hair

description: ABSTRACT: The aim of this study was to investigate the influence of fur length in the evaluation of knees temperature in healthy dogs, using infrared thermography. This is a non-invasive diagnosis that is able to assess the microcirculation of the internal skin. Changes in temperature reflect from inflammatory reactions and vascular infarction to neurological disorders. Knees of 30 healthy dogs were analyzed, with up to 11 pounds of weight, screened by clinical examination and radiographic examination. Group A, consisting of 13 dogs with short fur, with 26 knees evaluated in total. Group B included animals with long fur, consisting of 17 animals, with 29 knees evaluated in total. The average temperatures of the cranial, lateral, caudal and medial sides of knees were analyzed. A significant difference between the groups was observed, with group A temperature being greater than the group B in all four analyzed faces. Comparing the temperatures of the faces in the contralateral limb, in both groups, the statistical analysis revealed no significant difference. In group A it was observed that temperatures in the cranial and lateral sides were similar, but different from the others. In group B, the statistical analysis showed the cranial lateral and caudal faces was similar, but differed from the medial side. The thermographic examination proved to be sensitive in the evaluation of temperature of small dogs’ knees;however, the length of the fur influenced the result.

title: Favorability potential for IOCG type deposits in the Riacho do Pontal Belt: new insights for identifying prospects of IOCG-type deposits in NE Brazil

description: ABSTRACT: Archean iron oxide-copper-gold (IOCG) deposits have been systematically described in the world class Carajás IOCG district, Amazonian region of Brazil. More recently, several Neoproterozoic (ca 1.13 to 0.96 Ga) IOCG deposits have been identified in the Riacho do Pontal mobile belt situated in the Borborema Province on the northern border of the São Francisco Craton. In these Neoproterozoic deposits, several copper occurrences have been mapped along shear zones. The primary hydrothermal mineral associations resulted in sodic, calcic-potassic and potassic-ferric alteration. The copper grades of the main prospects range between 0.5 and 0.8 wt% with an average of ~0.7 wt%. This study uses a fuzzy logic approach to create regional to district scale predictive exploration models. Specifically, multi-parameter geologic, geochemical, remote sensing, and airborne geophysical data incorporated into regional and local models predict known copper mineralization and, importantly, highlight prospective areas for new IOCG targets in the Borborema Province. At district scale, multiple higher resolution geological, soil geochemical, and airborne geophysical data that cover the Riacho do Pontal Belt, were analyzed. A drilling exploration program implemented on target RIA4 validated these model results. Drill hole RIA4-DH0001 crosscuts a mineralized zone with 32 m of 1.15 wt% copper.

title: Acrylamide replaced by moringa extract in sugar production

description: Abstract This manuscript showed a new product that can be used in sugar and alcohol production to replace the acrylamide polymer, applied in the juice treatment. This new product is an organic extract obtained from moringa seeds, which present the flocculating protein 2S-Albumin. This biomolecule is added in the decanter together with the limed and heated juice, increasing the sedimentation speed of impurities that, if remain in the process, decrease the quality of the obtained sugar. This issue is of great importance because the acrylamide molecule has carcinogenic and neurotoxic action in humans and may be incorporated within the sugar crystal or the mud (filter-cake) used as a fertilizer. Furthermore, it should be noted that this manuscript presents the best technique to extract the S-Albumin protein from moringa seeds (using a CaCl2 solution 0.1 mol/L), the best dosage to apply in the sugarcane juice (1300 mg/L), and similary sugar quality achieved, compared with the process using the acrylamide polymer.

title: LANGUAGE CONFLICT IN INTERCULTURAL INDIGENOUS TEACHER TRAINING COLLEGES

description: ABSTRACT Indigenous peoples’ presence in Brazilian universities has been increasing in the last years. While Indigenous cultures, languages and knowledge have been contributing to academic enrichment, such presence has also posed several challenges to these institutions. One of them has to do with the multitude of Indigenous languages in these environments. In order to contribute to this issue, this paper aims at discussing how language policies can be built in order to promote indigenous languages in a specific university intercultural teacher education program. It is argued that the development of new theories, epistemologies and methodologies in cooperation with indigenous people is needed in order to improve language policies in the academy.

title: Effect of different cooking procedures on cholesterol and fat contents of selected meat products

description: Abstract Meat products are important sources of dietary cholesterol and saturated fat. The serum cholesterol level, which is considered a risk factor for cardiovascular disease, reportedly increases with higher intake of saturated fats and cholesterol. In this study, the effect of different cooking procedures on the cholesterol, fat, and moisture contents on wet and dry bases of selected meat products was investigated. After frying the cholesterol content of lamb (p&lt;0.05), tail fat (p&gt;0.05), and beef fried with or without olive oil (p&lt;0.05) increased. However, sucuks (Turkish dry-fermented sausages) fried with or without olive oil exhibited lower (p&lt;0.05) cholesterol content compared to the initial values. After barbequing the cholesterol content of lamb kebab (p&gt;0.05) and hot spicy lamb kebab (p&gt;0.05) decreased, while the cholesterol content of liver kebab (p&lt;0.05) increased. The fat content of lamb (p&lt;0.05) and beef fried with (p&lt;0.05) or without olive oil (p&gt;0.05) increased, whereas the fat content of tail fat (p&lt;0.05) and sucuks fried with or without olive oil (p&gt;0.05) decreased. The fat content of kebabs did not change significantly (p&gt;0.05) after barbequing. Regardless of the meat product or cooking procedure, the cholesterol and fat contents on dry basis exhibited a significant decrease (p&lt;0.05) after cooking.

title: Multiband FSS Analysis and Synthesis Based on Parallel Non Coupled Metallic Strips Using WCIP Method

description: Abstract A novel parallel non coupled metallic strips frequency selective surface (FSS) is presented. The design is based on a filter composed of horizontal and vertical metallic strips. The structure has the advantage of simplicity and gives multi resonant frequencies easily controlled by a simple variation in the strips length. The proposed FSS rejects frequencies at 7GHz, 9.4GHz with bandwidths of 0.646GHz, 0.793GHz respectively when the structure is excited with an x polarized plane wave, and two frequencies at 9.1GHz and 11.2 GHz with bandwidth of 280.3MHz, 63MHz respectively when the structure is excited with a y polarized plane wave. To suppress frequencies ideal diode on reverse bias are inserted. The simulated results obtained using WCIP (Wave Concept Iterative Method) are compared to the COMSOL Multiphysics 4.3b software results, and measurements, a good agreement is observed. Then, an FSS synthesis approach based on non coupled parallel metallic strips is presented. It provides synthesized FSS with resonant frequencies ranging from 4.5GHz and 12.25 GHz for metallic strips lengths inversely varying from 5mm to 19mm. To validate the synthesis approach, measured resonant frequencies are used as desired resonant frequencies to determine the metallic strips lengths. As a result the metallic strips FSS dimensions are extracted. At this stage the WCIP method is used to characterize the synthesized FSS. Three FSSs are synthesized based on the fabricated FSS and good agreement between measurements and synthesized FSSs results is recorded.
