title: Ultrasound spectroscopy as an alternative method to measure the physical-chemical constituents of buffalo milk

description: ABSTRACT: This study aimed to use ultrasound spectroscopy for the determination of the physical-chemical characteristics of buffalo milk and compare it to theinfrared method. Levels of fat, protein, lactose and non-fat solids (NFS) were determined in milk samples of 22 buffaloes (n = 383) with initial milk production of 6.97 ± 1.55 litres. The respective average results for the fat, protein, lactose and NFS of the individual samples were 6.31%, 3.81%, 4.99% and 9.75% for the infrared method-PO ANA 009 and 7.16%, 2.5%, 6.28% and 9.41% using ultrasound spectroscopy. There were significant differences (P&lt;0.0001) in the levels of all of the components analysed between the two methods studied. Results obtained in the analyses using the ultrasonic milk analyser (Ekomilk Total®) were different from those obtained by the infrared method-PO ANA 009 (ESALQ), but they showed a high positive correlation for fat (r =0.84108, P&lt;0.0001), moderate correlation for NFS(r= 0.71284 P = 0.0022), low correlation for lactose (r= 0.32197; P&lt;0.0001) and the absence of correlation for protein(r= -0.00284, P&lt;0.0001). Therefore, ultrasound spectroscopy can be used forthe determination of fat. For the other constituents of buffalo milk, in order to use the ultrasonic analyser, it is suggested that further studies should be conducted for technical and methodological adjustments.

title: Partisanship, life cycles and political socialization in Brazil

description: Abstract Empirical studies have shown significant differences in how young people and adults have expressed themselves politically, indicating that youth keeps distance from the involvement in conventional political actions, such as voting and party activism. These studies attribute the cause of this phenomenon to the differences between the social roles played throughout life by youth and adults. Despite the existence of studies that address the relationship between participation and age, there is a gap in the field about youth and party identification. This paper aims to analyze the effects of the transition to adulthood and party identification in Brazil. Using Brazilian Electoral Study data, produced by CESOP/Unicamp, this paper’s models show that there are no significant differences in party identification, whether it is rational or emotional, manifested by youth and adults. The dependent variable was not significant when controlled by other intervening variables, such as gender and education. In the models that analyze identification with the three major parties, being young was revealed as significant in explaining identification with PT and PMDB.

title: Cytotoxicity and antioxidant activity of goldenberry extracts obtained with high intensity ultrasound

description: ABSTRACT: The high intensity ultrasound-assisted extraction (HIU) is one of the most simple, quick and efficient techniques for the extraction of phenolic and other antioxidant compounds from plants. This is the first application of HIU for the extraction of these compounds from goldenberry fruit. The HIU and conventional extraction techniques showed similar results regarding to phenolic compounds and antioxidant capacity. However, the time required for HIU extraction (5min) was 24 times lower than conventional extraction (120min). Phenolic compounds reported were chlorogenic acid, caffeic acid and rutin. In vitro cytotoxicity assays were used for evaluation of extracts and the results showed that in a wide range of concentration, the extract maintains cell viability, thus indicating the possibility to use it as food with safety.

title: Retirement in the context of the Social Security Reform: descriptive analysis in a higher education institution

description: ABSTRACT In order to analyze the sociodemographic, work and health profile of the retirees of a public university, a cohort study was carried out through a retrospective data analysis of the retirees. The majority retired by age or time of service and presented good working conditions, health and good work ability. The favorable conditions for the maintenance of the active life in the work of these individuals can serve as an example for other professional categories in the Country. It is suggested, then, to think about the Social Security Reform along with actions of prevention of diseases and health promotion to prevent the illness, the loss of work ability and early retirements.

title: Participatory culture: citizenship-building process in Brazil

description: This study aims to describe the elements – context and resources –influencing social participation in a Municipal Health Council (MHC). It is a descriptive research using a qualitative approach. Data collection was done through direct observation of the MHC dynamics and semi-structured interviews with its members. Data analysis was based on thematic analysis, aiming to fit into the categories established by World Health Organization (WHO) regarding the dimensions of context and resources that influence participatory culture, such as: i) awareness related to political participation; ii) civil society organization; iii) structures and spaces; iv) resources; v) knowledge; and vi) impact of policies and past practices. As a result, authors found problems with regards to these components, as well as the fact that social participation is still weak and its biggest obstacles are related to communication between stakeholders and social institutions.

title: 3-D finite element analysis of the effects of post location and loading location on stress distribution in root canals of the mandibular 1st molar

description: Abstract Objective The purpose of this study was to evaluate, by using finite element analysis, the influence of post location and occlusal loading location on the stress distribution pattern inside the root canals of the mandibular 1st molar. Material and Methods Three different 3-D models of the mandibular 1st molar were established: no post (NP) – a model of endodontic and prosthodontic treatments; mesiobuccal post (MP) – a model of endodontic and prosthodontic treatments with a post in the mesiobuccal canal; and distal post (DP) – a model of endodontic and prosthodontic treatments with a post in the distal canal. A vertical force of 300 N, perpendicular to the occlusal plane, was applied to one of five 1 mm2 areas on the occlusal surface; mesial marginal ridge, distal marginal ridge, mesiobuccal cusp, distobuccal cusp, and central fossa. Finite element analysis was used to calculate the equivalent von Mises stresses on each root canal. Results The DP model showed similar maximum stress values to the NP model, while the MP model showed markedly greater maximum stress values. The post procedure increased stress concentration inside the canals, although this was significantly affected by the site of the force. Conclusions In the mandibular 1st molar, the distal canal is the better place to insert the post than the mesiobuccal canal. However, if insertion into the mesiobuccal canal is unavoidable, there should be consideration on the occlusal contact, making central fossa and distal marginal ridge the main functioning areas.

title: THE FEDERATIVE ARTICULATION COMMITTEE IN LULA’S GOVERNMENT: OBSTACLES IN TERRITORIAL COOPERATION

description: This article discusses how Brazilian federalism sought to promote municipal state capacities in Lula’s government (2007-2010) through the territorial cooperation between such entities and the Union. It analyzes the Comitê de Articulação Federativa [Federative Articulation Committee], which was an innovation in the federative arrangement with the municipalities, but which results, with time, distanced themselves from their original purpose. Based on international literature and on the case study, it argues that intragovernmental relationships – when organized via federative forums without decision authority and intragovernmental enforcement resources – reduce its capacity to implement pact actions with other entities. This is a qualitative study (pathway case) supported by causal explanations of similar cases. It contributes with the literature on the subject by showing the limits of intragovernmental arenas based on territorial logic, emphasizing that national systems of public politics, present in a few areas, have been more effective in federative cooperation.

title: Comparison of deflection forces of esthetic archwires combined with ceramic brackets

description: Abstract Coated archwires and ceramic brackets have been developed to improve facial esthetics during orthodontic treatment. However, their mechanical behavior has been shown to be different from metallic archwires and brackets. Therefore, the aim of this study was to compare the deflection forces in coated nickel-titanium (NiTi) and esthetic archwires combined with ceramic brackets. Material and Methods Non-coated NiTi (NC), rhodium coated NiTi (RC), teflon coated NiTi (TC), epoxy coated NiTi (EC), fiber-reinforced polymer (FRP), and the three different conventional brackets metal-insert polycrystalline ceramic (MI-PC), polycrystalline ceramic (PC) and monocrystalline ceramic (MC) were used. The specimens were set up on a clinical simulation device and evaluated in a Universal Testing Machine (Instron). An acrylic device, representative of the right maxillary central incisor was buccolingually activated and the unloading forces generated were recorded at 3, 2, 1 and 0.5 mm. The speed of the testing machine was 2 mm/min. ANOVA and Tukey tests were used to compare the different archwires and brackets. Results The brackets presented the following decreasing force ranking: monocrystalline, polycrystalline and polycrystalline metal-insert. The decreasing force ranking of the archwires was: rhodium coated NiTi (RC), non-coated NiTi (NC), teflon coated NiTi (TC), epoxy coated NiTi (EC) and fiber-reinforced polymer (FRP). At 3 mm of unloading the FRP archwire had a plastic deformation and produced an extremely low force in 2; 1 and 0.5 mm of unloading. Conclusion Combinations of the evaluated archwires and brackets will produce a force ranking proportional to the combination of their individual force rankings.
