title: Internacionalization of scientific production in Biological Sciences at UFRGS: 2000-2011

description: The aim of the article was to analyze the internationalization of scientific publications in Biological Sciences at the Universidade Federal do Rio Grande do Sul from 2000 to 2011 in journals indexed by Web of Science. This is a bibliometric study and internationalization was examined under three main dimensions: international diffusion, collaboration and impact. The international diffusion indicators show strong preference for foreign journals and the English language. The articles were published in journals from 37 different countries and the percentage of documents published in foreign journals was 81.9%. The international collaboration indicators reveal the prevalence of co-authorship in the publication of research results. International collaboration occurred in 22.4% of articles with the collaboration of 84 countries, particularly the United States, United Kingdom Argentina, Germany and France. The international impact indicators reveal a significant set of citing documents of scientific production, primarily consisting of articles published in foreign journals in English. International citing documents accounted for 77.8% from 168 different countries, particularly from the United States, United Kingdom, China and Germany. The results reveal that Biological Sciences at Universidade Federal do Rio Grande do Sul follow the trends of international publication and are in agreement with research conducted throughout the world. However, internationalization of scientific production does not occur regularly considering international diffusion, collaboration and impact.

title: Who Should They Relate To? A Study For the Identification and Analysis of Criteria to the Partners' Selection in Inter-Organizational Networks

description: ABSTRACT The selection of partners is strategic in inter-organizational networks. One of the most important aspects is the definition of criteria for selection, that are the minimal characteristics required from those prospected. This study aimed to identify the most important criteria for the selection of members in horizontal inter-organizational networks, also describing their influence on network activities. First, we applied 120 questionnaires to managers of inter-organizational networks to identify the degree of importance of criteria previously treated in the literature. After, we interviewed 16 managers enabling us to identify other criteria, as well as understanding their influence on network activities. All of the 20 criteria from the literature were considered with significant importance by managers and the following criteria were added: trustworthiness, entrepreneur's profile and company lifetime. The results aim to contribute to the selection of partners and provide information for the construction of the inter-organizational networks literature.

title: The Rio Pardo salient, northern Araçuaí orogen: an example of a complex basin-controlled fold-thrust belt curve

description: ABSTRACT: The Rio Pardo salient, the large antitaxial curve described by the Araçuaí fold-and-thrust belt along the southeastern edge of the São Francisco craton, is one of the most prominent and one of the least studied features of the Brasiliano Araçuaí-West Congo orogenic system (AWCO). In addition to the Archean/Paleoproterozoic basement, the salient is comprised of metasedimentary rocks mainly from the Neoproterozoic Macaúbas Group and the Salinas Formation. Its western limb occupies a portion of the Espinhaço ridge, where the NS-trending structures of the Araçuaí belt progressively curve NE and E, thereby defining the hinge zone along the Serra Geral on the Minas-Bahia boundary. The eastern limb is NW-trending and marked by a major shear zone. In models postulated to generate the AWCO through the closure of the Neoproterozoic Macaúbas basin, this large curve plays a critical kinematic role. Yet, in spite of this, its development is still not fully understood. How did this curve originate? Which factors controlled its generation? Our field study performed in the northern Araçuaí orogen characterized the kinematic picture of the salient, and led to a model that addresses these questions. The results we obtained indicate that the Rio Pardo salient developed in response to four deformation phases. The contractional D1 and D2 phases are coaxial and responsible for a craton-directed tectonic transport along the salient’s outer arc, which is coupled with an overall southward motion of the inner arc, thereby giving rise to a rather complex kinematic picture. Furthermore, structures of the D1/D2 phases define a zigzag pattern with alternating NE- and NW-trending segments along the salient’s leading edge. Along the NE-trending segments, the metasedimentary rocks are thrust northwestwards on top of the craton basement, while along the NW-trending segments, the supracrustal rocks are displaced along dextral to reverse-dextral transpressional shear zones located on the basement/cover contact. Structures of the D3 phase, which are well developed in the hinge zone, record a final WSW-ENE contraction, which was responsible for rotation of the preexistent fabric elements around NNW-trending axes and the enhancement of the salient curvature. The D4 phase is extensional and is recorded by two large-scale structures, the Chapada Acauã and Tingui normal shear zones, as well as by the normal-sinistral reactivation of the Itapebi strike-slip shear zone that marks the salient eastern limb. We interpret the initiation of the Rio Pardo salient during the collisional 565-575 Ma D1/D2 phases essentially as a primary arc that is mainly controlled by the geometry of the Macaúbas precursor basin. The thickened internal portion of the Rio Pardo salient was affected by extensional tectonism at c. 530 Ma, and is recorded by the D4 deformation phase, which is currently ascribed to the extensional collapse of the Araçuaí-West Congo orogen.

title: Socio-demographic factors and risk behaviors associated with alcohol consumption: a cutout of the Erica study

description: ABSTRACT Alcohol use impacts morbimortality in adolescence. Thus, this study aimed at identifying the relationship between alcohol, sociodemographic variables and risk behaviors among adolescents from the city of Belo Horizonte. Descriptive analysis and association tests and logistic regression were performed based on the data from the Study of Cardiovascular Risk in Adolescents (Erica). Alcohol consumption was found in 22.1% of the adolescents. The results of the multivariate analysis revealed that not using Oral Contraceptive (OC) in the last relation increased by 3.5 times the odds of adolescents consuming alcoholic beverage (OR: 3.5 CI95% 2.49-4.91). Smoking increased the chances of teenagers making use of alcoholic beverage by 7.25 times (OR: 7.25 CI95% 3.7-14,22). Male adolescents are 1.47 times more likely to consume alcoholic beverages than girls (OR: 1.47 CI 95% 1.14-1.89). Ageing increases 1.36 times the chance of adolescents using alcohol (OR: 1.36 CI95% 22-1.51). Presenting higher value of wealth proxy increased 1.04 times the chance of adolescents consuming alcoholic beverage (OR: 1.04 95% CI 1.01-1.07). Thus, it is concluded that health actions aimed at preventing alcohol consumption among adolescents should contemplate the differences between social classes, gender and age, as well as prevention of smoking and the promotion of sexual and reproductive health.

title: Numerical analysis of the liquid ejection due to the gaseous jet impact through computational fluid dynamics

description: Abstract Metal droplets generated by an impinging jet, play an important role in metal refining processes, mainly in oxygen steelmaking, where the droplets are ejected into the slag phase. Since the available interfacial area of droplets is very high in this process, the generated droplets enhance the rates of heat transfer and chemical reactions. Therefore, knowledge of the metal droplet generation rate, size distribution and residence time in the slag are of industrial relevance. In this work, the isothermal, transient flow of an incompressible air jet impinging onto an air/water interface at room temperature has been simulated to obtain a better understanding of the droplet ejection phenomenon. The interface was tracked throughout time using the volume of fluid (VOF) technique. The governing equations formulated for mass and momentum conservation and the k-e turbulence model are solved in the axisymmetric computational domain using the commercial code FLUENT. The droplet ejection rates calculated with computational fluid dynamics model are compared to experimental data reported in literature, showing partial agreement, being the incompressibility assumption the probable reason for the deviation observed, which was as far pronounced as the great jet velocity. Nevertheless, the model presented shows itself as a relatively good starting point for the construction of more complex ones (with less simplifying assumptions) which should be able to offer a means to increase the understanding of the droplet ejection phenomena.

title: Efficacy of chemo-mechanical preparation debridement procedures in disinfection of the apical third of human molar root canals

description: Abstract Aim The aim of this in vitro study was to evaluate the efficacy of chemo-mechanical preparation (CMP) debridement procedures in regard to cleansing and disinfection of the apical third of human molar canals using different protocols. Material and method Fifty mesial roots of human mandibular molars containing two canals were inoculated with E. faecalis strains and randomly allocated to five groups (n=10). CMP was carried out with the rotatory Protaper system associated with Kerr files #10 (G1 and G3) and #15 (G2 and G4). G5, the positive control, was subjected to CMP without debridement. Another variable studied was the use of calcium hydroxide-based temporary intracanal medication (Calen) prior to the chemo-mechanical performed in the G3 and G4 groups. Irrigation was performed with 2.5% sodium hypoclorite and 17% EDTA. Antimicrobial activity was quantified by counting the number of colony-forming units (CFU). Result Kruskal-Wallis was used for immediate analyses and Mann-Whitney for mediate analyses both with a stipulated value of significance of p=0.01. In the imediate analyses following CMP there were no significant differences among the groups (p=0.11). In the G4 (#15 + MIC) the results of the mediate collections were statistically significant (p=0.01). Conclusion Debridement with #10 and #15 Kerr files did not produce significant differences in regard to reduction of E. faecalis when compared to the positive control. In samples where Calen intracanal medication was used debridement with #15 Kerr files was more efficient in reducing the number of CFUs than #10 Kerr files.
