Evaluación comparativa in vitro de la capacidad de sellado del sistema de conductos radiculares por diferentes técnicas

The aim of this study was to evaluate in vitro the sealing ability of the root canal using different techniques: cold lateral compaction, modified Hybrid Tagger, Thermafil and System B. Material and methods. Were used 116 human single-roots, included in resin blocks, sectioned longitudinally, attached to a device with screws and divided into four groups (n=29). After instrumentation using a bur, depression was made in each third of the root canal in each of the halves. Teeth were filled upon the different techniques. For evaluation of the quality, pictures were taken with a 1.5X magnification, photos and radiographs were utilized. After statistical analysis, were performed both macroscopic and radiographic evaluation, by Chi-square test (χ2). Results. The Thermafil technique showed better results in terms of sealing capacity, failures and homogeneity followed by modified Hybrid Tagger, the System B and cold lateral compaction. Conclusions. Thermafil was the technique that shown to be macroscopic, radiographic and homogeneously best over the other techniques evaluated in regard to the filling of the depressions made (AU)

Influence of spacing in the upper lateral incisor area on the perception of smile esthetics among orthodontists and laypersons

Background: The aim of this study was to determine the perception of smile esthetics among orthodontists and laypeople with respect to the presence of diastemas in the upper lateral incisor in the mesial, distal, and both surfaces using an oblique smile analysis. Methods: Two standardized oblique photos of pleasant smiles from two white women were selected. Images were digitally altered to create diastemas in the lateral incisor, in 0.5-mm increments, in the mesial, distal, or both surfaces. Final images were randomly assembled in a photo album, which was given to 120 judgesd60 orthodontists and 60 laypersons. Each rater was asked to evaluate the attractiveness of the images on a visual analog scale. The data collected were submitted to statistical analysis by the means of one-way ANOVA with the Tukey post hoc test and the unpaired Student’s t test. Results: The most attractive smile was the one without spacing, and the presence of diastemas was considered unattractive by both groups of raters, following a pattern: the greater and the more mesially located, the more unattractive was the smile. Conclusions: The results of this study suggest that diastemas in the upper lateral incisor area were considered unattractive, following a pattern: the greater and the more mesially located, the more unattractive was the smile.

Intra-examiner reproducibility of the agar plate method for estmation of phospholipase activity in candida albicans

Although measurement errors can impair statistical analysis, reliability analysis has been neglected in applied microbiology. This study assessed the intra-rater reproducibility of the Agar-based method for estimation of phospholipase activity (Pz). Pz readings were performed twice by two examiners (E1, E2), either directly on plates or in photos, and both black and white backgrounds were used. Pz values were taken from one or triplicate colonies from each sample (n=30). Intra-examiner reproducibility was estimated using Intraclass Correlation Coefficient (ICC). For both examiners, reading triplicate (ICCE1=0.91, ICCE2=0.86) was better than one colony (ICCE1=0.86, ICCE2=0.80). E1 had an excellent concordance when measurements were performed on photos using a white background (ICC=0.95) and a good concordance in the other conditions

O único luxo de um santo laico: fotografias em biografias de Clóvis Beviláqua

The jurist Clovis Bevilaqua (1859-1944) was a privileged member of a political and intellectual elite in the context of the transition from the nineteenth to the early decades of the twentieth century in this country, having been a professor at the Faculdade de Direito de Recife, author of the Civil Code of 1917, consultant for the Ministério das Relações Exteriores and jurist of international prestige, and literary critic and author of law, philosophy and history.Their biographies emphasize the breadth of his legal knowledge, the merits of civil codification which was author and lifestyle humble and generous earning him the nickname "secular saint". However, the lawyer had the habit of collecting photos of himself and of his family and this behavior is characterized as a single vanity for his biographers. From four biographies of Clovis Bevilaqua, written by Lauro Romero (1956), Raimundo de Menezes and Ubaldino de Azevedo (1959), Noemia Paes Barreto Brandão (1989) and Silvio Meira (1990), we intend to discuss how these images are used to illustrate the trajectory of the jurist and corroborate the distinct narratives models.

Avaliação dos fragmentos florestais do município de Jaboticabal-SP

Este estudo foi conduzido no Município de Jaboticabal, SP, com o objetivo de avaliar a evolução temporal e o número de fragmentos florestais no período de 29 anos, utilizando-se técnicas de sensoriamento remoto e fotointerpretação. Para a elaboração dos mapas foram utilizadas Cartas do IBGE de 1971 e fotografias áreas de 2000. Os resultados apontaram diminuição das áreas de floresta. em 1971, o município apresentava 3,63% da área total com fragmentos florestais, e em 2000 observou-se, apenas, 1,55% dessa área. Tal fato ocorreu tendo em vista o avanço de práticas agrícolas com predominância da cultura de cana-de-açúcar. A porcentagem de fragmentos florestais em 1971, com áreas menores que 10 ha, era de 46,72%, já em 2000 esse número passou para 78,51%, concluindo-se um processo de fragmentação acentuado (31,79%) no período analisado. Os fragmentos florestais com maior extensão em 1971 se apresentaram extremamente fragmentados em 2000. Aproximadamente 60% dos fragmentos, nas duas épocas, apresentavam forma alongada, indicando alta relação perímetro/área.

Redes sociais na Internet: uma investigação sobre práticas de compartilhamento de arquivos no Facebook

The social networking sites have experienced a large and rapid growth in recent years and bring together millions of users in Brazil and worldwide. Such networks allow adding groups of people with common interests or relationships, enabling members of this group to communicate and exchange information. Some social networks have specific goals, for example, aggregate individuals with common interests and professional relationships. However, they all share information in some way, whether in the form of short texts, photos, videos, among others. Sharing information in files is also a growing activity on the Internet and can be done in various ways, from sending files via email to multiple contacts to make available areas shared by the same contacts. However, applications are not yet available to enable file sharing on Facebook, considered the premier social network today. Given the growing demand for sharing files over the Internet, and a large number of users familiar with the use of these integrated applications for Facebook there is a demand for applications that allow users to share files with their contacts in this social network. This study aims to investigate how users use Facebook, and their practices for file sharing. It is believed that the results will substantiate future projects to develop software for file sharing on Facebook. Due to the exploratory nature of this research, the choice was made for a survey to collect data, applied through the web. From the results obtained, was possible to observe a frequent use of file sharing, but no interest in paid services. Regarding Facebook, was possible to observe their extensive use in both the frequency of access as the hours spent, as well as an increased use of applications (games, quiz, etc.). The full set of results shows a favorable environment for developing applications for sharing files on Facebook.

Relações entre proeminência facial nas fotos do Orkut e o perfil dos usuários

Relationship Between Facial Prominence of Orkut’s Photos and the Users’ Profile This research aimed to verify the relation between facial prominence index (FPI) and the profile of 600 users of Orkut. The results demonstrated that in all evaluated segments the average of male facial prominence was higher than the female; women increase the prominence while men decrease it as they become older and university graduates women have presented higher prominence than high school graduates. Significant differences were also found in the categories of humor when comparing the FPI between the genders and between persons of the same gender. In summary, the results indicate that the determinant factors for the facial prominence presented at Orkut are probably related to both biological and cultural aspects.
