This article reports on the diversity and the linguistic variations in e-mails and chat interactions in teletandem interactions. Based on the interface of foreign language acquisition and sociolinguistics, its focus is on linguistic variants under the perspective of the social variations of language, especially regarding standard and non-standard norms of the Portuguese language in a teletandem context. Sociolinguistics offers us resources for the analysis and understanding that we intend to provide about teletandem interactions. We also mention the Teletandem Brasil project, its ideas and theoretical orientations, and also analyze data collected. The findings show that the variations in foreign students´ written production, who are also Portuguese learners, come from fluctuations between the standard and non-standard norms because students still do not have complete communicative competence in the target language.

The work presented here aims to evaluate how aesthetic norm variations influence the perception of attractiveness of a smile according to dentists and laymen. Methods: The smiles in photographs of a man and a woman were digitally changed. Eleven smiles were created for each one: an ideal, control smile - an ideal smile according to accepted norms - and 10 smiles containing individual variations of each of the following norms: a) 2mm and 3mm deviations from the middle line; b) the contour of the smile - contour of a straight smile and contour of a reverse smile; c) the angle of the lateral incisors - a mesial angle of 10° and a distal angle of 10°; d) 0.5mm and 1mm diastema; and e) dental proportion - Alber’s Proportion and Plato’s Proportion. The photographs were evaluated by two specialists in cosmetic dentistry and two laymen using the visual analogue scale. Results: The ideal smile for both genders was well accepted by both the specialists and the laymen. The opinions on the smiles with aesthetic variations varied, some were more positive than others, some were in agreement and some were in disagreement. Conclusion: The absence of deviations favors the perceived beauty of a smile, but some aesthetic variations seem to be better accepted than others. The success of aesthetic treatments depends on the active participation of dentists and patients in the planning stage.

On heat cured acrylic resins by microwaves energy the action of electromagnetic waves on methylmethacrylate promote the polymerization process. However, part of this energy is absorbed by the gypsum present in the flask and the function of this gypsum is to maintain the characteristics of specimen, nevertheless is unknown in the literature as the amount of water present in this gypsum affects the characteristics of acrylic resin. The proposal of this study was verified if dried gypsum influenced in some properties of the acrylic resins thermally activated by microwaves: presence of porosity, microhardness, roughness, flexural strength and dimensional change. Two different types of acrylic resin for complete denture were utilized: Lucitone 550 e Vipi-Wave and groups were formed: Lucitone 550, polymerization by microwave energy without gypsum treatment; Lucitone 550, polymerization by microwave energy with pretreatment gypsum; Vipi-Wave by microwave energy without gypsum treatment; Vipi Wave, polymerization by microwave energy with pretreatment gypsum; Lucitone 550 control group polymerization in hot water bath. For both situations were performed analysis of microhardness and porosity three different metallic shaped specimens were formed with followed dimensions: 2,0x2,0x2,0cm (8cm3); 2,0x2,0x1,0 (4cm3) e 2,0x2,0x0,5 (2cm3). Standardized wax specimens was used to prepare groups (n=9) and included in glass fiber flasks. The gypsum dry was made by microwave oven cycle (10min and 600W) and then the flasks were maintained in dry oven during two hours. Polymerizations of specimens were made and then polished. Wax patterns #7 obtained from the metal were embedded in plastic flask and following the processes of pressing and polymerization of the resin according to established groups. To evaluate the flexural strength, specimens 65mm x 10mm x 3.0mm from metallic patterns in bar format were made. ...

Hemogram values may have variations caused by intrinsic or extrinsic factors, which can take healthy animals to present values outside of the normal reference ranges and it is important to the veterinarian to know these variation factors for a correct results interpretation. The influence of the period of the day is among them. The objective of this study was to test the hypothesis that there are hematological parameters variations, such as erythrogram and plasmatic proteins during the day. The study was carried out with 10 non-pregnant adult goats in Araçatuba/SP/Brazil. The blood sampling and physical exam occurred at three moments between 07:00 and 08:00 a.m. (M1), 12:30 and 01:30 p.m. (M2), 5:00 and 6:00 p.m. (M3). We noted differences in the values of packed cell volume (PCV), hemoglobin, and rectal temperature through the moments, with reduction of PCV and hemoglobin were related to increase in rectal and air temperature, leading to water intake increase and, consequently, decreasing blood concentration. These variations could lead to an error of interpretation of the results due to values below the reference ranges.

Introduction: The fluoridation surveillance in the public water supply came up with the need to develop mechanisms that would help society in the control of water quality. To perform reliable analysis, variables such as depth of the wells and pluvial variations should be subject of research and study. Objectives: To analyze the fluoride levels of deep wells in periods of rain and drought, corresponding to four brazilian cities and compare the results. Methodology: It was made the mapping of the water supply network and the identification of the sampling points according to the number of deep wells in each locality, selecting those who had the natural fluoride level. Three points were defined for each source of water supply, and the addresses were randomly selected. The samples were analyzed in duplicate at the laboratory of the Center for Research in Public Health of the Dentistry School of Araçatuba – UNESP, during 8 months, in periods of rain and drought (total absence of rain). Results: 174 analysis were conducted, the mean fluoride levels for rain and drought times were, respectively: 0,71 and 0,73. It was used the Student’s t test (p <0.05). Conclusion: There wasn’t statistically significant differences for the periods of rain and drought in any of the cities, at the year of 2010. This study highlights the importance of health surveillance, because beyond of ensuring social control, there is also the search for investigating variables that may have directly and / or indirectly influence on the results of the analysis.

This article originated in a research that was meant to map out and examine the life conditions of “travesti” (transgender) teenagers and youth living in the city of Campinas, state of São Paulo. We contacted our informants outside the environments usually identifi ed as the common spaces where members of this group spend their time and share their experiences, as a strategy that we believed could enable us to better perceive how they construct their subjectivities. As we began our ethnographic endeavors, we were surprised by the multiplicity of ways in which these young people experimented with gender and sexuality, yet which were, at the same time, accompanied by eff orts to fi t these experiments within available identity categories. Feminine boys, cross dressers and drags thus constructed their own ways of living the feminine, and in doing so, stirred our imagination regarding contemporary experiences and political struggles in the realm of sexuality.

Nowadays, we live in a time of rapid research for technological advances, in a way that this pursuit of new technologies is deeply connected to the diversity of new materials that have been developed by mankind. It deals with issues such as materials with enhanced properties which offer better quality, less cost and high performance, while they are accessible both in their production and moment of operation. In this context, it was required to develop electrodes that were easy to prepare as well as which present high electric conductivity and good mechanic proprieties by using carbonaceous material as basis. For this reason, the best parameters of the furfuryl resin cures were established with different pH variations through viscosimetric measurements and differential scanning calorimetry. By scanning electron microscopy (SEM) was possible to identify an increased porosity in the samples with pH 7 and pH 8, as compared to samples with lower pH content. After carbonization of the material, the characterization of monolithic glassy carbon was held by means of FT-IR techniques, Raman spectroscopy, X-ray diffraction and cyclic voltammetry. The spectra showed that the change in pH does not have significant influence on the crystallographic ordering of the material and its structural characteristics. As for the electrochemical character, the CVM electrodes showed excellent response, with good reversibility and wide potential window. Some voltammetric curve deviations were only observed for the sample with pH 4, which may be related to processing parameters adopted
