In our analysis of Antonil, author of Cultura e opulência do Brasil, we oppose to the historiography that analyses him as a writer who examines Brazilian society of the late seventeenth and early eighteenth centuries, sometimes from a religious perspective, others from the economy perspective. Thus, the historiography sometimes explains him as an author who has a religious vision of society, others as an author who would have an economic view of it. In our viewpoint, both ways to consider him fail for being extreme. To comprehend him, it is necessary to understand him from the issues he has dealt with and how he dealt with them. Only then we can reconcile the religious and economic aspects of his worldview.

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. ...

The goal of the present study was to investigate possible differences towards strenght recovery measured by different methods and running economy (RE), after one session of downhill running (DR), in order to induce muscle damage (MD). Our hypothesis is that the strenght recovery measured by jumps is more alike RE markers, due to the measures' specificity. Ten male subjects, ages 18 to 30, apparently healthy, without any experience with strenght training at least 6 months before the tests took place in this study. After going to the lab twice (to familiarize themselves with the protocols, and determine their maximum oxygen consumption/running speeds), they went to the lab five times in the following week, in order to collect all the variables before, immediately after, and 24, 48, 72 and 96 hours in. The variables obtained were: stride frequency (SF), stride lenght (SL), oxygen volume (VO2), carbon dioxide volume (VCO2), ventilation (VE), lactate blood concentration ([Lac]), isometric peak torque (IPT), subjective pain perception (SPP), effort perception (EP), medial-portion circumference (CIR), knee movement extent (EXT), torque development rate (TDR), counter movement jump and squat jump height (HCM and HS), strenght development rate of both jumps (SDCM and SDS), and maximum soil strenght reaction (SRCM and SRS). Changes over time in all variables were verified by one way variancy analysis. Differences between the strenght measures were verified by two way variancy analysis. When significant effects were verified, Tuckey's post-hoc were applied. The significancy level taken on this study was p < 0,05. Of all indirect muscle damage markers, IPT, SPP and TDR were the only ones in which ocurred significant changes. We couldn't find the moments where this happened for TDR with the post-hoc used. On RE markers, VO2, [Lac] and VE suffered significant effects over time. About the jumps variables, only SDCM and HCM presented significant...

Creative spaces need freedom. Any productions, especially with artistic content, need space to mistakes, that is, for an attempt away from the standard. The independent production environment is recognized in different artistic sectors as a space for innovation, to be free of the serial production logic. The major innovations in the international scenario of games came from the independent productions. Great classics revolutionized the aesthetics and functionality of this new media. This project aims to analyze the productive chains of Brazilian independent games, starting with a regional analysis. The goal is to observe the factors responsible for the innovation that these games can offer, the management aspects of creative processes, articulation of innovative agents and resources mobilized. Brazil currently has the fourth largest gaming market in the world with expectation of strong growth for years to come, but arises in the international market as a consumer. Given this regional demand is necessary to study the tools of production, even to help fill that need. Not only the production of games should be thought, the media coverage is also another important factor, in view of the economic importance of this segment. Understanding the mechanisms of innovation in the gaming universe, its impact on the formation of public and coverage of specialized journalism in this new media are possible outcomes of future studies and research that scientific research can contribute

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.
