Estimativa da poluição emitida pelos ônibus das linhas troncais da cidade de Uberlândia, MG

The transport of people and goods contributes to the deterioration of the environment in urban areas because of the generation of pollution, such as, air, noise, soil, water or visual degradation. The heavy vehicles that use diesel as fuel are mainly responsible for the emission of nitrogen oxides (NOx) and particulate matter (PM), contributing to participation of the transport sector in air pollution. In addition, there is emission of Greenhouse Gas (GHG) whose main component is carbon dioxide (CO2). In most major cities, public transportation is often considered as a less polluting alternative compared to the private vehicle, in view of the potential to reduce, per passenger, the emissions of GHG and air pollutants. The study area was the city of Uberlândia and the objects of study were the trunk lines of the Sistema Integrado de Transporte (SIT). The emissions of NOx, PM and CO2 were estimated through the bottom-up approach which used the route of each bus line and also fuel consumption obtained through simulation from the TSIS software. The software has some result limitations, there are no report about the emission of pollutants by bus, and it is not able to change specifications for the fuel used by the fleet. The results obtained through calculations of pollutants and GHG emission by the bottom-up approach show that the emission is higher when using fuel comsuption obtained in simulation than using distance. For the results considering fuel and distance there was a reduction in emissions comparing ethanol and diesel.

Conduções cênicas: A “Açon” e o movimento através dos princípios e procedimentos metodológicos de Gilles Gwizdek

The research identifies and describes the principles and methodological procedures of the director Gilles Gaetan Gwizdek on the transposition of the dramatic text to the space of representation through action and movement. Besides that, it presents the results of the experiment in two different labor camps and conducting modes: the no-actor student, inserted into the basic education, and the actor-student, inserted in higher education. Through the scenic paths encountered by the director, the individuals were could find their own ways and verify, through the scenic conductions, how such methodological procedures can achieve a pedagogical thinking about the actor's work. As theoretical referential, were studied the artists-educators: Jacques Copeau, in what sensitizes to the use of dramatic text, and Jacques Lecoq, it approaches of the physical use of the actor's body to the theater. The concepts about theater of the scholars in theater: Constantin Stanislavski, Eugênio Barba, Meyerhold, Eugênio Kusnet, Bertold Brecht go through the theoretical revisions of the thinkers: Odete Aslan, Patrice Pavis, Ney Piacentini, Lúcia Romano, Flávio Desgranges e Anne Bogart, in what affects their practical experiences and conceptual about the text, the action and the movement. It was analyzed also the practical experience based on the principles and methodological procedures of Gilles director, in rehearsals and performances of students in the ninth grade of the primary school the Basic School of the Federal University of Uberlândia - ESEBA, as also, of the students of the sixth, seventh and eighth period, of the Theater Graduation in the same university. From this analysis, it was proposed an interrelation between the theoretical and practical works, done by reading of the artists-educators about movement and Gilles Gwizdek in his work process. The research suggests that, from the movement, the student can build autonomously a character through the experience of small movements of the body. Thus, this student would increase his relationship between stage and audience, and consequently, he would cause a possible state of "seduction" of the spectator to the spectacle.

A Influência do endosso de blogueiras no comportamento das consumidoras de moda no Brasil

The study about the celebrity endorsement has relevance for both the academia and businesses seeking to retain and attract customers through marketing communications. However, most researches conducted analyzes celebrities from the artistic or sports, and study the endorsement in print media or on TV. Few studies analyze the endorsement of influencers in social media. Observing this gap, the aim of this study is to verify if the endorsement of fashion bloggers influence on purchase intention of Brazilian consumers. In addition, other factors were analyzed for better understanding of the fashion consumer behavior: evaluation of the product, brand awareness, brand loyalty, product quality, involvement with fashion, and credibility of the endorser. Therefore, it held two studies. The first consisted of a qualitative exploratory research, which used focus groups to identify and understand how social media affect the behavior of consumers of fashion products. Among the main results of this study, we highlight the Instagram appointed unanimously as the main social media used by respondents for information on fashion, and the mention of blogger Thássia Naves as the main source of fashion reference in social media. In the second study was undertaken an experiment in which half of the sample had access to the image of a dress used by the blogger Thássia Naves on her Instagram, while the other half had access to dress image disclosed at the online store website of the product brand. The number of valid responses considered for the study was 465. To test the hypotheses of the study, we applied the t test for independent samples and ANOVA test for more than two groups. The survey results supported 5 of 8 hypotheses proposed. which were: The endorsement of the fashion blogger has a positive effect on purchase intention of the endorsed product (H1); The endorsement of the fashion blogger has a positive effect on the evaluation of the endorsed product (H2); The credibility of the fashion blogger has a positive effect on purchase intention of the endorsed product (H3); The credibility of the fashion blogger has a positive effect on the evaluation of the endorsed product (H4); and the credibility of the fashion blogger has a positive effect on brand awareness (H5). The other hypotheses have been disproved: The credibility of the fashion blogger has a positive effect on brand loyalty (H6); The credibility of the fashion blogger has a positive effect on the perception of quality (H7); and the credibility of the fashion blogger has a positive effect on involvement with fashion (H8).Within the scope of further analysis, it was found that involvement with fashion positively interfere in purchase intent, the evaluation of the product, brand awareness, loyalty to the brand, the pursuit of product quality and credibility of the endorser. Moreover, it was found that the frequency of access to Instagram for fashion information positively affects the purchase intention, in evaluating the product, the brand awareness in brand loyalty, involvement with fashion, and credibility endorser.

Determinação de teor de biodieseis de algodão e pinhão manso em misturas com diesel usando espectroscopia no infravermelho médio e quadrados mínimos parciais

Biodiesel is a renewable fuel derived from vegetable oils or animal fats, which can be a total or partial substitute for diesel. Since 2005, this fuel was introduced in the Brazilian energy matrix through Law 11.097 that determines the percentage of biodiesel added to diesel oil as well as monitoring the insertion of this fuel in market. The National Agency of Petroleum, Natural Gas and Biofuels (ANP) establish the obligation of adding 7% (v/v) of biodiesel to diesel commercialized in the country, making crucial the analytical control of this content. Therefore, in this study were developed and validated methodologies based on the use of Mid Infrared Spectroscopy (MIR) and Multivariate Calibration by Partial Least Squares (PLS) to quantify the methyl and ethyl biodiesels content of cotton and jatropha in binary blends with diesel at concentration range from 1.00 to 30.00% (v/v), since this is the range specified in standard ABNT NBR 15568. The biodiesels were produced from two routes, using ethanol or methanol, and evaluated according to the parameters: oxidative stability, water content, kinematic viscosity and density, presenting results according to ANP Resolution No. 45/2014. The built PLS models were validated on the basis of ASTM E1655-05 for Infrared Spectroscopy and Multivariate Calibration and ABNT NBR 15568, with satisfactory results due to RMSEP (Root Mean Square Error of Prediction) values below 0.08% (<0.1%), correlation coefficients (R) above 0.9997 and the absence of systematic error (bias). Therefore, the methodologies developed can be a promising alternative in the quality control of this fuel.
