Estudo sobre iluminação e banco de capacitores de uma típica indústria metalúrgica

The use of electricity for obtaining light has been quite an issue currently discussed, either through new technologies that are emerging, the quest for greater efficiency, reduced waste and rational use. This work comprises a lighting design applied to a metallurgical based Brazilian Standard 5413 which mentions levels of luminance for interior and, in the case of this work, for a sandblasting booth. Ways to improve the workplace and luminosity presented before the project and also after its implementation are discussed. Technologies are chosen guided by technical calculations according to the illuminance values they want to reach for the environment studied. All pertinent design features are critically analyzed and discussed, and at the end proposals are presented, relating to each other in a comparative framework, so the best solution is applied in a practical way in the enclosure. Results are also presented concerning the maintenance of a bank of capacitors to correct the power factor for the metals studied company

Motivos de permanências nas vivências em atividades físicas de aventura na natureza

O meio urbano cresce rapidamente a cada dia tomando o lugar das árvores, da vegetação e dos animais silvestres. Esse crescimento, associado ao desenvolvimento de novas tecnologias que visam facilitar o cotidiano das pessoas, muda as práticas habituais, afastando a população citadina das atividades físicas e da natureza. Nesse contexto as atividades realizadas em meio natural vem conquistando um interesse cada vez maior de pessoas, que as procuram por diversas razões. Baseado nessa curiosidade procurou-se investigar os agentes incentivadores à permanência nas práticas do rapel, do cascading e do canyoning. O estudo teve uma natureza qualitativa e constou de pesquisa bibliográfica aliada à pesquisa exploratória, a qual utilizou como instrumento para coleta de dados questionários mistos, aplicados a uma amostra intencional composta por 10 praticantes de cada uma dessas modalidades citadas. Os dados foram analisados descritivamente, pela Técnica de Análise de Conteúdo Temático e indicam que o ambiente natural associado a estas práticas, bem como, a perspectiva de fuga do cotidiano e a possibilidade de ampliação das relações interpessoais, representam algumas das importantes influências para a permanência nas atividades físicas de aventura na natureza.

Estudo das representações do mundo do trabalho de alunos do meio rural através do uso de mídias virtuais

This paper aims to present the representations of the working world of high school students, the State School Prof. Dr. João Deoclécio da Silva Ramos, Distrito de Talhado, São José do Rio Preto (SP), through the use of virtual media, specifically the Blog de Aula – Mutirão de Sociologia (www.mutiraodesociologia.com.br). Understanding the representations of the world work enables students to think of a profession which identify themselves, and stimulate reflection as future professionals. The virtual media, especially blogs, allow students to express their ways of living and thinking the world of work. In the context of the city of Rio Preto, is especially relevant these representations of the world’s rural work, so this project is to collaborate in the development of research concerned with the description and understanding of processes that involve relationships between work, education and rural.

Competences in the classroom in the perspectives of foreign language teachers

In this article we raise some considerations about teachers’ competences, from the perspective of teachers in the Brazilian public sector. The theoretical framework includes articles by Paulo Freire (2001), Philippe Perrenoud (2012), Edgar Morin (2003) and Maurice Tardif (2002) and, based on these authors, we reflect upon issues concerning teachers’ competences taking answers provided by the Brazilian language teachers as a departing point. In a teachers’ course, followed by the same teachers, we posed the main question in our study: Which competences are necessary for a teacher to be considered a good professional at present? From the answers given individually and group discussions we proceeded to a comparative analysis with the adopted framework, and other issues concerning teachers’ competences were considered as well. All the participants mentioned the same two competences, the use of technology and sound knowledge of the course content, and other competences were pointed out by the various teachers as well. Such procedure, besides providing data for our study, also helped as a self-reflexive activity for the teachers involved, about their own professional performance. Given the issues raised in the theoretical texts and the answers provided by the teachers, we expect to revisit the competences necessary for foreign language teacher efficient performance.

Estudo preliminar do potencial de alguns asteroides

A survey we conducted, and bring expressed in this text is a preliminary study on the shape of asteroids and allowed us to understand a little more the dynamics around these bodies, in order that the images we have of asteroids are the most irregular possible. In this work, the asteroid is modeled by the method of the polyhedron, which provides a very good accuracy of the irregular shape of the body. Through study of models for non-spherical gravitational potential bodies, implementation of computational algorithms and numerical simulations a preliminary analysis was performed in relation to the shape of asteroids 4179 Toutatis, 6489 Golevka, 2063 Bacchus, 1620 Geographos and 1998 ML14, as well as regions of stability instability, we compute the coefficients of the gravitational potential. The work not only enables expansion for the case of asteroids, but also for other non-spherical bodies, contributing to the development of targeted studies the origin and evolution of the solar system, and perhaps the origin of the earth, and new technologies for modeling and mapping of non-spherical bodies. The main results were obtained by analyzing the graphics format and planning of asteroids, which confirmed how these bodies are irregular and show how distribution of non-homogeneous mass. Observe the behavior of the curves of zero velocity and equipotential curves as well as their respective surfaces. Also, compute some values of the gravitational potential and the spherical harmonic coefficients of each object. Furthermore, we find possible equilibrium points of asteroids except 4179 Toutatis, and analyze its stability

Sistemas de filtragem aplicados em processos fabris automotivos

The present work resulted from a study about coolant filtration systems in industries with metalworking process in large scale. The filtration and element filter world markets move billions of Reais per year and have a promissory future considering that with the global requirements of sustainable economic development, many companies invest in new filtering technology. Either known as coolant or cutting fluid, it is used to lubricate e cool parts during machining and is necessary due to the high volume demanded in the several machining operations and to the high cost of the product. Therefore, there is the need for recycling the product after its use. The work shows the technology and fundamentals of filtration as well as different filtering elements, filtration systems and scale contamination used in the industry. Also, there is a differentiation between filtration of the surface type (cake) and depth filtration and shows the basic theory of filtration by mathematic models in different operational conditions. Ultimately, project criteria for a coolant filtration system selection is shown followed by technical-operational details of a real vacuum filtration system and a case study aiming the operational cost reduction of the system

Derivados estruturais do peptídeo Histatina-5: síntese e aplicação no tratamento de candidose bucal

O uso contínuo de antifúngicos tópicos e sistêmicos no tratamento convencional de candidose oral tem resultado no aparecimento de Candida albicans resistente. Por este motivo, novas tecnologias para o desenvolvimento de drogas, como os biofármacos, constituem uma estratégia, além de inovadora devido a seu mecanismo de ação, também promissora no campo da biotecnologia. Verificou-se que esta nova tecnologia possui potencial efeito em diminuir a resistência de microrganismos, especialmente do agente etiológico da candidose bucal. A Candida albicans, agente patológico de origem fúngica, expressa diversos fatores de virulência sendo comumente encontrada na pele, cavidade oral, esôfago, trato gastrointestinal e órgão reprodutor feminino podendo acometer pessoas de idades variadas, imunologicamente comprometidas, ou que utilizam próteses dentárias. Nesse sentido, peptídeos com efeito antifúngico, produzidos por plantas, animais e microrganismos estão sendo utilizados como modelos para o desenvolvimento de novas drogas com aplicações em saúde. A Histatina 5 é um peptídeo encontrado na saliva humana com forte propriedade fungicida in vitro. Este peptídeo é extremamente rico nos aminoácidos histidina e lisina e, em pH fisiológico, possui potencial de inibição da formação do biofilme de Candida albicans, podendo ser aplicado portanto, no tratamento da candidose oral. Nesse contexto, o presente estudo consiste na obtenção de análogos da Histatina-5 com modificações em sua estrutura molecular, com o objetivo de otimizar o seu potencial terapêutico já verificado nos peptídeos da família das Histatinas. A Histatina 5SC possui o aminoácido serina C-terminal substituído pela cisteína, o qual é constituído pelo grupo sulfidrila em sua cadeia lateral, para a formação de dímeros. Os peptídeos foram desenvolvidos sinteticamente pelo método de Síntese Orgânica em Fase Sólida, utilizando-se a estratégia Fmoc e...

Autonomia e reflexão nas práticas telecolaborativas em teletandem

New technologies have been playing an important role in providing access to foreign languages and cultures and to authentic communication. Telecollaborative practice can enrich foreign languages teaching and learning and the teachers’ formation processes. This paper focuses on the possibilities that emerge in teletandem for learners to practice autonomy and reflection. Teletandem is a distance tandem modality performed by audio and video conferences with tools such as Windows Live Messenger, Skype or ooVoo. This modality is presented by Teletandem Brasil Project: foreign languages for all. Based on a qualitative ethnographic study with Brazilian and foreign students, the results have shown that teletandem provides and encourages reflexive and autonomous attitudes.

O professor e a prática telecolaborativa no teletandem

The new technologies have increasingly provided access to foreign languages and cultures and also to authentic communication. If we consider that the foreign languages teaching/learning process and teachers’ education can be enriched by telecollaboration, I believe it is necessary to observe the roles played by language teachers. Based on an ethnographic qualitative study carried out with Brazilian and foreign university students, this paper focuses on teletandem practice, a distance tandem modality carried out by audio and video conferences with resources such as Windows Live Messenger, Skype or ooVoo, to investigate roles played by language teachers in telecollaborative practice. The data were collected from (a) e-mails exchanged between the partners and between partners and the mediator-teacher; (b) DVDs of interaction sessions recordings; (c) written teletandem sessions recordings; (d) recordings of interviews between the partners and the researcher at ooVoo; (e) fi eld notes taken at Teletandem Laboratory at UNESP- Assis; and (f) participants’ written reports. The data analysis, from the hermeneutic interpretative perspective, revealed that the teacher is not ignored but is given new roles to maximize the process towards meaningful and intercultural learning.
