Proposta de adequação à construção sustentável: tecnologias e alternativas para instituições de ensino

Due to the huge impact negative on the environmental caused by the civil construction, the university plays a majorital role in the proposal of studies and projects that aim the sustainable building. Nowadays, it has been noted the great demand for projects which contain a systemic focus in the tripod of the sustainable development, that is to say, more and more the consumers are demanding that the final result of a project contemplate the social, economic and environmental areas. According to the National Industry Confederation (CNI) and the Brazilian Chamber of the Industry and the Construction (CBIS), the goal for 2020 is that the constructions have an environmental performance 20% higher in comparison to the actual one, starting with an index defined by many indicators, such as: water consumption, energy, residues generation and social-environmental performance of the bought products. In this case, the theme of the project comes around the adequation of scholar institutions to the sustainable construction through simple changes of tecnologies and habits aiming the growth of the environmental eficiency of the enterprise and, consequently, the improve of sustainable practices inside the institution. Once the change is proposed, it will be furnished datas liable of reproduction for the adequation of others scholar institutions, according to it's necessity or interest. After the realization of the studies, it was possible to notice that the environmental performance of a scholar institution can be improved through the implantation of tecnologies of fast return in the investment, such as: flow reducers, rain water reuse system, green roof, retrofit of lamps and execution of a photovoltaic system. Besides the fast return of investment, the monthly economy of the applied tecnologies combined can reach 75% when compared to the actual spending with water and electric energy

O impacto do problema ambiental do fluido de corte nas indústrias e novas alternativas para sua utilização mais racional nos processos de retificação

Devido à constante preocupação do meio ambiente, o uso de fluidos de corte tem se tornado um problema para a indústria mecânica atual por se tratar de substâncias tóxicas. Seu uso e sua dificuldade de descarte devido rígida Legislação Ambiental, faz com que o fluido de corte seja responsável por uma grande parte do custo final do processo, provocando, desse modo, um grande interesse em pesquisas referentes a métodos alternativos de forma e quantidade de fluido de corte utilizado. Ao lado das vantagens tecnológicas associadas com o uso dos fluidos de corte estão os enormes perigos atrelados a estes, e que são nocivos ao meio ambiente e à saúde das pessoas. A contaminação do solo, água e ar podem decorrer de vazamentos e perdas, emissões, água de lavagem e da própria disposição dos fluidos de corte.Os componentes dos fluidos de corte como bactericidas e fungicidas reagem com outros produtos inseridos no processo de corte, tornando os fluidos, materiais que podem vir a causar doenças. Assim, este trabalho tem como objetivo apresentar a utilização do fluido de corte por mínima quantidade de lubrificação como alternativa para se minimizar o impacto ambiental das indústrias mecânicas.

Artes orientais de movimentos: alternativas às terapias do campo da saúde. uma possibilidade de investigação para a psicologia do esporte. um exemplo de pesquisa fenomenológica

This research analyzes the discourse of teachers of ancient oriental arts, namely: Yoga, Tai Chi Chuan, Kung Fu, Lian Gong, Qwan Ki Do, reveals the meaning that subjects have about what are the benefits to health of those already considered practical alternatives conventional treatment of health. The research uses the phenomenological method specifically the method of the phenomenon. The method first provides a pre-reflection on the oriental arts, exposing not systematically, some curiosities changing between aspects of oriental arts: historical, main teaching methods, styles, the character of struggle, why are linked to health, the benefits of their practices, movements, philosophy, concepts, ways of acting, the roots, the basics. In this article the pre-reflection does not appear to meet the standards of Congress page limit. Rather concentrate on the next step of the research and present the phenomenon situated in the experience of those who have experienced it in the case of the five arts teachers mentioned above. The method performs individual analysis or ideographic analysis of the five discourses of teachers from each oriental art and then conducts the general or nomothetic. The result is presented an analysis of generalities, convergence, divergence and individuality of meanings expressed by the subject, to finally develop a discussion of these data and weave a synthesis. The analyzes reveal that Eastern practices currently as some of these five analyzed here, those involving aspects of struggle and concentration are excellent allied health development and well-being. Understanding the philosophical aspect is inherent in the practice of the movements, although the character of the struggle, which they transmit through knowledge of their origins and roots is the current thinking routine that generates a life philosophy of selfhelp, self-enabling and tranquility preparation to overcome the tensions, disputes, everyday challenges. The speeches also reveal that the psychophysical aspects of diseases are real, because the practices of movements and the physical drilling of these oriental arts have enabled visible improvements in health by working the mental and the physical in an integrated manner. Masters must have all the knowledge to better meet today's society, preserving these cultures, passing them through the generations.

Aplicação da teoria fuzzy no controle de sistemas de geração de energias alternativas

This paper presents the application and use of a methodology based on fuzzy theory and simulates its use in intelligent control of a hybrid system for generating electricity, using solar energy, photovoltaic and wind. When using a fuzzy control system, it reached the point of maximum generation of energy, thus shifting all energy generated from the alternative sources-solar photovoltaic and wind, cargo and / or batteries when its use not immediately. The model uses three variables used for entry, which are: wind speed, solar radiation and loading the bank of batteries. For output variable has to choose which of the batteries of the battery bank is charged. For the simulations of this work is used MATLAB software. In this environment mathematical computational are analyzed and simulated all mathematical modeling, rules and other variables in the system described fuzzy. This model can be used in a system of control of hybrid systems for generating energy, providing the best use of energy sources, sun and wind, so we can extract the maximum energy possible these alternative sources without any prejudice to the environment.

Parcelamento de fontes alternativas de nitrogênio no milho safrinha em sucessão à soja

Increasing out-of-season corn productivity is possible by the application of nitrogen fertilizers even when in succession to soybean. On the other hand, information concerning the best sources of nitrogen and ways of splitting the doses to be applied is still scarce. Having that in mind, an experiment was carried out viewing to evaluate the effects of sources of nitrogen and ways of splitting doses of those N fertilizers on out-of-season corn sown in succession to soybean cultivated in a no-tillage system. The experiment took place in Chapadão do Céu, state of Goiás, Brasil (latitude of 18°35’42’’ South, longitude of 52°47’59’’ West and mean altitude above sea level of 802 m) in an Acrutox. The experimental units were distributed in the field in accordance with a randomized complete block design, in a factorial scheme 3 X 5 + 1, with four replications. Three were the sources of N: urea, urea extruded with starch (Amireia®) and ammonium sulfonitrate with a nitrification inhibitor (Entec®) and five the ways of splitting the nitrogen dose : 90-0, 60-30, 45-45, 30-60, and 0-90 in which the first fraction was applied at sowing and the second in side dressing. In addition to those, there was a check treatment, without N. All plots received, at sowing, 12 kg ha-1 of N by the mixture NPK. The ways of splitting the N dose and the sources of N had no significant effect on the levels of N and S in the leaves, first ear height, the final plant population, the number of ears per plant, and the number of grains per ear. N in the Entec® form at the highest doses applied in side dressing resulted in the highest grain yield, independently of the way the N dose was split. Only in the form Entec® the dose of 90 kg ha-1 of N increased grain productivity by 9.6% in comparison with the check treatment.
