The objective of this research is to present a study on a relationship between the local head loss in connection of emitters in pipes with different diameters used in drip irrigation, with the online geometry of the emitter connectors, that allows an easy quantification of such head loss regarding of the size of the connectors. The experiment was carried out according to the Reynolds Numbers at a turbulent flow interval, obtained by the variation of the pipe outflow at a constant temperature of water. The results indicated that the friction factor of the Darcy-Weisbach equation can be estimated by the Blasius equation with the coefficients b = 0.300 and m = 0.25, for the above mentioned pipes. The head losses produced by the connections of the emitters, in relation to the pipe without emitter, was of 62%. A relationship between the kinetic load coefficient (K) and the index of blockage (IO) provoked by the online connector is presented by an algebraic equation which shows a coefficient of adjustment of approximately 96%.

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

INTRODUÇÃO: as oclusopatias estão entre os principais problemas de saúde bucal em todo o mundo, juntamente com a cárie dentária e a doença periodontal, e vários índices têm sido utilizados para registrá-las. OBJETIVOS: verificar a prevalência de oclusopatias utilizando a Classificação de Angle e o Índice de Estética Dentária (DAI), sua severidade e a necessidade de tratamento ortodôntico registradas pelo DAI, e comparar os resultados de ambos os índices, visando correlacionar o padrão dos dados coletados e a viabilidade de utilizá-los de forma conjunta. MÉTODOS: a amostra consistiu de 734 escolares com idade de 12 anos, de ambos os sexos, da rede pública do município de Lins/SP. Foram realizados exames nos pátios das escolas com utilização de sondas IPC a olho nu. RESULTADOS: pela Classificação de Angle, encontrou-se 33,24% das crianças com oclusão normal e 66,76% com má oclusão. Pelo DAI, observou-se que 65,26% das crianças apresentavam-se sem anormalidades ou com más oclusões leves. A má oclusão definida esteve presente em 12,81%, a má oclusão severa foi observada em 10,90% e a muito severa ou incapacitante em 11,03%. A maioria das crianças (70,57%) apresentou relação molar normal, e o overjet maxilar anterior foi a alteração mais frequentemente observada. No cruzamento dos índices houve semelhanças e divergências. CONCLUSÃO: o DAI não foi sensível a alguns problemas de oclusão detectados pela Classificação de Angle, e a recíproca foi verdadeira, demonstrando que ambos os índices possuem pontos distintos na detecção das oclusopatias, podendo ser utilizados de forma reciprocamente complementar.

Maxillary sinus lifting surgery is considered an excellent option for patient rehabilitation in cases of maxillary sinus pneumatization. This longitudinal study was performed in 41 patients to evaluate 51 maxillary sinus lifting procedures concomitant to autogenous bone grafted from mandibular ramus. Of the 107 implants installed, 28 were immediate fixations. Success index achieved regarding to bone graft was of 98.04%. The implants installed immediately or after bone grafting resulted in success rates of 92.86% and 94.59% respectively, with no statistically significant differences between them. Surgeries for bone grafting and immediate installation are considered a reliable treatment alternative provided that both anatomical structures and tissue physiology are kept in good conditions, with appropriate indication and techniques for good implant stability.
