25. Analysis of energy fluxes and vegetation-atmosphere parameters in irrigated and natural ecosystems of semi-arid Brazil.
Knowledge on evapotranspiration is essential in quantifying water use depletion and to allocate scarce water resources to competing uses. Despite that an extensive literature describes the theoretical mechanisms of turbulent water vapour transport above and within crop canopies fewer studies have examined land surface parameters within composite landscapes o

26. Desempenho lumínico em edificação escolar com estratégias sustentáveis e bioclimáticas : um estudo de caso
New manners on how to inhabit the planet are sought due to the increasing society development, in order to preserve it for the future generation. The seeking for low-energy consumption alternatives is one of the key issues the man can intervene in order to preserve earth´s natural resources. The usage of natural light is extremely valuable in edifications w

27. Simulação computacional integrada para a consideração da luz natural na avaliação do desempenho energético de edificações
A luz natural é uma importante estratégia para redução do consumo de energia em edificações. Para sua previsão, recomenda-se a utilização de programas de simulação que empregam arquivos climáticos e processam as simulações com o conceito do Daylight Coefficients. O EnergyPlus, programa para simulação termoenergética, é uma dessas ferramenta

28. Análise do desempenho luminoso através de uma janela em sacada : estudo comparativo para os climas de Maceió, Brasil e Valparaíso, Chile.
This present dissertation focuses on the study of the daylight performance produced by the use of Bow Window in the residential sector. The system Bow Window is a simply designed window facing outward from the façade. Moreover this architectural element is influenced by a multitude of cultural trends and imported from various parts of the world. Nowadays in

29. Luxlogger - autonomous system of daylight measurement of low cost / Luxlogger - sistema autônomo de medição de iluminação natural de baixo custo
The environmental issue has now created major discussions on renewable energy, being one of the major sources is the sun. However, the exploitation of its energy light has not yet been done on a large scale in countries that have such availability, such as Brazil. One reason may be the lack of a better understanding of how to make scaling of natural light. T

30. Integração de iluminação natural e artificial: métodos e guia prático para projeto luminotécnico
The efficient use of the lighting in architecture depends upon the study of the daylighting availability and its integration with the electric lighting system. This research concentrates and organizes systematically theoretical bases on lighting design, with special attention to lighting analyses methods. It is based on the bibliographic review of the existe

31. EMISSÃO DE GASES DE EFEITO ESTUFA EM SISTEMAS DE MANEJO EM SOLO DO PLANALTO MÉDIO DO RIO GRANDE DO SUL / SHORT-TERM GREENHOUSE GASES EMISSIONS IN SOIL MANAGEMENT SYSTEMS IN OXISOL OF SOUTHERN BRAZIL
Agriculture is directly linked to atmospheric concentration of greenhouse gases (GHG) through basic processes that occur in the soil-plant system. Agricultural soils can act as a source or sink of GHG depending on the management practices adopted. The objective of this research was to evaluate the GHG flux in different soil management systems. This project w

32. Iluminação natural em projetos de escolas: uma proposta de metodologia para melhorar a qualidade da iluminação e conservar energia / Daylighting in schools projects: a proposition of a methodology to enhance lighting quality and energy savings.
This work aims to analyse daylighting strategies applied in early stages of architectural design as to improve lighting quality and energy savings in school buildings. Similar strategies have already been successfully applied in many countries around the world, enhancing student?s performance and well being while helping to save energy. Among the strategies

33. Refrigeração evaporativa por aspersão em telhas de fibrocimento: estudo teórico e experimental
This research focuses the evaporative cooling by water aspersion on wavy cement fiber tiles in the city of São Carlos, SP, seeking to use it to reduce the buildings heat gains. A theoretical model was developed, based on classic equations of fluids mechanic, applied to iterative calculations of heat flows on the tile superior surface, considered as control

35. Influência da luz natural refletida pelo entorno na iluminação de edifícios no trópico úmido
The development of the urban space has a great impact on daylight availability. Urban design can improve the use of daylight in buildings. Climatic conditions influence the availability of daylight considerably and should be taken into account by Urban Codes. In the humid tropic, the sky factor may decrease due to the use of the solar protection. That has be

36. AVALIAÇÃO HIDROACÚSTICA DOS EFEITOS CAUSADOS POR BANCOS SUBMARINOS E ILHAS SOBRE A DISTRIBUIÇÃO E DENSIDADE ACÚSTICA DE ORGANISMOS PELÁGICOS, NA ZONA ECONÔMICA EXCLUSIVA DAS REGIÕES CENTRAL E NORDESTE DO BRASIL.
Seamounts are the main topographical features of the oceanic bottom. With a considerable range of heights and top depths, and a variety of substrata and different habitats, constitute important ecosystems. Along the Exclusive Economic Zone (ZEE) of the Central and Northeast coasts of Brazil several oceanic banks and islands exist and are the geographical are
