2. Influence of Vegetation on the Outdoor-to-Indoor Mobile Radio Propagation in 700 MHz Band
Abstract Starting from outdoor transmission, crossing vegetation, the wideband and narrowband characterization of the indoor mobile radio channel in the 700 MHz band is obtained from experiments carried out in the indoor environment of the Engineering building at Fluminense Federal University, and from the processed data, respectively, the power-delay profil

3. Comportamiento termico-energético de una vivienda social de la ciudad de Mendoza, Argentina
The state provides 30% of houses per year in the city of Mendoza. This study evaluates: (a) the thermal-energy quality of a social house, through in-situ measurements under conditions of actual use; (b) needed energy requirements through a balance; (c) a simulation of the house using the SIMEDIF program, in which the model was adjusted, and some easy to impl

4. Simulação energética para análise da arquitetura de edifícios de escritório além da comprovação de conformidade com códigos de desempenho / Building performance simulation for analysis of the architecture of office buildings beyond code compliance checking
No Brasil e em São Paulo, a ASHRAE Standard 90.1 Energy Standard for Buildings Except Low-Rise Residential Buildings ganhou rápida aceitação nos últimos anos. A norma é referenciada pelo sistema de certificação Leadership in Energy and Environmental Design - LEED para estabelecer padrões mínimos de desempenho energético. Apesar do desenvolvimento

5. Method to reduce soiling deposition on building envelope. / Método para redução de mancha nas vedações externas de edifícios.
Building roofs and façades usually show blackening surfaces after few years in large cities. On porous and silicious materials those soiling is caused by particles pollution depositions and mould growth, and the available methods available to prevent this phenomenum do not have a good performance along its service life. This thesis, based on an intensive la

6. Absortancia solar de superficies opacas : metodos de determminação e base de dados para tintas latex acrilica e PVA / Solar absorptance of opaque surfaces : a determination methods and data base for latex acrylic and PVA coatings
Solar radiation is the main responsible factor for the thermal load of buildings, and its impact over this load depends, mainly, on the solar absorptance of the building envelope. The lack of reliable and current data implies that researchers and specialists use visual perception or adopt tables based on surface colors to quantify the solar absorptance, whic

7. The solar envelope and the right to the sun / O envelope solar e o direito ao sol
This work presents a study that investigates forms of regulation of access to the sun and its qualification, in the processes of urban planning and project of the building. Given the great availability of sun and natural light in the country, this regulation becomes recommendable. With the spread of the knowledge about the solar envelope and the introduction

8. Técnicas de incorporação de controle de acesso à luz solar em modelos computacionais de edificações / Technques for integrating sunlight access control to computer models of buildings
Os benefícios obtidos com a disponibilidade de radiação solar dentro ou ao redor dos edifícios são fundamentais no planejamento urbano e provocam significativo impacto sobre o uso do solo, densidade de construção, valorização do solo urbano, conforto térmico e economia de energia. CityZoom é um ambiente computacional de apoio à decisão em projet

9. Thermal performace of glasses in building construction: study in test-cells / Desempenho termico de vidros utilizados na construção civil : estudo em celulas-teste
Thermal performance of buildings depends on several factors, such as implantation, orientation, materials and building components, which should be appropriately defined for different climate conditions. The building acts as a controller of the climatic variables, through the building envelope (walls, floor, roof and openings) and the nearby elements. Buildin

10. Coupled tridimensional heat and moisture transfer in soils under buildings / Transferência tridimensional acoplada de calor e de umidade em solos sob edificações
After the wide world crisis of energy in the 70#s and the interest in energy consumption reduction, some computational programs had been developed to simulate the building energy performance. However, these codes present some simplifications on their calculation routines of heat transfer through the ground. In this way, we have described a mathematical model

11. Ran GTPase Cycle and Importins α and β Are Essential for Spindle Formation and Nuclear Envelope Assembly in Living Caenorhabditis elegans EmbryosV⃞
The small GTPase Ran has been found to play pivotal roles in several aspects of cell function. We have investigated the role of the Ran GTPase cycle in spindle formation and nuclear envelope assembly in dividing Caenorhabditis elegans embryos in real time. We found that Ran and its cofactors RanBP2, RanGAP, and RCC1 are all essential for reformation of the n

12. Sizing up the nucleus: nuclear shape, size and nuclear-envelope assembly
The nucleus is one of the most prominent cellular organelles, yet surprisingly little is known about how it is formed, what determines its shape and what defines its size. As the nuclear envelope (NE) disassembles in each and every cell cycle in metazoans, the process of rebuilding the nucleus is crucial for proper development and cell proliferation. In
