1. Reabilitação térmica: Contributo das argamassas com incorporação de material de mudança de fase
RESUMO O setor residencial encontra-se muitas vezes envelhecido, apresentando necessidades de intervenções urgen-tes. Assim, torna-se importante reabilitar edifícios do ponto de vista estrutural, estético e funcional. A reabili-tação térmica é uma importante oportunidade para atingir níveis mais elevados de desempenho energético, reduzindo a elevad

2. Modeling the Local Viscoelastic Behavior of Living Cells Under Nanoindentation Tests
Abstract Aiming at multiscale numerical investigations of fibrous connective tissues, the present work proposes a finite strain viscoelastic model suitable to represent the local mechanical response of living cells in conjunction with finite element simulations of nanoindentation tests. The material model is formulated in a thermodynamically consistent frame

3. Investimento parental e papéis sexuais em opiliões com cuidado paternal exclusivo / Parental investment and sex roles in harvestmen with exclusive paternal care
Exclusive paternal care is the rarest form of post-zygotic parental investment in nature, which has independently evolved in no more than 14 arthropod lineages. Although many of those species are easily observed and manipulated, only recently researchers have started to pay attention and test hypotheses on parental investment and evolution of sex roles in su

4. Análise da influência de variáveis operacionais de um sistema de trigeração sobre o desempenho termodinâmico e a distribuição das utilidades / Analysis of operational variables in a trigeneration system and their influence over thermodynamic performance and distribution of utilities
In this work a trigeneration system, simultaneous production of power, heat and cooling using only one energy source, was analyzed, aiming at a better energetic efficiency of the system, showing the influence of some operating variables of the process on the utilities generated and the efficiency of the overall system. In this study the influence of the comp

5. Quantum effects in water: proton kinetic energy maxima in stable and supercooled liquid
A strong temperature dependence of proton mean kinetic energy was observed for liquid water around the density maximum and for moderately supercooled water. Line shape analysis of proton momentum distribution, determined from deep inelastic neutron scattering measurements, shows that there are two proton kinetic energy maxima, one at the same temperature of

6. Envolvimento dos quatro genes bZIPs do Grupo C de Arabidopsis thaliana na sinalização por glicose, manose e ABA / Functional analysis of the Arabidopsis Group C bZIPs homologous to the maize Opaque-2 regulator
In the model eudicot organism A. thaliana (Arabidopsis), four genes encoding bZIP transcription regulatory factors that are homologous to the maize Opaque-2 (O2) locus were identified. O2 is a key regulator of the carbon to nitrogen balance and of the prolamine type storage proteins synthesis during seed development. The Arabidopsis genes, AtbZIP9, the two p

7. Avaliação da Sustentabilidade do Biodiesel de Soja no Brasil
Biodiesel production in Brazil is currently being sustained mainly by soybean cultivation, mixed with methanol. There is a discussion about the possibility of this soybean-based production can contribute to develop the country in a sustainable manner, taking into account social, economic, environmental and strategic aspects. On the other hand, all those rela

8. SEMI-EMPIRICAL SIMULATION OF THERMOLUMINESCENT RESPONSE UNDER DIFFERENT FILTER GEOMETRIES / "Simulação semi-empírica da resposta termoluminescente sob diferentes geometrias de filtro"
Many thermoluminescent materials has been developed and used for photon personal dosimetry but no one has all desired characteristics alone. These characteristics include robustness, high sensitivity, energy photon independence, large range of photon energy detection, good reproductibility, small fading and simple glow curve with peaks above 150oC. Calcium S

9. Propagação de Campos Eletromagnéticos em Meios Materiais Finitos
In this thesis, the electromagnetism in material media is considered. It starts from the Macroscopic Maxwell Equations assuming that the fields have a temporal dependence that can be expressed by a Fourier transform. The conservation of the energy, linear momentum and angular momentum are studied from a general point of view. By taking the temporal average o

11. Um Estudo de Politicas e Práticas do uso do GNV no transporte público urbano do Brasil / A study on policies and practices concerning the use of natural gas vehicle for the urban public transport in Brazil
The use of Natural Gas Vehicle has had a fast increase lately. However, in order to have a continuous success this Program needs to develop converting devices of Otto-cycle engines, gasoline or alcohol, to the use of NGV (Natural Gas Vehicle) that presents low cost, maintaining the same original development of the vehicle and low level of emissions, consider

12. Socioeconomic, nutritional and antioxidants profile in young smokers from the city of Viçosa MG / Perfil socioeconômico, nutricional e de antioxidantes de jovens fumantes, do município de Viçosa-MG
With the objective of comparing the socioeconomic, nutritional and antioxidant profile of young smoking and non smoking subjects, a controlled transversal study was conducted. Smokers and non smokers were selected from educational institutions from the city of Viçosa MG. It was considered as smoker the individual that smoked at least one cigarette daily, fo
