25. Um modelo de duas escalas da resposta elétrica de tecido muscular induzida por ativação de mastócitos / 2-Scales modelling electrical response from muscular tissue induced by mast cells activation.
O estudo dos mecanismos que desencadeiam as reações alérgicas é um tema de grande interesse científico na atualidade. A anafilaxia, reação alérgica sistêmica severa, tem ocupado um lugar de destaque nas pesquisas. Diferentes experimentos em laboratório, tanto in vivo quanto in vitro, assim como diferentes modelos matemáticos baseados nos resultado

26. Study of solar distillation feasibility for treating of oilfield produced water. Doctoral Thesis / Estudo da viabilidade da destilação solar para polimento de águas produzidas de petróleo
Esse trabalho visa estudar a viabilidade da Destilação Solar no polimento de efluentes oleosos: água produzida, de forma a possibilitar o seu reuso na irrigação de culturas oleaginosas ou forrageiras ou ainda na geração de vapor, bem como estudar os fenômenos de transporte envolvidos. A metodologia para desenvolvimento do projeto consistiu em caracte

27. STUDIES ON THE DYNAMICS OF DENSE GRANULAR SYSTEMS / ESTUDOS DA DINÂMICA DE MATERIAIS GRANULARES DENSOS
Granular materials, due to their huge amount of industrial applications (from food industry to astrophysics), have been the object of an increasing number of studies throughout the last couple of decades. Much of the physical description concerning the behaviour of this kind of material, however, still eludes scientists, turning this field of research into a

28. PERCEPÇÃO DOS MORADORES DA VILA MUTIRÃO, REGIÃO NOROESTE DE GOIÂNIA, SOBRE A RELAÇÃO AMBIENTE E SAÚDE
Understanding the factors that influence health has widened its concept, and has contributed to a vision of complexity involving physical, economic, social, cultural, individual and collective aspects, that are interrelated and distributed in time and space, as socio-historically built phenomena. This study examined the relationship between environment and h

29. Análise fotocondutiva de estruturas fotovoltaicas baseadas em TiO2 e poli(3-hexiltiofeno) / Photoconductivity analysis of photovoltaic structures based on TiO2 and poly(3-hexylthiophene)
In this work we investigated electronic transport phenomena in an ITO/TiO2/RRP3HT/Al structure using photoconductivity spectral response when devices were illuminated either by the ITO electrode or by the aluminum. RRP3HT is the regioregular poly(3-hexylthiophene), a polymer that exhibits a relatively strong photovoltaic activity. RRP3HT were dissolved in a

30. Especies locales, mercado y transporte en las investigaciones embriológicas: el estudio de la poliembrionía en armadillos a principios del siglo XX
The article examines the general affirmation that communication networks and mobility are important to science by examining how these factors played a relevant role in one specific case, that is, research on the embryology of certain species of armadillos in the early twentieth century. As we show, access to pregnant females of the species and transport time

31. Solute mass transport simulation in a porous media with CFDs support (Computer Fluid Dynamics). / Simulação de transporte de massa de um soluto em meio poroso com auxílio do CFD (Computer Fluid Dynamics).
With the advance of the personal computers, complex technical problems, before restricted to the huge centers of international researches, have become more accessible by many areas of the knowledge, like the engineering and in particular the Chemical Engineering. Physical phenomena are represented mathematically by differentials equations, which most of the

32. Refino de silício por solidificação direcional. / Silicon refining by directional solidification.
A demanda do silício de grau solar (SiGS) utilizado na indústria fotovoltaica cresce atualmente em uma média de 35% ao ano e a projeção para a próxima década é de constante crescimento. Entretanto, a disponibilidade de matéria-prima para a produção do SiGS não tem crescido na mesma taxa, resultando em uma elevação de seu custo. Logo, a obtenç�

33. NUMERICAL STUDY OF THE INTERACTION BETWEEN A SUPERSONIC JET AND PLANAR SURFACE / ESTUDO NUMÉRICO DA INTERAÇÃO ENTRE UM JATO SUPERSÔNICO E UMA SUPERFÍCIE PLANA
I in this work a study of the interaction between a supersonic jet and a planar surface is presented, with the aim to analyze the behavior of the velocity, pressure and temperature flowfield. This study finds its motivation in the process of thermal spallation of hard rocks, which may result from the interaction between a high pressure and high temperature j

34. Intestinal molecular physiology of Dysdercus peruvianus (Hemiptera) / Fisiologia molecular intestinal de Dysdercus Peruvianus (Hemiptera)
After identification of cathepsins L in vitro assays and in zimograms we began to purify this enzyme in insect midgut. The region V2 was selected as a source of material for purifying a cysteine proteinase because it contains most of the activity of that proteinase. After several attempts to purify this proteinase, an effective process was developed that avo

35. Study of organic light-emitting devices using rare earth and transition metals complexes. / Estudo de dispositivos orgânicos emissores de luz empregando complexos de terras raras e de metais de transição.
This work presents the study of the Rare Earth (RE) and Transition Metals (TM) complexes, as emissive layers of Organic Light-Emitting Devices (OLEDs) designed, built and electro-optically characterized. The thin films were thermally evaporated or spin-coated. This research started with the study of Europium complex changing its central ligand (CL), which sh

36. PROPRIEDADES DE TRANSPORTE DE SISTEMAS NANOSCÓPICOS: ÁTOMOS E MOLÉCULAS / TRANSPORT PROPERTIES OF NANOSCOPIC SYSTEMS: ATOMS AND MOLECULES
In this work we study the electronic transport in atomic and molecular structures. By using the Green´s function method, we address the problem of the electron-electron and electron-phonon interactions and their effects on the conductance of the system. We present a detailed study of the regime where these two interactions are simultaneously important and s
