1. History of development of thermoelectric materials for electric power generation and criteria of their quality
An analysis of results, obtained in the development of thermoelectric materials for electricity generation during the last 130 years, shows that they are comparable to those obtained as early as the nineteenth century. One of the main factors responsible for the stagnation in this area is the use of inappropriate criteria for the evaluation of material quali

2. Por dentro da Gaiola de Faraday: estudos e ideias sobre a estrutura da matéria (1836-1838)
This research deals with experimental practices developed by Michael Faraday, held from 1836 until early 1838, focusing mainly on the experiment, which would later be known as the "Faraday cage". We analyzed the Experimental Researches in Electricity (ERE), in which are recorded reflections and experiments that were subsequently presented to the Royal Societ

5. Os estudos de Joseph Priestley (1733-1804) sobre a teoria da eletricidade
Nesta tese abordamos alguns aspectos relacionados ao processo investigativo de Joseph Priestley (1733-1804) sobre a teoria da eletricidade, a saber, a teoria dos dois fluidos elétricos. Priestley foi um dos filósofos naturais que realizou inúmeros experimentos a fim de verificar a existência da eletricidade em diversos materiais. Seus experimentos foram

8. Influência do projeto hidrelétrico de Corumbá IV sobre a gestão ambiental municipal / Influência do projeto hidrelétrico de Corumbá IV sobre a gestão ambiental municipal
Large infrastructure projects can generate impacts on the development of a specific area or region, creating economic conditions that attract other projects and multi-sectional operations. These projects are developed according to a predetermined schedule, guided by the mandates of particular programs, plans and policies. Moreover, these projects become impo

9. A historical study of the evolution of vector potential in classical electromagnetic theory / Um estudo histórico da evolução do conceito de potencial vetor no eletromagnetismo clássico
Currently the vector potential generally is considered in the classical electromagnetic theory as an artifice for the calculation of the electric and magnetic fields and without a clear physical meaning. However, when it was proposed in the mid-nineteenth century, it used to have a clear physical meaning and played a central role for Faraday, Maxwell and oth
