1. The influence of compositional variability of dimension stone residues on the properties of rustic porous ceramic tiles
Abstract This study analyzed how the compositional variability of dimension stone residues influences the characteristics of rustic porous ceramic tiles. The specimens were prepared by adding 20 wt% of dimension stone residue to the clay and sintered at 1000 °C for 1 h. The testing assays performed were physical properties and structural analysis through sc

2. Technical dossier and legal proceedings in Brazilian dimension stone mining
Abstract This article presents a guide to be followed by mining companies willing to open a dimension stone quarry in Brazilian territory. It highlights the main technical documents required by Federal legislation to obtain mining authorization. These documents and their singularities were compiled based on a study of Brazilian mining laws, other normative i

3. Analysis of Dimension Stone Waste Addition to the Clayey Mass Used in Roof Tile Production
Addition of dimension stone waste to clayey mass is an alternative to make the dimension stone sector more environmentally sustainable and to reduce the consumption of clayey raw material. Our aim is to study the technical feasibility of dimension stone waste addition to the clayey mass used in roof tile production. Samples of waste and clay were tested for

4. Análise comparativa da aderência de tipos rochosos assentados com três argamassas / Comparative analysis of adherence of stone types seated with three mortars
O presente estudo trata da determinação da resistência de aderência de três rochas: arenito, mármore e quartzito assentados com três diferentes argamassas (industrializada, resíduo e para porcelanato). Os ensaios de resistência de aderência à tração foram executados tanto na face lisa como na não polida (natural) dos corpos de prova e seguiram

5. Visões de proteção social e transferência de renda condicionadas no Brasil e no México
This work analyses the Visions of Social Protection (VSP) related to Conditioned Cash Transfers (CCT) in Brasil and Mexico, Programa Bolsa Família (Family Grant Program) and Programa Oportunidades (Opportunities Program), respectively. The aim is to investigate the symbolic dimension of the public policies process, theme almost unexplored in Brazil, through

6. The time-dependent Schrödinger equation: the need for the Hamiltonian to be self-adjoint
We present some simple arguments to show that quantum mechanics operators are required to be self-adjoint. We emphasize that the very definition of a self-adjoint operator includes the prescription of a certain domain of the operator. We then use these concepts to revisit the solutions of the time-dependent Schroedinger equation of some well-known simple pro

7. Home and way in the Mỹky origin myth: for an ethical and esthetically intercultural curriculum / Casa e caminho no mito de origem Mỹky: por um currículo ética e esteticamente intercultural
This study is about the urgency of an ethical and aesthetically mindful School for the humans who compose it. Its based on the indigenous myth of The Stone Home, of the Mỹky people. In this myth, House and Way appear like archetypes that intertwine themselves with the stillness and the wager, as whos dreaming of Walking from the Home to the hope that w

8. Relation between sawing process and quality of sawed surfaces of ornamental granites / Relação entre processo de corte e qualidade de superfícies serradas de granitos ornamentais
The industry of ornamental and dimension stone can be improved by the global and integrated overview of stone properties and performance machines, equipment and insums. Although with excellent growth in production and exportation and great technological advance, the empirism predominates in the productive process, a practice that might leads to loses, failur

9. Condutividade térmica de rochas: uma aplicação para granitos ornamentais
This dissertation focuses on rock thermal conductivity and its correlations with petrographic, textural, and geochemical aspects, especially in granite rocks. It aims at demonstrating the relations of these variables in an attempt to enlighten the behavior of thermal effect on rocks. Results can be useful for several applications, such as understanding and c

10. Estudo sobre o revestimento de fachadas de edifícios altos com placas de granitos ornamentais / Study on exterior dimension stone cladding systems with ornamental granites
O Brasil, no mercado mundial, ocupa lugar de destaque na extração e comercialização das rochas ornamentais e de revestimento, demonstrado pela produção mensal de chapas que é da ordem de 4 milhões de metros quadrados. Dentre suas as diversas formas de aplicações na construção civil, observa-se um incremento do uso em revestimentos de fachadas de

12. Avaliação da recuperação de áreas degradadas por mineração na região metropolitana de São Paulo. / Rehabilitation of degraded areas in metropolitan region of São Paulo, Brazil.
This work deals with the assessment of mine reclamation procedures in the Sao Paulo Metropolitan Region (RMSP). It begin with the presentation of the problem and of the hypothesis which orientated the research work. The very incipient character of the reclamation works is emphazised as well its potential role in urban areas (Chapter 1). Chapter 2 describes t
