13. Efficacy of fungal decolorization of a mixture of dyes belonging to different classes
Dyes are the most difficult constituents to remove by conventional biological wastewater treatment. Colored wastewater is mainly eliminated by physical and chemical procedures, which are very expensive and have drawbacks. Therefore, the advantage of using biological processes, such as the biotransformation of dyes, is that they may lead to complete mineraliz

14. Tissue transglutaminase (TG2) activity regulates osteoblast differentiation and mineralization in the SAOS-2 cell line
Tissue transglutaminase (type II, TG2) has long been postulated to directly promote skeletal matrix calcification and play an important role in ossification. However, limited information is available on the expression, function and modulating mechanism of TG2 during osteoblast differentiation and mineralization. To address these issues, we cultured the well-

16. Depósitos auríferos associados ao magmatismo granítico do setor leste da Província de Alta Floresta (MT), Craton Amazônico: tipologia das mineralizações, modelos genéticos e implicações prospectivas / Granitoid-related gold deposits in the Alta Floresta Gold Province (MT), Amazon Craton: ore-forming processes, genetic models and implications to exploration
A Província Aurífera de Alta Floresta, porção centro-sul do Craton Amazônico, localiza-se entre os limites das províncias geocronológicas Ventuari - Tapajós (1,95-1,8 Ga) e Rio Negro - Juruena (1,8-1,55 Ga). Corresponde a uma unidade tectônica essencialmente composta por sequências plutono-vulcânicas geradas em ambiente de arcos magmáticos que se

17. Os Depósitos de Cu-Au-Mo do tipo pórfiro de Bajo de La Alumbrera e Água Rica, Argentina : considerações genéticas sobre formação e fonte de minério
The world-class deposits of Bajo de la Alumbrera and Agua Rica in NW Argentina, are of the Cu-Au-Mo porphyry type (although Agua Rica has some epithermal characteristics). Both deposits are closely related to the activities and formation processes of the Miocene Farallón Negro Volcanic Complex. They are also controlled by the Tucuman Transfer Zone, which is

18. Tratamento de efluente tÃxtil utilizando o processo foto-fenton / Treatment of textile effluent using photo-fenton process
The aim of this work was to study the performance of the photo-Fenton process using both the artificial UV and solar sources on the textile effluent treatments. Preliminary photo-Fenton experiments for mineralization and degradation of organic and inorganic pollutants as well as of synthetic dyes were carried out in order to assess the best experimental cond

19. Interação do alendronato e da vitamina K no metabolismo osteomineral de ratas ovariectomizadas
The bone is a specialized form of connective tissue that provides support for metabolic and biomechanical throughout the body. Thus, the bone is very dynamic, with constantly renewing itself. His integrity therefore depends on the balance between the processes of formation and resorption. The loss of this balance alters both the structure of organic matrix a

20. Structural constraints on Paraná basalt volcanism and their implications on agate geode mineralization (Salto do Jacuí, RS, Brazil)
The Paraná-Etendeka Continental Flood Basalt province hosts world-class agate and amethyst geode deposits in Rio Grande do Sul (Brazil; Serra Geral Fm.). Salto do Jacuí Mining District (Rio Grande do Sul, Brasil) has different types of agate geode hosted in vesicular basalt. A series of structural features has recently been investigated in the Salto do Jac

21. Evolução magmática, alteração hidrotermal e gênese da mineralização de ouro e cobre do Palito, Província Aurífera do Tapajós (PA) / Magmatic evolution, hydrothermal alteration and geneseis of gold-copper mineralization at Palito, Tapajós Gold Province (PA)
The Palito porphyry type copper-gold deposit is located in the central region of the Amazonian craton, in the Tapajós Gold Province (TGP), in an area that is dominated by intermediate to felsic granitic and volcanic rocks of late Paleoproterozoic age. Three lithotypes make up this deposit. The Palito Granite, with porphyritic features, is the host rock for

22. Dioxide carbon emission from different soil tillage in the sugarcane plantation / Emissão de dióxido de carbono após diferentes sistemas de preparo do solo na cultura da cana-de-açúcar
The annual emissions of carbon dioxide (CO2), considered the greenhouse gas (GHG) more important, increased around 80% between 1970 and 2004. This increment mainly due to the use of fossil fuels, and agriculture as emissions from land use change. Land use management is an important tool to GHG emissions decrease. Agricultural soils can be a source or reservo

23. Synthesis of carbonated hydroxyapatite nanorods in liquid crystals
Syntheses of calcium phosphate nanoparticles, carried out in systems formed from surfactant, oil and water, have resulted in materials with promising possibilities for application. The calcium phosphate particles were synthesized using two different liquid crystals, formed from RenexTM, cyclohexane and a salts solution. The morphology of the nanoparticles sy

24. Degradação de benzeno, tolueno e xilenos em águas contaminadas por gasolina, utilizando-se processos foto-Fenton
In this work the potentiality of photo-Fenton processes were investigated toward the degradation of aromatic hydrocarbons (BTXs) from water contaminated with gasoline. The main results demonstrated that BTXs can be quickly degraded by photo-Fenton process assisted by solar or artificial UV-A radiation, degradation that leads to generation of characteristic p
