1. Acid matrix production from treated natural vermiculite-hydrobiotite
Abstract Given the potential of acid-activated clays in adsorptive and catalytic processes, several studies focusing on acid matrices have grown over the years, making it possible to study vermiculite, a mineral composed of a type 2:1 unit cell with tetrahedral and octahedral sheets. Therefore, this work aimed to study vermiculite treated with acids for the

2. EXOTIC ARBUSCULAR MYCORRHIZAL FUNGI AND NATIVE DARK SEPTATE ENDOPHYTES ON THE INITIAL GROWTH OF Paspalum millegrana GRASS
RESUMO Os fungos micorrízicos arbusculares (FMA) e os endofíticos “dark septate” (DSE) podem promover o incremento da biomassa vegetal, a depender das condições edafoclimáticas e da interação com a planta hospedeira. O objetivo deste trabalho foi avaliar a interação de fungos micorrízicos arbusculares exóticos e fungos endofíticos DSE nativos

3. Synthesis of Highly Ordered Mesoporous MCM-41: Selective External Functionalization by Time Control
Sol-gel synthesis is commonly used to modify the surface of mesoporous silica nanoparticles (MSN) with organic groups through the co-condensation method. The template removal, and the site-controlled addition of organic groups and their partial occlusion inside the framework walls are still a challenge in the one-pot synthesis. Here, we optimize the synthesi

4. Microbiologically-Influenced Corrosion of 1020 Carbon Steel in Artificial Seawater Using Garlic Oil as Natural Biocide
This work aims evaluate the use of biocides in the microbiologically-influenced corrosion (MIC) of AISI 1020 carbon steel by sulfate-reducing bacteria (SRB) in artificial seawater. A natural biocide (garlic oil) and a commercial biocide (glutaraldehyde) were used to control the corrosion caused by these bacteria in artificial seawater. Microbial growth on th

5. Multi-Attribute Evaluation and Selection of Broiler House for the Low Prevalence of Footpad Lesion
ABSTRACT Intensive broiler production requires large flock density, which compromises litter quality and increases the prevalence of footpad lesions. The present study aimed at comparing the incidence of footpad dermatitis of broilers reared in two different rearing environments. Data from two broiler houses were recorded during 42 d. Air temperature and rel

6. Dinámicas urbanas y transición hacia espacios metropolitanos: el caso de Valdivia y la Región de Los Ríos, Chile
Resumo O processo de urbanização avança rapidamente e afeta várias partes do planeta. Assim, algumas cidades de porte médio começam a mostrar processos de metropolização em seus espaços. No caso do Chile, suas cidades não desconhecem esse processo. E, nesse contexto, este artigo buscou entender a dinâmica de crescimento populacional, variação d

7. Intrinsic Orientation of Hydroxyapatite Grains on the Surface of Dense Pellets Produced by Uniaxial Pressing
Bioceramics synthesized in laboratories must undergo biological tests that consider the final format and all the processing steps involved in the production of the final device. However, in many cases, the synthesized materials are characterized in formats very different from those that will ultimately be implanted into the body. Once living cells are direct

8. Production of components with plaster residue and sodium citrate: physical, mechanical, rheological analysis
Resumo A indústria da construção civil, grande influenciadora no desenvolvimento econômico e social do país, é responsável por um grande consumo de matéria prima e produção de resíduos. O gesso, em especial, apresenta crescimento expressivo, sobretudo na região Nordeste, devido ao Pólo Gesseiro do Araripe. Considerando os graves problemas de seu

9. Biological modulation of corneal epithelial wound healing
RESUMO A transparência e a manutenção da integridade epitelial da córnea são essenciais para suas propriedades ópticas e, para preservar tais características, o epitélio sofre renovação contínua. Essa renovação depende do controle da proliferação e diferenciação celular mediadas por fatores mitogênicos responsáveis pelo aumento das mitoses

10. Controlling sintering and grain growth of nanoceramics
Resumo Sinterização e crescimento de grão são processos fundamentais que afetam a evolução microestrutural das cerâmicas. Os modelos fenomenológicos que descrevem esses processos, conforme encontrados nos livros didáticos, são simplificações do conjunto altamente dinâmico de parâmetros do sistema, o que leva à previsibilidade limitada e à nec

11. Efectos de tratamientos térmicos post-alcalinos sobre las propiedades superficiales de titanio para implantes dentales con diferentes recubrimientos
ABSTRACT Titanium is widely used as dental implant since it is bio-inert and osseointegratable. However, provided that this material cannot induce bone growth from its surface, it is usual to carry out different surface treatments in order to develop bioactive coatings that increase both the initial rate of bone development and the biological anchorage of im

12. Carbon based DLC films: Influence of the processing parameters on the structure and properties
ABSTRACT Hydrogenated carbon-based films, such as DLC (“Diamond Like Carbon”), have interesting properties such as excellent tribological behavior, low friction coefficient, high superficial hardness and good wear resistance; they are chemically inert and highly corrosion resistant. They are deposited by means of PACVD (plasma-assisted chemical vapor dep
