1. Thermostimulated crystal structure transformation of the polymineral clay submicron particles
Abstract Changes in the structure of phyllosilicate microparticles of submicron fractions of polymineral clay with an average size of 290 nm, as well as changes in the positions of impurity ions of transition metals in the crystal lattice, were studied by X-ray diffraction analysis, Fourier transform infrared spectroscopy, and high-resolution electron parama

2. CLOROFILA EXTRAÍDA DE RESÍDUO INDUSTRIAL DA ERVA-MATE (Ilex paraguaiensis) UMA POSSIBILIDADE DE ECONOMIA CIRCULAR
Chlorophyll is the most abundant green pigment on the planet, it is unstable and decomposes naturally. Mate-herb is a traditional native plant in the southern region of South America, and its tea is part of the local culture and extractive agriculture. The mate-herb industry generates as a by-product a resinous material rich in chlorophyll whose use is propo

3. A New Energetic Complex: Synthesis, Structure, and Combustion Catalysis Performance
The potential of tetrazole-based ligands for forming energetic complexes applied in pyrotechnics and propellants is demonstrated with the use of 5,5’-(1,3-phenylene)bis(1H-tetrazole) (H2BTB) to generate an energetic complex with high energy. A new energetic complex of PbII-tetrazolate, [Pb2(BTB)2(H2O)8]·5H2O (1), was synthesized and structurally character

4. Analysis of the agricultural productivity of the sugarcane crop in regions of new agricultural expansions of sugarcane
Resumo O lançamento dos veículos bicombustíveis, no ano de 2003, propiciou a retomada da importância da produção de etanol e, consequentemente, numa nova fase de expansão do cultivo de cana-de-açúcar no Brasil. Embora o aumento da área de produção e da quantidade produzida de cana-de-açúcar mereça destaque no agronegócio brasileiro, o mesmo

5. Castor polyurethane used as osteosynthesis plates: microstructural and thermal analysis
Abstract Bone fractures to be corrected need stabilization of their extremities, which is achieved with the use of plates and screws. This research aimed to produce castor bean polyurethane (Ricinus communis), to make resorbable plate, structural and thermal analysis. The production was made by the glycerolysis of the triglycerides present in the oil, after

6. The genome sequence of Dyella jiangningensis FCAV SCS01 from a lignocellulose-decomposing microbial consortium metagenome reveals potential for biotechnological applications
Abstract Cellulose and its associated polymers are structural components of the plant cell wall, constituting one of the major sources of carbon and energy in nature. The carbon cycle is dependent on cellulose- and lignin-decomposing microbial communities and their enzymatic systems acting as consortia. These microbial consortia are under constant exploratio

7. Cover Crops Effects on Soil Chemical Properties and Onion Yield
ABSTRACT Cover crops contribute to nutrient cycling and may improve soil chemical properties and, consequently, increase crop yield. The aim of this study was to evaluate cover crop residue decomposition and nutrient release, and the effects of these plants on soil chemical properties and on onion (Allium cepa L.) yield in a no-tillage system. The experiment

8. Comparison of In-Flight Measured and Computed Aeroelastic Damping: Modal Identification Procedures and Modeling Approaches
ABSTRACT The Operational Modal Analysis technique is a methodology very often applied for the identification of dynamic systems when the input signal is unknown. The applied methodology is based on a technique to estimate the Frequency Response Functions and extract the modal parameters using only the structural dynamic response data, without assuming the kn

9. Spatial variation of dung beetle assemblages associated with forest structure in remnants of southern Brazilian Atlantic Forest
ABSTRACT The Brazilian Atlantic Forest is one of the world's biodiversity hotspots, and is currently highly fragmented and disturbed due to human activities. Variation in environmental conditions in the Atlantic Forest can influence the distribution of species, which may show associations with some environmental features. Dung beetles (Coleoptera: Scarabaein

10. Aluminato de lítio : síntese e caracterização morfológica, textural e estrutural
In this work LiAlO2 powders have been synthesized by two different methods: sol-gel and coprecipitation, changing the concentration of reactants and drying process. In the sol-gel process was employed a Al/Li molar ratio equal to 1:1 with controlled drying of the material (SOLLi sample). In the samples synthesized by coprecipitation were employed Al/Li molar

11. Efeitos tecnológicos e estruturais nas emissões brasileiras de CO2 para o período 2000 a 2005: uma abordagem de análise de decomposição estrutural (SDA)
Este artigo objetiva mensurar a influência de mudanças na estrutura produtiva sobre as variações nas emissões de dióxido de carbono brasileiras. O método utilizado foi o de análise de decomposição estrutural (SDA - Structural Decomposition Analysis). Trata-se de um método de insumo-produto, logo de estática comparativa, que permite detalhar as mu

12. Decomposição estrutural da variação do emprego e dos salários no Brasil entre 1990-2007
This study aims to quantify and analyze the main sources of major change in employment and wages between 1990 and 2007 in Brazil through the input-output theory. So to achieve this goal, it is used in this study the methodology of decomposition of structural change in employment and wages for an open economy. In the period 1990 to 2007, the country has under
