2. Fitossanidade e qualidade de mudas de Eucalyptus urophylla x Eucalyptus grandis em função da aplicação de fosfito e silício
RESUMO O setor florestal é um dos que mais contribui em termos sociais, econômicos e ambientais para o Brasil. Dentro deste setor, a eucaliptocultura pode ser apontada como a mais importante do segmento, com o plantio que representa 5,56 milhões de hectares. A primeira etapa do processo de implantação de florestas de eucaliptos é a produção de mudas,

3. SENSOR SYSTEMS FOR MAPPING SOIL FERTILITY ATTRIBUTES: CHALLENGES, ADVANCES, AND PERSPECTIVES IN BRAZILIAN TROPICAL SOILS
ABSTRACT Soil fertility attributes have different scales and forms of spatial and temporal variations in agricultural fields. Adequate spatiotemporal characterization of these attributes is fundamental to the successful development of strategies for variable rate application of fertilizers, enabling the classic benefits of precision agriculture (PA). Studies

4. Composição granulométrica do filtro ascendente para pós-tratamento de lixiviado de aterro sanitário
RESUMO O lixiviado de aterro sanitário apresenta composição variável e complexa e pode ter elevadas concentrações de nitrogênio amoniacal e matéria orgânica biodegradável e recalcitrante. Devido ao potencial altamente poluidor dos lixiviados estabilizados, além do tratamento biológico convencional, faz-se necessária, em alguns casos, a realizaç

6. FINANCIAL ANALYSIS OF THE INVESTMENT IN PRECISION AGRICULTURE TECHNIQUES ON COTTON CROP
ABSTRACT: The aim of this study was to evaluate a financial analysis by the use of precision agriculture (PA) techniques on cotton crop. The experiment was carried out in a cotton field of 91 ha and its result compared to another field with similar area, cultivated with the conventional agricultural techniques. The financial analysis was extrapolated to the

7. Oral mucosa: an alternative epidermic cell source to develop autologous dermal-epidermal substitutes from diabetic subjects
Abstract Oral mucosa has been highlighted as a suitable source of epidermal cells due to its intrinsic characteristics such as its higher proliferation rate and its obtainability. Diabetic ulcers have a worldwide prevalence that is variable (1%-11%), meanwhile treatment of this has been proven ineffective. Tissue-engineered skin plays an important role in wo

10. Estimating Relative Risk Aversion, Risk-Neutral and Real-World Densities using Brazilian Real Currency Options
Building Risk-Neutral Densities (RND) from options data can provide market-implied expectations about the future behavior of a financial variable. And market expectations on financial variables may influence macroeconomic policy decisions. It can be useful also for corporate and financial institutions decision making. This paper uses the Liu et all (2007) ap

11. A characterization for the flow behavior of as-extruded 7075 aluminum alloy by the improved Arrhenius model with variable parameters
In order to perform the numerical simulations of forging response and establish the processing parameters for as-extruded 7075 aluminum alloy, the compressive deformation behavior of as-extruded 7075 aluminum alloy were investigated at the temperatures of 573 K, 623 K, 673 K and 723 K and the strain rates of 0.01 s-1, 0.1 s-1, 1 s-1 and 10 s-1 on a Gleeble15

12. Definition of management zones in coffee production fields based on apparent soil electrical conductivity
Fertilizer application at variable rates requires dense sampling to determine the resulting field spatial variability. Defining management zones is a technique that facilitates the variable-rate application of agricultural inputs. The apparent electrical conductivity of the soil is an important factor in explaining the variability of soil physical-chemical p
