1. Fair Value of Biological Assets: An Interdisciplinary Methodological Proposal
Resumo Dada a complexidade de se mensurar o fair value de ativos biológicos agrícolas, que geralmente não possuem um mercado ativo e são dependentes de fatores climáticos, ambientais e biológicos, surge a necessidade de uma visão interdisciplinar que considere outros inputs além dos econômicos e contábeis. Nesse sentido, o presente ensaio teórico

2. SPATIAL CORRELATION OF SOYBEAN PRODUCTIVITY, ENHANCED VEGETATION INDEX (EVI) AND AGROMETEOROLOGICAL VARIABLES
ABSTRACT The survey information from growing regions, the interaction with the vegetation index and climatic variables is of great importance in the search for soybean productivity increase. Paraná is the second largest soybean producer in Brazil and presents great spatial variability, both in periods of the crop cycle as in soil and climate. The objective

4. Sugarcane crop efficiency in two growing seasons in São Paulo State, Brazil.
A conceptual framework for crop production efficiency was derived using thermodynamic efficiency concept, in order to generate a tool for performance evaluation of agricultural systems and to quantify the interference of determining factors on this performance. In Thermodynamics, efficiency is the ratio between the output and input of energy. To establish th

5. Integrating time series mining and fractals to discover patterns and extreme events in climate and remote sensing databases.
This thesis presents new methods based on fractal theory and data mining techniques to support agricultural monitoring in regional scale, specifically regions with sugar cane fields. This commodity greatly contributes to the Brazilian economy since it is a viable alternative to replace fossil fuels. Since climate influences the national agricultural producti

6. Eficiência da área de sombreamento artificial no bem-estar de novilhas leiteiras criadas a pasto / Artificial shadow area efficiency in milk heifers welfare in pastures
This study had as objective to evaluate and quantify the effect of artificial shading proportioned by different shadow areas under physiology and behavior of milk heifers, in pastures. Research was realized in the period from February to April, 2008. Experimental area was divided in 20 adjacent parcels with 84m2 to treatments 1, 2 and 3 and with 70m2 to trea

7. Mudanças climáticas e a expectativa de seus impactos na cultura da cana-de-açúcar na região de Piracicaba, SP / Climate changes and their expected impacts on the sugarcane crop in the Piracicaba region, state of São Paulo, Brazil
Recent studies show increasingly higher concentrations of greenhouse effect gases in the atmosphere since the Industrial Revolution. The major responsibility for the global warming is attributed to such increase, caused by gases resulting mainly from anthropic activities like burning fossil combustibles and deforestation. Other than temperature, precipitatio

9. Sistema de suporte à tomada de decisão para o manejo fitossanitário nos Campos Gerais do Paraná
Climate factors influence the occurrence of plant diseases. The objective of this work was to develop a decision support system for plant disease management and control, through the monitoring of the climatic variations and determine the risk of occurrence of plant diseases epidemics. For the decision support system a software was developed (Arc-Epidemic - A
