http://www.naun.org/journals/m3as/2008.htm, We propose a new perspective on the identification of linear dynamic system using structural similarity. The proposal consists in the meaningful exploration of each model, specifically behavior of the state variable.
The decomposition of the behavior of a state…

and (ii) the derived state of the breeding (rather than winter) ecological niches of each species., The evolution of migration has long been considered complex and recent work has demonstrated additional complexity: some species follow the same ecological conditions throughout…

There has been a lot of research addressing the relationship between Information Technology (IT) investments and
productivity. Most of the work has been based on firm-level metrics such as total IT investment. We present what
we believe is…

The combination of soil science, forestry, agronomy and biology allowed an analytical comparison of various experimental mixed culture systems. From these studies, a descriptor system was developed which allows to understand the contribution of each plant species to nutrient cycling,…

Neste trabalho discutimos percepções e práticas de moradores e
produtores, e expressões destas, e também percepções sobre as intervenções de
organizações públicas, civis e de empresas agropecuárias e ambientais, sobre
usos e cuidados com os recursos naturais, em especial a…

The object of this work was to verify the utility of a level IV fugacity model to simulate the environmental fate of the insecticide carbofuran when employed in the cultivation of irrigated rice. The model simulated the dynamic distribution of…

O conhecimento sobre a resposta das forrageiras aos distúrbios antrópicos e naturais é fundamental para auxiliar os tomadores de decisão na avaliação da condição de conservação e tendência das pastagens nativas ou no desenvolvimento de estratégias adequadas de manejo adaptativas.…

Reverse logistics activities require the ability to generate new knowledge to reduce high uncertainty and to solve problems resulting of these activities. In this sense the purpose of this research is to understand how the modes of knowledge conversion (Nonaka…

Knowledge of the distribution of soil organic matter (SOM) fractions is important in managing soils toward a sustainable agricultural system ina tropical environment, However, data on Histosols in limited. This study developed 19 regions of Brazil. Soil organic matter was…
