Análises técnicas e econômicas no sistema de integração lavoura-pecuária submetido à adubação nitrogenada

Sustainable agriculture, reduced production costs and adding value to the system are achieved through the use of agricultural areas throughout the year, in integrated or mixed system. The study aimed to determine the technical coefficients to estimate and evaluate the operational cost and profitability indicators of the consortium of corn with two species of Brachiaria (B. brizantha, MG-5 and B. ruziziensis). The crops were submitted to N rates (0, 100, 200, 300 e 400kg ha-1year-1) at sidedressing, using urea, and winter common bean in succession, in crop-livestock integration under no-tillage, in irrigated conditions, in 2008/2009 agricultural year in Cerrado region (Selvíria - MS). The experiment was conducted in a randomized complete block design with four replications in a 2 x 5factorial. It was concluded thatcathe inputs were the components that most increased the producing cost of corn and common bean in the ILP study. The total operational cost has increased as a function of increasing doses of N. In all treatments the levels of profitability were positive indicating the viability of the system. The treatment that showed the best technical and economic performance was intercropped with corn and B. brizantha, fertilized with 100kg ha-1year-1N and common bean in succession.

Aprendizado de máquina simbólico e técnicas fractais para caracterizar rejeição em biópsia miocárdica

This work combines symbolic machine learning and multiscale fractal techniques to generate models that characterize cellular rejection in myocardial biopsies and that can base a diagnosis support system. The models express the knowledge by the features threshold, fractal dimension, lacunarity, number of clusters, spatial percolation and percolation probability, all obtained with myocardial biopsies processing. Models were evaluated and the most significant was the one generated by the C4.5 algorithm for the features spatial percolation and number of clusters. The result is relevant and contributes to the specialized literature since it determines a standard diagnosis protocol. © 2013 Springer.
