Roger's theory of diffusion of innovations and institutional changes in Brazilian rural advisory services. Author(s): PEIXOTO, M.; CASTRO, A. C.; NASCIMENTO, P. P. Rural advisory services (RAS) have played an important role in the Brazilian rural and agricultural development along the last fifty years. Since the sixties Roger?s theory of diffusion of innovations... ... Repository: BDPA Publication year: 2015
Phosphorus diffusion of organomineral fertilizers in samples of sandy soil assessed in Petri plate. Author(s): FONSECA, R. C. da; MATTOS, B. B.; TEIXEIRA, P. C.; CAMPOS, D. V. B. de; STRALIOTTO, R.; BENITES, V. de M.; DONAGEMMA, G. K. Based on the increasing trend in the consumption of granulated organic mineral fertilizers (OMF) in Brazil, it's concluded which the insertion of the product in the domestic market depends mainly on t... ...

Determination of thermal conductivity and thermal diffusivity of papaya (Carica papaya L.) as a function of temperature. Author(s): KUROZAWA, L. E.; EL-AOUAR, A. A.; SIMÕES, M. R.; AZOUBEL, P. M.; MURR, F. E. X. The objective of this paper was to determine the thermal conductivity and the ther mal diffusivity of papaya as a function of temperature using the probe technique. A probe, with a heater wire to appl... ... Repository: BDPA Publication year: 2005
Modeling technology diffusion of beef cattle in Brazil using a cellular automata. Author(s): BRATFISCH, G. G.; BARIONI, L. G.; SILVA, R. de O.; GREGO, C. R.; PEREIRA, B. H.; BERTOLUCCI JUNIOR, J. We introduce a cellular automata model representing the diffusion of technological intensification of beef cattle considering farmer's preferences. We also analyze the theoretical properties of the mo... ... Repository: BDPA Publication year: 2019
Methodology to measure temperature and thermal diffusivity in intact seeds inside soils by time domain NMR. Author(s): CAROSIO, M. G. A.; COLNAGO, L. A. Repository: BDPA Publication year: 2012
Technological circuit as a tool for technological diffusion. Author(s): KATO, H. C. de A.; EVANGELISTA, D. K. R. Repository: BDPA Publication year: 2015
Evaluation of water and sucrose diffusion coefficients during osmotic dehydration of jenipapo (Genipa americana L.). Author(s): ANDRADE, S. A. C.; BARROS NETO, B. de; NÓBREGA, A. C.; AZOUBEL, P. M. The apparent diffusion coefficients for sucrose and water during osmotic dehydration of jenipapos were determined. Long time experiments (up to 60 h) were carried out in order to determine equilibrium... ... Repository: BDPA Publication year: 2007
Prediction of soil physical and chemical properties by visible and near-infrared diffuse reflectance spectroscopy in the Central Amazon. Author(s): PINHEIRO, E. F. M.; CEDDIA, M. B.; CLINGENSMITH, C. M.; GRUNWALD, S.; VASQUES, G. de M. Visible and near-infrared diffuse reflectance spectroscopy (VIS-NIR) has shown levels of accuracy comparable to conventional laboratory methods for estimating soil properties. Soil chemical and physic... ... Repository: BDPA Publication year: 2017
Soil classification from visible/near-infrared diffuse reflectance spectra at multiple depths. Author(s): VASQUES, G. de M.; DEMATTE, J. A. M.; LOPEZ, L. R.; TERRA, F. da S. Abstract : Visible/near-infrared diffuse reflectance spectroscopy (VNIRS) offers an alternative to conventional analytical methods to estimate various soil attributes. However, the use of VNIRS in soi... ... Repository: BDPA Publication year: 2011
