Modeling sugar cane yield with a process-based model from site to continental scale: uncertainties arising from model structure and parameter values. Author(s): VALADE, A.; CIAIS, P.; VUICHARD, N.; VIOVY, N.; CAUBEL, A.; HUTH, N.; MARIN, F. R.; MARTINÉ, J.-F. This study reveals the spatial and temporal patterns of uncertainty variability for a highly parameterized agro-LSM and calls for more systematic uncertainty analyses of such models.

Effect of study area extent on the potential distribution of Species: A case study with models for Raoiella indica Hirst (Acari: Tenuipalpidae). Author(s): AMARO, G. C.; FIDELIS, E. G.; SILVA, R. S. da; MARCHIORO, C. A. Ecological niche models are used to quantify the relationships between known occurrence records of a given species and environmental variables at these locations. Maxent is among the most widely used... ... Repository: BDPA Publication year: 2023
Care in the evaluation of simulation models. Author(s): LUIZ, A. J. B.; SILVA, F. A. M. da Abstract: The use of simulation models is increasingly frequent in research. The greater capacity, both in memory and processing, as well as the great availability, accessibility and amount of data co... ... Repository: BDPA Publication year: 2024
An analytic representation of the total soil carbon trajectory implied by the general mathematical framework of most soil carbon models. Author(s): STEHLICK, A.; BARIONI, A. E.; BOAS, P. R. V.; BARIONI, L. G. In this work we propose such a representation for the total carbon trajectory whose generality embraces implicitly the mechanism of models as Century, RothC and CQESTR.

Modeling sugarcane development and growth within ECOSMOS .biophysical model. Author(s): COLMANETTI, M. A. A.; CUADRA, S. V.; LAMPARELLI, R. A. C.; CABRAL, O. M. R.; VICTORIA, D. de C.; MONTEIRO, J. E. B. de A.; FREITAS, H. C. de; GALDOS, M. V.; MARAFON, A. C.; ANDRADE JUNIOR, A. S. de; SILVA, S. D. dos A. e; BUFON, V. B.; HERNANDES, T. A. D.; MAIRE, G. LE Sugarcane plays an important role in electricity and sugar production and is a viable biofuel. Developing and optimizing a mechanism that can predict crop growth and yield at different spatiotemporal... ... Repository: BDPA Publication year: 2024
Model rainfall-runoff in the constraints Amazon. Author(s): CASAVECCHIA, B. H.; ALMEIDA, F. T. de; SOUZA, A. P. de; ZOLIN, C. A.; ULIANA, E. M.; MARQUES, A. The development of a hydrological model in Amazon region has been a challenge for researchers since historical series of hydrological data in the Amazon region are still insufficient. The aim of this... ... Repository: BDPA Publication year: 2018
Growth curve mixed nonlinear models in quails. Author(s): CAMARGO JÚNIOR, R. N. C.; ARAÚJO, C. V. de; MENEZES, F. L. de; ARAÚJO, S. I.; PAVAN, N. L.; ROCHA-SILVA, M.; SILVA, W. C. da; MARQUES, J. R. F.; SILVA, A. G. M. e; CHALKIDIS, H. de M.; LOURENÇO JÚNIOR, J. de B. Our aim was to evaluate the use and application of different nonlinear mixed models, as well as to compare them with approach in nonlinear fixed models, for describing the growth curve of meat-type qu... ...

Molecular modeling of the riboflavin genes from acidithiobacillus ferrooxidans. Author(s): FERRAZ, L. F. C.; REIS, F. de C.; SANTOS, M. T.; FELÍCIO, A. P.; FALCÃO, P. R. K.; NOVO, M. T. M.; NESHICH, G.; GARCIA JUNIOR, O.; OTTOBONI, L. M. M. Short Abstract: Acidithiobacillus ferrooxidans is a bacteria with economic relevance in metal bioleaching. Very little is known about the riboflavin genes from Acidithiobacillus ferrooxidans. Molecula... ... Repository: BDPA Publication year: 2006
Modelling eucalyptus biomass production at regional scale in Brazil. Author(s): ATTIA, A.; CUADRA, S. V.; NOUVELLON, Y.; GUILLEMOT, J.; CAMPOE, O. C.; CABRAL, O. M. R.; LACLAU, J.; GALDOS, M.; LAMPARELLI, R.; Le MAIRE, G. Among forest vegetation grown in Brazil, Eucalyptus is the most widely planted tropicalhardwood genus covering approximately 5.7 million ha for an average yield of 49 m3 ha-1 yr-1.Wide differences of... ...
