Modeling sugar cane yield with a process-based model from site to continental scale: uncertainties arising from model structure and parameter values. Author(s): MARIN, F. R. 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. Repository: BDPA Publication year: 2014
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. 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
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. Repository: BDPA Publication year: 2021
Improving crop pest/disease modeling. Author(s): FERNANDES, J. M. C. One of the biggest accomplishments in human history has been the domestication of plants, providing a more continuous food supply and promoting the conformation of sedentary agricultural groups (Pérez... ... Repository: BDPA Publication year: 2019
Model rainfall-runoff in the constraints Amazon. Author(s): ZOLIN, C. 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): MARQUES, J. R. F. 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... ... Repository: BDPA Publication year: 2023
Phenological restriction of the Oryza (v3) model. Author(s): HEINEMANN, A. B.; STONE, L. F.; CUADRA, S. V.; STEINMETZ, S. Photoperiod sensitivity affects the rice development cycle and its flowering. Crop simulation models, such as ORYZA (v3), use equations that depend on two main parameters calibrated by the user: sensi... ... Repository: BDPA Publication year: 2024
Molecular modeling of the riboflavin genes from acidithiobacillus ferrooxidans. Author(s): FALCÃO, P. R. K.; NESHICH, G. 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
Non-destructive models for leaf area determination in canola. Author(s): GOUVEA, J. A. de The leaf is a very important structure of the plants, since it allows gas exchanges and the transformation of light energy into chemical energy. This study aimed to generate and test mathematical mode... ... Repository: BDPA Publication year: 2016
Computer simulation of the coffee leaf miner using sexual Penna aging model. Author(s): ZACARIAS, M. S. Forecast models based on climatic conditions are of great interest in Integrated Pest Management (IPM) programs. The success of these models depends, among other factors, on the knowledge of the tempe... ... Repository: BDPA Publication year: 2008
