Lazer–Leach conditions for coupled Gompertz-like delayed systems
(Pergamon-Elsevier Science Ltd, 2018-09)
A coupled Gompertz-like system of delay differential equations is considered. We prove the existence of T-periodic solutions under resonance assuming a Lazer–Leach type condition.
Deposição de nutrientes na carcaça de girinos de rã-touro
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 2013-08-01)
The objective of this work was to determine nutrient deposition on the carcass of bullfrog (Lithobates catesbeianus) tadpoles using a nonlinear model. A total of 2,700 tadpoles with an average weight of 0.039 g were used. ...
Mathematical modeling of microbial growth in packaged refrigerated orange juice treated with chemical preservatives
(Wiley Blackwell Publishing, Inc, 2001-05)
Microbial flora of refrigerated orange juice was analyzed during storage at 10 8C and the effects of the following factors were discussed: 1) the previous washing process of the orange peel, 2) the different levels of the ...

Description of growth and body composition of freshwater angelfish (Pterophyllum scalare) by Gompertz model
(Revista Brasileira Zootecnia Brazilian Journal Animal Sci, 2017-08-01)
The objective of this study was to describe the growth of freshwater angelfish (Pterophyllum scalare) using the Gompertz model, determining the relative growth and allometric coefficients of body components in relation to ...
Growth and body nutrient deposition of two broiler commercial genetic lines
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2008-06-01)
The objective of this work was to study growth and body nutrient deposition profiles of male and female Cobb and Ross broilers using Gompertz equations. A total number of 1,920 one- to 56-day-old broilers were used. A ...
