Study of the biodiesel B100 oxidative stability in mixture with antioxidants
Elaine Cristina Rodrigues Maia,Dionísio Borsato,Ivanira Moreira,Kelly Roberta Spacino,Paulo Rogério Pinto Rodrigues,André Lazarin Gallina +5 more
TL;DR: In this article, the authors assessed the oxidative stability of biodiesel B100, made from soybeans, in the presence of three synthetic antioxidants, butylhydroxyanisole (BHA), terbutylhydroquinone (TBHQ), pure or in mixture, from the simplex-centroid design.

Dionísio Borsato,João Rafael de Moraes Cini,Hágata Cremasco da Silva,Rodolfo Lopes Coppo,Karina Gomes Angilelli,Ivanira Moreira,Elaine Cristina Rodrigues Maia +6 more
TL;DR: In this article, the authors evaluated the oxidative stability of B100 biodiesel from soybean oil with the addition of three synthetic antioxidants, butylhydroxyanisole (BHA), tertbutyl-hydroquinone (TBHQ), either pure or mixed, according to the simplex-centroid mixture design.

Relative protection factor optimisation of natural antioxidants in biodiesel B100
Kelly Roberta Spacino,Elisangela Tavares da Silva,Karina Gomes Angilelli,Ivanira Moreira,Olívio Fernandes Galão,Dionísio Borsato +5 more
TL;DR: In this paper, alcoholic extracts of natural antioxidants rosemary, oregano and basil were used to evaluate the protection factor in biodiesel, and the analysis of total phenolics content of the extracts showed that the highest values were found for rosemary extract, followed by oreganos and basil.

Aplicação do delineamento simplex-centroide no estudo da cinética da oxidação de biodiesel B100 em mistura com antioxidantes sintéticos
Dionísio Borsato,Luiz Henrique Dall'Antonia,Carmen Luisa Barbosa Guedes,Elaine Cristina Rodrigues Maia,Heverson Renan de Freitas,Ivanira Moreira,Kelly Roberta Spacino +6 more
TL;DR: In this paper, the authors evaluated the oxidative stability of B100 biodiesel from soybean oil in the presence of three commercial synthetic antioxidants, butylated hydroxyanisole (BHA), BHT and tert-butylhydroquinone (TBHQ), pure or blended, from the experimental design of simplex-centroid mixture.
Saline distribution during multicomponent salting in pre-cooked quail eggs
Dionísio Borsato,Mariete Barbosa Moreira,Ivanira Moreira,Marcos Vinicios Roberto Pina,Rui Sérgio dos Santos Ferreira da Silva,Evandro Bona +5 more
TL;DR: In this article, the diffusion that occurs during quail egg salting in static and stirred brine was simulated using a generalization of the Fick's 2 nd law, and the COMSOL Multiphysics software was used to simulate the diffusion in the NaCl-KClwater system.
