Development, essential oil yield and composition of mint species and chemotypes...
Deschamps, Cícero; de Castro, Luciana Witoslawski Piratello; Machado, Marília Pereira; Scheer, Agnes de Paula; Côcco, Lilian CristinaRadiation and soil nutrient levels affect essential oil production in aromatic plants. The objective of this work was to evaluate the vegetative development, essential oil yield and composition of Mentha aquatica L. (linalool chemotype) and Mentha x piperita L. (linalool and menthol chemotypes) cultivated under different radiation levels (100%, 46% and 23%), and with or without nitrogen fertilization. The essen...
Desenvolvimento vegetativo, rendimento e composição do óleo essencial do patcho...
Costa, Andressa Giovannini; Deschamps, Cicero; Côcco, Lilian Cristina; Scheer, Agnes de PaulaNeste trabalho avaliou-se o efeito da aplicação no plantio e na manutenção de diferentes doses de nitrogênio (30, 60, 90 e 120 Kg ha-1) no desenvolvimento do patchouli, bem como no rendimento e composição do óleo essencial. O experimento foi conduzido no município de Joinville-SC, de agosto de 2006 a maio de 2007, com delineamento em blocos ao acaso em parcelas subdivididas no tempo, com cinco repetições. Foram...
Vegetative development and production of essential oil of Patchouli under radia...
Storck, Rafaellen Caroline; Deschamps, Cícero; Côcco, Lílian Cristina; Mógor, Átila Francisco; Scheer, Agnes de Paula; Yamamoto, Carlos ItsuoPogostemon cablin Benth. has economical importance due to the essential oil which is used in the pharmaceutical and perfume industries. Among the environment factors, the radiation is extremely important for plant development and its limitation can result on decrease of yield. The application of gibberellins promotes the cellular elongation resulting on increase of plant height. Therefore, the radiation level a...
Rheological properties of ternary mixtures of yellow fruits - doi: 10.4025/acta...
Haminiuk, Charles Windson Isidoro; Oliveira, Gabriel Alves de; Bona, Evandro; Demczuk Junior, Bogdan; Izidoro, Dayane Rosalyn; Scheer, Agnes de PaulaIn this work, the rheological behaviour of ternary mixtures of orange juice, pineapple and mango pulps was studied using response surface methodology. The flow curves were adequately described by the Herschel–Bulkley rheological model. All the ternary mixtures studied presented a change in the rheological parameters with an increase in temperature, and the majority of the formulations were shear-thinning fluids...
Study of aqueous pectin solutions microfiltration process by ceramic membrane -...
Silva, Vitor Renan da; Scheer, Agnes de PaulaIn this work, pressure effects, separation efficiency and resistive effects of microfiltration of pectin solution were investigated. Stabilized permeate flux values were obtained for solutions concentrations of 1.0 and 2.0 g L-1 under different pressure conditions of 0.4, 0.8, 1.2 and 1.6 bar. A full factorial design with two levels was applied to evaluate the effects of the pressure, temperature and concentrat...
Desenvolvimento de um sistema para simulação e otimização do processo de adsorç...
Scheer, Agnes de PaulaOrientador: Maria Regina Wolf Maciel; Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Engenharia Quimica; Resumo: A adsorção tomou-se nas últimas décadas um processo importante de purificação e separação nas áreas da petroquímica, de alimentos, da química fina e da biotecnologia. É uma operação que pode resolver os sérios problemas dos poluentes diluídos em efluentes líquidos e, também, aquel...
