1. Performance of crisphead lettuce cultivars under protected environment in different times of production
ABSTRACT The objective of this work was to evaluate the behavior of Crisphead lettuce as a function of production seasons under different forms of protected environment. Two experiments were carried out in the field at different times: September to December 2017 and June to August 2018, in a randomizaed blocks desing, in a 4 x 7 factorial scheme, the first o

2. Physiological and Molecular Responses in Rice, Weedy Rice and Barnyardgrass Exposed to Supra-Optimal Temperatures
RESUMO: A temperatura média global pode aumentar de 0,3 a 4,8 oC até o final do século. Temperaturas supraótimas podem afetar as plantas em diferentes níveis organizacionais, causando alterações morfológicas, fisiológicas, bioquímicas e na expressão de genes, e plantas de arroz, arroz-vermelho e capim-arroz tendem a responder de forma distinta qua

4. Influência de adjuvantes e técnica de enchimento sobre as características farmacêuticas de cápsulas de gelatina dura contendo teofilina / Influence of excipients and filling methodology on pharmaceutical characteristics of hard gelatine capsules containing teophyllin
A produção de cápsulas de gelatina dura em pequena escala pode ser realizada, basicamente, por dois métodos: nivelamento de superfície e pesagem individual. Visando comparar esses dois métodos, bem como avaliar a influência de adjuvantes correntemente utilizados na produção de cápsulas foi realizado um experimento fatorial 23. As respostas analisad

5. Análise da produção do antitumoral retamicina em cultivos contínuos de Streptomyces olindensis ICB20 utilizando planejamento fatorial. / Analysis of the production of the antitumor drug retamycin in continous cultures of Streptomyces olindensis ICB 20 using factorial desing.
The aim of this project was to study the production of retamycin in bench-top bioreactors by Streptomyces olindensis ICB20 in continuous cultures in order to evaluate the influence of the agitation rate (N=300, 500 or 700 rpm), the dissolved oxygen concentration (20%, 50% or 80%) and the specific growth rate (µ=0.05, 0.15 or 0.25 h-¹). A full factorial exp

7. MÃTODOS DE DETERMINAÃÃO E EFEITO DA CONCENTRAÃÃO DE ÃCIDOS FENÃLICOS NA DEGRADABILIDADE DE COASTCROSS / Methods of determination and effects of the concentration of phenolic acids in the coast cross grass degradation
The digestion of the cell wall of forage plants shows closely associatedto its chemical composition.Of the components of cell wall, lignin is considered the one which shows the highest negative effects on ruminal digestion. The concentration of lignin present in the cell was is not enough to account for the variations in the digestion of forages. The arrange

9. Modulation of the lignification process for application of jasmonic acid and 2,4-dichlorophenoxyacetic acid in Eucalyptus urophylla S. T. Blake. / Modulação do processo de lignificação por aplicação de ácido jasmônico e ácido 2,4-diclorofenoxiacético em Eucalyptus urophylla S. T. Blake
Lignin is a important a biomacromolecule for several biologic process in plants, the most important process is to give necessary rigidity to keep the stem verticality, and water and minerals circulation. This research was carried out with Eucalyptus urophylla seedling and the result can help other biothecnological studies. In this research were applied diffe
