1. Contractual solutions to the holdup problem: a survey
In this survey, we presented the general idea and main results from what we understand that are the most important contributions to contractual solutions to the holdup problem literature. The aim of this paper is to push the previous analysis, uniform the notation and provide a snapshot on the most recent literature, as well as bring topics for future inqui

2. Estudo e desenvolvimento de um extrator de palhetas rotativas
The growth necessity to get higher separation efficiencies in the minimim space has incentivated the researchers to develop new kinds of equipment. The most employed equipment to carry out liquid-liquid extraction processes are the mechanically agitated ones because they provide better performances. Many other types of equipment are presented in literature.

3. "Controle dual de colunas de destilação utilizando I. M. C."
Dual-control of distillation columns is both an operationally important and a technically challenging problem. This work first analyses the reduced-order modeling of binary distillation columns. A basic second-order model was developed and then suitably modified to account for the lag-time due to the plate liquid holdup. This model was then used to implement

4. Continuous Fermentation of Novobiocin
Continuous fermentation trials with Streptomyces niveus in a nine-stage fermentation system (7-liter reaction volume per stage) indicated that the cultures used gradually lost their ability to produce novobiocin when cultured over periods from 10 to 25 days. It was found that mycelial degeneration could be circumvented by operational means during continuous
