Validation of the Streeter-Phelps Model in Matlab to predict biochemical demand for oxygen DOB and dissolved oxygen OD
(Cartagena de Indias, 2020-12-24)
The article intended the validation of the Streeter Phelps mathematical model that describes the behavior of dissolved oxygen OD and the biochemical oxygen demand BOD, which includes re- aeration and deoxygenation processes, ...
Tidally driven sulfidic conditions in Peruvian mangrove sediments
(Springer, 2018)
The seasonal influence of tidal regimes on sulfidic conditions was studied in intertidal environments from a mangrove estuary in Northern Peru. Along two sampling stations, creek water and sediment cores were collected ...
Implementação de sistema nebuloso (“fuzzy”) para controle de oxigênio dissolvido no cultivo de Escherichia coli para expressão de proteínas recombinantes
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2022-04-27)
Due to low oxygen solubility in water and mechanical limitations of a bioreactor, ensuring an adequate dissolved oxygen supply during a recombinant Escherichia coli cultivation is a major challenge in process control. In ...
Development of an electrochemical sensor for determination of dissolved oxygen by nickel-salen polymeric film modified electrode
(Elsevier B.V. Sa, 2012-12-01)
An amperometric oxygen sensor based on a polymeric nickel-salen (salen = N,N'-ethylene bis(salicylideneiminato)) film coated platinum electrode was developed. The sensor was constructed by electropolymerization of nickel-salen ...
Decentralized control with minimum dissolved oxygen guaranties in aerobic fed-batch cultivations
(American Chemical Society, 2013-12)
In this work, a control strategy to guarantee a minimum dissolved oxygen concentration in aerobic fed-batch bioprocesses is proposed. The strategy is equally applicable to avoid low oxygen concentrations that might be ...
Development of a nanocomposite chemiresistor sensor based on Π-conjugated azo polymer and graphene blend for detection of dissolved oxygen
(2018-10-15)
The present paper describes the electrochemical impedance activity of a hybrid film with graphene and poly(azo-Bismarck Brown Y) as the chemiresistor material. This nanocomposite film exhibits interesting properties based ...
