ONLINE PROCESS STATE ESTIMATION FOR HANSENULA POLYMORPHA CULTIVATION WITH 2D FLUORESCENCE SPECTRA-BASED CHEMOMETRIC MODEL CALIBRATED FROM A THEORETICAL MODEL IN PLACE OF OFFLINE MEASUREMENTS

The use of 2D fluorescence spectra is a powerful, instantaneous, and highly accurate method to estimate the state of bioprocesses.The conventional approach for calibrating a chemometric model from raw spectra needs a large number of offline measurements from numerous runs, which is tedious, time-consuming, and error-prone.In addition, many process

Abstract Protein preconcentration is an essential sample preparation step for analysis in which the targeted proteins exist in low concentrations, such as bodily fluids, water, or wastewater.Nonetheless, very few practical implementations Glandulars of miniaturized protein preconcentration devices have been demonstrated in practice, and even fewer

The boiler economizer is a tube heat exchanger located in the final part of the convective Flower Shadow Box With LED Light duct.In the economizer, water flowing into the boiler is preheated by flue gases.The paper presents the boiler economizer mathematical model with distributed parameters, which can be used to simulate its operation.The develope

Graphene-based devices have important applications attributed to their superior performance and flexible tunability in practice.In this paper, a new kind of absorber with monolayer graphene sandwiched between two layers of dielectric rings is proposed.Two peaks with almost complete absorption are realized.The mechanism is that the double-layer diel

A method that allows calculating the primary energy savings of fuel Part Package cogeneration of electricity and heat as compared to separate methods produce the same amount of these types of energy.An analytic expression relating the energy consumption of fuel for production of electricity and heat, taking into account the efficiency with the tech
