The present work deals with the removal of Metribuzin from aqueous solutions in a batch and continuous mode using electrosorption technique. This technique is based on the combination of two processes: the adsorption of Metribuzin into activated granular carbon (GAC) column and the application of the electrochemical potential. The effects of various experimental parameters (electrochemical pote...

We propose a computer-aided methodology to automatically generate time optimal production schemes for chemical batch plants operating in multi-batch mode. Our approach is based on the following principles: (1) the plant is modeled at the level of process operations whose behavior is specified by timed automata, (2) the optimal production schemes are generated using algorithms for reachability a...

In this paper we propose a modified framework of support vector machines, called Oblique Support Vector Machines(OSVMs), to improve the capability of classification. The principle of OSVMs is joining an orthogonal vector into weight vector in order to rotate the support hyperplanes. By this way, not only the regularized risk function is revised, but the constrained functions are also modified. ...

Unbleached pulp from the pulp and paper industry was used as a cellulosic material source to produce bioethanol in a separate hydrolysis and fermentation process. In the batch enzymatic saccharification, three cellulolytic enzymes and different initial carbohydrate (CH) contents were tested. Cellic CTec2 was shown to be the most efficient enzyme with the lowest dosage used: 35 FPU gCH . Sugar p...

BACKGROUND Industrial biotechnology that is able to provide environmentally friendly bio-based products has attracted more attention in replacing petroleum-based industries. Currently, most of the carbon sources used for fermentation-based bioprocesses are obtained from agricultural commodities that are used as foodstuff for human beings. Lignocellulose-derived sugars as the non-food, green, an...

We thoroughly examine the experimental batch plant in its two major operation modes: a normal operation mode and a failure operation mode. In order to do so, we use discrete condition/event system as well as timed automata for the specification and the model checking tools SMV, Kronos and HyTech for verification.

conclusions experimental results showed that mcns is an excellent sorbent for removal of mercury ions from petrochemical waste water. in addition, highly complex matrix of this waste does not affect the adsorption capability of mcns. results an effective hg (ii) removal (99.8%) was obtained at ph 6, with 50 mg of mcns for an initial concentration of this ion in petrochemical waste water (5.63 m...

Development of real-time sensor based on the target-specific probe that make possible sensitive, rapid and selective detection and monitoring of the particular antigen molecules could be of substantial importance to the many applications. Because of its high specificity to the target molecules, excellent temperature stability, and easy production, bacterial phage might serve as a powerful biore...

Continuous flow chemistry as a process intensification tool is well known. However, its ability to enable chemists to perform reactions which are not possible in batch is less well studied or understood. Here we present an example, where a new reactivity pattern and extended reaction scope has been achieved by transferring a reaction from batch mode to flow. This new reactivity can be explained...

Ferrites and lossy ceramics, used in HOM (higher order mode) loads for superconducting accelerators, have shortcomings such as poor batch-to-batch reproducibility of electromagnetic properties, extremely low electric conductivity at cryogenic temperatures leading to accumulation of charge on the material surface, brittleness, which may cause contamination of the nearby SRF cavities by lossy dus...
