the steps taken in designing a loop reactor for bulk propylene polymerization are discussed. the roles played by several parameters like particle growth factor, catalyst activity and solid fraction on reactor volume at different operating conditions are investigated. at first, based on a fixed production capacity and specific rate of catalyst, reactor volume is determined. next, the length and ...

Generation of test benches for large DSP behavioral models is a complicated, labor intensive task. Also, tests generated manually satisfy no formal definition of completeness. To address these needs, high level approaches to test bench development are employed which relieve the modeler of the details of this task. CASE tools are used to develop the test bench VHDL code, i.e., state machine beha...

The presented investigation focuses on the development of a novel microgap reactor concept for photocatalytic degradation micropollutants from aqueous solutions with titanium dioxide-based catalysts immobilized by spray coating. Combinatorial experiment designs were utilized in order to study influence width, irradiance and catalyst layer thickness conversion 17 ?-ethinyl estradiol. impact cata...

Die Aufgabe der Arbeitsgruppe Medizinische Physik in diesem Projekt ist es, die Sicht der Anwender bzw. der Applikation zu vertreten, um die Praxistauglichkeit der Ergebnisse sicherzustellen. Dazu stellt die Arbeitsgruppe ein Framework zur Algorithmenentwicklung der digitalen Audio-Signalverarbeitung unter MATLAB zur Verfügung, welches die Kommunikation zu den Tools zur Verlustleitungsabschätzu...

An efficient two-step enzymatic process for production of (R)- and (S)-ethyl-3-hydroxybutyrate (HEB), two important chiral intermediates for the pharmaceutical market, was developed and scaled-up to a multikilogram scale. Both enantiomers were obtained at 99% chemical purity and over 96% enantiomeric excess, with a total process yield of 73%. The first reaction involved a solvent-free acetylati...

OBJECTIVE Although several inanimate bench models have been described for training of suture skills, so far, there is no ideal method for teaching and learning this skill during medical education. The aim was to evaluate whether bench model fidelity interferes in the acquisition of suture skills by novice medical students. METHODS 36 medical students with no surgical skills' background (novic...
