As a consequence, [Formula: see text] dissociation equilibria arise in fermenters by the growing culture. Anaplerotic reactions make use of the abundant [Formula: see text] levels for refueling citric acid cycle demands and for enabling oxaloacetate-derived products. At the same time, CO2 is released manifold in metabolic reactions via decarboxylation activity. The levels of extracellular [Formula: see text] depend on cellular activities and physical constraints such as hydrostatic pressures, aeration, and the efficiency of mixing in large-scale bioreactors. Besides, local [Formula: see text] levels might also act as metabolic inhibitors or transcriptional effectors triggering regulatory events inside the cells. This review gives an overview about fundamental physicochemical properties of [Formula: see text] in microbial and mammalian cultures effecting cellular physiology, production processes, metabolic activity, and transcriptional regulation.Reducing distortions caused by the welding process using different shielding strategiesProduction Engineering Vol. 10 (2003)2, S. 35-40.

Reducing distortions caused by the welding process using different shielding strategiesProduction Engineering Vol. 10 (2003)2, S. 35-40.2003Arc Automation, ISW Laser Process, Production Sensor Welding Most sensors for welding automation work very well for seam tracking, on the other hand, thereis the control of the welding process. For this, optical sensors are the best choice becausethey are able to provide the complete groove geometry. Naturally arc welding and opticalsensors combined causes distortions in the sensor signal. Different methods for reducing thesekinds of distortions will be presented. Optical laser-sensors have also problems withreflective metallic surfaces that cause secondary reflections. Beginning with mechanicalshielding, different mechanical constructions, shielding device and parameters areinvestigated. Optical shielding was analyzed as well as the use of different lasers and thevariation of optical band-pass filters. Additionally to band-pass filters, the use of opticalpolarizer was investigated in reduction of secondary reflections. The reflections can not bereduced by optical or mechanical shielding, therefore, new image processing algorithms have tobe investigated. For further development in digital filter algorithm mathematical models ofreflections were applied to real reflection distorted frames.
