Nowadays, high-throughput screening is essential for determining the best microbial strains and fermentation conditions. Although microtiter plates allow higher throughput in screening than shake flasks, they do not guarantee sufficient oxygen supply if operated at unsuitable conditions. This is especially the case in viscous fermentations, potentially(More)
BACKGROUND Pretreated lignocellulosic biomass is considered as a suitable feedstock for the sustainable production of chemicals. However, the recalcitrant nature of cellulose often results in very cost-intensive overall production processes. A promising concept to reduce the costs is consolidated bioprocessing, which integrates in a single step cellulase(More)
3D biodegradable materials (scaffolds) containing bioactive hydroxyapatite molecules fabricated by foaming in supercritical carbon dioxide and by selective laser sintering were used for culturing of mesenchymal stromal cells from the human adipose tissue. Experiments showed that stromal cells from the human adipose tissue adhered and proliferated on all(More)
5-(2-Chloroethyl)-4-methylthiazole is used in the synthesis of heminevrin ( I ) a drug used as a hypnotic, tranquilizer, and anticonvulsant [1]. In most cases, heminevrin is obtained by chlorination of 5-(2-hydroxyethyl)-4-methylthiazole (II) by thionyl chloride, with a target product yield of 40 85% [2 6]. The purpose of this work was to study the(More)
Many graphics and animation applications depend upon convergence of geometric algorithms, which is the unifying theme for the two innovations presented here. The first extends ray-tracing in graphics over a richer family of input surfaces. The second improves temporal anti-aliasing in animation through topological considerations. Results of numerical(More)
