Strain-rate tensor vorticity tensor. The vorticity represents rotation of a uid particle. Inserting Eq. 1.7 into Eq. 1.8 gives i = ijk (Skj + kj ) = ijk kj (1.10) 1.3. Strain rate tensor, vorticity. 12. since ijk Skj = 0 because the product of a symmetric tensor (Skj ) and a anti-symmetric tensor (ijk ) is zero.

Integrated strain- and process design enable production of 2019-11-6 · Itaconic acid is an unsaturated, dicarboxylic acid which finds a wide range of applications in the polymer industry and as a building block for fuels, solvents and pharmaceuticals. Currently, Aspergillus terreus is used for industrial production, with titers above 100 g L−1 depending on the conditions. Besides A. terreus, Ustilago maydis is also a promising itaconic acid production host due DUCTILE SHEAR ZONES 2017-1-6 · The curvature of the sigmoidal foliation trace, comparable in shape (and shape only) to drag folds, is a direct indicator of the sense of shear. viscous flow taking place under constant stress, externally applied strain rate, and stress state. Spacing Shear zones may appear as regularly spaced, high strain planar structures. Investigation of poly(γ-glutamic acid) production via Poly(γ-glutamic acid) (γ-PGA) is a biopolymer with many useful properties making it applicable for instance in food and skin care industries, in wastewater treatment, in biodegradable plastics or in the pharmaceutical industry. γ-PGA is usually produced microbially by different Bacillus spp. The produced γ-PGA increases the viscosity of the fermentation broth. 8.1 Introduction to Plasticity - Auckland
