Frontiers of Structural and Civil Engineering 2018, Volume 12, Issue 1,   Pages 148-162 doi: 10.1007/s11709-016-0375-5

Abstract: Finite element modeling of the HSS braces that utilizes the true stress-strain curves produces hysteresisTrue stress-strain curves are obtained from coupon tests or stub-column tests while utilizing an exponentialfunction or strain hardening rule with a trial and error procedure to obtain the hysteresis behaviorIn the current study, the true stress-strain curves are directly obtained from tests on stub-columnsResults indicate that the stress-strain curves for these braces are not unique.

Strain and process engineering toward continuous industrial fermentation

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 10,   Pages 1336-1353 doi: 10.1007/s11705-022-2284-6

Abstract: Most current biotechnology industries are based on batch or fed-batch fermentation processes, which often show low productivity and high production costs compared to chemical processes. To increase the economic competitiveness of biological processes, continuous fermentation technologies are being developed that offer significant advantages in comparison with batch/fed-batch fermentation processes, including: (1) removal of potential substrates and product inhibition, (2) prolonging the microbial exponential growth phase and enhancing productivity, and (3) avoiding repeated fermentation preparation and lowering operation and installation costs. However, several key challenges should be addressed for the industrial application of continuous fermentation processes, including (1) contamination of the fermentation system, (2) degeneration of strains, and (3) relatively low product titer. In this study, we reviewed and discussed metabolic engineering and synthetic biology strategies to address these issues.
