In this study, we explored how ammonium and metal ion stresses affected the production of recombinant hyperthermostable manganese superoxide dismutase (Mn-SOD). To improve Mn-SOD production, fed-batch culture in shake flasks and bioreactor fermentation were undertaken to examine the effects of $$ {\text{NH}}_{ 4}^{{^{ + } }} $$ NH 4 + and Mn2+ feeding.(More)
In order to study the temperature distribution and the corresponding temperature effects on pre-stressed concrete (PC) curved box girder bridge in Shandong Province, this paper builds and adopts an automatic remote real-time temperature collection system to collect temperature data on site, and further uses the software ANSYS for analysis. Based on the(More)
