The Line-broken Analysis of the Aluminum Conductor Composite Core
Aluminum conductor composite core has many technical advantages such as high tensile strength, light weight, low sag, large current carrying capacity. In order to study the influence of the broken of aluminum conductor composite core on the transmission tower, tower-line model was built by using the finite element software ANSYS/LS-DYNA, and the deformation of joints and stress of bar were analyzed. The impact load and the impact coefficient of the representative bars of the transmission tower are calculated. The results show that the impact acting on the tower is the most serious in the place of the conductor suspension point, the connection of upper and lower crank arms, the tower neck
Optimizing the Biosynthesis of Dihydroquercetin from Naringenin in Saccharomyces cerevisiae
Dihydroquercetin
(DHQ), known for its varied physiological benefits,
is widely used in the food, chemical, and pharmaceutical industries.
However, the efficiency of the DHQ synthesis is significantly limited
by the substantial accumulation of intermediates during DHQ biosynthesis.
In this study, DHQ production was achieved by integrating genes from
various organisms into the yeast chromosome for the expression of
flavanone-3-hydroxylase (F3H), flavonoid-3′-hydroxylase, and
cytochrome P450 reductase. A computer-aided protein design approach
led to the development of optimal F3H mutant P221A, resulting in a
1.67-fold increase in DHQ yield from naringenin (NAR) compared with
the control. Subsequently, by analysis of the enzyme reaction and
optimization of the culture medium composition, 637.29 ± 20.35
mg/L DHQ was synthesized from 800 mg/L NAR. This corresponds to a
remarkable conversion rate of 71.26%, one of the highest reported
values for DHQ synthesis from NAR to date
