Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Experimental Investigation on IceBreaking Resistance and Ice Load Distribution for Comparison of Icebreaker Bows

Journal of Marine Science and Engineering
During icebreaker navigation in ice-covered waters, icebreaking resistance and dynamic ice loads acting on the bow critically determine the vessel’s icebreaking performance.

Analysis for Coupling Characteristic and Weakness of “Source-Network-Load” Under Ice Storms [PDF]

Dianli jianshe
[Objective] Under extreme ice-disaster conditions， the power-generation capacity of wind and solar energy declines significant while the probability of power-equipment failure increases significantly， thus resulting in severe supply-demand imbalances ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Statistical Analysis of Ice Load on Icebreaker Ship Based on Stochastic Ice Fields

Journal of Marine Science and Engineering
Accurately assessing ice loads is a fundamental issue in the field of structural design for ships in ice-covered regions. In this paper, we conducted research on extreme ice load estimation for icebreaking ships, combining stochastic theory with ...

Fidelity of computational modelling of offshore jacket platforms [PDF]

, 2019
The development of oil and gas exploitation offshore has a history of about half a century. Many platforms have been built since to facilitate the production of hydrocarbons oil and gas, of which fixed offshore jacket type structures are the most ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Design consideration of two candidate propellers for ice breaking vessel

Antarctic Record, 1985
The propellers for ships operating in the Antarctic and Arctic regions encounter fragments of ice and sometimes are damaged according to the severity of ice load. The design of propellers for such ships is quite different from that of conventional ships,
