The study of hydrodynamic characteristic of bivalves
PROCEEDINGS OF CIVIL ENGINEERING IN THE OCEAN, 1997 For bivalves under sand (surf clam (Pseudocardium sybillae), sunray surf clam (Mactra chinensis carneopicta pilsbry) and great northern tellin (Peronidia venulosa)) and the bivalve on sand (scallop (Patinopecten yessoensins)), form factors (e. g., projective area and volume), drag coefficient, lift coefficient and added mass coefficient were measured ...

Influence of Flanks on Resistance Performance of High-Speed Amphibious Vehicle
Journal of Marine Science and Engineering, 2021 In order to reduce the additional resistance of high-speed amphibious vehicles, Flanks are designed on the concave grooves. As a new drag reduction attachment, the principle of Flanks is analyzed and discussed in detail. In this paper, the HSAV model and

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Protocol for quantifying miRNA trafficking across the endosomal membrane
FEBS Open Bio, EarlyView.An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

FEBS Open Bio, EarlyView.In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...
