DEVELOPMENT OF STEEL PIPE PILE WITH HELICAL WINGS
AIJ Journal of Technology and Design, 2000 application/pdfThis paper describes a bearing capacity formula for steel pipe pile with four helical wings. The pile can be possessed high bearing capacity because of being screwed in with lateral soil displacement.

Composite helical micro pile’s bearing capacity
IOP Conference Series: Materials Science and Engineering, 2020 Abstract It is proposed to use two options of piles’ bearing capacity calculation based on existing Russian codes. Calculation of pipe’s section for an axial load is proposed either. Results of these calculations are compared to the site tests made earlier.

Shaking Table Test on Mitigation of Liquefaction-Induced Tunnel Uplift by Helical Pile
, 2022 The tunnels located in the shallow depths of loose saturated sand are significantly prone to liquefaction-induced uplift. Research works are, therefore, in progress to propose efficient techniques for mitigating uplift.

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.

Seismic Performance of Grouped Helical Piles in Pinned and Fixed Connections [PDF]
, 2018 Helical piles have yet to be nationally considered an acceptable foundation for structures in areas of high seismic activity. This remains despite evidence of helical pile survival stories from recent earthquakes where other foundations failed, and ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
