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.

Instrumentation and Axial Load Testing of Displacement Piles [PDF]
, 2013 Despite the fact that results of many instrumented pile load tests have been reported in the literature, it is difficult to find well-documented instrumentation procedures that can be used when planning a load testing programme.

UNDERSTANDING THE SEISMIC RESPONSE OF SINGLE HELICAL PILES IN DRY SANDS USING A LARGE-SCALE SHAKE TABLE TEST [PDF]
, 2017 Helical piles are deep foundations composed by a steel shaft and single or multiple helical plates welded at their tip or throughout their lead section, respectively, which allows them to be screwed into the ground during installation, producing minimum ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Numerical modelling of pullout of helical soil nail
Journal of Rock Mechanics and Geotechnical Engineering, 2017 An investigation into the pullout response of helical soil nail using finite element subroutine Plaxis 2D is presented. The numerical modelling of actual pullout response is achieved by axisymmetric and horizontal loading condition. The effect of varying

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 ...

Molecular Oncology, EarlyView.Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

COMPRESSIVE CAPACITY OF HELICAL PILE FOUNDATION ON PEAT WITH VARIATION OF HELICAL PLATE DIAMETER
astonjadro, 2021 <p>The use of helical foundations to support structures on peat soil is still a new method. Research is needed to develop this foundation. There are 6 types of helical foundation tested on peat soil. To study the effect of helical plate diameter, plate diameters were varied with sizes 25 cm (M), 35 cm (L), and 45 cm (G).
