Investigation of the Axial Force Compensation and Deformation Control Effect of Servo Steel Struts in a Deep Foundation Pit Excavation in Soft Clay

open access: yesAdvances in Civil Engineering, 2019
This study presents a comparative analysis of the deformation control effect of the hydraulic servo steel struts and ordinary steel struts of a foundation pit based on the measured axial force of the steel struts, lateral wall deflection, and ground ...

Axial force sensor for screw bolt using optical fiber grating for detection of strain

open access: yesNihon Kikai Gakkai ronbunshu, 2015
In this study, an axial force sensor was developed and evaluated for a screw bolt using optical fiber grating (FBG: fiber Bragg grating). This sensor has high tolerance to electromagnetic noise.

An axially symmetric forced convection problem [PDF]

open access: yesJournal of the Australian Mathematical Society, 1975
AbstractA simple diffusion-convection heat transfer model is formulated which leads to an axially symmetric partial differential equation. The equation is shown to be closely related to a second one which is adjoint to the original equation in one variable can and be interpreted as a description of another diffusion-convection model.

Hands‐on protocol for preparing water‐soluble fractions from agri‐food samples for NMR‐based metabolomics analysis

open access: yesFEBS Open Bio, EarlyView.
This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

open access: yesFEBS Open Bio, EarlyView.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

Stress Characteristics Analysis and Anchorage Mechanism of Pre-stressed Anchors Based on Surrounding Rock Deformation

open access: yesMeikuang Anquan, 2020
The stress distribution of pre-stressed anchors is analyzed under actual surrounding rock deformation conditions. The pre-stressed anchor-surrounding rock interaction model is established, and the axial and shear stress distributions of pre-stressed ...

Supersonic axial-force characteristics of a rectangular-box cavity with various length-to-depth ratios in a flat plate [PDF]

open access: yes
A wind-tunnel investigation has been conducted at Mach numbers of 1.50, 2.16, and 2.86 to obtain axial-force data on a metric rectangular-box cavity with various length-to-depth ratios. The model was tested at angles of attack from -4 deg to -2 deg.

Experiment measurement of Alford's force in axial-flow turbomachinery [PDF]

open access: yes, 1982
Results of experimental measurements made on a small high speed, axial flow test apparatus are presented to verify the existence of Alford's force (that circumferential variation of blade-tip clearances in axial-flow turbomachinery will produce cross ...

Magnetic field evolution and equilibrium configurations in neutron star cores: the effect of ambipolar diffusion

open access: yes, 2017
As another step towards understanding the long-term evolution of the magnetic field in neutron stars, we provide the first simulations of ambipolar diffusion in a spherical star.
