Cavefish dorsoventral axis angle during wall swimming: laterality asymmetry [PDF]

open access: yesSubterranean Biology
The Astyanax fish exhibits two morphs: an eyed, pigmented surface morph and an eyeless, depigmented cave morph. Previous studies have shown that blind morphs swim nearly parallel to the wall and can sense detailed information about objects by gliding ...

Optimizing the geometry of hunchbacked block-type gravity quay walls using non-linear dynamic analyses and supervised machine learning technique [PDF]

open access: yesمهندسی عمران شریف
In the present study, the seismic behavior of hunchbacked block-type gravity quay walls rested on non-liquefiable dense seabed soil layer is investigated, and the optimal geometries for these wall types are proposed by performing non-linear time history ...

Aerodynamic sound generated by the collision of a vortex pair with a corner

open access: yesNihon Kikai Gakkai ronbunshu, 2021
This study investigates the mechanisms of the aerodynamic sound emitted by the collision of a vortex pair with a corner. When the vortex pair collides with the corner of a wall at a 45° angle of incidence, a reflection-symmetric vortex motion is observed,

Probing the molecular architecture of Arabidopsis thaliana secondary cell walls using two- and three-dimensional 13C solid state nuclear magnetic resonance spectroscopy [PDF]

open access: yes, 2015
The plant secondary cell wall is a thickened polysaccharide and phenolic structure, providing mechanical strength to cells, particularly in woody tissues. It is the main feedstock for the developing bioenergy and green chemistry industries.

Experimental analysis of fluid‐assisted injection molding of pipe fittings with different angles by short‐shot method

open access: yesEngineering Reports, 2023
Based on the self‐assisted injection experimental platform, experimental studies on gas‐assisted injection molding (GAIM), and water‐assisted injection molding (WAIM) of 2 curved pipe fittings by adopting short‐shot method were carried out. UDF model was

Optical Absorption and Raman Spectroscopy Study of the Fluorinated Double-Wall Carbon Nanotubes [PDF]

open access: yes, 2006
Double-wall carbon nanotube (DWNT) samples have been fluorinated at room temperature with varied concentration of a fluorinating agent BrF3. Content of the products estimated from X-ray photoelectron data was equal to CF0.20 and CF0.29 in the case of ...

Wall thickness uniformity of railway hollow shafts by cross-wedge rolling

open access: yes工程科学学报, 2015
Wall thickness uniformity is an important quality criterion of railway hollow shafts by multi-wedge synchrostep cross wedge rolling. The stable rolling condition of railway hollow shafts in this rolling process is analyzed,and a flattening instability ...

Calibration of effective interface friction angle in granular flow impact experiment

open access: yesFrontiers in Earth Science, 2022
By using the normal and tangential forces measured in experiments of granular flow impact against a retaining wall, the effective interface friction angle of the wall was calculated in the dynamic phase and the static phase respectively, designated as ...
