Experimental Study on Seismic Performance of Prefabricated Frame Column Joints with a High Axial Compression Ratio

Shock and Vibration, 2022
A new type of an assembled monolithic concrete column encased by partial outsourcing steel was proposed, and the seismic performance was proposed. To study the seismic performance such as failure mode, hysteretic behavior, deformation, ductility of the ...

Wet process of phosphoric acid purification by solvent extraction using tri-n-butyl phosphate and cyclohexanol mixtures [PDF]

Journal of the Serbian Chemical Society, 2017
Solvent extraction is an efficient, economical and widely-used technology for the purification of wet process phosphoric acid (WPA). This present work focused on the development of a solvent extraction system, TC, representing tri-n-butyl phosphate (TBP)

Reciprocating plate column - fundamental research and application in Serbia from 1970 to 2020 [PDF]

Hemijska Industrija
In the group of multiphase contactors and reactors, an important place belongs to reciprocat-ing plate columns (RPCs), which consist of a set of perforated plates fixed on a carrier (the so-called reciprocating or vibrating agitator) moving periodically ...

Caffeine Extraction with a Karr Reciprocating Plate Column

Engineering in Life Sciences, 2003
AbstractA Karr reciprocating plate column was used in extracting caffeine from the methylation mother solution of a caffeine synthesis plant with chloroform as the extractant. Pilot tests were carried out in a 38 mm diameter column to determine holdup, flooding and mass transfer at various reciprocation velocities.

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

Deep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Axial dispersion of the liquid phase in a three-phase Karr reciprocating plate column [PDF]

Journal of the Serbian Chemical Society, 2004
The influence of the gas flow rate and vibration intensity in the presence of the solid phase (polypropylene spheres) on axial mixing of the liquid phase in a three phase (gas-liquid-solid) Karr reciprocating plate column (RPC) was investigated. Assuming

Influence of Thermal Cycling on Friction, Wear, and Damage Evolution of Fused Deposition Modeling of 3D‐Printed Glass Fiber Reinforced Polylactic Acid Composites

Polymer Composites, EarlyView.
Schematic illustration of the experimental procedure of the specimens. ABSTRACT This research work investigated the effect of the cyclic thermo‐hygrometric aging regime between −20°C and +40°C with 0–400 cycles on the reciprocating tribological properties of fused deposition modeling (FDM) printed polylactic acid (PLA) and the same material reinforced ...
