Numerical Simulation to Leakage and Spread of Crude Oil from Submarine Buried Pipelines

Shiyou jixie, 2020
Less studies have been carried out on the law of leakage and spread of crude oil in seawater. In this study, according to fluid dynamics, a VOF model and a porous-medium model were established to investigate the effects of seawater flow rate and oil ...

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

Advanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

The Effect of Adding Different Antibiotics on the Resistance against Bacterial Leakage of AH 26 Sealer [PDF]

Journal of Dental Materials and Techniques, 2017
Aim: Most endodontic sealers show antimicrobial activity before setting, but most of them also lose this ability after setting. Addition of an antibiotic may affect the properties of sealers such as sealing ability, setting time, and so on.

Effect of Flow Instabilities and Self-Sustained Oscillations on Labyrinth Seal Leakage Resistance [PDF]

Volume 3: Heat Transfer; Electric Power; Industrial and Cogeneration, 1997
Two flow instabilities involving a bifurcated flow pattern were discovered for the throughflow jet in a stepped labyrinth seal. A bifurcation stability map was developed showing which combinations of tooth clearance and step height occur in which of the three flow regimes.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Blood-brain barrier imaging as a potential biomarker for bipolar disorder progression

NeuroImage: Clinical, 2020
Bipolar disorder affects approximately 2% of the population and is typically characterized by recurrent episodes of mania and depression. While some patients achieve remission using mood-stabilizing treatments, a significant proportion of patients show ...
