Analysis on Pipeline Dents Re-Rounding under Fluctuating Internal Pressure

open access: yesShiyou jixie, 2022
During the operation of oil/gas pipelines, fluctuation of the internal pressure is inevitable. Analysis on the re-rounding process of pipeline dents under fluctuating internal pressure is very important to ensure the safety evaluation results of pipeline

Acoustic power measurements of oscillating flames [PDF]

open access: yes, 1981
The acoustic power of an oscillating flame is measured. A turbulent premixed propane/air flame is situated near a pressure antinode of a standing wave in a laboratory combustion chamber. This standing wave is generated by a piston.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Joint statistics between velocity-gradient and fluctuating pressure in a turbulent planar jet

open access: yesNihon Kikai Gakkai ronbunshu, 2017
Joint statistics between velocity gradient and fluctuating static pressure in a turbulent planar jet are experimentally investigated. The experimental data was acquired by simultaneous measurements of velocity gradient ( ∂u’2/∂x1 and ∂u’1/∂x2, where u’1,

Fluctuation [PDF]

open access: yesCirculation, 2012
Effective drug treatment of hypertension for the prevention of fatal and nonfatal cardiovascular disease passed its 50th anniversary 2 years ago.1 Until recently, the most consistent observation among trials had been that stroke risk was directly related to the fall in blood pressure on treatment.2 Older trials established the value of antihypertensive

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

open access: yesFEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
