Flow field and local burning velocity affected by stretch in swirl flow of turbulent premixed flames

Journal of Thermal Science and Technology, 2022
In this study, we have investigated turbulent premixed flames affected by local stretch in a swirl flow, measured by the simultaneous OH-PLIF/SPIV system. Evaluating the transient of burning velocity and stretch rate, the flow and the flame dynamics in a

First Results from the Thomson Scattering Diagnostic on the Large Plasma Device

Instruments, 2022
We present the first Thomson scattering measurements of electron density and temperature in the Large Plasma Device (LAPD), a 22 m long magnetized linear plasma device at the University of California Los Angeles (UCLA). The diagnostic spectrally resolves

Two-Dimensional Thomson Scattering in Laser-Produced Plasmas

Instruments, 2023
We present two-dimensional (2D) optical Thomson scattering measurements of electron density and temperature in laser-produced plasmas. The novel instrument directly measures ne(x,y) and Te(x,y) in two dimensions over large spatial regions (cm2) with sub ...

Can Photobiomodulation Therapy Using an 810-nm Diode Laser Increase the Secondary Stability of Orthodontic Mini-Screws? A Split-Mouth Double-Blind Randomized Clinical Trial

Applied Sciences, 2023
Background: In orthodontic treatment, mini-screws can provide maximum anchorage conditions. If the miniscrew stability is compromised, this could jeopardize the outcomes of the orthodontic treatment or biomechanics.

Evaluation of Vaporizing Diesel Spray with High-Speed Laser Absorption Scattering Technique for Measuring Vapor and Liquid Phase Concentration Distributions

Fuels, 2023
The Conventional Laser Absorption Scattering (C-LAS) technique is used to measure the mixture concentration and visualize the vapor phase. The former is determined by the attenuation of visible and ultraviolet light whereas the latter is achieved via ...

Photodynamic Therapy of Breast Cancer in Animal Models and Their Potential Use in Clinical Trials—Role of the Photosensitizers: A Review

Frontiers in Bioscience-Landmark, 2023
In this article, we reviewed the use of photodynamic therapy (PDT) for breast cancer (BC) in animal models. These in vivo models imitate the cancer disease progression, aid diagnosis, as well as create opportunities to assess treatment during the ...

Bootstrap inversion technique for atmospheric trace gas source detection and quantification using long open-path laser measurements [PDF]

Atmospheric Measurement Techniques, 2018
Advances in natural gas extraction technology have led to increased activity in the production and transport sectors in the United States and, as a consequence, an increased need for reliable monitoring of methane leaks to the atmosphere. We present a
