All Swirl Is Not The Same

Journal of College Orientation, Transition, and Retention
Swirl, or the back-and-forth transfer across multiple colleges, has been the focus of policy-makers, practitioners, and researchers alike because of its empirical connections with retention and degree completion.

Study of Silicide Formation in Large Diameter Monocrystalline Silicon

East European Journal of Physics
To study the formation of silicides, dislocation-free ingots of single-crystalline silicon with a diameter of 65÷110 mm, grown by the Czochralski method, were used.

On the impingement of heat transfer using swirled air jets

Frontiers in Mechanical Engineering, 2023
Experimental analyses were conducted under identical experimental conditions on the heat transfer between a constant heat flux flat plate and a round air jet for both conventional and swirled jets.

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

Molecular 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.

Mass transport using the series of vortex rings with swirl

Journal of Fluid Science and Technology, 2014
Behavior of the series of laminar vortex rings with circumferential flow, so-called swirl, were investigated using flow visualization, to evaluate the transport efficiency of the ejected fluid as vortex rings.

Design and testing of a contra-rotating tidal current turbine [PDF]

, 2005
A contra-rotating marine current turbine has a number of attractive features: nearzero reactive torque on the support structure, near-zero swirl in the wake, and high relative inter-rotor rotational speeds.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Flame–Flame Interactions and Jet–Jet Interactions in Gas Turbine Swirl Combustors

Energies
Annular combustors are widely used in newly developed aero-engines. Nevertheless, the development of annular combustors requires substantial air supplies and high-power heaters during testing, leading to high experimental costs.

The limit of vanishing viscosity for the incompressible 3D Navier-Stokes equations with helical symmetry

, 2017
In this paper, we are concerned with the vanishing viscosity problem for the three-dimensional Navier-Stokes equations with helical symmetry, in the whole space.
