Kinetic helicity and MHD turbulence

, 2000
The issue of dynamical anisotropy in helical three-dimensional magnetohydrodynamic turbulence with a mean magnetic field B₀ is investigated. Using high-resolution direct numerical simulations, we follow the evolution of various isotropic initial states ...

Maintaining egg freshness in the absence of refrigeration: The potential of zero‐energy cooling pots

JSFA reports, EarlyView.
Abstract Background Egg storage in regions with unreliable electricity is challenging, leading to rapid quality deterioration and postharvest losses. This study evaluated the efficacy of a Zero‐Energy Cooling (ZEC) pot, an evaporative cooling technology, for preserving table egg quality in comparison to conventional refrigeration and ambient storage ...

Effect of encapsulated purple sweet potato (Ipomoea batatas L.) peel extract on fresh goat cheese: quality and polyphenolic and color stability during refrigerated storage

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The aim of this work was to characterize the polyphenolic profile of encapsulated purple sweet potato peel extract (PSPPE), to assess the effects of its addition (1.5 and 3 g L−1) on the color, texture, microbiological quality, microstructure, and sensory attributes of fresh goat cheese, and to monitor the polyphenolic profile and ...

Linear Toroidal‐Inertial Waves on A Differentially Rotating Sphere with Application to Helioseismology: Modeling, Forward and Inverse Problems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on the sphere, the stream function of the flow satisfies a fourth‐order scalar equation.

Large-eddy simulation of very large kinetic and magnetic Reynolds number isotropic magnetohydrodynamic turbulence using a spectral subgrid model [PDF]

, 2006
A spectral subggrid-scale eddy viscosity and magnetic resisitivity model based on the eddy-damped quasi-normal Markovian (EDQNM) spectral kinetic and magnetic energy transfer presented in [12] is used in large-eddy simulation (LES) of large kinetic and ...

Mesoscale Eddy Kinetic Energy budgets and transfers between vertical modes in the Agulhas Current

, 2022
Western boundary currents are hotspots of mesoscale variability and eddy-topography interactions, which channel energy toward smaller scales and eventually down to dissipation. Here, we assess the main mesoscale eddies energy sinks in the Agulhas Current

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Modulation of eddy kinetic energy, temperature variance, and eddy heat fluxes by surface buoyancy forcing

, 2013
Although mesoscale eddies are a ubiquitous feature of the world's oceans, mechanisms determining their strength and variability remain poorly understood.

Vertical distribution of intraseasonal variation signals in the Kuroshio Current source area during 2018–2020

Frontiers in Marine Science
In the Kuroshio Current (KC) source area, intraseasonal variation (ISV) plays a significant role in dynamic oceanic processes. This study used data collected from three moorings (122.7°E, 123°E, 123.3°E) along 18°N from January 2018 to May 2020 to ...

A Stopped‐Flow Instrument for Millisecond Timescale Reaction Monitoring on a Standard NMR Spectrometer

Magnetic Resonance in Chemistry, EarlyView.
A new stopped‐flow instrument allows kinetic measurements of reactions 10 milliseconds after initiating them by mixing in a flow cell inserted into a standard NMR probe and spectrometer. High‐speed video, pressure and NMR line‐shape data are used to characterise mixing and stopping, and a protodeboronation reaction with a 5‐millisecond half‐life used ...
