Solar magnetic fields [PDF]

open access: yesPhysics of the Earth and Planetary Interiors, 2011
This review provides an introduction to the generation and evolution of the Sun's magnetic field, summarising both observational evidence and theoretical models. The eleven year solar cycle, which is well known from a variety of observed quantities, strongly supports the idea of a large-scale solar dynamo.

Overcoming Antimicrobial Resistance in Bacteria Using Bioactive Magnetic Nanoparticles and Pulsed Electromagnetic Fields

open access: yesFrontiers in Microbiology, 2018
Nisin is a known bacteriocin, which exhibits a wide spectrum of antimicrobial activity, while commonly being inefficient against Gram-negative bacteria.

Magnetic Fields at Neptune [PDF]

open access: yesScience, 1989
The National Aeronautics and Space Administration Goddard Space Flight Center-University of Delaware Bartol Research Institute magnetic field experiment on the Voyager 2 spacecraft discovered a strong and complex intrinsic magnetic field of Neptune and an associated magnetosphere and magnetic tail.

Measurement of Transient Permeability of Sp2/0 Myeloma Cells: Flow Cytometric Study

open access: yesMeasurement Science Review, 2016
Electroporation is an electric field induced phenomenon occurring when the permeability of the cell membrane is increased due to the excess of critical transmembrane potential.

Topological structure of the magnetic solar corona [PDF]

open access: yes, 2007
The solar corona is a highly complex and active plasma environment, containing many exotic phenomena such as solar flares, coronal mass ejections, prominences, coronal loops, and bright points.

Open Magnetic Fields in the Martian Magnetosphere Revealing Dipole-like Intrinsic Magnetic Fields at Mars

open access: yesThe Astrophysical Journal Letters, 2023
Mars’s magnetosphere is hybrid, having contributions from both an induced magnetosphere like Venus and the localized crustal magnetic fields. However, the planetary fields also include large-scale, more global components.

α Effect and Magnetic Diffusivity β in Helical Plasma Under Turbulence Growth

open access: yesUniverse
We investigate the transport coefficients α and β in plasma systems with varying Reynolds numbers while maintaining a unit magnetic Prandtl number (PrM). The α and β tensors parameterize the turbulent electromotive force (EMF) in terms of the large-scale

Induction of Different Sensitization Patterns of MRSA to Antibiotics Using Electroporation

open access: yesMolecules, 2018
Treatment of bacteria-associated infections is complicated and antibiotic treatment alone is often inadequate to overcome biofilm infections. Physical methods allow overcoming this problem and propose solutions that are non-dependent on drug resistance ...

Magnetic field tomography [PDF]

open access: yesThe European Physical Journal D, 2001
Neutral atoms may be trapped via the interaction of their magnetic dipole moment with magnetic field gradients. One of the possible schemes is the cloverleaf trap. It is often desirable to have at hand a fast and precise technique for measuring the magnetic field distribution.

The effect of magnetic fields in chemistry and biology [PDF]

open access: yes, 1997
This thesis is concerned with the effect of static and oscillatory magnetic fields on the yield of radical recombination reactions and the proposal that such effects may constitute a possible mechanism for the interaction of
