EFFECT OF MAGNETIC TREATMENT OF CUTTINGS AND IRRIGATION WATER ON VEGETATIVE PROPAGATION OF [PDF]

open access: yesMesopotamia Journal of Agriculture, 2006
Semi-hard wood cuttings of Carissa grandiflora planted at 15 April 2005 on river sand media, half of them were proposed to magnetic field 0.3 × 10-3 Tesla at the base of cutting for 30 second and other cuttings did not, each group divided into two halves,

The Coronal Structure of AB Doradus

open access: yes, 2010
We perform a numerical simulation of the corona of the young, rapidly rotating K0 dwarf AB Doradus using a global MHD model. The model is driven by a surface map of the radial magnetic field constructed using Zeeman-Doppler Imaging.

Complete Dissolution of Ball-Milled Masson Pine Using an Aqueous Sodium Hydroxide Solvent

open access: yesBioResources, 2016
An inorganic sodium hydroxide aqueous solution was developed for the dissolution of ball-milled softwood. Extractive-free Masson pine powder was prepared from the wood meal by planetary ball milling for various lengths of time.

Acetylation of Raw Cotton for Oil Spill Cleanup Application: an FTIR and 13-C MAS NMR Spectroscopic Investigation [PDF]

open access: yes, 2004
Fourier transform infrared (FTIR) and 13C MAS NMR spectroscopy have been used to investigate the acetylation of raw cotton samples with acetic anhydride without solvents in the presence of different amounts of 4-dimethylaminopyridine (DMAP) catalyst ...

The use of various magnetic adsorbents for cadmium uptake from dyes-containing wastewater

open access: yesEmerging Contaminants, 2023
Simultaneous presence of organic dyes with Cd(II) is possible and may affect Cd(II) removal from wastewater. This study involved various magnetic adsorbents for Cd(II) removal in the presence of various organic dyes (Tartrazine, Allura red, Rhodamine ...

Polar confinement of the Sun's interior magnetic field by laminar magnetostrophic flow

open access: yes, 2011
The global-scale interior magnetic field needed to account for the Sun's observed differential rotation can be effective only if confined below the convection zone in all latitudes, including the polar caps.

PM2.5 Magnetic Properties in Relation to Urban Combustion Sources in Southern West Africa

open access: yesAtmosphere, 2021
The physico-chemical characteristics of particulate matter (PM) in African cities remain poorly known due to scarcity of observation networks. Magnetic parameters of PM are robust proxies for the emissions of Fe-bearing particles.

Using an Ellipsoid Model to Track and Predict the Evolution and Propagation of Coronal Mass Ejections

open access: yes, 2012
We present a method for tracking and predicting the propagation and evolution of coronal mass ejections (CMEs) using the imagers on the STEREO and SOHO satellites.

Stellar magnetism, winds and their effects on planetary environments

open access: yes, 2016
Here, I review some recent works on magnetism of cool, main-sequence stars, their winds and potential impact on surrounding exoplanets. The winds of these stars are very tenuous and persist during their lifetime.
