Investigation of urinary magnesium excretion as an indicator of magnesium status in dairy cows
Magnesium (Mg) status was monitored in a herd of dairy cows in early lactation during spring (August - December). This herd is on seasonal supply with a compact spring calving of the whole herd between August to October. The cows were grazed on pasture (predominantly ryegrass and white clover). One …

Combustion of fine magnesium particles
… addressed in many recent studies, combustion of magnesium explored mostly coarse, 50 um, and larger particles. This effort is focused to characterize and understand combustion dynamics for fine Mg powders. Spherical, micron-sized magnesium particles were introduced in an air-acetylene flame using …

Hot workability of magnesium alloys
For the alloy AZ91 (Mg-9.OAl-0.7Zn-0.13Mn) die cast specimens were subjected to torsion testing at 150, 180, 240, 300, 420 and 450C̕ at 0.05 0.5 and 5.0 s -1 The as-cast specimens exhibited hot shortness at 360C̕ and above; however in that domain, after prior thermomechanical processing (TMP) at …

Solidification behaviour of magnesium alloys
Magnesium alloys have been extensively used for structural and functional applications due to their low densities. In order to improve the mechanical properties, grain refinement of the microstructures of magnesium alloys has been studied for many years. However, an effective and efficient grain …

The effect of magnesium ions on the current efficiency of magnesium anodes used as cathodic protectors
… to determine, if possible, whether or not the magnesium ion concentration in the backfill has a significant effect upon the current efficiency of a pure magnesium anode when used to protect a steel cathode. Accordinging to H.A. Robinson, there should normally be no effect, but he indicated that …

Magnesium Diboride Superconducting Devices and Circuits
While magnesium diboride (MgB2) was first synthesized in the 1950s, MgB2’s superconductive properties were not discovered until 2001. It has the highest superconducting transition temperature of all the metallic superconductors at ~39 K at atmospheric pressure. MgB2 is also unique in that it has a …

Magnesium homeostasis in the mammalian heart
The magnesium ion (Mg2 ) is involved in a variety of physiological and biochemical processes including the activation of over 300 enzymes and the control of transmembrane movement of cations. In most mammalian cells intracellular Mg2+ is kept well below electrochemical equilibrium. In cardiac …

The Osseointegration of Magnesium Oxidized Implant
… study is to compare the osseointegration between magnesium oxidized implant, TiUnite and machine-turned implant, to establish a better understanding of the effect of anodic oxidization on commercially pure titanium. METHODS: 3 Mini pigs (24 months) were chosen and from 1st premolar to 2nd molar of …

Core excitons in amorphous magnesium alloys
High resolution photoabsorption spectra were obtained in the range 40200 eV for Mg-Group V alloys. Sharp line structure was discovered for amorphous alloys of Mg-Bi and Mg-Sb near the photoabsorption threshold of the Mg 2p core level. These lines were strongest for compositions corresponding to the …

Magnesium nanoplasmonics: synthesis, characterisation, and applications
At the nanoscale, light-matter interactions differ markedly from bulk behavior. In metal nanoparticles, resonant oscillations of conduction-band electrons driven by light lead to localised surface plasmon resonances (LSPRs). Au and Ag are widely studied metals capable of sustaining LSPRs, but there …
