Quaternary dating by electron spin resonance
(ESR) applied to human tooth enamel.
Presentamos excusas a nuestros lectores y al antropOlogo Javier AndrEs Sandoval Andrade puesto que en el Vol 15 No 2 del 2011 de la revista Earth Science research Journal (ESRJ) se publico el articulo titulado "Quaternary dating by electron spin resonance
(ESR) applied to human tooth enamel" en el cual no se hace un correcto pie de pagina de la figura 1, ya que no es tomada de (Groot, 1992) como reza la misma, sino que es tomada de la tesis de pregrado titulada DATACION DE RESTOS HUMANOS PREHISPANICOS A TRAVES DE ESMALTE DENTAL USANDO RESONANCIA PARAMAGNETICA ELECTRONICA (EPR) (2010).
The main interest of electron spin resonance
lies in the study of free radicals having unpaired electrons.
4] Nonstandard abbreviations: ESR, electron spin resonance
spectroscopy; DR, discriminant variable.
We will polarize lanthanum nuclear spins by using a dynamic nuclear polarization upon a paramagnetic electron spin resonance
(ESR) in a single crystal of a lanthanum compound.
The particles were removed by centrifugation, and the solution was analyzed in a capillary column by electron spin resonance
(ESR) spectroscopy (Bruker ESP300 ESR spectrometer; Bruker, Ettlinger, Germany).
Electron paramagnetic resonance (EPR) spectroscopy, which is also known as electron spin resonance
, exploits the spin of unpaired electrons in paramagnetic materials.
Scientists will use electron spin resonance
spectroscopy to study the effect of processing conditions and improvers on soluble protein mobility in situ in doughs.
INFLUENCE OF MINERALOGY AND GRAIN SIZE ON THE ELECTRON SPIN RESONANCE
SIGNAL OF LOESS.
MAFF scientists have published the protocols for four fully-validated tests: detection of irradiated herbs and spices using thermoluminescense technology; detection of irradiated bone-containing meat using electron spin resonance
spectroscopy; detection of irradiated food containing fat by using 2-alkylcyclobutanone markers; and detection of irradiated poultry meat using the Limulus Amoebocyte Lysate test in conjunction with a gram-negative bacterial count.
The current research used three dating methods--uranium series, electron spin resonance
and optically stimulated luminescence--to establish that the burial of this man took place between 56,000 and 68,000 years ago.
To make the measurements, the team used an electron spin resonance
spectrometer that gives highly precise results.
