Core-loss EELS

Current Opinion in Solid State and Materials Science, 1998
Abstract It is now possible to create an atom sized electron beam that can probe the electronic structure of materials on the scale. Electrons passed through an electron spectrometer from such a probe give energy loss spectra that can provide insight on the local chemistry, bonding and electronic structure.

The Fate (Outcome) of Clinically Apparent Single Lesion and Oligofocal Nephroblastomatosis Treated According to SIOP/GPOH Protocols for Wilms Tumor

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between

The impact of the mixing properties within the Antarctic stratospheric vortex on ozone loss in spring [PDF]

, 2001
Calculations of equivalent length from an artificial advected tracer provide new insight into the isentropic transport processes occurring within the Antarctic stratospheric vortex. These calculations show two distinct regions of approximately equal area:
