Structure and relaxor behavior of BaBi4Ti4−Zr O15 ceramics

Current Applied Physics, 2010
Abstract BaBi 4 Ti 4− x Zr x O 15 with x  = 0.1, 0.2, 0.3 and 0.5, has been synthesized via modified solid state reaction route. X-ray diffraction studies confirmed the formation of single phase Zr 4+ substituted BaBi 4 Ti 4 O 15 up to x  = 0.2.

O15 Traitements pharmacologiques des douleurs neuropathiques : état des lieux

Douleurs : Evaluation - Diagnostic - Traitement, 2007
Le traitement de la douleur neuropathique (DN) reste difficile malgre la mise a disposition de nouvelles molecules ces dix dernieres annees. L’evaluation de l’efficacite des traitements est realisee de facon globale (modification de l’EVA) dans des populations dont l’etiologie lesionnelle (diabete, zona) est classique, et plus recemment en fonction des

Escherichia coli Serotype O15:K52:H1 as a Uropathogenic Clone

Journal of Clinical Microbiology, 2000
ABSTRACT To clarify the clinical and bacteriological correlates of urinary-tract infection (UTI) due to Escherichia coli O15:K52:H1, during a 1-year surveillance period we prospectively screened all 1,871 significant E. coli urine isolates at the Hospital de la Santa Creu i Sant Pau,

Thermal properties of K3Li2−x Nb5+x O15±δ crystals

Physics of the Solid State, 2003
The unit-cell parameters of the nonlinear crystal K3Li2−xNb5+xO15±δ were measured with x-ray diffraction in the temperature region 80–300 K. The room-temperature parameters of the crystal of this composition are a=12.599±0.001 and c=4.018±0.001 A.

Right frontotemporal activation by tonal memory in dyslexia, an O15 PET study

Biological Psychiatry, 1994
A prior study documented the failure of dyslexic men to activate left temporoparietal cortex during phonologic processing. Because of reports of an anomalous right planum temporale in developmental dyslexia, the functional implications of which are unknown, this study examined the ability of dyslexics to activate right temporal cortex.

O15-3 Reality and aetiology: target parameters in occupational epidemiology

Oral Session 15 – Statistical Methods, 2016
The determination of appropriate standards for workplace exposure requires accurate estimation of the health effects. This will sometimes require adjustment for the Healthy Worker Survivor Effect (HWSE) using g-methods, which can adjust for the time-varying confounding on the causal pathway that characterises this bias.
