Yb2Si2O7/Si environmental barrier coatings (EBCs) were produced by air plasma spray (APS) and low-pressure (LPPS) processes. The phase composition, microstructure, bonding strength of APS LPPS EBCs investigated. Thermal cycling tests performed in steam atmosphere respectively at 1316 °C for both EBCs. There is no coating failure after 900 cycles. In contrast, have an average life 576 cycles a t...

The present study explores a little-studied and reinterpreted early Roman Imperial cameo depicting Antonia Minor (36 bc–ad 37), which came into the possession of Holy emperor, Charles IV Luxembourg (1316–78), collector ancient gems. It was presumably by his order that set in splendid gold reliquary cross he commissioned after imperial coronation to house relics True Cross. Thus, new setting, co...

We have observed NGC 1316 (Fornax A) with the ROSAT HRI. In this paper, we present the results of these observations and we complement them with the spectral analysis of the archival PSPC data. The spectral properties suggest the presence of a significant component of thermal X-ray emission (> 60%), amounting to ∼ 10 9 M ⊙ of hot ISM. Within 3 ′ from the nucleus of NGC 1316, the HRI X-ray surfa...

OBJECTIVE To determine whether thyroid-stimulating hormone (TSH) concentrations in a large sample of neonates meet World Health Organization criteria for an iodine-replete population (< 3% of neonates with whole-blood TSH concentrations > 5 mlU/L), and, in a small subset of neonates, to examine the correlation between maternal urinary iodine and neonatal TSH concentrations. DESIGN Cross-secti...

Introduction: The Yaxcopoil borehole (Yax-1) penetrates below the suevitic units through 600 m of sediments (894.9 m – 1510.9 m). These rocks are most likely of Cretaceous age and are regarded as a displaced “megablock”. The stratified sequence was intruded by suevitic dikes (910 m, 916 m), one impact melt dike (1347 m) and several clastic, polymict dikes. The latter are the focus of this study...
