The effect of sintering condition on structure, microstructure, and ferroelectric properties ([Formula: see text][Formula: text] text]- O 3 (KNL–NTS) has been investigated. Ceramic powders have synthesized by the solid-state reaction method sintered at different temperatures (1115[Formula: text]C, 1125[Formula: 1140[Formula: text]C). Then, samples were characterized thermogravimetric analysis, ...

BACKGROUND Smoking increases CD risk. The aim was to determine if smoking cessation at, prior to, or following, CD diagnosis affects medication use, disease phenotypic progression and/or surgery. METHODS Data on CD patients with disease for ≥5 yrs were collected retrospectively including the Montreal classification, smoking history, CD-related abdominal surgeries, family history, medication u...

For the quadruple gravitational lens PG 1115+080, we combine recent measurements of the time delays with new lens models to determine the Hubble constant H 0. We explore the effects of systematic uncertainties in the lens models on the estimates of H 0 , and we discuss how the uncertainties can be reduced by future observations. We find that the lens cannot be fit by an isolated lens galaxy, bu...

We study the anomalous flux ratio which is observed in some four-image lens systems, where the source lies close to a fold caustic. In this case two of the images are close to the critical curve and their flux ratio should be equal to unity, instead in several cases the observed value differs significantly. The most plausible solution is to invoke the presence of substructures, as for instance ...
