In order to compare pre-Columbian cultural affiliations in the Lesser Antilles, we studied three ceramic series from Guadeloupe (F.W.I.) well-dated Troumassoid sites between AD 1000 and 1300 (radiometric ages) attributed Late Ceramic Age (AD 1000–1500). The significance of different types inclusions these ceramics is discussed through a petrographic study using optical electron microscopy, that...

The occurrence of grain boundary precipitates was investigated with respect to the crystallographic orientation adjacent grains in extruded AA6110, AA6063 and AA6061 alloys brought T6 temper. It found that requirement for precipitate formation is have <100>Al directions or {100}Al planes parallel plane. highest density present when this fulfilled by both grains.

Purpose: The purpose of this study was to design a biorhythm management model for Iranian public school principals with a fuzzy Delphi approach. Methodology: The design of the present study was qualitative with fuzzy Delphi method. Statistical population, professors of organizational behavior management in universities of Mazandaran province and senior managers of education departments in citi...

We present our initial experience on first-pass gadolinium-enhanced coronary artery magnetic resonance angiography (MRA). Three-dimensional segmented gradient-echo sequences were developed to image coronary arteries within a single breathhold during the injection of a double-dose contrast agent. Comparisons were made between a short TR of 2.7-msec (n = 5) and a long TR of 5.0-msec (n = 3) seque...

Background Cine DENSE MRI is an established myocardial strain imaging technique with high accuracy and rapid data analysis. Current cine DENSE protocols utilize breathholding (BH); however, this practice limits the use of this technique to patients with good BH capabilities, excluding many pediatric and some heart failure patients. We propose a free-breathing (FB) framework for cine DENSE that ...

BACKGROUND Computer simulations are important for validating novel image acquisition and reconstruction strategies. In cardiovascular magnetic resonance (CMR), numerical simulations need to combine anatomical information and the effects of cardiac and/or respiratory motion. To this end, a framework for realistic CMR simulations is proposed and its use for image reconstruction from undersampled ...
