Abstract An overdenture is a denture supported partly by soft tissues and retained teeth or implants. Magnetic tooth-retained overdentures are used to increase support, retention, stability but also prevent alveolar ridge resorption. attachments the retention of partial complete dentures regardless path insertion and, in addition, can be for abutment with periodontal disease. This paper discuss...

Whether conventional gradient-echo (GE) blood oxygenation-level-dependent (BOLD) functional magnetic resonance imaging (fMRI) is able to map submillimeter-scale functional columns remains debatable mainly because of the spatially nonspecific large vessel contribution, poor sensitivity and reproducibility, and lack of independent evaluation. Furthermore, if the results from optical imaging of in...

Imaging polarimetry of the 850 km continuum emission in the NGC 7538 region, obtained with the SCUBA Polarimeter, is presented. The polarization map is interpreted in terms of thermal radiation by magnetically aligned dust grains. Two prominent cores associated with IRS 1 and IRS 11, IRS 1(SMM), and IRS 11(SMM), are found in the surface brightness map. Although these cores look similar in surfa...

This study was an attempt to investigate the comparative impact of concept map and mind map instruc- tion on EFL learners’ descriptive and narrative writing. To fulfill this purpose, 60 intermediate EFL learners were selected from among a total number of 100 through their performance on a pretest, i.e., a piloted sample Cambridge Preliminary English Test (PET). T...

In functional MRI, head motion may cause dynamic nonlinear field-inhomogeneity changes, especially with large out-of-plane rotations. This may lead to dynamic geometric distortion or blurring in the time series, which may reduce activation detection accuracy. The use of image registration to estimate dynamic field inhomogeneity maps from a static field map is not sufficient in the presence of s...
