Density functional theory (DFT) calculations were performed to investigate the properties of planar, tubular and conical forms of silicon nanostructures. The evaluated parameters including averaged bond lengths, binding energies, gap energies and dipole moments were then evaluated for the optimized models of study. The results indicated that the bond lengths between silicon atoms are different ...

OBJECTIVE To investigate the use of concepts of capacity and performance when assessing functioning of stroke survivors, measured with the Functional Independence Measure (FIM) and the International Classification of Functioning, Disability and Health (ICF). METHODS During an inpatient interdisciplinary rehabilitation programme for 62 subacute stroke survivors, limitations in speaking, walkin...
