We study to what extent dielectric nanoparticles prefer to self-assemble into linear chains or into more compact structures. To calculate the Van der Waals (VdW) attraction between the clusters we use the Coupled Dipole Method (CDM), which treats each atom in the nanoparticle as an inducible oscillating point dipole. The VdW attraction then results from the full many-body interactions between t...

The aim of this study was to assess whether age-related differences in reaction time can be explained satisfactorily in terms of a global age-related differences in processing speed alone. We investigated the age-related differences in simple, discrimination and choice reaction time in 4to 6-year-old children and young adults using approach proposed by Madden et al. and Ridderinkhoff & van der ...

Ellis-van Creveld syndrome (EVC) is a rare chondroectodermal dysplasia presenting several skeletal manifestations and congenital heart malformations. Polydactyly is the most frequent skeletal anomaly. The authors report two cases of EVC syndrome with different manifestations, which underwent surgical treatment for polydactyly.

An inbred kindred with 15 cases of the autosomal recessive Ellis-van Creveld syndrome is reported. The ages of the 12 living affected varied between 3 and 82 years. The main characteristics include polydactyly of the hands and feet and several other skeletal anomalies, oral manifestations, and malformations of the heart in 50% of the living affected.

ellis-van creveld syndrome is a very rare autosomal recessive skeletal dysplasia characterized by a short stature, short limbs, short ribs, postaxial polydactyly, dysplastic nails, multiple frenula, and congenital heart defects.  we describe a 22-year-old boy with a short stature, short limbs, short distal extremities, small teeth, short upper lip bound by frenula to the alveolar ridge, multipl...

Since the 1970s, women have been increasingly integrated into the military; in Iraq and Afghanistan many women served on the frontline in combat. This article argues women’s integration has been facilitated by the all-volunteer professional forces in which individuals are judged purely by competence. Female soldiers have been accepted in all military roles if they perform competently. There are...
