The structure of the title compound, C(19)H(28)O(2), has been redermined at 295 (2) K, with much improved precision. The structure and mol-ecular packing of the title compound was first reported by Coiro et al. [Acta Cryst. (1973). B29, 1404-1409] by means of potential-energy calculations. The cell parameters in this study differ considerably in space group C2. It is a derivative of testosteron...

A version of the fast multipole method (FMM) is described for charge distributions on the line. Previously published schemes of this type relied either on analytical representations of the potentials to be evaluated (multipoles, Legendre expansions, Taylor series, etc.) or on tailored representations that were constructed numerically (using, e.g., the singular value decomposition (SVD), artific...

2014 A detailed Mössbauer study of the spin glass alloy Rh 5 % Fe has been performed with emphasis on the temperature zone 12.5 K-16 K (above Tg =12.5 K), where a hyperfine structure begins to appear. For such a study Rh Fe is more convenient than Au Fe, due to the absence of pair quadrupole effects. It is found that a tentative interpretation of the Mössbauer linewidth in terms of dynamic crit...

Accidents in children with epilepsy are an actual concern of teachers and parents in Greece and internationally. The aim of this study was to investigate the relationship between the knowledge and attitudes of teachers and the frequency of accidents caused by epilepsy in Greece. The study surveyed 1404 public elementary school teachers from all prefectures of the country by an anonymous questio...

The sarcomeric proteins and organization of cardiac myofibrils appeared intact in multiple unrelated patients with hypertrophic cardiomyopathy. In two subjects demonstrating the missense mutation at position 403 (Arg to Gln) in the 13-myosin heavy chain gene, total myosin and immunoreactive 3-myosin heavy chain levels were similar to those found in other patients with hypertrophic cardiomyopath...
