The applicability of advanced numerical methods for the solution of the orbit determination problem is studied. The dynamics of the observed object is written as a system of integral equations. This system is solved numerically by representing the components of the force function as linear combinations of B-splines and by applying the multigrid technique. In an outer loop the orbit determinatio...

Between 1999 and 2005, a Task Force composed of CORESTA members has studied the existing methodologies for the determination of the Tobacco Specific Nitrosamines (TSNAs) in the mainstream smoke of cigarettes. Several methods have been proposed for this determination, which are mainly based on two types of analytical methodologies: GC-TEA (Gas Chromatography with a Thermal Energy Analyser as det...

Crystal structure determination has long provided insight into structure and bonding of small molecules. When those same small molecules are designed to come together in multimolecular assemblies, such as in coordination cages, supramolecular architectures and organic-based frameworks, their crystallographic characteristics closely resemble biological macromolecules. This resemblance suggests t...

the neuropharmacological effect of petroleum ether and ethyl acetate soluble fractions of ethanol extract of the rhizome of drynaria quercifolia j. smith were studied in mice by intraperitoneal administration. the tests used were determination of effect on duration of diazepam-induced sleep, determination of effect on nikethamide-induced toxicity, light-dark test and force swimming test. the du...

A detailed investigation into the analysis of beams with different boundary conditions. carrying either a moving mass or force is performed. Analytical and numerical techniques for determination of the dynamic behavior of beams due to a concentrated travelling force or mass are presented. The transformation of the familiar Euler-Bernoulli thin beam equation into a series of ordinary differentia...
