The Raychaudhuri equation is derived by assuming geometric flow in space–time M of n+1 dimensions. turns into a harmonic oscillator form under suitable transformations. Thereby, relation between geometrical entropy and mean geodesic deviation established. This has connection to chaos theory where the trajectories diverge exponentially. We discuss its application cosmology black holes. Thus, we ...

The cis – trans -isomerism of the propiolic acid monomer (HCC–COOH) is examined with linear Raman jet spectroscopy, yielding first environment-free vibrational band centres a higher-energy -rotamer beyond formic (HCOOH) in addition to all fundamentals and large number hot combination/overtone bands -conformer.

in this study, geometrical, gravimetrical and frictional properties of four common varieties of iranian canola seeds (namely: slm, hyola, okapi, orient), containing the mean moisture value of 6.5% (w.b.) were investigated. geometrical and gravimetrical properties included length, diameter, geometric mean diameter, sphericity, thousand seed mass, volume, true density, bulk density and porosity. ...

and his colleagues present a detailed and careful analysis of the arrangement of the heart and thoraco-abdominal organs in a large series of over one thousand autopsied patients.1 Their findings bear directly upon the controversy in which I was recently involved at the 3rd World Congress of Pediatric Cardiology and Cardiac Surgery. The controversy sessions took place on the last day of the Symp...

Nuclear isomers are the metastable excited states of nuclei. The can be categorized into a few classes including spin, seniority, K, shape and fission depending upon hindrance mechanisms. In this paper, we aim to present an overview seniority isomers, which is category related quantum number. discussion mainly based on concepts generalized seniority. Various aspects their whereabouts have been ...

The electron spin resonance spectra of 1-myristoyl-2-[n-(4,4-dimethyloxazolidine-N-oxyl)myristoyl]-sn- glycero-3-phosphocholine spin-label positional isomers (n = 6, 10, and 13) have been studied in oriented, fully hydrated bilayers of dimyristoylphosphatidylcholine, as a function of temperature and magnetic field orientation. The spectra have been simulated using a line-shape model which incor...
