abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
In this paper we initiate systematic studies on the novel methods needed for quantitative scientific studies of the emerging new forms of energy, by using as a representative example the new combustible gas called AquaFuel, discovered and patented by William H. Richardson, jr., whose rights are now owned by Toups Technology Licensing, Inc. (TTL), of Largo, Florida. In essence, AquaFuel is a new...
In order to resolve a long-standing discrepancy of some 30 standard deviations between the two most precise previously reported values of the γ-ray energies in the (38)Cl decays, we have undertaken a new precision measurement of the decay energies using a variety of different sources for energy calibration. The deduced energies from the present work are 1642.668 ± 0.010 and 2167.395 ± 0.010 keV...
We consider the behavior of particles at ultra relativistic energies, for both the Klein-Gordon and Dirac equations. We observe that the usual description is valid for energies such that we are outside the particle’s Compton wavelength. For higher energies however, both the Klein-Gordon and Dirac equations get modified and this leads to some new effects for the particles, including the appearan...
A theoretical model for predicting the free energy of binding between anthracycline antibiotics and DNA was developed using the electron density functional (DFT) and molecular mechanics (MM) methods. Partial DFT-ESP charges were used in calculating the MM binding energies for complexes formed between anthracycline antibiotics and oligodeoxynucleotides. These energies were then compared with exp...
We present new measurements of heavy cosmic-ray nuclei at high energies performed during the first flight of the balloon-borne cosmic-ray experiment CREAM (Cosmic-Ray Energetics And Mass). This instrument uses multiple charge detectors Preprint submitted to Elsevier 12 August 2008 and a transition radiation detector to provide the first high accuracy measurements of the relative abundances of e...
the interaction between proteins and membranes has an important role in biological pro-cesses.we have calculated energies of interaction between melittin and dmpc bilayer in differenttemperatures. we have used the charmm software for md simulation under the canonical (n,v, e) ensemble at different temperatures. the computations have shown that water moleculeshave more penetration into the bilay...
