The settling of fine cohesive powders
(IOP Publishing Ltd., 2001-05-01)
We investigate the settling of an initially fluidized bed of a fine cohesive powder. Experimental results on the sedimentation rate cannot be fitted by theoretical and empirical equations existing in the literature and ...

Left-handed-media simulation and transmission of EM waves in subwavelength split-ring-resonator-loaded metallic waveguides
(American Physical Society, 2002-10-28)
At microwave frequencies, hollow metallic waveguides behave in certain aspects as a “one-dimensional plasma.” This feature will be advantageously used for simulating the propagation of electromagnetic (EM) waves in left-handed ...

Curcumin as a DNA Topoisomerase II Poison
(Taylor & Francis Open Access, 2003)
Curcumin, the major active component of the spice turmeric, is recognised as a safe compound with great potential for cancer chemoprevention and cancer therapy. It induces apoptosis, but its initiation mechanism remains ...

Boundary Element Analysis of Three-Dimensional Exponentially Graded Isotropic Elastic Solids
(Tech Science Press, 2007)
A numerical implementation of the Somigliana identity in displacements for the solution of 3D elastic problems in exponentially graded isotropic solids is presented. An expression for the fundamental solution in ...

A Practical Synthesis of Enantiopure 4,5-Dihydroisoxazole-5-carboxylic Acids
(2005)
The 1,3-dipolar cycloaddition of a variety of aromatic and aliphatic nitrile oxides to 2,5-trans-2,5-diphenylpyrrolidine derived acrylamide and cinnamamide efficiently affords the corresponding 4,5-dihydroisoxazole-5- ...

Physico-chemical modeling of positive corona discharge in carbon dioxide
(Institute of Electrical and Electronics Engineers (IEEE), 2010)
Positive wire-to-cylinder corona discharge in pure CO2 has been simulated using a model that includes elementary plasma processes (ionization, electron attachment and detachment, ion recombination, etc.) and chemical ...

On the use of algorithms to discover motifs in DNA sequences
(IEEE, 2011)
Many approaches are currently devoted to find DNA motifs in nucleotide sequences. However, this task remains challenging for specialists nowadays due to the difficulties they find to deeply understand gene regulatory ...
