In the present work, a study of thermoelastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient and non-uniform internal pressure is carried out. The formulation is based on first-order shear deformation theory (FSDT), which accounts for the transverse shear. The governing equations, derived using minimum total potential energy principle, are solved, usi...
New therapies are urgently needed against melanoma, one of the most aggressive tumors. Melanoma cells are resistant to the antifolate methotrexate (MTX), since MTX is taken up by the folate receptor-α (FRα), sequestered in melanosomes and exported out of the cell. The bisphosphonate zoledronic acid (ZOL) is active in several non-skeletal tumors; however, its antitumoral activity is hampered by ...
The inverse sandwich Ca-C8H8-Ca is predicted to be an open-shell singlet state. Since the C8H8 ligand prevents the spin-up and spin-down electrons of different calcium atoms from forming Ca-Ca bonds, the spin-coupling electrons lead to a singlet diradical character. The metal-ligand interaction contributes to the stability of Ca-C8H8-Ca against dissociation and isomerization. For the coordinati...
Hybridized porous coordination polymers (PCPs) are synthesized through epitaxial growth or ligand replacement. Whereas epitaxial growth on the core crystal leads to a sandwich type PCP, ligand replacement near the surface of core crystal results in a core-shell type PCP.
MOTIVATION Giving a meaningful representation of a pedigree is not obvious when it includes consanguinity loops, individuals with multiple mates or several related families. RESULTS We show that finding a perfectly meaningful representation of a pedigree is equivalent to the interval graph sandwich problem and we propose an algorithm for drawing pedigrees.
SUMMARY This Report considers theoretically and experimentally some of the problems associated with the flexure of two unequal cylindrical shells Joined by a conical frustum. Particular attention is given to the determination of the overall flexursl stiffness of the conical frustum and to structural design considerations associated with the provision of a separation capability in the frustum. T...
