Thermal properties of vortices on curved surfaces
(American Physical Society, 2018-01-16)
We use Monte Carlo simulations to study the finite temperature behavior of vortices in the XY model for tangent vector order on curved backgrounds. Contrary to naive expectations, we show that the underlying geometry does ...
Carbon and oxygen isotope compositions of some upper cretaceous–paleocene sequences in argentina and chile
(Taylor & Francis, 2001-01-06)
The Cretaceous-Paleocene (K-T) transition has been recorded in sedimentary carbonate rocks in northwestern Argentina and southern Chile. In the Yacoraite Basin, Argentina, this transition has been preserved in a 2 m thick ...

Lattice effects in the quasi-two-dimensional valence-bond-solid Mott insulator EtMe 3 P[Pd(dmit) 2] 2
(2014-01-10)
The organic charge-transfer salt EtMe3P[Pd(dmit)2]2 is a quasi-two-dimensional Mott insulator with localized spins S=1/2 residing on a distorted triangular lattice. Here we report measurements of the uniaxial thermal ...
Formation of AlCl by radiative association
(Oxford Univ Press, 2018-06-01)
The rate coefficient for the formation of aluminium monochloride, AlCl, from the radiative association of aluminium and chlorine atoms is estimated as a function of temperature. The coupling of the Al and Cl atoms through ...
Radiative association of P and Cl atoms
(Springer, 2020-05-30)
Thermal rate constants for the formation of PCl radical via radiative association have been estimated from potential energy curves and dipole moments calculated by accurate ab initio methods. The formation of PCl through ...
Influência dos aspectos geométricos das barras de aço no fator de concentração de tensão
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2021-03-12)
Steel reinforcement bars (rebars) have ribs to allow good adhesion between steel and concrete. However, the transition radius between the free surface and the transverse rib of the bars is an area of geometric discontinuity ...
