Variations of geomagnetic cutoff rigidity in the southern hemisphere close to 70°W (South-Atlantic Anomaly and Antarctic zones) in the period 1975–2010
(Elsevier Ltd, 2019)
© 2018 COSPARWe report the existence of rapid variations in (effective) geomagnetic cutoff rigidity (Rc) between the equatorial and Antarctic zones adjacent to the Andes Mountains, revealed by the variation rate of geomagnetic ...
Rigid and semi rigid polyurethane resins: a structural investigation using DMA, SAXS and Le Bail method
(Elsevier BVAmsterdam, 2014-10)
Two different types of polyurethane (PU) resins were synthesized with pre-polymer/polyol (-NCO/-OH) mass proportions of 1:1 (Rigid PU) and 1:1.5 (Semi rigid PU). Based on the results from Dynamic Mechanical Analysis (DMA), ...

Spacelike biharmonic general helices with timelike normal in the lorentzian group of rigid motions E(2)
Lesser Toes Proximal Interphalangeal Joint Fusion in Rigid Claw Toes
Treatment of rigid claw toe is still subject to discussion and evolution. Arthrodesis or arthroplasty of the PIPJ is apparently the most reliable procedure. K wire seems be the most reliable way to solve this clinical ...
A Keynesian model of nominal wage rigidity
(Sociedade Brasileira de Econometria, 1990-04-01)
We present a Model that reflects Keynes' intuition concerning nominal wage rigidity: workers like to keep their relative status on society. Several results are presented, including the analysis of the influence of risk ...
The Nash–Moser theorem of Hamilton and rigidity of finite dimensional nilpotent Lie algebras
(Elsevier Science, 2017-09)
We apply the Nash–Moser theorem for exact sequences of R. Hamilton to the context of deformations of Lie algebras and we discuss some aspects of the scope of this theorem in connection with the polynomial ideal associated ...
Global weak solutions for the two-dimensional motion of several rigid bodies in an incompressible viscous fluid
We consider the two-dimensional motion of several non-homogeneous rigid bodies immersed in an incompressible non-homogeneous viscous fluid. The fluid, and the rigid bodies are contained in a fixed open bounded set of R2. ...
