© 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 ...

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), ...

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 ...

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 ...

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 ...

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. ...
