From almost (para)-complex structures to affine structures on Lie groups
(Springer, 2018-01)
Let G= H⋉ K denote a semidirect product Lie group with Lie algebra g= h⊕ k, where k is an ideal and h is a subalgebra of the same dimension as k. There exist some natural split isomorphisms S with S2= ± Id on g: given any ...
Structural analysis
A structure, as it relates to civil engineering, is a system of interconnected members used to support
external loads. Structural analysis is the prediction of the response of structures to specified
arbitrary external ...
Discontinuous continuity: Structural change and its (divergent) meanings in Latin American structuralism and neo-structuralism
(Universidad Nacional de Colombia, 2020-06)
This paper analyses the continuities and discontinuities regarding the concept of structural change in Latin American structuralism and neo-structuralism and considers the global context in which these ideas and their ...
The effectiveness of the gyroscopic effect for controlling structural vibrations
(Taylor & Francis Ltd, 2021-07)
It is well known that seismic and wind induced vibration is an important issue in structural performance. To mitigate the problem of structural vibrations, many methodologies have been proposed and implemented. In this ...
Crystal structures of BnSP-7 and BnSP-6, two Lys49-phospholipases A(2): quaternary structure and inhibition mechanism insights
(Elsevier B.V., 2003-11-21)
Phospholipases A(2) are components of Bothrops venoms responsible for disruption of cell membrane integrity via hydrolysis of its phospholipids. A class of PLA(2)-like proteins has been described which despite PLA(2) ...
Experimental Validation of the Structural Fuse Concept
(2008-06-30)
Seismic design relies on inelastic deformations through hysteretic behavior. However, this translates into damage on structural elements, permanent system deformations following an earthquake, and possibly high cost for ...
Las ciencias de la educación en el contexto interdisciplinar: una justificación epistemológica
Presupuesto de partida que sustenta la argumentación del trabajo: Las llamadas Ciencias de la Educación sólo son explicables y comprensibles si se constituyen y funcionan como sistema. Trato de construir la a razón teórica ...
