Recently, the interest in studying pancreatic cancer mortality has increased due to its high lethality. In this work a detailed analysis of pancreatic cancer mortality in Spanish provinces was performed using recent data. ... -
Structurally oriented nano-sheets in Co thin films: changing their anisotropic physical properties by thermally-induced relaxation
Vergara Platero, José; Favieres Ruiz, Cristina ; Magén, César; Teresa, José María de; Ibarra, Manuel Ricardo; Madurga Pérez, Vicente (MDPI, 2017)
Artículo / Artikulua
We show how nanocrystalline Co films formed by separated oblique nano-sheets display anisotropy in their resistivity, magnetization process, surface nano-morphology and optical transmission. After performing a heat treatment ... -
Fiber optic sensors based on hybrid phenyl-silica xerogel films to detect n-hexane: determination of the isosteric enthalpy of adsorption
Echeverría Morrás, Jesús; Calleja, Ignacio; Moriones Jiménez, Paula ; Garrido Segovia, Julián José (Beilstein-Institut, 2017)
Artículo / Artikulua
We investigated the response of three fiber optic sensing elements prepared at pH 10 from phenyltriethoxysilane (PhTEOS) and tetraethylsilane (TEOS) mixtures with 30, 40, and 50% PhTEOS in the silicon precursor mixture. ... -
Normalization through invariants in n-dimensional Kepler problems
Meyer, Kenneth Ray; Palacián Subiela, Jesús Francisco; Yanguas Sayas, Patricia (Pleiades Publishing, 2018)
Artículo / Artikulua
We present a procedure for the normalization of perturbed Keplerian problems in n dimensions based on Moser regularization of the Kepler problem and the invariants associated to the reduction process. The approach allows ... -
Dynamics of axially symmetric perturbed Hamiltonians in 1:1:1 resonance
Carrasco, Dante; Palacián Subiela, Jesús Francisco; Vidal, Claudio; Vidarte, Jhon; Yanguas Sayas, Patricia (Springer, 2018)
