Numerical modeling of phase change materials using simusol software
(Pergamon-Elsevier Science Ltd, 2019-02-07)
Thermal storage systems with phase change materials offer a high density of energy with a moderate temperature variation as well as the possibility to keep the inner temperature within a comfort range. To achieve this goal, ...
Analytical expressions to estimate the effective piezoelectric tensor of a textured polycrystal for any crystal symmetry
(Elsevier Science, 2020-12)
This work introduces a set of analytical expressions that simplifies the procedure of obtaining closed-form formulas to estimate the effective piezoelectric properties of polycrystalline aggregates formed by crystals of ...
Iglesia y orden político en el cercano oriente medieval (siglos VII-X)Church and monarchy in medieval Near East (VII-X centuries)
(Centro de Estudios e Investigaciones Laborales, 2018-10)
A lo largo de la edad media, tanto la cristiandad latina como la bizantina asumieron Iglesia y monarquía como instituciones intrínsecamente vinculadas. Pero los cristianos de Siria, Iraq e Irán desarrollaron una relación ...
Photobleaching of camphorquinone during polymerization of dimethacrylate-based resins
(Elsevier, 2009-12-16)
Objective: The aim of this study was to compare the photobleaching rate of CQ in different dental resins. Methods: The photodecomposition rate of CQ/amine system in bis-GMA/TEGDMA, bis-EMA and UDMA polymerizing monomers ...
Sexually dimorphic expression of receptor-alpha in the cerebral cortex of neonatal Caiman latirostris (Crocodylia, Aligatoridae)
(Academic Press Inc Elsevier Science, 2012-11)
In mammals, estrogens have been described as endocrine and paracrine modulators of neuronal differentiation and synapse formation. However, the functional role of circulating estrogens and the distribution of estrogen ...
De las dos estéticas kantianas a la lógica de la sensación deleuzianaFrom the Two Kantian Aesthetics to the Deleuzean Logic of Sensation
(Universidad Nacional de Colombia, 2021-01)
Este artículo analiza la crítica de Gilles Deleuze a la dualidad kantiana de la estética. El autor atribuye la no-coincidencia entre la estética trascendental como teoría de la sensibilidad y la estética como teoría del ...
Photosynthesis, Resource Acquisition and Growth Responses of Two Biomass Crops Subjected to Water Stress
(Science Publishing Group, 2018-06)
This study compares photosynthesis, growth, 13C and 15N labelling patterns of two biomass crops (Arundo donaxL. and Panicum virgatum L.) grown under water stress in greenhouse conditions. Plants were exposed to three water ...
Optical performance of hybrid porous silicon-porous alumina multilayers
(American Institute of Physics, 2018-05)
In this work, we study the optical response of structures involving porous silicon and porous alumina in a multi-layered hybrid structure. We performed a rational design of the optimal sequence necessary to produce a high ...
Photocatalytic reactions of a nickel(II) annulene complex incorporated in polymeric structures
(Royal Society of Chemistry, 2014-10)
The photochemical reactions of the Ni(II) annulene complex, [NiII([5,7,12,14]-tetra methyl dibenzo[2,3- b:2,3-b,i][1,4,8,11]tetraaza[14]annulenate)], grafted into a poly(isobutylene-alt-maleate) backbone were investigated ...
Improving peak capacity in fast online comprehensive two-dimensional liquid chromatography with post-first-dimension flow splitting
(American Chemical Society, 2011-12)
The use of flow splitters between the two dimensions in online comprehensive two-dimensional (2D) liquid chromatography (LC × LC) has not received very much attention, in comparison with their use in 2D gas chromatography ...
