A constructive approach of invariants of behavior laws with respect to an infinite symmetry group – Application to a biological anisotropic hyperelas…
2014
Abstract In this paper, six new invariants associated with an anisotropic material made of one fiber family are calculated by presenting a systematic constructive and original approach. This approach is based on the development of mathematical techniques from the theory of invariants: • Definition of the material symmetry group. • Definition of the generalized Reynolds Operator. • Calculation of an integrity basis for invariant polynomials. • Comparison between the new (constructed) invariants and the classical ones.
Rapid shifting of a deep magmatic source at Fagradalsfjall volcano, Iceland
2022
AbstractRecent Icelandic rifting events have illuminated the roles of centralized crustal magma reservoirs and lateral magma transport1–4, important characteristics of mid-ocean ridge magmatism1,5. A consequence of such shallow crustal processing of magmas4,5 is the overprinting of signatures that trace the origin, evolution and transport of melts in the uppermost mantle and lowermost crust6,7. Here we present unique insights into processes occurring in this zone from integrated petrologic and geochemical studies of the 2021 Fagradalsfjall eruption on the Reykjanes Peninsula in Iceland. Geochemical analyses of basalts erupted during the first 50 days of the eruption, combined with associate…
The Ghost of the Hawk: Top Predator Shaping Bird Communities in Space and Time
2021
Despite the wide recognition that strongly interacting species can influence distributions of other species, species interactions are often disregarded when assessing or projecting biodiversity distributions. In particular, it remains largely uncharted the extent to which the disappearance of a keystone species cast repercussions in the species composition of future communities. We tested whether an avian top predator can exert both positive and negative effects on spatial distribution of other species, and if these effects persist even after the predator disappeared. We acquired bird count data at different distances from occupied and non-occupied nests of Northern goshawks Accipiter genti…
Flow resistance of overland flow on a smooth bed under simulated rainfall
2020
In this paper a recently theoretically deduced flow resistance equation, based on a power-velocity profile, was tested using laboratory measurements by Yoon and Wenzel for an overland flow on a smooth bed under rainfall. These measurements of the Darcy-Weisbach friction factor, corresponding to a wide range of the flow Reynolds number (191–5700), were carried out for an overland flow under a simulated rainfall characterized by different intensity values ranging from 13 to 381 mm h−1. At first, the available measured values of flow velocity, water depth, cross sectional area, wetted perimeter and bed slope were used to calibrate the relationship between the velocity profile parameter Γ, the …
Negotiator and arbitrator: The activity of the Regent Melchor Sisternes during the Sardinian Parliament of 1677-1678
2018
Durante la Edad Moderna, el reino de Cerdeña contó con una importante institución propia de carácter representativo: el Parlamento. A diferencia de lo que ocurría en las Cortes de los reinos peninsulares de la Corona de Aragón, en Cerdeña estas nunca fueron presididas por los monarcas, quienes delegaban esa tarea en sus virreyes. Este trabajo analiza las funciones desempeñadas por el regente de la Cancillería de Cerdeña durante el transcurso de las sesiones parlamentarias. La particularidad de que el Parlamento fuera presidido por el virrey confería a los regentes de la Cancillería un papel del que no gozaron en las Cortes de los reinos peninsulares, por tanto, se convertían en una figura p…
"Kumpi on vaarallisempaa, porno vai romanttinen viihde?": Fifty Shades Of Grey -trilogian vastaanotto ja sen vaikutukset nykykulttuurissa
2016
Opinnäytetyö tutkii Fifty Shades of Grey -trilogiaa reseptiotutkimuksen kautta. Tutkielma analysoi pääasiassa internetissä julkaistuja lukijoiden tekstejä ja muita vastaanottoa käsitteleviä tekstejä. Tutkielma pyrkii myös selvittämään millainen vaikutus trilogialla on nykykulttuuriin ja sen erotisoitumiseen.
José Vergara Gimeno y la retratística valenciana en el siglo XVIII
2003
José Vergara (1726-1799) fue el fundador de la Academia de San Carlos, junto a su hermano Ignacio y a otros artistas valencianos, es el introductor de una renovación en el panorama artístico valenciano, que se plasmará en la redecoración de las iglesias valencianas, con complejos programas iconográficos al fresco y en los lienzos de altar. Sin embargo, uno de los aspectos inéditos de este artista es su pintura de retrato, en este artículo se pretende estudiar algunas de sus obras, la mayoría de ellas inéditas, con el fin de aportar una nueva visión de este artista de la segunda mitad del siglo dieciocho.
