Continuous and discontinuous nominal expressions in flexible (or “free”) word order languages: Patterns and correlates
2020
AbstractThis study explores continuous and discontinuous word order patterns of multi-word nominal expressions in flexible word order languages (traditionally referred to as “free word order” or “non-configurational” languages). Besides describing syntagmatic patterns, this paper seeks to identify any functional or other correlates that can be associated with different word orders. The languages under investigation are a number of Australian languages as well as Vedic Sanskrit, all of which have long been known for their syntagmatic flexibility. With respect to continuous order, evidence from several of these languages suggests that default ordering is primarily governed by functional templ…
Spatio-temporal deixis and cognitive models in early Indo-European
2018
AbstractThis paper is a comparative study based on the linguistic evidence in Vedic Sanskrit and Homeric Greek, aimed at reconstructing the space-time cognitive models used in the Proto-Indo-European language in a diachronic perspective. While it has been widely recognized that ancient Indo-European languages construed earlier (and past) events as in front of later ones, as predicted in the Time-Reference-Point mapping, it is less clear how in the same languages the passage took place from this ‘archaic’ Time-RP model or non-deictic sequence, in which future events are behind or follow the past ones in a temporal sequence, to the more recent ‘post-archaic’ Ego-RP model that is found only fr…
Design of nonionic surfactants for supercritical carbon dioxide
1996
Interfacially active block copolymer amphiphiles have been synthesized and their self-assembly into micelles in supercritical carbon dioxide (CO 2 ) has been demonstrated with small-angle neutron scattering (SANS). These materials establish the design criteria for molecularly engineered surfactants that can stabilize and disperse otherwise insoluble matter into a CO 2 continuous phase. Polystyrene- b -poly(1,1-dihydroperfluorooctyl acrylate) copolymers self-assembled into polydisperse core-shell-type micelles as a result of the disparate solubility characteristics of the different block segments in CO 2 . These nonionic surfactants for CO 2 were shown by SANS to be capable of emulsifying u…

Partitioning of macrocyclic compounds in a cationic and an anionic micellar solution: a small-angle neutron scattering study.
2004
Following a previous investigation on partitioning of some macrocycle compounds in sodium dodecyl sulfate (SDS) and dodecyltrimethylammonium bromide (DTAB) aqueous solutions and their effect on the micellar structure, a small-angle neutron scattering (SANS) study has been performed at fixed surfactant content (0.20 mol/L) and varying macrocycle concentrations from 0.20 up to 1.0 mol/L. Conductivity measurements have been also performed in order to evaluate the effect of the presence of macrocycles on the critical micellar concentration (cmc) of the two surfactants. SANS experimental data were fitted successfully by means of a core-plus-shell monodisperse prolate ellipsoid model. It has been…
La confrontación partidista española a propósito de América Latina
2021
América Latina ha sido desde siempre objeto de controversia en España, aunque últimamente con mayor intensidad se ha convertido en materia de utilización partidista, especialmente por parte de un bloque conservador que se esfuerza en convertir hechos y procesos latinoamericanos en elementos de confrontación política interna española. También las izquierdas hispanas tienen presente a América latina en su acción política, y padecen una elevada desinformación, mientras mantienen clichés de otra época. El artículo atiende a tres casos en la confrontación derecha/izquierda de los últimos tiempos: Venezuela, ariete conservador contra el Gobierno de Pedro Sánchez; México, como excitante del nacion…

Optimization of flat area coverage under connectivity constraint in wireless sensor networks
2022
A wireless sensor network consists of a set of small autonomous units that interact via a network built by their communication modules. They observe their environment, capture information, then manage this information according to their computing and/or storage capacity. To effectively accomplish their task(s), they need to cover as much of the area of interest as possible. It is therefore essential to quantify the quality of their coverage. In this thesis, we therefore seek to best cover an area of interest, with a precise number of sensors. While taking into account the possible overlaps between sensors, we first deploy in a zone of regular dimensions and evaluate the exact coverage using…
