La reproducción asistida y la filiación. Especial referencia al caso de las parejas de mujeres homosexuales
2018
This paper analyses, in general, the evolution that has had the art. 7.3 LTRHA since its introduction by the Act 3/2007, 15 march. In that way, it shows which has been the legislator´s solution about the use of assisted reproduction tecniques by homosexual women couples. Likewise, it studies which resolutions on the matter have been more relevant in the last years. All this, to set out the legislator´s failure and the need to reformulate the filiation regime in face of the challenge that assisted reproduction implies.
Interactions surface continentale/atmosphère : l'expérience HAPEX-Sahel
1994
L'évolution saisonnière des termes du bilan radiatif, du bilan d'énergie et la production primaire d'une savane humide d'Afrique de l'Ouest (Lamto, Côte d'Ivoire) a été suivie dans le cadre du programme SAvanes à Long Terme (SALT). Ces données ont permis de développer un modèle de simulation des échanges surface/atmosphère en savane humide, basé sur les relations fonctionnelles existant entre la production et la phénologie de la savane d'une part, et les bilans d'énergie et hydrique de ce type de surface d'autre part. Ce modèle est issu du couplage de deux sous-modèles fonctionnant au pas de temps journalier et utilisant des variables climatiques standard en entrée : le modèle de bilan d'én…
Implementation of a Management System for Prosumer Energy Storage Scheduling in Smart Grids
2020
Scheduling of energy storage systems of distributed generation is a key element for optimal renewable energy sources (RES) exploitation in smart grids, demand side response strategies implementation and prosumers interaction with Distribution System Operators (DSOs). In this context, this paper presents the implementation of a management system for energy storage scheduling, which allows taking appropriate account of the storage system behavior in real cases. To properly consider the real system operation, the employed battery model is modified, in order to include also the hysteresis phenomena in state of charge estimation in both charging and discharging operation. The validation of the p…
Electrical power production from low-grade waste heat using a thermally regenerative ethylenediamine battery
2017
Abstract Thermally regenerative ammonia-based batteries (TRABs) have been developed to harvest low-grade waste heat as electricity. To improve the power production and anodic coulombic efficiency, the use of ethylenediamine as an alternative ligand to ammonia was explored here. The power density of the ethylenediamine-based battery (TRENB) was 85 ± 3 W m−2-electrode area with 2 M ethylenediamine, and 119 ± 4 W m−2 with 3 M ethylenediamine. This power density was 68% higher than that of TRAB. The energy density was 478 Wh m−3-anolyte, which was ∼50% higher than that produced by TRAB. The anodic coulombic efficiency of the TRENB was 77 ± 2%, which was more than twice that obtained using ammon…

An initial comparative map of copy number variations in the goat (Capra hircus) genome
2010
Abstract Background The goat (Capra hircus) represents one of the most important farm animal species. It is reared in all continents with an estimated world population of about 800 million of animals. Despite its importance, studies on the goat genome are still in their infancy compared to those in other farm animal species. Comparative mapping between cattle and goat showed only a few rearrangements in agreement with the similarity of chromosome banding. We carried out a cross species cattle-goat array comparative genome hybridization (aCGH) experiment in order to identify copy number variations (CNVs) in the goat genome analysing animals of different breeds (Saanen, Camosciata delle Alpi,…
Asiakkuudenhallinta ja sen hyödyt sekä haasteet palveluyrityksissä
2015
Asiakkuudenhallinta hyödyttää yrityksen liiketoimintaa useilla eri tavoilla. Jatkuvasti kasvavan palvelusektorin yrityksille se luo paljon lisäarvoa asiakas-suhteiden hallinnan ja kehittämisen muodossa. Tässä kandidaatin tutkielmassa on tarkasteltu asiakkuudenhallinnan hyödyntämistä palveluyrityksissä. Lisäk-si tutkielmassa on arvioitu asiakkuudenhallinnan haasteita ja mahdollisia on-gelmia palveluyrityksissä ja palvelutuotannossa yleisesti. Aluksi on tarkasteltu asiakkuudenhallintaa yleisellä tasolla, määritelty keskeiset käsitteet, kuvattu asiakkuudenhallinnan yleiset vaiheet ja prosessit sekä tarkasteltu asiakkuu-denhallinnan toteuttamisessa hyödynnettäviä tietojärjestelmiä.

Integrated annual calcium carbonate production of planktic calcifiers in the North Pacific from the R/V Kilo Moana cruise KM1712
2022
This dataset compiles the estimates of annual CaCO3 production, including the upper and lower limits of the estimates, for the 4 planktic calcifying groups considered in the study, the pteropods (mg/m²/yr), the heteropods (mg/m²/yr), the foraminifers (mg/m²/yr) and the coccolithophores (mg/m²/yr). The estimates derived from the living standing stocks of these 4 groups of organisms collected in the North Pacific between Hawaii and the Gulf of Alaska during the R/V Kilo Moana cruise KM1712 in August 2017. R code was used to calculate the integrated annual CaCO3 production for the different organisms, including the upper and lower limits (Gray, 2022).
On the limits to the long-period method in classical economics. A note
2001
On a first reading of Theory of Production, Kurz & Salvadori (1995) appear to confine the empirical domain of the long-period models of the classical theory of value and distribution to stationary economies with non-constant returns to scale and to growing economies with constant returns to scale. Such a reading is shown to be untenable since it merges the two levels of exploring the extension of a model and of testing a theoretical hypothesis. Conversely, the way Kurz & Salvadori tackle the problems of price dynamics and returns to scale in growing economies is shown to be compatible with what appears to be Sraffa's (implicit) strategy of research.
Characterisation of clayey raw materials for ceramic manufacture in ancient Sicily
2011
Abstract It is well known that mineralogical, petrographic and chemical analyses can successfully support provenance studies of archaeological ceramics. The characterisation of a ceramic paste, the assessment of its technology of production and its provenance assignment related to a specific production centre or to a geographical and/or compositional space, are all tasks that can be performed even more accurately if the clayey raw materials used in pottery production are also studied. For that reason the identification of the clay deposits exploited in a given ceramic workshop often plays a key role in the archaeometric reconstruction of the production cycle where geology, mineralogy, petro…
