Regarding TDS concentrations collected waters can be subdivided into low salinity (up to 1.5 g/L) brackish (up to 20 g/L) and saline (up to 43 g/L). The medium high salinities can be justified by mixing with sea water and/or strong waterrock interaction processes. Isotope composition of O and H ranges from 12.7 to +2.7 ‰ SMOW and from 91 to +12 ‰ SMOW respectively and is generally comprised between the Global Meteoric Water Line and the East Mediterranean Meteoric Water Line. Only few water samples show a positive shift for δ18O possibly related to high temperature waterrock interaction processes.

Moreover the majority of them is found along the coast as well as in islands of the Aegean Sea and thus thermal water is often brackish to saline due to marine intrusion into costal aquifer. In the present study almost 300 thermal and cold mineral water samples were collected along the Hellenic territory with their physicochemical parameters (temperature pH electrical conductivity and Eh) and the amount of bicarbonates (titration with 0.1N HCl) being determined in situ. Additionally gases found either in free or dissolved phase were sampled. Both water and gas samples were analysed at the INGVPa laboratories for major ions (Ion Chromatography) silica (Inductively Coupled Plasma Optical Emission Spectrometry) chemical composition of free and dissolved gases (Gas Chromatography) water isotopes (O and H) and carbon and helium isotopes of free and dissolved gases (Mass Spectrometry). The temperature of the investigated waters ranges from 6.5 to 98°C pH from 1.96 to 11.98 whilst Total Dissolved Solids (TDS) from 0.06 to 43 g/L. Based on the temperature parameter waters can be divided into four groups: i) cold (&lt0.5 913000 μmol/mol) are the prevailing gas species found in the studied sites.

Field rules and bias in random surveys with quota samples : an assessment of CIS surveys

2018

Surveys applying quota sampling in their final step are widely used in opinion and market research all over the world. This is also the case in Spain, where the surveys carried out by CIS (a public institution for sociological research supported by the government) have become a point of reference. The rules used by CIS to select individuals within quotas, however, could be improved as they lead to biases in age distributions. Analysing more than 545,000 responses collected in the 220 monthly barometers conducted between 1997 and 2016 by CIS, we compare the empirical distributions of the barometers with the expected distributions from the sample design and/or target populations. Among other …

Filiación y parejas homosexuales en Italia

2018

El presente trabajo se ocupa del modo en que en Italia, donde no se reconoce la adopción de menores por parejas homosexuales, ni la posibilidad de que las mismas puedan acceder a la reproducción asistida, ha surgido lo que podríamos denominar un “shopping médico-jurídico”, en relación a la posibilidad de someterse en el extranjero a prácticas de inseminación artificial heteróloga con adopción del menor por parte del partner o con inscripción del acta de nacimiento conforme al Derecho extranjero que reconoce al menor como hijo de la pareja. The paper deals with the forms with which in Italy, where it is not recognized the adoption of minors for homosexual couples nor the possibility for thes…

Different approaches to marriage downgrading : from an anti-elusive measure to an antidiscriminatory claim

2021

The essay focuses on the different mechanisms of marriage downgrading. Given the principle of ?cross-border continuity? of statuses, limits to this continuity are sometimes admitted and they are placed through downgrading mechanisms. That can occour in the case of same-sex marriages transcription in a Member State which does not allow such marriages, but which does allow samesex registered partnerships. Downgrading mechanism has an anti-elusive function, but it is not without problems in terms of discrimination on the grounds of sexual orientation. A different approach is taken in the case of an opposite-sex couple requesting the downgrading of their marriage, celebrated before the Member S…

Pre-marital and pre-unional financial agreements and their circulation in the context of the new EU regulations 2016/1103 and 2016/1104

2021

Regulations (EU) 2016/1103 and 2016/1104 provide spouses and partners with the possibility to conclude agreements for the organization of their property regime but do not detail their content and structure. Moreover, while the possibility to conclude those agreements even prior to the marriage or the conclusion of a registered partnership is a valuable innovation in comparison with other European Regulations in family matters, some choices made by the European legislator on applicable law will likely be source of inconveniences. Furthermore, as for their recognition and enforcement in the participating Member States ? which will be based on the same rules enacted for decisions, authentic in…

Jurisdiction by connection and proper administration of justice under eu regulations 1103/2016 and 1104/2016

2021

The author analyses the rules of jurisdiction by connection set by Articles 4 and 5 of Regulations No. 1103 and 1104 of 2016 in matters of property regimes of transnational couples, taking into account the objective of proper administration of justice pursued within EU Civil judicial cooperation. The Twin Regulations provide for appropriate procedural tools to facilitate concentration of jurisdiction before the courts of the same Member State, establishing an important role for the choice-of-court agreement, especially where property regime issues arise in connection with a matrimonial case or a partnership dissolution case. As we wait for the implementation of these rules by national and E…

Stable isotopes covering 96-7 ka BP from stalagmite CM (Santo Tomas Cave, Cuba)

2020

We present a new speleothem trace element and stable isotope record, which extends previous paleoclimate evidence from Cuban speleothems to the last 96 ka. Stable isotope samples were micromilled at a resolution of 0.10-0.33mm, and measured using an IRMS equipped with a Gasbench. Line scans of Element/Calcium ratios of the speleothem were measured by laser ablation ICPMS and were reduced to the resolution of the stable isotope records.

2010

A suitable extraction and purification method for the simultaneous liquid chromatography-mass spectrometry (LC-MS) determination of five mycotoxins, three type A, diacetoxyscirpenol (DAS), T-2 toxin (T-2) and HT-2 toxin (HT-2), and two type B-trichothecenes, deoxynivalenol (DON) and nivalenol (NIV), has been optimised using a modified "Quick Easy Cheap Effective Rugged and Safe" (QuEChERS) method. Different solvents were studied in the extraction procedure to obtain better recoveries, which ranged from 86 to 108%, using a 85/15 (v/v) mixture of methanol/acetonitrile. The values obtained for recovery, repeatability and reproducibility of the optimized method are in agreement with Commission …

A distributed real-time data prediction and adaptive sensing approach for wireless sensor networks

2018

International audience; Many approaches have been proposed in the literature to reduce energy consumption in Wireless Sensor Networks (WSNs). Influenced by the fact that radio communication and sensing are considered to be the most energy consuming activities in such networks. Most of these approaches focused on either reducing the number of collected data using adaptive sampling techniques or on reducing the number of data transmitted over the network using prediction models. In this article, we propose a novel prediction-based data reduction method. furthermore, we combine it with an adaptive sampling rate technique, allowing us to significantly decrease energy consumption and extend the …
