Problem Space Identification for Developing Virtual Reality Learning Environments

2021

Our study argues that the extant literature on virtual reality-based learning environments (VRLEs) currently lacks proper definitions and context descriptions for a problem space, which is fundamental for conducting design science research (DSR). Without properly conducted problem space identification, the most pivotal problems cannot be identified resulting solutions lacking validity and unreliable evaluations. This is a major challenge for the DSR in the educational field, but also for the research on VRLEs. The purpose of this paper is to introduce a novel DSR method to support rigorous problem space identification, which would allow rigorous and profound problem space analysis. The inst…

Thermomineral waters of Greece: geochemical characterization

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.

Azido and thiocyanato bridged dinuclear Ni(II) complexes involving 8-aminoquinoline based Schiff base as blocking ligands: Crystal structures, ferrom…

2020

Abstract The use of two 8-aminoquinoline-based tridentate N3-donor rigid Schiff base ligands (L1 and L2) with Ni(II) in the presence of the pseudohalides, NaN3 and NaSCN results in the crystallization of the two novel Ni(II) dimers: [Ni2(L1)2(µ1,1′-N3)2(N3)2] (1) and [Ni2(L2)2(µ1,3-NCS)2(NCS)2] (2). Both complexes are centrosymmetric Ni(II) dimers where the Schiff base ligands coordinate the octahedral Ni(II) centres in a mer configuration with one terminal and two bridging pseudohalide ligands in the remaining positions. Complex 1 shows Ni(II) ions connected by a double µ1,1′-N3− bridge whereas in complex 2 the Ni(II) ions are connected by a double µ1,3-NCS− bridge. The magnetic properties…

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…

Aprenentatge basat en projectes: aproximació a l'ensenyament de sistemes de potència de gas i vapor

2014

L’objectiu d’aquest treball és presentar l’experiència i els resultats derivats de l’aplicació del mètode d’aprenentatge basat en projectes (PBL) de l’assignatura de Termotècnia de la titulació d’Enginyeria Química de la Universitat del País Basc/Euskal Herriko Unibertsitatea. Després d’un anàlisi crític dels resultats acadèmics dels alumnes que aprenen motors tèrmics, s’observa que l’estratègia d’ensenyament-aprenentatge tradicional, basat en classes magistrals + classes d’aplicació en una llista d’exercicis (totalment acotats i amb una solució única), està fallant. Davant d’aquesta situació, es planteja un enfoc constructivista centrat en l’alumne perquè ell mateix construeixi el seu apre…

La relación entre las palabras clave aportadas por autores de artículos de revista y su indización en las bases de datos ISOC, IME e ICYT

2005

Se analizan las palabras clave proporcionadas por autores en sus artículos científicos y los descriptores asignados a dichos artículos en varias bases de datos para averiguar el papel que juegan esas palabras clave durante el proceso de indización de los mismos. Para ello, se seleccionaron 108 publicaciones periódicas repartidas proporcionalmente entre Ciencias Sociales y Humanidades (36 revistas), Ciencia y Tecnología (36) y Ciencias Médicas y de la Salud (36). De cada una de las 108 publicaciones se escogieron 10 artículos repartidos entre diferentes años, por lo que se trabajó con un total de 1080 que cumplían dos condiciones: poseer palabras clave y estar indizados en las bases de datos…
