Compact two-electron wave function for bond dissociation and Van der Waals interactions: A natural amplitude assessment
2014
Electron correlations in molecules can be divided in short range dynamical correlations, long range Van der Waals type interactions and near degeneracy static correlations. In this work we analyze for a one-dimensional model of a two-electron system how these three types of correlations can be incorporated in a simple wave function of restricted functional form consisting of an orbital product multiplied by a single correlation function $f(r_{12})$ depending on the interelectronic distance $r_{12}$. Since the three types of correlations mentioned lead to different signatures in terms of the natural orbital (NO) amplitudes in two-electron systems we make an analysis of the wave function in t…
Optical Remote Sensing in Urban Environments
2016
International audience; Cities today face a variety of issues: attractiveness and economic development, living conditions and urban redevelopment, the quality of life of citizens and the environmental conditions of the urban system as a whole. These challenges reflect the situations in urban territories where the economic development and population growth required for stabilizing the urban system come into conflict with the promotion of esthetic urban improvements appropriate for social cohesion and ensuring the safety of users while guaranteeing a reduction of the environmental impact caused by urban spread [WGI 14, WEB 15, MAC 07, WIL 11]. The process of urbanization, which has significan…
Développement territorial soutenable: l'approche des libertés et ses conséquences pour les politiques d'attractivité
2014
Moving from the concepts of territory as a social construct and of development as the progressive, dynamic fulfilment of self-established goals, the paper aims to show how a genuine strategy of development helps building up a sustainable attractiveness. To achieve this goal, the paper first investigates the accuracy of the Nation Brand Index as a signal of the territorial attractiveness, positive or negative, in a long term perspective. Second, the pertinence of the freedom approach to development in order to fully integrate the sustainability issues is enlightened. Finally, the two models are tied together, thus allowing the mutual links and synergies to appear and corroborating the idea t…
The relevance of corporate social responsibility for a sustainable human resource management: An analysis of organizational attractiveness as a deter…
2012
Corporate Social Responsibility (CSR) has become a central issue of business management in recent years. This study aims to add to the literature by pointing out the relevance of CSR for a Sustainable Human Resource Management (HRM). In particular this research investigates job seekers’ perceptions of CSR. The paper focuses on the importance of CSR with in the process of selecting potential employers by analyzing the impact of four different CSR-dimensions upon organizational attractiveness. To address this issue, a policy-capturing study was conducted. Generally the paper provides evidence that each aspect of CSR has a specific effect on organizational attraction. Referring to Sustainable …
The Sustainability of Cruise Tourism Onshore: The Impact of Crowding on Visitors’ Satisfaction
2019
The sustainability of cruise tourism has been questioned in relation to its negative effects on ports of call, among which crowding has recently become more pronounced. However, an understanding of how crowdedness influences cruise tourists&rsquo
Sex differences in mate preferences across 45 countries: a large-scale replication
2020
Considerable research has examined human mate preferences across cultures, finding universal sex differences in preferences for attractiveness and resources as well as sources of systematic cultural variation. Two competing perspectives-an evolutionary psychological perspective and a biosocial role perspective-offer alternative explanations for these findings. However, the original data on which each perspective relies are decades old, and the literature is fraught with conflicting methods, analyses, results, and conclusions. Using a new 45-country sample (N = 14,399), we attempted to replicate classic studies and test both the evolutionary and biosocial role perspectives. Support for unive…
The Garden and Landscape as an Interdisciplinary Resource Between Experimental Science and Artistic-Musical Expression: Analysis of Competence Develo…
2020
The garden is a major educational resource that can be used for all areas of knowledge from an interdisciplinary perspective as it reflects the complexity and interactions of the natural environment. This research was carried out in the academic years 2017-2018 and 2018-2019 with 418 participants of from the second, third, and fourth year of the Degree in Primary Education at the University of Valencia. The use of the garden and the landscape is analyzed as a non-formal context for training primary school teachers through sensory experiences that contribute to the development of scientific and artistic competencies. The study focused on the relationship between natural sounds and emotions t…
SVET, AFM and AES study of pitting corrosion initiated on MnS inclusions by microinjection
2003
As pitting is a random phenomenon, it is difficult to predict where a pit will appear on the surface and consequently the use of local probes is rendered difficult. In this work, a new method to study pitting corrosion on a MnS inclusion on 316L stainless steel is proposed. It consists in modifying locally the chemistry in its vicinity by injecting with a microcapillary an aggressive solution of NaCl, H2SO4 or HCl. Once a pit appears, scanning vibrating electrode technique (SVET) is used to follow the current fluctuations over and around the pit when the metal is polarized at a passive potential. In another series of experiments the effect of local activation of MnS inclusion was studied ex…
Ģeogrāfiskās telpas sociālā konstruēšana: Austrumeiropas (vai Orienta) konceptualizācijas piemērs
2017
Mentālās kartes ir neatdalamā daļa no mūsu domāšanas. Mentālās kartes ietekmē cilvēku subjektīvās vēsturiskās, ģeogrāfiskās un politiskās telpas veidošanu. Šajā darbā es aprakstīšu, kā ar mentālo karšu palīdzību laikmetā no 18.gs. Rietumeiropā aizsākās Austrumeiropas priekšstata veidošanas vēsture, kura attīstība tiks izskatīta līdz mūsdienām. Šī jautājuma noskaidrošanai, par pamatu pielietoju L. Vulfa grāmatu “Izgudrojot Austrumeiropu”, A. Apelbauma “Dzelzs priekškars”, H. Lefevra “Telpas konstruēšana”.
Relationships between the Impedance of Oxide Scales on Martensitic and Austenitic Steels and Corrosion Rate in Liquid Lead-Bismuth Eutectic
2004
Abstract The impedance properties (resistance and capacitance) of oxide scales on the martensitic/ferritic steel HT-9 and austenitic stainless steel Type 316L (UNS S31603) were examined during immersion in lead-bismuth eutectic (LBE) using a technique similar to electrochemical impedance spectroscopy. These scales were created by preoxidizing the samples in an air/water vapor environment at 800°C for various times prior to immersion in LBE. Calculation of oxide conductivity for samples immersed in LBE at 200°C for 200 h yielded σHT9 ≈ 4 × 10−7 (Ω × cm)−1 while σ316 ≈ 3 × 10−8 (Ω × cm)−1. The influence of temperature alone gave the anticipated Arrhenius behavior with Ea equal to 0.12 eV, whi…
