Improved embedded molecular cluster model

2002

We demonstrate that boundary effects (i.e., displacements of the cluster boundary atoms from their lattice sites and the difference between effective charges of the perfect crystal atoms and those of the cluster atoms in the case of a cluster with no point defect in it) in an embedded molecular cluster (EMC) model can be radically reduced. A new embedding scheme is proposed. It includes search for the structural elements (SE) of which perfect crystal is composed, use of corresponding to these SE expression for the total energy, and application of the degree of localization of equations consistent with the wave functions of the cluster. To get equations for the cluster wave functions, the pr…

Interaction effects of enniatin B, deoxinivalenol and alternariol in Caco-2 cells.

2015

Enniatin B (ENN B), deoxinivalenol (DON) and alternariol (AOH) are secondary metabolites of filamentous fungi. These mycotoxins are contaminants of vegetables and cereals. They are cytotoxic and their effects are enhanced by their mixtures. The objectives of this study were to compare the cytotoxicity of ENN B, DON and AOH alone or in combination in human adenocarcinoma (Caco-2) cells and to evaluate the type of interactions of mycotoxin mixtures by the isobologram analysis. Cells were treated with concentrations ranging from 1.85 to 90μM (AOH) and from 0.312 to 10μM (for ENN B and DON), individually and in combination of two and three mycotoxins (from 1.85 to 30μM for AOH and from 0.312 to…

A comparative study between Chinese and Finns : communication accommodation and values exchange in grandparent and grandchild communication

2017

This study explores differences and similarities between grandparent-grandchild (GP-GC) communication in China and Finland. GP-GC communication and relationship has been understudied for decades since scholars in family communication domain have been focusing on relationships among other family members. The culture of the residents of China, the origin of Confucianism, is isolated from that of other East Asian nations. In view of dramatic socioeconomic development, examining how the traditional GP-GC relationship within the family has changed is valuable. On the other hand, Finland possesses a culture with contrasting traits. Characterized by individualism, Finns are prone to focus primaril…

Tobacco plants detect a decrease of environmental genotoxicity in Toulouse (France).

2003

Tobacco plants, heterozygous for two independent loci involved in the chlorophyll parenchyma differentiation, allow the genotoxic effects of the atmosphere of the industrial estate South of Toulouse to be estimated. Somatic spots of green cellular colonies on yellow-green background, were counted to calculate the cellular rates of reversion. Two experiments were carried out in 1981, and in 1997. A general decrease of genotoxic effects was observed. These observations were interpreted as being due to a general decrease of the air pollution evaluated by the development of the concentrations of three toxic gases before and after the implementation of cleanup devices. The results obtained demon…

Efficient Production of Isoflavonoids by Astragalus membranaceus Hairy Root Cultures and Evaluation of Antioxidant Activities of Extracts

2014

In this study, Astragalus membranaceus hairy root cultures (AMHRCs) were established as an attractive alternative source for the efficient production of isoflavonoids (IF). A. membranaceus hairy root line II was screened as the most efficient line and was confirmed by PCR amplification of rolB, rolC and aux1 genes. Culture parameters of AMHRCs were systematically optimized, and five main IF constituents were quali-quantitatively determined by LC-MS/MS. Under optimal conditions, the total IF accumulation of 34 day old AMHRCs was 234.77 μg/g dry weight (DW). This yield was significantly higher compared to that of 3 year old field grown roots (187.38 μg/g DW). Additionally, in vitro antioxidan…

Musical pitch quantization as an eigenvalue problem

2020

How can discrete pitches and chords emerge from the continuum of sound? Using a quantum cognition model of tonal music, we prove that the associated Schrödinger equation in Fourier space is invariant under continuous pitch transpositions. However, this symmetry is broken in the case of transpositions of chords, entailing a discrete cyclic group as transposition symmetry. Our research relates quantum mechanics with music and is consistent with music theory and seminal insights by Hermann von Helmholtz.

Conversion as Negotiation. Converts as Actors of Civil Society

2020

This article focuses on the religious movement of the Ahmadiyya and its civil society organization, Humanity First, in West-Africa and in Europe. Particular attention is paid to the place of converts within these two institutions. Conversions to an Islamic minority and the actions of this minority are studied through the prism of social commitment. I examine the intersections between religious values, the ideas of solidarity in the societies under scrutiny and, the kaleidoscopic range of Muslim charities. The paper investigates conversion as negotiation in regard to gender, social mobility, and power. Conversion is approached here as a matter of social relations and not personal belief. I a…

Culture-Civilization-Organizational Culture and Managerial Performance

2015

Abstract The paper aims at unfolding the organizational culture as a background idea, with genuine connections it has with the concept of culture and civilization, inseparable and complementary concepts in modernizing organizational culture and in the more successful integration within the EU.

Romanian Folk Literature in Our Classes: A Proposal for the Development of Intercultural Competence

2015

Abstract The present research highlights the ways in which folk literature, this valuable tool that contributes to students’ formation from both a human and literary perspective, can promote intercultural competence in class and foster a better integration within the community, while consolidating favorable attitudes towards interculturality. We share Rodriguez Almodovar's view (2009), according to which the folk story makes the geographic space expand; it channels affectivity, while guiding the learning process towards the acceptance of social values that are representative for each culture. The objectives of our study are focused, on the one hand, on improving intercultural competence amo…
