Synthesis of Hybrid Tripeptide Peptidomimetics Containing Dehydroamino Acid and Aminophosphonic Acid in the Chain and Evaluation of Their Activity to…
2021
Synthesis of a new group of hybrid phosphonodehydropeptides composed of glycyl-(Z)-dehydrophenylalanine and structurally variable aminophosphonates alongside with investigations of their activity towards cathepsin C are presented. Obtained results suggest that the introduction of (Z)- dehydrophenylalanine residue into the short phosphonopeptide chain does induce the ordered conformation. Investigated peptides appeared to act as weak or moderate inhibitors of cathepsin C.
Applications of Quantum Chemistry in Spectroscopy: Molecules, Complexes of Van der Waals, trapped Molecules
2009
I described in this memory my activities as a researcher at Tomsk well before 2003, in succession to the State University of Tomsk in the Faculty of Physics, Institute of Physics of Siberia, and the Institute of 'Atmospheric Optics, in France since then, mostly at the University of Bourgogne (ICB), but also at the University of Lille I (PhLAM) and the University of Marne-la-Vallée (LCT). Part of my work has been dedicated to the evaluation by calculating ab initio of rovibrational constants for quasi-spherical molecules. The centrifugal distortion constants and the dipole moment of the molecule SO2F2 were calculated to validate the tensor theory and interpreter the spectrum. I twas shown th…
Initial validation of the Psychobiosocial States in Physical Education (PBS-SPE) scale
2018
The purpose of this cross-sectional investigation was to examine the item characteristics, factor structure, reliability, convergent validity, and nomological validity of the Psychobiosocial States in Physical Education (PBS-SPE) scale. In Study 1, a sample of 1,030 students (582 girls and 448 boys, 10 to 19-year-olds), drawn from middle or high schools, rated the intensity of the 20 items version of the PBS-SPE scale thinking about the feelings they had usually experienced in physical education classes. In Study 2, an additional sample of 1,025 students (578 girls, 447 boys, 10 to 19-year-olds), rated the 16 items of the final version of the scale. Two subsamples also completed an affectiv…
Evaluating the Efficiency of Different Regression, Decision Tree, and Bayesian Machine Learning Algorithms in Spatial Piping Erosion Susceptibility U…
2020
Piping erosion is one form of water erosion that leads to significant changes in the landscape and environmental degradation. In the present study, we evaluated piping erosion modeling in the Zarandieh watershed of Markazi province in Iran based on random forest (RF), support vector machine (SVM), and Bayesian generalized linear models (Bayesian GLM) machine learning algorithms. For this goal, due to the importance of various geo-environmental and soil properties in the evolution and creation of piping erosion, 18 variables were considered for modeling the piping erosion susceptibility in the Zarandieh watershed. A total of 152 points of piping erosion were recognized in the study area that…
Toward Quaternary QCA : Novel Majority and XOR Fuzzy Gates
2022
As an emerging nanotechnology, quantum-dot cellular automata (QCA) has been considered an alternative to CMOS technology that suffers from problems such as leakage current. Moreover, QCA is suitable for multi-valued logic due to the simplicity of implementing fuzzy logic in a way much easier than CMOS technology. In this paper, a quaternary cell is proposed with two isolated layers because of requiring three particles to design this quaternary cell. Moreover, due to the instability of the basic gates, the three particles cannot be placed in one layer. The first layer of the proposed two-layer cell includes a ternary cell and the second one includes a binary cell. It is assumed that the over…
Attitudes and related perceptions about product placement: a comparison of Finland, Italy and the United States
2015
The primary goal of our study is to explore cross-national differences in attitudes and perceptions about product placements, after investigating measurement invariance. Our cross-national focus includes three countries that have not been compared previously: Finland, Italy and the USA, which differ significantly in terms of the evolution/maturity of product placement markets, regulatory structures and cultural contexts. Motivated by earlier studies, we investigate the cross-national measurement invariance of scales to measure four research constructs related to the product placement domain (attitude toward credibility of advertising, attitude toward advertising-in-general, attitude toward …
Impact of Emotional Intelligence on Burnout among Spanish Teachers: A Mediation Study
2021
espanolLa utilidad de la inteligencia emocional y su efecto tranquilizador sobre el estres laboral de los profesores han ido cobrando importancia en este campo de investigacion. El objetivo de este estudio ha sido analizar la relacion entre las habilidades emocionales y el sindrome de burnout y si el equilibrio afectivo media esta asociacion. Se han utilizado modelos de ecuaciones estructurales con datos de autoinforme de 200 profesores cuya edad estaba comprendida entre los 22 y los 64 anos (M = 44.97, SD = 9.31, 73.50% mujeres). Se utilizo un diseno transversal para el estudio. Los resultados mostraron un efecto significativo directo e indirecto de la claridad y de la reparacion emocional…
Parental Affection and Psychological Control as Mediators Between Parents’ Depressive Symptoms and Child Distress
2013
The present study investigated the extent to which parental behavior in daily interaction with one’s child mediates the associations between parental depressive symptoms and children’s daily distress. The participants were 152 Finnish families with a 6- to 7-year-old child. Parents’ depressive symptoms were assessed using the revised Beck Depression Inventory. Children’s distress was operationalized as negative daily emotions assessed by using mother-, father-, and teacher-reported diary questionnaires. Parental affection and psychological control in daily interaction were measured using parent self-reported diary questionnaires. The results of structural equation modeling showed that both…
The Fear of Covid-19 Scale (FCV-19S) in Spain: Adaptation and Confirmatory Evidence of Construct and Concurrent Validity
2021
Fear of the coronavirus has important implications on mental health. In western countries, a significant degree of vaccination has been achieved, but in Spain, less than 75% of the population has received both doses. The current situation is still seen as a threat by many people. Therefore, it is important to have reliable and valid measurement instruments to assess the impact of COVID-19 on the population. In this study, the Fear of COVID-19 Scale has been adapted to Spain, and its psychometric properties have been studied in a Spanish sample using Structural Equation Modeling. This methodology allows obtaining more reliable estimates, regardless of the measurement scale of the variables. …
Psychometric Evaluation of the Norwegian Versions of the Modified Group Environment Questionnaire and the Youth Sport Environment Questionnaire
2021
This study aimed to translate the modified Group Environment Questionnaire (GEQ) and the Youth Sport Environment Questionnaire (YSEQ) into Norwegian, examine the factor structure and reliability of the scales through independent clusters model confirmatory factor analysis (ICM-CFA) and exploratory structural equation modeling (ESEM), and examine differential item functioning (DIF) as a function of sex. Three-hundred-and-thirty-three athletes (M(SD)age = 18.7(2.60) years; 33% females) completed the GEQ. Three-hundred-and-three athletes (M(SD)age = 15.0(1.48) years; 26% females) completed the YSEQ. Results indicated acceptable fit indices for a four-factor, a second-order two-factor (task a…
