Semiconductor mixed oxides as innovative materials for the photocatalytic removal of organic pollutants
2020
Abstract This work aims to provide a critical survey of the extensive literature concerning the potential applications of nanostructured mixed oxides for environmental remediation. In particular, our attention was focused on the feasibility to employ these materials as photocatalysts for the elimination of toxic organic pollutants contained in water and wastewater. The advantages and perspectives of the various nanocomposites are briefly discussed.
Pharmacological and chemical features ofNepetaL. genus: Its importance as a therapeutic agent
2017
Medicinal plants have always had great value for the human population due to their valuable constituents and potential bioactivities. The objective of this review is to present an updated overview of an important medicinal plant genus Nepeta L., from the family Lamiaceae, revealing its traditional utilization, biological activity, phytoconstituents, and mechanisms of action. For this purpose, a literature survey was carried out by using SciFinder, ScienceDirect, Scopus, PubMed, and Web of Science followed by a revision of the bibliographies of the related articles. We have described and analyzed the role of plants in drug discovery and the importance of Nepeta species. Information on the ut…
Management and Outcome of Mucosal Injury During Pyloromyotomy--An Analytical Survey Study.
2015
Different approaches of dealing with mucosal injury during pyloromyotomy for hypertrophic pyloric stenosis have been described. There is, however, no consensus on the best technique to use. We conducted a survey among International Pediatric Endosurgery Group (IPEG) members on their experience of mucosal injuries during pyloromyotomy, the way in which these were handled, any modification in subsequent postoperative care, and impact on outcome.A confidential survey was sent to IPEG members querying demographic data, number of pyloromyotomies performed, operative approach, incidence of mucosal injury, intraoperative management, and postoperative consequences. Statistical analysis was performe…
The analysis of poverty in Italy. A fuzzy dynamic approach
2004
The commonly used criterion to sharply separate the poor from the non poor on the basis of a poverty threshold appears to be too severe in comparison with the nature of poverty. The latter is multidimensional in its components (domain) and continue in its states (codomain). Moreover an income-based poverty line allows for a remarkable number of spurious transitions below and over that line, which do not correspond to true variations in household’s standard of living. This study starts from the analysis of common (with crisp states) transition matrices; then a fuzzy multidimensional poverty indicator is built. In conclusion, fuzzy states transition matrices synthesize interpretative content …
Modern health worries and idiopathic environmental intolerance.
2008
Abstract Objective We conducted two studies to test whether modern health worries (MHWs) were associated with central features of a condition called idiopathic environmental intolerance (IEI) and medical care utilization. Methods In Study 1, 474 Internet users completed an Internet-based questionnaire that assessed MHWs, IEI features, and medical care utilization. In Study 2, the diagnostic specificity of MHWs was investigated by comparing the level of MHWs of three diagnostic groups: 46 people with IEI, 38 people with somatoform disorder but without IEI, and 46 people with neither IEI nor somatoform disorder. Results The good psychometric properties of the MHW scale were confirmed. MHWs we…
Magnetic imaging of a late Bronze Age tumulus in France before and during excavation
2002
Geophysical surveying is taking place in the Chatillon-sur-Seine area in France to examine and map prehistoric settlements and the structure of tumuli (grave-mounds which originally reached a height of up to 5 m but which are now almost level). The magnetic survey discussed here was conducted to detect archaeological structures within a late La Tene (100-50 bce) necropolis, in particular the preexcavation recording of a late Bronze Age round barrow. During the excavation, additional surveys were carried out to analyze the influence of immediate subsurface soil layers on the magnetic anomalies originating from the deeper archaeological features. Additional radar surveys made use of a 500 MHz…
Consommation alimentaire des nourrissons et des enfants en bas âge en France en 1997
1999
Resume En 1981 et 1989, deux enquetes nationales decrivaient l'evolution de la consommation alimentaire des nourrissons francais. En 1997, une troisieme enquete a ete realisee par les memes equipes suivant la meme methode. Population et methodes L'echantillon, representatif, est constitue de 660 enfants de 1 a 30 mois. La quantite de chaque aliment ingere par chaque enfant a ete relevee pendant 3 jours. On a calcule la valeur energetique de la ration, l'apport en protides, lipides, glucides, mineraux, vitamines et acide linoleique, la repartition des apports entre les repas de la journee et le pourcentage de l'energie provenant des differents aliments. Resultats De 1989 a 1997, la part des …
Evolution et structure des compétences des élèves à l'école élémentaire et au collège : une analyse empirique des évaluations nationales
2006
Il s'agit de la synthèse du rapport final en réponse à l'appel d'offres : Maîtrise du langage, diversité des pratiques pédagogiques et socle commun de compétences, pour le Centre Henri Aigueperse, UNSA-Education. La recherche, basée en grande partie sur l'analyse des résultats des élèves aux évaluations nationales, a pour objectif principal de mieux comprendre comment les acquisitions scolaires se structurent dans une double perspective : transversale (à un moment donné de la scolarité) et longitudinale (au cours des cycles d'enseignement). Dans cette optique, des données ont été collectées sur un échantillon d'environ 700 élèves originaires d'une même circonscription scolaire à différents …
Trends and cycles in U.S. job mobility
2021
Recent studies document a decline in U.S. labor-market fluidity from as early as the 1970s on. Making use of the Annual Social and Economic (ASEC) supplement to the Current Population Survey (CPS), I uncover a pronounced increase in job-to-job mobility from the 1970s to the 1990s, i.e., the annual share of continuously employed job-to-job movers rises from 5.9 percent of the labor force in 1975–1979 to 8.8 percent in 1995–1999. Job-to-job mobility exhibits a downward trend only since the turn of the millennium. In order to provide a formal economic interpretation, I additionally estimate the parameters of the random on-the-job search model. Furthermore, I document that job-to-job mobility h…
Integrating Virtual Realities and Psychotherapy: SWOT Analysis on VR and MR Based Treatments of Anxiety and Stress-related Disorders
2021
© 2021 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group.The use of virtual reality (VR) and mixed reality (MR) technology in clinical psychology is growing. Efficacious VR-based treatments for a variety of disorders have been developed. However, the field of technology-assisted psychotherapy is constantly changing with the advancement in technology. Factors such as interdisciplinary collaboration, consumer familiarity and adoption of VR products, and progress in clinical science all need to be taken into consideration when integrating virtual technologies into psychotherapies. We aim to present an overview of current expert opinions on the use of virtual…
