Capillary electrophoresis enhanced by automatic two-way background correction using cubic smoothing splines and multivariate data analysis applied to…
2005
Mixtures of the surfactant classes coconut diethanolamide, cocamido propyl betaine and alkylbenzene sulfonate were separated by capillary electrophoresis in several media containing organic solvents and anionic solvophobic agents. Good resolution between both the surfactant classes and the homologues within the classes was achieved in a BGE containing 80 mM borate buffer of pH 8.5, 20% n-propanol and 40 mM sodium deoxycholate. Full resolution, assistance in peak assignment to the classes (including the recognition of solutes not belonging to the classes), and improvement of the signal-to-noise ratio was achieved by multivariate data analysis of the time-wavelength electropherograms. Cubic s…
Positive Psychological Capital as a Predictor of Satisfaction With the Fly-In Fly-Out Model
2021
The flexibility of the markets and international agreements lure a growing number of companies to expand their business beyond frontiers in search for new markets and a bigger business network. Workers, initially called expatriates, become keystones to implant and promote the so desired expansion into the international markets. From the concept of flexpatriate present in the literature in general, we adapted the concept of FLY-in FLY-out (FIFO) to comprehend the organizational flexpatriates. In the midst of the Positive Psychology theories, Luthans et al. underline that workers are the psychological capital of the companies. Therefore, the development of the Positive Psychological Capital b…
Microvascular periodontal alterations: A possible relationship between periodontitis and rheumatoid arthritis.
2007
Abstract BACKGROUND: Microvascular involvements represent one of the first steps in many autoimmune diseases such as rheumatoid arthritis (RA). The aim of this study was to investigate the differences in periodontal microcirculation between healthy subjects and patients suffering from RA. METHODS: Thirty healthy subjects and 30 patients suffering from RA were examined. The patients who showed conditions known to compromise microcirculation, such as diabetes, hypertension, pharmacological treatments, were not included in the group of healthy patients. All the patients were non-smokers. Periodontal capillaroscopy was used to investigate the characteristics of microcirculation. Visibility, cou…
Le rôle du marché des dirigeants dans le système de gouvernance des entreprises : une revue de la littérature
2005
National audience; L'objectif de cet article est, en s'appuyant sur la littérature existante, d'appréhender et de comprendre le rôle d'un mécanisme particulier:le marché des dirigeants, à l'intérieur du système de gouvernance des entreprises. La grille de lecture utilisée est synthétique, permettant d'étudier les voies d'intervention potentielles du marché managérial aussi bien sous la dimension disciplinaire que cognitive. L'apport principal de cet article est d'aboutir à une vision globale et complète du rôle de ce mécanisme, venant remettre en cause la perception généralement négative du marché des dirigeants, considéré inefficient, de type clanique, notamment en France. Cette revue cons…

The creation of a country’s wealth and dynamism depends upon the competitiveness of its firms and this, in turn, relies fundamentally on the capabilities of its entrepreneurs and managers.
The Role of Intraindustry Trade in Interregional Trade in the Midwest of the US
2007
The subject of international trade among countries has long been of concern to policy makers and academics alike. As economic activity has become more and more international in scope, the potential impact of international trade on regional economic growth and income distribution has become central to many studies. Within economics, the study of industrial organization, particularly with respect to imperfect competition and economies of scale and agglomeration, has influenced developments in international trade theory in the past few decades. In identifying the determinants of trade among countries, issues such as market size, relative level of Gross National Product (GNP) per capita, market…
Analytical methods to determine cocaine contamination of banknotes from around the world
2008
Abstract The presence of cocaine in a significant number of UK pounds (Xxxx), Euros (€) and North American banknotes ($) in general circulation requires appropriate tools to do determinations. This article discusses the-state-of-the-art in the analysis of cocaine on banknotes. We summarize the usual extraction methods of currency samples and compare them, especially with respect to avoiding sample damage. We critically discuss analytical methods, namely gas chromatography (GC) and liquid chromatography (LC), capillary electrophoresis (CE), immunoassay, thermal desorption tandem mass spectrometry (TD-MS2) and ion-mobility spectrometry (IMS). We also review cocaine levels on banknotes around …
Capillary zone electrophoresis for the determination of thiabendazole, prochloraz and procymidone in grapes
2001
Capillary zone electrophoresis with UV detection was applied to the simultaneous determination of thiabendazole, prochloraz and procymidone in grapes. Electrolyte conditions such as pH, composition and concentration of the buffer, addition of organic solvent and working voltage were checked to obtain a high-performance separation of the three fungicides (by measurement of separation efficiency and resolution). The most critical parameter was the pH of the running buffer. The best separation was achieved in 4 mM phosphate solution at pH 3.5. The repeatability of the migration times, expressed as RSD, was <0.44%. The three peaks were completely resolved with a separation efficiency up to 100 …
A Psychiatrist Caught in a Civil War: Rodríguez Lafora's Work in Valencia, Capital of The Republic (1936-1938)
2018
espanolUn periodo poco conocido de la vida de Rodriguez Lafora es el que paso en Valencia durante la guerra civil espanola, desde 1936 hasta su exilio en 1938. Durante la guerra, Valencia se convirtio en capital de la republica y muchos cientificos e intelectuales encontraron alli un refugio donde tratar de continuar su labor. Lafora participo, junto a otros intelectuales evacuados, en numerosas actividades cientificas y academicas organizadas desde la Casa de la Cultura de Valencia, donde llego a mantener una controversia con Antonio Machado y otros intelectuales a raiz de la disolucion de la misma. Destacamos especialmente su trabajo como medico psiquiatra en el Hospital Militar de Sangre…
