An alternative conception of PM10 concentration changes after short-term precipitation in urban environment
2018
Abstract In the article, a linear model is presented which describes a reduction of PM10 mass concentration in relation to the type of precipitation and water vapour content in the air. The model was built using covariance analysis. In studies of PM10 concentration changes, the results of 247 observations were used, which were carried out in the urban area. Concentration changes were archived during short-term (30 min) convection and large-scale rainfalls. For the determination of PM10 mass concentration, the reference method was used. To describe changes in PM10 concentration in the air after precipitation, a series of linear models were created, in which the explanatory variables were: th…
Outer suburbs, car dependence and residential choice in France, In: Planning After Petroleum: Preparing Cities for the Age Beyond Oil
2016
In a discussion of the findings of extensive research of everyday household practices, this chapter suggests effective policy responses to increasingly more expensive petrol prices. Our research involved interviews, observations and analyses of low-income households adapting their mobility practices and residential locations within highly car-dependent urban environments. The chapter examines two main types of practices of households in car-dependent outer suburbs: either households opt 'to stay', forgoing sustained mobility and a varied range of activities, or they choose 'to go' and relocate in areas where travel costs are less of a burden on their budgets. Our research analyzed statistic…
Acid sensitivity of neomycin-resistant mutants ofOenococcus oeni: a relationship between reduction of ATPase activity and lack of malolactic activity
1999
Mutants of Oenococcus oeni were isolated as spontaneous neomycin-resistant mutants. Three of these mutants harbored a significantly reduced ATPase activity that represented 50% of that of the wild-type strain. Their growth rates were also impaired at pH 5.3 (46-86% of the wild-type level). However, the profiles of sugar consumption appeared identical to those of the parental strain. At pH 3.2, all the mutant strains failed to grow and a drastic decrease in viability was observed after an acid shock. Surprisingly, all the isolated mutants were devoid of malolactic activity. These results suggest that the ATPase and malolactic activities of O. oeni are linked to each other and play a crucial …
AUGMENTED REALITY
2011
Already used in very specific areas such as in military and medical or academic research, in 2009 thanks to improved technology, augmented reality is to reach wider audiences and as information campaigns, advertising-augmented published in newspapers or on the network, and through a growing number of applications for mobile phones, particularly iPhone. "The Augmented Reality on the desktop computer is based on the use of markers, or ARtags, and stylized drawings, which are shown to the webcam, are recognized by the PC, and which are overlaid in real-time multimedia content: video, audio , 3D objects, etc.. Normally, applications of augmented reality are based on Adobe Flash technology and t…
La réussite en éducation musicale : des facteurs individuels aux facteurs contextuels
2007
This study aim to improve knowledge about individual and contextual factors of success in music education during elementary level's first year. There are three main subjects : acquisitions' social inequalities, teacher-effect and children' interest about in class musical activities. Two musical tests (one at the beginning of the year, another at the end) were administrated to 1184 students living in Burgondy. Questionnaries completed by various actors (teachers and students) gave a lot of data. Data were analysed with multivariate models. Our results demonstrated that 1°) musical practices develop abilities and explain social origin's effect on musical acquisitions at the beginning of the y…
Progetti di lessicografia onomastica dell’Atlante Linguistico della Sicilia
2022
L’Atlante Linguistico della Sicilia ha adottato, già una decina di anni fa, lo strumento del dizionario-atlante. Quando si è cominciato ad indagare il ricco universo onomastico, se ne è valutata la spendibilità anche su tre diversi corpora orali: uno relativo alle forme popolari del patrimonio toponomastico (DAToS, Dizionario-atlante toponomastico della Sicilia), uno riguardante l’inventario plurale dei soprannomi etnici (DASES, Dizionario-atlante dei soprannomi etnici in Sicilia), l’ultimo afferente al patrimonio antroponomastico popolare, individuale e familiare (DASS, Dizionario-atlante dei soprannomi di/in Sicilia). Il contributo fornisce lo stato dell’arte dei tre progetti e ne descriv…
Kant and Baumgarten on positing. Kant's notion of positing as a response to that of Baumgarten
2020
In the literature on Kant’s philosophy, it is almost universally ignored that Baumgarten used the notion of positing in a technical sense before Kant. In this article, I try to fill this gap in the literature by providing an analysis of Kant’s notion of positing in relation to Baumgarten’s one. I first show how Kant's differentiation of relative and absolute positing is not simply an alternative to Baumgarten's notion of existence, but is instead an alternative to his (usually ignored) notion of positing; I then develop a positive account of Kant’s notion of positing.
Civilidad y Buen gobierno: la "Policía" en el siglo XVIII
2008
El concepto y la práctica de la "policía" son una de las áreas más importantes desde finales del siglo XVII. Si estudiamos ese concepto y esa práctica podremos ver cómo las monarquías absolutas europeas desarrollan una nueva racionalidad de lo "político". De hecho, ambos términos fueron durante mucho tiempo sinónimos; ambos términos, la "policía" y la "política" en el siglo XVIII, tienen que ver con un ámbito de actuación global. Éste incluía lo material y lo espiritual, las cosas y los hombres, la producción y la ordenación de la riqueza, y también una nueva sociabilidad y una nueva "civilización". Era el arte del "buen gobierno". En este artículo repasamos los diversos modelos de desarrol…
Utilization of impedance spectroscopy to investigate the self-assembly behavior of amphiphiles soluble in supercritical carbon dioxide: Preliminary r…
2007
Abstract A mixture of CO 2 , water, methyl orange (MO) and Dynol 604 surfactant was analyzed at 309 K and 20 MPa simultaneously by impedance and UV–vis spectroscopy. A plot of the static dielectric constant as a function of the surfactant concentration was obtained using a suitable equivalent circuit to elaborate impedance data. Experimental points can be fitted by two different straight lines whose intersection occurs at about 0.13% (w/w) concentration of Dynol. When the surfactant concentration crossed the aforementioned value, a peak was detectable in the UV–vis spectrum at a wavelength range corresponding to the absorption of MO; absorbance of the peak increased with the surfactant conc…
Improving Dissolution Behavior and Oral Absorption of Drugs with pH-Dependent Solubility Using pH Modifiers: A Physiologically Realistic Mass Transpo…
2021
Orally dosed drugs must dissolve in the gastrointestinal (GI) tract before being absorbed through the epithelial cell membrane. In vivo drug dissolution depends on the GI tract's physiological conditions such as pH, residence time, luminal buffers, intestinal motility, and transit and drug properties under fed and fasting conditions (Paixao, P. et al. Mol. Pharm. 2018 and Bermejo, et al. M. Mol. Pharm. 2018). The dissolution of an ionizable drug may benefit from manipulating in vivo variables such as the environmental pH using pH-modifying agents incorporated into the dosage form. A successful example is the use of such agents for dissolution enhancement of BCS class IIb (high-permeability,…
