Archives and documents in the digital age

2017

Este artículo se propone reflexionar sobre algunas de las características del nuevo orden digital. En particular, se centra en las mutaciones que afectan a los conceptos de archivo y documento, así como a sus rasgos más destacados. Partiendo del hecho de que estos registros son fundamentales para cualquier estudioso del pasado, indaga sobre las consecuencias de su desmaterialización. Se examina el significado de ese espacio en algunas de sus dimensiones y se subraya la evidente paradoja que supone conservar y estudiar objetos o datos que son efímeros por naturaleza y que, en su mayoría, nacieron para morir rápidamente. The paper aims to examine and explore on some of the characteristics of …

La démocratisation de l'enseignement secondaire sous les deux septennats de François Mitterrand

2004

The democratization of the secondary education in France is a goal followed by the educational politics of the Education Ministers who followed one another during the François Mitterrand presidential area. But all these Ministers, in accordance to their own convictions and the different contexts they faced, have contributed to give this general politics a specific turn. This thesis aims at enlightening the various outlines that the democratization of the secondary education took during this period. It also questions the result of these successive politics.This study in politics history, trying to integrate a broad interdisciplinary field that gives different interpretation hypothesis of the…

Lack of association between celiac disease and dental enamel hypoplasia in a case-control study from an Italian central region

2007

Abstract Background A close correlation between celiac disease (CD) and oral lesions has been reported. The aim of this case-control study was to assess prevalence of enamel hypoplasia, recurrent aphthous stomatitis (RAS), dermatitis herpetiformis and atrophic glossitis in an Italian cohort of patients with CD. Methods Fifty patients with CD and fifty healthy subjects (age range: 3–25 years), matched for age, gender and geographical area, were evaluated by a single trained examiner. Diagnosis of oral diseases was based on typical medical history and clinical features. Histopathological analysis was performed when needed. Adequate univariate statistical analysis was performed. Results Enamel…

Effect of cobalt doping on the dielectric response of $B_{0.95}Pb_{0.05}TiO_3$ ceramics

2013

Dielectric response of Ba 0.95 Pb 0.05 TiO 3 ceramics doped with 0.1 and 1 wt.% of Co 2 O 3 , synthesized by conven- tional high-temperature method, wa s studied in wide temperature and frequency range. The temperature dependences of the real and the imaginary parts of dielectric permittivity of the ceramics were compared with those of BaTiO 3 and Ba 0.95 Pb 0.05 TiO 3. The addition of Co 3+ ions results in a broadening of dielectric anom- alies related to the transition to p araelectric cubic phase, and the structural transition between the tetragonal and the orthorhombic phases. At low temperatures (125 – 200 K) the dielectric absorp- tion of Co-doped Ba 0.95 Pb 0.05 TiO 3 ceramics was fo…

The contribution of geographical certification programs to farm income and rural economies: The case of Pecorino Siciliano PDO

2021

This study attempts to measure the capacity of the EU geographical certification scheme to positively influence the price of certified products and the incomes of their producers. A comparison of the economic results of two cheese-producing dairy farm enterprises with different business strategies and locations within the Sicilian hinterlands is performed in order to determine the transformation value of each dairy’s sheep milk into pecorino cheese (with and without the Protected Designation of Origin, or PDO, certification) and the related joint products (ricotta). The economic convenience of the total transformation of sheep milk into Pecorino Siciliano PDO and ricotta is also appraised. …

XML document-grammar comparison: related problems and applications

2011

10.2478/s13537-011-0005-1; International audience; XML document comparison is becoming an ever more popular research issue due to the increasingly abundant use of XML. Likewise, a growing interest fosters the development of XML grammar matching and comparison, due to the proliferation of heterogeneous XML data sources, particularly on the Web. Nonetheless, the process of comparing XML documents with XML grammars, i.e., XML document and grammar similarity evaluation, has not yet received the attention it deserves. In this paper, we provide an overview on existing research related to XML document/grammar comparison, presenting the background and discussing the various techniques related to th…

Chronic fluoxetine treatment in middle-aged rats induces changes in the expression of plasticity-related molecules and in neurogenesis

2012

Abstract Background Antidepressants promote neuronal structural plasticity in young-adult rodents, but little is known of their effects on older animals. The polysialylated form of the neural cell adhesion molecule (PSA-NCAM) may mediate these structural changes through its anti-adhesive properties. PSA-NCAM is expressed in immature neurons and in a subpopulation of mature interneurons and its expression is modulated by antidepressants in the telencephalon of young-adult rodents. Results We have analyzed the effects of 14 days of fluoxetine treatment on the density of puncta expressing PSA-NCAM and different presynaptic markers in the medial prefrontal cortex, hippocampus and amygdala of mi…

Study of postural control and body balance in subjects with Down syndrome

2020

Purpose. Body imbalance and poor postural control have negative impact on gait and may increase the risk of falling in healthy individuals as well as those with Down syndrome (DS). Since people with DS have lower physical levels than people who do not present this condition, the purpose of our research was to compare features of postural control and body balance between subjects affected by DS and a control sample. Methods. Participants enrolled were divided into the following two groups: A DS group (DSG; n = 22; 9 females and 13 males; age range: 16-36 years) and an age-matched control group (CG; n = 25; 11 females and 14 males; age range: 16-36 years). All participants were subjected to t…

Impact of Noah-LSM Parameterizations on WRF Mesoscale Simulations: Case Study of Prevailing Summer Atmospheric Conditions over a Typical Semi-Arid Re…

2021

The current study evaluates the ability of the Weather Research and Forecasting Model (WRF) to forecast surface energy fluxes over a region in Eastern Spain. Focusing on the sensitivity of the model to Land Surface Model (LSM) parameterizations, we compare the simulations provided by the original Noah LSM and the Noah LSM with multiple physics options (Noah-MP). Furthermore, we assess the WRF sensitivity to different Noah-MP physics schemes, namely the calculation of canopy stomatal resistance (OPT_CRS), the soil moisture factor for stomatal resistance (OPT_BTR), and the surface layer drag coefficient (OPT_SFC). It has been found that these physics options strongly affect the energy partiti…
