Abdominal Computed Tomography Angiography at 80kV: feasibility study.
2014
preliminary evaluation of different dose reduction algorithms in abdominal Computed Tomography Angiography (CTA) with standard scan protocols at 120kV vs. 80kV.prospective, randomized, crossover study. 60 consecutive patients who underwent CTA of the abdomen (Sensation 64, Siemens; Iomeprol 400 mgl/ml Bracco) for suspected or diagnosed Abdominal Aortic Aneurysm (AAA) were enrolled in the study. A standard 120kV/200mAs scan protocol was acquired in all patients (reference tube current modulated with Automatic Exposure Control). In each patient a second scan with 80kV/300mAs (Group 1; n. 20), 80kV/400mAs (Group 2; n. 20), 80kV/500mAs (Group 3; n. 20) was acquired. We used the same scan/recons…
The tools like evidences of metal working? : strike supports, abrasives and burnishers, sharpening tools and crushing tools
2013
Lots of lithic tools are present in Metal Ages, but few are studied. In metal production, they are especially constitued by strike supports, abrasives, burnishers, sharpening tools and crushing tools. A part of them are in metal ( strike supports) or in ceramic (abrasives, sharpening tools). Contemporary forms of these tools are too different to permit a dierct comparison. It is necessary to work on the function of the tools, deduced from the analysis of these structure. Strike supports used for metal working are easily identifiable. They allow to reproduce more or less precisely the objects that they were fabricated with. Abrasives are difficult to relate to a material, but the traces of u…
L'utilisation de la musique comme support de nouveaux apprentissages dans le vieillisement normal et la maladie d'Alzheimer
2012
This thesis research aims to test the potential of music as a mnemonic support for new learning in normal elderly and Alzheimer’s disease (AD) participants. Several studies have highlighted the beneficial effects of music on cognition in aging and dementia. At the same time, in young adults, the idea that music could serve as a mnemonic support is highly debated. Yet, very few studies addressed this question in aging or dementia. In the present work, we conduct two studies in a cohort of 8 mild Alzheimer’s disease and 7 matched control participants. The first study concerns verbal memory, and compares learning and different retention delays of lyrics (unknown texts) that are either spoken o…
The implicit motor learning use as a therapeutic tool in frail elderly people
2016
To write, take, walk, talk is a part of our daily. Our motor ability is used to change depending on our environment and our skill, acquired thanks to our experience, learnings, and according to our age. We strive to find optimal solutions, to be more performants, more efficient. But we must be able to discern to act well and act to better discern. This « perception-action » coupling is the basis of the organization of motor control. Human can discern through several sensory systems (Visual, auditory, proprioceptive) intrinsic informations, coming from his own body, and extrinsic informations, from his environment. All of these informations are in the service of the movement and actions of d…
Paysage et médiatisation dans les Alpes françaises - Approche géographique de la diffusion des cartes postales paysagères
2010
The usual little holiday ritual, landscape postcards have for first purpose to maintain the social link between people going on holiday and people staying at home. But, by giving a view of a certain area from a different place, those postcards represent an original manner to apprehend touristic places and to answer a seemingly simple question: Why this landscape would be sold on that particular spot ? This theoretical question leads to other questions: Is there a hierarchy among those touristic sites? Would the lack of attractivity of several territories cause their eviction? Would the media coverage of sites have effects upon the destruction of territories ? To answer all those questions, …
The mental lexicon in french foreign language vocabulary teaching and learning : the case of the acquisition of the past perfect by Colombian L3 fren…
2016
This research presents the force that manifests the mental lexicon in teaching vocabulary in French as a foreign language. This experimental action research was developed with the experimental French group II EG from the program of modern languages at the University of Quindio in Armenia City, in Colombia. Students presented a low level in oral and written French activities. The lack of vocabulary was a recurrent element in the expression of the language. The purpose of this research is therefore focused on improving vocabulary acquisition in French through a series of learning sessions of the French’s present perfect taking into account the three pillars of the knowledge of words expressin…
L’apport de la modélisation par équations structurelles en SHS
2022
La recherche tente d’expliquer l’appropriation de la formation initiale des sapeurs-pompiers volontaires, à partir de différents facteurs internes et externes à l’apprenant : d’une part le rapport au savoir de l’individu, le sens qu’il attribue à la formation et sa motivation dans l’activité formative et d’autre part sa perception des formateurs, des groupes d’apprenants et de l’évaluation.Pour comprendre la manière dont chacun de ces facteurs intervient dans le processus d’appropriation, il paraît nécessaire d’estimer le poids exercé par chacun d’eux dans un raisonnement dit toutes choses égales par ailleurs. Pour ce faire une analyse en structures de covariances est mobilisée. Cette métho…

Spectrophotometric determination of promazine with an oxidative column in FIA manifolds
1992
Abstract A simple flow-injection spectrophotometric method for the determination of promazine is described. The two proposed procedures are based on the oxidation of analyte with a manganese dioxide column. Concentrations of promazine in the ranges 2–20 and 1–6 are determined with a relative standard deviation of 1.0%. The injection rates are 62 and 80 samples h −1 , respectively. The influence of foreign species and the determination of promazine in a pharmaceutical formulation are also reported.
Determination of tannic acid by direct chemiluminescence in a FIA assembly
2002
The determination of tannic acid is performed in a FIA assembly on the basis of the analytical output obtained by oxidation of the acid. The analyte solution was daily prepared in a mixture of quinine as sensitiser and perchloric acid and it was injected into a pure water stream acting as a carrier. This solution merges with the mixture potassium permanganate in perchloric medium and the resulting chemiluminescence is monitored. The method was applied over the range 0.5-20 mg l(-1) of tannic acid with a LOD 100 mug l(-1). The reproducibility was 2.1% and the sample throughput 54 h(-1). The influence of foreign substances was studied and the new method is applied to the determination of tann…
