In this article, I try to shed light on the (Fregean) project of a logic of arithmetic—as discussed by Natorp and Rickert—by outlining three main ques- tions. Is the number a logical object? Is arithmetic reducible to logic? Is it possible to deduce the arithmetical operations from purely logical laws? I argue that rigorous distinction between these three questions makes it possible to elucidate many prob- lems affecting the program of a logic of arithmetic. The Neo-Kantian contribution to this program is at the same time considered in a new light. [less ▲]

This work addresses the responses of the Atlas Mountain Cedar tree (Cedrus atlantica Manetti) when faced with past and future climactic changes. The ecological study of this species proposes three simulations based on reliable and precise data: - Simulation in 6000 B.P. with the GCM UBRIS-HadCM3M2 climatic data - Simulation in the year 2000 with NEW et al. climactic data (2002) - Simulation in the year 2100 with the ARPEGE Climactic Model data - following the IPCC's scenario A2 These simulations were realized using the CARAIB model, which simulates Carbon stocks in vegetation and Carbon flux between vegetation, soil and atmosphere. In part one, the Moroccan Atlas Mountains, which constitute the principal natural area of the Atlas Cedar tree are described in detail. The different data describing this species' distribution at three periods are summarized: 1) at the present time, 2) at Holocene period and 3) at the end of the Upper Pleniglacial period . The distribution of the species is specified. A map of the Cedar tree's actual distribution in Morocco was drawn from a series of population maps - scale 1/25,000- kept at the Moroccan Ministry of Forestry and Water conservation. So as to improve the sequential study of fossils of Cedar pollen was defined the percentage threshold at which samples containing pollen from the Cedrus atlantica are described as autochtonous or allochthonous. The study of 514 samples of Moroccan Cedar pollen permittted to define this threshold as 1% with minimal risk of error. The last part of the work is focused on modelling. It starts with a description of IBM and CARAIB models used in the three simulations. The data essential for these models are reviewed. Considering the climactic data for these three periods, climate is globally warmer in 6000 BP and in 2100 than today, with the problems of drought becoming more severe in the future. The analysis of the three simulations brings us to two conclusions. Cedrus antlantica is sensitive to climactic change and shows that, at three different periods, its potential distribution areas are quite different. At 6000 BP, the species sought refuge in the high mountains of North Africa. Today's distribution is well simulated in our model. Its good survival in Europe makes it an interesting species for reforestation. In 2100, if IPCC's A2 scenario is validated, modifications in the Cedar's potential and real area of distribution will be considerable. The tree will find little refuge in North Africa. On the other hand, the climate of the land between the Northern Alps and the South of Sweden, associated with a strong concentration of CO2 in the atmosphere may well provide it with an acceptable environment.

L’ozone (O3) est présent dans l’atmosphère terrestre en quantité limitée, avec un maximum de concentration entre 15 et 50 km d’altitude. Cette molécule y joue un rôle essentiel en filtrant les rayons solaires ultraviolets dont les effets sur les êtres vivants peuvent être nocifs. L’influence des activités humaines sur la couche d’ozone stratosphérique s’est manifestée dès le début des années 1980, principalement au dessus de l’Antarctique, où une baisse significative de la quantité totale d’ozone a été observée chaque printemps (ce que l’on nomme communément le «trou dans la couche d’ozone»). Depuis la mise en oeuvre du Protocole de Montréal en 1987, les émissions mondiales de substances halogénées à l’origine de cette destruction ont fortement diminué, laissant présager, sous nos latitudes, un retour à la normale de l’épaisseur de la couche d’ozone vers 2050.

In this work, an empirical correlation is proposed to describe kLa as a function of operating conditions (agitation and aeration rates) and of oil and surfactant volumetric fractions in a biotransformation medium, an oil-in-water dispersion. An interaction effect between the oil and the surfactant effects was found, since oil presence increased kLa in the absence of the surfactant but had an opposite effect when Tween 80 was available in the medium. The biotransformation of methyl ricinoleate (MR) into γ-decalactone (an aroma compound of industrial interest), by the yeast Yarrowia lipolytica, was carried out at different conditions of operation, to evaluate the influence of kLa on the production of the aroma. It was demonstrated that kLa had an influence on the aroma production; however, for the low hydrophobic substrate concentration used (1.08% v/v) and cellular density of 2.0 × 107 cells mL-1, a minimal kLa value of 70 h-1 was necessary to attain the maximal aroma production. © 2007 Elsevier B.V.

The main contribution of this paper is the construction of a strong duality for the varieties generated by a set of subalgebras of a semi-primal algebra. We also obtain an axiomatization of the objects of the dual category and develop some algebraic consequences (description of the dual of the finite structures and algebras, construction of finitely generated free algebras,. . . ). Eventually, we illustrate this work for the finitely generated varieties of MV-algebras. [less ▲]

Didelphys uterus with imperforated obstructed hemivagina is a rare condition. Most often, it is diagnosed a few months after the menarche. Hematocolpos, hematometria and sometimes hematosalpinx are responsible for pelvic pain and dysmenorrhea. Symptoms can be delayed when a fistulisation from the hematocolpos to permeable contralateral vagina is present. Sometimes, diagnosis is not made before adulthood during an infection of the hematocolpos. Useful additional exams include pelvic ultrasound and, in some cases, MRI, which is the best exam to precisely describe the type of malformation. An ipsilateral agenesia of the kidney is always associated. Hysterography can usually demonstrate the fistulous courses. Treatment consists in a large resection of the vaginal septum in order to allow a permanent drainage of the hemiuterus. A laparoscopy should be performed to check for the presence of associated tubal or pelvic damage. [less ▲]
