Les quatre vieilles colonies : la dialectique de l'assimilation et du principe de la départementalisation chez Victor Schoelche

1999

International audience; Victor Schoelcher est surtout connu en tant qu'abolitionniste de l'esclavage et malheureusement moins pour ses autres combats. Il désirait participer à la fondation d'une République, démocratique, vertueuse et philanthrope, en métropole comme aux colonies. En effet, il considérait les vieilles colonies comme de véritables départements français. Aussi demanda-t-il en vain l'application de plein droit de la Constitution de 1848 en dénonçant tout régime d'exception. De façon générale, il demanda quasiment à chaque vote de loi, l'application de celle-ci aux colonies, tout au moins aux ‘‘quatre vieilles''. Ainsi, sans jamais faire référence à la Constitution de 1795, Scho…

A population density grid for Spain

2013

This article describes a high-resolution land cover data set for Spain and its application to dasymetric population mapping (at census tract level). Eventually, this vector layer is transformed into a grid format. The work parallels the effort of the Joint Research Centre (JRC) of the European Commission, in collaboration with Eurostat and the European Environment Agency (EEA), in building a population density grid for the whole of Europe, combining CORINE Land Cover with population data per commune. We solve many of the problems due to the low resolution of CORINE Land Cover, which are especially visible with Spanish data. An accuracy assessment is carried out from a simple aggregation of …

JIMWLK evolution of the odderon

2016

We study the effects of a parity-odd "odderon" correlation in JIMWLK renormalization group evolution at high energy. Firstly we show that in the eikonal picture where the scattering is described by Wilson lines, one obtains a strict mathematical upper limit for the magnitude of the odderon amplitude compared to the parity even pomeron one. This limit increases with N_c, approaching infinity in the infinite N_c limit. We use a systematic extension of the Gaussian approximation including both 2- and 3-point correlations which enables us to close the system of equations even at finite N_c. In the large-N_c limit we recover an evolution equation derived earlier. By solving this equation numeric…

S=−1meson-baryon unitarized coupled channel chiral perturbation theory and theS01resonances Λ(1405) and -Λ(1670)

2003

The $s-$wave meson-baryon scattering is analyzed for the strangeness $S=-1$ and isospin I=0 sector in a Bethe-Salpeter coupled channel formalism incorporating Chiral Symmetry. Four channels have been considered: $\pi \Sigma$, $\bar K N$, $\eta \Lambda$ and $K \Xi$. The required input to solve the Bethe-Salpeter equation is taken from lowest order Chiral Perturbation Theory in a relativistic formalism. There appear undetermined low energy constants, as a consequence of the renormalization of the amplitudes, which are obtained from fits to the $\pi\Sigma\to\pi\Sigma$ mass-spectrum, to the elastic $\bar K N \to \bar K N$ and $ \bar K N\to \pi \Sigma$ $t$--matrices and to the $ K^- p \to \eta \…

Top-quark mass measurements using jet rates at LHC

2013

This work presents a new method to measure the top-quark mass in hadronic collisions[1]. The method uses the sensitivity of the tt̄ + 1-jet production on the top-quark mass. In detail we study the ℛ distribution defined as the tt̄ + 1-jet normalized cross section differential in the invariant mass of the total system and calculated at NLO accuracy. We prove that the ℛ distribution has a high sensitivity to the top-quark mass. Furthermore we investigate and quantify the impact of the dominant theoretical and experimental uncertainties. The results obtained show, that the method has the potential to be competitive in precision with established approaches and allows a complementary measurement…

Topical canrenoic acid. Quantification of the antiandrogenic activity in the hamster flank organ

1991

: The topical antiandrogenic activity of potassium canrenoate (CAK), compared with that of spironolactone (SP), was assayed in vivo in female golden Syrian hamsters whose flank organs were stimulated by subcutaneous administration of testosterone propionate. Sebaceous glands and hair were measured by a computerized image analyzer. Pigmented spots, sebaceous gland areas, and the diameter of hairs of the treated flank organs were smaller in the groups that received CAK (1·6 mg/day) and SP (0·4 mg/day). The authors' results showed that CAK may act as a topical antiandrogen on the hamster flank organ when applied in concentrations four times greater than the minimal active dosage of SP. Potassi…

Properties of hyperons in chiral perturbation theory

2009

The development of chiral perturbation theory in hyperon phenomenology has been troubled due to power-counting subtleties and to a possible slow convergence. Furthermore, the presence of baryon-resonances, e.g. the lowest-lying decuplet, complicates the approach, and the inclusion of their effects may become necessary. Recently, we have shown that a fairly good convergence is possible using a renormalization prescription of the loop-divergencies which recovers the power counting, is covariant and consistent with analyticity. Moreover, we have systematically incorporated the decuplet resonances taking care of both power-counting and $consistency$ problems. A model-independent understanding o…

Screening of Ovarian steroidogenic pathway in Ciona intestinalis and its modulation after Tributyltin exposure

2010

In this study, we have identified several ovarian steroids in Ciona with high similarity to vertebrate steroids and showed that cholesterol, corticosterone, dehydroepiandrosterone, estrone, estradiol-17beta, testosterone, pregnenolone, progesterone, have identical molecular spectra with vertebrate steroids. In addition, we have studied the effects of an endocrine disruptor (tributyltin: TBT) on these sex hormones and their precursors, ovarian morphology, and gene expression of some key enzymes in steroidogenic pathway in the ovary of Ciona. Ovarian specimens were cultured in vitro using different concentrations of TBT (10{sup -5}, 10{sup -4} and 10{sup -3} M). Ethanol was used as solvent co…

ANALISI DEI CONSUMI DI STUPEFACENTI E POPOLAZIONE DEL SERT DI TERMINI IMERESE FINALIZZATA ALL’ATTIVAZIONE DI UN PROGETTO EDUCAZIONALE

2013

Introduzione. In questo studio è stato preso in considerazione il consumo annuale di stupefacenti (metadone e buprenorfina) dal 2009 al 2012, da parte del Ser.T di Termini Imerese. Si è voluto indagare sulla tipologia di pazienti ambulatoriali per avviare un successivo progetto di prevenzione rivolto alle scuole. Materiali e metodi: I dati relativi ai consumi sono stati estrapolati dal programma di magazzino del polo di distribuzione di Termini Imerese, mentre i dati relativi ai pazienti sono stati ricavati dal Sistema Informativo Sanitario del Ministero della Salute consultabile dai dipendenti del Ser.T. Risultati: I consumi di metadone cloridrato flacone da 20 ml 0,1% sono progressivament…
