Sur la torsion de la distribution ordinaire universelle attachée à un corps de nombres

International audienceWe study the torsion subgroup of the universal ordinary distribution related to a general number field. We describe a way to control this subgroup. We apply this method to the special case of an imaginary quadratic field, and we give examples of such fields where these torsion subgroups are non-trivial

Appraisal of the Aquifer Hydraulic Characteristics from Electrical Sounding Data in Imo River Basin, South Eastern Nigeria: the Case of Imo shale and Ameki Formations

Twenty three vertical electrical sounding data sets were obtained from various parts of the study area in the middle Imo River Basin, using a maximum current electrode separation of 1000 meters. The litho-stratigraphic units within the study area are Imo Formation & Ameki Formation. The sounding data were analyzed with the RESIST software to delineate the sub-surface layering. Three soundings were made at existing boreholes for comparison. The concept of Da-Zarrouk parameters (transverse unit resistance and longit udinal conductance in porous media) was used to determine aquifer hydraulic characteristics. The following values of hydraulic conductivity and transmissivity were obtained for the various formations: For aquifers located within Imo Formation the mean of the hydraulic conductivity Kmean= 2.65 m/day, while the mean of the transmissivity Tmean=46.63m2/day; Kmax= 3.13m/day, Kmin=2.09m/day; Tmax=87.68 m2/day,  Tmin=15.54 m2/day. For aquifers located within Ameki Formation, Kmean=2.70m/day; Tmean=80.59 m2/day; Kmax=4.65m/day; Tmax= 167.14 m2/day; Kmin=1.25m/day and Tmin=6.08 m2/day. The aquifer thicknesses are (15m—49m) for Imo Formation, (2m—55m) for Ameki Formation.   Keywords: Imo River Basin, aquifer hydraulic characteristics, Dar-Zarrouk parameters

Cat epididymal semen cryopreserved with and without vitamin E: effect on sperm parameters and lipid peroxidation

The aims of this study were to investigate: 1) if the addition of \u3b1-tocopherol (vitamin E) in three concentrations (0.3, 0.6 and 0.9 mM) is able to preserve spermatozoa integrity after thawing and 2) the effect of \u3b1-tocopherol supplementation on lipid peroxidation. Fifty four domestic cats were used in this study constituting 18 pools (3 cats per pool). Each pool was submitted at four experimental groups: group 0 (control) \u2013 epididymal sperm were frozen with a commercial Botucrio\uae extender; group 0.3, group 0.6 and group 0.9 \u2013 the extender was supplemented with 0.3, 0.6 and 0.9 mM of \u3b1-tocopherol, respectively. Each semen sample was evaluated for motility, progressive forward motility, morphology, sperm viability (plasma membrane integrity-PMI), hypo-osmotic swelling test (HOST), before and after thawing. The evaluation of lipid peroxidation reaction by Thiobarbituric Acid Reactive Substances (TBARS) test was performed on thawed semen only. Results demonstrated that there was no significant difference between control and the three \u3b1-tocopherol groups with regards to motility and progressive motility after thawing (P > 0.05). As expected, in fresh samples viability was significantly higher than in all the cryopreserved groups in which there was no positive influence of any of the \u3b1-tocopherol concentration used. Lipid peroxidation was higher in the supplemented groups 0.6 and 0.9 mM of \u3b1-tocopherol than in control and in 0.3 mM group. In conclusion, the addition of \u3b1-tocopherol to the commercial extender had no positive influence on reduction of lipid peroxidation. This topic deserves further investigations to better understand the effect of cryopreservation procedures on epididymal spermatozoa and to establish adequate strategies to counteract sperm cryodamages

Dynamique des nombres et physique des oscillateurs

24 pagesWe consider the superheterodyning system discovered by Armstrong and Schottky in 1924. This system is the basic piece of any communication system. We prove that the frequency spectrum of this system is governed by arithmetical rule. We provide a number theoritical framework which allows us to predict all the particular features of the experimental frequency spectrum. We also introduce a new natural dynamical system on numbers and study its first properties

Horizontal Structure of the Upper Ocean Velocity and Density Fields in the Western Equatorial Pacific Warm Pool: Depth Range from 20 to 250 m

Wavenumber spectra of velocity and density fields in the western equatorial Pacific warm pool on scales 6–120 km are estimated using the shipboard survey data collected during the TOGA Coupled Ocean–Atmosphere Response Experiment (COARE). The spectra are averaged over three depth intervals: 20–60, 60–110, and 110–250 m (corresponding to the Yoshida jet, the South Equatorial Current, and the southern edge of Equatorial Undercurrent). The velocity spectra are corrected for the mean flow shear advection, which is important under conditions of low gradient Richardson number (Ri). After that, both velocity and density spectra are consistent with an internal wave spectral model including a random component (equatorial version of the Garrett and Munk spectrum) and a tidal component (the Feng et al. tidal model). Tidal peaks, previously found by other COARE investigators as being prominent on the ‘‘moored’’ spectra (i.e., on the spectra derived from mooring data), appear to be much less significant on the ‘‘towed’’ spectra (i.e., on the spectra derived from shipboard surveys). The model and observations reveal some directional anisotropy of the towed velocity spectra depending on Ri

Density, refractive index, apparent volumes and excess molar volumes of four protic ionic liquids + water at T=298.15 AND 323.15 K

Densities and refractive index of binay mixtures of water with four protic ionic liquids, based on ammonium and fatty acids, were measured at 298.15 and 323.15 K, under atmospheric pressure. Apparent and excess molar volumes were obtained by experiments and fitting data to the Redlich-Meyer (RM), Redlich-Kister (RK) and Prigogine-Flory-Patterson (PFP) equations. The molar volume values were high, suggesting strong ion-solvent interaction. The same interaction also became stronger as the temperature increased. Excess volume values were negative, indicating that packing efficiency ability or attractive interactions occurred in mixtures of ionic liquid + water. The errors (AARD) for the properties in excess were in the range of 1.8% to 7.2%. The PFP error for the apparent volume was in the range of 0.34% to 0.06%, lower than the RM error for the same property, which was in the range of 0.70 to 1.55%. The Gladstone-Dale model was applied to correlate the refractive index of the binary mixture with the density from the values of both pure components323671682FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP2011/19736-
