The pion structure function is investigated in a simple pseudo-scalar coupling model of pion and constituent quark fields. The imaginary part of the forward Compton scattering amplitude is evaluated. We show that the introduction of non-perturbative effects, linked through a cut-off to the size of the pion, allows the reproduction of important features of the pion quark distribution function.

We measured particulate and dissolved organic carbon (POC and DOC), chlorophyll, oxygen, partial pressure of Co-2, pH, total alkalinity (TAlk) and particulate inorganic carbon (PIC) during a late summer cruise in the eutrophic Loire estuary. These parameters reveal an intense mineralisation of organic matter in the estuarine maximum turbidity zone (MTZ) that results in oxygen deficits (down to 20% of the saturation level) and high CO2 oversaturations (pCO(2) up to 2900 muatm). Several facts revealed the occurrence of carbonate dissolution in the Loire MTZ: large amounts of alkalinity were produced in the upper estuary, increasing its transfer to the ocean by 30%; the calculated saturation index showed a net undersaturation for aragonite and a slight undersaturation for calcite in the MTZ; and PIC decreased from 2.1% (% dry weight) in riverine suspension to 0.4% in the MTZ. A stoichiometric approach is used to assess the coupling between aerobic respiration and carbonate dissolution, where apparent oxygen utilisation, excess CO2, TAlk and dissolved inorganic carbon are compared quantitatively. About 20%, of the CO2 generated by respiration was involved in carbonate dissolution. The loss of PIC at the river-estuary transition quantitatively corresponds to the amount of authigenic calcite precipitated upstream in the highly eutrophic river. This suggests that CO2 exchange with the atmosphere along the eutrophic river-estuary continuum is buffered by carbonate precipitation in the autotrophic river and its dissolution in the heterotrophic estuary.

Pseudo-clubbing is different in many respects from clubbing. Its causes are multiple, mechanical, tumoral of sometimes congenital, while clubbing occurs mostly in association with hypoxia. Pseudo-clubbing is also characterized by an increased transversal and longitudinal curvature of the nail plate but the other anatomic considerations associated with clubbing are not present.

The structural and magnetic properties of the granular iron nitride-alumina composite materials: (FexN)(0.2)(Al2O3)(0.8) and (FexN)(0.6)(Al2O3)(0.4), fabricated using high-energy ball milling have been determined by using X-ray diffraction, Mossbauer spectroscopy, and magnetization measurements. The Mossbauer spectra, fit with a distribution of hyperfine fields between zero and 40 T. indicate that the weighted average field decreases with increasing milling time. The isomer shift increases with milling time because of a reduced iron 4s-electron density at the grain boundaries. Coercive fields as high as 325 and 110 Oe are obtained for (FexN)(0.2)(Al2O3)(0.8) at 5 and 300 K, respectively; the increase in the coercive field upon cooling indicates the presence of superparamagnetic particles. The coercive field increases with milling time because of the reduced particle size. The decrease in the magnetization results from the increase in both the superparamagnetic fraction and the concentration of surface defects with increased milling time. [less ▲]

The present paper describes a calibration of the ion effective temperatures as a function of the resonant activation amplitude in a quadrupole ion trap mass spectrometer. MS/MS experiments are performed on leucine enkephalin (M + H)(+), bradykinin (M + H)(+), (M + 2H)(2+), and (M + 3H)(3+), and ubiquitin (M + 11H)(11+). For each amplitude, the effective temperature is calculated as the temperature that would give the same dissociation rate constant as the one observed and is calculated using published Arrhenius parameters. The effective temperature is found to be linearly dependent on the activation amplitude on the range investigated. The dependence of the slope and of the intercept of the T-eff = f (amplitude) functions on the parent ion m/z is examined and an equation is derived to calibrate the ion effective temperature between 365 and 600 K Below 365 K, a deviation from linearity is expected. Above 600 1 the validity of the equation will depend on whether the rapid energy exchange limit is still reached. Calculating backward, the Arrhenius parameters from the measured dissociation rates using this calibration show excellent agreement with the published values. The calibration can therefore be used to determine Arrhenius activation parameters from dissociation kinetics under resonant activation in quadrupole ion trap mass spectrometers. [less ▲]

Properties of shooks ageing by a treatment in a solution of natural enzymes. A speeding up of the ageing of shooks is possible by a treatment with a solution of natural enzymes. However its repercussion on physical, mechanical characteristics of wood and on its absorption potential of an hydro-alcoholic solution must be tested. Normalized samples have been extracted from 150 shooks selected on a ring width criteria from three cooperages located on different supplying area in France. The three factors cooperage, ring width class and treatment are used for statistical analysis. The cooperage factor, reflection of the supply area of each of them, affect the young modulus and the modulus of rupture in static bending but not the other characteristics. The improvement of the wood properties is closely linked to the ring width increaseof the samples. The enzymatic treatment has no significant effect on physical and mechanical characteristics of oak wood, except on the hardness and, to a lesser extent, on the absorption potential. Considering the absence of negative effect on characteristics of shooks and the positive contribution of enzymatic treatment on their ageing, this treatment could bring a very interesting economical alternative permitting to avoid long lasting storage of the shooks before assembly.
