In our cities, trees must face many root stress. The most current are: •The chronic drought, bound to the narrowness of the plantation holes, to the packing of soil, to the asphalt cover of the surroundings ; •The asphyxic conditions, due to the same reasons ; •The chemical factors: inadequate pH, high salinity, deficiencies in nutrient elements, toxicity of others…; •The human aggressions: vandalism, injuries due to public works,… In spite of the diversity of the reasons, several morpho-physiological consequences are similar, notably on the depression of mineral nutrition and of water balance. Consequently, the proposed are aimed at the remediation of these effects. They are based on the correction of mineral deficiencies by injections of nutrient solutions, on the improvement of the biologic fertility by mycorrhiza inoculations, or on the aeration of soil structure. Some technics combine these different treatments. [less ▲]

Possibilities and limitations of the Prevost model for the modelling of cohesionless soil cyclic behaviour

The Prevost’s model is currently used to model cyclic behaviour of soils especially in earthquake engineering. The original model is able to capture the main features of cyclic behaviour: pore pressure build up and plastic deformation accumulation. But accurate modelling of laboratory tests requires improvements. Enhanced models exist but require a lot of parameters that make them cumbersome for practical purpose. A suction caisson, part of a tripod offshore foundation for wind turbines is modelled. Possibilities of the Prevost’s model are highlighted compared with a classical Drucker-prager model. [less ▲]

Possibilities for rutile extraction from Norwegian eclogite by flotation

Scientific conference (1993)

Preliminary flotations tests towards rutile extraction from Norwegian eclogites (Verving deposit) have been carried out. Various sulfonate type flotation reagents (produced by Hoechts) have been tested ... [more ▼]

Preliminary flotations tests towards rutile extraction from Norwegian eclogites (Verving deposit) have been carried out. Various sulfonate type flotation reagents (produced by Hoechts) have been tested. Selectivity between rutile/pyroxene has been targeted. Rutile separation from pyrite and garnet has been further identified as principal problem. [less ▲]

The possible appearance of a second period in the WN 5 star EZ Canis Majoris

in Astronomy and Astrophysics (1987), 178

Previously published photometric data on EZ Canis Majoris are reanalyzed. It is shown by different techniques that a sine-wave type periodicity close to one third of the claimed period of P = 3[SUP]d[/SUP ... [more ▼]

Previously published photometric data on EZ Canis Majoris are reanalyzed. It is shown by different techniques that a sine-wave type periodicity close to one third of the claimed period of P = 3[SUP]d[/SUP].766 may also be present in what was considered as peculiarities in the lightcurve. The data available do not allow to known if this second period is precisely equal or only close to one third of P nor if there is some dependence between the two. In any case, the mere possible existence of such a second period is an interesting fact in the discussion concerning the possible existence of non-radial pulsations in some WR stars. [less ▲]

The possible biperiodicity of WR 40

in Astronomy and Astrophysics (1990), 231

Strong arguments are presented in favor of the simultaneous presence of two periodicities in the variability of the Wolf-Rayet star WR 40. The frequencies are nu(A) = 0.16/d and nu(B) = 0.40/d. Some ... [more ▼]

Strong arguments are presented in favor of the simultaneous presence of two periodicities in the variability of the Wolf-Rayet star WR 40. The frequencies are nu(A) = 0.16/d and nu(B) = 0.40/d. Some uncertainties remain concerning the choice of the actual one-year alias. On the basis of a detailed statistical analysis, reliable evidence that the variability related to nu(B) could be coherent is also presented: this points out nu(B) as a possible fundamental frequency linked to the 'core' of WR 40. No firm conclusion could be drawn about nu(A), suggesting that it could be a recurrent quasi-periodicity or a second order periodicity (e.g., a beat frequency). The two frequencies are sometimes hidden by the white noise, or slightly correlated, random process that constitutes the third component of the variability of WR 40. [less ▲]
