Objectives To present an analysis of the infant mortality trends and causes of death in France from the beginning of the 1950s, neonatal (0-27 days) and post-neonatal mortality (27-364 days) being considered separately. Material and methods We used t

The melting curves of argon, helium 4, ice $({\mathrm{H}}_{2}\mathrm{O}),$ and hydrogen $({\mathrm{H}}_{2})$ have been measured from room temperature up to a maximum temperature of 750 K. This extends the previous determination of the melting lines o

Fourier-transform infrared and Raman studies are performed on $\mathrm{Ar}({\mathrm{H}}_{2}{)}_{2}$ compound single crystals over a large pressure (5--30 GPa) and temperature (30--300 K) range in a diamond-anvil cell. The effect of polarization on th

An extensive infrared absorption study of the compound Ar(H2)2in the range of pressure from 5 to 30 GPa, and between 30 K and room temperature is presented. This study has permitted the identification and assignment of high–frequency and low freque

This paper presents a new calibration of the pressure shift of the 7D0−5F0 fluorescence line of SrB4O7:Sm2+, in hydrostatic medium (helium) up to 124 GPa and in nonhydrostatic medium (H2O) up to 130 GPa. There is no quenching of the luminescence, i

Single-crystal x-ray diffraction has been performed on solid $^{4}\mathrm{He}$ from 1 to 58 GPa over the temperature range 46--400 K. The high-density properties of helium are pinned down: the hcp structure is stable apart from an fcc loop along melt
