    Seismic versus aseismic deformation in Iran inferred from earthquakes and geodetic data

    International audienceA combined analysis of the geodetic strain-rate field and the strain-rate field deduced from the seismicity allows us to define the style of deformation and to distinguish seismic from aseismic deformation. We perform this analysis in Iran where the present-day tectonics results from the north–south convergence between the plates of Arabia to the south and Eurasia to the north. The data consist of velocities measured with a GPS network of 28 benchmarks and of instrumental and historical earthquake catalogues. The axes of the seismic strain-rate tensor have similar orientations to those deduced from the GPS velocity field. This indicates that the seismicity can be used to improve GPS information on the style and the orientation of the deformation. Comparison of seismic and geodetic strain rates indicates that highly strained zones experience mainly aseismic deformation in southern Iran and seismic deformation in northern Iran. A large contrast is observed between the Zagros (less than 5 per cent seismic deformation) and the Alborz–Kopet-Dag regions (more than 30–100 per cent seismic deformation). The distribution of the seismic/geodetic ratio correlates with the distribution of large earthquakes: intensive, low-magnitude seismicity is observed in the Zagros whereas the largest earthquakes occur in northern Iran. The contrast of seismic deformation between the Zagros and peri-Caspian mountains is confirmed considering 300 or 1000 yr of seismicity rather than 100 or 200 yr

    Neste texto, apresentam-se algumas reflexões a respeito da necessidade do indivíduo aprender a conviver com aspectos contraditórios da condição humana. Para isso, colocam-se os mitos e, em especial neste artigo, o mito de Dioniso, como um modo poético de captar e expressar os conflitos do homem no contato com a realidade mental.<br>This paper considers the necessity of the individual to learn to live with the contradictory aspects of human condition. In this sense, myths are placed, especially the myth of Dionisos, as a poetic form to express man's conflicts in contact with mental reality

    À propos du non-profit : rapport du quatrième symposium annuel d’éthique transfusionnelle de l’Institut national de la transfusion sanguine [Not-for-profit: A report from the fourth annual symposium of ethics held by the National Institute for Blood Transfusion (France)]

    The not-for-profit issue has been debated in November 2016 in Paris; this issue is one of the four canonical pillars of ethical blood donation. It is intimately bound to benevolence though it is distinct, as not-for-profit calls for institutions while benevolence calls for individuals. It is indeed intended that voluntary blood donors do not benefit from their donation and are thus non-remunerated. Not-for-profit is essential since it refers to the public character of blood as a putative public resource aimed at being shared as a tribute of solidarity. A central question however is linked to the capacity- or not -of public sectors to ensure that blood components are universally available, with special mention to plasma derived drugs, without the contribution of the for profit, private sector

    This occasional paper contains information gathered by the National Drug Treatment Reporting System (NDTRS), an epidemiological database on treated drug misuse complied by the Drug Misuse Research Division (DMRD) of the Health Research Board (HRB). The data shows that between 1996 and 1999 the number of drug users presenting for treatment within the Southern Health Board (SHB) remained fairly stable at less than 300. This changed in 2000, with an increase of 66% to 429 clients. This was in part was due to an increase in service provision and also an increase in drug use. The socio-demographic data showed that the typical client is male, in his early twenties and living in the family home. Cannabis is the main drug causing problems (65% in 2000), with ecstasy the second most commonly used (15% in the same year). Opiate use rose from 5% in 1996 to 10% in 2000
