Cameroon have named a 26-man squad to begin camping next week ahead of their leg 2013 Afcon qualifier play-offs against Cape Verde in Yaounde.Newly appointed caretaker coach, Jean Paul Akono decided to put old wine in new skins by calling back a couple of old faces.Star striker Samuel Eto’o returns to the squad after almost nine-months absent as well as his fellow mates Benoit Angbwa anmd Jean II Makoun who exiled themselves from the team afte Eto’o was banned.Modeste Mbami, Mohammadou Idrissou, Pierre Wome Nlend have been recalled to international duty after over two years absence as well as Patrick Mevoungou.Cameroon face the danger of missing a second consecutive Africa Cup of Nations competitions should the fail to overturn a two-nil defeat suffered in the first leg in Praia.Cameroon squad Goalkeepers: Kameni Carlos Idriss, Ndi Assembe Guy and Mayebi Joslain.Defenders: Angbwa Benoit, Nyom Allan, Bedimo Henri, Bong Gaetan, Wome Nlend Pierre, Nkoulou Nicolas, Chedjou Aurelien, Kana Biyick Jean Armel, Nounkeu Dany and Matip Joel.Midfielders: Song Alexandre, Mbami Modeste, Olle Olle Junior, Mohamadou Idrissou, Emana Achille, Makoun Jean II, Overtoom Williams and Mevoungou Mekoulou Patrick.Strikers: Eto’o Samuel, Webo Achille, Aboubakar Vincent, Babanda Joel and Olinga Essono Fabrice.
The UV environment of the Beagle 2 landing site: detailed investigations and detection of atmospheric state
December 25th 2003 will see the Beagle 2 lander arrive at the surface of Mars in the Isidis region, allowing for the first time in situ measurements of ultraviolet (UV) flux directly from the surface of Mars through the use of a sensor designed as part of a miniaturised environmental package. The expected conditions the sensor will experience are studied here, and the detection signatures for phenomenon such as dust devils. H2O clouds ands near-surface fogs are presented. The beginning and end of mission surface fluxes show little variation, though the period towards mid-nominal mission does experience a maximum in total daily dose levels. Diurnal profiles are calculated highlighting the effects of increased scattering towards shorter wavelengths. A possible dust storm scenario is presented, and the effect upon component UV fluxes is shown to reverse the relative contributions of direct and diffuse components of the total UV flux. The presence of cloud formation above the landing site will be detectable though the observation of elevated diffuse/direct flux ratios. Near-surface morning fogs show a characteristic ‘dip’ in the morning profile when compared to clear mornings, allowing their detection on cloud-free mornings through post-event analysis of long term data. Predicted Phobos eclipses are investigated at each of the sensor centre wavelengths, and show greatest reduction in relative intensity at short wavelengths. Observations of near-miss eclipse events will also be possible, through monitoring of the diffuse UV flux. Dust devil encounters are shown to create a double minima lightcurve, with the depth of the minima dependent upon the total dust loading of the vortex. The effects of these changing conditions on DNA-weighted irradiances are investigated. Possible dust storms provide the greatest increase in biological protection, whereas expected cloud formations at the Beagle 2 site are found to offer negligible protection. Within just five minutes of landing > 95% of any Bacillus subtilis-like bacteria present on the surface of the craft will have lost viability.
