LONDON, England:MVP Track Club head coach Stephen Francis is expecting ever-improving 200 metres sprinter Elaine Thompson to go much faster before the end of the season, after the 23-year-old’s impressive 22.10 (-0.3) personal-best and win at the Sainsbury’s Anniversary Games inside the London Olympic Stadium on Saturday.Francis also provided an update on 400m hurdling medal hope Kaliese Spencer, who has missed the last month or so of competition with a foot injury.Thompson, who had previously ran 22.37 at a Jamaica Athletics Administrative Association All Comers Meet in May, is seen as a strong contender for a podium spot at next month’s World Championships in Beijing, China, and looked like she belonged, out-powering established American sprinter Torie Bowie, 22.32, and Candyce McGrone, 22.70, to the line, in what was her first appearance in the 200m internationally this year, and only the second in her career.The timing of the sprinter’s personal best came as a slight surprise to Francis, who shared that she has been under a heavy training load in the past month at their training base in Italy.”We have been practising her technical running of the 200m a lot since the trials and, on one hand, it’s a little bit surprising that she ran that quickly because she has been having a very heavy training load since the trials ended,” Francis told The Gleaner. “We have had four really hard weeks and this is the time when it was least expected that she will run this fast, but on the other hand, it probably means that she will run a lot faster in four week’s time (at the World Championships), so we will see.”FOURTH-FASTESTThompson’s time makes her the fourth-fastest woman in the event this year and the eighth-fastest Jamaican in history behind Merlene Ottey (21.64), Grace Jackson (21.72), Veronica Campbell-Brown (21.74), Juliet Cuthbert (21.75), Kerron Stewart (21.99), Sherone Simpson (22.00), and Shelly-Ann Fraser-Pryce (22.09). Ottey would, of course, later change her nationality to Slovenian.Francis also pointed out the athlete’s ability to apply her training in competitive situations.”She ran as how she has been practising, and that’s a good sign,” Francis said. “Athletes who run as precisely as how they interpret what they are supposed to do will always do well, and I think she has got the message that all she needs to do, is do what she does in practice and allow everything else to take care of itself.”Meanwhile, Spencer was listed to compete in London over the weekend as well, but her name was removed from the 400m hurdles start list a couple days before the meet. She was also expected to run at another meet a few days ago, causing concern about her fitness going into the World Championships.Spencer won all three of the Diamond League meets she has competed in, but has not featured since June 11, but Francis assured that the Commonwealth champion will be ready for Beijing, where he expects her to do well.”She (Spencer) missed a couple weeks’ training; she had some issues with her foot, but she has started back, and because of that, you probably won’t see her run until the World Championships. Being as experienced as she is, I think it might be good for her.She will go into the World Championships a lot more focused, she will be in shape, she looks quite good so far, and I think she is going to run very well,” said Francis. “Nobody knows how everyone else will run, but I’m pretty sure Kaliese will run the fastest she has ever ran at a championships.”[email protected]
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.
