Hotshots: Glasgow Warrior Tommy Spinks

first_imgI wasn’t offered anything by Edinburgh or Glasgow when I left school but Simon Amor signed me. I learned a lot and have now joined Glasgow, which is a great opportunity for me.Have you enjoyed captaining Scotland U20?   I targeted the captaincy for the Six Nations and held onto it for the Junior World Cup. It is something I enjoy and take a lot of pride in. Home and away: Spinks has played at London Scottish LATEST RUGBY WORLD MAGAZINE SUBSCRIPTION DEALS RW verdict: This 20-year-old lock/back-row has impressed the Warriors and is a natural leader.Want to stay up to date with the latest rugby hotshots every month?

When did you start playing?I started mini rugby at North Berwick when I was about five. I played for North Berwick High School 1st XV when I was only a fourth year. Duncan Harrison, the coach at Fettes College, helped me get a scholarship there.What other sports have you played?   My mum, Joanna Spinks, was around fourth in the world at judo when she was 17 and I did judo until I was about ten. In my first summer at Fettes I did athletics and got bronze in the discus at the National Schools Championship.You have just finished a year at London Scottish?  last_img read more

A quantitative estimate of the ducted whistler power within the outer plasmasphere

first_imgFrom a statistical study of ductedwhistlers observed at Halley, Antarctica, in 1996, which had propagated on paths in the range L=2.5–4.5, we report mean occurrence rates, numbers of components per whistler, intensities, etc. for night and day conditions and in different seasons at solar minimum. We found an average whistler rate of and 3 components per whistler. Received whistler amplitudes were measured as a function of frequency and were in the range 2–40 fT, typically 10 fT at 4 kHz. Combining these results with a propagation model, we estimate mean whistler duct output powers to be around 1–10 mW, (≃0.1–1 mJ per whistler in the 3–5 kHz band). Inferred typical equatorial wave fields for ductedwhistlers of 0.3 pT led to estimated radiation belt lifetimes for 1–100 keV electrons due to gyroresonance with ductedwhistlers of 2×106 days. This compares with published lifetimes due to plasmaspheric hiss of order 105 days or less, and we conclude that, on average, lightning which enters and propagates in magnetospheric ducts, although known to cause pitch angle scattering and precipitation of trapped electrons, does not significantly affect the radiation belt fluxes in a statistical sense. We have compared our results with those from a similar study by Burgess and Inan (J. Geophys. Res. 98 (1993) 15,643–15,665). In a separate investigation of multi-component whistlers received in winter at quiet times, using the same methodology, we have found that the duct output power generally decreases with increasing L. This is consistent with previous theoretical work and parallels a similar experimental conclusion with respect to higher-frequency whistler-mode signals from VLF transmitters.last_img read more

Firkins announces shops closures and planned openings

first_imgTroubled bakery chain Firkins is closing three of its stores, just a few months after the chain was bought out of administration for the third time.However the West Midlands company – now trading as Newbridge Bakery – is set to open six stores in the region and insists it is trading positively.The 28-strong chain has closed shops in Kingstanding, Stourbridge and Harbourne in the last week, claiming they were “no longer appropriate for the needs of our growing business”. A spokeswoman said: “In Stourbridge, we are currently looking for new premises; in Harbourne, the deal has already been done for a relocated store that will be opening soon.” She added that the business was currently trading positively and that it was in advanced negotiations for a further five shops within the region. “We cannot reveal their location yet for commercial reasons.”There are no plans for further closures.The firm and 200 jobs were rescued by MD and sole director Ian Bolderston in December 2009, following his recovery of Firkins Bakery in 2006 and again in 2008.last_img read more
