  1. haha are you calling me simples:blushing: more reading needed me thinks:thumbup:
  2. I thought the age od trees generally broke down into the rule of 3's whereby example say an oak lived to 900 years then it would spend 300 years growing, 300 years maturing and in full vigour and 300 years dying.. I know it is quite a general term and could be applied to most trees but is this not the case? Trees, with man's intervention can carry on living (old pollards) like that Lime somewhere, i don't know where, thats reported to be nearly 2000 years old due to re-pollarding. Just wondered thats all as you state in the 2nd or 3rd paragraphs that the longest part of a tree's lifetime is that of decay.
  3. west lancs here, put down 6-8 inches last night, still snowing now
  4. i keep basting mine in all the fat, i've been known to even add a little extra goose fat:blushing: but seems to work although constant basting takes ages to cook! think the equation is 10-15mins per kg then an extra 60-90 mins depending on the oven
  5. turkey ain't dry if you cook it right!
  6. Karma all the way on this one:thumbup: Nice deed, which should be taken upon us by all at all times of the year and not just christmas. Good will to all mankind an all that! Merry Xmas everybody
  7. what roles do fungi play on carbon sequestration within the tree in relation to these reactions? orwould that be another thread entirely?
  8. its the same hear, some oaks are still on the verge of green and the alders too. I've even seen some holly thats still green and not shed its leaves yet:blushing:
  9. they would make awesome wall canvasses/artwork:thumbup:
  10. how come you didn't offer to do it or was he really pushy about doing it himself?
  11. i'd have finished off with the hedgecutters:lol: haha good job!
  12. in this thread hama?? http://arbtalk.co.uk/forum/general-chat/14708-beranek-redwood-old-growth-videos-parts-1-2-3-a.html#post262206
  13. enjoy your toy (when you get it) sounds like you've deserved it! Sorry i couldn't find the right one for ya but looks like ya managed it in the end, nice one:thumbup:
  14. yeh going doing some conny bashing and small pop removal for a bit of extra cash, only got 1 assignment left so this weekend kinda became free!
  15. i did my arb principles one, went ok i think
  16. doh! organised work this satdy rob, otherwise you know i'd help out!
  17. might be pricey if these the ones, no price "please call"! Zeiss Supra 55VP - For Sale at Used-Line
  18. you done ya exams mate? hpw did they go, did one of mine monday!
  19. think this is the zeiss one http://www.zeiss.com/C125716F004E0776/0/69474FD972132558C1257171004C1B7F/%24File/Innovation_13_49.pdf
  20. Philips XL30 FEG This SEM (acquired 1996) has a field emission electron gun (FEG) for high resolution, with an Oxford Instruments CT1500 HF cryo-stage for cryo-fixed samples and freeze-fracture work. This instrument is equipped with a 120 roll film camera for analogue image capture, but can also capture digital images of up to a maximum of 3k by 4k pixels. The system is computer controlled and fully networked to permit easy transfer of images. Zeiss Supra 55 VP FEG A second high-resolution SEM was installed in 2004. It is a Zeiss Supra 55 VP FEG SEM with a Gatan Alto 2500 cryo system for cryo-fixed samples and freeze-fracture work. It also has a Deben CoolStage which is basically a Peltier stage and can be used to hold samples at specific temperatures in the range +50°C to -25°C. The microscope also has variable pressure (VP) mode which allows imaging at low vacuum (in the range 2-133Pa). This, in combination with the CoolStage, helps reduce charging artefacts and permits some samples to be imaged without sputter-coating and at ambient, or close to 0°C, temperatures which would otherwise have had to be cryo-fixed if imaged at high vacuum, such as insects and even some leaves. When working in VP mode, the microscope uses a special detector (VPSE) for imaging. In addition to the normal secondary electron (SE) detector, there is also an in-lens detector and therefore this microscope offers higher resolution than our other SEM. It has no camera so all images must be captured digitally. The system is fully computer-controlled and has a CD-writer for users to write their images to a CD before leaving the microscope room.
