In my lifetime, the "spot fly" was found virtually all over Britain, but in recent decades it has declined catastrophically: between 1967 and 2013, it dropped in numbers by 89 per cent, and this summer appears to have been quite calamitous for the bird.
DO concentration was monitored via fluorescence lifetime sensor spots on the vessel vertical walls.
The devices used commercially available fluorescence lifetime sensor spots to measure DO and pH, while transmitted 600 nm light intensity was measured vertically through the reactor chamber to calculate optical density (OD), and hence cell density.
Somewhere between the stop frame (or bullet-time, or bullet-frame, or whatever camera technique they use) and the quasi-philosophical lyrics about feeling out of place in one's lifetime, you'll spot what they're trying to flog at one minute and three seconds.
White's real tools were a lifetime spent in one spot and a calling that led him daily on foot and horseback over his parish.
After all, Andy famously wrote, "Good business is the best art," and appeared in all kinds of ads in his lifetime (see his Braniff spot with boxer Sonny Liston below).
Although I have an oft-repeated (in the vain hope of garnering a lifetime's supply) soft spot for the Bird's variety, even I have to admit that, for a special occasion like Christmas, the real sort is probably more appropriate.
The sensor dish reader (SDR; PreSense) monitors pH in real-time in special plates (HydroDish®) using a non-invasive technique that detects the luminescence lifetime of a sensor spot at the bottom of each well that is dependent on the pH of the surrounding sample.
In addition, the organization has asked channels like ABC, CBS, NBC, CNN and Lifetime to run the spots as free public service advertising through the end of the year.
Each campaign is also beginning to put more spots on Lifetime, and a McCain media buyer recently lamented that the Food Network did not accept political advertising.
