(4) Mayor Boris Johnson, whose default setting has been relentless and sometimes improbable cheerleading in the face of serious concerns and minor niggles, promised with typical restraint that as the flame "spreads through the city its radiance will dispel any last clouds of dankness and anxiety that may hover over some parts of the media".

(7) This may in part be related to the intrusion of the blue-sensitive mechanism at the upper radiance range.
(8) The obtained constancy ratios were attributed to the role of distance estimation in the determination of colour appearance, an effect that is presumably masked under normal viewing conditions, where long viewpaths are necessary to produce significant radiance changes.
(9) All the cone mechanisms were in compliance of Ricco's law, summing target radiance linearly over a certain range of target diameters with an average slope of 2.4.
(10) "If you look at it as an exhibition, there is a lot of radiance and luminosity and jewel-like colours," she say.
(11) A small patch of achromatic light viewed within a large achromatic surround appears gray or black when the radiance of the surround is well above that of the patch.
(12) A study is reported of colour appearance in situations where the spectral radiance of an object changes significantly with viewing distance.
(13) Many times over the past decade and in the middle of making other films – All or Nothing , Happy-Go-Lucky , Another Year – Mike Leigh and his cinematographer, Dick Pope, would look at the sky and then at one another and say: “Oh God, we must make our Turner film.” A particular light, a moment’s radiance, a sunset – any of these might set them off.
(14) A rapid clinical protocol to assess the radiance response function of the SWS cone ERG is described.
(15) When changing the radiance ratio 630 nm-531 nm of the stimulus, the normal subject exhibited a P-ERG to all stimuli with only a relative amplitude minimum at a distinct radiance ratio, whereas the color-deficient observers failed to show a P-ERG at some color contrast 630 nm-531 nm, the radiance ratio of which was different in the protan and deutan.
(16) The responses of the phasic ganglion cells go through a minimum at relative radiances very similar to that predicted from the V lambda function.
(17) The diffusion length was also determined from radiance versus depth measurements.
(18) Biological weighting functions were used to calculate the blue-light radiance and the weighted UV irradiance.
(19) Considering a negative phototaxis as a stimulus reaction to narrow - or wideband monochromatic radiance of varying ranges of wavelengths and different irradiance it was established that both unfed and engorged I. and II.
(20) Different color sensations were generated by two areas in a complex scene, even though both areas sent to the eye the same 656-nanometer radiance that excited the long-wave cones and excited only the rods.
(1) His body was found on the pavement of Portman Avenue, in East Sheen, an affluent west London suburb, shortly before 7.45am on 9 September last year, just after flight BA76 from Luanda, the Angolan capital, passed overhead.
(2) In vitro pure-culture studies were conducted to assess growth and sheen formation of groundwater bacteria on M-Endo medium incubated under reduced oxygen concentrations (0, 4, 8, 12, and 16%).
(3) Sheen accused the Danish authorities of being complicit in the “brutal slaughter”.
(4) The colour to channel for next season is, in fact, not matt buttercup yellow but the gold-foil sheen best explained as the colour of the toffee penny in a box of Quality Street.
(5) The engines, gearboxes and even the doors now have a complexity that sees them constructed elsewhere, but the transformation on this line of the dull sheen of aluminium parts into a moving vehicle at the other end is still something to behold.
(6) The absence of China and India at the highest level will take some of the sheen off, but they can possibly come back on board if leaders of industrialised countries make serious commitments about what they are going to do to mitigate emissions and help developing nations.
(7) The president, played by Martin Sheen, had to hustle to find new neckwear from someone on his staff with less than a minute to air.
(8) Suspect sheen-forming colonies were analyzed to determine purity and identity of cultures.
(9) Vinterberg's version stars Carey Mulligan as headstrong Bathsheba Everdene, while Michael Sheen, Tom Sturridge and Matthias Schoenarts play the contrasting suitors who jockey for her attention.
(10) In pride of place above the fireplace sits a shot of his sons, alongside one of him interviewing Mandela and a US magazine cover which followed the marathon 1977 confrontation with Richard Nixon that earned him a place in history - and provided the subject matter for an award-winning play that will this year become a film starring Michael Sheen as Frost and Frank Langella as Nixon.
(11) A ctor Michael Sheen looks a bit like a lot of people and sooner or later usually ends up playing them.
(12) Writer Feargus O’Sullivan thinks of the presence of artists and creative workers as adding a “cursory sheen to a place’s transformation”, describing the process as “ artwashing ”.
(13) If you fly over the Gulf today, you will see the sheen of oil everywhere .
(14) Dilute suspensions of normal erythrocytes exhibit a pearl-like sheen (nacre) when subjected to flow.
(15) Having had to give up Twitter (she's an avid user), her replacement social exchange will now be with the likes of Jedward and Kerry Katona, the most recognisable of the celebrities, or bare-knuckle fighter Paddy Doherty from My Big Fat Gypsy Wedding, a paparazzo, a male model and a couple of actors (American superstars Charlie Sheen, Pamela Anderson and Mike Tyson were conspicuous by their absence).
(16) The ophthalmoscopic appearance showed a segmental, grayish metallic sheen in association with bone spicule pigmentation, which radiated from the disk along the temporal vessel arcades and joined temporal to the macula.
(17) Stephen Sheen, Cardiff • Post your answers – and new questions – below or email them to nq@theguardian.com .
(18) The actor Michael Sheen, best known for playing Tony Blair in a series of TV dramas and the award-winning film The Queen, has delivered a passionate defence of the NHS against “bland” politicians in thrall to the market from both Conservative and Labour parties.
(19) As a teenager, he was as much of a presence in American magazines for teenage girls as Corey Haim and Charlie Sheen.
(20) These were quite dark, with or without a metallic sheen, and closely resembled the colonies of lactose fermenting Escherichia coli on EMB agar.
