The whirring of aeroplanes overhead, the rattle of machine-gun fire, and finally the frightful thunder of a gun in the field at the bottom of our garden, would all have served to distract a mind less happily engaged; but as it was, with curtain closely drawn to prevent the escape of light, I consorted that evening with Cardinal Manning, Thomas Arnold, Florence Nightingale, and General Gordon.
b Schematic cross section, showing escape of light from top surface and sidewall of LEDs.
It is observed that that the power ratio decreases near the acceptance half-angles of the designed concentrator due to the optical losses caused by scattering and escaping of light from the edge of the receiver.
AlGaInP LEDs with a roughened surface, textured surface, and truncated pyramid geometry were reported to enhance the LEE by increasing the critical angle and the probability of escape of emitted light from an air/semiconductor interface [8 10].
The asymmetric gratings provide higher light trapping efficiency than symmetric ones because the asymmetric one suppress the escape of internally reflected light in the silicon wafers.
Her glamorous escape to the city-of-light merely set the scene for her homecoming and marriage to a streetwise local boy.
She writes about the futile explorations and attempts to escape, the incremental loss of light as one by one the battery-powered lamps were exhausted until the men waited in impenetrable blackness, the acceptance of death by some, the rejection by others, the thirsts so great that men drank urine, the emergence of unexpected strengths and finally the delirious joy of salvation.
Darwin became interested in plant movements such as orientation towards the sun or the escape from the excess of light provoked or influenced by blue-light, and dedicated a complete volume to them, in which he described the use of a yellow-orange solution of potassium dichromate as a filter to eliminate phototropism (Darwin, 1880).
Downtown residents, who escaped to the City of Light of Midtown and above, often gorged as if they did not know where their next meal was coming from.
But Tautou, cast in the movie as a "dry and hard and sometimes poison-like woman," escapes from the pool of light that typically surrounds her.
As part of a lighting audit, Owens visited every outside light on the isle, which covers 5.5 sq km (2 sq miles), and made recommendations to reduce the amount of light escaping from them into the sky.
