These compounds themselves may have no or very low bioactivity, but when light, especially UV-A light, is present they show strongly enhanced bioactivity [ 10, 25].
The iPhone 5 retains the 8 MP back camera on the iPhone 4S, but has improved low-light performance, and has a 40% faster photo capture than its predecessors, while having a purple hue when a strong source of light is present in the photograph.
If the box is not attached this way, or is plastic, or if no ceiling light is present, obtain a hanger kit (available from most fan manufacturers).
Average dark frames: we first acquire a sequence of frames when no light is present, and compute the average and standard deviation of each pixel and readout block.
This is needed for cropping, and to deal with beamstop transmission; Average dark frames: we first acquire a sequence of frames when no light is present, and compute the average and standard deviation of each pixel and readout block.
In a sighted mouse, it's the photoreceptor cells that tell the visual system when light is present.
When light is present, the channel opens, and positively charged ions flood into the cell.
Within rooms, closets and windows are also notably large and soft light is present throughout the hall.
Accessible from the menu and readable only when sufficient light is present, each map is marked with places of interest.
L = 1 when light is present, 0 otherwise; D = 1-L.
A spectroscopy method using light is presented in this research for monitoring marine water.
