the stomach empties food into the lumen of the small intestine
‘That said, you can still go down and buy a fluorescent lamp for a few dollars that puts out thousands of lumens ,’ he says, compared to the 30 to 60 lm emitted by current white LEDs.
These cells were found minimally invading the liver, by direct extension, but were readily found within the lumina of blood vessels and lymphatics.
It comes with two lamps, one with 125 lumens output (one hour battery life) while the other offers 225 lumens (20 minutes of life).
In almost every case the electronic ballast ensures the highest mean lumens per watt, both by inherent efficiency and, in the case of metal halide lamps, by better lamp power management.
What we can buy is a compact fluorescent bulb that only uses 20 watts of electricity and produces 1,000 lumens , the same as a 100-watt light bulb.
Even on cloudy days, a tubular skylight can provide at least as much light as a 100-watt incandescent bulb - about 1,200 lumens .
The bulbs are very bright (measured in ‘lumens’ as in the more lumens the brighter the projector), allowing the images that they project to be seen even in well-lit rooms.
Autopsy findings confirmed luminal narrowing of bronchioles by scarring, which is a histopathologic features of bronchiolitis obliterans.
Histologically, the disease is characterized by a bizarre population of neoplastic cells that are found systemically within the vascular lumina .
