Light experiments

For a circularly polarized light experiment, one can measure the cross sections for either right (r) or left (1) polarized scattered light. Suppose that right polarized light is made incident on a Raman active sample. The general expressions for the Raman cross sections are [176]... 

Fig. 1 Location of sampling sites in the Ross Sea, Antarctica, where seawater and plankton were collected for the experiments described in this paper. Seawater and resident plankton used in the shipboard iron-light experiment were collected at station A uncontaminated seawater used in the laboratory iron experiment was collected at station B the P. antarctica culture used in the laboratory iron experiment was isolated from water collected at station 25...

The light output of electric lighting gradually decreases due to stain buildup on lamps and covers during operation. Roadway, and especially tunnel lighting, experiences a large amount of contamination due to dust, carbon particles found in vehicle engine exhausts and other airborne contaminants,... 

Temporary loss of vision. Bright light experience. No pain. External exam normal. Internal exam normal. Glare, dazzle, or flash-blindness. (Low dose laser.) None. Return to duty. 

Note. N.B. In the experiment as here shown, a tiny piece of TOtassium must be used instead of phosphorus, since tba Canale has not been previously lighted. Experiment cuefuUy beforehand. The potassium is best conceated in the candle wick. 

In a short note Volta says that well-burnt charcoal was superior to silver or gold when in combination with tin in producing galvanic effects, and that the contact of tin foil and a silver coin in the mouth and applied to the eye produced sensations of taste and light. Experiments showed that the electric fluid passed when pieces of metal of different kinds are in contact with all kinds of non-animal bodies, also with other humid bodies (sostanze umide) such as paper, leather, cloth, etc., soaked in water, or best of all with water. Metals in such circumstances are not only conductors (deferenti) but also true movers and exciters of electricity (veri motori ed eccitatori di elettricita), which he...
