Consequently, the combination of labels which can be used depends on the wavelength of the lamp(s) or laser(s) used to excite the fluorochromes and on the detectors available.

Tom turned the lights off.

Don't forget to turn off all the lights before going to bed.

At night, I do not want to see flashes of torches.

And when we made a solution of this, tagged with the fluorescence and injected in the body of a mouse, their nerves literally glowed.

His first public display of a neon lamp took place on December 11, 1910, in Paris.

We were not allowed to talk or turn on flashlights. So we put on our life jackets in the darkness.

Claudes started working on neon tubes which could be put to use as orbinary light bulbs.

Many people find it annoying that CFLs take time to warm up. Or they believe that their light is funny.

Latimer worked as an engineer, a draftsman and an expert witness in patent litigation on electric lights.

In the 1970s, emissions of chlorofluorocarbons (CFCs) in industrial applications were linked to destruction of the ozone layer.

Or they worry that the bulbs can spread poisonous mercury if they break. For some people, energy efficient bulbs can trigger epileptic seizures and migraines.

But proponents of phasing out access to incandescent bulbs argue that they know better.

This is clearly not true for those who suffer from migraines or epileptic seizures because of the new bulbs, or for those who are seriously worried about mercury, or for those who have other reasons for preferring incandescent bulbs.

While other materials can be used, most models use a fluorescence based substrate because it is very easy to detect, even at the single molecule limit.

Why, then, is it even necessary to outlaw the old bulbs? The reason is that monetary cost is only one factor.

An advantage of rubber bulb devices is that they provide visual feedback (via a gauge) of how much pressure is being applied.

What needs to happen now is further development of our technology along with development of the instrumentation that allows us to see this sort of fluorescence in the operating room.

The three companies blew the trumpets, and broke the pitchers, and held the torches in their left hands, and the trumpets in their right hands with which to blow and they shouted, The sword of Yahweh and of Gideon!

And the three companies blew the trumpets, and brake the pitchers, and held the lamps in their left hands, and the trumpets in their right hands to blow withal and they cried, The sword of the LORD, and of Gideon.

And in places where lights are not used very often, a lower price incandescent bulb can cost less overall than the energy efficient alternative.

Another example is incandescent light bulbs, which emit only around 10 of their energy as visible light and the remainder as infrared.

The green fluorescent protein (GFP) is a protein composed of 238 amino acid residues (26.9 kDa) that exhibits bright green fluorescence when exposed to light in the blue to ultraviolet range.

Nevertheless, the increased trend toward the use of hydrocarbons, ammonia, carbon dioxide and low global warming potential fluorocarbons had been noted in various applications, as had been the increasing trend to use secondary loop systems to reduce refrigerant charge and emissions.

The current attempt by Republicans in the US Congress to roll back America s effort to ban incandescent bulbs has revived this discussion.

Thus, on a straightforward cost benefit basis, it seems to make sense for most people to switch from incandescent bulbs to the new, greener technology.

The one thing we need to do is we have to replace these inefficient incandescent light bulbs, florescent lights, with this new technology of LED, LED light bulbs.

Polish adventurers entered the town of Pripyat in the Chernobyl Exclusion Zone and turned on lights for the first time since the 1986 nuclear disaster at the Chernobyl Nuclear Power Plant.

What we get out of this project is we get support for our own work, as well as an experience of actually contributing to the environmental movement in a way other than just screwing in new light bulbs.

My household uses CFLs, and I enjoy knowing that I am causing fewer CO2 emissions and spending less money.

(g) Fluorescence assessment of the effect of radiation on the fluorescent properties of yeast cells in space and study of the possibility of using yeast cells as biological sensors to detect DNA deterioration caused by radiation.

When the equipment's halogen lamps, worth 12 per unit, had been used up, a professor tried to obtain new lamps from the company in Spain, but this was refused once it was discovered that she was of Cuban nationality.

As a result, parents resort to local solutions like tying hot water bottles around their babies' bodies, or placing them under light bulbs like the ones you see here methods that are both ineffective and unsafe.

Setting aside other possible objections to this view, there is the problem that it presumes that all incandescent bulbs are worth less than 7 ton of CO2.

Whether it is through low energy housing, planting trees, teaching children to respect the environment, boycotting incandescent lightbulbs, or wrapping gifts in old newspapers, we have the opportunity to lead by example.

It was powered by a power station consisting of two waterwheels that produced an alternating current that in turn supplied seven Siemens arc lamps at 250 volts and 34 incandescent lamps at 40 volts.

Experimental observation In experimental biophysics, the activity of molecular motors is observed with many different experimental approaches, among them Fluorescent methods fluorescence resonance energy transfer (FRET), fluorescence correlation spectroscopy (FCS), total internal reflection fluorescence (TIRF).

For example, a gene from a jellyfish, encoding a fluorescent protein called GFP, or green fluorescent protein, can be physically linked and thus co expressed with mammalian genes to identify the location of the protein encoded by the GFP tagged gene in the mammalian cell.

The up front cost is a factor, too, especially for those on low budgets. And in places where lights are not used very often, a lower price incandescent bulb can cost less overall than the energy efficient alternative.

While CFLs are more expensive to buy, they are much cheaper over their lifespan, because they use much less energy (even more so with the cost of CO2 factored into taxes on electricity).

I won't go into this very much, but our technology, besides being able to tag tumor and metastatic lymph nodes with fluorescence, we can also use the same smart three part molecule to tag gadolinium onto the system so you can do this noninvasively.

So if I take this salt dough, again, it's like the play dough you probably made as kids, and I plug it in it's a two lead battery pack, simple battery pack, you can buy them at Radio Shack and pretty much anywhere else we can actually then light things up.

CFLs and other advances can take us part of the way, but there are massive technological hurdles to overcome before fossil fuels generally become less attractive than greener alternatives.

According to the information reported on this subsector, the efficient lighting option has high potential for cost effectively abating GHGs, and many Parties are currently implementing improved lighting practices by replacing incandescent light bulbs with compact fluorescent types.

The intention was understandable if everyone in the world exchanged most light bulbs for energy efficient compact fluorescent light bulbs (CFLs), we could save 3.5 of all electricity, or 1 of our CO2 emissions.
