    SOLAR CELLS
    January 18, 1994 - U.S. Department of Energy

    The U.S. Department of Energy announced production of solar panels giving nearly twice the efficiency of existing panels. Made by United Solar Systems of Troy, Mich., these amorphous silicon submodule (1 ft2) panels converted 10.2% of solar energy into electricity, as compared to 6% previously possible. This was possible by using new thin-film photovoltaic technology. The company has subsequently produced flexible solar shingles based on thin film photovoltaics that can permit the roofs of ordinary commercial and residential buildings to evolve from simply providing protection from the weather to becoming a source of much-needed electric power.

    FIRST U.S. X-RAY MACHINE EXHIBITION ???
    January 18, 1896 - New York City, U.S.A.

    An x-ray machine was not exhibited at Casino Chambers, New York City, though some sources state it was. The news of Wilhelm Röntgen's discovery of the astonishingly penetrating X-rays had only been revealed to the world earlier in the month. So, riding on the wave of that publicity, the Cabaret du Neant opened, charging 25 cents admission to see the “Parisian sensation.” What the audiences actually saw was only a theatrical illusion of an x-ray image using only magic lantern techniques and the Peppers Ghost effect. No actual x-ray equipment was used. However, just a few days earlier, the first X-ray photograph in the U.S. has been credited were taken by Dr. Henry Lewis Smith in Davidson, N.C., on 12 Jan 1896. He had acted very quickly, as Röntgen made his discovery on 8 Nov 1895, announced it on 1 Jan 1896, and the first newspaper report, in Austria, was on 5 Jan 1896.

As we all know, toothaches and any type of oral injury can be extremely painful and should be seen by a dentist immediately. Dental emergencies should be seen immediately by a dentist, day or night. These emergencies include broken teeth, teeth that have been knocked out, or teeth that have been forced out of the socket. With some emergencies, the cheeks, lips, or gums will have cuts or abrasions on them from where the teeth come out of the socket.

If you've had a tooth recently knocked out, the first thing you should do is look for that tooth. When you've found the tooth, gently scrub it to get rid of any dirt or debris. Once you have cleaned it, you should place it back in your mouth between the cheek and gums. Whatever you do, you should never try to put it back in the socket. If you can make it to the dentist in time, he may be able to put the tooth back in place.

If you've had a tooth come out of place, you can normally reposition it with your fingers. You shouldn't use a lot of force, simply because it could damage the tooth. You shouldn't force the tooth into place, rather try and jiggle it around. You can also use moist tissue to hold the tooth in place, until you can get to a dentist.

If you've got a fractured tooth, the treatment will all depend upon how bad the booth has been fractured. No matter how light the fracture may be, it is very important that you get to a dentist as soon as you can. Minor fractures aren't that bad, as they can normally be smoothed out using sandpaper. Sometimes, the tooth can also be restored with a composite. Either way, you'll need to make sure that you use extreme caution with the tooth for the next few days.

The more moderate fractures, normally include damage to the dentin, pulp, and even the enamel. These fractures can be nothing to worry about at times, yet painful with other cases. Providing the pulp hasn't been damaged, your dentist will be able to restore the full shape and function to the fractured tooth. In cases where pulp damage has occurred, the dentist may need to do a root canal or other type of serious surgery to repair the tooth.

Whenever you encounter a dental emergency, you shouldn't hesitate to contact a dentist immediately. Your dentist will be able to assist you, fix the problem, and stop the pain. Dental emergencies can happen at any time, so you should always the emergency number of a dentist who will be there at a moments notice. Tooth pain can be very excruciating – and you'll obviously want to get the problem fixed immediately.
