XYZ Coheritor
A coherer or a coherer is a primitive type of bridge receiver on the telegraph.
The coherer was only fit for the reception of messages in the Morse Code.
For the reception of telephony without threads and of AM radio, this device was inadequate.
XYZ Construction and functioning
The coherent consists of a tenuous tube of glass with two electrodes, full, without pressure, of metal lime (FeNi). One side of the coherent is connected with the lantern, the other with the earth.
The high electric resistance includes an electric current from a source of energy connected parallel to the cohesor. But under the influence of a radio -unda, the dust is coherent, and the coherent allows for the easy passage of the current.
This run may, for example, ring a bell or control a relax. The cause of this effect is the crosshairs that are running between the sheets of metal and which make the pieces cloaked.
If it strikes at the bottom of the tube, it's the opposite, and it's the previous situation.
XYZ History
The coherer's invention is often attributed to French radiotelegraph pioneer Édouard Branly.
Around 1890, he used his radio conduit for the first time as a radio -unda receiver.
But the Italian physique Temistocle Calzecchi Onesti described the beginning of the six -year -old coherer. In his research he discovered that the electric conductiveness of the iron finish, confined to an insulated tube, grew heavily under the influence of outside electric fields.
Onesti used this mainly as a storm detector because it changed to atmosphere disturbs in the air.
The Englishman, then, explained the principles of his office, and gave it the name of the name of the name (coherer, coherer), based on the English word (to coherer). In more recent years, better disposals for the reception of radio -undas were developed, such as the receiver at the crack, the electronic tube and today's transistor.
XYZ Lingua creole haitian
The Native Greek language (kreyol ayasen), often referred to simply as Creolo, is a language spoken in Haiti by around eight million people (as of 2005).
That's almost all the population of the land.
In addition, there are about three hundred million Creophone emigrants in Canada, in the United States, in France, and in many expensive nations, especially in the Dominican Republic, Cuba, and the Bahamas.
The Haitian creole is one of the two official languages of Haiti, with the French.
It's a first -class creole in French, which comes to 90 percent of its vocabulary.
