Mobile Phones

This subject talks about definition, advantages and disadvantages of mobile phones. Mobile phone is a hand held device with built-in antennas often called cell phone. Mobile phones are seen as a modern invention, but they are a development of something that dates back a long way.

The biggest and most obvious change is the rapid take-up of mobile phones. Twelve years ago, they were only for the wealthy, and had a "yuppie" image. Seven years ago they were still rare. Now there are more mobile phones than households and numbers are still growing fast. We are approaching the time when it will be considered unusual not to have a mobile phone.
There are many advantages of mobiles. They are convenient to use i.e. using it anytime you need to make a call, SMS can be used when one can’t afford to call, enables one to send and receive e-mail, They are portable e.g. it can be carried from one place to another.
But the disadvantages are that children’s skulls are vulnerable to radio waves from phones which can damage their brain tissues as the nervous system is very sensitive during development. Cell phone antennas which are close to earpiece are harmful to humans due to large volumes of electro-magnetic waves that get concentrated around it during the receipt and placing of calls. Vibrating phones affect men’s reproductive system, radiation from phones also increase blood-pressure, risk of brain tumors mainly acoustic neuromas. Lab research also shows that long exposure to mobile phone on stand-by leads to serious degradation of white blood cells. They are susceptible to loss and theft. Restricting access to corporate data and applications. Non-repairable internal corrosion of parts if wet.

Vulnerable to extreme heat or cold which may cause momentary loss of screen display. Mobiles are very noisy sometimes especially when we are praying in the mosque, learning at university, or reading in libraries.

The History of the Telephone – Alexander Graham Bell

In the 1870s, two inventors Elisha Gray and Alexander Graham Bell both independently designed devices that could transmit speech electrically (the telephone). Both men rushed their respective designs to the patent office within hours of each other, Alexander Graham Bell patented his telephone first. Elisha Gray and Alexander Graham Bell entered into a famous legal battle over the invention of the telephone, which Bell won.

Alexander Graham Bell – Evolution of the Telegraph into the Telephone
The telegraph and telephone are both wire-****d electrical systems, and Alexander Graham Bell’s success with the telephone came as a direct result of his attempts to improve the telegraph.

When Bell began experimenting with electrical signals, the telegraph had been an established means of communication for some 30 years. Although a highly successful system, the telegraph, with its dot-and-dash Morse code, was basically limited to receiving and sending one message at a time. Bell’s extensive knowledge of the nature of sound and his understanding of music enabled him to conjecture the possibility of transmitting multiple messages over the same wire at the same time. Although the idea of a multiple telegraph had been in existence for some time, Bell offered his own musical or harmonic approach as a possible practical solution. His "harmonic telegraph" was ****d on the principle that several notes could be sent simultaneously along the same wire if the notes or signals differed in pitch.

Alexander Graham Bell – Talk with Electricity
By October 1874, Bell’s research had progressed to the extent that he could inform his future father-in-law, Boston attorney Gardiner Greene Hubbard, about the possibility of a multiple telegraph. Hubbard, who resented the absolute control then exerted by the Western Union Telegraph Company, instantly saw the potential for breaking such a monopoly and gave Bell the financial backing he needed. Bell proceeded with his work on the multiple telegraph, but he did not tell Hubbard that he and Thomas Watson, a young electrician whose services he had enlisted, were also exploring an idea that had occurred to him that summer – that of developing a device that would transmit speech electrically.

While Alexander Graham Bell and Thomas Watson worked on the harmonic telegraph at the insistent urging of Hubbard and other backers, Bell nonetheless met in March 1875 with Joseph Henry, the respected director of the Smithsonian Institution, who listened to Bell’s ideas for a telephone and offered encouraging words. Spurred on by Henry’s positive opinion, Bell and Watson continued their work. By June 1875 the goal of creating a device that would transmit speech electrically was about to be realized. They had proven that different tones would vary the strength of an electric current in a wire. To achieve success they therefore needed only to build a working transmitter with a membrane capable of varying electronic currents and a receiver that would reproduce these variations in audible frequencies.

First Sounds – Twang
On June 2, 1875, Alexander Graham Bell while experimenting with his technique called "harmonic telegraph" discovered he could hear sound over a wire. The sound was that of a twanging clock spring.

Bell’s greatest success was achieved on March 10, 1876, marked not only the birth of the telephone but the death of the multiple telegraph as well. The communications potential contained in his demonstration of being able to "talk with electricity" far outweighed anything that simply increasing the capability of a dot-and-dash system could imply.

First Voice – Mr. Watson, come here. I want to see you.
Alexander Graham Bell’s notebook entry of 10 March 1876 describes his successful experiment with the telephone. Speaking through the instrument to his assistant, Thomas A. Watson, in the next room, Bell utters these famous first words, "Mr. Watson — come here — I want to see you."

Alexander Graham Bell – Brief Biography
Born on March 3, 1847, in Edinburgh, Scotland, Alexander Graham Bell was the son and grandson of authorities in elocution and the correction of speech. Educated to pursue a career in the same specialty, his knowledge of the nature of sound led him not only to teach the deaf, but also to invent the telephone.

Who Really Invented the Telephone?

Well, that may depend on your ethnic heritage or the country you live in to some degree. Because it is possible for more than one person to come up with the same idea in roughly the same moment in time, there could have been more than one inventor of the telephone.
Although Alexander Graham Bell is considered the inventor of the telephone in the USA, Canada, and Scotland, other countries that had no historical affiliation with him tend to look for possible inventors of their own ethnic background or their own country as THE inventor of the telephone. Several web sites address this never-ending debate and it is doubtful that there is any way of proving who really came up with the idea and put it into practice first. Even here in the USA, many court battles were fought between Bell and several challengers to his right to be called the inventor of the telephone.
At the end of this page are some links to external web sites that discuss some of these other contenders. But first, read the following section from a book titled "The History of the Telephone" BY HERBERT N. CASSON – First edition – A. C. McClurg & Co., Chicago – Published: 1910. The following paragraphs from the book give an account of some of the court battles that Bell went through in defending his claim as the inventor of the telephone:
"After Gray, the weightiest challenger who came against Bell was Professor Amos E. Dolbear, of Tufts College. He, like Gray, had written a letter of applause to Bell in 1877. "I congratulate you, sir," he said, "upon your very great invention, and I hope to see it supplant all forms of existing telegraphs, and that you will be successful in obtaining the wealth and honor which is your due." But one year later, Dolbear came to view with an opposition telephone. It was not an imitation of Bell’s, he insisted, but an improvement upon an electrical device made by a German named Philip Reis, in 1861.
Thus there appeared upon the scene the so-called "Reis telephone," which was not a telephone at all, in any practical sense, but which served well enough for nine years or more as a weapon to use against the Bell patents. Poor Philip Reis himself, the son of a baker in Frankfort, Germany, had hoped to make a telephone, but he had failed. His machine was operated by a "make-and-break" current, and so could not carry the infinitely delicate vibrations made by the human voice. It could transmit the pitch of a sound, but not the QUALITY. At its best, it could carry a tune, but never at any time a spoken sentence. Reis, in his later years, realized that his machine could never be used for the transmission of conversation; and in a letter to a friend he tells of a code of signals that he has invented.
Bell had once, during his three years of experimenting, made a Reis machine, although at that time he had not seen one. But he soon threw it aside, as of no practical value. As a teacher of acoustics, Bell knew that the one indispensable requirement of a telephone is that it shall transmit the WHOLE of a sound, and not merely the pitch of it. Such scientists as Lord Kelvin, Joseph Henry, and Edison had seen the little Reis instrument years before Bell invented the telephone; but they regarded it as a mere musical toy. It was "not in any sense a speaking telephone," said Lord Kelvin. And Edison, when trying to put the Reis machine in the most favorable light, admitted humorously that when he used a Reis transmitter he generally "knew what was coming; and knowing what was coming, even a Reis transmitter, pure and simple, reproduces sounds which seem almost like that which was being transmitted; but when the man at the other end did not know what was coming, it was very seldom that any word was recognized."
In the course of the Dolbear lawsuit, a Reis machine was brought into court, and created much amusement. It was able to squeak, but not to speak. Experts and professors wrestled with it in vain. It refused to transmit one intelligible sentence. "It CAN speak, but it WON’T," explained one of Dolbear’s lawyers. It is now generally known that while a Reis machine, when clogged and out of order, would transmit a word or two in an imperfect way, it was built on wrong lines. It was no more a telephone than a wagon is a sleigh, even though it is possible to chain the wheels and make them slide for a foot or two. Said Judge Lowell, in rendering his famous decision:
"A century of Reis would never have produced a speaking telephone by mere improvement of construction. It was left for Bell to discover that the failure was due not to workmanship but to the principle which was adopted as the basis of what had to be done. . . . Bell discovered a new art–that of transmitting speech by electricity, and his claim is not as broad as his invention. . . . To follow Reis is to fail; but to follow Bell is to succeed."
After the victory over Dolbear, the Bell stock went soaring skywards; and the higher it went, the greater were the number of infringers and blowers of stock bubbles. To bait the Bell Company became almost a national sport. Any sort of claimant, with any sort of wild tale of prior invention, could find a speculator to support him. On they came, a motley array, "some in rags, some on nags, and some in velvet gowns." One of them claimed to have done wonders with an iron hoop and a file in 1867; a second had a marvelous table with glass legs; a third swore that he had made a telephone in 1860, but did not know what it was until he saw Bell’s patent; and a fourth told a vivid story of having heard a bullfrog croak via a telegraph wire which was strung into a certain cellar in Racine, in 1851.
This comic opera phase came to a head in the famous Drawbaugh case, which lasted for nearly four years, and filled ten thousand pages with its evidence. Having failed on Reis, the German, the opponents of Bell now brought forward an American inventor named Daniel Drawbaugh, and opened up a noisy newspaper campaign. To secure public sympathy for Drawbaugh, it was said that he had invented a complete telephone and switchboard before 1876, but was in such "utter and abject poverty" that he could not get himself a patent. Five hundred witnesses were examined; and such a general turmoil was aroused that the Bell lawyers were compelled to take the attack seriously, and to fight back with every pound of ammunition they possessed.
The fact about Drawbaugh is that he was a mechanic in a country village near Harrisburg, Pennsylvania. He was ingenious but not inventive; and loved to display his mechanical skill before the farmers and villagers. He was a subscriber to The Scientific American; and it had become the fixed habit of his life to copy other people’s inventions and exhibit them as his own. He was a trailer of inventors. More than forty instances of this imitative habit were shown at the trial, and he was severely scored by the judge, who accused him of "deliberately falsifying the facts." His ruling passion of imitation, apparently, was not diminished by the loss of his telephone claims, as he came to public view again in 1903 as a trailer of Marconi.
Drawbaugh’s defeat sent the Bell stock up once more, and brought on a Xerxes’ army of opposition which called itself the "Overland Company." Having learned that no one claimant could beat Bell in the courts, this company massed the losers together and came forward with a scrap-basket full of patents. Several powerful capitalists undertook to pay the expenses of this adventure. Wires were strung; stock was sold; and the enterprise looked for a time so genuine that when the Bell lawyers asked for an injunction against it, they were refused. This was as hard a blow as the Bell people received in their eleven years of litigation; and the Bell stock tumbled thirty-five points in a few days. Infringing companies sprang up like gourds in the night. And all went merrily with the promoters until the Overland Company was thrown out of court, as having no evidence, except "the refuse and dregs of former cases-the heel-taps found in the glasses at the end of the frolic."
But even after this defeat for the claimants, the frolic was not wholly ended. They next planned to get through politics what they could not get through law; they induced the Government to bring suit for the annulment of the Bell patents. It was a bold and desperate move, and enabled the promoters of paper companies to sell stock for several years longer. The whole dispute was re-opened, from Gray to Drawbaugh. Every battle was re-fought; and in the end, of course, the Government officials learned that they were being used to pull telephone chestnuts out of the fire. The case was allowed to die a natural death, and was informally dropped in 1896.
In all, the Bell Company fought out thirteen lawsuits that were of national interest, and five that were carried to the Supreme Court in Washington. It fought out five hundred and eighty-seven other lawsuits of various natures; and with the exception of two trivial contract suits, IT NEVER LOST A CASE."

Specialized study warned that the growing premature aging among young people by the use of the mobile phone, pointing out that the electromagnetic waves emanating from radio towers and wireless telephone help on the activity of breast cancer and its spread.

Has revealed the scientific study – prepared by the research team headed by Professor of Biophysics and Medical Radiation b b Faculty of Science, Cairo University, Dr. Fadel Muhammad as Al-Arab Online, revealed that the introduction of modern equipment and technology deployment in everyday life have adverse biological effects on human health.

The study, the short-wave which man is exposed within the home or at work lead to the obvious damage in the wall cells, especially red blood cells, and also cause an imbalance in blood enzymes, a result of the injury to the cells of glands that secrete these enzymes.

The study said, it was observed that there are adverse effects on the enzymes of the liver and various glands, muscles, and the focus of some hormones, including testosterone, as well as electric, heart and bone marrow and its inability to produce healthy blood, pointing to the impact on mice embryos in the mother’s abdomen and her leukemia and lymphoma.

The other hand, has warned a scientific study from previous exposure to magnetic fields generated by modern devices, including mobile phone, to a negative impact on human health, especially for girls and pregnant women because of the biological effects caused by the breast and the baby.

The study, conducted by the newly Basic Sciences Research Council, Academy of Scientific Research and Technology in Egypt, that exposure to magnetic waves used in broadcasting and communication processes through mobile phone lead to the obvious damage in the wall cells, especially blood cells.

As well as to an imbalance in the blood enzymes as they cause in the incidence of breast cancer in women, noting that such damage vary depending on the density which is exposure. She explained that the scientific experiments demonstrated that exposure to short-wave and portable, a band of medium or low frequencies from radio broadcasting, resulting in injury to the fetus in his mother’s womb cancer, blood and lymph nodes also leads to cessation of activity of lymph glands and is responsible for the secretion of milk of the mother.

This is part of another, we all know that eating fresh vegetables and soy products a healthy diet is more than eating junk food. Even though everyone understood this fact, but few women keep it. This led doctors to believe that this is possible to be one of the reasons that cause breast cancer.

Studies indicated in the past that American women were Asian and the Middle less affected than other races of breast cancer, because Hamithn food but the statistics are pointing to a rise in this ratio with changing dietary habits in those areas.

The relationship became a close relationship between dietary habits and practice between the high incidence of cancer. In the latest statistics show that food accounted for 30% of the causes of cancer.

It is advisable for doctors to return to the kitchen because its East Asian component of fresh vegetables and fruits, which have proved to have the biggest impact in fighting cancer and many other diseases that took the widespread diffusion of the age.

Among the tips be replaced with meat, eggs, fish three times a week at least, as well as a national to add little of soy milk to your food since it had a significant impact in fighting cancer.

Also, green tea very helpful in fighting cancer and helps in purifying the blood in addition to being of those who burn more calories in your body.

Here are more tips for the prevention of breast cancer ..

– Marcy exercise three times a week for at least 45 minutes each time, not matter what kind of sport, but it is important to be doing the revitalization of your body.

– Eat plenty of vegetables, especially leafy full of fiber such as broccoli and kale and spinach.

– A national buying a machine for the preparation of fresh juice and fresh juice to address a national daily. And nationalist era all kinds of vegetables and fruits, without exception, such as carrots with apple and parsley, kale and spinach with apple, or lemon with garlic.

– Avoid wearing underwear that narrow harass your chest.

– Avoid foods rich in fat.

– Eat foods derived from soy such as tofu, and soy beans and soy milk.

– Try to reduce your consumption of cheese and all dairy products.

– Try a simple meditation for every day and inhalation of a national clean air and take it out slowly, and try to dig deeper in the arts of meditation such as yoga.

– Please see a specialist doctor to conduct periodic examinations annually.

– Loose chest periodically to make sure there are no lumps or blocks are not natural.

– Try to maintain your weight within normal limits, and if he was overweight, try to follow a diet to gain access to your normal levels.

– Eat a green tea as you can and try to reduce your consumption of caffeine daily.

– Try not to Tkpti any feelings you feel it, So try to always vent your anger and anxiety and your fears.

– Eat a 800 mg daily of vitamin (e) and 1000 mg of vitamin (c) a day.

And specifically on the tension and its relationship to breast cancer, researchers have said that the Swedes stress can double the risk of women with breast cancer. The researchers based their findings on surveys of more than 1400 women Sweden Be part of the health study and wide.

The request of the women and who were described as representing a sample of all segments of the Swedish society to mobilize health model includes questions about the tension and if you have experienced by women during the past five years, a state of tension for a month or more.

Include situations of tension that can be witnessed by women fear, anxiety, or sleep disorders because of family problems or problems at work
