Q: An antenna (plural antennae or antennas), or aerial, is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter supplies an electric current oscillating at radio frequency (i.e. a high frequency alternating current (AC)) to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals, that is applied to a receiver to be amplified.

Typically an antenna consists of an arrangement of metallic conductors (elements), electrically connected (often through a transmission line) to the receiver or transmitter. An oscillating current of electrons forced through the antenna by a transmitter will create an oscillating magnetic field around the antenna elements, while the charge of the electrons also creates an oscillating electric field along the elements. These time-varying fields radiate away from the antenna into space as a moving transverse electromagnetic field wave. Conversely, during reception, the oscillating electric and magnetic fields of an incoming radio wave exert force on the electrons in the antenna elements, causing them to move back and forth, creating oscillating currents in the antenna.

RAISING THE TENT

Toby went into the house, feeling rather uneasy because he had not been called; but when Aunt Olive told him that Abner had aroused from his slumber but twice, and then only for a moment, he had no idea of being worried about his friend, although he did think it a little singular he should sleep so long.

That evening Dr. Abbot called again, although he had been there once before that day; and when Toby saw how troubled Uncle Daniel and Aunt Olive looked after he had gone, he asked;

"You don't think Abner is goin' to be sick, do you?"

Uncle Daniel made no reply, and Aunt Olive did not speak for some moments; then she said:

"I am afraid he stayed out too long this morning; but the doctor hopes he will be better to-morrow."

If Toby had not been so busily engaged planning for Abner to see the work next day, he would have noticed that the sick boy was not left alone for more than a few moments at a time, and that both Uncle Daniel and Aunt Olive seemed to have agreed not to say anything discouraging to him regarding his friend's illness.

When he went to bed that night, he fancied Uncle Daniel's voice trembled, as he said:

"May the good God guard and spare you to me, Toby, boy;" but he gave no particular thought to the matter, and the sandman threw dust in his eyes very soon after his head was on the pillow. 1. Which doctor came over?

Washington (CNN) -- The Obama administration appealed Friday to the U.S. Supreme Court to delay next week's scheduled execution in Texas of a Mexican national convicted of kidnapping, raping and murdering a 16-year-old girl.

The execution of Humberto Leal Garcia, who was sentenced to death for the 1994 crimes, "would place the United States in irreparable breach of its international-law obligation to afford (Leal) review and reconsideration of his claim that his conviction and sentence were prejudiced by Texas authorities' failure to provide consular notification and assistance under the Vienna Convention on Consular Relations," wrote Solicitor General Donald B. Verrilli Jr., in a friend-of-the-court brief.

In a separate document, a letter to Texas Governor Rick Perry, the U.N. High Commissioner for Human Rights asked that he commute the sentence to life in prison, according to Rupert Colville, a spokesman for Navi Pillay.

The two requests were based on the failure of Texas authorities to grant the 38-year-old Leal -- who has lived in the United States since he was 2 years old -- access to a Mexican consular official at the time of his arrest.

"The lack of consular assistance and advice raises concerns about whether or not Mr. Leal Garcia's right to a fair trial was fully upheld," Colville said.

The case "raises questions" regarding compliance with a 2004 International Court of Justice ruling in what is known as the Avena case that the United States failed to fulfill its obligations to 51 Mexicans on death row in U.S. jails when it did not inform them of their right to contact their consular representatives "without delay" after their arrests, he said. What are the answers to this following set of questions: 1. who was the un letter to?
2. what's his job
3. What does Rick Perry do?
4. of?
