But the strain that emerged in California (a «1 H. The 1» different

Very strain of influenza virus (H 1, 1), which affects the rights,

And in the seasonal influenza vaccine.

It is also not yet known whether the infection

Influenza type «AH-1 that 1» the human (human type A H1N1

flu) provide protection (immunity) against the partial swine influenza virus

Type «The 1 H er 1» (type A H1N1 swine flu) in the light of the epidemic

The current world.

However, has the U.S. Centers for Disease Control drawing

The virus from an infected person or an origin of the seed production of a new vaccine

Against this virus.

And the production of the vaccine will take between four to six months, but remains

The great question about the possibility of production of this vaccine plentiful

Information about the Moon

Moon
Inspiring poets and a symbol of beauty
Requires us to pause and find some information about
It is one of the brothers are interested in astronomy Thales was the subject you
Moon

Moon is similar to the planets in many respects, with a capacity of 3485 km This alone is enough as it stands in the list of planets, the moon bigger than Pluto, which is slightly smaller than Mercury, but the moon revolves around the earth around the sun, not like the rest of the planets
So the moon is a planet Earth and not only in the case of changing the definition of what the planet
The moon is oval Bmadar from west to east - as the organization - once a month - every 29 days and 12 hours and 44 minutes and 28 seconds - as if a rope is tied to the Earth's gravity is an invisible, which can not escape.
Dark which is a crime in itself, but Nora is derived from the reflection of sunlight reflected back to Earth cycle
The average distance between the Moon and the Earth is equivalent to 384 thousand kilometers, but it is at an apogee of about 405 thousand kilometers, and had a minimum of about 355 thousand kilometers. Surface area of up to 7.5% of the melancholy earth, and that means that the area of the Moon is almost equal to that of a U.S. North and South
The size of the moon is smaller than the size of the Earth by 50 times, and a mass of less than 82 times the mass of the earth.
The force of gravity on the moon less than 6 times the force of gravity on the ground, it was on the ground and weighed 60 kg, Vosenh on the moon only 10 kg, speed around the Earth at 3700 km.
On the other hand it is remarkable to consider is that the orange color of the moon at the horizon
Due to the scattering of light by the atmosphere, when the moon is near the horizon is the light of the moon's surface vertically above the ground.
During the period when the moon light up the eyes, most of the short-wave visible light (green, blue, violet) is littered with the effect of dispersed particles from the air. Based on the foregoing, we receive only the long-wave (yellow, orange, red)
Sometimes the moon appears orange color of his Balram docked above ground because in this case the presence of a large quantity of pollutants and smoke and dust in the atmosphere / The size of these particles, which we see the type of color of the moon, the moon as it seems in these cases, red or orange or blue .
Temperatures on the Moon, ranging from warm and cold, Vaz was able to build a human colony on the moon in the future goals of the astronaut can be there as much as boiling water with a temperature of the sun when it is docked on the surface of the Moon to 100 degrees Celsius and at night the temperature drop to - 173 degrees Celsius.
The reason for this discrepancy in the temperature of the free atmosphere of the moon, who works on the absorption of high energy to the sun, as in the hemisphere, the moon and the absence of atmospheric Net helps to heat the surface such as x-ray helps to escape the heat during the night of the moon. Enlightening the surface of the moon, which is called the lunar-day Yalnhar 14 days ago, when the moon is being unfair to the so-called lunar night, which lasts approximately 14 Som.
It is not the moon's atmosphere protects the surface from the sun or the temperature is maintained, not as in water vapor, so the life of him, and has the ability to reverse a weak Moon Ieki 7% of the sunlight which Itlqaah and Ssdr Hrar weak in the case of the full moon.
The ratio between the blocs of the earth and the moon are much greater between the ratio of any other planet and moon, it's the exception to the offense, which revolves around Charone dwarf Pluto.
Moon has been studied since ancient times on the way to enable the example of the Babylonians and the Maya provide accurate assessment of the eclipse and the eclipse and other astronomical phenomena.
Astronomers now know the different kinds of months, such as Alaguetrani month (lunar month) and the amount of 29 days and 12 hours and 44 minutes, a period of aspects of the moon, the month and the amount of interstellar U-27 and 7 hours and 43 minutes, the length of the rotation of the Moon around the Earth.
