Internet messenger now in Arabic
For communication , for business for research now a days its the fastest time to send messege . . on demand its now in various language.
Splendor Telecom, has recently launched Ahwar Messenger, the first all-in-one Internet solution designed to provide the Arab community with a perfect online experience.
For the first time ever, Arab speakers will be able to use their Internet messenger in their native language as Ahwar Messenger offers them a unique blend of services including: online chatting, international phone calls to fixed and mobile lines at low cost, video calls, and a number of powerful Internet applications for greater communication flexibility.
Conceived from advanced communication technology, Ahwar Messenger gives all Arab users the opportunity to keep in touch with family and friends in their own language, wherever they are, all over the world.
"Ahwar Messenger has been designed in Arabic in order to address the Arab community especially that all similar global programs focus on American and European countries disregarding the Arab region," said Omar Ounsi, General Manager of Splendor Telecom. "Ahwar Messenger proves the high ability of Arab enterprises to develop their technical knowledge and expertise while competing with internationally renowned companies; it combines the most advanced technology with the best prices and services."
He added: "The personal messenger has become a very important communication tool and is integrated in every personal computer which facilitates communication between subscribers".
"Whenever one wants to contact a fixed or mobile phone line anywhere in the world, Ahwar Messenger is the first to guarantee the best voice quality at the lowest price starting 2 cents per minute without any additional cost," confirmed Michael Mansour, Chief Operating Officer of Splendor Telecom.
Ahwar Messenger services operate through prepaid rechargeable cards, available at competitive prices throughout the region. Today, it is the most advanced Arabic communication technology in the world supported by Arabic or English technical assistance 24 hours 7 days a week.

Saturn's Largest Moon
BYU professor Jani Radebaugh stands in front of an image of Titan taken with the Cassini Visual and Infrared Mapping Spectrometer (VIMS) instrument. "Bright features generally correspond to features of high topography, such as the mountains seen by the Radar instrument, and dark materials generally correspond to large dune fields made of organic particles," Radebaugh explains. "Thus, the rocky highlands are interspersed among the sand 'seas,' similar to Earth's continents and oceans
Mountains Discovered On Titan, Saturn's Largest Moon
By analyzing images from NASA’s Cassini Radar instrument, a Brigham Young University professor helped discover and analyze mountains on Saturn’s largest moon, additional evidence that it has some of the most earthlike processes of any celestial body in the solar system.
According to the study, Titan’s mountains are most likely made of water ice and are relatively small in height, at most 2 km (1.25 mi) from base to peak. The consistently short height of Titan’s mountains provides evidence that they have been subject to similar amounts of erosion, that they are roughly the same age or that the materials are behaving in a way that prevents them from growing taller.
Planetary scientist Jani Radebaugh is lead author of the discovery paper in the December issue of the astronomy journal Icarus. The images retrieved by the Cassini Radar are the first images showing the details of Titan’s surface – previous spacecraft and telescopes could not pierce the haze and clouds surrounding the moon to the surface.
The discovery of mountains on Titan grew out of Radebaugh’s collaboration with a research team that recently found sand dunes and methane lakes on Titan. Radebaugh was a coauthor on the Science study that introduced Titan’s sand dunes in May 2006 as well as the Nature study that introduced Titan’s methane lakes in January 2007.
“Since this is the first time humans have been able to see through the haze to Titan’s surface, it was shocking to find these mountains, channels, dunes, and cryo-lava flows,” Radebaugh said. “We had to wait until we got all the way to Titan to see these landforms that are so similar to Earth.”
Upon receiving the images from NASA, Radebaugh, in collaboration with the Cassini Radar Team, discovered the mountains and began analyzing their characteristics. With no instrument to precisely measure the mountains’ height, Radebaugh looked at the light and shadows in the radar images to calculate the mountains’ slope and then derive their height.
“Dr. Radebaugh’s work represents an important advance in our understanding of that icy moon and the Earth,” said Dr. Jason Barnes, a research scientist at the NASA Ames Research Center. “Her discovery tells us about the mountain-building process in general and about Titan’s crust in particular.”
Prior to Cassini, scientists assumed that most of the topography on Titan would be impact structures, yet these new findings reveal that similar to Earth, the mountains were formed through geological processes on the moon.
Radebaugh proposes four possible explanations for the formation of the mountains on Titan. The first possibility is that the mountains were thrust up from crustal compression, horizontal forces smashing the crust together and upward. Alternatively, Titan’s mountains may have formed through spreading or separation of the crust, in the same way that Utah’s Wasatch Mountains separated from the Oquirrh Mountains to the west.
It’s also possible some of the mountains have been created by impact craters that threw out blocks of material, or that erosion stripped away a preexisting layer of material and left high-standing features like the mountains.
Since the processes on Titan are so similar to Earth’s, Radebaugh also concluded in the study that Titan may be an interesting laboratory for studying Earth. Like Earth, Titan possesses the primary ingredients for life, namely energy, water and organics. Information from Titan will help scientists better understand the Earth’s origin, formative processes and development of life.
“We still don’t understand exactly how life began on Earth, so if we can understand how the fundamentals of these processes may be starting in some laboratory like Titan, it will help us understand the Earth a lot better,” Radebaugh said.
In addition to analyzing images from space, Radebaugh also looks on planet earth for clues about the geology of other planets, moons and objects in the solar system. Two years ago Radebaugh scoured Antarctica for meteorites with the Antarctic Search for Meteorites (ANSMET) program. Through field work at Hawaiian volcanoes, she has also worked with students to utilize a technique for using a camcorder to measure eruption temperatures in the hope of learning more about volcanoes on Io, a moon of Jupiter.
