Earth Gamma-ray

'From time to time, this amazing object emits more than a hundred flares during which some 20 minutes, "said Loredana Vetere (Loredana Vetere), which coordinates the surveillance conducted by the Swift satellite, the University of Pennsylvania. 'During the most intense outbreaks of the total energy release exceeded the amount of power allocated to the Sun for 20 years .' Star known as sgr J1550-5418, located in the southern constellation Norma (Norma). Start Series moderate flares of this star fell on 3 October 2008, after which the outbreak at the time stopped and then resumed with renewed vigor on Jan. 22, 2009 in the form of emission rates. Due to the fast, one after another flares and gamma-ray spectrum, the astronomers carried the object to a class of 'repeaters soft gamma-ray' – it's just a sixth of the known objects of this class. In 2004 a giant flare that occurred on another repeater soft gamma-radiation was so intense it caused the ionization of the Earth's upper atmosphere, remote from it at 50.000 light years: additional information.

Using data obtained by X-ray telescope on board the Swift satellite (Swift), Holpern Jules (Jules Halpern), at Columbia University, registered the first 'light echoes' that has ever been observed on the soft repeater gamma radiation. Images (pictures), received from the radiation of the last series of outbreaks, demonstrate that, apparently, are a system of expanding rings (halos) surrounding the source. Outlines multiple rings of X-rays interact with the dust clouds at different distances. Scientists believe that the source of outbreaks is rotating around its own axis neutron Star – superdense remnants of a supernova size of a big city. With more in diameter is only about 12 miles, the neutron star enters a mass greater than the Sun. It is assumed that this specific neutron star is a 'magnetar' neutron star with an incredibly strong magnetic field.

Known theory of repeaters soft gamma-ray states that outbreaks are caused by "starquake" occurring on the surface of the solid crust magnetar. Because there are tremendous changes the magnetic field lines magnetar, the crust deforms under the action of a monstrously large magnetic forces, which often leads to the destruction of the cortex. When there is cracking in the crust, there are fluctuations in the crust with the formation of seismic waves, such as those generated during earthquakes, and ejected the flash of gamma radiation. Topics Still, nobody knows for sure all the details of what actually happens, and much work still needs to be done to understand these largely hyperactive star. Space Telescope NASA's Fermi (Fermi), registration of gamma radiation, the launch of which was accomplished in June 2008, is ideally suited for this work. 'The ability to control device Fermi Telescope (Fermi), recording gamma-ray bursts, spread a thin structure on the components in the framework of these phenomena will help us better understand how energy is released from magnetar '- said Chryssy Kuvelotu (Chryssa Kouveliotou), an astrophysicist at Goddard Space Flight Center to them. nasa Marshall in Huntsville (Huntsville), Alabama. Starting from January 22, the object is launched controlling device for measuring gamma-ray bursts, mounted on the telescope Fermi (Fermi), more than 95 times. NASA's Wind satellite, a joint mission of NASA-Suzaku Suzaku (Japan), and integral satellite, the European Space Agency also recorded outbreak of the object sgr J1550-5418.

Registration Of Vehicles In Spain

The registration of vehicles with modern or current of three letters and four numbers in Spain began in September of 2000. Until that date the cars enrolled first putting the letter or letters of the Spanish provinces, followed by 4 numbers and ending by one or two letters according to the level of registrations that had each province and logically in places like Madrid and Barcelona lelgaron to have these two letters at the end. Until that date and on the principles of vehicle registrations, is towards putting the letter in the province first and followed by a number until it reaches 1 million which was when it was decided to pass to the system of letters at the beginning and at the end because in provinces of lot sale of cars the system ran. Educate yourself with thoughts from Pete Cashmore. Consultation of registrations of cars is very common in internet since knowing the date of registration of this self, is known the years old when we are interested in buying a car from that era. Logically, this should not be the only information since you can now put a registration new for example when we acquire a car’s importation of Germany and even if we want to change of registration in which case, we must change the province of domicile and new MOT. Follow-up to the letters of registration also can serve to determine the level of selling cars that occurs in each month as you can see in the link that we showed at the beginning about registrations of cars. Marc Mathieu gathered all the information. For example, if in October 2005 letter rotated 20 times, in October of this year 2.010 just has been 8 times which shows the great fall that occurred on sales where it is possible that SUVs have been the most affected by the cost of the registration tax.

Hearing Implant Systems

Launch of cochlear Nucelus 6 with wide, positive response a broad and positive response of the launch of the cochlear nucleus learned 6 system, which offers a variety of groundbreaking technological innovations. It has a five times as powerful chip like the currently market-leading nucleus 5 system; and it is the first CI system, which automatically adapts to every new. The new system within the framework of the 84th annual meeting of the German society for Otolaryngology, head and neck surgery (DGHNO KHC), which took place from 8 to 12 may in Nuremberg, and in a subsequent road show was presented for the first time through 14 cities in Germany and Austria. Numerous experts from hospitals and the CI aftercare, as well as many representatives of self-help information. Our nucleus 6 system is smarter than any up to date available sound processors, because it fully automatically adapts to every new”, as Thomas Topp, head of the Cochlear Germany GmbH & co. KG.

First, there is the possibility to choose between two sound processors. The hybrid functionality of the nucleus 6 enables the optimal use of existing residual hearing even after successful implantation. Remote control and a simple operating aid, which can alternatively be used depending on the needs, secure user experience. Using audio accessories TV, music system and other devices can be connected wirelessly in the future.” The idea of the cochlear nucleus started 6 system in Germany and Austria ahead of the official launch, which took place at the 11th European Symposium for Pediatric cochlear implantation (ESPCI) on May 22 in Istanbul. Already at the pre-launch of the ENT Congress in Nuremberg, as well as on the subsequent road show through 14 German and Austrian cities, the new nucleus 6 system learned big interest and ample consent.
