Descubren el origen de los reflejos en la superficie de Titán ...

Las zonas brillantes observadas en las regiones tropicales meridionales del mayor satélite de Saturno, Titán, son probablemente los lechos de lagos y mares de hidrocarburos secos, revela una reciente investigación publicada este martes en la revista Nature.
Entre los años 2000 y 2008, los radiotelescopios del Observatorio de Arecibo en Puerto Rico y el Observatorio de Green Bank en Virginia Occidental (EE.UU.) detectaron cerca de una docena de regiones anómalamente brillantes en la segunda luna más grande del sistema solar. 

Cuando la nave espacial Cassini de la NASA llegó a Saturno en el 2004, detectó más de 500 lagos y mares, pero solo cerca de los polos de Titán, y demostró que esa luna tiene un sistema climático activo: el metano y el etano, en lugar del agua, caen del cielo en forma de lluvia, bajan por los sistemas fluviales y se acumulan en estanques.

Sin embargo, las regiones tropicales meridionales, donde aparecieron los reflejos, resultaron ser extremadamente secas, por lo que los investigadores decidieron examinar todos los datos recopilados durante los últimos 20 años. Tras utilizar las observaciones de Cassini para "verificar sobre el terreno" la información reunida por los observatorios, se dieron cuenta de que todos los brillos registrados provienen de puntos específicos, que se parecen a otras cuencas lacustres vacías ubicadas cerca de los polos.

HTML5 Games On Android

Par
On my last hollidays, I made two HTML5 games, and published on android market. Nowadays javascript has powerful libraries for doing almost everything, and also there are several compilers from java or c code to javascript, converting opengl c code to html5 canvas, but definitely, javascript execution is slower than dalvik applications, and of course much slower than arm c libs. For improving the speed of sounds and images loader, I have used javascript asynchronous execution and scheduling priority has been controlled with setTimeout/setInterval which deprioritize or priorize a code block. This games are published on the android market here: Android Planets and here: Far Planet Related news Hacker Hardware Tools Pentest Tools Port Scanner Hacker Tools For Mac Tools Used For Hacking Hacker Techniques Tools And Incident Handling Easy Hack Tools Hacking Tools Kit Hacking Tools Usb Hacker Hardware Tools Hacker Tools Hardware Hack Tools For Windows Hacking Tools For G...

History  The patient's past medical history was significant for attention-deficit hyperactivity disorder. He admitted to using tobacco and alcohol socially, but denied illicit drug use. He denied any medication use or drug allergies. A review of systems was positive for complaints of abdominal pain and anxiety. Physical examination  The patient's vital signs were: BP, 112/51 mm Hg; heart rate, 110 beats/minute; respirations, 23; SpO 2 , 95% on room air; and temperature, 37.4° C (99.3° F). On ED arrival, he was awake, alert, and oriented but appeared anxious and agitated. His pupils were equal, round, and reactive to light.
