Zen stone update

Oh, we're talking about Creative's Zen Stone Plus, naturally. Those crazy Yanks are busy scoffing all the leftover turkey and cold pumpkin pie they can lay their hands on today, but we don't care about Thanksgiving here in the U of K, so instead we're giving thanks to Creative. Because it's just let a whopping great news story rip: there's a 4GB Zen Stone Plus on the horizon, and it's got a Thanksgiving feast of improvements over the original version.

Music files that use other forms of copy protection cannot be transferred to or be played on your player. Some content from online music stores may not be transferable to portable devices, or there may be a limit on the number of transfers. For details, contact your online music store. The file transfer process may have been interrupted.

To safely disconnect your player after transferring files, click the Disconnect Player button in Creative Media Lite or click the Safely Remove Hardware icon on the Taskbar. To transfer music to your player, you can use Creative Media Lite. Other software may not. Your player supports up to three folder levels from the root.

Your player has a limit of folders. Your player supports up to playable tracks, depending on your player's capacity and individual song quality. Your player's playback sequence follows the alphanumeric order of the file names. To customize playback sequence, add a number in front of the file name for example, 01 Track A, 02 Track B, and so on.

The track may have been transferred incorrectly or is in an unsupported format. Check the following: The track is in a format supported by your player. The track is within three levels of folders from the root. If the music track is copy protected, make sure that it is transferred using Creative Media Lite, not Windows Explorer. It does not support PlaysForSure and subscription content. Audible content refers to spoken audio programs such as audio books that you can purchase online.

To transfer Audible content to your player, download AudibleManager at www. To skip sections within an Audible track Using your player's mode switch, push and hold at Skip Folder.

Release the mode switch when the LED starts blinking slowly. If no button is pressed for a few minutes, your player returns to normal play mode. This can be downloaded from the Creative web site, www. The battery may be too depleted to power your player. Charge the player for approximately two to three hours by connecting the USB cable to an actively running computer before turning on the player again.

Avoid using a USB hub. If you encounter problems after two to three hours, try the following: Do not use a USB hub and ensure that the USB cable is connected properly. Connect your player to another computer Reset your player.

Charles Darwin described penitentes in after a March excursion in which he squeezed his way through snowfields covered in penitentes on the way from Santiago, Chile, to the Argentine city of Mendoza. Physicists have been able to recreate artificial versions of penitentes in the lab. But penitentes and stone forests are actually quite different in terms of the mechanisms involved in their formation. The spikes of a stone forest are carved by flows, which don't play a big role in the formation of penitentes.

Some physicists have suggested that penitentes form when sunlight evaporates the snow directly into vapor sublimation. Tiny crests and troughs form, and sunlight gets trapped within them, creating extra heat that carves out even deeper troughs, and those curved surfaces in turn act as a lens, speeding up the sublimation process even more.

An alternative proposal adds an additional mechanism to account for the oddly periodic fixed spacing of penitentes: a combination of vapor diffusion and heat transport that produces a steep temperature gradient and, hence, a higher sublimation rate.

Earlier this month, they published a somewhat related study in Physical Review Letters on the natural formation of glacier tables a rock supported by a slender column of ice. They were able to produce small-scale artificial glacier tables in a controlled environment and found two competing effects that control the onset of glacier table formation. With smaller stone caps with higher thermal conductivity, geometrical amplification of the heat flux causes the cap to sink into the ice.

For a larger cap with less thermal conductivity, a reduction in heat flux arises from the fact that the cap has a higher temperature than the surrounding ice, forming a table. For this latest study, Taberlet and Plihon wanted to explore the underlying mechanisms behind the natural formation of Baikal Zen structures.

So the researchers set about trying to reproduce the phenomenon in the laboratory to test their hypothesis.
