Change Windows 8.1 lock screen time out 60 sec [Solved]

Daca si voua vi se stinge monitorul dupa un min ...
Dupa ce am incercat mai multe chestii, gen :

"You are most likely under PC Settings -> Accounts. The easiest way is to just press the windows key -> type: "user accounts" -> Reset Security Policies, located on the upper left hand side of the window.
Also found under:
Control Panel -> User Accounts and Family Security -> User Accounts
If it is not located under there then I believe that no changes have been made that require a reset, or you may have a different issue at hand other than an application enabling a 1 minute auto-lock feature onto your window's user account."

For the lucky one ! this works !

BUT I don't have "Reset Security Policies" button or checkbox !

After few hours of backUp-ing Registry and try diffrent values, I fount this:
And yes !! is a Romanian !! ;)

the registry key and value below:


Attributes DWORD
1 = Hide "Console lock display off timeout"
2 = Show "Console lock display off timeout"

This is for showing that option in PowerOption > Display
But why this fix to work from first try ! ?? :)
so open Registry => Win + R , or cmd and type: regedit
1) Export (for backup)
2 Find : 7516b95f-f776-4464-8c53-06167f40cc99

or by hand find : >HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\8EC4B3A5-6868-48c2-BE75-4F3044BE88A7

ok this key has 3 sub-kyes as you can see in the secon picture.
In the picture DefaultPowerSchemeValues > begins with : Bc537fda
I modified the one from middle with value 450 from 60 :)
As you can see with red squares
I changed Attribute value to 2, but in the Power Option => Display => Consoloe lock , I got a string:
something like : @%SystemRoot%\system32\powrprof.dll,-60,seconds
I saw that string in ValueUnits filed, so I changed like this :
and now PowerOption works :

Control Panel > Power Options > select a Plan > Edit Plan Settings > Change advanced power settings

Here as I showed in the picture I wasn't able do modify the value because was a log string
After that, you can see, now I can modify value to 5 min and 10 min. !!
Have fun !

Nanomotors Steered Inside Living Human Cells For the First Time

pe scurt
Nanomotors have been studied in vitro more more than a decade now. The hope is that eventually, they could be used inside of human cells for biomedical research. This nanotechnology could revolutionize drug delivery and even perform surgery in order to increase quality of life in the least invasive way possible. The earliest models were nonfunctional in biological fluid due to their fuel source. A huge breakthrough came later when the nanomotors were able to be powered externally via acoustic waves. The nanomotors used inside the human cells for the latest study were controlled by the ultrasonic waves as well as magnets.

Freescale makes the world's smallest ARM controller chip even tinier ARM controller chip even tinier 1,6 mm x 2mm

Freescale makes the world's smallest ARM controller chip even tinier Freescale Kinetis KL03 microcontroller
Apparently, Freescale didn't think the diminutive Kinetis KL02 was tiny enough -- it just unveiled the KL03, the new world's smallest ARM microcontroller. At 1.6mm by 2mm, the Cortex-M0+ chip is 15 percent smaller than its ancestor. That's miniscule enough to comfortably fit inside the dimple of a golf ball, folks. Despite the shrunken profile, it's both easier to program and more energy-efficient. The size isn't just for bragging rights, of course. Freescale sees the KL03 helping out the internet of things, where a fraction of a millimeter can make a big difference. Companies can't start using the chip in earnest until it enters full production this June, but it may lead to very compact smart appliances and wearables once it arrives.
