Prex is a portable 32-bit embedded real-time microkernel operating system. The kernel is compact, under 25k bytes, and provides memory management, inter-process communication (messages and shared memory) and multithreading in the kernel, and leaves more application-specific features like a file system to be implemented. It is designed to have virtual memory and memory protection when available. It is currently pre-beta, but runs on x86 PCs and the Game Boy Advance.
It has a POSIX emulation layer.
Phosphatidylinositol 3,4,5-trisphosphate-dependent Rac exchanger 1 protein is a protein that in humans is encoded by the PREX1 gene.
The protein encoded by this gene acts as a guanine nucleotide exchange factor for the RHO family of small GTP-binding proteins (RACs). It has been shown to bind to and activate RAC1 by exchanging bound GDP for free GTP. The encoded protein, which is found mainly in the cytoplasm, is activated by phosphatidylinositol-3,4,5-trisphosphate and the beta-gamma subunits of heterotrimeric G proteins.
The protein has been implicated in the spread of melanoma skin cancer.
Everywhere poverty reigns on this ground
Struggles for existence are the daily round
Survival of the fittest is the order of the day
A little more time, the earning of the stray
No way, no way
Is that all you have to say?
Stand up, fight back,
So far and not further
This way is wrong,
It´s time for a new order
The little child, it´s hungry and it´s riled
Its mother gave it away at the first ray of this day
No way, no way
Is that all you have to say?
Stand up, fight back,
So far and not further
This way, is wrong,
It´s time for a new order
No way, no way
