Cardiac output (known as âQâ) is a measure of the amount of blood that is pumped out of the heart in one minute. âQâ specifically refers to the amount of blood pumped out of the left ventricle as this is the ventricle that supplies blood to the muscles and organs of the body.
Preload is defined as the actual stretch or tension on the ventricular myocardium prior to contraction (Totora & Gabowski 2002). The greater the preload on the myocardium (the larger the amount of blood that has filled the heart during diastole), the greater the contraction will be.
The 512 byte bootloader code is stored with the Master Boot Record (MBR) and is loaded by the Basic Input/Output System (BIOS) via Interrupt (INT) 0x19 at 0x0000:0x7c00h. This is a standard sequence in booting for almost all x86 PCs, except that in some PCs it can be loaded to 0x7c00:0x0000h.ootloader is a small program that is executed under boot up in 16-bit Real Mode. It is very small, in fact, it is only 512 bytes and it resides on the very first sector of a boot device. The bootloader is used to load more complex programs like an OS Kernel.
