A FAST FILE SYSTEM FOR UNIX

When the UNIX operating system was first introduced, the UNIX wizard himself Ken Thompson wrote the first file system. We will call that the “old UNIX file system”, and it was really simple. Basically, its data structures looked like this on the disk:

Ohmic heating is an alternative fast heating technique of foods. It is important to determine electrical conductivity in order to decide on the applicability of ohmic heating technology for specific food products. In this study, grape juice was heated at different voltage gradients 10, 20, 30 and 40[r]
