There are two main categories of fish: oily and white. Oily fish is higher in. fat than white fish, but contains more. polyunsaturated fat which is a âgood fatâ. and a great source of omega 3 fatty acids. (see Understanding good and bad fats). White fish is low in fat, and high in protein. It also contains some omega 3 fatty acids, but not nearly as much as oily fish.
RR or R.R., 1. railroad. 2. Right Reverend. 3. rural route.
The RRR value is the ratio of the electrical resistivity at 4.2K to the electrical resistivity at 273K. This allows the thermal conductivity to be characterized, because there is a close correspondence between electrical and thermal conductivity in metals.
