Abstract: Objective: Stress, psychological distress and fatigue are frequently co-morbid experiences, but the nature of any temporal and/or causal relationships is unclear. This study examined possible mediators and moderators of the stress/psychological distress â fatigue relationship in a non-clinical sample.bstract: Objective: Stress, psychological distress and fatigue are frequently co-morbid experiences, but the nature of any temporal and/or causal relationships is unclear.

One of the properties of quantities with exponents is that numbers with exponents can be added and subtracted only when they have the same base and exponent. Since all numbers in scientific notation have the same base (10), we need only worry about the exponents.
Samiha Z. Scientific notation is used to represent a very large amount or very small amount in shorter terms. To write the number 5,000,000,000,000,000,000,000 would take a lot of time and thus people, especially scientists, use scientific notation to shorten the number so it is faster and easier to read and write. So instead of writing 5,000,000,000,000,000,000,000 scientists would right : #5.0xx 10^21#.
