About half of those who have mononucleosis have enlargement of the spleen, usually 2 to 3 weeks after they are infected. The incubation periodâthe time it takes symptoms to appear after a person becomes infected with the virusâcan be 4 to 6 weeks.Symptoms of mononucleosis usually last for 1 to 4 weeks, but it might take as long as 2 months before you feel well enough to resume all of your normal activities.bout half of those who have mononucleosis have enlargement of the spleen, usually 2 to 3 weeks after they are infected.

hair analysis. chemical analysis of a hair sample to find possible evidence of exposure to a toxic substance. Molecules of lead compounds and other chemicals are absorbed and stored in hair shafts. Hair analysis is also used to determine possible causes of malnutrition.
Kinematic analysis is the process of measuring the kinematic quantities used to describe motion. In engineering, for instance, kinematic analysis may be used to find the range of movement for a given mechanism, and, working in reverse, kinematic synthesis designs a mechanism for a desired range of motion.inematic analysis is the process of measuring the kinematic quantities used to describe motion.
