Urodynamic testing or urodynamics is a study that assesses how the bladder and urethra are performing their job of storing and releasing urine. Urodynamic tests can help explain symptoms such as:
Some mixtures give rise to the reddish and purplish fall colors of trees such as dogwoods and sumacs, while others give the sugar maple its brilliant orange. The autumn foliage of some trees show only yellow colors. Others, like many oaks, display mostly browns. All these colors are due to the mixing of varying amounts of the chlorophyll residue and other pigments in the leaf during the fall season.
Brilliant colors are more often seen when the fall weather has warm, sunny days with cool nights between 32Â° and 45 Â°F. Indeed, shade-grown leaves often are a duller color than leaves that are in the full sun, even on the same plant. The reds and purples found during the fall are due to the anthocyanin compounds.
