Castleman disease must be distinguished from other disorders that can demonstrate Castleman-like lymph node features, including reactive lymph node hyperplasia, autoimmune disorders, and malignancies.
Relative humidity (abbreviated RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at the same temperature. Relative humidity depends on temperature and the pressure of the system of interest.
Absolute humidity is the water content of air at a given temperature expressed in gram per cubic metre.Relative humidity, expressed as a percent, measures the current absolute humidity relative to the maximum (highest point) for that temperature.bsolute humidity is the water content of air at a given temperature expressed in gram per cubic metre.
