Humidity can be measured in several ways, but relative humidity is the most common. In order to understand relative humidity, it is helpful to first understand absolute humidity. Absolute humidity is the mass of water vapor divided by the mass of dry air in a volume of air at a given temperature.
Malignant narcissism. Malignant narcissism is a psychological syndrome comprising an extreme mix of narcissism, antisocial personality disorder, aggression, and sadism. Often grandiose, and always ready to raise hostility levels, the malignant narcissist undermines organizations in which they are involved, and dehumanizes the people with whom they associate.
Malignancy (from Latin male, meaning 'badly', and -gnus, meaning 'born') is the tendency of a medical condition to become progressively worse. Malignancy is most familiar as a characterization of cancer. A malignant tumor contrasts with a non-cancerous benign tumor in that a malignancy is not self-limited in its growth, is capable of invading into adjacent tissues, and may be capable of spreading to distant tissues.
