Addiction is a chronic brain disorder and not simply a behavior problem involving alcohol, drugs, gambling or sex, experts contend in a new definition of addiction, one that is not solely related to problematic substance abuse.he disease creates distortions in thinking, feelings and perceptions, which drive people to behave in ways that are not understandable to others around them, Hajela said in a statement. Simply put, addiction is not a choice. Addictive behaviors are a manifestation of the disease, not a cause..
The upper critical solution temperature (UCST) or upper consolute temperature is the critical temperature above which the components of a mixture are miscible in all proportions. solid state example is the palladium-hydrogen system which has a solid solution phase (H 2 in Pd) in equilibrium with a hydride phase (PdH n) below the UCST at 300 Â°C. Above this temperature there is a single solid solution phase.
Humidity is the amount of water vapor in the air. Water vapor is the gaseous state of water and is invisible. Humidity indicates the likelihood of precipitation, dew, or fog.Higher humidity reduces the effectiveness of sweating in cooling the body by reducing the rate of evaporation of moisture from the skin.bsolute humidity is the mass of the water vapor (), divided by the volume of the air and water vapor mixture (), which can be expressed as: The absolute humidity changes as air temperature or pressure changes.
