Semiheavy water (HDO) is more common than pure heavy water, while heavy-oxygen water is denser but lacks unique properties. Tritiated water is radioactive due to tritium content. Heavy water has different physical properties from regular water, such as being 10.6% denser and having a higher melting point.
Moderate rain describes rainfall with a precipitation rate of between 2.6 millimetres (0.10 in) and 7.6 millimetres (0.30 in) per hour. Heavy rain describes rainfall with a precipitation rate above 7.6 millimetres (0.30 in) per hour, and violent rain has a rate more than 50 millimetres (2.0 in) per hour. [11]
Sleet warning WSW (alt.: heavy sleet warning) – Heavy sleet accumulations of 1 to 2 inches (2.5 to 5.1 cm) or more, which may cause significant disruptions to travel or utilities, are imminent or expected to occur within 12 hours. Discontinued beginning with the 2008-2009 winter storm season and replaced by the winter storm warning for heavy ...
As more moderate and heavy rain moved in Tuesday night, the National Weather Service issued a flood advisory for western San Luis Obispo County, warning of minor flooding in low-lying areas ...
The heavy water will slow down a significant portion of neutrons to the resonance integral of 238 U increasing the neutron capture in this isotope that makes up over 99% of the uranium in CANDU fuel thus decreasing the amount of neutrons available for fission. As a consequence, removing some of the heavy water will increase reactivity until so ...
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...

Very large amounts of heavy water must be consumed for any toxicity to become apparent. Rats, however, are able to avoid heavy water by smell, and it is toxic to many animals. [83] Light water refers to deuterium-depleted water (DDW), water in which the deuterium content has been reduced below the standard 155 ppm level.
