[1] Over 286 million Americans get their tap water from a community water system.

At about 5:20 a.m., after almost 80 minutes with a growing steam bubble in the reactor pressure vessel head, the primary loop's four main reactor coolant pumps began to cavitate as a steam bubble/water mixture, rather than water, passed through them. The pumps were shut down, and it was believed that natural circulation would continue the water ...

The Bishop score grades patients who would be most likely to achieve a successful induction. The duration of labor is inversely correlated with the Bishop score; “A Bishop score of 9 conveys a high likelihood for a successful induction. For research purposes, a Bishop score of 4 or less identifies an unfavorable cervix and may be an ...
Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage. [1][2] It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed.
Rupture of membranes. Rupture of membranes (ROM) or amniorrhexis is a term used during pregnancy to describe a rupture of the amniotic sac. [1] Normally, it occurs spontaneously at full term either during or at the beginning of labor.

[1] Testing blood for hCG results in the earliest detection of pregnancy. [2]
