Caffeine is a central nervous system (CNS) stimulant of the methylxanthine class. [9] It is mainly used as a eugeroic (wakefulness promoter) or as a mild cognitive enhancer to increase alertness and attentional performance.
The lake is divided into two sides by three stone dikes. The public side (also known as the "cold" side) is roughly 9,000 acres (36 km 2), while the private side (known as the "warm" side) is roughly 4,000 acres (16 km 2). The private side is formed of three main bodies of water, connected by navigable canals. This side has no marinas or public ...
Today in most societies people sleep during the night, but in very hot climates they may sleep during the day. [144] During Ramadan, many Muslims sleep during the day rather than at night. [145] In some societies, people sleep with at least one other person (sometimes many) or with animals.

They reach the cave full of ships and put out the remaining fires. Beau falls prey to a water spout and is hurled high into the air but Yasha uses her newly restored wings to catch Beau.
One option is temperature control—i.e., keeping all cold water below 25 °C (77 °F) and all hot water above 51 °C (124 °F). [3] Temperature affects the survival of Legionella as follows: [3] Above 70 °C (158 °F) – Legionella dies almost instantly; At 60 °C (140 °F) – 90% die in 2 minutes (Decimal reduction time (D) = 2 minutes)
In emergency medicine, safe administration of intranasal fentanyl with a low rate of side effects and a promising pain-reducing effect was demonstrated in a prospective observational study in about 900 out-of-hospital patients. [37] In children, intranasal fentanyl is useful for the treatment of moderate and severe pain and is well tolerated. [38]
An improved water source, as defined by the World Health Organization (WHO), refers to a drinking water source that provides adequate and safe water for human consumption. Examples of improved water sources include piped water connections, protected wells, boreholes with hand pumps, packaged or delivered water and rainwater collection systems ...
Fish and other organisms adapted to particular temperature range can be killed by an abrupt change in water temperature (either a rapid increase or decrease) known as "thermal shock". Warm coolant water can also have long term effects on water temperature, increasing the overall temperature of water bodies, including deep water.
