The usual starting dose is 0.3 mL to 0.6 mL (about six to 12 drops) in a glass of water or juice four times a day. [31] Refractory cases (such as diarrhea resulting from the complications of HIV/AIDS ) may require higher than normal dosing, for example, 1 to 2 mL every 3 hours, for a total daily dose of up to 16 mL a day.
In osteichthyes, the gills contain 4 gill arches on each side of the head, two on each side for chondrichthyes or seven gill baskets on each side of the fish's head in lampreys. In fish, the long bony cover for the gill (the operculum) can be used for pushing water. Some fish pump water using the operculum.
Recipes for the potion appeared in the work of the popular English apothecary Nicholas Culpeper and the official pharmacopoeia handbooks of London and Amsterdam. Queen Elizabeth 's French ambassador was even treated with the remedy; however, the recipe was altered to include a "unicorn's horn" (possibly a ground-up narwhal tusk ) in addition to ...
[3] Pan-Galactic Gargle Blaster: The Hitchhiker's Guide to the Galaxy: 1978: A legendary cocktail invented by Zaphod Beeblebrox, based on "Old Janx Spirit." The effect of drinking it is "like having your brains smashed out by a slice of lemon wrapped round a large gold brick." [4] Many real-life recipes for this drink exist. Victory Gin ...
Lambertsen designed the LARU while a medical student and demonstrated the LARU to the Office of Strategic Services (OSS) (after already being rejected by the U.S. Navy) in a pool at the Shoreham Hotel in Washington D.C. in 1942 [3] [4] The OSS "Operational Swimmer Group" was formed and Lambertsen's responsibilities included training and developing methods of combining self-contained diving and ...
[3] [4] The inert gas and unused oxygen is kept for reuse, and the rebreather adds gas to replace the oxygen that was consumed, and removes the carbon dioxide. [3] Thus, the gas recirculated in the rebreather remains breathable and supports life and the diver needs only to carry a fraction of the gas that would be needed for an open-circuit system.
As a person breathes, the body consumes oxygen and produces carbon dioxide. Base metabolism requires about 0.25 L/min of oxygen from a breathing rate of about 6 L/min, and a fit person working hard may ventilate at a rate of 95 L/min but will only metabolise about 4 L/min of oxygen [10] The oxygen metabolised is generally about 4% to 5% of the inspired volume at normal atmospheric pressure, or ...
The normal relaxed state of the lung and chest is partially empty. Further exhalation requires muscular work. Inhalation is an active process requiring work. [4] Some of this work is to overcome frictional resistance to flow, and part is used to deform elastic tissues, and is stored as potential energy, which is recovered during the passive process of exhalation, Tidal breathing is breathing ...
