Catgut suture in a vintage glass dispenser. Catgut suture is a type of surgical suture made of twisted strands of purified collagen taken from the small intestine of domesticated ruminants or beef tendon. It is naturally degraded by the body's own proteolytic enzymes.
Catgut (also known as gut) is a type of cord [1] that is prepared from the natural fiber found in the walls of animal intestines. [2] Catgut makers usually use sheep or goat intestines, but occasionally use the intestines of cattle , [ 3 ] hogs , horses , mules , or donkeys . [ 4 ]
The bottom water of the Arctic Ocean is more isolated, due to the topography of the Arctic Ocean floor and the surrounding Arctic shelves. Deep Western Boundary Currents carry the Antarctic Bottom Water northward in the South Atlantic Ocean. The Antarctic Bottom Water shifts east when it reaches the equator, thus turning it into an eastern ...
Both experts agree it’s best to store water in glass bottles with closed caps. Riese is a strong believer in glass bottles, “as glass does not give anything to water or of water, so it’s the ...
in the condensation of the water-vapour of the air on the cold surface of a glass; in the capillarity of hair, wool, cotton, wood shavings, etc.; in the imbibition of water from the air by gelatine; in the deliquescence of common salt; in the absorption of water from the air by concentrated sulphuric acid; in the behaviour of quicklime".

The variation in the depth of the CCD largely results from the length of time since the bottom water has been exposed to the surface; this is called the "age" of the water mass. Thermohaline circulation determines the relative ages of the water in these basins.
Chorda filum, commonly known as dead man's rope or sea lace among other names, is a species of brown algae in the genus Chorda.It is widespread in the temperate waters of the northern hemisphere.
Antarctic bottom water is formed in the Weddell and Ross Seas, off the Adélie Coast and by Cape Darnley from surface water cooling in polynyas and below the ice shelf. [7] An important factor enabling the formation of Antarctic bottom water is the cold surface wind blowing off the Antarctic continent. [8]
