Rimstone, also called gours, is a type of speleothem (cave formation) in the form of a stone dam. Rimstone is made up of calcite and other minerals that build up in cave pools. The formation created, which looks like stairs, often extends into flowstone above or below the original rimstone. Often, rimstone is covered with small, micro-gours on ...
Early Bronze Age stone wrist-guards are found across Europe from around 2400-1900 BC and are closely associated with the Beaker culture and Únětice culture. In the past they have been variously known as stone bracers , stone arm-guards and armlets , although "stone wrist-guard" is currently the favoured terminology; [ 1 ] and it is no longer ...
Stone was laid down on 14 September 2018, launched on 4 October 2019 by Huntington Ingalls Industries and christened on 29 February 2020. She will be expected to be commissioned in February 2021. Her sea trials took place on 15 September in the Gulf of Mexico and was successfully delivered to the Coast Guard on 10 November 2020. [8]
Commander Elmer "Archie" Stone was inducted into the United States Naval Aviation Hall of Honor on May 5, 1983, and is also a member of the U.S. Coast Guard Aviation Hall of Fame. Stone was a pivotal figure in the establishment and development of aviation for the Coast Guard and the Navy and was a favorite of many of the famous aviation figures ...
The pore is formed by two guard cells, which control the size of the pore by swelling in response to the activity of the H +-ATPase. Opening and closure of the pore is partly controlled by regulation of the H +-ATPase. Plant movements. Like the somatal pore, other movements of plant organs are controlled by motor cells' changing cell turgor.
Most useful ATP analogs cannot be hydrolyzed as ATP would be; instead, they trap the enzyme in a structure closely related to the ATP-bound state. Adenosine 5′-(γ-thiotriphosphate) is an extremely common ATP analog in which one of the gamma-phosphate oxygens is replaced by a sulfur atom; this anion is hydrolyzed at a dramatically slower rate ...
The energy required for the proton pumping reaction may come from light (light energy; bacteriorhodopsins), electron transfer (electrical energy; electron transport complexes I, III and IV) or energy-rich metabolites (chemical energy) such as pyrophosphate (PPi; proton-pumping pyrophosphatase) or adenosine triphosphate (ATP; proton ATPases).
For every ATP molecule that the pump uses, three sodium ions are exported and two potassium ions are imported. [1] Thus, there is a net export of a single positive charge per pump cycle. The net effect is an extracellular concentration of sodium ions which is 5 times the intracellular concentration, and an intracellular concentration of ...
