In computing, the menu key (≣ Menu), or application key, is a key with the primary function to launch a context menu with the keyboard rather than with the usual right-mouse button. [1] It was previously found on Microsoft Windows-oriented computer keyboards and was introduced at the same time as the Windows logo key.
Sodium was a massively multiplayer online game that was based in and exclusive to the PlayStation 3's online community-based social gaming network PlayStation Home. Sodium was a planned four-part series of games, only two of which were released by the time of Home's closure.
Windows 8.1 and Windows Server 2012 R2 restore the button back to its original place without removing the new button in the charms. [21] [22] On most versions of Windows, the Start button is located on the lower left corner of the screen, while the start button on Windows 11 is located in the center (but can be moved back to the lower left corner).
The sodium vapor process (occasionally referred to as yellowscreen) is a photochemical film technique for combining actors and background footage. It originated in the British film industry in the late 1950s and was used extensively by Walt Disney Productions in the 1960s and 1970s as an alternative to the more common bluescreen process.
The sodium channel selectivity filter is composed of a single residue in each of the four pore-loops of the four functional domains. These four residues are known as the DEKA motif. [52] The permeation rate of sodium through the sodium channel is determined by a four carboxylate residues, the EEDD motif, which make up the outer charged ring. [52]
In one study, transgenic mice over expressing this membrane protein were shown to have increased reabsorption and retention of sodium after increased salt intake. [3] In dopamine receptor signalling, [4] the widely expressed Na+/H+ exchanger NHE-1 is activated downstream of the D2, [5] D3, [6] [7] and D4 receptors. [8]
The sodium-calcium exchanger (often denoted Na + /Ca 2+ exchanger, exchange protein, or NCX) is an antiporter membrane protein that removes calcium from cells. It uses the energy that is stored in the electrochemical gradient of sodium (Na +) by allowing Na + to flow down its gradient across the plasma membrane in exchange for the countertransport of calcium ions (Ca 2+).
Sodium sulfide is a chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S·9H 2 O.Both the anhydrous and the hydrated salts in pure crystalline form are colorless solids, although technical grades of sodium sulfide are generally yellow to brick red owing to the presence of polysulfides and commonly supplied as a crystalline mass, in flake form, or as a fused solid.
