Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.
Magma that cools slowly within a magma chamber usually ends up forming bodies of plutonic rocks such as gabbro, diorite and granite, depending upon the composition of the magma. Alternatively, if the magma is erupted it forms volcanic rocks such as basalt , andesite and rhyolite (the extrusive equivalents of gabbro, diorite and granite ...
Dungeon Keeper is a strategy video game developed by Bullfrog Productions and released by Electronic Arts in June 1997 for MS-DOS and Windows 95. In Dungeon Keeper, the player builds and manages a dungeon, protecting it from invading 'hero' characters intent on stealing accumulated treasures, killing monsters and ultimately the player's demise.
Magma emplacement can take place at any depth above the source rock. [4] Magma emplacement is primarily controlled by the internal forces of magma including buoyancy and magma pressure. [2] Magma pressure changes with depth as vertical stress is a function of the depth. [20] Another parameter of magma emplacement is the rate of magma supply. [2]
Because of its low viscosity, this is the least explosive form of magma. Basaltic magma may found in regions such as Hawaii, known for its shield volcanoes. [1], [7] Basaltic magma forms minerals such as calcium-rich plagioclase feldspar and pyroxene. The water composition of basaltic magma varies dependent on the evolution of the magma chamber.
Player versus player (PvP) is a type of multiplayer interactive conflict within a game between human players. [1] This is often compared to player versus environment (PvE), in which the game itself controls its players' opponents.
Player versus environment (PvE, also known as player versus monster (PvM) and commonly misinterpreted as player versus entity) is a term used for both single player and online games, particularly MMORPGs, CORPGs, MUDs, other online role-playing video games and survival games to refer to fighting computer-controlled enemies [1] - in contrast to PvP (player versus player) which is fighting other ...
As the magma develops over time and the crystal content of the magma increases, phase separation is taking place and the liquid phase of the magma is pushed up, driven by its buoyancy as a result of its lower density. Volcanoes, as valves of the open system, provide the path for gas release and magma eruption. The amount of dissolved gases may ...
