Typhoon-class submarines feature multiple pressure hulls that simplify internal design [clarification needed] while making the vessel much wider than a normal submarine. In the main body of the sub, two long pressure hulls lie parallel side by side, with a third, shorter pressure hull above and partially between them (which protrudes just below ...
Many reactor designs (such as that of the Molten-Salt Reactor Experiment) allow the fuel/coolant mixture to escape to a drain tank, when the reactor is not running (see "Fail safe core" below). This tank is planned to have some kind (details are still open) of passive decay heat removal, thus relying on physical properties (rather than controls ...
Grace Wang’s image of a Florida bass and Emma Nemes’ depiction of a snook were selected from hundreds of submitted works by students as the new freshwater and saltwater designs, the FWC said ...
Marine architecture is the design of architectural and engineering structures which support coastal design, near-shore and off-shore or deep-water planning for many projects such as shipyards, ship transport, coastal management or other marine and/or hydroscape activities.
Salt evaporation pond in Manaure, La Guajira, Colombia. A salt evaporation pond is a shallow artificial salt pan designed to extract salts from sea water or other brines.The salt pans are shallow and expansive, allowing sunlight to penetrate and reach the seawater.
A solar pond is a pool of saltwater which collects and stores solar thermal energy. The saltwater naturally forms a vertical salinity gradient also known as a "halocline", in which low-salinity water floats on top of high-salinity water. The layers of salt solutions increase in concentration (and therefore density) with depth.
Marine aquarists typically divide saltwater aquariums into those housing fish only, those housing fish with live rock, and those primarily designed to house corals and other invertebrates (also known as reef aquariums). Many fish hobbyists also divide the types of saltwater tanks based on the water temperatures at which they are kept. [5]
In this book, Gosse primarily discussed saltwater aquaria. [19] In the 1850s, the aquarium became a fad in the United Kingdom. [20] Tank designs and techniques for maintaining water quality were developed by Warington, later cooperating with Gosse until his critical review of the tank water composition.
