This is a list of software that provides an alternative graphical user interface for Microsoft Windows operating systems. The technical term for this interface is a shell. Windows' standard user interface is the Windows shell; Windows 3.0 and Windows 3.1x have a different shell, called Program Manager. The programs in this list do not restyle ...
The type found deposited on the heating elements of water heaters consists mainly of calcium carbonate (CaCO 3). Hard water contains calcium (and often magnesium ) bicarbonate or similar ions. Calcium, magnesium, and carbonate ions dissolve from rocks through which rainwater percolates before collection.
In brewing, a carboy or demijohn is a glass or plastic vessel used in fermenting beverages such as wine, mead, cider, perry, and beer. Usually it is fitted with a rubber stopper and a fermentation lock to prevent bacteria and oxygen from entering during the fermentation process.
A fermentation lock or fermentation airlock is a device used in beer brewing and wine making that allows carbon dioxide released during fermentation to escape the fermenter, while not allowing air to enter the fermenter, thus avoiding oxidation. There are two main designs for the fermentation lock. These designs work when half filled with water.
A ceramic heater as a consumer product is a space heater that generates heat using a heating element of ceramic with a positive temperature coefficient (PTC). [1] [2] [failed verification] Ceramic heaters are usually portable and typically used for heating a room or small office, and are of similar utility to metal-element fan heaters.
Comprehensive set of tools for finite element codes, scaling from laptops to clusters with 100,000+ cores. Written in C++, it supports all widely used finite element types, serial and parallel meshes, and h and hp adaptivity.
The water is filtered by either a two-stage or three-stage filtration process, involving a carbon filter, and two de-ionization filters, or a carbon filter, a reverse osmosis membrane filter, and a de-ionization resin filter. The filtered water should contain a TDS (total dissolved solids) of 0 ppm (parts per million) when being used on windows.
The "Vessel Boiling Electric" or "BV" was an innovation at the very end of World War II, when the Centurion tank was introduced with the device fitted inside the turret. [2] [3] Previously, British tank crews had disembarked when they wanted to "brew-up" (make tea), using a petrol cooker improvised from empty fuel cans [4] called a "Benghazi burner". [5]
