2. Sabu disk - Wikipedia

   en.wikipedia.org/wiki/Sabu_disk

   The artifact is made of schist (a term previously used in Egyptology for weakly metamorphic siltstone [2]), and is in the shape of a shallow bowl with a diameter of 61 centimetres (24 in) and a maximum height of 10.6 cm (4.2 in). Its central hole has a diameter of about 8 cm (3.1 in), which is fitted with a socket whose height corresponds ...

   There are several methods to increase the size of the brood chamber, if this is required: Use of a larger 14 in × 12 in (360 mm × 300 mm) box, where the height of the frame is 12 in (300 mm), instead of the standard 8 + 1 ⁄ 2 in (220 mm), and the box is thus either 12 + 3 ⁄ 8 in (310 mm) or 12 + 1 ⁄ 2 in (320 mm) tall. (This box is not ...

4. Langstroth hive - Wikipedia

   en.wikipedia.org/wiki/Langstroth_hive

   Three heights of boxes are standard—deep, medium, and shallow. Deep and medium hive bodies are used for the brood chamber. Medium and shallow supers are used for honey stores. The frames holding combs have top bars that hang on rabbeted slots or rails along the upper sides of a box. The deep hive body is normally used only for brood.

5. Undercroft - Wikipedia

   en.wikipedia.org/wiki/Undercroft

   An undercroft is traditionally a cellar or storage room, [1] often brick-lined and vaulted, and used for storage in buildings since medieval times. In modern usage, an undercroft is generally a ground (street-level) area which is relatively open to the sides, but covered by the building above.

6. Shallow trench isolation - Wikipedia

   en.wikipedia.org/wiki/Shallow_trench_isolation

   Shallow trench isolation (STI), also known as box isolation technique, is an integrated circuit feature which prevents electric current leakage between adjacent semiconductor device components. STI is generally used on CMOS process technology nodes of 250 nanometers and smaller.

7. Bearing capacity - Wikipedia

   en.wikipedia.org/wiki/Bearing_capacity

   Later investigations, however, have suggested that foundations with a depth, measured from the ground surface, equal to 3 to 4 times their width may be defined as shallow foundations. [ 4 ] Terzaghi developed a method for determining bearing capacity for the general shear failure case in 1943.
