Plumbing (mathematics) Plumbing two 1-disk bundles to get a new 2-manifold. In the mathematical field of geometric topology, among the techniques known as surgery theory, the process of plumbing is a way to create new manifolds out of disk bundles. It was first described by John Milnor [1] and subsequently used extensively in surgery theory to ...
Fixture unit. In plumbing, a Fixture Unit ( FU) or Drain Fixture Unit ( DFU) is "a unit of measure, based on the rate of discharge, time of operation and frequency of use of a fixture, that expresses the hydraulic load imposed by that fixture on the sanitary plumbing installation". [1] A Fixture Unit is not a flow rate unit but a design factor ...
Hospital emergency codes are coded messages often announced over a public address system of a hospital to alert staff to various classes of on-site emergencies. The use of codes is intended to convey essential information quickly and with minimal misunderstanding to staff while preventing stress and panic among visitors to the hospital.
Uniform Plumbing Code. Designated as an American National Standard, the Uniform Plumbing Code ( UPC) is a model code developed by the International Association of Plumbing and Mechanical Officials ( IAPMO) to govern the installation and inspection of plumbing systems as a means of promoting the public's health, safety and welfare.
Plumbing – the Maya have been found to be the earliest inventors of plumbing in Mesoamerica, with the earliest example of a pressurized water system being constructed in 750 CE—or earlier. This pressurized water system was located in the Maya site of Palenque , where public baths and toilets were accessible to the residents of the ancient city.
For example, a conventional heat pump system used to heat a building in Montana's −57 °C (−70 °F) low temperature or cool a building in the highest temperature ever recorded in the US—57 °C (134 °F) in Death Valley, California, in 1913 would require a large amount of energy due to the extreme difference between inside and outside air ...
Marian P. Roque is a Filipina mathematician. She was the president of the Mathematical Society of the Philippines, [1] a professor in the Institute of Mathematics of the University of the Philippines Diliman, [2] and former Director of the Institute of Mathematics. [3] Her mathematical specialty is the theory of partial differential equations.
The classical objects of interest in arithmetic geometry are rational points: sets of solutions of a system of polynomial equations over number fields, finite fields, p-adic fields, or function fields, i.e. fields that are not algebraically closed excluding the real numbers.
