Preload is an engineering term with several meanings. In the general sense, it refers to the internal application of stress to certain mechanical systems.
Front-End Engineering (FEE), or Front-End Engineering Design (FEED), is an engineering design approach used to control project expenses and thoroughly plan a project before a fix bid quote is submitted. [1] It may also be referred to as Pre-project planning (PPP), front-end loading (FEL), feasibility analysis, or early project planning.
Front-end loading (FEL), also referred to as Front-End Engineering Design (FEED), Front End Planning (FEP), pre-project planning (PPP), and early project planning, is the process for conceptual development of projects in processing industries such as upstream oil and gas, petrochemical, natural gas refining, extractive metallurgy, waste-to-energy, biotechnology, and pharmaceuticals.
The Sod shock tube problem, named after Gary A. Sod, is a common test for the accuracy of computational fluid codes, like Riemann solvers, and was heavily investigated by Sod in 1978. The test consists of a one-dimensional Riemann problem with the following parameters, for left and right states of an ideal gas .
On 14 November 2013 the P2 Steam Locomotive Company (P2SLC) announced that the name of its new P2 would be Prince of Wales, in honour of the 65th birthday of Charles, Prince of Wales. [39] Construction began in May 2014 with the locomotive's frames being cut at Tata Steel's Scunthorpe works. [40] The project cost is estimated at £5,000,000. [39]
The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET) [4] has defined "engineering" as: . The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to ...

Superoxide dismutase (SOD) mimetics are synthetic compounds that mimic the native superoxide dismutase enzyme. [1] SOD mimetics effectively convert the superoxide anion (O − 2 ), a reactive oxygen species , into hydrogen peroxide , which is further converted into water by catalase . [ 2 ]
