Material take off (MTO) is a term used in engineering and construction, and refers to a list of materials with quantities and types (such as specific grades of steel) that are required to build a designed structure or item.
Non-recurring engineering (NRE) cost refers to the one-time cost to research, design, develop and test a new product or product enhancement. [1] When budgeting for a new product, NRE must be considered to analyze if a new product will be profitable. Even though a company will pay for NRE on a project only once, NRE costs can be prohibitively ...
A specific material may be covered in several locations, depending on the work result: stainless steel (for example) can be covered as a sheet material used in flashing and sheet Metal in division 07; it can be part of a finished product, such as a handrail, covered in division 05; or it can be a component of building hardware, covered in ...
Engineer to order is a production approach characterized by: [1] Engineering activities need to be added to product lead time. Upon receipt of a customer order, the order engineering requirements and specifications are not known in detail. There is a substantial amount of design and engineering analysis required.
This article covers protein engineering [1] of cytochrome (CYP) P450 enzymes.P450s are involved in a range of biochemical catabolic and anabolic process. [2] Natural P450s can perform several different types of chemical reactions including hydroxylations, N,O,S-dealkylations, epoxidations, sulfoxidations, aryl-aryl couplings, ring contractions and expansions, oxidative cyclizations, alcohol ...
Bell announced its new project after the Bell 429 and Bell V-22, the super medium Bell 525, previously it was known as Project X or Magellan. The Helicopter is overall designed for trips of 50 to 500 nautical miles, and has a 5-blade main rotor powered by twin engines, digital controls and Garmin G5000H screen, with planned seating for 16-20 people.

It may also refer to a class of compounds, which are structurally related to the classical salen ligand, primarily bis-Schiff bases. Salen ligands are notable for coordinating a wide range of different metals, which they can often stabilise in various oxidation states. [1] For this reason salen-type compounds are used as metal deactivators.
The buffer should also be unreactive and not modify or react with most proteins. Different buffers may be used as cathode and anode buffers, respectively, depending on the application. Multiple pH values may be used within a single gel, for example in DISC electrophoresis. Common buffers in PAGE include Tris, Bis-Tris, or imidazole.
