Similar growth stages of each plant species are given the same BBCH code. Each code has a description and important growth stages have additional drawings included. The first digit of the scale refers to the principal growth stage. The second digit refers to the secondary growth stage which corresponds to an ordinal number or percentage value.
Turnaround is a blanket term that encompasses more specific terms such as I&Ts (inspection and testing), and maintenance. Turnaround can also be used as a synonym of downtime . Related terms are shutdowns, and outages [ 1 ] sometimes written as Turnarounds, Shutdowns, and Outages (TSO).

It is a method in which a bud from the plant is joined onto the stem of another plant. [2] The plant in which the bud is implanted in eventually develops into a replica of the parent plant. The new plant can either divert its ways into forming an independent plant; however, in numerous cases it may remain attached and form various accumulations.
Front-end loading (FEL), also referred to as Front End Planning (FEP), pre-project planning (PPP), feasibility analysis, conceptual planning, programming/schematic design 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 ...
For the Calvin cycle to continue, RuBP (ribulose 1,5-bisphosphate) must be regenerated. So, 5 out of 6 carbons from the 2 G3P molecules are used for this purpose. Therefore, there is only 1 net carbon produced to play with for each turn. To create 1 surplus G3P requires 3 carbons, and therefore 3 turns of the Calvin cycle.
These are operated as 3-phase (vapour, oil and water) separators and are sized to provide 3 – 5 minutes of liquid residence time. Pressures are set to maximise gas separation at as a high a pressure as possible. Up to 5 stages of separation are common in the Gulf of Mexico and up to 4 stages on platforms in the North Sea. [4]
A 4-drum delayed coking unit in a petroleum refinery. A delayed coker is a type of coker whose process consists of heating a residual oil feed to its thermal cracking temperature in a furnace with multiple parallel passes.
