In mathematics, the mice problem is a continuous pursuit–evasion problem in which a number of mice (or insects, dogs, missiles, etc.) are considered to be placed at the corners of a regular polygon. In the classic setup, each then begins to move towards its immediate neighbour (clockwise or anticlockwise).
While MCF and ICF attack the Lawson criterion problem from different directions, MTF attempts to work between the two. MTF aims for a plasma density of 10 19 cm −3, intermediate between MCF (10 14 cm −3) and ICF (10 25 cm −3) [3] At this density, confinement times must be on the order of 1 μs, again intermediate between the other two.
Ozone depletion is a separate problem caused by chlorofluorocarbons (CFCs) [233] which have been released into the atmosphere. [234] However, CFCs are strong greenhouse gases. [235] [236] Further, the hole in the ozone layer is shrinking and in 2019 was the smallest it had been since 1982, [237] [238] while global warming continues.
The first test was carried out on October 8, 2010, at slightly over 1 MJ. However, problems slowed the drive toward ignition-level laser energies in the 1.4–1.5 MJ range. [citation needed] One problem was the potential for damage from overheating due to a greater concentration of energy on optical components. [108]
Inertial confinement fusion (ICF) is a fusion energy process that initiates nuclear fusion reactions by compressing and heating targets filled with fuel. The targets are small pellets, typically containing deuterium ( 2 H) and tritium ( 3 H).
A report from Seton Hall University describes the suspension of a faculty member after lab mice were forced to live in "extremely dirty" conditions.
An ICF Core Set can serve as a reference framework and a practical tool to classify and describe patient functioning in a more time efficient way. ICF Core Sets can be used along the continuum of care and over the course of a health condition. [10] The ICF classification includes more than 1,400 categories limiting its use in clinical practice ...
This figure represents the evolution of the Rayleigh–Taylor instability from small wavelength perturbations at the interface (a) which grow into the ubiquitous mushroom shaped spikes (fluid structures of heavy into light fluid) and bubbles (fluid structures of light into heavy fluid) (b) and these fluid structures interact due to bubble merging and competition (c) eventually developing into ...
