Chelating resin. Chelating resins are a class of ion-exchange resins. They are almost always used to bind cations, and utilize chelating agents covalently attached to a polymer matrix. Chelating resins have the same bead form and polymer matrix as usual ion exchangers. Their main use is for pre-concentration of metal ions in a dilute solution.
Trace gas. Trace gases are gases that are present in small amounts within an environment such as a planet 's atmosphere. Trace gases in Earth's atmosphere are gases other than nitrogen (78.1%), oxygen (20.9%), and argon (0.934%) which, in combination, make up 99.934% of its atmosphere (not including water vapor).
Trace (linear algebra) In linear algebra, the trace of a square matrix A, denoted tr (A), [1] is defined to be the sum of elements on the main diagonal (from the upper left to the lower right) of A. The trace is only defined for a square matrix ( n × n ). It can be proven that the trace of a matrix is the sum of its eigenvalues (counted with ...

Horse logging is the use of horses or mules in forestry. In the modern industrialized world, it is often part of sustainable forest management . Horses may be used for skidding and other tasks. [1] Net net and gross production rates using horse logging in a Romanian study were of 2.63 m 3 /h and 1.44 m 3 /h. [2]
Tracer use in the oil industry. Tracers are used in the oil industry in order to qualitatively or quantitatively gauge how fluid flows through the reservoir, [1] as well as being a useful tool for estimating residual oil saturation. Tracers can be used in either interwell tests or single well tests. [2]
