    Robinson's retirement was announced in April 2019. It was Lord Cavendish in his role as chair of the Guide Over Sands Trust who visited the 86-year-old Robinson and suggested that it was time to retire: "'At the age you've got to, Mr Robinson – Cedric,' he said, 'we'd like to take the responsibility away from you and we would like you to choose a new guide'".

  3. Thermal barrier coating - Wikipedia

    en.wikipedia.org/wiki/Thermal_barrier_coating

    An effective TBC needs to meet certain requirements to perform well in aggressive thermo-mechanical environments. [2] To deal with thermal expansion stresses during heating and cooling, adequate porosity is needed, as well as appropriate matching of thermal expansion coefficients with the metal surface that the TBC is coating.

    Size ranges define limits of classes that are given names in the Wentworth scale (or Udden–Wentworth scale named after geologists Chester K. Wentworth and Johan A. Udden) used in the United States. The Krumbein phi (φ) scale, a modification of the Wentworth scale created by W. C. Krumbein [1] in 1934, is a logarithmic scale computed by the ...

    A QFL diagram or QFL triangle is a type of ternary diagram that shows compositional data from sandstones and modern sands, point counted using the Gazzi-Dickinson method. The abbreviations used are as follows: Q – quartz; F – feldspar; L – lithic fragments

  8. Reynolds number - Wikipedia

    en.wikipedia.org/wiki/Reynolds_number

    The size of the largest scales of fluid motion (sometimes called eddies) are set by the overall geometry of the flow. For instance, in an industrial smoke stack, the largest scales of fluid motion are as big as the diameter of the stack itself. The size of the smallest scales is set by the Reynolds number.

  9. Roundness (geology) - Wikipedia

    en.wikipedia.org/wiki/Roundness_(Geology)

    F=f(Sh, A, R, Sp, T) where f denotes a functional relationship between these terms and where Sh denotes the shape, Sp the sphericity and T the micro-scale surface texture. [ 2 ] An example of this practical use has been applied to the roundness of the grains in the Gulf of Mexico in order to observe the distance from the source rocks.
