The aim of this work is to determine mean diameter of polycrystalline samples using Scherrer equation. These represent direct connection between mean diameter and crystal structure and morphology by including the Bragg angle and shape factor. Two samples are investigated, first a nano-sized particles of MgO and second a CVD (Chemical Vacuum Deposition) obtained polycrystalline aluminum film. Fi...
Biomass measurement is important in terms of ecological and economical evaluation of the structure and conditions of habitat and can provide an estimate for carbon sequestration in different organs of tree. In order to assess the amount of biomass in harvested and unmanaged Beech stands, two compartments (511 and 514) of Safaroodchr('39')s forest were selected. A plot of 6.25 hectare from e...
