the non-destructive meyer method was evaluated to determine the bark volume of beech (fagus orientalis lipsky) stands in north of iran. the sample size was 185 standing trees collected from 4 geographical aspects (north, south, west and east) aspects. the constant k values and bark thickness (2e mm) of 185 standing trees were used to calculate the bark volume by the meyer method. in this study,...

Reinforced concrete structures are typically exposed to a combination of aggressive substances and mechanical stresses, which contribute fast degradation. The present research was conducted evaluate five time-dependent parameters from several different tests, namely compressive strength, static modulus, dynamic surface, bulk electrical resistance. Some were obtained using destructive testing (D...

Abstract: Refractory materials containing cordierite (2MgO.2Al2O3.5SiO2) and mullite (3Al2O3.2SiO2) are used as support in furnaces, because of their low thermal expansion properties which confer them a very good ability to thermal shock resistance. Composed of two phases presenting very different CTE (1.5–3×10-6 for cordierite and 4–6×10-6 K-1 for mullite), these materials can develop damag...

therefore, the objective of this study is to test the feasibility of uv-ir transmission spectroscopy for the non-destructive assessment of the freshness of an individual egg as an alternative for traditional inspection methods. to obtain a considerable variation in freshness, groups consisting of 10 eggs were stored (30 7 oc and 25% 4 rh) for 30 days. data obtained from non-destructive spectral...
