Growth, optical, thermal and electrical properties of nonlinear optical ï§-glycine single crystal
Single crystal growth of γ-glycine has been grown by solution growth technique. The lattice parameters and crystal system of the grown crystals were confirmed by single crystal X-ray diffraction analysis. The functional groups present in the grown crystal were identified by FT-IR spectral analysis. The optical property of the γ-glycine crystal is studied by UV-Visible spectrum. Optical constants such as band...

Investigation of premature fracture of a tail pulley in the field
An unexpected (premature) failure happened in Tail Pulley during operation in field. Consequently, a complete analysis in terms of fracture and fatigue performed. The analysis aimed to determine the failure root-cause by the analysis of the project and materials. The analysis covered the tensions undergone by the pulleys under operation and the material´s mechanical strengths. The results showed the project...
