It is important to study the polymorphic changes of the drug as these changes may influence dissolution rate and bioavailability of the drug. X-ray powder diffraction measurements were performed on samples utilizing a diffractometer. The results were recorded over a range of 0 –50° (2θ) using the Xe-filled detector and Cu-target X-ray tube. For characterization of crystalline state‚ XRD patterns for pure Zolmitriptan

Abstract: A novel three-point method using a grating eddy current absolute position sensor (GECS) for bridge deflection estimation is proposed in this paper. Real spatial positions of the measuring points along the span axis are directly used as relative reference points of each other rather than using any other auxiliary static reference points for measuring devices in a conventional method. Every three adjacent measuring points are defined as a measuring unit and a straight connecting bar with

together. Diffraction refers to various phenomena which occur when a wave encounters an obstacle. In classical physics‚ the diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings. Isaac Newton thought that light must be a particle because particles of light that travels in straight lines until they are stopped by some object that blocks its path. When it is passed through a prism or a diffraction grating‚ the colors
