When the price elasticity of demand for a good is relatively inelastic (-1 < Ed < 0), the percentage change in quantity demanded is smaller than that in price. Hence, when the price is raised, the total revenue increases, and vice versa.
The inevitable broadening of peaks during the chromatographic process may make it difficult to discern two consecutive peaks in a chromatogram from each other. Such a situation will occur if the peaks overlap extensively. The ability to resolve two consecutive peaks is defined as the resolution and is given by; The widths of the two closely eluting peaks are nearly equal. For quantitative work a clear separation of peaks is necessary. However it is not necessary to have a large separation between the peaks (overkill).
Phase contrast microscopy is an optical microscopy technique that converts phase shifts in light passing through a transparent specimen to brightness changes in the image.n a phase contrast microscope, the image contrast is improved in two steps. The background light is phase shifted -90Â° by passing it through a phase shift ring.
