The instantaneous rate is the change in the reactant or product at any given time and is determined by examining the slope of the curve in the plot of concentration vs time. As an example, reactant A's, instantaneous rate is represented as rate = -dA/dt. The rate law for a reaction...
Using the proposed approach, effective irradiance with respect to e.g., C(λ) curve (spectral sensitivity of the melatonin suppression) is the value to measure instead of illuminance. It is essential to make a distinction between photometric quantities and effective irradiance when the NIF effects...
Multicolor imaging that is developed on the Heidelberg systems gives a combined pseudo-color image using three different wavelengths including blue (486 nm), green reflectance (518 nm), and infrared (IR) reflectance (815 nm). The laser wavelength enhances each separate layer, with the surface of...
calibration curveDrug-induced acute interstitial nephritis (AIN) is a relatively common cause of hospital-acquired acute kidney injury (AKI). While prerenal AKI and acute tubular necrosis (ATN) are the most common forms of AKI in the hospital, AIN is likely the next most common. Clinicians ...
What is a Spectral Reflectance Curve? Using a spectrophotometer, you can measure an object to see how much light is reflecting at each point across the visible spectrum. Think of this color measurement like a fingerprint that is unique to that sample. The resulting reflectance data is that co...
fluorescent colors, the physical illumination must be adjusted to CIE D65 not only in the visible range, but also in the UV area below 400 nm. By measuring UV included and excluded, the built-in Xenon flash lamp of theColorXRA 45 Labspectrophotometer is adjusted to the CIE D65 standard....
Remote sensing is a set of advanced technologies based “on the information obtained from an object without physical contact, by measuring the electromagnetic energy reflected/backscattered or emitted by the surface of the target object” [83]. The spectral measurements acquired by portable instruments...
