Write down the equation relating fluorescence intensity F to concentration C. Give two reasons why fluorescence is inherently a more sensitive analytical technique than absorbance for compounds that f What is the relationship between transmittance and absorbance? Show how to calculate the Ki of an in...
Calculate the energy of the photon emitted when an electron falls from n = 4 to n = 3. How does quantum theory explain the photoelectric effect? What does solar energy mean? How does the sun work using fusion and quantum tunneling?
Risk assessment (RA) of NMs encounters specific challenges that are not always taken into consideration in hazard assessment investigations. As a result, toxicological studies can face the exclusion from RA evaluations, due to the high risk of bias. Discordant hazard assessment data can be found ab...
To calculate the expected effect of a double perturbation on each parameter, fractional changes of the individual perturbations are multiplied, analogous to the way phenotypic growth effects caused by pairwise genetic interactions are assessed36. The error bars are calculated by error propagation of ...
(ωRF). When applied on resonance with the ES, the RF field saturates the ES magnetization, and this saturation can be transferred via conformational exchange to the GS. This typically results in a reduced signal intensity for the GS and a minor dip centered atωES = Δωwhen the RF...
To calculate the fluid loss from retinal blood-brain barrier we can use Starling equation for fluid filtration (Yuan and R.R., 2010), but to do this we need to estimate driving pressures and the hydraulic conductivity for the blood-brain barrier (in units of cm3 of transudate/s/cm H2O...
Measuring the anode current takes a bit more math. No calculus though, just ohm's law. Before we calculate anything though, let's set some variables. The meter is 100uA full scale deflection, and we'd like to make it 3mA. Looks like we'll need a resistor!
To calculate the total magnification of a traditional microscope with eyepieces and objectives, you … #diopter Sep 14th 2023 | Posted by BoliOptics How to Convert Diopters to Magnification Diopter indicates the amount of curvature of a lens. The thicker the lens, the bigger the curvatu … ...
What is the intensity of the laser beam? Explain why. Explain how light is emitted according to the quantum theory. Why are x-rays, rather than visible light or radio waves, used in Bragg diffraction from crystal surfaces? Explain how to calculate the wavelength of radio waves. How does a...
How can the field of view be used to calculate the size of an object under a certain magnification? Explain in mechanistic terms how the action potential is an all-or-none phenomenon. Differentiate between sensation and perception. Explai...
