Why is the regulation of the radiant source less critical in a dual-beam spectrophotometer than it is in a single-beam spectrophotometer?
Why is the regulation of the radiant source less critical in a dual-beam spectrophotometer than it...
State the purpose AND describe how of each of the following elements in a dual-beam spectrophotometer functions: (a) source, (b) monochrometer, (c) sample cuvette, (d) reference cuvette, (e) detector
question: double beam UV - VIS spectrophotometer offer the advantge (s) of:- ( multiple choice question ) a) compensate for short term fluctuation in the radiant source and drifts in transducers b) compensate for variations in source intensity with wavelength c) enables continuos recording of absorbance of sample without the blank d) all of the above are correct
Is the future worth less than the present? Why or why not? If it is worth less, how much less?
5) p points) Temperature regulation is critical while preforming PCR. What could resuit IT the PCR reaction is not cooled to 42°C -65°C before the extension step? Why would this occur (2 points) If you start with one copy of a single gene of interest and perform PCR on that sequence, how many copies of the gene would you have after 10 cycles? Explain your reasoning.
What can be the limitations of critical path scheduling? Have a discussion of no less than 50 words.
Sound from source 3 has a sound intensity level that is 8.3 dB less than sound from source 1. By what factor is the sound intensity from source 3 less intense than the sound intensity from source 1? (Assume the sound intensities for sources 1 and 3 are I1 and I3, respectively.)
6. Explain why Nal scintillators are appropriate for single photon imaging but are less than ideal for PET imaging.
Explain why the market might provide less than the Pareto optimal amount of income redistribution. Is this an argument for using tax revenues as a source of income to redistribute? Explain both sides of the argument. Which side do you think is correct?
As a project manager, would you manage the critical path tasks differently than non-critical tasks? Why, or why not? If yes, what would you do differently?
Explain why to control a hazard at the source than with a PPE; with an example
