A spectrophotometric method for the quantitative analysis of Pb2+ in blood has a normal calibration curve for which Sstd=(0.296 ppb−1)×Cstd+0.003. What is the concentration of Pb2+ in a sample of blood if Ssamp is 0.397?
The velocity selector in the problem prior to this one is used in a mass spectrometer. Protons(with zero neutrons) are the most common hydrogen nuclei. Some hydrogen isotopes, however, haveeither one or two neutrons in addition to the proton. If a beam of hydrogen nuclei is shot into amagnetic eld of strength 2.0T and the nuclei do a u-turn after which they strike a detector, how farapart will the three isotopes be on the detector surface? Assume both protons and neutrons have amass of 1:67 10?27kg and e = 1:60 10?19C.Cont.
You are trying to come up with a drug to inhibit the activity of an enzyme thought to have a role in liver disease. In the laboratory the enzyme was shown to have a Km of 1.0 x 10-6 M and Vmax of 0.1 micromoles/min.mg measured at room temperature. You developed a competitive inhibitor. In the presence of 5.0 x 10-5 M inhibitor, the apparent Km of the enzyme was found to be 1.5 x 10-5 M. What is the Ki of the inhibitor?
Chemistry The levels of an organic pollutant (P) in the groundwater at the perimeter of a plant were a cause for concern. A 10 mL sample of the water was taken and the pollutant was extracted with 95% efficiency using 25 mL of diethyl ether. GC was used to analyse the concentration of P in diethyl ether. A calibration curve was plotted for a series of standards of P which yielded the following results: Peak Area Toluene Conc. (µg/ml) 12,000 2.6 23,700 5.0 35,500 7.7 46,800 9.9 31,250 Sample Determine the concentration of P in ppb in the initial groundwater sample.

In quality management, it is very important that you have a good background knowledge in both descriptive and inferential statistics. Since you already took up Biostatistics and Epidemiology during your Second Year, answer BRIEFLY the following questions on basic statistics: 1. Compare and contrast the three most common measures of central tendency mean, median and mode. 2. Differentiate standard deviation from coefficient of variation. 3. What is T-test?
You are trying to come up with a drug to inhibit the activity of an enzyme thought to have a role in liver disease. In the laboratory the enzyme was shown to have a Km of 1.0 x 10-6 M and Vmax of 0.1 micromoles/min.mg measured at room temperature. You developed an uncompetitive inhibitor. In the presence of 5.0 x 10-5 M inhibitor, the apparent Vmax was determined to be 0.02 micromoles/min.mg. What is the Ki of the inhibitor?
