Impedance plethysmography is a technique that can be used to detect thrombosis--the presence of clots in a blood vessel--by measuring the electrical resistance of a limb, such as the calf of the leg. In a typical clinical setting, a current of 200 μA is passed through the leg from the upper thigh to the foot. The voltage is measured at two points along the calf separated by 13 cm.
Part A:
If the voltage measured is 17 mV, what is the resistance of the calf between the electrodes?
Part B:
If the average calf diameter between the electrodes is 12 cm, what is the average resistivity of this part of the leg?

Design an indirect IF protocol that could be used to detect the
presence of antibodies to SARS CoV-2, the virus causing covid-19.
Assume that the specificity of the antibodies from patients would
be against epitopes on the spike proteins of the virus. Include
both a description of the protocol and a diagram showing the steps
of your protocol. (Draw the diagram, take a picture of it, and then
insert that JPEG image into this word document).
The anticoagulant heparin is used for preventing blood clots of patients after surgery, and for the treat- ment and prevention of deep vein thrombosis.

A company claims to have invented a hand-held sensor that can
detect the presence of explosives inside a closed container. Law
enforcement and security agencies are very interested in purchasing
several of the devices if they are shown to perform effectively. An
independent laboratory arranged a preliminary test. If the device
can detect explosives at a rate greater than chance would predict,
a more rigorous test will be performed. They placed four empty
boxes in the corners of an otherwise...
