Problem 22.21
Resistivity measurements on the leaves of corn plants are a good way to assess stress and overall health. The leaf of a corn plant has a resistance of2.1M? measured between two electrodes placed20 cm apart along the leaf. The leaf has a width of2.8cm and is 0.20 mm thick.
Part A
What is the resistivity of the leaf tissue?
Part B
Is this greater than or less than the resistivity of muscle tissue in the human body?
Homework Answers
20 * 10 ^ 6=rho * .2/0.025*0.0002'
rho =20*10^6*0.025*0.0002/0.2
=500 ohm m
rho for human is 10 ohm /m
therefore its more

For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
