Document Summary

The objective is to study the characteristics of shunt and series dc motors. For the first half of the experiment, half the lab groups will work with the shunt motor while the other groups will work the series motor. Afterwards, the groups will change workstations to complete the experiment. All experiments will be carried out using a fractional horsepower dynamometer test bed. Note: when starting a shunt motor, the field circuit must be energized first and then the armature circuit, or both circuits may be energized simultaneously. If the armature circuit is excited with no field, the motor may accelerate to a very high speed and high currents will be drawn: connect the d. c. shunt motor as shown in figure 1. F2: be sure to check meter ranges: Ammeter in the armature circuit 20 a dc. Ammeter in the field circuit 200 ma dc. Breaking current of the dynamometer: 0 on medium scale.

How do you arrive at this answer?

In a Wright-Fisher model with mutation and a (haploid) population of size 50, a new mutant arises in the population at time step zero, so that (initially) exactly one of the fifty genotypes in the population has the mutant allele. Assuming that the allele is selectively neutral, what is the probability that it will eventually become fixed in the population by random drift?
ANSWER: 0.02

Medical testing: enzyme linked immunosorbent assay (ELISA) test for presence of antigen or antibody

EXPERIMENTAL PROTOCOL

In this laboratory, you will test seven different patients using a direct ELISA. We have access to serum samples from the main characters of the TV show The Big Bang Theory. You will test each of them for the presence of ZIKA virus and HIV, as well as perform a pregnancy test, using known antigens/antibodies for those diseases/test. Students will work in pairs. Serum for each character of the Big Bang Theory has been incubated overnight at 4Â°C in the wells of an ELISA plate.
