|Coils for broadcast frequencies (550 to 1,500 kc) are usually also single-layer |
solenoids, although bank and universal windings are sometimes employed. At
frequencies below 550 kc, the coils for resonant circuits are nearly always

|This latter arrangement is known as the universal shunt. An analysis based on |
Fig. l-2c shows that the relative multiplying ratio is proportional to R/Ri, and is
independent both of the meter resistance and of the total shunt resistance R.
|The total resistance R of the universal shunt must be such that at position 2 in Fig. |
26 the proper full-scale deflection will be obtained. An alternative arrangement is
to make R greater than this value, and then to connect across R an additional ...
|In medical schools the common practice is to charge research grants and |
contracts for faculty time devoted to sponsored research. In certain other fields,
such as physics and chemistry, the more common (but not universal) practice is

|In certain other fields, such as physics and chemistry, the more common (but not |
universal) practice is for the institution to make no charge against extramural
funds for the time spent on research by tenured faculty members, while at the
