Retention of dentures was measured by using a spring scale. All measurements were recorded in grams.
After this time, with mouth opened and lower lip relaxed in order to avoid losing peripheral seal, tip of spring scale was placed at the margin of denture, in recess of lingual frenum.
The bias in this study may include observation bias during recording the data by using spring scale. These biases were prevented by standardization of technique using a digital spring scale.
My favorite milk scale is a brass-front spring scale manufactured for the Better Farming Co., Union City, Pa., by Landers, Frary & Clark.
Except for time taken to weigh, the spring scale seems to be competitive for accuracy.
My first collection consisted of more than 30 spring scales used as milk scales on dairy farms.
A 30-g spring scale was used to measure force and was suspended above the flume.
The spring scale measurement for the Wildlife Computers PAT increased from 6.50 g at 0.00 m/s to 19.0 g at 0.60 m/s and the Microwave Telemetry PTT increased from 11.75 g to 21.5 g over the same flume velocity increase (Table 1).
Table 1 Spring scale measurements, angle of deflection, summary of forces exerted and power required for two brands of PSAT over flume velocities from 0.00 m/s to 0.60 m/s.
There are two types of spring scales
you are likely to see.
Angry at this, he checked the weight on the new electronic scales and it was a fraction over the 60g limit, yet on the old spring scales
it was within it.
The various dyads were audiotaped, and the tapes were analyzed for the kinds of interactions taking place and for evidence of concept development as the students worked with the various levers, spring scales
, and related materials.
