Young data collection

After these calculations, a least squares fit is done on the first 250 milliseconds of data to obtain the initial slope, which is Young s Modulus. This represents 5% or less of the data for a run of at least 2.4 seconds at an initial data collection rate of 100 points per second. 

We wish to express our appreciation to colleagues of the IUPAC Solubility Data Project, Rubin Battino and Colin L. Young for access to their data collections. ...

Other penetrometer-indentometers include transducers to sense the position and movement of the probe and microprocessors for temperature control and data collection and reduction. These instruments are used mainly to measure softening points, which are not glass transitions but are usually close to those values. Because a softening point is indicative of behavior under load, it is often more useful for predicting performance than the Tg. Penetrometer-indentometers can also be used to measure indentation hardness, creep, creep recovery, and modulus. Examples of such instruments include the TA Instruments, Mettler, Perkin-Elmer, Seiko, and Shimadzu thermomechanical analyzers (TMAs). They can be used to generate modulus and modulus-temperature data from indentation-time plots by applying the Hertz equation (eq. 36) (170,296), where E is the elastic or Young s modulus, jx the Poisson s ratio, r the radius of the hemispherical indentor, P the force on the indentor (mass load x g), h the indentation, and ifk the indentation hardness. 

Students and young professionals may be troubled by the inverted model. Presenting the conclusions and recommendations before describing the data collection and analysis procedures is certainly contrary to the way the work was actually done. But, most readers will not care what was done, other than to have the confidence that it was done correctly. They will focus on their areas of interest and the recommendations and implications for them or their constituencies. 

Voelkel and Fall [29] indicated that the significant variation in second virial coefficient data collected from different sources will affect the final result that is, the value of physico-chemical parameters describing the properties of polymer systems. Conder and Young [36] indicated that the permissible uncertainty when estimating the second virial coefficient of the solute should be 10% (at 20-50 °C).
