Finally objective measurements of physical activity types at work constitute a valid and reliable measure that has not previously been used in prospective studies.
We compared measurements of physical linear distance with digital measurements.
All measurements of physical quantities are subject to uncertainties.
However, there is a lack of large-scale measurements of physical activity patterns across free-living populations worldwide1,6.
Nine studies compared students based on participation in gym classes or organized sports, rather than on measurements of physical activity.
Indicators may be direct measurements of physical changes, contaminants or biological and ecological effects, or proxy measurements of these attributes.
A well-accepted definition of frailty includes measurements of physical performance, which may limit its clinical utility.
relativity, special theory A theory formulated by Einstein that describes the relations between measurements of physical phenomena by two different observers who are in relative motion at constant velocity.
Biometric authentication is also used to prevent access by using measurements of physical characteristics to determine whether access will be granted.
High frequency measurements of physical, chemical and biological variables are being routinely made employing a moored platform (SmartBuoy) in UK shelf-seas.
Hardware development included that necessary to facilitate accurate and precise measurements of physical parameters by optical methods (pulse amplitude modulated fluorometry) and electrochemical sensors (ion-sensitive microelectrodes).
