BACKGROUND Hypohydration can have significant implications on normal physiological functions of the body. OBJECTIVES This study aimed to determine the impact of agitation, storage temperature, and storage time on urine osmolality compared to the criterion control. PATIENTS AND METHODS We used a descriptive diagnostic validity test design. To investigate… (More)
A line-tunable CO(2) laser system is described producing repeatable pulses with selectable widths from 2 to 60 nsec. High energy contrast ratio (minimum of 10) is achieved in both the P and R branches of the 9- and 10-microm bands making this system a valuable source for photochemical studies.
A laser-desorption mass-spectrometer microprobe has been developed to profile Li distributions on the crevice surfaces of Cr-plated rolled-joint hubs. A single laser pulse is used to desorb and ionize the surface species followed by detection of Li(+) in a time-of-flight mass spectrometer. Images of the surface Li distribution are obtained with a resolution… (More)
