This information is complemented by time-resolved NMR, fluorescence correlation spectroscopy, and steady-state absorbance and fluorescence measurements to provide a picture of chromophore ionization reactions spanning a wide time domain.
First, data were obtained retrospectively from patients imaged over a wide time span, who were unclassified by body size and diagnostic query, thus preventing us from finding any correlation between these latter parameters and per-patient radiation exposure.
Various studies were carried out over a wide time span, with the oldest study dating as far back as 1985.
This covered a wide time-span before, during and after the period of the mold sensitization study; some of the allergy study patients were admitted and recruited during this time but they represented only a small (and random) proportion of the admissions studied for seasonality.
The broadening of the significant results to include other child health outcomes results from the inclusion of more countries, and also from a wider time span.
These structural dynamics span a wide range of times, from the femtosecond time scale of crossing the transition state to the millisecond time scale of overall enzyme turnover, or slower.
In the last few years, many problems in science and engineering can be modeled accurately in the form of fractional calculus such as multi-scale problems that span a wide range of time or length scales.
Meanwhile, the present research could be the starting point of new researches investigating the implementation of the higher order thinking strategies in a wider time-span beyond one semester, and with the participants from other majors and discipline, or motivate the researchers to investigate the explicit training of these strategies.
Rates of substitution of metal-aqua ions have been found to span a wide range, the characteristic times required for substitution ranging from less than 10−9 second for monopositive ions, such as hydrated potassium ions, to several days for certain more highly charged ions, such as hexaaquachromium(3+) and hexaaquarhodium(3+).
The stories span a wide range of places and time periods.
