    Notes: Temperature logs were used to study the movement of water injected into wells penetrating the Pliocene Ogallala Formation in the High Plains of Texas. Descriptions of the results of three recharge tests are necessary because the hydrologic response to recharge at each site was very different. The water used for artificial recharge of the aquifer was derived from playa lakes in which the diurnal fluctuation of temperature was as much as 17 ° Celsius. Daily thermal cycles that resulted from injection of this water were traced through the aquifer by use of a series of temperature logs made at frequent intervals in cased holes specially constructed for logging. The thermal pulses were detected by logging holes as far as 46 meters (150 ft) from the recharge well.In areas where this technique was used, the Ogallala Formation consists of thick sections of uniform medium-grained sand that visually appear uniform and thus were thought to have uniform hydraulic conductivity. However, the results of temperature logging at each of the three sites clearly demonstrate that the hydraulic conductivity varies greatly through these seemingly uniform lithologic units. Thermal pulse velocities as high as 4.6 meters (15 ft) per hour were found in thin zones immediately adjacent to sand where velocities were a few feet per day. Tracing with temperature logs is potentially useful in locating zones of high intrinsic permeability and in detecting apparent changes in rate of flow as a function of time.

    Compartmental modelling based on methionine tolerance test data: a case study (1979)
    Springer

    Notes: Abstract A case study illustrates the application of systems theory to the analysis of data from nonrepeatable experiments with relatively few data points. The specific problem considered is the compartmental modelling in the human of the metabolic pathways of orally-administered methionine using tolerance test data. Attention is restricted to linear models, and concentrates on the determination of parsimonious structures (i.e. with as few parameters as possible) and their physiological interpretation.

    Adequacy of measurements in compartmental modelling of metabolic systems (1979)
    Springer
    Medical & biological engineering & computing 17 (1979), S. 216-222

    Notes: Abstract The adequacy of present-day measurement techniques for the compartmental modelling of metabolic systems is investigated using numerical examples and analysis of experimentally-obtained plasma clearance curves. It is concluded that the model parameters obtained are often of questionable accuracy. The situation can be improved by careful monitoring of experimental conditions and judicious spacing of data points on the response curve, but the work shows a clear need for a continuous (or semicontinuous) method of monitoring plasma concentration. To resolve ambiguities between models equally plausible on physiological grounds, it is necessary to monitor the dynamics of internal variables, for example, of the concentration in the liver (which is nowadays possible noninvasively).
