Road safety depends on several factors associated with the vehicle, to the infrastructure, as well as to the environment and experience of vehicle drivers. Concerning the vehicle factors influencing the safety level of an infrastructure, it has been shown that the dynamic interaction between the carried liquid cargo and the vehicle influences the operational safety limits of the vehicle. A combination of vehicle and infrastructure factors converge when a vehicle carrying liquid cargo at a partial fill level performs a braking maneuver along a curved road segment. Such a maneuver involves both longitudinal and lateral load transfers that potentially affect both the braking efficiency and the lateral stability of the vehicle. In this paper, a series of models are set together to simulate the effects of a sloshing cargo on the braking efficiency and load transfer rate of a partially filled road tanker. The model assumes the superposition of the roll and pitch independent responses, while the vehicle is equipped with Anti-lock braking System brakes (ABS) in the four wheels. Results suggest that cargo sloshing can affect the performance of the vehicle on the order of 2% to 9%, as a function of the performance measure considered. A dedicated ABS system could be considered to cope with such diminished performance.

Oxyhemoglobin Dissociation

The development and improvement of an oxyhemoglobin dissociation curve analyzer is described. PO2 electrode performance was improved by electrochemical means and circuits are described for processing the PO2 and pH signalsfrom the analyzer. A circuit for automatically correcting the curve for Bohr shifts from pH 7.40 is described, and the performance of the Bohr shift unit is verified by experiment. The analyzer produces curves under standard conditions of PCO2 40 mmHg, pH 7.40, and 37 degrees C.
