ON CONTINUOUS CLINICAL TEMPERATURE CHARTS.

Small Clinical Charts

Clinical growth charts for pre-school children.

OBJECTIVE Growth standards are indicators for normal growth of the children and growth charts are important tools for their growth monitoring. Children from different populations are different in their growth pattern, it is important to create national standards for the growth of children in each population to develop local growth charts, and since these were not available in the Kingdom of Sau...

Operating charts for continuous sedimentation II: step responses

Abstract. The process of continuous sedimentation of particles in a liquid has often been predicted by means of operating charts and mass-balance considerations, where the underlying constitutive assumption is the one by Kynch. Much more complex operating charts (concentration-flux diagrams) can be obtained from a onedimensional model of an ideal continuous clarifier-thickener unit. The enginee...

Operating charts for continuous sedimentation I: control of steady states

The industrial process of continuous sedimentation of solid particles in a liquid takes place in a clarifier-thickener unit, which is a large tank with a feed inlet somewhere in the middle and outlets at the top and bottom. For half a century the constitutive assumption by Kynch has provided a platform from which steadystate mass-balance considerations have been used to obtain rules and graphic...

Operating charts for continuous sedimentation III: control of step inputs

Abstract. The main purposes of a clarifier-thickener unit is that it should produce a high underflow concentration and a zero effluent concentration. The main difficulty in the control of the clarification-thickening process (by adjusting a volume flow) is that it is non-linear with complex relations between concentrations and volume flows via the solution of a PDE – a conservation law with a s...
