If unable to pay, customers face disconnection, the utility loses revenue, and the service provision model is undermined. A possible solution to this problem is prepaid metering, in which customers buy electricity upfront and use it until the prepaid amount is consumed. We us...

BACKGROUND Non-communicable diseases and associated risk factors (smoking, alcohol abuse, physical inactivity and unhealthy diet) are a major contributor to primary care morbidity and the burden of disease. The need for healthcare-provider training in evidence-based lifestyle interventions has been acknowledged by the National Department of Health. However, local studies suggest that counsellin...

Polycythemia in carriers of hemoglobin J Cape Town or hemoglobin Chesapeake is thought to be produced by increased oxygen affinity of their blood. Both hemoglobins involve substitution of amino acid residue alpha FG-4. Measurements reported here, of the oxygen equilibrium of purified hemoglobin J Cape Town, permit direct comparison of the two hemoglobins. J Cape Town exhibits lower oxygen affin...

Cape Colony, and towards the end of the year at Natal. It continued at various points in the beginning of 1862. Diphtheria was seen among the children of the civil population at Keisham Hoeck, in March 1862; and what is denominated ulcerated sore throat, with a tendency to catarrhal and bronchitic affections, was frequent at Cape Town, Port Elizabeth, and Fort Beaufort.
