Water erosion prediction at a national scale for South Africa

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Local Diagnostic Reference Levels for Common Computed Tomography Procedures at a Tertiary Hospital in South Africa

Introduction: An operational computed tomography (CT) scanner is a major source of human exposure to ionizing radiation. Exposure increases the risk of cancer and aplastic anaemia. All radiation exposures should be justified and optimized to meet the clinical objective. In order to avoid the administration of excessive radiation dose to patients, diagnostic reference l...

Prediction equations for spirometry in South Africa.

Prediction equations for spirometry in South Africa To the Editor: The South African Guideline for Office Spirometry was recently published. [1] Its aim was to provide an updated guideline for office spirometry in South Africa (SA), thereby improving the quality, standardisation and usefulness of spirometry. The need for local prediction equations based on large, all­inclusive studies of the SA...

Workshops propose national programme for veterinary helminthology for South Africa.

A workshop was held at Onderstepoort on 2-3 July 1999 to set priorities in veterinary helminthology for South Africa. Representatives from 19 organisations attended. The workshop achieved 2 of its 3 aims, namely to identify the priority areas within the field and to set specific objectives to be achieved in addressing these needs. Seven strategies were proposed, namely, motivation, education, t...
