Submarine groundwater discharge (SGD) into a shallow lagoon on the west coast of Mauritius Island (Flic-en-Flac) was investigated using radioactive ((3)H, (222)Rn, (223)Ra, (224)Ra, (226)Ra, (228)Ra) and stable ((2)H, (18)O) isotopes and nutrients. SGD intercomparison exercises were carried out to validate the various approaches used to measure SGD including radium and radon measurements, seepa...
seepage in earth fill dams is one of the important factors that may cause the erosion and slope instability if it is ignored. therefore, it is crucial to calculate the leakage discharge through the body of dam and foundation, to prevent economic and life hazards by considering technical and economical issues. in this research, the seepage analysis of the body and the stability of the upstream a...
Background & Aims: The purpose of this study was to investigate the survey of scapular upward rotation and scapulohumeral rhythm in children, adults, and older people during abduction.Materials & Methods: Ninety subjects (30 children, 30 adults and 30 older people) volunteered for this study. Two inclinometers were used to measure humeral abduction and scapular upward rotation in scapular rest...
In this editorial, I pass on to a new team. South African Computer Journal has moved long way since took over as editor-in-chief 10 years ago and am pleased that we have new, enthusiastic team who will take it heights.

Background & Aims: Previous studies have stated that the scapulohumeral rhythm dysfunction can make a person prone to glenohumeral joint pathologies. The purpose of this study was to survey symmetric resting scapular posture and scapulohumeral rhythm ratio between dominant and non-dominant shoulders in elderly subjects in different humeral abduction angles. Materials & Methods: Thirty-five hea...
Dissolved methane and high resolution bathymetry surveys were conducted over the Rock Garden region of Ritchie Ridge, along the Hikurangi margin, eastern New Zealand. Multibeam bathymetry reveals two prominent, northeast trending ridges, parallel to subduction along the margin, that are steep sided and extensively slumped. Elevated concentrations of methane (up to 10 nM, 10× background) within ...
Groundwater is an important factor of slope stability, and 90% of slope failures are related to the influence of groundwater. In the past, free surface calculations and the prediction of water inflow were based on Darcy's law. However, Darcy's law for steady fluid flow is a special case of non-Darcy flow, and many types of non-Darcy flows occur in practical engineering applications. In this pap...
