In all, 41 patients with traumatic dislocation of the hip, without associated acetabular or femoral fracture, were treated by two different methods after closed reduction, performed on average 2 h after injury. Patients in group A (N = 20) were subjected to skeletal traction for 2 weeks, followed by non-weight bearing for 3 months. Those in group B (N = 21)(More)
Gene flow in macroalgal populations can be strongly influenced by spore or gamete dispersal. This, in turn, is influenced by a convolution of the effects of current flow and specific plant reproductive strategies. Although several studies have demonstrated genetic variability in macroalgal populations over a wide range of spatial scales, the associated(More)
One of the main aspects when testing floating offshore platforms is the scaled mooring system, particularly with the increased depths where such platforms are intended. The paper proposes the use of truncated mooring systems to emulate the real mooring system by solving an optimization problem. This approach could be an interesting option when the existing(More)
Traumatic dislocations of the hip, while very infrequent injuries, must be treated with the utmost urgency. The later the adjustment is made, the sooner aseptic necrosis of the femoral head and periarticular ossification have to be reckoned with; these may lead to dysfunction. The results of 40 cases are reported, one-half of which was treated with two-week(More)
Wastewater outfalls provide a natural laboratory for the study of nutrient dynamics in coastal seas, however if properly designed and operated their impact can be difficult to detect. A model was developed and applied to investigate the effect of variation in hydrodynamic conditions on the transport and dilution of a treated wastewater plume in Belfast(More)
The long-term functional results of acetabular fractures are assessed in terms of the corresponding criteria of Merle-D'Aubigné and Postel (pain, mobility, walking). Other essential criteria include the quality of reduction and the radiological appearance. The age of the patient, the type of fracture and above all, the interval between the accident and the(More)

Arrays of tidal energy converters have the potential to provide clean renewable energy for future generations. Benthic communities may, however, be affected by changes in current speeds resulting from arrays of tidal converters located in areas characterised by strong currents. Current speed, together with bottom type and depth, strongly influence benthic(More)
