Conventional marine exploration offshore Nile Delta is challenged by shallow heterogeneities and a deep, complex anhydrite layer called the Messinian. These subsurface complexities cause variable illumination and strong diffracted multiples resulting in imaging challenges below the anhydrite on conventional narrow-azimuth towed streamer acquisition because the recording antenna is too small (Figure 1a). Additionally, it has proved difficult to build the detailed depth migration velocity model required to correctly image below the Messinian layer. Multi-azimuth (MAZ) acquisition using time-domain processing however, has been very successful in addressing both the noise and illumination problems in the Nile Delta. The increased azimuthal and crossline offset coverage—bigger antenna—is achieved by acquiring six conventional marine surveys over the same area at 30° sail-line increments (Figure 1b).

Summary‘New’ and ‘old’ suppositories (6months and30 months since manufacture) containing 800 mg paracetamol, 16 mg codeine phosphate and 12.5 mg buclizine hydrochloride in an identical base were administered to 10 normal volunteers at an interval of 2 weeks. Blood samples were taken at intervals up to 300 minutes after administration for estimation of paracetamol plasma concentrations using high pressure liquid chromatography. Mean peak concentrations were obtained of 4.75±0.74 mg/ml at 1.75 hours with the new suppositories and of 4.6±0.67 mg/ml at 2.0 hours with the old suppositories. The difference was not significant. Mean elimination half-life was 4.4±0.42hours and 3.73±0.28 hours, respectively. Again, the difference was not significant, indicating that the absorption characteristics for the suppositories did not appear to deteriorate with ageing for 24 months. Bioavailability data for paracetamol derived from the results were similar to those reported by other workers who studied suppositories containing paracetamol as the only active ingredient. This indicates that the inclusion of codeine phosphate and buclizine hydrochloride in the suppository formulation investigated in the present study did not affect adversely the absorption of paracetamol.
