Research ArticleOpen accessIn the abstractA Contribution of the CDP Gathers and Pre-Stack Seismic Inversion in the Prospect Evaluation: A Case Study of El Mansoura Field, Nile Delta, EgyptMohamed Hussein, Ahmed Abu El-Ata, Mohamed El-BehiryThis case study showing the usefulness of the Common Depth Point (CDP’s) analysis to assess the amplitude response which is similar at two cases (gas-bearing and dry sands) after stack, using the Amplitude Versus Offset (AVO) analysis and the pre-stack inversion to understand the reservoir configuration and its relationship to the different amplitude response. The results led to a high … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 24 Jul 2019 · 7,798 accessesView PDFCite
Review ArticleOpen accessIn the abstractOn Mars there was WaterFlorian Ion Tiberiu PetrescuScientists overseeing Curiosity's mission on Mars confirmed that the shape and size of the pebbles on the dry tracks indicate that they were transported and eroded by the waters. According to them, the rover found the roots of rocks equivalent to the flowing waters on Earth. The planet Mars, the closest to Terra, had life conditions similar to our blue … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 11 May 2018 · 8,640 accessesView PDFCite

Research ArticleOpen accessIn the abstractHYPOLITHIC CYANOBACTERIA COLONIZATION OF QUARTZ AT SOUTH DESERTRoda F. Al-ThaniHypolithic microbial communities (found underneath rocks) were encountered in the southern desert of Qatar where quartz rocks are ubiquitous and are a substrate for hypoliths. These hypoliths thrive where extreme temperature, moisture stress and high light intensity limit the occurrence of higher plants and animal life. A small-scale ecological survey indicated that 80% of the quartz rocks in the area … …OnLine Journal of Biological Sciences, Vol. 14, Issue 1 · 11 Feb 2014 · 7,306 accessesView PDFCite
