Research ArticleOpen accessIn the abstractCoupled Hydrodynamic-Water Quality Model for Pollution Control Scenarios in El-Burullus Lake (Nile Delta, Egypt)A. El-Adawy, A. M. Negm, O. C. Saavedra V et al.El-Burullus Lake is affected by increasing and extensive human activities, rapid social-economic development and the construction of fish ponds nearby. This has significantly impacted the health of the lake eco-system. On the foundation of the two-dimensional depth averaged hydrodynamic model, distributions of the salinity, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Ammonium (NH4) were modeled. … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 10 Nov 2014 · 7,207 accessesView PDFCite
Research ArticleOpen accessIn the abstractREVIEW OF GRAVITATIONAL WAVE DETECTIONS: DYNAMICAL SPACEReginald Thomas CahillThis is a review of the numerous successful gravitational wave detections and the implications for the nature of space and time. The prevailing space time paradigm in physics was founded on the putative "null" results of the Michelson-Morley (MM) 1887 interferometer experiment to detect light speed anisotropy and which resulted in two different new relativity theories: Lorentz relativity (Lorentz, 1904) … …Physics International, Vol. 5, Issue 1 · 27 Mar 2014 · 8,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractACCELERATION AND PARTICLE FIELD INTERACTIONS OF COSMIC RAYS II: CALCULATIONSA. Tawfik, A. Saleh, M.T. Ghoneim et al.The Ultra High Energy Cosmic Rays (UHECRs) is still a one of the most controversial physical problems, especially that all potential acceleration mechanisms are not entirely able to explain the source of UHECR and their energy scale. Based on our generic acceleration model, that suggests different types of electromagnetic interactions between the cosmic charged particles and the different configurations of … …Physics International, Vol. 4, Issue 1 · 17 Jul 2013 · 7,196 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Bounded Expanding Carmelian White Hole Universe Without Dark MatterJohn Gideon HartnettThe solution of Einstein’s field equations in Cosmological General Relativity (CGR), where the Galaxy is at or cosmologically near the center of a finite yet bounded spherically symmetrical isotropic gravitational field, is identical with the unbounded solution. I show that this leads to the conclusion that the Universe may be viewed as a finite expanding white hole. The fact that … …Physics International, Vol. 3, Issue 2 · 7 May 2013 · 6,935 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultiple-Input Multiple-Output Transmission Over a Multipath Faded ChannelsI.A.Z. QatawnehThe use of multiple antennas at the transmitter as well as at the receiver can greatly improve the capacity of a wireless link when operating in a rich scattering environment. In such an arrangement all transmitting antennas radiate in the same frequency band so the overall spectral efficiency becomes very high. Such a multiple antenna scheme, popularly known as Multiple … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 11 Mar 2013 · 6,417 accessesView PDFCite
Research ArticleOpen accessIn the abstractSensor Technologies for Precision Soil Nutrient Management and MonitoringA. Bah, S. K. Balasundram, M. H.A. HusniProblem statement: Growing concerns about the need to increase crop productivity without causing environmental injury have led to the deployment of site-specific strategies in soil nutrient management, where nutrients are applied in variable rates to fit local requirements. Variable rate application of nutrients is typically based on a rigorous sampling regime and time-consuming data analyses. The ability to monitor soil … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 25 Jan 2012 · 9,127 accessesView PDFCite

Approach: A number of 25 sediment samples were collected from storm sewer inlets located in five residential areas in Kuwait: Bayan, Al-Nuzha, Al-Feiha, Al-Andalos and Al-Rumaithya. All the impervious areas for the … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,194 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeckle Suppression of Radar Images Using Normalized ConvolutionA. K. Helmy, G. S. El-TaweelProblem statement: Synthetic Aperture Radar (SAR) images are becoming more widely used in remote sensing applications. SAR uses microwave radiation to illuminate the earth's surface. The coherent microwave illumination, however, suffers from fading effects result in generating a multiplicative speckle noise that corrupts SAR images. Approach: Through this study, scheme to reduce speckles was proposed, it was designed to accomplish … …Journal of Computer Science, Vol. 6, Issue 10 · 5 Aug 2010 · 7,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractGene Technology in Tissue EngineeringXiao-Dan Sun, In-Seop LeeScaffold, cells and signaling factors are regarded as the three essential components in tissue engineering. With the development of molecular and cell biology, gene technology is beginning to show a promising position in tissue engineering as it can influence these essential components at DNA-level. By introducing plasmid DNA or genes encoding certain signaling factors (growth factors/cytokines) into the cells, required … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 6,401 accessesView PDFCite
