Our project uses the Global Positioning System (GPS) to monitor and quantify patterns and rates of tectonic and mag-matic deformation associated with active rifting of the continental lithosphere in the northern Red Sea and the transition to sea floor spreading in the central Red Sea. Figure 1 shows the current network and preliminary velocities for GPS(More)
The phenolic composition of sumac root barks was studied. Colorimetric assays, FT-IR and NMR were used to examine the phenolic composition and tannins nature. Matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry was used to examine the structure of the tannin oligomers. TGA analysis was used to study the thermal stability(More)
