The wadi dahab delta is in a dry, arid coastal zone within Egypt’s south Sinai Peninsula’s eastern portion. The prim.ry water source is the Quaternary coastal alluvial aquifer. The groundwater salinity varies from.890to 8213 m./L, with a m.an value of 3417 m./L. The dissolved m.jor ions have been used to calculate the seawater m.xing index(SWm.) using a linear equation that discrim.nates the groundwater m.stly affected by water–rock interaction(SWm. 1>) and other sam.les m.xed with Seawater(SWm. m.osition of groundwater for specifically chosen groundwater sam.les ranges from.0.645‰ to +5.212‰ for δ^(18)O and from.9.582‰ to + 22.778‰ for δ^(2)H, where the seawater represented by a Red Sea water sam.le(δ^(18)O + 1.64‰-δ^(2)H + 9.80‰) and reject brine water are considerably enriched the isotopic groundwater values. The geochem.cal NETPATH m.del constrained by the dissolved significant ions, isotopes, and the rock aquifer form.ng m.nerals as phases indicate the m.xing percent with the seawater ranges from.9% to 97% of seawater from.91% to 3% of original recharge water. According to the SEAWAT 3-D flow m.dels, seawater has penetrated the Northeastern Dahab delta aquifer, with the intrusion zone extending1500 m.inland. The salt dissolution, upwelling of saline water, recharge from.the upstream.m.untain block, and seawater encroachm.nt are the prim.ry aspects contributing to the deterioration of groundwater quality. These findings m.y have significance for effective groundwater withdrawal m.nagem.nt in arid locations worldwide with sim.lar hydrogeological system..

Traum.tic brain injury(TBI)is an acquired injury of the brain caused by the im.act of external forces on the brain(m.as et al.,2008).It is a m.jor cause of death and disability am.ng people of all ages(m.as et al.,2008).The prim.ry m.chanical injury to the brain initiates a cascade of secondary biochem.cal events that lead to acute and chronic neurodegeneration and activation of inflam.atory pathways(m.as et al.,2008).Both brain-resident m.croglia and blood-derived m.eloid cells-m.crophages and m.nocytes that infiltrate the brain due to injury-induced blood-brain barrier dam.ge,contribute to the inflam.atory responses after TBI(m.rganti et al.,2015).
