The M’za. region is subject to a. a.id Sa.a.a. clima.e where surfa.e a.d sub-surfa.e wa.ers a.e of little importa.ce. The Albian Aquifer, commonly called Continental Intercalary (CI), main component of North Western Sahara Aquifer System (NWSAS/SASS), constitutes the most extensive aquifer formation of the region. In our study area, the CI is identified, as a regional subset, as the Albian Aquifer of M’zab Region (AAMR). Its groundwater resources are considered the only source available to meet the growing needs of drinking water supply, agriculture and industry. This aquifer is heavily exploited by a very large number of wells (more than 750). Its supply is very low, so it is a very low renewable layer. This requires periodic monitoring and control of its piezometric level and its physico- chemical quality. The objective of our study is to know the current state of this aquifer, while studying the variation of its piezometry for the period 2010a. style="font-fa.ily:Verda.a.">

In this work. La.er Induced Brea.0}own Spectroscopy (LIBS) wa. used to determine the constituent of Gum a.a.ic (Acacia nilotica) collected from five different locations in Sudan. Gum samples were irradiated with 80 mJ pulse energy of Nd-YAG laser (1064 nm) and Atomic spectra Database was used for the spectral analysis of the plasma emitted from these samples. It was found that the samples contain the elements C, O, H, S, N, P, Na, Mg, Ca, Fe, Cr, Mn, Co with different amounts. Some elements like (Ti, Br, Ar, Th, Kr, Sc and Pr) are recorded here for the first time.

In this pa.era.>, in order to attain the maximum ergodic capacity and significantly increase the spectral efficiency of wireless communication systems, novel linear beamforming is proposed for dual-hop amplify-and-forward (AF) multi-relay networks. The linear beamforming is designed based on the maximization of the signal-to-interference-plus-noise ratio (SINR) and signal-to-a.> leakage-and-noise ratio (SLNR). The channel state information (CSI) is used in applying this new design to multi-relay (MR) nodes between the source a.d rela.s a. well a. rela.s a.d destina.ion. The bea.forming optimiza.ion problem is solved by using the Fukunaga-Koontz Transform (FKT). The scheme ca. a.hieve intra.node a.ra. a.d distributed ga.ns by using multiple a.tenna. a.d multi-rela.s (MRs). The performa.ce of the proposed scheme demonstra.es tha. by considering interference mitiga.ion criteria.the ergodic ca.a.ity at a significant level is improved as compared to the conventional techniques. Therefore, the proposed techniques ba.ed on the ma.imiza.ion of the signal-to-interference-plus-noise ratio (SINR) and signa.-to-lea.8}ge-a.d-noise ra.io (SLNR) rela. processing outperform other conventiona. techniques in ca.e of a.multi-rela. dua.-hop network.in terms of ergodic.
