This paper is devoted to prove the existence of an exponential attractor for the semiflow generated by.a nonlinear Boussinesq equation. We formulate the Boussinesq equation as an abstract equation in the Hilbert space H0^2（0, 1） × l^2（0, 1）. The main step in this research is to show that there exists an absorbing set for the solution semiflow in the Hilbert space H0^3（0, 1） × H0^1（0, 1）.

In this paper, under the hy.othesis that y.is upper bounded, we construct a ly.punov functional for the multidimensional isentropic compressible magnetohy.rody.amic equations and show that the weak solutions decay.exponentially.to the equilibrium state in l2 norm. Our result verifies that the method of Daoy.an Fang, Ruizhao Zi and Ting Zhang I1] can be adapted to magnetohy.rody.amic equations.

The design and analy.is of special ty.e beam former, the Butler matrix, toachieve orthogonal beam-forming networks is presented in this paper. A 4 X 4 microstrip planar array.ntenna is assumed to simulate a 4 X 4 Butler matrix to demonstrate orthogonal beam forming andbeam steering. The dimensions of rectangular patches in the planar array.are chosen according to theDolph-Cheby.hev current distribution in order to minimize the side-lobe level ratio for a givenvalue of beamwidth. The simulations are carried out using an antenna design and analy.is softwarePCAAD. It is shown that orthogonal beams can be formed to cover about 163° angle with a constantbeam crossover level and high directivity.

The ISM band at 2.4 GHz has mostly.been used or planned for indoor *** band is also attractive for outdoor sy.tems owing to the ease of the sy.tem deploy.ent, as nofrequency.licenses are required. In this paper, a multiple successive internal multireflection modelis used to estimate the complex electric permittivity.at 2.4 GHz band. To obtain the data,measurements are performed at 160 MHz bandwidth centered about 2. 4 GHz using a vector networkanaly.er, which provides information about the am.litude and phase of transmission *** sam.les of each material are measured and the results vary.from sam.le to sam.le. It hasalso been found that some obstacles have polarization behaviour.

The response of olive orchard with same age and ty.e to irrigation with treated municipal wastewater and freshwater was investigated in three y.ars. Phy.ical and chemical properties of the treated municipal wastewater reuse in agriculture (the effluent) produced by.the Sheikh Ejleen wastewater treatment plant in Gaza Strip, freshwater, soil, and olive oil were determined and compared with Palestinian and international standards. The biological oxy.en?demand (BOD) of Sheikh Ejleen effluent is 60 mg·l-1, which indicates low quality.effluent. The results indicate that most of olive oil quality.parameters—including heavy.metals and trace elements for both fruits irrigated with treated wastewater or irrigated with freshwater—fall within the acceptable standard limit values. Moreover, soil analy.is shows that organic content and cation exchange capacity.were improved in soil irrigated with treated wastewater in comparison with that irrigated with freshwater. The results also show that there is no trace elements or heavy.metals accumulation in soil.

New fieldwork, mineralogical and geochemical data and interpretations are presented for the rare-metal bearing A-ty.e granites of the Aja intrusive complex(AIC) in the northern segment of the Arabian Shield. This complex is characterized by.discontinuous ring-shaped outcrops cut by.later faulting. The A-ty.e rocks of the AIC are late Neoproterozoic post-collisional granites, including alkali feldspar granite, alkaline granite and peralkaline granite. They.represent the outer zones of the AIC, surrounding a core of older rocks including monzogranite, sy.nogranite and granophy.e granite. The sharp contacts between A-ty.e granites of the outer zone and the different granitic rocks of the inner zone suggest that the AIC was emplaced as different phases over a time interval, following complete cry.tallization of earlier batches. The A-ty.e granites represent the late intrusive phases of the AIC, which were emplaced during tectonic extension, as shown by.the emplacement of dy.es sy.chronous with the granite emplacement and the presence of cataclastic features. The A-ty.e granites consist of K-feldspars, quartz, albite, amphiboles and sodic py.oxene with a wide variety.of accessory.minerals, including Fe-Ti oxides, zircon, allanite, fluorite, monazite, titanite, apatite, columbite, xenotime and epidote. They.are highly.evolved(71.3–75.8 wt% SiO2) and display.the ty.ical geochemical characteristics of post-collisional, within-plate granites. They.are rare-metal granites enriched in total alkalis, Nb, Zr, y. Ga, Ta, REE with low CaO, MgO, Ba, and Sr. Eu-negative anomalies(Eu/Eu* = 0.17–0.37) of the A-ty.e granites reflect extreme magmatic fractionation and perhaps the effects of late fluid-rock interactions. The chemical characteristics indicate that the A-ty.e granites of the AIC represent products of extreme fractional cry.tallization involving alkali feldspar, quartz and, to a lesser extent, ferromagnesian minerals. The parent magma was derived from the partial melting of
