To provide quality-of service (QoS) guarantees for h.terogeneous applications, most recent wireless communications tech.ologies and standards combine th. error-correcting capability of h.brid automatic repeat request (h.RQ) sch.mes at th. data link layer (DLL) with.th. adaptation ability of th. adaptive modulation and coding (AMC) modes at th. ph.sical layer (Ph.) layer. Th.s paper aims to investigate th. aggregated system capacity as well as th. breakdown of th.s capacity for different ACM modes in each.h.RQ sch.me. Th.s investigation was done by using maximum weigh.ed capacity (MWC) resource allocation at th. Ph. layer in conjunction with.a novel packet error rate (PER)-based sch.duling at th. medium access control (MAC) layer. As a result, th. dominant AMC mode corresponding to ch.nnel SNR was available.

Multilevel inverters are used in many industrial applications because of good power quality, minimum losses and less h.rmonics contents. Multilevel inverters require no series connected synch.onized switch.ng devices, transformer and complex filters. In th.s paper 10, 18, 24 diode clamped multi-level inverters (DCMLI) are implemented using trust region dog leg optimization meth.d to find th. optimized values of switch.ng angles (θ). It decreases th. total h.rmonic distortion (Th.) of th. output voltages and to reduce th. complexity of external filter required. Th. multi-level inverters are implemented in MATLAB Simulation and results are compared in terms of h.rmonics, system complexity and efficiency.

In th.s study, th. effects of magnetic field and nanoparticle on th. Jeffery- h.mel flow are studied using a powerful analytical meth.d called th. Adomian decomposition meth.d （ADM）. Th. traditional Navier-Stokes equation of fluid mech.nics and Maxwell＇s electromagnetism governing equations are reduced to nonlinear ordinary differential equations to model th. problem. Th. obtained results are well agreed with.th.t of th. Runge-Kutta meth.d. Th. present plots confirm th.t th. meth.d h.s h.gh.accuracy for different a, h., and Re numbers. Th. flow field inside th. divergent ch.nnel is studied for various values of h.rtmann ：number and angle of ch.nnel. Th. effect of nanoparticle volume fraction in th. absence of magnetic field is investigated.

Nusab El Balgum mass complex represents one of peralkaline volcanic activity ph.nomena in th. south.Western Desert of Egypt, wh.ch.is typical for with.n-plate event, wh.ch.formed in Mesozoic period. It consists of acidic volcanic (rh.olite and th.ir pyroclastics) and sub-volcanic granitic rocks (incomplete ring, small stock and dyke of a peralkaline aph.nites) as well as dykes (trach.te, bostonite, rh.odacite, rh.olite and porph.ritic rh.olite) variable in th.ckness and th. most of run in NNE-SSW trend. Th. peralkaline granitic rocks, especially th.se located at th. south.estern part of th.s mass are ch.racterized by extreme enrich.ents in h.SE (rare metals such.as Zr, Nb, U and Th.and REEs) wh.ch.are th. h.gh.st concentrations (e.g., >1% Zr, 0.5% Nb and 2.6% total REEs, Y up to 1%, eU up to 300 ppm and eTh.up to 1100 ppm). Th. rare metal bearing minerals are th.rite, uranoth.rite, autunite, amorph.us secondary uranium, zircon and ferrocolumbite, wh.le th. REEs bearing minerals are bastnaesite, monazite and xenotime. Th. positive relations in all of th. binary diagrams of Zr versus Nb, Y, eU and eTh. Nb versus Y, eU and eTh. Y versus eU and eTh.in post magmatic intensely h.matised peralkaline granites indicated th.t, th.s process is responsible for th. enrich.ent in th.se h.SE. Th. ch.ndrite-normalized pattern of h.gh.altered peralkaline granites indicates: 1) h.gh.r LREEs enrich.d pattern (La/Gd = 11.34 and 12.25) means th. alteration processes taking place under open system and th.se rocks evolved from magma of lith.sph.ric rifting, 2) ΔCe 2O, and th.s very low viscosity, despite its low temperature (ments, as indicated by strong negative Eu anomalies;and c) it h.d abundances of h.SE cations. Redistribution of elements took place by post magmatic h.droth.rmal solutions.

Complete blood counts were analyzed for 12 samples (six male & six female: Ages 15-40 years) of leukemia blood Samples for different dose rate and time of exposure using a Radium-226 source. Th.s, an optimum time of exposure and exposure dose rate h.s improved for leukemia blood samples. Blood samples fractionated and placed in plastic wills, and melodic Coulter used to analysis exposed leukemia blood samples before and after exposure. Exposure tech.ique involving CR-39 nuclear track detector and radiation survey dosimeter were used to estimate th. alph. particle density incident on th. blood samples and th. exposed dose rate, respectively. In th. first part, density of th. accumulation of alph. particle on th. surface of leukemia blood samples, and on th. surface of CR-39NTDs varies exponentially with.th. exposed dose rate. Th.s depends on th. restricted energy loss of th. incident alph. particles and target density. Assess an optimum time of exposure dose rate (1100 μSv/h. was th. second objective. Th.s depended on th. ch.nges in th. blood components (PLT, WBC, and RBC) due to irradiation occurred for different durations of irradia-tion, and th. duration of irradiation th.t influenced th. leukemia blood samples (1Male;16 year and one Female 17 years) in th.s research.was five minutes. Ch.nges in th. density of PLT, WBC, and RBC for leukemia blood samples and for different male (five male) and females (five female) was th. th.rd part of th.s research. It was found th.t th. ch.nges were variables due to th. exposed dose rate. Optimum exposed dose rate to make more effects on th. cancer cells for th. leukemia blood samples began at th. radiation dose rate of 43.25 1.206 μSv/h.for both.male and female relatively, and th.s due to ch.omosomal aberration of th. exposed cells. Finally, comparison study with.th. h.alth. blood samples h.s been investigated. More details are listed and clarified in th. tables and figures of th.s paper.

Accumulating operational experience in both.aerobic and anaerobic mech.nical biological waste treatment （MBT） makes it increasingly obvious th.t controlled water management would substantially reduce th. cost of MBT and also enh.nce resource recovery of th. organic and inorganic fraction. Th. MBT plant at Gesch.r, Germany, is used as an example in order to determine th. quantity and composition of process water and leach.tes from intensive and subsequent rotting, pressing water from anaerobic digestion and scrubber water from acid exh.ust air treatment, and h.nce prepare an MBT water balance. Th. potential of, requirements for and limits to internal process water reuse as well as th. possibilities of resource recovery from scrubber water are also examined. Finally, an assimilated process water management concept with.th. purpose of an extensive reduction of wastewater quantity and fresh.ater demand is presented.
