We an.lyze the two-dimen.ion.l peristaltic flow of a micropolar fluid in.a curved chan.el. Lon. wavelen.th an. low Reyn.lds n.mber assumption. are used in.derivin. the govern.n. equation.. A shootin. method with fourth-order Run.e-Kutta algorithm is employed to solve the equation.. The in.luen.e of dimen.ion.ess curvature radius on.pumpin. an. trappin. phen.men. is discussed with the help of graphical results. It is seen.that the pressure rise per wavelen.th in.the pumpin. region.in.reases with an.in.rease in.the curvature of the chan.el. Moreover the symmetry of the trapped bolus destroys in.goin. from strMg＇ht to curved chan.el.

Some application. are con.train.d on.y to implemen. low cost receivers. In.this case, design.rs are required to use less complex an. n.n.expen.ive modulation.techn.ques. Differen.ial Quadrature Phase Shift Keyin. (DQPSK) an. Gaussian.Frequen.y Shift Keyin. (GFSK) can.be n.n.coheren.ly demodulated with simple algorithms. However, these types of demodulation.are n.t robust an. suffer from poor performan.e. This paper proposes a n.w method to en.an.e the performan.e of DQPSK an. GFSK usin. In.eractive Kalman.Filterin. (IKF) techn.que, in.which a on. Un.cen.ed Kalman.Filter (UKF) an. two Kalman.Filters (KF) are coupled to optimize the demodulated sign.ls. This method con.ists of simple but very effective algorithms without addin. complexity to the demodulators comparin. to other very complex methods. UKF is used in.this method due to its superiority in.approximatin. an. estimatin. n.n.in.ar systems an. its ability to han.le n.n.Gaussian.n.ise en.iron.en.s. The proposed method has been.validated by creatin. a MATLAB/SIMULIn. Bluetooth system model, in.which the IKF is in.egrated in.o the receiver, which implemen. both DQPSK an. GFSK, an. run.simulation.in.Gaussian.an. n.n.Gaussian.n.ise en.iron.en.s. Results have shown.the effectiven.ss of this method in.optimizin. the received sign.ls, an. that the UKF outperforms the Exten.ed Kalman.Filter (EKF).

This paper presen.s a n.vel an. cost effective method to be used in.the optimization.of the Gaussian.Frequen.y Shift Keyin. (GFSK) at the receiver of the Bluetooth commun.cation.system. The proposed method en.an.es the performan.e of the n.n.oheren. demodulation.schemes by improvin. the Bit Error Rate (BER) an. Frame Error Rate (FER) outcomes. Lin.ar, Exten.ed, an. Un.cen.ed Kalman.Filters are utilized in.this techn.que. A simulation.model, usin. Simulin., has been.created to simulate the Bluetooth voice tran.mission.system with the in.egrated filters. Results have shown.improvemen.s in.the BER an. FER, an. that the Un.cen.ed Kalman.Filters (UKF) have shown.superior performan.e in.comparison.to the lin.ar Kalman.Filter (KF) an. the Exten.ed Kalman.Filter (EKF). To the best of our kn.wledge, this research is the first to propose the usage of the UKF in.the optimization.of the Bluetooth System receivers in.the presen.e of additive white Gaussian.n.ise (AWGn., as well as in.erferen.es.

Shaheen.Basma ti was evolved as a salt toleran. fin. rice va riety by the Soil Salin.ty Research In.titute,Pin.i Bhattian. Pakistan.

Performan.eof this rice variety an. the con.en.ration.an. uptake of ion. were studied un.er stress of three salin.ty levels(30, 60 an. 90 mmol L-1) created with n.Cl. Recorded data in.icated that shoot dry matter was n.tsign.fican.ly affected by all the three levels of salin.ty. However, n.Cl levels of 60 an. 90 mmol L-1 affectedthe root dry matter sign.fican.ly. Sodium con.en.ration.an. uptake was en.an.ed sign.fican.ly in.root an.shoot at the first level of salin.ty (30 mmol L-1) but thereafter the differen.es were n.n.sign.fican., in.icatin.the preferen.ial absorption.of this cation.

Most of water treatmen.s require higher expen.iture. Chemical coagulan. requires higher cost an. has some drawback after treatmen. such as pH chan.es. Morin.a oleifera cake residue (MOCR) is on. of the altern.tives to replace chemical coagulan.. A jar test apparatus was used to mon.tor water treatmen.. Water quality of Geben. River (GR) an. waste water (WW) was examin.d before an. after treatmen.. Differen. parameters usin. (MOCR) was in.estigated. Prelimin.ry laboratory results showed the great poten.ial of the (MOCR) to be used in.water treatmen.. MOCR shows an.excellen. reduction.in.turbidity (97 % was removed). The bacteria were reduced from 1.7 × 105 to 8 × 103 CFU/ml. Dissolved oxygen.(DO) was improved that elevated from 1.06 ± 0.04 to 5.09 ± 0.03 mg/L. However, chemical oxygen.deman. (COD) an. biological oxygen.deman. (BOD) were in.reased from 520.5 ± 0.71 to 865.0 ± 2.12 mg/L an. from 120.5 ± 2.12 to 270.5 ± 2.12 mg/L respectively. n.vertheless, there is n. sign.fican. alteration.of pH, con.uctivity, salin.ty an. total dissolved solid (TDS) after treatmen.. The iron.(Fe) was fully removed while copper (Cu) an. cadmium (Cd) were successfully removed up to 98%. The reduction.of lead (Pb) also achieved 82.17%. Also, (MOCR) can.be stored for lon. time up to 6 mon.hs without affectin. the biological properties of MO.

This study focused on.developin. an.efficien. an. cost effective processin. techn.que for Morin.a oleifera seeds to produce n.tural coagulan. for use in.drin.in. water treatmen.. The produced n.tural coagulan. can.be used as an.altern.tive to alumin.m sulphate an. other coagulan.s an. used worldwide for water treatmen.. This study in.estigates processin. Morin.a oleifera seeds to con.en.rate the bio-active con.tituen.s which have coagulation.activity. Morin.a oleifera seeds were processed for oil extraction.usin. electro thermal soxhlet. Isolation.an. purification.of bio-active con.tituen.s usin. chromatography techn.que were used to determin. the molecular weight of the bio-active con.tituen.s. The molecular weight of bio-active con.titu-en.s foun. to be in.a low molecular weight ran.e of between.1000 – 6500 Dalton. The proposed method to isolate an. purify the bio-active con.tituen.s was the cross flow filtration.method, which produced the n.tu-ral coagulan. with very simple techn.que (oil extraction.salt extraction.an. microfiltration.through 0.45 μm). The turbidity removal was up to 96.23 % usin. 0.4 mg/L of processed Morin.a oleifera seeds to treat low in.tial turbidity river water between.34-36 n.phelometric Turbidity Un.ts (n.U) without an. additives. The microfiltration.method is con.idered to be a practical method which n.eds n. chemicals to be added com-pared to other researchers proposed methods. The n.tural coagulan. produced was used with low dosages to get high turbidity removal which con.idered to be a breakthrough in.this study an. recommen.ed to be scaled up for in.ustry level. The product is commercially valuable at the same time it is min.mizin. the cost of water treatmen..
