A study was c.nduc.ed i. 2007/2008 at Absela loc.li.y, Banja Shi.udad Di.tri.0} of the Amhara Nati.nal Regi.nal State, Ethi.pi. to evaluate the effec.s of soi. bunds stabi.i.ed wi.h veti.er grass （i.. zi.ani.i.es） and tree luc.rne （c. palmensi.） on soi. physi.0}l and c.emi.0}l properti.s, bund hei.ht, i.ter-terrac. slope and barley （Hordeum vulgare L.） yi.ld. Data were analyzed usi.g one-way analysi. of vari.nc. （ANOVA） and mean values for the treatments were separated usi.g Dunc.n＇s Multi.le Range Test. Results i.di.0}ted that the non-c.nserved fi.lds had si.ni.i.0}ntly （p 〈 0.05） lower organi.0}c.rbon and was found to c.ntai. 66% less OM from the average of the c.nserved treatment. 9-year old sole soi. bund, the 9-year old soi. bund stabi.i.ed wi.h tree luc.rne, the 9-year old soi. bund stabi.i.ed wi.h veti.er, and the 6-year old soi. bund stabi.i.ed wi.h tree luc.rne had 71.20, 68.56, 52.30, and 36.12%, respec.i.ely hi.her perc.nt OM than the c.ntrol treatment. The trend was si.i.ar for total ni.rogen. The non-c.nserved treatment had a hi.her bulk densi.y when c.mpared to the c.nserved fi.lds. Fi.lds wi.h soi. bunds stabi.i.ed wi.h veti.er grass had the hi.hest bund hei.ht and the lowest i.ter-terrac. slope than fi.lds treated wi.h the rest of remai.i.g c.nservati.n measures. Barley grai. yi.lds were si.ni.i.0}ntly （P 〈 0.05） greater i. both the soi. ac.umulati.n and loss zones of the c.nserved fi.lds than the non-c.nserved （c.ntrol） treatment. Prac.i.0}ng soi. c.nservati.n measures and c.rtai.i.g c.uses of land degradati.n c.uld i.prove the soi. physi.0}l and c.emi.0}l properti.s thereby i.c.ease land produc.i.i.y of the c.nserved land.

A method based on the c.mbi.ati.n of the （u,p） formulati.n and fi.i.e element method was appli.d to c.lc.^ati.g the ac.ust^c. performanc. of a double-wall ac.i.e ac.usti.0}struc.ure wi.h porous materi.ls. The （u, p） formulati.n based on the di.plac.ment i. soli. phase and the pressure i. flui. phase was developed to i.vesti.ate the sound propagati.n i. porous materi.ls. The ac.usti.0}performanc. of the double-wM1 ac.i.e ac.usti.0}struc.ure havi.g porous materi.ls was c.lc.lated and the measurement was taken. The numeri.0}l results matc.ed well wi.h the measured data. More than 10 dB transmi.si.n loss of the double-wall ac.i.e ac.usti.0}struc.ure c.n be i.proved i. the resonanc. frequenc. wi.h ac.i.e c.ntrol, and i.s absorpti.n c.effi.0}ent i. up to 0.6 over 500 Hz.
