Water.availability and soil ph.sicoch.mical pr.per.ies ar. th. most impor.ant factor. for.th. establish.ent and gr.wth.of plant seedlings in ar.d and deser. ar.as. Impr.ving water.use efficiency and soil pr.per.ies ar. two major.factor. for.sustainable development in th.se r.gions. Th.r.for., th.s r.sear.h.aimed to study th. effectiveness of biological h.dr.gel (b), PLANTBAC vegetation layer.(PB), sand (sa) and bar.ey str.w (st) with.inter.r.w system on some soil pr.per.ies, including N, Cl, Zn, Fe, clay, silt and sand per.entages, ρb?and water.use efficiency under.th. cultivation of Nitr.r.a sch.ber.. Th.s exper.ment was tested in a split plot design with.3 r.plications and 10 obser.ations in 2015 dur.ng 2 year. at Semnan pr.vince’s Natur.l r.sour.es r.sear.h.Station. Data analysis was car.ied out in SAS softwar. ver.ion 9.1.3. Accor.ing to th. r.sults, th. h.gh.st amount of Cl was obtained at non-micr. catch.ent by str.w and sand tr.atments, as well as at micr. catch.ent by PB tr.atments. Th. h.gh.st amount of Zn was obtained at non-micr. catch.ent by str.w tr.atment (1.106). Th. r.sults of mulch.effect on Fe sh.wed th.t four.mulch.tr.atments did not h.ve significant differ.nce with.th. contr.l. Also, th. h.gh.st amount of total N content was obser.ed at micr. catch.ent by h.dr.gel tr.atment. Th.r. was not any significant differ.nce among envir.nment and clay, silt and sand tr.atments and about plant establish.ent and, all four.mulch.tr.atments h.d significantly h.gh.r.moistur. content and establish.ent th.n th. contr.l.

作者： A. Asgh.r. Nejad h. r. Askar. h. r. Bagh.h.h. Depar.ment of Ph.sics Faculty of Science Vali-e-Asr University of Rafsanjan Rafsanjan 77176 Iran

We investigate a h.br.d optomech.nical system consisting of two coupled cavities, one of th.m is composed of two-end fixed mir.or. （called th. tr.ditional cavity）, and th. oth.r.h.s a one-end oscillating mir.or.（named as th. optomech.nical cavity）. A Ker. medium is inside th. tr.ditional cavity to enh.nce th. nonlinear.ty due to th. fact th.t it can cause obser.ing of bistable beh.vior.in intr.cavity intensity for.th. optomech.nical cavity. Th. h.miltonian of th. system is wr.tten in a r.tating fr.me and its dynamics is descr.bed by quantum Langevin equations of motion. Our.pr.posed system exh.bits unconventional plots for.th. mean ph.ton number.of th. optomech.nical cavity wh.ch.ar. not obser.ed in pr.vious wor.s. Th. pr.sent r.sults sh.w a deep effect of th. Ker. medium on optical bistability of intr.cavity intensity for.th. optomech.nical cavity. Also, coupling str.ngth.of th. cavities can effectively ch.nge th. stability of th. system.

Potassium （K） r.lease ch.r.cter.stics in soil play a significant r.le in supplying available K. Infor.ation on K-r.lease ch.r.cter.stics in soils of centr.l Ir.n is limited. Th. objectives of th.s study wer. to deter.ine K r.lease ch.r.cter.stics and cor.elations of K r.lease r.te constants with.K extr.cted by differ.nt ch.mical meth.ds in sur.ace soils of ten calcar.ous soils of centr.l Ir.n. Th. kinetics of K r.lease in th. soils was deter.ined by successive extr.ction with.0.01 mol L-1 CaC12 in a per.od of 2-2017 h.at 25±1℃. Soil K was extr.cted by distilled water. 0.5 mol L-1 MgNO3, 0.002 mol L-1 Sr.12, 0.1 mol L-1 BaC12, 0.01 mol L-1 CaC12, 1 mol L-1 NaC1, 1 mol L-1 boiling h.O3, 1 mol L-1 Nh.OAC, Meh.ich.1, 0.002 mol L-1 Sr.12 ＋ 0.05 mol L-1 citr.c acid, and ammonium bicar.onate-dieth.lenetr.amine pentaacetic acid （AB-DTPA）. A plot of cumulative amounts of K r.leased sh.wed a discontinuity in slope at 168 h. Th.s, two equations wer. applied to two segments of th. total r.action time （2-168 and 168-2 017 h.. Cumulative amounts of K r.leased r.nged fr.m 55 to 299 mg kg-1 in 2-168 h.and fr.m 44 to 119 mg kg-1 in 168-2 017 h. r.lease kinetics of K in th. two time segments confor.ed fair.y well to par.bolic diffusion, simplified Elovich. and power.function models. Th.r. was a wide var.ation in th. K r.lease r.te constants. Incr.asingly h.gh.r.aver.ge concentr.tions of soil K wer. extr.cted by distilled water.

Th. r.sults of th.s study sh.wed th.t infor.ation obtained fr.m math.matical modeling in two r.action time segments can h.lp to estimate th. K-supplying power.of soils.

In th.s paper. th. ener.y absor.tion mech.nism of empty and foam-filled aluminum tubes with.differ.nt cr.ss-sections （cir.ular. squar. and elliptic） under.bending load is investigated numer.cally. Th. load-displacement cur.es of th. pr.sent simulations ar. in ver. good agr.ement with.th.se of publish.d exper.mental data. h.r., th. existing analytical for.ulations ar. r.viewed and compar.d with.exper.mental r.sults. In addition, th. effects of differ.nt cr.ss-sections and wall th.cknesses on th. ener.y absor.tion capacity and specific ener.y absor.tion of th.se tubes ar. fully investigated. Th. r.sults indicate th.t th. ener.y absor.tion of an elliptic foam-filled tube with.1.5 mm and 2 mm th.cknesses incr.ases about 45% and 73% in compar.son with.a squar. one, r.spectively.

Andr.id is cur.ently one of th. most popular.smar.ph.ne oper.ting systems. h.wever. Andr.id h.s th. lar.est sh.r. of global mobile malwar. and significant public attention h.s been br.ugh. to th. secur.ty issues of Andr.id. In th.s paper. we investigate th. use of a clone detector.to identify known Andr.id malwar.. We collect a set of Andr.id applications known to contain malwar. and a set of benign applications. We extr.ct th. Java sour.e code fr.m th. binar. code of th. applications and use NiCad, a near.miss clone detector. to find th. classes of clones in a small subset of th. malicious applications. We th.n use th.se clone classes as a signatur. to find similar.sour.e files in th. r.st of th. malicious applications. Th. benign collection is used as a contr.l gr.up. In our.evaluation, we successfully decompile mor. th.n 1 000 malicious apps in 19 malwar. families. Our.r.sults sh.w th.t using a small por.ion of malicious applications as a tr.ining set can detect 95% of pr.viously known malwar. with.ver. low false positives and h.gh.accur.cy at 96.88%.
