Objective: To iden.ify the phytochemical compoun.s from An.on. muricata(A. muricata) an. to determin. their in.vitro an.i-proliferative activities again.t breast can.er cells, MCF7 an. MDA-MB-231. Methods: A. muricata leaves were successively extracted by soxhlet method usin. n.hexan., ethyl acetate an. methan.l, an. decocted with water. Each extract was an.lysed by gas chromatography mass spectrometry(GCMS) an. characterized with Wiley an. n.ST library searches. An.i-proliferative activity of each extract was evaluated on.MCF7 an. MDA-MB-231 breast can.er cells usin. MTT assay. Results: The GCMS an.lysis of differen. solven. extracts of A. muricata leaves showed presen.e of differen. chemical groups of compoun.s such as steroids, terpen.ids, phen.lic compoun.s, sugars, sugars alcohol an. others in.ludin. vitamin.E. Ethyl acetate leaves extract exhibited the lowest IC_(50) value on.the MDA-MB-231 breast can.er cell an. n.hexan. leaves extract showed the the lowest IC_(50) value on.the MCF-7 breast can.er cell. Con.lusion. Steroids an. phen.lic compoun.s were the main.phytocompoun. groups iden.ified from all A. muricata leaves extracts. The an.iproliferative activity of n.hexan. an. ethyl acetate extract towards breast can.er MCF7 an. MDA-MB-231 respectively might be due to the presen.e of biologically active compoun.s in.the extracts, hen.e, providin. some scien.ific eviden.es of the effectiven.ss of its tradition.l usages.

Highly repeatable multilevel bipolar resistive switchin. in.Ti/Ce Ox/Pt n.n.olatile memory device has been.demon.trated. X-ray diffraction.studies of Ce O2 films reveal the formation.of weak polycrystallin. structure. The observed good memory performan.e, in.ludin. stable cyclin. en.uran.e an. lon. data reten.ion.times（〉10^4s） with an.acceptable resistan.e ratio（～10^2）, en.bles the device for its application. in.future n.n.volatile resistive ran.om access memories（RRAMs）. Based on.the un.que distribution.characteristics of oxygen.vacan.ies in.Ce Ox films, the possible mechan.sm of multilevel resistive switchin. in.Ce Ox RRAM devices has been.discussed. The con.uction.mechan.sm in.low resistan.e state is foun. to be Ohmic due to con.uctive filamen.ary paths, while that in.the high resistan.e state was iden.ified as Ohmic for low applied voltages an. a space-charge-limited con.uction.domin.ted by Schottky emission.at high applied voltages.

Lateral migration.of the Bhagirathi River temporally creates un.voidable geomorphic hazards in.West Ben.al, In.ia. The Bhagirathi River flows SW for ～67.30 km between.the con.luen.e poin. of Ajay an. Jalan.i rivers in.East Burdwan.an. n.dia districts of West Ben.al. The course of Bhagirathi is n.tably migration.pron. an. cultivates problematic chan.es alon. its course over time. In.the study, we have looked in.o its migration.ten.en.y an. un.redictability for past 238 years an. then.predicted the lateral shiftin. of river cen.erlin. usin. temporal satellite imageries – Lan.sat-5(TM) of 1987(8, December), 1995(28, Jan.ary), 2005(7, Jan.ary) an.

Other highlights are the quest of fluvial features, oxbow lakes, mid-chan.el bars, chan.el migration.rate, mean.er geometry, chan.el sin.osity in.differen. parts of river course an. the parts that experien.e in.en.ive ban. erosion. The en.ire river course has been.subdivided in.o three segmen.s; viz. reaches A, B an. C. In.estigation.displays that degree of sin.osity decreases from its an.erior course(1968) to the existin. course(2017). Reach-specific outputs display that reach B is highly sin.ous(SI value 1.94 in.2017) an. SI in.reases temporarily, whereas for reaches A an. C it decreases with time. The rate of migration.is higher in.reach B than.that in.reaches C an. A.

A study has been.con.ucted on.the status of water quality in.two disused man.made lakes, which have poten.ial for cage aquaculture project. This study highlights the quality of water an.lyzed with referen.e to various physical-chemical parameters in.two selected lakes an. their suitability for fish farmin.. A n.mber of parameters were measured in.ludin. the amoun. of n._ 3 -n. n._ 3 -n. n._ 2 -n.an. total phosphorus while in.situ measuremen. in.ludin. DO, pH, temperature, con.uctivity, TDS an. Secchi disk visibility. Beside the physical-chemical of water, the location. morphometry an. climate con.ition. were also in.estigated. The chemical data an.lyzed for six mon.hs in.icated that Lake A an. Lake B are characterized by relatively high DO, slightly n.utral pH an. low TSS. The con.en.ration.of n._ 3 -n.an. n._ 2 -n.was very low (0.058 mg/L an. 0.04 mg/L, respectively) an. total phosphorus was usually in.low con.en.ration.an. sometimes would seem n.gligible. Besides, n._ 3 -n.occurred in.slightly higher con.en.ration.( 1.75 mg/L ). Results obtain.d in.icated that the study site has high poten.iality for developmen. of in.an. fisheries practices.
