Green.method for preparation.of ion.con.uctin. membran.s(ICM) based on.bacterial cellulose n.n.fibers(Cn.) modified by a copolymer of sodium acrylate an. 2-acrylamido-2-methylpropan.sulfon.c acid was elaborated. FTIR an. n.R data con.irmed graftin. of polyacrylate on.o cellulose surface. Formation.of porous structure of the ICM was con.rolled by SEM an. AFM. The maximal ion.c con.uctivity of the membran.s reaches 1.5 an. 3.1 mS·cm^(-1)(60 ℃ an. 98% relative humidity) when.they are saturated with water or H_2SO_4(1 mol·L^(-1)) electrolyte,respectively. Prepared ICM was tested as a separator in.a symmetrical supercapacitor with electrodes based on.polyan.lin. hydrogel. The assembled cell demon.trate ability to operate at high curren. den.ity up to 100 A·g^(-1) main.ain.n. specific capacitan.e 165 F·g^(-1). Maximal specific capacitan.e of 289 F·g^(-1) was achieved at curren. den.ity 1 A·g^(-1). Retain.n. of 90% of in.tial capacitan.e after 10000 of charge-discharge cycles proves high electrochemical stability of prepared ICM.

This study provides n.w in.ights in.o the n.ture of season.l variation. in.coordin.te time series of GPS sites located n.ar active faults an. methods of their modelin.. Mon.hly averaged coordin.te time series were an.lyzed for several pairs of collocated GPS sites situated n.ar the active fault in.ersection.area, in.close proximity to the cen.ral part of the n.rthern.boun.ary of the Amurian.plate an. the vicin.ty of the San.An.reas Fault zon.. It is con.luded that the observed season.l variation. are best described by a breather fun.tion.which is on. of the solution. of the well-kn.wn.sin.-Gordon.equation. The obtain.d results suggest that, in.this case, the source of season.l variation. may be caused by the appearan.e of solitary strain.waves in.the fault in.ersection.system, which may be qualitatively treated as stan.in. waves of compression.exten.ion.of the geological medium. Based on.statistical testin., the limits of applicability of the suggested model have been.established.
