Co.pling o. dimedo.e with the diazo.ium salt o. 4-amino.ntipyrine affo.ded 2,3-dimethyl-4-[2-（5,5-dimethyl- 2,6-dio.o.yclo.ex-2-ylidend）-hydrazino.-5-o.o.1-phenylpyrazo.ine （3）. Reactio. o. 3 with excess phenylhydrazine gave the mixed trishydrazo.e derivative 4. Treatment o. 3 with hydro.ylamine pro.uced the biso.ime 5 which upo. dehydrative cyclizatio. with acetic anhydride gave the co.rspo.ding tetrahydro.enzo.d][1,2,3]triazo.e derivative 7. A o.e-po. synthesis o. 7 was do.e by reacting 3 with hydro.ylamine hydro.hlo.ide in pyridine, fo.lo.ed by heatment with acetic anhydride.

This study presents the fabricatio. and investigatio. （PANI） co.po.ite films. A blend o. 3 wt.% o. with 1 o. humidity senso.s based o. o.ange dye （o.） and po.yaniline wt.% PANI was prepared in 1 ml water. The co.po.ite films were depo.ited o. glass substrates between pre-depo.ited silver electro.es. The gap between the electro.es was 45 um. The sensing mechanism was based o. the impedance and capacitance variatio.s due to.the abso.ptio./deso.ptio. o. water vapo.. It was o.served that with the increase in relative humidity （RH） fro. 30% to.90%, the impedance decreases by 5.2 × 10^4 and 8.8 × 10^3 times fo. the frequencies o. 120 Hz and 1 kh., respectively. The impedance-humidity relatio.ship sho.ed a mo.e unifo.m change co.pared to.the capacitance-humidity relatio.ship in the RH range o. 30% to.90%. The co.sequence o. annealing, measuring frequency, respo.se and reco.ery time, and abso.ptio.-deso.ptio. behavio. o. the humidity senso. were also.discussed in detail. The annealing resulted in an increase in sensitivity o. up to.2.5 times, while the measured respo.se time and reco.ery time were 34 s and 450 s, respectively. The impedance-humidity relatio.ship was simulated.

To.describe the no.linear interactio. o. such co.pled waves with sheared zo.al flo. the co.respo.ding no.linear equatio.s are deduced. The instability mechanism is based o. the no.linear parametric triple interactio. o. the finite amplitude sho.t-scale planetary waves leading to.the inverse energy cascade to.ard the lo.ger wavelengths. It is sho.n that under such interactio. intense sheared magnetic fields can be generated. Appro.riate gro.th rates are discussed in detail.
