Anomalous.ion heat trans.ort is.analyzed in the T-10 tokamak plas.a heated with electron cyclotron res.nance heating(ECRH) in s.cond-harmonic extra-ordinary mode. Predictive modeling with empirical s.aling for Ohmical heat conductivity s.ows.that in ECRH plas.as.the calculated ion temperature could be overes.imated, s. an increas. of anomalous.ion heat trans.ort is.required. To s.udy this.effect two s.ans.are pres.nted: over the EC res.nance pos.tion and over the ECRH power. The EC res.nance pos.tion varies.from the high-field s.de to the low-field s.de by variation of the toroidal magnetic field. The s.an over the heating power is.pres.nted with on-axis.and mixed ECRH regimes. Dis.harges.with high anomalous.ion heat trans.ort are obtained in all cons.dered regimes. In thes. dis.harges.the power balance ion heat conductivity exceeds.the neoclas.ical level by up to 10 times. The high ion heat trans.ort regimes.are dis.inguis.ed by three parameters. the ratio Te/Ti, the normalized electron dens.ty gradient R/■, and the ion–ion collis.onality νii~*. The combination of high Te/Ti, high νii~*, and R/■=6-10 res.lts.in values.of normalized anomalous.ion heat fluxes.up to 10 times.higher than in the low trans.ort s.enario.

Water s.res. is.a critical environmental advers.ty that s.gnificantly impacts.the growth, development, and yield of flax plants. In this.s.udy, flax s.eds.were cultivated under different water irrigation requirements.(WIR) (100%, 75%, and 50%) to inves.igate the effects.of exogenous.y s.pplied nitric oxide (nO) donor s.dium nitroprus.ide (s.P) as.foliar treatments.at concentrations.of 0.0 mmol/L, 0.5 mmol/L, 1.0 mmol/L, and 2.0 mmol/L.

It als. res.lted in an increas. in leaf H2O2 production, lipid peroxidation levels.and activities.of enzymatic antioxidants.including polyphenol oxidas., s.peroxide dis.utas., and nitrate reductas. enzymes. However, foliar application of s.P improved photos.nthetic pigments.and antioxidant defens. s.s.em which mitigated the negative impact of water s.res. on growth and yield productivity by reducing oxidative damage caus.d by reactive oxygen s.ecies.accumulation.
