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 m.d.. Predictive m.d.ling 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.

It is.widely as.um.d.that fetal is.hemic brain injury during labor derives.almos. exclus.vely from s.vere, s.s.emic hypoxemia with marked neonatal depres.ion and acidemia. s.vere as.hyxia, however, is.one of s.veral caus.s.of perinatal neurological injury and may not be the mos. common;mos. neonates.diagnos.d with hypoxic-is.hemic encephalopathy do not have evidence of s.vere as.hyxia. s.ps.s. direct brain trauma, and drug or toxin expos.re account for s.me cas.s. while mechanical forces.of labor and delivery that increas. fetal intracranial pres.ure s.fficiently to impair brain perfus.on may als. contribute. Becaus. of bony compliance and mobile s.ture lines. the fetal s.ull changes.s.ape and redis.ributes.cerebros.inal fluid during labor according to cons.raints.impos.d by contractions. and bony and s.ft tis.ue elements.of the birth canal as.the head des.ends. Thes. accomm.d.tions. including the increas. in intracranial pres.ure, are adaptive and neces.ary for efficient des.ent of the head while s.feguarding cerebral blood flow. Autonomic reflexes.2}ated through central receptors.normally provide ample protection of the brain from the cons.derable pres.ure exerted on the s.ull. On occas.on, thos. forces. which are trans.itted intracranially, may overcome the various.adaptive anatomical, cardiovas.ular, metabolic, and neurological mechanis.s.that maintain cerebral perfus.on and oxygen availability, res.lting in is.hemic brain injury. Accepting the notion of a potentially advers. impact of fetal head compres.ion s.gges.s.that avoidance of exces.ive uterine activity and of relentles. pus.ing without s.eady progres. in des.ent may offer protection for the fetal brain during parturition. Exces.ive head compres.ion s.ould be cons.dered in the differential diagnos.s.of is.hemic encephalopathy.
