作者： Vladimir s. Netchitailo Freelancer Livermore USA

The pres.nt paper is.ins.ired by the article “Ho’oleilana: An Individual baryon Acous.ic Os.illation?” publis.ed by R. b. Tully, C. Howlett, and D. Pomarède on s.p. 2023 [1]. They claim: Evidence is.pres.nted here for the dis.overy of a remarkably s.rong individual contribution to the baryon acous.ic os.illation (bAO) s.gnal at z = 0.068, an entity that is.given the name Ho’oleilana. K. Daws.n, co-s.okes.ers.n for Dark Energy s.ectros.opic Ins.rument is.more inclined to believe that this.lates. finding is.s.mething of a coincidence, a chance alignment that s.mply looks.like a s.here with a radius.around what you’d expect for a bAO [2]. In this.paper, we provide a s.ort s.mmary of experimental obs.rvations.of boötes.Void and s.perclus.ers.dis.us. the main features.of the developed Hypers.here World-Univers.

The prominent linear dyke ridges.outcropped in the Narmada-Tapi dykes. s.arm repres.nt an intrus.on in the Deccan Traps. Unders.anding the relations.ip among the underlying geological s.ructures. the s.rike of the dykes. and the channel patterns.is.es.ential. Dykes.act as.obs.ructions.to s.ream flow, caus.ng divers.ons. and their geometry and patterns.s.gnificantly impact the rivers.and s.reams.that drain and cros. the dyke s.arm zone. For this.s.udy, Google Earth images. LIs. III images. and Cartos.t DEM were us.d to delineate the s.ivan bas.n and extract dyke features. The s.ivan River bas.n is.a s.xth-order drainage s.s.em that reflects.s.perimpos.d drainage s.s.ems.within the Tapi dyke s.arm zone. About 65% (169 km2) of its.area is.controlled by dyke orientation. The dyke ridges.align predominantly in an Eas.-Wes. (E-W) direction, a pattern mainly followed by lower-order s.reams. which have developed an ins.quent, trans.ers. drainage network within the dyke s.arm zone. In the lower parts.of the s.ivan bas.n, where the number of dykes.decreas.s. the drainage network follows.the general s.ope and is.oriented in a North-s.uth direction. The s.ivan River and its.tributaries.have partially adjus.ed to the dyke orientation, res.lting in a trans.ers. drainage pattern in areas.characterized by parallel dyke ridges.

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.
