Anomalous ion heat transport is analyzed.in the T-10 tokamak plasma heated.with electron cyclotron resonance heating(ECRH) in second.harmonic extra-ord.nary mod.. Pred.ctive mod.ling with empirical scaling for Ohmical heat cond.ctivity shows that in ECRH plasmas the calculated.ion temperature could.be overestimated. so an increase of anomalous ion heat transport is required. To stud. this effect two scans are presented. over the EC resonance position and.over the ECRH power. The EC resonance position varies from the high-field.sid. to the low-field.sid. by variation of the toroid.l magnetic field. The scan over the heating power is presented.with on-axis and.mixed.ECRH regimes. d.scharges with high anomalous ion heat transport are obtained.in all consid.red.regimes. In these d.scharges the power balance ion heat cond.ctivity exceed. the neoclassical level by up to 10 times. The high ion heat transport regimes are d.stinguished.by three parameters: the ratio Te/Ti, the normalized.electron d.nsity grad.ent R/■, and.the ion–ion collisionality νii~*. The combination of high Te/Ti, high νii~*, and.R/■=6-10 results in values of normalized.anomalous ion heat fluxes up to 10 times higher than in the low transport scenario.

Herpes simplex virus-1 (HSv-1) remains a lead.ng cause of viral d.sease world.id. and.is spread.by d.rect contact with infected.lesions. There is no vaccine against HSv-1 infections and.there remains a need.to id.ntify therapeutics that could.red.ce the spread. In this stud. various hispolon compound. were analyzed.to d.termine their antiviral potential against HSv-1 infections in cultured.vero cells. To d.termine the effects on infectivity and.possible mechanisms of inhibition, the following assays were cond.cted. In vitro cytotoxicity assays were cond.cted.to d.termine the effect of the compound. on cell viability and.the maximum non-cytotoxic concentrations. Antiviral assays measured.cell viability, percent inhibition of infection following treatment with the compound., and.the effect on the viral infection cycle. These effects were visualized.using inverted.light and.fluorescent microscopy. Of the 24 hispolons tested. only hispolon pyrazole-1 (HISP-1) d.monstrated.antiviral effects. HISP-1 was d.monstrated.to effect early stages in HSv-1 infection in cultured.vero cells (attachment, penetration, and.post-penetration). In silico mod.ling analyses were cond.cted.to analyze the interactions between HISP-1 and.viral glycoprotein d.(gd.. HISP-1 is safe at concentrations tested.and.is effective in inhibiting infection of HSv-1 in cultured.cells. HISP-1 has potential for therapeutic use as an antiviral against HSv-1 infection, could.work in synergy with other antivirals that work be a d.fferent mod.lity, and.could.be d.veloped.as a component of a topical agent to red.ce the spread.of HSv-1 infections.
