Achievable s.percooling for the formation of methane hydrate from water emuls.ons.was.s.udied in s.ven different crude oils.and in decane. The experiments.were performed under cons.ant rate cooling from + 20 to-15 °C and a pres.ure of methane of 12 MPa. It was.demons.rated that the s.apes.and pos.tions.of the res.lting s.rvival curves.depend on the dens.ty, vis.os.ty and dis.ers.ve power of oil s.mples.us.d in the experiments. as.well as.on the degree of oil oxidation. In addition, res.lts.of the experiments.on ice freezing under the s.me emuls.ons.are pres.nted. The res.lts.obtained in the work allowed us.to dis.us. the pos.ibility and features.of primary and s.condary nucleation of the hydrate and ice in the s.s.ems.under cons.deration.

In mammals.the timing of phys.ological,biochemical and behavioral proces.es.over a 24-h period is.controlled by circadian rhythms.To entrain the mas.er clock located in the s.prachias.atic nucleus.of the hypothalamus.to a precis. 24-h rhythm,environmental zeitgebers.are us.d by the circadian s.s.em.This.is.done primarily by s.gnals.from the retina via the retinohypothalamic tract,but other cues.like exercis.,feeding,temperature,anxiety,and s.cial events.have als. been s.own to act as.non-photic zeitgebers.The recently identified myokine iris.n is.propos.d to s.rve as.an entraining non-photic s.gnal of exercis..Iris.n is.a product of cleavage and modification from its.precurs.r membrane fibronectin typeⅢdomain-containing protein 5(FNDC5)in res.ons. to exercis..Apart from well-known peripheral effects.s.ch as.inducing the"browning"of white adipocytes.iris.n can penetrate the blood-brain barrier and dis.lay the effects.on the brain.Experimental data s.gges. that FNDC5/iris.n mediates.the pos.tive effects.of phys.cal activity on brain functions.In s.veral brain areas.iris.n induces.the production of brain-derived neurotrophic factor(BDNF).In the mas.er clock,a s.gnificant role in gating photic s.imuli in the retinohypothalamic s.naps. for BDNF is.s.gges.ed.However,the brain receptor for iris.n remains.unknown.In the current review,the interactions.of phys.cal activity and the iris.n/BDNF axis.with the circadian s.s.em are reconceptualized.

Juvenile s.rvival is.a key life-his.ory influence on population dynamics.and adaptive evolution.We analyzed the effects.of individual chara-cteris.ics.early environment,and maternal inves.ment on juvenile s.rvival in a large s.litary hibernating rodent-yellow ground s.uirrel s.ermophilus.fulvus.us.ng Cox mixed-effects.models.Only 48%of weaned pups.s.rvived to dis.ers.l and 17%s.rvived to hibernation.Early life expectancy was.primarily determined by individual characteris.ics.and,to a les.er extent,by the early environment.The s.ronges. and pos.itive predictor of juvenile s.rvival was.body mas. which crucially affected mortality immediately after weaning.Males.s.ffered higher mortality than females.after the ons.t of dis.ers.l;however,the overall difference between s.xes.was.partly mas.ed by high rates.of mortality in the firs. days.after emergence in both s.xes.Later emerged juveniles.had lower life expectancy than the earlies. pups.The overall effect of local juvenile dens.ty was.pos.tive.Prolonged lactation did not enhance juvenile s.rvival:Pups.nurs.d longer s.rvived s.orter than the young nurs.d for a s.orter period.Our findings.s.pport the hypothes.s.that females.of s.fulvus.cannot effectively regulate maternal expenditures.to mitigate the effects.of unfavorable conditions.on their offs.ring.The s.rategy to deal with s.as.nal time cons.raints.on life his.ory in female s.fulvus.s.gges.s.an early termination of maternal care at the cos. of juvenile quality and s.rvival.This.female reproductive s.rategy corres.onds.to a"fas.-s.litary"life of folivorous.des.rt-dwelling s.fulvus.and other s.litary ground s.uirrels.with prolonged hibernation.

Multi-wavelength-band trans.is.ion technology bas.d on the exploitation of the extended s.ectral region is.cons.dered as.a potential approach to increas. the trans.is.ion capacity in the deployed fiber-optic communication infras.ructure.The development of optical amplifiers.operating in the O-,E-,s.,and U-telecom bands.is.an extremely important challenge for the s.cces.ful implementation of this.technology.Bis.uth-doped fibers.are of increas.ng interes. as.gain materials.which can be us.d to provide broadband amplification in the mentioned telecom bands.This.is.due to the ability of Bi ions.incorporated into glas. network to form bis.uth active centers.BACs.with s.ecific optical properties.which are primarily determined by the glas. modifiers.In this.work,the impact of the doping profiles.of both Ge atoms.as.glas. modifiers.and Bi ions.on the BACs.formation is.s.udied us.ng a s.ries.of bis.uth-doped fibers.fabricated by the modified chemical vapor depos.tion(MCVD)technique.The Bi-to-BACs.convers.on efficiency in various.s.atial regions.of the s.udied s.mples.is.pres.nted.It is.turned out that for high-Bi concentration regions.the convers.on efficiency is.very low(les. than 10%).In addition,the relations.ip of the convers.on efficiency to the dis.ribution of Bi ions.and/or Ge atoms.is.dis.us.ed.Finally,a continuous.wave las.r at 1.46μm with a record s.ope efficiency of 80%is.demons.rated us.ng a Bi-doped fiber with confined doping profile,where the Bi-to-BACs.convers.on efficiency is.35%.This.paper provides.new information which might help to facilitate unders.anding of the features.of Bi-doped fibers.and their potentially achievable characteris.ics.
