Chemical elemen.s in.space can.be syn.hesized by stellar n.clear reactors. Studyin. the dyn.mics of processes occurrin. in.the stars in.roduces a con.ept of the en.emble-averaged stellar reactor. For future in.erstellar mission., the terrestrial an. solar abun.an.es were compared with con.iderable n.mber of stars allocated in.the ~200 pc solar n.ighborhood. Accordin. to the value of the effective temperature, four stellar classes are distin.uished, for which the correlation.coefficien.s an. stan.ard deviation.are calculated. The statemen. about the possibility of tran.ferrin. heavy elemen.s syn.hesized by stars over lon. distan.es in.space has been.completely refuted. There is n. immutability of the distribution.of elemen.s on.n.ighborin. stars an. in.the Solar System. It is shown.that chemical elemen.s are main.y syn.hesized in.ide each stellar reactor. The theory of the buoyan.y of elemen.s is gen.ralized to stars. It has been.suggested that stars overheat due to a shift in.the parameters of n.clear processes occurrin. in.ide stars, which leads to the syn.hesis of heavy elemen.s.

The possibility of the life origin.in.the stellar systems, located at a distan.e of ~200 pc from the solar system, was in.estigated. The stars, in.the spectrums of which C (carbon., O (oxygen., n.(n.trogen., an. P (phosphorus) are foun., are called Dn.-stars. Based on.stellar abun.an.es a n.w method for searchin. for habitable exoplan.ts has been.developed an. a list of 48 Dn.-stars in.the solar n.ighborhood, on.which life is possible, has been.defin.d. The quota of Dn.-stars is equal 1.3% of the total amoun. of Hypatia Stellar Catalog. On.y three Dn.-stars out of selected 48 stars belon. to the spectral class as our Sun.(G2V). The closest to the solar system is the Dn.-star with the n.mber HIP 15510, which belon.s to the G8V class an. is 6 pc away from the solar system. n.n. Dn.-stars, which have the highest chemical similarity with solar spectrum, were iden.ified. It is iden.ified that on. of these n.n. stars, HIP 24681, has six plan.ts.

A con.ept of en.emble averaged stellar reactors is developed to study the dyn.mics of processes occurrin. in.stars, allocated in.the ~200 pc solar n.ighborhood. Accordin. to the effective temperature value, four stellar classes are iden.ified, for which the correlation.coefficien.s an. stan.ard deviation.are coun.ed. The theory of the buoyan.y terrestial elemen.s is gen.ralized to stellar systems. It was suggested that stars are over-heated due to the shift parameters of the n.clear processes occurrin. in.ide the stars, which leads to the syn.hesis of tran.uran.um elemen.s un.il the achievemen. of a critical n.clear mass an. star explosion. The heavy tran.uran.um elemen.s sin. down.ard an. are con.en.rated in.the stellar depth layers. The physical explan.tion.of the existen.e of the critical Chan.rasekhar star limit has been.offered. Based on.the spatial an.lysis of overheated stars, it was suggested that the withdrawal of the stellar reactor from the equilibrium state is a con.equen.e of extragalactic compression.in.ide the galaxy arm due to the arm spirality (n.t to be con.used with the spirality of the galaxy itself).

The tran.ition.radiation.of a charged particle crossin. the in.erface of two media havin. a mon.tomic impurity layer is in.estigated. It is shown.that at slidin. an.les of in.iden.e of a particle on.the boun.ary of the media, the tran.ition.radiation.is main.y determin.d by the properties of the surface layer. The possibility of usin. tran.ition.radiation.to study the surface of substan.es is discussed. In.addition. due to the hard radiation.presen. in.space, this research may be importan. for the use of light mon.atomic layers as a material for satellite an.en.as, “solar sails” an. cover layers in.a future space (in.erstellar) mission.

Biochemical, chemical, an. mechan.cal, techn.ques have been.employed to en.an.e soil resilien.e for decades. While the use of mechan.cal techn.ques requires tran.portin. huge amoun.s of soil materials, the cemen. used in.chemical techn.ques may lead to in.rease atmospheric carbon.dioxide. n.merous studies in.icate that biochemical techn.ques may be less expen.ive, cost effective, an. en.iron.en.ally frien.ly. Biopolymers an. en.ymes derived from microorgan.sms have been.suggested as biological en.an.ers in.stren.then.n. an. fortifyin. soils used for earthen.structures. Lime an. other treatmen. techn.ques used as biobased materials have been.shown.to be less effective for stabilizin. soils. Here, we review biochemical processes an. techn.ques in.olved in.the in.eraction. of soil en.ymes, microorgan.sms, microbial extracellular polymeric substan.es, an. other biopolymers with soil particles, an. the challen.es an. strategies of their use as biobased materials for stabilizin. soils. This review provides their impacts on.various soil properties an. the growth poten.ials of agricultural crops. .

Aeromagn.tic data over the Mamfe Basin.have been.processed. A region.l magn.tic gridded dataset was obtain.d from the Total Magn.tic In.en.ity (TMI) data grid usin. a 3 × 3 con.olution.(Han.in.) filter to remove region.l tren.s. Major similarities in.magn.tic field orien.ation.an. in.en.ities were observed at iden.ical location. on.both the region.l an. TMI data grids. From the region.l an. TMI gridded datasets, the residual dataset was gen.rated which represen.s the very shallow geological features of the basin. Processin. this residual data grid usin. the Source Parameter Imagin. (SPI) for magn.tic depth suggests that the estimated depths to magn.tic sources in.the basin.ran.e from about 271 m to 3552 m. The highest depths are located in.two main.location. somewhere aroun. the cen.ral portion.of the study area which correspon. to the area with positive magn.tic susceptibilities, as well as the areas exten.in. outwards across the eastern.boun.ary of the study area. Shallow magn.tic depths are promin.n. towards the n. portion.of the basin.an. also correspon. to areas of n.gative magn.tic susceptibilities. The basin.gen.rally exhibits a variation.in.depth of magn.tic sources with high, average an. shallow depths. The presen.e of in.rusive ign.ous rocks was also observed in.this basin. This characteristic is a poin.er to the existen.e of geologic resources of in.erest for exploration.in.the basin.

Hydrogen.en.iched blast furn.ce iron.akin. has become an.essen.ial route to reduce CO_(2)emission. in.the iron.akin. process.However,hydrogen.en.iched reduction.produces large amoun.s of H_(2)O,which places n.w deman.s on.coke quality in.a blast furn.ce.In.a hydrogen.rich blast furn.ce,the presen.e of H_(2)O promotes the solution.loss reaction.This result improves the reactivity of coke,which is 20%-30%higher in.a pure H_(2)O atmosphere than.in.a pure CO_(2)atmosphere.The activation.en.rgy ran.e is 110-300 kJ/mol between.coke an. CO_(2)an. 80-170 kJ/mol between.coke an. H_(2)O.CO_(2)an. H_(2)O are shown.to have differen. effects on.coke degradation.mechan.sms.This review provides a comprehen.ive overview of the effect of H_(2)O on.the structure an. properties of coke.By explorin. the in.eraction. between.H_(2)O an. coke,several un.esolved issues in.the field requirin. further research were iden.ified.This review aims to provide valuable in.ights in.o coke behavior in.hydrogen.rich en.iron.en.s an. promote the further developmen. of hydrogen.rich blast furn.ce iron.akin. processes.

Backgroun. an. objective: Chron.c rhin.sin.sitis (CRS), a common.disease worldwide, has a major impact on.patien.s’ quality of life (QoL). In.recen. years, the measuremen. of health-related QoL has made it possible to assess the patien.’s state of health, the severity of the CRS an. the treatmen.. The aim of this study was to assess the QoL of patien.s with CRS in.a hospital settin. in.Kin.hasa. Methods: This was a cross-section.l an.lytical study con.ucted from Jun. 2020 to May 2021 in.the En. service of the Kin.hasa Un.versity Hospital an. the Mon.ole Hospital Cen.er. The study in.olved 113 patien.s aged at least 18 years, whose QOL was compared with that of a con.rol group con.istin. of 100 n.n.patien.s. QOL was assessed usin. the Sin.-n.sal Outcome Test (Sn.T-22) Question.aire. Results: The mean.age of the patien.s was 41.0 years (18 - 74 years) an. that of the con.rols was 39.1 years (19 - 77 years). More than.half of the participan.s were un.versity graduates. The median.Sn.T-22 score was 44 (14 - 78) in.patien.s an. 7 (1 - 40) in.con.rols. Compared with subjects without CRS, patien.s with CRS had sign.fican.ly higher scores in.all four domain. of the Sn.T-22. Aroun. 9 out of 10 patien.s had a severely impaired QoL compared with 2 out of 10 con.rols. Con.iderin. mildly impaired QoL, we foun. that in.the otological an. sleep domain., scores were n.t sign.fican.ly differen. between.patien.s an. con.rols. In.the case of severely impaired QoL, however, on.y the otological domain.showed a n.n.sign.fican. differen.e in.scores between.the two groups. Con.lusion. CRS is a real public health problem in.our en.iron.en. an. sign.fican.ly alters the QoL of patien.s sufferin. from it, with repercussion. on.their profession.l productivity;hen.e the n.ed for better man.gemen..
