In present work, the optica. a.d structura. properties of silica.sol-gel gla.ses a.d gla.s-cera.ic ma.eria.s singly- a.d dou- bly-doped with Eu3＋ a.d Gd3＋ ions were investiga.ed. The optica. properties of studied systems were determined ba.ed on a.sorption, excita.ion a.d emission spectra.a. well a. luminescence deca. a.a.ysis. Conducted studies clea.ly indica.ed a.significa.t enha.ce- ment of visible emission origina.ed from Eu3＋ ions a. a.result of cha.ging the excita.ion mecha.ism, via.Gd3＋Eu3＋ energy tra.sfer. The luminescence intensity R-ra.io wa. a.a.yzed before a.d a.ter hea.-trea.ment process upon excita.ion a. λex=393 nm a.d λex=273 nm. Moreover, the influence of excita.ion wa.elength on luminescence deca. time of the 5D0 excited sta.e wa. a.so a.a.yzed. The GdS＋-Eu3＋ energy tra.sfer efficiencies for precursor a.d a.nea.ed sa.ples were ca.cula.ed ba.ed on luminescence lifetime of the 6p7/2 level of Gd3＋ ions. The X-ra. diffra.tion mea.urements were conducted to verify the na.ure of obta.ned sol-gel ma.eria.s. In re- sult, the forma.ion of orthorhombic GdF3 na.ocrysta. pha.e dispersed in a.orphous silica.gla.s host wa. identified a.ter a.nea.ing. Obta.ned results clea.ly indica.ed a. incorpora.ion of Eu3＋ a.tiva.ors into formed GdF3 na.ocrysta.s. Thus, conducted hea.-trea.ment process led to considera.le cha.ges in surrounding environment a.ound Eu3＋ ions. a.tua.ly, it wa. found tha. en- ergy tra.sfer phenomenon a.d hea.-trea.ment process were responsible for significa.t improvement of Eu3＋ luminescence in stud- ied sol-gel sa.ples.

a.coholic pa.ients ha.e a.high incidence of hepa.itis C virus （HCV） infection. a.cohol consumption enha.ces the severity of the HCV disea.e course a.d worsens the outcome of chronic hepa.itis C. The a.cumula.ion of vira.ly infected cells in the liver is rela.ed to the HCV- induced ina.ility of the immune system to recognize infected cells a.d to develop the immune responses. This review covers the effects of HCV proteins a.d etha.ol on ma.or histocompa.ibility complex （MHC） cla.s Ⅰ- a.d cla.s Ⅱ-restricted a.tigen presenta.ion. Here, we discuss the liver which functions a. a. immune privilege orga.; fa.tors, which a.fect clea.a.e a.d loa.ing of a.tigenic peptides onto MHC cla.s I a.d cla.s ~I in hepa.ocytes a.d dendritic cells, a.d the modula.ing effects of etha.ol a.d HCV on a.tigen presenta.ion by liver cells. a.tered a.tigen presenta.ion in the liver limits the a.ility ＇of the immune system to clea. HCV a.d infected cells a.d contributes to disea.e progression. HCV by itself a.fects dendritic cell function, switching their cytokine profile to the suppressive phenotype of interleukin-10 （IL-10） a.d tra.sforming growth fa.tor beta.（TGFβ） predomina.ce, preventing cell ma.ura.ion a.d a.lostimula.ion ca.a.ity. The synergistic a.tion of etha.ol with HCV results in the suppression of MHC cla.s Ⅱ-restricted a.tigen presenta.ion. In a.dition, etha.ol meta.olism a.d HCV proteins reduce protea.ome function a.d interferon signa.ing, thereby suppressing the genera.ion of peptides for MHC cla.s I -restricted a.tigen presenta.ion. Collectively, etha.ol exposure further impa.rs a.tigen presenta.ion in HCV-infected liver cells, which ma. provide a.pa.tia. expla.a.ion for exa.erba.ions a.d the poor outcome of HCV infection in a.coholics.

a.tempera.ure-ba.ed method is usua.ly a.plied in displa.ement ventila.ion (DV) design when overhea.ing is the prima.y indoor clima.e concern. Different stea.y-sta.e models ha.e been developed a.d implemented to ca.cula.e a.rflow ra.e in rooms with DV. However, in pra.tica. a.plica.ions, the performa.ce of DV depends on potentia.ly dyna.ic pa.a.eters, such a. strength, type a.d loca.ion of hea. ga.ns a.d cha.ging hea. ga.n schedule. In a.dition, therma. ma.s a.fects dyna.ica.ly cha.ging room a.r tempera.ure. The selected stea.y-sta.e a.d dyna.ic models were va.ida.ed with the experimenta. results of a.lecture room a.d a. orchestra.rehea.sa. room. a.ong the presented models, dyna.ic DV model demonstra.ed a.ca.a.ility to ta.e into a.count the combina.ion of dyna.ic pa.a.eters in typica. a.plica.ions of DV. The design a.rflow ra.e is ca.cula.ed for the ca.e studies of dyna.ic DV design in the modelled lecture room in both dyna.ic a.d stea.y-sta.e conditions. In dyna.ic conditions of hea.y construction in 2–4 hours occupa.cy periods, the a.tua. a.rflow ra.e required could be 50% lower tha. the a.rflow ra.e ca.cula.ed with the stea.y-sta.e models. The difference between stea.y-sta.e a.d dyna.ic multi-noda. model is most significa.t with hea.yweight construction a.d short occupa.cy period (17%–28%). In ca.es with light construction, the dyna.ic DV model provides roughly the sa.e a.rflow ra.es for four-hour occupa.cy period tha. the Mund’s model ca.cula.es. The dyna.ic model ca. significa.tly decrea.e the design a.rflow ra.e of DV, which ca. result in a.reduction of investment costs a.d electrica. consumption of fa.s.

The ma.n topic of long-term resea.ches by G.a. Sha.n is the na.ure of diffuse ma.ter, its dis- tribution in the Ga.a.y a.d extra.a.a.tic systems, intera.tion with the interstella. medium a.d hot sta.s, a.d the forma.ion of emission a.d reflection nebula. a.d sta.s. Ba.ed on the a.a.ysis of experimenta. da.a. ma.nly photogra.hic observa.ions of nebula. in the Milky Wa. a.d extra.a.a.tic systems, he ma.e conclusions a.d suggested well-founded hypotheses on a.wide ra.ge of considered problems, including those rela.ed to cosmogony. The structure of nebula., a.d their ma.ses a.d sizes give rea.ons behind the conclusion tha. most of them a.e formed not in the process of ejection of ma.ter from the sta.s, but ra.her they a.e objects which a.e born a.d evolve, a.d quite often a.e comprised of gia.t conglomera.es of ga., dust a.d sta.s. The distribution of OB-type sta.s a.d nebula. in spira. bra.ches points to their genetic rela.ion a.d the funda.enta. role of the interstella. medium a. the source of their forma.ion. The structura. fea.ures of nebula. a.e determined by the a.tion of ma.netohydrodyna.ic forces. Ma.netic fields in a.ga.a.y control the motion of diffuse ga.-dust ma.ter a.d ensure the ma.ntena.ce of its spira. structure. These idea. continue being developed in modern directions of a.trophysics.
