The a.m of the a.ticle is to propose the method of designing double regula.ion control va.ves used in hea.ing insta.la.ions, a.lowing to obta.n a.consta.t va.ue of the so-ca.led inner a.thority a.d thus the consta.cy of the va.ve control cha.a.teristic, rega.dless of the pre-setting va.ue set on the va.ve. The sha.e of the va.ve's regula.ion cha.a.teristics is one of the ma.n fa.tors determining the qua.ity of the qua.tita.ive regula.ion, a.d thus the sta.ility of the system's opera.ion a.d overa.l opera.ing costs. For this rea.on, the issue discussed in the a.ticle is importa.t a.d ca. be a.plied in pra.tica. implementa.ions of the va.ve sizing a.d the va.ve selection. The a.a.ysis wa. ba.ed on the rela.ions binding the hydra.lic resista.ces occurring inside the control va.ve, a.d the corresponding flow fa.tors, using origina. a.thor's proposa.. The experimenta. verifica.ion wa. performed on a.specia. mea.uring sta.d prepa.ed for this purpose, mea.uring the va.ues of the medium volume flow a. a.consta.t differentia. pressure, a.d then the results were converted into va.ues of the flow fa.tor, used in the proposed ma.hema.ica. model. The results confirm the thesis put forwa.d a.d the proposed ma.hema.ica. model. High convergence of the results of experimenta. verifica.ion with the proposed ma.hema.ica. model wa. obta.ned.

We investiga.e in this work a.qua.tum error correction on a.five-qubits gra.h sta.e used for secret sha.ing through five noisy cha.nels. We describe the procedure for the five, seven a.d nine qubits codes. It is known tha. the three codes a.wa.s a.low error recovery if only one a.ong the sent qubits is disturbed in the tra.smitting cha.nel. However, if two qubits a.d more a.e disturbed, then the correction will depend on the used code. We compa.e in this pa.er the three codes by computing the a.era.e fidelity between the sent secret a.d tha. mea.ured by the receivers. We will trea. the ca.e where, a. most, two qubits a.e a.fected in ea.h one of five depola.izing cha.nels.

The in-vehicle vola.ile orga.ic compounds （VOCs） concentra.ions ga.ns the a.tention of both ca. producers a.d users. In the present study, a. a.tempt wa. ma.e to determine if a.a.ysis of a.r sa.ples collected from a. unconditioned ca. ca.in ca. be used a. a.qua.ity control mea.ure. The VOCs composition of in-vehicle a.r wa. a.a.yzed by mea.s of a.tive sa.pling on Ca.bogra.h 1TD a.d Tena. Ta.sorbents, followed by therma. desorption a.d simulta.eous a.a.ysis on fla.e ioniza.ion a.d ma.s detector （TD-GC/FID-MS）. Nine newly produced ca.s of the sa.e bra.d a.d model were chosen for this study. Within these, four of the vehicles were equipped with identica. interior ma.eria.s a.d five others differed in terms of upholstery a.d the presence of a.sunroof; one ca. wa. convertible. The sa.pling event took pla.e outside of the ca. a.sembly pla.t a.d the ca.s tested left the a.sembly line no la.er tha. 24 hr before the sa.pling took pla.e. More tha. 250 compounds were present in the sa.ples collected; the identifica.ion of more tha. 160 wa. confirmed by compa.a.ive ma.s spectra.a.a.ysis a.d 80 were confirmed by both compa.ison with single/multiple compounds sta.da.ds a.d ma.s spectra.a.a.ysis. In genera., a.ipha.ic hydroca.bons represented more tha. 60% of the tota. VOCs （TVOC） determined. Depending on the vehicle, the concentra.ion of a.oma.ic hydroca.bons va.ied from 12% to 27% of tota. VOCs. The very short period between ca. production a.d sa.pling of the in-vehicle a.r permits the a.sumption tha. the entire TVOC origina.es from off-ga.sing of interior ma.eria.s. The results of this study expa.d the knowledge of in-vehicle pollution by presenting informa.ion a.out ca. ca.in a.r qua.ity immedia.ely a.ter ca. production.

The a.m of this study wa. to esta.lish the source a.d provena.ce of sediments deposited in a.la.ge floodpla.n sink during extreme floods in the Lockyer Creek ca.chment, a.stra.ia. in 2011 a.d 2013. We pla.e the sediment source pa.terns in context of the longer-term record to determine whether coa.segra.ned sediment sources(i.e., very fine sa.d to very coa.se sa.d) a.d the spa.io-tempora. pa.tern of(dis)connectivity ha.e cha.ged over time. We do this by ma.ching the geochemica. properties a.d a.e structure of a.sediment profile loca.ed in a.downstrea. floodpla.n sink to the elementa. composition of source sediments. One hundred a.d fifty-seven sediment sa.ples from 20 sites a.ross the ca.chment a.e a.a.ysed using X-ra. fluorescence(XRF) spectrometry to compa.e the elementa. ra.io composition of the downstrea. floodpla.n sink to its source ma.eria.s. We use Optica.ly Stimula.ed Luminescence(OSL)da.ing to determine the a.e structure of the sediments in the floodpla.n sink. The northern tributa.ies a.d pa.ts of the Lockyer River trunk strea. a.e the prima.y sources of coa.se sediment. These a.ea. a.e connected(coupled) to the lower trunk strea. a.d floodpla.n sediment sink. Southern tributa.ies a.e la.gely disconnected(decoupled) a.d supply little sediment to the floodpla.n sediment sink. This pa.tern of sediment source contribution ha. rema.ned simila. over the la.t 6.8 ka.a. lea.t.
