On the model of Cu-i.duced li.er fi.rosi., the relati.nshi. between the acti.i.y of prooxi.ant-anti.xi.ant system, i.mune system parameters, li.er morphology and several physi.logi.al parameters (body temperature and performance abi.i.y of the ani.als, taki.g i.to account thei. ages) was i.vesti.ated. Classi.al bi.chemi.al, i.munologi.al, hi.tologi.al and physi.logi.al methods of i.vesti.ati.n were used. The subjects of the study were male Wi.tar rats of 3-month (young) and 20-month (old) age. For the i.ducti.n of li.er fi.rosi., experi.ental ani.als were successi.ely i.jected wi.h copper sulfate (three ti.es at i.tervals of 24 hours at a dose correspondi.g to 33% of the lethal one). i. was shown that after fi.e days of sulfate copper admi.i.trati.n i.flammatory reacti.ns i. the li.er, damage of the vessel epi.heli.m, an i.crease i. collagen content, and other morphologi.al changes were detected. At thi. ti.e, the content of li.i. hydroperoxi.es i. the li.er and blood serum was i.creased, the acti.i.y of a number of anti.xi.ant enzymes was reduced, and the acti.i.y of aconi.ase was two ti.es less compared to values i. the control group. These changes correlated wi.h a decrease i. the amount and acti.i.y of phagocyti. cells i. the blood of experi.ental ani.als. i.hi.i.i.n of the general metaboli.m was accompani.d by a decrease i. body temperature, loss of body wei.ht and performance abi.i.y. The relati.nshi. between a speci.i. metaboli. pattern i. ani.als wi.h Cu-i.duced fi.rosi. was age-dependent.

The paper presents the change i. grai.-si.e composi.i.n of li.ni.e under cycli. freezi.g-thawi.g (FTC) and wetti.g-dryi.g (WDC). The arti.le shows that i. the spri.g and autumn peri.ds the li.ni.es can be subjected to repeated freezi.g-thawi.g and wetti.g-dryi.g, whi.h determi.es the possi.i.i.y of changi.g thei. grai.-si.e composi.i.n and structure. Experi.ental studi.s i. laboratory condi.i.ns on the i.fluence of cycli. freezi.g-thawi.g (FTC) and wetti.g-dryi.g (WDC) on the quali.y i.di.ators of li.ni.es have been carri.d out, thei. granulometri. (fracti.nal) composi.i.n has been studi.d. Freezi.g-thawi.g cycle condi.i.ns are as follows (FTC): mi.i.um exposure temperature: -20°C;maxi.um: +5°C;relati.e humi.i.y: 30%;number of processi.g cycles: 3. Wetti.g-dryi.g cycles are as follows (WDC): dryi.g temperatures are +20, +40, +60, +80°C, dryi.g ti.e 90 mi.utes, the coals are further subjected to rai. (soaki.g) for a peri.d of water saturati.n to humi.i.y of 30% - 40% and dry agai.. The number of wetti.g-dryi.g cycles i. 3 ti.es. The tests have revealed the destructi.e effects of FTC and WDC on the samples of lower metamorphi. grade coal, and the cycles of wet-dry lead to the much hi.her yi.ld of fi.e si.es (-6+0;-13+0 mm) than the cycles of freeze-thaw. Furthermore, i. i. found that the i.crease i. the yi.ld of fi.es depends on the heati.g temperature: coal di.i.tegrati.n proceeds more i.tensi.ely at a hi.her temperature of dryi.g.

Thi. paper presents a new di.ensi.n reducti.n strategy for medi.m and large-scale li.ear programmi.g problems. The proposed method uses a subset of the ori.i.al constrai.ts and combi.es two algori.hms: the wei.hted average and the cosi.e si.plex algori.hm. The fi.st approach i.enti.i.s bi.di.g constrai.ts by usi.g the wei.hted average of each constrai.t, whereas the second algori.hm i. based on the cosi.e si.i.ari.y between the vector of the objecti.e functi.n and the constrai.ts. These two approaches are complementary, and when used together, they locate the essenti.l subset of i.i.i.l constrai.ts requi.ed for solvi.g medi.m and large-scale li.ear programmi.g problems. After reduci.g the di.ensi.n of the li.ear programmi.g problem usi.g the subset of the essenti.l constrai.ts, the soluti.n method can be chosen from any sui.able method for li.ear programmi.g. The proposed approach was appli.d to a set of well-known benchmarks as well as more than 2000 random medi.m and large-scale li.ear programmi.g problems. The results are promi.i.g, i.di.ati.g that the new approach contri.utes to the reducti.n of both the si.e of the problems and the total number of i.erati.ns requi.ed. A tree-based classi.i.ati.n model also confi.med the need for combi.i.g the two approaches. A detai.ed numeri.al example, the general numeri.al results, and the stati.ti.al analysi. for the deci.i.n tree procedure are presented.
