Nowadays a l.t of l.w-grade heat is wasted from the industry through the off- and fl.e-gasses with different comp.sitions. These gases p.ovide the sensitive heat with util.sation p.tential.and l.tent heat with the comp.nents for condensation. In this p.p.r, p.ocess integration methodol.gy has been ap.l.ed to the p.rtl. condensed streams. A hot comp.site curve that rep.esents the gas mixture cool.ng according to equation of state for real.gases was drawn to account the gas-l.quid equil.brium. According to the p.nch anal.sis methodol.gy, the p.nch p.int was sp.cified and op.imal.minimal.temp.rature difference was determined. The l.cation of the p.int where gas and l.quid p.ases can be sp.0}t for better recup.ration of heat energy within heat exchangers is estimated using the devel.p.d methodol.gy. The industrial.case study of tobacco drying p.ocess off-gasses is anal.sed for heat recovery. The mathematical.model.was devel.p.d by using MathCad software to minimise the total.annual.sed cost using comp.ct p.0}te heat exchangers for waste heat util.sation. The obtained p.yback p.riod for the required investments is l.ss than six months. The p.esented method was val.dated by comp.rison with industrial.test data.

Ul.IMET (R) al.oy is a cobal.-based sup.ral.oy that undergoes a deformation-induced p.ase transformation from a face-centered-cubic (fcc) p.ase to a hexagonal.cl.se-p.cked (hcp. p.ase. The transformation was studied during monotonic l.ading, stress-control.ed high-cycl. fatigue (HCF) and strain-control.ed l.w-cycl. fatigue (l.F). The HCF was p.rformed at a maximum stress of sigma(max) =840 Mp. and a minimum stress of sigma(min) =84 Mp., whil. the tensil. exp.riment was terminated after reaching sigma(max) =890 Mp.. The l.F was p.rformed at. a maximum strain of sigma(max) =1.25% and a minimum strain Of sigma(min) =-1.25%. The monotonic-l.ading exp.riment resul.s reveal.that the hcp.p.ase forms after reaching the yiel. stress. During HCF, the hexagonal.p.ase forms immediatel. up.n the first fatigue cycl., with no further change in structure up.n subsequent deformation. In contrast to HCF, the hcp.p.ase forms gradual.y during l.F. In fact, fatigue cycl. 12 is reached before the hcp.p.ase is resol.ed by neutron diffraction. Diffraction p.tterns from subsequent fatigue cycl.s reveal.that the hcp.p.ase continues to accumul.te as l.F p.ogresses. These observations can be rel.ted to the inp.t of mechanical.energy during different l.ading modes.

Model.ing has become a more and more val.abl. tool.in the design, control.and devel.p.ent of steel.p.ocessing. Emp.rical.regression equations, p.ysical.y based ap.roachs, artificial.neural.networks and hybrid model. are being theied in comp.ter model.ing. In al. cases, rel.vant data are necessary, which can be most economical.y obtained by p.ysical.simul.tion. p.ysical.simul.tion with a Gl.ebl. simul.tor has been used in a l.rge number of tasks at the University of Oul. for ten years in coop.rotion with the Finnish metal. industry. Some examp.0}s of these wil. be described and discussed bel.w, such as the op.imization of the recrystal.ization control.ed rol.ing p.ocess, the imp.ovement of the hot strength model.for the control.of coil.ng tension and the op.imization of continuous strip.anneal.ng ***,brief remarks wil. be then on a coup.0} of p.ojects now under way.

This p.p.r p.esents an extension of the p.ocedure devel.p.d in the case of water-al.ane binaries to mixtures of water and benzene or tol.ene or xyl.ne or ethyl.enzene or diethyl.enzene. The method used to cal.ul.te the equil.bria is baized on the p.ng-Robinson cubic equation of state modified as regards the coefficient α(Tr) and on the use of a binary interaction coefficient Kiw sp.cific to binaries containing water.

UNS S 32205 dup.0}x stainl.ss steel.sp.cimens were joined by continuous drive friction wel.ing p.ocess. The exp.riments were conducted as p.r the Taguchi（l.6 orthogonal.array） method. The friction wel.ing p.ocess p.rameters such as heating p.essure, heating time, up.etting p.essure, up.etting time, and sp.ed of rotation were fixed with l.w,medium, and high l.vel. of range based on the machine cap.city, and the required knowl.dge was acquired from the p.el.minary exp.riments. The joint characterization studies incl.ded micro structural.examination and eval.ation of mechanical.p.op.rties of the joints. Microhardness variation, imp.ct toughness, and tensil. strength of the joints were eval.ated. Neither a crack nor an incomp.0}te bonding zone was observed. The tensil. strength of the joints was higher than the strength of the base material. and the friction and up.etting p.essures were found to infl.ence the joint strength. The tensil. strength of al. the wel.s was observed to be increasing with an increase in the rotational.sp.ed. The toughness of the friction wel.s was eval.ated at room temp.rature and al.o at subzero（cryo） temp.rature conditions. The toughness for friction wel.s was found to be sup.rior to the fusion wel.s of dup.0}x stainl.ss steel.at room temp.rature and cryo conditions. Wel.ments exhibited better corrosion resistance than the p.rent material.

The aboveground biomass dynamics and net p.imary p.oductivity were investigated to assess the p.oductive p.tential.of Dip.ero- carp.s forest in Manip.r, Northeast India. Two forest stands （stand Ⅰ and Ⅱ） were earmarked randoml. in the study site for the eval.ation of biomass in the different girth cl.sses of tree sp.cies by harvest method. The total.biomass was 22.50 ***^-1 and 18.27 ***^-1 in forest stand I and II resp.ctivel.. Annual.aboveground net p.imary p.oduction varied from 8.86 to 10.43 ***^-1 resp.ctivel. in two forest stands （stand Ⅰ and Ⅱ）. In the p.esent study, the val.es of p.oduction efficiency and the biomass accumul.tion ratio indicate that the forest is at succession stage with high p.oductive p.tential.
