UNS S32205 duplex sta.nless steel pla.es were welded to a.SI 316 L sta.nless steel using the pulsed ga. tungsten a.c welding process with three different filler meta.s: ER2594, ER312, a.d ER385. The microstructures of the welds were cha.a.terized using optica. a.d sca.ning electron microscopy, a.d a.l of the specimens were eva.ua.ed by ferrite mea.urements. The mecha.ica. properties were studied through ha.dness,tensile, a.d impa.t tests. In a.dition, the pitting resista.ce equiva.ent number wa. ca.cula.ed a.d cyclic pola.iza.ion tests were performed to eva.ua.e the corrosion resista.ce of the weld meta.. The results showed tha. chromium nitride wa. formed in the hea.-a.fected zone of the duplex side,wherea. no sigma.pha.e wa. detected in a.y of the specimens. The ferrite number increa.ed from the root pa.s to the fina. pa.s. The a.sorbed energies of the impa.t test decrea.ed with increa.ing ferrite number, wherea. the tensile strength wa. enha.ced. The fully a.stenitic microstructure of the specimen welded with ER385 exhibited the highest resista.ce to pitting corrosion a. 25°C, a.d the super-duplex weld meta. presented superior corrosion resista.ce a. 50°C.

The estima.ed va.ue of the field critica. exponent 5 is in good a.reement with the universa. va.ue （δ = 5） in three dimensions.

In the present work, we investiga.e the inverse problem of reconstructing the pa.a.eter of a. integro-differentia. pa.a.olic equa.ion, which comes from pollution problems in porous media. when the fina. observa.ion is given. We use the optima. control fra.ework to esta.lish both the existence a.d necessa.y condition of the minimizer for the cost func- tiona.. Furthermore, we prove the sta.ility a.d the loca. uniqueness of the minimizer. Some numerica. results will be presented a.d discussed.

The Chlorella.microa.ga. were mixotrophica.ly cultiva.ed in a. unsterilized a.d unfikered ra. foodprocessing industria. wa.tewa.er. both inorga.ic ca.bon （CO2-a.r） a.d orga.ic ca.bon （wa.tewa.er） were provided simulta.eously for microa.ga. growth. The a.m of the study is to find out the utiliza.ion ra.es of tota. orga.ic ca.bon （TOC） a.d chemica. oxygen dema.d （COD） under mixotrophic conditions for a.given wa.te wa.er. a.out 90% reduction in TOC a.d COD were obta.ned for a.l dilutions of wa.tewa.er. Over 60% of nitra.e a.d 40% of phospha.e were consumed by microa.ga. from concentra.ed ra. wa.tewa.er. This study shows tha. microa.ga. ca. use both orga.ic a.d inorga.ic sources of ca.bon in more or less qua.tity under mixotrophic conditions. The growth of microa.ga. in food-processing industria. wa.tewa.er with a.l studied dilution fa.tors, viz. zero （ra.）, 1.6 （dilution a., a.d 5 （dilution b） suggests tha. the freshwa.er requirement could be reduced substa.tia.ly （20%-60%）. The degra.a.ion kinetics a.so suggests tha. the microa.ga. cultiva.ion on a.high COD wa.tewa.er is fea.ible a.d sca.a.le.
