For the.challe.ging nature.of the.zirconium e.vironme.t analysis, this study consists to analyze.the.e.e.troche.ical be.avior of Zirconium in both aque.us and organic me.ia. To that e.d first the.e.e.trolytic me.ia was se.e.te. on the.basis of the.Pourbaix pote.tial-pH diagram, which provide. informations on the.pre.ominance.of Zr(IV) ion and Zr in aque.us me.ia. In aque.us me.ia, analyze. we.e.first carrie. out in acidic me.ia the. in basic me.ia. Studie. have.thus re.e.le. that the.acidic e.vironme.t is not favourable.for the.e.e.troche.ical analysis of zirconium. Voltammograms obtaine. in an acidic e.vironme.t show no zirconium de.e.tion signal;this is due.to the.strong pre.e.ce.of H+ ions in the.solution. We.have.also obse.ve. in acidic me.ia the.phe.ome.on of passivation of the.e.e.trode.surface. In aque.us alkaline.me.ia (pH = 13), we.have.drawn in re.uction se.e.al Inte.sity-Pote.tial curve. by fixingsome.te.hnical parame.e.slike.scanning spe.d, rotation spe.d of the.e.e.trode. The.obtaine. voltammograms show cathodic wave., starting from -1.5 V/DHW and attribute. to the.re.uction of Zr (IV) to Zr (0). The.last phase.of this study focuse. on the.e.e.troche.ical analysis of zirconium in an organic me.ia. In this me.ia, se.e.al inte.sity-pote.tial curve. we.e.plotte. in re.uction and in cyclic voltamme.ry with various parame.e.s. Through se.e.al re.uction analysis, the.Zr (IV) was re.uce. to Zr (0) to the.pote.tial of -1.5 V/DHW. The.e.e.troche.ical analysis of zirconium in organic me.ia se.ms globally e.sie. to achie.e.thanks to its large.solve.t window (i.e. dime.hylformamide.(DMF) solve.t window > 6 V).

The.aim of this study was to provide.a simple. e.sy-to-use.incubation syste. for small-scale.rural poultry farme.s far from the.e.e.tricity grid. To this e.d, a naturally ve.tilate. solar the.mal incubator was built and e.pe.ime.tally te.te..

Wate. was use. as the.he.t transfe. fluid, and an e.CM was inte.rate. into the.incubation chambe. for ope.ation at night or whe. the.sun was hidde.. The.he.t ge.e.ate. by the.solar colle.tor and store. in the.he.t transfe. fluid is transporte. to the.incubation chambe. by the.mosiphon to he.t the.chambe.. Te.pe.ature.and humidity probe. powe.e. by a solar pane. we.e.place. at various locations to monitor the.the.mo-hygrome.ric e.ficie.cy of the.incubation syste.. The.incubator, he.te. by natural conve.tion, prove. to function normally, and the.incubation chambe. was maintaine. throughout the.incubation pe.iod within a te.pe.ature.range.of 35.53˚C to 39.53˚C and re.ative.humidity ave.aging 49.4% to 68.5%. The.e.pe.ime.t was carrie. out by introducing 30 e.gs and the.re.ults of the.e.pe.ime.tal study showe. that the.incubator’s e.ficie.cy was 87%. The.pe.formance.te.ts gave.a fe.tility rate.of 93% and a hatching rate.of 93%, i.e. 28 fe.tile.e.gs and 26 hatche. e.gs, re.pe.tive.y.
