Ukuqhwaza ezintanjeni zikagesi kungadala umonakalo, kushiye abantu bengenakushisa nogesi amasonto amaningi.Ezikhumulweni zezindiza, izindiza zingabhekana nokulibaziseka okungapheli zilinde ukulashwa eqhweni ngezincibilikisi zamakhemikhali anobuthi.
Nokho, manje, abacwaningi baseCanada bathole ikhambi leqhwa lasebusika emthonjeni ongenakwenzeka: ama-gentoo penguin.
Ocwaningweni olushicilelwe kuleli sonto, ososayensi baseMcGill University eMontreal bembule aucingoisakhiwo semeshi esingasonga izintambo zikagesi, izinhlangothi zezikebhe ngisho nezindiza futhi kuvimbele ukusetshenziswa kwamakhemikhali ngaphandle kokusebenzisa amakhemikhali.phezulu.
Ososayensi baye bathola ugqozi emaphikweni ama- gentoo penguin, abhukuda emanzini aneqhwa eduze ne-Antarctica futhi ahlale engenaqhwa ngisho nalapho amazinga okushisa engaphansi kwezingaqhwa.
"Izilwane zine... indlela ebukhali kakhulu yokuxhumana nemvelo," kusho u-Ann Kitzig, umcwaningi oholayo ocwaningweni, engxoxweni."Kungaba yinto okufanele uyibuke futhi uyiphindaphinde."
Iziphepho zeqhwa zidala umonakalo omkhulu njengoba ukushintsha kwesimo sezulu kwenza iziphepho zasebusika zibe namandla kakhulu.E-Texas ngonyaka odlule, iqhwa neqhwa kwaphazamisa ukuphila kwansuku zonke futhi kwavala igridi yamandla, kwashiya izigidi ngaphandle kokushisa, ukudla namanzi izinsuku eziningi futhi zabulala amakhulu.
Ososayensi, izikhulu zedolobha kanye nabaholi bezimboni kudala bezabalaza ukuze bavimbele izivunguvungu zeqhwa ukuthi zingaphazamisi ukusebenza kwasebusika.Bahlinzeka ngezintambo zikagesi, izinjini zomoya kanye namaphiko endiza anama-de-icer noma bathembele kumakhemikhali amakhemikhali ukuze bazisuse ngokushesha.
Kodwa ongoti bokulwa noqweqwe lukashukela bathi ukulungiswa kushiya okuningi okungafunwa.Isikhathi seshelufu sezinto zokupakisha sifushane.Ukusetshenziswa kwamakhemikhali kudla isikhathi futhi kuyingozi emvelweni.
UKitzig, ucwaningo lwakhe olugxile ekusebenziseni imvelo ukuze kuxazululwe izinkinga eziyinkimbinkimbi zomuntu, usechithe iminyaka ezama ukuthola indlela engcono kakhulu yokubhekana neqhwa.Ekuqaleni, wayecabanga ukuthi iqabunga le-lotus lingase libe yikhandidethi ngoba ligeleza ngokwemvelo futhi lihlanze.Kodwa ososayensi babona ukuthi ngeke isebenze ezimeni zemvula enamandla, kusho yena.
Ngemuva kwalokho, uKitzig nethimba lakhe baya eMontreal Zoo, ikhaya lama-gentoo penguin.Bakhangwa izimpaphe zepenguin futhi bahlangana ukuze bajule kulo mklamo.
Bathola ukuthi izimpaphe zibamba iqhwa ngokwemvelo.UMichael Wood, umcwaningi wephrojekthi noKitzig, uthe izimpaphe zihlelwe ngokulandelana okuzivumela ukuthi zigeleze ngokwemvelo, futhi indawo yazo yemvelo enezipikili inciphisa ukunamathela kweqhwa.
Abacwaningi baphindaphinda umklamo besebenzisa ubuchwepheshe be-laser ukuze benze i-elukiweyoucingoImeshi.Babe sebehlola ukunamathela kwe-mesh eqhweni emhubheni womoya futhi bathola ukuthi yayikwazi ukumelana noqweqwe ngamaphesenti angu-95 kunendawo evamile yensimbi engenasici.Bengeza ngokuthi azikho izincibilikisi zamakhemikhali ezidingekayo nazo.
IImeshiingase futhi ifakwe emaphikweni endiza, kusho uKitzig, kodwa izidingo zemithetho yokuphepha emoyeni yenhlangano zizokwenza izinguquko zomklamo zibe nzima ukuzisebenzisa esikhathini esifushane.
U-Kevin Golovin, uprofesa osizayo wobunjiniyela bemishini eNyuvesi yaseToronto, uthe ingxenye ethakazelisa kakhulu yalesi sixazululo sokulwa noqweqwe lwe-icing ukuthi i-wire mesh eyenza iqine.
Ezinye izixazululo, njengerabha evimbela uqweqwe lwe-icing noma izindawo eziphefumulelwe ngamaqabunga e-lotus, azikwazi ukuqina.
"Basebenza kahle kakhulu elebhu," kusho uGolovin, owayengahlanganyeli kulolu cwaningo.“Abahumushi kahle lapho.”
