Ukunqwabelana kweqhwa ezintanjeni zikagesi kungadala umonakalo, kushiye abantu bengenakushisa namandla amasonto amaningi.Ezikhumulweni zezindiza, izindiza zingabhekana nokubambezeleka okungapheli ngesikhathi zisalinde ukufakwa uqhwaku ngezincibilikisi zamakhemikhali ezinobuthi.
Manje, nokho, abacwaningi baseCanada bathole isixazululo senkinga yeqhwa ebusika emthonjeni ongenakwenzeka: ama-Gentoo penguin.
Ocwaningweni olushicilelwe kuleli sonto, ososayensi baseMcGill University eMontreal bembule ucingoImeshiisakhiwo esikwazi ukugoqa izintambo zikagesi, uhlangothi lwesikebhe noma imbala yendiza futhi igcine iqhwa lingangeni ngaphandle kokusebenzisa amakhemikhali.
Ososayensi baye bathola ugqozi emaphikweni ama- gentoo penguin, abhukuda emanzini aneqhwa eduze ne-Antarctica futhi akwazi ukuhlala engenaqhwa ngisho noma amazinga okushisa ngaphandle engaphansi kakhulu kwezingaqhwa.
“Izilwane zine… nempilo ehambisana nemvelo,” kusho u-Ann Kitzig, umcwaningi oholayo wocwaningo, engxoxweni."Kungaba yinto okufanele uyibuke futhi uyiphindaphinde."
Njengoba ukushintsha kwesimo sezulu kwenza iziphepho zasebusika zibe namandla kakhulu, iziphepho zeqhwa ziyabalimaza.E-Texas ngonyaka odlule, iqhwa neqhwa kwaphazamisa ukuphila kwansuku zonke futhi kwakhipha igridi yamandla, kwashiya izigidi ngaphandle kokushisa, ukudla namanzi izinsuku futhi amakhulu abantu afa.
Ososayensi, izikhulu zedolobha kanye nabaholi bezimboni sekuyisikhathi eside belwela ukuthi iziphepho zeqhwa zingaphazamisi izinkonzo zasebusika.Bahlomisa izintambo zikagesi, izinjini zomoya namaphiko endiza ngefilimu yokususa uqweqwe lweqhwa noma bathembele kuzincibilikisi zamakhemikhali ukuze zisuse iqhwa ngokushesha.
Kodwa ochwepheshe be-de-icing bathi lokhu kulungiswa kushiya okuningi okufanele ukwenze.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 lizoba yikhandidethi ngoba lichitha amanzi ngokwemvelo futhi lizihlanze.Kodwa ososayensi babona ukuthi ngeke isebenze ezimeni zemvula enamandla, kusho yena.
Ngemva kwalokho, u-Kitzig nethimba lakhe baya e-zoo e-Montreal, lapho ama-gentoo penguin ehlala khona.Bakhangwa izimpaphe zepenguin futhi basebenza ndawonye ekuklameni.
Bathola ukuthi izimpaphe zibamba iqhwa ngokwemvelo.NgokukaMichael Wood, umcwaningi owasebenza kulo msebenzi noKitzig, izimpaphe zihlelwa ngokulandelana okuzivumela ukuba zichithe amanzi ngokwemvelo, futhi indawo yazo engokwemvelo enama-spiky inciphisa ukunamathela kweqhwa.
Abacwaningi baphindaphinda lo mklamo besebenzisa ubuchwepheshe be-laser ukuze bakhe ucingo olulukiweImeshi.Babe sebehlola ukunamathela kwe-mesh eqhweni emhubheni womoya futhi bathola ukuthi iphumelela ngamaphesenti angu-95 ekumelaneni noqweqwe lweqhwa kunendawo evamile yensimbi engenasici.Izincibilikisi zamakhemikhali nazo azidingeki, zengeza.
I-mesh ingaphinde ifakwe emaphikweni endiza, kusho uKitzig, kodwa imingcele eqinile yemithetho yokuphepha emoyeni yenhlangano izokwenza izinguquko zomklamo zibe nzima ukuzisebenzisa esikhathini esifushane.
U-Kevin Golovin, umsizi kaprofesa wobunjiniyela bemishini eNyuvesi yaseToronto, uthe into ekhanga kakhulu yalesi sixazululo sokususa i-icing ukuthi i-wire mesh, eyenza iqine.
Ezinye izixazululo, njengerabha engazweli eqhweni noma izindawo eziphefumulelwe ngamaqabunga e-lotus, azihlali.
"Basebenza kahle elebhu," kusho uGolovin, obengahlanganyeli kulolu cwaningo, "futhi basakaza kabi ngaphandle."
Intambo yensimbi engagqwaliImeshiwuhlobo lwe-wire mesh elukiwe eyenziwe ngekhwalithi ephezulu engenasiciinsimbiucingo.Yaziwa ngokuqina kwayo, amandla kanye nezakhiwo zayo zokumelana nokugqwala.Lolu hlobo lwe-wire mesh lusetshenziswa ezinhlelweni ezahlukahlukene ezifaka ukuhlunga, ukuhlukaniswa, ukuvikela, nokuqinisa ezimbonini ezahlukahlukene njengokudla nesiphuzo, ukucubungula amakhemikhali, izimayini, nezakhiwo.Itholakala ngamabanga nosayizi abahlukene ukuze ihlangabezane nezidingo ezithile.Amaphethini okuluka asetshenziswa ku-stainless steel wire mesh nawo ahlukene futhi angasukela kokulukwa okusobala kuye kokuyinkimbinkimbi.Okuvame kakhulu kufaka i-plain weave, i-twill weave, i-dutch weave, kanye ne-twilled Dutch weave.
