Kuundana kwa ayezi pazingwe za magetsi kukhoza kuwononga kwambiri, kusiya anthu opanda kutentha ndi mphamvu kwa milungu ingapo.M'mabwalo a ndege, ndege zimatha kukumana ndi kuchedwa kosatha pamene zikudikirira kuti zisungunuke ndi mankhwala oopsa.
Tsopano, komabe, ofufuza aku Canada apeza njira yothetsera vuto la icing yozizira kuchokera ku gwero losayembekezereka: ma penguin a Gentoo.
Mu kafukufuku yemwe adasindikizidwa sabata ino, asayansi aku McGill University ku Montreal adavumbulutsa wayamaunakapangidwe kamene kamatha kuzungulira zingwe zamagetsi, mbali ya boti kapena ngakhale ndege ndikusunga ayezi popanda kugwiritsa ntchito mankhwala.
Asayansi alimbikitsidwa ndi mapiko a ma penguin amtundu wa gentoo, omwe amasambira m'madzi oundana pafupi ndi Antarctica ndipo amatha kukhala opanda madzi oundana ngakhale kunja kukuzizira kwambiri.
"Zinyama zili ndi ... zimakonda kwambiri chilengedwe," Ann Kitzig, wofufuza wamkulu pa kafukufukuyu, adatero poyankhulana."Itha kukhala chinthu choti muwone ndikutengeranso."
Pamene kusintha kwa nyengo kumapangitsa kuti mkuntho wachisanu ukhale wolimba kwambiri, mphepo yamkuntho ya ayezi ikuwononga.Ku Texas chaka chatha, matalala ndi ayezi zidasokoneza moyo watsiku ndi tsiku ndikuchotsa gridi yamagetsi, ndikusiya mamiliyoni opanda kutentha, chakudya ndi madzi kwa masiku ndipo mazana a anthu adamwalira.
Asayansi, akuluakulu a mzindawo ndi atsogoleri a mafakitale akhala akulimbana kwa nthawi yaitali kuti mvula yamkuntho isasokoneze ntchito zachisanu.Amapanga zingwe zamagetsi, makina opangira mphepo ndi mapiko a ndege okhala ndi filimu ya de-icing kapena amadalira zosungunulira za mankhwala kuti achotse madzi oundana mwachangu.
Koma akatswiri a de-icing amati kukonzanso uku kumasiya zambiri zofunika.Nthawi ya alumali yazinthu zolongedza ndi yaifupi.Kugwiritsa ntchito mankhwala kumawononga nthawi komanso kuwononga chilengedwe.
Kitzig, amene kafukufuku wake akugogomezera kugwiritsa ntchito chilengedwe kuthetsa mavuto ovuta a anthu, wakhala zaka zambiri akuyesera kupeza njira yabwino yothanirana ndi ayezi.Poyamba, ankaganiza kuti tsamba la lotus likhoza kukhala loyenera chifukwa limakhetsa madzi ndi kudziyeretsa lokha.Koma asayansi adazindikira kuti sizingagwire ntchito pakagwa mvula yambiri, adatero.
Pambuyo pake, Kitzig ndi gulu lake anapita kumalo osungirako nyama ku Montreal, kumene ma penguin a gentoo amakhala.Anachita chidwi ndi nthenga za penguin ndipo anagwirira ntchito limodzi popanga.
Iwo anapeza kuti nthenga mwachibadwa zimasunga madzi oundana.Malinga ndi Michael Wood, wofufuza yemwe adagwira nawo ntchitoyi ndi Kitzig, nthengazo zimakonzedwa motsatira dongosolo lomwe limawalola kukhetsa madzi mwachilengedwe, ndipo mawonekedwe awo achilengedwe amachepetsa kukhazikika kwa ayezi.
Ofufuzawo adatengera kapangidwe kameneka pogwiritsa ntchito ukadaulo wa laser kuti apange waya wolukamauna.Kenako anayesa kumatira kwa maunawo ku ayezi mumphangayo yamphepo ndipo anapeza kuti kunali kothandiza kwambiri polimbana ndi ayezi kuposa pamwamba pa chitsulo chosapanga dzimbiri.Mankhwala osungunulira mankhwala nawonso safunikira, anawonjezera.
Mauna amathanso kumangirizidwa ku mapiko a ndege, atero a Kitzig, koma zoletsa zoletsa zachitetezo cham'mlengalenga zipangitsa kuti kusintha kotereku kukhale kovuta kukhazikitsa pakanthawi kochepa.
Kevin Golovin, pulofesa wothandizira paukadaulo wamakina ku yunivesite ya Toronto, adati chochititsa chidwi kwambiri panjira yochotsera icingyi ndikuti ndi waya wa waya, womwe umapangitsa kuti ukhale wokhazikika.
Njira zina, monga mphira wosamva madzi oundana kapena malo opangidwa ndi masamba a lotus, sizokhazikika.
"Amagwira ntchito bwino mu labu," atero a Golovin, omwe sanachite nawo kafukufukuyu, "ndipo amawulutsa bwino panja."
Waya wachitsulo chosapanga dzimbirimaunandi mtundu wa mawaya oluka opangidwa kuchokera kumtunda wapamwamba wosapanga dzimbirizitsulowaya.Amadziwika ndi kukhazikika kwake, mphamvu zake komanso kukana dzimbiri.Waya wamtunduwu amagwiritsidwa ntchito m'njira zosiyanasiyana kuphatikiza kusefera, kulekanitsa, chitetezo, ndi kulimbikitsa m'mafakitale osiyanasiyana monga chakudya ndi zakumwa, kukonza mankhwala, migodi, ndi zomangamanga.Imapezeka m'makalasi ndi makulidwe osiyanasiyana kuti ikwaniritse zofunikira zenizeni.Njira zoluka zomwe zimagwiritsidwa ntchito muzitsulo zosapanga dzimbiri zamawaya zimakhalanso zosiyanasiyana ndipo zimatha kukhala zoluka mpaka zovuta.Zodziwika kwambiri ndi monga plain weave, twill weave, Dutch weave, ndi twilled dutch weave.
