Dhipatimendi reHutano reKarnataka State munguva pfupi yapfuura rakasimbisa zvirambidzo pakushandiswa kwenitrogen yemvura muzvigadzirwa zvekudya zvakaita semabhisikiti anosvuta neayisikirimu, zvakatangwa kutanga kwaChivabvu. Sarudzo iyi yakaitwa mushure mekunge musikana ane makore gumi nemaviri ekuberekwa wekuBengaluru abuda buri mudumbu make mushure mekunge adya chingwa chine nitrogen yemvura.
Kushandiswa kwenitrogen yemvura muzvikafu zvakagadzirwa kwakawedzera mumakore achangopfuura, nemakemikari anoshandiswa kupa simba reutsi kune zvimwe zvekudya, madhizeti nemacocktails.
Nitrogen yemvura muzvigadzirwa zvekudya inofanira kubatwa nokungwarira kukuru. Izvi zvinodaro nekuti nitrogen inofanira kutonhodzwa kusvika patembiricha yakanyanya ye -195.8°C kuti iite fluid. Kana tichienzanisa, tembiricha iri mufiriji yemumba inodzikira kusvika pa -18°C kana -20°C.
Gasi rakanyungudika mufiriji rinogona kukonzera chando kana rikasangana neganda nenhengo dzemuviri. Nitrogen yemvura inoomesa nyama nekukurumidza, saka inogona kushandiswa mukurapa kuparadza nekubvisa mapundu kana kenza. Kana nitrogen ikapinda mumuviri, inokurumidza kuchinja kuita gasi kana tembiricha yakwira. Chiyero chekuwedzera kwenitrogen yemvura pa20 degrees Celsius i1:694, zvinoreva kuti 1 litre yenitrogen yemvura inogona kuwedzera kusvika 694 litres yenitrogen pa20 degrees Celsius. Kuwedzera uku nekukurumidza kunogona kutungamira mukuboorwa kwedumbu.
"Nekuti haina ruvara uye haina hwema, vanhu vanogona kuiwana vasingazive. Sezvo maresitorendi akawanda achishandisa nitrogen yemvura, vanhu vanofanira kuziva nezvezviitiko izvi zvisingawanzoitiki uye kutevedzera mazano. Kunyangwe zvisingawanzoitiki, mune dzimwe nguva zvinogona kukonzera kukuvara kukuru." "Akadaro Dr Atul Gogia, mukuru wezvekurapa, dhipatimendi rezvekurapa mukati, Sir Gangaram Hospital.
Nitrogen yemvura inofanira kubatwa nokungwarira kukuru, uye vanoshanda vanofanira kushandisa michina yekudzivirira kudzivirira kukuvara panguva yekugadzirira chikafu. Avo vanodya chikafu nezvinwiwa zvine nitrogen yemvura vanofanira kuva nechokwadi chekuti nitrogen yanyangarika zvachose vasati vadya. "Nitrogen yemvura ... kana ikasabatwa zvakanaka kana kudyiwa netsaona, inogona kukonzera kukuvara kwakanyanya paganda nenhengo dzemukati nekuda kwekupisa kwakaderera kunogona kuchengetwa nenitrogen yemvura. Naizvozvo, nitrogen yemvura nechando chakaoma hazvifanirwe kudyiwa zvakananga kana kusangana zvakananga neganda rakavhurika.", US Food and Drug Administration yakadaro mumashoko. Akakurudzirawo vatengesi vezvekudya kuti vasashandise vasati vapa chikafu.
Gasi rinofanira kushandiswa chete pakubika munzvimbo ine mhepo inofefetera zvakanaka. Izvi zvinodaro nekuti kudonha kwenitrogen kunogona kubvisa okisijeni mumhepo, zvichikonzera kushaya okisijeni uye kushaya mweya. Uye sezvo isina ruvara uye isina hwema, kuona kudonha kwemvura hakuzove nyore.
Nitrogen imhepo isina simba, zvichireva kuti haisangani nezvinhu zvakawanda, uye inoshandiswa kuchengetedza hutsva hwechikafu chakarongedzwa. Semuenzaniso, kana bhegi remachipisi embatatisi rikazadzwa nenitrogen, rinobvisa okisijeni iri mariri. Chikafu chinowanzosangana neokisijeni uye chinova nehasha. Izvi zvinowedzera hupenyu hwechigadzirwa.
Chechipiri, inoshandiswa mumvura kuti ikurumidze kuomesa chikafu chitsva chakadai senyama, huku nezvigadzirwa zvemukaka. Kuomesa chikafu nenitrogen kunodhura zvishoma kana tichienzanisa neomesa chikafu chekare nekuti chikafu chakawanda chinogona kuomeswa mumaminitsi mashoma chete. Kushandisa nitrogen kunodzivirira kuumbwa kwemakristaro echando, izvo zvinogona kukuvadza masero uye kuderedza mvura muchikafu.
Mashandisirwo maviri aya ehunyanzvi anotenderwa pasi pemutemo wenyika wekuchengetedza chikafu, uyo unobvumidza kushandiswa kwenitrogen muzvikafu zvakasiyana-siyana, zvinosanganisira zvigadzirwa zvemukaka wakaviriswa, kofi netii zvakagadzirira kunwiwa, majusi, uye michero yakabviswa ganda neyakachekwa. Bhiri iri haritauri zvakananga kushandiswa kwenitrogen yemvura muzvigadzirwa zvakapedzwa.
Anonna Dutt ndiye mukuru wezveutano weThe Indian Express. Akataura pamusoro penyaya dzakasiyana-siyana, kubva pakuwedzera kwezvirwere zvisingatapuriranwe zvakaita sechirwere cheshuga neBP kusvika kumatambudziko ezvirwere zvinotapukira.
