UMnyango Wezempilo Kahulumeni waseKarnataka usanda kuqinisekisa imikhawulo yokusetshenziswa kwe-nitrogen ewuketshezi emikhiqizweni yokudla efana namabhisikidi abhemayo kanye ne-ayisikhilimu, eyethulwe ekuqaleni kukaMeyi. Lesi sinqumo sithathwe ngemuva kokuba intombazane eneminyaka engu-12 ubudala yaseBengaluru ithole imbobo esiswini sayo ngemuva kokudla isinkwa esine-nitrogen ewuketshezi.
Ukusetshenziswa kwe-nitrogen ewuketshezi ekudleni okulungisiwe kuye kwanda eminyakeni yamuva nje, lapho ikhemikhali isetshenziselwa ukufaka umphumela wokubhema ekudleni okuthile, ama-dessert kanye nama-cocktail.
I-nitrogen ewuketshezi emikhiqizweni yokudla kufanele iphathwe ngokucophelela okukhulu. Lokhu kungenxa yokuthi i-nitrogen kumele ipholiswe ekushiseni okukhulu okungu--195.8°C ukuze ibe uketshezi. Uma uqhathanisa, izinga lokushisa esiqandisini sasekhaya lehla liye ku--18°C noma ku--20°C.
Igesi encibilikisiwe efrijini ingabangela ukushaqeka uma ithinta isikhumba nezitho zomzimba. I-nitrogen encibilikisiwe iqandisa izicubu ngokushesha okukhulu, ngakho-ke ingasetshenziswa ezinqubweni zezokwelapha zokubhubhisa nokususa amaqhubu noma izicubu ezinomdlavuza. Lapho i-nitrogen ingena emzimbeni, iphenduka ngokushesha ibe igesi lapho izinga lokushisa likhuphuka. Isilinganiso sokwanda kwe-nitrogen encibilikisiwe kuma-degree Celsius angama-20 siyi-1:694, okusho ukuthi ilitha eli-1 le-nitrogen encibilikisiwe linganda libe amalitha angama-694 e-nitrogen kuma-degree Celsius angama-20. Lokhu kukhula okusheshayo kungaholela ekubhobokeni kwesisu.
"Ngenxa yokuthi ayinambala futhi ayinaphunga, abantu bangase bavezwe kuyo bengazi. Njengoba izindawo zokudlela eziningi zisebenzisa i-nitrogen ewuketshezi, abantu kufanele baqaphele la macala angavamile futhi balandele izincomo. Nakuba kungavamile, kwezinye izimo kungadala umonakalo omkhulu." kusho uDkt. Atul Gogia, umeluleki omkhulu, umnyango wezokwelapha zangaphakathi, iSir Gangaram Hospital.
I-nitrogen ewuketshezi kufanele iphathwe ngokucophelela okukhulu, futhi abaqhubi kufanele basebenzise imishini yokuzivikela ukuvimbela ukulimala ngesikhathi sokulungiselela ukudla. Labo abadla ukudla neziphuzo eziqukethe i-nitrogen ewuketshezi kufanele baqinisekise ukuthi i-nitrogen ishabalale ngokuphelele ngaphambi kokuyidla. "I-nitrogen ewuketshezi ... uma iphathwe kabi noma igwinywe ngephutha, ingabangela umonakalo omkhulu esikhumbeni nasezithweni zangaphakathi ngenxa yokushisa okuphansi kakhulu okungagcinwa yi-nitrogen ewuketshezi. Ngakho-ke, i-nitrogen ewuketshezi kanye neqhwa elomile akufanele kudliwe ngqo noma kuthintane ngqo nesikhumba esiveziwe," kusho i-US Food and Drug Administration esitatimendeni. Uphinde wanxusa abathengisi bokudla ukuthi bangayisebenzisi ngaphambi kokuphakela ukudla.
Igesi kufanele isetshenziswe kuphela ekuphekeni endaweni enomoya omuhle. Lokhu kungenxa yokuthi ukuvuza kwe-nitrogen kungasusa umoya-mpilo emoyeni, okubangela i-hypoxia kanye nokufiphala. Futhi njengoba ingenambala futhi ingenaphunga, ukubona ukuvuza ngeke kube lula.
I-nitrogen iyigesi engasebenzi, okusho ukuthi ayisebenzi nezinto eziningi, futhi isetshenziselwa ukugcina ukudla okupakishiwe kusha. Isibonelo, lapho isikhwama sama-potato chips sigcwele i-nitrogen, sisusa umoya-mpilo esiwuqukethe. Ukudla kuvame ukusabela nomoya-mpilo bese kuba yi-rancing. Lokhu kwandisa isikhathi sokuphila komkhiqizo.
Okwesibili, isetshenziswa ngendlela ewuketshezi ukuqandisa ukudla okusha okufana nenyama, izinkukhu kanye nemikhiqizo yobisi. Ukuqandisa ukudla nge-nitrogen kushibhile kakhulu uma kuqhathaniswa nokuqandisa okuvamile ngoba inani elikhulu lokudla lingaqandiswa ngemizuzu embalwa nje. Ukusebenzisa i-nitrogen kuvimbela ukwakheka kwamakristalu eqhwa, okungalimaza amangqamuzana futhi kuqede amanzi ekudleni.
Ukusetshenziswa okubili kobuchwepheshe kuvunyelwe ngaphansi komthetho wezwe wokuphepha kokudla, ovumela ukusetshenziswa kwe-nitrogen ekudleni okuhlukahlukene, okuhlanganisa imikhiqizo yobisi olubilisiwe, ikhofi netiye elilungele ukuphuzwa, amajusi, kanye nezithelo ezihlutshiwe nezisikiwe. Lo mthethosivivinywa awukhulumi ngokuqondile ngokusetshenziswa kwe-nitrogen ewuketshezi emikhiqizweni eqediwe.
U-Anonna Dutt ungumlobeli wezindaba wezempilo oyinhloko we-The Indian Express. Ukhulume ngezihloko ezahlukahlukene, kusukela ekuthwaleni okwandayo kwezifo ezingathathelwana njengesifo sikashukela kanye nomfutho wegazi ophakeme kuya enseleleni yezifo ezithelelanayo ezivamile. Ukhulume ngempendulo kahulumeni kubhubhane lwe-Covid-19 futhi walandela eduze uhlelo lokugoma. Indaba yakhe yashukumisela uhulumeni wedolobha ukuthi atshale imali ekuhlolweni kwekhwalithi ephezulu kwabampofu futhi avume amaphutha ekubikeni okusemthethweni. UDutt unesithakazelo esikhulu ohlelweni lwesikhala sezwe futhi ubhale ngemisebenzi ebalulekile efana neChandrayaan-2 kanye neChandrayaan-3, i-Aditya L1 kanye neGaganyaan. Ungomunye wabafundi bokuqala abangu-11 be-RBM Malaria Partnership Media Fellows. Uphinde wakhethwa ukuthi ahlanganyele ohlelweni lokubika lwesikhashana lwe-Dart Center eColumbia University. UDutt wathola i-BA yakhe eSymbiosis Institute of Media and Communications, ePune kanye ne-PG evela e-Asian Institute of Journalism, eChennai. Waqala umsebenzi wakhe wokubika eHindustan Times. Uma engasebenzi, uzama ukuthulisa izikhova zaseDuolingo ngamakhono akhe olimi lwesiFulentshi futhi ngezinye izikhathi uya endaweni yokudansa. … funda kabanzi
Inkulumo yakamuva yenhloko ye-RSS uMohan Bhagwat kuma-cadet aseSangh eNagpur ibonwe njengokusola i-BJP, isenzo sokubuyisana kwabaphikisi kanye namazwi okuhlakanipha kulo lonke isigaba sezombusazwe. UBhagwat ugcizelele ukuthi "uSevak wangempela" akufanele abe "ozikhukhumezayo" futhi izwe kufanele liphathwe ngesisekelo "sesivumelwano". Uphinde wabamba umhlangano ovaliwe no-UP CM Yogi Adityanath ukuveza ukwesekwa kweSangh.
