UMnyango wezeMpilo eKarnataka State usanda kuqinisekisa imikhawulo ekusetshenzisweni kwe-nitrogen ewuketshezi emikhiqizweni yokudla efana namabhisikidi abhemayo no-Ice Cream, owethulwa ekuqaleni kukaMeyi. Lesi sinqumo sathathwa ngemuva kokuba intombazane eneminyaka engu-12 ubudala evela eBengaluru yathuthukisa umgodi esiswini sayo ngemuva kokudla isinkwa esine-nitrogen ewuketshezi.
Ukusetshenziswa kwe-nitrogen ewuketshezi ekudleni okulungiselelwe kukhuphuke eminyakeni yamuva nje, namakhemikhali asetshenziselwa ukudlulisa umphumela obhemayo kokunye ukudla, ama-dessert kanye nama-cocktails.
I-nitrogen ewuketshezi emikhiqizweni yokudla kufanele iphathwe ngokunakekelwa okwedlulele. Lokhu kungenxa yokuthi i-nitrogen kumele iphonswe ekushiseni okwedlulele kwe--195.8 ° C kuya kuLiquefy. Ukuqhathanisa, izinga lokushisa esiqandisini sasekhaya sehlela cishe -18 ° C noma-20 ° C.
Igesi efrijiwe efrijini ingadala i-frostbite uma ihlangana nesikhumba nezitho. I-liquid nitrogen iqhuma izicubu ngokushesha okukhulu, ngakho-ke ingasetshenziswa ezinhlelweni zezokwelapha zokubhubhisa nokususa ama-warts noma izicubu zomdlavuza. Lapho i-nitrogen ingena emzimbeni, isheshe iphenduke igesi lapho izinga lokushisa likhuphuka. Isilinganiso sokunwetshwa kwe-nitrogen ewuketshezi ku-20 degrees Celsius ngu-1: 694, okusho ukuthi i-1 litre ye-nitrogen ye-liquid ingakhulisa ku-694 amalitha we-nitrogen kuma-20 degrees Celsius. Lokhu kunwetshwa okusheshayo kungaholela ekuqothulweni kwesisu.
"Ngoba angenabala futhi anephunga, abantu bangahle bavezwe kuwo ngokungazi. Njengoba izindawo zokudlela eziningi zisebenzisa i-nitrogen ewuketshezi, abantu kufanele bazi ngalezi zimo ezingavamile futhi balandele izincomo. Yize kungajwayelekile, kwezinye izikhathi kungadala ukulimala okungathi sína. " "Kuthiwa uDkt Atul Gogia, umeluleki ophezulu, uMnyango Wezemithi Yangaphakathi, isibhedlela saseSir Gang Gangaram.
I-nitrogen ewuketshezi kufanele iphathwe ngokunakekelwa okwedlulele, futhi abahlinzeki kufanele basebenzise imishini yokuvikela ukuvikela ukulimala ngesikhathi sokulungiswa kokudla. Labo abadla ukudla neziphuzo eziqukethe i-nitrogen ewuketshezi kufanele baqinisekise ukuthi i-nitrogen ihlakaze ngokuphelele ngaphambi kokuthola. "I-nitrogen ewuketshezi ... Uma i-mishanden noma ifakwe ngengozi, ingadala ukulimala okukhulu esikhunjeni nasezithobeni zangaphakathi ngenxa yamazinga okushisa aphansi kakhulu asetshenziswa yi-nitrogen ewuketshezi. Ngakho-ke, i-nitrogen ewuketshezi neqhwa elomile akufanele kudliwe ngokuqondile noma litholwe ngokuqondile ngesikhumba esiveziwe. ",, Kusho abakwa-US Food and Drug Administration esitatimendeni. Ubuye wanxusa abathengisi bokudla ukuthi bangasebenzisi ngaphambi kokusebenzela ukudla.
Igesi kufanele isetshenziselwe ukupheka endaweni enomoya omuhle. Lokhu kungenxa yokuthi ukuvuza kwe-nitrogen kungasusa umoya-mpilo emoyeni, kubangele i-hypoxia kanye ne-asphyxiation. Futhi njengoba kungenamibala futhi kungenamoya, ukutholwa okuvuzayo ngeke kube lula.
I-nitrogen ingugesi we-inert, okusho ukuthi ayisebenzi ngezinto eziningi, futhi isetshenziselwa ukugcina ubusha bokudla okuhlanganisiwe. Isibonelo, lapho isikhwama samazambane amazambane sigcwele i-nitrogen, kuchithwa umoya-mpilo oqukethe. Ukudla kuvame ukubhekana nomoya-mpilo futhi kuba yi-rancid. Lokhu kwandisa impilo yeshelufu yomkhiqizo.
Okwesibili, kusetshenziswa kufomu le-liquid ukucindezela ngokushesha ukudla okusha okufana nenyama, izinkukhu nemikhiqizo yobisi. I-nitrogen efrijini yokudla icatshangelwa kakhulu ngokuqhathaniswa nokuqandeka kwendabuko ngoba inani elikhulu lokudla lingafakwa iqhwa ngemizuzu nje embalwa. Usebenzisa i-nitrogen ivimbela ukwakheka kwamakristalu eqhwa, okungalimaza amaseli nokudla komzimba.
Ukusetshenziswa kwezobuchwepheshe ezimbili kuvunyelwe ngaphansi komthetho wokuphepha kokudla kwezwe, okuvumela ukusetshenziswa kwe-nitrogen kuhlu lokudla, kufaka phakathi imikhiqizo yobisi ebilisiwe, ukulungela ikhofi kanye netiye, amajusi, kanye nokusika izithelo. Umthethosivivinywa awusho ngokuqondile ukusetshenziswa kwe-nitrogen ewuketshezi emikhiqizweni eseqediwe.
I-ANONNA DUTT ngumbhali omkhulu wezempilo we-Indian Express. Ukhulume ngezihloko ezahlukahlukene, kusukela emthwalweni okhulayo wezifo ezingaphenduki ezinjengesifo sikashukela kanye nomfutho wegazi ophakeme kwinselelo yezifo ezivamile ezithathelwanayo. Ukhulume ngokuphendula kukahulumeni e-Covil-19 ubhubhane futhi walandelwa eduze uhlelo lokugoma. Indaba yakhe yashukumisela uhulumeni wedolobha ukuthi atshale imali esezingeni eliphakeme labampofu futhi avume amaphutha ekubikeni okusemthethweni. I-DUTT nayo inesifiso esikhulu sohlelo lwezwe lwezwe futhi ibhale ngoMishini Osemqoka njengeChandrararayaan-2 neChandrarayaan-3, aditya L1 naseGaganyain. Ungomunye wabalingani bezindaba abangu-11 RBM balaleveva. Ubuye wakhethelwa ukubamba iqhaza ezinhlelweni zokubika zasenkulisa zesikhashana saseDart Center eColumbia University. I-Duntt yathola i-BA yakhe e-Symbiosis Institute of Media and Communications, iPune kanye ne-PG kusuka Isikhungo se-ASIAN sobuntatheli, Chennai. Uqale ukubika kwakhe umsebenzi ngezikhathi zeHindustan. Lapho engasebenzi, uzama ukukhulula izikhova zama-duolingo ngamakhono akhe olimi lwesiFulentshi futhi kwesinye isikhathi kuthatha esitezi sokudansa. … Funda kabanzi
Ikheli lakamuva le-RSS uMohan Bhagwat lisakhelweni wakamuva omakhaleni akwaSangh eNagpur labonwa njenge-BJP, isenzo esijabulisayo sokuphikiswa kanye namazwi okuhlakanipha kwisigaba sonke sezepolitiki.
