Abantu benshi ntibabizi, ariko abantu bamwe allergic kuriibyuma.Dukurikije amakuru yibanze yatangajwe mu kiganiro gishya, icumi ku ijana by'abatuye Ubudage ni allergic kuri nikel.
Ariko imiti yo kuvura ikoresha nikel.Amavuta ya Nickel-titanium agenda akoreshwa nk'ibikoresho byo gutera umutima-mitsi mu buryo bworoshye, kandi nyuma yo kuyitera, ayo mavuta arekura nikel nkeya kubera ruswa.Ese ni akaga?
Itsinda ry’abashakashatsi bo muri Jena, Prof. Rettenmayr na Dr. Andreas Undis, batangaza ko insinga zakozwe muri nikel-titanium alloy zisohora nikel nkeya cyane, ndetse no mu gihe kirekire.Igihe cyo kwipimisha ibyuma ni iminsi mike, nkuko leta yabisabye kugirango yemererwe kwivuza, ariko itsinda ry’ubushakashatsi bwa Jena ryabonye nikel irekurwa amezi umunani.
Ikigamijwe mu bushakashatsi ni insinga yoroheje ikozwe muri nikel-titanium ya superelastique, ikoreshwa, urugero, muburyo bwa occluder (ibi ni imiti ikoreshwa mubuvuzi bwo gusana inenge ya septal).Ubusanzwe includer igizwe ninsinga ebyiri ntomesh"Umbrellas" hafi yubunini bwigiceri.Gutera superelastique birashobora gukururwa muburyo bworoshye muburyo bworoshye hanyuma bigashyirwa muri catheter yumutima.Undisch yagize ati: "Muri ubu buryo, ibiyobora bishobora gushyirwaho uburyo bworoshye bwo gutera."Byiza, gutera bizaguma kumurwayi imyaka cyangwa imyaka mirongo.

Undis hamwe numunyeshuri wa dogiteri Katarina Freiberg bashakaga kumenya uko byagendekeye insinga ya nikel-titanium muriki gihe.Bakoresheje insinga z'icyuma hamwe nuburyo butandukanye bwo gukanika no gukoresha amazi mumazi ya ultrapure.Nyuma bagerageje gusohora nikel bashingiye kumwanya wagenwe.
Undish agira ati: “Ibi ntabwo ari ibintu na gato, kubera ko icyuma cyarekuwe gikunze kuba ku rugero rwo gutahura.”, yatsinze mugutezimbere uburyo bukomeye bwo gupima nikel irekura.
Undisch yavuze muri make ibyavuyemo ati: "Muri rusange, mu minsi ya mbere n'ibyumweru bya mbere, bitewe no kubanza kuvura ibikoresho, umubare munini wa nikel urashobora kurekurwa."Nk’uko abahanga mu bumenyi babitangaza, ibi biterwa nuburemere bwimashini yatewe mugihe cyo kubaga.“Guhindura ibintu byangiza urwego ruto rwa oxyde itwikiriye ibikoresho.Igisubizo ni kwiyongera kwintangirironikelgukira. ”nikel dukuramo ibiryo burimunsi.
Muri Science 2.0, abahanga ni abanyamakuru, nta kubogama kwa politiki cyangwa kugenzura inyandiko.Ntidushobora gukora ibi byonyine, nyamuneka kora uruhare rwawe.
Turi abadaharanira inyungu, Igice cya 501 (c) (3) isosiyete yamakuru yubumenyi yigisha abantu barenga miliyoni 300.
Urashobora gufasha gutanga umusanzu utishyuye uyumunsi kandi impano yawe izajya 100% muri gahunda zacu, nta mushahara cyangwa biro.
