<prompt> Fingqa isihloko: Ngokuqondene nokushefa, abafana ngokuvamile bafundiswa uyise noma umfowabo omdala. Kodwa lokhu kusho ukuthi imikhuba emibi ingadluliselwa ezizukulwaneni ngezizukulwane. Manje usosayensi oyinhloko wakwaGillette uveze isayensi esekelwe ekushefeni kuhlanganise nendlela izinwele eziziphatha ngayo, ukuthi kungani ukugeza isikhumba kubaluleke kangaka nokuthi kungani kungafanele neze, noma nini ushaye isisefo sakho esisinki. Futhi uxazulula impikiswano yokuthi kufanele yini uhambe nomkhathi noma uphambane nawo. Skrolela phansi ukuze ubone ividiyo. Ngokwesilinganiso, izinwele zesilevu zinobubanzi obungamamilimitha ayishumi. Lapho umile, izinwele ziba ngu-130 microns ububanzi kwesobunxele kodwa lapho zinamanzi lokhu kukhula kube cishe ngu-150 microns. Ukugeza ubuso ngaphambi kokushefa kwandisa indawo engadlula kuyo izindwani, kusho usosayensi oyinhloko weGillette uKristina Vanoosthuyze. UDkt. Kristina Vanoosthuyze usebenze emkhakheni we-Gillette Shaving Technology e-Innovation Centre e-Reading eminyakeni eyisishiyagalolunye edlule. Njalo ekuseni amavolontiya angu-80 aya esikhungweni futhi aphuce phambi komshini wokuthwebula amafilimu ohlanganisa amalensi okukhulisa, amakhamera anejubane elikhulu nokukhanya okukhethekile okunamandla amakhulu. Lokhu kuye kwembula indlela insingo esika ngayo izinwele, futhi ezimotweni ezinamasondo amaningi, insingo yokuqala idonsa izinwele phezulu, eyesibili iyazisika, insingo yesithathu isebenza ngendlela efanayo neyokuqala, njalonjalo. Kweminye yemikhiqizo yabo, iGillette inikeza nomsebenzi wokudlidliza ophakamisa izinwele ngokwengeziwe futhi unciphise ukungqubuzana okubangelwa ama-blade. Le mifanekiso iye yembula futhi umehluko phakathi kwesikhumba esomile nesinamanzi nezinwele zesilevu. Nsuku zonke izisebenzi zokuzithandela ezingu - 80 zishefa phambi komshini ohlanganisa ama - magnifying lens namakhamera asheshayo. Lokhu kuye kwembula indlela ummese osika ngayo izinwele. Ezimodeleni ezinama-blade amaningi, i-blade yokuqala idonsa izinwele phezulu, eyesibili izigaxe, i-blade yesithathu idonsa njalo njalo. Lapho isikhumba sinamanzi, naso siqina isithombe sesikhumba siboniswa ngaphambi kokugeza kwesobunxele nangemva kokugeza kwesokudla. Lokhu kuveza ingxenye enkulu yezinwele ekhaleni. Ngenxa yalokho uDkt.  <response>: UDkt. Kristina Vanoosthuyze uhlola imikhuba yokushefa yamadoda angu-80 nsuku zonke esebenzisa amakhamera anejubane eliphezulu esikhungweni seGillettes Innovation Centre eReading. Ukuqoshwa kwakhe kwembula lokho okwenzekayo lapho imimese eminingi ihamba phezu kwezinwele. I-electron microscopy ibonisa umehluko phakathi kwesikhumba esomile nesimanzi. Usosayensi wakwaGillette uye waveza nokuthi yini okufanele yenziwe nokungafanele yenziwe lapho umuntu egunda. Uncoma ukuba abantu bathathe ishawa ngaphambi kokushefa, futhi basebenzise imivimbo emincane. Ukuhlolwa kuye kwabonisa ukuthi abantu kufanele baqale ngokushefa bebheke izinwele. Futhi izinsimbi zokugunda akufanele neze zikhishwe esinkini ngaphansi kwanoma yiziphi izimo.
