Guterura no gukurura imishumi, umunyururu wo kuzamura,umunyururu mugufi, guterura umunyururu uzenguruka,Urunigi rw'icyiciro cya T, urunigi rwa DAT rw'icyiciro,Umunyururu wa DT w'icyiciro cya mbere, DIN EN 818-7umuyoboro mugufi wo guterura,umuyoboro mwiza wo gupakira,umunyururu w'icyuma gikozwe mu byuma
Porogaramu
Guterura no gukurura imitsi, guterura imizigo, gufata imizigo
Nk’uruganda rukora imiyoboro y’ibyuma bizunguruka mu gihe cy’imyaka 30, uruganda rwacu rumaze igihe kinini rukora kandi rukora mu gihe cy’ingenzi cy’iterambere ry’inganda z’abashinwa mu bijyanye no gucukura imiyoboro y’amashanyarazi (cyane cyane ibirombe by’amakara), guterura ibintu biremereye, no gutwara ibintu mu nganda ku miyoboro y’ibyuma bizunguruka ifite imbaraga nyinshi. Ntiduhagarara ku kuba uruganda rukora imiyoboro y’ibyuma bizunguruka mu Bushinwa (rutanga toni zirenga 10.000 buri mwaka), ahubwo dukomeza guhanga no guhanga udushya tudahagarara.
