Itandukaniro riri hagati y'imikandara n'imikandara y'izuba

1. Itandukaniro ry'uburemere
Ugereranyije n'amasambu, amasambu y'izuba azaba ari amasambu yoroheje, andi akaba ari amasambu y'ibikoresho bitari iby'icyuma.
2, Ibikoresho bitandukanye
Igitambaro n'ibikoresho by'umutaka ni umwihariko, imikorere yo kurinda izuba ni myiza cyane, byongeye kandi, ubushobozi bwo kuziba imirasire ya ultraviolet nabwo burakomeye cyane. Umutaka w'izuba ushingiye ku kugaragaza imikorere yo gukingira ubushyuhe bwa ultraviolet bw'izuba, mu gihe umutaka wo muri rusange udakoresha amazi.
3, Amabara atandukanye
Amasamburo ashobora kuba yoroheje mu ibara, kuko adapfa imvura, mu gihe amasamburo y'izuba muri rusange aba yijimye mu ibara, ahanini kugira ngo arinde imirasire y'izuba.
Amakuru yagutse
Itandukaniro riri hagati y'umutaka urinda izuba n'umutaka urinda izuba
Itandukaniro rikomeye riri mu mikorere: akazi kanini k'imitaka ni ukurinda umuyaga n'imvura, mu gihe akazi kanini k'imitaka irinda izuba ni ukurinda izuba n'imirasire ya UV no kurinda ubuzima bw'uruhu. Icya kabiri, itandukaniro riri hagati y'imitaka n'imitaka irinda izuba riri mu bikoresho byo gukora no mu mikorere: imiterere rusange y'imyenda ifata nk'umutaka ifatwa nk'aho idapfa amazi, mu gihe imiterere y'imitaka irinda izuba iri ahanini ku bikoresho birinda UV, no mu bukorikori bwiza, hari imiterere myinshi myiza yo gucapa no gusiga amarangi.
Byongeye kandi, umutaka rusange, haba izuba n'imvura, ni umutaka w'izuba n'umutaka w'izuba, ariko muri rusange ingaruka z'igicucu ziba nkeya gato, ingaruka rusange zo kurinda izuba. Niba ari ahantu hagwa imvura, koresha umutaka w'izuba; niba ari ahantu humutse, ushobora gukoresha umutaka w'umwuga w'isuku y'izuba.
Ingaruka z'Umuco
Mu Bwongereza, imitaka yakoreshwaga kugeza mu kinyejana cya 18. Umutaka wa Berners wigeze gukoreshwa n'abagore, bigaragaza ko umugore akunda urukundo. Gufata umutaka uhagaze bivuze ko umuntu agomba gukomera mu rukundo; gufata umutaka ufunguye mu kuboko kw'ibumoso bivuze ngo “Nta mwanya mfite wo kwisanzura ubu”. Kuzunguza umutaka buhoro buhoro bivuze ko nta cyizere cyangwa kutizera; gupfuka umutaka ku rutugu rw'iburyo bivuze ko adashaka kongera kukubona.
