Unugyada cabbiraadda

Halbeegyada cabbirku waa qalabka loo isticmaalo in lagu qiyaaso waxyaabo kala duwan, ilaa xad in tirooyinka laftoodu ay oggolaadaan oo keliya in lagu tiriyo waxyaalahaas kala goyn kara unugyo. Ma aha wax kasta oo ay dadku damacsan yihiin inay cabbiraan laguma kala saari karo unugyo, xitaa iyadoo lagu darayo suurtagalnimada jajabyada: waxaa lagama maarmaan ah xaaladaha qaarkood in la soo bandhigo qaababka cabbiraadda kala duwan.

Cutubyadani waxay dhammaystiraan qiyamka miisaanka leh, waxayna guud ahaan ka kooban yihiin hal ama laba eray oo lagu xusay dhammaadka tirada. Aqoonta ku saabsan halbeegyada cabbirka ayaa suurtogal ka dhigaya in la fahmo nooca unug ee aan ka hadlayno. Si kastaba ha ahaatee, gudaha waxa lagu cabirayo baaxadda waxaa jira tibaaxyo kala duwan, taas oo ka dhigaysa mid lama huraan ah habka beddelidda, kuwaas oo aqoontu mararka qaarkood ku kooban tahay saynisyahanno khabiir ku ah mawduuca.

Taasi waa sababta, inta bulshada inteeda badani ay khusayso, waa wax caadi ah in halbeegyada cabbirka lagu soo bandhigo hal goob oo keliya, isla gobolka gudahiisa: si kastaba ha ahaatee, isku dhufashada hal unug, oo aan ka koobnayn laba kala duwan (garaam, milligram, iyo kiilogaraamku waa qayb ka mid ah halbeegga cabbirka). Marka qofka aan wax badan ka aqoon halbeegyada cabbirka uu u safro meel kale, waa iska caadi inuu ku wareero qiyaasta tirada.

Hase yeeshee, waxaa la isku raacay in la soo bandhigo a nidaamka caalamiga ah ee halbeegyada si adduunku u yeesho hab u gaar ah oo lagu cabiro tiro cayiman. Waxaa la isku raacay, markaa, in la diyaariyo liis ka kooban toddoba cutub oo cabbir ah: mid dherer ah, mid cuf, mid waqti, mid koronto xoog leh, mid heerkulka heerkulka, mid ka mid ah tirada walaxda iyo mid xoogga iftiinka .

Labaatan tusaalood oo ah halbeegyada cabbiraadda ayaa halkan lagu faahfaahinayaa, oo tilmaamaya kuwa qayb ka ah nidaamka caalamiga ah ee cutubyada. Kiisaska kale, xiriirka lala sameeyay midka caalamiga ah ayaa la xusi doonaa.
