Isticmaalka qaybta godan ee laba jibbaaran iyo leydi
Tuubada laba jibbaaran waa agabka ugu muhiimsan uguna muhiimsan nidaamyada taageerada sawir-qaadista sababtoo ah waxqabadkeeda qaab-dhismeedka ee aadka u wanaagsan iyo kharash-oolnimada. Tuubooyinka birta kaarboon ee nooca Youfa ayaa si weyn loogu isticmaalaa qaab-dhismeedka taageerada qorraxda, iyo iibka kulul ee Bariga Dhexe iyo Afrika.
Tuubooyinka qaabaysan ee afar geesoodka ahwaxaa si weyn loogu isticmaalaa soo saarista biraha sawir-qaadista sababtoo ah sifooyinkooda farsamo ee aadka u wanaagsan iyo xasilloonida qaab-dhismeedka. Biraha sawir-qaadista waa qayb muhiim ah oo ka mid ah nidaamka soo saarista korontada sawir-qaadista qorraxda, oo inta badan loo isticmaalo in lagu taageero laguna hagaajiyo muraayadaha qorraxda. Isticmaalka tuubooyinka afargeeslaha ah ee afargeeslaha ah sida agabka taageerada waxay leedahay faa'iidooyinka soo socda:
Awood sare:Qaabka isgoyska ee tuubada leydiga ah wuxuu siiyaa xoog sare marka uu la kulmo culaysyo dhaadheer iyo kuwo isdhaafsan, taasoo si wax ku ool ah uga hortagta arrimaha dibadda sida cadaadiska dabaysha iyo cadaadiska barafka.
Xasillooni wanaagsan:Naqshadeynta qaab-dhismeedka tuubada laba jibbaaran waxay hubineysaa xasillooni wanaagsan ka dib rakibidda, taasoo yaraynaysa isbeddelka ay sababaan xoogagga dibadda.
Si fudud loo farsamayn karo:Habaynta tuubooyinka laba jibbaaran iyo kuwa afargeeslaha ah waa mid fudud, waana la jari karaa, la alxan karaa, dusha sarena waa la daweyn karaa iyadoo loo eegayo baahiyaha dhabta ah, taasoo ka dhigaysa rakibidda iyo dayactirka mid ku habboon.
Fudud:Marka la barbardhigo agabka kale, tuubooyinka afargeeslaha ah ee laba jibbaaran ayaa miisaankoodu ka fudud yahay, taasoo ka dhigaysa kuwo fudud in la raro oo la rakibo, waxayna yaraynaysaa kharashka dhismaha.
Iska caabbinta daxalka:Tuubooyinka laba jibbaaran ee laba jibbaaran ee lagu sameeyay daaweynta dusha sare waxay leeyihiin iska caabin wanaagsan oo daxalka ah waxayna la qabsan karaan xaaladaha cimilada ee kala duwan, iyagoo kordhinaya cimrigooda adeegga.
Dhaqaalaha:Qiimaha wax soo saarka ee tuubooyinka laba jibbaaran iyo kuwa leydiga ah waa mid hooseeya, oo ku habboon codsiyada baaxadda weyn, waxayna si wax ku ool ah u yareyn kartaa kharashka guud ee nidaamyada korontada dhaliya ee sawir-qaadista.
Adeeg wanaagsan oo iibka kadib ah:Summada Youfa waxay ku leedahay sumcad wanaagsan suuqa, iyadoo bixisa adeeg tayo sare leh oo iibka kadib ah si loo hubiyo qanacsanaanta macaamiisha inta la isticmaalayo.
Sidaa darteed, isticmaalka tuubooyinka labajibbaaran ee leydi ah ee ku jira taageerooyinka sawir-qaadista ma aha oo kaliya inay hagaajiyaan waxqabadka taageerooyinka, laakiin sidoo kale waxay kor u qaadaan horumarinta warshadaha sawir-qaadista.
