HEC ee dahaarka biyaha ku salaysan

soo bandhig:

Sanadihii la soo dhaafay, daaha-ku-salaysan biyaha ayaa helay caan sababtoo ah saaxiibtinimo deegaanka iyo isku-dhafka dabiiciga ah ee hooseeya (VOC). Mid ka mid ah maaddooyinka muhiimka ah ee door muhiim ah ka ciyaara qaabaynta daahan biyaha ka soo baxa ee waxqabadka sare leh ayaa ah wax-ku-kordhinta dhuxusha oo tayo sare leh (HECs).

1. Faham dahaarka biyaha ku salaysan:

A. Dulmar daahan biyaha ku salaysan

b. Faa'iidooyinka deegaanka ee daboolka biyaha ku salaysan

C. Caqabadaha ku jira samaynta dahaarka biyaha ka soo baxa ee waxqabadka sarreeya

2. Horudhac wax-ku-oolnimada sare leh ee samaynta filimada (HEC):

A. Qeexida iyo sifooyinka HEC

b. Horumarka taariikhiga ah iyo horumarinta HEC

C. Muhiimadda ay leedahay isku-duubnida dahaarka biyaha ku salaysan

3. Doorka HEC ee geedi socodka isbahaysiga:

A. Hababka samaynta isbahaysiga iyo filimada

b. Saamaynta HEC ee isku-dhafka walxaha iyo daacadnimada filimka

C. Hagaajinta adhesion iyo adkeysiga HEC

4. Kobcinta waxqabadka HEC:

A. Samaynta filimada iyo wakhtiga qalajinta

b. Saamaynta heerka iyo muuqaalka

C. Saamaynta adkaanta iyo xidhashada caabbinta

5. Dhinacyada joogtaynta ee HEC ee dahaadhka biyaha ku salaysan:

A. Hoos u dhigista VOC iyo saamaynta deegaanka

b. U hoggaansanaanta sharciga iyo heerarka caalamiga ah

C. Falanqaynta meertada nolosha ee daahan biyaha ku salaysan ee HEC

6. Codsiyada HEC ee warshadaha kala duwan:

A. Dahaarka Dhismaha

b. Dahaarka baabuurta

C. Dahaarka warshadaha

d. Dahaarka alwaaxda

7 Caqabadaha iyo horumarka mustaqbalka:

A. Caqabadaha hadda jira ee diyaarinta HEC

b. Isbeddellada soo baxaya iyo hal-abuurka

C. Rajada mustaqbalka ee HEC ee dahaarka biyaha ku salaysan

8. Daraasado kiis iyo tusaaleyaal:

A. Codsiga guusha leh ee HEC ee xaaladaha dhabta ah

b. Falanqaynta isbarbardhigga iyo waxyaabaha kale ee samaynta filimada

C. Casharradii La Bartay iyo Talooyinka Horumarinta

Gabagabadii:

Si loo soo koobo qodobbada muhiimka ah ee looga hadlay maqaalkan, waxaan muujineynaa doorka muhiimka ah ee HEC si loo hagaajiyo waxqabadka iyo joogtaynta daboolka biyaha. Suurtagalnimada cilmi baaris iyo horumarin dheeraad ah oo ku saabsan aaggan ayaa la muujiyay.
