In direct marketing, there is a direct interaction of the customers with the seller without any intermediaries. Here, the role of the intermediaries is nil. The medium used is more direct using telephone, mail, internet where the seller can directly reach out to the consumer. Examples of such marketing include telemarketing, email, voicemail marketing, door-to-door selling etc. This kind of marketing is more time saving as the problem of distance which may otherwise exist between the buyer and seller is eliminated and is also cost effective as it minimizes commuting costs.

A cumulene is a hydrocarbon with three or more cumulative double bonds. They are analogous to allenes, only having a more extensive chain. The simplest molecule in this class is butatriene, which is also called simply cumulene.

The carbons on the ends are sp² hybridized, with a p-orbital for the 'second' bond in the double bond with their neighboring carbons.

They have those sp² orbitals overlapping with the s from the hydrogen, and they have a p overlapping in the pi bond with the neighboring carbon. They also have a sigma bond with the neighboring carbon I'll get to.

The middle carbons each have two pi bonds with their neighbors, leaving sp hybridiaztion for the rest. So they have sp/sp² with the end carbons, and sp/sp with each other. (And they also have p/p in the pi bonds).

All orbital overlappings in Cumuene are :

* s/sp²

* p/p

* sp/sp²

* sp/sp

Object Repository means not a collection of objects

it's a common repository for all the people (testing, developers) for seeing all the data in single login.

for example QA wants to see 5 testers works then he goes  to each person login and see the data. It's very difficult job. for this we can use Object Repository.
