Gear finishing operation is called Burnishing.

The support cells of the nervous system are Glia, also called glial cells or neuroglia. In the central nervous system, there are four types of supporting cells. They are ::

* Astrocytes

* Microglial cells

* Ependymal cells

* Oligodendrocytes

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

If for a short period of time circuits goes to some different logic level then it is spposed to have then it is called static hazard. e.g., If the final logic value of output of given circuit becomes one vent if if is supposed to be zero then it is called static-0 Hazard and vice versa. Dynamic Hazard is the one in which the circuit output goes to some other logic level more than once then finally settling down to some appropriate level.

In all plants and animal cells chromosomes are located in the Nucleus of the cells.

The Chromosomes are thread like structures present in the nucleus of the cells which are made up of proteins and a single molecule of DNA.

Their function is to carry the characteristic features of parent cells to daughter cells.
