British NVC community OV19

British NVC community OV19 (Poa annua - Matricaria perforata community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of six communities characteristic of gateways, tracksides and courtyards.

This community is found throughout the lowlands of Britain wherever there is suitable habitat.

There are five subcommunities.

Community composition

The following constant species are found in this community:

There are no rare species associated with the community.

Distribution

This ephemeral community is widely distributed throughout the lowlands of Britain. Characteristic habitats are on farm tracks, around gateways where trampling is only moderate, and on verges alongside roads, wherever disturbance and spray-wash from vehicles prevents the development of a closed perennial sward.

Subcommunities

There are five subcommunities:

  • the Senecio squalidus - Epilobium angustifolium subcommunity
  • the Lolium perenne - Capsella bursa-pastoris subcommunity
  • the Atriplex prostrata - Chenopodium album subcommunity
  • the Chamomilla suavolens - Plantago major subcommunity
  • the Elymus repens subcommunity

Larmor formula

Gives the total power radiated by an accelerating, nonrelativistic point charge A Yagi–Uda antenna. Radio waves can be radiated from an antenna by accelerating electrons in the antenna. This is a coherent process, so the total power radiated is proportional to the square of the number of electrons accelerating. Not to be confused with the phenomenon in nuclear magnetic resonance known as Larmor precession. In electrodynamics, the Larmor formula is used to calculate the total power radiated ...
