Complex vascular tissue involved in the-transport of nutrients throughout a plant.

Where three or more plant organs are arranged around a node.

One of the many lines which can be seen on the surface of a leaf, marketing the position of the vascular bundle.

Vibration Dose Value (VDV) is a metric used in vibration monitoring. It is calculated by taking the fourth root of the integral of the fourth power of acceleration after it has been frequency-weighted. The frequency-weighted acceleration is measured in m.s-2 and the time period over which the VDV is measured is in seconds. This yields VDVs in m.s-1 [..]

The Air Quality Strategy for England, Scotland, Wales and Northern Ireland. This describes the plans drawn up by the Government and the devolved administrations to improve and protect ambient air quality in the UK in the medium-term. The Strategy sets objectives for the main air pollutants to protect health.

The troposphere is the lowest portion of the Earth’s atmosphere, which includes the portion where air pollutants are emitted, mixed, react with each other and where people are exposed to their effects.

Toxic organic micro pollutants (TOMPs) are produced by the incomplete combustion of fuels. They comprise a complex range of chemicals some of which, although they are emitted in very small quantities, are highly toxic or carcinogenic. Compounds in this category include: PAHs (Polycyclic Aromatic Hydrocarbons); PCBs (PolyChlorinated Biphenyls); diox [..]

Sustainable Urban Drainage Systems (SUDS) are designed to reduce the potential of flooding on new and existing urban developments. Unlike traditional urban stormwater drainage systems, they also help to protect and enhance ground water quality. Sustainable Drainage System (SuDS) are the same as SUDS.

Stalkless or apparently so. Often used to describe how a leaf or fruit is attached to a plant stem.
