Local Anesthetic

A local anaesthetic (LA) is a medication that causes the absence of all sensations (including pain) in a specific body part without loss of consciousness, as opposed to a general anaesthetic, which eliminates all sensations in the entire body and causes unconsciousness. Local anaesthetics are most commonly used to eliminate pain during or after surgery.

Infrastructure as a Service

Infrastructure as a service (IaaS) is a cloud computing service model using which computing resources are supplied by a cloud services provider. The IaaS vendor provides the storage, network, servers, and virtualization (which mostly refers, in this case, to emulating computer hardware). This service enables users to free themselves from maintaining an on-premises data centre.

Ultra Low Emission Zone

The Ultra Low Emission Zone (ULEZ) is an area in London, England, where an emissions standard-based charge is applied to non-compliant road vehicles. Plans were announced by London Mayor Boris Johnson in March 2015 for the zone to come into operation in September 2020. Sadiq Khan, the subsequent mayor, introduced the zone early on 8 April 2019. The zone initially covered Central London, the same area as the existing London congestion charge and raised £224 million in 2022.
