Lack of large openings and early successional conditions in close-to-nature silvicultural systems operating with small canopy gaps can be detrimental to maintenance of light-demanding tree species in ecosystems where these species are mixed with more shade-tolerant species (e.g., Neyland et al. 2012; Bauhus et al. 2013).
During the contract term, which lasts five years, UrbanVolt must pay for any maintenance of the light fixtures.
IES LM-80-08 is the approved method for measuring lumen maintenance of LED light sources [1].
Mr. Tarantino, New York City Transit's chief architect, said that cost-cutting and continuing concerns over maintenance of vault lights had eliminated them from the 72nd Street project.
Tom LaBonge, a City Council member whose district includes part of Hollywood, called the secession effort "dismemberment," and said a split could cause problems for Hollywood residents that they could not imagine, like disrupted maintenance of traffic lights, water flow, fire response and power.
The Coast Guard's deed required the construction and maintenance of beacon lights or other navigational aids as part of the Coast Guard's new training facility.
Considering that the expansion and organisation of the apical surface occurs by different mechanisms in vertebrates and Drosophila – formation of membrane discs vs microvilli – these proteins seem to control a very basic, evolutionarily conserved cell biological function, required for the maintenance of apical, light-sensing membrane integrity.
Improved housekeeping with such factors as furnace maintenance, adjustment of lighting system operations, use of daylight, improving space conditions for lighting, and improving lamp and fixture efficiency are quantifiable measures of energy conservation.
In particular, the assessment of blanket and divertor maintenance, in light of the expected radiation conditions and availability, has elaborated the need for a very different approach from that of ITER.
