At larger airports, pilots receive their flight plan clearances from a "clearance delivery" frequency, communicate on taxiways with a "ground" frequency, and get takeoff and landing clearance from the "tower" frequency.
The study demonstrates how land use change (LUC) which also includes land cover, the local land use mix index (LLUM) and land use frequency (LUF) can be used as indicators of objective land use sustainability.
Even before the creation of the Bulgarian state, the empires of ancient Rome, Greece, and Byzantium were strong presences, and people and goods traveled the land with frequency.
These authors observed that the abandonment of cultivated fields induces a significant decrease in land slipping frequency, and in sediment delivery.
The brief telephone baseline assessment (adapted from Hodgins et al. 2009) will include a demographic profile (age, sex, education, marital status, income, ethnicity and racial status, employment status) and a gambling, mental health and treatment history including a timeline interview of types of gambling (online, land-based), frequency, and money spent for the past three months [ 48, 49].
ELIZABETH, N.J. — The emotional blows had been landing with increasing frequency for Rudolph Zurick.
As one of the most sensitive and vulnerable systems, coastal zones' areas of concern include sea level rise, land loss, the frequency of maritime storms, flooding and responses to sea level rise (Rubinoff et al. 2008; Woodruff et al. 2013).
This can be explained by differences in surface topography (for example, elevation of land) and inundation frequency and duration inundation is more frequent and lasts longer in the downstream region than in the upstream region.
The report describes the very high probability by the late 21st century of increased temperatures and more heat waves over most land areas; increased frequency, intensity, and/or amount of heavy precipitation; increased intensity and duration of drought; increased intense tropical cyclone activity; and increased extreme high sea level.
