	tower. The Columbia Encyclopedia, Sixth Edition. 2001-05
		There the bell tower, or campanile, stood detached from the church building itself; another example is the celebrated bell tower at Pisa (1174).
		The relatively simple Romanesque towers generally had square or round shafts with many blind arcades in horizontal tiers and were topped by a simple octagonal or conical spire.
		Towers of extreme lightness and intricacy were developed in the late Gothic period, as in the cathedrals at Rouen, Vienna, and Antwerp.

	Columbia News ::: Damage to Buildings Near WTC Caused by Falling Debris and Air Pressure Wave, Columbia Seismologists ...
		Rather, the buildings around the Twin Towers were impacted both by the kinetic energy of falling debris and by the pressure exerted on the buildings by a dust- and particle-laden blast produced by the collapse.
		The subsequent collapse of the towers, on the contrary, registered magnitudes of 2.1 and 2.3, comparable to the small earthquake that occurred beneath the east side of Manhattan on January 17, 2001.
		The authors also noted that as seen in television images, the fall of the towers was similar to that of a pyroclastic flow down a volcano, where hot dust and chunks of material move in a dust/mud matrix down the volcano's slope.

	Open Letter To World Trade Center Investigators
		The towers were literally "blasted" off their footings at the beginning, and during the first phase, of their respective collapses.
		The fact that the towers were seen "jumping" immediately before the collapse is documented on film by a helicopter camera that witnessed that event.
		Scientists who continue to obfuscate and refuse to investigate the clear evidence of explosions in the towers will undoubtedly be considered by honest investigators, the public, and history, to be part of the cover-up.

	The World Trade Center Demolition and the So-Called War on Terrorism at American Buddha Online Library
		The Twin Towers collapsed in a very strange manner, leaving almost nothing but metal fragments from the outer shell and huge quantities of fine ash and dust, without the central steel columns from the lower sixty floors either standing or fallen.
		In such a case, it might be held, better to demolish one or both of the towers in a controlled manner so as to minimize death and destruction in the surrounding area.
		Since it was this very same FEMA which took charge of the "investigation" into the WTC collapse (and is about to release a report claiming that the fires caused the collapse) one might be forgiven for suspecting that their "investigation" has been something less than an unbiased attempt to discover the truth of what happened.

	The Legal Landscape When a Tower Collapses
		Generally speaking, owners and those responsible for maintaining and leasing towers have a legal duty to act reasonably to prevent and warn of those dangers which they know or should know and are not openly obvious to those working on or near towers for a particular business purpose.
		Further, it was asserted the tower owner had actual knowledge of the danger or condition resulting in the deaths and failed to warn of such danger.
		Tower contractors have three sets of concerns in the event of an accident, including: (1) contractual and liability claims from its customer, the owner; (2) liability claims of those who did not hire the contractor, including lessees and personal injury claims; and (3) governmental oversight from OSHA or other applicable institutions.

	Opinion and Order: Civil Action No. 00-2436 (PLF) [American Tower v. Anthony Williams, Mayor of the District of ...
		In Count One of its amended complaint, American Tower asserts that the District of Columbia's October 10, 2000 decision to rescind its building permit was arbitrary and capricious and that it violated plaintiff's vested property interests by singling it out for adverse treatment in violation of the Equal Protection Clause.
		American Tower does not argue with defendants' assertion that a violation of the Height Act would constitute a rational basis to rescind its permit.
		American Tower suggests that the Moratorium Act violates plaintiff's due process rights because it unfairly authorizes the Mayor to halt construction of the tower and to create a regulatory scheme that could be used later to block the resumption of construction on the tower.

		The towers, when equipped with their tri-blades in place on the rotor, are roughly the same width as the wingspan of a Boeing 747 aircraft.
		Areas with a larger cluster of wind towers are determined based on a variety of factors, such as, proximity to roads so that they can be serviced easily; acceptability of the location by the landowner; and sufficient air movement to move the turbines and generate the electricity.
		Landowners and or farmers within at least a one-half mile radius of a proposed tower should be notified by the sponsoring entity of the tower.

	Sizing of Packed Towers in Acid Plants
		A result of the unusual features of packed towers employed in acid plant service is that truly applicable design data are not readily available and that discrepancies reveal themselves when the designs of different technology suppliers are compared.
		Engineers involved in sizing towers have at their disposal a number of different techniques for tower sizing, ranging from rules of thumb based on gas velocity and irrigation rate, to dated theoretical work in the handbooks, to software programs from packing vendors, and finally to proprietary in-house design techniques.
		For a three foot tower, the packing density would be ninety seven percent of that of the reference tower, while for a twenty foot tower, the actual packing density would approach one hundred and ten percent of the reference case.

	List of masts - Wikipedia, the free encyclopedia
		While commonly used on sailing ships as support for sails, radio masts and towers are also used for telecommunication equipment such as radio antennas, also known as aerials in the UK.
		There is often crossover in term usage as some skyscraper use the tower term, some towers use the mast term, and ironically 'skyscraper' has some word heritage from references to high sailboat masts.
		Top masts are ranked by pinnacle height; in the case of a tie, the older structure is ranked as higher.

	Scientific American: When the Twin Towers Fell (commented)
		According to press reports, the original asbestos cementitious fireproofing applied to the steel framework of the north tower and the lower 30 stories of the south were removed after the 1993 terrorist truck bombing.
		Though the Boeing 767s airliners that hit the towers were somewhat larger than the Boeing 707 (maximum takeoff weights: 395,000 pounds versus 336,000 pounds) the structures were designed to resist, the planes carried a similarly sized fuel load as the older model—about 24,000 gallons versus 23,000 gallons, according to Kausel.
		Actually the "collapses" of WTC towers 1, 2, and 7 are the first examples in history of steel-framed high-rises undergoing total collapse from any cause or combination of causes other than controlled demolition, a fact conspicuously absent from this article.
