These roots have some ability to absorb water and nutrients, but their main function is transport and to provide a structure to connect the smaller diameter, fine roots to the rest of the plant.

Expanded diameter is an indication of the size of the wound cavity, penetration depth shows if vital organs could be reached by the bullet, and weight retention indicates how much of the bullet mass fragmented and separated from the main body of the bullet.

The. 22 LR and related rimfire. 22 cartridges are also unique because these are the only mainstream cartridges using a two-diameter bullet, where external diameter of the case is the same as diameter of the forward portion of the bullet and where the rearward portion of the bullet, which extends into the case, is necessarily smaller in diameter than the main body of the bullet.

The second category was effected with one or more “ main ropes ” or “ honnawa ” which like the torinawa could be any one of many different lengths, but was a proper hemp rope, possibly six or more millimeters in diameter and as much as eighty feet long — which was used to provide a more secure, long-term binding than is possible with the torinawa for transportation to a place of incarceration, restraint at legal proceedings, and — in the case of particularly severe crimes — for the public display of the prisoner prior to execution by such methods as beheading, crucifixion ( i. e., the prisoner was displayed tied to a cross before spears were driven through the body ), or, in arson convictions, death by fire.

The main portion has a stone foundation, and is held up by the same virgin timber, each in diameter, and running the entire width of the house.

In 1904, Beemer carried out further modernization of the village water works by installing new, larger underground pipes in many parts of town, additional fire hydrants, and building a large water standpipe 10 feet in diameter and 85 feet in height that would become an icon of Beemer's main street for decades to come.

The spring aquifer held a large quantity of water due to the great number of fractures, solution channels, and interstices in the rocks and underlying sands, although the aeral extent of the Big Spring sink is estimated to be only in diameter, with the main area only wide and almost circular, with some ellipticity trending towards the west.

The emplacement drifts ( smaller diameter tunnels branching off the main tunnel ) where waste would have been stored were not constructed since they required a construction authorization by the Nuclear Regulatory Commission.

The main strung cables are in diameter and each carries 13, 800 tonnes of the bridge's load by suspending 11, 618 diameter high tensile wires.

A 400 gallon water tank ( 300 gallons on 4x4 ) was installed, which fed small diameter hoses on each side of the vehicle to give an immediate " first aid " capacity to fight a fire whilst the main hoses were connected and brought into use.

Gage survived an 1848 accident in which an iron rod 1¼ inches in diameter was driven through his head, destroying most or all of his left frontal lobe.

The flowers have a five-lobed funnel-shaped corolla, up to 7 cm ( 2. 5 in ) long and 5. 5 cm ( 2 in ) diameter, each lobe with a notched apex, velvety in texture, either violet or orange, and have contrasting darker stripes along each petal.

The flowers are produced in clusters of 10-50 together ; each flower is bright red, 1-3 cm diameter, with a deeply five-lobed corolla, with each lobe further split into two smaller lobes, which creates a general shape similar to the Maltese Cross to which it owes its name.

It was surrounded by the heart, left lower lobe of the lung, aorta, esophagus, and diaphragm, and had been 1. 8 cm in diameter 7 years before.

In the observations at 4.3 mm ( Coates, 1959 ), the diameter of the antenna beam, 6'.7, was small enough to allow resolution of some of the larger features of the lunar surface, and contour diagrams have been made of the lunar brightness distribution at three lunar phases.

A 116. 8 cm diameter high-gain parabolic antenna was mounted at the top of the frame as well.

The beam has to have a large diameter so that only a small portion of the beam misses the sail due to diffraction and the laser or microwave antenna has to have a good pointing stability so that the craft can tilt its sails fast enough to follow the center of the beam.

Uplink was via S band A two-axis steerable high-gain parabolic dish antenna with a diameter of approximately 1. 5 m was attached at one edge of the orbiter base, and a fixed low-gain antenna extended from the top of the bus.

The microwave radiometer, the infrared radiometer and the radiometer reference horns were rigidly mounted to a 48 cm diameter parabolic radiometer antenna mounted near the bottom of the mast.

A conical superstructure mounted on top of the frame held the high-gain 1 meter diameter parabolic antenna and four solar panels, each measuring 215 x, were affixed to the top corners of the frame.

A microwave radiometer and an infrared radiometer and the radiometer reference horns were rigidly mounted to a 48 cm diameter parabolic radiometer antenna mounted near the bottom of the mast.

The beam divergence of an electromagnetic beam is an angular measure of the increase in beam diameter or radius with distance from the optical aperture or antenna aperture from which the electromagnetic beam emerges.

The angular resolution of a dish style antenna is determined by the diameter of the dish expressed as a number of wavelengths of the electromagnetic radiation being observed.

The largest single-dish radio telescope in Europe is the 100-meter diameter antenna in Effelsberg, Germany, which also was the world's largest fully steerable telescope for 30 years until the slightly larger Green Bank Telescope was opened in West Virginia, United States, in 2000.

This creates a combined telescope that is equivalent in resolution ( though not in sensitivity ) to a single antenna whose diameter is equal to the spacing of the antennas furthest apart in the array.

The diagram at the right shows the high-gain antenna ( HGA ) with a 3. 66 meter diameter attached to the hollow decagonal electronics container.

Communications were through a fixed 0. 45 m diameter high-gain antenna designed to support data rates greater than 100 kbit / s at encounters.

Communications were via a 10 W transmitter and the directional 1 m diameter high gain antenna for transmission of photographs and a 0. 5 W transmitter and omnidirectional low gain antenna for other communications.

The antenna uses a microwave lens 560 km in diameter, would transmit 56 GW of power, and would accelerate the probe to 10 % of the speed of light.

He submitted a proposal to Bell Labs to build a 30 meter diameter dish antenna with greater sensitivity that would allow more careful measurements of the structure and strength of the radio emission.

As Huygens was too small to transmit directly to Earth, it was designed to transmit the telemetry data obtained while descending through Titan's atmosphere to Cassini by radio, which would in turn relay it to Earth using its large 4-meter diameter main antenna.

It turns out that the amount of reactance seen at the terminals of a resonant antenna when the frequency is shifted, say, by 5 %, depends very much on the diameter of the conductor used.

in terms of terms of ratio of antenna length or diameter, to wavelength.

The reflector is a metallic surface formed into a paraboloid of revolution and usually truncated in a circular rim that forms the diameter of the antenna.
