The Very Large Array at Socorro, New Mexico, United States.Radio telescopes are directional radio antennas that often have a parabolic shape. The dishes are sometimes constructed of a conductive wire mesh whose openings are smaller than the wavelength being observed. Multi-element Radio telescopes are constructed from pairs or larger groups of these dishes to synthesize large 'virtual' apertures that are similar in size to the separation between the telescopes; this process is known as aperture synthesis. As of 2005, the current record array size is many times the width of the Earth—utilizing space-based Very Long Baseline Interferometry (VLBI) telescopes such as the Japanese HALCA (Highly Advanced Laboratory for Communications and Astronomy) VSOP (VLBI Space Observatory Program) satellite. Aperture synthesis is now also being applied to optical telescopes using optical interferometers (arrays of optical telescopes) and aperture masking interferometry at single reflecting telescopes. Radio telescopes are also used to collect microwave radiation, which is used to collect radiation when any visible light is obstructed or faint, such as from quasars. Some radio telescopes are used by programs such as SETI and the Arecibo Observatory to search for exterrestrial life.

Variations In Forklift Designs
Among one of the most popular forms of high-reaching equipment is the forklift. It sees usage in various aspects of heavy work, including construction, warehousing, and other forms of material handling. It is also employed in manufacturing industries. It is best used in conveying, lifting, and engaging heavy loads. Different forklifts have been designed to accommodate various tasks. Each one is specially manufactured to suit specific needs. As a user, identifying what these needs are is the first step to choosing the right unit.
A forklift may either run electrically or through internal combustion. Electric forklifts are better suited for indoor work. They are popular for their efficiency in heavy lifting and low operation costs. Internal combustion forklifts, on the other hand, are more effective for outdoor use. They are especially useful to operations that require quick action, which includes efficient re-fueling. Under these two major types of categories are even more sub-categories. A more generalized classification includes fork trucks, motorized, and manual drive. The first two types are motorized while the third engages the workload manually.
Even then, there are even more specially designed versions. For instance, there are forklifts that have been designed to work in narrow aisles, allowing for optimal stacking in limited space.
The attachments and variations on a forklift may range from being very simple to extremely specialized. Generally, a forklift is counterbalanced to prevent it from overturning. The presence and location of the counterweight depends on the task at hand. For instance, a stand-up narrow aisle rider, which is used in tight spaces, is built with straddle legs on either side to provide balance. Other types like stand-up or sit-down riders have actual counterweights built into the body of the unit. The counterweight for the latter is positioned at the rear of the machine. There are also forklifts that specialize in operations on rough terrain. The design variations on these forklifts include large tires and booms that serve to accommodate uneven surfaces.
Forklifts may also be classified based on the type of security they provide for the rider. A familiarity with the different designs and attachments on a forklift will help render the best results on the ground. For more information visit to our site at http://www.ahern.com
