A steamroller (or steam roller) is a form of road roller – a type of heavy construction machinery used for levelling surfaces, such as roads or airfields – that is powered by a steam engine. The levelling/flattening action is achieved through a combination of the size and weight of the vehicle and the rolls: the smooth wheels and the large cylinder or drum fitted in place of treaded road wheels.

It is the earliest type of power shovel or excavator. They played a major role in public works in the 19th and early 20th century, being key to the construction of railroads and the Panama Canal. The development of simpler, cheaper diesel-powered shovels caused steam shovels to fall out of use in the 1930s.

Steppers are an essential part of the complex process, called photolithography, that creates millions of microscopic circuit elements on the surface of tiny chips of silicon. These chips form the heart of ICs such as computer processors, memory chips, and many other devices.

Stereotactic surgery or stereotaxy (not to be confused with the virtuality concept of stereotaxy) is a minimally invasive form of surgical intervention which makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS) etc.

The projection is defined on the entire sphere, except at one point: the projection point. Where it is defined, the mapping is smooth and bijective. It is conformal, meaning that it preserves angles. It is neither isometric nor area-preserving: that is, it preserves neither distances nor the areas of figures.

The Stillwater Bridge (alternatively known as the Stillwater Lift Bridge, St. Croix River Bridge at Stillwater, Mn/DOT Bridge #4654, and Wis/DOT Bridge #M-61) is a vertical lift bridge crossing the St. Croix River between Stillwater, Minnesota, and Houlton, Wisconsin. It connects Minnesota State Highway 36 and WIS 64, and is one of two bridges on the river between the Interstate 94 bridge in Hudson, Wisconsin and the U.S. Highway 8 bridge in Taylors Falls, Minnesota, providing a popular and useful alternative to those crossings. (The other bridge is the Minnesota State Highway 243 bridge, in Osceola, Wisconsin) Around 18,000 vehicles cross the bridge daily.
High Quality Content by WIKIPEDIA articles! The Stonehenge road tunnel was a controversial tunnel in Wiltshire, England proposed by the Highways Agency to upgrade the A303 road. It would have moved the A303 into a tunnel under the Stonehenge World Heritage Site and close the A344 road. The project was designed to improve the landscape around the monument and to improve safety on the primary A303 and was part of proposals to change the site in other ways including moving the visitors centre.
High Quality Content by WIKIPEDIA articles! The Stone Bridge is a causeway built by the United States Army in 1867. It crosses the marshy channel that connects Hart Lake and Crump Lake in a remote area of Lake County in eastern Oregon, United States. It was later incorporated into the Oregon Central Military Wagon Road which was completed in 1872. The wagon road eventually became the subject of scandal and litigation ending with a United States Supreme Court decision in 1893. The Stone Bridge and the Oregon Central Military Wagon Road were listed together on the National Register of Historic Places in 1974. Today, the Stone Bridge is located on land claimed by the State of Oregon under riparian rights. The wagon road adjacent to the...

The line extends from the Frankston line and is part of the city`s suburban passenger railway network, and is part of the Metlink integrated ticketing system (zone 2), but is not electrified like the rest of Melbourne`s rail network. The passenger service has been operated with a variety of rolling stock over the past few decades, and was the last suburban service in Australia to be operated by a locomotive hauled train, after the demise of similar services in Brisbane by Queensland Rail. The line is also used by freight trains serving a steel mill.
High Quality Content by WIKIPEDIA articles! In passing through matter, fast charged particles ionize the atoms or molecules which they encounter. Thus, the fast particles gradually lose energy in many small steps. Stopping power is defined as the average energy loss of the particle per unit path length, measured for example in MeV/cm (see figure to the right). Stopping power is a necessary ingredient for many parts of basic science, for medical and for technological applications.
