Berwyn station (CTA)

Berwyn is an 'L' station on the CTA's Red Line. It is located at 1121 West Berwyn Avenue in the Edgewater neighborhood of Chicago, Illinois. The adjacent stations are Bryn Mawr, located about ³⁄₈ mile (0.60 km) to the north, and Argyle, about ¹⁄₃ mile (0.54 km) to the south. Four tracks pass through the station, but there is only single island platform in the center of the tracks; Purple Line weekday rush hour express service uses the outside tracks but does not stop at this station. Berwyn is named for the Berwyn station in the community of the same name, which is west of Philadelphia. Many of the roads (and thus CTA stations) in the Edgewater neighborhood are named after stations on the former PRR Main Line.

History

The Northwestern Elevated Railroad extended its services north from Wilson to Central Street in Evanston in 1908, but they did not build a station at Berwyn Avenue until the tracks between Wilson and Howard were elevated onto an embankment between 1914 and 1922. This new station was built to a design by architect Charles P. Rawson; the date of opening is not known, but a station may have existed at Berwyn by 1917. At the time of its opening the station was named Edgewater Beach Station; the name was changed to Berwyn in the late 1950s, around about the time that Lake Shore Drive was extended from Foster Avenue to Hollywood Avenue destroying the namesake Edgewater beach.

Berwyn (SEPTA station)

Berwyn is a commuter rail station located in the western suburbs of Philadelphia at Cassatt Avenue and Lancaster Pike, Berwyn, Pennsylvania. It is served by most Paoli/Thorndale Line trains.

The station was built in 1884 by the Pennsylvania Railroad, and currently houses The Frame Station Gallery, "a full service gallery and framing design center." The station, platforms, and canopy were recently restored. A bridge over the tracks that formerly carried cars on Cassatt Avenue was converted into a pedestrian-only bridge.

The ticket office at this station is open weekdays from 5:45 a.m. to 1:10 p.m. excluding holidays. There are 140 parking spaces including SEPTA permit parking at the station.

This station is wheelchair-accessible with short lengths of high-level platforms on both sides of the tracks. The platforms have bridge plates which allow a wheelchair to cross the gap between the platform and the train when it is stopped at the platform.

This station is 17.5 track miles from Philadelphia's Suburban Station. In 2011, the average total weekday boardings at this station was 261, and the average total weekday alightings was 223.

Berwyn station (Metra)

Berwyn is one of three stations on Metra's BNSF Railway Line in Berwyn, Illinois. The station is 9.6 miles (15.4 km) from Union Station, the east end of the line. In Metra's zone-based fare system, Berwyn is in zone B. There is a staffed station building on the south side of the tracks.

Originally known as Burlington Suburban Station and built in 1890 for the Chicago, Burlington and Quincy Railroad line. It was formally determined to be eligible to be listed on the National Register of Historic Places in 1982, but, apparently because of the objections of the CB&Q, it was not listed.

Tantalum carbide

Tantalum carbides form a family of binary chemical compounds of tantalum and carbon with the empirical formula TaC_x, where x usually varies between 0.4 and 1. They are extremely hard, brittle, refractory ceramic materials with metallic electrical conductivity. They appear as brown-gray powders which are usually processed by sintering. Being important cermet materials, tantalum carbides are commercially used in tool bits for cutting applications and are sometimes added to tungsten carbide alloys. The melting points of tantalum carbides peak at about 3880 °C depending on the purity and measurement conditions; this value is among the highest for binary compounds. Only tantalum hafnium carbide may have a slightly higher melting point of about 3942 °C, whereas the melting point of hafnium carbide is comparable to that of TaC.

Preparation

TaC_x powders of desired composition are prepared by heating a mixture of tantalum and graphite powders in vacuum or inert gas atmosphere (argon). The heating is performed at temperature of about 2000 °C using a furnace or an arc-melting setup. An alternative technique is reduction of tantalum pentoxide by carbon in vacuum or hydrogen gas atmosphere at a temperature of 1500–1700 °C. This method was used to obtain tantalum carbide back in 1876, but it lacks control over the stoichiometry of the product.

CTA-102

In astronomy, CTA 102, also known by its B1950 coordinates as 2230+114 (QSR B2230+114) and its J2000 coordinates as J2232+1143 (QSO J2232+1143), is a quasar discovered in the early 1960s by a radio survey carried out by the California Institute of Technology. It has been observed by a large range of instruments since its discovery, including WMAP, EGRET, GALEX, VSOP and Parkes, and has been regularly imaged by the Very Long Baseline Array since 1995. It has also been detected in gamma rays, and a gamma-ray flare has been detected from it.

In 1963 Nikolai Kardashev proposed that the then-unidentified radio source could be evidence of a Type II or III extraterrestrial civilization on the Kardashev scale. Follow-up observations were announced in 1965 by Gennady Sholomitskii, who found that the object's radio emission was varying; a public announcement of these results caused a worldwide sensation. The idea that the emission was caused by a civilization was rejected when the radio source was later identified as one of the many varieties of a quasar.
