Khirsadoh Junction is a small railway junction near Chhindwara city in Madhya Pradesh, India.
The M25 or London Orbital Motorway is a major road encircling most of Greater London. The 117-mile (188-kilometre) motorway is one of the most important roads in the UK and one of the busiest. Margaret Thatcher opened the final section in 1986, making the M25 the longest ring road in Europe upon opening. The Dartford Crossing completes the orbital route but is not classed as motorway; it is classed as a trunk road and designated as the A282. In some cases, including notable legal contexts such as the Communications Act 2003, the M25 is used as a de facto alternative boundary for Greater London.
A transistor is a semiconductor device used to amplify or switch electrical signals and power. It is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more in miniature form are found embedded in integrated circuits. Because transistors are the key active components in practically all modern electronics, many people consider them one of the 20th century's greatest inventions.
A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor (FET), uses only one kind of charge carrier. A bipolar transistor allows a small current injected at one of its terminals to control a much larger current flowing between the terminals, making the device capable of amplification or switching.
Grand Junction is a home rule municipality that is the seat of government and largest city of Mesa County, Colorado, United States. Grand Junction's population was 65,560 at the 2020 United States Census, making it the most populous city in western Colorado and the 17th most populous Colorado municipality overall.
An intersection or an at-grade junction is a junction where two or more roads converge, diverge, meet or cross at the same height, as opposed to an interchange, which uses bridges or tunnels to separate different roads. Major intersections are often delineated by gores and may be classified by road segments, traffic controls and lane design.
The M1 motorway connects London to Leeds, where it joins the A1(M) near Aberford, to connect to Newcastle. It was the first inter-urban motorway to be completed in the UK; the first motorway in the country was the Preston Bypass, which later became part of the M6.
The M4, originally the London-South Wales Motorway, is a motorway in the United Kingdom running from west London to southwest Wales. The English section to the Severn Bridge was constructed between 1961 and 1971; the Welsh element was largely complete by 1980, though a non-motorway section around Briton Ferry bridge remained until 1993. On the opening of the Second Severn Crossing in 1996, the M4 was rerouted over it.
Clapham Junction railway station is a major railway station and transport hub near St John's Hill in south-west Battersea in the London Borough of Wandsworth. It is 2 miles 57 chains from London Victoria and 3 miles 74 chains from London Waterloo; it is on both the South West Main Line and Brighton Main Line as well as numerous other routes and branch lines passing through or diverging from the main lines at this station. Despite its name, Clapham Junction is not located in Clapham, a district situated approximately 1 mile (1.6 km) to the south-east and is instead sited in Battersea.
The M62 is a 107-mile-long (172 km) west–east trans-Pennine motorway in Northern England, connecting Liverpool and Hull via Manchester, Bradford, Leeds and Wakefield; 7 miles (11 km) of the route is shared with the M60 orbital motorway around Manchester. The road is part of the unsigned Euroroutes E20 and E22.
Gap junctions are one of four broad categories of intercellular connections that form between a multitude of animal cell types. First photographed around 1952, it wasn't until 1969 that gap junctions were referred to as "gap junctions". Named after the 2-4 nm gap they bridged between cell membranes, they had been characterised in more detail by 1967.
The M5 is a motorway in England linking the Midlands with the South West. It runs from junction 8 of the M6 at West Bromwich near Birmingham to Exeter in Devon. Heading south-west, the M5 runs east of West Bromwich and west of Birmingham through Sandwell Valley. It continues past Bromsgrove, Droitwich Spa, Worcester, Tewkesbury, Cheltenham, Gloucester, Bristol, Clevedon, Weston-super-Mare, Bridgwater, Taunton, terminating at junction 31 for Exeter. Congestion on the section south of the M4 is common during the summer holidays, on Friday afternoons and bank holidays.
A p–n junction is a boundary or interface between two types of semiconductor materials, p-type and n-type, inside a single crystal of semiconductor. The "p" (positive) side contains an excess of holes, while the "n" (negative) side contains an excess of electrons in the outer shells of the electrically neutral atoms there. This allows electric current to pass through the junction only in one direction. The p- and n-type regions creating the junction are made by doping the semiconductor, for example by ion implantation, diffusion of dopants, or by epitaxy.
A junction, in the context of rail transport, is a place at which two or more rail routes converge or diverge. This implies a physical connection between the tracks of the two routes, provided by points and signalling. Junctions are important for rail systems, their installation into a rail system can expand route capacity, and have a powerful impact upon on-time performance.
The Western Railway is one of the 19 zones of Indian Railways and is among the busiest railway networks in India, headquartered at Mumbai, Maharashtra. The major railway routes of Indian Railways which come under Western Railways are: Mumbai Central–Ratlam, Mumbai Central–Ahmedabad and Palanpur–Ahmedabad. The railway system is divided into six operating divisions: Ahmedabad, Vadodara, Rajkot, Bhavnagar, Ratlam, and Mumbai WR. Vadodara railway station, being the junction point for the Ahmedabad–Mumbai route and the Mumbai–Ratlam route towards New Delhi, is the busiest junction station in Western Railways and one of the busiest junctions of Indian Railways too, while Ahmedabad Division earns highest revenue followed by Mumbai Division and Vadodara Division. Surat railway station is one of the busiest railway station in Western Railway in non-junction category where more than 180 trains pass per day.
In civil engineering, grade separation is a method of aligning a junction of two or more surface transport axes at different heights (grades) so that they will not disrupt the traffic flow on other transit routes when they cross each other. The composition of such transport axes does not have to be uniform; it can consist of a mixture of roads, footpaths, railways, canals, or airport runways. Bridges, tunnels, or a combination of both can be built at a junction to achieve the needed grade separation.
New Jalpaiguri Junction railway station established in 1960, is an A1 category broad gauge and narrow-gauge railway station under Katihar railway division of Northeast Frontier Railway zone. It is the largest as well as the busiest railway junction of Northeast India. This junction is largest among the railway stations which serves the city of Siliguri, the largest metropolis of the North Bengal. The other stations are- Siliguri Junction, Gulma, Bagdogra, Matigara, Rangapani and Siliguri Town.
