Trimley Railway Station
Trimley railway station is on the Felixstowe Branch Line in the east of England, serving the village of Trimley St. Mary, Suffolk. It is down the line from and measured from London Liverpool Street; it is situated between and . Its three-letter station code is TRM. It was opened by the Great Eastern Railway (GER) in 1891 and built to a design by the company's chief architect, W. N. Ashbee; it was one of only two stations outside Essex to be built in the ''New Essex'', or ''Ashbee'', style. A branch line for goods trains to the port of Felixstowe was opened at Trimley in 1987. Today it is managed by Greater Anglia, which also operates all passenger trains that call. History The Felixstowe Railway and Pier Company opened their line from to 1 May 1877 but the nearest station, other than at the pier near Landguard Common, was '' at Nacton; a station at was soon added but this was on the far side of the town so of little use to people in the Trimleys. On 1 May 1891 that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Troy Transit Center
The Troy Transit Center is an unstaffed train station in Troy, Michigan, United States, that is served by Amtrak's ''Wolverine'', which runs thrice daily between Chicago, Illinois, and Pontiac, Michigan (via Kalamazoo, Ann Arbor, and Detroit, Michigan). It is also served by Suburban Mobility Authority for Regional Transportation (SMART). The transit center replaced the nearby Birmingham Amtrak station in October 2014. Description The transit center is located in the southwest corner of Troy at 1201 Doyle Drive. It is about southwest of the former Birmingham Station and is situated behind the Midtown Square shopping center. The Oakland/Troy Airport is located just a few blocks away, on the east side of Coolidge Highway. The transit center has fairly easy access from both I-75 and Woodward Avenue ( M-1). The Troy Transit Center brings together the services of Amtrak, SMART buses and taxis. Designed by local architectural firm Neumann/Smith, the one story, brick building inc ...

Thermoremanent Magnetization
When an igneous rock cools, it acquires a thermoremanent magnetization (TRM) from the Earth's field. TRM can be much larger than it would be if exposed to the same field at room temperature (see isothermal remanence). This remanence can also be very stable, lasting without significant change for millions of years. TRM is the main reason that paleomagnetists are able to deduce the direction and magnitude of the ancient Earth's field. History As early as the eleventh century, the Chinese were aware that a piece of iron could be magnetized by heating it until it was red hot, then quenching in water. While quenching it was oriented in the Earth's field to get the desired polarity. In 1600, William Gilbert published ''De Magnete'' (1600), a report of a series of meticulous experiments in magnetism. In it, he described the quenching of a steel rod in the direction of the Earth's field, and he may have been aware of the Chinese work. In the early 20th century, a few investigators foun ...

Time Reversal Mirror
Time Reversal Signal Processing has three main uses: creating an optimal carrier signal for communication, reconstructing a source event, and focusing high-energy waves to a point in space. A Time Reversal Mirror (TRM) is a device that can focus waves using the time reversal method. TRMs are also known as time reversal mirror arrays since they are usually arrays of transducers. TRM are well-known and have been used for decades in the optical domain. They are also used in the ultrasonic domain. Overview If the source is passive, i.e. some type of isolated reflector, an iterative technique can be used to focus energy on it. The TRM transmits a plane wave which travels toward the target and is reflected off it. The reflected wave returns to the TRM, where it looks as if the target has emitted a (weak) signal. The TRM reverses and retransmits the signal as usual, and a more focused wave travels toward the target. As the process is repeated, the waves become more and more focused ...

Tissue-resident Memory T Cell
Tissue-resident memory T cells or TRM cells represent a subset of a long-lived memory T cells that occupies epithelial and mucosal tissues (skin, mucosa, lung, brain, pancreas, gastrointestinal tract) without recirculating. TRM cells are transcriptionally, phenotypically and functionally distinct from central memory (TCM) and effector memory (TEM) T cells which recirculate between blood, the T cell zones of Lymphatic system, secondary lymphoid organ, lymph and nonlymphoid tissues. Moreover, TRM cells themself represent a diverse populations because of the specializations for the resident tissues. The main role of TRM cells is to provide superior protection against infection in extralymphoid tissues. Phenotype The main cell surface markers that has been associated with TRM are CD69 and ITGAE, CD103. CD69 suppress response to the S1P chemoattractant from blood and lymph and prevents TRM cells exit from peripheral tissue. Therefore, CD69 has a key role in distinguishing T cells in tis ...
