The Original Factory Shop
The Original Factory Shop is a discount department store chain that was established in 1969. It currently operates over two hundred stores across the United Kingdom. History The Original Factory Shop was established in 1969 as part of Peter Black's retail network. Initially it sold soap manufactured by one of Black's factories. The chain now has 215 outlets and has plans to have 500 stores by 2020. During 2010 to 2011, the chain expanded its warehouse and offices in Burnley by to provide for the future needs of the business. In August 2011, the chain did not perform as well with profits reduced, due to economic conditions and massive investment in the chain, including many store openings, expansion of headquarters and warehouse and upgrading store equipment. The chief executive of The Original Factory Shop is former Lloyds Pharmacy boss Tony Page, who replaced Angela Spindler in June 2013. In May 2010, rumours surfaced that the parent company Duke Street Capital put the chain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time Of Flight
Time of flight (ToF) is the measurement of the time taken by an object, particle or wave (be it acoustic, electromagnetic, etc.) to travel a distance through a medium. This information can then be used to measure velocity or path length, or as a way to learn about the particle or medium's properties (such as composition or flow rate). The traveling object may be detected directly (direct time of flight, dToF, e.g., via an ion detector in mass spectrometry) or indirectly (indirect time of flight, iToF, e.g., by light scattered from an object in laser doppler velocimetry). Overview In electronics, one of the earliest devices using the principle are ultrasonic distance-measuring devices, which emit an ultrasonic pulse and are able to measure the distance to a solid object based on the time taken for the wave to bounce back to the emitter. The ToF method is also used to estimate the electron mobility. Originally, it was designed for measurement of low-conductive thin films, later adju ...

Time-of-flight Camera
A time-of-flight camera (ToF camera), also known as time-of-flight sensor (ToF sensor), is a range imaging camera system for measuring distances between the camera and the subject for each point of the image based on time-of-flight, the round trip time of an artificial light signal, as provided by a laser or an LED. Laser-based time-of-flight cameras are part of a broader class of scannerless LIDAR, in which the entire scene is captured with each laser pulse, as opposed to point-by-point with a laser beam such as in scanning LIDAR systems. Time-of-flight camera products for civil applications began to emerge around 2000, as the semiconductor processes allowed the production of components fast enough for such devices. The systems cover ranges of a few centimeters up to several kilometers. Types of devices Several different technologies for time-of-flight cameras have been developed. RF-modulated light sources with phase detectors Photonic Mixer Devices (PMD), the Swiss Ranger, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time-of-flight Mass Spectrometry
Time-of-flight mass spectrometry (TOFMS) is a method of mass spectrometry in which an ion's mass-to-charge ratio is determined by a time of flight measurement. Ions are accelerated by an electric field of known strength. This acceleration results in an ion having the same kinetic energy as any other ion that has the same charge. The velocity of the ion depends on the mass-to-charge ratio (heavier ions of the same charge reach lower speeds, although ions with higher charge will also increase in velocity). The time that it subsequently takes for the ion to reach a detector at a known distance is measured. This time will depend on the velocity of the ion, and therefore is a measure of its mass-to-charge ratio. From this ratio and known experimental parameters, one can identify the ion. Theory The potential energy of a charged particle in an electric field is related to the charge of the particle and to the strength of the electric field: where ''E''p is potential energy, ''q'' ...

Tetralogy Of Fallot
Tetralogy of Fallot (TOF), formerly known as Steno-Fallot tetralogy, is a congenital heart defect characterized by four specific cardiac defects. Classically, the four defects are: *pulmonary stenosis, which is narrowing of the exit from the right ventricle; * a ventricular septal defect, which is a hole allowing blood to flow between the two ventricles; * right ventricular hypertrophy, which is thickening of the right ventricular muscle; and * an overriding aorta, which is where the aorta expands to allow blood from both ventricles to enter. At birth, children may be asymptomatic or present with many severe symptoms. Later in infancy, there are typically episodes of bluish colour to the skin due to a lack of sufficient oxygenation, known as cyanosis. When affected babies cry or have a bowel movement, they may undergo a "tet spell" where they turn cyanotic, have difficulty breathing, become limp, and occasionally lose consciousness. Other symptoms may include a heart murmur, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tracheoesophageal Fistula
A tracheoesophageal fistula (TEF, or TOF; see spelling differences) is an abnormal connection (fistula) between the esophagus and the trachea. TEF is a common congenital abnormality, but when occurring late in life is usually the sequela of surgical procedures such as a laryngectomy. Presentation Tracheoesophageal fistula is suggested in a newborn by copious salivation associated with choking, coughing, vomiting, and cyanosis coincident with the onset of feeding. Esophageal atresia and the subsequent inability to swallow typically cause polyhydramnios in utero. Rarely it may present in an adult. Complications Surgical repair can sometimes result in complications, including: * Stricture, due to gastric acid erosion of the shortened esophagus * Leak of contents at the point of anastomosis * Recurrence of fistula * Gastro-esophageal reflux disease * Dysphagia * Asthma-like symptoms, such as persistent coughing/wheezing * Recurrent chest infections * Tracheomalacia Associations ...

Turnover Frequency
Turnover number has two different meanings: In enzymology, turnover number (also termed ''k''cat) is defined as the maximum number of chemical conversions of substrate molecules per second that a single active site will execute for a given enzyme concentration _T/math> for enzymes with two or more active sites. For enzymes with a single active site, ''k''cat is referred to as the catalytic constant. It can be calculated from the maximum reaction rate V_\max and catalyst site concentration _T/math> as follows: :k_\mathrm = \frac (See Michaelis–Menten kinetics). In other chemical fields, such as organometallic catalysis, turnover number (abbreviated ''TON'') has a different meaning: the number of moles of substrate that a mole of catalyst can convert before becoming inactivated. An ideal catalyst would have an infinite turnover number in this sense, because it would never be consumed. The term turnover frequency (abbreviated ''TOF'') is used to refer to the turnover per unit tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogashevo Airport
Tomsk Bogashevo Airport (russian: Аэропорт Богашёво) is an airport that serves Tomsk, Russia. It is located approximately 20 km south-east of Tomsk city center, near the village Bogashevo in Tomsky District of Tomsk Oblast. History The airport opened in November 1967 and replaced another airport within the Kashtak district in the city of Tomsk. The Kashtak site was rebuilt with multistory apartment buildings and turned into a bedroom community of Tomsk. In 2004 and 2005, the passenger terminal and the open space in front of the airport were reconstructed at a cost of 70 million roubles. Construction of a new runway and facilities for flights to Central Asia began in 2006. The construction budget for 2006 totaled 120 million roubles. In fall 2006, construction began on a new road connecting Bogashevo to the Akademgorodok scientific research district. In 2020, Russian politician and government critic Alexey Navalny fell ill after drinking tea in the airp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tofalar
The Tofalar (Тофалары, тофа (tofa) in Russian; formerly known as карагасы or Karagas) or Tofa people, are a Turkic people in the Irkutsk Oblast in Russia. Their ethnonym contains the Turkic plural suffix -lar, thus it means "Tofas". Their origins, Tofa language and culture are close to those of the eastern Tuvans-Todzhins. Before the 1917 October Revolution, the Tofalar used to be engaged in nomadic, living in the taiga; they engaged in reindeer husbandry and hunting. The Tofalar were resettled by the Soviet government by 1932. Young Tofas learned Russian at new Soviet-built schools, while cultural traditions such as hunting and shamanism were discouraged or prohibited. According to the 2010 census, there were 762 Tofas in Russia (2,828 in 1926, 476 in 1959, 570 in 1970, 576 in 1979, 722 in 1989 and 837 in 2002). History Tofa people originated from the intermingling of various clans of Turkic, Mongolic, Yeniseian and Samoyedic origins. The original home of ...
