Total Fertility Rate
The total fertility rate (TFR) of a population is the average number of children that would be born to a woman over her lifetime if: # she were to experience the exact current age-specific fertility rates (ASFRs) through her lifetime # she were to live from birth until the end of her reproductive life. It is obtained by summing the single-year age-specific rates at a given time. As of 2021, the total fertility rate varied from 0.81 in South Korea to 6.91 in Niger. Fertility tends to be correlated with the level of economic development. Historically, developed countries usually have a significantly lower fertility rate, generally correlated with greater wealth, education, urbanization, and other factors. Conversely, in undeveloped countries, fertility rates tend to be higher. Families desire children for their labor and as caregivers for their parents in old age. Fertility rates are also higher due to the lack of access to contraceptives, stricter adherence to traditional relig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transferrin Receptor
Transferrin receptor (TfR) is a carrier protein for transferrin. It is needed for the import of iron into the cell and is regulated in response to intracellular iron concentration. It imports iron by internalizing the transferrin-iron complex through receptor-mediated endocytosis.Figure 3: The cycle of transferrin and transferrin receptor 1-mediated cellular iron uptake./ref> The existence of a receptor for transferrin iron uptake had been recognized over half a century back. Earlier two transferrin receptors in humans, transferrin receptor 1 and transferrin receptor 2 had been characterized and until recently cellular iron uptake was believed to occur chiefly via these two well documented transferrin receptors. Both these receptors are transmembrane glycoproteins. TfR1 is a high affinity ubiquitously expressed receptor while expression of TfR2 is restricted to certain cell types and is unaffected by intracellular iron concentrations. TfR2 binds to transferrin with a 25-30 fold low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Texans For Fiscal Responsibility
Empower Texans was a conservative advocacy group in Texas that was active from 2006 to 2020. It was affiliated with Texans for Fiscal Responsibility and the Empower Texans Foundation. Empower Texans was based in Austin with operations in Dallas, Houston, and Midland. Empower Texans focused on fiscal conservatism by supporting lower taxes and spending restraint. It operated in Republican state-level politics in Texas, targeting candidates whom the group views as insufficiently conservative in Republican primaries. History Empower Texans was formed in 2006 by businessman Tim Dunn. Dunn was the group's primary financial contributor. Dan and Farris Wilks were also major donors to Empower Texans. The group was described as Tea Party-aligned. In 2014, Empower Texans CEO Michael Quinn Sullivan was fined by the Texas Ethics Commission after the agency alleged that he had failed to register as a lobbyist starting in 2010. Sullivan said his activities were best described as journalism rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thrift Financial Report
All regulated financial institutions in the United States are required to file periodic financial and other information with their respective regulators and other parties. Thrifts are required by the Office of Thrift Supervision (OTS), among other requirements, to file a key quarterly financial report called the Thrift Financial Report (TFR) to be filed electronically with the OTS. In 2007, there had been a proposal that thrifts convert to filing a similar report, the ''Report of Condition and Income'' commonly referred to as the Call Report, which banks prepare and file with the Federal Deposit Insurance Corporation. Since thrifts continue to file TFRs today, the proposal was dismissed or set aside for the time being. Specifically, OTS regulation 12 CFR 563.180 requires the completion of the TFR by all savings associations as defined in 12 CFR 561.43. The TFR is filed electronically on a quarterly basis and is due no later than 30 days after quarter end, except for Schedule HC ...

Temporary Flight Restriction
The Federal Aviation Regulations (FARs) are rules prescribed by the Federal Aviation Administration (FAA) governing all aviation activities in the United States. The FARs comprise Title 14 of the Code of Federal Regulations (CFR). A wide variety of activities are regulated, such as aircraft design and maintenance, typical airline flights, pilot training activities, hot-air ballooning, lighter-than-air aircraft, man-made structure heights, obstruction lighting and marking, model rocket launches, commercial space operations, model aircraft operations, Unmanned Aircraft Systems (UAS) and kite flying. The rules are designed to promote safe aviation, protecting pilots, flight attendants, passengers and the general public from unnecessary risk. FAR vs. 14 CFR Since 1958, these rules have typically been referred to as "FARs", short for Federal Aviation Regulations. However, another set of regulations (Title 48) is titled "Federal Acquisitions Regulations", and this has led to confu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terrain-following Radar
Terrain-following radar (TFR) is a military aerospace technology that allows a very-low-flying aircraft to automatically maintain a relatively constant altitude above ground level and therefore make detection by enemy radar more difficult. It is sometimes referred to as ''ground hugging'' or ''terrain hugging'' flight. The term ''nap-of-the-earth'' flight may also apply but is more commonly used in relation to low-flying military helicopters, which typically do not use terrain-following radar. TFR systems work by scanning a radar beam vertically in front of the aircraft and comparing the range and angle of the radar reflections to a pre-computed ideal manoeuvring curve. By comparing the distance between the terrain and the ideal curve, the system calculates a manoeuvre that will make the aircraft clear the terrain by a pre-selected distance, often on the order of . Using TFR allows an aircraft to automatically follow terrain at very low levels and high speeds. Terrain-following r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time–frequency Representation
A time–frequency representation (TFR) is a view of a signal (taken to be a function of time) represented over both time and frequency. Time–frequency analysis means analysis into the time–frequency domain provided by a TFR. This is achieved by using a formulation often called "Time–Frequency Distribution", abbreviated as TFD. TFRs are often complex-valued fields over time and frequency, where the modulus of the field represents either amplitude or "energy density" (the concentration of the root mean square over time and frequency), and the argument of the field represents phase. Background and motivation A signal, as a function of time, may be considered as a representation with perfect ''time resolution''. In contrast, the magnitude of the Fourier transform (FT) of the signal may be considered as a representation with perfect ''spectral resolution'' but with no time information because the magnitude of the FT conveys frequency content but it fails to convey when, in tim ...

Tokamak De Fontenay Aux Roses
The Tokamak de Fontenay-aux-Roses (TFR) was the first French tokamak, built in a research centre of the French Atomic Energy Commission (CEA) in Fontenay-aux-Roses, a commune in the southwestern suburbs of Paris, France. Roughly the same size as the contemporary Soviet T-3 and American Symmetrical Tokamak, but had a larger internal plasma volume and a much more powerful power supply that drove plasma currents up to 400,000 Amps for as long as half a second. Completed in 1973, it remained the world's most powerful tokamak until 1976 when it was surpassed by the Princeton Large Torus. Among the major discoveries made on TFR was the concept of "disruptions", potentially damaging events that eject the plasma from the center and lead to an event known as "runaway electrons". In 1975, such an event burned holes through the vacuum vessel, requiring extensive repairs. It was followed by Tore Supra WEST, Tungsten (chemical symbol "W") Environment in Steady-state Tokamak, (formerly Tore S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transnet Freight Rail
Transnet Freight Rail is a South African rail transport company, formerly known as Spoornet. It was part of the South African Railways and Harbours Administration, a state-controlled organisation that employed hundreds of thousands of people for decades from the first half of the 20th century and was widely referred to by the initials SAR&H (SAS&H in Afrikaans). Customer complaints about serious problems with Transnet Freight Rail's service were reported in 2010. Its head office is in Inyanda House in Parktown, Johannesburg. History Railways were first developed in the area surrounding Cape Town and later in Durban around the 1840s. The first line opened in Durban on 27 June 1850. The initial network was created to serve the agricultural production area between Cape Town and Wellington. The news that there were gold deposits in the Transvaal Republic moved the Cape Colony Government (supported by British Government) to link Kimberley as soon as possible by rail to Cape Town ...

Task Force Ranger
Operation Gothic Serpent was a military operation conducted in Mogadishu, Somalia, by an American force code-named ''Task Force Ranger'' during the Somali Civil War in 1993. The primary objective of the operation was to capture Mohamed Farrah Aidid, a Somalia clan leader who was wanted by the Unified Task Force in response to his attacks against United Nations troops. The operation took place from August to October 1993 and was led by US Joint Special Operations Command (JSOC). On 3 October 1993, the task force executed a mission to capture two of Aidid's lieutenants. The mission ultimately culminated in what became known as the 1993 Battle of Mogadishu. The battle was extremely bloody and the task force inflicted massive casualties on Somali militia forces, while suffering heavy losses themselves. The Malaysian, Pakistani, and conventional US Army troops under UNOSOM II which aided in TF Ranger's extraction suffered losses as well, though not as heavy. Overall, the Somali Na ...
