Teufen AR
Teufen is a municipality in the canton of Appenzell Ausserrhoden in Switzerland. History Teufen (''Tiuffen'') was first mentioned in 1272. By 1300 the place consisted of only five farms. In 1525 the assembly ruled that each parish could decide whether or not to remain Catholic. This led to the division of Appenzell in 1597. While the town of Teufen adopted the new protestant faith, Wonnenstein Friary remained Roman Catholic. In 1870 the Friary grounds were declared an exclave of Appenzell Innerrhoden. In 1841 Teufen offered their new school building as a present to attract the government of the canton. The assembly refused the present. Weaving was important in Teufen. Around 1820 a new loom was invented in Teufen, allowing embroidery in one go. This led to a boom in embroidery, particularly between 1880 and 1890. Geography , Teufen has an area of . Of this area, 55.4% is used for agricultural purposes, while 29.8% is forested. Of the rest of the land, 14% is settled (build ...

Loom
A loom is a device used to weaving, weave cloth and tapestry. The basic purpose of any loom is to hold the Warp (weaving), warp threads under tension (mechanics), tension to facilitate the interweaving of the weft threads. The precise shape of the loom and its mechanics may vary, but the basic function is the same. Etymology and usage The word "loom" derives from the Old English ''geloma'', formed from ''ge-'' (perfective prefix) and ''loma'', a root of unknown origin; the whole word ''geloma'' meant a utensil, tool, or machine of any kind. In 1404 "lome" was used to mean a machine to enable weaving thread into cloth. By 1838 "loom" had gained the additional meaning of a machine for interlacing thread.

Becquerel
The becquerel (; symbol: Bq) is the unit of radioactivity in the International System of Units (SI). One becquerel is defined as an activity of one per second, on average, for aperiodic activity events referred to a radionuclide. For applications relating to human health this is a small quantity, and SI multiples of the unit are commonly used. The becquerel is named after Henri Becquerel, who shared a Nobel Prize in Physics with Pierre and Marie Curie in 1903 for their work in discovering radioactivity. Definition 1 Bq = 1 s−1 A special name was introduced for the reciprocal second (s) to represent radioactivity to avoid potentially dangerous mistakes with prefixes. For example, 1 μs would mean 10 disintegrations per second: , whereas 1 μBq would mean 1 disintegration per 1 million seconds. Other names considered were hertz (Hz), a special name already in use for the reciprocal second (for ''periodic'' events of any kind), and fourier (Fr; after ...

Super-LumiNova
Super-LumiNova is a brand name under which strontium aluminate–based non-radioactive and nontoxic photoluminescent or afterglow pigments for illuminating markings on watch dials, hands and bezels, etc. in the dark are marketed. When activated with a suitable dopant (Europium and Dysprosium), it acts as a photoluminescent phosphor with long persistence of phosphorescence. This technology offers up to ten times higher brightness than previous zinc sulfide–based materials. These types of phosphorescent pigments, often called lume, operate like a rechargeable light battery. After sufficient activation by sunlight, fluorescent, LED, UV (blacklight), incandescent and other light sources, they glow in the dark for hours. Electrons within the pigment are being "excited" by ultraviolet light exposure—the excitation wavelengths for strontium aluminate range from 200 to 450 nm electromagnetic radiation—to a higher energetic state and after the excitation source is removed, ...

Tritium
Tritium () or hydrogen-3 (symbol T or H) is a rare and radioactive isotope of hydrogen with a half-life of ~12.33 years. The tritium nucleus (t, sometimes called a ''triton'') contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (''protium'') contains one proton and no neutrons, and that of non-radioactive hydrogen-2 ('' deuterium'') contains one proton and one neutron. Tritium is the heaviest particle-bound isotope of hydrogen. It is one of the few nuclides with a distinct name. The use of the name hydrogen-3, though more systematic, is much less common. Naturally occurring tritium is extremely rare on Earth. The atmosphere has only trace amounts, formed by the interaction of its gases with cosmic rays. It can be produced artificially by irradiation of lithium or lithium-bearing ceramic pebbles in a nuclear reactor and is a low-abundance byproduct in normal operations of nuclear reactors. Tritium is used as the energy source in radio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precipitation (meteorology)
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls from clouds due to gravitational pull. The main forms of precipitation include drizzle, rain, rain and snow mixed ("sleet" in Commonwealth usage), snow, ice pellets, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity), so that the water condenses and "precipitates" or falls. Thus, fog and mist are not precipitation; their water vapor does not condense sufficiently to precipitate, so fog and mist do not fall. (Such a non-precipitating combination is a colloid.) Two processes, possibly acting together, can lead to air becoming saturated with water vapor: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called shower (p ...

Tertiary Sector Of The Economy
The tertiary sector of the economy, generally known as the service sector, is the third of the three economic sectors in the three-sector model (also known as the economic cycle). The others are the primary sector (raw materials) and the secondary sector (manufacturing). The tertiary sector consists of the provision of Service (economics), services instead of Product (business), end products. Services (also known as "Intangible good, intangible goods") include attention, advice, access, experience and affective labour. The tertiary sector involves the provision of services to other businesses as well as to final consumers. Services may involve the transport, distribution (economics), distribution and sale of goods from a producer to a consumer, as may happen in wholesaler, wholesaling and retailer, retailing, pest control or financial services. The goods may be transformed in the process of providing the service, as happens in the restaurant industry. However, the focus is ...

Secondary Sector Of The Economy
In macroeconomics, the secondary sector of the economy is an economic sector in the three-sector theory that describes the role of manufacturing. It encompasses industries that produce a finished, usable product or are involved in construction. This sector generally takes the output of the primary sector (i.e. raw materials like metals, wood) and creates finished goods suitable for sale to domestic businesses or consumers and for export (via distribution through the tertiary sector). Many of these industries consume large quantities of energy, require factories and use machinery; they are often classified as light or heavy based on such quantities. This also produces waste materials and waste heat that may cause environmental problems or pollution (see negative externalities). Examples include textile production, car manufacturing, and handicraft. Manufacturing is an important activity in promoting economic growth and development. Nations that export manufactured p ...

Primary Sector Of The Economy
The primary sector of the economy includes any industry involved in the extraction and production of raw materials, such as farming, logging, fishing, forestry and mining. The primary sector tends to make up a larger portion of the economy in developing countries than it does in developed countries. For example, in 2018, agriculture, forestry, and fishing comprised more than 15% of GDP in sub-Saharan Africa but less than 1% of GDP in North America. In developed countries the primary sector has become more technologically advanced, enabling for example the mechanization of farming, as compared with lower-tech methods in poorer countries. More developed economies may invest additional capital in primary means of production: for example, in the United States corn belt, combine harvesters pick the corn, and sprayers spray large amounts of insecticides, herbicides and fungicide Fungicides are pesticides used to kill parasitic fungi or their spores. Fungi can cause serious d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fachhochschule
A (; plural ), abbreviated FH, is a university of applied sciences (UAS), in other words a Hochschule, German tertiary education institution that provides professional education in many applied sciences and applied arts, such as engineering, technology, business, architecture, design, and industrial design. were first founded in Germany and were later adopted in Austria, Liechtenstein, Switzerland, Cyprus, and Greece. An increasing number of are abbreviated as ''Hochschule'', the generic term in Germany for institutions awarding academic degrees in higher education, or expanded as ''Hochschule für angewandte Wissenschaften (HAW)'', the German translation of "universities of applied sciences", which were primarily designed with a focus on teaching professional skills. This is reflected in the fact that the ratio of the number of students to the number of professors is significantly better than at traditional universities. However, there are also a number of subjects, such as s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Education In Switzerland
The education system in Switzerland is very diverse, because the constitution of Switzerland delegates the authority for the school system mainly to the Canton of Switzerland, cantons. The Swiss constitution sets the foundations, namely that primary school is obligatory for every child and is free in state schools and that the confederation can run or support universities. The minimum age for primary school is about six years in all cantons but Obwalden, where it is five years and three months. After primary schools, the pupils split up according to their abilities and intentions of career paths. Roughly 25% of all students attend lower and upper secondary schools leading, normally after 12 school years in total to the federal recognized matura or an academic International Baccalaureate, Baccalaureate which grants access to all universities. The other students split in two or more school-types, depending on the canton, differing in the balance between theoretical and practical e ...
