Thuringian Holzland
The Thuringian Holzland (german: Thüringer Holzland) is an upland region in the state of Thuringia, Germany. Location The Thuringian Holzland lies within a triangle formed by the towns of Hermsdorf, Eisenberg and Stadtroda and between the rivers Saale, White Elster and Orlasenke. Originally it comprised the following 8 villages: Bad Klosterlausnitz, Hermsdorf, Oberndorf, Reichenbach, Schleifreisen, Sankt Gangloff, Tautenhain and Weißenborn. Description and history The reason for the extensive forests of this landscape is its rather infertile soils, which have been formed from the sandstones of the Bunter formation that make up the area. As a result, the Holzland is of limited use for agriculture. The rich timber industry of the area meant that once typical occupations, such as ladder maker (''Leitermacher''), blacksmith (''Peckschmied''), tubmaker (''Muldenhauer''), etc., were very common here. Which is why the area is also often referred to not infrequently as ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thuringia
Thuringia (; german: Thüringen ), officially the Free State of Thuringia ( ), is a state of central Germany, covering , the sixth smallest of the sixteen German states. It has a population of about 2.1 million. Erfurt is the capital and largest city. Other cities are Jena, Gera and Weimar. Thuringia is bordered by Bavaria, Hesse, Lower Saxony, Saxony-Anhalt, and Saxony. It has been known as "the green heart of Germany" () from the late 19th century due to its broad, dense forest. Most of Thuringia is in the Saale drainage basin, a left-bank tributary of the Elbe. Thuringia is home to the Rennsteig, Germany's best-known hiking trail. Its winter resort of Oberhof makes it a well-equipped winter sports destination – half of Germany's 136 Winter Olympic gold medals had been won by Thuringian athletes as of 2014. Thuringia was favoured by or was the birthplace of three key intellectuals and leaders in the arts: Johann Sebastian Bach, Johann Wolfgang von Goet ...

Bunter Sandstone
The Buntsandstein (German for ''coloured'' or ''colourful sandstone'') or Bunter sandstone is a lithostratigraphic and allostratigraphic unit (a sequence of rock strata) in the subsurface of large parts of west and central Europe. The Buntsandstein predominantly consists of sandstone layers of the Lower Triassic series and is one of three characteristic Triassic units, together with the Muschelkalk and Keuper that form the Germanic Trias Supergroup. The Buntsandstein is similar in age, facies and lithology with the Bunter of the British Isles. It is normally lying on top of the Permian Zechstein and below the Muschelkalk. In the past the name Buntsandstein was in Europe also used in a chronostratigraphic sense, as a subdivision of the Triassic system. Among reasons to abandon this use was the discovery that its base lies actually in the latest Permian. Origin The Buntsandstein was deposited in the Germanic Basin, a large sedimentary basin that was the successor of the smal ...

Holzland Railway
Holzland is the name of a region in the western part of the Palatine Forest in the German state of Rhineland-Palatinate Location and structure The Holzland is clearly bounded by surrounding streams: to the south and southeast by the Schwarzbach (Blies), Schwarzbach, and, to the west and north by its tributary, the Moosalb (Palatine Forest), Moosalb. Only in the extreme east, by the Steinberg, does the Holzland transition without any clearly defined features into the Frankenweide. The valleys that border and cut through the Holzland are, in places, largely natural. Many, mighty sandstone rock formations outcrop on the valley sides. Hillsides and heights are covered by valuable mixed forest, except in the immediate vicinity of villages. The old sessile oaks harvested here, which are often several centuries old, earn the highest lumber prices overall. History The quality and density of its stands of trees gives the Holzland ("wood land") its name. Even during times when large a ...

Gera
Gera is a city in the German state of Thuringia. With around 93,000 inhabitants, it is the third-largest city in Thuringia after Erfurt and Jena as well as the easternmost city of the ''Thüringer Städtekette'', an almost straight string of cities consisting of the six largest Thuringian cities from Eisenach in the west, via Gotha, Erfurt, Weimar and Jena to Gera in the east. Gera is the largest city in the Vogtland, and one of its historical capitals along with Plauen, Greiz and Weida. The city lies in the East Thuringian Hill Country, in the wide valley of the White Elster, between Greiz (upstream) and Leipzig (downstream). Gera is located in the Central German Metropolitan Region, approximately south of Saxony's largest city of Leipzig, east of Thuringia's capital Erfurt, west of Saxony's capital Dresden and 90 km (56 miles) north of Bavaria's city of Hof (Saale). First mentioned in 995 and developing into a city during the 13th century, Gera has historical sig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jena
Jena () is a German city and the second largest city in Thuringia. Together with the nearby cities of Erfurt and Weimar, it forms the central metropolitan area of Thuringia with approximately 500,000 inhabitants, while the city itself has a population of about 110,000. Jena is a centre of education and research; the Friedrich Schiller University was founded in 1558 and had 18,000 students in 2017 and the Ernst-Abbe-Fachhochschule Jena counts another 5,000 students. Furthermore, there are many institutes of the leading German research societies. Jena was first mentioned in 1182 and stayed a small town until the 19th century, when industry developed. For most of the 20th century, Jena was a world centre of the optical industry around companies such as Carl Zeiss, Schott and Jenoptik (since 1990). As one of only a few medium-sized cities in Germany, it has some high-rise buildings in the city centre, such as the JenTower. These also have their origin in the former Carl Zeiss fa ...

Weimar
Weimar is a city in the state of Thuringia, Germany. It is located in Central Germany between Erfurt in the west and Jena in the east, approximately southwest of Leipzig, north of Nuremberg and west of Dresden. Together with the neighbouring cities of Erfurt and Jena, it forms the central metropolitan area of Thuringia, with approximately 500,000 inhabitants. The city itself has a population of 65,000. Weimar is well known because of its large cultural heritage and its importance in German history. The city was a focal point of the German Enlightenment and home of the leading figures of the literary genre of Weimar Classicism, writers Johann Wolfgang von Goethe and Friedrich Schiller. In the 19th century, noted composers such as Franz Liszt made Weimar a music centre. Later, artists and architects such as Henry van de Velde, Wassily Kandinsky, Paul Klee, Lyonel Feininger, and Walter Gropius came to the city and founded the Bauhaus movement, the most important German de ...

Restaurant
A restaurant is a business that prepares and serves food and drinks to customers. Meals are generally served and eaten on the premises, but many restaurants also offer take-out and food delivery services. Restaurants vary greatly in appearance and offerings, including a wide variety of cuisines and service models ranging from inexpensive fast-food restaurants and cafeterias to mid-priced family restaurants, to high-priced luxury establishments. Etymology The word derives from early 19th century from French word 'provide food for', literally 'restore to a former state' and, being the present participle of the verb, The term ''restaurant'' may have been used in 1507 as a "restorative beverage", and in correspondence in 1521 to mean 'that which restores the strength, a fortifying food or remedy'. History A public eating establishment similar to a restaurant is mentioned in a 512 BC record from Ancient Egypt. It served only one dish, a plate of cereal, wild fowl, and on ...

Service Industries
Service industries are those not directly concerned with the production of physical goods (such as agriculture and manufacturing). Some service industries, including transportation, wholesale trade and retail trade are part of the supply chain delivering goods produced in the agricultural and manufacturing sectors to final consumers. Other services are provided directly to consumers. These include health care, education, information services, legal services, financial services, and public administration. The service sector accounts for around 70-80 per cent of employment in modern economies. Service industries in the three-sector model In the three-sector model of the economy, widely used in the 20th century, the service sector was assigned the role of transporting, distributing and selling goods produced in the manufacturing (secondary sector), and was therefore described as the tertiary sector of the economy. However, the majority of service employment is now found in activi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powder Metallurgy
Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders. PM processes can reduce or eliminate the need for subtractive processes in manufacturing, lowering material losses and reducing the cost of the final product. Powder metallurgy is also used to make unique materials impossible to get from melting or forming in other ways. A very important product of this type is tungsten carbide (WC). WC is used to cut and form other metals and is made from WC particles bonded with cobalt. It is very widely used in industry for tools of many types and globally ~50,000 tonnes/year (t/y) is made by PM. Other products include sintered filters, porous oil-impregnated bearings, electrical contacts and diamond tools. Since the advent of industrial production–scale metal powder–based additive manufacturing (AM) in the 2010s, selective laser sintering and other metal AM processes are a new category of commercially important ...

Micromachinery
Micromachines are mechanical objects that are fabricated in the same general manner as integrated circuits. They are generally considered to be between 100 nanometres to 100 micrometres in size, though that is debatable. The applications of micromachines include accelerometers that detect when a car has hit an object and trigger an airbag. Complex systems of gears and levers are another application. Fabrication The fabrication of these devices is usually done by two techniques, surface micromachining and bulk micromachining. To do bulk micromachining, the region needed is highly doped with boron and the unwanted silicon is etched in liquid silicon etches. This technique is termed an etchstop as the doping of boron produces an unetchable layer/pattern. Transducers Most micromachines act as transducers; in other words, they are either sensors or actuators. Sensors convert information from the environment into interpretable electrical signals. One example of a micromachine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micro-electronics
Microelectronics is a subfield of electronics. As the name suggests, microelectronics relates to the study and manufacture (or microfabrication) of very small electronic designs and components. Usually, but not always, this means micrometre-scale or smaller. These devices are typically made from semiconductor materials. Many components of normal electronic design are available in a microelectronic equivalent. These include transistors, capacitors, inductors, resistors, diodes and (naturally) insulators and conductors can all be found in microelectronic devices. Unique wiring techniques such as wire bonding are also often used in microelectronics because of the unusually small size of the components, leads and pads. This technique requires specialized equipment and is expensive. Digital integrated circuits (ICs) consist of billions of transistors, resistors, diodes, and capacitors. Analog circuits commonly contain resistors and capacitors as well. Inductors are used in som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
