Stångehuvud
Stångehuvud is a nature reserve in Lysekil Municipality, Västra Götaland County, Sweden. It is located on the south tip of Stångenäset peninsula, adjacent the town of Lysekil. The reserve is known for its red Bohus granite. The granite was formed about 920 million years ago and the cliffs were later shaped by the ice during the last glacial period. Formerly an area for quarrying granite, the area was bought and preserved by Calla Curman at the beginning of the 19th century. She donated it to the Royal Swedish Academy of Sciences and in 1982, the nature reserve was created. In October 2020, 100 years after Calla Curman purchased Stångehuvud, two of the roads leading up to the nature reserve were named in honour of Calla and her husband Carl. History During the second part of the 19th century, the red granite was much in demand and quarrying in Stångehuvud went on for about 50 years. Seeing that the natural cliffs were decimated by the stone industry, socialite and femini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calla Curman
Calla Curman, née ''Lundström'' (1850–1935), was a Swedish writer, salon-holder and feminist. She was also the founder of Stångehuvud nature reserve and one of the five founders of the women's association Nya Idun. Family Calla Curman was born on 12 November 1850 in Jönköping, Sweden, the only child of wealthy industrialist and his wife Sofie Malmberg (1830–1897). She received in-home tutoring from a private tutor. At the age of 17, she married Adolf Liljenroth (1836–1874), a battalion physician, with whom she had two children, and . A few years after she was widowed by Liljenroth, Calla's parents took her on a trip to Italy. The educated Carl Curman, whom she had met on a visit with her mother to Lysekil during a few summer weeks in 1864, was invited to join them as a guide for the Italian trip. In 1877 she returned to Lysekil, then as Professor Carl Curman's guest. The following year they were married. He had worked as a spa doctor in Lysekil since 1859. With ...

Lysekil
Lysekil () is a Urban areas in Sweden, locality and the seat of Lysekil Municipality in Västra Götaland County, Sweden. It had about 7,600 inhabitants in 2018. Situated on the south tip of Stångenäs peninsula at the mouth of Gullmarn fjord, it has two nature reserves. Originally a small fishing village, it developed into a town for Fishing industry, fishing industries, Maritime transport, commercial shipping and trade during the 18th and 19th centuries. Stone industry based on the red Bohus granite from quarries in the town, was also vital to Lysekil up until the 1950s. One of Sweden's largest oil refineries, Preemraff Lysekil is situated outside the town. During the 19th century, Lysekil was established as a prominent seaside resort, spa and bathing resort and tourism still makes up a large part of the town's economy. History Lysekil is first mentioned in 1570. It was originally an estate belonging to Lyse farm further inland. The population lived mostly on fishing and Mari ...

Ice Sheet
In glaciology, an ice sheet, also known as a continental glacier, is a mass of glacial ice that covers surrounding terrain and is greater than . The only current ice sheets are in Antarctica and Greenland; during the Last Glacial Period at Last Glacial Maximum, the Laurentide Ice Sheet covered much of North America, the Weichselian ice sheet covered Northern Europe and the Patagonian Ice Sheet covered southern South America. Ice sheets are bigger than ice shelves or alpine glaciers. Masses of ice covering less than 50,000 km2 are termed an ice cap. An ice cap will typically feed a series of glaciers around its periphery. Although the surface is cold, the base of an ice sheet is generally warmer due to geothermal heat. In places, melting occurs and the melt-water lubricates the ice sheet so that it flows more rapidly. This process produces fast-flowing channels in the ice sheet — these are ice streams. The present-day polar ice sheets are relatively young in geol ...

Solar Panel
A solar cell panel, solar electric panel, photo-voltaic (PV) module, PV panel or solar panel is an assembly of photovoltaic solar cells mounted in a (usually rectangular) frame, and a neatly organised collection of PV panels is called a photovoltaic system or solar array. Solar panels capture sunlight as a source of radiant energy, which is converted into electric energy in the form of direct current (DC) electricity. Arrays of a photovoltaic system can be used to generate solar electricity that supplies electrical equipment directly, or grid-connected photovoltaic system, feeds power back into an alternate current (AC) electric grid, grid via an solar inverter, inverter system. History In 1839, the ability of some materials to create an electrical charge from light exposure was first observed by the French physicist Edmond Becquerel. Though these initial solar panels were too inefficient for even simple electric devices, they were used as an instrument to measure light. ...

Nordisk Familjebok
''Nordisk familjebok'' (, "Nordic Family Book") is a Swedish encyclopedia that was published in print from between 1876 and 1993, and that is now fully available in digital form via Project Runeberg at Linköping University. Despite their considerable age and relative obsolescence, the public domain editions of the encyclopedia remain important reference works in Finland, especially on Finnish Wikipedia. History First edition ''Nordisk familjebok'' began when Halmstad publisher hired an editor, linguist , in 1874 to publish a six-volume encyclopedia. Linder drew up a plan for the work, designed the editorial team and created a large circle of experts and literary figures, who submitted article proposals and wrote and reviewed them. Under Linder's direction, the articles were then edited to make them as formal, consistent and accurate as possible. Much attention was paid to Nordic subjects, mainly Swedish and Finnish, where sources and models were often lacking, so extensive ...

History Of Lighthouses
The history of lighthouses refers to the development of the use of towers, buildings, or other types of structure, as an aid to navigation for maritime pilots at sea or on inland waterways. Premodern era Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since raising the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs and promontories, unlike many modern lighthouses. Excavation at Kuntasi on the coast of what is now India has revealed a square watch tower with a ramp which would have originally been 10–12 meters which was used to guide boats coming to Kuntasi from Rann of Kutch, possibility of it being lighthouse cannot be ruled out. If so, the lighthouse would date from about 2000 BCE. Greek-Roman period According to Homeric legend, Palamed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerosene
Kerosene, paraffin, or lamp oil is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households. Its name derives from el, κηρός (''keros'') meaning "wax", and was registered as a trademark by Canadian geologist and inventor Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. The term kerosene is common in much of Argentina, Australia, Canada, India, New Zealand, Nigeria, and the United States, while the term paraffin (or a closely related variant) is used in Chile, eastern Africa, South Africa, Norway, and in the United Kingdom. The term lamp oil, or the equivalent in the local languages, is common in the majority of Asia and the Southeastern United States. Liquid paraffin (called mineral oil in the US) is a more viscous and highly refined product which is used as a laxative. Paraffin wax is a waxy solid extracted from pet ...

Calla (222982209)
''Calla'' is a genus of flowering plant in the family Araceae, containing the single species ''Calla palustris'' (bog arum, marsh calla, wild calla, squaw claw, and water-arumDickinson, T.; Metsger, D.; Bull, J.; & Dickinson, R. (2004) ROM Field Guide to Wildflowers of Ontario. Toronto:Royal Ontario Museum, p. 62.). Description It is a rhizomatous herbaceous perennial plant growing in bogs and ponds. The leaves are rounded to heart-shaped, long on a petiole, and broad. The greenish-yellow inflorescence is produced on a spadix about long, enclosed in a white spathe. The fruit is a cluster of red berries, each berry containing several seeds. The plant is very poisonous when fresh due to its high oxalic acid content, but the rhizome (like that of '' Caladium'', '' Colocasia'', and '' Arum'') is edible after drying, grinding, leaching and boiling. Taxonomy The genus formerly also included a number of other species, which have now been transferred to the separate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armeria Maritima
''Armeria maritima'', the thrift, sea thrift or sea pink, is a species of flowering plant in the family Plumbaginaceae. It is a compact evergreen perennial which grows in low clumps and sends up long stems that support globes of bright pink flowers. In some cases purple, white or red flowers also occur. It is a popular garden flower and has been distributed worldwide as a garden and cut flower. It does well in gardens designed as xeriscapes or rock gardens.

Vascular Plant
Vascular plants (), also called tracheophytes () or collectively Tracheophyta (), form a large group of land plants ( accepted known species) that have lignified tissues (the xylem) for conducting water and minerals throughout the plant. They also have a specialized non-lignified tissue (the phloem) to conduct products of photosynthesis. Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms (flowering plants). Scientific names for the group include Tracheophyta, Tracheobionta and Equisetopsida ''sensu lato''. Some early land plants (the rhyniophytes) had less developed vascular tissue; the term eutracheophyte has been used for all other vascular plants, including all living ones. Historically, vascular plants were known as "higher plants", as it was believed that they were further evolved than other plants due to being more complex organisms. However, this is an antiquated remnant of the obsolete scala naturae, and the term ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Striation
Glacial striations or striae are scratches or gouges cut into bedrock by glacial abrasion. These scratches and gouges were first recognized as the result of a moving glacier in the late 18th century when Swiss alpinists first associated them with moving glaciers. They also noted that if they were visible today that the glaciers must also be receding. Glacial striations are usually multiple, straight, and parallel, representing the movement of the glacier using rock fragments and sand grains, embedded in the base of the glacier, as cutting tools. Large amounts of coarse gravel and boulders carried along underneath the glacier provide the abrasive power to cut trough-like ''glacial grooves''. Finer sediments also in the base of the moving glacier further scour and polish the bedrock surface, forming a ''glacial pavement''. Ice itself is not a hard enough material to change the shape of rock but because the ice has rock embedded in the basal surface it can effectively abrade the b ...
