Verrucaria Muralis
''Verrucaria muralis'' is a species of saxicolous (rock-dwelling, crustose lichen in the family Verrucariaceae. It is a common species with an almost cosmopolitan distribution, occurring in an altitudinal range extending from the lowlands to the subalpine zone. It grows on calcareous rocks and walls. It was first formally described as a new species in 1803 by Swedish lichenologist Erik Acharius. Description The epilithic thallus of ''Verrucaria muralis'' is thin (0.02–0.2 mm thick,) and greyish. It has medium-sized hemispherically protruding perithecia, more or less spherical pale exciples with a well-developed involucrellum of medium thickness that usually reaches down to the middle part of the perithecium (rarely deeper). The hymenium has sparsely branched-anastomosing paraphyses of about 30–50 μm in length, and spores measuring 18–25 by 8–13 μm. In a study of lichen growth rate, Bruce Fink reported in 1917 that it increased in diameter 0.6  ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Renkum
Renkum () is a municipality and a town in the eastern Netherlands. The municipality had a population of in and has a land area of . Renkum is situated along the river Rhine. The municipality Renkum is part of the ''Stadsregio'' (English: City region) Arnhem-Nijmegen. The surrounding of the municipality are mainly forest and river forelands. In the forest one can find tumulus of thousand years old. Findings from these tumulus can be seen in the Historic museum in Arnhem. History Renkum is more than a thousand years old. The thousand-year anniversary was celebrated in 1970. In the early days, the name was written as ''Redinchem''. In the 19th century Renkum developed itself. There existed six paper mills, three water-cornmills and one water-oil mill. There were two factories, a treacle factory and a potato starch-flour factory. There was also a beer brewery and a tavern ''de Bok''. Nowadays there is still paper industry The company is ''Parenco B.V.'', acquired by H2 Equity P ...

Splash Zone
In offshore construction, the splash zone is the transition from air to water when lowering heavy burdens into the sea. The overall efforts applied on the crane change dramatically when the load starts touching water, up to the point where it is completely submerged. Its buoyancy Buoyancy (), or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the p ... reduces the static mass that the crane has to support, but contact with the waves creates widely fluctuating dynamic forces. Simulation of these changing efforts are necessary to correctly dimension cranes and lifting equipment. See for examplDNV-RP-H103(Det Norske Veritas recommended practices) for a mention of the piston effect created in the splash zone between two walls. Offshore engineering {{Engineering-stub ...

Verrucaria
''Verrucaria'' is a genus of lichenized (lichen-forming) fungi in the family Verrucariaceae. Taxonomy The genus was circumscribed by German botanist Heinrich Adolph Schrader in 1794, with '' Verrucaria rupestris'' assigned as the type species. In his brief diagnosis of the genus, Schrader mentioned the more or less spherical (''subglobose''), closed ascomata, and the crustose thallus. The genus name is derived from the Latin word ''verruca'' (meaning "wart") and the suffix ''-aria'' (meaning "belonging to" or "possession"). Ecology As of 2015, there were 16 ''Verrucaria'' species classified as marine species: '' V. adguttata'', '' V. allantoidea'', '' V. ceuthocarpa'', '' V. corallensi'', '' V. ditmarsica'', '' V. erichsenii'', '' V. halizoa'', '' V. halochlora'', '' V. microsporoides'', '' V. paulula'', '' V. psychrophila'', '' V. sandstedei'', '' V. serpuloides'', '' V. sessilis'', '' V. subdiscreta'', ...

Species Fungorum
''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are ''MycoBank'' and ''Fungal Names''. Current names in ''Index Fungorum'' (''Specie ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Baltic Countries
The Baltic states, et, Balti riigid or the Baltic countries is a geopolitical term, which currently is used to group three countries: Estonia, Latvia, and Lithuania. All three countries are members of NATO, the European Union, the Eurozone, and the OECD. The three sovereign states on the eastern coast of the Baltic Sea are sometimes referred to as the "Baltic nations", less often and in historical circumstances also as the "Baltic republics", the "Baltic lands", or simply the Baltics. All three Baltic countries are classified as high-income economies by the World Bank and maintain a very high Human Development Index. The three governments engage in intergovernmental and parliamentary cooperation. There is also frequent cooperation in foreign and security policy, defence, energy, and transportation. The term "Baltic states" ("countries", "nations", or similar) cannot be used unambiguously in the context of cultural areas, national identity, or language. While the majority ...

Fennoscandia
__NOTOC__ Fennoscandia (Finnish language, Finnish, Swedish language, Swedish and no, Fennoskandia, nocat=1; russian: Фенноскандия, Fennoskandiya) or the Fennoscandian Peninsula is the geographical peninsula in Europe, which includes the Scandinavian Peninsula, Scandinavian and Kola Peninsula, Kola peninsulas, mainland Finland, and Karelia. Administratively this roughly encompasses the mainlands of Finland, Norway and Sweden, as well as Murmansk Oblast, much of the Republic of Karelia, and parts of northern Leningrad Oblast in Russia. Its name comes from the Latin words ''Fennia'' (Finland) and ''Scandia'' (Scandinavian). The term was first used by the Finnish geologist Wilhelm Ramsay in 1898. Geologically, the area is distinct because its bedrock is Archean granite and gneiss with very little limestone, in contrast to adjacent areas in Europe. The similar term Fenno-Scandinavia is sometimes used as a synonym for Fennoscandia. Both terms are sometimes used in Englis ...

Lichenicolous Fungus
A lichenicolous fungus is a parasitic fungus that only lives on lichen as the host. A lichenicolous fungus is not the same as the fungus that is the component of the lichen, which is known as a lichenized fungus. They are most commonly specific to a given fungus as the host, but they also include a wide range of pathogens, saprotrophs, and commensals. It is estimated there are 3000 species of lichenicolous fungi. More than 1800 species are already described among the Ascomycota and Basidiomycota.Lichenicolous Fungi: Interactions, Evolution, and Biodiversity, Lawrey, James D.; Diederich, Paul. The Bryologist 106(1), pp. 80 120, 2003/ref> More than 95% of lichenicolous fungi described as of 2003 are ascomycetes, in 7 class (biology), classes and 19 order (biology), orders. Although basidiomycetes have less than 5% of lichenicolous lichen species, they represent 4 classes and 8 orders. Many lichenicolous species have yet to be assigned a phylogenetic position as of 2003. See also * ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
