Salford, Greater Manchester
Salford () is a city and the largest settlement in the City of Salford metropolitan borough in Greater Manchester, England. In 2011, Salford had a population of 103,886. It is also the second and only other city in the metropolitan county after neighbouring Manchester. Salford is located in a meander of the River Irwell which forms part of its boundary with Manchester. The former County Borough of Salford, which also included Broughton, Pendleton and Kersal, was granted city status in 1926. In 1974 the wider Metropolitan Borough of the City of Salford was established with responsibility for a significantly larger region. Historically in Lancashire, Salford was the judicial seat of the ancient hundred of Salfordshire. It was granted a charter by Ranulf de Blondeville, 6th Earl of Chester, in about 1230, making Salford a free borough of greater cultural and commercial importance than its neighbour Manchester..

Flora Europaea
The ''Flora Europaea'' is a 5-volume encyclopedia of plants, published between 1964 and 1993 by Cambridge University Press. The aim was to describe all the national Floras of Europe in a single, authoritative publication to help readers identify any wild or widely cultivated plant in Europe to the subspecies level. It also provides information on geographical distribution, habitat preference, and chromosome number, where known. The ''Flora'' was released in CD form in 2001, and the Royal Botanic Garden Edinburgh have made an index to the plant names available online. History The idea of a pan-European Flora was first mooted at the 8th International Congress of Botany in Paris in 1954. In 1957, Britain's Science and Engineering Research Council provided grants to fund a secretariat of three people, and Volume 1 was published in 1964. More volumes were issued in the following years, culminating in 1980 with the monocots of Volume 5. The royalties were put into a trust fund admini ...

Cow Green Reservoir
Cow Green Reservoir is a long water reservoir forming part of the border between the historic counties of Westmorland and County Durham in northern England, built between 1967 and 1971 to supply the industries of Teesside. The reservoir acts as a river regulation reservoir releasing water into the River Tees during dry conditions so that it can be abstracted further downstream. These regulated flows allow six further reservoir levels to be maintained and these in turn provide water for industry and domestic use. Environmentally, this part of Upper Teesdale is of national importance and the plan to construct this reservoir had been strongly opposed by local conservationists, professional botanists and geologists. Their main concern was the protection of the rich flora and fauna of the district and especially rare alpine plants like the unique Teesdale violet. In the end, about a tenth of this plant's habitat was destroyed by the completion of the reservoir. The remaining area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Teesdale
Upper Teesdale is a Site of Special Scientific Interest (SSSI) in the west County Durham, England. It encompasses an extensive upland area that includes the headwaters of the River Tees and the surrounding catchment area upstream of the village of Langdon Beck. The site has a diverse mix of habitats, mainly dry heath, with wet heath and blanket bog, blanket mire in areas that are poorly drained. The Upper Teesdale SSSI is one of the most important botanical sites in Britain; the flora is exceptionally rich in species that are nationally rare, including some that are Relict (biology), relicts of the arctic-alpine environment of the last glacial period. The area supports internationally important populations of some wader, wading birds and is home to several rare invertebrates. Within the SSSI are several locations that are of national importance geologically, including one of only two known outcrops of 'sugar' limestone in Britain. The southern part of the SSSI largely coinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Primula
''Primula'' () is a genus of herbaceous flowering plants in the family Primulaceae. They include the primrose ('' P. vulgaris''), a familiar wildflower of banks and verges. Other common species are '' P. auricula'' (auricula), '' P. veris'' (cowslip), and '' P. elatior'' (oxlip). These species and many others are valued for their ornamental flowers. They have been extensively cultivated and hybridised (in the case of the primrose, for many hundreds of years). ''Primula'' are native to the temperate Northern Hemisphere, south into tropical mountains in Ethiopia, Indonesia, and New Guinea, and in temperate southern South America. Almost half of the known species are from the Himalayas. ''Primula'' has over 500 species in traditional treatments, and more if certain related genera are included within its circumscription.''Primula''. ...

Viola (plant)
''Viola'' is a genus of flowering plants in the violet family Violaceae. It is the largest genus in the family, containing between 525 and 600 species. Most species are found in the temperate Northern Hemisphere; however, some are also found in widely divergent areas such as Hawaii, Australasia, and the Andes. Some ''Viola'' species are perennial plants, some are annual plants, and a few are small shrubs. Many species, varieties and cultivars are grown in gardens for their ornamental flowers. In horticulture the term pansy is normally used for those multi-colored, large-flowered cultivars which are raised annually or biennially from seed and used extensively in bedding. The terms viola and violet are normally reserved for small-flowered annuals or perennials, including the wild species. Description Annual or perennial caulescent or acaulescent (with or without a visible plant stem above the ground) herbs, shrubs or very rarely treelets. In acaulescent taxa the foliage and flower ...

Reader (academic Rank)
The title of reader in the United Kingdom and some universities in the Commonwealth of Nations, for example India, Australia and New Zealand, denotes an appointment for a senior academic with a distinguished international reputation in research or scholarship. In the traditional hierarchy of British and other Commonwealth universities, reader (and principal lecturer in the new universities) are academic ranks above senior lecturer and below professor, recognising a distinguished record of original research. Reader is similar to a professor without a chair, similar to the distinction between ''professor extraordinarius'' and ''professor ordinarius'' at some European universities, professor and chaired professor in Hong Kong and "professor name" (or associate professor) and chaired professor in Ireland. Readers and professors in the UK would correspond to full professors in the United States.Graham WebbMaking the most of appraisal: career and professional development planning for le ...

House Of Lords
The House of Lords, also known as the House of Peers, is the Bicameralism, upper house of the Parliament of the United Kingdom. Membership is by Life peer, appointment, Hereditary peer, heredity or Lords Spiritual, official function. Like the House of Commons of the United Kingdom, House of Commons, it meets in the Palace of Westminster in London, England. The House of Lords scrutinises Bill (law), bills that have been approved by the House of Commons. It regularly reviews and amends bills from the Commons. While it is unable to prevent bills passing into law, except in certain limited circumstances, it can delay bills and force the Commons to reconsider their decisions. In this capacity, the House of Lords acts as a check on the more powerful House of Commons that is independent of the electoral process. While members of the Lords may also take on roles as government ministers, high-ranking officials such as cabinet ministers are usually drawn from the Commons. The House of Lo ...

Drying (food)
Food drying is a method of food preservation in which food is drying, dried (dehydrated or desiccation, desiccated). Drying inhibits the growth of bacteria, yeasts, and Mold (fungus), mold through the removal of water. Dehydration has been used widely for this purpose since ancient times; the earliest known practice is 12,000 B.C. by inhabitants of the modern Middle East and Asia regions."Historical Origins of Food Preservation". Accessed June 2011. Water is traditionally removed through evaporation by using methods such as air drying, sun drying, smoking or wind drying, although today electric food dehydrators or freeze-drying can be used to speed the drying process and ensure more consistent results.
