Royal Tunbridge Wells
Royal Tunbridge Wells is a town in Kent, England, southeast of central London. It lies close to the border with East Sussex on the northern edge of the High Weald, whose sandstone geology is exemplified by the rock formation High Rocks. The town was a spa in the Restoration and a fashionable resort in the mid-1700s under Beau Nash when the Pantiles, and its chalybeate spring, attracted visitors who wished to take the waters. Though its popularity as a spa town waned with the advent of sea bathing, the town still derives much of its income from tourism. The town has a population of around 56,500, and is the administrative centre of Tunbridge Wells Borough and in the parliamentary constituency of Tunbridge Wells. History Iron Age Evidence suggests that Iron Age people farmed the fields and mined the iron-rich rocks in the Tunbridge Wells area, and excavations in 1940 and 1957–61 by James Money at High Rocks uncovered the remains of a defensive hill-fort. It is tho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forestry
Forestry is the science and craft of creating, managing, planting, using, conserving and repairing forests, woodlands, and associated resources for human and environmental benefits. Forestry is practiced in plantations and natural stands. The science of forestry has elements that belong to the biological, physical, social, political and managerial sciences. Forest management play essential role of creation and modification of habitats and affect ecosystem services provisioning. Modern forestry generally embraces a broad range of concerns, in what is known as multiple-use management, including: the provision of timber, fuel wood, wildlife habitat, natural water quality management, recreation, landscape and community protection, employment, aesthetically appealing landscapes, biodiversity management, watershed management, erosion control, and preserving forests as " sinks" for atmospheric carbon dioxide. Forest ecosystems have come to be seen as the most important componen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Potential
Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure and matrix effects such as capillary action (which is caused by surface tension). The concept of water potential has proved useful in understanding and computing water movement within plants, animals, and soil. Water potential is typically expressed in potential energy per unit volume and very often is represented by the Greek letter ψ. Water potential integrates a variety of different potential drivers of water movement, which may operate in the same or different directions. Within complex biological systems, many potential factors may be operating simultaneously. For example, the addition of solutes lowers the potential (negative vector), while an increase in pressure increases the potential (positive vector). If the flow is not restricte ...

Plant Ecology
Plant ecology is a subdiscipline of ecology which studies the distribution and abundance of plants, the effects of environmental factors upon the abundance of plants, and the interactions among and between plants and other organisms. Examples of these are the distribution of temperate deciduous forests in North America, the effects of drought or flooding upon plant survival, and competition among desert plants for water, or effects of herds of grazing animals upon the composition of grasslands. A global overview of the Earth's major vegetation types is provided by O.W. Archibold. He recognizes 11 major vegetation types: tropical forests, tropical savannas, arid regions (deserts), Mediterranean ecosystems, temperate forest ecosystems, temperate grasslands, coniferous forests, tundra (both polar and high mountain), terrestrial wetlands, freshwater ecosystems and coastal/marine systems. This breadth of topics shows the complexity of plant ecology, since it includes plants from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Scotsman
''The Scotsman'' is a Scottish compact newspaper and daily news website headquartered in Edinburgh. First established as a radical political paper in 1817, it began daily publication in 1855 and remained a broadsheet until August 2004. Its parent company, JPIMedia, also publishes the ''Edinburgh Evening News''. It had an audited print circulation of 16,349 for July to December 2018. Its website, Scotsman.com, had an average of 138,000 unique visitors a day as of 2017. The title celebrated its bicentenary on 25 January 2017. History ''The Scotsman'' was launched in 1817 as a liberal weekly newspaper by lawyer William Ritchie and customs official Charles Maclaren in response to the "unblushing subservience" of competing newspapers to the Edinburgh establishment. The paper was pledged to "impartiality, firmness and independence". After the abolition of newspaper stamp tax in Scotland in 1855, ''The Scotsman'' was relaunched as a daily newspaper priced at 1d and a circul ...

Postdoctoral Research
A postdoctoral fellow, postdoctoral researcher, or simply postdoc, is a person professionally conducting research after the completion of their doctoral studies (typically a PhD). The ultimate goal of a postdoctoral research position is to pursue additional research, training, or teaching in order to have better skills to pursue a career in academia, research, or any other field. Postdocs often, but not always, have a temporary academic appointment, sometimes in preparation for an academic faculty position. They continue their studies or carry out research and further increase expertise in a specialist subject, including integrating a team and acquiring novel skills and research methods. Postdoctoral research is often considered essential while advancing the scholarly mission of the host institution; it is expected to produce relevant publications in peer-reviewed academic journals or conferences. In some countries, postdoctoral research may lead to further formal qualificati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NATO
The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is ''animus in consulendo liber'' (Latin for "a mind unfettered in deliberation"). NATO's main headquarters are located in Brussels, Belgium, while NATO ...

Quercus Petraea
''Quercus petraea'', commonly known as the sessile oak, Cornish oak, Irish Oak or durmast oak, is a species of oak tree native to most of Europe and into Anatolia and Iran. The sessile oak is the national tree of Ireland, and an unofficial emblem in Wales and Cornwall. Description The sessile oak is a large deciduous tree up to tall, in the white oak section of the genus (''Quercus'' sect. ''Quercus'') and similar to the pedunculate oak (''Q. robur''), with which it overlaps extensively in range. The leaves are long and broad, evenly lobed with five to six lobes on each side and a petiole. The male flowers are grouped into catkins, produced in the spring. The fruit is an acorn long and broad, which matures in about six months. Comparison with pedunculate oak Significant botanical differences from pedunculate oak (''Q. robur'') include the stalked leaves, and the stalkless (sessile) acorns from which one of its common names is derived. It occurs in upl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Botany
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning " pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – ed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
