Stourhead () is a 1,072-hectare (2,650-acre) estate at the source of the River Stour in the southwest of the English county of Wiltshire, extending into Somerset. The estate is about 4 km (2+1⁄2 mi) northwest of the town of Mere and includes a Grade I listed 18th-century Neo-Palladian mansion, the village of Stourton, one of the most famous gardens in the English landscape garden style, farmland, and woodland. Stourhead has been part-owned by the National Trust since 1946. House The Stourton family had lived at the Stourhead estate for 500 years until they sold it to Sir Thomas Meres in 1714. His son, John Meres, sold it in 1717 to Henry Hoare, son of wealthy banker Sir Richard Hoare. The original manor house was demolished and a new house, one of the first of its kind, was designed by Colen Campbell and built by Nathaniel Ireson between 1721 and 1725.Over the next 200 years, the Hoare family collected many heirlooms, including a large library and art collection. In 1902, the house was gutted by fire but many of the heirlooms...

An icicle is a spike of ice formed when water falling from an object freezes. Formation and dynamics Icicles can form during bright, sunny, but subfreezing weather, when ice or snow melted by sunlight or some other heat source (such as a poorly insulated building), refreezes as it drips off under exposed conditions. Over time continued water runoff will cause the icicle to grow. Another set of conditions is during ice storms, when rain falling in air slightly below freezing slowly accumulates as numerous small icicles hanging from twigs, leaves, wires, etc. Thirdly, icicles can form wherever water seeps out of or drips off vertical surfaces such as road cuts or cliffs. Under some conditions these can slowly form the "frozen waterfalls" favored by ice climbers. Icicles form on surfaces which might have a smooth and straight, or irregular shape, which in turn influences the shape of an icicle. Another influence is melting water, which might flow toward the icicle in a straight line or which might flow from several directions. Impurities in the water can lead to ripples on...

A karyotype is the general appearance of the complete set of chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes and any abnormalities. A karyogram or idiogram is a graphical depiction of a karyotype, wherein chromosomes are generally organized in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotyping generally combines light microscopy and photography in the metaphase of the cell cycle, and results in a photomicrographic (or simply micrographic) karyogram. In contrast, a schematic karyogram is a designed graphic representation of a karyotype. In schematic karyograms, just one of the sister chromatids of each chromosome is generally shown for brevity, and in reality they are generally so close together that they look as one on photomicrographs as well unless the resolution is high enough to distinguish them. The study of whole sets of chromosomes is sometimes known as karyology...

In chemistry, a reagent ( ree-AY-jənt) or analytical reagent is a substance or compound added to a system to cause a chemical reaction, or test if one occurs. The terms reactant and reagent are often used interchangeably, but reactant specifies a substance consumed in the course of a chemical reaction. Solvents, though involved in the reaction mechanism, are usually not called reactants. Similarly, catalysts are not consumed by the reaction, so they are not reactants. In biochemistry, especially in connection with enzyme-catalyzed reactions, the reactants are commonly called substrates. Definitions Organic chemistry In organic chemistry, the term "reagent" denotes a chemical ingredient (a compound or mixture, typically of inorganic or small organic molecules) introduced to cause the desired transformation of an organic substance. Examples include the Collins reagent, Fenton's...

The Algarve (UK: , US: , Portuguese: [alˈɡaɾvɨ] (listen)) is the southernmost NUTS II region of continental Portugal. It has an area of 4,997 km2 (1,929 sq mi) with 467,495 permanent inhabitants and incorporates 16 municipalities (concelhos or municípios in Portuguese).The region has its administrative centre in the city of Faro, where both the region's international airport (IATA: FAO) and public university, the University of Algarve, are located. The region coincides with Faro District and is subdivided into two zones, one to the West (Barlavento) and another to the East (Sotavento). Tourism and related activities are extensive and make up the bulk of the Algarve's summer economy. Production of food, which includes fish and other seafood, as well as different types of fruit and vegetables, such as oranges, figs, plums, carob pods, almonds, avocados, tomatoes, cauliflowers, strawberries, and...

Philosophical Investigations (German: Philosophische Untersuchungen) is a work by the philosopher Ludwig Wittgenstein, published posthumously in 1953. Philosophical Investigations is divided into two parts, consisting of what Wittgenstein calls, in the preface, Bemerkungen, translated by Anscombe as "remarks".A survey among American university and college teachers ranked the Investigations as the most important book of 20th-century philosophy. Relation to Wittgenstein's body of work In its preface, Wittgenstein says that Philosophical Investigations can be understood "only by contrast with and against the background of my old way of thinking". That "old way of thinking" is to be found in the only book Wittgenstein published in his lifetime, the Tractatus Logico-Philosophicus. Many of the ideas developed in the Tractatus are criticised in the Investigations, while other ideas are further developed. The Blue and Brown Books, a set of notes...

Forage fish, also called prey fish or bait fish, are small pelagic fish which are preyed on by larger predators for food. Predators include other larger fish, seabirds and marine mammals. Typical ocean forage fish feed near the base of the food chain on plankton, often by filter feeding. They include particularly fishes of the order Clupeiformes (herrings, sardines, shad, hilsa, menhaden, anchovies, and sprats), but also other small fish, including halfbeaks, silversides, smelt such as capelin and goldband fusiliers. Forage fish compensate for their small size by forming schools. Some swim in synchronised grids with their mouths open so they can efficiently filter plankton. These schools can become immense shoals which move along coastlines and migrate across open oceans. The shoals are concentrated energy resources for the great marine predators. The predators are keenly focused on the shoals, acutely aware of their numbers and whereabouts, and make migrations themselves that can span thousands of miles to connect, or stay connected, with them.The ocean primary producers, mainly contained in plankton, produce food energy from the sun and are the...

An aurora (plural: auroras or aurorae), also commonly known as the polar lights, is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky.Auroras are the result of disturbances in the magnetosphere caused by the solar wind. Major disturbances result from enhancements in the speed of the solar wind from coronal holes and coronal mass ejections. These disturbances alter the trajectories of charged particles in the magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere). The resulting ionization and excitation of atmospheric constituents emit light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Most of the planets in the Solar System, some natural satellites, brown dwarfs, and even comets...

Palm oil is an edible vegetable oil derived from the mesocarp (reddish pulp) of the fruit of the oil palms. The oil is used in food manufacturing, in beauty products, and as biofuel. Palm oil accounted for about 33% of global oils produced from oil crops in 2014. Palm oils are easier to stabilize and maintain quality of flavor and consistency in processed foods, so are frequently favored by food manufacturers. On average globally, humans consumed 7.7 kg (17 lb) of palm oil per person in 2015. Demand has also increased for other uses, such as cosmetics and biofuels, creating more demand on the supply encouraging the growth of palm oil plantations in tropical countries. The use of palm oil has attracted the concern of environmental groups due to deforestation in the tropics where palms are grown, and has been cited as a factor in social problems due to allegations of human rights violations among growers. An industry group formed in 2004 to create more sustainable and ethical palm oil, through the Roundtable on Sustainable Palm Oil. However, very little palm oil is certified through the organization, and some groups have criticized it as...
