Pensford
Pensford is the largest village in the civil parish of Publow in Somerset, England. It lies in the Chew Valley, approximately south of Bristol, west of Bath and north of Wells. It is on the A37 road from Bristol to Shepton Mallet. Pensford was identified as being of special architectural and historic interest and was designated as a Conservation Area in May 1988. History The name Pensford is in all likelihood derived from Brythonic ''Penffordd'', meaning roughly 'top of the road' or 'the highest or furthest point of the road'. Alternatively, it may mean 'The animal pens by the ford' from the Old English ''pens'' and ''ford''. The parish of Pensford was part of the Keynsham Hundred, During the 14th to 16th centuries Pensford was a cloth centre based on local wool. On 24 June 1685 rebel forces camped at Pensford during the Monmouth Rebellion. During the 19th and 20th centuries the main industry was coal mining, with Pensford and the surrounding area forming a major ...

Agar
Agar ( or ), or agar-agar, is a jelly-like substance consisting of polysaccharides obtained from the cell walls of some species of red algae, primarily from ogonori (''Gracilaria'') and "tengusa" (''Gelidiaceae''). As found in nature, agar is a mixture of two components, the linear polysaccharide agarose and a heterogeneous mixture of smaller molecules called agaropectin. It forms the supporting structure in the cell walls of certain species of algae and is released on boiling. These algae are known as agarophytes, belonging to the Rhodophyta (red algae) phylum. The processing of food-grade agar removes the agaropectin, and the commercial product is essentially pure agarose. Agar has been used as an ingredient in desserts throughout Asia and also as a solid substrate to contain culture media for microbiological work. Agar can be used as a laxative; an appetite suppressant; a vegan substitute for gelatin; a thickener for soups; in fruit preserves, ice cream, and other desser ...

John Innes Centre
The John Innes Centre (JIC), located in Norwich, Norfolk, England, is an independent centre for research and training in plant and microbial science founded in 1910. It is a registered charity (No 223852) grant-aided by the Biotechnology and Biological Sciences Research Council (BBSRC), the European Research Council (ERC) and the Bill and Melinda Gates Foundation and is a member of the Norwich Research Park. In 2017, the John Innes Centre was awarded a gold Athena SWAN Charter award for equality in the workplace. History The John Innes Horticultural Institution was founded in 1910 at Merton Park, Surrey (now London Borough of Merton), with funds bequeathed by John Innes, a merchant and philanthropist. The Institution occupied Innes's former estate at Merton Park until 1945 when it moved to Bayfordbury, Hertfordshire. It moved to its present site in 1967.

Salmon
Salmon () is the common name for several list of commercially important fish species, commercially important species of euryhaline ray-finned fish from the family (biology), family Salmonidae, which are native to tributary, tributaries of the North Atlantic (genus ''Salmo'') and North Pacific (genus ''Oncorhynchus'') basin. Other closely related fish in the same family include trout, Salvelinus, char, Thymallus, grayling, Freshwater whitefish, whitefish, lenok and Hucho, taimen. Salmon are typically fish migration, anadromous: they hatch in the gravel stream bed, beds of shallow fresh water streams, migrate to the ocean as adults and live like sea fish, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water throughout their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn (biology), spawn, and tracking studies have shown this to be mostly true. A portion of a returning salmon run ma ...

Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aberystwyth
Aberystwyth () is a university and seaside town as well as a community in Ceredigion, Wales. Located in the historic county of Cardiganshire, means "the mouth of the Ystwyth". Aberystwyth University has been a major educational location in Wales since the establishment of University College Wales in 1872. The town is situated on Cardigan Bay on the west coast of Wales, near the confluence of the River Ystwyth and Afon Rheidol. Following the reconstruction of the harbour, the Ystwyth skirts the town. The Rheidol passes through the town. The seafront, with a pier, stretches from Constitution Hill at the north end of the Promenade to the harbour at the south. The beach is divided by the castle. The town is divided into five areas: Aberystwyth Town; Llanbadarn Fawr; Waunfawr; Llanbadarn; Trefechan; and the most populous, Penparcau. In 2011 the population of the town was 13,040. This rises to nearly 19,000 for the larger conurbation of Aberystwyth and Llanbadarn Fawr. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afon Rheidol
The Afon Rheidol is a river in Ceredigion, Wales, in length. The source is Plynlimon. Receiving an average annual rainfall of , Plynlimon is also the source of both the Wye and the Severn. Geography and geology The Rheidol rises in the headwaters of the Nant-y-moch Reservoir on the western flanks of Plynlimon, near the sources of the Wye and Severn. After flowing south to Ponterwyd on the increasingly deep valley, then southwest through Welsh Oak ancient woodland, it veers westwards to its confluence with the Afon Mynach, at Devil's Bridge, Ceredigion ( cy, Pontarfynach, lit. "bridge on the Mynach") and a spectacular waterfall. The river continues passing the abandoned workings of the Cwm Rheidol lead mine; one of many other metal mines in the valleya source of extracted metal pollution of the river and flows westwards before its confluence with the Afon Ystwyth and the estuary at Aberystwyth to drain into Cardigan Bay. In the late 1960s, when the mine was closed, a ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Pollution
Water pollution (or aquatic pollution) is the contamination of water bodies, usually as a result of human activities, so that it negatively affects its uses. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants are introduced into these water bodies. Water pollution can be attributed to one of four sources: sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. It can be grouped into surface water pollution (either fresh water pollution or marine pollution) or groundwater pollution. For example, releasing inadequately treated wastewater into natural waters can lead to degradation of these aquatic ecosystems. Water pollution can also lead to water-borne diseases for people using polluted water for drinking, bathing, washing or irrigation. Water pollution reduces the ability of the body of water to provide the ecosystem services (such as drinking water) that ...
