Shaft sinking. Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects.Shaft sinking is one of the most difficult of all mine development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Shafts may be sunk by conventional drill and blast or mechanised means.Historically, mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve.

Shaft sinking. of mining contractors called sinkers. Today shaft sinking contractors are concentrated in Canada, Germany, China and South Africa.The modern shaft sinking industry is gradually shifting further towards greater mechanisation, recent innovations in the form of full-face shaft boring (akin to a vertical tunnel boring machine) have shown promise but the use of this method is, as of 2019, not widespread.## Mine shafts.Mine shafts are vertical or near-vertical tunnels, which are "sunk" as a means of accessing an underground ore body, during of the development of an underground mine.The shape (in plan view), dimensions and depth of mine shafts vary greatly.

Shaft sinking. in response to the specific needs of the mine they are part of and the geology they are sunk through. For example, in North and South America, smaller shafts are designed to be rectangular in plan view with timber supports. Larger shafts are round in plan and are concrete lined.Mine shafts may be used for a variety of purposes, including as a means of escape in the event of an emergency underground and allowing for the movement of: People Materials Mine services (such as compressed air, water, backfill, power, communications and fuel) Ventilation air Broken rock (in the form of.

Shaft sinking. payable ore, or non payable waste) Or any combination of the aboveWhen the top of the excavation is the ground surface, it is referred to as a "shaft"; when the top of the excavation is underground, it is called a "winze" or a "sub-shaft". Small shafts may be excavated upwards from within an existing mine as long as there is access at the bottom, in which case they are called "raises".A shaft may be either vertical or inclined (between 80 and 90 degrees to the horizontal), although most modern mine shafts are vertical. If access exists at the bottom of.

Shaft sinking. the proposed shaft, and ground conditions allow, then raise boring may be used to excavate the shaft from the bottom up; such shafts are called "borehole shafts".Following the Hartley Colliery disaster where the single shaft at the mine became blocked, the United Kingdom made single shaft mines illegal in 1862, establishing the practice that all underground mines must have a "a second means of egress". Many other global mining jurisdictions have adopted this rule and shafts are therefore often found in pairs (although there are multiple alternative methods of providing a second means of egress).The current the deepest single lift.

Shaft sinking. (i.e. continuous) mine shaft in the world is the 2991m deep, main shaft at South Deep Mine in South Africa, owned by Gold Fields Limited, which, along with its twin ventilation shafts, took ten years to sink and equip.## Parts of a mine shaft.The most visible feature of a traditionally-built mine shaft is the headframe (or winding tower, poppet head or pit head) which stands above the shaft. Depending on the type of hoist (or winder) used, the top of the headframe will either house a hoist motor or a sheave wheel (with the hoist motor mounted on the ground).

Shaft sinking. The headframe will also typically contain bins for storing ore being transferred to the processing facility.At ground level beneath and around the headframe is the Shaft Collar (also called the Bank or Deck), which provides the foundation necessary to support the weight of the headframe and provides a means for workers, materials and services to enter and exit the shaft. Collars are usually massive reinforced concrete structures with more than one level. If the shaft is used for mine ventilation, a plenum space or casing is incorporated into the collar to ensure the proper flow of air into and out.

Shaft sinking. of the mine.Beneath the collar the part of the shaft which continues into the ground is called the "shaft barrel".At locations where the shaft barrel meets horizontal workings there is a "shaft station" (or inset) which allows men, materials and services to enter and exit the shaft. From the station tunnels (drifts, galleries or levels) extend towards the ore body, sometimes for many kilometers. The lowest shaft station is most often the point where rock leaves the mine levels and is transferred to the shaft, if so a "loading pocket" is excavated on one side of the shaft at this.

Shaft sinking. location to allow transfer facilities to be built.Beneath the lowest shaft station the shaft continues on for some distance, this area is referred to as the "shaft bottom". A tunnel called a "ramp" typically connects the bottom of the shaft with the rest of the mine, this ramp often contains the mine's water handling facility, called the "sump", as water will naturally flow to the lowest point in the mine.## Shaft lining.Many (although not all) shafts are lined following excavation and the installation of temporary ground support.The shaft lining performs several functions; it is first and foremost a safety feature.

Shaft sinking. preventing loose or unstable rock from falling into the shaft, then a place for shaft sets to bolt into, and lastly a smooth surface to minimise resistance to airflow for ventilation.Final choice of shaft lining is dependent on the geology of the rock which the shaft passes through, some shafts have several liners sections as required Where shafts are sunk in very competent rock there may be no requirement for lining at all, or just the installation of welded mesh and rock bolts. The material of choice for shaft lining is mass concrete which is poured behind "shaft forms" in.

Shaft sinking. lifts of 6 m as the shaft advances (gets deeper).Shotcrete, fibrecrete, brick, cast iron tubing, and precast concrete segments have all been used at one time or another. Additionally, the use of materials like bitumen and even squash balls have been required by specific circumstances. In extreme cases, particularly when sinking through halite, composite liners consisting of two or more materials may be required.The shaft liner does not reach right to the bottom of the shaft during sinking, but lags behind by a fixed distance. This distance is determined by the methodology of excavation and the design thickness of the.

Shaft sinking. permanent liner. To ensure the safety of persons working on the shaft bottom temporary ground support is installed, usually consisting of welded mesh and rock bolts. The installation of the temporary ground support (called "bolting") is among the most physically challenging parts of the shaft sinking cycle as bolts must be installed using pneumatic powered rock drills.For this reason, and to minimise the number of persons on the shaft bottom a number of projects have successfully switched to shotcrete for this temporary lining. Research and development in this area is focusing on the robotic application of shotcrete and the commercialisation.

Shaft sinking. of thin sprayed polymer liners.## Shaft compartments.Where the shaft is to be used for hoisting it is frequently split into multiple compartments by "shaft sets", these may be made of either timber or steel. Vertical members in a shaft set are called "guides", horizontal members are called "buntons". For steel shaft guides, the main two options are hollow structural sections and top hat sections. Top hat sections offer a number of advantages over hollow structural sections including simpler installation, improved corrosion resistance and increased stiffness. Mine conveyances run on the guides in a similar way to how a steel roller.

Shaft sinking. coaster runs on its rails, both having wheels which keep them securely in place.Some shafts do not use guide beams but instead utilize steel wire rope (called "guide rope") kept in tension by massive weights at shaft bottom called "cheese weights" (because of their resemblance to a truckle or wheel of cheese) as these are easier to maintain and replace.The largest compartment is typically used for the "mine cage", a conveyance used for moving workers and supplies below the surface, which is suspended from the hoist on steel wire rope. It functions in a similar manner to an elevator. Cages.

Shaft sinking. may be single-, double-, or rarely triple-deck, always having multiple redundant safety systems in case of unexpected failure.The second compartment is used for one or more skips, used to hoist ore to the surface. Smaller mining operations use a skip mounted underneath the cage, rather than a separate device, while some large mines have separate shafts for the cage and skips. The third compartment is used for an emergency exit; it may house an auxiliary cage or a system of ladders. An additional compartment houses mine services such as high voltage cables and pipes for transfer of water, compressed air.

Shaft sinking. or diesel fuel.A second reason to divide the shaft is for ventilation. One or more of the compartments discussed above may be used for air intake, while others may be used for exhaust. Where this is the case a steel or concrete wall called a "brattice" is installed between the two compartments to separate the air flow. At many mines there are one or more complete additional separate "auxiliary shafts" with separate head gear and cages.## Shaft construction.The lowest point in a sinking shaft is known as "shaft bottom", shaft projects differ from some other forms of mine development in.

Shaft sinking. that all activities that take place on shaft bottom become part of the critical path for the project schedule. The infrastructure required to sink a shaft is referred to a "the sinking set-up".It is typical for progress (the "sinking rate") in the sinking phase (that is excavation, ground support and lining) of a shaft project to follow a learning curve as the project team repeat the same series of activities over and over in what is called "the sinking cycle", eventually approaching the theoretical maximum rate for that sinking set up over time. The use of experienced shaft sinkers is.

Shaft sinking. necessary to reduce the length of this learning curve and thus the duration of the project as much as possible.Key to a successful shaft sinking project are: Getting the various components of the sinking set-up correct and installed at the right time. Having experienced people involved from as early in the project as possible Using the available time on shaft bottom as efficiently as possible.Although significant emphasis is placed on the rate of progress of a project sinking cycle by shaft sinkers, sinking is only one of a number of phases in the conventional construction of a new shaft, as.

Shaft sinking. follows; "Box Cut Excavation". A box cut is a large square or rectangular excavation typically completed using earthmoving equipment down to bedrock, inside which the shaft collar will be constructed. Having the loads imposed by the collar, headframe and hoisting plant transferred into solid rock is necessary to prevent unplanned subsidence. Where the depth of bedrock is to great to for a box cut to economically viable, or the bedrock is not strong enough, civil engineering techniques such as diaphragm walls or concrete piles may be used to create a deep foundation instead. "Pre-Sink". The pre-sink is the excavation and.

Shaft sinking. support of the first 60 – 100 meters of the shaft barrel, often completed smaller equipment such as handheld, pneumatic drilling equipment to drill holes for basting and ground support and mini-excavators for mucking. During the pre-sink hoisting of muck and equipment is usually performed by a mobile crane on surface. It is necessary to sink this part of the shaft first so that the Galloway, a multi-level working platform may be installed with enough vertical distance to shaft bottom that it will not be damaged by fly rock during blasting. "Collar Construction". From the bottom of the box-cut, the.

Shaft sinking. shaft collar is constructed bottom up in a planned series of concrete pours. "Galloway (Sinking Stage) Construction & Installation." The Galloway (also known as a Sinking Stage or Scaffold) is a multi-level working platform, suspended in the shaft from winches located on surface. The Galloway allows sinkers to efficiently work on differing levels as required by the various tasks of the sinking cycle. It is typical for the Galloway to be constructed off to one side of the shaft and lowered into the pre-sink with a crane in as complete a state as possible. Once in place the Galloway is.

Shaft sinking. "chaired" (suspended from the shaft collar) while the headframe is built above, often protected by a bulkhead. "Headframe & Hoist House Construction." With the collar constructed and the Galloway installed the headframe and hoist (or winder) houses may be constructed and the hoist and winch ropes installed. Headframes may be either steel or concrete and their design will determine how they are constructed. The Galloway is moved in the shaft by means of winches, which move slowly and are rated for significant loads, while the sinking buckets (or kibbles) are moved in the shaft by the sinking hoist, which moves.

Shaft sinking. quickly and is rates for less load that the winches. To protect the hoist(s) and winches and the sensitive electronics which are used to control their operation they are normally installed inside of a build called a hoist (or winder) house. "Commissioning Sinking Set Up." The Sinking set-up must then be commissioned to ensure that all parts are operating as planned. "Full Sink". The activities of the sinking cycle (excavation, installation of temporary ground support, placement of the shaft lining and extending shaft services) all take place in this phase of construction. In a shaft where there are to be.

Shaft sinking. multiple working levels, shaft stations and station stubs (short lengths of horizontal tunnel leading away from the station) will be developed by the sinkers on the way down. As the equipment to excavate these stations must be small enough to fit through the openings in the Galloway, the rate of advance in developing the station stubs is typically low, compared to what can be achieved with full size mining equipment so station stubs are typically kept as short as possible. "Shaft Equipping & Headframe Changeover." Once the shaft reaches the final design depth, the shaft is stripped of any temporary.

Shaft sinking. services, the Galloway cut up or modified to suit the installation of the permanent shaft set-up, the shaft sets (if required) installed and the headframe / winders modified to allow for permanent hoisting. Any permanent conveyances will be installed at this stage. "Commissioning Permanent Set Up." The Permanent set-up must then be commissioned to ensure that all parts are operating as planned before being handed over to the new owner.As with the depth and design of shafts significant variations do exist in this sequence depending on local conditions, for example in that hard Canadian Shield rocks which dominate shaft sinking.

Shaft sinking. in Canada a deep and complex shaft collar is unnecessary as the bedrock is both strong and close to surface. This reduces the amount of time typically required to establish the shaft collar.Traditionally sinking contractors would build a temporary headframe for the sinking set up, which would then be dismantled to make way for a permanent headframe. With the growth in complexity and duration of shaft sinking projects over time it has become more common to incorporate more of the permanent shaft set-up into the sinking phase. This results in a reduced overall project duration, as for example, if the.

Shaft sinking. service piping used to sink the shaft does not need to be stripped out to make way for permanent piping.With the advancements made in raise boring technology, raise borers have been used to create a pilot hole for shaft sinking, where access exists at the bottom of the new shaft, in this case the sinking phase is dedicated to enlarging this pilot hole to full diameter (a process usually called "slashing"). This methodology can be considerably faster than full face sinking as muck (waste rock) from sinking falls down the pilot hole and is handled using existing mine infrastructure off.

Church of the Assumption of the Virgin Mary (Most). The Church of the Assumption of the Virgin Mary (Czech: "kostel Nanebevzetí Panny Marie") is a late Gothic church building in Most, a city in the Ústí nad Labem Region of the Czech Republic.## Previous building.The deanery church in Most, which stood in the middle of the church yard near the road to Žatec, burned down in 1515, and only the eastern crypt and the inner peripheral brickwork of the western tower could be saved. (The foundation of this church is indicated in 1253 till 1257 and indirectly proven by a document of pope Bonifacio VIII from 1296. The construction.

Church of the Assumption of the Virgin Mary (Most). was originally an early Gothic basilica of three naves.)## Construction.The building of the new church began on August 20, 1517, when the cornerstone was laid, and was financed by individual donors. The designer was Jakob Heilmann from Schweinfurt. He proposed the church as a big hall of three naves, with inside supports, a pentagonal presbytery and a prismatic tower with a gallery in the main elevation. The northern wall contains a vestibule, and a sacristy is located in the north-western wall.During the first year, demolition work was carried out. Heilmann handed over the project in 1518, and control of the.

Church of the Assumption of the Virgin Mary (Most). building works was taken over initially by the foreman Jörg (Georg) of Maulbron and later by another foreman called Peter (possibly Heilmann). The vaults of the peripheral chapels were finished during the second decade of the 16th century, then the inner pillars were erected and in 1532 the church was prepared for vaulting. Then, the windows were placed and the vaulting ribs were dressed. The carcassing was finished in 1549 and the renaissance portals installed in the second half of the 16th century. Unfortunately the church burnt out in 1578, and was finally repaired by 1602. The church was consecrated.

Church of the Assumption of the Virgin Mary (Most). in 1597.## Later repairs.A new roof was put on the church in 1650. The actual main altar was constructed during 1735–1739. The altar decoration was made in the workshop of the sculptor Bartolomeo Eder and the main altar picture was produced by Josef Kramolín - both in 1773. A boundary wall round the cemetery, church and the ossuary was demolished in 1840. Another big repair was made during 1880–1883, during which the interior was reshaped into the Gothic style, and a part of the baroque inventory was removed. New gothic paint was used, and equipment was installed in the new.

Church of the Assumption of the Virgin Mary (Most). gothic style. The plaster renovation of the outer walls, as well as a treatment of the stone parts was made in 1932.## Transport of the building.During the sixties, Most's historic center was completely destroyed to make room for the expanding lignite mines, a process that lasted until 1980. Unlike other historical buildings it was decided to save the church by moving it away from mining area.An expert committee was set up by the Ministry of Culture of Czechoslovakia to supervise the project, presided over by academician Stanislav Bechyně. From 1969 the committee was led by Alois Myslivec. The important specialist-adviser.

Church of the Assumption of the Virgin Mary (Most). was Emmanuel Gendel (1903-1994), well-known Soviet construction engineer, who subsequently became the USSR's leading specialist in moving buildings in the 1930s.To move the building, a variant on a bow path was chosen. The transfer was overseen by the firm Transfera Praha, an organisation of the Czech Ministry of Culture, and was performed by Průmstav Pardubice and Škoda Plzeň.Prior to moving the building, the peripheral masonry, the bearing and supporting pillars were reinforced, and the remainder of the western tower was demolished. The church circumference was reinforced by a concrete ring and the church was gripped by a steel framework construction.

Church of the Assumption of the Virgin Mary (Most). on the inner as well as outer sides. The preparation work lasted seven years, as it was also necessary to demolish all houses in the transfer path and fill in the former opencast mine.53 transport trucks were set on special rails, which were inserted under all statically important points of the building. These transport trucks worked using computer controlled hydraulics, as were four booms used to pull the church. During movement of the church on the road section, rails which had already been passed over were moved from behind the building to in front of it, allowing them to be.

Church of the Assumption of the Virgin Mary (Most). used again.Between September 30 and October 27, 1975, the church was moved a distance of 841.1 meters at a velocity of 1–3 centimeters per minute to the vicinity of the old hospital with a small church of the Holy Spirit, and it was set on an iron-concrete two-storied foundation. After the move was completed, restoration work went on until 1988, and the church was solemnly consecrated again in 1993.This building was mentioned in Guinness Book of World Records as the heaviest building ever moved on wheels (12 700 t).## Architecture.The church is 60 m long and 30 m large, has.

Church of the Assumption of the Virgin Mary (Most). only one tower, conforming to the South-German late-gothic layout. Its interior walls are plain, and the peripheral walls are broken by two rows of windows. The lower windows belong to the individual chapels and the upper ones belong to the flank naves of the hall. The inside of the church forms a big hall, divided into three naves by seven pairs of octahedral columns. Between the counterforts are 16 chapels, two side vestibules, a sacristy, a double worm staircase on the eastern side and a worm staircase on the western side. Each of the chapels has its own ribbed vault.

Puente de Piedra (Zaragoza). The Puente de Piedra () is a bridge across the river Ebro in Zaragoza, Spain. The Puente de Piedra is also called the Bridge of Lions because since 1991 four lions (symbols of the city) have been placed on the pillars at each end of the bridge. The lion statues were designed by Francisco Rallo Lahoz.## History.Beginning in the 12th century the citizens of Zaragoza tried to build a bridge across the Ebro. In 1401–1440, the Puente de Piedra was built under the direction of Gil de Menestral. The flood in 1643 destroyed two central bridge spans. The bridge then.

The gleba becomes brown and powdery as the specimen matures. Small dark hairlike threads (rhizomorphs) extend from the base of the fruit body into the substrate. The rhizomorphs are fragile, and often break off after maturity.The spores are spherical or nearly so, reddish-brown, thick-walled and verrucose (covered with warts and spines). The spores' dimensions are 7–11 µm; the warts are about 1 µm long. The spores are non-amyloid, and will not stain with iodine.

Astraeus hygrometricus. moist soil. The spore ornamentation of "A. odoratus" is also distinct from "A. hygrometricus", with longer and narrower spines that often joined. "A. asiaticus" has an outer peridial surface covered with small granules, and a gleba that is purplish-chestnut in color, compared to the smooth peridial surface and brownish gleba of "A. hygrometricus". The upper limit of the spore size of "A. asiaticus" is larger than that of its more common relative, ranging from 8.75 to 15.2 μm. "A. koreanus" (sometimes named as the variety "A. hygrometricus" var. "koreanus"; see Taxonomy) differs from the more common form in its smaller.

Muskrat. The muskrat ("Ondatra zibethicus") is a medium-sized semiaquatic rodent native to North America and an introduced species in parts of Europe, Asia, and South America. The muskrat is found in wetlands over a wide range of climates and habitats. It has important effects on the ecology of wetlands, and is a resource of food and fur for humans.Adult muskrats weigh 0.6 - 2 (kg), with a body length of 20 - 35 (cm). They are covered with short, thick fur of medium to dark brown color. Their long tails, covered with scales rather than hair, are their main means of.

Their tail functions as a rudder, controlling the direction they swim in.## Distribution and ecology.Muskrats are found over most of Canada and the United States and a small part of northern Mexico. They were introduced to Europe in the beginning of the 20th century and have become an invasive species in northwestern Europe. They mostly inhabit wetlands, areas in or near saline and freshwater wetlands, rivers, lakes, or ponds.

They are able to live alongside streams which contain the sulfurous water that drains away from coal mines. Fish and frogs perish in such streams, yet muskrats may thrive and occupy the wetlands. Muskrats also benefit from human persecution of some of their predators.The muskrat is classed as a "prohibited new organism" under New Zealand's Hazardous Substances and New Organisms Act 1996, preventing it from being imported into the country.The trematode "Metorchis conjunctus" can also infect muskrats.## Invasiveness status.In Europe, the.

For example, modern medicine has made leaps in preventing infectious diseases in part due to improved water and sewage treatment. This is obvious in the marked rises in life expectancy.## Technological advancement in underdeveloped countries.Some of the most dramatic technological benefits are seen in underdeveloped countries. For instance, cabling for landline telephone service is expensive and requires a lot of time to complete, especially in the most remote areas. Introduction of cellphone service, on the other hand, is much cheaper and dramatically improves.

Lettuce. Lettuce ("Lactuca sativa") is an annual plant of the family Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds. Lettuce is most often used for salads, although it is also seen in other kinds of food, such as soups, sandwiches and wraps; it can also be grilled. One variety, celtuce (asparagus lettuce), is grown for its stems, which are eaten either raw or cooked. In addition to its main use as a leafy green, it has also gathered religious and medicinal significance over centuries of human consumption. Europe and North America originally.

Lettuce. appeared often in medieval writings, including several herbals. The 16th through 18th centuries saw the development of many varieties in Europe, and by the mid-18th century, cultivars were described that can still be found in modern gardens.Generally grown as a hardy annual, lettuce is easily cultivated, although it requires relatively low temperatures to prevent it from flowering quickly. It can be plagued by numerous nutrient deficiencies, as well as insect and mammal pests, and fungal and bacterial diseases. "L. sativa" crosses easily within the species and with some other species within the genus "Lactuca". Although this trait can be a.

Lettuce. problem to home gardeners who attempt to save seeds, biologists have used it to broaden the gene pool of cultivated lettuce varieties.Lettuce is a rich source of vitamin K and vitamin A, and a moderate source of folate and iron. Contaminated lettuce is often a source of bacterial, viral, and parasitic outbreaks in humans, including "E. coli" and "Salmonella".## Taxonomy and etymology."Lactuca sativa" is a member of the "Lactuca" (lettuce) genus and the Asteraceae (sunflower or aster) family. The species was first described in 1753 by Carl Linnaeus in the second volume of his "Species Plantarum". Synonyms for "L. sativa.

Lettuce. include "Lactuca scariola" "sativa", "L. scariola" "integrata" and "L. scariola" "integrifolia". "L. scariola" is itself a synonym for "L. serriola", the common wild or prickly lettuce. "L. sativa" also has many identified taxonomic groups, subspecies and varieties, which delineate the various cultivar groups of domesticated lettuce. Lettuce is closely related to several "Lactuca" species from southwest Asia; the closest relationship is to "L. serriola", an aggressive weed common in temperate and subtropical zones in much of the world.The Romans referred to lettuce as ( meaning "dairy" in Latin), an allusion to the white substance, latex, exuded by cut stems. The.

Lettuce. name "Lactuca" has become the genus name, while (meaning "sown" or "cultivated") was added to create the species name. The current word "lettuce", originally from Middle English, came from the Old French or , which derived from the Roman name. The name "romaine" came from the variety of lettuce grown in the Roman papal gardens, while "cos", another term for romaine lettuce, came from the earliest European seeds of the type from the Greek island of Kos, a center of lettuce farming in the Byzantine period.## Description.Lettuce's native range spreads from the Mediterranean to Siberia, although it has been transported.

Lettuce. cannot be successfully frozen, canned or dried and must be eaten fresh. In spite of its high water content, traditionally grown lettuce has a low water footprint, with 237 liters of water required for each kilogram of lettuce produced. Hydroponic growing methods can reduce this water consumption by nearly two orders of magnitude.Lettuce varieties will cross with each other, making spacing of 1.5 to 6 (m) between varieties necessary to prevent contamination when saving seeds. Lettuce will also cross with "Lactuca serriola" (wild lettuce), with the resulting seeds often producing a plant with tough, bitter leaves. Celtuce, a lettuce variety.

Lettuce. grown primarily in Asia for its stems, crosses easily with lettuces grown for their leaves. This propensity for crossing, however, has led to breeding programs using closely related species in "Lactuca", such as "L. serriola", "L. saligna", and "L. virosa", to broaden the available gene pool. Starting in the 1990s, such programs began to include more distantly related species such as "L. tatarica".Seeds keep best when stored in cool conditions, and, unless stored cryogenically, remain viable the longest when stored at -20 (C); they are relatively short lived in storage. At room temperature, lettuce seeds remain viable for only a.

Lettuce. insects and disease and can make harvesting more difficult. Herbicides are often used to control weeds in commercial production. However, this has led to the development of herbicide-resistant weeds in lettuce cultivation.## Production.In 2020, world production of lettuce (report combined with chicory) was 28 million tonnes, with China alone producing 14.3 million tonnes or 52% of the world total (see table).Lettuce is the only member of the genus "Lactuca" to be grown commercially. Although China is the top world producer of lettuce, the majority of the crop is consumed domestically. Spain is the world's largest exporter of lettuce, with the.

Lettuce. lactucarium or "lettuce opium". Although the standard definition of lactucarium requires its production from "Lactuca virosa" or "wild lettuce", it was recognized that smaller quantities of lactucarium could be produced in a similar way from "Lactuca sativa" and "Lactuca canadensis" var. "elongata", and that lettuce-opium obtained from "Lactuca serriola" or "Lactuca quercina" was of superior quality.Romaine lettuce is one of the symbolic items on the Jewish Passover Seder plate as a bitter herb (maror).Some American settlers claimed that smallpox could be prevented through the ingestion of lettuce, and an Iranian belief suggested consumption of the seeds when afflicted with typhoid.

Strophostyles helvola. Strophostyles helvola, commonly called amberique-bean, annual sand bean, or trailing fuzzybean is a species of flowering plant in the legume family. It is native to eastern Canada and the eastern United States.## Description.It is an annual to perennial herbaceous vine, up to 3 m long, with light pubescence on the stem, leaves, and pods. The trifoliate leaves are often divided into three lobes, in a fiddle-shape (panduriform). They possess unique pea-like pink-purple flowers (fading to cream-yellow), with a gradually curving keel petal (the keel petal is one of the most distinguishing characters among the species of the genus). The fruit.

Strophostyles helvola. of "S. helvola" is up to 10 cm long, containing shiny black seeds with hairy coats originating from the inner surface of the pods. This seed coating lends the seeds buoyancy in water, which is thought to have contributed to its dispersal along major aquatic routes."Strophostyles helvola" is primarily diagnosed by its keel petal (prominent, thin, curving away from the banner at the distal end); long, cylindrical pods; and highly lobed leaves (though not always lobed, and "Strophostyles umbellata" may also show lobing).When the seed pods are mature, they burst open to release the seeds.## Taxonomy.In addition to the type,.

Strophostyles helvola. at least one infraspecific taxon has been recognized, "S. helvola" var. "missouriensis" (S. Watson) Britton, although there is little evidence for distinct varieties of this species.A widely used orthographic variant is "Strophostyles helvula", although only the former is taxonomically accepted.## Agricultural relevance."Strophostyles helvola" is a wild relative of the cultivated common bean ("Phaseolus vulgaris"), and could serve as an important model for understanding how herbaceous legumes adapt to different stressful environments. Specifically, "S. helvola" has coastal populations which show high salinity tolerance due to up-regulated genes.## Distribution and habitat.It is native to eastern Canada and the eastern United States.

Peking duck. Peking duck is a dish from Beijing (Peking) that has been prepared since the Imperial era. The meat is characterized by its thin, crispy skin, with authentic versions of the dish serving mostly the skin and little meat, sliced in front of the diners by the cook. Ducks bred especially for the dish are slaughtered after 65 days and seasoned before being roasted in a closed or hung oven. The meat is often eaten with spring onion, cucumber and sweet bean sauce with pancakes rolled around the fillings. Sometimes pickled radish is also inside. Crispy aromatic duck is a similar.

Peking duck. dish to Peking duck and is popular in the United Kingdom.## History.Duck has been roasted in China since the Southern and Northern Dynasties. A variation of roast duck was prepared for the Emperor of China in the Yuan Dynasty. The dish, originally named "shāo yāzi" (燒鴨子), was mentioned in the "Complete Recipes for Dishes and Beverages" (飲膳正要) manual in 1330 by Hu Sihui (忽思慧), an inspector of the imperial kitchen. The Peking roast duck that came to be associated with the term was fully developed during the later Ming Dynasty, and by then, Peking duck was one of the main.

Peking duck. dishes on imperial court menus. The first restaurant specialising in Peking duck, Bianyifang, was established in the Xianyukou, close to Qianmen of Beijing in 1416.By the Qianlong Period (1736–1796) of the Qing Dynasty, the popularity of Peking duck spread to the upper classes, inspiring poetry from poets and scholars who enjoyed the dish. For instance, one verse of "Dūmén zhúzhīcí", a Beijing local poem was, "Fill your plates with roast duck and suckling pig".In 1864, the Quanjude (全聚德) restaurant was established in Beijing. Yang Quanren (楊全仁), the founder of Quanjude, developed the hung oven to roast ducks.By the mid-20th century,.

Peking duck. Peking duck had become a national symbol of China, favored by tourists and diplomats alike. For example, Henry Kissinger, the Secretary of State of the United States, met Premier Zhou Enlai in the Great Hall of the People on 10 July 1971, during his first (secret) visit to China. After a round of inconclusive talks in the morning, the delegation was served Peking duck for lunch, which became Kissinger's favourite. The Americans and Chinese issued a joint statement the following day, inviting President Richard Nixon to visit China in 1972. Following Zhou's death in 1976, Kissinger paid another visit to.

Peking duck. Beijing to savor Peking duck. Peking duck, at the Quanjude in particular, has also been a favorite dish for various political leaders ranging from Cuban Fidel Castro to former German chancellor Helmut Kohl.Two notable restaurants in Beijing which serve this dish are Quanjude and Bianyifang, both centuries-old establishments which have become household names, each with their own style: Quanjude is known for using the hung oven roasting method, while Bianyifang uses the oldest technique of closed oven roasting.## Preparation.## Raising the duck.The ducks used to prepare Peking duck originated in Nanjing. They were large, had black feathers, and lived in.

Peking duck. the canals that linked the city to major waterways.With the relocation of the Chinese capital to Beijing, supply barge traffic increased in that area. Often these barges spilled water into side-canals, providing a habitat for the ducks. By the time of adoption of five-spice powder, a new breed of duck had been domesticated by Chinese farmers. Nowadays, Peking duck is prepared from the American Pekin duck ("Anas platyrhynchos domestica").Newborn ducks are raised in a free range environment for the first 45 days of their lives, and force fed 4 times a day for the next 15–20 days, resulting in ducks.

Peking duck. that weigh 5–7 kg (11–15 lbs). The force feeding of the ducks led to an alternate name for the animal, "Peking "stuffed" duck" ().## Cooking the duck.Fattened ducks are killed, plucked, eviscerated and rinsed thoroughly with water. Air is pumped under the skin through the neck cavity to separate the skin from the fat. The duck is then blanched in boiling hot water for two to three minutes before it is hung up to dry. This tightens the skin. While it is hung, the duck is glazed with a layer of runny syrup, and the inside is rinsed once more.

Peking duck. with water. A second layer of glaze/marinade of soy sauce, five-spice powder, and more maltose is then applied inside and out, and the duck is left to stand for 24 hours in a cool, dry place (or a refrigerator). It is then roasted in an oven until the skin turns shiny brown.Besides two traditional methods to prepare Peking duck, recipes have been compiled by chefs around the world to produce the dish at home.## Closed-oven style.Peking duck is originally roasted in a closed oven (), and Bianyifang is the restaurant that keeps this tradition. The closed oven is built of.

Peking duck. brick and fitted with metal griddles (). The oven is preheated by burning Gaoliang sorghum straw () at the base. The duck is placed in the oven immediately after the fire burns out, allowing the meat to be slowly cooked through the convection of heat within the oven. Controlling the fuel and the temperature is the main skill. In closed-oven style, duck meat is combined well with the fat under the skin, and therefore is juicy and tender.## Open-oven style.The open oven () was developed in the imperial kitchens during the Qing Dynasty, and adopted by the Quanjude restaurant chain.

Peking duck. It is designed to roast up to 20 ducks at the same time with an open fire fueled by hardwood from peach or pear trees. The ducks are hung on hooks above the fire and roasted at a temperature of 270 °C (525 °F) for 30–40 minutes. While the ducks are roasting, the chef may use a pole to dangle each duck closer to the fire for 30-second intervals. In open-oven style, the fat is usually melted during the cooking process, so the skin is crispy.## Serving.Peking duck is traditionally carved in front of the guests and served in three.

Peking duck. stages. First, slices of duck skin are served with sugar and sweet bean sauce as a dip. Duck skin is best enjoyed hot and crisp to the bite. The meat is then served with steamed pancakes () and an assortment of vegetable dishes, typically julienned cucumber and spring onion. Traditionally, diners dip slices of duck into the condiments and wrap into the pancake with cucumber and any other ingredients. The wrap is then eaten by hand or with chopsticks. The carved duck (鸭架) – the remainder of the roast duck, with choice cuts removed – can be cooked in three.

Peking duck. ways. The traditional way is in a broth with ingredients such as Chinese cabbage and soft tofu. The carved duck can also be chopped and stir-fried in sweet bean sauce, or rapidly sautéed and served with salt and pepper (椒鹽). Otherwise, the carved duck is packed to be taken home by the customers.## Reheating.Whole Peking ducks can be ordered as takeaway. The ducks can be reheated at home with an oven or stove. When an oven is used, the duck is heated at a temperature of 150 °C (300 °F) for 20 minutes, and then at 160 °C (325 °F).

Peking duck. for another 10 minutes. The stove method involves submerging the duck in boiling water before placing it on a griddle 70 cm (28 in) above the cooking fire. The water is replaced every 3–4 minutes until the duck is piping hot. To reheat the Peking duck with oil, the duck is sliced into thin pieces and placed in a strainer held over a wok of hot oil. The duck is then rinsed several times with the oil.## Notable restaurants.A number of restaurants in Beijing specialise in Peking duck. Examples include Quanjude, Bianyifang, Changan Yihao (長安一號), Dayali, Beijing Xiaowangfu (北京小王府) and.

Peking duck. Dadong Kaoyadian (大董烤鴨店).

It is very popular in the United Kingdom, where it was created in the latter half of the twentieth century.The duck is first marinated with spices, then steamed until tender, and finally deep fried until crispy. The meat has less fat and is drier and crispier compared to that of Peking duck. Crispy aromatic duck can also be seen in the United States, usually served with buns rather than pancakes.In Germany, some Asian fusion restaurants also serve crispy aromatic duck ("Knusprige.

Eurasian curlew. The Eurasian curlew or common curlew (Numenius arquata) is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across temperate Europe and Asia. In Europe, this species is often referred to just as the "curlew", and in Scotland known as the "whaup" in Scots.## Taxonomy.The Eurasian curlew was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his "Systema Naturae" under the binomial name "Scolopax arquata". It is now placed with eight other curlews in the genus "Numenius" that was introduced by the French ornithologist.

Eurasian curlew. Mathurin Jacques Brisson in 1760. The genus name "Numenius" is from Ancient Greek νουμήνιος, "noumēnios", a bird mentioned by Hesychius. It is associated with the curlew because it appears to be derived from "neos", "new" and "mene" "moon", referring to the crescent-shaped bill. The species name "arquata" is the Medieval Latin name for this bird, derived from Latin "arcuatus", "bow-shaped", and again referring to the shape of the bill.The English name "curlew" is imitative of the Eurasian curlew's call, but may have been influenced by the Old French "corliu", "messenger", from "courir ", "to run". It was first recorded in.

It is generally not possible to recognize the sex of a single Eurasian curlew, or even several ones, as there is much variation; telling male and female of a mated pair apart is usually possible however. The familiar call is a loud "curloo-oo".The only similar species over most of the curlew's range is the Eurasian whimbrel ("Numenius phaeopus"). The whimbrel is smaller and has a shorter bill with a kink rather than a smooth curve. Flying curlews may also resemble.

Heat engine. expressed in absolute temperature.The efficiency of various heat engines proposed or used today has a large range:3% (97 percent waste heat using low quality heat) for the ocean thermal energy conversion (OTEC) ocean power proposal25% for most automotive gasoline engines49% for a supercritical coal-fired power station such as the Avedøre Power Station60% for a combined cycle gas turbineThe efficiency of these processes is roughly proportional to the temperature drop across them. Significant energy may be consumed by auxiliary equipment, such as pumps, which effectively reduces efficiency.## Examples.It is important to note that although some cycles have a typical combustion location.

Heat engine. the simple conversion of work into heat (either through friction or electrical resistance). Refrigerators remove heat from within a thermally sealed chamber at low temperature and vent waste heat at a higher temperature to the environment and heat pumps take heat from the low temperature environment and 'vent' it into a thermally sealed chamber (a house) at higher temperature.In general heat engines exploit the thermal properties associated with the expansion and compression of gases according to the gas laws or the properties associated with phase changes between gas and liquid states.## Earth's heat engine.Earth's atmosphere and hydrosphere—Earth's heat engine—are coupled.

Gardener. A gardener is someone who practices gardening, either professionally or as a hobby.## Description.A gardener is any person involved in gardening, arguably the oldest occupation, from the hobbyist in a residential garden, the home-owner supplementing the family food with a small vegetable garden or orchard, to an employee in a plant nursery or the head gardener in a large estate.## Garden design and maintenance.The garden designer is someone who will design the garden, and the gardener is the person who will undertake the work to produce the desired outcome.## Design.The term gardener is also used to describe garden designers and.

Gardener. landscape architects, who are involved chiefly in the design of gardens, rather than the practical aspects of horticulture. Garden design is considered to be an art in most cultures, distinguished from gardening, which generally means "garden maintenance". Vita Sackville-West, Gertrude Jekyll and William Robinson were garden designers as well as gardeners.Garden design is the creation of a plan for the construction of a garden, in a design process. The product is the garden, and the garden designers attempt to optimize the given general conditions of the soil, location and climate, ecological, and geological conditions and processes to choose the right.

Cerioporus squamosus. Cerioporus squamosus aka "Polyporus squamosus" is a basidiomycete bracket fungus, with common names including dryad's saddle and pheasant's back mushroom. It has a widespread distribution, being found in North America, Australia, Asia, and Europe, where it causes a white rot in the heartwood of living and dead hardwood trees. The name "dryad's saddle" refers to creatures in Greek mythology called dryads who could conceivably fit and ride on this mushroom, whereas the "pheasant's back" analogy derives from the pattern of colors on the bracket matching that of a pheasant's back.## Etymology."Squamosus" comes from the Latin "squamosus" meaning covered with scales.

Cerioporus squamosus. or scaly, referring to the signature dark brown scales found on the mushroom's cap.## Taxonomy.The species was first described scientifically by British botanist William Hudson in 1778, who named it "Boletus squamosus". It was given its current name in 1886 by Quélet but is still widely known by the Friesian name "Polyporus squamosus".## Description.Dryad's Saddle is an annual mushroom commonly found attached to dead logs and stumps or on living hardwood trees at one point with a thick stem. Generally, the fruit body is round and between 8 – 30 (cm) across and up to 10 (cm) thick. The body.

Cerioporus squamosus. can be yellow to brown and has "squamules" or scales on its upper side. On the underside one can see the pores that are characteristic of the genus "Cerioporus"; they are made up of tubes packed together closely. The tubes are between 1 and 12 (mm) long. The stalk is thick and short, up to 5 (cm) long. The fruit body will produce a white spore print if laid onto a sheet of paper. The spores are 11-15 x 4-5 µm and are long and smooth ellipsoids. They can be found alone, in clusters of two or three, or forming.

Cerioporus squamosus. made from this and many other mushrooms of the genus "Cerioporus". The mushroom's smell resembles watermelon rind. "Polyporus squamosus" has a mild nutty flavour.

This form has Coxeter diagram and Schläfli symbol h{4,3}. The tetrahedron in this case has edge length 2. Inverting these coordinates generates the dual tetrahedron, and the pair together form the stellated octahedron, whose vertices are.

Tetrahedron. two tetrahedra in the cube). The symmetries of a regular tetrahedron correspond to half of those of a cube: those that map the tetrahedra to themselves, and not to each other.The tetrahedron is the only Platonic solid that is not mapped to itself by point inversion.The regular tetrahedron has 24 isometries, forming the symmetry group Td, [3,3], (*332), isomorphic to the symmetric group, "S"4.

Tetrahedron. are projected as circular arcs on the plane.## Helical stacking.Regular tetrahedra can be stacked face-to-face in a chiral aperiodic chain called the Boerdijk–Coxeter helix. In four dimensions, all the convex regular 4-polytopes with tetrahedral cells (the 5-cell, 16-cell and 600-cell) can be constructed as tilings of the 3-sphere by these chains, which become periodic in the three-dimensional space of the 4-polytope's boundary surface.## Irregular tetrahedra.Tetrahedra which do not have four equilateral faces are categorized and named by the symmetries they do possess.If all three pairs of opposite edges of a tetrahedron are perpendicular, then it is called an orthocentric tetrahedron.

Tetrahedron. to the opposite faces are inversely proportional to the areas of these faces.For a tetrahedron with vertices,, and, the volume is , or any other combination of pairs of vertices that form a simply connected graph. This can be rewritten using a dot product and a cross product, yieldingformula_9If the origin of the coordinate system is chosen to coincide with vertex d, then d = 0, soformula_10where a, b, and c represent three edges that meet at one vertex, and is a scalar triple product. Comparing this formula with that used to compute the volume of a parallelepiped, we conclude.

A negative value of the determinant means that a tetrahedron cannot be constructed with the given distances.

Tetrahedron. segment joining the midpoints of two opposite edges is called a "bimedian" of the tetrahedron. Hence there are four medians and three bimedians in a tetrahedron. These seven line segments are all concurrent at a point called the "centroid" of the tetrahedron. In addition the four medians are divided in a 3:1 ratio by the centroid (see Commandino's theorem). The centroid of a tetrahedron is the midpoint between its Monge point and circumcenter. These points define the "Euler line" of the tetrahedron that is analogous to the Euler line of a triangle.The nine-point circle of the general triangle has an.

Tetrahedron. is a diagonal of one of the cube's faces. For one such embedding, the Cartesian coordinates of the vertices are(+1, +1, +1);(−1, −1, +1);(−1, +1, −1);(+1, −1, −1).This yields a tetrahedron with edge-length 2, centered at the origin. For the other tetrahedron (which is dual to the first), reverse all the signs. These two tetrahedra's vertices combined are the vertices of a cube, demonstrating that the regular tetrahedron is the 3-demicube.The volume of this tetrahedron is one-third the volume of the cube. Combining both tetrahedra gives a regular polyhedral compound called the compound of two tetrahedra or stella octangula.The interior.

Tetrahedron. of the stella octangula is an octahedron, and correspondingly, a regular octahedron is the result of cutting off, from a regular tetrahedron, four regular tetrahedra of half the linear size (i.e., rectifying the tetrahedron).The above embedding divides the cube into five tetrahedra, one of which is regular. In fact, five is the minimum number of tetrahedra required to compose a cube. To see this, starting from a base tetrahedron with 4 vertices, each added tetrahedra adds at most 1 new vertex, so at least 4 more must be added to make a cube, which has 8 vertices.Inscribing tetrahedra inside the.

What condition on 12 angles is necessary and sufficient for.

Tetrahedron. them to be the 12 angles of some tetrahedron? Clearly the sum of the angles of any side of the tetrahedron must be 180°. Since there are four such triangles, there are four such constraints on sums of angles, and the number of degrees of freedom is thereby reduced from 12 to 8. The four relations given by this sine law further reduce the number of degrees of freedom, from 8 down to not 4 but 5, since the fourth constraint is not independent of the first three. Thus the space of all shapes of tetrahedra is 5-dimensional.## Law of.
