A Prairie Home Companion

A Prairie Home Companion is a live radio variety show created and hosted by Garrison Keillor. The show runs on Saturdays from 5 to 7 p.m. Central Time, and usually originates from the Fitzgerald Theater in Saint Paul, Minnesota, although it is frequently taken on the road. A Prairie Home Companion is known for its musical guests, especially folk and traditional musicians, tongue-in-cheek radio drama, and Keillor's storytelling segment, "News from Lake Wobegon".

It is produced by Prairie Home Productions and distributed by American Public Media, and is most often heard on public radio stations in the United States. The show has a long history, existing in a similar form as far back as 1974, and borrowing the name from a radio program in existence in 1969. It was named after the Prairie Home Cemetery in Moorhead, Minnesota, next to Concordia College.

The radio program inspired a 2006 film of the same name, directed by Robert Altman and featuring Keillor, Lily Tomlin, Meryl Streep, Lindsay Lohan, Tommy Lee Jones, Kevin Kline, John C. Reilly, and Woody Harrelson.

## History

The earliest radio program to have this name bears little resemblance to what is currently heard on Saturday evenings. A Prairie Home Companion was originally a morning show running from 6 to 9 a.m. on Minnesota Public Radio.

After researching the Grand Ole Opry for an article, Keillor became interested in doing a variety show on the radio. On July 6, 1974, the first live broadcast of A Prairie Home Companion took place. That show was broadcast from St. Paul in the Janet Wallace Auditorium of Macalester College. Twelve audience members turned out, mostly children. The second episode featured the first performance on the show by Butch Thompson, who became house pianist. Thompson stayed with the program until 1986, and still frequently performs on the show.

In 1978, the show moved into the World Theater in St. Paul, which was renovated in 1986 and renamed the Fitzgerald Theater in 1994. This is the same location that the program uses today.

The show went off the air in 1987, and Keillor married and spent some time abroad during the following two years. For a brief time, the show was replacedâ€”both on the air and in the World Theaterâ€”by Good Evening, a live variety show designed by ex-Prairie Home andAll Things Consideredstaffers to retain the audience Keillor cultivated over the years. Many stations opted instead to continue APHC repeats in its traditional Saturday time slot.

In 1989, Keillor returned to radio with The American Radio Company of the Air (renamed Garrison Keillor's American Radio Company in its second season), broadcast originally from the Brooklyn Academy of Music. The new program was a slightly revised format, with sketches and musical guests reflecting a more New York sensibility, rather than the country and folk music predominant in APHC. Also, while Keillor still sang and delivered a regular monologue on American Radio Company, Lake Wobegon was initially downplayed, as he felt it was "cruel" to talk to a Brooklyn audience about life in a small town. During this period, Keillor revived the full APHC format only for "annual farewell performances". In the fall of 1992, Keillor returned to the World Theater with ARC for the majority of the season, and the next year, the program officially reverted to the A Prairie Home Companion name and format.

While many of the episodes originate from St. Paul, the show often travels to other cities around the U.S. and overseas for its live weekly broadcasts. Common road venues include The Town Hall in New York City, Tanglewood in Lenox, Massachusetts, Wolf Trap in Vienna, Virginia, Ryman Auditorium in Nashville, Tennessee, the Greek Theater in Los Angeles, and the State Theater in Minneapolis. There is also a show each year at the Minnesota State Fair.

The show was originally distributed nationally by Minnesota Public Radio in association with Public Radio International. Its current distributor is Minnesota Public Radio's distribution unit, American Public Media.

## Format

Each show opens with the Spencer Williams composition "Tishomingo Blues" as the theme song, but with lyrics written especially for A Prairie Home Companion. Before 1987, the show's theme song was the paper that is printed with fine lines making up a regular grid. The lines are often used as guides for plotting mathematical functions or experimental data and drawing diagrams. It is commonly found in mathematics and engineering education settings and in laboratory notebooks.

## Format and availability of graph paper

Graph paper is available either as loose leaf paper or bound in notebooks. It is becoming less common as computer software such as spreadsheets and plotting programs has supplanted many of the former uses of graph paper. Some users of graph paper now print pdf images of the grid pattern as needed rather than buying it pre-printed.

## Types of graph paper

• Quad paper is a common form of graph paper with a sparse grid printed in light blue or gray and right to the edge of the paper. This is often four squares to the inch for work not needing too much detail. It is sometimes referred to as quadrille paper.
• Engineering paper is traditionally printed on light green or tan translucent paper. The grid lines are printed on the back side of each page and show through faintly to the front side. Each page has an unprinted margin. When photocopied or scanned, the grid lines typically do not show up in the resulting copy, which often gives the work a neat, uncluttered appearance. In the US and Canada, some engineering professors require student homework to be completed on engineering paper.
• GenkÅ� yÅ�shi&mdash; A type of manuscript paper used in Japan, normally printed with 400 squares in two sets of 20 lines of 10, used for compositions written inhorizontal script.
• Hexagonal&mdash; This paper shows regular hexagons instead of squares. These can be used to map geometric tiled or tesselated designs among other uses
• Isometric graph paper or 3D graph paper&mdash; This type is a triangular graph paper which uses a series of three guidelines forming a 60Â° grid of small triangles. The triangles are arranged in groups of six to make hexagons. The name suggests the use for isometric views or pseudo-three dimensional views. Among other functions, they can be used in the design of trianglepointembroidery.
• Logarithmic&mdash; This type of paper has rectangles drawn in varying widths corresponding to an logarithmic scales for semilog graphs or log-log graphs.
• Normalprobability paper &mdash; This type is another graph paper with rectangles of variable widths. It is designed so that "the graph of the normal distribution function is represented on it by a straight line".[http://eom.springer.de/P/p074910.htm]
• Polar Coordinate&mdash; This type of paper has concentric circles divided into small arcs or 'pie wedges' to allow plotting in polar coordinates.

In general, graphs showing grids are sometimes called Cartesian graphs because the square can be used to map measurements onto a Cartesian (x vs. y) coordinate system. It is also available without lines but with dots at the positions where the lines would intersect.

Ceramic Tile Ceramic Tile

Wall and floor tile used for interior and exterior decoration belongs to a class of ceramics known as whitewares. The production of tile dates back to ancient times and peoples, including the Egyptians, the Babylonians, and the Assyrians. For instance, the Step Pyramid for the Pharoah Djoser, built in ancient Egypt around 2600 b.c., contained colorful glazed tile. Later, ceramic tile was manufactured in virtually every major European country and in the United States. By the beginning of the twentieth century, tile was manufactured on an industrial scale. The invention of the tunnel kiln around 1910 increased the automation of tile manufacture. Today, tile manufacture is highly automated. The American National Standards Institute separates tiles into several classifications. Ceramic mosaic tile may be either porcelain or of natural clay composition of size less than 39 cm2 (6 in.2). Decorative wall tile is glazed tile with a thin body used for interior decoration of residential walls. Paver tile is glazed or unglazed porcelain or natural clay tile of size 39 cm2 (6 in.2) or more. Porcelain tile is ceramic mosaic tile or paver tile that is made by a certain method called dry pressing. Quarry tile is glazed or unglazed tile of the same size as paver tile, but made by a different forming method. Europe, Latin America, and the Far East are the largest producers of tile, with Italy the leader at 16.6 million ft.2/day as of 1989. Following Italy (at 24.6 percent of the world market) are Spain (12.6 percent), Brazil and Germany (both at 11.2 percent), and the United States (4.5 percent). The total market for floor and wall tile in 1990 according to one estimate was $2.4 billion. The United States has approximately 100 plants that manufacture ceramic tile, which shipped about 507 million ft.2 in 1990 according to the U.S. Department of Commerce. U.S. imports, by volume, accounted for approximately 60 percent of consumption in 1990, valued at around$500 million. Italy accounts for almost half of all imports, with Mexico and Spain following. U.S. exports have seen some growth, from $12 million in 1988 to about$20 million in 1990. Because the tile industry is a relatively mature market and dependent on the building industry, growth will be slow. The United States Department of Commerce estimates a three to four percent increase in tile consumption over the next five years. Another economic analysis predicts that 494 million ft.2 will be shipped in 1992, a growth of about 4 percent from the previous year. Some tile manufacturers are a bit more optimistic; an American Ceramic Society survey showed an average growth of around 36 percent per manufacturer over the next five years. The raw materials used to form tile consist of clay minerals mined from the earth's crust, natural minerals such as feldspar that are used to lower the firing temperature, and chemical additives required for the shaping process. The minerals are often refined or beneficiated near the mine before shipment to the ceramic plant. The raw materials must be pulverized and classified according to particle size. Primary crushers are used to reduce large lumps of material. Either a jaw crusher or gyratory crusher is used, which operate using a horizontal squeezing motion between steel plates or rotating motion between steel cones, respectively. Secondary crushing reduces smaller lumps to particles. Hammer or muller mills are often used. A muller mill uses steel wheels in a shallow rotating pan, while a hammer mill uses rapidly moving steel hammers to crush the material. Roller or cone type crushers can also be used. A third particle size reduction step may be necessary. Tumbling types of mills are used in combination with grinding media. One of the most common types of such mills is the ball mill, which consists of large rotating cylinders partially filled with spherical grinding media. Screens are used to separate out particles in a specific size range. They operate in a sloped position and are vibrated mechanically or electromechanically to improve material flow. Screens are classified according to mesh number, which is the number of openings per lineal inch of screen surface. The higher the mesh number, the smaller the opening size. A glaze is a glass material designed to melt onto the surface of the tile during firing, and which then adheres to the tile surface during cooling. Glazes are used to provide moisture resistance and decoration, as they can be colored or can produce special textures. Once the raw materials are processed, a number of steps take place to obtain the finished product. These steps include batching, mixing and grinding, spray-drying, forming, drying, glazing, and firing. Many of these steps are now accomplished using automated equipment. A variety of pollutants are generated during the various manufacturing steps; these emissions must be controlled to meet air control standards. Among the pollutants produced in tile manufacture are fluorine and lead compounds, which are produced during firing and glazing. Lead compounds have been significantly reduced with the recent development of no-lead or low-lead glazes. Fluorine emissions can be controlled with scrubbers, devices that basically spray the gases with water to remove harmful pollutants. They can also be controlled with dry processes, such as fabric filters coated with lime. This lime can then be recycled as a raw material for future tile. The tile industry is also developing processes to recycle wastewater and sludge produced during milling, glazing, and spray-drying. Already some plants recycle the excess powder generated during dry-pressing as well as the overspray produced during glazing. Waste glaze and rejected tile are also returned to the body preparation process for reuse. Most tile manufacturers now use statistical process control (SPC) for each step of the manufacturing process. Many also work closely with their raw material suppliers to ensure that specifications are met before the material is used. Statistical process control consists of charts that are used to monitor various processing parameters, such as particle size, milling time, drying temperature and time, compaction pressure, dimensions after pressing, density, firing temperature and time, and the like. These charts identify problems with equipment, out of spec conditions, and help to improve yields before the final product is finished. The final product must meet certain specifications regarding physical and chemical properties. These properties are determined by standard tests established by the American Society of Testing and Materials (ASTM). Properties measured include mechanical strength, abrasion resistance, chemical resistance, water absorption, dimensional stability, frost resistance, and linear coefficient of thermal expansion. More recently, the slip resistance, which can be determined by measuring the coefficient of friction, has become a concern. However, no standard has yet been established because other factors (such as proper floor design and care) can make results meaningless. In order to maintain market growth, tile manufacturers will concentrate on developing and promoting new tile products, including modular or cladding tile, larger-sized tile, slip- and abrasion-resistant tile, and tile with a polished, granite or marble finish. This is being accomplished through the development of different body formulations, new glazes, and glaze applications, and by new and improved processing equipment and techniques. Automation will continue to play an important role in an effort to increase production, lower costs, and improve quality. In addition, changes in production technology due to environmental and energy resource issues will continue. Bender, W. and F. Handle, eds.

Question:i want a comparitive data on air pollution of different cities of the world,means i want some sites where i can find comparitive tables,pie charts,bar graphs etc.

Answers:Try to see what you can find here or may be they can assist you: http://www.worldwatch.org/

Question:Please approach the answer in an essay form with an introduction and conclution seperately.

Question:hi, I have a question.the question asks: draw a bar chart to show the difference in composition between inhaled and exhaled air. how can I do this? thank you. I have already searched for it in google, but could not find anything

Answers:google it. EDIT: Okay,this may help. Exhaled air has a much higher percentage of CO2 compared to inhaled air; there is also a lower percentage of oxygen in exhaled air compared to inhaled air - but the difference is not so great as the body can only absorb a small amount of the oxygen which is in each lungful of air, so much of it gets breathed out again. CO2 content of the inhaled air is 0.04 %, whereas, of the exhaled air is 4 % (100 times) Humidity of the inhaled air is dependent on the geographical place. I didn't find a bar chart,but you can take help from this.
