Spectrophotometer
A spectrophotometer measures either the amount of light reflected from a sample object or the amount of light that is absorbed by the sample object. Spectrophotometry is the quantity based study of electromagnetic spectra.
In short, the sequence of events in a modern spectrophotometer is as follows:
There are two kinds of spectrophotometers: single beam and double beam. A double beam spectrophotometer compares the light intensity between two light paths. One path containing a reference sample, the other holding the test sample. A single beam spectrophotometer measures the relative light intensity of the beam before and after a test sample is inserted. A double beam machine makes comparison readings easier and more stable. But a single beam machine can have measure a wider range of light frequencies. Single beam machines have simple optical systems and are more compact. When the spectrophotometer is built into another device (like microscopes or telescopes) only single beam machines will work.
Many older spectrophotometers must be calibrated by a procedure known as "zeroing." The absorbancy of a reference substance is set as a baseline value, so the absorbancies of all other substances are recorded relative to the initial "zeroed" substance. The spectrophotometer then displays % absorbancy (the amount of light absorbed relative to the initial substance).
Spectrophotometers can also measure luminescence. For example, the machine can shine ultraviolet light of one frequency on the sample. This will excite the sample and make it glow. The detectors can then measure the light glowing from the sample at a different frequency.
Russian Orthodox Church
The Russian Orthodox Church of the Moscow Patriarchate are Christians who are united under the Patriarch of Moscow, who in turn is in communion with the other patriarchs and primates of the Eastern Orthodox Church.
Form
Form (Lat. "forma" Eng. "mould"), refers to the external three-dimensional outline, appearance or configuration of some thing - in contrast to the matter or content or substance of which it is mainly composed (compare with shape).
Martiros Saryan
Martiros Saryan (, February 28, 1880 – 5 May 1972 ) was a Russian-born Armenian painter.
He was born into an Armenian family in Nor Nakhijevan (now part of Russia). In 1895, he was 15, he finished the Nakhichevan school and from 1897 to 1904 learned at the Moscow School of Arts, also in the workshops of Valentin Serov and Konstantin Korovin. He was heavily influenced by the work of Paul Gauguin and Henri Matisse. He showed his works in various shows.
"Nature's ways are wonderful and unfathomable. The grain swells in the soil, the sprout grows and flowers when the time comes and then it bears new fruit and so does not die. We are like grain. We never die because we are One with Nature. To understand this is to comprehend Immortality--the Apotheosis of the Human Race. It is with this conviction that I have lived my Life. My Life is a store of my experience, a Life of aspirations, sorrows, joys and triumphs." (M. Saryan)
Library of Congress
The Library of Congress is the "de facto" national library of the United States and the research arm of the United States Congress.
The head of the Library is the Librarian of Congress Carla Hayden.
WHAT IS IT?
The primary function of the Library of Congress is to serve the Congress. ... The Library welcomes public use of its general reference facilities and endeavors to offer the widest possible use of its collections consistent with their preservation and with its obligation to serve the Congress and other government agencies.The Library of Congress is the largest library in the world, with millions of books, recordings, photographs, newspapers, maps and manuscripts in its collections. The Library is the main research arm of the U.S. Congress and the home of the U.S.Copyright Office.Libraries are important cornerstones of a healthy community. ... College students often use the library when they are home for the weekend or for holidays. And the reference resources in public libraries are usually unavailable elsewhere in the community. The library is a unique and valuable resource.
Forest, Ontario
Forest, Ontario is a town in Lambton County, Ontario, Canada. About 3,000 people live in the town. It the biggest town in Lambton Shores. The town was an important lumber town. It even had its own train stop. Forest is now a tourist attraction. It has trails and camp facilities.
Forest is located on land that was once dense forest. When the Grand Trunk Railway was built, the station for the town was named for the dense forest. In 1859, the first post office was then named Forest.
The industry of the town was first based on the large amount of fruit growing in the area. There was once a canning factory and a basket factory in Forest. In more recent years, the town has become a dormitory community for the city of Sarnia and, to a lesser extent, London, Ontario. The large tourism area along the shores of nearby Lake Huron also helps local businesses. Several small manufacturing plants supporting the automobile industry have also opened in the past few years.
In 2001, the last year that Forest was a national census unit, the town had a population of 2,857. The average age of the people who live in Forest was about 42. This is five years older than the average for the entire province. The average earnings of the people living in Forest was $27,902 (CAD) in the year 2000. In 2006, the local census unit was changed to the town of Lambton Shores. Information for Forest itself is not available.
Forest has a high school, North Lambton Secondary School. The school has a large gymnasium and cafeteria. It also has access to washroom and meal preparation facilities. Forest has two separate school systems. It has a public school system, Kinnwood Central Public School, and a private school system, St. John Fisher. Both systems have elementary schools.
There are many recreational facilities in the town. These include an enclosed arena/community center with baseball and soccer fields, a lawn bowling club and public tennis courts.
