Incubators (egg)
An incubator is a device simulating avian incubation by keeping eggs warm at a particular temperature range and in the correct humidity with a turning mechanism to hatch them. The common names of the incubator in other terms include ''breeding / hatching machines'' or ''hatchers'', ''setters'', and ''egg breeding / equipment''. History The Egyptians had a method of incubating in 400 BC, using a cylindrical building or oven that had a fire at the bottom. The eggs that were incubating were placed on an inverted cone that was partially covered in ash. The eggs were placed in a woven basket that sat on top of the ashes. The building also had a roof that allowed smoke to escape, but it kept the rain out. Egyptian egg ovens are typically brick structures in a pyramidal shape, with two internal chambers. left, Réaumur's incubator Controlled scientific incubation required the accurate and repeatable measurement of temperature, such as the alcohol-based thermometer proposed by t ...

René Antoine Ferchault De Réaumur
René Antoine Ferchault de Réaumur (; 28 February 1683, La Rochelle – 17 October 1757, Saint-Julien-du-Terroux) was a French entomologist and writer who contributed to many different fields, especially the study of insects. He introduced the Réaumur temperature scale. Life Réaumur was born in a prominent La Rochelle family and educated in Paris. He learned philosophy in the Jesuits' college at Poitiers, and in 1699 went to Bourges to study civil law and mathematics under the charge of an uncle, canon of La Sainte-Chapelle. In 1703 he went to Paris, where he continued the study of mathematics and physics. In 1708, at the age of 24, he was nominated by Pierre Varignon (who taught him mathematics) and elected a member of the Académie des Sciences.Egerton, F.

Eggs
Humans and human ancestors have scavenged and eaten animal eggs for millions of years. Humans in Southeast Asia had domesticated chickens and harvested their eggs for food by 1,500 BCE. The most widely consumed eggs are those of fowl, especially chickens. Eggs of other birds, including ostriches and other ratites, are eaten regularly but much less commonly than those of chickens. People may also eat the eggs of reptiles, amphibians, and fish. Fish eggs consumed as food are known as roe or caviar. Bird and reptile eggs consist of a protective eggshell, albumen ( egg white), and vitellus ( egg yolk), contained within various thin membranes. Egg yolks and whole eggs store significant amounts of protein and choline, and are widely used in cookery. Due to their protein content, the United States Department of Agriculture formerly categorized eggs as ''Meats'' within the Food Guide Pyramid (now MyPlate). Despite the nutritional value of eggs, there are some potential health iss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gettysburg, Ohio
Gettysburg is a village in Darke County, Ohio, United States. The population was 513 at the 2010 census. History Gettysburg was founded by natives of Adams County, Pennsylvania, in the late 1820s. When the settlement was platted by John Hershey in 1842, the community was named for Gettysburg, the county seat of Adams County. The community's first church was a congregation of the Presbyterian Church in the United States of America, established in 1847 or 1848, while the first school was built in 1850. By the 1860s the village had an active business sector including general stores, shoe shops, cabinet makers, wagon/carriage shops, harness shops, tanning yards, cooperages, blacksmiths, tinning shop, tailors, physicians, a hotel, grain elevator, flouring and saw mills. Several saloons opened but soon failed. Around 1863 the Richmond and Covington Railroad (becoming part of the Pennsylvania Railroad in 1921) constructed a rail line that ran through Gettysburg.

French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV of France, Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Réaumur Scale
__NOTOC__ The Réaumur scale (; °Ré, °Re, °r), also known as the "octogesimal division", is a temperature scale for which the melting and boiling points of water are defined as 0 and 80 degrees respectively. The scale is named for René Antoine Ferchault de Réaumur, who first proposed a similar scale in 1730. Change in scale Réaumur's thermometer contained diluted alcohol (ethanol) and was constructed on the principle of using 0° for the melting temperature of water, and graduating the tube into degrees, each of which was one-thousandth of the volume contained by the bulb and tube up to the zero mark. He suggested that the concentration of alcohol employed be such that it began boiling at 80 °Ré – that is, when it had expanded in volume by 8%. He chose alcohol instead of mercury because it expands more visibly, but this posed problems: his original thermometers were very bulky, and the low boiling point of alcohol made them unsuitable for many applications.

Avian Incubation
Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg. Multiple and various factors are vital to the incubation of various species of animal. In many species of reptile for example, no fixed temperature is necessary, but the actual temperature determines the sex ratio of the offspring. In birds in contrast, the sex of offspring is genetically determined, but in many species a constant and particular temperature is necessary for successful incubation. Especially in poultry, the act of sitting on eggs to incubate them is called brooding. The action or behavioral tendency to sit on a clutch of eggs is also called broodiness, and most egg-laying breeds of poultry have had this behavior selectively bred out of them to increase production.

Penny Magazine
''The Penny Magazine'' was an illustrated British magazine aimed at the working class, published every Saturday from 31 March 1832 to 31 October 1845. Charles Knight created it for the Society for the Diffusion of Useful Knowledge in response to ''Chambers's Edinburgh Journal'', which started two months earlier. Sold for only a penny and illustrated with wood-engravings, it was an expensive enterprise that could only be supported by very large circulation. Though initially very successful—with a circulation of 200,000 in the first year—it proved too dry and too Whiggish to appeal to the working-class audience it needed to be financially viable. Its competitor—which included a weekly short story—grew more slowly, but lasted much longer. Early success During the first few years of publication ''The Penny Magazine'' was highly successful in building an audience selling over 200,000 copies in 1832 with an estimation of nearly one million readers that year and easily outsell ...

Society For The Diffusion Of Useful Knowledge
The Society for the Diffusion of Useful Knowledge (SDUK) was founded in London in 1826, mainly at the instigation of Whig MP Henry Brougham, with the object of publishing information to people who were unable to obtain formal teaching or who preferred self-education. It was a largely Whig organisation, and published inexpensive texts intended to adapt scientific and similarly high-minded material for the rapidly-expanding reading public over twenty years until it was disbanded in 1846. Origins Henry Brougham considered that mass education was an essential prerequisite for political reform. In October 1824 he contributed an article on "scientific education of the people" to the Whig ''Edinburgh Review'', in which he argued that popular education would be greatly enhanced by the encouragement of cheap publications to complement the numerous recently founded provincial mechanics' institutes. The following year a version of this article was issued as a pamphlet entitled ''Practi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
