United States Lighthouse Service
The United States Lighthouse Service, also known as the Bureau of Lighthouses, was the agency of the United States Government and the general lighthouse authority for the United States from the time of its creation in 1910 as the successor of the United States Lighthouse Board until 1939 when it was merged into the United States Coast Guard. It was responsible for the upkeep and maintenance of all lighthouses and lightvessels in the United States. History 1789–1910 In 1789, the United States Lighthouse Establishment (USLHE) was created and operated under the Department of the Treasury. All U.S. lighthouse ownership was transferred to the government which became the general lighthouse authority (GLA). In 1792, the Cape Henry Lighthouse was the first lighthouse built by the USLHE. In 1822, French physicist, Augustin Fresnel designed the Fresnel lens. In 1841 the Fresnel lens was first used in the United States and installed on the Navesink Lighthouse. In 1852 the Lighthou ...

United States Lighthouse Board
The United States Lighthouse Board was the second agency of the U.S. federal government, under the Department of Treasury, responsible for the construction and maintenance of all lighthouses and navigation aids in the United States, between 1852 and 1910. The new agency was created following complaints of the shipping industry of the previous administration of lighthouses under the Treasury's Lighthouse Establishment, which had had jurisdiction since 1791, and since 1820, been under the control of Stephen Pleasonton. The quasi-military board first met on April 28, 1851, and with its establishment, the administration of lighthouses and other aids to navigation would take their largest leap toward modernization since the inception of federal government control.Amy K. Marshall "Frequently Close to the Point of Peril: A History of Buoys and Tenders in U.S. Coastal Waters, 1789–1939'", A Master's Thesis In 1910, the Lighthouse Board was disestablished in favor of a more civilia ...

Colza Oil
Close-up of canola blooms Canola flower Rapeseed oil is one of the oldest known vegetable oils. There are both edible and industrial forms produced from rapeseed, the seed of several cultivars of the plant family Brassicaceae. Historically, it was restricted as a food oil due to its content of erucic acid. Laboratory studies about this acid have shown damage to the cardiac muscle of laboratory animals in high quantities. It also imparts a bitter taste, and glucosinolates, which made many parts of the plant less nutritious in animal feed. Rapeseed oil from standard cultivars can contain up to 54% erucic acid. Canola oil is a food-grade version derived from rapeseed cultivars specifically bred for low acid content. It is also known as low erucic acid rapeseed (LEAR) oil and is generally recognized as safe by the United States Food and Drug Administration.ecfr.gov version Canola oil is limited by government regulation to a maximum of 2% erucic acid by weight in the US and t ...

Diamond Shoal Lightship No
Diamond is a Allotropes of carbon, solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond is tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water. Another solid form of carbon known as graphite is the Chemical stability, chemically stable form of carbon at Standard temperature and pressure, room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest Scratch hardness, hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of lattice defect, defects or impurities (about one per million of lattice atoms) can color ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lightship Nantucket
The station named ''Nantucket'' or ''Nantucket Shoals'' was served by a number of lightvessels (also termed lightships) that marked the hazardous Nantucket Shoals south of Nantucket Island. The vessels, given numbers as their "name," had the station name painted on their hulls when assigned to the station. Several ships have been assigned to the Nantucket Shoals lightship station and have been called ''Nantucket''. It was common for a lightship to be reassigned and then have the new station name painted on the hull. The Nantucket station was a significant US lightship station for transatlantic crossing, transatlantic voyages. Established in 1854, the station marked the limits of the dangerous Nantucket Shoals. She was the last lightship seen by vessels departing the United States, as well as the first beacon seen on approach. The position was southeast of Nantucket Island, the farthest lightship in North America, and experienced clockwise rotary tidal currents. History Lightsh ...

Spanish–American War
The Spanish–American War (April 21 – August 13, 1898) was fought between Restoration (Spain), Spain and the United States in 1898. It began with the sinking of the USS Maine (1889), USS ''Maine'' in Havana Harbor in Cuba, and resulted in the U.S. acquiring sovereignty over Puerto Rico, Guam, and the Philippines, and establishing a protectorate over Cuba. It represented U.S. intervention in the Cuban War of Independence and Philippine Revolution, with the latter later leading to the Philippine–American War. The Spanish–American War brought an end to almost four centuries of Spanish presence in the Americas, Asia, and the Pacific; the United States meanwhile not only became a major world power, but also gained several island possessions spanning the globe, which provoked rancorous debate over the wisdom of expansionism. The 19th century represented a clear decline for the Spanish Empire, while the United States went from a newly founded country to a rising power. In 1895, C ...

Electricity
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the Work (physics), work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing w ...
