Aquamog
An aquamog is a machine for removing weeds growing over a body of water. An aquamog was used in 2018 for removing water primrose from North Lake in San Francisco's Golden Gate Park. A newspaper photo shows a machine similar to a backhoe on very wide crawlers. Aquatic Environments, a Concord, California contractor, used an aquamog to scoop up muck at the Palace of Fine Arts lagoon, in a project expected to take 26 days. The name ''aquamog'' was derived from the multi-purpose vehicle ''Unimog'' produced by Mercedes-Benz Mercedes-Benz (), commonly referred to as Mercedes and sometimes as Benz, is a German luxury and commercial vehicle automotive brand established in 1926.

Water Primrose
''Ludwigia'' (primrose-willow, water-purslane, or water-primrose) is a genus of about 82 species of aquatic plants native to Central and South America with a cosmopolitan but mainly tropical distribution. At current, there is much debate among botanists and plant taxonomists as to the classification of many ''Ludwigia'' species. Botanists from the US Department of Agriculture are currently doing genetic analyses on plants from the Western US and South America to better classify members of this genus. The genus was named by Carl Linnaeus after Christian Gottlieb Ludwig (1709-1773), a German botanist, who was apparently not amused by this honour. Fossil record A large number of fossil seeds of †''Ludwigia collinsoniae'' and †''Ludwigia corneri'' have been described from middle Miocene strata of the Fasterholt area near Silkeborg in Central Jutland, Denmark. Selected species Listed from the NCBI The National Center for Biotechnology Information (NCBI) is part of the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Gate Park
Golden Gate Park, located in San Francisco, California, United States, is a large urban park consisting of of public grounds. It is administered by the San Francisco Recreation & Parks Department, which began in 1871 to oversee the development of Golden Gate Park. Configured as a rectangle, it is similar in shape to but 20 percent larger than Central Park in New York City, to which it is often compared. It is over three miles () long east to west, and about half a mile () north to south. With 24 million visitors annually, Golden Gate is the third most-visited city park in the United States after Central Park and the Lincoln Memorial. History Development In the 1860s, San Franciscans began to feel the need for a spacious public park similar to Central Park, which was then taking shape in New York City. Golden Gate Park was carved out of unpromising sand and shore dunes that were known as the Outside Lands, in an unincorporated area west of San Francisco's then-curren ...

San Francisco Chronicle
The ''San Francisco Chronicle'' is a newspaper serving primarily the San Francisco Bay Area of Northern California. It was founded in 1865 as ''The Daily Dramatic Chronicle'' by teenage brothers Charles de Young and Michael H. de Young. The paper is owned by the Hearst Corporation, which bought it from the de Young family in 2000. It is the only major daily paper covering the city and county of San Francisco. The paper benefited from the growth of San Francisco and had the largest newspaper circulation on the West Coast of the United States by 1880. Like other newspapers, it experienced a rapid fall in circulation in the early 21st century and was ranked 18th nationally by circulation in the first quarter of 2021. In 1994, the newspaper launched the SFGATE website, with a soft launch in March and official launch November 3, 1994, including both content from the newspaper and other sources. "The Gate" as it was known at launch was the first large market newspaper website in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backhoe
A backhoe—also called rear actor or back actor—is a type of excavating equipment, or digger, consisting of a digging bucket on the end of a two-part articulated arm. It is typically mounted on the back of a tractor or front loader, the latter forming a "backhoe loader" (a US term, but known as a "JCB" in Ireland and the UK). The section of the arm closest to the vehicle is known as the boom, while the section that carries the bucket is known as the dipper (or dipper-stick), both terms derived from steam shovels. The boom is generally attached to the vehicle through a pivot known as the king-post, which allows the arm to pivot left and right, usually through a total of 180 to 200 degrees. Description The term "backhoe" refers to the action of the bucket, not its location on the vehicle. That is, a backhoe digs by drawing earth backwards, rather than lifting it with a forward motion like a person shovelling, a steam shovel, or a bulldozer. The buckets on some backhoes m ...

Continuous Track
Continuous track is a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tires on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking. Modern continuous tracks can be made with soft belts of synthetic rubber, reinforced with steel wires, in the case of lighter agricultural machinery. The more common classical type is a solid chain track made of steel plates (with or without rubber pads), also called caterpillar tread or tank tread, which is preferred for robust and heavy construction vehicles and military vehicles. The prominent treads of the metal plates are both hard-wearing and damage resistant, especially in comparison to rubber tyres. The aggressive treads of the tracks provide good t ...

Concord, California
Concord ( ) is the largest city in Contra Costa County, California. According to an estimate completed by the United States Census Bureau, the city had a population of 129,295 in 2019 making it the eighth largest city in the San Francisco Bay Area. Founded in 1869 as Todos Santos by Don Salvio Pacheco II, a noted Californio ranchero, the name was later changed to Concord. The city is a major regional suburban East Bay center within the San Francisco Bay Area, and is east of San Francisco. History The valleys north of Mount Diablo were inhabited by the Miwok people, who hunted elk and fished in the numerous streams flowing from the mountain into the San Francisco Bay. It is important to note Miwok and other indigenous people still live within city limits. In 1772, Spanish explorers began to cross the area but did not settle there. In 1834, the Mexican land grant Rancho Monte del Diablo at the base of Mount Diablo was granted to Salvio Pacheco (for whom the nearby to ...

Palace Of Fine Arts
The Palace of Fine Arts is a monumental structure located in the Marina District of San Francisco, California, originally constructed for the 1915 Panama–Pacific International Exposition to exhibit works of art. Completely rebuilt from 1964 to 1974, it is the only structure from the exposition that survives on site. The most prominent building of the complex, a open rotunda, is enclosed by a lagoon on one side and adjoins a large, curved exhibition center on the other side, separated from the lagoon by colonnades. As of 2019, the exhibition center (one of San Francisco's largest single-story buildings) is used as a venue for events such as weddings or trade fairs. Conceived to evoke a decaying ruin of ancient Rome, the Palace of Fine Arts became one of San Francisco's most recognizable landmarks. Early 2009 marked the completion of a renovation of the lagoons and walkways and a seismic retrofit. History The Palace of Fine Arts was one of ten palaces at the heart of the ...

Pest Control
Pest control is the regulation or management of a species defined as a pest; any animal, plant or fungus that impacts adversely on human activities or environment. The human response depends on the importance of the damage done and will range from tolerance, through deterrence and management, to attempts to completely eradicate the pest. Pest control measures may be performed as part of an integrated pest management strategy. In agriculture, pests are kept at bay by mechanical, cultural, chemical and biological means. Ploughing and cultivation of the soil before sowing mitigate the pest burden, and crop rotation helps to reduce the build-up of a certain pest species. Concern about environment means limiting the use of pesticides in favour of other methods. This can be achieved by monitoring the crop, only applying pesticides when necessary, and by growing varieties and crops which are resistant to pests. Where possible, biological means are used, encouraging the natural en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agricultural Machinery
Agricultural machinery relates to the mechanical structures and devices used in farming or other agriculture. There are many types of such equipment, from hand tools and power tools to tractors and the countless kinds of farm implements that they tow or operate. Diverse arrays of equipment are used in both organic and nonorganic farming. Especially since the advent of mechanised agriculture, agricultural machinery is an indispensable part of how the world is fed. History The Industrial Revolution With the coming of the Industrial Revolution and the development of more complicated machines, farming methods took a great leap forward. Instead of harvesting grain by hand with a sharp blade, wheeled machines cut a continuous swath. Instead of threshing the grain by beating it with sticks, threshing machines separated the seeds from the heads and stalks. The first tractors appeared in the late 19th century. Steam power Power for agricultural machinery was originally suppli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
