Brasenia is cultivated as a vegetable in China (where it is known as chúncài 莼菜) and where it is used in Hangzhou in the well-known local speciality "West Lake Water Shield Soup" [15] and in Japan. The mucilage it produces has been found to have anti-algal and anti-bacterial properties that may be useful as a natural weed control. [16]
A common name for its species is water shield. [4] The family is recognised as distinct in the Angiosperm Phylogeny Group IV system (2016). The family consists of two genera of aquatic plants, Brasenia and Cabomba, totalling six species. [5] Submerged leaf of Cabomba caroliniana A.Gray with scale bar (2 cm) on a white background
Gear oil being added to the final reduction gears in a scooter. EP additives which contain phosphorus/sulfur compounds are corrosive to yellow metals such as the copper and/or brass used in bushings and synchronizers, unless properly buffered; the GL-1 class of gear oils does not contain any EP additives and thus used to be the choice in ...

The modern oilskin garment was developed by a New Zealander, Edward Le Roy, in 1898. Le Roy used worn-out sailcloth painted with a mixture of linseed oil and wax to produce a waterproof garment suitable to be worn on deck in foul-weather conditions. Oilskins are part of the range of protective clothing also known as foul-weather gear.
The line includes engine oils, gear oils and coolants. The oil carries both the American Petroleum Institute (API) diesel "C" rating as well as the API gasoline engine "S" rating. Ratings differ based on the oil. Rotella oils, like the T3 15W-40, meet both the API CJ-4 and SM specifications, and may be used in both gasoline and diesel engines.
On the other hand, rain water or salt water affects DWRs less significantly. [citation needed] Affected garments can be treated with a 'spray-on' or 'wash-in' treatment to improve water-repellency. In some cases heat treatment can reactivate the factory applied repellent finish and aid in the repelling of water, and other liquids such as oils.
Oil leaks from running machinery such as diesel generators, air compressors, and the main propulsion engine. Modern OWSs have alarms and automatic closure devices which are activated when the oil storage content of the waste water exceeds a certain limit(15ppm : 15 cm3 of oil in 1m3 of water).
