Menthol may also enhance the activity of glycine receptors and negatively modulate 5-HT 3 receptors and nAChRs. [11] Menthol is widely used in dental care as a topical antibacterial agent, effective against several types of streptococci and lactobacilli. [12] Menthol also lowers blood pressure and antagonizes vasoconstriction through TRPM8 ...
Menthone is a constituent of the essential oils of pennyroyal, peppermint, corn mint, pelargonium geraniums, and other plant species. [1] In most essential oils, it is a minor component. [5] Menthone was first synthesized by oxidation of menthol in 1881, [6] [needs update] [7] before being found as a component in essential oils in 1891.
The agriculture industry uses 500 tons per year as a fertilizer. In particular, its use has been suggested for treatment of whiptail in broccoli and cauliflower in molybdenum-deficient soils. [4] [5] However, care must be taken because at a level of 0.3 ppm sodium molybdate can cause copper deficiencies in animals, particularly cattle. [3]
{{Periodic table (melting point)|state=expanded}} or {{Periodic table (melting point)|state=collapsed}}This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.

The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
In Israel at Ashkelon on the Mediterranean coast, the world's largest reverse osmosis plant is producing 396,000 [6] m³ of water a day at around possibly US$0.50 per m³. [7] In western Saudi Arabia at Yanbu, production started in 1999 at 106,904 m³ of water a day. Later in 2009 with some expansion the production reached to 132,000 m³ of ...
Usually, permitted point sources of water pollution, such as wastewater treatment plants, have high discharge treatment costs, whereas nonpoint sources of water pollution, such as agriculture, have low costs of pollution reduction. Therefore, it is generally assumed that most trades would take place between point sources and nonpoint sources. [54]
