Edible seaweed Edible seaweed Edible seaweed, or sea vegetables, are algae that can be eaten and used in the preparation of food. They typically contain high amounts of fiber. They may belong to one of several groups of multicellular algae: the red algae, green algae, and brown algae. Seaweeds are also harvested or cultivated for the extraction of polysaccharides such as alginate, agar and carrageenan, gelatinous substances collectively known as hydrocolloids or phycocolloids. Hydrocolloids have attained commercial significance, especially in food production as food additives. The food industry exploits the gelling, water-retention, emulsifying and other physical properties of these hydrocolloids. Most edible
Conductor of an abelian variety Conductor of an abelian variety In mathematics, in Diophantine geometry, the conductor of an abelian variety defined over a local or global field "F" is a measure of how "bad" the bad reduction at some prime is. It is connected to the ramification in the field generated by the torsion points. For an abelian variety "A" defined over a field "F" as above, with ring of integers "R", consider the Néron model of "A", which is a 'best possible' model of "A" defined over "R". This model may be represented as a scheme over (cf. spectrum of a ring) for
