Effect of Salinity on Phenolic Composition and Antioxidant Activity of Artichoke (Cynara scolymus L.) Leaves. Research Journal of Medicinal Plant, 6(3). Artichoke The globe artichoke ("Cynara cardunculus" var. "scolymus") is a variety of a species of thistle cultivated as a food. The edible portion of the plant consists of the flower buds before the flowers come into bloom. The budding artichoke flower-head is a cluster of many budding small flowers (an inflorescence), together with many bracts, on an edible base. Once the buds bloom,
Variety of finite semigroups equivalent to stating that "V" is closed under taking subsemigroup and under taking quotient The second property implie that the empty product - that is, the trivial semigroup of one element - belongs to each variety. Hence a variety is necessarily non-empty. A variety of finite (ordered) monoid is a variety of finite (ordered) semigroup whose elements are monoid. That is, it is a set of (ordered) monoid satisfying the two conditions stated above. In order to give the topological definition of a variety of finite semigroup, some other definitions related to profinite word are needed. Let "A" be an
