Frontiers in Plant Science, 2021 In sub-Saharan Africa (SSA), vitamin A deficiency (VAD) is a major cause of blindness in children under 5 years. Sweetpotato (Ipomea batatas L.) is widely grown in this region, and pro-vitamin A varieties could help to combat such problems.

Varieties of bounded K-lattices
Fuzzy Sets and Systems, 2022 In this paper we continue to study varieties of K-lattices, focusing on their bounded versions. These (bounded) commutative residuated lattices arise from a specific kind of construction: the {\em twist-product} of a lattice. Twist-products were first considered by Kalman in 1958 to deal with order involutions on plain lattices, but the extension of ...

Varieties of Lattices with Geometric Descriptions [PDF]
Order, 2011 A lattice L is spatial if every element of L is a join of completely join-irreducible elements of L (points), and strongly spatial if it is spatial and the minimal coverings of completely join-irreducible elements are well-behaved. Herrmann, Pickering, and Roddy proved in 1994 that every modular lattice can be embedded, within its variety, into an ...

All Regular-Solid Varieties of Idempotent Semirings
Discussiones Mathematicae - General Algebra and Applications, 2017 The lattice of all regular-solid varieties of semirings splits in two complete sublattices: the sublattice of all idempotent regular-solid varieties of semirings and the sublattice of all normal regular-solid varieties of semirings.

CHIMIA, 1975 As colloidal manganese oxide hydroxides in natural waters occur in an infinity of finely divided varieties of an apparently limited number of (unknown) phases, an attempt has been made to prepare standard samples of the so-called “10 Å phase” which we ...

The Amalgamation Property for Varieties of Lattices [PDF]
Transactions of the American Mathematical Society, 1984 There are precisely three varieties of lattices that satisfy the amalgamation property: trivial lattices, distributive lattices, and all lattices.
