A Simple Metal-Free Cyclization for the Synthesis of 4-Methylene-3-Substituted Quinazolinone and Quinazolinthione Derivatives: Experiment and Theory

open access: yesFrontiers in Chemistry, 2019
A new series of 3-substituted 4-methylene-quinazolinthiones and 4-methylene-quinazolinones were synthesized in moderate to excellent yield through a simple reaction of 2-aminoacetophenones with isocyanates or isothiocyanates.

Isomorphism of modular group algebras of finite torsion-free rank coproducts of p-mixed countable abelian groups

open access: yesLe Matematiche, 2006
Suppose G is with finite torsion-free rank a coproduct of p-mixed countable abelian groups and F is a field with characteristic p such that the group algebras FG and FH are F -isomorphic for another group H . Then G and H are isomorphic.

Normal Lie subsupergroups and non-abelian supercircles

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
We propose and study an appropriate analog of normal Lie subgroups in the supergeometrical context. We prove that the ringed space obtained taking the quotient of a Lie supergroup by a normal Lie subsupergroup, is still a Lie supergroup.

Coproducts and ultrafilters

open access: yesJournal of Pure and Applied Algebra, 1987
The paper studies connections between ultrafilters (in connection with measurable cardinals) and coproduct preservation properties of functors. Let \(\alpha\) be a cardinal. Define an \(\alpha\)-coproduct (in a category) to be a coproduct indexed by a set of cardinality \(

Subpullbacks and coproducts of $S$-posets [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2015
In 2001, S. Bulman-Fleming et al. initiated the study of three flatness properties (weakly kernel flat, principally weakly kernel flat, translation kernel flat) of right acts $A_{S}$ over a monoid $S$ that can be described by means of when the functor ...

Coproduction in Municipal Education Councils: possibilities for the coproduction of control

open access: yesLinhas Críticas, 2023
Este artigo tem como objetivo examinar teoricamente as possibilidades de atuação dos Conselhos Municipais da Educação (CMEs) na coprodução do bem público, por meio dos Planos Municipais de Educação (PMEs) e da coprodução do controle. Os CMEs são espaços propícios à coprodução do controle, visto que sua natureza formativa, funções e atribuições ensejam ...

From entangled codipterous coalgebras to coassociative manifolds

open access: yes, 2003
We construct from coassociative coalgebras, bialgebras, Hopf algebras, new objects such as Poisson algebras, Leibniz algebras defined by J-L Loday and M.

Quasitriangular Structures of Bicrossed Coproducts

open access: yesJournal of Algebra, 1998
Let \(H\) and \(A\) be two bialgebras (Hopf algebras) coacting on each other. The tensor product \(H\otimes A\) is endowed with a bialgebra (Hopf algebra) structure, called the bicrossed coproduct of \(H\) and \(A\). An example is the dual of the Drinfeld double of a Hopf algebra.

Effect of Temperature and pH on Microbial Communities Fermenting a Dairy Coproduct Mixture

open access: yesFermentation
Organic-rich industrial residues can serve as renewable feedstocks for the generation of useful products by microbial fermentation. We investigated fermenting communities enriched in a mixture of ultra-filtered milk permeate (UFMP) and acid whey from ...
