A novel and green approach was adopted for the synthesis of 3,4-dihydropyrimidin-2(1H)-one/thiones derivatives using Punica granatum peel as an inexpensive, efficient and mild catalyst under solvent-free condition. The ...

Magnetic calcined oyster shell functionalized with taurine immobilized on
β-cyclodextrin (
Fe3O4/COS@β-CD-SO3H NPs) was prepared as a new stable, longlived,
highly efficient, and exceptional reusable magnetic ...

For a locally compact abelian group $G$ we give a necessary and sufficient condition

for shifts of a function $\\phi\\in L_2(G)$ to be a Riesz family. Also for a finite family

$\\Phi$ of compactly supported ...

We consider a locally compact abelian group G with a uniform lattice L in G. In this paper necessary and

sufficient condition under which shifts of a finite numbers of functions {φ1, φ2, · · · , φn} in L
