Assume that 8 people are seated around a table and we want to enumerate the number of ways that they can be permuted such that neighbors are no more neighbors after the rearrangement. Of course the answer depends on the topology of the table: if the table is a circle then it is easy to check by a simple computer program that the permutations that verify this property are 2832, if it is a long b...

the interest of dental research in metal-free restorations has been rising in the last 20 years following the introduction of innovative all-ceramic materials in the daily practice. in particular, high-strength ceramics and related cad/cam techniques have widely increased the clinical indications of metal-free restorations, showing more favorable mechanical characteristics compared to the early...
In this paper, we introduce a new algebraic structure, called a UP-algebra (UP means the University of Phayao) and a concept of UP-ideals, UP-subalgebras, congruences and UP-homomorphisms in UP-algebras, and investigated some related properties of them. We also describe connections between UP-ideals, UP-subalgebras, congruences and UP-homomorphisms, and show that the notion of UP-algebras is a ...
