the aim of the present study was to examine the periodontal condition of an adult population in three isolated regions in greece and to determine the association of periodontal disease with several demographic, behavioral and environmental factors.the study population consisted of 640 individuals, aged 20 to 69 years from three isolated regions. the following indices were assessed: pocket depth...

Any intermediate propositional logic (i.e., a including intuitionistic and contained in classical logic) can be extended to calculus with epsilon- tau-operators critical formulas. For logic, this results Hilbert’s -calculus. The first second -theorems for establish conservativity of the -calculus over its base logic. It is well known that -theorem fails -calculus, as prenexation impossible. pap...

The paper discusses fractional integrals and derivatives appearing in the so-called (q, h)-calculus which is reduced for h = 0 to quantum calculus q 1 difference calculus. We introduce delta as well nabla version of these notions present their basic properties. Furthermore, we give comparisons with known results discuss possible extensions more general settings.

Quantum calculus (also known as the q-calculus) is a technique that similar to traditional calculus, but focuses on concept of deriving q-analogous results without use limits. In this paper, we suggest and analyze some new q-iterative methods by using q-analogue Taylor’s series coupled system technique. domain q-calculus, determine convergence our proposed q-algorithms. Numerical examples demon...
