O-carboxymethyl chitosan/gelatin/ silver-copper hydroxyapatite composite films with enhanced antibacterial and wound healing properties
(2022-08-21)Wound dressing composite films of O-carboxymethyl chitosan (OCMC) and gelatin were prepared and mixed with hydroxyapatite (HA) composited with Silver (Ag) and Copper (Cu) at different concentrations. The chemical, ... -
On Properties of Torsional Metric Spaces
(2018-08-09)We apply general tensor calculus to arbitrary nonrelativistic classical Lagrangian systems and derive general relationships between the torsion tensor and other quantities associated with the coordinate configuration space, ... -
On solutions of PDEs by using algebras
(2022-01-05)The components of complex analytic functions define solutions for the Laplace's equation, and in a simply connected domain, each solution of this equation is the first component of a complex analytic function. In this ... -
On the Cantor and Hilbert cube frames and the Alexandroff-Hausdorff theorem
(2021-10-01)The aim of this work is to give a point-free description of the Cantor set. It can be shown that the Cantor set is homeomorphic to the p-adic integers for every prime number p. To give a point-free description of the Cantor ... -
