In this work we reproduce the characterization of G s -sets from euclidean setting [11] to more general metric spaces. These sets have Hausdorff dimension at least and are closed by countable intersections, which is particularly useful estimate so called α -approximable points.

Tardif, C., Prefibers and the Cartesian product of metric spaces, Discrete Mathematics 109 (1992) 283-288. The properties of certain sets called prefibers in a metric space are used to show that the algebraic properties of the Cartesian product of graphs generalize to metric spaces.

this study was conducted to enhance the antimicrobial properties and water absorption of sanitary papers. for this purpose, montmorillonite nano clay with bentonite brand (has a layered structure in which its thickness is nano metric), was processed with homogenizer to achieve a stable colloidal system with nanometer dimensions of particle size. then, different weight levels of raw and homogeni...
