According to its abstract, the article presents “a method to determine the nontrivial colorings of perfect and transitive 2-uniform tilings.” The second article entitled “Effect of Ingredient Loading on Surface Migration Kinetics of Additives in Vulcanized Natural Rubber Compounds” examines the surface migration kinetics of chemical additives in vulcanized natural rubber compounds as a function of ingredient loading. Bryan Pajarito, Christia Angela de Torres, and Marienne Maningding wrote the article.

The third article “An Account of the Accessioned Collections of the UP Biology Invertebrate Museum” is by Ronniel D. C. Pedales and Gizelle A. Batomalaque.
