The aim of the paper is to prove that every smooth generalized vector subbundle D of a vector bundle E is the image of a smooth endomorphism Φ on the fibers of E that induces authomorphisms of fibers of D and is called here a natural anchor. Two new constructions of finite sets of smooth generators of the fibers of D are obtained, using any finite set of generators of the module Γ(E). Natural a...

The current research determines the most recent developments in natural fibres reinforced polylactic acid composites. Polylactic (PLA) is derived from renewable resources and capable of degrading microorganisms, eliminating pollution caused by petrochemical-based plastic. PLA promising biodegradable material among polymers since it easily attacked bacteria decomposes easily, releasing H2O, CO2,...
