A multilayer porous film, comprising a porous layer including inorganic particles and a resin binder on at least one surface of a porous film containing a polyolefin resin as a main component, wherein the inorganic particles contain an aluminum silicate compound as a main component. The voice integration platform comprises one or more generic software components, the generic software components being configured to enable development of a specific voice user interface that is designed to interact with the data system in order to present the stored data to a user. The prosthetic component can include an attachment profile that corresponds to a mating profile formed on or in a bone. The light can be rotated with a motor and a belt by a rotating mechanism, while allowing the optical axes of the light to match each other at the same focal position. A second plastic portion is molded between and over the protrusions of the first plastic portion, thereby forming a protuberance on the plastic article in a desired profile.
