thousands if not millions within a short span of time. In terms of cancer and general human health, plastic has become an important issue. Plastic is a concern for both the environment and for the health conscious. Plastic is a synthetic material created by combining materials derived from sources such as petroleum, natural gas or coal. These polymers then must be combined with additives to give the finished product properties such as flexibility or toughness (Life Without Plastic and Mama Mundo Inc., 2013)

surface. Aerogels as a whole are made by creating a gel then extracting the solvent with supercritical fluid extraction. This leaves a very porous, low-density solid. Due to their porous nature, aerogels are considered to be the finest insulation materials available. Silica aerogels are good insulators, but will flake apart and produce dust in the Mars atmosphere. For this reason, all-polymer aerogels should be used over their silica-based counterparts. They can be created as thin, flexible films and

Relationship between Kmax and σf Kannan et al. [23] had examined the applicability of a modified two-parameter fracture criterion MTPFC which introduced by Christopher et al. [24, 25] while assessing the fracture strength of structure components. They utilized a relation between the stress intensity factor (Kmax) and the corresponding stress at failure (σf) as (2) where σf is the hoop stress at the failure pressure

disc can also be used as well. In this application, the film will be more uniform and we will be able to save 10 to 15 percent of the material because there will be a reduction in the overspray. There are many low prices units available. A high voltage electrostatic charge is applied to the workpieve and the sprayer mechanism. Both powdered and liquid paint materials can be used The overpack is first sprayed with or dipped with paint particles which are

My brother John worked there too and my brother Brian got sent away. One

strain response of two different materials were measured as stress was applied to them. The materials were an aluminum rod and a chicken bone. Strain (ᵋ) is the change of length of the material over the initial length. As we increase the stress on the material, there will be an increase on the strain on the material as well. Stress is the force (F) over cross-sectional area (A) applied on the material. The area is constant, so stress can

office. Spofforth said that in addition to the surplus packaging, many of the materials used to package the products were non-recyclable. Most of the manufacturers of the products cited said they were sensitive to environmental concerns and that their packaging was designed to protect the integrity of the products. A few also said that they were changing their packaging to more environmentally friendly materials. "Even before we heard from these groups, we had taken the initiative," said
