Crisis in the availability of energy sources hints that proper usage of the available sources is an essential factor in order to keep the balance of the energy sources on earth. The modern usage of resources indicates a change among the human beings from an understanding of the balance of nature to focusing more on expansions.

Conversely, the polymers used in the study are PVC and Polypropylene. The investigation surrounds the argument that the chemical composition of a material has far reaching impact on the mechanical properties of such material. Therefore, the investigation sought to bolster this argument by carrying out a test on mechanical properties of steel and polymers, which include hardness, tensile strength, % elongation, impact test, and yield strength.

This dependency on oil to solely fuel nations has led to what is called oil based world economy (Kumhof & Dirk 20). Not all counties have this reserve and this is where the challenge comes in. Very few countries are able to harness oil and due to the increase in its demand each year due to increase in population, the price of oil has been on an increase steadily over the years.

The composition of steel contains numerous defects such as solute atoms. Creep increases as steel nears its melting point (Totten, 2007). Creep is a ‘time-dependent’ deformation which means that it does not occur suddenly. Creep occurs gradually as a result of long term stress due to high temperatures.

This paper briefly examines the advantages and disadvantages of building with AAC, paying specific attention to the aspects of the product that may lend to its designation as a sustainable building materia

By the end of the ninetieth century, London had grown so much, but motorists and pedestrians were restricted to use of a single bridge, which would be used to move in and out of the city. The Londoners waited for the completion of the New Bridge by Sir H. Jones, and Sir J.W. Barry, who devised the idea of a bascule bridge with two towers.

In broadcasting interactions is usually achieved by regulating a physical attribute of a sinusoidal conveyor, the frequency (rate of reoccurrence), phase, amplitude or an amalgamation of the three. This is executed in real schemes with a modulation technique at the conveying point to compel the substantial conversion at the deliverance and a demodulation technique at the receiving end to sense the consequential modulation on response.
