The main aim of the paper is to investigate the possibility of substituting the thick and heavy thermal mass external walls used in high latitude countries by thin and light thermal mass ones whilst maintaining similar comfort levels throughout the year. To make this substitution the use of PCM...

Transgressive dune fields, which are active sand areas surrounded by vegetation, exist on many coasts. In some regions like in Fraser Island in Australia, small dunes shrink while large ones grow, although both experience the same climatic conditions. We propose a general mathematical model for...

Sand filters are commonly used to protect drip irrigation systems especially when large amounts of organic contaminants are present. Moreover sand filters have the advantage of simplicity and large capacities in comparison with other types of filters.

This work presents a theoretical analysis on savings of energy during an endothermic reaction under microwave heating compared to conventional heating and shows the use of metal coated bounding surface to enhance the energy savings in otherwise low saving zones. Main thrust of this work is the...

The manufacturing companies are one of the main consumers of energy. The increment in global warming and the instability in the petroleum oil market have motivated companies to find alternatives to reduce energy use. In the academic literature several researchers have demonstrated that...
