In this paper we present an approach which aims to support learners in general and environmental decision makers in particular, towards effective decision making in maritime environmental pollution via education and awareness of specific maritime environmental pollution policies. We build on previous work concerning the automatic construction of multiple-choice questions from ontologies (automa...

Background & Aims of the Study: The heterotrophic bacteria are widely used as a water microbial pollution index for drinking water. The aim of this study was to investigate the effect of metallic nanoparticles such as Zero Valent Iron (ZVI), Titanium dioxide (TiO2) and Zinc oxide (ZnO) on Heterotrophic Bacter...

It is shown that certain metallic photonic crystals can enable negative refraction and subwavelength imaging without relying on a negative effective index. These metallic structures are very simple in design and appear straightforward for fabrication. Their unusual electromagnetic response should provide an interesting comparison with the metallic left-handed materials.

We analyze non-cooperative environmental policy when the only strategic interaction between countries is through bilateral transboundary pollution, i.e., countries are closed or small open economies. When countries set pollution taxes simultaneously, there is no carbon leakage. However, in the sequential-move game, the leader sets its pollution tax lower than the marginal damage from own pollut...

Increasing attention is being paid to spatial distribution characteristics of haze pollution and its relation with socioeconomic factors. This study investigates the spatial autocorrelation of haze pollution in China and the effect of foreign direct investment (FDI) on haze pollution in China using a panel data of 31 provinces over the period 2000-12. Using a widely used spatial autocorrelation...

The backscattering contribution to the conductivity, irrelevant for metallic single-walled carbon nanotubes, is proved to become much significant for doped semiconducting systems, in agreement with experiments. In the case of multi-walled nanotubes, the intershell coupling is further shown to enhance the contribution of backscattering for ”metallic” double-walled, whereas it remains insignifica...

Environmental pollution is one of the serious crisis to which we are facing today. It is fact that three basic elements air, water and land which constitute harmony of nature for proper and balance living of all organisms, it was fortunate enough that such hospitable and balance environment was the destiny of our predecessors. But it is contrary to living of the present environment. With the ra...

in this paper, the evidences and remnants of archaeometallurgical activities in elamite site of haft tappeh (14th century bc) have investigated and identification of archaeometallurgical materials have been done based on analytical investigations. sem-eds analysis and metallography were used to identify the chemical composition and microstructural features of archaeometallurgical materials in h...

Abstract Because of its multiple advantages such as durability, flexibility in use, fire resistance and low production maintenance costs, concrete is, by far, the most popular building material currently use. However, cement – one base ingredients requires large quantities raw materials fossil fuels order to be produced. In fact, terms pollution, it is environment-damaging products construction...
