This paper studies the efficiency of subgrade stiffening next to the track as a mitigation measure for railway induced vibrations by means of a two-and-a-halfdimensional coupled finite element – boundary element methodology. The pyhsical mechanism is interpreted in the frequency–wavenumber domain, illustrating that the stiffened block of soil next to the track can act as a wave impeding barrier...

Power sector is responsible for about 40% of the total CO₂ emissions in the world and plays a leading role in climate change mitigation. In this study, measures that lower CO₂ emissions from the supply side, demand side, and power grid are discussed, based on which, an integrated optimization model of CO₂ mitigation (IOCM) is proposed. Virtual energy, referring to energy saving capacity in both...

1. Executive summary The Mitigation Options for Phosphorus and Sediment (MOPS) project aimed to investigate the efficacy and cost-effectiveness of different in-field mitigation options which could be used to control diffuse pollution losses in surface runoff from arable fields under combinable crops. In order to achieve this, a literature review, field experimentation, and economic analysis wer...

Wildlife-vehicle collisions, especially with deer (Odocoileus spp.), elk (Cervus elaphus) and moose (Alces alces) are numerous and have shown an increasing trend over the last several decades in the United States and Canada. We calculated the costs associated with the average deer($6,617), elk($17,483) and moose-vehicle collision ($30,760), including vehicle repair costs, human injuries and fat...

Ensuring access to safe drinking water by 2015 is a global commitment by the Millennium Development Goals (MDGs). In Bangladesh, significant achievements in providing safe water were made earlier by nationwide tubewell-installation programme. This achievement was overshadowed in 1993 by the presence of arsenic in underground water. A total of 6 million tubewells have been tested for arsenic sin...
