Elsevier is a world-leading provider of information solutions that enhance the performance of science, health, and technology professionals.
All knowledge begins as uncommon—unrecognized, undervalued, and sometimes unaccepted. But with the right perspective, the uncommon can become the exceptional.
That’s why Elsevier is dedicated to making uncommon knowledge, common—through validation, integration, and connection. Between our carefully-curated information databases, smart social networks, intelligent search tools, and thousands of scholarly books and journals, we have a great responsibility and relentless passion for making information actionable.

This paper illustrates the clash between interests and ideas concerning property rights and regulation by analyzing the ongoing debate on the right of public access in Sweden, which has recently intensified due to an influx of foreign professional berry harvesters. The conflicts in Sweden are found to stem from contradictory concepts concerning property (notably, ownership and the right of public access) and ideological differences in terms of whether forest resources should be regulated by government or governance.
Sugar-ethanol-electricity co-generation in Hawai’i: An application of linear programming (LP) for optimizing strategies
This research develops a linear programming (LP) model to assess various options for sugar and biofuel production from sugarcane and other feedstock in Hawaii. More specifically, the study focuses on finding optimal sugar and biomass feedstock that would maximize producer profits in the production of sugar, ethanol and electricity. Feedstock included in the model were sugarcane, banagrass, energy cane and sweet sorghum. Given available land resources for growing energy crops on the island of Maui, four land resource scenarios were considered.
Windtane contour map of the state of Texas
With the expansion of wind energy development, there is a need to update wind data periodically for the state of Texas for developers and landowners to see if their properties could support wind turbines. This study presents an updated wind power map and a Windtane contour map of the state of Texas. The Windtane map shows the height above ground level needed to reach a baseline wind power level of 350 W/m².
Modeling the dioxin emission of a municipal solid waste incinerator using neural networks
Incineration is considered as an efficient approach in dealing with the increasing demand for municipal and industrial solid waste treatment, especially in areas without sufficient land resources. Facing the concern of health risk, the toxic pollutants emitted from incinerators have attracted much attention from environmentalists, even though this technology is capable of reducing solid waste volume and demand for landfill areas, together with plenty of energy generation.
Evaluating Shuttle radar and interpolated DEMs for slope gradient and soil erosion estimation in low relief terrain
The error in slope gradient estimates provided by digital elevation models propagates to spatial modelling of erosion and other environmental attributes, potentially impacting land management priorities. This study compared the slope estimates of Shuttle Radar Topographic Mission (SRTM) DEMs with those generated by interpolation of topographic contours, at two grid cell resolutions. The magnitude and spatial patterns of error in DEM slope, and derived erosion estimates using the Revised Universal Soil Loss Equation (RUSLE), were evaluated at three sites in eastern Australia.
