To be an alternative to fossil fuel, biodiesel should provide a positive energy benefit and a sustainable energy income. Based on the principles of Life Cycle Analysis and using the energy benefits of exploiting Pistacia chinensis in China as a case study, this paper presents a quantitative...

Bio-energy from energy plants is expected to play an increasing role in the future energy system, with benefits in terms of reducing greenhouse gas emissions and improving energy security. <em>Pistacia chinensis</em> is believed to be one of the most promising non-food input for biodiesel production....

<Para ID="Par1">Efficacy of phosphorus (P) mitigation strategies in lake basins could not be quantitatively evaluated due to a lack of assessment frameworks, confounding preferential management. The promiscuity in contributions of P sources to burden is a major cause. This study aimed to spatially profile water...</para>

Two heuristic procedures for a one-warehouse multi-retailer system are developed. Based on the accuracy desired, the first heuristic evaluates a specified number of points. The relative error is within a bound that approaches 1/(\root 2 ln 2) - 1 \approx 2.014%. The complexity of the heuristic...

Finding a best designed experiment based on balancing several competing goodness measures of the design is becoming more important in many applications. The Pareto front approach allows the practitioner to understand trade-offs between alternatives and make more informed decisions. Efficient...

We propose new specifications that explicitly account for information noise in the input data of bankruptcy hazard models. The specifications are motivated by a theory of modeling credit risk with incomplete information (Duffie and Lando [2001]). Based on over 2 million firm-months of data...

To investigate the status quo of heating supply and the impact of energy saving policies in northern China, a survey was conducted on the DHSs (district heating systems) in 15 Chinese cities. The average heating energy consumption was 19.2% lower than in 2008 due to the corresponding policies...

In order to study the development of organic agriculture in Taiwan in recent years, and based on relevant agriculture, economic and social statistics, the general scale of organic agriculture and industrial structure were treated with statistic analysis. Results suggest that the general scale of...

High energy prices, energy and environment security, concerns about petroleum supplies are drawing considerable attention to find a renewable biofuels. Biodiesel, a mixture of fatty acid methyl esters (FAMEs) derived from animal fats or vegetable oils, is rapidly moving towards the mainstream as...
