A Study of Car-to-Train Assignment Problem for Rail Express Cargos on Scheduled and Unscheduled Train Service Network

Freight train services in a railway network system are generally divided into two categories: one is the unscheduled train, whose operating frequency fluctuates with origin-destination (OD) demands; the other is the scheduled train, which is running based on regular timetable just like the passenger trains. The timetable will be released to the public if determined and it would not be influence...

Microalgal biomass production pathways: evaluation of life cycle environmental impacts

BACKGROUND Microalgae are touted as an attractive alternative to traditional forms of biomass for biofuel production, due to high productivity, ability to be cultivated on marginal lands, and potential to utilize carbon dioxide (CO2) from industrial flue gas. This work examines the fossil energy return on investment (EROIfossil), greenhouse gas (GHG) emissions, and direct Water Demands (WD) of ...

study of environmental impacts for potato agroecosystems of iran by using life cycle assessment (lca) methodology

life cycle assessment (lca) had proven to be an appropriate assessment tool for analysis of agri-food products by identifying, quantifying and evaluating the resources consumed and emissions released into the environment. this study was performed for evaluation the environmental impacts of potato agroecosystems based on nitrogen levels by using lca methodology. tuber yield mean during 1999-2013...

Life-Cycle Assessment methodology: a tool for the evaluation of environmental and toxicological impacts of ammunitions

Over the last ten years the environmental concerns associated with the military activities have increased due to legislation pressure and an increasing awareness to the environmental issues. Such situation has leaded the defence industry and the Armed Forces to seek for a tool to evaluate the environmental burdens associated with ammunitions. Some methodologies have been applied to evaluate the...
