This paper presents a systems analysis perspective that extends the traditional process design framework to green process design, green energy and industrial ecology leading to sustainability. For green process design this involves starting the design decisions as early as chemical and material selection stage on one end, and managing and planning decisions at the other end. However, uncertaint...

This paper considers the limits and potential of ‘urban metabolism’ to conceptualize city processes. Three ‘ecologies’ of urban metabolism have emerged. Each privileges a particular dimension of urban space, shaped by epistemology, politics, and model-making. Marxist ecologies theorize urban metabolism as hybridized socionatures that (re)produce uneven outcomes; industrial ecology, as stocks an...

Introduction The following document explores some critical points connected with the possible adoption of ecosystem models for industrial production. It is necessitated by the desire to underscore some fundamental questions possibly arised by policies trying to introduce or implementing forms of systemic interaction for firms. Such questions are essentially directed to a better knowledge about ...

Higher tier studies to assess the environmental risks of pesticides have been performed mainly in Atlantic Central Europe and North America and results of such studies have been extrapolated to other climatic regions such as South Europe (Ramos et al. 2000; López-Mancisidor et al. 2008a). Since climate (e.g., sun hours, rainfall, temperature), agroecosystems (e.g., crop rotation, field size), a...

Arbuscular mycorrhizal fungi (AMF) are critical links in plant-soil continuum and play a critical role in soil carbon cycles. Soil respiration, one of the largest carbon fluxes in global carbon cycle, is sensitive to precipitation change in semiarid ecosystems. In this study, a field experiment with fungicide application and water addition was conducted during 2010-2013 in a semiarid steppe in ...

Hydrographic data from the Antarctic Drifter Experiment: Links to Isobaths and Ecosystems (ADELIE) project are analyzed to determine the frontal structure and transport along a section across the continental shelf and slope in the northwestern Weddell Sea. The flow is dominated by three barotropic northward flowing currents: the Antarctic Coastal Current, the Antarctic Slope Front and theWeddel...

Integrated, real-time and open approaches relating to the development of industrial analytics capabilities are needed to support smart manufacturing. However, adopting industrial analytics can be challenging due to its multidisciplinary and cross-departmental (e.g. Operation and Information Technology) nature. These challenges stem from the significant effort needed to coordinate and manage tea...

The paper illustrates some aspects of energy conversion processes during underground electric train operation. Energy conversion processes are explained using exergy, in order to support transport system sustainability. Loss of exergy reflects a loss of potential of energy to do work. Following the notion that life in Nature demonstrates sustainable energy conversion, we approach the sustainabi...
