New spatiotemporally resolved LCI applied to photovoltaic electricity
نویسنده
چکیده
We present a new Life Cycle Inventory (LCI) calculation methodology that we call ESPA (Enhanced Structure Path Analysis). The ESPA method is aiming at calculating spatiotemporally defined LCIs while minimizing the difficulties of spatiotemporal information database management. The ESPA methodology uses the Structure Path Analysis capacity to describe completely the supply chain which enables the linkage of temporal distributions defined in the database. An example of electricity production by a multi-crystalline silicon 3 kWp installation is used to describe the ESPA capabilities in details. This new methodology underlines the need for the LCA community to discuss how temporal information should be described in future database. If used to its full potential, the ESPA methodology should enable a significant improvement in the representativeness of LCA results.

A spatiotemporally defined LCI is also needed to enhance the environmental impacts analysis and their optimization. Recent studies have shown that some environmental impact factors would require to be geodependently defined [3] and to be of use, the methodology requires a spatiotemporally defined LCI. Spatially defined LCI will also be useful to identify the sites of resources depletion and hig...

Angle-resolved low-coherence interferometry (a/LCI) is used to obtain quantitative, depth-resolved nuclear morphology measurements. We compare the average diameter and texture of cell nuclei in rat esophagus epithelial tissue to grading criteria established in a previous a/LCI study to prospectively grade neoplastic progression. We exploit the depth resolution of a/LCI to exclusively examine th...
