Ki-67 immunoexpression and radiological assessment of necrosis improves accuracy of conventional and modified core biopsy systems in predicting the f…

2021

Based on the French Federation Nationale des Centers de Lutte Contre le Cancer (FNCLCC) grading system, this study assesses the accuracy of conventional and modified core biopsy (CB) systems in predicting the final grade (low vs high) assigned to the resected specimen. Substituting Ki-67 immunoexpression for mitotic count, and radiological for histological assessment of necrosis, we used two modified FNCLCC CB grading systems: (1) Ki-67 immunoexpression alone, and (2) Ki-67 plus radiological assessment of necrosis. We graded 199 soft tissue sarcomas (STS) from nine centers, and compared the results for the conventional (obtained from local histopathology reports) and modified CB systems wit…

The cost of green roofs disposal in a life cycle perspective: covering the gap.

2012

Abstract This study is aimed at providing a contribution in overcoming the current gap, especially in Life Cycle Costing (LCC) and Benefit – Cost (BCA) analyses, due to the lack concerning the green roof disposal costs. Therefore, we have applied to an actual extensive green roof the LCC methodology suggested by D. G. Woodward (that appears like one of the most formalized and generalizable), but we have extended the analysis to the disposal phase. This will allow a complete and proper application of the LCC methodology in order of achieving an economic accounting of this component through its life cycle. In this way, it is possible to achieve the complete evaluation of the “green roof” perf…

The role of the cognitive model profile in knowledge representation and meaning construction: the case of the lexical item Europe

2017

The paper addresses the role of the cognitive model profile, one of the fundamental constructs in LCCM Theory (a.k.a. access semantics), in meaning construction and knowledge representation with respect to the concept of Europe. The study is based on a corpus of news articles retrieved from the Guardian from May 2004 through December 2009 (approximately 930,000 words) and focuses on the lexical item Europe (over 4000 corpus occurrences). The study takes its theoretical underpinnings from LCCM Theory, a theory of lexical representation and semantic composition, which delineates the roles the linguistic and the conceptual systems play in meaning construction (e.g., Evans 2009, 2013). The pape…

Economic and environmental sustainability of submerged anaerobic MBR-based (AnMBR-based) technology as compared to aerobic-based technologies for mod…

2015

[EN] The objective of this study was to assess the economic and environmental sustainability of submerged anaerobic membrane bioreactors (AnMBRs) in comparison with aerobic-based technologies for moderate-/high-loaded urban wastewater (UWW) treatment. To this aim, a combined approach of steady-state performance modelling, life cycle analysis (LCA) and life cycle costing (LCC) was used, in which AnMBR (coupled with an aerobic-based post-treatment) was compared to aerobic membrane bioreactor (AeMBR) and conventional activated sludge (CAS). AnMBR with CAS-based post-treatment for nutrient removal was identified as a sustainable option for moderate-/high-loaded UWW treatment: low energy consump…

ENVIRONMENTAL AND ENERGY PERFORMANCES OF BUILDING PRODUCTS: A WORKING CHAIN BASED ANALYSIS

2014

The present work is aimed at investigating the environmental and energy performances of products to be utilized in buildings. Specifically, marble (Section 1), granite (Section 2) and natural materials (Section 3) will be analyzed. The marble features are here studied on the basis of a field working chain audit. Particularly, two representative firms of the Custonaci productive basin (Trapani) have been considered. Their working chain have been investigated, by the point of view of the energy and materials flows, with a classical Life Cycle Assessment (LCA) approach. Moreover, the social and economic impacts of such materials have also been assessed by means of the Life Cycle Costing (LCC) …

LCA of Different Construction Choices for a Double-Track Railway Line for Sustainability Evaluations

2023

The international commitment to achieve carbon neutrality in the next few decades has oriented human activities towards the preservation of natural and non-renewable resources. In this context, a great research effort has been devoted to the search for sustainable solutions for the infrastructure construction sector, based on a thorough assessment of the environmental impact (EI). In this regards, Life Cycle Assessment (LCA) is considered one of the main components of Environmental Impact Assessment (EIA) and, for a comprehensive analysis, all the costs incurred by stakeholders during the useful life of the infrastructure should also be taken into account, applying the Life Cycle Cost (LCC)…
