1 Renato Camargo Giacomini, Faculdade de Engenharia Industrial – Av.H.A.Castelo Branco, 3972 – S.B.Campo-CEP: 09850-901, [email protected] 2 Alessandro La Neve, Faculdade de Engenharia Industrial – Av.H.A.Castelo Branco, 3972 – S.B.Campo-CEP: 09850-901 – S.P., [email protected] Abstract New-technology extracurricular courses were offered to electronic engineering undergraduates. This experie...
Industrial and mining activities have been recognized as the major sources of soil heavy metal contamination. This study introduced an improved Nemerow index method based on the Nemerow and geo-accumulation index. Taking a typical industrial and mining gathering area in Tianjin (China) as example, this study then analyzed the contamination sources as well as the ecological and integrated risks....
Closing loops by intercompany recycling of by-products is a core theme of industrial ecology (IE). This article considers whether industrial recycling networks or industrial symbiosis projects can be used as a starting point for much broader intercompany cooperation for sustainable development. Evidence presented is based on the results of an empirical investigation of the recycling network Sty...
The present MYPLANET project responds to the first FP7-call “PEOPLE-INITIALTRAINING-ITN-2007-1” published by the European Commission. This collaborative initial training network represents a European initiative to train a new generation of engineers in the field of high performance computing applied to the numerical combustion simulation, energy conversion processes and related atmospheric poll...
The purpose of this study was to characterize spatial and temporal variations of carbonyl compounds in Gumi city, where a number of large electronic-industrial complexes are located. Carbonyl samples were collected at five sites in the Gumi area: three industrial, one commercial, and one residential area. Sampling was carried out throughout a year from December 2003 to November 2004. At one ind...
This research first focuses on the spatial and temporal patterns of heavy metals from contrasting environments (highly polluted to deepwater sites) of Lake Geneva. The mercury (Hg) and lead (Pb) records from two deepwater sites show that the heavy metal variations before the industrial period are primarily linked to natural weathering input of trace elements. By opposition, the discharge of ind...
This paper tries to demonstrate the importance of non-economic exogenous factors (Underlying Energy Demand Trend) when we estimate the industrial energy demand for Iran. The Structural Time Series Model (STSM) approach is used to model these unobservable factors. The Kalman filter and Maximum Likelihood methods allow us to estimate the value of the UEDT. This approach enables us to obtain more ...
for the past 3 decades, creating industrial clusters have been considered as an approach for the development of most small and medium enterprises. the goal of this programme is that all small and medium enterprises locating in a certain geoghraphic area can concentrate on cluster approach to collaborate in market research, production design, training and other activities that are not economical...
Eco-efficiency is an important sustainable development and circular economy construct that conceptualizes the relationship between industrial output, resource utilization, and environmental impacts. This paper conducts an eco-efficiency analysis for basin industrial systems using the decomposition model approach. Using data on 10 cities in China’s Songhua River basin, we illustrate the evolutio...
