Volcanic plume monitoring at mount Etna by diffusive(passive)sampling

2004

This paper reports the use of diffusive tubes in determining HF, HCI, and SO2 in the volcanic plume of Mount Etna in an attempt to highlight the potential of this method in studying volcanoes. In a first application a network of 18 diffusive tubes was installed on Etna's flanks, aimed at evaluating the atmospheric dispersion of the volcanic plume on a local scale. Results showed a monotonic decrease in volatile air concentrations with distance from the craters (HF from 0.15 to <0.003 μmol m-3 , HCl from 2 to <0.01 μmol m -3, and SO2 from 11 to 0.04 μmol m -3 ), revealing the prevalently volcanic contribution. Matching of SO2/HCl and HCl/HF volatile ratios with contemporaneous measurements a…

Eudontomyzon danfordi (Regan, 1911) Species Populations Ecological Status in Maramureş Mountains Nature Park (Romania)

2015

Abstract The Eudontomyzon danfordi characteristic habitats state of Maramureş Mountains Nature Park varies greatly, 19.05% are in excellent conservation status, 47.62% are in good/average status and 33.33% are in a partially degraded condition. The identified human impact categories which induced the decreasing of Eudontomyzon danfordi species habitat state in the studied area are: poaching, minor riverbeds morphodynamic changings, liquid and solid natural flow disruption, destruction of riparian trees and bush vegetation, habitat fragmentation-fish populations isolation, and organic/mining pollution activities.

The Conceptualisation and Measurement of Mega Sport Event Legacies

2007

This paper focuses on the legacy of mega sport events. First, the concept of legacy is defined before the problems of measuring and forecasting legacy are discussed. Benchmarking and the use of macro data do not correctly reveal legacy. Hence a bottom-up approach is introduced which identifies the event legacy by evaluation of ‘soft’ and ‘hard’ event-related changes in a host city. These changes are defined as ‘event-structures’ (infrastructure, knowledge, image, emotions, networks, culture). Many of them change the quality of location factors of the host city in the long-term. The benefits/costs through the transformation of the host city are the legacy of a mega sport event. Here a partic…

Tourism destination development: economic impacts evaluation due to intercultural food festivals

2014

The design and realization of events has become a relevant activity because it can accelerate the growth of European tourist destinations. Events provide a new demand for goods and services, which, in addition to local consumption, leads to an increase in revenues and employment. Moreover, when an event becomes an attractor, it generates new motivations for visiting a destination in addition to the traditional ones, which are generally linked to the presence of natural resources. While the issue can rely on extensive literature today, it established itself only at the end of the last century. Many authors have addressed the issue of the economic impact of events, amongst whom Grado, Strauss…

Global collaborative networks on meta-analyses of randomized trials published in high impact factor medical journals: a social network analysis

2014

Abstract Background Research collaboration contributes to the advancement of knowledge by exploiting the results of scientific efforts more efficiently, but the global patterns of collaboration on meta-analysis are unknown. The purpose of this research was to describe and characterize the global collaborative patterns in meta-analyses of randomized trials published in high impact factor medical journals over the past three decades. Methods This was a cross-sectional, social network analysis. We searched PubMed for relevant meta-analyses of randomized trials published up to December 2012. We selected meta-analyses (including at least randomized trials as primary evidence source) published in…

Evaluating Socio-economic Impact of Age-Friendly Environments

2018

According to the World Health Organization (WHO) (2007), physical and social environments are key determinants of whether people can remain healthy, independent and autonomous. Health and well-being are not only determined by our personal characteristics but also by the envi-ronment where we were born and where we live throughout our life (WHO 2015). In fact, promoting age-friendly environments (AFE) is the most effective approach for responding to demographic change because they empower elderly people to age in better health, they pro-mote their social inclusion and active participation, and they help them to live autonomously into old age (Parent 2012). AFE foster health, well-being and t…

Life cycle energy and environmental impacts of a solid oxide fuel cell micro-CHP system for residential application

2019

Abstract Fuel cells are considered one of the key technologies to reach the ambitious European goal of a low carbon economy, by reducing CO2 emissions and limiting the production of other pollutants. The manuscript presents an assessment of the life cycle energy and environmental performances of a solid oxide fuel cell system for household applications using primary data from the manufacturing phase and experimental data for the start-up and operation phases. The Life Cycle Assessment methodology is applied, based on a functional unit of 1 MJ of exergy and includes the life cycle steps from the raw materials extraction to the maintenance. The results show a particular relevance of the opera…

Processing and mechanical properties of organic filer-polypropylene composites

2005

The addition of organic fillers into thermoplastic polymers is an interesting issue, which has had growing consideration and experimentation during the last years. It can give rise to several advantages. First, the cost of these fillers is usually very low. Also, the organic fillers are biodegradable (thus contributing to an improved environmental impact), and finally, some mechanical and thermomechanical properties can be enhanced. In this study, the effect of the addition of different organic fillers on the mechanical properties and processability of an extrusion-grade polypropylene were investigated. The organic fillers came from natural sources (wood, kenaf, and sago) and were compared …
