The Use of Landscape Indicators in Environmental Assessment
2016
A fundamental characteristic of the Strategic Environmental Assessment procedure is the use of indicator-like tools for measuring effects generated by plans and programmes that affect the environment and landscape. There are many kinds of indicator categories, but this chapter focuses attention on those related specifically to the landscape. Measuring many aspects of reality, by indicators, is easy today—but for landscape and its cultural aspects, the same fails to apply because, differently from water, air, soil and all the biotic and abiotic elements, technicians must consider variables in which the degree of subjectivity is very high. In spite of this reflection, Strategic Environmental …
Public availability of published research data in substance abuse journals
2014
[EN] Sharing research data is an increasingly necessary requirement for the advancement of science. The aim of this study was to analyse the policies on openness in sharing scientific research data in substance abuse journals. Journals included in the Substance abuse area of the Journal Citation Reports were used for the analysis, with reference to the instructions to authors published on the journals websites. In 67.6% of the journals, it is possible to store materials in thematic or institutional repositories; 47% accept supplemental material; 64.7% allow the reuse of data, and 41.2% admit the publication of their data on a website. Most journals recommend that authors deposit their data …
Guidelines to compare additive and subtractive manufacturing approaches under the energy demand perspective
2020
In order to characterise the environmental performance of additive manufacturing (AM) processes, comparative analyses are required. Different manufacturing approaches (such as additive and subtractive ones), besides adopting different equipment, use different kinds and amounts of material. Therefore, the material-related flow has to be followed throughout the entire product life. Differences in environmental impact arise at each step of the life cycle: material production, manufacturing, use, disposal, and transportation. A life cycle-based methodology able to take due account of all the factors of influence on the total energy demand for the production of metal components is given in this …
Influence of Material-Related Aspects of Additive and Subtractive Ti-6Al-4V Manufacturing on Energy Demand and Carbon Dioxide Emissions
2016
Summary The additive manufacturing of metal parts represents a promising process that could be used alongside traditional manufacturing methods. The research scenario in this field is still largely unexplored, as far as the technological solutions adopted to integrate different processes are concerned and in terms of environmental and economic impact assessment. In this article, an electron beam melting (EBM) process and a machining process have been analyzed and compared using a cradle-to-grave life cycle–based approach. The production of components made of the Ti-6Al-4V alloy has been assumed as a case study. The proposed methodology is able to account for all of the main factors of influ…
Easy removal of a large mucus plug with a flexible paediatric bronchoscope after administration of rhDNase (Pulmozyme).
2006
Mucoid impaction and plastic bronchitis are relatively rare disorders affecting patients of any age. Here we report the case of mucoid impaction developing in a four-year-old child as a complication of pneumonic infection treated four weeks prior. p.a. chest X-ray and fiberoptic bronchoscopy showed atelectasis and the location of a mucus cast in the left upper lobe. After extraction of the cast via the suction channel of the bronchoscope had failed, we administered 2.5 mg of undiluted recombinant human deoxyribonuclease (rhDNase) instilled directly over the affected area of occlusion for 15 minutes. This mucolytic agent mobilized the cast by reducing viscoelasticity and adherence of mucus. …
Impalement transitions in droplets impacting microstructured superhydrophobic surfaces
2008
Liquid droplets impacting a superhydrophobic surface decorated with micro-scale posts often bounce off the surface. However, by decreasing the impact velocity droplets may land on the surface in a fakir state, and by increasing it posts may impale droplets that are then stuck on the surface. We use a two-phase lattice-Boltzmann model to simulate droplet impact on superhydrophobic surfaces, and show that it may result in a fakir state also for reasonable high impact velocities. This happens more easily if the surface is made more hydrophobic or the post height is increased, thereby making the impaled state energetically less favourable.
Risorse culturali, ambientali e turismo sostenibile
2019
Il turismo sostenibilità richiede la capacità di integrare l’ambiente naturale, culturale e umano, nel rispetto del fragile equilibrio che caratterizza i territori, in modo da assicurare un’evoluzione appropriata per quanto riguarda le capacità di mitigazione dell’impatto antropico, e che sappia valutare i propri effetti sul patrimonio culturale, naturale e sulle comunità locali. Sustainability tourism requires the ability to integrate the natural, cultural and human environment, respecting the fragile balance that characterizes the territories, in order to ensure an appropriate evolution as regards the capacity to mitigate the anthropic impact, and that it knows assess their effects on cul…
Ways of Promoting Cultural Ecotourism for Local Communities in Sibiu Area
2014
Abstract Now, Romanian tourism is being confronted with problems of infrastructure and image, and this is a reason we consider that the chance of sustainable development of this area is being represented by promoting niche tourism, namely cultural ecotourism. In an age of globalization, the authentic cultural patrimony is that which makes the difference and represents an opportunity for sustainable development of local communities. The essence of sustainable development is represented by the harmonious integration of economic development, by responsible governing, by ensuring the social cohesion and community man - nature. By the attested value cultural ecotourism can become a touristic pro…
Environmental effects of tourism and its seasonality on Mediterranean islands: the contribution of the Interreg MED BLUEISLANDS project to build up a…
2020
AbstractThe Mediterranean basin is amongst the world’s main tourist destination, and its islands are a major attraction, being sites of historical, cultural and naturalistic importance. This is beneficial for the local economies, but it may also represent a great burden on the coastal environment, where other human pressures are concentrated. The awareness of detrimental side effects of tourism together with the importance to take into account social and economic facets has led to the concept of sustainable tourism, which, however, represents a goal far from being attained. A good opportunity to promote sustainable tourism was provided by the Interreg MED BLUEISLANDS project, whose main aim…
ICT and tourism impacts in islands
2018
New technologies can represent, for some aspects, both a problem and a precious resource. As we concerns, in tourism sector, ICT can help in managing and promoting destinations in a better way than in the past, especially in those cases where problems linked with the management of tourist flows and the need to manage a sustainable development exists. Monitoring tourism impact at the destination is a fundamental issue in order to respect the right pressure and to avoid negative effects in the destination and with the residents. There are several devices available and useful for different needs, therefore almost each kind of monitoring and analysis can be supported by the right tools. This kn…
