Streptococcus lactarius sp. nov., isolated from breast milk of healthy women.
2011
Three strains of a hitherto-unknown, Gram-stain-positive coccus were recovered from the milk of three non-related healthy women. The isolates shared 99% 16S rRNA gene sequence similarity with sequences from uncultured members of the Lactobacillales and Streptococcus. The closest sequence corresponding to a defined species was that of Streptococcus peroris GTC 848T, with a similarity of 98%. A partial sequence (488 bp) of the tuf gene also showed 97% similarity with that of S. peroris CCUG 39814T. The combined 16S rRNA/tuf-based phylogeny revealed that all the isolates grouped in a statistically well-supported cluster separate from S. peroris. Enzyme activity profiles as well as fermentation…
Intention of coastal communities to support climate change mitigation policies for fish and marine ecosystem preservation
2021
Purpose This paper aims to assess the willingness of individuals living in coastal communities affected by climate change to financially support mitigation policies towards the preservation of marine ecosystems and fish resources and to identify the key drivers of their behaviour. Design/methodology/approach A survey was carried out involving 994 people living in three main Italian coastal communities. To investigate the main factors affecting Italian coastal communities’ willingness to pay (WTP) to support climate change mitigation measures to protect the marine ecosystem and fishery resources, a Tobit regression model was implemented. Findings The results show that these communities are …
Multicriteria evaluation of carbon-neutral heat-only production technologies for district heating
2018
Climate change mitigation requires reducing dependence on fossil fuels and transition to low carbon energy production technologies. Nearly half of the global final energy consumption is thermal energy produced from technologies with high carbon dioxide emission. As such, it is imperative to employ carbon-neutral heat production to achieve a sustainable energy system. This paper presents a real-life case of applying multicriteria decision analysis for evaluating carbon-neutral heat-only production technologies in a major district heating system in Finland. A group of 10 experts from the energy company contributed in defining the alternative technologies and multiple economic, technological, …
Sparsity-aware narrowband interference mitigation and subcarriers selection in OFDM-based cognitive radio networks
2016
In this paper, the performance of an orthogonal frequency division multiplexing overlay cognitive radio network with subcarrier selection schemes is investigated. We propose three subcarrier selection techniques that reduce the level of interference at the primary base station based on collected channel state information from the different network nodes. Approximated outage probability expressions are also derived and verified by simulations for the different studied techniques. In addition, we propose and investigate a new approach for asynchronous narrowband interference (NBI) estimation and mitigation in cognitive radio networks. The proposed approach does not require prior knowledge of …
The Energy System of Sicilian Region, Italy: 2014 situation and evolutionary trends
2015
The development of reliable energy scenarios are become increasingly more important and crucial due to scientific interest but also because it is essential for the deployment of effective energy policies in the territory. The depletion of Fossil Fuels and the need for the most industrialized countries to achieve the target of a sustainable development have induced important national, European and global initiatives. These actions have led to major changes on each energy system of countries and regions, contributing to the evolution of new local energy systems. In this paper, the Authors have collected, processed and analyzed the data concerning the evolution and changes of the Sicilian ener…
Evaluation of payment for ecosystem services in Mediterraneanforest: An empirical survey
2016
Abstract The relationship between humans and the forest has always been an important element, sometimes characterizing in the history of man himself. During the last years, the socio-economic context is profoundly changed, diversifying economic services provided by the forest. In the past, in fact, the primary function of the forest was the firewood production, while nowadays it grants several socio-economic benefits such as climate change mitigation, soil protection, protection and conservation of biodiversity, landscaping and recreational value. So, in recent decades a new type of socio-economic interest was developed in order to create a market of goods and services for the forests, call…
Estimation of urban structural flood damages: the case study of Palermo
2000
Abstract The estimation of flood damage is a fundamental step in the economic analysis of a flood control projects. In particular, frequency–damage functions, derived from the hydrologic, hydraulic and damage relationships, are one of the fundamental pieces of information upon which expenditure decisions are based. The aim of this study has been to develop an empirical frequency–damage relationship, obtained by means of detailed local studies, which could be a judgement tool for flood mitigation measures in strongly urbanised drainage areas. Monuments and other estates having a cultural or artistic significance have been specifically taken into account. The analysis has been carried out for…
Assessment of water shortage in urban areas
2007
Recent history has demonstrated that extreme hydrological events such as floods and droughts can create additional stress on water supplies essential for human and ecosystem health. As stated several times by European Environmental Agency, the prudent and efficient use of water is thus an important issue in Europe and a number of policies and mechanisms have been used or have been formulated to ensure sustainable use of water in the long term. Urban uses are responsible of almost the 17% of the total European fresh water consumption and they are rapidly growing depending on the extension of urban areas and concentration of population in cities. The present chapter will discuss the phases in…
