Designing and developing location-aware portable software applications is challenging, since most location-estimation methods i) require non-standard features either in the mobile terminal or in the network infrastructure, and ii) they are specifically designed for either indoor or outdoor. Moreover, installing and tuning systems that rely on such location(More)
In the north-western region of Somalia, bordering Ethiopia, sorghum represents an important resources for human and animal nutrition. The critical situation of Somalia is threatening the preservation of this valuable resource and it becomes urgent to develop a strategy of correct evaluation of the sorghum germplasm in order to promote conservation and(More)
The aim of this study was to evaluate the influence of short-term dietary intake of bread obtained by a selected variety of old grain grown in Tuscany, Italy on some parameters related to the atherosclerotic process. Twenty healthy subjects (median age, 39.5 years) followed for 10 weeks a diet containing bread (150 g/day) made from the test grain (test(More)
BACKGROUND The present study was aimed at examining the effect of tuber mineral composition, distinctive for geographical location, on the expression of acrylamide precursors in three potato genotypes (Arinda, Rossa di Cetica and Sieglinde) in three Italian potato cultivation regions (Puglia, Sicily and Tuscany). RESULTS Sucrose and amino acids were not(More)
Ubiquitous computing is rapidly emerging as a framework for deploying mobile and context-aware applications. We focus on a new approach, and the resulting architecture, for implementing positioning services over ubiquitous infrastructures. Our driving idea is to estimate zones where mobile devices operate measuring the power level of wireless communications(More)
The provisioning of multimedia services with guaranteed Quality-of-Service (QoS) is currently an important research issue in computer engineering, especially in the networking and information management areas. In this paper, we concentrate on the QoS-based provisioning of discovery and delivery services of multimedia resources in the educational application(More)
The seed sector situation in Northwest Somalia is critical. The availability of food has decreased and many people are at risk of hunger. Food security can be restored by enhancing the local genetic resources and creating an efficient seed sector. Sorghum is important as a food and fodder crop in this region. It is close to Ethiopia, which is considered as(More)
The biological age difference among twins is frequently an issue in studies of genetic influence on various dental features, particularly dental development. The timing of dental development is a crucial issue also for many clinicians and researchers. The aim of this study was therefore to verify within groups of twins how dental development differs, by(More)
The effect of growth conditions (medium and photoperiod) on in vitro tuberisation and microtuber dormancy of the cv. Désirée (Solanum tuberosum subspeciestuberosum) and Imilla Negra (Solanum tuberosum subspeciesandigena) was evaluated. The short photoperiod and presence of CCC in the medium reduced the dry matter of plants as well as the size of(More)
