A Population-Based Approach to Study the Impact of PROP Perception on Food Liking in Populations along the Silk Road
Taste is one of the main factors determining food choices. Differences in PROP bitter taste perception have been implicated in individual differences in food preferences and selection. The present study examined associations between, PROP phenotypes, self-reported food liking and TAS2R38 polymorphisms, the major gene implicated in PROP bitterness, in six different populations of the Caucasus and Central Asia, located along the ancient Silk Road. Differences in the distribution of PROP phenotypes across populations were detected, with a higher frequency of super tasters in Tajikistan (31.3%) and Armenia (39.0%) and a higher frequency of non tasters in Georgia (50.9%). While no relationships were observed between PROP phenotypes and food liking using standard statistical tests, we used an approach based on comparison of distance matrices derived from these data. The first matrix compared the food liking ratings of each population to all others pairwise using the Kruskal-Wallis test (at p<0.00063), and the second one compared the distribution of PROP phenotypes across all populations in a similar manner calculating the chi-square statistic as a distance measure. A strong correlation between the two matrices was found (Mantel test: r = 0.67, p-value = 0.03), suggesting that the pattern of food liking across populations was closely related to the distribution of PROP phenotypes. This same relationship was not observed when TAS2R38 genotypes were substituted for PROP phenotypes in this analysis. Our data suggest that a population-based approach utilizing distance matrices is a useful technique for detecting PROP-related differences in food liking and can be applied to other taste phenotypes. © 2014 Robino et al
Clinical role of lipid transfer proteins in food allergy
Lipid transfer proteins are widespread plant food allergens, highly resistant to food processing and to the gastrointestinal environment, which have recently been described as true food allergens in the Mediterranean area, where they have been associated with severe allergic reactions to foods in patients without pollen allergy. In this review we analyze their molecular structure, biological function, and clinical relevance in food allergy
Analisi archeometriche sulla ceramica di età ellenistica di Adria: abitato e necropoli a confronto.
Studies concern the analysis of hellenistic pottery samples from the settlement and the burials of Adria (Ro, Italy). The aim of the analysis is to know the difference between settlement pottery and burial pottery, and if there are different places or different ways of production.
Provenance studies were characterized by Instrumental Neutron Activation Analysis (INAA) and the chemical data are submitted to multivariate analysis. Show that local origin of raw material, all samples are the same composition, but different technologies

Le ultime fasi del sito di San Cassiano di Crespino e le trasformazioni nell'entroterra di Adria
Tecniche edilizie nel complesso etrusco-padano di San Cassiano di Crespino (RO)
This paper focuses on the construction techniques in the Etruscan site of San Cassiano di Crespino (end of the 6th –
beginning of the 4th Century BC). In this settlement, located in the territory of Adria, the buildings are designed into
a coherent urbanistic project and present different building solutions.
Three structures had stone foundations, with wattle and daub or pisé walls and tiled roofs laid over them. Inside walls
were also made of perishable materials. Small service buildings were found in the site, entirely made of wood and
clay, with wattle and daub walls but also with a peculiar terra-cotta tile for some structural parts. All the different
building solutions show a considerable know-how and expertise of carpentry.
For different aspects, San Cassiano can be compared to contemporary Etruscan sites near the northern boundary,
represented by the Po River (where the settlement of Forcello di Bagnolo San Vito lays) and the Po Delta (where
Adria, Spina and San Basilio are located). At the same time, the presence of stone foundations and tiled roofs shows
close similarities with examples from Tyrrhenian Etruria, and especially from Padanian Etruria

Balancing QoS and power consumption in programmable 5G infrastructures
The advent of fifth generation is promising to push far more intelligence than today to the network boundary, hence boosting novel computing models based on fog/edge paradigms. The need for proximity in computation, coupled with various forms of mobility, will be responsible for dynamic shifting of workload within the system, with large fluctuations in resource usage. This eventually turns into poor energy efficiency of the whole infrastructure. However, improving efficiency usually deteriorates quality of service, hence the dilemma about how to balance these two contrasting aspects. In this paper, we propose a framework that leverages the increasing programmability of ICT infrastructures to pursue a linear relationship between power consumption and workload, while safeguarding quality of service. Our approach is based on workload consolidation and extensions to existing cloud management software. We collected both real measurements from an experimental testbed and performance analysis from simulations to evaluate the consolidation strategy in more complex environments
OpenStack extensions for QoS and energy efficiency in edge computing
Mobility has always been a big challenge in cellular networks, because it is responsible for traffic fluctuations that eventually result into inconstant resource usage and the need for proper Quality of Service management. When applications get deployed at the network edge, the challenges even grow because software is harder to hand-over than traffic streams. Cloud technologies have been designed with different specifications, and should be properly revised to balance efficiency and effectiveness in distributed and capillary infrastructures. In this paper, we propose some extensions to OpenStack for power management and Quality of Service. Our framework provides additional APIs for setting the service level and interacting with power-saving mechanisms. It is designed to be easily integrated with modern software orchestration tools and workload consolidation algorithms. We report real measurements from an experimental proof-of-concept
